Description

Technical Field

[0001] The utility model belongs to the technical field of blood sampling equipment, in particular to a blood sampling bracket used for a blood sampling chair in a blood station. Background Art

[0002] The blood station in the prior art is a blood collection and supply institution, which refers to a medical and health institution that collects, stores blood, and supplies blood to clinical or blood product production units. It is divided into blood stations, plasma collection stations, and blood banks. Blood stations generally have blood collection chairs because of the need to draw blood. The blood collection chairs are equipped with brackets for placing the arms of blood collectors.

[0003] A Chinese patent with publication number CN216455014U discloses a blood collection bracket for a blood collection chair in a blood station. The adjustment component includes an insertion rod rotatably installed at the bottom of a supporting plate, and also includes a plurality of insertion holes sequentially opened on the top of the supporting plate along the length direction. The supporting component includes a supporting plate rotatably installed on the top of the supporting plate along the vertical direction. An arc-shaped supporting plate arranged along its length direction is installed and inserted on the top of the supporting plate. A fixing belt arranged along its width direction is installed on one side of the arc-shaped supporting plate. A Velcro sub-strip and a Velcro mother-strip are respectively installed between the free end of the fixing belt and the other side of the arc-shaped supporting plate.

[0004] The above technical solution places the arm on the arc-shaped support plate, then inserts the rod into the corresponding socket, and then fixes the arm with Velcro to prevent the blood drawer from struggling due to pain and causing accidents. However, in actual use, since the arm is fixed on the arc-shaped support plate, if the blood drawer moves unconsciously after feeling pain during the needle prick, since the rod is inserted into the socket, the unconscious reaction may cause the load plate and the support plate to rotate, causing the rod to detach from the socket, resulting in the needle being inserted into the body, which will cause greater harm to the blood drawer and cause an accident.

[0005] In view of this, the present utility model is proposed. Utility Model Content
