Description

Technical Field

[0001] The invention belongs to the technical field of medical sampling, and in particular relates to a sample collection device applied to animal husbandry and veterinary epidemic diseases. Background Art

[0002] Animal husbandry is a production sector that utilizes the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, through artificial breeding and reproduction, to transform plant energy such as forage and feed into animal energy, in order to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials. For the health monitoring of certain livestock, blood samples will be taken for laboratory analysis.

[0003] When conducting disease detection on livestock farms, it is necessary to collect blood samples from livestock and conduct biochemical analysis on the blood samples. Currently, when collecting blood samples, it mainly relies on staff to hold syringes and use the syringes to draw blood from the livestock's bodies. The drawn blood is then injected into a sampling tube. The staff then transfers the sampling tubes containing the blood samples to the testing center, which then tests and analyzes the blood samples in the sampling tubes.

[0004] However, the applicant discovered in actual operation that since the syringe is a disposable consumable, that is, a syringe can only be used once, after collecting a sample, the staff needs to replace the next syringe to extract and collect the blood sample, and the blood sample in the syringe needs to be collected into the sampling tube in time. When a single staff member collects the sample, due to failure to inject the blood sample collected in the syringe into the sampling tube in time, and then replace the next syringe to collect the blood sample, when the blood sample in the syringe is subsequently injected into the sampling tube, the sampling tube number corresponding to the syringe may be forgotten, resulting in confusion between the sampling tube number and the livestock number, which affects the accuracy of sample collection;

[0005] In addition, since a single staff member needs to use a syringe to draw blood samples when collecting samples, and then inject the blood samples into numbered sampling tubes after drawing, the operating efficiency of a single staff member is low, and thus the efficiency of sample collection is also low. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a sample collection device for animal husbandry and veterinary epidemic diseases.

[0007] The technical solution adopted to solve the above technical problems is: a sample collection device applied to animal husbandry and veterinary diseases, comprising a gun-type seat, wherein a recessed installation cavity is provided on the top of the gun-type seat;

[0008] A slider horizontally slidably connected to the installation cavity, a syringe installation box is horizontally fixed to the top of the slider through a connecting column, and a syringe is clamped and installed in the syringe installation box;

[0009] A rotating plate rotatably connected to the front end of the gun-type seat, wherein one end of the rotating plate is provided with a notch groove for the needle of the syringe to freely pass through;

[0010] A sampling tube mounting seat is rotatably connected to the other end of the rotating plate, and a plurality of sampling tube mounting grooves are provided on the end surface of the sampling tube mounting seat. Sampling tubes with plugs are tightly inserted into the sampling tube mounting grooves.

[0011] Through the above technical scheme, the syringe is placed in the syringe mounting box and fixed, and the slider slides in the mounting cavity to realize sample collection of the syringe. In addition, after the syringe is collected, the syringe retreats and then rotates 180° through the rotating plate, so that the mounting seat of the stoppered sampling tube is rotated to correspond to the syringe, and the syringe then moves in the direction of the rotating plate, so that the needle of the syringe penetrates into one of the stoppered sampling tubes, and the syringe injects the blood sample collected inside into the stoppered sampling tube, thereby realizing rapid collection of samples into the stoppered sampling tube after sample collection, reducing the phenomenon of label confusion and improving sample collection efficiency.

[0012] Furthermore, a needle avoidance opening and a piston rod avoidance opening are respectively provided at two ends of the syringe installation box, and a handle bayonet is also provided at one end of the syringe installation box corresponding to the piston rod avoidance opening.

[0013] Through the above technical solution, the needle of the syringe can pass through the needle avoidance port, the barrel of the syringe is clamped and placed in the cavity of the syringe mounting box, the piston rod of the syringe can freely pass through the piston rod avoidance port, and the handle of the syringe is clamped in the handle clamping port, thereby clamping the syringe in the syringe mounting box.

[0014] Furthermore, a mounting block is fixedly connected to the bottom of the syringe mounting box, and a liquid pushing cylinder is horizontally mounted on the side wall of the mounting block. The cylinder rod of the liquid pushing cylinder penetrates the mounting block and slides freely. The end of the cylinder rod of the liquid pushing cylinder is fixedly connected to the liquid pushing block, and the liquid pushing block is provided with a pressing plate snap-in.

[0015] Through the above technical solution, the cylinder rod of the liquid pushing cylinder is extended and retracted, thereby driving the liquid pushing block to move, and the liquid pushing block drives the pressing plate of the syringe to move, so that the syringe can perform blood extraction.

[0016] Furthermore, a guide rod is penetrated through the outer wall of the gun-type seat, and the sliding block is provided with a guide hole for the guide rod to freely pass through.

