Abstract

The invention relates to the technical field of medical instruments, and discloses a drainage catheter, a drainage device and a drainage method. The drainage catheter comprises: a main catheter body, wherein the main catheter body comprises a drainage end and a connecting end, and a first channel penetrating through the drainage end and the connecting end is formed in the catheter body; a connector, which is detachably connected to the connecting end, wherein a second channel is formed in the connector; and an adapter assembly, which is arranged at the connecting end in a sleeving mode, abuts against the connector and communicates with the catheter body, wherein the first channel communicates with the second channel, and a drainage cavity is formed. According to the drainage catheter, body fluid drainage can be carried out at a focus through the drainage end; and the connecting head and a switching assembly are detachably connected to the connecting end, so the connecting end can be connected with the connecting head and the switching assembly after passing through a subcutaneous tunnel, the probability of catheter disengagement is reduced, infection risks are decreased, and the technical problem that an existing multi-cavity drainage catheter cannot conduct drainage through a subcutaneous tunnel is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage catheter, a drainage device and a drainage method. Background technique [0002] External drainage of cerebrospinal fluid is one of the most commonly used therapeutic techniques in neurosurgery. The traditional drainage method is to insert a drainage catheter directly at the craniocerebral puncture point, which is easy to cause wound infection, and the drainage tube cannot be fixed and may be easily detached. Therefore, by establishing a subcutaneous tunnel so that there is a certain distance between the scalp puncture point and the outlet of the drainage catheter, the outlet of the drainage catheter can be transferred to a more suitable and favorable position. The puncture point communicates with the outlet of the drainage catheter through a subcutaneous tunnel, and the subcutaneous tunnel itself forms a barrier to prevent infection, which can effectively prev...
