Description

Technical Field

[0001] This invention relates to the field of diabetes detection technology, and more specifically to a rapid diabetes detection device. Background Technology

[0002] Diabetes is a growing problem worldwide, posing a significant threat to human health. This disease is easily influenced by a patient's dietary habits, and patients often cannot properly manage their diet, which can unintentionally worsen their condition and cause considerable harm. Currently, the main methods for detecting diabetes are blood glucose testing, urine testing, and testing of the patient's exhaled breath. Results from exhaled breath testing are easily affected by environmental and other factors. Urine testing is time-consuming, laborious, and cumbersome. Blood glucose testing, on the other hand, is relatively accurate and easy to perform. Common blood glucose testing methods include electrochemical blood glucose meters, such as a real-time blood glucose monitoring device with publication number CN119214646A. These devices collect blood from the patient's fingertip for blood glucose testing. However, some patients have poor peripheral circulation due to shock or low blood pressure, and existing blood glucose meters often have a fixed fingertip puncture depth, making blood collection difficult and results unreliable. Furthermore, to prevent blood infection, the lancet used for puncture needs to be replaced after each use, but existing blood glucose meters do not allow for lancet replacement, leading to inconvenience. Summary of the Invention

[0003] To address the aforementioned problems, this invention aims to provide a rapid diabetes testing device. It features a multi-functional blood collection mechanism with a replaceable and adjustable puncture needle assembly inside the housing. This allows for adjustment of the puncture depth according to actual conditions, and the puncture needle assembly is replaced after each test. Simultaneously, a disinfection assembly disinfects the needle tip area. Furthermore, a test strip holding mechanism is designed, with a test platform inside the housing for holding the test strip at the detection end. When the housing and base are unfolded, the test platform moves directly below the blood dropper of the puncture needle assembly to collect the extracted blood. The test platform resets after testing for easy removal of the used test strip. This device offers advantages such as wide applicability, high safety, and ease of use.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rapid diabetes testing device includes a housing, a base located below the housing, a detection element located inside the housing, a display screen and control buttons located above the housing, a multi-functional blood collection mechanism located inside the housing, and a test strip holding mechanism located inside the housing.

[0005] The multifunctional blood collection mechanism includes a sliding plate slidably disposed on one side of the housing, a horizontal mounting plate disposed in the middle of the vertical section of the sliding plate, a puncture needle assembly disposed on the mounting plate, and an electromagnetic component for driving the puncture needle assembly disposed in the middle of the mounting plate.

[0006] The puncture needle assembly includes a spiral blood collection tube with a drive spring inside. A puncture needle and a connecting valve are connected to each end of the spiral blood collection tube. A puncture needle retaining plate is slidably mounted on the mounting plate at the end furthest from the center of the housing. The puncture needle is mounted on the puncture needle retaining plate via a retaining element. A connecting valve limiting ring is located on the mounting plate near the center of the housing. By retaining the puncture needle on the puncture needle retaining plate and the connecting valve on the connecting valve limiting ring, the puncture needle retaining plate is attracted by an electromagnetic component, causing the puncture needle to move towards the center of the housing and compress the drive spring inside the spiral blood collection tube. De-energizing the electromagnetic component releases the puncture needle retaining plate, which then moves to contact the sliding plate, allowing the puncture needle to pass through a hole in the vertical section of the sliding plate for puncture.

[0007] Based on the above technical solution, the sliding plate is further provided with a puncture needle limiting bolt threadedly connected to it; by rotating the puncture needle limiting bolt, the maximum length of the puncture needle that can extend from the side of the sliding plate can be adjusted, so as to adjust the puncture depth of the puncture needle.

[0008] Based on the above technical solution, the puncture needle is further provided with a blood collection layer, and multiple blood collection holes are provided at the interval between the tail of the puncture needle and the blood collection layer.

