The pressure parameter of the boost device with pressure dominant regulation according to the present embodiment is adjusted by the display setting unit, and for facilitating understanding of the work flow of the boost device with pressure dominant regulation, the following description is further provided with reference to the accompanying drawings.

As shown in fig. 11, when the booster device for pressure-dominant adjustment performs injection, parameter setting and mode setting are performed by the display setting means. After the injector sucks fat to be injected, the injector is embedded on the booster, an injection key 15 on the booster is pressed, and the booster performs injection according to preset parameters. The injection pressure can be observed through the display setting unit in the injection process so as to monitor in real time and ensure the safety of the injection process. And when the injection is finished, taking out the empty syringe, and filling the empty syringe into a second syringe which sucks fat for continuing the injection until the injection is finished.

As shown in fig. 12, when the booster for pressure-dominant regulation performs suction, parameter setting and mode setting are performed by the display setting means. The empty injector is embedded on the booster, the suction key 16 on the booster is pressed, and the booster performs suction according to preset parameters. The injection pressure (negative pressure) can be observed through the display setting unit in the suction process so as to monitor in real time and ensure the safety of the suction process. And when the suction is finished, taking out the syringe, and filling a second branch empty syringe for continuing suction until the suction is finished.

It should be noted that the boosting device for pressure-dominated adjustment of the present application can be applied not only to the injection and suction of autologous fat, but also to other similar scenarios, such as the injection of tumescent liquid, etc.

Because the injection mode and the suction mode have three specific working conditions of an autonomous mode, a quantitative jog mode and a quantitative continuous mode, when the modes are set, not only injection or suction needs to be set, but also specific working conditions need to be set, and the working modes of setting each specific working condition in the embodiment are as follows:

when the booster operates in the autonomous mode, the injection button 15 or the suction button 16 is closed, the booster keeps in an injection or suction state, the injection button 15 or the suction button 16 is released, and the booster stops injection or suction. In the autonomous mode, the booster is operated or not depending on the state of the key.

In this embodiment, a key closed is to be understood as a key pressed, and a corresponding key released is to be understood as a pressed key released.

The booster operates in a fixed-volume inching mode, the injection button 15 or the suction button 16 is closed once, and the booster injects or sucks once at a set flow rate. In the quantitative inching mode, the booster detects that the key is pressed once, namely, the booster executes an action, and the set flow action is performed once regardless of the time length of the key.

The booster operates in a quantitative continuous mode with the injection button 15 or the aspiration button 16 closed once and the booster performs a predetermined injection or aspiration action once at a preset flow rate and time interval.

In the quantitative continuous mode, the booster detects that the key is pressed once, namely, executes one action, and the booster executes only one preset action no matter how long the key is pressed. It should be noted that the quantitative continuous mode is different from the quantitative jog mode in that one stroke of the quantitative jog mode is used as one injection or suction at a predetermined flow rate, and one stroke of the quantitative continuous mode is used as one injection or suction action performed at a predetermined flow rate and time interval, which means that there may be a plurality of injections or suctions in one stroke of the quantitative continuous mode, and the interval between the plurality of injections or suctions is a predetermined time interval.

The booster first includes a basic injection mode and a suction mode to accomplish a conventional injection and suction action; secondly, on injection mode and suction mode, included autonomic mode, ration electric mode and ration continuous mode again, this makes the boost can realize intelligent accurate work under the prerequisite of guaranteeing conventional function, has not only reduced user's work load, has still further promoted the intellectuality and the precision of injection or suction.

Therefore, when the display setting unit sets the relevant pressure parameters, the pressure parameters comprise a mode type and parameters corresponding to the mode type, wherein the mode type comprises an injection mode or a suction mode and is an autonomous mode, a quantitative electric mode or a quantitative continuous mode in the injection mode or the suction mode; the parameters corresponding to the mode type are parameters which need to be set for realizing the mode operation, and can be adjusted according to actual conditions. For example, the parameter required to be set in the quantitative electric mode is the flow rate of injection or suction; also, as the quantitative continuous mode, the parameters to be set are the time interval, the flow rate of injection or aspiration.

It should be noted that the same structure described in the present embodiment mainly emphasizes that the components are the same, and the installation position of the components is not limited.

In order to further save costs, the boost device with pressure-controlled main regulation described in the above embodiments may be modified to obtain a lower cost boost device with pressure-controlled main regulation. For example, a display setting unit in the booster device which removes the pressure dominant adjustment, and the pressure and mode are adjusted by a key on the booster.

For example, the main power switch 21 is set to be turned on and off by a long press, and the mode switching by a short press is performed, that is, the main power switch 21 is pressed once by a short press, that is, one mode is cyclically switched, and the mode is restored to the default mode after each time of turning on, so that the mode switching is performed. Meanwhile, the short-time pressing of the injection button 15 while the main power switch 21 is pressed is set as pressure increase, the short-time pressing of the suction button 16 while the main power switch 21 is pressed is set as pressure decrease, the increase and decrease of the pressure at each time are fixed in a stepping mode, and the pressure is restored to the default pressure after the power-on at each time.

It should be noted that the manner of adjusting the pressure parameter and the mode by pressing the key is only one manner provided in the present embodiment, and various changes may be made on the basis.