[0017] Through the above technical solution, the guide rod slides in the guide hole, so that the slider is guided and limited when sliding in the installation cavity.

[0018] Furthermore, an electromagnet is fixedly connected to the inner wall of one side of the installation cavity adjacent to the rotating plate, and the electromagnet forms a magnetic fit with the slider. A tension spring is wrapped around the periphery of the guide rod, and both ends of the tension spring are respectively fixed to the slider surface and the inner wall of the installation cavity.

[0019] Through the above technical solution, the electromagnet is energized to generate magnetism, which in turn generates a magnetic attraction force on the slider, so that the slider drives the syringe to move, and the needle of the syringe can be pierced into the body of the livestock. The tension spring can drive the slider to move in the opposite direction after the electromagnet is powered off, so that the needle of the syringe can be pulled out of the body of the livestock.

[0020] Furthermore, a rotating shaft is horizontally penetrated through the front end portion of the gun-type seat, the rotating shaft is rotatably connected to the gun-type seat, the rotating plate is rotatably fixedly connected to the end of the rotating shaft passing through the gun-type seat, the end of the rotating shaft passing through the gun-type seat is coaxially sleeved with a worm gear, a rotating rod is horizontally penetrated through the side wall of the gun-type seat, the rotating rod is rotatably connected to the gun-type seat, a worm portion meshing with the worm gear is provided at the periphery of the rotating rod, and an equal-angle rotating unit is provided on the gun-type seat, and the equal-angle rotating unit is used to drive the rotating shaft to rotate a fixed angle when the slider moves in a direction away from the rotating plate.

[0021] Through the above technical solution, when the slider moves in a direction away from the rotating plate, it will drive the rotating shaft to rotate a certain angle, thereby causing the rotating plate to rotate 180°.

[0022] Furthermore, the equal-angle rotation unit includes a fixing ring fixedly sleeved on the end of the rotating rod, a gear is coaxially sleeved on the periphery of the fixing ring, a rotating hole for the fixing ring to engage is coaxially opened on the end face of the gear, the fixing ring periphery rotates freely in the rotating hole, an elastic baffle is fixedly connected to the periphery of the fixing ring, a receiving groove is opened on the periphery of the fixing ring for the elastic baffle to pass freely, a accommodating cavity used in cooperation with the elastic baffle is opened on the rotating hole wall of the gear, and a rotating assembly is provided on the slider, and the rotating assembly is used to drive the gear to rotate.

[0023] Through the above technical solution, when the gear rotates, if the elastic baffle slides along the inclined surface of the accommodating cavity, the rotation of the gear will not be able to drive the fixed ring to rotate, and will not drive the rotating shaft to rotate. On the contrary, when the end of the elastic baffle away from the fixed ring is against the straight surface of the accommodating cavity, the rotation of the gear will drive the fixed ring to rotate, so that the rotating shaft and the gear rotate synchronously.

[0024] Furthermore, a blocking bar is fixedly connected to the end surface of the rotating rod, and the surface of the blocking bar is in sliding contact with the end surface of the gear.

[0027] Through the above technical solution, when the driving plate moves toward the rotating plate, the gear part on the driving plate meshes with the gear, the elastic baffle slides on the hole wall of the rotating hole and the inclined surface of the accommodating cavity, and the elastic baffle generates elastic bending toward the radial inner side of the rotating rod, so that the elastic baffle is squeezed by the inclined surface of the rotating hole wall and the rotating hole wall and is bent and received in the receiving groove, the periphery of the fixed ring and the rotating hole of the gear, and when the driving plate moves in the reverse direction, the gear will rotate in the reverse direction, and the end of the elastic baffle away from the fixed ring will abut against the straight surface of the accommodating cavity, so that the fixed ring and the gear can be relatively still, so that when the gear rotates, the fixed ring is synchronously driven to rotate.

[0028] Furthermore, a fixing sleeve is fixedly connected to the front end of the gun-type seat, the rotating shaft coaxially penetrates the fixing sleeve and rotates freely, the periphery of the sampling tube mounting seat is fixedly sleeved with an annular rack, and the periphery of the fixing sleeve is provided with an annular gear segment meshing with the annular rack.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) In the present invention, the syringe is placed in the syringe mounting box and fixed, and the slider slides in the mounting cavity to realize sample collection of the syringe. In addition, after the syringe has completed the sample collection, the syringe retreats and then rotates 180° through the rotating plate, so that the stoppered sampling tube mounting seat is rotated to correspond to the syringe. The syringe then moves in the direction of the rotating plate, so that the needle of the syringe penetrates into one of the stoppered sampling tubes, and the syringe injects the blood sample collected inside into the stoppered sampling tube, thereby realizing that after the sample is collected, the sample is quickly collected into the stoppered sampling tube, reducing the phenomenon of label confusion and improving the sample collection efficiency;

[0032] (2) In the present invention, the electromagnet generates magnetism when it is energized, thereby generating a magnetic attraction force on the slider, so that the slider drives the syringe to move, and the syringe needle can be inserted into the body of the livestock. After the electromagnet is powered off, the tension spring can drive the slider to move in the opposite direction, so that the syringe needle can be pulled out of the body of the livestock.

