Description

Technical Field

[0001] The utility model relates to a collector, in particular to a mid-section urine collector. Background Art

[0002] Urine test is a routine auxiliary means of clinical disease screening. The urine sample sent for test should be a "midstream urine sample"; but the current instrument is generally a cup plus a test tube. The user directly collects urine and pours the collected urine into the test tube. The urine sample in the test tube cannot be guaranteed to be midstream urine. Most of it is a mixture of front-end urine and midstream urine, which is then sent for testing. This will affect the accuracy of the test results.

[0003] The prior art CN219699973U provides a sampling device for laboratory use. The utility model is simple and convenient to operate, can ensure the cleanliness and hygiene of the sampling process, and effectively improves the accuracy of urine detection. After the collection cup is used to collect urine, the urine in the last liquid collecting chamber is poured out so that the middle urine can be taken out. However, the urine in the last liquid collecting chamber is affected by the rotating shaft sleeve and other components during the pouring process, so the last urine often leaves residues during the pouring process. When the switch assembly is opened to collect the middle urine, the float in the middle liquid collecting chamber will flow into the liquid outlet pipe, so that the float descending through hole is no longer blocked. At this time, the remaining urine in the last liquid collecting chamber will enter the middle liquid collecting chamber and mix with the middle urine, affecting the inspection structure. A solution is proposed below to the above problems. Utility Model Content

[0019] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0020] See Figures 1 to 3 As shown, a mid-stream urine collector comprises a collecting cup 1 and a urine collecting funnel 2 installed on the top of the collecting cup 1. The collecting cup 1 is made of transparent plastic, so that the operator can observe the urine collection situation easily. Two partitions 3 are installed inside the collecting cup 1. The collecting cup 1 is divided into an initial liquid collecting chamber 4, a middle liquid collecting chamber 5 and a final liquid collecting chamber 6 by the two partitions 3. A through hole 7 is opened in the center of the partition 3. The upper end surfaces of the two partitions 3 are both funnel-shaped structures. When urine is collected through the collecting cup 1, a sealing cover 21 is also hinged on the top of the urine collecting funnel 2. When collecting urine, the sealing cover 21 can be opened manually. A hand-held rod 12 is connected to the outer wall of the collecting cup 1. The patient holds the hand-held rod 12 and then aims the urine collecting funnel 2 at the urinary part, and the urine will enter the collecting cup 1 through the urine collecting funnel 2.

[0021] A float 8 is also provided in the initial liquid collecting chamber 4. The diameter of the float 8 is larger than the through hole 7. Urine will enter the initial liquid collecting chamber 4 through the through hole 7 opened on the two partitions 3. As the urine inside the initial liquid collecting chamber 4 increases, the float 8 gradually rises. A limit rod 20 is installed on the top of the float 8. One end of the limit rod 20 is slidably set in the through hole 7. By installing the limit rod 20 on the float 8, it can be ensured that the float 8 always moves toward the through hole 7 without deviation. When the initial liquid collecting chamber 4 is filled with urine, the float 8 will be exactly below the through hole 7, and the through hole 7 is sealed by the float 8.

[0022] When the urine in the initial liquid collecting chamber 4 is full, the urine will continue to be collected in the middle liquid collecting chamber 5. A sealing component 13 for sealing the through hole 7 is provided on the partition 3 between the middle liquid collecting chamber 5 and the final liquid collecting chamber 6. During the urine collection process, the operator can open the sealing component 13 to allow urine to enter the initial liquid collecting chamber 4 and the middle liquid collecting chamber 5. When the urine in the middle liquid collecting chamber 5 is full, the operator can close the middle liquid collecting chamber 5 through the sealing component 13, so that the front, middle and final sections of urine can be accurately segmented during uninterrupted urination, which effectively improves the patient's comfort and the accuracy of urine testing.

