Technical Field

The utility model relates to a washing watering can suitable for an autologous hair transplantation operation area.

Background

The area of the hair transplantation operation area is large, bleeding often occurs in the hair planting process and after the hair is planted, bleeding points are dense, the planting area can not be pressed by gauze to stop bleeding, the hair transplantation operation time is longer, the hair transplantation operation time is long and is not washed in time, and the bleeding is easy to form scab, so that the hair transplantation operation needs to be washed by a large amount of physiological saline. And after the wound is rinsed, adding growth factors for promoting wound healing.

Because of sterility requirements, only 20ml syringes can be used to remove the needle tip for the purposes of washing the blood crust, and the disadvantages of using 20 syringes are: the syringe has limited one-time aspiration; when a large amount of flushing is performed, a doctor needs to repeatedly suck and push, so that hand fatigue is easily caused; the pressure of the injector is not enough, and the blood crust at the washing part is not washed cleanly.

And if the watering can is used for flushing, the problem of suction quantity can be solved, a doctor does not need to repeatedly suck and push the watering can during a large quantity of flushing, the problem of hand fatigue can be solved, and the pressure is high enough during flushing, so that the blood crust can be easily flushed.
