Description

Technical Field

[0001] This utility model relates to the field of medical product technology, specifically to a home-use fetal heart rate monitor with blood oxygen detection function. Background Technology

[0002] Currently, commercially available ultrasound Doppler fetal heart rate monitors (hereinafter referred to as fetal heart rate monitors) are mainly used to detect fetal heart rate after 9 weeks of pregnancy for fetal screening. If it is desired to obtain maternal physiological parameters such as maternal pulse rate and blood oxygen saturation at the same time, a separate blood oxygen probe is required, which is more troublesome to use. The blood oxygen testing methods are reflective detection and transmissive detection.

[0003] Current fetal heart rate monitors use a reflective pulse oximetry solution. This involves mounting a reflective pulse oximetry module on a hard plastic casing, with a window in the casing for attaching a lens. During pulse oximetry testing, the skin is pressed against the module's transmitting / receiving surface. If the pressure is too tight, the blood vessels on the inner side of the skin in contact with the module will be compressed, causing blood flow obstruction. This weakens the diffuse reflected light received by the module, resulting in inaccurate pulse oximetry readings. Conversely, if the pressure is too loose, light leakage or ambient light contamination can occur, leading to inaccurate data, negatively impacting the user's measurement experience, and hindering product competitiveness.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, this utility model discloses a home-use fetal heart rate monitor with blood oxygen detection function, including a fetal heart rate monitor body 1. The fetal heart rate monitor body 1 is provided with a fetal heart rate detection component, a controller assembly, and a blood oxygen detection component. The fetal heart rate detection component and the blood oxygen detection component are electrically connected to the controller assembly. The blood oxygen detection component includes a pressable elastic connector 2 and a blood oxygen detection component. The pressable elastic connector 2 is provided with a housing connection part 21 and a detection pressable connection part. The blood oxygen detection component is fixedly connected to the pressable elastic connector 2 and is disposed in the detection pressable connection part. The housing connection part 21 is disposed around the pressable elastic connector 2 and is fixedly connected to the fetal heart rate monitor body 1. The fetal heart rate monitor body 1 is provided with a pressable window 11 that cooperates with the detection pressable connection part. The blood oxygen detection component can move up and down in the pressable window 11. The blood oxygen detection component is electrically connected to the controller assembly. The pressable elastic connector 2 can provide elastic force for the blood oxygen detection component when it is pressed.

[0024] By setting up the press-elastic connector 2, the blood oxygen detection component is fixedly connected to the press-elastic connector 2. When the blood oxygen detection component is pressed, it can be depressed downward under the elastic action of the press-elastic connector 2. The elasticity of the press-elastic connector 2 offsets excessive pressing force, avoiding the situation where excessive finger pressing causes serious blockage of blood vessels, which affects the measurement results, thus ensuring the accuracy of the measurement results and improving the user experience.

[0025] The blood oxygen detection component includes a blood oxygen module glass 31 and a blood oxygen detection module 32, with the blood oxygen module glass 31 positioned above the blood oxygen detection module 32.

[0026] The blood oxygen module glass 31 effectively protects the blood oxygen detection module 32.

[0027] The blood oxygen detection component also includes a detection mounting bracket 33, which has a blood oxygen mounting position 331 that cooperates with the blood oxygen detection module 32. The blood oxygen detection module 32 is fixedly mounted on the blood oxygen mounting position 331. The detection pressing connection part is a detection window 221 set on the pressing elastic connector 2. The blood oxygen detection module 32 can cooperate with the detection window 221 to detect blood oxygen. The detection mounting bracket 33 is fixedly connected to the pressing elastic connector 2.

[0028] The mounting bracket 33 facilitates easy assembly with the blood oxygen module glass 31 and the blood oxygen detection module 32.

[0029] Obviously, other methods can be used to replace the method of using the mounting bracket 33 to install and fix the blood oxygen monitoring module. For example, a groove can be directly provided on the detection pressing connection part, and the blood oxygen detection component can be directly placed in the groove. A cable hole is provided in the groove, and the cable of the blood oxygen detection component passes through the cable hole to connect to the controller component electrically. The groove supports and fixes the blood oxygen detection component, which can achieve the same effect as the above solution.

