Description

[Technical Field]

[0001] The present invention relates to an equipment unit and a patient room. [Background technology]

[0002] In hospital rooms with multiple beds, efforts have been made to reduce the risk of spreading disease to others (see, for example, Patent Document 1). In Patent Document 1, hanging walls or partition walls installed on the ceiling between beds are used to prevent microdroplets from moving to other bed areas. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-033876 Summary of the Invention [Problem to be solved by the invention]

[0004] However, Patent Document 1 requires the installation of a hanging wall in the hospital room, which increases construction costs.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an equipment unit and a hospital room that can prevent droplets from patients from spreading to other areas and can reduce construction costs. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the equipment unit of the present invention is installed in a hospital room and comprises an intake port provided on the wall side near the head of the bed, an exhaust duct connected to the intake port and extending toward the ceiling, a board material arranged to cover at least the front face of the exhaust duct, and medical equipment installed on the board material.

[0007] According to this invention, the equipment unit is equipped with both the exhaust system and the medical equipment, so it can be simply installed against the wall of the patient's room without the need for separate installation. Furthermore, the suction port is located close to the bedside, allowing for efficient absorption of droplets from the patient. This prevents droplets from spreading to other areas and reduces installation costs within the patient's room.

[0008] In the present invention, the suction port may be provided at a position directly above the bed.

[0009] This configuration allows droplets from the patient to be efficiently sucked in and exhausted.

[0010] Furthermore, in the present invention, a filter may be configured to be detachable from the suction port.

[0011] This configuration eliminates the need to replace the filter at a high altitude, making it easier to do so, and even non-professionals such as hospital staff can replace the filter.

[0012] A hospital room according to the present invention includes a plurality of beds, and any one of the above-described equipment units is provided at the head of each of the beds.

[0013] According to this invention, in a multi-bed hospital room, an equipment unit is provided for each bed, so that patient droplets can be exhausted through intake ports provided immediately adjacent to each bed, thereby preventing droplets from spreading within the hospital room.

[0014] In the present invention, an air intake port may be provided on the ceiling surface above the foot of the bed.

[0015] With this configuration, air is supplied from the air supply port of each bed and exhausted from the intake port of the equipment unit located opposite, thereby creating an air circulation route for each bed and preventing droplets from the patient from spreading to other areas.

[0016] In addition, in the present invention, the air supplied from the air supply port may be blown out along the ceiling surface from the feet toward the pillowside.

[0017] This configuration can more effectively prevent droplets from the patient from spreading to other areas. [Effects of the Invention]

[0018] According to the present invention, it is possible to provide an equipment unit and a hospital room that can prevent droplets from a patient from spreading to other areas and can reduce construction costs. [Brief explanation of the drawings]

[0020] Hereinafter, an equipment unit and a hospital room according to an embodiment of the present invention will be described with reference to FIGS.

[0021] As shown in Fig. 1, a hospital room 1 includes a plurality of beds 2, a partition unit 3, an air conditioning system 4, and an equipment unit 10. The hospital room 1 in this embodiment is a four-bed room in which four beds 2 are arranged.

[0022] The hospital room 1 has a floor 11, four walls 12, and a ceiling 13 (see FIG. 3). In this embodiment, the floor 11 has a generally rectangular shape in a plan view. The four walls 12 are erected from four sides of the floor 11. Of the four walls 12, the walls 12 facing each other in one direction are referred to as walls (a pair of walls) 12A and 12B, and the walls 12 facing each other in the other direction are referred to as walls 12C and 12D.

[0023] Here, the horizontal direction in which wall 12A and wall 12B face each other is defined as the X direction (first direction). The horizontal direction in which wall 12C and wall 12D face each other is defined as the Y direction (second direction). Wall 12C is provided with a doorway 15 that leads to a corridor or the like adjacent to wall 12C. Wall 12D is provided with a window 14 that faces the outside.

[0024] A plurality of beds 2 are arranged on the floor 11. In this embodiment, four beds 2 are arranged, but the number of beds can be set appropriately. The four beds 2 are beds 2A, 2B, 2C, and 2D.

[0025] Bed 2 is arranged with the bedside 21 side facing the wall 12. The bedside 21 side of bed 2A and the bedside 21 side of bed 2B are arranged facing the wall 12A. The bedside 21 side of bed 2C and the bedside 21 side of bed 2D are arranged facing the wall 12B.

