Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to a parenteral nutrition solution preparation system. Background Technology
[0002] Parenteral nutrition support is an important part of clinical treatment, providing nutritional support to patients who cannot obtain nutrition through the gastrointestinal tract or whose nutrition intake is insufficient, through intravenous infusion of nutritional solutions.
[0003] Currently, the preparation of parenteral nutrition solutions mainly relies on manual operation. Medical staff need to memorize the order in which various nutrient solutions, such as glucose, fat emulsion, amino acids, electrolytes, and vitamins, are added. The process is cumbersome and prone to errors. If the order of addition is incorrect, it may affect the stability of the nutrient solution and the patient's treatment outcome. In addition, due to the numerous and complicated preparation steps, manual operation is inefficient. One person can only prepare one bag of parenteral nutrition solution at a time, resulting in a long preparation time per session, which is difficult to meet the needs of a large number of patients in clinical practice. Summary of the Invention
[0004] This application provides a parenteral nutrition solution preparation system to solve the problems of cumbersome, error-prone, and time-consuming manual drug preparation processes in related technologies, which are difficult to meet the needs of patients.
[0005] This application discloses a parenteral nutrition solution preparation system, comprising: A pumping device having multiple pipe interfaces and at least one pumping outlet, wherein the pipe interfaces are used to connect to different parenteral nutrition drug injection solutions; A mixing container, which is connected to the pump outlet, and is provided with a receiving cavity for containing the mixed parenteral nutrition drug injection solution; A detection device, which is connected to the pumping device, is used to detect the nutrient solution pumping dosage at each pipe interface. In addition, a control device is connected to the pumping device and the detection device. The control device is preset with multiple nutrient solution addition sequences and preset dosages. The control device opens the pipeline interface based on the addition sequence of multiple parenteral nutrition drug injections and closes the pipeline interface based on the detection device.
[0006] In one embodiment, the number of pump outlets corresponds to the number of pipe interfaces, and multiple pump outlets are all connected to the mixing container. The pumping device includes: A peristaltic pump is provided with multiple pumping channels, and the two ends of a single pumping channel form the pipe interface and the pumping outlet, respectively. In addition, there are infusion pipelines, which are set according to the number of pumping channels, and each pumping channel is provided with one infusion pipeline. The detection device is connected to multiple pumping channels and is used to detect the nutrient solution pumping dosage of each pumping channel.
[0007] In one embodiment, the detection device includes: A speed sensor is used to detect the rotational speed of each of the pumping channels.
[0008] In one embodiment, a parenteral nutrition solution preparation system further includes: A shaking device is provided, on which the mixing container is placed, and the shaking device is connected to the control device and is used to shake the mixing container.
[0009] In one embodiment, the oscillation device includes: A support platform, the surface of which is formed with an oscillating station for placing the mixing container; And an eccentric motor, which is connected to the support platform.

[0015] The beneficial effects of the technical solution provided in this application include: the control device has multiple pre-set mixed nutrient solution configuration schemes. When preparing parenteral nutrition solutions, the configuration scheme for this mixed nutrient solution is first selected. The control device opens different pipe interfaces according to the order of nutrient solution addition and pumps the corresponding nutrient solution into the mixing container for mixing. The pumping dose of each nutrient solution is detected by the detection device. The control device opens pipe interfaces based on the order of nutrient solution addition. When the preset dose is equal to the pumping dose, the control device closes the corresponding pipe interface and opens the next pipe interface in sequence until the mixing of multiple nutrient solutions is completed.
[0016] This application provides a parenteral nutrition solution preparation system. Because it uses a control device to sequentially open the corresponding pipe interfaces of the pumping device according to the preset order of adding multiple nutrient solutions and the preset dosage, and closes the corresponding pipe interfaces based on the detection device, it can complete the mixing of multiple nutrient solutions without the need for manual sequential addition of nutrient solutions. Therefore, it solves the problems of cumbersome, error-prone and time-consuming manual drug preparation operations in related technologies, which are difficult to meet the needs of patients.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] This application provides a parenteral nutrition solution preparation system that solves the problems of cumbersome, error-prone, and time-consuming manual drug preparation processes in related technologies, which are difficult to meet the needs of patients.