[0023] The lower part of the middle liquid collecting chamber 5 is connected with a liquid outlet pipe 9, and a storage tube 10 is threadedly connected to the end of the liquid outlet pipe 9. A control valve 11 is installed on the liquid outlet pipe 9. When the urine is collected and the middle urine needs to be selected for testing, the control valve 11 on the liquid outlet pipe 9 can be opened, so that the flow of liquid in the liquid outlet pipe 9 is no longer hindered, and the urine in the middle liquid collecting chamber 5 can enter the storage tube 10 through the liquid outlet pipe 9. The liquid outlet pipe 9 and the storage tube 10 are both arranged in a downward inclined shape. The inclined arrangement of the liquid outlet pipe 9 and the storage tube 10 facilitates the flow of urine. The storage tube 10 is a transparent structure, which is convenient for observing the urine entering the storage tube 10 so that the control valve 11 can be closed in time to prevent excessive urine from overflowing from the storage tube 10. When the urine in the protection tube is collected, the storage tube 10 can be removed from the liquid outlet pipe 9 by rotating the protection tube. A sealing sleeve is installed on the protection tube, and the sealing sleeve is plugged into the opening of the protection tube to prevent urine leakage.

[0024] The sealing assembly 13 includes a sealing plate 14, a connecting plate 15 and a spring 16. A T-slot 17 is provided between the partition plate 3 and the hand-held rod 12. The through hole 7 passes through the T-slot 17. The sealing plate 14 is slidably arranged in the T-slot 17. The sealing plate 14 can seal the through hole 7. The connecting plate 15 is fixed on the side wall of the sealing plate 14. The connecting plate 15 slides inside the partition plate 3 and the hand-held rod 12. One end of the spring 16 is fixed in the T-slot 17 of the hand-held rod 12. The other end of the spring 16 is fixed to the connecting plate 15. The top of the hand-held rod 12 is also provided with a slide groove 18 communicating with the T-slot 17, and a pull plate 19 is fixed to the bottom of the connecting plate 15. One end of the pull plate 19 passes through the slide groove 18 and is slidably arranged in the slide groove 18. When it is necessary to open the sealing component 13 so that urine can enter the initial liquid collecting chamber 4 and the middle liquid collecting chamber 5, the pull plate 19 on the hand-held rod 12 can be manually pulled to move. The pull plate 19 is arranged on the hand-held rod 12 so that the collecting hopper can be aimed at the urinary part through the hand-held rod 12, and the sealing can be controlled by one hand. The sealing assembly 13 is opened and closed by pulling the connecting plate 15 and the sealing plate 14 in the T-slot 17 through the pulling plate 19, so that the sealing plate 14 no longer seals the through hole 7, and urine can smoothly enter the initial liquid collecting chamber 4 and the middle liquid collecting chamber 5. When the pulling plate 19 pulls the connecting plate 15 to move, a section of the connecting plate 15 will squeeze the spring 16, so that the spring 16 generates elastic force. When the user observes that the urine in the middle liquid collecting chamber 5 is full, the pulling of the pulling plate 19 can be released. At this time, the connecting plate 15 will no longer squeeze the spring 16. The elastic force of the spring 16 can push the connecting plate 15 and the sealing plate 14 to reset. The sealing plate 14 seals the through hole 7. A rubber ring is also installed in the T-slot 17. The rubber ring is a U-shaped structure. The rubber ring cooperates with the sealing plate 14. The rubber ring is provided to facilitate the sealing of the through hole 7 by the sealing plate 14 to prevent the mixing of urine in the middle and the end. The user can also observe the reset distance of the pull plate 19 to ensure that the sealing plate 14 moves to the specified distance.

[0025] A drainage port is also provided at the bottom of the collection cup 1, and a rubber sealing plug 21 is clamped in the drainage port. After the midstream urine is collected, the rubber sealing plug 21 can be removed and the sealing assembly 13 can be opened to dispose of the remaining urine in the collection cup 1, so as to facilitate the subsequent disposal of the collection cup.

[0026] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
