Description

Technical Field

[0001] The present invention relates to a foldable stretcher that can be folded and compactly stored, and is suitable for use on stairs, curved passages, etc.

Background Art

[0002] As a stretcher for transporting patients or the injured, a stretcher with a cloth stretched between two rods is known. However, there are problems such as being bulky for storage and being difficult to use on stairs or curved passages. Therefore, foldable stretchers suitable for storage and use in narrow places have been proposed.

[0003] For example, Patent Document 1 describes an invention related to a foldable and storable stretcher in which kraft paper and a polyethylene cloth are laminated, and oval cutouts are provided on both left and right sides in the longitudinal direction to serve as gripping portions.

[0004] Also, Patent Document 2 describes an invention related to a simple stretcher using a long rectangular bubble sheet. A plurality of through holes are formed along the longitudinal direction of both side edges, and are used as insertion holes for inserting rod-shaped members or as gripping holes for directly grasping and lifting by hand.

[0005] Also, Patent Document 3 describes an invention related to a foldable stretcher in which a plurality of placement panel members are connected, and a carrying handle is attached to each placement panel member.

[0007] Folding stretchers are kept in ambulances, for example, to transport sick or injured people from the scene to the ambulance via stairs and winding corridors. In such cases, the stretchers often become contaminated with blood, vomit, and excrement from the sick or injured person.

[0008] However, conventional foldable stretchers, such as those described in Patent Documents 1-3, are flat, which means that blood, vomit, and excrement can leak out of the stretcher and contaminate the interior of the ambulance. This has placed a significant burden on paramedics, who must thoroughly clean and disinfect the interior of the ambulance before using it again to prevent infection.

[0009] The present invention solves the above-mentioned conventional problems and provides a foldable stretcher that can prevent the leakage of blood, vomit, excrement, etc. from the stretcher. [Means for solving the problem]

[0010] To solve the above problems, the foldable stretcher of the present invention has a substantially rectangular base, a wall portion that rises up to surround the entire circumference of the base, and a gripping portion formed on opposing longitudinal wall portions of the wall portion.

[0011] Preferably, the wall surface has a connecting portion that connects opposing longitudinal wall surfaces.

[0012] Preferably, the connecting portion is characterized by being adjustable in length.

[0013] Preferably, the connecting portion is characterized by connecting to the wall portion via a carabiner or hook-and-loop fastener. [Effects of the Invention]

[0014] The foldable stretcher of the present invention has a substantially rectangular base, walls that rise up to surround the entire circumference of the base, and gripping parts formed on opposing longitudinal walls. Therefore, even if blood, vomit, excrement, etc. from a sick or injured person placed on the stretcher adheres to it, the walls prevent them from flowing out.

[0015] Furthermore, by having connecting parts that link opposing longitudinal wall sections, the stretcher can stabilize sick or injured people and prevent the longitudinal wall sections, which are prone to leakage of blood, vomit, and excrement, from tipping over.

[0016] Furthermore, because the connecting section is length-adjustable, the length can be adjusted according to the physique of the sick or injured person placed on the stretcher, allowing the wall section to be forcibly raised.

[0017] Furthermore, the connecting section can be connected to the wall section via a carabiner or hook-and-loop fastener, allowing for easy and quick connection of the wall section.

[0018] Thus, according to the present invention, it is possible to provide a foldable stretcher that can prevent the leakage of blood, vomit, excrement, etc. from the stretcher. [Brief explanation of the drawing]

[0019] [Figure 1] This is a perspective view showing a foldable stretcher according to an embodiment of the present invention. [Figure 2] (a) A plan view and (b) A bottom view showing a sheet-like foldable stretcher before the wall sections are formed. [Figure 3] (a) A perspective view showing a foldable stretcher with a connecting section attached, and (b) A plan view showing the connecting section. [Figure 4] (a) A perspective view showing a foldable stretcher with a connecting section attached, and (b) A plan view showing the connecting section. [Modes for carrying out the invention]

[0020] Next, referring to FIGS. 1 to 4, a folding stretcher according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a folding stretcher 100 according to the present embodiment.

[0021] The folding stretcher 100 is formed in a box shape with an open top, and is composed of a bottom surface portion 10, wall surface portions 11, 12, 13, 14, and a plurality of gripping portions 2. The bottom surface portion 10 is substantially rectangular, and wall surface portions rise from all the peripheral edges of the bottom surface portion 10 so as to surround the entire periphery of the bottom surface portion 10. That is, the wall surface portions 11, 12 rise from both sides in the longitudinal direction of the bottom surface portion 10, and the wall surface portions 13, 14 rise from both sides in the short-side direction of the bottom surface portion 10. The space between adjacent wall surface portions (for example, between the wall surface portion 11 and the wall surface 13) is connected without a gap.

[0022] The folding stretcher 100 is formed using a soft material so as to be foldable, and for example, a high-strength vinyl-based sheet such as tarpaulin can be used. Although the folded state is not shown, it can be folded into three or four layers.

