represented at 3. A cap Il preferably formed of In some instances the liquid which is to be adhard rubber or plastic material or other suitabler ministered from the bottle I must be passed material is provided with internal screw threadthrough a strainer before it enters the tubing on ing 5 on the inside of its cylindrical ilange or 3.3 its way to the injection needle. Such a strainer is represented at 2I. It is provided at its lower end with a hollow portion 22 which will fit snugly over theupwardly projecting portion I3 of the resilient member, the fit being such that the member I3 will be slightly compressed when the strainer portion 22 is forced thereover. The friction i'lt of the strainer on the part I3 provides an adequate attachment of the strainer to the cap wall also permitting the strainer to be readily removed from the cap when removal is desired. Similarly, a strainer may be readily applied to the cap whenever desired merely by pressing the strainer end over the projection I3, the application of the strainer being also somewhat facilitated by rotating the strainer while pressing it toward the disc portion I of the cap structure. The details of the strainer structure are not important in connection with the present invention, and for purposes of this application it is sufcient tomerely explain that inthe form of strainer illustrated, a ine mesh screen element 23 embodied in the upper portion of the strainer strains the liquid as it passes through the screen into the interior of the strainer.
The iitting I8 may be of stainless steel or other suitable material, and its construction in this instance comprises a tubular cylindrical portion 24 provided with a slightly flared inside entrance portion 25. At its opposite end the tubular portion 24 communicates with one end of a reduced passageway 26 the other end of which communicates with a larger or counterbored opening portion 21. A suitable ball valve member 28 is disposed in the enlarged opening portion 21 and is locked therein by one or more inwardly offset end portions of the fitting as indicated at 29. The L ball 28 is free to move in the direction of the axis of the fitting I8 so that when the ball rests on the shoulder between the openings 2B and 21, a passage of liquid downwardly through the opening 28 and the fitting I8 will be prevented. However, when air or other fluid is caused to'fiow upwardly through the fitting I8, the ball will be readily displaced upwardly to permit the passage ofsuch air or fluid upwardly through the fitting and into the bottle I. The ball 28 is, of course, of such size that when it is raised from the seat between the openings 26 and 21, fluid may pass upwardly around the ball.
The check valve end of the fitting I8 is provided with a circumferential rib or enlargement 38 which becomes embedded in the projection I1 to anchor the fitting to the resilient rubber element 9 of the cap structure.
In some instances, an air filter is applied to the fltting I8 as shown in connection with the cap structure` applied to the bottle'3l which is' connected by the ilexible tube 32 to the fitting I8 as shown in Fig. 1. In the illustration shown inFig. 1, the bottle 3| is connected to the bottle I through the tube 32 for the purpose of supplying additional liquid to the bottle I as is sometimes required where an extra large volume of liquid is to be injected into a patient. In many instances, the amount of liquid to be injected is no more than the quantity which a single bottle can hold in` which casethe tube'32 and second bottle 3l would not be employed. Instead of connecting a liquid supply tube 32 to the fitting i8,`
.an air filter would be applied directly to the` iitting I8 as shown inconnection with the fitting Ilia which is carried by the cap structure 4a for the bottle 3i. The cap structure 4a is the same as the cap structure 4, and the iltting I8a is the same as the iitting I8.
The air lter element consists of a berboard or paper tube 33 which is of such internal diameter as to be a snug friction fit on the main cylindrical portion 24 of the fitting I8 or I8a. The
paperboard tube is somewhat longer than the portion 24 of the fitting and has one end rebent inwardly as indicated at 34 to provide a retainer for a wad 35' of cotton or other suitable air ltering material. Such wad of cotton will, of course,
m be confined between the inturned end portion 34 of the filter tube and the outer end 36 of the fitting I8 or I8a. 'The paper lter element including the filter material therein is of such character that lt may be sterilized by heat or otherwise while in place von a cap structure,
sterilization by live steam being preferable a1- though not essential.
On the bottle I which represents the cap structure with associated elements for delivering uid to a patient, a sight tube or drip tube 31 is provided, said tube being of transparent material such as glass and being of such internal diameter as to fit snugly around the outside of the main body portion of the nozzle I4. The resiliency of the material of which the nozzle I4 is formed serves, of course, to permit some distortion or compression of the nozzle I4 to the end that a very tight and leak-proof t may be obtained etween the tube 3'! and the nozzle merely `by "a force t of the sight tube overthe nozzle.
