A patient care system in which a physiological parameter of a patient is monitored while the patient self-administers analgesic. A display presents a trend of the patient's physiological parameter along with the time of self-administration of the analgesic (“PCA”—patient controlled analgesic) such that the effect of the analgesic on the physiological parameter can be seen over selectable time periods. The physiological parameter may be ETCO₂ or SpO₂ or other. Also included is a drug library having acceptable pumping parameters as well as other PCA specific data. Should the operator program a pumping parameter that is outside an acceptable range, or should the patient attempt to self-administer more analgesic than the acceptable range permits, or should a patient's physiological parameter change during infusion such that a pumping parameter becomes outside an acceptable range, an indication of such will be given and action, such as stopping the pump, will be taken.

The method of reducing pain in a patient by combining a traditional pharmacological treatment with electro-acupuncture or percutaneous electrical nerve stimulation therapy. The pharmacological treatment consists of using analgesics such as morphine sulfate and hydromorphine provided to patients around the clock or as needed for pain. The patient controlled analgesia pump (PCA) is used by patients for self-administering of analgesia as needed. After patient stops using PCA pump narcotic and non-narcotic pain medications are administered mostly orally. Typically, there are two pairs of needle electrodes, two on each leg, connected to two separate outputs of the portable electrical stimulator. The constructions of the needle holder and the stimulator allow a patient to move freely and, if necessary, to carry the device during the entire day.

A security device for a patient-controlled analgesia (PCA) device receives a word or series of words spoken into it as a command by a patient and creates a voice print characteristic of the patient. A subsequent receipt of a voiced command is converted into a test voice print and compared to the patient's voice print. If the system identifies the test voice print as belonging to the patient's voice, it signals the PCA that the patient is requesting a bolus of medication from the PCA. If the device determines that the test voice print does not correspond to that of the patient, the device does not signal the PCA and optionally emits an audible error tone. In this manner, unauthorized people cannot give the patient a bolus dose from the PCA.

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 the technical field of analgesia patient controlled analgesia (PCA) pumps, in particular to an analgesia PCA pump based on fuzzy mathematics judgment for pain degree of analgesia. In the field of pain treatment by using the analgesia PCA pump, PCA press information of a patient is delivered through wireless transmitting and receiving. In a computer terminal, due to surgery patient individual differences and psychological and physiological differences of patients, a concept of fuzzy mathematics is introduced, patient-controlled fuzzy analgesia index (PCFAI) is put forward, and an analgesia pump platform is passed through adoption of fuzzy mathematics judgment for pain degree of analgesia. Through the analgesia pump platform, medical staff can monitor pain and analgesia condition of patients in the shortest time and optimize analgesia dosage schedule in time.

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.

A system for monitoring patient control analgesia (PCA) is provided. The system is used with or without a web page at bedside or a remote end. With the system, patients obtain good pain caring; doctors are provided with abundant reference data; and vendors get controls on device logistics.

A patient controlled analgesia device generally includes: a patient controlled analgesia pump and a biometric authentication system. The biometric authentication system generally includes a biometric pump controller coupled to the patient controlled analgesia pump that activates the patient controlled analgesia pump to deliver analgesia and a biometric switch adapted to receive a biometric input and operably coupled to the biometric pump controller to activate the biometric pump controller. A biometric authentication processor in the biometric pump controller activates the patient controlled analgesia pump to deliver analgesia only upon authenticating the biometric input received at the biometric switch. Optionally, the biometric pump controller also includes a dosing processor that limits delivery of analgesia according to a prescription.
