Description

Technical Field

[0001] This utility model relates to the field of urine collection technology, specifically to a urine collection device for urine detection. Background Technology

[0002] As a routine clinical test, the convenience and reliability of the sample collection device directly affect the accuracy of the test results. Traditional urine collection devices mostly use a single-channel open container structure, which is inconvenient to operate and prone to sample contamination when it is necessary to collect urine samples in segments at different stages.

[0003] Especially when collecting urine in segments, patients often lack experience or operate improperly, making it difficult to collect urine in segments. Existing urine collection devices not only increase the difficulty of operation but also pose a risk of secondary contamination from hand contact with the sample. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution: a urine collection device, including a urine collection bucket, a hand-held block on the outside of the urine collection bucket, an installation groove on the top of the hand-held block, a pressing block movably installed inside the installation groove, a discharge pipe at the bottom of the urine collection bucket, the discharge pipe communicating with the urine collection bucket, an installation cylinder on the outside of the discharge pipe, a diversion pipe on the outside of the discharge pipe, the installation cylinder and the diversion pipe being parallel and both communicating with the discharge pipe, a collection pipe detachably installed at one end of the diversion pipe, a sealing component inside the installation cylinder, the sealing component being fitted against the inner wall of the discharge pipe, and the sealing component cooperating with the pressing block.

[0005] As a preferred embodiment of this utility model, an annular groove is provided on the outer side of the diversion pipe, and the annular groove cooperates with the protrusion on the inner side of the collection pipe.

[0006] As a preferred embodiment of this utility model, the sealing assembly includes a sealing post, a pull rod, a return spring, a pull plunger, and a rubber barrier. The sealing post is fixedly installed on the inner wall of one end of the diversion tube. The pull rod is movably installed through the sealing post. The return spring is sleeved on the outside of the pull rod located inside the diversion tube. The pull plunger is fixedly installed on the end face of the pull rod located inside the diversion tube. The rubber barrier is fixedly installed on one end of the pull plunger. The other end of the pull rod passes through the hand-held block and is fixedly connected to the bottom of the pressing block.

[0007] As a preferred embodiment of this utility model, the return spring sleeved on the outside of the pull rod is initially in a compressed state, the inner diameter of the return spring is larger than the diameter of the pull rod, and the end of the return spring near the pull plunger is fixedly connected to the surface of the pull plunger.

[0008] As a preferred technical solution of this utility model, the pull rod is composed of a metal rod and a metal wire. The metal rod is located inside the diversion tube, and the exposed part connected to the pressing block is the metal wire.

[0009] As a preferred technical solution of this utility model, the traction plunger and the rubber barrier are inclined at 120 degrees, the rubber barrier is fitted to the inner wall of the discharge pipe, and the rubber barrier is made of soft rubber and has a certain shape.

[0010] As a preferred technical solution of this utility model, the rubber barrier sheet has a rubber inclined surface on its outer side, and the rubber inclined surface is in contact with the inner wall of the discharge pipe. The rubber barrier sheet and the discharge pipe are initially in contact, thus sealing the inner wall of the discharge pipe.

[0011] Compared with the prior art, the present invention provides a urine collection device for testing, which has the following beneficial effects:

[0012] The urine testing collection device uses a press-type linkage sealing mechanism (press block - pull rod - sealing component), which can switch the flow rate of the discharge tube and the diversion tube with one hand. It can quickly switch between initial urine disposal and accurate collection of midstream urine without contacting the sample, meeting the standardized collection needs of clinical testing for segmented samples.

[0013] The urine collection device employs a dual-sealing mechanism in its sealing assembly, consisting of an inclined rubber barrier and a return spring. The tight fit between the rubber bevel and the inner wall of the discharge tube creates a physical seal when not pressed, while the pre-compression of the return spring ensures a constant return force on the plunger. Together, these two mechanisms effectively prevent urine leakage. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model discloses a urine collection device for urine testing, including a urine collection bucket 2, a hand-held block 1 on the outside of the urine collection bucket 2, an installation groove on the top of the hand-held block 1, a pressing block 3 movably installed inside the installation groove, a discharge pipe 8 at the bottom of the urine collection bucket 2, the discharge pipe 8 communicating with the urine collection bucket 2, an installation cylinder 5 on the outside of the discharge pipe 8, a diversion pipe 6 on the outside of the discharge pipe 8, the installation cylinder 5 and the diversion pipe 6 being parallel and both communicating with the discharge pipe 8, a collection pipe 7 being detachably installed at one end of the diversion pipe 6, a sealing component inside the installation cylinder 5, the sealing component being fitted against the inner wall of the discharge pipe 8, and the sealing component being used in conjunction with the pressing block 3.

