Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies disinfection, and in particular to a medical supplies disinfection device. Background Art

[0002] Disinfection of medical supplies includes physical and chemical methods. Items must be cleaned before disinfection to ensure that the concentration and contact time of the disinfectant meet the requirements. Pay attention to safety during use to avoid damage to the items. Disinfected medical supplies should be properly packaged and stored to prevent secondary contamination, ensure their sterility, and avoid the spread of infection.

[0003] There are many types of disinfection devices in the prior art, such as a medical supply disinfection device disclosed in publication number CN118542955B. This device achieves comprehensive disinfection and improves the disinfection effect by laying the medical supplies flat inside a mesh frame and controlling the forward rotation of the drive motor to drive the medical supplies to rotate at a constant speed inside the disinfection box. However, this device has certain problems during the disinfection process: the parts of the medical supplies that are in contact with the mesh frame cannot directly come into contact with the steam, resulting in incomplete disinfection of these areas. In addition, existing devices usually improve the disinfection effect by allowing the medical supplies to move during the disinfection process, but this method may cause collisions between medical items, and during the driving rotation or shaking process, the position of the medical supplies may change, thereby affecting the steam injection angle, resulting in the steam being unable to effectively inject into all parts of the medical supplies, which may still result in incomplete disinfection. Therefore, existing devices have certain limitations in disinfection effect and are in urgent need of improvement. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a medical supply disinfection device that can effectively solve the problems in the prior art that the parts of the medical supplies that contact the disinfection device cannot be disinfected, and that the medical supplies deviate from the steam injection angle during the process of being driven to move and shake, resulting in low disinfection efficiency.

[0017] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0018] First, when the rotating nozzle begins to spray steam to disinfect the medical supplies placed in the first and second supporting circular frames, the positions of the first and second supporting circular frames are driven by the linear drive device to be just above the electromagnetic block. At this time, the rotary drive component drives the first and second supporting circular frames to rotate intermittently. The repulsive force generated by the electromagnetic block pushes the magnetic lifting plate at the bottom of the second supporting circular frame to rise. The rotating nozzles installed on both sides will rotate downward due to gravity to spray the medical supplies at the bottom of the second supporting circular frame. The rotating nozzles in the horizontal state are: the rotating nozzle above the horizontal partition will be flush with the horizontal partition and spray the medical supplies. The rotating nozzle below the horizontal partition will maintain a 90° rotation angle to spray and disinfect the medical supplies. The state of the rotating nozzle above the second supporting circular frame is: the rotating nozzle and the partition remain vertically parallel to each other and spray and disinfect the medical supplies above the horizontal partition.

[0019] Second, water is transported into the water tank through a connecting pipe and cleaning water is sprayed out from the nozzle. The cleaning water will come into contact with the medical supplies and clean them. As the medical supplies are continuously driven to rotate, the cleaning water will clean away the dirt attached to the outer surface of the medical supplies. This can effectively disinfect the places where the dirt and medical supplies are attached during subsequent steam spray disinfection.

[0020] Third, the connecting rod driven to lift and lower drives the lifting plate to lift and lower on the inner wall of the pressure relief barrel. When the lifting plate rises, the air in the sterilization box will enter between the lifting plate and the bottom plate through the first one-way valve. When the lifting plate descends, the air between the lifting plate and the bottom plate will be ejected outward from the second one-way valve. In the process of the lifting plate lifting and lowering back and forth, the air in the sterilization box is drawn out, so that the sterilization box is in a negative pressure state, which can reduce the interference of air on steam penetration. By establishing a negative pressure environment, steam can quickly and thoroughly enter all gaps in medical supplies, especially some tiny holes or dead corners. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments 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.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example: Refer to Figures 1 to 10 , a medical supplies disinfection device, comprising:

[0036] A sterilizing box 1 is provided with a sealed door 2 which is slidably mounted on the other side of the sterilizing box 1 in an airtight manner. A cleaning area and a sterilizing area are provided in the sterilizing box 1.

