Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a finger cot device for obtaining the blood oxygen saturation of a target object. Background Technology

[0002] Blood oxygen saturation is an important clinical parameter for the human body. As a medical device for monitoring blood oxygen, a pulse oximeter sensor works by emitting red and infrared light. This light passes through the bloodstream, and the different absorption characteristics of hemoglobin and oxyhemoglobin in the blood result in varying light intensities received by the sensor. The received information is then transmitted via cable to a monitoring device, which uses algorithms to calculate the blood oxygen saturation level, enabling real-time monitoring.

[0003] In related technologies, finger-type pulse oximeters include a soft finger sleeve body and a pulse oximetry detection component disposed within the soft finger sleeve body. During use, the inner wall of the finger sleeve fits snugly against the finger joint; however, the finger sleeve can easily detach from the finger when the patient moves the joint, causing measurement interruption. Utility Model Content

[0004] The main purpose of this invention is to provide a finger sleeve device for obtaining the blood oxygen saturation of a target object, aiming to prevent the measurement from being interrupted due to the finger sleeve device falling off the finger during the measurement process.

[0005] To achieve the above objectives, this utility model proposes a finger sleeve device for obtaining the blood oxygen saturation of a target detection object, comprising a finger sleeve body and a detection component;

[0006] The finger sleeve body is provided with a receiving cavity, which is used to accommodate the finger of the target detection object;

The second segment includes endpoint P2, peak S21, trough V21, peak S22, trough V22, peak S23, and endpoint P3 in sequence.

[0017] In some embodiments, when the finger of the target object is inserted into the receiving cavity for measurement, all or part of the first sidewall corresponding to the curve segment between the peak S11 and the peak S12 covers the inner side of the finger, and all or part of the second sidewall corresponding to the line segment between the trough V21 and the trough V22 covers the outer side of the finger, wherein the outer side of the finger is the side where the fingernail is located.

[0018] In some embodiments, the distance between the trough V21 and the crest S11 is less than the distance between the crest S22 and the trough V12, and the distance between the trough V22 and the crest S12 is less than the distance between the crest S22 and the trough V12; the line segment between the endpoint P1 and the crest S11 is an arc segment, the line segment between the endpoint P2 and the trough V21 is an arc segment, the line segment between the trough V22 and the endpoint P3 is an arc segment, and the line segment between the crest S12 and the endpoint P4 is an arc segment; and the distance between the crest S21 and the trough V11 is greater than the distance between the endpoints P1 and P2, and the distance between the crest S23 and the trough V13 is greater than the distance between the endpoints P3 and P4.

[0019] In some embodiments, the inner sidewall of the finger sleeve device is made of an elastic material, the rib is disposed on the first sidewall, the outer contour of the rib protrudes from the first sidewall, and the projection of the outer contour on the plane in the finger insertion direction is a curved segment.

[0020] In some embodiments, two ribs are sequentially provided in the depth direction of the finger sleeve body. One of the ribs can fill all or part of the recessed area on the inside of the finger corresponding to the knuckle near the transmitter or the receiver. The other rib can fill all or part of the recessed area on the inside of the finger corresponding to the knuckle near the opening of the finger sleeve device. The inside of the finger is the side facing away from the fingernail.

[0021] In some embodiments, the first sidewall is provided with a first mounting groove for mounting the transmitter, the transmitter being disposed in the first mounting groove via a first mounting base, the third sidewall is provided with a second mounting groove for mounting the receiver, the receiver being disposed in the second mounting groove via a second mounting base, both the first mounting groove and the second mounting groove are filled with resin filler for sealing, and both the openings of the first mounting groove and the second mounting groove are covered with transparent caps.

[0022] In some embodiments, the finger sleeve device further includes a cable, one end of which extends into the finger sleeve body and is electrically connected to the detection component, and the other end of which is adapted to be electrically connected to a monitoring device.

