Description

The present invention relates to a medical tray.

Medical instruments, clothing, etc. used for surgery, diagnosis, etc. are transported to the medical site in a state of being housed in a dedicated medical tray. Medical professionals such as doctors and nurses take out various items from medical trays and use them for surgery and diagnosis.

Used medical equipment, medical trays, and other medical waste are dumped in medical waste containers. Generally, the cost of disposing (disposal) a container for medical waste is determined for each container. Therefore, in order to reduce the disposal cost of medical waste, it is desirable to store as much medical waste as possible in one container for medical waste. For example, in a procedure using a medical device such as a catheter, the amount of medical waste generated by one procedure is relatively large, so that the decrease in medical economic efficiency due to the increase in the disposal cost of medical waste becomes an issue. ..

The following Patent Document 1 discloses a medical tray provided with a bottom portion and a side wall portion forming a storage space, and the bottom portion can be folded and made compact while the article is taken out from the storage space. By folding the bottom of this medical tray in half along the creases (ribs) and stacking them, the area (area) of the bottom at the time of disposal can be reduced. Therefore, the medical tray described in Patent Document 1 can be stored in a larger container for medical waste at the time of disposal. As a result, medical institutions such as hospitals can reduce the cost of disposing of medical waste.

International Publication 2011/108297

However, since the medical tray described in Patent Document 1 has a structure in which the bottoms are folded and overlapped with each other, the bottoms maintain a certain size even in the folded state. Therefore, it can be said that the medical tray has room for further improvement in terms of miniaturization at the time of disposal.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a medical tray that can be made more compact at the time of disposal and can store articles to be accommodated in a stable state. ..

The medical tray according to the present invention includes a bottom portion, a side wall portion provided along the outer periphery of the bottom portion, and a reinforcing member arranged on the bottom portion, and the reinforcing member is arranged on the bottom portion. It is more flexible than the side wall portion in the absence state, and the bottom portion can be folded so that the side wall portions facing each other across the bottom portion come into contact with each other by deforming or moving the reinforcing member . The reinforcing member has a plate-shaped member that is harder than the bottom portion and is arranged on the outer surface or the inner surface of the bottom portion, and the plate-shaped member has a crease formed by forming the reinforcing member into the reinforcing member. By folding along the plate-shaped members, the plate-shaped members can be folded so as to overlap each other.

In the medical tray described above, the bottom portion can be folded flat along the direction in which the side wall portions come into contact with each other by deforming or moving the reinforcing member in a state where the article is taken out from the bottom portion. Therefore, the medical tray can be made more compact in shape when it is disposed of. Further, the reinforcing member prevents the bottom portion from being inadvertently deformed due to the weight of the article when the article is housed in the medical tray. Therefore, the medical tray can store the article to be accommodated in a stable state, and can suitably maintain the product quality of the article.

<First Embodiment>
FIG. 1 shows a medical device set 10 and a medical tray 100 according to the present embodiment, and FIGS. 2 to 5 show a medical tray 100.

As shown in FIG. 1, the medical device set 10 includes a plurality of articles 210, 220, 230 and articles 210, 220, respectively, which are used when performing various medical practices in a medical field such as an operating room. It comprises a medical tray 100 capable of accommodating and storing 230.

The article is, for example, a gown 210, a drape 220, and a case 230 containing various medical devices (eg, syringes, needles, scalpels, etc.). The type and number of articles to be stored and stored in one medical device set 10 are not particularly limited. For example, the accommodation spaces 110 and 120 of the medical tray 100 can also accommodate a catheter, a guide wire, an introducer, and the like.

As shown in FIG. 1, the gown 210 and the drape 220 can be mounted on, for example, the side wall portions 141 and 145 of the medical tray 100. The case 230 and other medical devices can be arranged, for example, in the accommodation spaces 110 and 120. Further, when the medical device set 10 is stored or transported in an unused state, it can be packaged in a predetermined packaging bag (for example, a peel bag, a cloth bag, etc.).

Next, the medical tray 100 will be described.

