Description

Technical Field

[0001] The utility model relates to the field of ultraviolet disinfection, in particular to an ultraviolet disinfection curtain. Background Art

[0002] Ultraviolet C (UVC) refers to ultraviolet rays with a wavelength of 100-280nm. It is an invisible ultraviolet band commonly used for sterilization and disinfection. Ultraviolet rays mainly play a role in sterilization and disinfection through the following mechanisms: 1) Ultraviolet rays act on the DNA of microorganisms, causing the bacterial DNA to lose its conversion ability and die or lose its reproduction ability; 2) Ultraviolet rays can destroy the amino acids in bacterial proteins and cause the bacterial proteins to photolyze and denature; 3) Ultraviolet rays can reduce the activity of oxidases in bacteria; 4) Ultraviolet rays can ionize oxygen in the air and produce ozone with extremely strong bactericidal effects. Ultraviolet disinfection has many advantages, including strong bactericidal effect, no chemical pollution, no residue, fast disinfection, no odor, no damage to objects, etc. It is the best way to disinfect the surface of equipment.

[0003] Clinically, after a patient is discharged from the hospital or transferred to another department, using ultraviolet light to disinfect the bed and surrounding environment is the most basic and important disinfection method, especially for beds in the intensive care unit (ICU). ICU patients are prone to various drug-resistant bacterial infections. Even after discharge, a large number of pathogens remain on their beds and in the surrounding environment. For the next critically ill patient who is about to stay in the bed, their own immune ability is significantly lower than that of ordinary patients. The invasion of new drug-resistant bacteria will be a serious and fatal blow. When disinfecting, use bed curtains to surround the bed and suspend the ultraviolet lamp above the bed. The main function of the bed curtain is to isolate ultraviolet rays to prevent ultraviolet rays from harming surrounding patients or medical staff. Ordinary bed curtains have the following disadvantages: they can be penetrated by ultraviolet rays or absorb all the ultraviolet rays that irradiate the bed curtains, resulting in the absorption of most of the ultraviolet rays emitted by the ultraviolet lamp except for those that directly irradiate the bed area. In order to increase the amount of light irradiated, a reflective lampshade can be added above the ultraviolet lamp to increase the reflection, but the lampshade also reduces the irradiation range, and sterilization cannot be performed on areas where ultraviolet rays cannot be directly irradiated, such as the edge of the bed, the foot of the bed, the ground, the backlight surface of the equipment, etc.

[0004] Therefore, there is a need for a UV disinfection curtain that can enhance the disinfection effect of UV rays by reflection, increase the range of UV disinfection, and prevent UV rays from leaking out and causing harm to people around. Utility Model Content

[0005] The utility model aims to provide an ultraviolet disinfection curtain to enhance the disinfection effect of ultraviolet rays, increase the disinfection range of ultraviolet rays, and prevent ultraviolet rays from leaking out and causing harm to people around.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An ultraviolet disinfection curtain comprises a base, a plurality of blades, a lifting rope, a hanging rope and a pull rope. The light-facing surface of the blade is made of a light-reflecting material. The light-reflecting material means that when light is irradiated to its surface, its reflection of light is far greater than its absorption of light, especially the reflection of ultraviolet rays. Each blade has at least two leaf holes at corresponding positions, which are usually at both ends of the blade. The lifting rope passes through the leaf holes. The lower end of the lifting rope is fixed to the lowermost blade. The lifting rope is used to store the disinfection curtain. The upper end of the lifting rope is connected to the pull rope. When the disinfection curtain needs to be stored, the pull rope is pulled downward, and the lifting rope moves upward accordingly. The lifting rope drives the lowermost blade to move upward, and the blades are stored one by one, and finally the blades are collected at a position close to the base.

[0008] The base is usually located at the top of the room or the top of the mobile disinfection curtain frame. The upper end of the hanging rope is connected and fixed to the base. The lifting rope and the pull rope are connected inside the base. The base may or may not be provided with a mechanism to restrict the movement of the pull rope according to demand and cost.

[0009] Each blade is provided with at least two pairs of hanging ropes, which are fixed to the long side of each blade. The long side of the blade refers to the position close to the long side of the blade. The length of the two hanging ropes of the blade determines the opening angle of the blade. The opening angle of the blade refers to the angle between the blade and the horizontal plane when the disinfection curtain is in the open state. It is usually an acute angle. The larger the angle, the closer the blade is to the vertical, and the higher the angle of the reflected ultraviolet light. The length of the hanging rope between the blades is a fixed value and cannot be adjusted. According to specific needs, the length of the hanging rope is fixed at the factory. For example, for the disinfection of beds in wards, it needs to be preset according to the height of the bed, the height of the ultraviolet lamp, the width of the disinfection curtain, the range of disinfection required, and other parameters. It can also be set to a blade with a movable angle and its hanging rope scheme;

[0010] The light-facing side of the blade faces the ultraviolet lamp, and the ultraviolet rays released by the ultraviolet lamp can be reflected by the blade to the disinfection area. The light-facing side of the blade refers to the side with ultraviolet reflection ability facing the ultraviolet lamp when working, and the opposite side is the backlight side.

