Description

[0001] This application claims the priority of the prior application with the application number: 202420564979.4 and the application date: March 21, 2024. Technical Field

[0002] This application relates to the technical field of blood oxygen saturation detection devices, and particularly relates to an integrally formed probe clamping structure and a blood oxygen saturation probe. Background Art

[0003] A blood oxygen saturation probe (hereinafter referred to as a blood oxygen probe) is a sensor used to detect blood oxygen saturation. In some existing blood oxygen probes, it mainly includes a clamping structure and a detection unit; the clamping structure usually includes a housing and a clamping part. The clamping part is U-shaped, and an accommodation space matching the shape of a finger is formed inside it. The housing is arranged on the outer side of the clamping part away from the accommodation space; the housing is usually made of a hard material, such as plastic, and the clamping part is usually made of a flexible material, such as silica gel or rubber; the detection unit includes a light-emitting element (LED) and a photosensitive element (Photodiode, PD), which are respectively arranged on opposite sides inside the accommodation space. The light-emitting element and the photosensitive element are electrically connected to an external blood oxygen monitoring device through wires. A wire channel is provided between the housing and the clamping part, and the wires connecting the light-emitting element and the photosensitive element pass through the wire channel between the housing and the clamping part. During blood oxygen monitoring, the clamping part of the blood oxygen probe is clamped on the finger of the person to be measured, so that the finger of the person to be measured is located inside the accommodation space. The blood oxygen monitoring device controls the light-emitting element to emit red light and infrared light of a specific wavelength. The light emitted by the light-emitting element passes through the finger of the user and reaches the photosensitive element; when the blood oxygen saturation of the arterial blood flowing through the finger is different, the absorption rate of the light emitted by the light-emitting element by the arterial blood is also different, resulting in different light intensities passing through the finger. Therefore, the blood oxygen monitoring device can detect the light intensity passing through the finger through the photosensitive element, and thus calculate the blood oxygen saturation of the user.

[0004] For the existing Philips blood oxygen probe M1131, its clamping structure includes a housing made of a hard material and a clamping part made of a flexible material. During the assembly process, it is necessary to bond the hard material housing and the flexible material clamping part together, which has the disadvantage of inconvenient assembly. Moreover, the bonding between two materials with different properties is prone to the problem of being not firm. The quality of the bonding affects the quality of the blood oxygen probe. If the bonding is poor, it is easy to cause cracking and falling off, resulting in the problem of poor durability of the blood oxygen probe.

[0005] In addition, the patent with the publication number CN201333039Y and the patent name of a soft finger sleeve and a soft finger sleeve blood oxygen sensor composed thereof discloses a soft finger sleeve body, which is an integrally formed two-layer structure. The left and right sides of the soft finger sleeve body are connected, forming a front opening and a rear opening at the front and rear ends. When in use, after the finger of the person to be measured extends into from the rear opening, the upper layer and the lower layer of the soft finger sleeve body generate resilience through the connected parts on the left and right sides, so that the upper layer and the lower layer clamp the finger of the person to be measured. However, since this finger sleeve provides the clamping force through the structures on both sides, the structures on the left and right sides are relatively wide, and the two sides of the accommodating space for accommodating the finger cannot fit with the finger to be measured, which will form an obstacle to the adjacent finger. For example, when worn on the index finger, it will affect the movement of the middle finger, resulting in inconvenience during the detection process. Moreover, this finger sleeve will generate a relatively large pressure on thick fingers, affecting the use effect.

