Description

Technical Field

[0001] The utility model relates to the technical field of isolation and protection of infectious diseases, in particular to a double isolation and protection device applied to beds in infectious departments. Background Art

[0002] The Department of Infectious Diseases is a professional department in the hospital that conducts standardized management and modern treatment of infectious diseases. It mainly treats patients with hepatitis, tuberculosis, mumps, rubella, chickenpox, bacillary dysentery, whooping cough, epidemic encephalitis B, epidemic cerebrospinal meningitis, hemorrhagic fever, etc. Isolation is particularly important in the diagnosis and treatment of infectious diseases as the main measure to block the spread of infectious diseases.

[0003] At present, the infectious disease department generally adopts the method of adding isolation buffer wards to block the spread of bacteria and viruses. In order to reduce the risk of cross-infection, the isolation buffer ward usually only accommodates one infectious disease patient, which undoubtedly makes the already tight wards worse, resulting in difficulty in the proper allocation of medical resources and aggravating the difficulty in seeing a doctor and hospitalization.

[0004] In view of this, we propose a double isolation protection device for infection department beds. Utility Model Content

[0008] Furthermore, a light-transmitting isolation film is provided through a window opened on the isolation top plate, a light-shielding isolation top curtain is installed on the light-transmitting isolation film through a third curtain frame, and the light-shielding isolation top curtain can shield the window under the control of a third driving structure.

[0009] Furthermore, a negative pressure suction structure is provided between the hospital bed and the isolation top plate.

[0010] Furthermore, the first driving structure includes a first transmission belt, which is limited into a square ring shape matching the first curtain frame by a plurality of first guide rollers, and one of the first guide rollers serves as an active roller and is connected to a first motor through a first bevel gear assembly.

At the same time, when the light-shielding isolation side curtain and the light-transmitting isolation side curtain are fully unfolded, they can play a double isolation and protection effect, thereby significantly reducing the risk of cross-infection. In addition, since the outer light-transmitting isolation curtain is in a normally open state, even if the inner light-shielding isolation curtain is fully retracted, it will not cause excessive impact on isolation and protection;

[0021] (4) The negative pressure suction structure makes the air pressure in the isolation protection space lower than the external air pressure. Air can only enter from the outside of the isolation protection space and cannot overflow from the inside of the isolation protection space, blocking the air transmission path of viruses and bacteria. While ensuring good ventilation in the isolation protection space, it guides the air to flow in one direction to strengthen the protection of other patients around, thereby reducing the risk of cross infection.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0037] Figures 1 to 11 The first embodiment of the utility model is shown: a double isolation protection device applied to an infectious disease bed, comprising a support structure 2 for detachably connecting to a bed 1, an isolation top plate 3 being arranged on the support structure 2, and a light-shielding isolation side curtain 5 being hung on the bottom surface of the isolation top plate 3 through a first curtain frame 4, and the light-shielding isolation side curtain 5 can be unfolded along the first curtain frame 4 under the control of a first driving structure 6; a light-transmitting isolation side curtain 8 is also hung on the periphery of the first curtain frame 4 through a second curtain frame 7, and the light-transmitting isolation side curtain 8 can be unfolded along the second curtain frame 7 under the control of a second driving structure 9; when the light-shielding isolation side curtain 5 and the light-transmitting isolation side curtain 8 are both in a fully unfolded state, the two can form a double isolation protection space around the bed 1 under the restriction of the isolation top plate 3. Preferably, taking into account the different sensitivities to light of different patients, in order to adjust the top lighting of the isolation protection space, a light-transmitting isolation film 20 is provided on the isolation top plate 3 through the opened window, and a light-shielding isolation top curtain 11 is installed on the light-transmitting isolation film 20 through the third curtain frame 10. The light-shielding isolation top curtain 11 can shield the window under the control of the third driving structure 12.

[0038] like Figure 2 and Figure 6 As shown, in order to make the air outside the isolation protection space flow unidirectionally to the inside to reduce the risk of cross infection, a negative pressure suction structure 14 is also provided between the bed 1 and the isolation top plate 3.

