Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a drug liquid detection device and a rapid drug liquid detection method. Background Technology
[0002] Since the advent of intravenous infusion therapy in humans, the method of drug mixing and preparation has remained fundamentally unchanged. The drugs are dissolved in a solvent and then added to the basic infusion, such as glucose injection, sodium chloride injection, or glucose sodium chloride injection, with the addition of therapeutic drugs to obtain a complete drug-containing infusion.
[0003] Existing technologies have developed intelligent robotic dispensing systems that can automate drug dispensing, which have been experimentally applied in clinical settings, significantly reducing the workload and improving the accuracy of clinical drug dispensing.
[0004] However, the problems solved by existing automated drug dispensing technology are still limited to replacing human hands with machines to perform repetitive tasks. It does not provide further upgrades to the drug dispensing process, but only addresses the scope of improving work efficiency and reducing labor intensity. Furthermore, the dispensed drugs still need to be manually inspected to ensure they are up to standard, so the degree of automation remains limited.
[0005] Therefore, a drug solution testing scheme needs to be proposed to further improve the efficiency of drug preparation. Summary of the Invention
[0006] In order to overcome at least one of the defects described in the prior art, the present invention provides a liquid medicine detection device to optimize the inconvenience of existing liquid medicine detection and improve the efficiency of dispensing medicine.
[0007] Another objective of this invention is to provide a rapid detection method for liquid medicine, thereby addressing the inconvenience of existing liquid medicine detection methods and improving the efficiency of medicine preparation.
[0008] The technical solution adopted by this invention to solve its problem is:
[0009] According to one aspect of the present invention, a drug solution detection device is provided, comprising a detection kit, the detection kit including a sampling needle and a detection box; wherein, the sampling needle is provided with an infusion channel, the infusion channel being connected to the detection box, the detection box being provided with a detection colorimetric card, which is capable of reacting with the drug solution to be detected to produce color, and the detection box being provided with a transparent observation window corresponding to the detection colorimetric card.
[0010] Therefore, the sampling needle of the test kit can be inserted into the container containing the drug solution to be tested to sample the drug solution. The sampled drug solution is delivered to the test box through the infusion channel in the sampling needle and reacts with the colorimetric card in the sampling box, causing the colorimetric card to change color and develop color. Through the transparent observation window, the relevant parameters of the drug solution can be observed intuitively, thereby improving the efficiency of drug solution testing and thus improving the efficiency of drug preparation.
[0011] Furthermore, a one-way valve structure is also provided between the liquid collection needle and the detection box.
[0012] Therefore, during the liquid collection process, the one-way valve structure allows the liquid obtained by the liquid-deficient needle to be transported unidirectionally to the detection box. After the detection box is filled with sufficient liquid, the one-way valve structure can prevent backflow, thus avoiding backflow of the liquid in the detection box and contamination of the container containing the liquid to be tested.
[0013] Furthermore, the one-way valve structure includes a valve seat with a cavity and a floating stop plate movably disposed in the cavity. The upper and lower sides of the valve seat are respectively provided with an inlet channel communicating with the liquid sampling needle and an outlet channel communicating with the detection box. Both the inlet channel and the outlet channel are connected to the cavity. The floating stop plate can float and seal the inlet channel when the cavity is filled with liquid.
[0014] Therefore, when the drug solution is sampled, the sampling needle is inserted into the container containing the drug solution to be tested. The drug solution is delivered into the infusion channel in the sampling needle, enters the one-way valve structure, and is delivered from the inlet channel to the outlet channel to the detection box. When the detection box is full of drug solution, the cavity of the valve seat is filled with drug solution, causing the floating stop plate to float up to close the inlet channel, thereby closing the one-way valve structure and preventing the drug solution from flowing back from the outlet channel to the inlet channel.
[0015] Furthermore, the valve seat includes a first valve body and a second valve body connected to the first valve body. The inlet channel and the outlet channel are respectively disposed in the first valve body and the second valve body. The first valve body is used to connect with the liquid collection needle, and the second valve body is used to connect with the detection box.
[0016] Therefore, the valve seat is designed as a split unit, formed by connecting the first valve body and the second valve body, which reduces the difficulty of processing and the manufacturing cost.
