The utility model comprises an upstream drainage tube (1), a downlink drainage tube (2), a pressure regulating tube (3) and a calibration board (4), which has the functions of preventing excessive external ventricular drainage and avoiding siphonage effect, and has the characteristics of monitoring and controlling the intracranial pressure during the process of drainage and being convenient for the patient to move.
Description
Technical field
This utility model relates to Medical Instruments, particularly the ventricular drainage device.
Background technology
EVD is a neurosurgery therapeutic modality commonly used, is mainly used in drain blood and cerebrospinal fluid behind the disease surgeries such as intraventricular hemorrhage, hydrocephalus, intraventricular tumor, indoor vascular malformation, to reduce or the control intracranial pressure.At present, common practice at ventricular drainage is both at home and abroad, ventricular drainage tube is directly inserted drainage bag or drainage bottle, the maximum deficiency of this kind method is that part is to cause drain excessive easily, cause ventricular hemorrhage, also there is siphonage even raise drainage tube, causes drain excessive equally, cause adverse consequences.In addition, the shortcoming of this method also be included in cause easily in the carrying patient process external drainage excessively and patient's bed activities limited.
Summary of the invention
Task of the present utility model provides a kind of EVD pressure control monitor, make it have the function that can prevent effectively that EVD is excessive and avoid siphonage, also have simultaneously in drain and can observe and control intracranial pressure, and be convenient to characteristics such as patient activity, to overcome the deficiency of existing direct drainage.
The EVD pressure control monitor that this utility model provides comprises the up drainage tube 1 that is connected with ventricular drainage tube, the descending drainage tube 2 that is connected with drainage bag or drainage bottle, the adjusting of the pressure between the former two tube 3 and graduated tile 4; It is the hollow columnar cavity that pressure is regulated tube 3, and the upper shed 5 that communicates with atmosphere is arranged at its top, and its bottom has two openings to be connected with up drainage tube 1 and descending drainage tube 2 respectively; Graduated tile 4 is rectangular plate-like structure, and its front indicates scale, its back side have in order to this graduated tile 4 is hung be fixed on the wall or the sick bed bedstead on and can regulate the suspension of this graduated tile 4 or the adjustable fixture 6 of level altitude; Pressure is regulated tube 3 and is hung on the positive corresponding scale position of this graduated tile 4 by actual needs by adjustable hanging connecting device 7.Adjustable hanging connecting device 7 can be made up of aperture 8 that is positioned at the vertical arrangement on the graduated tile 4 and the hook 9 that is positioned on pressure adjusting tube 3 cylindrical shells; Also can form by the magnetic material that participates in constituting the ferrous material of graduated tile 4 and be positioned on pressure adjusting tube 3 cylindrical shells.Adjustable fixture 6 can place the forked card 12 of steel elasticity of chute 10 to form by adjustable screw 11 by vertical chute 10 and its root of being arranged in graduated tile 4 back sides; Also can place the hook of chute 10 to form by adjustable screw 11 by vertical chute 10 and its root of being arranged in graduated tile 4 back sides.
During use, up drainage tube 1 is connected with the EVD pipe, descending drainage tube 2 is connected with drainage bag 14 or drainage bottle, graduated tile 4 hung by adjustable fixture 6 or be fixed on the wall or the sick bed bedstead on, insert on the graduated tile 4 and the corresponding aperture of intracranial pressure scale 8 positions of presetting with regulating tube 3 by linking up with 9, in case surpassing, the drain liquid level presets the intracranial pressure scale, cerebrospinal fluid can overflow from the mouth of pipe of regulating tube 3 that is positioned at of up drainage tube 1, and in descending drainage tube 2 inflow drainage bags 14 or drainage bottle, below the intracranial pressure scale that intracranial pressure is controlled at all the time preset, thereby realized in EVD, can presetting, the purpose of observation and control intracranial pressure, simultaneously, owing to be positioned at adjusting tube 3 tops upper shed 5 is arranged, make the pressure of regulating in the tube 3 identical with atmospheric pressure, eliminate siphonage, thereby overcome the deficiency that the direct drain of traditional single tube causes excessive drain easily.Because device has hand propelled compressing switch 13 on up drainage tube 1, so, move patient and patient when movable in bed at needs, can close this compressing switch earlier, thereby eliminate because of move patient and patient in bed activity to the harmful effect of drain generation.
