Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a foldable 24-hour urine collection device. Background Technology

[0002] For patients with kidney disease or kidney damage caused by hypertension, a more comprehensive and accurate urine test, such as 24-hour urine analysis, is required. A 24-hour urine test requires the continuous collection of all urine over 24 hours and the testing of multiple indicators.

[0003] Chinese Patent Publication No. CN221865767U discloses a 24-hour urine sample collection device, including a cup body and a receiving container. The cup body has an internal cavity with an open upper end. The receiving container is connected to the cup body at its lower end, which can close the upper opening of the cup body. The receiving container includes a conical body, a flip cover, and a torsion spring. The conical body has openings at both ends, and a pivot is provided at the smaller end. One end of the flip cover is sleeved on the pivot and hinged to the conical body, which can close or open the smaller opening of the conical body. The torsion spring is sleeved on the pivot, and its two ends are connected to the flip cover and the conical body, respectively. The device is closedly connected to the cup body through the receiving container, and the flip cover, which can close or open the smaller opening of the conical body, is hinged to one end of the conical body. Under the action of the torsion spring, the flip cover automatically opens when collecting urine, and closes at other times to prevent odors from escaping from the cavity, so as not to cause inconvenience to the patient or others. It is suitable for use when going out or at work. However, the above-mentioned device has the following drawbacks in use: the device is usually for single use, the demand is large, and because it needs to store urine for 24 hours, the cup is large in size. The rigid material makes the transportation and storage process inconvenient. Although it is convenient to transport if a retractable bag is used to collect urine, the bag lacks protection and is easily damaged, and the bag has poor support. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing 24-hour urine collection devices use rigid containers to collect urine. These containers are large and non-foldable, causing inconvenience during transportation and storage. Foldable bags, lacking protection, have been damaged. To address this problem, a foldable 24-hour urine collection device is proposed, comprising a disposable collection mechanism and a support. The collection mechanism is mounted on the support. The collection mechanism includes an upper support, a corrugated pipe, and a lower support. The upper support is connected to the opening of the corrugated pipe, and the lower support is connected to the bottom of the corrugated pipe. The upper and lower support are detachably connected. A drain valve is installed at the bottom of the lower support, communicating with the inner cavity of the corrugated pipe.

[0005] The technical solution of this utility model, through the structure of an upper support base, a corrugated pipe, and a lower support base, allows the corrugated pipe to be folded, thereby reducing its volume and facilitating transportation and storage. At the same time, the upper support base and the lower support base are connected by a snap-fit ​​mechanism, which allows the corrugated pipe to be completely retracted between the two. The upper and lower support bases protect the corrugated pipe from damage during transportation. When needed, the upper and lower support bases are separated, and the corrugated pipe automatically unfolds, making it convenient to use.

[0006] In a preferred embodiment of the present invention, the upper part of the upper support is provided with an openable top cover, which is hinged to the upper support. A handle is provided on the end face of the top cover away from the hinge point. Opening the top cover facilitates the entry of urine into the corrugated pipe for urine collection, and the handle facilitates opening or closing the top cover.

[0007] In a preferred embodiment of the present invention, the top cover is located directly above the opening of the corrugated pipe, and the top cover can be directly connected to the inner cavity of the corrugated pipe after it is opened.

[0008] In a preferred embodiment of the present invention, a locking block is provided at the lower part of the upper support base. The locking block has a circular cross-section. The inner wall of the locking block is connected to the corrugated pipe, and the outer wall of the locking block is fitted to the lower support base. The inner wall of the locking block is used for bonding and fixing with the corrugated pipe, and the outer wall of the locking block is the engaging surface with the lower support base, which is in close contact with the inner wall of the lower support base.

[0009] In a preferred embodiment of the present invention, the diameter of the upper support seat is greater than the maximum diameter of the card block, so the upper support seat can be connected to the bracket to support and fix the collecting mechanism.

[0010] In a preferred embodiment of the present invention, the upper part of the corrugated pipe is a connecting part, and the outer wall of the connecting part is smooth, which facilitates bonding and fixing with the inner wall of the card block.

[0011] In a preferred embodiment of the present invention, the maximum diameter of the corrugated tube when folded is smaller than the maximum diameter of the locking block, and scale lines are provided on the outer wall of the corrugated tube. Therefore, when the corrugated tube is folded and stored, it is not easily damaged by other structures, and the scale lines facilitate the judgment of urine volume.

[0012] In a preferred embodiment of the present invention, the lower support portion is dish-shaped, and the inner wall of the lower support portion is provided with a slot that matches the locking block. The dish shape facilitates the storage of the corrugated pipe, and the locking block and the slot are fitted with an interference fit.

