Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pathological examination device, and more particularly to a single-use disposable urine examination device.

[0002]

[Prior art]

 In clinical tests, test strips or reagent strips must be used to identify patients, especially for the presence of blood, bilirubin, urobilinogen, glucose, protein, nitrite and calcium. Examine the urine. From the results of such tests, the physician will preliminarily and quickly diagnose the problems of the examined patient, and then prepare a more thorough examination tailored to the patient using more sophisticated equipment and instruments. can do. In order for patients to monitor and control their illness in a timely manner, physicians sometimes teach patients how to test their urine using test strips so that patients can work effectively with them. Enables doctors to effectively observe, examine, and diagnose patients. For example, in the case of diabetes, a commonly known disease, physicians often instruct diabetics to use their test strips to test their own urine for glucose levels, If a sickness occurs, instruct the physician to immediately contact a physician for treatment or emergency treatment.

[0003] Reagent strips are already commercially available, and those that are generally available are capable of diagnosing various medical conditions related to components in urine and performing multifunctional tests. Each test strip comprises a plastic strip in which the tidbits of the substance that react with the various types of components in urine and produce a color change are ordered. The results of the test, if any, are indicated via a color change by comparing the color change of the fragment to a standard color table (or a standard color table or swatch). Therefore, commercially available reagent strips usually include a standard color change comparison table in the package for comparing color changes. Discoloration on urinalysis indicates a condition in the patient that should be further diagnosed and treated further.

[0004]

[Problems to be solved by the invention]

 Commercially available reagent strips are exclusively for use in clinics and hospitals. Therefore, they are usually sold in bundles of 100 strips, and they usually contain a desiccant in the package to prevent the strips from being affected by moisture, thereby providing a shelf life (or expiration date). ). In any case, this type of packaging is not suitable for personal or family use. That is because the patient only needs to use about one strip per day. For 100 strips, it will take at least a few months from opening the pack to using it up. Also, each time one strip is taken out for use, the rest will have the opportunity to be affected by atmospheric moisture, and therefore, after several uses, before the entire pack is used up. The remaining strips may already be unusable due to moisture or the results obtained therefrom may no longer be correct.

In order to check the results, a urine-soaked strip must be carried for comparison with a standard discoloration comparison table. The standard discoloration comparison sheet gives a level (or content or concentration) analysis result on the amount of the component in the urine sample, and it is possible to diagnose a patient based on the result. This type of work always has the potential to pollute the environment. It is because urine is easily spilled (or scattered) everywhere.

[0006] It is an object of the new invention to provide a disposable urinalysis device. The structure of the new invention is simple, easy to manufacture and at low manufacturing cost. A more important aspect of using the new device is to avoid contamination with conventional urine, as described above.

[0007]

[Means for Solving the Problems]

 The novel invention for urinalysis includes a transparent tube (or tube) made of transparent resin, a tube cap, and a standard color change comparison table.

[0008] The transparent tube is also a narrower and longer main tube body: at its upper end there is a collecting part with a larger diameter for collecting excess (or extra) urine. An engaging portion of the main tube body having a step shape for engaging with the cap is provided along a periphery of the opening of the collecting portion; an inner diameter of the engaging portion of the main tube body is provided; Includes main tube body smaller than outer diameter.

[0009] The outer portion of the cap has a long, flat handle used to grip and rotate the cap, and the inside of the cap is formed with a slit to hold the reagent strip in place. In addition, a step-shaped engaging portion that engages with the engaging portion of the main tube body is provided on the periphery of the cap, and the outer diameter of the engaging portion of the cap and the engaging portion of the main tube body are provided. The inner diameter of the cap is approximately the same size so that the engagement portion of the cap can engage with the engagement portion of the main tube body in a sliding fit.

[0010] The standard discoloration comparison table is similar to the conventional one, and includes a color chart of the test components (for example, represented by a plurality of small colored squares in the standard discoloration comparison table). In the present invention, the color chart is printed directly on the body of the transparent tube.

[0011] In another aspect of the novel invention, the inner upper end of the cap is closed with a perforated annular plate to form a chamber for containing a desiccant. The desiccant will extend the shelf life of the reagent strip stored in the device. In yet another aspect, the handle of the cap can be eliminated, and the function of the handle instead replaced by raising (or embossing) the outer peripheral surface of the cap to form a pattern of parallel grooves. Can play.

In another aspect of the novel invention, the discoloration comparison table can be pre-printed on a transparent sheet and then glued to the outer surface of the body of the transparent tube. The transparent sheet may be, for example, a transparent paper or paper, or a transparent plastic sheet (for example, a film). In another similar embodiment, a preprinted color change table can be attached to the inner peripheral surface of the body of the transparent tube.

[0013] Since the new invention is a disposable urinalysis device formed of recyclable resin that can be recycled again, it will not pose any environmental problems. Since the analysis is performed in a transparent tube, it does not have the disadvantage that urine will drip somewhere. Also, because newly constructed devices are individually sealed and packaged, unlike conventional packaging, strips are less likely to degrade before a single box of strips is completely used, and can be used by individuals and families. It is convenient to use.

By reading the following description with reference to the accompanying drawings, those skilled in the art can clearly understand the objects, features and advantages of the present invention.

[Embodiment of the invention]

 Referring to FIG. 1, FIG. 1 shows a conventional reagent strip (5), and the same type of reagent strip is used in the present invention. The strip is made of plastic, on which pieces of test substance (501 ... 510) are placed. The test substances (501 ... 510) react with various components in the urine and the result of the test is indicated by a color change. Since the reagent strip itself is not a new invention requiring proprietary rights, its technical features will not be described in detail here.