[0023] Depending on the softness of the material, the wall surface portions 11, 12, 13, 14 may be inclined outward or inward from the vertical direction, but the wall surface portions may be inclined as long as they rise so as to surround the entire periphery of the bottom surface portion 10.

[0024] Among the wall surface portions, a plurality (eight in the present embodiment) of gripping portions 2 are formed on the opposing longitudinal wall surface portions 11, 12. The gripping portion 2 is a semi-circular ring-shaped member that protrudes upward from the upper end portions of the wall surface portions 11, 12, and it is preferable to use a plastic core material inside.

[0025] Figure 2 shows (a) a plan view and (b) a bottom view of a sheet-like foldable stretcher before the wall sections are formed. The foldable stretcher 100 can be manufactured by raising the entire circumference of the sheet 1 to form the wall sections. That is, the sheet 1 is folded along the fold line 3 to raise the peripheral edge and form the wall sections. At this time, triangular protrusions are created at the corners of adjacent wall sections (for example, wall section 11 and wall section 13), but these can be sewn to the wall sections as shown in Figure 1, thereby maintaining the wall sections in an upright position. It is also preferable to perform seamless processing during sewing to ensure complete waterproofing.

[0026] The gripping parts 2 are pre-attached to the back surface of the sheet 1 with opposing gripping parts 2,2 connected in a ring shape. By connecting the opposing gripping parts 2,2 in a ring shape, the bottom surface 10 can be supported by the connected string-like portion when the opposing gripping parts 2,2 are lifted during use.

[0027] Figures 3 and 4 are, respectively, (a) a perspective view showing a foldable stretcher with the connecting section attached, and (b) a plan view showing the connecting section.

[0028] The foldable stretcher 100 shown in Figure 3 is equipped with connecting parts 4, 4 that connect opposing longitudinal wall sections 11, 12. The connecting parts 4 can be made of a strip-shaped material such as polypropylene cloth tape, and their length can be adjusted using a length adjustment device (not shown) such as a sliding hook (feed hook). Carabiners 5, 5 are attached to both ends of the connecting parts 4, and the connecting parts 4 are connected to the wall sections 11, 12 by inserting the carabiners 5, 5 through the gripping parts 2, 2. In other words, the connecting parts 4 connect the wall sections 11, 12 via the carabiners 5, 5.

[0029] The foldable stretcher 100 shown in Figure 4 is equipped with connecting parts 6, 6 that connect opposing longitudinal wall sections 11, 12. The connecting parts 6 can be made of a strip-shaped material such as polypropylene cloth tape, and their length can be adjusted using a length adjustment device (not shown) such as a sliding hook (feed hook). Hook and loop fasteners 7, 7 are attached to both ends of the connecting parts 6, and the connecting parts 6 are connected to the wall sections 11, 12 by adhering the hook and loop fasteners 7, 7 to the hook and loop fasteners 8, 8 attached to the wall sections 11, 12. In other words, the connecting parts 6 connect the wall sections 11, 12 via the hook and loop fasteners 7, 8.

[0030] The foldable stretcher 100 according to this embodiment has a substantially rectangular bottom surface 10, wall surfaces 11, 12, 13, and 14 that rise up to surround the entire circumference of the bottom surface 10, and gripping parts 2 formed on opposing longitudinal wall surfaces 11 and 12. Therefore, even if blood, vomit, excrement, etc. from a sick or injured person placed on the stretcher adheres to it, the wall surfaces 11, 12, 13, and 14 can prevent them from flowing out.

[0031] Furthermore, by having connecting parts 4 and 6 that connect opposing longitudinal wall sections 11 and 12 within the wall section, it is possible to stabilize sick or injured people on the stretcher and prevent the longitudinal wall sections 11 and 12, which are prone to the leakage of blood, vomit, and excrement, from tipping over.

[0032] Furthermore, because the connecting sections 4 and 6 are length-adjustable, the length can be adjusted according to the physique of the sick or injured person placed on the stretcher, allowing the wall sections 11 and 12 to be forcibly raised.

[0033] Furthermore, by connecting the wall sections 11 and 12 via the carabiner 5 or hook-and-loop fasteners 7 and 8, the wall sections 11 and 12 can be connected easily and quickly.

[0034] Thus, the foldable stretcher 100 according to this embodiment is capable of preventing the leakage of blood, vomit, excrement, etc., from the stretcher.

[0035] Although a foldable stretcher according to an embodiment of the present invention has been described above, the present invention is not limited to the embodiments described above, and various other modifications are possible.

[0036] For example, the configuration and number of gripping parts are not particularly limited, and holes may be formed in the wall surface. Also, the configuration and number of connecting parts are not limited, and may include a combination of a carabiner and hook-and-loop fastener, or a system that fastens to the wall surface with buttons.
