[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Understandably, referring to Figures 1 to 5 This utility model discloses a balloon appearance inspection device for a uterine dilation balloon catheter, comprising a base 100, a cylinder 200, a syringe 400, and a control valve 600. The output end of the cylinder 200 is connected to a pusher 300. The syringe 400 includes a syringe barrel 410 and a pusher 420. The syringe barrel 410 is fixedly mounted on the base 100, and its outlet end is provided with a vent 411. The vent 411 is connected to a Luer connector 500, which is used to connect to the inlet end of the uterine dilation balloon catheter. The pusher 420 is slidably connected to the syringe barrel 410, and one end of the pusher 420 is engaged with the pusher 300. The cylinder 200 drives the pusher 300 to move closer to or further away from the syringe barrel 410, so that the pusher 300 pushes the pusher 420 to move, thereby outputting gas from the syringe barrel 410. The control valve 600 is connected to the cylinder 200 and controls the working direction of the cylinder 200.

[0028] In use, the Luer connector 500 is connected to the air inlet of the uterine dilation balloon catheter. The working direction of the cylinder 200 is controlled by the control valve 600. The cylinder 200 drives the pusher head 300 to move closer to the syringe barrel 410, causing the pusher head 300 to push the push rod 420. The push rod 420 compresses and pushes the gas in the syringe barrel 410 to be discharged through the exhaust port 820, and then delivers gas along the Luer connector 500 to the balloon of the uterine dilation balloon catheter, causing the balloon to inflate. This facilitates the examination of the balloon's appearance after inflation, replacing manual inflation, reducing labor intensity, and improving testing efficiency. After the test is completed, the cylinder 200 drives the pusher head 300 to move away from the syringe barrel 410, thereby moving the push rod 420 back to its original position, ready for the next balloon test.

[0029] In addition, connecting the air inlet of the uterine dilation balloon catheter via the Luer connector 500 can improve the airtightness of the connection, thereby improving the stability of inflation.

[0030] It should be noted that the control valve 600 can be a manual directional valve or a solenoid directional valve, which can indirectly control the action of the cylinder 200 by controlling the flow of gas, thereby changing the working direction of the cylinder 200.

[0031] The air vent 820 and the Luer connector 500 are connected by a hose, which allows for easy adjustment of the position and orientation of the Luer connector 500, thus facilitating the connection of the Luer connector 500 to the air inlet of the uterine dilation balloon catheter.

[0032] A support leg 130 can be installed at each of the four corners of the bottom of the base 100. The support leg 130 is made of rubber, which can increase the friction between the support leg 130 and the placement platform, thereby improving the positional stability of the base 100.

[0033] Understandably, referring to Figure 1 , Figure 3 and Figure 5 The base 100 is equipped with a bracket 110, and a semi-circular slot 111 is formed at the upper end of the bracket 110, into which the syringe 410 is snapped. The semi-circular slot 111 at the upper end of the bracket 110 facilitates the snap-fit ​​installation of the syringe 410, making it easy to disassemble and replace. Furthermore, the semi-circular slot 111 matches the shape of the syringe 410, improving the stability of the syringe 410's installation position.

[0034] It should be noted that there can be two supports 110. The two supports 110 are arranged sequentially along the axial direction of the push rod 420. By supporting and fixing the injection cylinder 410 with the two supports 110 at the same time, the positional stability of the injection cylinder 410 can be improved.

[0035] A retaining ring is provided on the outer side of the end of the syringe 410 near the cylinder 200. The retaining ring abuts against the bracket 110 to restrict the movement of the syringe 410 away from the cylinder 200, thereby improving the positional stability of the syringe 410.

[0036] Specifically, refer to Figure 1 , Figure 3 and Figure 5 The syringe 410 is fitted with a semi-circular retaining sleeve 120, which is fixedly connected to the bracket 110 by bolts. The semi-circular retaining sleeve 120, in conjunction with the bracket 110, clamps and fixes the syringe 410 in place, improving its positional stability. Furthermore, since the semi-circular retaining sleeve 120 is fixed to the bracket 110 by bolts, it can be easily removed by loosening the bolts, facilitating the extraction of the syringe 410.

[0037] Understandably, referring to Figure 1 and Figure 4The pusher head 300 has a vertically penetrating T-shaped slot 310, and one end of the push rod 420 is provided with a circular baffle 421, which can be inserted into the T-shaped slot 310. Because the pusher head 300 has a vertically penetrating T-shaped slot 310 and one end of the push rod 420 is provided with a circular baffle 421, by inserting the circular baffle 421 from top to bottom into the T-shaped slot 310, one end of the push rod 420 can be easily fixedly connected to the pusher head 300. Furthermore, by the circular baffle 421 abutting against the side wall of the T-shaped slot 310, the pusher head 300 can push the circular baffle 421 to move, thereby driving the push rod 420 to move and output the gas from the syringe 410.

