Description

A useful model of a device for intracavitary administration of drugs including paraffin - an ozocerite mixture and is intended for the complex treatment of various obstetric and gynecological pathologies and proctology.

The invention relates to the field of conservative methods of medical and physiotherapeutic treatment, in particular in obstetrics and gynecology, proctology.

The route of administration of drugs to the vagina and rectum is unique, since drugs subjected to absorption by their mucous membranes, due to the peculiarities of venous and lymphatic drainage from these organs, enter the lower vena cava, which delivers them to the heart bypassing the liver, which prevents the destruction of drugs liver cells immediately after administration and eliminates the adverse effects of drugs on the liver cells themselves.

However, due to the lack of devices for introducing drugs into the rectum that meet today's aesthetics, the indicated original and harmless route of administration of many drugs remains undeservedly unclaimed, which can also be used both in inpatient and outpatient settings and independently the patient when performing the procedures prescribed by the doctor at home, that is, on an outpatient basis due to the simplicity of the device and the convenience of its use, as well as the disposability of the consumables of the device.

Of the known domestic analogues, it is necessary to indicate: “Syringe” ”(RU 2008023 02.28.94. Bull. No. 4) intended for the administration of drugs by injection, while the front of the syringe is tight, and the back is elastic containing the piston from the outside, in the front the same part of the syringe contains a narrow tip for the needle, which makes it absolutely unsuitable for the introduction of "thick" drugs; “Device and method for intracavitary administration of drugs” (RU 96 122 173. Date of publication of the application 10.12.1998.) With a non-metallic working part containing holes with liquid medicine passing through them by supplying and discharging an ozone-oxygen mixture for 8-10 procedures and with a non-working part made of metal.

Of the known foreign analogues, the “Actuator mechanism” (JP 360781 B2 11056874 A 06/18/1998) containing fixing links with a capsule or a cartridge filled with a paste-like mass and equipped with a stop should be indicated

serving to clamp them to the actuator in the direction of extrusion of the paste used in prosthetics, however inconvenient to use by our patients in outpatient treatment.

A common drawback for these analogues is the lack of the ability for the patient to independently use these devices to perform the prescribed medical procedures.

The closest to the utility model, the prototype is the "Gel-Navrotsky apparatus for intracavitary ozokerite-paraffin treatment" (Aut. St. No. 257698, 11/20/1969. Bull. No. 36) the container of which is filled with pre-heated preparation, mixed with a long mixer and final mixing with a diffuser and also equipped with a rod with a piston and a handle, the axis of which is equipped with screw thread.

A disadvantage of the known design is:

1. the lack of a prototype of a pre-prepared single-use container, which is especially important in the prevention of transmission of infectious diseases;

2. the inability to preheat the treatment mixture outside the device, the prototype is heated in a thermostat, and the heating is carried out by placing a heating element in the form of a nichrome wire in the wall of its cylinder, which is also unsafe for the patient;

3. The prototype tip is also not disposable;

4. the lack of the tip of the ability to deviate from the longitudinal axis of the prototype, which complicates its use and does not exclude injury to the surface of the mucous membrane of the abdominal organs.

5. the obligatory participation of both hands of the patient when administering drugs using the prototype limits the patient’s stability, when a squatting position is chosen at the time of introduction.

6. the prototype lacks the ability to visually monitor the procedure, which is alarmingly suspicious patients, which is often found among women with chronic inflammatory diseases, causes a feeling of excitement and discomfort.

The objective of the invention is the creation of a useful model of a device for intracavitary administration of liquid, ointment and mud drugs, expanding its therapeutic capabilities and reducing the risk of possible complications favorably different from analogues and prototype allowing:

1) to increase the therapeutic capabilities of the device by giving it the ability to expand the range of injected drug media;

2) ensuring the disposability of the tips and containers for drugs introduced into the cavity of the organs that are subject to and accessible to radiation sterilization, and making the device itself possible to be an individual use device;

3) providing the device with the ability to provide visual control of the procedure with the elimination of feelings of anxiety and discomfort;

4) providing the device with one-handed use;

5) giving the tip of the device the ability to fulfill its purpose with a deviation of its axis from the longitudinal axis of the entire device, which will reduce the likelihood of injury to hollow organs.

The device consists of four functionally unified, but structurally separated parts, namely: a cylindrical medicinal reservoir of the container 1 (hereinafter the container), a mechanical injector of the extruder 2 (hereinafter the extruder) and a front cover 3 with a tip 4.

