The flexible arm motor a-4 of the present embodiment is driven and controlled by a flexible arm driver a-5.

The working principle of the present invention is explained with reference to fig. 1 to 15:

the structure of the oxygen mask fastening system of the present invention, when the knob 4-5 on the control panel C-1 is rotated, the analog voltage transmitted to the driver 1-1 through the potentiometer is proportionally changed. According to different voltages, the torque value of the fastening motor B-1 controlled by the driver 1-1 is also changed proportionally. The fastening motor B-1 drives the double-wire groove guide wheel B-3 to rotate, the steel wire ropes coming out of the double-wire groove guide wheel B-3 are transmitted and turned through the auxiliary wire guide wheel assembly F and the single-wire groove wire guide wheel assembly D, and the steel wire ropes 1-6 on the left side and the right side move by the same stroke, so that the fastening pressure of the oxygen mask is adjusted.

When the flexible arm is fastened in the use process, the motor moves towards a set moment value in a moment mode to drive the worm gear to rotate, the worm gear drives the guide bolt to move downwards through threaded connection, and then the steel wire rope is tensioned with a certain moment value, so that the flexible arms on the left side and the right side keep a certain shape; when the snake-shaped arm is loosened, the motor moves in the opposite direction in a moment mode, the worm wheel and the worm are driven to rotate, the worm wheel drives the guide bolt to move upwards through threaded connection, and then the gradual loosening of the steel wire rope is realized, so that the left flexible arm and the right flexible arm are gradually loosened; to stop the snake-shaped arm from loosening or tightening, the motors on the left side and the right side can be stopped from the previous state by pressing a 'tightening' button or a 'loosening' button on the soft operation panel. Meanwhile, the snake-shaped arm is provided with the RFID magnetic sheet, the using times of the snake-shaped arm can be restrained within a certain range by identifying the magnetic sheet and recording the using times of the snake-shaped arm, and the safety coefficient of the snake-shaped arm is greatly improved.

The logic of the control system in the anesthesia airway assistance management appliance of the present invention is shown in FIG. 15. Adjustment of the fastening pressure of the oxygen mask, implementation: after the power switch 4-3 is powered on, the oxygen mask is closed to enable the motor to be opened. The knob adjusting potential knob 4-5 transmits a voltage transformation signal to the driver 1-1 of the oxygen mask fastening system through an analog signal, and sends a corresponding current value to the fastening motor 1-2 (the fastening motor B-1) according to the number read by the driver 1-1. The tightness control of the soft operation panel 4-1 is realized by the following steps: the "loose" button and the "tight" button cannot turn green at the same time, and need to be interlocked, and are controlled and implemented by the program of the control boards 4-7. Implementation mode of snakelike arm elasticity function: when the "tight" button on the soft control panel 4-1 is pressed, and when the alarm signal of the control panel timing circuit is not received, the driver 2-1 (the flexible arm driver A-5) sends a forward current value to the motor 2-2 (the flexible arm motor A-4). When the "loose" button on the soft control panel 4-1 is pressed, the driver 2-1 sends a negative current value to the motor 2-2.

Implementation mode of serpentine arm counting function: when the control board 4-7 detects that the "tight" button on the soft operation panel 4-1 is pressed and the actual current value is larger than the set value, the driver 2-1 sends a high level signal to the timing circuit board of the control board 4-7. An RFID magnetic sheet A-7 is hung outside the serpentine arm 2, and if the magnetic sheet A-7 is identified by the timing circuit, the timing circuit 4-7 starts timing. When the control board 4-7 detects that the loose button on the soft control panel 4-1 is pressed, a low-level signal is sent to the timing circuit board, and timing is stopped; when the power supply 4-3 is powered down, the timing circuit board stops timing. If one time reaches the set time, the count is incremented by 1.

The serpentine arm uses the digital display of the number of times, the implementation mode: the remaining times of the serpentine arm used by the timing circuit are displayed through the digital display panel 4-2; when the power is on, the left magnetic sheet A-7 and the right magnetic sheet A-7 are completely identified, and the digital display panel 4-2 can normally display the corresponding residual times; when power is on, the left magnetic sheet A-7 and the right magnetic sheet A-7 are not completely identified, and the digital display panel 4-2 displays the residual times as 0; in the electrifying process, two magnetic sheets A-7 are suddenly lost, and the number of the remaining display times of the digital display panel 4-2 is kept unchanged; when the remaining number is 0, an alarm signal is sent to the driver 2-1.

