Description

Technical Field

[0001] This utility model relates to the field of blood oxygen saturation detection equipment, specifically to a wearable structure for a blood oxygen probe and a blood oxygen detection device. Background Technology

[0002] Blood oxygen testing generally refers to blood oxygen saturation testing, which measures the percentage of actual oxygen content in the blood relative to the maximum oxygen capacity the blood can carry. Blood oxygen saturation monitoring is an indicator of whether the body is hypoxic. Blood oxygen saturation represents the percentage of bound oxygen and hemoglobin in the blood relative to the total capacity of hemoglobin that can bind to oxygen. It indicates the concentration of oxygen in the blood and is an important physiological parameter of the respiratory and circulatory systems. This data can be monitored using a peripheral finger cot, a pulse oximeter, or by drawing arterial blood for blood gas analysis. A normal blood oxygen saturation value is above 98%. If the oxygen saturation is below 93%, the partial pressure of oxygen (POP) is usually below 60 mmHg, indicating hypoxia. Hypoxia requires timely treatment.

[0003] The first pulse oximeter was developed by Millikan in the 1940s. It monitors the ratio of oxygen-carrying hemoglobin to oxygen-depleting hemoglobin in the arteries. A typical pulse oximeter has two light-emitting diodes (LEDs). These LEDs are pointed towards the area of ​​the patient being tested—usually the fingertip or earlobe. One diode emits a beam of light at a wavelength of 660 nanometers, and the other emits at 905, 910, or 940 nanometers. Oxygen-carrying hemoglobin absorbs these two wavelengths very differently from oxygen-depleting hemoglobin. Using this property, the ratio of the two types of hemoglobin can be calculated. The test usually does not require drawing blood from the patient. Typical pulse oximeters can also display the patient's pulse. According to Beer-Lambert's law, the ratio R / IR should have a linear functional relationship with arterial oxygen saturation (SaO2). However, because biological tissues are complex optical systems with strong scattering, weak absorption, and anisotropy [2-4], they do not fully conform to the classical Beer-Lambert law. This makes it difficult to establish a mathematical model expressing the relationship between the relative change in absorbance of red and infrared light (R / IR value) and arterial oxygen saturation (SaO2). The correspondence between R / IR and SaO2 can only be determined experimentally, i.e., through calibration curves. Most pulse oximeter manufacturers obtain empirical calibration curves experimentally to complete pre-calibration before product shipment.

[0004] Blood oxygen saturation testing can be divided into non-invasive and invasive methods. Non-invasive testing, based on the red color of oxyhemoglobin and the blue-purple color of deoxyhemoglobin, measures blood oxygen saturation by detecting the absorption of light by capillaries in the nail bed. The advantages of non-invasive testing are that it does not cause trauma to the patient, is easily accepted by patients, and allows for continuous monitoring; therefore, it is commonly used for general hospitalized patients. However, non-invasive testing is an indirect method, and its error is generally larger than that of invasive testing. Invasive testing involves directly drawing arterial blood from the patient for analysis to measure blood oxygen saturation. The biggest advantage of this method is its high accuracy; therefore, it is commonly used for assessing the condition of patients with poor cardiopulmonary function or for monitoring blood oxygen during surgery under general anesthesia. However, because this method causes some discomfort to the patient and cannot provide continuous monitoring, it is generally not used for blood oxygen saturation testing in ordinary patients.

[0005] In the process of diagnosing and treating illnesses, especially when hospitals need to continuously monitor patients' vital signs, pulse oximeters are commonly used and used for extended periods. Pulse oximeter probes generally come in two types: clip-on and flexible. When using a pulse oximeter, the flexible probe is wrapped around the patient's finger, while the clip-on probe is clipped onto the patient's finger, typically the index, middle, or ring finger. If the index finger is unsuitable (e.g., due to injury, swelling, or poor blood circulation), other fingers can be used. Both flexible and clip-on probes present the following problems: 1. First, there is the issue of easy detachment, especially when blood oxygen saturation testing needs to be used for a long time. People's hands usually sweat, which affects the test and makes the fingers slip when they are sweaty. Both flexible probes and finger clips are more likely to fall off. 2. Especially when used with children, most children will resist it. The flexible probe can be easily detached by children, and the finger clip type will also be resisted by children because they are worried that it will hurt them. Utility Model Content

[0015] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages: This utility model relates to a wearable structure for a pulse oximeter probe. By mounting the pulse oximeter probe onto a flexible wrapping element and connecting the flexible wrapping element to a sleeve, the sleeve can be worn on the hand when pulse oximetry is needed.