[0017] Furthermore, a boss protruding into the cavity is provided on one side of the liquid outlet channel inside the valve seat. The liquid outlet channel is provided through the boss. The top edge of the boss and the top wall of the valve seat maintain a gap to accommodate the floating stopper, and the boss can support the floating stopper.
[0018] Therefore, a gap is maintained between the boss and the top wall of the valve seat to accommodate the floating stopper. The boss shortens the distance the floating stopper needs to float upwards to close the inlet channel, enabling the one-way valve structure to close quickly and achieve a backstop function.
[0019] Furthermore, the boss is provided with several liquid passage holes in the circumference, and the liquid passage holes are connected to the liquid outlet channel.
[0020] Therefore, during the process of conveying liquid from the inlet channel to the outlet channel, the setting of the liquid passage hole increases the liquid outlet path of the outlet channel, avoiding the phenomenon that the one-way valve structure has difficulty discharging liquid due to the floating stop plate sealing the inlet at the end of the boss under the action of gravity.
[0021] Furthermore, the one-way valve structure includes a valve seat with a cavity and an elastic diaphragm disposed within the cavity. On opposite sides of the valve seat, there are liquid inlet channels communicating with the liquid sampling needle and liquid outlet channels communicating with the detection box, respectively. Both the liquid inlet channels and the liquid outlet channels are connected to the cavity. The elastic diaphragm is fixed circumferentially to the valve seat, and a one-way opening and closing groove is opened in the center of the elastic diaphragm. A push pin is disposed on the side of the valve seat near the liquid inlet channel, and the push pin extends toward the liquid outlet channel and pushes into the one-way opening and closing groove.
[0022] Therefore, when the elastic diaphragm is under positive pressure from the liquid on the side of the ejector pin, the liquid exerts pressure on the elastic diaphragm, causing it to detach from the ejector pin and open the one-way opening and closing groove, thus allowing the liquid on the inlet channel side to flow to the outlet channel side. When the elastic diaphragm is under negative pressure from the liquid on the side away from the ejector pin, the elastic diaphragm is compressed and adheres to the ejector pin surface, causing the one-way opening and closing groove to close and prevent the liquid on the outlet channel side of the elastic diaphragm from flowing to the inlet channel side.
[0023] Furthermore, the liquid outlet channel is arranged vertically in the valve seat in an upward and downward direction, or horizontally in the valve seat in a left and right direction, or the liquid outlet channel is arranged at an angle to the horizontal direction in the valve seat.
[0024] Furthermore, the unidirectional opening and closing groove includes a first strip groove, which is arranged through the thickness direction of the elastic diaphragm.
[0025] Thus, the first groove is designed to allow the liquid medicine to pass through, and the elastic diaphragm can close when subjected to reverse flow liquid pressure to achieve reverse backflow prevention.
[0026] Furthermore, the unidirectional opening and closing groove also includes a second strip groove, which is a blind groove and is located on the side facing the pin. The second strip groove intersects with the first strip groove.
[0027] Therefore, since the second groove is a blind groove and is located on the side of the elastic diaphragm facing the ejector pin, when liquid enters the side of the elastic diaphragm facing the ejector pin, the liquid can enter the first groove and the second groove respectively. The opening of the second groove makes the first groove easier to expand under the action of liquid pressure. When the liquid flows in the opposite direction from the back of the elastic diaphragm, since there is only the first groove as a through groove, the liquid is not easy to pass through the elastic diaphragm, which makes it easier to close the first groove. Thus, the setting of the second groove makes it easier for the elastic diaphragm facing the ejector pin to deform to the other side, expand and open the first groove. The function of the second groove is equivalent to an indicator of the one-way opening direction.
[0028] Furthermore, the second strip groove is orthogonal to the first strip groove.
[0029] This makes the second groove orthogonal to the first groove, resulting in the best unidirectional expansion effect of the elastic diaphragm.
[0030] Furthermore, several protrusions are provided on one side of the valve seat near the liquid inlet channel, which creates a flow gap between the inner wall of the valve seat and the elastic diaphragm.
[0031] Therefore, the protrusion allows the elastic diaphragm to maintain a flow gap with the inner wall of the valve seat, avoiding the elastic diaphragm from sticking to the inner wall of the valve seat and generating large liquid inlet resistance, or even causing the liquid to be unable to pass through the one-way valve structure.
