Automatic-exhaust transfusion device

Abstract

The invention discloses an automatic-exhaust transfusion device comprising a bottle-connecting pin, a Murphy's dropper, a hose, a speed governor and a filter. The automatic-exhaust transfusion device is characterized in that a water outlet pipe at the lower part of the Murphy's dropper extends into the cavity of the Murphy's dropper, the nozzle of the water outlet pipe is 2 centimeters higher than the bottom of the Murphy's dropper, the pipe wall of the water outlet pipe at the junction of the water outlet pipe and the Murphy's dropper is provided with a small round hole, and the diameter of the small round hole is obviously less than that of the water outlet pipe. In the transfusion and exhaust process of a transfusion pipe, liquid firstly accumulates in the Murphy's dropper to reach the nozzle level of the water outlet pipe, and then flows into the water outlet pipe to execute the downward exhaust and transfusion subsequently, thereby reducing the operation step that nursing personnel must firstly invert the Murphy's dropper in the transfusion and exhaust process, and relieving the workload of the clinic nursing personnel.

Description

technical field [0001] The invention belongs to a disposable infusion set, in particular to an infusion set capable of automatic exhaust and liquid injection. Background technique [0002] In clinical work, before the infusion starts, it is often necessary to turn the Murphy dropper upside down first, and then turn the Murphy dropper over immediately after the liquid has infused the Murphy dropper to a certain extent, so as to continue to infuse the infusion. The process of injecting liquid into the water pipe to exhaust air, turning the Murphy's dropper upside down and then turning it over is cumbersome, which brings inconvenience to clinical work. Contents of the invention [0003] The object of the present invention is to provide a kind of infusion set that can exhaust automatically aiming at the defects of the above-mentioned prior art. [0004] Its technical solution is as follows: an automatic exhaust infusion set, which includes a bottle-connecting plug, a Murphy's...
