Description

Technical Field

[0001] The present invention relates to a shield for preventing droplet infection, for example, for blocking between a bedridden patient and the external environment and achieving mutual protection between the patient and the external environment.

Background Art

[0002] Under the spread of the novel coronavirus, various measures are being taken in medical institutions. Among them, in order to prevent the spread of the virus due to the proximity between hospitalized patients and surrounding persons including medical staff, it has been proposed to cover the patients on the bed with a partition sheet, board, cover, etc. (see, for example, Patent Documents 1 and 2). By the way, in medical institutions equipped with certain facilities such as hospitals, the installation of shield members such as the aforementioned sheets and boards can be carried out relatively easily. However, when looking at evacuation shelters and the like in the event of disasters that have occurred frequently recently, there are hardly any suitable shield members for dealing with the case of accepting such patients. In addition, in the case of shield members using acrylic boards or the like in medical institutions, at present, they are reused under sufficient disinfection each time they are used, and at present, a considerable amount of labor is required for that.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention has been made in recognition of such a background, and for example, even in a temporary evacuation facility or the like, it is possible to simply block off the affected person from the outside. Also, although the overall weight before assembly is light, after assembly it has sufficient strength, and furthermore, it can be extremely easily transported, stored, and assembled. Moreover, when disposing of the members after use, it is an object to develop a novel shield for preventing droplet infection that causes as little environmental impact as possible.

Means for Solving the Problems

[0005] First, the shield for preventing droplet infection according to claim 1 is A shield for preventing droplet infection in which a three-dimensional frame-shaped frame is constituted by pillar elements provided to be self-supporting and a plurality of horizontal crossbar elements that connect these pillar elements to each other, and a shield sheet is placed on this frame so as to moderately block the inside, Both the pillar elements and the horizontal crossbar elements are paper-made cylindrical bodies, Further, the pillar elements are rectangular prism-shaped square tubes, and the horizontal crossbar elements are circular cylinder-shaped with a circular cross-section, And the connection structure for connecting these pillar elements and horizontal crossbar elements to each other is a fitting connection in which circular hole-shaped insertion holes are provided in the side plates of the pillar elements, and the ends of the horizontal crossbar elements are fitted into these insertion holes for connection and moreover, the column element is in a state where four side plates pasted with sacks are folded in a flat-folded state in the starting state, when forming this folded column element into a three-dimensional column shape, the side plates are raised so that adjacent side plates are in an orthogonal state from the flat-folded flat state, and the whole is made to exhibit a cylindrical shape. At the same time, the end flaps provided at both ends of the side plates are engaged so as to be stacked on top of each other, and a rectangular tubular shape with both upper and lower ends closed is formed three-dimensionally A shield for preventing droplet infection, characterized in that.

[0006] Also, the shield for preventing droplet infection according to claim 2 In addition to the requirements described in claim 1 record the pillar elements are applied in four numbers, and they are all formed in the same dimensions, and the cylindrical horizontal crossbar elements that connect these pillar elements are also all formed in the same dimensions, and the three-dimensional frame-shaped frame is characterized in that it is configured in a rectangular parallelepiped shape. And by using the configurations described in these respective claims as means, the above problems are solved.

Effects of the Invention

[0007] ​ First, according to the invention described in claim 1, since both the column element and the crossbar element are paper-made cylindrical bodies, when distributing them as a so-called kit that groups together all the members necessary for assembling a single droplet infection prevention shield, the weight of one kit is light and it is easy to carry, and it also becomes easy to store (stockpile) in an emergency evacuation facility. Further, since the column element and the crossbar element are made of paper, when incinerating and disposing of them after use, they can be discarded with almost no environmental load. Also, since the connection between the column element and the crossbar element is a fitting connection, when assembling them, no tools are required and they can be easily assembled manually by anyone, anywhere, at any time. Moreover, according to the present invention, since the column element is in the shape of a square cylinder while the crossbar element is in the shape of a cylinder, the distinction between the two members can be immediately judged from the appearance, there is no confusion in selecting the members, and the assemblability is improved. Also, the insertion holes formed in the column element, that is, the holes for fitting the crossbar element, are circular, and the durability as the hole shape is improved. Further, according to the present invention, since the column element is in a state where four side plates pasted with sacks are folded in a flat-folded state in the starting state, the column element does not take up much space in the starting state, and as the loading state of the members for one kit, it can be more compactly accommodated, further improving the transportability and storage property.

