Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
Embodiment one
Fig. 1 is the structural representation of the glottis protection type endotracheal tube of the present embodiment.
As shown in Figure 1, glottis protection type endotracheal tube 100 comprises conduit 1 and gas-bag system 2.Conduit 1 comprises the tail end opening 11 and front opening 12 that is relative with tail end opening 11 and that insert in patient airway that are connected with anesthetic machine as respirator with aeration equipment, the cavity 14 that tail end opening 11, front opening 12 and catheter wall 13 enclose, defines the gas channel of glottis protection type endotracheal tube 100 jointly; Gas-bag system 2 comprises interior cuff 21 and outer cuff 22, interior cuff 21 encloses in conduit on the outer wall of front opening 12 side, outer cuff 22 one end is communicated with interior cuff 21 by the first fine duct 23, and the other end is connected with charger by air pressure valve 24 by the second fine duct 25.
Arrange the sunk area 14 of conduit 1 in interior cuff 21 away from conduit 1 front opening 12 side place, the length of sunk area 14 is 3cm-5cm, and sunk area bottom is 2cm apart from the distance of interior cuff 21.
Fig. 2 is the cross-sectional structure schematic diagram being inserted with the glottis of glottis protection type endotracheal tube of the present embodiment.
As shown in Figure 2, glottis 200 comprises vocal cords 10, vocal cords 20 and fissure of glottis 30, and the shape of cross section of sunk area 141 is rounded triangle, and the similar of fissure of glottis 30.
After glottis protection type endotracheal tube 100 in the present embodiment is inserted into trachea; open air pressure valve 24; by the second fine duct 25, outer cuff 22 and the second fine duct 23, interior cuff 21 is inflated; gap in glottis protection type endotracheal tube 100 and human body between trachea is blocked after inflating by interior cuff 21; be supported on inner surface of trachea and locate; then air pressure valve 24 cuts out, make interior cuff 21 and outer cuff 22 all keep inflated condition.Because interior cuff 21 and outer cuff 22 communicate, therefore the two air pressure is equal, and outer cuff 22 can react the pressure of interior cuff 21, when outer cuff 22 gas is not fully filled, the pipeline gas leakage between two cuffs is described, needs to change glottis protection type endotracheal tube 100.After ventilation terminates, open air pressure valve 24, the gas in interior cuff 21 is extracted out, so that taken out from narrow trachea by glottis protection type endotracheal tube 100.
Usually; adult male often selects internal diameter to be the glottis protection type endotracheal tube of 7.5mm; adult female selects internal diameter to be the glottis protection type endotracheal tube of 7.0mm; in the present embodiment, the parameter of sunk area is applicable to the glottis protection type endotracheal tube that adult uses; when being used on the glottis protection type endotracheal tube being suitable for child's use; sunk area bottom, can according to the reduction ratio of catheter diameter apart from the distance of outer cuff and this body length, and equal equal proportion reduces.
Embodiment effect and effect
According to the glottis protection type endotracheal tube that the present embodiment provides, comprise conduit and invest the cover bag system outside conduit, conduit comprises the tail end opening and front opening that is relative with tail end opening and that insert in patient airway that are connected with aeration equipment, the cavity that tail end opening, front opening and catheter wall enclose, defines the gas channel of glottis protection type endotracheal tube jointly; Cover bag system comprises and encloses cuff in conduit is on the outer wall of front opening; interior cuff is connected with aerating device by fine duct; because interior cuff arranges sunk area away from the pre-position of catheter proximal end opening side; the shape of cross section of sunk area and the similar of fissure of glottis; all triangular in shape; the glottis protection type endotracheal tube that the present embodiment is provided is when Clinical practice; sunk area is just in glottis position; the neither normal ventilation of impact, can not cause again the compressing of vocal cords and cause follow-up inflammation.
In the present embodiment, the shape of the cross section of sunk area is rounded triangle, and the shape of the cross section of sunk area can also be oval and Long Circle, sees variation one and variation two.
