Description

Technical Field

[0001] The present invention belongs to the technical field of medical instruments, and in particular relates to a portable three-in-one blood glucose, uric acid and blood ketone detection device. Background Art

[0002] To accommodate elderly users, home medical products must not only be user-friendly but also effective in handheld operation. For such multifunctional devices, compact design and suitable handheld operation make proper spatial layout particularly important. A single device can test three samples: blood glucose, blood ketones, and uric acid, eliminating the need to change devices for each test, making it more convenient.

[0003] Currently, the three-in-one blood glucose, blood ketone and uric acid detection devices on the market are generally integrated structures. In actual use, when the internal components of the detection device fail or individual components fail due to differences in the service life of each component, it is very inconvenient to repair and replace them. Generally, the entire device needs to be replaced, and the replacement cost is high. In addition, since this type of detection device requires blood sampling during detection, conventional integrated detection devices are not easy to clean.

[0004] After searching, in the prior art, the authorized patent document with announcement number CN208766186U and announcement date of 2019.04.19 discloses a three-in-one tester for blood glucose, blood ketones and uric acid. The tester described below refers to the three-in-one tester for blood glucose, blood ketones and uric acid. The tester includes a shell and an integrated circuit board, wherein the shell includes a front shell, a rear shell, a battery cover, a button, a strip withdrawal slider, a strip withdrawal pressure plate and a push button. The integrated circuit board includes a test strip terminal, a liquid crystal display screen and a terminal circuit board. In order to reduce the size of the device, the present application converts the sliding action of the strip withdrawal paddle in the test strip terminal to between the test strip terminal and the rear shell. The test paper reference is input into the device through the reference card. The test paper reference input port and the test strip socket of this device share one interface. The test strip terminal contains 6 contacts. Three types of test strips and one reference card each require 3 contacts to identify. Three of the 6 contacts are arranged for use, and there are 120 selection schemes. The test strip terminal can identify three types of test strips and one reference card and select four of them.

[0005] However, the device still has the following defects: when the internal components of the tester detection device fail or individual components fail due to differences in the service life of each component, it is very inconvenient to repair and replace them. Generally, the entire device needs to be replaced, which has a high replacement cost. In addition, the tester is not easy to clean due to its integrated design. Summary of the Invention

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides a portable three-in-one blood glucose, uric acid and blood ketone detection device, including a handheld component 1 and a detection component 2; for example, Figure 1-3 shown.

[0038] The handheld component 1 includes a handheld housing 101, on which a cover plate 102 is provided, and a clamping platform 103 is fixedly connected to the cover plate 102. The detection component 2 includes a main body housing 201, on which a display screen 202 is provided, and a plurality of control buttons 209 are also provided on the main body housing 201. A battery and an integrated circuit board are provided in the main body housing 201. A groove 203 is provided on the other side of the main body housing 201, and a dust cover 204 is provided on the groove 203. A charging interface 205 is provided in the groove 203, and the charging interface 205 is electrically connected to the battery. An extension plate 206 is fixedly connected to the side wall of the main body housing 201, and a conductive column 207 is fixedly connected to the bottom end of the extension plate 206, and the conductive column 207 is electrically connected to the integrated circuit board.

[0039] The bottom end of the host housing 201 is fixedly connected to a plug-in block 208, and a side wall of the plug-in block 208 is provided with a snap-in slot 2081. The cover 102 is fixedly connected to a snap-in platform 103, and the snap-in platform 103 is provided with a plug-in slot 1031. The plug-in slot 1031 is movably engaged with the plug-in block 208, and a limiting mechanism 104 is provided in the plug-in slot 1031.

[0040] Specifically, the handheld component 1 and the detection component 2 are detachably connected by providing a plug-in block 208 and a card-connecting platform 103. During use, if the detection component 2 is faulty or damaged, only the faulty part of the detection component 2 needs to be replaced, which is beneficial to the replacement of the detection component 2, can effectively reduce the replacement cost and increase convenience. On the other hand, since the detection component 2 is detachable, the handheld component 1 can be adapted to multiple different detection components 2, which increases the scalability of the detection device in different functions and saves costs. In addition, by arranging the integrated circuit board and the battery in the main body shell 201, when the handheld component 1 is contaminated and needs to be cleaned, the handheld component 1 and the detection component 2 can also be disassembled to facilitate the cleaning of the handheld component 1.

