Provided is an arthritis treatment method and an arthritis treatment system which can be effective for the short-term attainment of a pain relief effect. An arthritis treatment method includes an instrument introducing step of causing at least one instrument having a tubular shape to communicate with a lesion area in which crystal-induced arthritis occurs, and a treatment step of removing a causative agent of the crystal-induced arthritis from the lesion area by perfusion and discharge of a lavage fluid through the instrument.

Methods and system for treating arthritis

A shaft of a catheter is disclosed, the shaft has a thin portion, which constitutes a distal side of the shaft, a thick portion which is provided further on a proximal side than the thin portion, and a tapered portion which is provided between the thin portion and the thick portion. The tapered portion is formed more flexibly than the thick portion. The thick portion has a first thick portion and a second thick portion which is provided between the tapered portion and the first thick portion. The second thick portion has a smaller outer diameter than the outer diameter of a proximal end of the tapered portion and the outer diameter of the first thick portion, and is formed more flexibly than the first thick portion.

Catheter

A method of producing a catheter tube allows a plurality of catheter tubes to be continuously produced using a common core rod, with a proximal end connecting part efficiently attached. The method involves: forming a tubular body on the core rod including an inner layer covering body and an outer layer covering body; attaching a proximal end connecting part, forming a cylindrically shaped hub to a proximal end of the catheter tube, to a radially outer side of the inner layer covering body and the outer layer covering body; severing a tubular continuous body obtained on the core rod is severed at a given position after the proximal end connecting part is attached to produce a plurality of single tubes, each of which is provided with one of the hubs; and removing the core rod from the single tube.

Disclosed is a set for determining whether blood obtained in puncture tools by puncturing a blood vessel is venous blood or arterial blood easily, and ensuring handling under a sterile state. A set for determining blood type has a cover body to be attached to a syringe set, and a blood type determination unit to be housed in the cover body. The blood type determination unit comprises a light projecting portion and a light receiving element, and a blue output LED and a red output LED showing a judgment result based on a signal obtained from the light receiving element. The cover body has a body and a lid that are combined with each other to cover the blood type determination unit, a partition for passing blood between the light projecting portion and the light receiving element, and a pair of measurement windows for transmitting light between the light projecting portion and the light receiving element through the partition.
