Description
Technical Field
The invention relates to the field of medical equipment, in particular to a control device and a control method of an analgesic pump.
Background
The common electronic analgesic pump is a peristaltic extrusion type anesthesia infusion device and comprises a pump head and a single medicine bag, a driver which acts according to a program is arranged on the pump head, a liquid inlet and outlet guide pipe is connected to the medicine bag, a section of flexible hose is arranged on the liquid inlet and outlet guide pipe, anesthesia and analgesia liquid medicine can be output from the medicine bag through the liquid inlet and outlet guide pipe when the device works, when the pump head is connected with the medicine bag, a push rod on the pump head just abuts against the outside of the flexible hose and works according to the program, and the anesthesia and analgesia liquid medicine is output through the flexible hose and injected into a human body to realize continuous anesthesia and analgesia of a patient.
Under the guidance of the ideas of multi-mode analgesia and balanced analgesia, the drugs commonly used in analgesic pumps mainly comprise two parts: 1. opioid analgesics and antiemetics, 2, non-opioid analgesics (mainly non-steroidal drugs). The opioid in the analgesic pump can cause side effects such as nausea and vomiting and skin itch, so the opioid and the antiemetic are usually used together, and according to statistics, the total probability of nausea and vomiting after operation of a patient is 30% -50%, and in certain people with high risk factors, the incidence rate of PONV is more 80%, and the side effects of nausea and vomiting can cause other problems such as dehydration, electrolyte imbalance, wound cracking and bleeding, so that the residence time of the patient in the hospital after operation is prolonged, the medical cost is increased, and the treatment experience of the patient is greatly influenced.
In analgesic infusion, improper administration or overdosing of analgesic drugs may cause excessive sedation of the patient, and brain function may be inhibited, which may seriously affect physiological stability of circulatory system, and in serious cases, infusion accidents such as central nerve inhibition, respiratory depression, heartbeat inhibition, etc. may occur. Especially, the infusion of opioid analgesics may lead directly to respiratory and cardiac arrest.
Current analgesic pumps are basically not equipped with the function of monitoring the side effects of analgesic infusion, mainly by means of manual monitoring. In practical, the analgesic pump capable of performing individual intelligent automatic control monitoring generally performs infusion control on the analgesic pump by pressing an automatic control button by a patient (such as the Chinese patent ZL 2014100293286), the function of monitoring the body of the patient cannot be realized, once side effects are generated due to excessive medication or unreasonable medication, the patient is completely felt by the patient and the doctor continuously inquires the patient to prevent accidents, and if the infusion can be recognized and suspended or the infusion speed is reduced at the initial stage of the side effects, and an alarm means is overlapped, the probability of the accidents caused by the side effects can be greatly reduced.
In order to improve monitoring and recognition capability, chinese patent ZL2015202585950 provides an analgesic pump control scheme, including sedation depth detection module, respiratory frequency detection module, blood oxygen detection module, input module, display module etc., through monitoring whether there is abnormality in the signal, in time stop analgesic pump work or reduce infusion speed, effectively avoid because of the infusion of analgesia breaks out, however, in above-mentioned such scheme, still there is huge leak: when the user body is in a problem and is inconvenient to give a speed activation instruction to the input/output module or the input/output module fails, the signal processing module does not acquire a speed activation signal, so that the analgesic pump cannot infuse according to a certain infusion speed or immediately stop infusing, and the health and safety of the user are difficult to ensure.
