Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, and specifically refers to a device that integrates urine sample collection, storage and measurement. Background Art
[0002] Urine collection devices are used to collect and preserve urine samples, and are widely used in medical diagnosis, drug efficacy monitoring, and disease screening. Their primary purpose is to improve the standardization and convenience of urine sample collection, reduce human error, and ensure the accuracy and reliability of the samples. By continuously optimizing the design and material selection of urine collection devices, the comfort and convenience of urine collection can be improved, while reducing the risk of contamination and cross-infection, thus contributing to the accuracy and reliability of clinical diagnosis and research.
[0003] Traditional urine collection methods typically use disposable plastic cups, which have several drawbacks, such as the risk of overflow leading to environmental and personal contamination, and the potential for cross-infection during the collection process. Furthermore, when patients collect urine themselves, the sample may be insufficient or overflowing due to excessive or insufficient urination. Doctors then need to change containers to measure the required amount of urine, which not only increases workload and wastes time but also increases the risk of cross-infection during container changes. Utility Model Content
[0004] This invention provides a device that integrates urine sample collection, storage, and measurement, solving the problems in the background art where traditional urine sampling is prone to overflow causing environmental and physical pollution, or may lead to cross-infection during the collection process, and where doctors need to measure repeatedly, increasing workload and wasting time.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A device integrating urine sample collection, storage, and measurement, comprising:
[0007] A liquid collecting tube is provided with a receiving cavity. One end of the liquid collecting tube is provided with a first opening, which communicates with the receiving cavity. The other end of the liquid collecting tube is provided with a bottom surface. The tube wall of the liquid collecting tube can undergo elastic deformation.
[0008] The sampling rod includes a sampling handle, a drip tube, a connecting rod, and a sampling swab. The sampling handle has a first end connector and a second end connector. The drip tube is located at the first end connector of the sampling handle. One end of the connecting rod is connected to the second end connector of the sampling handle, and the other end of the connecting rod has a disc. The sampling swab is made of a deformable absorbent material and is located on the other side of the disc on the connecting rod.
[0009] The first and second end connectors of the sampling handle are detachably connected to the first opening of the liquid collection tube and can seal the first opening. The sampling handle is connected to the drip tube.
[0010] In some embodiments, the sealing rings of the first end connector and the second end connector of the sampling handle are both interference-fitted with the first opening of the collection tube.
[0011] In some embodiments, the first end connector of the sampling handle is provided with a first sealing ring, the second end connector of the sampling handle is provided with a second sealing ring, and the first opening of the liquid collection tube is provided with a first anti-detachment ring. The first sealing ring is adapted to the first anti-detachment ring, and the second sealing ring is adapted to the first anti-detachment ring.
[0012] In some embodiments, the collection tube has a bottom end, and the inner diameter of the collection tube at the first opening is greater than the total length of the connecting rod and the second end connector, but less than the total length of the connecting rod, the second connector, and the sampling swab.
[0013] In some embodiments, the sampling handle, connecting rod, and drip tube are integrally formed, and a hollow channel is provided inside the drip tube, which connects to a channel provided inside the sampling handle. The channel extends to the bottom surface of the second end connector of the sampling handle.
[0014] In some embodiments, one end of the dropper passes through the sampling handle and extends to the end face of the second end connector of the sampling handle.
[0015] In some embodiments, the sampling handle, connecting rod, and sampling swab are arranged coaxially, while the drip tube is arranged eccentrically with it.
[0016] In some embodiments, the sampling swab has a cylindrical structure, and the outer diameter of the sampling swab is smaller than the inner diameter of the collection tube opening.
[0017] In some embodiments, the sampling handle is provided with a friction groove, and the stripe direction of the raised friction stripe corresponding to the friction groove is perpendicular to the force direction of the sampling handle.
