摘要： A measurement probe includes: an elongated body that is insertable into a catheter having a flow path; a sensor fixed to the elongated body and capable of detecting a state of a fluid flowing in the flow path; and a sensor holding portion that holds the sensor at a predetermined position when the elongated body is inserted into the catheter. An output of the sensor changes depending on an oxygen partial pressure in the fluid, a carbon dioxide partial pressure in the fluid, a hydrogen ion index of the fluid, an amount of potassium ions in the fluid, an amount of sodium ions in the fluid, an amount of chlorine ions in the fluid, a temperature of the fluid, or a flow rate of the fluid.

摘要： A measurement device that allows a user to easily change a time axis of a graph indicating parameters measured using a bladder indwelling catheter. The measurement device includes a measurement unit that sequentially measures parameters related to urine on the basis of information obtained by a sensor disposed so as to be contactable with urine to be conducted by a catheter, a display unit that displays the parameters as a graph using a time axis, and a reception unit that receives a change instruction related to the time axis.

摘要： A drug supply device for supplying drug to a living body surface that includes a shaft and a drug holding sheet attached to the distal end of the shaft. The drug holding sheet has a first face that faces distally and a second face opposite the first face that faces proximally when the drug holding sheet is expanded. The drug holding sheet includes folded portions that fold such that the first face is positioned to face radially inward while exposing the second face to an outside environment when the drug holding sheet is in a folded state. A drug is applied on the first face of the drug holding sheet. The drug supply device includes an expandable member on the second face of the drug holding sheet. The expandable member is expandable to cause the drug holding sheet to expand from the folded state into the expanded state.

摘要： To provide a prediction display system and the like that utilize information obtained before an operation and during the operation, and predict an onset risk of a postoperative complication such as an acute kidney injury which has become a particularly great clinical problem. A prediction display system is configured such that an onset risk of a complication occurring after an operation is predicted using at least one of pH (hydrogen ion exponent), pO2 (oxygen partial pressure), Ht (hematocrit value), Hb (hemoglobin), DO2 (transportation amount of oxygen), and pCO2 (arterial blood carbon dioxide partial pressure) as parameters of blood gas taken before the operation and during the operation, and the onset risk of the complication occurring after the operation is displayed.

摘要： A medical apparatus for joining body lumens in a living body includes a puncture member having a lumen, a distal opening portion and a needle tip at the distal end of the lumen. The needle tip can puncture a tube wall of the body lumen to form a puncture site. The medical apparatus includes a tubular member in the lumen of the puncture member that expands radially outward and contracts radially inward and a plunger movable relative to the puncture member to release the tubular member from the distal opening portion of the puncture member. The tubular member expands to be fixed to the puncture site when the tubular member is released from the distal opening portion of the puncture member.
