Description

Technical Field

[0001] The utility model relates to the technical field of urine collecting devices, in particular to a pollution-proof disposable mid-section urine collecting and storing device. Background Art

[0002] In clinical urology and laboratory departments, it is necessary to intercept the middle section of urine as a sample for urine examination for medical testing. The main purpose is to eliminate the contamination and influence of urethral inflammation on urine components. Previously, patients or family members were required to use urine cups to manually collect mid-stream urine during urination. Due to the lack of professionalism, it was difficult to ensure that the urine collected by the patient was mid-stream urine. On the other hand, it was easy to splash urine, and it was also easy for the patient to be disturbed and urinate intermittently, resulting in the possibility of re-contamination of urethral inflammation. In addition, some patients with chronic kidney disease need to return to the hospital for regular reexamination. On the day of the reexamination, they are required to collect morning urine at home and take it to the hospital for testing. However, after the urine is stored at room temperature for two hours, the stability of the effective ingredients cannot be guaranteed due to the reproduction of pathogenic microorganisms and other reasons.

[0003] When in use, most of the existing disposable mid-stream urine collection devices use an upper and lower layered plus buoyancy ball design. After the initial urine flows into the lower layer, it floats up with the help of a buoyancy ball made of lightweight material, blocking the liquid inlet of the lower layer, and then the mid-stream urine of the upper layer is collected. The buoyancy ball itself is a sphere, and it is inevitable to roll and float under the impact of the urine flow, thereby causing the urine in the lower layer to flow back upward, and it is difficult to avoid the mixing and contamination of the urine in the upper and lower layers.

[0004] For example, a mid-stream urine collector disclosed in announcement number CN215017992U, when in use, the urine collector of this patent can carry the front-stream urine discharged by the patient through the establishment of a urine collecting bottle, and a floating ball is placed inside the leakage tube, so that when urine flows into the urine collecting bottle, the urine will continue to be poured into the urine collecting bottle, thereby driving the floating ball to rise, so that when the floating ball rises to a certain level, it will block the bottom of the urine inlet of the urine collecting bottle, and the urine inlet of the urine collecting bottle is blocked by the floating floating ball, which can prevent subsequent urine from being poured into the interior, so that the front-stream urine carried by the urine collecting bottle is not easily mixed with the mid-stream urine discharged subsequently by the patient.

[0005] Since the float is a sphere, when urine flows into the urine collection bottle, the float is likely to float up and down under the impact of the urine flow. This floating may cause the float to be unable to completely and effectively block the urine inlet of the urine collection bottle. When the buoyancy ball floats up and down, it may cause the urine around it to move, which may cause the lower layer of urine to flow back upward and mix with the middle layer of urine, thereby causing the urine sample to be contaminated and affecting the accuracy of subsequent urine testing.

[0006] Therefore, it is necessary to invent a contamination-proof disposable mid-stream urine collection and storage device to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a disposable mid-section urine collection and storage device which is pollution-proof so as to solve the problems in the above-mentioned technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a contamination-proof disposable mid-section urine collection storage device, comprising a urine collection cup, a urine separator, a one-way valve assembly and a sample preservation test tube, wherein the urine separator is snap-fitted inside the urine collection cup, and the urine separator divides the inside of the urine collection cup into an upper urine storage cavity and a lower urine storage cavity, and an opening No. 1 is provided on the surface of the urine separator, and the one-way valve assembly is arranged below the urine separator, and the one-way valve assembly is composed of a latex isolation plate and a waterproof foam, and the waterproof foam is fixedly connected to the bottom of the latex isolation plate, and one end of the latex isolation plate is hinged to the bottom of the urine separator, and the other end of the latex isolation plate protrudes upward and is snap-fitted with the opening No. 1.

[0009] The urine collection cup is divided into two chambers by the urine separator plate, which can isolate the first-pass urine and the middle-pass urine; the one-way valve assembly is used to seal the No. 1 opening, which can effectively prevent the backflow of the first-pass urine and ensure the purity of the middle-pass urine.

