Description

Technical Field

[0001] The present invention belongs to the technical field of disinfection equipment, and specifically relates to a portable automatic disinfection device and method for operating rooms. Background Art

[0002] Ultraviolet disinfection uses ultraviolet light with an appropriate wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing the death of growth cells and / or the death of regenerative cells, achieving the effect of sterilization and disinfection. Because ultraviolet disinfection has advantages such as high efficiency and environmental protection, it is commonly used for disinfection in operating rooms.

[0003] The commonly used ultraviolet disinfection equipment in operating rooms is the ultraviolet disinfection lamp. Through the irradiation of a large area of ultraviolet light, a large-scale disinfection operation of the operating room is realized. However, due to the mechanism of ultraviolet disinfection, the positions that cannot be irradiated by ultraviolet light will not produce a disinfection effect. Therefore, ultraviolet disinfection has certain limitations. In order to enhance the disinfection effect of the ultraviolet lamp, in related technologies, the position of the ultraviolet lamp is mostly automatically adjusted to reduce the dead angle of ultraviolet irradiation, so as to achieve the purpose of enhancing the disinfection effect. Among them, the automatic position adjustment is mostly divided into simple lifting adjustment or installing guiding components such as slide rails on the ceiling, and then realizing the automatic adjustment of the position of the ultraviolet equipment. However, in actual applications, the above methods all have certain defects. For example, simple lifting adjustment has little effect on eliminating the dead angle of ultraviolet irradiation caused by item occlusion, while fixed slide rails cannot be widely promoted and applied due to problems such as cumbersome installation, complexity, rigid movement paths, and high installation costs.

[0004] For example, a related patent discloses an energy-saving sterilization and disinfection device for operating rooms, with the application number CN2018104626120. This solution is driven by a control switch, and the electric push rod extends downward for vertical adjustment; the ultraviolet lamp can slide in the annular chute of the adjustment ring plate and can perform horizontal circular motion, and the four ultraviolet lamps of the adjustment ring plate can be adjusted locally. However, when applied to an operating room with a large number of items, since the movement degree of the ultraviolet lamp in the operating room is low, it is still unable to effectively disinfect the entire environment of the operating room.

[0005] In view of this, the present invention proposes a portable automatic disinfection device and method for operating rooms to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] like Figures 1 to 7 As shown, a portable automatic disinfection device for an operating room described in the present invention comprises a portable mounting table 1 and an ultraviolet disinfection lamp 11 mounted on the mounting table 1. At the same time, a power supply, cables and other structures matching the ultraviolet disinfection lamp 11 are also installed on the mounting table 1 to supply power to the ultraviolet disinfection lamp 11 so that the ultraviolet disinfection lamp 11 can work normally. In other embodiments of the present invention, other forms of disinfection equipment can also be installed on the mounting table 1, such as air circulation disinfection equipment, disinfectant spraying equipment, etc., to diversify the disinfection methods.

[0049] Also included are a range switching mechanism and an automatic guidance mechanism;

[0050] The range switching mechanism is installed on the mounting platform 1, and the range switching mechanism is used to adjust the action range of the ultraviolet disinfection lamp 11;

[0051] The range switching mechanism includes a walking wheel 2, a lifting rod 21 and a transmission member;

[0052] The walking wheel 2 is rotatably mounted at the bottom of the mounting platform 1. The existence of the walking wheel 2 makes it easier for the disinfection device to move on the ground, so that the staff can push the disinfection device to switch the disinfection position.

[0053] The lifting rod 21 is installed on the top of the mounting platform 1, and the ultraviolet disinfection lamp 11 is fixedly installed on the lifting rod 21;

[0054] The transmission member is installed between the walking wheel 2 and the lifting rod 21, and the transmission member is used to control the lifting rod 21 to perform lifting movement when the walking wheel 2 rotates;

[0055] The automatic guiding mechanism cooperates with the range switching mechanism to guide the moving path of the mounting table 1.