[0021] Reference Figure 1 This application discloses a parenteral nutrition solution preparation system, which includes a pumping device 1, a mixing container 2, a detection device, and a control device 3. The pumping device 1 is provided with multiple pipe interfaces 11 and at least one pumping outlet 12. The multiple pipe interfaces 11 are respectively used to connect different parenteral nutrition drug injection solutions 4, so that the nutrient solutions in the multiple different parenteral nutrition drug injection solutions 4 can be squeezed out through the pumping outlet 12 of the pumping device 1. The mixing container 2 is connected to the pumping outlet 12, and the pumping device 1 pumps multiple different nutrient solutions into the mixing container 2 through the pumping outlet 12. The detection device is connected to the pumping device 1 and is used to detect the pumping dosage of the parenteral nutrition drug injection solutions 4 connected to each pipe interface 11. The control device 3 is connected to the pumping device 1 and the detection device, and the control device 3 is preset with the addition order of multiple parenteral nutrition drug injection solutions 4. The system allows for the selection of nutrient solution addition sequences and preset dosages. During use, the pipe interface 11 on the pumping device 1 is opened according to the selected nutrient solution addition sequence. At this time, the detection device detects the nutrient solution pumping dosage at the pipe interface 11. When the nutrient solution pumping dosage reaches the preset dosage, the pipe interface 11 is closed. Then, the next pipe interface 11 is opened according to the nutrient solution addition sequence until all nutrient solutions are added. The operator only needs to set the addition sequence and preset dosage of various nutrient solutions in the control device 3 in the early stage. When using the system, the operator selects the nutrient solution addition sequence and preset dosage for this use, and the parenteral nutrition solution can be prepared in the mixing container 2 without manual addition. This simplifies the work process, greatly saves medication preparation time, and solves the problems of cumbersome, error-prone, and time-consuming manual medication preparation in related technologies, which are difficult to meet the needs of patients.
[0022] In practical use, the mixing container 2 can be a 3-liter bag, facilitating subsequent medical procedures for healthcare personnel. The control device 3 features multi-device linkage capabilities, connected via a wireless network. It includes a visual operating interface, allowing a single healthcare worker to monitor all devices centrally. In practice, the control device 3 can also be connected to multiple pumping devices 1, enabling one device 3 to manage multiple pumping devices 1 and handle various parenteral nutrition solution preparation procedures. The operating interface allows real-time viewing of each device's preparation progress, operating status, and other information, as well as remote operation such as starting, pausing, and adjusting parameters, significantly improving work efficiency.
[0023] In one embodiment of this application, the number of pump outlets 12 and pipe interfaces 11 are correspondingly arranged, and multiple pump outlets 12 are connected to the mixing container 2. In this embodiment, the pumping device 1 specifically uses a peristaltic pump and infusion tubing. The peristaltic pump is provided with multiple pumping channels, and the two ends of a single pumping channel form a pipe interface 11 and a pump outlet 12, respectively. Each pumping channel is provided with a rotating motor, and each rotating motor has an infusion tubing passing through it. One end of the infusion tubing located at the pipe interface 11 is used to connect to the parenteral nutrition drug injection solution 4, and the other end located at the pump outlet 12 is used to connect to the mixing container 2. After the peristaltic pump is turned on, the motor in the pumping channel rotates and squeezes the infusion tubing to realize the delivery of the nutrient solution. By setting up the peristaltic pump and infusion tubing, separate infusion channels can be provided for various different nutrient solutions. After a single parenteral nutrition solution is prepared, the pumping device 1 can be cleaned by replacing the infusion tubing, which meets medical hygiene standards and is easy to clean. When connecting the infusion tubing to the parenteral nutrition drug injection solution 4 and the mixing container 2, the tubing connection should be made without dead angles to avoid the accumulation of various nutrient solutions at the connection point and reduce the risk of blockage.
[0024] To improve the accuracy of nutrient solution delivery, a high-precision quantitative peristaltic pump can be used. The peristaltic pump promotes liquid flow within the infusion tubing through compression. Under constant pressure, the rotational speed within the pumping channel is directly proportional to the amount of liquid flowing through the tubing. Specifically, in this embodiment, the detection device includes a speed sensor installed within the pumping channel to detect the rotational speed of the motor within the channel. By detecting the rotational speed and number of revolutions of the motor, precise control of the nutrient solution delivery dosage can be achieved. For example, for components requiring precise proportions, such as amino acids and glucose, the corresponding motor speed and number of revolutions can be preset in the control device 3, allowing for the delivery of a specific volume of solution with minimal error, thus ensuring the accuracy of the prepared concentration.
