Abstract
The utility model relates to a brain puncturing drainage device, belonging to the field of medical appliances, which is mainly composed of a drainage tube 1, a hollow joint 5, a guide needle 2, a needle handle 6, a three-way valve 3, a stopper 4 and a valve core 7. When used, the drainage device can make the puncture and the insertion of the drainage tube accomplished once; when medicine injection is needed, the disassembly and assembly of a drainage bag can be avoided, and the infection of intracalvarium is reduced. The utility model is an ideal medical appliance.
Description
This utility model relates to a kind of brain puncturing drainer, and it is a kind of being applicable to cephalophyma orientation puncture, extracts hematocele out or inject the medical apparatus of medicine in brain, belongs to medical instruments field.
At present, carry out the hollow metal brain pin that the brain puncture drainage adopts the band nook closing member clinically,,, extract then, flexible pipe one end is sent into along the duct to the puncture of cephalophyma position by sphenotresia.During drain, the flexible pipe other end connects drainage bag; During injection, pull up drainage bag again.This utensil and method make and insert drainage tube and can not once finish, need be when the intracranial injection, and the repeated disassembled and assembled drainage bag makes intracranial very easily infected again.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and makes puncture, inserts drainage tube and once finish; When needing injection, can avoid the dismounting drainage bag, reduce the infected novel drainage device of intracranial.
In order to achieve the above object, this utility model by the following technical solutions, it mainly is made up of drainage tube 1, guide pin 2, three-way valve 3, stopper 4, hollow joint 5, needle handle 6 and three-way valve core 7.
Now in conjunction with the accompanying drawings this utility model is illustrated.
Fig. 1 is the structural representation of drainage device.
Fig. 2 is the positive cut-away view that guide pin inserts drainage tube.
As shown in Figure 1: drainage tube 1 is a kind of translucent flexible pipe, and head is pure circular cecum, and sidepiece has the hole, and the thickness of pipe and length, side opening quantity and size can depend on the needs; The other end of flexible pipe is openend, and opening part is equipped with hollow connector 5, hollow connector in addition One end can be pegged graft to 3.1 with one of triple valve 3, and another of valve is furnished with in a stopper 4. triple valves to 3.2 a spool 7 is arranged, and it can rotate in valve.
As shown in Figure 2: during puncture, is furnished with guide pin 2 in the drainage tube 1, the external diameter of guide pin is less than the internal diameter of drainage tube, its end is the cecum bottom that pure circular needle point reaches drainage tube 1 just, the guide pin other end and needle handle 6 are connected as a single entity, and needle handle just in time clogs hollow connector 5, and needle handle external diameter and hollow connector internal diameter are tight fit, needle handle vertically have a hole, guide pin is rigid body.
Embodiment: get internal diameter 3mm, long 165mm silica gel urinary catheter leading portion is done drainage tube, get 3 elliptical apertures (3mm * 2mm) at its cecum sidepiece, make guide pin with the long 180mm stainless steel silk of diameter 1.5mm, the guide pin tip is pure circle, the other end is connected to the long needle handle of 16mm, and the total length that needle handle and guide pin fuse makes in the drainage tube of guide pin insertion with hollow joint just, and the guide pin tip reaches drainage tube cecum bottom, needle handle external diameter and hollow joint internal diameter tight fit, needle handle vertically has the ventilating slit.
According to the CT image, will insert sphenotresia during use, and when in seeing drainage tube, hematocele being arranged, prove and puncture successfully, extract guide pin then through the drainage tube of aseptic sterilization band guide pin; Anti-three-way valve one is received the drainage tube opening to 3.1, and the three-way valve other end 3.3 connects drainage bag, simultaneously with another of stopper jam-pack valve to 3.2.The swivel tee spool is connected drainage tube and drainage bag, can carry out drain; During injection, the swivel tee spool makes drainage tube communicate with 3.2 1 ends of valve, and this moment, valve core disconnected drainage tube and drainage bag, pulled up stopper, got final product injection.This structure can the dismounting drainage bag, and injection and drain are hocketed.