[0009] The multifunctional blood collection mechanism also includes a blood drip tube connected to the bottom of the connecting valve. Inside the housing, there is also an air pump connected to the end of the connecting valve away from the spiral blood collection tube. The other end of the air pump is equipped with an air pump. A breathable membrane is provided at the connection point between the connecting valve and the air pump. After the puncture needle is inserted, the air pump draws gas from the air pump, creating a negative pressure in the air pump, connecting valve, and spiral blood collection tube to draw blood. The blood enters the connecting valve, is blocked by the breathable membrane, and flows down from the blood drip tube for subsequent diabetes testing. After the test is completed, the sliding plate is pulled out of the housing and a new puncture needle assembly is replaced.

[0010] Based on the above technical solution, a pressure sensor is further provided on the puncture needle limiting bolt. When the puncture needle retaining plate is released by the electromagnetic component, it can fit with the pressure sensor to start the air pump.

[0011] The multifunctional blood collection mechanism also includes a disinfection component. This component includes a disinfectant chamber located on the horizontal section of a sliding plate. A piston chamber is located at the top of the disinfectant chamber, and a piston rod is slidably mounted within it. One end of the piston rod extending out of the piston chamber is connected to the bottom end of a puncture needle retaining plate. An infusion tube is connected to the side of the piston chamber. A piece of disinfectant cotton, pierced by a puncture needle, is mounted on the sliding plate. The end of the infusion tube away from the piston chamber is connected to the disinfectant cotton on the sliding plate. A one-way valve is located at the connection between the piston chamber and the disinfectant chamber. When the electromagnetic component attracts the puncture needle retaining plate, it moves the piston rod into the piston chamber, delivering the disinfectant solution from the piston chamber to the disinfectant cotton via the infusion tube for disinfection. When the electromagnetic component releases the puncture needle retaining plate for puncture, the piston rod moves outward from the piston chamber, creating a negative pressure inside the piston chamber and replenishing the disinfectant solution from the disinfectant chamber to the piston chamber for disinfection during the next puncture.

[0012] The test strip snap-fit ​​mechanism includes a test strip snap-fit ​​base slidably disposed inside the housing. The housing has a test strip insertion hole. Inside the housing and below the test strip insertion hole, there is a test strip guide groove that fits into one end of the test strip snap-fit ​​base. Inside the housing, there is also a snap-fit ​​base adjustment component for moving the test strip snap-fit ​​base after snapping in the test strip to directly below the blood dropper. In the initial state, the test strip snap-fit ​​base fits into the test strip guide groove. The end of the test strip used for blood testing is inserted from the test strip insertion hole and inserted along the test strip guide groove until it snaps into the test strip snap-fit ​​base. The snap-fit ​​base adjustment component moves the snap-fit ​​base directly below the blood dropper to collect the drawn blood and perform diabetes testing.

[0013] The card holder adjustment assembly includes an air bladder disposed inside the housing. A connecting shaft is disposed on the base, which penetrates into the housing and can compress the air bladder. An adjustment cavity is disposed at the end of the housing away from the air bladder. Multiple air supply tubes are connected between the air bladder and the adjustment cavity. A telescopic tube is disposed on one side of the adjustment cavity. The end of the telescopic tube away from the adjustment cavity is connected to the test strip card holder. By moving the fitted base away from the housing, the top of the connecting shaft compresses the air bladder. The gas in the air bladder enters the adjustment cavity through the air supply tubes, causing the telescopic tube to extend, thereby pushing the test strip card holder with the test strip attached to it directly below the blood dropper.

[0014] Based on the above technical solution, further, a storage slot for storing multiple spare puncture needle assemblies is slidably provided on one side of the base.

