Description

Technical Field

[0001] The present invention relates to a medical auxiliary appliance, in particular to a neonatal gestational age corrector, which is used to evaluate the severity of the disease of premature infants during the treatment process. Background Art

[0002] In the process of premature infant rescue, the corrected gestational age of premature infants is particularly important, and it is of great value to the growth and development of various organs of premature infants. During hospitalization, the corrected gestational age can be used to assess the severity of the disease, such as bronchopulmonary dysplasia. The corrected gestational age is one of the important assessment factors, and it is necessary to combine the corrected gestational age to assess and determine the time to stop follow-up. Therefore, clinical medical staff need to understand the corrected gestational age of premature infants every day.

[0003] At present, the corrected gestational age of premature infants is a project that neonatal medical staff must master. During the clinical process, paper records or computer records are used, and medical staff cannot understand the corrected gestational age of the infant at a glance. It takes time to query the corrected gestational age value, which affects work efficiency. Therefore, the research and development of a special premature infant gestational age corrector that can quickly operate and record and intuitively reflect the corrected gestational age value has become an urgent problem to be solved. Summary of the invention

[0004] In view of the above problems, the present invention provides a neonatal gestational age corrector, which is installed on the incubator of the patient, is convenient for medical staff to operate and record, and can intuitively reflect the corrected gestational age value, thereby avoiding the need for medical staff to reduce query time and improving work efficiency.

[0005] The technical solution of the present invention is: a neonatal gestational age corrector, comprising an inner and outer disk and a through hole in the center, the inner disk is radially provided with inner and outer circles of day numbers 0-6 and gestational week numbers 24-39 respectively; a day reading hole and a gestational week reading hole corresponding to the day numbers 0-6 and gestational week numbers 24-39 on the inner disk are respectively provided on the same center line of the radial direction of the outer disk and the central through hole; after the inner and outer disks are overlapped, a pin is inserted into the through hole to connect them into a relative rotating body; a radial end of the outer disk has an arc-shaped notch.

[0006] In the present invention, the inner and outer disks are disks of equal diameter, with a diameter of 100 mm.

[0007] In the present invention, the inner and outer trays are made of plastic material or cardboard material.

[0008] In the present invention, an adhesive layer is provided on the back of the inner plate.

[0009] In the present invention, a shifting protrusion is provided at the radial end of the outer disk.

[0010] The beneficial effects of the present invention are: by using a specially designed neonatal gestational age corrector, which is pasted or hung outside the incubator of the child, and the numbers on the corrector are rotated daily, the corrected gestational age mark is eye-catching and clear at a glance, which reduces the query time of medical staff and improves work efficiency. At the same time, it is convenient for medical staff to more clearly assess the degree of the child's disease. In addition, the neonatal gestational age corrector has a simple design and is easy to operate. It can be completed by manually rotating the disk, and the corrected gestational age mark is accurate and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a view of the present invention; Figure 2 yes Figure 1 External disk view; Figure 3 yes Figure 1 Inner disk view; Figure 4 yes Figure 1 Another structural embodiment of the outer disk. DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] See Figures 1 to 3 The illustrated neonatal gestational age corrector has an inner disk 6 and an outer disk 1, wherein the inner disk 6 and the outer disk 1 are disk bodies of equal diameter, and the diameter of the inner disk 6 and the outer disk 1 is 100 mm. The inner disk 6 and the outer disk 1 are provided with an outer disk through hole 4 and an inner disk through hole 9 at their central parts, respectively. After the inner disk 6 and the outer disk 1 are overlapped, a pin 5 is inserted through the outer disk through hole 4 and the inner disk through hole 9 to connect them into a relative rotating body. In this embodiment, the gestational age numbers 24-39 and the number of days 0-6 are arranged radially on the inner and outer diameters of the inner disk 6. The gestational age reading hole 2 and the number of days reading hole 3 are provided at positions of the outer disk 1 radially parallel to the outer disk through hole 4 at the center, respectively, which can read the gestational age numbers 24-39 and the number of days 0-6 on the inner disk 6. Therefore, when in use, the inner disk 6 is pasted on the incubator through the adhesive layer provided on the back side, and the outer disk 1 is rotated so that the gestational week reading hole 2 and the day reading hole 3 on the outer disk 1 correspond to the gestational week numbers 24-39 and the day numbers 0-6 on the inner disk 6 respectively, and the numbers are read on the gestational week reading hole 2 and the day reading hole 3 (the words "week" and "day" are marked under the gestational week reading hole 2 and the day reading hole 3).

