Description

Technical Field

[0006] , ,

[0005] , ,

[0001] The present invention relates to an elongated holding band for holding the lower body of a subject on a support base.

Background Art

[0002] When performing medical procedures in dentistry, ophthalmology, otolaryngology, etc. on infants, elderly people with dementia, or people with intellectual disabilities, etc., the patient may move unnecessarily or flap their hands and feet, and in some cases, the treatment procedure may not be properly performed.

[0003] For this reason, for example, in Patent Document 1 below, a treatment / assistance aid for coping with the above situation has been proposed. This treatment / assistance aid can stably restrain the subject on a bed or examination table with a net, and can quickly release the restraint in an emergency. <​​​​​​​​​​​​​​​​​​​​​​​​​To mitigate the above-mentioned problems and to more easily hold the subject, the inventors initially devised a method of wrapping a wide band, such as a kimono sash, around the subject to hold them on a support such as a treatment chair. However, through trial and error with the above band, it was found that if only the subject's feet or only their thighs were wrapped around the support, the part of the subject's lower body not wrapped around the band would flap around, making it impossible to adequately hold the subject's lower body.

[0007] As a result of further investigation, the inventors found that wrapping a band around the knee area, including the thighs and calves, is effective in securely holding the lower body of the subject. However, when adopting this method, they found that if the band extends to a certain width, when the band is wrapped around the support to hold the subject on the support, the band tends to interfere with various components of the support on the underside of the support (the side opposite to the surface on which the subject is placed), impairing workability.

[0008] This invention was devised in view of the above-described circumstances, and its main objective is to provide a holding band and a method of using the same that offers excellent workability and can securely hold the lower body of the subject to a support base. [Means for solving the problem]

[0009] A first aspect of the present invention is a long retaining band for holding the lower body of a person to a support base by wrapping around it, comprising a first portion extending in the longitudinal direction of the band from one end edge in the longitudinal direction of the band, a second portion extending in the longitudinal direction of the band from the other end edge in the longitudinal direction of the band, and an intermediate portion between the first portion and the second portion, wherein the first portion and the second portion each include a joining portion that allows their outer surfaces to be repeatedly joined and separated from each other, and the width of the intermediate portion is smaller than the width of the first portion and the width of the second portion.

[0010] In the retaining band of the present invention, the joining portion includes a rectangular hook-and-loop fastener whose longitudinal direction is the same as the longitudinal direction of the band, and it is preferable that two to three of the hook-and-loop fasteners are arranged side by side on the outer surface of the first portion and the outer surface of the second portion, respectively, in a direction perpendicular to the longitudinal direction of the band.

[0011] In the retaining band of the present invention, it is desirable that the edge of the hook-and-loop fastener body is spaced 10 to 30 mm away from the outer edge of the retaining band.

[0012] In the retaining band of the present invention, it is preferable that the outer layer is made of a water-repellent fabric material.

[0013] In the retaining band of the present invention, it is preferable to include two outer layers and a cushion layer disposed between the two outer layers and being more flexible than the outer layers.

[0014] In the retaining band of the present invention, it is desirable that the total length be 1500 to 2500 mm.

[0015] In the retaining band of the present invention, the width of the first portion and the width of the second portion are preferably 300 to 500 mm, and the width of the intermediate portion is preferably 100 to 250 mm.

[0016] A second aspect of the present invention is a method of using the above-described retaining band, characterized in that the retaining band is wrapped around the support base and the area around the knee, including the thigh and calf of the subject. [Effects of the Invention]

[0017] The retaining band and method of use of the present invention, by adopting the above-mentioned features, offer excellent workability and can securely hold the lower body of the subject to the support base. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0019] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The drawings contain the features of the present invention, but may include exaggerations or representations that differ from the actual structural dimensional ratios in order to aid in understanding the invention. Furthermore, the same or common elements are denoted by the same reference numerals throughout each embodiment, and redundant explanations are omitted. In addition, well-known configurations may be appropriately adopted for configurations not described herein.

[0020] Figure 1(a) is an overall plan view showing one outer surface of the retaining band 1 of this embodiment. Figure 1(b) is an overall plan view showing the other outer surface of the retaining band 1 of this embodiment. In this specification, the outer surface shown in Figure 1(a) may be referred to as the front surface, and the outer surface shown in Figure 1(b) may be referred to as the back surface. However, the retaining band 1 of the present invention can be used without distinguishing between the front surface and the back surface.

