Description

The preheating device of the interval pipeline of pneumatic supply and damper

Technical field

This utility model system is relevant for respiratory organ, particularly a kind ofly at the pneumatic supply of respiratory organ and the pipeline between the damper heating member is set, to reduce the condensation hydrops that damper is excessively exported humidity and caused.

Background technology

Respiratory organ (humidification apparatus or respiratory humidification system) is hospital emergency rooms and the common Medical Instruments of intensive care unit, when sufferer itself can't be breathed voluntarily, or can breathe voluntarily but can't reach the oxygen concentration of needed by human body the time, namely need install respiratory organ additional to earn a bare living, for example the sufferer of pulmonary lesion such as SARS, H1N1 or the person of being wound of pulmonary.

The respiratory organ start principle that Fig. 1 discloses, gas supply device (gases supply means) the built-in fan of pneumatic supply 1 or air that the compressor (not shown) produces will be generally called as shown by arrows in system, deliver to damper (humidifier) 3 through interval pipeline (conduit) 2; This damper comprises water container (humidification chamber) 31 and electric hot plate (heater plate) 32; With the heating of the moisture carrier in 22 pairs of water containers of electric hot plate 21, the gas that pneumatic supply is provided is taken away moisture carrier endogenous cause of ill and is heated and the steam of evaporation, is flowed to sufferer 5 optimal breathing temperature and is breathed humidity by suction line (inspiratory conduit) 4 again.

The steam that produces of device heating moisture content carrier is usually before no show sufferer end through moisture, steam is easily because of ambient temperature, air-flow size and gas flow temperature influence, make transmission temperature and steam at the suction line internal loss, and then produce the condensate water of common name condensation (condensation).

In order to reduce the hydrops that condenses, the general practice is heating member (heating wire means) 41 to be set with holding temperature in suction line.

The other practice is the loss that the heating power of raising damper remedies temperature and steam.But heating power is more big, and the temperature that damper produces and steam consume also can increase synchronously, and the hydrops speed in the suction line is speeded on the contrary, and severe patient will cause the obstruction of suction line.

In addition, the gas temperature that gas supply device produces is far below the heating-up temperature of damper, and gas is too short by the time of moisture carrier, not only can't mix with steam fully, there is not time enough that cold air is heated, to such an extent as to just condense in the suction line before the steam no show sufferer still end yet.

In order to improve the condensation problem of above-mentioned suction line, the Fisher ﹠amp of New Zealand manufacturer of operation circle the ears of an ox or cow; Paykels Healthcare Limited proposes following multinomial United States Patent (USP): 8,206,337,8,037,882,7,958,891,7,559,324,7,263,994,7,146,979,7,043,979,6,918,389,6,662,802, RE40,806, RE39,724.Only, the settling mode that above-mentioned patent proposes or because pipeline adopts the high-tech material, or too complicated because of pipeline structure makes implementation cost too high, and is unpopular and can't widespread.

Because suction line condensation hydrops is to the influence property of respiratory organ allomeric function running, and the sense of discomfort that sufferer is caused, as how simplifying most but the mode of full blast is improved, believe the problem that has very much researching value.

Summary of the invention

The purpose of this utility model is a kind of novel respiratory organ of invention, can reduce in the respiratory organ damper and excessively export the condensation hydrops that humidity causes.

The purpose of this utility model is realized by following technical scheme:

The preheating device of the interval pipeline of a kind of pneumatic supply and damper comprises:
