[0054] After long flights, trains, or car rides, legs and feet can become numb and swollen. Medical experts are now reminding people that swelling during long-distance travel should be a sign of lower extremity venous thrombosis. Therefore, leg massage is crucial to prevent venous thrombosis after long public transportation and for those who are bedridden for extended periods.

[0055] In related art, venous thrombosis is treated and prevented by using anti-thrombotic devices. The anti-thrombotic devices include limb pressure sleeves with air bags installed inside. By inflating and deflating the air bags, circulatory pressure is applied to the limbs, thereby achieving limb massage.

[0056] Limb pressure cuffs of related technologies are mostly used for treatment with low pressure parameters, such as 45 mmHg and 90 mmHg; they cannot be adapted to the clinical treatment pressure range, and thus cannot be used with antithrombotic devices that output different pressure parameters.

[0057] The researchers who developed this application discovered that the airbag structure in the related art is weak and prone to leakage. Especially when high-pressure treatment is required, the pressure inside the airbag is high, and after repeated use, the airbag is prone to damage and leakage, failing to achieve the desired pressure treatment effect. Furthermore, the limb pressure cuff can become unusable due to leakage.

[0058] In view of this, the present application has developed and designed a new limb pressure sleeve, which forms ribs on the pressurized airbag to improve the structural strength of the pressurized airbag; and by setting multiple ribs, the total area of ​​the multiple ribs is greater than or equal to 4% of the area of ​​the pressurized airbag, thereby increasing the inflation pressure and the number of inflation and deflation cycles that the pressurized airbag can withstand, ensuring that the limb pressure sleeve still has stable performance under high pressure parameters and ensuring the therapeutic effect.

[0059] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0060] Combine Figure 1 and Figure 2 , an embodiment of the present application provides a limb pressure sleeve, which includes: a pressure sleeve body 100. The pressure sleeve body 100 plays the role of covering the limb.

[0061] The pressure sleeve body 100 has a first side and a second side along its width direction, Figure 1 and Figure 2 , the pressure jacket body 100 has a left side and a right side along its width direction.

[0062] When the limb pressure sleeve is placed on a limb, the length direction of the pressure sleeve body 100 corresponds to the length direction of the human lower limb; the width direction of the pressure sleeve body 100 corresponds to the circumference direction of the human lower limb.

[0063] The first side and the second side of the pressure sleeve body 100 are detachably connected so that the pressure sleeve body 100 can be placed outside the limb. When the first side and the second side of the pressure sleeve body 100 are disconnected, the pressure sleeve body 100 is generally in the form of a sheet and can be removed from the limb.

[0064] There are many ways to detachably connect the first side and the second side of the pressure sleeve body 100. For example, the first side and the second side of the pressure sleeve body 100 are connected by snaps; for another example, the first side and the second side of the pressure sleeve body 100 are connected by a zipper; for another example, the first side and the second side of the pressure sleeve body 100 are connected by a strap; for another example, the first side and the second side of the pressure sleeve body 100 are connected by a magnetic buckle, etc.

[0065] In the embodiment of the present application, the first side and the second side of the pressure sleeve body 100 are bonded by Velcro 400. Such a setting can make the connection between the first side and the second side of the pressure sleeve body 100 stable and the assembly and disassembly simple and convenient. In addition, the Velcro 400 has a sheet structure, which is conducive to maintaining the sheet structure of the pressure sleeve body 100, without local protrusions, and highly comfortable.

[0066] In the embodiment of the present application, the limb pressure sleeve further includes a pressurized airbag 200, which is fixed to the pressure sleeve body 100. The pressurized airbag 200 is configured to inflate to compress the covered limb; alternatively, the pressurized airbag 200 is configured to deflate to release the pressure applied to the limb. This repeated inflation and deflation provides a massage effect on the limb, promotes blood circulation, and prevents the formation of venous thrombosis.

[0067] In some embodiments, the pressure sleeve body 100 is provided with multiple pressurized airbags 200, which are sequentially arranged along the length of the pressure sleeve body 100. Multiple Velcro strips 400 are provided, with one Velcro strip 400 provided at the end of each pressurized airbag 200. This helps improve the reliability of the connection between the two sides of the pressure sleeve body 100 and reduces the possibility of the two sides of the pressure sleeve body 100 collapsing when the pressurized airbags 200 are inflated.

[0068] In some embodiments, the thickness of the wall of the pressurized airbag 200 is greater than or equal to 1.5 mm, ensuring the wall thickness and pressure-bearing capacity of the pressurized airbag.

[0069] In some embodiments, the pressurized airbag 200 is an elastic airbag having elastic deformation capability to improve pressure bearing capacity.

