Description

Technical Field

[0001] The present invention relates to the technical field of medical testing products, and in particular to a disease screening test tube with more accurate test results. Background Art

[0002] Test tubes are extremely commonly used testing auxiliary tools in medicine. Compared with going to the hospital for systematic sampling and testing, which requires a long time to get the test results, test tubes are easy to use. You can conduct preliminary screening for diseases at home, which is convenient for use. Simple initial examinations of diseases can also be conducted in hospitals, without the need for in-depth testing, which simplifies the testing steps. However, the test tubes currently on the market generally consist of a sampling cotton swab, a rubber-tipped dropper filled with reagents, and a test box. People need to use a sampling cotton swab to sample body fluids, feces, etc., put them into the rubber-tipped dropper for the reagents to mix, and then drip them into the test box to wait for the results. Although this method is faster than the in-depth testing in the hospital, the overall operation is still relatively complicated. The body fluids, feces, etc. dipped in it have odors, and the hands may be dirty during the operation, affecting people's experience of use. In addition, it is difficult for people to accurately control the amount of the reagents used during sampling and dripping, resulting in deviations in the final test results, which cannot meet people's testing needs.

DETAILED DESCRIPTION

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Please refer to Figures 1 to 8 The embodiment of the present invention provides a disease screening test tube with more accurate test results, including a test tube body 1 loaded with reagents, a sampling cotton swab 2 that can be inserted into the test tube body 1, and a sealing structure body 3 sleeved on the sampling cotton swab 2 and the cavity 11, wherein the test tube body 1 is formed with a cavity 11 for the sampling cotton swab 2 to insert and load reagents; a certain amount of structure body 4 is formed in the middle of the cavity 11 for the sampling cotton swab 2 to insert; the sealing structure body 3 includes a penetration piece 31 movably arranged in the cavity 11 and pressed by the lower end of the sampling cotton swab 2, and a sealing paper 32 arranged at the lower part of the cavity 11 and can be penetrated and punctured by the penetration piece 31, and at least one result display test paper 5 is arranged at one end of the cavity 11 away from the sealing paper 32.

[0032] After the sampling cotton swab 2 is dipped in the sample, it is inserted into the cavity 11 of the test tube body 1, and pressed against the quantitative structure body 4 to be guided by the quantitative structure body 4 and scrape off the excess sample on the sampling cotton swab 2, leaving a suitable amount of sample to enter the reagent for mixed detection. At the same time, the penetration member 31 is pressed against the inner wall of the cavity 11, so that the reagent in the cavity 11 is divided into different parts by the penetration member 31, and the penetration member 31 is pressed against the sealing paper 32 by the sampling cotton swab 2, so that the sealing paper 32 is punctured, and the appropriate amount of reagent of the mixed appropriate amount of sample under the penetration member 31 is entered into the cavity 11 with the result display test paper 5 for detection, thereby achieving the purpose of precise quantity control and effectively improving the accuracy of the test tube detection. After the sampling cotton swab 2 is pressed down, the sealing structure body 3 seals the cavity 11, thereby preventing the leakage of reagents and affecting the detection results and the leakage of samples to dirty people's hands, or the leakage of odors during the shaking of the test tube body 1, achieving the effect of deodorization.

[0033] Regarding the specific structural arrangement of the chamber 11, Figures 4 to 5 as well as Figure 8 As shown, the cavity 11 is U-shaped as a whole, and the sealing paper 32 is arranged at the bottom of one end of the U-shaped structure. The sealing paper 32 separates the two ends of the cavity 11U-shaped, so as to prevent the unsampled and mixed reagents from contaminating the result display test paper 5, thereby affecting the test results. The U-shaped structural setting of the cavity 11 is also conducive to the subsequent penetration member 31 to pierce the sealing paper 32, so that an appropriate amount of reagent can be guided through the U-shaped structure to flow to the result display test paper 5 for result display (one bar or two bars). The specific structure for allowing the reagent to flow at the bottom of the U-shaped cavity 11 can be set according to actual conditions, so no specific restrictions are made in this embodiment.

