Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a probe structure for physical sign monitoring. Background Art

[0002] A probe for physical sign monitoring can monitor the oxygen concentration (i.e., blood oxygen saturation) in the blood of a person to be measured, or electrocardiogram, electroencephalogram signals, etc. For example, a blood oxygen probe can monitor by clamping the finger of the person to be measured. However, the fingers of the person to be measured have different thicknesses. In order to match different fingers, the blood oxygen probe may be displaced, resulting in the situation that the signal receiving position and the signal transmitting position on it are misaligned and fail, which will lead to the failure of the monitoring signal.

[0052] The present invention will be further described below with reference to the accompanying drawings.

[0053] Some existing probe structures for physical sign monitoring, such as blood oxygen probes, are set in the form of chucks. When in use, the two chucks are clamped on the finger of the person to be measured, and the chucks and the finger of the person to be measured are tied together as a whole so that the signal receiving position and the signal transmitting position thereon are in close contact with the skin of the finger for monitoring. However, no special connection and fixing structure is provided on the blood oxygen probe. Therefore, when tying, it cannot be ensured that the two probes are completely aligned, and there will be a situation where the signal receiving position and the signal transmitting position are misaligned with each other, resulting in monitoring failure. Some other existing blood oxygen probes are set in the form of finger rings, and the size of the finger ring is adjusted by an elastic band. However, when using this kind of blood oxygen probe, there is a problem that the skin of the finger fails to contact the specified position on the finger ring, so there will also be a situation of monitoring failure.

[0054] Based on the above technical problems, the present invention provides a probe structure for physical sign monitoring, including a first probe 1 and a second probe 2. Among them, the first probe 1 can be a blood oxygen probe, which is used to contact the finger of the person to be measured, so as to monitor the oxygen concentration (i.e., blood oxygen saturation) in the blood of the person to be measured. The second probe 2 can be an electrocardiogram probe, which is used to contact the body skin of the person to be measured to obtain an electrocardiogram signal; the second probe 2 can also be an electroencephalogram probe, which is used to contact the head of the person to be measured to obtain an electroencephalogram signal.

[0055] Example 1

[0056] As Figures 1 - 12 shown, the first probe 1 includes a first chuck 11 and a second chuck 12 for clamping the finger 3 of the person to be measured. The extending directions of the first chuck 11 and the second chuck 12 are both the same as the extending direction of the finger 3 of the person to be measured (such as Figure 1 shown, the Y-axis direction).

[0057] As Figure 1 and Figure 2 shown, the first chuck 11 and the second chuck 12 are arranged oppositely and a cavity 18 capable of accommodating the finger of the person to be measured is formed therebetween. The cavity 18 extends along the extending direction of the first chuck 11 or the second chuck 12. The first chuck 11 and the second chuck 12 can move relative to each other in the direction where they are arranged oppositely (i.e., the Z-axis direction) to change the size of the cavity 18. By adjusting the size of the cavity 18, for example, by changing the size of the cavity 18 in the Z-axis direction, the cavity 18 can be adapted to fingers of different thicknesses, so that the first probe 1 can measure the fingers 3 of the person to be measured with different thicknesses.

[0058] Furthermore, the first chuck 11 and the second chuck 12 are connected by a fixing unit 13, and the fixing unit 13 is used to align the first chuck 11 and the second chuck 12 at a predetermined position and fix them. Among them, the predetermined position means that the signal receiving position (such as the position where the signal receiver is located) on the first chuck 11 is aligned with the signal transmitting position (such as the position where the signal transmitter is located) on the second chuck 12; or the signal transmitting position (such as the position where the signal transmitter is located) on the first chuck 11 is aligned with the signal receiving position (such as the position where the signal receiver is located) on the second chuck 12, so as to improve the accuracy of wearing the first probe 1 and reduce the risk of monitoring failure.

