Description

Technical Field

[0001] The invention relates to sensor measurement, pediatrics and child health care, and in particular to a method for accurately measuring the state of anterior fontanelle and a matching device. Background Art

[0002] The fontanelle is a gap formed when the skull of an infant is not completely closed. It is mainly divided into the anterior fontanelle and the posterior fontanelle. This is a normal physiological phenomenon. The posterior fontanelle is usually very small or already closed at birth, and will close naturally within 6 to 8 weeks after birth at the latest. In contrast, the anterior fontanelle is about 1.5 cm to 2.5 cm wide at birth. As the baby grows, the anterior fontanelle will also increase with the development of the brain and the increase of the head circumference. Starting from 6 months, as the skull gradually ossifies, the anterior fontanelle will gradually shrink again, and generally close between 1 and 1.5 years old, and in a few cases, it may be delayed until 3 years old.

[0003] Under normal circumstances, the anterior fontanelle is slightly sunken inward. However, in cases of severe dehydration or severe malnutrition, the anterior fontanelle will be significantly sunken; if there is increased intracranial pressure, the anterior fontanelle may bulge. In addition, the temperature of the anterior fontanelle usually reflects the body temperature of the infant and the temperature inside the brain. In the case of fever or diseases such as meningitis, the temperature of the anterior fontanelle area may also rise. Occasionally, you can also feel a slight pulsation in the anterior fontanelle, which is related to the pulsation of blood vessels in this area.

[0004] The status of the anterior fontanelle (including size and closure time) is crucial for monitoring children's brain health. Early or late closure may be a sign of potential problems. Traditionally, doctors estimate the condition of the anterior fontanelle by palpation. This method is direct but not accurate and relies on the doctor's experience. There are currently some tools designed specifically for measuring the size of the anterior fontanelle, such as using a specific measuring ruler. Although this has improved accuracy, it still faces challenges in actual operation, especially requiring the child to remain still. For inexperienced doctors, it is difficult to correctly identify abnormal anterior fontanelle status, which may lead to misdiagnosis or missed diagnosis. Medical staff in non-professional fields do not have enough knowledge of how to accurately assess the anterior fontanelle and its association with certain diseases, which can easily lead to diagnostic errors. For example, the distance between two vertices is mistakenly used instead of the correct length of the line connecting the midpoints of two pairs of sides as a measurement standard, which leads to misunderstandings about the size of the anterior fontanelle and even inappropriate medical decisions based on this, such as misjudging calcium or vitamin D deficiency and giving inappropriate treatment. Therefore, improving the professionalism and accuracy of anterior fontanelle assessment is of great significance to ensuring the healthy growth of infants and young children. Summary of the invention

[0005] The present invention aims to solve the defects of the prior art and provide a method and a supporting device for accurately measuring the state of the anterior fontanelle. The method is suitable for clinical environments to assist doctors in more accurately determining the state of the anterior fontanelle of infants and young children, such as size and tension; it is also suitable for family use to help parents monitor the development of the anterior fontanelle of infants and young children.

[0006] To achieve the above object, the present invention adopts the following technical solution, a method for accurately measuring the state of anterior fontanelle, comprising the following steps:

[0007] S1. Detect the size of the anterior fontanelle using an anterior fontanelle size detection sensor, which can sense pressure changes; calculate and convert voltage values ​​according to sampling signals of the anterior fontanelle size detection sensor to obtain the length of the anterior fontanelle.

[0008] S2. Fix the fontanelle pulsation rhythm detection sensor in the middle of the infant's fontanelle and draw the fontanelle pulsation waveform (i.e., time-pressure curve) to obtain the fontanelle pulsation frequency and rhythm (by identifying the peak and valley values ​​in the waveform, counting the fontanelle pulsation frequency per unit time, analyzing the regularity of the intervals between adjacent pulsations, and evaluating the rhythm).

[0009] S3. Measure the anterior fontanelle temperature using an anterior fontanelle temperature detection sensor.

