Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a reclining measuring device for pediatric use. Background Technology

[0002] The pediatric reclining measurement device is a specialized device used in pediatric health departments to measure various physical indicators of children (such as height, weight, head circumference, and chest circumference).

[0003] Traditional pediatric measurement devices typically only measure a single indicator (such as height or weight) and require the use of other equipment (such as tape measures, measuring tapes, and handheld head circumference measuring straps) to complete a comprehensive assessment. This process is cumbersome, and the cold touch of metal or hard plastic materials can easily cause fear or resistance in children. The fixing straps (such as Velcro) may chafe the skin or compress the body, increasing discomfort. Traditional tape measures require manual winding, and differences in operating techniques (such as tightness) directly affect the results. Given the hyperactive nature of infants and young children, the limited adjustment functions of existing measurement devices necessitate manual intervention to force the infant's cooperation, leading to crying and indirectly affecting the accuracy of the measurement data. Utility Model Content

[0004] To address the aforementioned technical issues, this utility model provides a reclining measurement device for pediatric use. It employs a multi-module combination adjustment mode, enabling the device to actively accommodate the hyperactivity of infants and young children. By using sensors and electronic systems, it reduces human error and places greater emphasis on safety and ease of operation.

[0005] This utility model discloses a pediatric reclining measuring device, comprising a support plate with a soft pad connected to its upper surface. Baffles are fixedly connected to the front and rear ends of the support plate, and side plates are fixedly connected to the left and right sides. The baffles have lifting grooves, and several limiting grooves are formed on one side of each lifting groove. A lifting rod and an adjusting block are sleeved through the lifting groove. The adjusting block is connected to a limiting block via a connecting rod. The lifting rod is slidably connected to multiple sets of sliding rods. One set of sliding rods is slidably connected to an integrated sensor, and another set of sliding rods is slidably connected to a reference plate. Multiple pressure sensors and a flexible sensing strip are installed inside the support plate.

[0006] An adjustment seat is hinged to the bottom of the pallet via a scissor lifting mechanism. The adjustment seat is connected to a base via a slide rail. The adjustment seat is also threadedly connected to a lead screw, and a handle is provided at one end of the lead screw.

[0007] An airbag is connected to one side of the baffle and side plate.

[0008] The integrated sensor is equipped with two infrared emitting probes that emit cross-shaped rays.

[0009] The flexible sensing strip has a built-in flexible strain sensor.

[0010] The reference plate is made of transparent acrylic and has a built-in laser receiver.

[0011] The base is equipped with casters.

[0012] The pallet has a built-in data processing system, including a data receiving module and a remote transmission module, and a display screen is embedded in the side panel connected to the pallet.

[0013] The beneficial effects of this utility model are:

[0014] A lifting groove is created on the tray baffle, and the adjusting block and lifting rod are connected through the lifting groove. The lifting rod has multiple sets of sliding rods, and integrated sensors and a reference plate are installed on the sliding rods. The height of the lifting rod is adjusted and locked through the lifting groove and a limiting groove on one side of the lifting groove. This not only prevents the subject from accidentally slipping during the measurement process, increasing the safety of the measurement process, but also avoids measurement errors caused by the body obstructing the laser emission path. The integrated sensor emits cross rays for precise positioning, while the reference plate has a built-in laser receiver to avoid direct contact, improving measurement accuracy and efficiency. The flexible sensing belt calculates the circumference and measures the head and chest circumference through a built-in flexible strain sensor, reducing errors caused by human operation, reducing reading steps, shortening contact time with the subject, and reducing discomfort. The tray has a built-in pressure sensor to directly measure weight. The data processing system can automatically complete data collection and analysis without manual recording, improving work efficiency. In addition, the height of the tray is adjustable, and combined with the adjustment of the lifting rod, the measurement height is at the optimal viewing angle, conforming to ergonomics, reducing the burden on the staff, and improving work efficiency.

Detailed Implementation

[0024] 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.

[0025] Example 1

[0026] This embodiment presents a reclining measurement device for pediatric use. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The system includes a base 1, which is connected to an adjusting seat 2 via a slide rail. The adjusting seat 2 is hinged to a support plate 5 via multiple sets of scissor-type lifting mechanisms 19. The support plate 5 is equipped with a pressure sensor 17 and a flexible sensing belt 16. The flexible sensing belt 16 has a built-in flexible strain sensor. A soft pad 15 is installed on the upper surface of the support plate 5. A baffle 6 and a side plate 7 are also connected above the support plate 5. A lifting groove 10 is opened on the baffle 6. A lifting rod 8 is directly connected through the lifting groove 10. Adjusting blocks 9 are sleeved at both ends of the lifting rod 8. Limiting blocks 21 are connected to the adjusting blocks 9. The limiting blocks 21 cooperate with several limiting grooves 20 opened on one side of the lifting groove 10 to lock the lifting rod 8 in the vertical direction. The inner sides of both ends of the lifting rod 8 are slotted. Multiple sets of sliding rods 11 slide left and right on the lifting rod 8. An integrated sensor 12 is connected to one set of sliding rods 11, and a reference plate 13 is connected to another set of sliding rods 11.

