Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a heat-insulating tube with a surface coating. Background Technology

[0002] In the medical field, oxygen therapy is one of the most commonly used treatments in clinical practice, and it is used to treat hypoxia caused by various reasons.

[0003] Inhaling high concentrations of oxygen increases the dissolved oxygen in the blood plasma, thereby improving tissue oxygenation and promoting metabolism. Common oxygen therapy methods include: nasal cannula and nasal oxygen therapy, face mask oxygen therapy, endotracheal tube oxygen therapy, electronic pulse oxygen therapy, mechanical ventilation, and hyperbaric oxygen therapy. Nasal cannulas and face masks, as medical equipment used in oxygen therapy, play a significant role in medical settings such as emergency rooms, operating rooms, general wards, and ICUs. They are used to alleviate hypoxia symptoms in patients with acute respiratory distress and maintain vital sign balance. Patients with chronic respiratory diseases such as asthma can also receive necessary oxygen support through nasal cannulas and face masks. They are also used for pre- and post-operative care, helping patients recover quickly and reducing postoperative complications. Furthermore, they can provide timely oxygen supplementation to reduce the impact of altitude sickness when entering high-altitude areas.

[0004] Therefore, to meet practical needs, a heat-insulating pipe with a surface coating is provided. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this application is to provide a heat-insulating pipe with a surface coating, which is heated by a heating wire outside the inner main pipe, thereby forming an air layer between the outer membrane and the inner main pipe, thereby reducing the generation of condensate. The overall structure is simple, reliable and low cost.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0029] This application provides a surface-coated heat-insulating pipe, which is heated by a heating wire outside the inner main pipe, thereby forming an air layer between the outer membrane and the inner main pipe, reducing the generation of condensate. The overall structure is simple, reliable, and inexpensive.

[0030] To achieve the aforementioned technical effects, the overall concept of this application is as follows:

[0031] A surface-coated insulation pipe, the insulation pipe comprising:

[0032] Internal supervisor 1;

[0033] A threaded rib 2 is spirally wound around the outside of the inner main tube 1, and a heating wire 3 is embedded in the threaded rib 2;

[0034] An outer diaphragm 4 covering the outer side of the inner main tube 1 and the threaded rib 2;

[0035] The thermal conductivity of the outer diaphragm 4 is lower than that of the inner main tube 1;

[0036] The threaded rib 2 is located between the outer diaphragm 4 and the inner main tube 1;

[0037] The spacing between the outer diaphragm 4 and the inner main tube 1 is configured such that when the heating wire 3 of the threaded rib 2 is heated, an air layer is formed between the outer diaphragm 4 and the inner main tube 1.

[0038] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0039] See Figures 1-5 As shown, this application embodiment provides a surface-coated heat-insulating pipe, the heat-insulating pipe comprising:

[0040] Internal supervisor 1;

[0041] A threaded rib 2 is spirally wound around the outside of the inner main tube 1, and a heating wire 3 is embedded in the threaded rib 2;

[0042] An outer diaphragm 4 covering the outer side of the inner main tube 1 and the threaded rib 2;

[0043] The thermal conductivity of the outer diaphragm 4 is lower than that of the inner main tube 1;

[0044] The threaded rib 2 is located between the outer diaphragm 4 and the inner main tube 1;

[0045] The spacing between the outer diaphragm 4 and the inner main tube 1 is configured such that when the heating wire 3 of the threaded rib 2 is heated, an air layer is formed between the outer diaphragm 4 and the inner main tube 1.

[0046] In this embodiment, heating is achieved by heating the inner tube with a heating wire outside, thereby forming an air layer between the outer diaphragm and the inner tube, reducing the generation of condensate. The overall structure is simple, reliable, and inexpensive.

[0047] Furthermore, the spacing between the threaded ribs 2 is equal.

[0048] Furthermore, the distance between the outer diaphragm 4 and the inner main tube 1 is equal.

