Host 100 is disposed between proximal skin surface 321 and distal skin surface 322. As shown in fig. 2 and 3, the connecting member 300 is provided with a first engaging lug 311 and a second engaging lug 312, the first engaging lug 311 is disposed between the first side surface 331 and the skin proximal surface 321, and the second engaging lug 312 is disposed between the second side surface 332 and the skin proximal surface 321. The first coupling ear 311 and the second coupling ear 312 are respectively provided with a coupling slot 340, and the strap 200 passes through the coupling slot 340 on the first coupling ear 311, then extends along the proximal surface 321, and passes through the coupling slot 340 on the second coupling ear 312. When the portable oximeter is worn on the child's wrist, strap 200 is isolated between the wrist skin and connector 300 so that connector 300 is not directly attached to the skin.

In one embodiment, the connecting member 300 may not be a ring structure, for example, the connecting member is an open structure with an opening and the distal surface 322 of the open structure is removed, and the first side 331 and the second side 322 are provided with card-shaped structures, through which the connecting member is connected to the host computer.

In one embodiment, the main body 100 may be made of plastic, the connecting member 300 may be made of rubber, and the strap 200 may be made of skin-friendly cloth. Since the skin of a child is generally sensitive, the attachment member 300 directly contacts the skin of the child, which is likely to cause skin allergy, and the skin is isolated from the attachment member 300 by the band 200, thereby reducing the irritation of the attachment member 300 to the skin.

In one embodiment, the host 100 includes a housing, which may be made of plastic, for example, the host 100 may be made of Polycarbonate (PC), which is an amorphous polymer with a nearly colorless glass state and has good optical properties, polycarbonate high molecular weight resin has high toughness, and the housing made of polycarbonate has high structural strength and light weight. For another example, the shell can also be made of acrylonitrile-butadiene-styrene copolymer (ABS for short), the ABS engineering plastic is opaque in ivory granules, and the product can be colored in various colors and has high glossiness. The housing made of ABS engineering plastic has not only a glossy appearance but also excellent impact resistance.

In one embodiment, the connecting member 300 is made of a silicone material or a silicone rubber material, which is soft, has certain elasticity and high wearing comfort, but the silicone material has certain adsorption capacity and certain irritation to human skin.

In one embodiment, the strap 200 is made of a skin-friendly material, such as skin-friendly cotton or cloth, which does not easily irritate the skin when directly contacting the skin. The strap 200 is made of a soft material and can be bent and deformed. In one embodiment, the strap 200 may be made of multiple layers of material, for example, several layers of different materials along the thickness of the strap 200, wherein at least the layer of the strap 200 adjacent to the skin is made of a skin-friendly material.

In one embodiment, as shown in fig. 1, the strap 200 is an elongated sheet-like structure, and the first coupling ear 311 and the second coupling ear 312 are both provided with a coupling groove 340, and in one embodiment, as shown in fig. 2, the coupling groove 340 is an elongated groove 340A.

The first engaging groove 210a and the second engaging groove 210b are oppositely disposed and respectively disposed on two long sides of the binding band 200; the third engaging groove 210c and the fourth engaging groove 210d are disposed oppositely and respectively disposed on two long sides of the binding band 200. The width of the strap 200 between the first engaging groove 210A and the second engaging groove 210b is slightly smaller than the length of the elongated groove 340A, the width of the strap 200 between the third engaging groove 210c and the fourth engaging groove 210d is slightly smaller than the length of the elongated groove 340A, and the width of the strap 200 at other portions is larger than the length of the elongated groove 340A. The strap 200 passes through the elongated slot 340A of the first engaging lug 311 to allow the first engaging groove 210A and the second engaging groove 210b to be engaged with the first engaging lug 311, and the strap 200 passes through the elongated slot 340A of the second engaging lug 312 to allow the third engaging groove 210c and the fourth engaging groove 210d to be engaged with the second engaging lug 312. The width of the band 200 at other portions is larger than the length of the elongated groove 340A, for example, the width of the band 200 at least at both side portions of the first and second catching grooves 210A and 210b in the length direction of the band 200 is larger than the length of the elongated groove 340A, and the width of the band 200 at least at both side portions of the third and fourth catching grooves 210c and 210d in the length direction of the band 200 is larger than the length of the elongated groove 340A.
