Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically, it relates to a sealing test device for disposable endoscope protective sleeves. Background Technology

[0002] An endoscope is a medical diagnostic instrument with an image sensor, optical lens, and light source. It can be inserted into the stomach through the mouth or other natural orifices. Endoscopes can visualize lesions that cannot be seen with X-rays, making them extremely useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and develop the best treatment plan accordingly.

[0003] Disposable endoscope protective sleeves are primarily used to protect the endoscope inlet of the connecting cavity, isolating and protecting the endoscope to prevent cross-infection during endoscopic use and improve surgical safety. These sleeves are typically made of disposable plastic or silicone and are discarded after use. If the sleeve has holes, its seal is poor, allowing pathogens to spread through the holes during endoscopic examinations, potentially infecting both doctors and patients. Therefore, it is necessary to test the seal's tightness to select qualified sleeves.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A sealing performance testing device for disposable endoscope protective sleeves includes a base and a mounting base. An mounting head is fixedly mounted at the bottom of the mounting base, and a sleeve connector is fixedly mounted at the bottom of the mounting head. An air outlet pipe is fixedly mounted inside the sleeve connector, with its bottom end extending to the outside of the bottom of the sleeve connector. A water tank is fixedly mounted on the top outer wall of the base, located directly below the sleeve connector. An air supply pipe is mounted on the mounting head, connected to the air outlet pipe. One end of the air supply pipe is connected to an air bladder, which has a valve. A mounting groove is formed at the top of the mounting base, and a horizontal plate is slidably mounted inside the mounting groove. A symmetrically arranged mounting bracket is fixedly connected to both sides of the horizontal plate. A connecting rod is hinged to each of the two mounting brackets. A symmetrically arranged positioning clamp is slidably installed at the bottom of the mounting base. The two positioning clamps are symmetrically arranged on both sides of the mounting head, and an arc-shaped groove is opened on the opposite side of each positioning clamp. A guide bracket is fixedly installed on one outer wall of each of the two positioning clamps. One end of each of the two connecting rods is hinged to the two guide brackets. A threaded rod is rotatably installed on one inner wall of the mounting groove. A threaded hole is opened in the middle of the horizontal plate, and the threaded rod is screwed into the inner wall of the threaded hole. A knob is fixedly connected to the end of the threaded rod.

[0007] In a preferred embodiment of this utility model, a fixing rod is fixedly connected to one side of the outer wall of each of the two positioning clamps, and a guide bracket is fixedly connected to the end of the fixing rod.

[0008] In a preferred embodiment of this utility model, the mounting base has symmetrically arranged rectangular movable openings on both sides, and the connecting rod is located inside the rectangular movable opening.

[0009] In a preferred embodiment of this utility model, an installation plate is fixedly connected to one outer wall of the top of the base, a lifting rail is fixedly connected to one outer wall of the installation plate, a guide seat is slidably arranged on the inner wall of the lifting rail, and the installation seat is fixedly connected to one outer wall of the guide seat.

[0010] In a preferred embodiment of this utility model, an L-shaped fixing bracket is fixedly connected to the top outer wall of the mounting plate, and a cylinder is fixedly installed on the top of the fixing bracket, with the cylinder piston rod connected to the top outer wall of the guide seat.

[0011] In a preferred embodiment of this utility model, the bottom of the mounting base is provided with symmetrically arranged movable grooves, and the two sides of the positioning clamp are fixedly connected with symmetrically arranged L-shaped connecting plates, and the connecting plates are slidably connected to the inner wall of the movable grooves.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model involves fitting a protective sleeve onto a connector, with the top of the protective sleeve resting on an mounting head. After fitting, rotating a knob causes a threaded rod to rotate, which in turn moves a horizontal plate. The horizontal plate then moves two mounting brackets. Two guide supports, in conjunction with the design, change the inclination angle of the two connecting rods. This change in inclination angle causes the two positioning clamps to move relative to each other until the arc-shaped grooves on opposite sides of the positioning clamps contact the top two sides of the protective sleeve, thus clamping and positioning the protective sleeve. After positioning, the mounting base is moved downwards, causing the mounting base to move the sleeve with the protective sleeve downwards until the protective sleeve is completely lowered into the water tank containing water. Then, the valve of the air bladder is opened and the air bladder is squeezed to deliver gas into the protective sleeve through the gas supply pipe and the gas outlet pipe. When the gas is delivered into the protective sleeve, observe whether air bubbles are generated in the water tank. If air bubbles are generated, it indicates that there are holes in the protective sleeve and the sealing is poor. If no air bubbles are generated, it indicates that the protective sleeve has good sealing. This completes the sealing test of the disposable endoscope protective sleeve, which facilitates the screening of qualified protective sleeves.