[0039] See also Figures 2 to 5In a specific implementation, the first driving structure 6 includes a first transmission belt 601, and the first transmission belt 601 is limited to a square ring shape matching the first curtain frame 4 by a plurality of first guide rollers 602, and one of the first guide rollers 602 is used as an active roller and is connected to a first motor 604 through a first bevel gear assembly 603. When the first motor 604 rotates forward, it can drive the first guide roller 602 as an active roller to rotate, so as to drive the first transmission belt 601 to run forward, and the active end of the light-shielding isolation side curtain 5 moves with the first transmission belt 601, so that the light-shielding isolation side curtain 5 is gradually unfolded. On the contrary, when the first motor 604 rotates reversely, it can drive the first guide roller 602 as an active roller to rotate, so as to drive the first transmission belt 601 to run in the reverse direction, and the active end of the light-shielding isolation side curtain 5 moves with the first transmission belt 601, so that the light-shielding isolation side curtain 5 is gradually retracted. The second driving structure 9 includes a second transmission belt 905, which is limited to a square ring shape matching the second curtain frame 7 by a plurality of second guide rollers 902, and one of the second guide rollers 902 is used as an active roller and is connected to a second motor 904 through a second bevel gear assembly 603. When the second motor 904 rotates forward, it can drive the second guide roller 902 as an active roller to rotate, so as to drive the second transmission belt 905 to run forward, and the active end of the light-transmitting isolation side curtain 8 moves with the second transmission belt 905, so that the light-shielding isolation side curtain 5 is gradually unfolded. Conversely, when the second motor 904 rotates reversely, it can drive the second guide roller 902 as an active roller to rotate, so as to drive the second transmission belt 905 to run in the reverse direction, and the active end of the light-transmitting isolation side curtain 8 moves with the second transmission belt 905, so that the light-transmitting isolation side curtain 8 is gradually retracted. It is worth mentioning that the light-shielding isolation side curtain 5 and the light-transmitting isolation side curtain 8 are deployed in opposite directions. When medical staff need to diagnose and treat isolated patients, they can control the reverse angular displacement of the first motor 604 and the second motor 904 to open the isolation protection space to a certain degree of operation port, and with the cooperation of the negative pressure adsorption structure, the protection of medical staff can be strengthened to a certain extent. Specifically, in order to improve the stability of motor operation, the first motor 604 and the second motor 904 are both installed horizontally.

[0040] In this embodiment, one end of the light-shielding isolation side curtain 5 is restricted on the first curtain frame 4 as a fixed end, and the other end is movable along the first conveyor belt 601 as an active end, and a plurality of first hooks 605 that can slide along the first curtain frame 4 are also provided on the light-shielding isolation side curtain 5. One end of the light-transmitting isolation side curtain 8 is restricted on the second curtain frame 7 as a fixed end, and the other end is movable along the second conveyor belt 905 as an active end, and a plurality of second hooks 905 that can slide along the second curtain frame 7 are also provided on the light-transmitting isolation side curtain 8.

[0041] like Figures 9 to 11As shown, a storage shell 15 is provided near the window, and a reel 16 of the light-shielding isolation top curtain 11 is rotatably connected in the storage shell 15, and one end of the reel 16 extends out of the storage shell 15 and is used to receive rotational power; a movable frame 17 limited by a third curtain frame 10 is also connected to the end of the light-shielding isolation top curtain 11, and an elastic retractable member 18 is also connected between the movable frame 17 and the storage shell 15. There are two storage shells 15, which are relatively arranged on the left and right sides of the window, and a roll of the light-shielding isolation top curtain 11 is respectively stored in the two storage shells 15 through the reel 16, and the two reels 16 are connected by a reversing transmission assembly 19 to ensure that the two rolls of the light-shielding isolation side curtains 5 can be unfolded toward each other. Specifically, the reversing transmission assembly 19 includes a first belt pulley 1901 and a second belt pulley 1901, the first belt pulley 1901 is connected to one of the reels 16, the second belt pulley 1901 is supported at a position close to the other reel 16 through a bearing seat 1902, and the first arm pulley and the second belt pulley 1901 are transmitted through the belt 1901, a first gear 1903 is arranged on the rotating shaft of the second belt pulley 1901, and a second gear 1904 meshing with the first gear 1903 is arranged on the other reel 16.