[0049] Specifically, this insulated tube, as an important component of medical equipment such as nasal oxygen tubes and masks, can be connected to a ventilator via a nasal oxygen tube or mask to deliver a high-concentration gas mixture of heated air and oxygen to the patient. The nasal oxygen tube serves as an interface to connect the respiratory gas source pipeline to the human body, thereby improving blood oxygen saturation, increasing arterial blood oxygen partial pressure, improving ventilation function, and reducing respiratory power consumption, thus achieving the goal of oxygen therapy for the patient.

[0050] It should be noted that traditional high-flow nasal oxygen cannulas mainly consist of three parts: the nasal oxygen cannulas inlet, the nasal oxygen cannulas air supply end, and the nasal oxygen cannulas patient connection end. The nasal oxygen cannulas inlet includes: a conversion connector, a connector inner core, and a hanging cord; the nasal oxygen cannulas patient connection end includes: a bend connector, a rotating ring, the nasal oxygen cannulas body, a connecting and fixing buckle, and a headband; the nasal oxygen cannulas air supply end includes: the breathing tubing, a guide ring, etc. Among them, the breathing tubing of the air supply end of nasal oxygen cannulas commonly used in the market is generally a single-layer thin-walled spiral tube, which consists of a bottom membrane wrapped with a layer of threaded ribs.

[0051] An overly simplistic breathing tubing design with thin walls leads to rapid heat loss. This causes condensation to accumulate when the heated and humidified air-oxygen mixture passes through, especially during prolonged nighttime use or in cold winter temperatures, affecting oxygen delivery. Excessive condensation can then enter the patient's nasal respiratory system, causing breathing difficulties and potentially life-threatening situations.

[0052] Patients who need to use ventilators connected to medical devices such as masks or nasal cannulas for various reasons may experience breathing difficulties or even danger due to condensation in the breathing tubing. The insulated tubing provided in this application can solve the potential dangers for patients when using these medical devices, thereby protecting the basic rights and safety of patients.

[0053] Furthermore, the cross-section of the outer diaphragm 4 is bubble-shaped.

[0054] Furthermore, the threaded rib 2 is spirally wound around the outside of the inner main tube 1.

[0055] Furthermore, the threaded rib 2 is located between the outer diaphragm 4 and the inner main tube 1.

[0056] Furthermore, the outer diaphragm 4 and the threaded rib 2 are at different heights relative to the outer surface of the inner main tube 1.

[0057] Furthermore, the outer diaphragm 4 and the threaded rib 2 are at the same height relative to the outer surface of the inner main tube 1.

[0058] Furthermore, the spacing between the outer diaphragm 4 and the inner main tube 1 is configured such that when the heating wire 3 of the threaded rib 2 is heated, an air layer is formed between the outer diaphragm 4 and the inner main tube 1.

[0059] Furthermore, the spacing between the threaded ribs 2 is equal.

[0060] Furthermore, the spacing between the outer diaphragm 4 and the inner pipeline 1 is equal.

[0061] Based on the surface-coated heat-insulating tube provided in this application embodiment, since heat transfer in air is less effective than in solids, it can effectively solve the problem of heat transfer and diffusion of the gas flowing through the heat-insulating breathing tube during operation, which leads to excessively high temperature of the breathing tube and thus burns the patient's skin, or the problem of water molecules in the air-oxygen mixture condensing and accumulating on the inner wall of the tube due to indirect contact between the heated and humidified air-oxygen mixture inside the tube and the outside cold air after prolonged use.

[0062] It should be noted that the technical solutions of the embodiments of this application also have the following technical details:

[0063] The thermal conductivity of the outer diaphragm 4 is different from that of the inner main tube 1, and the thermal conductivity of the outer diaphragm 4 is lower than that of the inner main tube 1.

[0064] The outer membrane 4 has a bubble-shaped cross-section, which is similar to an ellipse or a circle.

[0065] The outer diaphragm 4 covers the outside of the inner main tube 1;

[0066] The height of the outer diaphragm 4 is higher or lower than the height of the threaded rib 3.
