Abstract

The invention discloses an automatic vent type transfusion set. The automatic vent type transfusion set comprises an upper transfusion pipe, a drop funnel, a lower transfusion pipe, and a regulating switch; a liquid inlet and a liquid outlet of the drop funnel are respectively communicated with a lower end of the upper transfusion pipe and an upper end of the lower transfusion pipe; the regulating switch is arranged on the lower transfusion pipe; a contact pin is connected with an upper end of the upper transfusion pipe; a transfusion needle is connected with a lower end of the lower transfusion pipe; the automatic vent type transfusion set of the invention also comprises a reducer; the reducer is arranged between the liquid outlet of the drop funnel and the lower transfusion pipe; and during transfusion, bubbles entering the reducer are extruded and broken into smaller bubbles at the position of the smallest inner diameter of the reducer, and the smaller bubbles overcome the self-gravitation action to float upwards so as to be discharged, so that the aim of automatically venting gas is fulfilled. The automatic vent type transfusion set has the advantages of simple structure, convenient processing, and capability of achieving effects of venting the gas in real time and smoothly transfusing liquid medicine.

Description

technical field [0001] The invention relates to a medical device, in particular to an automatic exhaust type transfusion blood transfusion set. Background technique [0002] The infusion set is mainly used to deliver medicinal liquid or blood to the patient. Its structure mainly includes an insertion needle, an upper infusion tube, a drip funnel, a lower infusion tube, an adjustment switch and an injection needle; The apertures of the connection between the bucket and the lower infusion tube are consistent with the aperture of the infusion tube, so that when the infusion set with the above structure is used to infuse the patient, when the adjustment switch is turned on, the liquid may enter the infusion set. Bubbles will be generated, and the generated bubbles will flow with the flow of the liquid. When the bubbles pass through the above-mentioned connection, because there is no change in the pipe diameter, the bubbles will smoothly flow through the place and enter the lower...
