Detailed Description
The invention is described in further detail below with reference to fig. 1 and 2:
Taking four-wheeled sickbed and bedridden patients as weighing objects for example, the medical portable weighing device comprises a singlechip 3 and four weighing tables 8. The four weighing platforms 8 are in signal communication with the single chip microcomputer 3 through cables, the four weighing platforms 8 respectively correspond to four wheels of a sickbed, and after the four wheels of the sickbed are respectively pushed onto the four weighing platforms 8 to form a support, weighing information is transmitted to the single chip microcomputer 3, and a final weighing result is obtained through operation of the single chip microcomputer 3.
In order to facilitate the four wheels of the sickbed to be smoothly pushed into the four weighing platforms 8 respectively, the weighing platforms 8 are designed to comprise a dustpan-shaped weighing platform body and a gravity sensor 4 embedded on the weighing platform body. The dustpan-shaped weighing platform body is divided into an opening end 1 and a volume end 2 according to space structure distribution, the opening end 1 is inclined and has a slow gradient, and the inclination angle is not more than 10 degrees, so that a sickbed can be conveniently pushed in. In order to smoothly introduce the wheel into the open end 1 of the weighing platform body, the wheel is prevented from being skewed on the open end 1 and the volume end 2, and the accuracy of pushing in positions and the weighing effect are prevented from being influenced. In this example, the inner bottom surfaces 5 of the open end 1 and the volume end 2 are designed to be circular arcs, and the bottommost ends of the circular arc inner bottom surfaces 5 are respectively distributed in the central line direction of the open end 1 and the volume end 2, and the circular arc inner bottom surfaces 5 of the open end 1 and the volume end 2 are mutually communicated. When the wheels of the sickbed enter the dustpan-shaped opening end 1, the wheel surface is naturally introduced to the bottommost end of the circular arc-shaped inner bottom surface 5, namely, the center line direction of the opening end 1, so that the wheels and the weighing platform form an automatic alignment effect, and the alignment problem of the pushing process of the wheels is solved. When the wheels enter the volume end 2, the wheels are guided and stopped in the direction of the bottommost end of the circular arc bottom surface of the volume end 2 under the influence of the circular arc bottom surface, the rims are not contacted with the end surfaces on two sides of the volume end 2, and the accuracy and the reliability of the parking positions of the wheels are ensured. The gravity sensor 4 is arranged on the circular arc bottom surface of the volume end 2, the surface of the gravity sensor 4 is kept horizontal, and the wheels of the sickbed with accurate position parking are just vertically stopped on the weighing surface of the gravity sensor 4, so that the weighing accuracy is ensured.
In order to avoid that the rim of the sickbed wheel is contacted with the rear end surface of the volume end 2 after being pushed into the volume end 2, in the embodiment, a notch 9 is further arranged on the rear end surface of the volume end 2 of the dustpan-shaped weighing platform body, the notch 9 corresponds to the surface of the gravity sensor 4, and the rim of the parked sickbed wheel can naturally extend out of the rear end surface through the notch 9, so that the size of the weighing wheel cannot be limited and influenced.
In order to further improve the usability of the weighing platform 8, the position of the dustpan-shaped weighing platform body is prevented from moving when the wheels are pushed into the dustpan-shaped weighing platform body, and the bottom surface of the dustpan-shaped weighing platform body is also provided with a longitudinal friction edge 6. The friction edges 6 can increase the friction effect of the bottom surface and avoid sliding in the stress process of the dustpan-shaped weighing platform body.
To further improve the usability of the weighing platform 8, the stability of the entire weighing platform 8 is increased. In the embodiment, the anti-tilting support legs 7 protruding outwards are further arranged at the position close to the bottom of the rear side of the dustpan-shaped weighing platform body, and the anti-tilting support legs 7 are surrounded at the position close to the bottom of the rear side of the dustpan-shaped weighing platform body in a semi-surrounding mode in a continuous distribution mode. The bottom surface of the anti-tilting supporting leg 7 is kept level with the bottom surface of the dustpan-shaped weighing platform body. The semi-surrounding anti-tilting support leg 7 increases the contact area between the rear side of the dustpan-shaped weighing platform body and the ground, the gravity center of the whole dustpan-shaped weighing platform body can be always kept stable under the matched support of the front-side horn-shaped opening end 1, and the dustpan-shaped weighing platform body can not tilt or tilt in the left, right, front and back directions when being pushed into a sickbed. Of course, the continuously distributed semi-surrounding anti-tilting support legs 7 may be several mutually matched and independent anti-tilting support legs, which are distributed at two ends and/or at the rear end close to the rear side of the dustpan-shaped weighing platform body, and the stability support of the rear side of the dustpan-shaped weighing platform body is completed by utilizing the protruding state of the continuously distributed semi-surrounding anti-tilting support legs.
When the weighing device is specifically used, the four weighing platforms 8 are communicated with the singlechip 3 through cables to finish the initial setting of the singlechip 3 aiming at the use of the four weighing platforms 8; then, the four weighing platforms 8 are respectively placed corresponding to the four wheels of the sickbed, and the open ends 1 of the dustpan-shaped weighing platform bodies are respectively positioned on the pushing routes of the four wheels; then, pushing the sickbed, wherein four wheels on the sickbed respectively enter the circular arc inner bottom surface 5 of the open end 1, are easily guided to the bottommost end of the inner bottom surface of the open end 1 under the guidance of the circular arc inner bottom surface 5, namely the central line position of the open end 1, smoothly enter the volume end 2 on a channel formed by the mutually communicated circular arc inner bottom surfaces 5 of the open end 1 and the volume end 2, and easily stay above the gravity sensor 4 under the guidance of the circular arc bottom surface; finally, after the wheels are locked by the locking device on the wheels, the weighing information of the gravity sensors 4 at the corresponding four positions can be read by operating the single chip microcomputer 3, the whole weight of the sickbed and the patient on the sickbed can be obtained after calculation, the weight of the patient can be obtained after the weight of a single sickbed is removed, and the monitoring of the weight of the patient is completed.
In the process, the bottom surface of the dustpan-shaped weighing platform body is provided with the longitudinal friction edges 6, so that the friction force of the bottom surface of the dustpan-shaped weighing platform body can be effectively enhanced, and the whole dustpan-shaped weighing platform body is prevented from moving along the thrust direction when being pushed into a sickbed. Simultaneously, the outwards protruding and semi-surrounding anti-tilting support legs 7 can also improve the support area of the rear side of the 'dustpan' -shaped weighing platform body, effectively increase the anti-tilting or anti-tilting effect of the left side and the right side of the whole 'dustpan' -shaped weighing platform body and the anti-tilting effect in the front direction and the rear direction under the auxiliary cooperation of the horn-shaped opening end 1 which is outwards protruding at the front side, and greatly improve the use reliability and the stability of the weighing platform 8.
Of course, if the wheelchair is aimed at in the above process, the singlechip 3 should initially set up for two wheels, and when the wheel with larger spoke is pushed into the volume end 2 of the dustpan-shaped weighing platform body, the opening 9 at the rear end of the volume end 2 can give up the rim of the wheel, so that the weighing process of the larger wheel is not influenced.
Of course, if for special, upright support crutch patients, three weighing platforms 8 can be used for three-point support and weighing of the feet and crutch of the patient, so that the applicability of the whole medical portable weighing device is improved, and the weighing requirements of various clinical patients are greatly facilitated and met.
