Description

Technical Field

[0001] The invention relates to the technical field of nursing equipment, and in particular to an anti-thrombotic pressure belt which can be easily and quickly inflated. Background Art

[0002] The anti-thrombotic pressure belt is an auxiliary device that can effectively prevent deep vein thrombosis in the lower limbs after surgery. Its principle is to promote blood return in the lower limbs and reduce the risk of thrombosis by gradually reducing the pressure from the ankle to the thigh root. It is widely used in clinical practice for patients who are bedridden for a long time or need to prevent thrombosis after surgery.

[0003] Most of the existing anti-thrombotic pressure belts are wearable, similar to socks worn on the lower limbs. The pressure is controlled by the knitting density of the special elastic material of the socks. The knitting density is high near the patient's ankles, and low near the patient's thighs. The knitting density is gradually reduced to control the step-by-step change of pressure. Due to the different thicknesses of the lower limbs of different patients, the required pressure is bound to be different, and the currently commonly used anti-thrombotic pressure belts only have a few common sizes, which cannot meet the needs of all patients. If the pressure of the anti-thrombotic pressure belt is too high, the blood reflux effect is poor; if the pressure is too low, the anti-thrombotic effect cannot be achieved.

[0004] Therefore, an anti-thrombotic pressure belt which can be easily and quickly inflated is proposed. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 , the present invention provides a technical solution:

[0030] An anti-thrombotic pressure belt that is convenient and quickly inflated, comprising a pressure belt body 1 worn on the thigh and calf of a patient, the pressure belt body 1 being adapted to the size of the patient's leg, wherein the diameter of the opening at the top of the pressure belt body 1 gradually decreases to the diameter of the opening at the bottom, a passive extrusion airbag 2 is fixed at the middle position of the pressure belt body 1 corresponding to the inner side of the patient's knee joint, and the passive extrusion airbag 2 is designed to be elliptical in shape and to match the inner side of the patient's knee joint;

[0031] The inner ring of the pressure belt body 1 is equidistantly distributed with leg massage belts 6 for leg massage, and the leg massage belts 6 are pneumatically transmitted with the passive squeezing airbags 2;

[0032] A pneumatically adjustable tightening structure is arranged inside the pressure belt body 1, and the pneumatically adjustable tightening structure includes a middle-layer pressure expansion bag 4 and an elliptical inflatable bag 17. By pressing the elliptical inflatable bag 17 to inflate the middle-layer pressure expansion bag 4, the internal space of the pressure belt body 1 is reduced, thereby achieving the tightening of the legs inside the pressure belt body 1.

[0033] Specifically, if Figure 2 As shown, the pressure belt body 1 includes a pressure belt outer layer 3 and a pressure belt inner layer 5, wherein the pressure belt outer layer 3 is sleeved on the outside of the pressure belt inner layer 5, wherein the pressure belt inner layer 5 and the pressure belt outer layer 3 are both made of elastic fabrics, wherein the elastic force of the pressure belt outer layer 3 is greater than that of the pressure belt inner layer 5.

[0034] By adopting the above technical solution, the elastic force of the outer layer 3 of the medium pressure belt is greater than that of the inner layer 5 of the pressure belt, so that when the user subsequently inflates the inner part of the pressure belt, the expansion and tightening force is distributed toward the center.

[0035] Specifically, if Figure 2 As shown, the middle layer pressure expansion bag 4 and the elliptical inflatable bag 17 are located between the pressure belt outer layer 3 and the pressure belt inner layer 5, and the middle layer pressure expansion bag 4 and the elliptical inflatable bag 17 are respectively adhered and fixed to the inner wall of the pressure belt outer layer 3 and the outer surface of the pressure belt inner layer 5.

[0036] By adopting the above technical solution, the middle-layer pressure expansion bag 4 is mainly inflated. After the middle-layer pressure expansion bag 4 is inflated, the inner side thereof expands and extends toward the center, thereby increasing the tightening force on the leg surface.

[0037] Specifically, if Figure 2 As shown, the middle-layer pressure expansion bag 4 is integrally connected to the elliptical airbag 17, and the middle-layer pressure expansion bag 4 is communicated with the elliptical airbag 17. The length of the elliptical airbag 17 is consistent with the pressure belt body 1, and the lateral top-view cross-section is an elliptical structure design.

[0038] By adopting the above technical solution, the elliptical airbag 17 is mainly used to press and expand the middle-layer pressure expansion bag 4 to tighten the legs. By controlling the air supply of the elliptical airbag 17, the expansion force of the middle-layer pressure expansion bag 4 is controlled, and the tightening force on the leg surface is further adjusted.

[0039] Specifically, if Figure 2 and Figure 4 As shown, the middle layer pressure expansion bladder 4 includes an expansion bladder outer layer 7 and an expansion bladder inner layer 8 which are integrally connected and fixed, wherein the thickness of the expansion bladder outer layer 7 is greater than the thickness of the expansion bladder inner layer 8, a Velcro hook surface 18 is adhered and fixed to the upper side of the inner wall of the elliptical inflatable bladder 17, and a Velcro velvet surface 19 is adhered to the lower side of the inner wall of the elliptical inflatable bladder 17, an outer layer pull tab 14 and an inner layer pull tab 15 are vertically fixed to the corresponding positions of the outer wall, inner wall and elliptical inflatable bladder 17 of the pressure belt body 1, and a silicone elastic ring 16 is fixed to the middle of the elliptical inflatable bladder 17.

