Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a nutrient solution infusion device for gastrointestinal patients. Background Technology

[0002] Gastrointestinal surgery primarily focuses on treating diseases of the digestive tract, mainly diseases of the stomach, pancreas, small intestine, and large intestine. When patients experience digestive problems, surgery may be necessary. For some post-operative patients, especially those who have undergone esophagectomy, physiological changes prevent oral nutrition, necessitating a liquid diet or intravenous nutrition to meet their nutritional needs. This ensures the body receives the necessary nutrients, promoting recovery.

[0003] Currently, traditional nutrient infusion sets require medical staff to first prepare a variety of nutrient solution ingredients. These ingredients cover a wide range, such as proteins rich in key substances needed for body repair, carbohydrates that provide energy for the human body, fat emulsions that are essential for maintaining normal physiological functions, electrolytes that regulate the balance of the body's internal environment, as well as vitamins, minerals, trace elements that promote body metabolism and maintain life activities, and liquids that serve as solvents.

[0004] After preparing these ingredients, medical staff will place them into a specific container and connect it to a feeding tube attached to the patient's abdomen to deliver nutritional fluids. However, this traditional method has a significant problem: it is mostly done manually. Manual preparation means that medical staff must rely on their experience and intuition to add various ingredients, making it highly susceptible to human error. Different medical staff may have different judgments about the amount of ingredients to add, and even a slight error can lead to inaccurate control of the amount of nutritional fluid added. Once the amount of nutritional fluid added is deviated, it will not only affect the composition ratio of the nutritional fluid, preventing it from reaching the optimal ratio for the patient's needs, but it will also directly reduce the accuracy and efficiency of the nutritional fluid delivery process. Summary of the Invention

Drive component two is located inside the sealed housing and is capable of driving the gear ring to rotate.

[0009] Preferably, the second drive assembly includes a second motor fixedly connected inside the sealed housing. A rotating disk is fixedly installed at the output end of the second motor. A connecting ring is provided at the bottom end of the rotating disk. A protrusion located inside the connecting ring is fixedly installed at the bottom end of the rotating disk. A rack is fixedly installed at the bottom end of the connecting ring.

[0010] Preferably, it further includes: A cleaning mechanism is located inside the housing. The cleaning mechanism includes a rotating block rotatably connected inside the housing. A rotating rod located inside the liquid mixing tank is fixedly installed at the top of the rotating block. Two mounting rings are fixedly sleeved on the surface of the rotating rod. A stirring plate and a cleaning plate are fixedly installed on the surface of the two mounting rings, respectively. A connecting rod is fixedly installed on the outer surface of the rotating block. A second connecting block is slidably connected inside the connecting rod, and the top of the second connecting block is fixedly connected to the bottom of the heating plate.

[0011] Preferably, it further includes: A limiting component is disposed at the top of the inside of the sealing shell. The limiting component includes two limiting grooves formed at the top of the inside of the sealing shell. A limiting rod is slidably connected inside the two limiting grooves, and the bottom end of the limiting rod is fixedly connected to the surface of the rack.

[0012] Preferably, it further includes: An extraction assembly is disposed inside the housing. The extraction assembly includes an extraction pump fixedly connected inside the housing. A connecting pipe is fixedly installed at the output end of the extraction pump, and one end of the connecting pipe is fixed to the surface of the liquid preparation tank by a retaining ring.

[0013] Preferably, the surface of the protrusion is cylindrical and smooth, and the surface of the protrusion fits against the inner wall of the connecting ring.

[0014] Preferably, the limiting ring is a T-shaped design, and the surface of the limiting ring is in contact with the inner wall of the liquid preparation tank.