[0023] In the technical solution of this utility model, the finger sleeve device includes a finger sleeve body and a detection component; the finger sleeve body has a receiving cavity for accommodating the finger of the target detection object; the detection component is disposed inside the finger sleeve body and is used to measure the blood oxygen saturation of the target detection object; the receiving cavity has ribs protruding from the inner sidewall of the receiving cavity; the detection component includes a transmitter and a receiver, one of which is disposed on the upper side of the inner sidewall of the receiving cavity, and the other is disposed on the lower side of the inner sidewall of the receiving cavity; when the finger of the target detection object is inserted into the receiving cavity for measurement... During measurement, in the direction of finger insertion, the transmitter and receiver are located between the free end of the finger and the rib. When the finger of the target object is inserted into the receiving cavity for measurement, the inner wall of the receiving cavity can deform, and all or part of the rib can fill the recessed area of ​​the finger to restrict the movement of the finger in the direction of leaving the receiving cavity. The rib also prevents external light from interfering with the detection components. The recessed area is the recessed area on the inner side of the finger corresponding to the finger joint, and the inner side of the finger is the side facing away from the fingernail. When the finger is removed from the finger sleeve body, the inner wall of the receiving cavity can return to its original shape. It can be understood that this invention, by providing ribs protruding from the inner wall of the receiving cavity of the finger sleeve body, allows the ribs to fill all or part of the recessed area of ​​the finger when the finger of the target object is inserted into the receiving cavity for measurement, thus restricting the movement of the finger in the direction of leaving the receiving cavity, thereby improving the anti-drop effect of the finger sleeve device and avoiding measurement interruption. Furthermore, because the inner wall of the receiving cavity of the finger sleeve body can deform and has self-recovery capability, the wearing comfort of the finger sleeve device is effectively guaranteed.

[0041] This utility model proposes a finger sleeve device for obtaining the blood oxygen saturation of a target object. It can be applied to medical instruments such as monitors. The target object can be a patient or a person undergoing physical examination, or it can be an animal with fingers. It is not limited here.

[0042] Reference Figures 1 to 7In one embodiment of this utility model, the finger sleeve device 100 includes a finger sleeve body 10 and a detection component 20; the finger sleeve body 10 is provided with a receiving cavity 10a for receiving the finger 200 of the target detection object; the detection component 20 is disposed inside the finger sleeve body 10 and is used to measure the blood oxygen saturation of the target detection object; the receiving cavity 10a is provided with a rib 11 protruding from the inner sidewall of the receiving cavity 10a; the detection component 20 includes a transmitter 21 and a receiver 22, one of which is disposed on the upper side of the inner sidewall of the receiving cavity 10a, and the other is disposed on the lower side of the inner sidewall of the receiving cavity 10a; when the finger 200 of the target detection object is inserted into the receiving cavity 10a for measurement, the insertion of the finger 200... In terms of orientation, the transmitter 21 and receiver 22 are located on the finger sleeve body 10 in the area between the free end of the finger 200 and the rib 11. When the finger 200 of the target object is inserted into the receiving cavity 10a for measurement, the inner wall of the receiving cavity 10a can deform and all or part of the rib 11 can fill the recessed area 201 of the finger 200 of the target object to restrict the finger 200 from moving in the direction of leaving the receiving cavity 10a, and the rib 11 can prevent external light from interfering with the detection component 20. The recessed area 201 of the finger 200 is the recessed area 201 on the inner side of the finger 200 corresponding to the knuckle of the finger 200, and the inner side of the finger 200 is the side facing away from the fingernail of the finger 200. When the finger 200 is removed from the finger sleeve body 10, the inner wall of the receiving cavity 10a can return to its original state.