[0070] For example, the material of the pressurized airbag 200 can be elastic materials such as TPU (Thermoplastic Polyurethane), PVC (Polyvinyl Chloride), and PU (Polyurethane).

[0071] Combine Figure 3 In some embodiments, the pressurized airbag 200 includes a bag body 230 and a connecting piece 240 located at the edge of the bag body 230 , and the bag body 230 is configured to form an air cavity.

[0072] Combine Figure 4 The capsule 230 is pressed and connected along the thickness direction of the pressure sleeve body to form the rib 210. The two sub-cavities 220 separated by the rib 210 are connected. Figure 1 and Figure 2 .

[0073] The connecting piece 240 is fixedly connected with the pressure sleeve body 100, so as to fix the pressurized air bag 200 on the pressure sleeve body 100. The connecting piece 240 and the pressure sleeve body 100 can be bonded, sewn, heat-welded, or the like.

[0074] In this way, the air in the air bag 200 is inflated or deflated by the air bag body 230, and the connecting piece 240 is arranged at the edge of the air bag body 230 to be fixedly connected with the pressure sleeve body 100, so as to ensure the stability of the connection between the pressurized air bag 200 and the pressure sleeve body 100, and does not affect the inflation or deflation of the pressurized air bag 200.

[0075] Continuing to refer to Figure 3 The pressurized air bag 200 comprises a first elastic bag piece 231 and a second elastic bag piece 232, which are oppositely arranged along the thickness direction of the pressure sleeve body 100, and have a space between the first elastic bag piece 231 and the second elastic bag piece 232 to form the air bag body 230.

[0076] The first elastic bag piece 231 and the second elastic bag piece 232 are elastic, so as to form the air bag body 230 with elasticity, which is beneficial to improve the pressure bearing capacity and the puncture resistance of the air bag body 230, and improve the structural strength of the pressurized air bag 200.

[0077] The portions of the first elastic bag piece 231 and the second elastic bag piece 232 outside the air bag body 230 are sealingly connected to form the connecting piece 240, so that the pressurized air bag 200 is an integrally formed unit, has good sealing performance, and is beneficial to improve the pressure bearing capacity.

[0078] The first elastic bag piece 231 and the second elastic bag piece 232 can be fixedly connected by bonding or welding to achieve the sealing effect. The welding can be high-frequency welding.

[0079] In combination with Figure 4 The first elastic bag piece 231 and the second elastic bag piece 232 in the partial region of the air bag body 230 are press-bonded to form the rib 210.

[0080] In the embodiment, the pressurized air bag 200 is press-bonded along the thickness direction of the pressure sleeve body 100 to form the rib 210, so as to form a plurality of communicating sub-cavities 220 in the structure of the pressurized air bag 200.

[0081] In this way, the rib 210 is formed by press-bonding the body of the pressurized air bag 200, which is beneficial to improve the pressure bearing capacity of the pressurized air bag 200.

[0082] The embodiment of the present application forms ribs 210 on the pressurized airbag 200, so that the pressurized airbag 200 is structured to form multiple interconnected sub-cavities 220, which can make the pressure distribution more uniform. Moreover, during the inflation and deflation process, the pressure of the sub-cavity 220 increases or decreases according to the flow direction of the airflow, thereby achieving a rhythmic massage method, which is beneficial to improving the anti-thrombotic effect.

[0083] Among them, there are multiple ribs 210, and the multiple ribs 210 can be arranged at intervals along the length direction of the pressure sleeve body 100, the multiple ribs 210 can also be arranged at intervals along the width direction of the pressure sleeve body 100, and the multiple ribs 210 can also be arranged at intervals along the inclined direction, and the inclined direction intersects with the length direction and the width direction respectively.

[0084] The plurality of ribs 210 may be arranged in parallel, and the extension directions of the plurality of ribs 210 may intersect; the plurality of ribs 210 may also intersect.

[0085] The ribs 210 can be in the form of elongated strips, such as straight strips, curved strips, arc-shaped strips, or wavy strips. The ribs 210 can also be in the form of ellipses, circles, or the like, with a larger area and smoother edges, thereby increasing the structural strength of the ribs 210 and reducing the possibility of air leakage due to concentrated force at the edges of the ribs 210.

[0086] Generally, the ends of the ribs 210 are susceptible to concentrated stress, and are more likely to be damaged and leak.

[0087] To this end, in some embodiments, such as Figure 1 As shown, the rib 210 includes a straight portion 211 and a head 212 connected to both ends of the straight portion 211 . The width of the head 212 is greater than that of the straight portion 211 . This configuration is beneficial to improving the structural strength of the head 212 .

