30 results about "Patient-controlled analgesia" patented technology

In a patient controlled analgesia (PCA) system, physiological data is processed and alarms are provided by the controller of the physiological module sensing the data according to a first rule. The physiological data is also processed by a second, separate controller according to a second rule independent from the first controller. According to the second rule, the physiological data may be filtered, processed with physiological data and non-physiological data obtained from another source, such as a remote server, and the PCA delivery device controlled to prevent delivery of medication accordingly. The provided system of multiple processors and rules enables normal alarming by physiological sensor modules while the pausing or prevention of the PCA delivery is controlled by a separate controller. Through this means, not only are false pauses and alarms for PCA delivery reduced, but the normal alarms of the monitors are permitted to function normally.

Clips or straps may be used to position a patient-controlled-analgesia (PCA) pump control in a position where a patient can easily operate a PCA pump. A strap that allows a PCA pump control to always be in hand or very close at hand is preferable to a strap or clip that merely keeps a PCA pump control nearby.

The invention discloses a patient-controlled analgesia pump and a control method thereof. The method comprises the following steps: setting an infusion speed with a continuous amount as a first speed, and starting infusion at the first speed; reducing the infusion speed with the continuous amount from the first speed; when external trigger information is received, performing infusion for a single-time infusion amount, and increasing the infusion speed with the continuous amount to a second speed which is faster than the infusion speed with the continuous amount when the external trigger information is received; reducing the infusion speed with the continuous amount from the second speed until the external trigger information is received. The patient-controlled analgesia pump provided by the invention reduces excessive analgesia by continuously reducing the infusion speed with the continuous amount, thereby not endangering the life and health of a patient.

The invention relates to a device for monitoring the pain state of a patient and a method thereof, the method comprises the steps of collecting patient odynolysis records of a patient from the clinical end in the wired or the wireless way, transmitting to the remote end via a transmission interface in the real-time or the non-real time way for data analysis and treatment and further carrying out analysis and feedback against treatment course feedback information of each user, the device comprises a patient PCA, a computer monitoring module, a network monitoring module and a network monitoring module database, and the device can further comprise a portable device and a PCA bluetooth wireless transmission module thereof. Therefore, clinical staff can integrate PCA information containing drug consumption and the pain state, and feed back the pain state of the patient in a real-time manner by leading the patient to visit the remote monitoring device, and has the characteristics of high postoperative service quality, complete medical records, low cost and capability of providing the basis for leading medical instrument manufactures to monitor market resource planning and assisting logistics and market development of the medical instrument manufactures.