The plastic front cover 3 (hereinafter - the cover) is made of a cylindrical shape 2 mm thick, 1 cm long and with an internal diameter of 1 cm with internal thread. On the axial line in the upper wall of the lid 3, a tip 4 with an inner diameter of about 3 mm is hermetically fixed, the non-working end 5 of which protrudes inside it to a depth of about 2.5 mm in the form of an oblique cut serving as a perforator 6 when screwing the lid 3 to container 1.

Mounting 7 is made on the outer wall of the lid 3 in the form of a truncated pyramid with a height of about 2.5 cm with a longitudinal selection of plastic approximately 2.8 mm wide and 5 mm deep serving as a place for fixing the tip 4 with its subsequent placement in the packaging to be sterilized together with the lid 3, and after connecting the latter to the container 1, the mount 7 provides a portable location of the tip 4 in parallel to the container 1.

At a distance of 1 cm from the front wall of the lid 3, the tip segment 4, approximately 3 cm long, is made in the form of a corrugation 8, which makes it possible to change the angle of the tip position, which eliminates trauma to the surface of the hollow organs when it is used, while ensuring its convenience and comfort operation, as it allows the patient to carry out the procedure in a position convenient for him.

The working end of the tip 4 is made tight elastic of transparent medical plastic in the form of a tube with an inner diameter of 3 mm and a length of 10 cm, three spherical thickenings are attached to the outer wall: the first protective spherical thickening 9 (hereinafter referred to as the protective thickening) is made at the very beginning with the outer with a diameter of 4 mm and serves as a warning moment when leading the tip 4 into the hollow organ protecting it from injuries due to the streamlining of its spherical surface with axial passage through it of the channel of the tip 4; the second restrictive spherical thickening 10 (hereinafter referred to as the restrictive thickening) is made at a distance of 4 cm from the beginning of the working end with an outer diameter of 6 mm and serves as a restrictive reference point of a sufficient depth of immersion of the tip for introducing drugs into the rectum and, at the end, the third manipulating spherical thickening 11 (hereinafter - manipulation thickening) is made at its very end, at a distance of 9 cm from the beginning of the working end with an external diameter of 10 mm and serves as a place for the patient’s fingers to be inserted AI and placing the tip of the vagina with the safety, convenience and comfort during the procedure.

The container 1 is a hollow transparent cylinder with a conical shape of its ends and is made of durable, easily bendable, poorly stretchable plastic with a wall thickness of 0.5 mm, pre-filled with a finished dosage form of the required treatment volume, hermetically packed (by the type of vacuum packaging), non-working the end of which, at the end of its conical shape, is symmetrically flattened in the horizontal plane and sealed tightly tightly by temperature soldering in such a way that the welded walls are not cut, and continue for at least 2 cm and a width of 3 cm with a thickness of 1 mm, forming the so-called reinforcing strip 12.

The working end of the container 1 is made in the form of a cone 13, made at an angle of 45 degrees from the outer edge of the container 1, and on the top of the cone 13 is made, in the form of a hollow cylinder, approximately 1 cm high with an external thread, a cylindrical threaded

the latch 14 (hereinafter - the latch) the top of which is hermetically tightly closed with a thin, made, for example, polyethylene or foil, membrane 15.

The above described device of the container 1 is indicated for the administration of a medicinal substance in a volume of up to 30, 40, 100 ml or more. However, with the help of the device it is possible to administer significantly lower volumes of drugs, including one ml., Filled into a container, which in this case has some features, but with the obligatory implementation of a standard threaded fastener 14 on its working end. In the case of filling containers small volume liquid dosage form, it can be introduced by simply squeezing the container with your fingers, without the help of an extruder, due to the small size of the container. In such cases, in order to exclude the under-supply of the desired therapeutic volume of the drug from a container of small capacity, for example 1 ml., Produce:

A) the implementation of the threaded lock 14 and the tip 4 with their smallest inner diameter (clearance) equal to a tenth of a mm, sufficient for the flow of a solution of the drug in it;

B) in order to prevent and prevent the reverse intake (suction) of the drug into the cavity by the tip into the lumen, it is performed on the inner walls of small containers, in the longitudinal direction, along the midline of the strip retainer by making a lock on the inner surface of the walls of the container in the form of a semicircular ridge (1 mm in diameter) and the corresponding size and profile of a groove made opposite it, on the opposite inner surface of the extruder, which as it empties onteynera contact with dip the comb into the groove, and the formation of a kind of lock.