[0043] It should be noted that, for reference Figures 1 to 7 The free end of finger 200 refers to the end of finger 200 that contacts or is opposite to the bottom wall 115 of the receiving cavity 10a in the direction of finger insertion. During measurement, after finger 200 is inserted into the target detection position of receiving cavity 10a, the free end of finger 200 contacts or is at a certain distance from the bottom wall 115 of receiving cavity 10a. The transmitter 21 and receiver 22 are located in the corresponding area of ​​the finger sleeve body 10 between the free end of finger 200 and the rib 11, roughly at the fingertip and nail position of the target detection object finger 200, respectively located on the side closer to the fingertip and the side closer to the nail.

[0044] To ensure the comfort of the target subject during blood oxygen saturation testing and to accommodate different individuals and finger sizes 200, thereby expanding the applicability of the finger sleeve device 100, the finger sleeve body 10 or the inner wall of the receiving cavity 10a of this invention can deform under the pressure of the finger 200. After the finger 200 is inserted into the target testing position, the ribs 11 on the inner wall of the receiving cavity 10a at least partially fill the recessed area 201 of the finger 200, effectively securing fingers 200 of different sizes. After the test is completed, the finger 200 is completely withdrawn from the receiving cavity 10a, and the finger sleeve body 10 automatically returns to its natural state. That is, the finger sleeve body 10, either as a whole or partially, has a certain self-recovery capability, can change shape under external force, and returns to its original state after the external force is removed.

[0045] In this embodiment, the number of ribs 11 can be one, two or more, and the specific shape is not limited. Any structure that can restrict the movement of the finger 200 in the direction of detachment from the receiving cavity 10a is acceptable.

[0046] It is understood that by providing ribs 11 protruding from the inner wall of the receiving cavity 10a of the finger sleeve body 10, when the finger 200 of the target object is inserted into the receiving cavity 10a for measurement, the ribs 11 can completely or partially fill the recessed area 201 of the finger 200, thereby restricting the movement of the finger 200 in the direction of detachment from the receiving cavity 10a, thus improving the anti-dislodgement effect of the finger sleeve device 100 and avoiding measurement interruption. In addition, since the inner wall of the receiving cavity 10a of the finger sleeve body 10 can deform and has good self-recovery ability, the wearing comfort of the finger sleeve device 100 is effectively guaranteed.

[0047] Furthermore, in some applications, the reinforcing bar 11 can also be designed to indicate whether the finger 200 of the target object is inserted correctly. During insertion, when the reinforcing bar 11 falls precisely into the joint recess of the finger 200, the finger 200 is exactly in the target detection position, which greatly improves the ease of use of the finger sleeve device 100 and ensures the accuracy of the detection results.

[0048] In one embodiment, primarily referring to Figure 1 , Figure 2 , Figures 6 to 8The finger sleeve device 100 has a front and a back, and is provided with a direction indicator pattern Di to indicate that the front side is the correct side and should face upwards during use. The length direction of the rib 11 is defined as the X-axis direction, the depth direction of the finger sleeve body 10 is defined as the Y-axis direction, and the height direction of the rib 11 is defined as the Z-axis direction. The projection of the outer contour of the rib 11 onto a plane perpendicular to the insertion direction of the finger 200 (along the plane formed by the X-axis and Z-axis) is a curve segment. The curve segment may include a first curve segment 101, a second curve segment 102, and a third curve segment 103. The second curve segment 102 has two... The ends are respectively connected to the first curve segment 101 and the third curve segment 103. When all or part of the rib 11 can fill the recessed area 201 of the finger 200 of the target object, the contour of the rib 11 corresponding to the second curve segment 102 can fill all or part of the recessed area 201 of the finger 200 of the target object. The curve segment is roughly wavy. The connection point between the first curve segment 101 and the second curve segment 102 is the first peak, the connection point between the second curve segment 102 and the third curve segment 103 is the second peak, and the trough is located on the second curve segment 102.