[0034] Regarding the specific structural arrangement of the penetration member 31, Figures 2 to 4 as well as Figure 7 As shown, the penetration member 31 is T-shaped as a whole, and includes a transverse portion 311 that extends transversely as a whole and presses against the cavity 11, a longitudinal portion 312 integrally formed in the middle of the lower end surface of the transverse portion 311, a pointed portion 313 integrally formed at the lower end of the longitudinal portion 312, and a plurality of pointed teeth 314 evenly arranged on the outer side of the lower end surface of the pointed portion. The bottom end of the sampling cotton swab 2 is pressed against the transverse portion 311 of the penetration piece 31 and drives the penetration piece 31 to be pressed downward, so that the sharp teeth 314 of the penetration piece 31 are pressed against the sealing paper 32, and the sealing paper 32 is pierced, so that the reagent mixed with the appropriate amount of sample enters the bottom of the cavity 11 with the penetration piece 31, and the excess reagent is blocked by the transverse portion 311 of the penetration piece 31 above the penetration piece 31, thereby achieving the purpose of quantifying the amount of reagent entering the result display test paper 5, thereby achieving precise control of the amount, effectively improving the accuracy of the test tube detection, and the operation is simple and convenient, eliminating the need for conventional operations that require the user to use a dropper to drip an appropriate amount on the test box, saving time and effort, and facilitating use.

[0035] The specific method of separating the appropriate amount of reagent and the excess reagent of the mixed sample by the penetration member 31 is as follows: Figures 4 to 5 as well as Figure 8As shown, the bottom of the cavity 11 near the end of the sealing paper 32 is formed with a first sealed cavity 12 for the transverse portion 311 of the penetration member 31 to move, and a second sealed cavity 13 connected to the lower end of the first sealed cavity 12 and for the longitudinal portion 312 and the pointed portion 313 of the penetration member 31 to move, and the sealing paper 32 is arranged at the bottom of the second sealed cavity 13. Under the pressure of the sampling cotton swab 2, the transverse portion 311 of the penetration member 31 enters the first sealed cavity 12 and presses against the inner wall of the first sealed cavity 12, so that the reagent mixed with the sample in the first sealed cavity 12 is separated from the reagent at the upper end of the transverse portion 311, and the reagent in the first sealed cavity 12 flows downward along with the longitudinal portion 312, and the pointed portion 313 presses against the side wall of the second sealed cavity 13, and after the sealing paper 32 is punctured, an appropriate amount of reagent flows through the U-shaped structure of the cavity 11 to the position of the cavity 11 with the result display test paper 5, and is detected by the result display test paper 5 to display the result.

[0036] The specific method for the reagent in the first sealed cavity 12 to follow the penetration member 31 into the containing cavity 11 is to have the result displayed on one end of the test paper 5, such as Figures 2 to 4 as well as Figure 7 As shown, the diameter of the longitudinal portion 312 is smaller than the diameter of the pointed portion 313, so that the reagent separated in the first sealed cavity 12 can enter the end of the result display test paper 5 in the cavity 11 through the gap between the longitudinal portion 312 and the first sealed cavity 12 and the second sealed cavity 13 after the pointed portion 313 is pressed against the bottom end of the second sealed cavity 13, thereby completing the detection and effectively and precisely controlling the reagent entering the result display test paper 5, thereby effectively improving the accuracy of the test tube detection.

[0037] Preferably, in order to prevent the penetration member 31 from shifting in the cavity 11, Figures 4 to 5 as well as Figure 8 As shown, the upper end of the first sealing cavity 12 is symmetrically provided with a through limit block 121 which is overall in the shape of a " " and presses against the upper end surface of the transverse portion 311. By using the through limit block 121 to press against the upper end surface of the transverse portion 311, the through member 31 is effectively prevented from shifting in the cavity 11.

