## Abstract

Disclosed is a sensor pad outer cover comprising a first surface layer and a second surface layer which together form an accommodating cavity configured to receive a sensor pad body of a medical sensor pad, the first surface layer further comprising a non-slip layer, wherein both the first and second surface layers are formed from at least one biodegradable material for reduced environmental pollution.

## Claims

### Claim 1

A sensor pad cover, comprising:
a first surface layer and a second surface layer which form an accommodating cavity configured to receive a sensor pad body,
the first surface layer including a non-slip top layer,
wherein both the first surface layer and the second surface layer are formed from at least one biodegradable material,
wherein the accommodating cavity is provided with an outward-extending exhaust port configured for passage of wiring,
wherein the exhaust port comprises a first exhaust hole and a second exhaust hole, and an inner diameter of the first exhaust hole is adapted to the wire, and the second exhaust hole is provided with a viscous film to form a one-way valve.

### Claim 2 (depends on 1)

The sensor pad cover of claim 1, wherein an edge of the first surface layer is fixedly connected with an edge of the second surface layer.

### Claim 3 (depends on 2)

The sensor pad cover of claim 2, wherein the edge of the first surface layer and the edge of the second surface layer are press-molded to form an arc-shaped transition at an edge position of the outer cover.

### Claim 4 (depends on 1)

The sensor pad cover of claim 1, wherein first surface layer and the second surface layer are formed from a same material.

### Claim 5 (depends on 1)

The sensor pad cover of claim 1, wherein the first surface layer and the second surface layer are formed from PBAT/PLA material.

### Claim 6 (depends on 1)

The sensor pad cover of claim 1, wherein the second exhaust hole comprises a first extension sheet and a second extension sheet,
wherein the first extension sheet is integrally formed with the first surface layer, and the second extension sheet is integrally formed with the second surface layer,
wherein a first end and a second end of the first extension sheet is fixedly connected to a first end and a second end of the second extension sheet, respectively.

### Claim 7 (depends on 1)

The sensor pad cover of claim 1, wherein the cover is configured to removably encase the sensor pad body, such that the cover is replaceable.

### Claim 8 (depends on 7)

The sensor pad cover of claim 7, wherein the sensor pad body comprises a first sensor pad layer, an intermediate layer, and a second sensor pad layer,
wherein least one side of the first and second sensor pad layers is provided with a conductive coating and the intermediate layer is sandwiched between the first and second sensor pad layers and fixedly connected to the first and second sensor pad layers, and
wherein the intermediate layer comprises an insulating material and a plurality of through holes,
wherein the through holes are configured to enable contact between the first and second sensor pad layers when the sensor pad body is housed within the sensor pad cover and the first and second sensor pad layers are pressed via force applied to the cover.

### Claim 9 (depends on 1)

The sensor pad cover of claim 1, wherein the cover is disposable and biodegradable.