[0022] When using this collection device, hold the urine collection bucket 2 by pinching the hand-held block 1, allowing urine to enter through the opening at the top of the urine collection bucket 2. Press the pressing block 3 to pull the pull rod 4 upward. At this time, the pull rod 4 will retract the sealing component, and the urine will be discharged directly from the discharge pipe 8. When the pressing block 3 is released, the sealing component that has retracted into the mounting cylinder 5 will spring back to seal the inside of the discharge pipe 8. At this time, the urine will enter the diversion pipe 6 and be discharged into the collection pipe 7 for storage.

[0023] The purpose of installing a sealing component inside the discharge pipe 8 to allow urine to be discharged in two different states is to achieve segmented collection of urine.

[0024] Specifically, an annular groove is provided on the outer side of the diversion pipe 6, and the annular groove cooperates with the protrusion on the inner side of the collection pipe 7.

[0025] In this embodiment, an annular groove is provided to engage with the protrusion on the inner side of the collection tube 7. The snap-fit ​​limiting of the collection tube 7 ensures a stable connection between the diversion tube 6 and the collection tube 7, and also ensures that urine collection will not splash out.

[0026] Specifically, the sealing assembly includes a sealing post 12, a pull rod 4, a return spring 9, a pull plunger 10, and a rubber barrier 11. The sealing post 12 is fixedly installed on the inner wall of one end of the diversion tube 6. The pull rod 4 is movably installed through the sealing post 12. The return spring 9 is sleeved on the outside of the pull rod 4 located inside the diversion tube 6. The pull plunger 10 is fixedly installed on the end face of the pull rod 4 located inside the diversion tube 6. The rubber barrier 11 is fixedly installed on one end of the pull plunger 10. The other end of the pull rod 4 passes through the handheld block 1 and is fixedly connected to the bottom of the pressing block 3.

[0027] In this embodiment, a sealing post 12 is used to install the pull rod 4. The return spring 9 works in conjunction with the sealing post 12. When the pull rod 4 is pulled, the return spring 9 is compressed by the blocking of the sealing post 12, thereby storing a certain amount of elastic potential energy, which assists in the reset of the pull plunger 10 and the rubber barrier 11. The pull plunger 10 plays the role of installing and pulling the rubber barrier 11.

[0028] Specifically, the return spring 9, which is sleeved on the outside of the pull rod 4, is initially in a compressed state. The inner diameter of the return spring 9 is larger than the diameter of the pull rod 4. The end of the return spring 9 that is close to the pull plunger 10 is fixedly connected to the surface of the pull plunger 10.

[0029] The pull rod 4 consists of a metal rod and a metal wire. The metal rod is located inside the diversion tube 6, and the exposed part that is connected to the pressing block 3 is the metal wire.

[0030] In this embodiment, a reset spring 9 is provided to pull the pull plunger 10 and the pull rod 4. When the pull rod 4 is pulled by the pressing block 3, it will compress the reset spring 9. When the pressing block 3 is released, the reset spring 9 will drive the pull plunger 10 and the pull rod 4 to reset.

[0031] Specifically, the traction plunger 10 and the rubber barrier 11 are inclined at 120 degrees. The rubber barrier 11 is fitted to the inner wall of the discharge pipe 8. The rubber barrier 11 is made of soft rubber and has a certain shape. A rubber inclined surface 13 is opened on the outer side of the rubber barrier 11. The rubber inclined surface 13 is fitted to the inner wall of the discharge pipe 8. The initial state of the rubber barrier 11 and the discharge pipe 8 is a fitted state, which seals the inner wall of the discharge pipe 8.

[0032] In this embodiment, a rubber baffle 11 is provided at one end of the pull plunger 10 to seal the inside of the discharge pipe 8, thereby intercepting the urine and achieving segmented retention. Specifically, the interception is achieved by the pull rod 4 pulling the pull plunger 10 along the inner wall of the mounting cylinder 5 to contract and separate the rubber baffle 11 from the inner wall of the discharge pipe 8, at which point the urine is directly discharged. After the pull rod 4 is released, the pull plunger 10 and the rubber baffle 11 rebound under the action of the return spring 9 and stick to the inner wall of the discharge pipe 8, thereby intercepting the urine and allowing the urine to be discharged through the diversion pipe 6 to the collection pipe 7 for storage.