2 (A) and 2 (B) show the medical tray 100 in a state where the articles 210, 220, and 230 are taken out. The medical tray 100 shown in FIGS. 2A and 2B shows a state in which the side wall portions 143, 144, 146, and 147, which will be described later, are not folded.

The medical tray 100 includes a first bottom portion 131, a plurality of side wall portions 141, 142, 143, 144 provided along the outer circumference of the first bottom portion 131, and a reinforcing member 160 arranged on the first bottom portion 131. It is equipped with.

With the first bottom portion 131 and each side wall portion 141, 142, 143, 144 (hereinafter, each side wall portion is referred to as a first side wall portion 141, a second side wall portion 142, a third side wall portion 143, and a fourth side wall portion 144). The space surrounded by the space forms a first accommodation space 110 capable of accommodating articles and the like.

Further, the medical tray 100 includes a second storage space 120 separated from the first storage space 110 by separating the first side wall portion 141. The second accommodation space 120 has a second bottom portion 132 and each side wall portion 141, 145, 146, 147 (hereinafter, each side wall portion is referred to as a fifth side wall portion 145, a sixth side wall portion 146, and a seventh side wall portion 147). It is formed in a space surrounded by. Like the first accommodation space 110, the second accommodation space 120 can accommodate articles and the like.

The first bottom portion 131 is more flexible than the side wall portions 141, 142, 143, 144 forming the first accommodation space 110 in the state where the reinforcing member 160 is not arranged. Therefore, as will be described later, when the reinforcing member 160 is removed from the first bottom portion 131, the first bottom portion 131 can be deformed so as to reduce the volume of the first accommodation space 110 (FIGS. 3 and 4). reference). More specifically, in the first bottom portion 131, by moving the reinforcing member 160 to the outside of the first accommodation space 110, a pair of side wall portions 141 and 142 facing each other across the first bottom portion 131 are formed. It can be folded so that it touches each other.

As described above, the side wall portions 141, 142, 143, 144 of the medical tray 100 are less likely to be deformed (harder) than the first bottom portion 131 in the state where the reinforcing member 160 is moved. Therefore, for example, in the medical tray 100, when the articles 210, 220, etc. are placed on the side wall portions 141, 142, 143, 144, the weights of the articles 210, 220, etc. are applied to the side wall portions 141, 142, 143, respectively. It is possible to prevent the 144 from being deformed so as to be crushed.

The magnitude relationship of flexibility in the present specification can be compared, for example, based on Vickers hardness (JIS R1610: 2003) in the comparison of different resin materials, and Vickers hardness (JIS Z2244: 2009) in the comparison of different metal materials. Alternatively, it can be specified based on JIS Z2251: 2009). Further, the magnitude relationship of the flexibility between the resin material and the metal material can be defined, for example, by measuring and comparing both of them with reference to one of the above. The magnitude relationship of flexibility can be defined based on the thickness of each member, for example, in the comparison of the same resin materials.

As shown in FIG. 2B, the first bottom portion 131 has a substantially rectangular shape (rectangular shape) in a plan view. The first side wall portion 141 and the second side wall portion 142 are arranged along the long side of the first bottom portion 131. Further, the third side wall portion 143 and the fourth side wall portion 144 are arranged along the short side of the first bottom portion 131.

A set of side wall portions 141 and 142 facing each other with the first bottom portion 131 sandwiched between them has substantially the same planar shape. Each side wall portion 141, 142 has a substantially rectangular shape in a front view of each side wall portion 141, 142 (for example, a front view from the inside of the first accommodation space 110). Further, as shown in FIG. 2B, the side wall portions 141 and 142 are erected so as to form a substantially straight line in a plan view in a state where no external force is applied in the direction of folding the first bottom portion 131. ing.

A set of side wall portions 143 and 144 facing each other with the first bottom portion 131 interposed therebetween have substantially the same planar shape. Each side wall portion 143, 144 has a substantially rectangular shape in the front view of each side wall portion 143, 144. Further, as shown in FIG. 2B, the side wall portions 143 and 144 are erected so as to form a substantially straight line in a plan view in a state where no external force is applied in the direction of folding the first bottom portion 131. ing.

