Description

Technical Field

[0001] The present invention relates to the technical field of cleaning and disinfection devices, and particularly to a device for cleaning and disinfecting nursing instruments used in a supply room. Background Art

[0002] The supply room, also known as the disinfection supply center, is a department in the hospital that undertakes the cleaning, disinfection, sterilization of all reusable diagnostic instruments, appliances and items in each department, as well as the supply of sterile items. Among them, the most frequently used are nursing instruments. Therefore, the number of times of cleaning and disinfecting nursing instruments is the largest. Nursing instruments usually include scalpels, forceps, and scissors. During use, they will directly contact the patient's body, body fluids, blood, etc. If not cleaned and disinfected, various pathogens such as bacteria, viruses, fungi, etc. may remain on them. These pathogens may spread between different patients, causing cross-infection. Strict cleaning and disinfection of nursing instruments is one of the key measures to control hospital infections.

[0003] Currently, when disinfecting nursing instruments, they are usually placed in a basket together for disinfection, causing the instruments to gather together and block each other, resulting in some areas not being able to fully expose to ultraviolet light, thereby reducing the disinfection effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for cleaning and disinfecting nursing instruments used in a supply room, so as to solve the problem that when disinfecting nursing instruments currently, they are usually placed in a basket together for disinfection, causing the instruments to gather together and block each other, resulting in some areas not being able to fully expose to ultraviolet light, thereby reducing the disinfection effect.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A device for cleaning and disinfecting nursing instruments used in a supply room, including a housing. The housing has a cylindrical cavity with an opening facing forward. A plurality of ultraviolet lamps arranged in a circular array are installed on the wall surface of the cylindrical cavity.

A plurality of partition grooves arranged in a circular array are formed on the inner surface of the inner circle of the rotating frame. The inner wall of each partition groove is movably connected with an adjustable plate that can move up and down.

[0007] Preferably, support blocks are connected to both ends of each adjustable plate, and adjustment sliding grooves for the support blocks to move up and down are formed on the wall surface of each partition groove.

[0008] Preferably, sliding grooves for the front and back sliding of the support blocks are cooperatively formed on both sides of each of the adjusting plates. A baffle is movably connected to the rear end of each of the adjusting plates. A T-shaped slider is fixedly connected to the rear end of each of the adjusting plates. A T-shaped sliding groove for the up and down movement of the T-shaped slider is cooperatively formed at the front end of each of the baffles.

[0009] Preferably, the bottom of each of the partition grooves is an inclined slope. A plurality of water passing openings are formed at the rear end of the rotating frame. Each of the water passing openings communicates with one of the partition grooves, and the water passing openings are located at the lower end of the bottom of the partition grooves in terms of terrain. A drain port adapted to cooperate with the water passing openings is formed at the rear end of the housing. The adjusting plate is of a grid structure.

[0010] Preferably, a water collecting box is inlaid and installed in the drain port. The water collecting box is used to catch the liquid flowing out of the water passing openings. A sealing plate is fixedly installed at the rear of the water collecting box. The sealing plate is used to seal the drain port, and the sealing plate is detachably connected to the housing.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 13 , the present invention provides a technical solution.

[0034] A cleaning and disinfection device for nursing instruments in a supply room includes an outer shell 1. The outer shell 1 has a cylindrical cavity with an opening facing forward. A plurality of ultraviolet lamps 3 arranged in an annular array are installed on the wall surface of the cylindrical cavity. A protective cover 4 is sleeved on the surface of each ultraviolet lamp 3. A placing cylinder 18 is coaxially and fixedly connected inside the cylindrical cavity. A vertically downward placing opening 19 is opened at the bottom of the placing cylinder 18. A rotating rack 5 is coaxially sleeved on the surface of the placing cylinder 18. The rotating rack 5 is rotatably connected to the placing cylinder 18. A plurality of partition grooves 6 arranged in an annular array are cooperatively opened on the inner surface of the inner circle of the rotating rack 5. An adjustable plate 7 that can move up and down is movably connected to the inner wall of each partition groove 6. The placing opening 19 allows nursing instruments to fall out of the placing cylinder 18. The partition groove 6 and the placing opening 19 are used in cooperation. When the rotating rack 5 rotates, when the partition groove 6 is aligned with the placing opening 19, the nursing instruments falling from the placing opening 19 will fall into the partition groove 6, so that a plurality of gathered nursing instruments can be automatically separated, and each instrument can be relatively evenly exposed to the disinfection environment, improving the comprehensiveness of disinfection;

[0035] For example, when using ultraviolet disinfection, a shadow area is likely to be formed in the middle area of the instruments gathered in the placing cylinder 18, so that the irradiation effect of ultraviolet rays on the instruments in the middle area is reduced. After the instruments fall into each partition groove 6 in turn and are separated, the number of instruments in each partition groove 6 is small, greatly reducing the formed shadow area and improving the disinfection effect.