[0015] The beneficial effects of this invention are: 1. This application features a multi-functional blood collection mechanism. An adjustable puncture needle assembly is installed on a sliding plate on one side of the housing. During use, the test strip is inserted into the housing through the test strip insertion hole, and the electromagnetic component is activated to attract the puncture needle retaining plate, retracting the puncture needle into the housing. The electromagnetic component is then deactivated, and the puncture needle retaining plate resets the puncture needle, allowing it to exit from the side of the housing for puncture. A pressure sensor activates an air pump to automatically draw blood for diabetes detection using an electrochemical detection method. This design offers the advantage of ease of use. 2. By setting a puncture needle clamping plate and a connecting valve limiting ring on the mounting plate, after a blood test is completed, the sliding plate is pulled out from one side of the housing, and the puncture needle, spiral blood collection tube, connecting valve and the blood drip tube below it are replaced as a whole, and a new sterile cotton is replaced. After the replacement is completed, the sliding plate is pushed back into the housing to reset. When pushed in, the sterile cotton is automatically replenished with disinfectant for the next puncture, which makes this application have the advantage of strong safety. 3. By setting a puncture needle limiting bolt on the sliding plate, the maximum distance that the puncture needle can pass through the hole on the vertical section of the sliding plate can be adjusted by rotating and adjusting the puncture needle limiting bolt during actual use. That is, the puncture depth of the puncture needle can be adjusted, so that this application can be applied to patients in different situations, avoid inaccurate test results due to insufficient puncture depth, and has a wider range of applications.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] The inventors discovered that most common blood glucose tests are conducted using electrochemical methods. These devices collect blood glucose from the patient's fingertip. However, some patients have poor peripheral circulation due to shock or low blood pressure, and existing blood glucose meters often require a fixed puncture depth, making blood collection difficult and the results unreliable. Furthermore, to prevent blood infection, the lancet used for puncture needs to be replaced after each use, but existing blood glucose meters do not allow for lancet replacement, resulting in inconvenience.

[0020] Based on the above findings, this application proposes a rapid diabetes testing device. It features a multi-functional blood collection mechanism with a replaceable and adjustable puncture needle assembly inside the housing. This allows for adjustment of the puncture depth according to actual conditions, and the puncture needle assembly is replaced after each test. Simultaneously, a disinfection assembly disinfects the needle tip area. Furthermore, a test strip holding mechanism is designed, with a test platform inside the housing for holding the test strip at the detection end. When the housing and base are unfolded, the test platform moves directly below the blood dropper of the puncture needle assembly to collect the extracted blood. The test platform resets after testing for easy removal of the used test strip. This device offers advantages such as wide applicability, high safety, and ease of use.

[0021] Example 1: See Figure 1 and Figure 2 This application discloses a rapid diabetes detection device, including a housing 1, which is a hollow shell structure with a shape close to a cuboid and can be made of high-strength materials such as plastic. A base 2 is provided below the housing 1. The base 2 is a plate structure that is adapted to the shape of the housing 1 and is made of the same material. In this embodiment, a storage groove 201 is slidably provided in the middle of the base 2. The storage groove 201 can be used to place multiple spare puncture needle assemblies for rapid diabetes detection through the device of this application. A multifunctional blood collection mechanism 3 for puncturing the patient's finger and collecting blood is provided inside the housing 1. A test strip snapping mechanism 4 is also provided inside the housing 1. The test strip snapping mechanism 4 is used to snap the detection end of the test strip 7 and move the test strip 7 to the bottom of the multifunctional blood collection mechanism 3 to collect the drawn blood.

