COMBINATION PRE sTERlLlzED SYRINGE AND CONTAINER April 17, 1956 Original Filed March 19, 1953 INVENTOR M/CHAE L L /PAR/ ATTORNEY United States Patent COMBINATION PRE-STERILIZED SYRINGE AND CONTAINER Michael Lipari, Oneonta, N. Y., assignor to Giaocchino Lipari, East Meadow, N. Y

Original application March 19, 1953, Serial No. 343,323. Divided and this application October 13, 1954, Serial No. 461,963 r 11 Claims. c ne-21s This invention relates to surgery and more particularly to a device in the nature of a hypodermic syringe which may be pre-sterilized and utilized to obtain a specimen of body or other fluids, such as blood, and thereafter provide a container for such fluid for storing or transporting the same for laboratory examination. This application is a division of my copending application Serial No. 343,323,,

in Public Health work, and furthermore, the speed with which such examinations might be conducted was seriously impaired by the necessity for first obtaining the specimen and then transferring the same from the syringe to a sterile container. While numerous attempts have been made in the past to provide a combined syringe and container, or to provide a syringe which could be conveniently pre-sterilized and packaged prior to use, nevertheless, these prior art devices have not proven entirely satisfactory and their use has been relatively infrequent.

It is accordingly an object of this invention to provide a combination pre-sterilized syringe and container in which the syringe as well as the needle utilized therewith, may be provided as a unitary package and the entire device protected against contamination. I

A further object of the invention is the provision of a combination pre-sterilized syringe and container consisting of a unitary package including the needle, and also including a shield for such needle which may be utilized to move such needle from operative to inoperative position, the shield thereafter being removed and discarded.

A still further object of the invention is the provision of a combination pie-sterilized syringe and container in which the plunger of the syringe, after being utiiized to withdraw fluid from the body or other source into the syringe, is utilized to close such syringe thereby providing a storage or shipping container.

Another object of the invention is the provision of a combination pro-sterilized syringe and container which includes a readily available supply of sterilized swab material which may be conveniently utilized to cleanse the skin surface to be pierced by the needle and to cover the wound formed by the needle in the body of the patient.

A further object of the invention is the provision of a combination pre-sterilized syringe and container in which a specimen of fluid may be drawn into the syringe by outward movement of an actuating member attached to the plunger of the syringe after which such actuating member may be removed and the needle also removed from the syringe thereby providing a container for storing or transporting the specimen containedtherein.

A still further objectof the invention is the provision 2,742,041 Patented Apr. 17, 1956 ice of a combination pre-sterilized syringe and container which may be readily and economically manufactured from suitable materials at a sufiiciently low cost to be expendable after a single use. i

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing wherein;

Figure l, is a longitudinal sectional view showing a combination syringe and container constructed in accordance with this invention and with the needle in inoperative position;

Fig. 2, a view similar to Fig. 1, but showing the needle in operative position and with the needle shield removed; Y

Fig. 3, an elevational view with parts in section for greater clarity, and showing the combination syringe and container of this invention in use; i

Fig. 4, a sectional view on the line 4--4 of Fig. 1; and

Fig. 5, a sectional view on the line 55 of Fig, 1.

With continued reference to the drawing there is shown a combination syringe and container constructed in accordance with this invention and which may well comprise a body providing an elongated cylinder 11, and, of course, the body 10 may be of any desiredexternal configuration. The cylinder 11 is open at one end and closed at the other by a wall 12. Centrally of the Wall 12 there is provided an aperture 13 and depending from the wall 12 is an annular skirt 14 which provides an outwardly opening recess 15; Disposed within the recess 15 and tightly engaging the walls thereof, is a plug 16 of yieldable material, such as rubber or the like, and this plug 16 is provided with an outwardly opening tapered recess 17, the purposeof which will presently appear.

Slidably disposed in the cylinder 11 is aplunger' 18 which may be formed of any suitable material and "centrally of the upper surface thereof there is provided a threaded recess 19 for thrcadedly and detachably receiving a threaded stud 20 forming a part of and depending from an actuating member 21; Actuating member 21is provided with a plurality of elongated ribs 22 which may be in the form of a cross, as shown, or any other desired configuration, and these ribs 22 have an outer diameter slightly less than the diameter of the cylinder-11. Thus the ribs 22 may engage the wall of cylinder 11 an'd'act as guides to maintain the actuating member 21 in substantially axial alignment with the cylinder 11. The ac tuating member 21 terminates at its upper end in a finger-engaging stopper 23 provided with a tapered portion 24 for tightly engaging in the outer end of cylinder 11 and also being provided with an annular flange 25 having a diameter somewhat greater'than the outer diameter of body 10 and providing a portion which may be easily gripped by the fingers of the operator or technician utilizing this device. The stopper 24 is provided with an outwardly opening recess 26' which may serve to receive and contain a quantity of sterile swab material 27, and this materialmay beretainedina sterile condition by means of a seal 28 of suitable material which extends over the recess 26 and engages the annular flange .25. If desired, the seal 28 may, of course, extend downwardly and engage the outer wall of the body 10 to provide an additional seal between the-stopper 2.3 and the body 10 thereby further insuring against contamination of the cylinder 11. Y r

