Description

Technical Field

[0001] This utility model relates to the field of bird blood collection devices, specifically a wild bird blood sample collection device. Background Technology

[0002] In field research on bird ecology, disease monitoring, and biodiversity conservation, blood sample collection is a crucial step in obtaining physiological indicators, pathogen detection, and genetic information.

[0003] However, traditional blood collection methods face multiple technical challenges in practice, severely limiting the efficiency and security of data collection. Specifically, existing technologies have the following shortcomings:

[0004] Firstly, birds are highly stressed organisms and are prone to violent struggle when handled by humans. Traditional methods rely on manual fixation or simple clamps, which lack adaptive constraint mechanisms for the bird's body shape. During the operation, the bird's position needs to be frequently adjusted to expose the blood collection site (such as the wing vein). Dynamic adjustments further aggravate the bird's stress response. Moreover, in an open operating environment, the bird may break free and collide with the equipment or escape, resulting in sample loss or even individual death.

[0005] Furthermore, traditional blood collection procedures require at least two people working together: one to hold the bird's body and wings still, and the other to operate the lancet. This approach has significant drawbacks in field settings. Due to the limited size of research teams in remote areas, multi-person collaboration reduces the amount of samples collected per unit time. Close contact also increases the operator's risk of exposure to zoonotic diseases such as avian influenza, especially when handling sick or weak individuals. In addition, the difference in rhythm between manual restraint and blood collection can easily lead to accidental lancet puncture or blood vessel slippage, requiring repeated attempts and increasing the bird's suffering.

[0006] Therefore, we propose a wild bird blood sample collection device to address the problems mentioned above. Utility Model Content

[0007] This invention provides a blood sample collection device for wild birds, which can solve the problem that the existing technology requires multiple people to cooperate and work manually in the collection of blood samples from wild birds. This is not only inefficient, but also poses a great safety hazard to both the operator and the birds.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A blood sample collector for wild birds includes a portable collection box, which comprises a base and a transparent box body. The transparent box body is fixedly connected to the upper part of the base. Two working windows are opened on the front of the transparent box body, and the working windows are configured to open inwards in one direction. A support frame is installed on the upper part of the base, and a main body clamping mechanism for fixing the bird body is installed on the support frame. A collection mechanism for sampling bird blood is provided on one side of the main body clamping mechanism. A wing fixing mechanism is installed on the upper part of the base, and the collection mechanism is located between the wing fixing mechanism and the main body clamping mechanism.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] This utility model discloses a blood sample collector for wild birds. The portable collection box features a transparent housing and base for stable placement. A working window on the front of the transparent housing facilitates one-handed operation for placing the bird. It also includes a wing-fixing mechanism to prevent escape and a main body clamping mechanism to ensure bird stability. The first electric telescopic rod on the support frame, through an arc-shaped pressure plate, latex pad, and pressure sensor, automatically fixes the bird, reducing pressure and minimizing the risk of injury. The shaped groove on the base, combined with the main body clamping mechanism, ensures stable fixation for birds of different sizes while enhancing the device's flexibility. The wing-fixing mechanism, consisting of a U-shaped frame and an electric push rod, automatically and synchronously fixes the bird's wings with the aid of a light-sensing sensor, facilitating single-person operation and improving ease of use. The second electric telescopic rod in the collection mechanism, in conjunction with the lifting seat, automatically generates negative pressure through mechanical compression via the clamping rod and blood collection bottle, allowing for rapid blood collection without manual suction. After blood collection, the blood collection bottle can be quickly and easily removed via a magnetic slot and magnetic block. This system not only improves the efficiency and safety of collecting blood samples from wild birds, reduces human intervention and operational complexity, but also reduces potential harm to birds and the risk of staff being infected with viruses.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] Example 1:

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A blood sample collection device for wild birds includes a portable collection box 1, which includes a base and a transparent box body. The base facilitates the stable placement of the portable collection box 1, and the transparent box body allows observation of the inside of the portable collection box 1, which is beneficial for using the collection device to collect blood from wild birds.

[0022] The transparent box is fixedly connected to the upper part of the base, covering the upper part of the base. The collection device is located inside the transparent box. The bird is placed inside the transparent box to prevent it from escaping and to improve the efficiency of blood collection.