[0008] Also according to claim 2 According to the invention described, since four column elements are provided and the three-dimensional frame-shaped frame is configured in a rectangular parallelepiped shape, a very simple three-dimensional shape as a frame is obtained. In addition, since the column elements and the crossbar elements are all formed in the same dimensions for each member, the commonization of the members can be achieved, and the constituent members of the droplet infection prevention shield for one kit are more compactly grouped together, contributing to the improvement of transportability, storability, etc. Conversely, if the sizes and lengths of each member are different, it becomes difficult to compactly group the members of one kit as a load shape, and it also becomes difficult to transport and store them. Also, when assuming use during an emergency disaster, although it may be possible to assemble in advance through training or the like, even in that case, if the dimensions are the same for each type of member, it is easy to return to the original load shape and there is little worry of losing the members.

Embodiments for Carrying Out the Invention

[0010] The embodiments for carrying out the present invention include, as one of them, those described in the following examples, and further include various methods that can be improved within the technical idea thereof.

Examples

[0011] The shield 1 for preventing droplet infection of the present invention is configured by a three-dimensional frame-shaped frame F formed by column elements 2 provided in a self-supporting number and a plurality of horizontal cross member elements 3 that connect these column elements 2 to each other. A shield sheet 5 is placed on this frame F so as to shield the inside thereof. The column element 2 and the horizontal cross member element 3 are both paper-made cylindrical bodies, and the connection structure 4 that connects the column element 2 and the horizontal cross member element 3 is a fitting connection. Here, the above-mentioned "loose shielding" will be described together with the shield sheet 5 described later. Since the column element 2 and the crossbar element 3 are both made of paper cylinders in this way, the shield 1 for preventing droplet infection is extremely lightweight, and moreover, it can be disposed of (incinerated) with almost no burden on the environment even after use. Moreover, since the connection structure 4 between the column element 2 and the crossbar element 3 is a fitting, no tools are required for assembling the frame F, and it can be easily assembled. Also, because it is lightweight, it can be easily carried and stored.

[0012] Also, a plurality of column elements 2 and a plurality of crossbar elements 3 are provided, but each member is formed in the same size and length for each member. When using the shield 1 for preventing droplet infection, the user M puts his / her upper body (head) into the frame F from one side of the assembled frame F (see Fig. 1), and this side is defined as the entry surface FF. Also, the rear surface (inner side) facing the entry surface FF is defined as the rear surface FB, the right surface facing the entry surface FF is defined as the right surface FR, and the left surface facing the entry surface FF is defined as the left surface FL. Also, the upper surface of the frame F in the installed state is defined as the upper surface FU. Incidentally, the lower part of the entry surface FF does not require the crossbar element 3 because the user M puts his / her upper body (head) into the entry surface FF and assumes a lying posture. Hereinafter, the column element 2, the crossbar element 3, and the connection structure 4 will be specifically described.

[0013] First, as shown in FIG. 1 as an example, the column element 2 is a columnar member in the shape of a rectangular prism with a rectangular cross-section. In the initial state during circulation and storage, the four side plates 21 pasted with sacks are in a flat-folded form. That is, the column element 2 forms a blank shape in which the four side plates 21 are connected via fold lines 22 in the initial state, and the side plates 21 (edges) located at the connection ends of this blank material are pasted with sacks. And to three-dimensionally form the folded column element 2 into a column shape, it is raised from the flat-folded flat state so that adjacent side plates 21 are substantially orthogonal to each other, and three-dimensionally formed to present an overall cylindrical shape. As shown in FIG. 2 as an example, the end flaps 23 provided at both ends of the side plate 21 are engaged with each other to obtain the column element 2 which is a square columnar member with both upper and lower ends closed. In this way, the column element 2 is provided in a flat-folded state in the initial state. Therefore, when it is distributed as a so-called kit that groups together the members necessary to assemble one droplet infection prevention shield 1, it becomes extremely compact as a packaged form that groups together the necessary members, is extremely easy to carry, and only requires a narrow space for storage, making it excellent in convenience.

