Device for generating pulsatile fluid or intermittent fluid
[Problem] To provide a device that can generate a pulsatile flow or intermittent flow from a continuously flowing fluid by pressure of the continuously flowing fluid without using an electrical activation part. [Solution] Provided is a device for generating a pulsatile fluid or intermittent fluid, comprising: an injection mechanism 110 for injecting a fluid, which is a liquid or a gas; a space cavity 120 which is a closed space the inside of which is filled with outside air; a fluid draining part 150 disposed in the lower part; and an air guide hole 141 connected to a ventilating path 140. The injection point of the injection mechanism 110 is in the vicinity of the air guide hole 141, and the injected fluid is formed such that part of the injected fluid runs downward while covering the surface of a side wall that includes the air guide hole 141 so as to limit the ventilation amount for outside air from the air guide hole 141. A strong-weak rhythm for outside air blown in arises because of variations wherein a pressure drop formed temporarily inside the space cavity 120 by the downward flowing of the injected fluid and a temporary pressure recovery by outside air being blown in from the air guide hole 141 are repeated; therefore, the fluid from the injection mechanism 110 gives rise to a pulsatile flow or intermittent flow.