[0038] Understandably, referring to Figures 1 to 3 The cylinder 200 includes a cylinder body 210 and a piston rod 220. The cylinder body 210 is fixedly mounted on the base 100, and the piston rod 220 is slidably connected to the cylinder body 210. The piston rod 220 can move towards or away from the syringe 410. A pusher head 300 is threadedly connected to one end of the piston rod 220. By moving the piston rod 220 towards or away from the syringe 410, the pusher head 300 is moved, thereby moving the push rod 420, which improves the stability of the push rod 420's movement. In addition, since the pusher head 300 is threadedly connected to one end of the piston rod 220, the pusher head 300 can be easily disassembled and replaced by rotating it to accommodate the snap-fit ​​installation of push rods 420 of different sizes.

[0039] Specifically, refer to Figure 1 and Figure 2 The piston rod 220, at the end furthest from the pusher head 300, is threadedly connected to a limiting block 230. The limiting block 230 abuts against the cylinder body 210 to restrict the piston rod 220 from moving closer to the syringe barrel 410. By limiting the piston rod 220's movement towards the syringe barrel 410 through the limiting block 230 abutting against the cylinder body 210, the stroke of the piston rod 220 can be controlled, reducing the possibility of the pusher head 300 damaging the syringe 400. Furthermore, since the limiting block 230 is threadedly connected to the piston rod 220, its axial position on the piston rod 220 can be adjusted by rotating it, thereby adjusting the stroke range of the piston rod 220 and consequently the stroke range of the pusher rod 420, to accommodate different inflation volume requirements.

[0040] Specifically, refer to Figure 1 and Figure 2The piston of piston rod 220 divides the inner cavity of cylinder 210 into two air chambers 211. Control valve 600 is provided with two air outlet connectors 610 and one air inlet connector 620. The two air outlet connectors 610 are connected to the two air chambers 211 respectively. The air inlet connector 620 is used to connect to an external air pump. Control valve 600 is used to control the air inlet connector 620 to open the two air outlet connectors 610 respectively, so as to control the movement of piston rod 220. The control valve 600 controls the air inlet connector 620 to connect to the two air outlet connectors 610 respectively. When the air inlet connector 620 connects to one of the air outlet connectors 610, the external air pump can supply air to the air chamber 211 connected to the air outlet connector 610, which increases the air pressure in the air chamber 211 on that side, thereby driving the piston of the piston rod 220 to move to the other air chamber 211, so as to drive the piston rod 220 to move. Similarly, when the air inlet connector 620 connects to the other air outlet connector 610, the piston rod 220 moves in the opposite direction, thereby driving the piston rod 220 to move in the opposite direction, thus controlling the extension and retraction of the piston rod 220.

[0041] Specifically, refer to Figure 1 and Figure 2 The outlet connector 610 is connected to the air chamber 211 via a speed regulating valve 700. The speed regulating valve 700 is used to adjust the gas flow rate in the input air chamber 211, thereby adjusting the moving speed of the piston rod 220. Adjusting the gas flow rate in the input air chamber 211 by the speed regulating valve 700 to adjust the moving speed of the piston rod 220 can improve the stability and controllability of the piston rod 220's movement, thereby reducing the possibility of damage to the push rod 420 due to excessive piston rod 220 moving speed.

[0042] Understandably, referring to Figure 1 and Figure 3 The vent 411 is connected to a three-way check valve 800. The three-way check valve 800 includes an inlet 810 and an outlet 820. The inlet 810 is connected to an inlet duct 900, and the outlet 820 is connected to a Luer connector 500. When gas in the syringe 410 is discharged from the vent 411, the three-way check valve 800 controls the vent 411 to connect to the exhaust vent 820, and simultaneously controls the disconnection between the vent 411 and the inlet vent 810, allowing gas to be delivered from the exhaust vent 820 and the Luer connector 500 to the balloon of the uterine dilation balloon catheter. When gas needs to be filled into the syringe 410 from the vent 411 after the exhaust is completed, the three-way check valve 800 controls the vent 411 to connect to the inlet vent 810, and simultaneously controls the disconnection between the vent vent 411 and the exhaust vent 820, allowing external gas to flow into the syringe 410 from the inlet conduit 900 and the inlet vent 810, and preventing gas in the balloon from flowing back into the syringe 410, thus maintaining the balloon's inflated state and facilitating the inspection of the balloon's appearance.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
