Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a clinical hydrops draw-out device that uses, including cylinder 1, syringe needle 3 and piston disc 9, be equipped with anti-reflux mechanism 2 between cylinder 1 and the syringe needle 3, anti-reflux mechanism 2 is including fixed casing 201, through fixed casing 201 intercommunication between 1 surplus syringe needle 3 of cylinder, the inner chamber of fixed casing 201 is equipped with the flexure strip 202 of arc form, and one side that flexure strip 202 is close to syringe needle 3 is equipped with hemispherical rubber's protruding 203, flexure strip 202 can give protruding 203 an elasticity, make protruding 203 and fixed casing 201's space carry out the block, can effectually prevent the hydrops backward flow, the curved surface of flexure strip 202 indent is located one side near cylinder 1, the vertical end both sides of cylinder 1 are equipped with rubber ball 6 respectively and receiving flask 4 sees, receiving flask 4 passes through the bottom of screw thread closure connection at cylinder 1.

Specifically, as shown in fig. 4, the elastic piece 202 is elastically connected to the inner surface wall of the vertical end of the fixed housing 201 through a spring 204, and the spring 204 gives the elastic piece 202 an elastic force in the vertical direction, so that the elastic piece 202 is deformed under force.
