Description

[0002] Medical devices refer to various equipment, instruments, appliances and software used for diagnosis, treatment, monitoring, disease prevention or improvement of health. These devices are widely used in hospitals, clinics, home care and other places, and medical devices usually need to be disinfected after use. Medical device disinfection is an important step to ensure that medical equipment and instruments are sterile before use. Its main purpose is to prevent infection and cross infection and protect the health of patients and medical staff. It is necessary to disinfect and sterilize medical devices after use by a disinfection and sterilization device. For example, a medical device sterilization and disinfection device disclosed in application number CN202410302241.5 provides a device for disinfecting medical devices using high-temperature steam.

[0003] Existing sterilization and disinfection devices for medical instruments in boxes, such as surgical instrument boxes, dental instrument sterilization boxes, etc., usually sterilize medical instruments at a continuous temperature and a continuous gas output volume, and cannot automatically adjust to the required gas volume and gas temperature according to the weight and length of the medical instruments, which ultimately leads to unsatisfactory disinfection effects and low efficiency. For example, for larger or heavier boxes, if the gas volume is fixed, it may not cover every corner inside the box, resulting in incomplete sterilization, and there may be blind spots or dead corners for gas flow in different parts of the instruments or boxes. If the gas volume is insufficient or the temperature is not suitable, these areas may not be fully sterilized, leaving potential sources of infection. Summary of the invention

The exhaust pump 23 is started to recover the steam through the steam recovery device 22, and then the recovered steam is discharged into the steam ejector 21 through the exhaust pipe 25 for recycling.

[0021] It can be adaptively adjusted according to the medical devices that need to be disinfected. The following structure is used specifically. Figures 2 to 6 , the adaptive adjustment mechanism 3 includes a placement plate 31 elastically slidably connected to the inner wall of the cabinet 1, the outer wall of the placement plate 31 is connected to a first sliding rheostat, the sliding rheostat is electrically connected to the steam ejector 21 and the external power supply to form a first adjustment loop, the top of the placement plate 31 is slidably connected to two symmetrical extrusion plates 32, the outer walls of the two extrusion plates 32 are both connected to second sliding rheostats, the second sliding rheostats are electrically connected to a current measuring instrument, the second sliding rheostat, the current measuring instrument, the steam recovery device 22 and the external power supply are electrically connected to a PLC controller to form a second adjustment loop, the adaptive adjustment mechanism 3 also includes a passive adjustment component 33, the passive adjustment component 33 is used to control the height of steam ejected by the steam ejector 21; The adaptive adjustment mechanism 3 also includes a sliding groove 34 opened on the inner wall of the cabinet 1.

The second sliding rheostat includes a second resistor plate 311 and a second conductive sheet 312, and the second conductive sheet 312 is in sliding contact with the second resistor plate 311. The inner wall of the cabinet 1 is fixedly connected to the second resistor plate 311, and the side of the extrusion plate 32 close to the second resistor plate 311 is fixedly connected to the second conductive sheet 312. When the second conductive sheet 312 moves from the surface of the second resistor plate 311 to the branch line in the cabinet 1, the resistance of the second sliding rheostat in the second regulating loop gradually increases.

[0023] The passive adjustment component 33 includes a ventilation groove 331 opened inside the placement plate 31, and a plurality of air outlets 332 are symmetrically opened at the top of the placement plate 31 along the center line of the placement plate 31, and the inner walls of the plurality of air outlets 332 are opened with expansion grooves 333, and the inner walls of the expansion grooves 333 are slidably connected with wind shield plates 334, and the bottom end of the placement plate 31 is opened with an air inlet 3316 connected with the ventilation groove 331.

[0024] The inner walls of both sides of the cabinet 1 are provided with movable grooves 335, and the outer wall of the placement plate 31 is provided with a transmission hole 336 that communicates with the movable grooves 335 and the ventilation grooves 331. The inner walls of the two movable grooves 335 are slidably connected with a tooth plate 337 that is fixedly connected to the inner wall of the placement plate 31, and the tooth plate 337 is fixedly connected to the sliding plate 37. The inner wall of the ventilation groove 331 is fixedly connected with two symmetrical support plates 338. The inner walls of the two movable grooves 335 are rotatably connected with threaded rods 339, and the other ends of the threaded rods 339 are rotatably connected to the outer wall of one of the support plates 338. The outer wall of 339 is fixedly connected with a gear 3310 meshing with the tooth plate 337, the inner wall of the ventilation slot 331 is fixedly connected with two symmetrical limit rods 3311, and the other ends of the two limit rods 3311 are respectively fixedly connected with the outer walls of the other two sides of another support plate 338, the outer walls of the two threaded rods 339 are threadedly sleeved with a plurality of connecting plates 3312, the other ends of the connecting plates 3312 are slidably connected with the limit rods 3311, the top of the connecting plates 3312 is fixedly connected with a plurality of vertical plates 3313 fixedly connected with the wind shield 334, and the threads of the two threaded rods 339 are opposite.

