Abstract
Description
Technical Field
[0001] This utility model relates to the field of canine immunization detection technology, and in particular to a sample application device for canine immunization detection. Background Technology
[0002] In canine immunization testing, sampling swabs are typically used to collect throat and anal samples from infected dogs. The collected swabs are then placed in a diluent and stirred to thoroughly wash away the samples. The diluent containing the samples is then added dropwise to various types of immunoassay reagents. The type of virus carried by the infected dog is determined based on the results displayed by the reagents. Currently, the sampling tools and dilution reagents involved in this process are mostly individually packaged, resulting in low overall integration and making them inconvenient to carry and operate on-site.
[0003] In the existing canine immunization testing process, after sampling, the swab needs to be manually shaken and rotated in the diluent. This operation is prone to liquid splashing, which not only affects the sample elution efficiency but may also cause virus leakage, posing a biosafety risk. Secondly, when adding diluted samples to different test kits, there is a lack of a unified quantitative control mechanism, making it difficult to ensure the consistency of the amount added each time, thus introducing human error and affecting the accuracy and comparability of the test results. Utility Model Content
[0004] This invention provides a sample application device for canine immune detection, which solves the problem that after sampling, the swab needs to be manually shaken and rotated in the diluent, which can easily lead to liquid splashing, affecting sample elution efficiency and potentially causing virus leakage, posing a biosafety risk. Secondly, when adding diluted samples to different test kits, there is a lack of a unified quantitative control mechanism, making it difficult to ensure the consistency of the amount added each time, thus introducing human error and affecting the accuracy and comparability of test results.
[0005] This utility model provides a sample dispensing device for canine immune detection, specifically including: a reagent dropper, a first side edge on the upper left side of the reagent dropper, a reagent drop hole at the lower end of the reagent dropper, a sealing cap tightly fitted to the lower end of the reagent dropper, a sealing aluminum foil sheet sealingly attached to the upper opening of the reagent dropper, a quantitative push tube fixedly connected below the first side edge, a piston tightly slidably connected inside the quantitative push tube, the bottom of the quantitative push tube connected to the inside of the reagent dropper via a gas supply pipe, a push tube air inlet at the bottom of the quantitative push tube, a one-way gas valve with an upward outlet fixedly connected inside the push tube air inlet, a one-way gas valve with a downward outlet fixedly connected inside the gas supply pipe, and a push plate connected to the upper end of the piston via a push rod.
[0006] Furthermore, the reagent dropper has a second side edge on the upper right side, and a plug opening is provided through the center of the second side edge, with a sealing plug tightly inserted inside the plug opening.
[0007] Furthermore, a sealing sleeve is fixedly connected to the lower part of the second side edge.
[0008] Furthermore, a sampling tag is rotatably connected through the center of the sealing plug, and a rotating handle is fixedly connected to the upper end of the sampling tag, with the lower half of the sampling tag located inside the encapsulation sleeve.
[0009] Furthermore, a top spring is sleeved on the upper push rod of the piston, the upper end of the top spring is fixedly connected to the push plate, and the lower end of the top spring is fixedly connected to the upper surface of the first side edge.
[0010] Furthermore, the first side edge has an external perforation that connects to a quantitative push tube.
[0011] This invention provides a sample application device for canine immune detection, which has the following beneficial effects: This invention improves upon traditional testing and sampling tools by highly integrating the sampling tag, sealing sleeve, and reagent dropper, thus combining sampling, dilution, and sample addition into one tool, making it more convenient for staff to carry and operate on-site.
[0012] In addition, by using a sealing plug in conjunction with the sealing aluminum foil at the top of the reagent dropper, a closed elution chamber is formed after the sampling stencil is inserted. When the handle is rotated to elute the sample, the operation is carried out in a closed environment, avoiding the risk of diluent spilling due to shaking, preventing virus leakage, and greatly improving the safety of the test.
