The invention discloses an auxiliary needle inserting device for an application type continuous subcutaneous drug delivery system, and relates to the field of medical instruments. The ejection needle inserting guide cylinder is arranged in the bottom sleeve in a sleeved mode, a plurality of guide beams are symmetrically arranged on the inner side wall of the ejection needle inserting guide cylinder, a plurality of wedge-shaped beams are vertically arranged at the bottom of the ejection needle inserting guide cylinder in a surrounding mode, and the puncture steel needle pulling-out guide cylinder is sleeved with an injection power spring fixedly connected with the inner bottom of the bottom sleeve. The injection indwelling soft needle base is provided with a base main body end part, an opening guide groove is formed around the base main body end part, and a connecting limiting column is arranged on the injection indwelling soft needle base. The device is exquisite in structure, the puncture steel needle can be selected to be pulled out of the guide cylinder to trigger the puncture needle inserting action, the puncture steel needle is automatically pulled out after puncture is in place, the injection soft needle is reserved at the injection position, small built-in automatic needle inserting of the application type continuous subcutaneous drug delivery system is achieved, pollution is avoided, pain is relieved, and psychological fear of a user is reduced.
Description
technical field [0001] The invention belongs to the field of medical devices, in particular to an auxiliary needle insertion device for an adhesive continuous subcutaneous drug delivery system. Background technique [0002] In today's clinical treatment, it is often encountered that during the treatment of some diseases, patients need to be given uninterrupted timing and quantitative administration. For example, when treating diabetic patients, it is necessary to inject insulin regularly and quantitatively. . There are many structural types of existing continuous injection indwelling needles, mainly including manual needle sticking and automatic auxiliary needle sticking structures. For example, the application number is 202110399541.6, and the name is an invention patent of an automatic needle sticking aid for injection needles; The appearance design patent of the needle device. The existing manual needling operation is inconvenient and requires certain training and over...
