Description

Technical Field

[0001] This invention belongs to the field of blood glucose monitoring technology, specifically relating to a blood glucose monitor and monitoring method based on painless dynamic monitoring of patients' blood glucose using saliva. Background Technology

[0002] A saliva glucose monitor detects a patient's blood sugar level by collecting saliva. It uses a bio-enzyme embedded in a transistor to detect glucose, and the transistor transmits the presence of glucose, thus achieving the function of blood sugar detection.

[0003] Currently, most existing salivary blood glucose monitors use disposable collection devices for saliva collection. This means that when traveling, multiple collection devices need to be carried along with the monitor, affecting its portability. Furthermore, the collected saliva needs to be spat into an external collector, then a calibrated instrument is used to extract a quantitative amount of saliva, and finally dripped into the testing instrument for calculation. During this process, the saliva sample is easily contaminated by the external environment when placed outside the body, thus affecting the monitoring results. To address this, we propose a blood glucose monitor based on painless dynamic saliva monitoring. Summary of the Invention

[0004] The purpose of this invention is to provide a blood glucose monitor based on painless dynamic monitoring of saliva to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a blood glucose monitor based on painless dynamic monitoring of saliva, comprising a monitor body, a saliva tube, and a cleaning tank. The top of the monitor body has a monitoring slot, and inside the monitoring slot is a biosensor connected to the monitor body via a data cable. A conical needle is fixedly installed at the end of the biosensor. The monitoring slot contains a saliva tube, and one end of the saliva tube has a sampling tube at its top. The sampling tube has a segmented structure, and the top of the sampling tube is connected by a plug-in method using friction. The end of the saliva tube near the sampling tube has a threaded plug, and the inner side of the plug has a rubber sealing layer. The plug and the saliva tube are sealed together by the rubber sealing layer. The end of the saliva tube away from the plug has a piston inside, and a push rod is provided on one side of the piston.

[0006] The working principle of the above technical solution is as follows:

[0007] In use, remove the saliva tube, spit saliva into it using the sampling tube, and simultaneously pull the push rod to move the piston towards the end of the saliva tube furthest from the sampling tube, ensuring stable saliva intake. After collecting a certain amount of saliva, insert the saliva tube into the monitoring chamber. Use the conical needle at the end of the biosensor to pierce the rubber seal between the plug and the saliva tube, allowing the biosensor to be stably inserted into the saliva tube to monitor the saliva inside. Connect the biosensor to the monitor via a data cable for data transmission. The monitor analyzes and processes the data, and finally displays the monitoring results on the screen, thus completing the blood glucose test. Then, the system automatically adjusts the insulin pump speed based on dynamic blood glucose levels to deliver an appropriate amount of insulin to the patient.

[0008] Preferably, a cleaning tank is provided at the opposite end of the monitoring instrument body, a cleaning needle is movably provided inside the cleaning tank, a plurality of liquid outlet holes are provided on the outer peripheral surface of the cleaning needle, a telescopic hose is provided at one end of the cleaning needle, the telescopic hose is sealed and connected to the cleaning needle, a cleaning liquid tank is provided at the bottom of the monitoring instrument body near one end of the cleaning tank, a miniature water pump is provided inside the cleaning liquid tank, and the water outlet of the miniature water pump is sealed and connected to the other end of the telescopic hose through a conduit.

[0009] The saliva tube after testing is inserted into the cleaning tank. A cleaning needle is then inserted into the saliva tube, and a micro water pump is used to draw cleaning solution from the cleaning solution tank. The solution is then injected into the cleaning needle through a telescopic hose. Several outlet holes on the outer periphery of the cleaning needle are used to flush the inside of the saliva tube, causing the cleaning solution and saliva mixture inside the saliva tube to be discharged from the sampling tube, thereby achieving the purpose of cleaning.

[0010] Preferably, a movable block is fitted around the connection between the cleaning needle and the telescopic hose. A threaded block is provided on the top of the movable block, and a screw is provided on the inner side of the threaded block. The screw is helically connected to the threaded block, and a micro motor is fixedly installed at one end of the screw. The output shaft end of the micro motor is fixedly connected to the screw.

[0011] By using a micro motor to drive the screw to rotate, which in turn drives the threaded block to move, thereby sliding the moving block together to extend the cleaning needle into the cleaning tank so that it can be inserted into the saliva tube to rinse its inner wall.

[0012] Preferably, both the top of the monitoring tank and the bottom of the cleaning tank are provided with notches, and the opening size of the notches is the same as the diameter of the sampling tube.

