Silica gel heating tube device for blood transfusion and infusion

Abstract

The invention relates to a silica gel heating tube device for blood transfusion and infusion, which comprises a silica gel heating tube, the silica gel heating tube is provided with an inner cavity, an opening is formed in the side wall of the silica gel heating tube in the length direction of the silica gel heating tube, and the opening is communicated with the inner cavity of the silica gel heating tube and used for embedding a blood transfusion and infusion tube into the inner cavity of the silica gel heating tube; an electric heating wire used for heating is embedded in the pipe wall of the silica gel heating pipe, a temperature sensor is fixedly connected to the inner wall of the silica gel heating pipe, the temperature sensor is adjacent to one electric heating wire, and the electricheating wire is the nearest electric heating wire. The nearest electric heating wire is connected with a metal wire in series, the length of the metal wire is more than three times that of the temperature sensor, and the temperature sensor faces the middle of the metal wire. The air gap between the temperature sensor and the blood transfusion and infusion tube is prevented from being enlarged inuse, and the temperature sensor is prevented from being affected by the electric heating wire.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Hospitals often transfuse blood or fluids for patients. If the temperature of the blood or medicinal liquid input into the human body is too low, it will bring pain to the patient, and even cause the patient to produce adverse reactions. Therefore, it is necessary to warm the blood or the liquid medicine, which requires the use of the silicone heating tube 1 . Such as figure 1 As shown, the inner cavity 3 of the silicone heating tube 1 is used to accommodate the blood transfusion tube. The side wall of the silicone heating tube 1 is provided with an opening 2 along the length direction of the silicone heating tube 1. When in use, the blood transfusion tube is inserted into the silicone heating tube through the opening 2. 1 of the lumen 3. A number of electric heating wires 4 (such as carbon fiber heating wires) are embedded in the inner wall of the si...

Problems solved by technology

But this technology has caused new problem again: the lead wire of temperature sensor 5 stretches into the inner cavity 3 of silicone heating tube 1, and the position of temperature sensor 5 and its lead in the inner cavity 3 of silicone heating tube 1 will be in the blood transfusion. Changes in the process may lead to an increase in the air gap between the temperature sensor 5 and the blood transfusion tube, resulting in the temperature sensor 5 not being able to accurately measure the temperature of the blood transfusion

[0006] Although the above-mentioned new problem is more accurate than the first defect, the measured temperature is relatively accurate, but there is still a possibility of large deviation, which will bring discomfort to the patient and is not conducive to controlling the temperature conditions of blood transfusion