[0023] The transparent box has two working windows on the front, which are designed to open inwards in one direction. Birds can be manually placed inside the transparent box through the working windows. The two inward-opening working windows on the front allow one-handed access for operation, while preventing birds from escaping.

[0024] A support frame 2 is installed on the upper part of the base. A main body clamping mechanism 3 for fixing the bird is installed on the support frame 2. A collection mechanism 5 for sampling bird blood is provided on one side of the main body clamping mechanism 3. A wing fixing mechanism 4 is installed on the upper part of the base. The collection mechanism 5 is located between the wing fixing mechanism 4 and the main body clamping mechanism 3.

[0025] Furthermore, the upper surface of the portable collection box 1 is provided with a shape groove suitable for the size of birds. The shape groove is located directly below the main clamping mechanism 3. The shape groove and the main clamping mechanism 3 work together to fix birds of different sizes.

[0026] The shape groove on the upper surface of the base is designed with a concave contour according to the bird's body shape, and works in conjunction with the main clamping mechanism 3. After the bird's body is embedded in the shape groove, the main clamping mechanism 3 applies pressure from top to bottom. The physical limit of the shape groove adapts to birds of different sizes. The shape groove and the clamping mechanism form a three-dimensional constraint, reducing the bird's swaying and avoiding problems of instability caused by differences in body size.

[0027] Furthermore, the main clamping mechanism 3 includes a first electric telescopic rod 31, the housing of the first electric telescopic rod 31 is fixedly connected to the support frame 2, an arc-shaped pressure plate 32 is installed at the telescopic end of the first electric telescopic rod 31, a latex pad is provided on the inner side of the arc-shaped pressure plate 32, and a pressure sensor 33 is installed between the arc-shaped pressure plate 32 and the telescopic end of the first electric telescopic rod 31.

[0028] The first electric telescopic rod 31 is fixed to the support frame 2, and its telescopic end drives the arc-shaped pressure plate 32 to press down. The latex pad on the inner side of the arc-shaped pressure plate 32 increases friction and buffers pressure. The pressure sensor 33 monitors the force of the pressure plate 62 in contact with the bird in real time to prevent excessive squeezing. The first electric telescopic rod 31 realizes automatic clamping, and the pressure sensor 33 provides feedback to adjust the clamping force, which ensures the fixing effect and avoids harming the bird.

[0029] Furthermore, the wing fixing mechanism 4 is used to fix the bird's wings. The wing fixing mechanism 4 includes a U-shaped frame 41 with its opening facing the base and its two ends fixedly connected to the base. An electric push rod 42 is fixedly installed on the upper end of the U-shaped frame 41. A rubber roller 43 is installed on the telescopic end of the electric push rod 42. A rotating seat is provided on the outside of the rubber roller 43. The telescopic end of the electric push rod 42 is fixedly connected to the rotating seat. After the bird's body is fixed, only one worker is needed to operate with one hand to pull one side of the bird's wing to unfold it and place it under the rubber roller 43. The electric push rod 42 pushes the rubber roller 43 down to fix the bird's wing.

[0030] Furthermore, a light sensor 44 for object sensing is installed at the upper end of the U-shaped frame 41, located outside the rubber roller 43. The detection end of the light sensor 44 faces the upper surface of the base. The light sensor 44 senses the movement of the bird's wings. A position detection sensor or a temperature sensor can be used. When the bird's wing enters below the light sensor 44, a temperature change can be detected. The control board then activates the wing fixing mechanism 4 to achieve automatic synchronous fixing, which is convenient and quick to operate. Then, the collection mechanism 5 is activated to collect blood samples from the bird's wing. This scheme achieves efficient and rapid collection of blood samples from wild birds without the need for multiple people, improving safety, reducing bird struggles, reducing the operational risks for workers, and reducing the possibility of workers being infected by viruses carried by birds. The semi-automatic fixing achieved by the linkage of the light sensor 44 allows a single person to complete the wing deployment and fixing, reducing manual intervention steps and improving operational efficiency.