The first bottom portion 131 has a rectangular shape (rectangular shape) in a plan view. However, the shape of the first bottom 131 is not particularly limited as long as the accommodation space 110 can be formed. For example, the first bottom portion 131 may have a shape such as a circle, an ellipse, a rhombus, or a trapezoid in a state before being folded. The first bottom portion 131 is formed in a circular shape, an elliptical shape, or the like, and the first side wall portion 141 and the second side wall portion 142 cannot be defined by one side arranged with a vertex sandwiched between them. In this case, each of the side wall portions 141 and 142 can be defined, for example, in an arbitrary region (range) of the side wall portions facing each other with the first bottom portion 131 interposed therebetween.

As shown in FIGS. 2A and 3A, the third side wall portion 143 has a predetermined crease 143a. The crease 143a forms a folding starting point of the third side wall portion 143 when the first side wall portion 131 is brought close to the first side wall portion 141 so as to be in contact with the first side wall portion 131 and the first bottom portion 131 is folded (FIG. 3 (A) and FIG. See FIG. 3 (B)). When the user of the medical tray 100 (for example, a doctor, a nurse, etc.) folds the first bottom portion 131, the first bottom portion of the medical tray 100 is folded by folding the third side wall portion 143 starting from the fold 143a. The 131 can be folded smoothly.

The crease 143a can be formed, for example, at a portion where the wall thickness of a part of the third side wall portion 143 is made smaller than the wall thickness of the other portion of the third side wall portion 143 to facilitate the formation of a bending starting point. Further, the crease 143a may be formed as long as it is possible to form a folding starting point of the third side wall portion 143. For example, the crease 143a is formed by a rib-shaped line protruding from the third side wall portion 143 side to the first accommodation space 110 side. You may.

The fourth side wall portion 144 has a crease 144a forming a starting point of folding, similarly to the third side wall portion 143.

The folds 143a and 144a formed in the side wall portions 143 and 144 have positions, shapes, and numbers as long as they can form a folding starting point in each side wall portion 143 and 144 when the first bottom portion 131 is folded. The specific structure and the like are not particularly limited. However, each crease 143a, 144a has a height substantially the same as the height of each side wall portion 143, 144, for example, in order to enable smooth bending of the first bottom portion 131, and the longitudinal length of each side wall portion 143, 144. It is preferable to form one by one at a substantially center position in the direction (extending direction).

Further, each fold 143a, 144a defines a bending direction so that each side wall portion 143, 144 is bent inward of the first accommodation space 110, for example, as shown in FIGS. 3A and 3B. Can be formed as follows. However, the folds 143a and 144a may be formed so as to define the bending direction so that the side wall portions 143 and 144 are bent to the outside of the first accommodation space 110. By forming the folds 143a and 144a so as to define the bending direction of the side wall portions 143 and 144 in this way, the medical tray 100 can be combined with the first side wall portion 141 when the first bottom portion 131 is folded. Since the second side wall portion 142 is folded so as to overlap each other, the shape in the folded state becomes more compact.

The first bottom 131 can be formed of, for example, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate or the like. Further, the side wall portions 141, 142, 143, 144 forming the first accommodation space 110 together with the first bottom portion 131 can be formed of, for example, the same material as above or a material harder than the above.

When each side wall portion 141, 142, 143, 144 is formed of the same material as the first bottom portion 131, it can be formed so as to have a larger wall thickness than, for example, the first bottom portion 131. By forming the side wall portions 141, 142, 143, 144 in this way, the side wall portions 141, 142, 143, 144 have the first bottom portion 131 in a state where the reinforcing member 160 is moved from the first bottom portion 131. It is less likely to deform (less flexible).

As shown in FIGS. 2A and 2B, the medical tray 100 seals the hole 171 formed in the first bottom 131 and the hole 171 and is removable from the first bottom 131. It has a sealing member 173 and the like.