[0032] Furthermore, multiple protrusions are evenly distributed around the center of the fluid passage.
[0033] This allows for the creation of flow gaps from multiple directions, further reducing inlet resistance.
[0034] Furthermore, the valve seat includes a first valve body and a second valve body connected to the first valve body. The inlet channel and the outlet channel are respectively disposed in the first valve body and the second valve body. The first valve body is used to connect with the liquid collection needle, and the second valve body is used to connect with the detection box.
[0035] Therefore, the valve seat is designed as a split unit, formed by connecting the first valve body and the second valve body, which reduces the difficulty of processing and the manufacturing cost.
[0036] Furthermore, the inner side of the second valve body is provided with several pressing protrusions, which extend toward one side of the first valve body and press against the edge of the elastic diaphragm, so that the edge of the elastic diaphragm is fixed to the first valve body and the second valve body.
[0037] Therefore, the setting of the pressure protrusion can press the elastic diaphragm against one side of the first valve body, so that the edge of the elastic diaphragm is fixed relative to the first valve body and the second valve body, simplifying the structure and facilitating installation.
[0038] Furthermore, multiple pressure protrusions are evenly distributed around the center of the liquid outlet channel.
[0039] Therefore, the multiple pressure protrusions provide sufficient fastening force for fixing the elastic diaphragm, making the fixing of the elastic diaphragm stable and reliable.
[0040] Furthermore, at least one quantitative sampling chamber is provided inside the detection box. The quantitative sampling chamber is connected to the liquid sampling needle. The observation window is set corresponding to the quantitative sampling chamber. The detection colorimetric card is set inside the quantitative sampling chamber and located at the observation window.
[0041] Therefore, the quantitative sampling chamber is designed to match the volume of the drug solution reacting with the colorimetric card, which helps to ensure the consistency of the test results and reduce testing errors.
[0042] Furthermore, two or more quantitative sampling chambers are set up.
[0043] Therefore, setting up at least two quantitative sampling chambers allows for the comparison of multiple sample solutions, which helps improve the precision and accuracy of the detection.
[0044] Furthermore, the test box is also equipped with a vent, which is connected to the quantitative sampling chamber and is sealed by a breathable and waterproof membrane.
[0045] Therefore, the breathable and waterproof membrane allows air to pass through the inside and outside of the test box, which facilitates the filling of the quantitative sampling chamber with the drug solution, ensuring sufficient drug solution to react with the colorimetric card. The breathable and waterproof membrane also prevents the drug solution in the quantitative sampling chamber from overflowing to the outside of the test box or prevents water vapor from the outside of the test box from entering the quantitative sampling chamber and causing contamination of the quantitative sampling chamber.
[0046] Furthermore, the drug solution detection device also includes a base body, on which a liquid sampling port is provided for placing a container containing the drug solution to be tested. The test kit is assembled on the base body, and the liquid sampling needle extends into the liquid sampling port.
[0047] Therefore, the sampling port is used to place the container containing the drug solution to be tested, and the sampling needle is inserted into the container to sample the drug solution to be tested. Sampling and testing are convenient, reducing the difficulty of drug solution testing.
[0048] Furthermore, the drug liquid detection device also includes a camera component, a controller, and a display component mounted on the base body. The camera component is set with an observation window and is used to acquire images of the color-developed detection color card and transmit them to the controller. The controller compares the images with pre-stored image data to output the corresponding detection results to the display component. The display component receives the detection results and displays them.
[0049] Therefore, the camera component can acquire images of the color-developed detection card and transmit them to the controller. The controller compares the acquired images with the pre-stored image data to output the corresponding detection results to the display component. The display component receives the detection results and displays them. Thus, when testing a liquid medicine, after inserting the medicine bag containing the liquid to be tested into the dispensing port, the detection results of the liquid medicine can be directly viewed on the display component. This is convenient, fast, reduces the deviation of visual identification, and improves the degree of automation.
[0050] According to another aspect of the present invention, the present invention provides a rapid detection method for pharmaceutical solutions, employing any of the above-described pharmaceutical solution detection devices, comprising the following steps:
[0051] Step S1: Insert the liquid sampling needle of the liquid detection device into the container containing the liquid to be tested, obtain the liquid to be tested, and transfer it to the detection box of the liquid detection device;
[0052] Step S2: The colorimetric card in the detection box reacts with the drug solution to be tested and develops color.
