Abstract
Description
Technical Field
[0001] This invention relates to the field of medical equipment technology, and in particular to a disinfection device for intensive care nursing. Background Technology
[0002] ICU, or Intensive Care Unit, is the core facility for treating critically ill patients. Treatment, nursing care, and rehabilitation can be carried out simultaneously. It provides isolated spaces and equipment for critically ill or comatose patients, offering optimal care, comprehensive treatment, integrated medical and nursing services, as well as early postoperative rehabilitation, joint care, and exercise therapy. As a key area for hospital infection control, the cleanliness and disinfection effectiveness of the ICU environment directly affect patient treatment outcomes and health. Furthermore, its complex internal medical environment places extremely high demands on disinfection techniques.
[0003] Existing disinfection methods for intensive care units mainly include spray disinfection and ultraviolet lamp disinfection. Traditional ultraviolet lamps emit light in a diffuse manner, resulting in low energy utilization and insufficient irradiation intensity in the target area, making it difficult to meet the needs of local high-intensity disinfection and affecting the disinfection effect and efficiency. In addition, when the light emitted by ultraviolet lamps directly irradiates the human body at a certain distance, it can cause harm to the human body and affect health.
[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention
[0005] Therefore, it is necessary to provide a disinfection device for intensive care nursing that addresses the problems existing in current disinfection devices.
[0006] The above objectives are achieved through the following technical solutions:
[0007] A disinfection device for intensive care nursing includes a support frame and disinfection components. A plurality of disinfection components are arranged circumferentially at intervals on the support frame. Each disinfection component includes a disinfection lamp and a reflective component disposed on one side of the disinfection lamp. The reflective component is used to reflect and guide the light generated by the disinfection lamp. When the distance between a human body and the disinfection component is less than a preset value, the disinfection component can rotate relative to the support frame so that the light generated by the disinfection lamp is away from the human body.
[0008] Furthermore, a light-absorbing component is provided on one side of the disinfection lamp. When the distance between the human body and the disinfection component is less than the preset value, the light-absorbing component absorbs the light generated by the disinfection lamp.
[0009] Furthermore, the reflective component includes multiple reflective plates, and the light-absorbing component includes multiple light-absorbing plates. The reflective plates and the light-absorbing plates are alternately arranged and connected in sequence. When the distance between the human body and the disinfection component is greater than the preset value, the reflective plate separates the light-absorbing plate from the disinfection lamp. When the distance between the human body and the disinfection component is less than the preset value, the light-absorbing plate is exposed to the light generated by the disinfection lamp to absorb the light generated by the disinfection lamp.
[0010] Furthermore, when the distance between the human body and the disinfection component is greater than the preset value, the multiple reflectors form an arc-shaped structure.
[0011] Furthermore, the light-absorbing plate is disposed on the side of the reflector away from the disinfection lamp.
[0012] Furthermore, the light-absorbing plate is made of an elastic material.
[0013] Furthermore, the light-absorbing plate is a bent plate.
[0014] Furthermore, heat dissipation fins are provided at the bends of the light-absorbing plate.
[0015] Furthermore, the bracket is equipped with a ventilation assembly.
[0016] The beneficial effects of this invention are as follows: Compared with the divergent light of traditional disinfection lamps, this invention reflects and guides the light generated by the disinfection lamp through a reflective component, which can improve energy utilization and increase the irradiation intensity of the target area, thereby adapting to the needs of local high-intensity disinfection and improving the disinfection effect and efficiency; when a human body approaches, the disinfection component can rotate so that the light generated by the disinfection lamp is away from the human body, avoiding harm and affecting health when it directly irradiates the human body at a certain distance.

[0034] like Figures 1 to 11 As shown, this embodiment of the invention provides a disinfection device for intensive care nursing, including a support 100 and disinfection components 200. Multiple disinfection components 200 are arranged circumferentially at intervals on the support 100. Each disinfection component 200 includes a disinfection lamp 201 and a reflective component disposed on one side of the disinfection lamp 201. The reflective component is used to reflect and guide the light generated by the disinfection lamp 201. When the distance between the human body and the disinfection component 200 is less than a preset value, the disinfection component 200 can rotate relative to the support 100 so that the light generated by the disinfection lamp 201 is away from the human body.