[0088] The width of the ribs 210 is related to the force applied to the pressurized airbag 200 and the processing power of the equipment. If the ribs 210 are less than 1.5 mm wide, the pressurized airbag 200 is easily ruptured by inflation. If the ribs 210 are wider than 10 mm, the processing equipment must have a high processing power, resulting in low product yield. Therefore, the width of the straight portion 211 is less than or equal to 10 mm; alternatively, the width of the straight portion 211 ranges from 1.5 mm to 10 mm.

[0089] In the embodiment of the present application, the total area of ​​the plurality of ribs 210 is greater than or equal to 4% of the area of ​​the pressurized airbag 200. The total area of ​​the plurality of ribs 210 is the sum of the areas of all ribs 210 on a pressurized airbag 200; the area of ​​a pressurized airbag 200 is the area of ​​the pressurized airbag 200 in a flat state when the pressurized airbag 200 is not inflated.

[0090] By providing more ribs 210 , the structural strength of the pressurized airbag 200 is improved, the pressure on the pressurized airbag 200 is dispersed, and the possibility of leakage due to excessive local pressure is reduced.

[0091] The total tensile force on the pressurized airbag 200 is the inflation pressure multiplied by the area of ​​the pressurized airbag 200. The force applied at the ends of the ribs 210 can be further calculated. Leakage within the pressurized airbag 200 is most likely concentrated at the ends of the ribs 210. For safety and reliability, this force should be less than one-third of the tensile strength of the airbag or the welding force per unit length. Furthermore, the total area of ​​all ribs 210 must account for no less than 4% of the area of ​​the pressurized airbag 200.

[0092] right Figure 1 and Figure 2 Multiple limb pressure sleeves shown, with Figure 5 Shown are multiple limbs where pressure cuffs were tested.

[0093] in, Figure 5 The total area of ​​the plurality of ribs 210 in the mid-limb pressure sleeve is less than 4%. Test conditions: the inflation pressure is 300 mmHg. Figure 5 The limb pressure sleeve shown leaked after only about 100 cycles of inflation and deflation at an inflation pressure of 300 mmHg, and could not meet the requirements of cyclic use.

[0094] Embodiments of the present application Figure 1 and Figure 2 The limb pressure sleeve shown has a total area of ​​multiple ribs 210 greater than or equal to 4% of the area of ​​the pressurized airbag 200. Under an inflation pressure of 300 mmHg, it can still be used normally without leakage after 50,000 cycles of inflation and deflation.

[0095] In some embodiments, when the size of the ribs 210 is determined, 4% of the area of ​​the pressurized airbag 200 is divided by the area of ​​a single rib 210 to determine the number of ribs 210 in a single pressurized airbag 200 .

[0096] Combine Figure 6 In some embodiments, the pressure sleeve body 100 includes a first sheet 110 and a second sheet 120 , the first sheet 110 and the second sheet 120 are stacked along the thickness direction of the pressure sleeve body 100 , and the first sheet 110 is configured to face the limb;

[0097] There is a gap between the first sheet 110 and the second sheet 120 so that the pressurized airbag 200 can be accommodated between the first sheet 110 and the second sheet 120 .

[0098] In other areas outside the pressurized airbag 200, the first sheet 110 and the second sheet 120 may be fixedly connected to improve the structural strength of the pressure sleeve body 100. For example, the first sheet 110 and the second sheet 120 may be sewn or bonded.

[0099] The pressure sleeve body 100 of the embodiment of the present application hides the pressurized airbag 200 inside the pressure sleeve body 100 by setting the first sheet 110 and the second sheet 120, thereby protecting the pressurized airbag 200; and by setting the materials of the first sheet 110 and the second sheet 120, the comfort of physical contact can be improved and the aesthetic appearance can be improved.

[0100] In some embodiments, along the thickness direction of the pressure sleeve body 100 , there is a gap between the first sheet 110 and the rib 210 opposite thereto, that is, the first sheet 110 is separated from the rib 210 , so that the rib 210 is not displayed on the inner surface of the pressure sleeve body 100 .

[0101] In some embodiments, reference Figure 7 The first sheet 110 is connected to the rib 210, so that the rib 210 can be visible on the surface of the first sheet 110 of the pressure sleeve body 100, making it easier for the pressurized airbag 200 to better contact the limb; moreover, it can also increase the structural strength of the rib 210 and reduce the risk of air leakage at the rib 210.

