Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a limb circumference measuring ruler. Background Technique

[0002] In clinical practice, measuring the limb circumferences of high-risk venous thromboembolism (VTE) patients is an important step in evaluating limb swelling and thrombosis. The existing measurement methods generally involve medical staff using a tape measure by hand. The measurement includes multiple steps. For example, the measurement of the lower limb includes the following steps:

[0003] Step 1: Mark the upper and lower edges of the patella and measure the midpoint of the patella.

[0004] Step 2: Mark 15 cm above the midpoint of the patella and 10 cm below the midpoint of the patella.

[0005] Step 3: Place the upper edge of the tape measure at 15 cm above the midpoint of the patella, measure the limb circumference and mark the lower edge of the tape measure.

[0006] Step 4: Place the lower edge of the tape measure at 10 cm below the midpoint of the patella, measure the limb circumference and mark the upper edge of the tape measure.

[0007] Therefore, during the operation of medical staff holding the tape measure by hand, there are many operation steps, which further lead to larger errors caused by manual operation and inconvenient work. Moreover, the measurement points of the upper and lower limbs are different, which further increases the complexity of the measurement.

[0008] For this reason, we propose a limb circumference measuring ruler. Content of the Utility Model

[0009] The purpose of the utility model is to provide a limb circumference measuring ruler to solve the problems raised in the above background technique.

[0010] To achieve the above purpose, the utility model provides the following technical solution: A limb circumference measuring ruler includes a positioning ruler. The surface of the positioning ruler is provided with positioning holes. The surface of the positioning holes is provided with a positioning center line. The surface of the positioning ruler is provided with positioning scales. The positioning scales and the positioning ruler are distributed in parallel. The positioning scales are set in two sections and face both sides of the positioning ruler respectively. The zero scale position of the positioning scales is flush with the positioning center line. The surface of the positioning ruler is fixedly connected with measuring flexible rulers. The measuring flexible rulers are set in three groups. Two groups of the measuring flexible rulers are respectively set at the 10 cm scales on both sides of the positioning scales, and the other group of the measuring flexible rulers is set at the 15 cm scale above the positioning scales. The surface of the measuring flexible rulers is provided with measuring scales.

[0011] Preferably, the positioning holes are semi-circular.

[0012] Preferably, three groups of insertion holes are arranged on the surface of the positioning ruler. The three groups of insertion holes are sequentially distributed on one side of several groups of measuring flexible rulers, and the zero scale of the measuring scale is tangent to the positioning hole.

[0013] Preferably, one end of the measuring flexible ruler away from the positioning ruler is triangular, and the width of the measuring flexible ruler is smaller than the width of the insertion hole.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: This solution is formulated according to the "Expert Consensus on the Nursing Specification for Interventional Treatment of Lower Extremity Deep Venous Thrombosis", which can more simply, quickly and standardly measure the limb circumferences of clinical VTE high-risk patients, so as to achieve homogeneous and standardized measurement of the limb circumferences of patients, and also reduce the workload of clinical medical staff.

[0017] Embodiment

[0018] Please refer to Figure 1 , the present utility model provides a technical solution:

[0019] A limb circumference measuring ruler, a positioning hole 2 is arranged on the surface of the positioning ruler 1. The positioning hole 2 is set to be semi-circular, and the straight line of the positioning hole 2 is set as the positioning center line 3. When in use, the positioning ruler 1 is placed parallel to the patient's limb, the patient's limb joint is aligned through the positioning ruler 1, and further the joint center line of the patient is aligned through the positioning center line 3, so as to realize the positioning of the measurement of the patient's limb circumference by this device.

[0020] A positioning scale 4 is arranged on the surface of the positioning ruler 1. The positioning scale 4 and the positioning ruler 1 are arranged in parallel. The positioning scale 4 is set in two sections, respectively facing both sides of the positioning ruler 1, and the zero scale position of the positioning scale 4 is flush with the positioning center line 3. After further positioning the joint of the patient through the positioning center line 3, the measurement position of the patient's limb can be quickly located through the positioning scale 4.

[0021] The surface of the positioning ruler 1 is fixedly connected with three measuring flexible rulers 5. Two of the measuring flexible rulers 5 are respectively arranged on the 10-cm scale rulers on both sides of the positioning scale 4, and the other measuring flexible ruler 5 is arranged at the 15-cm scale on the upper side of the positioning scale 4. Further, through the position settings of the three measuring flexible rulers 5, when the device is in use, it can measure both the upper limb circumference and the lower limb circumference of the patient, thereby increasing the functionality and practicality of the device.

[0022] And the surface of the measuring flexible ruler 5 is provided with measuring scales 6. When the measuring flexible ruler 5 completes the positioning of the patient's limb measurement position, the measuring flexible ruler 5 is wound around the patient's limb for one week, and through the reading of the measuring scale 6, the circumference measurement of the patient's limb can be completed.

[0023] The surface of the positioning ruler 1 is provided with three sets of insertion holes 7, and the three sets of insertion holes 7 are sequentially distributed on one side of several sets of measuring flexible rulers 5. The zero scale of the measuring scale 6 is tangent to the positioning hole 2. When the measuring flexible ruler 5 is measuring, the measuring flexible ruler 5 is wound around the patient's limb for one week and passes through the insertion hole 7. Further, through the reading of the position where the measuring scale 6 passes through the insertion hole 7, the limb circumference of the patient can be accurately measured.

[0024] One end of the measuring flexible ruler 5 away from the positioning ruler 1 is triangular, and the width of the measuring flexible ruler 5 is smaller than the width of the insertion hole 7, which further enables the measuring flexible ruler 5 to be more conveniently inserted into the insertion hole 7 during use.

[0025] Specifically, when the device measures the upper limb circumference of the patient, it includes the following steps:

[0026] Step 1: Align the positioning hole 2 on the positioning ruler 1 with the upper limb joint of the patient, and align the positioning center line 3 with the elbow horizontal line of the patient to fix the positioning ruler 1.

[0027] Step 2: Use the measuring flexible ruler 5 at the upper 10 cm to wind around the elbow for one week, pass through the insertion hole 7 and record the value of the measuring scale 6, which is the circumference value at 10 cm above the elbow transverse line; in the same way, use the measuring flexible ruler 5 at the lower 10 cm to wind around the elbow for one week, pass through the insertion hole 7 and record the value of the measuring scale 6, which is the circumference value at 10 cm below the elbow transverse line.

[0028] When measuring the lower limb circumference of the patient, it includes the following steps:

[0029] Step 1: Align the positioning hole 2 on the positioning ruler 1 with the lower limb patella of the patient, and align the positioning center line 3 with the patella center line of the patient to fix the positioning ruler 1.
