Description

Technical Field

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

[0002] Arterial blood sampling is a routine clinical blood sampling operation. By drawing arterial blood for blood gas analysis, it is a detection method that objectively reflects respiratory imbalance, hypoxia and carbon dioxide retention, helps diagnose respiratory and circulatory failure and guides treatment. It can provide a basis for diagnosis and treatment of cardiopulmonary diseases and various critically ill patients.

[0003] The Chinese patent with patent application number 202121194034.0 proposes a blood collection auxiliary frame for the CDC, including a support frame and a drawstring, a placement table is installed on the upper surface of the support frame, the upper surface of the placement table is an open structure, and a heating pad is installed on the upper surface of the placement table; an elastic pressure rod is installed inside the placement table, a pressure plate is installed on the telescopic end of the elastic pressure rod, a top pad is installed on the bottom of the pressure plate, and an airbag cushion is installed inside the top pad; a compressed air cushion is installed on the surface of the drawstring; an inflatable airbag and an air pump are installed inside the support frame. The beneficial effects are: the compressed air cushion can compress the bend of the arm to assist the insertion of the needle; the airbag cushion is continuously inflated and deflated by the air pump to assist the blood flow of the human body, without the need for continuous clenching and relaxation of the hands, and it is more comfortable to use.

[0004] However, after the improvement, the above patent still has the problem that when encountering elderly patients with limited mobility and needing to complete blood drawing in a wheelchair or tricycle, the height of the vehicle armrest is inconsistent with the position of the arm during blood drawing, which will change the body position of the person having blood drawn and cause accidental injury. In addition, when encountering pediatric patients, the size of the clamp cannot be adjusted according to the thickness of the patient's arm, which will make the patient easy to break free and affect the blood drawing.
