Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing scale technology, and in particular to a seated weighing scale. Background Technology
[0002] Ascites is a common complication in the progressive stage of liver diseases such as cirrhosis. Patients experience significant abdominal swelling and tightness due to a large amount of fluid accumulation in the abdominal cavity, often accompanied by symptoms such as weakness, lower limb edema, and difficulty in movement. Their physical function and activity level decline significantly, requiring long-term monitoring of weight changes to assess the regression or progression of ascites and provide crucial information for adjusting clinical treatment plans. Currently, the weighing equipment used clinically and at home mainly includes standing scales and conventional sitting scales. However, standing scales require patients to stand to complete the weighing process. Ascites patients experience abdominal swelling, which leads to instability of the center of gravity and insufficient lower limb support, making them prone to falling when standing. Furthermore, the abdominal muscles need to compensate for the lack of upright posture during standing, which may stretch the tight abdominal wall, aggravate abdominal distension and pain, and even induce discomfort related to a sudden increase in abdominal pressure, thus failing to meet the patient's need for safe weighing.
[0003] To accommodate patients with limited mobility, conventional seated weighing scales have emerged. However, existing seated weighing scales still have significant drawbacks: the core structure of these devices is mostly a combination of a seat and base at a fixed height. Patients need to actively bend forward and lift their legs to sit, requiring abdominal muscles to engage in the process to stabilize the upper body's center of gravity. Furthermore, the bending motion directly pulls on swollen areas of the abdomen, leading to increased abdominal pressure and pain. Although some seated weighing scales have added armrests, these are only used to assist in getting up and cannot provide effective support for the patient's upper body during the sitting process, still making it difficult to avoid the active exertion of abdominal muscles. At the same time, existing seated weighing scales do not have posture guidance structures designed for the physical characteristics of patients with ascites. After sitting down, patients are prone to continuous abdominal pressure due to hunching and shifting posture, which not only affects the weighing experience but may also cause discomfort and lead to patient resistance to weighing, thus affecting the continuity of disease monitoring. Therefore, to address the above problems, we propose a seated weighing scale. Utility Model Content
[0004] This utility model provides a seated weighing scale to solve the aforementioned technical problems.
[0005] The present invention adopts the following technical solution: it includes a load-bearing component, a first telescopic component, and a weighing component. The load-bearing component includes a seat plate and a backrest located above the seat plate. Two first limiting grooves adapted to the human leg are symmetrically opened on the seat plate. The first telescopic component is located below the seat plate and is used to drive the seat plate to rise to contact the patient's buttocks, so that the user can sit on the seat plate, thereby avoiding active abdominal force during sitting. The weighing component is located between the seat plate and the first telescopic component and is used to collect and output the patient's weight data.
[0006] Furthermore, the bottom of the first telescopic member is provided with a base, and a universal brake wheel is provided below the base.
[0007] Furthermore, the base is provided with two second limiting grooves that are aligned with the two first limiting grooves.
[0008] Furthermore, the backrest is provided with handrails at both ends, and a second telescopic member is provided between the handrails and the seat plate for driving the handrails to rise and fall.
[0009] Furthermore, the bottom of the seat plate is provided with a connecting rod, and the bottom of the connecting rod is provided with a placement plate for supporting the feet.
[0010] Furthermore, each of the two handrails is provided with control buttons for controlling the lifting and lowering of the first telescopic member and the second telescopic member.
[0011] The above-mentioned technical solution adopted in this utility model embodiment can achieve the following beneficial effects: by adapting the first limiting groove to the human leg, the patient's legs can be naturally embedded in the first limiting groove when standing, and the first telescopic member drives the seat plate to rise to contact the patient's buttocks. The patient can sit down naturally without actively adjusting his posture, reducing abdominal muscle contraction and external force on the abdomen during sitting, and reducing physical discomfort or fluctuations in condition caused by weighing.

