Description

Technical Field

[0001] This utility model belongs to the technical field of test tubes for detecting pathogens in pig farming, specifically relating to test tubes for detecting pathogens in pig farming. Background Technology

[0002] With the continuous development of animal husbandry, in order to ensure the quality and safety of livestock products, the testing level of various laboratories has been continuously improved, and serological testing methods such as agglutination test and tube agglutination test have been gradually introduced for the detection of swine pathogens.

[0003] However, in traditional testing procedures, subcutaneous sampling and sample storage are usually performed in two separate steps, which leads to cumbersome and inefficient sampling. During the sampling process, specialized equipment and personnel are required to operate the sample. At the same time, the sample needs to be transferred and stored after collection, which increases the complexity and time cost of the operation. In addition, the separation of sampling and storage steps may increase the risk of sample contamination, thereby affecting the accuracy of the test.

[0004] Therefore, in response to the existing test tubes for detecting pathogens in pig farming, which typically involve separate subcutaneous sampling and sample storage in two steps, resulting in cumbersome and inefficient sampling for detecting pathogens in pig farming, a new test tube for detecting pathogens in pig farming can be designed. Utility Model Content

[0005] To overcome the problem of cumbersome and inefficient sampling for swine pathogen detection, which is caused by the fact that subcutaneous sampling and sample storage are usually carried out in two separate steps.

[0006] The technical solution of this utility model is as follows: a test tube for detecting pathogens in pig farming, including a needle tube sleeve assembly, a vacuum threaded tube, and a sealing cap; the lower end of the needle tube sleeve assembly is provided with a vacuum threaded tube; a sealing cap is provided on one side of the needle tube sleeve assembly; the needle tube sleeve assembly includes a tube sleeve, a sampling needle, a lower row of needles, an elastic membrane tube, a fixed clamping block, a convex piston clamping block, a spring, a switch button, a transmission rod, and a needle tube reinforcing conical sleeve.

[0007] Preferably, after subcutaneous puncture of the pig through the sampling needle inside the tube sleeve, the vacuum negative pressure of the vacuum threaded tube is used to draw blood and other liquid samples from the tip of the sampling needle. Thus, sampling and storage can be completed in one subcutaneous puncture, which greatly improves the efficiency of subcutaneous sample collection for pig pathogen detection. This solves the problem of cumbersome and inefficient sampling for pig pathogen detection caused by the fact that existing pig pathogen detection test tubes usually separate subcutaneous sampling and sample storage into two steps.

[0008] Preferably, the upper end of the vacuum threaded tube test tube is provided with a tube sleeve, and the tube sleeve is threadedly sealed to the tube sleeve; a sampling needle is provided inside the tube sleeve; a needle tube reinforcing cone sleeve is provided outside the sampling needle, and the needle tube reinforcing cone sleeve is integrally formed with the tube sleeve, and the needle tube reinforcing cone sleeve is fixedly connected to the sampling needle.

[0009] Preferably, a lower row of needles is provided below the sampling needle, and the lower row of needles is fixedly connected to the inside of the tube sleeve; an elastic membrane tube is provided between the sampling needle and the lower row of needles, and the upper and lower ends of the elastic membrane tube are respectively connected to the sampling needle and the lower row of needles.

[0010] Preferably, a fixed clamping block and a convex piston clamping block are respectively provided on both sides of the elastic membrane tube, and the fixed clamping block is integrally formed with the tube sleeve, the convex piston clamping block is slidably arranged along the piston chamber inside the tube sleeve, and the membrane tubes on both sides of the elastic membrane tube are fixedly connected to the fixed clamping block and the convex piston clamping block respectively.

[0011] Preferably, a spring is provided at one end of the convex piston clamp, and the spring is located between the piston chamber of the sleeve and the convex piston clamp, and the spring is in a compressed state.

[0012] Preferably, a switch button is provided inside the front end of the sleeve, and the switch button is movably arranged along the internal groove of the sleeve; a transmission rod is provided around the rear end of the switch button, one end of the transmission rod is fixedly connected to the switch button, and the other end of the transmission rod passes through the fixed clamping block and is fixedly connected to the convex piston clamping block.

[0013] Preferably, the sealing cap is located on one side of the sleeve, and the sealing cap is connected to the outer shell of the sleeve via a bendable connecting rod, and the sealing cap and the sleeve are provided with an interference fit sealing connection.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing test tubes for swine pathogen detection typically involve separate subcutaneous sampling and sample storage, resulting in cumbersome and inefficient sampling processes. The new tube, however, allows for direct subcutaneous puncture of the pig using a sampling needle within the tube sleeve. The vacuum pressure within the vacuum-sealed tube then draws up blood and other liquid samples from the needle tip, enabling sampling and storage to be completed in a single subcutaneous puncture. This significantly improves the efficiency of subcutaneous sample collection for swine pathogen detection and solves the problem of cumbersome and inefficient sampling processes inherent in existing swine pathogen detection test tubes.

