Technical Field

[0001] The present invention relates to the technical field of parenteral nutrition solution preparation, in particular to a multifunctional device for preparing parenteral nutrition solution. Background Art

[0002] Parenteral nutrition solution is an important means of clinical nutritional support. Its ingredients include large-volume medicines such as glucose, amino acids, and fat emulsion, as well as micronutrients such as electrolytes, vitamins, and trace elements. Some patients are unable to eat orally or oral intake cannot meet their nutritional needs. They need to use intravenous injection of parenteral nutrition solution to provide nutrients for patients. When using parenteral nutrition solution on patients, different types of nutrient solution raw materials need to be prepared according to needs.

The complex composition makes the manual and semi-automatic operation processes cumbersome and the batch preparation efficiency low. Summary of the Invention

One end of the No. 2 connecting shaft 96 is rotatably connected to the upper part of the placement rack 8, and the other end of the No. 2 connecting shaft 96 is fixedly connected to a cam 97, and the cam 97 is in contact with the upper part of the limit frame 98.

[0032] The oscillation mechanism 6 includes a fixed shell 61, a shock-absorbing base 62 is fixedly connected to the interior of the second connecting shaft 96, a telescopic bracket 63 is installed on the upper part of the shock-absorbing base 62, a fixed plate 65 is installed on the upper part of the telescopic bracket 63, and an oscillation component 64 is installed on the bottom of the fixed plate 65. The upper part of the operating table 1 is respectively installed with a code scanning gun 4, an industrial camera 5 and a human-computer interface 10. The code scanning gun 4 and the industrial camera 5 are both located at the front end of the placement rack 8, and the industrial camera 5 is located on the side of the code scanning gun 4. The code scanning gun 4 and the industrial camera 5 are both electrically connected to the human-computer interface 10;

[0033] The linkage mechanism 13 includes a number one synchronous wheel 131, a synchronous belt 132 and a number two synchronous wheel 133. The number one synchronous wheel 131 is fixedly connected to the surface of the number one connecting shaft 76, the number two synchronous wheel 133 is fixedly connected to the end of the number two connecting shaft 96, and the synchronous belt 132 is movably connected to the number one synchronous wheel 131 and the number two synchronous wheel 133 respectively.

[0034] The following is a detailed description of the specific settings and functions of this embodiment. First, the swaying mechanism 7 is turned on and operated through the human-computer interface 10. At this time, the servo reduction motor 75 is installed with a setting program to rotate the placement rack 8 to a certain angle, which is convenient for medical staff to insert the bag from one end of the placement rack 8. The bottom of the bag is limited by the baffle at the end of the placement rack 8. After the bag is placed, the bag is facing the barcode scanner 4. The barcode scanner 4 scans the parenteral nutrition solution prescription label on the bag, and the information is displayed through the human-computer interface 10. The information of each component can be checked or modified through the human-computer interface 10.

[0035] Each nutrient bag or nutrient bottle is hung on the hook 2, and the bag placed inside the placement rack 8 is connected to the hanging nutrient bag or nutrient bottle through a connecting pipe. A valve is provided on the upper part of the pipe. When installing the pipe, the pipe is connected to the flow sensor 3. Nutrient elements are injected into the bag in sequence according to the doctor's prescription label and the standard order. The amount of nutrient elements flowing into the bag is accurately monitored by the flow sensor 3.

[0036] When various nutrients are injected into the bag, the oscillation assembly 64 drives the fixed plate 65 and the swaying mechanism 7 on the upper portion thereof to oscillate, so that the nutrient solution in the bag is mixed during the injection process.

[0037] At the same time, the servo reduction motor 75 drives the placement rack 8 to swing back and forth in the vertical direction at an angle of 45° to -45°, so that the nutrient solution in the bag is fully mixed. In the process of the servo reduction motor 75 driving the placement rack 8 to swing back and forth in the vertical direction, the No. 1 synchronous wheel 131 will drive the synchronous belt 132 and the No. 2 synchronous wheel 133 to rotate back and forth, and at this time drive the No. 2 connecting shaft 96 and the cam 97 to push the limit rack 98 back and forth, and the limit rack 98 will drive the mounting plate 95 to move. At this time, the No. 2 slider 92 slides along the No. 2 slide rail 91 and the guide rod 93, and at the same time, the No. 1 spring 94 produces telescopic deformation. During the telescopic deformation of the No. 1 spring 94, the mounting plate 95 and the pressure plate 910 at the bottom thereof will be driven to perform reciprocating motion up and down, thereby producing a pinching and releasing effect on the nutrient solution in the bag, causing the internal nutrient solution to shake, thereby fully mixing it.

