Description

The invention relates to medicine, in particular to the section of proctology and can be used in the treatment of rectal diseases and to reduce scars and adhesions in the postoperative period.

Known rectal catheter manufactured by MEDICOPLAST international GmbH, Germany, intended for irrigation and administration of drugs. It consists of a 40 cm long polymer tube with an open end connected to the connector and two side holes near the opposite - distal - rounded end. The rectal catheter is presented at retail in Russia, information about it is available on the Internet at http://www.medisign.ru/catalog/gastroenterology/u/ and is selected as a prototype.

The disadvantage of this rectal catheter is that with its help it is impossible to administer a suppository medication, therapeutic cream or gel.

The task to which the claimed utility model is directed is to expand the arsenal of technical tools used in the treatment of rectal diseases.

The problem is solved in that in a rectal catheter containing a tube of finite length with an open end and an opposite - distal - rounded end, the rounded end is made with variable geometry by dissecting the hollow sphere of the rounded end into several sectors; another tube is coaxially placed inside the tube, one end has a flange at its end, which abuts against the end of the open end of the outer tube, and the opposite end ends at the cut-off border of the sphere of the rounded end; a plunger with a shank is placed in the inner tube, the shank is brought out through the open end of the tube and connected to a handle restricting the movement of the plunger toward the distal end; on the outer tube there is a flange.

The first embodiment of a rectal catheter is intended for insertion of a suppository, therapeutic cream or gel, and therapeutic agents from a combination of individual therapeutic formulations.

In the second embodiment, the task is solved by the fact that in a rectal catheter containing a tube of finite length with an open end and the opposite - distal - rounded end with several side holes near the rounded end, another tube is placed coaxially with the other tube, one end of it has a flanging end which abuts against the end face of the open end of the outer tube, and the opposite end ends at the border of the side openings near the rounded end; a plunger with a shank is placed in the inner tube, the shank is brought out through the open end and connected to the handle; the movement of the plunger toward the distal end is limited by the plunger itself; on the outer tube there is a flange.

The second embodiment of a rectal catheter is more atraumatic, but is intended only for the introduction of a therapeutic cream or gel.

In the third embodiment, the problem is solved in that in a rectal catheter containing a tube of finite length with an open end and the opposite distal catheter with an open end, the distal end of the catheter tube is rounded off the tube end around the perimeter, a plunger with a shank is placed inside the tube, the plunger shank is withdrawn through the open end of the tube to the outside and equipped with a handle restricting the movement of the plunger towards the distal end; Outside the tube there is a flange.

This embodiment of a rectal catheter is intended primarily for the administration of a suppository, but does not exclude the administration of a cream and gel.

The essence of the claimed technical solution lies in the fact that by placing a plunger with a shank and handle inside the catheter, performing the distal end of the catheter with the ability to insert into the catheter and then using the plunger to remove the suppository or treatment cream and gel, providing the catheter with a flange, it was possible to ensure the catheter was inserted without serious consequences in the rectum to a regulated depth, use a plunger to move the suppository, or other therapeutic composition, up to the exit from the catheter is guaranteed to the right point; thus, it was possible to expand the arsenal of technical means that ensure the convenience, hygiene of administration and the effectiveness of using suppositories, the use of therapeutic formulations of several separate solid substances or creams and heliums, that is, to increase the possibility of using therapeutic agents in the treatment of rectal diseases and to reduce scars and adhesions in the postoperative period.

A removable external tube provides the convenience of laying a therapeutic cream or gel into the catheter, a therapeutic composition of several separate solid substances, a flange allows the catheter to be inserted to the required depth no more. If the flange is made movable along the tube, then the depth of insertion of the catheter can be adjusted. If you graduate the tube into which the healing cream or gel is placed, then you can control the portion of the therapeutic substance that is placed in the catheter.

The essence of the proposed technical solution is illustrated below by a description of its design and operation with reference to the accompanying drawings, which depict:

12 is an embodiment of the placement of the flange on the outer tube of the catheter.

A rectal catheter in the first embodiment contains: a circular elastic tube 1 of finite length, one end of which is open, the opposite - distal - rounded elastic end 2 has a variable geometry; placed inside the coaxial tube 3 with flanging 4; a plunger 5 inserted into the tube with a shank 6, while the shank is brought out through the open end of the tube and connected to a handle 7 restricting the movement of the plunger toward the distal end; placed on the outer tube flange 8;

in the second embodiment contains: a circular tube 11 of finite length, in which the distal rounded end 12 is made with several holes on the side near the rounded end; other elements - according to the first option;

in the third embodiment, contains a tube 13 of finite length, in which the distal end 14 is made with a rounding of the end along the perimeter; other elements - according to the first embodiment, with the exception of the inner tube.

The operation of a rectal catheter with variable geometry of the distal rounded end is as follows.

In the sterilized assembled catheter, hold the tube 3 by the flange 4 with one hand, pull the tube 1 with the other hand. Insert gel 9 or suppository 10 into the tube 3 from the side of the distal end and put the tube 1 back on until it stops. A catheter is inserted into the rectum until the stop of the flange 8 and, using the handle 7, the shank 6 is moved, and with it the plunger 5 to the stop. In this case, the spherical sectors of the distal rounded end 2 in contact with solid substances of the treatment composition (or with the suppository), and then with the plunger, expand and release the substances of the treatment composition (suppository or gel). After this, the catheter is brought out.

The operation of a rectal catheter with a distal rounded end 12 with several openings near the rounded end is different in that the catheter is filled only with healing cream or gel and squeezed out the treatment composition through the side openings near the rounded end or through the lateral and upper openings performed by the rounded end with a hollow sphere.

The operation of a rectal catheter with a rounded end face of the distal end 14, filled with a suppository or treatment gel, is characterized in that there is no operation to put on the tube 13. It is more technologically advanced in production.

The catheter parts are made of polymeric materials, which are now used in the medical industry, by molding on serial equipment, which is currently used in production.
