As shown in Figure 5, upper strata air bag 14 or lower floor's air bag 26 of lower limb cover 10 are made up of roof 54 and diapire 56.In the time using lower limb cover, diapire 56 is near patient's shank.Roof 54 and diapire 56 have inner face 58 separately, and 58 ' and outside 60,60 ', correspondingly locate to combine with junction 68,70,33,35,36 etc.Define the profile (only have junction 64 visible in Fig. 5) of air bag.Inner face 58,58 ' is made up of polyethylene, as metal polyethylene DOW Chemical material, the material that a kind of relative cost is lower.Although this material is not very hard, its solderability and sealing are all fine.But patent utility model person has tested and confirmed that 100 to 150 microns of thin polythene materials have enough hot strengths and persistence, guarantee the limit cycle number of inflation venting.For the date before and after corrective surgery, this periodicity normally 30000.This quantity may be relatively less, and approximately have 250 in one or two step of therapeutic compression, thereby can use thinner polythene material.If air bag can not be completely around limbs, and just around 2/3rds or limbs still less; The intensity of airbag wall may further reduce so.Here it is, and why this material is applicable to making inflating pressure lower limb cover very much, for preventing the formation of extremity deep venous thrombosis.Outside 60 and 60 ' is made up of porous material (as weaving face fabric).Best material is non-woven fabrics weaving face fabric, as polypropylene or polyester textile.
As shown in Figure 6, the combination of composition thin plate is by a kind of special method.Two polyethylene boards 58 and 58 ' are welded to each other in weld zone 66, by as the method for radio frequency heating.Meanwhile, the poly melt portions 72 of weld zone 66 is permeated outside 60 and 60 ' the pore of porous and is set in weld zone 66.In addition, this melt portions makes outside 60, and 60' and polyethylene board 58 and 58 ' are separated from each other.It should be noted that porous material does not need to be welded to polyethylene layer.Patented invention person has been found that the combination of composition thin plate is may be very reliable and the equal number in above-mentioned inflation venting cycle can be provided for required robustness.
As shown in Figure 7, the lower limb cover 10 of compression therapy can be by strengthening internal layer thin plate 158 version and that structure is more complicated, and 158' makes.For example, internal layer thin plate 158 or 158' comprise non-woven fabrics or the nylon layer of strengthening version, are clipped between two layers of polyethylene 162 and 164, thereby form complete thin plate (as lamination).This material is for packaging for foodstuff industry, and cost of manufacture is relatively low.In this case, the integral thickness of internal layer thin plate may also not have pure polyethylene inner thin plate hight.
Shown in Fig. 8 and Fig. 9 is the disposable inflating pressure lower limb cover 110 according to another example system.Lower limb cover 110 comprises top section 112 and underclad portion 124.Wherein, top section 112 contains upper strata air bag 114, as pressurization patient shank 116; Also comprise upper strata fixed tab 118 and 120, form the left and right sides of air bag 114.Underclad portion 124 contains lower floor's air bag 126, as pressurization patient sole 128, also comprises lower floor's fixed tab 138 and 140.The air inlet (nozzle) 141 of upper strata air bag 114 and lower floor's air bag 126 utilizes flexible pipe to be fixedly connected in air bag.Form thus aerating device, as the prelum that contains partial pressure valve (without diagram).
According to Fig. 9 and Figure 10, upper strata air bag 114 or lower floor's air bag 126 of inflating pressure lower limb cover 110 are made up of roof 154 and diapire 156.While using lower limb cover, diapire 156 is configured to contact patient's shank.Roof 154 and diapire 156 form internal layer thin plate 158,158', and outer sheet metal 160,160', and (only have 164 and 164' joint be presented at Figure 10) mutually links together at multiple joints.Internal layer thin plate 158,158' are encapsulant (as polyethylene), further enhanced polyethylene fiber.Outer sheet metal 160,160' is porous material (as weaving face fabric), best material is non-woven fabrics weaving face fabric, as polypropylene or polyester textile.
Inflating pressure lower limb cover 110 is also included in multiple pores 200 of internal layer thin plate 158,158' formation.The Shi Fei inflatable region, region of its formation, namely this patent lower limb overlaps all parts except air bag 114 and 126.Wherein, on-inflatable district can form the region of contiguous solder joint, the region (Figure 10) between solder joint and fixed form (as fin 18 and 20 etc.).Outer sheet metal 160,160' does not have corresponding pore 200.The pore 200 that such situation can key diagram 9 dots is for illustrating that they are in outer plate 160, the position below 160'.
As shown in figure 10, air bag 114 and 126 has two joints 164 and 164' between it at least partly.Both are separated by because have isolation area between whole thickness, the place that pore 200 forms at internal layer thin plate 158,158' just.
In practical operation, the aeration of air bag makes the on-inflatable district of lower limb cover separate from patient body, thereby causes the air outside lower limb cover to flow into (shown in Fig. 9 arrow) from the pore of outer sheet metal and the pore of internal layer thin plate.In other words,, when airbag aeration, between patient body and lower limb cover (except air bag), forming vacuum layer.Therefore ambient air can pass through the pore of outer sheet metal and these regions of pneumatic inflow of internal layer thin plate.Also therefore,, in the stage of inflation venting, near instrument patient skin can allowing air flow and evaporation of perspiration.
In order there to be better spacing, pore can be positioned on joint and approach most the place of air bag.
