On original tracheal casing pipe basis, increase cap, oxygen hose and minim pipette are inserted respectively in the oxygen pore and dropper hole of cap, by the aperture in oxygen pore and dropper hole is rationally set, thereby make oxygen hose and minim pipette self-locking, fixation is reliable.Oxygen hose and minim pipette insert after designated depth, and lower cover is threaded with the socket cap of inner sleeve, because lower cover can freely rotate relative to upper cover, while being screwed into, keep upper cover motionless, and lower cover is screwed into, and avoid oxygen hose and minim pipette shift in position.After being screwed into, the stage portion of upper cover below is pressed in inner sleeve upper surface, thereby upper cover is fixed.Dropper hole, oxygen pore edgewise portion arrange, and the enough sputum aspirator tubes of center-aisle insert.
Described dropper hole, oxygen pore are inverted trapezoidal, and its lower end bore is less than upper end bore, when minim pipette and oxygen hose insert from top to bottom, by guide channel, can insert easily, and lower port footpath is automatically by minim pipette and oxygen hose locking simultaneously.
Described oxygen pore lower port footpath is less than 10mm, and lower end, dropper hole bore is less than 4.5mm, preferred oxygen pore lower port footpath 9mm, and lower end, dropper hole bore 3.5mm, is all less than oxygen hose and the minim pipette external diameter of standard specifications.
Described trocar sheath comprises outer tube body, dished head, and dished head two ends are provided with symmetrical setting fastening, and in the middle of it, installing hole one side is provided with bayonet lock, connects frenulum, thereby trocar sheath is fixed on to patient's incision by setting fastening, limits inner sleeve rotate by bayonet lock.
Described inner sleeve comprises interior tube body, head chuck, connecting cylinder head in the middle of chuck, socket cap outside is provided with external screw thread, chuck one side is provided with arc notch, socket cap is connected with the female thread of lower cover by external screw thread, the arc notch of chuck coordinates with the bayonet lock on trocar sheath, the rotation of restriction inner sleeve.
Also comprise blanking cover, blanking cover closed upper part, its inner side is provided with screw thread, during client need second wind, blanking cover is screwed on inner sleeve, thus sealing gas tube orifice, good sealing effect.
During use, trocar sheath is fixed on to patient's neck place, inner sleeve is inserted in trocar sheath, by bayonet lock, coordinate with arc notch, place inner sleeve and rotate.Minim pipette, oxygen hose are inserted respectively in the dropper hole, oxygen pore of cap, insertion depth is 6～8cm approximately, cap is placed on inner sleeve together with minim pipette, oxygen hose, keep upper cover motionless, rotation lower cover, lower cover is screwed on the socket cap of inner sleeve, tightens rear upper cover stage portion and socket cap end and compress, make cover locking.While needing suction sputum, sputum aspirator tube is inserted from middle passage.While carrying out cleaning-nursing, lower cover is screwed off, lower cover is taken out together with minim pipette, oxygen hose simultaneously, minim pipette, oxygen hose, without covering and take off from down, after having cleared up, are screwed onto lower cover on inner sleeve again, and easy accessibility, greatly reduces work load.
Compared with prior art, the beneficial effects of the utility model are:
This tracheal cannula device is simple in structure, installs and convenience easy to use, and the dismounting of intubate is rapid, and fixed form is reliable, greatly reduces nursing burden, ensures patients ' lives safety; By blanking cover is set, improve sealing effectiveness, be conducive to patient's second wind.
