Catheter apparatus for neurosurgery department

Abstract

The invention discloses a catheter apparatus for the neurosurgery department. The catheter apparatus comprises an outer sleeve. Adhesive tapes are arranged on one side of the outer sleeve, and are fixedly connected with the upper surface of a fixed adhesive plate; a fixing unit is arranged in the middle of the upper surface of the fixed adhesive plate. A drainage tube and an infusion tube penetrate the outer sleeve; left ends of the drainage tube and the infusion tube are fixedly connected with the outer sleeve; the end, away from the outer sleeve, of the drainage tube is provided with a vacuum drainage bottle; a first flow-rate regulating valve is arranged on one side of the drainage pipe; a sealing plug is arranged at the end, away from the outer sleeve, of the infusion tube; a chemical inlet tube of the infusion tube is in snap connection with the sealing plug movably. The catheter apparatus for the neurosurgery department is of simple structure; the outer sleeve of the catheter apparatus can be regulated and positioned; the catheter apparatus is convenient to fix; drainage liquid and chemical liquid can be drained and delivered separately so that safety in use of the catheter apparatus is improved, infection to medical staff can be avoided and convenience in treatment is improved for medical staff. The catheter apparatus is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a neurosurgical catheter device. Background technique [0002] In clinical neurosurgery, especially when performing drainage operations, it is necessary to directly deliver therapeutic agents to specific targets in the brain through implanted catheters. At present, the catheters are too soft to be positioned accurately, and the catheters have poor fixation performance and are easy to fall off. When the drainage fluid is discharged, it is easy to cause problems such as infection of the medical staff by the drainage fluid, which brings great inconvenience to the treatment of the medical staff. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a neurosurgical catheter device, which can adjust and position the outer cannula, and the device is convenient to fix, and can discharge...