[0102] In some embodiments, along the thickness direction of the pressure sleeve body 100 , the second sheet 120 and the rib 210 opposite thereto are spaced apart, that is, the second sheet 120 is separated from the rib 210 , so that the rib 210 is not displayed on the outer surface of the pressure sleeve body 100 .

[0103] In some embodiments, reference Figure 7 The second sheet 120 is connected to the rib 210, so that the rib 210 can be visible on the surface of the second sheet 120 of the pressure sleeve body 100, making it easier for users to better observe the inflation and deflation effects of the pressurized airbag 200; moreover, it can also increase the structural strength of the rib 210 and reduce the risk of air leakage at the rib 210.

[0104] The inner surface of the pressure sleeve body 100 is the surface in contact with the limb, and the outer surface of the pressure sleeve body 100 is the surface away from the limb.

[0105] In some embodiments, the connecting piece 240 is located between the first piece 110 and the second piece 120 , and the connecting piece 240 is fixedly connected to the first piece 110 and the second piece 120 .

[0106] The connection methods of the connecting piece 240 to the first piece 110 and the second piece 120 include, but are not limited to, bonding, sewing, hot-melt connection, and the like.

[0107] By clamping and fixing the connecting piece 240 between the first piece 110 and the second piece 120, the connecting piece 240 can be protected and the stability and reliability of the fixing of the connecting piece 240 can be improved, thereby reducing the problem of the connecting piece 240 being damaged and extending to the bag body 230, thereby affecting the stability of the pressurized airbag 200.

[0108] In some embodiments, the limb pressure sleeve 10 includes at least two composite sheets, wherein the composite sheet is formed by a fabric layer and an elastic layer;

[0109] Parts of the two layers of composite sheets are connected as a whole to form the pressure sleeve body 100 ; and other parts of the two layers of composite sheets are spaced apart to form the pressurized airbag 200 .

[0110] For example, the elastic layer can be made of an elastic material such as TPU, PVC, or PU. The composite sheet can be formed by laminating the elastic layer and the fabric layer via post-lamination or online lamination. The post-lamination method involves first forming the elastic material into a film and then gluing and laminating it to the fabric. The online lamination method involves directly casting the elastic material onto the fabric after applying glue or without gluing to form the composite sheet.

[0111] Such a configuration can enhance the structural strength of the pressure sleeve body 100 and also improve the pressure-bearing range of the pressurized airbag 200 .

[0112] In some embodiments, the first sheet 110 and the bladder body 230 are bonded or heat-melted together to improve the reliability of the connection between the pressurized airbag 200 and the pressure sleeve body 100, and also to improve the structural strength and pressure-bearing capacity of the bladder body 230.

[0113] Of course, in some embodiments, the first sheet 110 and the capsule 230 are separated and not connected.

[0114] In some embodiments, the second sheet 120 and the bladder body 230 are bonded or heat-melted together to improve the reliability of the connection between the pressurized airbag 200 and the pressure sleeve body 100, and also to improve the structural strength and pressure-bearing capacity of the bladder body 230.

[0115] Of course, in some embodiments, the second sheet 120 and the capsule 230 are separated and not connected.

[0116] Continue to refer to Figure 1 and Figure 2 In some embodiments, the pressurized airbag 200 includes a front region 250 and a rear region 260 , and the front region 250 and the rear region 260 are arranged side by side along the width direction of the sleeve body.

[0117] It should be noted that in Figure 1 In the figure, the dotted area only defines the relative positions of the front area 250 and the rear area 260 , and does not demarcate the front area 250 and the rear area 260 .

[0118] When the limb pressure sleeve 10 is arranged around the outside of the limb, the front area 250 of the pressurized airbag 200 corresponds to the front side of the limb, and performs pressure massage on the front side of the limb; the rear area 260 of the pressurized airbag 200 corresponds to the rear side of the limb, and performs pressure massage on the rear side of the limb.

[0119] A plurality of ribs 210 are formed in the rear region 260 , and the plurality of ribs 210 are arranged at intervals along the width direction of the pressure sleeve body 100 in the rear region 260 .

[0120] Among them, the multiple ribs 210 in the rear side area 260 have two ends along the length direction of the pressure sleeve body 100, wherein the multiple ribs 210 in the rear side area 260 can extend along the length direction of the pressure sleeve body 100, or the multiple ribs 210 in the rear side area 260 can be inclined at a certain angle relative to the length direction of the pressure sleeve body 100.

[0121] The ribs 210 in the rear area 260 may be straight ribs 210 extending along a set direction, or may be curved ribs 210 , for example, the ribs 210 in the rear area 260 may be arcuate ribs 210 .