[0016] 2. Through the arrangement of the tubing, switch button, transmission rod, spring, convex piston clamp, fixed clamp, and elastic membrane tube, when the sampling needle is inserted subcutaneously into the pig, the spring is in a state where the convex piston clamp, along with the elastic membrane tube, is squeezed and blocked by the fixed clamp and convex piston clamp. At this time, the liquid sample at the tip of the sampling needle will not be forced into the vacuum threaded tube test tube by the negative pressure inside the vacuum threaded tube. During sampling, the thumb presses the switch button towards the fixed clamp, and the switch button, along with the transmission rod passing through the fixed clamp and the convex piston clamp connected thereto, moves towards the spring. At this point, the convex piston clamp moves towards the spring, causing the channel inside the elastic membrane tube to be stretched and expanded, thus connecting the channels of the sampling needle, elastic membrane tube, lower needle, and vacuum threaded tube. This allows samples such as pig blood to be squeezed into the vacuum threaded tube for collection. Releasing the switch button resets the spring and its connected convex piston clamp, closing the channel inside the elastic membrane tube. Finally, the sealing cap is placed on the tube sleeve and sealed, thus achieving simultaneous sampling and storage. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment: a test tube for detecting pathogens in pig farming, including a needle tube sleeve assembly 1, a vacuum threaded tube 2, and a sealing cap 3; the lower end of the needle tube sleeve assembly 1 is provided with the vacuum threaded tube 2; a sealing cap 3 is provided on one side of the needle tube sleeve assembly 1; the needle tube sleeve assembly 1 includes a tube sleeve 101, a sampling needle 102, a lower row of needles 103, an elastic membrane tube 104, a fixed clamping block 105, a convex piston clamping block 106, a spring 107, a switch button 108, a transmission rod 109, and a needle tube reinforcing conical sleeve 110.

[0024] Please see Figure 1-4 In this embodiment, a sleeve 101 is provided at the upper end of the vacuum threaded tube test tube 2, and the sleeve 101 is threadedly sealed to the tube sleeve 102; a sampling needle 102 is provided inside the sleeve 101; a needle tube reinforcing cone sleeve 110 is provided outside the sampling needle 102, and the needle tube reinforcing cone sleeve 110 is integrally formed with the sleeve 101, and the needle tube reinforcing cone sleeve 110 is fixedly connected to the sampling needle 102; a lower row of needles 103 is provided below the sampling needle 102. The lower row of needles 103 is fixedly connected to the inside of the sleeve 101; an elastic membrane tube 104 is provided between the sampling needle 102 and the lower row of needles 103, and the upper and lower ends of the elastic membrane tube 104 are respectively connected to the sampling needle 102 and the lower row of needles 103; a fixed clamping block 105 and a convex piston clamping block 106 are respectively provided on both sides of the elastic membrane tube 104, and the fixed clamping block 105 is integrally formed with the sleeve 101, and the convex piston clamping block 106 is piston-shaped inside the sleeve 101. The chamber is slidably arranged, and the two sides of the elastic membrane tube 104 are fixedly connected to the fixed clamping block 105 and the convex piston clamping block 106 respectively. A spring 107 is provided at one end of the convex piston clamping block 106, and the spring 107 is located between the piston chamber of the sleeve 101 and the convex piston clamping block 106, and the spring 107 is in a compressed state. A switch button 108 is provided inside the front end of the sleeve 101, and the switch button 108 is movably arranged along the internal sliding groove of the sleeve 101. A transmission rod 109 is provided around the rear end of the switch button 108, and one end of the transmission rod 109 is fixedly connected to the switch button 108, and the other end of the transmission rod 109 passes through the fixed clamping block 105 and is fixedly connected to the convex piston clamping block 106. A sealing cover 3 is provided on one side of the sleeve 101, and the sealing cover 3 is connected to the outer shell of the sleeve 101 through a bendable connecting rod, and the sealing cover 3 is press-fitted to the sleeve 101 for sealing.

[0025] During operation, when the sampling needle 102 is inserted under the skin of the pig, the spring 107 is in a state where the convex piston clamp 106 is pressed against the elastic membrane tube 104, which is squeezed and blocked by the fixed clamp 105 and the convex piston clamp 106. At this time, the liquid sample at the end of the sampling needle 102 will not be squeezed into the vacuum threaded tube 2 by the negative pressure inside the vacuum threaded tube test tube 2. When sampling, the thumb presses the switch button 108 towards the fixed clamp 105. The switch button 108, together with the transmission rod 109 passing through the fixed clamp 105 and the convex piston clamp 106 connected thereto, moves towards the spring 107. At this time, due to the convex piston clamp 106, the liquid sample at the end of the sampling needle 102 will not be squeezed into the vacuum threaded tube test tube 2 by the negative pressure inside the vacuum threaded tube test tube 2. Moving 06 towards spring 107 stretches and expands the channel inside elastic membrane tube 104, thereby connecting the channels of sampling needle 102, elastic membrane tube 104, lower row needle 103, and vacuum threaded tube 2. This allows samples such as pig blood to be squeezed into the vacuum threaded tube 2 for collection. Releasing the switch button 108 resets spring 107 and its connected convex piston clamp 106, thus closing the channel inside elastic membrane tube 104. Finally, the sealing cap 3 is placed on the tube sleeve 101 and sealed, thus achieving simultaneous sampling and storage. After the sampling needle 102 inside the tube sleeve 101 directly punctures the pig's skin, the vacuum negative pressure in the vacuum threaded tube 2 is used to draw blood and other liquid samples from the end of the sampling needle 102. Thus, sampling and storage can be completed in one subcutaneous puncture, which greatly improves the efficiency of subcutaneous sample collection for pig pathogen detection. This solves the problem of cumbersome and inefficient sampling for pig pathogen detection caused by the existing pig farming pathogen detection test tubes, which usually separate subcutaneous sampling and sample storage into two steps.

[0026] Through the above steps, after directly puncturing the pig subcutaneously with the sampling needle 102 inside the tube sleeve 101, the blood and other liquid samples from the end of the sampling needle 102 are drawn using the vacuum negative pressure in the vacuum threaded tube 2. Thus, sampling and storage can be completed in one subcutaneous puncture, which greatly improves the efficiency of subcutaneous sample collection for pig pathogen detection. This avoids the problem of cumbersome and inefficient sampling for pig pathogen detection caused by existing pig farming pathogen detection test tubes, which usually separate subcutaneous sampling and sample storage into two steps.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
