The utility model discloses an autologous repair microneedle
injector, which relates to the technical field of
medical instruments and comprises a
liquid storage tube, a pushing mechanism is arranged in the
liquid storage tube, the bottom of the pushing mechanism is fixedly connected with a blocking block, the blocking block is inserted into the lower side wall of the
liquid storage tube in a sliding manner, a microneedle liquid penetrating head is fixedly mounted on the bottom surface of the blocking block, and the microneedle liquid penetrating head is fixedly connected with the liquid
storage tube. A limiting head is fixedly installed on the bottom face of the liquid storage
pipe, the micro-needle liquid penetrating head is arranged in the limiting head, a through hole is formed in the surface of the lower side wall of the limiting head, the specification of the micro-needle liquid penetrating head is matched with that of the through hole, an
extrusion mechanism is arranged in the liquid storage
pipe, and a liquid adding
assembly is arranged on the side face of the liquid storage
pipe. Through cooperation of the
extrusion mechanism and other mechanisms, rapid connection of microneedle
puncturing and repairing
stock solution coating is achieved, the repairing
stock solution can enter a wound in time, the
skin repairing effect after a microneedle operation is guaranteed, and the situation that the
coating opportunity is delayed due to the fact that the self-flowing speed of the repairing
stock solution is low is avoided.
