| 发明名称 | Micro-valve | ||
| 摘要 | A one-way valve (1) comprises a seat (5) and a membrane (4) having an inner portion (4a) that is stretched over the seat, wherein, in use, the inner membrane portion is selectively deflected from the seat such that a fluid path is created from one side of the membrane to the other so as to open the valve, and wherein an outer peripheral portion (4b) of the membrane is stiffer than the inner portion such that the membrane deflection is substantially restricted to only the inner portion. The one-way valve may be used in a pump for an infusion system. | ||

| 主权项 | 1. A one-way valve comprising: a seat; and a membrane having an inner portion, and an outer peripheral portion, the inner portion being stretched over the seat, and in use, selectively deflected therefrom such that a fluid path is created from one side of the membrane to the other so as to open the valve, the outer peripheral portion of the membrane being stiffer than the inner portion such that the membrane deflection is substantially restricted to only the inner portion the stiffening of the outer peripheral membrane portion relative to the inner membrane portion being effected by a rigid frame embedded in the outer peripheral portion. | ||
