Medical devices for treatment using sound pressure include a massage device using a vacuum, a lipolysis device for sucking the patient's skin using a vacuum and for dissolving the fat by irradiating ultrasonic waves to the suctioned area, a suction device for sucking the skin, Devices.

Medical devices that achieve therapeutic effects using conventional negative pressure treat the patient's skin by suctioning air inside the cup adhered to the patient's skin by maintaining the vacuum state by operating a pump to provide sound pressure.

That is, the medical instrument for medical treatment using the conventional sound pressure has a therapeutic effect while maintaining a vacuum state for a predetermined time in a state where the vacuum cup is fixed to the skin of the patient.

The medical device for medical treatment using the conventional pneumatic pressure has a problem that the therapeutic effect is limited because only the pneumatic pressure is provided in the state where the vacuum cup is attached to the patient's skin and the pneumatic pressure is obtained at the position where the vacuum cup is fixed.

Particularly, the medical device for medical treatment using the conventional pneumatic pressure has a problem in that a large number of vacuum cups must be adsorbed when the treatment portion is wide.

Also, in the medical device for medical treatment using the conventional pneumatic pressure, when the vacuum cup is moved forcibly while the negative pressure is applied, a wound caused by so-called "sweating" often occurs in the skin of the patient.

In addition, the medical instrument for medical treatment using conventional sound pressure does not include a separate structure for introducing air into the vacuum cup when the vacuum cup is removed from the patient's skin after treatment. Therefore, in a state where negative pressure is applied to the vacuum cup after treatment, the vacuum cup is forcibly separated from the patient's skin by the force of the operator, so that unnecessary pain is frequently given to the patient.
