Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial sampling technology, and in particular to a sampling device for detecting animal pathogen microorganisms. Background Technology
[0002] Pathogenic microorganisms are microorganisms that can invade the human body or animals, causing infection or even infectious diseases. They are also known as pathogens. When humans or animals are infected with pathogenic microorganisms, they mostly appear in the respiratory system, digestive system, eyes, and other parts of the body. Therefore, it is necessary to use sampling equipment to sample the respiratory system, digestive system, eyes, and other parts of the body. Most existing sampling equipment uses sampling swabs for sampling. After sampling, the head of the swab is immersed in a preservation tube containing 2-3 ml of virus preservation solution and the head of the swab is broken off. The tube cap is then tightened and the tube is stored for subsequent culture. Although existing sampling swabs have folding marks at the tip to help break the swab head, the preservation solution in the preservation tube is easily splashed out when the swab head is inserted into the preservation tube and broken. Because the swab head is inserted into the preservation tube, the bending angle that can be used to break the swab head is very small. Sometimes the swab head cannot be broken in one go and needs to be broken several times with force in different directions. Secondly, because the diameter of the swab is usually very small, it is difficult to hold and thus difficult to apply force. When inserting the swab head into the animal's respiratory tract, anus, or other body parts for swabbing and sampling, sampling is more difficult. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a sampling device for detecting animal pathogens, so as to solve the problems of inconvenience of swab heads breaking and the laboriousness of sampling animals for microorganisms in the prior art.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sampling device for detecting animal pathogen microorganisms, comprising a grip, wherein a clamping member for holding a swab and a driving mechanism for driving the clamping member to slide along the axis of the grip are provided inside the grip, and a sliding cavity for accommodating the sliding of the clamping member is provided inside the grip along the axis of the grip, the sliding cavity comprising a conical cavity segment near the first end of the grip and a circular cavity segment extending toward the second end of the grip, the smaller end of the conical cavity segment being close to the circular cavity segment, and a tail end for accommodating the swab extending into the conical cavity segment along the axis of the grip at the first end of the grip. The inner insertion hole is coaxially arranged with the grip. The clamping member is an elastic clamp. When the elastic clamp is located in the conical cavity, the elastic clamp is in an open state to facilitate the insertion of the swab into the elastic clamp. When the elastic clamp slides in the circular cavity under the drive of the drive mechanism, the elastic clamp is forced to contract to clamp the tail end of the swab. The first end of the grip is movably provided with a fracture member for breaking the swab at the fracture mark on the swab. When the elastic clamp moves the swab so that the fracture mark of the swab is close to the fracture member, the fracture member can be manipulated to break the swab at the fracture mark.
[0005] Furthermore, the fracture component includes a flap disposed at the first end of the grip bar, the flap being rotatably connected to the grip bar via a hinge.
[0006] Furthermore, the hinge includes a spring hinge. The spring hinge keeps the flap in the open position, facilitating the insertion of the swab into the grip.
[0007] Furthermore, the elastic chuck includes a cylindrical base that slides with the inner wall of the circular cavity and clamping plates symmetrically arranged on the cylindrical base. One end of the clamping plate is hinged to the cylindrical base and is a free end. An elastic element is provided on the cylindrical base to force the clamping plate to rotate so that the free end of the clamping plate is away from the axis of the cylindrical base. A guide block is protruding on the outer wall of the cylindrical base and is arranged in a direction parallel to the axis of the grip. A guide groove is recessed on the inner wall of the circular cavity to slide with the guide block.
[0008] Furthermore, an elastic rubber layer is provided on the clamping surface of the clamping plate near the axis of the grip.
[0009] Furthermore, the driving mechanism includes a drive motor coaxially arranged with the grip, a transmission shaft coaxially fixedly connected to the output shaft of the drive motor, and a push-pull rod coaxially arranged with the transmission shaft. The drive motor is located near the second end of the grip. A threaded hole is provided inside the transmission shaft along the axis of the transmission shaft. One end of the push-pull rod is fixedly connected to the cylindrical base. The outer wall of the push-pull rod is provided with an external thread that mates with the threaded hole on the transmission shaft.
[0010] Furthermore, a power supply cavity is provided at the second end of the grip, and a battery for supplying power to the drive motor is provided inside the power supply cavity.
[0011] Furthermore, the drive motor is disposed within the circular cavity, and a partition is provided between the circular cavity and the power supply cavity, with the drive motor disposed on the partition.
[0012] Furthermore, the second end of the grip is detachably connected to a cover plate for opening or closing the power supply chamber.