[0038] The flow sensor 3 on the operating table 1 cooperates with the hook 2 to achieve precise measurement of nutrient elements during injection, solving the problem of manual extraction errors. The oscillation component 64 in the oscillation mechanism 6 drives the shaking mechanism 7 to make the placement rack 8 swing back and forth from 45° to -45° in the vertical direction. At the same time, the linkage mechanism 13 drives the auxiliary mechanism 9 through the No. 1 synchronous wheel 131, the synchronous belt 132 and the No. 2 synchronous wheel 133. The cooperation of the cam 97 and the limit frame 98 is used to make the No. 2 slider 92 slide in the No. 2 slide rail 91 and drive the pressure plate 910 to pinch and release the bag body through the No. 1 spring 94, forming a "oscillation + swing + pinch and release" three-dimensional mixing mode to ensure that the nutrient solution is fully mixed while being injected, effectively avoiding stratification and precipitation; the barcode scanning gun 4 and the industrial camera 5 cooperate with the human-computer interface 10 to realize automatic reading and verification of the medical order label information, improve the intelligence and accuracy of the preparation process, and the full-process automation design improves the liquid preparation efficiency and mixing uniformity, while reducing the risk of contamination from manual operation to meet the clinical precision nutritional support needs.

[0039] Example 2: Figure 4-Figure 8 As shown, a No. 2 electric push rod 99 is fixedly connected to the bottom of the mounting plate 95, and the bottom of the No. 2 electric push rod 99 is fixedly connected to the pressure plate 910. A pressure sensor is installed on the surface of the pressure plate 910, and a telescopic rod 911 is fixedly connected to the upper part of the pressure plate 910. The telescopic rod 911 is fixedly connected to the mounting plate 95, and a No. 2 spring 912 is provided on the surface of the telescopic rod 911. The two ends of the No. 2 spring 912 are respectively fixedly connected to the mounting plate 95 and the pressure plate 910.

[0040] The swinging mechanism 7 includes a mounting frame 71, which is fixedly connected to the upper part of the fixed plate 65, and the upper part of the mounting frame 71 is fixedly connected to a No. 1 slide rail 72, and the upper part of the No. 1 slide rail 72 is movably connected to two groups of No. 1 sliders 73, and the upper parts of the two groups of No. 1 sliders 73 are respectively fixedly connected to a support frame 74, and the upper part of the support frame 74 is rotatably connected to a No. 1 connecting shaft 76. A servo reduction motor 75 is installed on the side of a support frame 74, and the output end of the servo reduction motor 75 is fixedly connected to the end of the No. 1 connecting shaft 76, and the end of the No. 1 connecting shaft 76 is fixedly connected to a placement frame 8.

[0041] The effect achieved by the entire embodiment is that the servo reduction motor 75 drives the placement rack 8 to swing back and forth in the vertical direction at an angle of 45° to -45°, so that the nutrient solution in the bag is fully mixed. When the nutrient solution in the bag gradually increases, the second electric push rod 99 is retracted to maintain a suitable height between the pressing plate 910 and the bag body, ensuring that the nutrient solution inside the bag body has enough flow space to facilitate mixing. This process is monitored by the pressure sensor at the bottom of the pressing plate 910. During the process of squeezing the bag body, if the pressure is too high, it means that the distance between the pressing plate 910 and the bag body is too small, otherwise the distance is too large.

[0042] The servo reduction motor 75 in the shaking mechanism 7 drives the No. 1 connecting shaft 76, driving the placement rack 8 to swing back and forth in the range of 45° to -45°, cooperating with the oscillation component 64 of the oscillation mechanism 6 to form a three-dimensional hybrid power; in the auxiliary mechanism 9, the No. 2 electric push rod 99 adjusts the height of the pressure plate 910 in real time according to the amount of nutrient solution in the bag, and the pressure sensor monitors the extrusion pressure. When the liquid level rises, the electric push rod is retracted to maintain a suitable distance between the pressure plate 910 and the bag body to avoid excessive extrusion or insufficient mixing space. At the same time, the telescopic rod 911 and the No. 2 spring 912 provide elastic buffering, which can ensure the mixing force and prevent sudden pressure changes when the pressure plate 910 pinches the bag body. It can adapt to the dynamic mixing requirements of nutrient solutions of different capacities and eliminate the attenuation of mixing efficiency due to liquid level changes. At the same time, the pressure sensor links the electric push rod to form a closed-loop control to ensure that the mixing process is safe and damage-free.

