Definitions
- This invention relates generally to resuscitation devices and pertains more particularly to a portable type of respirator operated entirely by the person administering the artificial respiration.
- a very effective way to administer artificial respiration is by directly inflating the patients lungs orally. Naturally, this is somewhat unsanitary if the respiration is directly from mouth to mouth and loses somewhat of its eflect due to the fact that the air expelled from the lungs of the person administering the respiration is not of as high oxygen content as would be fresh air.
- Another object of this invention is to provide a relatively small and self-contained respirator assembly whereby artificial respiration may be administered quickly and effectively with a minimum of skill on the part of the operator.
- a further object of this invention is to provide a respirator assembly which is extremely compact in form and con struction, thus being economical while yet at the same time being completely and fully effective for the purposes intended and desired.
- Another object of this invention is to provide an artificial respiration device in the form of a relatively small cylinder divided interiorly into separate compartments by a flexible diaphragm and each having exterior communication to the atmosphere so that air expelled through and into the device on one side of the diaphragm will correspondingly expel air from the other side of the diaphragm without communication between the two chambers.
- a further object of this invention is to provide an artificial respiration device in conformity with the preceding object wherein one side of the diaphragm has an auxiliary fresh air inlet which is manually controlled to permit fresh air always to be drawn into that corresponding side of the diaphragm for expulsion through a patients mouth into the lungs thereof.
- a further object of this invention is to provide an artificial respiration device comprising essentially an elongate chamber having its interior divided into isolated chambers by means of a flexble diaphragm, one of the chambers having an air inlet opening thereinto in the form of a mouth piece so that a person administering the respiration may breathe directly into the chamber for moving the diaphragm to displace air from the other chamber, and wherein the other chamber is provided with an outlet in the form of a tongue depressor and having fresh air inlet means manually controlled to assure the entrance of fresh air into the chamber associated with the patients mouth piece.
- Another object of this invention is to provide an artificial respirating device in conformity with the immediately preceding object wherein the tongue depressor mouth piece for the patient is provided with a cushioned plate surrounding the same and of generally arcuate form so as to seal the patients mouth opening about the mouth piece.
- FIG. 1 is a side elevational view of the respirating device constructed in accordance with this invention and showing the external details thereof;

- the self-contained and portable respirator assembly shown therein is indicated generally by the reference character 10 and will be seen to include a pair of complementary half sections 11 and 12 forming together an elongate cylinder-like member.
- the cylinder halves may be made of synthetic resin plastic material.
- the upper section 11 is provided with a mouth piece indicated generally by the reference character 13 and the lower section 12 is provided with a tongue depressor assembly indicated generally by the reference character 14.
- the upper and lower sections 11 and 12 are separable.
- the lower section 12 may be provided with an annular rim 15 at the open end thereof, which rim or bead has its inner surface provided with a circumferentially extending groove 16 formed between the inner wall surface 17 of the lower section and an inwardly projecting rib 18 on the inner side and at the upper extremity of the rim or bead 15.
- the rib 18 defines an internal diameter which is just slightly greater than the external diameter of the upper section 11 which it surrounds.
- the upper section :11 is provided at its lower extremity or open end thereof with an enlarged bead portion 19 whose external diameter is greater than the internal diameter of the rib 18 previously described sothat when the two parts are interengaged in the manner shown in FIG. 2, a locking action, preventing separation between the sections, is achieved.
- a flexible air separator diaphragm indicated generally by the reference character 20, is held in place within the device through the coupling interaction between the upper and lower sections 11 and 12.
- the reference character 20 is held in place within the device through the coupling interaction between the upper and lower sections 11 and 12.
- the air separator or diaphragm assembly itself is of configuration similar to the finger of a glove and is, of course, formed from air impermeable flexible material such as rubber or polyethylene or similar material.
- the air separator is large enough so that its volume is actually greater than the volume of either of the section halves 11 and 12. The purpose of this will be presently ap parent.
- the mouth piece 13 has a neck portion 22 communicating with the interior of the section 11 and terminates in an enlarged rim portion 23 so that the mouth piece may be comfortably placed within a persons mouth.
- the tongue depressor assembly 14 will be seen to include a neck portion 24 terminating in a flattened, slightly arcuate head 25, there being a passageway 26 extending axially through the tongue depressor communicating with the interior of the section 12.
- An air inlet tube 27 is provided for the purpose of by-passing the passageway 26 through the tongue depressor, the tube 27 having a passageway 28 intersecting the passageway 26 adjacent its juncture with the section 12.
- the tongue depressor 14 is also provided with an arcuate plate 29 joined with the neck 24 thereof and being provided with resilient material 30 such as foam rubber or the like on the concave face thereof.
- the tongue depressor 14 is placed in the patients mouth, the flattened head thereof being used to depress the patients tongue and hold it firmly in place during the respirating procedure.
