Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of anorectal surgical exhaust apparatus, including pumping Room 1, the right side wall of aspirating chamber 1 are provided with end cap 2, and the middle part of end cap 2 offers through slot, and transverse splicing has push rod 3 in through slot, The right end of push rod 3 is bolted with push plate 4, and the outer wall of push rod 3 is socketed with support spring 5, and the both ends of support spring 5 are respectively supported at end On the right side wall of lid 2 and the left side wall of push plate 4, the inner cavity of aspirating chamber 1 is provided with pumping piston 6, pumping piston 6 and push rod 3 Left end is spirally connected, and the top left side of aspirating chamber 1 is provided with gas outlet, and escape pipe 7 is bolted on gas outlet, is passed through on the upside of gas outlet Screw is connected with the first valve plate 8, and the left side wall of aspirating chamber 1 offers air inlet, and the inner cavity left side wall of aspirating chamber 1 is connected by screw It is connected to the second valve plate 9, the second valve plate 9 covers on air inlet, is socketed with bellows 10, ripple on the left side air inlet of aspirating chamber 1 The left end of pipe 10 is connect with the right end of control valve 11, and the left end of control valve 11 is connected with exhaust tube 12, a left side for exhaust tube 12 End surfaces grinding process is avoided to human injury, is provided on the pipeline of exhaust tube 12 and is flow backwards ball storehouse 13, the outer wall of exhaust tube 12 On be socketed with support plate 14.

Wherein, the two sides up and down of end cap 2, which are provided with, pulls plate, the first valve plate 8 and the second valve plate 9 include rubber slab and The support bone plate being bonded on rubber slab side wall, the tapered shape in the left end of exhaust tube 12, the diameter for flowing backwards ball storehouse 13 are greater than pumping The diameter of pipe 12.

The effect of rubber slab and support bone plate has the function of limiting gas unidirectional flowing, the first valve plate 8 and the second valve plate 9 On support rib board diameter be respectively greater than the diameter of air inlet, gas outlet, and the side of rubber slab by screw and air inlet, go out The edge of port connects, and pushes rubber slab together with support bone plate open when air pressure is larger；

Exhaust tube 12 is inserted in the place for needing to be evacuated, ball storehouse 13 is flow backwards and enters in vivo, support plate 14 supports in vitro, subtracts Lack the entrance of bacterium and avoids more gases entrance under the influence of air pressure in vivo, opening controlling valve door 11, so that exhaust tube It is connected between 12 and bellows 10；

Exhaust: index finger and middle finger are pulled in the pulling on plate of about 2 two sides of end cap respectively, and thumb press push plate 4, push plate 4 pushes away Dynamic push rod 3 moves to left, and support spring 5 is compressed, and push rod 3 pushes pumping piston 6 to move to left, and the air pressure in aspirating chamber 1 increases, compared with atmosphere The first valve plate 8 is pushed open upwards under the action of pressure, the gas of 1 inner cavity of aspirating chamber is discharged by escape pipe 7, is set on escape pipe 7 Sterilizing unit (such as device of high-temperature steam sterilization or ultraviolet-sterilization) is set, and the support bone plate on the second valve plate 9 is in air pressure The rubber slab of the second valve plate 9 is tightly attached on the right side wall of air inlet under effect, so that gas will not be by air inlet to ripple It is moved in pipe 10；

Air-breathing: support spring 5 is compressed in above-mentioned steps of exhausting, sheds thumb to the pressure of push plate 4, in support spring 5 Under the action of elastic force, push plate 4 drives push rod 3 and pumping piston 6 to move to right, and the inner cavity of aspirating chamber 1 generates negative pressure, in the effect of negative pressure Lower second valve plate 9 is pushed open to the right, and under the action of the support bone plate on the first valve plate 8, the rubber slab of the first valve plate 8 only pastes It is attached on gas outlet, under the action of negative pressure, intracorporal gas enters the inner cavity of aspirating chamber 1 by exhaust tube 12, bellows 10；

By being vented above, air-breathing the step of carry out taking out intracorporal gas, detect intracorporal gas content for convenience, can Increase air pressure detector on exhaust tube 12, detect intracorporal air pressure, for controlling the operation of exhaust, inhalation step.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
