The purpose is to prevent the urine from being contaminated.
[0003] The collection of midstream urine has high requirements for aseptic conditions. Currently, urine cups are often used to collect midstream urine, which is then poured into glass test tubes with soft stoppers as midstream urine samples. In the process of transferring urine from the urine cup to the test tube, firstly, it is easy to spill urine when pouring urine into the test tube, and the amount collected is difficult to control; secondly, the glass test tube is fragile, and the soft stopper is easy to fall off, resulting in contamination or spillage of the specimen. In addition, the transportation and storage of glass test tubes are inconvenient, and the test tubes need to be placed vertically in a suitable special bracket.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0034] For example, see midstream urine. Figure 1 A medical liquid sample collection tube according to a specific embodiment includes a tubular middle tube 1, and both ends of the middle tube 1 are open; one end of the middle tube 1 extends to form a sample injection section 2, and the other end extends to form a sample outlet section 3; the free end of the sample injection section 2 is a sample injection port 201, and the free end of the sample outlet section 3 is a sample outlet 301, and the sample injection port 201 and the sample outlet 301 are both detachably connected with a sealing end cap 4, and the material of the middle tube 1 is a medical flexible material.
[0035] A medical liquid sample collection tube of the embodiment, the middle tube 1 is made of sterile medical flexible material, the two ends of the middle tube 1 are extended and formed into a sample inlet section 2 and a sample outlet section 3, and a detachable sealing end cover 4 is correspondingly provided on the sample inlet 201 and the sample outlet 301; in this way, when sampling, the sealing end cover 4 on the sample inlet 201 is removed, the sample inlet section 2 is inserted into a urine cup or other container containing urine, and then the middle tube 1 is squeezed to suck the middle section of urine into the middle tube 1, and then the sealing end cover 4 of the sample inlet 201 is covered, and the sampling is completed; when testing, first invert and mix, then remove the sealing end cover 4 on the sample outlet 301, so that the sample outlet 301 faces downward, and the middle tube 1 can be pressed lightly to complete the sampling; during use, there will be no spillage, the anti-pollution effect is good, and the collection is also very convenient and the collection amount is easy to control.
[0036] Please continue to see Figure 1 , wherein the sample inlet section 2 and the sample outlet section 3 are both in the shape of a pointed tube.
[0037] In this way, the sample inlet section 2 and the sample outlet section 3 are made into a pointed tube shape, which is convenient for suction and extrusion; it is also convenient to extend the sample inlet section 2 into different containers.
[0038] See also Figure 2 , wherein it also includes a hard sleeve 5, the middle tube 1 is covered in the lumen of the hard sleeve 5, both ends of the hard sleeve 5 are provided with openings, the sample inlet section 2 and the sample outlet section 3 pass through the openings at the corresponding ends from the ends of the hard sleeve 5, and a notch 501 is provided in the middle of the outer surface of the hard sleeve 5 to squeeze the middle tube 1;
[0039] The open ends of the sealing end caps 4 at both ends extend toward the direction of the hard sleeve 5 and are detachably connected to one end adjacent to the hard sleeve 5, and the inner surface of the sealing end cap 4 is adapted to the outer surface of the corresponding sample inlet section 2 or sample outlet section 3;
[0040] The sealing end covers 4 at both ends are made of the same material as the hard sleeve 5 .
[0041] In this way, the hard sleeve 5 is used to protect the middle tube 1 to prevent it from being squeezed, and a notch 501 is opened on the hard sleeve 5 to squeeze the middle tube 1; at the same time, the sealing end caps 4 at both ends can also be detachably connected to the hard sleeve 5, and a more stable and convenient detachable structure can be adopted. The function of the sealing end cap 4 is not only to seal the two ends to avoid contamination, but also to open the corresponding sealing end cap 4 on the sampling port 201 or the sample outlet 301 when sampling or discharging, and the other end is closed to form a negative pressure environment that is easy to squeeze to allow urine to enter and exit. During implementation, the hard sleeve 5 is divided into two shells in half along its length direction, and a common buckling structure in the prior art is provided between the two shells. The two shells are buckled together to wrap the middle tube 1 in the circular through groove, completing the assembly of the middle tube 1 and the hard sleeve 5.
[0042] Wherein, both ends of the hard sleeve 5 are provided with external threads.
[0043] The inner wall of the portion where the open ends of the sealing end covers 4 at both ends are connected to the hard sleeve 5 is provided with matching internal threads, and the sealing end covers 4 are threadedly connected to the hard sleeve 5.
[0044] In this way, when sampling, the sealing end cap 4 of the sample inlet section 2 is unscrewed; when the sample needs to be detected, the sealing end cap 4 of the sample outlet section 3 is unscrewed. It can be understood that the threaded connection part of the hard sleeve 5 and the sealing end cap 4 can be located on the intermediate tube 1, or on the sample inlet section 2 or the sample outlet section 3, which is selected according to the convenience of actual processing.
[0045] During implementation, the hard sleeve 5 and the sealing end covers 4 at both ends are connected by snap-fit.
[0046] In this way, the snap-fit structure is used to realize the detachable connection between the hard sleeve 5 and the sealing end caps 4 at both ends. When it is implemented, it is similar to the structure between the pen cap and the pen. When the sealing end cap 4 needs to be removed, it can be pulled open with a slight force.
[0047] See also Figure 3 and Figure 4 , wherein the cross-sections of the outer surfaces of the hard sleeve 5 and the sealing end covers 4 at both ends are both square.
[0048] In this way, the entire collection tube is placed horizontally in the box for sample delivery and will not roll.
[0049] Since the hard sleeve 5 is a square structure, the sealing end cover 4 is screwed on the hard sleeve 5 for convenience. Figure 5-Figure 8 As shown, the length of the hard sleeve 5 is slightly shorter than the intermediate tube 1, and a circular tubular connecting section 503 is extended outward at both ends of the hard sleeve 5, and an external thread is provided on the outer surface of the connecting section 502, and a corresponding internal thread connecting section 401 is provided on the sealing end cover 4. When the sealing end cover 4 is connected to the hard sleeve 5 through the connecting section 502, the sealing end cover 4 must be aligned with the hard sleeve 5 when the sample inlet 2 and the sample outlet 3 are closed.
[0050] During implementation, the sample inlet section 2, the intermediate tube 1 and the sample outlet section 3 are integrally formed.
[0051] The present invention can also adjust the diameter of the sample outlet 301 so that a drop of urine dripped out by lightly pressing the middle tube 1 is 10 microliters required for detection, so that there is no need for a special inoculation loop for smearing, streaking and culturing.
[0052] The above embodiment uses midstream urine as an example to introduce the use principle of the collection tube. The collection and sample delivery of other sterile body fluids such as pleural effusion, ascites, cerebrospinal fluid, etc. are similar.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