- the person administering the respiration places the mouth piece 13 in their mouth and expels air into the section 11, displacing the diaphragm or air separator 20 from the full line position shown in FIG. 2 to the dotted line position shown therein.
- This movement of the diaphragm expels air from the interior of the device through the tongue depressor 14 inflating the patients lungs.
- the person administering the respiration places one of their fingers over the end of the tube 27 preventing escape of the air through the tube and assuring that the expelled air will be directed into the patients mouth.
- the plate 29 and the resilient material are pressed lightly against the patients mouth to prevent air escaping from around the tongue depressor.
- the next step in the cycle of operations is to remove the finger from the tube 27 permitting the patients lungs to expel air through the tube while at the same time the person administering the respiration maintains sufficient pressure against the diaphragm or air separator 20 so as to prevent its moving from the dotted line position shown in FIG. 2.
- the person administeringthe respiration breathes in, thus drawing the diaphragm back to the full line position shown in FIG. 2, his fingers still being out of contact with the tube 27 permitting fresh air to be drawn into the device through the tube.
- the person administering the respiration may then take a quick breath of fresh air and repeat the cycle of operations, doing so in a rhythmic manner as long as is required and necessary.
- the air separator or diaphragm 20 is of slightly larger volume than either of the sections 11 or 12. The reason for this is to permit the same to be easily displaced between the full and dotted line position shown in FIG. 2 without requiring stretching of the diaphragm which would require, of course, the expenditure of additional effort on the part of the operator.
- the diaphragm or air separator 20 positively assures at all times that the patient and operator do not breathe the same air and permits, through the medium of the air inlet tube 27, the charging of the device with fresh air for expulsion into the patients lungs, thus not only assuring sanitary conditions but also assuring effective operation since the fresh air will have a much higher oxygen content than that expelled from the operators lungs,

I. H. ROBERSON PORTABLE ARTIFICIAL RESPIRATOR June 5, 1962 Filed Dec. 8, 1959 FIG.I
3,037,497 PORTABLE ARTIFICIAL RESPIRATOR Ida Harte: Roberson, Rte. 5, Box 452, Savannah, Ga. Filed Dec. 8, 1959, Ser. No. 858,191 7 Claims. (Cl. 128-29) This invention relates generally to resuscitation devices and pertains more particularly to a portable type of respirator operated entirely by the person administering the artificial respiration. i
A very effective way to administer artificial respiration is by directly inflating the patients lungs orally. Naturally, this is somewhat unsanitary if the respiration is directly from mouth to mouth and loses somewhat of its eflect due to the fact that the air expelled from the lungs of the person administering the respiration is not of as high oxygen content as would be fresh air. It is, therefore, of primary concern in connection with this invention not only to provide an artificial respiration device which is portable and which requires no source of power for operating t other than the person administering the artificial respiration but also to provide a device which is sanitary and which assures the administering of fresh air to the person being resuscitated Another object of this invention is to provide a relatively small and self-contained respirator assembly whereby artificial respiration may be administered quickly and effectively with a minimum of skill on the part of the operator.
A further object of this invention is to provide a respirator assembly which is extremely compact in form and con struction, thus being economical while yet at the same time being completely and fully effective for the purposes intended and desired.
Another object of this invention is to provide an artificial respiration device in the form of a relatively small cylinder divided interiorly into separate compartments by a flexible diaphragm and each having exterior communication to the atmosphere so that air expelled through and into the device on one side of the diaphragm will correspondingly expel air from the other side of the diaphragm without communication between the two chambers.
A further object of this invention is to provide an artificial respiration device in conformity with the preceding object wherein one side of the diaphragm has an auxiliary fresh air inlet which is manually controlled to permit fresh air always to be drawn into that corresponding side of the diaphragm for expulsion through a patients mouth into the lungs thereof.
A further object of this invention is to provide an artificial respiration device comprising essentially an elongate chamber having its interior divided into isolated chambers by means of a flexble diaphragm, one of the chambers having an air inlet opening thereinto in the form of a mouth piece so that a person administering the respiration may breathe directly into the chamber for moving the diaphragm to displace air from the other chamber, and wherein the other chamber is provided with an outlet in the form of a tongue depressor and having fresh air inlet means manually controlled to assure the entrance of fresh air into the chamber associated with the patients mouth piece.
Another object of this invention is to provide an artificial respirating device in conformity with the immediately preceding object wherein the tongue depressor mouth piece for the patient is provided with a cushioned plate surrounding the same and of generally arcuate form so as to seal the patients mouth opening about the mouth piece.
As this invention may be embodied in several forms without departing from the spirit or essential characteris- Ilnite States Patent ice tics thereof, the present embodiment is therefore illustrative and not restrictive, and since the scope of the invention is defined by the appended claims, all changes that fall within the metes and bounds of the claims or that form their functional as well as conjointly cooperative equivalents are therefore intended to be embraced by those claims.
