Description

Spiral air pipe with heating function

Technical Field

The utility model relates to the field of medical products, in particular to a spiral air pipe with a heating function.

Background

When the noninvasive ventilator is used in winter, condensed water is formed on the inner wall of the air pipe of the ventilator due to gas exhaled by a patient, so that the condensed water is eliminated. The prior art has means of directly arranging heating wires inside the breathing machine air pipe or injecting the heating wires into spiral ribs on the outer wall of the breathing machine air pipe.

For the means of directly laying the heater wire inside the ventilator's trachea, because the heater wire is directly arranged inside the pipeline, the biological and chemical performance requirements for the heater wire are high, which can increase the cost of the product.

For the means in the spiral muscle on the breathing machine trachea outer wall, because the heater strip moulds plastics in pipeline muscle position inside, pipeline surface temperature is high, exceeds standard easily, scalds the patient, and produces the comdenstion water easily when the inside and outside difference in temperature of pipeline is big.

Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

Referring to fig. 1 to 3, the utility model provides a spiral pipe with a heating function, the spiral pipe comprises a pipeline 1, the pipeline 1 comprises an inner layer 11, an intermediate layer 12 and an outer layer 13, the inner layer 11 is made of a material with biocompatibility, the intermediate layer 12 is a heating coating coated on the outer wall of the inner layer 11, and the outer layer 13 is coated on the heating coating and made of a heat insulation material.

Wherein the biocompatible material is thermoplastic elastomer, the heat insulating material is polymer material, and can resist high temperature 1000 ℃.

The heating coating coated on the outer wall of the inner layer 11 can uniformly heat the medium flowing in the inner layer 11 according to the requirement, prevent the gas exhaled by a patient from forming condensed water in the inner part of the medium, and prevent the excessive temperature difference between the inner wall and the outer wall of the pipeline 1 from generating condensed water. And, the outer layer 13 made of heat insulation material can prevent the overheat of the heating coating from scalding a patient, so that the patient is protected.

The overall heating area of the inner layer 11 of the pipe 1 by the heating coating is also due to the heating area of the heating wires of the prior art.

Referring to fig. 2, the spiral pipe further includes a spiral rib 2 spirally disposed on an outer layer 13 of the pipe 1. The helical rib 2 can reduce the risk of collapse of the threaded pipe.

In this embodiment, the spiral pipe further comprises an electrode structure connected to the intermediate layer 12 through the outer layer 13.

When the pipeline 1 is used practically, the electrode structure connected with the heating coating is connected with breathing equipment to provide power, one end of the pipeline 1 is connected with the breathing equipment, and the other end is connected with a patient end product, when the gas passes through the pipeline 1, such as a temperature sensor detects that the temperature of the gas in the pipeline 1 is low to a set temperature, the breathing equipment supplies current to the middle layer 12 to start heating, the heating is stopped when the temperature reaches the set temperature, the inner layer 11 conducts heat to the gas in the pipeline 1 to achieve the heating effect, and because the outer layer 13 is a heat insulation layer, the heat can be stored in the pipeline 1 and the influence of the external temperature on the pipeline inner channel, such as cold air, cannot be caused by opposite flushing of the internal and external cold temperatures, condensate water phenomenon is generated, and in addition, the risk of scalding patients due to overhigh pipeline temperature is reduced due to the insulation temperature.
