The present invention relates to a centrifugal separator having a liposuction and infusion function, and more specifically, to a conventional centrifuge, an additional air pump, a valve, and a control unit capable of a vacuum and a press function are used to perform liposuction performed during self-fat transplantation. The present invention relates to a centrifuge having a liposuction and infusion function that enables a centrifugal separation and a lipoinjection process into a single device.

In general, there are implantation implantation and autologous liposuction in enlargement molding such as breast augmentation and facial shaping (nose, nasolabial fold, cheek, etc.). Implant insertion is easy to control in size and largely at once. While it is not safe and does not feel or feel good, autologous liposuction inhales excess fat such as your stomach or leg and re-injects it into relatively poor breasts, hips, or face, eliminating unnecessary fat Since the enlargement of one part is made together, the balance of the body is made and the self-fat is injected directly, so there is no resistance to foreign substances and there is an advantage that the texture or feel is good. However, in the case of autologous lipoinjection, the fat survival rate is extremely low as 20 ~ 50%, so it is not possible to obtain the size as desired. To obtain the desired size, two or three procedures are required, which requires a lot of time and money. There is a problem. Therefore, various attempts have been made to increase the fat survival rate, and clinical trials have shown that only the pure fat is filtered and injected to increase the survival rate. When the fat is inhaled, not only fat but also blood, body fluids, impurities, and the like are sucked out, and thus, a centrifuge can be used as a method for separating the pure fat.

As described above, autologous lipoinjection is mainly composed of liposuction, centrifugal separation, and lipoinjection process. Usually, liposuction uses suction to vacuum suction bottles to inhale fat, and centrifugal separation process to make pure fat is separate. Centrifuge is used. In order to inject the fat after the centrifugation process into the body transplantation site, it is common to inject directly by hand using a syringe.

Therefore, for autologous liposuction, a centrifuge is also required separately from the aspirator, which takes up a lot of operating room space, and the user has to deal with various devices and has to move around. Also, in the injection, the injection site is injected directly by hand using a syringe, so a strong resistance area such as the muscle layer is high, and it is difficult to continuously inject it at a constant pressure using the hand, which causes the implant area to be uneven. There is a problem.

In order to solve the above problems, by installing an air pump, a valve, and a control unit capable of vacuum and press functions in an existing centrifuge, a vacuum and press using a pneumatic component as well as a basic centrifugal separation function can be selectively performed. When the inhalation and infusion by hand, the operator has a lot of strength and pressure control is difficult to prevent the side effects of the inhalation or injection area of the body uneven, and can be performed quickly and conveniently during the autoinjection procedure It is an object of the present invention to provide a device that enables the process of liposuction, centrifugation, and lipoinjection to be integrated.

 However, even in the existing centrifuge, the air pump may be installed in order to reduce the frictional air force by making the chamber into a vacuum, but the object of the present invention is that the vacuum pump and the press function as components connected to the outside rather than using the air pump in the chamber vacuum It is characterized in that it is integrated with the basic centrifuge.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram according to the present invention, the apparatus includes centrifugal separators (1, 2, 3), drive means (4), control unit (5), power supply unit (6), case (7), The pump part 11 and 12 and the foot switch 31 are comprised.

The centrifuges 1, 2 and 3 constitute a conventional centrifuge and include a bucket 1, a rotor 2 and a chamber 3. The rotor 2 may be a swing rotor or an angle rotor with a rotary blade, and the bucket 1 may be mounted on one surface of the rotor 2 to fit one or more tubes or syringes, and the chamber 3 may be It is sufficient if the rotor 2 and the bucket 1 are spaces that can be safely accommodated when they rotate.

The driving means 4 is mounted to the lower part of the rotor 2 to rotate the rotor with the electric power supplied through the power supply unit 6. The drive means 4 is controlled by the controller 5.

When the rotor 2 in the chamber 3 rotates, a door 7a is installed above the chamber 3 to close and open the chamber 3 so that it can be sealed for safety, so that the tube or syringe can be centrifuged. The door 7a can be opened and mounted on the bucket 1, and the door 7a can be closed during the centrifugal operation.

The case 7b is coupled to one side so as to hinge the door 7a to support the whole, and forms a connector 21 on one side so as to be connected to the external component 22. The external component 22 is an external infection by air contact since the liposuction container of the closed-type fat transplantation system described in Patent Application No. 10-2003-0005029 enables liposuction and lipoinjection process as one container. Can be eliminated.

The pump parts 11 and 12 are composed of an air pump 11 and a valve 12, and the air pump 11 is a pump capable of vacuum and press and is connected to the case connector 21 and is located inside the case. The valve 12 is a valve that is connected between the air pump 11 and the case connector 21 to be automatically opened and closed by electricity, so that the vacuum and the press are applied to an external component 22 connected to the case connector 21. It can be done selectively. The pump parts 11 and 12 are also controlled by the control part 5.

2 is a view showing a flow for preparing the operation of the device during the initial power supply of the present invention, when the power supply unit 6 supplies power to the device and turns on the device of the pump unit (11, 12) The valve 12 is operated in unison for 10 seconds. This is a process of drawing out any air that may remain in the line between the case connector 21 and the air pump 11, to prevent inhalation and injection by unintentional pressure so as to enable safe operation. to be.

The time flows at intervals of 1 second and is configured so that no operation is performed for 2 seconds to leave a minimum air removal time for the operation of the air pump 11. After 2 seconds, when the input for operation comes in, the controller 5 simultaneously closes the entire valve 12 in operation and records the input state at the same time, and goes to the 'ready' state shown in FIG. The corresponding air pump 11 and the valve 12 are operated to allow suction or injection. If there is no input for operation, the valve 12 is automatically closed after the operation for 10 seconds, and is ready for operation. The time of 10 seconds is sufficient for air removal and can be changed.

