Description

Technical Field

[0001] This utility model relates to the field of wearable medical device technology, and in particular to an adjustable blood oxygen clip finger sleeve that prevents slippage. Background Technology

[0002] Currently, finger clip pulse oximeters use non-invasive infrared technology to measure blood oxygen saturation in fingers, toes, ears, etc., and express the test results in digital form, usually as a percentage. The typical blood oxygen saturation of a healthy human body is 90% to 100%, but it can be as low as 60%.

[0003] Some existing finger clip pulse oximeters typically have a default clamping force set to a moderate range. However, this setting cannot well accommodate users with fingers of varying sizes. Furthermore, if the clamping force is too strong or too weak for the user, it will reduce the accuracy of the measurement and affect the comfort of wearing it. To address these issues, an adjustable pulse oximeter clip finger sleeve that prevents slippage is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable pulse oximeter clip finger sleeve that prevents slippage, aiming to improve the problem that the clamping force of the existing finger clip pulse oximeter cannot be adjusted.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable pulse oximeter finger clip that prevents slippage, comprising a lower housing and a detector, a central shaft rotatably connected to the top center of the lower housing, an upper housing rotatably connected to the outside of the central shaft, an airbag fixedly connected to the front side of the lower housing, a connecting tube fixedly connected to the inside of the lower housing, a balloon fixedly connected to the rear side of the lower housing, a one-way valve provided at the rear end of the balloon, a spring plate fixedly connected to the inside of the balloon, and an adjustment component for deflating the airbag at the top of the balloon;

[0006] As a further description of the above technical solution:

[0007] The adjustment assembly includes an hourglass tube, the outside of which is fixedly connected to the middle of the top of the balloon, and the inside of which is movably connected to a piston.

[0008] As a further description of the above technical solution:

[0009] The lower housing is rotatably connected to the top center of the upper housing, and the detector is located in the middle of the upper housing.

[0010] As a further description of the above technical solution:

[0011] A torsion spring is sleeved on the outside of the central shaft. The top end of the torsion spring engages with the top end of the upper housing, and the bottom end of the torsion spring engages with the top end of the lower housing.

[0012] As a further description of the above technical solution:

[0013] The top end of the connecting tube is fixedly connected to the bottom end of the airbag cushion, and the end of the connecting tube away from the airbag cushion is fixedly connected to the rear end of the balloon.

[0014] As a further description of the above technical solution:

[0015] A first ring is fixedly connected to the front side of the upper housing, and a second ring is fixedly connected to the outer rear side of the upper housing. Velcro straps are provided on the outside of the first ring and the second ring.

[0016] As a further description of the above technical solution:

[0017] The Velcro strap is fitted over the outside of the lower housing, and a connecting wire is provided at the end of the upper housing away from the central axis.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by pressing the operating balloon, external air is drawn in through a one-way valve and flows into the interior, thereby inflating the connecting wire. This allows the balloon to compress and wrap around the user's fingers, adapting to different finger sizes for measurement and preventing the finger clip from loosening, thus increasing the accuracy of the measurement data;

[0020] 2. In this invention, after clamping the user's finger, the Velcro strap is pulled through the surrounding holes to overlap its surface. At this time, the hook and loop sides of the Velcro strap adhere to each other, thereby achieving a circumferential fixation of the finger clip, further increasing the finger clip's firmness and effectively preventing it from falling off.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 3 This utility model provides an embodiment of an adjustable pulse oximeter finger clip that prevents slippage, comprising a lower housing 1 and a detector 5. A support block for supporting the rotation of a central shaft 2 is provided in the middle of the lower housing 1. The central shaft 2 is rotatably connected to the top center of the lower housing 1. The central shaft 2 provides a shaft for mounting a torsion spring 4, and at the same time ensures that the upper housing 1 and the lower housing 3 can rotate flexibly under the action of the torsion spring 4.

[0030] The upper housing 3 is rotatably connected to the outside of the central shaft 2. The middle part of the lower housing 1 is rotatably connected to the top center of the upper housing 3. The upper housing 3 is rotatably connected to the lower housing 1 through the central shaft 2. Its material is the same as that of the lower housing 1, and it also has the excellent properties of medical-grade plastic. The detector 5 is located in the middle of the upper housing 3. The detector 5 integrates a precision photoelectric detection element and a complex circuit system, which can accurately detect important physiological parameters such as blood oxygen saturation and pulse rate of the human finger.

