Description

Technical Field

[0001] This invention relates to the field of injection device technology, specifically to a GLUT1 glucose injection device for septic cardiomyopathy. Background Technology

[0002] Septic cardiomyopathy (SIC) is an acute cardiac dysfunction syndrome caused by sepsis. Its core manifestation is severe impairment of left ventricular or biventricular systolic / diastolic function, but without a history of heart disease. Cardiac function can be partially or completely restored after sepsis is cured. Septic patients have a 20%-50% higher resting energy expenditure (REE) than normal. As a high-energy-consuming organ, cardiomyocytes have an even higher energy demand under infection stress. GLUT1 glucose provides ATP to cardiomyocytes through glycolysis and aerobic oxidation, enabling rapid energy supply.

[0003] When administering glucose injections, an infusion pump is typically used in conjunction with a syringe to inject a measured amount of glucose solution. Currently, infusion pumps can usually only be equipped with one syringe at a time. After the injection is completed, medical staff need to manually install another syringe in a timely manner, which increases the workload of medical staff and reduces the continuity of glucose solution injections for patients. If multiple infusion pumps are equipped at the same time, the floor space required will be increased.

[0004] Combining the above issues, we find that the existing GLUT1 glucose injection devices on the market are difficult to avoid all of the problems mentioned above when in use. Even if they can be solved, they require the use of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose a GLUT1 glucose injection device for septic cardiomyopathy. Summary of the Invention

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.

[0020] Example 1: Please refer to Figures 1-10This invention provides a technical solution: a GLUT1 glucose injection device for septic cardiomyopathy, comprising a main body 1, the main body 1 comprising a housing 11, a controller 12 fixedly connected to one side of the housing 11, the controller 12 being used to control the overall power supply, two positioning plates 13 fixedly connected to the top of the housing 11, damping shafts 14 fixedly connected to the inner walls of the two positioning plates 13, positioning hooks 15 fixedly connected to the rotating ends of the damping shafts 14, and a transparent cover 16 fixedly connected to one side of the two positioning hooks 15. Through the cooperation of the two positioning plates 13, the damping shafts 14 and the two positioning hooks 15, the transparent cover 16 can be flipped. The damping shafts 14 can temporarily limit the transparent cover 16. Without external force pushing, the transparent cover 16 will not rotate on its own. The transparent cover 16 can seal the inside of the housing 11. A placement groove 17 is provided on the other side of the housing 11, and an automatic switching mechanism 2 is provided in the inner cavity of the placement groove 17. The automatic switching mechanism 2 includes a switching injection cylinder unit 21, which is disposed in the inner cavity of the placement groove 17. The switching injection cylinder unit 21 includes a rotating rod 2101, which is rotatably connected to the inner wall of the placement groove 17. A chuck 2102 is fixedly connected to the surface of the rotating rod 2101. The automatic switching mechanism 2 also includes a micro-control switching unit 22, which is located inside the switching injection unit 21. The micro-control switching unit 22 includes four micro-control modules 2201 located on one side of the chuck 2102. The automatic switching mechanism 2 also includes a syringe clamping unit 23, which is disposed on the inner wall of the housing 11. The syringe clamping unit 23 includes a receiving hole 2301 opened on one side of the housing 11, and a movable frame 2302 is slidably connected to the inner cavity of the receiving hole 2301.

[0021] As a further definition of the automatic switching mechanism 2 of the present invention, four engagement grooves 2103 are equally spaced on the surface of the chuck 2102. The inner cavity of the engagement groove 2103 is in close contact with the injection cylinder 2104. A support plate 2105 is fixedly connected to the outer side of the housing 11. A motor 2106 is fixedly connected to the top of the support plate 2105. The output end of the motor 2106 passes through the housing 11 and is fixedly connected to one end of the rotating rod 2101. The rotating rod 2101 is rotatably connected to the inner wall of the placement groove 17 through a bearing. A connecting plate 2107 is fixedly connected to the inner side of the placement groove 17. A first electric push rod 2108 is fixedly connected to one side of the connecting plate 2107. The telescopic end of the first electric push rod 2108 is fixedly connected to the connecting plate 2107. A compression plate 2109 is fixedly connected to the syringe body 2104, which includes an injection tube 2110 and a piston rod 2111. The piston rod 2111 is slidably connected to the inner wall of the syringe body 2104. One side of the compression plate 2109 contacts one end of the piston rod 2111, and the injection tube 2110 contacts the locking groove 2103. By setting the syringe switching unit 21, multiple syringes 2104 filled with glucose solution can be placed at one time, and the switching of syringes 2104 is realized by the rotation of the motor 2106. This avoids the situation where the patient's glucose solution injection is not continuous due to the medical staff not changing the syringes 2104 in time, thereby reducing the workload of the medical staff.