[0041] For example, Figure 4 and Figure 5 shown.

[0042] The limiting mechanism 104 includes a linkage plate 1041, one side wall of the linkage plate 1041 is fixedly connected to a handle 1045, the other side wall of the linkage plate 1041 is fixedly connected to a plurality of first sliding shafts 1042, the inner wall of the plug-in slot 1031 is provided with a plurality of first sliding slots 1032, and the plurality of first sliding slots 1032 are movably fitted with the plurality of first sliding shafts 1042 respectively, and the other ends of the plurality of first sliding shafts 1042 are fixedly connected to the first The wedge block 1043 has a first clearance groove 1033 formed on the inner wall of the insertion slot 1031. The first clearance groove 1033 movably fits with the two side walls of the first wedge block 1043. The first wedge block 1043 movably engages with the engaging groove 2081. A plurality of groups of first springs 1044 are provided between the first wedge block 1043 and the inner wall of the first clearance groove 1033. The plurality of groups of first springs 1044 are respectively sleeved on the plurality of groups of first sliding shafts 1042.

[0043] Specifically, by inserting the plug-in block 208 into the plug-in slot 1031 on the card-joining platform 103, the bottom end of the plug-in block 208 squeezes the first wedge block 1043, causing the first wedge block 1043 to slide into the first yielding slot 1033. When the card-joining slot 2081 provided on the plug-in block 208 moves to the first wedge block 1043, due to the tension of the plurality of first springs 1044, the first wedge block 1043 moves outward into the card-joining slot 2081, so that the plug-in block 208 is engaged and limited in the plug-in slot 1031, completing the detection assembly 2. When the detection component 2 needs to be removed from the handheld component 1 through the plug-in operation with the handheld component 1, it is only necessary to pull the handle 1045 to make the linkage plate 1041 drive the first sliding shafts 1042 to move, so that the first wedge block 1043 moves synchronously and slides into the first make way groove 1033. At this time, pull the plug-in block 208 to disengage it from the clamping platform 103 to complete the disassembly between the detection component 2 and the handheld component 1. The plug-in method avoids the tedious installation and disassembly of the traditional screw connection method that requires tools, thereby improving the convenience of using the detection device.

[0044] For example, Figure 6 and Figure 7 shown.

[0045] The inner wall of the handheld housing 101 is fixedly connected to a first partition 105. The first partition 105 is provided with a conductive portion 106. The conductive portion 106 includes a conductive rod 1061. The conductive rod 1061 passes through the first partition 105 and is slidably connected to the first partition 105. A first conductive contact 1062 is fixedly connected to the top of the conductive rod 1061. A second spring 1063 is provided between the first conductive contact 1062 and the first partition 105. The second spring 1063 is sleeved on the conductive rod 1061. The first conductive contact 1062 movably contacts the bottom end of the conductive column 207. The bottom end of the conductive rod 1061 is provided with a second conductive contact 1064.

[0046] Specifically, when the detection component 2 is plugged into the handheld component 1, the conductive column 207 passes through the cover 102 and extends into the handheld shell 101. The conductive column 207 contacts the first conductive contact 1062 and squeezes it, so that the conductive rod 1061 drives the second conductive contact 1064 to move downward for electrical connection.

[0047] The inner wall of the handheld housing 101 is fixedly connected to a second partition 107, which is arranged directly below the first partition 105. A fixing plate 109 is provided on the second partition 107, and a plurality of groups of limiting columns 1010 are fixedly connected to the fixing plate 109. Two groups of fixed shafts 1011 are provided on the fixing plate 109, and one end of each group of the fixed shafts 1011 is fixedly connected to a limiting block 1012. A telescopic airbag 1014 is sleeved on one group of the fixed shafts 1011, and one end of the telescopic airbag 1014 is sealed with the limiting block 1012. The telescopic airbag 1014 is connected to an air guide tube 1015.