In the drawing:
FIG. 1 is a side elevational view of the respirating device constructed in accordance with this invention and showing the external details thereof; and
FIG. 2 is a longitudinal section taken through the assembly shown in FIG. 1, and illustrating details of its internal construction as well as further details of external construction thereof.
Referring at this time more particularly to FIG. 1, the self-contained and portable respirator assembly shown therein is indicated generally by the reference character 10 and will be seen to include a pair of complementary half sections 11 and 12 forming together an elongate cylinder-like member. For purposes of economy, the cylinder halves may be made of synthetic resin plastic material. The upper section 11 is provided with a mouth piece indicated generally by the reference character 13 and the lower section 12 is provided with a tongue depressor assembly indicated generally by the reference character 14.
As can be seen most clearly in FIG. 2, the upper and lower sections 11 and 12 are separable. For this purpose, the lower section 12 may be provided with an annular rim 15 at the open end thereof, which rim or bead has its inner surface provided with a circumferentially extending groove 16 formed between the inner wall surface 17 of the lower section and an inwardly projecting rib 18 on the inner side and at the upper extremity of the rim or bead 15. The rib 18 defines an internal diameter which is just slightly greater than the external diameter of the upper section 11 which it surrounds.
The upper section :11 is provided at its lower extremity or open end thereof with an enlarged bead portion 19 whose external diameter is greater than the internal diameter of the rib 18 previously described sothat when the two parts are interengaged in the manner shown in FIG. 2, a locking action, preventing separation between the sections, is achieved.
A flexible air separator diaphragm, indicated generally by the reference character 20, is held in place within the device through the coupling interaction between the upper and lower sections 11 and 12. For this purpose, the
The air separator or diaphragm assembly itself is of configuration similar to the finger of a glove and is, of course, formed from air impermeable flexible material such as rubber or polyethylene or similar material. The air separator is large enough so that its volume is actually greater than the volume of either of the section halves 11 and 12. The purpose of this will be presently ap parent.
The mouth piece 13 has a neck portion 22 communicating with the interior of the section 11 and terminates in an enlarged rim portion 23 so that the mouth piece may be comfortably placed within a persons mouth.
At the opposite end of the device, on the lower extremity of the section 12, the tongue depressor assembly 14 will be seen to include a neck portion 24 terminating in a flattened, slightly arcuate head 25, there being a passageway 26 extending axially through the tongue depressor communicating with the interior of the section 12. An air inlet tube 27 is provided for the purpose of by-passing the passageway 26 through the tongue depressor, the tube 27 having a passageway 28 intersecting the passageway 26 adjacent its juncture with the section 12. The tongue depressor 14 is also provided with an arcuate plate 29 joined with the neck 24 thereof and being provided with resilient material 30 such as foam rubber or the like on the concave face thereof.
In use, the tongue depressor 14 is placed in the patients mouth, the flattened head thereof being used to depress the patients tongue and hold it firmly in place during the respirating procedure. The person administering the respiration places the mouth piece 13 in their mouth and expels air into the section 11, displacing the diaphragm or air separator 20 from the full line position shown in FIG. 2 to the dotted line position shown therein. This movement of the diaphragm expels air from the interior of the device through the tongue depressor 14 inflating the patients lungs. During this period, the person administering the respiration places one of their fingers over the end of the tube 27 preventing escape of the air through the tube and assuring that the expelled air will be directed into the patients mouth. Of course, the plate 29 and the resilient material are pressed lightly against the patients mouth to prevent air escaping from around the tongue depressor.
The next step in the cycle of operations is to remove the finger from the tube 27 permitting the patients lungs to expel air through the tube while at the same time the person administering the respiration maintains sufficient pressure against the diaphragm or air separator 20 so as to prevent its moving from the dotted line position shown in FIG. 2. As soon as the patients lungs have expelled the air, the person administeringthe respiration breathes in, thus drawing the diaphragm back to the full line position shown in FIG. 2, his fingers still being out of contact with the tube 27 permitting fresh air to be drawn into the device through the tube. The person administering the respiration may then take a quick breath of fresh air and repeat the cycle of operations, doing so in a rhythmic manner as long as is required and necessary.
As previously mentioned, the air separator or diaphragm 20 is of slightly larger volume than either of the sections 11 or 12. The reason for this is to permit the same to be easily displaced between the full and dotted line position shown in FIG. 2 without requiring stretching of the diaphragm which would require, of course, the expenditure of additional effort on the part of the operator.
The diaphragm or air separator 20 positively assures at all times that the patient and operator do not breathe the same air and permits, through the medium of the air inlet tube 27, the charging of the device with fresh air for expulsion into the patients lungs, thus not only assuring sanitary conditions but also assuring effective operation since the fresh air will have a much higher oxygen content than that expelled from the operators lungs,