[0010] S4. The bregma tension is measured using a bregma tension detection sensor. The bregma tension detection sensor changes the voltage signal according to the pressure and converts it into a mechanical index.

[0011] S5. Convert the signals detected by S1-S5 into corresponding electrical signals through the signal conversion device and output the results.

[0012] Furthermore, S1 specifically includes:

[0013] S1.1. Place the fontanelle size detection sensor close to the baby's head, covering the fontanelle area; ensure that the sensor can accurately sense the pressure changes experienced by the entire strip as it moves.

[0014] S1.2. Slowly move the sensor along the baby's head to record the changes in pressure values ​​at different positions; use the hardness difference between the baby's skull (harder) and the anterior fontanelle (softer) to identify the specific position of the anterior fontanelle.

[0015] S1.3. Convert electrical signals into length information: convert the pressure signal received by the anterior fontanelle size detection sensor into a voltage value (the actual length corresponding to each point is determined by calculating these voltage values).

[0016] S1.4. Based on the continuously read pressure changes, the continuous length changes are obtained, and then the obtained length sizes are integrated to reconstruct the shape of the anterior fontanelle. The length of the line connecting the midpoints of the opposite sides is obtained by calculation to obtain the size of the anterior fontanelle (that is, using geometric principles to further quantify the actual size of the anterior fontanelle, such as area, maximum diameter).

[0017] Furthermore, the detection surface of the anterior fontanelle tension detection sensor that contacts the anterior fontanelle of the infant is set to be a convex surface to better fit the concave shape of the anterior fontanelle of the infant.

[0018] Furthermore, the method also includes using a signal output device to display or print out specific values ​​of the anterior fontanelle size, anterior fontanelle pulsation rhythm, anterior fontanelle temperature and anterior fontanelle tension.

[0019] Furthermore, the bregma size detection sensor, the bregma pulsation rhythm detection sensor, and the bregma tension detection sensor all use flexible sensors (such as the piezoelectric film sensor Picoleaf manufactured by Murata Manufacturing Co., Ltd. TM , thin film pressure sensor FPS6130HT from Changzhou FPS Electronic Technology Co., Ltd.).

[0020] Furthermore, the anterior fontanelle temperature detection sensor adopts a temperature sensor (this function can be achieved through an NTC thermistor, such as the PVC# double-wire NTC thermistor MF52D-10KF3435 of Shenzhen Minchuang Electronics Co., Ltd. and the negative temperature coefficient (NTC) thermistor NCP03XH103D05RL for temperature detection of Murata Manufacturing Co., Ltd.).

[0027] The signal output device includes a result display screen and a printing paper output port.

[0028] Furthermore, the anterior fontanelle size detection device, the anterior fontanelle pulsation rhythm detection device, the anterior fontanelle temperature detection device and the anterior fontanelle tension detection device all include a flexible sensor body and an outer protective cover, and each has an electrical signal input terminal and an electrical signal output terminal.

[0030] Furthermore, the signal conversion device also includes a plurality of signal conversion electrical signal modules, which are used to convert the signals from each detection device into electrical signals.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and beneficial effects of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0041] The present invention uses a sensor detection method to simulate the commonly used health detection devices such as bracelets, and designs a method and supporting device for accurately measuring the state of the anterior fontanelle. Compared with the previous patent (CN215687845U), the present invention has the advantages of faster measurement process, more accurate results, and more comprehensive indicators. The present invention can be used to assist clinical doctors in accurately judging the state of the anterior fontanelle of infants and young children, such as size and tension, and can also be used by families to monitor the development of the anterior fontanelle of infants and young children. The materials used in the device of the present invention are relatively inexpensive, the technology is mature, the structure is simple, and it is easy to achieve.

