Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a telescopic urine collection tube. Background Art

[0002] The urine collectors currently used on the market are all in the form of traditional urine cups. Although they are inexpensive and quick and easy to use, users will inevitably come into contact with urine when using the urine cup for urine sampling, and will inevitably be contaminated by urine. In addition, a fixed place is required for urine collection, and the use environment is limited. After the collection is completed, the user needs to be careful and slow during the urine sample delivery process, otherwise the urine is likely to spill or slip, causing the user to be contaminated by urine multiple times and the environment to be polluted. In addition, during the sample delivery process, the surrounding environment is very likely to contaminate the urine sample. If the sample falls during the delivery process, it will directly cause the urine collection to fail, causing great inconvenience to the user.

[0003] To solve the above problems, an existing patent (publication number: CN213963462U) discloses a urine collector that is convenient for urine collection. However, after collecting urine, the first pull rod and the second pull rod are both stored in the collection tube, which occupies the storage space of the collection tube and reduces the collection volume of the urine sample. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A telescopic urine collection tube comprises a collection tube, a tube cover detachably mounted on the top of the collection tube, a funnel detachably mounted on the top of the tube cover, a collection cup housed inside the funnel, a flow guide opening being provided at the bottom of the collection cup, a lifting rod being slidably connected to the collection cup, a cone head being provided at the bottom end of the lifting rod, a first rotating plate being fixedly connected to the top end of the lifting rod, a second rotating plate being rotatably connected to the side wall of the first rotating plate, an extension rod being fixedly connected to the top end of the second rotating plate, a storage cylinder being sleeved on the outer surface of the extension rod, and a sealing cap being detachably mounted on the top end of the storage cylinder;

[0007] A rotating shaft is installed on the side wall of the second rotating plate, a circular hole adapted for the rotating shaft is opened on the side wall of the first rotating plate, and a limiting rod is fixedly connected to the second rotating plate, which acts on the first rotating plate to keep the first rotating plate and the second rotating plate in a vertical state when in use.

[0008] Based on the above technical solution, its use principle and the technical effects produced are as follows:

[0009] When urine needs to be collected, first open the cover, take out the extension rod, storage tube, lifting rod and collection cup, then deflect the first rotating plate around the rotating axis on the second rotating plate and limit it with the limit rod, then use the storage tube and the cover as a gripping part, hold the gripping part when in use, then pull the extension rod out of the storage tube, extend the distance between the gripping part and the collection cup, and avoid splashing the urine sample on the hand during collection, then the collection cup will naturally slide to the bottom of the lifting rod, and make the guide port clamped on the cone head, at this time the cone head and the guide port fit tightly, and then the urine can be collected. After the collection is completed, due to the weight of the collection cup becoming heavier, the guide port on the collection cup is now more tightly clamped with the cone head, which can prevent the urine in the collection cup from leaking from the guide port. , and then place the collection cup in the funnel. At this time, the lifting rod will slide downward under the action of gravity, so that the guide port is separated from the cone head, and because the diameter of the guide port is larger than the diameter of the lifting rod, the urine sample will flow downward along the gap between the lifting rod and the guide port into the collection tube. As the lifting rod continues to slide down, the limit columns on both sides of it will be stuck at the upper end of the guide port, and the extension rod will be stored in the storage cylinder, so that the entire storage area of ​​the lifting rod, extension rod and storage cylinder is located above the collection tube, which is convenient for reducing the space volume inside the collection tube occupied by it and increasing the storage volume for the urine sample. After the urine collected in the collection cup enters the collection tube, the funnel is removed and the cover is buckled on the top of the tube cover to achieve sealing of the upper part of the collection tube, which is convenient for urine testing.

[0010] In a preferred example, the present invention can be further configured as follows: the collection tube and the tube cover are connected by a thread or a clamp, and the tube cover and the funnel are connected by a thread or a clamp.

[0011] In a preferred example, the present invention can be further configured as follows: the cross-sectional shape of the collection cup and the funnel is set to be circular or square.

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other in the absence of conflict.

