A medical connector includes: a housing comprising a male connector attachment/detachment part, the housing defining a liquid flow path; and a valve that is vertically movable with respect to the housing between a closed position for closing the male connector attachment/detachment part, and an open position in which a flow path in a male connector communicates with the liquid flow path, by the valve being pressed down from the closed position by the male connector against a biasing force. The valve comprises a head portion that closes the male connector attachment/detachment part when the valve is at the closed position, and a body portion that is connected to a bottom end of the head portion and receives the biasing force. A Young's modulus of the body portion is larger than a Young's modulus of the head portion.

Medical connector

A medical connector includes: a first connection section that defines a first passage; a second connection section that defines a second passage communicating with the first passage; and a rotation control section that controls relative rotation of the first and second connection sections. The second connection section includes a first wall face configured to abut on the first connection section to restrict the first connection section from moving in a direction to be separated from the second connection section. In a state in which the first wall face abuts on the first connection section, the rotation control section allows the second connection section to rotate relative to the first connection section in a first circumferential direction about the axis and restricts the second connection section from rotating relative to the first connection section in a second circumferential direction opposite to the first circumferential direction.

Medical devices are provided comprising a spike including proximal and distal ends, and a central axis extending from the proximal to the distal end; a valve body; a biasing body which biases the valve body; a distal tube that moves integrally with the valve body to both sides in the axial direction relative to the spike; a proximal tube fixed in the axial direction relative to the spike, the distal tube comprising a guided portion guided toward the proximal tube, and an engagement control unit which moves the guided portion toward one side in the radial direction by connection of the different medical device to the distal tube allowing the guided portion to engage with the proximal tube, and moves the guided portion toward the other side in the radial direction releasing engagement with the proximal tube when the different medical device is detached from the distal tube.

Medical device

A medical connector includes: a body member that partitions a flow path between a proximal side opening and a distal side opening; and a male connector connection portion including: a valve body facing the flow path, and a male connector connection port openable and closable by the valve body. The body member comprises a male connector housing portion configured to house a distal end portion of a male connector connected to the male connector connection portion. The male connector housing portion is configured to cause the male connector to communicate with the distal side opening and to prevent inflow of a fluid from the proximal side opening to the male connector housing portion by connection of the male connector to the male connector connection portion.

Medical connector, infusion set, and fluid collection method

An infusion set includes a first infusion line set that forms a first infusion line with an injection port; and a connector including a male connector end that is insertable into the injection port, a female connector end to which a second infusion line can be connected, a flow channel, and a partition. The injection port and the connector are configured such that, when the male connector end of the connector is inserted into the injection port, the flow channel of the connector is divided by the partition into an in-flow channel configured to let in a liquid from the injection port in the first infusion line and an out-flow channel configured to let out the liquid that has entered the in-flow channel to the injection port.

Infusion set and connector

A connector includes a housing including: an insertion section into which a male connector is insertable from an outside of the housing, and a flow path communicating with the insertion section; and an elastic valve body having a slit and configured to block the insertion section. An inner wall of the housing defining the flow path is integrally formed with a liquid barrier face. The housing is configured such that, when the male connector is inserted in the insertion section, the liquid barrier face faces a tip opening of the male connector in an insertion direction of the male connector such that liquid flowing out from the tip opening collides with the liquid barrier face.

Connector and infusion set

An ATM having a guide capability in which even a visually handicapped person who can not read braille type can positively operate a customer operating touch panel. An automatic teller machine includes a customer operating touch panel having a plurality of operating keys which are touched for actuation. Guide icons which are embossed to represent the icons of the operating keys are provided in the periphery of the customer operating touch panel at positions corresponding to said plurality of operating keys.