[0021] Figure 2 is a perspective view showing the use of the retention band 1 of the present invention. As shown in Figure 2, the retention band 1 of the present invention is a long band that holds the lower body of a subject 3 to a support base 4 by wrapping around it. Here, the support base 4 includes, for example, a treatment chair or a bed, and in Figure 2, a treatment chair used in dental treatment is shown. The subject 3 is, for example, a person who cannot easily accept instructions to stay still from a doctor or attendant, and examples include infants, elderly people with dementia, or people with intellectual disabilities.

[0022] The holding band 1 of the present invention wraps around both the support base 4 and the lower body of the subject 3 to hold the lower body of the subject 3. However, wrapping is not limited to wrapping the holding band 1 around multiple times. In this embodiment, the holding band 1 holds the subject 3 to the support base 4 by wrapping it around only once. Figure 3 is a side view showing the situation in which the holding band 1 is used when the subject 3 is lying down with their knees extended. Note that the therapeutic light L in Figure 2 is omitted in Figure 3. As shown in Figure 3, the holding band 1 of the present invention can hold the lower body of the subject 3 not only when the subject 3's knees are bent (for example, when the subject 3 is sitting), but also when the subject 3's knees are extended (for example, when the subject 3 is lying down).

[0023] The inventors initially devised a method of securing the subject 3 to the support stand 4 by wrapping a wide band (extending at a constant width), similar to a kimono sash, around it. However, after various trials and errors, it was discovered that if only the subject's feet or only their thighs were wrapped around the support stand with the band, the part of the subject's lower body not wrapped with the band would flap around, making it impossible to adequately secure the subject's lower body.

[0024] As a result of further investigation, the inventors found that in order to securely hold the lower body of subject 3, it is effective to wrap the band around both the support base 4 and the area around the knees, including the thighs and calves of subject 3. On the other hand, when adopting this method, it was found that if the band extends to a certain width, when the band is wrapped around to hold the lower body of subject 3 to the support base 4, the band tends to interfere with various components of the support base 4 on the back side (the side opposite to the surface on which the subject is placed), impairing workability.

[0025] In contrast, the retaining band 1 of this embodiment has the following features. As shown in Figures 1(a) and 1(b), the retaining band 1 of this embodiment includes a first portion 6, a second portion 7, and an intermediate portion 8. The first portion 6 extends in the longitudinal direction of the band from one end edge 1a in the longitudinal direction of the band. The second portion 7 extends in the longitudinal direction of the band from the other end edge 1b in the longitudinal direction of the band. The ends 1a and 1b of this embodiment each extend linearly parallel to the band width direction which is perpendicular to the band longitudinal direction. The intermediate portion 8 is provided between the first portion 6 and the second portion 7. In some of the figures in this specification, the band longitudinal direction is indicated by arrow A1, and the band width direction is indicated by arrow A2.

[0026] The first part 6 and the second part 7 each include a joint 10 that allows their outer surfaces to be repeatedly joined and separated from each other. In this embodiment, hook-and-loop fasteners are used as the joint 10, and details will be described later. In addition, in the present invention, the width W3 of the intermediate part 8 is smaller than the width W1 of the first part 6 and the width W2 of the second part. Note that these widths W1, W2, and W3 refer to widths measured parallel to the band width direction. Furthermore, if these widths W1, W2, and W3 change in the longitudinal direction of the band, the above feature means that the average of the width W3 is smaller than the average of the width W1 and the average of the width W2.

[0027] In this embodiment, the retaining band 1 is used by positioning, for example, the first portion 6 around the knee of the subject, the intermediate portion 8 on the back side of the support base 4 (shown in Figure 2), and the second portion 7 overlapping the first portion 6. At this time, the first portion 6 and the second portion 7 are joined by the aforementioned joint 10. Here, since the width W3 of the intermediate portion 8 is small as described above, the intermediate portion 8 does not interfere with various members on the back side of the support base 4, and the retaining band 1 can be easily wrapped around it. For these reasons, the retaining band 1 of the present invention offers excellent workability and can securely hold the lower body of the subject to the support base.

[0028] The configuration of this embodiment will be described in more detail below. Note that each configuration described below represents a specific aspect of this embodiment. Therefore, it goes without saying that the present invention can achieve the above-described effects even without the configurations described below. Furthermore, even if any one of the configurations described below is applied individually to the retaining band 1 of the present invention having the above-described features, an improvement in performance corresponding to each configuration can be expected. Moreover, if several of the configurations described below are applied in combination, a combined improvement in performance corresponding to each configuration can be expected.

