Description

Technical Field

[0001] The utility model relates to the field of medical devices, and more specifically, to a balloon cleaner provided with a needle protection mechanism. Background Art

[0002] A balloon cleaner is a device used for nasal cavity cleaning. It mainly consists of a balloon and a syringe. The balloon is a hollow tubular object with elasticity inside, which can store and transport liquid. When the liquid passes through the syringe, the balloon will expand, thereby increasing the contact area between the liquid and the nasal mucosa to achieve the purpose of cleaning the nasal cavity.

[0003] Currently, the needles of existing balloon cleaners usually do not have a protection structure. This causes external dust and other impurities to enter the balloon cleaner from the needle during use, contaminating the liquid medicine inside the cleaner, posing a great potential safety hazard to medicine preparation, and greatly affecting the use of the balloon cleaner.

[0023] Embodiment

[0024] Please refer to Figures 1-4 , the present utility model provides a balloon cleaner provided with a needle protection mechanism, including a tube body 100 and a protection device 200.

[0025] Among them, the protection device 200 is installed on the surface of the tube body 100. Through the protection device 200, the needle 120 can be protected, reducing the possibility that external dust and other impurities will enter the balloon cleaner from the needle 120 during use and contaminating the liquid medicine inside the cleaner.

[0026] Please refer to Figures 1-2 , the balloon body 110 is threadedly connected to the top of the tube body 100, and a needle 120 is provided on the lower surface of the tube body 100. A convex ring 130 is connected to the top of the tube body 100. In specific implementation, when the index finger and the middle finger are in contact with the lower surface of the convex ring 130 and the thumb presses the balloon body 110 again, the liquid medicine can be ejected from the needle 120, which is beneficial for flushing the nasal cavity.

[0027] In this embodiment, a stud 111 is connected to the lower surface of the balloon body 110, and the stud 111 is threadedly connected to the upper end of the tube body 100; the convex ring 130 is located below the balloon body 110, and a fixing plate 131 is connected to the surface of the convex ring 130. During specific implementation, by bringing the index finger and middle finger into contact with the lower surface of the fixing plate 131 and then pressing the balloon body 110, it is beneficial to increase the possibility of spraying the liquid medicine into the nasal cavity.

[0028] Please refer to Figures 1-4 , the protection device 200 includes a connecting member 210 and a spring 220. A fixing block 140 is connected to the surface of the tube body 100. The connecting member 210 is installed on the lower surface of the fixing block 140, and a sliding seat 230 is slidably sleeved on the surface of the connecting member 210. The spring 220 is sleeved on the surface of the connecting member 210, and both ends of the spring 220 are respectively connected to the inside of the connecting member 210 and the sliding seat 230. The bottom of the sliding seat 230 is rotatably connected to a protective sleeve 240, and the protective sleeve 240 is sleeved on the surface of the needle 120. During specific implementation, by pulling the sliding seat 230 downward so that it moves downward along the surface of the connecting member 210, the possibility that the moving track of the sliding seat 230 will deviate during the moving process is reduced, and the sliding seat 230 will drive the protective sleeve 240 to move downward. By rotating the protective sleeve 240 so that it is located directly below the needle 120, due to the elastic force of the spring 220, the sliding seat 230 can move upward, thereby driving the protective sleeve 240 to move upward, so that the protective sleeve 240 is sleeved on the surface of the needle 120, and the protective sleeve 240 cannot fall off from the needle 120, which is beneficial to protecting the needle 120 and reducing the possibility that external dust and other impurities will enter the balloon cleaner from the needle 120 and contaminate the liquid medicine inside the cleaner.

[0029] In this embodiment, the connecting member 210 includes a connecting rod 211 and a limiting block 212. The connecting rod 211 is fixedly connected to the fixing block 140 and the limiting block 212 respectively. The limiting block 212 is connected to the lower end of the spring 220. The spring 220 is sleeved on the surface of the connecting rod 211, and the limiting block 212 is slidably arranged inside the sliding seat 230; a limiting groove 231 is formed inside the sliding seat 230, and the limiting block 212 is in contact with the inner wall of the limiting groove 231. The upper end of the spring 220 is connected to the top wall of the limiting groove 231. During specific implementation, when the sliding seat 230 moves downward, the possibility that the sliding seat 230 falls off from the surface of the connecting rod 211 is reduced through the cooperation of the limiting block 212 and the limiting groove 231. Setting the spring 220 inside the limiting groove 231 is beneficial to protecting the spring 220.

[0030] A sealing ring 250 is connected to the surface of the limiting block 212. The sealing ring 250 is in contact with the inner wall of the limiting groove 231. In specific implementation, the sealing ring 250 is provided on the surface of the limiting block 212 here, reducing the possibility of wear when the limiting block 212 contacts the limiting groove 231. It should be noted that the sealing ring 250 can be made of rubber or silica gel; a connecting block 241 is connected to the surface of the protective sleeve 240, and the connecting block 241 is rotatably installed at the bottom of the sliding seat 230.

[0031] A connecting ring 150 is sleeved on the surface of the tube body 100, and a supporting block 151 is connected to the surface of the connecting ring 150. In specific implementation, when the protective sleeve 240 is no longer sleeved on the needle 120, through the elastic force of the spring 220, the sliding seat 230 can move upward. By manually rotating the supporting block 151 on the connecting ring 150, the supporting block 151 can be located directly below the sliding seat 230, restricting the sliding seat 230 and reducing the possibility of the sliding seat 230 sliding downward.

[0032] Specifically, the working principle of the balloon cleaner provided with the needle protection mechanism: When in use, by contacting the index finger and middle finger with the lower surface of the fixing plate 131 of the convex ring 130 and then pressing the balloon body 110, the liquid medicine can be ejected from the tube body 100 and the needle 120, which is beneficial for cleaning the nasal cavity. By moving the sliding seat 230 downward so that it moves downward along the surface of the connecting rod 211 on the fixing block 140, it is beneficial for the stability of the sliding seat 230 during the movement. Then rotate the connecting block 241 to make the protective sleeve 240 located directly below the needle 120. Through the elastic force of the spring 220, the sliding seat 230 can move upward, and the protective sleeve 240 will be sleeved on the surface of the needle 120, which is beneficial for protecting the needle 120 and reducing the possibility that external dust and other impurities will enter the balloon cleaner from the needle 120 and contaminate the liquid medicine inside the cleaner.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
