[0032] As Figures 1-8 shown:

[0033] An integrated injection device for on-line monitoring of blood glucose and intelligent calculation of insulin injection dose, including an outer shell base 101. An internal telescopic pump 102 is fixedly installed in the outer shell base 101 through a provided installation cavity, and a controller for controlling the telescopic pump 102 is installed inside the outer shell base 101;

[0034] The output end of the telescopic pump 102 is fixedly installed with a push plate 103. A medicine storage cylinder 104 is placed on one side of the outer shell base 101 through a provided card interface. A first piston disk 105 slides inside the medicine storage cylinder 104, and one end of the first piston disk 105 is fixedly installed with a piston rod 106;

[0035] On one side of the outer shell base 101, there is a shell 108. Inside the shell 108, there is a fixed mounting plate 109. On the mounting plate 109, there is a fixed monitoring and control module 110.

At the center of the mounting plate 109, there is a plug connector 112 fixed through a drilled mounting hole. One end of the plug connector 112 is fixedly connected to a probe 111. Between the outer shell base 101 and the shell 108, there is a connecting hose 107. The two ends of the connecting hose 107 are respectively inserted into one end of the medicine storage cylinder 104 and the plug connector 112. Inside the shell 108, there is a fixed blocking plate 113;

[0036] On the outer shell base 101, there is a clamping structure 2 for clamping and locking the medicine storage cylinder 104. The clamping structure 2 includes a rectangular groove opened on the other side of the outer shell base 101. And inside the rectangular groove, there is a pressing plate 201. On one side of the pressing plate 201, there are symmetrically arranged ejector rods 203. Between the pressing plate 201 and the outer shell base 101, there are symmetrically arranged first springs 202;

[0037] On one side of the ejector rod 203, there is an L-shaped clamping plate 204. Between the L-shaped clamping plate 204 and the outer shell base 101, there are symmetrically arranged first telescopic rods 206. On the surface of the first telescopic rods 206, there is a second spring 205 wound around. The two ends of the second spring 205 are respectively fixedly connected to the outer shell base 101 and the L-shaped clamping plate 204. Inside the outer shell base 101, there is an activity cavity opened. The L-shaped clamping plate 204 can move up and down in the activity cavity opened in the outer shell base 101. On the surface of the medicine storage cylinder 104, there is a card slot 207 adapted to the L-shaped clamping plate 204. The L-shaped clamping plate 204 can be stuck in the card slot 207 opened on the medicine storage cylinder 104 for connecting and locking the medicine storage cylinder 104 and the outer shell base 101. On the sides of the ejector rod 203 and the L-shaped clamping plate 204 close to each other, there are first inclined surfaces;

[0038] Near the position of the medicine storage cylinder 104 inside the outer shell base 101, there are symmetrically arranged arc-shaped grooves opened. And inside the rectangular groove, there are multiple groups of balls 208. The multiple groups of balls 208 can roll in the arc-shaped grooves opened in the outer shell base 101, and the balls 208 are in contact with the surface of the medicine storage cylinder 104;

[0039] The piston rod 106 is provided with a pressurizing auxiliary mechanism 3, which includes a chamber opened inside the piston rod 106, a second piston disc 301 arranged in the chamber, and a square rod 302 fixed to one side of the second piston disc 301, a circular disc is fixed to the other end of the square rod 302, a circular hole connected to the chamber is opened at the center of the first piston disc 105, a one-way exhaust valve 309 is fixedly installed in the circular hole of the first piston disc 105, and an extrusion sheet 303 is arranged on the upper and lower sides of the square rod 302, and the extrusion sheet 303 and the square rod 302 are provided with a pressurizing auxiliary mechanism 303. A second telescopic rod 306 arranged symmetrically is fixed between the rods 302, a third spring 305 is wound around the surface of the second telescopic rod 306, two ends of the third spring 305 are respectively fixedly connected to the extrusion sheet 303 and the square rod 302, a strip baffle 304 is fixed on the side away from each other of the two groups of extrusion sheets 303, a sliding hole 307 is provided at one end of the piston rod 106, a resistance block 308 corresponding to the extrusion sheet 303 is fixed inside the drug storage cartridge 104, and one end of the resistance block 308 and one end of the extrusion sheet 303 are both provided with a second inclined surface;

[0040] A strip groove is formed on the surface of the square rod 302 , and a limit block is fixedly installed on the inner side wall of the piston rod 106 . The limit block can slide in the strip groove formed on the square rod 302 to limit the movement of the square rod 302 .

