The utility model relates to a ventricle drainage tube including a tube body, a tube head and a tube core, the tube head is in the shape of a bullet, a plurality of side holes are arranged on the side wall of the tube body behind the tube head, and the tube core is arranged in the cavity of the tube body, and the tube provided is characterized in that a channel is arranged in the tube head, one end of the channel is communicated with the cavity of the pipe body, the other end of the channel is communicated to the outside vie the end of the tube head; the inner side wall of the tube body, which is behind the side holes, is provided with a projection to form into a valve seat, the front part of the tube core is provided with a tip cone to form into a valve core. Arranging a valve behind the side holes, the liquid leakage can be prevented during the insertion of the ventricle drainage tube and the tube core is easy to pull out; the drainage is more thorough by arranging the channel at the tube head; moreover, the scale provided facilitates in the assurance of the insertion depth of the ventricle drainage tube; and the handle provided is more convenient for the insertion and pull-out of the tube core.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of ventricular drainage tube.
Background technology
In the past, employed ventricular drainage tube generally comprises body and tube head in the ventricular drainage operation, and tube head is bullet shape, the end seal of tube head, and the tube wall that is in the tube head rear is provided with a plurality of side openings, uses for drain.This drainage tube is because body is soft, be difficult to puncture into patient's the ventricles of the brain, need repeatedly make repeated attempts, cause suffering and cause infection easily to the patient, in the process of inserting patient's ventricles of the brain, the liquid of patient's ventricles of the brain can flow in the cavity of body through side opening, and flows out from the other end of body, pollute easily, need handled.
In order to solve the problem that above-mentioned ventricular drainage tube is difficult to puncture into patient's ventricles of the brain, a kind of novel drainage tube has appearred at present, the body of this novel drainage tube and tube head are with former the same, its improvements are also to be provided with tube core, and tube core is in the cavity of body, and tube core plays the effect of the intensity of strengthening ventricular drainage tube, be convenient to puncture, when ventricular drainage tube is inserted into the precalculated position, extract tube core, the suction that is produced when extracting tube core more helps the drain of clot in the ventricles of the brain.Yet, also there is following defective in this novel ventricular drainage tube: one, the end of the tube head of ventricular drainage tube is the position of going deep into most that enters patient's ventricles of the brain, but because the end seal of tube head can't drain be in liquid and the clot that gos deep into the position most, drain is not thorough; If it is too tight that tube core contacts with the inwall of body, then ventricular drainage tube is difficult to extract tube core after inserting, if tube core does not closely contact with the inwall of body, then in the process of inserting patient's ventricles of the brain, still having liquid can flow in the cavity of body through side opening, and flow out from the other end of body, pollute easily; In addition, the length that ventricular drainage tube inserts is difficult to accurate judgement, can only lean on range estimation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ventricular drainage tube, and this ventricular drainage tube inserts easily, has both prevented that liquid spilt during insertion, extract tube core again easily, and drain is more thorough.The technical scheme that adopts is as follows:
A kind of ventricular drainage tube, comprise body, tube head and tube core, tube head is bullet shape, the tube wall that is in the tube head rear is provided with a plurality of side openings, tube core is in the cavity of body, it is characterized in that: be provided with passage in the tube head, an end of passage is communicated with the cavity of body, and the other end of passage is by the end and the exterior of tube head; The medial wall that is in the body at side opening rear is provided with projection and constitutes valve seat, and the front portion of tube core is provided with addendum cone and constitutes spool.
Along the direction of advance that ventricular drainage tube inserts, what arrive earlier is " preceding ", and what arrive slowly is " back ".
Be provided with projection by medial wall and constitute valve seat at the body that is in the side opening rear, the front portion of tube core is provided with addendum cone and constitutes spool, constitute a valve, in the ventricular drainage tube insertion process, spool compresses the inwall of valve seat, valve is in closed condition, stops liquid to flow in the cavity of body through side opening, reaches the purpose that prevents that liquid during insertion from spilling from the other end of body; And when ventricular drainage tube is inserted into the precalculated position, extract tube core, spool is lifted off a seat, whole drainage channel conducting, beginning draining fluids and clot; Owing to be provided with valve mechanism, tube core (comprising the forward projection of tube core) need not can prevent just that with tight contact of inwall of body liquid spills during insertion; Offer the passage of the cavity that is communicated with body in the end of tube head, make it possible to carry out drain to being in liquid and the clot that patient's ventricles of the brain go deep into the position most, drain is more thorough.
In order to reach the purpose of being convenient to determine the ventricular drainage tube insertion depth, as preferred version of the present utility model, it is characterized in that: be provided with scale on the lateral wall of described body along its length.By scale is set, can see the degree of depth that ventricular drainage tube inserts intuitively, exactly, be convenient to determine that ventricular drainage tube enters into the position of the ventricles of the brain.
In order to reach the purpose of being convenient to insert and extract tube core,, it is characterized in that: comprise that also handle, handle be located at the rear end of tube core as the further preferred version of this utility model.Hold handle, easier insertion and extract tube core.
Ventricular drainage tube of the present utility model by at the side opening rear valve being set, prevents the leak of liquid in the ventricular drainage tube insertion process, makes tube core extract easily again, by offering passage at tube head, makes drain more thorough; In addition, scale is set, is convenient to determine the insertion depth of ventricular drainage tube; Again by handle is set, more convenient insertion and extract tube core.
Description of drawings
Accompanying drawing is the structural representation of this utility model preferred implementation
The specific embodiment
Be described further below in conjunction with accompanying drawing and preferred implementation of the present utility model.