[0038] Preferably, in order to enable the sampling cotton swab 2 to better drive the penetration member 31 to move downward, as shown in FIG. Figures 2 to 4 as well as Figure 7As shown, a pressing and pushing groove 3112 is formed in the middle of the upper end surface of the transverse portion 311, which is overall conical and matches the lower end surface of the sampling cotton swab 2, so that it is more matched with the lower end of the sampling cotton swab 2. The conical structure can guide the lower end of the sampling cotton swab 2, so that the lower end of the sampling cotton swab 2 can be more easily pressed against the middle of the transverse portion 311 under the guiding action, and force is applied to the through-piece 31, thereby improving the pressing efficiency of the sampling cotton swab 2.

[0039] Regarding the specific structural setting of the sampling cotton swab 2, as shown in FIG. Figures 2 to 6 As shown, the sampling cotton swab 2 includes a cotton swab handle 21 and a cotton swab body 22 connected to the lower end of the cotton swab handle 21. The cotton swab handle 21 is provided to facilitate people to grasp and prevent people's hands from getting dirty while dipping the sample. The cotton swab body 22 is used to dip the sample.

[0040] The specific method of the sealing structure body 3 sealing the cavity 11 is as follows: Figures 2 to 5 As shown, the sealing structure body 3 also includes a first sealing ring 33 sleeved on the cotton swab handle 21, a second sealing ring 34 sleeved between the middle of the cotton swab body 22 and the quantitative structure body 4, a third sealing ring 35 sleeved on the outside of the transverse portion 311 of the penetration member 31, and a fourth sealing ring 36 sleeved on the outside of the tail end of the longitudinal portion 312 of the penetration member 31. When the cotton swab handle 21 is inserted into the cavity 11, the first sealing ring 33 abuts against the inner wall of the upper part of the cavity 11, thereby isolating the cavity 11 from the outside for sealing, and the second sealing ring 34 abuts against the inner wall of the radial scraping portion 42 when the cotton swab body 22 is inserted into the radial scraping portion 42, thereby separating the reagent with excess sample fusion above the quantitative structure body 4 and the reagent mixed with an appropriate amount of sample below the quantitative structure body 4, thereby improving the detection accuracy. The third sealing ring 35 is pressed against the inner wall of the first sealed cavity 12 when the transverse portion 311 of the penetration member 31 is embedded in the first sealed cavity 12, so that only the amount of reagent in the first sealed cavity 12 that has been mixed with an appropriate amount of sample at the upper end of the first sealed cavity 12 can enter the end of the cavity 11 with the result display test paper 5, thereby accurately controlling the amount of the test paper 5 entering the result display, further improving the accuracy of the test tube detection. The fourth sealing ring 36 is pressed against the inner wall of the second sealed cavity 13 when the tail end of the longitudinal portion 312 of the penetration member 31 is embedded in the second sealed cavity 13, thereby limiting the position of the penetration member 31 to move, so that the tail end of the penetration member 31 can better pierce the sealing paper 32 to allow the reagent in the first sealed cavity 12 to enter the end of the cavity 11 with the result display test paper 5, thereby improving the accuracy of the test tube detection.

[0041] The specific manner in which the first sealing ring 33 and the second sealing ring 34 are arranged on the sampling cotton swab 2 is as follows: Figures 3 to 6As shown, the cotton swab handle 21 is provided with a first sealing installation groove 211 which is recessed inwards and for installing the first sealing ring 33. The first sealing ring 33 is correspondingly sleeved in the first sealing installation groove 211 to prevent the first sealing ring 33 from shifting, thereby improving the sealing accuracy of the sealing structure body 3; the cotton swab body 22 is provided with a second sealing installation groove 221 which is recessed inwards and for installing the second sealing ring 34. The second sealing ring 34 is correspondingly sleeved in the second sealing installation groove 221 to prevent the second sealing ring 34 from shifting, thereby improving the sealing accuracy of the sealing structure body 3.