[0037] The driving bearing assembly 3 includes a first bearing circular frame 305 arranged in the disinfection box 1. The inner wall of the first bearing circular frame 305 is airtightly rotatably mounted with a second bearing circular frame 309. A plurality of partitions 315 are evenly mounted inside the second bearing circular frame 309. Each partition 315 divides the second bearing circular frame 309 into a plurality of disinfection areas. A magnetic lifting plate 318 is elastically and slidably mounted in the partition 315. A plurality of rotating nozzles 319 are rotatably mounted on both sides of the magnetic lifting plate 318. An electromagnetic block 325 is fixedly mounted at the bottom end of the disinfection box 1 and at a position away from the first bearing circular frame 305. A single medical supply is placed in the disinfection area. A partition 315 prevents the medical supplies from colliding with each other. The electromagnetic block 325 drives the magnetic lift plate 318 at the bottom of the second supporting circular frame 309 to slide upward, allowing the rotating nozzle 319 to rotate downward to spray disinfectant on the medical supply. Each time the first supporting circular frame 305 and the second supporting circular frame 309 are driven to rotate, each rotating nozzle 319 can rotate to spray disinfectant on the medical supply placed in the second supporting circular frame 309, ensuring that the steam sprayed by the rotating nozzle 319 can effectively disinfect the medical supply.

[0038] The pressure relief component 5 is used to discharge the air inside the sterilization box 1 to reduce the air pressure;

[0039] The jet disinfection assembly 6 is used to disinfect the disinfection area and the second supporting circular frame 309 by inputting steam.

[0040] Reference Figures 2 to 5Two pairs of sealing plates 301 are symmetrically installed on both sides of the disinfection box 1. A linear drive device 302 is embedded in each pair of sealing plates 301. The linear drive device 302 is electrically connected to the controller 7. A connecting piece 303 is fixedly installed on the driving end of the linear drive device 302. One end of the connecting piece 303 passes through the disinfection box 1 and is rotatably installed with a gear ring 304. The inner wall of the gear ring 304 is fixedly connected to the first bearing circular frame 305. The outer wall of the first bearing circular frame 305 is provided with a first connecting hole 323, and the inner wall of the second bearing circular frame 309 is provided with a second connecting hole 324. One side of the first bearing circular frame 305 is fixedly installed. There is a first electromagnet 321, and two second electromagnets 322 are equidistantly installed on one side of the second bearing circular frame 309. The first electromagnet 321, the second electromagnet 322 and the controller 7 are electrically connected. A round cover 310 is airtightly slidably installed on one side of the second bearing circular frame 309. A hollow main shaft 308 is rotatably installed in the second bearing circular frame 309. The hollow main shaft 308 passes through the first bearing circular frame 305 and extends to one side thereof. The outer wall of the hollow main shaft 308 is connected to the partition 315. A slide groove is opened in the partition 315. The inner wall of the slide groove is slidably connected to the magnetic lifting plate 318. Each rotating nozzle 319 The upper end is connected with a connecting hose 320, a first spring 317 is fixedly installed between the magnetic lifting plate 318 and the slide, an output pipe 316 is fixedly installed on the inner wall of the slide, the magnetic lifting plate 318 is slidably connected to the outer wall of the output pipe 316, the connecting hose 320 passes through the partition 315 and is connected to the output pipe 316, the output pipe 316 passes through the partition 315 and is connected to the hollow main shaft 308, the outer wall of the hollow main shaft 308 and is provided with a rotating connecting sleeve 312 on one side of the first bearing circular frame 305, the outer wall of the rotating connecting sleeve 312 is symmetrically provided with two hollow tubes 313, the hollow tube 313 passes through the rotating connecting sleeve The sleeve 312 is connected to the hollow main shaft 308, and a joint 314 is fixedly installed at one end of the hollow tube 313. When the first supporting circular frame 305 and the second supporting circular frame 309 are driven to rotate, the round cover 310 can close the second supporting circular frame 309 to prevent steam leakage. At the same time, after the medical supplies are cleaned, the first steam sterilization can allow the steam in the sterilization box 1 to reach a relatively high temperature and humidity level. When steam is sprayed into the second supporting circular frame 309 for the second time, the medical supplies will be heated in a concentrated and directionally manner, which helps to improve the disinfection effect on the surface and interior of the items.

