There are many types of gastroenterology diseases, a wide range of medical knowledge, and complex and delicate operations. When caring for gastroenterology patients, special attention should be paid to changes in the patient's condition. There are many samples that need to be sampled for testing. Many of these samples are contagious and infectious, and have a certain degree of pollution to other patients and the surrounding environment, which is not conducive to the health of other patients and medical staff. These samples need to be sealed, so we need a gastroenterology sampling, testing and sealing device.

[0003] The prior art is a patent application document CN218419905U that discloses a gastroenterology sampling, testing, sealing and storing device, including: a sampler, which includes a sampling head and a connecting rod, the sampling head and the connecting rod are fixedly connected, the sampling head is provided with a sampling slot for sampling the sample; a through hole running through the length of the storage shell is provided, one side of the connecting rod blocks one side of the through hole, and the sampler is movably inserted in the storage shell. The disadvantage of this device is that when the device extracts the sample, the surface of the sample is easily infected with other substances, which in turn has a certain impact on the test results.

[0004] In order to solve the above problems, the present invention proposes a gastroenterology sampling, testing and sealing device. Summary of the invention

[0007] Furthermore, the scraping component is a paddle, which is hinged to the bottom end of the cylinder, connected to the cylinder via a torsion spring, and abutted against the sampling tube.

[0008] Furthermore, the connecting parts are a block and a limit block. A push rod is fixedly arranged at the top of the sampling tube, and the end of the push rod away from the piston plate is fixedly connected to the first push handle; a slideway is arranged inside the push rod, and the block is arranged in the slideway; the top of the piston plate is fixedly connected to the piston rod, and the limit block is arranged on the outer circumferential surface of the piston rod.

[0009] Furthermore, the fixing assembly includes a buckle and an insert strip. The buckle is fixedly arranged on the outer circumferential surface of the tube body, and the insert strip is arranged on the cylinder and the plug cover. The insert strip is engaged with the buckle. A spring piece is arranged on the insert strip, and the spring piece is abutted with the buckle.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: A gastroenterology sampling, detection and sealing device, comprising a tube body 1, a plugging cover 21, and a cylinder 3. The plugging cover 21 and the cylinder 3 are both arranged at one end of the tube body 1, and the plugging cover 21 and the cylinder 3 are used alternately. The plugging cover 21 and the cylinder 3 are both detachably connected to the tube body 1 through a fixing assembly. The cylinder 3 is usually used in the sampling stage, and the plugging cover 21 is used in the transfer and storage stages. A scraping assembly is provided at the bottom end of the cylinder 3. When sampling the sample, the scraping assembly first contacts the sample and scrapes off the material on the surface of the sample to prevent the sampled sample from containing other substances and affecting the detection result of the sample.

[0029] A sampler is arranged in the tube body 1, and the sampler includes a sampling barrel 8. The sampling barrel 8 is slidably arranged in the tube body 1, and an opening is opened at the bottom end of the sampling barrel 8. A piston plate 14 is sealed and slidably arranged in the sampling barrel 8. The sampling barrel 8 and the piston plate 14 are matched with each other through a connecting piece. When the sampling barrel 8 moves upward, the piston plate 14 moves upward through the connecting piece.

[0030] A push rod 9 is fixedly provided at the top of the sampling barrel 8. The push rod 9 is hollow inside and arranged vertically. One end of the push rod 9 away from the sampling barrel 8 is fixedly connected to the first push handle 10. Two limit grooves 7 are symmetrically provided on the tube body 1. The limit grooves 7 are arranged vertically. The first push handle 10 is slidingly matched with the limit grooves 7. A piston rod 15 is fixedly connected to the top of the piston plate 14. A circular hole 17 is provided at the upper end of the sampling barrel 8. One end of the piston rod 15 away from the piston plate 14 passes through the circular hole 17 and the push rod 9 in sequence and is fixedly connected to the second push handle 16. The piston rod 15 is slidably connected to the sampling barrel 8. Two grooves are symmetrically provided at the upper end of the tube body 1. The second push handle 16 is clamped in the grooves, thereby limiting the movement direction of the second push handle 16.

[0031] The connecting parts are a stopper 19 and a limit block 20. Two slideways 18 are symmetrically fixedly arranged on the inner wall of the push rod 9. There are two stoppers 19, and the two stoppers 19 are fixedly arranged in the corresponding slideways 18. There are two limit blocks 20, and the two limit blocks 20 are symmetrically fixedly arranged on the outer circumference of the piston rod 15. The structure of the stopper 19 is as follows: Figure 6 As shown, the structure of the limit block 20 is as follows Figure 7 As shown. The stopper 19 and the limit block 20 are both triangular in shape, the stopper 19 is an upper triangle, the limit block 20 is a lower triangle, and the stopper 19 and the limit block 20 are both made of elastic material. The stopper 19 cooperates with the corresponding limit block 20 so that the limit block 20 moves with the piston rod 15.

