[0002] Hemodialysis is a common means of clinical treatment for uremia. Before performing hemodialysis on uremia patients, the blood pipeline should be pre-flushed with cleaning fluid to ensure that the hemodialysis pipeline reaches a normal medical state without impurities and bubbles. The waste liquid generated by the pre-flushing of the hemodialysis pipeline with cleaning fluid is collected and processed in a waste liquid collection bag. During the production process, each waste liquid collection bag needs to be tested for air tightness to avoid leakage during use.

[0003] The waste liquid bag detection system in the existing technology is large in size, complex in structure, and has limited applicable scenarios.

[0004] Therefore, a detection system is needed that has a simple structure, a small size, and is easy to connect to production lines of different specifications for use. Summary of the Invention

[0006] To achieve the above-mentioned purpose, the technical solution adopted in this scheme is: a waste liquid bag gas inspection system, including a gas storage device and a raising frame fixed on the base plate, the gap between the raising frame and the base plate is used to place the waste liquid bag, and the gas storage device is connected to the pressing component and the detection tube.

[0007] Furthermore, the pressing assembly is fixed on the heightening frame, and includes a cylinder connected to a pressing plate on the bracket.

[0008] Furthermore, the cylinder drives the pressing plate to move up and down in the through hole at the top of the elevated frame, and the pressing plate is used to press the air outlet of the waste liquid bag.

[0009] Furthermore, the gas storage device is connected to the gas circuit control center and fixed on one side of the base plate, and the gas storage device is connected to the detection tube.

[0010] Furthermore, the other end of the detection tube includes an air outlet needle, which is inserted into and seals the feed port of the waste liquid bag.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1:

[0023] A waste liquid bag gas detection system, as shown in the figure, a gas storage device 2 and a raising frame 3 are fixed on the bottom plate 1, the gas storage device 2 is connected to a pressing component 4 and a detection tube 5, and the pressing component 4 is fixed on the raising frame 3.

[0024] The gas storage device 2 provides a power source for the cylinder 42 of the pressing component 4 and is connected to the gas circuit control center and fixed on one side of the base plate 1.

[0025] The space between the raising frame 3 and the bottom plate 1 is used for placing waste liquid bags. The top of the raising frame 3 includes a through hole 31 for passing the pressing component 4 , and the pressing component 4 is fixed beside the through hole 31 .

[0026] The pressing assembly 4 and the bracket 41 are connected to the cylinder 42. The bottom of the cylinder 42 is connected and drives the pressing plate 43 to move up and down in the through hole 31. The pressing plate 43 is used to press the air outlet of the waste liquid bag to prevent the air outlet from leaking during the detection process and affecting the detection effect.

[0027] The cylinder 42 in this embodiment is a dual-axis cylinder 42, which can be directly purchased from Wuxi Smart Automation Technology Co., Ltd. It is an existing technology well known to those skilled in the art and will not be described in detail here.

[0028] One end of the detection tube 5 is connected to the gas storage device 2, and the other end includes an air outlet needle 51. The air outlet needle 51 is inserted into and seals the feed port of the waste liquid bag. The gas enters the waste liquid bag from the air outlet needle 51, and the sealing of the waste liquid bag is judged by observing the data changes of the gas circuit control center.

[0029] Further explanation based on its usage mechanism:

[0030] Insert the air outlet needle 51 into the feed port of the waste liquid bag and place it in the gap between the raising frame 3 and the bottom plate 1. The cylinder 42 drives the pressing plate 43 to descend toward the waste liquid bag until it presses the air outlet of the waste liquid bag.

[0031] The air outlet needle 51 delivers air to the waste liquid bag and determines the sealing condition of the waste liquid bag by observing the data changes of the air path control center.

[0032] In summary, the waste liquid bag gas inspection system provided in this application has a simple structure, a small size, and is convenient for connection to production lines of different specifications for use.
