Description
Technical field
This utility model is about a kind of prosthetic socket vac sorb joint having lock function, for regulating the deformed limb of user
Being used with artifucial limb closed intensity, its feature is a key pressing releasing to hold a vacuum state and unlock artifucial limb liner simultaneously
Set stop pin, more allows artifucial limb simplify its tedious steps when dismounting.
Background technology
Generally artifucial limb user is when assembling, after its deformed limb artifucial limb neck bush through cladding made of soft, and correspondingly-sized
Quite size hold cylinder, coordinate auxiliary device by the additional air of deformed limb Yu prosthetic socket, form maximum by extraction action
Change vacuum density；But, general existing textural, the situation causing artifucial limb to depart from for avoiding gas check damaged or to lose efficacy is sent out
Raw, its regulation vacuum structure can coordinate a latch-up structure, though two structures will not influence each other in actual use, but in use
For person, there is loaded down with trivial details inconvenience during removal artifucial limb in fact；
Such as United States Patent (USP) US627787, this case feature is that locked component passes through the corresponding locking of a single direction ratchet
Pin, utilizes button spring to coordinate centration axis, promotes this single direction ratchet to be produced rotation or fixing, allows this artifucial limb neck bush lock
Pin can enter and exit this locked component.Though this locked component is provided simultaneously with one-way exhaust valve, but there are no and can external vacuum take out
Inhale the design of device, be also not provided with prosthetic socket absorption affinity and release mechanism；This locked component can be had a clear understanding of and only have linking functions,
Rather than be used as prosthetic socket vac sorb；
And United States Patent (USP) US6334876, this case feature be to be placed in locking mechanism hold cylinder in and be combined into an airtight sky
Between, when unlocking this locking mechanism, extraneous air can be simultaneously introduced and release prosthetic socket absorption affinity, said structure know, its
Design has the advantage simplifying spare part quantity.But this case is not provided with one-way exhaust valve, when non-being unlocked by pressing device, then cannot
Persistently discharge and hold the air in cylinder, thus result in and hold an absorption affinity when being unable to maintain that user walking；Furthermore, outside this case there is no
Connect the design of vacuum suction apparatus, be not intended as prosthetic socket vac sorb and be used.
And United States Patent (USP) US8211187, this case feature is that central guiding valve has passage, can be helped by external vacuum
Pu cooperation is internally formed vacuum or is introduced extraneous air releasing vacuum state.Though this case is also provided with one and is placed in the lock holding in cylinder
Determine mechanism, but when unlocking this locking mechanism, and the suction in prosthetic socket, therefore user artifucial limb to be taken off cannot be released simultaneously
Time, first have to push guiding valve open, then to pin the tripper on locking mechanism again, just released the link of artifucial limb with solid
Fixed.This case, for actual face, increases user really in operational inconvenience；Therefore, in place of its operability still has improvement.
And patent WO2015002955A1 a case, wherein disclose set gas passage in the feature of structure is stop pin,
Can allow and hold cylinder and be internally formed vacuum state by external vacuum pumps, add strong security further through locking device.But this case is not provided with list
To air bleeding valve, when external vacuum pumps lost efficacy, air will enter and hold cylinder destruction vacuum state；Furthermore, this case does not design
Unlocking the mechanism of vacuum state, it needs to improve in place of still having inconvenience.
In sum, various about stop pin and vacuum conditions structure, it not that structure is the most complicated, it is simply that for functional separation
The composition of design, knows after research in reality application by aforementioned structure, it still suffers from shortcoming to be improved.
Utility model content
Because existing structure, on using, there are complicated and unhandy situation, therefore, mesh of the present utility model
Be how by existing vacuum conditions with link fixed structure and unite whole combination, be and of the present utility model mainly solve
Technical problem.

Cock body 35 sequentially links composition, constitutes a kind of Non-return air valve, is only restricted in fluid one-way flow, and this penetrating via 112 separately sets
Having one second suction vacuum passage 116 to be connected to this spigot joint 34, the other end of penetrating via 112 is then provided with a locked component
2, this locked component 2 is sequentially linked by pressing piece 21, sealing ring 22, limited block 23, spring 24 and forms, and in this limit
Position block 23 is longitudinally provided with an obturator hernia 231.
Referring to as shown in Fig. 7 Fig. 8 A, its obturator hernia 231, and can be just with the contact surface 232 of the inclination of previous embodiment
The taper surface 132 of corresponding stop pin 13, when stop pin 13 is fitted and fixed with in this obturator hernia 231, this penetrating via 112 is in tune
The position of joint needle 31 one end, is locked the pin 13 space between groove 131, is formed with chamber 114, and this chamber 114 is joined
Closing the second suction vacuum passage 116 being linked with penetrating via 112, the vacuum pumps utilizing spigot joint 34 to link outside is taken out
Take this chamber 114 and hold cylinder 61 in communication with what upper end linked and hold artifucial limb neck bush 6 air between the two, such as the aerofluxus body in figure
Shown in flowing C 42 so that it is vac sorb intensity is regulated, when to user optimal adaptation state, outside manually closing
Vacuum pumps that portion links and rotate this regulation needle 31 and inhale between vacuum passage 116 to intercept this chamber 114 and second
Connection relationship；And when user dismounting artifucial limb rest time, after pressing this locked component 2, this contact surface 232 will to the left by
Promote, and make the taper surface 132 with this stop pin 13 depart from, now can be by pore 113 by extraneous air, such as the air inlet body in figure
Shown in flowing D 43, hold artifucial limb neck bush 6 inside via this Vacuum solutions except passage 113 flows into, in order to release vacuum originally
State, allows stop pin 13 be taken out.
And above-mentioned locked component 2 is not when pressing, inside configuration relies on spring 24 to push away limited block 23, and limited block 23 and pedestal
The inner plane of 11 has a sealing ring 22, it is possible to prevents air from passing through penetrating via 112 and causes vacuum leak.And locked component 2
During pressing, sealing ring 22 interlocks with limited block 23, makes sealing ring 22 depart from pedestal 11 inner plane and no longer seals, and air can be directly
Chamber 114 is flowed into release vacuum with Vacuum solutions except passage 113 by penetrating via 112.
In above-mentioned two embodiment, the visible tune by position set by cock body 35 and spigot joint 34 in diagram can be coordinated
Whole, changed by be allowed Transfer tectonics；And the purpose of this utility model is to allow vacuum conditions and two kinds of functions of latch locking
Being integrated design, beneficially user is with the most simple and convenient operation, adjusts its comfort level at any time, and central used by connect