[0053] This improves the convenience and efficiency of drug solution testing, thereby increasing the efficiency of solution preparation.
[0054] Furthermore, it also includes step S3: the camera component of the drug liquid detection device acquires an image of the color-developed detection card and transmits it to the controller. The controller compares the image with the pre-stored image data and outputs the corresponding detection result to the display component. The display component receives the detection result and displays it.
[0055] Therefore, the test results of the medicine solution can be viewed directly on the display component, reducing the deviation of visual identification, further improving the convenience of medicine solution testing, improving the efficiency of medicine solution testing, and thus improving the efficiency of solution preparation.
[0056] Furthermore, it also includes step S4: the controller compares the detection result with the pre-stored standard parameter data and outputs a suggested data value to the display component, and the display component receives the suggested data value and displays it.
[0057] Therefore, the display component can also display suggestions after the controller compares the standard parameter data values, which makes it easier for testing personnel or dispensing personnel to adjust the dispensing of the medicine and further improve the efficiency of dispensing.
[0058] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:
[0059] 1) Provide a drug liquid detection device to improve the efficiency of drug liquid detection, thereby improving the efficiency of drug preparation;
[0060] 2) A one-way valve structure is installed between the liquid sampling needle and the detection box of the liquid detection device to prevent the liquid in the detection box from flowing back to the sampling port and contaminating the medicine bag containing the liquid to be tested in the sampling port.
[0061] 3) Provide a rapid detection method for drug solutions, improve the convenience and efficiency of drug solution detection, and thus improve the efficiency of solution preparation. Attached Figure Description

Detailed Implementation
[0075] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0076] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0078] Example 1
[0079] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 This invention discloses a drug solution detection device, including a detection kit 1. The detection kit 1 includes a liquid collection needle 101 and a detection box 102. The liquid collection needle 101 is provided with an infusion channel 1011, which is connected to the detection box 102. The detection box 102 is provided with a detection colorimetric card 103, which can react with the drug solution to be tested and develop color. A transparent observation window 1021 is provided on the detection box 102 corresponding to the detection colorimetric card 103.
[0080] Therefore, the sampling needle 101 of the test kit 1 can be inserted into the container containing the drug solution to be tested to sample the drug solution. The sampled drug solution is delivered to the test box 102 through the infusion channel 1011 in the sampling needle 101 and reacts with the detection color card 103 in the sampling box, causing the detection color card 103 to change color and develop color. Through the transparent observation window 1021, the detection of relevant parameters of the drug solution can be observed intuitively, thereby improving the efficiency of drug solution detection and thus improving the efficiency of drug preparation.
[0081] The container holding the solution to be tested is a standard medicine bottle or medicine bag.
[0082] This drug solution detection device is used to detect parameters of the drug solution, including but not limited to the pH and osmotic pressure of the drug solution.
[0083] For example, if the test item is the acidity or alkalinity of the drug solution, pH test paper can be used to test the colorimetric card 103.
[0084] The end of the sampling needle 101 is set as a sharp point, so that the sampling needle 101 can smoothly penetrate into the container containing the drug solution to be tested for drug sampling.
[0085] refer to Figure 4 , Figure 7 Furthermore, a one-way valve structure 2 is also provided between the liquid collection needle 101 and the detection box 102.
[0086] Therefore, during the liquid collection process of the liquid collection needle 101, the one-way valve structure 2 enables the liquid obtained by the liquid-deficient needle to be transported unidirectionally to the detection box 102. After the detection box 102 is filled with sufficient liquid, the one-way valve structure 2 can generate a backflow prevention function. In the figure, G indicates the direction of liquid flow, which prevents the liquid in the detection box 102 from flowing back and contaminating the container containing the liquid to be tested.
[0087] Furthermore, at least one quantitative sampling chamber 1022 is provided inside the detection box 102. The quantitative sampling chamber 1022 is connected to the liquid sampling needle 101. The observation window 1021 is set corresponding to the quantitative sampling chamber 1022. The detection colorimetric card 103 is set inside the quantitative sampling chamber 1022 and located at the observation window 1021.