[0029] As shown in Figure 1, the total length L1 of the retaining band 1 in this embodiment is, for example, 1500 to 2500 mm, preferably 1800 to 2200 mm. This allows it to accommodate subjects 3 (shown in Figure 2) of various body types. However, the retaining band 1 of the present invention is not limited to the above-mentioned dimensional range, and various dimensions may be adopted depending on the body type of the subject 3 and the size of the support base 4 used.

[0030] Although not shown in the figures, the intermediate portion 8 may include a length adjustment mechanism so that the total length L1 can be adjusted as appropriate. An example of such a length adjustment mechanism is one in which the intermediate portion 8 is composed of two band members that can be repeatedly joined and separated with hook-and-loop fasteners. In this embodiment, the total length L1 of the retaining band 1 can be adjusted to a desired length by appropriately adjusting the overlapping length of the two band members.

[0031] Figure 4 is an enlarged view of the first section 6 shown in Figure 1(a). As shown in Figure 4, the length L2 of the first section 6 in the band longitudinal direction is, for example, 600 to 750 mm. The width W1 of the first section 6 is, for example, 300 to 500 mm. The first section 6 also includes a fixed-width section 13 and a width-reducing section 14. The fixed-width section 13 extends from the end edge 1a of the retaining band 1 in the band longitudinal direction with a constant width W4, and in this embodiment is rectangular in shape. The width-reducing section 14 is connected to the fixed-width section 13, and the width in the band width direction decreases towards the intermediate section 8.

[0032] When the retaining band 1 is in use, the fixed-width portion 13 is located in front of the subject 3. From the viewpoint of securely holding the subject 3 with the fixed-width portion 13, the fixed-width portion 13 requires a certain area. On the other hand, if this area is excessively large, the subject 3 may feel strongly restrained or anxious. For this reason, the width W4 of the fixed-width portion 13 is, for example, 300 to 500 mm, preferably 350 to 450 mm. Similarly, the length L3 of the fixed-width portion 13 in the longitudinal direction of the band is, for example, 350 to 550 mm, preferably 400 to 500 mm.

[0033] In this specification, if the numerical ranges of the various parameters described vary depending on the measurement location, unless otherwise specified, the numerical range refers to the average of the said parameters. Furthermore, the said average refers to the sum of the parameters obtained for each of the micro-regions obtained by dividing the object to be measured into a number of appropriately sized micro-regions and measuring the corresponding parameters for each micro-region, and then dividing the sum of the parameters for each micro-region by the number of micro-regions.

[0034] From the viewpoint of ensuring the width W4 of the fixed-width section 13 while sufficiently reducing the width W3 of the intermediate section 8, the angle θ1 of the edge 14a of the width reduction section 14 (the angle with respect to the band width direction) is, for example, 40 to 60°.

[0035] As shown in Figure 1, the second part 7 has substantially the same shape as the first part 6. Therefore, the features of the first part 6 described above can also be applied to the second part 7.

[0036] As shown in Figures 1 and 4, the joint 10 of this embodiment employs, for example, a hook-and-loop fastener. The hook-and-loop fastener has multiple fine resin hooks on one side and multiple fine fabric loops on the other side, allowing these sides to be repeatedly joined and separated. The hook-and-loop fastener described herein can be fitted with well-known features, which are omitted from this specification.

[0037] The joint portion 10 of this embodiment includes a rectangular hook-and-loop fastener 11. In this embodiment, multiple hook-and-loop fasteners 11 are provided on the surface of the first portion 6, and correspondingly, multiple hook-and-loop fasteners 11 are provided on the back surface of the second portion 7. As a result, as shown in Figure 2, when the holding band 1 is wrapped around the subject 3 and the support base 4, the hook-and-loop fasteners 11 of the first portion 6 and the hook-and-loop fasteners 11 of the second portion 7 come into contact, ensuring that the lower body of the subject 3 is securely held to the support base 4. As another embodiment of the joint portion 10, for example, magnets may be used (not shown).

[0038] As shown in Figure 4, the hook-and-loop fastener body 11 has its longitudinal direction the same as the longitudinal direction of the band. In addition, two to three hook-and-loop fastener bodies 11 are arranged side by side on the outer surface of the first part 6 in a direction perpendicular to the longitudinal direction of the band. This ensures that the first part 6 and the second part 7 are securely joined together.