[0011] Furthermore, in order to make full use of the ultraviolet rays in the lower part of the disinfection curtain, while reducing the number of blades and reducing costs, the disinfection curtain is composed of a blade curtain and a plane curtain. The blade curtain in the upper part of the disinfection curtain is composed of the above-mentioned several blades, and the lower part is a plane curtain. The plane curtain refers to a curtain composed of a complete plane. The light-facing surface of the plane curtain is made of a light-reflecting material. The light-reflecting material means that when light is irradiated to its surface, its reflection of light is far greater than its absorption of light. The upper end of the plane curtain is connected to the blades above it.

[0012] Furthermore, in order to make the flat curtain as easy to store as the blade curtain, a plurality of transverse bones are provided on the backlight surface of the flat curtain, and the backlight surface refers to the side opposite to the light-facing surface. The transverse bones are connected and fixed to the backlight surface of the flat curtain, and each transverse bone has at least two transverse bone holes corresponding to the positions of the blade holes. A transverse bone rope passes through the transverse bone holes. The position corresponding to the blade hole refers to a position in which the lifting rope or the transverse bone rope passing through the blade hole and the transverse bone hole can naturally droop. The upper end of the transverse bone rope is connected to the lifting rope, and the connection between the lifting rope and the lowest blade is disconnected, and the lower end of the transverse bone rope is connected and fixed to the lowest transverse bone.

[0013] Furthermore, the light-facing surface of the blade and the light-facing surface of the flat curtain are made of aluminum foil, silicone oil or titanium dioxide, so as to reflect more ultraviolet rays while absorbing as little ultraviolet rays as possible.

[0014] Furthermore, in order to focus the reflected ultraviolet rays on the area to be disinfected, such as a hospital bed, the opening angles of the blades increase from top to bottom. When the blades are located below the ultraviolet lamp, vertically arranged blades can be used, or flat curtains can be used instead.

[0015] In order to more effectively disinfect the area to be disinfected and prevent ultraviolet rays from spilling out, the number of the disinfection curtains is several, and the disinfection target area can be surrounded from all directions.

[0016] The utility model has the beneficial effect of placing an ultraviolet disinfection curtain provided by the utility model around the area to be disinfected, or replacing the traditional partition curtain originally used for shading, and the ultraviolet rays that have not acted on the disinfection area can be reflected back to the area to be disinfected through the ultraviolet reflective blades above, and can even be reflected to the area that the original ultraviolet lamp cannot irradiate, so that the utilization rate of ultraviolet rays is greatly improved, and the effect of sterilization and disinfection is significantly increased. Especially when used for bed disinfection, it can not only enhance the disinfection effect of the original disinfection range, but also reflect ultraviolet rays to multiple areas such as both sides of the bed edge, the foot of the bed, and the bed bottom lamp, so as to carry out comprehensive sterilization and disinfection.

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-6 The utility model provides an ultraviolet disinfection curtain, including a base 11, a plurality of blades 12, a lifting rope 14, a hanging rope 15, and a pull rope 16. The light-facing surface of the blade 12 is made of a light-reflecting material. The light-reflecting material means that when light is irradiated to its surface, its reflection of light is far greater than its absorption of light, especially the reflection of ultraviolet light. Ultraviolet light is essentially an electromagnetic wave, commonly known as invisible light. In the utility model, "light" refers to electromagnetic waves, especially electromagnetic waves with a wavelength close to visible light. Each blade 12 There are at least two leaf holes 13 at corresponding positions, which are usually at the two ends of the blade 12. The lifting rope 14 passes through the leaf holes 13. The lower end of the lifting rope 14 is fixed to the lowermost blade 12. The lifting rope 14 is used to store the disinfection curtain. The upper end of the lifting rope 14 is connected to the pull rope 16. When the disinfection curtain needs to be stored, the pull rope 16 is pulled downward, and the lifting rope 14 moves upward accordingly. The lifting rope 14 drives the lowermost blade 12 to move upward, and the blades 12 are stored one by one, and finally the blades 12 are collected at a position close to the base 11;

[0028] The base 11 is usually located at the top of the room or the top of the movable disinfection curtain frame. The uppermost end of the hanging rope 15 is connected and fixed to the base 11. The lifting rope 14 and the pull rope 16 are connected inside the base 11. A mechanism for limiting the movement of the pull rope 16 may or may not be set in the base 11 according to demand and cost.

