- General information
1.1 Injection is a medical procedure involving the introduction of drugs into soft tissues using a syringe.
A medical syringe is a special device designed to administer drugs by injection.
Since this is a medical procedure, for the sake of safety, it is imperative to fulfill certain requirements for sterility (see clauses 1.3.3, 1.6), the injection technique and the selection of drugs used in this case (see clause 1.7).
1.2 The injections discussed here are divided into four types: intramuscular, subcutaneous, intradermal, intravenous.
1.3 Syringes are divided into disposable and reusable types. There are reusable syringes with disposable needles, which we will classify as reusable.
1.3.1 Disposable syringes of a wide variety of types are readily available in pharmacies. They are convenient to use, readily available and should be discarded after use. Their differences from each other are described below. If desired, they can be sterilized by boiling, as well as reusable (see paragraph 1.3.3)
1.3.2 Reusable syringes are practically a thing of the past due to the complexity of their maintenance in healthcare facilities. Sometimes they can still be found in the surgical departments of hospitals. They usually have a glass body and a metal or glass piston. However, due to their specific appearance, they are usually more attractive to medical specialists. Therefore, for those who managed to acquire such, we will pay special attention to their sterilization.

1.3.3 The most affordable sterilization method at home is boiling. (Before all actions, you should thoroughly wash your hands with soap and water.) This requires a clean metal dish with a lid, distilled water and patience to wait until the end of boiling and monitor the water level in the dish. If the water boils away, the precious instrument will become unusable. Do not use the same water two or more times. Distilled water is freely sold on tap in pharmacies that have a production department.
Disassembled syringes, needles and mandrels (thin steel wires for cleaning the channels of the needles), as well as metal tweezers are placed in the container. Disposable syringes are stacked unassembled, needles are separately stacked to them. In the disposable syringes themselves, the same water should be drawn in from the container with a plunger until the plunger stops. Water should be poured to about three times the level of the instruments. Put all this “soup” on low heat and cook for 30 minutes from the moment of boiling. The magnitude of the fire under the dishes can be adjusted by ear: the syringes make a characteristic sound when air bubbles rush past them.
After the specified time, the container must be removed from the heat and allowed to cool to room temperature. After that, without opening the lid, drain the water.
- do not reduce the boiling time, since there are bacteria that can withstand temperatures of 100 degrees C for a long time;
- you should not speed up the cooling process, since the glass parts of the syringe are extremely negative about rapid temperature changes, and the plastic from which disposables are made deforms and cracks;
- for the same reason, you should not speed up the heating process – only over low heat; it is best if you have a separate container for syringes;
- do not even try to use other water: the scale that forms is almost impossible to remove.
1.3.4 Assembling the reusable syringes before injection.
To do this, you need a sterile container with low edges (it can be sterilized separately). For those who have also acquired a special metal box for syringes, everything is simplified, since you can use the lid. Another good option is a medical enamel tray. (In general, special boxes and trays can be found at medical supply stores, and I recommend getting them even if you are using disposable syringes.) And also another tray (container) for dirty tools.
So the assembly. You need to remove the lid and put it next to it, sterile side up. Take out the tweezers, then the syringe with tweezers, and take it in your left hand (for right-handed people). With tweezers, remove the plunger of the syringe and carefully insert it into the syringe. Secure the piston (if there is a special mount) by hand. Then, with tweezers, pull the needle of the required size by the cannula and put it on the syringe. You can fasten the needle to the syringe with your fingers, holding it by the cannula, gently rubbing in small circular movements. The syringe can now be placed in a sterile tray, and the tweezers can be returned to the syringe container, which should be covered with a lid.
- if during the assembly process some part of the syringe touches non-sterile surfaces (for example, as a result of a fall), then it should be sent to the tray for dirty instruments;
- it is allowed to make injections with the same syringe, but only to one person (AIDS, etc. do not sleep), while changing the needles for each injection and not using different medications. In this case, the syringe after injection must be returned to a sterile tray;
- if after the injection the needle is not removed from the syringe, then it is easier to do this with a piece of sterile cotton wool, wrapping it around the cannula of the needle;
- assembly of disposable sterilized syringes is carried out in the same way.