[0035] Compared to the divergent light of traditional disinfection lamps 201, the reflective component reflects and guides the light generated by the disinfection lamp 201, which can improve energy utilization and increase the irradiation intensity of the target area, thereby adapting to the needs of local high-intensity disinfection and improving the disinfection effect and efficiency. When a human body approaches, the disinfection component 200 can rotate so that the light generated by the disinfection lamp 201 is away from the human body, avoiding harm and affecting health when it directly irradiates the human body at a certain distance.
[0036] Currently, non-contact disinfection methods generally include ultraviolet (UV) light, blue light, pulsed light, and infrared light, but UV disinfection is the most commonly used due to its broad-spectrum bactericidal effect, targeting bacteria, viruses, and fungi, and its high efficiency and speed. Among UV rays, UVC has the highest energy and is the main wavelength band of disinfection lamps, especially at 254 nm, which can damage microbial DNA / RNA, preventing its replication. It also poses the greatest risk to humans, causing skin burns and corneal inflammation. Therefore, effective protection is necessary when using UV light for disinfection to avoid direct exposure to the human body. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) stipulates that the occupational exposure limit for UVC is 6 μW / cm², 8 hours / day. For example, if a UV lamp has an intensity of 600 μW / cm² at 1 meter, a distance of approximately 10 meters is required to meet the standard. To reduce damage when the human body is close, the preset value range is [5, +∞), with 10 meters being the preferred value. Of course, other forms of non-contact disinfection can also be used to further reduce damage when the human body is close, such as infrared or blue light.
[0037] The bracket 100 has casters at its bottom with brakes, and a handle on one side for moving the disinfection device to a suitable position for disinfection. The bracket 100 also has a power supply and controller corresponding to the disinfection lamp 201. The disinfection lamp 201 is preferably rod-shaped, and the corresponding reflective component is also elongated and positioned along the length of the lamp. However, the disinfection lamp 201 can also be spherical or other shapes.
[0038] The number of disinfection components 200 can be selected, with a minimum of 3 and preferably 4. Sensors corresponding sequentially to the disinfection components 200 are arranged on the circumference of the bracket 100. These sensors can be one of the following: infrared sensor, ultrasonic sensor, capacitive proximity sensor, millimeter-wave radar, or lidar. The bracket 100 also has a processor connected to multiple sensors. When one sensor detects a human body approaching, the processor controls all disinfection components 200 to rotate, causing the light emitted by the disinfection lamps 201 to move away from the human body. Conversely, when multiple sensors, such as two sensors, detect a human body approaching (i.e., two people are near), the processor can directly control all disinfection lamps 201 to turn off.
[0039] In addition, the disinfection device can be set to dual disinfection modes: outward irradiation and directional irradiation. A remote control device can be installed to switch between the two modes, improving its applicability. Of course, the disinfection device can also switch autonomously based on its own sensors and processor modules, switching to directional irradiation at appropriate times to reduce harm to the human body.
[0040] The bracket 100 includes a top plate 101 and a bottom plate 102, which are connected by a connecting column. The disinfection component 200 is disposed between the top plate 101 and the bottom plate 102. Specifically, both the top plate 101 and the bottom plate 102 are provided with lamp holders 103, and the disinfection lamp 201 is disposed between the two lamp holders 103. Both the top plate 101 and the bottom plate 102 are provided with rotating rings 105 around the lamp holders 103. The two rotating rings 105 are provided with rotating plates 106 at their close ends. The reflector is disposed between the two rotating plates 106. The bottom plate 102 is provided with a first motor 107 and is equipped with a corresponding power supply and control module. The control module is connected to the processor, thereby controlling the output end of the first motor 107 to drive the rotating rings 105 to rotate, so as to drive the rotating plates 106, the disinfection lamp 201 and the reflector to rotate. In the initial state, that is, when no one is near the disinfection process, the reflective component is located inside the disinfection lamp 201 relative to the bracket 100, so that the light generated by the disinfection lamp 201 is directed towards the four sides of the bracket 100, that is, in the mode of irradiating disinfection in all directions.
[0041] Preferably, a light-absorbing component is also provided on one side of the disinfection lamp 201. When the distance between the human body and the disinfection component 200 is less than a preset value, the light-absorbing component absorbs the light generated by the disinfection lamp 201.
