Abstract
Description
Technical Field
[0001] This application relates to the field of blood oxygen saturation monitoring probe technology, specifically to a blood oxygen probe. Background Technology
[0002] Blood oxygen saturation refers to the percentage of blood oxygen content to blood oxygen capacity. It is an important physiological parameter of the respiratory and circulatory systems. In medical care, it is necessary to monitor the patient's blood oxygen saturation in order to monitor the patient's vital signs and provide doctors with accurate diagnostic data.
[0003] In the industry, pulse oximeter probes are used in conjunction with monitors to monitor patients' blood oxygen saturation. Inside the pulse oximeter probe, the light-emitting tube and the receiving tube are usually connected by wires. During product manufacturing and use, due to pulling and other reasons, the position of the light-emitting tube and the receiving tube are easily displaced along with the wire, and the connection is prone to breakage, ultimately leading to inaccurate test data. Utility Model Content
[0004] This application aims to provide a blood oxygen probe that avoids the problem of breakage at the connection points between the transmitting module and the receiving module and the flexible conductor during product use, thereby improving the accuracy of the test structure.
[0005] This application provides a blood oxygen probe, including:
[0006] A flexible conductor, with a transmitting electrical connection and a receiving electrical connection on its front side;
[0007] An optoelectronic component includes a transmitting module and a receiving module, wherein the transmitting module is electrically connected to the transmitting electrical connection portion and the receiving module is electrically connected to the receiving electrical connection portion;

The flexible reinforcement member is configured to at least partially surround the detection area, and the emission exposure hole and the receiving exposure hole face opposite sides of the detection area, respectively. The emission module is exposed through the emission exposure hole, and the receiving module is exposed through the receiving exposure hole.
[0009] A flexible binding member is fixedly connected to the flexible reinforcement member and is used to cooperate with the flexible reinforcement member to fix the detected part surrounded by it.
[0010] In some embodiments, a signal transmission wire is further included, one end of which is electrically connected to the transmitting electrical connection and the receiving electrical connection via the flexible conductor, and the other end of which is used to connect to a monitor.
[0011] In some embodiments, the flexible conductor further includes a signal output electrical connection portion, which extends to the outside of one side of the flexible reinforcement, and one end of the signal transmission wire is electrically connected to the signal output electrical connection portion.
[0012] In some embodiments, the flexible conductor further includes a folded portion that extends to the outside of the other side of the flexible conductor and is positioned opposite to the signal output electrical connection portion. The folded portion is folded toward the back of the flexible conductor and extends to the signal output electrical connection portion, and is fixed by the flexible reinforcement and the flexible binding member to enhance the structural strength of the signal output electrical connection portion.
[0013] In some embodiments,
[0014] The flexible reinforcement is provided with a first winding portion, which is used to wind and fix the folded portion and the signal output electrical connection portion.
[0015] And / or,
[0016] The flexible binding member is provided with a second winding portion, which is used to wrap around the first winding portion.
[0017] In some embodiments, the flexible reinforcement includes a flexible covering layer, the front side of which has a first adhesion region and a second adhesion region, the first winding portion protruding from the flexible covering layer, and the emission exposure hole and the receiving exposure hole both penetrating the first adhesion region; the front side of the flexible conductor is adhered to at least a portion of the first adhesion region, and the back side of the flexible conductor is adhered to at least a portion of the second adhesion region, wherein the first adhesion region and the second adhesion region are folded and bonded together.
[0018] In some embodiments, the flexible binding member has a fixing bonding area and a binding bonding area, the second winding portion protrudes from the flexible binding member, the fixing bonding area is bonded to the side of the flexible reinforcement opposite to the back of the flexible conductor, and the binding bonding area is used to bond to the flexible reinforcement when the flexible reinforcement is wrapped around the detection area.
[0019] In some embodiments, the flexible conductor includes a flexible insulating substrate and a flexible conductive line. The flexible conductive line is disposed on the front side of the flexible insulating substrate, and the transmitting electrical connection and the receiving electrical connection are respectively disposed at both ends of the flexible conductive line. The signal output electrical connection and the folded portion are disposed opposite to each other on the flexible insulating substrate.
