Description

Novel outer wall heating breathing pipeline

Technical Field

The invention relates to the technical field of humidifying and heating respirators, in particular to a novel outer wall heating breathing pipeline.

Background

Most of the heating breathing pipelines in the existing breathing machine heating breathing pipeline product can not well solve the problem of condensed water in the pipelines: for example, in the traditional bellows heating, a heating wire is arranged in a bellows, and the heating wire provides energy loss when gas is transmitted in a breathing pipeline, but due to the rugged corrugated structure on the wall of the bellows, the heat provided by the heating wire cannot be well diffused to the corrugated structure on the wall of the bellows, and in addition, the heat loss in the pipeline is serious because the heat dissipation area of the bellows is too large, so that a large amount of condensed water is generated at the corrugated part; still a neotype smooth type heating line of inner wall, constitute by rib structure and piece membrane structure, the heating wire is directly moulded plastics in the rib, the heating line of this kind of structure has not had the fold on the pipe wall, but because the rib is thicker partially, the heat that the heating wire generates heat in the rib can not be fine conveys in the piece membrane, the piece membrane between the rib is thinner in addition, calorific loss is great, heat in the pipeline distributes from this place easily, lead to the interval of rib and rib promptly the piece membrane district still to have the comdenstion water gathering.

Traditional heating breathing circuit, because the problem of condensate water in the solution pipeline that design defect can not be fine produces the comdenstion water easily at the inner wall of way pipe, and the existence of comdenstion water probably causes great breathing hidden danger, easily breed the bacterial infection patient including the comdenstion water, the comdenstion water easily blocks up the breathing return circuit pipe, leads to carrying the gas of patient end and not reaching relative standard humiture, causes the breathing discomfort of patient easily, probably causes the patient to breathe difficulty even and endanger patient life safety. Therefore, a new heating breathing pipeline which can better solve the problem of condensed water needs to be designed.

Preferably, the pipe body is composed of a sheet film and ribs, the ribs are spirally wound on the outer wall of the sheet film, and the ribs and the sheet film are integrally formed by extrusion molding.

Preferably, the heating wire is formed by embedding two glass fibers wound with heating wires into an insulating sheath, wherein the heating wires are spirally wound on the glass fibers, and the two glass fibers are not in contact with each other in the insulating sheath.

Preferably, the heating wire is wound between two adjacent ribs.

Preferably, the outer side of the pipe body is sleeved with a heat-shrinkable film which can tightly wrap the heating wire.

Preferably, the pipe body can be bent at will, and the inner wall of the pipe body is designed to be a smooth surface.

Preferably, the two ends of the pipe body are sleeved with connectors, the connectors and the pipe body are integrally formed in an injection molding mode, one connector is provided with an electrical interface and a sensor interface, and a terminal in the electrical interface is in butt joint with the heating wire.

The beneficial conditions of the invention are as follows:

1. the heating wire is designed to be wound at the film part of the pipe body instead of the ribs, so that the heat loss at the thinnest part of the pipeline can be compensated to the maximum extent;

2. the heating wire is externally wound on the outer wall of the tube body instead of the tube, so that the airflow resistance of the tube can be effectively reduced, and a patient has good breathing experience;

3. the heating wire is coated with a layer of thermal shrinkage film, so that the heating wire can be prevented from falling off in the moving or bending process of the heating pipeline, and a certain heat preservation effect can be achieved.

Detailed Description

As shown in fig. 1, 2, 3, 4, a novel outer wall heating breathing pipeline, including body 1, heater wire 4, pyrocondensation membrane 8, joint 9, the winding of body 1 outer wall have heater wire 4, heater wire 4 adopts winding heater strip 7 to constitute on glass fiber 6, the parcel has pyrocondensation membrane 8 in the body 1 outside, the joint 9 has been cup jointed at body 1 both ends. The body 1 constitute by piece membrane 2 and rib 3, and the spiral winding of rib 3 is in 2 outer walls of piece membrane, rib 3 and 2 formula extrusion molding as an organic whole of piece membrane. The heating wire 4 is formed by embedding two glass fibers 6 wound with heating wires 7 into an insulating sheath 5, the heating wires 7 are spirally wound on the glass fibers 6, and the two glass fibers 6 are not in contact with each other in the insulating sheath 5.
