Description
Technical field
This utility model belongs to medical instruments field, relate to a kind of glottis up and down secretions attract trachea, be specifically related under a kind of conduit intubation glottis, air bag top secretions and pars oralis pharyngis secretions attraction tracheal tube.
Background technology
At present, in the clinical treatment, mechanical ventilationassociatepneumonia pneumonia (ventilator-associated pneumonia, VAP) refer to that tracheal intubation uses Ventilators and pull out 48 hours with the pneumonia of interior acquisition to endotracheal tube after 48 hours, the important form that normally belongs to nosocomial pneumonia (Hospital Acquired Pneumonia, HAP); Have statistics to show, accept that 10-25% can obtain VAP among the respirator treatment patient, VAP 4-16 example occurs in average per thousand respirator days, and (Intensive Care Unit, ICU) patient has 25-28% to obtain VAP in the intensive care unit; The overall mortality rate of described mechanical ventilationassociatepneumonia pneumonia (VAP) is 24-50%, and VAP often causes increasing hospital day, lives ICU day and hospitalization cost, it is reported, need every year hundred million dollars of 50-100 to be used for (the Hospital Acquired Infection of nosocomial infection in the U.S., HAI) control, VAP then is the main composition part of nosocomial infection.
Therefore, prevention VAP then is one of groundwork of nosocomial infection's control.The preventive measure of present described VAP mainly contains: reduce or eliminate field planting tree and the suction of pars oralis pharyngis and gastral cavity pathogen; The drain of secretions under the glottis (Subglottic Secretion Drainage, SSD); The formation of control institute's pipe conduit biofilm (Biofilm, BF); (Selective Digestive Decontamination, SDD) dyed in the decontamination of selectivity digestive tract; Using adapted Antibios; Cut off exogenous route of transmission; Wash one's hands; Share the sterilization of apparatus; Increase patient's immunocompetence etc.
Practice shows, in the clinical treatment, under the glottis of intubation and the gap between the endotracheal tube air bag often has the hydrops of severe contamination to exist, bibliographical information is arranged, check under the glottis of about 56% intubation through x-ray and the gap between the air bag has obvious hydrops to exist, mostly about 3 ~ 15ml.But use attraction tracheal tube timing or lasting this secretions that attracts under the glottis, can reduce the VAP incidence rate, the trachea of secretions is led for clinical practice between relevant attract under the glottis-air bag, yet, the oral secretion that the as easy as rolling off a log generation of intubation is a large amount of, above-mentioned secretions can constantly be displaced downwardly under the glottis, even lower respiratory tract, until cause the generation of VAP.
Up to now, there is not yet relevant report for secretions and pars oralis pharyngis secretions attraction tracheal tube under the conduit intubation glottis, above the air bag.
Summary of the invention
The purpose of this utility model is for overcoming the defective of prior art, provide a kind of glottis up and down secretions attract trachea, relate in particular under a kind of conduit intubation glottis, air bag top secretions and pars oralis pharyngis secretions attraction tracheal tube; This attraction trachea can attract under the intubation glottis, air bag top secretions and pars oralis pharyngis secretions, can obviously reduce and use the Ventilator Associated Pneumonia Probability.
This utility model improves on the basis of existing technology, adopts conventional endotracheal tube and dorsal segment to have the secretions suction catheter of side opening to make.
Particularly, glottis of the present utility model up and down secretions attracts trachea, it is characterized in that, connects negative pressure joint 4, air bag qi of chong channel ascending adversely pipe 5, endotracheal tube connection breathing machine connector 6 and endotracheal tube 7 by endotracheal tube air bag 1, suction catheter 2, suction catheter and forms; Described endotracheal tube 7 one ends are established endotracheal tube air bag 1, the other end is established endotracheal tube and connected breathing machine connector 6, one end of described suction catheter 2 is connected with endotracheal tube 7, its another termination suction catheter connects negative pressure joint 4, establish suction catheter side opening 3 on this suction catheter 2, the end that described suction catheter connects negative pressure joint 4 connects endotracheal tube 7, another termination air bag qi of chong channel ascending adversely pipe 5.
Glottis of the present utility model up and down secretions attracts trachea, is comprised of conventional endotracheal tube 7 and the dorsal segment secretions suction catheter 2 by side opening;
In this utility model, described suction catheter 2 is located at endotracheal tube 7 back sides, is one and half to be incorporated into the thin suction catheter on the endotracheal tube 7, its length is 30cm, after connecting vacuum suction, sustainable or interruption attracts under pars oralis pharyngis and the glottis, the secretions of air bag top, reduces the generation of VAP; Among the embodiment of the present utility model, described suction catheter 2 is positioned at endotracheal tube air bag 1 top with integration place of endotracheal tube 7;
In this utility model, described suction catheter side opening 3 is located on the suction catheter 2, and among the embodiment of the present utility model, suction catheter side opening 3 is provided with 10, suction catheter side opening interval 1cm.
During use, program attracts trachea to insert the reservation position secretions about this glottis routinely, then connect negative pressure joint 4 with suction catheter 2 and lower negative pressure equipment connection by suction catheter, implement to continue to attract or implement to be interrupted to attract, under the sucking-off intubation glottis, air bag top can accumulate secretions, and the secretions of pars oralis pharyngis.
Use is the result show, glottis of the present utility model up and down secretions attracts trachea, can in time attract under the intubation glottis, air bag top secretions and pars oralis pharyngis secretions, can obviously reduce the Ventilator Associated Pneumonia Probability.Nosocomial infection has more important more practical value to control.