[0018] In some embodiments, when the second end connector of the sampling handle seals the first opening of the collection tube, the sampling swab at the bottom of the collection tube interacts with and is squeezed and deformed by the disc of the sampling rod.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This application, by setting up a collection tube and a sampling stick, can be used for urine collection, storage, and sample measurement. The tube wall of the collection tube can undergo elastic deformation, and the sampling swab is made of elastic absorbent material for easy sampling. A drip tube is set on the sampling stick, and the drip tube is connected to both ends of the sampling handle. The two ends of the sampling handle are detachably connected to the first opening of the collection tube, which allows for the conversion between sample collection and storage. When the sampling swab with collected sample is inserted into the collection tube, the disc of the sampling stick interacts with the bottom surface of the collection tube, and the sampling swab is squeezed and deformed, and the sample is squeezed out of the sampling swab. The inverted device makes the drip tube face the ground, and the collection tube body can be squeezed by hand to drip the collected urine through the drip tube, which is convenient for accurate sample measurement. At the same time, the sampling swab with urine is stored in the collection tube, which is convenient for sample storage and avoids cross-contamination.
[0021] Additional aspects and advantages of this application will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.
[0029] like Figure 1 As shown, this utility model provides a device that integrates urine sample collection, storage and measurement, mainly including a collection tube 2 and a collection rod, wherein the collection rod is detachably mounted on the collection tube 2.
[0030] Specifically, if Figure 2 As shown, the collecting tube 2 has a receiving cavity 21, and one end of it has a first opening 22 that connects to the receiving cavity 21. The wall of the collecting tube 2 can undergo elastic deformation; that is, when the wall of the collecting tube 2 is compressed by an external force, the wall of the collecting tube 2 will deform, and the space of the receiving cavity 21 will shrink. When the external force is removed, the size of the wall of the collecting tube 2 and the receiving cavity 21 will return to their initial state. For example, the collecting tube 2 can be made of an elastomer rubber material or plastic, and it is easy to observe. The wall of the collecting tube 2 is generally transparent and visible.
[0031] The sampling rod includes a sampling handle 1, a drip tube 3, a connecting rod 13, and a sampling swab 14. The sampling handle 1 has a first end connector 11 and a second end connector 12. Both the first end connector 11 and the second end connector 12 can be adapted to the first opening 22 of the collection tube 2 and can seal the first opening 22. In this embodiment, both the first end connector 11 and the second end connector 12 are boss structures, such as cylindrical bosses, and both the first end connector 11 and the second end connector 12 are interference-fitted with the first opening 22. Furthermore, to enhance the sealing performance, a sealing ring can be provided on the first end connector 11 and the second end connector 12. When the first end connector 11 or the second end connector 12 is positioned at the first opening 22, the sealing ring is compressed, thereby achieving better sealing performance.
[0032] A dropper 3 is disposed on the sampling handle 1, connecting the first end connector 11 and the second end connector 12. A connecting rod 13 is disposed on the second end connector 12 of the sampling handle 1. A disc 132 is disposed at the end of the connecting rod 13 away from the sampling handle 1. A sampling swab 14 is fixed on the other side of the disc. The sampling swab 14 is made of a deformable, highly absorbent material, such as a sponge or cotton ball. In this embodiment, a sponge is preferred because it has a large absorbency and is easy to squeeze out. When the sampling swab 14 is squeezed by external force, the sample will be squeezed out of the sampling swab 14. When the device is inverted, the dropper 3 faces the ground. Because the first end connector 11 and the second end connector 12 are connected, the squeezed sample drips out through the dropper 3, which facilitates accurate sample measurement by the doctor.
