DETAILED DESCRIPTION
[0051] 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.
[0052] The embodiment of the present application provides a drop detection device, such as Figure 1-Figure 4 The drop detection device 7 shown comprises:
[0053] The detection chamber 71 has an entrance 712 and a chamber 711 connected to the entrance 712. The test paper assembly 6 for testing can slide into the chamber 711 from the entrance 712 and slide out of the chamber 711 from the entrance 712. The detection chamber 71 also has a dripping port 713, and the test liquid is dripped from the dripping port 713 to the test paper assembly 6 located in the chamber 711.
[0054] At least one detector is disposed in the chamber 711 and is used to detect the reaction information of the test paper assembly 6 after contacting the test liquid.
[0055] The drop detection device provided by the embodiment of the present application, after the test paper assembly to be tested is pushed into the chamber 711 of the detection chamber 71 from the entrance 712, 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, so as to obtain 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 the detection efficiency. Moreover, the test paper assembly 6 and the detector are integrated in the chamber of the detection chamber 71 for detection, which can reduce pollution and help improve the stability and accuracy of the detection.
[0056] Figure 20-Figure 25 A test paper assembly 6 provided in an embodiment is shown. The test paper assembly 6 includes a loading body 61 , a reaction layer 62 mounted on the loading body 61 , and a diaphragm layer 63 on a side of the reaction layer 62 facing away from the loading body 61 .
[0057] 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 layer 62 .
[0058] In one example, the loading body 61 of the test paper assembly 6 is provided with a mounting groove 617 for mounting the reaction layer 62 and a drip groove 612 connected to the mounting groove 617; the diaphragm layer 63 covers the mounting groove 617 and the drip groove 612, and the detection liquid dripped from the drip groove 612 can flow into the mounting groove 617 to achieve contact with the reaction layer 62. Therefore, to achieve dripping into the drip groove 612, it is necessary to puncture the diaphragm layer 62 above the drip groove 612. In addition, the loading body 61 can also be provided with an exhaust groove 614 connected to the mounting groove 617, and the diaphragm layer 63 covers the exhaust groove 614. Exhausting through the exhaust groove 614 can make the dripping liquid flow smoothly along the mounting groove 617, so that the detection liquid is fully in contact with the reaction layer 62. In order to exhaust the exhaust groove 614, it is also necessary to puncture the diaphragm layer 62 above the exhaust groove 614.
[0059] Among them, when the test paper assembly 6 moves into the chamber 711 of the detection chamber 71, the exhaust groove 614 and the drip groove 612 both correspond to the drip port 713 of the detection chamber 71, so that the drip groove 612 and the exhaust groove 614 are punctured and dripped from the drip port 713, and the drip groove 612 and the exhaust groove 614 can also be used to store excess detection liquid.
[0060] In addition, a desiccant slot 618 for placing a desiccant 64 may be provided on the loading body 61, and the desiccant 64 is used to keep the test paper assembly 6 dry to prevent moisture and the like from affecting the detection accuracy.
[0061] exist Figure 4 In the illustrated embodiment, 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 62 of the test paper assembly 6 corresponding to the drip groove 612 and drips liquid into the drip groove 612.
[0062] 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 62 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.
[0063] 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.
[0064] Among them, the puncture drip assembly 72 also includes a mounting bracket 727 fixed relatively to the detection chamber 71, the lifting motor 721 is installed on the mounting bracket 727, the lifting frame 723 is slidably installed on the mounting bracket 727, and the drip tube 724 and the puncture exhaust component 725 on the lifting frame 723 are installed corresponding to the drip port 713 of the detection chamber 71.
[0065] In addition, the puncture and drip assembly 72 may further include a waste liquid discharge component 726 installed at the drip port 71 , and the excess detection liquid dripped into the test paper assembly 6 by the puncture and drip assembly 72 flows into the waste liquid discharge component 726 .