[0031] A torsion spring 4 is sleeved on the outside of the central shaft 2. The top end of the torsion spring 4 engages with the top end of the upper housing 3, and the bottom end of the torsion spring 4 engages with the top end of the lower housing 1. The top end of the torsion spring 4 is designed with a matching engagement structure to the top end of the upper housing 3. When installed in place, its top end will engage in the pre-set slot on the top end of the upper housing 3 to ensure tight connection. Similarly, the bottom end of the torsion spring 4 is also designed with a engagement structure to engage with the top end of the lower housing 1.

[0032] Space for rubbing edges Figure 3 , Figure 4 An airbag 6 is fixedly connected to the front exterior of the lower housing 1. The airbag 6 is made of soft and highly elastic silicone material, which effectively cushions the pinching force on the fingers, preventing discomfort or injury to the user due to excessive pinching force. A connecting tube 7 is fixedly connected inside the lower housing 1. The top end of the connecting tube 7 is fixedly connected to the bottom end of the airbag 6. A balloon 8 is fixedly connected to the rear side of the lower housing 1. The connecting tube 7 is made of medical-grade rubber material, which has good flexibility and excellent sealing performance. The end of the connecting tube 7 away from the airbag 6 is fixedly connected to the rear end of the balloon 8. The connecting tube 7 is fixedly connected inside the lower housing 1, with its top end tightly connected to the bottom end of the airbag 6 and the other end fixedly connected to the rear end of the balloon 8, thus forming a complete inflation channel.

[0033] The rear end of the balloon 8 is equipped with a one-way valve 9, and a spring plate 10 is fixedly connected inside the balloon 8. When the user presses the balloon 8, the air inside the balloon 8 is squeezed out and flows into the airbag cushion 6 through the connecting tube 7; when the user releases the balloon 8, the spring plate 10 takes effect and helps the balloon 8 quickly return to its original shape so that it can be inflated again.

[0034] The top of the balloon 8 is equipped with an adjustment component for deflating the airbag 6. The adjustment component includes an hourglass tube 11, which is externally fixed to the middle of the top of the balloon 8. A piston 12 is movably connected inside the hourglass tube 11. The piston 12 is made of rubber material that fits tightly against the inner wall of the hourglass tube 11. By moving the piston 12 up and down, the user can precisely control the release rate of the gas in the airbag 6, thereby adjusting the pressure of the airbag 6 to meet the different users' needs for finger gripping force.

[0035] refer to Figure 1 , Figure 5 The front side of the upper housing 3 is fixedly connected to a first ring buckle 13, and the rear side of the upper housing 3 is fixedly connected to a second ring buckle 14. The first ring buckle 13 is fixedly connected to the front side of the upper housing 3, and the second ring buckle 14 is fixedly connected to the rear side of the upper housing 3. Both are made of sturdy plastic material and have smooth edges. The second ring buckle 14 consists of two rings.

[0036] The first loop 13 and the second loop 14 are provided with Velcro straps 15. The Velcro straps 15 are fitted over the outside of the lower housing 1. The Velcro straps 15 can pass smoothly through the first loop 13 and the second loop 14 and wrap around the outside of the lower housing 1. In use, after the user wraps the Velcro straps 15 around the lower housing 1, the hook and loop sides of the Velcro are glued together to securely fix the pulse oximeter finger cot.

[0037] A connecting line 16 is provided at the end of the upper housing 3 away from the central axis 2. The function of the connecting line 16 is to transmit the data detected by the detector 5 to an external data processing and display device so that medical staff or users can intuitively obtain the measurement results.

[0038] Working principle: When in use, the lower housing 1 and the upper housing 3 are pressed to compress the torsion spring 4 and fold, thereby opening the opening between the upper housing 3 and the lower housing 1. At this time, the user's finger is placed, and the lower housing 1 and the upper housing 3 are released, so that the detector 5 fits against the patient's finger for measurement. Finally, the hook and loop tape 15 is pulled tight through the surrounding hole and overlapped onto the surface of the hook and loop tape 15, so that the hook and loop side of the hook and loop tape 15 is bonded to the hook and loop side to cover the outside of the finger clip and prevent the finger clip from falling off when worn.

[0039] In addition, the airbag 6 of the finger clip is connected to a connecting tube 7. The user can press the balloon 8 to draw in external air through the one-way valve 9 and inflate the airbag 6 into the connecting tube 7. This allows the airbag 6 to squeeze and wrap around the user's finger, helping fingers of different sizes fit the detector 5 and increasing the accuracy of the measurement data.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