[0026] Bed 2A and bed 2B are arranged adjacent to each other in the Y direction. Bed 2C and bed 2D are arranged adjacent to each other in the Y direction. Bed 2A and bed 2C are arranged with their foot area 22 sides (opposite side from bedside 21) facing each other. Bed 2B and bed 2D are arranged with their foot area 22 sides (opposite side from bedside 21) facing each other.

[0027] The partition unit 3 is installed between the beds 2 arranged adjacent to each other in the Y direction. In this embodiment, two partition units 3 are installed, but the number of partition units 3 can be set appropriately.

[0028] Of the two partition units 3, the partition unit 3 placed between bed 2A and bed 2B is referred to as partition unit 3A, and the partition unit 3 placed between bed 2C and bed 2D is referred to as partition unit 3B.

[0029] The partition unit 3 reaches from the floor 11 to the ceiling 13. The partition unit 3 is a piece of furniture equipped with a storage section and the like. The partition unit 3A and the partition unit 3B are arranged spaced apart in the X direction. One end of the partition unit 3A in the width direction abuts against the wall 12A. One end of the partition unit 3B abuts against the wall 12B. The partition unit 3 prevents the spread of micro-droplets to adjacent beds 2, and is effective in preventing droplet infection.

[0030] The air conditioning system 4 has an air intake 41, an air supply 42, and an air conditioner (not shown). The air intake 41 is provided on the wall 12 directly above the headboard 21 of the bed 2. Air in the patient room 1 is taken in through the air intake 41, and a portion of the air is returned to the air conditioner. The remaining air that does not return to the air conditioner is discharged to the outside through the air intake 41. Droplets (microdroplets) from the patient are captured before they spread through the air intake 41. A high-performance device is installed in the air conditioner. The high-performance device is composed of a high-performance filter, a medium-performance filter, a UV lamp, etc. The air conditioner removes droplets from the return air taken in through the air intake 41, adjusts the return air with the supplied outside air, and supplies conditioned air into the patient room 1 through the air supply 42.

[0031] The equipment unit 10 will now be described. As shown in FIGS. 2 to 4, the equipment unit 10 is provided along a wall 12 of the hospital room 1. The equipment unit 10 is disposed between the wall 12 and the bed 2.

[0032] The equipment unit 10 comprises a backboard (board material) 51 arranged approximately parallel to the wall 12, an intake port 41 formed in the backboard 51, an exhaust duct 52 connected to the intake port 41, and medical equipment 53 provided on the backboard 51.

[0033] The backboard 51 is made of a wood-grain melamine decorative board. The backboard 51 is wider than the bed 2 and has a height from the floor 11 to the ceiling 13. The backboard 51 is, for example, 1900 mm wide and 2600 mm high.

[0034] An opening 54 is formed in the backboard 51, and the opening 54 serves as the air inlet 41. A perforated metal 55 is attached to the air inlet 41. A filter (not shown) can be attached and detached to the back side of the perforated metal 55. The perforated metal 55 is, for example, 500 mm wide and 650 mm high. The air inlet 41 is provided at a height of 800 mm (center in the height direction) from the floor 11.

[0035] The backboard 51 is fitted with medical equipment 53 such as a lighting fixture 56, an electrical outlet 57, a medical gas outlet 53A, a medical electrical outlet 53B, and a nurse call button 53C.

[0036] A frame material 58 is provided behind the backboard 51 and between it and the wall 12. The frame material 58 is fixed to the wall 12, and the frame material 58 and the backboard 51 are fixed together. Each of these is fixed using a common construction method such as screwing or adhesive.

[0037] An exhaust duct 52 is connected to the air intake 41. The exhaust duct 52 is arranged on the rear surface 51A side of the backboard 51. The exhaust duct 52 is arranged vertically from the air intake 41 toward the ceiling 13. The exhaust duct 52 is made of steel and, for example, has a width of 500 mm and a depth of 140 mm and extends into the ceiling 13. The exhaust duct 52 is connected to an air conditioning duct 61 connected to an air conditioner (not shown) inside the ceiling 13. Note that the exhaust duct 52 may be connected to a duct inside the ceiling 13 that directly exhausts air to the outside. Alternatively, the air conditioning duct 61 inside the ceiling may branch off midway so that some of the return air returns to the air conditioner and the remaining return air is exhausted to the outside.