[0013] The notches allow the saliva tube to move easily within the monitoring and cleaning tanks. By reversing the notches on the monitoring and cleaning tanks, saliva can be prevented from flowing out of the sampling tube during monitoring and the mixture of cleaning solution and saliva can be easily discharged during cleaning.

[0014] Preferably, the inner wall of one end of the cleaning tank and the monitoring tank is provided with a magnetic ring. The magnetic ring is embedded in one end of the cleaning tank and the monitoring tank respectively by means of embedding. The outer end of the plug is provided with a metal ring, which is fixedly embedded in the outer end of the plug.

[0015] By installing magnetic rings inside both the cleaning tank and the monitoring tank, along with the metal ring at the outer end of the plug, the stability of the saliva tube within the cleaning tank and the monitoring tank is ensured, preventing accidental drops.

[0016] Preferably, the saliva tube has protrusions on both sides of the outer periphery of the end away from the plug, and the protrusions are fixedly installed on both sides of one end of the saliva tube.

[0017] By setting a protrusion on the outside of the saliva tube, it is easier to remove the saliva tube from inside the cleaning tank or monitoring tank, thus saving effort.

[0018] Preferably, the movable block is provided with limiting blocks on both sides, and the limiting blocks extend into the housing of one end of the cleaning tank and are slidably connected thereto.

[0019] The limiting block ensures the stability of the moving block during movement and prevents deviation of the moving block, which could cause the cleaning needle to tilt when it pierces the saliva tube.

[0020] Preferably, a display screen is provided on one side surface of the monitoring instrument body, and the display screen is fixedly installed on one side of the monitoring instrument body by embedding.

[0021] The monitoring data results are displayed on a dedicated screen to facilitate user retrieval of the data.

[0022] Preferably, the monitoring instrument body has a control panel at the bottom of the side with the display screen, and the control panel is fixedly installed to the side of the monitoring instrument body by embedding.

[0023] By setting up the control panel, the device can be controlled, allowing the monitoring instrument to be operated as needed.

[0024] This invention also provides a method for monitoring blood glucose in patients based on painless dynamic saliva monitoring. The method is as follows: In the initial state, the saliva tube is inserted into the cleaning tank and is attracted by the magnetic ring inside the cleaning tank and the metal ring at the outer end of the plug. In use, the saliva tube is removed from the cleaning tank by pinching the protrusion, and then saliva is spat into the sampling tube. At the same time, the push rod is pulled outward, which generates suction inside the saliva tube, drawing a certain amount of saliva into the saliva tube. Then, the saliva tube is inserted into the monitoring tank. The conical needle at the end of the biosensor pierces the rubber sealing layer, allowing the biosensor to enter the inside of the saliva tube to monitor the saliva inside. The monitoring data is transmitted to the monitoring instrument through a wire, analyzed and processed, and finally displayed on the display screen.

[0025] After the test is completed, the saliva tube is removed from the monitoring tank and inserted into the cleaning tank. Then, the control panel is operated, and a micro motor, screw, and threaded block are used to drive the moving block to insert the cleaning needle into the saliva tube. Then, a micro water pump is used to draw cleaning solution from the cleaning solution tank and introduce it into the cleaning needle through a telescopic hose to rinse the inside. Because the notch on the cleaning tank is opened downwards, the sampling tube is facing downwards. During the cleaning process, the saliva will be discharged along with the cleaning solution, thus completing the post-monitoring cleaning work for the next use.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By employing the principle of a syringe, a certain suction force is provided when sampling through the sampling tube to improve the convenience of sampling. Combined with a rubber sealing layer and a conical needle at the end of the biosensor, the biosensor is inserted into the saliva tube to achieve the purpose of monitoring. Compared with traditional samplers, it is more convenient and faster, and can avoid saliva spillage. At the same time, it effectively avoids excessive saliva exposure in the external environment, which could cause saliva sample contamination.

[0028] 2. By setting a cleaning tank at one end of the monitor body, the inside of the saliva tube can be rinsed through the cleaning needle in the cleaning tank after use, so that the mixture of saliva and cleaning solution inside can be quickly discharged, ensuring the cleanliness of the saliva tube. This allows the saliva tube to be reused, greatly improving the utilization rate and avoiding the waste of medical resources.