[0013] Furthermore, the outer wall of the grip bar is provided with a control switch one for controlling the forward operation of the drive motor and a control switch two for controlling the reverse operation of the drive motor.
[0014] When using the above solution, firstly, control switch one controls the drive motor to run in the forward direction. The drive motor drives the transmission shaft to rotate in the forward direction. Through the threaded transmission between the transmission shaft and the push-pull rod, the elastic clamp slides along the axis of the grip rod into the conical cavity section. At this time, under the elastic force of the spring, the clamping plates open and move away from each other to facilitate the insertion of the swab between the two clamping plates. Insert the tail end of the swab into the conical cavity section through the insertion hole at the first end of the grip rod and into the space between the two clamping plates. Then, control switch two controls the drive motor to run in the reverse direction, causing the cylindrical base to slide closer to the drive motor. When the cylindrical base slides, the clamping plate is in the circular position. When the swab is inside the cavity, the inner wall of the circular cavity forces the two clamping plates to rotate and move closer together to clamp the tail end of the swab. At this point, the drive motor stops running. Hold the handle and insert the swab into the target area of the animal to wipe and collect microorganisms. After the head of the swab has collected microorganisms, continue to control the drive motor to run in reverse so that the swab gradually goes deeper into the handle. When the movement brings the fracture mark on the swab close to the flip plate and the insertion hole, use your thumb to push the flip plate to flip it and push the swab in the radial direction, breaking the swab at the fracture mark and separating the head and tail of the swab. Then, put the head of the swab into the storage tube. Next, control the drive motor to run in the forward direction so that the broken swab gradually extends out of the handle. When the clamping plate slides into the conical cavity, the spring forces the two clamping plates to open and move away from each other to release the swab and let it fall out of the handle.
[0015] Because the diameter of the handle is relatively large compared to the diameter of the swab, this invention uses the handle to control and operate the swab, making it convenient to hold and operate during sampling. At the same time, the swab can be broken at the fracture mark by the flip plate on the handle, making the swab breakage quick and convenient. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] like Figures 1-4 As shown, the sampling device for detecting animal pathogens of this utility model includes a handle 10. The handle 10 contains a clamping member for holding a swab 70 and a driving mechanism for driving the clamping member to slide along the axis of the handle 10. A sliding cavity is provided within the handle 10 along its axis, allowing the clamping member to slide. The sliding cavity includes a conical cavity section near the first end of the handle 10 and a circular cavity section 102 extending towards the second end of the handle 10. The smaller end of the conical cavity section is near the circular cavity section 102. The first end of the handle 10 has an insertion hole 103 for the tail end of the swab 70 to extend into the conical cavity section along the axis of the handle 10. 3. The gripper is coaxially arranged with the handle 10. The clamping member is an elastic clamp. When the elastic clamp is located in the conical cavity section, the elastic clamp is in an open state to facilitate the insertion of the swab 70 into the elastic clamp. When the elastic clamp slides in the circular cavity section 102 under the drive of the drive mechanism, the elastic clamp is forced to contract to clamp the tail end of the swab 70. The first end of the handle 10 is movably provided with a fracture member for breaking the swab 70 at the fracture mark 701 on the swab 70. When the elastic clamp moves the swab 70 so that the fracture mark 701 of the swab 70 is close to the fracture member, the fracture member can be manipulated to break the swab 70 at the fracture mark 701.
[0033] Combination Figure 1 , Figure 2 As shown, the fractured component includes a flap 41 disposed at the first end of the grip 10. The flap 41 is rotatably connected to the grip 10 via a spring 23 hinge. The spring 23 hinge keeps the flap 41 in an open state, making it convenient for the swab 70 to be inserted into the grip 10.
[0034] Combination Figure 1 , Figure 2As shown, the elastic chuck includes a cylindrical base 21 that slides against the inner wall of the circular cavity 102 and a clamping plate 22 symmetrically arranged on the cylindrical base 21. One end of the clamping plate 22 is hinged to the cylindrical base 21, and one end of the clamping plate 22 is a free end. The cylindrical base 21 is cylindrical in shape and is coaxially arranged with the handle 10. A spring 23 is provided on the cylindrical base 21 to force the clamping plate 22 to rotate so that the free end of the clamping plate 22 is away from the axis of the cylindrical base 21. One end of the spring 23 is fixedly connected to the cylindrical base 21, and the other end of the spring 23 is... Fixedly connected to the clamping plate 22, under the elastic force of the spring 23, the clamping plate 22 rotates, causing its free end to move away from the axis of the grip 10. To prevent the cylindrical base 21 from rotating when sliding inside the grip 10, a guide block is protruding on the outer wall of the cylindrical base 21. The guide block is arranged in a direction parallel to the axis of the grip 10. A guide groove is recessed on the inner wall of the circular cavity 102 to slide in cooperation with the guide block. The cooperation between the guide block and the guide groove ensures that the cylindrical base 21 can only slide along the axis of the grip 10 and cannot rotate around the axis of the grip 10. An elastic rubber layer is provided on the clamping surface of the clamping plate 22 near the axis of the grip 10 to increase the friction between the clamping plate 22 and the swab 70.