[0013] In a preferred embodiment of the present invention, the bracket includes a circular clamp and multiple legs. The legs are evenly arranged on the clamp and are inclined outwards. The clamp is used to hold the collection mechanism, and the outward inclination of the legs provides more stable support.

[0014] In a preferred embodiment of the present invention, the diameter of the clamp is greater than the maximum diameter of the clamp block, and the diameter of the clamp is less than the diameter of the upper support base. The collecting mechanism can be placed into the clamp from top to bottom, and then the clamp is made to fit against the lower surface of the upper support base to support the collecting mechanism.

[0015] The advantages of this utility model compared with the prior art are: The technical solution of this utility model, through the structure of an upper support base, a corrugated pipe, and a lower support base, allows the corrugated pipe to be folded, thereby reducing its volume and facilitating transportation and storage. At the same time, the upper support base and the lower support base are connected by a snap-fit ​​mechanism, which allows the corrugated pipe to be completely retracted between the two. The upper and lower support bases protect the corrugated pipe from damage during transportation. When needed, the upper and lower support bases are separated, and the corrugated pipe automatically unfolds, making it convenient to use. Attached Figure Description

Detailed Implementation

[0017] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model will be described in detail below. Example 1

[0018] like Figure 1-4 As shown, this utility model is a foldable 24-hour urine collection device, including a disposable collection mechanism 1 and a support 6, with the collection mechanism 1 supported by the support 6.

[0019] like Figure 2As shown, the collecting mechanism 1 includes an upper support 2, a bellows 3, and a lower support 4. The bellows 3 can be folded and retracted. The bellows 3 is located between the upper support 2 and the lower support 4. After the upper support 2 and the lower support 4 are connected by a snap-fit, the bellows 3 is folded and retracted between the two. At this time, the upper support 2 and the lower support 4 can protect the bellows 3 and prevent damage. In use, the upper support 2 and the lower support 4 are separated. Under the gravity of the lower support 4, the bellows 3 will be pulled downward and then automatically unfolded.

[0020] The upper support 2 has an opening on its surface, and the top cover 21 matches the opening. The top cover 21 is hinged to the surface of the upper support 2, so the top cover 21 can be opened to expose the opening, making it easy to pour urine in. A handle 23 is fixedly installed on the surface of the top cover 21 away from the hinge point, and the handle 23 is integrated with the top cover 21.

[0021] like Figure 3 As shown, a circular locking block 22 is installed on the lower surface of the upper support base 2. The locking block 22 and the upper support base 2 are an integral structure. The upper support base 2, the top cover 21 and the handle 23 of the locking block 22 are all made of hard plastic.

[0022] The hollowed-out portion in the middle of the card block 22 is located directly below the top cover 21. The upper part of the corrugated tube 3 is the connecting part 31, which is used to bond and fix it to the card block 22. The upper part of the corrugated tube 3 is open, and the outer wall of the opening is smooth and cannot be folded. The height of the connecting part is the same as the thickness of the card block 22, and the outer diameter of the connecting part matches the inner diameter of the hollowed-out portion of the card block 22. Therefore, the connecting part 31 of the corrugated tube 3 can extend into the hollowed-out portion of the card block 22, and the smooth outer wall is also more convenient to bond with the inner wall of the card block 22.

[0023] The corrugated tube 3 is an existing technology. It is made of transparent plastic and the middle part of the corrugated tube 3 is a foldable part. It should be noted that the upper wall of the corrugated tube 3 is tightly fitted with the lower wall of the upper support part 2 to prevent urine leakage. At the same time, the surface of the corrugated tube 3 is provided with scale lines, and the data can be read through the scale lines to determine the amount of urine.

[0024] The bottom of the corrugated pipe 3 is flat and is bonded to the lower support part 4. The lower support part 4 is dish-shaped. The bottom of the corrugated pipe 3 extends into the lower support part 4 and is bonded and fixed to the bottom of the lower support part. The side wall of the lower support part 4 near the inner side has a stepped groove 41 that is recessed downwards. The groove 41 matches the locking block 22. The locking block 22 can be inserted into the groove 41, thereby realizing the locking between the two, which can also be called insertion.

[0025] The bottom of the slot 41 is a certain distance from the bottom of the lower support 4. The thickness of the corrugated tube 3 after compression and folding is less than this distance, so the corrugated tube 3 can be completely retracted into the lower support 4.

[0026] After the bellows 3 is compressed and folded, the diameter of the foldable part in the middle will exceed the diameter of the opening at the top. When the bellows 3 is compressed and folded to the limit, the diameter of the foldable part of the bellows 3 reaches its maximum. However, the maximum diameter is still smaller than the maximum diameter of the locking block 22. Therefore, when the locking block 22 engages with the locking groove 41, it will not affect the bellows 3.

