Description

Technical Field

[0001] The utility model belongs to the technical field of leak detection in a dialysis dry powder barrel, and in particular relates to a leak detection device for a dialysis dry powder barrel. Background Art

[0002] Dialysis is a separation and purification technology that separates small molecules from biomacromolecules based on the principle that small molecules diffuse into water through a semipermeable membrane. Dialysis therapy is a treatment method that allows components in body fluids to be excreted from the body through a semipermeable membrane. It can generally be divided into hemodialysis and peritoneal dialysis.

[0003] In this regard, China applied for patent number: CN 210741786 U, which discloses a hemodialysis dry powder barrel leak detection device, including a lower end sealing seat, an upper end sealing seat, a lifting device and a control device. The upper end sealing seat is connected to the lower end sealing seat through the lifting device, and a plurality of first grooves matching the lower end of the dry powder barrel are arranged on the lower end sealing seat. The upper end sealing seat includes a plurality of sealing end covers, a bracket and an air inlet pipe. A second groove matching the upper end cover of the dry powder barrel is arranged on the lower end surface of the sealing end cover. The sealing end cover is connected with the air inlet pipe, and the upper end of the air inlet pipe is connected to the bracket, and the bracket is connected to the lower end sealing seat through the lifting device. The utility model detects the pressure inside the dry powder barrel by arranging a pressure sensor with an output. When the pressure inside the dry powder barrel is less than the pressure set in the PLC module, the pressure sensor with an output will send a signal to the PLC module, and the PLC module will send a signal to the buzzer and the alarm light, so that the alarm light on the upper part of the corresponding dry powder barrel becomes bright and the buzzer alarms.

[0004] However, in actual use, this structure can only be used to perform air tightness detection operations during the production process of dialysis dry powder barrels. After the dialysis dry powder barrels are actually filled with powder, efficient leak detection auxiliary operations cannot be performed on them. Some dialysis dry powder barrels will still have leakage problems during use. At the same time, the equipment cannot perform efficient loading and unloading operations on dialysis dry powder barrels and cannot meet daily use needs. Therefore, it has become an urgent problem to be solved to improve and perfect the above-mentioned problems. Utility Model Content

At the same time, the equipment cannot perform efficient loading and unloading operations of dialysis dry powder barrels and cannot meet daily use needs.

[0012] Preferably, a powder discharge grid is provided on the back of the detection frame, and a powder collecting cover is movably connected to the back of the detection frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1.

In actual use, the staff first loads the powder into the dialysis dry powder barrel and seals it, and then puts the dialysis dry powder barrel as a whole into the detection frame, and connects the upper and lower ends to the vibration seats of the upper and lower supports respectively, and then seals the side of the detection frame by pulling out the side frame, and at this time starts the vibration motor in the center of the upper support to make the powder leak. It cooperates with the positioning rubber ring and vibration spring inside the upper support and the lower support to drive the two groups of vibration seats and the dialysis dry powder barrel inside the detection frame to perform rapid up and down vibration operations, and at the same time starts the powder detection units at the upper and lower ends of the upper and lower supports. After the dialysis dry powder barrel is shaken, due to its poor air tightness, the flying powder can enter the inside of the powder collection cover from the powder discharge grille of the detection frame, and then the upper and lower groups of powder detection units perform synchronous leak detection operations, and the powder collection cover can be quickly disassembled and assembled from the back of the detection frame, which is convenient for daily internal cleaning and processing, thereby improving the equipment's leak detection accuracy for dialysis dry powder barrels, reflecting the practicality of the equipment design.

In daily use, the staff can put the dialysis dry powder barrel that needs to be loaded and unloaded into the limit seats at the upper and lower ends of the pull-out side frame for limit positioning. At this time, the upper and lower ends of the dialysis dry powder barrel can be butted against the damping connector inside the limit seat. Then, the dialysis dry powder barrel can be quickly sent into the interior of the detection frame as a whole through the pull-out handle. At this time, the docking slide groove of the damping connector can be limitedly slidably docked with the docking slides of the upper and lower two groups of vibration seats.
