Description

Technical Field

[0001] The utility model relates to the technical field of bird brain surgery experiment fixation devices, in particular to a body restraint device for short-beaked bird brain stereotactic surgery experiments. Background Art

[0002] During neurophysiological research on birds, the brain and body of the bird need to be fixed before surgery. The experimental subjects are often small, short-beaked birds, such as zebra finches. For example, when conducting experiments on zebra finches, the operation process is to first anesthetize the zebra finch and use a brain stereotaxic device to fix the head of the zebra finch. After positioning and fixation, the state is as follows: "The two sides of the zebra finch's head are clamped by adjustable ear bars, the tip of the zebra finch's beak is pressed against the mouth adapter of the stereotaxic device, and the junction of the zebra finch's beak and brain is pressed down by a curved rod." After the brain is fixed, in order to prevent the bird's wings and hind limbs from moving significantly during the surgical experiment, the body of the short-beaked bird needs to be restrained and fixed;

[0003] At present, there is no restraint and fixation device specifically used for bird brain experiments in the relevant field. In actual experimental processes, restraint and fixation are generally performed through homemade coverings and tapes. Since the wings and feet of short-beaked birds are relatively slender, this method will cause disturbances during the fixation process and the bird experiment process, which can easily cause damage to the bird's feathers, skin and even bones. At the same time, since the experimental process is often long, how to maintain the body temperature of the bird while fixing its body in a paralyzed state (especially in winter when performing brain surgery on birds, this problem is more obvious) also needs to be solved. Therefore, there is an urgent need for a body restraint device for stereotactic brain surgery experiments on short-beaked birds, which can effectively restrain and fix the bird's limbs without causing damage to the bird's body. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a body restraint device for stereotactic brain surgery experiments on short-beaked birds.

[0005] According to the first embodiment of the present invention, a body restraint device for stereotactic brain surgery experiments on short-beaked birds comprises:

[0010] A further technical solution is that the elastic section and the Velcro hook are symmetrically arranged at both side ends of the thermal insulation protective layer, and the decompression positioning notch is arranged between the two elastic sections.

[0011] A further technical solution is that the heating pad body includes a heating fiber layer, and a first waterproof layer and a second waterproof layer provided on both side surfaces of the heating fiber layer.

[0013] A further technical solution is to further include a power supply component and a limiting structure respectively fixedly connected to the two side ends of the heating pad body.

[0014] A further technical solution is that the power supply assembly and the bottom surface of the limiting structure are respectively provided with limiting fixing members spaced apart along the length direction.

[0015] A further technical solution is that the power supply assembly includes a shell and a battery chamber arranged in the shell, a power supply for power supply is installed in the battery chamber, and the power supply is electrically connected to the collection end.

[0016] A further technical solution is that the position-limiting fixing member is one of a soft rubber pad and a soft suction cup.

A power supply component is provided at one end of the heating pad. The power supply component does not require additional plugging in during the experimental process, and the applicable scenarios are wider and easy to carry. By setting the first restraint pad and the second restraint pad, the first limiting protrusion and the second limiting protrusion are provided on the surface of the first restraint pad. The setting of the first limiting protrusion and the second limiting protrusion can better position the short-beaked birds when they are fixed, and can also effectively prevent the feathers of the birds from extending to one side of the Velcro. The first The thermal protection layer of the restraint pad is made of soft materials such as cotton. It can not only keep warm but also effectively protect the bird's feathers, skin, claws, etc. The second restraint pad is provided with a decompression positioning notch, Velcro and elastic section.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this utility model are intended only to describe specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Example

[0039] See also Figures 1 to 2 This embodiment provides a body restraint device for use in a short-beaked bird brain stereotactic surgery experiment, comprising:

[0040] The heating pad body 200 has two ends fixedly connected to the power supply component 100 and the limiting structure 300. Preferably, the heating pad body 200 is rectangular in shape and is made of soft material. The bottom surface of the heating pad body 200 is coplanar with the bottom surface of the power supply component 100 and the limiting structure 300. The power supply component 100 and the limiting structure 300 are arranged in parallel, and the shapes of the power supply component 100 and the limiting structure 300 can be set to the same size.