[0015] Preferably, a semi-circular hole is provided at the bottom of the housing, and the connecting block 2 can slide inside the semi-circular hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a motor to drive a lead screw to rotate, causing a hinge block to slide on the surface of the lead screw. This hinge block then drives a slider to slide on the surface of a slide rail. The slider moves a connecting block and a sealing plate, which then releases the seal on the storage container. The nutrient solution material passes through the pipe and the guide shell into the mixing tank. After the nutrient solution material reaches the infusion parameters in each channel, the control module drives the drive assembly to reset the sealing plate. The sealing plate can then seal the storage container. Finally, by driving the drive assembly, the sealing plate can open or close the storage container. Subsequently, the control module accurately controls the amount of nutrient solution added. This significantly improves the accuracy and efficiency of the nutrient solution addition operation and ensures a stable and reliable process. This invention drives a heating plate, which heats the nutrient solution inside the dispensing tank. During the heating process, a second motor drives a rotating disk to rotate. The rotating disk causes a protrusion to slide inside a connecting ring. The protrusion pushes the connecting ring and rack to move back and forth. The rack then drives a toothed ring to rotate back and forth. The toothed ring, in turn, drives the rotating plate, the limiting ring, and the heating plate to rotate back and forth around the surface of the dispensing tank. Ultimately, the heating plate effectively heats the nutrient solution, preventing cold nutrient solution from irritating the patient's digestive tract and causing discomfort. Furthermore, the rotation of the heating plate increases the heating area of ​​the nutrient solution, making the nutrient solution heat more evenly. This invention utilizes a heating plate that, during its reciprocating rotation, drives a connecting rod via a second linkage block. This connecting rod, in turn, causes the rotating block, rotating rod, mounting ring, stirring plate, and cleaning plate to rotate. The rotation of the stirring and cleaning plates effectively agitates and cleans any residual nutrient solution from the inner wall of the mixing tank. The rotation of the stirring and cleaning plates, linked by the heating plate and connecting block, ensures thorough mixing of various nutrient solution ingredients. Furthermore, the brush bristles at the bottom of the stirring plate contact the bottom of the mixing tank, preventing nutrient solution sedimentation. During rotation, the cleaning plate's surface contacts the inner wall of the mixing tank, scraping away any remaining nutrient solution. This significantly reduces the possibility of nutrient solution residue, minimizes resource waste, and provides a reliable guarantee for the entire nutrient solution processing and transportation process.

[0019] 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.

[0020] like Figures 1 to 8 As shown, the present invention provides a gastrointestinal nutrient solution infusion device for patients, including a housing 1, and further comprising: Control mechanism 2 is located inside housing 1; The control mechanism 2 includes a liquid storage container 201 located inside the top of the housing 1. The bottom of the liquid storage container 201 is connected to a square block 202 located inside the housing 1 by a retaining ring. Two sealing plates 203 are slidably connected inside the square block 202. A slide rail 204 is fixedly installed inside the square block 202. A slider 205 is slidably connected to the surface of the slide rail 204. A connecting block 206 is fixedly installed at the top of the sealing plate 203 and is fixedly connected to the slider 205. A liquid mixing tank 207 is fixed to the bottom of the housing 1 by bolts. A flow guide shell 208 is connected to the top of the liquid mixing tank 207 and is connected to the square block 202 by a pipe. The drive component 3 is located inside the square block 202 and can drive the sealing plate 203 to move.

[0021] Using the above scheme: Operators inject the nutrient solution raw materials into the three storage containers 201 respectively. Then, using the control panel on one side of the housing 1, after setting the infusion parameters for each channel of the nutrient solution raw material, the control module precisely controls the start of the drive component 3 based on these parameters. Drive component 3 then drives the sealing plate 203 to move, which in turn moves the slider 205 and the connecting block 206. The slider 205 slides on the surface of the slide rail 204. Next, the sealing plate 203 releases the seal on the storage container 201, allowing the raw material to pass through the pipe and the guide shell 208 into the mixing tank 207. After the nutrient solution raw materials in each channel reach the infusion parameters, the control module will again drive drive component 3... The sealing plate 203 is reset, and the sealing plate 203 can seal the liquid storage container 201. Finally, the sealing plate 203 is opened or sealed by the drive component 3. Then, the amount of nutrient solution added is accurately controlled by the control module. In this way, the accuracy and efficiency of the nutrient solution addition operation are significantly improved, and the process is stable and reliable. The liquid storage container 201 is set at the top of the shell 1. The liquid storage container 201 and the square block 202 are connected by a retaining ring, so they can be disassembled. Then the liquid mixing tank 207 and the guide shell 208 can be disassembled, so that their components can be disinfected. This fully demonstrates the equipment's hygiene, safety and ease of use.

