Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown, this disclosure discloses a suspended cynomolgus monkey restraint device, including at least two suspension supports, a support frame, horizontal straps 4, vertical straps 8, and an adjustable binding member. At least two suspension supports are installed parallel to each other at intervals; the support frame includes an upper bracket and a lower bracket, the upper bracket being mounted on the at least two suspension supports, and the lower bracket being height-adjustably mounted on the upper bracket; at least two horizontal straps 4 are installed parallel to each other at intervals on the upper bracket; one end of each vertical strap 8 is connected to a suspension support, and the other end extends and crosses and is adhesively connected to the at least two horizontal straps 4; the adjustable binding member is adjustablely mounted on the upper bracket and used to restrain the cynomolgus monkey on the upper bracket.

[0022] The number of horizontal straps 4 can be 2, 3, 4, 5, 6, 7, 8, 9, or 10. Multiple horizontal straps can form a backrest while also preventing the cynomolgus monkey from detaching from the upper support. Of course, the number of horizontal straps is not limited to this; an appropriate number of horizontal straps can be installed according to work requirements.

[0023] The number of suspension supports can be 2, 3, or 4, etc. These supports provide structural support to the support frame, allowing it to be suspended. The number of suspension supports is not limited to these; an appropriate number can be installed according to work requirements.

[0024] like Figure 1 , 2 As shown, the number of vertical straps 8 can be 1, 2, 3, 4, 5, 6, or 7. When multiple vertical straps are used, they are arranged in parallel with intervals. Of course, the number of vertical straps is not limited to this; an appropriate number of vertical straps can be installed according to work requirements.

[0025] One installation method for vertical straps: When multiple suspension supports are installed in parallel with vertical spacing, one end of the vertical strap is connected to the top suspension support, and the other end extends downward to cross and be bonded to multiple horizontal straps for fixation.

[0026] Understandably, both the horizontal and vertical straps can be elastic. Elastic straps are made of elastic fibers or latex. When compressed, they undergo a certain degree of elastic deformation. This helps provide some comfort to the cynomolgus monkey and avoids hard contact with its body.

[0027] In some embodiments of this disclosure, a structure for an adjustable binding member is provided. The adjustable binding member includes a movable strap 10 and an adjusting seat 2. The movable strap 10 is slidably mounted on one side of the upper bracket via a first movable sleeve 9; a Velcro strap 11 is provided along the length of the movable strap 10; the adjusting seat 2 is provided with an adjusting opening 221 and is movably mounted on the other side of the upper bracket corresponding to the first movable sleeve 9; wherein the movable strap 10 passes through the adjusting opening 221 and is folded, and is fixedly connected to each other by the Velcro strap 11.

[0028] like Figure 1 , 2 As shown, the hook and loop fastener may consist of a hook side 111 and a loop side 112, which are mechanically interlocked to achieve a secure connection. It is understood that vertical straps and horizontal straps can be bonded and fixed together using the hook and loop fastener.

[0029] like Figure 1 , 2 As shown, one arrangement of the hook surface 111 and the fleece surface 112 on the movable strap 10 is as follows: One end of the movable strap 10 has a hook surface 111, and the other end has a fleece surface 112. During binding, the movable end passes through the adjustment port 221 and is then bent. The movable end is then bonded and fixed to the fleece surface 112 via the hook surface 111. It can be understood that the hook surface and fleece surface are aligned along the length of the movable strap.

[0030] One structure of the adjusting seat is given. For example... Figure 1 , 2 As shown, the adjusting seat 2 includes a seat cover 21 and an adjusting frame 22. The adjusting frame 22 is provided with an adjusting port 221 and is installed on the seat cover 21.

[0031] An adjustable frame and seat cover are connected by a hinge, allowing the adjustable frame 22 and seat cover 21 to swing relative to the seat cover.

[0032] It should be noted that the first movable sleeve 9 and the seat sleeve 21 are attached to the upper support and can slide along the upper support, which makes it easy to adjust the binding position for different individual cynomolgus monkeys.

[0033] To further restrict the activities of the cynomolgus monkeys, limb restraints are added. At least one limb restraint is provided on each of the upper and lower sides of the support frame. The limb restraint includes a second movable sleeve 16 and a limb strap 17. The second movable sleeve 16 is slidably connected to the support frame, and the limb strap 17 is connected to the second movable sleeve 16. Velcro 11 is provided on both sides.

[0034] At least one limb restraint can be provided on both the upper and lower ends of the upper support. For example, there can be 2, 3, 4, 5 or 6 restraints on each side of the upper support. The limb restraints on the upper support can be used to restrain the arms and legs of the cynomolgus monkey, which can restrict the movement of the cynomolgus monkey's arms and legs and thus prevent the cynomolgus monkey from scratching the operator.