[0030] The testing mounting bracket 33 is provided with multiple first connection holes 332 that cooperate with and are fixed to the pressing elastic connector 2. The testing mounting bracket 33 and the pressing elastic connector 2 are integrally molded by secondary injection molding.

[0031] With the structure of two-stage injection molding, the liquid glue will fill the first connection hole 332 during injection molding, so that the detection mounting frame 33 and the pressing elastic connector 2 are integrally formed, which can effectively ensure the stability of the relative position of the detection mounting frame 33 and the pressing elastic connector 2.

[0032] Obviously, for the setting of the detection mounting bracket 33 and the pressing elastic connector 2 being integrally molded by secondary injection, other methods can be used to fix the detection mounting bracket 33 and the pressing elastic connector 2. For example, the detection mounting bracket 33 and the pressing elastic connector 2 can be fixed with glue, or they can be fixed with screws, or they can be fixed with clips, etc., which can achieve the same effect as the above solution.

[0033] The fetal heart rate monitor body 1 is provided with multiple second connection holes 101 that are fixed to the housing connection part 21. The press elastic connector 2 is integrally molded with the fetal heart rate monitor body 1 by secondary injection molding.

[0034] With the structure of two-stage injection molding, the liquid glue will fill the second connection hole 101 during injection molding, so that the press elastic connector 2 and the fetal heart rate monitor body 1 are integrally formed, which can effectively ensure the stability of the relative position of the press elastic connector 2 and the fetal heart rate monitor body 1.

[0035] Obviously, for the method of fixing the fetal heart rate monitor body 1 and the press elastic connector 2 by secondary injection molding, other methods can be used to fix the fetal heart rate monitor body 1 and the press elastic connector 2. For example, the fetal heart rate monitor body 1 and the press elastic connector 2 can be fixed with glue, or with screws, or with clips, etc., which can achieve the same effect as the above solution.

[0036] The fetal heart rate monitor body 1 has a positioning and mounting step 102 around the pressing window 11. The second connecting hole 101 is located on the positioning and mounting step 102. The housing connecting part 21 is located on the positioning and mounting step 102. The height of the housing connecting part 21 is not higher than the positioning and mounting step 102.

[0037] By setting the positioning and installation step 102, it is convenient for processing personnel to install the pressing elastic connector 2 quickly, improve installation efficiency, and ensure that the shell connection part 21 does not protrude from the surface of the fetal heart rate monitor body 1, making it more integrated in use.

[0038] The pressing elastic connector 2 is shaped like a boss, and the pressing connection part is located on the top of the pressing elastic connector 2.

[0039] By adjusting the shape of the elastic connector 2, the elastic stroke of the press can be effectively increased, preventing it from contacting the internal structure of the fetal heart rate monitor body 1 during pressing and affecting the accuracy of the measurement.

[0040] The fetal heart rate detection device is fixedly installed at the bottom of the main body 1 of the fetal heart rate monitor, and an ultrasonic probe is installed on the fetal heart rate detection device.

[0041] Fetal heart rate can be measured using an ultrasonic probe.

[0042] The controller assembly includes a main control board 4, a speaker assembly 5, a silicone button cover 6, and a power supply battery 7. The main control board 4 is equipped with a display module 41 and multiple button controls 42. The silicone button cover 6 is installed on the button controls 42. The fetal heart rate monitor body 1 is equipped with a display window and button holes that cooperate with the display module 41 and the button controls 42. A protective lens 8 is installed on the display window.

[0043] The horn assembly 5 includes a horn cover and a horn, and the fetal heart rate monitor body 1 is provided with a horn sound outlet 103 that cooperates with the horn.

[0044] This mechanism effectively solves the problem of poor accuracy in existing fetal heart rate monitors that use reflective blood oxygen detection. By using this product structure, the blood oxygen detection component is fixedly connected to the press-fit elastic connector 2. When the blood oxygen detection component is pressed, it can be depressed downwards under the elastic action of the press-fit elastic connector 2. The elasticity of the press-fit elastic connector 2 offsets excessive pressing force, avoiding the situation where excessive finger pressure can cause serious blockage of blood vessels, thus affecting the measurement results. This ensures the accuracy of the measurement results, improves the user experience, and enhances the product's competitiveness.

All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
