Abstract

Objects

To provide a medical device that achieves ease of operation an its operation input unit and patient'"'"'s safety simultaneously.

Mean of Achieving the Object

A medical device comprising an operation input unit 12 for an operator to enter instructions and a operation unit for performing prescribed operations required for medical treatment based on input from said operation input unit 12, consisting of a dialysis device that purifies patient'"'"'s blood by means of extracorporeal circulation, further comprising a human body detection means 18 for detecting the operator'"'"'s presence in the vicinity of operation input unit 12, and a control unit 19 that provides control for allowing input operation unit 12 to instruct the operation unit'"'"'s operations, or allowing the operation unit to operate based on the input entered into operation input unit 12, only when said human body detection means 18 is detecting the operator.

Claims

1. A medical device comprising:

an operation input unit for an operator to enter instructions; and

an operation unit for performing prescribed operations required for medical treatment based on input from said operation input unit, characterized by further comprising;

a human body detection means for detecting the operator'"'"'s presence in the vicinity of said operation input unit;

a control unit that provides control a function for allowing said input operation unit to instruct said operation unit'"'"'s operations, or allowing the operation unit to operate based on the input entered into said operation input unit, only when said human body detection means is detecting the operator.

2. A medical device as claimed in claim 1, wherein

said control function provided by said control unit can be cancelled.

3. A medial device as claimed in claim 1 or claim 2 further comprising:

a display means for displaying specific information such as operating conditions of said operation unit, wherein

said display means executes a specific display when said human body detection means detects an operator.

4. A medical device as claimed in claim 3, wherein

said display means comprises a liquid crystal display panel equipped with a backlight, and executes the specific display by lighting said backlight or raising its intensity when said human body detection means detects an operator.

5. A medical device as claimed in either one of claims 1 through 4, further comprising:

a sound output means for issuing specific sounds in accordance with operation conditions of said operation unit, and the output by said sound output means is controlled based on the detection of the presence of an operator by said human body detection means.

6. A medical device as claimed in either one of claims 1 through 5, further comprising:

an external indicator light that illuminates in accordance with operation conditions of said operation unit, wherein

the luminescence intensity of said external indicator light is made controllable based on the detection of an operator by said human body detection means.

7. A medical device as claimed in either one of claims 1 through 6, wherein

said human body detection means comprises an illumination means for irradiating an infrared light and a light receiving means for receiving its reflection, and the presence of an operator in the vicinity of said operation input unit is detected as said light receiving means receives the reflection.
