Application July 27, 1946, Serial No. 686,637
My invention relates to the administration of anesthesia.
It is the object of this invention to provide a differential anesthesia valve.
It is the object of the invention to provide a valve that makes possible the alternate administration of two intravenous solutions.
It is a further object of the invention to provide all adjustments so localized at one point as to make it possible for closer attention to the patient with less necessary attention to the apparatus on the part of the physician.
It is a further object of the invention to provide a valve that has relatively large apertures to facilitate cleaning.
It is a further important object of the valve to make it impossible to mix the solutions within the valve.
It is the object of this invention to provide a valve with a single passageway to the patient, allowing communication between the syringe and the patient only, when administering anesthesia.
It is a further object to provide a valve in which the movement of the single passageway and the connecting of the syringe to a reservoir of one material is effected; or the movement of the valve can be efiected for the connection of the syringe to another material. In either event it is impossible to mix the materials on their Way to the patient.
It is a further object to alternately connect a solution to the patient and when one of such solutions is so connected, a charge of another solution is prepared for administration.
Referring to the drawings;
Figure l is an isometric perspective of the valve, the syringe, a supply of pentothal, a supply of saline solution and the arm of the patient receiving the material.
Figure 2 is a section through the valve with an elevation of the syringe showing the valve in position for connection to the patient to the saline solution while the syringe is connected to the pentothal supply.
Figure 3 is a similar view to Figure 2 showing the valve in position for the discharge from the syringe of the pentothal charge to the patient while the saline solution has been shut ofi from the patient.
Figure 4 is a vertical section through the valve on line 4-4 of Figure 3 indicating its construction and method of operation.
Figure 5 is a top plan view of the valve, showing in detail its direction indicator.
a valve body having a port 2, communicating with a pipe 3, constituting a connector for the rubber pipe 4 that in turn is connected suitably to the arm of the patient for intravenous application of the fluids hereinafter referred to.
The arm of the patinet is designated 5 and the attachment of the pipe 4 is illustrated diagrammatically. The exact means of injection is of no interest in connection with this invention.
6 is a port in the valve body I which communicates with the connector I, that in turn supports the rubber pipe 8 that is connected to a supply 9 of pentothal.
The port In in the valve body I is connected to a connector I l which in turn supports the syringe l2. The actuation of the plunger l2a of the syringe [2 serves to draw the pentothal into the syringe body and also serves to eject it at the suitable moment.
The passageway l3 in the valve body I is connected to the connector [4 which in turn supports the rubber tube l5 that is connected to a saline solution container [6.
The valve member I! is provided with a cutaway portion IB to form a passageway that will interconnect the several ports inside of the valve body I A similar cutaway passageway is formed at 19. These internal passageways serve to place source of supply and the patient in direct contact with one another or to connect the source of supply of pentothal to the syringe. It will be observed that in either way it is possible to conduct the fluid either to the patient or to the syringe without any possibility of a mixture of the two.
A central passageway 20 is provided through the valve body which is adapted to connect the syringe to the patient. In such a position there is no possibility of any connection of the saline solution to the patient at the time the pentothal is being injected. The valve member I! will carry the handle 2! and is provided with an indicator arrow 22 and an indicator as to the position of the valve passageways at 23 and 24. The valve member is mounted upon a sealing ring 26 and is retained by retaining set screw 21. A suitable seal 28 is provided below the valve.
The novel feature of this invention resides in the ability, with a single handle, to connect the patient to the saline solution or connect the patient to the source of pentothal or other material without any possibility of mixture. The further advantage is that while the patient is receiving the saline solution, a measured quantity of pentothal can be withdrawn from the Referring to the drawings in detail, I designates container 9 into the syringe l2 ready for the next 3 operation of injecting the pentothal into the patient. In this manner the single hand of the physician or nurse may be employed for the purpose of complete regulation of the application of the several fluids involved with no possibility of mixture or mistake.
It will be thus seen that I provide a valve which makes possible the alternate administration of 2 intravenous solutions all adjustments localized atone. point; making it possible to. givecloser attention to the patient with less necessary attention to the apparatus. The valve itself has. relatively large apertures which facilitate clearring and they are so arranged that! it... is;impos'- sible to mix a solution within the valve.
It will be understood that desire to com prehend within my invention such. modificationsas may be necessary to adapt the invention to various conditions of use, all within the scope of the hereinafter appended claims.
