Benefits of technology
"The present invention provides an air delivery pipe with a heating device for maintaining the temperature of warm and humid air delivered to patients. The heating device is detachable and can be directly replaced if damaged, reducing costs. The heating device is disposed with a transparent cover for checking the status of the warm and humid air delivered in the tube. The technical effects of the invention include improved temperature control, reduced costs, and improved monitoring of air quality."
Problems solved by technology
However, by increasing the temperature of warm and humid air in the container, the problem of water by the vapor condensation still exists.
Besides, when the temperature of warm and humid air is increased, the amount of sterile water and the cost are also elevated correspondingly.
However, this structure will render the warm and humid air swirling and will fail to fluidly delivering the warm and humid air to patients.
However, exposing the heating wires to the warm and humid air is also a dangerous potential.
However, the cost will be elevated as a result of integrating the heating wires and the air delivery pipe.
When the air delivery pipe is damaged to cause air leakage, it is not economic to replace the whole pipe together with the heating wires in order to meet the requirement of medical quality.

Embodiment Construction
[0020]FIG. 1 is a using-state diagram showing an air delivery pipe 1 of the present invention used in a humidifying apparatus 9. A humidifying apparatus 9 comprises a container 91 and a heater 92. An air inlet hole 911, an air outlet hole 912, and a water inlet hole 913 are provided on the container 91. When dry air is delivered from a main station 93 to the container 91 via an air inputting pipe 94 and the air inlet hole 911 while sterile water is delivered from a supply bag 95 to the container 91 via the water inlet hole 913, the container 91 is heated by the heater 92. The vapor generated from the sterile water is mixed with the dry air to form warm and humid air, which is delivered to patients via the air outlet hole 912 and an air delivery pipe 1 of the present invention.
[0021]The tube is made by plastics, preferably EVA or Hytrel, and is a flexible and hollow tube used for delivering warm and humid air. Besides, the tube also can be made by silicone.

An air delivery pipe of a humidifying apparatus comprises a hollow tube used for delivering warm and humid air and is wrapped by a heating device on its outer peripheries. The heating device includes a first connecting member and a second connecting member, where the first connecting member is disposed at one lateral side of the heating device while the second connecting member is disposed at another lateral side of the heating device for attaching the heating device to the outer peripheries of the tube. Air in the tube is heated by means of a heating element within the heating device.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a humidifying apparatus and, more particularly, to an air delivery pipe used in a medical humidifying apparatus having a tube wrapped by a detachable heating device on the peripheries of the tube.[0003]2. Description of the Prior Art[0004]Humidifying apparatus is used widely in an intensive care unit or a respiratory intensive care unit of a hospital for supplying air to patients of acute surgical operation or of chronic respiratory diseases.[0005]Generally, a humidifying apparatus comprises a chamber, on which are disposed with an air inlet hole, an air outlet hole, and a water inlet hole. After air and sterile water are delivered respectively via the air and the water inlet holes, warm and humid air is generated by a heating device. Then the warm and humid air is delivered from the air outlet hole via an air delivery pipe to patients.[0006]The preferable temperature range of the warm a...