[0066] In one embodiment, a light source is disposed in the chamber 711 to provide light for detection by the detector.
[0067] In one embodiment, at least one detector in the chamber 711 includes a color detector for acquiring the color of the test paper assembly 6, and the test liquid is analyzed through the color information acquired by the color detector.
[0068] When a test liquid, such as urine, is dropped onto the test paper assembly 6, the reaction layer 62 of the test paper assembly 6 comes into contact with the urine, and the chemical components of the reaction layer 62 react with the urine to cause a color change, the depth of the color being proportional to the concentration of the corresponding substance in the urine. Therefore, by detecting the color information of the test paper assembly 6, the composition of the urine can be detected.
[0069] Among them, Fig.21 As shown, the reaction layer 62 of the test paper assembly 6 may include a plurality of area blocks, each of which has a different reaction indicator for detecting different components of urine. For example, the plurality of area blocks are respectively used to detect pH value, specific gravity, leukocytes, glucose, etc. in urine. Accordingly, the detector is provided with a plurality of Fig.10 and Fig.11 As shown, a plurality of detectors 714 are arranged in the detection chamber 71, and each detector 714 corresponds to detecting an area block, thereby detecting a component or index in urine.
[0070] In order to position the reaction layer 62 in the mounting groove 617 so that the multiple area blocks can correspond to the multiple detectors one by one, a positioning block is provided on the carrier body 61. Figure 22-Figure 24As shown, a plurality of intermediate stop blocks 615 are provided in the middle of the installation groove 617, and two long reaction layers 62 can be respectively installed on both sides of the intermediate stop blocks 615. One end of the reaction layer 62 close to the drip groove 612 is limited by the end wall of the groove, and the other end is limited by an end stop block 616. In addition, in order to allow the detection liquid to fully contact with each area block, the drip groove 612 is connected with a flow channel 613, and the flow channel 613 extends to the end of the installation groove 617 away from the drip groove 612. The detection liquid dripped from the drip groove 612 first flows to the end of the installation groove 617 away from the drip groove 612. Since the exhaust groove 614 can exhaust, the detection liquid will flow toward the end close to the exhaust groove 614. In this way, the detection liquid is easy to fully contact with each area block. Fig.25 The diagram shows a flow state in which the detection liquid flows into the installation groove 617 along the flow channel 613 after the detection liquid is dripped into the drip groove 612 .
[0071] It is understandable that the detector is not limited to the use of a color detector. Depending on the type of test fluid to be detected or the indicator to be detected, at least one detector shown includes a photoelectric detector, and the test fluid is analyzed by light information obtained by the photoelectric detector.
[0072] The drop detection device may further include a processor, wherein the processor is configured to process the detection information of the detector to obtain and output the detection result. The processor may be connected to a display terminal (such as a mobile phone or a computer) to display the detection result on a real terminal for user viewing.
[0073] The embodiment of the present application also provides a test paper detection device, such as Figure 5-Figure 12 As shown, the test paper detection device includes a pushing device 4 and the above-mentioned drop detection device 7, wherein the pushing device 4 is configured to push the test paper assembly 6 to slide from the entrance 712 of the detection chamber 71 into the chamber 711, and can push the test paper assembly 6 out of the chamber 711. The installation structure of the drop detection device 7 and the pushing device 4 can be referred to Figure 1 and Figure 2 .
[0074] In one embodiment, the test paper testing device also includes a test paper storage container 1 for storing the test paper assembly 6, and the pushing device 4 is configured to push the test paper assembly 6 from the test paper storage container 1 to the testing chamber 71, and after the test is completed, push the test paper assembly 6 from the testing chamber 71 back to the test paper storage container 1.