[0022] Example 2: See Figure 3 , Figure 4 , Figure 5 as well as Figure 13 The housing 1 is provided with a test strip snap-fit ​​mechanism 4 for snapping and fixing the test strip 7 used for rapid diabetes testing; the test strip snap-fit ​​mechanism 4 includes a test strip snap-fit ​​base 401, which is a plastic paper base structure, and its upper part is provided with a snap-fit ​​groove structure adapted to the size of the test strip 7 used in this application. In this embodiment, a straight sliding groove can be opened at the center line of the bottom surface of the housing 1 to snap the bottom of the test strip snap-fit ​​base 401 into the sliding groove, so that it can slide and adjust along the housing 1; A test strip insertion hole 402 is provided at the top of the housing 1. At the same time, a first test strip guide groove 403 is fixed on the inner top surface of the housing 1 at a position that matches the test strip insertion hole 402. The test strip guide groove 403 is a groove structure with a certain curvature. Its bottom height is adapted to the test strip card holder 401. When the test strip card holder 401 is in contact with the bottom of the test strip guide groove 403, the test strip 7 is inserted into the test strip guide groove 403 from the test strip insertion hole 402. The detection end for collecting blood can be inserted into the card slot structure at the top of the test strip card holder 401 along the arc surface structure of the test strip guide groove 403. The test strip clipping mechanism 4 also includes a clipping seat adjustment component disposed inside the housing 1. The clipping seat adjustment component enables the test strip clipping seat 401 with the test strip 7 clipped to move directly below the multi-functional blood collection mechanism 3. The clipping seat adjustment component includes an airbag 404 disposed inside the housing 1. In this embodiment, a vertically arranged connecting shaft 405 is fixed above the base 2. The shaft of the connecting shaft 405 passes through the inside of the housing 1, and a horizontal circular plate is fixed at the top of its shaft. Meanwhile, the airbag 404 is an annular airbag structure, which is sleeved on the shaft of the connecting shaft 405. When the bottom of the housing 1 is in contact with the base 2, the circular plate at the top of the connecting shaft 405 will not exert a squeezing effect on the airbag 404. The airbag 404 is in a state of inflation due to the gas inside it. When the housing 1 and the base 2 move away from each other, the connecting shaft 405 is pulled out of the housing 1, and the circular plate at its top will squeeze the airbag 404. A hollow adjustment cavity 406 is provided on the bottom surface inside the housing 1, away from the airbag 404 (near the bottom of the vertical guide groove 403 in the attached drawing). A pair of air supply pipes 407 are connected to both sides of the adjustment cavity 406. The ends of the two air supply pipes 407 away from the adjustment cavity 406 are connected to the bottom sides of the airbag 404. When the airbag 404 is compressed by the connecting shaft 405, the gas inside it can be transported to the adjustment cavity 406 through the air supply pipes 407. Simultaneously, a fixed section is located on the side of the adjustment cavity 406, i.e., between the two air supply pipes 407. A telescopic tube 408 is provided. The telescopic tube 408 is a horizontally arranged multi-segment telescopic rod structure. Its fixed section is fixed to the side of the adjustment cavity 406, and its sliding section is connected to the test strip card holder 401. When gas is filled into the adjustment cavity 406, the gas inside will enter the telescopic tube 408 and cause it to extend, thereby pushing the test strip card holder 401 to move away from the test strip guide groove 403, and driving the detection end of the test strip 7 to move directly below the blood output of the puncture needle assembly in the multifunctional blood collection mechanism 3, so as to collect blood for diabetes testing.

[0023] In this embodiment, a detection element 8 is provided inside the housing 1. The detection element 8 includes multiple components for detecting blood on the test strip 7 by electrochemical detection. At the same time, a display screen 5 and control buttons 6 are also provided on the top of the housing 1. In this application, the selection and specific settings of the detection element 8, display screen 5, control buttons 6 and test strip 7 can be referenced from existing blood glucose meters and other products. This is the prior art that has been disclosed and is not the design point of this application. It is only used for illustrative purposes in this application.

[0024] Example 3: See Figure 6 and Figure 7 The multifunctional blood collection mechanism 3 includes a sliding plate 301, which is a vertical plate structure made of high-strength plastic. Its side cross-section is L-shaped, including a horizontal section and a vertical section. In this embodiment, a groove structure adapted to the sliding plate 301 is provided on the side of the housing 1, so that the horizontal section of the sliding plate 301 can slide and adjust along the groove. The limit distance of the sliding plate 301 sliding inward toward the housing 1 can make its vertical section form a complete vertical plane with the side of the housing 1. See Figure 10 A horizontally arranged mounting plate 302 is fixed in the middle of the vertical section of the sliding plate 301. A groove structure is provided in the middle of the mounting plate 302. The starting end of the groove structure coincides with the contact area between the sliding plate 301 and the mounting plate 302, and its ending end is located near the middle of the mounting plate 302. An electromagnetic component 303 is provided at the ending end of the groove structure. The electromagnetic component 303 is a common electromagnet product. In this embodiment, an electromagnetic switch 323 for controlling the opening or closing of the electromagnetic component 303 is provided on the side of the housing 1 opposite to the side where the sliding plate 301 is located. At the same time, a puncture needle assembly for inserting a patient's finger to draw blood is slidably arranged in the groove structure in the middle of the mounting plate 302. When the electromagnetic component 303 is turned on, it can attract the puncture needle assembly until it is in contact with the end of the electromagnetic component 303.