[0033] (3) In the present invention, when the driving plate moves toward the rotating plate, the gear part on the driving plate meshes with the gear, the elastic baffle slides on the hole wall of the rotating hole and the inclined surface of the accommodating cavity, and the elastic baffle generates elastic bending toward the radial inner side of the rotating rod, so that the elastic baffle is squeezed by the inclined surface of the rotating hole wall and the rotating hole wall and is bent and accommodated in the accommodation groove, the periphery of the fixed ring and the rotating hole of the gear. When the driving plate moves in the reverse direction, the gear will rotate in the reverse direction, and the end of the elastic baffle away from the fixed ring will abut against the straight surface of the accommodating cavity, so that the fixed ring and the gear can be relatively still, so that when the gear rotates, the fixed ring is synchronously driven to rotate.

The bottom surface of the avoidance section 25 is located above the gear 4, so that the gear 4 will not contact the bottom surface of the avoidance section 25. A baffle 30 is fixedly connected to the end surface of the rotating rod 26, and the surface of the baffle 30 is in sliding contact with the end surface of the gear 4. The end surface of the gear 4 is limited by the baffle 30, so that the gear 4 can rotate on the fixed ring 32 and will not separate from the periphery of the fixed ring 32. A fixed sleeve 19 is fixedly connected to the front end of the gun-type seat 14, and the rotating shaft 22 coaxially penetrates the fixed sleeve 19 and rotates freely. The periphery of the sampling tube mounting seat 3 is fixedly sleeved with an annular rack 2, and the periphery of the fixed sleeve 19 is provided with an annular gear section 20 meshing with the annular rack 2.

[0050] The working principle of this embodiment is as follows:

[0051] Clamping the syringe 9: unpack the disposable syringe 9, and then put it into the syringe installation box 10, the needle of the syringe 9 passes through the needle avoidance port, the handle of the syringe 9 is engaged in the handle bayonet 11, the piston rod of the syringe 9 passes through the piston rod avoidance port, and the pressing plate of the syringe 9 is engaged in the pressing plate bayonet 13 of the liquid pusher 12. At this time, the syringe 9 will be completely limited in the syringe installation box 10, and the syringe 9 is in a lateral limit state. At this time, the electromagnet 23 is in a power-off state, so that the magnetic attraction of the electromagnet 23 to the slider 16 disappears, and the tension spring 21 has a pulling force on the slider 16, so that the slider 16 moves in the direction away from the electromagnet 23;

[0052] Blood collection: The staff holds the handle of the gun-type seat 14, and places the side of the rotating plate 7 facing away from the syringe 9 against the surface of the livestock, and aligns the notch 8 with the vein position of the livestock. A button switch is set on the handle, and the button switch is used to control the power on and off of the electromagnet 23. The staff presses the button switch, and the button switch is in the on state, so that the power of the electromagnet 23 is turned on, and then the electromagnet 23 is in the energized state, and the electromagnet 23 generates magnetism and generates magnetic attraction to the slider 16, so that the slider 16 moves toward the direction of the rotating plate 7, and the tension spring 21 is in the The slider 16 is in a stretched state and accumulates elastic potential energy. During the movement, the slider 16 will synchronously drive the syringe mounting box 10 to move toward the surface of the livestock, so that the needle of the syringe 9 pierces the vein in the livestock. At the same time, the liquid pushing cylinder 15 is started, and the cylinder rod of the liquid pushing cylinder 15 is extended, and drives the liquid pushing block 12 to move away from the syringe mounting box 10, so that the piston rod of the syringe 9 drives the piston of the syringe 9 to move, so that the inside of the syringe 9 is in a low pressure state, so that the venous blood of the livestock can flow from the needle into the syringe 9 to achieve blood collection;

[0053] In addition, when the slider 16 moves toward the rotating plate 7, Figure 7 , which will cause the driving plate 5 to move toward the rotating plate 7, and cause the gear portion 28 of the driving plate 5 to mesh with the gear 4. When meshing, the gear 4 will rotate, and at this time, the end of the elastic baffle 35 away from the fixed ring 32 will slide on the inclined surface of the accommodating cavity 36 and the rotating hole wall of the gear 4, and because the surface of the rotating plate 7 is against the body surface of the livestock, there is friction between the rotating plate 7 and the body surface of the livestock. When the surface of the elastic baffle 35 contacts the rotating hole wall, the elastic baffle 35 will bend elastically and enter the receiving groove 37, so that the rotation of the gear 4 will not drive the fixed ring 32 to rotate, so that the rotating rod 26 will not rotate. During the movement of the syringe 9, the gear 4 will gradually break away from the state of meshing with the gear portion 28, and the gear 4 will move to the bottom of the avoidance section 25, and the gear 4 will not continue to rotate at this time;