In the medical tray 100, for example, in a medical field, in a state where an article is taken out from the first accommodation space 110 and a reinforcing member 160 is taken out, a used or unused medical device (catheter or the like) is put into a predetermined liquid (caterate or the like). For example, it can be used as a container for storing in a state of being immersed in (physiological saline). At that time, the user can, for example, store the liquid in the first storage space 110.

The seal member 173 prevents the liquid from being discharged from the hole 171 when the seal member 173 is arranged so as to cover the hole 171 of the first bottom 131. When the user discharges the liquid stored in the first storage space 110, the user removes the seal member 173 to discharge the liquid from the first storage space 110 through the hole 171 formed in the first bottom portion 131. be able to.

The shape of the hole 171 and the position and number of the holes 171 are not particularly limited as long as the folding of the first bottom 131 is not hindered. However, as shown in FIG. 2B, the hole portion 171 is preferably formed near the center position of the first bottom portion 131 in the plan view of the first bottom portion 131. The medical tray 100 has a hole 171 formed at a position as described above, so that when the liquid is discharged, a short distance is provided from the four corners of the first bottom 131 toward the center position of the first bottom 131. Since the liquid can be easily moved, the liquid can be discharged more smoothly.

As shown in FIG. 5, the seal member 173 can be formed of, for example, a film-like member that covers the hole 171 from the inner surface 131a side of the first bottom portion 131. The material of the sealing member 173 is not particularly limited, but can be formed from, for example, a known resin film. Further, the seal member 173 can be removably fixed to the first bottom portion 131 by a known method such as an adhesive, an adhesive, or fusion. The seal member 173 is not limited to the film-shaped member, and may be formed of, for example, a plug-shaped member that can be attached to and detached from the hole 171.

As shown in FIGS. 2A, 2B, and 5, the reinforcing member 160 is composed of a plate-shaped member arranged on the inner surface 131a of the first bottom portion 131.

The reinforcing member 160 can be made of a member that is harder than the first bottom portion 131. The hard member means, for example, that the material of the reinforcing member 160 itself is made of a material harder than that of the first bottom portion 131, and that the reinforcing member 160 is made of a material of the same quality as that of the first bottom portion 131. It is included that the reinforcing member 160 has a harder physical property than the first bottom 131 due to the large thickness of the reinforcing member 160 or the inclusion of a reinforcing body (a linear member 561 or the like described later) in the reinforcing member 160. Is done.

As shown in FIG. 2B, the reinforcing member 160 is composed of a plate-shaped member having a substantially rectangular shape (rectangular shape), which is one size smaller than the first bottom portion 131 when viewed in a plan view. When the medical tray 100 is folded, the user or the like moves the reinforcing member 160 from the first bottom 131 by grasping the reinforcing member 160 with his / her fingers or the like, and moves the reinforcing member 160 from the first accommodation space 110. Can be taken out.

Further, in the present embodiment, since the shape of the first bottom portion 131 in a plan view is a substantially rectangular shape, the reinforcing member 160 also has a substantially rectangular shape in a plan view. However, the reinforcing member 160 does not have to be formed in a shape similar to that of the first bottom portion 131. In the reinforcing member 160, for example, in a state where the article 230 or the like is housed in the first bottom portion 131 (see FIG. 1), the first bottom portion 131 is inadvertently deformed (deformation such as bending of the first bottom portion 131). It may be formed so as to cover a certain range (area) of the first bottom portion 131 so as to be able to suppress the above. For example, when the first bottom portion 131 is formed in a rectangular shape, the reinforcing member 160 may have a circular or elliptical shape arranged so as to cover a certain range of the first bottom portion 131. Further, for example, when the first bottom portion 131 is formed in a circular shape, the reinforcing member 160 may have a rectangular shape or the like arranged so as to cover a certain range of the first bottom portion 131.

The plate-shaped member constituting the reinforcing member 160 may be formed with a crease 461a that enables the reinforcing member 160 itself to be overlapped and folded, as in the case of the reinforcing member 460 described later (FIG. 10B). ) And FIG. 10 (C).