[0020] In some embodiments, a release layer is further included, which is used to adhere to the flexible fastener and is peeled off before the flexible fastener is secured to the flexible reinforcement.

[0033] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0036] In related technologies, a pulse oximeter probe composed of a light-emitting diode (LED) and a receiving diode is connected by soldering wires and then connected to a monitor via a signal transmission wire. During use, the pulse oximeter probe is wrapped around the area to be tested (e.g., fingers, soles of feet) and secured with a strap. The LED emits specific wavelengths of red and infrared light towards the area being tested. Based on the different light absorption characteristics of oxyhemoglobin and hemoglobin in the blood, the two wavelengths of red and infrared light are transmitted through the tissue and then converted into corresponding electrical signals by the receiving diode. Furthermore, the absorption of signals by other components in the tissue (e.g., skin, bones, muscles, venous blood) is constant, while the absorption of signals by oxyhemoglobin and hemoglobin in arterial blood varies periodically with the pulse. The signals received by the receiving diode are processed to obtain measurements of blood oxygen saturation and pulse rate.
[0037] However, during the winding process, the wires are easily pulled, causing the positions of the light-emitting tube and the receiving tube to move with the wires. This can lead to situations where the receiving module has difficulty receiving the red and infrared light emitted by the transmitting module. Furthermore, the soldering points are prone to breakage during use, ultimately resulting in inaccurate monitoring data.
[0038] In the following embodiments, the transmitting tube and the receiving tube are the transmitting module and the receiving module, respectively.
[0039] To address the aforementioned issues, this application provides a pulse oximeter probe that connects the transmitting module and the receiving module via a flexible conductive structure. This prevents the transmitting and receiving modules from shifting during the process of the pulse oximeter probe being wrapped around the area being tested, reducing the operational difficulty for medical personnel and improving the accuracy of monitoring results.
[0040] See Figures 1-3 As shown, the pulse oximeter probe 100 provided in this embodiment includes a flexible conductor 10, a photoelectric component 20, a flexible reinforcing member 30, and a flexible binding member 40.
[0041] The flexible conductor 10 has a plate-like or near-plate-like structure with a front and a back surface. The front surface faces the user during use, while the back surface is opposite to the front. This flexible conductor 10 is flexible and can be bent and rolled without affecting its structural performance. Figure 3 As shown, a transmitting electrical connection portion 111 and a receiving electrical connection portion 112 are provided on the front side of the flexible conductor 10.
[0042] The optoelectronic component 20 includes a transmitting module 21 and a receiving module 22. The transmitting module 21 is electrically connected to the transmitting electrical connection part 111, and the receiving module 22 is electrically connected to the receiving electrical connection part 112. In a specific embodiment, the transmitting module 21 is connected to the transmitting electrical connection part 111 by welding, and the receiving module 22 is connected to the receiving electrical connection part 112 by welding. The flexible conductor 10 can connect the transmitting module 21 and the receiving module 22 to a power source to provide the electrical energy required for operation to the transmitting module 21 and the receiving module 22.
[0043] The connection between the transmitting module 21 and the transmitting electrical connection part 111, and between the receiving module 22 and the receiving electrical connection part 112, is equivalent to a surface contact connection. Compared with the connection through wires in related technologies, the connection strength is higher and the connection part is less likely to break.
[0044] The flexible reinforcement 30 is fixed at least to the front side of the flexible conductor 10. In some embodiments, the flexible reinforcement 30 can be fixed to both the front and back sides of the flexible conductor 10 to enhance the structural strength of the flexible conductor 10. The flexible reinforcement 30 has a transmitting exposure hole 311 and a receiving exposure hole 312. The flexible reinforcement 30 is configured to at least partially surround the detected part, with the transmitting exposure hole 311 and the receiving exposure hole 312 facing opposite sides of the detected part, respectively. The transmitting module 21 is exposed through the transmitting exposure hole 311, and the receiving module 22 is exposed through the receiving exposure hole 312.
