Description

The invention relates to the field of medical equipment.

In medical technology, the design of the syringe has long been known. Syringe design options are numerous and also known. But they all fundamentally consist of several main parts: from the ampoule body containing the medicinal substance, the needle connected to the body, and the mechanism for squeezing the drug from the body through a needle having an outlet channel into the patient's body. For example, see the design of the syringe ampoule A.S. SU No. 1827264 dated October 11, 1990, A61M 5/00, 5/28, containing an elastic container body, a terminal on the body with a punctured membrane wall, a chamber with a soluble ingredient and a needle with a threaded nozzle. The camera, housing and needle with its nozzle are located separately, independently from each other. In the case there is a medicinal fluid, in a chamber bounded by membrane walls, there is a soluble ingredient (not liquid). When threading the chamber onto the housing outlet, and the nozzle with the needle is screwed onto the threaded part of the chamber, the membrane-walls are pierced with a needle, it is removed, and a general medicine with the ingredient dissolved in the chamber is obtained. The liquid with the ingredient dissolved in it is distilled from the housing into the chamber by pressing the walls of the housing with the needle removed. Having received the general mixed drug substance, they again put on the needle and inject the contents to the patient by pressing on the elastic walls of the body.

The disadvantages of the design of such a device are: the design is not high-tech, the main parts of the device are located separately, the needle must be removed, put on, the medicine must be mixed beforehand, this operation can be performed previously and in a separate container with deformable walls, to which the needle can be connected; the introduction of drugs is carried out only in one place, not in individual muscle depots, the needle is not rigidly installed on the body and may fail, when working in the field and in battle, using such a syringe design is inefficient, a lot of time is wasted dissolving the drugs and introducing the ingredients to the patient, mixing of drugs poorly compatible with each other is provided.

Another solution of the device for administering drugs is known, see p. RU No. 2238763 of 01.20.03, A61M 5/19, comprising a housing in the form of an ampoule comprising at least two deformable chambers separated by a longitudinal partition from one another to accommodate drugs, each of which is equipped with a transverse membrane inside and a needle made with a shank with the ends apart and installed in the housing opening with the possibility of movement and with a gap over the longitudinal partition and membranes. Before operation, the chambers are filled with drugs and sealed membranes in the chambers. When using the device, the needle is moved in the body, piercing the shanks of the membrane in the chambers, allowing the drugs to exit through the needle into the patient's body. The needle of such a device can be reusable and can be used in the field.

The disadvantages of this device are: the design of the device is difficult to manufacture, low-tech, slow drug administration, uneconomical, expensive at cost, low efficiency of its use, it is not possible to work with standard tubes-ampoules of drugs.

The closest solution is the design of a syringe tube called "Device for the introduction of drugs" according to p. RU No. 2248223 dated 12/30/2002, А61М 5/24, containing a housing comprising at least two chambers for drug placement, separated from each other and a needle mounted on the end of the body and having at least two output channels, each of which communicates with the corresponding camera of the body, made in the form of a tube of deformable material, while the outlet openings of the needle channels are spaced apart from each other. The device was developed on the basis of using the method of protecting the patient's respiratory center in case of severe mechanical injuries according to item RU No. 2238762 dated 12/30/2002, A61M 3 / M 3/00, A61P 11/16, 25/04, including simultaneous injection during one injection. the introduction of a respiratory analeptic and another drug that is poorly compatible with it, creating their separate drug depots in the muscle at the time of drug administration.

The disadvantages of the device are: the drug is not administered fast enough, the device is not technologically efficient and the product is effective, there is no data on the minimum distance between the output channels of the needle, because when you insert the needle into the patient’s body in different places, you must be sure that both output channels are intramuscularly fast absorption of drugs from the drug depot; there is no way to work with standard ampoules of different drugs and their quick change; insufficiently fast drug administration.

The technical result of the proposed solution is to increase the efficiency of using a syringe tube in the field and in combat conditions by increasing its multifunctionality, manufacturability, economy and reusability, reducing the time of administration of several drugs at once.

This result is achieved by the fact that in a syringe tube containing a deformable body, consisting of two containers separated from each other for holding medicinal substances, and a needle mounted on the end of the body, having two output channels, each of which communicates with the corresponding capacity of the body, equipped with outlet openings located at a distance from each other, the body containers are made in the form of standard ampoules with deformable side surfaces, and the needle is made of two metallic their capillary tubes, the internal openings of which are the outlet channels of the needle, moreover, several outlet openings are located on the lateral surfaces of the needle tubes, the distance from the end of the needle to the last outlet on one of the channels is at least 20 mm, the inlet ends of the needle tubes with inlets on the side the surfaces are located inside the ampoules, on the outside above the ampoules at the entrance to them they are bent, and these tubes are coated with silver on the outside and inside, while on each metal tube of the needle the polymer An acoustic tube with a blind end and with a longitudinal section along the generatrix of the tube with the closure of all external outlet openings of the metal tubes, the outlet openings on the needle channels being made in the form of a gap, and they are arranged alternately in relation to each other on different channels of the needle.

