Technical Field

[0001] The utility model relates to the technical field of injection tools, and particularly to a medicine mixing device capable of connecting an ampoule. Background Art

[0002] With the continuous improvement of living standards and medical technologies, a large number of regenerative aesthetic medicine technologies such as hyaluronic acid injection and poly-L-lactic acid injection have emerged in recent years. That is, through methods such as drug injection and photoelectric stimulation, tissues such as cells, collagen, and fascia ligaments in the human body are activated and repaired, and fibroblasts are stimulated to produce collagen, so as to achieve the purpose of skin anti-aging and rejuvenation. Among them, Sculptra, as the first imported poly-L-lactic acid injection, uses micron-sized PDLLA microspheres as the main active ingredient, which is injected into parts such as skin soft tissues, and after processes such as degradation, activates and repairs the skin.

[0003] During the use of the above-mentioned poly-L-lactic acid injection, it is necessary to prepare the medicine containing PDLLA microspheres in advance and shake it well before injection preparation to ensure that the medicine is in a homogeneous state when it enters the skin tissue. However, in actual clinical operations, the on-site preparation and use of the poly-L-lactic acid injection are mostly carried out by drawing the medicine with a syringe and then mixing it, which is difficult to meet the requirements of the aseptic principle, consumes a lot of time and manpower, affects the medical treatment efficiency, increases the waiting time of patients, and is extremely likely to aggravate the anxiety of patients in the fast-paced modern medical environment, and also affects the trust and satisfaction of patients towards the treatment.