[0045] The detection site can be a patient's finger. After at least a portion of the flexible reinforcing member 30, which is fixed to the front of the flexible conductor 10, is wrapped around the detection site, the transmitting module 21 and the receiving module 22 face opposite sides of the detection site, with the flexible reinforcing member 30 covering at least a portion of the detection site. The transmitting module 21 emits detection light towards the detection site, while the receiving module 22 receives the detection light after it has passed through the detection site. The detection light emitted by the transmitting module 21 is red and infrared light of specific wavelengths, which changes periodically with the pulse according to the different light absorption characteristics of oxyhemoglobin and hemoglobin in the blood. The receiving module 22 receives the red and infrared light that has passed through and been absorbed by oxyhemoglobin and hemoglobin in the blood, converts it into corresponding electrical signals, and obtains the measurement data of blood oxygen saturation and pulse rate by processing these electrical signals.
[0046] The flexible binding member 40 is fixedly connected to the flexible reinforcing member 30. The flexible binding member 40 is used to cooperate with the flexible reinforcing member 30 to fix the detection part surrounded by it.
[0047] In some embodiments, the flexible binding member 40 can be fixedly connected to the flexible reinforcing member 30 by means of bonding, and at the same time, the testing part surrounded by the flexible reinforcing member 30 can be fixed by bonding to prevent the flexible reinforcing member 30 from loosening.
[0048] In this application, the transmitting module 21 and the receiving module 22 are electrically connected to the transmitting electrical connection portion 111 and the receiving electrical connection portion 112 of the flexible conductor 10, respectively. The contact area between the transmitting module 21 and the receiving module 22 and the flexible conductor 10 is larger. With this configuration, during the product manufacturing process and after the flexible reinforcing member 30 surrounds the part to be tested and is fixed by the flexible binding member 40, the transmitting module 21 and the receiving module 22 are less likely to shift due to pulling the flexible conductor 10. In addition, the connection between the transmitting module 21 and the receiving module 22 and the flexible conductor 10 is less likely to break, thereby improving the accuracy of the test results.
[0049] The pulse oximeter probe 100 provided in this application can be connected to a monitor to display the test results in real time. For details, please refer to [link to relevant documentation]. Figure 1 and Figure 2 As shown, the pulse oximeter probe 100 provided in this application also includes a signal transmission wire 50. One end of the signal transmission wire 50 is electrically connected to the transmitting electrical connection part 111 and the receiving electrical connection part 112 through a flexible conductor 10. The other end of the signal transmission wire 50 is used to connect to a monitor. The detection results obtained by the pulse oximeter probe 100 can be transmitted to the monitor through the signal transmission wire 50 for real-time display, so that medical staff can observe the results.
[0050] In some embodiments, the other end of the signal transmission wire 50 is provided with a plug 51, which is connected to the monitor in a plug-in manner to facilitate operation by medical staff.
[0051] like Figure 1 and Figure 3 As shown, the flexible conductor 10 is also provided with a signal output electrical connection part 113, which extends to the outside of one side of the flexible reinforcement 10. One end of the signal transmission wire 50 is electrically connected to the signal output electrical connection part 113 by welding.
[0052] Because the signal output electrical connection portion 113 is formed by extending to the outside of one side of the flexible reinforcement 10, its overall area is relatively small, resulting in relatively weak connection strength after electrical connection with the signal transmission wire 50. In this application, a folded portion 114 is also provided on the flexible conductor 10. This folded portion 114 extends to the outside of the other side of the flexible conductor and is positioned opposite the signal output electrical connection portion 113, causing the flexible conductor 10 to be formed into an approximately T-shaped or Y-shaped form. During product manufacturing, the folded portion 114 is folded towards the back of the flexible conductor 10 and extends to the signal output electrical connection portion 113, and is fixed by the flexible reinforcement 30 and the flexible binding member 40 to enhance the structural strength of the signal output electrical connection portion 113 and further strengthen the connection strength between the signal transmission electrical connection portion 113 and the signal transmission wire 50.
[0053] In this embodiment, the flexible reinforcement 30 is provided with a first winding portion 33, which is used to wind and fix the folded portion 114 and the signal output electrical connection portion 113 to fix the signal transmission wire 50 to the signal output electrical connection portion 113.
[0054] In some embodiments, the flexible binding member 40 is provided with a second winding portion 41, which is used to wind around the first winding portion 33, thereby further improving the connection strength between the signal transmission wire 50 and the signal transmission electrical connection portion 113.