[0032] A reset component is provided in the tube body 1, and the reset component is used to reset the sampling tube 8. The reset component is a spring 13. A first connecting ring 11 is fixedly sleeved on the outer circumference of the push rod 9, and the first connecting ring 11 is slidably connected to the tube body 1. A second connecting ring 12 is fixedly provided in the tube body 1. The spring 13 is provided between the first connecting ring 11 and the second connecting ring 12, one end of the spring 13 is fixedly connected to the bottom surface of the first connecting ring 11, and the other end of the spring 13 is fixedly connected to the top surface of the second connecting ring 12.

[0033] The scraping component is a paddle 4. There are two paddles 4, which are hinged to the bottom end of the cylinder 3 through a hinge shaft, and a torsion spring is sleeved on the hinge shaft, one end of the torsion spring is fixedly connected to the paddle 4, and the other end of the torsion spring is fixedly connected to the cylinder 3.

[0034] The fixing assembly includes two buckles 2 and an inserting strip 5. The two buckles 2 are symmetrically fixed on the outer circumference of the tube body 1. The inserting strip 5 is fixed on the cylinder 3 and the plug cover 21. One end of the inserting strip 5 is a triangular protrusion. The inserting strip 5 is engaged with the buckle 2 through the triangular protrusion. A spring piece 6 is fixedly connected to the inserting strip 5, and the spring piece 6 is in abutment with the buckle 2.

[0035] In summary, in the initial state, the cylinder 3 is mounted on the tube body 1, and the bottom end of the sampling tube 8 is in contact with the paddle 4. The stopper 19 is away from the limit block 20. The torsion spring is in a natural state.

[0036] When sampling is required, hold the tube body 1 and move the device to the location of the sample, so that the paddle 4 contacts the sample and pushes the first push handle 10 downward. The first push handle 10 moves downward with the push rod 9, and the push rod 9 moves downward with the sampling barrel 8 and the first connecting ring 11, and the spring 13 is compressed. The sampling barrel 8 pushes the paddle 4 to move, and the torsion spring is deformed by the force, so that the paddle 4 pushes away the material on the surface of the excrement during the opening process. With the opening of the paddle 4, the sampling barrel 8 is directly inserted into the uncontaminated sample. Since the sampling barrel 8 moves downward relative to the piston plate 14, the air pressure in the sampling barrel 8 is reduced, and the sample is adsorbed into the sampling barrel 8.

[0037] During this process, the push rod 9 moves downward with the stop block 19, and the limit block 20 slides upward relative to the push rod 9 on the slide 18. When the stop block 19 moves to the limit block 20, the inclined surface of the stop block 19 slides with the inclined surface of the limit block 20 until the stop block 19 is below the limit block 20, and the sampling tube 8 completes sampling.

[0038] After sampling is completed, the first push handle 10 is released, and the first connecting ring 11 moves upward under the action of the spring 13, and the first connecting ring 11 moves upward with the push rod 9, and the push rod 9 moves upward with the first push handle 10, the sampling tube 8, and the stopper 19 to return to the initial state. When the stopper 19 moves to the position of the limit block 20, the plane of the stopper 19 abuts against the plane of the limit block 20, and the stopper 19 pushes the limit block 20 to move upward, and the limit block 20 moves upward with the piston rod 15, and the piston rod 15 moves upward with the piston plate 14 to prevent the sample in the sampling tube 8 from being squeezed out.

[0039] As the piston plate 14 and the sampling barrel 8 move upward, the paddles 4 are rotated inwardly by the torsion spring, and then closed. When the sampling barrel 8 completely enters the cylinder 3, the two paddles 4 are completely closed.

[0040] When the sampling tube 8 is completely inserted into the tube body 1, the tip of the insert 5 is pressed by the finger, so that the triangular protrusion at the front end of the insert 5 enters the buckle 2. At this time, the cylinder 3 is directly ejected into the trash can under the elastic force of the spring 6, preventing the sample on the pick 4 from affecting the sample transfer.

[0041] Then, the insert strip 5 on the plug cover 21 is inserted into the buckle 2. At this time, the front end of the spring piece 6 is blocked by the buckle 2 and deforms and bends as the insert strip 5 enters until the triangular protrusion at the front end of the insert strip 5 passes over the buckle 2. Under the action of the spring piece 6, the triangular protrusion fits tightly with the buckle 2, so that the plug cover 21 is fixed on the tube body 1, preventing the sample from being contaminated during the transfer process, and preventing the second push handle 16 from being accidentally touched, resulting in the sample being squeezed out. The device is mainly used for samples that are not easy to flow, such as feces.

[0042] When testing is required, the insert 5 is pressed so that the plug cover 21 is ejected into the trash can under the elastic force of the spring 6, and then the second push handle 16 is pushed downward, and the second push handle 16 moves the piston plate 14 outward through the piston rod 15 to discharge the sample for testing.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