[0042] In this embodiment, the third driving structure 12 includes a third motor 1201 and a worm gear assembly 1202, and the output shaft of the third motor 1201 is connected to the near reel 16 through the worm gear assembly 1202. When the third motor 1201 drives the transmission shaft of the worm gear assembly 1202 to rotate forward, the reel 16 near one side rotates forward, and the reel 16 far from one side rotates reversely under the external meshing action of the first gear 1903 and the second gear 1904, at this time, the two rolls of the light-shielding isolation top curtain 11 can be unfolded towards each other under the cooperation of the corresponding elastic retractable member 18; on the contrary, when the third motor 1201 drives the transmission shaft of the worm gear assembly 1202 to reverse, the reel 16 near one side rotates reversely, and the reel 16 far from one side rotates forward under the external meshing action of the first gear 1903 and the second gear 1904, at this time, the two rolls of the light-shielding isolation top curtain 11 can be reversed under the cooperation of the corresponding elastic retractable member 18.

[0043] As shown in the figure, considering the shortage of hospital infection wards during the epidemic period of infectious diseases, it is often necessary to add beds in corridors, stairwells, etc. in practice. The application scenario of the isolation protection bed 1 needs to be frequently switched. In order to make the height of the isolation top plate 3 match different scenarios, the bracket structure 2 includes a clamping seat 201, and a plurality of manually adjustable telescopic rods 202 are connected between the clamping seat 201 and the isolation top plate 3.

[0044] from Figure 3 and Figure 6It can be seen that the negative pressure suction structure 14 includes a negative pressure cavity 1401 arranged on the bottom surface of the isolation top plate 3, the negative pressure cavity 1401 is in a square ring shape, and a plurality of air inlets 1402 are opened on its cavity wall, and a suction pipe 1403 connected to the negative pressure cavity 1401 is also arranged on the isolation top plate 3, and the suction pipe 1403 is connected to the exhaust system outside the ward. In order to kill viruses and bacteria in the air while sucking air, a sterilizing ultraviolet lamp 1404 is also arranged in the negative pressure cavity 1401.

[0045] In summary, the utility model uses the hospital bed 1 as a unit to carry out isolation and protection work for infectious diseases, and forms an independent isolation and protection space based on a single hospital bed 1. Even if it is mixed with other patients in an ordinary ward, it can also avoid cross infection. Therefore, there is no need to add an additional isolation buffer ward, which is conducive to the proper allocation of wards and beds, thereby reducing the waste of medical resources and allowing the infectious department to treat more patients; the bracket structure 2 can be used to quickly assemble the device on a traditional hospital bed 1 without modifying the original structure of the hospital bed 1. It has good versatility and broad application prospects; a double-layer isolation side curtain design is adopted, and the shading isolation side curtain 5 and the light-transmitting isolation side curtain 8 can be independently unfolded or stored, and the patient can fold the shading isolation side curtain 5 according to needs to adjust the lighting Or unfold the shading isolation side curtains 5 to enhance privacy. At the same time, when the shading isolation side curtains 5 and the light-transmitting isolation side curtains 8 are fully unfolded, they can play a double isolation and protection effect, thereby significantly reducing the risk of cross-infection. Moreover, since the outer light-transmitting isolation curtain is in a normally open state, even if the inner light-shielding isolation curtain is completely retracted, it will not cause excessive impact on the isolation and protection. The negative pressure suction structure 14 is used to make the air pressure in the isolation and protection space lower than the external air pressure. Air can only enter from the outside of the isolation and protection space, but cannot overflow from the inside of the isolation and protection space, blocking the air transmission path of viruses and bacteria. While ensuring good ventilation in the isolation and protection space, it guides the one-way inflow of air to strengthen the protection of other patients around, thereby reducing the risk of cross-infection.

[0046] Finally, it should be noted that the technical solution disclosed above is only a preferred embodiment of the present utility model, and it certainly cannot be used to limit the scope of rights of the present utility model. Ordinary technicians in this field can understand that all or part of the processes of the above-mentioned embodiments and equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