[0031] Furthermore, the collection mechanism 5 includes a lifting seat 50, on the upper part of which a second electric telescopic rod 51 is installed. The housing of the second electric telescopic rod 51 is fixedly connected to the support frame 2. The telescopic end of the second electric telescopic rod 51 drives the lifting seat 50 to move up and down. A magnetic suction groove 53 is provided in the middle of the end of the lifting seat 50 away from the second electric telescopic rod 51. A blood collection bottle 52 is installed at the end of the lifting seat 50 with the magnetic suction groove 53. A magnetic block 55 is fixedly connected to one end of the blood collection bottle 52, and a blood collection needle 56 is fixedly connected to the other end. The bottle body of the blood collection bottle 52 is made of elastic material. A magnetic block 55 is provided inside the magnetic suction groove 53. The end of the blood collection bottle 52 connected to the magnetic block 55 cooperates with the magnetic block 55 inside the magnetic suction groove 53, which facilitates the quick installation and positioning of the blood collection bottle 52 and also facilitates quick removal and replacement. The blood collection bottle 52 is a miniature blood bottle, and one blood collection bottle 52 is used independently for each blood collection.

[0032] One end of the blood collection bottle 52 is fixed to the magnetic groove 53 via a magnetic block 55, and the other end is connected to the blood collection needle 56. A toothed ring 57 is fixed to the outside of the blood collection needle 56, and the positioning toothed groove 59 on the inner side of the clamping rod 58 locks the angle of the blood collection needle 56 through engagement with the toothed ring 57. The dual positioning via magnetic attraction and the toothed ring 57 ensures that the blood collection needle 56 is inserted vertically, preventing blood collection failure or injury to birds due to deviation. A stepper motor 61 drives a bidirectional threaded rod 60 to rotate, causing the clamping rods 58 on both sides to move closer or separate synchronously along the sliding groove. When the clamping rods 58 move closer, the inner pressure plate 62 compresses the elastic blood collection bottle 52 to expel air; when the clamping rods 58 separate, the blood collection bottle 52 rebounds, generating negative pressure to draw blood. The negative pressure is automatically generated through mechanical compression, eliminating the need for manual suction, reducing operational complexity and the risk of contamination.

[0033] Furthermore, a toothed ring 57 is fixedly connected to the outside of the blood collection needle 56. The toothed ring 57 has multiple toothed rings coaxial with the blood collection needle 56. Two clamping rods 58 are installed at one end of the lifting seat 50 near the magnetic suction groove 53. The two clamping rods 58 are symmetrically arranged on both sides of the magnetic suction groove 53. The lifting seat 50 has sliding grooves on both sides of the magnetic suction groove 53. One end of the clamping rod 58 is provided with a positioning toothed groove 59 that cooperates with the outside of the toothed ring 57. When the two clamping rods 58 are close together, the two positioning toothed grooves 59 clamp and fix the toothed ring 57, and support the blood collection needle 56 through the toothed ring 57. When the lifting seat 50 rises and falls, it drives the two clamping rods 58, the blood collection bottle 52 and the blood collection needle 56 to descend, which is beneficial to the blood collection needle 56.

[0034] Furthermore, the end of the clamping rod 58 furthest from the positioning tooth groove 59 is slidably connected to the inside of the slide groove of the lifting seat 50. A bidirectional threaded rod 60 is installed inside the lifting seat 50. The bidirectional threaded rod 60 consists of two symmetrically arranged threaded rods. The bidirectional threaded rod 60 passes through the inside of the slide groove, and a stepper motor 61 is installed at one end of the bidirectional threaded rod 60. The end of the clamping rod 58 located inside the slide groove is threadedly connected to the bidirectional threaded rod 60. A pressure plate 62 for compressing the elastic blood collection bottle 52 is provided on the inner side of the clamping rod 58. The pressure plate 62 is close to the outer side of the blood collection bottle 52. When the clamping rods 58 on both sides approach each other, the two pressure plates 62 move closer together to compress the elastic blood collection bottle 52, causing the internal gas to be discharged. When the clamping rod 58... When the positioning groove 59 clamps and fixes the toothed ring 57, the blood collection bottle 52 and the blood collection needle 56 remain stable. The second electric telescopic rod 51 pushes the lifting seat 50 down, and the blood collection needle 56 pierces the inside of the bird's wing to perform blood collection. At the same time, the stepper motor 61 drives the bidirectional screw to rotate. The bidirectional screw drives the clamping rods 58 on both sides to open outward, thereby separating the pressure plate 62 from the blood collection bottle 52. A negative pressure is generated inside the blood collection bottle 52, and the blood of the bird is drawn through the blood collection needle 56. After the collection is completed, only the blood collection bottle 52 needs to be removed. Since the clamping rods 58 on both sides are open, the magnetic block 55 of the blood collection bottle 52 can be removed simply by separating it from the magnetic block 55 inside the magnetic groove 53. The operation is simple and quick.

