Description

Technical Field

[0001] The present invention belongs to the technical field of blood sampling equipment, and in particular relates to a blood sampling device and method for animal husbandry and veterinary medicine. Background Art

[0002] Animal husbandry is a production sector that utilizes domesticated animals such as livestock and poultry, and through artificial breeding and reproduction, converts plant energy such as forage and feed into animal energy to obtain animal products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal herbs. Animal husbandry is an extremely important link in the material exchange between humans and nature. Veterinarians often need to conduct regular blood tests on different animals to determine the diseases of the animals through chemical testing of animal blood samples to avoid outbreaks of infectious diseases among livestock.

[0003] When drawing blood from animals, traditional syringes are generally used. These syringes are inconvenient to use because the operator needs to insert the needle and then continuously pull the syringe's lever to draw blood, and this requires the cooperation of two people. Later, a new single-person blood collection device was designed, which includes a syringe, a fixing frame, and a drive component. By fixing the syringe and the drive component on the fixing frame, the drive component drives the piston in the syringe, and the syringe uses the pressure difference to draw blood from the animal. However, the syringe cannot be replaced when using this device. When blood needs to be drawn from a large number of animals, the inside of the syringe needs to be constantly cleaned, which is a cumbersome operation. In addition, the syringe is prone to incomplete cleaning, resulting in contamination of the blood sample, which leads to inaccurate measurement results. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a blood collection device and method for animal husbandry and veterinary medicine, which can be used by one person to collect blood, and is convenient for replacing syringes without cleaning the syringe, thereby avoiding contamination of blood samples and causing inaccurate measurement results.

[0005] The technical solution of the present invention includes a shell, a first elastic telescopic component and a sliding component. The inner lower end surface of the shell is provided with a groove, the lower end surface of the shell inside the groove is provided with a through hole, the outer wall of the shell is provided with a sliding groove along the length direction, the first elastic telescopic component, and the fixed ends of the first elastic telescopic component are both arranged on the upper end surface inside the shell. The telescopic end of the first elastic telescopic component cooperates with the groove to fix the syringe, and the needle of the syringe extends out of the shell through the through hole. The sliding component includes a sliding plate, a rope and a connecting piece. The sliding plate is arranged on the outer wall of the shell, and the sliding plate slides with the sliding groove. A protrusion is provided on the sliding plate. The connecting piece is located inside the shell, and the connecting piece is detachably connected to the piston rod of the syringe. One end of the rope is connected to the sliding plate, and the other end of the rope passes through the upper end surface of the shell and extends into the interior of the shell and is connected to the connecting piece. When the sliding plate slides outside the shell, the piston rod is pulled by the rope and the connecting piece, so that the syringe is used for blood collection.

[0006] Furthermore, the outer wall of the shell is also provided with a limit plate, which is slidably connected to the sliding groove and is located below the sliding plate. The limit plate adjusts the sliding distance of the sliding plate, thereby controlling the blood collection amount of the syringe. A limit component is provided on the limit plate, and the limit component controls whether the limit plate can slide on the sliding groove.

[0007] Furthermore, the outer side wall of the shell is provided with scale lines along the length direction, and the scale lines are located next to the sliding groove. The limit plate adjusts the blood collection volume of the syringe according to the scale lines.

[0008] Furthermore, the groove is stepped to accommodate syringes of various specifications, and there are multiple scale lines to match syringes of various specifications.

[0009] Furthermore, a protective component is provided under the shell to prevent the needle of the syringe from injuring people. The protective component includes multiple second elastic extension components and a protective ring. The fixed ends of the multiple second elastic extension components are all connected to the lower end surface of the shell, and the telescopic ends of the multiple second elastic extension components are all connected to the protective ring. The needle of the syringe can pass through the protective ring.

[0010] Furthermore, an anti-slip pad is provided on the protective ring.

[0011] Furthermore, the first elastic extension component and the second elastic extension component both include a fixed tube, a sliding rod and a spring. The sliding rod is inserted into the fixed tube, and the sliding rod and the fixed tube are clearance-matched. The spring is located in the fixed tube, and the spring squeezes the sliding rod to make the sliding rod extend out of the fixed tube.

[0012] The present invention also provides a blood sampling method for animal husbandry and veterinary medicine, comprising the following steps:

[0013] Step 1: Insert the syringe into the housing, so that the needle of the syringe extends out of the housing through the groove. One end of the needle of the syringe barrel is limited by the groove. Then, the first elastic telescopic component is used to squeeze the end of the syringe barrel away from the needle to fix the syringe in the housing. After the syringe is fixed, connect the connecting piece to the piston rod of the syringe.

[0014] Step 2: When collecting blood, the staff member holds the housing and places the thumb on the protrusion on the sliding plate, then inserts the needle into the animal's body, and presses the protrusion with the thumb to move toward one end of the needle. At this time, the sliding plate moves and pulls the piston rod through the rope and the connecting piece to collect blood;

[0015] Step 3: After blood collection is completed, separate the connector and piston rod, remove the syringe, and reinstall the new syringe according to step 1.

