Description

Technical Field

[0001] The utility model relates to the technical field of medical device detection equipment, and particularly relates to an airtightness detection device for tubular medical devices. Background Technique

[0002] There are airtightness requirements for tubular medical devices used in a closed manner. If the airtightness is insufficient, it will affect the use effect. Therefore, it is usually necessary to detect its airtightness first. However, the relevant industry standards only roughly write out the test methods. If the test is carried out according to this brief method, there are disadvantages such as complex operation, low efficiency, and easy occurrence of misoperation, resulting in the need for re-detection.

[0003] For example, the utility model with the publication number CN21867467U discloses an airtightness detection device for tubular medical devices, including a mounting base. A detection mechanism is arranged at the center of the mounting base. The detection mechanism includes a pressure detector, and the pressure detector extends into the interior of the tubular medical device. An air inflation pump is arranged outside the pressure detector. A tubular medical device is arranged above the detection mechanism. Clamping mechanisms are arranged on both the left and right sides of the tubular medical device. The utility model aims to solve the problems that the existing airtightness detection is complex in operation and prone to misoperation, resulting in the need for re-detection, and the existing pipeline airtightness test device immerses the pipe body in water and judges the airtightness by observing bubbles, and the product will contact the water source, resulting in the risk of excessive initial pollution bacteria.

[0004] In the process of implementing the present application, it is found that the following problems exist in this technology: When the existing airtightness detection device for tubular medical devices is in use, the air pressure inside the tubular medical device is observed by inputting gas to detect the airtightness inside the tubular medical device. However, the connection between most tubular medical devices and the sealing mechanism cannot be adjusted, so that the device can only detect a single group and single model of tubular medical devices during subsequent use, thus reducing the practicability of the device.

[0005] Therefore, an airtightness detection device for tubular medical devices is proposed. Summary of the Utility Model

A connecting plate is arranged on the lower surface of the cross-shaped slider. A groove is formed on the lower surface of the connecting plate. Through holes are formed in the inner walls on the left and right sides of the groove of the connecting plate. A bidirectional threaded rod is rotatably connected inside the two groups of through holes of the connecting plate. A motor is arranged on one side of the connecting plate. The output shaft of the motor passes through one group of through holes of the connecting plate and is installed on one side of the bidirectional threaded rod. Two groups of positioning plates are threadedly connected to the outside of the bidirectional threaded rod. Spring telescopic rods are arranged on the adjacent sides of the two groups of positioning plates. Arc-shaped positioning blocks are arranged at the adjacent ends of the two groups of spring telescopic rods.

[0010] Furthermore, the warning mechanism comprises an alarm, two groups of contact switches and two groups of fixing rods. The alarm is installed on the upper surface of the U-shaped fixing plate. The two groups of contact switches are respectively installed on the adjacent sides of the two groups of positioning plates. The two groups of fixing rods are respectively installed on the opposite sides of the two groups of arc-shaped positioning blocks. The positions of the two groups of contact switches are respectively located on the moving paths of the two groups of fixing rods.

[0027] Such as Figures 1 to 5As shown in the figure, an airtightness detection device for a tubular medical device includes a working platform 1. Inside the working platform 1, there is a support plate 2. On the upper surface of the support plate 2, there is an air compressor 10. On the upper surface of the working platform 1, a U-shaped fixing plate 3 is installed. At the top of the inner wall of the U-shaped fixing plate 3, there is a sealing gasket 5. On the front surface of the sealing gasket 5, there is a fixing plate 4. Through holes are opened on the front surfaces of both the fixing plate 4 and the sealing gasket 5. A connecting pipe 6 is inserted into the through holes of the fixing plate 4 and the sealing gasket 5. The air inlet end of the connecting pipe 6 is installed inside the exhaust port of the air compressor 10. Grooves are opened on the front surfaces of both the fixing plate 4 and the sealing gasket 5. Inside the grooves of the fixing plate 4 and the sealing gasket 5, there is a pressure detector 11. A groove is opened on the upper surface of the U-shaped fixing plate 3. Inside the groove of the U-shaped fixing plate 3, there is a clamping mechanism 7 that drives the tubular medical device to move. Inside the clamping mechanism 7, there is a warning mechanism 9. On the upper surface of the U-shaped fixing plate 3, there is a support mechanism 8;

