The utility model connects with the external thread of the drug hose orifice through the internal thread of the connecting part, so that the injection tube injects the ointment to the required administration place; the internal thread of connecting portion is the step face, is less than the diameter of keeping away from the injection tube end near the diameter of injection tube one end, can adapt to the external screw thread of not unidimensional medicine hose mouth, and application scope is wide.
Description
Technical Field
The present utility model relates to the field of medical devices, and more particularly to a disposable injection head for administration in the ear canal, the nail slit.
Background
At present, narrow channels such as auditory meatus, nail slits and the like have no special drug delivery device in the slits. In general, medical staff administer the medicine with a cotton swab or modify a syringe needle, so that the operation is inconvenient and the administration effect is poor.
Disclosure of Invention
The utility model aims at solving the problems of inconvenient administration and poor effect of auditory meatus and nail slot administration and provides a disposable injection head for auditory meatus and nail slot administration.
The technical scheme of the utility model is as follows:
the utility model provides a disposable injection head for administration of auditory meatus and nail suture, which comprises an injection tube and a connecting part, wherein the injection tube is connected with the connecting part and internally communicated with the connecting part; the connecting part is provided with an internal thread and is matched with an external thread of the drug hose orifice.
Further, the outer side wall of the connecting part is provided with an anti-slip convex edge.
Further, the length of the injection tube is 31-40mm.
Further, the diameter of the injection tube is 1.2mm.
Further, the injection tube and the connecting part are integrally formed by adopting a silicone tube.
Further, the injection tube adopts a steel needle tube.
Further, the front end of the injection tube is open, and the opening is elliptical.
Further, the internal thread of the connecting part is a step surface, and the diameter of one end close to the injection tube is smaller than the diameter of the other end far away from the injection tube.
The utility model has the beneficial effects that:
the disposable injection head for the administration of the auditory meatus and the nail slot is connected with the external thread of the soft orifice of the medicine through the internal thread of the connecting part, and the ointment is injected to the required administration position through the injection tube; the internal thread of connecting portion is the step face, is less than the diameter of keeping away from the injection tube end near the diameter of injection tube one end, can adapt to the external screw thread of not unidimensional medicine hose mouth, and application scope is wide.
The injection tube and the connecting part are integrally formed by adopting a silicone tube; or the injection tube adopts a steel needle tube, thereby facilitating the administration.
The front end of the injection tube is open, and the opening is elliptical, so that the injection tube can be conveniently administered into a narrow gap of a nail canal to reach an affected part.
Additional features and advantages of the utility model will be set forth in the detailed description which follows.
