Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a urine quantitative sampling device that does not require urine retention suspension. Background Art

[0002] In order to understand their own health conditions and detect diseases early, some people will regularly go to the laboratory for physical examinations. Urine testing is one of the three routine testing items in medical testing. Through urine testing, effective diagnosis and prevention of early kidney lesions, diabetes, etc. can be made. During the urine testing process, the person to be tested needs to use a urine sampling device to collect and sample their own urine.

[0003] The invention patent with the patent number CN113509212B discloses a urine quantitative sampling device for a laboratory that does not require urine retention suspension, including a receiving cup, a liquid guide seat, a baffle, a magnet, and a sponge block. The lower end of the receiving cup is provided with a liquid guide seat. A bracket is fixed on the upper surface of the movable seat, and a magnet is clamped and installed at the upper end of the bracket. A drain pipe is communicated with the side surface of the liquid guide seat, and a movable counterweight plate is axially connected to the inner wall of the drain pipe. A receiving groove is opened on the inner side of the movable counterweight plate, and a sponge block is arranged inside the receiving groove. This urine quantitative sampling device for a laboratory that does not require urine retention suspension can use the sponge to absorb and weigh the front-section urine, thereby controlling the automatic opening of the liquid collection hole, changing the urine flow direction inside the device, and thus collecting the middle-section urine of the user. At the same time, it can drive the liquid collection hole to close again under the action of urine buoyancy to achieve quantitative sampling. During the process, the user does not need to hold urine, effectively avoiding urine overflow.

[0004] The above device realizes the collection of the middle-section urine of the user through weight judgment. However, due to the different urine volumes of users, the middle-section urine should be based on the initial urine volume of the user. When patients with kidney damage have less urine, 20 ml to 70 ml of urine needs to be sampled for use. When the patient has more urine, 200 ml to 250 ml of urine should be sampled. However, the above device cannot adaptively sample the middle-section urine for patients with different urine volumes. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , an embodiment provided by the present invention: a urine quantitative sampling device without holding breath and stopping, including a sampling cylinder 1, a handle 3 is fixedly arranged on the side wall of the sampling cylinder 1, a funnel 2 is fixedly arranged on the top of the sampling cylinder 1, two shunt holes are fixedly arranged on the side wall of the sampling cylinder 1, drainage pipes 11 are fixedly arranged on the two shunt holes, outer frames 12 are fixedly arranged on the outer walls of the bottoms of the two drainage pipes 11, square frames 14 are fixedly arranged at the bottoms of the two drainage pipes 11, a drainage channel 13 is arranged in the middle of the two square frames 14, U-shaped limiting plates 10 are fixedly arranged on the bottoms of the inner walls of the two outer frames 12, measuring mechanisms 7 are arranged on the tops of the two U-shaped limiting plates 10, closing mechanisms 4 for closing the drainage pipes 11 are arranged on the side walls of the two measuring mechanisms 7, two locking mechanisms 5 are arranged inside the two measuring mechanisms 7, square frames 9 are sleeved on the outer walls of the two square frames 14, sampling bottles 8 are fixedly arranged on the bottoms of the two square frames 9, and a linkage mechanism 6 is fixedly arranged on the side wall of one of the closing mechanisms 4.

[0026] Specifically, the two measuring mechanisms 7 include U-shaped measuring plates 71 and two measuring springs 72. The two measuring springs 72 are fixedly arranged on the tops of the U-shaped limiting plates 10, and the U-shaped measuring plates 71 are fixedly arranged on the tops of the two measuring springs 72. The downward movement of the sampling bottle 8 and the square frame 9 drives the U-shaped measuring plate 71 to move downward to compress the measuring spring 72. When the compression reaches the maximum, when the square frame 9 can be pulled out from the side wall of the outer frame 12, a 50-milliliter urine sample is collected; automatic sampling is realized without the user having to hold breath and stop.

