A hemostatic rescue device for clinical use in cardiology with buffer protection function

Abstract

The invention discloses a clinical hemostasis rescue device for cardiology department with buffer protection function, comprising a circular-shaped base ring and a base, an inner groove is opened on the inner wall of the base ring, and the shaft of the inner groove is connected with the axis of the base ring. The center is located on the same straight line, the inner wall of the inner groove is sealed and glued with two circles of liquid sacs at equal distances, the shortest distance between the two circles of the liquid sacs is 1cm, and the base ring side wall corresponding to each of the liquid sacs is provided with a A square side cavity, a square box is fixedly connected in the side cavity, and a piston plate is sealed and slidably connected inside the square box. The advantage is that: the electrorheological fluid in the liquid sac changes from the original liquid state to a solid-like structure when the device is energized. At this time, the liquid sac cannot be deformed and the whole hemostatic state is maintained, and the continuous operation of the medical staff is not required. The sac is soft in the initial stage, and there will be no brute force to cause injury to the patient.

Description

technical field [0001] The invention relates to the technical field of cardiology, in particular to a hemostatic rescue device for clinical cardiology with a buffer protection function. Background technique [0002] Department of Cardiology, that is, Department of Cardiovascular Medicine, is a clinical department set up by major internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular and vascular diseases. Interventional therapy is a new discipline that has developed rapidly in recent years and integrates imaging diagnosis and clinical treatment. At present, it has become the three pillar clinical disciplines alongside traditional internal medicine and surgery. The incisions of interventional surgery are generally in the wrist and thigh blood vessels of the human body. When an accident occurs during the operation and the blood vessel is bleeding acutely, the bleeding must be stopped as soon as possible. The existing clinical...

Problems solved by technology

The incisions of interventional surgery are generally in the wrist and thigh blood vessels of the human body. When an accident occurs during the operation and the blood vessel is bleeding acutely, the bleeding must be stopped as soon as possible. The existing clinical hemostasis rescue device has a complicated structure and high production cost.

[0003] After searching, the Chinese patent with the publication number CN108420488A discloses a hemostatic rescue device for clinical cardiology with buffer protection function. In this patent, the buffer column drives the moving plate to move downward, and the moving plate squeezes the hydraulic oil. Slow upward movement through the through hole reduces the movement speed of the moving plate, effectively improving the buffer function of the hand or leg; the first bevel gear drives the threaded rod to rotate, and since the lifting column cannot rotate, the lifting column plays the role of the threaded rod The downward movement drives the upper pressure plate to move downward, compresses the bleeding site, and quickly stops the bleeding, effectively improving the hemostatic effect. Although it has a certain hemostatic effect, it also has a great negative effect on the limbs during the hemostasis process. : Long-term compression can lead to necrosis of the nerves of the extremities, and at the same time, no blood flow in the extremities for a long time can also cause tissue necrosis, and it is also extremely inconvenient when a certain position of the extremities needs to be moved