[0056] The transmission member includes a transmission lead screw 22, a positioning tube 23, a moving block 24, and a hinged rod 25;

[0057] The transmission lead screw 22 is rotatably installed at the top of the mounting table 1, and the transmission lead screw 22 is connected to the traveling wheel 2 by belt drive;

[0058] The positioning tube 23 is fixedly installed at the top of the mounting table 1, and the lifting rod 21 extends into the inner cavity of the positioning tube 23;

[0059] Two symmetrically arranged reciprocating threads are provided on the transmission lead screw 22. The moving block 24 is installed on the transmission lead screw 22, and the moving block 24 is in screw drive connection with the transmission lead screw 22 through the reciprocating threads. When the transmission lead screw 22 rotates, the moving block 24 performs a linear reciprocating motion along the axial direction of the transmission lead screw 22 under the principle of screw drive;

[0060] The hinged rod 25 is installed between the moving block 24 and the lifting rod 21. Both ends of the hinged rod 25 are hinged to the moving block 24 and the lifting rod 21 respectively. The hinged rod 25 and the moving block 24 form a triangular structure. When the two moving blocks 24 approach each other, the hinged rod 25 gradually tends to be in a vertical state.

[0061] During actual disinfection operations, as the mounting table 1 moves on the ground, the traveling wheel 2 rotates. Since the traveling wheel 2 is connected to the transmission lead screw 22 by belt drive, the movement of the mounting table 1 relative to the ground will cause the transmission lead screw 22 to rotate, and then the two moving blocks 24 perform linear motions. When the two moving blocks 24 approach each other, under the action of the hinged rod 25, the lifting rod 21 installed in the positioning tube 23 moves upward. On the contrary, when the two moving blocks 24 move away from each other, the lifting rod 21 descends. Therefore, the ultraviolet disinfection lamp 11 installed at the end of the lifting rod 21 performs periodic lifting motions, thereby changing the action range of the ultraviolet disinfection lamp 11 and reducing the probability of the existence of ultraviolet disinfection dead angles.

[0062] In the present invention, by linking the lifting motion of the ultraviolet disinfection lamp 11 with the motion of the disinfection device and cooperating with the automatic guiding mechanism, when the disinfection device moves automatically on the ground, the ultraviolet disinfection lamp 11 can perform regular lifting motions synchronously, thereby realizing the common changes in the horizontal position and the vertical position, effectively expanding the ultraviolet disinfection range, and reducing the probability of the existence of disinfection dead angles.

[0063] As a preferred embodiment of the present invention, the automatic guiding mechanism includes a guiding belt 3 and a positioning suction cup 31;

[0064] The guiding belt 3 is a strip-shaped structure made of elastic rubber material. The positioning suction cups 31 are installed on the guiding belt 3 at equal intervals. The guiding belt 3 is fixedly installed on the ground through the positioning suction cups 31 by adsorption fixation. This can not only fix the guiding belt 3 on the ground to provide direction guidance for the movement of the disinfection device, but also enable the automatic guiding mechanism to be recovered and re-laid after use. Compared with the fixed guiding mechanism, the present invention can adjust the laying position of the automatic guiding mechanism by itself, making the paths diversified.

[0065] The guiding belt 3 is formed by hinging multiple rubber belts. The positioning suction cups 31 and the rubber belts are arranged alternately. The multiple rubber belts are hinged to form the guiding belt 3. When laying the guiding belt 3, the hinged connection method can be used to enhance the flexibility of the angle adjustment between multiple rubber belts, and ultimately make the extension path of the guiding belt 3 diversified.

[0066] The automatic guiding mechanism further includes a winding roller 32 and a winding motor 33;

[0067] A storage chamber 34 is opened in the mounting table 1. The winding roller 32 is rotatably installed in the storage chamber 34. The end of the guiding belt 3 is fixedly installed on the winding roller 32. A winding motor 33 is fixedly installed in the storage chamber 34. The output end of the winding motor 33 is fixedly connected to the winding roller 32. An L-shaped magnetic attraction plate 35 is fixedly installed at the tail end of the guiding belt 3. The existence of the magnetic attraction plate 35 is used to intercept the end of the guiding belt 3 when recovering the guiding belt 3, so as to facilitate the unfolding of the guiding belt 3 when using it again.