[0029] 3. The blood glucose monitor based on painless saliva dynamic monitoring provided by this invention can be used to analyze the blood glucose content of the patient's saliva after saliva sampling. The entire monitoring process of the monitor can be automated, enabling dynamic and rigorous monitoring of the patient's blood glucose. At the same time, the blood glucose concentration of the patient can be dynamically adjusted according to the patient's blood glucose content to ensure that the blood glucose concentration in the patient's body is in a good state, which is conducive to the patient's recovery and wound healing.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-6This invention provides a technical solution for a blood glucose monitoring device based on painless dynamic monitoring of saliva in patients: it includes a monitoring device body 1, a saliva tube 8, and a cleaning tank 16. The top of the monitoring device body 1 has a monitoring tank 4. Inside the monitoring tank 4 is a biosensor 5 connected to the inside of the monitoring device body 1 via a data cable. A conical needle 6 is fixedly installed at the end of the biosensor 5. Inside the monitoring tank 4 is the saliva tube 8. One end of the saliva tube 8 has a sampling tube 9 at its top. The sampling tube 9 has a segmented structure. The top end of the sampling tube 9 is connected by a plug-in method using friction. The other end of the sampling tube 9 can be fixed to the mouth of a bedridden patient to automatically sample the saliva in the patient's mouth in real time, thereby reducing the labor of medical staff. The saliva tube 8 is provided with a plug 10 connected by threads at one end near the sampling tube 9. The plug 10 is provided with a rubber sealing layer 12 on the inside. The plug 10 and the saliva tube 8 are sealed together by the rubber sealing layer 12. The saliva tube 8 is provided with a piston 14 at the end away from the plug 10. A push rod 15 is provided on one side of the piston 14.

[0039] The working principle of the above technical solution is as follows:

[0040] In use, remove the saliva tube 8, and spit saliva into it using the sampling tube 9. Simultaneously, pull the push rod 15 to move the piston 14 towards the end of the saliva tube 8 away from the sampling tube 9, ensuring stable saliva absorption into the saliva tube 8. After collecting a certain amount of saliva, insert the saliva tube 8 into the monitoring slot 4. Use the conical needle 6 at the end of the biosensor 5 to pierce the rubber sealing layer 12 between the plug 10 and the saliva tube 8, allowing the biosensor 5 to be stably inserted into the saliva tube 8 to monitor the saliva inside. Connect the biosensor 5 to the monitor body 1 via a data cable for data transmission. The monitor body 1 analyzes and processes the data, and finally displays the monitoring results on the display screen 2. These results include patient identification information, blood glucose concentration, required insulin infusion rate, and patient weight information, thus completing the blood glucose test. In this embodiment, the patient's blood glucose can be dynamically monitored at intervals of 10-30 minutes according to actual clinical needs. The speed at which insulin is pumped by a micro-infusion pump is automatically adjusted by dynamic blood glucose levels to deliver an appropriate amount of insulin to the patient's body. (When diabetic patients start insulin therapy, they should always use short-acting insulin. Moreover, the initial dosage should be estimated according to the following method on the basis of relatively stable diet and exercise, and then adjusted according to the monitoring results of the condition.)

[0041] Estimated based on fasting blood glucose:

[0042] Daily insulin dosage (μ) = [fasting blood glucose (mg / dl) - 100] x 10 x body weight (kg) x 0.6 ÷ 1000 ÷ 2

[0043] 100 represents the normal blood glucose level;

[0044] x 10 converts the amount of blood glucose above normal per liter of body fluid;

[0045] x 0.6 represents 60% of total body fluid volume;

[0046] ÷1000 converts blood glucose (mg) to grams;

[0047] ÷2 means 2 grams of blood glucose requires 1 μg of insulin.

[0048] To avoid hypoglycemia, use 1 / 2 to 1 / 3 of the actual amount.

[0049] Based on the insulin dosage calculated above, and combined with the basic parameters of the microinfusion pump, the infusion rate of insulin by the microinfusion pump is calculated to ensure accurate and appropriate dynamic infusion of insulin into the patient's body.

[0050] Preferably, a cleaning tank 16 is provided at the opposite end of the monitoring instrument body 1. A cleaning needle 22 is movably provided inside the cleaning tank 16.

The water outlet of the micro water pump 19 is sealed and connected to the other end of the telescopic hose 20 through a conduit.

[0051] The saliva tube 8 after testing is inserted into the cleaning tank 16. The cleaning needle 22 is inserted into the saliva tube 8. Then, the cleaning solution in the cleaning solution tank 18 is drawn by the micro water pump 19 and injected into the cleaning needle 22 through the telescopic hose 20. The inside of the saliva tube 8 is rinsed by several liquid outlet holes 23 on the outer periphery of the cleaning needle 22, so that the cleaning solution and saliva mixture in the saliva tube 8 are discharged from the sampling tube 9, thereby achieving the purpose of cleaning.

