Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a sterilization cabinet for intensive care units. Background Technology

[0002] Medical disinfection cabinets are high-performance disinfection devices designed specifically for medical facilities such as hospitals, clinics, and laboratories. They are mainly used to efficiently and reliably sterilize or disinfect medical devices, instruments, dressings, etc., in order to prevent cross-infection and ensure medical safety.

[0003] Existing disinfection cabinets use fixed-position ultraviolet (UV) lamps for irradiation. This results in better sterilization on the side closer to the lamp due to higher irradiation intensity, while the side farther from the lamp experiences significantly reduced sterilization due to severe UV attenuation. Although some devices use up-and-down movement of the UV lamp to expand the irradiation range, the slow scanning speed and long reciprocating intervals prevent continuous and uniform coverage, leaving sterilization blind spots or weak areas. This makes it difficult to meet the thorough sterilization requirements of medical devices with high cleanliness standards. Furthermore, existing equipment lacks an effective temperature control mechanism during sterilization. Prolonged operation of the UV lamp causes the internal temperature to rise continuously, potentially damaging heat-sensitive medical devices and causing the air inside the chamber to expand and escape. Without effective filtration, this could introduce potential pathogens into the external environment. When cooling is needed, there is a lack of a two-way airflow control structure that can both introduce clean, cool air and prevent the backflow of contaminated external air, making it difficult to balance temperature control and airtight protection. Summary of the Invention

[0004] This application proposes a disinfection cabinet for intensive care units, which has the advantages of sterilization and uniform coverage, in order to solve the problem of uneven sterilization intensity of existing equipment.

[0008] Preferably, the filtration mechanism includes a filter housing, which is fixedly installed at the bottom of the inner cavity of the housing. A valve sleeve is fixedly sleeved on the upper left side of the filter housing. Through holes are opened on both the front and rear sides of the upper surface of the valve sleeve. A one-way valve is fixedly sleeved in the middle of the two through holes. Multiple filter blocks are fixedly sleeved at equal intervals in the middle of the inner cavity of the filter housing. An air outlet is opened on the right side of the bottom of the inner cavity of the filter housing.

[0009] Preferably, the loading mechanism includes multiple loading seats, which are equidistantly fixedly sleeved in the middle of the inner cavity of the housing. Multiple loading disks are equidistantly movably sleeved in the middle of the loading seats. A first friction wheel is fixedly sleeved on the bottom of the curved surface of the loading disk, and two adjacent first friction wheels are in frictional contact. A mounting shaft is movably sleeved on the right side of the multiple loading seats. Multiple second friction wheels are fixedly mounted on the curved surface of the mounting shaft at equal intervals. The second friction wheels are in frictional contact with adjacent first friction wheels. A fifth conical wheel is fixedly mounted on the bottom end of the mounting shaft.

[0010] Preferably, the driving mechanism includes a driving component, and a first conical wheel is fixedly installed at both ends of the output shaft of the driving component. The first conical wheel is in frictional contact with the adjacent second conical wheel. A third conical wheel is fixedly sleeved on the right side of the output shaft of the driving component, and a fourth conical wheel is movably sleeved on the right side of the filter shell. The third conical wheel is in frictional contact with the fourth conical wheel, and the fifth conical wheel is in frictional contact with the fourth conical wheel.

[0011] Preferably, the rear side of the door body is provided with a reflective coating, the push plate in front of the inner cavity of the second mounting shell on the left side gradually increases in length from top to bottom, the push plate on the rear side of the inner cavity of the second mounting shell on the left side gradually decreases in length from top to bottom, the push plate in front of the inner cavity of the second mounting shell on the right side gradually decreases in length from top to bottom, and the push plate on the rear side of the inner cavity of the second mounting shell on the right side gradually increases in length from top to bottom.

[0012] Preferably, the contact surfaces of the friction block and the inner sleeve are both provided with a rough coating, the friction block is made of a material that can be attracted by a magnet, and the sealing plate is made of a high-density material.

