The present disclosure relates to a continuous positive airway pressure (CPAP) device which sends, into an airway of a user, air sucked into the device. A body unit as a first unit has a cylindrical first lead-out portion through which air circulates. A base unit as a second unit has a third introduction portion to which the first lead-out portion is to be connected. A body-side terminal is provided as a first terminal with conductivity at the first lead-out portion of the body unit. A base-side terminal is provided as a second terminal with conductivity at the third introduction portion of the base unit. The body-side terminal is in contact with the base-side terminal while the body unit is attached to the base unit.

CPAP device

The respiratory blowing device is provided with a first unit including a first housing and a second unit including a rotating body and a second housing. The first housing includes a first outlet, the rotating body includes a first coupling port and a first coupling path, and the second housing includes a first inlet and a second outlet. The rotating body is configured to rotate between a first position and a second position. At the first position, the first outlet is coupled to the first coupling port in a state that the first housing and the second housing are separated from each other. At the second position, the first housing is attached to the second housing by the rotation of the first housing to approach the second housing in a state that the first outlet is coupled to the first coupling port.

Respiratory blowing device

A fluid control device includes a tube insertion portion formed in a casing, a fixing member that fixedly holds, in the tube insertion portion, a tube inserted into the tube insertion portion, a pressing member driven by an actuator to press the tube within the tube insertion portion, and a controller that controls the actuator for the pressing member, wherein the controller controls the pressing member to start pressing on the tube after the fixing member has fixedly hold the tube in the tube insertion portion.

Fluid control device

A dropping rate measuring device for measuring a flow rate of liquid droplets which grow on a lower end of a nozzle and intermittently drop from the lower end of the nozzle includes an imaging unit that images a growing liquid droplet which is growing on the lower end of the nozzle at a plurality of time points and acquires a plurality of pieces of image data of the growing liquid droplet, and a data processor that calculates the flow rate by analyzing the plurality of pieces of image data acquired by the imaging unit.

A step board is attached to a main body in a rotatable manner. The step board is biased toward the upper side due to a tensile force of a spring while taking a position at which the step board is attached to the main body as an axis, and an attachment angle thereof is so fixed by a stopper as to fall within a predetermined angle. On the lower side of the step board, a cylinder unit covering a side surface of the bar-like main body is provided. The cylinder unit is connected to a brake shoe. Accordingly, when the step board is stepped on, the cylinder unit is moved downward so that the brake shoe makes contact with part of a rear wheel, thereby limiting a rotational velocity of the rear wheel.

Pushcart

A support unit is connected to a shaft of a main wheel and thus is always maintained in parallel to or at a predetermined angle to a road surface, independently of an inclination angle of a main body. Accordingly, an incline estimating unit regards an inclination anglebeing a value in an inclination sensor as being equal to an inclination angleof the road surface (or in a case where the support unit is inclined a predetermined angle to the road surface, an angle from &#x3b8;to the predetermined angle is subtracted from or added to the crossing angle) and outputs the estimated inclination angleof the road surface to a target inclination angle determining unit.

Hand-propelled vehicle

A pushcart according to the present disclosure provides a warning on the basis of a first weight at a position outside a region between a shaft of front wheels and a shaft of rear wheels when viewed from the vertical direction and a predetermined weight. For example, the predetermined weight is the weight on a mounting portion located between the shaft of the front wheels and the shaft of the rear wheels when viewed from the vertical direction. When the first weight is larger than the predetermined weight, an informing unit can provide a warning by using a sound, light, and the like and enable a user to recognize that there is a possibility that the pushcart will turn over.

A handcart includes a main body, main wheels, support portions, auxiliary wheels, an extended portion, connection portions, a tilt angle sensor, and a gyro sensor. The main body is supported at one end thereof to be rotatable in a pitch direction relative to a pair of the main wheels. A bar-shaped connection portion of the extended portion is inserted through a tube portion at another end of the main body. The extended portion extends from the other end of the main body to a rear side in a travelling direction of the handcart. A region of each support portion from a rotation shaft of the main wheel to a rotation shaft of the auxiliary wheel and the extended portion are connected to each other by the connection portion. The connection portion is supported to be rotatable in the pitch direction relative to the support portion and the extended portion.

Handcart

A pushcart includes a main body, a pair of main wheels, a supporter, an auxiliary wheel, a blocking unit, a switching lever, a slope angle sensor, a gyrosensor, a driver unit, and a supporter rotary encoder. The supporter rotary encoder detects an intersecting angle which is an angle formed by the main body and the supporter, and outputs the detected result to a controller. The gyrosensor detects an angular velocity of the main body in a pitch direction and outputs the detected result to the controller. The controller performs inverted pendulum control in a first control mode based on the detected results of the gyrosensor and the supporter rotary encoder. The controller performs inverted pendulum control in a second control mode based on the detected result of the gyrosensor.
