Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly relates to a heat preservation device for enteral nutrition delivery. Background Art

[0002] Medical devices refer to instruments, equipment, apparatus, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. Medical devices include medical equipment and medical consumables, and their main purpose is mainly for the diagnosis, prevention, monitoring, treatment, or alleviation of diseases, etc. Clinically, in order to deliver enteral nutrition to the stomach of a patient, a nasogastric tube is generally inserted into the patient's nose first, and then a transfusion strip about 1 meter long (i.e., enteral nutrition infusion device) is connected between the enteral nutrition output device and the nasogastric tube. To ensure the comfort and safety of the patient, the temperature of enteral nutrition needs to be controlled between 38 - 42 degrees.

[0003] According to the Chinese patent number CN209564409U, a heat preservation device for enteral nutrition delivery is disclosed, including a heater for heating the infusion belt to 38 - 42 degrees and a housing with an infusion belt through hole; the heater is installed inside the housing. During the process of delivering enteral nutrition through the transfusion strip, the belt section is the key to controlling the temperature of enteral nutrition. Through the heating effect of the heater, the purpose of controlling the temperature between 38 - 42 degrees can be achieved, avoiding the external environmental temperature. However, the heater in the above heat preservation device is in direct contact with the infusion belt. When the nutrient being transported passes through the heater, it is not convenient to control the temperature of the nutrient, resulting in inconvenient use. For this reason, we propose a heat preservation device for enteral nutrition delivery. Summary of the Utility Model

[0021] The following will detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution for a heat preservation device for enteral nutrition delivery:

[0023] A heat preservation device for enteral nutrition delivery includes a machine shell 1. Inside the machine shell 1 is fixedly connected a heat preservation water tank 12. On the back of the heat preservation water tank 12 is provided an embedded groove 13. Inside the embedded groove 13 is provided a delivery pipe 6. On the upper surface of the machine shell 1 is fixedly connected a first temperature sensor 5, and the first temperature sensor 5 is in contact with the delivery pipe 6. On the front of the machine shell 1 is fixedly installed a control panel 11. Inside the heat preservation water tank 12 is provided a heating pipe 14. On the right side of the machine shell 1 is provided a refrigerator 10. The cold surface of the refrigerator 10 is arranged inside the heat preservation water tank 12, and the hot surface of the refrigerator 10 is arranged outside the machine shell 1 for convenient heat dissipation. Inside the heat preservation water tank 12 are provided a second temperature sensor 15 and a water level sensor 16. The control panel 11 is internally provided with a controller 18; specifically, the nutrition delivery pipe 6 is clamped into the embedded groove 13 in the heat preservation water tank 12. When the heating pipe 14 in the heat preservation water tank 12 heats the water, with the cooperation of the second temperature sensor 15, the water temperature is maintained within a certain temperature range, so that the nutrients passing through the delivery pipe 6 can reach the required temperature. When the water temperature rises, the cold surface of the refrigerator 10 can quickly cool the aqueous solution to the set temperature range;

[0024] In this embodiment, two support legs 2 are fixedly connected to the bottom surface of the casing 1, and a handle 9 is fixedly installed on the upper surface of the casing 1; two groups of fixing straps 7 are fixedly connected to the outer surface of the casing 1, and magic tapes are provided on the outer surface of each fixing strap 7. Specifically, the support legs 2 facilitate the support of the heat preservation device, the handle 9 can be used to move the heat preservation device, and the magic tapes on the fixing straps 7 can fix the heat preservation device on the hospital bed guardrail for convenient use.

[0025] In this embodiment, a water injection pipe 3 is fixedly communicated with the left side surface of the heat preservation water tank 12. One end of the water injection pipe 3 penetrates through the casing 1 and extends to the outside of the casing 1, and a sealing cover 4 is threadedly connected to the top end of the water injection pipe 3; an alarm 8 is fixedly installed on the upper surface of the heat preservation water tank 12, and a display screen 17 is provided on the front surface of the control panel 11; the first temperature sensor 5, the second temperature sensor 15 and the water level sensor 16 are all electrically connected to the controller 18 through wires, and the controller 18 is electrically connected to the alarm 8, the cooler 10, the heating pipe 14 and the display screen 17 through wires respectively. Specifically, water can be injected into the heat preservation water tank 12 through the water injection pipe 3. The first temperature sensor 5 is arranged at the outlet of the conveying pipe 6 to monitor the temperature of the nutrient. If the temperature of the nutrient exceeds the required temperature range, the heat preservation device starts the alarm 8 to give an alarm prompt to ensure the normal temperature of the nutrient transportation. The display screen 17 can display the water level and temperature.

[0026] The control mode of the present utility model is controlled by the controller 18. The control circuit of the controller 18 can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art, and the electrical components involved in the present utility model are all commonly used existing components. Therefore, the control mode and the circuit connection of the present utility model will not be explained in detail.

[0027] Working principle: When the heat preservation device is in use, the user first carries the heat preservation device to the use position through the handle 9, clips the nutrient delivery pipe 6 into the embedding groove 13 in the heat preservation water tank 12, and then fixes the heat preservation device on the hospital bed guardrail through the fixing strap 7. Water solution is injected into the heat preservation water tank 12 through the water injection pipe 3. When the heating pipe 14 in the heat preservation water tank 12 heats the water, with the cooperation of the second temperature sensor 15, the water temperature is kept within a certain temperature range, so that the nutrient passing through the conveying pipe 6 can reach the required temperature. When the water temperature rises, the cold surface of the cooler 10 can quickly cool the water solution to the set temperature range. At the same time, the first temperature sensor 5 is arranged at the outlet of the conveying pipe 6 to monitor the temperature of the nutrient. If the temperature of the nutrient exceeds the required temperature range, the heat preservation device starts the alarm 8 to give an alarm prompt to ensure the normal temperature of the nutrient transportation.
