Abstract
The utility model discloses an oxygen pillow, include the gas storage chamber of enclosing by the hard shell body, surround in external soft bullet pads of hard shell and one end stretch into soft bullet bed course the respiratory tube that communicates with the gas outlet in gas storage chamber, be equipped with the admission valve in gas storage chamber on the hard shell body, the admission valve is worn outside soft bullet pad, the gas storage intracavity is provided with rather than air -tight piston, be connected with the piston rod that stretches out outside soft bullet pad on the piston. Through piston rod promotion piston reciprocating motion, can, gas storage intracavity tolerance increase the oxygen flow when constantly reducing, and that oxygen keeps the flow of relative temperature to supply with patient.
Description
Technical field
This utility model relates to a kind of oxygen pillow, and it comprises air storing cavity and air tube.
Background technology
At present on emergency tender, go out to give emergency treatment to a patient or critical patient transfers from one hospital to another, need to patient's oxygen supply when transporting, generally adopt oxygen pillow or oxygen bag, oxygen pillow is made up of soft bag, stores oxygen in bag, simple to operate, easy to carry.But also Shortcomings part: the oxygen in oxygen pillow mainly relies on head gravity or manual compression are forced out oxygen pillow and enter patient through air tube, along with the oxygen content in oxygen pillow is fewer and feweri, the bag of oxygen pillow is more and more flat, oxygen in oxygen pillow is more and more not easily forced out, and flow is more and more less, patients ' demand cannot be ensured.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of oxygen pillow, can ensure that oxygen in oxygen pillow is when content is less, still can keep certain flow.
Oxygen pillow of the present utility model, comprise the air storing cavity surrounded by hard shell, the soft bullet pad be enclosed in outside hard shell stretches into one end the air tube be communicated with the gas outlet of air storing cavity in soft bullet bed course, described hard shell is provided with the intake valve of air storing cavity, described intake valve is worn to outside soft bullet pad, be provided with the piston airtight with it in described air storing cavity, described piston be connected with the piston rod extend out to outside soft bullet pad.
Further, be provided with spring between described piston end surface and hard shell, when to gas storage interacvity air-filling, described spring is constantly compressed.
Further, the side of described soft bullet pad relative harder housing is provided with groove, and be provided with oxygen humidification bottle in described groove, the outlet of described oxygen humidification bottle is connected with air tube, and the entrance of described oxygen humidification bottle is communicated with the gas outlet of air storing cavity.
The beneficial effects of the utility model: oxygen pillow of the present utility model, comprise the air storing cavity surrounded by hard shell, the soft bullet pad be enclosed in outside hard shell stretches into one end the air tube be communicated with the gas outlet of air storing cavity in soft bullet bed course, described hard shell is provided with the intake valve of air storing cavity, described intake valve is worn to outside soft bullet pad, be provided with the piston airtight with it in described air storing cavity, described piston be connected with the piston rod extend out to outside soft bullet pad., promoting reciprocating motion of the pistons by piston rod, can increase oxygen flow when tolerance constantly reduces in air storing cavity, is the flow supply patient that oxygen keeps relative temperature.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in the figure: the oxygen pillow of the present embodiment, comprise the air storing cavity 2 surrounded by hard shell 1, the soft bullet pad 3 be enclosed in outside hard shell stretches into one end the air tube 4 be communicated with the gas outlet 21 of air storing cavity 2 in soft bullet bed course, air tube 4 is provided with flow control valve, described hard shell 1 is provided with the intake valve 5 of air storing cavity, described intake valve 5 is worn to outside soft bullet pad 3, be provided with the piston 6 airtight with it in described air storing cavity 2, described piston 6 be connected with the piston rod 7 extend out to outside soft bullet pad.Adopting hard shell 1 as the shell of air storing cavity 2, promote piston 6 move back and forth by piston rod 7, can increase oxygen flow when tolerance constantly reduces in air storing cavity 2, is the flow supply patient that oxygen keeps relative temperature.
The motion of above-mentioned piston 6 relies on piston rod to be completed by artificial or other equipment such as cylinder etc., uses the artificial piston rod 7 that promotes to increase Operating Complexity, uses the equipment such as cylinder to promote piston rod 7 complex structures, produce, use cost is high.For this reason, between piston 6 end face and hard shell 1, be provided with spring 8, when to gas storage interacvity air-filling, described spring 8 is constantly compressed, after inflation, spring 8 is compressed into minimum length, and in venting and patients accepting oxygen inhalation process, the compression elasticity of spring 8 constantly discharges, promote piston 6 to move to gas outlet 21, the oxygen enable still is extruded to outside air storing cavity 2 with larger flow, and structure is simple, without the need to manual operation.Certainly also there is certain limitation in this spline structure, and namely the natural length of spring is limited, and when the oxygen in air storing cavity is reduced to after spring is in natural length, piston cannot continue to move to gas outlet 21.For this reason, piston 6 is made up of first piston body 61 and the second piston body 62, described second piston body is relatively near gas outlet 21, first piston body 61 is provided with groove, and the second piston body 62 is provided with the projection of the groove embedded on first piston body, piston rod 7 is connected with the second piston body 62 through after first piston body, spring 8 is between first piston body 61 and hard shell 1, in oxygen pillow during inflation, under gas pressure first, second piston body moves and Compress Spring 8 together, patients accepting oxygen inhalation makes the thrust of spring 8 discharge and makes first, second piston body moves to gas outlet 21 simultaneously, when spring in the raw after, operated piston bar 7 makes it drive the second piston body 62 to extrude oxygen and enters air tube again, can oxygen flow be kept relatively for a long time constant.
As the further improvement of technique scheme, the side of described soft bullet pad 3 relative harder housing is provided with groove 31, oxygen humidification bottle 9 is provided with in described groove 31, the outlet 91 of described oxygen humidification bottle 9 is connected with air tube 4, the entrance 92 of described oxygen humidification bottle 9 is communicated with the gas outlet 21 of air storing cavity 2, oxygen after humidifying enters in patient body again, and patient is more comfortable.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