[0022] Two elastic pieces 2112 are fixedly connected to the inner wall of the locking groove 2103. The two elastic pieces 2112 are arranged opposite to each other, and the surface of the elastic pieces 2112 is in close contact with the surface of the injection tube 2110. Several silicone pieces 2117 are fixedly connected to the inner side of the transparent cover 16. The silicone pieces 2117 are in contact with the top of the housing 11. By setting the elastic pieces 2112, the relative squeezing force of the two elastic pieces 2112 on the surface of the injection tube 2110 can achieve stable positioning of the injection tube 2110, ensuring that the injection cylinder 2104 can be stably positioned in the locking groove 2103. The setting of the silicone pieces 2117 can increase the airtightness between the transparent cover 16 and the housing 11, and the softness of the silicone pieces 2117 can avoid obstructing the flipping of the transparent cover 16.

[0023] A sliding groove 2113 is provided on the inner side of the placement groove 17. A first sliding block 2114 is fixedly connected to one side of the compression plate 2109. A retaining ring 2115 is fixedly connected to the surface of the telescopic end of the first electric push rod 2108. A second sliding block 2116 is fixedly connected to the surface of the retaining ring 2115. The surfaces of the first sliding block 2114 and the second sliding block 2116 are slidably connected to the inner cavity of the sliding groove 2113. By setting the sliding groove 2113, the first sliding block 2114, the retaining ring 2115 and the second sliding block 2116 in cooperation, the first sliding block 2114 and the second sliding block 2116 can be fitted and slid in the sliding groove 2113 to achieve stable guidance of the movement trajectory of the compression plate 2109 and the telescopic end of the first electric push rod 2108, thereby improving the stability when pushing the piston rod 2111.

[0024] The specific implementation of this embodiment is as follows: A patient with sepsis needs to be injected with GLUT1 glucose solution for rapid energy supply. Medical staff simultaneously infuse four syringes 2104 with glucose solution. The syringes 2104 containing the glucose solution are positioned within the chuck 2102. The injection tube 2110 is inserted into the locking groove 2103. As the injection tube 2110 moves into the locking groove 2103, two elastic plates 2112 are compressed and deformed until the injection tube 2110 is completely locked into the locking groove 2103. The reaction force of the elastic plates 2112 increases the pressure on the injection tube 2110. With a locking force of 0, after locking the syringe body 2104, the transparent cover 16 is flipped downwards. Through the combined action of the two positioning plates 13, the damping shaft 14, and the two positioning hooks 15, the transparent cover 16 is rotated. The damping shaft 14 can temporarily limit the transparent cover 16. Without external force, the transparent cover 16 will not rotate on its own. The transparent cover 16 can seal the inside of the shell 11. After the transparent cover 16 completely seals the shell 11, the controller 12 starts the motor 2106. The rotation of the output end of the motor 2106 drives the rotating rod 2101 to rotate. The rotation of motor 101 drives chuck 2102 to rotate, which in turn drives syringe body 2104 to rotate synchronously. The rotation angle of motor 2106 is pre-programmed by controller 12, rotating 90° each time. After syringe body 2104 rotates to the designated position, it connects to the output end of syringe tube 2110 via syringe clamping unit 23. Then, microcontroller switching unit 22 controls the first electric push rod 2108, causing compression plate 2109 to contact one end of piston rod 2111. Subsequently, the retraction of the extension end of the first electric push rod 2108, in conjunction with the compression plate 2109, causes the piston rod 2109 to retract. 109 laterally compresses the piston rod 2111. The movement of the compression plate 2109 and the retraction of the telescopic end of the first electric push rod 2108 are achieved by the engagement and sliding of the first sliding block 2114 and the second sliding block 2116 in the sliding groove 2113, respectively. This stabilizes the movement trajectory of the compression plate 2109 and the telescopic end of the first electric push rod 2108. After being compressed, the piston rod 2111 moves in the inner cavity of the injection tube 2110, allowing the glucose solution to enter the external catheter from the output end of the injection tube 2110 through the syringe clamping unit 23 and into the patient's body, thereby realizing the injection of glucose solution.

