[0002] In certain medical situations, sensors need to be fixed to the human body and adhered to the skin to detect the patient's vital signs. For example, a blood oxygen saturation sensor is used to measure the body's blood oxygen level. This sensor determines the oxygen content in the blood by detecting the amount of infrared and red light absorbed by the skin (commonly used in the vital sign detection / monitoring of newborns and children). When measuring brain and regional oxygen saturation, the sensor (including the sensor and the base that fixes the sensor) needs to be fixed to the patient's forehead. Utility Model Content

[0003] In view of this, the present application provides a sensor fixing strap that can adjust the tightness to fix the sensor firmly and comfortably on the human body, preventing problems such as sensor dislocation or falling that affect measurement accuracy; at the same time, it can only fix the sensor on the human body, avoiding the problem of fixing the wires in the strap and affecting comfort.

[0004] The present application provides a sensor fixing strap, comprising a main strap, an elastic strap and a fixing strap;

[0005] The main belt has a first end and a second end along the length direction, and a mounting hole for the sensor to pass through is provided on the belt body;

[0006] One end of the fixing belt is connected to the main belt through the elastic belt, and the other end is provided with a connecting structure and is used to be detachably connected to the second end of the main belt.

[0007] In a possible embodiment, one end of the elastic band is connected to the main band, and the other end is connected to the fixing band, and at least partial band sections of the elastic band and the fixing band are located inside the main band.

[0009] In a possible embodiment, the main belt includes a first belt body and a second belt body that are stacked in a thickness direction.

[0010] In one possible embodiment, the first belt body is located inside the second belt body and is a raised cloth; the connecting structure on the fixing belt is a hook surface of Velcro, the hook surface of the Velcro is located on the outer side of the fixing belt and connected to the first belt body, or the first belt body is located inside the second belt body, and the second belt body is a raised cloth; the connecting structure on the fixing belt is a hook surface of Velcro, the hook surface of the Velcro is located on the inner side of the fixing belt and connected to the second belt body.

[0011] In a possible implementation manner, the fixing belt is further connected to the first end of the main belt and is movable relative to the first end of the main belt.

[0012] In a possible embodiment, the first end of the main belt is provided with two through-holes arranged along the length direction of the belt body, and the fixing belt passes through the first through-hole and exits from the second through-hole.

[0013] In a possible embodiment, the perforation is a through hole that passes through the main belt along the thickness direction; or, the main belt includes two stacked belt bodies along the thickness direction, and the perforation is provided on the inner belt body.

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] First, it should be noted that spatial terms, such as "inside" and "outside," are intended to refer to two opposing first and second sides of a device or component. The use of "inside" and "outside" here is to facilitate understanding by aligning with the orientation of the drawing, the position of the device / component in use, or common descriptions in daily life. When the orientation of the drawing changes, spatial terms should be interpreted accordingly. For example, if the device or component in the drawing is flipped, "inside" should be interpreted as "outside."

[0025] In the embodiment of the present application, the inner side of the belt refers to the side facing the human body, and the outer side refers to the side facing away from the human body. The inner side refers to the surface of the belt facing the human body, and the outer side refers to the surface of the belt facing away from the human body.

[0026] Please refer to the attached Figure 1-Figure 4 An embodiment of the present application provides a sensor fixing strap, comprising a main strap 10, an elastic strap 5, and a fixing strap 4. The main strap 10 has a first end and a second end along its length, and is provided with a mounting hole 2 for the sensor to pass through. One end of the fixing strap 4 is connected to the main strap 10 via the elastic strap 5, and the other end is provided with a connecting structure for detachably connecting to the second end of the main strap 10. The connecting structure can be a button, a tie cord, or a Velcro 6. In a preferred embodiment, the Velcro 6 is convenient, quick, and easy to operate compared to a tie cord. Compared to a button, the Velcro 6 is flatter. When the strap is tied to a person's body, especially when it needs to be tied to a patient's head, a strap with high flatness provides increased comfort.