[0010] Preferably, an exhaust pipe is fixedly connected inside the urine collection cup, a through hole is opened on the surface of the urine separator, and the top end of the exhaust pipe passes through the through hole and extends to above the urine separator.

[0011] The provision of the exhaust pipe helps to discharge the gas inside the sample preservation tube when urine flows into the sample preservation tube.

[0012] Preferably, a urinary catheter is fixedly connected inside the urine collection cup, and the urinary catheter is fixedly connected to one side of the exhaust pipe.

[0013] The setting of the catheter provides a smooth inflow channel for mid-stream urine, ensuring that urine can flow smoothly into the sample storage tube and avoiding urine splashing.

[0014] Preferably, a second opening is provided on the surface of the urine separator, and the second opening is communicated with the top end of the urinary catheter.

[0015] By designing the No. 2 opening and connecting it with the catheter, it is ensured that when the midstream urine reaches a certain height, it can smoothly flow through the catheter into the sample preservation tube, thereby realizing automatic collection of urine.

[0016] Preferably, a fixed sleeve is fixedly connected to the bottom of the urine collection cup, and the top of the sample preservation tube is inserted into the fixed sleeve.

[0017] The fixed sleeve provides a stable support and fixing structure for the sample preservation tube.

[0018] Preferably, the bottom ends of the exhaust pipe and the urinary catheter both extend into the interior of the sample preservation tube, and the interior of the sample preservation tube is pre-filled with a preservation solution.

[0019] The pre-filled preservation solution can be immediately mixed with urine, effectively inhibiting the growth of microorganisms, extending the storage time of urine samples, and ensuring the stability and reliability of samples during the inspection process.

[0020] Preferably, a rubber sealing ring is fixedly connected to the inner wall of the fixed sleeve, and the rubber sealing ring is interference-connected with the outer wall of the top end of the fixed sleeve.

[0021] The rubber sealing ring can ensure the tight connection between the sample preservation tube and the fixed sleeve, effectively preventing urine from leaking from the interface during collection and transportation, and maintaining the sealing of the entire collection and storage system.

[0022] Preferably, a handle is fixedly connected to one side of the top of the urine collection cup, an overflow port is provided at the top edge of the urine collection cup, and a pickup end block is fixedly connected to the surface of the urine separator.

[0023] The handle provides convenience for users to operate, allowing users to easily hold and operate the urine collection cup; the overflow port design can discharge excess urine in time to keep the collection process clean and hygienic; the design of the picking end block makes it easy for users to disassemble and assemble the urine separator.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. Use a one-way valve assembly to separate the first-pass urine from the middle-pass urine to prevent the first-pass urine from reflux and contaminating the middle-pass urine. When the urine enters the lower urine storage cavity, the waterproof foam floats up due to the buoyancy and the impact of urine reflux, pushing the protrusion at one end of the latex isolation plate to move upward and seal the No. 1 opening, which not only prevents urine from continuing to enter the lower urine storage cavity, but also prevents the first-pass urine from reflux and contaminating the middle-pass urine in the upper urine storage cavity, ensuring the purity of the middle-pass urine and improving the collection quality of urine samples;

[0026] 2. The sample preservation test tube is connected to the bottom of the urine collection cup through a fixed sleeve and is tightly fixed with a rubber sealing ring, which not only ensures the stability of the connection but also facilitates the disassembly and installation of the test tube. Before collecting urine, the test tube has been pre-filled with preservation solution, so that the mid-stream urine can be immediately mixed with the preservation solution after flowing into the test tube, effectively inhibiting the growth and metabolic activities of microorganisms and prolonging the preservation time of urine samples.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The utility model provides Figure 1-5 The shown embodiment is a contamination-proof disposable mid-section urine collection storage device, comprising a urine collection cup 1, a urine separator 2, a one-way valve assembly 3 and a sample preservation test tube 4. The urine separator 2 is snap-fitted inside the urine collection cup 1, and the urine separator 2 divides the inside of the urine collection cup 1 into an upper urine storage cavity 5 and a lower urine storage cavity 6. An opening No. 1 is provided on the surface of the urine separator 2. The one-way valve assembly 3 is arranged below the urine separator 2. The one-way valve assembly 3 is composed of a latex isolation plate 7 and a waterproof foam 8. The waterproof foam 8 is fixedly connected to the bottom of the latex isolation plate 7. One end of the latex isolation plate 7 is hinged to the bottom of the urine separator 2, and the other end of the latex isolation plate 7 protrudes upward and is snap-fitted to the opening No. 1.