[0088] Therefore, the quantitative sampling chamber 1022 ensures that the volume of the drug solution reacting with the colorimetric card 103 in different detection boxes 102 is consistent, which helps to ensure the consistency of the detection results and reduce the inspection error.
[0089] Furthermore, two or more quantitative sampling chambers 1022 are provided, and all quantitative sampling chambers 1022 are connected to the infusion channel 1011 of the sampling needle 101; thus, by providing at least two quantitative sampling chambers 1022, it is possible to compare multiple sampled drug solutions, which is beneficial to improving the accuracy and precision of the detection.
[0090] Furthermore, the detection box 102 is also provided with a vent 1023, which is connected to the quantitative sampling chamber 1022, and the vent 1023 is sealed by a breathable and waterproof membrane 10231.
[0091] Therefore, the breathable and waterproof membrane 10231 allows ventilation between the inside and outside of the detection box 102, which facilitates the filling of the quantitative sampling chamber 1022 with the drug solution, ensuring sufficient drug solution to react with the detection colorimetric card 103. The breathable and waterproof membrane 10231 also prevents the drug solution in the quantitative sampling chamber 1022 from overflowing out of the detection box 102 or prevents water vapor outside the detection box 102 from entering the quantitative sampling chamber 1022 and causing contamination of the quantitative sampling chamber 1022.
[0092] Furthermore, the drug solution detection device also includes a base body 3, on which a liquid extraction port 301 is provided for placing a container containing the drug solution to be tested. The test kit 1 is assembled on the base body 3, and the liquid extraction needle 101 extends into the liquid extraction port 301.
[0093] Therefore, the liquid sampling port 301 is used to place the container containing the liquid to be tested, and the liquid sampling needle 101 is inserted into the container to sample the liquid to be tested. Sampling and testing are convenient, reducing the difficulty of testing the liquid.
[0094] Furthermore, the drug liquid detection device also includes a camera component 4, a controller (not shown in the figure), and a display component 5, which are set on the base body 3. The camera component 4 is set in the observation window 1021 and is used to acquire images of the color-developed detection card 103 and transmit them to the controller. The controller compares the images with the pre-stored image data to output the corresponding detection results to the display component 5. The display component 5 receives the detection results and displays them.
[0095] Therefore, the camera component 4 can acquire images of the color-developed detection color card 103 and transmit them to the controller. The controller compares the images with the pre-stored image data to output the corresponding detection results to the display component 5. The display component 5 receives the detection results and displays them. Thus, when testing a liquid medicine, after inserting the medicine bag containing the liquid medicine to be tested into the liquid dispensing port 301, the detection results of the liquid medicine can be directly viewed on the display component 5. This is convenient, fast, reduces the deviation of visual identification, and improves the degree of automation.
[0096] Furthermore, the camera component 4 mainly includes a camera whose lens is positioned facing the transparent observation window 1021.
[0097] Display component 5 mainly includes a display screen, which is electrically connected to the controller.
[0098] The controller is mainly used for image processing and data comparison. It has pre-stored image data values corresponding to different parameter states, such as image data of test colorimetric cards under different pH values.
[0099] The process of displaying the test results is as follows: the camera component 4 takes a picture of the color-developed test color card 103, acquires the image, and transmits the image data to the controller. The controller receives the image data signal, compares it with the pre-stored image data, finds the parameter value that matches the acquired image, and after obtaining the parameter value, transmits the data to the display component 5, which then displays the test results.
[0100] Each observation window 1021 is equipped with a corresponding camera. The images acquired by different cameras are sent to the controller. The controller compares the acquired images with the pre-stored image data to obtain the corresponding detection values. Then, the average of all the detection values is taken to obtain the final more accurate detection result, which is displayed in the display component 5.
[0101] Furthermore, the controller can also store standard values of corresponding parameter data for the corresponding drug solution. The controller performs data calculations on the detection results and standard values to obtain a calculation result, and outputs a suggestion based on the calculation result. This output suggestion can be output to the display component 5, which displays the drug preparation suggestion for the drug solution. For example, if the pH value of the detected drug solution is 6, while the standard pH value of the drug solution is 7, the controller returns a calculation result that the pH is lower than the standard value, and outputs a suggestion to "increase the pH value of the drug solution". The drug preparation suggestion process for other parameters can also refer to the above process.
