Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to an intelligent nutrient solution warming device. Background Technology
[0002] In current clinical practice, enteral nutrition pumps and infusion pumps are widely used. These devices can provide convenience for patients and medical staff to a certain extent and solve some problems. However, existing equipment generally has some shortcomings. Specifically, most enteral nutrition pumps and infusion pumps cannot provide heat preservation or heating functions. Although a very small number of enteral nutrition pumps are equipped with external heating tubes, these heating tubes cannot precisely regulate the temperature of the enteral or parenteral nutrition solution.
[0003] When the temperature of enteral nutrition solution is low, it may cause diarrhea in patients; while low temperature of parenteral nutrition solution may cause vasospasm, chills, and hypothermia. Furthermore, existing external heating tubes have the following problems: First, they cannot precisely control the temperature, failing to meet the individual temperature tolerance needs of different patients; second, the surface temperature of the external device is high, easily causing burns to patients, and there is a fire risk when it comes into contact with fabric, thus requiring it to be placed far from the patient, causing the nutrition solution to cool down before entering the patient's body; third, the external device cannot heat immediately or quickly adjust the liquid temperature; finally, the external tubes are generally too long, which not only affects the operation of medical staff at the bedside but also causes inconvenience for patients to carry. Utility Model Content
[0004] To address the aforementioned technical problems, this invention designs an intelligent nutrient solution warming device. The device integrates an instant heating component, which, in conjunction with a high-power heating rod and a threaded water pipe design, can raise the nutrient solution to the ideal temperature within seconds. Furthermore, the outer shell of the device is made of high-performance heat-insulating material to prevent burns to the patient, while also ensuring the device is as close to the patient's body as possible to prevent the fluid from cooling during infusion due to the long infusion tubing. In addition, the device is equipped with adapters of different diameters, allowing connection to nutrient tubing of varying diameters depending on the application scenario, thus improving the device's flexibility.
[0005] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: an intelligent nutrient solution heat preservation device, comprising: a component compartment, a control panel, an instant heating component, and an electrical control component; the instant heating component is fixedly disposed inside the component compartment; the electrical control component is electrically connected to the instant heating component; and the control panel is fixedly disposed outside the component compartment.
[0006] Furthermore, the instant heating assembly includes: a heating rod, a glass tube, a threaded ring, a plug, a water inlet pipe, a water outlet pipe, and a temperature control probe; the heating rod is fixedly disposed inside the glass tube; the threaded ring is sleeved and fixedly disposed outside the heating rod; the plug is fixedly disposed at both ends of the glass tube; the water inlet pipe is fixedly connected to one end of the plug; the water outlet pipe is fixedly connected to the other end of the plug; the temperature control probe is connected to the water inlet pipe and the water outlet pipe respectively.
[0007] Furthermore, the threaded ring is fitted between the glass tube and the heating rod, which can ensure that the nutrient solution flows in a spiral manner inside the glass tube;
[0008] Furthermore, adapters are fixedly installed at the top and bottom of the component compartment; the adapters have a structure that is wider at the bottom and narrower at the top, which can be adapted to connect the device to nutrient pipes of different diameters.
[0009] Furthermore, the electrical control component adopts PID closed-loop control, which can adjust the heating rod power in real time according to the inlet and outlet water temperatures of the device to ensure heating accuracy;
[0010] Furthermore, the component compartment is made using polyurethane as the substrate.
[0011] The beneficial effects of this utility model are:
[0012] This invention discloses an intelligent nutrient solution warming device. Firstly, through the high-power heating rod of the instant heating component and the design of the threaded water flow pipe, the nutrient solution can be rapidly heated to the ideal temperature in a short time, greatly improving heating efficiency and ensuring that patients can receive nutrient solution at the appropriate temperature in a timely manner. This is particularly important for temperature-sensitive nutrient solution infusion scenarios, effectively preventing patient discomfort or poor infusion effects due to excessively low nutrient solution temperature. Secondly, the device's outer shell is made of high-performance heat-insulating material, which not only effectively prevents burns to patients during operation but also allows the device to be as close to the patient's body as possible, thereby reducing the length of the infusion tubing. This effectively prevents the nutrient solution from cooling due to contact with the external environment in a long infusion tubing, ensuring that the nutrient solution remains within the ideal temperature range during infusion, further improving the safety and effectiveness of the infusion. Furthermore, the device is equipped with adapters of different diameters, a design that greatly improves the device's flexibility and versatility. It can be easily and quickly connected to feeding tubes of different diameters to suit various usage scenarios and needs, making this device widely applicable in multiple medical settings without the need for additional adapters or conversion devices. This provides great convenience for medical staff and also reduces medical costs. Finally, the electrical control components employ PID closed-loop control technology, which can adjust the heating rod power in real time according to the inlet and outlet water temperatures, thereby ensuring heating accuracy. This precise temperature control method ensures that the temperature of the nutrient solution remains within the set range, further improving the safety and reliability of infusion and providing strong support for patient treatment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1
[0021] This utility model discloses an intelligent nutrient solution heat preservation device, referenced Figures 1 to 2 It includes: component compartment 1, control panel 2, instant heating component 3, and electrical control component 4. The instant heating component 3 is securely installed inside the component compartment 1, while the electrical control component 4 is electrically connected to the instant heating component 3, ensuring precise control of the heating process. The control panel 2 is fixed to the outside of the component compartment 1 for convenient operation and monitoring by the user.