[0059] In the present Embodiment 1, the fixing unit 13 is configured as a fixing belt, which is a strip-shaped structure with a certain hardness and deformability, such as an elastic belt, etc. It has a certain elasticity and can generate a certain elastic deformation during fixing. Alternatively, the fixing belt can also be a binding belt, which can be an elastic belt or a non-elastic belt. The fixing belt can be wound around the first chuck 11 and the second chuck 12 to fix the two. Therefore, the fixing belt can be a strip-shaped structure with or without elasticity.

[0060] Specifically, as Figure 4 shown, a first guiding groove 111 extending in a direction perpendicular to its extending direction (such as the X-axis direction shown in Figure 1 the figure) is provided on the outer side of the first chuck 11. Two opposite first protruding portions 113 are provided on the outer surface of the first chuck 11. The first protruding portions 113 extend from one side portion of the first chuck 11 to the other side portion of the first chuck 11 along the width direction of the first chuck 11. Therefore, it can be understood that the first guiding groove 111 is defined by the two first protruding portions 113 and the outer surface of the first chuck 11. Therefore, the distance between the two first protruding portions 113 is the width of the first guiding groove 111.

[0061] Similarly, a second guiding groove 121 extending in a direction perpendicular to its extending direction (such as the X-axis direction shown in Figure 1 the figure) is provided on the outer side of the second chuck 12. Two opposite second protruding portions 123 are provided on the outer surface of the second chuck 12. The second protruding portions 123 extend from one side portion of the second chuck 12 to the other side portion of the second chuck 12 along the width direction of the second chuck 12. Therefore, it can be understood that the second guiding groove 121 is defined by the two second protruding portions 123 and the outer surface of the second chuck 12. Therefore, the distance between the two second protruding portions 123 is the width of the second guiding groove 121. Preferably, the width of the first guiding groove 111 is the same as the width of the second guiding groove 121.

[0062] When the fixing belt is an elastic strip-shaped structure, since it can undergo elastic deformation, the width of the strip-shaped structure after deformation can be less than or equal to the width of the first guiding groove 111 (or the second guiding groove 121) so as to smoothly enter the first guiding groove 111 and the second guiding groove 121.

[0063] When the fixing belt is a non-elastic strip-shaped structure, since it cannot undergo elastic deformation, the width of the strip-shaped structure can be less than or equal to the width of the first guiding groove 111 (or the second guiding groove 121) so as to smoothly enter the first guiding groove 111 and the second guiding groove 121.

[0064] When the fixing band is respectively connected to the first guiding groove 111 and the second guiding groove 121 to fix the first chuck 11 and the second chuck 12, the two side walls 112 of the first guiding groove 111 (i.e., the sides opposite to the first protruding part 113) and the two side walls 122 of the second guiding groove 121 (i.e., the sides opposite to the second protruding part 123) can guide the fixing band, so that when the fixing band connects the first chuck 11 and the second chuck 12, the first guiding groove 111 and the second guiding groove 121 can be aligned in the Z direction (because if the first guiding groove 111 and the second guiding groove 121 are not aligned, the fixing band cannot enter the second guiding groove 121 from the first guiding groove 111 or enter the first guiding groove 111 from the second guiding groove 121), thereby fixing the first chuck 11 and the second chuck 12.

[0065] A connecting structure is provided on the fixing unit 13. After passing through the first guiding groove 111 and the second guiding groove 121 and winding around once, the fixing unit 13 can be fixed through the connecting structure 15. Among them, the connecting structure 15 is connected to one or more of a part of the fixing unit 13, the first guiding groove 111, and the second guiding groove 121.

[0066] As Figure 5 shown, the connecting structure 15 includes a magic tape 151 (or a magic hook). Correspondingly, a paste layer (fluffy layer) that cooperates with the magic tape 151 can be provided on one or more of a part of the fixing unit 13, the first guiding groove 111, and the second guiding groove 121. For example, a paste layer is provided on the first guiding groove 111 (or the second guiding groove 121). The connecting structure 15 is located at the end of the fixing unit 13. Therefore, after the fixing unit 13 passes through the first guiding groove 111 and the second guiding groove 121 and winds around once, the magic tape 151 thereon can be fixedly connected to the paste layer on the first guiding groove 111 (or the second guiding groove 121) to fix the first chuck 11 and the second chuck 12.

