Technical Field

[0001] The invention relates to the technical field of urine collection, and in particular to a segmented urine collector. Background Art

[0002] At present, urine test is a common auxiliary means for clinical disease screening. The urine required for urine test is generally collected by the examinee himself and then handed over to the examiner for testing. However, the urine collection device used in clinical practice is generally a urine cup. Since disease detection often requires the collection of midstream urine in the morning, the existing urine collection device makes it difficult for patients to control the sampling of midstream urine, which in turn affects the test results.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 5 A urine segmented collector comprises a collector body 1, the collector body 1 is a top-opening structure, a drainage channel 2, a liquid inlet channel 3 and a collection channel 4 are arranged inside the collector body 1, the liquid inlet channel 3 is located between the collection channel 4 and the drainage channel 2, the collection channel 4 has a tubular outer shape and can be connected to a collection tube by plugging, and a flexible cover plate 5 is movably arranged on the top of the collection channel 4.

[0030] When the collector is in use, urine first enters the liquid inlet channel 3, and after overflowing from the liquid inlet channel 3, enters the collecting channel through the top of the flexible cover plate 5 (the flexible cover plate 5 sinks due to the pressure of the liquid on the top, and the liquid will push open the flexible cover plate 5 under the action of gravity and flow vertically downward, that is, enter the liquid inlet channel 3 from the gap between the flexible cover plate 5 and the inner wall of the liquid inlet channel 3). When the test tube is full of urine, that is, the collecting channel is full of liquid, the flexible cover plate 5 will float on the liquid surface to form a barrier. Under the blocking effect of the flexible cover plate 5 (the liquid under the flexible cover plate 5 supports it), urine can no longer enter the collecting channel, but will be naturally forced to flow to the discharge channel 2 to be discharged outward, thereby eliminating the possibility of mixing of urine from different sections and improving the accuracy of sample collection.

[0031] In this embodiment, the flexible cover plate 5 is made of non-woven fabric or paper. One side of the flexible cover plate 5 is fixed in the collector body 1 by a positioning pin. The top edge of the collection channel 4 protrudes upward, and is open on the side facing the positioning pin. The non-woven fabric or paper can meet the flexibility requirements of the collector.

[0032] In this embodiment, a liquid inlet funnel 6 is further included. The liquid inlet funnel 6 is arranged on the top of the collector body 1 , and the liquid can be introduced into the liquid inlet channel 3 through the liquid inlet funnel 6 .

[0033] In this embodiment, the bottom of the drainage channel 2 passes through to the bottom of the collector body 1, and a drainage hole 7 is provided at the bottom of the inlet channel 3 for discharging the liquid in the inlet channel 3. At the same time, its size limit can discharge the liquid without affecting the liquid entering the collection channel 4. The top height of the collection channel 4 is higher than the top height of the inlet channel 3. The drainage channel 2 is connected to the inlet channel 3 through the opening on the upper side thereof. When the liquid in the collection channel 4 is full, it enters the drainage channel 2 through the opening and is discharged.

[0034] In this embodiment, the collector body 1 is made of paper or plastic material with a waterproof layer inside, and the liquid inlet funnel 6 is made of paper or plastic material. If paper material is used, it is more conducive to the transportation of this product (for example, paper material can make this product foldable, and at the same time, the cost is lower than plastic and it is more environmentally friendly).

[0035] Example 2

[0036] like Figure 6-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that:

[0037] In this embodiment, an elastic rubber ring is provided on the outer side of the collection channel 4 , and the elastic rubber ring is used to prevent leakage at the connection between the test tube and the collection channel 4 when the test tube is inserted into the outer side of the collection channel 4 .

[0038] In this embodiment, first folding marks are arranged at the four corners of the liquid inlet funnel 6 , and second folding marks are arranged at both sides of the liquid inlet funnel 6 for folding the liquid inlet funnel 6 .

[0039] In this embodiment, the four sides of the top of the liquid inlet funnel 6 are connected (the material of the lining body 12 is the same as that of the liquid inlet funnel 6, and can be designed as an integrated whole with the liquid inlet funnel 6, and is connected by folds, and the lining body 12 can be turned over and folded at the top edge of the liquid inlet funnel 6) arranged inside the liquid inlet funnel 6, and the lining body 12 on both sides of the liquid inlet funnel 6 is provided with a third folding mark adapted to the second folding mark (when the two sides of the liquid inlet funnel 6 are compressed, the lining bodies 12 on both sides of the liquid inlet funnel 6 are together The inner ends of the four lining bodies 12 are provided with semicircular grooves 13, and the four lining bodies 12 and the semicircular grooves 13 form a guide channel for guiding urine into the liquid inlet channel 3 to avoid urine splashing into the discharge channel 2 when collecting urine. In the specific design, the initial shape of the lining body 12 can make its upper surface have a certain curvature, so that when the four lining bodies 12 are against each other, the gap between them is reduced.

[0040] In this embodiment, a fourth folding mark is provided at the bottom of the liquid inlet funnel 6 for adjusting the angle of the entire liquid inlet funnel 6 relative to the collector body 1, so as to be more adapted to the discharge direction of urine and facilitate the collection of urine.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
