Drug delivery device for oncology department

Abstract

The invention discloses a drug delivery device for oncology department. The device comprises a drug delivery tube and a guide tube, wherein one end of the drug delivery tube is matched with a push rod, and a disc-shaped protrusion, which is integrally connected, is arranged at the other end of the drug delivery tube; the disc-shaped protrusion is matched with a groove formed in one end of the guide tube; the push rod extends into the drug delivery tube end and is fixedly connected with a push block; a sliding groove and a bearing are fixedly formed in one side in the drug delivery tube; a sliding block is matched in the sliding groove; the sliding block is connected with a rotary rod extending out of the sliding groove; a rotary disc is fixedly sleeved to the outer side of the bearing; the other end of the rotary rod is fixedly connected with the rotary disc; the lower part of the middle of the rotary disc is fixedly connected with a soft stirring rod; and a heating sheet is arranged between the outer wall and the inner wall of the horizontal section of the drug delivery tube close to the disc-shaped protrusion. The injection flow can be controlled, so that the drug delivery is more stable, and discomfort to human bodies is avoided; and as the guide tube is provided with a pointed design, the guide tube can be quickly penetrated into the bodies.

Description

technical field [0001] The invention relates to detection equipment, in particular to a drug delivery device for medical oncology. Background technique [0002] In the traditional medical process, through arterial administration, injection of contrast medium, central venous nutrition, venous blood collection, anti-cancer systemic or local administration, thoracic and abdominal drainage, etc., the insertion catheter is often used. Catheters are prone to infection, inconvenient to operate, low in reliability, and hinder the movement of patients. In order to solve the above problems, at present, the drug is administered with an embedded pump in the body, and the pump body is implanted subcutaneously, and the catheter can reach the predetermined site of the lesion through various channels of selected arteries, veins or intracavity (including abdominal cavity, chest cavity, pelvic cavity, etc.) , use the injection needle to inject the drug solution through the puncture window of...

AI Technical Summary

Problems solved by technology

But above-mentioned prior art also has following shortcoming in use process: 1, the selection of material, the selection of processing technology, clinical use method are improper, and leakage phenomenon easily takes place during use, causes local medicine to flow into flesh and makes skin large area necrosis, cause harm to the patient

2. The nozzle of the catheter and the pump body is a socket combination, and the outside is tightened with an elastic pipe hoop. The fixation is lacking. A slight external impact or improper operation may cause the catheter to separate from the nozzle of the pump head. It is also harmful to the patient

3. The traditional structural design cannot guarantee various lumen pressure requirements for clinical applications
