Description
Technical Field
The utility model relates to a medical instrument field specifically is an irregular wound girth measuring device of skin.
Background
Currently, area measurement is commonly used as a main method for wound measurement in clinic, but wound growth and healing are shrunk inwards along the edge of the wound, so that the circumference of the wound is important medical data, a convenient measuring tool is not available for measuring the circumference of the wound at present, and the measurement is performed by a wire paying-off method, namely, a wire is wound around the outer edge of the wound for one circle, and then the length of the wire is measured.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides an irregular wound girth measuring device of skin, the effectual current wound girth of having solved of having measured inconveniently, the great problem of error.
The technical scheme includes that the device for measuring the perimeter of the irregular wound of the skin comprises a square vertical rod, a roller is mounted at the lower end of the vertical rod, a first gear located on one side of the vertical rod is coaxially and fixedly mounted on the roller, a second gear located above the first gear and meshed with the first gear is mounted on the vertical rod, a dial is coaxially and fixedly mounted on the second gear, scale marks are evenly distributed on the circumference of the dial, a protruding block is fixed on the side wall of the dial, a button type counter located above the scale is mounted on the vertical rod, the counter is provided with a counting button and a reset button, the counting button is arranged below the counting button, the dial rotates for a circle, and the protruding block can press the counting button once.
The utility model discloses convenient to use, measurement of efficiency is high, and the error is little.

Fig. 4 is a front view of the present invention in use.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
By figure 1 to 4 and give, the utility model discloses a montant 1 of a square, a gyro wheel 2 is installed to the lower extreme of montant 1, 2 coaxial fixed mounting of gyro wheel have one be located montant 1 one side first gear 3, install one on montant 1 be located first gear 3 top and with first gear 3 meshed second gear 4, 4 coaxial fixed mounting of second gear have a calibrated scale 5, the circumference equipartition has the scale mark on the calibrated scale 5, be fixed with a protruding piece 6 on the lateral wall of calibrated scale 5, install a button counter 7 that is located scale side top on montant 1, the counter is equipped with count button 8 and zero clearing button 9, count button 8 is under, calibrated scale 5 rotates a week, protruding piece 6 can press once count button 8.
The vertical rod 1 is provided with an initial position mark 10 positioned outside the dial 5.
The convex block 6 is positioned at the zero graduation line of the dial 5.
The upper end of the vertical rod 1 is connected with a grab handle 11.
The grab handle 11 is obliquely arranged.
The utility model discloses a scale interval on calibrated scale 5 can be the radian scale, also can be the length scale that has converted by the radian scale, and the method of 2 rolling lengths of gyro wheel is converted by the radian of calibrated scale 5 is: multiplying the radian of the dial 5 by the radius of the dial 5, then multiplying by the ratio of the diameters of the roller 2 and the dial 5, and then multiplying by the transmission ratio of the first gear 3 and the second gear 4; after calculation, a proportional constant between the camber value of the dial 5 and the rolling length of the roller 2 can be obtained and recorded as K, and the rolling length of the roller 2 corresponding to one circle of non-rotation of the dial 5 can be calculated and recorded as L.
When the utility model is used, firstly, the reset button 9 of the button type counter 7 is pressed to reset the button type counter 7, then the dial 5 is rotated to align the zero scale line with the initial position mark 10, then the grab handle 11 is held by hand to ensure that the bottom of the roller 2 is contacted with the skin of a patient and keeps a certain pressure, then the roller 2 is pushed along the outer edge of a wound to ensure that the roller 2 rolls for a circle around the wound; the rolling of the roller 2 can drive the first gear 3 to rotate, the first gear 3 rotates to drive the second gear 4 and the dial 5 to rotate, the protruding block 6 presses the counting button 8 once every time the dial 5 rotates for a circle, the button counter 7 counts once, after the counting is finished, the numerical value N of the button counter 7 and the radian value rad of the dial 5 corresponding to the initial position mark 10 are read, and then the rolling length of the roller 2 is obtained according to a formula NxL + radxK, namely the circumference of a wound.
The utility model discloses measure and calculate equal convenient and fast, need not the unwrapping wire operation, improved work efficiency, reduced measuring error simultaneously.