[0006] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0046] Beneficial effects: In a probe clamping structure and a blood oxygen saturation probe integrally formed in this application, by integrally forming the first clamping portion, the second clamping portion and the connecting portion, without the structure of a hard shell, the clamping structure of the blood oxygen probe does not require bonding, reducing the assembly process. And for the integrally formed probe clamping structure, its overall structure is stable, with strong durability, not prone to breakage or detachment, thus avoiding the problems of cracking and detachment easily caused by poor bonding. By opening the first wire channel to facilitate internal wiring, and opening an opening groove on the outer wall of the connecting portion, during the integral forming process, core pulling can be performed from the side where the opening groove is located to form a channel, so that the first wire channel communicates with the first accommodating cavity and the second accommodating cavity, thus making it more convenient to form the first wire channel in the integrally formed probe clamping structure, improving the durability of this probe clamping structure, and the opened opening groove is convenient for core pulling during the forming process, facilitating injection molding production. When the integrally formed probe clamping structure in this application is in use, the elastic force between the first clamping portion and the second clamping portion connected by the connecting portion is small, and it is difficult to stably fix the probe clamping structure on the finger by relying on its own elastic force. Therefore, after the part to be measured is inserted into the accommodating space, the first clamping portion and the second clamping portion are respectively fixed on both sides of the finger through the fixing member, so that the first clamping portion and the second clamping portion are closely attached to the part to be measured and are not prone to falling off, ensuring the detection stability and making the detection structure more accurate. Moreover, the accommodating space sleeves the part to be measured and does not form an obstacle to the human body part outside the part to be measured, making it more convenient to use during the detection process.

Detailed implementation manners

[0059] To make the objectives, technical solutions and advantages of the present application clearer and more definite, the following further describes the present application in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0060] The probe clamping structure in the prior art is formed by adhesively splicing a housing made of a hard material and a clamping part made of a flexible material. Not only is the assembly inconvenient, but also the problem of insecure adhesion easily occurs between the two materials with different properties, resulting in poor durability of the blood oxygen probe. Moreover, since the housing is made of a hard material, the bending of the finger is restricted, resulting in poor comfort during long-term use. In addition, hospitals need to frequently clean and disinfect the inner wall of the clamping structure after opening it. At this time, the housing made of a hard material will hinder the opening operation of the internal flexible material, making the cleaning and disinfection very inconvenient. Therefore, to solve the above problems, the following implementation manners are proposed in this improvement solution:

[0061] One implementation manner is as follows:

[0062] As Figure 1 、 Figure 4 shown, this embodiment proposes an integrally formed probe clamping structure 100 for installing a detection device 200. The detection device 200 includes a first detection element 210, a second detection element 220, and a connecting wire 230. For the convenience of structural description, in this embodiment, the detection of blood oxygen saturation of a finger is taken as an example for structural description. When the finger is inserted into the probe clamping structure 100, the front end of the finger is taken as the front, the direction where the back of the finger is located is taken as the upper, and the left and right directions of the finger are taken as the left and right directions for structural description. The structures of the components in this embodiment are described with the above directions as the reference directions.

[0063] As Figure 4 shown, the probe clamping structure 100 mainly includes: a first clamping portion 110, a second clamping portion 130, a connecting portion 150, and a fixing member 180. A first accommodation cavity 120 is formed in the first clamping portion 110, and the first accommodation cavity 120 is used for installing a first detection element 210. The second clamping portion 130 is disposed corresponding to the first clamping portion 110, and a second accommodation cavity 140 is formed in the second clamping portion 130; the second accommodation cavity 140 is used for installing a second detection element 220. The second clamping portion 130 and the first clamping portion 110 enclose an accommodation space 105 for accommodating a part to be measured, and the connecting portion 150 is connected to the first clamping portion 110 and the second clamping portion 130 only on one side of the accommodation space 105; in a specific structure, the first clamping portion 110 is located above, the second clamping portion 130 is located below, and the upper and lower ends of the connecting portion 150 are respectively connected to the front sides of the first clamping portion 110 and the second clamping portion 130. When a finger is placed in the accommodation space 105, the first clamping portion 110 and the second clamping portion 130 respectively contact the opposite upper and lower sides (the back of the finger and the pulp of the finger) of the finger, and the connecting portion 150 can contact the end portion (the fingertip) of the finger.

[0064] In other embodiments, as Figure 11 shown in (a) below, the upper and lower ends of the connecting portion 150 can also be respectively connected to the left side of the first clamping portion 110 and the left side of the second clamping portion 130; as Figure 11 shown in (b) below, the right side thereof is an opening for flipping and opening. Or the upper and lower ends of the connecting portion 150 are respectively connected to the right side of the first clamping portion 110 and the right side of the second clamping portion 130, so that the left side is an opening for flipping and opening. It is easy to think that the first clamping portion 110 and the second clamping portion 130 can also be respectively located on the left and right sides of the finger, or other corresponding directions.

