Abstract
The utility model discloses a nasal cavity anesthesia tool, which comprises an injection tube, wherein anesthetic holes are distributed around the injection tube, a sponge cylinder is wrapped around the injection tube, and an injector is connected to the tail of the injection tube. When the anesthetic is used, anesthetic is injected into the injection tube through the injector and flows out from the anesthetic hole, the sponge cylinder can be adsorbed with anesthetic liquid, then the sponge cylinder is inserted into the nasal cavity, and the medicine can be continuously added through the injector according to clinical needs, so that mucous membrane in the nasal cavity is always in a liquid medicine infiltration state in the anesthetic process, and the sponge cylinder is pulled out and discarded after the surface anesthetic effect is achieved. The utility model has the characteristics of simple structure and easy operation.
Description
Technical Field
The utility model relates to the technical field of nasal cavity anesthesia, in particular to a nasal cavity anesthesia tool.
Background
Before nasal tracheal intubation, the nasal cavity needs to be subjected to surface anesthesia, and meanwhile, the nasal mucosa blood vessel is contracted, so that discomfort and nasal mucosa hemorrhage of a patient in the intubation process are prevented. At present, the anesthetist dips a medical cotton stick into a surface anesthetic and a vasoconstrictor medicine, and then plugs the surface anesthetic and the vasoconstrictor medicine into the nasal cavity, so that the liquid medicine fully contacts and infiltrates the nasal mucosa for 3-5 minutes, and the effects of surface anesthetizing the nasal mucosa and vasoconstrictor blood vessels of the nasal mucosa are achieved. The method has 3 defects, namely, the anesthesia effect cannot be ensured because the medical cotton sticks have fewer cotton quantity, limited adhesion to medicines and limited storable anesthetic medicine quantity; on the other hand, the medical cotton stick is in a hammer shape, cannot be well attached to a nasal passage bent in a nasal cavity, and can not be infiltrated by liquid medicine due to the fact that part of nasal mucosa cannot be infiltrated, so that the anesthesia effect is poor. In addition, in the process of taking out the medical cotton swab, the cotton part can be hooked with structures such as nasal hair, so that the cotton part is separated from the swab, and the cotton part stays in the nasal cavity of a patient, so that the taking out is difficult, and the patient is damaged.
Disclosure of Invention
In order to solve the technical problems, the utility model provides the following technical scheme:
the utility model relates to a nasal cavity anesthesia tool, which comprises an injection tube, wherein anesthetic holes are distributed around the injection tube, a sponge cylinder is wrapped around the injection tube, and an injector is connected to the tail of the injection tube.
As a preferable technical scheme of the utility model, the injection tube and the sponge cylinder are fixed through a positioning mechanism.
As a preferable technical scheme of the utility model, the positioning mechanism comprises a jack which is arranged on the sponge cylinder and is used for inserting the front end of the injection tube, the jack does not penetrate through the sponge cylinder, and the joint of the port of the jack and the injection tube is fixed through a waterproof adhesive layer.
As a preferable technical scheme of the utility model, the front end part of the sponge cylinder is arc-shaped.
As a preferable technical scheme of the utility model, the end of the injection tube is provided with a one-way liquid inlet valve.
