Description

Technical Field

[0001] The utility model specifically relates to the technical field of blood drawing assistance, and in particular to a blood drawing assistance device. Background Art

[0002] Venous blood sampling is a method of extracting a certain amount of venous blood through a needle for examination, mostly using superficial veins located on the body surface. In the prior art, before blood collection, the patient is required to sit in front of a blood collection table, place his forearm on the blood collection table with his palm facing up, and place a pillow under his elbow, and clench his hand to expose the puncture site.

[0003] However, when medical staff draw blood from patients in the inpatient department, in order to ensure the smooth progress of blood drawing, the patient needs to lie on the bed, and then place a pillow on the patient's bed, and then place the patient's elbow on the pillow for blood drawing. However, it is inconvenient for pregnant nurses to squat when drawing blood at the bedside. At the same time, for nurses on night shifts, a large amount of bedside blood drawing work will cause the nurses to bend or squat all the time, which is easy to cause waist injuries in the long run. Therefore, a blood drawing auxiliary device is urgently needed to solve the above problems. Utility Model Content

[0010] Furthermore, fixing bolts are provided on one side outer wall of the first movable frame and the second movable frame, and the first movable frame and the second movable frame are fixedly connected to a connecting plate via the fixing bolts.

[0011] Furthermore, the bottom of the connecting plate is fixedly connected to a rotating seat, and the inner walls on both sides of the rotating seat are rotatably connected to rollers.

[0012] Furthermore, both ends of the rotating shaft are provided with thread grooves, and the rotating shaft is threadedly connected with a fixing nut through the thread grooves.

[0013] Furthermore, a clamping rod is fixedly connected to an outer wall of one side of the second movable frame, and a clamping groove is provided on one side of the first movable frame.

[0014] Furthermore, a spring is fixedly connected to an inner wall of one side of the slot, and the springs are evenly distributed inside the slot. An end of the spring away from the inner wall of one side of the slot is fixedly connected to a stop block, and the stop block is tightly pressed against an outer wall of one side of the clamping rod.

[0015] Furthermore, a connecting column is fixedly connected to the top outer wall of the first movable frame and the second movable frame, and a hanging ring is fixedly connected to the top of the connecting column.
