Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pressure gauge capable of measuring pressure and lower limb circumference at the same time. Background Art

[0002] Varicose veins of the lower extremities are common and frequently occurring diseases in vascular surgery. The prevalence rates in men and women over 18 years old in my country are as high as 10% to 15% and 20% to 25% respectively, and the patient population base is huge. Mild varicose veins of the lower extremities may manifest as heaviness, fatigue and swelling of the lower extremities, edema, and tortuous dilatation of the superficial veins of the lower extremities; while the progression of the disease may lead to pigmentation of the skin of the lower extremities, itching of the skin, and even prolonged ulceration, which seriously affects the patient's quality of life and brings both psychological and economic pressure to the patient. Varicose veins with a long course of disease may also lead to life-threatening diseases such as deep vein thrombosis of the lower extremities and even pulmonary thromboembolism.

[0003] There are many treatments for varicose veins in the lower extremities, including pressure therapy, drug therapy, sclerotherapy, and surgery. Among them, pressure therapy is the basic means of treating varicose veins in the lower extremities. Whether it is conservative treatment or pre- and post-operative treatment of surgical treatment, pressure therapy is always used throughout. Pressure therapy is non-invasive and does not require medication. It is easy to use, so patients have better compliance.

[0004] Pressure therapy includes elastic stockings, elastic bandages, and pneumatic compression therapy, among which elastic stockings are the most common treatment method. Elastic stockings, also called graduated decompression elastic stockings, promote venous return by applying gradient pressure to the limbs, thereby improving the state of blood stasis in the lower limbs, relieving symptoms such as swelling, heaviness, fatigue, and pain in the lower limbs, slowing the progression of varicose veins, and promoting the healing of venous ulcers in the lower limbs. At present, the use of elastic stockings to treat varicose veins in the lower limbs has become a recognized treatment method worldwide, and has also achieved relatively significant results in clinical practice. The 2022 European Association for Vascular Surgery Clinical Practice Guidelines for the Management of Chronic Venous Disease of the Lower Limb recommend: ① For patients with symptomatic chronic venous disease, it is recommended to use elastic stockings to apply at least 15 mmHg of pressure at the ankles to relieve venous symptoms; ② For patients with chronic venous disease and edema, it is recommended to use below-the-knee elastic stockings to apply 20-40 mmHg of pressure at the ankles to reduce edema; ③ For patients with chronic venous disease and liposclerosis and / or white atrophy, it is recommended to use below-the-knee elastic stockings to apply 20-40 mmHg of pressure at the ankles to reduce skin nodules.

[0005] It is very important to match the specifications of the elastic stockings with the patient's symptoms. It is necessary to ensure that the pressure exerted by the elastic stockings on specific parts of the patient's lower limbs meets the treatment standards. Too little pressure will lead to poor treatment effects and worsen the disease; too much pressure will affect the patient's comfort and reduce patient compliance; at the same time, too much pressure may also hinder the blood supply to the patient's lower limb arteries and cause arterial diseases.

[0006] At present, one model of elastic stockings on the market corresponds to a set of size ranges. In actual operation, medical staff use conventional tape measures to measure the circumference of the ankles, the thickest part of the calf and the middle part of the thigh of the patient's lower limbs, and then select elastic stockings that meet the patient's size based on the measurement results and the size range given by the elastic stockings merchants on the market.

[0007] Since a certain size of elastic stockings corresponds to a certain range of sizes, and the thickness of each patient's lower limbs varies within this range, and due to differences in individual physiological characteristics, elastic stockings of the same size may also produce different pressures on different patients, it is not guaranteed that every patient can choose elastic stockings that are completely suitable for them. Especially for patients with complex symptoms, personalized elastic stockings may be needed.

