Description

Technical Field

[0001] The utility model relates to the technical field of animal tissue sample sampling, in particular to an insertable and easy-to-align pig tonsil sampler. Background Art

[0002] Pig tonsils are a pair of flat oval lymphoid organs located in the tonsillar fossa, at the junction of the digestive tract and respiratory tract. They can be collected from the root of the tongue, the anterior pharyngeal wall, and the posterior pharyngeal wall.

[0003] The existing method of collecting pig tonsils is to manually control a steel tube with a bayonet at one end to obtain a small piece of tonsil tissue by clamping in the pig's pharynx. The amount of sample obtained at one time is small. In order to achieve the amount of experimental detection, it is often necessary to insert the steel tube into the pig's pharynx for sampling many times. The sampling process takes a long time and the pig's stress response is large. At this time, it is more difficult to align the sampler with the pig's tonsil position. In order to extend the sampling time, it is easy to cause serious damage to the pig's pharynx and oral cavity. If the care is not done properly in the later stage, it is easy to be infected with bacteria and cause the pig to become ill. In addition, two large barrels are prepared for sampling, and there are many sampling instruments to carry. After collecting the tonsil samples of a pig, the samples need to be scraped off, soaked in disinfected water, and then washed in clean water before collecting the next pig. The samples remaining in the sampling bayonet will cause cross contamination and affect the test results. Based on the above problems, this application is specially proposed to solve these problems.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0022] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.

[0023] like Figure 1 and Figure 2 As shown, the utility model relates to an insertable and easy-to-align pig tonsil sampler, the sampler comprises: a gun-shaped hand piece 1 for holding by hand, a starting trigger 5, and a core material 2 and a sleeve 3 both in the form of long strips, the sleeve 3 is sleeved on the outer periphery of the core material 2, and is installed on the gun-shaped hand piece 1 together with the core material 2, a sampling gun head with a length is formed on the gun-shaped hand piece 1, and the starting trigger 5 is connected to the sleeve 3 and / or the core material 2.

[0024] The gun-shaped handpiece 1 includes a handpiece and a through hole 11 arranged above the handpiece, the through hole 11 is arranged at a position corresponding to the gun rod, the core material 2 and the sleeve 3 are coaxially arranged, and the core material 2 passes through the through hole 11 and is connected to the gun-shaped handpiece 1. In addition, since the sampler of the present application is for sampling tonsils of living pigs, during the sampling process, the pig's nose is firstly covered with a lasso, and the end of the lasso is fixed at a required position, and then the mouth of the pig is opened to a specific extent with an opener. At this time, it can be ensured that the pig's head will not shake violently, and the sampling personnel can use the sampling gun from the outside to The head is against the position of the tonsil for sampling. In addition, the core material 2 and the sleeve 3 are in the shape of long strips, that is, the length of the core material 2 and the sleeve 3 is further limited, that is, the length of the core material 2 and the sleeve 3 should not be too short, so as to avoid the sampler's hand reaching into the pig's mouth during the sampling process, causing potential safety hazards. In this application, the length of the core material 2 is at least three times the length of the handpiece 1 itself. In this way, it can be ensured that the handpiece 1 is always operated outside the pig's mouth during the sampling process, which is easy to operate, and can also make the sampler adapt to pigs of different sizes, thereby improving the applicability of the sampler.

[0025] For the convenience of description, during the sampling process, the direction in which the gun tip extends out of the handpiece 1 is recorded as the front, and correspondingly, the opposite direction of the gun tip is recorded as the rear of the barrel. At this time, the core material 2 is located above the handpiece 1, and correspondingly, the starting trigger 5 is located below the core material 2.