[0122] A plurality of ribs 210 are formed in the front region 250 , and the plurality of ribs 210 are arranged at intervals along the length direction of the pressure sleeve body 100 in the front region 250 .

[0123] Among them, the multiple ribs 210 in the front side area 250 have two ends along the width direction of the pressure sleeve body 100, wherein the multiple ribs 210 in the front side area 250 can extend along the length direction of the pressure sleeve body 100, or the multiple ribs 210 in the front side area 250 can be inclined at a certain angle relative to the length direction of the pressure sleeve body 100.

[0124] The ribs 210 in the front area 250 may be straight ribs 210 extending along a set direction, or may be curved ribs 210 , for example, the ribs 210 in the front area 250 may be arcuate ribs 210 .

[0125] Since the blood is mainly concentrated on the back side of the limb, the muscle is squeezed by the rib 210 of the back side area 260, which can prevent the problem of blood concentration caused by zero pressure area and ensure the balance of the back side area 260 of the limb, which is beneficial to the accelerated flow of squeezed blood. The front side of the limb is mainly bone and less muscle, and the blood can be accelerated to flow backward by transverse inflation and squeezing.

[0126] In some embodiments, the plurality of ribs 210 are uniformly spaced in the width direction of the pressure sleeve body 100 in the back side area 260 to form a first rib assembly 261. In this way, the plurality of ribs 210 are uniformly spaced, so that the inflation height of the sub-cavity 220 between the two adjacent ribs 210 is consistent, which is beneficial to improve the uniformity of the muscle squeezing force.

[0127] Among them, the plurality of ribs 210 in the first rib assembly 261 can extend in the length direction of the pressure sleeve body 100.

[0128] In some embodiments, as shown in Figure 1 and Figure 2 , the rib 210 in the back side area 260 is a continuous integral strip, and the inflation bulging height of the pressurized air bag 200 is larger in this way, which is beneficial to improve the squeezing force of the limb.

[0129] In some embodiments, referring to Figure 8 , the rib 210 in the back side area 260 includes a plurality of sub-strips 213, which are spaced apart along the extension direction of the sub-strip 213, and the spacing between the two adjacent sub-strips 213 is less than or equal to 8mm. In this way, the area of the sub-cavity 220 can be smaller, which is beneficial to rapid inflation and deflation.

[0130] Continuing to refer to Figure 1 and Figure 2 , the plurality of ribs 210 are uniformly spaced in the length direction of the pressure sleeve body 100 in the front side area 250 to form a second rib assembly 251. In this way, the plurality of ribs 210 are uniformly spaced, so that the inflation height of the sub-cavity 220 between the two adjacent ribs 210 is consistent, which is beneficial to improve the uniformity of the muscle squeezing force.

[0131] Among them, the plurality of ribs 210 in the second rib assembly 251 can extend in the width direction of the pressure sleeve body 100.

[0132] Among them, the difference between the spacing of the two adjacent ribs 210 in the first rib assembly 261 and the spacing of the two adjacent ribs 210 in the second rib assembly 251 is less than or equal to 10mm.

[0133] Illustratively, the distance between two adjacent ribs 210 in the first rib assembly 261 is the same as the distance between two adjacent ribs 210 in the second rib assembly 251 .

[0134] By configuring in this manner, the embodiment of the present application can reduce the height of the pressurized airbag 200 when inflated, shorten the inflation time, and quickly squeeze the user's muscles.

[0135] In some embodiments, combined Figure 2 There is a first interval L1 between two adjacent ribs 210 in the first rib assembly 261.

[0136] A second interval L2 is defined between the first rib assembly 261 and the end of the rib 210 in the front region 250 .

[0137] A third interval L3 is formed between the side of the first rib assembly 261 facing away from the front region 250 and the side edge of the adjacent pressurized airbag 200 .

[0138] A difference between any two of the first interval L1 , the second interval L2 , and the third interval L3 is less than or equal to 10 mm.

[0139] Such a setting can make the area difference of the sub-cavity 220 in the first rib assembly 261 and the sub-cavities 220 on both sides of the first rib assembly 261 smaller, so that the difference in the inflated height of these sub-cavities 220 is not large, which is conducive to ensuring the balance of the force of squeezing the muscles.

[0140] In some embodiments, the second interval L2 is less than or equal to 70 mm. For example, the second interval L2 ranges from 10 mm to 40 mm. This configuration allows the pressurized airbag 200 to withstand greater inflation pressure, reducing the risk of damage caused by inflation pressure.

[0141] If the third interval L3 is smaller than 8 mm, the limb pressure sleeve 10 may be deformed and wrinkled when worn on the limb, and inflation and deflation may be slow and unsmooth, or even cause the gas to be unable to flow quickly.