[0028] Specifically, by starting the clamping mechanism 7 to clamp the tubular medical device and drive the tubular medical device to move, the opening of the tubular medical device is abutted against the front surface of the sealing gasket 5. Then, by starting the air compressor 10, gas is input into the tubular medical device along the connecting pipe 6, so that subsequent staff can check the airtightness of the tubular medical device by observing whether the value of the pressure detector 11 decreases; since the inner contour of the clamping mechanism 7 can be adjusted, and then the sealing gasket 5 covers the front surface of the fixing plate 4, the clamping mechanism 7 can clamp different models and types of tubular medical devices for detection during subsequent use, thus expanding the detection range of the subsequent device.

[0029] As Figures 1 to 5 shown in the figure, the clamping mechanism 7 includes a top plate 701 and a cross-shaped slider 703. The top plate 701 is installed on the upper surface of the U-shaped fixing plate 3. On the front surface of the top plate 701, there is an electric telescopic rod 702. The cross-shaped slider 703 is slidably connected inside the groove of the U-shaped fixing plate 3. On the lower surface of the cross-shaped slider 703, there is a connecting plate 704. A groove is opened on the lower surface of the connecting plate 704. Through holes are opened on the inner walls of the left and right sides of the groove of the connecting plate 704. Inside the two through holes of the connecting plate 704, there is a bidirectional threaded rod 708 rotatably connected. On one side of the connecting plate 704, there is a motor 709. The output shaft of the motor 709 passes through one of the through holes of the connecting plate 704 and is installed on one side of the bidirectional threaded rod 708. Two positioning plates 705 are threadedly connected to the outside of the bidirectional threaded rod 708. On the adjacent sides of the two positioning plates 705, there is a spring telescopic rod 706. On the adjacent ends of the two spring telescopic rods 706, there is an arc-shaped positioning block 707;

[0030] Specifically, when the subsequent tubular medical device is placed between the two groups of arc-shaped positioning blocks 707, the motor 709 is started to drive the bidirectional threaded rod 708 to trigger the two groups of positioning plates 705, two groups of spring telescopic rods 706 and two groups of arc-shaped positioning blocks 707 to move, and the tubular medical device is clamped between the two groups of arc-shaped positioning blocks 707, and then the electric telescopic rod 702 is started to drive the cross-shaped slider 703 and the tubular medical device at the lower end of the cross-shaped slider 703 to move, so that the opening of the tubular medical device is abutted against the front of the sealing pad 5, and the sealing pad 5 is covered on the front of the fixed plate 4, so that the subsequent clamping mechanism 7 can clamp tubular medical devices of different models and types for detection during use, thereby expanding the subsequent detection range of the device and thus improving the practicality of the device.

[0031] like Figure 2 and Figure 4 As shown, the warning mechanism 9 includes an alarm 901, two groups of contact switches 902 and two groups of fixing rods 903. The alarm 901 is installed on the upper surface of the U-shaped fixing plate 3, the two groups of contact switches 902 are respectively installed on the adjacent side of the two groups of positioning plates 705, and the two groups of fixing rods 903 are respectively installed on the opposite side of the two groups of arc-shaped positioning blocks 707. The positions of the two groups of contact switches 902 are respectively located on the moving paths of the two groups of fixing rods 903, and the two groups of contact switches 902 and the control end of the alarm 901 are electrically connected; specifically, through the two groups of contact switches, The position of the point switch 902 is located on the moving path of the two groups of fixed rods 903, so that when the two groups of spring telescopic rods 706 are squeezed, the two groups of fixed rods 903 move, triggering the two groups of contact switches 902 to start the alarm 901 to sound an alarm, thereby facilitating the subsequent staff to promptly shut down the motor 709 to drive the two groups of arc-shaped positioning blocks 707 to move, thereby avoiding excessive squeezing of the tubular medical device by the subsequent clamping mechanism 7 during use, thereby causing damage to the tubular medical device, thereby improving the practicality of the subsequent device during use.

