Cow rectum air exhaust device

Abstract

The invention relates to a cow rectum air exhaust device, comprising an elastic air bag, a check valve and an air exhaust pipe, wherein the elastic air bag is provided with at least an air inlet type check valve and an air outlet type check valve; the air inlet type check valve is provided with an air exhaust pipe; and the specified position of the middle section in the exhaust pipe is provided with an expanding balloon which is communicated with an air conveying pipe. The cow rectum air exhaust device utilizes the principle that the elastic air bag and the check valve are matched to realize continuous air exhausting, is provided with a controllable expanding balloon at the position of the cow rectum in which the exhaust pipe is approximately located, thus guaranteeing that the air exhaust and the closing of anus opening are carried out simultaneously, preventing the outside air from entering into the rectum and ensuring the success of air exhaust of the rectum. The cow rectum exhaustdevice has convenient operation, ensures high testing efficiency and good effect and has higher promotion value in the same field.

Description

cow rectal aspirator 1. Technical field: The invention relates to a technology for extracting air from the rectum of a cow, in particular to a device for extracting air from the rectum of a cow. 2. Background technology: Cattle rectal inflation is a relatively common phenomenon in the field of animal husbandry when it is used for cattle rectal examination, embryo transfer, in vitro fertilization and other operations. When performing a rectal examination of a cow, because the arm is moving in the rectum of the cow, the cow is very uncomfortable to perform the crossbow, and the rectum is inflated, which makes the rectal wall very hard, and the uterus and ovaries cannot be accurately felt, and the rectal examination cannot be performed. If the rectum drains by itself It takes a long time to wait, and it will delay a lot of time. Sometimes the follow-up work cannot be completed, resulting in a lot of waste. Especially after the anesthesia was administered before the operatio...

AI Technical Summary

Problems solved by technology

Therefore, when inflating the rectum of the cow, the air should be extracted in time to facilitate further inspection. However, there is no effective pumping device for inflating the rectum of the cow.

Some relevant technicians have improved the pedal-type air cylinder for inflating the balloon and made it into a simple air pumping device after reverse connection. The suction tube forms a channel at the rectal opening, and the air outside the body will enter the rectum again, resulting in failure of suction
