What does a urine sediment test tube look like? Clinically, urine tests are an important means of diagnosing urinary tract diseases and bodily functions. Before urine collection, medical personnel usually distribute urine collection cups and open-top test tubes for patients to collect themselves, then pour them into open-top test tubes for testing. Currently, the use of such open-top test tubes for urine collection has the following problems: firstly, the diameter of the open-top test tube is too small, making it difficult to pour urine from the urine collection cup into the test tube; secondly, when pouring, urine is easily spilled on the outer wall of the open-top test tube, and the urine spilled on the outer wall of the open-top test tube easily flows quickly to the patient's hands; thirdly, there is a distance between the bathroom and the laboratory. Within this distance, the urine in the open test tube is completely exposed to the air, and bacteria in the air often contaminate the urine.

　　A urine sediment test tube is a urine test tube that facilitates collection, prevents urine from dripping onto the patient's hands, and prevents urine samples from being contaminated. It includes a test tube body, and the top of the test tube body is provided with an opening; the test tube body is divided into an introduction part and a hand-held part, the introduction part is located at the upper part of the test tube body, and the hand-held part is located at the lower part of the test tube body; the diameter of the introduction part is larger than the diameter of the hand-held part; the urine test tube also includes a sealing device and a retaining ring, the retaining ring is a ring with a diameter larger than the outer diameter of the introduction part, and the inner ring of the retaining ring is fixed to the outer wall of the hand-held part; the sealing device includes a sealing cap, a fixing band, and a snap ring; a circular groove is provided on the outer wall of the hand-held part along the circumferential direction, and the snap ring is rotatably set in the circular groove, the inner wall of the sealing cap is threadedly connected with the outer wall of the introduction part, and the fixing band is connected between the sealing cap and the snap ring.

　　Multiple hand-held grooves are provided on the outer wall of the hand-held part of the urine sediment test tube, allowing the patient to grasp the hand-held grooves, which facilitates holding the test tube body and prevents the test tube body from slipping.

　　A circular groove is provided on the outer wall of the hand-held part above the snap ring of the urine sediment test tube, which reduces the wear of the fixing band and makes it easier to tighten the sealing cap.

　　Scales are provided on the outer walls of the introduction part and the hand-held part of the urine sediment test tube for easy reading.

　　In addition, multiple vertically open U-shaped grooves are provided around the periphery of the sealing cap of the urine sediment test tube to increase friction and prevent the sealing cap from slipping during tightening.

　　The urine sediment test tube facilitates pouring urine from the urine collection cup into the test tube; the retaining ring is a ring with a diameter larger than the outer diameter of the introduction part, and the inner ring of the retaining ring is fixed to the outer wall of the hand-held part, which can prevent urine from dripping onto the patient's hands and maintain hygiene; the snap ring of the urine sediment test tube is rotatably set in the circular groove; the inner wall of the sealing cap is threadedly connected with the outer wall of the introduction part; the fixing band connects the sealing cap and the snap ring.

　　At the same time, after the urine is poured out, it can be sealed with a sealing cap to prevent the urine sample from being contaminated; at the same time, the sealing cap is fixed to the test tube body by a fixing band and a snap ring, which is not easy to lose and is convenient to use.
