The application provides a sensor bandage support device can compromise the wearing travelling comfort when guaranteeing the compactness of sensor and skin laminating, has both guaranteed the stability that detects, has promoted again and has experienced the sense, obviously promotes holistic use and experiences the sense.

In the above embodiments, the shape of the mount 1 can be adjusted according to specific use needs, for example, according to the shape and size of the health monitoring sensor.

The binding bands 2 can be in a rope structure or a flat belt structure, the number of the binding bands 2 arranged on the mounting seat 1 can also be set in a targeted manner according to the wearing mode, and the binding bands 2 can be in an annular structure and comprise an annular breakable structure or a non-breakable elastic structure.

On the basis of the above-mentioned embodiment, the quantity of bandage 2 specifically is two or more, and bandage limit structure includes that bandage 2 can penetrate into the spacing passageway 110 that sets up, and the top of mount pad 1 is located to two spacing passageways 110 symmetries, and all corresponds in two spacing passageways 110 and is provided with bandage 2.

The limiting channel 110 is a structure capable of penetrating the binding band 2, the limiting channel 110 is arranged at the top of the mounting seat 1, the binding band 2 penetrates the limiting channel 110, and two ends of the binding band 2 are both positioned outside the limiting channel 110 and are connected and arranged at the other side to form the annular binding band 2.

The limiting channel 110 is disposed on the top of the mounting seat 1, so that the channel inlets 111 at two ends of the limiting channel 110 are necessarily located on the top of the mounting seat 1, which may be the top surface of the mounting seat 1, or the circumferential position of the top.

It should be noted that the description of the two ends of band 2 does not limit band 2 to a breakable structure, but is for convenience of description of the manner in which the portion of band 2 located outside of position-limiting channel 110 is provided.

It should be noted that the number of the straps 2 in this embodiment may be two, one strap 2 is disposed in each of the two position-limiting passages 110, or the number of the straps 2 is more than two, so that at least two straps 2 are threaded into at least one position-limiting passage 110.

The limiting channel 110 is mainly used for forming a structure penetrating into the binding band 2, so that the binding band 2 can penetrate through the top position of the mounting seat 1, and in the process of extending to the two sides of the limiting channel 110 and extending to the wearing position, a pulling force applied to the mounting seat 1 to the wearing position is formed. The channel entrance 111 of the limiting channel 110 is therefore preferably arranged in the region of the top of the mounting socket 1 without projecting out of the plane of the top.

On the basis of the above embodiment, the limiting channels 110 are arc-shaped limiting channels, and the concave parts of the two arc-shaped limiting channels face to the center of the top of the mounting seat 1.

Referring to fig. 1 to 4, the inner wall of the limiting channel 110 has an arc structure or a C-shaped structure, and the arc structures of the two limiting channels 110 are both concave toward the center of the top of the mounting base 1, so that when the strap 2 disposed in the limiting channel 110 is pulled tight, the force applied by the strap 2 is concentrated toward the direction of the gathering of the two limiting channels 110, resulting in the strap 2 tightly fitting the inner wall of the limiting structure 110. The arcuate configuration of the inner wall helps to limit the direction of extension of strap 2 and enables the application of downward pressure through strap 2 to mount 1 and gathered toward the top center of mount 1 when strap 2 is tightened.

Preferably, the strap entrance portion 121 is located at the outer circumferential edge of the mounting seat, and the limiting passage 110 is a closed structure, i.e. the strap will not fall out of the limiting structure when the strap is under tension.

Alternatively, the limiting channel 110 may have other shapes.

Preferably, the strap 2 is an elastic strap structure, which is convenient for stretching and applying force during use.

On the basis of the above embodiment, the degree of curvature of the first inner side wall 112 near the center of the top part in the arc-shaped limiting channel is smaller than that of the second inner side wall 113 far away from the center of the top part;