Regarding the magnitude relationship of the flexibility of the first bottom portion 131, the side wall portions 141, 142, 143, 144, and the reinforcing member 160, the first bottom portion 131 is more flexible than the side wall portions 141, 142, 143, 144, and the first bottom portion 131 is more flexible. As long as the first bottom portion 131 is more flexible than the reinforcing member 160, the present invention is not particularly limited. That is, there is no particular limitation on the magnitude relationship of the flexibility between the reinforcing member 160 and the side wall portions 141, 142, 143, 144.

The reinforcing member (plate-shaped member) 160 can be formed of, for example, acrylic resin, ABS resin, polyethylene, polypropylene, polystyrene, polyethylene terephthalate, or the like. The thickness of the reinforcing member 160 is not particularly limited, but can be formed, for example, from 0.6 mm to 3.0 mm.

The medical tray 100 may have, for example, a temporary fixing portion for temporarily fixing the reinforcing member 160 in a state where the reinforcing member 160 is arranged on the first bottom portion 131. By having the temporary fixing portion, the medical tray 100 can prevent the reinforcing member 160 from being inadvertently misaligned. The temporary fixing portion can be formed, for example, with an adhesive tape or the like for fixing the reinforcing member 160 to the first bottom portion 131 or each side wall portion 141, 142, 143, 144 or the like.

As described above, the medical tray 100 according to the present embodiment is configured to form a second storage space 120 partitioned from the first storage space 110 by the first side wall portion 141 (FIG. 2 (A). ). The second accommodation space 120 is formed by a second bottom portion 132 and a plurality of side wall portions 141, 145, 146, and 147.

The second bottom portion 132 can be configured to have substantially the same structure (shape, material, flexibility) as the first bottom portion 131. Further, the fifth side wall portion 145 can be configured to have substantially the same structure as the second side wall portion 142. Further, the sixth side wall portion 146 can be configured to have substantially the same structure as the third side wall portion 143. Further, the seventh side wall portion 147 can be configured to have substantially the same structure as the fourth side wall portion 144. Therefore, in the present embodiment, the description of each portion (bottom portion and side wall portion) forming the second accommodation space 120 will be omitted.

In the medical tray 100, for example, the reinforcing member 160 can be arranged on the second bottom 132 in the same manner as the first bottom 131. Further, in the medical tray 100, for example, the hole portion 171 and the sealing member 173 can be arranged in the second bottom portion 132.

When the bottom 131, 132 and the side wall 141, 142, 143, 144, 145, 146, 147 constituting the medical tray 100 are formed of, for example, a resin material, they are integrally formed by a known resin molding method. Can be formed. Further, each bottom 131, 132 and each side wall 141, 142, 143, 144, 145, 146, 147 constituting the medical tray 100 are transparent so that the inside of the medical tray 100 can be visually recognized from the outside, for example. Or translucent.

Next, an example of using the medical tray 100 will be described with reference to FIGS. 2 to 4.

As shown in FIG. 1, the medical tray 100 can be prepared in a state in which the articles 210, 220, and 230 are stored and housed, that is, in a state in which the medical device set 10 is configured, when performing a predetermined procedure or the like. .. When transporting the medical device set 10, a reinforcing member 160 is arranged on the first bottom 131 of the medical tray 100. Therefore, the medical tray 100 can prevent the first bottom portion 131 from bending and deforming due to the weight of the article 230 housed in the first storage space 110.

As shown in FIGS. 2A and 2B, the user takes out the articles 210, 220, 230 stored and contained in the medical tray 100 when performing the procedure. After taking out the articles 210, 220, and 230 from the medical tray 100, the user moves the reinforcing member 160 from the first bottom 131 and takes out the reinforcing member 160 to the outside of the first storage space 110 before the procedure.

The user supplies a liquid such as physiological saline to the first storage space 110 of the medical tray 100 in a state where the articles 210, 220, and 230 are taken out from the medical tray 100. The user can store the medical device such as a catheter immersed in the liquid contained in the first storage space 110 according to the progress of the procedure. The user removes the seal member 173 arranged on the first bottom 131 of the medical tray 100 when the liquid contained in the first storage space 110 is discharged. The liquid contained in the first storage space 110 is discharged from the first storage space 110 through the hole 171.