[0014] Hereinafter, the end flap 23 will be described. The end flap 23 is provided at both the upper and lower ends of the column element 2 as described above. In this embodiment, the upper end has a structure that is closed in a lid shape, for example, as shown in FIG. 2 above. On this upper end side, it includes a pair of folded inner flaps 23a provided oppositely, a lid flap 23b that pushes these inward, and an insertion flap 23c provided in a connected manner on the free end side of this lid flap 23b. On the other hand, at the other end, in this embodiment, the lower end of the column element 2 has a structure that forms a closed bottom, for example. A first push-in flap 23d is provided on one side of the rectangular end opening, middle folded flaps 23e are provided oppositely on the two adjacent sides, and a pressing flap 23f is formed on the remaining side, that is, the side opposite to the first push-in flap 23d. Of course, the configuration of the end flap 23 of the column element 2 may be the same for both ends, and for the closing configuration, other known configurations may be applied.

[0015] Also, as an example, as shown in FIGS. 2 and 1, this column element 2 is provided with circular insertion holes 25 for connecting the horizontal crossbar elements 3, and this forms part of the connection structure 4. Here, in this embodiment, the horizontal crossbar element 3 connects a total of four column elements 2. Since two column elements 2 are arranged above and below the entry surface FF, right surface FR, left surface FL, and rear surface FB of the frame F, each column element 2 has two insertion holes 25, one at each of two locations on the inner surface of the frame adjacent to each other at the upper and lower ends, for a total of four insertion holes 25 up and down. Here, the two insertion holes 25 formed at the upper and lower parts of one column element 2 are formed with different heights to avoid interference between the horizontal crossbar elements 3 that are cross-fitted into the column element 2. Note that since the entry surface FF of the frame F is the side where the user M puts in the upper body (head), as described above, the lower horizontal crossbar element 3 is unnecessary. Therefore, it is not necessary to form the insertion holes 25 for fitting the horizontal crossbar element 3 at the lower part of the entry surface FF. Of course, in order to make all the column elements 2 common, the insertion holes 25 may be formed even if they are unnecessary.

[0016] Furthermore, the pillar element 2 is provided with one element piece of the surface fastener 26 for fastening the shield sheet 5 above it. In this embodiment, one element piece of the surface fastener 26 is provided at two locations on the upper outer side of each pillar element 2, for a total of eight locations. Specifically, the letters "A" to "D" are displayed on the element piece of the surface fastener 26, which is for improving the fastening property of the shield sheet 5 described later, and this display is defined as the sheet attachment display M1. That is, in this embodiment, as shown in FIG. 1 above, as the letters of the sheet attachment display M1, "A" is attached to two locations above the pillar element 2 forming the entry surface FF, "B" is attached to two locations above the pillar element 2 forming the rear surface FB, "C" is attached to two locations above the pillar element 2 forming the right surface FR, and "D" is attached to two locations above the pillar element 2 forming the left surface FL.

[0017] Also, in each pillar element 2, numbers from "1" to "7" are displayed in the vicinity of the insertion hole 25 into which the horizontal crossbar element 3 is inserted. This is a display for making it easier to understand the fitting of the horizontal crossbar element 3, and this display is defined as the fitting display M2. That is, when inserting the horizontal crossbar element 3 into the pillar element 2, the pillar elements 2 are arranged opposite to each other such that the numbers (the same numbers) of the fitting display M2 described on one side surface of the pillar element 2 face each other, and the horizontal crossbar element 3 is inserted between them. In this way, in this embodiment, by attaching the sheet attachment display M1 using letters and the fitting display M2 using numbers to each pillar element 2, even if all the plurality of pillar elements 2 are formed in the same dimensions, the orientation of the pillar element 2 during fitting and the location where the pillar element 2 is arranged in the frame F are extremely easy-to-understand structures.

