Description

Air flue humidification device in Critical Care

Technical field

The utility model relates to the breathing assistance apparatus in the work of intensive care unit, specifically design a kind of air flue humidification Device.

Background technique

Air flue humidification is the important link of Airway Care after artificial airway establishes.Air flue humidification can not cause air flue mucous membrane completely The destruction and flattening of pseudostratified columnar epithe lium and cuboiodal epithelium, trachea-bronchial epithelial cell mucosa cells are denaturalized, fall off, mucosa ulcer. It is impaired to eventually lead to Mucociliary clearance function, small airway collapses, atelectasis etc..Research shows that the degree of Airway damage with without wet It is directly proportional to change the gas ventilation time.

If in nursing process, gas is directly entered lower respiratory tract without humidifying and filtering after tracheotomy, cause to breathe Mucous membrane is dry, sputum is sticky, and airway obstruction easily causes pulmonary infection.And experiments have shown that: pulmonary infection is with gas humidification journey The reduction of degree and increase.In addition, there is also non-visible dehydration situations for normal condition lower respiratory tract.Therefore good after tracheotomy Air flue warm and humidization is significant to maintenance respiratory tract mucus-cilium system normal physiological function and defense function.

Wetting approach at this stage essentially consists in:

Traditional wetting approach mainly have in air flue interruption instilled humidification, micro pump per hour nominal speed be pumped into, Atomizer intermittently or continually humidifying etc..These methods itself do not provide temperature, are a kind of cold humidifyings, humidifying is ineffective, simultaneously Also respiratory tract microorganism can be caused to move down the generation so as to cause pulmonary infection.

Or use autogenous cutting type artificial nose, autogenous cutting type artificial nose can effective filter bacteria, guarantee certain humidifying effect, It is current clinical a kind of more common method.But artificial nose, which uses, certain contraindication, sticky for abundant expectoration, hypothermic Patient is not applicable.Artificial nose use has some cycles, generally uses (≤96 hours) in a short time, and channel replaces artificial nose Not only increase the increase that nursing work load also results in department's economic cost and patient's hospitalization cost.

There are also one is the high flow capacity breathing humidification instrument of striking snow parker production can be for 21-100% oxygen Concentration is accurately adjustable, flow velocity up to 60L/min high flow capacity gas, while can for 37 DEG C, relative humidity 100%, The saturated gas of 44 mg/L of absolute water content can provide good humidifying by dedicated autogenous cutting face mask for patient.But it should Equipment is expensive, and it is non-in tracheotomy to limit it as a kind of disposable high-value consumables to a certain extent for the autogenous cutting face mask specially matched Clinical application in patients with mechanical ventilation air flue humidification.

In conclusion related technical personnel have found in long-term working practice, at this stage in technology or price it is high Expensive or humidifying effect is poor, influences the therapeutic effect of patient, or even is easy to happen infection.
