Abstract

The invention relates to the field of medical treatment, in particular to an administration device control circuit for the otolaryngology department. The technical problem of the invention is to provide the administration device control circuit for the otolaryngology department, which can realize automatic control of drug administration amount and is convenient to use. According to the technical scheme, the control circuit comprises a second reflection type photoelectric switch circuit, a first reflection type photoelectric switch circuit, a first potentiometer, a second potentiometer and a switch control circuit, the output end of the second reflection type photoelectric switch circuit is connected with the input end of the switch control circuit, the output end of the first reflection type photoelectric switch circuit is connected with the input end of the switch control circuit. And through cooperation of a first potentiometer, a second potentiometer, a third potentiometer and a fourth potentiometer, medicine can be uniformly stored, so that a doctor can apply the medicine to a patient.

Description

technical field [0001] The invention relates to the medical field, in particular to a control circuit for an ophthalmic drug delivery device. Background technique [0002] Otolaryngology is the surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx, and related head and neck regions. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology, ear microsurgery, ear neurosurgery, lateral skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal surgery, etc. The emergence of neurosurgery (nose and skull base surgery), head and neck surgery, throat microsurgery, department of voice and speech disorders, and pediatric otolaryngology has greatly enriched the content of otolaryngology. [0003] At present, in otolaryngology medical treatment, it is often necessary to apply some therapeutic ointment in the ear cavity, nasal ...