[0017] The wearable structure of this novel pulse oximeter probe connects the finger clip component to the sleeve body, making the finger clip component less likely to fall off during use. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0022] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure. Example 1

[0023] The pulse oximeter probe wearable structure includes a sleeve 1. Figure 1 and Figure 2 The specific structure of the sleeve 1 is shown from different angles. The sleeve 1 is preferably a glove structure, and Figure 2 This demonstrates that the front end of the glove 1, specifically the front end of at least one finger, is cut off, allowing the hand to remain exposed when inside the glove 1; as shown... Figure 2 As shown, the sleeve 1 has at least one through hole 2, and the sleeve 1 is at least partially provided with a first adhesive rough surface 3 for fixed connection; it also includes a flexible winding member 4, which is at least partially connected to the sleeve 1, such as... Figure 2 and Figure 4 As shown, the flexible winding member 4 has a probe body 5 fixedly connected to it, and the probe body 5 is connected to a wire 8. Figure 3 , Figure 4 and Figure 7 The flexible winding member 4 is shown to have a second adhesive rough surface 6 fixedly connected to its outer surface; the flexible winding member 4 has an adhesive hook surface 7 fixedly connected to its end; that is, as shown in the image. Figure 3 and Figure 4 As shown, the adhesive hook surface 7 is the part of the flexible winding component 4 that is attached to the second adhesive rough surface 6 below it; the adhesive hook surface 7 is located on the inner surface of the flexible winding component 4. Figures 1 to 4 The diagram shows that the adhesive hook surface 7 at least partially wraps around both the first adhesive rough surface 3 and the second adhesive rough surface 6, and is detachably connected to both. The first adhesive rough surface 3, the second adhesive rough surface 6, and the adhesive hook surface 7 are Velcro; that is, the first adhesive rough surface 3 and the second adhesive rough surface 6 are the rough surfaces of Velcro, and the adhesive hook surface 7 is the hook surface of Velcro. Figure 5 and Figure 6 The image shows the effect of wearing the blood oxygen wearable structure of this utility model on a person's hand. Figure 5 and Figure 6 The images show a person's index finger inside the flexible winding component 4.

[0024] This utility model relates to a wearable structure for a pulse oximeter probe. By mounting the pulse oximeter probe onto a flexible wrapping element 4 and connecting the flexible wrapping element 4 to a sleeve 1, the sleeve 1 can be worn on the hand when pulse oximeter detection is needed. Because the flexible wrapping element 4 and the sleeve 1 are connected, the probe will not easily fall off even after prolonged wear, whether the hands are sweaty or the wearer is asleep. Furthermore, since the sleeve 1 is glove-shaped, children are less likely to resist wearing it due to fear.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 7 As shown, the end of the flexible winding member 4 has a widened portion 9, wherein... Figure 3 , Figure 4 and Figure 7 The widened component 9, which is formed by widening the side of the flexible winding component 4, can be seen intuitively. Figure 3 and Figure 4 The adhesive hook surface 7 is shown to be simultaneously distributed on the flexible winding member 4 and the widened portion 9. The widened portion 9 and the first adhesive rough surface 3 are at least partially overlapping.

[0026] The wearable structure of the pulse oxygen probe of this utility model, by setting the widened component 9 on the flexible winding member 4, allows the adhesive hook surface 7 to easily connect the first adhesive rough surface 3 and the second adhesive rough surface 6 at the same time, so that the flexible winding member 4 and the sleeve body 1 are more secure during application, and the flexible winding member 4 will not or is less likely to fall off.

[0027] In this embodiment 1, the positions of the first adhesive rough surface 3 and the second adhesive rough surface 6 can be interchanged with the adhesive hook surface 7. Example 2

[0028] like Figure 8 As shown, this embodiment 2 adopts all the schemes of embodiment 1. The difference is that the flexible winding member 4 is deleted, the finger clip member 10 is added, and the adhesive hook surface 7 and the probe body 5 are disposed on the finger clip member 10; at the same time, the adhesive hook surface 7 is detachably connected to the first adhesive rough surface 3.

[0029] like Figure 8 As shown, it includes a flexible connector 11, one end of which is fixedly connected to the finger clip component 10, and the adhesive hook is fixedly connected to the other end of the flexible connector 11.

[0030] The wearable structure of the pulse oximeter probe of this utility model connects the finger clip component 10 to the sleeve body 1, making the finger clip component 10 less likely to fall off during use. Example 3

[0031] This utility model relates to a blood oxygen detection device. The device as a whole adopts existing equipment, so the similarities with existing equipment will not be repeated. The difference is that the probe adopts the blood oxygen probe wearable structure described in either Example 1 or Example 2.