[0102] Furthermore, the controller can have a built-in or wirelessly networked database of drug incompatibilities and drug compatibility recommendations. After detecting the corresponding drug parameters, it will compare the parameters with the data in the "drug database".
[0103] If the drug detection parameters are within the maximum efficacy or recommended range, the controller will give a "use directly" recommendation.
[0104] If the drug test results deviate from the built-in data values in the "drug library", the recommended parameter range specified by the drug will be displayed on the display component 5. The recommended medication to be adjusted will be calculated by the difference between the drug library data and the actual test data, and clinical adjustment suggestions will be given to ensure that the drug indicators are within the optimal range for each intravenous infusion treatment.
[0105] Wireless networking can be achieved through Bluetooth, WIFI, or 3G, 4G, or 5G communication methods.
[0106] In this embodiment, the display component 5 includes a first display 501 and a second display 502, wherein the first display 501 is used to display the detection data results, and the second display 502 is used to display suggestions for dispensing and administering medication.
[0107] This allows for clearer and more precise acquisition of the relevant parameters and recommendations for the drug solution, making detection convenient and highly intelligent.
[0108] Furthermore, to improve the accuracy of recognition and reduce dependence on and interference from ambient light, a self-emissive LED supplementary light source (not shown in the figure) is used on the camera component 4, thereby shielding external interference light and improving the accuracy of image acquisition.
[0109] Furthermore, the detection window is made of high-transmittance, low-refractive-index materials such as plastic and quartz, and the other surfaces of the detection box 102 are designed to be non-transparent to ensure that external light does not enter the detection box 102 and to reduce the interference of the environment on the imaging results.
[0110] Example 2
[0111] See Figures 4-6 This embodiment discloses a one-way valve structure 2, which can be used in the test kit 1 in embodiment 1 to play the role of one-way flow of liquid.
[0112] In this embodiment, the one-way valve structure 2 includes a valve seat 201 with a cavity and a floating stop plate 202 movably disposed in the cavity. The upper and lower sides of the valve seat 201 are respectively provided with an inlet channel 203 communicating with the liquid needle 101 and an outlet channel 204 communicating with the detection box 102. Both the inlet channel 203 and the outlet channel 204 are communicating with the cavity. The floating stop plate 202 can float and seal the inlet channel 203 when the cavity is filled with liquid.
[0113] Therefore, when the medicine is sampled, the sampling needle 101 is inserted into the container containing the medicine to be tested. The medicine is delivered to the infusion channel 1011 in the sampling needle 101, enters the one-way valve structure 2, and is delivered to the detection box 102 from the inlet channel 203 to the outlet channel 204. When the detection box 102 is full of medicine, the cavity of the valve seat 201 is filled with medicine, causing the floating stop plate 202 to float up to close the inlet channel 203, thereby closing the one-way valve structure 2 and preventing the medicine from flowing back from the outlet channel 204 to the inlet channel 203.
[0114] Furthermore, the valve seat 201 includes a first valve body 2011 and a second valve body 2012 connected to the first valve body 2011. The liquid inlet channel 203 and the liquid outlet channel 204 are respectively disposed in the first valve body 2011 and the second valve body 2012. The first valve body 2011 is used to connect with the liquid collection needle 101, and the second valve body 2012 is used to connect with the detection box 102.
[0115] Therefore, the valve seat 201 is designed as a split unit, which is formed by connecting the first valve body 2011 and the second valve body 2012, thereby reducing the processing difficulty and manufacturing cost.
[0116] The first valve body 2011 and the second valve body 2012 can be connected by welding, bonding or snap-fit connection.
[0117] Furthermore, a boss portion 205 protruding into the cavity is provided on one side of the liquid outlet channel 204 inside the valve seat 201. The liquid outlet channel 204 is provided through the boss portion 205. The top edge of the boss portion 205 and the top wall of the valve seat 201 maintain a gap to accommodate the floating stopper 202, and the boss portion 205 can support the floating stopper 202.
[0118] Therefore, a gap is maintained between the boss 205 and the top wall of the valve seat 201 to accommodate the floating stopper 202. The setting of the boss 205 shortens the floating stopper 202's required upward floating distance during the process of floating and closing the liquid inlet channel 203, which enables the one-way valve structure 2 to close quickly and achieve a backstop function.