[0067] Alternatively, optionally, the magic tape 151 can also be provided on the front side of the fixing unit 13, and the paste layer can be provided on the back side, and vice versa. Then, after the fixing unit 13 passes through the first guiding groove 111 and the second guiding groove 121 and winds around once, the magic tape 151 thereon can be fixed to its own paste layer, so that the tightness of the binding can be adjusted to adapt to the test subjects with different finger thicknesses.

[0068] Conceivably, adhesive layers can also be provided on the front side of the fixing unit 13 and on the first guiding groove 111 (for example, on both sides of the first guiding groove 111 in the X direction), and magic tapes 151 can be provided on the back sides at both ends of the fixing unit 13. When fixing, the magic tape 151 on the back side of one end of the fixing unit 13 is first fixed to the connecting layer on the first guiding groove 111, so as to facilitate dragging the other end of the fixing unit 13 for winding. After it winds around the first guiding groove 111 and the second guiding groove 121 for one circle, the magic tape 151 on the back side of the other end of the fixing unit 13 can be pasted to the adhesive layer on its own front side, so that the fixing unit 13 can be more stably connected to the first guiding groove 111 and the second guiding groove 121.

[0069] As Figure 6 shown, the connecting structure 15 includes a magnetic attraction structure 152. The magnetic attraction structure 152 can be, for example, a magnetic buckle, and a plurality of them can be provided. The plurality of magnetic attraction structures 152 can be arranged at intervals along the extending direction of the fixing unit 13. Magnets can be correspondingly provided on the first guiding groove 111 and / or the second guiding groove 121. After the fixing unit 13 winds around the first guiding groove 111 and the second guiding groove 121 for one circle, the magnetic attraction structure 152 thereon can be attracted to the magnets on the first guiding groove 111 and / or the second guiding groove 121 for fixing. By fixing the different magnetic attraction structures 152 on the fixing unit 13 to the magnets on the first guiding groove 111 and / or the second guiding groove 121, the tightening degree of the binding of the fixing unit 13 can be adjusted to adapt to the test subjects with different finger thicknesses.

[0070] As Figure 7 shown, the connecting structure 15 includes an adhesive layer 153. The adhesive layer 153 can be fixedly or replaceably provided on the fixing unit 13. The adhesive layer 153 can be pasted repeatedly. When its pasting performance deteriorates, it can be peeled off from the fixing unit 13 and a new adhesive layer 153 can be replaced or a new adhesive layer 153 can be directly covered thereon. The adhesive layer 153 can be, for example, a silica gel adhesive layer, which is in the form of a double-sided tape.

[0071] Correspondingly, a part of the fixing unit 13, one or more of the first guiding groove 111 and the second guiding groove 121 have smooth surfaces that cooperate with the adhesive layer. After the fixing unit 13 passes through the first guiding groove 111 and the second guiding groove 121 and winds around for one circle, that is, the adhesive layer 153 thereon can be pasted and fixed to the smooth surface of a part of the fixing unit 13, one or more of the first guiding groove 111 and the second guiding groove 121.

[0072] As Figure 3 and Figure 4As shown, the inner side of the first chuck 11 (i.e., the side close to the second chuck 12) is configured as a first arcuate inner wall 114 that curves away from the second chuck 12, and the inner side of the second chuck 12 (i.e., the side close to the first chuck 11) is configured as a second arcuate inner wall 124 that curves away from the first chuck 11. The first arcuate inner wall 114 and the second arcuate inner wall 124 are respectively used to contact the outer and inner sides of the finger 3 of the person to be measured. By providing the first arcuate inner wall 114 and the second arcuate inner wall 124, they can better fit the finger 3 of the person to be measured, so that the first chuck 11 and the second chuck 12 can be aligned as much as possible in the X direction. In addition, this arcuate concave structure of the first arcuate inner wall 114 and the second arcuate inner wall 124 can ensure that the finger can only be in the most concave position of the first arcuate inner wall 114 and the second arcuate inner wall 124, and the finger is wrapped as a whole, thus avoiding the situation where the finger is placed in an undesired position and cannot contact the signal receiving position or the signal transmitting position.

