Description

[Technical Field]

[0001] The present invention relates to a restraint for restraining an animal. [Background technology]

[0002] According to the 2020 Japanese census, single-person households accounted for 38% of households, making living alone the most common type of household in modern Japan. Perhaps due to the loneliness of living alone, an increasing number of households are keeping small animals (dogs, cats, rabbits, etc.) as pets indoors.

[0003] One of the disadvantages of keeping animals indoors is that they may have to be kept in cages when no one is at home. Caged animals may chew on the cage when they want food or to play outside, and chewing too hard on the hard wire mesh of the cage can cause oral problems such as crooked teeth. In rabbits in particular, this is known to cause malocclusion of the incisors. In such cases, oral treatment is required, such as filing down overgrown or deformed teeth. In such cases, it is advisable to perform the treatment under anesthesia.

[0004] Inhalation anesthesia using isoflurane or sevoflurane is a common and simple method of anesthesia for animals. However, because inhalation anesthesia requires removal of the inhalation mask, animal procedures must be performed quickly or intermittently, which is inconvenient. Furthermore, while intravenous anesthesia can be used to perform procedures on animals under continuous anesthesia, it can be problematic because it places a strain on the animal and causes stress due to drug administration, and because the anesthesia can be so deep that it takes a long time for the animal to recover.

[0005] Conventionally, when securing small animals, there are methods that involve placing the animal on a stand and clamping the head with an axis (Patent Document 1), methods that secure the head with a jaw (Patent Document 2), methods that place the animal in a case and secure only the neck (Patent Document 3, Patent Document 4), and methods that hold down the limbs (Patent Document 5). Most of the basic structures that secure only the neck are commercially available. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2003-290258 [Patent Document 2] Patent Publication No. 11-332891 [Patent Document 3] Patent Publication No. 2003-190191 [Patent Document 4] Jitsuzen Showa 63-188009 [Patent Document 5] Mito 3016519 Summary of the Invention [Problem to be solved by the invention]

[0007] Patent Document 1 is suitable for small animals, particularly mice and rats, but when it comes to animals the size of rabbits, cats, etc., it is difficult to immobilize them using only a thin shaft, which is a problem. Furthermore, Patent Documents 2 to 5 are techniques for immobilizing the neck and limbs, making it difficult to immobilize them quickly. [Means for solving the problem]

[0008] Therefore, the inventors conducted extensive research into a fixation table that can quickly and stably fix animals, and discovered that animals can be quickly and stably fixed by clamping them between at least two L-shaped fixation devices, thereby completing the present invention.

[0009] [1] The object of the present invention is to A restraint for restraining an animal, The base and one or more pairs of fasteners; The one or more pairs of fixing devices are movable on the base so that one of the pair of fixing devices and the other of the pair of fixing devices sandwich the animal. fixed stand The purpose is to provide

[0010] By using the immobilization table according to the present invention, animals can be immobilized quickly and stably.

[0011] [2] In the fixing base described in [1], each of the one or more pairs of fixing devices may include a flat plate that contacts the base and a wall that extends in a direction away from the plane of the flat plate. In the fixing base described in [1], the wall surface of one of the walls of the pair of fixing tools may face the wall surface of the other wall of the pair of fixing tools.

[0012] [3] In the fixing base described in [1], each of the one or more pairs of fixing devices may include fixing means capable of temporarily fixing the respective fixing devices to the fixing base.

[0013] [4] The fixing base described in [1] may further comprise a biasing means for applying a force from one of the pair of fixing tools toward the other of the pair of fixing tools.

[0014] [5] In the fixture base described in [4], the biasing means may be a spring or an actuator. [Brief explanation of the drawings]

[0016] definition For convenience, certain terms used in this application are collected here. Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise.

[0017] Although the numerical ranges and parameters set forth in the present invention are approximate, the numerical values ​​set forth in the specific examples are reported as precisely as possible. However, any numerical value inherently contains certain errors necessarily resulting from the standard deviation found in each test measurement. Also, as used herein, the term "about" generally means within 10%, 5%, 1%, or 0.5% of a given value or range. Alternatively, the term "about" means within an acceptable standard error as considered by one of ordinary skill in the art.

[0018] In some embodiments, the animal may be, but is not limited to, a reptile, a bird, or a mammal. In some embodiments, the mammal is a small mammal (e.g., a mouse, a rat). In some embodiments, the animal comprises an animal body part. In some embodiments, the animal body part comprises a head.