[0119] Furthermore, the boss portion 205 is provided with a plurality of liquid passage holes 2051 circumferentially, and the liquid passage holes 2051 are connected to the liquid outlet channel 204.
[0120] Therefore, during the process of liquid transfer from the inlet channel 203 to the outlet channel 204, the setting of the liquid passage hole 2051 increases the liquid outlet path of the outlet channel 204, avoiding the phenomenon that the one-way valve structure 2 has difficulty discharging liquid due to the floating stop plate 202 sealing the inlet at the end of the boss portion 205 under the action of gravity.
[0121] Example 3
[0122] See Figures 7-11 This embodiment discloses another one-way valve structure 2, which can be used in the test kit 1 in embodiment 1 to play the role of one-way flow of liquid.
[0123] In this embodiment, the one-way valve structure 2 includes a valve seat 201 with a cavity and an elastic diaphragm 206 disposed in the cavity. On opposite sides of the valve seat 201, there are liquid inlet channels 203 communicating with the liquid needle 101 and liquid outlet channels 204 communicating with the detection box 102, respectively. Both the liquid inlet channels 203 and the liquid outlet channels 204 are communicating with the cavity. The elastic diaphragm 206 is fixed to the valve seat 201 in the circumferential direction. A one-way opening and closing groove 2061 is opened in the center of the elastic diaphragm 206. A push needle part 207 is provided on the side of the valve seat 201 near the liquid inlet channel 203. The push needle part 207 extends towards the liquid outlet channel 204 and pushes into the one-way opening and closing groove 2061.
[0124] Therefore, when the elastic diaphragm 206 is under positive pressure from the liquid on the side of the ejector pin 207, the liquid exerts pressure on the elastic diaphragm 206, causing it to detach from the ejector pin 207 and open the one-way opening and closing groove 2061, thereby allowing the liquid on the side of the inlet channel 203 to flow to the side of the outlet channel 204. When the elastic diaphragm 206 is under negative pressure from the liquid on the side away from the ejector pin, the elastic diaphragm 206 is pressed and adheres to the surface of the ejector pin 207, causing the one-way opening and closing groove 2061 to close and prevent the liquid on the side of the elastic diaphragm 206 facing the outlet channel 204 from flowing to the side of the inlet channel 203.
[0125] Furthermore, the elastic diaphragm 206 can be made of rubber, silicone, or medical-grade elastic materials. It should be noted that the material of the elastic diaphragm 206 must not react chemically with the drug solution to avoid affecting the detection process.
[0126] Furthermore, the liquid outlet channel 204 is arranged vertically in the valve seat 201 in an up-down direction, or horizontally in the valve seat 201 in a left-right direction, or the liquid outlet channel 204 is arranged at an angle to the horizontal direction in the valve seat 201.
[0127] Furthermore, the unidirectional opening and closing groove 2061 includes a first strip groove 20611, which is arranged through the thickness direction of the elastic diaphragm 206.
[0128] Thus, the first groove 20611 is provided for the liquid to pass through, and can be closed when the elastic diaphragm 206 is subjected to reverse backflow liquid pressure to achieve reverse backflow prevention.
[0129] Furthermore, the one-way opening and closing groove 2061 also includes a second strip groove 20612, which is a blind groove and is located on the side facing the pin portion 207. The second strip groove 20612 is intersecting with the first strip groove 20611.
[0130] Therefore, since the second strip groove 20612 is a blind groove and is located on the side of the elastic diaphragm 206 facing the ejector pin 207, when liquid enters the side of the elastic diaphragm 206 facing the ejector pin 207, the liquid can enter the first strip groove 20611 and the second strip groove 20612 respectively. The opening of the second strip groove 20612 makes it easier for the first strip groove 20611 to expand under the action of liquid pressure. When the liquid flows in the opposite direction from the back of the elastic diaphragm 206, since there is only the first strip groove 20611 as a through groove, the liquid does not easily pass through the elastic diaphragm 206, but makes it easier to close the first strip groove 20611. Thus, the setting of the second strip groove 20612 makes it easier for the elastic diaphragm 206 facing the ejector pin to deform to the other side, expand and open the first strip groove 20611. The function of the second strip groove 20612 is equivalent to an indicator of the one-way opening direction.
