DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0046] The embodiment of the present application provides a test paper assembly 6, such as Figure 1-Figure 6 As shown, it includes: a loading body 61, a reaction sheet body 62 and a diaphragm layer 63;

[0047] The loading body 61 is provided with a reaction groove 617 and a drip groove 612 connected to the reaction groove 617 . The reaction sheet 62 is installed in the reaction groove 617 . The diaphragm layer 63 is fixed on the loading body 61 and covers the reaction groove 617 and the drip groove 612 .

[0048] When the test paper assembly 6 provided in the embodiment of the present application is tested, the diaphragm layer 63 covering the drip groove 612 is first punctured, and then a test liquid, such as urine, is dripped into the drip groove 612. The dripped test liquid flows from the drip groove 612 into the reaction groove 617, so that the test liquid contacts the reaction sheet 612 to produce a reaction, and then the test result of the test liquid is obtained according to the reaction information between the test liquid and the reaction sheet 612. The embodiment of the present application protects the reaction sheet 62 through the diaphragm layer 63, which can reduce the influence of environmental factors on the performance of the reaction sheet 62, improve the resistance of the reaction sheet 62 to interfering substances, thereby facilitating the improvement of the sensitivity and accuracy of the test results, and can extend the shelf life of the reaction sheet 62.

[0049] In one embodiment, in order to allow the liquid flowing from the drip groove 612 into the reaction groove 617 to flow along the reaction groove 617 so that the detection liquid can contact various parts of the reaction sheet 62, the loading body 61 is further provided with an exhaust groove 614 connected to the reaction groove 617, and the diaphragm layer 63 covers the exhaust groove 614. When the test paper assembly is used to detect the detection liquid, the diaphragm layer 63 covering the exhaust groove 614 is punctured, so that the reaction groove 617 can be vented through the exhaust groove 614, so that the detection liquid in the reaction groove 617 can flow smoothly to contact the reaction sheet 62, solving the problem that the liquid cannot flow due to gas blocking.

[0050] In one embodiment, the reaction tank 617 has an inlet 6171 connected to the drip tank 612 and an outlet 6172 connected to the exhaust tank 614, and the inlet 6171 and the outlet 6172 are respectively arranged at two ends of the reaction tank 617. In this way, due to the exhaust of the exhaust tank 614 far away from the inlet 614, the detection liquid flowing into the reaction tank 617 from the inlet 6171 will flow toward the exhaust tank 614, so that the detection liquid flows from the end with the inlet 6171 to the end with the outlet 6172, so that the detection liquid can spread to all parts of the reaction sheet body 62.

[0051] like Figure 3 and Figure 4 In the example shown, the drip groove 612 and the exhaust groove 614 are both located at the same end of the reaction groove 617, so that the drip groove 612 and the exhaust groove 614 can be punctured at the same end using a puncturing device. The inlet 6171 is located at the end of the reaction groove 617 away from the drip groove 612, and a main channel 613 is provided between the inlet 6171 and the drip groove 612, and the outlet 6172 is located at the end of the reaction groove 617 close to the drip groove 612.

[0052] In one embodiment, a limiting structure for limiting the reaction sheet 62 and an internal flow channel for flowing the detection liquid are provided in the reaction tank 617. The internal flow channel can facilitate guiding the fluid to flow in a predetermined direction so that the detection liquid can fully contact the reaction sheet 62.

[0053] like Figure 3-Figure 5 In the example shown, the limiting structure includes at least one end limiting block 616, and the end limiting block 616 is located at one end of the reaction sheet 62 close to the inlet 6171 to limit the end of the reaction sheet 62; the internal flow channel includes an end flow channel 6173 formed on the side of the end limiting block 616 away from the reaction sheet 62 and connected to the inlet 6171, and the at least one end limiting block 616 is formed with a plurality of first connecting ports 6175, and the detection liquid in the end flow channel 6173 flows to the reaction sheet 62 through the plurality of first connecting ports 6175. By providing the end limit block 616 and the end flow channel 6173, while the reaction sheet is limited by the end limit block 616, the fluid entering the inlet 6171 flows along the end flow channel 6173, and then flows to the reaction sheet 62 from the plurality of first connecting ports 6175. In this way, the fluid can flow over the entire end of the reaction sheet 62 in the width direction of the reaction sheet 62, and then flow from the end to the other end of the reaction sheet 62, so that the detection liquid can flow to every part of the reaction sheet 62.

