Description

Protective film replacement device for infant electronic weighing scale

Technical Field

The utility model belongs to the technical field of electronic scales for experience of newborn infants, and particularly relates to a protective film replacement device for an electronic weighing scale for infants.

Background

In the regular physical examination of newborn infants, weight and height are important parameter indexes for evaluating whether the newborn infants are healthy or not. The measurement of the two indexes is generally completed by using an infant electronic scale purchased uniformly by a hospital. At present, an infant electronic scale adopted in a department of academy is an electronic scale with a tray on a base, a sliding rod with scales is arranged on the base on one side of the tray, and a movable baffle is arranged on the sliding rod. Because of the dual function of measuring weight and height simultaneously, the electronic scale is more commonly used in the weight and height projects of newborn infants.

According to the electronic scale, the utility model patent with the publication number of CN216559304U discloses an infrared electronic scale for baby height, and the electronic scale disclosed in the publication is basically consistent with the electronic scale used at present, but has no Y-shaped elastic protective belt for restraining a baby and no infrared measuring instrument electronic sensing equipment for assisting in measuring the height, and the specific structural shape is shown in the electronic scale in fig. 7.

When the electronic scale is used for measurement, a nursing staff firstly uses one hand to prop the head of the baby against the fixed plate of the tray, and the other hand moves the movable baffle to prop against the feet of the baby, so that the height of the baby can be measured according to the scales corresponding to the baffle; the weight of the baby is changed by collecting the gravity according to the weighing sensor at the bottom of the tray and uploading the gravity to the data processor for calculation, and the display panel displays the obtained data of the weight of the baby.

However, in the above measurement process, the infant generally wears clothes to measure, in this case, there is no error in the measured height data basically, but there is a certain error in the measured weight data, which is mainly because the clothes worn by the infant are different each time the infant experiences, so that the measured weight of each time is not the net weight of the infant. Later, we propose an infant naked body to solve the problem of inaccurate weight measurement. However, in the implementation operation, one electronic scale needs to measure all newborn infants in the whole department, and because the skin of the newborn infants is tender and certain secretion is in contact with the tray of the electronic scale to easily cause cross infection, sterilization work needs to be performed on the surface of the tray of the electronic scale before and after each measurement, so that unnecessary cross infection is avoided. This seemingly small disinfecting operation, but for many newborns, the disinfecting effort is not easy and is relatively cumbersome. In addition, if a nurse forgets the disinfection operation in the office, nursing adverse events are likely to be caused, and skin diseases of newborn infants are also likely to be caused.

The handle driving mechanism 4 rotates to roll the contaminated protective film 20 onto the reel 10 in the recovery reel box 3, and simultaneously pulls out a new protective film 20 and covers the tray 18, thereby realizing the replacement of the protective film 20.

Example two

In order to prevent the used protective film from turning around when placed on the tray when the infant is placed, the protective film further causes contamination to come into contact with the skin of the infant's body. In the first embodiment, a ratchet unidirectional control mechanism is arranged in the shell 401, the ratchet unidirectional control mechanism comprises a ratchet 13 fixedly connected to the connecting pin shaft 402, a stopping block 14 corresponding to the ratchet 13 is rotationally connected in the shell 401, a compression spring 15 connected with the stopping block 14 is fixedly connected in the shell 401, and the compression spring 15 is used for ensuring that the stopping block 14 is meshed with gear teeth of the ratchet 13, so that unidirectional rotation of the scroll 10 is limited. The ratchet unidirectional control mechanism is used for limiting the reel 10 in the recovery reel box 3 to reverse, so as to prevent the polluted protective film 20 from retreating to the upper side of the tray 18.

Example III
