Description

Technical Field

[0001] The invention relates to the technical field related to blood oximeters, and in particular to an adjustable finger-clip type pulse blood oximeter. Background Art

[0002] A pulse oximeter is a device that detects blood oxygen saturation, where blood oxygen saturation represents the change in oxygen content in the blood. It is generally believed that the normal value of blood oxygen saturation should not be lower than 94%. Any value below 94% is considered to be insufficient oxygen supply. Taking a portable finger-clip pulse oximeter as an example, some finger-clip pulse oximeters have a built-in reset spring clip to provide a rotational clamping force, and the upper and lower shells are used to rotate and clamp the finger to be tested around a rotatable axis.

[0003] However, the above-mentioned traditional finger-clip pulse oximeter has a narrow contact area with the finger to be measured due to the oblique clamp opening of the clamp measurement method, and the finger-clip pulse oximeter is prone to fall off.

[0004] In order to solve the above problems, a Chinese patent with publication number CN221411208U discloses a finger-clip pulse oximeter, including a bottom shell, a top shell is arranged on the top of the bottom shell, and adhesive plates are fixedly arranged on the outer sides of the left and right ends of the bottom shell and the left and right ends of the top shell, a strip is fixedly arranged on the outer side of the adhesive plate, a flexible finger belt is fixedly arranged at one end of the strip, a silicone pad is fixedly arranged on the inner wall of the flexible finger belt, a cylinder shell is fixedly arranged on the outer sides of the left and right ends of the bottom shell and the left and right ends of the top shell, a spring damper is fixedly arranged between the inner wall of the top end and the inner wall of the bottom end of the cylinder shell, a pressing sheet is fixedly arranged on the top end of the bottom shell and the bottom end of the top shell, and a guide rod is fixedly arranged on the bottom end of the pressing sheet located at the top, and a flexible pressing clamp and an anti-falling structure of the finger-clip pulse oximeter are formed by the bottom shell, the top shell, the adhesive plate, the strip, the flexible finger belt, the silicone pad, the cylinder shell, the spring damper, the pressing sheet and the guide rod.

[0005] However, the above scheme still has some defects in actual use, such as: when separating the lower clamp (bottom shell) and the upper clamp (top shell), both hands are required to pull the lower clamp and the upper clamp respectively to pull them apart, which is not suitable for one-handed operation; in addition, when the finger-clip pulse oximeter is in use, the two sides of the lower clamp and the upper clamp are not closed, and the external light shines into the inside of the finger-clip pulse oximeter along the side, which will affect the normal use of the finger-clip pulse oximeter. Summary of the invention

[0006] In order to solve the defects in the prior art, the present invention provides an adjustable finger-clip pulse oximeter.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0017] As a preferred technical solution of the present invention, the driving unit includes a rotating disk rotatably arranged inside the outer cylinder, the rotating disk is provided with two groups of rotating grooves symmetrically arranged with an axis center, and the upper moving part and the lower moving part are respectively fixed with sliding columns at positions corresponding to the rotating grooves.

[0018] As a preferred technical solution of the present invention, a through hole is provided at the center of the rotating disk, and at least one set of limiting grooves is provided at a position of the rotating disk corresponding to the outer side of the through hole;

[0019] The control unit comprises:

[0023] As a preferred technical solution of the present invention, a support plate is fixedly provided on the outer cylinder near the pressing handle.

[0024] As a preferred technical solution of the present invention, a sliding groove is provided at one end of the fixing portion close to the upper clamping plate and the lower clamping plate, and sliding blocks are fixedly provided at positions of the upper clamping plate and the lower clamping plate corresponding to the sliding groove.

[0025] As a preferred technical solution of the present invention, the upper clamping plate includes an upper plate body and upper bosses arranged at both ends of the upper plate body, and an upper clamping groove is formed between the two upper bosses;

[0026] The lower clamping plate comprises a lower plate body and lower bosses arranged at both ends of the lower plate body, a lower clamping groove is formed between the two lower bosses, and the upper clamping groove and the lower clamping groove form a clamping area.

[0027] As a preferred technical solution of the present invention, a shading mechanism is provided between the lower plate body and the upper plate body, and the shading mechanism comprises:

[0032] The beneficial effects of the present invention are:

[0033] 1. In the present invention, an upper moving part and a lower moving part are provided to cooperate with a driving mechanism. By applying pressure to the control unit, the driving unit can be driven to work and then the upper moving part and the upper clamping plate can be controlled to move upward along the vertical groove, and the lower moving part and the lower clamping plate can be controlled to move downward along the vertical groove, that is, the upper clamping plate and the lower clamping plate are controlled to separate from each other. After the user puts the finger into the clamping area, the finger can be clamped between the upper clamping plate and the lower clamping plate by stopping applying pressure to the control unit, eliminating the traditional clamping method for clamping the finger. This arrangement improves the clamping effect of the oximeter on the finger and avoids the situation where the finger-clip pulse oximeter falls off.

