Embodiment Construction

[0008] Example. The disposable heatable infusion set comprises an existing disposable infusion set, and is characterized in that a spiral heat exchanger is connected in series on the infusion pipeline of the infusion set. As shown in Figure 1, the spiral heat exchanger consists of a closed hollow cylinder 1, the lower part of the hollow cylinder 1 is provided with a water inlet pipe 2, and the upper part is provided with a water outlet pipe 3, and the hollow cylinder 1 is provided with a The positioning shaft is fixed with a helically coiled infusion tube 7 outside the positioning axis, and the infusion tube 7 leads out the liquid inlet pipe 8 from the top of the hollow cylinder 1 and the liquid outlet pipe 9 from the bottom of the hollow cylinder 1 . The positioning shaft can be made of a central shaft 5, spokes 4 arranged on the central shaft 5, and a mesh cylinder 6 fixed on the spokes 4 (as shown in Figure 1). The positioning shaft is a hollow shaft, which is used to fix ...

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable infusion set. Background technique [0002] Infusion is a common method of contemporary medical treatment. Disposable infusion sets are medical devices that must be used during infusion. Disposable infusion sets have many advantages, but it also has a major disadvantage that cannot be ignored, that is, it cannot heat the medicinal liquid it infuses. The normal body temperature of the human body is 37°C±0.5°C. If the cold medicinal solution with a temperature lower than this temperature is directly injected into the human body, the cold medicinal liquid will absorb the heat of the human body after entering the human body, thus causing cold stimulation to the patient. The lower the temperature of the liquid medicine, the faster the infusion speed will be, and the more severe the cold stimulation will be to the patient. Experience tells us that direct infusion of liquid medicine w...
