Abstract

The invention provides a subglottic sucking device for artificial airway. The subglottic sucking device for artificial airway is a one-use medical consumption material closely related to clinical care and nursing. The device comprises a negative pressure connecting tube, a draining tube and a collecting bottle. The device is characterized in that the collecting bottle is manufactured from transparent plastic and equipped with scales, and the collecting bottle is 500ml in capacity; a plug is arranged an opening of the collecting bottle; the negative pressure connecting tube and the draining tube are inserted through the plug; the other end of the negative pressure connecting tube is connected with a central negative pressure part through a negative pressure draining gauge; the other end of the draining tube is connected to a subglottic sucking end of catheter of artificial airway of a patient; when in operation, subglottic secreta of the patient is drained into the collecting bottle through the draining tube under the negative pressure effect. The device is simple to use, safe, sanitary, difficult to cause cross infection, and convenient to handle.

Description

Suction device under artificial airway's glottis

Technical field:

The expendable consumed product of medical treatment, nursing.

Background technology:

Current research shows, the foundation of artificial airway reduces the ciliary movement of coughre flex and tracheal mucosa, destroy the defense mechanism of normal air flue, the pathogenic bacterium of gastric can be driven in the wrong direction and are colonizated in pars oralis pharyngis, the pathogenic bacterium that the secretions of these pars oralis pharyngises and gastric backflow often are gathered in above the air bag of endotracheal tube, it is the major reason that Ventilator Associated Pneumonia occurs that the mistake of research report tracheal intubation or tracheostomy cannula Subglottic secretion is inhaled, and removes the generation that retentate under glottis significantly can reduce Ventilator Associated Pneumonia.By means of the artificial airway with drainage catheter under glottis in clinical nursing activity, continue to attract under carrying out glottis, the amount of secretions under dynamic evaluation patient glottis, color, character and select suitable flushing liquor, periodic flushing pipeline, the effect attracted under can ensureing glottis reduces complication.At present, the domestic Continuous aspiration of subglottic secretions device that is not equipped with specially carries out continuing to attract, attract with homemade device clinically, can not be qualified in aseptic, a lot of case secretions effectively can not attract secretions on air bag when comparing thickness, also must disconnect when saline injection flushing pipe and air bag, violate aseptic principle, easily cause infection.

Summary of the invention:

In order to overcome when artificial airway, suction device under disposable artificial airway's glottis is not had to bring the deficiency of clinical manipulation I & A aspect, the invention provides suction device under a kind of artificial airway's glottis, this device can not only reach aseptic principle, and I & A can be carried out easily, observe amount, the normal complexion character of drain.

The technical solution adopted for the present invention to solve the technical problems is: under artificial airway's glottis, suction device is a kind of airtight disposable sterilized use consumptive material, forms primarily of a negative pressure connection tube, a drainage tube and receiving flask three part.Receiving flask selects transparent plastic and with scale, convenient color and amount, character of observing secretions, to understand the change of the state of an illness, be not easy fragmentation, calibration capacity line is clear, capacity 500ml, and being applicable to Continuous aspiration of subglottic secretions and collecting secretions, is disposable product.Receiving flask bottleneck has bottle stopper, inserts negative pressure connection tube and drainage tube by bottle stopper.Negative pressure connection tube can directly regulate negative pressure drainage pressure by negative pressure drainage table, and its other end is connected to central negative pressure place.The other end of drainage tube is connected on suction side under the glottis of artificial airway for patients conduit.During operation, by negative pressure, infraglottic for patient secretions is drained in receiving flask.There is drainage tube side pipe at the 5CM place that drainage tube is connecting suction side conduit under artificial airway's glottis, and this place can connect syringe or infusion strap carries out pipeline and infraglottic I & A, prevents inadequate drainage and results in blockage.Bottleneck, with lanyard, by the method for Portuguese bowline, hangs over rope on bottleneck, the not easily slippage of such rope, can directly hang in bed.

This product is the conventional consumable goods of medical treatment, nursing, when Continuous aspiration of subglottic secretions, attract on pipe end and vacuum table under directly this device being connected on patient's glottis respectively, adjustment pressure, use fairly simple, safety and sanitation, not easily cause cross infection, be finished and directly throw away in yellow refuse bag, deal with more convenient.

Accompanying drawing illustrates:

Below in conjunction with accompanying drawing, the present invention is further described.

Detailed description of the invention:

Under setting forth this practical artificial airway's glottis further below by using method, suction device arranges structure.During use, negative pressure connection tube (1) directly connects negative pressure drainage table (6) and central negative pressure junction (7), drainage tube under glottis (2) is directly connect suction side under the glottis of patient, receiving flask (5) is fixed on patient bed by lanyard, regulate vacuum table, open negative pressure, secretions can drain in receiving flask (5) along drainage tube under glottis (2), when secretions compare thickness need to rinse time, directly can carry out I & A by drainage tube side pipe (3).

Claims

1. suction device under artificial airway's glottis, is made up of a negative pressure connection tube, a drainage tube and receiving flask three part, it is characterized in that: receiving flask bottleneck has bottle stopper, inserts negative pressure connection tube and drainage tube by bottle stopper.The negative pressure connection tube other end passes through negative pressure drainage list catenation in central negative pressure place.The other end of drainage tube is connected on suction side under the glottis of artificial airway for patients conduit.

2. suction device under the artificial airway's glottis according to claims 1, it is characterized in that there is drainage tube side pipe at the 5CM place that drainage tube is connecting suction side conduit under artificial airway's glottis, this place can connect syringe or infusion strap carries out pipeline and infraglottic I & A.
