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.