[0142] If the third interval L3 is greater than 45 mm, the bulging heights at both ends of the rib 210 are too large. During repeated cycles of inflation and deflation, the rib 210 may be gradually deformed or even ruptured beyond the limit of deformation, resulting in air leakage.

[0143] Therefore, in some embodiments, the third interval L3 ranges from 8 mm to 45 mm. This ensures smooth inflation and deflation, and reduces the risk of excessive local bulging of the pressurized airbag 200 exceeding the stress strength at the rib 210 and causing damage.

[0144] Continue to refer to Figure 2In some embodiments, there is a fourth interval L4 between two adjacent ribs 210 in the second rib assembly 251.

[0145] The pressurized air bag 200 has a first side edge and a second side edge opposite to each other along the length direction of the pressure sleeve body 100. The second rib assembly 251 is spaced apart from the first side edge by a fifth interval L5. The second rib assembly 251 is spaced apart from the second side edge by a sixth interval L6.

[0146] When the interval between the second rib assembly 251 and the edge of the pressurized air bag 200 is less than 8 mm, the pressurized air bag 200 is inflated and deformed by the body pressure sleeve 10, and the inflation and deflation of the pressurized air bag 200 is not smooth, and even the gas cannot flow quickly.

[0147] When the interval between the second rib assembly 251 and the edge of the pressurized air bag 200 is greater than 45 mm, the bulging height of the two ends of the rib 210 is too large, and the position of the rib 210 is gradually deformed when the pressurized air bag 200 is repeatedly inflated and deflated, and even the rib 210 is broken due to excessive deformation.

[0148] Therefore, in some embodiments, the fifth interval L5 is in the range of 8 mm to 45 mm, and the sixth interval L6 is in the range of 8 mm to 45 mm. In this way, the inflation and deflation of the pressurized air bag 200 can be smooth, and the local bulging height of the pressurized air bag 200 can be reduced, which can prevent the pressurized air bag 200 from being damaged due to excessive stress on the rib 210.

[0149] When the width between the first side edge and the second side edge of the pressurized air bag 200 is determined, the length of the rib 210 can be determined by subtracting 16 mm to 90 mm.

[0150] The difference between any two of the fourth interval L4, the fifth interval L5, and the sixth interval L6 is less than or equal to 10 mm.

[0151] In this way, the sub-cavities 220 in the second rib assembly 251 and the sub-cavities 220 on both sides of the second rib assembly 251 have a small difference in area, so that the bulging height of the sub-cavities 220 is not greatly different, which is beneficial to ensure the balance of the muscle pressing force.

[0152] Continuing to refer to Figure 1 and Figure 2 The body pressure sleeve 10 further comprises an air nozzle 300, which is in sealing connection with the pressurized air bag 200. The air nozzle 300 is configured to inflate the pressurized air bag 200, or the gas in the pressurized air bag 200 is released outward through the air nozzle 300. The air nozzle 300 and the pressurized air bag 200 can be connected by welding, and the connection and sealing are reliable.

[0153] In some embodiments, the air nozzle 300 and the pressurized airbag 200 are integrally formed as a single piece, so as to improve the airtightness of the pressurized airbag 200 .

[0154] The air nozzle 300 is connected to the chamber of the pressurized airbag 200 and is located at the end of the rear region 260 away from the front region 250. This arrangement allows the air nozzle 300 to inflate the rear region 260 first, and then the air spreads to the front region 250, which is conducive to improving the massage and relief effect.

[0155] In some embodiments, there is a seventh interval L7 between the air nozzle 300 and the adjacent rib 210. The seventh interval L7 is less than or equal to 70 mm, for example, the seventh interval L7 ranges from 10 mm to 40 mm.

[0156] This arrangement ensures a certain distance between the air nozzle 300 and the rib 210 , thereby preventing the air nozzle 300 from being damaged due to the stress caused by inflation when the distance between the air nozzle 300 and the rib 210 is too small.

[0157] Through the above-mentioned configuration, the limb pressure sleeve 10 of the embodiment of the present application can be adapted to anti-thrombotic devices with different treatment parameters, and has a wider scope of application.

[0158] The limb pressure sleeve 10 of the embodiment of the present application can be adapted for repeated use in anti-thrombotic devices with low treatment parameters (the inflation pressure of the pressurized airbag 200 is not greater than 90 mmHg).

[0159] The limb pressure sleeve 10 of the embodiment of the present application can be adapted for repeated use with anti-thrombotic devices having medium treatment parameters (the inflation pressure of the pressurized airbag 200 is not greater than 200 mmHg).

