Description
Technical field
The invention belongs to technical field of medical instruments, specifically refer to a kind of Medical oxygen bag.
Background technology
Oxygen bag is the buoyant apparatus commonly used clinically, in use along with in oxygen bag the reduction oxygen flow of pressure be gradually reduced, when external and internal pressure reaches poised state, oxygen in oxygen bag cannot be discharged, now need artificially to extrude oxygen bag, and adopting the mode of artificial extruding, its extruding force is difficult to determine and causes the suddenly big or suddenly small of oxygen stream, have impact on rescue efficiency.
Summary of the invention
It is an object of the invention to provide a kind of Medical oxygen bag that can automatically adjust pressure, control oxygen flow.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: Medical oxygen bag, it includes the bag of a sealing, oxygenation mouth and oxygen exhaust it is provided with in bag front end, oxygen exhaust connects Oxygen tube, it is characterized in that: also include a pressure regulation device, described pressure regulation device includes the cylindrical cavity of a closed at both ends, bag outlet in the axial direction is had on the surface of cylindrical cavity, it is provided with the rotating shaft parallel with chamber axis in the inside of cylindrical cavity, rotating shaft is wound around the reed that can tighten up or expand, one end of reed and rotating shaft are fixed, the other end of reed and the end clamping sealing bag, seal bag to pass through the bag outlet pull-out cavity on cylindrical cavity surface or be wrapped in rotating shaft.
Further, the bag edge upper connecting rod of described sealing bag front end, the length that the length of pull bar exports more than bag.
Further, the outlet of described bag is provided with to the outside guided plate up and down extended of cylindrical cavity, and upper and lower guided plate is separately fixed at the lower edges of bag outlet and arranges in splayed.
Further, one end of described rotating shaft is stretched out the end of cylindrical cavity and is formed axle stretch end, and is provided with rotary handle on axle stretch end.
Further, described rotary handle is provided with ratchet, and is provided with ratchet on the end face of corresponding cylindrical cavity, and ratchet is separable with ratchet or is engaged.
This Medical oxygen bag, by adopting after said structure, can adjust the pressure of oxygen bag by automatic or manual in oxygen uptake process, it is ensured that stablizing of oxygen supply air-flow, be effectively increased efficiency of oxygen supply.
Accompanying drawing explanation
Accompanying drawing 1 pulls out the structural representation after cylindrical cavity for bag.
Accompanying drawing 2 is contracted to the structural representation in cylindrical cavity for bag.
Accompanying drawing 3 is contracted to the structural representation of rotating shaft and reed after cylindrical cavity for bag.
Accompanying drawing 4 is the structural representation of rotating shaft and reed after bag pull-out cylindrical cavity.
The structural representation that accompanying drawing 5 exports for cylindrical cavity bag.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, Medical oxygen bag, it includes the bag 1 of a sealing, is provided with oxygenation mouth 2 and oxygen exhaust 3 in bag front end, and oxygen exhaust connects Oxygen tube 4.
As shown in accompanying drawing 1 and accompanying drawing 2, also include a pressure regulation device, this pressure regulation device includes the cylindrical cavity 5 of a closed at both ends, bag outlet 6 in the axial direction is had on the surface of cylindrical cavity, being provided with this rotating shaft 7 of the rotating shaft 7(parallel with chamber axis in the inside of cylindrical cavity invisible in accompanying drawing 1 and accompanying drawing 2, the two ends of rotating shaft are supported on the end face at cylindrical cavity 5 two ends free to rotate).
Shown in accompanying drawing 3 and accompanying drawing 4, rotating shaft 7 being wound around the reed 8 that can tighten up or expand, one end of reed is fixed with rotating shaft 7, the end clamping of the other end of reed 8 and sealing bag 1.
Shown in accompanying drawing 3 and accompanying drawing 4, after sealing bag 1 pulls out cylindrical cavity, reed 8 shrinks and rotating shaft 7 clamping, and after sealing bag loses expansive force, sealing bag 1 is slowly drawn in cylindrical cavity inside and is wrapped in rotating shaft 7 with reed 8 by bag by reed 8 automatic expansion.
For preventing inside the overall indentation cylindrical cavity of bag 1, as shown in accompanying drawing 1-4, at the bag edge upper connecting rod 9 sealing bag front end, the length of pull bar 9 exports the length of 6 more than bag.Such bag 1 is behind indentation cylindrical cavity inside, and pull bar 9 is isolated in the outside of bag outlet 6 to facilitate pull-out next time bag to carry out oxygenation operation.
By foregoing description, the work process of this Medical oxygen bag is: bag is carried out oxygenation by oxygenation mouth 2 by pull-out bag 1, bag body expansion also maintains certain pressure, now bag is integrally located at outside cylindrical cavity, and when carrying out oxygen uptake operation, along with the reduction of pressure in bag, bag is deflated, now bag end is from the internal indentation of trend cylindrical cavity under the effect of reed, and the pressure in bag is maintained, it is ensured that the stable output of oxygen exhaust oxygen supply air-flow.
For making sealing bag stably enter inside cylindrical cavity, as shown in Figure 5, the lower edges of the bag outlet 6 on cylindrical cavity is respectively provided with guided plate 10-1 and lower guided plate 10-2, and upper and lower guided plate is that splayed is arranged.After increasing upper and lower guided plate, one is the entrance thickness that can change and seal bag, and sealing bag end has one to gradually taper up thinning process, it is ensured that bag steadily enters inside cavity；Two is to prevent under the effect of reed, and sealing bag end is made a forcible entry into cavity and caused the scuffing to bag of the bag outlet edge.
As shown in Figure 1, this Medical oxygen bag is also provided with manual pressure device, the setting of this manual pressure device is that the end that one end of rotating shaft 7 is stretched out cylindrical cavity forms axle stretch end, and on axle stretch end, it is provided with rotary handle 11, the pressure size in bag can be sealed by Non-follow control by controlling the rotation of rotary handle 11.Be simultaneously realize further manually with conversion automatically, as shown in Figure 1, rotary handle 11 is provided with ratchet 12, and is provided with ratchet 13 on the end face of corresponding cylindrical cavity, by ratchet 13 and ratchet 12 separate or be engaged realization manually with automatically change.