[0019] Areas A, A', A'', A''', and A'''' shown in some of the drawings are schematic representations of the areas formed between one or more pairs of fixtures in a plan view, where an animal is placed or fixed on the fixture base, and are not patterns on the fixture base.

[0020] Hereinafter, embodiments of the present invention will be described. The following embodiments are merely examples, and the scope of the present invention is not limited to those shown in the following embodiments. Note that, to avoid repetition, explanations of similar content will be omitted as appropriate.

[0021] Animal fixing stand 1 1 and 2 are a top perspective view and a bottom perspective view, respectively, of a fixation table 1 for immobilizing an animal according to this embodiment. FIG. 3 is a plan view of the fixation table 1 for immobilizing an animal according to this embodiment. FIG. 4 is a plan view of the fixation table 1 having an area A' that is larger than the area A between the fixtures 20A and 20B shown in FIG. 3. FIG. 5 is a plan view of the fixation table 1 having an area A'' that is tapered in plan view.

[0022] Fixed stand 1 The fixed table 1 includes a base 10 and a pair of fixtures 20. The shapes of the areas (A, A', and A'') can be changed by moving the pair of fixtures 20.

[0023] Base 10 The base 10 according to this embodiment has a front surface 10a, a back surface 10b, a side surface 10c, and two feet 12. The base 10 according to this embodiment is rectangular in plan view, but may have other shapes. The base 10 according to this embodiment has two feet 12 extending from the front surface 10a to the back surface 10b on each of two opposing edges, and may have multiple feet 12 corresponding to all edges, or may have no feet at all. In this embodiment, the base 10 has four openings 11 penetrating between the front surface 10a and the back surface 10b, but the base 10 may have four or more openings.

[0024] Pair of fixtures 20 The pair of fixtures 20 according to this embodiment includes one fixture 20A and the other fixture 20B. In this embodiment, each of the pair of fixtures 20, 20A and 20B, includes a flat plate 22A and 22B that contacts the base 10, and a wall 23A and 23B that extends away from the flat surface 22a of each of the flat plates 22A and 22B.

[0025] Walls 23A and 23B have wall surfaces 23aA and 23aB, respectively, that face the animal when the animal is sandwiched. Wall surface 23aA of wall 23A of one of the pair of fixtures 20A faces wall surface 23aB of wall 23B of the other of the pair of fixtures 20B.

[0026] Each of the flat plates 22A and 22B according to this embodiment has two guide grooves 21, but each of the flat plates 22A and 22B may have two or more guide grooves. The guide groove 21 according to this embodiment penetrates the flat plate 22 in the thickness direction. The guide groove 21 according to this embodiment is a straight groove extending perpendicular to the wall 23, but is not limited to this and may have a groove of another shape (for example, a curved groove or a groove having a partial curve) as long as it allows each of the pair of fixing devices 20, 20A and 20B, to move so as to change the shape of the region A.

[0027] Fixing means 30 The pair of fasteners 20 are placed on the surface 10a of the base 10 so that each guide groove 21 is aligned with the corresponding opening 11, and the pair of fasteners 20 are fixed to the base 10 by fastening means 30 that passes through the openings 11 corresponding to each guide groove 21. The fastening means 30 in this embodiment can temporarily fasten the pair of fasteners 20 to the base 10, and can release the fastening between the pair of fasteners 20 and the base 10 in order to move the pair of fasteners 20. The fastening means 30 in this embodiment is composed of a bolt 31 and a nut 32, but other fastening means may be used.

[0028] The fixation by the fixing means 30 can be released to increase or decrease the distance between the pair of fixing devices 20. Increasing the distance between the pair of fixing devices 20 makes it easier to place the animal on the fixing table 1, while decreasing the distance between the pair of fixing devices 20 allows the animal to be fixed to the fixing table 1. Furthermore, the fixing table 1 according to this embodiment allows the pair of fixing devices 20 to be moved so that the distance between them becomes tapered in plan view (for example, area A'' in FIG. 5), thereby enabling fixing that follows the shape of the animal.

[0029] In the fixed base 1 of this embodiment, the pair of fixtures 20 and the base 10 each have a guide groove 21 and an opening 11, but the pair of fixtures 20 and the base 10 may also each have an opening 11 and a guide groove 21, as in the fixed base 1 of another embodiment described below.

