Description

Technical Field

[0001] The utility model relates to the technical field of isolation shoe covers, and in particular to an air tightness detection device for medical isolation shoe covers. Background Art

[0002] Isolation shoe covers are a type of protective equipment used to protect shoes. They are usually used in medical, laboratory, food processing and other environments where high hygiene standards must be maintained to prevent contact with potentially infectious blood, body fluids, secretions, etc. of patients, and play a barrier and protective role. Therefore, the air tightness of the produced medical isolation shoe covers needs to be tested to ensure that the shoe covers can play a barrier and protective role, which requires the use of corresponding air tightness testing devices.

[0003] After searching, the Chinese patent publication number CN217505102U disclosed "a medical isolation shoe cover air tightness detection and sorting device, including a base plate, a table, an inflation tube and a sorting mechanism, the table is fixed to the top rear end of the base plate, the inflation tube is fixed to the top left side of the table, and the lower side wall of the inflation tube is connected to the air source; the sorting mechanism includes side plates, a back plate, a cylinder and a pressure plate, the two side plates and the back plate are connected in an inverted "concave" structure, the bottom of the side plate is fixed to the top right side of the table, and the distance between the two side plates is not less than the length of the shoe cover; the inner wall of the cylinder is fixed below the front wall of the back plate, the bottom end of the piston rod of the cylinder is connected to the top of the pressure plate, and the width of the pressure plate is less than the distance between the side plates on both sides."

[0004] The above patent mainly performs air tightness testing on the isolation shoe cover by placing the opening of the isolation shoe cover on the inflation port of the inflation tube, then tying the opening of the shoe cover and the wall of the inflation tube by hand, and opening the inflation tube to test the air tightness of the shoe cover. However, when the air pressure inside the inflation port of the shoe cover increases, the hand needs to maintain a large grip force to ensure that the opening of the shoe cover and the wall of the inflation tube are in a sealed state. As the hand muscles fatigue, the grip force of the hand will decrease, thereby making the sealing between the opening of the shoe cover and the wall of the inflation tube insufficient and causing air leakage, which will affect the air tightness test result of the shoe cover. In view of this, the present invention proposes an air tightness testing device for medical isolation shoe covers. Utility Model Content

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 4As shown, this embodiment proposes an air tightness detection device for medical isolation shoe covers, including a detection frame 1, the top of the detection frame 1 is fixedly connected to an inflation sleeve 2 for placing the isolation shoe cover, the bottom of the inflation sleeve 2 is fixedly connected to an air inlet pipe 3, and an inflation mechanism 4 is provided on the inner side of the detection frame 1. The inflation mechanism 4 includes an air pump 41, and the air pump 41 is fixedly installed on the inner side of the detection frame 1. The air outlet end of the air pump 41 is fixedly connected to a tee pipe 42 through a conduit, and the two outlets of the tee pipe 42 are fixedly connected to a first air guide pipe 43, and the outlet ends of the two first air guide pipes 43 are fixedly connected to a transition tube 44, and one end of the two transition tubes 44 is fixedly connected to a second air guide pipe 45, and the outlet ends of the two second air guide pipes 45 are connected to the air inlet pipe 3. Both ends of the top of the detection frame 1 are provided with a sealing mechanism 5 for introducing gas into the transition tube 44 by cooperating with the first air guide pipe 43 to compress and seal the sleeve of the isolation shoe cover.

[0023] The opening of the isolation shoe cover is placed on the inflation sleeve 2, and then the air pump 41 is started to introduce gas into the two first air guide tubes 43. Then the two first air guide tubes 43 respectively introduce the gas into the two transition tubes 44, so that the pressure sealing mechanism 5 compresses and seals the opening of the isolation shoe cover. Then the two second air guide tubes 45 introduce the gas inside the transition tube 44 into the air inlet pipe 3, and then introduce the gas into the interior of the isolation shoe cover through the inflation sleeve 2, so that the internal air pressure of the isolation shoe cover increases and expands. The air tightness of the isolation shoe cover is judged by detecting whether the isolation shoe cover is leaking. The entire detection process can ensure that the opening of the isolation shoe cover is in a sealed state through the pressure sealing mechanism 5, effectively avoiding the problem that the opening of the isolation shoe cover leaks during detection and affects the air tightness detection result of the isolation shoe cover.

[0024] Furthermore, the pressure sealing mechanism 5 includes a movable rod 51, which passes through the top wall of the detection frame 1 and extends to the inner side of the detection frame 1. The detection frame 1 is slidably connected to the top wall of the detection frame 1. Both ends of the top of the detection frame 1 are provided with slide grooves 54 that match the movable rod 51. The two movable rods 51 can slide horizontally along the corresponding slide grooves 54. The top of the movable rod 51 is fixedly connected to a pressure plate 52. The pressure plate 52 is an arc-shaped structure. The inner side of the pressure plate 52 is fixedly connected to a corresponding sealing gasket. The bottom end of the movable rod 51 is fixedly connected to a connecting plate 53. The movable rod 51 is an L-shaped structure, and the horizontal section of the movable rod 51 is fixedly connected to the pressure plate 52. The bottom end of the connecting plate 53 is provided with an air pusher 4 that drives the connecting plate 53 to move horizontally by cooperating with the first air guide pipe 43 to introduce gas into the transition cylinder 44. 6. The air push member 46 includes a piston 461, which is slidably connected to the inner side of the transition cylinder 44. One end of the piston 461 is fixedly connected to a sliding rod 462. The sliding rod 462 passes through the side wall of the transition cylinder 44 and extends to the outside of the transition cylinder 44. The sliding rod 462 is slidably connected to the side wall of the transition cylinder 44. The end of the sliding rod 462 away from the piston 461 is fixedly connected to the connecting plate 53. A return spring 463 is provided on the sliding rod 462. One end of the return spring 463 contacts the piston 461, and the other end of the return spring 463 contacts the inner wall of the piston 461. When the return spring 463 is in a natural state, the piston 461 is located between the inlet and outlet ends of the transition cylinder 44. When the return spring 463 is in a fully compressed state, the piston 461 is located at the inlet and outlet ends of the transition cylinder 44 and is communicated with each other.

[0025] Working principle: First, the opening of the isolation shoe cover is placed on the inflatable sleeve 2, and then the air pump 41 is started to introduce gas into the two first air guide tubes 43. Then, the two first air guide tubes 43 respectively introduce the gas into the two transition tubes 44, which increases the air pressure inside the transition tube 44, causing the piston 461 to slide, which also causes the sliding rod 462 to slide synchronously and apply thrust to the connecting plate 53, so that the two connecting plates 53 move toward each other, so that the two movable rods 51 drive the two pressure plates 52 to move toward each other and contact the outer wall of the inflatable sleeve 2, thereby causing the two pressure plates 52 to press and seal the opening of the isolation shoe cover. This sealing method can greatly improve the sealing between the opening of the isolation shoe cover and the outer wall of the inflatable sleeve 2;

[0026] As the air pressure inside the transition tube 44 continues to increase, when the piston 461 slides and the return spring 463 is fully compressed, the inlet end and the outlet end of the transition tube 44 are connected, so that the second air guide tube 45 introduces the gas inside the transition tube 44 into the air inlet pipe 3, and then introduces the gas into the interior of the isolation shoe cover through the inflation sleeve 2, thereby increasing the air pressure inside the isolation shoe cover and expanding it. The air tightness of the isolation shoe cover is determined by detecting whether the isolation shoe cover is leaking.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