[0022] like Figure 4 As shown, the drive assembly 3 is fixedly connected to the motor 301 inside the liquid storage container 201. The output end of the motor 301 is fixedly installed with a lead screw 302. The surface of the lead screw 302 is threaded with a hinge block 303. The hinge block 303 and the slider 205 are hinged together by a hinge rod 304.

[0023] Using the above scheme: Through the design of drive component 3, the control module will drive motor 301 to start, and the output end of motor 301 will drive lead screw 302 to rotate. Since lead screw 302 is threadedly connected to hinge block 303, when lead screw 302 rotates, hinge block 303 will slide on the surface of lead screw 302. Since hinge block 303 and slider 205 are hinged through hinge rod 304, the moving hinge block 303 will push hinge rod 304 to rotate, hinge rod 304 will push slider 205 to slide on the surface of slide rail 204, and slider 205 will drive connecting block 206 and sealing plate 203 to move.

[0024] like Figure 6 and Figure 7 As shown, it also includes: The rotating mechanism 4 is located inside the housing 1. The rotating mechanism 4 includes a sealing shell 401 located inside the housing 1 and the sealing shell 401 is sleeved on the surface of the liquid preparation tank 207. A limiting ring 402 is rotatably connected inside the top of the sealing shell 401. A rotating plate 403 is fixedly installed at the top of the limiting ring 402. A toothed ring 404 is fixedly installed at the top of the rotating plate 403. Heating plates 405 located on the outer surface of the liquid preparation tank 207 are fixedly installed at both ends of the bottom of the rotating plate 403. Drive component 2 5 is located inside the sealing shell 401 and is capable of driving the gear ring 404 to rotate.

[0025] The above scheme is adopted as follows: Through the design of the rotating mechanism 4, after various nutrient solution raw materials are injected into the solution preparation tank 207, the heating plate 405 can be driven. The heating plate 405 will bake the surface of the solution preparation tank 207, thereby heating the nutrient solution inside the solution preparation tank 207. During the heating process of the heating plate 405, the driving component 2 5 can be driven to make the toothed ring 404 reciprocate. The toothed ring 404 will drive the rotating plate 403, the limiting ring 402 and the heating plate 405 to reciprocate around the surface of the solution preparation tank 207. Finally, the nutrient solution is effectively heated by the heating plate 405, avoiding the cold nutrient solution from irritating the patient's digestive tract and causing discomfort. Furthermore, the driving component 2 5 drives the heating plate 405 to reciprocate. The rotation of the heating plate 405 can increase the heating area of ​​the nutrient solution and make the nutrient solution heat more evenly. The sealing shell 401 is fixed to the inside of the shell 1 by bolts. After the sealing shell 401 is removed, the solution preparation tank 207 inside can be disassembled.

[0026] like Figure 6 As shown, the second drive assembly 5 includes a second motor 501 fixedly connected inside the sealed housing 401. A rotating disk 502 is fixedly installed at the output end of the second motor 501. A connecting ring 503 is provided at the bottom end of the rotating disk 502. A protrusion 504 located inside the connecting ring 503 is fixedly installed at the bottom end of the rotating disk 502. A rack 505 is fixedly installed at the bottom end of the connecting ring 503.

[0027] Using the above solution: Through the design of the second drive component 5, the second motor 501 can be driven to rotate the rotating disk 502. The rotating disk 502 will drive the protrusion 504 to slide inside the connecting ring 503. During the sliding process, the protrusion 504 will push the connecting ring 503 and the rack 505 to move back and forth. Because the rack 505 meshes with the toothed ring 404, the rack 505 will drive the toothed ring 404 to rotate back and forth.