FIGS. 2A and 2B show the configuration of the components of the urine test container (601) and its cap (602). The urine test container (601) and cap (602) together form a complete container; the outside of the container is wrapped with a standard discoloration comparison table. The container contains 100 reagent strips. Inside the cap is a chamber (or small chamber) containing a desiccant. This type of packaging is a practice in which the frequency of use (or consumption) of the strip is such that the strip can be used up in a very short time after opening the package but before the strip inside it becomes useless. It is perfect for use in places or hospitals. To protect the strip from the effects of moisture, the opening in the cap is covered with a perforated plate, thereby forming an inner chamber for the placement of the desiccant.

FIG. 3 shows the layout of a standard discoloration comparison table, in which the letters in the columns indicate the components in the urine to be examined or diagnosed and from the urine-soaked strip. The time required to determine the result is shown. Each row indicates a possible color change for each component item so tested, and different colors indicate different levels (or concentrations) of the test component present in the urine sample. For example, the one shown at the top corresponds to a test for the presence of leukocytes in urine and takes about 2 minutes; on the right are five different color patterns, each with the following results: negative (0), Shows trace (15), small (70), medium (125) and large (500). The diagnostic item at the bottom indicates that you need to wait 45 seconds after soaking urine to test for glucose, with six standard color patterns shown on the right, each Approximate milligrams of sugar per 1/10 liter of urine are shown. The results are divided into negative, small, 250 (+), 500 (++), 1000 (+++) and 2000 (+++++). The color change comparison table is also used to compare with other test items (eg, nitrite, urobilinogen, protein, pH, blood, specific gravity, ketone and bilirubin). The discoloration comparison table is a conventional technique and will not be described in detail herein.

FIG. 4 shows a novel invention designed as a urine test device (1). The urinalysis device (1) includes a transparent tube (2) made of transparent resin, a cap (3) and a color change standard comparison table (4). In the figure, only a part of the discoloration chart is shown. The entire discoloration comparison table is the same as that shown in FIG.

The transparent tube (2) includes a narrower (or smaller diameter) and longer main tube body (201): at its upper end, more for collecting excess urine. A collecting portion (202) having a large diameter is provided; an engaging portion (203) of the main tube body is provided along an opening of the collecting portion, the engaging portion being a step-shaped engagement with the cap; The inner diameter of the engaging part (203) of the main tube body is smaller than the outer diameter of the cap.

As shown in FIGS. 4 and 5, the outer portion of the cap (3) has a long, flat handle (301) used to grip and rotate the cap (3). FIG. 6 shows the internal structure of the cap (3). The internal structure of the cap (3) has a slit (302) for fixing the reagent strip in place.

Referring again to FIG. 4, the cap (3) is provided with a step-shaped engaging portion (303), and the cap (3) is provided with the collecting portion (202) of the transparent tube (2) and the collecting portion (202). Engage at the edge. The outer diameter of the engaging part (303) of the cap is approximately the same as the inner diameter of the engaging part (203) of the joint part of the main tube body, so that the engaging part (303) becomes transparent tube (303). It can be engaged with the engagement part (203) of the main body in 2) by sliding fit.

The standard discoloration comparison table is similar to the conventional one, which also indicates the level (or concentration) with respect to the amount of the component to be tested. The standard discoloration comparison chart is printed on the body of the transparent main tube (201).

FIG. 6 shows an embodiment of the novel invention. Inside the cap (3) is a chamber containing a desiccant to extend the shelf life (or shelf life) of the reagent strip stored in the test device. The chamber containing the desiccant is formed by a perforated annular plate (304) provided between the inner upper end of the cap (3) and the opening.

In another aspect, the handle of the cap (3) of the inspection device (1) can be eliminated, and a pattern of parallel grooves (not shown) designed to perform the function of the handle instead. The handle can be replaced by raising (or embossing) the outer peripheral surface of the cap so that a groove is formed.

In another aspect of the novel invention, the color change chart can be pre-printed on a transparent sheet and then glued to the outer surface of the body of the transparent tube. In a similar embodiment, a transparent sheet (eg, film) of a pre-printed discoloration diagram can be attached to the inner peripheral surface of the body of the transparent tube.

FIG. 7 shows an embodiment of the novel assembled device for urinalysis. The figure shows a state where the reagent strip (5) has been inserted.

[0027] The novel invention of a urine reagent strip testing device is intended for use as a single-use disposable, regardless of the fact that the product contains a desiccant to further extend shelf life. The devices also employ individually sealed packaging, as they are designed to be used. Products are sold individually packaged, which is convenient for personal or family use.

The method of using the novel device of the present invention for a urine reagent strip test device is as follows: after unpacking, remove the cap with the reagent strip attached, wet the strip with urine and allow the urine to drain. Dip into the strip to ensure complete coverage, then return the reagent strip to the clear tube and close the cap, thereby locking the urine from dripping. After the time specified for each test item has elapsed, twist the handle to check whether the test object (or test substance) (501 to 510) has changed color. If discolored, read the closest matching color for each discolored item and record the discoloration so that the physician can later examine and diagnose the patient's condition and treat the patient. I do. The test device can then be discarded after each test. As the new inventions are made of recyclable materials, they are collected and recycled for further use, so that they minimize environmental pollution.
