Description

Technical Field

[0001] The utility model relates to the field of concentration detection, in particular to a disinfectant concentration detection device. Background Art

[0002] Iodine tincture disinfectant and 84 disinfectant are common types of disinfectants, which can effectively kill microorganisms such as bacteria and viruses. They are often used in medical institutions, laboratories, and daily disinfection of households for disinfection and infection prevention. In order to ensure the disinfection effect and ensure that the disinfectant has sufficient active ingredients and is safe to use, the concentration of the disinfectant is generally tested. At present, there are many ways to detect disinfectants, such as optical methods, electrochemical methods, spectrophotometry, chemical reaction methods, and test paper colorimetry. Among them, the test paper colorimetry is widely used because of its simple operation, convenience, speed, and low price. At present, when the test paper colorimetry is detected, the process is to first take out the test paper and immerse it in the disinfectant for a while, then wait for a while and compare it with the standard color card under natural light. The concentration shown on the corresponding standard color block is the effective concentration of the disinfectant. In the above process, when the test personnel compare the test paper with the standard colorimetric card, they need to first take it out of the disinfectant and move it close to the colorimetric card, or move the colorimetric card close to the test paper for comparison. In this process, the disinfectant soaked on the test paper can easily drip onto the desktop or other locations. In addition, it is inconvenient to repeatedly take and put the colorimetric card, and the testing process is not neat. In particular, directly inserting the test paper into the disinfectant bottle is not only inconvenient, but when the disinfectant level is very low, it is sometimes difficult for the test paper to contact the disinfectant. The most common method is to pour the disinfectant into other containers and then soak the test paper in the disinfectant. Obviously, this increases the cumbersomeness of the operation, and the container must be cleaned separately after the test. Utility Model Content

[0003] At present, the test paper colorimetric method has a cumbersome detection process, and the disinfectant soaked on the test paper can easily drip to other places, which is not neat. At the same time, when the test paper is soaked in disinfectant, when there is little disinfectant in the disinfectant bottle so that the test paper cannot contact the disinfectant, other utensils are needed, which further increases the cumbersomeness. After completion, the utensils need to be cleaned separately, which increases the operation steps. At least one purpose and one aspect of the present application can solve the above problems, and a disinfectant concentration detection device is specifically designed, and the technical solution adopted is:

[0004] A disinfectant concentration detection device, comprising:

[0005] The shell has a channel inside, the channel is used to place the test paper, the channel extends to both ends of the shell and is open at both ends, and a transparent window is provided on the shell body corresponding to the channel;

[0006] A liquid storage component is arranged at one end of the housing and has a liquid storage cavity therein for containing disinfectant, the liquid storage cavity being communicated with the channel;

[0007] A convex colorimetric area is arranged on the side of the shell, and the length of the colorimetric area is shorter than the length of the transparent window.

[0008] Preferably, the liquid storage component includes a rubber ball, one side of the rubber ball is connected to a straw, and the other side symmetrically connected to the rubber ball is detachably connected to a connecting pipe, the connecting pipe is connected to the end of the shell through the liquid storage tank, and manual switch valves are respectively provided on the straw and the connecting pipe.

[0009] Preferably, the rubber ball is transparent rubber.

[0010] Preferably, the transparent window comprises: an installation opening, which is arranged at a corresponding channel of the shell body of the shell, and a transparent plate is sealed and installed on the installation opening.

[0011] Preferably, a card slot is provided around the edge of the installation opening, a flexible sealing pad is provided in the card slot, and the transparent plate is embedded in the card slot.

[0012] Preferably, the transparent plate is transparent plastic or transparent glass.

[0013] Preferably, the color comparison area includes a square block protruding from the side of the shell, the square block and the shell are an integrated structure, and different color blocks are sprayed on the square block.

[0014] Preferably, the colorimetric area comprises a square block protruding from the side of the housing, a receiving cavity is provided in the square block, a colorimetric card is placed in the receiving cavity, the upper surface of the receiving cavity is hollowed out, and one end of the receiving cavity is open.

[0015] Preferably, the housing and the colorimetric area are both made of plastic.

[0016] The utility model has the following technical effects through the above technical solution:

[0017] 1. This detection device has centralized liquid collection and detection functions. The rubber ball absorbs the liquid and discharges it into the liquid storage tank. The test paper passes through the channel and one end extends into the liquid storage tank to realize direct liquid collection and detection functions. At the same time, a colorimetric area is directly set on the outer shell. The color-developed test paper is directly compared with the colorimetric area. There is no need to repeatedly take and put the colorimetric card. At the same time, it also avoids the problem of excess disinfectant on the test paper dripping to other locations. The whole operation is neat and convenient.

[0018] 2. When there is less disinfectant, the straw on the rubber ball can be directly inserted into the disinfectant bottle to absorb the liquid without the help of other utensils, which greatly facilitates the operator's operation.

[0019] 3. The opening at one end of the channel of the shell can be used to replace new test paper at any time, so that other structures except the test paper can be reused repeatedly.

