Technical Field
[0001] The invention relates to the technical field of blood sugar testing devices, in particular to a painless minimally invasive blood sugar testing device. Background Art
[0002] A blood glucose meter, also known as a glucometer, is an electronic instrument that measures blood glucose levels. Based on their working principles, blood glucose meters are divided into two types: photoelectric and electrode types. The testing principle of electrode-type blood glucose meters is more scientific, and the electrodes can be built-in.
[0003] After searching, patent announcement number CN 215017523 U is a multifunctional blood sugar testing device. By configuring a pressure block, it realizes pressing on the finger, thereby providing convenience for squeezing bleeding of the finger, and by configuring a through hole at the bottom of the accommodating chamber, when the lancing pen is inserted into the through hole to prick the finger, the blood drips downward under the action of gravity, avoiding the first drop of blood flowing into the accommodating chamber, contaminating the accommodating chamber and the finger, and causing inconvenience in cleaning. By configuring the test paper on the same axis of the through hole, after the lancing pen pricks the finger, the test paper can be located directly below the through hole by rotating the rotating rod. Under the squeezing of the pressure block, the blood automatically drips on the test paper, which provides convenience for the blood to accurately drip onto the test paper.

[0016] In order to solve the above technical problems, the present invention also provides a method for using a painless minimally invasive blood sugar testing device, which includes the following steps:
[0017] Step 1: Through the cooperation between the limiting sleeve and the first placement groove, it is convenient for the user to insert the finger into the interior of the finger sleeve mechanism. During the insertion process, the first distance sensor is used to detect the progress of the finger entering, thereby triggering the anesthesia spray head to spray anesthesia spray on the finger to reduce the pain during blood collection. Then, the second distance sensor is used to detect the progress of the finger entering again, thereby triggering the operation of the pneumatic belt, and the pneumatic belt is used to press the fingertips of the user against the top of the blood collection hole;
[0018] Step 2: The cylinder drives the mounting shaft to move toward the blood collection hole. During the displacement process, the blood collection needle mechanism inside the needle storage box is pushed into the interior of the mounting sleeve by the pushing convex. At this time, the blood collection needle mechanism is fixed inside the second placement groove through the cooperation between the first mounting plate, the first spring, the first hook, and the hook groove. Finally, the blood collection needle mechanism pierces the user's fingertips for blood collection. After the fingertips are pierced, the cylinder is started to drive the mounting shaft to move toward the side away from the blood collection hole. During this displacement process, the first hook drives the blood collection needle mechanism to move. When the blood collection needle mechanism moves to one side of the discharge hole, the blood collection needle mechanism is thrown out from the inside of the discharge hole under the cooperation between the second spring and the second spring. The above steps are repeated to achieve the purpose of automatically replacing the blood collection needle mechanism. The displacement distance of the push rod inside the mounting shaft is limited by the cooperation between the second mounting pin and the slide groove.
[0019] Step 3: When the top of the axial mounting sleeve is displaced, the second mounting rod is pushed toward the inside of the first mounting rod under the action of the friction between the second mounting rod and the outer wall of the mounting sleeve. In the process of the second mounting rod displacing toward the inside of the first mounting rod, the third spring is prevented from pushing the second mounting rod to move upward through the cooperation between the second mounting sheet, the second hook and the fourth spring, so that the third spring contracts and accumulates force. When the second hook is displaced to one side of the unlocking groove, the fourth spring pulls the second hook to rotate toward the outside of the first mounting rod, so that the second hook and the first mounting rod are unlocked, and then the third spring drives the second mounting rod to rebound upward quickly, so that the blood collection needle mechanism quickly pierces the fingertips of the user, reducing the perception time of the nerve endings to the stimulation, thereby alleviating the pain.