[0160] The limb pressure sleeve 10 of the embodiment of the present application can be adapted for repeated use with anti-thrombotic devices having high treatment parameters (the inflation pressure of the pressurized airbag 200 is not greater than 300 mmHg).

[0161] Continue to refer to Figure 1 The limb pressure sleeve 10 also includes an airway tube 310 , which is connected to the air nozzle 300 .

[0162] The limb pressure sleeve 10 further includes a connector 320 , to which all the airway tubes 310 are connected. The connector 320 is configured to communicate with the anti-thrombotic device host 20 to inflate or deflate the pressurized airbag 200 through the airway tubes 310 .

[0163] In the embodiment of the present application, a connector 320 is provided for all the airway tubes 310 , thereby facilitating the assembly and disassembly of the airway tubes 310 and the anti-thrombotic device host 20 and improving the assembly and disassembly efficiency.

[0164] Continue to refer to Figure 1 In some embodiments of the present application, a limiting portion 180 is provided on the pressure sleeve body 100, and the limiting portion 180 is constructed to limit the air guide tube 310. Such a setting can centrally limit multiple air guide tubes 310, so that the air guide tubes 310 extend in a set direction, which can make the air guide tubes 310 extend more straight to reduce the flow resistance of the gas; it can also help to reduce the length of the air guide tubes 310, thereby helping to reduce costs.

[0165] In addition, by providing the limiting portion 180 , the plurality of air guide tubes 310 are centrally restricted, which helps to ensure the stability of the connection head 320 .

[0166] Furthermore, the limiting portion 180 is provided to restrict the air duct 310 , thereby reducing the possibility of the air duct 310 being pulled and damaged.

[0167] In some embodiments, a plurality of limiting portions 180 are arranged at intervals along the length direction of the pressure sleeve body 100 to enhance the limiting effect on the airway tube 310 .

[0168] Continue to refer to Figure 1 and Figure 2 The pressure sleeve body 100 includes a calf sleeve portion 140 , which is provided with at least one pressurized airbag 200 . The calf sleeve portion 140 is configured to be sleeved outside the calf.

[0169] Illustratively, the calf sleeve 140 is provided with one pressurized airbag 200 , or the calf sleeve 140 may be provided with a plurality of pressurized airbags 200 , for example, two or three.

[0170] The pressure sleeve body 100 includes a thigh sleeve portion 130, and the thigh sleeve portion 130 and the calf sleeve portion 140 are arranged in sequence along the length direction of the pressure sleeve body 100; the thigh sleeve portion 130 is provided with at least one pressurized airbag 200, and the thigh sleeve portion 130 is constructed to be sleeved outside the thigh.

[0171] In some embodiments, the thigh sleeve portion 130 and the calf sleeve portion 140 are arranged side by side along the length of the pressure sleeve body 100 .

[0172] In this way, the limb pressure sleeve 10 can perform pressure massage on the thigh and calf at the same time, and because the pressurized airbags 200 of the thigh sleeve 130 and the calf sleeve 140 are independently provided, it is also possible to selectively massage only the thigh or the calf, which is more flexible to use.

[0173] In some embodiments, a first connecting portion 160 is provided between the thigh sleeve portion 130 and the calf sleeve portion 140 to adapt to the connection between the thigh and the calf, making the limb pressure sleeve 10 more comfortable to wear.

[0174] The first connecting portion 160 is provided with a first through hole 161. The first through hole 161 can be an elongated hole extending along the width direction of the pressure sleeve body 100, such as a waist-shaped hole, a rectangular hole, an elliptical hole, etc. The provision of the first through hole 161 can provide more folding space for the first connecting portion 160, reducing the discomfort caused by the first connecting portion 160 folding and stacking when bent between the thigh and calf; it can also increase the extension space to accommodate the extension of the thigh and calf when straightened; in addition, by providing the first through hole 161, the adaptability range of the limb pressure sleeve 10 can be increased to accommodate patients of different sizes.

[0175] In addition, the first through hole 161 provided at the first connecting portion 160 can also serve as a ventilation function and can also reduce material usage, thereby helping to reduce costs.

[0176] After the limb pressure sleeve 10 is worn, the first through hole 161 corresponds to the popliteal fossa of the human body, which is the connection between the thigh and the back of the calf.

[0177] In some embodiments, ventilation holes 141 are provided on the calf sleeve 140 to further increase the breathability of the calf sleeve 140 .