A length of thermoplastic tubing 38 of suitable small diameter is secured at one end as shown at 39 to a reduced discharge end portion 40 of the sight tube and at its other end said tube 38 is provided with a needle adapter tting 4I. The fitting 4I may be made of stainless steel or other suitable metal construction, and it is so formed that the tube 38l may be securely united to the fitting by means of a leakproof joint. One suit- 40 able-construction is shown in my co-pending application Serial No. 671,736. The fitting 4I is provided with a tapered end portion 48 of such form that the usual injection needle may be attached thereto by more or less conventional means. A cap 42 is applied to the free end oi the needle adapter fitting 4i and is frictionally held thereon. Said cap may be of resilient rubber or other similar resilient material which can be easily removed when it is desired to attach a needle to the fitting. The material of which the cap 42 is formed should be of such material that it will withstand the effects of heat or other sterilizing procedure by which the entire cap structure with attached elements is sterilized.
A flow controlling -device is associated with the ilexible tubing 38. Said device comprises a sheet metal member 43 which is provided with a tapering slot 44 through whichthe tube 38 passes. By adjusting the slotted member 43 transversely of the tube 38, the tube wil1 be more or less closed as the tube is forced into the narrow end portion of the slot, thereby to restrict the flow of uid through the tube. At the wider end of the slot, it is of at least slightly smaller than the outside diameter of the tube, so that the latter will be compressed suiiicientlyy to cause the now controller to be eiectively held in place on the tube by the resiliency or expansive pressure of the tube. Gauge marks may be provided on the '10 `control device for indicating the setting thereof.
When a second bottle of fluid is to be connected to a rst bottle represented in Fig. 1, the cap structure 4a instead of having a sight tube such as 31 attached to its outletnozzle |4a is operative to receive a large sized needle-like tube 45 which may be inserted into the opening of the nozzle as Lshown. The t of the tube 45 in the nozzle opening is such that there will be no leak-v age possible between the nozzle and tube 45. The needle tube 45 has its outer end provided with an enlargement as shown at 48 for tightly receiving an end portion 41 of the connecting tube 32, the
other end of which is connected to the fitting I8 by means of an end fitting 4Ia which is of the same construction as the needle fitting 4I. The tapered end portion 48 of the fitting, which fits a portion of an injection needle, also fits snuglyv The principal unit according to the present in- 1 vention would comprise the cap structure 4 with the inlet fitting I8 and an air lter member 33 and filtering medium 35 on the fitting I8, a sight' tube 31 on the nozzle I4, a suitable length of tubing 38, the iiow control member 43 on the tube 38, the needle adapter fitting 4I attached to the tube 38, the protective cap or cover 42, and a protective cover 49 (Fig. 4) on the cap 4. This structure is represented in Figs. 4 and 5 of the drawings in a partially packaged condition. Such a principal unit of apparatus is capable of being sterilized in its assembled condition in an autoclave or other suitable sterilizing equipment. While being sterilized, the protective covers 42 and 49 should be in. place on the fitting 4I and cap 4 respectively. The cover 49 may be of thin resilient rubber or other material which will stretch and fit tightly over the rigid outer element of the cap and hold itself in place thereon.
When the described principal unit of apparatus has been sterilized, it may be handled to the extent necessary for packaging purposes without danger of. contaminating any of the internal or vital external surfaces of the apparatus so that the packaged unit may be delivered in effectively sterilized condition to the user of the'apparatus.
One convenient method of packaging the apparatus is to provide a paperboard loop or receptacle 58 (Fig. 3) formed from a lblank such as` wall 54 is formed by abutting end portions of the main panel 5I. The auxiliary panel 52 is folded inwardly from the bottom edge of the side wall 55 to form a partial bottom for the loop, and the panel 53 is folded upwardly and secured to thel `abutting end portions which form the side wall 54.
The panel 52 has foldably connected to it an end extension 58 which is folded upwardly from the end of the bottom forming portion 52, and said extension 58 has a fiap 58 foldably connected to one of its sides, said flap 59 being folded to and secured in overlapping'position on the inside of the panel 53. The extension 58 forms a partition in the loop member 50 to provide an end space or chamber 88 which is adapted to house the main cap structure 4 with its protective cap 48 thereon. Said partition member 58 is suitably notched as indicated at 6I and 62 to receive the lter tube element 33 in place on the fitting I8 and the sight tube 31, the upper portion 8| of the notch in said partition being of such width as to receive therein the diameter of a. lip-like circumferential flange I2a which projects from the cap element 8 in slightly spaced relation to the nozzle I4 as best shown in Figs. 1 and 2. 'The notch portion 52 in said partition is of such width as toreceive the diameter' of the boss I1 which receives the fitting I8.