[0026] Specifically, the rear end of the core material 2 passes through the through hole 11 of the gun-shaped handpiece 1 and is connected to the other side of the handpiece 1, which is recorded as the connecting end 21. The sampling end extending forward along the position of the gun barrel is recorded as the extending end 22. Correspondingly, the sleeve 3 has an abutting end 31 and a matching end 32. The matching end 32 of the sleeve 3 is close to the extending end 22, and a starting trigger 5 is installed in the middle area of ​​the gun-shaped handpiece 1. The upper part of the starting trigger 5 is a pushing end, which is movably connected to the handpiece 1. The coil spring 51 is located at the abutting end 31 of the sleeve 3 and is fixedly connected to the pushing end of the upper part of the starting trigger 5. At this time, the length direction of the coil spring 51 is consistent with the length direction of the core material 2; the lower part of the starting trigger 5 is the pulling end. When the pulling end of the starting trigger 5 is pulled backward, the corresponding pushing end of the upper part of the starting trigger 5 will move forward and compress the coil spring 51 forward. The coil spring 51 will produce a spiral motion along the spiral direction during the compression process. The torque acts on the contact position between the starting trigger 5 and the sleeve 3 to generate a friction force that causes it to rotate, and after the coil spring 51 is compressed, it will generate an elastic restoring force in the axial direction. At this time, the coil spring 51 drives the sleeve 3 to extend forward and rotate in the circumferential direction. The compressed coil spring causes the sleeve 3 to rotate and retract in the circumferential direction of the outer wall. At this time, the end of the core material 2 abuts against the position of the pig tonsil, and the sleeve 3 rotates and moves relatively, forming a component force toward the tonsil on the wall of the sleeve 3. At this time, the sampling head 4 is easier to rotate in and out under the action of rotation, and in the process of rotating in and out, the sampling head 4 can also move telescopically. Therefore, cutting and sampling can be performed by rotation at the sampling end, which improves the sampling speed, facilitates operation, reduces or alleviates the damage to the pig's oral cavity during the sampling process, and reduces the difficulty of sampling.

[0027] In addition, the starting trigger 5 can be manually pressed to start sampling, or the starting trigger 5 can also be connected to a power source to electrically control the sampling of the sampler. As long as the sampler is used for sampling, the type of driving force of the sampler is not specifically limited.

[0028] In order to improve the spiral cutting force of the coil spring 51 in the circumferential direction, in this embodiment, the front end of the coil spring 51 is sleeved on the outer wall of the sleeve 3 and abuts against the end of the through hole 11. At this time, the abutting surface between the front end of the coil spring 51 and the through hole 11 is a smooth surface, and the rear end of the coil spring 51 is directly fixedly connected to the upper part of the starting trigger 5. At this time, in order to improve the stability of the compression process of the coil spring 51, an abutting surface is provided at the abutting end 31, and the abutting surface is extended from the tube wall of the sleeve 3 to the surrounding direction. Correspondingly, the abutting surface can ensure that the coil spring 51 It is firmly fixed on the sleeve 3, and the abutment surface can also form a certain limiting effect on the coil spring 51 to prevent the spring 51 from bending and deforming and being sleeved on the outer wall of the sleeve 3; on this basis, it is ensured that the two ends of the coil spring 51 are respectively fixed to the starting trigger 5 and the abutment end 31 of the sleeve 3. In the process of compressing the coil spring 51, the coil spring 51 generates a spring torsion force along the circumferential direction, thereby ensuring that the sleeve 3 will rotate circumferentially with the twisting of the spring, making it easier for the sampling structure to cut the tonsils into the sampling structure, reducing the difficulty of sampling and improving the sampling efficiency.

[0029] The trigger 5 can drive the sleeve 3 to move back and forth along its length direction, so that the mating end 32 can move forward and can further drive the mating end 32 to slide relative to the protruding end 22, forming a sampling space at the pig tonsil position corresponding to the end of the sampling gun head.

[0030] A cylindrical sampling head 4 is installed at the position of the sampling gun head. The sampling head 4 has a certain length and is coaxially arranged with the core material 2 to facilitate sampling. The core material 2 can be set as a hollow tube, or a solid rod, which can be replaced according to different needs. In the present application, the core material 2 is set as a hollow tube, which can reduce the weight of the sampler itself, avoid shaking of the hand during the sampling process due to the excessive weight of the sampler, and reduce the difficulty of sampling.

[0031] In this embodiment, the sampling head 4 is detachably connected to the port of the protruding end 22 of the core material 2, and a groove 41 is provided on the sampling head 4 along the circumferential direction. According to actual conditions, the pig tonsils are located in the lower area of ​​the oral cavity. Correspondingly, the notch direction of the groove 41 of the sampling head 4 is set downward, which can ensure that the insertion sampler can be aligned with the pig tonsil position for direct sampling, thereby improving the sampling efficiency.

