Description

Technical Field

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

[0002] The disinfection of medical supplies includes physical methods and chemical methods. Before disinfection, the items need to be cleaned 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. The disinfected medical supplies should be properly packaged and stored to prevent secondary contamination, ensure their sterile state, and avoid the spread of infection.

[0003] There are various disinfection devices in the prior art. For example, a disinfection device for medical supplies disclosed in the patent with publication number CN118542955B. This device spreads medical supplies flat inside a mesh frame and controls the forward rotation of a driving motor to drive the medical supplies to rotate uniformly in the disinfection chamber, thereby achieving comprehensive disinfection and improving the disinfection effect. However, there are certain problems in the disinfection process of this device: The parts of the medical supplies in contact with the mesh frame cannot directly contact the steam, resulting in incomplete disinfection in these areas. In addition, existing devices usually improve the disinfection effect by moving the medical supplies during the disinfection process. However, this method may cause collisions between medical items, and during the driving rotation or shaking process, the positions of the medical supplies may change, thus affecting the steam injection angle and causing the steam to be unable to effectively spray onto all parts of the medical supplies, which may still result in incomplete disinfection. Therefore, there are certain limitations in the disinfection effect of existing devices and they need to be improved urgently. Summary of the Invention

[0012] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: First, when the rotating nozzle starts to spray steam to disinfect the medical supplies arranged in the first and second carrying circular frames, the positions of the first and second carrying circular frames will be driven by the linear driving device to be just above the electromagnetic block. At this time, the rotating driving member will drive the first and second carrying circular frames to rotate intermittently. The repulsive force generated by the electromagnetic block will push the magnetic lifting plate located at the lower part in the second carrying circular frame to rise. The rotating nozzles rotatably installed on both sides will rotate downward by gravity to spray air on the medical supplies at the bottommost part in the second carrying circular frame. The rotating nozzles in the horizontal state are as follows: the rotating nozzles above the horizontal partition will be flush with the horizontal partition to spray air on the medical supplies, and the rotating nozzles below the horizontal partition will maintain a 90° rotation angle to spray and disinfect the medical supplies. The state of the rotating nozzles above the second carrying circular frame is that the rotating nozzles are perpendicular and parallel to the partition to spray and disinfect the medical supplies above the horizontal partition.

[0013] Second, water is conveyed into the water tank through the connecting pipe and sprayed out as cleaning water 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 dirt attached to the outer surface of the medical supplies will be cleaned off in cooperation with the cleaning water, which can effectively ensure that when steam is sprayed for disinfection on the surface subsequently, the areas where the dirt adheres to the medical supplies can be thoroughly disinfected.

[0014] Third, the connecting rod driven to move up and down drives the lifting plate to move up and down on the inner wall of the pressure discharge barrel. When the lifting plate rises, the air in the disinfection 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 sprayed out from the second one-way valve. During the reciprocating up and down movement of the lifting plate, the air in the disinfection box is pumped outwards, so as to make the inside of the disinfection box in a negative pressure state. This can reduce the interference of air on the penetration of steam. By establishing a negative pressure environment, steam can quickly and thoroughly enter all the voids of the medical supplies, especially some tiny holes or dead corners.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

A cleaning area and a disinfection area are provided in the disinfection box 1; A driving and carrying component 3, which includes a first carrying circular frame 305 arranged in the disinfection box 1. The inner wall of the first carrying circular frame 305 is hermetically and rotatably installed with a second carrying circular frame 309. A plurality of partition plates 315 are evenly installed inside the second carrying circular frame 309. Each partition plate 315 divides the inside of the second carrying circular frame 309 into a plurality of disinfection areas.

A single medical supply is carried in the disinfection area. The partition plates 315 prevent the medical supplies from colliding with each other. The electromagnet 325 drives the magnetic lifting plate 318 at the bottom end inside the second carrying circular frame 309 to slide upward, so that the rotating spray heads 319 rotate downward to spray air on the medical supplies for disinfection. During each process of driving the first carrying circular frame 305 and the second carrying circular frame 309 to rotate, each set of rotating spray heads 319 can rotate an angle to spray air on the medical supplies placed inside the second carrying circular frame 309, so as to ensure that the steam sprayed by the rotating spray heads 319 can effectively disinfect the medical supplies; A pressure relief component 5, which is used to discharge the air inside the disinfection box 1 to reduce the air pressure; A jet disinfection component 6, which is used to input steam into the disinfection area and inside the second carrying circular frame 309 for disinfection.