[0049] By adopting the aforementioned rib 11 structure, the limiting function of the rib 11 can be achieved while using less material and without excessively increasing the wall thickness of the finger sleeve body 10 at this location. This minimizes the impact on the self-recovery performance of the finger sleeve body 10, further enhancing the comfort of using the finger sleeve device 100. Furthermore, during use, the pressure at the contact point between the finger sleeve device 100 and the human finger 200 is relatively low, hardly affecting the weak perfusion parameters, resulting in higher measurement accuracy and better comfort.

[0050] In one embodiment, primarily referring to Figure 1 , Figure 6 and Figure 9 The projection of the outer contour of the rib 11 onto a plane perpendicular to the insertion direction of the finger 200 is a curved segment, roughly in the shape of a "U". When the finger 200 of the target object is inserted into the receiving cavity 10a for measurement, the contour of the rib 11 corresponding to the "U" shape can fill all or part of the recessed area 201 of the finger 200. This design can more stably restrict the movement of the finger 200 in the direction of detachment from the receiving cavity 10a, effectively ensuring the anti-slip effect of the finger sleeve device 100. This rib 11 structure is also easier to process and manufacture.

[0051] In existing technologies, the inner wall of the finger sleeve has narrow grooves, making cleaning and disinfection difficult.

[0052] In this regard, the present invention has also made relevant improvements:

[0053] In one embodiment, reference is made to Figures 1 to 7The inner wall of the receiving cavity 10a includes a first sidewall 111, a third sidewall 113, a second sidewall 112, and a fourth sidewall 114 connected in sequence. The first sidewall 111 faces the second sidewall 112, and the third sidewall 113 faces the fourth sidewall 114. A plane perpendicular to the insertion direction of the finger 200 is used as a reference plane. The insertion direction of the finger 200 is defined as the length direction of the finger sleeve device 100. In the length direction, the insertion port of the finger sleeve device 100 is taken as the starting point, and the side of the transmitter 21 or receiver 22 closest to the insertion port is taken as the ending point. The main reference plane is... Figure 3 and Figure 4 The inner wall shape is designed as follows: at any point within the distance from the starting point to the end point, the inner wall contour of the cut surface of the finger sleeve device 100 is a closed curve with one end closed. The curve may include a first segment, a third segment, a second segment, and a fourth segment connected in sequence. The third and fourth segments are roughly straight segments. The first and third segments are connected by endpoint P1. The third and second segments are connected by endpoint P2. The second and fourth segments are connected by endpoint P3. The fourth segment and the first segment are connected by endpoint P4. The first segment is a wavy line segment. The first segment includes endpoint P1, trough V11, peak S11, trough V12, peak S12, trough V13, and endpoint P4 in sequence. The second segment includes endpoint P2, peak S21, trough V21, peak S22, trough V22, peak S23, and endpoint P3 in sequence.

[0054] It is understood that by adopting the above-mentioned inner wall structure of the receiving cavity 10a, this utility model not only enables the finger sleeve body 10 to have good self-recovery ability and adapt to fingers 200 of different thicknesses, but also effectively solves the technical problem of the existing finger sleeve cavity being difficult to clean and disinfect because the inner wall of the receiving cavity 10a does not have narrow grooves (for example, the curve segment with P1 as the starting point and V21 as the ending point does not form a narrow area and there are no dead corners that are difficult to clean).

[0055] In this embodiment, when the finger 200 of the target object is inserted into the receiving cavity 10a for measurement, all or part of the first sidewall 111 corresponding to the curve segment between peak S11 and peak S12 covers the inner side of the finger 200, and all or part of the second sidewall 112 corresponding to the line segment between trough V21 and trough V22 covers the outer side of the finger 200, the outer side of the finger 200 being the side where the fingernail is located. This allows the receiving cavity 10a to better fit the shape of the finger 200, the finger 200 to be better enveloped by the finger sleeve body 10, and prevents light from passing through the side of the finger 200, thus improving the accuracy of the measurement results.