[0054] In one example, the limiting structure also includes a plurality of intermediate limiting blocks 615 located in the middle of the reaction tank 617, and the plurality of intermediate limiting blocks 615 are arranged in two rows. The internal flow channel also includes an intermediate flow channel 6174 formed between the two rows of the intermediate limiting blocks 615 and connected to the end flow channel 6173. The intermediate flow channel 6174 extends from one end of the reaction tank 617 having the end limiting block 616 to the other end.

[0055] There are two reaction sheets 62, which are respectively installed in the areas on both sides of the multiple intermediate limit blocks 615; wherein each row of intermediate limit blocks 615 is formed with multiple second connecting ports 6176, and the detection liquid in the intermediate flow channel 6174 flows to the reaction sheets 6176 on both sides through the second connecting ports 676.

[0056] In one example, three first connecting ports 6175 are provided, the first connecting port 6175 located in the middle corresponds to the middle flow channel 6174, and the first connecting ports 6175 located on both sides respectively correspond to the side of the two reaction pieces 62 away from the middle flow channel 6174; three outlets 6172 are provided, and the three outlets 6172 respectively correspond to the middle flow channel 6174 and the side of the two reaction pieces 62 away from the middle flow channel 6174.

[0057] Figure 6 The flow state of the liquid after dripping from the drip groove 612 is shown, combined with Figure 3 and Figure 4 The detection liquid dripped from the drip groove 612 flows along the main channel 613 and enters the end channel 6173 of the reaction groove 617 from the inlet 6171. The liquid in the end channel 6173 flows to the reaction piece 61 from the three first connecting ports 6175 respectively, wherein a part of the liquid flows to the middle channel 6174 through the middle first connecting port 6175. The liquid in the middle channel 6174 flows toward the corresponding outlet 6172 and dispersedly flows to the reaction pieces 62 on both sides through the plurality of second connecting ports 6176. The other liquid flows toward the side of the reaction piece 62 away from the middle channel 6174 through the first connecting ports 6175 on both sides, thereby forming two side channels on both sides of the two reaction pieces 62 away from the middle channel. The two side channels flow toward the corresponding outlets 6172 while the detection liquid permeates into the reaction piece 62. The excess liquid drops will accumulate in the exhaust groove 614 and the drip groove 612.

[0058] In one embodiment, the reaction sheet 62 is provided with a plurality of area blocks, each area block having a different reaction indicator for detecting different indicators. For example, when the reaction sheet 62 detects urine, it is advantageous for the plurality of area blocks to detect different components of urine respectively, for example, the plurality of area blocks are respectively used to detect pH value, specific gravity, white blood cells, glucose, etc. in urine.

[0059] The test paper assembly may further include a desiccant 64, and a desiccant slot 618 may be provided on the loading body 61, and the desiccant 64 is placed in the desiccant slot 618. The desiccant 64 keeps the test paper assembly 6 dry, prevents the reaction sheet 62 from being damp and reducing the detection accuracy, and helps to increase the shelf life of the test paper assembly 6.

[0082] At least one detector is disposed in the chamber 711 (refer to Fig.13 ) is used to detect the reaction information of the test paper assembly 6 after contacting the detection liquid.

[0083] After the pushing device 4 pushes the test paper assembly 6 from the entrance 712 into the chamber 711 of the detection chamber 71, the detection liquid is dripped from the dripping port 713 to the test paper assembly 6, so that after the test paper assembly 6 reacts with the detection liquid, the detector in the chamber 711 can detect the reaction information of the test paper assembly 6, thereby obtaining the detection result. It is simple and convenient to use the drop detection device 7 to detect the detection liquid (such as urine), which reduces the difficulty of use for users and is conducive to improving detection efficiency. Moreover, the test paper assembly 6 and the detector are integrated in the chamber 711 of the detection chamber 71 for detection, which can reduce pollution and help improve the stability and accuracy of the detection.

[0084] When the test paper assembly 6 is installed on the drum 11, the side with the diaphragm layer 63 faces radially inward, and the pushing device 4 is configured to push the test paper assembly 6 located at the bottom of the drum 11 into the chamber 711, so as to push the side of the test paper assembly 6 with the diaphragm layer 63 in the chamber 711 upward. In this way, the diaphragm layer 63 can be punctured and liquid can be dripped on the upward side of the test paper assembly 6. When the test paper assembly 6 moves into the chamber 711 of the detection chamber 71, the exhaust groove 614 and the dripping groove 612 both correspond to the dripping port 713 of the detection chamber 71, so that the dripping groove 612 and the exhaust groove 614 can be punctured and liquid can be dripped from the dripping port 713.

