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...

Abstract

The invention provides a special surface anesthesia device for anesthesia laryngoscope, which includes a handle with a hollow inside. There is a reciprocating pressurizing mechanism, one end of the pressurizing mechanism is provided with a liquid inlet and a liquid outlet, and the said pressurizing mechanism sucks the anesthetic liquid through the liquid inlet through the reciprocating motion, and then sprays it through the liquid outlet. Out; the side of the liquid outlet away from the pressurizing mechanism is provided with an atomizer, one side of the atomizer is detachably connected with a spray pipe, and one end of the spray pipe is connected with an atomizing nozzle; The spray tube is clamped on one side of the laryngoscope. The reciprocating pressurizing device makes the liquid medicine in the chamber squeeze out through the liquid outlet, atomize the liquid through the atomizer, and spray it out continuously and evenly to improve the anesthesia effect; and a degradable disposable laryngoscope is used, Avoid the occurrence of cross-infection, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of anesthesia laryngoscope, in particular to a special surface anesthesia device for anesthesia laryngoscope. Background technique [0002] Anesthesia laryngoscope is an auxiliary device used for tracheal intubation. It needs to enter from the oral cavity and reach the glottis through the deep part of the pharynx. Although the anesthesia laryngoscope does not touch the tongue, tonsils and other parts in this part, it still occurs. Stress reactions such as vomiting or swallowing reflex, which affect laryngoscopy, may even bring other adverse consequences. Therefore, when performing tracheal intubation with anesthesia laryngoscope, it is necessary to apply topical anesthesia to the glottis in the deep pharynx. [0003] At present, for the equipment for laryngeal anesthesia, the laryngeal sprayer is usually used to anesthetize the glottis surface, while the existing laryngeal sprayer mostly uses manual extrusi...