[0036] Secondly, by installing an adjustable plate 7 that can move up and down in each partition slot 6, it is beneficial to prevent the stacking of instruments that fall into the partition slot 6, further reducing the shadow area. The specific reason is that by moving the adjustable plate 7 up and down, the space for placing instruments in the partition slot 6 can be controlled. Suppose three instruments fall into the partition slot 6. The first and second instruments lie flat separately on the adjustable plate 7. After the third instrument falls, it stacks on the second instrument. At this time, by moving the adjustable plate 7 upward, the three instruments are driven to move upward. At this time, the stacked third instrument first moves back into the instrument placing cylinder 18, and then stops the upward movement of the adjustable plate 7 and rotates the rotating frame 5. At this time, the stacked third instrument will get stuck in the instrument placing cylinder 18, and the first and second instruments will follow the rotation. And due to the blockage of the outer ring of the instrument placing cylinder 18 and the limitation of the space by the adjustable plate 7, the first and second instruments will not stack during the rotation of the rotating frame 5, and each instrument can be evenly exposed to the disinfection environment, ensuring the comprehensiveness of disinfection. According to needs, a visual detector can be used to cooperate with the adjustment of the up and down movement of the adjustable plate 7.

[0037] Conventionally, the rotating frame 5 is made of a transparent material to allow ultraviolet rays to pass through smoothly.

[0038] Both ends of each adjustable plate 7 are connected with support blocks 10. The wall surface of each partition slot 6 is correspondingly provided with an adjustment chute 11 for the support blocks 10 to move up and down. By controlling the up and down movement of the support blocks 10, the adjustable plate 7 moves up and down. The specific control method is that a threaded rod 12 is rotatably connected in each adjustment chute 11, each threaded rod 12 threadedly penetrates through a support block 10, and a first motor 13 is installed in each adjustment chute 11. The output end of each first motor 13 is coaxially and fixedly connected to one end of a threaded rod 12. By starting the first motor 13 to drive the threaded rod 12 to rotate, due to the thread action and the limiting action of the adjustment chute 11, the rotation of the threaded rod 12 causes the support block 10 to move up and down along the track of the adjustment chute 11.

[0039] Furthermore, push-pull chutes 9 for the support blocks 10 to slide back and forth are correspondingly provided on both sides of each adjustable plate 7. By providing the push-pull chutes 9, the adjustable plate 7 can be pulled outwards, facilitating the staff to pull out the adjustable plate 7 to take out the instruments. The rear end of each adjustable plate 7 is movably connected with a baffle 8. The rear end of each adjustable plate 7 is fixedly connected with a T-shaped slider. The front end of each baffle 8 is correspondingly provided with a T-shaped chute for the T-shaped slider to move up and down. By providing the T-shaped slider and the T-shaped chute, the baffle 8 does not affect the up and down movement of the adjustable plate 7, and when the adjustable plate 7 is pulled outwards, the baffle 8 will be driven to move together. By providing the baffle 8, when the adjustable plate 7 is pulled out, the baffle 8 blocks the instruments, so that the instruments are located on the adjustable plate 7 and move outwards together with the adjustable plate 7.

[0040] The bottom of each partition slot 6 is an inclined plane. A plurality of water inlets 14 are provided at the rear end of the rotating rack 5. Each water inlet 14 communicates with a partition slot 6, and the water inlet 14 is located at the lower end of the bottom of the partition slot 6, so that the liquid in the partition slot 6 flows towards the direction of the water inlet 14. A drain port 15 is provided at the rear end of the outer shell 1 for cooperating with the water inlet 14. The function of the drain port 15 is to drain the liquid flowing out from the water inlet 14 outside the outer shell 1. During the rotation of the rotating rack 5, a plurality of water inlets 14 will be sequentially connected to the drain port 15. When connected, the liquid will flow along the direction of the partition slot 6 to the water inlet 14 to the drain port 15 and finally be discharged outside the outer shell 1. The adjusting plate 7 is of a grid structure to allow the liquid to pass through.

[0041] Furthermore, a water collecting box 16 is inlaid and installed in the drain port 15. The water collecting box 16 is used to catch the liquid flowing out from the water inlet 14. A sealing plate 17 is fixedly installed behind the water collecting box 16. The sealing plate 17 is used to seal the drain port 15, and the sealing plate 17 is detachably connected to the outer shell 1.

