Description

Technical Field

[0001] The utility model relates to the field of medical testing vessels, in particular to a portable anti-pollution urine sample collecting device. Background Art

[0002] Urinalysis, or urine test, is a method of testing urine for general properties, chemistry, and microscopy through visual inspection, physics, chemistry, microscopy, and instruments to achieve the purpose of disease prevention, diagnosis, monitoring, and prognosis. Urinalysis is widely used in clinical practice. Usually, the vessels used to collect urine samples are divided into urine cups and test tubes, which are placed at the window of the hospital laboratory. The patient takes the urine cup and fills it into the test tube for inspection. Since the urine cup and test tube are open, there is a possibility that the utensils and urine samples will be contaminated during the process of placement, taking, collection, and inspection. Moreover, the urine cups and test tubes are stacked separately, which makes the test window cluttered and congested, and increases the workload of medical workers to repeatedly add and sort.

[0003] The original intention of the design of the utility model is to improve the defects that the utensils and urine samples are easily contaminated during the above urine test process, ensure the reliability of the urine test results, and reduce unnecessary labor for medical workers.

[0004] The Chinese utility model patent with the announcement number CN216702571U discloses a collapsible sampling device for urine routine test samples, wherein the urine cup and the test tube are both retractable, and the bottom of the urine cup and the top of the test tube are connected together by threads, and the urine cup cover and the test tube cover are respectively arranged on the top of the urine cup and the bottom of the test tube. After the urine cup is unscrewed and discarded, the test tube cover at the bottom of the test tube needs to be unscrewed and then screwed into the test tube opening at the top of the test tube to seal the test tube. The device is mushroom-shaped after contraction, and although the volume is smaller than that in use, it is still not conducive to storage; the retractable test tube cannot observe the general properties of the urine sample during urine testing due to its surface texture, and the amount of urine sample cannot be intuitively read through the test tube scale; the device needs to be screwed in and out of the threaded joint at least three times when operating, which is relatively complicated; the device uses more materials than the non-retractable vessel, which is not conducive to cost control when it is widely used in clinical practice.

[0005] In summary, we urgently need to design a urine sample collection device that is more convenient, easy to store, low-cost, safe, hygienic and reliable. Utility Model Content

[0006] In order to overcome the above defects in the prior art and achieve the above objectives, the technical solutions adopted by the present utility model are as follows:

[0007] A portable anti-contamination urine sample collection device comprises a test tube, a limiting cover, and a urine collection cup. The folded urine collection cup is placed in the test tube, with its closed end facing the bottom of the test tube and its open end higher than the plane of the test tube mouth. The limiting cover covers the test tube mouth.

[0008] The retractable urine cup is opened to form a wide-mouth container shape, such as a cup shape, a bowl shape, a hemisphere shape, etc., and is folded to form a closed umbrella shape, which is approximately columnar, and has a size that can be placed in a test tube after being folded.

[0009] The bullet collecting urine cup comprises a bullet collecting frame and an envelope film, wherein the envelope film is attached to the bullet collecting frame. The bullet collecting frame can be in a shape of a mesh, a radial, a cross, a regular polygon, etc., with the main material being distributed in a centrally symmetrical pattern, so as to be easy to gather toward the center and to bounce to the surroundings.

[0010] The bullet receiving frame is made of elastic material, medical hard plastic, and good toughness, such as polystyrene (PS), polypropylene (PP), polyethylene (PP), polyvinyl chloride (PVC), etc.; the envelope film is made of flexible transparent material, relatively thin, medical soft plastic, synthetic rubber, latex, polymer material, with certain transparency and toughness, such as polyvinyl chloride (PVC), nitrile, medical latex, polyurethane, etc. The above materials can be comprehensively selected according to the requirements of this solution, processing difficulty, material cost and other factors.

[0011] Because the bullet collecting frame of the bullet collecting urine cup has a certain elasticity, when it is folded and placed in a test tube, the bullet collecting frame tends to expand outwards. This tendency causes the bullet collecting frame to press tightly against the inner wall of the test tube. The friction force generated by the pressure can ensure that the bullet collecting urine cup will not move in the test tube.

[0012] The opening end of the ammunition receiving frame is provided with a hand-held part and a guide part. The hand-held part and the guide part are integrally formed with the ammunition receiving frame, so as to ensure effective mechanical conduction. The shapes of the two parts are protruded during processing for easy use.

[0013] In specific implementation, the hand-held part is generally a handle, the shape of which is based on the ease with which a human hand can hold it, and the size of which is based on the ability to be stored in the limit cover after being folded and combined; the guide part is generally in the shape of a pointed mouth, which is convenient for the user to pour the urine sample in the urine cup into the test tube.

[0014] A sealing positioning belt is arranged on the inner side of the limiting cover near the cover opening end, which can be a thread, a buckle or the like.

[0015] Correspondingly, a sealing positioning groove is provided on the outer wall of the test tube near one end of the test tube opening, which cooperates with the sealing positioning belt of the limiting cover.

[0016] It should be noted that the reason why the limit cover needs to be limited is to ensure that when the limit cover seals the test tube mouth, there is a certain distance between the inner bottom surface of the cover and the plane of the test tube mouth. This distance is used to place the open end of the urine cup, so that after the patient opens the limit cover, he can clearly see and conveniently pinch the handle exposed at the test tube mouth.