[0178] When the calf sleeve 140 is provided with two pressurized airbags 200, the ventilation hole 141 is provided between the two pressurized airbags 200. Since the pressurized airbags 200 are closely attached to the calf and have poor air permeability, providing the ventilation hole 141 between the two pressurized airbags 200 does not affect the fit and support of the pressurized airbags 200 against the calf, but also improves the air permeability of the calf sleeve 140.

[0179] Combine Figure 9 and Figure 10 The pressure sleeve body 100 further includes a foot sleeve portion 150, which is disposed on the side of the calf sleeve portion 140 away from the thigh sleeve portion 130. The foot sleeve portion 150 is provided with at least one pressurized air bag 200, and the foot sleeve portion 150 is configured to be sleeved outside the foot.

[0180] Such an arrangement can perform pressurized massage on the thigh, calf and foot respectively. Two pressurized airbags 200 are arranged on the calf sleeve 140 to perform pressurized massage on the longer calf. One pressurized airbag 200 is arranged on the thigh sleeve 130 to ensure pressurized massage on the thigh and avoid the pressurized airbag 200 being too close to the thigh root and affecting comfort.

[0181] In some embodiments of the present application, a second connecting portion 170 is provided between the calf sleeve portion 140 and the foot sleeve portion 150 to adapt to the portion between the calf and the foot, making the limb pressure sleeve 10 more comfortable to wear.

[0182] The second connecting portion 170 is provided with a second through hole 171, thereby providing more fold space for the second connecting portion 170; when the limb pressure sleeve 10 is arranged around the outside of the limb, the second through hole 171 corresponds to the heel portion to adapt to patients with different sizes of feet, thereby improving the applicability of the limb pressure sleeve 10.

[0183] In some embodiments, the second through hole 171 is an elongated hole extending along the length direction of the pressure sleeve body 100, for example, a waist-shaped hole, a rectangular hole, an elliptical hole, etc.

[0184] Such a setting allows the patient to adjust the position of the heel in the extension direction of the second through hole 171 according to his own situation to adapt to feet of different sizes; it can also make the limb pressure sleeve 10 fit better with the limb, reduce the sliding and positioning of the limb pressure sleeve 10 in the heel area, and ensure the stability and comfort of the limb pressure sleeve 10.

[0185] Continue to refer to Figures 11 to 13 An embodiment of the present application also provides an anti-thrombotic system, which includes the limb pressure sleeve 10 of the above embodiment and an anti-thrombotic device host 20. The anti-thrombotic device host 20 is connected to the pressurized airbag 200 of the limb pressure sleeve 10 and is configured to inflate or deflate the pressurized airbag 200.

[0186] The structure, function and effect of the limb pressure sleeve provided in this embodiment are the same as those of the above embodiment. Please refer to the above embodiment for details and will not be described again here.

[0187] In some embodiments, the anti-thrombotic device host 20 is connected to the pressurized airbag 200 of the limb pressure cuff 10 via an airway tube 310 .

[0188] In other embodiments, Figure 11 As shown, the main unit 20 of the anti-thrombotic device is connected to the pressurized airbag 200 of the limb pressure sleeve 10 through an additional intermediate tube 30, so that there is a larger distance between the main unit 20 of the anti-thrombotic device and the limb pressure sleeve 10, thereby improving the flexibility of the user in using the position of the limb pressure sleeve 10.

[0189] Combine Figure 12 In some embodiments, a display device 21 is provided on the front side of the anti-thrombotic device host 20. The display device 21 is configured to display the working parameters of the anti-thrombotic system, etc., so that the user can easily obtain the current working status of the anti-thrombotic system.

[0190] In some embodiments, the display device 21 may be a touch screen, and the user may also control the working state of the anti-thrombotic device host 20 through the touch screen.

[0191] Combine Figure 13In some embodiments, the rear side of the anti-thrombus device host 20 is provided with a connecting port 22, which is communicated with the air guide pipe through the intermediate pipe 30, so as to inflate or deflate the pressurized air bag. Moreover, the connecting port 22 is located at the rear side of the anti-thrombus device host 20, which reduces the possibility of touching the intermediate pipe 30 or the air guide pipe during use, and improves the reliability of the anti-thrombus system.

[0192] The anti-thrombus system of the embodiments of the present application inflates or deflates the pressurized air bag of the limb pressure sleeve 10 by the anti-thrombus device host 20, so that the pressurized air bag is cyclically pressed against the limb and released, thereby realizing pressurized massage and anti-thrombus. Moreover, the anti-thrombus device host 20 and the limb pressure sleeve 10 are separately arranged, which is beneficial to improve the comfort of wearing the limb pressure sleeve 10 by the user, and thereby is beneficial to improve the pressurized massage effect.
