Abstract
The utility model belongs to medical instruments, and discloses an oxygen bag. A bag body is formed by connecting a flexible pipe end to end in a sealing mode to form a ring. An expanding device which passes through the circle center of the annular bag body is arranged in the inner circle of the annular bag body. The expanding device is formed by a sleeve pipe and expanding rods inserted in the two ends of the sleeve pipe. An expanding spring is arranged in the sleeve pipe, and the two ends of the expanding spring abut against the inner ends of the two expanding rods respectively. A one-way valve air tap is arranged on the outer side wall of the bag body. The oxygen bag is more stable in structure, and more balanced in stress, exploding or air leaking when air pressure is high can be avoided, air pressure in the bag body is sufficient all the time, and the purpose of stably and evenly supplying oxygen can be achieved.
Description
Technical field
This utility model relates to a kind of medical supplies, relates in particular to a kind of oxygen bag easy to use.
Background technology
Oxygen bag is clinically for storing the easy device of oxygen, and bag is sewed up or bonding forming by multi-disc PVC material conventionally, and inner hollow, is pincushion after inflation.Current this oxygen bag in use has the following disadvantages: (1) oxygen bag used after a period of time, and air pressure inside reduces gradually, oxygen can not be discharged smoothly, and affect oxygen supply effect; (2) it adopts two or multi-disc PVC material to be formed by connecting by the means such as sewing up or bonding conventionally, and connecting line is longer, has reduced its intensity, and in use procedure, easily explosion or junction leak gas; (3) its switch valve is arranged on exhaustor conventionally, can cause oxygen bag to reveal after exhaustor slippage, continues to use and affect it.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that this utility model provides, and easily implements, and can guarantee that oxygen evenly supplies with, and structure stablized durable oxygen bag more.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of oxygen bag, comprise a bag, it is characterized in that: described bag is tightly connected and is circularized and form by flexible pipe head and the tail, in the inner circle of the bag of annular, be provided with the stretching apparatus in its center of circle of process, described stretching apparatus is made up of sleeve pipe and the expanded support bar that is plugged in its two ends, in sleeve pipe, be provided with the expanded support spring that two ends are supported with two expanded support bar inner ends respectively, the lateral wall of described bag is provided with a check valve valve.
The utlity model has following beneficial effect: it adopts check valve valve, the inflation exhaust process ball with basketball, football etc. is identical, is inserted in check valve valve and can be inflated and aerofluxus by the air tube on exhaustor; It adopts flexible pipe to connect and compose, and only needs the bonding connection in a place, and junction is less, and structure is more stable, and adopts annular design, stressed more balanced, and explosion or gas leakage occur can avoid air pressure high time; In the middle of it, be provided with stretching apparatus, make bag be tending towards oval and change, guarantee that thus inside has sufficient air pressure all the time, reach object stable, balanced oxygen supply.
Accompanying drawing explanation
Fig. 1 is the structural representation while being full of oxygen in bag.
Fig. 2 is structural representation when oxygen is discharged in bag.
In figure, 1, bag, 2, expanded support spring, 3, sleeve pipe, 4, expanded support bar, 5, check valve valve.
The specific embodiment
Shown in Fig. 1,2, a kind of oxygen bag, comprise a bag 1, it is characterized in that: described bag 1 is tightly connected and is circularized and form by flexible pipe head and the tail, in the inner circle of the bag 1 of annular, be provided with the stretching apparatus in its center of circle of process, described stretching apparatus is made up of sleeve pipe 3 and the expanded support bar 4 that is plugged in its two ends, is provided with the expanded support spring 2 that two ends are supported with two expanded support bar 4 inner ends respectively in sleeve pipe 3, and the lateral wall of described bag 1 is provided with a check valve valve 5.
Described check valve valve 5 is identical with the gas nozzle structure of ball upper application, can on exhaustor, be provided with the air tube coordinating with check valve valve 5, insert in check valve valve 5 by air tube can inflate, aerofluxus, and after air tube extracts out, check valve valve 5 can stop the oxygen in bag 1 to be revealed; Stretching apparatus provides an expanded support power all the time to bag 1, makes that it is elongated in direction, other direction narrows, and is tending towards oval and changes, thereby guarantee to have stable air pressure in bag 1, reaches the object of stablizing oxygen supply.
