Description

one

The invention relates to veterinary medicine, namely to veterinary urology.

A known urinary catheter for cows, consisting of two movable tubes and a cricoid ring 1).

However, its introduction into the bladder is associated with a strong stretch of the urethral opening, which leads to severe pain.

Known catheter, made of metal tubes with a slightly curved tip 2.

This catheter is easier to introduce, but the introduction procedure itself and the subsequent manipulation of the instrument are very painful for the animals due to the rigidity of the instrument.

The aim of the invention is to prevent trauma to the urethral area, as well as the convenience of orienting the front of the instrument during urological manipulation.

The goal is achieved by the fact that the tip is provided with a spiral-shaped process with a ball-shaped thickening at the end, and the tube is made elastic.

In addition, the tube at the end opposite to the tip is provided with a cannula with a stopper with a spherical thickening at its end located in a plane passing through the axis of the catheter and a spike-like thickening of the vitreous process.

The drawing shows a catheter incision.

It consists of a flexible tube 1. Tip 2 is equipped with a spiral shaped 3

10 with a ball-shaped thickening 4 at the end. The tip 2 at its base has a through channel 5 that communicates with the channel 6 of the catheter tube, 1. At the end of the tube 1, opposite the tip 2, there is a cannula 7 with a limiter 8 with a nasal thickening 9 at its end.

Claims (2)

A catheter is inserted in compliance with the aseptic and antiseptic rules after appropriate treatment of the area of the anus, lips, and the vaginal vestibule. The operator, with his index or middle finger, gropes for the urethral orifice and somewhat pushes his finger into his channel to the location of the entrance to the cavity of the diverticulum. With the other hand, a sterile, lubricated catheter is guided along the side of the finger with the vitokoobrazny surface of the tip of the catheter (the vitroculate deflection of the tip process seems to cover the lateral side of the finger), while the ball-shaped thickening 4 is in the upper position and is brought under the finger into the subgutical area. At the moment of withdrawal of the finger from the point of entry of the diverticulum, a widespread quench, 4 of catheter 1, is pressed into the urethra, the entrance to the diverticulum, and the catheter is advanced into the bladder cavity with a semi-rotary drilling movement. Testing the prototypes of the proposed catheter and their practical application in cattle that are unfavorable for neoplastic hematuria in the Vizhnitsky district of the Chernivtsi region, as well as in the research institute of agriculture and animal husbandry of the Western regions of the Ukrainian SSR showed that this catheter is convenient in operation and minimizes painful sensations in animals. Claims of the invention A urinary catheter made in the form of a tube with a tip with a through channel ending in its side wall, characterized in that, in order to prevent trauma to the urethral region, the tip is provided with a spiral shaped process with a ball-shaped thickening at the end, and the tube is made elastic. 2. A catheter according to claim 1, characterized in that, for the purpose of easy orientation of the front part of the instrument during urological manipulation, the tube at the end opposite to the tip is provided with a cannula with a restrictor with a nasal thickening at its end located in the plane passing through the axis of the catheter and the ball-shaped thickening of the vitcous process.