When the user disposes of the medical tray 100, as shown in FIGS. 3 (A) and 3 (B), the user faces the first side wall portion 141 and the second side wall portion with the first bottom portion 131 sandwiched between them. Fold it so that 142 is in contact with it. For example, the user presses the outer surface of the second side wall portion 142 toward the first side wall portion 141 to bring the second side wall portion 142 closer to the first side wall portion 141. At this time, the crease 143a formed in the third side wall portion 143 forms a bending starting point in the third side wall portion 143, and the crease 144a formed in the fourth side wall portion 144 is bent in the fourth side wall portion 144. Form a starting point.

When folding the first bottom wall 131, the user may, for example, press the outer surface of the first side wall portion 141 so as to bring the first side wall portion 141 closer to the second side wall portion 142, or the first side wall portion 141. Both the portion 141 and the second side wall portion 142 may be pressed at the same time so that the side wall portions 141 and 142 are relatively close to each other.

As shown in FIGS. 4A and 4B, the user can fold the first bottom portion 131 by sufficiently bringing the first side wall portion 141 and the second side wall portion 142 close to each other. The first side wall portion 141 and the second side wall portion 142 are arranged so as to be overlapped with each other so as to form a predetermined folded portion 150.

As shown in FIGS. 4 (A) and 4 (B), the first storage space 110 of the medical tray 100 disappears from the medical tray 100 (accommodating articles) when the first bottom 131 is folded. Transforms into a state where there is not enough volume for it). Therefore, the medical tray 100 is miniaturized and becomes more compact than before the first bottom 131 is folded.

The medical tray 100 has, for example, a second side wall portion 142 with respect to the first side wall portion 141 in order to maintain a folded state of the first bottom portion 131 (maintaining a state in which the folded portion 150 is formed). It may be configured to have a fixing portion for fixing the. The fixing portion includes, for example, a clip made of a member different from the medical tray 100, and a fitting portion integrally formed with the medical tray 100 (for example, each side wall portion mechanically formed by a concave-convex fitting type). (A thing that fixes 141 and 142), an adhesive, a tape having adhesiveness, and the like can be used.

Further, the user can eliminate the second storage space 120 from the medical tray 100 by folding the second bottom portion 132 in the same manner as the first bottom portion 131, if necessary.

Further, when the medical tray 400 is formed so as to have two accommodation spaces 110 and 120, the reinforcing member 460 may be arranged at the bottom portions 131 and 132, or may be arranged only at the second bottom portion 132. May be good.

<Third Embodiment>
Next, the medical tray 500 according to the third embodiment of the present invention will be described. The configurations and members not particularly mentioned in the third embodiment, the procedure for using the medical tray 500, and the like can be the same as those in each of the above-described embodiments, and the description thereof will be omitted as appropriate.

The medical tray 100 according to the first embodiment is composed of a plate-shaped member in which the reinforcing member 160 is arranged on the inner surface 131a of the first bottom 131 (see FIG. 5), and is for medical use according to the second embodiment. The tray 400 was composed of a plate-shaped member in which the reinforcing member 460 is arranged on the outer surface 131b of the first bottom portion 131 (see FIG. 9). On the other hand, in the medical tray 500 according to the third embodiment, as shown in FIGS. 11 and 12, the reinforcing member 560 has a plurality of linear members 561 and a gap portion 563 surrounded by the plurality of linear members 561. It is composed of.

As shown in FIG. 12, the first bottom portion 531 of the medical tray 500 has a space portion 533 in which the linear member 561 is arranged. Further, the first bottom portion 531 has a first bottom member 531a and a second bottom member 531b which are arranged so as to form a space portion 533 so as to be overlapped with each other in the thickness direction of the first bottom portion 531.