[0039] In the embodiment shown in Figure 4, one hook-and-loop fastener 11 is provided on the center position 1C (indicated by a dashed line) in the band width direction of the retaining band 1, and two hook-and-loop fasteners 11 are provided so as to sandwich it. With these three hook-and-loop fasteners 11, the knee of the subject 3 can be securely held.

[0040] In this embodiment, each hook-and-loop fastener 11 is positioned across the fixed-width portion 13 and the width-reducing portion 14 of the first portion 6. Furthermore, the total surface area of ​​the outer surfaces of the multiple hook-and-loop fasteners 11 provided on the first portion 6 is, for example, 50% or more, preferably 70% or more, of the surface area of ​​the outer surface of the first portion 6. This allows for a more secure bond between the first portion 6 and the second portion 7.

[0041] If the outer edge 1d of the retaining band 1 and the end edge 11e of the hook-and-loop fastener body 11 are too close together, it may become difficult to separate the first part 6 and the second part 7 when the retaining band 1 is no longer in use. For this reason, it is desirable that the end edge 11e of the hook-and-loop fastener body 11 be spaced, for example, 10 to 30 mm away from the outer edge 1d of the retaining band 1.

[0042] Figures 5(a) and 5(b) are enlarged views of the end of the first portion 6 in other embodiments. In these embodiments, the distance from the edge 1a of the retaining band 1 to the edge 11a of the hook-and-loop fastener body 11 is greater for one of the hook-and-loop fastener bodies 11 than for the other two. Also, in the embodiment shown in Figure 5(a), the edge 11a of the hook-and-loop fastener body 11 is inclined outward in the band width direction, away from the edge 1a of the retaining band 1. In the embodiment shown in Figure 5(b), the edge 11a of the hook-and-loop fastener body 11 is parallel to the edge 1a of the retaining band 1. In these embodiments, after use, the portion with the greater distance can be grasped to easily separate the first portion 6 and the second portion 7.

[0043] Figures 6(a) and 6(b) are enlarged views of the end of the first section 6 in yet another embodiment. In these embodiments, a lip portion 17 is provided that protrudes from the end of the first section 6 in the longitudinal direction of the band in order to further improve the workability when separating the first section 6 and the second section 7. The worker can easily separate the first section 6 and the second section 7 by grasping this lip portion 17. As shown in Figure 6(a), the lip portion 17 is, for example, rectangular in shape with its longitudinal direction in the band width direction. Alternatively, as shown in Figure 6(b), the lip portion 17 may be, for example, loop-shaped with both ends connected to the end of the first section 6.

[0044] The features of the hook-and-loop fastener body 11 and lip portion 17 described above in the first part 6 can also be applied to the second part 7 (shown in Figure 1).

[0045] As shown in Figure 1, the intermediate section 8 extends in the longitudinal direction of the band with a constant width W3, for example. The length L4 of the intermediate section 8 in the longitudinal direction of the band is, for example, 600 to 750 mm. The width W3 of the intermediate section 8 is, for example, 30% to 50% of the width W1 of the first section 6 (shown in Figure 3), and is preferably 100 to 250 mm. Such an intermediate section 8 has sufficient strength and can effectively avoid interference with various members on the back side of the support base 4.

[0046] Figure 7 shows a cross-sectional view of the retaining band 1 of this embodiment. As shown in Figure 7, the thickness t1 of the retaining band 1 is, for example, 5 mm or less, preferably 1 to 3 mm. The retaining band 1 includes two outer layers 21 that constitute the front and back surfaces, and a cushion layer 22 disposed between these two outer layers 21. The outer layers 21 are preferably made of a water-repellent fabric material. Here, a water-repellent fabric material refers to one that is grade 3 or higher in the "7.2 Water repellency test (spray test)" of the "Test method for waterproofness of textile products" specified in JIS L 1092 (2009). Such an outer layer 21 can prevent water from penetrating the cushion layer 22 even if water is spilled, for example, during dental treatment.

[0047] The cushion layer 22 is more flexible than the outer layer 21. This characteristic means that the density and / or bending stiffness of the cushion layer 22 are lower than that of the outer layer 21. In this embodiment, the cushion layer 22 is made of cotton, but it may be made of other materials such as foamed urethane. By including the cushion layer 22 in the retaining band 1, the feeling of pressure and anxiety experienced by the person 3 during use can be reduced.

