Abstract

The invention discloses a clinical local anesthetic spraying device for anesthesiology department. The device comprises a handle and a needle cylinder, and further comprises: a driving mechanism fixedly connected to the top end of the handle; a supporting mechanism fixedly connected to the left side of the top end of the driving mechanism, wherein the needle cylinder is installed on the inner wall of the supporting mechanism; a piston inserted into the right side of the inner cavity of the needle cylinder in a left-right sliding manner; a baffle in threaded connection with the right end of the inner wall of the needle cylinder and located on the right side of the piston; and a quantitative boosting mechanism installed on the right side of the piston, wherein the quantitative boosting mechanism is driven by the driving mechanism to move left and right. According to the invention, quantitative drug application is achieved, the dosage of the sprayed local anesthetic is easy to control, and toxic and side effects caused by too large dosage of the anesthetic are prevented while the anesthetic effect is guaranteed; and the needle cylinder can be supported, so that the hand stability of an anesthetist during operation is facilitated, the accuracy of a spraying part is ensured, and the implementation of anesthesia operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a local anesthetic spraying device for clinical use in the department of anesthesiology. Background technique [0002] Topical anesthesia refers to the application of local anesthetics with strong penetrating power to the surface of the mucosa, so that it can pass through the mucosa and block the nerve endings located under the mucosa, so that the mucosa produces anesthesia, which is called topical anesthesia. This method is commonly used in superficial surgery or endoscopic examination of eyes, nose, throat, trachea, urethra, etc. Instillation method for eyes, coating method for nose, spray method for throat and trachea, and irrigation method for urethra; [0003] Commonly used drugs for topical anesthesia are tetracaine and lidocaine. These anesthetics have strong penetrating power, quick onset and long duration. When performing topical anesthesia, due to the small sp...