[0068] To avoid the harm caused by ultraviolet disinfection to the human body, in the ultraviolet disinfection space, it is not suitable for personnel to stay for a long time. Therefore, it is necessary to make the disinfection device move automatically. The existence of the automatic guiding mechanism can fix the movement path of the disinfection device, and then, while ensuring the disinfection effect, effectively reduce the probability of collision and tipping during the movement of the device. Specifically, in the present invention, the automatic guiding mechanism is composed of a guiding belt 3 and positioning suction cups 31. When laying the guiding belt 3, the staff manually pulls the magnetic attraction plate 35 and presses the first positioning suction cup 31 on the ground. Subsequently, the installation table 1 is pushed, causing the installation table 1 to move in the operating room. As the distance between the installation belt and the magnetic attraction plate 35 increases, the guiding belt 3 is pulled, unfolded, and laid on the ground. During this process, the positioning suction cups 31 on the guiding belt 3 are pressed one by one, causing the positioning suction cups 31 to be fixed on the ground, and thus the movement trajectory of the installation table 1 can be approximately formed on the ground. Until the guiding belt 3 is laid, the staff starts the winding motor 33 and the ultraviolet disinfection lamp 11, and at the same time, the personnel quickly leave the operating room. At this time, driven by the winding motor, the winding roller 32 gradually rotates, and then the guiding belt 3 is recovered and wound. As the winding continues, the installation table 1 gradually moves along the laid guiding belt 3. During this process, the ultraviolet disinfection lamp 11 continuously rises and falls for disinfection until the installation table 1 moves to the magnetic attraction plate 35, completing a single movement of the disinfection device. In practical applications, by flexibly adjusting the rotation speed of the winding motor 33 and the laying path of the guiding belt 3, the disinfection operation of the disinfection device in the operating room can be made more flexible and effective.

[0069] In the present invention, by setting up an automatic guiding component, before ultraviolet disinfection, the automatic guiding component is laid on the ground. During the ultraviolet disinfection process, the movement of the disinfection device is realized by the winding of the guiding belt 3. Cooperating with the range switching mechanism, the disinfection range of the ultraviolet disinfection lamp 11 is effectively expanded. At the same time, the laying and recovery of the automatic guiding component are both relatively convenient. And due to the flexibility of the automatic guiding component during laying, the movement route of the disinfection device can be conveniently adjusted by the staff in different environments, making the disinfection operation more flexible and further enhancing the convenience of the disinfection operation.

[0070] As a preferred embodiment of the present invention, an extension groove 4 is formed at the bottom of the mounting table 1, and the extension groove 4 is connected to the storage chamber 34 in a conducting manner. The guiding belt 3 extends into the extension groove 4. The setting of the extension groove 4 fixes the path of the guiding belt 3 extending outside the mounting table 1, thereby making the process of unwinding or winding the guiding belt 3 smoother. A support plate 41 is installed in the extension groove 4, and symmetrically arranged pressure rollers 42 are rotatably installed at both ends of the support plate 41. A pressure belt 43 is sleeved on the two pressure rollers 42. The pressure belt 43 cooperates with the pressure rollers 42 to press the guiding belt 3. The cooperation of the pressure rollers 42 and the pressure belt 43 can make the guiding belt 3 be pressed onto the ground during the unwinding process by using the change of the gap between the extension groove 4 and the ground, so that the positioning suction cups 31 on the guiding belt 3 are more closely combined with the ground. Since the ground in the operating room is relatively smooth, the fixing effect of the positioning suction cups 31 is better. And due to the influence of friction, the pressure belt 43 can move synchronously with the guiding belt 3. Therefore, during the pressing process of the guiding belt 3, there will be no large frictional loss with the extension groove 4, and the service life of the guiding belt 3 is prolonged.

[0071] A connecting pipe 5 is fixedly installed on the pressure belt 43, and a top rod 51 is fixedly installed in the connecting pipe 5. The distance between adjacent two connecting pipes 5 is the same as the distance between adjacent two positioning suction cups 31. Since in the initial state, the magnetic attraction plate 35 is attached to the mounting table 1, and at this time the connecting pipe 5 is aligned with the first positioning suction cup 31 on the guiding belt 3. Therefore, when the guiding belt 3 is unwound, under the frictional force between the guiding belt 3 and the pressure belt 43, the pressure belt 43 rotates around the pressure roller 42, so that the connecting pipe 5 is aligned with the positioning suction cup 31 one by one. A docking pipe 52 is fixedly installed on the positioning suction cup 31. The inner cavity of the docking pipe 52 is stepped, and a closing piece 53 is elastically installed in the inner cavity of the docking pipe 52 through a spring. During the alignment process of the connecting pipe 5 and the positioning suction cup 31, the top rod 51 fixedly installed in the connecting pipe 5 is inserted into the inside of the docking pipe 52, the connecting pipe 5 covers the outside of the docking pipe 52, and at the same time the top rod 51 pushes the closing piece 53, causing the docking pipe 52 to open.