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0016] This utility model provides a sitable weighing scale, including a support component 1. The support component 1 includes a seat 101 and a backrest 102 located above the seat 101. For example, patients with ascites need to monitor their weight frequently. For patients with limited mobility, they can sit on the seat 101, with their body supported by the backrest 102, reducing inconvenience when weighing themselves. To reduce abdominal strain and compression when sitting, two first limiting grooves 2 adapted to the human leg are symmetrically provided on the seat 101. A first telescopic component 3 is located below the seat 101. The patient's legs stand in the two first limiting grooves 2 respectively. Activating the first telescopic component 3... A telescopic component 3 drives the seat plate 101 to rise slowly. When the seat plate 101 contacts the patient's buttocks, the patient's buttocks naturally sit on the seat plate 101, thus avoiding active abdominal exertion during sitting. At this time, the patient's feet can naturally suspend themselves away from the ground. The weighing component 4 located between the seat plate 101 and the first telescopic component 3 can collect and output the patient's weight data. In actual use, a display screen can be added to facilitate data reading by medical staff. In addition, the first telescopic component 3 can be an electric telescopic rod, a hydraulic telescopic rod, or other telescopic structure. This weighing process can directly avoid active bending forward or straddling while sitting, reducing abdominal pressure and improving the weighing experience. The weighing component 4 includes four resistance strain gauge pressure sensors and a data processing module. The four pressure sensors are rectangularly distributed at the four corners of the lower surface of the base plate 101. The sensor model can be HX711 series, which can accurately collect the pressure signal generated by the patient's weight. The data processing module is integrated into the mounting cavity inside the base 5 and is electrically connected to the four pressure sensors through shielded wires. The data processing module can receive the analog signals output by the sensors and convert them into digital signals through the internal AD conversion unit. After filtering, calibration and other processing, accurate weight data is obtained. This is existing technology and will not be discussed in detail here.
[0017] Preferably, the bottom of the first telescopic member 3 is provided with a base 5, and a universal brake wheel 6 is provided below the base 5. The universal brake wheel 6 can be symmetrically distributed at the four corners of the bottom of the base 5. The universal brake wheel 6 can include a roller, a wheel frame and a foot-operated locking mechanism, which can roll smoothly in different ground environments such as wards and homes, and can effectively reduce noise during movement. The foot-operated locking mechanism includes a locking pedal and a brake pad. After the locking pedal is pressed, the brake pad can be tightly fitted with the roller to achieve locking. After locking, the base 5 has no sliding displacement, ensuring the stability of the equipment during the weighing process and avoiding weighing errors caused by equipment shaking.
[0018] Preferably, the base 5 has two second limiting grooves 7 that are aligned with the two first limiting grooves 2. The openings of the first limiting grooves 2 and the second limiting grooves 7 are aligned. When the patient stands, both legs can be inserted through the openings of the first limiting grooves 2 and the second limiting grooves 7. At this time, the first limiting grooves 2 and the second limiting grooves 7 can form circumferential limiting on the legs, which can reduce the left and right deviation of the patient's body during the weighing preparation stage, further reducing the risk of imbalance. In addition, the second limiting grooves 7 can limit the patient's legs from spreading out, so that the seat 101 can contact the buttocks when it rises.
[0019] Preferably, the backrest 102 is symmetrically provided with armrests 8 at both ends. The surface of the armrests 8 can be covered with an anti-slip layer made of rubber, silicone, or other materials to increase the friction when the patient grips the armrests and prevent slippage due to sweaty hands. A second telescopic component 9 is provided between the armrests 8 and the seat plate 101 to drive the armrests 8 to rise and fall. The second telescopic component 9 can be a small electric telescopic rod, hydraulic telescopic rod, etc. Its fixed end can be fixed to the seat plate 101 by bolts, and its movable end is welded to the bottom of the armrests 8. It can be adjusted according to the patient's height and arm length. The height of the handrail 8 can be flexibly adjusted. When the patient needs to sit down, the handrail 8 can be adjusted to a suitable height and gripped firmly to provide reliable support for the upper body and further reduce the need for abdominal exertion. After weighing, the height of the handrail 8 can be lowered to facilitate the patient to get up smoothly or for nursing staff to assist in the transfer. At the same time, for patients with serious conditions who are bedridden, the handrail 8 can be raised to the patient's armpits and placed against the armpits to support the patient when sitting down, reducing the risk of the patient slipping off the seat board 101 and improving the safety of weighing.
[0020] Preferably, each of the two handrails 8 is provided with a control button 12 for controlling the lifting of the first telescopic component 3 and the second telescopic component 9. For example, the left handrail 8 is provided with a button for lifting the first telescopic component 3, and the right handrail 8 is provided with a button for lifting the second telescopic component 9. The buttons are designed with a convex surface to facilitate blind operation by patients or caregivers. All control buttons 12 are electrically connected to the main control module inside the device, and can accurately receive button signals and control the operating status of the corresponding first telescopic component 3 or second telescopic component 9.
[0021] Preferably, the bottom of the seat plate 101 is provided with a connecting rod 10, which is located between two first limiting grooves 2. The connecting rod 10 can be made of stainless steel and has good load-bearing performance. The bottom of the connecting rod 10 is provided with a foot support plate 11. When the patient sits down, the patient's feet can be placed naturally on the foot support plate 11 to avoid muscle tension caused by the legs being suspended. At the same time, the foot support plate 11 can provide support for the legs, further improving the stability of the sitting posture and ensuring the accuracy of the weighing data. In actual use, anti-slip pads made of rubber, silicone or other materials can be set on the foot support plate 11 to increase the adhesion of the feet.
[0022] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
