Described dry bag 4 is built with quicklime or silica-gel desiccant.Described check valve 14 needs to exceed the just conducting of certain pressure value, even if exocoel leaks gas like this, inner chamber also can not decompression and coming off.The position of described gum elastic bowl inwall between adjacent two male part forms the reinforcement 22 longitudinally arranged, makes other position of gum elastic bowl can not produce excessive deformation like this in pressing male part.Described rack periphery forms a circle locating dowel 32, and locating dowel is close on the inwall of gum elastic bowl, thus is well fixed by rack.
During use, a male part on pressing gum elastic bowl sidewall, the tank mouth of suction cup is aimed at and unclamps the pressing to male part after being adjacent to acupuncture point on a patient body, male part produces the trend restPosed, thus make produce negative pressure in gum elastic bowl and inner chamber and suck on skin, because the air pressure of exocoel is higher than inner chamber, the partial air of outer intracavity enters in inner chamber through check valve, then outer intracavity also produces negative pressure and sucks on skin.The cup time is generally 15-20 minute, in the process, can press gum elastic bowl by phased manner and the air pressure in inner chamber is changed, thus stimulate acupuncture point, enhance therapeutic effect; The change of air pressure makes the skin near suction cup in addition, muscle produces motion, plays the effect of massage simultaneously.
By the evagination wall of the multiple different-thickness of molding on described gum elastic bowl, when the same amplitude of such pressing different evagination wall, the negative pressure produced due to the restoring force effect of evagination wall is different, so just can obtain different vacuum magnitude easily, be suitable for the acupuncture point that cup is different.Described exocoel, between inner chamber and body skin, form two independently cavitys, can inhale securely on skin, be not easy to come off.In the process of cup, available hands extrudes gum elastic bowl by phased manner the air pressure in inner chamber is changed in addition, play the effect of stimulating acupoint, blood circulation promoting, strengthen therapeutic effect, and outer part sucks all the time in this process, difficult drop-off on skin.In many patient bodies, dampness weight, there will be steam in tank during cup, by placing dry bag with the steam of discharging in the human body that absorbs water in time in suction cup, can reduce cup position pore and amplifying and high humidity and cause the risk that bacterial virus is invaded from skin.
embodiment 2
According to Fig. 1, Fig. 4, the suction cup of a kind of slip-off preventing described in the present embodiment, includes an integrated lucite body 1 and is socketed in of body one end in order to produce the gum elastic bowl 2 of negative pressure; Described lucite body includes a circular outer tube body 11 and an interior tube body 12 coaxially arranged with outer tube body, is connected between one end of described interior tube body, outer tube body by a ring-shaped connecting wall 15; Form an annular exocoel 102 between described outer tube body and interior tube body, in described interior tube body inner circumferential and gum elastic bowl, form an inner chamber 101; Described interior tube body is provided with one by the check valve 14 of exocoel to inner chamber one-way conduction; One end of lateral wall next-door neighbour's ring-shaped connecting wall of described outer tube body forms an outer flange collar 13, and described gum elastic bowl forms the recessed circle coordinating snapping with outer flange collar near the position of port; Described gum elastic bowl side wall surface forms the individual outwardly evagination wall 21 of 4-5; The thickness of described evagination wall is all less than the thickness of other position of gum elastic bowl, and the gradual change successively of the thickness of each evagination wall; Described ring-shaped connecting wall is placed with a rack 3, rack forms a tank 31 towards the side of gum elastic bowl, rack is at least positioned at tank position and evenly forms through hole 33, in described tank, be placed with the dry bag 4 absorbing moisture.
Described dry bag 4 is built with quicklime or silica-gel desiccant.Described check valve 14 needs to exceed the just conducting of certain pressure value, even if exocoel leaks gas like this, inner chamber also can not decompression and coming off.The position of described gum elastic bowl inwall between adjacent two male part forms the reinforcement 22 longitudinally arranged, makes other position of gum elastic bowl can not produce excessive deformation like this in pressing male part.Described rack periphery forms a circle locating dowel 32, and locating dowel is close on the inwall of gum elastic bowl, thus is well fixed by rack.
The sidewall of described gum elastic bowl is connected with a gas-tpe fitting 23, and gas-tpe fitting is connected with a vacuum pump by connection tube; Described gas-tpe fitting sidewall is connected with an air valve 24; Described vacuum pump is interrupted to be opened.After suction cup sucks on skin, by being interrupted unlatching vacuum pump, negative pressure in suction cup inner chamber is strengthened, outside air enters inner chamber from air valve simultaneously, makes the air pressure in inner chamber constantly change like this, play the effect of stimulating acupoint, blood circulation promoting, strengthen therapeutic effect.Described vacuum pump connects multiple suction cup by connection tube, and vacuum pump controls it by a controller and automatically carries out discontinuity work.
During use, one or more male part on pressing gum elastic bowl sidewall, the tank mouth of suction cup is aimed at and unclamps the pressing to male part after being adjacent to acupuncture point on a patient body, male part produces the trend restPosed, thus make produce negative pressure in gum elastic bowl and inner chamber and suck on skin, because the air pressure of exocoel is higher than inner chamber, the partial air of outer intracavity enters in inner chamber through check valve, then outer intracavity also produces negative pressure and sucks on skin.The cup time is generally 15-20 minute; vacuum pump is interrupted to carry out bleeding and makes in inner chamber air pressure reduce in this process, and outside air enters inner chamber from air valve simultaneously, and the air pressure between vacuum pump down period in inner chamber raises gradually; reduce gradually again after vacuum pump starts again, constantly circulate.In inner chamber, the change of air pressure makes skin near suction cup, muscle produce motion, plays the effect of massage simultaneously.
In addition, in order to ensure suction cup difficult drop-off, described air valve two ends conducting needs a draught head, like this when inner chamber air pressure is raised to the highest still lower than atmospheric pressure, can ensure to make exocoel to produce gas leakage suction cup and also not come off.