[0043] Example 3: Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a No. 2 electric push rod 99 is fixedly connected to the bottom of the mounting plate 95, and the bottom of the No. 2 electric push rod 99 is fixedly connected to the pressure plate 910. A pressure sensor is installed on the surface of the pressure plate 910, and a telescopic rod 911 is fixedly connected to the upper part of the pressure plate 910. The telescopic rod 911 is fixedly connected to the mounting plate 95, and a No. 2 spring 912 is provided on the surface of the telescopic rod 911. The two ends of the No. 2 spring 912 are fixedly connected to the mounting plate 95 and the pressure plate 910 respectively.

[0044] The swaying mechanism 7 includes a mounting frame 71, which is fixedly connected to the upper portion of the fixed plate 65, and the upper portion of the mounting frame 71 is fixedly connected to a No. 1 slide rail 72, and the upper portion of the No. 1 slide rail 72 is movably connected with two groups of No. 1 sliders 73, and the upper portions of the two groups of No. 1 sliders 73 are respectively fixedly connected to a support frame 74, and the upper portion of the support frame 74 is rotatably connected to a No. 1 connecting shaft 76, and a servo reduction motor 75 is installed on the side of one support frame 74, and the output end of the servo reduction motor 75 is fixedly connected to the end of the No. 1 connecting shaft 76, and the end of the No. 1 connecting shaft 76 is fixedly connected to a placement frame 8, and a baffle is provided at one end of the placement frame 8, and a limit rod 11 is fixedly connected to the bottom of one placement frame 8, and a sleeve 12 is fixedly connected to the bottom of the other placement frame 8, and the limit rod 11 is plugged into the sleeve 12, and a No. 1 electric push rod 77 is installed on the side of one support frame 74, and the other end of the No. 1 electric push rod 77 is fixedly connected to the side of the other support frame 74.

[0045] The effect achieved by the entire embodiment is that after various nutrient elements are injected into the bag body, the placement rack 8 is driven to rotate by the servo reduction motor 75, so that the connection end of the bag body and the pipeline is placed upwards. At this time, the gas in the bag body will be stored at the upper end, and the two support racks 74 are driven to move closer to each other by the No. 1 electric push rod 77, thereby driving the two placement racks 8 to move closer to each other, squeezing and exhausting the bag body, and at the same time, the No. 2 electric push rod 99 is extended to push the pressure plate 910 to squeeze and exhaust the bag body. At the same time, the baffle at the end of the placement rack 8 and the placement rack 8 itself have been used to limit the five sides of the bag body, thereby ensuring the stability of the bag body during the exhaust process and improving the exhaust stability. The gas discharge situation in the bag body is monitored by the industrial camera 5. When the image information collected by the industrial camera 5 is determined by the industrial control system inside the human-computer interface 10 to have completed the exhaust of the bag body, the No. 1 electric push rod 77 and the No. 2 electric push rod 99 are extended to complete the preparation of the nutrient solution.

[0046] At the same time, the present invention can also quickly and stably configure the three-chamber bag nutrient solution. Since the three-chamber bag nutrient solution needs to be squeezed with great force by medical staff to connect the three chambers during use, the three-chamber bag nutrient solution is placed on the surface of the placement rack 8, and the No. 2 electric push rod 99 pushes the pressure plate 910 downward to uniformly pressurize the three-chamber bag nutrient solution, so that the channels between the three chambers are quickly opened. When the nutrient solution stored in the three-chamber bag nutrient solution is less, the No. 1 electric push rod 77 drives the placement rack 8 to move closer to each other while extending the No. 2 electric push rod 99 to push the pressure plate 910, thereby improving the applicability of the device.

[0047] After the nutrient solution is injected into the bag, the servo reduction motor 75 drives the placement rack 8 to rotate so that the gas gathers at the upper end. The No. 1 electric push rod 77 pushes the two groups of support racks 74 to move toward each other through the No. 1 slide rail 72, and cooperates with the plug-in structure of the limit rod 11 and the sleeve 12 to make the placement rack 8 squeeze the bag. At the same time, the No. 2 electric push rod 99 drives the pressure plate 910 to press down, and the pressure sensor on the surface of the pressure plate 910 is used to monitor the squeezing force. The telescopic rod 911 and the No. 2 spring 912 provide elastic buffering, and combined with the end baffle of the placement rack 8 to form a five-sided limiting structure to ensure that the exhaust process is stable and leak-free; the industrial camera 5 collects the bag image in real time, and the electric push rod is automatically reset after the human-computer interface 10 determines that the exhaust is completed. For three-chamber bags, the No. 2 electric push rod 99 drives the pressure plate 910 to apply pressure evenly, breaking through the laborious bottleneck of traditional manual squeezing. When the liquid level of the three-chamber bag is low, the No. 1 electric push rod 77 and the No. 2 electric push rod 99 work together to adapt to the mixing needs of bags of different capacities by approaching the placement rack 8 and pressing down the pressure plate 910, shortening the connection time of the three chambers, improving the adequacy of exhaust, and significantly improving the mixing efficiency and clinical applicability.