[0042] The specific manner in which the third sealing ring 35 and the fourth sealing ring 36 are arranged on the penetration member 31 is as follows: Figures 2 to 5 as well as Figure 7 As shown, a third sealing installation groove 3111 which is recessed inwards and is provided on the outer side of the transverse portion 311 of the penetration piece 31, and a third sealing ring 35 is installed therein. The third sealing ring 35 is correspondingly sleeved in the third sealing installation groove 3111, thereby preventing the third sealing ring 35 from shifting, and further improving the sealing accuracy of the sealing structure body 3; a fourth sealing installation groove 3121 which is recessed inwards and is provided on the outer side of the tail end of the longitudinal portion 312 of the penetration piece 31, and a fourth sealing ring 36 is installed therein, and the fourth sealing ring 36 is correspondingly sleeved in the fourth sealing installation groove 3121, thereby preventing the fourth sealing ring 36 from shifting, and effectively ensuring the accuracy of the penetration piece 31 in puncturing the sealing paper 32.

[0043] Preferably, Figures 4 to 6 as well as Figure 8 As shown, a sealing ring is also provided on the side of the sealing paper 32 , and the outer side of the sealing paper 32 is tightly sealed on the sealing ring, and the sealing ring is pressed by the structure in the cavity 11 , thereby limiting the position of the sealing paper 32 to ensure the separation effect of the sealing paper 32 .

[0044] For the specific structure setting of quantitative structure ontology 4, such as Figures 4 to 6 as well as Figure 8As shown, the quantitative structural body 4 includes an inclined guide scratching portion 41 formed inside the cavity 11 and extending obliquely downward into the cavity 11, and a radial scratching portion 42 integrally formed below the inclined guide scratching portion 41 and extending vertically downward. After dipping the sample, the sampling cotton swab 2 is inserted into the cavity 11 of the test tube body 1 and pressed against the inclined guide scratching portion 41. Under the inclined guiding action of the inclined guide scratching portion 41, the sampling cotton swab 2 moves toward the middle of the inclined guide scratching portion 41 and extends into the inclined guide scratching portion 41. The excess sample on the outside of the sampling cotton swab 2 is scratched away by the inclined surface of the inclined guide scratching portion 41. After being guided and scratched by the inclined guide scratching portion 41, the sampling cotton swab 2 enters the radial scratching portion 42 and is scratched again by the radial scratching portion 42 perpendicular to the radial direction, leaving only a suitable amount of sample to enter the reagent for mixed detection, thereby further improving the accuracy of the test tube detection.

[0045] Preferably, Figures 3 to 6 As shown, the lower end of the cotton swab body 22 is threaded or wavy, which increases the contact area between the lower end of the cotton swab body and the sample, thereby making it easier for the cotton swab body 22 to dip into the sample, thereby improving the sampling efficiency of the sampling cotton swab 2.

[0046] Preferably, Figures 4 to 6 as well as Figure 8 As shown, the diameter of the cotton swab body 22 matches the diameters of the radial scraping portion 42 and the inclined guide scraping portion 41, so that the sample dipped on the cotton swab body 22 is more easily scraped away by the inclined guide scraping portion 41, leaving only a suitable amount of sample to enter the reagent pair for mixed detection, further improving the accuracy of the test tube detection.

[0047] Preferably, Figures 4 to 6 as well as Figure 8 As shown, the height of the cotton swab handle 21 is higher than the height of the test tube body 1 , so that it is convenient for people to grasp the cotton swab handle 21 and insert the cotton swab body 22 into the test tube body 1 .

[0048] Preferably, Figures 4 to 6 as well as Figure 8 As shown, in order to prevent the sampling cotton swab 2 from excessively extending into the inclined guide scratch portion 41, the diameter of the cotton swab handle 21 is larger than the diameter of the cotton swab body 22, so that the cotton swab handle 21 will be stuck outside the inclined guide scratch portion 41 and cannot enter the inclined guide scratch portion 41, thereby preventing the sampling cotton swab 2 from excessively extending into the inclined guide scratch portion 41, leaving only a suitable amount of sample to enter the reagent for mixed detection, further improving the accuracy of the test tube detection.