[0041] Reference Figure 4A U-shaped frame 306 is fixedly installed on one side of the connecting member 303, and a rotating drive member 307 is fixedly installed on one side of the U-shaped frame 306. The rotating drive member 307 can be used with an existing stepper motor. The stepper motor is an electric motor that performs precise position control through electric pulse control. Unlike traditional DC motors or AC motors, the rotation of the stepper motor is achieved through "stepping" motion at a fixed angle. The output end of the rotating drive member 307 passes through the U-shaped frame 306 and is fixedly connected to the hollow main shaft 308. A pressure valve 311 is embedded on one side of the first bearing circular frame 305, and the outer wall of the hollow tube 313 is fixedly connected to both sides of the U-shaped frame 306. The stepper motor can drive the second bearing circular frame 309 to rotate intermittently to drive the medical supplies to rotate intermittently.

[0042] Reference Figures 1 to 2 , also includes a spray cleaning component 4, the spray cleaning component 4 includes a water tank 401 fixedly installed on the upper end surface of the disinfection box 1, a connecting pipe 403 is fixedly installed on the upper end surface of the water tank 401, the connecting pipe 403 is connected to an external water source, and a plurality of nozzles 402 are evenly installed on the lower end surface of the water tank 401, and a plurality of drain outlets 404 are fixedly installed on one side of the disinfection box 1 and at a lower position.

[0043] Reference Figures 6 and 7 , the inner top of the disinfection box 1 is fixedly installed with a mounting block 501, and a transmission rod 502 is rotatably installed in the mounting block 501. A tooth head 513 is fixedly installed on one end of the transmission rod 502, and the tooth head 513 is engaged with the gear ring 304. A reciprocating screw rod 504 is rotatably installed on the upper end surface of the disinfection box 1. The lower end of the reciprocating screw rod 504 passes through the disinfection box 1 and is fixedly installed with a rotating short shaft 503. The rotating short shaft 503 is rotatably connected to the disinfection box 1. The rotating short shaft 503 and the transmission rod 502 are driven by a bevel gear pair. The outer wall of the reciprocating screw rod 504 is provided with a rotating sleeve 505 that matches it. Two connecting rods 506 are symmetrically installed on the outer wall of the rotating sleeve 505. The upper end surface of the disinfection box 1 A pressure relief barrel 507 is fixedly installed at a position close to the controller 7, a bottom plate 508 is fixedly installed on the inner bottom end of the pressure relief barrel 507, a first one-way valve 509 is embedded in the bottom plate 508, a lifting plate 511 is airtightly slidably installed in the pressure relief barrel 507, a second one-way valve 512 is embedded in the lifting plate 511, a second spring 510 is fixedly installed between the lifting plate 511 and the bottom plate 508, and the connecting rod 506 is fixedly connected to the lifting plate 511. By discharging the air from the disinfection box 1 and reducing the air pressure in the disinfection box 1, the air has a significant impact on the steam sterilization process. The air not only affects the heating efficiency of the steam, but may also hinder the penetration of the steam, resulting in incomplete sterilization effect.

[0044] Reference Figures 8 and 9A support plate 601 is fixedly installed on the side of the disinfection box 1 away from the sealed door 2, and a steam generator 602 is fixedly installed on the upper end surface of the support plate 601. Two steam nozzles 605 are symmetrically installed on the inner wall of the disinfection box 1 and at a position away from the sealed door 2. The two steam nozzles 605 are connected to a second solenoid valve 606 on the opposite side. The second solenoid valve 606 is electrically connected to the controller 7. The second solenoid valve 606 and the steam generator 602 are connected through a pipeline. Two connecting plates 603 are symmetrically installed on the inner wall of the disinfection box 1 and at the position of the steam nozzle 605. The upper ends of the two connecting plates 603 are connected to a first solenoid valve 604. The first solenoid valve 604 and the steam generator 602 are connected through a pipe. The connecting plate 603 is provided with a card slot 607, and a trigger sensor 608 is fixedly installed in the card slot 607. The first solenoid valve 604, the trigger sensor 608 and the controller 7 are electrically connected. The second solenoid valve 606 and the first solenoid valve 604 are an automatic control element that uses electromagnetic principles to control the flow of fluid. It controls the opening and closing of the valve by the action of the electromagnetic coil and the on-off of the current, thereby realizing the control of the fluid in the pipeline system. The trigger sensor 608 is a prior art. The trigger sensor 608 is a sensor for detecting a certain specific condition or event and sending a signal. It triggers a corresponding response or control operation by sensing changes in the external environment or objects.

