Abstract: Provided is a tube set which is capable of easily determining whether a holder has been mounted when the holder is mounted on a housing. The tube set, which is provided in a tube pump that feeds a liquid, includes a pump tube and a holder. The holder has a flexible flat plate and includes first and second engagement portions located away from each other in a first direction. The first and second engagement portions are configured to be fitted into first and second engagement grooves formed in the housing, respectively, when the holder is pushed into the housing in a state of being bent in a thickness direction. The holder is elastically restored to be attached to the housing when the engagement portions are fitted into the respective engagement grooves. The holder has a flexural modulus of 500 MPa or more and 3500 MPa or less.

Abstract: The present invention provides a needle tip protector of a novel structure for an indwelling needle, which enables improvements in safety, etc. as compared with conventional needle tip protectors. A needle tip protector 10 for an indwelling needle includes a tubular peripheral wall 58, and is externally attached over a needle hub 22 of an indwelling needle 16 and moved toward a needle tip 14 side so as to cover the needle tip 14. Detents 74, 74, which are to be detained with the needle hub 22 at a position in a movement of the protector toward the needle tip 14 side of the indwelling needle 16 so as to inhibit backward movement of the protector to the proximal end side of the indwelling needle 16 and to prevent the needle tip 14 from being reexposed, are formed within an inside enclosed by the peripheral wall 58, and are integrally molded with the peripheral wall 58.

Abstract: A disposable lancing device including: a lancet housed in a housing and urged by a spring member such that a puncture member provided at a distal end of the lancet is adapted to extend out from the housing so as to carry out a puncturing operation; a locking ring disposed within the housing such that the lancet is allowed to displace in an extension direction through the locking ring; a locking protrusion provided to the lancet and adapted to be engaged by the locking ring so as to hold the lancet in a puncture-ready position located deep in the housing with the spring member being compressed; and an operating member adapted to carry out the puncturing operation by rotating the locking ring so as to disengage the locking protrusion from the locking ring and displace the lancet in the extension direction by means of the spring member.

Abstract: A bottomed, tubular hollow elastic body that opens toward an outlet side of a drug solution flow path is accommodated and arranged in an accommodation part formed in a housing, and a middle protrusion is provided protruding toward an inlet side of the drug solution flow path from a center part of a bottom wall of the hollow elastic body. Insertion of a male luer causes the bottom wall of the hollow elastic body to be elastically deformed so as to enter inside a peripheral wall, increasing the volume of the drug solution flow path, which is formed between an outer surface of the hollow elastic body and an inner surface of the accommodation part. Removing the male luer and canceling the elastic deformation of the hollow elastic body causes the volume of the drug solution flow path to be reduced.
