Description

Drainage device capable of being submerged subcutaneously in neurology department

Technical Field

The invention relates to the technical field of medical instruments, in particular to a drainage device capable of diving under the skin in the neurology department.

Background

As is known, craniocerebral drainage has become a conventional treatment means for diseases such as craniocerebral trauma, cerebral hemorrhage, intracranial infection, hydrocephalus and the like, the drainage infection probability increases along with the prolonging of drainage time, and a fixed drainage catheter is arranged at a wound position in a subcutaneous way, so that the incidence rate of postoperative intracranial infection can be obviously reduced. At present, only a single-cavity drainage catheter can carry out subcutaneous sneak operation in craniocerebral drainage, and the single-cavity drainage catheter has no branch and has a smooth tail end, so that the single-cavity drainage catheter can be subcutaneously submerged to be far away from a wound fixing catheter after the catheter placement drainage is successful. The structure of the existing multi-cavity drainage tube is as follows: the medical tube is provided with a tube body, at least two cavities are arranged in the tube body, through holes communicated with the cavities are formed in the tube wall of the patient end of the tube body, branch tubes with the same number as the cavities are arranged at the end, far away from the patient, of the tube body, each branch tube is communicated with one cavity, and luer connectors, protective caps or heparin caps and other parts are arranged on the branch tubes for drainage, sampling, medicine injection and other operations. Because the end of the multi-cavity drainage tube far away from the patient is provided with at least two branch tubes, and the branch tubes are provided with parts such as a luer connector, a protective cap or a heparin cap and the like, the end far away from the patient cannot be smoothly connected with a hypodermic traction needle, and the subcutaneous sneaking operation cannot be finished. Forcefully subcutaneous undermining has great damage to tissues, and the clinical infection probability is increased.

For example, the multicavity drainage device with the application number of CN201410565482.5 which can be submerged under the skin realizes the function of minimally invasive drainage to the cranium after the subcutaneous submergence of the end of a patient of the multicavity drainage tube. However, it has the following problems: the connecting sleeve pipe generates larger force when being separated from the patient end of the multi-cavity drainage tube after subcutaneous sneak, so that the patient of the drainage tube is easy to feel obvious pain; the extra-arranged guide needle placing cavity reduces the aperture of a sampling cavity and a medicine injection cavity, the guide needle is placed in the cavity to carry out a tube placing operation, the guide needle is pulled out after the tube placing drainage is successful, and the speed is slowed down when the sampling or the medicine injection is carried out.
