Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a double-layer high-flow oxygen therapy tube for heating and humidifying pipelines. Background Art

[0002] The ventilator is a crucial medical device in the ICU, preventing and treating respiratory failure, reducing complications, and saving and prolonging patients' vital signs. A humidifier is a crucial component of the ventilator, warming and humidifying the inhaled gas, effectively reducing secondary respiratory infections and cardiopulmonary stimulation in mechanically ventilated patients, and maintaining alveolar moistness. Each humidifier is equipped with an oxygen therapy tube. Currently, the active heated humidifiers used with ventilators on the market warm and humidify the airway during intubation or tracheotomy, but this can lead to over-humidification and the accumulation of condensed water. While this can be addressed by adding a water collection cup to the heated breathing circuit, the water in the cup must be regularly cleaned by the nurse. High-flow oxygen therapy catheters use the same tube for both exhalation and inspiration, making the use of a water collection cup impossible. Therefore, addressing the condensed water issue has become a pressing clinical issue. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a double-layer high-flow oxygen therapy tube which can increase the heat preservation effect and prevent the generation of condensed water.

[0004] In order to solve the above-mentioned existing technical problems, the present invention adopts the following solution: a double-layer high-flow oxygen therapy tube, including an outer tube, an inner tube and a heating wire, the end of the heating wire is connected to the power connector, and the power connector is connected to the hook on the connector second after passing through the heating wire through the connector one. An inner tube is installed between the connector one and the connector two, the inner tube is placed on the outer layer of the heating wire, the inner tube is covered with the outer tube and a gap is provided between the inner tube and the outer tube, and the outer tube is installed between the connector one and the connector two.

[0005] Preferably, the connector 1 is provided with an annular groove 1 and a step 1, wherein the annular groove 1 is clamped and connected to the inner tube, and the step groove 1 abuts against the end of the outer tube.

[0006] Preferably, the second connector is provided with an annular groove 2 and a step 2, wherein the annular groove 2 is clamped and connected to the inner tube, and the step groove 2 abuts against the end of the outer tube.

[0007] Preferably, the heating wire is provided with a buckle ring, which is connected to the hook buckle.

[0008] Preferably, the end of the heating wire passes through connector 1 and is connected to the power connector.

[0009] The present invention adopts the above technical solution to provide a double-layer high-flow oxygen therapy tube, which has the following advantages compared with the existing technology:

[0010] 1. The heating wire adopts a double-helix structure. First, the heating wire ensures that the temperature inside the pipe is evenly distributed when it is working; secondly, the heating wire is close to the pipe wall to prevent the temperature from falling below the leak point and forming condensed water; finally, it can also reduce the airflow resistance of the pipeline.

[0011] 2. The double-layer tube structure not only has a certain thermal insulation effect, but also can prevent the generation of condensation water, providing patients with gas of a certain temperature and humidity, and reducing the risk of condensation water entering the patient's lungs and causing infection.

[0018] like Figure 1-5As shown, a double-layer high-flow oxygen therapy tube includes an outer tube 1, an inner tube 2 and a heating wire 3. The end of the heating wire 3 is connected to the power connector 4. The power connector 4 is connected to the hook 7 on the connector 2 6 after passing through the connector 1 5 through the heating wire 3. The inner tube 2 is installed between the connector 1 5 and the connector 2 6. The inner tube 2 is placed on the outer layer of the heating wire 3. The outer tube 2 is covered with the outer tube 1 and a gap is provided between the inner tube and the outer tube 1. The outer tube 1 is installed between the connector 1 5 and the connector 2 6. The connector 1 5 is provided with an annular groove 1. 8 and step 1 9, wherein the annular groove 1 8 is snap-connected with the inner tube 2, the step groove 1 9 is against the end of the outer tube 1, the heating wire 3 is close to the wall of the inner tube 2, and the heating wire 3 is a double helix structure, the connector 2 6 is provided with an annular groove 2 10 and a step 2 11, wherein the annular groove 2 10 is snap-connected with the inner tube 2, the step groove 2 11 is against the end of the outer tube 1, the heating wire 3 is provided with a buckle ring 12, the buckle ring 12 is snap-connected with the hook 7, and the end of the heating wire 3 passes through the connector 1 5 and is connected to the power connector 4.

[0019] During actual work, a heating wire 3 is installed on the power connector 4. The heating wire 3 is passed through the connector 1 5 through the power connector 4 and then embedded in the inner side of the inner tube 2 and connected to the hook 12 on the connector 2 6. The two ends of the inner tube 2 are respectively sleeved on the annular groove 1 7 of the connector 1 5 and the annular groove 2 9 of the connector 2 6. The outer tube 1 is sleeved on the outside of the inner tube 2. The two ends of the outer tube 1 are respectively sleeved on the step 1 8 of the connector 1 5 and the step 2 10 of the connector 2 6.