[0027] At the same time, the maximum diameter of the bellows 3 is smaller than the diameter of the bottom of the lower support 4, so the bellows 3 will not rub against the lower support 4, reducing the probability of damage.

[0028] In this embodiment, a drain valve 5 is installed on the lower support 4. The inlet end of the drain valve 5 extends into the bellows 3, and the outlet end of the drain valve 5 faces vertically downward. Samples can be taken for testing through the drain valve 5. The drain valve 5 is a conventional technology and a ball valve can be used.

[0029] The lower support part 4 is made of the same material as the upper support part 2. When in use, the foldable part of the bellows 3 will automatically unfold due to the gravity of the lower support part 4 and the drain valve 5. At the same time, in conjunction with the 24-hour urine volume, the bellows 3 will fully unfold, which will not affect the reading of the scale line, nor will it affect the measurement of urine volume due to not fully unfolding.

[0030] like Figure 4 As shown, the bracket 6 includes a circular clamp 61 and multiple legs 62. The legs 62 are evenly fixed on the clamp 61, and the lower ends of the legs 62 are all tilted outward at the same angle. After the legs 62 are pushed outward, the support is more stable.

[0031] In this embodiment, the diameter of the upper support 2 is greater than the maximum diameter of the card block 22. Therefore, the outer edge of the upper support 2 protrudes. Through this protruding part, it can be connected to the bracket 6 to support and fix the collecting mechanism 1.

[0032] The diameter of clamp 61 is larger than the maximum diameter of clamp block 22, while the diameter of clamp 61 is smaller than the diameter of upper support 2. Therefore, during use, the entire collection mechanism 1 can be placed into clamp 61 from top to bottom, and support can be achieved by the lower wall of upper support 2 fitting against clamp 61. Furthermore, the length of support leg 62 is sufficient, so even after the collection mechanism 1 is fully extended, the drain valve 5 is still a large distance from the plane where the lower end of support leg 62 is located, which will not affect the sampling and testing work.

[0033] The bracket 6 should be made of metal, which is strong enough and not easily worn out even after long-term use.

[0034] The following is a method of using a foldable 24-hour urine collection device according to this embodiment: First, take a brand new collection mechanism 1, manually separate the upper support 2 and the lower support 4, then hold the upper support 2 and lift the entire collection mechanism 1. Place the collection mechanism 1 into the clamp 61 from top to bottom from above the clamp 61 of the support 6. Finally, the clamp 61 will fit against the lower wall of the upper support 2, thus supporting the collection mechanism 1. After each urination, the patient opens the top cover 21 through the handle 23 and pours the excreted urine into the corrugated tube 3 until the 24-hour record is completed. The urine volume for 24 hours can be read through the scale lines on the corrugated tube 3. A portion can be taken out for testing through the drain valve 5. After all the steps are completed, drain all the urine through the drain valve 5, and then remove the collection mechanism 1 and discard it directly. Example 2

[0035] Based on Example 1, this embodiment adds a baffle, which is located in the inner cavity of the bellows 3. The specific installation method is as follows: the baffle is circular, and its diameter is smaller than the inner diameter of the connecting part 31. The baffle is inclined, and a fixing rod extends vertically from the end with a higher horizontal height. The fixing rod fits against the connecting part 31 and is connected to the locking block 22 by a screw passing through the connecting part to fix the baffle.

[0036] The baffle is tilted, with the higher end flush with the lower wall of the locking block 22 and the lower end much lower than the lower wall of the locking block 22. When urine is poured in, the urine will be guided along the baffle and then fall into the corrugated pipe 3, which can reduce urine splashing.

[0037] The corrugated pipe 3 cannot be fully folded due to the presence of the baffle. That is, the thickness of the corrugated pipe after shrinking and folding will increase. However, at this time, the distance between the bottom of the slot 41 and the bottom of the lower support 4 is still greater than the thickness, so it will not affect the corrugated pipe 3. Example 3

[0038] Based on Example 1, this embodiment can add a urinal funnel. The urinal funnel is funnel-shaped, and the bottom pipe of the urinal funnel has threads on the outer wall. The top cover 21 has a matching threaded hole at its center. The urinal funnel is threadedly connected to the top cover 21, and the bottom pipe of the urinal funnel can extend into the corrugated pipe 3. When in use, the patient can urinate directly into the urinal funnel without having to collect the urine through other containers and then pour the urine into the collection mechanism 1, which is more convenient.

[0039] Of course, in this mode, the top cover 21 does not need to be openable, and the handle 23 can be removed. Only a one-way valve needs to be installed on the bottom pipe of the urinal, so that urine can only enter and cannot flow back, thus avoiding the spread of odor.

[0040] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
