Description

Technical Field

[0001] The utility model relates to the technical field of detection sample extraction, in particular to a quantitative sampling device for rapid urine sampling in gene detection. Background Art

[0002] Detecting genes through urine is a commonly used detection method. Since gene detection requires multiple steps and the amount of urine required for each step is different, and traditional urine extraction methods cannot accurately quantify, it is extremely easy to cause a shortage or excess of samples, and it is necessary to re-extract samples or process the excess urine, which is not only unhygienic but also very troublesome. Therefore, a quantitative sampling device for rapid urine sampling is needed to solve the problem.

[0003] Chinese Patent CN215574056U discloses a quantitative extraction device for urine samples in gene detection, including a collection cylinder. The top of the collection cylinder is threadedly connected with a sleeve. The side wall of the collection cylinder is engraved with scale lines. The top of the sleeve is welded with a collection cover. A pressing component is slidably connected to the side wall of the sleeve. An adjusting component is installed inside the sleeve. The pressing component is slidably connected to the side wall of the adjusting component. The adjusting component includes a fixed block, a slider, a sphere, a second spring, an inclined groove and a second chute. By setting an adjusting component inside the sleeve and controlling it through the pressing component, it is convenient to quantitatively extract urine samples according to the actual situation.

[0004] The above solution still has several improvement points: Urine will remain on the funnel and contact the air and deteriorate. When pouring the sample in the bottle during detection, it will be mixed with the deteriorated sample, affecting the accuracy of the result; It can only accurately quantify when collecting urine and cannot accurately quantify when discharging the sample.

Detailed implementation manners

[0025] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0026] See Figures 1 to 7 As shown, a quantitative sampling device for rapid urine sampling for gene detection includes a collection bottle 1, a sampler 2 for accurate quantitative sampling, a sealing cover 7 for closing the collection bottle 1, and a funnel 8 for facilitating urine collection. The sampler 2 includes a metering tube 3 for quantification, a sampling tube 4 for sampling, a sample discharge tube 5 for discharging urine, and a ball valve 6. The sealing cover 7 is installed on the top of the collection bottle 1, the funnel 8 is installed on the upper surface of the sealing cover 7, the sampling tube 4 is installed at the bottom of the sampler 2 and obliquely inserted into the collection bottle 1, the metering tube 3 is installed at the top of the sampler 2 and corresponds to the position of the sampling tube 4, the sample discharge tube 5 is installed at the top of the sampler 2 and communicated with the metering tube 3, and the ball valve 6 is installed on the sampling tube 4.

[0027] The sampling device uses a funnel 8 to collect urine and then rotates the cover 7 to seal the interior of the collection bottle 1 to prevent the urine from volatilizing and deteriorating due to long-term contact with air. Then, the sampler 2 is inserted into the collection bottle 1 for quantitative sampling. The sampling tube 4 is inserted into the collection bottle 1 at an angle to ensure that the sampler 2 can drain the urine in the bottle. Then, the ball valve 6 is opened to sample the urine. By setting a scale on the surface of the measuring tube 3, the unit amount of urine required for quantitative measurement can be accurately measured to ensure the accuracy of sampling and discharge. When discharging the sample, the ball valve 6 is first closed to disconnect the connection between the sampling tube 4 and the measuring tube 3, and the extracted urine will be discharged from the discharge tube 5.

[0028] See also Figure 3 and Figure 4 As shown, the metering tube 3 is provided with a ring frame 31, a tube cover 32, a flow hole 33 and a pull rod 34. The tube cover 32 is installed at one end of the metering tube 3, the ring frame 31 is fixed on one side of the metering tube 3 close to the tube cover 32, the flow hole 33 array is arranged on the tube cover 32 and the ring frame 31, and the pull rod 34 is installed at the center of the metering tube 3.

[0029] The flow hole 33 ensures that urine can normally enter the measuring tube 3 from the sampling tube 4 during sampling. The ring frame 31 is used to seal the tube cover 32 during urine discharge so that urine can be discharged from the sampling tube 5. The pull rod 34 is pulled to form an air pressure difference in the measuring tube 3 to complete the sampling measurement.

