BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clean bench, and relates to a plastic surgery cleanbench capable of inhaling fat using an inhaler in plastic surgery and separating the fat sucked into the inhaler to perform re-injection in aseptic conditions.

The method of using a syringe as a tool for inhaling and transplanting fat for molding has been widely known. However, since everyone injects and injects and injects fat with human power, it is not only inconvenient for use but also has a uniform injection speed. Doing so will adversely affect the performance of the procedure.

In order to solve this problem, a large amount of suction is used to manually collect fat, and a centrifuge is used to inject the centrifuged fat into a small syringe. The fat transplantation process was complicated and not only required a lot of effort, but also had a high possibility of contamination, which was undesirable.

In order to solve such a problem, an inhaler having an improved structure to pass only fat by improving the structure of the piston head of the inhaler has been proposed, but in reality, a centrifuge has to be used because of a low fat separation rate.

The present invention improves the structure of an inhaler capable of inhaling and injecting fat to enable the same inhaler to be used for inhaling and injecting, and to facilitate inhalation and infusion of fat using air pressure during molding.

In addition, by using the air pressure for suction and infusion of fat, at this time, the sucked fat and waste can be separated by using a centrifuge, and the pretreatment process can be collectively processed in a plastic surgery cleanbench. Doing.

Operation of the plastic surgery clean bench 40 of the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3 as follows.

First, the clean bench 40 is operated to extract the desired fat by centrifugation after liposuction in a sterile state, and the selected fat is injected into the body of the desired site for transplantation.

(1) Aseptic maintenance status

That is, when power is applied to maintain a sterile state and the clean bench 40 is operated through the key input unit 3, the blower motor 51 of FIG. 2 is driven to send air to the sterilization filter 52. Clean air passing through the sterilization filter 52 in the upper portion while being discharged to the outside is introduced into the working space portion 70 from the upper portion of the air passage portion 50, and the ultraviolet lamp 72 is turned on to work. The interior of the space 70 is sterilized, and the fluorescent lamp 71 is turned on to maintain a state in which the work can be performed in the workspace 70.

(2) liposuction

In this way, in order to perform a liposuction operation in a state where the working space part 70 is maintained in a sterile state, the suction connection tube 34 drawn out to the outside of the vacuum generating unit 63 is connected to the inhaler 20. Then, the air pump 62 is operated through the key input unit 3.

When the air pump 62 is operated, the vacuum generator 63 is maintained in a vacuum state through a valve. When the air pump 62 is in a desired vacuum state, a vacuum pressure is applied to the inhaler 20 through the connecting tube 33 so that the fat of the body part is reduced. Will be inhaled.

When the fat is sucked in a desired amount, the air pump 62 is stopped and the inhaler 20 is separated from the connecting tube 34.

(3) centrifugation

The inhaler 20 thus separated is inserted into the seating part 67 of the centrifuge in the clean bench 40 and the rotational speed, time, etc. are inputted through the key input part 3 or obtained from the auxiliary memory device 4. Using the data to drive the centrifuge motor 65, the rotor 66 rotates to rotate the seating portion 67 to centrifuge the fat.

In this centrifugation process, the separation layer appears due to the different specific gravity of fat, blood, body fluids, etc. At this time, only pure fat is left in the inhaler 20 and the rest is discarded.

(4) Local injection work

In this way, in order to inject the fat obtained in the state in which the working space portion 70 is maintained in a sterilized state into the body, the inhaler 20 into which the fat is injected is brought out to the outside of the pressure generating unit 64. After the connection is made to the desired body part, the air pump 62 is operated through the key input unit 3.

When the air pump 62 is operated, the air pressure is applied to the pressure generating unit 64 through the valve, and when the constant air pressure is maintained, the pressure is applied to the inhaler 20 through the connecting tube 33 to inject fat from the body part. Done.

When the fat is sucked in a desired amount to the site to inject fat, the operation of the air pump 62 is stopped and the inhaler 20 is removed from the connecting tube (33).

As described above, in the state where the clean bench 40 remains sterilized, the liposuction operation, the centrifugal separation operation, and the fat injection operation can be performed in a series of steps as described above.

And the connection and disconnection operation of the inhaler 20 and the connecting jig 30 will be described with reference to Figure 1, when the connection of the screw of the fastening plate 24 formed in the inhaler 20 and the head formed in the connecting jig 30 ( 35) screws are fixed by screw fit. At this time, in order to maintain an airtight state, the projecting piece 29 of the inhaler 20 is screwed in the fitted state in the engaging groove 32 of the connecting jig 30, and at this time, by the reinforcing action of the wing piece 31. This prevents accidents such as shocks or breaks when the screws are fitted.

The operation of separating the inhaler 20 and the connecting fixture 30 is performed in the reverse order to the above connecting operation.

The front part of the inhaler 20 is formed with a needle (not shown). When the vacuum pressure is applied through the packing 23 in a state in which the inhaler 20 and the connecting tool 30 are coupled, fat and Body fluids, such as blood, are introduced into the compression space 12, and the liquid is blocked by the packing in the same way as the syringe, so that the body fluid is filled in the compression space 12, and the cover is separated from the connecting jig 30. After fastening (27), only fat is extracted by centrifugation as described above.

As described above, the present invention performs liposuction, centrifugal separation, and lipoinjection operation in a sterilized state in a clean bench, so that various germs can be prevented during plastic surgery to minimize side effects after plastic surgery. There is a number.

In addition, the present invention serves as a leg of the power supply 61 and the air pump 62 clean bench 40, the motor 65 of the centrifuge is located in the lower center to maintain the center of gravity, the workspace The chamber 69 is located in the internal space constituting the power supply 61 of the unit 70 so that the area of the devices arranged inside the clean bench 40 is efficiently arranged and thus more compact than the clean bench of the same capacity. There is an effect that can be used practically.

In addition, by improving the structure of the existing inhaler 20 to connect the clean bench 40 and the inhaler 20 through the connecting jig and at the same time does not change the structure of the cylinder 10 of the inhaler 20 conventional inhaler It can be used as it is, it is effective to prevent the safety accident in advance by keeping the air tight to the connection structure between the inhaler and the jig and strong against impact.
