Title: Respiration assisting lung system
Inventor: NINOMIYA JUNICHI
IPC: A61M1/14
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a convenient respiration assisting lung system which gives a little load to a patient with respiratory insufficiency and assists the lung function of the patient. SOLUTION: In this respiration assisting lung system, blood in an artery is made to flow separately into a blood removing tube 18 by connecting an artery connecting part 16 with an artery 12 of a patient A through this artery connecting part 16. The blood of the artery from this blood removing tube 18 is sent from an inlet 26 of an artificial lung 24, where carbon dioxide in the blood of the artery is replaced with oxygen to elevate oxygen partial pressure. The blood having been already gas-replaced and with a high oxygen partial pressure is sent out into a blood transferring tube 38 from an outlet 36 of the artificial lung 24 and this blood is sent into the vein through a vein connecting part 42.  As the starting point is an artery 12 with a high blood pressure and the end point is a vein 14 with a low blood pressure in this extracorporeal circulation passage, a flow is formed from the artery 12 being the starting point to the vein being the end point caused by pressure difference between the starting point and the end point. It is possible therefore to provide a convenient respiration assisting lung system wherein it is unnecessary to provide a blood pump, or the like, like the conventional V-A bypass.

Abstract: PURPOSE:To obtain a low-cost and simple-constitution AGC circuit which can be formed suitably into an AC circuit by securing an effective application of AGC to the 1st step of the intermediate frequency amplification step and the frequency conversion step based on the detection output in accordance with the input and the output. CONSTITUTION:With increment of the reception input signal, the detection output is obtained at the output of AM detection circuit V in accordance with the input signal. As a result, the base bias becomes shallow for transistor TrQ36 of AGC amplifier VI, and the current decided by resistance R29 flows to TrQ37 with generation of the voltage across resistance R30. And the AC component is eliminated by capacitor C4. By the DC voltage, the current flows to TrQ23 to decrease the gain of TrQ24 and then to lower the gain of the differential amplifier consisting of TrQ25 and Q26 of intermediate frequency amplifier circuit IV. While the collector current TrQ23 is led to the current Miller comprising TrQ21 and Q22, and the current equal to the level of the collector current is led to resistance R2 to give bias to the base of TrQ6. As a result, the amplification factor is lowered for frequency converter circuit I.