The working process of the anesthesia airway auxiliary management instrument comprises the following steps:

serpentine arm mounting: the two serpentine arms are lowered in alignment with the mounting holes and the two RFID tags a-7 are pressed into the bayonet. Pressing the bright tight button to enable the snake-shaped arm to be installed downwards for fastening, and pressing the tight button after 5-10 seconds to complete the installation.

Mask guy wire rope installation: the electric potential knob 4-5 of the mask is adjusted to the 0 position, two ends of a disposable rope are connected with the steel wire rope hooks, the middle part of the rope is hung into the groove slideway at the front end of the mask base, and the installation of the rope of the mask is completed.

When in use, the device is placed on the head side of an operating table, a patient lies on the back at the corresponding position of the base of the mechanical system, and a proper amount of analgesic and sedative is given to enable the patient to be in a sedated state (note: the connecting line of the earlobe of the two sides of the patient is basically coincident with the connecting line of the root parts of the snake-shaped arms of the two sides).

The power switch 4-3 is pressed to power up the electrical system.

Pressing the "loose" button, starting the motor 2-2 for 5-10 seconds, and after the snake-shaped arm reaches proper softness, pressing the "loose" button again, so that the snake-shaped arm 2 is in a loose standby state.

The anesthesiologist orders the patient to lean back the head, evaluates in advance whether the hand supporting part A-3 of the snake-shaped arm can be well attached to the mandibular posterior branch (the position between the mandibular angle and the earlobe) of the patient, if the attachment is not good, the purpose can be achieved by adjusting the front and back positions of the base of the system.

Opening the device to be 'tight' (simultaneously 'loose' and automatically closing), then using both hands to simultaneously attach the hand supporting parts A-3 of the two side snake-shaped arms to the corresponding parts of the back branches of the lower jaw of the patient, supporting the lower jaw of the patient, keeping the airway of the patient in a smooth state, and enabling the snake-shaped arms to reach a preset locking state after about 20-30 seconds (if the locking force is insufficient, the system automatically starts a motor to strengthen the locking of the snake-shaped arms).

The anesthetic mask with the corresponding model is selected to be horizontally placed on the jaw face of a patient, mask ropes on two sides are respectively hung on mask hooks on the left side and the right side, the potential knob 4-5 is rotated to a certain target torque position (the target torque can be selected according to the sealing effect of the mask) so that the mask ropes are tensioned, and meanwhile, the front-back inclination angle of the mask can be adjusted through manual assistance.

After confirming that the tightness of the mask and the unobstructed state of the patient airway are good, the general anesthesia induction is started, and then the noninvasive mechanical ventilation is implemented, so that the general anesthesia operation is maintained.

After the operation is finished and the anesthesia is awake, the potential knob 4-5 is rotated to the 0 position, the mask rope is rotated to a loose state, and the mask buckling state is released.

The "loose" preset button is turned on (while the "tight" automatic turn-off) and the locking motor 2-2 will rotate in the opposite direction, so that the snake-shaped arm is in the loose standby state again, the jaw supporting state is released, and the "loose" button is pressed again.

And (3) finishing one-time use, and pressing the power switch 4-3 to power down the electrical system.

Disassembling the serpentine arm 2: the two serpentine arms are disassembled together. The magnetic sheet A-7 is detached from the bayonet, the locking nut cap is screwed out, the loosening button is pressed down, the motor 2-2 is started for 20-30 seconds, the snake-shaped arm can be simultaneously withdrawn, and then the loosening button is pressed down.

Serpentine arm risk treatment: if the snake-shaped arm is rapidly required to be taken off in the operation process, the hand breaks the snake-shaped arm outwards, and the mandibular state of the snake-shaped arm can be relieved.

Mask string risk management: the selected rope has certain elasticity, and if the oxygen mask is rapidly pulled away in the operation process, the human hand can pull off the mask wire, and the mask buckling state is released.