[0032] In addition, in order to ensure that the groove 41 is aligned with the pig tonsil, a limiting structure is formed at the connection between the sampling head 4 and the core material 2. Specifically, the limiting structure includes a first limiting member and a second limiting member. The first limiting member is arranged on the peripheral wall of the sampling head 4, and the second limiting member is arranged on the corresponding peripheral wall of the core material 2. The first limiting member and the second limiting member can be rotated to limit the position and direction of the groove 41, or the first limiting member and the second limiting member can be rotated by a certain angle after being snap-fitted, so as to limit the position and direction of the groove 41. At this time, the first limiting member can be a card convex protruding from the peripheral wall of the sampling head 4, and the number of the card convex is several, and the several card convex are distributed intermittently. Correspondingly, the second limiting member can be a card convex provided on the peripheral wall of the core material 2. The sampling head 4 is prevented from falling off during the sampling process by rotating the convex portion in the bayonet socket at a certain angle after being inserted into the bayonet socket, and the sampling head 4 has a guiding and limiting function, ensuring that the notch of the groove 41 is set downward. In the present embodiment, the first limiting member is set as an external thread of the outer peripheral wall of the sampling head 4, and the second limiting member is set as an internal thread of the port of the core material 2. At this time, the external thread and the internal thread are detachably connected and rotatably connected, and the direction of the groove 41 is limited to be set downward by the coordinated thread length and thread pitch, so as to form an accurate positioning of the sampling head 4. The structure is simple and easy to process, and the sampling head 4 can be ensured to be relatively stationary with the core material 2 during use. In addition, the sampling head 4 can also be cleaned and replaced to ensure that the sample can be accurately detected and avoid cross contamination of the sample.

[0033] In the present embodiment, in order to increase the single sampling amount, the groove 41 of the sampling head 4 is extended along the length direction of the sampling head 4, and the groove 41 is trapezoidal in the cross section of the length direction of the sampling head 4. Specifically, the width of the notch of the groove 41 is greater than the width of the bottom. The two side walls of the groove 41 are the front side wall and the rear side wall, that is, the front end side wall close to the sampling head 4 is recorded as the front side wall, and the rear side wall is arranged opposite to the front side wall. The front side wall and the end face of the sampling head 4 together form a spike portion. When viewed from top to bottom, the bottom of the spike portion is pointed to ensure that the groove 41 does not slide when it abuts against the tonsil. At this time, the cross-sectional shape of the front side wall and the end face of the sampling head 4 is an obtuse triangle. The end face of the sampling head 4 is inclined toward the rear side wall. When sampling, the side of the spike portion abuts against the throat of the pig tonsil. The spike portion Moving backwards facilitates sampling of the tonsils, and because the inclination direction of the front side wall of the groove 41 is the same as the inclination direction of the end face of the sampling head 4, and the inclination angle becomes gentler, that is, the front side wall of the groove 41 is sloped during the sampling process, which can ensure that the sample taken out can smoothly enter the sampling space formed by the groove 41, and can avoid damage to the oral cavity by the abutment part during the abutment process; the trapezoid can be an isosceles trapezoid, or it can also be a right-angled trapezoid, as long as it ensures that the sample located at the bottom of the groove 41 can smoothly enter; in addition, the groove 41 of the sampling head 4 is integrally formed with the sampling head 4, and the top ends of the two side walls of the groove 41 are flush with the outer peripheral wall of the sampling head 4, which can reduce the friction resistance of the sleeve 3 during the sliding process, avoid damage to the sampling structure during the sampling process, and reduce maintenance costs.

[0034] In order to reduce the friction resistance of the sleeve 3 during the forward sliding process, the inner diameter of the sleeve 3 is larger than the outer diameter of the core material 2, the sleeve 3 and the core material 2 are coaxially arranged, and the sleeve 3 and the core material 2 are clearance-matched. At this time, a connecting protrusion 33 is arranged at the matching end 32 of the sleeve 3, and the connecting protrusion 33 is arranged as a reducer, including a large diameter end 331 and a small diameter end 332. The large diameter end 331 and the small diameter end 332 are integrally formed, and the large diameter end 331 and the small diameter end 332 have the same inner diameter, and the large diameter end 331 is connected to the matching end 32 of the sleeve 3. Furthermore, the outer side wall of the large diameter end 331 is provided with an external thread, and the matching end 32 The inner wall is provided with an internal thread, so that the connecting boss 33 and the sleeve 3 are easy to disassemble and clean; the small diameter end 332 is protruded toward the sampling head 4, and the inner diameter of the small diameter end 332 is slightly larger than the outer diameter of the sampling head 4. Correspondingly, the diameter of the sampling head 4 is equal to the diameter of the core material 2. In this way, the small diameter end 332 and the sampling head 4 are over-matched to ensure the friction resistance of the small diameter end 332 during the forward sliding process, and further, a sliding buffer amount can be reserved between the core material 2 and the sampling head 4 to avoid the tube wall of the small diameter end 332 colliding with the core material 2 when the elastic potential energy of the coil spring 51 is restored, thereby causing damage to the connecting boss 33.

