Description
Technical Field
[0001] The utility model relates to a collection device for detecting digestive tract tumors through fecal screening. Background Technique
[0002] Fecal examination is one of the common items in clinical routine examinations. Fecal examination provides the doctor with the patient's condition that cannot be seen by the naked eye, such as understanding whether the patient has an intestinal pathogenic bacteria infection, understanding the patient's digestive and absorption functions of the liver, biliary tract, pancreas, gastrointestinal tract and accessory glands, understanding whether the patient has inflammation, bleeding, ulcers and parasitic infections, screening for digestive tract tumors, and diagnosing and differentiating jaundice.
[0003] The object of fecal examination is fecal specimens. The existing collection methods of fecal specimens include cotton swab collection, collection spoon collection and brush collection. Although the cost is relatively low, these methods are basically in an open environment during collection, which may cause cross-infection when transferring fecal specimens, and the risk of fecal specimens dripping cannot be avoided. Once the fecal specimens are contaminated, the test results of the feces will be inaccurate. Content of the Utility Model
[0004] The purpose of the utility model is to provide a collection device for detecting digestive tract tumors through fecal screening, so as to solve the problems put forward in the above background technique.

[0007] It also includes a pushing component slidably arranged in the sampling tube and abutted against an elastic structure installed in the sampling tube. The pushing component can be inserted into a chute formed by the inner wall of the sampling tube and squeeze the elastic structure when moving directionally;
[0008] A sealing member is installed on the pushing component. When the pushing component rotates along the direction of the chute, the sealing member is controlled to block the through hole.

[0024] The following will describe in detail various exemplary embodiments, features and aspects of the present application with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.
[0025] The special term "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not necessarily have to be construed as superior to or better than other embodiments.
[0026] In addition, in order to better illustrate the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the gist of the present application.
[0027] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a collection device for detecting digestive tract tumors through fecal screening includes a sampling tube 1, a sliding groove 102, a through hole 103, a pushing assembly, a plugging member and an elastic structure.
[0028] Specifically, please refer to Figure 2 , Figure 3 ,Figure 4 , including:
[0029] A sampling tube 1, at an eccentric position at the end of the sampling tube 1, there is a through hole 103 provided;
[0030] It further includes a pushing component slidably arranged in the sampling tube 1 and abutted against an elastic structure installed in the sampling tube 1. The pushing component can be inserted into a chute 102 formed on the inner wall of the sampling tube 1, and when moving directionally, it squeezes the elastic structure;
[0031] A sealing member is installed on the pushing component. When the pushing component rotates along the chute 102, it controls the sealing member to perform a sealing operation on the through hole 103.
[0032] It should be noted that: the chute 102 is divided into a first strip-shaped groove, a second arc-shaped groove, and a third strip-shaped groove.
[0033] Specifically, in the embodiment, when using the collection device for detecting digestive tract tumors through fecal screening of the present utility model for collection work, by controlling the pushing component to move upward relative to the sampling tube 1 along the direction of the first strip-shaped groove, the elastic structure is squeezed. At this time, the pressure at the bottom inside the sampling tube 1 decreases, so that the collected feces are absorbed into the sampling tube 1. Under the limitation of the end of the first strip-shaped groove, the pushing component is controlled to rotate relative to the sampling tube 1 along the direction of the second arc-shaped groove, so as to drive the sealing member to rotate to align with the through hole 103, and the sealing member fits with the bottom inside the sampling tube 1. Under the elastic action stored in the elastic structure, the pushing component moves downward along the direction of the third strip-shaped groove, so that the sealing member is completely inserted into the through hole 103, so as to realize that while the sampling tube 1 completes the collection work, the sampling tube 1 can lock the position of the pushing component, and the sealing of the through hole 103 can avoid the possibility of cross-infection of the collected feces.
[0034] Please refer to Figure 4 , the pushing component includes a pushing rod 2, the pushing rod 2 is arranged along the axial direction of the sampling tube 1, and a piston 3 is rotatably connected to the end of the pushing rod 2. The piston 3 is in sealing sliding connection with the inner wall of the sampling tube 1.
[0035] Among them, the piston 3 can be made of rubber material to avoid air leakage due to the gap between the piston 3 and the inner wall of the sampling tube 1.
[0036] Preferably, at least one group of limiting grooves 101 are formed on the inner wall of the sampling tube 1, and limiting blocks 301 are formed on the piston 3 and are in sliding fit with the limiting grooves 101.
[0037] When the manual control push rod 2 moves upward, it can drive the piston 3 to move upward synchronously. At this time, the pressure between the piston 3 and the inner bottom of the sampling tube 1 decreases, so that the collected feces are absorbed into the sampling tube 1. Under the limiting effect of the limiting groove 101 and the limiting block 301, when the push rod 2 rotates relative to the piston 3, it can prevent the piston 3 from rotating synchronously and will not affect the sealed sliding connection between the piston 3 and the inside of the sampling tube 1.