[0020] Step 4: When the second hook pierces the user's fingertip, the piercing depth is limited by the second mounting block, and at the same time, the second mounting block is made to quickly hit the user's fingertip through the force storage mechanism, so that the pre-fragmented piece is broken, and then the second mounting block and the needle are pulled into the needle sleeve under the action of the fifth spring, so as to prevent the blood collection needle mechanism from being reused and prevent the user from being stabbed by the needle when handling the used needle. The rubber pad is used to buffer the impact between the needle sleeve and the second mounting block and the user's fingertip to reduce pain, and the displacement distance of the second mounting rod inside the first mounting rod is limited by the cooperation between the limiting column and the limiting groove;
[0021] Step 5: After the puncture is completed, the test paper in the paper storage slot is driven by the first guide wheel to move toward the blood collection hole, so that the test paper is inserted into the inside of the connection port and is at the bottom of the blood collection hole, and the blood leaked from the blood collection hole is collected for testing. After the test is completed, the test paper is driven by the second guide wheel to move to the side away from the blood collection hole. At this time, due to the cooperation of the elastic shaft and the baffle, the test paper is blocked by the baffle and guided into the inside of the discharge port by the baffle, which has the advantage of automatic replacement of the test paper;
[0022] Step 6: The waste thrown out from the discharge hole and the discharge port is collected through the cooperation between the recovery box and the connecting pipe, and disinfected by a disinfection lamp to prevent the waste from polluting the use environment, and then the waste inside the recovery box is conveniently cleaned by the user through the material taking door.
[0023] Compared with the prior art, the beneficial effects of the present invention are: the painless and minimally invasive blood sugar testing device;
[0024] 1. Through the cooperation between the set limit sleeve and the first placement groove, it is convenient for the user to insert the finger into the inside of the finger sleeve mechanism. During the insertion process, the first distance sensor detects the progress of the finger entering, thereby triggering the anesthesia spray head to spray anesthesia spray on the finger, thereby reducing the pain during blood collection. Then, the second distance sensor detects the progress of the finger entering again, thereby triggering the operation of the pneumatic belt, and the pneumatic belt presses the user's fingertip tightly against the top of the blood collection hole;
[0025] 2. The installed cylinder is used to drive the installation shaft to move toward the blood collection hole. During the displacement process, the blood collection needle mechanism inside the needle storage box is pushed into the interior of the installation sleeve by the pushing convex. At this time, the blood collection needle mechanism is fixed inside the second placement groove through the cooperation between the first installation piece, the first spring, the first hook and the hook groove. Finally, the blood collection needle mechanism pierces the user's fingertips for blood collection. After the fingertips are pierced, the cylinder is started to drive the installation shaft to move away from the blood collection hole. During this displacement process, the blood collection needle mechanism is driven to move by the first hook. When the blood collection needle mechanism moves to one side of the discharge hole, the blood collection needle mechanism is thrown out from the inside of the discharge hole under the cooperation between the second spring and the second spring. The above steps are repeated to achieve the purpose of automatically replacing the blood collection needle mechanism. The displacement distance of the push rod inside the installation shaft is limited by the cooperation between the second installation pin and the slide groove.
[0026] 3. Under the action of the friction between the second mounting rod and the outer wall of the mounting sleeve, the second mounting rod is pushed toward the inside of the first mounting rod. During the displacement of the second mounting rod toward the inside of the first mounting rod, the cooperation between the second mounting sheet, the second hook and the fourth spring prevents the third spring from pushing the second mounting rod to move upward, so that the third spring contracts and accumulates force. When the second hook moves to one side of the unlocking groove, the fourth spring pulls the second hook to rotate toward the outside of the first mounting rod, so that the second hook and the first mounting rod are unlocked, and then the third spring drives the second mounting rod to rebound quickly upward, so that the blood collection needle mechanism quickly pierces the fingertips of the user, reducing the time for nerve endings to perceive stimulation, thereby alleviating pain.