[0041] By setting the heating pad body 200, during the surgical experiment on short-beaked birds, the body temperature of the birds can be maintained within a certain range, avoiding damage to the birds caused by low body temperature during the experimental anesthesia process. By setting the power supply component 100, the heating pad body 200 can be provided with power. During the experimental process, the device does not need to be plugged in additionally, and the applicable scenarios are wider and easy to carry. By setting the power supply component 100 relative to the limiting structure 300, it can be better ensured that the heating pad body 200 is in a flat state, and the fixing effect of the entire device can be achieved.

[0042] like Figure 1 As shown, in order to facilitate the description of the specific structure of the device, a Z-axis coordinate is established. It should be noted that the coordinate is only for the convenience of describing the structure of the device in this embodiment and does not limit the device itself. The top surface of the heating pad body 200 is fitted with a first restraining pad 400 in the Z-axis direction. The first restraining pad 400 is arranged on the surface of the heating pad body 200 between the power supply component 100 and the limiting structure 300. It should be noted that the first restraining pad 400 can be fixed to the top surface of the heating pad body 200 by sewing with needle and thread, or by bonding. The specific selection can be made according to actual needs and is not limited here.

[0043] A second restraint pad 500 is detachably connected to the top surface of the first restraint pad 400 in the Z-axis direction. Preferably, the width of the second restraint pad 500 is set to be the same as that of the first restraint pad 400. The second restraint pad 500 and the first restraint pad 400 are detachably connected by Velcro.

[0044] With this arrangement, a chamber for restraining short-beaked birds is formed between the first restraint pad 400 and the second restraint pad 500, effectively securing the birds. Furthermore, the middle portion of the first restraint pad 400 is made of a soft material, which effectively protects the limbs of the short-beaked birds after they are secured. The second restraint pad 500 is laterally retractable, making it easier to secure short-beaked birds of varying sizes.

[0045] For details, please refer to Figures 3 to 5 The power supply assembly 100 includes a housing 110, a battery chamber 140 disposed within the housing 110, an indicator light 130, a power switch 120, and a circuit board disposed within the housing 110. It is understood that the battery chamber 140 is used to install batteries, and the battery specifications can be selected from products available on the market and are not limited here. The positive and negative poles of the battery chamber 140 form a current loop with the circuit board, the indicator light 130, and the power switch 120 through wires. The indicator light 130 is provided to indicate whether the device is powered on, and the power switch 120 is provided to control the on / off point.

[0046] In one embodiment, one end of the heating pad body 200 is fixedly connected to the bottom of the side end surface of the power supply assembly 100, wherein the heating pad body 200 includes a heating fiber layer 210, and a first waterproof layer 220 and a second waterproof layer 230 provided on both sides of the heating fiber layer 210. The thickness of the first waterproof layer 220 and the second waterproof layer 230 are set to be the same. The first waterproof layer 240 and the second waterproof layer 250 can be made of TPU, polytetrafluoroethylene or other waterproof materials. The waterproof treatment can prevent water from damaging the carbon nanotube electric heating assembly and facilitate cleaning.

[0047] Furthermore, the heating fiber layer 210 is woven with nylon yarn and heating fiber yarn. In order to achieve a better and more stable heating effect, a heating fiber yarn is woven with weft yarn every 1.5 cm to 2.5 cm on the heating fiber layer 210. The heating fiber yarn is made of carbon nanotube yarn 211 with a diameter of 150 μm to 200 μm and an outer layer of insulating material sprayed on it. Both ends of each carbon nanotube yarn 211 are fixedly electrically connected to the collection end 212. For example, the collection end 212 can be a heating fiber yarn with a larger diameter. The collection end 212 is vertically distributed along the width of the hand warmer body 200. The two collection ends 212 are electrically connected to the batteries in the battery chamber 140 through conductive wires 213.

[0048] It can be understood that compared with heating through metal wire, the carbon nanotube yarn 211 has the advantages of high mechanical strength, high conductivity, light weight, good heating performance and low power consumption. At the same time, through the reasonable distribution of the carbon nanotube yarn 211, the heat is more uniform, and by weaving the heating fiber layer 210 with nylon thread and heating fiber thread, the thermal insulation effect of the heating fiber layer 210 is better.