[0008] However, existing tape measures can only measure the circumference of the lower limbs and cannot reflect the pressure, so personalized customization of elastic stockings is not possible. Utility Model Content

[0009] The embodiment of the present application provides a pressure gauge to solve the technical problems in the prior art that the tape measure can only measure the circumference of the lower limbs but cannot reflect the pressure and does not support the personalized customization of elastic stockings. The pressure gauge takes into account the pressure and diameter measurement requirements, and can measure the corresponding circumference of the lower limbs when the treatment pressure target is reached, laying a foundation for the personalized customization of elastic stockings.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] In order to better understand the above technical solution, exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices consistent with some aspects of the present application as detailed in the attached claims.

[0040] Figure 1 and Figure 2 This is a schematic diagram of the structure of a pressure gauge provided in an embodiment of the present application, wherein the pressure gauge comprises:

[0041] A housing 1, wherein a rotating shaft is provided in the housing 1;

[0042] A measuring tape 2 is wound around the rotating shaft, and a free end of the measuring tape 2 extends out of the housing 1;

[0043] An adjusting knob 3 is disposed outside the housing 1 and connected to the rotating shaft, and is used to drive the rotating shaft to rotate in a forward or reverse direction, so as to adjust the measuring tape 2 to be wound onto the rotating shaft or released from the rotating shaft;

[0044] The pressure sensor 4 is embedded inside the free end of the measuring tape 2 .

[0045] In a preferred embodiment, the front end of the housing 1 is provided with an arc-shaped fitting surface 11 for fitting with the lower limbs of the patient to be measured. One side of the arc-shaped fitting surface 11 is provided with a ruler outlet 12, and the free end of the measuring tape 2 passes through the ruler outlet 12 to the outside of the housing 1.

[0046] In a preferred embodiment, a slot 13 is provided on the other side of the arc-shaped fitting surface 11, and a clamping column 21 is provided at the free end of the measuring tape 2. The clamping column 21 is configured to be clamped in the slot 13 to enclose a lower limb accommodating space between the measuring tape 2 and the arc-shaped fitting surface 11.

[0047] Furthermore, the thickness of the outlet 12 is greater than the thickness of the tape measure 2 and smaller than the outer diameter of the clamping column 21, so that the tape measure 2 can freely pass through the outlet 12, but the clamping column 21 is clamped outside the housing 1. This ensures that when the adjustment knob 3 drives the shaft to rotate in the forward direction to adjust the tape measure 2 to be wound around the shaft, the clamping column 21 will not be rolled into the housing 1 even when it is turned to the end.

[0048] Combination Figure 3Further, the clamping slot 13 includes a clamping column positioning slot 131 and a tape measure side slot 132. The structure of the clamping column positioning slot 131 matches the structure of the clamping column 21, and is used to position the clamping column 21. The structure of the tape measure side slot 132 matches the body of the tape measure 2, and is used to accommodate the free end of the body connected to the clamping column 21. One end of the tape measure side slot 132 is connected to the clamping column positioning slot 131, and the other end extends to the other side of the arc-shaped fitting surface 11.

[0049] The slot 13 is connected to at least one side of the housing 2, so that the clamping column 21 can be inserted into the slot 13 from the side of the housing 2. After insertion, the clamping column 21 is placed in the clamping column positioning groove 131, and the free end of the tape body connected to the clamping column 21 is placed in the tape measure side cut groove 132. At this time, a circle of lower limb accommodation space is enclosed between the tape measure 2 and the arc-shaped fitting surface 11, and the circumference of the lower limb can be measured.

[0050] Furthermore, the surface of the tape measure 2 is provided with a scale to facilitate reading the circumference measurement result of the lower limb. After the clamping column 21 is inserted into the clamping column positioning groove 131, the position where the tape measure body is connected to the other side of the arc-shaped fitting surface 11 ( Figure 2 That is, the portion of the tape body placed in the side cut groove 132 of the tape measure is blank and no size is marked.