The reinforcing member 560 is arranged on the outer surface side of the first bottom portion 531. The outer surface side of the first bottom portion 531 means the surface side opposite to the surface facing the first accommodation space 110 (inner surface of the first bottom member 531a) (see FIG. 12). For example, when the first bottom portion 531 is composed of a plurality of bottom members 531a and 513b stacked in layers as in the present embodiment, reinforcements arranged in the space portion 533 formed between the respective members 531a and 531b. The member 560 can be included in the member arranged on the outer surface side of the first bottom portion 531.

As shown in FIG. 12, the first bottom member 531a and the second bottom member 531b are predetermined in advance so that the first bottom portion 531 can be smoothly deformed, for example, following the deformation of the linear member 561 described later. Forming deflection. The specific shape and the like of the deflection of each bottom member 531a and 531b are not particularly limited as long as the deformation of the first bottom portion 331 can be tolerated. Further, the thickness of the space portion 533 (dimension in the vertical direction in FIG. 12) formed between the first bottom member 531a and the second bottom member 531b is not particularly limited as long as the linear member 561 can be arranged.

The first bottom member 531a and the second bottom member 531b can be formed of, for example, the same material as the first bottom portion 131 (see FIG. 5) described above.

The linear member 561 can be fixed to, for example, the first bottom portion 531. When the first bottom portion 531 is composed of two bottom members 531a and 531b arranged in layers as in the present embodiment, for example, the linear member 561 is the outer surface of the first bottom member 531a and the outer surface of the first bottom member 531a. It can be fixed to at least one of the inner surfaces of the second bottom member 531b. Further, if the entire circumference of the linear member 561 in the circumferential direction in the cross section shown in FIG. 12 is fixed to each of the bottom members 531a and 531b, the linear member 561 may hinder the smooth deformation of the linear member 561 described later. .. Therefore, the linear member 561 is, for example, only a part of the linear member 561 facing the outer surface of the first bottom member 531a and / or only a part of the linear member 561 facing the inner surface of the second bottom member 531b. Can be fixed.

Further, when the first bottom portion 531 is composed of one member (see FIG. 5 and the like), the linear member 561 can be arranged along the outer surface of the first bottom portion 531. In this case, the linear member 561 can be fixed to the outer surface of the first bottom portion 531, for example.

With reference to FIG. 11, the end portion 561a (each end portion 561a of the plurality of linear members 561) arranged on the first side wall portion 141 side of the linear member 561 is, for example, with respect to the first side wall portion 141. Can be fixed. On the other hand, the end portion (each end portion of each of the plurality of linear member 561; not shown) arranged on the second side wall portion 142 side of the linear member 561 is not fixed to the second side wall portion 142, for example. Can be arranged like this. By arranging each linear member 561 in this way, as shown in FIG. 13, when the second side wall portion 142 is deformed so as to be in contact with the first side wall portion 141, the linear member 561 has a second side wall portion. The end portion 561b side that is not fixed to the portion 142 is deformed so as to be expanded in a direction intersecting the folding direction of the first bottom portion 131 (direction of arrow a in the figure). As a result, in the linear member 561, the end portion 561a side fixed to the first side wall portion 141 is supported by the first side wall portion 141, and the gap portion 563 intersects the folding direction of the first bottom portion 531 (in the figure). It is deformed so as to spread easily and smoothly in the direction of the arrow a).

The linear member 561 can be formed of, for example, a wire having a circular cross-sectional shape. Further, the linear member 561 can be formed of a material harder than the first bottom portion 531. As such a material, the linear member 561 can be formed of, for example, SUS, Ni—Ti or the like. The cross-sectional shape, outer diameter (when the linear member 561 has a circular cross section), the number of linear members 561 and the like are not particularly limited.

As shown in FIG. 11, the gap portion 563 of the reinforcing member 560 has a rhombic shape due to the linear members 561 arranged non-parallel in the state before the third side wall portion 143 and the fourth side wall portion 144 are folded. Is forming. The gap portion 563 forms a rhombus in the plan view of the first bottom portion 531.

