Abstract
The utility model relates to a medical instrument, in particular to a multifunctional external ventricle drainage device. The multifunctional external ventricle drainage device comprises an elastic silica gel catheter, and is characterized in that the front end of the silica gel catheter is in the shape of a frustum tube; at least two drainage holes are formed in the frustum tube; a developing ball is arranged at the front end of the frustum tube; a port is formed in the rear end of the silica gel catheter; one end of a flow guiding tube is connected with the port, and the other end of the flow guiding tube is connected with a metering container; a regulating and controlling valve is arranged on the flow guiding tube; and the metering container is connected with a negative pressure device. By the multifunctional external ventricle drainage device, a drainage tube can be smoothly inserted in the ventricle of a patient, brain tissues are effectively protected against being injured, the drainage tube can be placed at an accurate position by the developing ball, and the safety of the patient is guaranteed to a maximum degree; a plurality of drainage holes are adopted and are not easy to block, the pressure of the ventricle can be regulated by the regulating and controlling valve, and the metering container can accurately meter drainage volume and can realize active drainage; and the multifunctional external ventricle drainage device has the advantages of novel design, convenience in operation, safety in use, good drainage effect and the like, and is particularly applicable to external ventricle minimally invasive drainage surgeries.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of simple in structure, multiple functional, EVD device that result of use is good.
Background technology
As everyone knows, the EVD device that uses clinically now is made up of monolayer drainage tube and syringe, and the employed material of drainage tube is a silica gel catheter; It is planar that the front end of silica gel catheter is sharp bevel, has conduction hole on the inclined-plane, and the rear end of silica gel catheter is provided with the plug socket that is connected with syringe adapter; The deficiency of this silica gel catheter is function singleness, complicated operation, can not keep somewhere, repeatedly puncture etc., causes the conduction hole on the inclined-plane to stop up during use easily, makes drainage of cerebrospinal fluid not smooth; Silica gel catheter is the blood vessel that sharp-pointed head is prone to stab the patient; Owing to do not have X line development labelling on the silica gel catheter, be not suitable for modern Minimally Invasive Surgery operation, in addition; There are not anti-reflux and the device of regulating cerebral, control drain on the outer silica gel catheter of the existing ventricles of the brain; In clinical use, can cause drainage of cerebrospinal fluid deficiency or drain excessive like this, thereby cause severe complications, even threat to life.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, provide a kind of easy to operate, keep somewhere convenient, conduction hole and be difficult for stopping up, being suitable for the multi-functional EVD device that Minimally Invasive Surgery uses.
This utility model can reach through following measure:
A kind of multi-functional EVD device includes elastic silica gel catheter, it is characterized in that the silica gel catheter leading section is the frustum tubulose; At least be provided with two conduction holes on the frustum pipe, frustum pipe front end is provided with the development ball, and the silica gel catheter rear end is provided with connector; Mozzle one end is connected with connector; The other end of mozzle is connected with the container of band metering, and mozzle is provided with controlling valve, and the container of band metering is connected with negtive-pressure implement.
This utility model guarantees that drainage tube successfully inserts, and has protected cerebral tissue injury-free effectively, and the position that the development ball can make drainage tube place is more accurate; At utmost guarantee patient's safety, be provided with a plurality of conduction holes, conduction hole is difficult for stopping up; Controlling valve can be regulated ventricles of the brain pressure; The container of band metering can accurately measure drainage flow and initiatively drain, has modern design, easy to operate, safe in utilization, advantage such as drainage effect is good, is specially adapted to Wicresoft's surgical drainage outside the ventricles of the brain.
Description of drawings
Fig. 1 is a kind of structural representation of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
Shown in accompanying drawing, a kind of multi-functional EVD device includes elastic silica gel catheter 1; Silica gel catheter 1 leading section is the frustum tubulose, is provided with two conduction holes on the frustum pipe 2 at least, and frustum pipe 2 front ends are provided with development ball 3; Silica gel catheter 1 rear end is provided with connector, and mozzle 4 one ends are connected with connector, and the other end of mozzle 4 is connected with the container 5 of band metering; Mozzle 4 is provided with controlling valve 6, and the container 5 of band metering is connected with negtive-pressure implement 7, and container 5, controlling valve 6 and the negtive-pressure implement 7 of silica gel catheter 1, development ball 3, mozzle 4, band metering are identical with prior art; This does not give unnecessary details, and this utility model guarantees that drainage tube successfully inserts, and has protected cerebral tissue injury-free effectively; The position that the development ball can make drainage tube place is more accurate, at utmost guarantees patient's safety, is provided with a plurality of conduction holes; Conduction hole is difficult for stopping up, and controlling valve can be regulated ventricles of the brain pressure, and the container of band metering can accurately measure drainage flow and initiatively drain; Have advantages such as novel in design, easy to operate, safe in utilization, that drainage effect is good, be specially adapted to the outer Wicresoft of ventricles of the brain surgical drainage.