[0033] According to the concept of this application, Figures 1 to 5 An embodiment of a telescopic urine collection tube 1 for collecting urine test samples will now be described. Specifically, the telescopic urine collection tube 1 is constructed as a split structure, comprising three components: a collection tube 1, a collection cup 4, and a lifting rod 6. The interplay between a storage tube 11, a first rotating plate 8, an extension rod 10, and the lifting rod 6 allows the extension rod 10 to be stored within the storage rod, positioning the entire storage area of ​​the lifting rod 6, extension rod 10, and storage tube 11 above the collection tube 1. This reduces the volume of space occupied by the extension rod 10 within the collection tube 1 and facilitates increased storage capacity for urine samples. Furthermore, the interplay between the first rotating plate 8, the second rotating plate 9, and the rotating shaft 13 facilitates bending between the lifting rod 6 and the extension rod 10 during urine sample collection, making it easier to grip and preventing urine from splashing onto hands. Furthermore, a stopper 15 limits the deflection position of the first rotating plate 8 to prevent excessive deflection.

[0034] Combine Figure 1-Figure 5 As shown, the utility model provides a telescopic urine collection tube 1, comprising a collection tube 1, a tube cover 2 detachably mounted on the top of the collection tube 1, a funnel 3 detachably mounted on the top of the tube cover 2, a collection cup 4 housed inside the funnel 3, a guide port 5 being provided at the bottom of the collection cup 4, a lifting rod 6 being slidably connected to the collection cup 4, a cone head 7 being provided at the bottom end of the lifting rod 6, a first rotating plate 8 being fixedly connected to the top of the lifting rod 6, a second rotating plate 9 being rotatably connected to the side wall of the first rotating plate 8, an extension rod 10 being fixedly connected to the top of the second rotating plate 9, a storage tube 11 being sleeved on the outer surface of the extension rod 10, and a sealing cap 12 being detachably mounted on the top of the storage tube 11;

[0035] A rotating shaft 13 is installed on the side wall of the second rotating plate 9, and a circular hole 14 adapted to the rotating shaft 13 is opened on the side wall of the first rotating plate 8. A limiting rod 15 is fixedly connected to the second rotating plate 9, and the limiting rod 15 acts on the first rotating plate 8 to keep the first rotating plate 8 and the second rotating plate 9 in a vertical state when in use.

[0036] The collection tube 1 is mainly used to store the collected urine samples. According to the technical solution of the present application, the collection tube 1 and the tube cover 2 can be detachably connected by means of threaded connection or clip connection. This embodiment is not limited here and can be selected according to actual conditions. It should be noted that a cover plate is fixedly connected to the side wall of the tube cover 2 through a thin wall, and the cover plate and the top opening of the tube cover 2 are adapted to each other, so that after the sample is collected, the tube cover 2 can be closed with the cover plate to prevent the sample from spilling.

[0037] According to the technical solution of the present application, the tube cover 2 and the funnel 3 can be detachably connected by means of threaded connection or snap connection. This embodiment is not limited here and can be selected according to actual conditions. A cavity for accommodating the collection cup 4 is provided inside the funnel 3, and the top of the funnel 3 and the sealing cover 12 are also detachably connected by means of threaded connection or snap connection. When sampling is required, the sealing cover 12 is opened and the collection cup 4 is taken out of the funnel 3.

[0038] With respect to the technical solution of the present application, the cross-sectional shape of the collection cup 4 and the funnel 3 can be set to a circular, square or other polygonal shape. This embodiment does not make any specific restrictions here and can be selected according to actual conditions. It should be noted that, based on this embodiment, only the shapes of the collection cup 4, funnel 3 and other structures are changed, which still falls within the protection scope of this embodiment.

[0039] According to the technical solution of this embodiment, the diameter of the cone head 7 gradually decreases from the bottom to the top, and the inner wall of the guide port 5 is set to a conical surface shape that matches the cone head 7. The diameter of the upper end of the guide port 5 is larger than the diameter of the lifting rod 6. When urine is collected, the collection cup 4 will move downward under the action of gravity, so that the guide port 5 falls into the cone head 7. At this time, the cone head 7 will fit tightly with the guide port 5 to achieve sealing, and the urine sample can be collected.

