[0017] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed below.
[0018] As Figures 1-10 The utility model discloses a kind of veterinary gene screening collectors, including collection mechanism 1 and positioning mechanism 2, collection mechanism 1 includes test tube 27, the opening of the top of test tube 27 is installed with sealing cover 30, the middle part of sealing cover 30 is provided with rubber sheet 31, positioning mechanism 2 includes base 4, one side of the top of base 4 is fixedly installed with vertical plate 5, one end of the top of vertical plate 5 and in the directly above of base 4 movably set with extrusion plate 6, a cavity is arranged between base 4, extrusion plate 6 and vertical plate 5, test tube 27 is in the cavity, the inside of vertical plate 5 is provided with movable assembly, movable assembly is used to control extrusion plate 6, the inside of extrusion plate 6 is provided with needle 21, the bottom of test tube 27 is opened with through slot, the inside of test tube 27 movably is provided with sealing ring 32, sealing ring 32 is fixedly connected with connecting ring 33, the bottom of connecting ring 33 is provided with clamping assembly, the surface of base 4 is provided with drive mechanism 3, drive mechanism 3 includes push-pull rod 22, push-pull rod 22 movably penetrates base 4, the top of push-pull rod 22 is fixedly installed with clamping disc 26, the top of push-pull rod 22 is movably inserted in the inside of test tube 27 by through slot, and clamping disc 26 is matched with clamping assembly, by the cooperation between collection mechanism 1, positioning mechanism 2 and drive mechanism 3, test tube 27 can be closed all the way, needle 21 punctures directly infusion blood, and prevent sample contamination and operator infection risk, while realizing the convenient operation of sample collection, test tube 27 fixation and disassembly, needle 21 positioning and replacement etc.
[0019] The clamping assembly comprises a connecting groove 34, which is arranged at the middle end of the bottom of the connecting ring 33. Two recovery grooves 35 are symmetrically arranged at the end of the opening of the connecting groove 34. A second spring 36 is arranged in the recovery groove 35. A limiting block 37 is arranged at the end of the second spring 36 and is slidingly arranged in the recovery groove 35. The end of the limiting block 37 close to the middle of the connecting groove 34 is arranged as an arc surface. A slant groove is arranged on the surface of the limiting block 37. An extrusion ring 38 is arranged at the bottom of the inner cavity of the test tube 27. The top end of the extrusion ring 38 is arranged as a slant block matched with the slant groove. When the push-pull rod 22 is pushed, the clamping disc 26 moves upward from the penetrating groove at the bottom of the test tube 27 and is inserted into the connecting groove 34. At this time, the edge of the clamping disc 26 extrudes the arc surface of the limiting block 37, so that the limiting block 37 slides into the recovery groove 35 against the elastic force of the second spring 36, thereby facilitating the smooth entry of the clamping disc 26 into the connecting groove 34. When the clamping disc 26 is completely inserted into the connecting groove 34, the limiting block 37 is popped out under the action of the second spring 36. The edge of the clamping disc 26 is clamped by the limiting block 37, thereby realizing the fixation of the clamping disc 26 and the connecting groove 34. Thus, the push-pull rod 22 can drive the sealing ring 32 to move upward or downward in the test tube 27. When the sealing ring 32 drives the connecting ring 33 to move downward, the slant groove of the limiting block 37 contacts the slant block at the top end of the extrusion ring 38 at the bottom of the test tube 27. The slant block slides along the slant groove, forcing the limiting block 37 to shrink into the recovery groove 35 and releasing the limitation on the clamping disc 26. At this time, the clamping disc 26 can be separated from the connecting groove 34, and the push-pull rod 22 can be completely taken out of the test tube 27.
[0020] An input port 39 is arranged at the bottom of the rubber sheet 31 and in the test tube 27. The input port 39 is arranged as a taper. A rubber strip 40 is arranged at the end of the input port 39. The rubber strip 40 is arranged as a spiral. The bottom end of the rubber strip 40 is connected to the sealing ring 32. The taper design of the input port 39 can guide the sample to flow downward along the inner wall, avoiding the sample remaining at the top of the test tube 27. The spiral rubber strip 40 can generate a turbulence effect when the sample flows, so that the sample is more uniformly distributed in the test tube 27. At the same time, the adsorption of the spiral structure can assist the sample to be transported downward, reducing the residue.
