Multi-angle adjusting type micro-adjustment drug delivery device for medical oncology

Abstract

The present invention relates to the field of medical devices and particularly to a multi-angle adjusting type micro-adjustment drug delivery device for medical oncology. The multi-angle adjusting type micro-adjustment drug delivery device for the medical oncology comprises a drug delivery cylinder, an inner cavity of the drug delivery cylinder is divided into a transmission cavity and a drug delivery cavity, a liquid outlet head is arranged at a bottom part of the drug delivery cavity, a piston sheet is arranged in the drug delivery cavity, a push rod is arranged on a rear plate surface of the piston sheet, a liquid delivery pipe is externally connected to the liquid outlet head, a transmission disk is arranged in the transmission cavity, a bending support rod is arranged at a disk surface axis position of a disc surface of the transmission disk, a front rod end of the bending support rod is connected with the push rod through a connecting bolt, a clamping frame is arranged at a bottom part of the drug delivery cylinder, and a screwing disk is arranged at a top part of the clamping frame. The multi-angle adjusting type micro-adjustment drug delivery device can transform a large margin transmission input distance into a small margin transmission output distance, thus accurately control output of dosage, can also adjust angles and tightness of clamping and is fit for coping various limb tumors.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multi-angle adjustable fine-tuning drug delivery device for medical oncology. Background technique [0002] Targeted drug delivery is one of the most effective ways to reduce drug toxicity and improve efficacy because it can selectively deliver drugs to the target site, increase the concentration of drugs on the lesion, and reduce the accumulation in normal tissue cells. In the growth stage, tumors generally attach to arteries and other blood vessels, and connect with blood supply vessels of the human body through their own growth vessels to supply the growth of the tumor itself. In the existing treatment technology, through inhibitors targeting tumor blood vessels, cutting off the nutrient supply of tumors has achieved therapeutic effect. effect, but through conventional drug injections, the effect is poor.

Problems solved by technology

In the growth stage, tumors generally attach to arteries and other blood vessels, and connect with blood supply vessels of the human body through their own growth vessels to supply the growth of the tumor itself. In the existing treatment technology, through inhibitors targeting tumor blood vessels, cutting off the nutrient supply of tumors has achieved therapeutic effect. effect, but through conventional drug injections, the effect is poor

Using an external magnetic field to control the active area of ​​anti-tumor magnetic nanoparticle drugs can effectively increase the drug concentration in the treatment area, but it needs to be controlled by external magnetic field equipment for a long time, the regulation is complicated, and the freedom of patients is limited during treatment.

[0003] Chinese patent (authorized announcement number: CN107497039A) discloses a drug delivery device for medical oncology. The magnetic ring can slide and adjust the position on the fiber tube by the suction force of the external magnetic field; however, there are certain defects in this patent. Insufficient range and inability to adjust from multiple angles to the target to be administered
