Auxiliary device for blood drawing and transfusion

Abstract

The invention relates to an auxiliary device for blood drawing and transfusion. The auxiliary device for blood drawing and transfusion comprises a working table, an arm placing groove, an infrared sensor, a driving device, a traction device, a clamping device, a pressing sliding device, a working arm, a pulse pressing belt conveying and cutting device and a traction pressing device. The infrared sensor, the driving device, the traction device, the pressing sliding device, the driving device, the pulse pressing belt conveying and cutting device and the traction pressing device are respectivelycontrolled by a PLC controller which are accurate and reliabe during working, the rubber tube is replaced with a sanitary pressing belt, so that the health of the patient is further provided with safety guarantee. The auxiliary device for blood drawing and transfusion has the advantages of reasonable structural design, simple and convenient use, and is suitable for blood internal medicine and transfusion.

Description

technical field [0001] The invention relates to an auxiliary device for blood drawing and transfusion, which belongs to the technical field of medical instruments. Background technique [0002] At present, when doctors take blood samples for inspection and infusion, they usually put a pad on the table under the patient's arm, then use a rubber tube to tie the patient's arm tightly, and pat the blood-drawing part hard to expose the blood vessels. Then directly use the blood drawing needle to draw blood, or use the infusion needle for infusion, and use the rubber tube to tie the patient's arm tightly, which is time-consuming and laborious, and the repeated use of the rubber tube will also have a certain impact on the patient's health. If the banding time is too long, it will easily cause subcutaneous congestion of the patient, lead to numbness of the patient's arm, and increase the pain of the patient. Especially for organizational blood tests, due to the large number of peopl...

Then directly use the blood drawing needle to draw blood, or use the infusion needle for infusion, and use the rubber tube to tie the patient's arm tightly, which is time-consuming and laborious, and the repeated use of the rubber tube will also have a certain impact on the patient's health. If the banding time is too long, it will easily cause subcutaneous congestion of the patient, lead to numbness of the patient's arm, and increase the pain of the patient. Especially for organizational blood tests, due to the large number of people and the heavy workload, and the patient's arm is easy to move, repeated Tying rubber tubes will increase the burden on medical staff and cause unnecessary trouble
