Description

Technical Field

[0001] The utility model relates to the field of specimen sampling tools, in particular to a urine specimen sampler. Background Art

[0002] Traditional urine specimen sampling uses urine cups and test tubes. The sampling process is that the patient holds the urine cup and urinates into the cup, then hands the cup to the tester, who pours the urine into the test tube and then conducts the test. In this method, the urine cup moves, the urine is poured from the cup into the test tube, and the urine may spill during the movement of the test tube.

[0003] In order to solve the above problems, there are Figure 1 The improved urine specimen sampler shown comprises a sampling tube and a funnel. The sampling tube comprises a tube body and a tube cover covering the tube body. The tube cover has an insertion hole. The funnel is inserted into the insertion hole and extends into the sampling tube. When sampling, the patient holds the urine specimen sampler and urinates into the funnel. The urine directly leaks from the funnel into the sampling tube. Then the funnel is discarded and the sampling tube is sent for inspection. This urine specimen sampler eliminates the need to move a urine cup and pour urine from the urine cup into a test tube. It is not only more convenient, but also reduces the possibility of urine spilling.

[0004] However, urine specimen sampling has requirements for the amount of urine specimen sampling. A stool volume scale is set on the sampler, and the urine liquid level in the sampling tube should be kept near the stool volume scale as much as possible. Too little urine may not be enough for inspection, and too much urine is easy to overflow during the inspection operation. The above-mentioned urine specimen sampler does not have a structure to control the amount of urine retained. After the urine is discharged into the funnel and flows from the funnel into the sampling tube, there is generally some urine left in the funnel; when the funnel is pulled out, the space occupied by the funnel in the sampling tube is reduced, and the urine in the funnel continues to flow into the sampling tube. After the funnel is pulled out, the sampling tube is often filled with urine, resulting in too much urine. If the urine in the funnel is poured out first when the funnel is pulled out, or some urine is poured out from the sampling tube after the funnel is pulled out, it is easy to pour out too much urine, resulting in too little urine. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a urine specimen sampler which can control the amount of urine specimen retained.

[0006] The technical solution adopted to solve the above problems is: the urine specimen sampler includes a sampling tube and a funnel, the sampling tube includes a tube body and a tube cover covering the tube body, and the tube cover has a plug hole; the funnel includes a funnel body, a first funnel tube, a second funnel tube, a funnel one-way valve and a limiting structure; the second funnel tube is inserted into the tube cover and has an interference fit with the plug hole, the second funnel tube includes a coaxially arranged funnel tube outer sleeve and a funnel tube core part, the funnel tube core part is located in the funnel tube outer sleeve, and the funnel tube core part and the funnel tube core part are connected to the funnel tube. A funnel tube annular groove is formed between the outer sleeves of the funnel tube; the first funnel tube is inserted into the funnel tube annular groove and cooperates with the gap of the funnel tube annular groove so that the first funnel tube can move forward and backward, and the funnel one-way valve is arranged in the first funnel tube, and the funnel one-way valve can be opened backward in one direction. When the first funnel tube moves forward, the funnel tube core passes through the funnel one-way valve, and when the first funnel tube moves backward, the funnel one-way valve is closed; the limiting structure limits the first funnel tube from moving out of the funnel tube annular groove; the funnel body is connected to the first funnel tube.

[0007] Furthermore, the tube body is provided with a stool volume scale; when the funnel is used to take out the sampling tube and all the urine in the second funnel tube enters the sampling tube, the urine liquid level in the sampling tube is flush with the stool volume scale.

[0008] Furthermore, when the urine liquid surface in the sampling tube is flush with the stool volume scale, the amount of urine is mL.

[0009] Furthermore, the outer sleeve of the funnel tube is provided with a long hole arranged along the length direction of the outer sleeve of the funnel tube, and the limiting structure is a limiting rod, which is connected to the first funnel tube and inserted into the long hole.

[0010] Furthermore, the outer sleeve of the funnel tube is provided with an air hole, which is communicated with the bottom of the annular groove of the funnel tube.

[0011] Furthermore, the sampling tube includes a one-way valve on the tube cover, the one-way valve on the tube cover is arranged on the tube cover, the second funnel tube passes through the one-way valve on the tube cover, and the one-way valve on the tube cover is closed when the funnel is removed.

[0012] Furthermore, the funnel includes a funnel partition, which is arranged in the funnel body. The funnel partition divides the internal space of the funnel body into a specimen urine space and a waste urine space. The specimen urine space is connected to the first funnel tube. The volume of the specimen urine space is mL, and the upper edge of the funnel partition is lower than the upper edge of the funnel body.