[0051] In a preferred embodiment, the length of the arcuate fitting surface 11 is M, and the starting value of the scale is the length M of the arcuate fitting surface 11. Since the arcuate fitting surface 11 fits the lower limb during measurement and also constitutes a part of the circumference, the length of the arcuate fitting surface needs to be considered when calculating the circumference of the lower limb. For the sake of simplicity of calculation, the starting value of the scale is set to the length of the arcuate fitting surface 11, and when reading, the reading of the tape measure 2 at the outlet 12 can be directly read.

[0052] In an optional embodiment, the measuring tape 2 is set to have a measuring length of 1 meter.

[0053] In a preferred embodiment, the pressure sensor 4 is a flexible pressure sensor. The flexible pressure sensor is embedded inside the measuring tape 2 and is flexible like the measuring tape 2. During measurement, the flexible pressure sensor fits the patient's lower limbs flexibly without affecting the comfort of measurement.

[0054] The flexible pressure sensor has excellent mechanical and electrical properties, and has the advantages of high flexibility, high sensitivity, high resolution and fast response, etc. The flexible pressure sensor can be a flexible pressure sensor made of graphene, carbon nanotubes, metal nanowires or other highly sensitive materials.

[0055] In a preferred embodiment, the pressure gauge further comprises a display screen 5, which is disposed on the housing 2 and connected to the pressure sensor 4. The display screen 5 is used to display data measured by the pressure sensor 4.

[0056] Combination Figure 4 Furthermore, the pressure gauge also includes a control unit, which is connected to the pressure sensor 4 and the display screen 5; the control unit is provided with a target pressure setting module, and when in use, the target pressure value for each measurement can be set according to the actual situation of the patient.

[0057] In a preferred embodiment, the pressure gauge further includes an alarm device, which is connected to the control unit and is used to send out a warning signal when the data measured by the pressure sensor reaches the target pressure, to remind the user to complete the measurement and record the measurement data.

[0058] When the pressure gauge provided in the embodiment of the present application is used, the specific method is as follows:

[0059] Fit the arc-shaped fitting surface 11 to the target limb, wrap the measuring tape 2 around the target limb and insert the clamping column 21 into the clamping slot 13 on the housing 1 from the side;

[0060] The adjustment knob 3 is turned to adjust the tightness of the tape measure 2, and the pressure sensor 4 measures in real time the pressure exerted by the tape measure 2 on the target limb at the current tightness; at the same time, the display screen 5 displays the measured value of the pressure sensor 4 in real time;

[0061] Observe the pressure reading on the display screen 5, and when the target pressure is reached, read the circumference value of the current target limb and record the data.

[0062] In a preferred embodiment, before measurement, a target pressure value for this measurement is set by a target pressure setting module of the control unit.

[0063] During the measurement process, the adjustment knob 3 is turned to adjust the tightness of the tape measure 2. When the pressure exerted by the tape measure 2 on the target limb (i.e., the measurement value of the pressure sensor 4) reaches the target pressure, the alarm device sends a warning signal to remind the user to complete the measurement. The current circumference value of the target limb is read and the data is recorded.

[0064] Subsequently, the measured circumference and target pressure data can be transmitted to the production factory to customize elastic stockings that meet the patient's individual requirements.

[0065] Generally, the pressure gauge can be used to impart appropriate size and pressure to key parts of the lower limbs that are easily subjected to pressure, such as the knee joints, the middle of the calf, the ankle joints and other special parts, to achieve a gradual pressure effect.

[0066] The pressure gauge provided in the embodiment of the present application takes into account the pressure and diameter measurement requirements, and can measure the corresponding lower limb circumference when the treatment pressure target is reached, laying a foundation for the personalized customization of elastic stockings. It can be used to individually configure elastic stockings that can meet the treatment standards for patients with varicose veins of the lower limbs, thereby achieving satisfactory treatment effects, improving patient symptoms, and delaying disease progression.

[0067] The pressure gauge provided in the embodiment of the present application has a simple structure, low cost, easy operation, high intelligence, and is suitable for large-scale promotion and use.
