Skull implant type drug injection port

Abstract

The present invention relates to a skull implant type drug injection port comprising: a holder which is placed on the upper section of a port insertion hole formed in the skull of a patient and has a drug injection hole formed on the upper surface thereof; a drug injection diaphragm which is provided so as to seal the drug injection hole of the holder and into which a syringe needle for injecting a drug is inserted; a drug storage part combined with the lower section of the holder, for storing the drug inserted through the drug injection diaphragm; a drug discharge pipe which is connected to the drug storage part so as to discharge the drug stored in the drug storage part; and a rib which is formed on the outskirt between the holder and the drug storage part and has a diameter larger than the inner diameter of the port insertion hole, wherein the height ratio of the holder to the drug storage part is 1:0.5 to 0.6 on the basis of the rib. The present invention relates to a skull implant type drug injection system comprising: a skull implant type drug injection port; and a guide needle which is attachable to and detachable from the drug discharge pipe by passing through the drug injection diaphragm of the skull implant type drug injection part, wherein the guide needle has a protruding section formed on an area which is separated at a predetermined distance from a cutting-edge section.

Description

technical field [0001] The invention relates to the ability to pass medicine injected from outside the human body through a medicine discharge tube Skull implants discharged into the human body Drug injection port. Background technique [0002] Generally, body-implanted drug injection ports are devices developed for patients with diseases that require continuous or intermittent drug injections to be performed continuously over a long period of The medicine injected from the outside is simultaneously discharged to a desired part through the medicine discharge tube in the patient's body. [0003] Cancer patients are patients who need to continuously perform continuous or intermittent drug injections. In addition to periodic injections of anticancer drugs used for treatment, 50% of all cancer patients require additional injections of analgesics to relieve pain. [0004] Body-implantable drug injection ports can be applied to cancer patients as described above, as well as ...

Problems solved by technology

However, since the reservoir in this technique is formed of a plastic material, its strength is low, and it is difficult to feel the reservoir by touch under the scalp

In particular, when the drug is injected repeatedly, drug leakage frequently occurs under the scalp due to the fragile material membrane of the upper hemisphere of the reservoir