[0027] 4. The second mounting block is provided to limit the insertion depth. At the same time, the second mounting block is used to quickly hit the fingertips of the user through the force storage mechanism, so that the pre-fragmented piece is broken, and then the second mounting block and the needle are pulled into the inside of the needle sleeve under the action of the fifth spring, so as to prevent the blood collection needle mechanism from being reused and prevent the user from being stabbed by the needle when handling the used needle. The rubber pad is used to buffer the impact between the needle sleeve and the second mounting block and the fingertips of the user to reduce pain. The displacement distance of the second mounting rod inside the first mounting rod is limited by the cooperation between the limiting column and the limiting groove;
[0028] 5. The test paper in the paper storage slot is driven to move toward the blood collection hole by the first guide wheel, so that the test paper is inserted into the inside of the connection port and is at the bottom of the blood collection hole, and the blood leaked from the blood collection hole is collected for testing. After the test is completed, the test paper is driven to move to the side away from the blood collection hole by the second guide wheel. At this time, due to the cooperation of the elastic shaft and the baffle, the test paper is blocked by the baffle and guided into the inside of the discharge port by the baffle, which has the advantage of automatic replacement of the test paper;
[0029] 6. The waste thrown out from the discharge hole and the discharge port is collected through the cooperation between the recovery box and the connecting pipe, and is disinfected by a disinfection lamp to prevent the waste from polluting the use environment. The waste inside the recovery box is then cleaned by the user through the material taking door. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The specific implementation method is as follows: the cylinder 202 drives the mounting shaft 203 to move toward the blood collection hole 103. During the displacement process, the blood collection needle mechanism 5 inside the needle storage box 3 is pushed into the interior of the mounting sleeve 201 through the pushing protrusion 204. At this time, the blood collection needle mechanism 5 is fixed inside the second placement groove 205 through the cooperation between the first mounting piece 207, the first spring 208, the first hook 209, and the hook groove 507. Finally, the blood collection needle mechanism 5 pierces the user's fingertips for blood collection. After piercing the fingertips, the cylinder 202 is started to drive the mounting shaft 203 to move to the side away from the blood collection hole 103. During this displacement process, the blood collection needle mechanism 5 is driven to move by the first hook 209. When the blood collection needle mechanism 5 moves to one side of the discharge hole 214, the blood collection needle mechanism 5 is thrown out from the inside of the discharge hole 214 under the cooperation between the second spring 210 and the second spring 210. The above steps are repeated to complete the purpose of automatically replacing the blood collection needle mechanism 5. Through the cooperation between the second mounting pin 212 and the slide groove 213 The third spring 403 is used to limit the displacement distance of the push rod 211 inside the installation shaft 203. When the installation shaft 203 moves toward the top of the installation sleeve 201, the second installation rod 402 is pushed into the first installation rod 401 by the friction between the second installation rod 402 and the outer wall of the installation sleeve 201. During the displacement of the second installation rod 402 into the first installation rod 401, the third spring 403 is prevented from pushing the second installation rod 402 into the first installation rod 401 through the cooperation between the second installation sheet 404, the second hook 405, and the fourth spring 406. The second mounting rod 402 moves upward, causing the third spring 403 to contract and accumulate force. When the second hook 405 moves to one side of the unlocking slot 409, the fourth spring 406 pulls the second hook 405 to rotate toward the outside of the first mounting rod 401, causing the second hook 405 and the first mounting rod 401 to unlock. Then the third spring 403 drives the second mounting rod 402 to rebound upward quickly, allowing the blood collection needle mechanism 5 to quickly penetrate the user's fingertips, reducing the time for nerve endings to perceive stimulation, thereby alleviating pain.
[0042] See also Figure 1-5The present invention provides a technical solution: a painless minimally invasive blood glucose testing device, wherein a pre-cut piece 502 is fixedly installed on the top of a needle sleeve 501, a second mounting block 503 is fixedly installed inside the pre-cut piece 502, a needle 504 is fixedly installed on the top of the second mounting block 503, the top of the second mounting block 503 is higher than the top of the needle sleeve 501, a fifth spring 505 is fixedly connected to the bottom of the second mounting block 503, the fifth spring 505 is fixedly installed inside the needle sleeve 501, and a rubber pad 504 is fixedly installed on the top of the needle sleeve 501 and the second mounting block 503. 6.

[0043] The specific implementation method is as follows: through the cooperation between the limiting sleeve 104 and the first placement groove 102, it is convenient for the user to insert the finger into the interior of the finger sleeve mechanism 1. During the insertion process, the first distance sensor 105 detects the progress of the finger entry, thereby triggering the anesthesia nozzle 106 to spray anesthetic spray on the finger, thereby reducing the pain during blood collection. Then, the second distance sensor 107 detects the progress of the finger entry again, thereby triggering the operation of the pneumatic belt 108. The pneumatic belt 108 presses the user's fingertip against the top of the blood collection hole 103. When the second hook 405 pierces the user's fingertip, the second mounting block 503 limits the insertion depth. At the same time, when the second mounting block 503 quickly hits the user's fingertips through the force storage mechanism 4, the pre-break piece 502 is broken, and then the second mounting block 503 and the needle 504 are pulled into the interior of the needle sleeve 501 under the action of the fifth spring 505, preventing the blood collection needle mechanism 5 from being reused and preventing the user from being stabbed by the needle 504 when handling the used needle 504.

