RU69753U1 - DEVICE FOR THE INTRODUCTION OF LIQUID MEDICINES INTO THE UTERUS WHEN TREATING COWS WITH CHRONIC AND HIDDEN ENDOMETRITIS - Google Patents

Abstract

This utility model relates to the field of instruments and accessories for veterinary obstetrics and gynecology and can be used in the treatment and preventive measures in animal husbandry. The purpose of the proposed utility model is the introduction of liquid preparations into the uterine cavity of cows in several directions, without applying efforts to overcome negative pressure, which will significantly accelerate and facilitate the administration process. To achieve this goal, we propose using a catheter to wash embryos in cows for intrauterine administration of liquid preparations. The device will consist of a stylet (1), a rubber catheter body (2) with lateral holes (3), an air can (4), an expanded part of the catheter with a lock (5), and a rubber tube (6) for connecting to a 20- syringe 150 ml (7). The catheter for washing embryos in cows has three holes in the upper part, which allows the injected substance to flow in three directions and at a faster rate than was possible with only one hole. In addition, the presence of several holes in the catheter allows you to easily overcome the negative pressure of the uterus, which makes this method of intrauterine administration of liquid medicinal substances available to any specialist, and the use of a metal stylet provides a more convenient insertion of the catheter into the uterine cavity, eliminating excesses. Feasibility is expressed in the simplicity and ease of use of the model, strength, reliability, ease of disinfection and accessibility to any specialist.

Description

This utility model relates to the field of instruments and accessories for veterinary obstetrics and gynecology and can be used in the treatment and preventive measures in animal husbandry.

Currently, there are several devices for introducing liquid medicinal substances into the uterine cavity of patients with endometritis of cows.

So, according to the data of G.V. Zvereva and S.P. Homin, 1976 (Gynecological diseases of cows / G.V. Zvereva, S.P. Homin / Kiev .: Harvest, 1976. - 126 p.), In the treatment of cows patients with endometritis, the uterus is washed with aqueous solutions of disinfectants, the Esmarch mug is used to administer them, followed by their removal from the uterine cavity using an irrigator (author V.A. Akatov). However, the solutions introduced into the uterine cavity must be completely removed, which is not always feasible and, as a consequence, can lead to a decrease in muscle tone and maceration of the uterine mucosa epithelium, preventing its self-cleaning. This method cannot be used to treat cows with chronic and latent endometritis, since it involves the introduction of a large volume of fluid into the uterine cavity, while in chronic endometritis it should not exceed 100 ml, and 20 ml with hidden.

Recommended by N.I. Polyantsev, M: 1986 (Practical Advice on Combating Barrels of Cows / N.I. Polyantsev./ M .: Rosselkhozizdat, 1986. - 150-151 p.), A device for artificial insemination of pigs (POS-5 ) cannot be used to introduce liquid medicinal substances into the uterus of cows with hidden endometritis due to incomplete aspiration of fluid from the vial.

A Janet syringe with an attached rubber tube, which is inserted into the cow’s vagina with a plastic gloved hand, cannot be used because of the increased risk of contamination of the animal’s genital tract.

Typically, intrauterine administration of liquid medicinal substances is carried out using a polystyrene insemination pipette and a syringe attached to it by the rectocervical method. (Metrites of cows. / I.N. Zyubin. - M .: Agropromizdat, 1988. - 50 p.) This method allows you to enter the required volume of the substance into the uterine cavity of the animal, but the fluid flow through the central opening of the pipette is only in one direction and it is necessary make great efforts when introduced to overcome negative pressure in the uterus. In addition, the seed pipette has a polystyrene, non-solid base, and its introduction is less convenient due to the occurrence of kinks.

In veterinary practice, when carrying out transplantation of embryos in cows for non-surgical extraction of embryos, a catheter for washing the embryos is used, consisting of a rubber body of the catheter (1) with three lateral openings (2), an air balloon (3), an air injection channel (4), an inflatable balloon (5), an expanded part of the catheter with a lock (6) and a stylet (7). (Fig. 1) (Instructions for transplantation of cattle embryos. - M .: 1987. - 94 p.)

The purpose of the proposed utility model is the introduction of liquid preparations into the uterine cavity of cows in several directions, without applying efforts to overcome negative pressure, which will significantly accelerate and facilitate the administration process.

To achieve this goal, we propose using a catheter to wash embryos in cows for intrauterine administration of liquid preparations. The device will consist of a stylet (1), a rubber catheter body (2) with lateral openings (3), a can

for air (4), the expanded part of the catheter with a lock (5) and a rubber tube (6) for connection with a syringe with a volume of 20-150 ml (7). (fig. 2)

The catheter for washing embryos in cows has three holes in the upper part, which allows the injected substance to flow in three directions and at a faster rate than was possible with only one hole. In addition, the presence of several holes in the catheter allows you to easily overcome the negative pressure of the uterus, which makes this method of intrauterine administration of liquid medicinal substances available to any specialist, and the use of a metal stylet provides a more convenient insertion of the catheter into the uterine cavity, eliminating excesses.

In practice, the purpose of this utility model is implemented as follows:

Before carrying out medical procedures, the area of the external genitalia of the animal is washed with warm water and get wet.

Of the sterile parts (the catheter and rubber tubes are boiling, the metal stylet of the catheter is neutralized with 70 ° alcohol), the proposed device for introducing liquid drugs into the uterus in the treatment of cows with chronic and hidden endometritis is assembled in working condition.

The left arm is inserted into the rectum and freed from feces. A catheter along with a stylet along the upper edge of the vagina is inserted into the genital tract of the cow and guided into the external opening of the cervix, the neck is grasped with the palm of the left hand and, turning it left and right, it is pulled onto the catheter. As soon as it enters the uterine cavity by 6-8 cm, the stylet is completely removed from the catheter, a sterile syringe with the required volume of the drug substance is connected through a rubber tube, and the drug is introduced into the uterus, after which the catheter is removed.

The parts used are subjected to pre-sterilization and sterilization.

Feasibility is expressed in the simplicity and ease of use of the model, strength, reliability, ease of disinfection and accessibility to any specialist.

The use of the proposed device for the introduction of liquid drugs into the uterus in the treatment of cows with chronic and hidden endometritis can be carried out on livestock farms, in maternity wards, as well as in other livestock buildings, where there is a milking herd of cattle.

Claims (1)

A device for introducing liquid drugs into the uterus in the treatment of cows with chronic and latent endometritis, consisting of a metal stylet, a catheter for flushing embryos from cows, connected using a rubber tube with a syringe with a volume of 20-150 ml.