[0025] Example 2: Please refer to Figures 1-10 The present invention provides a technical solution: a GLUT1 glucose injection device for septic cardiomyopathy, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0026] As a further definition of the automatic switching mechanism 2 of the present invention, a first positioning block 2202 is fixedly connected to one side of the chuck 2102, four first contact blocks 2203 are fixedly connected to one side of the first positioning block 2202, and four first insulating sleeves 2204 are fixedly connected to one side of the first positioning block 2202. The inner wall of the first insulating sleeve 2204 is fixedly connected to the surface of the first contact block 2203. A conductive ring 2205 is fixedly sleeved on the surface of the rotating rod 2101. The conductive ring 2205 is electrically connected to the first contact block 2203 through a wire. A conductive rod 2206 is rotatably connected to the inner wall of the conductive ring 2205. The conductive rod 2206 is electrically connected to the controller 12. A second insulating sleeve 2207 is fixedly sleeved on the surface of the conductive rod 2206. A support frame 2208 is fixedly connected to one side of the housing 11. The surface of the second insulating sleeve 2207 is fixedly connected to the inner wall of the support frame 2208. An extension plate 2209 is fixedly connected to one side of the connecting plate 2107, and a second contact block 2210 is fixedly connected to one side of the extension plate 2209. The second contact block 2210 is electrically connected to the first electric push rod 2108. Two positioning strips 2211 are fixedly connected to the surface of the microcontroller module 2201. An input contact block 2212 and an output contact block 2213 are fixedly connected to one side of the two positioning strips 2211, respectively. The input contact block 2212 works in conjunction with the first contact block 2203, and the output contact block 2213 works in conjunction with the second contact block 2210. By setting the microcontroller switching unit 22, the parameters of each injection cylinder 2104 can be set individually, realizing customized control of a single injection cylinder 2104 while switching injection cylinders 2104, ensuring the injection accuracy of glucose solution, thereby ensuring the continuity of glucose solution injection and ensuring the injection effect.

[0027] An arc plate 2214 is fixedly connected to one side of the microcontroller module 2201. Two slide rods 2215 are slidably connected to the inner wall of the arc plate 2214. One end of the slide rod 2215 is fixedly connected to one side of the chuck 2102. A spring 2216 is slidably sleeved on the surface of the slide rod 2215. The two ends of the spring 2216 are fixedly connected to one side of the arc plate 2214 and one side of the chuck 2102, respectively. By setting the arc plate 2214, slide rod 2215 and spring 2216 to work together, the injection cylinder clamping unit 23 provides lateral extrusion force, causing the arc plate 2214 to move closer to the chuck 2102 on the surface of the slide rod 2215. At this time, the arc plate 2214 compresses the spring 2216. When the arc plate 2214 loses the lateral extrusion force, the reaction force of the spring 2216 can restore the lateral displacement of the arc plate 2214.

[0028] The specific implementation of this embodiment is as follows: The rotation of the chuck 2102 drives the first positioning block 2202 to rotate synchronously. The rotation of the first positioning block 2202 drives the slide rod 2215 and the arc plate 2214 to rotate. The rotation of the arc plate 2214 drives the microcontroller module 2201 to rotate. The microcontroller module 2201 displays and sets the name, concentration, and injection speed of the solution in the syringe 2104. The microcontroller module 2201 is equivalent to a miniature PLC controller, a mature existing technology, and will not be elaborated further. The rotation of the microcontroller module 2201 drives the output contact block 2213 to rotate to the position corresponding to the second contact block 2210. Through the pushing of the syringe clamping unit 23, the arc plate 2214 moves closer to the chuck 2102 on the surface of the slide rod 2215. At this time, the arc plate 2214 compresses the spring 2216. When the arc plate 2214 loses its lateral compressive force, it can... The lateral displacement of the arc plate 2214 is reset by the reaction force of the spring 2216 until the output contact 2213 contacts the second contact 2210. The microcontroller module 2201 conducts electricity through the rotational connection of the conductive ring 2205 and the conductive rod 2206. The use of the conductive ring 2205 and the conductive rod 2206 avoids the problem of entanglement caused by using wires for conduction. The conductive rod 2206 is electrically connected to the controller 12 through the wire. The first insulating sleeve 2204 and the second insulating sleeve 2207 isolate the current. When the input contact 2212 contacts the first contact 2203, the current is input into the microcontroller module 2201. Then, the current processed by the microcontroller module 2201 is introduced into the second contact 2210 through the output contact 2213, so as to control the first electric push rod 2108 to complete the precise injection of glucose solution into the syringe 2104.

One end of the five connecting rods 2305 is fixedly connected to a connecting tube 2306. One end of the connecting tube 2306 is used in conjunction with the output end of the syringe body 2104, and the other end of the connecting tube 2306 is used in conjunction with an external catheter. By setting the syringe clamping unit 23, the automatic docking of the syringe body 2104 with the external catheter after switching can be realized, ensuring the timeliness and continuity of glucose solution injection and reducing the workload of medical staff.

[0031] A drive plate 2307 is fixedly connected to one side of the movable frame 2302, and a driven plate 2308 is fixedly connected to one side of each of the four arc plates 2214.