The invention is expressed in the aggregate of essential features sufficient to achieve the technical result provided by the invention.

The essential features of the proposed solution, which coincide with the features of the prototype, are: A - deformable body, consisting of two containers separated from each other for placement of medicinal substances; B - the needle is installed on the end of the body, having two output channels, each of which communicates with the corresponding capacity of the body, equipped with outlet openings located from each other at a distance.

Significant distinguishing features of the proposed solution are: B - body containers are made in the form of standard ampoules with deformable side surfaces; G - the needle is made of two metal capillary tubes fastened together, the internal openings of which are the outlet channels of the needle, moreover, several outlet openings are placed on the lateral surfaces of the needle tubes, the distance from the end of the needle to the last outlet on one of the channels is not less than 20 mm, the inlet ends of the needle tubes with the inlet openings on the side surfaces are located inside the ampoules, outside the ampoules they are bent at the entrance to them, and these tubes are coated with silver on the outside and inside; D - on each metal tube of the needle, a polymer elastic tube with a blind end and with a longitudinal section along the generatrix of the tube is tightly clad with the closure of all external outlet openings of the metal tubes.

Particular distinguishing features: E - exit holes on the needle channels are made in the form of a gap; G - outlet holes on different channels of the needle are arranged in relation to each other in alternating order.

The syringe tube is reflected in the drawings of figures 1-4.

The syringe tube of the proposed design is intended for the rapid administration of various medicinal substances, as well as for the rapid administration of simultaneously poorly compatible drugs with each other into the patient's body. The design of the syringe tube contains a deformable body consisting of two divided containers 1, 2 (Fig. 1) for accommodating various medicinal substances 3, 4, for example, a respiratory analeptic and other poorly compatible drugs, for example, an analgesic. A needle 5 is installed at the end of the casing. The containers 1, 2 of the casing are made in the form of standard plastic ampoules, the walls of which can be deformed (compressed) (figure 2). One end of the ampoules 1, 2 (Fig. 1) of the housing is tightly closed, and their opposite ends 6, 7 have outlet openings communicating with channels 8, 9, which are internal openings of the metal capillary tubes 10, 11, which are the needle 5. Capillary metal the tubes 10, 11 are fastened together and in each of them are made several outlet holes 12. Relative to each other, they are arranged in alternating order on the sides of the tubes. The outlet holes in these tubes are made in the form of a slit (Fig. 3) with a width of 0.5 mm and a length of 1.5 mm. The last outlet 13 of the tube 11 protruding above the other tube is made along its end. Subsequent outlet openings 12 of this tube 11 are formed on the side surface of the tube. The outlet 12 of the other tube 10 is made only on its side surface. The end of this tube of channel 8 is closed. The last outlet openings 12, 13 in the channels 8, 9 of the tubes 10, 11 are located at a certain distance with respect to each other. The distance "A" from the end of the needle of one of the channels 9, i.e. from its end face of the last outlet 13, to the last outlet 12 made on the side surface of the other channel 8, is made at least 20 mm. The input ends of the metal tubes 10, 11 of the needle 5 with the inlet holes 12 on the side surfaces are located inside the ampoules 1, 2. Outside above the ampoules, at the entrance to the ampoules, the tubes are bent. These tubes 10, 11 inside and out with inlets 12 are silver plated. On each metal tube 10, 11, the needles 5 are tightly dressed along the elastic polymer tube 14, 15 with a blind closed end and with a longitudinal section 16 along the generatrix (figure 2) of the tubes 14, 15 made of a material, for example, polyvinyl chloride or polyethylene. The tubes 14, 15 are dressed on the needle 5 so that they cover all the outlet openings of the outlet channels of FIG. 4. Each ampoule 1, 2 of the case is autonomous with respect to each other, contains its own drug 3, 4 in a liquid state and is connected to its output channel 8, 9 of the needle 5. The material of standard ampoules 1, 2 is made of a soft substance, for example, of polymer, soft metal (like a tube of toothpaste), capable of being pressed when pressed on the side surface of the ampoules (figure 2). The medicine in ampoules is contained in 1-2 ml. Capillary metal tubes are made of stainless steel 12X18H10T according to GOST with an external ⌀ 1-1.5 mm and are fastened together, for example, are sealed or welded. The open end ends of the capillary tubes with the inlet openings are bent and inserted into the outlet openings of the ends 6, 7 of the ampoules 1, 2. All the medicine in the ampoules goes into the inlet openings at the ends of the tubes placed in the ampoules. The inlets in different tubes are made alternating due to the preservation of greater rigidity of the needle. So, the ampoules 1, 2 of the syringe tube represent the body, and the metal capillary tubes 10, 11 fastened together, in which there are internal holes - channels 8, 9, represent the needle 5. In the inoperative state, the ampoules with the drugs are closed . And the needle tubes are closed with polymer tubes 14, 15 and placed in a sealed plastic case. Such a syringe tube can be administered to the patient as one or two drugs at once. In this case, an anesthetic can be placed in one ampoule, and an analeptic in another ampoule. As an analgesic, promidol or morphine can be used - these are analgesics, etimizol or naloxin can be used as a respiratory analeptic. Therefore, the device is effective when used in the field and in combat conditions, involves the use of different drugs, inserting the needle into standard ampoules (or into a standard syringe case) with various drugs. In combat and field conditions, it is necessary to inject drugs by injection through clothing, which can lead to suppuration of this injection area, as well as tetanus. But since the needle tubes are coated with silver (by means of electroplating), then during the injection of drugs along the channels of the needle tubes, bactericidal silver ions enter the drug depot during the injection. Silver ions are located in the injection channel, which ensures the effect of a “sterile” injection under extreme conditions. Additional holes made on the lateral surfaces of the needle channel tubes increase the absorption area of the drug substance into the body and, as a result, increase the rate of drug entry in extreme situations. The device is technological and economical to manufacture, because uses parts developed and manufactured by the industry. The needle can be used repeatedly, many times, which is also economical. When you enter as one medicine, therefore, one tube of the needle protrudes above the other, or two - the input process is much faster than with a standard needle.

