Foam rumen gas deflation puncture device

Abstract

The invention discloses a foaming ruminal tympany deflation puncture device and belongs to the technical field of veterinarian medical instruments. A puncture deflation needle is simultaneously provided with a deflation portion and a medicine injection portion, deflation can be performed while fermentation stopping and digestion promoting medicine or heart strengthening and stomach invigorating medicine is injected into rumen, moreover, the medicine injection portion can be unfolded in the ruminant rumen for rotary medicine injection, the rotating speed of the medicine injection portion can be manually controlled, mechanical beating and defoaming can be effectively performed, meanwhile, bubble chyme is prevented from blocking air vent holes, multi-point, large-range and omni-directional medicine injection into the rumen can be achieved, and effects of deflation, defoaming and medicine injection can be greatly improved. By means of the foaming ruminal tympany deflation puncture device, deflation rhythm can be controlled through an electromagnetic push-press box, air pressure in the rumen can be monitored through a pressure sensor, working intensity of operation staff is reduced, meanwhile, deflation rhythm and speed can be automatically controlled, and insertion depth of a needle body can be preset.

Description

technical field [0001] The invention relates to the technical field of veterinary medical instruments, in particular to a foam rumen gas deflation puncture device. Background technique [0002] Rumen gas is a digestive system disease unique to ruminants, which can be divided into acute rumen gas and chronic rumen gas according to the course of the disease. Since chronic rumen gas is not an independent disease, but a syndrome seen in the esophagus, forestomach, abomasum and intestinal chronic diseases, the principle of treatment is mainly to remove the primary disease, and symptomatic treatment is often ineffective, so , Rumen gas usually refers to acute rumen gas. [0003] Acute rumen gas is due to the decreased reactivity of the forestomach nerves, weakened contractility, and the fermentable feed that is eaten is rapidly fermented under the action of the flora in the rumen, resulting in a large amount of gas (foam), which causes a sharp rumen and reticulum. swelling.

AI Technical Summary

Problems solved by technology

First, for cattle with foamy gas disease, after the puncture needle punctures the rumen, due to the existence of a large number of air bubbles and the chyme on the air bubbles, the air release port will inevitably be blocked, and only a small amount of gas can be discharged intermittently. If the puncture needle is pulled out and cleaned again Puncture deflation, not only the degassing effect is still not ideal, but also increase the pain and infection risk of sick cattle; second, for rumen gas secondary to esophageal diseases such as esophageal obstruction, spasm and paralysis, and foam gas obstruction In the case of the cardia, anti-fermentation and anti-digestive drugs cannot be taken orally or orally, and can only be perfused by a rumen puncture trocar, which leads to the inability to perform puncture deflation and perfusion of anti-inflammatory drugs at the same time, which will delay the treatment of cattle with acute dysentery Time will also affect the treatment effect; third, even for simple gaseous rumen gas, generally sick cows will not cooperate with oral or intragastric administration of drugs, and still need to infuse anti-fermentation and digestion drugs through a puncture needle, while traditional puncture The needle has only one pinhole (i.e. air release hole) for perfusion. Not only is the perfusion speed slow, but also because it is a single-point perfusion, anti-fermentation and digestion drugs or stomach-enhancing drugs can only work in one place in the huge rumen (rumen gas When the rumen wall is tense, the automatic motility of smooth muscle is weakened, and the operation of rumen contents is sluggish), it cannot effectively play the role of anti-fermentation and digestion, and it is also unable to fully exert the effect of stomach-enhancing drugs; fourth, rumen gas, especially acute rumen gas During the puncture deflation, the deflation speed should be effectively controlled, and intermittent deflation should be carried out, so as to avoid the rapid decrease of abdominal pressure, the increase of chest negative pressure, and the rapid return of blood after rapid deflation, resulting in cerebral hypoxia, while the traditional puncture needle There is no device that can control intermittent deflation; fifth, the insertion depth of the puncture needle cannot be controlled

[0008] The device for treating rumen gas disclosed in the patent application number 201420327559.0 has a deflation part and a drug injection part, which solves the problem that the deflation and infusion of drugs cannot be carried out at the same time. Vent holes, for foamy rumen gas, are only gas that can get rid of multiple bubbles, and are still easily blocked by chyme in the bubbles, and the actual application effect is not good; in addition, the injection part is the same as the traditional puncture needle, Single-point injection can only be performed at the needle, and the rumen of ruminants (especially cattle) is huge in size, and the rumen movement is sluggish when gasping.
