Example 4

As shown in fig. 4 and fig. 2b, the anti-extubation device comprises an instruction sending module, an extubation preventing module, a setting module 13, an automatic retraction device 23 and a buffer container 41 adjacent to the instruction sending module, wherein the instruction sending module comprises an element I21 and an element II 22, the extubation preventing module comprises a glove 1 and an air bag 6 which is arranged on the glove 1 and is provided with an inflation interface 5, the shape of the air bag 6 is similar to that of a palm, the air bag comprises a palm part and branches divided into five fingers, a puncture preformed hole 2 and a drip preformed hole 3 are formed in the corresponding position on the glove 1, the front end of the glove 1 is not closed, and each finger can be exposed after a patient wears the glove 1; the element II 22 is internally provided with a functional part which can sense the approaching and departing state between the element II and the element I21 and send a command to start the air pump to inflate and deflate the air bag 6; inside the automatic retraction device 23 are two clockwork spring attachment wheels 24.

In use, a medical staff passes a tube between two spring connecting wheels 24 in the fixed automatic retraction device 23 and makes the tube contact with the two spring connecting wheels 24, and the tube and the spring connecting wheels 24 have proper movable friction force, so that the tube can drive the spring connecting wheels 24 to rotate when a patient pulls outwards, the element II 22 is fixed on the automatic retraction device 23, and the element I21 is fixed on the tube which the patient wants to pull and is close to the element II 22; placing the tube between the patient intubation site 20 and the element II 22 (i.e., proximal segment) for an excess length as a buffer segment 40, the length of the buffer segment 40 being determined by the medical practitioner as a function of the actual condition, and may be 40cm, 50cm or other length, provided that the length is sufficient to ensure that the force of the patient during tube withdrawal does not act on the intubation site 20 and withdraw the tube from the body, placing the buffer segment 40 in a buffer container 41 that is fixed as close as possible to the intubation site 20; meanwhile, the glove 1 is worn on the hand of a patient for tube drawing and is fixed on the hand through a fixing belt buckle 30 of the wrist part 4, and the air pump is connected with the air inflation interface 5; while the setting module 13 is fixed to the glove 1.

During the use, when the patient takes the tube drawing action, because the buffer section 40 of the tube is placed in the buffer container 41, the patient can not draw the tube, and only can draw the tube from the section (namely the far-end section) fixed with the element I21, when the tube drawing is started, the buffer section 40 in the buffer container 41 is drawn out and passes through the two spring connecting wheels 24, the element I21 gradually gets away from the element II 22, when the element I21 and the element II 22 get away from each other by more than a set distance (the distance is temporarily set by the setting module 13 according to actual conditions before use and can be 10cm, 15cm or other), the element II 22 senses the away state and sends a command to start the air pump to inflate the air bag 6, and the inflated air bag 6 can limit the bending of the fingers of the patient so as to prevent the patient from drawing the tube.

The spring connecting wheel 24 is similar to a toy car seen by people at ordinary times, when the car is pulled backwards, the wheel rotates backwards to drive the spring to twist, the spring returns to the original state after the spring is released, the wheel rotates, and the car moves forwards. When a patient pulls out a tube, the tube moves to drive the spring connecting wheel 24 to rotate, after the patient releases the tube, the spring connecting wheel 24 rotates to retract the pulled tube, so that the automatic retraction device 23 retracts the pulled tube into the buffer container 41 adjacent to the tube, the element I21 approaches the element II 22, when the distance between the element I21 and the element II 22 exceeds the set distance and the approaching state continues for a certain set time (the time is temporarily set by the setting module 13 according to actual conditions before use and can be 5 seconds, 10 seconds or other times), the element II 22 senses the continuous approaching state and sends an instruction to deflate the air bag 6, and the deflated air bag does not limit the hand movement of the patient any more.

Due to the presence of the buffer section 40, it is avoided that the force of pulling the tube is applied to the intubation site 20 as soon as the patient starts, and thus the tube is prevented from being easily pulled out before the balloon 6 has been inflated, and in addition, the buffer section 40 prevents the tube from falling off the body when the patient moves to move the intubation site 20.

It is understood that the above only selectively illustrates some embodiments of the present invention, but not all embodiments of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, such as, for example, one element a 11\ element I21 paired with two or more elements b 12\ element II 22, one element b 12\ element II 22 paired with two or more elements a 11\ element I21, or the airbag 6 not fixed on the palm surface of the patient but fixed on the back of the hand, or the wind spring connecting wheel 24 in the automatic retraction device 23 not two, or even the automatic retraction device 23 not using the wind spring connecting wheel 24 mode but using other known modes that can achieve the same function, and so on, and these changes and modifications are all within the scope of the present invention.