[0056] In some embodiments, the main reference is Figure 3 and Figure 4The distance between trough V21 and crest S11 is less than the distance between crest S22 and trough V12, and the distance between trough V22 and crest S12 is less than the distance between crest S22 and trough V12. The line segment between endpoint P1 and crest S11 is an arc segment, the line segment between endpoint P2 and trough V21 is an arc segment, the line segment between trough V22 and endpoint P3 is an arc segment, and the line segment between crest S12 and endpoint P4 is an arc segment. Furthermore, the distance between crest S21 and trough V11 is greater than the distance between endpoint P1 and endpoint P2, and the distance between crest S23 and trough V13 is greater than the distance between endpoint P3 and endpoint P4. This design ensures that the connections between the sidewalls of the receiving cavity 10a have smooth, rounded corners, further preventing dead zones during cleaning and disinfection.

[0057] To ensure the finger sleeve device 100 has sufficient elasticity to accommodate fingers 200 of varying thicknesses, guaranteeing comfortable wear and preventing slippage, thereby reducing the likelihood of measurement interruptions, in one embodiment, reference is made to... Figures 1 to 7 The inner wall of the finger sleeve device 100 can be made of elastic material. Ribs 11 are provided on the first side wall 111. The outer contour of the ribs 11 protrudes from the first side wall 111. The projection of the outer contour on the plane in the finger insertion direction (i.e., the Y-axis direction shown in the figure) is a curved segment.

[0058] In some embodiments, two ribs 11 may be sequentially provided in the depth direction of the finger sleeve body 10. One rib 11 may fill, in whole or in part, the recessed area 201 on the inner side of the finger 200 corresponding to the knuckle near the transmitter 21 or receiver 22. The other rib 11 may fill, in whole or in part, the recessed area 201 on the inner side of the finger 200 corresponding to the knuckle near the opening of the finger sleeve device 100. The inner side of the finger 200 is the side facing away from the fingernail. In other words, in some cases, to ensure the stability of the finger sleeve device 100, the two ribs 11 respectively fill the recessed areas 201 of the two knuckles. This can greatly enhance the anti-slip effect of the finger sleeve device 100 and significantly reduce the probability of measurement interruption.

[0059] To facilitate the installation of the detection component 20 and minimize the product size while maintaining the self-recovery capability of the receiving cavity 10a of the finger sleeve body 10, in one embodiment, the following is mainly referred to Figure 6The first sidewall 111 is provided with a first mounting groove 111a for mounting the transmitter 21. The transmitter 21 is mounted in the first mounting groove 111a via a first mounting base 23. The third sidewall 113 is provided with a second mounting groove 113a for mounting the receiver 22. The receiver 22 is mounted in the second mounting groove 113a via a second mounting base 24. Both the first mounting groove 111a and the second mounting groove 113a are filled with resin filler 25 for sealing. The openings of the first mounting groove 111a and the second mounting groove 113a are covered with transparent covers.

[0060] Furthermore, to achieve electrical signal transmission and monitor the pulse oxygen saturation of the target object, in one embodiment, the following is mainly referred to Figure 1 and Figure 6 The finger sleeve device 100 may also include a cable 30, one end of which extends into the finger sleeve body 10 and is electrically connected to the detection component 20, and the other end of which is adapted to be electrically connected to the monitoring device.

[0061] In this embodiment, the finger sleeve device 100 further includes a transparent window 26 made of silicone material, so that the detection light emitted by the transmitter 21 of the detection component 20 can be emitted to the finger 200 and received by the receiver 22. The transmitter 21 can be a light-emitting diode, and the receiver 22 can be a photodiode; neither is limited here.

[0062] When assembling the transmitter 21, firstly, a portion of the cores of the multi-core cable 30 is soldered to the light-emitting diode (LED). Then, the first mounting base 23 is inserted into the first mounting groove 111a, and resin filler 25 is poured in to seal and protect the photodiode. Finally, it is assembled with the silicone transparent window 26.
