Description

Heating breathing machine pipeline

Technical Field

The utility model relates to a disposable heating breathing machine pipeline.

Background

The humidifier or the breathing machine is an important component of the breathing machine, a physical heating method is used for providing proper temperature and humidity for dry air-oxygen mixed gas, the heating and humidification of patient gas treated by the breathing machine by using the breathing humidifier are important measures in the treatment process, for example, the breathing humidifier fails and directly affects the treatment effect of the patient, the patient is injured by serious failure, and the humidifier and the breathing machine are required to be matched with a plurality of matched parts for use in the working state, for example, in order to ensure the temperature during air outlet, a merchant often installs a breathing machine pipeline on the humidifier, so as to control the temperature during air outlet.

For this reason, the patent with the publication number CN214860315U also discloses a disposable heating ventilator circuit, which directly exposes the heating wire to the outside, so that potential safety hazards are easily generated.

Disclosure of Invention

The utility model aims to solve the technical problems: how to design a safer disposable heating breathing machine pipeline.

The technical scheme of the utility model is as follows:

the utility model provides a disposable heating breathing machine pipeline, includes the heating pipeline, and the tip of heating pipeline is the joint, and the joint is used for being connected with normal breathing machine pipeline, and the surface of heating pipeline is equipped with heliciform heater strip, and the outer parcel insulating layer of heater strip, the insulating layer is fixed at the surface of heating pipeline.

Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-2, a disposable heating ventilator circuit comprises a heating circuit 10, wherein a connector 20 is arranged at the end of the heating circuit 10, the connector 20 is used for being connected with a normal ventilator circuit (non-heating ventilator circuit) as much as possible, a spiral heating wire 11 is arranged on the outer surface of the heating circuit 10, an insulating layer 12 is wrapped outside the heating wire 11, and the insulating layer 12 is fixed on the outer surface of the heating circuit 10.

The insulating layer 12 is plastic and is fixed with the heating pipe by hot press molding.

In order to keep the connection between the disposable heating ventilator circuit and the non-heating ventilator circuit stable, the disposable heating ventilator circuit and the non-heating ventilator circuit bear the pulling force of 45 newtons and are not separated, so the connection part of the disposable heating ventilator circuit and the non-heating ventilator circuit is complex, such as threaded connection, telescopic sleeve connection and the like.

When using a threaded connection, one of the pipes needs to be rotated, which is time consuming and not easy to operate (since the other end of the rotated pipe may also be connected to other equipment).

When the telescopic sleeve is used, two pipelines are required to be sleeved together, and the telescopic sleeve is sleeved at the joint of the two pipelines, so that the telescopic sleeve is complicated.

To this end, as shown in fig. 3 to 4, the joint 20 is made of an elastic material (such as plastic or rubber) and includes an annular inner joint layer 22 and an annular outer joint layer 21, and an annular space between the inner joint layer 22 and the outer joint layer 21 is a joint chamber 23.

The working principle is as follows:

when the utility model is manufactured, the heating wire 11 is coiled on the outer surface of the heating pipeline 10, and then the insulating layer 12 (namely plastic) and the heating wire 11 are fixed on the outer surface of the heating pipeline 10 by using a hot press molding technology.

As shown in fig. 5, when the disposable heating ventilator circuit is connected with the non-heating ventilator circuit, the connector of the non-heating ventilator circuit (see reference numeral 90) is inserted into the connector chamber 23, so that the connector inner layer 22 and the connector outer layer 21 are extruded to deform, the reaction force F generated by the deformation presses the connector of the non-heating ventilator circuit (see reference numeral 90), and the connector of the non-heating ventilator circuit (see reference numeral 90) receives the reaction force F on two sides, because the maximum static friction force between the disposable heating ventilator circuit and the non-heating ventilator circuit is proportional to the pressure, the maximum static friction force is larger, and can reach 75 newtons, so that the connection stability of the disposable heating ventilator circuit and the non-heating ventilator circuit is enough to be kept.

How to heat the disposable heating ventilator circuit is the prior art is not described in detail.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
