Arm decompression type radial artery compression and hemostatic device

Abstract

The invention provides an arm decompression type radial artery compression and hemostatic device which comprises a decompression unit and a hemostatic unit. The decompression unit comprises a decompression supporting plate and fixing belts. The decompression supporting plate is in a strip shape, the upper surface of the decompression supporting plate is matched with an anatomical structure of the back of a forearm of an arm in shape, the decompression supporting plate is downwards bent to be in an arc shape in the direction of long edges, and the fixing belts are located on the same long side edge of the decompression supporting plate. The hemostatic unit comprises a pressing plate, a connection belt, a nut, a threaded rod and a compression pad. The hemostatic unit is arranged on the decompression supporting plate through the pressing plate and the connection belt in a sleeving mode. The portions, located on the two sides of the threaded rod, of the pressing plate form two side wings. The lower surface of one of the side wings is provided with a flexible fixing pad for assisting in supporting the threaded rod, and the bottom face of the compression pad is provided with hemostatic dressing; the hemostatic device is good in hemostatic effect, firm to fix and capable of scattering the compression force borne by the hemostatic portion, lowering compression on veins by the hemostatic device and guaranteeing smooth blood circulation.

Description

technical field [0001] The invention relates to a medical hemostat, in particular to a disposable compression hemostat acting on the radial artery, which belongs to the technical field of medical instruments. Background technique [0002] Interventional surgery is already a routine treatment method in medical departments such as cardiology and neurology. The advantage of interventional surgery is that doctors can enter the patient's body for treatment without using general anesthetics or surgery. Under normal circumstances, interventional diagnosis and treatment operations, especially interventional operations in the Department of Cardiology, are performed through the patient's radial artery access. The interventional operation of the radial artery access has fewer complications, and the patient is bedridden for a short time to restrict activities. Low cost and other advantages, but like other arterial puncture operations, complete hemostasis of arteries after intervention i...

Problems solved by technology

At present, hemostasis at the radial artery puncture point is mainly through artificial hemostasis or mechanical pressure equipment, and artificial hemostasis is through manual pressure by medical staff or applying bandage pressure to stop bleeding. This method consumes a lot of physical strength and time for medical staff; the existing mechanical pressure The equipment is generally inflated or pushed and pressurized through airbags or knobs, which can reduce the physical exertion of medical staff and improve the efficiency of hemostasis. However, there are two significant problems with this type of equipment. One is that the hemostasis effect is poor, and the success rate of hemostasis is not as high as artificial hemostasis. There are many cases of bleeding; the second is that the venous return is blocked due to the large pressure on the arm, which leads to swelling and purple of the hand and arm, which increases the discomfort and panic of the patient