[0055] Of course, in other embodiments, the first winding portion 33 may be provided only on the flexible reinforcing member 30, or the second winding portion 41 may be provided only on the flexible binding body 40. The specific choice can be made according to actual needs.
[0056] See Figure 1As shown, the flexible reinforcement 30 includes a flexible covering layer 34, which is a plate-like or sheet-like structure with a front and a back side. The front side of the flexible covering layer 34 has a first adhesion region 31 and a second adhesion region 32. A first winding portion 31 protrudes from the flexible covering layer 34. Both the emission exposure hole 311 and the receiving exposure hole 312 penetrate the first adhesion region 31. The front side of the flexible conductor 10 is adhered to at least a portion of the first adhesion region 31, and the back side of the flexible conductor 10 is adhered to at least a portion of the second adhesion region 32. In other words, the overall size of the flexible conductor 10 can be considered smaller than the first adhesion region 31 and the second adhesion region 32. After the front and back sides of the flexible conductor 10 are respectively adhered to the first adhesion region 31 and the second adhesion region 32, the first adhesion region 31 and the second adhesion region 32 are folded together and bonded to form a covering state for the flexible conductor 10.
[0057] See also Figure 1 As shown, the flexible binding member 40 has a fixing bonding area 42 and a binding bonding area 43. The second winding portion 41 protrudes from the flexible binding member 40. The fixing bonding area 42 is bonded to the side of the flexible reinforcing member 30 facing away from the back of the flexible conductor 10. The binding bonding area 43 is used to bond to the flexible reinforcing member 30 when the flexible reinforcing member 30 surrounds the part to be tested.
[0058] The flexible binding member 40 can be a strip of non-woven fabric. The fixing and bonding area 42 and the binding and bonding area 43 are adhesive layers disposed on the surface of the flexible binding member 40. The two areas are distinguished only by the different objects to be bonded. By bonding the fixing and bonding area 42 to the flexible reinforcing member 30, the flexible binding member 40 and the flexible reinforcing member 30 can be fixedly connected. When the flexible reinforcing member 30 is wrapped around the part to be tested, the binding and bonding area 43 can be bonded to the flexible reinforcing member 30 to cooperate with the flexible reinforcing member 30 for fixation.
[0059] Because the binding and bonding area 43 is provided with an adhesive layer, in order to ensure that the binding and bonding area 43 does not fail during the storage and transportation of the product, such as Figure 1 and Figure 2 As shown, the pulse oximeter probe 100 provided in this application also includes a release layer 60, wherein the release layer 60 can be a transparent plastic sheet. The release layer 60 is used to adhere to the flexible binding member 40. In a specific embodiment, it is at least adhered to the binding and bonding area 43 of the flexible binding member 40 and is peeled off before the flexible binding member 40 is fixed to the flexible reinforcement member 30.
[0060] See Figure 3As shown, the flexible conductor 10 includes a flexible insulating substrate 11 and a flexible conductive line 12. The flexible conductive line 12 is disposed on the front side of the flexible insulating substrate 11. The flexible conductor 10 can be a flexible circuit board, and the flexible insulating substrate 11 can be a flexible printed circuit board made of polyimide or polyester film, possessing the characteristics of being bendable, rollable, and foldable. The flexible conductive line 12 can be printed on the flexible insulating substrate 11 by screen printing. A transmitting electrical connection 111 and a receiving electrical connection 112 are respectively disposed at both ends of the flexible conductive line 12. A signal output electrical connection 113 and a folding part 114 are disposed opposite each other on the flexible insulating substrate 11.
[0061] In summary, the pulse oximeter probe provided by this utility model electrically connects the transmitting module and the receiving module to the transmitting electrical connection part and the receiving electrical connection part of the flexible conductor, respectively. This increases the contact area between the transmitting module and the receiving module and the flexible conductor. With this configuration, during the product manufacturing process and after the flexible reinforcement is wrapped around the detected area and fixed with the flexible binding member, the transmitting module and the receiving module are less likely to shift due to pulling on the flexible conductor. Furthermore, the connection parts between the transmitting module, the receiving module, and the flexible conductor are less likely to break, thus improving the accuracy of the detection results.
[0062] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
