[0010] As a further improvement of this utility model: a second tension spring is fixedly installed on one side surface of the fixed ring frame, and the other end of the second tension spring is rotatably connected to one side surface of the fixed plate.

[0011] As a further improvement of this utility model: a guide strip is fixedly installed on the inner wall of the sampling sleeve, and a guide groove adapted to the guide strip is opened on the surface of the moving disk. The moving disk is slidably connected to the sampling sleeve in the guide groove through the guide strip.

[0012] As a further improvement of this utility model: a spring is installed in a blind hole on the surface of the fixed plate, one end of the spring abuts against one end of a hemispherical protrusion that is slidably connected to the blind hole on the surface of the fixed plate, and a plurality of positioning holes that are adapted to the hemispherical protrusion are distributed in a ring on one side surface of the sampling head.

[0013] As a further embodiment of this utility model: a pull rope 1 covered by the protective sleeve extends along the groove opened on the outer surface of the sampling sleeve to one end of the sampling sleeve and is connected to a slide rod set at this end of the sampling sleeve.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1 to 9 As shown, a camel esophagus pharyngeal epithelial cell and mucus collection device includes a sampling sleeve 1, a sampling head 3 is provided at one end of the sampling sleeve 1, a plurality of arc-shaped protective covers 7 are wrapped around the outside of the sampling head 3, a fixing ring 6 is fixedly installed on the outside of the sampling sleeve 1 near the sampling head 3, a plurality of hinge seats 15 are installed on the surface of the fixing ring 6, and one side of each of the plurality of arc-shaped protective covers 7 is hinged to the surface of the hinge seat 15.

[0032] The inner surface of the arc-shaped protective cover 7 is provided with a guide groove 12, and a slide plate 11 is slidably connected in the guide groove 12. A tension spring 13 is fixedly installed on one side of the slide plate 11, and the other end of the tension spring 13 is fixedly installed in the guide groove 12 on the inner surface of the arc-shaped protective cover 7. A pull rope 8 is fixedly installed on one side of the slide plate 11, and the pull rope 8 is slidably connected in the through hole opened on the surface of the fixing ring 6.

[0033] The sampling head 3 is wrapped with multiple arc-shaped protective covers 7, which can effectively protect the sampling head 3 during the insertion and removal of the device, preventing the sampling head 3 from being contaminated or damaged. The hinge seat 15 on the fixing ring 6 provides a stable hinge point for the arc-shaped protective cover 7, allowing the arc-shaped protective cover 7 to be flexibly flipped, so that the sampling head 3 can be exposed during collection and wrapped for protection when not collecting. The guide groove 12 on the inner surface of the arc-shaped protective cover 7 is slidably connected to the slide plate 11. With the help of the tension spring 13 and the pull rope 8, the flipping action of the arc-shaped protective cover 7 can be made more stable and controllable. The tension spring 13 can drive the arc-shaped protective cover 7 to return to its original position after the tension is removed. The pull rope 8 passes through the through hole of the fixing ring 6, ensuring the stability of the tension transmission and allowing the operator to conveniently control the opening and closing of the arc-shaped protective cover 7 through the pull rope 8.

[0034] Furthermore, the surface of the sampling head 3 is equipped with a low-trauma rotating soft brush 4 and absorbent cotton 5, which are used to collect epithelial cells in the esophagus and absorb surrounding mucus, respectively.

[0035] The low-trauma rotating soft brush 4 is specifically designed for collecting epithelial cells, reducing damage to the esophagus and pharyngeal mucosa of camels and minimizing their stress response. It also effectively obtains complete epithelial cell samples. The absorbent cotton 5 can simultaneously absorb surrounding mucus, enabling simultaneous collection of epithelial cells and mucus, improving sampling efficiency, eliminating the need for two separate operations, and ensuring the integrity and synchronicity of the samples, thus providing a more comprehensive sample for subsequent testing.

[0036] Furthermore, the sampling sleeve 1 is made of shape memory metal inner core, and a protective sleeve 2 is fitted on the outside of the sampling sleeve 1. Both the protective sleeve 2 and the arc-shaped protective cover 7 are made of medical silicone.