1.3.5 Medicine kit
Take the ampoule in the left hand (for right-handers). With your right hand, make a file with a special file. With a sterile alcohol napkin (cotton wool), wipe the upper part of the ampoule in the area of the cut and, using the same napkin, break off the top of the ampoule in the direction opposite to the side of the cut. The ampoules should open without undue effort. It is better to repeat the file than to get the glass crumb in hand. After that, fold the napkin with the broken part of the ampoule into a special tray for ampoules and used napkins. To set the medicine, the ampoule must be clamped between the index and middle fingers of the left hand, the syringe is in the right. Gently, without touching the walls of the ampoule, insert the needle into the ampoule, hold the syringe by the cannula with the thumb and ring fingers of your left hand. And holding the syringe with the index and middle fingers of your right hand, pulling back the plunger with the thumb and ring fingers of your right hand, draw up the medicine. After that, remove the empty ampoule into the ampoule tray, directing the syringe with the needle up, remove air from the syringe. Place the syringe in a sterile tray.
Notes:
- a tray for used napkins and ampoules is desirable, since ampoules are round, easily roll on the table, fall, and are very easily crushed, and if you are not a fan of the thrill of glass in your leg, then keep this in mind;
- it is not necessary to expel all air bubbles from the syringe too carefully, contrary to popular belief, this does not affect the painfulness of the injection, and a small amount of air will fit in the cannula and needle;
- by the way, medical workers have diametrically different opinions about the fatality of air ingress during even intravenous injection.
1.3.6 After use, reusable syringes should be rinsed in distilled water. If the needle gap is clogged, then it must be cleaned with a mandrel. Store reusable syringes in a dried form in a special container (you can use the same one in which they are sterilized) at room temperature out of the reach of children.
1.4 Syringes are also divided according to the volume and size of needles depending on the injection to be done. The syringe volume depends ONLY on the amount of medication that needs to be injected. Syringes are usually 1, 2, 5, 10 and 20 ml. For intramuscular injections, needles with a length of 35 mm or more are used, depending on the thickness of the subcutaneous fat at the injection site. For obese people with intramuscular injection in the gluteal region, needles with a length of at least 40 mm should be used, for children from 25 mm. For subcutaneous injections, needles from 15 mm to 30 mm are used, however, needles for intramuscular injections can also be used, but they should not be inserted to their full length. For intradermal injections, needles up to 15 mm with a short cut are used. For intravenous injections, needles with a diameter of 0.8 mm and a length of 40 mm are used.
The packaging of disposable syringes is always marked, for example: 5ml, 0.8×40, which means a volume of 5 ml with a needle with a diameter of 0.8mm, a length of 40mm.
1.5 Disposable syringes with broken packaging, stored in a contaminated place and with an expired shelf life should be discarded or sterilized (see paragraph 1.3.3). You shouldn’t risk it for 3-5 rubles. (in Ukraine, syringes are in the region of 50-90 kopecks – proofreader’s note).
1.6 Rules of anti- and asepsis.
1.6.1 The room needs to be vacuumed and wet cleaned. The table on which the instrument will be located before the start of the session must be wiped with a clean napkin dipped in 70% alcohol solution (a bad option is vodka). Prepared medicines are laid out on the table (see below), a bottle with 70% alcohol solution (or vodka), sterile cotton wool, or, what is better, sterile gauze napkins (they are sold in any pharmacy), a tray (container for used ampoules, cotton wool, napkins).
Ready-made alcohol wipes are sold in pharmacies. It is better not to use them, since they are small, inconvenient and there is little alcohol, it fizzles out quickly.
1.6.2 Hands should be thoroughly washed with soap and warm water. Nails should be clean and trimmed (just clean for ladies). Hands should be wiped with an alcohol wipe immediately before injection.
1.6.3 Syringes, ampoules, cotton wool (napkins) should only lie on the table. Anything that is accidentally dropped is sent to the tray. In addition to ampoules, you can simply wipe them with an alcohol wipe. The dropped parts of the reusable syringes are sent to the container for the dirty instrument. Do not be fooled by rubbing them with alcohol. The problems that may arise in this case will spoil your comfort for a long time.
1.6.4 The injection site (especially if you do several injections at the same site) should first be wiped with an alcohol wipe over a large area, perhaps even the entire injection area. Then another tissue paper to a specific part of the skin at the injection site.