[0016] The technical solution provided by the embodiment of the present invention has the following advantages compared with the existing technology:

[0017] When using the blood collection device of the present invention, the syringe is inserted into the housing so that the needle of the syringe extends out of the housing through the groove. One end of the needle of the syringe barrel is limited by the groove, and then the syringe barrel is squeezed away from the end of the needle by the first elastic telescopic component to fix the syringe in the housing. After the syringe is fixed, the connector is connected to the piston rod of the syringe. When collecting blood, the staff holds the housing with the thumb on the sliding plate, and then inserts the needle into the animal body. The thumb presses the sliding plate to move toward one end of the needle. At this time, the sliding plate moves and pulls the piston rod through the rope and the connector to collect blood. After the blood collection is completed, the connector and the piston rod are separated, the syringe is taken out, and a new syringe is reinstalled. Compared with the prior art, the present invention can replace the syringe in the blood collection device without cleaning the syringe, thereby avoiding contamination of the blood sample and causing inaccurate measurement results.

[0018] Other advantages, objectives and features of the present invention will be reflected in part from the following description and will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A specific embodiment of the present invention is described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] In the description of the embodiments of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0031] like Figures 1 to 6 As shown, the present invention provides a blood collection device for animal husbandry and veterinary medicine, including a shell 1, a first elastic telescopic component and a sliding component. The inner lower end surface of the shell 1 is provided with a groove 2, and the lower end surface of the shell 1 inside the groove 2 is provided with a through hole. The outer wall of the shell 1 is provided with a sliding groove 3 along the length direction, the first elastic telescopic component, the fixed end of the first elastic telescopic component is both provided on the upper end surface inside the shell 1, the telescopic end of the first elastic telescopic component cooperates with the groove 2 to fix the syringe, and the needle 5 of the syringe extends out of the shell 1 through the through hole. The sliding component includes a sliding plate 7, a rope 9 and a connecting member 10. The sliding plate 7 is provided on the outer wall of the shell 1, and the sliding plate 7 slides with the sliding groove 3. The sliding plate 7 is provided with a protrusion 8. The connecting member 10 is located inside the shell 1 and is detachably connected to the piston rod 6 of the syringe. One end of the rope 9 is connected to the sliding plate 7, and the other end of the rope 9 passes through the upper end surface of the shell 1 and extends into the interior of the shell 1 and is connected to the connecting member 10. When the sliding plate 7 slides outside the shell 1, the piston rod 6 is pulled by the rope 9 and the connecting member 10, so that the syringe draws blood.

[0032] When using the blood collection device of the present invention, the syringe is inserted into the housing 1, and the needle 5 of the syringe is extended out of the housing 1 through the groove 2. One end of the needle 5 of the syringe barrel 4 is limited by the groove 2. Then, the syringe barrel 4 is squeezed away from one end of the needle 5 by the first elastic telescopic component to fix the syringe in the housing 1. After the syringe is fixed, the connector 10 is connected to the piston rod 6 of the syringe. When blood is collected, the staff holds the housing 1 and places the thumb on the protrusion 8 on the sliding plate 7. Then, the needle 5 is inserted into the animal body and the thumb presses the protrusion 8 to move toward one end of the needle 5. At this time, the sliding plate 7 moves and pulls the piston rod 6 through the rope 9 and the connector 10 to collect blood. After the blood collection is completed, the connector 10 and the piston rod 6 are separated, the syringe is removed, and a new syringe is reinstalled. Compared with the prior art, the present invention can replace the syringe in the blood collection device without cleaning the syringe, avoiding contamination of the blood sample, thereby causing inaccurate measurement results.

[0033] Optionally, a long opening is opened along the length direction of the housing 1 to facilitate the placement of the syringe into the housing 1 and to facilitate viewing the amount of blood collected by the syringe.

[0034] It can be understood that the groove 2 is used to fix the syringe barrel 4, and the syringe barrel 4 is generally cylindrical, so the cross section of the groove 2 is circular.

[0035] In the embodiment provided by the present invention, the outer wall of the shell 1 is also provided with a limit plate 11, which is slidably connected to the sliding groove 3, and the limit plate 11 is located below the sliding plate 7. The limit plate 11 adjusts the sliding distance of the sliding plate 7, thereby controlling the blood collection amount of the syringe. A limit component is provided on the limit plate 11, and the limit component controls whether the limit plate 11 can slide on the sliding groove 3.

[0036] In actual operation, the sliding plate 7 may be displaced excessively due to various reasons, such as force control, animal struggle, etc. Therefore, a limit plate 11 is provided on the sliding groove 3 to limit the sliding distance of the sliding plate 7, thereby avoiding excessive displacement of the sliding plate 7 and causing excessive blood collection.

