Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a disposable urine collector which can be used for 24-hour urine sampling. Background Art

[0002] Urine testing is a commonly used examination method in hospitals, which includes routine urine analysis, detection of formed components in urine, quantitative determination of protein components, urine enzyme determination, etc. Auxiliary diagnosis is performed by testing and analyzing the patient's urine.

[0003] Clinically, urine excreted by patients within 24 hours is collected, and the current condition is determined by testing the content of each component in the urine. Since the caliber of the urine sediment tube is small, patients are generally asked to urinate into a urine cup or disposable paper cup first, and then the urine in the urine cup is poured into the urine sediment tube and sent to the laboratory for testing.

[0004] However, there are currently the following problems in the process of collecting urine samples from patients:

[0005] 1. When transferring urine from the urine cup to the urine sediment tube, it is easy to pour urine on your hands, table or ground. This transfer method not only requires extra caution, consumes a lot of time and energy, and is easy to cause contamination, but also requires wiping the body, urine sediment tube or clothes, causing a series of troubles.

[0006] Second, because urine contains some trace substances, affected by the density of the substances, these substances will separate from the urine body and precipitate after a period of time. When medical staff take urine samples, in order to increase the accuracy of the experimental results, they will use a stirring rod to mix the urine body and the precipitated substances, and then conduct corresponding tests. There is a risk of urine spillage and contamination during the stirring and mixing process, and the ammonia smell produced by urine will cause certain visual and olfactory stimulation to medical staff, causing discomfort to medical staff.

[0007] Therefore, there is a need for a disposable urine collector that can conveniently transfer urine and remix urine samples. Utility Model Content

[0008] The utility model aims to provide a disposable urine collector which can be used for 24-hour urine sampling, can conveniently and safely transfer urine samples, and can effectively stir and mix before transferring.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A disposable urine collector that can be used for 24-hour urine sampling comprises a cup body and a urine sediment tube, wherein the cup body is provided with a collecting port, and the collecting port is detachably connected with a sealing cover, the side wall of the cup body is provided with a liquid outlet pipe that bends downward and extends, and the liquid outlet pipe is connected to the inside of the cup body, the end of the liquid outlet pipe facing the bottom of the cup is a liquid outlet, and the urine sediment tube is detachably connected to the liquid outlet.

[0011] Compared with the prior art, the disposable urine collector for 24h urine sampling using the above technical solution has the following beneficial effects:

[0012] 1. The disposable urine collector of the utility model can be used for 24h urine sampling. After the urine is discharged into the cup body through the collection port, the sealing cover is covered to isolate the urine from the outside world, and the urine can be transferred from the cup body to the urine sediment tube by tilting the cup body through the guiding structure of the liquid outlet pipe. During the transfer process, the urine will not contact the outside world, effectively avoiding a series of problems caused by transferring urine.

[0013] Second, due to the special structure of the liquid outlet tube, the part of the tube body where the liquid outlet is located is vertically downward. After the cup body is tilted, the cup body can be reset, and part of the urine will continue to flow from the liquid outlet tube into the urine sediment tube. There is no need to maintain the tilted state for a long time, and the operation is labor-saving and convenient; and the amount of urine flowing into the urine sediment tube can be effectively controlled to avoid the urine sediment tube being directly filled, thereby facilitating subsequent experiments.

[0014] Preferably, the mouth of the urine sediment tube is threadedly connected to the cover body, the outer wall of the mouth of the urine sediment tube is provided with an external thread, the inner wall of the liquid outlet is provided with an internal thread groove, a liquid guide tube is provided in the liquid outlet tube, and the outer wall of the end of the liquid guide tube close to the inside of the cup body is connected to the inner wall of the liquid outlet tube through a guide ring, and when the urine sediment tube is docked with the liquid outlet, the outer wall of the liquid guide tube fits with the inner wall of the urine sediment tube. Since the urine sediment tube can be docked with the cover body and the liquid outlet respectively through a threaded connection structure, the connection state is stable, and the structures connected at the two places are universally adaptable, easy to use, and save the processing cost caused by adding a docking structure; and through the connection and guiding effect of the guide ring, the urine turns to flow into the liquid guide tube at the moment of entering the liquid outlet tube, and directly flows into the urine sediment tube, which can effectively prevent part of the urine from flowing into the docking gap between the urine sediment tube and the liquid outlet, thereby avoiding the pollution problem caused by urine leakage.

[0015] Preferably, the side wall of the cup body is provided with a fixing groove of an arc structure, and the inner wall of the fixing groove is provided with a constraint layer made of elastic material, the width of the constraint layer corresponding to the notch of the fixing groove does not exceed the inner diameter of the fixing groove, and the urine sediment tube and the cover body can be clamped in the fixing groove. By utilizing the elastic properties of the elastic material and the special width of the notch of the constraint layer, the urine sediment tube and the fixing groove can be temporarily docked, so that the urine sediment tube and the cup body are in an integrated structure, which is convenient for transfer and can reduce the occupied space, meeting the storage needs of the hospital.

