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.
[0003] 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

Embodiment 1

[0025] Embodiment one: see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , a kind of cow rectal pumping device, comprises foot-operated elastic airbag 1, and elastic airbag 1 is equipped with at least one inlet type check valve 2 and an outlet type check valve 3, on the inlet type check valve 2 An air extraction pipe 4 is installed, and an inflation balloon 6 is provided at a specific position in the middle section of the air extraction pipe 4, and an air delivery pipe 5 is communicated with the inflation balloon. The air delivery pipe 5 is fixed on the inner wall of the air extraction pipe 4 .

[0026] The air delivery pipe 5 of the inflated balloon 6 is fixed on the exhaust pipe 4 and is provided with an inflation port 7 at the end. An inflation device is installed on the inflation port 7, and the inflation device usually adopts a syringe 8 so as to inflate or pump air in time. During operation, hold the suction tube 4 and extend the suction tube ...

Embodiment 2

[0028] Embodiment two: see figure 1 , Figure 5-1 , Image 6 , the numbers are the same as those in Embodiment 1, and the meanings are the same, and the same parts will not be repeated. The difference is that the air delivery pipe 5 is fixed on the inner side wall or the outer side wall of the exhaust pipe 4. A self-locking mechanism is provided on the gas delivery pipe. Since the self-locking mechanism has various forms and is a known technology, this embodiment only describes one of the structures, but does not exclude other self-locking forms.

[0029] The air delivery pipe 5 is an elastic pipe, and an elastic outer sleeve 51 is extended at both ends of the inflated balloon 6. The elastic outer sleeve 51 is set on the outside of the air extraction pipe 4, and a fixed stop 12 is added on the air extraction pipe 4. Since the elastic outer sleeve 51 51 or the elastic effect of the air pipe 5 ensure that the air-flow is only unblocked when there is high pressure, thereby ens...

Embodiment 3

[0030] Embodiment three: see figure 1 , Figure 7 , Figure 8 , the numbers are the same as those in Embodiment 1, and the meanings are the same, and the same parts will not be repeated. The difference is that the air delivery pipe 5 is fixed on the inner wall of the air extraction pipe 4 . The air delivery pipe 5 communicates with the inflated balloon through the inflation hole 11.

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 typecheck 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 exhaustand 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

1. Technical field: [0001] 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: [0002] 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 operation, the ...
