Background
At present, a common monitor is equipped with a blood oxygen detection function, and a blood oxygen probe accessory is usually connected to the monitor to acquire human body signals. Blood oxygen probes are typically provided with two light emitting diodes that face the area of the patient to be measured, typically a fingertip or an earlobe. One diode delivers a beam with a wavelength of 660 nm and the other delivers a beam of 905, 910 or 940 nm, with the absorbance of oxygenated hemoglobin at these two wavelengths being very different from that without oxygen. Using this property, the ratio of the two haemoglobins can be calculated. The detection process usually does not need to draw blood from the patient, so the noninvasive blood oxygen detection is widely popularized and applied.
Conventional blood oxygen probes are classified as disposable and reusable. In the repetitive blood oxygen probe which is generally used for adults, in order to reduce the related interference influence between core wires, a shielding design is added between the core wires, so that the core wires are not damaged when being stressed and bent, and meanwhile, the stable acquisition of signals is ensured and the interference between the core wires is avoided.

The protection scope of the present application should be determined by the definitions of the appended claims.
Referring to fig. 1, fig. 1 is a schematic cross-sectional view of a blood oxygen cable 100 according to an embodiment of the present application. The blood oxygen cable 100 comprises a plurality of transmission core wires 140 and an outer shielding layer 160 integrally wrapping the plurality of transmission core wires 140, wherein at least a part of the outer sides of the transmission core wires 140 are individually wrapped with the inner shielding layer 130. Therefore, the transmission core wires 140 do not interfere with each other, and the layout of the transmission core wires 140 is not limited by the inner shielding layer 130, so that the blood oxygen cable 100 can be thinner, and the requirement of miniaturization of the device can be met.
It will be appreciated that in one embodiment, the inner shield layer 130 and the outer shield layer 160 are formed by a cable stranding process. Also, "inner" and "outer" of the inner shield layer 130 and the outer shield layer 160 are named only for distinguishing a relative positional relationship between the inner shield layer 130 and the outer shield layer 160, that is, the outer shield layer 160 is disposed outside the inner shield layer 130.
Specifically, the plurality of transmission core wires 140 include at least two light-emitting tube core wires 110 and two receiving tube core wires 120. In this embodiment, the outer side of each receiving core wire 120 is individually wrapped with an inner shield layer 130. It is understood that in other embodiments, the outer side of each light emitting tube core wire 110 is individually wrapped with the inner shield layer 130. Alternatively, in another embodiment, the outer side of each receiving core wire 120 and each light emitting core wire 110 is individually wrapped with the inner shielding layer 130. Therefore, the inner shielding layer 130 is separately disposed on the outer side of each receiving tube core wire 120 and/or each light-emitting tube core wire 110, so that electromagnetic shielding is performed between the receiving tube core wire 120 and the light-emitting tube core wire 110 through the inner shielding layer 130, and influence between the receiving tube core wire 120 and the light-emitting tube core wire 110 is reduced or avoided.
Specifically, in one embodiment, each light emitting core wire 110 includes a first conductor 1101 and a first insulating layer 1103 wrapping the first conductor 110. Each receiving core wire 120 includes a second conductor 1201 and a second insulating layer 1203 encasing the second conductor 1201. When the outer side of the light emitting tube core wire 110 is separately wrapped with the inner shielding layer 130, the inner shielding layer 130 is wrapped outside the first insulating layer 1103. When the outer side of the receiving core wire 120 is individually wrapped with the inner shielding layer 130, the inner shielding layer 130 is wrapped outside the second insulating layer 1203.
Specifically, the first conductor 1101 and the second conductor 1201 may be, but are not limited to, made of one of a conductive material and a conductive material containing conductive tensile fibers. It is understood that the first conductor 1101 and the second conductor 1201 may be made of the same material, or may be made of different materials. The conductive body may be, but not limited to, one or more of metal elements, alloys (copper alloys, aluminum alloys, and the like), composite metals, and other special-purpose conductive materials that do not have a main function of conductivity.
Specifically, the first insulating layer 1103 and the second insulating layer 1203 are made of an electrically insulating material by an extrusion process. Electrical insulating materials include, but are not limited to, oil impregnated paper, rubber, fiber, plastic, and the like.
Specifically, in one embodiment, the two light emitting core wires 110 and the two receiving core wires 120 are arranged around the axial center line of the blood oxygen cable 100. Further, in an embodiment, the two luminous tube core wires 110 and the two receiving tube core wires 120 are substantially equally spaced, that is, the two luminous tube core wires 110 and the two receiving tube core wires 120 are equally spaced around the axial center line of the blood oxygen cable 100. It is to be understood that, in an embodiment, when the two vessel core lines 110 and the two target receiving vessel core lines 140 are arranged circumferentially, the two vessel core lines 110 are disposed adjacently, and the two target receiving vessel core lines 140 are disposed adjacently. In another embodiment, when the two arc tube core wires 110 and the two target receiving tube core wires 140 are arranged in a surrounding manner, one target receiving tube core wire 140 is interposed between the two arc tube core wires 110, and one arc tube core wire 110 is interposed between the two target receiving tube core wires 140. Therefore, the two luminous tube core wires 110 and the two receiving tube core wires 140 are substantially symmetrical, so that the blood oxygen cable 100 is relatively balanced in force in any direction of the circumference thereof, and the blood oxygen cable 100 is not damaged due to bending in a certain direction.
Further, the two light emitting tube core wires 110 and the two receiving tube core wires 120 are twisted to form a cable twisted body. The outer shielding layer 160 wraps the cable strand to achieve electromagnetic shielding between the cable strand and the outside of the outer shielding layer 160.
Further, the blood oxygen cable 100 further comprises a filling body 190. The packing body 190 includes a plurality of packing strips 1901. Each filling strip 1901 fills in a corresponding concave void formed between the light emitting core wire 110 and the receiving core wire 120 arranged around the axial center line of the blood oxygen cable 100. The plurality of filler strips 1901, the two light emitting tube core wires 110 and the two receiving tube core wires 120 are twisted into the cable twisted body, so that the blood oxygen cable 100 has a cylindrical appearance.
Further, the blood oxygen cable 100 further comprises an isolation layer 180 disposed between the outer shielding layer 160 and the cable strand. Specifically, the isolation layer 180 is formed on the cable strand through a cable stranding process. The outer shield layer 160 is also formed on the isolation layer 180 through a cable stranding process. Thus, the outer shielding layer 160 and the cable stranded body are isolated from each other by the isolation layer 180, and direct contact between the two is avoided.
Further, the blood oxygen cable 100 further comprises a sheath layer 170. The sheath layer 170 wraps the outer shielding layer 160 to perform an electrical insulation protection function. Specifically, in one embodiment, the sheath layer 170 is made of an insulating material, such as white polyvinyl chloride, etc., through an extrusion process to provide electrical insulation protection.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an oximetry cable 100a according to another embodiment of the present application. Blood oxygen cable 100a is similar to blood oxygen cable 100, except that blood oxygen cable 100a further includes a whole cable tensile core 101. The whole tensile core 101 is arranged between the light emitting tube core wire 110 and the receiving tube core wire 120 which are arranged in a surrounding manner. Accordingly, the entire light emitting core wire 110, the receiving core wire 120, and the filling member 190 are twisted around the entire cable tensile core 101 to form the cable twisted body. Specifically, in one embodiment, the integral tensile core 101 is made of a tensile fiber material. It is understood that in other embodiments, the whole cable tensile core 101 may be made of other materials with higher tensile strength, and is not limited herein.
Further, in this embodiment, the receiving core wire 120 further includes a conductor tensile core 1205 disposed within the second conductor 1201. The conductor tensile core 1205 is made of a tensile fiber material. It is understood that in other embodiments, the light emitting vessel core wire 110 further comprises a conductive tensile core (not shown) disposed within the first conductor 1101, which is also made of a tensile fiber material.
It will be appreciated that in yet another embodiment, a blood oxygen cable is applied to the blood oxygen probe, the blood oxygen cable including at least one light emitting core wire 110, at least one receiving core wire 120, an outer shield 160 and an inner shield 130. The outer shielding layer 160 entirely covers the at least one light emitting tube core wire 110 and the at least one receiving tube core wire 120. The inner shielding layer 130 covers each of the at least one light-emitting tube core wire 110, and/or the inner shielding layer 130 covers each of the at least one receiving tube core wire 120.
Specifically, the at least one light emitting tube core wire 110 and the at least one receiving tube core wire 120 are twisted to form a cable twisted body, the outer shielding layer 160 wraps the cable twisted body, and the isolation layer is disposed between the cable twisted body and the outer shielding layer 160.
Specifically, each of the at least one light emitting core wire 110 includes a first conductor 1101 and a first insulating layer 1103 that wraps the first conductor 1101; and/or each of the at least one receiving core wire 120 includes a second conductor 1201 and a second insulating layer 1203 encasing the second conductor 1201. When the outer side of the light emitting tube core wire 110 is separately wrapped with the inner shielding layer 130, the inner shielding layer 130 is wrapped outside the first insulating layer 1103. When the outer side of the receiving pipe core line 120 is individually wrapped with the inner shielding layer 130, the inner shielding layer 130 is wrapped outside the second insulating layer 1203.
Referring to fig. 3, fig. 3 is a schematic view of a wearable blood oxygen detector 1000 according to an embodiment of the present application. Specifically, the wearable oximeter 1000 includes a main unit 200 fixed to a human body (e.g., a wrist of the human body). Referring to fig. 4 and 5, the host 200 has a connector holder 210 connected to the blood oxygenation cable 100. The wearable blood oxygen detector 1000 further comprises the blood oxygen cables 100 and 100 a. The first end of the blood oxygen cable 100 is connected to the blood oxygen probe 300, and the second end of the blood oxygen cable 100 is connected to the connector holder 210 of the host 200.