[0065] The first clamping part 110, the second clamping part 130 and the connecting part 150 are integrally formed. The probe clamping structure 100 further includes a first wire channel 160 passing through the connecting part 150. The first wire channel 160 communicates with the first accommodating cavity 120 and the second accommodating cavity 140 respectively. The first wire channel 160 serves as a threading channel for the connecting wire 230 to facilitate the routing of the connecting wire 230. The first wire channel 160 includes an opening groove 161, and the opening groove 161 is provided on the outer side wall of the connecting part 150. In a specific structure, the area where the accommodating space 105 is located is the inner side of the probe clamping structure 100, and the side facing away from the accommodating space 105 is the outer side accordingly. The opening groove 161 is opened on the front outer side wall of the connecting part 150. One of the first detection element 210 and the second detection element 220 is a light-emitting element and the other is a light-sensitive element. The light-emitting element and the light-sensitive element are electrically connected to an external blood oxygen monitoring device through the connecting wire 230. During detection, the first detection element 210 and the second detection element 220 are respectively fixed at the corresponding two ends of the finger by the first clamping part 110 and the second clamping part 130. One emits a signal and the other receives a signal, and electrical signal transmission is performed with an external blood oxygen monitoring device through the connecting wire 230 to achieve blood oxygen saturation detection.

[0066] As Figures 1 - 3 shown, the fixing member 180 is arranged on the outer walls of the first clamping part 110 and the second clamping part 130. The fixing member 180 is used to fix the first clamping part 110 and the second clamping part 130 on the part to be measured, so that the part to be measured is fixed in the accommodating space 105. Since the integral molding uses a flexible material such as silica gel or rubber, and the elasticity of silica gel is small, only the connecting part 150 connects the first clamping part 110 and the second clamping part 130 on one side, resulting in a relatively small clamping force generated by the resilience of silica gel. It is difficult to stably fix the probe clamping structure 100 on the finger relying on the elasticity of silica gel itself. Therefore, after the finger to be measured is inserted into the accommodating space 105, the first clamping part 110 and the second clamping part 130 are respectively fixed on both sides of the finger by the fixing member 180, so that the first clamping part 110 and the second clamping part 130 are attached to the finger and are not easily detached, ensuring the detection stability. As Figure 3 、 Figure 6 shown, the fixing member 180 can be a winding belt, an adhesive tape or a C-shaped clip that is fixed on or separated from the probe clamping structure 100 and exists independently, or a magnetic attracting member, or a connecting belt with a magic tape fixed or separated on both the left and right sides of the first clamping part 110 and the second clamping part 130, etc.

[0067] In other alternative embodiments, as Figures 7 - 9 shown, the fixing member 180 can also be integrally formed with the first clamping part 110, the second clamping part 130 and the connecting part 150.

[0068] Specifically, the fixing member 180 includes a first binding band 181a. One end of the first binding band 181a is smoothly connected to the outer surface of the first clamping portion 110 and is integrally formed with the first clamping portion 110, the second clamping portion 130, and the connecting portion 150. The first binding band 181a is made of a flexible material such as silica gel or rubber, so the first binding band 181a can be bent and wound around the outer sides of the first clamping portion 110 and the second clamping portion 130. A first hook-and-loop fastener 182a is provided on the inner side of the first binding band 181a, and a second hook-and-loop fastener 182b is provided on the outer side of the first clamping portion 110 and / or the outer side of the first binding band 181a. One of the first hook-and-loop fastener 182a and the second hook-and-loop fastener 182b is a plush surface, and the other is a hook surface. When the first binding band 181a is wound around the outer sides of the first clamping portion 110 and the second clamping portion 130, the first hook-and-loop fastener 182a on the outer side of the first clamping portion 110 fits with the second hook-and-loop fastener 182b on the outer side of the first clamping portion 110 and / or the outer side of the first binding band 181a, so as to fix the first binding band 181a, enabling the blood oxygen probe to be fixed at the measured part. It can be understood that the side of the first binding band 181a smoothly connected to the first clamping portion 110 is its outer side, and the opposite side is its inner side. In other embodiments, the first binding band 181a may also be connected to the second clamping portion 130. Then, a first hook-and-loop fastener 182a is provided on the inner side of the first binding band 181a, and a second hook-and-loop fastener 182b is provided on the outer side of the second clamping portion 130 and / or the outer side of the binding band 181.

