Embodiment 1
[0042] see Figure 1-3As shown, a special surface anesthesia device for anesthesia laryngoscope provided by the embodiment of the present invention includes a handle 1 with a hollow inside, the shape of the handle is cylindrical, and the outside of the handle is covered with a rubber sleeve, which is suitable for the hand The shape is convenient to hold and operate. A laryngoscope 2 is detachably connected to one end of the handle 1, and here, the laryngoscope is detachably connected to the handle by screwing. The laryngoscope 2 is made of degradable materials. The degradable materials mainly include polylactic acid (PLA) with a molecular weight greater than or equal to 2 million and a reinforcing agent. The reinforcing agent is a blend of EMFORCEBIO and shell powder. After baking- High-speed mixing-granulation-drying-made by one injection molding. The degradable materials are all made of environmentally friendly materials. The anesthesia laryngoscope made of degradable mate...
Embodiment 2
[0054] see Figure 4-5 As shown, the difference from the above embodiment is that a speed control knob 10 is provided on one side of the power mechanism 11; a speed control rheostat 12 is connected to one end of the speed control knob 10 for adjusting the speed control rheostat 12 The size of the resistance value, the speed-regulating rheostat 12 is electrically connected with the micro-motor 111, by changing the resistance value on the speed-regulating rheostat, it can be used to change the current size in the circuit, thereby changing the speed of the output shaft on the micro-motor; power One side of the mechanism 11 is provided with a controller 13, and the controller 13 is electrically connected with the micromotor 111, and is used for controlling the starting of the micromotor 111 and controlling the rotation direction of the micromotor.
[0055] In this embodiment, the resistance value on the speed-regulating rheostat can be adjusted by turning the speed-regulating cont...
Embodiment 3
[0060] see Figure 6-9 As shown, the difference from the above embodiment is that the laryngoscope 2 includes a lens 21 and a lens 22, the lens 21 is detachably connected to the handle 1, the lens 21 is provided with a mounting hole 211, and one end of the lens 22 passes through the mounting hole 211, and is detachably connected to one end of the lens 21.
[0061] In this embodiment, the lens is detachably connected to the handle by screwing, the lower end of the handle is provided with an external thread, the upper end of the lens is provided with a hollow connecting pipe 214, and the inner wall of the connecting pipe is provided with a connection with the lower end of the handle. The external thread matches the internal thread, so that the lens can be detachably connected to the handle by screwing and rotating.
[0062] The lens is provided with a mounting hole 211 for installing the lens, a U-shaped buckle 221 is arranged on the end of the lens close to the connecting pipe...