Guide blocks 2310 are slidably connected to the inner cavity of the guide grooves 2309. One side of each of the two guide blocks 2310 is fixedly connected to the surface of the movable frame 2302. By setting the drive plate 2307 and the driven plates... 2308 can move the drive plate 2307 by moving the movable frame 2302. The movement of the drive plate 2307 pushes the driven plate 2308, thereby pushing the arc plate 2214 and the micro-control module 2201, and controlling the first electric push rod 2108 to ensure the accuracy of glucose solution injection. The stability of the movable frame 2302 when moving within the receiving hole 2301 is improved by the cooperation of the guide groove 2309 and the guide block 2310.

The inner wall of the cover 2312 is in contact with the external conduit. The buckle 2311, cover 2312, sealing ring 2313 and locking plate 2314 are used together. During installation, the external conduit passes through the middle of the cover 2312, which is equipped with a through hole. Then, the locking plate 2314 is rotated and locked into close contact with the buckle 2311 to achieve positioning of the cover 2312. The sealing ring 2313 achieves close contact between the cover 2312 and the housing 11, ensuring the airtightness of the receiving hole 2301.

[0033] A third electric push rod 2315 is fixedly connected to the bottom of the placement groove 17. An electric gripper 2316 is fixedly connected to the telescopic end of the third electric push rod 2315. The gripping end of the electric gripper 2316 contacts the surface of the injection tube 2110. A limiting plate 2317 is fixedly connected to one side of the electric gripper 2316, and one side of the limiting plate 2317 contacts one side of the injection tube 2110. Through the coordinated use of the third electric push rod 2315, the electric gripper 2316, and the limiting plate 2317, when the injection cylinder 2104 rotates to the designated position, the controller 12 activates the third electric push rod 2315 to extend upwards, thereby driving the electric gripper 2316 upwards. The electric gripper 2316 is in an open state. Sensor technology can be used here, which is a mature technology and will not be elaborated on further. This ensures the accuracy of the electric gripper 2316 in clamping the injection tube 2110. Subsequently, the electric gripper 2316 is controlled by the controller 12 to clamp the injection tube 2110. The limiting plate 2317 can limit the lateral displacement of the injection tube 2110, ensuring that the injection tube 2110 has sufficient lateral force when the second electric push rod 2304 is connected to the external conduit and the output end of the injection tube 2110, thereby ensuring the stability when the external conduit and the output end of the injection tube 2110 are connected.

[0034] The specific implementation method of this embodiment is as follows: After the switching of the injection cylinder 2104 is completed, the second electric actuator 2304 is activated by the controller 12. The telescopic end of the second electric actuator 2304 extends. Before injection, the external conduit passes through the middle of the cover 2312. The middle of the cover 2312 is equipped with a through hole. The external conduit is sleeved on one end of the connecting tube 2306 and connected to the connecting tube 2306. The connecting tube 2306 is tapered at both ends to facilitate the fitting between the external conduit and the output end of the injection tube 2110 and the connecting tube 2306. Then, by pressing the clip... Plate 2314 rotates and engages with buckle 2311 to achieve tight contact, positioning cover 2312. Sealing ring 2313 ensures tight contact between cover 2312 and housing 11, guaranteeing a tight seal against obstruction of receiving hole 2301. The other end of external catheter is connected to the patient, such as the tubing of indwelling needle. Extension of the telescopic end of second electric push rod 2304 pushes moving frame 2302 within the cavity of receiving hole 2301. During movement, moving frame 2302 drives two guide blocks 2310 to slide within the cavities of two guide grooves 2309, increasing the mobility of moving frame 2302. During operation, the movement of the movable frame 2302 drives the five connecting rods 2305 and the connecting tube 2306 with the external conduit to move until one end of the connecting tube 2306 is fully embedded in the inner cavity of the output end of the injection tube 2110. Simultaneously, the movable frame 2302 moves, pushing the drive plate 2307 to move. The movement of the drive plate 2307 then pushes the driven plate 2308 to move, thereby driving the microcontroller module 2201. When the injection cylinder 2104 rotates to the designated position, the controller 12 activates the third electric push rod 2315 to extend upwards, thereby driving the electric clamp. The claw 2316 moves upward, and the clamping end of the electric gripper 2316 is in an open state. Sensing technology can be used here to ensure the accuracy of the electric gripper 2316 in clamping the injection tube 2110. Subsequently, the electric gripper 2316 is controlled by the controller 12 to clamp the injection tube 2110. The limiting plate 2317 can limit the lateral displacement of the injection tube 2110, ensuring that the injection tube 2110 has sufficient lateral force when the second electric push rod 2304 is docked with the external conduit and the output end of the injection tube 2110, thereby ensuring the stability of the external conduit docking.
