Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, specifically to a device for testing the sealing performance and blockage of a dual-channel pipeline. Background Technology

[0002] Negative pressure therapy devices (a type of medical device) have dual-channel tubing, meaning they have one inlet and two outlets. During use, the sealing of this tubing is extremely important, as it not only affects the device's operation but can also delay the patient's treatment. Therefore, manufacturers have high requirements for testing the tubing's sealing and blockage resistance. However, due to manufacturing processes, the tubing may have both poor sealing and blockage issues, necessitating testing for both.

[0003] Current methods for testing pipeline sealing include:

[0004] 1. Connect the pipeline to the air pump, then apply soapy water to the surface of the pipeline and observe whether bubbles are generated to determine whether the pipeline is well sealed.

[0005] 2. Connect the pipeline to a three-way valve, connect one end to an air pump, and the other end to a pressure gauge. Observe whether the pressure value on the pressure gauge changes to determine whether the sealing is good or not.

[0006] Methods for detecting whether a pipeline is blocked include:

[0007] One end of the pipeline is connected to an air pump, and the other end is used to detect whether gas is flowing out.

[0008] However, for dual-channel pipelines, existing testing devices cannot simultaneously detect both sealing and blockage, requiring multiple devices to perform separate tests. Blockage detection can only identify complete blockages. Therefore, current methods for detecting sealing and blockage in dual-channel pipelines are inefficient, produce poor results, and require cumbersome tooling and fixtures, making disassembly and assembly inconvenient.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] This application provides a device for detecting the sealing and blockage of dual-channel pipelines, solving the problems of low detection efficiency, poor effect, and inability to complete the detection in one go in the current device for detecting the sealing and blockage of dual-channel pipelines.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Example:

[0042] like Figures 1-3 As shown, this utility model provides a device for detecting the sealing performance and blockage of a dual-channel pipeline. The device includes: an air pump connector 1, a first solenoid valve, an air pressure gauge 2, a pipeline inlet connector 3, a pipeline first outlet connector 4, a second solenoid valve, a pipeline second outlet connector 5, a third solenoid valve, and a controller.

[0043] The inlet connector 3 of the pipeline is connected in sequence to the pressure gauge 2, the first solenoid valve and the air pump connector 1.

[0044] The first outlet connector 4 of the pipeline is connected to the second solenoid valve at its end.

[0045] The second outlet connector 5 of the pipeline is connected to the third solenoid valve at its end.

[0046] The controller is electrically connected to the pressure gauge 2, the first solenoid valve, the second solenoid valve and the third solenoid valve respectively.

[0047] The end of the pipeline inlet connector 3 is used to connect the dual-channel pipeline to be tested with the end of the first outlet connector 4 and the end of the second outlet connector 5.

[0048] like Figure 1 , Figure 2 As shown, the device also includes: a housing 6;

[0049] The air pump connector 1, the first solenoid valve, the air pressure gauge 2, the pipeline inlet connector 3, the pipeline first outlet connector 4, the second solenoid valve, the pipeline second outlet connector 5, the third solenoid valve, and the controller are all installed inside the housing 6.

[0050] The head end of the air pump connector 1, the dial of the air pressure gauge 2, the end of the pipeline inlet connector 3, the head end of the first pipeline outlet connector 4, and the head end of the second pipeline outlet connector 5 all extend outside the outer casing 6.

[0051] like Figure 1 , Figure 2 As shown, the outer casing 6 is provided with: a power input port 7, a power switch 8, a start button 9, and an indicator light 10;

[0052] The power input port 7 is connected to a power source via a power cord to supply power to the first solenoid valve, the pressure gauge 2, the second solenoid valve, the third solenoid valve, and the controller.

[0053] The power switch 8 is used to control the power supply to be turned on and off.

[0054] The start button 9 is used to control the detection to be turned on and off;

[0055] The indicator light 10 is used to display the test results.

[0056] The device also includes: a buzzer;

[0057] The buzzer is used to sound an alarm when the test fails.

[0058] The pipeline inlet connector 3, the first pipeline outlet connector 4, and the second pipeline outlet connector 5 are all Luer connectors, which facilitates connection with the dual-channel pipeline to be tested.

[0059] The detection method of the device is as follows:

[0060] Connect the air pump to the air pump at the end of the air pump connector 1. Connect the dual-channel pipeline to be tested to the end of the pipeline inlet connector 3, the end of the first outlet connector 4, and the end of the second outlet connector 5 respectively. Turn on the power switch 8 to start the device initialization.

[0061] The controller opens the first solenoid valve and closes the second and third solenoid valves. After 1 second of inflation, the initial air pressure value X is obtained through the air pressure gauge 2. Then, the indicator light will flash several times to indicate that the system initialization is complete.

[0062] Press the start button 9. The controller controls the first and second solenoid valves to open and the third solenoid valve to close. After a period of time, it judges whether the deviation between the air pressure value displayed by the pressure gauge 2 and the initial air pressure value X is within the rated tolerance range (whether it is greater than 10%). If it is, it means that the corresponding channel is not blocked and the first indicator light 10 turns green. Otherwise, it means that the corresponding channel is blocked, the indicator light 10 turns red, the buzzer alarms, and the detection is interrupted.

[0063] If the detection is not interrupted, the controller controls the first and third solenoid valves to open and the second solenoid valve to close. After maintaining this for a period of time, it determines whether the deviation between the air pressure value displayed by the pressure gauge 2 and the initial air pressure value X is within the rated tolerance range (whether it is greater than 10%), in order to detect whether the other channel is blocked.

[0064] If the detection is not interrupted, the controller closes the first solenoid valve and opens the second and third solenoid valves to completely deflate the air passage. The controller then opens the first solenoid valve and closes the second and third solenoid valves, inflating for 1 second. Subsequently, the first solenoid valve is closed. Within 5 seconds, the controller checks whether the deviation between the air pressure in the air passage and the initial air pressure value X is within an allowable tolerance range (less than 10%). If so, the third indicator light 10 lights up green, indicating that the dual-channel pipeline is not blocked and has good airtightness; if the indicator light 10 lights up red, the buzzer sounds an alarm, and the detection is interrupted.

[0065] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0066] In this embodiment of the invention, the device controls the opening and closing of the first solenoid valve, the second solenoid valve, and the third solenoid valve respectively through a controller. By reading the air pressure value of the pressure gauge 2 and comparing it with the initial air pressure value X, the sealing and blockage of the dual-channel pipeline can be detected together. By comparing the air pressure values, not only can the blockage of the dual-channel pipeline be detected, but also the degree of blockage can be detected. The dual-channel pipeline only needs to be installed and removed once during the detection process, resulting in high detection efficiency and good effect.