[0035] The lower support can have at least one limb restraint on each side. For example, there can be 1, 2, 3 or 4 limb restraints on each side to restrain the crab-eating macaque's legs and restrict the movement of its legs.

[0036] like Figure 1 , 2 As shown, the limb restraints 17 are used to wrap and bind the limbs of the cynomolgus monkey. One installation method for the hook surface 111 and the felt surface 112 on the limb restraints 17 is as follows: one side of the limb restraints 17 has a hook surface 111, and the other side has a felt surface 112. During binding, the limb restraints 17 wrap around the cynomolgus monkey's limbs and fix them to the support. When wrapping, the side with the hook surface 111 begins to wrap. At this time, the hook surface 111 and the felt surface 112 adhere to each other, thus binding the cynomolgus monkey's limbs to the support and restricting the monkey's limb movement.

[0037] To facilitate the placement of items, a tray 15 is added, which is detachably installed on the lower support. The detachable installation of the tray allows for separation and installation of the tray and the lower support. After separation, the tray and the lower support can be easily cleaned and disinfected.

[0038] The detachable mounting structure of the pallet includes supports 18 and plug-in plates 19. The lower support has two supports 18, and one side edge of the pallet 15 has two plug-in plates 19 corresponding to the two supports 18. The supports 18 are provided with plug-in holes. During installation, the plug-in plates 19 on the pallet are inserted into the plug-in holes on their corresponding supports 18 to achieve plug-in connection between the plug-in plates 19 and the supports, that is, the pallet is installed on the lower support.

[0039] Understandably, the plug-in plate and plug holes are connected by a plug-in joint, which facilitates quick installation and disassembly. The tray is detachably connected to the support via the plug-in plate. The tray 15 can be used to place items, such as medicines, medication administration, and medical equipment used for blood draws.

[0040] One structure of a suspension support is given. The suspension support includes a support plate 6 and suspension rods 5, with each end of the support plate 6 connected to a suspension rod 5.

[0041] Installation method of suspension rod: The suspension rod 5 is fixedly installed on the supporting surface, which can be a wall or the like. For example, the fixed installation method of the suspension rod 5 can be: one is to fix it through the wall, and the other is to pre-embed one end of the suspension rod in the wall when pouring the wall surface.

[0042] Furthermore, the suspension rod 5 can be a high-strength bolt. Installation method: Drill a hole in the wall, clean the debris from the hole, insert the expansion tube, and then tighten the high-strength bolt to open and fix the expansion tube.

[0043] It should be noted that the suspension rod extends outward relative to the wall, creating a gap between the support plate and the wall, which prevents the crab-eating monkey's back from hitting the wall.

[0044] One connection method between the support plate 6 and the suspension rod 5: one end of the suspension rod is equipped with a high-strength bolt, and the other end is equipped with a support with a screw hole. The support plate has a through hole corresponding to the screw hole. During installation, the through hole on the support plate is aligned with the screw hole on the support, and then the bolt is screwed in. When the bolt is tightened, the support plate and the suspension rod are fixedly connected.

[0045] An adjustable structure for the lower support frame is provided, with the addition of a tension adjustment element 24. The upper support frame includes two parallel, spaced-apart fixed cylinders 1; the fixed cylinders 1 are slidably connected to the support plate 6, and each fixed cylinder 1 is equipped with a tension adjustment element 24. The lower support frame includes a transverse rod 13, two support rods 12, and two telescopic rods 7. One end of each telescopic rod 7 is movably housed in a fixed cylinder 1 through the tension adjustment element 24, and the other end is bent and connected to a support rod 12. At least one transverse rod 13 is installed between the two support rods 12.

[0046] One, two, or three horizontal bars can be installed in parallel between the two support rods 12. These horizontal bars provide a support platform for the cynomolgus monkey to stand. When multiple horizontal bars are used, they can be installed in parallel with spacing. A through hole 14 is formed between adjacent horizontal bars and between the horizontal bars and the tray. When the cynomolgus monkey stands or squats on the horizontal bars, its tail can hang down through the through hole 14, providing a comfortable space for the monkey to place its tail.

[0047] The tension adjustment component 24 can loosen or tighten the telescopic rod. When the height of the lower support needs to be adjusted, the tension adjustment component is adjusted to the loose state, which releases the locking state of the telescopic rod, allowing the telescopic rod to move within the fixed cylinder. When the lower support is adjusted to the required height, the tension adjustment component is then adjusted to the tight state, which tightens the telescopic rod, and the telescopic rod is fixedly connected to the fixed cylinder.