[0072] A telescopic cylinder 6 is fixedly installed between the two moving blocks 24. A negative pressure chamber 61 and a pressure boosting chamber 62 are formed on the support plate 41. The telescopic cylinder 6 is connected to the negative pressure chamber 61 and the pressure boosting chamber 62 through an air suction pipe 63 and an air outlet pipe 64 respectively. In the present invention, both the air suction pipe 63 and the air outlet pipe 64 are one-way conduction pipes. During the process of the guiding belt 3 being unfolded and laid, after the positioning suction cup 31 on the guiding belt 3 is aligned with the connecting pipe 5, it first enters the range of the pressure boosting chamber 62 and then enters the range of the negative pressure chamber 61. When entering the pressure boosting chamber 62, the two moving blocks 24 approach each other, and the telescopic cylinder 6 gradually contracts, discharging air into the pressure boosting chamber 62 through the air outlet pipe 64. Since the connecting pipe 5 is in communication with the docking pipe 52 at this time and the connecting pipe 5 penetrates through the pressing belt 43, the air in the pressure boosting chamber 62 flows into the positioning suction cup 31 along the connecting pipe 5 and the docking pipe 52 and is sprayed on the ground to impact the dust and impurities on the ground. Then, as the mounting table 1 continues to move, the connecting pipe 5 and the docking pipe 52 enter the range of the negative pressure chamber 61. At this time, the two moving blocks 24 separate from each other, and the telescopic cylinder 6 extends, causing a negative pressure to act on the air suction pipe 63, the negative pressure chamber 61, the connecting pipe 5, the docking pipe 52, and the positioning suction cup 31, thereby extracting the air between the positioning suction cup 31 and the ground, enhancing the negative pressure adsorption of the positioning suction cup 31 on the ground. When the guiding belt 3 is wound up, as the mounting table 1 moves, the positioning suction cup 31 on the guiding belt 3 is first aligned with the negative pressure chamber 61 and then with the pressure boosting chamber 62. Therefore, the positioning suction cup 31 is first evacuated by negative pressure and then inflated by pressure boosting, enabling the positioning suction cup 31 to actively disengage from the ground, facilitating the disassembly and recycling of the guiding belt 3.

[0073] As a preferred embodiment of the present invention, a lifting groove 65 is formed on the mounting table 1. A lifting block 66 is elastically installed in the lifting groove 65 through a spring. The support plate 41 and the guiding belt 3 are both installed on the lifting block 66. An adjusting bolt 67 is threadedly installed on the mounting table 1. The adjusting bolt 67 extends into the lifting groove 65, and the adjusting bolt 67 is used to adjust the height of the lifting block 66.

[0074] To further improve the flexibility of the device during use, a lifting groove 65 is also formed on the mounting table 1, and a lifting block 66 is elastically installed in the lifting groove 65. When the device is moving and not ready to lay the guiding belt 3, the adjusting bolt 67 is at the uppermost end. At this time, under the action of the spring, the lifting block 66 is at the topmost position, and the pressure roller 42 and the pressing belt 43 do not press the guiding belt 3. Due to the adsorption between the magnetic attraction plate 35 and the mounting table 1, the positioning suction cup 31 is separated from the ground. When it is ready to lay the guiding belt 3, the adjusting bolt 67 is manually turned, causing the adjusting bolt 67, the lifting block 66, the pressure roller 42, and the pressing belt 43 to descend, thereby making the positioning suction cup 31 fit the ground. When the mounting table 1 moves, the guiding belt 3 is automatically unfolded, further enhancing the flexibility of the device during use.

[0075] As Figure 8 shown, a portable automatic disinfection method for an operating room, the method comprising the following steps:

[0076] S1: The staff manually push the disinfection device to the designated position in the operating room, and then manually turn the adjusting bolt 67, causing the lifting block 66 to descend, causing the pressure roller 42 to press against the guiding belt 3;

[0077] S2: Manually push the disinfection device to move, and the moving direction is opposite to the winding direction of the guiding belt 3. As the movement progresses, the guiding belt 3 gradually unfolds and is adsorbed on the ground through the positioning suction cups 31;

[0078] S3: Push the disinfection device to move along a preset route, so that the extension path of the guiding belt 3 is determined, and then turn on the disinfection device, and the ultraviolet disinfection lamp 11 and the winding motor 33 are started synchronously;

[0079] S4: The winding motor 33 continuously rotates, causing the winding roller 32 to pull the guiding belt 3, so that the disinfection device moves along the arrangement path of the guiding belt 3. During this process, the ultraviolet disinfection lamp 11 dynamically disinfects the operating room.
