Description
Technical field
The utility model relates to technical field of medical equipment, and in particular to a kind of Internal Medicine-Oncology drug delivery device.
Background technique
The currently used means of oncotherapy mainly carry out control treatment by taking related drugs, but this biography
Uniting, not only the period is longer for application method, but also because is to carry out drug absorption by digestive system not to swell directly against internal medicine
Tumor affected part is administered, and is often worked slowly, and control effect is unobvious, to need prolonged treatment, increases patient
Burden, make troubles to patient.
In traditional medical procedure, passing through artery administration, injection contrast agent, central vein nutrition, venous blood collection, anticancer
It is administered either systemically or locally, chest, abdomen drainage etc. whens, mostly use plug in duct to carry out, and this plug in duct be easy infection, behaviour
It is inconvenient to make, and reliability is low, hinders the deficiency of patient's action etc..To solve the above-mentioned problems, it is administered at present using embedding pump in vivo,
Pump housing implantation is subcutaneous, and conduit can pass through selected artery, vein or intracavitary (including abdominal cavity, thoracic cavity, pelvic cavity etc.) various approach
The specified location for reaching lesion injects medical fluid through the puncture window of the embedding pump of skin penetrating with injection needle, can repeatedly, for a long time, instead
Multiple dabbling drug, it is smaller than the toxic side effect of Formulations for systemic administration by selected approach target administration, and also local drug concentration is high, and it can be straight
It is connected to up to diseased region, strong to cancer cell lethality, the treatment curative effect of other administrations is also preferable, can avoid conventional cannula and the external world
Contact causes to infect, avoids the vascular sclerosis necrosis caused by puncturing for a long time in vein blood vessel, and patient can it is as usual movable, wash
Bath, swimming etc.；Especially during pumping vascular drug delivery by artery, artery pump-type conduit is equipped with into endovascular front end to be split
Gap type check valve makes artery catheter pump have anti-reflux, not blood back effect in blood vessel, prevents bolt after artery catheter pump blood back
It fills in and leads to plugging.But there is also following disadvantages in use for the above-mentioned prior art: 1, the selection of material, processing technology
Selection, clinical application method are improper, and when use is easy to happen the phenomenon of leakage, and causing local drug flow to enter the human body makes the big face of skin
Product necrosis, brings injury to patient.2, conduit is combined with the nozzle that connects of the pump housing for socket, outside elastic pipe collar banding, fix tightly
Soundness is lacking, slightly external impacts or misoperation, and there is a possibility that conduit connects nozzle with pump head separates, this is same to patient
It is to bring injury.3, the design of traditional structure not can guarantee the various chamber pressure requirements of clinical application.
Therefore, in conclusion existing Internal Medicine-Oncology drug delivery device exists, structure is complicated, administration is unstable, using inadequate
Safety and the low problem of administration rate.
