A leg circumference measuring ruler for VTE patients

Abstract

This utility model relates to the field of leg circumference measurement technology for VTE patients, and more particularly to a leg circumference measuring ruler for VTE patients. The technical problem is that existing leg circumference measuring rulers are difficult to fix the patient's patella before measurement, leading to measurement point misalignment during subsequent measurements. Furthermore, each patient's situation is different, and existing leg circumference measuring rulers are not easily adjusted according to the patient's condition; the measuring tape is difficult to be perpendicular to the long axis of the limb, resulting in inaccurate measurement results. A leg circumference measuring ruler for VTE patients includes: a mounting plate with a groove; three pads fixed to the bottom of the mounting plate; and two leg supports at both ends of the mounting plate. Depending on the patient's leg circumference, one side of the outer casing contacts the patient's leg. Then, the operator rotates the retractor in the opposite direction to tighten the measuring ruler and wrap it around the patient's leg. Adjustments are then made according to the patient's leg to ensure the measuring tape is perpendicular to the long axis of the limb and the tightness is appropriate, thus making the measurement more accurate.

Description

Technical Field

[0001] This utility model relates to the field of leg circumference measurement technology for VTE patients, and in particular to a leg circumference measuring ruler for VTE patients. Background Technology

[0002] Deep vein thrombosis (VTE) of the lower extremities is a common and potentially fatal disease in clinical practice. Leg circumference measurement is an important indicator for screening and monitoring DVT. When measuring the leg circumference of VTE patients, staff usually use a measuring tape to measure the leg circumference value.

[0003] Because patients' positions are prone to change during measurement, and existing leg circumference measuring rulers are difficult to fix the patient's patella before measurement, the measurement point is easily offset during subsequent measurements. Furthermore, each patient's situation is different, and existing leg circumference measuring rulers are not easy to adjust according to the patient's situation. The measuring tape is also difficult to be perpendicular to the long axis of the limb, resulting in inaccurate measurement results. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, this utility model provides a leg circumference measuring ruler for VTE patients. It can fix the patient's patella to prevent the measurement point from shifting during subsequent measurements, and can be adjusted according to the patient's condition to make the measuring tape perpendicular to the long axis of the limb, thereby improving the accuracy of the measurement.

[0005] Technical solution: A leg circumference measuring ruler for VTE patients, comprising:

[0006] A mounting plate with a groove;

[0007] Three pads are fixed to the bottom of the mounting plate;

[0008] Two leg supports are located at both ends of the mounting plate;

[0009] A positioning plate fixed to one end of the mounting plate;

[0010] Fixed components, mounted on the mounting plate;

[0011] The measuring components are mounted on the mounting plate.

[0012] Furthermore, it is particularly preferred that the mounting plate is provided with graduations.

[0013] Furthermore, it is particularly preferred that the fixation component includes: a patellar brace slidably connected to a groove on the mounting plate; a strap disposed on the patellar brace, one end of the strap passing through one end of the patellar brace; and a knob threadedly connected to the patellar brace.

[0014] Furthermore, it is particularly preferred that the measuring assembly includes: two sliding plates slidably connected to the mounting plate, the two sliding plates being located on both sides of the patellar support; a lead screw rotatably connected to each of the two sliding plates, and a movable plate threadedly connected to each of the two lead screws; a housing fixedly connected to each of the two movable plates, and a slot provided on each of the two housings; a winding post rotatably connected to each of the two housings; a measuring scale wound around each of the two winding posts; and a locking rod provided at one end of each of the two measuring scales.

[0015] Furthermore, it is particularly preferred that the measuring ruler is made of inelastic fiber material.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The patient lies flat with both legs straight and rests on the leg support. The positioning plate is placed against the patient's feet. Then, the staff adjusts the patella support to the patella position and fixes the patella with straps and knobs to prevent the legs from shifting during subsequent measurements. This ensures that the measurement plane is perpendicular to the long axis of the limb, eliminates positional errors, and ensures the accuracy of subsequent measurements.

[0017] 2. Based on the patient's leg thickness, place one side of the outer casing against the patient's leg. Then, the operator rotates the rewind column in the opposite direction. The reverse rotation of the rewind column will tighten the measuring tape and wrap it around the patient's leg. Adjustments are then made according to the patient's leg to ensure that the measuring tape is perpendicular to the long axis of the limb and the tension is appropriate, thus making the measurement more accurate. The operator records the values ​​on the measuring tape. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] Example 1: A leg circumference measuring ruler for VTE patients, such as Figures 1-5 As shown, it includes:

[0026] Mounting plate 1 with a groove;

[0027] Three pads 2 are fixed to the bottom of the mounting plate 1;

[0028] Two leg supports 3 are provided at both ends of the mounting plate 1;

[0029] Positioning plate 4 is fixed to one end of mounting plate 1;

[0030] A fixation component for fixing the patient's patella is mounted on mounting plate 1;

[0031] A measuring component for measuring leg circumference is mounted on mounting plate 1.

[0032] The mounting plate 1 is provided with a scale, which is used to facilitate the adjustment of the measurement position.

[0033] The fixation assembly includes: a patellar support 5 that is slidably connected to a groove in the mounting plate 1; a strap 6 provided on the patellar support 5, one end of which passes through one end of the patellar support 5; and a knob 7 that is threadedly connected to the patellar support 5.

[0034] The measuring assembly includes: two sliding plates 8 slidably connected to the mounting plate 1, the two sliding plates 8 being located on both sides of the patellar support 5; each of the two sliding plates 8 is rotatably connected to a lead screw 10, and each of the two lead screws 10 is threadedly connected to a movable plate 9; each of the two movable plates 9 is fixedly connected to a housing 11, and each of the two housings 11 is provided with a slot; each of the two housings 11 is rotatably connected to a winding post 12; each of the two winding posts 12 is wound with a measuring ruler 13; and each of the two measuring rulers 13 is provided with a locking rod 14 at one end.

[0035] The measuring ruler 13 is made of inelastic fiber material, which is used to prevent deformation during measurement.

[0036] When measuring the leg circumference of a VTE patient, the mounting plate 1 is first placed flat on the hospital bed. The patient then lies flat with both legs straight and resting on the leg support 3. The positioning plate 4 is placed against the patient's feet. The staff then adjusts the patellar support 5 to the patella position and secures the patella using the strap 6 and knob 7 to prevent leg displacement during subsequent measurements. This ensures that the measuring plane is perpendicular to the long axis of the limb, eliminating positional errors and ensuring accuracy. The staff then pulls out the measuring ruler 13 and passes it under the patient's leg, while simultaneously locking the locking rod 14 into the slot on the outer casing 11. The staff then moves the sliding plate 8 according to the scale on the mounting plate 1, positioning the two measuring rulers 13 at the upper and lower edges of the patient's patella, respectively. At a certain position, the operator rotates the lead screw 10, causing the moving plate 9 to move under the action of the thread. Depending on the thickness of the patient's leg, one side of the outer casing 11 contacts the patient's leg. Then, the operator rotates the rewind column 12 in the opposite direction. The reversal of the rewind column 12 will tighten the measuring ruler 13 and wrap it around the patient's leg. The operator then makes corresponding adjustments according to the patient's leg to make the measuring ruler perpendicular to the long axis of the limb and with appropriate tightness, so that the measurement is more accurate. The operator records the value on the measuring ruler 13. After a short interval, this operation is repeated. After measuring the values ​​of the thigh and calf several times, the average value of the data is taken. After the measurement is completed, the operator pulls out the locking lever 14, rotates the rewind column 12 to retract the measuring ruler 13, loosens the strap 6, and the patient can move their leg away.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