[0025] An inverted Y-shaped slide 3314 is provided on the inner wall of the cabinet 1. The inverted Y-shaped slide 3314 consists of a vertical section and an inclined section symmetrically inclined downward and connected to the vertical section. The depth of the inclined section in the downward extending direction is linearly shortened until it is flush with the inner wall surface of the cabinet 1. The two extrusion plates 32 are fixedly connected to one side of the inverted Y-shaped slide 3314 with an elastic telescopic rod 3315 in sliding contact with the Y-shaped slide. When the disinfection of the medical device is about to be completed, the steam will push the two telescopic plates 39 to continue to move upward, and further drive the elastic telescopic rod 3315 to enter the vertical section of the inverted Y-shaped slide 3314 through the extrusion plate 32 to take out the disinfected medical device. Since there is no steam to blow the telescopic plate 39 upward after the disinfection of the medical device is completed, the telescopic plate 39 and the extrusion plate 32 will slowly move downward under their own gravity, causing the elastic telescopic rod 3315 to move downward. Since the depth of the inclined section of the inverted Y-shaped slide 3314 in the downward extension direction is linearly shortened until it is flush with the inner wall of the cabinet 1, the extrusion plate 32 is driven by the elastic telescopic rod 3315 to slowly restore to its initial state, and the two extrusion plates 32 are supported and fixed by the horizontal plate 5.

[0026] Two symmetrical reset springs 4 are fixedly connected to the inner wall of the cabinet 1, and the other end of the reset spring 4 is fixedly connected to a horizontal plate 5 that contacts the extrusion plate 32 at the corresponding position. A connecting spring is fixedly connected between the placement plate 31 and the steam ejector 21, and the connecting spring can help the placement plate 31 to reset automatically.

[0027] The working principle of the present invention is as follows: First, the cabinet 1 needs to be opened, and then the medical device to be sterilized is placed inside the cabinet 1. The placement process is as follows: the medical device to be sterilized is placed on the placement plate 31 and pushed into the cabinet 1. During the pushing process, the horizontal plate 5 will be pressed inward until the medical device to be sterilized is squeezed into the cabinet 1. At this time, the horizontal plate 5 is no longer in contact with the squeezing plate 32. The elastic force of the spring column 38 is released, driving the two squeezing plates 32 to squeeze the medical device to be sterilized, thereby driving the second conductive sheet 312 to move on the surface of the second resistor plate 311 toward the cabinet 1. At the same time, due to the weight of the sterilized medical device, the placement plate 31 will be pressed downward, further driving the first conductive sheet 35 to slide downward on the surface of the first resistor plate 36. After the first conductive sheet 35 slides downward on the surface of the first resistor plate 36, since the first sliding rheostat is electrically connected to the steam ejector 21, the longer the distance that the placement plate 31 drives the first conductive sheet 35 to move downward, the heavier the weight of the medical device to be sterilized is, and therefore the greater the current flowing into the steam ejector 21, the greater the working power of the steam ejector 21, and thus the greater the amount of steam ejected and the higher the temperature, the ejected steam passes through the air inlet 3316 to eject the steam ejected from the steam ejector 21 into the ventilation slot 331, and then the steam is sprayed on the surface of the medical device to be sterilized through the air outlet 332, so as to sterilize the medical device to be sterilized; During the sliding of the second conductive sheet 312 on the second resistor plate 311, since the second sliding rheostat, the current measuring instrument, the steam ejector 21 and the external power supply electrical signal are connected to the PLC controller, the current in the second regulating loop is detected by the current measuring instrument, and the detected electrical signal is transmitted to the PLC controller. The PLC controller determines the magnitude of the generated current to further control the steam ejector 21, the amount of steam ejected and the temperature. For example, the closer the second conductive sheet 312 is to the branch line in the cabinet 1 after the two second conductive sheets 312 move, the shorter the length of the medical device to be sterilized. Therefore, it is necessary to further control the amount of steam ejected by the steam ejector 21 to be smaller and the steam temperature to be lowered. Conversely, the amount of steam ejected by the steam ejector 21 is further controlled to be larger and the steam temperature to be higher. Therefore, the amount of steam ejected by the steam ejector 21 and the steam temperature are further controlled by the PLC controller, and further disinfection is performed according to the length of the medical device.

[0028] In the process of sterilizing medical devices by steam, the surface of the medical devices to be sterilized is slowly sterilized by steam, and at the same time, the steam will push the telescopic plate 39 upward. In the initial state, the telescopic plate 39 can trap the steam under the telescopic plate 39 to better sterilize the medical devices. Then, due to the increase in the amount of steam, the telescopic plate 39 will be slowly pushed to move upward, thereby driving the sliding plate 37 to move synchronously, and the sliding plate 37 will further drive the toothed plate 337 to move upward, thereby causing the gear 3310 to rotate. The rotation of the gear 3310 will drive the threaded rod 339 to rotate, and the limiting rod 3311 will limit the connecting plate 3312 so that the connecting plate 3312 can be on the surface of the threaded rod 339. Movement, since the threads of the two threaded rods 339 are opposite, the two threaded rods 339 drive the connecting plate 3312 to move in opposite directions, and the movement of the connecting plate 3312 drives the wind shield 334 to slowly block the air outlet 332. Since the air outlet 332 gradually becomes smaller, and the amount of steam sprayed by the steam ejector 21 remains unchanged, the greater the pressure of the steam sprayed from the air outlet 332, the higher the position of the medical device that needs to be sterilized, and at the same time, it will push the telescopic plate 39 to move upward, thereby slowly adjusting the size of the air outlet 332, until the medical device that needs to be sterilized is fully sterilized, and the extrusion plate 32 is separated from the medical device that needs to be sterilized, indicating that the sterilization is completed.
