Description

[Detailed description of the invention] The present invention relates to a baby scale, and its purpose is to provide an index display type baby scale that can accurately and quickly display the developmental status of the person to be weighed with simple operation. .

Embodiments of the present invention will be described below based on the drawings. Figure 1 shows the state of baby's development.
This figure shows the configuration of an index display type baby scale in which index display of Rohrer index and Kaup index can be selected. 1 is a weighing part, a basket 1a on which the baby is placed, and a strain gauge that converts the load value received by the basket 1a into an analog signal. The load cell 1b includes an analog-to-digital converter 1d that converts the output of the load cell 1b via an amplifier 1c into a digital signal. Reference numeral 2 denotes a weight register that stores and holds a digital signal from the weighing section 1 for a predetermined period of time in accordance with the load value received by the basket 1a, and a motion detector that detects the balance state by monitoring changes in the digital signal, for example. (not shown)], and a weight value that ensures a certain level of reliability is stored. 3 is a weight display unit that digitally displays the contents of the weight register 2 as a weight value; 4 is an input device for setting the height of the person to be weighed; and a numeric keypad 4a for numeric values, and a numeric keypad 4a for clearing the content entered using the numeric keypad 4a. and a numeric keypad register 4b which is stored and retained until it is instructed. Reference numeral 5 indicates a numeric display unit that digitally displays the contents of the numeric keypad register 4b as height, and 6 indicates the state of growth of the baby in the basket 1a from the weight information and height information output from the weight register 2 and the numeric keypad register 4b, respectively. This calculation unit automatically calculates an index, and is configured to perform calculation processing of the Rohrer index or Kaup index according to the selection operation of the switch 6a. Reference numeral 7 denotes an index display for displaying the calculation results of the calculation section 6 as an index.

For example, the operation is performed as follows. First, the height of the baby to be weighed, which has been measured in advance, is keyed in using the numeric keypad 4a, and then the switch 6a is selected in accordance with the index to be determined according to the baby's age, etc. Here, if the calculation unit 6 is instructed to calculate the Rohrer index, when the baby is placed in the basket 1a and the weight balances, the calculation unit 6
The output is (weight) / (height) ³ × 100 ² However, the unit of weight is [g], and the unit of height is [cm].
The processed signal is automatically output, and the index display 7 shows the growth status of the weighed baby.
The Rohrer index is displayed. On the other hand, when Kaup index calculation processing is selected by the switch 6a, the calculation unit 6 calculates (weight)/(height) ² × 10 However, the unit of weight is [g], and the unit of height is [cm].
The processing is automatically performed, and the instruction display 7
Kaup index can be read.

In this way, by simply inputting the baby's height using the numeric keypad 4a and placing the baby in the basket 1a, it is possible to automatically calculate and display the index in both the Rohrer index and the Kaup index. Therefore, the handler must first read the weight value as in the past, and then based on the obtained weight value (weight value) and the baby's height, read the corresponding index of the baby being weighed. The work of reading the index table and the calculation work based on the read weight values can be omitted, and the desired index can be obtained in a short time. Furthermore, since the desired index can be obtained without reading the body weight as in the conventional method, the reliability of the obtained index is also improved.

In the above embodiment, the calculation section 6 is the switch 6.
Depending on the selection of a, the calculation process of Rohrer index and Kaup
Although the configuration has been described so that both exponent arithmetic operations can be performed, the same effect can be obtained if the configuration is configured to enable at least one of the two exponent arithmetic operations.

As explained above, according to the present invention, an index representing the state of growth can be automatically obtained by the two actions of placing the baby to be weighed on the scale and setting the height determined in advance on the input device. Therefore, the operator can omit the work of reading the weight of the baby to be weighed and reading the index table, etc., and can quickly obtain accurate indexes.
