Ask, inventor finally passes through to be wound around or bandage type sealing solves this problem well, because encapsulant is cheap, can
Produced with a large amount of, and the sterilization to encapsulant can be removed from and avoid cross-infection, therefore have extremely with single use
Bright prospect of the application, is limb therapeutic equipment entrance medical market and health care market provides optimal encapsulating method and selects.
Utility model content
The technical problems to be solved in the utility model is, for the disappearance of limbs Sealing Technology and deficiency in prior art,
Propose the clearance sealing structure between a kind of limbs and limb therapeutic or health care facility cavity hatch, solve limbs well close
Envelope, and operation is simple and reliable, with low cost, it is suitable for pushing medical and civilian health care market to.
The utility model is that the technical scheme solving above-mentioned technical problem proposition is: a kind of limbs and limb therapeutic or health care
Clearance sealing structure between equipment cavity opening it is characterised in that: have and be suitable for being wound in limb therapeutic equipment cavity opening
With the flexible sealing material on limbs, the one ends wound of described flexible sealing material at limb therapeutic equipment cavity opening, separately
On limbs, the gap between limb therapeutic equipment cavity opening and limbs is sealed one ends wound by described flexible sealing material,
Make cavity hatch and the isolated from atmosphere of limb therapeutic equipment.
The utility model also has the feature that
1st, tighten up on described flexible sealing material with double buckle or bandage.
2nd, the one or both ends being arranged at flexible sealing material with double buckle or bandage are tightened up.
3rd, the cavity hatch of described limb therapeutic equipment and limbs gap location are embedded with the ring liner that can take off.
4th, described flexible sealing material is in banding.
5th, described flexible sealing material be pe, pvdc, latex, nitrile rubber, butyl rubber, neoprene, in pvc one
Kind.
Inventor gropes and adopts winding type flexible seal material (banding), between cavity and limbs through repeatedly practising
Clearance seal, experiment proves that sealing effectiveness is good and easy to operate, is that malleation or negative pressure limb therapeutic equipment are come into market and provided
Simple and reliable technology ensures.
For certain negative pressure (- 20kpa), if after limbs stretch into cavity, between limbs and cavity hatch if gap
Little or area is less, and the flexibility therefore covering area between this gap has the encapsulant of certain elastic force relatively small by bearing
Pressure, less to the pressure of the encapsulant of gap portion, and this pressure is finally to be contacted with limbs surface by cavity flange port
Part encapsulant is shared jointly, if therefore this pressure is little, then the encapsulant to directly contact human body limb such as leg
Pulling force is relatively just less, if this pulling force is less than the maximum static friction force that encapsulant can bear with people's extremity part, by
Encapsulant will be made when negative pressure occurs to fit with limbs increasingly tighter, will not need to increase in the additional bandage of encapsulant again
Plus frictional force, also allow for using comparatively simple convenience and reliability, therefore widely using of limb therapeutic equipment will no longer have barrier
Hinder.
On the contrary, for certain negative pressure, if after limbs stretch into cavity, if gap is larger between limbs and cavity hatch
I.e. area is larger, then the pressure that the encapsulant of this interval area part bears is just big, and it is shared and being contacted with leg laminating
Partial encapsulant pulling force can exceed that the maximum static friction force between limbs and encapsulant comes it would be desirable to add bandage etc.
Increase pressure thus improving frictional force and being unlikely to make encapsulant depart from limbs.
For mitigating, larger pressure is formed to this larger gap portion of material due to pressure reduction, it is to avoid encapsulant ruptures, permissible
Gap location adds the ring liner thing that can conveniently take off in this section, so that gap is reduced, thus reducing the formed pressure of pressure reduction
Effect to encapsulant, protects encapsulant not destroyed by larger pressure and reveal and cisco unity malfunction well.
Experiment shows, the sealing effectiveness under negative pressure or barotropic state of this sealing structure is good and easy to operate, sealing material
Material is cheap, and fit entirely into medical institutions prevents the strict requirements such as cross-infection, is negative pressure or malleation limb therapeutic
Equipment is come into medical market or family health care market and is provided simple and reliable Sealing Technology and ensure.