[0016] Preferably, a groove for inserting a finger is provided on one side of the fixing groove close to the sealing cover, and the groove is connected to the fixing groove. The finger can contact the cover of the urine sediment tube through the groove, thereby facilitating the hand to apply force to pry the urine sediment tube, so as to quickly remove the urine sediment tube from the fixing groove, and the access structure does not affect the storage and fixing state of the urine sediment tube under normal conditions.

[0017] Preferably, a plurality of spoilers are provided at the bottom of the cup body, and the plurality of spoilers are arranged in an interlaced manner. Before transferring the urine to the urine sediment tube, by shaking the cup body and the interlaced spoiler structure, the urine in the cup body can be properly stirred and mixed with the sediment to meet the stirring requirements of the urine sample during the test.

[0018] Preferably, the cup body is rotatably connected with an inner shell, the spoiler is connected to the bottom of the cup body through a support rod, and the support rod is arranged through the bottom of the inner shell, the sealing cover can be fixed with the inner shell, and the sealing cover is rotated to drive the inner shell to rotate synchronously, the inner shell is provided with an opening adapted to the liquid outlet pipe, and the sealing cover is provided with an identification strip for guiding the opening to dock with the liquid outlet pipe. Since the sealing cover and the inner shell can be temporarily integrated by a snap-fitting manner, when the sealing cover rotates through the inner shell, the urine in the inner shell can be driven to rotate autonomously because the support rod and the inner shell are relatively independent, thereby realizing the relative movement of urine and the spoiler, so as to further increase the stirring and mixing effect, and no electric control structure is required, thereby reducing the use cost and medical cost; and after the stirring is completed, the identification strip and the position of the liquid outlet pipe can be coordinated to facilitate quick identification and adjustment of the sealing cover to the position required for discharge.

[0019] Preferably, the sealing cover is provided with an adjustment slot for easy insertion of a hand, and a lifting rod is provided in the adjustment slot. Through the lifting rod structure built into the sealing cover, the rotation state of the sealing cover can be effectively controlled, and the sealing cover can be opened and closed conveniently.

[0020] Preferably, the cup body, the liquid outlet tube and the liquid guide tube are all made of transparent materials. By utilizing the light-transmitting property of the transparent materials, the urine inside can be directly observed through the cup body, the liquid outlet tube and the liquid guide tube, so as to further stir when the mixing is incomplete or transfer the urine in time when the urine stock is large.

DETAILED DESCRIPTION

[0030] The utility model is further described below in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figures 1 to 7 The disposable urine collector shown can be used for 24-hour urine sampling, and comprises a cup body 1 and a urine sediment tube 2 .

[0033] A handle is provided on one side of the cup body 1 , a collecting port 10 is provided above the cup body 1 , and the collecting port 10 is detachably connected to a sealing cover 3 .

[0034] The side wall of the cup body 1 is provided with a liquid outlet pipe 4 that bends downward and extends, and the liquid outlet pipe 4 is connected to the inside of the cup body 1, and the end of the liquid outlet pipe 4 facing the bottom of the cup is a liquid outlet 40, and the pipe mouth of the urine sediment tube 2 is threadedly connected to the cover body 20, and the urine sediment tube 2 and the liquid outlet 40 are detachably connected.

[0035] Regarding the connection structure between the urine sediment tube 2 and the liquid outlet 40, it can be directly inserted for clamping, or the liquid outlet 40 can be provided with a corresponding clamping structure, or it can be a threaded connection. In this embodiment, the urine sediment tube 2 and the self-contained cover body 20 are considered to be a threaded connection structure. In order to save processing costs and the versatility and connection stability of the connection structure, the urine sediment tube 2 and the liquid outlet 40 also adopt a threaded connection structure, that is, the outer wall of the tube mouth of the urine sediment tube 2 is provided with an external thread, and the inner wall of the liquid outlet 40 is provided with an internal thread groove.

[0036] In order to prevent part of the urine from flowing into the threaded connection (the gap between the urine sediment tube 2 and the liquid outlet 40), in this embodiment, a liquid guide tube 5 is provided in the liquid outlet tube 4, and the outer wall of the liquid guide tube 5 at one end close to the inside of the cup body 1 is connected to the inner wall of the liquid outlet tube 4 through a guide ring 50. When the urine sediment tube 2 is connected to the liquid outlet 40, the outer wall of the liquid guide tube 5 fits with the inner wall of the urine sediment tube 2, that is, the liquid outlet tube 4 has a connecting function, and the liquid guide tube 5 has a function of guiding urine.

[0037] In order to facilitate the unified carrying or transfer of various components in the disposable urine collector, the side wall of the cup body 1 is provided with an arc-shaped fixing groove 6, and the inner wall of the fixing groove 6 is provided with a constraint layer 60 made of elastic silicone or elastic rubber. The width of the constraint layer 60 corresponding to the notch of the fixing groove 6 does not exceed the inner diameter of the fixing groove 6, and the urine sediment tube 2 and the cover body 20 can both be clamped in the fixing groove 6.

