Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, and particularly relates to a probe-type medicine injector. Background Art

[0002] Respiratory department patients mainly include respiratory tract diseases and lung diseases. For patients with throat inflammation, anti-inflammatory drugs are usually needed to treat the throat inflammation.

[0003] Currently, when treating common diseases in the respiratory medicine department such as sore throat or tonsillitis, in order to better exert the efficacy of the drug, the drug needs to be directly applied to the painful area. Since the throat area is relatively narrow, it is not convenient to apply the medicine. And during the medicine application process, if the patient is stimulated due to improper operation, the patient's tongue will move involuntarily, which will affect the medicine application.

[0004] Therefore, we make improvements and propose a probe-type medicine injector. Summary of the Invention

[0005] The purpose of the utility model is to address the current situation that due to the relatively narrow throat area, it is not convenient to apply medicine, and during the medicine application process, if the patient is stimulated due to improper operation, the patient's tongue will move involuntarily, which will affect the medicine application.

[0018] In the solution of the present application:

[0019] 1. In order to solve the problems in the prior art that due to the relatively narrow throat area, it is not convenient to apply medicine, and during the process of applying medicine, if the operation is improper and stimulates the patient, the patient's tongue will move involuntarily and affect the application of medicine. In the present application, through the provided driving mechanism, the shifting mechanism can be operated.