[0045] The working principle of the present invention is as follows:

[0046] First, clean the medical supplies: open the sealed door 2, then open the round cover 310, and place the medical items that need to be cleaned and disinfected into the second carrying round frame 309. The partition 315 divides the second carrying round frame 309 into four independent spaces, so as to load the medical supplies (with attached Figure 4Taking the four partitions 315 in the middle as an example), close the sealing door 2 and install the round cover 310 back to its original position, turn on the rotary drive member 307 through the controller 7, drive the hollow main shaft 308 to rotate, and the rotating hollow main shaft 308 will drive the second supporting circular frame 309 to rotate. The controller 7 will control the input voltage of the first electromagnet 321 to enhance the magnetic force and adsorption with the second electromagnet 322, so that during the rotation of the second supporting circular frame 309, the first supporting circular frame 305 will be driven to rotate together, and the rotating second supporting circular frame 309 and the first supporting circular frame 305 will drive the medical supplies together. As the medical supplies rotate together, the partition 315 provided can effectively prevent collisions between each other. Water is transported to the water tank 401 through the connecting pipe 403 connected to an external water source, and cleaning water is sprayed out from the nozzle 402. The cleaning water enters the second supporting circular frame 309 through the first connecting hole 323 and the second connecting hole 324, and contacts and cleans the medical supplies. As the medical supplies are continuously driven to rotate, the cleaning water cleans away dirt attached to the outer surface of the medical supplies. This can effectively prevent the areas where dirt and medical supplies are attached from being thoroughly disinfected during subsequent steam spray disinfection.

[0047] Second, reduce the air pressure in the disinfection box 1: when the first bearing circular frame 305 is driven to rotate, the first bearing circular frame 305 will drive the gear ring 304 to mesh with the tooth head 513 and drive the tooth head 513 and the transmission rod 502 to rotate. The rotating transmission rod 502 drives the rotating short shaft 503 and the reciprocating screw rod 504 to rotate through the bevel gear pair. The rotating reciprocating screw rod 504 drives the rotating sleeve 505 and the connecting rod 506 to rise and fall. The lifting connecting rod 506 drives the lifting plate 511 to rise and fall on the inner wall of the pressure relief barrel 507 and stretch the second spring 510. When the lifting plate 511 rises, the air in the disinfection box 1 will pass through The steam passes through the first one-way valve 509 and enters between the lifting plate 511 and the bottom plate 508. When the lifting plate 511 descends, the air between the lifting plate 511 and the bottom plate 508 will be ejected outward from the second one-way valve 512. In the process of the lifting plate 511 being driven to lift and lower, the air in the sterilization box 1 will also be continuously drawn out, thereby reducing the air in the sterilization box 1 and lowering the air pressure, so that the sterilization box 1 is in a negative pressure state, which can reduce the interference of air on steam penetration. By establishing a negative pressure environment, steam can quickly and thoroughly enter all gaps in medical supplies, especially some tiny holes or blind spots.

