Description

Air-bag control device

Technical field

The utility model is related to a kind of pressure adjusting structure, it is espespecially a kind of controlling air bag to change in inflating, maintain the statusquo or The air-bag control device of the different conditions such as exhaust.

Background technology

A kind of air bed has in the streets been peddled, has been used when specializing in patient's long-term bed, prevention skin is produced because of long-term be pressurized Bedsore phenomenon, this air bed carries out the inflation of air bed with an air pump.The air bed is after bedridden patient, based on patient body Type, body weight differ, and the pressure that air bed corresponds to corresponding to partes corporis humani position is all different, therefore air bed is set mostly Count into and formed side by side by a plurality of independent air sac strip, each air sac strip can according to it is different need to adjust inside air pressure to appropriate State.The pressure adjusting structure of existing air bag is arranged in the clad structure of air bed mostly, fairly cumbersome during pressure regulation, need to raise whole Clad structure, and its pressure adjusting structure only has current path or open circuit to wait two kinds of effects, when inside air bag pressure is excessive, or runs into need When wanting CPR first aids, also without decompression function, cause have many limitations and shortcoming when the air bed is Shi Jishiyong.

It is clear that existing air bed pressure adjusting structure is still undesirable perfect, there is improved necessity in fact.Inventor in view of This, spy creates into the utility model to grind, and the phase can borrow proposition of the present utility model, and to improve the shortcoming of prior art, the phase makes air cushion The voltage regulation function of bed is able to more improve and preferable, meets actual demand.

Utility model content

There are limitation and shortcoming functionally to improve foregoing air bed pressure adjusting structure, the utility model provides a kind of air bag Control device, its main purpose is to provide a kind of control device, and it is configured between inflator pump and air bag, can be to control air bag Change in the different states such as inflating, maintaining the statusquo or being vented, consequently, it is possible to when intracapsular pressure is not enough, can carry out supplying sky Pressure, when intracapsular pressure is excessive or needs to carry out CPR first aids, can carry out excretion gas, when intracapsular pressure is appropriate or need to move gas During equalizing bed, can block to maintain the statusquo；Whereby, multi-functional practical purpose is reached.

To reach above-mentioned purpose, the specific technological means of the utility model is：The control device mainly includes a shell body With one in body, the interior body is placed in the shell body, and can turn, the shell body is configured between inflator pump and air bag.

Embodiment

The now careful just structure composition of air-bag control device of the present utility model and the effect that can be generated, coordinate accompanying drawing, act One preferred embodiment of the present utility model describes in detail as follows：

Head is referred to shown in Fig. 1, Fig. 2, and the air-bag control device of the present utility model mainly includes in a shell body 1 and one Body 2, the interior body 2 is placed in the shell body 1, and energy turn, and the shell body 1 is configured between inflator pump and air bag (in figure Do not show).The shell body 1 is in long tubular, and its internal end face is sequentially to be set on open hollow space 10, the shell body 1 There are one first body 11, one second body 12 and an exhaust outlet 13, first body 11, the second body 12 are located at exhaust outlet 13 On same axial line.The interior body 2 is in that one first opening 21 and one second is sequentially equipped with long cylinder hollow form, the interior body 2 Opening 22, and the opening 22 of the first opening 21 and second is on same axial line, and at another corresponding surface of the interior body 2 One the 3rd opening 23 and one the 4th opening 24 are also equipped with, and the 3rd opening 23 and the 4th opening 24 are located at same axial line On, wherein, second opening 22 is located on same profile with the 3rd opening 23, and second opening 22 and the 3rd opening 23 In interpenetrating relationship；After interior 2 groups of the body is placed at the space 10 of shell body 1, first opening 21 and first body 11 For the relation on same profile line；And the opening 23 of the second opening the 22, the 3rd is to be cutd open positioned at same with second body 12 The relation of upper thread；4th opening 24 and the relation that the exhaust outlet 13 is positioned at same profile line.First body 11 be used to Inflator pump is connected, and second body 12 with air bag to be connected.The interior outermost end of body 2 is provided with a knob 20；Also, should First opening 21, second opening the 22, the 3rd opening 23 and the 4th opening 24 at be all each configured with open oil 211,221, 231st, 241, it is airtight to ensure；And the interior body 2 all divides on the side of first opening the 21, second opening 22 and the 4th opening 24 Interval oil sealing 25 is not arranged with, to ensure airtight effect.Also, the interior body 2 is inserted behind the space 10, the interior outer end of body 2 A capping 14 is provided with edge.

When the utility model will perform inflation procedure, that is, need air by inflator pump enter air bag when, rotate the knob 20, such as Fig. 3, make the first opening 21 and overlapping recline of the first body 11 and connect, and second be open it is 22 overlapping with the second body 12 Recline and connect, now, air is entered in the first body 11 by inflator pump, flow through the first opening 21 and enter inside interior body 2, then Passed by second opening 22, exited into through the second body 12 in air bag, that is, complete the inflation operation.

When the utility model, which will be performed, maintains the statusquo program, that is, the first body 11 will be closed with the second body 12 Block；Rotate after the knob 20, such as Fig. 4, make the opening 23 of the 21, second opening of the first opening the 22, the 3rd and the 4th opening 24 Connected to horizontal level, and all without with the first body 11, the second body 12 or exhaust outlet 13, now the first body 11 and second Body 12 all blocks state in closing, that is, completes the setting maintained the statusquo.

When the utility model, which will be performed, lets out vent sequence, that is, air can not be entered in air bag, and air bag by inflator pump Air exhaust outlet 13 need to be transferred to by the second body 12 and release, rotate the knob 20, Fig. 5 please be coordinate, make the first opening 21 Away from first body 11, first body 11 is presented closing and blocks state, and the 3rd opening 23 is connected with the second body 12, And the 4th opening 24 connected with the exhaust outlet 13；Now, air is entered in the second body 12 by air bag, flows through the 3rd opening 23 Passed into inside interior body 2, then by the 4th opening 24, outwards lose heart through exhaust outlet 13, that is, complete this and let out exhaust operation.
