Description

Tight-fitting urine collection tube Technical Field

[0001] The present application relates to the field of medical testing technology, and in particular to a urine collection tube technology. Background Art

[0002] At present, fully automatic urine analyzers and urine sediment analyzers have been widely used in medical institutions in my country, and urine is automatically collected for subsequent testing using aspiration needles. Before this, inspectors had to manually unscrew the caps of the collection tubes one by one. This sample pre-processing mode not only increases the low-end and repetitive work of technicians, but also increases the occupational exposure risk of medical staff. The cap film in the existing technology is not firmly fixed and easily falls off, and the sealing of the collection tube is also insufficient. Therefore, the design of a tight-fitting, disposable urine collection tube that does not require opening can avoid the occurrence of the above problems, reduce the low-end and repetitive work of technicians, and make it easier for patients to take samples.

[0003] Summary of the Invention

[0005] The present application discloses a tightly buckled urine collection tube without opening the cover, which comprises the following components: an outer cover, a puncture membrane, an inner buckle and a tube body;

[0006] The puncture membrane comprises a base and a puncture portion, wherein the base is a circular ring, the puncture portion is circular, its diameter is equal to the diameter of the inner ring of the base and is arranged on the inner circle of the base, and the thickness of the puncture portion is thinner than the thickness of the base;

[0007] The outer cover comprises a cylinder and an inner ring, wherein the cylinder is cylindrical, the inner ring is in contact with the cylinder, and the inner ring is in the shape of a ring with a circular hole in the middle; an annular recess is provided on the inner ring; a thread and a sealing ring are provided at the bottom of the cylinder

[0008] The inner buckle is also annular and has an outer diameter slightly larger than that of the inner ring. The inner buckle is provided with an annular protrusion, which matches the annular recess on the inner ring.

[0009] The top of the tube body is provided with a thread; the diameter of the tube body is the same as the diameter of the cylinder of the outer cover and is connected via the thread.

[0010] In a preferred embodiment, the puncture membrane is provided with an annular depression, and is made of a soft material.

[0011] In a preferred example, the inner diameter of the puncture surface is ds, and the value range of ds is 0mm<ds≤15mm. The thickness of the puncture surface is t1, and the value range of t1 is 0.01mm≤t1≤5mm.

[0012] In a preferred embodiment, the volume of the tube is configured to be 5-20 ml.

[0013] In a preferred embodiment, one or more stop protrusions are provided on the outer side of the cover to prevent the urine collection tube from rolling randomly when placed horizontally on a horizontal surface.

[0014] In a preferred example, the inner ring can be arranged at any position inside the cylinder.

[0015] In a preferred embodiment, the bottom of the tube body may be nipple-shaped, conical or semicircular.

[0016] In a preferred embodiment, the tube body is provided with a scale groove for marking the sample amount required for sampling.

[0017] In a preferred embodiment, the puncture surface presents a slight upward or downward curvature.

[0018] In a preferred embodiment, the base of the puncture membrane is provided with an annular recess.

[0021] In a preferred embodiment, a limiting ring is disposed on the upper portion of the outer cover, and the distance between the limiting ring and the inner ring is equal to the thickness of the inner buckle.

[0022] In a preferred example, the sealing ring is arranged above the thread at the lower part of the cylinder.

[0023] In a preferred example, the base of the puncture membrane is slightly inclined upward or downward.

[0024] In a preferred embodiment, the annular protrusion in the middle of the inner ring is a spherical surface.

[0025] In a preferred embodiment, the inner wall of the top of the tube cover is configured as a frosted surface.

[0026] The advantages of the tight-fitting urine collection tube of the present application are:

[0027] 1) No need to remove the cover manually, the urine can be directly tested on the machine, which improves the automatic process of urine analysis.

[0028] Dadi has reduced the workload of inspectors, increased their working comfort, and improved their medical protection level;

[0029] 2) The tight-fitting cover-film combination design of the present application facilitates the patient's sampling experience. After assembly, the puncture membrane is fixed in the middle, eliminating the possibility that the puncture membrane may fall off due to misoperation during sampling, thereby causing damage, contamination or loss of the puncture membrane.

[0030] 3) By designing a fixing design combining the inner buckle and the inner ring, the puncture membrane can be fixed more firmly, thereby ensuring stability during transportation and use.

[0031] 4) By designing annular depressions on the puncture membrane and the inner ring, it can be better combined with the inner buckle, making it more stable.

