Abstract
The utility model discloses an automatic weighing device of a newborn radiation board. The automatic weighting device comprises a cantilever type weighting sensor arranged on the lower part of the radiation board, wherein the cantilever type weighting sensor outputs a mV level weak signal to an A/D converter, the output of the A/D converter is connected with the microprocessor, and the microprocessor is connected with a touch control screen for displaying the body weight of the sick newborn. The automatic weighting device is reasonable in structure and good in working performance and the daily body weight of the sick newborn is automatically stored for future review. The display part and the keyboard part are integrated, thus the color electronic touch screen is used to display all the state information of the system at one time, so as to facilitate the clinical reference of the medical care personnel.
Description
Technical field
The utility model relates to a kind of neonate's radiation table automatic Weighing device.
Background technology
Neonate's radiation table is to rescue one of neonatal necessary equipment, in newborn care work, and premature especially, body weight is one of important indicator of the reflection infant state of an illness and as the foundation of dosage.As judge infant PD situation; Measure unbalanced patient for discrepancy, can judge edematous condition; For the diarrhoea patient, observable has or not dehydration; And premature's medication is strictly by body weight accurate Calculation dosage, to reach optimum curative effect, minimal side effect.So premature's Avoirdupois monitoring, for instructing the clinical application treatment, judging that the PD situation is significant.At present, in clinical newborn care, every day, Avoirdupois monitoring was as one of routine care of premature, for common premature, use baby's electronic scales to get final product, but for the critical premature of the state of an illness, especially put radiation table, use the infant of lung ventilator, weigh every day as using the particularly inconvenience of conventional method, need many people's operations, and can be because moving infant, affect the infant state of an illness, even causing the infant lung ventilator to take off pipe, intubate increases the infant misery again, even jeopardize infant life, greatly increase nursing work load and nursing Risk.
The utility model content
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, neonate's radiation table automatic Weighing device of favorable working performance.
Technical solution of the present utility model is:
A kind of neonate's radiation table automatic Weighing device, it is characterized in that: comprise the cantilevered LOAD CELLS that is arranged on radiation table bed body bottom, cantilevered LOAD CELLS output mV level feeble signal is to A/D converter, the output of A/D converter is connected with microprocessor, and microprocessor is connected with the touch screen that shows the infant body weight.
A/D converter is 24 bits serial A/D converter, the △-∑ A/D converter of high integration, performance reaches 24, its chip internal has an extremely low noise chopper-stabilized instrumentation amplifier, its gain may be selected to be 2n (n=0～6), reaches 120 dB at the common-mode rejection ratio representative value of 50 Hz, the inner △ one ∑ modulator that also has 4 rank, follow a digital filter, 10 kinds of alternative output word speed are provided thereafter.
The utility model is rational in infrastructure, favorable working performance.Can be with every daily weight autostore of infant usefulness for from now on review.Show and keyboard portion unites two into one and adopts the color electric touch-screen, can all status informations of display system, make things convenient for the clinical reference of medical personnel.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
A kind of neonate's radiation table automatic Weighing device, comprise the cantilevered LOAD CELLS 2 that is arranged on radiation table bed body (weighing unit) 1 bottom, cantilevered LOAD CELLS output mV level feeble signal is to A/D converter 3, the output of A/D converter is connected with microprocessor 4, shows the infant body weight at electronic touch screen 5 after microprocessor processes.
In order to satisfy the requirement of small-signal measuring accuracy, the A/D converter that adopts aspect ADC is high precision 24 bits serial A/D converter.It is the △-∑ A/D converter of high integration, owing to used charge balance technique, its performance can reach 24.The list of the applications such as very suitable measurement weighing instrument, process control, science and medical treatment/bipolarity small-signal.
Chip internal has an extremely low noise chopper-stabilized instrumentation amplifier, and its gain may be selected to be 2n (n=0～6), has enlarged the signal input range, allows the input of small-signal, has improved the dynamic perfromance of system.Its common-mode rejection ratio representative value at 50 Hz can reach 120 dB, and this is very favourable to detect faint differential voltage signal from high common mode voltage.The inner △ one ∑ modulator that also has 4 rank is followed thereafter a digital filter, and 10 kinds of alternative output word speed can be provided.Utilize inner calibration system (comprising self calibration and system calibration), zero point and the gain slope of ADC transport function can be set, thereby eliminate imbalance and the gain error of system channel.
24 A/D signal is delivered to microprocessor, after treatment in the body weight of touch-control screen display infant 6.Also has radiant panel 7 among the figure.