[0025] The puncture needle assembly includes a spiral blood collection tube 304, which is a soft hollow tube with good elasticity. A drive spring 305 is installed inside the tube. The drive spring 305 is a spring product with high elasticity, so that the spiral blood collection tube 304 forms the same spring-shaped structure. Considering that the amount of blood that can be extracted during fingertip blood collection is limited, in actual manufacturing, the diameter of the spiral blood collection tube 304 can be kept in the range of 1-2 mm, and its overall length in the extended state should be kept in the range of 3-5 cm, so as to be able to extract a sufficient amount of fingertip blood.

[0026] The spiral blood collection tube 304 is connected to a puncture needle 306 and a connecting valve 307 at both ends. The bottom of the connecting valve 307 (i.e., its side curved surface structure) is connected to a downwardly extending blood drop tube 312. The above-mentioned structure in the puncture needle assembly can form a replaceable puncture needle structure. When a patient completes the test, the above-mentioned puncture needle structure can be replaced. In this embodiment, in order to avoid the influence of the magnetic force of the electromagnetic component 303, the structural materials of the above-mentioned puncture needle assembly can be non-metallic or metal materials that have been treated with anti-magnetic attraction. See Figure 12 A puncture needle retaining plate 308 is slidably disposed in a groove structure located in the middle of the mounting plate 302. In this embodiment, the puncture needle retaining plate 308 includes a metal slider structure disposed in the groove structure. A circular plate structure is disposed on the top of the slider structure, and a vertical through groove is provided on the circular plate structure. At the same time, a connecting valve limiting ring 309 is disposed at one end of the mounting plate 302 away from the puncture needle retaining plate 308. The connecting valve limiting ring 309 is a fan-shaped annular structure adapted to the connecting valve 307. Therefore, when the puncture needle assembly is installed, the side curved surface of the connecting valve 307 can be inserted along the middle of the connecting valve limiting ring 309, and the puncture needle retaining member 311 is sleeved on the puncture needle 306. Pull the puncture needle retaining plate 308 slightly away from the sliding plate 301, and insert the puncture needle retaining piece 311 into the vertical through slot on the circular plate structure of the puncture needle retaining plate 308 until the puncture needle retaining piece 311 coincides with the circular part of the circular plate structure. Then release the puncture needle retaining plate 308, allowing the puncture needle 306 to pass through the hole on the sliding plate 301. At this time, the puncture needle 306, the spiral blood collection tube 304, and the connecting valve 307 can be installed above the mounting plate 302 in a state parallel to it. When the electromagnetic component 303 is energized and opened, it can attract the puncture needle retaining plate 308, causing the puncture needle 306 to retract into the housing 1, and compressing the spiral blood collection tube 304 and the drive spring 305. (See reference...) Figure 14 When the patient passes through the space formed by the unfolded shell 1 and base 2 and places their index finger on the hole of the sliding plate 301, the electromagnetic component 303 is turned off. Under the elastic force of the drive spring 305, the puncture needle retaining plate 308 moves towards the vertical section of the sliding plate 301 and drives the puncture needle 306 to pass through the hole of the sliding plate 301 to puncture the patient's finger so that blood can be extracted from the finger later.

[0027] See Figure 8In this embodiment, a puncture needle limiting bolt 310 is also installed on the hole in the sliding plate 301 by means of a threaded connection. The hole in the middle of the puncture needle limiting bolt 310 allows the puncture needle 306 and the puncture needle retainer 311 to pass through. Its end near the inside of the housing 1 can block the puncture needle retainer plate 308. Thus, this application can adjust the maximum length of the puncture needle 306 that can extend from the vertical section of the sliding plate 301 by rotating the puncture needle limiting bolt 310, so as to adjust the puncture depth of the puncture needle 306 into the finger, so as to make it suitable for patients with different physical conditions.