[0069] Such as Figure 10In another structure of the illustrated embodiment, the fixing member 180 may further include a second bundling band 181b. Both the first bundling band 181a and the second bundling band 181b are smoothly connected to the first clamping portion 110, and the connection positions are respectively located on opposite sides of the outer surface of the first clamping portion 110. The first clamping portion 110, the second clamping portion 130, the connecting portion 150, the first bundling band 181a, and the second bundling band 181b are integrally formed. The first bundling band 181a and the second bundling band 181b are made of flexible materials such as silica gel and rubber, so the first bundling band 181a and the second bundling band 181b can be bent. A first hook-and-loop fastener 182a is provided on the inner side of the first bundling band 181a, and a third hook-and-loop fastener 182c is provided on the outer side of the second bundling band 181b. One of the first hook-and-loop fastener 182a and the third hook-and-loop fastener 182c is a fuzzy surface, and the other is a hook surface. During use, the second bundling band 181b is bent so that its inner side abuts against the outer side of the second clamping portion 130, and the first bundling band 181a is bent so that the first hook-and-loop fastener 182a and the third hook-and-loop fastener 182c are mutually attached. Thus, the first bundling band 181a and the second bundling band 181b can fix the first clamping portion 110 and the second clamping portion 130 on the measured part, so that the blood oxygen probe can be fixed on the measured part.

[0070] In other embodiments, the first bundling band 181a and the second bundling band 181b may also be both connected to the second clamping portion 130, and the connection positions are respectively located on opposite sides of the outer surface of the second clamping portion 130. A first hook-and-loop fastener 182a is provided on the inner side of the first bundling band 181a, and a third hook-and-loop fastener 182c is provided on the outer side of the second bundling band 181b.

[0071] The integrally formed probe clamping structure 100 proposed in this embodiment, by integrally forming the first clamping portion 110, the second clamping portion 130 and the connecting portion 150, has no structure of a hard shell, so that the clamping structure of the blood oxygen probe does not require bonding of different materials, reducing the assembly process. And the integrally formed probe clamping structure 100 has a stable overall structure, strong durability, and is not prone to breakage or detachment, thus avoiding the problems of cracking and detachment that are easily caused by poor bonding. By opening the first wire channel 160 to facilitate internal wiring, and opening an opening groove 161 on the outer wall of the connecting portion 150, during the integrally formed production process, a channel can be formed through the core pulling of the mold from the side where the opening groove 161 is located, so that the first wire channel 160 communicates with the first accommodating cavity 120 and the second accommodating cavity 140, thus making it more convenient to form the first wire channel 160 in the integrally formed probe clamping structure 100 and improving the durability of the probe clamping structure 100. In addition, the connecting portion 150 connects the first clamping portion 110 and the second clamping portion 130 on one side to form an integral structure, and the first clamping portion 110 and the second clamping portion 130 can be turned over to clean and disinfect the inner wall. The turning process is easy, and the cleaning and disinfection are very convenient. When the elastic force between the first clamping portion 110 and the second clamping portion 130 connected by the connecting portion 150 is small, the first clamping portion 110 and the second clamping portion 130 are respectively fixed on both sides of the finger through the fixing member 180, so that the first clamping portion 110 and the second clamping portion 130 are attached to the part to be measured (such as a finger) and are not easily detached, ensuring the detection stability. When used for fingers of different thicknesses, the pressure on the finger comes from the force of tying by the fixing member 180 rather than the first clamping portion 110 and the second clamping portion 130 themselves. Therefore, the tying strength of the fixing member 180 can be adjusted to easily adapt to fingers of different thicknesses.

