Abstract
The invention relates to a device capable of guaranteeing airtightness of an airway when a suction catheter or a fiberobronchoscopy is utilized to remove airway secretions under mechanical ventilation. The smooth implementation of the mechanical ventilation requires for effective removal of the airway secretions and airtightness of the airway, and existing methods for removing the airway secretions cannot meet the two requirements simultaneously. The device can guarantee airtightness of the wounded mechanical ventilation airway when the suction catheter or the fiberobronchoscopy is utilized to remove the secretions. The device is characterized in that a round hole is arranged on a connecting piece positioned between a tracheal cannula and a ventilation loop, at least three layers of tightly attached elastic films are attached to the round hole, each layer of film is provided with a small hole which has a smaller diameter than the external diameter of the suction catheter and the external diameter of fiberobronchoscopy, small holes of the adjacent films are crossed, and the small film hole of the uppermost layer and the small film hole of the lowermost layer are not crossed. Accordingly, the suction catheter can remove the airway secretions through the small film holes, and airtightness of the airway is guaranteed.
Description
Technical field:
This patent relate to a kind of can continue to have utilize sputum aspirator tube or branchofiberoscope to remove airway secretions under the wound mechanical ventilation to the patient during, guarantee that air flue is air tight, keep the stable device of airway pressure.
Background technology:
The respiratory failure that the various causes of disease cause need be carried out tracheal intubation, mechanical ventilation, so that keep patient's vital sign, for the treatment of the cause of disease provides time enough.Air flue nursing need during the mechanical ventilation is noted two problems: the airway secretions of first management of patients; Airway secretions needs clean through sputum aspirator tube or branchofiberoscope suction in time; Otherwise these secretions can adhere on the inwall of tracheal intubation owing to patient's cough, form the expectorant crust, also can cause airway secretions in the air flue retention, and the two not only influences ventilatory effect; And respirator dependency pneumonia can appear, influence therapeutic effect; It two is guarantee airway pressure stable, especially for having hypoxemia even adult respiratory distress syndrome occurs and have the patient of intrinsic positive end expiratory pressure, not only influences ventilatory effect like gas leakage repeatedly, and injury of lung can occur.Have at present and carry out the method that airway secretions removes during the wound mechanical ventilation and have: 1. temporary transient interrupt machine ventilation, from the close-by examples to those far off aspirate the secretions in tracheal intubation and the air flue with sputum aspirator tube or branchofiberoscope along tracheal intubation; 2. proceeded wound mechanical ventilation; Insert a connector in tracheal intubation and ventilating return junction; The aperture that an about 5mm of diameter is arranged on this connector; Open this aperture, sputum aspirator tube or branchofiberoscope get into air flue, and from the close-by examples to those far off aspirate the secretions in tracheal intubation and the air flue from this aperture; 3. proceeded wound mechanical ventilation; Insert a connector in tracheal intubation and ventilating return junction; This connector connects the sack that can stretch; The built-in sputum aspirator tube of sack, sputum aspirator tube gets into air flue, and from the close-by examples to those far off aspirates the secretions in tracheal intubation and the air flue through the aperture of connector.These three kinds of methods all can not fine solution be removed airway secretions and guaranteed the gastight problem of air flue.1st, there is gas leakage in 2 kinds of methods; The 3rd kind of method inhaled the expectorant poor effect, also has the periodic replacement gas leakage that sputum aspirator tube caused simultaneously.
Summary of the invention:
In order to realize to guarantee under the gastight situation of air flue during the mechanical ventilation; Remove airway secretions timely and effectively; The present invention provides a kind of wound mechanical ventilation air flue gastight device during removing secretions that can guarantee to have, and it is characterized in that: the circular hole of the about 10-20mm of a diameter is arranged on the connector between tracheal intubation and the ventilating return, be fixed with trilaminar at least elastic film on the circular hole; Thin film is close together; The small sircle hole of a diameter less than sputum aspirator tube and branchofiberoscope external diameter arranged respectively on each thin film, and the aperture of adjacent films has part to intersect, and the thin film aperture of the superiors and the bottom does not intersect.Like this, under the situation of not inhaling expectorant, because the thin film aperture of the superiors and the bottom does not intersect, air flue is gas leakage not; When inhaling expectorant; Because the aperture on the thin film is littler than the external diameter of sputum aspirator tube and branchofiberoscope; When sputum aspirator tube and branchofiberoscope pass through aperture; Elastic film is tightly restrainted around it, and different thin film are different to the direction of draw of sputum aspirator tube simultaneously, make between monolithic film membrane structure and sputum aspirator tube and branchofiberoscope can not leak air.In view of the above, this device can reach and guarantee the stable purpose that air flue leaks gas, guarantees airway pressure not occur during the timely and effective suction airway secretions.
The effect of patent of the present invention: according to above-mentioned construction features and functional characteristic, effectively remove airway secretions, guarantee that simultaneously air flue is air tight.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment patent of the present invention is further specified.
Fig. 1 is the connector of tracheal intubation and ventilating return.
Fig. 2 is the membrane structure cutaway view of circular hole on the connector.
Fig. 3 is the cutaway view that sputum aspirator tube or branchofiberoscope pass through the thin film aperture.
Among the figure: 1. the connector of tracheal intubation and ventilating return; 2. the circle on the connector; 3. the trilaminar at least elastic film that is adhered on the circular hole; 4. the roundlet on the thin film; 5. sputum aspirator tube or branchofiberoscope.
The specific embodiment
In Fig. 1, connector (1) one end links to each other with tracheal intubation, and the other end is connected with ventilating return, and the about 10-20mm of the circular hole on the connector (2) size has fixed at least three layers of elastic film of being close to each other (3) on the circular hole.
In Fig. 2, every layer film (3) has the aperture (4) of a diameter less than sputum aspirator tube or branchofiberoscope external diameter, and the aperture of adjacent films has intersection, and the thin film aperture of the superiors and the bottom does not intersect.
In the embodiment shown in fig. 3, sputum aspirator tube or branchofiberoscope (5) direction from the superiors toward bottom thin film (3) successively through behind the thin film aperture (4) of each layer, has not gas leakage between thin film (3) and sputum aspirator tube or branchofiberoscope (5) at least.