[0028] In this embodiment, the puncture needle 306 is a solid blunt medical needle. Its tail end is engaged with the platform structure of the puncture needle engaging plate 308, which has a hollow structure inside. This hollow structure communicates with the head end of the spiral blood collection tube 304. A blood collection layer 326 is sleeved around the outside of the needle body of the puncture needle 306. The blood collection layer 326 is a tubular structure, with its head end flush with the needle tip of the puncture needle 306 and its tail end connected to the platform structure at the tail end of the puncture needle 306. The inner... The wall of the blood collection layer 326 is spaced from the outer wall of the puncture needle 306, and multiple blood collection holes connected to the cavity structure at the tail of the puncture needle 306 are provided at the blood collection layer 326 away from the needle tip of the puncture needle 306. A soft threaded tube section is provided at one end of the blood collection layer 326 near the needle tip of the puncture needle 306. When the puncture needle retaining plate 308 is reset and drives the needle tip of the puncture needle 306 to pierce the finger, it can squeeze the threaded tube section of the blood collection layer 326, causing the overall length of the blood collection layer 326 to shrink. A micro-motion spring 325 is also provided inside the puncture needle limiting bolt 310. When the puncture needle 306 quickly pierces the finger under the reset action, the platform structure at its tail end can compress the micro-motion spring 325. When the puncture needle 306 stops piercing, it can be slightly pulled outward from the puncture site of the finger under the elastic force of the micro-motion spring 325 to allow blood to seep out. At the same time, the threaded tube section at the front end of the blood collection layer 326 returns to its initial length through its own elastic force. During this period, the front end of the blood collection layer 326 can always keep in close contact with the periphery of the puncture site of the finger, allowing blood to seep out through the puncture site. The fluid can flow in along the gap between the blood collection layer 326 and the puncture needle 306, so that blood can be drawn out by negative pressure. In addition, a soft buffer ring 324 is provided at the end of the puncture needle limiting bolt 310 that protrudes from the outside of the housing 1. The buffer ring 324 is a rubber ring, and the maximum inner diameter of the buffer ring 324 is slightly larger than the outer diameter of the puncture needle 306. When blood is collected, the patient can press his finger against the buffer ring 324 to form a certain sealing effect in the area where the needle tip of the puncture needle 306 is located, thereby improving the blood collection effect of the puncture needle 306.

[0029] An air pump 313 is also installed inside the housing 1 and is secured by an air pump retainer 101. The air pump 313 is horizontally positioned, with one end connected to the end of the connecting valve 307 away from the spiral blood collection tube 304 via a valve body. The end away from the connecting valve 307 is connected to an air pump 314. The air pump 314 can refer to the miniature air pump product "Murata MZB1001T02". It is fixed to the housing 1 and can draw the gas out of the air pump 313 when it is started, so that a negative pressure is formed inside the air pump 313. See Figure 11 In this embodiment, a pressure sensor 316 is also provided on one end of the puncture needle limiting bolt 310 located inside the housing 1. The pressure sensor 316 can refer to the miniature thin film pressure sensor product of "TDK EPCOS C39 series". Multiple pressure sensors can be set on the puncture needle limiting bolt 310 by means of bonding or other methods. The pressure sensor 316 can be connected to the air pump 314 by existing technology in conjunction with the controller and other products. When the puncture needle retaining plate 308 is released and rebounded by the electromagnetic component 303 and comes into contact with the puncture needle limiting bolt 310, the pressure sensor 316 can be triggered to start the air pump 314. In addition, a switch for manually controlling the air pump 314 can also be provided on the housing 1. See Figure 9 A breathable membrane 315 is provided at the end of the connecting valve 307 near the suction cylinder 313. The breathable membrane 315 allows gas to pass through but isolates liquid. When the air pump 314 is started and a negative pressure is formed in the suction cylinder 313, a negative pressure can be generated simultaneously in the connecting valve 307 and the spiral blood collection tube 304. This allows blood flowing into the gap between the blood collection layer 326 and the puncture needle 306 to be drawn through the blood collection port. When the blood enters the connecting valve 307 along the spiral blood collection tube 304... During the test, due to the isolation effect of the breathable membrane 315, blood will flow into the blood dropper 312 and drip down onto the detection end of the test strip 7 on the test strip card holder 401 to test the patient's blood. After one test is completed, the sliding plate 301 is pulled out from one side of the housing, and the puncture needle structure consisting of the puncture needle 306, the spiral blood collection tube 304, the connecting valve 307, and the blood dropper 312 is replaced. The test strip 7 is then removed from the housing 1 and replaced before the next test can be performed.

