Accurate knowledge of the anesthetized nerve area was of great importance. In particular, in spinal anesthesia or epidural anesthesia in which a local anesthetic is injected into the subarachnoid space or epidural space, misunderstanding the anesthesia range may lead to serious life-threatening results. The nerves are anesthetized in the order of sympathetic nerve, sensory nerve, and motor nerve, but the loss of cold sensation almost coincides with the anesthesia of sympathetic nerve. You can know the area to be anesthetized. For example, if anesthesia has reached the extent of controlling the respiration and circulation, a quick lifesaving procedure should be initiated because the same innervated skin area loses cold sensation before the breathing or the heart stops. You can

ましい。In the above-described structure, the Peltier element is used as a cooling or heating means, and a cold sensation or a warm sensation is applied to the skin to be measured to examine the ability to discriminate between the cold sensation and the warm sensation. Cooling and heating of the Peltier element is rapid, the Peltier element is small and has sufficient capacity, and the Peltier element can be accurately controlled by the magnitude of the DC voltage. It can be carried out. In addition, the test can be performed simply by directly contacting the skin of the measurement site with the Peltier element, and cooling without changing the pressure and pain sensations.
It can be heated and tested. The warm / cold sensation measuring device of the present invention can determine an anesthetized nerve area by both cold sensation and warm stimulus. However, excessive warm sensation sometimes stimulates pain and may cause burns, so it is desirable to use a device mainly for cold sensation.