[0030] See also Figure 4 As shown, a first spring 311 and a sealing ball 312 are provided on the ring frame 31 , one end of the first spring 311 is connected to the outside of the flow hole 33 , and the other end is connected to the sealing ball 312 .

[0031] When sampling, the pull rod 34 is pulled, and the sealing ball 312 squeezes the first spring 311 to ensure that the flow hole 33 on the tube cover 32 is opened. When discharging samples, the pull rod 34 is pushed, and the sealing ball 312 is squeezed by the first spring 311 to block the flow hole 33 on the tube cover 32 to prevent urine from flowing back into the collection bottle 1.

[0032] See also Figure 2 and Figure 3 As shown, the pull rod 34 is provided with a piston 341 , a handle 342 and a second spring 343 . The piston 341 is installed at one end of the pull rod 34 , the handle 342 is installed at the other end of the pull rod 34 , and the second spring 343 is surrounded on the outside of the pull rod 34 .

[0033] The piston 341 is used to increase the air pressure difference generated when the pull rod 34 is pulled, the handle 342 facilitates manual pushing and pulling of the pull rod 34, and the second spring 343 is used to slow down the displacement of the pull rod 34 to avoid damage to the metering tube 3 caused by rapid pushing and pulling of the pull rod 34.

[0034] See also Figure 3As shown, a transfer pipeline 51, a check valve 52, and a connecting pipe 53 are provided on the sample discharging pipe 5. The transfer pipeline 51 is arranged in the sampler 2 and connects the sample discharging pipe 5 and the metering pipe 3. The check valve 52 is arranged in the sample discharging pipe 5, and the connecting pipe 53 is installed at the top of the sample discharging pipe 5.

[0035] The transfer pipeline 51 connects the sample discharging pipe 5 and the metering pipe 3. When sampling, the check valve 52 closes the transfer pipeline 51 to prevent urine from directly entering the sample discharging pipe 5 from the sampling pipe 4. When discharging the sample, the check valve 52 opens, and urine normally enters the connecting pipe 53 from the sample discharging pipe 5 to complete quantitative sampling.

[0036] See Figures 3 to 5 As shown, a top ball 521, a third spring 522, and a positioning rod 523 are provided on the check valve 52. The positioning rod 523 is installed inside the sample discharging pipe 5. One end of the third spring 522 is connected to the positioning rod 523, and the other end is connected to the top ball 521.

[0037] The positioning rod 523 is used to install the check valve 52. The top ball 521 is used to control the opening and closing of the check valve 52. When discharging the sample, the top ball 521 is pushed away from the valve port of the check valve 52 by air pressure, and the third spring 522 is stretched. When sampling, the air pressure difference generated by the push rod and the reset tension of the third spring 522 cause the top ball 521 to firmly seal the sample discharging pipe 5.

[0038] See Figures 2 to 6 As shown, a switch 61, a rotating shaft 62, and a rotating cover 63 are provided on the ball valve 6. The rotating cover 63 is rotatably installed at the center of the ball valve 6. One end of the rotating shaft 62 is fixed to the rotating cover 63, and the other end is fixed to the switch 61.

[0039] The switch 61 rotates to rotate the rotating shaft 62, thereby controlling the degree of fit between the rotating cover 63 and the ball valve 6. When the rotating cover 63 is completely fitted with the ball valve 6, the ball valve 6 closes and disconnects the flow of urine in the sampling pipe 4.

[0040] See Figure 7 As shown, a through hole 71, a fitting layer 72, a sliding groove 73, and a key 74 are provided on the sealing cover 7. The fitting layer 72 is rotatably installed in the sealing cover 7. The through holes 71 are arranged in an array on the sealing cover 7 and the fitting layer 72. The sliding groove 73 is opened on the side of the sealing cover 7. The key 74 is fixedly connected to the fitting layer 72 and is located in the sliding groove 73.

[0041] The through hole 71 is used to ensure that urine can enter the collection bottle 1 from the funnel 8. By moving the key 74 in the sliding groove 73, the rotation between the fitting layer 72 and the sealing cover 7 is controlled, thereby controlling the opening and closing of the through hole 71.

[0042] The above embodiments merely represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
