Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a device for testing the air tightness of a pulse flushing medical device pump body. Background Art
[0002] The pulse flushing pump uses pulsating water flow under a certain pressure to flush the wound tissue. The pulse water flow oscillates the bacteria and foreign matter in the wound and separates them from the tissue by bouncing, achieving the purpose of thorough debridement. The air tightness of the pulse flushing pump body must be tested during production, but the existing air tightness testing equipment is cumbersome to operate and requires high-precision testing equipment, which is costly. Summary of the invention

[0004] To achieve the above object, the present invention provides the following technical solution: a pulse flushing medical device pump body air tightness test device, which includes a base, a shell is fixedly arranged on the base, a display screen is arranged on the front side of the shell, a pressure reducing valve is installed on one side of the shell, and the pressure reducing valve is connected to an air source; A cylinder is fixedly mounted on the base in front of the housing, a test fixture is fixedly mounted on the left side of the cylinder, a stopper is fixedly arranged on the left side of the test fixture, and a sealing plug is mounted on the output end of the cylinder.
[0005] Preferably, an inflation valve and a barometer are installed in the shell, and a controller is electrically connected to the back of the display screen, and the controller is electrically connected to the inflation valve and the barometer.
[0006] Preferably, the sealing plug is made of rubber or silicone.
[0007] Preferably, the material of the test fixture is engineering plastic, and the test fixture and the stopper are fixed on the base by bolts.
[0008] Preferably, control buttons for start, stop and emergency stop are provided on the front side of the shell.
[0009] Beneficial effects: Compared with the prior art, the beneficial effects of the present invention are: the air tightness testing equipment can automatically perform the inflation and pressure maintenance test processes, and can display the test results in real time, and the operation is simple and convenient; the coordination of the test tooling and the cylinder simplifies the test equipment and reduces the cost of the equipment.

[0013] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0014] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0015] Example Please refer to the drawings of the specification. In the embodiment of the present invention, a pulse flushing medical device pump body air tightness test device includes a base 1, a shell 2 is fixedly arranged on the base 1, a display screen 3 is arranged on the front side of the shell 2, an inflation valve and a barometer are installed in the shell 2, a controller is electrically connected to the back of the display screen 3, and the controller is electrically connected to the inflation valve and the barometer, a pressure reducing valve 4 is installed on one side of the shell 2, and the pressure reducing valve 4 is externally connected to an air source, and a start, stop, and emergency stop control buttons are arranged on the front side of the shell 2; A cylinder 5 is fixedly installed on the base 1 in front of the housing 2, a test fixture 6 is fixedly installed on the left side of the cylinder 5, a stopper 7 is fixedly provided on the left side of the test fixture 6, the test fixture 6 is made of engineering plastic, the test fixture 6 and the stopper 7 are fixedly installed on the base 1 by bolts, and a sealing plug 11 made of rubber or silicone material is installed on the output end of the cylinder 5.
[0016] Usage process: When in use, the inflation port 9 of the pump body 8 is connected to the test equipment through an air pipe, and the pump body 8 is placed on the test fixture 6 so that the sealing port 10 corresponds to the sealing plug 11, and then the cylinder 5 is controlled to extend so that the sealing plug 11 seals the sealing port 10, and then the pump body 8 is inflated by the test equipment. After the inflation is completed, the inflation valve in the test equipment is closed, and the pressure is delayed to maintain; if the air pressure does not drop to the set value within the delay time, it means that the air tightness is qualified, otherwise it is a leak, and the test result is displayed on the display screen 3; when the delay time is up, the piston of the cylinder 5 retracts.
[0017] During the above process, the air tightness testing equipment can automatically perform the inflation and pressure maintenance tests, and can display the test results in real time, and the operation is simple and convenient; the coordination between the test tooling and the cylinder simplifies the testing equipment and reduces the cost of the equipment; the present application has a simple structure, strong practicality, and simple operation, and is worthy of promotion.
[0018] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