[0035] During assembly, the end of the small diameter end 332 is close to the rear end of the groove 41. Preferably, the tube mouth of the small diameter end 332 is flush with the rear end of the groove 41, so that sampling can be achieved with the least pressing force. In addition, during the sampling process, after pressing the start trigger 5, under the action of the coil spring 51, the small diameter end 332 moves forward and rotates circumferentially until the inner wall of the small diameter end 332 completely covers the groove 41, and the sampling is completed. At this time, the relative rotation and movement of the tube wall of the small diameter end 332 and the groove 41 form a cutting effect on the sample, which improves the cutting efficiency of the sample, shortens the sampling time, and reduces the difficulty of sampling; at the same time, the small diameter end 332 also forms a cover plate effect on the groove 41, that is, the inner wall of the small diameter end 332 has a certain pressure on the sample, which can ensure that the sample is in a stationary state in the groove 41, avoid the sample from falling off from the sampling space during the extraction process, ensure the weight of the sample, and the sample will not be contaminated, thereby ensuring the accuracy of the detection.

[0036] In order to improve the stability of sampling, the handpiece 1 has a convex portion arranged opposite to the position of the gun head and a hand holding portion for the hand to hold. The hand holding portion and the starting trigger 5 are arranged on the same side of the sleeve 3, and are both located below the sleeve 3. The hand holding portion is connected to one side of the convex portion and has an arc surface matching the shape of the tiger's mouth of the hand, forming a sampling stabilization effect with the hand holding portion as the fulcrum and the arc surface matching the shape of the tiger's mouth as the supporting surface. In detail, the convex portion is extended backward from the connecting end 21 of the core material 2, and the convex portion is detachably connected to the core material 2. After assembly, the rear side surface of the hand-held portion is connected to the bottom surface of the convex portion, and an arc-shaped surface is formed that bends downward. When sampling, the hand-held portion presses the trigger 5 to start the sampling end, and the sampling end generates a downward cutting force on the pig tonsil. In addition, the hand-held portion is a supporting point. Due to the principle of lever, the arc-shaped surface will overlap the tiger's mouth position, and the arc-shaped surface will generate a downward supporting force on the tiger's mouth position. The supporting portion 12 is just overlapped at the tiger's mouth position of the hand. At this time, the sampling head 4 will The position forms a forward and downward cutting force, and transmits the downward force to the handpiece 1 through the core material 2. Since the core material 2 has a certain length, the rear end of the core material 2 will generate a downward force at this time, that is, the support part 12 generates a corresponding supporting force to the base of the hand, so that it can be ensured that the force of the sampling head 4 during the sampling process is directed toward the pig tonsils, thereby improving the stability of the sampling, so that the force formed by the support part 12 and the force generated by the sampling head 4 support the support part 12, forming a lever stable structure with the handle as the fulcrum and the gun head and the support part 12 as the two force-bearing ends.

[0037] In this embodiment, the sampler also includes a controllable light source 7. Correspondingly, a mounting bracket is provided on the top of the outer peripheral wall of the through hole 11 of the handpiece 1. At this time, the controllable light source 7 can be detachably installed in the mounting bracket, that is, the controllable light source 7 is installed on the top of the handpiece 1, which is convenient for switching the controllable light source 7. In addition, the controllable light source 7 is columnar and is arranged parallel to the length direction of the core material 2. After the installation is completed, it can be ensured that the controllable light source 7 is always aimed at the position of the pig tonsil to emit light, which is convenient for sampling and avoids the visual blind spot during the sampling process.

[0038] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