[0048] In this embodiment, it is desirable that the two outer layers 21 and the cushion layer 22 are sewn together so that the cushion layer 22 does not shift inside. More specifically, it is desirable that the two outer layers 21 and the cushion layer 22 are sewn together along the entire outer edge 1d of the retaining band 1, as shown schematically by the dashed sewing line 23a in Figure 4. In addition, it is desirable that the hook-and-loop fastener body 11 is also sewn to the two outer layers 21 and the cushion layer 22 (see sewing line 23b). In this case, it is desirable that at least two long sides extending in the longitudinal direction of the hook-and-loop fastener body 11 are sewn together. In a more desirable embodiment, the hook-and-loop fastener body 11 is sewn along the entire outer edge. This reliably prevents the cushion layer 22 from shifting inside and also suppresses peeling of the hook-and-loop fastener body 11. Note that the sewing lines 23a and 23b shown in Figure 4 are omitted in other figures.

[0049] Figure 8 shows an overall plan view of the retaining band 1 in another embodiment. As shown in Figure 8, in this embodiment, two hook-and-loop fasteners 11 are arranged in each of the first part 6 and the second part 7 so as to sandwich the center position 1C (shown by a dashed line) in the band width direction of the retaining band 1. This allows both the thigh and calf of the subject 3 to be held, and the first part 6 and the second part 7 can be easily separated when the retaining band 1 is no longer in use. In this case, from the viewpoint of suppressing the shifting of the cushion layer 22, it is desirable that a sewing line for sewing the two outer layers 21 and the cushion layer 22 extends over the center position 1C (not shown).

[0050] Figure 9 shows an overall plan view of the retaining band 1 according to another embodiment of the present invention. As shown in Figure 6, in this embodiment, the intermediate portion 8 is offset to one side in the band width direction. As a result, the first transverse edge 26 extending in the longitudinal direction of the band on one side in the band width direction of the retaining band 1 is straight, while the second transverse edge 27 extending in the longitudinal direction of the band on the other side in the band width direction is curved to reduce the width of the retaining band 1. Such a retaining band 1 makes it easier to avoid interference between the intermediate portion 8 and various members on the back side of the support base 4, depending on the type of support base 4.

[0051] As shown in Figures 2 and 3, a chest support band 5 may be used in conjunction with the support band 1 of the present invention to more securely hold the subject 3. The chest support band 5 is a long band that, by wrapping around it, holds the upper body, particularly the chest, of the subject 3 to the support base 4. Figure 10(a) is an overall plan view showing one outer surface (front) of the chest support band 5, and (b) is an overall plan view showing the other outer surface (back) of the chest support band 5. As shown in Figures 10(a) and (b), the chest support band 5 has a first part 6, a second part 7, and an intermediate part 8 that extend with a constant width W5. The total length L5 of the chest support band 5 is, for example, 1500 to 2500 mm. The width W5 of the chest support band 5 is, for example, 200 to 300 mm. Except for the above features, the chest support band 5 may adopt the features of each part described in the embodiments shown in Figure 1, etc.

[0052] Figure 11(a) is an overall plan view showing one outer surface of the fixed-width retaining band 2, which is an invention related to the present invention, and (b) is an overall plan view showing the other outer surface of the fixed-width retaining band 2. This fixed-width retaining band 2 is a long band that can securely hold the lower body of the subject 3 to the support base 4, with features that differ from the retaining band 1 of the present invention.

[0053] Specifically, the fixed-width holding band 2 has a first section 6, a second section 7, and an intermediate section 8 that extend with a constant width W6. Furthermore, the intermediate section 8 (shown with darker dots than the hook-and-loop fastener body 11 in Figure 11) is made of a material with higher elasticity than the first section 6 and the second section 7. This feature means that when a tensile test (for example, a tensile test conforming to JIS L 1096) is performed under the same conditions, the elongation rate of the intermediate section 8 is greater than that of the first section 6 and the second section 7. The material of this intermediate section 8 can be, for example, a rubber sheet. This intermediate section 8 is connected to the first section 6 and the second section 7 by rivets 28. With such a fixed-width holding band 2 having an intermediate section 8, even if various components are arranged on the back side of the support base 4, the intermediate section 8 that comes into contact with those components deforms appropriately, allowing for excellent workability and secure holding of the lower body of the subject 3 to the support base 4.

[0054] The total length L6 of the fixed-width retaining band 2 is, for example, 1500 to 2500 mm. The width W6 of the fixed-width retaining band 2 is, for example, 200 to 300 mm. In addition to the above features, the fixed-width retaining band 2 can adopt the features of each part described in the embodiment shown in Figure 1, etc.

[0055] Although particularly preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the illustrated embodiments and can be implemented in various modified forms. [Industrial applicability]
