Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of Multi-functional urethral catheter.
Background technique
Well known catheter is mainly made of natural rubber, silicon rubber or polyvinyl chloride (PVC) material, wherein mostly using
The silicon rubber of white clear makes catheter.
As is known in the industry, a kind of postoperative patient of aforementioned catheter is conventional under nursing and interfering and aseptically passes through
What urethral orifice insertion bladder was implemented to drain is widely used in postoperative, anesthesia and the medical devices of dysuriac.With prostate
It afterwards for patient, due to just finishing operation, thus is difficult to immediately restore normal voiding function, by plant catheter and need to retain
For a period of time, retention time length is determined by conditions of patients.
Be no lack of the technical information about catheter in disclosed Chinese patent literature, slightly with enumerate as
The pinpoint Foley catheter of CN202161458U(), a kind of catheter of CN104800957A(), CN207605217U(it is a kind of
Break-resistance double channel foley balloon indwelling catheter), a kind of band coating screw thread catheter of CN107497034A(), CN205885943U(it is a kind of
J-type catheter with reinforcing rib), a kind of opening type silica gel urethral catheter of CN201290794Y(), CN205411900U(portable
