Description

Technical Field

[0001] The present invention relates to the field of pipeline production devices and processes, and in particular to a breathing pipeline production device and a breathing pipeline production method. Background Art

[0002] Breathing pipelines are widely used in the field of respiratory therapy. Once respiratory therapy is required, the respiratory support time is relatively long. Especially for newborns and children, their airways are relatively immature and cannot tolerate dry and low-temperature inhaled gases. Therefore, when directly performing intubation ventilation, it is necessary to warm and increase the humidity of the respiratory gases inhaled by the patient; as the air flow transmission carrier from the ventilator to the patient, the purpose of the breathing pipeline is to send the air flow modulated by parameters such as waveform generated by the ventilator to the patient's airway to support the patient's breathing needs; usually, the breathing pipeline adopts the method of externally connecting a heating and humidifying device. The following defects exist in such a heating and humidifying method and gas transmission method: After the gas is heated and humidified, it is easy to cause water vapor to condense and precipitate on the inner wall of the pipeline during the process of being transported to the patient due to the temperature drop in the pipeline. In severe cases, the condensed water will cause the patient to choke on water and even pose a danger; in order to prevent the condensed water from entering the patient's airway, such a pipeline needs to be equipped with a water collection cup, and the water collection cup needs to be kept at a relatively low position in the entire pipeline, and regular drainage or replacement is required; the condensed water will carry out water molecules in the respiratory gas, resulting in insufficient humidity of the respiratory gas; it is necessary to carefully adjust the position of the pipeline and regularly replace the water collection cup, which increases the workload of the user.

[0003] Another method is to use a heating wire built into the pipeline to heat the gas in the pipeline and reduce the generation of condensed water. The following defects exist in this method: 1. When disinfecting this kind of pipeline, it is necessary to carefully take out the heating wire from the pipeline, and then disinfect the pipeline, but the taken-out heating wire cannot be disinfected together with the pipeline; 2. Due to the built-in heating wire, the heating wire will increase the resistance of the air flow; 3. There must be an uneven distribution of the built-in heating wire, and the uneven distribution of the heating wire will cause uneven heating of the gas in the pipeline; 4. Due to the built-in heating wire, the gas will come into contact with the heating wire when transmitting in the pipeline, generating noise, which is not conducive to the patient's recuperation.

[0004] The best way is to use a breathing pipeline with a heating wire fixedly arranged on the pipeline wall, but such a breathing pipeline is not easy to produce, and there are almost no relevant production equipment so far. Summary of the Invention

[0059] S1: Install the heating wire; Install the heating wire spool on the positioning post 35, then wind the heating wire around the first roller 321, the second roller 342 and the fourth roller 13 in sequence and then pass through the heating wire fixing die head 20. The heating wire passes through the first hole 22, the third hole 451 and the fourth hole 461 in sequence. Turn the first adjustment post 33 and the second adjustment post 37 to make the heating wire taut;

[0060] S2: Start the first extruder 10 to preheat the first plastic material, and start the second extruder 50 to preheat the second plastic material. The second plastic material is used to form the inner layer of the breathing tube, and the first plastic material is used to wrap the heating wire and fix the heating wire on the surface of the inner layer of the breathing tube;

[0061] S3: Start the production table 60, the breathing tube die head 61 starts to rotate, control the second extruder 50 to extrude the second plastic material through the second extrusion head 51 onto the breathing tube die head 61, and the second plastic material forms the inner layer of the breathing tube as the breathing tube die head 61 rotates;

The first plastic material flows from the installation hole 41 into the third hole 451, and the first plastic material fills the third hole 451. At this time, the first plastic material wraps the heating wire;

[0063] S5: Pull out the heating wire from the fourth hole 461. At this time, the heating wire is completely wrapped by the first plastic material. Then pull the heating wire completely wrapped by the first plastic material onto the inner layer of the breathing tube.

The inner layer of the breathing tube, the heating wire and the first plastic material form a fixed connection to form the breathing tube;

[0066] Another implementation of the method for producing the breathing pipeline is as follows. After step S4, the heating wire is pulled out from the fourth hole 461. At this time, the heating wire is completely wrapped by the first plastic material, and then the heating wire completely wrapped by the first plastic material is cooled to form a heating wire. The heating wire can be pre-produced. When producing the breathing pipeline, start the production table 60, and the breathing pipe die head 61 starts to rotate. Control the second extruder 50 to extrude the second plastic material through the second extrusion head 51 onto the breathing pipe die head 61. The second plastic material forms the inner layer of the breathing pipeline as the breathing pipe die head 61 rotates. At this time, a heating device is used to heat the heating wire to soften its surface, and then the heating wire is pulled to the surface of the inner layer of the breathing pipeline. As the breathing pipe die head 61 rotates, the heating wire is evenly wound around the surface of the inner layer of the breathing pipeline and fixedly connected to the inner layer of the pipeline to form the breathing pipeline.

[0067] Of course, the present invention can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present invention.
