Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a multi-specification compatible blood oxygen saturation finger sensor. Background Technology

[0002] Blood oxygen saturation (SaO2) is the percentage of oxygen-bound oxyhemoglobin (HbO2) in the blood relative to the total available hemoglobin (Hb), representing the concentration of oxygen in the blood. It is a crucial physiological parameter for the respiratory and circulatory systems. Functional oxygen saturation, however, is the ratio of HbO2 concentration to the total HbO2 + Hb concentration, distinct from the percentage of oxyhemoglobin. Therefore, monitoring arterial blood oxygen saturation (SaO2) can estimate lung oxygenation and the oxygen-carrying capacity of hemoglobin. Normal human arterial blood oxygen saturation is 98%, and venous blood is 75%. Human metabolism is a biological oxidation process, and the oxygen required for metabolism enters the bloodstream through the respiratory system, combines with hemoglobin (Hb) in red blood cells to form oxyhemoglobin (HbO2), and is then transported to various tissues and cells throughout the body. The blood's ability to carry and transport oxygen is measured by blood oxygen saturation.

[0003] A pulse oximeter is an instrument used to monitor blood oxygen saturation. Blood oxygen saturation is often abbreviated as SaO2 or SpO2. It refers to the degree to which hemoglobin binds with oxygen at a given oxygen partial pressure, that is, the percentage of oxygen content and oxygen capacity. Arterial blood oxygen saturation is usually used.

[0004] In real-world monitoring devices come in different models and have different connection interfaces, making it impossible for all pulse oximetry finger sensors to be fully compatible when connecting cables. Therefore, a multi-specification compatible pulse oximetry finger sensor is needed to solve the problems existing in the current technology. Utility Model Content

A control button 6 is located at the front of the top of the clamping cover 1. The OLED display screen 5 is located at the bottom of the transparent plate 4, and the control button 6 is located directly below the OLED display screen 5.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a connecting post 7 is fixedly connected to the rear of the bottom end of the clamping cover 1. Mounting holes 8 are provided on the left and right sides of the connecting post 7. Springs 9 are installed inside the mounting holes 8. Clamping rods 10 are fixedly connected to the top of both sides of the springs 9. A blood oxygen saturation sensor 11 is provided at the front of the bottom end of the clamping cover 1.

[0023] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a placement platform 12 is provided at the top front of the clamping base 2. The top of the outer surface of the placement platform 12 is arc-shaped, and a light-sensitive port 13 is provided at the center of the top of the placement platform 12. The light-sensitive port 13 senses whether the finger is placed correctly. If the finger is misplaced and no data can be detected, the OLED display screen 5 will display a message reminding the user to re-clamp the finger.

[0024] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a rotating groove 14 is provided at the top rear of the clamping base 2. Snap rings 15 are fixedly connected to the left and right sides of the rotating groove 14. Snap holes 16 are provided on the inner side of the outer surface of the two snap rings 15. The connecting post 7 rotates within the rotating groove 14, and the snap rod 10 on the outer side of the spring 9 is snapped inside the snap hole 16.

[0025] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that a data connection cable 17 is fixedly connected to the bottom rear end of the outer surface of the clamping base 2. A connection thread 18 is provided at the top end of the outer surface of the data connection cable 17. A connection slot 19 is provided inside the top end of the data connection cable 17. A data connection post 20 is fixedly connected to the bottom end of the inner surface of the connection slot 19. A data connection hole 21 is provided at the top end of the data connection post 20.

A connecting ring 23 is fixedly connected to the top of the data transmission line 22. A data connection groove 24 is formed on the inner side of the connecting ring 23. A data connection block 25 is fixedly connected to the bottom of the inner surface of the data connection groove 24. A rotating connecting ring 26 is threadedly connected to the top of the outer surface of the data connection line 17. Several damping blocks 27 arranged in a rectangular array are fixedly connected to the outer surface of the rotating connecting ring 26. This allows the top of the data transmission line 22 to be aligned with the top of the data connection line 17, causing the connecting ring 23 to slide in. Within the connecting slot 19, the data connecting post 20 and the data connecting slot 24 engage with each other, and the data connecting block 25 and the data connecting hole 21 engage with each other.

Once the finger is correctly positioned, the user can activate the blood oxygen saturation sensor 11 by briefly pressing control button 6 to detect blood oxygen saturation. After a short wait, the data will be displayed on the OLED display 5. When it is necessary to perform specific analysis on the currently detected data, it is necessary to connect to the monitoring instrument. The top of the data transmission line 22 is aligned with the top of the data connection line 17, so that the connecting ring 23 slides into the connecting slot 19, so that the data connection post 20 and the data connection slot 24 are engaged with each other, and the data connection block 25 and the data connection hole 21 are engaged with each other. After the connection is completed, rotate the connecting ring 26 so that the rotating connecting ring 26 rotates forward and connects the data connection line 20 and the data transmission line 22 together through the connecting thread 18. The detected data is transmitted to the monitoring instrument for analysis through the data connection line 20 and the data transmission line 22.

[0028] As can be seen from the above working process: align the top of the data transmission line 22 with the top of the data connection line 17, allowing the connecting ring 23 to slide into the connecting slot 19, causing the data connection post 20 and the data connection slot 24 to engage with each other, and the data connection block 25 and the data connection hole 21 to engage with each other. After the connection is completed, rotate the connecting ring 26 to rotate it forward and connect the data connection line 20 and the data transmission line 22 together through the connecting thread 18. This connection method is more convenient and faster. When blood oxygen saturation detection is required, the device can be quickly connected to the monitoring instrument's wiring.