[0014] In the above, a position of the outer disk 1 has an arc-shaped notch A in the radial direction, so that the outer disk 1 is in a semi-enclosed state as a whole. The arc-shaped notch A can display the gestational age number 8 and the day number 7 on the inner disk 6, making it convenient to view the position of the numbers.

[0015] In the above, the inner and outer plates are made of plastic material or cardboard material, and the gestational age numbers 24-39 and the days 0-6 on the inner plate are printed on the plate.

[0016] In the above, the back side of the inner plate 6 is provided with an adhesive layer.

[0017] In the above, the outer plate 1 is made of cardboard. When in use, the outer plate 1 is pressed and the outer plate 1 is rotated in the reverse direction.

[0018] See Figure 4 Given Figure 1 Another structural embodiment of the outer disk. Figure 2 The invention has made corresponding improvements on the basis of the structure. That is, a toggle protrusion 10 is provided at one radial end of the outer rotating disk 1. When in use, according to the recording requirements, the toggle protrusion 10 is rotated in the counterclockwise direction, and the gestational age of the newborn is recorded through the gestational week reading hole 2 and the day reading hole 3 on the outer rotating disk 1.

[0019] In the above, the outer disk made of plastic material can also be provided with the shifting protrusion 10 .

[0020] How to use: The corrector is pasted and fixed on the incubator of the patient, as shown in Figure 1. If the fetus is corrected to 24 weeks and 6 days, just rotate the gestational week reading hole 2 and the day reading hole 3 on the outer disk 1 to correspond to the 24 on the outer diameter of the inner disk 6 and the number 6 on the inner diameter (that is, the numbers corresponding to the gestational week and the number of days). The words "week" and "day" are marked below the gestational week reading hole 2 and the day reading hole 3, and the two circles of numbers can be rotated and adjusted at will. The method of calculating the corrected gestational age is seven days per week, and the whole week is made up according to the number of days after premature birth, and the rest is + a few days. For example: the premature baby is born with a gestational age of 28+3 weeks and 82 days after birth, then the corrected gestational age is weeks = 28+(82+3) / 7 (rounded) = 28+12 = 40 weeks; days = (82+3)-12x7=1 day, then the corrected gestational age of this premature baby is 40+1 weeks. The neonatal gestational age corrector is simple and convenient to use, and the corrected gestational age is eye-catching and clear, which not only facilitates clinical diagnosis and treatment needs but also improves work efficiency.

[0021] Function of gestational age corrector: 1. According to the corrected gestational age after birth, the weight, height, and head circumference of premature infants can be evaluated and compared with the percentiles of newborns of the same gestational age. Extrauterine growth retardation can be evaluated. For example, when to switch to breastfeeding depends on the growth curve, not the weight.

[0022] 2. During hospitalization, the corrected gestational age can be used to assess the severity of the disease. For example, for bronchial dysplasia, the corrected gestational age is one of the important assessment factors. For retinopathy of prematurity, the corrected gestational age should be combined to assess and determine the time to stop follow-up.

[0023] 3. Premature infants’ cranial MRI also needs to be evaluated in combination with the corrected gestational age. Apgar scores after birth and neurological evaluation during early hospitalization also need to be closely combined with the corrected gestational age.

[0024] 4. After premature babies are discharged from the hospital, they also need to be evaluated and intervened according to the corrected gestational age. Height, weight, head circumference, motor development and intellectual development, including intelligence tests and neuromotor examinations, must be accurately evaluated and judged according to the corrected age.