[0041] In this embodiment, when the integrated injection device for online monitoring of blood sugar and intelligent calculation of insulin injection dosage is used, the pressing plate 201 is first pressed to compress the first spring 202, and the two sets of ejector rods 203 are simultaneously pressed, such as Figure 5 As shown, the ends of the push rod 203 and the L-shaped card plate 204 close to each other are both provided with a first inclined surface. When the push rod 203 moves, its first inclined surface contacts and fits with the first inclined surface of the L-shaped card plate 204, so that the two groups of L-shaped card plates 204 move in the direction away from each other. The L-shaped card plate 204 is connected to the drug storage cartridge 104 through the second spring 205 and the first telescopic rod 206. This arrangement can limit and stabilize the connection of the L-shaped card plate 204. The two groups of L-shaped card plates 204 move in opposite directions, thereby compressing the second spring 205 and the first telescopic rod 206 until the L-shaped card plate 204 is disengaged from the card slot 207 of the drug storage cartridge 104, thereby releasing the connection and lock between the drug storage cartridge 104 and the housing seat 101;

[0042] Subsequently, the medicine storage cylinder 104 can be removed from the outer shell base 101. Then, one end of the medicine storage cylinder 104 is inserted into the insulin reagent port. By pulling the piston rod 106, the first piston disk 105 is driven to move, and the solution of the insulin reagent (not shown in the figure) is drawn into the interior of the medicine storage cylinder 104 until one side of the first piston disk 105 contacts the abutting block 308. Through the setting of the abutting block 308, the first piston disk 105 can be limited in position, preventing the first piston disk 105 from detaching from the medicine storage cylinder 104. The medicine storage cylinder 104 can be used for cyclic loading, can be assembled with insulin reagent solutions of different specifications, such as long-acting reagents or short-acting reagents, and can be flexibly assembled with medicines according to actual usage requirements, improving the usage effect of the device;

[0043] Subsequently, the pressing plate 201 is pressed again, thereby driving the two L-shaped clamping plates 204 to move away from each other. Then, the medicine storage cylinder 104 is placed at the clamping interface of the outer shell base 101. Subsequently, the pressing on the pressing plate 201 is released. At this time, the pressing plate 201 drives the ejector rod 203 to release the extrusion on the L-shaped clamping plate 204. The second spring 205 in the compressed state rebounds, driving the L-shaped clamping plate 204 to fit against the surface of the medicine storage cylinder 104. At the same time, the medicine storage cylinder 104 can be rotated, enabling the medicine storage cylinder 104 to rotate within the clamping interface provided on the outer shell base 101. At the same time, a plurality of balls 208 are arranged in the arc-shaped groove provided inside the outer shell base 101. Through the setting of the balls 208, the contact friction between the medicine storage cylinder 104 and the outer shell base 101 can be reduced, improving the smoothness of the rotation of the medicine storage cylinder 104. Until the card slot 207 of the medicine storage cylinder 104 corresponds to the L-shaped clamping plate 204, at this time, the L-shaped clamping plate 204 can be clamped in the card slot 207 provided on the medicine storage cylinder 104 to lock the medicine storage cylinder 104;

[0044] Subsequently, one end of the connecting hose 107 is inserted into one end of the medicine storage cylinder 104, and the other end is plugged into the plug connector 112. Then, the piston rod 106 is pushed, thereby driving the first piston disk 105 to move. Through the movement of the first piston disk 105, the insulin solution inside the medicine storage cylinder 104 can be pushed into the connecting hose 107 and discharged along the plug connector 112 and the probe 111. Stop pushing the piston rod 106. During this process, ensure that the inside of the connecting hose 107 is filled with insulin solution to avoid air generation during injection to the patient;

[0045] Before starting the injection, the probe 111 and the puncture needle are inserted into the designated position of the patient. The release paper (not shown in the figure) on the bottom surface of the housing 108 contacts the skin, fixing the housing 108 on the skin. Then, the puncture needle is pulled out, leaving the probe 111 to monitor blood glucose;

[0046] The monitoring and control module 110 includes a sensor interface, a signal processor, a central processing unit, an alarm, a communication interface, and a storage battery. The sensor interface is used to receive the electrical signals transmitted by the probe 111. The signal processor converts these analog signals into digital signals. The central processing unit is responsible for executing algorithms, processing data, controlling device operations, and communicating with external devices.

[0047] When the blood glucose level exceeds the preset safe range, the monitoring and control module 110 triggers the alarm to remind the user through sound, vibration, or visual signals. When the blood glucose concentration exceeds the high threshold, the probe 111 sends a signal to the controller of the telescopic pump 102 through the communication interface. The controller activates the telescopic pump 102 to push the push plate 103 to move, thereby driving the piston rod 106 and the first piston disc 105 to move. The probe 111 calculates the required insulin dose based on the blood glucose reading and the preset insulin infusion plan. The telescopic pump 102 drives the piston rod 106 and the first piston disc 105 to move synchronously, applying pressure to the solution in the medicine storage cylinder 104. The insulin solution is discharged through the connecting hose 107, along the plug 112 and the probe 111, and a certain amount of insulin solution is pushed into the patient's body.

