As the further improvement of the utility model, the mistake cannot restrain one's anger liquid one-way conduction valve and Y connection one
Connection, micro particle filtering film and middle interconnecting piece integrally connected.
As the further improvement of the utility model, aperture≤5 μm of the micro particle filtering film.
Compared with prior art, the disposable apparatus for intravenous injection transfusion system of the utility model has the beneficial effect that:
(1) it crosses cannot restrain one's anger liquid one-way conduction valve to be opened by the liquid-driving injected, when venous transfusion needs to be injected intravenously
When, do not have to split perfusion tube and injection needle, without governor is closed, energy intravenous (IV) drug reduces because fractionation causes
Pollution risk.
(2) aperture≤5 μm of micro particle filtering film 73, micro particle filtering film 73 can by 4 μm or more of particle such as rubber stopper clast,
Glass chip filters out, and avoids enter into human body and causes harm to the human body.
(3) structure is simple, convenient for operation, is suitable for hospital clinical and operates.