[0027] When in use, the sensor passes through the mounting hole 2 and fits the human skin, and the wire connected to the sensor remains outside the strap. After the two ends of the strap are connected, only the sensor can be fixed on the human body. The strap has an elastic band 5 to adjust the tightness to adapt to the head circumference of different patients. It can firmly and comfortably fix the sensor, effectively preventing the sensor from being dislocated or falling off due to the patient moving due to the loose strap, which affects the measurement inaccurately, and can also avoid fixing the wire inside the strap to affect the comfort.

[0028] In a preferred embodiment, the mounting hole 2 is a strip-shaped hole, which can extend along the length direction of the main belt 10, that is, the length direction of the strip-shaped hole is consistent or basically consistent with the length direction of the main belt 10. The length of the mounting hole 2 is matched with the width of the sensor, and the width of the mounting hole 2 is matched with the thickness of the sensor. In this way, the size of the mounting hole 2 can be minimized to allow the sensor to pass through, and the mounting hole 2 can be prevented from being too wide or too long, affecting the stability of the sensor fixation, and preventing the sensor from falling out of the mounting hole 2 or tilting up and unable to fully contact the human body, thereby affecting the measurement accuracy.

[0029] The mounting hole 2 may be provided with one or, as shown in the figure, at least two mounting holes 2 are provided and arranged along the length direction of the main belt 10. In this way, at least two sensors can be fixed with the same strap to simultaneously monitor vital signs of at least two areas of the human body.

[0030] At the same time, since the sensor passes through the main belt 10 and is tied to the human body by the main belt 10, the opaque material of the main belt 10 can block the sensor. The smaller the mounting hole 2, the better the main belt 10 blocks the sensor. In this way, the interference of external ambient light on the sensor can be avoided, thereby improving the accuracy of brain and regional oxygen saturation measurement.

[0031] In the present application, the elastic band 5 is not directly connected to the second end of the main band 10. The connecting structure for connecting the two ends of the main band 10 is not provided on the elastic band 5 but on the fixing band 4 connected to the elastic band 5. Providing the connecting structure on the fixing band 4 which is not elastic (compared to the elastic band 5) helps to enhance the convenience and stability of providing the connecting structure on the band compared to providing it on the elastic elastic band 5. For example, the Velcro 6 is provided on the fixing band 4, and voltage fusion can be adopted (applying voltage to the Velcro 6 and the fixing band 4 to fuse the two). The Velcro 6 is connected to the fixing belt 4 in a flat and stable manner, while the Velcro 6 is set on the elastic belt 5, which can only be connected by sewing or gluing. The connection stability itself is not as good as voltage fusion, and when the elastic belt 5 is expanded by tension, the Velcro 6 will be torn, which will also affect the connection stability. At the same time, the sewing thread will protrude out of the belt body, making the surface of the belt body uneven, which is not only unsightly (when the strap is tied to the patient's head, aesthetics is also a factor that affects the range of use of the product), but also makes the patient feel uncomfortable under the tension of the slightly tight strap.

[0032] At the same time, the elastic band 5 is not connected to the second end of the main band 10 through the elastic band 5, and the elastic band 5 is arranged on the inner side of the main band 10 (the side of the main band 10 facing the human body), which has a structural basis for enhancing the aesthetics.

[0033] For example, Figure 3 As shown, one end of the elastic band 5 is connected to the main band 10 and the other end is connected to the fixing band 4. The elastic band 5 is located on the inner side of the main band 10. At least part of the fixing band 4, such as at least a section connected to the elastic band 5 and close to the elastic band 5, is located on the inner side of the main band 10 and is blocked by the main band 10.

[0034] In a preferred embodiment, if the connecting structure, such as a Velcro 6, is provided on the outer side of the fixing strap 4 (the side of the fixing strap 4 facing away from the human body) and is connected to the inner side of the main strap 10, then both the elastic band 5 and the fixing strap 4 can be located inside the main strap 10. When the strap is tied around the body, only the main strap 10 is exposed, thereby improving the aesthetics.