The filter member 33 and the sight tube 31 carried by the cap structure, will project into the main portion of the receptacle formedfby the loop 58 and the tube 38 is bent reversely and extended outwardly through a slot 55a in the side wall v5 as indicated at 83. The tube 38 is then wrapped a few turns (according to its length) close fit in its passage through the slot 55a of the side wall o f the loop.
The paperboard loop with the apparatus packaged therein and thereon may next be enclosed in any suitable outer container 83 of paperboard or other material as represented in Fig. 7. Said outer container will preferably be provided with vscoring such as represented at 84 for facilitating opening of the package to permit the removal of the loop 58 with its content. In this instance, the container 83 is illustrated as having its top wall scored for aording a full opening to the interior thereof. However, either of the other walls of the container may be similarlyprovided with means for opening of the container. The outer containershould, however, be of such size that the tubing 38 wrapped around the outside of the loop 58 will fit snugly within the container so as to permit shifting of the packaged material within the outer container. Although it is not essential, it is desirable that the outer container be of sufficient rigidity to prevent collapsing of the tubing 38 between the walls of the outer container and the walls of the loop 58. l
By packaging the apparatus in the described manner. the parts are held in fixed position with the tubing so arranged that it is free of sharp bends or kinks. Certain kinds of tubing tend to set in any position in which it is held for an extended period. By supporting the apparatus in the manner explained, the formation of objectionable bends or kinks, either initially or because of shifting of the parts in the package, is prevented.
Auxiliary equipment such as the cap 4a with its means for delivering liquid from one bottle to another, and an air filter may be sterilized, protected and packaged in a manner similar to that illustrated in Figs. 3 to '1, inclusive.
The tube 38 is preferably of a synthetic plastic composition of a kind now available on the market and which is sufllciently transparent to permit visual inspection of the ow of liquid through the tube, effectively resistant to chemical action by any of the liquids which would ordinarily be conducted therein in connection with intravenous or like injections, flexible and resilient with the capacity of withstanding heat sterilization in an autoclave without too seriously impairing its resiliency characteristic which is relied upon for holding the tube end on the sight tube 31 and on the `needle element 45, and it is smooth surfaced inside and out, and is produced with a high degree of uniformity in respect of its internal and external diameters so that a selected size of tubing will practically always fit with the same degree of tightness on other parts of a specified size. The
resiliency of thematerial is also such that the tube will automatically expand when the ilow controlling device 43 is adjusted from a closed position to an open position, even after the tube has been subjected to sterilizing treatment. Tublng of this character is considerably less expensive than the equivalent rubber tubing which has most commonly been used in connection with venoclysis sets. The metal fittings such as 48 and 4I are of simple character and construction so that they are of low cost, and the glass sight tube 31 and the parts of the cap 4 are also of such low cost that all oi these parts may .be disposed of after they have been used once without adding excessively to the cost of af'biood transfusion or the administration of liquid by means of this type of apparatus. Disposal of the equipment after use eliminates the conventional practice of resterilizing the equipment with the attendant uncertainties as to thoroughness oi' the sterilization and in this respect any slight increase in the cost of employing disposable equipment such as'here described is fully justified, in that any danger of infecting the patient by reason of inadequately sterilized equipment is eliminated.
Th'e outer shell oi the cap 4 never comes into direct contact with any of the liquid being administered. If desired, said outer cap element may be preserved ands'terilized as a safety measure and re-assembled with a new inner member 9. This practice, however, would involve extra handling of the sterilized member 9 which would probably be somewhat objectionable because of the danger of contaminating the same. The metal fitting I8 and the glass sight tube 31 maybe separated from the other parts if desired and re-sterllized for reuse. sterilization of these parts being readily aecomplished without any questions Aas to the sumciency of the sterilizing operation. However, for the reasons already indicated in respect of the necessity of handling the parts for assembling with other elements, it is preferable that all of these parts be disposed after a single use so as to obtain the greatest benefits of certainty of complete sterilization of new equipment.
Various other arrangements for packaging the apparatus may, of course, be employed, and various changes may be made in the structure Without departing from the invention.
