Description  (OCR text may contain errors)

,amount only of heated water is permitted to flow'through said coil the loss of heat from zsaid coil byradiation will be so great, com- -pared tothe amount of heat received from the water, that said coil will become com para- ,tivelycooL It is obvious that if the ilow were completely checked the temperature of the jLfoil n would fall to approximately the temperature of the surrounding atmosphere; It is evident. that the cock q may with the same result be placed atany point in the coil n or tubes connected thereto.

By the construction of the parts here shown the'r c oil n. may be disconnected from the ring c, and the vessel ct may also be removed t' rom said ring, thereby facilitating cleansing ofthe parts, particularly of said Vessel.

` -v The vessel ci is'closed by means of .the removable cover s, which lits over the Ilange b andmakes a practically air-tight joint therewith. Said cover s is provided with the funnel-.shaped vopening t, across the mouth of which extends the metallic sieve u.4 Said opening s is adapted to receivea small quantity of surgeons cotton, which acts as a'ilter to purify the air entering the vessel a., said cotton resting upon the sieve u, above mentionecL 'ervoir p is supplied with water at a temperature equallto or greater than the temperatreatqwhich itv is desired to maintain the` solution to be transfused. The vessel ais.

filled-with thesolution for transfusion and the-parts assembled as abovedescribed, the

.I'QSBI'Voir p being so arranged that Water will flow jtherefrom to and through the coil n. The heated Water passingthrough the coil a imparts its-heat to the latter', and the heat of 'ihecoilis transmitted through the side ofthe vessel .a to the solution contained therein.

l Byregnlating-the ilowol water through the seL and the solution isallowedv-toaowth coilbyz-means 'of 4the c'ock q the temperature. ofrthe. solution in the vessel aisjgoverned.

WVhen thesolntionis at the proper temperature, the extremities h h of the point-.s gg arel inserted into the' tissues or-veiuls.'ofthe l'OOdy Water in the reservoir 19 and regulating the flow through., the coila the temperature of the solution may be maintained constant even though the temperature of the Water in said reservoir should vary considerably. l

The pointy: (shown in Fig. 4) is designed for use when the solution is to betransfused into the veins, and consists, preferably,.of glass. The method of operation when employing this last-mentioned point is substantially the same as the method of operation above described.

It is obvious that the number of points in use at any time is immaterial iu so` far as the principle of operation of our apparatus is concerned.

Vhat we claim as new., and desire to secure by Letters Patent, is-

l. In a transfuser, the combination of a vessel for containing the liquid -for transfusion, a detachable ring or hoop for encircling i said vessel, means for controllably transfusing the liquid from said vessel into the bloodpassages, and a cover for said vessel provided with a Iilterfor removing impurities from the air entering said vessel during transfusion.

3. In a transfuser, the combination of a vessel for vcontaining the liquid for transfusion, means for transfusing the liquid from said vessel into the blood-passages, a tube coiled to conform approximately to the exterior surface of said vessel, a ring or hoop removably supporting said -vessel, means for suspending said ring or hoop, hooks on said ring or hoop for detachably suspending said coil in proximity to and around said vessel,

and means for controllably supplying liquid to vsaid co.
