Repeated insertion and extraction avoiding blood transfusion bag

Abstract

The invention discloses a blood transfusion bag which avoids repeated insertion, which comprises a connecting tube and a puncture needle, wherein, one end of the connecting tube is plugged and connected with the puncture needle, and the other end is further provided with a three-way tube, and the three-way tube is provided with a 3 Murphy droppers, the Murphy dropper is provided with a trachea tube and a bottle insertion needle, and the trachea tube, the bottle insertion needle, the Murphy dropper, the tee pipe and the connecting pipe are integrally formed during manufacture. A control valve is further arranged on the three-way pipe, and the control valve is connected in rotation with the three-way pipe. A regulating valve and a filter are arranged on the connecting pipe. The filter and the connecting pipe are integrally formed during manufacture, and the regulating valve and the connecting pipe rotation connection. The needle length is 3‑6 cm. The invention is simple in structure, easy to use, effectively avoids repeated plugging and unplugging, reduces the probability of pollution, and reduces the labor intensity of medical staff.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a blood transfusion bag which avoids repeated insertion. Background technique: [0002] At present, when clinically transfusing blood to patients, the conventional blood transfusion bags that avoid repeated insertion are used. The current blood transfusion bags that avoid repeated insertion include bottle insertion needles, puncture needles and Murphy droppers. The bottle needle is inserted and connected to the blood bag, the puncture needle penetrates into the patient's blood vessel, and the blood bag and the human body form a passage through the Murphy dropper. This conventional blood transfusion bag avoids repeated insertion. Due to different blood sources, plasma with the same blood type may not have the same RH factor. Therefore, after hanging a bag of plasma, it is necessary to rinse the Murphy dropper with saline. After the tube is flushed, the next bag of plasma is connected. For ...

AI Technical Summary

Problems solved by technology

For patients with severe trauma and large blood loss, it is troublesome to hang the blood bag repeatedly and rinse repeatedly, which affects the patient's blood transfusion rescue, and the repeated insertion and withdrawal of the insertion needle has a high chance of contamination and the labor intensity of the medical staff is also high.
