pain control device

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.

Description

Technical field [0001] The invention relates to an analgesic control device. Background technique [0002] Pain is one of the most common symptoms of cancer and postoperative patients. It seriously affects the quality of life of the patient. If it is not relieved, the patient will feel extremely unwell, which may cause or aggravate the patient’s anxiety, depression, fatigue, insomnia, and loss of appetite. For other symptoms, the treatment of pain includes: cause treatment, drug analgesia and non-drug treatment. At present, analgesic pump is an effective tool to control pain. It enables analgesic drugs (mainly opioids) to maintain a stable concentration in the plasma, and allows patients to self-press the drug to enhance the analgesic effect, but analgesia is used The serious side effect of pump infusion of analgesics is respiratory depression. The clinical manifestations are respiratory rate ≤ 8 times / min and decreased blood oxygen saturation. However, the current analgesic pum...

AI Technical Summary

Problems solved by technology

At present, the analgesic pump is an effective tool for pain control. It can maintain a stable concentration of analgesic drugs (mainly referring to opioids) in the blood plasma, and allow patients to press and administer the drugs themselves to enhance the analgesic effect. Pump infusion of analgesic drugs, its serious side effect is respiratory depression, clinical manifestations are respiratory rate ≤ 8 times / min, blood oxygen saturation decreased, but the current analgesic pump does not have the function of monitoring the patient's respiratory rate and blood oxygen saturation , so design an analgesic control device that can monitor respiratory rate and blood oxygen saturation. When the respiratory rate is less than 8 times / min and the blood oxygen saturation decreases, it can automatically alarm and the infusion will be automatically closed.
