Claims

[Scope of utility model registration request]

(1) A metal heat collector that can be placed opposite the blood flow path of a container that defines the blood flow path, and a metal heat collector that is electrically connected to the back surface of the heat collector that faces the blood flow path. A medical instrument comprising a thermistor, a holding part that holds a heat collector, and a connector connected to the thermistor via means for electrically connecting it.

(2) The medical device according to claim 1, wherein the area of the surface of the heat collector facing the blood flow path is at least four times the area of the joint surface of the heat collector of the thermistor.

(3) - The medical instrument according to any one of claims 1 to 2, wherein the holding portion holds a connector.

(4) The medical device according to claim 3, wherein the holding portion is made of a heat insulating material.

(5) The medical device according to any one of claims 1 to 4, wherein the holding portion is detachably attached to a container defining a blood flow path.

(6) Utility model registration claim No. 5, in which the holding part is detachable from the container by means of a lure taper.
Medical equipment as described in Section.

(7) The medical device according to claim 1 or 2, wherein the means for connecting the thermistor and the connector is a lead wire, and the diameter of the lead wire is 0.2 mm or less.

(8) The medical device according to claim 7, wherein the lead wire is coiled.

(9) The medical device according to claim 8, wherein the connector is a pin jack type connector.
