A blood oxygen test finger cuff

Abstract

The utility model discloses a blood oxygen test finger cuff, comprising a finger cuff body, with silicone baffles installed on both sides of the finger cuff body, a detachable structure between the silicone baffles and the finger cuff body, a magic tape connected to the lower end surface of the finger cuff body via Velcro, and a slot structure provided on the upper end surface of the finger cuff body, the magic tape wrapped around the outer surface of the finger cuff body and tightly connected to the slot structure. The utility model adopts a fully silicone wrapping method, providing a comfortable fit with the patient's finger during use. The wide-top, narrow-bottom structure is more ergonomic. The strap-type binding can be adjusted according to the size of the finger, preventing excessive tightening from compressing the finger capillaries and excessive looseness from causing data distortion during photoelectric collection. The conveniently installed and fixed light baffle can effectively isolate the influence of external light on red light and infrared light.

Description

Technical Field

[0001] This utility model relates to a blood oxygen testing finger sleeve. Background Technology

[0002] Real-time monitoring of human blood oxygen saturation uses a D / A digital-to-analog converter to control the alternating illumination of LED and PD dual light sources. An optical frequency converter receiver is used as a sensor to convert the light intensity signal into a frequency signal, which is directly sent to a microcontroller for acquisition. The result is calculated based on the principle of reflection.

[0003] Currently available pulse oximetry testing finger sleeves suffer from poor installation and fixation, resulting in measurement accuracy errors and instability in pulse oximetry data. Therefore, it is necessary to develop a new type of pulse oximetry testing finger sleeve to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pulse oximetry testing finger sleeve to solve the problem mentioned in the background art that the pulse oximetry testing finger sleeves currently on the market have poor installation and fixation effects, resulting in measurement accuracy errors and poor stability of pulse oximetry test data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blood oxygen testing finger sleeve, comprising a finger sleeve body, silicone baffles installed on both sides of the finger sleeve body, the silicone baffles and the finger sleeve body being detachable, a Velcro strap connected to the lower surface of the finger sleeve body via Velcro, a slot structure provided on the upper surface of the finger sleeve body, the Velcro strap wrapping around the outer surface of the finger sleeve body and tightly fitting and connecting with the slot structure.

[0006] Preferably, the lower end of the silicone baffle is provided with a locking tab.

[0007] Preferably, the finger sleeve body is provided with an upper clamp and a lower clamp.

[0008] Preferably, the lower end surface of the upper clamping plate and the upper end surface of the lower clamping plate are both provided with clamping groove structures.

[0009] Preferably, the surface of the lower clamping plate is provided with a fitting groove.

[0010] Preferably, the fitting groove and the locking piece are connected accordingly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a fully silicone-wrapped design, providing patients with a comfortable fit around their fingers during use. The top-wide, bottom-narrow structure is more ergonomic, and the strap-style binding can be adjusted according to finger size to prevent excessive tightness from compressing capillaries or excessive looseness from causing data distortion during photoelectric acquisition. The easily installed and fixed light-blocking plate effectively isolates external light from affecting red and infrared light. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4 The present invention provides an embodiment of a blood oxygen testing finger sleeve, comprising a finger sleeve body 8, silicone baffles 6 installed on both sides of the finger sleeve body 8, the silicone baffles 6 and the finger sleeve body 8 having a detachable structure, a Velcro strap 5 connected to the lower end surface of the finger sleeve body 8 by Velcro 4, a slot structure 1 provided on the upper end surface of the finger sleeve body 8, and the Velcro strap 5 wrapping around the outer surface of the finger sleeve body 8 and tightly fitting and connecting with the slot structure 1.

[0020] Furthermore, a locking tab 7 is provided at the lower end of the silicone baffle 6.

[0021] Furthermore, the finger sleeve body 8 is provided with an upper clamping plate 2 and a lower clamping plate 10 respectively.

[0022] Furthermore, the lower end surface of the upper clamping plate 2 and the upper end surface of the lower clamping plate 10 are both provided with clamping groove structures 3.

[0023] Furthermore, the surface of the lower clamping plate 10 is provided with a fitting groove 9.

[0024] Furthermore, the fitting groove 9 and the locking piece 7 are connected accordingly.

[0025] Working principle: During use, silicone baffles 6 are installed on both sides of the finger sleeve body 8. The silicone baffles 6 and the finger sleeve body 8 are detachable. The lower surface of the finger sleeve body 8 is connected to a Velcro strap 5 via Velcro 4. The upper surface of the finger sleeve body 8 is provided with a slot structure 1. The Velcro strap 5 wraps around the outer surface of the finger sleeve body 8 and fits tightly with the slot structure 1. By clamping the patient's finger in the slot structure 3 between the upper clamp 2 and the lower clamp 10, the finger sleeve body 8, being fully silicone-wrapped, provides the patient with a comfortable fit to the finger during use. The wide-at-the-bottom, narrow-at-the-bottom structure is more ergonomic. The Velcro strap 5 and Velcro 4 can be used to wrap and fix the outside of the finger sleeve body 8. The strap binding can be adjusted according to the size of the finger to prevent it from being too tight and compressing the capillaries of the finger, or too loose and causing data distortion during photoelectric acquisition. The lower end of the silicone baffle 6 is provided with a locking piece 7, and the surface of the lower clamping plate 10 is provided with a fitting groove 9. The fitting groove 9 and the locking piece 7 are connected accordingly. The silicone baffle 6, which is easy to install and fix, can effectively isolate the influence of external light on red light and infrared light, and has the advantage of easy installation and fixation.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
