Double-cavity drop funnel multi-way blood transfusion device

Abstract

The invention discloses a double-cavity chamber multi-channel transfusion set, which comprises a blood bag puncture needle, a brine bottle puncture needle, a blood transfusion soft cannula, a transfusion soft cannula, a three-way tube, a chamber, a soft cannula and a vena transfusion needle, the vena transfusion needle is connected with the output end of the chamber by the soft cannula, the three-way tube is positioned at the input end of the chamber, the two branch tubes thereof are respectively connected with the blood bag puncture needle and the brine bottle puncture needle through the blood transfusion soft cannula and the transfusion soft cannula that are nested with the clamp, 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 tightly 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. The technique proposal can ensure the dripping amount and blood cleanness of the dropper, so 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 multi-channel blood transfusion device. Background technique [0002] Existing medical multiplex blood transfusion set (see Fig. 1) comprises blood bag puncture needle 1, saline bottle puncture needle 4, blood transfusion hose 2, infusion hose 5, three regulators 3, 6, 10, a three-way pipe 7. A drip funnel 8, a flexible tube 9, and an intravenous infusion needle 11. The intravenous infusion needle 11 is connected to the output end of the drip funnel 8 through the flexible tube 9. The flexible tube 9 is covered with a regulator 10, which can be used to regulate blood transfusion or The speed of the infusion or the closing hose 9; the input end of the dripping funnel 8 is provided with a three-way pipe 7, and one of the other two branch pipes of the three-way pipe 7 passes through the blood transfusion hose 2 covered with the regulator 3 and the blood bag puncture nee...

Problems solved by technology

However, coagulation and impurities in the blood will block the filter 83 during the blood transfusion, affect the blood transfusion speed and even block the blood filtration. The usual practice in clinical practice is to pinch the surrounding wall of the drip bucket pot 81 back and forth to adjust the inner wall of the drip bucket pot 81. 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 8, under the action of extrusion pressure, this method will easily cause coagulation and impurities to flow into the human body together with the blood through the filter screen, affecting the quality of blood transfusion
