Hemostasis tool used after artery blood sampling after EICU operation

Abstract

The invention relates to the technical field of hemostasis after artery blood sampling, and discloses a hemostasis tool used after artery blood sampling after EICU operation. The hemostasis tool comprises a shell; a screw rod is movably connected to the interior of the shell; the surface of the screw rod is movably connected with an extrusion wheel; a spring rod is movably connected into the extrusion wheel; the surfaces of extrusion teeth are movably connected with a connecting cover; the surface of the connecting cover is movably connected with a wire ring; traction ropes are movably arranged on the surface of the wire ring; one end, away from the wire ring, of each traction rope is movably connected with a wire tightening column. In using process, the spring rod is driven to move, so that a puncture hole moves; fingers are moved for multiple times until the numb feeling of the hand is achieved, so that assisting effect is provided for medical personnel to find a puncturing blood sampling part; after the feeling is achieved, the index finger and the ring finger are separated, and then the index finger and the ring finger move, the two traction ropes cannot drive a differential shaft to move on the surface of a wire combining rod due to the fact that the winding angles and the winding speeds are different, so that the puncturing part is fixed.

Description

technical field [0001] The invention relates to the technical field of hemostasis after arterial blood sampling, in particular to a hemostatic appliance used after arterial blood sampling after EICU operation. Background technique [0002] EICU is the Emergency Intensive Care Unit. The Emergency Intensive Care Unit works 24 hours a year and can treat critically ill patients at any time. After the critically ill patients are treated, arterial blood sampling is required to judge the hypoxia in the blood and the presence of carbon dioxide. Retention; and blood collection sites generally choose superficial, easy-to-reach arteries with many side branches on the body surface, such as radial artery, brachial artery, femoral artery, etc., combined with the American Clinical Laboratory Standards Institute (CLSI) arterial blood collection site selection criteria, the first choice Radial artery. [0003] The radial artery is located in the wrist, superficial and easy to puncture. The...

Problems solved by technology

The patient has a high degree of cooperation and can observe the puncture site at any time. The commonly used arterial blood collection technology is relatively mature, but the method of hemostasis after blood collection is still manual pressure. Since the radial artery is one of the large arteries of the human body, the blood flow is relatively large. It needs to be pressed for a period of time to ensure that the wound coagulates, and during this period of artificial pressing, it will feel boring, and the slight movement of the human body will affect the strength of the pressing, and the change of the pressing force will affect the speed of platelet movement, which may cause wounds In addition, when performing puncture and blood collection, there is no corresponding auxiliary equipment to help medical staff determine the site to be punctured, which in turn affects the process and speed of blood collection. Therefore, a hemostasis after arterial blood collection after EICU Utensils come into being