[0035] The driving mechanism includes a drive motor 31 coaxially arranged with the grip 10, a transmission shaft 32 coaxially fixedly connected to the output shaft of the drive motor 31, and a push-pull rod 33 coaxially arranged with the transmission shaft 32. The drive motor 31 is located inside the circular cavity 102 near the second end of the grip 10. The second end of the grip 10 is provided with a power chamber 104, and a battery 50 for supplying power to the drive motor 31 is provided inside the power chamber 104. The second end of the grip 10 is detachably connected to a cover plate 106 for opening or closing the power chamber 104. Specifically, an internal thread is provided on the inner wall of the power chamber 104, and an external thread is provided on the cover plate 106 that mates with the internal thread on the inner wall of the power chamber 104. The cover plate 106 is threadedly connected to the second end of the grip 10. A partition plate 105 is fixedly connected between the circular cavity 102 and the power chamber 104, and the drive motor 31 is disposed on the partition plate 105. The drive motor 31 is electrically connected to the battery 50. The output shaft of the drive motor 31 is positioned facing the first end of the grip 10. A control switch 61 for controlling the forward operation of the drive motor 31 and a control switch 62 for controlling the reverse operation of the drive motor 31 are provided on the outer wall of the grip 10. A threaded hole is provided along the axis of the transmission shaft 32. One end of the push-pull rod 33 is fixedly connected to the cylindrical base 21, and the other end of the push-pull rod 33 is located in the threaded hole of the transmission shaft 32. The outer wall of the push-pull rod 33 is provided with an external thread that mates with the threaded hole on the transmission shaft 32. To facilitate the installation and maintenance of the drive motor 31, the grip 10 is designed as a detachable connection structure. For example, the grip 10 can be disassembled into a front rod and a rear rod, which are threaded together to form the grip 10.
[0036] In use, this invention first controls the drive motor 31 to run forward via control switch 61. The drive motor 31 drives the transmission shaft 32 to rotate forward. Through the threaded transmission between the transmission shaft 32 and the push-pull rod 33, the elastic clamp slides along the axis of the grip rod 10 into the conical cavity section. At this time, under the elastic force of the spring 23, the clamping plates 22 open and move away from each other to facilitate the insertion of the swab 70 between the two clamping plates 22. The tail end of the swab 70 is inserted into the conical cavity section through the insertion hole 103 at the first end of the grip rod 10 and then between the two clamping plates 22. Then, the control switch 62 controls... The drive motor 31 reverses its rotation, causing the cylindrical base 21 to slide closer to the drive motor 31. When the cylindrical base 21 slides and the clamping plate 22 is located inside the circular cavity 102, the inner wall of the circular cavity 102 forces the two clamping plates 22 to rotate and move closer to each other, clamping the tail end of the swab 70. At this point, the drive motor 31 stops running, and the hand holds the handle 10 to insert the swab 70 into the target area of the animal to swab and obtain microorganisms. After the head of the swab 70 obtains microorganisms, the drive motor 31 continues to reverse its rotation, causing the swab 70 to gradually penetrate deeper into the handle 10. Figure 4As shown, when the movement brings the fracture mark 701 on the swab 70 close to the flap 41 and adjacent to the insertion hole 103, the thumb pushes the flap 41 to flip it in the radial direction, pushing the swab 70 to break it at the fracture mark 701, separating the head and tail of the swab 70. Then, the head of the swab 70 is placed into the storage tube. Next, the drive motor 31 is controlled to run forward, causing the broken swab 70 to gradually extend out of the handle 10. When the clamping plate 22 slides into the conical cavity, the spring 23 forces the two clamping plates 22 to open and move away from each other, releasing the swab 70 and causing it to fall out of the handle 10.
[0037] Since the diameter of the handle 10 is relatively large compared to the diameter of the swab 70, this utility model uses the handle 10 to control and operate the swab 70, which is convenient to hold and operate during sampling. At the same time, the swab 70 can be broken at the fracture mark 701 by the flap 41 on the handle 10, making the breakage of the swab 70 quick and convenient.
[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