[0040] The lifting rod 6 and the extension rod 10 are coaxially arranged, and the top of the extension rod 10 is fixedly connected with a baffle 16. The diameter of the baffle 16 is larger than that of the extension rod 10, and the diameter of the baffle 16 is equal to the inner diameter of the storage tube 11. The baffle 16 can be used to limit the extension rod 10 to prevent it from being separated from the storage tube 11. When collecting samples, the extension rod 10 and the storage tube 11 can be used to store the extension rod 10 in the storage tube 11 when the collection cup 4 is placed in the funnel 3, so that the entire storage area of ​​the lifting rod 6, the extension rod 10 and the storage tube 11 is located above the collection tube 1, reducing the space volume occupied by the lifting rod 6, the extension rod 10 and the storage tube 11, thereby increasing the storage volume of the urine sample. In addition, when collecting urine, the storage tube 11 can also serve as a grip. By pulling out the extension rod 10, the length of the grip can be extended, which is convenient for the user to hold the collection cup 4 during sampling, and effectively prevents urine from splashing on the hands during collection.

[0041] According to the technical solution of this embodiment, the top end of the storage tube 11 is set to be open, the outer surface of the storage tube 11 is provided with a thread, and is detachably connected to the cover 12 through the thread, and the bottom end of the storage tube 11 is provided with a through hole that is compatible with the extension rod 10, and the diameter of the through hole is smaller than the diameter of the baffle 16. After the storage tube 11 is removed from the cover 12, the extension rod 10 can be taken out of the storage tube 11 through the opening provided at the top end of the storage tube 11, so that when the extension rod 10 is accidentally broken, it can be partially replaced to avoid the entire device from being scrapped.

[0042] According to the technical solution of this embodiment, a convex ring is provided on the outer side of one end of the rotating shaft 13 away from the second rotating plate 9. The diameter of the convex ring is larger than the diameter of the rotating shaft 13, and the convex ring extends smoothly to the outer surface of the rotating shaft 13. The diameter of the circular hole 14 on the first rotating plate 8 is smaller than the diameter of the convex ring and larger than the diameter of the rotating shaft 13. The entire device is made of plastic material, and the plastic has a certain elasticity. Therefore, the first rotating plate 8 can be clamped on the rotating shaft 13 through the circular hole 14 and limited by the convex ring. In this way, the deflection movement between the first rotating plate 8 and the second rotating plate 9 can be achieved, so that when collecting urine samples, the lifting rod 6 and the extension rod 10 are bent, which is not only convenient for holding, but also can prevent urine from splashing on the hands.

[0043] Furthermore, the number of the limiting rods 15 is set to two. When the first rotating plate 8 deflects on the second rotating plate 9, the limiting rods 15 can be used to limit the first rotating plate 8 so that the first rotating plate 8 and the second rotating plate 9 remain in a vertical state, that is, when the extension rod 10 remains horizontal, the lifting rod 6 and the collection cup 4 are both in a vertical state.

[0044] According to the technical solution of this embodiment, a limiting column 17 is fixedly connected to the top side wall of the lifting rod 6. The limiting column 17 is hemispherical in shape. There are two limiting columns 17. The two limiting columns 17 are arranged in a mirror-symmetrical manner with the central axis of the lifting rod 6 as the axis of symmetry, and the distance between the farthest points of the two limiting columns 17 is greater than the inner diameter of the top of the guide port 5. When the collection cup 4 is placed in the funnel 3, the lifting rod 6 will move downward under the action of gravity. At this time, the limiting columns 17 on both sides are stuck in the upper end of the guide port 5, which can limit the lifting rod 6 to prevent it from moving further downward. At the same time, it is also convenient for the extension rod 10 and the storage tube 11 to achieve the contraction operation, which is convenient for storage.

