Description
Technical field
This utility model relates to a kind of single use locking type transfusion device, belongs to medical instruments field.
Background technology
At present, the filter in China's disposable infusion set of prior art is socket form, easily gets loose, cause leakage when being connected with venous duct interface; Patient walks about as left the bed when infusing simultaneously, and both easily pull, and cause accident.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, and provide a kind of single use locking type transfusion device, it can not only solve the problem of filter and the leakage of venous duct interface, can also avoid the phenomenon that both come off.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of single use locking type transfusion device, it comprises perforator, dropping funnel, transfusion catheter, actuator, filter, venous duct interface, venous duct and intravenous needle, the end of perforator is connected with the liquid feeding end of dropping funnel, the liquid outlet of dropping funnel is connected with the inlet of transfusion catheter, the liquid outlet of transfusion catheter is connected with the liquid feeding end of filter, venous duct interface is arranged on the inlet of venous duct, the liquid outlet of venous duct is connected with intravenous needle, described actuator is connected in transfusion catheter, the position that filter is connected with venous duct interface is provided with locking-type screw thread, venous duct interface is provided with dop on corresponding position, the liquid outlet of filter is coordinated and the stressed joint of venous duct interface lock by this locking-type screw thread and dop.
After have employed technique scheme, the connection of filter and venous duct interface is connected by locking-type screw thread and dop, and make both connect more firm, avoid the problem of leakage, it also avoid the hidden danger come off simultaneously, therefore product is safely and efficiently.