[0037] In the embodiment provided by the present invention, the outer wall of the housing 1 is provided with scale lines along the length direction, the scale lines are located next to the sliding groove 3, and the limiting plate 11 adjusts the blood collection volume of the syringe according to the scale lines.

[0038] It can be understood that although the amount of blood collected can be controlled by observing the scale on the syringe, it is not easy to control due to problems such as strength control and animal struggle. Therefore, scale lines are set on the outer wall of the shell 1, and the position of the limit plate 11 is adjusted by the scale lines to control the moving distance of the sliding plate 7, thereby controlling the amount of blood collected by the syringe, and there is no need to always pay attention to the scale on the syringe.

[0039] In the embodiment provided by the present invention, the groove 2 is stepped to accommodate syringes of various specifications, and there are multiple scale lines to match syringes of various specifications.

[0040] It is understood that the blood collection device of the present application is designed for blood collection from different animals, and different animals require syringes of different specifications. For example, for small animals such as chickens, ducks, geese, and rabbits, a small-sized syringe is required, and the diameter of the syringe barrel 4 of a small-sized syringe is generally about 1 cm. For large animals such as cattle, horses, and sheep, a large-sized syringe is required, and the diameter of the syringe barrel 4 of a large-sized syringe is generally about 2 cm. Therefore, to accommodate syringes of different specifications, the groove 2 is configured in a stepped shape to secure syringes of different diameters. For example, the diameter of the deepest part of the groove 2 is 1 cm, gradually decreasing to 1.5 cm and 2 cm upwards. The specific dimensions are determined based on the diameter of the syringe barrel 4 of different specifications to ensure that the syringe 4 does not easily slide after being secured.

[0041] It can be understood that the lengths of syringes of different specifications are also inconsistent. When the blood collection volume needs to be controlled, the scales used by syringes of different specifications are also inconsistent. Therefore, different scale lines need to be set on the outer wall of the shell 1 according to the syringes of different specifications to ensure the control of the blood collection volume of different syringes.

[0042] It is understandable that the syringe needle 5 is dangerous, especially when blood is collected from an animal. The needle 5 carries the animal's blood, and if it accidentally injures a person, it can easily cause disease. Therefore, the needle 5 needs to be protected to avoid injuring a person, but it must not affect the needle 5's penetration into the animal's body. In the embodiment provided by the present invention, a protective assembly is provided below the housing 1 to prevent the syringe needle 5 from injuring a person. The protective assembly includes multiple second elastic extension assemblies and a protective ring 12. The fixed ends of the multiple second elastic extension assemblies are all connected to the lower end surface of the housing 1, and the telescopic ends of the multiple second elastic extension assemblies are all connected to the protective ring 12, so that the syringe needle 5 can pass through the protective ring 12.

[0043] Specifically, when blood needs to be collected from an animal, the protective ring 12 is placed at the position where the animal needs to have its blood collected, and the blood collection device is pressed. At this time, the second elastic extension component contracts, allowing the needle 5 to pass through the protective ring 12 and insert into the animal's body. After the blood collection is completed, the needle 5 is pulled out, and the second elastic extension component extends, so that the needle 5 is located between the protective ring 12 and the shell 1, preventing the needle 5 from injuring others.

[0044] In the embodiment provided by the present invention, an anti-slip pad is provided on the protection ring 12 .

[0045] It can be understood that the provision of the anti-slip pad can act on the animal while the protective ring 12 shields the needle 5, thereby preventing the blood collection device from being offset due to the animal's struggle during blood drawing.

[0046] In the embodiment provided by the present invention, the first elastic stretching component and the second elastic stretching component both include a fixed tube 13, a sliding rod 15 and a spring 14. The sliding rod 15 is inserted into the fixed tube 13, and the sliding rod 15 and the fixed tube 13 are loosely matched. The spring 14 is located in the fixed tube 13, and the spring 14 squeezes the sliding rod 15 so that the sliding rod 15 extends out of the fixed tube 13.

[0047] The present invention also provides a blood sampling method for animal husbandry and veterinary medicine, comprising the following steps:

[0048] Step 1: Insert the syringe into the housing 1, so that the needle 5 of the syringe passes through the groove 2 and extends out of the housing 1. One end of the needle 5 of the syringe barrel 4 is limited by the groove 2. Then, the first elastic telescopic component is used to squeeze the end of the syringe barrel 4 away from the needle 5 to fix the syringe in the housing 1. After the syringe is fixed, connect the connecting piece 10 to the piston rod 6 of the syringe;

[0049] Step 2: When collecting blood, the staff member holds the housing 1 and places the thumb on the protrusion 8 on the sliding plate 7, then inserts the needle 5 into the animal's body, and presses the protrusion 8 with the thumb to move toward one end of the needle 5. At this time, the sliding plate 7 moves and pulls the piston rod 6 through the rope 9 and the connecting piece 10 to collect blood;

[0050] Step 3: After the blood collection is completed, separate the connector 10 and the piston rod 6, remove the syringe, and reinstall a new syringe according to step 1.

[0051] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0052] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art.
