Abstract
The utility model discloses a heating wire for heating gas in a long pipe of a noninvasive ventilator. The heating wire is characterized by comprising a pipe body, wherein the pipe body is made of flexible materials, the diameter of the pipe body is smaller than the inside diameter of the long pipe, and the pipe wall of the pipe body is internally provided with filaments. When the heating wire is in use, one end of the heating wire is connected with a pressure sensor of the noninvasive ventilator, and the other end of the heating wire is inserted into the long pipe, connected with a face mask, of the noninvasive ventilator and extends to the face mask. Since the heating wire is tubular, and the pipe wall is provided with the filaments, when the noninvasive ventilator works, gas flow in the long pipe can be heated, and the pressure at the face mask can be detected while the long pipe coveys the gas flow. The heating wire has the advantages of compact and reasonable structure, high heating efficiency and good use effect.
Description
Technical field
This utility model belongs to the breathing apparatus accessory, is specifically related to a kind of heater wire of heating for gas in the noninvasive ventilator long tube.
Background technology
The noninvasive ventilator main frame is sent into the face shield patients with gas through long tube and is breathed, when cold to winter, it is cold that patient can feel, breath also can be met cold junction and be revealed, cause in patient's face and the long tube liquid is arranged, therefore need the gas temperature in the heating long tube face shield, generally adopt the heating long tube at present or heater wire is placed on mode heated air in the long tube.The heating long tube is compared with heater wire, and the efficiency of heating surface is lower.Heater wire is placed in the long tube, and heater wire at first heats gas in the long tube, and the air that reheat long tube and long tube are outer compare heating long tube outer air still less with the heating long tube, so the efficiency of heating surface is higher.In addition, many noninvasive ventilators need detect the pressure at face shield place, generally adopt the plastic tube of hollow or silica gel tube to be connected with pressure transducer on the main frame, the other end of plastic tube or silica gel tube is placed near in face shield or the face shield, thereby the pressure in the detection face shield is placed heater wire and pressure detecting pipe simultaneously in long tube, has reduced space in the long tube, improved the resistance of long tube, it is inconvenient again outward that the pressure detecting pipe is placed long tube.
The utility model content
The purpose of this utility model provide a kind of result of use good be used for the heater wire that gas is heated in the noninvasive ventilator long tube.
The technical scheme that realizes the employing of this utility model purpose is as follows:
This utility model provides is used for the heater wire that gas is heated in the noninvasive ventilator long tube, comprises that diameter that flexible material makes less than the body of long tube internal diameter, is provided with electrical heating wire in the tube wall of described body.
Further technical scheme is:
The front end of described heater wire is provided with temperature or Temperature Humidity Sensor.
When heater wire of the present utility model uses, an end of heater wire is connected with the pressure transducer of noninvasive ventilator, the other end of heater wire inserts noninvasive ventilator, and to connect the long tube of face shield interior and stretch to the face shield place.Because heater wire is tubulose, tube wall is provided with electrical heating wire, when noninvasive ventilator is worked, when guaranteeing the long tube delivery air, both can heat the air-flow in the long tube, can detect the pressure at face shield place again.It is reasonable to the utlity model has compact conformation, efficiency of heating surface height, the advantage that result of use is good.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

The specific embodiment
Embodiment 1
See Fig. 1, be used for the heater wire that gas is heated in the noninvasive ventilator long tube, comprise that diameter that flexible material makes is less than the body 2 of long tube internal diameter, body 2 can adopt silica gel or other insulating polymeric material, be provided with electrical heating wire 3 along body 2 in the tube wall of described body 2, electrical heating wire 3 is at the external connection lead 1 of an end of body 2.
The operating position of this utility model heater wire, as shown in Figure 2, the rear end of heater wire A is connected with pressure transducer 6 in the noninvasive ventilator 5, the front end of heater wire A inserts in the long tube 7 that noninvasive ventilator 5 connects face shields 8 and stretches to face shield 8 places, in electrical heating wire 3 and the respirator main frame 5 or independent heating control apparatus (not shown) be connected, because heater wire is tubulose, tube wall is provided with electrical heating wire 3, when noninvasive ventilator 5 work, when guaranteeing the long tube delivery air, both can heat the air-flow in the long tube, can detect the pressure at face shield place again.Also can by heating control apparatus and be located at temperature in the face shield 8 or the temperature of Temperature Humidity Sensor 9 control heated air or humiture to meet necessary requirement.
Embodiment 2
Seeing Fig. 2, is that the front end of described heater wire body 2 is provided with temperature or Temperature Humidity Sensor 9 with embodiment 1 difference.Can not establish temperature or Temperature Humidity Sensor in the face shield like this.
Claims (2)
1. one kind is used for the heater wire that gas is heated in the noninvasive ventilator long tube, it is characterized in that comprising that diameter that flexible material makes less than the body of long tube internal diameter, is provided with electrical heating wire in the tube wall of described body.
2. heater wire of heating for gas in the noninvasive ventilator long tube according to claim 1 is characterized in that the front end of described heater wire is provided with temperature or Temperature Humidity Sensor.
