Description of drawings
Fig. 1 looks sketch map for master of the present utility model;
Fig. 2 is the partial enlarged drawing that traveller is installed in the connection tube among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, under the dura mater of craniocerebral operations hindbrain or pipe outlet 2 places, outer end of the external drainage flexible pipe 1 that inserts of Intraventricular, be connected with fluid pressure table 5 with connection tube 4.
The left tube head of connection tube 4 and drain flexible pipe 1 are communicated with, and the right-hand member of connection tube 4 is communicated with the joint 8 of Pressure gauge 5.Like this, be in the complete closed state between cranium brain and the Pressure gauge 5, the cerebrospinal fluid of drawing can directly demonstrate accurate data on Pressure gauge 5, can observe patient's intracranial pressure situation of change at any time accurately, safely, so that formulate suitable therapeutic scheme.
If directly be connected pressure measurement with Pressure gauge 5 with the pipe outlet 2 of drain flexible pipe 1, Pressure gauge 5 can only be disposable use, perhaps will carry out thorough disinfection to Pressure gauge 5 before repeated use, to avoid the cross infection between the patient.Because fluid pressure 5 tables belong to precision instrument, sterilization is the thing that bothers very much after each the use, and does not do a good job and also can destroy the precision of instrument; If Pressure gauge as disposable use, will be caused certain waste, the operation cost is too big;
At the stage casing of connection tube 4 inner chamber a traveller 4.1 (referring to Fig. 2) is installed, traveller 4.1 can be under fluid pressure promotes, movable in cylinder as piston, move left and right in connection tube 4 inner chambers, and the inner chamber of connection tube 4 is divided into left chamber 4.2 and right chamber 4.3, the cerebrospinal fluid 4.4 that traveller 4.1 will be drawn from drain flexible pipe 1 intercepts in left chamber 4.2, and can not flow to right chamber 4.3, thereby has avoided pathogenic bacteria in the cerebrospinal fluid 4.4 to the pollution of Pressure gauge 5; Under cerebrospinal fluid 4.4 thrusts of drawing, traveller 4.1 is the medium 4.5 by filling in the right chamber 4.3 again, transfers the pressure to Pressure gauge 5 simultaneously, and data presented is exactly the exact value of patient's intracranial pressure on the Pressure gauge 5.The media 4.5 of turning right and filling in the chamber 4.3 can be gas, but preferably with the little liquid filling of compressibility, medium 4.5 can inject in the right chamber 4.3 with needle tubing.
