Abstract

Disclosed is an anti-reflux medical three-way device for infusion drug adding. The device comprises a three-way valve body, two ends of the three-way valve body are used as liquid inlets, and an interface formed in the middle of the three-way valve is an liquid outlet; a check mechanism is installed in the tree-way valve body. The check mechanism comprises non-return elastic pipes and a connectingpiece, the connecting piece is slidably and cooperatively installed in the middle of the three-way valve body, two ends of the connecting piece are connected with one ends of the non-return elastic pipes, and the other ends of the non-return elastic pipes are sealed and abutted against the inner end of a connecting seat; clearances are reserved between the non-return elastic pipes and the inner wall of the three-way valve body. The device has the advantages that each liquid inlet can be connected with an injector, when medicinal liquid is injected by the injector, an infusion path is automatically opened by pressing the sealed end of the related non-return elastic pipe, and no opening and closing operation is needed to perform to prevent mistaken operation; the phenomenons of seepage, overflow and reflux do not occur when the device is used, and safety of injecting and sucking performed in injection or in the process of injection can be well ensured.

Description

technical field [0001] The invention relates to a three-way device for anti-reflux infusion plus medicine, which belongs to the field of medical equipment. Background technique [0002] The one-way check effect of the existing three-way infusion device is poor, and a switch is required to perform the check. It is difficult to operate the switch when connecting a hose during use, and leakage, overflow, and backflow occur. There are safety hazards in the process. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a three-way device for anti-reflux infusion plus medicine. [0004] The technical solution of the present invention is: a three-way device for anti-backflow transfusion and medicine, which is characterized in that it includes a three-way valve body, and the two ends of the three-way valve body are used as liquid inlets, and the liquid inlets are equipped with There is a curved connecting seat used t...