[0013] In addition, it has a quantitative gas delivery function. By pressing down the push plate, a fixed volume of air preset in the quantitative push tube can be forced into the reagent dropper through the piston, thereby smoothly pushing out an equal amount of sample liquid from the reagent dropper hole, ensuring that the liquid volume added to different test reagents is highly consistent and eliminating volume errors caused by human factors.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example 1: Please refer to Figures 1 to 6 : This invention discloses a sample dispensing device for canine immune detection, comprising: a reagent dropper 1, a first side edge 2 on the upper left side of the reagent dropper 1, a reagent drop hole 101 at the lower end of the reagent dropper 1, a quantitative push tube 202 fixedly connected below the first side edge 2, a piston 205 tightly slidably connected inside the quantitative push tube 202, the bottom of the quantitative push tube 202 being connected to the inside of the reagent dropper 1 via a gas supply pipe 204, a push tube air inlet 203 at the bottom of the quantitative push tube 202, a one-way valve with an upward outlet fixedly connected inside the push tube air inlet 203, a one-way valve with a downward outlet fixedly connected inside the gas supply pipe 204, a push plate 206 connected to the upper end of the piston 205 via a push rod, and a sleeve of the push rod at the upper end of the piston 205. The top spring 207 is fixedly connected to the push plate 206 at its upper end and to the upper surface of the first side edge 2 at its lower end. The first side edge 2 has an external perforation 201 that is connected to the quantitative push tube 202. The quantitative push tube 202, piston 205, gas supply pipe 204 with built-in one-way gas valve and top spring 207 together constitute a quantitative pneumatic drive system. During operation, pressing down the push plate 206 will force a fixed volume of air preset in the quantitative push tube 202 into the reagent dropper 1 through the piston 205, thereby smoothly pushing out an equal amount of sample liquid from the reagent dropper hole 101. This quantitative mechanism ensures that the liquid volume added to different test reagents is highly consistent and reduces volume errors caused by human factors.
[0020] In this embodiment, the lower end of the reagent dropper 1 is tightly fitted with a sealing cap 102, and the upper opening of the reagent dropper 1 is sealed with a sealing aluminum foil 103. The sealing plug 4 cooperates with the sealing aluminum foil 103 at the upper end of the reagent dropper 1, forming a completely closed elution chamber after the sampling stencil 5 is inserted. When the handle 501 is rotated to perform sample elution, all operations are completed in a closed environment, avoiding the risk of diluent spilling due to shaking, effectively preventing potential virus leakage, and greatly improving the biosafety of the detection process.
[0021] In Example 2, based on Example 1, a second side edge 3 is provided on the upper right side of the reagent dropper 1. A plug port 301 is provided through the center of the second side edge 3. A sealing plug 4 is tightly inserted into the plug port 301. A sealing sleeve 302 is fixedly connected below the second side edge 3. A sampling stick 5 is rotatably connected through the center of the sealing plug 4. A rotating handle 501 is fixedly connected to the upper end of the sampling stick 5. The lower half of the sampling stick 5 is located inside the sealing sleeve 302. By highly integrating the sampling stick 5, the sealing sleeve 302 and the reagent dropper 1, the functions of sampling, dilution and sample addition are integrated, changing the traditional separate packaging mode of sampling tools and dilution reagent kits in testing, making it convenient for staff to carry and operate on-site.
[0022] The working principle of this embodiment is as follows: During operation, firstly, the sampling stencil 5 is pulled out through the sealing plug 4 by rotating the handle 501. Sampling is then performed through the sampling stencil 5, which is then inserted into the reagent dropper 1, ensuring the sealing plug 4 seals the opening of the reagent dropper 1. At this point, the head of the sampling stencil is submerged in the diluent of the reagent dropper 1. Rotating the handle 501 allows for sample elution in a sealed environment, preventing liquid spillage and virus leakage. For quantitative sample addition, the sealing cap 102 is removed, and the push plate 206 is pressed down, driving the piston 205 to push the quantitative push tube 20. 2. The air flows downwards, and a fixed volume of air is forced into the upper space of the reagent dropper 1 through the one-way air valve in the air supply pipe 204. The air pressure causes the sample liquid at the bottom of the tube to be smoothly discharged from the reagent dropper hole 101, achieving accurate sample addition. Since the stroke of the piston 205 is fixed, the volume of air pressed in each time is constant, thus ensuring the consistency of the liquid addition each time. After the push plate 206 is released, the top spring 207 pushes the piston 205 to reset, and external air is drawn into the quantitative push tube 202 through the one-way air valve of the push tube air inlet 203, preparing for the next sample addition.
