GAS DISPENSING DEVICE. APPLICATION FILED APR.9. 1914.

Fly/14422}? RICHARD M. BOLTON, o oHIoAGo, ILLINOIS.
' "GAS-DISPENSING DEVICE.-
Specification of Letters Patent.
npplicationfiled Apri19,1914. Serial No. 830,686. a
Be it known that I, RICHARD BoL'roN,
a citizen of the United States, and a resident of the city of vChicago,county of Cook, and
State of Illinois, have invented certain new and useful Improvements in Gas-Dispensing Devices, of which the following is a specification.
My invention relates to means for administering gases and the like for medical purposes and the object of my improvement is the production of a simple and effective device of the character mentioned which is particularly adapted for use in administering gases to patients in dentistry for producing analgesia and anesthesia.
Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and claimed. 7
The invention will be best understood by 'reference to the accompanying drawing forming a tially air tight joint between the face of a.
part of this specification, and in Which Figure 1 is a view, in perspective, illustrating the application of a. device which embodies my invention, for administering gases for medicinal purposes, Fig. 2 is an enlarged front View of the device showing the securing band and one of the feeding tubes broken away. and the other feeding tube entirely removed, and Fig. 3 is a cen tral vertical section of the device.
The preferred form of construction as illustrated in the drawing comprises a hollow body 4 having its rear side open and such rear side shaped to fit over the nose of a patient in order to restrict the passage of air into or out of said body. A cushion 5 is se: cured around the opening in the rear of body 4 and is adapted to form'a substanperson and the body 1. The cushion 5 may be so shaped that it will be held to the body etby friction or. it may be secured with a suitable adhesive, such as glue.
Near the upper ends of the lateral walls of the body t are openings 6 adapted for the passage of the gases 'to be used into the device. On the lateral walls of body a are provided nipples 7 which are preferably formed integral with said walls and adapted to receive the ends of fiexibletubesfi. The tubes '8 may be of soft rubber or any other suitable substance. As indicated in'Fig. 1 the tubes 8 are brought together at a convenient dising from the spirit of the invention. therefore, do not wish to be limited to the tance from the device and engaged on a connection 9. The connection 9 is connected to a source of gas supply, not shown, by means of tube 10. i
A discharge opening is formed in the lower side of the front wall 11 of body t and substantially on a line with the nostrils of a patient when the device is in operative condition in order to form as straight and short a passage from the nostrils as possible. In the opening in the wall 11 is threaded a hollow plug 12 having a shoulder 13 adapted to engage a plate 1% which is disposed across the front of the body 1. The arrangement is such that the plug 12 is threaded in the opening in wall 11 and securely binds plate 1-1 in position. On the outer side of plug 12 is provided a flap valve 15 secured to the plug 12 by means of a screw 16, or its equivalent.
At each end of plate 1 1 is an eye 17 and in each eye is the end'of a flexible band 18. Said flexible band is adapted to'pass around the head of a patient in order to maintain the device in operative condition.
In operation the device is applied to the face of a patient substantially as indicated in Fig. 1 and pipe 10 connected with a suitable source of gas supply (not shown). The gas-in passing through openings 6 enters the upper portion of the chamber in body a and passes around the nose of a patient to his nostrils. In exhaling the flap valve 15 is flexed outwardly permitting the patients breath to escape through the perforation of plug 12. As soon as the patient is through exhaling and begins to inhale, the gas is drawn through openings again and this operation continued during use of the device. A further reason for placing the openings 6 high up in the body at is to permit the positioning of tubes 8 away from the mouth of the patient and to'take them away from the head and neck of the patient. This permits the dentist to have free access to the mouth of the patient.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without deparpprecise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.
