Infusion method of multiple medicine and velocity and device thereof

Abstract

The invention relates to a method for infusing by various drugs at various speeds and a device thereof. The device at least comprises a pump body and an infusion vessel which is connected with the pump body, wherein, the infusion vessel is provided with a drug input terminal and a drug output terminal. The device is characterized in that the pump body is provided with a plurality of cavities, and the top of the pump body is provided with a drug puncture film; the infusion vessel is provided with a plurality of vessel cavities; at least one vessel cavity is communicated with one cavity; other vessel cavities are respectively communicated with the corresponding cavities; the outer side of the infusion vessel is provided with a plurality of drug storing sacks with high elasticity which are communicated with corresponding cavities through a plurality of drug input holes on the vessel cavities and are communicated with the drug output terminal of the vessel cavities through a plurality of drug output holes on the corresponding vessel cavities. The infusion device can realize the combination of infusing large doses of drug once and continuous infusing drug with low concentration, thus remaining required drug concentration required by treatment, being beneficial to improving treatment effect and improving the life quality of patients effectively owning to convenient operation. The invention has the advantages of easy processing and manufacture as well as low cost.

Description

technical field [0001] The invention belongs to the category of medical equipment, and relates to a method and a device for infusing multiple medicines at different rates. Background technique [0002] At present, the widely used drug infusion pumps are mostly embedded under the skin, and are used for chemotherapy or analgesia of tumor patients. They are used for long-term and regular drug administration in the patient's body, with concentrated drug effects, good curative effect and few side effects. However, in clinical medical work, it is often necessary to combine a single high-dose drug infusion with a continuous low-concentration drug infusion, which cannot be accomplished by the chemotherapy pump currently used in clinical practice. In view of this, the designer combined with the actual needs of clinical work, developed the present invention - a new dual-chamber drug sustained release infusion device, which can be implanted into the body with the whole pump during the ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the defects that the existing chemotherapy pumps cannot combine single large-dose drug infusion with continuous low-concentration drug infusion, the present invention provides a method and device for multiple-rate infusion of various drugs, through which the infusion device Not only can a single large-dose infusion of drugs quickly reach the peak value required for treatment, but it can also conveniently and effectively ensure the continuity of drug infusion and maintain the drug concentration required for treatment, which is conducive to improving the therapeutic effect. At the same time, it is easy to operate and avoid It is inconvenient for the patient to connect to the infusion set for a long time during continuous infusion, which effectively improves the quality of life of the patient
