and useful improvements in Surgical Appliances, of which the iication' ihiy present invention pertains to surgicz-il appliances and it contemplates the pro vision of a device whereby any portion of the liquid contained in a vacuum vessel,
such for instance, the well known thermos bottle, may be removed without lowering the temperature of the contents remaining in the vessel.
My novel appliance is highly eiiicient when used for and in connection with intervenous injections, the ll lurphy drip method or the Dakin Carroll solution, and where an irrigator is used it being especially advantageous to maintain the solution at a high and even temperature during said injections.
lin order that those skilled in the art will be fully aware of the advantages of my novel device, I deem it well to state that heretofore it has been the custom to place the heated solution into an irrigator, in which the solution quickly cools and it is very difficult to keep the solution at an oven temperature while in use, which is an absolute necessity.
Experience has demonstrated that this cooling of the solution has on many occasions been attended with disastrous resuits and it is the purpose ofmy novel device to overcome such disadvantages.
The invention in all of its details will be fully understood from the following description and claim when the same is read in connection with the drawings, accompanyingand forming part of this specification, in which:
Figure l is a side elevation showing my novel appliance arran red on the well-known thermos or vacuum bottle.
Figure 2 is asectional view oi Figure 1.
Similar numerals of reference designate corresponding parts in all of the views of the drawings.
in order to more readily disclose my invention, 1 have illustrated the same as applied to a thermos bottle of the ordinary my invention is applied to :iollowinp; is a speci-- construction as indicated. by l and having the cap 2, inner bottle 3, washer i, and the cork or stopper 5. The bottle forms no part of myinvention and in this connection 1 would have itdistinctly understoodthat any form of vacuum vessel or pain 7,
As illustrated by Figure 2,, l drill or otherwise cut, the longitudinal openings through the cork or stopper 5 and in the upper end ofthe cap 2, I provide openin q's that register with those or the cork} into the openings in the. cork and cap and thence into'the slots 6, I insert my novel glass tubes 7 and 8.
The tube 7 is for the admission of air so as to permit the fluid to :t'reely flow from the container; This tube 7 is provided with the outwardly directed portion 7 and the downwardly directed portion 9 of the end of which, when deemed necessary, a cap 10 of rubber or other material may be placed.
The cap 10 is employed to prevent the possibility of air entering the bottle. owever, experience has demonstrated that because of its construction, the tube 7 will preclude entry into the container of air when said container is standing in the position illustrated by the drawings.
The tube 8 is inserted into the remaining opening 6 of the cap and at its outer end 11 said tube maybe crimped to receive a hose or other conduit 12.
In the practical use of the appliance dur ing a venous or other injection, the cap 10 is removed from the portion 9 of tube 7 and the bottle tilted so that the cap 2 is placed in a downward position. Liquid will readily flow from the bottle through tube 8 and thence through conduit 12, where it may be injected into a patient.
it will be readily apparent that when the container is returned to its proper position, cooling of the liquid will be precluded.
Moreover, the necessity for removing the cap 2 and cork 5 is dispensed with and therefore the liability of a nurse or other attendant becoming so engrossed in the work that they will overlook returning the capland cork to the proper places is effectuallyprecluded.
Because'ofthe fact that air enters the bottle or container only during the actual use of the solution, and this being in such an infinitesimal degree liability of the solution becoming chilled to a dangerous degree is precluded.
I would distinctly have it understood that the openings 6 of the cork or stopper 5 are of such size as to snugly grip the tubes 7 and 8, and hence not'only will air be prevented from contacting with the solution by passing between the openings 6 and outerfsurfaces of the tubes 7 and 8, but during the tilting of the container, the tubes will be prevented from being displaced from the cork and thus broken by striking the floor or other surface.
Having described my invention, what I claim and desire to secure by Letters-Patent,
In a surgical appliance, the combination of a vacuum vessel, a closure for said vessel, a cap secured on the vessel and having apertures therein, two channels formed in said closure and extending the full length thereof and adapted to communicate with the apertures of the cap and atmosphere, a
reaching portion that extends at an angle to the portion of the tube held in the closure whereby when the vessel is standing in its upright position the effect of atmosphere on the temperature of the contents of said vessel will be extremely slow and when the vessel is tilted the contents will flow from the first named tube. v
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
