A medical oncology drug delivery device

Abstract

The invention discloses a drug delivery device for medical oncology, which comprises a needle body, the inner side wall of the needle body is fixedly connected with a syringe, the inner side wall of the syringe is sealed and slidably connected with a piston, and the top of the piston is fixedly connected with a Push rod, the outer wall of the needle body is fixedly connected with a positioning block, the outer wall of the needle body is fixedly connected with a liquid medicine tank, the bottom of the liquid medicine tank is fixedly connected with a positioning seat, and the inner side of the liquid medicine tank is fixedly connected with a positioning block. The wall is sealed and slidably connected with a slide plate, and the top of the slide plate is connected with a dosing tube through a sealed slide connection. The present invention realizes the repeated absorption of the liquid medicine in the syringe through the pressure difference, which improves the injection efficiency of the diseased part of the patient and greatly improves the Reduce the pain of the patient, save the time of the medical staff, better ensure the stability of the connector by fixing and sealing the joint, and prevent the loss of the connector and the extravasation of the drug solution from causing damage to the patient's skin. damage, protecting the safety of the patient and improving the stability of the device.

Description

A medical oncology drug delivery device technical field [0001] The present invention relates to the technical field of tumor drug administration, in particular to a medical oncology drug delivery device. Background technique Tumor refers to a new organism formed by local tissue cell proliferation under the action of various tumorigenic factors. The new organisms are mostly mass-occupying lumps, also known as neoplasms. Studies have found that tumor cells will appear different from normal cells. At the same time, tumor cells themselves can adapt to the metabolic environment by switching between glycolysis and oxidative phosphorylation. According to the cell characteristics of new organisms and the degree of harm to the body, tumors are divided into benign tumors and malignant tumors. Malignant tumors can be divided into carcinomas and sarcomas. Carcinoma refers to malignant tumors derived from epithelial tissue, and sarcoma refers to mesenchymal tissue. Including fi...

Problems solved by technology

[0003] The traditional medical oncology drug delivery device basically injects a certain amount at one time. When re-injecting, it is necessary to pull out the device and re-sterilize and add medicine before re-injecting. This method is not only cumbersome to operate, but also makes the patient feel very uncomfortable. For this reason we propose a kind of oncology drug delivery device to solve the above problems