[0073] As Figure 2 and Figure 4 shown, one of the first arcuate inner wall 114 and the second arcuate inner wall 124 is provided with a signal receiver, and the other is provided with a signal transmitter. The signal receiver can be a signal receiving sensor, and the signal transmitter can be a signal transmitting sensor. The signal transmitter projects energy into the blood vessels and capillaries in the finger 3 of the person to be measured, and then the signal receiver receives and monitors the attenuated energy. The energy emitted by the signal transmitter can be light or other forms of energy, and the signal receiver transmits the signal indicating the monitored attenuated energy to a signal processing device such as a blood oxygen meter. The blood oxygen meter can calculate one or more physiological parameters of the finger 3 of the person to be measured. Therefore, it is usually desirable to position the signal transmitter opposite to the signal receiver, such as above and below the finger 3 of the person to be measured. Therefore, the first guide groove 111 and the second guide groove 121 are connected by a fixing band to ensure that the first chuck 11 and the second chuck 12 are aligned in the Z direction, and the first arcuate inner wall 114 and the second arcuate inner wall 124 are in contact with the outer and inner sides of the finger 3 of the person to be measured, so that the first chuck 11 and the second chuck 12 are aligned in the X direction, that is, the first chuck 11 and the second chuck 12 are aligned according to the predetermined position, whereby the signal transmitter and the signal receiver can be in the desired position.

[0074] It should be noted that the connection method and the signal interaction method between the first probe 1 and a signal processing device such as a blood oxygen meter can adopt various methods in the prior art, and the present invention will not elaborate on this.

[0075] Furthermore, as Figure 2 、 9 and Figure 10As shown, the first chuck 11 and the second chuck 12 are of a split structure, and the end of the first chuck 11 and the end of the second chuck 12 are connected by a telescopic connector 14. As Figure 2 shown, the telescopic connector 14 can be a wavy structure, as Figure 9 shown, the telescopic connector 14 can be a V-shaped structure or a U-shaped structure, as Figure 10 shown, the telescopic connector 14 can also be a square structure. Therefore, the shape of the telescopic connector 14 can be diverse, and its purpose is that when the first chuck 11 and the second chuck 12 move relative to each other, they deform, so that when the first chuck 11 and the second chuck 12 move away from each other, they are respectively abutted against the outer side and the inner side of the finger 3 of the person to be measured under the action of the elastic force of the telescopic connector 14, so that the signal transmitters and signal receivers on the first chuck 11 and the second chuck 12 can be in close contact with the skin of the finger 3 of the person to be measured, so as to improve the accuracy of monitoring.

[0076] Alternatively, conceivably, the first chuck 11 and the second chuck 12 can also be of an integral structure, and the two form a whole.

[0077] Optionally, both the first arc-shaped inner wall 114 and the second arc-shaped inner wall 124 are elastic walls, and when the elastic walls contact the skin of the patient, they can slightly undergo elastic deformation, so as to be better adapted to the finger of the patient to improve comfort and monitoring accuracy.

[0078] Optionally, as Figure 4 and Figure 8 shown, a breathable structure layer 125 is provided on the first arc-shaped inner wall 114 and / or the second arc-shaped inner wall 124. The breathable structure layer 125 is a woven material layer or a sponge structure. More specifically, the breathable structure layer 125 can be made of cloth, for example. One of the purposes of providing the breathable structure layer 125 is to ensure the breathability of the part in contact with the skin of the patient during use, so as to improve the comfort of use; the second purpose is that the breathable structure layer 125 can ensure a certain air flow rate in the cavity 18, so as to improve the accuracy of monitoring.

[0079] Optionally, the breathable structure layer 125 can also be an elastic layer. Similarly, when the elastic layer contacts the skin of the patient, it can slightly undergo elastic deformation, so as to be better adapted to the finger of the patient to improve comfort and monitoring accuracy.

