Detailed Description

The utility model will be described in further detail with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present utility model, and a detailed implementation is given, but the scope of protection of the present utility model is not limited to the following embodiments.

As shown in fig. 1 and 2, an automatic drug feeding microneedle for scar treatment according to the present embodiment includes: the medicine storage device comprises a handle 1, a medicine storage bag 2, a needle mounting port 3, a micro needle 4, an outlet plug 5, a connecting column 6, a core ball 7 and a medicine storage space 8; wherein, store up medicine bag 2 parcel outside core ball 7, store up the space between medicine bag 2 and the core ball 7 and be the medicine storage space 8, be provided with export stopper 5 below core ball 7, core ball 7 top is provided with spliced pole 6, spliced pole 6 top is the design of slick and sly cambered surface, store up medicine bag 2 parcel outside spliced pole 6, handle 1 inside is hollow structure, handle 1 interior hollow cup joints at the spliced pole 6 top that the parcel has medicine bag 2 and closely laminate, handle 1 sets up in medicine bag 2 outside, handle 1 interior hollow just can press from both sides at the connecting rod 6 top to press from both sides medicine bag 2 in the middle of handle 1 and spliced pole 6 head, and because medicine bag 2 adopts high elasticity medical transparent rubber material to have elastic properties, therefore medicine bag 2 can not take place the circumstances of breaking. A needle mounting opening 3 is arranged below the medicine storage bag 2, an outlet plug 5 below the core ball 7 is plugged into the needle mounting opening 3 of the medicine storage bag 2, and a micro needle 4 is inserted into and mounted at the needle mounting opening 3.

An automatic drug feeding microneedle for scar treatment according to this embodiment is shown in fig. 1. The appearance of the medicine bag is divided into a miniature transparent medicine storage bag, a micro needle and a miniature handle.

A rear interior perspective view of the drug reservoir is shown in fig. 2. Firstly, the outermost layer in the scheme adopts a high-elasticity medical transparent rubber material to manufacture a bag body of the medicine storage bag 2, and the medicine storage bag 2 is tightly wrapped on the inner core ball 7 before medicine storage; secondly, the inside of the bag body of the medicine storage bag 2 is made of medical hard plastic, a connecting column 6 is arranged above the ball body of the core ball 7 and is connected with the bag body of the medicine storage bag 2, so that the core ball 7 can be prevented from rolling inside, an outlet plug 5 is arranged below the core ball 7, when a medical staff pushes a selected medicine into the medicine storage bag through a needle mounting opening 3, a handle 1 outside the connecting column can be clamped by an instrument, as the medicine storage bag 2 is clamped between the handle 1 and the connecting column 6 and tightly attached, a stronger friction force exists, the movement condition does not occur, then the outlet plug 5 is plugged into the needle mounting opening 3 for sealing operation, the bag body of the medicine storage bag 2 is made of transparent materials, in addition, the inside of the needle mounting opening 3 is in a funnel shape towards the direction of the medicine storage bag 2, namely, the opening towards the direction of the medicine storage bag 2 is large, the micro needle 4 is small, the micro needle 4 is conveniently mounted from a thin end when the needle is mounted outside, even if the inside is not seen, the micro needle 4 is completely mounted from the thin end, and after the sealing operation is completed, all injection preparations can be completed before the micro needle 4 is inserted into the needle mounting opening 3; thirdly, the outlet plug 5 is required to be pulled out from the inside of the needle mounting port 3 during injection, so that the stored medicine liquid is automatically pressed out of the needle mounting port 3 by the internal pressure and injected into the affected part through the needle. The ball ring gap between the core ball 7 and the medicine storage bag 2 bag body is the medicine storage space 8, and as the medicine storage bag 2 bag body is made of high-elasticity rubber, the rebound force for recovering the original shape exists, and after all medicines are discharged, the inner core ball 7 can ensure that the medicine storage bag 2 bag body still has great rebound force, so that the condition that excessive medicines are remained in the medicine storage space 8 is avoided. Fourth, the patient can prepare a plurality of micro-needles from the hospital according to the scar area at a time, and the micro-needles are injected at different parts of the scar, and because the micro-needles are extremely small in size and have no risk of being injected into the skin too deeply, the patient only needs to uniformly distribute the micro-needles on the scar area and fix the micro-needles by using adhesive tapes.

In the foregoing, the present utility model is merely preferred embodiments, which are based on different implementations of the overall concept of the utility model, and the protection scope of the utility model is not limited thereto, and any changes or substitutions easily come within the technical scope of the present utility model as those skilled in the art should not fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