[0020] 4. The rubber ball and its connection structure cooperate with the channel structure to facilitate the detection of the concentrations of different types of disinfectants. That is, the rubber ball absorbs different liquids and replaces new test papers to complete the detection of the concentrations of different types of disinfectants. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] like Figure 1-4As shown, a disinfectant concentration detection device includes a shell 1, a liquid storage component 4 and a colorimetric area 3. The shell 1 is a rectangular shell 1, and a channel 5 is provided inside the shell 1. The channel 5 is arranged along the length direction of the shell 1. The channel 5 is mainly used to place the test paper 6. The channel 5 extends to both ends of the shell 1 and opens at both ends of the shell 1. The left end of the shell 1 is connected with a liquid storage component 4, and the liquid storage component 4 has a liquid storage cavity inside, which is used to hold the disinfectant. The liquid storage cavity is connected to the channel 5. A transparent window 2 is provided on the shell body of the shell 1 at a position corresponding to the channel 5. Correspondingly, the transparent window 2 is rectangular. The color development of the test paper 6 after being soaked in the disinfectant is observed through the transparent window 2, and it is compared with the colorimetric area 3 at the same time, so as to detect the concentration of the disinfectant. In order to ensure that all colors of the colorimetric area 3 can be compared with the test paper 6, the length of the above-mentioned colorimetric area 3 is less than the length of the transparent window 2.

[0029] Furthermore, the specific structure of the liquid storage component 4 includes a rubber ball 403, one side of the rubber ball 403 is connected to a straw 404, and the other side symmetrical to it is detachably connected to a connecting tube 402, and the connecting tube 402 is connected to the end of the shell 1 through the liquid storage tank 401. The detachable connection between the connecting tube 402 and the rubber ball 403 specifically adopts the current conventional form, that is, the connecting tube 402 is a plastic hard tube or a metal tube that has been treated with anti-corrosion, which is inserted into the rubber ball 403 and is tightly sealed by tying wire. The purpose of this arrangement is mainly to facilitate the disassembly of the rubber ball 403 and the connecting tube 402, and then to facilitate the replacement of the rubber ball 403 (because the rubber ball 403 may be corroded and damaged after long-term use). In order to facilitate the control of the liquid inlet and outlet of the rubber ball 403, manual switch valves 405 are respectively provided on the straw 404 and the connecting tube 402 to manually control the liquid inlet and outlet on both sides of the rubber ball 403.

[0030] It should be noted that the volume of the rubber ball 403 is smaller than the volume of the liquid storage tank 401 , that is, when the liquid in the rubber ball 403 is discharged into the liquid storage tank 401 , the height of the liquid is smaller than the height of the top of the liquid storage tank 401 .

[0031] Alternatively, the liquid storage component 4 can also be replaced by a conventional water tank with a liquid injection port, which is fixed at one end of the shell 1. When testing is required, the disinfectant is poured into the water tank through the liquid injection port, and then the test paper 6 penetrates into the disinfectant in the water tank.

[0032] Furthermore, the transparent window 2 specifically includes an installation opening 204, which is rectangular. The installation opening 204 is arranged at the shell body of the outer shell 1 at the corresponding channel 5. The installation opening 204 is sealed with a transparent plate 203. The transparent plate 203 here can be made of transparent plastic and transparent glass. The transparent plate 203 is mainly for the convenience of the detection personnel to observe the color of the internal detection reagent after color development.

[0033] Furthermore, after the detection reagent is soaked in disinfectant, the disinfectant on the detection reagent will inevitably wet the inner wall of the shell 1, and gradually a small amount of disinfectant will inevitably seep out from the observation window. In order to avoid a small amount of disinfectant from seeping out from here, the above-mentioned transparent window 2 is specifically configured as follows, that is, a card groove 201 is provided around the edge of the installation port 204, a flexible sealing gasket 202 is provided in the card groove 201, and a transparent plate 203 is embedded in the card groove 201, and the flexible sealing gasket 202 achieves sealing by its own deformation.

[0034] In one embodiment, Figure 5 As shown, the color comparison area 3 can be configured as follows: comprising a square block 301 protruding from the upper side of the housing 1 , the square block 301 and the housing 1 are an integrated structure, and different color blocks 304 are sprayed on the square block 301 .

[0035] In one embodiment, Figure 1 As shown, the colorimetric area 3 may also be configured as follows, namely: comprising a square block 301 protruding from the side of the housing 1, a receiving cavity 303 is provided in the square block 301, the upper surface of the receiving cavity 303 is hollowed out, one end of the receiving cavity 303 is open, a colorimetric card 302 is placed in the receiving cavity 303, and the colorimetric card 302 can be drawn out of the receiving cavity 303 for easy replacement.

[0036] Preferably, in order to improve the anti-corrosion effect, the housing 1 and the square block 301 of the colorimetric area 3 are both made of plastic.

[0037] It should be noted that the Dongdu detection device of this application is used vertically during detection, and the detection process is specifically as follows:

[0038] Close the manual switch valve 405 on the connecting tube 402, open the manual switch valve 405 on the straw 404, hold the entire concentration detection device vertically with one hand, and use the other hand to pinch the rubber ball 403 to absorb liquid, then close the manual switch valve 405 on the straw 404, open the manual switch valve 405 on the connecting tube 402, and pinch the rubber ball 403 again to discharge the liquid into the liquid storage tank 401, and then insert the test paper 6 into the channel 5 until the end of the test paper 6 extends into the liquid in the liquid storage tank 401 for a moment, and then pull up the test paper 6 to separate the bottom of the test paper from the liquid, and then compare the color of the test paper 6 with the colorimetric area 3 to detect the concentration of the disinfectant.

[0039] After the detection is completed, the manual switch valve 405 on the connecting pipe 402 is opened, and the liquid in the liquid storage tank 401 flows back into the rubber ball 403, and then the manual switch valve 405 on the connecting pipe 402 is closed, and the manual switch valve 405 on the straw 404 is opened to discharge the liquid.

[0040] Of course, in order to facilitate comparison, the liquid can be discharged first and then the comparison can be performed.

[0041] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0042] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