[0085] The drop detection device 7 further includes a puncture drop assembly 72 , which is configured to puncture the diaphragm layer 63 on the test paper assembly 6 from the drop opening 713 and then drop liquid, so that the detection liquid contacts the reaction sheet 62 .

[0086] like Fig.18 As shown, the puncture and drip assembly 72 includes a lifting frame 723, a drip tube 724 installed on the lifting frame 723, and a lifting mechanism for driving the lifting frame 723 to move up and down. When the lifting frame 723 descends to a predetermined height position, the drip tube 724 punctures the diaphragm layer 63 of the test paper assembly 6 corresponding to the drip groove 612 and drips liquid into the drip groove 612.

[0087] The puncture and drip assembly 72 also includes a puncture and exhaust component 725 installed on the lifting frame 723. The puncture and exhaust component 725 is configured to puncture the diaphragm layer 63 of the test paper assembly 6 corresponding to the exhaust groove 614 when the lifting frame 723 descends to a predetermined height position to exhaust the exhaust groove 614.

[0088] The lifting mechanism may include a lifting motor 721 and a cam 722 driven to rotate by the lifting motor 721. When the cam 722 rotates to a position where the protrusion is downward, it pushes the lifting frame 723 down to the predetermined height position. The lifting mechanism also includes a return spring (not shown in the figure). When the protrusion of the cam 722 rotates upward, the return spring bounces the lifting frame 723 upward to the initial position.

[0089] The puncture and drip assembly 72 further includes a mounting bracket 727 fixed relative to the detection chamber 71, the lifting motor 721 is mounted on the mounting bracket 727, and the lifting frame 723 is slidably mounted on the mounting bracket 727. The mounting bracket 727 can be mounted on the support frame 23 of the installation body 2, such as Fig.11 and Fig.12 shown.

[0090] In addition, the puncture drip assembly 72 may further include a waste liquid discharge component 726 installed at the drip port 713 , and the excess test liquid dripped by the drip mechanism to the test paper assembly 6 flows into the waste liquid discharge component 726 .

[0091] In one embodiment, a light source is provided in the chamber 711 to provide light for the detection of the detector. The reaction sheet 62 of the test paper assembly 6 includes a plurality of area blocks, and a plurality of detectors may be provided in the detection chamber 71, each detector corresponding to detecting an area block, so that each detector can detect (for example, in urine) a component or index.

[0092] The following describes a process of testing urine using the test paper assembly provided in the present application according to a specific embodiment.

[0093] First, the test paper storage 1 installed with a plurality of test paper assemblies 6 is placed into the box structure 21 of the installation body 2 , and the roller 21 of the test paper storage 1 is installed on the rotating shaft 32 in the box structure 21 .

[0094] Start the test. After the roller 11 is installed in place, the controller controls the drive motor 31 to run, and the drive motor 31 drives the rotating shaft 32 to drive the roller 11 to rotate. After the roller 11 rotates a predetermined angle, the controller controls the drive motor 31 to stop, so that the roller 11 stops rotating. At this time, one of the test paper assemblies 6 at the bottom of the roller 11 is aligned with the bottom opening 1212 below, and the pushing groove 611 of the test paper assembly 6 is rotated to cooperate with the pushing claw 44 of the pushing device 4, and the pushing motor 41 drives the screw 42 to rotate, and the movable frame 43 moves from the first position to the second position, thereby pushing the test paper assembly 6 from the roller 11 to the detection chamber 71.

[0095] The lifting motor 721 drives the cam 722 to rotate, and the cam 722 pushes the lifting frame 723 to descend to a predetermined height position, at which the dropper 724 on the lifting frame 723 pierces the diaphragm layer 63 of the test paper assembly 6 corresponding to the drip groove 612, and drips urine into the drip groove 612, and the piercing exhaust component 725 on the lifting frame 723 pierces the diaphragm layer 63 corresponding to the exhaust groove 614. The dropper 724 can be connected to a urine collection device, and urine is provided to the dropper 724 through the urine collection device.

[0096] After the urine contacts the reaction sheet 62 of the test paper assembly 6, the detector in the detection chamber 71 detects the reaction information of the test paper assembly 6 and sends the detection information to the processor, which processes the data and obtains the detection result, and then sends the detection result to the display end.

[0097] After the test paper assembly 6 is tested, the push motor 41 drives the lead screw 42 to rotate in the opposite direction, and the moving frame 43 returns from the second position to the first position, pushing the used test paper assembly 6 back to the drum 11.

[0098] After the multiple test paper assemblies 6 on the drum 11 have been used up, the test paper storage 1 can be taken out and a new test paper storage 1 can be installed on the installation body 2 .
