The data of the communication modes such as WIFI, bluetooth are transmitted.In addition, the display screen can be but be not limited to bendable transparent screen.
It should be noted that intubation positioning system provided herein can effectively provide the accurate of internal intubation
Rate reduces the generation of Mala praxis.In addition, though increasing magnetisable coating outside intubation, but original insert can't be changed
The size of pipe caliber.Since intubation is not related to any circuit design, intubation provided herein not will increase the pain of patient,
And safety also available guarantee.For hospital, increase magnetisable coating outside intubation, existing equipment will not be made
At influence, and cost is relatively low；And since magnetisable coating belongs to weak magnetic, the facilities and equipment of hospital will not be produced
Raw any interference.
In addition it is also necessary to explanation, positioning unit and in vivo intubation can be achieved be wirelessly connected, and support based on WIFI,
The data of the communication modes such as bluetooth are transmitted, real-time, intuitive, convenient, fast.In addition, positioning unit compact, according to work need
It wanting, doctor is hand-holdable to be monitored positioning, and it also could be adhered to patient body and positioned, the hardly change existing work of doctor
Process, simple easy to get started, the old and new doctor is easily mastered, with good application prospect.
