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.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of convenient aspirator of cirrhotic ascites, including The left side wall downside of liquid storing barrel 1 and suction tube 8, liquid storing barrel 1 is bolted with leakage fluid dram 2, and is equipped on the pipeline of leakage fluid dram 2 manually Valve, the antetheca of liquid storing barrel 1 are longitudinally provided with liquid level window 3, and the right side wall of liquid storing barrel 1 is fixedly connected with clamping frame by screw 4, the top left side of liquid storing barrel 1 is bolted with air pressure adjustment mouth 5, and the top right side of liquid storing barrel 1 is bolted with inlet 6, inlet 6 Right side is socketed with perfusion tube 7, and the left side wall upper end of suction tube 8 is connected with the liquid outlet connector 11 being connected with perfusion tube 7, suction tube 8 inner cavity is embedded with piston head 10, and the bottom of piston head 10 is plugged with push rod 9, and the top right side of suction tube 8 is connected with feed liquor and connects First 12, the upper end of liquid inlet joint 12 is socketed with syringe needle 13, is mounted on check valve on liquid inlet joint 12 and the pipeline of inlet 6 14。

Wherein, the bottom of liquid storing barrel 1 is socketed with counter weight base, and counter weight base is cast iron type counter weight base, so that liquid storage Bucket 1 is stablized, and air pressure adjustment mouth 5 is hollow pipeline formula air pressure adjustment mouth, and the inner cavity of air pressure adjustment mouth 5 is embedded with dust-proof cotton block, Play dust-proof effect, perfusion tube 7 is rubber hose or bellows, have the function of stretching, can adjustment length, check valve 14 include left shell half 141 and right half-shell 142, is bonded between left shell half 141 and right half-shell 142 by bonding agent, left shell half 141 Inner cavity upper right side is connected with grip block 143, and grip block 143 and 142 bracket of right half-shell are clamped with rubber slab 144.

The liquid flow direction of check valve 14 in liquid inlet joint 12 is to be flowed from syringe needle 13 to suction tube 8, on inlet 6 Check valve 14 liquid flow direction be flowed from perfusion tube 7 into liquid storing barrel 1, flow direction be right half-shell 142 in liquid Body is flowed into left shell half 141, and rubber slab 144 turns down to the left under the action of fluid pressure, to open, when reverse flow, Rubber slab 144 will not be turned down in the case where the inner wall of right half-shell 142 stops, to play unidirectionally controlled effect.

Syringe needle 13: being inserted in the place for needing to extract ascites by working principle, by lower pulling-pushing rod 9, is driven and is lived by push rod 9 Chock plug 10 pulls down, and the inner cavity top of suction tube 8 generates negative pressure, so that syringe needle 13 draws ascites, due to unidirectional on inlet 6 The effect of valve 14, so that gas flowing is not generated between inlet 6 and suction tube 8, thus by the inner cavity of ascites sucking suction tube 8 Upside after sucking, above push rod 9 and drives piston head 10 above to push away, and above pushing away for piston head 10 generates pressure to the ascites on top, by In the effect of check valve 14 in liquid inlet joint 12, so that ascites can only be entered in liquid storing barrel 1 by perfusion tube 7 and inlet 6 Chamber avoids removing emission problem in suction process, pass through so that suction tube 8 can persistently draw ascites Liquid level window 3 can observe the liquid measure for concentrating on the ascites of 1 inner cavity of liquid storing barrel, after reaching a certain amount of i.e. by the discharge of leakage fluid dram 2 It can.

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.