[0042] like Figure 1-5 As shown, the method for accurately measuring the anterior fontanelle state and the measuring method and principle of the supporting device are as follows:

[0043] 1. First of all, the anterior fontanelle size detection device is a flexible sensor that can sensitively sense pressure changes. After the sensor receives the force signal, it will change the resistance or capacitance of the detector, thereby outputting electrical signals of different sizes. The measured length can be obtained by calculating and converting the voltage value again. The sensor is moved close to the baby's head. The sensor can sense the pressure changes experienced by the entire strip. The difference in hardness between the baby's skull and the anterior fontanelle is used to read the length of the part with less pressure. By continuously reading the pressure changes, continuous length changes are obtained, and then the obtained length is integrated to reconstruct the shape of the anterior fontanelle. The length of the line connecting the midpoints of the opposite sides is calculated to obtain the size of the anterior fontanelle.

[0044] 2. Secondly, the anterior fontanelle pulsation rhythm is also a flexible sensor, which is a triboelectric pressure sensor with an interlocking structure, and can accurately draw the anterior fontanelle pulsation waveform to obtain the number and rhythm of the anterior fontanelle pulsation.

[0045] 3. Secondly, the sensor for measuring the temperature of the anterior fontanelle is a small temperature sensor, which senses the temperature of the baby's anterior fontanelle through a highly precise thermal sensitive element and converts it into an electrical signal, which is then converted into a specific temperature through calculation.

[0046] 4. Secondly, the sensor for measuring the tension of the anterior fontanelle is also a flexible sensor. Because the normal anterior fontanelle of infants is mostly slightly concave (slightly lower than the surface of the skull), the surface of the sensor is designed to be convex. The sensor is fixed in the middle of the anterior fontanelle of infants and young children. The anterior fontanelle will exert pressure on the sensor surface, change the voltage signal of the sensor, and then calculate and convert it into a mechanical index.

[0047] 5. Finally, the signal output device will output in the form of "fontanelle size X cm*X cm, fontanelle pulsation rhythm X times / minute, fontanelle temperature X℃, fontanelle tension X mN", where X represents the value of the test result.

[0048] The measurement process of the present invention is as follows:

[0049] 1. First, connect the cable to each interface, turn on the power, and click the power button to turn on.

[0050] 2. Secondly, click the fontanelle size detection button, place the fontanelle size detection sensor close to the infant's forehead, hold both ends of the sensor close to the infant's head and move it backward until it moves to the baby's headrest, and click the detection button again to complete the detection.

[0051] 3. Secondly, fix the fontanelle rhythm detection sensor to the middle of the baby's fontanelle, click the fontanelle rhythm detection button, and wait for 30 seconds for the detection to complete.

[0052] 4. Secondly, fix the anterior fontanelle temperature detection sensor in the middle of the baby's anterior fontanelle, click the anterior fontanelle temperature detection button, and wait for 10 seconds for the detection to be completed.

[0053] 5. Secondly, click the fontanelle tension detection button, fix the fontanelle tension detection sensor in the middle of the baby's fontanelle until both ends of the sensor are close to the skull, click the fontanelle tension detection button again, and the detection is completed.

[0054] 6.Finally, click the print result button to output the test results.

[0055] The invention has the characteristics of accurate measurement, easy operation, simple structure, clear principle, mature technology and easy promotion.

[0056] The detection of the present invention only requires placing different sensors on the head of infants for 10 to 30 seconds to complete the detection, and the detection is convenient. The pressure signal or temperature signal is transmitted to the sensor, and the internal resistance or capacitance of the sensor changes to be converted into an electrical signal, and then the electrical signal is converted into a specific index value after calculation again, and the principle is clear.

[0057] The present invention achieves the purpose of quickly and accurately measuring the state of the anterior fontanelle by placing the sensor at the anterior fontanelle of the infant, and makes the results easy to understand through the output module. The device structure is simple and easy to promote. It innovatively combines the achievements in the field of sensors with existing clinical practice problems, and proposes a method for accurately measuring the state of the anterior fontanelle of infants based on sensors, which not only ensures feasibility but also solves clinical problems. The present invention can be used to evaluate the state of the anterior fontanelle of infants in a non-invasive, rapid, efficient and accurate manner, and has multiple advantages such as intuitive and easy to use, standardized measurement, homogenized data, and easy promotion.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features therein may be replaced by equivalents. Therefore, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope defined by the claims of the present invention.