[0013] Preferably, the one-way valve on the front side opens downwards, and the one-way valve on the rear side opens upwards. The carrier, the carrier plate, and the first friction wheel are all made of transparent material.

[0014] Preferably, the contact surfaces between the first and second cone wheels, the third and fourth cone wheels, and the fifth and fourth cone wheels are all provided with a rough coating.

[0015] The beneficial effects of this invention are as follows: 1. When the drive unit is started in the forward direction, the left electromagnetic ring is energized and the right electromagnetic ring is de-energized. At this time, the transmission mechanism on the right side is disengaged, and the transmission mechanism on the left side is activated. The drive mechanism drives the rotating sleeve of the polarizing mechanism to move downward. Simultaneously, because the length of the push plate at the front of the inner cavity of the left second mounting shell gradually increases from top to bottom, and the length of the push plate at the rear of the inner cavity of the left second mounting shell gradually decreases from top to bottom, when the left rotating sleeve alternately contacts its adjacent push plate from top to bottom, the upward rotation angle of the left rotating sleeve gradually increases, and the downward rotation angle gradually decreases. Conversely, the same applies when the drive unit is started in the reverse direction. The left electromagnetic ring is de-energized and the right electromagnetic ring is energized. At this time, because the length of the push plate at the rear of the inner cavity of the left second mounting shell gradually increases from top to bottom, the transmission mechanism on the right side is activated. The length of the push plate at the front of the inner cavity gradually decreases from top to bottom, while the length of the push plate at the rear of the inner cavity of the second mounting shell on the right side gradually increases from top to bottom. This means that when the rotating sleeve on the right side moves upward, the upward rotation angle of the rotating sleeve on the right side gradually decreases, and the downward rotation angle gradually increases. This ensures that the ultraviolet light generated by the left or right rotating sleeve, through the adjacent transmission mechanism, moves the ultraviolet lamp up and down, and always reciprocates within a fixed angle on its front side. This solves the problem of the ultraviolet lamp with a fixed position having a strong sterilization effect on the side closer to the ultraviolet lamp and a weak sterilization effect on the side farther away from the ultraviolet lamp; it also solves the problem of the long up-and-down scanning time interval of the up-and-down moving ultraviolet lamp, which results in a weak sterilization effect.

