Description

The invention relates to the field of medical technology, in particular to improving the performance of catheters inserted (for example) into the bladder.

The essence of the invention lies in the fact that after surgery, a catheter is inserted into the bladder to drain urine into an airtight bag. In the healing process is the rejection of parts of the tissue and the accumulation of salt toxins. The hole in the catheter is often clogged (especially at night) and medical attention is required to clean the mouth of the catheter by pumping urine with a special syringe, which is installed instead of an airtight bag with a tube, which requires special conditions and the employment of medical personnel.

A device is known: "A method for regulating the flow of urine in the urethra and a system for its implementation." This invention relates to a method and mechanism for retention of premature urine output and consists of a catheter (patent US 4813935, class A 61 M, 25/00, 1989) and an elastic cavity in which a one-way valve is installed on the outlet channel for urine discharge , which does not allow spontaneous emission of urine until you squeeze the elastic cavity, as a result, a mollusk-like valve consists of two halves located at an angle and resting on each other (patent 2097071 C1, 6 A 61 M 29/02 from 22.10. 90, published November 27, 1997. Bulletin No. 33).

The essence of the invention lies in an individual method of restoring urine flow during blockage of the catheter in the urethra, carried out using a pear pump valveless system.

The pear pump consists of an elastic element made in the form of a cavity, which on both sides has wire channels with expanding ellipsoidal cavities. A way to eliminate clogging of the catheter hole is that one of the ellipsoidal cavities (for example, the front) is tightly compressed by fingers (clip or clothespin), blocking the passage hole for urine (fluid). Then, without letting go of the anterior ellipsoid cavity, the elastic force element (pear) is strongly compressed, pushing urine into the bag. Without releasing the elastic element (pear), the front ellipsoid cavity is released, but the back ellipsoid cavity is immediately compressed. After that, the elastic element (pear) is released, freeing it from the muscular strength of a person or other mechanism of action. The back ellipsoidal cavity is held until the elastic element (pear) takes its original shape, straightened and filled with liquid. After that, the process of outflow of urine is restored. The flushing process is carried out by the patient himself or, in extreme cases, by medical personnel. By manipulating the overlap of ellipsoidal cavities, you can also clean the tip of the catheter with small holes, as well as rinse the bladder or other organ with saline (medicine).

Figure 1 shows a catheter 1, a pear pump 2, a bag 3 (for collecting urine) with a drain pipe 4.

Figure 2 shows the pear pump 2, made of an elastic element, the neck 5, the front ellipsoid cavity 6 in the elastic body 7 with a conical tip 8 for immersing it in the mouth of the catheter 1 (Fig.1), the rear ellipsoid cavity 9 (Fig. 2) in an elastic case 10 with a conical receiver 11 for immersing the conical tip of the tube 4 into it (Fig. 1).

Figure 3 shows a section (section. A-A, figure 2) of the front elliptical cavity 6 in the elastic body 7 in an uncompressed form.

Figure 4 shows the front or rear ellipsoidal cavity 7 or 10, compressed with your fingers (clip or clothespin).

Figure 5 shows a section (section. BB-BB, figure 2), the rear ellipsoid cavity 9 in the elastic body 10 in an uncompressed form and the neck 12.

In the process of recovery of the patient, if necessary, restore the urine flow when the catheter hole is blocked with slag, the tip of the tube 4 (Fig. 1) is removed from the mouth of the catheter 1 and a pear pump is inserted between them (Fig. 2). The ellipsoidal cavity 6 (FIG. 3) closes when the elastic body 7 is pressed, as a result of which the opening 13 is hermetically closed. This moment is depicted in FIG. 4. Then the pear pump 2 (figure 2) is compressed so that the liquid is squeezed out into the bag 3 (figure 1). The elastic body 7 (FIG. 3) is released, while the ellipsoid cavity is straightened, opening the hole 13, and the walls of the cavity 9 (FIGS. 5 and 2), on the contrary, are compressed by the housing 10. This position is again shown in FIG. 4. The pear pump is released, and it creates a vacuum in the hole 13, drawing the slagged material and the torn away tissue into the cavity of the pear pump 2. The process is repeated, expelling the slagged liquid into the bag.

To flush the internal organs with drugs, the tube 4 (Fig. 1) is removed from the cone 11 (Fig. 2) with a compressed back ellipsoid cavity 9 and a hose with saline solution is connected, driving it into the bladder and back, washing the internal organ.

In the cavities 6 and 9 of the pear pump, valves can be set, but this is undesirable, since some of the functions of the device will be reduced.

The device will allow the patient to service himself, without resorting to the help of busy medical personnel. An increase in the number of independent organ washes will lead to the fastest recovery of the patient.

Claims (1)

A device for restoring the flow of urine or fluid when the catheter is blocked, containing an elastic element made in the form of a cavity, characterized in that on both sides of the cavity there are wire channels with expanding ellipsoidal cavities, while the elastic element and ellipsoid cavities are made with the possibility of compression.