[0048] The method of using and working principle of this device: First, the shaking mechanism 7 is turned on and operated through the human-computer interface 10. At this time, the servo reduction motor 75 is installed with a setting program to rotate the placement rack 8 to a certain angle, which is convenient for medical staff to insert the bag from one end of the placement rack 8. The bottom of the bag is limited by the baffle at the end of the placement rack 8. After the bag is placed, the bag is facing the barcode scanner 4. The barcode scanner 4 scans the parenteral nutrition solution prescription label on the bag. The information is displayed through the human-computer interface 10, and the information of each component can be checked or modified through the human-computer interface 10;

[0049] Each nutrient bag or nutrient bottle is hung on the hook 2, and the bag placed inside the placement rack 8 is connected to the hanging nutrient bag or nutrient bottle through a connecting pipe. A valve is provided on the upper part of the pipe. When installing the pipe, the pipe is connected to the flow sensor 3. Nutrient elements are injected into the bag in sequence according to the doctor's prescription label and the standard order. The amount of nutrient elements flowing into the bag is accurately monitored by the flow sensor 3.

[0050] When various nutrients are injected into the bag, the oscillation assembly 64 drives the fixed plate 65 and the swaying mechanism 7 on its upper portion to oscillate, so that the nutrient solution in the bag is mixed during the injection process. At the same time, the servo reduction motor 75 drives the placement rack 8 to swing back and forth in the vertical direction at an angle of 45° to -45°, so that the nutrient solution in the bag is fully mixed.

[0051] When the servo reduction motor 75 drives the placement rack 8 to swing back and forth in the vertical direction, the No. 1 synchronous wheel 131 drives the synchronous belt 132 and the No. 2 synchronous wheel 133 to rotate back and forth, and at this time drives the No. 2 connecting shaft 96 and the cam 97 to push the limit rack 98 back and forth, and the limit rack 98 drives the mounting plate 95 to move. At this time, the No. 2 slider 92 slides along the No. 2 slide rail 91 and the guide rod 93, and at the same time, the No. 1 spring 94 produces telescopic deformation. During the telescopic deformation of the No. 1 spring 94, the mounting plate 95 and the pressure plate 910 at the bottom thereof are driven to reciprocate up and down, thereby producing a pinching and releasing effect on the nutrient solution in the bag body, causing the internal nutrient solution to shake, thereby fully mixing it;

[0052] When the amount of nutrient solution in the bag gradually increases, the second electric push rod 99 is retracted to maintain a suitable height between the pressing plate 910 and the bag, ensuring that the nutrient solution inside the bag has enough space to flow and is easy to mix. This process is monitored by the pressure sensor at the bottom of the pressing plate 910. When the pressure is too high during the squeezing of the bag, it means that the distance between the pressing plate 910 and the bag is too small, otherwise it is too large.

[0053] After various nutrient elements are injected into the bag, the placement rack 8 is driven to rotate by the servo reduction motor 75 so that the connection end of the bag and the pipeline is placed upward. At this time, the gas in the bag will be stored at the upper end, and the two support racks 74 are driven to approach each other by the No. 1 electric push rod 77, thereby driving the two placement racks 8 to approach each other, squeezing and exhausting the bag. At the same time, the pressure plate 910 is pushed to squeeze and exhaust the bag by extending the No. 2 electric push rod 99. At the same time, the baffle at the end of the placement rack 8 and the pressure plate 910 of the placement rack 8 itself are used to limit the five sides of the bag, thereby ensuring the stability of the bag placement during the exhaust process and improving the exhaust stability. The gas discharge situation in the bag is monitored by the industrial camera 5. When the image information collected by the industrial camera 5 is determined by the industrial control system inside the human-computer interface 10 to be the completion of the exhaust of the bag, the No. 1 electric push rod 77 and the No. 2 electric push rod 99 are extended to complete the preparation of the nutrient solution.
