Abstract
The utility model is related to attract under a kind of glottis and rinse tracheal catheter device; it can effectively ensure that air flue is closed, positive airway pressure, fixed catheter, and can be effectively protected airway mucus; prevent upper respiratory tract secretion and enter lower respiratory tract and lung, to prevent the generation of secondary pulmonary infection.The device is made of main pipe, connector, air bag, foam or sponge dressing, gas tube, pilot balloon, charge valve, several attraction flushing holes, several attraction flush pipes, end cap, catheter port, conduit graduated scale.It is equipped with several attraction flush pipes and gas tube on conduit, wherein flush pipe is attracted to be connected with several attraction flushing holes on conduit, attracts and surrounds foam or sponge dressing in flushing hole;Gas tube is connected with the air bag being arranged on conduit, and graduated scale is arranged on catheter wall, it is reasonable for structure, safe and reliable, using effect is good.
Description
Technical field:
The utility model belongs to medical apparatus technical field, and in particular to attracts under a kind of glottis and rinses tracheal catheter dress
It sets.
Background technology:
Artificial airway is the effective means for ensureing airway patency, particularly important during patient with severe symptoms rescues.However, people
The foundation of work air flue destroys the normal anatomical structure of respiratory tract and physiological function, and air flue protective capability is caused to be destroyed, point
Secretion increases, and epithelium healing secretion is gathered in above tracheal catheter air bag, causes local bacterial to breed, secretion can be through airbag wall
Gauffer, gap leakage between tracheal wall enter downtake, cause Ventilator Acquired tracheobronchitis (VAT) and lung ventilator
Pneumonia (VAP) occurs, and prolonged mechanical duration of ventilation and hospital stays, increases considerably payment for medical care, seriously affects severe
The prognosis of patient.
It is well known that the most basic effect of air bag is to maintain glottis air flue closing below, fixed catheter, to ensure just
Pressure ventilation efficiently accomplishes.The closure of air bag can also prevent pars oralis pharyngis and gastric content accidentally sucking lung, reduce pulmonary infection.
The improve and perfect of air bag never stops.From the 1970s widely applied 1st generation it is low hold high pressure rubber sacculus, to 70
Later stage in age 2nd generation height holds the silica gel or polyoxyethylene air bag of low pressure, then to the circular cone air bag improved in recent years.All air bags are equal
It has the following problems:1) airbag aeration amount is with lucky closed airway, and air flue is air tight (minimal closure technology) when ensureing ventilation, point
Gap of the secretion between air bag and tracheal wall leaks into lung and increases:2) in order to reduce leakage, usually increase airbag aeration
Amount, then cause gasbag pressure excessively high, compression tracheal mucosa, or even the complication such as tracheostenosis, tracheoesophageal fistula occurs;3)
Since tracheae is not regular circle shapes tube chamber, even if increasing airbag aeration amount Subglottic secretion still can pass through airbag wall and gas
Gauffer, gap between tube wall, it is micro constantly to leak into lower respiratory tract, make into lung, especially restlessness, operation etc.
Conduit drawing, displacement, are intubated for a long time, and Subglottic secretion leakage becomes apparent from.This is the pass for causing VAP incidences high
Key factor.The scholars such as Philippart in 2015 CHEST magazines deliver result of study show the taper air bag improved in recent years compared with
Cylindrical airbag fails to reduce VAP incidences.Having multinomial research at present confirms that tracheae of the application with attraction (SSD) under glottis is led
Pipe carries out secretion under glottis and drains, can effectively reduce VAP incidences.But current existing tracheal catheter is between single hole under glottis
It is disconnected to attract, attraction power often is lost because single hole blocks, can not be carried out effectively and reliable infraglottic cavity drainage, to have
Effect removes secretion under glottis and occurs micro- accidentally suction repeatedly, when causing pulmonary infection repeated, thus considerably increasing in hospital
Between and hospitalization cost and the death rate.Therefore, there are no one kind closing gas just in airbag aeration amount in the prior art
Road ensures positive airway pressure, avoids compression tracheal mucosa, and Subglottic secretion can be effectively prevent to leak into lower respiratory tract
Glottis under attract and rinse tracheal catheter;Simultaneously, moreover it is possible to ensure when attracting under carrying out glottis or rinsing, avoid airway mucus
Damage, bleeding, even acutely the complication such as cough and discomfort occur for necrosis, patient's irritation, fundamentally prevent the upper respiratory tract
Secretion enters lower respiratory tract, effectively prevents to attract and rinse tracheal catheter under the glottis of the disposable antiseep of pulmonary infection.
Invention content:
The purpose of this utility model, and providing one kind according to above-mentioned technical problem can ensure that air flue is closed, admittedly
Determine conduit, ensure efficiently accomplishing for positive airway pressure, avoids compression airway mucus, and Subglottic secretion can be effectively prevent
It leaks under a kind of glottis of the disposable antiseep of lower respiratory tract and attracts and rinse tracheal catheter device.The device is by continuing
Or intermittent infraglottic cavity regionality attracts rather than single hole attracts to ensure to attract effect, fundamentally prevents the upper respiratory tract point
Secretion enters lower respiratory tract and lung, effectively prevents pulmonary infection.The utility model is realized in, which includes leading
Pipe, connector, air bag, foam or sponge dressing, gas tube, pilot balloon, charge valve, several attraction flushing holes, several suctions
Draw flush pipe, end cap, catheter port, conduit graduated scale, (as shown in the figure) is provided with several attraction punchings in leading pipe outer wall
Wash pipe and gas tube.Several attract one end of flush pipe to be provided with end cap, and the other end is connected with several attraction flushing holes,
One end of gas tube is connected with pilot balloon and charge valve, and the other end is connected with the air bag of front end on conduit, leading
The rear end of pipe is equipped with connector, separately surrounds foam in several attraction flushing holes of front end on main pipe or sponge is applied
Material, several attract flushing hole and foam or the sponge dressing closely company of folding, so that negative pressure is passed to entire foam or sponge dressing
It passs.Digital calibration ruler is provided on conduit outer wall, the front end of conduit is set as ellipticity, and offers nose circle in side
Mouthful.