[0072] As Figure 1 、 Figure 4 shown, further, the first clamping portion 110, the second clamping portion 130 and the connecting portion 150 in this embodiment are all made of silica gel material. The silica gel material is soft and has good biocompatibility. The probe clamping structure 100 made of silica gel material is used to improve the comfort of the finger, has good durability and is also convenient for cleaning and disinfection. It is easy to think that the material of the probe clamping structure 100 can also be rubber, plastic, etc.

[0073] For the convenience of structural description, in this embodiment, mainly taking the connecting portion 150 being located on the front side of the accommodating space 105 as an example for specific structural description, and the following structural descriptions are all based on this structure.

[0074] As Figure 2 、 Figure 3 、 Figure 4As shown, further, a first fixing groove 112 is provided on the outer side wall of the first clamping portion 110, and a second fixing groove 132 is provided on the outer side wall of the second clamping portion 130. In a specific structure, the first fixing groove 112 may be located on the outer side wall of the first clamping portion 110 at an end far from the connecting portion 150, and the second fixing groove 132 may be located on the outer side wall of the second clamping portion 130 at an end far from the connecting portion 150. The fixing member 180 includes a winding tape that exists separately from the probe clamping structure 100. The winding tape is used to wind around the first fixing groove 112 and the second fixing groove 132. The first fixing groove 112 and the second fixing groove 132 provide a winding position for the winding tape, so that the winding tape will not deviate during the winding and fixing process. After the probe clamping structure 100 is clamped on the finger, the winding tape can be wound around the first fixing groove 112 and the second fixing groove 132 to fix the probe clamping structure 100. The winding tape can be a medical tape or a magic tape, etc. The winding tape can also be fixed on the first fixing groove 112 and the second fixing groove 132 in advance for convenient use.

[0075] As Figure 1 shown, compared with the comparative document CN201333039Y, the present blood oxygen probe does not provide clamping force through the structures on both sides, but provides clamping force through the fixing member 180. Therefore, the structures on the left and right sides can be relatively narrow. In this way, the width of the first clamping portion 110 and the width of the second clamping portion 130 both match the width of a single part to be measured, for example, match the width of a single finger or toe. In a specific structure, taking the distance in the left-right direction as the width, the widths of the first clamping portion 110 and the second clamping portion 130 are close to the finger width, so that the accommodating space 105 can just accommodate a single finger to enter. Thus, when performing blood oxygen saturation detection, the obstruction to the adjacent finger is reduced, and the interference to the detection of the finger being measured during the movement of the adjacent finger during the detection process is reduced.

[0076] As Figure 4 shown, further, the first wire channel 160 further includes: a first channel 162 and a second channel 163. The first channel 162 is opened in the first clamping portion 110 and communicates with the opening groove 161 and the first accommodating cavity 120. The second channel 163 is opened in the second clamping portion 130 and communicates with the opening groove 161 and the second accommodating cavity 140. Both the first channel 162 and the second channel 163 are straight-through structures. Thus, during the process of integrally molding the probe clamping structure 100 in a mold, the first channel 162 and the second channel 163 can be formed by mold core pulling from the side where the opening groove 161 is located. Adopting a straight-through structure can reduce the core pulling resistance during the molding process and facilitate the demolding process of mold core pulling. Both the first channel 162 and the second channel 163 are cylindrical holes. Adopting cylindrical holes can greatly reduce the core pulling resistance during the molding process, thus ensuring smoother core pulling during the molding process.

[0077] like Figure 4 As shown, further, the first accommodating cavity 120 specifically includes a first mounting groove 121, a second wire channel 122 and a wire outlet 123 that are connected. When the connecting portion 150 is located at the front side of the accommodating space 105, the wire outlet 123 is arranged at an end of the first clamping portion 110 away from the connecting portion 150; the first channel 162 is connected to the first mounting groove 121, the second wire channel 122 or the wire outlet 123. In the specific structure, the wire outlet 123 is arranged at the rear end of the first clamping portion 110, and the front and rear ends of the second wire channel 122 are respectively connected to the wire outlet 123 and the first mounting groove 121, and the connecting wire 230 can pass through the second wire channel 122 and pass out from the wire outlet 123. The direction in which the connecting wire 230 passes out is opposite to the pointing direction of the finger and is located on the back of the finger, thereby reducing the influence of the connecting wire 230 on the user's hand movement.

