[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0029] The embodiment of the present application provides an insulation pipe for reducing the generation of condensed water. The generation of condensed water is reduced by means of an inner and outer two-layer tubular structure and threaded ribs with buried heating wires. The overall structure is simple and reliable, and the cost is low.

[0030] In order to achieve the above technical effects, the overall idea of ​​this application is as follows:

[0031] A thermal insulation pipe for reducing the generation of condensed water, the thermal insulation pipe comprising:

[0032] Internal supervisor 1;

[0033] An outer pipe 2 spirally wound outside the inner main pipe 1;

[0034] A threaded rib 3 is spirally wound around the outer side of the inner main pipe 1, and a heating wire is embedded in the threaded rib 3;

[0035] The thermal conductivity of the outer layer pipeline 2 is lower than the thermal conductivity of the inner layer main pipe 1 .

[0036] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 4 As shown, an embodiment of the present application provides a heat preservation pipe for reducing the generation of condensed water, the heat preservation pipe comprising:

[0038] Internal supervisor 1;

[0039] An outer pipe 2 spirally wound outside the inner main pipe 1;

[0040] A threaded rib 3 is spirally wound around the outer side of the inner main pipe 1, and a heating wire is embedded in the threaded rib 3;

[0041] The thermal conductivity of the outer layer pipeline 2 is lower than the thermal conductivity of the inner layer main pipe 1 .

[0042] In the embodiment of the present application, the generation of condensed water is reduced by using the inner and outer two-layer tubular structure and the threaded ribs with buried heating wires. The overall structure is simple, reliable and low-cost.

[0043] Specifically, the heat preservation tube is used as an important part of medical equipment such as nasal oxygen tubes and masks. The heated air-oxygen mixed high-concentration gas with a certain oxygen concentration can be delivered to the patient through the nasal oxygen tube or mask connected to the ventilator. The nasal oxygen tube is used as an interface to connect the respiratory gas source pipeline and the human body. This can improve the blood oxygen saturation concentration, increase the arterial oxygen partial pressure, ventilation function and reduce respiratory power consumption, and achieve the purpose of oxygen therapy for patients.

[0044] It should be noted that the traditional high-flow nasal oxygen cannula mainly consists of three parts: the nasal oxygen cannula air inlet end, the nasal oxygen cannula air supply end and the nasal oxygen cannula patient connection end. The nasal oxygen cannula air inlet end has: conversion joint, joint inner core, hanging rope; the nasal oxygen cannula patient connection end has: elbow joint, rotating ring, nasal oxygen cannula body, connection fixing buckle, headband, etc.; the nasal oxygen cannula supply end has: breathing tube, guide ring, etc.; the breathing tube of the nasal oxygen cannula air supply end commonly used in the market is generally a single-layer thin-walled winding tube, which is a layer of bottom film wrapped around a layer of threaded ribs;

[0045] The structure is too simple and the wall of the breathing tube is too thin, which will cause rapid heat loss. Therefore, when the air-oxygen mixture that has been heated and humidified passes through the breathing tube for too long at night or when the temperature is low in winter, condensed water will easily accumulate and affect the oxygen delivery process. When too much condensed water accumulates, it will enter the patient's nasal respiratory system through the breathing tube, causing difficulty in breathing and even life-threatening.

[0046] When patients need to use a ventilator connected to a mask or nasal oxygen tube and other medical devices for various reasons, there is a possibility that the patient may have difficulty breathing or even be in danger due to condensation in the breathing tube. The insulation tube provided in this application can solve the potential dangers of patients when using the above-mentioned medical devices to protect the basic rights and safety of patients.

[0047] Furthermore, the cross section of the outer layer pipeline 2 is bubble-shaped.

[0048] Furthermore, the outer layer pipeline 2 and the threaded rib 3 are coaxially and spirally wound around the outer side of the inner layer main pipe 1 .

[0049] Furthermore, the threaded rib 3 is located between the outer layer pipeline 2 and the inner layer main pipe 1 .

[0050] Furthermore, the heights of the outer layer pipeline 2 and the threaded rib 3 relative to the outer surface of the inner layer main pipe 1 are inconsistent.

[0051] Furthermore, the outer layer pipeline 2 and the threaded rib 3 are at the same height relative to the outer surface of the inner layer main pipe 1 .

[0052] Furthermore, the spacing distance between the outer layer pipelines 2 is configured so that an air layer is formed in the outer layer pipeline 2 when the heating wire of the threaded rib 3 is heated.

[0053] Based on the embodiment of the present application, a new three-layer thermal insulation breathing tube is provided to reduce the generation of condensation water. Since the heat transfer in the air is worse than the conduction effect in the solid, it can effectively solve the problem of heat transfer and diffusion of the gas flowing through the three-layer thermal insulation breathing tube when working, causing the temperature of the breathing tube to be too high, thereby scalding the patient's skin, and greatly reduce the condensation water generated by excessive use.

[0054] It should be noted that the technical solution of the embodiment of the present application also has the following technical details:

[0055] The thermal conductivity of the outer layer pipeline 2 is inconsistent with that of the inner layer main pipe 1, and the thermal conductivity of the outer layer pipeline 2 is lower than that of the inner layer main pipe 1;

[0056] The cross-sectional shape of the outer layer pipeline 2 is a bubble shape, and the cross section is similar to an ellipse or a circle;

[0057] The outer layer pipe 2 is spirally wound and coated on the outer side of the inner layer main pipe 1;

[0058] The height of the outer layer pipeline 2 is higher or lower than the height of the threaded rib 3 .