[0049] Optionally, the power supply assembly 100 and the bottom surface of the limiting structure 300 are respectively provided with limiting fixing members 600 at intervals along the length direction. In the figure, three limiting fixing members are provided at equal intervals on the bottom surfaces of the power supply assembly 100 and the limiting structure 300. It should be noted that the specific number can be set according to actual needs and is not limited here. The setting of the limiting fixing member 600 is used to increase the friction between the device and the experimental table and better fix the device. Optionally, the limiting fixing member 600 can be a rubber pad made of a polymer soft rubber material or a soft suction cup;

[0050] For details, please refer to Figure 6 , a first restraining pad 400 is fitted on the surface of the heating pad body 200, and the first restraining pad 400 includes a thermal insulation protective layer 410, a Velcro surface 430 arranged at both ends of the thermal insulation protective layer 410, and a first limiting protrusion 421 and a second limiting protrusion 422 arranged on the surface of the thermal insulation protective layer 410, respectively. The first limiting protrusion 421 and the second limiting protrusion 422 are respectively arranged near the connection between the thermal insulation protective layer 410 and the Velcro surface 430, and extend from one end to the other end of the thermal insulation protective layer 410 respectively. The thermal insulation protective layer 410 can be made of cotton or silk material, and its thickness can be 1-2mm. The specific thickness can be selected according to actual needs and is not limited here. The first limiting protrusion 421 and the second limiting protrusion 422 can be semicircular long strips, which can be made of soft silicone material or cotton, and the Velcro surface 430 material can be obtained from the market.

[0051] Preferably, the Velcro surface 430 provided on both side ends of the thermal insulation protective layer 410 is mirror-set, and the shape of the Velcro surface 430 is set to be wide at both ends and narrow in the middle. At the same time, the Velcro surface 430 is seamlessly connected with the end face of the thermal insulation protective layer 410, and the Velcro surface 430 is equal in thickness to the thermal insulation protective layer 410. The first limiting protrusion 421 and the second limiting protrusion 422 are mirror-set, and the first limiting protrusion 421 and the second limiting protrusion 422 can be fixed to the surface of the thermal insulation protective layer 410 by cotton thread.

[0052] With such a configuration, the first limiting protrusion 421 and the second limiting protrusion 422 can better position the short-beaked birds when fixing them. At the same time, it can also effectively prevent the feathers of the short-beaked birds from extending to the Velcro surface 430 on both sides. The setting of the Velcro surface 430 facilitates the repeated bonding connection between the first restraint pad 400 and the second restraint pad 500. The thermal protective layer 410 is made of soft materials such as cotton, which can effectively protect the feathers, skin, claws, etc. of the birds while achieving warmth.

[0053] See also Figure 7 The second restraint pad 500, which is detachably connected to the first restraint pad 400, includes a restraint limiting layer 510, elastic sections 520 and Velcro hooks 530 sequentially arranged at both ends of the restraint limiting layer 510. A pressure-reducing positioning notch 511 is defined at one end of the restraint limiting layer 510. The restraint limiting layer 510 can be woven from a soft cotton material, and the elastic section 520 can be made of an elastic material. The provision of the elastic section 520 facilitates the fixation of short-beaked birds of different body shapes.

[0054] Optionally, the Velcro hook surface 530 is mirrored at both side ends of the restraint and limiting layer 510, and the shape of the Velcro hook surface 530 is the same as that of the Velcro fur surface 430, and the shape of the Velcro hook surface 530 is set to be wide at both ends and narrow in the middle. At the same time, the Velcro hook surface 530 is seamlessly connected with the end face of the elastic section 520, and the Velcro hook surface 530 is equal in thickness to the restraint and limiting layer 510. The elastic section 520 and the Velcro hook surface 530 are symmetrically arranged at both side ends of the thermal protection layer 410, and the decompression positioning notch 511 is arranged between the two elastic sections 520.

[0055] Optionally, the shape of the decompression positioning notch 511 can be semicircular, semi-elliptical or triangular. It should be noted that, as long as the neck of short-beaked birds can be decompressed, its specific shape and opening size can be selected according to actual needs and are not limited here.

[0056] With such a configuration, the Velcro makes it convenient for experimenters to fix the body of the bird and reuse the device. The elastic section 520 makes it convenient to fix short-beaked birds of different physiques. The decompression positioning notch 511 makes it convenient to position the bird's head during surgical experiments. At the same time, the pressure of the restraint limiting layer on the bird's neck is reduced, ensuring the bird's normal breathing. The decompression positioning notch 511 can be used to judge the bird's breathing condition during the experiment.