[0049] Preferably, Figures 3 to 6 as well as Figure 8As shown, in order to further prevent the sampling cotton swab 2 from excessively extending into the inclined guide scratch portion 41, a scratching and pressing member 23 is further provided between the cotton swab handle 21 and the cotton swab body 22, and the diameter of the scratching and pressing member 23 is larger than the diameter of the inclined guide scratch portion 41. When the sampling cotton swab 2 penetrates into the cavity 11, the scratching and pressing member 23 will be stuck outside the inclined guide scratch portion 41 and cannot enter the inclined guide scratch portion 41, thereby preventing the sampling cotton swab 2 from excessively extending into the inclined guide scratch portion 41, leaving only a suitable amount of sample to enter the reagent for mixed detection, thereby further improving the accuracy of the test tube detection.

[0050] Preferably, Figures 4 to 6 as well as Figure 8 As shown, in order to prevent the sampling cotton swab 2 from deviating in the cavity 11 and causing inaccurate testing, the diameter of the cotton swab handle 21 matches the diameter of the cavity 11, so that the cotton swab handle 21 is limited by the cavity 11 when entering the cavity 11, thereby effectively preventing the cotton swab body 22 dipped in the sample from deviating in the cavity 11 and causing inaccurate testing.

[0051] Regarding the sealing method of the test tube body 1 when not in use, Figure 1 , Figures 4 to 5 as well as Figure 8 As shown, the disease screening test tube also includes a safety cover 6 that can be covered on the test tube body 1, and the safety cover 6 is provided with a handle channel 61 for the cotton swab handle 21 of the sampling cotton swab 2 to be correspondingly embedded, and a first limiting surface 611 is formed on the upper end surface of the handle channel 61 and extends obliquely from the upper outside to the lower inside, and a second limiting surface 212 is formed on the outer side wall of the upper end of the cotton swab handle 21 and extends obliquely from the upper outside to the lower inside and matches the first limiting surface 611. When the disease screening test tube is not needed, the safety cover 6 is covered on the test tube body 1, and the cotton swab handle 21 of the sampling cotton swab 2 is inserted into the handle channel 61 until the second limiting surface 212 on the cotton swab handle 21 is attached to the first limiting surface 611 on the handle channel 61. Due to the structure that the first limiting surface 611 and the second limiting surface 212 extend obliquely from the upper outside to the lower inside, the cotton swab handle 21 is stuck on the first limiting surface 611, which effectively prevents the sampling cotton swab 2 from accidentally touching and pressing down on the through-piece 31, so that the reagent without the sample dipped enters the result display test paper 5, resulting in the invalidity of the disease screening test tube.

[0052] Preferably, Figures 4 to 5 as well as Figure 8As shown, a first sealing guide surface 15 extending obliquely from the upper outside to the lower inside is formed at the upper part of the cavity 11 where the sampling cotton swab 2 is inserted. When the first sealing ring 33 follows the cotton swab handle 21 to be inserted into the cavity 11, it contacts the first sealing guide surface 15 first and is guided by the inclined structure of the first sealing guide surface 15, so that it is easier to enter the cavity 11 and press against the side wall of the cavity 11, thereby achieving the sealing of the cavity 11 to prevent the leakage of the reagent and seal the odor.

[0053] In order to make it easier for people to observe the result display test paper 5, Figure 3 As shown, a visual window 14 is provided at one end of the test tube body 1 close to the result display test paper 5, through which the result of the result display test paper 5 can be directly observed, which is beneficial to people's use and improves people's use experience.

[0054] It should be noted that the disease screening test tube with more accurate test results disclosed in the present invention is an improvement on the specific structure, and the specific control method is not the innovation of the present invention.