[0040] By adopting the above technical solution, the user presses the outer side of the belt body according to the wearing comfort and the required tightening pressure of the pressure belt body 1 on the leg, and presses the elliptical airbag 17. The user slowly pushes and presses along the two end edges of the elliptical airbag 17 toward the center of the elliptical airbag 17 with both hands. During the pushing and pressing process, the Velcro velvet surface 19 in the elliptical airbag 17 contacts and fixes with the Velcro hook surface 18. The elliptical airbag 17 is squeezed, and the internal gas is transported to the middle-layer pressure expansion bag 4. The middle-layer pressure expansion bag 4 expands. Since the thickness of the inner layer 8 of the expansion bag is small, Due to the thickness of the outer layer 7 of the expansion bag, the middle layer pressure expansion bag 4 expands inward, that is, towards the inner layer 8 of the expansion bag, and then squeezes the inner layer 5 of the pressure belt, and squeezes the user's legs. By pushing the elliptical inflatable bag 17, the contact area between the Velcro hook surface 18 and the Velcro velvet surface 19, the leg tightening force is adjusted. The silicone elastic ring 16 is used to increase the elastic force of the elliptical inflatable bag 17, so that the subsequent user can pull the inner pull tab 15 and the outer pull tab 14 to separate the Velcro hook surface 18 and the Velcro velvet surface 19, and the elliptical inflatable bag 17 is reset.

[0041] Specifically, if Figure 2 and Figure 3As shown, a one-way air valve 9 is embedded and connected to the outside of the pressure belt body 1 at a position corresponding to the passive extrusion airbag 2, and the one-way air valve 9 is connected to the passive extrusion airbag 2. The leg massage belt 6 includes a massage bag strip 10 with an arc-shaped structure design, and a connecting air pipe 13 is fixed between adjacent massage bag strips 10. The massage bag strip 10 is fixed to the inner wall of the pressure belt inner layer 5, and massage magnetic beads 12 are fixed at equal distances on the side of the massage bag strip 10 away from the pressure belt inner layer 5, and heat dissipation jet holes 11 are opened between adjacent massage magnetic beads 12.

[0042] By adopting the above technical solution, the user then wears the pressure belt main body 1 and, during walking, intermittently presses the passive compression airbag 2 on the inner side of the knee joint as the angle of the user's knee joint changes. When the passive compression airbag 2 is pressed, the internal air is transported to the massage bag strip 10 in the leg massage belt 6. The massage bag strip 10 expands instantly, driving the massage magnetic beads 12 fixed on the massage bag strip 10 to contact the user's leg skin, forming acupoint pressing and promoting blood circulation. Then, the air inside the massage bag strip 10 gradually passes through the heat dissipation jet holes 11 to spray the gas onto the user's leg skin, thereby increasing the air flow inside the pressure belt main body 1 in contact with the user's skin, reducing the stuffy discomfort when wearing in summer, and also reducing the generation of sweat stains and bacteria. After the passive compression airbag 2 is no longer squeezed by the knee joint, it is replenished by sucking in external air through the one-way air valve 9.

[0043] Working principle: When working, the user takes the pressure belt body 1 and wears it on the user's leg. The user pulls the pressure belt body 1 upward along the leg to position the passive squeezing airbag 2 on the inner side of the user's knee joint. At this time, the passive squeezing airbag 2 fits the inner side of the user's knee joint. Then the user presses the outer side of the belt body according to the wearing comfort and the required tightening pressure of the pressure belt body 1 on the leg, and presses the elliptical inflatable bag 17. The user slowly pushes and presses along the edges of both ends of the elliptical inflatable bag 17 toward the center of the elliptical inflatable bag 17 with both hands. During the pushing and pressing process, the Velcro suede surface 19 in the elliptical inflatable bag 17 contacts and is fixed with the Velcro hook surface 18, and the elliptical inflatable bag 17 is squeezed. , the internal gas is transported to the middle-layer pressure expansion bag 4, and the middle-layer pressure expansion bag 4 expands. Since the thickness of the inner layer 8 of the expansion bag is less than the thickness of the outer layer 7 of the expansion bag, the middle-layer pressure expansion bag 4 expands inward, that is, in the direction of the inner layer 8 of the expansion bag, and then squeezes the inner layer 5 of the pressure belt, and squeezes the user's legs. By pushing the distance of the elliptical airbag 17 and the contact area between the Velcro hook surface 18 and the Velcro velvet surface 19, the leg tightening force is adjusted. The silicone elastic ring 16 is to increase the elastic force of the elliptical airbag 17, so that the subsequent user can pull the inner pull tab 15 and the outer pull tab 14 to separate the Velcro hook surface 18 and the Velcro velvet surface 19, and the elliptical airbag 17 is reset;

[0044] Subsequently, the user wears the pressure belt body 1 and, during walking, the passive compression airbag 2 on the inner side of the knee joint is intermittently pressed as the angle of the user's knee joint changes. When the passive compression airbag 2 is pressed, the internal air is transported to the massage bag strip 10 in the leg massage belt 6. The massage bag strip 10 expands instantly, driving the massage magnetic beads 12 fixed on the massage bag strip 10 to contact the user's leg skin, forming acupoint pressing and promoting blood circulation. Then the air inside the massage bag strip 10 gradually passes through the heat dissipation jet holes 11 to spray the gas onto the user's leg skin, thereby increasing the air flow inside the pressure belt body 1 in contact with the user's skin, reducing the stuffy discomfort when wearing it in summer, and also reducing the generation of sweat stains and bacteria. After the passive compression airbag 2 is no longer squeezed by the knee joint, it is replenished by sucking in external air through the one-way air valve 9.
