## Abstract

An ultrasonic therapy patch used inside a human body, including a biomaterial bottom layer film and a biomaterial surface layer film laminated to each other, and a micro ultrasonic vibration module wrapped between the biomaterial bottom layer film and the biomaterial surface layer film. The ultrasonic therapy patch can be used safely inside the human body due to the biomaterials which it is made of, so that a site to be treated is directly covered by the patch and receives ultrasonic waves therapy directly from the patch.

## Claims

### Claim 1

An ultrasonic therapy patch, comprising a biomaterial bottom layer film and a
biomaterial surface layer film laminated to each other except for an area between the biomaterial bottom layer film and the biomaterial surface layer film in which a micro ultrasonic vibration module is provided between the biomaterial bottom layer film and the biomaterial surface layer film;
the micro ultrasonic vibration module comprises a housing and a housing cover assembled to each other, wherein an accommodating cavity is defined between an enclosure formed by the housing and the housing cover; the micro ultrasonic vibration module also comprises an ultrasonic vibration assembly and a driving control assembly, both disposed in the accommodating cavity;
the ultrasonic vibration assembly comprises a slidable block, resilient tabs disposed at two ends of the slidable block respectively, and at least one driving coil; at least one permanent magnet block is provided on the slidable block; the resilient tabs provides buffering and bouncing functions against the slidable block as the slidable block slides; said at least one driving coil cooperates with said at least one permanent magnet block to generate a magnetic driving effect;
the driving control assembly comprises a circuit board on which a wireless communication module is disposed, and a battery and a wireless charging coil which are electrically connected to the circuit board; said at least one driving coil is electrically connected to the circuit board to drive the ultrasonic vibration assembly to work.

### Claim 2 (depends on 1)

The ultrasonic therapy patch of claim 1, wherein the accommodating cavity is provided with a partition plate which partitions the accommodating cavity into a first working chamber and a second working chamber; the ultrasonic vibration assembly is disposed in the first working chamber, and the driving control assembly is disposed in the second working chamber.

### Claim 3 (depends on 2)

The ultrasonic therapy patch of claim 2, wherein the second working chamber is stacked on the first working chamber.

### Claim 4 (depends on 3)

The ultrasonic therapy patch of claim 3, wherein said at least one driving coil is disposed on the partition plate, and the slidable block is disposed on the housing cover.

### Claim 5 (depends on 1)

The ultrasonic therapy patch of claim 1, wherein sensors electrically connected to the circuit board are further disposed at two ends of the housing respectively.

### Claim 6 (depends on 1)

The ultrasonic therapy patch of claim 1, wherein transitional inclined planes are provided on peripheral sides of the housing.

### Claim 7 (depends on 1)

The ultrasonic therapy patch of claim 1, wherein each of the biomaterial bottom layer film and the biomaterial surface layer film is provided with a plurality of air-permeable through holes.

### Claim 8 (depends on 1)

The ultrasonic therapy patch of claim 1, wherein an adhesive layer is disposed on a bottom surface of the biomaterial bottom layer film, and a release paper is disposed on a bottom surface of the adhesive layer.