[0028] like Figure 7 and Figure 8 As shown, it also includes: The cleaning mechanism 6 is located inside the housing 1. The cleaning mechanism 6 includes a rotating block 601 rotatably connected inside the housing 1. A rotating rod 602 located inside the liquid preparation tank 207 is fixedly installed on the top of the rotating block 601. Two mounting rings 603 are fixedly sleeved on the surface of the rotating rod 602. A stirring plate 604 and a cleaning plate 605 are fixedly installed on the surface of the two mounting rings 603, respectively. A connecting rod 606 is fixedly installed on the outer surface of the rotating block 601. A connecting block 607 is slidably connected inside the connecting rod 606, and the top of the connecting block 607 is fixedly connected to the bottom of the heating plate 405.

[0029] Using the above solution: Through the design of the cleaning mechanism 6, during the reciprocating rotation of the heating plate 405, the heating plate 405 will slide in conjunction with the connecting block 607 inside the connecting rod 606. During the sliding process, the connecting block 607 will drive the connecting rod 606 to reciprocate, and the connecting rod 606 will drive the rotating block 601 and the rotating rod 602 to reciprocate. The rotating rod 602 will drive the mounting ring 603, the stirring plate 604, and the cleaning plate 605 to reciprocate. During the rotation of the stirring plate 604 and the cleaning plate 605, the nutrient solution can be stirred and the inner wall of the solution preparation tank 207 can be cleaned. Finally, the stirring plate 604 and the cleaning plate 605 are rotated by the linkage connecting block 607 of the heating plate 405, ensuring that the various nutrient solution raw materials are fully combined. The bristles at the bottom of the stirring plate 604 contact the bottom of the inside of the mixing tank 207, thereby preventing the nutrient solution from settling. Then, during the rotation, the surface of the cleaning plate 605 contacts the inner wall of the mixing tank 207, thereby scraping off the nutrient solution remaining on the inner wall of the mixing tank 207, greatly reducing the possibility of nutrient solution residue, reducing resource waste, and providing a reliable guarantee for the entire nutrient solution processing and transportation process.

[0030] like Figure 6 and Figure 7 As shown, it also includes: The limiting component 7 is located at the top of the inside of the sealing shell 401. The limiting component 7 includes a limiting groove 701 opened at the top of the inside of the sealing shell 401. There are two limiting grooves 701. The two limiting grooves 701 are slidably connected to the inside of the limiting rods 702, and the bottom end of the limiting rods 702 is fixedly connected to the surface of the rack 505.

[0031] The above solution is adopted: through the design of the limiting component 7, when the rack 505 moves, it will drive the limiting rod 702 to slide inside the limiting groove 701. During the sliding process, the limiting groove 701 can support the limiting rod 702 and the rack 505 to ensure the stability of the rack 505 movement.

[0032] like Figure 2 and Figure 5 As shown, it also includes: The extraction component 8 is located inside the housing 1. The extraction component 8 includes an extraction pump 801 fixedly connected inside the housing 1. A connecting pipe 802 is fixedly installed at the output end of the extraction pump 801, and one end of the connecting pipe 802 is fixed to the surface of the liquid preparation tank 207 by a retaining ring.

[0033] Using the above scheme: Through the design of the extraction component 8, after the nutrient solution is mixed, the nutrient tube connected to the patient's abdomen can be connected to the other end of the connecting tube 802. Then, the extraction pump 801 can be driven to draw the nutrient solution inside the solution tank 207 through the connecting tube 802. The nutrient solution will then pass through the connecting tube 802 and the nutrient tube connected to the patient's abdomen and enter the patient's abdomen. The extraction speed of the extraction pump 801 can be controlled according to the patient's absorption rate. One end of the connecting tube 802 is fixed to the surface of the solution tank 207 by a retaining ring, thereby enabling the entire extraction component 8 to be disassembled and disinfected.