[0036] In one aspect of the present embodiment, an exhaust pipe 9 is fixedly connected to the inside of the urine collection cup 1, a through hole is provided on the surface of the urine partition plate 2, the top of the exhaust pipe 9 passes through the through hole and extends to the top of the urine partition plate 2, a urinary catheter 10 is fixedly connected to the inside of the urine collection cup 1, the urinary catheter 10 is fixedly connected to one side of the exhaust pipe 9, a second opening 11 is provided on the surface of the urine partition plate 2, the second opening 11 is connected to the top of the urinary catheter 10, a fixed sleeve 12 is fixedly connected to the bottom of the urine collection cup 1, and the sample storage test tube 12 is fixedly connected to the bottom of the urine collection cup 1. The top end of the tube 4 is inserted into the fixed sleeve 12, the bottom ends of the exhaust pipe 9 and the catheter 10 extend into the sample preservation tube 4, the sample preservation tube 4 is pre-filled with a preservation solution 13, a rubber sealing ring 14 is fixedly connected to the inner wall of the fixed sleeve 12, the rubber sealing ring 14 is interference fit with the outer wall of the top end of the fixed sleeve 12, a handle 15 is fixedly connected to one side of the top of the urine collection cup 1, an overflow port 16 is provided at the top edge of the urine collection cup 1, and a picking end block 17 is fixedly connected to the surface of the urine separator 2.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5 When using the utility model, firstly, a certain amount of preservation liquid 13 is injected into the sample preservation tube 4, and then the top of the sample preservation tube 4 is inserted into the fixed sleeve 12, and the sample preservation tube 4 is firmly fixed by means of the rubber sealing ring 14. After that, the user holds the handle 15 of the urine collection cup 1 and urinates into the urine collection cup 1 naturally and continuously;

[0039] Urine first flows into the lower urine storage chamber 6 through the No. 1 opening on the urine partition plate 2. As urine flows in, the lower urine storage chamber 6 is gradually filled. When the urine in the lower urine storage chamber 6 reaches a certain amount, the waterproof foam 8 floats up due to the buoyancy and the impact of urine backflow. The waterproof foam 8 pushes the protrusion at one end of the latex isolation plate 7 to move upward, and finally seals the No. 1 opening to prevent urine from continuing to enter the lower urine storage chamber 6, and also prevents the initial urine in the lower urine storage chamber 6 from overflowing into the upper urine storage chamber 5.

[0040] When urine continues to flow into the urine collection cup 1, since the No. 1 opening is sealed, the urine can only enter the upper urine storage cavity 5. When the urine height in the upper urine storage cavity 5 reaches the No. 2 opening 11, the middle urine naturally flows into the sample preservation tube 4 through the No. 2 opening 11 and the catheter 10. The preservation solution 13 in the sample preservation tube 4 mixes with the middle urine, which plays a role in preserving and stabilizing the urine sample.

[0041] If the amount of urine is too large and exceeds the capacity of the upper urine storage cavity 5 and the sample storage tube 4, the excess urine will be discharged through the overflow port 16 to prevent the urine from overflowing to the outside and keep the collection process clean;

[0042] When urine collection is completed, gently pull out the sample preservation tube 4, ensure that the cover of the sample preservation tube 4 is properly covered to prevent the sample from being contaminated during the inspection process, and send the covered sample preservation tube 4 to the laboratory for subsequent testing.