[0080] The third purpose of providing the breathable structure layer 125 is that the breathable structure layer 125 is detachably connected to the first arcuate inner wall 114 and / or the second arcuate inner wall 124. Therefore, the breathable structure layer 125 can be replaced. When it needs to be cleaned after a long period of use or is used by multiple patients, the breathable structure layer 125 can be removed from the first arcuate inner wall 114 and / or the second arcuate inner wall 124 for replacement, thereby increasing the service life of the first probe 1, enabling the first probe 1 to be utilized for a long time, and reducing the waste of medical resources.

[0081] The connection manner between the breathable structure layer 125 and the first arcuate inner wall 114 and / or the second arcuate inner wall 124 can be similar to the connection structure 15. For example, the breathable structure layer 125 can be connected to the first arcuate inner wall 114 and / or the second arcuate inner wall 124 through one or more of Velcro, magnetic attraction structures, and adhesive layers.

[0082] As Figure 8 shown, a first connection layer 126 is provided on the back side of the breathable structure layer 125, and a second connection layer 127 is provided on the surface of the first arcuate inner wall 114 and / or the second arcuate inner wall 124. The first connection layer 126 and the second connection layer 127 are adhesively bonded to each other, so that the breathable structure layer 125 is fixed on the surface of the first arcuate inner wall 114 and / or the second arcuate inner wall 124. The first connection layer 126 and the second connection layer 127 can be adhesively bonded or connected through, for example, Velcro, magnetic attraction structures, or adhesive layers.

[0083] The first arcuate inner wall 114 and the second arcuate inner wall 124 have arcuate surfaces. Therefore, the breathable structure layer 125, the first connection layer 126, and the second connection layer 127 can correspondingly have arcuate structures to facilitate closer fitting of the first arcuate inner wall 114 and the second arcuate inner wall 124.

[0084] Example 2

[0085] As Figure 11 and Figure 12 shown, the difference between the second embodiment 2 and the above-mentioned first embodiment 1 is that the fixing unit 13 is configured as a guiding structure. As Figure 11 shown, the guiding structure includes guiding columns 132 respectively connected to the first chuck 11 and the second chuck 12. The guiding columns 132 are connected to the first chuck 11 and the second chuck 12 through elastic members 131. The first chuck 11 and / or the second chuck 12 can move along the guiding columns 132 to approach or move away from each other.

[0086] Specifically, as Figure 12As shown, at least two first protrusions are provided on the side of the first chuck 11, and each first protrusion protrudes outward in a direction perpendicular to the side of the first chuck 11, and a first guiding hole 118 is provided in each first protrusion. Correspondingly, at least two second protrusions are also provided on the side of the second chuck 12, and each second protrusion protrudes outward in a direction perpendicular to the side of the second chuck 12, and a second guiding hole 128 is provided in each second protrusion.

[0087] The first guiding hole 118 is aligned with the corresponding second guiding hole 128, and both ends of the guiding column 132 are respectively connected to the first guiding hole 118 and the second guiding hole 128. The elastic member 131 is respectively arranged in the first guiding hole 118 and the second guiding hole 128 and is connected to the guiding column 132. Therefore, the first chuck 11 and / or the second chuck 12 can be pulled to increase the distance between them, that is, to change the size of the cavity 18 in the Z-axis direction, so that fingers of different thicknesses can be inserted into the cavity 18. After the finger 3 of the person to be measured is inserted into the cavity 18, under the action of the elastic member 131, the first chuck 11 and the second chuck 12 are pulled to closely fit against the outer and inner sides of the finger 3 of the person to be measured.

[0088] As Figure 12 shown, in order to ensure that the movement trajectories of the first chuck 11 and / or the second chuck 12 are along the Z-axis direction, four guiding columns 132 can be provided, which are respectively located around the first chuck 11 (the second chuck 12). Thus, when clamping the finger 3 of the person to be measured, the first chuck 11 and / or the second chuck 12 can move strictly along the extension direction of the guiding column 132, avoiding the situation where the first chuck 11 and the second chuck 12 are misaligned during the movement, resulting in the signal receiver and the signal transmitter not being aligned.