[0016] 2. When the drive mechanism is activated, the drive mechanism drives the loading tray in the middle of the loading mechanism to rotate the medical device placed in its inner cavity. This causes the side of the medical device away from the ultraviolet lamp to alternately turn towards the ultraviolet lamp, overcoming the problem of weak sterilization effect on the side of the medical device away from the ultraviolet lamp. In addition, when the air temperature in the inner cavity of the shell irradiated by the ultraviolet lamp rises, the air in the inner cavity collides, pushing the front one-way valve to open. The high-temperature air flows out of the device through the air outlet after being filtered by the front one-way valve and multiple filter blocks. When the inner cavity of the shell needs to be cooled, the fan is activated. The fan drives the airflow from bottom to top, pushing the sealing plate to move upward, so that the air in the inner cavity of the shell flows out of the inner cavity of the shell through the gap between the sealing plate and the side groove. The cold air outside flows into the inner cavity of the shell after being filtered by the filter blocks and then flows into the inner cavity of the shell through the rear one-way valve. This achieves temperature control of the inner cavity of the shell, preventing the release of germs in the inner cavity of the shell into the air, while also preventing germs in the outside air from flowing into the inner cavity of the shell, and avoiding high temperature damage to heat-sensitive medical devices.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1 to 6 As shown, a disinfection cabinet for an intensive care unit includes a housing 1, a door 2 on the front side of the housing 1, and a left end of the door 2 movably fitted onto the left side of the housing 1. The rear side of the door 2 has a reflective coating to reflect the ultraviolet light emitted by the ultraviolet lamp 308, thereby increasing the ultraviolet coverage intensity and improving the sterilization efficiency. The cabinet also includes: The polarizing mechanism 3 is located at the front of the inner cavity of the housing 1. The polarizing mechanism 3 includes two first mounting shells 301. The two first mounting shells 301 are symmetrically fixedly installed on the left and right sides of the front of the inner cavity of the housing 1. A threaded rod 302 is movably sleeved in the middle of the first mounting shell 301. A second conical wheel 303 is fixedly installed at the bottom end of the threaded rod 302. A slider 304 is slidably sleeved in the middle of the first mounting shell 301. The slider 304 is threadedly connected to the threaded rod 302. A sliding shaft 305 is fixedly installed on the adjacent side of the two sliders 304. A rotating sleeve 306 is movably sleeved on the curved surface of the sliding shaft 305. A transmission mechanism 307 is provided on the adjacent side of the two rotating sleeves 306. A UV lamp 308 is provided on the adjacent side of the two transmission mechanisms 307. A second mounting shell 309 is fixedly installed on the adjacent side of the two first mounting shells 301. Multiple push plates 310 are fixedly installed at equal intervals on the front and rear sides of the inner cavity of the second mounting shell 309. In this design, the length of the push plate 310 at the front of the inner cavity of the left second mounting shell 309 gradually increases from top to bottom, while the length of the push plate 310 at the rear of the inner cavity of the left second mounting shell 309 gradually decreases from top to bottom. This results in the left rotating sleeve 306 rotating upward at an angle that gradually increases and downward at an angle that gradually decreases when it alternately contacts its adjacent push plate 310 from top to bottom. Similarly, the length of the push plate 310 at the front of the inner cavity of the right second mounting shell 309 gradually decreases from top to bottom, while the length of the push plate 310 at the rear of the inner cavity of the right second mounting shell 309 gradually increases from top to bottom. This results in the right rotating sleeve 306 rotating upward at an angle that gradually decreases and downward at an angle that gradually increases when it alternately contacts its adjacent push plate 310 from top to bottom. Wind power mechanism 4 is located at the top of housing 1. Filter mechanism 5 is located at the bottom of the inner cavity of housing 1. Carrying mechanism 6 is located in the middle of the inner cavity of housing 1. Drive mechanism 7 is located between carrying mechanism 6 and polarizing mechanism 3.

[0022] Please see Figure 2 , Figure 5 and Figure 6 As shown, the transmission mechanism 307 includes an outer sleeve 3071, which is fixedly installed on the side of the rotating sleeve 306 near the ultraviolet lamp 308. An electromagnetic ring 3072 is fixedly installed in the middle of the inner cavity of the outer sleeve 3071. Multiple guide grooves are equidistantly opened on the curved circumference of the inner cavity of the outer sleeve 3071. A friction block 3073 is slidably sleeved in the middle of the guide groove. An inner sleeve 3074 is slidably sleeved on the inner curved surface of the multiple friction blocks 3073. One end of the ultraviolet lamp 308 is fixedly connected to the inner sleeve 3074. The contact surfaces of the friction block 3073 and the inner sleeve 3074 are both provided with a rough coating. The friction block 3073 is made of a material that can be attracted by a magnet. The friction block 3073 is made of carbon steel. This allows the electromagnetic ring 3072 to attract the friction block 3073 and the inner sleeve 3074 to fit tightly when the electromagnetic ring 3072 is energized. This enables the outer sleeve 3071 to rotate and the inner sleeve 3074 to rotate through the friction block 3073 when the rotating sleeve 306 drives the outer sleeve 3071 to rotate.

[0023] Please see Figures 2 to 3 As shown, the wind power mechanism 4 includes a top seat 401, which is fixedly installed on the top of the housing 1. Fans 402 are symmetrically fixedly installed on the left and right sides of the inner cavity of the top seat 401. A sealing plate 403 is slidably sleeved in the middle of the inner cavity of the top seat 401. Side grooves 404 are opened on the upper part of the front and rear sides of the inner cavity of the top seat 401. The sealing plate 403 is made of high-density material and high-carbon steel, thereby improving the quality of the sealing plate 403. When the fan 402 is de-energized, even if the air in the inner cavity of the housing 1 expands under the heating of the ultraviolet lamp 308, it cannot push the sealing plate 403 to move upward. At this time, when the fan 402 rotates, the fan 402 drives the airflow to flow from bottom to top, pushing the sealing plate 403 to move upward, so that the air in the inner cavity of the housing 1 flows out of the inner cavity of the housing 1 through the gap between the sealing plate 403 and the side groove 404.

