Abstract

The invention relates to the field of medical instruments, and particularly discloses a patch type indwelling system. The system at least comprises a transmitting unit, a puncture unit and an patch type indwelling unit; wherein an accommodating cavity is formed in the bottom of the puncture seat, a plurality of elastic clamping arms are arranged on the side wall of the accommodating cavity, and convex parts are arranged at the free ends of the elastic clamping arms; an annular cavity is formed in the side, away from the containing cavity, of the puncture base; and an annular boss matched with the annular cavity is arranged in the transmitting unit. According to the structure, in the pre-emitting state, the elastic clamping arm deforms under the action of the convex part, the elastic clamping arm fixes the indwelling unit, and when the protective sleeve and the release paper are removed, the patch type indwelling unit cannot be separated from the puncture unit; at the puncture position, the elastic clamping arm is separated from the convex part and recovers to the initial state, and the elastic clamping arm and the indwelling unit are detached, so that the puncture unit and the patch type indwelling unit can be separated more easily without stretching skin through the patch type indwelling unit.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an application type indwelling system. Background technique [0002] The applicant’s previous patent application CN113082362A discloses a split-type application subcutaneous soft needle and a puncture method, wherein the split-type application subcutaneous soft needle includes a puncture assembly and a launch assembly, and the puncture assembly includes an application unit and a puncture unit. [0003] Above-mentioned structure has following technical defect: [0004] (1) The puncture unit is provided with a cavity for accommodating the application unit, and the cooperation between the application unit and the cavity needs to meet: in the ready-to-launch state, during the process of removing the protective sleeve and the isolation layer, the application unit must keep In the cavity of the puncture unit; after firing, the application unit remains on the skin, and the puncture unit...