[0045] Specifically, when urine needs to be collected, first open the cover 12, take out the extension rod 10, the storage tube 11, the lifting rod 6 and the collection cup 4, then deflect the first rotating plate 8 on the second rotating plate 9 around the rotating shaft 13 and limit it with the limiting rod 15, then use the storage tube 11 and the cover 12 as a gripping part, hold the gripping part when in use, then pull the extension rod 10 out of the storage tube 11, extend the distance between the gripping part and the collection cup 4, and avoid the urine sample splashing on the hand during collection, then the collection cup 4 will naturally slide to the bottom of the lifting rod 6, and make the guide port 5 clamped on the cone head 7, at this time the cone head 7 is tightly fitted with the guide port 5, and then the urine can be collected. After the collection is completed, due to the weight of the collection cup 4 becoming heavier, the guide port 5 on the collection cup 4 is more tightly clamped with the cone head 7, which can prevent the urine in the collection cup 4 from leaking out of the guide port After the urine collected in the collection cup 4 enters the collection tube 1, the funnel 3 is removed and the cover is buckled on the top of the tube cover 2 to achieve the closure of the upper part of the collection tube 1, which is convenient for urine testing.

[0046] The telescopic urine collection tube 1 provided by the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] A telescopic urine collection tube 1 comprises a collection tube 1, a tube cover 2 being detachably mounted on the top of the collection tube 1, a funnel 3 being detachably mounted on the top of the tube cover 2, a collection cup 4 being accommodated within the funnel 3, a flow guide port 5 being provided at the bottom of the collection cup 4, a lifting rod 6 being slidably connected to the collection cup 4, a cone head 7 being provided at the bottom end of the lifting rod 6, a first rotating plate 8 being fixedly connected to the top end of the lifting rod 6, a second rotating plate 9 being rotatably mounted on the side wall of the first rotating plate 8, an extension rod 10 being fixedly mounted to the top end of the second rotating plate 9, a storage tube 11 being sleeved on the outer surface of the extension rod 10, and a sealing cap 12 being detachably mounted on the top end of the storage tube 11;

[0048] A rotating shaft 13 is installed on the side wall of the second rotating plate 9, and a circular hole 14 adapted to the rotating shaft 13 is opened on the side wall of the first rotating plate 8. A limiting rod 15 is fixedly connected to the second rotating plate 9, and the limiting rod 15 acts on the first rotating plate 8 to keep the first rotating plate 8 and the second rotating plate 9 in a vertical state when in use.

[0049] The working principle and usage process of the present invention are as follows: when urine needs to be collected, the cover 12 is first opened, the extension rod 10, the storage tube 11, the lifting rod 6 and the collection cup 4 are taken out, and then the first rotating plate 8 is deflected on the second rotating plate 9 around the rotating shaft 13 and is limited by the limiting rod 15, and then the storage tube 11 and the cover 12 are used as a gripping part. When in use, the gripping part is held by hand, and the extension rod 10 is pulled out of the storage tube 11 to extend the distance between the gripping part and the collection cup 4 to prevent the urine sample from splashing on the hand during collection. Then the collection cup 4 will naturally slide to the bottom of the lifting rod 6 and make the guide port 5 clamped on the cone head 7. At this time, the cone head 7 is tightly fitted with the guide port 5, and then the urine can be collected. After the collection is completed, due to the weight of the collection cup 4 becoming heavier, the guide port 5 on the collection cup 4 is more tightly clamped with the cone head 7, which can prevent the urine in the collection cup 4 from splashing. After the urine leaks out from the guide port 5, the collection cup 4 is placed in the funnel 3. At this time, the lifting rod 6 will slide downward under the action of gravity, so that the guide port 5 is separated from the cone head 7. Since the diameter of the guide port 5 is larger than the diameter of the lifting rod 6, the urine sample will flow downward along the gap between the lifting rod 6 and the guide port 5 into the collection tube 1. As the lifting rod 6 continues to slide down, the limit columns 17 on both sides thereof will be stuck at the upper end of the guide port 5, and the extension rod 10 will be stored in the storage cylinder 11, so that the entire storage area of ​​the lifting rod 6, the extension rod 10 and the storage cylinder 11 are all located above the collection tube 1, which is convenient for reducing the space volume inside the collection tube 1 occupied by it and for increasing the storage volume for the urine sample. After the urine collected in the collection cup 4 enters the collection tube 1, the funnel 3 is removed and the cover is buckled on the top of the tube cover 2 to achieve the closure of the upper part of the collection tube 1, which is convenient for urine testing.
