The bag 41 of disposable humidication bag adopts medical grade sheet film material to make the bag shaped structure of sealing through the fusion pressing.The aseptic humidification fluid of filling in the bag, the height of liquid level is approximately 2/3 of bag 41 height.Liquid level is the oxygen humidification space with top, and bag 41 is connected to air inlet pipeline and outlet pipe.
Air inlet pipeline is made up of humidication bag suction nozzle, humidication bag air inlet pipe and air inlet micropore 427, and the humidication bag suction nozzle is the link of humidication bag and oxygen pipeline, cooperates with suction nozzle clamping seat 51 by the pipeline Automatic Link Establishment.The front end of humidication bag suction nozzle is provided with clamping annular groove 52, the humidication bag suction nozzle comprises suction nozzle body 422 and suction nozzle pedestal 421, the fusion pressing has puncture to open shutoff sheet 423 in the suction nozzle body 422, leave cavity after the assembling between suction nozzle body 422 and the suction nozzle pedestal 421, be provided with filter membrane 424 in the cavity.The humidication bag air inlet pipe is the groove of falling T-shape shape structure, fusion is pressed together on a rear flank face of bag 41, form the air inlet pipeline passage of sealing, vertical pipeline is oxygen channel, bag 41 sides of the lateral duct correspondence that connects down offer some micropores, and micropore is offered the position near below the bag 41 bottom liquid levels.
Outlet pipe is to be assemblied by humidication bag escape pipe 434, humidication bag outlet nozzle 431, air pressure opened shutoff sheet 432 and disposable Oxygen tube, be installed in the bag 41, the humidication bag outlet nozzle 431 gentle unpacking jams 432 that press off are positioned at more than the top liquid level of bag 41, as shown in figure 11, the horizontal mouth of pipe of humidication bag outlet nozzle 431 is wedge angle lip shape hatch frame, the horizontal mouth of pipe and the mouth of pipe back fusion respectively are pressed together on the inwall of bag 41 cephacorias and bag 41 caudacorias, play the sealing function of outlet pipe.
Owing to adopted the sealing liquid structure of the inlet, outlet pipeline of humidifying bag 41, in the storage and transport process of humidication bag, the humidification fluid in the bag 41 is sealed in the bag 41, has avoided leakage and the pollution of humidification fluid.The top of bag 41 is provided with the dosing plug, is used for the humidification fluid dosing when clinical.
After the humidication bag suction nozzle inserts suction nozzle clamping seat 51, closed lid 32, the location ball 511 of suction nozzle clamping seat 51 is locked the humidication bag suction nozzle, pipeline is from being dynamically connected, the metal blade 538 of puncture connection-peg 23 front ends punctures puncture and opens shutoff sheet 423, oxygen filters by 424 pairs of oxygen of filter membrane, oxygen after the filtration enters humidification fluid by humidication bag air inlet transverse tube 426 from some micropores, gas forms some small bubbles, because bubble is small, the dynamics of explosion is little when overflowing the humidification fluid surface when bubbles of oxygen, solved on the one hand the noise that produces when air pocket overflows liquid level, on the other hand because the increasing of bubble particles, corresponding oxygen contains liquid particle also can be increased, be added to the content liquid in the oxygen molecule, improved clinical result of use.Because the front-back fusion of air pressure opened shutoff sheet 432 is pressed together on bag 41 inwalls, the front and back bulk of the thickness at fusion pressing position after less than humidication bag box closure, along with entering of oxygen in the bag 41, oxygen after humidifying increases bag 41 internal pressures, bag 41 expands gradually, at little pressure state bag 41 and the sharp corner of air pressure opened shutoff sheet 432 from lip shape opening are begun to tear, bag 41 be gradually a process separating of air pressure opened shutoff sheet 432, such structural design is to separate the impact that the humidication bag box is caused for fear of the sheet 432 of air pressure opened shutoff under high pressure suddenly with bag 41.After air pressure opened shutoff sheet 432 separated, the oxygen after the humidifying entered disposable oxygen uptake pipeline 433 by air pressure opened shutoff sheet 432, enters into patient's nasal cavity.
Embodiment two:
Present embodiment and embodiment one fundamental form are together, difference is: as shown in figure 13, the described self-starting plugging device of giving vent to anger comprises the shutoff ball 435 that is arranged on described humidication bag escape pipe 434 inlet ends, described humidication bag escape pipe 434 has elasticity, described shutoff ball 435 and described humidication bag escape pipe 434 interference fit.
Corresponding with it, the integrated form sterilized humidifying oxygen inhalation apparatus corresponding with present embodiment also has corresponding variation, as shown in figure 14, the inboard of described lid is fixed with the driving lever 436 that described shutoff ball 435 can be extruded in the described humidication bag escape pipe 434, and the end of described driving lever 436 is smooth circular-arc.
After being placed into disposable humidication bag in the humidication bag box, as shown in figure 16, in the process of closed lid 32, driving lever 436 rotates with lid 36, the end of the humidication bag escape pipe 434 in the disposable humidication bag is directly pushed in the circular arc end of driving lever 436, as shown in figure 15, shutoff ball 435 is extruded from the end of humidication bag escape pipe 434, shutoff ball 435 drops in the humidication bag, finishes the automatic unpacking of humidication bag escape pipe 434; After the complete closure of lid, driving lever 436 rotates the compressing that breaks away from humidication bag, and humidication bag returns to initial condition.
In order to protect humidication bag; as shown in figure 17; humidication bag squeezing roller 437 can be set at the free end of described driving lever 436; rely on the directly end of the described humidication bag escape pipe 434 of extruding of humidication bag squeezing roller 437; shutoff ball 435 is extruded from the end of humidication bag escape pipe 434, and this mode can not destroyed the sealing of humidication bag.
The humidication bag escape pipe is to be fixedly installed on the bag inner surface of humidication bag, in order to prevent in the process of extruding humidication bag escape pipe, the bag inner surface of humidication bag escape pipe from humidication bag pulled off, bag inner surface at humidication bag escape pipe and humidication bag directly is provided with escape pipe fixed support 7, as Figure 14 and shown in Figure 15, described escape pipe fixed support 7 is near the inlet end of described humidication bag escape pipe.
Description of the present utility model provides for example with for the purpose of describing, and is not exhaustively or with this utility model to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment that have various modifications that this utility model design is suitable for special-purpose.
