Abstract
The invention discloses an analgesia control device which comprises an analgesia infusion pump, a medicine feeding device, a respiratory monitor and an infusion pipeline. Analgesia medicines are currently infused by the aid of an analgesia pump, so that pain of a cancer patient and a postoperative patient is relieved, serious adverse effects such as respiratory depression and reduction of blood oxygen saturation are generated, and a control device for analgesia is absent. In order to overcome the shortcomings of the prior art, the technical scheme includes that the pain can be effectively controlled by the aid of a constant-speed micro-infusion analgesia pump, and a respiratory state can be dynamically displayed by the aid of the respiratory monitor. When respiratory frequency is smaller than or equal to 8 times per minute and the blood oxygen saturation is reduced, a photoelectric blood oxygen saturation sensor is connected with a receiving processing circuit, an alarm circuit and a changeover switch in the monitor and linked with an electromagnetic valve, and automatic alarm and self-closing infusion safety control is realized. The analgesia control device is applicable to clinical application of cancer patients and postoperative pain patients.