[0038] A strip-shaped block 201 is arranged on the push rod 2, and the strip-shaped block 201 can be inserted into the sliding groove 102 and is in sliding fit with the sliding groove 102.
[0039] Please refer to Figure 4 , the elastic structure includes a sleeve 4 arranged in the sampling tube 1, a contact plate 6 is slidably arranged in the sleeve 4, and the push rod 2 penetrates through the sleeve 4 and the contact plate 6;
[0040] It also includes a first spring 5. The first spring 5 is arranged in the sleeve 4, one end abuts against the contact plate 6, and the other end abuts against the inner top of the sleeve 4.
[0041] An extrusion block 202 is arranged on the push rod 2 along the axial direction, and the extrusion block 202 can be inserted into the sleeve 4 and abut against the contact plate 6.
[0042] Specifically, when the above-mentioned push rod 2 moves upward, it drives the extrusion block 202 to move synchronously. When the extrusion block 202 moves upward, it squeezes the contact plate 6. At this time, the first spring 5 is compressed by the pressure of the contact plate 6 and stores elastic potential energy. When the strip-shaped block 201 moves to the upper end of the first strip-shaped groove, the elastic potential energy of the first spring 5 is at the maximum compression value. And under the limitation of the upper end of the first strip-shaped groove, the strip-shaped block 201 cannot move any more. At this time, the push rod 2 is controlled to rotate relative to the sampling tube 1, so that the strip-shaped block 201 slides into the second arc-shaped groove. When the push rod 2 rotates, it drives the sealing member to rotate synchronously. When the strip-shaped block 201 completely rotates to abut against the end of the second arc-shaped groove, the sealing member is aligned with the through hole 103 at this time. After that, the control of the push rod 2 is stopped. Under the elastic action of the first spring 5, the strip-shaped block 201 automatically slides into the third strip-shaped groove, so that the position of the push rod 2 is locked and the sealing member is inserted into the through hole 103, ensuring that the collected feces are in a closed space, preventing cross-infection of feces during the transfer process, and avoiding the collected feces from falling out of the sampling tube 1 during the transfer, causing environmental pollution.
[0043] Please refer to Figure 5, the plugging member includes an insertion cylinder 7, the insertion cylinder 7 is arranged at an eccentric position at the end of the push rod 2 and is connected to the end of the push rod 2, a plugging rod 8 is slidably arranged inside one end of the insertion cylinder 7 away from the push rod 2, and the other end of the plugging rod 8 abuts against the inner bottom of the sampling tube 1;
[0044] It further includes a second spring 9, the second spring 9 is arranged inside the insertion cylinder 7, one end of the second spring 9 abuts against the inner top of the insertion cylinder 7, and the other end abuts against the plugging rod 8.
[0045] Furthermore, in the initial state, the second spring 9 is in a compressed state. When the push rod 2 moves upward, it drives the insertion cylinder 7 to move synchronously. At this time, the elastic force generated by the second spring 9 on the plugging rod 8 makes the plugging rod 8 tend to move downward, so that when the insertion cylinder 7 moves upward relative to the plugging rod 8, the plugging rod 8 abuts against the inner bottom of the sampling tube 1 and does not separate. When the insertion cylinder 7 moves upward, the compression amount of the second spring 9 decreases. When the strip 201 completely moves to the end of the first strip groove, at this time, the second spring 9 is still in a compressed state, but the compression amount decreases. At this time, the bottom of the plugging rod 8 fits with the inner part of the sampling tube 1 (at this time, only the bottom of the plugging rod 8 fits with the inner bottom of the sampling tube 1, and no pressure is generated on the inner bottom of the sampling tube 1). When the strip 201 slides along the direction of the second arc groove to the end of the second arc groove, at this time, the plugging rod 8 is completely aligned with the through hole 103. When the strip 201 slides into the third strip groove, the insertion cylinder 7 drives the plugging rod 8 to move downward, so that the plugging rod 8 is inserted into the through hole 103, and the depth of the plugging rod 8 inserted into the through hole 103 is equal to the length of the third strip groove, so as to realize the plugging work inside the sampling tube 1 after sampling, and the plugging of the through hole 103 can avoid the possibility of cross-infection of the collected feces.
[0046] Preferably, a limiting protrusion 801 is formed on the plugging rod 8. When the strip 201 moves upward to the end of the first strip groove, the limiting protrusion 801 abuts against the inner bottom of the insertion cylinder 7, so that when the plugging state is released subsequently, when the insertion cylinder 7 moves upward, the plugging rod 8 moves upward synchronously, so as to realize the release of the plugging state of the through hole 103 by the plugging rod 8. And when the plugging rod 8 is aligned with the through hole 103 but not inserted into the through hole 103, under the action of the limiting protrusion 801, the plugging rod 8 cannot move relative to the insertion cylinder 7 and be inserted into the through hole 103.
[0047] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
