Multi-mode patient controlled analgesia pump

Abstract

A multi-mode patient controlled analgesia pump capable of independently infusing different medicines to a plurality of different effect positions at the same time mainly comprises a microcomputer control main body and a plurality of independent infusion units, wherein the independent infusion units are externally connected with a plurality of different effect positions, and each independent infusion unit is formed by connecting a medicine infusion pump, a medicine storage device and a corresponding infusion connecting pipeline. According to the multi-mode patient controlled analgesia pump, different medicines can be stored in the infusion units and are infused to the different effect positions of inside of the canalis vertebralis, the peripheral nerve trunk, a subcutaneous area, a vein channel and the like in the manners of continuous infusion, interrupted infusion, combination of the continuous infusion and the interrupted infusion, user self-controlled single infusion and the like, so that continuous analgesia in the multiple modes is achieved. By means of the multi-mode patient controlled analgesia, the multi-mode patient controlled analgesia pump reduces the concentration and dose of the required medicines and side effects of the medicines, has a better analgesic effect, can effectively solve the problems that a medical infusion analgesia pump for the single effect position is poor in analgesic effect, and the medicines have large side effects.

Description

technical field [0001] A new type of self-controlled analgesic pump for medical use, which can provide continuous multimodal analgesia. Background technique [0002] Current medical self-controlled analgesia pumps can only be connected to one active site for continuous analgesia, and most of them are for continuous analgesia in the spinal canal or intravenous continuous analgesia. However, this analgesic method cannot completely solve the pain problem, and increasing the dose or concentration of the drug often brings many side effects, such as itching, nausea and vomiting, urinary retention, excessive sedation, decreased muscle strength, limited movement, and even poor circulation. stable etc. [0003] Since there is currently no one analgesic method that can completely solve the pain problem, multimodal analgesic methods have become the consensus of experts in the industry. At present, the combined application of multiple drugs is very common. Continuous multimodal analge...

Problems solved by technology

However, this analgesic method cannot completely solve the pain problem, and increasing the dose or concentration of the drug often brings many side effects, such as itching, nausea and vomiting, urinary retention, excessive sedation, decreased muscle strength, limited movement, and even poor circulation. stable etc.

[0003] Since there is currently no one analgesic method that can completely solve the pain problem, multimodal analgesic methods have become the consensus of experts in the industry. At present, the combined application of multiple drugs is very common. Continuous multimodal analgesia with multiple channels and multiple action sites can only be used in the form of continuous analgesia with a single injection combined with a self-controlled analgesic pump acting on another site. Achieving sustained multimodal analgesia with certain limitations