During the displacement process, the blood collection needle mechanism 5 in the needle storage box 3 is pushed into the interior of the installation sleeve 201 through the pushing protrusion 204. At this time, the blood collection needle mechanism 5 is fixed in the interior of the second placement groove 205 through the cooperation between the first installation piece 207, the first spring 208, the first hook 209, and the hook groove 507. Finally, the blood collection needle mechanism 5 pierces the user's fingertips for blood collection. After the fingertips are pierced, the cylinder 202 is started to drive the installation shaft 203 to move toward The blood collection needle mechanism 5 is displaced away from the side of the blood collection hole 103. During this displacement process, the first hook 209 drives the blood collection needle mechanism 5 to move. When the blood collection needle mechanism 5 moves to one side of the discharge hole 214, the blood collection needle mechanism 5 is thrown out from the inside of the discharge hole 214 under the cooperation between the second spring 210 and the second spring 210. The purpose of automatically replacing the blood collection needle mechanism 5 can be achieved by repeating the above steps. The displacement distance of the push rod 211 inside the installation shaft 203 is limited by the cooperation between the second installation pin 212 and the slide groove 213.
[0048] When the mounting shaft 203 moves toward the top of the mounting sleeve 201, the second mounting rod 402 is pushed toward the inside of the first mounting rod 401 under the action of the friction force between the second mounting rod 402 and the outer wall of the mounting sleeve 201. During the displacement of the second mounting rod 402 toward the inside of the first mounting rod 401, the third spring 403 is prevented from pushing the second mounting rod 402 to move upward by the cooperation between the second mounting piece 404, the second hook 405, and the fourth spring 406, so that the third spring 403 contracts and accumulates force. When the second hook 405 moves to one side of the unlocking groove 409, the fourth spring 406 pulls the second hook 405 to rotate toward the outside of the first mounting rod 401, so that the second hook 405 and the first mounting rod 401 are unlocked, and then the third spring 403 drives the second mounting rod 402 to rebound rapidly upward, so that the blood collection needle mechanism 5 quickly penetrates the fingertips of the user, reducing the perception time of the nerve endings to the stimulation, thereby alleviating the pain.
[0049] When the second hook 405 pierces the user's fingertip, the second mounting block 503 limits the piercing depth. At the same time, the second mounting block 503 is made to quickly hit the user's fingertip through the force storage mechanism 4, so that the pre-broken piece 502 is broken, and then the second mounting block 503 and the needle 504 are pulled into the needle sleeve 501 under the action of the fifth spring 505, so as to prevent the blood collection needle mechanism 5 from being reused and prevent the user from being pierced by the needle 504 when handling the used needle 504. The rubber pad 506 is used to buffer the impact between the needle sleeve 501 and the second mounting block 503 and the user's fingertip to reduce pain. The displacement distance of the second mounting rod 402 inside the first mounting rod 401 is limited by the cooperation between the limiting column 407 and the limiting groove 408;
[0050] After the puncture is completed, the first guide wheel 603 drives the test paper 609 in the paper storage slot 602 to move toward the blood sampling hole 103, so that the test paper 609 is inserted into the connection port 604 and is at the bottom of the blood sampling hole 103, and the blood leaked from the blood sampling hole 103 is collected for testing. After the test is completed, the second guide wheel 605 drives the test paper 609 to move to the side away from the blood sampling hole 103. At this time, due to the cooperation of the elastic shaft 606 and the baffle 607, the test paper 609 is blocked by the baffle 607 and guided into the inside of the discharge port 608 by the baffle 607, which has the advantage of automatically replacing the test paper 609.
[0051] The waste thrown out from the discharge hole 214 and the discharge port 608 is collected through the cooperation between the recovery box 701 and the connecting pipe 702, and is disinfected by the disinfection lamp 703 to prevent the waste from polluting the use environment. The waste inside the recovery box 701 is then cleaned by the user through the material collection door 704.