[0017] The beneficial effects of the utility model are:

[0018] First, a collapsible and spring-openable urine cup is used. After collapsing, it can be put into a test tube. The test tube has a sealed lid, which effectively prevents the urine sample collection device from being contaminated during transportation, storage, and use. After the urine sample is poured into the test tube, the test tube is sealed, which also prevents the urine sample from being contaminated during the inspection process. Moreover, the entire collection device is only the size of a test tube. Compared with the cited patent, the size and shape are convenient for transportation and storage.

[0019] Second, a hand-held part is provided on the urine cup, and the limit cover is opened, and the hand-held part is exposed above the mouth of the test tube. Due to the elastic force of the collecting frame, the urine cup is automatically opened to a wide-mouth container shape when the test tube is taken out. The operator only needs to pinch the hand-held part to complete the actions of restoring the urine cup, retaining urine and pouring, and then seal the test tube. Therefore, the utility model is easy to operate, takes less time, and is convenient.

[0020] Third, compared with the cited patent, the utility model ensures the isolation between the operator and the device during the collection process because the contact time and contact area between the operator and the collection device are short.

[0021] Fourth, compared with the cited patent, the utility model has a simple structure, fewer covers, and only one test tube limiting cover, which is non-retractable, so less consumables.

[0022] Fifth, the utility model adopts a general test tube with scales on the outer wall. Compared with the cited patent, the amount of urine sample can be read intuitively and the general properties of the urine sample can be observed. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] [Example 1]

[0034] like Figure 1 As shown, a portable anti-contamination urine sample collection device comprises a test tube 1, a urine collection cup 2, and a limit cover 3. The folded urine collection cup 2 is placed in the test tube 1, with its closed end facing the bottom of the test tube and its open end higher than the test tube mouth plane.

[0035] The limiting cover 3 is in an open state, and the opening edge of the cover body is connected to the connecting belt 10 , and the other end of the connecting belt 10 is connected to the fixing ring 11 below the sealing positioning groove 9 on the outer wall of the test tube 1 .

[0036] like Figure 2 , Figure 3 , Figure 4 As shown, the ammunition receiving rack 4 of this embodiment is in a cross shape, and a pair of hand-holding parts 6 and a pair of guide parts 7 are respectively arranged opposite to each other at the four ends of the cross.

[0037] After the urine cup 2 is opened, it is in the shape of a wide-mouth container.

[0038] The collapsible urine cup 2 is folded into a closed umbrella shape, and the hand-held portion 6 and the guide portion 7 are located at the open end of the closed umbrella-shaped urine cup.

[0039] like Figure 5 As shown, a sealing positioning band 8 is arranged on the inner side of the limiting cover 3 near the cover opening end. The sealing positioning band 8 of this embodiment is a ring with a semicircular cross section.

[0040] A sealing positioning groove 9 is provided on the outer wall of the test tube 1 near one end of the test tube mouth. The sealing positioning groove 9 of the present embodiment is two upper and lower rings with semicircular cross-sections, and the cross-section of the upper ring is the same as the sealing positioning belt 8, the cross-section diameter of the lower ring is 1.5-2.5 times that of the upper ring, and the distance between the upper and lower rings is smaller than the diameter of the upper ring.

[0041] Since the test tube 1 and the limiting cover 3 are made of medical plastic and have a certain toughness, when the user presses the limiting cover 3 downward, the sealing positioning belt 8 passes through the upper ring due to the elastic deformation between it and the upper ring of the sealing positioning groove 9. Since the lower ring has a larger diameter and a higher protrusion, its elastic deformation is not enough to allow the sealing positioning belt 8 to pass through, so the sealing positioning belt 8 stays in the distance between the upper and lower rings of the sealing positioning groove 9.

[0042] Because the distance between the upper and lower rings is smaller than the diameter of the sealing positioning belt 8, the sealing positioning belt 8 is closely tangent to the sealing positioning groove 9, thereby achieving the purpose of sealing.

[0043] Lifting the limit cover 3 upwards is based on the same principle as pressing it downwards.

[0044] like Figure 5 As shown, in this embodiment, when the limiting cover 3 covers the test tube opening, the inner bottom surface thereof is limited to a distance of 8 mm from the plane of the test tube opening. The opening end of the urine collecting cup 2 protrudes 7 mm from the plane of the test tube opening, and a hand-held portion 6 and a flow guide portion 7 are disposed on the opening end.

[0045] In this embodiment: the outer diameter of the test tube is 20mm, and the total height including the cover is 116mm; after the urine cup is opened, the container diameter is about 50mm, the thickness of the bullet receiving frame is 0.8mm, the hand-held part is about a quadrilateral of 8mmX10mm, and the size of the guide part is about half of the hand-held part.

[0046] The bullet collecting frame of the bullet collecting urine cup of this embodiment is made of high-density polyethylene (HDPE), and the envelope film is made of polyvinyl chloride (PVC).

[0047]

Application process

[0048] Taking Example 1 as an example, the application process of the utility model is explained: the patient opens the limiting cover 3, pinches the hand-held part 6 with fingers and pulls out the urine cup 2, which automatically pops open to form a wide-mouth container, retains the middle part of the urine, and pours an appropriate amount of urine sample into the test tube 1 along the guide part 7, discards the urine cup 2, presses the limiting cover 3 to seal the test tube, and sends it for inspection.

[0049] It should be clear that the above detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