A water tank 6 is fixedly mounted on the top outer wall of the base 1, located directly below the sleeve connector 8. An air supply pipe 12 is mounted on the mounting head 7, connected to the air outlet pipe 9. One end of the air supply pipe 12 is connected to an air bladder 13, which has a valve. A mounting groove 21 is formed on the top of the mounting base 5. A horizontal plate 22 is slidably installed on the inner side of the mounting base 5. Symmetrically arranged mounting brackets 23 are fixedly connected to both sides of the horizontal plate 22. Connecting rods 16 are hinged to both mounting brackets 23. Symmetrically arranged positioning clamps 14 are slidably installed on the bottom of the mounting base 5. Symmetrically arranged movable grooves 18 are opened at the bottom of the mounting base 5. Symmetrically arranged L-shaped connecting plates 19 are fixedly connected to both sides of the positioning clamps 14, and the connecting plates 19 are slidably connected to the inner wall of the movable grooves 18. Two positioning clamps 14 are symmetrically arranged on both sides of the mounting head 7, and each positioning clamp 14 has an arc-shaped groove on its opposite side. The outer wall of one side of each positioning clamp 14... Guide brackets 15 are fixedly installed on each of the two positioning clamps 14. Fixing rods 17 are fixedly connected to the outer walls of each of the two positioning clamps 14, and the guide brackets 15 are fixedly connected to the ends of the fixing rods 17. One end of each of the two connecting rods 16 is hinged to the two guide brackets 15. A threaded rod 24 is rotatably installed on the inner wall of one side of the mounting groove 21. A threaded hole is opened in the middle of the horizontal plate 22, and the threaded rod 24 is screwed onto the inner wall of the threaded hole. A knob 25 is fixedly connected to the end of the threaded rod 24. The protective sleeve is placed on the socket 8, and the top of the protective sleeve is placed on the mounting head 7. After placement, the knob 25 is rotated. 5 drives the threaded rod 24 to rotate, the threaded rod 24 drives the horizontal plate 22 to move, the horizontal plate 22 drives the two mounting brackets 23 to move, and the two guide brackets 15 set in cooperation change the tilt angle of the two connecting rods 16. When the tilt angle of the two connecting rods 16 changes, the two guide brackets 15, the two fixed rods 17, the movable groove 18 and the connecting plate 19 set in cooperation can drive the two positioning clamps 14 to move relative to each other until the arc-shaped grooves opened on the opposite side of the two positioning clamps 14 contact the two sides of the top of the protective sleeve, so as to realize the clamping and positioning function of the protective sleeve.

[0024] In a specific embodiment, the mounting base 5 has symmetrically arranged rectangular movable openings 20 on both sides, and the connecting rod 16 is located inside the rectangular movable openings 20. A mounting plate 2 is fixedly connected to the outer wall of one side of the top of the base 1, and a lifting rail 3 is fixedly connected to the outer wall of one side of the mounting plate 2. A guide seat 4 is slidably arranged on the inner wall of the lifting rail 3. The mounting base 5 is fixedly connected to the outer wall of one side of the guide seat 4. An L-shaped fixing bracket 10 is fixedly connected to the outer wall of the top of the mounting plate 2. A cylinder 11 is fixedly installed on the top of the fixing bracket 10. The piston rod of the cylinder 11 is connected to the outer wall of the top of the guide seat 4. After the protective sleeve is positioned, the cylinder 11 is activated, and the cylinder 11 cooperates with the lifting mechanism. Track 3 drives guide seat 4 to move downwards, guide seat 4 drives mounting seat 5 to move downwards, and mounting seat 5 drives sleeve joint 8 with protective sleeve to move downwards until the protective sleeve is completely lowered into water tank 6 containing water. Then, the valve of airbag 13 is opened and airbag 13 is squeezed to deliver gas into the protective sleeve through air supply pipe 12 and air outlet pipe 9. When the gas is delivered into the protective sleeve, observe whether air bubbles are generated in water tank 6. If air bubbles are generated, it indicates that there are holes in the protective sleeve and the sealing is poor. If no air bubbles are generated, it indicates that the protective sleeve has good sealing. This completes the sealing test of disposable endoscope protective sleeves and facilitates the screening of qualified protective sleeves.

[0025] The implementation principle of the sealing performance testing device for disposable endoscope protective sleeves in this embodiment is as follows:

[0026] In practical use, the protective sleeve is fitted onto the connector 8, and the top of the protective sleeve is fitted onto the mounting head 7. After fitting, the knob 25 is rotated, which drives the threaded rod 24 to rotate. The threaded rod 24 drives the horizontal plate 22 to move, and the horizontal plate 22 drives the two mounting brackets 23 to move. The two guide brackets 15, which are provided in conjunction, change the tilt angle of the two connecting rods 16. When the tilt angle of the two connecting rods 16 changes, the two guide brackets 15, the two fixed rods 17, the movable groove 18, and the connecting plate 19 can drive the two positioning clamps 14 to move relative to each other until the arc-shaped grooves on the opposite side of the two positioning clamps 14 contact the two sides of the top of the protective sleeve, thereby clamping the protective sleeve. The positioning function is as follows: after the protective sleeve is positioned, the cylinder 11 is activated. The cylinder 11, in conjunction with the lifting rail 3, moves the guide seat 4 downward. The guide seat 4 moves the mounting seat 5 downward. The mounting seat 5 moves the sleeve joint 8, which is fitted with the protective sleeve, downward until the protective sleeve is completely lowered into the water tank 6 containing water. Then, the valve of the airbag 13 is opened and the airbag 13 is squeezed, which allows gas to be delivered into the protective sleeve through the air supply pipe 12 and the air outlet pipe 9. When the gas is delivered into the protective sleeve, observe whether air bubbles are generated in the water tank 6. If air bubbles are generated, it indicates that there are holes in the protective sleeve and the sealing performance is poor. If no air bubbles are generated, it indicates that the protective sleeve has good sealing performance, thus completing the sealing performance test of the disposable endoscope protective sleeve.