[0021] Refer to Figures 2 to 5, on both sides of the disinfection box 1, two pairs of sealing plates 301 are symmetrically installed. Each pair of sealing plates 301 is internally equipped with a linear driving device 302. The linear driving device 302 is electrically connected to a controller 7. The driving end of the linear driving device 302 is fixedly installed with a connecting piece 303. One end of the connecting piece 303 penetrates through the disinfection box 1 and is rotatably installed with a toothed ring 304. The inner wall of the toothed 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. 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 with a first electromagnet 321. Two second electromagnets 322 are equidistantly installed on one side of the second bearing circular frame 309. The first electromagnet 321, the second electromagnets 322 and the controller 7 are electrically connected. One side of the second bearing circular frame 309 is hermetically and slidably installed with a circular cover 310. A hollow main shaft 308 is rotatably installed in the second bearing circular frame 309. The hollow main shaft 308 penetrates through the first bearing circular frame 305 and extends to one side thereof. The outer wall of the hollow main shaft 308 is communicated with a partition plate 315. A chute is opened in the partition plate 315. The inner wall of the chute is slidably connected to a magnetic lifting plate 318. The upper end of each rotating spray head 319 is communicated with a connecting hose 320. A first spring 317 is fixedly installed between the magnetic lifting plate 318 and the chute. An output pipe 316 is fixedly installed on the inner wall of the chute. The magnetic lifting plate 318 is slidably connected to the outer wall of the output pipe 316. The connecting hose 320 penetrates through the partition plate 315 and is communicated with the output pipe 316. The output pipe 316 penetrates through the partition plate 315 and is communicated with the hollow main shaft 308. A rotating connecting sleeve 312 is sleeved on the outer wall of the hollow main shaft 308 on one side of the first bearing circular frame 305. Two hollow pipes 313 are symmetrically installed on the outer wall of the rotating connecting sleeve 312. The hollow pipes 313 penetrate through the rotating connecting sleeve 312 and are communicated with the hollow main shaft 308. One end of the hollow pipe 313 is fixedly installed with a joint 314. During the process of driving the first bearing circular frame 305 and the second bearing circular frame 309 to rotate, the circular cover 310 can seal the second bearing circular frame 309 to avoid steam leakage. At the same time, after the medical supplies are cleaned, during the first steam disinfection, the steam in the disinfection box 1 can reach a relatively high temperature and humidity level. When steam is sprayed into the second bearing circular frame 309 for the second time, the medical supplies will be heated intensively and directionally, which helps to improve the disinfection effect on the surface and inside of the items.

[0022] Refer to Figure 4, on one side of the connecting member 303, a U-shaped frame 306 is fixedly installed. On one side of the U-shaped frame 306, a rotary driving member 307 is fixedly installed. The rotary driving member 307 can be an existing stepper motor. A stepper motor is a motor that performs precise position control through electrical pulse control. Different from traditional DC motors or AC motors, the rotation of a stepper motor is achieved through "stepping" movements at fixed angles. The output end of the rotary driving member 307 penetrates 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. 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, thereby driving the medical supplies to rotate intermittently.

[0023] Refer to Figures 1 to 2 , it further includes a spray cleaning assembly 4. The spray cleaning assembly 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 externally connected to an external water source. A plurality of nozzles 402 are evenly installed on the lower end surface of the water tank 401. A plurality of drain ports 404 are fixedly installed at a lower position on one side of the disinfection box 1.

