Description

Infusion tube heating device

technical field

The utility model belongs to the field of medical equipment, in particular to an intelligent heating device for infusion tubes.

Background technique

Infusion tubes include intravenous infusion tubes, nasogastric tubes, enteral nutrition infusion tubes, or blood product infusion tubes. Take nasogastric tubes as an example. Nasal feeding nursing and liquid feeding are usually performed for patients who are not eating, fasting after gastrointestinal surgery, or unconscious. The front end of the nasogastric tube is inserted into the stomach through the patient's nostril, and the back end is connected with the container containing liquid food, and the liquid food is pumped into the patient's stomach through a pump.

At present, most nasogastric tubes are not equipped with thermal insulation structure. Liquid food dissipates heat quickly, and the food tends to become cold. Once the cold food enters the gastrointestinal tract, it is easy to cause gastrointestinal cramps and other phenomena in patients, causing abdominal pain and diarrhea. Such complications are not only unfavorable for the rehabilitation of patients, but also increase the difficulty and workload of medical staff.

In order to solve the above technical problems, in the existing clinical practice, nasogastric tube manufacturers usually provide several simple heating clips when providing nasogastric tubes. Heating strips are arranged symmetrically on the inner sides of the two clips. Apply heat to the stomach tube. Heating is stopped after the power is cut off, so it can only be heated at one temperature, and the temperature cannot be monitored and adjusted at all.

In addition, in order to prevent the patient from touching it by mistake, the heating clip is generally arranged on the outlet pipe of the liquid food container, with a certain distance from the patient's nose. When the heated liquid food flows into the patient's body, part of the heat is usually lost, resulting in a low temperature of the liquid food flowing into the patient's body, causing damage to the patient's stomach.

Due to the obvious disadvantages of the heating clamp, other types of gastric tube heating devices have also appeared in the prior art, such as the Chinese utility model patents with the patent number CN204563268U and the patent number CN204972463U, which respectively disclose a heating device using circulating heating water and a heater. The gastric tube heating device for heating the gastric tube continuously heats the circulating water in the heating water pipe through the heater to ensure the constant temperature of the liquid food in the nasogastric tube. However, in actual application, this kind of device occupies a large area, and there is a risk of touching the heater at any time during clinical nursing applications in crowded wards, which is often inconvenient.