[0030] It should be noted that when collecting blood from the fingertip, this application does not require the blood volume to fill the entire spiral blood collection tube 304. Even if the amount of blood extracted is small, the blood entering the spiral blood collection tube 304 can still be drawn into the blood dropper 312 by the subsequent negative pressure suction effect and the outside air. When the amount of blood from the fingertip is small, the operator can actively press the base of the finger being collected with the other hand so that the blood can overflow from the puncture site.

[0031] The multifunctional blood collection mechanism 3 also includes a disinfection component. The disinfection component includes a disinfection liquid chamber 317 disposed on the horizontal section of the sliding plate 301. The disinfection liquid chamber 317 is filled with disinfectant. A piston chamber 318 is disposed above it. The piston chamber 318 is a horizontally disposed cylindrical body. One end of the piston chamber 318 is connected to the top of the disinfection liquid chamber 317. A piston rod 319 is slidably disposed in the piston chamber 318. In this embodiment, a vertical rod is disposed at the bottom of the metal slider of the puncture needle retaining plate 308. The bottom end of the vertical rod is connected to the end of the piston rod 319 that extends out of the piston chamber 318. When the puncture needle retaining plate 308 is attracted or released by the electromagnetic component 303, it can also drive the piston rod 319 to slide in the piston chamber 318. In this embodiment, infusion tubes 320 are connected to both sides of the piston chamber 318 near the end that communicates with the disinfectant chamber 317. The other ends of the two infusion tubes 320 extend upward through the mounting plate 302 and pass through the vertical section of the sliding plate 301. At the same time, a disinfectant cotton swab with a central opening is also fixed to the outside of the vertical section of the sliding plate 301. A one-way valve 322 is provided at the connection between the piston chamber 318 and the disinfectant chamber 317, so that the disinfectant in the disinfectant chamber 317 can flow into the piston chamber 318 in one direction. When the puncture needle clamping plate 308 is attracted by the electromagnetic component 303, When the piston rod 319 moves into the piston chamber 318, the disinfectant in the piston chamber 318 is delivered to the disinfectant cotton 321 through the infusion tube 320. The patient can press the surface of the disinfectant cotton 321 with their finger to disinfect the puncture site. When the electromagnetic component 303 releases the puncture needle clamping plate 308 to puncture the finger, the piston rod 319 moves outward from the piston chamber 318, creating a negative pressure inside the piston chamber 318, which draws the disinfectant in the disinfectant chamber 317 into the piston chamber 318. After the test is completed, a new disinfectant cotton 321 is replaced so that the finger can be disinfected for the next monitoring.

[0032] Furthermore, it should be noted that for the electronic components such as electromagnetic component 303, air pump 314, and pressure sensor 316 mentioned in this application, corresponding power supply or controller products should also be installed in the housing 1 to ensure that the above-mentioned components can realize their basic functions. The specific product selection and setting method can refer to existing products or technologies. These are existing technologies and will not be elaborated in this application.

[0033] Working principle: Insert the test strip 7 into the test strip insertion hole 402 and separate the base 2 from the housing 1. When the exposed end of the test strip 7 is pulled into the housing 1 and stops, it indicates that the detection end of the test strip 7 has moved below the blood dropper 312. Activate the electromagnetic component 303 to attract the puncture needle retainer plate 308. At this time, the puncture needle 306 is retracted into the housing 1. The piston rod 319 squeezes the disinfectant in the piston chamber 318 to wet the disinfectant cotton swab 321. The patient inserts their hand into the space formed by the separation of the base 2 and the housing 1 and presses the fingertip of the finger to be punctured to disinfect it. The cotton 321 is disinfected and then attached to the hole of the sliding plate 301. Then the electromagnetic component 303 is turned off. The puncture needle retaining plate 308 is reset under the action of the drive spring 305 in the spiral blood collection tube 304, so that the puncture needle 306 is inserted into the fingertip. At the same time, the air pump 314 is started to draw blood. After the blood drips onto the detection end of the test strip 7, the test result is displayed on the display screen 5. After the test is completed, the sliding plate 301 is pulled out, and a new puncture needle structure and disinfectant cotton 321 are replaced, as well as a new test strip 7.