[0024] Please see Figures 2 to 5 As shown, the filter mechanism 5 includes a filter housing 501, which is fixedly installed at the bottom of the inner cavity of the housing 1. A valve sleeve 502 is fixedly sleeved on the upper left side of the filter housing 501. Through holes are opened on both the front and rear sides of the upper surface of the valve sleeve 502. A one-way valve 503 is fixedly sleeved in the middle of the two through holes. Multiple filter blocks 504 are fixedly sleeved at equal intervals in the middle of the inner cavity of the filter housing 501. An air outlet 505 is opened on the right side of the bottom of the inner cavity of the filter housing 501. The front one-way valve 503 opens downwards, and the rear one-way valve 503 opens upwards. This allows the air inside the housing 1 to expand under the heating of the ultraviolet lamp 308, and then flow out of the housing 1 through the front one-way valve 503. After the air inside the housing 1 is drawn away by the fan 402, the outside air flows into the housing 1 through the rear one-way valve 503, thus enabling the exchange of air between the housing 1 and the outside air.

[0025] Please see Figure 2 and Figure 4 As shown, the loading mechanism 6 includes multiple loading seats 601, which are equidistantly fixedly sleeved in the middle of the inner cavity of the housing 1. Multiple loading disks 602 are equidistantly movably sleeved in the middle of the loading seats 601. A first friction wheel 603 is fixedly sleeved on the bottom of the curved surface of the loading disk 602. Adjacent first friction wheels 603 are in frictional contact. A mounting shaft 604 is movably sleeved on the right side of the multiple loading seats 601. Multiple second friction wheels 605 are equidistantly fixedly mounted on the curved surface of the mounting shaft 604. The second friction wheels 605 are in frictional contact with adjacent first friction wheels 603. A fifth conical wheel 606 is fixedly mounted on the bottom end of the mounting shaft 604. The carrier 601, carrier tray 602, and first friction wheel 603 are all made of transparent material, and the carrier 601, carrier tray 602, and first friction wheel 603 are all made of colorless glass, so that the ultraviolet light generated by the ultraviolet lamp 308 can penetrate the carrier 601, carrier tray 602, and first friction wheel 603 to irradiate the medical device placed in the inner cavity of the carrier tray 602, thereby sterilizing the medical device.

[0026] Please see Figure 2 and Figure 4 As shown, the drive mechanism 7 includes a drive component 701. First conical wheels 702 are fixedly installed at both ends of the output shaft of the drive component 701. The first conical wheels 702 are in frictional contact with the adjacent second conical wheels 303. A third conical wheel 703 is fixedly sleeved on the right side of the output shaft of the drive component 701. A fourth conical wheel 704 is movably sleeved on the right side of the filter housing 501. The third conical wheel 703 is in frictional contact with the fourth conical wheel 704. A fifth conical wheel 606 is in frictional contact with the fourth conical wheel 704. The contact surfaces of the first cone wheel 702 and the second cone wheel 303, the third cone wheel 703 and the fourth cone wheel 704, and the fifth cone wheel 606 and the fourth cone wheel 704 are all provided with a rough coating, thereby reducing the probability of slippage and improving transmission efficiency.

