FIELD: medical equipment. ^ SUBSTANCE: valve has the basis without carving, a demountable insert without carving and the return valve located in an insert aperture. The part of the return valve has an elastic leg for support in the inspissation established in the insert. There are versions of performance of the valve unit. In one version the pair of elastically spring-applied latched levers keeps the insert in the basis. Flanges on latched levers are elastically spring-applied for bending and basis capture at insert pushing in the basis. Insert extraction is carried out by means of remission and lifting of latched levers. In other version the insert is magnetically bridged to the basis. The elastically spring-applied part of the return valve and a regulator in the form of a set screw regulate pressure of the stream. ^ EFFECT: improvement of prosthesis operation conditions. ^ 21 cl, 6 dwg |