[0033] In this embodiment, as Figure 5 As shown, when taking samples, the first end connector 11 of the sampling handle 1 is fixed to the first opening 22 of the collection tube 2, making it easy for the sampler to grip. Simultaneously, considering the length of the collection tube 2, compared to traditional sampling structures, the length between the sampling swab 14 and the sampler's grip is increased, preventing sample from getting on their hands. This also reduces the length of the connecting rod 13, decreasing the overall size of the device. By using a highly absorbent sampling swab 14, the sample is fully absorbed. After sampling, the sampler removes the first end connector 11 of the sampling handle 1 from the first opening 22, fixes the second end connector 12 of the sampling handle 1 to the first opening 22, and places the sample-laden sampling swab 14 into the receiving cavity 21 of the collection tube 2. Figure 6 As shown, this device is used for independent storage of samples, avoiding cross-contamination. During insertion, because the total length of the second end connector 12 of the connecting rod 13 is slightly less than the depth of the collection tube 2 from the first opening 22 to the bottom 23, and the depth of the collection tube is less than the total length of the second end connector 12 of the connecting rod 13 of the sampling swab 14, the sample liquid will be squeezed out of the sampling swab 14 due to the interaction between the disc 132 and the bottom 23 of the collection tube 2. When sample testing is required, the doctor only needs to invert the device with the drip tube 3 facing the ground and squeeze the wall of the collection tube 2 by hand. The sample liquid will flow from the channel opening 131 through the channel 15 and into the drip tube 3 due to the increased internal pressure, allowing the user to perform accurate sample collection.
[0034] In one embodiment, to facilitate the detachable connection between the first end connector 11 and the second end connector 12 of the sampling handle 1 and the collection tube 2, a first sealing ring 111 is provided at the first end connector 11 of the sampling handle 1, a second sealing ring 121 is provided at the second end connector 12 of the sampling handle 1, and a first anti-detachment ring 23 is provided at the first opening 22 of the collection tube 2. The first sealing ring 111 and the first anti-detachment ring 23 are adapted to each other, and the second sealing ring 121 and the first anti-detachment ring 23 are also adapted. In actual operation, the sampler only needs to forcefully insert the second sealing ring 121, which will engage with the first anti-detachment ring 23 to secure it. When it needs to be removed, because the collection tube 2 is elastic, the sampling handle 1 can be removed simply by rotating and prying it off.
[0035] In one embodiment, to facilitate user sampling, the collection tube 2 is provided with a bottom end 23, the inner diameter of which is smaller than the inner diameter of the first opening 22 of the collection tube 2. When the second end 12 of the sampling handle 1 is fixed at the first opening 22, the sampling swab 14 is located at the bottom end 23 of the collection tube 2, reducing the deformation space of the sampling swab. This allows the sampling swab 14 to be squeezed more fully, thus squeezing out more sample liquid.
[0036] Optionally, the shape of the sampling swab 14 is not limited by this utility model, and can be a prism or frustum structure, etc.
[0037] In one embodiment, to simplify the structure of the sampling rod, the optimal implementation method is as follows: Figure 2 As shown, the sampling handle 1 and the connecting rod 13 are integrally formed. A channel opening 131 is provided at the bottom of the second end connector 12. A channel 15 is provided inside the sampling handle 1. A hollow channel is provided inside the drop tube 3. The channel 15 extends to the bottom surface of the second end connector 12 of the sampling handle 1. The hollow channel connects the channel 15 to the bottom channel opening 131 of the second end connector 12, thereby forming a structure in which one end of the drop tube 3 passes through the sampling handle 1 and extends to the end face of the second end connector 12 of the sampling handle 1, which facilitates sample drop.
[0038] Furthermore, to reduce the overall size of the sampling device, in this embodiment, the sampling handle 1, connecting rod 13, disc 132, and sampling swab 14 are arranged coaxially, such as... Figure 2 As shown, when the sampling handle 1 is inserted into the collection tube 2, the center of the sampling swab 14 coincides with the center of the sampling handle 1. In addition, after sampling, in order to avoid contaminating the user's hand and to facilitate operation, the diameter of the first opening 22 of the collection tube 2 is larger than the diameter of the sampling swab 14.
[0039] In one embodiment, to increase the friction between the sampler's hand and the sampling handle 1, friction grooves are provided on the sampling handle. The direction of the raised stripes corresponding to the friction grooves is perpendicular to the direction of action of the sampling handle, maximizing the friction between the sampler's hand and the sampling handle. In this embodiment, multiple friction grooves are provided on the surface of the sampling handle. Optionally, multiple protrusions can also be provided on the surface of the sampling handle.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
