Compared with the prior art, the invention has the beneficial effects that:

1. the breast drug delivery device with the needle-free injection is convenient to wear and fix, can perform painless injection on nipples and perform needle-free injection on breasts, and is suitable for drug treatment of various breast diseases.

2. The wearable fixator can be fixed on the body of a patient in a splicing mode of the left part, the right part and the upper part of the nylon fastener tapes, and the left binding belt, the right binding belt and the upper binding belt which are elastic are arranged, so that the wearable fixator can easily adapt to patients with different body types, and is firm and comfortable in fixation and strong in universality.

Angle values can be marked on the annular dial, and length size values are marked on the strip-shaped sliding through hole along the sliding direction, so that the focus position can be determined, and the needle can be accurately applied.

4. The painless injection device can directly inject medicine to the nipple, and the injection of the medicine liquid is completed by placing a film medicine liquid bag in advance or continuously supplying the medicine through a pressure device. The painless needle head can pierce the stratum corneum barrier of the skin to generate the micro-channel to increase the penetration of the medicine, the medicine penetrates into the capillary vessel network of the dermis layer of the skin through the injection pore and directly reaches the treatment target position along with the blood circulation, the purpose of sufficient and rapid administration can be achieved, the dosage of the medicine is greatly reduced, and the curative effect of the medicine is improved. Because the micro-needle is thin and sharp, the general puncture depth is only on the stratum corneum and the upper layer of the dermis, and the nerve ending is not contacted, the damage degree to the organism tissue is reduced, and the papilla with densely distributed nerves can not generate severe pain, so as to achieve the purpose of painless injection.

5. A one-way retraction-preventing sealing valve is arranged in the lower end of the air extracting cylinder, and the valve core membrane relatively separates the space between the fixed cylinder and the air extracting cylinder, so that the nipple is prevented from retracting when the air extracting piston stops being drawn. In addition, can be as required in the nipple gets into the solid fixed cylinder back, inflate the ring through air pump or syringe for aerifing, make and aerify the tight nipple of hoop, the elasticity rubber card plays flexible ratchet's effect simultaneously, has been driven when the nipple gets into the solid fixed cylinder and has upwards turned up, if the nipple contracts, the elasticity rubber card is in order to be driven the rollback by the friction, can further squeeze tightly the periphery wall of nipple, realizes firm fixed effect.

6. When the needleless injector is used in a conventional state, the needle needs to be tightly pressed on the skin so as to enable the high-speed jet to instantly penetrate the skin to reach the subcutaneous part. However, the breast area is rich in glands and cannot be strongly compressed, especially in the case where the breast has developed lesions (such as swelling, fistulas, etc.), and cannot withstand strong compression. The original self-adsorption mechanism of the device can be tightly pulled and attached through three-stage adsorption, and the skin on the surface of the breast is adsorbed and fixed around the needleless injection head without causing extrusion injury to the gland inside the breast.

7. The needleless injection power device is designed to be in a pure mechanical power form, the size of needleless injection power is flexibly controlled according to different skin surface conditions of patients by controlling different compression degrees of the driving spring, and then the damage to the skin surface of the patient is avoided on the premise of meeting the injection force. The device is provided with the guide inner cylinder shell in the needleless injection outer cylinder shell, can provide vertical guide for the piston push rod, and avoids the phenomenon of shell clamping in the injection process to influence the medicine jet velocity and the injection effect.
