Detailed Description

The present utility model will be described in further detail with reference to specific examples, but embodiments of the present utility model are not limited thereto.

Example 1:

as shown in fig. 1, the present embodiment provides a 24-hour urine protein specimen sampling tube comprising a tube body 1 and a tube cap 2.

The tube body 1 is used for storing urine specimens, one end of the tube body is open, the other end of the tube body is closed, and external threads are arranged at the open end of the tube body 1.

The pipe cap 2 comprises a cap shell 21, a suction pipe 22, a piston 23, a telescopic rod 26, a pull ring 24, a water absorbing material 27 and an end cover 25.

The bottom of the cap shell 21 is provided with an internal thread, and the cap shell 21 is screwed on an external thread of the open end of the pipe body 1 through the internal thread so as to seal the open end of the pipe body 1. And, the inside of the cap shell 21 is provided with a cavity 211, the cavity 211 and the internal thread are separated by a partition plate 212, the middle part of the partition plate 212 is provided with an opening 213, and the inner wall of the upper half part of the cavity 211 is also provided with a circle of limiting ring 214.

The outer wall at the top of the suction pipe 22 is clamped in the opening 213 of the partition 212, the top of the suction pipe 22 is communicated with the cavity 211, the bottom of the suction pipe extends into the pipe body 1, and a plurality of liquid suction holes 221 (see a partial enlarged view in fig. 1) are arranged on the side wall at the bottom of the suction pipe 22.

The piston 23 is arranged in the cavity 211 of the cap shell 21, the piston 23 can move up and down between the limiting ring 214 and the partition plate 212, and the periphery of the piston 23 is in sealing fit with the inner wall of the cavity 211. And, in the initial state, the piston 23 is located in the cavity 211 at a position close to the stopper 214 (see fig. 1).

The telescopic rod 26 is connected to the top of the piston 23.

The pull ring 24 is attached to the top of the telescoping rod 26. Wherein, the telescopic rod 26 has the following functions: when the piston 23 is at a low point, the telescopic rod 26 can be stretched to enable the pull ring 214 to move upwards, so that fingers can conveniently scratch the pull ring 214 to pull the piston 23 upwards.

The water absorbing material 27 is attached to the bottom of the piston 23. The water absorbing material 27 is wrapped with a non-woven fabric, and the non-woven fabric is attached to the bottom surface of the piston 23 by bonding or binding.

The end cover 25 is screwed on the top of the cap shell 21 in a threaded connection manner, and the end cover 25 seals the piston 23, the pull ring 24, the telescopic rod 26 and the water absorbing material 27 in the cavity 211 of the cap shell 21.

Wherein, the water absorbing material 27 adopts a high molecular water absorbing resin, and the high molecular water absorbing resin has strong water absorbing capacity, can absorb hundreds of times of water of the self weight, has strong water retaining capacity and can lock the absorbed water.

It should be noted that, the position of the liquid suction hole 221 on the tube 1 is between 65% and 80% of the total volume of the tube 1. That is, if the capacity of the tube body 1 is 20ml, when the cap 21 is screwed on the open end of the tube body 1, each of the liquid suction holes 221 should be distributed between 13ml and 16ml of scale when the liquid suction holes 221 are seen in a plan view from the outside of the tube body 1. The purpose of this is to: since xylene floats on the surface of urine, if xylene is desired to be sucked away, the suction hole 221 must be located at a higher position, otherwise, if the position of the suction hole 221 is too low, the suction pipe 22 may only suck away urine under the xylene, so that the xylene is not sucked away after suction and still floats above the urine.

The application method and the working principle of the embodiment are as follows:

sample preparation:

pouring urine a to be detected into a tube body 1 of the sampling tube by a nurse, wherein the pouring amount is about 80% of the volume of the tube body 1, adding a certain amount of dimethylbenzene b into the tube body 1 as a preservative, and screwing a tube cap 2 at the open end of the tube body 1; then, the sampling tube is sent to a clinical laboratory to wait for detection;

before the test, the inspector needs to suck away the xylene b floating on the surface of the urine a in the tube body 1, then suck a part of urine into a new test tube, and then go on the machine for detection; the operation process of sucking away the dimethylbenzene b is as follows:

firstly, the end cover 25 is detached firstly, then the top of the pull ring 24 is pressed downwards by a finger, the piston 23 is enabled to move downwards to the lowest point, and the state of the piston 23 after the downward movement can be seen in fig. 2; the purpose of this step is to inject a certain amount of gas into the tube 1, so that the gas pressure in the tube 1 is increased, so that the liquid can be pumped from the tube 1 later;

after that, the pull ring 24 is slightly pulled upwards by a finger, so that the telescopic rod 26 is unfolded to an extension state, and the unfolded state can be seen in fig. 3;

subsequently, the tube body 1 is kept in an upright state, and then the pull ring 24 is pulled upwards by a finger, so that the piston 23 moves upwards to the highest point, and the state after the piston 23 moves upwards can be seen in fig. 4; in this process, when the piston 23 moves upward, the liquid in the upper portion of the tube body 1 is sucked away by the straw 22, so that the xylene b floating on the surface of the urine a is sucked into the straw 22 and the cavity 211 of the cap 21 as much as possible; if the xylene b cannot be conveniently sucked in this step, the tube 1 may be slightly tilted in advance to align the xylene b with the liquid suction hole 221, and then the pull ring 24 is pulled upward;

thereafter, the sampling tube is tilted so that the liquid in the pipette 22 flows into the cavity 211 while the liquid in the cavity 211 is brought into contact with the water absorbing material 27 under the piston 23; in this process, once the liquid contacts the water absorbing material 27, the liquid sucked by the suction pipe 22 is absorbed and locked by the water absorbing material 27, so as to prevent the liquid from leaking out and polluting the environment;

after the xylene is sucked away, the inspector can detach the tube cap 2, suck a certain amount of urine into a new test tube, and put the test tube on the machine for detection.

Therefore, the xylene b floating on the surface layer of the urine a can be sucked away as much as possible by pulling the pull ring 24 before the cap 2 is opened, so that the influence of the xylene on the detection result can be avoided as much as possible during subsequent detection, and meanwhile, the influence of the xylene on the health of the inspector can be reduced.

Example 2:

the difference between this embodiment and embodiment 1 is mainly that the constitution of the suction pipe 22 is different, specifically:

referring to fig. 5, in this embodiment, the straw 22 includes a connector 22a and a plurality of needles 22b;

the connector 22a is in sealing clamping connection with an opening 213 of the partition 212;

the top of each needle 22b is hermetically connected below the connector 22a in a sleeving manner, the top of each needle 22b is communicated with the cavity 211, and the bottom of each needle 22b extends into the pipe body 1; the bottom of each needle 22b is provided with an opening, and a liquid flow passage is formed in the bottom; the positions of the bottoms of the needles 22b are different, and the positions of the needles 22b on the tube body 1 are between 65% and 80% of the total capacity of the tube body 1;

the needle 22b is of an elongated structure, and has a small opening at the bottom, as in the case of the needles used in current syringes.

In this embodiment, the needle 22b has the advantage that its bottom opening is small, so that even if the sampling tube is inverted, the liquid in the tube 1 will not flow into the cavity 211 by itself, as long as the piston 23 is not pulled. The difference in the position of the bottom of each needle 22b can expand the depth range of the absorbed liquid to avoid the situation that the xylene b floating on the surface of the urine a cannot be absorbed.

The application method and the working principle of the present embodiment are basically the same as those of embodiment 1, and thus are not described herein.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