[0018] Next, the horizontal crossbar element 3 will be described. The horizontal crossbar element 3 is a member for connecting a plurality of vertically erected pillar elements 2, and is a so-called horizontal cross-member arranged orthogonally to the pillar element 2. Here, in this embodiment, a cylindrical member with a circular cross-section is applied as the horizontal crossbar element 3, and the end 31 of this member is left in a cut-off state, which is because the end 31 is to be accommodated in the pillar element 2 in a connected state. Further, as described above, the plurality of horizontal bar elements 3 are all formed in the same size and length and are all used as common members. Therefore, there is no dedicated member for connecting specific column elements 2 to each other, and thus the frame F has a structure that is easy to assemble.

[0019] Thus, in this embodiment, since the column element 2 and the horizontal bar element 3 are formed in exactly the same dimensions for each member, when the members of one set of the droplet infection prevention shield 1 are circulated as a kit, the package form thereof becomes extremely compact, and it becomes even easier to carry out transportation, storage, etc. Further, even when, for example, after actually assembling in a disaster prevention training or the like and then returning to the original package form, it is possible to prevent the loss of the members for one kit.

[0020] Also, while the column element 2 is a square tube, the horizontal bar element 3 is a circular tube. Since the shapes of the respective members are different, it is possible to clearly distinguish at a glance which element the member is, and the frame F has an even easier-to-assemble structure. Of course, the configuration in which the members can be clearly distinguished from the appearance in this way is a structure that can be easily assembled by anyone, in other words, even by relatively lower-grade children, and is an extremely preferable configuration as a shield member assuming an emergency evacuation.

[0021] And the column element 2 and the horizontal bar element 3 are assembled in this way to form the frame F in a three-dimensional frame shape. Hereinafter, the overall configuration of the frame F together with this connection structure 4 will be described. As described above, the column element 2 is in a flat-folded state in the initial state, and thus is formed into a square column shape in a three-dimensional shape. For this, each side plate 21 in the folded state is formed in a three-dimensional shape so as to exhibit a square tube shape. Thereafter, the end flaps 23 provided at both ends of the side plate 21 are stacked to form a three-dimensional square tube-shaped column element 2 with both ends closed.

[0022] Then, for the column element 2 having such a square tube shape, cylindrical horizontal crossbar elements 3 are fitted into the respective insertion holes 25, and as a result, a frame F forming a rectangular parallelepiped-shaped framework is configured. Here, in this embodiment, since numbers (here, "1" to "7" as described above) as fitting display M2 are displayed near the insertion holes 25 in the column element 2, the column elements 2 are arranged opposite to each other so that the fitting display M2 faces each other, and by inserting the horizontal crossbar element 3, which is a common member, therebetween, the frame F can be easily assembled. Also, for this reason, the frame F can be assembled without hesitation as to which position the column element 2 is in the frame F. Note that the fitting display M2 does not necessarily have to be a number, and for example, hiragana, katakana characters, etc. may also be used. Also, in the assembled state where the frame F is formed three-dimensionally, for the entry surface FF into which the user M puts the upper part of the body as described above, no horizontal crossbar element 3 is provided at the lower part.

[0023] Incidentally, the inner space of the frame F is formed to be approximately 700 mm in width, approximately 700 mm in depth, and approximately 750 mm in height as an example, and this size is such that the user M who has put the upper part of the body into the frame can extend the arms upward in a supine position, and it has a width that is not likely to cause a feeling of compression.

[0024] Then, for such a frame F, a shield sheet 5 is placed thereon to constitute the splash infection prevention shield 1. As the shield sheet 5, for example, a transparent material made of vinyl chloride can be applied and can be formed to be approximately 0.1 mm thick. This shield sheet 5 includes, as an example, an elongated vertical covering sheet 51 that covers from the entry surface FF of the frame F to the upper surface FU and then to the rear surface FB as shown in FIG. 1 above, and horizontal covering sheets 52 that separately cover the left surface FL and the right surface FR of the frame F. Here, when distinguishing the horizontal covering sheets 52 on the left and right, the one covering the right surface FR of the frame F is designated as 52R, and the one covering the left surface FL is designated as 52L. Each shielding sheet 5 is provided with other element pieces of the surface fastener 26 for attaching this to the pillar element 2 as described above, and the sheet attachment indication M1 is also displayed near the element pieces of the surface fastener 26.

