The utility model discloses a filter cover plate structure, include: the lower cover body of constitution has the accommodating space and the upper cover body of cooperation and connection with lower cover body, the accommodating space is used for constituting the liquid medicine storage processing area, including upper end processing area and lower end processing area, the first support of bearing diaphragm is provided in the upper end processing area, the second support of bearing diaphragm is provided in the lower end processing area, the height of first support is higher than the height of second support, to make liquid medicine storage processing area form the hierarchical distribution on space. Through above -mentioned mode, the utility model discloses a filter cover plate structure can provide stable and reliable support for filter membrane and breathable membrane, effectively avoid the occurrence of filter membrane and breathable membrane deformation, can smoothly and efficiently filter liquid medicine, exhaust gas, avoid air embolism, ensure infusion safety.

This invention provides a hysteroscopic irrigation pressurization device, including a pressurizer and an air detector. The pressurizer includes a pressurizing component, a fixing component, a mounting bracket, and a processor. The pressurizing component is connected to a drive motor. The pressurizing component is used to accelerate the flow of liquid through the connecting tube connected to the infusion tubing. The fixing component is used to stabilize and fix the connectors at both ends of the connecting tube. The mounting bracket is used to fix the air detector. The processor includes a signal receiving module and a control module. The air detector includes a detection part and a clamping part, which can be clamped onto the infusion tubing to detect the inside of the infusion tubing. The detection part is equipped with a detection module and a signal transmission module, which transmits the detection results of the detection module to the signal receiving module of the pressurizer through the signal transmission module, realizing the start / stop operation function of the drive motor, and avoiding uterine air embolism caused by continuing to pressurize when the infusion bag and infusion tubing are empty.

The application discloses a hemodialysis circulating pipeline, which comprises an arterial pipe and an arterial pot installed on one side of the arterial pipe, the outer wall of the arterial pipe is uniformly connected with a plurality of auxiliary pipes, the top end of the auxiliary pipe is provided with a sealing mechanism, and a buffer pot is installed on the top of the auxiliary pipe for reducing instantaneous impact during liquid supplementing, and the application relates to the technical field of dialysis pipeline. The hemodialysis circulating pipeline has the advantages that the joint anti-loosening performance is improved compared with the traditional conical surface friction joint through the triple anti-loosening mechanism of the axial thread fastening of the external connection fixing mechanism, the end surface elastic sealing and the anti-skid point static friction, the joint effectively resists the low-frequency vibration of a dialysis machine and the continuous pulling of a patient, and the double structure of the elastic clasp axial locking and the steering protrusion circumferential locking of the steering limiting mechanism is matched, the joint anti-pulling-off force is further improved, the serious safety hazards such as blood leakage and joint collapse are fundamentally eliminated, and the risks of patient blood loss and air embolism are avoided.