[0021] A disc 23 is fixedly arranged on the upper surface of the base 4. A receiving groove 24 is arranged at the middle end of the disc 23. Two limiting grooves 25 are symmetrically arranged on the surface of the disc 23. A connecting disc 28 is arranged at the end surface of the bottom of the test tube 27. Two limiting strips 29 are symmetrically arranged at the bottom of the connecting disc 28. The two limiting strips 29 are matched with the two limiting grooves 25, respectively. The limiting strips 29 on the connecting disc 28 at the bottom of the test tube 27 are inserted into the limiting grooves 25 of the disc 23 on the base 4. At this time, the limiting strips 29 and the limiting grooves 25 form a clamping connection, thereby fixing the test tube 27 in the cavity. The receiving groove 24 is located at the middle of the disc 23. The top end of the push-pull rod 22 ensures that the push-pull rod 22 moves up and down without being hindered. At the same time, the receiving groove 24 provides a space for the cooperation of the clamping disc 26 and the clamping assembly.
[0022] The surface of the extrusion plate 6 is provided with a rectangular groove 18, and the upper and lower ends of the middle part of the rectangular groove 18 are provided with vertical grooves 19. The rectangular groove 18 and the vertical groove 19 are combined into a cross groove. The needle 21 is fixedly installed on the surface close to the bottom, the clamping plate 20 is movably inserted into the rectangular groove 18, the needle 21 is in the vertical groove 19, and the clamping plate 20 needs to be inserted from the side of the rectangular groove 18 of the extrusion plate 6. The needle 21 passes through the vertical groove 19, and the clamping plate 20 can slide in the horizontal direction in the rectangular groove 18, but is limited by the width of the vertical groove 19, and the needle 21 cannot deviate left and right, so as to ensure that the needle 21 is vertically aligned with the rubber sheet 31 and the input port 39 at the top of the test tube 27.
[0023] The surface of the vertical plate 5 is provided with a groove 7, and the movable assembly comprises a protruding plate 11 movably installed in the groove 7. The inside of the groove 7 is provided with a guide column 9, the surface of the guide column 9 is provided with a first spring 10, the protruding plate 11 is movably sleeved on the surface of the guide column 9, and the first spring 10 is above the protruding plate 11. The inside of the vertical plate 5 is provided with a through groove 8, the end of the protruding plate 11 is fixedly provided with an L-shaped connecting column 12, the surface of the L-shaped connecting column 12 is movably arranged in the through groove 8, and the top end of the L-shaped connecting column 12 is fixedly connected with the extrusion plate 6. When the protruding plate 11 is pushed upward by external force, it drives the extrusion plate 6 to slide upward through the L-shaped connecting column 12. The guide column 9 penetrates the protruding plate 11 to limit its left and right deviation, so as to ensure the vertical movement of the extrusion plate 6. At this time, the protruding plate 11 compresses the first spring 10 above it. At this time, the L-shaped connecting column 12 will drive the extrusion plate 6 to rise synchronously, so that the bottom of the needle 21 can be separated from the rubber sheet 31, facilitating the replacement of the needle 21. At the same time, the extrusion plate 6 is lifted upward, the space of the cavity is increased, and the test tube 27 can also be easily taken out by the worker.
[0024] The surface of the L-shaped connecting column 12 is provided with a movable groove 13, the inner wall of the movable groove 13 is provided with a path groove 14, the path groove 14 comprises a straight groove and an inclined groove, the inclined groove is connected at the bottom end of the straight groove, the inside of the movable groove 13 is movably provided with a pushing column 15, the side surface of the pushing column 15 is fixedly provided with a sliding column 16, the surface of the sliding column 16 is movably arranged in the path groove 14, and the inside of the cavity is provided with an arc-shaped plate 17. The end of the pushing column 15 movably penetrates the vertical plate 5 to connect the arc-shaped plate 17. When the L-shaped connecting column 12 moves up and down with the extrusion plate 6, the sliding column 16 in the movable groove 13 moves along the path groove 14. When the L-shaped connecting column 12 moves upward, the sliding column 16 first slides along the straight groove, and the position of the pushing column 15 does not change. When the sliding column 16 reaches the bottom end of the straight groove, it enters the inclined groove track. At this time, it will push the pushing column 15 to move horizontally to the center of the cavity, drive the arc-shaped plate 17 to extrude the outer wall of the test tube 27, so as to push the test tube 27 to the outside of the cavity, facilitating the worker to disassemble the test tube 27.
