Description

Technical Field

[0001] This invention relates to the field of animal sampling technology, and in particular to an animal sample collector based on cotton swabs. Background Technology

[0002] Cotton swabs are the most commonly used tool for animal sampling. For example, they are inserted into the animal's anus to collect fecal samples; swabs are used to wipe items around the animal to examine its living environment; and swabs are inserted into the animal's cavity to collect throat swabs. Regardless of the sampling method, after collection, the swab head needs to be broken off and placed into the appropriate test tube or EP tube for subsequent testing. Currently, this is done manually. However, because people wear gloves during sampling, it's difficult to break the swab, and the broken ends are often uneven. Furthermore, because the retained swab is relatively short, it's difficult to align the swab with the gloved hand, causing the sample to slip and requiring resampling, which is very inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an animal sample collector that facilitates the cutting of sampling swabs.

[0004] The present invention is achieved through the following measures: an animal sample collector based on a cotton swab, characterized in that it includes a shell with an open lower end, wherein the shell is provided with a clamping structure for the cotton swab hand end and a cutting structure for the cotton swab sampling end;

[0005] The clamping structure can slide up and down along the axis of the housing, and the upper part of the housing is provided with a release structure for the clamping structure.

[0006] The clamping structure includes a sliding seat slidably disposed inside the housing. The sliding seat includes two symmetrically arranged vertical plates. Clamping plates are rotatably disposed at both ends of the two vertical plates. The lower parts of the two clamping plates are connected by a spring. The spring is located below the rotation point of the clamping plate. The upper end of the clamping plate is offset towards the center of the housing.

[0007] The release structure is a round rod symmetrically arranged at the upper end of the housing;

[0008] The lower ends of the two clamping plates are held by the hand end of the cotton swab by the action of the springs. The sliding seat moves upwards, and when the upper end of the clamping plate touches the round rod, the upper end of the clamping plate presses down, and the lower end of the clamping plate swings to both sides about the axis of rotation. The springs are stretched, increasing the opening at the lower ends of the two clamping plates, allowing the cotton swab to disengage from the two clamping plates. The upper part of the clamping plate can be an arc-shaped plate offset towards the center of the housing, which facilitates the round rod pressing down on the clamping plate.

[0009] The cutting structure includes two mounting brackets symmetrically rotated and arranged at the lower part of the housing, with the two mounting brackets located on the outside of the clamping structure;

[0010] A cutting blade is provided on the inner side of the lower end of the mounting bracket. The upper part of the mounting bracket is connected to the housing via a tension spring. The tension spring is located above the rotating part of the mounting bracket, and the cutting blade is located below the rotating part of the mounting bracket.

[0011] The upper end of the mounting bracket is located on the upper part of the housing and offset towards the center of the housing, and the cutting blade drive rods are symmetrically arranged on the two upright plates;

[0012] The two cutting blades are kept at a certain distance by the action of a tension spring so that the cotton swab can pass through; when the sliding seat moves up, the two driving rods touch the upper end of the mounting bracket, the upper end of the mounting bracket rotates outward about the pivot point, the tension spring is compressed so that the lower ends of the two cutting blades move towards the center of the housing to cut the cotton swab, and when the cotton swab is cut, the upper end of the clamping plate touches the round rod.

[0013] The two upright plates are connected by a fixing plate, on which a pull rod is fixedly installed. The upper end of the pull rod can extend out of the housing, and spring pins for clamping the pull rod are symmetrically arranged on the housing.

[0014] The open end of the housing is provided with a cotton swab positioning ring, the inner diameter of which is larger than the outer diameter of the cotton swab.

[0015] The shell, cotton swab positioning ring, and cotton swab are generally arranged concentrically.

[0016] The two cutting blades are staggered and can contact each other on one side. The staggered arrangement ensures that the cotton swab is cut and also prevents damage to the cutting blades caused by excessive upward movement of the drive rod on the sliding seat.

[0017] The inner wall of the housing is provided with a sliding groove that allows the sliding seat to slide, and the upright plate is provided with a sliding plate that cooperates with the sliding groove.

[0018] For ease of handling, the housing is generally circular in shape and has an internal cavity for mounting the clamping and cutting structures.

[0019] The clamping plate and mounting bracket are generally V-shaped with an included angle greater than 90 degrees, and the rotating part is generally the connection point. The specific shape can be determined according to the actual situation.

[0020] To facilitate the installation of the cotton swab handpiece, the lower end of the clamping plate is designed as a curved surface.