[0025] Therefore, in order to attach the shielding sheet 5 to the frame F, it is fastened by aligning the sheet attachment indications M1 such as alphabets (here, alphabets "A" to "D") written on the pillar element 2 and the shielding sheet 5. Specifically, with respect to the frame F three-dimensionally formed as described above, first, while covering the vertical covering sheet 51 from the entry surface FF to the upper surface FU and further to the opposing rear surface FB, the surface fasteners 26 having the same sheet attachment indication M1 are fastened together. That is, in this embodiment, when covering the entry surface FF of the frame F, it is fastened by aligning the pillar element 2 with "A", which is the sheet attachment indication M1 attached to the vertical covering sheet 51 covering the entry surface FF. Also, when covering the rear surface FB of the frame F, it is fastened by aligning the pillar element 2 with "B", which is the sheet attachment indication M1 attached to the vertical covering sheet 51 covering the rear surface FB. On the other hand, the horizontal covering sheets 52R and 52L are attached separately so as to cover the right surface FR and the left surface FL of the frame F respectively. At this time as well, it is fastened while aligning "C" and "D", which are the same sheet attachment indication M1 attached to the upper part of the pillar element 2 and the horizontal covering sheets 52R and 52L. Thereby, the frame F is covered such that all five surfaces other than the bottom surface are covered with the shielding sheets 5. Regarding the sheet attachment indication M1, it is not necessarily required to use alphabets, and various symbols, characters, numbers, etc. different from the fitting indication M2 can be applied.

[0026] The thus assembled droplet infection prevention shield 1 is installed on a floor surface covered with an appropriate mat or the like or a placement surface B such as a simple bed. The user M enters from the entry surface FF of the frame F, and while lifting the lower front part of the vertical covering sheet 51 covering this, puts in the head and a part of the upper body, and takes a lying posture such as lying on the back. And in this state, as an example, as shown in FIG. 1 above, by obliquely hanging the lower part of the sheet covering the entry surface FF on one's own legs, the entry surface FF is covered with the sheet, and a loose barrier from the outside is made to prevent droplet infection.

[0027] Here, as described above, since the vertical covering sheet 51 and the horizontal covering sheet 52 are separated, and in the use state, the lower front part of the vertical covering sheet 51 covering the entry surface FF is inclined, a gap is formed between the vertical covering sheet 51 and the horizontal covering sheet 52. Also, since the fixing of the shield sheet 5 to the frame F is partial, a gap is also formed between the frame F and the shield sheet 5. For this reason, the space inside the frame F is not completely blocked from the outside, and the non-closed state inside the frame F is maintained, and there is no worry that the user M with the head inside will suffer from oxygen deficiency. As described above, the droplet infection prevention shield 1 of the present invention does not completely isolate the user M who has entered inside, but is in a state of communicating with a somewhat gap with the outside. That is, the droplet infection prevention shield 1 of the present invention mainly prevents droplets when the user M with the head inside the shield coughs or talks with medical staff outside, and does not completely block the virus. Also, for this reason, it is called "loose barrier". In addition, after use as a shield, from the viewpoint of hygiene and safety, it is not preferable to reuse it for other users M, and it will be discarded. However, since the component members of the frame F of the droplet infection prevention shield 1 of the present invention are basically flammable, it is possible to perform combustion disposal with the minimum environmental load.

[0028] 〔Other embodiments〕 The present invention is based on the above-described embodiments as a basic technical idea, but the following modifications can be further considered. First, in the above-described basic embodiment, the frame F was formed in a rectangular parallelepiped shape, but the frame F does not necessarily have to be formed in a rectangular parallelepiped shape. That is, since the width of a person's head is narrower than the shoulder width, in consideration of this, for example, as shown in FIG. 3, it is also possible to form the frame F in a trapezoidal shape (isosceles trapezoid) or a triangular shape in plan view.

