H. A, PRINGLE ASEPTIC PACK Deoa 3, 1935.

Filed Oct. ll, 1934 Dz ven oz ward.Prngle .B l y .Httoflgu Patented Dec. 3, 1935 UNITED STATES PATENT OFFIQE 13 Claims.

This invention relates to improvements in ,aseptic packs comprising hypodermic syringe outfits for certain treatments notably for such as usually must of necessity be self administered.

.5 The utility of such packs may be most readily appreciated by consideration of the circumstances attendant such self treatments and the essential sterile condition of the instruments which must be maintained. Those suiering from such diseases as diabetes are dependent upon insulin injections at regular intervals, andwhile the patient eventually acquires a certain degree of skill and care, there is always present the possibility that some precaution against infection has been overlooked.

My invention provides a complete outt including, beside the hypodermic syringe, a swab and a supply of alcohol, and spare needles coniined in liquid tight compartments in which the sterile condition of the instruments is ensured. For this outfit I provide a pack which may be conveniently carried as in a pocket without the danger of leakage or breakage, and which while invaluble to patients and doctors alike because of its4 aseptic condition, is also of great use because the pack may beset upright and the instruments contained therein be supported .as by a rack or stand, thus not only facilitating treatments, but also further ensuring the sterility of the instruments.

While I have suggested the use of my invention las practised by those who rely on self treatment and who, therefore, may be assumed to have a degree of skill commensurate with their experience, it will be readily appreciated that my pack will be even more invaluble to those unskilled persons who will require such treatments in the future and to those who are clumsy or nervously inclined.

4 In the drawing I have shown and in the specification described a simple embodiment of my invention.

In the drawing:

Fig. 1 is an elevation of my pack.

Fig. 2 is a sectional elevation showing the instruments supported within the several tubes, and

Fig. 3 is a View along the lines 3-3 of Fig. 1 showing a slightly modified form.

My pack consists o1 three tubes l, 2, and 3 which are held in alignment by the clamp members 4 and 5 which rigidly hold the tubes I and 3. The tube 2 is provided with an annular recess 6 into which a protuberance 'l on the clamp member 4 ts so that while the tube 2 may be freely rotated its axial movement is extremely limited.

As shown in Fig. 3 the clamp members 4 and 5 may be detachably united as by the screws 8 to permit the tubes to be used and cleansed` separately if desired.

The tube 2 has secured to its lower end as at lI5 3 a resilient supporting piece ID having flat lateral feet Ita. When my pack is to be carried either by the clip I I or in a leather envelope, the feet IIEa overlie the ends of the' tubes I and 2 and are held in that position by the protuberance 1 10 bearing against the lower edge of the annular recess 6 in the tube 2.

When any of the instruments are to be used, the tube 2 and the feet Illa are pivoted to provide for adequate support so that the pack may 15 be used as a stand. The slight axial movement of the tube 2 frees the feet Illa so that they may lie in the same plane as the bases of the tubes I and 3.

A hypodermic syringe I2 is suspended in the 20 liquid tight tube 3. The linger rest or shoulder I2a of the syringe I2 overlies a rubber washer I3 positioned in the annular recess Ill in the upper end of the tube 3 which is enlarged to receive the detachable cap I5. The cap l5 has an in- 25 ternal shoulder I6 which is adapted to bear against the shoulder I2a of the syringe I2 to lock it against its rubber cushion I3. A detachable bottom 3fL is preferably provided to facilitate sterilization. 30

The tube 2 is also liquid tight and is adapted to conne the spear-head swab Il which is attached to the cap 2a from the tube 2. A gasket I8 prevents leakage as this tube is adapted to serve as an alcohol reservoir. The tube I is 35 desired to protect spare needles I9 which are held in aligned spaced position by the split sleeve 20.

The detachable caps may be secured to their respective tubes in any desired way, and the support for the tub-es when my pack is to be used 40 as a stand may be variously formed, or the pack may be so formed as to permit any one of the tubes, as tube I for the spare needles, to be pivoted to supporting position.

With such an aseptic pack, a patient is able 45.

to carry a complete outfit with him. He needs only to sterilize the complete pack and contents by boiling at regular intervals. With such a pack, self treatment is made easier for the patient, not only because of the ensured sterility, v but also because of the accessibility of the instruments when supported as in a sterile stand. Various modifications in the construction and assembly of my device as well as the materials used may obviously be resorted to without departing from the spirit of my invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A hypodermic pack unit for pocket or like transportation comprising a plurality of containers, means holding said containers in alignment and permitting one of said containers to be freely rotated and to have slight aXial movement, and a support carried by said rotatable container adapted to lie in alignment with said containers and to be pivoted to support said containers in an upright position.

2. A hypodermic pack unit for pocket or like transportation comprising a plurality of containers, members holding said containers in alignment and permitting one of said containers to be freely rotated and to have slight axial movement, a support carried by said rotatable container adapted to lie in alignment with said containers and to be pivoted to support said containers in an upright position, one of said containers having an annular recess and one of said members having a protuberance adapted to enter said recess, said protuberance and said recess being so shaped as to permit free rotation and limited axial movement of said container.

3. A hypodermic syringe outfit comprising a triplet of containers, means holding said containers in alignment and spacing the same from each other and comprising a clamp, the outer two of said containers being rigidly held in said clamp and the middle container being rotatable therein, and a support for said containers secured to said middle container.

4. A hypodermic syringe outt comprising a plurality of containers, a clamp holding said containers in spaced alignment, one of said containers being rotatable in said clamp and including a support adapted on predetermined rotation of said container to hold said outfit in balanced erect position.

5. A hypodermic syringe outfit comprising a plurality of containers, a clamp holding said containers in spaced alignment, one of said containers being rotatable in said clamp and including a support adapted on predetermined rotation of said container to hold said outt in balanced erect position, and means limiting axial movement of said rotatable container.

6. A hypodermic syringe outt comprising a plurality of spaced aligned containers, one of said containers comprising a tube having an enlarged upper portion providing a shoulder, a cover for said tube having a shoulder, and a syringe comprising a ilanged barrel, a washer on said barrel beneath said flange, said flange and washer being adapted to be compressibly held between the shoulder on the tube and the shoulder on the cover, and a pivoted support for said container.