[0013] The beneficial effects of the utility model are as follows: the urine sampling process using the utility model is as follows: Figure 6 As shown, the funnel is inserted into the sampling tube, the first funnel tube is in the forward state, the core of the funnel tube passes through the one-way valve of the funnel, and the one-way valve of the funnel is in the open state. Hold the urine specimen sampler and put urine into the funnel. Since the one-way valve of the funnel is in the open state, urine flows from the second funnel tube into the sampling tube. Then pull out the funnel. When the funnel is pulled out, Figure 7As shown, due to the clearance fit between the first funnel tube and the annular groove of the funnel tube, and the interference fit between the second funnel tube and the jack, the first funnel tube moves forward, so that the one-way valve of the funnel moves backward without being passed through by the core of the funnel tube, and the one-way valve of the funnel is closed. Continue to pull out the funnel, because the first funnel tube has moved backward to the limit position, it will drive the second funnel tube to move backward; at this time, because the one-way valve of the funnel is closed, the urine in the funnel is restricted from flowing into the sampling tube. As long as the second funnel tube occupies a larger space in the sampling tube, the sampling tube can be prevented from being filled, ensuring that there is a distance between the liquid surface of the retained urine and the upper edge of the tube body, thereby preventing urine from overflowing during subsequent inspection operations.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 2 to 5As shown, the urine specimen sampler includes a sampling tube 1 and a funnel 2. The sampling tube 1 includes a tube body 11 and a tube cover 12 covering the tube body 11, and the tube cover 12 has a plug hole 121; the funnel 2 includes a funnel body 21, a first funnel tube 23, a second funnel tube 24, a funnel one-way valve 25 and a limiting structure; the second funnel tube 24 is inserted into the tube cover 12 and has an interference fit with the plug hole 121, and the second funnel tube 24 includes a coaxially arranged funnel tube outer sleeve 241 and a funnel tube core 242, the funnel tube core 242 is located in the funnel tube outer sleeve 241, and the funnel tube core 242 and the funnel tube outer sleeve A funnel tube annular groove 243 is formed between 241; the first funnel tube 23 is inserted into the funnel tube annular groove 243 and cooperates with the gap of the funnel tube annular groove 243 so that the first funnel tube 23 can move forward and backward, and the funnel one-way valve 25 is arranged in the first funnel tube 23, and the funnel one-way valve 25 can be opened backward in one direction. When the first funnel tube 23 moves forward, the funnel tube core 242 passes through the funnel one-way valve 25, and when the first funnel tube 23 moves backward, the funnel one-way valve 25 is closed; the limiting structure limits the first funnel tube 23 from moving out of the funnel tube annular groove 243; the funnel body 21 is connected to the first funnel tube 23.

[0024] The urine sampling process using the utility model is as follows: Figure 6 As shown, the funnel 2 is inserted into the sampling tube 1, the first funnel tube 23 is in a forward state, the funnel tube core 242 passes through the funnel one-way valve 25, and the funnel one-way valve 25 is in an open state. Hold the urine specimen sampler and release urine into the funnel 2. Since the funnel one-way valve 25 is in an open state, urine flows from the second funnel tube 24 into the sampling tube 1. Then pull out the funnel 2. When the funnel 2 is pulled out, as shown in FIG. Figure 7 As shown, since the first funnel tube 23 and the funnel tube annular groove 243 are in clearance fit, and the second funnel tube 24 and the insertion hole 121 are in interference fit, the first funnel tube 23 moves forward, so that the funnel one-way valve 25 moves backward without being passed through by the funnel tube core 242, and the funnel one-way valve 25 is closed. Continue to pull out the funnel 2, because the first funnel tube 23 has moved backward to the limit position, it will drive the second funnel tube 24 to move backward; at this time, because the funnel one-way valve 25 is closed, the urine in the funnel 2 is restricted from flowing into the sampling tube 1. As long as the second funnel tube 24 occupies a larger space in the sampling tube 1, the sampling tube 2 can be prevented from being filled, ensuring that there is a distance between the liquid level of the retained urine and the upper edge of the tube body 11, thereby preventing urine from overflowing during subsequent inspection operations.