[0048] A test paper placement mechanism 108 is provided on the second partition 107, and the test paper placement mechanism 108 includes a placement box 1081. The placement box 1081 is an open box. One end of the placement box 1081 passes through the side wall of the handheld housing 101 and extends to the outside of the handheld housing 101. Both side walls of the placement box 1081 are fixedly connected with sliders 1084. Two groups of sliders 1084 are slidably connected to two groups of fixed shafts 1011 respectively. A third spring 1016 is provided between the two groups of sliders 1084 and the fixed plate 109. The two groups of third springs 1016 are respectively sleeved on the two groups of fixed shafts 1011. One end of the telescopic airbag 1014 is sealed with a group of sliders 1084. A cavity is opened in the placement box 1081, and one end of the air guide tube 1015 is communicated with the cavity in the placement box 1081.

[0049] The placement box 1081 is provided with a placement slot 1082, into which a test strip 1083 is clamped. The test strip 1083 includes, but is not limited to, test strips for detecting blood sugar, blood ketones, and uric acid. The metal electrode on the test strip 1083 movably contacts the second conductive contact 1064. The bottom end of the inner wall of the placement slot 1082 is provided with a plurality of groups of air holes 1085, which are in communication with the cavity of the placement box 1081.

[0050] Specifically, according to the detection requirements, the corresponding test paper 1083 is selected and placed in the placement slot 1082, and the blood sample is dripped onto the sample suction port on the test paper 1083 so that the blood drop completely covers the sample suction port. The placement box 1081 is pushed to enter the interior of the handheld housing 101. When the placement box 1081 moves, a group of sliders 1084 drives the telescopic airbag 1014 to stretch, so that air enters the cavity of the placement box 1081 through several groups of air holes 1085, and then enters the telescopic airbag 1014 through the air guide tube 1015. The surface of the plurality of air holes 1085 is formed with negative pressure, so that the test paper 1083 is firmly attached to the placement groove 1082, thereby improving the stability during the detection process. At this time, the detection component 2 is plugged into the handheld component 1, so that the conductive column 207 pushes the conductive part 106 to move downward, so that the second conductive contact 1064 contacts the metal electrode of the test paper 1083, thereby completing the electrical connection between the test paper and the integrated circuit board, and performing corresponding blood sugar, blood ketone or uric acid tests on the blood sample on the test paper 1083.

[0051] For example, Figure 8 and Figure 9 shown.

[0052] An abutting groove 1071 and a second giving way groove 1072 are formed inside the second partition plate 107. The abutting groove 1071 and the second giving way groove 1072 are communicated with each other. A contact plate 1017 is slidably connected in the abutting groove 1071. One end of the contact plate 1017 is fixedly connected to an extrusion plate 1018. The extrusion plate 1018 passes through the side wall of the handheld housing 101 and extends to the outside of the handheld housing 101. The extrusion plate 1018 is movably fitted in the second giving way groove 1072.

[0053] The second partition plate 107 is provided with a clamping portion 1013, and the clamping portion 1013 includes a second wedge block 10131 and a third wedge block 10132. The second wedge block 10131 is movably clamped with the slider 1084, and the third wedge block 10132 is movably in contact with the contact plate 1017. A second sliding shaft 10133 is fixedly connected between the second wedge block 10131 and the third wedge block 10132. The second partition plate 107 is provided with a third yielding groove 1073, a second The sliding groove 1074 and the fourth giving groove 1075, the third giving groove 1073 and the two side walls of the third wedge block 10132 are movably fitted, the second sliding groove 1074 and the second sliding shaft 10133 are movably fitted, and the fourth giving groove 1075 and the two side walls of the second wedge block 10131 are movably fitted. A fourth spring 10134 is provided between the second wedge block 10131 and the inner wall of the fourth giving groove 1075, and the fourth spring 10134 is sleeved on the second sliding shaft 10133;

[0054] Specifically, the placement box 1081 is pushed into the handheld housing 101, and the slider 1084 moves synchronously until it contacts and squeezes the second wedge block 10131, causing the second wedge block 10131 to enter the fourth clearance groove 1075. When the slider 1084 disengages from the top of the second wedge block 10131, the tension of the fourth spring 10134 causes the second wedge block 10131 to move upward and engage with the slider 1084. Combined with the tension of the third spring 1016, the placement box 1081 is firmly fixed in the handheld housing 101.