[0131] Furthermore, the second strip groove 20612 is orthogonally arranged to the first strip groove 20611.
[0132] This makes the second groove 20612 orthogonal to the first groove 20611, resulting in the best unidirectional expansion effect of the elastic diaphragm 206.
[0133] Furthermore, a number of protrusions 208 are provided on one side of the valve seat 201 near the liquid inlet channel 203. The protrusions 208 create a flow gap between the inner wall of the valve seat 201 and the elastic diaphragm 206 (not shown in the figure).
[0134] Therefore, the protrusion 208 enables the elastic diaphragm 206 to maintain a flow gap with the inner wall of the valve seat 201, avoiding the elastic diaphragm 206 from sticking to the inner wall of the valve seat 201 and generating a large liquid inlet resistance, or even causing the liquid to be unable to pass through the one-way valve structure 2.
[0135] Furthermore, multiple protrusions 208 are evenly distributed around the center of the liquid passage.
[0136] This allows for the creation of flow gaps from multiple directions, further reducing inlet resistance.
[0137] Furthermore, the valve seat 201 includes a first valve body 2011 and a second valve body 2012 connected to the first valve body 2011. The liquid inlet channel 203 and the liquid outlet channel 204 are respectively disposed in the first valve body 2011 and the second valve body 2012. The first valve body 2011 is used to connect with the liquid collection needle 101, and the second valve body 2012 is used to connect with the detection box 102.
[0138] Therefore, the valve seat 201 is designed as a split unit, which is formed by connecting the first valve body 2011 and the second valve body 2012, thereby reducing the processing difficulty and manufacturing cost.
[0139] Furthermore, the inner side of the second valve body 2012 is provided with a plurality of pressing protrusions 209. The pressing protrusions 209 extend toward one side of the first valve body 2011 and press against the edge of the elastic diaphragm 206, so that the edge of the elastic diaphragm 206 is fixed to the first valve body 2011 and the second valve body 2012.
[0140] Therefore, the setting of the pressing protrusion 209 can press the elastic diaphragm 206 against one side of the first valve body 2011, so that the edge of the elastic diaphragm 206 is fixed relative to the first valve body 2011 and the second valve body 2012, simplifying the structure and facilitating installation.
[0141] Furthermore, multiple pressure protrusions 209 are evenly distributed around the center of the liquid channel 204.
[0142] Therefore, the arrangement of multiple pressure protrusions 209 can provide sufficient fastening force for fixing the elastic diaphragm 206, making the fixing of the elastic diaphragm 206 stable and reliable.

[0148] This improves the convenience and efficiency of drug solution testing, thereby increasing the efficiency of solution preparation.
[0149] This testing process can be used to detect parameters of the drug solution, including but not limited to the pH and osmotic pressure of the solution.

The controller compares the acquired image with the pre-stored image data and outputs the corresponding detection result to the display component 5. The display component 5 receives the detection result and displays it.
[0151] Therefore, the controller processes the image acquired by the camera component 4 and compares it with the pre-stored data to output the detection results. The detection results of the medicine can be directly viewed on the display component 5, reducing the deviation of visual identification, further improving the convenience of medicine detection, improving the efficiency of medicine detection, and thus improving the efficiency of medicine preparation.
[0152] Furthermore, it also includes step S4: the controller compares the detection result with the pre-stored standard parameter data and outputs a suggested data value to the display component 5, and the display component 5 receives the suggested data value and displays it.
[0153] Furthermore, this suggested data value includes, but is not limited to, the communication data value converted from data suggestions on medication results and medication suggestions (dosage, contraindications, etc.).
[0154] Therefore, the display component 5 can also display suggestions after the controller compares the standard parameter data values, which makes it easier for testing personnel or dispensing personnel to adjust the dispensing of the medicine, further improve the efficiency of dispensing, and also help to realize intelligent medication use.
[0155] In summary, the drug solution detection device and rapid drug solution detection method provided by this invention improve the convenience and efficiency of drug solution detection, thereby improving the efficiency of solution preparation. It can also intelligently provide medication advice and contraindications for drug solutions.
