Detailed description of the invention

Hereinafter, by for the use on patient legs, embodiments of the invention are described.But, should be appreciated that the present invention is also applicable to any limbs, such as arm, foot, a part of lower limb, arm or foot, and can simultaneously for plural limbs.

In FIG, shown patient carries out her routine work dress massage sleeve 1 of the present invention on its lower limb while.In FIG, the trouser legs of patient are cut off to expose sleeve.But in fact, sleeve keeps hiding and not seen, and due to feature of the present invention, even if at chamber by aeration period off and on, sleeve is not noticeable yet.Sleeve 1 has the inner surface and outer surface that are made up of durable flexible material, and is divided into multiple chamber 2 along its length, and each chamber is by being connected to control unit 3 by the unified independent pipe being labeled as 4 in Fig. 1.A part for sleeve, such as, be positioned at those parts around knee and ankle joint 5, can be not inflatable elastomeric material.

From Fig. 2 and Fig. 3, each chamber has fluid provider 6, and ingate 6 is connected with the flexible pipe 4 from control unit 3.Control unit 3 comprises compressor, the more than one chamber selected by this compressor can be pumped in sleeve by ambient air and via flexible pipe 4.Control unit 3 allows the time-space rule of inflation and venting to selected chamber, such as, for generation of sleeve peristaltic contraction thus force the rule of the direction of flow limbs near-end in limbs, or for strengthening the rule of the venous blood flowing in limbs.As shown in Figure 2 and Figure 3, the seriality of wriggling is strengthened by making the compartment of adjacent chamber in massage sleeve intermesh.

According to the present invention, chamber is subdivided into the compartment 7 of multiple longitudinal extension.Such as by the border along each compartment the massage inner shell of sleeve and shell be welded together and form each compartment.Compartment in given chamber due to the eyelet 8 in the seam between adjacent compartments but be communicated with, make all compartments in chamber be inflated in fact simultaneously and exit.Each compartment presents in fact its axis being parallel in the cylindrical shape of the axis of limbs when being inflated.

Fig. 4 A shows the cross section of the chamber of venting, and Fig. 4 B shows the same cross section after inflation.Chamber is divided into such as ten identical compartments, obviously, can adopt the compartment of any other number.If N is the compartment number in given chamber, and r is the radius of the compartment of inflation, and so as can be seen from Fig. 4 B, the length through the periphery 10 at charging compartment center is 2Nr, but the girth 9' of the chamber of venting is N π r.Therefore, the part of the periphery after inflation is reduced to:

$\frac{\mathrm{N\πr}-2\mathrm{Nr}}{\mathrm{\πNr}}=1-\frac{2}{\mathrm{\π}}=0.36---\left(1\right)$

The inner rim 9 of chamber of inflation " length will be less than 2Nr, make the part reduction of the inner rim after inflating be greater than 0.36.

Select N and r, the former periphery of the limb part that π Nr (periphery of the chamber of venting) is held corresponding to intracavity in chamber.The part of the periphery of the chamber after inflation reduces the contraction that (0.36) causes chamber, and independently pressure is applied to limbs according to above-mentioned equation (1) with N and r by this contraction.Therefore, fully large by being chosen to by N, and be chosen to by r correspondingly little, can obtain sleeve, the neighboring making it inflate is not more than the former neighboring of limbs substantially.The equipment of this and prior art described above is formed and contrasts, and in order to realize the pressure identical with the pressurization that the present invention produces, must have the periphery of the former periphery large 36% than limbs.

Now, assuming that L is the length of chamber, and be contained in the former periphery C=N π r of the limbs in chamber, by Fig. 4 easy understand, the original volume being contained in the limbs of the chamber of venting is: $V_D=\mathrm{\π}{\left(\frac{C}{2\mathrm{\π}}\right)}^{2}L.$

The final volume being contained in the limbs in the chamber of inflation is less than

The limbs volume of chamber chambers contain is made about to reduce 59% to chamber inflation.This represents the fluid volume extruded from limbs, or represents the achievement completed by sleeve.This is by being inflated to cumulative volume by the compartment of chamber $V_T={\mathrm{N\πr}}^{2}L=\mathrm{N\π}{\left(\frac{C}{\mathrm{N\π}}\right)}^{2}L=\frac{C^{2}L}{\mathrm{N\π}}$ Realize.

In contrast to this, in order to be obtained the reduction of identical limbs volume by the method for prior art, need chamber to be inflated to final volume $V_F=\mathrm{\π}\{{\left(\frac{1.36C}{2\mathrm{\π}}\right)}^2-{\left(\frac{0.64C}{2\mathrm{\π}}\right)}^2\}L=\frac{C^{2}L}{2.8\mathrm{\π}}.$

Therefore, when in chamber of the present invention, the number of compartment is at least 3, the volume that chamber must be inflated is less than the volume of the equipment of prior art.In addition, fully large by N is chosen to, can by chamber being inflated to the reduction that arbitrarily small cumulative volume realizes 59% of limbs volume.Such as, as N=30, the cumulative volume of inflating cells is less than 1/10th of prior art filling apparatus gas chamber volume.This compressor making it possible to use the compressor that uses than the sleeve of prior art much smaller, thus allow patient can walk about when thing is treated by the present invention.

Note, may be used for the bone of the fracture in fixed limb according to the sleeve 1 in such as Fig. 1 and Fig. 2 of the present invention or the sleeve of more small sleeve and so on that only covers a part of limbs.