[0025] The bottom of the needle 21 can pierce the rubber sheet 31, and the needle tip of the needle 21 is designed as a sharp inclined surface. When the pressing plate 6 drives the needle 21 to move downward, the needle tip generates concentrated pressure on the rubber sheet 31. When the concentrated pressure exceeds the puncture resistance of the rubber sheet 31, the needle tip pierces into the rubber sheet 31 and forms a puncture hole. The elastic material of the rubber sheet 31 deforms when the needle 21 pierces into it, wraps the outer wall of the needle 21, and forms a preliminary seal. After the needle 21 is pulled out, the rubber sheet 31 elastically contracts, the puncture hole is closed, and automatic plugging is achieved.
[0026] Working principle: First, the staff pushes the convex plate 11 upwards, lifting the extrusion plate 6 to a certain position, at this time the distance between the extrusion plate 6 and the test tube 27 is slightly greater than the distance from the bottom of the needle 21 to the locking plate 20, and the arc-shaped plate 17 does not move, then the limiting strip 29 on the connecting disc 28 at the bottom of the test tube 27 is inserted into the limiting groove 25 of the disc 23 on the base 4, the limiting strip 29 and the limiting groove 25 are clamped, so that the test tube 27 is fixed in the cavity between the base 4 and the extrusion plate 6, then the locking plate 20 is inserted from the side of the rectangular groove 18 of the extrusion plate 6, so that the needle 21 passes through the vertical slot 19, the needle 21 is vertically aligned with the rubber sheet 31 at the top of the test tube 27 and the input port 39, the upward pushing force is released, the convex plate 11 returns to its original position, the needle tip at the bottom of the needle 21 exerts concentrated pressure on the rubber sheet 31, and when the pressure exceeds the puncture resistance of the rubber sheet 31, the needle tip at the bottom of the needle 21 pierces into and forms a puncture hole, at this time the needle tip at the bottom of the needle 21 is in the input port 39, the next step is to push the push-pull rod 22, so that the clamping disc 26 at the top of the push-pull rod 22 moves upwards from the through groove at the bottom of the test tube 27, the edge of the clamping disc 26 extrudes the arc surface of the limiting block 37, and the limiting block 37 slides back into the recovery groove 35 against the elastic force of the second spring 36, after the clamping disc 26 is completely inserted, the limiting block 37 is ejected under the action of the second spring 36 to clamp the edge of the clamping disc 26, achieving the fixed connection between the push-pull rod 22 and the connecting ring 33, then the sealing ring 32 is pushed to the top of the test tube 27 by the push-pull rod 22, and the air inside the test tube 27 is discharged, then the top of the needle 21 is inserted into the blood vessel of the animal, and the push-pull rod 22 is slowly pulled, at this time the blood of the animal is injected into the test tube 27 through the needle 21, the sample flows downward along the conical inner wall of the input port 39, and the spiral rubber strip 40 generates a turbulence effect, so that the sample is uniformly distributed in the test tube 27, and the adsorption of the spiral structure reduces sample residue, when the connecting ring 33 and the sealing ring 32 move downwards to the bottom of the test tube 27 under the action of the push-pull rod 22, the inclined groove of the limiting block 37 contacts with the inclined block at the top of the extrusion ring 38, the inclined block slides along the inclined groove, forcing the limiting block 37 to retract into the recovery groove 35, and the limiting of the clamping disc 26 is released, at this time the push-pull rod 22 can be taken out of the test tube 27, the sealing ring 32 remains in the test tube 27, the sample is sealed, and the clamping disc 26 at the top of the push-pull rod 22 is stored in the storage groove 24, finally, the extrusion plate 6 is pushed upwards, the L-shaped connecting column 12 drives the needle 21 to move upwards, the needle 21 is extracted from the rubber sheet 31, the rubber sheet 31 is retracted due to elasticity, the puncture hole is closed, preventing sample leakage or contamination, the extrusion plate 6 is continuously pushed upwards, the L-shaped connecting column 12 moves upwards, the sliding column 16 in the movable slot 13 first slides along the straight slot of the path slot 14, at this time the pushing column 15 remains in place, when the sliding column 16 reaches the bottom end of the straight slot and enters the inclined slot, the pushing column 15 moves horizontally to the center of the cavity, driving the arc-shaped plate 17 to extrude the outer wall of the test tube 27, the test tube 27 is pushed out of the cavity, the staff holds the test tube 27,The limiting strip 29 is pulled out of the limiting slot 25, the disassembly of the test tube 27 is completed, the pressing plate 6 is loosened, the first spring 10 is reset, the convex plate 11 and the L-shaped connecting column 12 are driven to slide downward, the pressing plate 6 falls back to the initial position, the sliding column 16 moves reversely along the path slot 14, the arc-shaped plate 17 is reset, the needle 21 is disassembled by pulling out the clamping plate 20, and the next use is waited.