Slidably mounted on the skirt 14 is a needle shield 29 which may well comprise an elongated cylindrical member closed at one end by a wall 30, and having an internal diameter sufficient to providea relatively tight sliding fit on the outer surface of skirt 14. Spaced inwardly of the shield 29 from the open end thereof, is a partition 31 which is provided with a central aperture 32. Secured to the wall 30 of the shield 29 and extending upsurface of partition 31 with the sharpened end 35 of the needle 34 spaced from the end wall of the shield 29 and with the shield and needle in the position shown in Fig. l, the sharpened end 36 of the needle 34 penetrates a relatively short distance into the plug 16.

The body 10, actuating member 21, and needle shield .29 may be formed of glass or a non-breakable plastic,

or any other suitable material which will withstand a sterilizing temperature, and it is to be presumed, that the entire device will be presterilized and provided as a unitary package with the parts in relationship shown in Fig. 1. If desired, a seal of suitable material may be provided between the needle shield 29 and the skirt 14, but normally the engagement between the shield 29 and skirt 14 is sufficiently tight to preclude the necessity of a seal in this location.

In order to prepare the device of this invention for use, it is only necessary to force the needle shield 29 inwardly on the skirt 14, which, by reason of the engagement of partition 31 with the collar 37, will force the sharpened end 36 of the needle 34 through the plug 16 and into communication with the cylinder 11 through the aperture 13 in the end wall 12. At the same time, the collar 37 will be moved into the recess 17 until the complementary wall theretof, tightly engage, as clearly shown in Fig. 2. At this time, the shield 29 may be removed by simply withdrawing the same in an axial direction which will,

of course, remove the stylet 33 from the interior of the needle 34, leaving the sharpened end 35 available for use. The sharpened end 35 of the needle 34 may then be inserted in the arm 39, or other body part of a patient,

or into a vessel form which a sample of fluid is to be taken and the plunger 18 withdrawn outwardly of the cylinder 11 by grasping the flange 25 on the stopper 24 of the actuating member 21. This operation is clearly shown in Fig. 3, and by reason of the movement of the plunger 18, fluid will be drawn into the cylinder 11 through the needle 34. Upon completion of the outward movement of the plunger 18, after a suflicient quantity of fluid has been drawn into the cylinder 11, the actuating member 21 may be removed from the plunger 13 by relative rotation which will release the threaded engagement between the stud 20 and the recess 19 in the plunger 18, and thereafter plunger 18 serves as an air-tight closure for the cylinder 11. The needle 34 and the collar 37 may be removed from the plug 16 and the yieldability of the material forming such plug results in closing the opening formed by the needle therein, which in turn seals the cylinder'll and prevents contamination of the contents thereof. The swab material 27 may be conveniently removed from the recess 26 by removing the seal 28 and such swab material utilized to cleanse the skin surface to be pierced by the needle 24 and to cover the wound formed by the needle in the body of the patient. I

The body 10 containing the fluid 40 and closed at one end by the plunger 18 and then at the opposite end by the plug 16, provides a container for the fluid 20 which may be utilized for storing the same or transportation to a laboratory for examination, and obviously, there is no opportunity for contamination of the contents thereof prior to such laboratory examination. Upon completion of such examination, the body 10 may, if desired, be discarded or sterilized and reassembled for future use.

The ribs 22 in engagement with the interior surface of the cylinder 11 serve to guide the actuating member 21 and plunger 18 during outward movement thereof, thereby preventing any displacement of the plunger 18 which might result in leakage between such plunger and the wall of the cylinder 11. Likewise, the provision of the sterile swab material 27 makes it unnecessary to provide any other equipment than that contained in the unitary package provided by the combined syringe and container of this invention.

It will therefore be seen, that by this invention there has been provided an extremely economical, yet highly eflicient combination syringe and container which may be conveniently pre-sterilized and provided with means for conveniently attaching a needle in operative position, after which a specimen may be obtained and the device conveniently closed to provide a sterile container for such SECCliTiCil. The device of this invention is particularly well adapted to obtain specimens of body fluids during mass examinations and is of such economical construction that the same may be utilized once and then discarded or, of course, the same, if desired, may be sterilized and reused.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawing and described in the specification, but only as indicated in the appended claims.