[0048] One structure of the tension adjusting component: The tension adjusting component 24 includes a fixed sleeve 244, a threaded sleeve 242, and a tension adjusting bolt 243. The threaded sleeve 242 is installed on the side of the fixed sleeve 244 and communicates with the fixed sleeve 244; the tension adjusting bolt 243 is threadedly connected to the threaded sleeve 242. The fixed sleeve 244 is installed on the fixed cylinder 1 and communicates with the fixed cylinder 1, allowing the telescopic rod to extend through the fixed sleeve and insert into the fixed cylinder.

[0049] How the tension adjustment mechanism works: To loosen the tension adjustment bolt 243: Turn the tension adjustment bolt 243 counterclockwise to unscrew the threaded sleeve 242. The tension adjustment bolt 243 will then disengage from the telescopic rod 7, releasing the tension adjustment bolt from its position on the telescopic rod. The telescopic rod 7 can then move relative to the tension adjustment component within the fixed cylinder, allowing the lower support to move relative to the upper support, thus adjusting the height of the lower support.

[0050] Tightening and fixing: Turn the tension adjusting bolt 243 clockwise, and the tension adjusting bolt 243 will be screwed into the threaded sleeve 242. The tension adjusting bolt 243 will then extend into the fixing sleeve 244. When the tension adjusting bolt is tightened, it will tighten the telescopic rod, thus fixing the telescopic rod to the fixing cylinder and the lower bracket to the upper bracket.

[0051] A structure for mounting a transverse strap to an upper support is given, such as... Figure 1 , 2 As shown, a clamp 3 is added, and the transverse strap 4 is fixed to the fixing cylinder 1 of the upper bracket through the clamp 3. The transverse strap is fixedly connected to the clamp, and the clamp is tightly fitted onto the fixing cylinder 1. This facilitates the fixing of the transverse strap to the bracket installation position.

[0052] To facilitate the installation of the fixing cylinder on the support plate 6, such as Figure 1 , 2 As shown in Figure 5, a buckle 23 and a first fastener 20 are added. A groove 61 is provided on the support plate 6 along its length. The first fastener 20 passes through the groove 61 and is threadedly connected to the fixed cylinder 1 to adjust the tightness of the connection between the fixed cylinder 1 and the support plate 6. The buckle 23 is installed on the fixed cylinder 1 to fasten to the support plate 6.

[0053] One type of fastener structure. For example... Figure 6 As shown, the first fastener 20 includes a first bolt 201, a limiting plate 202 and a threaded seat 203 installed on the fixed cylinder 1. The first bolt 201 is provided with a limiting plate 202, which is threadedly connected to the threaded seat 203. The width of the limiting plate 202 is greater than the width of the groove 61.

[0054] The sliding connection between the fixed cylinder and the support plate: First bolt tightened state: The fixed cylinder is fixedly connected to the support plate. At this time, the first bolt 201 is tightened and is threadedly fixedly connected to the threaded seat 203. The limiting plate 202 on the first bolt 201 presses against the support plate 6. Therefore, the first fastener 20 securely connects the fixed cylinder 1 to the support plate 6. The fixed cylinder cannot move relative to the support plate.

[0055] First bolt loosened state: Tighten the first bolt 201 counterclockwise, the first bolt 201 unscrews the threaded seat 203, the first bolt 201 drives the limiting plate 202 to disengage from the support plate 6, that is, release the clamping state between the limiting plate and the support plate, the fixed cylinder can move along the length direction of the slide groove, and the interval between the two fixed cylinders can be adjusted.

[0056] like Figure 1 , 2 As shown in Figures 5 and 6, the buckle 23 has an inverted L-shaped structure. The fixed cylinder is fastened to the support plate 6 by the buckle 23. When the fixed cylinder is disconnected from the support plate, the fixed cylinder can slide on the support plate with the help of the buckle 23, while the buckle can also prevent the fixed cylinder from rotating.

[0057] According to the above embodiments, the working principle of this utility model is as follows: The cynomolgus monkey to be medicated is placed on the support 1, with its feet gripping the horizontal bar 13 and its back resting against multiple horizontal straps 4, which can bend elastically. The movable end of the movable strap 10 is then passed through the adjustment port 221 on the seat cover 2, and the movable strap 10 is pulled and bent. The bent movable strap 10 is then fixed in place by Velcro 11, causing the movable strap 10 to compress and restrict the cynomolgus monkey. In other words, the movable strap, multiple horizontal straps, and the support form a restricted space, allowing the cynomolgus monkey to be restricted in its movements and thus administered medication.

[0058] Multiple adjustable restraints can be installed as needed, and these restraints can be used to confine the cynomolgus monkey to multiple lateral straps and supports.

[0059] This utility model is hung on the wall at a certain height, above the ground. When crab-eating macaques are placed on this utility model, their stress response can be reduced. The crab-eating macaques can stand quietly on the horizontal bar, reducing their sense of rejection.

[0060] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