[0075] The test paper detection device also includes a mounting body 2, and the test paper storage 1, the pushing device 4 and the drip detection device 7 are all mounted on the mounting body 2. Figure 5 and Figure 6As shown, the installation body 2 includes a box structure 21, a base 22 located below the box structure 21, and a support frame 23 installed on the base 22. The test paper storage 1 is installed in the box structure 21, the pushing device 4 is installed on the base 22, and the drop detection device 7 is installed on the support frame 23. Figure 4 The liquid drop detection device 7 has a mounting bracket 727 , and the liquid drop detection device is fixed to the support frame 23 via the mounting bracket 727 .
[0076] Figure 13-Figure 15 A test paper storage device 1 in an embodiment is shown, and the test paper storage device 1 includes a roller 11 that is rotatable relative to the mounting body 2, and a plurality of sliding mounting structures 111 are arranged on the outer surface of the roller 11 at intervals along the circumferential direction, and each sliding mounting structure 111 is configured to slidably mount the test paper assembly 6. When one of the test paper assemblies 6 on the roller 11 rotates to correspond to the pushing device 4, the pushing device 4 pushes the test paper assembly 6 from the roller 11 to the detection chamber 71 along the axial direction, and can push the test paper assembly 6 from the detection chamber 71 back to the roller 11, so as to realize the recovery of the discarded test paper assembly 6.
[0077] During use, the roller 11 can be set to rotate in one direction. Every time it rotates a certain angle, one of the unused test paper assemblies 6 is aligned with the pushing device 4. The pushing device 4 can push the unused test paper assembly 6 to the detection position. After the detection is completed, the pushing device 4 pushes the used test paper assembly 6 back to the roller 11. The test paper assembly 6 is used repeatedly for detection. After the multiple test paper assemblies 6 on the roller 11 are all used, the roller 11 is loaded with the used and discarded multiple test paper assemblies 6, and then the roller 11 can be processed centrally. The use of the test paper storage device 1 can solve the problem of environmental pollution caused by discarded test papers being used once and discarded once in the prior art.
[0078] The sliding mounting structure 111 on the roller 11 of the test paper storage device 1 can be a plurality of slide grooves provided on the outer surface of the roller 11, and the test paper device 6 can slide into and out of the slide grooves. In order to prevent the test paper assembly 6 from slipping out of the top opening of the slide groove, the side walls on both sides of the slide groove can be arranged to be inclined toward each other from bottom to top, so that the test paper assembly 6 can only enter and exit from the opening at one end of the slide groove. It can be understood that the sliding mounting structure 111 can also be other structures, for example, it can be a ridge provided on the outer surface of the roller 11, and a groove is provided on the test paper assembly 6, and the ridge can cooperate with the groove of the test paper assembly 6 for sliding installation.
[0079] In one embodiment, the test paper assembly 6 includes a loading body 61, a reaction layer 62 mounted on the loading body 61, and a diaphragm layer 63 on the side of the reaction layer 62 facing away from the loading body 61. When the test paper assembly 6 is mounted 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 of the detection chamber 71, thereby pushing the side of the test paper assembly 6 in the chamber 711 with the diaphragm layer 63 facing upward. In this way, the diaphragm layer 63 can be punctured and dripped on the upward side of the test paper assembly 6.
[0080] In one embodiment, the test paper detection device may further include a driving device 3 , and the driving device 3 is configured to drive the roller 11 to rotate relative to the installation body 2 .
[0081] In one example, if Fig. 9 As shown (combined Fig.16 and Fig.17 ), the driving device 3 includes a rotating shaft 32 rotatably mounted on the mounting body 2 and a driving motor 31 for driving the rotating shaft 32 to rotate; the test paper storage 1 is configured to be detachably mounted on the rotating shaft 32, and when the test paper storage 1 is mounted on the rotating shaft 32, the rotating shaft 32 drives the roller 11 to rotate. Therefore, after the multiple test paper assemblies 6 on the test paper storage 1 are used, the test paper storage 1 can be removed from the rotating shaft 32 to replace a new test paper storage 1, or the used test paper assemblies 6 can be centrally processed and replaced with new test paper assemblies 6.