[0055] Furthermore, when the placement box 1081 needs to be taken out, the extrusion plate 1018 is pushed to move the contact plate 1017 and squeeze the third wedge block 10132, so that the third wedge block 10132 moves downward, thereby driving the second wedge block 10131 to move downward into the fourth yielding groove 1075 and disengage from the slider 1084. Due to the tension of the third spring 1016, the two sets of sliders 1084 drive the placement box 1081 to pop out.

[0056] The portable three-in-one blood glucose, uric acid and blood ketone detection device proposed by the present invention works as follows:

[0057] According to the detection requirements, the corresponding test paper 1083 is selected and placed in the placement slot 1082. The blood sample is dripped onto the sample suction port on the test paper 1083 so that the blood drop completely covers the sample suction port. The placement box 1081 is pushed to enter the interior of the handheld housing 101. As the placement box 1081 moves, a set of sliders 1084 drives the telescopic airbag 1014 to stretch, allowing air to enter the cavity of the placement box 1081 through several groups of air holes 1085, and then enter the telescopic airbag 1014 through the air guide tube 1015. A negative pressure is formed on the surface of the plurality of groups of air holes 1085, so that the test paper 1083 fits firmly in the placement groove 1082, improving the stability during the detection process. At this time, the detection component 2 is plugged into the handheld component 1, so that the conductive column 207 pushes the conductive part 106 to move downward, so that the second conductive contact 1064 contacts the metal electrode of the test paper 1083, thereby completing the electrical connection between the test paper and the integrated circuit board, and performing corresponding blood sugar, blood ketone or uric acid tests on the blood sample on the test paper 1083.

[0058] The placement box 1081 is pushed into the interior of the handheld housing 101, and the slider 1084 moves synchronously until it contacts and squeezes the second wedge block 10131, so that the second wedge block 10131 enters the fourth yielding groove 1075. When the slider 1084 is disengaged from the top of the second wedge block 10131, due to the tension of the fourth spring 10134, the second wedge block 10131 moves upward to engage the slider 1084, and cooperates with the tension of the third spring 1016 to firmly fix the placement box 1081 in the handheld housing 101.

[0059] When the placement box 1081 needs to be taken out, the extrusion plate 1018 is pushed to move the contact plate 1017 and squeeze the third wedge block 10132, so that the third wedge block 10132 moves downward, thereby driving the second wedge block 10131 to move downward into the fourth yielding groove 1075 and disengage from the slider 1084. Due to the tension of the third spring 1016, the two groups of sliders 1084 drive the placement box 1081 to pop out.

[0060] By inserting the plug-in block 208 into the plug-in slot 1031 on the clamping platform 103, the bottom end of the plug-in block 208 squeezes the first wedge block 1043, causing the first wedge block 1043 to slide into the first yielding slot 1033. When the clamping slot 2081 provided on the plug-in block 208 moves to the first wedge block 1043, due to the tension of the plurality of first springs 1044, the first wedge block 1043 moves outward into the clamping slot 2081, so that the plug-in block 208 is clamped and limited in the plug-in slot 1031, completing the detection assembly 2 and the hand. The plug-in operation of the holding component 1 is performed. When the detection component 2 and the hand-held component 1 need to be removed, it is only necessary to pull the handle 1045 to make the linkage plate 1041 drive the first sliding shafts 1042 to move, so that the first wedge block 1043 moves synchronously and slides into the first yield groove 1033. At this time, pull the plug-in block 208 to disengage it from the clamping platform 103 to complete the disassembly between the detection component 2 and the hand-held component 1. The plug-in method avoids the tedious installation and disassembly of the traditional screw connection method that requires tools, thereby improving the convenience of using the detection device.

[0061] By setting the plug-in block 208 and the card-connecting platform 103, the handheld component 1 and the detection component 2 are detachably connected. During use, if the detection component 2 is faulty or damaged, only the faulty part of the detection component 2 needs to be replaced, which is beneficial to the replacement of the detection component 2, can effectively reduce the replacement cost and increase convenience. On the other hand, since the detection component 2 is detachable, the handheld component 1 can be adapted to multiple different detection components 2, which increases the scalability of the detection device in different functions and saves costs. In addition, by arranging the integrated circuit board and the battery in the main body shell 201, when the handheld component 1 is contaminated and needs to be cleaned, the handheld component 1 and the detection component 2 can also be disassembled to facilitate the cleaning of the handheld component 1.
