[0002] Gastroenterology is a tertiary clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Gastroenterology has a wide variety of diseases, a broad range of medical knowledge, and complex and delicate operations. Currently, during gastroenterology examinations, it is necessary to take samples of the patient's urine for testing.

[0003] The prior art discloses a sampling device for gastroenterology examination, and the application publication number is CN215688068U. This application achieves the effect of quantitative sampling of urine by setting a threaded rod, a rotating disk and a connecting rod, and in this process, the urine will not be spilled. However, in order to ensure the accuracy and objectivity of the test results, it is generally necessary to sample midstream urine. Midstream urine is the middle urine after the urethra is flushed clean by urine, and this application cannot automatically sample midstream urine. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a sampling device for gastroenterology with an automatic reciprocating component for motion conversion power and an intelligent centering control component, which effectively solves the problem that the sampling devices for gastroenterology on the current market cannot automatically sample midstream urine.

Urine is collected through the sample collection component, the sample storage component stores the mid-stream urine and the front and back urine of urine respectively, the intelligent centering control component controls the front and back urine and the mid-stream urine to flow into different containers of the sample collection component respectively, and the weight control power component drives the motion conversion power automatic reciprocating component to control the working state of the intelligent centering control component according to the weight of the front urine and the mid-stream urine collected in the sample collection component.

[0006] Furthermore, the motion conversion power automatic reciprocating assembly includes a first limit rod, a second limit rod, a follower ring, a rotation conversion rod, a rotation conversion assembly and a torsion spring.

[0009] Furthermore, the sample storage assembly includes a fixed semi-ring, a clamping ring and a collecting tube. The fixed semi-ring is fixedly arranged on the weight control power assembly. The clamping ring is provided with two groups. One end of the clamping ring is hinged on the fixed semi-ring, and the other end of the clamping ring is clamped on the fixed semi-ring. There are two groups of collecting tubes. The two groups of collecting tubes are clamped in the fixed semi-ring and the clamping ring.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a sampling device for gastroenterology, which effectively solves the problem that the sampling devices for gastroenterology on the market currently cannot automatically sample midstream urine. This method brings the following advantages: (1) The ball valve is rotatably arranged in the liquid transfer tube. The ball valve rotates to connect the first-stage tube, the middle-stage tube and the last-stage tube to the liquid transfer tube, thereby achieving the effect of collecting the first-stage urine, the last-stage urine and the middle-stage urine respectively; (2) A rotation conversion rod is arranged in the rotating drum, and a circumferential inclined plate is arranged on the rotating rod, so that when the rotating drum moves downward, the rotating rod can be rotated under the action of the circumferential inclined plate, thereby realizing the control of the rotating drum and the ball valve; (3) A push plate, an arc-shaped shaft and a potential-accumulating spring are arranged at the top of the rotating rod, and the arc-shaped shaft can pass through the rotating plate, so that when the rotating rod rotates, the potential-accumulating spring can push the rotating plate to rotate, and then push the rotating drum to rotate, thereby achieving the effect of diverting the first-stage urine, the last-stage urine and the middle-stage urine; (4) The power block is arranged on the outer wall of the rotating drum. Due to the limiting effect of the first limiting rod on the power block, the rotating drum is in a stationary state, that is, the liquid transfer tube and the initial section tube are in a connected state. When the first limiting rod loses its limiting effect on the power block, under the action of the potential storage spring, the rotating plate rotates instantaneously, the rotating drum rotates instantaneously, the ball valve rotates instantaneously, and the liquid transfer tube is instantly connected to the middle section tube. When the second limiting rod loses its effect on the power block, the limiting block again limits the power block, and the liquid transfer tube is instantly connected to the final section tube. By providing the first limiting rod, the second limiting rod and the limiting block, the problem of the valve ball slowly disconnecting from the initial section tube and connecting to the middle section tube and slowly disconnecting from the middle section tube and connecting to the final section tube as the rotating rod rotates slowly is avoided, that is, the problem of inaccurate sampling of the middle section urine is avoided; (5) A torsion spring is arranged at the bottom end of the rotating rod, and a reset plate is arranged on the inner wall of the rotating cylinder. As the elastic potential energy accumulated in the torsion spring is released, the rotating rod rotates in the opposite direction, driving the push plate to rotate in the opposite direction, and the push plate pushes the reset plate to rotate in the opposite direction, thereby realizing the reverse rotation of the rotating cylinder, and then the valve ball returns to its initial position; (6) The sliding plate is slidably arranged on the vertical plate, and the follower ring is fixedly arranged on the sliding plate. As the amount of urine in the collection tube increases, the downward sliding distance of the follower ring gradually increases, thereby achieving the effect of automatically removing the quantitative first-stage urine and automatically sampling the quantitative mid-stage urine.
