[0005] According to the Emergency Team Infection Prevention Manual Ver. 2.0, ventilation, partitions (protection) between the injured and sick, or the use of isolators are being considered depending on the expected infection route of the infectious disease. For injured or sick people suspected of having an infectious disease, it is desirable to prepare partitions (protection) between the injured and sick and the sick before the emergency team is dispatched, but if the injured or sick person is suspected of having an infectious disease after the emergency team has arrived, there is a problem in that it takes time to prepare. (Non-Patent Document 1)

[0006] The droplet protection equipment needs to be fixed in place to prevent it from shifting or falling off, but there is a problem in that if the droplet protection equipment gets in the way of treating the injured person, the droplet protection equipment must be stored or removed (Patent Document 1).

[0007] The present invention has been made in consideration of these problems, and aims to provide a splash protection device that is easy to put on and take off, shortens preparation time, prevents the attached shield from shifting or falling off, does not interfere with treatment of the injured or sick person, and has an improved effect of capturing splashes generated by the injured or sick person and suppressing their spread. [Means for solving the problem]

[0008] In order to solve the above problem, a splash prevention device for covering the upper body of a lying injured person comprises a back panel and a shield, wherein the back panel comprises a first plate-shaped member having a first connector and a second plate-shaped member having a second connector, and is further configured so that the distance between the first connector and the second connector can be changed by sliding the first plate-shaped member and the second plate-shaped member while they are overlapping, the shield comprises a sheet-shaped member and a frame, the sheet-shaped member is supported by the frame, the frame has arch-shaped support ribs, the support ribs have first and second support members at both ends, the first connector is configured to allow the first support to be detachably attached, and the second connector is configured to allow the second support to be detachably attached, the back panel and the shield are detachable, and the shield is configured to cover the upper body of the injured person by supporting it on the back panel placed on the back of the injured person. [Effects of the Invention]

[0009] The splash prevention equipment according to the present invention is installed between the stretcher or backboard and the mattress with the width of the backboard adjusted to match, and the shield can be attached and detached from the backboard, making it easy to attach the shield and shortening the preparation time, while preventing the attached shield from accidentally shifting or falling off.

[0010] Furthermore, when the support bones are standing up against the backboard and the sheet-like member covers the upper half of the injured person's body, the support bones hold the sheet-like member from the inside and the sheet-like member on the right, left, head and foot sides of the injured person can be rolled up to provide treatment to the injured person, and when the support bones are lying down against the backboard, the sheet-like member can be gathered up at the head side of the injured person so as not to get in the way, and the sheet-like member can be replaced by inserting and detaching the support bones from the sheet-like member.

[0011] In addition, the suction device has a filter placed inside the sheet-like member near the face of the injured person, and the suction fan exhausts the air from which droplets have been removed by the filter to the outside of the sheet-like member, thereby increasing the effectiveness of suppressing the spread of droplets generated by the injured person.The filter also prevents internal contamination of the suction device by droplets, making cleaning and disinfection easier, and the effectiveness of the suction device can be maintained by replacing contaminated filters.

When the frame 400 holds the sheet-shaped member 300 from the inside of the shield 110, the right side of the sheet-shaped member 300 can be rolled up, as shown in Fig. 3. In the same way, the left side, the head side, or the foot side can be rolled up, and the sheet-shaped member 300 can be rolled up as needed to come into contact with the injured person 200 and provide treatment.

[0017] FIG. 4 is a diagram showing an example of the configuration of a splash prevention device. As shown in FIG. 4, the back panel 600 is composed of a first plate-shaped member 610, a first connector 510 attached to the first plate-shaped member 610, a second plate-shaped member 620, and a second connector 530 attached to the second plate-shaped member 620. The first support member 500 can swingably support one end of the support rib F410 and one end of the support rib H420, and the second support member 520 swingably supports the other end of the support rib F410 and the other end of the support rib H420, thereby forming a frame 400. The frame 400 can be attached to the back panel 600 by attaching the first support member 500 to the first connector 510 and attaching the second support member 520 to the second connector 530. In FIG. 4, the support ribs F410 and the support ribs H420 are shown standing upright relative to the back panel 600. The support ribs F410 and H420 are preferably arch-shaped with a straight portion in the center. While multiple support ribs are preferred, the support ribs H420 may be omitted and the device may be configured with only the support ribs F410. The filter 740, which can capture droplets contained in the passing air, is preferably a breathing circuit sterilization filter used in ventilators, for example. The filter fixture 730, which can be detachably attached to the support ribs F410, is preferably positioned inside the sheet-shaped member 300 and near the face of the injured or sick person 200. Alternatively, one end of the suction hose 720 may be positioned inside the sheet-shaped member 300 and near the face of the injured or sick person 200. The suction hose 720 is installed so that one end is connected to the filter 740 and the other end is located outside the sheet-shaped member 300. The suction fan 710 is installed at the other end of the suction hose 720. Alternatively, the suction fan 710 may be installed midway along the suction hose 720. The suction fan 710 exhausts the air inside the suction hose 720, from which droplets have been removed by the filter 740, to the outside of the sheet-like member 300, thereby enhancing the effect of suppressing the spread of droplets generated by the injured person.In addition, the filter 740 prevents internal contamination of the suction device 700 by droplets, making cleaning and disinfection work easier, and the effectiveness of the suction device 700 can be maintained by replacing the contaminated filter 740.

[0018] FIG. 5 shows an example of a shield configuration. The sheet-shaped member 300 is preferably made of a transparent, flexible sheet-like material such as polyethylene, polyester, polypropylene, or vinyl chloride. Alternatively, it is preferably made of a combination of these materials. The through-hole F301 allows the support rib F410 to pass through, and the through-hole H302 allows the support rib H420 to pass through. The through-holes F301 and H302 may be formed by, for example, attaching or welding the two long sides of a long, narrow rectangular member to the sheet-shaped member 300 with an adhesive or a sticky material. The through-hole F301 preferably passes through a straight portion of the center of the support rib F410. The through-hole H302 preferably passes through a straight portion of the center of the support rib H420. Weights RA310, RC312, LA313, and LC315 are attached to the four corners of the sheet-like member 300, weight RB311 is attached between weight RA310 and weight RC312, and weight LB314 is attached between weight LA313 and weight LC315, thereby preventing the sheet-like member 300 from floating up.

[0019] Fig. 6 is a cross-sectional view taken along line AA in Fig. 5. As shown in Fig. 6, the through holes F301 move as the support ribs F410 swing, and the support ribs H420 are pulled and swing at the interval between the through holes F301 and H302, thereby unfolding the sheet-shaped member 300. It is desirable that the through holes F301 be sized to allow the support ribs F410 to be passed through and removed, and that the through holes H302 be sized to allow the support ribs H420 to be passed through and removed, thereby enabling replacement of the sheet-shaped member 300.