10. A method for using a painless minimally invasive blood sugar testing device, used for a painless minimally invasive blood sugar testing device according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Through the cooperation between the limiting sleeve (104) and the first placement groove (102), it is convenient for the user to insert the finger into the interior of the finger sleeve mechanism (1). During the insertion process, the first distance sensor (105) detects the progress of the finger entering, thereby triggering the anesthesia spray head (106) to spray anesthesia spray on the finger, thereby reducing the pain during blood collection. Then, the second distance sensor (107) detects the progress of the finger entering again, thereby triggering the operation of the pneumatic belt (108), and the pneumatic belt (108) presses the user's fingertip tightly against the top of the blood collection hole (103); Step 2: The cylinder (202) drives the installation shaft (203) to move toward the blood collection hole (103). During the displacement process, the blood collection needle mechanism (5) inside the needle storage box (3) is pushed into the interior of the installation sleeve (201) through the pushing protrusion (204). At this time, the blood collection needle mechanism (5) is fixed inside the second placement groove (205) through the cooperation between the first installation piece (207), the first spring (208), the first hook (209), and the hook groove (507). Finally, the blood collection needle mechanism (5) pierces the user's fingertips to collect blood. After the fingertips are pierced, the cylinder (202) is started to drive the installation shaft (203) to move. 03) is displaced to a side away from the blood collection hole (103), and during this displacement process, the blood collection needle mechanism (5) is driven to displace by the first hook (209). When the blood collection needle mechanism (5) is displaced to one side of the discharge hole (214), the blood collection needle mechanism (5) is thrown out from the inside of the discharge hole (214) under the cooperation between the second spring (210) and the second spring (210). The above steps are repeated to achieve the purpose of automatically replacing the blood collection needle mechanism (5). The displacement distance of the push rod (211) inside the mounting shaft (203) is limited by the cooperation between the second mounting pin (212) and the slide groove (213); Step 3: When the installation shaft (203) moves toward the top of the installation sleeve (201), the second installation rod (402) is pushed toward the inside of the first installation rod (401) under the action of the friction force between the second installation rod (402) and the outer wall of the installation sleeve (201). During the process of the second installation rod (402) moving toward the inside of the first installation rod (401), the cooperation between the second installation sheet (404), the second hook (405) and the fourth spring (406) prevents the third spring (403) from pushing the second installation rod (402) toward the inside of the first installation rod (401). The second hook (405) is displaced upward, causing the third spring (403) to contract and accumulate force. When the second hook (405) is displaced to one side of the unlocking slot (409), the fourth spring (406) pulls the second hook (405) to rotate toward the outside of the first mounting rod (401), causing the second hook (405) and the first mounting rod (401) to unlock. Then, the third spring (403) drives the second mounting rod (402) to rebound upward quickly, causing the blood collection needle mechanism (5) to quickly penetrate the fingertips of the user, thereby reducing the time for the nerve endings to perceive the stimulation, thereby alleviating the pain. Step 4: When the second hook (405) pierces the fingertips of the user, the second mounting block (503) limits the piercing depth, and at the same time, the second mounting block (503) is made to quickly hit the fingertips of the user through the force storage mechanism (4), so that the pre-broken piece (502) is broken, and then the second mounting block (503) and the needle (504) are pulled into the interior of the needle sleeve (501) under the action of the fifth spring (505), so as to prevent the blood collection needle mechanism (5) from being reused and prevent the user from being pierced by the needle (504) when handling the used needle (504). The rubber pad (506) is used to buffer the impact between the needle sleeve (501) and the second mounting block (503) and the fingertips of the user to reduce pain, and the displacement distance of the second mounting rod (402) inside the first mounting rod (401) is limited by the cooperation between the limiting column (407) and the limiting groove (408); Step 5: After the puncturing is completed, the first guide wheel (603) drives the test paper (609) in the paper storage slot (602) to move toward the blood sampling hole (103), so that the test paper (609) is inserted into the connection port (604) and is located at the bottom of the blood sampling hole (103), and the blood leaked from the blood sampling hole (103) is collected for testing. After the test is completed, the second guide wheel (605) drives the test paper (609) to move to the side away from the blood sampling hole (103). At this time, due to the cooperation of the elastic shaft (606) and the baffle (607), the test paper (609) is blocked by the baffle (607) and guided into the inside of the discharge port (608) by the baffle (607), which has the advantage of automatically replacing the test paper (609); Step 6: The waste thrown out from the discharge hole (214) and the discharge port (608) is collected by the cooperation between the recovery box (701) and the connecting pipe (702), and is disinfected by the disinfection lamp (703) to prevent the waste from polluting the use environment, and then the waste inside the recovery box (701) is conveniently cleaned by the user through the material taking door (704).
