Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a wound measuring ruler used to accurately measure the length, width, and area of ​​a wound. Background Technology

[0002] Accurate measurement of trauma is crucial in medical practice. Knowing the size and area of ​​a wound accurately helps doctors develop appropriate treatment plans, assess wound healing, and predict potential complications. Traditional measuring tools, such as ordinary rulers or tape measures, have many limitations when measuring trauma. They are ill-suited to irregular wound shapes and cannot accurately measure the wound area.

[0003] Therefore, this utility model proposes a wound measuring ruler for accurate wound measurement. Utility Model Content

[0007] The auxiliary ruler has a cuboid structure and a channel inside it. The auxiliary ruler is fitted onto the horizontal plate through the channel. The top of the auxiliary ruler has a threaded through hole and a fixing bolt.

[0008] The auxiliary ruler has a winding mechanism inside; the winding mechanism is located below the channel, and the winding mechanism includes a mandrel, a rotating disk, a winding spring, and a mesh film. The mandrel is installed inside the auxiliary ruler, the rotating disk is rotatably mounted on the mandrel, the winding spring is installed at the center of the rotating disk, one end of the mesh film is fixed to the outside of the rotating disk, the mesh film is wound on the rotating disk, and the other end of the mesh film is fixed to the vertical plate.

[0009] Preferably, the secondary ruler has an opening on the side near the vertical plate, the width of which matches the width of the mesh film, and the mesh film extends smoothly from the opening and is fixed to the inside of the vertical plate.

[0010] Preferably, when the fixing bolt is tightened, the bottom of the bolt is in close contact with the top of the main scale plate, thereby limiting the position of the auxiliary scale on the plate.

[0011] Preferably, the main scale is made of a transparent material.

[0012] Preferably, the minimum division value of the scale line is 1 millimeter.

[0013] Preferably, one end of the winding spring is fixedly connected to the spindle, and the other end is fixedly connected to the inner wall of the turntable.

[0014] The beneficial effects of this utility model are as follows:

[0015] High measurement accuracy: The main scale and mesh membrane can accurately measure the length, width and area of ​​the wound, providing doctors with detailed and accurate trauma data, which helps to develop more scientific and reasonable treatment plans.

[0016] Easy to operate: The auxiliary ruler can slide along the horizontal plate of the main ruler and can be quickly fixed in position by fixing bolts, facilitating measurement in different locations. The automatic winding function of the mesh film greatly improves the ease of operation.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] As shown in the attached diagram, a wound measuring ruler includes a main scale 100 and a secondary scale 200. The main scale 100 has an L-shaped structure, consisting of a horizontal plate 101 and a vertical plate 102 that are perpendicular to each other. Both the horizontal plate 101 and the vertical plate 102 have graduation lines, with the smallest graduation value being 1 millimeter. The secondary scale 200 has a cuboid structure with an internal channel 201. The secondary scale 200 is fitted onto the horizontal plate 101 of the main scale 100 through this channel 201 and can slide freely along the horizontal plate 101. The top of the secondary scale 200 has a threaded through hole, through which a fixing bolt 202 is installed. When the fixing bolt 202 is tightened, the bottom of the bolt 202 is in close contact with the top of the horizontal plate 101 of the main scale 100, thereby precisely limiting the position of the secondary scale 200 on the horizontal plate 101.

[0025] The auxiliary scale 200 has an internal winding mechanism located below the channel 201. The winding mechanism includes a spindle 203, a rotating disk, a winding spring 204, and a mesh membrane 205. The spindle 203 is securely mounted inside the auxiliary scale 200, and the rotating disk is rotatably mounted on the spindle 203. The winding spring 204 is installed at the center of the rotating disk, with one end fixedly connected to the spindle 203 and the other end fixedly connected to the inner wall of the rotating disk. One end of the mesh membrane 205 is fixed to the outside of the rotating disk and then wound around it; the other end of the mesh membrane 205 is fixed to the vertical plate 102 of the main scale 100. The auxiliary scale 200 has an opening on the side near the vertical plate 102, the width of which matches the width of the mesh membrane 205. The mesh membrane 205 extends smoothly from the opening and is fixed to the inside of the vertical plate 102. The mesh membrane 205 has a 2*2mm grid, enabling accurate measurement of the wound area.

[0026] The main scale 100 is made of transparent material, allowing doctors to clearly observe the actual condition of the wound when measuring it, avoiding measurement errors caused by obstruction and improving the accuracy and reliability of the measurement.

[0027] When measuring the length and width of a wound, measurements can be taken directly using the horizontal or vertical blades of the main ruler. To measure the wound area, the secondary ruler is pulled outwards, extending the mesh membrane 205 to cover the wound surface. Since the mesh membrane 205 has a 2*2mm grid, the area of ​​the wound can be accurately determined by calculating the number of grids covering it. After measurement, the mesh membrane 205 automatically retracts into the secondary ruler 200 under the action of the rewind spring 204 for convenient future use.

[0028] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
