2. Description of the Related Art In recent years, various living body information collecting devices, living body monitoring devices, and the like have also been digitized, and accordingly, the mounting density has increased.
The amount of heat generated by the device is also increasing. For this reason, there is a possibility that the internal temperature of the apparatus rises to cause a failure or malfunction of the machine. In order to prevent such a situation, it was necessary to perform some kind of device cooling.

For this reason, computer-related equipment and general personal use electronic equipment have been cooled by installing a cooling fan and forcibly taking in external air into the apparatus.

[0004]

However, when the apparatus is a biological information processing apparatus such as a patient monitoring apparatus, it is often used in an operating room or an intensive care unit, and dislikes dusting. In addition, they dislike agitation of gas that is heavier than air, such as anesthetic gas, and are also required to be quiet. For this reason, the cooling fan is often too loud to be used. For this reason, it is conceivable to provide a large number of large holes in the housing of the device in order to cause convection of air in the device. However, when using various medicines around the device or when the patient using the device is living in bed, it may accidentally spill liquids (water, various drinks, drugs, etc.) In such a case, there is a possibility that the liquid may enter the device through the hole and cause a malfunction of the device.
