In view of this, the present invention is directed to the absence of the prior art, and its main object is to provide a threaded heating tube that is convenient to use, has a long life, and can ensure that the gas in the tube is kept at a constant temperature, and a preparation method thereof.

In order to achieve the above object, the present invention adopts the following technical solution: a threaded heating pipe comprising a threaded pipe and a heating member, the threaded pipe comprising a pipe body and a threaded portion surrounding the pipe body, the threaded portion is covered with The heating member surrounds the tubular body along the threaded portion, and the threaded portion is integrally formed with the tubular body.

As a preferred solution, the heating member includes a heating wire and an insulator coated on the outer surface of the heating wire.

As a preferred solution, the heating wires are two, and the two heating wires are disposed in parallel with each other and separated by an insulator.

As a preferred solution, the insulator is welded to the threaded tube.

As a preferred solution, one end of the two heating wires is connected to the power source, and the other end is connected to each other to form a heating wire loop.

As a preferred embodiment, the heating temperature of the heating member is maintained between 30 ° C and 37 ° C.

As a preferred solution, the threaded tube is in communication with a gas supply.

A method for preparing a threaded heating tube, wherein two heating wires are respectively placed in an insulator to form a heating member, and then the threaded tube and the heating member are overmolded, that is, the heating member is welded while the threaded tube is extruded. A threaded heating tube is formed in the threaded portion of the threaded tube.

The heating wire and the insulator in the heating member are overmolded, that is, the two heating wires are respectively covered by an insulator and parallel to each other and separated by an insulator.

Compared with the prior art, the invention has obvious advantages and beneficial effects. On the one hand, by using a heating component on the threaded portion of the threaded pipe as an oxygen gas delivery pipe, under the action of the heating component, the inside of the pipe can be effectively ensured. The gas maintains a temperature suitable for the patient's breathing. The use of the threaded heating tube is convenient and quick, and provides a suitable temperature of oxygen to a plurality of patients in the same air supply device. It is not necessary to equip each patient with a heated humidifying bottle to achieve systematization. Oxygen supply; on the other hand, the two heating wires in the heating member are separately wrapped in the insulator and then integrally extruded by the threaded tube, so that the two heating wires of the heating member can be effectively ensured during the processing. Wound together to avoid the phenomenon of short-circuit of the heating wire, improve the life of the product, and have great market value.

detailed description

Referring to Figures 1 through 3, there is shown a specific construction of a preferred embodiment of the present invention, a threaded heating tube comprising a threaded tube 10 and a heating member 20.

The threaded tube 10 includes a tubular body 11 and a threaded portion 12 surrounding the tubular body 11. The threaded portion 12 is covered with the heating member. The heating member 20 surrounds the tubular body 11 along the threaded portion 12, and the threaded portion 12 is integrally formed with the tube body 11. The threaded tube 10 is in communication with a gas supply device through which the gas supply device supplies air to the patient.

The heating member 20 includes a heating wire 21 and an insulator 22 coated on the outer surface of the heating wire 21. The heating wires 21 are two, and the two heating wires 21 are disposed in parallel with each other and separated by an insulator 22, and each of the heating wires 21 is placed in the insulator 22 independently of each other, so that the short-circuiting of the heating wire 21 is not caused. The insulator 22 is welded to the threaded tube 10 by overmolding.