1.7 Medicines.
For medfetish sessions, it is best to use water for injection, or saline (NaCl 0.9%). It should be remembered that drugs, including vitamins, etc., are drugs that have a certain effect on the body, which can lead to an inadequate reaction, which a non-specialist cannot always cope with. Do you need these problems?
And water and saline do not have any therapeutic effect and are freely sold in pharmacies. It is necessary to dwell in more detail on the features of these drugs, let’s call them all the same.
The saline solution has practically the same Ph density as the body tissues and is therefore almost painless when administered. It is convenient for those who are interested in the session itself with its formal side, expectations, external attributes such as postures, nudity, sounds of opening ampoules and characteristic sounds when handling syringes (especially reusable ones). But at the same time, the excessive pain of injections is not satisfied.
On the contrary, water for injection, due to the Ph mismatch, is very painful when injected. Therefore, it is more interesting for those who care about the painfulness of injections. For those who consider it not painful enough, I advise you not to look for anything else, because those few drugs that are actually more painful are really dangerous if used uncontrolled. As a consolation, you can recommend finding the position, place and method of the most painful injection (see injections). For those looking for an average soreness between water and saline, you can mix them in the same syringe, thus changing the Ph, and achieve optimal sensations.
Notes:
- it is not recommended to use ordinary and even distilled water for injections. Water for injection in ampoules is not the same thing, and its price is not high.

- Injection
2.1 Immediately, I note that in order to avoid complications, it is recommended to acquire an anatomical reference book in order to avoid getting near the joints, large nerves, into large blood vessels and periosteum.
2.2 Intramuscular (i / m) injections are most often practiced by medical specialists, and therefore we will start with them.
2.2.1. Place of introduction.
IM injections can be made into all major muscles of the body: gluteal muscles, thigh muscles, calf, deltoid muscle of the shoulder. The indicated muscles are listed according to the degree of pain in the injections upward. Others can be used, but this already requires a good knowledge of anatomy. Not recommended for beginners. I will dwell in detail on the gluteal muscles, as the most commonly used ones. The outwardly known upper quadrant can be defined as follows: a horizontal line runs from the lower edge of the coccyx to the hip joint. The vertical line runs approximately in the middle of the butt plane. However, there are anatomical features in each person, and therefore a slight deviation from these lines in the direction of increasing the area is permissible. In this case, it is necessary to probe the location of the pelvic bones with your fingers so as not to get too close to them. I will also note that injections are more painful, carried out closer to the places of muscle attachment. However, once again I strongly recommend that you study the anatomical structure of the body.
The position of the “patient”
Typically, meditation practitioners prefer certain positions. It should only be noted that the position should be such as to prevent unexpected sudden movements of the body, for example, at the time of insertion of the needle, this is especially important when using reusable syringes, the needles of which sometimes bend and break from such movements. Therefore, standing, sitting, lying – everything is permissible.
It should be noted for amateurs that the injection is significantly more painful when the muscle is stretched (and not tense, as many think). So, for this category, it may be preferable to postures in which the leg is bent at the hip joint, for example, sitting on a stool, leaning forward, lying on its side, knees pulled to the stomach, sitting on the heels, etc.
Needle insertion technique
The painfulness of an injection generally depends only on the skill of the person giving the injection, but not on the size of the syringe (needle). For painless needle insertion, the “patient” should lie on his stomach, press the skin at the injection site with the thumb and forefinger of his free hand and stretch it between the fingers. The syringe must be held so that the little finger is on the cannula (does everyone know what a cannula is?), The index finger is on the piston rod, the thumb and the rest of the fingers are on the syringe itself. The needle must be sharply, practically with a blow, inserted into the space between the fingers of the other hand. After a while, you will stop hitting your fingers:. Then transfer the fingers of your free hand to the plunger of the syringe and inject the medicine. Naturally, it is most painful to insert the needle slowly, gradually passing through all layers.
Notes:
- if, when inserting the needle, you hit a hard one, you need to remove the needle and inject in another place;
- in the case of the “patient” position with bent legs, remember when inserting the needle about the perpendicularity of the puncture, otherwise the needle will not enter the muscle.
Administration of the medication
Everything is simple here: the faster, the more painful.
For those who believe that water is not painful enough, I recommend combining everything together: posture, place, technique for introducing the needle and water, and the amount of water. 2ml and 10ml – different sensations.
