Abstract: A treatment device for medical and/or cosmetic therapy includes a negative-pressure chamber receiving a lower half of a person's body. The negative-pressure chamber is designed as a tube and has an admission opening sealed off from the person's body by a closure element. A first part of a table is arranged in the interior of the negative-pressure chamber. A second part of the table is arranged outside the negative-pressure chamber. The first part and the second part are each guided longitudinally on a linear guide. The first part can be moved at least partially out of the negative-pressure chamber and the second part can be moved away from the admission opening. A synchronization between the first part and the second part allows the first and second parts to be moved at the same speed in the same direction.

Abstract: A handheld high frequency ultrasonic atomizing device for delivering drugs to whole respiratory tract comprising a shell with an air inlet and a lid with a spray nozzle. A drug cup with a piezoelectric transducer and a hood with a spray outlet are provided within the shell. The components of piezoelectric ceramic transducer are as follows (mass percentage): lead tetraoxide 63.3-68.3%, zirconium dioxide 14.2-15.3%, titanium dioxide 8.1-9.5%, strontium oxide 4.6-5.2%, iron sesquioxide 1.5-1.8%, stannic oxide 1.0-1.4%, manganese dioxide 0.3-1.1%, cerium sesquioxide 0.5-0.8%, columbium pentoxide 0.4-0.8% and zinc oxide 0.3-0.7%. This device is small in size, with low power consumption and lower cost, and is able to produce mist with small particle size. The device can efficiently deliver drug liquid into the whole respiratory tract, especially down to the lower respiratory tract and pulmonary alveoli through carrying drug molecules in mist particles.
