Description
Technical Field
The utility model belongs to the technical field of the infusion port device of dosing and specifically relates to an infusion port device of dosing.
Background
The port is a fully implanted, closed infusion system that is implanted in the body. The system includes a catheter with a device called an injection site attached to the end of the catheter. The drug delivery end of the catheter is placed in a target area through subcutaneous puncture through an operation, the other end of the catheter is connected with the injection seat, the injection seat is placed in subcutaneous tissues near a cavity and is sutured and fixed, only a small sutured wound is seen in the appearance of skin after the operation, and a protruding ball can be touched on the body surface of a patient after the healing and the stitches are removed. During treatment, the needle is positioned, the needle is vertically penetrated into a liquid storage tank of the puncture seat through the skin, and the liquid medicine is accurately delivered to a target area where the administration end of the catheter is positioned through the catheter. The port is designed to deliver the fluid to the target area, so that a seal and a secure connection are ensured from the injection site to the middle of the administration end of the catheter. Most of the connection structures of the infusion port and the catheter in the current market are in threaded compression connection, and the connection strength can be guaranteed, but the structure is complex and the operation is complex.
Intrathecal continuous infusion is an emerging way to treat cancer pain and other chronic pain, and more hospitals and patients in China begin to select intrathecal continuous infusion for treating chronic pain, and the principle is as follows: the drug administration end of the intrathecal catheter is embedded into the subarachnoid space, and is connected with the drug administration device in the body through a subcutaneous tunnel, and the drug administration device infuses the analgesic drug into the subarachnoid space to act on the action site of the spinal cord so as to achieve the purpose of relieving pain. In clinic, an implanted drug delivery pump is mostly adopted as a drug delivery device for continuous drug delivery, but the implanted drug delivery pump is expensive and has higher risk, and patients can take care when selecting the drug delivery pump, so that the timely treatment of the patients is influenced. In actual treatment, an external analgesia pump can be connected to the infusion port as a drug delivery device, the cost and the risk of the infusion port are lower than those of an implanted drug delivery pump, but the action of a patient is limited, and the quality of life is influenced.