[0024] Refer to Figures 6 to 7 , an installation block 501 is fixedly installed at the inner top end of the disinfection box 1. A transmission rod 502 is rotatably installed in the installation block 501. A tooth head 513 is fixedly installed at one end of the transmission rod 502. The tooth head 513 meshes with the tooth ring 304. A reciprocating lead screw 504 is rotatably installed on the upper end surface of the disinfection box 1. The lower end of the reciprocating lead screw 504 penetrates through the disinfection box 1 and is fixedly installed with a rotating short shaft 503. The rotating short shaft 503 is rotationally connected to the disinfection box 1. The rotating short shaft 503 and the transmission rod 502 are driven by a bevel gear pair. A rotating sleeve 505 that matches the reciprocating lead screw 504 is sleeved on the outer wall of the reciprocating lead screw 504. Two connecting rods 506 are symmetrically installed on the outer wall of the rotating sleeve 505. A pressure discharge barrel 507 is fixedly installed on the upper end surface of the disinfection box 1 and near the controller 7. A bottom plate 508 is fixedly installed at the inner bottom end of the pressure discharge barrel 507. A first one-way valve 509 is embedded in the bottom plate 508. A lifting plate 511 is hermetically slidably installed in the pressure discharge 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. The connecting rod 506 is fixedly connected to the lifting plate 511. By discharging the air in the disinfection box 1 and reducing the air pressure in the disinfection box 1, air has a significant impact on the steam sterilization process. Air not only affects the heating efficiency of steam but also may hinder the penetration of steam, resulting in incomplete sterilization effects.

[0025] Refer to Figures 8 to 9, on the side of the disinfection box 1 away from the sealing door 2, a support plate 601 is fixedly installed. On the upper end surface of the support plate 601, a steam generator 602 is fixedly installed. On the inner wall of the disinfection box 1 and at a position away from the sealing door 2, two steam spray nozzles 605 are symmetrically installed. A second solenoid valve 606 is connected to the opposite sides of the two steam spray nozzles 605. 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. On the inner wall of the disinfection box 1 and at the position of the steam spray nozzles 605, two connecting plates 603 are symmetrically installed. A first solenoid valve 604 is connected to the upper ends of the two connecting plates 603. The first solenoid valve 604 and the steam generator 602 are connected through a pipeline. A clamping groove 607 is formed in the connecting plate 603. A trigger sensor 608 is fixedly installed in the clamping groove 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 the electromagnetic principle to control the flow of fluids. It uses the action of an electromagnetic coil and controls the opening and closing of the valve by the on and off of the current, thereby realizing the control of fluids in the pipeline system. The trigger sensor 608 is a prior art. The trigger sensor 608 is a sensor that emits a signal when a specific condition or event occurs. It triggers a corresponding response or control operation by sensing changes in the external environment or objects.