[0029] In addition, the connection structure 4 between the column element 2 and the cross-bar element 3 can adopt a structure that not only stops at the connection by simply fitting into the insertion hole 25 but also more actively reinforces the fitting state. Specifically, for example, as shown in FIG. 4(a), on the side plate 21 of the column element 2 opposite to the side plate 21 where the insertion hole 25 is provided, it is possible to project the receiving flap 41 inward within the frame. In this case, by folding and inserting the receiving flap 41 into the end portion 31 of the cross-bar element 3 inserted through the insertion hole 25, the folded receiving flap 41 is locked in a fitted state with respect to the end portion 31 of the cross-bar element 3, and the connection between the column element 2 and the cross-bar element 3 is further strengthened. Also, at this time, a plurality of substantially radial split slits 42 are formed in the side plate 21 facing the insertion hole 25, whereby the receiving flap 41 is formed, and the receiving flap 41 is pushed inward at the intersection center to achieve locking with the cross-bar element 3. Further, at this time, for example, as shown in FIG. 4(a), it is preferable to form the split slits 42 in a cross shape and to form a shape-retaining guide slit 43 such as an arc shape on the base side of the receiving flap 41. This makes it less likely for the bent portion to be linear when the receiving flap 41 is bent inward, and it is easier to exhibit a bent state, that is, a self-standing state.

[0030] Furthermore, to make such a connection structure 4 even stronger, as an example, as shown in FIG. 4(b), a fitting plug 44 made of a paper tube or the like with a smaller diameter than the inner diameter of the horizontal bar element 3 is prepared. After pushing the receiving flap 41 into the end portion 31 of the horizontal bar element 3, it is preferable to press-fit the fitting plug 44 further inside thereof. Thereby, the end portion 31 of the horizontal bar element 3 is more firmly connected to the column element 2 by maintaining the inward-expanded state by the fitting plug 44 of the receiving flap 41. In addition, such a configuration of the receiving flap 41 can also be applied to the insertion hole 25 side.

[0031] Furthermore, in the above-described basic embodiment, the horizontal bar element 3 is formed of a cylindrical paper tube. On the other hand, the horizontal bar element 3 can also be formed of a square tube-shaped paper tube similar to the column element 2, as shown in FIG. 5, for example. to However, this is a reference example related to the present invention. In the case of the reference example shown in FIG. 5 above, the horizontal bar element 3 can also be in a flat folded state in the starting state. When all members are provided and distributed in the market in a package, it can be provided as a more compact loading form, making storage and accommodation easier. Also, as the connection structure 4 in this case, as shown in the partial enlarged view of FIG. 5 above, the insertion slit 45 formed in the column element 2 can be applied. Also, a locking tongue piece 46 that can protrude outward is formed on the side surface of the horizontal bar element 3, and this is made to protrude outward before fitting, and by fitting it into the column element 2, it is also possible to lock the free end of the locking tongue piece 46 inside the column element 2. Of course, the connection structure 4 can also adopt a method of inserting both the insertion slit 45 of the column element 2 and the locking tongue piece 46 of the horizontal bar element 3 in combination.

Industrial Applicability

[0032] The shield 1 for preventing droplet infection of the present invention is assumed to be applied, for example, in an emergency evacuation facility that can accept an unspecified number of evacuees during an emergency disaster. In addition, it can also be applied in other small-scale medical facilities, more specifically, in simple medical facilities without advanced isolation facilities, when it is necessary to examine patients suspected of contracting infectious diseases such as the novel coronavirus. In this case, as described above, since the shield 1 for preventing droplet infection is only a partial barrier and does not completely block the virus, it is preferable that medical staff examining the patients also wear protective clothing. In addition, the shield 1 for preventing droplet infection of the present invention can also be applied as part of infection prevention measures in cabins used by multiple passengers in compartments, such as overnight ferries. Thus, the shield 1 for preventing droplet infection of the present invention is not only used for patients who have contracted or are considered to have contracted infectious diseases such as the novel coronavirus, but also assumes the use by uninfected people as part of infection prevention measures. From such a perspective, it is also applicable to people who feel short of breath when wearing a mask while sleeping. Incidentally, if the shield sheet 5 is made of a dark-colored cloth, or a dark-colored cloth is placed on top of the transparent shield sheet 5, it can replace an eye mask and enable people to sleep soundly even in bright places.
