Title:
医療機器用流体流量制御機構およびこれを組み込んだ保育器
Document Type and Number:
Japanese Patent JP3626809
Kind Code:
B2
Abstract:
A fluid flow controlling device having a working member capable of reciprocating in a tubular case. The working member comprises a pressure detecting portion to detect the pressure of a second fluid, which flows into the tubular case through a second inlet, and to move the working member forwards; and a valve element to decrease the opening of the first outlet in relation to the opening of the first inlet, through which the first fluid is led into the tubular case, in correspondence with the displacement of the working member. By the use of the above fluid flow controlling device, it becomes easy to control the quantity of the first fluid led into the tubular case in relation to that of the second fluid, and it becomes possible to sufficiently supplying the first fluid to the tubular case even when the second fluid is exhausted and cannot be supplied any more so long as the first fluid is not exhausted. Further, the above fluid flow controlling device has a simple structure, performs a reliable action, does not break easily, and is very durable.
