Double-cavity drop funnel blood transfusion device

Abstract

The invention discloses a double-cavity chamber transfusion set, which includes a spike, a soft cannula, a chamber, a transfusion tube and a vena transfusion needle, the vena transfusion needle is connected with the output end of the chamber by the transfusion tube, the chamber includes a chamber bottle, a dropper arranged in the chamber bottle and a filter, the dropper is positioned at the middle part of the chamber bottle and is closely connected with the inner wall of the chamber bottle and partitions the inner cavity of the chamber bottle into an upper cavity and a lower cavity serving as a press cavity, the filter is arranged in the upper cavity of the chamber bottle. Because of the adoption of the technique proposal of the invention, the peripheral wall of the lower cavity of the chamber bottle can be pinched come-and-go during the blood transfusion process for ensuring that the filter net will not be blocked and the traffic will not be affected, then the pressure in the lower cavity of the chamber bottle can be pushed upward, blood coagulation matters and impurities piled on the filter will be scattered in the upper cavity of the chamber bottle, so the filter is unblocked, thus the dripping amount and blood cleanness of the dropper can be ensured, and the blood coagulation matters and impurities will not flow into the human body.

Description

technical field [0001] The invention relates to a medical device, in particular to a double-cavity drip funnel blood transfusion set. Background technique [0002] Existing blood transfusion set (see Fig. 1) comprises insertion needle 1, hose 2, drip funnel 3, transfusion vessel 4, regulator 5 and intravenous infusion needle 6 etc., and intravenous infusion needle 6 passes transfusion vessel 4 and drip funnel 3 The dripper 3 is composed of a dripper pot 31, a dripper 32 and a filter 33 arranged in the dripper pot 31, and the dripper pot 31 is generally made of PVC material by injection molding or blister and extrusion process , has a certain degree of elasticity; the dropper 32 is located at the upper end of the dropper pot 31, and the flow rate of the dropper 32 is 20 drops per 1 milliliter of blood; the filter 33 is located at the bottom of the dripper pot, and it stops impurities in the blood from being filtered On the device 33 and can clean the blood. However, coagula...

Problems solved by technology

However, coagulation and impurities in the blood will block the filter 33 during the blood transfusion, affect the blood transfusion speed and even block the blood filtration. The usual clinical practice is to pinch the peripheral wall of the drip bucket 31 back and forth, Inflate to increase its pressure to ensure the smooth completion of the blood transfusion process

However, due to the structural characteristics of the existing dripping funnel 3, this method is likely to cause coagulation and impurities to flow into the human body together with the blood, affecting the quality of blood transfusion
