Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical products, in particular to a spiral trachea with a heating function. Background Art
[0002] When using a non-invasive ventilator in winter, the patient's exhaled gas will form condensed water on the inner wall of the ventilator's trachea. In order to eliminate the condensed water, the prior art includes directly laying a heating wire inside the ventilator's trachea or injecting the heating wire into the spiral ribs on the outer wall of the ventilator's trachea.
[0003] As for the method of directly laying out the heating wire inside the ventilator trachea, since the heating wire is directly arranged inside the pipeline, high requirements are placed on the biological and chemical properties of the heating wire, which will increase the cost of the product.
[0004] For the means in the spiral ribs on the outer wall of the ventilator trachea, since the heating wire is injected inside the rib position of the pipeline, the surface temperature of the pipeline is high and it is easy to exceed the standard and scald the patient, and condensation water is easy to generate when the temperature difference between the inside and outside of the pipeline is large.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0021] Reference Figures 1 to 3 The utility model provides a spiral air tube with a heating function, the spiral air tube comprises a pipe 1, the pipe 1 comprises: an inner layer 11, an intermediate layer 12 and an outer layer 13; the inner layer 11 is made of a biocompatible material; the intermediate layer 12 is a heating coating coated on the outer wall of the inner layer 11; the outer layer 13 is coated on the heating coating and is made of a heat-insulating material.
[0022] Among them, the biocompatible material is thermoplastic elastomer; the thermal insulation material is a polymer material that can withstand high temperatures of 1000°C.
[0023] The heating coating applied on the outer wall of the inner layer 11 can evenly heat the medium flowing in the inner layer 11 according to the needs, prevent the patient's exhaled gas from forming condensed water inside it, and also prevent the condensed water from being generated due to the large temperature difference between the inner and outer walls of the pipe 1; in addition, since the heating coating is applied on the outer wall of the inner layer 11, the requirements for the biological and chemical properties of the heating coating are reduced, and the product cost is reduced. In addition, the outer layer 13 made of heat-insulating material can prevent the heating coating from overheating and scalding the patient, protecting the patient's safety.
[0024] The overall heating area of the inner layer 11 of the pipe 1 by the heating coating is also greater than the heating area of the heating wire in the prior art.
[0025] Reference Figure 2 The spiral air pipe further comprises: a spiral rib 2 spirally arranged on the outer layer 13 of the pipe 1. The spiral rib 2 can reduce the risk of collapse of the threaded pipe.
[0026] In this embodiment, the spiral air tube further includes: an electrode structure, and the electrode structure passes through the outer layer 13 and is connected to the middle layer 12 .
[0027] In actual use, the electrode structure connected to the heating coating is connected to the respiratory device to provide power. One end of the pipeline 1 is connected to the respiratory device, and the other end is connected to the patient-end product. When the gas passes through the pipeline 1, if the temperature sensor detects that the gas temperature in the pipeline 1 is lower than the set temperature, the respiratory device provides current to the middle layer 12 to start heating. When the temperature reaches the set temperature, the heating is stopped, and the inner layer 11 conducts the heat to the internal gas of the pipeline 1 to achieve the heating effect. Since the outer layer 13 is an insulating layer, the heat will be stored inside the pipeline 1 and the influence of the external temperature on the inner channel of the pipeline, such as cold air, will not be generated due to the impact of the cold and hot temperatures inside and outside. Condensation water will not be generated. In addition, the insulation temperature also reduces the risk of scalding the patient due to excessive pipeline temperature.
