Description

Technical Field

[0001] The utility model relates to the technical field of blood sampling, in particular to a blood sampling auxiliary device. Background Art

[0002] When medical staff draw blood from patients, the patients first put their arms on the blood collection pad. Then the medical staff use a cuff to tie a slipknot around the patient's arm and ask the patient to clench his fist to make the vein bulge. After that, the medical staff punctures the vein to draw blood, then loosens the cuff to complete the blood drawing.

[0003] For example, the blood sampling auxiliary device with patent number CN218899464U includes a seat, a compression device and a forearm support plate arranged on the seat, an inflation control component and a deflation control component arranged in the seat, wherein the compression device includes a connecting seat connected to the seat, a rear arm sleeve obliquely arranged on the connecting seat, and an air bag ring surrounding the inner wall of the rear arm sleeve. The above document still has deficiencies. When in use, the air bag ring is inflated through the inflation control component to make the patient's vein bulge, without the need to manually tie a compression belt, which brings convenience to medical staff. Not only that, the inflation control component is also used to inflate the air bag ring. The inflated airbag ring can also support the patient's posterior arm, bringing comfort to the patient; the posterior arm sleeve is tilted, which can make the patient's arm in a tilted state, making it convenient for medical staff to puncture. However, when the auxiliary device in the above document is in use, the height of the device is fixed. When different patients have their arms at different heights during blood collection, it is inconvenient to adjust the height of the device during blood collection. At the same time, when blood collection is performed, the angle of the support plate is fixed, and the patient needs to adjust the angle of the arm by himself. The operation is more troublesome and it is inconvenient to adjust the angle of the support plate. Utility Model Content
