Description

technical field

[0001] The invention belongs to the field of medical equipment, and in particular relates to a non-invasive anesthesia needle. Background technique

[0002] Anesthesia temporarily deprives the patient of the whole or part of the sensation through drugs or other methods, so as to achieve the purpose of painlessness, and provides conditions for surgical treatment or other medical examination and treatment, so as to avoid mental stress and reflex adverse reactions of the patient, thereby increasing the discomfort of the patient And pain, so that patients can undergo surgery or diagnostic medical examinations in a comfortable and quiet environment without responding to adverse stimuli and temporarily losing memory, so that patients can recover as soon as possible.

[0003] Among them, when performing epidermal anesthesia or regional anesthesia on human skin, the anesthetic is generally sprayed onto the human skin by spraying equipment for anesthesia. The existing...

Embodiment approach

[0032] see Figure 4 , the second embodiment provided by the present invention, specifically, the non-invasive anesthesia device 3 is a cylindrical cavity 35, and the cylindrical cavity 35 is used for regional and local anesthesia to special parts of the human body, such as the throat, nasal cavity, etc., and the cylindrical cavity The side wall of body cavity 35 is evenly provided with a plurality of liquid outlet holes 33, and the side wall of cylinder cavity 35 is connected with sponge ring 36, and sponge ring 36 is consistent with the side wall shape of cylinder cavity 35 and multiple The outlet hole 33 is completely covered.

[0033] More specifically, the ring width of the sponge ring 36 is 3-5 mm. Generally, the sponge ring 36 is set to 5 mm. The thickness of 5 mm is convenient for different groups of people to use to ensure the anesthesia effect. The internal space of other parts will also be different. On the other hand, the sponge ring 36 has been extruded by the th...
