Noninvasive anesthesia needle

Abstract

The invention discloses a needle for non-invasive anesthesia, which comprises a needle base and a needle tube arranged at the upper end of the needle base. The upper end of the needle tube is provided with a non-invasive anesthesia device. It is connected with the inner cavity of the needle tube, the non-invasive anesthesia device is a flat cuboid cavity, one of the flat surfaces of the flat cuboid cavity is an anesthesia surface, and the anesthesia surface is uniformly provided with a plurality of liquid outlets , the anesthesia surface is connected with a sponge block, the sponge block is consistent with the shape of the anesthesia surface and completely covers the multiple liquid outlet holes, and the non-invasive anesthesia device can also be a cylindrical cavity or a spherical cavity The cavity has the advantages of simple structure, low cost, safety and convenient use, and can help medical staff perform epidermal anesthesia or regional anesthesia for patients with quality and quantity.

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...

Problems solved by technology

[0003] Wherein, when performing epidermal anesthesia or regional anesthesia on human skin, anesthesia is generally sprayed onto human skin by spraying equipment for anesthesia. Existing spraying equipment is too large, inconvenient to use, and will increase the scope of anesthesia, wasting anesthetic drugs; In addition, in some small hospitals or community clinics, due to the cost problem, there is no spraying equipment, and the personal experience of the medical staff can only be used to apply, cover or fill the cotton wool soaked in anesthetic with tweezers for anesthesia, which is difficult to grasp. At the same time, the sharp tweezers will puncture the skin accidentally during operation, bringing new trauma to the patient