[0025] The tube body 11 of the utility model can be provided with a stool volume scale 111 as in the prior art. When the urine liquid level in the sampling tube 1 is flush with the stool volume scale 111, the amount of urine is 10mL. The second funnel tube 24 extends into the tube body 11 and extends below the stool volume scale 111. The funnel 2 takes out the sampling tube 1, and the second funnel tube 24 moves backward to reduce the occupation of the space in the tube body 11, and the urine in the second funnel tube 24 enters the tube body 11; the volume of the second funnel tube 24 below the stool volume scale 111 is made the same as the volume of urine accommodated by the hole of the second funnel tube 24, and the effect of the urine liquid level in the sampling tube 1 being flush with the stool volume scale 111 can be basically obtained when the funnel 2 takes out the sampling tube 1 and the urine in the second funnel tube 24 all enters the sampling tube 1. During actual sampling, even if there is an error, the urine liquid level in the sampling tube 1 is finally near the stool volume scale 111, which meets the requirements.

[0026] The limiting structure is used to limit the first funnel tube 23 from moving out of the funnel tube annular groove 243, that is, to prevent the first funnel tube 23 from being disengaged from the second funnel tube 24. The specific structure of the limiting structure can be as follows: the funnel tube outer sleeve 241 has a long hole 2411 arranged along the length direction of the funnel tube outer sleeve 241, and the limiting structure is a limiting rod 26, which is connected to the first funnel tube 23 and inserted into the long hole 2411. Figure 7 As shown, during the process of pulling out the funnel 2, the first funnel tube 23 moves backward, and the limiting rod 26 also moves backward. When the limiting rod 26 moves backward to fit the rear end wall of the long hole 2411, the first funnel tube 23 moves backward to the limit position. If the funnel 2 is continuously pulled out, the limiting rod 26 drives the second funnel tube 24 to move backward.

[0027] In order to prevent the air pressure in the funnel tube annular groove 243 from affecting the forward and backward movement of the first funnel tube 23 , the funnel tube outer sleeve 241 preferably has an air hole 2412 , and the air hole 2412 is connected to the bottom of the funnel tube annular groove 243 .

[0028] After the urine sampling is completed, the sampling tube 1 needs to be taken to the inspection site. In order to prevent the urine in the sampling tube 1 from spilling out during this process, the sampling tube 1 preferably includes a tube cover one-way valve 13, which is arranged on the tube cover 12, and the second funnel tube 24 passes through the tube cover one-way valve 13. The tube cover one-way valve 13 is closed when the funnel 2 is removed. During sampling, since the second funnel tube 24 passes through the tube cover one-way valve 13, the one-way valve 13 does not affect the urine entering the sampling tube 1. When the funnel 2 is pulled out, the cover one-way valve 13 rebounds and closes, thereby preventing the urine in the sampling tube 1 from spilling out.

[0029] The tube cover one-way valve 13 and the funnel one-way valve 25 both adopt the structure of the existing one-way valve, that is, a conical silicone sheet with three or four slits extending radially outward from the center of the silicone sheet. The elasticity of the silicone sheet closes the slits, and the one-way valve is closed. When the tube passes through the silicone sheet, the slits are stretched open.

[0030] During the urine specimen sampling process, since the diameter of the hole on the second funnel tube 24 for urine to flow into the sampling tube 1 is difficult to be large, and there is the influence of the air in the sampling tube 1, the speed of urine flowing from the funnel 2 into the sampling tube 1 is not fast, and is obviously slower than the flow rate of the patient's urine. The urine retained in the funnel 2 will increase, and it should be stopped in time to prevent the funnel 2 from being filled and overflowing. However, if the urine is stopped from being discharged into the funnel 2 too early, the urine retained in the funnel 2 is too little, which may result in insufficient urine even if all the urine in the funnel 2 flows into the sampling tube 1 later. In order to remind the patient to stop urinating into the funnel 2 in time, ensure that the amount of urine entering the urine specimen sampler is sufficient, and prevent the urine from overflowing the funnel, the funnel 2 preferably includes a funnel partition 22, and the funnel partition 22 is arranged in the funnel body 21. The funnel partition 22 divides the internal space of the funnel body 21 into a specimen urine space 211 and a waste urine space 212. The specimen urine space 211 is connected to the first funnel tube 23. The volume of the specimen urine space 211 is 10mL, and the upper edge of the funnel partition 22 is lower than the upper edge of the funnel body 21.

[0031] When urine fills the specimen urine space 211, it overflows from the upper edge of the funnel partition 22 and flows into the waste urine space 212. At this time, urine discharge into the funnel 2 is stopped, which can prevent the funnel 2 from overflowing when full of urine and ensure that the urine volume is sufficient.