[0021] The upper end of the mounting bracket must remain above the drive rod throughout the entire operation.

[0022] Working principle: Pushing the lever moves the clamping structure to the lower part of the housing. Passing the cotton swab hand-held end through the positioning ring causes the hand-held end to push open the two clamping plates. Once in the appropriate position, release the cotton swab, and the two clamping plates will clamp the cotton swab under the action of the spring. Because the sliding seat is located at the lower part of the housing, the portion of the cotton swab on the outer side of the housing is relatively long. At this time, the cotton swab can be moved by holding the housing to perform sampling.

[0023] After sampling is completed, pull the lever upwards. The lever moves the sliding seat and the cotton swab to the upper part of the shell, at which point the cotton swab exposed outside the shell gradually becomes shorter.

[0024] When the drive rod on the sliding seat approaches the upper end of the mounting frame, the sampling end of the cotton swab is aligned with or inserted into the test tube. The sliding seat continues to move upward and touches the upper end of the mounting frame, gradually lifting the upper end of the mounting frame. The lower end of the mounting frame swings inward along the rotation point and drives the cutting blade to cut the cotton swab.

[0025] After the cotton swab is cut, the sliding frame continues to move upward, so that the upper end of the clamping plate touches the round rod. The round rod presses down on the upper end of the clamping plate, and the lower end of the clamping plate swings outward along the rotation point. The openings of the two clamping plates become larger, and the cotton swab clamped between the two clamping plates detaches from the two clamping plates and falls from the bottom of the shell.

[0026] Finally, new swabs are installed for a new round of sampling.

[0027] The beneficial effects of this invention are: it facilitates the cutting of sampling swabs; the clamping and cutting of swabs are automatically triggered; and the remaining swabs after cutting can automatically fall off without affecting subsequent sampling. Attached Figure Description

[0038] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0039] See Figure 1-9 A swab-based animal sample collector includes a shell 1 with an open lower end, and the shell 1 has a clamping structure for the swab handheld end and a cutting structure for the swab sampling end.

[0040] The clamping structure can slide up and down along the axis of the housing 1, and the upper part of the housing 1 is provided with a release structure for the clamping structure.

[0041] The clamping structure includes a sliding seat 2 that is slidably disposed inside the housing 1. The sliding seat 2 includes two symmetrically arranged vertical plates 201. Clamping plates 3 are rotatably disposed at both ends of the two vertical plates 201. A shaft 202 is disposed on the vertical plate 201. The clamping plates 3 are rotatably disposed on the shaft 202.

[0042] The lower parts of the two clamping plates 3 are connected by springs 5, which are located below the rotation point of the clamping plates 3, and the upper ends of the clamping plates 3 are offset towards the center of the housing 1.

[0043] The release structure consists of round rods 8 symmetrically arranged at the upper end of the housing 1;

[0044] The lower ends of the two clamping plates 3 are clamped to the hand end of the cotton swab by the action of springs 5. When the sliding seat 2 moves upward, the upper end of the clamping plate 3 touches the round rod 8, the upper end of the clamping plate 3 presses down, and the lower end of the clamping plate 3 swings to both sides about the axis of rotation. The springs 5 ​​are stretched, which increases the opening at the lower end of the two clamping plates 3, and the cotton swab 10 is released from the two clamping plates 3. The upper part of the clamping plate 3 can be an arc-shaped plate offset towards the center of the shell 1, which makes it easier for the round rod 8 to press down on the clamping plate 3.

[0045] The cutting structure includes two mounting brackets 4 symmetrically rotated and arranged at the lower part of the housing 1. Shaft 2 104 is symmetrically arranged on the inner wall of the housing 1. The mounting brackets 4 are rotatably arranged on shaft 2 104. The two mounting brackets 4 are located on the outside of the clamping structure.

[0046] A cutting blade 401 is provided on the inner side of the lower end of the mounting bracket 4. The upper part of the mounting bracket 4 is connected to the housing 1 through a tension spring 6. The tension spring 6 is located above the rotating part of the mounting bracket 4, and the cutting blade 401 is located below the rotating part of the mounting bracket 4.

[0047] The upper end of the mounting bracket 4 is located on the upper part of the housing 1 and offset towards the center of the housing 1. The two upright plates 201 are symmetrically provided with cutting blade 401 drive rod 206.

