Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and in particular to a medical device detection device used for medical detection. Background Art
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables, and their effectiveness is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.
[0003] Medical devices that are sealed with inert gas need to be confirmed to be sealed before use. When the package leaks, the medical devices inside may be contaminated with bacteria, which can easily cause infection to patients after use. Therefore, the sealing of the medical device packaging needs to be tested before use to ensure that the medical device is sterile.
[0004] To this end, we propose a medical device testing equipment for medical testing to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a medical device detection equipment for medical detection, so as to solve the problems raised in the above background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A medical device testing equipment for medical testing, comprising a box body, a sealing cover is provided on the upper end sealing cover of the box body, a placement plate is fixedly installed on the middle part of the bottom of the box body, the upper end surface of the placement plate is provided with a placement groove, and the parts of the placement plate located on both sides of the placement groove are installed with multiple fixing claws, two negative pressure plates are sealingly and slidably connected in the box body, and an adjustment mechanism for adjusting the two negative pressure plates is provided in the box body.
[0008] Furthermore, the adjusting mechanism includes two grooves arranged on the inner wall of the box body, and two bidirectional threaded rods are rotatably connected in the two grooves, and two threaded blocks are provided on the external thread sleeve of the bidirectional threaded rod, and the two threaded blocks are slidably connected to the inner wall of the groove, and one end of the four threaded blocks away from the inner wall of the groove is rotatably connected to a deflection plate, and one end of the four deflection plates away from the threaded blocks are rotatably connected to two negative pressure plates respectively, and a motor is fixedly connected outside the box body, and the driving shaft of the motor rotates through the box body and is coaxially fixedly connected to one of the bidirectional threaded rods, and one end of the two bidirectional threaded rods rotates through the box body and is connected through transmission mechanism.
[0009] Furthermore, the transmission mechanism includes two pulleys, the two pulleys are connected by a synchronous belt transmission, and the two pulleys are coaxially fixedly connected to two bidirectional threaded rods respectively.
[0010] Furthermore, the fixing claw is arranged in an arc shape, and the fixing claw is rotationally connected to the placement plate through a torsion bearing. The multiple fixing claws located on the same side of the placement groove are distributed in an array, and the multiple fixing claws located on both sides of the placement groove are staggered.
[0011] Furthermore, an arc-shaped groove is provided below one side of the negative pressure plate close to the placement plate, and the arc-shaped groove matches the fixing claw.
[0012] Furthermore, the side walls of the box body at both ends of the placement plate are transparent.
[0013] Furthermore, ultraviolet lamps are installed on the inner side walls of the box located at both ends of the placement plate.
[0014] Compared with the prior art, the beneficial effects of the present invention are at least:
[0015] 1. By setting a motor and a negative pressure plate, the motor drives the negative pressure plate to move slowly, so that the air pressure between the two negative pressure plates is reduced. In the process of continuous decompression, if the medical device is tightly packed, the packaging bag will expand violently under the action of air pressure. When the low air pressure reaches a certain critical value, the packaging bag will be damaged and leak. At this time, it can be detected that the current medical device packaging bag has good sealing performance; if the medical device packaging has leaked, the gas in the packaging bag will be pressed into the box body under the action of air pressure, so that the air pressure in the packaging bag is equivalent to the air pressure in the box body. At this time, the packaging bag will not produce violent collisions and will not be broken. At this time, the current medical device packaging bag leakage can be detected, and the sealing test of the medical device packaging is more intuitive;
[0016] 2. By setting fixed claws, when the packaging bag expands to the point of being damaged, the gas inside the packaging bag will quickly overflow and push the medical device to deviate. At this time, the fixed claws can limit the medical device to prevent the medical device from colliding with the inner wall of the box, thus protecting the medical device during detection.
[0017] The utility model is more intuitive in detecting the sealing property of medical device packaging and can protect the medical device during the detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.