Notes:
- it is not recommended to inject more than 20 ml in one injection. In general, 5-10 ml is optimal. If it is not enough, make 10 injections of 5-10 ml in each half of the priests;
- The “slap” technique of needle insertion, which is familiar to many, is undesirable, since, firstly, it is difficult to control the correct insertion of the needle, and, secondly, you should not touch the disinfected injection site with anything. Therefore, we will not even begin to explain how this is done.

2.2.2 IM injections into other muscles are not fundamentally different. It is only necessary to take into account the depth of the needle insertion.
2.2.3 Another commonly used IM injection site is the gastrocnemius muscle.
Place of introduction
The middle third of the posterior surface of the gastrocnemius muscle. Let me remind you about the anatomical reference once again. Well, by eye, the muscle (more precisely, the muscle) is located between the popliteal space and approximately the middle of the lower leg. Below is the tendon, in the lower part ending in the so-called Achilles. Thus, if you visually divide the entire lower leg into 6 parts, then the injection site is the 2nd part from the top. The thickness of the subcutaneous fatty tissue in this place usually does not exceed 1 cm. Therefore, both short needles (20-25 mm long) and long (40 mm) needles can be used, but without inserting them deeper than 20-25 mm.
Notes:
- you should not use the first part of the muscle from above, because you can get into large blood vessels and nerves that are located in the popliteal region;
- do not use the third part from above, since you can get into the tendon (it hurts a lot, heals for a long time);
- Do not inject into the lateral surfaces of the muscle because of the possibility of getting into the blood vessels and nerves again and close to the periosteum.
The position of the “patient”
It is best to use a position in which the lower leg is fixed, namely, lying on your stomach, kneeling, standing on the floor or a chair, standing on the floor, your leg on a chair, etc. That is, it is not recommended to keep the lower leg suspended for the same reasons as and for intramuscular injection into the gluteal muscles.
Needle insertion technique
Completely similar to gluteal injections. For some fetishists, the tiptoe position of the patient is of particular interest. However, it should be remembered that it is rather difficult to stand in this position for a long time, and therefore it is possible to change the position of the “patient” and displacement of the needle in the muscle tissues. By analogy with injections in the gluteal region, you can pull the toe of the foot towards you, and then the injection will be more painful.
Administration of the medication
The same thing – the faster, the more painful.
The optimal amount of the injected substance is 1-3 ml.
2.3 Subcutaneous (s / c) injection.
With subcutaneous injections, drugs are injected into the subcutaneous fatty tissue.
Place of introduction
Almost any place where there are no large blood vessels, far from the joints and the thickness of the subcutaneous fat is at least 0.5 cm.More specifically: the outer and back surface of the shoulder, butt, now almost all, with the exception of the area on which they sit directly, the front , inner and back of the thigh, abdomen, but not closer than 2 cm from the navel, scapular region of the back.
The position of the “patient”
Any comfortable position is acceptable, in which the injection site is relaxed, the skin is not taut. The degree of pain is almost independent of the area. If only subjectively. Needle insertion technique.
It is important to get into the fatty tissue; for this, the skin needs to be gathered into a fold and the needle is inserted into the base of the fold at an angle of approximately 45 degrees. The painfulness of the puncture depends only on the needle and its speed of insertion.
Administration of the medication
The same thing – the faster, the more painful.
For those who think the water is not painful enough, try injecting 2-3ml of water subcutaneously.
Notes:
- It is not recommended to inject more than 5 ml in one injection. Optimally 1-3ml.
2.4 Intradermal (i / c) injection
This is for fans of school memories of the Mantoux reaction.
- Injection site.
Inner forearm, abdomen, inner thigh, skin area above the calf muscle.
- The position of the “patient”.
The limb should be fixed in a horizontal position.
Introduction technique
Special blunt needles with very small diameters are required. The needle is inserted with the lumen upward almost parallel to the skin until the cut is hidden in the thickness of the skin. For a reference point, when the drug is injected, a small lump should swell.
Notes:
- It is not recommended to inject more than 0.1 ml of the drug. For super masochists, try with water for injection. You should like:
2.5 Intravenous injection
We will only mention this type of injection as possible for the purposes of medfetish. However, doing them safely requires good skill and training by an experienced technician. Therefore, it is not recommended to study them on your own.
