[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0020] like Figures 1-4 As shown, the negative pressure urine protein collector of this invention includes a barrel 1, a negative pressure suction device 2, and a rotary stirring device 3.

[0021] The top of the barrel 1 has a top wall 101 on one side and an opening on the other side. The top wall 101 is hinged to a flip cover 102, which covers the opening. A receiving cavity 103 is provided on the upper side of the top wall 101. The negative pressure suction device 2 includes a suction tube 201, a needle 203, and a vacuum test tube 206. The upper end of the suction tube 201 is located on the lower side of the top wall inside the receiving cavity 103, and the other end of the suction tube 201 extends into the lower part of the barrel 1. The needle 203... 03 is connected to the upper end of the suction tube 201 via the flexible tube 202. The needle 203 and the flexible tube 202 are housed in the receiving cavity 103. The opening of the vacuum test tube 206 is provided with a rubber stopper 207. When aspirating urine, the needle 203 pierces the rubber stopper of the vacuum test tube 206. The rotating stirring device 3 includes a stirring shaft 301 and blades 302. The upper end of the stirring shaft 301 extends into the bottom of the inner side of the cavity of the barrel 1. The blades 302 are installed on the upper end of the stirring shaft 301. The lower end of the stirring shaft 301 is provided with a stirring drive device.

[0022] Specifically, the container 1 is used to collect the patient's 24-hour urine. Before sampling, the stirring shaft 301 of the rotating stirring device 3 is driven to rotate by the stirring drive device. The stirring shaft 301 drives the blades 302 to fully stir the urine from the bottom of the container 1. Then, the needle 203 is taken out from the receiving cavity 103 and inserted into the rubber stopper 207 of the vacuum test tube 202. Under the negative pressure in the vacuum test tube 202, the urine is drawn into the vacuum test tube 202.

[0023] Furthermore, the stirring drive device includes a coil spring 303 and a pull rope 304. A cavity 105 is provided in the bottom wall of the barrel 1. One end of the coil spring 303 is fixedly connected to the inner wall of the cavity 105, and the other end of the coil spring 303 is fixedly connected to the stirring shaft 301. One end of the pull rope 304 is fixedly connected to the stirring shaft 301 and is wound around the outside of the stirring shaft 301. The other end of the pull rope 304 extends out of the barrel 1 and is connected to a handle 305. The winding direction of the pull rope 304 is opposite to the bias direction of the coil spring 303 on the stirring shaft 301.

[0024] Specifically, since one end of the pull rope 301 is wound around the outside of the stirring shaft 301, when the pull rope 304 is pulled by the handle 305, the stirring shaft 301 drives the blade 302 to rotate, stirring the urine. At the same time, the coil spring 303 is tensioned. When the pull rope 304 is unloaded, the stirring shaft 301 rotates in the opposite direction under the bias force of the coil spring 303, continuing to stir the urine. At the same time, the pull rope 304 is rewound around the outside of the stirring shaft. Repeating the pull several times can fully stir the urine.

[0025] Furthermore, a spacer plate 306 is provided on the outer side of the stirring shaft 301 between the winding point of the pull rope 304 and the connection point of the coil spring 303.

[0026] Specifically, the partition plate 306 can separate the pull rope 304 and the coil spring 303 to prevent interference between the pull rope 304 and the coil spring 303.

[0027] Furthermore, a through hole is provided between the inner cavity of the barrel 1 and the cavity 105, the stirring shaft 301 passes through the through hole, and a sealing ring 106 is provided on the inner wall of the through hole.

[0028] Specifically, the sealing ring 106 can prevent urine from leaking out from the connection between the stirring shaft 301 and the tank body 1.

[0029] Furthermore, the needle 203 is covered with a rubber sleeve 204, and a plastic protective sleeve 205 is provided outside the rubber sleeve 204.

[0030] Specifically, when removing the needle 203, the plastic protective sleeve 205 provides protection. After removing the plastic protective sleeve 205, the rubber sleeve 204 prevents fingers from being pricked by the needle 203. When the needle 203 with the rubber sleeve 204 is inserted into the vacuum test tube 206, the needle 203 can pierce through the rubber sleeve 204 and the rubber stopper 207 into the vacuum test tube 206. When the needle 203 is pulled out, the rubber sleeve 207 covers the outside of the needle 203 again. The rubber sleeve 204 prevents air from entering when the needle 203 is stored, keeping air inside the suction tube 201. When collecting urine, urine will not enter the suction tube 201, preventing unstirred urine from affecting the sample.

[0031] Furthermore, a handle 108 is provided on one side of the barrel body 1.

[0032] Specifically, a handle 108 is provided to facilitate the handling of the bucket 1. Male patients can directly hold the handle 108, open the flip cover 102, and urinate into the bucket 1. After urinating, the flip cover 102 is closed to reduce the escape of urine odor.

[0033] Furthermore, the needle 203 is a plastic needle.

[0034] Specifically, the plastic needle 203 can pierce the rubber sleeve 204 and the rubber stopper 2021, and can prevent fingers from being pricked during operation.

[0035] Furthermore, a protective film 104 is provided outside the receiving cavity 103.

[0036] Specifically, the protective film 104 is attached to the receiving cavity 103 so that the needle 203 and the vacuum test tube 206 can be stored under the protective film 104. When it is necessary to aspirate urine, the protective film 104 is torn open and the needle 203 is taken out.

[0037] In use, 24-hour urine is first collected in the container 1. The patient can open the flip-top 102 to urinate directly into the container 1, or first connect the urine to a urinal and then pour the urine from the urinal into the container 1. When the container 1 is placed, the flip-top 102 can be closed to reduce the escape of urine odor. Before sampling, the handle 305 is pulled repeatedly to fully stir the urine by rotating the stirring device 3. During sampling, the protective film 104 is first to be torn off and the needle 203 is taken out. The plastic protective sleeve 205 is removed, and then the needle 203 with the rubber sleeve 204 is inserted into the rubber stopper 207 of the vacuum test tube 202. The needle 203 pierces through the rubber sleeve 204 and the rubber stopper 207 into the vacuum test tube 202. The negative pressure in the vacuum test tube 206 draws the urine into the vacuum test tube 206. Finally, the needle 203 is pulled out, and the needle hole of the rubber stopper 207 automatically closes to prevent urine from flowing out, thus completing the sampling.