[0054] Sample injection: After the blood sample is collected, the staff quickly moves the gun holder 14 away from the livestock's body surface to pull the needle of the syringe 9 out of the livestock's body, and then disconnects the power supply of the electromagnet 23. At this time, the elastic potential energy accumulated in the tension spring 21 is released, causing the slider 16 to move away from the rotating plate 7. During the movement, the drive plate 5 will move in the opposite direction. In the initial stage of the movement, the gear 4 is located below the avoidance section 25, causing the drive plate 5 to move, and the gear 4 will not engage with the gear portion 28, that is, the needle of the syringe 9 has time to move away from the notch groove 8 on the rotating plate 7 to prevent the inner wall of the notch groove 8 from contacting the needle. When the gear 4 begins to engage with the gear portion 28, the needle of the syringe 9 has already moved away from the rotating plate 7, and the gear 4 will rotate, causing the end of the elastic baffle 35 away from the fixed ring 32 to contact the straight surface (vertical inner wall) of the accommodating cavity 36, so that the fixed ring 32 will be relatively stationary with the gear 4, that is, the gear 4 begins to engage with the gear portion 28. When the wheel 4 rotates, it will drive the fixed ring 32 to rotate. When the fixed ring 32 rotates, it will drive the rotating rod 26 to rotate, so that the worm part 27 and the worm wheel 33 are meshed and rotated, and the rotating shaft 22 is driven to rotate. When the rotating shaft 22 rotates, it will drive the rotating plate 7 to start rotating. After the syringe mounting box 10 retreats to its proper position, the rotating plate 7 rotates to 180°. When the rotating plate 7 rotates, it will drive the sampling tube mounting seat 3 to rotate around the axial direction of the rotating shaft 22, so that the annular rack 2 and the annular gear segment 20 are meshed and rotated, so that the sampling tube mounting seat 3 rotates around itself at the same time, so that when the rotating plate 7 rotates to its proper position, one of the sampling tubes 1 with a stopper rotates to a state that is substantially coaxial with the needle of the syringe 9, and then the button switch is pressed again, so that the electromagnet 23 is in an energized state, and then the slider 16 drives the syringe 9 to move toward the direction of the rotating plate 7 again, so that the needle of the syringe 9 penetrates the rubber stopper of the sampling tube 1 with a stopper;

[0055] Then, when the syringe mounting box 10 moves into place, the needle penetrates into the inside of the plugged sampling tube 1, and then the liquid pushing cylinder 15 is started again, the cylinder rod of the liquid pushing cylinder 15 is shortened, and the liquid pushing block 12 is driven to move in the direction of the syringe mounting box 10, so that the liquid pushing block 12 pushes the piston in the syringe 9 to move, and the blood sample in the syringe 9 is injected into the plugged sampling tube 1. After the injection is completed, the power supply of the electromagnet 23 is disconnected again, and the tension spring 21 pulls the slider 16 to move in the opposite direction, so that the needle of the syringe 9 is first pulled out of the plugged sampling tube 1, and then the gear 4 is The rotating plate 7 begins to mesh with the gear portion 28, so that the rotating plate 7 rotates 180° again, so that the notch 8 of the rotating plate 7 rotates to correspond to the syringe 9. In this embodiment, the rotating plate 7 rotates 360°, that is, after the rotating plate 7 rotates a full circle, the sampling tube 1 with a stopper can alternately correspond to the syringe 9, or in other words, when the rotating plate 7 rotates a circle, the next sampling tube 1 with a stopper can be rotated to correspond to the syringe 9, and then the staff takes the syringe 9 out of the syringe installation box 10 and replaces it with a new syringe 9 to carry out the next blood collection work;

[0056] In addition, further, in this embodiment, a hollow rubber sleeve 29 is installed at the end of the gun-type seat 14, and a marking rubber sleeve 39 is integrally formed at one end of the hollow rubber sleeve 29 facing the downward rotating plate 7. The outer diameter of the marking rubber sleeve 39 is not greater than the inner diameter of the sampling tube 1 with a plug. A storage cavity 41 for storing a marking liquid is provided inside the hollow rubber sleeve 29 and the marking rubber sleeve 39. A notch 38 for the needle of the syringe 9 to pass freely is provided on the periphery of the marking rubber sleeve 39 and the hollow rubber sleeve 29.
