Abstract: A medical fluid injection device includes a pump, a communication part, a pump control part, and a storage part. The pump control part is configured to control the pump to start a medical fluid injection when the communication part receives a start signal, and stop the medical fluid injection when the communication part receives a stop signal. The storage part is configured to store start inputter information together with start instruction information indicating that an instruction to start the medical fluid injection is given, and stop inputter information together with stop instruction information indicating that an instruction to stop the medical fluid injection is given.

Abstract: A waste liquid receptacle includes first and second cover members for covering first and second openings, respectively. The first cover member is made of a material that is configured to: (i) be plastically deformed upward by a first suction force in a state where a second negative pressure is generated in an upper space; and (ii) plastically deform downward by a depressing force against the first cover member downward in a state where an openable and closable lid is open and the second negative pressure is released. The second cover member is made of a material that is configured: (i) not to be plastically deformed by a second suction force in a state where a first negative pressure is generated in a waste liquid receipt space; and (ii) to be broken without being plastically deformed when a depressing force is applied to the first cover member.

Abstract: A negative pressure is generated in an upper space of a canister due to a suction force of a suction source and, then, a negative pressure is generated in a waste liquid receiving space of a cylindrical body in response to the generation of the negative pressure in the upper space . At this stage of the operation, a first covering member that covers a first opening that opens facing the upper space in a waste liquid treating agent storing portion plastically deforms upward by a suction force caused by a negative pressure in the upper space. On the other hand, when a depressing force that pushes the first covering member downward is applied to the first covering member in a state where an opening and closing lid of the canister is opened so that a negative pressure in the upper space is released, the depressing force is transmitted to a second covering member so that the second covering member is broken.

Abstract: One aspect of the present invention relates to a waste liquid treatment composition for treating a waste liquid containing a body fluid to separate the waste liquid into a supernatant and an aggregate in a container. The waste liquid treatment composition comprises: a solid flocculant having at least one group selected from the group consisting of an OH group, an NH group, and an FH group; and a solid compound having at least one group selected from the group consisting of an OH group, an NH group, and an FH group.

Abstract: A tracheal tube inserted through the trachea and bronchi of a subject, comprising: a tube body having a through hole on an outer circumferential surface thereof, a bronchial cuff provided on an outer circumferential surface of the tube body and pressing an inner circumferential surface of the bronchus; wherein the bronchial cuff is spaced apart in the axial direction of the tube body and forms a plurality of ventilation spaces; wherein the ventilation spaces are in communication with each other; wherein the through hole communicate with the ventilation space.

The pump control part is configured to control the pump to start medical fluid injection when the communication part receives a start signal, and to stop the medical fluid injection when the communication part receives a stop signal, and the storage part is configured to store start inputter information together with start instruction information including information indicating that an instruction of starting the medical fluid injection is given, and stop inputter information together with stop instruction information including information indicating that an instruction of stopping the medical fluid injection is given.

Abstract: The ease and rapidity of testing using magnetic particles can be improved. Included is an action step of causing a magnetic collector with recovered magnetic particles adhering thereto to contact a liquid that acts on a target component, and causing the liquid to act on the target component in a state in which the magnetic particles are adhering to the magnetic collector.

Abstract: The pump unit comprises a pump including a piezoelectric element and a discharge mechanism for discharging fluid according to operation of the piezoelectric element, and a valve mechanism attached to the pump. The discharge mechanism and the valve mechanism are separately formed by joining a plurality of metal layer pieces stacked in a predetermined stacking direction by diffusion welding, and are secured to each other by diffusion welding.

Abstract: A storage container includes a storing section including a storage space and an inflow port, and a water sealing section. The storing section includes an inflow section connectable to a tube and a volume changing section capable of changing the volume of the storage space. The volume changing section is deformed to increase the volume of the storage space when pressure in the storage space is about to rise to be equal to or higher than a reference pressure set in advance and is deformed to reduce the volume of the storage space when the pressure in the storage space is about to drop to be lower than the reference pressure.

Abstract: Provided is a novel method for designing a mutant primer in which a nonspecific amplification caused by a primer dimer or loop structure scarcely occurs.

Abstract: A cuff-equipped tube formed by providing a cuff to the outer periphery of a flexible tube, the cuff being expanded by introducing an operation fluid thereinto or being contracted by discharging the operation fluid therefrom. The cuff is provided with a cuff affixing portion expanded outward by the introduction of the operation fluid thereinto, and also with one mounting portion and the other mounting portion that are mounted to the outer peripheral surface of the tube. The connecting portions of the cuff affixing portion and the one mounting portion is affixed in a constricted shape to the outer peripheral surface of the tube, and the connecting portions of the cuff affixing portion and the other mounting portion is affixed in a constricted shape to the outer peripheral surface of the tube.