[0037] The sampling sleeve 1 uses a shape memory metal inner core, which gives it good flexibility and resilience, allowing it to conform to the curved structure of the camel's esophagus and be easily pushed to the collection area, while ensuring sufficient structural strength. The outer protective sleeve 2 and the arc-shaped protective cover 7 are made of medical-grade silicone. Medical-grade silicone has good biocompatibility and lubricity, which can reduce friction between the device and the camel's esophagus and pharynx, reduce irritation and damage to the mucosa, improve the camel's comfort, and reduce stress response.

[0038] Furthermore, a fixing ring frame 16 is fixedly installed inside the sampling sleeve 1. A connecting rod 18 is slidably connected to the surface of the fixing ring frame 16. A spiral groove 19 is formed on the surface of the connecting rod 18 along its axial direction. A limiting sliding protrusion 17 is slidably connected inside the spiral groove 19. The limiting sliding protrusion 17 is fixedly installed on the inner side wall of the fixing ring frame 16. A fixing plate 20 is fixedly connected to one end of the connecting rod 18. A connecting screw 22 is fixedly installed on one side of the sampling head 3. The sampling head 3 is threadedly connected to one side surface of the fixing plate 20 through the connecting screw 22. A movable disk 25 is rotatably connected to the other end of the connecting rod 18. A second pull rope 26 is fixedly installed on one side surface of the movable disk 25. A lifting ring 27 is fixedly installed on one side surface of the fixing ring frame 16. One end of the second pull rope 26 is wound around the lifting ring 27 and extends through the movable disk 25 to one end of the sampling sleeve 1.

[0039] The fixed ring frame 16 provides stable support and sliding guidance for the connecting rod 18, ensuring the stability of the movement of the connecting rod 18. The spiral groove 19 on the surface of the connecting rod 18 cooperates with the limiting sliding protrusion 17, so that the connecting rod 18 can rotate simultaneously when sliding, thereby driving the sampling head 3 to rotate. This facilitates the low-trauma rotating soft brush 4 to collect epithelial cells more comprehensively and improve the sampling effect. The sampling head 3 is threadedly connected to the fixed plate 20 through the connecting screw 22, which facilitates the disassembly, replacement and cleaning of the sampling head 3, and makes subsequent maintenance and reuse convenient. The setting of the moving plate 25, the second pull rope 26 and the hanging ring 27 allows the operator to control the movement of the connecting rod 18 by pulling the second pull rope 26. The hanging ring 27 guides the second pull rope 26 to ensure the effectiveness and stability of the pull force transmission.

[0040] Furthermore, a tension spring 30 is fixedly installed on one side surface of the fixed ring frame 16, and the other end of the tension spring 30 is rotatably connected to one side surface of the fixed plate 20.

[0041] The tension spring 30 deforms when the connecting rod 18 is pulled, storing elastic potential energy. When the tension disappears, it can drive the connecting rod 18, the fixing plate 20 and the sampling head 3 to reset, so that the device can return to its initial state after the collection is completed.

[0042] Example 2

[0043] Improvements based on Example 1:

[0044] Furthermore, a guide strip 28 is fixedly installed on the inner wall of the sampling sleeve 1, and a guide groove 29 adapted to the guide strip 28 is opened on the surface of the moving disk 25. The moving disk 25 is slidably connected to the sampling sleeve 1 in the guide groove 29 through the guide strip 28.

[0045] The guide bar 28 cooperates with the guide groove 29 to guide and limit the sliding of the moving disk 25, ensuring that the moving disk 25 moves smoothly along a straight line and preventing it from rotating or deviating, thereby ensuring the stability and reliability of the movement of the connecting rod 18, and at the same time preventing the second pull rope 26 from getting tangled.

[0046] Furthermore, a spring 23 is installed in the blind hole opened on the surface of the fixing plate 20. One end of the spring 23 abuts against one end of the hemispherical protrusion 24 that is slidably connected in the blind hole opened on the surface of the fixing plate 20. Multiple positioning holes 21 that are adapted to the hemispherical protrusion 24 are distributed in a ring on one side surface of the sampling head 3.

[0047] Spring 23 pushes hemispherical protrusion 24 into positioning hole 21 of sampling head 3, which can position and fix sampling head 3, prevent sampling head 3 from loosening or rotating angle deviation during the collection process, and ensure the stability of sampling head 3. At the same time, when sampling head 3 needs to be disassembled, hemispherical protrusion 24 can be disengaged from positioning hole 21 with a little force, which is convenient to operate.