[0032] like Figure 5 As shown, a groove is provided at the top of the inner wall of the U-shaped fixing plate 3, and an ultraviolet disinfection lamp 12 is arranged inside the groove of the U-shaped fixing plate 3, and the position of the ultraviolet disinfection lamp 12 is located directly above the sealing gasket 5; specifically, the ultraviolet disinfection lamp 12 is started to sterilize the sealing gasket 5 and the tubular medical instruments in front of the sealing gasket 5 with ultraviolet light, so as to avoid bacteria growing on the front side of the sealing gasket 5 during the placement process of the subsequent sealing gasket 5, which may cause the subsequent multiple groups of tubular medical instruments to be contaminated by the sealing gasket 5 during the detection process, thereby improving the safety of the sealing gasket 5 during use.

[0033] like Figure 1As shown in the figure, the support mechanism 8 includes a support rod 801. The support rod 801 is installed on the upper surface of the working platform 1. An arc-shaped support plate 802 is provided at the top of the support rod 801. The position of the arc-shaped support plate 802 is directly below the moving paths of the two groups of arc-shaped positioning blocks 707. Specifically, since the position of the arc-shaped support plate 802 is directly below the moving paths of the two groups of arc-shaped positioning blocks 707, when the two groups of arc-shaped positioning blocks 707 move subsequently, they can clamp the tubular medical device placed on the upper surface of the arc-shaped support plate 802. As a result, when the subsequent staff clamps the tubular medical device between the two groups of arc-shaped positioning blocks 707, there is no need for the hand to support the tubular medical device, thus minimizing the risk of the tubular medical device being scratched by fragments in case it breaks during the clamping process by the subsequent clamping mechanism 7. Therefore, the safety of the subsequent staff during the detection of the tubular medical device using this device is improved.

[0034] As Figure 1 and Figure 2 As shown in the figure, the sealing gasket 5 is made of coarse-pore silica gel. Specifically, due to the good heat resistance of the coarse-pore silica gel material, the sealing gasket 5 is less likely to be damaged after being irradiated by the ultraviolet disinfection lamp 12 for a long time during subsequent use. Therefore, the service life of the sealing gasket 5 is extended.

[0035] In summary: By starting the motor 709 to drive the bidirectional threaded rod 708 to trigger the movement of the two groups of positioning plates 705, the two groups of spring telescopic rods 706, and the two groups of arc-shaped positioning blocks 707, the tubular medical device is clamped between the two groups of arc-shaped positioning blocks 707. Then, by starting the electric telescopic rod 702 to drive the cross-shaped slider 703 and the tubular medical device at the lower end of the cross-shaped slider 703 to move, the opening of the tubular medical device is abutted against the front surface of the sealing gasket 5, and the sealing gasket 5 covers the front surface of the fixing plate 4, enabling the subsequent clamping mechanism 7 to clamp and detect different models and types of tubular medical devices during use, thereby expanding the detection range of this device. Since the positions of the two groups of contact switches 902 are on the moving paths of the two groups of fixed rods 903, when the two groups of spring telescopic rods 706 are squeezed subsequently, the two groups of fixed rods 903 move to trigger the two groups of contact switches 902 to activate the alarm 901 to emit an alarm, which facilitates the subsequent staff to promptly shut down the motor 709 to drive the two groups of arc-shaped positioning blocks 707 to move, thus minimizing the risk of the tubular medical device being damaged due to excessive extrusion by the subsequent clamping mechanism 7 during use.

[0036] Meanwhile, the ultraviolet disinfection lamp 12 is activated to perform ultraviolet disinfection on the gasket 5 and the tubular medical device on the front side of the gasket 5, so as to avoid as much as possible the subsequent bacterial growth on the front side of the gasket 5 during the placement process, which may cause the subsequent multi-group tubular medical devices to be contaminated by the gasket 5 during the detection process.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