[0027] When using the measuring device, adjust the height of the lifting rod 8 according to the infant's body size and range of motion. Lift the adjusting block 9 upwards, and the lifting rod 8, which is connected to the adjusting block 9, will rise. The limiting block 21 connected to the adjusting block 9 will slide upwards within the lifting groove 10. When the appropriate height is reached, turn the adjusting block 9 counterclockwise to allow the limiting block 21 to slide into the limiting groove 20 on one side of the lifting groove 10 to lock the height. Correspondingly, when it is necessary to lower the height of the lifting rod 8, turn the adjusting block 9 clockwise to allow the limiting block 21 to disengage from the limiting groove 20 and engage in locking before sliding downwards. By adjusting the height of the lifting rod 8, raising the lifting rod 8 can prevent the subject (especially infants) from accidentally slipping or moving during the measurement process, increasing the safety of the measurement process. At the same time, the sliding rod 11 rises with the lifting rod 8, avoiding obstruction of the infrared emission path of the integrated sensor 12 due to body obstruction, which could lead to measurement failure and reduce measurement errors caused by improper body position. If the height is not suitable, adjust the lifting rod 8 to a suitable height, and slide the slider 11 on the lifting rod 8 to adjust the position of the integrated sensor 12. At this time, the integrated sensor 12 integrates a laser-assisted positioning module and an infrared ranging module. Two sets of infrared emitting probes 1201 emit cross-shaped laser lines. The laser line emitted by the auxiliary positioning module is aligned with the top of the head to complete the calibration. At the same time, slide the other set of sliders 11 to bring the reference plate 13 closer to the sole of the subject's feet. The reference plate 13 is made of transparent acrylic material and has a built-in laser receiver, which can provide real-time feedback on the contact status. After the baffle 6 contacts the body, the laser rangefinder automatically starts and vertically aligns with the center point to complete the height measurement. Laser ranging technology can provide very high measurement accuracy. Combined with laser reception, the measurement can be completed without direct contact with the subject. This is particularly useful when dealing with infants or uncooperative children, reducing anxiety or resistance caused by physical contact and improving work efficiency.

[0028] The flexible sensing belt 16 incorporates flexible strain sensors evenly distributed along the belt body to ensure that overall deformation is captured during stretching. The built-in flexible strain sensors detect the degree of stretching, and the circumference is calculated based on the sensor data to measure head and chest circumference. Compared to traditional manual tape measures, the flexible sensing belt 16 reduces errors caused by individual operating techniques. Made of soft and elastic material, it adapts to different body shapes and ensures that it does not cause discomfort or harm to children when worn. A high-precision pressure sensor 17 is embedded at the bottom of the bed to directly measure weight. The measurement data is automatically collected by the data receiving module built into the support plate 5 and displayed in real time on the display screen 22. It is then directly transmitted to the central processing unit (PC database) via a remote transmission module for immediate analysis and comparison with historical data, helping doctors better understand the child's growth and development.

[0029] Please see Figure 1 , Figure 2 and Figure 6The adjusting seat 2 slides on the base 1 via a slide rail. The tray 5 is hinged to the adjusting seat 2 via a scissor lifting mechanism 19. The adjusting seat 2 is threadedly connected to the lead screw 18. One end of the lead screw 18 is connected to the handle 4. By rotating the handle 4, the lead screw 18 drives the adjusting seat 2 to slide on the base 1. At the same time, the scissor lifting mechanism 19 raises and lowers the tray 5 to adjust its height. In the above-described operation where the lifting rod 8 needs to be raised for specific situations, to avoid inconvenience to the measuring personnel, the height of the tray 5 can be lowered to reduce the doctor's arm raising action, thereby reducing the workload and improving work efficiency. Adjusting the tray 5 to the optimal viewing angle allows equipment such as laser rangefinders to work more accurately, avoiding measurement errors caused by improper positioning. During this process, the airbag 14 connected to the baffle 6 and the side plate 7 can be inflated and deflated to adjust its hardness, playing a buffering role and effectively reducing the impact of collisions or falls, providing additional safety for children. The casters 3 installed at the bottom of the base 1 allow the entire device to move easily, improving the mobility and utilization of the equipment.

These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