[0052] Preferably, a movable block 21 is provided around the connection between the cleaning needle 22 and the telescopic hose 20. A threaded block 25 is provided on the top of the movable block 21.

The output shaft end of the micro motor 27 is fixedly connected to the screw 26.

[0053] By using a micro motor 27 to drive the screw 26 to rotate, it causes the threaded block 25 to move, thereby sliding the moving block 21 together, extending the cleaning needle 22 into the interior of the cleaning tank 16 so that it can be inserted into the saliva tube 8 to rinse its inner wall.

[0054] Preferably, both the top of the monitoring tank 4 and the bottom of the cleaning tank 16 are provided with notches 17, and the opening size of the notches 17 is the same as the diameter of the sampling tube 9.

[0055] The notch 17 facilitates the movement of the saliva tube 8 within the monitoring tank 4 and the cleaning tank 16. By reversing the notches 17 on the monitoring tank 4 and the cleaning tank 16, saliva is prevented from flowing out of the sampling tube 9 during monitoring and the mixture of cleaning solution and saliva is facilitated to flow out during cleaning.

[0056] Preferably, magnetic rings 7 are provided on the inner walls of one end of the cleaning tank 16 and the monitoring tank 4. The magnetic rings 7 are respectively embedded in the inner end of the cleaning tank 16 and the monitoring tank 4 by means of embedding. A metal ring 11 is provided on the outer end of the plug 10. The metal ring 11 is fixedly embedded in the outer end of the plug 10.

[0057] By installing magnetic rings 7 inside both the cleaning tank 16 and the monitoring tank 4, and in conjunction with the metal ring 11 at the outer end of the plug 10, the stability of the saliva tube 8 within the cleaning tank 16 and the monitoring tank 4 is ensured, preventing accidental drop.

[0058] Preferably, protrusions 13 are provided on both sides of the outer periphery of the end of the saliva tube 8 away from the plug 10, and the protrusions 13 are fixedly installed on both sides of one end of the saliva tube 8.

[0060] Preferably, the movable block 21 is provided with limiting blocks 24 on both sides, and the limiting blocks 24 extend into the housing of one end of the cleaning tank 16 and are slidably connected thereto.

[0061] The limiting block 24 ensures the stability of the moving block 21 during movement and prevents deviation of the moving block 21, which could cause the cleaning needle 22 to tilt when it is inserted into the saliva tube 8.

[0062] Preferably, a display screen 2 is provided on one side surface of the monitoring instrument body 1, and the display screen 2 is fixedly installed on one side of the monitoring instrument body 1 by embedding.

[0066] Example 2

[0067] This embodiment provides a method for monitoring blood glucose in patients based on painless dynamic saliva monitoring. The method is as follows: In the initial state, the saliva tube 8 is inserted into the cleaning tank 16 and is attracted by the magnetic ring 7 inside the cleaning tank 16 and the metal ring 11 at the outer end of the plug 10. In use, the saliva tube 8 is taken out from the cleaning tank 16 by pinching the protrusion 13, and then saliva is spat into the sampling tube 9. At the same time, the push rod 15 is pulled outward, so that the inside of the saliva tube 8 is suctioned, and a certain amount of saliva is sucked into the inside of the saliva tube 8. Then, the saliva tube 8 is inserted into the monitoring tank 4. The conical needle 6 at the end of the biosensor 5 pierces the rubber sealing layer 12, so that the biosensor 5 enters the inside of the saliva tube 8 to monitor the saliva inside. The monitoring data is transmitted to the monitoring instrument body 1 through the wire, analyzed and processed, and finally displayed on the display screen 2.

[0068] After the test is completed, the saliva tube 8 is removed from the monitoring tank 4 and inserted into the cleaning tank 16. Then, the control panel 3 is operated to drive the moving block 21 to move using the micro motor 27 in conjunction with the screw 26 and threaded block 25, so that the cleaning needle 22 is inserted into the saliva tube 8. Then, the cleaning solution in the cleaning solution tank 18 is drawn out by the micro water pump 19 and introduced into the cleaning needle 22 through the telescopic hose 20 to rinse the inside. Since the notch 17 on the cleaning tank 16 is opened downwards, the sampling tube 9 is facing downwards. During the cleaning process, the saliva will be discharged along with the cleaning solution, thus completing the cleaning work after monitoring for the next use.