The extruder 2, in turn, is assembled from two parts: the casing 16 and the clamping scaphoid handle 17. The casing 16 is made in the form of a durable transparent plastic cylinder, with a thickened thickened along the outer surface of the lower half of the cylinder and easily bent into the inside elastic and thinned to 0.5 mm upper half of the cylinder body 16.

The cavity of the cylinder of the housing 16 is made with dimensions completely corresponding to the outer dimensions of the container 1 with only one difference - the ends of the plastic cylinder of the housing 16, so that in its conical front of its working end, a central hole 18 is made along the axial line, and the rear 1/3 of the non-working end body 16 is devoid of its upper elastic half, which allows you to enter

the container 1 through the thus formed cutout in the cylinder cavity of the housing 16 with the removal of the threaded lock 14 through the corresponding, in size and purpose, made along the axial line of the housing 16 of its Central hole 18.

On the upper surface of the non-working flat end of the lower half of the cylinder of the housing 16, a clamping pad 19 (hereinafter referred to as the pad) is made, in a horizontal plane, up to 0.5 cm thick, 3 cm wide and 2 cm long, with its corresponding length of the reinforcement placed on it strip 12. The non-working end of the pressure pad 19 itself is made thickened up to 1 cm and up to 3 cm wide with a rounded smooth edge and giving it a "solid" shape, with a small flat magnet soldered in its right side wall, an axial cylinder 20 with a diameter of 1 cm.

The axial cylinder 20 is designed to perform the axis of rotation by placing on it, by lateral advancement on it, corresponding to it with its "cavity" dimensions, made on the working end of the scaphoid handle 17, hollow, with an inner diameter, respectively, of 1 cm, of the connecting hollow cylinder 21 (hereinafter referred to as a hollow cylinder), in the longitudinal direction of the lower half of the rear wall of which a cutout 22 is made of a width of about 8 mm, which serves to draw ribs along it, the edges of the pressure pad 19 of the housing 16, with such provision ohm, the immersion effect axial cylinder 20 the hollow cylinder 21 of the working end of the handle 17 of the navicular.

The width of 8 mm of the cutout 22 allows the scaphoid handle 17 to move in a range sufficient for immersion in the casing 16, which begins by pressing it with the reinforcing strip 12 to the pressure pad 19 of the casing 16 with subsequent uniform and smooth immersion of the scaphoid grip 17 in the casing 16 with simultaneous bending inside the container 1 with the upper half of the housing cylinder 16, which is easily bent along with it into the elastic and thinned to 0.5 mm, upper.

The hollow cylinder 21, on the right edge, is closed by a plug 23 with a small flat round-shaped magnet soldered in the center of its wall coinciding in position, when the device is assembled, with the same magnet soldered in the right side wall of the axial cylinder 20, which allows the connection of the hollow cylinder 21 with an axial cylinder 20 without the need for external influences.

The symmetrical placement of small magnets also ensures the fixation of the connection of the axial cylinder 20 and the hollow cylinder 21 while maintaining their mobility around their rotation axis (similar to the movement in the knee joint or in the door canopies) with the participation of their smooth surfaces.

The scaphoid handle 17 is made with the shape and dimensions of its convexity corresponding to the dimensions of the inner cavity of the lower half of the plastic cylinder of the housing 16 minus 1.5 mm consisting of: a) doubled wall thickness of the container 1 (lower and upper with a thickness of 0.5 mm) and b) - 0.5 mm - the wall thickness of the upper half of the cylinder of the housing 16, which, when pressed against it by the bulge (edge) of the scaphoid handle 17, is smoothly dosed and gradually plunges into the lower half of the plastic cylinder of the housing 16, thus pouring without a remainder content of the container 1, after being placed in the cavity of the cylinder housing 16. Thus, squeezing the container 1 is carried in the direction from the contents of the non-working end of the container 1 toward its operative end.

The front cover 3 with a tip 4 is made of disposable medical plastic and packaged in a single vacuum polyethylene container to be installed, conventional radiation sterilization and are disposable.

The device is used as follows. Preparation of some components of the device for use is reminiscent of the assembly of a transformer: the container 1 is placed in the cylinder cavity of the housing 16, and, accordingly, smoothly and without special effort, the bottom of the scaphoid handle 17 is immersed in this, we require the following tasks:

moving the medicine into the screwed cover 3 to the latch 14 of the container 1 and with perforation of the membrane 15 and into the tip 4. If necessary, the drugs 4 are inserted into the rectum until the restrictive thickening 10 is introduced, when drugs are introduced into the vagina, to the fingers placed on the manipulation thickening. After the procedure, the container and cap with the tip are sent for disposal.
