Description

Disposable breast, ascites aspirator

This utility model relates to a kind of disposable breast, ascites aspirator, is applicable to hospital clinical treatment hydrothorax and ascites.

Breast is worn, abdomen is worn the technology that art is medical treatment diagnosis upward commonly used, treatment hydrothorax and ascites.At present hospital's piercing method commonly used has two kinds, and a kind of is to be puncture needle with thicker ordinary syringe, and its operating process is loaded down with trivial details, and Extract is handled unhygienic; Another kind is being provided with the puncture needle of three-way cock, though operation is comparatively convenient, its cost is higher, the cleaning and sterilizing inconvenience, and Extract is handled also unhygienic.

The purpose of this utility model is design a kind of disposable breast, an ascites aspirator, by being provided with threeway bitubular permutator, reaches easy to use, non-toxic sanitary, purpose with low cost.

Disposable breast, ascites aspirator, include syringe, conduit, receipts liquid container and permutator, permutator is a threeway plastic cylinder, be inside and outside two, capping up and down, have one in the bottom of inner tube wall and lead to outside hand-hole, connect syringe needle by conduit, have one on the top of inner tube wall and lead to portalling between urceolus and the inner core, cover in the inner core lower seal and to be provided with one and to lead to outside access hole, connect syringe needle tube by conduit, have one in the bottom of outer tube wall and lead to outside portalling, receive liquid container by conduit.Be provided with thin slice in the hand-hole inboard of inner tube wall, the outside of portalling and constitute check valve.Its operation principle is: when syringe needle tube was pulled outwardly, negative pressure reached inner core, and the bottom hand-hole is opened, top go out bore closure, negative pressure reaches syringe needle, this moment, aspirator was in the aspirated liquid duty; Syringe needle tube take out full after, syringe needle tube is inwardly pushed away, malleation reaches inner core, the bottom go into bore closure, portalling of top opened, Extract is transported to the receipts liquid container.Cycling is to finishing overall process.