[0042] It is worth noting that when the distance between the human body and the disinfection component 200 is less than a preset value, the light-absorbing component corresponding to the disinfection component 200 closest to the human body absorbs the light generated by the disinfection lamp 201. Of course, it is also possible for all the light-absorbing components 200 to absorb the light generated by their respective disinfection lamps 201; the specific settings can be selected.
[0043] Of course, when the distance between the human body and the disinfection component 200 is less than the preset value, the disinfection lamp 201 can be automatically turned off to avoid harming the human body from the source.
[0044] Preferably, the reflective component includes multiple reflective plates 202, and the light-absorbing component includes multiple light-absorbing plates 203. The reflective plates 202 and the light-absorbing plates 203 are alternately arranged and connected in sequence. When the distance between the human body and the disinfection component 200 is greater than a preset value, the reflective plate 202 separates the light-absorbing plate 203 from the disinfection lamp 201. When the distance between the human body and the disinfection component 200 is less than the preset value, the light-absorbing plate 203 is exposed to the light generated by the disinfection lamp 201 in order to absorb the light generated by the disinfection lamp 201.
[0045] When a person is not near, the light-absorbing plate 203 and the disinfection lamp 201 are blocked by the reflector 202. At this time, the reflector 202 reflects and guides the light generated by the disinfection lamp 201, while the light-absorbing plate 203 does not come into contact with the light generated by the disinfection lamp 201. When a person approaches, the light generated by the disinfection lamp 201 moves away from the human body, and the adjacent reflectors 202 move away from each other, so that the light-absorbing plate 203 is exposed to the light generated by the disinfection lamp 201 to absorb the light and further reduce the harm to the human body.
[0046] The light-absorbing plate 203 can be made of a material capable of absorbing ultraviolet light, such as an organic ultraviolet absorber whose molecular structure contains a conjugated system and absorbs ultraviolet light through electronic transitions, specifically benzotriazoles or benzophenones; or an inorganic ultraviolet absorber that physically reflects or absorbs ultraviolet light and has high stability, specifically nano-titanium dioxide or zinc oxide. Preferably, the light-absorbing plate 203 only absorbs ultraviolet light without reflecting it, thereby reducing the amount of ultraviolet light diffusion.
[0047] Of course, the reflective component can be a single reflective element, and the light-absorbing component can be a single light-absorbing element. Before a human body approaches, the light-absorbing component is located on the side of the reflective component away from the disinfection lamp 201. After the human body approaches, the light-absorbing component moves to the side of the reflective component closer to the disinfection lamp 201, that is, the light-absorbing component is exposed to the light generated by the disinfection lamp 201. The structure that drives the movement of the light-absorbing component can be a telescopic mechanism such as a cylinder or hydraulic rod.
[0048] Preferably, when the distance between the human body and the disinfection component 200 is greater than a preset value, the multiple reflectors 202 form an arc-shaped structure to converge the light, thereby further increasing the irradiation intensity of the target area. Simultaneously, when the light emitted by the disinfection lamp 201 is directed away from the human body, it further reduces the harm of the light to the human body.
[0049] The concave surface of the arc-shaped structure formed by the reflector 202 faces the side of the disinfection lamp 201 to converge the light.
[0050] Preferably, see Figures 4 to 7 The light-absorbing plate 203 is located on the side of the reflector 202 away from the disinfection lamp 201.
[0051] Each rotating plate 106 is equipped with a second motor 204, and a take-up roller 205 is also rotatably mounted on the rotating plate 106. The take-up roller 205 is driven to rotate by the output end of the second motor 204. Guide posts 206 are provided on the reflector plates 202 on both sides of the reflector assembly. The guide posts 206 are arranged vertically along the length of the reflector plate 202. The rotating plate 106 has elongated holes 207 for the ends of the guide posts 206 to slide. The guide posts 206 and the take-up roller 205 are fixed to the two ends of the pull rope 208, respectively. A guide wheel 209 is rotatably mounted on the rotating plate 106, and the pull rope 208 overlaps the outside of the guide wheel 209. The output end of the second motor 204 drives the take-up roller 205 to rotate, and the pull rope 208 pulls the guide post 206 to slide along the corresponding elongated hole 207, causing adjacent reflector plates 202 to move away from each other, thus exposing the light-absorbing plate 203 to the light generated by the disinfection lamp 201 for light absorption.