[0042] A gear ring 27 is coaxially and fixedly connected to the rear end of the rotating rack 5. A gear block 28 is rotatably connected in the outer shell 1. The gear ring 27 is meshed with the gear block 28. A third motor 29 is fixedly installed at the rear end of the outer shell 1. The output end of the third motor 29 is coaxially and fixedly connected to the gear block 28. By starting the third motor 29 to drive the third motor 29 to rotate, the gear block 28 rotates to drive the gear ring 27 to rotate, thereby causing the rotating rack 5 to rotate.

[0043] A cleaning groove 30 for cleaning and nursing instruments is provided on the surface of the outer shell 1. Conventionally, a faucet is installed on the cleaning groove 30, a pipeline for draining water is installed in the cleaning groove 30, and a transport frame 20 is placed in the cleaning groove 30. Conventionally, the transport frame 20 is of a hollow mesh frame structure. The instruments are collected by placing them into the transport frame 20 and then placed on the cleaning groove 30 for manual rinsing repeatedly. After rinsing, the transport frame 20 is placed into the instrument placing cylinder 18, and the instruments are poured into the instrument placing cylinder 18 to prepare for disinfection.

[0044] A cross-shaped insert block 25 is rotatably connected to the inner wall of the rear end of the instrument placing cylinder 18 coaxially. A cross-shaped insertion hole 24 for the cross-shaped insert block 25 to be inserted into is coaxially provided at the rear end of the transport frame 20. A second motor 26 is fixedly connected to the rear end of the outer shell 1. The output end of the second motor 26 is coaxially and fixedly connected to the cross-shaped insert block 25. When the transport frame 20 is placed into the instrument placing cylinder 18, the cross-shaped insert block 25 is inserted into the cross-shaped insertion hole 24 to complete the connection. By starting the second motor 26 to drive the cross-shaped insert block 25 to rotate, the transport frame 20 can be rotated to pour the instruments in the transport frame 20 into the instrument placing cylinder 18, and according to needs, the transport frame 20 can be rotated to block the instrument placing port 19 so that the instruments will not fall into the instrument placing port 19 again.

[0045] Furthermore, a positioning block 21 is fixedly connected to the left side of the carrier frame 20. A positioning chute 22 for the positioning block 21 to be embedded is cooperatively provided on the inner wall of the placement cylinder 18, and an arc chute 23 for the positioning block 21 to rotate is cooperatively provided on the inner wall of the placement cylinder 18, facilitating the positioning of the carrier frame 20.

[0046] A door panel 2 for closing the cylindrical cavity is detachably connected to the surface of the outer shell 1.

[0047] The specific solution of this scheme is as follows: Collect all the nursing instruments to be cleaned and disinfected into the carrier frame 20, then place them into the cleaning tank 30, turn on the faucet for cleaning. After cleaning, remove the door panel 2, open the cylindrical cavity, align the positioning block 21 on the carrier frame 20 with the positioning chute 22, embed the positioning block 21 into the positioning chute 22, place the carrier frame 20 into the placement cylinder 18, and make the cross-shaped insertion block 25 embed into the cross-shaped insertion hole 24. Then install the door panel 2 to close the cylindrical cavity. Then, start the second motor 26 to rotate the carrier frame 20, so that the positioning block 21 moves along the track of the arc chute 23. During rotation, the instruments will fall from the carrier frame 20 into the placement cylinder 18 and then slide into the placement port 19.

[0048] Start the third motor 29 to drive the gear block 28 to rotate. The rotation of the gear block 28 drives the gear ring 27 to rotate, and the rotation of the gear ring 27 drives the rotating frame 5 to rotate. During the rotation of the rotating frame 5, when the partition slot 6 is aligned with the placement port 19, the instruments will fall from the placement port 19 onto the adjusting plate 7 in the partition slot 6. Start the first motor 13 to drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 drives the support block 10 to move upward along the track of the adjusting chute 11. The up and down movement of the support block 10 drives the adjusting plate 7 to move upward, causing the T-shaped slider to move upward along the track of the T-shaped chute until the adjusting plate 7 moves to a suitable position. Then, during the rotation of the rotating frame 5, the instruments fall into multiple partition slots 6 in sequence and are then disinfected by the ultraviolet lamp 3.

[0049] When the disinfection is completed, open the cylindrical cavity, and the adjusting plate 7 can be pulled outwards, so that the support block 10 moves along the track of the push-pull chute 9. The movement of the adjusting plate 7 drives the baffle 8 and the instruments thereon to move. When the instruments are moved out of the outer shell 1, the instruments can be conveniently taken out.

[0050] When the liquid enters the partition slot 6, it will flow along the bottom groove towards the water passing port 14 and then flow into the water collection box 16 through the water passing port 14 for collection. By removing the water collection box 16, the collected liquid can be conveniently processed.

[0051] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