[0048] This solution realizes the real-time monitoring of blood glucose levels and the automatic adjustment of insulin injection through real-time blood glucose monitoring and insulin injection functions, greatly reducing the operation steps of patients, improving the convenience and efficiency of treatment. Real-time monitoring can promptly detect abnormal blood glucose levels and automatically issue warnings through the system's preset thresholds to avoid serious hypoglycemia or hyperglycemia events. The design of the integrated machine for blood glucose monitoring and insulin injection improves the usage effect of this device and meets the actual usage requirements.

[0049] When the telescopic pump 102 drives the push plate 103 to move, the push plate 103 drives the square rod 302 to move. Both sides of the square rod 302 are connected to the extrusion piece 303 through the third spring 305 and the second telescopic rod 306. One side of the extrusion piece 303, the strip-shaped baffle 304, abuts against one end of the piston rod 106. When the square rod 302 is pushed, the piston rod 106 and the first piston disc 105 move synchronously. The telescopic pump 102 quantitatively injects the insulin inside the medicine storage cylinder 104 into the connecting hose 107 and discharges it into the patient's body.

[0050] When the first piston disc 105 moves to one end of the medicine storage cartridge 104, the insulin solution in the medicine storage cartridge 104 is emptied, and the extrusion sheet 303 contacts the resistance block 308. A second inclined surface is provided on the side of the resistance block 308 and the extrusion sheet 303 that are close to each other. The resistance block 308 applies pressure to the extrusion sheet 303 to make it slide in the sliding hole 307. The strip baffle 304 corresponds to the sliding hole 307, and the obstruction of the strip baffle 304 is released, so that both the extrusion sheet 303 and the strip baffle 304 can slide in the sliding hole 307. When the telescopic pump 102 drives the push plate 103 to squeeze the square rod 302 again, the square rod 302 drives the second piston disc 301 to move in the piston rod 106. As the second piston disc 301 moves, the piston rod 106 is pressurized, and the pressurized gas is discharged into the connecting hose 107 through the one-way exhaust valve 309, thereby discharging the insulin solution remaining in the connecting hose 107. Through this operation, the insulin solution remaining in the connecting hose 107 can be discharged, and when replacing insulin of different specifications, the insulin solution remaining in the connecting hose 107 can be discharged more cleanly.

[0051] Going further;

[0052] In an optional embodiment, a buffer mechanism 4 is installed on the shell 108, and the buffer mechanism 4 includes a cover 401 arranged at the opening of the shell 108 and an annular plate 402 arranged inside the cover 401, and the surface of the annular plate 402 is fixed with symmetrically arranged connecting blocks 403, and the inner wall of the cover 401 is provided with a limiting groove 404 adapted to the connecting block 403, and the connecting block 403 can slide up and down in the limiting groove 404 provided in the cover 401, and the edge surface of the shell 108 is provided with thread teeth, and the inner wall of the annular plate 402 is provided with a thread groove adapted to the thread teeth, and the upper surface of the sealing plate 113 is fixed with symmetrically arranged fourth springs 405, and the upper surface of the cover 401 is provided with a limiting snap-in 406, and one side of the outer shell seat 101 is provided with an anti-slip opening, and the limiting snap-in 406 is designed in an L-shaped structure, wherein the side opening of the limiting snap-in 406 is larger than the top opening.

[0053] In this embodiment: the buffer mechanism 4 is set so that the annular sheet 402 can be screwed on the shell 108 for connection and locking. When the cover 401 is touched by the outside, the cover 401 can slide on the two groups of connecting blocks 403 set on the annular sheet 402, and the two groups of fourth springs 405 are used to support the cover 401. When the cover 401 is touched, it will move and squeeze the fourth spring 405. The fourth spring 405 has a buffering effect on the squeezing of the cover 401, reducing the impact force of the cover 401 on the shell 108, thereby reducing the sliding of the shell 108 and the shaking of the probe 111 on the skin surface, reducing the pain of the patient;

[0054] Meanwhile, a limiting bayonet 406 is provided on the upper surface of the cover 401, and an anti-disengagement opening is provided on one side of the housing base 101. The limiting bayonet 406 is designed in an L-shaped structure. Among them, the side opening of the limiting bayonet 406 is larger than the top opening, which is convenient for connecting and installing the connecting hose 107.

[0055] It should be noted that the diameters of both ends of the connecting hose 107 are larger than the middle diameter. When the connecting hose 107 is inserted into the medicine storage cylinder 104 and the plug connector 112 respectively, at this time, the connecting hose 107 is respectively located at the limiting bayonet 406 and an anti-disengagement opening is provided on one side of the housing base 101. The limiting bayonet 406 and the anti-disengagement opening can limit the connecting hose 107 to prevent it from falling off due to pulling.

[0056] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
