When the patient measures the length and thickness of the limbs, the patient needs to use the measuring ruler and the measuring tape respectively to evaluate the lower limb force line and the knee varus and valgus, and the long ruler, the measuring tape and the angle measurer need to be combined.

The patient does not purchase various measuring tools for the patient, and there is a risk of cross-infection when selecting a common measuring tool. Even if the patient purchases various measuring tools, it is very inconvenient to store and carry the measuring tools because the number of the measuring tools is large.

Detailed Description

A portable multifunction ruler capable of measuring various parameters as shown in fig. 1 to 2 includes an angle scale 1, a thigh length ruler 2, a shank length ruler 3, a thigh tape measure 4, and a shank tape measure 5. In one aspect, the thigh length scale is 15cm in length, the calf length scale is 15cm in length, the thigh tape measure is 60cm in length, and the calf tape measure is 50cm in length. The thigh measuring tape 4 is connected to the thigh length ruler 2, and the shank measuring tape 5 is connected to the shank length ruler 3. The angle dial 1 is used for measuring the moving angle of the knee joint, namely the extension and flexion angle of the knee joint. The thigh length scale 2 measures the thigh length directly, or in combination with the thigh tape measure 4, the thigh length, i.e. from the lateral centre point of the knee joint to the anterior superior iliac spine. The calf length ruler 3 is used for directly measuring the calf length, or the calf length ruler is combined with a calf measuring tape 5 and used for measuring the calf length, namely the calf length from the lateral center point of the knee joint to the lateral malleolus. The long ruler is straightened from the midpoint of the groin and the midpoint of the medial and lateral malleoli, then the midpoint of the angle dial faces the midpoint of the patella, and the angle formed by the angle dial is the varus-valgus angle of the knee joint, so that the force line condition of the knee joint is judged, and the valgus-valgus angle of the knee joint is measured. The thigh tape measure 4 is used for measuring the thickness of the thigh, and the shank tape measure 5 is used for measuring the thickness of the shank.

One end of the shank length ruler 3 is connected with the center of the angle dial 1 through the rotating shaft 11, so that the shank length ruler 3 can rotate around the center of the angle dial 1. One end of the thigh length ruler 2 is fixedly connected with the angle dial 1 or is rotationally connected with the dial 1 through a rotating shaft 11.

As shown in fig. 1, a thigh tape measure 4 and a shank tape measure 5 are fixedly mounted on the thigh length scale 2 and the shank length scale 3, respectively. In other embodiments, the thigh tape measure and the calf tape measure are movable on the thigh length scale and the calf length scale, respectively, and the measuring positions of the thigh tape measure and the calf tape measure are adjusted according to the limb lengths of the actual patients, such as different heights, or the measuring positions are affected by surgical wounds.

For example, as shown in fig. 3, rough

surface fastening tapes

211 and 311 are attached to the thigh length scale 2 and the shank length scale 3 in a range of 10cm to 15cm, and hook

surface fastening tapes

411 and 511 are attached to the ends of the thigh tape measure 4 and the shank tape measure 5, respectively. The positions of the thigh measuring tape or the shank measuring tape on the thigh length ruler or the shank length ruler are adjusted by sticking the hook surface fastening tape on different positions of the hair surface fastening tape.

slot

212 and 312 in the 10cm to 15cm section of the side surface, the slot is opened to the end of the length ruler, the

movable buckle

412 and 512 are respectively arranged at the ruler end of the thigh measuring tape 4 and the shank measuring tape 5, the ruler end of the thigh measuring tape 4 and the shank measuring tape 5 can move to the end of the length ruler to be extended to be an extension ruler of the length ruler, and the buckle can slide in the slot and can not be separated from the slot when the length ruler is supplemented. In a more specific aspect, as shown in fig. 5, the movable catch includes a slide bar and a cap. The diameters of the sliding rod 4121 and the sliding rod 5121 are smaller than the opening of the clamping groove, and the sliding rod respectively penetrates through the lower end of the thigh measuring tape or the shank measuring tape and then is inserted into the clamping groove of the corresponding length measuring tape and can move in the clamping groove. The diameter of the cap 4122 and the cap 5122 is larger than the opening of the clamping groove, and after the sliding rod is inserted into the clamping groove, the caps are buckled at the two ends of the sliding rod to prevent the sliding rod from falling from the clamping groove.

The angle scale 1, thigh length scale 2 and shank length scale 3 are made of rigid material, such as hard plastic or steel sheet. The angle dial can be semicircular or circular, and scales are arranged on the angle dial. In a specific embodiment, the thigh length scale 2 is provided with a scale, for example, the total length of the thigh length scale is 15cm, and the scale mark on the thigh length scale is a 15cm bisector. The shank length ruler 3 is provided with scales, for example, the total length of the shank length ruler is 15cm, and the scale marks on the shank length ruler are 15cm bisectors. The starting point of the scales (i.e., 0 scale) of the thigh length scale and the shank length scale is the center point (the position of the rotating shaft 11) of the angle scale. Specifically, taking the connection of the thigh length scale and the shank length scale with the rotating shaft of the angle dial as an example, the center of the rotating shaft is set to be 0 scale of the length scale. The thigh measuring tape and the shank measuring tape are made of flexible or rollable materials so as to measure the thickness of the thigh or the shank. The thigh measuring tape is provided with a scale mark, for example, a scale mark with the total length of 60cm, and the shank measuring tape is provided with a scale mark, for example, a scale mark with the total length of 50 cm.

The portable multifunctional ruler capable of measuring various parameters in fig. 6 is further optimized on the basis of the multifunctional ruler in fig. 1, and comprises an angle dial 1, a thigh length ruler 2 and a shank length ruler 3, wherein a thigh measuring tape 4 is arranged on the thigh length ruler, and a shank measuring tape 5 is arranged on the shank length ruler. As shown in fig. 6 and 7, the thigh length ruler and the shank length ruler respectively comprise a ruler storage groove 6, the ruler storage groove is provided with a cross rod 61, a reel 63 is sleeved on the cross rod, and a thigh measuring tape and a shank measuring tape are respectively connected on the reel. The reel can slide on the cross rod, so that the tape measure is driven to move, and the tape measure reaches a position to be measured. As shown in fig. 8 and 9, the tape measure may be wound onto the spool as the spool rotates on the crossbar so as to be received in the tape storage slot. As shown in fig. 10 and 11, an opening 64 is formed in the side wall of the tape storage groove, and the tape measure can extend out of the opening, so that the tape measure can be more attached to the thigh or the calf during measurement, and the measurement is more accurate.
