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.

A mechanical patient-controlled analgesia device for injecting medicine into a patient's IV, includes an IV reservoir and a syringe communicated to the IV reservoir and having a syringe plunger. A mechanical biasing element is provided for exerting bias on the syringe plunger in a first syringe-filling direction to draw medicine from the IV reservoir into the syringe. An injection plunger is operable by the patient to move the syringe plunger in a second injection direction against the bias to inject the medicine in the syringe into a patient's IV. The injection plunger is movable independently of the syringe plunger and is engaged with but unconnected to the syringe plunger when the patient moves the injection plunger to inject the medicine. The patient can inject only a calibrated amount of medicine drawn into the syringe as determined by calibration of the biasing element and a metering element for a given viscosity of the medication.

Disclosed is a method for quantitative analysis for angiogenesis of living animals. The method includes steps of 1), CT (computed tomography) imaging in specified area of the living animal; 2), segmentation of vascular data; 3), fluorescence molecular tomography in the specified area of the living animal; 4), selection of CT images of the vascular in the specified area of the living animal; 5), analysis of vascular topology structure parameters by the aid of a sparse PCA (patient controlled analgesia) technology; 6), quantification of the angiogenesis. By the method, the quantification of the angiogenesis of the living animal can be achieved. The vascular in an angiogenesis area is selected by means of the fluorescence molecular tomography, precise quantification of the angiogenesis can be achieved based on the sparse PCA technology, and a quantitative method of the angiogenesis can be devised by the aid of the sparse PCA technology. During the quantification, different weighted values are distributed to each of the vascular topology structure parameters according to processing results of the sparse PCA technology, and contribution degrees of the different vascular topology structure parameters are distinguished.

The invention relates to an individualized smart patient-controlled analgesia pump which is capable of automatically increasing or reducing basic infusion speed and single infusion dosage to satisfy the self-analgesia requirements. The feedback adjuster of the analgesia pump can feed back to a microcomputer when the use condition and long-term idle condition of a patient-controlled button reach the set condition, the microcomputer automatically increase or reduce basic infusion speed and patient-controlled single infusion dosage according to preset parameters so as to reach the analgesia drug dosage required by the patient, and insufficient analgesia or unnecessary side effects caused by excessive analgesia can be avoided. The individualized smart patient-controlled analgesia pump has the advantages that the analgesia pump is provided with a clock and an infusion recorder, the infusion conditions of the whole operation process of the analgesia pump can be recorded, when gear up operation and gear down operation are performed, the basic infusion speed of each gear, and when the patient-controlled single infusion is performed and the dosage of the single infusion can be recorded by using time as the axis, the operation condition of the whole analgesia process can be clearly displayed through a display face, and doctor evaluation is facilitated.