[0029] Each blade 12 is provided with at least two pairs of hanging ropes 15, and the hanging ropes 15 are fixed to the long side of each blade 12. The long side of the blade 12 refers to the position close to the long side of the blade 12. The length of the two hanging ropes 15 of the blade 12 determines the opening angle of the blade 12. The opening angle of the blade 12 refers to the angle between the blade 12 and the horizontal plane when the disinfection curtain is in the open state, which is usually an acute angle. The larger the angle, the closer the blade 12 is to the vertical, and the higher the angle of the reflected ultraviolet light. The length of the hanging rope 15 between the blades 12 is a fixed value and cannot be adjusted. According to specific needs, the length of the hanging rope 15 between the blades 12 is fixed at the factory. For example, when used for disinfection of beds in wards, it needs to be preset according to parameters such as the height of the bed, the height of the ultraviolet lamp, the width of the disinfection curtain, the range of disinfection required, etc. It can also be set to a blade 12 with a movable angle and its hanging rope 15 scheme;

[0030] The light-facing surface of the blade 12 faces the ultraviolet lamp, and the ultraviolet rays released by the ultraviolet lamp can be reflected by the blade to the disinfection area. The light-facing surface of the blade 12 refers to the side with a high ultraviolet reflection property when working.

[0031] In order to make full use of the ultraviolet rays in the lower part of the disinfection curtain, reduce the number of blades 12 and reduce costs, the disinfection curtain is composed of a blade curtain and a plane curtain 21. The blade curtain in the upper part of the disinfection curtain is composed of the above-mentioned blades 12, and the lower part is a plane curtain 21. The plane curtain 21 refers to a curtain composed of a complete plane. The light-facing surface of the plane curtain 21 is made of a light-reflecting material. The light-reflecting material means that when light is irradiated to its surface, its reflection of light is far greater than its absorption of light. The upper end of the plane curtain 21 is connected to the blades 12 above it.

[0032] In order to make the plane curtain 21 as easy to store as the blade curtain, a plurality of transverse bones 22 are provided on the backlight surface of the plane curtain 21. The backlight surface refers to the side opposite to the light-facing surface. The transverse bones 22 are connected and fixed to the backlight surface of the plane curtain 21. Each transverse bone 22 has at least two transverse bone holes 23 corresponding to the positions of the blade holes 13. A transverse bone rope 24 passes through the transverse bone holes 23. The position corresponding to the blade hole 13 refers to a position in which the lifting rope 14 or the transverse bone rope 24 passing through the blade hole 13 and the transverse bone hole 23 can naturally droop. The upper end of the transverse bone rope 24 is connected to the lifting rope 14, and the connection between the lifting rope 14 and the lowest blade 12 is disconnected. The lower end of the transverse bone rope 24 is connected and fixed to the lowest transverse bone 22.

[0033] The light-facing surface of the blade and the light-facing surface of the flat curtain 21 are made of aluminum foil, silicone oil or titanium dioxide, with the purpose of reflecting more ultraviolet rays while absorbing as little ultraviolet rays as possible. They can also be made of other materials that do not absorb ultraviolet rays and can highly reflect ultraviolet rays, usually using a coating process.

[0034] In order to focus the reflected ultraviolet rays on the area to be disinfected, such as a hospital bed, the opening angle of the blades 12 increases from top to bottom. When the blades 12 are located below the ultraviolet lamp, vertically arranged blades 12 can be used, or flat curtains 21 can be used instead.

[0035] In order to more effectively disinfect the area to be disinfected and prevent ultraviolet rays from spilling out, the number of the disinfection curtains is several, and the disinfection target area can be surrounded from all directions.

[0036] The ultraviolet disinfection curtain provided by the utility model is placed around the area to be disinfected, or replaces the traditional partition curtain originally used for shading. The ultraviolet rays that have not acted on the disinfection area can be reflected back to the area to be disinfected through the upper blades 12 that can reflect ultraviolet rays, thereby increasing the number of ultraviolet rays and thus increasing the disinfection effect. It can even be reflected to areas that the original ultraviolet lamp cannot irradiate, thereby greatly improving the utilization rate of ultraviolet rays and significantly increasing the effect of sterilization and disinfection. Especially when used for bed disinfection, it can not only enhance the disinfection effect of the original disinfection range, but also reflect ultraviolet rays to multiple areas such as both sides of the bed edge, the foot of the bed, and the bed bottom lamp, so as to carry out comprehensive sterilization and disinfection.

[0037] like Figure 5 , Figure 6 As shown, Figure 5 This is a schematic diagram of the effective amount of ultraviolet rays when using ordinary bed curtains for ultraviolet disinfection. Except for the ultraviolet rays directly irradiated above the bed, the rest of the ultraviolet rays are wasted. After the disinfection curtain of the utility model is prepared, Figure 6 As shown, most of the wasted ultraviolet rays can be reflected above the bed to enhance the disinfection effect above the bed. At the same time, the ultraviolet rays can also be reflected to the edge of the bed, the foot of the bed, the bottom of the bed and other areas to carry out comprehensive sterilization and disinfection of the bed and the surrounding environment.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
