Problems solved by technology

[0003] The injection seat of the infusion port is generally round, and it is not fixed but in a free state when implanted under the skin. Therefore, when infusion is given to the patient, the injection seat of the infusion port is easy to move under the patient's skin, causing the infusion needle to puncture easily. The upper edge of the infusion port injection seat prevents the infusion needle from communicating with the interior of the infusion port injection seat, and cannot ensure that the infusion needle can be smoothly inserted into the interior of the infusion port injection seat for infusion for the patient. seat fixture

Abstract

The invention discloses an infusion port injection holder fixing device. The infusion port injection holder fixing device comprises a main structure, a limiting structure and a protecting structure, wherein the limiting structure is mounted onto the upper portion of the main structure, and the protecting structure is mounted at the bottom of the main structure; the main structure comprises a roundfixing plate, an upper convex ring, a lower convex ring, and a first notch penetrating the round fixing plate, the upper convex ring and the lower convex ring; the upper convex ring is integrally arranged in the top center of the round fixing plate, the lower convex ring is integrally arranged in the bottom center of the round fixing plate, and the inside of the lower convex ring is communicatedwith the inside of the upper convex ring; the limiting structure comprises a ring-shaped mounting base, a cylinder, a round plate, and a second notch penetrating through the ring-shaped mounting base,the cylinder and the round plate. The infusion port injection holder fixing device can prevent an infusion port injection holder from moving subcutaneously in the patient and an infusion needle frompuncturing the upper edge of the infusion port injection holder and ensure that the infusion needle can be smoothly inserted into the infusion port injection holder for infusion of the patient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a fixing device for an injection seat of an infusion port. Background technique [0002] The infusion port (implantable venous access port, PORT) is a closed infusion device that is completely implanted in the human body, including a catheter part with the tip located in the superior vena cava and an injection seat implanted under the skin. [0003] The injection seat of the infusion port is generally round, and it is not fixed but in a free state when implanted subcutaneously. Therefore, when infusion is given to the patient, the injection seat of the infusion port is easy to move under the patient's skin, causing the infusion needle to easily puncture The upper edge of the infusion port injection seat makes the infusion needle unable to communicate with the interior of the infusion port injection seat, and cannot ensure that the infusion needle can b...