[0052] As a structural variation of the present invention, see [link to relevant documentation]. Figure 8 The light-absorbing plate 203 is slidably inserted into two adjacent reflector plates 202.
[0053] The reflector 202 has sliding holes 210 on both sides, and the end of the light-absorbing plate 203 is slidably inserted into the sliding hole 210. When adjacent reflectors 202 are close to each other, the light-absorbing plate 203 can be completely located within the two reflectors 202. At this time, the reflectors 202 reflect and guide the light generated by the disinfection lamp 201, while the light-absorbing plate 203 does not come into contact with the light generated by the disinfection lamp 201. When adjacent reflectors 202 are far apart, the light-absorbing plate 203 is exposed to the light generated by the disinfection lamp 201 to absorb the light. In addition, a limiting member is provided at the sliding connection between the sliding hole 210 and the light-absorbing plate 203 to prevent the light-absorbing plate 203 from completely sliding out of the sliding hole 210.
[0054] Preferably, the light-absorbing plate 203 is made of an elastic material.
[0055] After the nearby human body moves away, the output end of the second motor 204 rotates in the opposite direction, and the light-absorbing plate 203 is elastic to pull the two adjacent reflectors 202, so that the two adjacent reflectors 202 move closer to each other to reset.
[0056] Preferably, the light-absorbing plate 203 is a bent plate to form a larger light-absorbing area, while also facilitating the deformation of the light-absorbing plate 203.
[0057] Preferably, see Figure 8 The light-absorbing plate 203 is provided with heat dissipation fins 108 at the bend to absorb and diffuse the heat generated by the disinfection lamp 201.
[0058] The heat dissipation fins 108 can penetrate the light-absorbing plate 203 to improve heat transfer efficiency. The bent light-absorbing plate 203 also has a certain heat dissipation function. The heat dissipation fins 108 can be made of aluminum alloy, copper, or graphene composite materials.
[0059] Preferably, the bracket 100 is provided with a ventilation component 109 to allow air circulation and improve the disinfection effect and efficiency.
[0060] The ventilation component 109 can be a ventilation fan and can be installed on the top plate 101. The bracket 100 is also equipped with a power supply and controller corresponding to the ventilation component 109 to facilitate start-up and shutdown control.
[0061] When in use, this invention uses multiple disinfection lamps 201 in conjunction with a ventilation component 109 for disinfection. Compared to the divergent light of traditional disinfection lamps 201, the light generated by the disinfection lamps 201 is reflected, guided, and focused by the reflective component with an arc structure, which can improve energy utilization and increase the irradiation intensity of the target area, thereby adapting to the needs of local high-intensity disinfection and improving the disinfection effect and efficiency.
[0062] When a sensor corresponding to a disinfection component 200 detects a human body approaching, for example, if the sensor detects that the distance to the human body is less than a preset value, the processor controls all disinfection components 200 to rotate. Specifically, the processor controls the output of the first motor 107 to drive the rotating ring 105 to rotate, thereby driving the rotating plate 106, the disinfection lamp 201, and the reflector to rotate, which in turn drives the disinfection components 200 to rotate, so that the light emitted by all the disinfection lamps 201 is directed away from the human body, avoiding harm and affecting health when directly irradiating the human body at a certain distance. During this process, the disinfection device switches from irradiating disinfection in all directions to directional irradiation.
[0063] Meanwhile, for the disinfection component 200 closest to the human body, the processor controls the output end of the corresponding second motor 204 to rotate, driving the take-up roller 205 to rotate. The pull rope 208 pulls the guide column 206 to slide along the corresponding elongated hole 207, so that the adjacent reflectors 202 move away from each other, and the light-absorbing plate 203 is exposed to the light generated by the disinfection lamp 201 to absorb the light and further reduce the harm to the human body.
[0064] After the person who was near the device leaves, the output of the second motor 204 is controlled to rotate in the opposite direction. The light-absorbing plate 203 is elastic and pulls the two adjacent reflectors 202 so that the two adjacent reflectors 202 move closer to each other to reset. Then the output of the first motor 107 is controlled to rotate in the opposite direction so that the disinfection component 200 rotates to reset. During this process, the disinfection device switches from directional irradiation to irradiating disinfection in all directions.
[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