The linear members 561 are arranged so that a plurality of linear members 561 overlap each other so as to form a predetermined pattern. As shown in FIG. 11, the plurality of linear members 561 are arranged so as to partially form a grid pattern in a plan view, for example, in a state where the first bottom portion 531 is not folded. The specific arrangement shape (pattern in a plan view) of the plurality of linear members 561 is not particularly limited.

The plurality of linear members 561 can be arranged so as to form a predetermined angle θ1 in the lattice-shaped portion, for example, in a state where the first bottom portion 531 is not folded.

As shown in FIG. 13, the reinforcing member 560 extends in a direction in which the gap portion 563 intersects the folding direction (direction of arrow a in the drawing) when the third side wall portion 143 and the fourth side wall portion 144 are folded. transform. At this time, the linear member 561 is deformed following the deformation of the first bottom portion 531. Therefore, the user presses the second side wall portion 142 so as to bring it into contact with the first side wall portion 141, so that the state shown in FIGS. 11 to 13 and the state shown in FIGS. 13 to 14 are for medical use. The tray 500 can be deformed.

In the medical tray 500, when the first bottom portion 531 is folded, the angle θ2 of the grid-like portion formed by the linear member 561 is formed before the third side wall portion 143 and the fourth side wall portion 144 are folded. It becomes larger than the angle θ1 of the shaped portion.

When the reinforcing member 560 includes the linear member 561 as in the present embodiment, when both the third side wall portion 143 and the fourth side wall portion 144 are deformed so as to be folded inside the first accommodation space 110, the wire is formed. There is a possibility that the shape members 561 may interfere with each other in the first accommodation space 110. As a result, it becomes difficult for the medical tray 500 to smoothly deform the linear member 561. Therefore, it is preferable that the third side wall portion 143 is deformed so as to project to the outside of the first accommodation space 110, for example, as shown in FIGS. 12 and 14.

Further, as shown in FIG. 11, for example, when the hole portion 171 and the seal member 173 are provided in the first bottom portion 531 of the medical tray 500, the hole portion 171 and the seal member 173 prevent the deformation of the reinforcing member 560. It is preferable to arrange the reinforcing member 560 at a position shifted by a predetermined distance so as not to be present.

Further, as shown in FIG. 11, in the medical tray 500, the reinforcing member 560 is arranged only on the first bottom portion 531. For example, the reinforcing member 560 is also arranged on the second bottom portion 132 in the same manner as the first bottom portion 531. It is also possible to arrange the reinforcing member 560 only on the second bottom portion 132.

As described above, the medical tray 500 according to the present embodiment includes the reinforcing member 560 including a plurality of linear members 561 and a gap portion 563 surrounded by the plurality of linear members 561. The reinforcing member 560 is arranged on the outer surface side of the first bottom portion 531 so that when the third side wall portion 143 and the fourth side wall portion 144 are folded, the gap portion 563 extends in a direction intersecting the folding direction. Transforms into.

In the medical tray 500 configured as described above, in the state before the third side wall portion 143 and the fourth side wall portion 144 are folded, the first bottom portion 531 is inadvertently deformed by the linear member 561 of the reinforcing member 560. It can be suitably prevented. Further, when the third side wall portion 143 and the fourth side wall portion 144 are folded, the medical tray 500 is deformed so that the gap portion 563 extends in a direction intersecting the folding direction, so that the first bottom portion 531 is deformed. The reinforcing member 560 can be smoothly deformed by following it. Therefore, the medical tray 500 can be transformed into a compact state at the time of disposal.

Further, the gap portion 563 of the reinforcing member 560 forms a rhombus shape by the linear members 561 arranged non-parallel in the state before folding the third side wall portion 143 and the fourth side wall portion 144. Therefore, when the third side wall portion 143 and the fourth side wall portion 144 are folded, the medical tray 500 is deformed so that the gap portion 563 expands together with the linear member 561. Thereby, the medical tray 500 can smoothly fold the third side wall portion 143 and the fourth side wall portion 144.

Further, the linear member 561 is fixed to the first bottom portion 531. Therefore, the linear member 561 can be easily deformed by following the deformation of the first bottom portion 531.