[0025] In other embodiments of this application, a hydraulic pump can also be used as the pumping device 1. The hydraulic pump has a mixing chamber connected to a pipe interface 11 and a pumping outlet 12 connected to the mixing chamber. Valves are installed at both the pipe interface 11 and the pumping outlet 12. Each pipe interface 11 is connected to the parenteral nutrition drug injection solution 4 through a pipe. In actual use, the control device 3 sequentially opens the valves at the pipe interfaces 11 to allow different nutrient solutions to enter the mixing chamber, allowing for initial mixing of the various nutrient solutions. After the addition of multiple nutrient solutions, the valve at the pumping outlet 12 is opened, and the solution enters the mixing container 2 through the pumping outlet 12. In this embodiment, the hydraulic pump must be cleaned according to hygiene standards after each use to ensure the cleanliness of the mixing chamber and valves. In this embodiment, a liquid level sensor can be used as the detection device. It is installed in the mixing chamber and determines the pumping dosage of the nutrient solution in the mixing chamber by detecting the liquid level height.
[0026] To provide real-time reminders to medical staff regarding the dosage of parenteral nutrition solutions, one embodiment of this application includes an additional voice prompt system connected to the control device 3. This system broadcasts information based on a preset order and dosage of parenteral nutrition solution additions within the control device 3. Specifically, in actual use, the control device 3 can broadcast the pipeline interface 11 to be opened according to the preset order of parenteral nutrition solution additions, allowing the addition of the corresponding connected parenteral nutrition solution. Furthermore, to further improve the accuracy of the overall configuration device, the voice prompt system can be configured to continuously broadcast the types of parenteral nutrition solutions in that order until the control device 3 receives the parenteral nutrition solution pumping dosage from the detection device and it reaches the preset dosage. For example, in the preparation of a parenteral nutrition solution, amino acid injection solution needs to be added first, followed by glucose injection solution. The voice prompt system first prompts "Please add amino acid injection solution." Only when the amino acid pumping dosage transmitted by the detection device reaches the preset dosage in the control device 3 is the control device 3 considered to have completed the pumping of amino acid injection solution and sends a signal to the voice prompt system. The voice prompt system then continues to prompt "Please add glucose injection solution," and so on, ensuring the accuracy of the medication addition order.
[0027] Since the various nutrient solutions are placed in the mixing container 2, medical staff need to shake the mixing container 2 to ensure thorough mixing. To further reduce the workload of medical staff, this application also includes a shaking device. The mixing container 2 is placed inside the shaking device, which is connected to the control device 3 and used to shake the mixing container 2. In actual use, after the control device 3 pumps the various nutrient solutions into the mixing container 2 in a preset sequence, the control device 3 activates the shaking device to shake the mixing container 2, thereby completing the mixing of the various nutrient solutions within the mixing container 2.
[0028] More specifically, in one embodiment of this application, the oscillation device includes a support platform and an eccentric motor. The surface of the support platform forms an oscillation station for placing the mixing container 2, allowing the mixing container 2 to be placed on the support platform. The output end of the eccentric motor is connected to the support platform. Turning on the eccentric motor drives the support platform to generate high-frequency, small-amplitude oscillations, thereby promoting thorough mixing of the various nutrient solutions in the mixing container 2 during the oscillation process. The frequency and amplitude of the eccentric motor's oscillation can be intelligently adjusted within the control device 3 according to the actual composition and characteristics of each nutrient solution. For example, for easily precipitated fat emulsions, the oscillation frequency and amplitude can be appropriately increased to ensure that they are evenly dispersed in the nutrient solution.
[0029] Furthermore, this application also includes a constant temperature chamber 5, which is connected to the control device 3 and has a constant temperature cavity 51 for accommodating the mixing container 2. The storage temperature of the constant temperature chamber 5 is controlled within a suitable range according to the actual needs of the nutrient solution, preventing changes in the solubility of the nutrient solution in the mixing container 2 due to temperature variations, thus preventing precipitation. Furthermore, a pressure sensor can be added to the constant temperature chamber 5 to monitor the pressure inside the chamber 5 in real time, maintaining stable pressure within the container and preventing pressure fluctuations from affecting the stability of the nutrient solution. In embodiments equipped with a shaking device, the shaking device can be placed inside the constant temperature chamber 5 to achieve shaking of the mixing container 2 under constant temperature and pressure conditions.