[0022] The instant heating component 3 is the core part of this device, consisting of a heating rod 301, a glass tube 302, a threaded ring 303, a plug 304, a water inlet pipe 305, a water outlet pipe 306, and a temperature control probe 307. The heating rod 301 is fixedly installed inside the glass tube 302, while the threaded ring 303 is fitted over the heating rod 301 and fits tightly with the glass tube 302. Plugs 304 are fixedly installed at both ends of the glass tube 302, and the water inlet pipe 305 and water outlet pipe 306 are connected to the plugs 304 at both ends, forming a complete fluid channel. The temperature control probe 307 is connected to both the water inlet pipe 305 and the water outlet pipe 306 to monitor the temperature changes of the nutrient solution in real time.
[0023] The overfitting of the threaded ring 303 ensures that the nutrient solution flows in a spiral manner within the glass tube 302. This spiral flow design greatly increases the contact area and contact time between the nutrient solution and the heating rod 301, thereby significantly improving heating efficiency and enabling the nutrient solution to quickly reach the ideal temperature in a short time.
[0024] Adapters 101 are fixedly installed at the top and bottom of component compartment 1. These adapters 101 adopt a special structure that is wider at the bottom and narrower at the top. This structural design allows the adapters 101 to adapt to nutrition tubes of different diameters, thereby greatly improving the flexibility and versatility of the device. Whether it is a thick or thin tube, it can be easily connected to this device to meet the usage needs of different medical scenarios.
[0025] The electrical control component 4 employs PID closed-loop control technology. This control method can adjust the power of the heating rod 301 in real time according to the temperature of the inlet and outlet water of the device. Through precise temperature feedback and control algorithms, PID closed-loop control can ensure the accuracy of the heating process, keeping the temperature of the nutrient solution within the set range, thereby providing patients with stable and reliable temperature protection.
[0026] Finally, the component compartment 1 of this device is made of polyurethane as the base material. Polyurethane has excellent thermal insulation properties, which can effectively prevent heat transfer to the outside while ensuring the heating efficiency inside the device, thus avoiding burns to patients during operation. In addition, polyurethane also has good mechanical properties and corrosion resistance, which can ensure the stability and reliability of the device during long-term use.
[0027] The working principle and usage procedure of this device are as follows:
[0028] In terms of working principle, the core of the device is the instant heating component 3, whose internal heating rod 301 serves as the main heat source, converting electrical energy into heat energy to heat the nutrient solution inside the glass tube 302. The ingenious design of the threaded ring 303 causes the nutrient solution to flow in a spiral pattern within the glass tube 302. This flow not only increases the contact area between the nutrient solution and the heating rod 301 but also extends the contact time, thus achieving a rapid and uniform heating effect. Temperature control probes 307 are connected to the inlet pipe 305 and the outlet pipe 306 respectively, monitoring the temperature changes of the nutrient solution in real time and feeding this data back to the electronic control component 4. The electronic control component 4 employs PID closed-loop control technology, adjusting the power of the heating rod 301 in real time according to the temperatures of the inlet and outlet water to ensure the accuracy and stability of the heating process, keeping the temperature of the nutrient solution consistently within the ideal range.
[0029] In terms of usage, the nutrient solution is first introduced into the device through the inlet pipe 305. At this time, the user can set the desired nutrient solution temperature via the control panel 2. After the device is started, the heating rod 301 begins to work, heating the nutrient solution in the glass tube 302. During the heating process, the temperature control probe 307 continuously monitors the temperature and transmits the data to the electronic control component 4. Based on the difference between the set temperature and the actual monitored temperature, the electronic control component 4 adjusts the power of the heating rod 301 in real time using a PID closed-loop control algorithm to achieve precise temperature control. Once the nutrient solution reaches the set temperature, it flows out of the device through the outlet pipe 306 and connects to the infusion tubing at the patient's end for infusion. Because the component compartment 1 is made of polyurethane material, it has excellent heat insulation properties, effectively preventing burns to the patient while allowing the device to be close to the patient's body, reducing the length of the infusion tubing and preventing the nutrient solution from cooling during infusion. Furthermore, the adapter interface 101 at the top and bottom of the component compartment 1 allows the device to adapt to nutrient tubing of different diameters, improving the device's flexibility and versatility, and facilitating its use in various medical scenarios.
