the main problems solved by this embodiment are: the displacement action of the catheter inner core 2 and the friction of the inner wall of the trachea are utilized to realize the smearing of the lubricating liquid at the dry part of the inner wall of the trachea, and meanwhile, the inflation process of the air bag is completed when the catheter is pulled out, so that the problems that the lubricating liquid smeared on the outer wall of the catheter is consumed greatly and cannot adhere to the bottom of the trachea, and the inflation pressure cannot be constant are solved.
In a second embodiment, a method for using a visual tracheal cannula is provided, including the following steps:
s1: the early installation process comprises the following steps: the inner core hose 201 is inserted into the outer wall 101 of the catheter and the head part of the inner core hose is penetrated out of the front end, the decompression assembly 203 is fixed at the head part of the inner core hose 201, the direction-adjusting toothed bar 207 is connected with the guide assembly 6, the head data wire of the USB interface 5 is connected, at the moment, the inner core hose 201 is pulled towards the tail part, the positioning clamping block 2042 is blocked at the position of the inner wall clamping block 103, the tail part decompression assembly 203 protrudes out of one end of the outer wall 101 of the catheter, the constant pressure bag 11 is arranged, the inner core rod 202 cannot slide towards the front end, and the USB interface 5 is arranged and the end part of the constant pressure bag is connected to the display screen.
S2: catheterization procedure: the catheter formed by the above processes is inserted into the trachea deep of a patient, the real-time position of the catheter head is displayed through the display screen, when the catheter head is positioned at the drier inner wall, the catheter head is contacted with the displacement ball 7 inevitably in the expanding process under the action of the outer pan head 206 due to the fact that the viscosity of the inner wall of the trachea is large, and the displacement ball 7 rotates to smear water-soluble lubricating liquid in the liquid storage tube 8 to the inner wall of the trachea when contacting the displacement ball, so that the subsequent part of the catheter is lubricated.
S3: catheter adjustment process: when fine position adjustment is needed, the steering knob 602 is rotated, the steering rack 207 drives the rotary disk 9 to enable the edge action rod of the steering rack to slide at the tail of the liquid storage tube 8 to push the displacement balls 7 to move towards the head, and as the front and rear positions of the displacement balls 7 are different, the guide tube slightly moves towards the extending side of the displacement balls 7 under the friction action of the inner wall of the air tube, so that the effect of head adjustment is achieved.
S4: the inner core is pulled out: after reaching the designated position and finishing the detection, the inner core hose 201 is pulled out outwards, the inner core hose 201 drives the decompression assembly 203 to move in the inflation assembly 204, the inflation assembly 204 is in a fixed state under the action of the inner wall clamping block 103, the head rod 2031 moves in the inflation assembly 204 and transmits gas to the inner part of the outer wall air bag 301 through the inflation hole 303, the guide rod 2033 moves when being contacted with the air bag stop 2043 and is fixed on the inner side of the inflation hole 303 under the action of the inclined plane to play a role of sealing, at the moment, the inner part of the air bag assembly 3 finishes the inflation process to fix the guide pipe, meanwhile, the guide rod 2033 contacts with the positioning clamping block 2042 and contracts in the groove, the inner wall clamping block 103 loses the fixing effect and slides in the groove, the inflation assembly 204 is pulled out of the guide pipe under the action of the inner core hose 201, and the decompression assembly 203 is separated from the inner core hose 201 to be disinfected, washed, stored and stored.
Secondly, the problem that the pressure of the air bag cannot be constant and the detection mode is complex is solved;
after the gas of the inflation assembly 204 enters the outer wall airbag 301, because the constant pressure bag 11 adopts a constant pressure structure, when the internal pressure of the outer wall airbag 301 is high, the redundant gas can enter the inner part of the constant pressure bag 11 through the gas regulating hole 302 and expand the constant pressure bag, so that the effect of stabilizing the internal pressure is achieved.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
