technical field

The utility model relates to the field of medical appliances, in particular to a 24-hour urine protein sample sampling tube.

Background technique

For urine testing, it is best to take fresh samples and check them, otherwise the urine is likely to grow bacteria and change the chemical composition of the urine. The preservative commonly used in quantitative detection is generally xylene, which can form a film on the surface of urine to isolate the urine from the external environment to prevent bacterial reproduction. The dosage is 5ml-20ml xylene/1000ml urine.

After the urine sample is sent to the laboratory, the inspector needs to take out a certain amount of urine sample and transfer it to a new test tube, and then test it on the machine. However, during this operation, if the proportion of xylene in the urine sample is large, it may have a certain impact on the test results or the inspectors. Specifically, when the proportion of xylene in the urine specimen is large, the two Toluene may affect the accuracy of test results. In addition, because xylene is toxic and volatile, volatilized xylene may have a certain impact on the health of inspectors during the transfer of urine specimens. In this regard, the inventor believes that the above-mentioned situation can be prevented by improving the existing sampling tube.

Detailed ways

The utility model will be further described in detail below in conjunction with specific examples, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in FIG. 1 , this embodiment provides a 24-hour urine protein sample sampling tube, which includes a tube body 1 and a tube cap 2 .

The tube body 1 is used for storing urine samples, one end of which is open and the other end is closed, and the open end of the tube body 1 is provided with an external thread.

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

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

The outer wall of the top of the suction pipe 22 is snapped into the opening 213 of the partition 212, the top of the suction pipe 22 communicates with the cavity 211, and the bottom extends into the pipe body 1, and the side of the bottom of the suction pipe 22 The wall cloth is provided with several liquid suction holes 221 (see the partial enlarged view in FIG. 1 ).

The piston 23 is arranged in the cavity 211 of the cap shell 21, the piston 23 can move up and down between the limit ring 214 and the partition plate 212, and the circumference of the piston 23 is sealed with the inner wall of the cavity 211 fit. Moreover, in the initial state, the piston 23 is located in the cavity 211 close to the limit ring 214 (see FIG. 1 ).

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

The pull ring 24 is connected to the top of the telescopic rod 26 . Wherein, the function of the telescopic rod 26 is: when the piston 23 is at a low point, the telescopic rod 26 can be stretched to allow the pull ring 214 to move up, so as to facilitate the fingers to grasp the pull ring 214 and pull the piston 23 to move up.

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

The end cap 25 is screwed on the top of the cap shell 21 by means of threaded connection, and the end cap 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 Inside.

Wherein, the water-absorbing material 27 adopts polymer water-absorbing resin, which has strong water-absorbing ability, can absorb water hundreds of times its own weight, and has a strong water-retaining ability, and can lock the absorbed water .

It should be noted that the position corresponding to the liquid suction hole 221 on the tube body 1 is between 65% and 80% of the total capacity of the tube body 1 . That is, if the capacity of the tube body 1 is 20ml, then when the cap shell 21 is screwed on the open end of the tube body 1, when the liquid suction holes 221 are viewed from the outside of the tube body 1, each liquid suction hole 221 should be distributed in the range of 13ml to 16ml. between scales. The purpose of doing like this is: because xylene is floating on the urine surface, if therefore want xylene to be sucked away, then must allow liquid suction hole 221 to be positioned at a higher position, otherwise, if the position of liquid suction hole 221 is too high. If it is low, the suction pipe 22 may only suck the urine below the xylene, so that after the liquid is sucked, the xylene will not be sucked away and will still float above the urine.

The usage method and working principle of this embodiment are as follows:

Sample preparation:

The nurse pours the urine a to be tested into the tube body 1 of the sampling tube, the poured amount is about 80% of the capacity of the tube body 1, and then adds a certain amount of xylene b into the tube body 1 as a preservative , and then tighten the tube cap 2 on the open end of the tube body 1; after that, send the sampling tube to the inspection department for testing;

Before the inspection, the inspector needs to suck away the xylene b floating on the surface of the urine a in the tube body 1, and then suck a part of the urine into a new test tube, and then carry out the test on the machine; among them, the xylene b is sucked away The operation process of b is as follows:

First, remove the end cap 25 first, and then press down on the top of the pull ring 24 with your fingers to make the piston 23 move down to the lowest point. The state after the piston 23 moves down can be seen in Figure 2; the purpose of this step is to , to inject a certain amount of gas into the pipe body 1 to increase the air pressure in the pipe body 1 so that the liquid can be subsequently drawn from the pipe body 1;

Afterwards, pull the pull ring 24 slightly upwards with your fingers to allow the telescopic rod 26 to expand to an extended state. The expanded state can be seen in Figure 3;

Subsequently, keep the pipe body 1 in a vertical state, and then continue to pull the pull ring 24 upwards with your fingers, so that the piston 23 moves upwards to the highest point, and the state after the piston 23 moves upwards can be seen in Figure 4; during this process, the piston 23 moves upwards , the liquid on the upper part of the tube body 1 will be sucked away by the suction tube 22, so the xylene b floating on the surface of the urine a will be sucked into the suction tube 22 and the cavity 211 of the cap shell 21 as much as possible; If the xylene b cannot be easily sucked in the first step, then the tube body 1 can be slightly inclined in advance so that the xylene b is aligned with the liquid suction hole 221, and then the pull ring 24 is pulled upward;

Afterwards, the sampling tube is inclined so that the liquid in the suction pipe 22 flows into the cavity 211, and at the same time the liquid in the cavity 211 contacts the water-absorbing material 27 below the piston 23; will be absorbed, so the liquid sucked by the straw 22 will be absorbed and locked by the water-absorbing material 27 in this step, so as to prevent these liquids from leaking out and causing pollution to the environment;

After the xylene is sucked away, the inspector can remove the tube cap 2, then draw a certain amount of urine to a new test tube, and then put the test tube on the machine for testing.

It can be seen that the sampling tube of this embodiment can suck away the xylene b floating on the surface of the urine a as much as possible by pulling the pull ring 24 before opening the cap 2, so that the xylene b floating on the surface of the urine a can be prevented as much as possible during the follow-up detection. In addition, it can reduce the impact of xylene on the health of inspectors.

Example 2:

The difference between this embodiment and embodiment 1 is that the composition and structure of the suction pipe 22 are different, specifically:

Referring to Fig. 5, in this embodiment, the suction pipe 22 includes a connector 22a and a plurality of needles 22b;

The connector 22a is sealed and snapped into the opening 213 of the partition 212;

The top of each needle 22b is sealed and connected under the connector 22a by socketing, and the top of each needle 22b communicates with the cavity 211, and the bottom of each needle 22b extends into the tube body 1 The bottom of each needle 22b has a hole, and the inside has a liquid flow channel; and the position of the bottom of each needle 22b is different, and at the same time, the corresponding position of each needle 22b on the tube body 1 is also located at 65% of the total capacity of the tube body 1 to 80%;

Wherein, the structure of the needle 22b is the same as the needle used in the current syringe, which is an elongated structure with a tiny opening at the bottom.

In this embodiment, the advantage of the needle 22b is that the opening at the bottom is small, so even if the sampling tube is turned upside down, as long as the piston 23 is not pulled, the liquid in the tube body 1 will not flow into the cavity 211 by itself. The different positions of the bottoms of the needles 22b can expand the depth range of liquid absorption, so as to avoid the situation that the xylene b floating on the surface of the urine a cannot be absorbed.

The usage method and working principle of this embodiment are basically the same as those of Embodiment 1, so details will not be repeated here.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