Liposuction and infusion, centrifugation can be performed with the device having the above configuration, and can be operated using the footswitch 31 for more convenient operation during liposuction and fat injection. Operation of the air pump and the valve according to the vacuum and press function and the operation of the device by the footswitch operation will be described with reference to Figures 3 and 4 as follows. The direction of the arrow in FIG. 3 means the flow of air.

Foot switch 1 31 a is for vacuum, foot switch 2 31 b is for low pressure press, and foot switch 3 31 c is for high pressure press. The quantity of the foot switch 31 may vary depending on the function.

Inserting the cannula through the 2-5mm incision of the area to be fat-ejected for liposuction, and pressing the foot switch 1 (31a) to apply a vacuum to the external component 22 connected to the cannula, the control unit 5 The valve 1 (12a), 5 (12e) is opened by the air pump 11 is operated. Through the above process, the air in the external component 22 moves to the valve No. 5 (12e), the air pump 11, the valve No. 1 (12a) to go out, and the cannula while the external component 22 is in a vacuum state. Liposuction is achieved through. When the foot switch 1 (31a) is stopped to end the suction, the valves 1 (12a), 5 (12e) and the air pump 11 that are in operation are stopped.

Fats inhaled through the above process are not only fats but also blood, body fluids and other impurities are inhaled. When injected directly into the chest, face or hips, most of the injected fats are inhaled to obtain the size or shape as desired. I can't. Therefore, various attempts have been made to increase the fat survival rate, and clinical trials have shown that only the pure fat is filtered and injected to increase the survival rate. The pure fat can be obtained through a centrifugation process, because the specific gravity of fat, blood, body fluids, etc. is different, so when centrifuged, the fat is divided into a blood layer and a fat layer. Therefore, the blood layer can be removed and only pure fat can be implanted in the human body.

After centrifugation, a cannula or needle is inserted into the body part to be injected for fat injection, and a press is applied to an external component 22 connected to the cannula or needle, the press being a pressure regulator 13 It can be adjusted to low pressure and high pressure or various pressures. The pressure regulator 13 is operated according to the flow of air, and maintains the set constant pressure. Therefore, it can be performed at a certain pressure during the fat injection procedure and can eliminate side effects of becoming rugged. In general, a low pressure press may be used where the resistance is low, such as a subcutaneous fat layer, and a high pressure press may be used when the resistance is strong, such as a muscle layer.

First, when the low pressure press foot switch 2 (31b) is pressed to inject fat into the normal subcutaneous fat layer, the valves 2 (12b) and 4 (12d) are opened by the controller 5 and the air pump 11 is operated. Through the above process, the outside air supplies air to the external component 22 through the valve 4 (12d), the air pump 11, the pressure regulator 13, the valve 2 (12b) to the external component 22 The fat inside is injected into the graft site via cannula or needle. When the foot switch 2 (31b) is stopped to complete the injection, the valves 2 (12b) and 4 (12d) and the air pump 11 which are in operation are stopped.

In addition, when the resistance is strong, such as the muscle layer, the low pressure press is not smoothly injected into the human implant site, press the high-pressure press footswitch 3 (31c). Then, valves 3 (12c) and 4 (12d) are opened by the controller 5 and the air pump 11 is operated. Through the above process, the outside air supplies air to the external component 22 through the valve 4 (12d), the air pump 11, the pressure regulator 13, and the valve 3 (12c) to the external component 22. The fat inside is injected into the graft site via cannula or needle. When the foot switch 3 (31c) is stopped to complete the injection, the valves 3 (12c) and 4 (12d), which are in operation, stop the operation of the air pump 11.

In the low pressure press and the high pressure press process, the speed controller 14 is installed on the press line between the air pump 11 and the case connector 21 to control the speed, and the speed controller 14 controls the flow of air. It can be used according to the master's degree of mastery or human treatment because it can control the moving speed of air when using the press.

When the suction and injection procedure is more than the intended pressure value (overpressure) in the pressure regulator 13 to automatically stop the air pump 11 and the valve 12 to produce the effect of stopping the operation of the foot switch 31 In the flow chart of the apparatus by the footswitch operation of FIG. 4, the 'yes' process of 'overpressure?' This serves as a safety device in case the pressure regulator 13 is in case of an abnormality.

In addition, when the suction and injection of the foot switch 1, 2, 3 (31) stops the operation of the valve 12 and the air pump 11 in operation, at the same time valves 1,2, 3, 4, 5 (12) This work in concert to remove the residual pressure in the external component 22 can prevent the process of sucking fat or injecting fat at an unintentional pressure when removing the cannula or needle in the human body. When the above process is performed, the process proceeds to the state '0' of FIG. 2, and the operation is performed in the same order as the state in which the device is turned on.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention adds an air pump, a valve, and a control unit to an existing centrifuge to give a vacuum and a press function to an external component connected through an external connector of the case together with a basic centrifugation function. Liposuction, centrifugation, and lipoinjection can be performed in one instrument. Therefore, it does not need space for installing a separate aspirator, and the parts are much simpler, so the device can be miniaturized, and the whole procedure of autologous lipoinjection can be performed with one device, allowing the operator to operate conveniently and quickly during surgery. This can reduce the operation time and the operator's effort.

In addition, pneumatic pressure is used to inject fat, so even if the resistance is strong, such as the muscle layer, it can be injected with less force, and the injection is made at a uniform pressure compared to when injecting by hand, thus eliminating the uneven side effect of fat graft. In addition, the speed controller can be adjusted quickly or slowly by additionally equipped with a speed controller, which can be selected and used according to the degree of mastery of the operator during the implantation process.