[0026] The working principle of the present invention is as follows: First, clean medical supplies: By opening the sealing door 2 and then opening the round cover 310, place the medical items to be cleaned and disinfected into the second bearing round frame 309. The provided partition 315 divides the second bearing round frame 309 into four independent spaces to separately load medical supplies (for attachment Figure 4Taking the four partition plates 315 as an example, close the sealing door 2, install the round cover 310 back to its original position, turn on the rotary drive 307 through the controller 7, and drive the hollow main shaft 308 to rotate. The rotating hollow main shaft 308 will drive the second bearing circular frame 309 to rotate. The controller 7 will control the input voltage of the first electromagnet 321 to enhance the magnetic force and adsorb with the second electromagnet 322. Therefore, during the rotation of the second bearing circular frame 309, it will drive the first bearing circular frame 305 to rotate together. The rotating second bearing circular frame 309 and the first bearing circular frame 305 will drive the medical supplies to rotate together. The provided partition plates 315 can effectively prevent the medical supplies from colliding with each other. Connect the external water source through the connecting pipe 403 to transport water into the water tank 401 and spray the cleaning water from the nozzle 402. The cleaning water will enter the second bearing circular frame 309 through the first connecting hole 323 and the second connecting hole 324 and contact the medical supplies for cleaning. As the medical supplies are continuously driven to rotate, combined with the cleaning water, the dirt attached to the outer surface of the medical supplies can be cleaned off. This can effectively avoid that when the steam is ejected for disinfection later, the places where the dirt is attached to the medical supplies are not thoroughly disinfected; Second, reduce the air pressure in the disinfection chamber 1: During the process of driving the first bearing circular frame 305 to rotate, the first bearing circular frame 305 will drive the toothed ring 304 to engage 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 lead screw 504 to rotate through the bevel gear pair. The rotating reciprocating lead screw 504 drives the rotating sleeve 505 and the connecting rod 506 to move up and down. The moving connecting rod 506 drives the lifting plate 511 to move up and down 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 chamber 1 will enter between the lifting plate 511 and the bottom plate 508 through the first one-way valve 509. 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. During the process of continuously driving the lifting plate 511 to reciprocate up and down, the air in the disinfection chamber 1 will also be continuously pumped out, thereby reducing the air in the disinfection chamber 1 and lowering the air pressure, so as to make the inside of the disinfection chamber 1 in a negative pressure state. This can reduce the interference of air on the penetration of steam. By establishing a negative pressure environment, the steam can quickly and thoroughly enter all the gaps of the medical supplies, especially some tiny holes or dead corners; Third, disinfect the medical supplies: the controller 7 controls the linear drive device 302 to drive the connecting member 303 to move the first bearing circular frame 305 and the second bearing circular frame 309, and moves the first bearing circular frame 305 and the second bearing circular frame 309 from the cleaning area to the disinfection area. The steam generator 602 is turned on by the controller 7, and the steam generated by the steam generator 602 is transported to the steam nozzle 605 through a pipeline and sprayed to perform the first disinfection of the first bearing circular frame 305, the second bearing 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 bearing circular frame 305 and the second bearing 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 electromagnetic 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 by rotating the 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 bearing 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 bearing circular frame 309, the second bearing 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 field of the first electromagnet 321 and adsorb it with another first electromagnet 321 (refer to the attached Figure 2 ), so that the second connecting hole 324 and the first connecting hole 323 will be completely staggered, so that the second bearing circular frame 309 remains sealed, and the two first electromagnets 321 after adsorption will re-synchronize and rotate in the first bearing circular frame 305 and the second bearing circular frame 309. During the periodic rotation of the first bearing circular frame 305 and the second bearing circular frame 309, the voltage controlled by the controller 7 to the first electromagnet 321 will be kept constant; It should also be noted that when the rotating nozzle 319 starts to spray steam for disinfection, the positions of the first bearing circular frame 305 and the second bearing circular frame 309 will be driven by the linear driving device 302 above the electromagnet block 325. At this time, the rotation driving member 307 will drive the first bearing circular frame 305 and the second bearing circular frame 309 to rotate intermittently. Each rotation will make the arranged partition plate 315 in the second bearing circular frame 309 in a cross state. The jet angles of the arranged magnetic lifting plates 318 are as follows: The state of the rotating nozzle 319 at the lower part is that the repulsive force generated by the electromagnet block 325 will push the magnetic lifting plate 318 at the lower part in the second bearing circular frame 309 to rise. After rising, the rotating nozzles 319 rotatably installed on both sides of the magnetic lifting plate 318 will rotate downward by gravity to jet air on the medical supplies at the lowest part in the second bearing circular frame 309 (the medical supplies will naturally rotate to the lowest part in the second bearing circular frame 309 due to their own weight); The state of the rotating nozzle 319 in the horizontal position in the second bearing circular frame 309 is that the medical supplies will be above the partition plate 315 in the horizontal state due to their own gravity. The rotating nozzle 319 above the partition plate 315 in the horizontal state will be flush with the partition plate 315 in the horizontal state to jet air on the medical supplies above the partition plate 315 in the horizontal state. The rotating nozzle 319 below the partition plate 315 in the horizontal state will rotate naturally due to its own gravity and maintain a 90° rotation angle with the partition plate 315 in the horizontal state to jet air for disinfection of the medical supplies; The state of the rotating nozzle 319 above the second bearing circular frame 309 is that the rotating nozzle 319 is perpendicular and parallel to the partition plate 315 to jet air for disinfection of the medical supplies above the partition plate 315 in the horizontal state; As described above in the appendix Figure 10 shown; According to the above, jet air for disinfection of the medical supplies in each area in the second bearing circular frame 309. During the periodic intermittent rotation of the second bearing circular frame 309 and the continuous jet air disinfection of the rotating nozzle 319, the medical supplies can continuously rotate in the second bearing circular frame 309 to disinfect the whole medical supplies, avoiding areas where disinfection is not in place and incomplete disinfection. The set pressure valve 311 can discharge pressure outward after the air pressure in the second bearing circular frame 309 increases to a certain extent to avoid excessive air pressure in the second bearing circular frame 309.