[0035] 3. In the present invention, a shading mechanism is provided. When a finger is placed inside the clamping area, the upper splint and the lower splint will move away from each other. At the same time, the upper splint will drive the shading cloth to move, thereby shielding the two sides of the lower splint and the upper splint. This arrangement can avoid the influence of external light on the blood oxygen meter, ensuring that the blood oxygen meter can be used normally in an environment with strong light.

DETAILED DESCRIPTION

[0048] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0049] Embodiment 1

[0050] like Figure 1-Figure 5 As shown, an adjustable finger-clip pulse oximeter comprises an upper clamping plate 1, a lower clamping plate 2, a fixing part 3, an upper movable part 4, a lower movable part 5 and a driving mechanism 6, wherein the upper clamping plate 1 and the lower clamping plate 2 are arranged opposite to each other, and the upper clamping plate 1 and the lower clamping plate 2 are separated from or approached from each other in the vertical direction to form a clamping area; the fixing part 3 is provided with a vertical groove 31 in the vertical direction; the upper movable part 4 is slidably arranged in the interior of the vertical groove 31 and is fixedly connected to the upper clamping plate 1; the lower movable part 5 is slidably arranged in the interior of the vertical groove 31 and is fixedly connected to the lower clamping plate 2; the driving mechanism 6 comprises a driving unit 61 for driving the upper movable part 4 and the lower movable part 5 to move in the interior of the vertical groove 31, a control unit 62 for controlling the operation of the driving unit 61 and an elastic unit 63 for resetting the control unit 62;

[0051] By applying pressure to the control unit 62, the driving unit 61 can be driven to work, thereby controlling the upper moving part 4 and the upper clamping plate 1 to move upward along the vertical groove 31, and controlling the lower moving part 5 and the lower clamping plate 2 to move downward along the vertical groove 31;

[0052] After the application of pressure stops, driven by the elastic unit 63 , the upper moving part 4 and the upper clamping plate 1 will move downward, and the lower moving part 5 and the lower clamping plate 2 will move upward.

[0053] Among them, by setting the upper moving part 4 and the lower moving part 5 to cooperate with the driving mechanism 6, the driving unit 61 can be driven to work by applying pressure to the control unit 62, thereby controlling the upper moving part 4 and the upper clamping plate 1 to move upward along the vertical groove 31, and controlling the lower moving part 5 and the lower clamping plate 2 to move downward along the vertical groove 31, that is, controlling the upper clamping plate 1 and the lower clamping plate 2 to separate from each other. After the user puts the finger into the clamping area, the finger can be clamped between the upper clamping plate 1 and the lower clamping plate 2 by stopping applying pressure to the control unit 62, thereby eliminating the traditional clamping method for clamping the finger. This setting is more conducive to the clamping effect of the finger and avoids the situation where the finger-clip pulse oximeter falls off.

[0054] It should be noted that an LED light source is fixedly installed inside the upper splint 1, which usually contains two wavelengths of red light (660nm) and infrared light (940nm). A photodetector is fixedly installed inside the lower splint 2. When the device is clamped on the fingertips, the LED light source emits red light and infrared light. These light rays penetrate the skin and blood vessels. When the blood flows, oxygenated hemoglobin and deoxygenated hemoglobin will absorb these two lights in different proportions. After the light is partially absorbed by the blood vessels, it is received by the photodetector on the other side of the sensor. This process forms an optical signal. By analyzing the data received by the photodetector, the pulse oximeter can measure the changes in the pulse wave and the degree of light absorption. The oxygen saturation and pulse frequency of the blood will be displayed in real time on the display screen of the device, which enables users to quickly obtain their own health data.

[0055] Further, if Figure 4 As shown, the driving mechanism 6 also includes an outer cylinder 64 fixedly connected to the fixing part 3, and the outer cylinder 64 includes a first cavity 641 for placing the driving unit 61 and a second cavity 642 for placing the control unit 62, and the first cavity 641 and the second cavity 642 are separated by a partition 643.

[0056] Among them, the outer cylinder 64 is used to store the driving unit 61 and the control unit 62 on the one hand, and on the other hand, the outer cylinder 64 is mainly used to be fixedly connected with the fixed part 3, so as to provide good support for the fixed part 3, thereby ensuring that the upper moving part 4 and the lower moving part 5 can move stably on the fixed part 3.

[0057] Further, if Figure 5-Figure 6As shown, the driving unit 61 includes a rotating disk 611 rotatably arranged inside the outer cylinder 64. Furthermore, the rotating disk 611 is rotatably connected to the partition 643. Two groups of rotating grooves 6111 symmetrically arranged with an axis center are opened on the rotating disk 611. The upper moving part 4 and the lower moving part 5 are respectively fixed with sliding columns 612 at positions corresponding to the rotating grooves 6111.

[0058] When the rotating disk 611 rotates on the partition plate 643 , driven by the sliding column 612 , the upper moving part 4 and the lower moving part 5 will move away from or toward each other, thereby driving the upper clamping plate 1 and the lower clamping plate 2 to move away from or toward each other.