[0078] like Figure 4 As shown, further, in order to reduce the length of the first channel 162, thereby reducing the distance of the core pulling so as to facilitate the integrated molding of the probe clamping structure 100 and also facilitate the assembly of the connecting wire 230, in this embodiment, the first channel 162 is connected to the first installation groove 121, and the first channel 162 is directly connected to the rear side of the first installation groove 121, so that the distance of the first channel 162 is as short as possible. It is easy to imagine that the first channel 162 can also be directly connected to the second wire channel 122 or the wire outlet 123, as long as it can provide a routing space for the connecting wire 230.

[0079] like Figure 4 As shown, further, the second accommodating cavity 140 specifically includes a second mounting groove 141, the second mounting groove 141 corresponds to the position of the first mounting groove 121, and the second mounting groove 141 is used to install the second detection element 220. Thus, the first detection element 210 and the second detection element 220 can be located on opposite sides of the finger to achieve blood oxygen saturation monitoring.

[0080] like Figure 5As shown, further, a first groove 111 is provided on one side of the first clamping portion 110 facing the accommodating space 105, and a second groove 131 is provided on one side of the second clamping portion 130 facing the accommodating space 105. The user's part to be measured is accommodated through the first groove 111 and the second groove 131, so as to match the contour of the user's part to be measured. When performing blood oxygen saturation monitoring, the first groove 111 is brought into contact with the back of the finger, and the second groove 131 is brought into contact with the front of the finger, so as to reduce the pressure of the first clamping portion 110 and the second clamping portion 130 on the finger, thereby making the finger more comfortable. In addition, due to the provision of the first groove 111 and the second groove 131, the two side edges of the first groove 111 and the second groove 131 form a protrusion structure, and this protrusion structure can also play a role in blocking ambient light, blocking the light entering the accommodating space 105 from the left and right sides, especially preventing light from entering the detection device 200 in the first accommodating cavity 120 and the second accommodating cavity 140, so as to reduce the influence of ambient light on blood oxygen detection and improve the accuracy of blood oxygen detection.

[0081] As Figure 1 , Figure 4 shown, further, when the connecting portion 150 is located on the front side of the accommodating space 105, the included angle between the first clamping portion 110 and the connecting portion 150 is less than 90°, and the included angle between the second clamping portion 130 and the connecting portion 150 is greater than 90°. Thereby, the accommodating space 105 inside the connecting portion 150 forms an inclined surface that fits better with the finger end, increasing the contact area with the finger end, so as to reduce the pressure and reduce the sense of compression on the finger end, thereby improving the comfort of the finger end.

[0082] As Figure 4 shown, further, when the connecting portion 150 is located on the front side of the accommodating space 105, a nail accommodating groove 106 is provided on one side of the connecting portion 150 facing the accommodating space 105 and at a position close to the first clamping portion 110. In a specific structure, the nail accommodating groove 106 is located at the upper part of the front end of the accommodating space 105. When a user with long nails performs blood oxygen measurement, the user's nails are inserted into the nail accommodating groove 106, thereby facilitating blood oxygen measurement and improving practicability.

[0083] As another implementation manner:

[0084] As Figures 1 - 3As shown in the figure, this embodiment also provides a blood oxygen saturation probe, including: the integrally formed probe clamping structure 100 and the detection device 200 as described above. The detection device 200 is disposed in the first accommodation cavity 120 and the second accommodation cavity 140 of the probe clamping structure 100. The first accommodation cavity 120 and the second accommodation cavity 140 are both provided with light-transmitting windows 190 facing the accommodation space 105. The detection device 200 is used to detect the blood oxygen saturation of the user's part to be measured in the accommodation space 105 through the light-transmitting windows 190.

[0085] By using the integrally formed probe clamping structure 100 described above, the detection device 200 can be stably installed to achieve stable detection of blood oxygen saturation.

