Benefits of technology

[0013]An object of the present application is to take account of the clinical situations and to minimize stress to the patient.SUMMARY

Problems solved by technology

An uncontrolled discharge is just as dangerous as an excessive pressure.
External drainages have a rapidly increasing risk of infection as a function of the duration of the treatment.
In view of the extremely high risk of infection, an external drainage can no longer be justified after seven to ten days.
Internal drainage by means of a shunt system has a high risk of blockage by blood components in the cerebrospinal fluid.
Considering the low pressures that are encountered with a limited clearance between the rotary slider and the inner side of the housing, a gasket is unnecessary and / or not desired.
A self-activating brake may then be unnecessary and are not desired.

Embodiment Construction

[0078]In the drawing of FIG. 1 an embodiment of the present application is illustrated in the switch position 1 (discharge 1 closed, discharge 2 open).

[0079]In the drawing of FIG. 2 is illustrated the view of the section A-B of the switch of FIG. 1.

[0080]The two-way discharge switch comprises a solid metallic housing 1-1, a lid 1-2, a base 2-2 as well as an inlet port 1-2 and outlet port 1-3. Moreover, in the embodiment, the 2-way discharge switch possesses a closing element 1-4 / 2-3 that is mounted on the shaft 1-5 / 2-4, a spring system 1-6 / 2-5 with a ball 1-7 / 2-6 for the precision non-return valve and a locking device 2-7. The two-way discharge switch is located in a tube that is implanted in a patient for cerebrospinal fluid drainage. The two-way discharge switch has three switching states. Switching state 1 closes discharge 1 and opens discharge 2, switching state 2 closes both discharges 1 and 2, and switching state 3 closes discharge 2 and opens discharge 1. In the switching sta...