[0038] When the above-mentioned unified carrying requirement is met, in order to facilitate quick removal of the urine sediment tube 2 , a groove 7 for finger insertion is provided on one side of the fixing groove 6 close to the sealing cover 3 , and the groove 7 is communicated with the fixing groove 6 .

[0039] In order to meet the experimental requirements of stirring urine, a plurality of spoilers 8 are provided at the bottom of the cup body 1, and the plurality of spoilers 8 are arranged in an interlaced manner.

[0040] In this embodiment, in order to increase the stirring effect, the inner shell 11 is rotatably connected to the cup body 1, the spoiler 8 is connected to the bottom of the cup body 1 through the support rod 80, and the support rod 80 is arranged to penetrate the bottom of the inner shell 11, and the sealing cover 3 can be clamped and fixed with the inner shell 11, and the sealing cover 3 is rotated to drive the inner shell 11 to rotate synchronously. Figure 2 and Figure 4 As shown, a clamping block is provided on the inner side of the sealing cover 3 , and a corresponding clamping groove is provided on the inner shell 11 .

[0041] The inner shell 11 is provided with an opening 12 adapted to the liquid outlet pipe 4, and the sealing cover 3 is provided with an identification strip 30 for guiding the opening 12 to dock with the liquid outlet pipe 4, that is, the urine can be transferred after stirring.

[0042] In addition, in order to facilitate the control of the active state of the sealing cover 3, the sealing cover 3 is provided with an adjustment slot 31 for easy insertion of the hand, and a lifting rod 32 is provided in the adjustment slot 31. In addition, in order to facilitate the checking of the amount of urine stored and the observation of the urine being transferred, the cup body 1, the inner shell 11, the liquid outlet pipe 4 and the liquid guide pipe 5 are all made of transparent materials (such as transparent PVC or transparent PE).

[0043] The following is the usage of this embodiment:

[0044] First, the patient can separate the sealing cover 3 from the cup body 1 by holding the lifting rod 32, so that the inner shell 11 is exposed to the outside, and after the urine is placed into the inner shell 11 from the collection port 10, the sealing cover 3 is put back on. Then, the patient inserts a finger into the groove 7, and the finger can touch the cover 20 of the urine sediment tube 2, and the cover 20 is moved, and the constraint layer 60 in the fixed groove 6 is contracted by force, so that the urine sediment tube 2 and the cover 20 are separated from the fixed groove 6.

[0045] Afterwards, the cover 20 on the urine sediment tube 2 is unscrewed, and the urine sediment tube 2 and the liquid outlet 40 are threadedly connected. At this time, part of the liquid guide tube 5 is inserted into the urine sediment tube 2, and the outer wall of the liquid guide tube 5 fits with the inner wall of the urine sediment tube 2.

[0046] During the first step, if the patient has a large urine output or for safety reasons, the urine sediment tube 2 may be connected to the liquid outlet 40 first.

[0047] Next, the orientation of the sealing cover 3 is adjusted so that the sealing cover 3 and the inner shell 11 are snap-fitted and fixed, and the sealing cover 3 is rotated back and forth by holding the lifting rod 32. Since the support rod 80 of the spoiler 8 and the inner shell 11 are relatively independent, during the rotation of the inner shell 11, the spoiler 8 and the urine in the inner shell 11 produce relative movement, thereby achieving stirring of the urine.

[0048] After stirring for several times, the sealing cover 3 is rotated so that the marking strip 30 is aligned with the position of the liquid outlet pipe 4, that is, the opening 12 of the inner shell 11 is aligned with the liquid outlet pipe 4. Then, the handle of the cup body 1 is held and the cup body 1 is tilted so that the stirred urine in the inner shell 11 flows toward the opening 12. After passing through the opening 12, the urine directly passes through the liquid guide tube 5 and enters the urine sediment tube 2 to collect the urine.

[0049] Embodiment 2:

[0050] like Figure 8As shown, the technical contents of this embodiment are basically the same as those of Embodiment 1, and the technical differences between this embodiment and Embodiment 1 are:

[0051] In this embodiment, the cup body 1 is not provided with a spoiler 8, and a plurality of spoilers 8 are connected to the inner side of the sealing cover 3 through a connecting rod 81, and the plurality of spoilers 8 are arranged alternately. In order to facilitate the purpose of stirring and sealing the collection port 10, the outer structure of the sealing cover 3 is the same as that of the embodiment 1, that is, the sealing cover 3 is provided with an adjustment slot 31 for convenient hand insertion, and a lifting rod 32 is provided in the adjustment slot 31.

[0052] The following is the usage of this embodiment:

[0053] Referring to the method of Example 1, after the urine is discharged into the cup body 1, the lifting rod 32 on the outside of the sealing cover 3 is held to insert the connecting rod 81 and the spoiler 8 into the cup body 1 to seal the collection port 10, and the urine can be stirred by shaking the cup body 1 or rotating the sealing cover 3.

[0054] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be regarded as within the protection scope of the present invention.