Work with a syringe tube is as follows. In standard ampoules 1,2 there are various medications 3, 4. Remove the needle 5 from the polyethylene cover, remove the polymer tubes 14, 15 from the metal capillary tubes 10, 11 of the needle 5, wipe the needle with alcohol and insert it into the ampoules with the curved ends of the metal tubes, if you need to enter two drugs at once simultaneously. Intramuscularly, a needle 3 is inserted into the patient's body, pressing on the side surfaces of the body (ampoules) of a soft tube, drugs are squeezed out through the outlet openings of the channels 8, 9 of the needle 5 at the same time. Because these holes are located at a distance from each other, between the injection site of drugs is a layer of muscle. The injection site is called the drug depot. With the introduction of drugs that are poorly compatible with each other, one drug is an anesthetic, and the other drug is a respiratory analeptic. But you can enter medication and sequentially, first one, then another. If one medicine is administered to the patient, then one ampoule 4 is connected to the tube 11 protruding above the other tube 10. And a part of the needle, only the protruding tube 11, is inserted into the patient’s body. By pressing on the side surfaces of the connected elastic ampoule, the medicine is introduced through this tube 11.

The device is a syringe tube technologically advanced in manufacture: the manufacture of polymer ampoules is mass-produced, the capillary tubes that make up the needle are GOST standard, manufactured by industry, sealing metal tubes between them does not present technological difficulties. Therefore, the syringe tube is very economical to manufacture, is reusable, convenient and easy to use not only by medical professionals, but also by all users.

Using the proposed solution “Syringe-tube” according to the prototype allows to increase the efficiency of its use by increasing the manufacturability of the drug, reducing the time of drug administration, economy, more precise dimensionality between the output channels, which makes it possible to use one medicine in this needle, due to that in the design of the syringe tube containing the housing, consisting of two containers for accommodating medicinal substances, and a needle mounted on the end of the housing having two outlets channel bottoms, each of which communicates with the corresponding capacity of the body, equipped with outlet openings located at a distance, the capacity of the body is made in the form of standard ampoules, and the needle is made of two metal capillary tubes fastened together, the internal openings of which are the output channels of the needle, and The lateral surfaces of the needle tubes contain several outlet openings, the distance from the end of the needle to the last outlet on one of the channels is not less than 20 mm, the input con The needle tubes with the inlet openings on the side surfaces are located inside the ampoules, they are bent outside the ampoules at the entrance to them, and these tubes are coated with silver on the outside and inside, while each metal tube of the needle is tightly worn with a polymer elastic tube with a blind end and a longitudinal cut along the generatrix of the tube with the closure of all the external outlet openings of the metal tubes, and the outlet openings on the needle channels are made in the form of a gap, and on different needle channels they are arranged alternately with respect to each other okay. The syringe tube of this design is multifunctional and effective when used in the field and in combat conditions, as having various drugs, you can use their large nomenclature, in case of severe injuries and injuries, two drugs can be administered simultaneously with less loss of time, thanks to the design of the needle, you can use all the medicine in the ampoules (the presence of inlets at the ends of the needle tubes located in the ampoule openings ), you can use the needle repeatedly, it is stored separately from the ampoules in a closed plastic case and has a bactericidal effect. Parts of the device are commercially available by industry, namely capillary metal tubes, polymer protective tubes, it is not necessary to manufacture individual ampoules with partitions, therefore the syringe tube is technological and economical to manufacture, simple and reliable in operation. The syringe tube of the proposed design can be recommended for widespread use in ambulance first-aid kits, geologists, field surveyors, in units of special forces soldiers working in severe extreme conditions.