[0035] In some embodiments, the connecting structure on the fixing belt 4 may be the hook surface of the Velcro 6, and the fur surface of the Velcro 6 may be provided on the main belt 10, or either the inner side surface or the outer side surface of the main belt 10 is a raised surface, that is, the inner belt body and the outer belt body of the main belt 10 are both raised cloth (raised cloth refers to cloth with plush on the surface, such as nylon raised cloth), or the inner belt body or the outer belt body of the main belt 10 is raised cloth. In this way, it is possible to avoid providing the fur surface of the Velcro 6 on the main belt 10, which not only saves production steps and helps save costs, but also reduces the thickness of the connection, which helps to improve the comfort felt by the human body when the pillow presses on the connection when lying down.

[0036] The main belt 10 can be a single-layer belt, such as a raised fabric. Alternatively, in some embodiments, the main belt 10 includes a first belt body 1 and a second belt body 3 stacked in a thickness direction. In this case, the main belt 10 is a double-layer or multi-layer belt, which has high light-shielding properties and helps improve the light-shielding performance of the sensor.

[0037] The first and second straps 1 and 3 can both be made of fleece, or one can be fleece and the other of another material. For example, the first strap 1 can be located inside the second strap 3 and made of fleece; the connecting structure on the fixing strap 4 is the hook surface of Velcro 6, which is located on the outside of the fixing strap 4 and connected to the first strap 1. In this way, not only can the elastic band 5 and the fixing strap 4 be located inside the main strap 10, but the fleece surface of Velcro 6 is also unnecessary on the main strap 10. Alternatively, the second strap 3, located outside, can be made of fleece; the hook surface of Velcro is located on the inside of the fixing strap 4 and connected to the second strap 3.

[0038] The first and second straps 1 and 3 can be made of different materials. For example, the first strap 1 can be made of fleece, while the second strap 3, located outside the first strap 1, can be more water-resistant than the first strap 1. This improves the water resistance of the strap. For example, in some categories, the second strap 3 can be made of waterproof fabric, such as Oxford cloth.

[0039] If the entire elastic band 5 is located inside the main strap 10, the point where the elastic band 5 connects to the main strap 10 will be some distance from the first end of the main strap 10. Therefore, to prevent the first end of the main strap 10 from tilting, in some embodiments, the fixing band 4 is also connected to the first end of the main strap 10 and can move relative to the first end of the main strap 10, that is, it is movably connected to one end of the main strap 10. This not only secures the first end of the main strap 10 so that it fits snugly against the fixing band 4, ensuring the entire strap is flat, but also allows the fixing band 4 to be pulled relative to the first end of the main strap 10, without hindering the adjustment of the strap's tightness.

[0040] Specifically, a connecting buckle for the fixing belt 4 to pass through is provided on the main belt 10. For example, a rope is provided on the inner side of the first end of the main belt 10. The rope is provided along the width direction of the main belt 10, and both ends of the rope are connected to the main belt 10. In this way, a buckle hole for the fixing belt 4 to pass through is formed between the rope and the main belt 10.

[0041] Alternatively, the first end of the main belt 10 is provided with two perforations arranged along the length direction of the belt body, and the fixing belt 4 is passed through the first perforation and passed through the second perforation. The two perforations can form a connecting buckle.

[0042] The perforations can be through-holes extending through the thickness of the main strap 10; alternatively, the main strap 10 can include two laminated strap layers, such as a first strap 1 and a second strap 3, along the thickness direction, with the perforations provided on the inner strap layer, such as the first strap 1. In this manner, at the junction of the fixing strap 4 and the first end of the main strap 10, the fixing strap 4 is not visible outside the main strap 10, improving aesthetics. When the strap is tied to a person, the fixing strap 4 is not visible on the outer side of the main strap 10.

[0043] like Figure 4 As shown, in some embodiments, the first end of the strap body is connected to the fixing strap 4 via an elastic connecting strap 7. This arrangement prevents the fixing strap 4 from moving too far relative to the first end of the main strap 10 due to the retraction of the elastic strap 5 when the strap is loosened, potentially causing it to fall out of the connecting buckle at the first end of the main strap 10.
