Technical Field
The invention relates to the technical field of medical instruments, in particular to a local anesthetic spraying device for clinical use in an anesthesia department.
Background
Topical anesthesia refers to the phenomenon of local anesthesia, called topical anesthesia, in which a local anesthetic having a high penetration force is applied to the surface of a mucous membrane so as to penetrate the mucous membrane and block nerve endings located under the mucous membrane, thereby inducing anesthesia in the mucous membrane. This is commonly used in superficial surgery or endoscopy of the eye, nose, throat, trachea, urethra, etc. Eye drop, nasal application, throat and trachea spray, and urethra irrigation;
the common medicines for surface anesthesia comprise tetracaine and lidocaine, and the anesthetics have strong permeability, quick response and long duration. When the surface anesthesia is implemented, because the local anesthetic spraying area is small, a better anesthesia effect can be achieved while a smaller dosage is used, and smooth implementation of mucosa superficial surgery, invasive examination, operation and the like is guaranteed. However, topical anesthesia methods also have deficiencies and improvements. Because the local anesthetic is usually specific to a mucosa sensitive part, in the spraying process, no device or method is available at present for accurately and quantitatively using the drug dosage of the local anesthetic, the spraying dosage cannot be controlled, and once the dosage is too large, toxic and side effects caused by the excessive dosage of the local anesthetic or tissue damage of the anesthetized part are easily caused. For example, for the eye and other relatively delicate human tissues, the suspension dripping mode can be adopted at present, the medicine dripping device cannot be fixed during dripping, the medicine dosage cannot be accurate, and the medicine dripping accuracy and the medicine dripping effect are all left to be improved. Therefore, there is a need for a local anesthetic spraying device that is convenient for clinical use by anesthesiologists to achieve accurate anesthesia.