[0028] Example 1: Please refer to Figures 1 to 7 , a medical device testing device for medical testing, including a box body 1. It should be noted that the side walls of the box body 1 at both ends of the placement plate 3 are transparent. It should be noted that the transparent setting can intuitively observe the shape changes of the medical device packaging bag, which is convenient for judging its sealing. Please refer to Figure 7, the upper sealing cover of the box body 1 is provided with a sealing cover 2. It should be noted that the sealing cover 2 and the box body 1 are both provided with steps, and the steps are provided with sealing protrusions to improve the sealing between the sealing cover 2 and the box body 1. A placement plate 3 is fixedly installed in the middle part of the bottom of the box body 1, and a placement groove 4 is provided on the upper end surface of the placement plate 3. It should be noted that the placement groove 4 is convenient for placing medical devices. When fixing and testing, it can cause a certain resistance to the medical devices to prevent them from moving. The parts of the placement plate 3 located on both sides of the placement groove 4 are installed with multiple fixing claws 5. It should be noted that the fixing claws 5 are arranged in an arc shape, and the fixing claws 5 are rotatably connected to the placement plate 3 through a torsion bearing. The multiple fixing claws 5 located on the same side of the placement groove 4 are distributed in an array, and the multiple fixing claws 5 located on both sides of the placement groove 4 are staggered. It should be noted that the multiple fixing claws 5 can hold the medical device tightly to prevent it from moving. Please refer to Figure 6 Two negative pressure plates 6 are sealed and slidably connected in the box body 1. Furthermore, an arc-shaped groove 16 is provided below the negative pressure plate 6 on one side close to the placement plate 3. The arc-shaped groove 16 matches the fixing claw 5. It should be noted that the arc-shaped groove 16 can reduce the space inside the box body 1 as much as possible, reduce the air content inside the box body, and increase the upper limit of negative pressure.
[0029] In this embodiment, the box body 1 is provided with an adjustment mechanism 7 for adjusting the two negative pressure plates 6. Specifically, the adjustment mechanism 7 includes two grooves 8 arranged on the inner wall of the box body 1, and the two grooves 8 are rotatably connected with a bidirectional threaded rod 9. The two-way threaded rod 9 is externally threaded with two threaded blocks 10. It should be noted that the two threaded blocks 10 located outside the same bidirectional threaded rod 9 are provided with threaded holes matching the bidirectional threaded rod 9, and the threads in the two threaded holes are rotated in opposite directions. The two threaded blocks 10 are slidably connected to the inner wall of the groove 8, and the ends of the four threaded blocks 10 away from the inner wall of the groove 8 are rotatably connected with a deflection plate 11. It should be noted that the deflection plate 1 1 is arranged in a plate shape. When the threaded block 10 moves, the deflection plate 11 will be driven to deflect, and the deflection plate 11 can push and pull the negative pressure plate 6. The ends of the four deflection plates 11 away from the threaded block 10 are respectively rotatably connected to the two negative pressure plates 6. A motor 12 is fixedly connected to the outside of the box body 1. The driving shaft of the motor 12 rotates through the box body 1 and is coaxially fixedly connected to one of the two-way threaded rods 9. One ends of the two two-way threaded rods 9 rotate through the box body 1 and are connected through a transmission mechanism 13. It should be noted that the transmission mechanism 13 includes two pulleys 14, which are connected by a synchronous belt transmission, and the two pulleys 14 are respectively coaxially fixedly connected to the two two-way threaded rods 9.
[0030] When the sealing of medical device packaging is tested in this embodiment, the sealing cover 2 is opened, and the well-packaged medical device is placed on the placement plate 3 and fixed by multiple fixing claws 5. Then, the two bidirectional threaded rods 9 are driven to rotate by the motor 12. The two bidirectional threaded rods 9 drive the four threaded blocks 10 to move relatively. The four threaded blocks 10 drive the two negative pressure plates 6 to move relatively through the four deflection plates 11 until the two negative pressure plates 6 are in contact with each other. At this time, the sealing cover 2 is covered, and then the motor 12 is rotated in the opposite direction to drive the two negative pressure plates 6 to move away. During the process of moving away, the air pressure in the box body 1 becomes smaller, and the sealing of the medical device packaging can be tested. When the sealing is good, the packaging bag will expand under the action of air pressure, and when a certain critical value is reached, the packaging bag will be damaged; when the sealing is poor, the gas in the packaging bag will overflow under the action of air pressure, and the packaging bag will not expand excessively and will not be damaged.
[0031] Example 2: Please refer to Figure 8 , a medical device detection equipment for medical detection, which is different from Example 1 in that ultraviolet lamps 15 are installed on the inner walls of the box 1 at both ends of the placement plate 3.
[0032] In this embodiment, when testing the sealing performance of medical device packaging, if it is found that the sealing performance of the packaging bag is poor, the medical device can be irradiated with two ultraviolet lamps 15 to sterilize and disinfect it.
[0033] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0034] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