[0038] The air flow in one bed 2 will now be described.

[0039] Air is supplied toward bed 2 from air intake 42 provided in ceiling 13. The supplied air is fresh air that does not contain viruses contained in droplets. The air supplied toward bed 2 mixed with the patient's droplets is sucked in through intake 41 provided at bedside 21 of bed 2 and exhausted via exhaust duct 52. By creating such an air flow, it is possible to prevent the patient's droplets from spreading to other areas.

[0040] The direction in which the air is blown out from the air inlet 42 will be described.

[0041] As shown in Figures 5 and 6, the number of particles reaching other areas varies depending on the air supply direction (air supply angle). The number of particles reaching the opposite area was measured when the air supply direction was vertically downward (direction A) and at a 45-degree angle downward (direction B), and when air was supplied along the ceiling 13 from the foot 22 toward the pillow 21 (direction C). The results showed that the highest number of particles reached the opposite area when the air supply direction was vertically downward (direction A), followed by a 45-degree angle downward (direction B), and the lowest number of particles reached the opposite area when air was supplied along the ceiling 13 (direction C). Therefore, supplying air from the air supply port 42 along the ceiling 13 in a substantially horizontal direction from the foot 22 of the bed 2 toward the pillow 21 most efficiently captures droplets and prevents them from spreading to other areas.

[0042] The equipment unit 10 of this embodiment is provided in the patient room 1 and includes an intake port 41 provided on the wall 12 side of the headboard 21 of the bed 2, an exhaust duct 52 connected to the intake port 41 and extending toward the ceiling 13, a backboard 51 arranged to cover the front of the exhaust duct 52, and medical equipment 53 provided on the backboard 51. With this configuration, the equipment unit 10 is provided with both an exhaust system and medical equipment 53, so it is sufficient to simply install the equipment unit 10 near the wall of the patient room 1 without having to install either of them. Furthermore, because the intake port 41 is provided immediately adjacent to the headboard 21 of the bed 2, droplets from the patient can be efficiently sucked in. This prevents droplets from the patient from spreading to other areas, and reduces installation costs within the patient room 1.

[0043] Furthermore, since the suction port 41 is provided directly above the bed 2, droplets from the patient can be efficiently sucked in and exhausted.

[0044] In addition, since the filter is detachable from the intake port 41, the filter can be replaced easily without having to be placed at a high place. In addition, even non-professionals such as hospital staff can replace the filter.

[0045] In addition, in a multi-bed hospital room 1, an equipment unit 10 is provided for each bed 2, so patient droplets can be exhausted from intake ports 41 provided immediately adjacent to each bed 2, thereby preventing the droplets from spreading within the hospital room 1.

[0046] Furthermore, air intake ports 42 are provided on the surface of the ceiling 13 above the foot area 22 of the bed 2, and therefore, for each bed 2, air is supplied from the air intake ports 42 and exhausted from the intake ports 41 of the equipment unit 10 arranged opposite. Therefore, an air circulation route can be formed for each bed 2, and droplets from the patient can be prevented from spreading to other areas.

[0047] In addition, the air supplied from the air intake 42 is blown out along the ceiling 13 from the feet 22 toward the pillow 21, which more effectively prevents the patient's droplets from spreading to other areas.

[0048] By installing the equipment unit 10 of this embodiment in the hospital room 1 in this way, a hanging wall is not required in the ceiling 13, which makes it possible to significantly reduce the design and construction costs of the hospital room 1. The equipment unit 10 also reduces the risk of infection in the hospital room 1. Furthermore, the equipment unit 10 can be easily installed in an existing hospital room 1, and can be installed simply by performing duct connection work in the ceiling 13.

[0049] The above describes embodiments of the equipment unit and hospital room according to the present invention, but the present invention is not limited to the above embodiments and can be modified as appropriate within the scope of the gist of the present invention.

[0050] For example, in the above embodiment, the size and height of the suction port 41 are exemplified, but the size and height may be changed as long as droplets from the patient can be collected.

[0051] In the above embodiment, the filter is detachably provided on the rear side of the suction port 41, but the filter may be installed at any position.

[0052] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the United Nations Summit in September 2015. The equipment unit and hospital room of this embodiment can contribute to achieving one of the 17 SDGs, for example, goal 3, "Ensure good health and well-being for all." [Explanation of symbols]
