Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a device for measuring the anterior fontanelle and tension of infants. Background Art

[0002] The fontanelle is a soft tissue area formed when the infant's skull is not completely closed. It is divided into the anterior fontanelle and the posterior fontanelle, which make the infant's skull softer and more adaptable to growth. The anterior fontanelle of an infant is largest at 1 month old, then gradually becomes smaller until it closes at 1.5 to 2 years old. The size, closure time, and tension of the anterior fontanelle are of great significance for monitoring the growth and development of infants and young children and assessing their health status. Correct measurement and recording can help medical staff monitor the risk of related diseases and provide timely intervention and treatment.

[0003] The size of the anterior fontanelle is expressed as the distance between the midpoints of the opposite sides of the rhombus. The commonly used measurement method in clinical practice is: an assistant helps to fix the head of the infant, and when the infant is quiet, the measurer touches the four sides of the anterior fontanelle and uses a soft ruler to measure the length of the line connecting the midpoints of the two opposite sides, and takes the average of three measurements. This method has a large measurement error and also relies on the clinical experience of the measurer. This method has poor measurement stability and leads to inaccurate readings.

[0004] Under normal circumstances, the fontanelle is flat and soft, showing a certain tension and slight expansion. When the surface of the anterior fontanelle bulges, it means that the tension has increased, indicating increased intracranial pressure and requiring immediate medical treatment. Therefore, designing a medical device that can simultaneously measure the size and tension of the anterior fontanelle will more accurately and reliably monitor the growth and development of infants' heads.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-2The device for measuring the anterior fontanelle and tension of infants shown in the figure comprises a monitoring device 1, a voltage conversion module 2, a data collector 3 and a data processing system 4. The monitoring device 1 comprises a disc 5, and a measuring component is arranged on the inner ring wall of the disc 5.

[0021] Specifically, the measurement components include:

[0022] A fixed ruler 6, both ends of which are fixedly connected to the inner wall of the disc 5;

[0023] The rotating ruler 7 is rotatably inserted and connected to the inner ring wall of the disc 5, and the rotating ruler 7 is arranged on the top of the fixed ruler 6.

[0024] Furthermore, a supporting rotating rod 9 is inserted and connected to the middle of the fixed ruler 6 , and the rotating ruler 7 is rotatably sleeved on the outer wall of the supporting rotating rod 9 , and the film sensor 8 is arranged at the bottom end of the supporting rotating rod 9 .

[0025] Furthermore, a squeezing screw 10 for squeezing and positioning the rotating ruler 7 is inserted and connected through the top thread of the supporting rotating rod 9 .

[0026] Specifically, the zero scales of the fixed ruler 6 and the rotating ruler 7 are both set at the connection close to the supporting rotating rod 9.

[0027] Furthermore, the scales of the fixed ruler 6 and the rotating ruler 7 increase from the center to both ends.

[0028] It should be noted that the surface of the disk 5 is marked with various angle scales, and the zero scales on both sides are fixedly connected to the two ends of the fixed scale 6 respectively; the centers of the fixed scale 6 and the rotating scale 7 coincide and are hinged to each other through the supporting rotating rod 9. Through such a setting, the angle between the fixed scale 6 and the rotating scale 7 can be changed arbitrarily, and then through the structural setting of the squeezing screw 10, tightening the squeezing screw 10 during measurement can squeeze the rotating scale 7 downward, so that after the rotation measurement, it can assist in accurate reading by tightening it.

[0029] As a dynamic strain sensor, the thin film sensor 8 is used for monitoring vital signs on the surface of human skin or implanted in the human body. When the piezoelectric polyvinylidene fluoride polymer film of the thin film sensor 8 is stretched or bent, an electrical signal will be generated between the upper and lower electrode surfaces of the film, and will be proportional to the deformation of the stretching or bending. In this solution, the thin film sensor 8 is installed at the bottom end of the supporting rotating rod 9 with the front side facing downward, and the line channel is hidden under the fixed ruler 6 and extends along the ruler axis to the outside of the disc 5.

[0030] A thin film sensor 8 is provided at the bottom end of the disk 5, the communication end of the thin film sensor 8 is electrically connected to the receiving end of the voltage conversion module 2, the transmission end of the voltage conversion module 2 is electrically connected to the receiving end of the data collector 3, the output end of the data collector 3 is electrically connected to the receiving end of the data processing system 4, the data processing system 4 is used for processing electrical signals, and can be connected to a display to display waveform signals.

[0031] It should be noted that the film sensor 8 produces corresponding resistance changes according to the tension of the anterior fontanelle, outputs the corresponding voltage signal through the voltage conversion module 2, and finally is processed by the data collector 3 and the data processing system 4 movement, after which the anterior fontanelle tension waveform can be presented on the computer interface through the electrical signal.

[0032] When using the device, align the center of the disc 5 with the center of the infant's anterior fontanelle and place it in a plane parallel to the anterior fontanelle. Rotate the disc 5 until the scale line of the fixed ruler 6 is parallel to the line connecting the midpoints of one pair of sides of the anterior fontanelle. Rotate the rotating ruler 7 until its scale line is parallel to the line connecting the midpoints of the other pair of sides of the anterior fontanelle.

[0033] Assuming the sum of the scale readings at both ends of the fixed ruler 6 is acm, and the sum of the scale readings at both ends of the rotating ruler 7 is bcm, the measurement result of the anterior fontanelle is:

[0034] acm*bcm(1);

[0035] This is the measurement of the size of the anterior fontanelle;

[0036] When the anterior fontanelle of an infant is obviously bulging and the saturation is too high, the anterior fontanelle tension acts on the thin film sensor 8 at the bottom layer of the disk 5, and the elastic film undergoes compression deformation and produces a corresponding resistance change. The corresponding voltage signal is output through the voltage conversion module 2 to complete the conversion of non-electrical quantity to electrical quantity. After that, after signal collection by the data collector 3 and data processing by the data processing system 4, a tension waveform interface is presented, and the anterior fontanelle tension measurement results and change trends can be directly observed.

[0037] Finally, it should be noted that the above 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 make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
