Description

Portable nasal medicine device

Technical Field

The invention belongs to the technical field of medical equipment or medicine management and control devices, and particularly relates to a portable nasal medicine device suitable for multiple occasions such as families, hospitals, public emergency, disaster relief and the like.

Background

Clinically, when a doctor performs an otorhinolaryngological operation, the doctor often needs to perform surface anesthesia on a patient so as to relieve pain of the patient and improve the success rate of the operation. However, in clinical practice, there is a lack of suitable medical apparatus dedicated to surface anesthesia, and most of clinicians use simple combination of syringe and spray tube, or use form of applying anesthetic ointment, and temporary combination is needed before use, which is very unfavorable for doctors to operate, and the dosage of medicine is difficult to measure and control.

Thereafter, nasal administration by spraying is sought. However, for nasal administration, there are often some specific application scenarios. For example: the patient needs to use a plurality of spray agents in sequence to finish the combined administration of a plurality of medicines. For this application scenario, it is currently common practice to: the medical staff or the patient holds the independent spray type medicine bottles of each medicament in sequence and carries out spray type administration through the nasal cavity in sequence.

From the above, the operation mode and the corresponding apparatus for nasal administration at present are very complicated for medical staff and patients, are inconvenient for standardized operation, and the dosage of the medicine is not easy to control, so that the application scene is also greatly limited. In particular, children are more difficult to effectively implement or have a greater risk in practice due to subjective mismatch.