[0048] Furthermore, the pull rope 8 covering the protective sleeve 2 extends along the groove opened on the outer surface of the sampling sleeve 1 to one end of the sampling sleeve 1 and is connected to the slide rod 31 set at this end of the sampling sleeve 1. The pull rope 26 extends to one end of the sampling sleeve 1 and is connected to the slide rod 31. The slide rod 31 is slidably connected inside one end of the sampling sleeve 1, and a hand-held pull rod 32 is fixedly installed at one end of the slide rod 31.

[0049] Both pull rope 1 (8) and pull rope 2 (26) are connected to the slide bar 31. The operator can simultaneously control pull rope 1 (8) and pull rope 2 (26) by pulling the hand-held lever 32, thereby opening and closing the arc-shaped protective cover 7 and rotating the sampling head 3 for collection. The operation is centralized and convenient, improving the coordination and efficiency of the operation. The slide bar 31 is slidably connected inside the sampling sleeve 1 to ensure the stability of its movement. The hand-held lever 32 provides the operator with a comfortable grip and facilitates the application of force.

[0050] Furthermore, the surface of the arc-shaped protective shield 7 is fitted with a sponge 14, which is filled with a veterinary anesthetic.

[0051] Sponge 14 can absorb and store veterinary anesthetics. During device insertion, as it comes into contact with the pharyngeal mucosa of the camel's esophagus, the anesthetic can be slowly released, numbing the local mucosa, reducing the camel's pain and stress response, and making the sampling process smoother.

[0052] Working principle:

[0053] First, the operator inserts the sampling sleeve 1 with the sampling head 3 into the camel's mouth. Since the sampling sleeve 1 is made of memory metal core, it can conform to the natural curvature of the camel's esophagus. The medical silicone protective sleeve 2 and the arc-shaped protective cover 7 on its outer side are also made of medical silicone material, which can reduce friction and damage during the insertion process. At the same time, the arc-shaped protective cover 7 initially wraps around the sampling head 3, which plays a protective role.

[0054] Next, the device is continuously pushed to the collection area in the camel's throat. During the pushing process, the veterinary anesthetic filled in the sponge 14 installed on the surface of the arc-shaped protective cover 7 can play a role in reducing the camel's discomfort and stress response.

[0055] Upon reaching the collection area, the operator pulls the hand lever 32. This action has two effects. First, the hand lever 32 moves the slide bar 31, which in turn pulls the pull rope 8. Under the pulling force of the pull rope 8, multiple arc-shaped protective covers 7 rotate around the hinge seat 15. At this time, the slide plate 11 in the guide groove 12 on the inner surface of the arc-shaped protective cover 7 will slide accordingly, and the tension spring 13 will be stretched, ultimately exposing the sampling head 3 for collection operations.

[0056] On the other hand, when the hand lever 32 is pulled, the second pull rope 26 will also be pulled. The second pull rope 26 pulls the moving disk 25 to move. The moving disk 25 slides smoothly under the cooperation of the guide strip 28 on the inner wall of the sampling sleeve 1 and its own guide groove 29, thereby causing the connecting rod 18 to slide in the fixed ring frame 16. Since the spiral groove 19 on the surface of the connecting rod 18 cooperates with the limiting sliding protrusion 17 on the inner side wall of the fixed ring frame 16, the connecting rod 18 will rotate during the sliding process. The rotation of the connecting rod 18 drives the fixed plate 20 to rotate, and the sampling head 3 is threadedly connected to the fixed plate 20 through the connecting screw 22. Therefore, the sampling head 3 will also rotate accordingly.

[0057] When the sampling head 3 rotates, the low-trauma rotating soft brush 4 on its surface begins to collect epithelial cells in the esophagus, while the absorbent cotton 5 absorbs the surrounding mucus, achieving synchronous collection. During the collection process, the movement of the connecting rod 18 will cause the tension spring 2 30 to deform, and the cooperation between the hemispherical protrusion 24 and the positioning hole 21 can help the sampling head 3 to maintain stability to a certain extent.

[0058] After the collection is completed, the operator releases the hand lever 32, and the components reset under the elastic force of tension spring 13, tension spring 2 30, etc. The arc-shaped protective cover 7 wraps around the sampling head 3 again, and then the device is taken out of the camel's body, completing the entire collection process.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
