Left ventricle indwelling hard sheath for connecting artificial blood vessel

An inner cavity of a sheath tube and an inner cavity of a large head portion are communicated, an air bag is arranged on the outer side face of the front end portion of the sheath tube, a medical felt tube sleeve is sleeved on the sheath tube, a section of light tube is reserved between the medical felt tube sleeve and the air bag, a section of external threads is arranged on the rear end portion of the sheath tube close to the medical felt tube sleeve, and the external threads are communicated with the air bag. A medical felt gasket and a nut are sequentially arranged on the external thread, a plurality of narrow kerfs which are through front and back are formed in the peripheral side of the nut, a plurality of winding hooks are arranged on the rear side face of the nut, the winding hooks are circularly arranged to form a wire spool, the inner diameter of a base circle where the winding hooks are located is larger than the outer diameter of a base circle of the large head part, and a containing cavity is formed in the large head part. A blood blocking valve is arranged on a base of the containing cavity, an internal thread port is formed in the outer end of the large head portion, and the blood blocking valve blocks the internal thread port. When an artificial heart device is implanted, the heart of a patient does not need to be stopped and cardiac muscle does not need to be cut off, surgical operation is simplified, the surgical process is shortened, and the influence on the heart function of the patient is relieved.

Radial artery compressor control method and related devices

The application provides a radial artery compressor control method and related equipment, which can be used in the field of image processing technology; the method comprises the following steps: acquiring a first laser blood image of a hand region of a target object collected by an image acquisition component; determining a target speckle contrast according to the pixel intensity of a pixel point in the first laser blood image, and determining the current blood flow rate of the hand region according to the target speckle contrast; in the case that the current blood flow rate indicates that the radial artery has an occlusion risk, controlling the ulnar artery balloon to deflate, and determining a target pressure according to the highest pressure pulse wave amplitude of the target object in the deflation process of the ulnar artery balloon; controlling the ulnar artery balloon to inflate until the pressure applied by the ulnar artery balloon to the ulnar artery reaches a blockage pressure, and controlling the radial artery balloon to inflate or deflate until the pressure applied by the radial artery balloon to the radial artery reaches the target pressure. In the application, the blood flow of the radial artery is ensured to be unobstructed to avoid radial artery occlusion.

High-efficiency dialysate circulation filter device for medical dialysis equipment

PendingCN122272939ACirculatory resistance decreasesavoid the risk of complicationsDialysis fluidMechanical engineering
This invention discloses a high-efficiency dialysate circulation filtration device for medical dialysis equipment, relating to the field of dialysis filtration technology. It includes a cylindrical body and an external connection. A hollow fiber membrane is installed inside the cylindrical body, dividing the inner part of the body into a cylindrical space and an annular space. Annular connecting blocks are fixedly installed at both ends of the hollow fiber membrane. An internal groove is formed in the annular connecting block away from the blood input end. An adjustment part is provided on the annular connecting block with the internal groove. A connecting part is provided in the external connection. A limiting groove is formed on the inner wall of the cylindrical body, and an arc groove is formed within the limiting groove. A sealing part for closing the cylindrical body is provided on the external connection. A cleaning mechanism for cleaning the hollow fiber membrane is provided on the cylindrical body. By incorporating the adjustment part, this device can adaptively adjust the pressure within the cylindrical space, thereby reducing the circulation resistance within the cylindrical space, ensuring stable blood flow during dialysis, and avoiding the risk of complications for dialysis patients.
