Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies technology, and in particular to an enteral nutrition solution warmer. Background Technology
[0002] Currently, devices for delivering nutrient solutions into the gastrointestinal tract generally use infusion tubing with a funnel, which is inserted into the gastrointestinal tract, and then the nutrient solution in the nutrient bag is delivered through the tubing.
[0003] When nutrient solutions are delivered via tubing, the temperature can be unbearable for humans due to weather conditions. To extend the heating of the nutrient solution, a heater is typically attached to the tubing. However, existing heaters are generally limited in function, have poor thermal conductivity, easily cause heat loss, resulting in poor heating performance. Furthermore, they lack temperature control and alarm functions. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] To address the issues of heaters having limited functionality, poor thermal conductivity leading to heat loss, poor heating effect, inability to control temperature, and lack of alarm prompts.
[0006] (2) Technical solution
[0007] The technical solution of this utility model is as follows: an enteral nutrition solution warmer, including a warmer body, a heating bottom plate, a heating top plate, a heating wire, a wire, a temperature control component, and a power plug. The heating bottom plate is located below the warmer body, and the heating top plate is hinged above the heating bottom plate. A heating wire is installed in the recessed part of the heating top plate. The heating wire has a corrugated structure. One end of the heating wire is connected to the wire, and the other end of the wire has an integrally formed power plug. A temperature control component is installed inside the heating top plate. When the infusion tube is placed between the heating bottom plate and the heating top plate, the abutment block on one side of the limiting plate is pressed against the position of the infusion tube under the compression of the spring. A temperature sensor is installed at the contact position between the abutment block and the infusion tube to facilitate the heating control of the nutrient solution in the infusion tube. The temperature of the heating wire is adjusted by operating the control panel. When the nutrient solution in the infusion tube is delivered, the pressure sensor value changes and sends a signal to the alarm light, which serves as an indication. The device has good performance.
[0008] Furthermore, the temperature control assembly includes a pressure sensor, a spring, a limit plate, a stop block, a temperature sensor, an alarm light, and a control panel. Pressure sensors are installed in blind slots at both ends of the heating upper slot. The pressure sensors are connected to springs located within the heating upper slot. A limit plate is installed at one end of the spring. A stop block is installed on the surface of the limit plate away from the limit plate, with one end extending to the outside of the heating upper slot. A temperature sensor is installed on the surface of the stop block. Alarm lights are installed on both ends of the heating upper slot, and a control panel is installed on the surface of the heating upper slot. The temperature sensor is connected to the control panel via signal transmission, and the control panel is connected to the alarm light via signal transmission. A temperature control component is installed. The infusion tube is placed between the heating bottom block and the heating top block. Under the compression of the spring, the abutment block on one side of the limiting plate is pressed towards the position of the infusion tube. A temperature sensor is installed at the contact position between the abutment block and the infusion tube to facilitate the heating control of the nutrient solution in the infusion tube. The temperature of the heating wire is adjusted by operating the control panel. When the nutrient solution in the infusion tube is delivered, the pressure sensor value changes and sends a signal to the alarm light, which serves as an indication. The system is effective.
[0009] Furthermore, a heat-conducting plate is installed on the concave surface of the heating tank block, which can improve the heat conduction efficiency of the heating wire, making the heating of the nutrient solution infusion tube more rapid and uniform, and improving the heating efficiency of the nutrient solution.
[0010] Furthermore, a base is installed on the bottom surface of the heating upper slot block, and adhesive parts are provided on the bottom surface of the base to facilitate fixing the main body of the heater to the patient's body part, resulting in good performance.
[0011] Furthermore, a speaker is installed on the surface of the heating tank block. The speaker transmits signals to the pressure sensor. When the nutrient solution inside the infusion tubing is delivered, the pressure sensor value changes. At this time, the pressure sensor sends a signal to the speaker, thereby serving as a warning.
[0012] Furthermore, one end of the wire is also equipped with another type of connector, a USB connector, which can improve the flexibility of use.
[0013] Furthermore, a fixed plate is rotatably mounted in a groove on the surface of the upper heating plate. A rubber strip is installed on the surface of the fixed plate and is engaged in a limiting groove on the surface of the lower heating plate. After the upper heating plate and the lower heating plate are rotated and come into contact, the rubber strip is engaged in the limiting groove by rotating the fixed plate, thereby locking the upper heating plate and the lower heating plate. This design is simple and convenient to open and close.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the infusion tube is placed between the heating bottom block and the heating upper block. A heat-conducting plate is installed on the concave surface of the heating upper block, which can improve the heat conduction efficiency of the heating wire, making the heating of the nutrient solution infusion tube more rapid and uniform, and improving the heating efficiency of the nutrient solution. Under the compression of the spring, the abutment block on one side of the limiting plate is pressed towards the position of the infusion tube. A temperature sensor is installed at the contact position between the abutment block and the infusion tube to facilitate the heating control of the nutrient solution inside the infusion tube. The temperature of the heating wire can be adjusted through the control panel. When the nutrient solution inside the infusion tube has been delivered, the pressure sensor value changes and sends a signal to the alarm light, providing an indication effect.