[0027] Working principle: When the driving unit 701 is activated in the forward direction, the left electromagnetic ring 3072 is energized and the right electromagnetic ring 3072 is de-energized. The output end of the driving unit 701 drives the first conical wheel 702 to rotate forward, the first conical wheel 702 drives the second conical wheel 303 to rotate forward, the second conical wheel 303 drives the threaded rod 302 to rotate forward, the threaded rod 302 drives the slider 304 to move downward, the slider 304 drives the sliding shaft 305 to move downward, the sliding shaft 305 drives the rotating sleeve 306, which is movably sleeved with it, to move downward, and the push plate 310, which is in contact with the rotating sleeve 306, pushes the rotating sleeve 306 to rotate. At this time, because the left electromagnetic ring 3072 is energized and the right electromagnetic ring 3072 is de-energized, the driving unit 701 drives the first conical wheel 702 to rotate forward. Electricity causes the transmission mechanism 307 on the right to disconnect, while the transmission mechanism 307 on the left continues to operate. Simultaneously, as the length of the push plate 310 at the front of the inner cavity of the second mounting shell 309 on the left gradually increases from top to bottom, and the length of the push plate 310 at the rear of the inner cavity of the second mounting shell 309 on the left gradually decreases from top to bottom, when the rotating sleeve 306 on the left alternately contacts its adjacent push plate 310 from top to bottom, the upward rotation angle of the rotating sleeve 306 on the left gradually increases, and the downward rotation angle gradually decreases. At the same time, the rotating sleeve 306 on the left drives the ultraviolet lamp 308 to rotate in the same direction and angle as the rotating sleeve 306 on the left through the transmission mechanism 307 on the left. Conversely, when the reverse start drive 701 is activated, the left electromagnetic ring 3072 is de-energized, and the right electromagnetic ring 3072 is energized. At this time, because the length of the push plate 310 at the front of the inner cavity of the right second mounting shell 309 gradually decreases from top to bottom, and the length of the push plate 310 at the rear of the inner cavity of the right second mounting shell 309 gradually increases from top to bottom, when the right rotating sleeve 306 moves upward, the upward rotation angle of the right rotating sleeve 306 gradually decreases, and the downward rotation angle gradually increases. At this time, the right rotating sleeve 3072... 6. The transmission mechanism 307 on the right side drives the ultraviolet lamp 308 to rotate in the same direction and angle as the rotating sleeve 306 on the right side. This ensures that the ultraviolet light generated by the ultraviolet lamp 308 always reciprocates within a fixed angle in front of it during the up-and-down movement of the ultraviolet lamp 308. This overcomes the problems of existing ultraviolet lamps 308 with fixed positions and up-and-down movement, where the sterilization effect is strong on the side closer to the ultraviolet lamp 308 and weak on the side farther from the ultraviolet lamp 308, and the long up-and-down scanning time interval of the up-and-down moving ultraviolet lamp 308, resulting in a weak sterilization effect. Furthermore, when the driving component 701 rotates, the output shaft of the driving component 701 drives the third conical wheel 703 to rotate, the third conical wheel 703 drives the fourth conical wheel 704 to rotate, the fourth conical wheel 704 drives the fifth conical wheel 606 to rotate, the fifth conical wheel 606 drives the mounting shaft 604 to rotate, the mounting shaft 604 drives the second friction wheel 605 to rotate, the fifth conical wheel 606 drives the first friction wheel 603 to rotate, the first friction wheel 603 drives the carrier plate 602 to rotate, and the carrier plate 602 drives the medical device placed in its inner cavity to rotate, thereby causing the side of the medical device away from the ultraviolet lamp 308 to alternately turn towards the ultraviolet lamp 308, overcoming the problem that the sterilization effect is weak on the side of the medical device away from the ultraviolet lamp 308; Furthermore, when the air temperature inside the housing 1 irradiated by the ultraviolet lamp 308 rises, the air inside the housing 1 collides, pushing the front one-way valve 503 to open. The high-temperature air flows out of the device through the air outlet 505 after being filtered by the front one-way valve 503 and multiple filter blocks 504. When the housing 1 needs to be cooled, the fan 402 is started. The fan 402 drives the airflow from bottom to top, pushing the sealing plate 403 to move upward, so that the air inside the housing 1 flows out of the housing 1 through the gap between the sealing plate 403 and the side groove 404. The cold air outside flows into the housing 1 through the filter block 504 and then through the rear one-way valve 503. This achieves the control of the temperature inside the housing 1, preventing the release of germs from the housing 1 into the air, and at the same time preventing germs from the outside air from flowing into the housing 1.
