Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pneumatic bandage. Background Art

[0002] Normally, healthy leg muscles squeeze the deep veins in the legs and feet to help blood return to the heart. One-way valves exist in the deep veins of the legs, which allow blood to flow back to the heart in one direction. However, standing or sitting for long periods of time can cause the walls of the deep veins in the legs to stretch. Over time, in susceptible people, this can weaken the vein walls and damage the valves, causing blood to pool in the veins and increase venous blood pressure, which can lead to chronic venous insufficiency (CVI). Signs and symptoms of chronic venous insufficiency include increased leg pain after standing for long periods of time, fatigue, heaviness, and varicose veins. More severe cases can manifest as progressive skin changes, venous stasis dermatitis, lipodermatosclerosis, and symptomatic ulcers. In general, conservative treatment can be performed with graded compression. In severe cases, open surgery or intravenous intervention is required, and medical elastic stockings or bandages should be worn after surgery to aid recovery.

[0003] Conservative treatment often involves the use of compression stockings or medical stockings to reduce chronic swelling. Compression stockings are elastic stockings that compress the veins to improve venous circulation and prevent excess blood from flowing backward. Compression stockings can also help heal skin ulcers or ecchymotic ulcers that accompany CVI. Using a compression bandage to apply pressure to the leg is also common. The bandage is applied with constant tension to create a gradient of compression with the highest pressure at the ankle.

[0004] While patients can wear stockings and / or bandages and apply them on their own, putting on compression stockings can be cumbersome or time-consuming, and may require assistance from others if the wearer is injured, elderly, or has some kind of disability. Furthermore, during use, the pressure applied by the stockings typically remains relatively constant, without any option to increase or decrease tightness. Excessive pressure can cause discomfort to the patient, and in severe cases, can even lead to local ischemia. Furthermore, because compression stockings are worn repeatedly, they lose their elasticity and tightness over time, impacting the progress and effectiveness of treatment. Therefore, there is a need for a compression therapy device that is easy to wear and provides stable, controllable pressure. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1 The utility model provides a pneumatic bandage, which has the following notable features: a bladder 4, a pressure sensor 3 and a display screen 5 are arranged in the bandage, the volume of the bladder 4 gradually decreases from bottom to top, and gas can be filled in or released in the bladder 4 to provide a gradual pressure to the affected part from the ankle to the knee, the pressure sensor 3 is arranged on the inner bandage 1, and the display screen 5 is arranged outside the bandage and electrically connected to the pressure sensor 3, the pressure sensor 3 detects the pressure applied to the affected part in real time, and the display screen 5 displays the current pressure detected by the pressure sensor 3 in real time. The patient can adjust the volume of gas filled in the bladder 4 in time according to the pressure value displayed on the display screen 5 and in combination with his or her own comfort, to ensure that the pressure applied to the affected part is always within the effective treatment range, while minimizing the discomfort caused by the pressure, which helps patients to insist on wearing the bandage correctly and effectively for a long time and ensure the treatment effect.

[0024] Specifically, please refer to Figure 2-3The pneumatic bandage comprises an inner bandage 1 and an outer bandage 2. To accommodate the physiological shape of the leg, both are roughly trapezoidal in shape, narrow at the bottom and wide at the top. The inner surface of the inner bandage 1 is provided with a recessed portion 11 that accommodates a pressure sensor 3. The shape of this recessed portion 11 matches the shape of the pressure sensor 3. Because the leg is treated with pressure-dividing therapy, the pressure gradually decreases from the ankle upwards. Therefore, for accurate monitoring, three pressure sensors 3 are arranged along the axial direction of the leg, specifically distributed at the ankle, mid-calf, and upper calf. The inner surface of the outer bandage 2 is provided with a conduit 24 that accommodates the bladder 4. The bladder 4 is a multi-section curved tube, with the diameter of the tube gradually increasing from the upper calf to the ankle. When the bladder 4 is filled with air, the ankle is subjected to the greatest pressure, thus achieving the effect of pressure-dividing therapy. An inflation port 41 is provided at the upper end of the bladder 4, through which various inflation devices can inject gas into the bladder 4. A deflation port 42 is provided at the lower end of the bladder 4 for reducing pressure. Overall, the bladder 4 is positioned between the inner bandage 1 and the outer bandage 2, with the inflation port 41 emerging from between the inner and outer bandages 1 and 2, and the deflation port 42 emerging from the bottom of the outer bandage 2.

[0025] Multiple straps 21 are set on both sides of the outer bandage 2, and the relative straps 21 on each side are staggered in the axial direction, and the two opposite straps 21 are respectively provided with hook-surface Velcro and fleece material. Therefore, the bandage can be fixed to the leg through the straps 21, and after fixation, the entire outer surface of the bandage is roughly flat. Compared with common bandages, it is more beautiful and generous, which increases the patient's willingness to wear it.

[0026] In addition, a display screen accommodating area 22 for accommodating the display screen 5 is provided on the outer surface of the outer bandage 2. The display screen 5 can be embedded in this area so that the display screen and the outer bandage 2 are on the same surface. Of course, the display screen 5 can also be fixed to the outer bandage 2 in a buckled manner without being embedded in the outer bandage 2.

[0027] In addition, ventilation holes 23 are provided on the outer bandage 2 to increase the ventilation and comfort of the patient's legs.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
