Description
Technical field
The present invention relates to a kind of air pressure regulator, but particularly relate to the air pressure regulator that a kind of multistage is regulated the breathing resuscitator of air pressure.
Background technology
As shown in Figure 1, 2, the breathing resuscitator 1 that uses during general first aid include a breathing ball 11 that is hollow form, one with breathe gas transmission joint that ball 11 1 ends are connected 12, one with breathe turnover gas bent sub 13, that ball 11 another end opposite are connected and be located at face shield 14, on the turnover gas bent sub 13 and be located on the turnover gas bent sub 13 and valving 15, an oxygen bag that is connected with gas transmission joint 12 16, of vicinity breathing ball 11 are located at the appendix 17 on the gas transmission joint 12.Pass in and out on the gas bent sub 13 and be provided with on one side and take over 131.And valving 15 has a valve block 151, in order to sealing other 131 the capping 152 of taking over, and a spring 153 that is positioned between valve block 151 and capping 152 inner surfacies, in the capping 152 and offer a venthole 154.
When sufferer is done artificial first aid respirator, face shield 14 covers can be placed the place, nose and mouth of user, and appendix 17 other ends are connected to the place, gas outlet of an oxygen cylinder (figure does not show), so oxygen will be by in the appendix 17 input gas transmission joints 12, breathe ball 11 places and be provided with a baffle plate (figure does not show) in contiguous in the appendix 17, make a part of oxygen flow into and breathe in the ball 11, major part is input oxygen bag 16 under the baffle plate guiding then, when the amount of oxygen in the oxygen bag 16 reaches a certain amount of, can push oxygen bag 16, make in the oxygen bag 16 oxygen output and through breathing ball 11, turnover gas bent sub 13, face shield 14 and smoking for sufferer.
In the process of extruding oxygen bag 16 output oxygen, the air pressure in breathing ball 11 surpasses for example 30～45cmH
2During O (centimetre water column), gas partly will borrow gas pressure power pushing tow valve block 151 to open by other adapter 131 as shown in Figure 3, and then be discharged by the venthole in the capping 152 154.Air pressure in breathing ball 11 recovers just often, and valve block 151 can discharge elastic-restoring forces and air pressure thrusting action power reduce down at spring 153 immediately, resets as shown in Figure 2 and seal other adapter 131, so reaches the effect of adjusting air pressure.
Yet only have single venthole 154 in the capping 152, cause via the gas output of venthole 154 outputs and can't do the trace adjusting, the comfort of user is still desirable to the greatest extent.

The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Consulting Fig. 4, is a preferred embodiment of the air pressure regulator 3 of breathing resuscitator 2 of the present invention, and wherein breathing resuscitator 2 is structure in the past, is not for target of the present invention place, does not repeat them here.What specify is, air pressure regulator 3 of the present invention is on the turnover gas bent sub 21 (be positioned at and breathe ball 22 and 23 of face shields) that is arranged at breathing resuscitator 2, and passes in and out on the gas bent sub 21 and be provided with a venthole 211.Described air pressure regulator 3 includes a body 31, piston body 32, a flexible member 33, and a lid 34.
Cooperate shown in Figure 5, body 31 has a median wall 311, and a surrounding wall 312 that is connected in 2 of median wall 311 and breathing resuscitators, then be provided with a steam vent 313 on the median wall 311 and be positioned at the locating hole 314 of central position, and surrounding wall 312 outer surfaces of body 31 convex with ring wall 315.In addition, median wall 311 is with surrounding wall 312 and described breathing resuscitator 2 outside wall surface and define an improving inspiration by invigorating kidney-QI space 316 jointly, and the improving inspiration by invigorating kidney-QI space 316 in the body 31 just can see through venthole 211 and be connected with breathing resuscitator 2 whereby.
Still as shown in Figure 5, piston body 32 has a dish seat 321, and dish seat 321 end faces are concaved with a storage tank 322, and dish seat 321 bottom surfaces then convex with a seat leg 323.The seat leg 323 of piston body 32 is to be inserted in the aforementioned venthole 211, and aforementioned flexible member 33 1 ends are to stretch in the storage tank 322 that places piston body 32, and the other end then is to be resisted against body 31 median walls 311 inner surfacies.When normality, flexible member 33 is to be extended configuration and the aforementioned venthole 211 of dish seat 321 sealings of energy pushing tow piston body 32.
As shown in Figure 5, has a roof 341 as for 34 of lids, and one with roof 341 around the perimeter wall 342 that is connected, roof 341 is provided with most the different adjustment holes 343 (as shown in Figure 6) of pore size, described adjustment hole 343 is to be camber line along lid 34 peripheries to be spaced.Roof 341 inner surfacies also convex with a clamping piece 344, and clamping piece 344 has a shaft 345, and an abutting end 346 that is formed at described shaft 345 ends.Lid 34 is to utilize clamping piece 344 to run through aforementioned locating hole 314, and median wall 311 inboards of borrowing abutting end 346 to be placed in body 31, and constitutes rotatable pivot joint relation with body 31.
As Fig. 5, shown in 7, in the process of breathing resuscitator 2 output gases, air pressure in breathing ball 22 (see figure 4)s surpasses default value for example 25 or during 30cmH2O (centimetre water column), gas partly will and be borrowed 32 displacements of gas pressure power pushing tow piston body by venthole 211, make the dish seat 321 of piston body 32 away from the position of venthole 211, flexible member 33 forms compressive states at this moment, gas just can via venthole 211 input improving inspiration by invigorating kidney-QI spaces 316 and and then discharge by the steam vent 313 of body 31 and with the adjustment hole 343 of described steam vent 313 corresponding lids 34, simultaneously can be according to different users's vital capacity difference, rotation lid 34, as long as make adjustment hole 343 suitable on steam vent 313 and the lid 34 on the body 31 corresponding, can reach multisection type and regulate the effect of air pressure, so the comfortableness that can provide user to use really.
As above-mentioned, the air pressure regulator 3 of breathing resuscitator 2 of the present invention designs by above-mentioned structure, provide the different users required, rotation lid 34, make that the adjustment hole of suitable pore size is corresponding with the steam vent 313 on the body 31, can remain on the optimum gas pressure condition in the breathing resuscitator 2, allow the user can happier ground and breathe comfily, therefore, can reach the purpose of the invention described above really.