[0034] like Figure 6 As shown, the surface of the protrusion 504 is cylindrical and smooth, and the surface of the protrusion 504 fits against the inner wall of the connecting ring 503.

[0035] The above solution is adopted: through the design of the protrusion 504, since the surface of the protrusion 504 is cylindrical and smooth, the protrusion 504 can slide smoothly inside the connecting ring 503, and the surface of the protrusion 504 fits against the inner wall of the connecting ring 503, ensuring that the protrusion 504 pushes the connecting ring 503 to move normally.

[0036] like Figure 6 and Figure 8 As shown, the limiting ring 402 is a T-shaped design, and the surface of the limiting ring 402 is in contact with the inner wall of the liquid preparation tank 207. A semi-circular hole is opened at the bottom of the housing 1, and the connecting block 607 can slide inside the semi-circular hole.

[0037] The above solution is adopted: By designing the limiting ring 402, since the limiting ring 402 is T-shaped, it can limit the rotation plate 403, the toothed ring 404 and the heating plate 405 when the limiting ring 402 rotates, ensuring the stable rotation of the components. By designing the housing 1, since the bottom of the housing 1 is provided with a semi-circular hole, the connecting block 607 can slide inside the semi-circular hole when it moves, so the housing 1 will not interfere with the sliding of the connecting block 607 and the connecting rod 606.

[0038] Working principle and usage process of this invention: First, the operator injects the nutrient solution raw materials into the three storage containers 201 respectively. Then, using the control panel on one side of the housing 1, after setting the infusion parameters of the nutrient solution for each channel, the control module precisely controls the motor 301 to start according to these parameters. The motor 301 drives the lead screw 302 to rotate, and the hinge block 303 slides on the surface of the lead screw 302. The hinge block 303 pushes the hinge rod 304 to rotate, and the hinge rod 304 pushes the slider 205 to slide on the surface of the slide rail 204. The slider 205 drives the connecting block 206 and the sealing plate 203 to move. The sealing plate 203 will unblock the storage container 201, and the nutrient solution raw materials will pass through the pipe and the guide shell 208 into the liquid preparation tank 207. After the nutrient solution raw materials in each channel reach the infusion parameters, the control module will drive the drive component 3 again to reset the sealing plate 203. The sealing plate 203 can block the storage container 201. After various nutrient solution ingredients are injected into the mixing tank 207, the heating plate 405 can be driven to heat the nutrient solution inside the mixing tank 207. During the heating process of the heating plate 405, the motor 501 can be driven to rotate the rotating disk 502. The rotating disk 502 will drive the protrusion 504 to slide inside the connecting ring 503. The protrusion 504 will push the connecting ring 503 and the rack 505 to move back and forth. In turn, the rack 505 will drive the toothed ring 404 to rotate back and forth. The toothed ring 404 will drive the rotating plate 403, the limiting ring 402 and the heating plate 405 to rotate back and forth around the surface of the mixing tank 207, thereby heating the nutrient solution evenly. During the reciprocating rotation of the heating plate 405, the heating plate 405 will slide in conjunction with the connecting block 607 inside the connecting rod 606. During the sliding process, the connecting block 607 will drive the connecting rod 606 to reciprocate. The connecting rod 606 will drive the rotating block 601 and the rotating rod 602 to reciprocate. The rotating rod 602 will drive the mounting ring 603, the stirring plate 604, and the cleaning plate 605 to reciprocate. During the rotation of the stirring plate 604 and the cleaning plate 605, the nutrient solution can be stirred and the residual nutrient solution on the inner wall of the solution tank 207 can be cleaned. Then, the extraction pump 801 can be driven to draw the nutrient solution inside the solution tank 207 through the connecting pipe 802. Then, the nutrient solution will pass through the connecting pipe 802 and the nutrient tube connected to the patient's abdomen and enter the patient's abdomen, thus completing the operation process.