[0086] As Figure 2 shown in the figure, further, the detection device 200 specifically includes a first detection element 210, a second detection element 220, and a connecting wire 230. The first detection element 210 and the second detection element 220 are corresponding and are respectively disposed in the first accommodation cavity 120 and the second accommodation cavity 140. One of the first detection element 210 and the second detection element 220 is a light-emitting element, and the other is a light-sensitive element. The connecting wire 230 passes through the first wire channel 160 and is used to electrically connect the first detection element 210, the second detection element 220, and an external blood oxygen monitoring device. The first wire channel 160 not only enables the core pulling to proceed smoothly during the injection molding process by setting the opening groove 161, but also can provide a wiring path for the connecting wire 230, facilitating the circuit installation of the detection device 200.

[0087] Further, the connecting wire 230 can be provided with various structures. For example, the wires of the first detection element 210 and the wires of the second detection element 220 are separately arranged and are respectively led out through the wire outlet 123 to connect to an external blood oxygen monitoring device. It can also be that the wires of the second detection element 220 are extended to the first detection element 210, and then a wire is led out from the first detection element 210 to connect to an external blood oxygen monitoring device.

[0088] As Figure 2As shown in the figure, the connecting wire 230 in this embodiment specifically includes: a first wire 231 and a second wire 232. One end of the first wire 231 is electrically connected to the second detection element 220 in the second installation groove 141, and the other end passes through the first wire channel 160, the first installation groove 121, the second wire channel 122, and the wire outlet 123 in sequence and then extends out to be electrically connected to an external blood oxygen monitoring device; one end of the second wire 232 is electrically connected to the first detection element 210 in the first installation groove 121, and the other end passes through the second wire channel 122 and the wire outlet 123 and then extends out to be electrically connected to an external blood oxygen monitoring device. The first detection element 210 and the second detection element 220 are respectively electrically connected by the first wire 231 and the second wire 232, so that the wires can all be routed in the channels formed by core-pulling in the first clamping portion 110, the second clamping portion 130, and the connecting portion 150, optimizing the entire probe clamping structure 100 and making it more convenient to install the detection device 200.

[0089] In the specific structure, one of the first detection element 210 and the second detection element 220 is a light-emitting element, and the other is a light-sensitive element. For example, in this embodiment, the first detection element 210 is a light-emitting element, and the second detection element 220 is a light-sensitive element. One end of the first wire 231 is electrically connected to the second detection element 220, and the other end passes through the first wire channel 160 to enter the first accommodating cavity 120, and passes through the second wire channel 122 and then exits from the wire outlet 123 to be electrically connected to an external blood oxygen monitoring device, so that the blood oxygen monitoring device can control the second detection element 220 to monitor light information; the second wire 232 is electrically connected to the first detection element 210, and the other end is used to be electrically connected to the blood oxygen monitoring device, so that the blood oxygen monitoring device can control the light emission of the first detection element 210; the blood oxygen monitoring device can be an external vital sign monitoring instrument or a blood oxygen monitoring module provided on the blood oxygen probe. The wire segments of the first wire 231 and the second wire 232 in the second wire channel 122 and the wire outlet 123 can be two independent wires or combined into the same wire.

[0090] When assembling the first wire 231, one end of the first wire 231 can be first passed from the first accommodating cavity 120 through the first channel 162 to the opening groove 161, and then from the opening groove 161 through the second channel 163 to the second accommodating cavity 140, or the steps opposite to the above steps can be carried out; after the first wire 231 is assembled, glue is poured into the opening groove 161 to achieve fixation and sealing.

[0091] In the above-described embodiment, the blood oxygen detection of the finger of the subject is taken as an example for illustration. However, the application of the proposed solution is not limited to the detection of the finger of the subject. After adjusting the shape of the accommodating space, it can also be applied to the blood oxygen detection of other parts, such as toes, earlobes, etc.

[0092] In summary, the present application proposes an integrally formed probe clamping structure and a blood oxygen saturation probe. By providing an opening groove, the probe clamping structure is convenient for core pulling during the integrally forming process to form a first wire channel, enabling the first wire channel to communicate with the first accommodating cavity and the second accommodating cavity, thereby realizing the integrally forming process of the probe clamping structure and improving the durability of the probe clamping structure. The fixing member 180 can fit fingers of different thicknesses without exerting too much pressure on the fingers. Moreover, the integrally formed flexible probe clamping structure can be easily opened to clean and disinfect the inner wall.

[0093] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
