Description

TECHNICAL FIELD

[0002] In the medical field, liquid discharge devices are commonly used in postoperative drainage, chest drainage, abdominal cavity drainage and other scenarios. The core function of the liquid discharge device is to remove abnormal accumulated fluids such as blood, pus, tissue fluid or gas in the body cavity through negative pressure suction or gravity, to maintain the stability of the physiological environment, prevent infection, promote wound healing and restore organ function.

[0003] According to the application number: CN202211059880.0, the liquid discharge device for surgical nursing includes a hospital bed, a anti-loosening assembly is arranged on the upper end face of the hospital bed, an anti-toppling assembly is arranged on one side of the hospital bed, an antibacterial liquid injection assembly is arranged on the hospital bed, a indwelling tube is arranged on the anti-loosening assembly, a rubber plug is fixedly connected to one end of the indwelling tube, in the moving body moving to the left, the moving body will be clamped in the pipe on the right side of the sleeve body after moving a distance against the ball, and cannot continue to move to the left. At this time, the indwelling tube and the sleeve body cannot continue to separate, and the first drainage tube fixed on the sleeve body can continue to receive the discharged liquid from the indwelling tube. This design can effectively prevent the indwelling tube on the patient from slipping between the connection of the drainage device and the sleeve body due to the patient's turning over and other actions, and prevent the exposed indwelling tube after slipping from entering the patient's body with weak resistance, causing infection.

[0004] However, in the prior art, when different parts of the patient need to be drained, the liquid discharge device usually needs to be equipped with multiple specifications of suction heads to adapt to different anatomical structures and drainage requirements. Although most of the suction heads currently use buckle type connection, which has a certain installation and disassembly convenience, since each suction head is usually packaged independently, if the first selected suction head does not match the target part in actual operation, the appropriate model needs to be selected and replaced, which causes the previously removed suction head to be unable to be used again, resulting in waste of medical consumables and affecting the economic cost of clinical use. In addition, in an emergency or high-intensity working environment, repeatedly searching for and replacing the suction head can also affect the operation efficiency, and even delay the treatment opportunity.