[0030] Animal Fixation Platform 101 FIG. 6 shows a plan perspective view of a fixation table 101 for fixing a part of an animal's body according to another embodiment. The fixation table 101 according to this embodiment includes four pairs of fixation devices 120. The fixation table 101 according to this embodiment includes a biasing means 133 corresponding to each fixation device. The biasing means 133 applies a force that causes one of the pair of fixation devices (e.g., 120A) to move toward the other of the pair of fixation devices (e.g., 120B). The biasing means 133 according to this embodiment is a spring, but may also be an actuator. Because the individual fixation devices according to this embodiment can move independently of each other, the fixation table 101 has high adaptability to the shape of the animal, enabling more reliable fixation.

[0031] Each pair of fixtures 120 according to this embodiment has a protective plate 125 on the wall surface 123a. The protective plate 125 is made of a softer material than the fixtures, thereby reducing the risk of injury to the animal.

[0032] Since each pair of fixtures 120 and the corresponding elements have the same structure, to avoid redundant description, only fixtures 120A and 120B and the elements related to these fixtures will be described. Fixture 120A

[0033] FIG. 7(a) shows a bottom perspective view of fixture 120A provided on fixture base 101, FIG. 7(b) shows a left side view of fixture 120A, and FIG. 7(c) shows a front view of fixture 120A.

[0034] The fixture 120A according to this embodiment is composed of an upper part 126, a bottom part 128, and a connecting part 127 provided between the upper part 126 and the bottom part 128. The upper part 126, the connecting part 127, and the bottom part 128 may be connected to each other by any connecting means (for example, adhesive, welding, pins, rods, screws, and bolts).

[0035] The upper portion 126 includes a flat plate 122 and a wall 123 extending in a direction away from a plane 122a of the flat plate 122 (see also FIG. 6). The connecting portion 127 moves in a guide groove 121, which will be described later, and the bottom portion 128 moves in a tunnel 129, which will be described later. The width W of the connecting portion 127 in a front view (or a rear view) is 127 is the width W of the guide groove 121 121 The width W of the bottom 128 in front view is smaller than the width W of the bottom 128 in front view, so that the bottom 128 can move within the guide groove 121. 128 is the width W of the tunnel 129 129 The width W of the bottom 128 in front view is smaller than the width W of the bottom 128, so that the bottom 128 can move within the guide groove 121. 128 is the width W of the guide groove 121 121 By being wider than the width of the tunnel 129, the bottom 128 is prevented from slipping out of the guide groove 121, and stable movement of the fixing device 120A is possible.

[0036] FIG. 7(d) shows a top perspective view of fixture 120A with pivot axis 136, FIG. 7(e) shows a plan view of fixture 120A with pivot axis 136, and FIG. 7(f) shows a plan view of fixture 120A with upper portion 126 pivoted radially about pivot axis 136.

[0037] The pivot axis 136 according to this embodiment is an axis that allows the upper part 126 to pivot clockwise or counterclockwise around the pivot axis 136 in a plan view. By providing the fixture 120A with the pivot axis 136, the upper part 126 can be pivoted at any angle relative to the connecting part 127 and the bottom part 128 around the pivot axis 136, which further improves the ability of the fixture to follow the animal. The pivot axis 136 may be any pivot means (for example, a pin, a rod, a screw, a bolt, or the like).

[0038] In one embodiment, the pivot 136 passes from the top 126 to the connecting portion 127 or the connecting portion 127 to the bottom 128, connecting the top 126, the connecting portion 127, and the bottom 128 to one another.

[0039] Base 110 Fig. 8 shows a plan view of the base 110 provided on the fixed base 101. Fig. 9(a) shows a cross-sectional view in the AA direction shown in Fig. 8, and Fig. 9(b) shows a cross-sectional view in the BB direction shown in Fig. 8. The base 110 shown in Figs. 8 and 9 has removable parts (such as the fixing device 120A and the biasing means 133) removed.