[0048] The two cutting blades 401 are kept at a certain distance by the action of the tension spring 6 so that the cotton swab 10 can pass through; when the sliding seat 2 moves up, the two drive rods 206 touch the upper end of the mounting bracket 4, and the upper end of the mounting bracket 4 rotates outward about the axis of rotation. The tension spring 6 is compressed, causing the lower ends of the two cutting blades 401 to move towards the center of the housing 1 to cut the cotton swab 10. When the cotton swab 10 is cut, the upper end of the clamping plate 3 touches the round rod 8.

[0049] The two upright plates 201 are connected by a fixing plate 203. A pull rod 7 is fixedly installed on the fixing plate 203. The upper end of the pull rod 7 can extend out of the housing 1. Spring pins 9 for clamping the pull rod 7 are symmetrically arranged on the housing 1. A boss is provided at the upper end of the housing 1. Spring pin mounting holes 105 are generally symmetrically arranged on the boss.

[0050] The open end of the housing 1 is provided with a cotton swab positioning ring 103, the inner diameter of which is larger than the outer diameter of the cotton swab 10.

[0051] The housing 1, the cotton swab positioning ring 103, and the cotton swab 10 are generally arranged concentrically.

[0052] The two cutting blades 401 are staggered and can contact each other on one side. The staggered arrangement ensures that the cotton swab 10 is cut and also prevents damage to the cutting blades caused by excessive upward movement of the drive rod 206 on the sliding seat 2.

[0053] The inner wall of the housing 1 is provided with a groove 102 that allows the sliding seat 2 to slide, and the upright plate 201 is provided with a sliding plate 204 that cooperates with the groove 102.

[0054] For ease of handling, the housing 1 is generally circular in shape and has an internal cavity for mounting clamping and cutting structures. For example, a cylinder 101.

[0055] The clamping plate 3 and the mounting bracket 4 are generally V-shaped with an included angle greater than 90 degrees, and the rotating part is generally the connection point. The specific shape can be determined according to the actual situation.

[0056] To facilitate the installation of the cotton swab 10 hand-held end, the lower end of the clamping plate 3 is set as a curved surface; the upper end of the pull rod 7 is provided with a handle.

[0057] The upper end of the mounting bracket 4 must always be above the drive rod 206 throughout the entire operation.

[0058] See Figure 9 To ensure the compactness of the overall structure, a U-shaped opening 205 is provided on the clamping plate 3, and the mounting bracket 4 is located inside the U-shaped opening 205. This allows the upper end of the mounting bracket 4 to be as close as possible to the clamping plate 3, and the clamping plate 3 will not touch the mounting bracket 4 prematurely during the upward movement.

[0059] Working principle: Pushing the lever 7 pushes the clamping structure to the lower part of the housing 1. The hand-held end of the cotton swab 10 passes through the positioning ring 103, causing the hand-held end of the cotton swab 10 to push open the two clamping plates 3. After reaching the appropriate position, release the cotton swab 10, and the two clamping plates 3 clamp the cotton swab 10 under the action of the spring 5. Since the sliding seat 2 is located at the lower part of the housing 1, and the portion of the cotton swab 10 located on the outside of the housing 1 is relatively long, the housing 1 can be held by hand to move the cotton swab 10 for sampling.

[0060] After sampling is completed, pull rod 7 is pulled upwards. Pull rod 7 drives sliding seat 2 and cotton swab 10 to move towards the upper part of housing 1. At this time, the cotton swab 10 exposed outside housing 1 gradually becomes shorter.

[0061] When the drive rod 206 on the sliding seat 2 approaches the upper end of the mounting frame 4, the sampling end of the cotton swab 10 is aligned with or inserted into the test tube. The sliding seat 2 continues to move upward and touches the upper end of the mounting frame 4, gradually lifting the upper end of the mounting frame 4. The lower end of the mounting frame 4 swings inward along the rotation point and drives the cutting blade 401 to cut the cotton swab 10.

[0062] After the cotton swab 10 is cut, the sliding frame continues to move upward, causing the upper end of the clamping plate 3 to touch the round rod 8. The round rod 8 presses down on the upper end of the clamping plate 3, and the lower end of the clamping plate 3 swings outward along the rotation point. The opening of the two clamping plates 3 widens, and the cotton swab 10, which is clamped between the two clamping plates 3, detaches from the two clamping plates 3 and falls from the bottom of the shell 1.

[0063] Finally, a new round of sampling was conducted after installing a new swab (10).

[0064] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