[0035] An adjusting screw 63 connected to the pressure plate 62 is installed on the clamping rod 58. By rotating the adjusting screw 63, the position of the pressure plate 62 can be adjusted horizontally. The adjusting screw 63 on the clamping rod 58 moves the position of the pressure plate 62 horizontally to adapt to the compression requirements of blood collection bottles 52 of different sizes.

[0036] The working principle of this wild bird blood sample collection device is as follows:

[0037] A transparent box for easy observation is fixedly connected to the top of the base and is kept stable by the support frame 2 of the base. The main clamping mechanism 3 is located on the support frame 2 on the upper part of the base, and a shape groove suitable for the size of birds is provided directly below it. When a bird is placed inside the transparent box of the portable collection box 1, after the bird's body is embedded in the shape groove, the main clamping mechanism 3 applies pressure through the first electric telescopic rod 31 to fix the bird. The two working windows on the front of the transparent box open inward in one direction, which makes it easy to put the bird into the box with one hand.

[0038] The wing securing mechanism 4 includes a U-shaped frame 41 and an electric push rod 42. The opening of the U-shaped frame 41 faces the base, and a rubber roller 43 is installed on the telescopic end of the electric push rod 42. The operator operates with one hand to unfold one side of the bird's wing and place it under the rubber roller 43. The electric push rod 42 pushes the rubber roller 43 down to secure the bird's wing.

[0039] A light sensor 44 is located at the upper end of the U-shaped frame 41 and is used to sense the movement of the bird's wings. When the bird's wings enter below the light sensor 44, the control board activates the wing fixing mechanism 4 to achieve automatic synchronous fixing. The collection mechanism 5 is located between the wing fixing mechanism 4 and the main body clamping mechanism 3. The blood collection bottle 52 is fixed to the magnetic groove 53 by the magnetic block 55, and the other end is connected to the blood collection needle 56. The toothed ring 57 is fixed to the outside of the blood collection needle 56, and the positioning toothed groove 59 on the inner side of the clamping rod 58 locks the angle of the blood collection needle 56 by engaging the toothed ring 57.

[0040] The second electric telescopic rod 51 drives the lifting seat 50 to move up and down. A magnetic groove 53 is provided in the middle of the end of the lifting seat 50 away from the second electric telescopic rod 51, where a blood collection bottle 52 is mounted. A stepper motor 61 drives a bidirectional threaded rod 60 to rotate, causing the clamping rods 58 on both sides to move closer or further apart along the sliding groove. When the clamping rods 58 move closer, the inner pressure plate 62 compresses the elastic blood collection bottle 52, expelling air; when the clamping rods 58 separate, the blood collection bottle 52 rebounds, generating negative pressure to draw blood.

[0041] When the lancet 56 pierces the inside of a bird's wing, it automatically generates negative pressure through mechanical compression, eliminating the need for manual suction, reducing operational complexity and the risk of contamination.

[0042] After collection, simply remove the blood collection bottle 52. Since the clamps 58 on both sides are open, the bottle can be removed simply by separating the magnetic block 55 of the blood collection bottle 52 from the magnetic block 55 inside the magnetic groove 53. The operation is simple and quick.

[0043] The above steps enable efficient and rapid collection of blood samples from wild birds, improving safety, reducing birds' struggles, lowering operational risks for staff, and reducing the possibility of staff being infected by viruses carried by birds.

[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