[0082] In order to enable the drum 11 to be detachably mounted on the rotating shaft 32, Figure 13-Figure 15 In the example shown, a center hole 112 and an open groove 113 extending from the center hole 112 to one side of the drum 11 are provided at the center of the drum 11; the drum 11 allows the rotating shaft 32 to enter the center hole 112 through the open groove 113, and the drum 11 can be removed from the rotating shaft 32 through the open groove 113.
[0083] In order to enable the rotating shaft 32 to drive the drum 11 to rotate, a radially protruding protrusion 321 (see Fig.17 ), the protrusion 321 is located in the opening groove 113, so that when the rotating shaft 32 rotates, the protrusion 321 applies a rotational torque to the drum 11 to drive the drum 11 to rotate. Of course, the rotating shaft 32 and the center hole 112 of the drum 11 can also be arranged to be mutually matched polygonal structures, so that the rotation of the rotating shaft 32 can also drive the drum 11 to rotate.
[0084] In one example, the test paper storage device 1 further includes a cover shell 12 covering the drum 11 , and the cover shell 12 is configured to cover the outside of the drum 11 , so as to prevent the multiple test paper assemblies 6 on the drum 11 from being contaminated.
[0085] The bottom of the cover shell 12 is provided with a bottom opening 1212, and the end plates 122 of the cover shell 12 at both ends of the drum 11 are also provided with end openings 1221 respectively, and each end opening 1221 extends downward from a position corresponding to the center hole 112 to communicate with the bottom opening 1212, so that when the drum 11 of the test paper storage device 1 is installed on the rotating shaft 32 through the opening groove 113, the bottom opening 1212 and the end opening 1221 of the cover shell 12 can avoid the rotating shaft 32; wherein, the pushing device 4 is configured to push the test paper assembly 6 out of the drum 11 and push it back into the drum 11 from the bottom opening 1212 of the cover shell 12.
[0086] In one example, the housing 12 includes a cylinder 121 and end plates 122 located at both ends of the cylinder 121 , wherein the cylinder 121 has a chamber 1211 with a circular cross-section, and the drum 11 is located in the chamber 1211 .
[0087] In order to facilitate the placement and installation of the test paper storage device 1, the cover 12 may also include a bottom plate 123 located at the bottom of the cylinder 121 and at both sides of the bottom opening 1212. In addition, the cover 12 may also include a fixing portion 124 provided at the end of the cylinder 121 and radially protruding from the outer surface of the cylinder 121, and a connecting rib 125 connecting the fixing portion 124 at both ends, wherein the end plate 122 located at at least one end of the cylinder 121 may be fixed to the fixing portion 124 by bolts. Among them, the fixing portion 124 at the bottom of the cylinder 121 is connected by the bottom plate 123 as a connecting rib. The fixing portions 124 in a right angle are respectively provided at the four corners of the two ends of the cylinder 121. After the connecting rib 125 connects the fixing portion 124, the cover 12 is roughly a square structure.

[0102] Start the test, the roller sensor 81 senses that the roller 11 is installed in place, and the controller controls the drive motor 31 to operate after receiving the sensing information. The drive motor 31 drives the rotating shaft 32 to rotate, so that the roller 11 rotates. After the angle sensor 83 detects that 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 rotates to cooperate with the pushing claw 44 of the pushing device 4, and the pushing motor 41 drives the lead screw 42 to rotate, and the moving 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;
[0103] 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.
[0104] After the urine contacts the reaction layer 62 of the test paper assembly 6, the detector 714 in the detection chamber 71 detects the reaction information of the test paper assembly 6 and sends the detection information to the processor. The processor processes the data and obtains the detection result, and then sends the detection result to the display end.
[0105] After the detection is completed, the push motor 41 drives the lead screw 42 to rotate in the opposite direction, and the moving frame 43 moves from the second position to the first position, pushing the used test paper assembly 6 back to the roller 11.
[0106] 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 can be installed on the installation body 2 .
