摘要： Provided is: an access port member capable of avoiding reduction in the durability of a valve caused by welding and fixing of a body to a cap part; and a method of manufacturing the access port member. The access port member includes: a body 8 internally including a flow path 8b for circulating blood and having an opening 8c communicating with the flow path 8b; a valve 9 made of an elastic member covering the opening 8c and attached to an attachment part 8d of the body 8, the valve 9 including a slit 9a that makes a transition from a closed state to an open state when pressed by a tip 11a of a syringe 11 capable of collecting blood or injecting a drug; a cap part 10 welded and fixed to the body 8 with the valve 9 interposed therebetween and the slit 9a facing outward; and a depression 8e formed at a position between a welding part Y1 and the attachment part 8d of the body 8.

摘要： A pressure detector is provided that includes a case connectable to a flow route for liquid and attachable to a predetermined attaching surface; and a membrane member attached inside the case and with which a liquid-phase portion to be supplied with the liquid in the flow route and a gas-phase portion to be supplied with gas are separated from each other, the membrane member being displaceable in accordance with a pressure of the liquid supplied to the liquid-phase portion, the pressure detector detecting the pressure of the liquid in the flow route by detecting a pressure in the gas-phase portion. The pressure detector includes an inlet port including a connecting portion connectable to the flow route for the liquid, and a flow-route portion through which the liquid flows into an inlet opening of the liquid-phase portion; and an outlet port including a connecting portion connectable to the flow route for the liquid, and a flow-route portion through which the liquid having flowed into the liquid-phase portion is discharged from an outlet opening. The outlet opening is positioned in a part of the liquid-phase portion that includes a highest point in a vertical direction in a state where the case is attached to the predetermined attaching surface, and the outlet port extends obliquely upward from the outlet opening.

摘要： Provided is an access port member capable of facilitating connection work of a connecting member while preventing a failure in closing of a slit. The access port member comprises: a body 8 to be connected to a predetermined portion of a blood circuit for causing a patient's blood to extracorporeally circulate, the body 8 internally including a flow path 8b for circulating the blood and having an opening 8c communicating with the flow path 8b; a valve 9 that is made of an elastic member covering the opening 8c and attached to an attachment part 8d of the body 8, the valve including a slit that makes a transition from a closed state to an open state when pressed by a tip 11a of a syringe 11 (connecting member) capable of collecting blood or injecting a drug; a cap part 10 fixed to the body 8 with the valve portion 9 interposed therebetween and the slit 9a facing outward; and a rib 9b formed integrally along the periphery of the slit 9a in the valve 9.
