Description

Technical Field

[0001] The present invention relates to the field of medical technology, in particular to a device for extracorporeal blood circulation treatment. Background Art

[0002] Extracorporeal circulation and blood processing equipment utilizes a series of specialized artificial devices to drain returning venous blood outside the body. After artificial processing for energy replenishment, gas exchange, temperature regulation, and blood purification, it is then returned to the body's arteries. The dialyzer consists of hollow fibers, a housing, a sealing layer, and end caps. Thin, elongated hollow fibers made of dialysis membrane are bundled together and placed within a transparent cylindrical housing. Both sides are sealed with a non-toxic medical polyurethane adhesive and secured to the housing. The hollow fibers open outside the sealing layer and are screwed shut with dome-shaped caps at their outer ends, forming a blood chamber. The top of the cap is open for connecting blood tubing. The space formed by the dialyzer housing and the sealing layers on both sides is divided by the dialysis membrane into a blood chamber and a dialysate chamber, each with an inlet and outlet. During use, the blood chamber outlet and inlet are connected to the venous and arterial blood circuits, respectively. The dialysate flows in and out in the opposite direction of the blood.

[0003] During extracorporeal blood circulation treatment, the blood is generally dialyzed using a dialyzer. Before the dialyzer is used, the blood pump needs to be started to use physiological saline to discharge the gas in the blood chamber of the dialyzer. In order to completely discharge the gas in the semipermeable membrane, the medical staff needs to shake the dialyzer during the exhaust. After the dialysis is completed, in order to reduce the amount of residual blood in the dialyzer and reduce the degree of anemia in the dialysis patient, the medical staff also needs to rub the dialyzer back and forth in the palm of their hands, using the principle of vibration to make the blood cells in the dialyzer float up and be washed back into the body by physiological saline. When shaking and rubbing the dialyzer to vibrate the blood cells, the medical staff needs to hold the dialyzer in their hands and operate it manually, which is not only difficult to form a standardized operating angle and speed, but also easy to cause the dialyzer to slip out of the hand.

[0034] Working principle: During installation, the opening electromagnet 507 is energized, and after the opening electromagnet 507 is energized, it attracts the armature block 506, so that the pull slider 504 pulls the push-pull connecting rod 511, and the push-pull connecting rod 511 pulls the shaft cylinder 509 to open the clamping arms 407, and then the dialyzer is placed between the two clamping arms 407, and the opening electromagnet 507 is de-energized, and the clamping spring 508 rebounds and pushes the pull slider 504 to return to its original position. When the pull slider 504 is returned to its original position, the shaft cylinder 509 is pulled by the push-pull connecting rod 511 to close the clamping arms 407, and then the locking electromagnet 413 is energized, and after the locking electromagnet 413 is energized, it attracts the locking armature bar 414, so that the two clamping arms 407 fix the dialyzer, and then the four input and output hoses of the dialyzer are clamped into the four clamping grooves 206 along the tube installation seam 207, thereby completing the installation; During exhaust, after physiological saline is introduced into the dialyzer, the swing motor 307 and the vibration motor 302 are started. The vibration motor 302 generates vibrations that drive the dialyzer to vibrate, and the swing motor 307 generates periodic forward and reverse rotations. When the swing motor 307 is forward and reversed, it drives the driving bevel gear 308 to rotate forward and reverse periodically through the worm gear reducer 306. The driving bevel gear 308 drives the swing shaft 303 to rotate forward and reverse periodically through the driven bevel gear 305, thereby causing the dialyzer clamping and mounting mechanism, the opening and closing drive mechanism, and the dialyzer to swing, thereby shaking out the air remaining in the dialyzer and the semipermeable membrane, and then discharging it with the physiological saline. When blood is returned, physiological saline is introduced into the dialyzer and the vibration motor 302 is started. The vibration motor 302 generates vibrations to drive the dialyzer to vibrate, thereby shaking out the remaining air in the dialyzer, and then the air flows back into the patient's body along with the physiological saline.