The light emitting tube 320 and the receiving tube 330 are accommodated in the probe body 310. The at least one light emitting tube core wire 110 and the at least one receiving tube core wire 120 in the blood oxygen cable 100 extend from the first end of the blood oxygen cable 100, and then penetrate through the probe body 310 to be electrically connected with the light emitting tube 320 and the receiving tube 330, respectively.
Furthermore, the inlet of the probe body 310 for the blood oxygen cable 100,100a to pass through is disposed facing the insertion port of the connector holder 210 on the main unit 200, so that the blood oxygen cable 100,100a does not wind around the side of the main unit 200 facing the human body, thereby reducing the cable winding of the wearable blood oxygen detector 1000 during wearing.
The blood oxygen probe 300 is provided with a cavity 340 for accommodating a finger. The light emitting tube 320 and the receiving tube 330 are symmetrically disposed on two sides of the cavity 340, and the at least one light emitting tube core wire 110 and the at least one receiving tube core wire 120 extending from the first end are embedded in the probe body 310.

Threading channel 350 has an opening 360, with opening 360 facing the first end of blood oxygenation cable 100. The at least one light emitting vessel core wire 110 extending from the first end is connected to the light emitting vessel 320 after passing through the threading passage 350 from the opening 360.

It is understood that in another embodiment, threading channel 350 is disposed adjacent to receiving tube 330.

Further, the wearable oximeter 1000 further includes an electrocardiograph/respiration measurement cable 220, an anti-defibrillation structure 230, and at least three electrode pad connectors 240.
