Embodiment Construction

[0019] Such as Figure 1-Figure 8 The subcutaneously submerged multi-lumen drainage device shown is equipped with a multi-lumen drainage tube, from Figure 6 It can be seen from the figure that the structure of the multi-cavity drainage tube is provided with a tube body 3, and there are two cavities in the tube body 3, one cavity is a drainage cavity, and the other is a sampling and drug injection cavity. The end tube wall is provided with through holes 8 and 9 communicating with the cavity, and the end of the tube body 3 away from the patient is provided with two branch tubes respectively connected with the two cavities, and the end of the branch tube is provided with a Luer connector 5 or a heparin cap, Protective cap, branch pipe is provided with the tube clamp 4 of its on-off control; The quantity of cavity and branch pipe in the multi-cavity drainage tube body 3, and the aperture size of each cavity are determined by its function, and the structure of multi-cavity drainag...

Abstract

The invention discloses a multicavity drainage apparatus capable of moving under the skin and relates to the multicavity drainage device for neurologist craniocerebral drainage. The multicavity drainage apparatus is provided with a multicavity drainage tube, and is characterized in that a guided needle placement chamber is arranged in the tube wall of the patient end of the multicavity drainage tube, a guided needle extraction socket is arranged in the side wall, away from the patient end, of the guided needle placement chamber, and a guided needle is inserted in the guided needle placement chamber via the guided needle extraction socket; a connecting cannula sleeves the patient end of the multicavity drainage tube, a clamping protrusion matched with a through hole in the tube wall of the patient end of the multicavity drainage tube is arranged in the inside wall of the connecting cannula, and a traction needle is arranged at the front end of the connecting cannula. The multicavity drainage apparatus is simple in structure, convenient to use, accurate in implant position and capable of accurately implanting therapeutic targets; infection probabilities when the multicavity drainage tube is used for craniocerebral drainage are greatly reduced, and a function that the multicavity drainage tube performs minimally invasive operation on the brain after moving under the skin is realized.

Description

technical field [0001] The invention relates to a multi-cavity drainage device for craniocerebral drainage in the Department of Neurology, specifically a multi-cavity drainage device with simple structure, convenient use, precise implantation position, accurate implantation of treatment targets, and subcutaneous sneaking. Background technique [0002] We know that craniocerebral drainage has become a routine treatment for craniocerebral trauma, cerebral hemorrhage, intracranial infection, and hydrocephalus. Can significantly reduce the incidence of postoperative intracranial infection. At present, only the single-lumen drainage catheter can be subcutaneously operated in craniocerebral drainage. Because the single-lumen drainage catheter has no branch and the end is smooth, it can subcutaneously sneak away from the wound to fix the catheter after the catheter drainage is successful. The structure of the existing multi-cavity drainage tube is: a tube body is provided, at leas...