[0040] In one embodiment, the base 110 has one or more pairs of guide grooves 121 on the surface 110a and one or more pairs of tunnels 129 inside the base 110 corresponding to the one or more pairs of guide grooves 121. Each of the pair of guide grooves 121 is arranged so that their longitudinal central axes coincide with each other in a plan view but are spaced apart. In one embodiment, each of the pair of tunnels 129 is arranged so that their longitudinal central axes coincide with each other in a plan view but are spaced apart. In another embodiment, each of the pair of tunnels 129 is arranged so that their longitudinal central axes coincide with each other in a plan view and are communicated with each other. The base 110 has an inlet 134 on the side surface 110c for communicating each tunnel 129 with the outside of the base 110. Each guide groove 121 is connected to a tunnel 129 so that their longitudinal central axes overlap with each other in a plan view.

[0041] The base 110 shown in Fig. 8 has four pairs of guide grooves 121 (a total of eight guide grooves 121) whose central axes in the longitudinal direction coincide with each other, and the four central axes are approximately parallel to each other. The pair of guide grooves 121 are connected to tunnels 129 provided inside the base 110 so that their central axes in the longitudinal direction overlap in a plan view. The pair of tunnels 129 shown in Fig. 8 are connected to each other, and two guide grooves 121 are connected to one tunnel 129.

[0042] Width W of the guide groove 121 when viewed from the back (or front) 121 is the width W of the tunnel 129 129 The width or diameter of the biasing means 133 according to this embodiment is narrower than the width W of the guide groove 121 in a rear view (or a front view). 121 Wider than the width of tunnel 129 W 129 By being narrower than the width of the tunnel 129, the biasing means 133 is prevented from slipping out of the guide groove 121, and a stable force can be applied to the bottom part 128. Entrances 134 are provided on both ends of the tunnel 129, and the bottom part 128 and the biasing means 133 can be placed inside the tunnel 129 through the entrances 134.

[0043] In this embodiment, the inlet 134 is sealed by the lid 113 (see FIG. 6) to prevent the bottom 128 and the biasing means 133 from being ejected from the tunnel 129. In this embodiment, the inlet 134 is threaded for sealing with the lid 113, although other means may be used to achieve sealing with the lid 113.

[0044] Assembling the fixed base 101 Fig. 10 shows a plan view of a fixed base 101 including four pairs of fasteners 120, corresponding biasing means 133, and each lid 113. Fig. 11(a) shows a cross-sectional view in the AA direction shown in Fig. 10, and Fig. 11(b) shows a cross-sectional view in the BB direction shown in Fig. 10. Fig. 12 shows a plan view of a fixed base 101 having an area A'''' that is expanded more than the area A'''' between the pairs of fasteners 120 shown in Fig. 10.

[0045] The assembly procedure for the fixed base 101 will be described below, but this procedure is an example and various procedures can be used. The bottom part 128 is inserted into the tunnel 129 from the entrance 134. The connecting part 127 is connected to the bottom part 128, and the top part 126 is connected to the connecting part 127. The biasing means 133 is inserted into the tunnel 129 from the entrance 134. The entrance 134 is sealed with the lid 113. This lid 113 has a screw structure and can be moved within the tunnel 129, allowing the biasing force of the biasing means 133 to be adjusted.

[0046] The animal can be placed on the fixing table 101 by moving each of the pair of fixing devices 120 so that the spacing between them increases, and the animal can be stably fixed to the fixing table 101 by moving each of the fixing devices 120 so that the spacing between them decreases, i.e., by the biasing means 133 biasing each of the fixing devices toward the animal.

[0047] Stopper 135 FIG. 13 shows a top perspective view of the fixed base 101 equipped with the stopper 135. As shown in FIG.

[0048] The stopper 135 moves each of the pair of fixing devices 120 so that the distance between them increases, and temporarily prevents each fixing device from returning to its original position by the biasing means 133 when placing the animal on the fixing table 101. The stopper 135 according to this embodiment includes a second connecting portion 135a connectable to the first connecting portion 124 of the fixing device 120, a claw portion 135c that engages with the side surface 110c of the base 110, and an intermediate portion 135b that connects the second connecting portion 135a and the claw portion 135c. While the first connecting portion 124 and the second connecting portion 135a according to this embodiment are recessed and protruding, respectively, they may be reversed. Furthermore, the first connecting portion 124 and the second connecting portion 135a are not particularly limited as long as they are means for preventing the fixing devices from returning to their original position. While the stopper 135 according to this embodiment connects two fixing devices 120, the stopper 135 may connect to one or more fixing devices 120. [Explanation of symbols]
