Inner core bar for core bar of prefilled catheter irrigator

Abstract

The invention discloses an inner core bar for a core bar of a prefilled catheter irrigator. The inner core bar for the core bar of the prefilled catheter irrigator comprises an inner core bar body and an inner core bar handle; a radial medicine accommodating groove is formed in the side wall of the front end of the inner core bar body; a first sealing ring and a second sealing ring are formed in the outer wall of the inner core bar body; the rear end of the inner core bar body is arranged in the inner core bar handle; the space between the rear end of the inner core bar body and the inner core bar handle is provided with a first clamping groove, a second clamping groove and a clamping projection; and a third clamping projection is arranged on the inner core bar handle. The inner core bar and a corresponding outer core bar form the core bar; the core bar is used in a corresponding jacket; normal saline and medicines can be premixed; therapeutic medicines can be injected into a pipeline system when a pipeline is irrigated; and moreover, the medicines and the normal saline are mixed in the catheter irrigator, other puncture is not required, and pollution on the medicines is reduced greatly.

Description

technical field [0001] The invention relates to a medical device, in particular to an inner core rod used for the core rod of a prefilled catheter flusher. Background technique [0002] At present, after injecting drugs through the indwelling needle, normal saline is usually used to flush the indwelling needle catheter, but using normal saline can only perform simple pipeline flushing, which cannot play any therapeutic effect, and if you want to use normal saline with drugs If flushing is carried out, then in the process of dispensing, it is necessary to puncture the bottle stopper by dispensing, the rubber on the bottle stopper may produce debris in the process of puncturing and cause pollution to the medicine, which is not worth the candle. [0003] Therefore, how to realize the pre-mixing of physiological saline and medicine and infuse therapeutic medicine into the pipeline system during the process of flushing the pipeline is one of the problems that those skilled in the...
