Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a soft finger-cot blood oxygen probe structure. Background Technology

[0002] Blood oxygen saturation: The percentage of oxygenated hemoglobin (HbO2) in the blood that is bound to oxygen out of the total amount of hemoglobin (Hb) that can bind to oxygen. It is the concentration of oxygen in the blood and is an important physiological parameter of human respiratory and circulatory systems.

[0003] A blood oxygen saturation probe is an instrument used to measure the oxygen concentration in human blood. The probe typically consists of a light-emitting diode and a receiving diode. Timely monitoring of blood oxygen levels is crucial during surgical procedures or in the care of critically ill patients.

[0004] The existing soft finger cot pulse oximeter probes use TPU as the cable sheath and silicone as the soft finger cot. Currently, the industry uses instant adhesive to bond the cable sheath to the soft finger cot. However, the instant adhesive is brittle after curing, and the silicone soft finger cot is soft, so it will deform during use, causing the instant adhesive to fail. Moreover, customers may inadvertently pull the cable during use. Because the holding force between the cable and the probe soft finger cot is insufficient, pulling the cable will cause it to pull, resulting in stress on the internal red / orange core wire and eventually breakage, causing poor electrical performance of the product. Utility Model Content

[0005] To address the problem of insufficient holding force between the cable and the soft finger sleeve in existing technologies, this invention provides a soft finger sleeve blood oxygen probe structure that provides a more reliable connection between the cable and the soft finger sleeve.

[0006] This utility model provides a soft finger cot pulse oximeter structure, including a soft finger cot, a cable, and a flange copper ring. The soft finger cot has a finger receiving cavity, a first sensor mounting groove at the upper end of the finger receiving cavity, a second sensor mounting groove at the lower end of the finger receiving cavity, and a first wire hole at the upper end of the finger receiving cavity that communicates with the first sensor mounting groove. One end of the cable passes through the first wire hole and is inserted into the flange copper ring. The flange copper ring includes a polygonal sleeve and a flange plate located around one end of the polygonal sleeve. The polygonal sleeve is pressed and fixed to the outer end of the cable sheath, and the flange plate is placed in the first sensor mounting groove and fits against the periphery of the first wire hole.

[0007] As a further improvement of this utility model, an adhesive layer is provided between the cable and the flange copper ring.

[0008] As a further improvement of this utility model, the flange is provided with folded edge structures at both the upper and lower ends.

[0009] As a further improvement of this utility model, the soft fingertip blood oxygen probe structure also includes a sensor assembly electrically connected to the cable, the sensor assembly including a first sensor assembly installed in the first sensor mounting slot and a second sensor assembly installed in the second sensor mounting slot.

[0010] As a further improvement of this utility model, the first sensor assembly includes a first fixing base and a light-emitting tube installed in the first fixing base and communicating with the finger receiving cavity, and the second sensor assembly includes a second fixing base and a receiving tube installed in the second fixing base and communicating with the finger receiving cavity, wherein the light-emitting tube and the receiving tube are arranged opposite to each other.

[0011] As a further improvement of this utility model, a first cover plate is provided on the outside of the first sensor mounting slot, and a second cover plate is provided on the outside of the second sensor mounting slot.

[0012] As a further improvement of this utility model, a second threading hole is also provided in the side wall of the soft finger sleeve located on the side of the finger receiving cavity for connecting the first sensor mounting slot and the second sensor mounting slot.

[0013] As a further improvement of this utility model, the cable includes a first wire harness electrically connected to the light-emitting tube and a second wire harness electrically connected to the receiving tube. The second wire harness passes through the second wire hole from the first sensor mounting slot and is then electrically connected to the receiving tube.

[0020] like Figures 1 to 4 As shown, this utility model discloses a soft finger cot pulse oximeter structure, including a soft finger cot 1, a cable 2, and a flange copper ring 3. The soft finger cot 1 has a finger receiving cavity 4, a first sensor mounting groove 11 located at the upper end of the finger receiving cavity 4, a second sensor mounting groove located at the lower end of the finger receiving cavity 4, and a first wire hole 12 located at the upper end of the finger receiving cavity 4 and communicating with the first sensor mounting groove 11. The soft finger cot 1 is a silicone soft finger cot. One end of the cable 2 passes through the first wire hole 12 and is inserted into the flange copper ring 3. The flange copper ring 3 includes a polygonal sleeve 13 and a flange 14 located around one end of the polygonal sleeve 13. The polygonal sleeve 13 is pressed and fixed to the outer end of the cable 2. The flange 14 is placed in the first sensor mounting groove 11 and fits against the periphery of the first wire hole 12.

[0021] By setting the flange copper ring 3, the cable 2 and the soft finger sleeve 1 can be stably connected together. Even if the cable 2 is pulled, it will not come out of the soft finger sleeve 1, making the connection more reliable.

[0022] In this invention, an adhesive layer is provided between the cable 2 and the flange copper ring 3 to strengthen the stable connection between the flange copper ring 3 and the cable 2.

[0023] In this utility model, the flange 14 is provided with folded edge structures 15 at its upper and lower ends, so that it fits against the cover plate at the bottom and top of the first sensor mounting groove 11, ensuring that the cable 2 will not rotate at will, thereby ensuring the connection stability of its wire core.

The second wire harness passes through the second wire hole from the first sensor mounting slot 11 and is electrically connected to the receiving tube 8.

[0027] During assembly, first, pass the cable 2 with the repaired core wire through the first through hole 12 of the soft finger sleeve 1 and through the flange copper ring 3. Then, press the flange copper ring 3 onto the end of the cable 2 and apply glue to form an adhesive layer to ensure a more secure fixation. Next, fix the light-emitting tube 5 and the receiving tube 8 onto the first fixing seat 6 and the second fixing seat 9, respectively. Solder the core wire of the first wire harness to the pin of the light-emitting tube 5. After passing through the second through hole, the core wire of the second wire harness is soldered to the pin of the receiving tube 8. Apply AB glue (epoxy resin) to the soldered pins of the light-emitting tube 5 or the receiving tube 8 and cure them. Apply transparent silicone to the first fixing seat 6 and the second fixing seat 9 in the first sensor mounting slot 11 and the second sensor mounting slot to fix them. Finally, attach the first cover plate 7 and the second cover plate 10. The entire soft finger sleeve blood oxygen probe is now assembled.

[0028] This invention increases the tensile and torsional strength of the cable 2 by setting a flange copper ring 3, avoiding the risk of core wire breakage due to stress, improving the tensile strength of the product, reducing the cost of use, and ensuring signal stability and accuracy.