[0089] As Figure 12 shown, the first guiding hole 118 can be set as a blind hole, and the second guiding hole 128 can be set as a through hole. Or the first guiding hole 118 can be set as a through hole, and the second guiding hole 128 can be set as a blind hole. The guiding column 132 can penetrate the first guiding hole 118 or the second guiding hole 128. Therefore, when it is necessary to change the size of the cavity 18, the size of the cavity 18 can be changed by only moving the first chuck 11 or only moving the second chuck 12. This method can ensure that the signal receiver and the signal transmitter are always aligned, avoiding the misalignment risk when moving the first chuck 11 and the second chuck 12 simultaneously.

[0090] The same parts of this Embodiment 2 and the above Embodiment 1 will not be elaborated again.

[0091] Example 3

[0092] As Figure 13 and Figure 14As shown, the second probe 2 is an electrocardiogram probe, which is used to contact the body skin of the person to be measured to obtain an electrocardiogram signal. The electrocardiogram probe includes a patch structure 21 for contacting the body (trunk part) of the person to be measured and a signal collection device 22 detachably connected to the patch structure 21. The signal collection device 22 is connected to an electrocardiogram processing terminal (electrocardiograph) through a cable 23.

[0093] Similar to the connection structure 15 of the above-mentioned Embodiment 1, the patch structure 21 and the signal collection device 22 can also be connected by Velcro, a magnetic attraction structure or an adhesive layer. As Figure 14 shown, a first adhesive layer 211 is provided on one side of the patch structure 21 close to the signal collection device 22, and a second adhesive layer 221 is provided on one side of the signal collection device 22 close to the patch structure 21. The first adhesive layer 211 and the second adhesive layer 221 can be the hook and fluff layers of Velcro, or can be magnetic buttons and magnets, or can be an adhesive layer and a smooth surface, etc.

[0094] Therefore, when it is necessary to remove the second probe 2, the patch structure 21 can be separated from the signal collection device 22, and the signal collection device 22 can be repeatedly connected without removing the patch structure 21, so it is more convenient to use.

[0095] Furthermore, in order to improve comfort, a breathable structure layer 125 can be provided on the side of the patch structure 21 away from the signal collection device 22, which can adopt various forms described in the above-mentioned Embodiment 1 to improve breathability when contacting the skin.

[0096] In addition, compared with the existing electrocardiogram receiving device, the thickness of the patch structure 21 of the present invention is smaller. Therefore, even when the patch structure 21 is attached to the body of the person to be measured, it will not cause too much discomfort to the person, so it is more comfortable to wear and use.

[0097] Example 4

[0098] As Figure 15 and Figure 16 shown, the second probe 2 is an electroencephalogram probe, which is used to contact the body (head) of the person to be measured to obtain an electroencephalogram signal. Similarly, the electroencephalogram probe includes a patch structure 21 for contacting the head of the person to be measured and a signal collection device 22 detachably connected to the patch structure 21. The signal collection device 22 is connected to an electroencephalogram processing terminal (electroencephalograph) through a cable 23.

[0099] Similar to the connection structure 15 of the above-mentioned Embodiment 1, the patch structure 21 and the signal collection device 22 can also be connected by Velcro, a magnetic attraction structure or an adhesive layer. As Figure 16As shown, a first adhesive layer 211 is provided on one side of the patch structure 21 close to the signal collection device 22, and a second adhesive layer 221 is provided on one side of the signal collection device 22 close to the patch structure 21. The first adhesive layer 211 and the second adhesive layer 221 can be the hook and fluff layers of Velcro, or can be magnetic buttons and magnets, or can be an adhesive layer and a smooth surface, etc.

[0100] Therefore, when it is necessary to remove the second probe 2, the patch structure 21 can be separated from the signal collection device 22, and the signal collection device 22 can be repeatedly connected without removing the patch structure 21, so it is more convenient to use.

[0101] Furthermore, in order to improve comfort, a breathable structure layer 125 can be provided on the side of the patch structure 21 away from the signal collection device 22, and it can adopt various forms described in the above-mentioned Embodiment 1 to improve the breathability when contacting the skin.

[0102] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