[0027] Specifically, each of the four locking mechanisms 5 includes an L-shaped plate 51, two rotating shafts 52, two rotating plates 53, and two fixing plates 54. Two receiving grooves are provided at the bottom of the square frame 9. The two rotating shafts 52 are rotatably arranged inside the two receiving grooves. The two rotating plates 53 are fixedly arranged on the two rotating shafts 52. The two fixing plates 54 are respectively fixedly arranged inside the two receiving grooves, and the two fixing plates 54 are respectively located on the sides of the two rotating plates 53 facing away from each other. By pulling out the sampling bottle 8 and the square frame 9 from the side wall of the outer frame 12, the rotating plate 53 is driven to abut against the L-shaped plate 51, and under the limitation of the fixing plate 54, the L-shaped plate 51 is driven to slide out. The L-shaped plate 51 is clamped on the side wall of the outer frame 12. When the sampling bottle 8 and the square frame 9 are inserted, the rotating plate 53 near the outside is limited by the fixing plate 54, so as to abut against the L-shaped plate 51 and push the L-shaped plate 51 back into the U-shaped measuring plate 71, enabling the U-shaped measuring plate 71 to reset under the action of the measuring spring 72; it realizes the limitation of the U-shaped measuring plate 71 when the sampling bottle 8 is taken out, and the U-shaped measuring plate 71 can be automatically reset when the sampling bottle 8 is inserted next time.

[0028] Specifically, sliding grooves 16 are provided on the side walls of the two outer frames 12.

[0029] Specifically, each of the two closing mechanisms 4 includes an arc-shaped plate 41 and an L-shaped closing rod 42. The L-shaped closing rod 42 is fixedly arranged on the side wall of the U-shaped measuring plate 71, the arc-shaped plate 41 is fixedly arranged on the top of the L-shaped closing rod 42, and the arc-shaped plate 41 is inserted into the side wall of the sampling cylinder 1. When the U-shaped measuring plate 71 moves downward, the L-shaped closing rod 42 and the arc-shaped plate 41 move downward synchronously, and the arc-shaped plate 41 moves downward to seal the drainage tube 11; it realizes the automatic sampling of the middle-section urine and avoids the urine from flowing out when the sampling bottle 8 is taken away.

[0030] Specifically, a vertical groove 15 is provided on the side wall of the sampling bottle 8.

[0031] Specifically, the linkage mechanism 6 includes two sliding rods 61, a stop rod 62, and an L-shaped linkage rod 63. The two sliding rods 61 are both limited and slide inside the vertical groove 15. The L-shaped linkage rod 63 is fixedly arranged on the side wall of the L-shaped closing rod 42 located above, and the stop rod 62 is fixedly arranged at the bottom of the L-shaped linkage rod 63. When the L-shaped measuring rod located above moves downward, the L-shaped linkage rod 63 and the stop rod 62 move downward synchronously, and the stop rod moves downward to limit the side wall of the square frame 9 below, so that the sampling bottle 8 cannot be taken out; it realizes the avoidance of errors in the test data caused by taking the wrong sampling bottle 8 when the patient has a large amount of urine.

[0032] Working principle: First, the user holds the handle 3 with the hand. The user aims at the funnel 2 to urinate. As the urine in the sampling cylinder 1 increases to 20 milliliters, the liquid level inside the sampling cylinder 1 rises to the drainage tube 11 and flows along the drainage tube 11 into the sampling bottle 8 below. The urine in the sampling bottle 8 gradually increases, driving the U-shaped measuring plate 71 to move downward to compress the measuring spring 72. When the sampling bottle 8 below is filled with 50 milliliters of urine, the sampling bottle 8 drives the U-shaped measuring plate 71 to compress the measuring spring 72 to the maximum extent. Then, when the U-shaped measuring plate 71 moves downward to the maximum extent, it synchronously drives the L-shaped closing plate and the arc-shaped plate 41 to move downward synchronously. The arc-shaped plate 41 closes the drainage tube 11. As the user continues to urinate, the liquid level inside the sampling cylinder 1 continues to rise, and the urine enters the sampling bottle 8 above from the drainage tube 11 above, repeating the previous steps. If the sampling bottle 8 above is filled with 50 milliliters of urine, at this time, the L-shaped closing rod 42 will drive the L-shaped linkage rod 63, the sliding rod 61 and the blocking rod to move downward synchronously. The blocking rod moves downward to block the side wall of the outer frame 12 below, making the sampling bottle 8 below unable to be taken out. At this time, take out the sampling bottle 8 above for testing. When the sampling bottle 8 above does not collect 50 milliliters of urine, at this time, the baffle cannot block the side wall of the outer frame 12 below. At this time, take out the sampling bottle 8 below for testing.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