[0072] Example 1

[0073] Specifically, an embodiment of the present invention is shown in Figures 1 to 8 and includes: an outer cover 1, a puncture membrane 2, a tube body 4, and an inner buckle 3. The puncture membrane 2 includes a base 5 and a puncture portion 6. The base 5 is a circular ring. The puncture portion 6 is circular, with a diameter equal to the diameter of the inner ring of the base 5 and disposed on the inner circle of the base 5. The thickness of the puncture portion 6 is thinner than that of the base.

[0074] The outer cover 1 includes a cylinder 7 and an inner ring 8, wherein the cylinder 7 is cylindrical, the inner ring 8 is inscribed in the cylinder 7, and the inner ring 8 is in the shape of a circular ring with a circular hole in the middle;

[0075] The inner buckle 3 is also annular and has an outer diameter greater than or equal to that of the inner ring. The inner buckle 3 is provided with an annular protrusion 9, which matches the annular depression on the inner ring.

[0076] The top of the tube body 4 is provided with a thread; the diameter of the tube body 4 is the same as the diameter of the cylinder 7 of the outer cover 1 and is connected via the thread.

[0077] It should be noted that the outer cover 1 and inner buckle 3 of this embodiment are made of hard materials, so there is sufficient friction between the outer cover 1 and the inner buckle 3 of the collection tube to fix them together. Therefore, the diameter of the inner buckle 3 of the collection tube is equal to the diameter of the barrel 7 of the outer cover 1. This embodiment also has vertical stripes on the lower middle part of the outer cover 1 to increase friction when gripping, and a label is drawn on the tube body 4 so that the user can more intuitively see the liquid content in the tube.

[0078] Example 2

[0079] Specifically, another embodiment of the present invention is shown in Figures 9 to 14 and includes: an outer cover 1, a puncture membrane 2, a tube body 4, and an inner buckle 3. The puncture membrane 2 includes a base 5 and a puncture portion 6. The base 5 is a circular ring. The puncture portion 6 is circular, with a diameter equal to the diameter of the inner ring of the base 5 and disposed on the inner circle of the base 5. The thickness of the puncture portion 6 is thinner than that of the base.

[0080] The outer cover 1 includes a cylinder 7 and an inner ring 8. The lower part of the cylinder 7 is cylindrical, and the top is truncated cone-shaped and shrinks inward. The shrinkage angle of the truncated cone is 0°-30°. The inner ring 8 is connected to the cylinder 7, and the inner ring 8 is in the shape of a circular ring with a circular hole in the middle. The inner ring 8 is provided with an annular depression. In this embodiment, an annular sealing ring 10 is provided at the lower part of the inner ring 8. The annular sealing ring 10 can be inserted into the cylinder 7 when tightened, thereby preventing liquid from overflowing and forming a sealing effect. The specific structural part of the inner ring of this embodiment is shown in Figure 9. The sealing ring is a conical structure that is wide at the top and narrow at the bottom. Compared with Example 1, the insertion effect of this embodiment is better than the covering effect of the ring.

[0081] The inner buckle 3 is also annular, with an outer diameter equal to or greater than that of the inner ring. It is equipped with an annular protrusion 9 that mates with the annular recess on the inner ring. In this embodiment, the width of the annular protrusion is smaller than that of the inner buckle, forming a structure that is wider at the top and narrower at the bottom, thereby matching the annular recess on the inner ring.

[0082] The top of the tube body 4 is threaded; the diameter of the tube body 4 is the same as that of the cylindrical body 7 of the outer cap 1, and they are connected by the threaded connection. It should be noted that the outer cap 1 and inner buckle 3 of this embodiment are made of soft materials, so the friction between the outer cap 1 and inner buckle 3 of this collection tube is insufficient to secure them. Therefore, the cap of this collection tube adopts an inward-conical design. After the inner buckle is inserted, it is restrained by the inward-conical design, ensuring that the inner buckle does not slip out.

[0083] Furthermore, it should be noted that in the patent application, relational terms such as first and second are used solely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "comprise," "include," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. Without further limitation, an element defined by the phrase "comprising a" does not preclude the presence of other identical elements in the process, method, article, or device comprising the element. In the patent application, reference to performing an action according to an element means performing the action at least according to that element, including two situations: performing the action only according to that element and performing the action according to that element and other elements. Expressions such as "multiple," "multiple," and "multiple" include "two," "twice," "two kinds," and "more than two," "more than two times," and "more than two kinds."