[0059] Further, if Figure 6-Figure 7 As shown, a through hole 6112 is provided at the center of the rotating disk 611, and at least one set of limiting grooves 6113 is provided at a position of the rotating disk 611 corresponding to the outer side of the through hole 6112;

[0060] The control unit 62 includes a telescopic rod 621, a guide portion 622, a connecting rod 623 and a pressing handle 624. The telescopic rod 621 is connected to the fixing portion 3 through an elastic unit 63 and the telescopic rod 621 is slidably arranged inside the through hole 6112; the guiding portion 622 is spirally arranged on the outside of the telescopic rod 621 and matches with the limiting groove 6113; one end of the connecting rod 623 is fixedly connected to the telescopic rod 621, and the other end extends out of the outer cylinder 64 and is fixedly connected to the pressing handle 624;

[0061] A support plate 644 is fixedly disposed on the outer cylinder 64 at a position close to the pressing handle 624 .

[0062] The driving mechanism 6 includes an outer cylinder 64, a pressing handle 624 and a support plate 644. When in use, the outer cylinder 64 is clamped by the index finger and the middle finger, and the index finger and the middle finger are pressed against the support plate 644. The thumb is then used to push the pressing handle 624 to realize the operation of the present invention, thereby realizing the separation of the upper splint 1 and the lower splint 2 by one hand, which is more convenient for use.

[0063] When the product is in the initial position, the end faces of the upper splint 1 and the lower splint 2 are fitted together. When it needs to be used, the pressing handle 624 is pushed to drive the telescopic rod 621 to move inside the through hole 6112 through the connecting rod 623 and squeeze the elastic unit 63. The guide portion 622 set on the outside of the telescopic rod 621 will cooperate with the limiting groove 6113 to drive the rotating disk 611 to rotate, and finally drive the upper splint 1 to separate from the lower splint 2. When the thumb is released and no longer applies pressure to the pressing handle 624, the elastic unit 63 is reset to drive the telescopic rod 621 to move in the opposite direction and drive the rotating disk 611 to rotate in the opposite direction, and finally drive the upper splint 1 and the lower splint 2 to get closer again.

[0064] It should be noted that the number of the guide parts 622 and the limiting grooves 6113 is the same and both are arranged in two groups. When the telescopic rod 621 slides inside the through hole 6112, the arrangement of the two groups of guide parts 622 can stably drive the rotating disk 611 to rotate.

[0065] Further, if Figure 5 As shown, a sliding groove 32 is formed at one end of the fixing portion 3 close to the upper clamping plate 1 and the lower clamping plate 2 , and sliding blocks 7 are fixedly provided at positions of the upper clamping plate 1 and the lower clamping plate 2 corresponding to the sliding groove 32 .

[0066] During the movement of the upper and lower clamping plates 1 and 2, by setting the slider 7 to slide inside the sliding groove 32, the sliding stability of the upper and lower clamping plates 1 and 2 can be further improved to ensure that the upper and lower clamping plates 1 and 2 will not deflect relative to the fixing part 3.

[0067] Embodiment 2

[0068] The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0069] Further, if Figure 8 As shown, the upper clamping plate 1 includes an upper plate body 11 and upper bosses 12 arranged at both ends of the upper plate body 11, and an upper clamping groove is formed between the two upper bosses 12;

[0070] The lower clamping plate 2 includes a lower plate body 21 and lower bosses 22 arranged at both ends of the lower plate body 21 , a lower clamping groove is formed between the two lower bosses 22 , and the upper clamping groove and the lower clamping groove form a clamping area.

[0071] Further, if Figure 8-Figure 9As shown, a shading mechanism 8 is arranged between the lower plate body 21 and the upper plate body 11, and the shading mechanism 8 includes a coil spring unit 81, a fixing rod 82 and a shading cloth 83. The coil spring unit 81 is arranged inside the lower plate body 21 and is arranged at a position corresponding to the lower boss 22, and at least one group of the coil spring units 81 is arranged at the lower end of the lower boss 22; the fixing rod 82 is fixedly arranged at the lower end of the upper boss 12; one end of the shading cloth 83 is fixedly connected to the fixing rod 82, and the other end is fixedly connected to the end of the coil spring unit 81.

[0072] Among them, by setting the shading mechanism 8, when the finger is placed inside the clamping area, the upper clamping plate 1 and the lower clamping plate 2 will move away from each other. At the same time, the fixing rod 82 in the upper clamping plate 1 and the coil spring unit 81 in the lower clamping plate 2 cooperate with each other to drive the shading cloth 83 to unfold, and block the two sides of the lower clamping plate 2 and the upper clamping plate 1. This setting can avoid the influence of external light on the blood oxygen meter, ensuring that the blood oxygen meter can be used normally in an environment with strong light;

[0073] When the upper clamping plate 1 and the lower clamping plate 2 approach each other again, the coil spring unit 81 will drive the shade cloth 83 to contract, so as to ensure that the shade cloth 83 will not be stacked between the lower clamping plate 2 and the upper clamping plate 1 .

[0074] It should be noted that the lower boss 22 is provided with a receiving groove 221 at a position corresponding to the shading cloth 83, and the shading cloth 83 can pass through the receiving groove 221 and be connected to the fixing rod 82;

[0075] Preferably, two groups of coil spring units 81 are provided in the lower boss 22 on each side.

[0076] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
