摘要： An oxygen measurement device constituting an oxygen measurement system includes a urethral catheter and an oxygen sensor main body. The urethral catheter has a shaft in which a urethral catheter lumen that enables circulation of urine flowed in via a urethral catheter port from inside a bladder is formed; and has a hub in which a urine lumen that is provided at a proximal end of the shaft and communicates with the urethral catheter lumen is formed. The oxygen sensor main body is provided on the hub in a manner capable of being brought into contact with urine circulating in the urine lumen, and detects oxygen in the urine.

摘要： Provided is a medical device capable of easily changing a position of the device inside a biological lumen and effectively removing a cut object. The medical device for removing the object in the biological lumen has a drive shaft, a cutting portion, a first housing that accommodates the drive shaft to be rotatable, a second housing that is rotatable with respect to the first housing, and a support portion that supports the first housing and the second housing. The second housing and the support portion relatively move along an axis to restrict relative rotation of the first housing and the second housing. The support portion supports the second housing to be rotatable around the axis, and restricts a relative movement and a relative inclination of the second housing and the support portion in a direction intersecting with the axis.

摘要： A device for stably maintaining the shape of a fragile object in a liquid includes a container for accommodating the fragile object, a lid member for sealing the container, and a protecting member. The device is configured to form a liquid-tight space by covering a liquid surface in the container which accommodates the fragile object and the liquid with the protecting member and further covering the protecting member and an open portion of the container with the lid member.

摘要： The syringe includes first and second outer cylinders having a flowing port at a distal end through which liquid is flowable, and a plunger inserted from the proximal side of the outer cylinder. The syringe includes a tooth portion provided along the direction of movement of the plunger, and a hook configured to lock the tooth portion at a predetermined locking position and prevent the movement of the plunger in the direction toward the proximal end. The hook retracts from the locking position in association with the unlocking operation and restores automatically to the locking position after the unlocking operation.

摘要： A medical device for removing an object in a body lumen includes a catheter and a drive device. The drive device includes a hub support portion with which a hub portion of the catheter is interlocked. The hub portion has first and second engagement portions interlocked with the hub support portion. The hub support portion includes a rotation blocking portion that is engaged with the first engagement portion to block the hub portion from rotating with respect to the hub support portion, a movement blocking portion that is engaged with the second engagement portion to block movement of the hub portion with respect to the hub support portion in an axial direction, and a releasing portion that releases a state in which a rotation of the hub portion is blocked while maintaining a state in which movement of the hub portion is blocked.