[0048] Third, disinfect the medical supplies: the controller 7 controls the linear drive device 302 to drive the connector 303 to move the first carrier circular frame 305 and the second carrier circular frame 309, and moves the first carrier circular frame 305 and the second carrier circular frame 309 from the cleaning area to the disinfection area. The controller 7 turns on the steam generator 602, and the steam generated by the steam generator 602 is transported to the steam nozzle 605 through the pipeline and sprayed to perform the first disinfection of the first carrier circular frame 305, the second carrier circular frame 309 and the medical supplies. Such comprehensive disinfection can prevent viruses from adhering to the disinfection tools, and reduce the disinfection effect when the medical supplies are taken out later. After the steam nozzle 605 continues to spray steam for disinfection for a period of time, the controller 7 controls the linear drive device 302 to drive the first carrier circular frame 305 and the second carrier circular frame 309 to move. At this time, the connector 314 will slide in contact with the card slot 607 and contact with the trigger sensor 608. The trigger sensor 608 will control the second solenoid valve 606 through the controller. The first solenoid valve 604 is closed and opened, and the steam generated by the steam generator 602 is input into the connecting plate 603 through the pipeline, and then enters the hollow tube 313 through the joint 314, and finally enters the hollow main shaft 308 through the rotating connecting sleeve 312. The steam entering the hollow main shaft 308 is ejected from the rotating nozzle 319 through the output pipe 316 and the connecting hose 320 to perform a second jet disinfection on the medical supplies placed in various areas of the second supporting circular frame 309. It should be noted that the controller 7 disconnects the voltage input to the first electromagnet 321 to make the first electromagnet 321 lose its magnetic force. In this way, during the rotation of the second supporting circular frame 309, the second supporting circular frame 309 will drive the second connecting hole 324 to stagger with the first connecting hole 323. After the second connecting hole 324 is staggered with the first connecting hole 323, the controller 7 will re-control the voltage input to the first electromagnet 321 to enhance the magnetic force of the first electromagnet 321 and adsorb it to the other first electromagnet 321 (see attached Figure 2 ), so that the second connecting hole 324 and the first connecting hole 323 are completely staggered, so that the second supporting circular frame 309 remains sealed. The two first electromagnets 321 after adsorption will re-synchronize and rotate with the first supporting circular frame 305 and the second supporting circular frame 309. During the periodic rotation of the first supporting circular frame 305 and the second supporting circular frame 309, the voltage controlled by the controller 7 to the first electromagnet 321 is always maintained;

[0049] It should also be noted that when the rotating nozzle 319 begins to spray steam for disinfection, the positions of the first supporting circular frame 305 and the second supporting circular frame 309 are driven by the linear drive device 302 to above the electromagnetic block 325. At this time, the rotary drive member 307 drives the first supporting circular frame 305 and the second supporting circular frame 309 to rotate intermittently. Each rotation causes the partition 315 to be in a cross state within the second supporting circular frame 309. The jet angles of the magnetic lifting plates 318 are as follows:

[0050] The rotating nozzle 319 at the bottom is in the following state: the repulsive force generated by the electromagnetic block 325 pushes the magnetic lifting plate 318 at the bottom of the second supporting circular frame 309 upward. After the magnetic lifting plate 318 rises, the rotating nozzles 319 rotatably mounted on both sides rotate downward due to gravity to spray the medical supplies at the bottom of the second supporting circular frame 309 (the medical supplies will naturally rotate to the bottom of the second supporting circular frame 309 due to their own weight).

[0051] The rotating nozzle 319 located horizontally within the second supporting circular frame 309 is in the following state: the medical supplies will be located above the horizontal partition 315 due to their own gravity. The rotating nozzle 319 located above the horizontal partition 315 will be flush with the horizontal partition 315 to spray air to the medical supplies located above the horizontal partition 315. The rotating nozzle 319 located below the horizontal partition 315 will naturally rotate due to its own gravity and maintain a 90° rotation angle with the horizontal partition 315 to spray air to disinfect the medical supplies.

[0052] The rotating nozzle 319 located above the second supporting circular frame 309 is in a state where the rotating nozzle 319 is kept vertically parallel to the partition 315 to spray and disinfect the medical supplies above the horizontal partition 315.

[0053] The above is as attached Figure 10 As shown;

[0054] According to the above, the medical supplies in each area of the second carrying circular frame 309 are spray-sterilized. During the periodic and continuous intermittent rotation of the second carrying circular frame 309 and the continuous spray-sterilization process of the rotating nozzle 319, the medical supplies can be continuously rotated in the second carrying circular frame 309 to sterilize the entire medical supplies, avoiding unsterilized areas and incomplete disinfection. The pressure valve 311 can discharge the pressure outward after the air pressure in the second carrying circular frame 309 increases to a certain level, avoiding excessive air pressure in the second carrying circular frame 309.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
