Abstract: Provided is an autologous culture method of autologous stem cells according to an embodiment of the present disclosure, the autologous culture method including: (a) accommodating one's own stem cells collected by a medical institution and a first culture medium in a first culture container from the medical institution to a one's own culture device; (b) controlling the culture device to establish an environment suitable for culture of stem cells; (c) observing the stem cells cultured in the first culture container of the culture device; (d) replacing the first culture medium in the first culture container; (e) separating cultured stem cells from the first culture container; and (f) accommodating separated stem cells in a second culture container with a second culture medium.

Abstract: Provided is a centrifuge including: a rotary chamber configured to rotate so that centrifugal force acts on a substance contained in the rotary chamber; a storage unit configured to store a certain component separated from the substance in the rotary chamber by the centrifugal force according to rotation of the rotary chamber; and a filter located between the storage unit and the rotary chamber and through which the certain component, which is separated from the substance in the rotary chamber by the centrifugal force according to the rotation of the rotary chamber, passes to be stored in the storage unit. The storage unit includes a return prevention unit configured to prevent the certain component, which is separated from the substance in the rotary chamber by the centrifugal force according to the rotation of the rotary chamber and is stored in the storage unit, from returning from the storage unit to the rotary chamber.

Abstract: According to the present invention, the size of a droplet ejected to a target area is minimized to obtain high printing resolution, and effects of attraction and adhesive forces acting between a nozzle and air resistance can be minimized so that the target area is finely controlled to obtain high printing precision. An inkjet printing apparatus according to the present invention includes an ejecting device ejecting a droplet of a solution to a target area; and a light irradiating device irradiating light onto the droplet at an acute angle with respect to a line going through the ejecting device and the target area to heat and evaporate a part of the droplet before the ejected droplet reaches the target area, so that the droplet is accelerated along the line.

Abstract: A syringe for fat tissue components distinction including a specific gravity distinction member, and a fat tissue components separating method using the syringe. The syringe for distinguishing crude fat tissue components extracted from the human body into several fat tissue layers by specific gravity includes: a syringe main body in a cylindrical shape for storing the crude fat tissue components extracted from the human body, the syringe main body having a fat intake hole at a front end and an opening at a rear end; and a specific gravity distinction member disposed in the syringe main body and having a specific gravity smaller than about 1.0, wherein the specific gravity distinction member is movable into one of the fat tissue layers that has the same specific gravity as that of the specific gravity distinction member, thereby enabling fat tissue components distinction by specific gravity.

Abstract: A syringe piston used in fat transplantation is structured such that free oil is easily separated from suctioned fat by a syringe piston having a filter and naturally discharged through the rear side thereof. The syringe piston without a shaft, used in fat transplantation, disposed in a syringe-shaped cylindrical vessel, includes a piston body without the shaft, a packing coupled with an outer surface of the piston body to seal between the piston body and the syringe-shaped cylindrical vessel, a free oil discharging hole communicated with the front side and the rear side of the piston body, an opening and closing device for opening and closing the free oil discharging hole, and a filtering device disposed in a passage through which free oil is discharged to filter fat and pass the free oil.
