Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel urine collection tube for laboratory use. Background Technology
[0002] Currently, urine analysis is a crucial step in assessing a patient's health status during medical diagnosis. Traditional urine collection methods largely rely on patients pouring urine into the collection tube themselves. This method is prone to sample contamination due to improper operation and may also affect sample integrity due to patient inconvenience. With advancements in medical technology and increasing patient demand, there is an urgent need for a new type of urine collection tool that effectively avoids sample contamination, simplifies the collection process, and improves the patient experience. For example, Chinese Patent Publication No. CN216284517U discloses a urine collection device for a laboratory, comprising a collection tube and a collection bucket. The collection bucket is fixedly connected to the top of the collection tube. A nozzle is located on one side of the collection bucket and is fixedly connected to it. A groove is located inside the nozzle. A protective ring is located on the outer surface of the inner side of the collection bucket and is fixedly connected to it. An outlet tube is fixedly connected to one side of the lower end of the collection tube.
[0003] While some collection tubes offer sealing caps, the seals are often ineffective, leading to sample leakage during transport or storage. Furthermore, most collection tubes lack effective urine aspiration mechanisms, requiring patients or healthcare professionals to directly empty the urine, increasing the risk of contamination. Therefore, developing a novel urine collection tube that allows for easy urine aspiration while ensuring sample sealing and ease of operation is crucial. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a new type of urine collection tube for the laboratory, which solves the technical problems of inconvenient operation and insufficient sample sealing of existing urine collection tubes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel urine collection tube for laboratory use, comprising a tube body with an opening and a cap disposed at the opening of the tube body. At least one perforated portion is provided at the upper end of the cap. A rubber stopper is abutted against the inner wall of the middle portion of the cap. A stepped portion is formed on the side of the rubber stopper. A connecting mounting hole is provided at the center of the rubber stopper, and a vertically extending suction tube is disposed at the connecting mounting hole. A hollow rubber sphere is disposed inside the cap at the upper end of the rubber stopper. The hollow rubber sphere communicates with the connecting mounting hole. The side portion of the rubber sphere protrudes from the perforated portion. When the cap and tube body are engaged, the stepped portion abuts against the inner wall of the opening of the tube body, and the cap abuts against or is threadedly connected to the outer wall of the tube body.
[0006] Furthermore, a locking through hole is provided at the middle of the upper end of the cover, and a locking protrusion is provided on the rubber ball to be fastened to the locking through hole.
[0007] Furthermore, a recessed groove is provided inside the locking through hole, and a protruding retaining ring is provided on the locking protrusion, the protruding retaining ring being locked inside the recessed groove.
[0008] Furthermore, an elastic support ring is provided at the middle of the inner wall of the rubber ball to enhance the elasticity of the rubber ball when it pops outward.
[0009] Furthermore, the upper end of the rubber plug is provided with a first clamping part, and the lower end of the rubber ball forms a clamping opening. The edge of the clamping opening is clamped in the first clamping part and forms a seal.
[0010] Furthermore, the clamping opening is bent inward to form a clamping ring, and a sealing protrusion is provided on the inner side of the clamping ring. The first clamping part includes a clamping channel that cooperates with the clamping ring and a sealing groove that cooperates with the sealing protrusion.
[0011] Furthermore, the clamping channel is curved.
[0012] Furthermore, a sealing ring is provided on the inner side of the cover and at the stepped portion of the rubber plug, and a second clamping portion for clamping the opening of the tube is formed between the sealing ring and the stepped portion of the rubber plug.
[0013] Furthermore, the lower end of the sealing ring has an inclined guide surface to guide the cap into the opening of the tube.
[0014] Furthermore, the outer wall of the upper end of the tube is an inclined clamping surface, which is inclined from bottom to top and from the center outward.
[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0016] 1. This solution utilizes a tube with an opening and a cap located at the opening. The cap has a perforated upper part and a rubber stopper on its inner wall. The rubber stopper contains a pipette, a connecting hole, and a hollow rubber ball connected to it. By squeezing the rubber ball, urine can be drawn up using the pipette and injected into the tube. This simplifies the urine collection process and avoids the contamination risk associated with directly pouring urine. Simultaneously, the design of the rubber stopper and rubber ball enhances the sealing of the collection tube, effectively preventing sample leakage and improving the reliability and safety of the collection tube.
[0017] 2. A locking through-hole is made in the middle of the upper end of the cover, and a locking protrusion is provided on the rubber ball to secure it to the locking through-hole, thereby fixing the rubber ball in place. This effectively prevents the rubber ball from shifting or falling off, improves the stability and service life of the collection tube, and ensures the smooth progress of the collection process.
[0018] 3. A recessed groove is provided within the locking through hole, and a raised retaining ring is provided on the locking protrusion. The raised retaining ring is locked within the recessed groove to achieve a tighter fit. This enhances the connection stability between the locking protrusion and the locking through hole, effectively improving the reliability of the connection.
[0019] 4. The elastic support ring enhances the elasticity of the rubber ball, resulting in more even and sufficient force when absorbing urine, thus improving collection efficiency.
[0020] 5. The design of the first clamping part and the clamping opening enhances the tightness of the connection between the rubber ball and the connecting mounting hole, effectively preventing sample leakage and improving the sealing and safety of the collection tube. Furthermore, the opening bends inward to form a clamping ring, and a sealing protrusion is provided on the inner side of the clamping ring. The first clamping part includes a clamping channel that mates with the clamping ring and a sealing groove that mates with the sealing protrusion, further improving the tightness of the sealing structure and ensuring that the collection tube maintains a good sealing effect even under prolonged use or improper operation, avoiding the risk of sample leakage. The optimized design of the clamping channel improves the sealing effect.
[0021] 6. The sealing ring design, with its stepped sections forming a second clamping part between the rubber stopper body, enhances the seal between the cap and the tube, effectively preventing leakage risks during sample transportation or storage and improving the reliability and safety of the collection tube. The lower end of the sealing ring is designed with an incline, guiding the cap into the tube opening, simplifying the cap installation process, reducing installation difficulty, and improving operational convenience. Furthermore, the incline of the upper outer wall of the tube provides a locking effect when the cap and tube are engaged; the incline angle can be set from 1 to 3 degrees. Attached Figure Description
