Definitions
- gh in sealing relaer is formed with a g an injection needle in alignment in use with the inner tubular member.
- PATENTEU JANZBIQYI SHEET 2 OF 2 DISPOSABLE SYRINGE This invention relates to a device for the administration of parenteral solutions and more particularly to a hypodermic syringe adapted to contain dry solids separate and apart from the dissolving or carrier liquids until, immediately prior to administration, the liquid is caused to flow into the compartment containing the solids for injection of the formed mixture.
- the most effective means for maintaining the shelf life over extended periods of time is to maintain complete separation between the liquid carrier and the solids to be incorporated therein, until immediately prior to use. Maintenance of solid-liquid separation until time of use presents other problems with respect to ejecting and administering the solution containing the necessary concentration of ingredients and under the most sanitary conditions.
- the usual practice is to introduce the solids into the liquid for solution in a suitable container from which the solution can be withdrawn into a syringe for injection. This procedure required the use of at least three separate containers and maintenance under sterile conditions as well as accurate measurement of the ingredients.
- FIG. 1 is a sectional elevational view of the syringe embodying the features of this invention, with the elements illustrated prior to use;
- FIG. 2 is a sectional elevational view of the syringe shown in FIG. 1 with the syringe partially actuated to effect displacement of the liquid carrier from the liquid chamber to the solids chamber for solution or admixture;
- FIG. 3 is a sectional elevational view of the syringe shown in FIGS. 1 and 2 with the syringe in fully actuated position to effect displacement of the freshly prepared solution from the solids compartment for injection;
- FIG. 4 is a sectional elevational view of a portion of the syringe shown in FIGS. 1 to 3 and showing a modification in the closure for the liquid containing compartment;
- FIG. 5 is a sectional elevational view of the actuator which may also be used as a needle cover.
- the syringe of this invention is formed with an outer casing l in the form of a tubular member, formed of glass, plastic or the like, having a continuous bore 2 extending therethrough from an open rearward end portion 3 to a neck portion 4 of smaller cross section, at the forward end.
- the forward end is sealed by means of a disc member 5 held in place in sealing relationship across the open neck 6 of the tubular member I by means of a metal cap 7 which is crimped about the outer neck end portion of the tubular member while the inner portions 8 of the cap overlap the outer edge portions of the sealing disc member overlying the flattened end surface 9 of the tubular member.
- a hub member II has a skirt portion I2 crimped about the skirt portion of the cap for securing the hub onto the neck end portion of the tubular member.
- the hub is also formed with an intermediate collapsible or corrugated portion 13 extending forwardly in axial alignment with the forward end of the tubular member with a hub 14 on the forward end through which a hollow needle 15 extends with a sharpened end portion of the needle projecting into the interior of the hub member II for a distance less than the spaced relationship between the hub end and the diaphragm 5, when in normal position, thereby to locate the rearward end of the needle immediately in advance of the center of the diaphragm.
- a second tubular member 20 of glass, plastic or the like material is dimensioned to have an outer wall to wall dimension which is less than the inner wall to wall dimension of the tubular member I to enable the former to be telescoped through the interior of the outer tubular member 1.
- the second tubular member is similarly formed with a passage 21 extending from the open rearward end 22 through a neck portion 23 of smaller cross section at the forward end.
- the forward neck end portion of the second tubular member is fitted with a rubber stopper 24 including an outer ribbed portion 25 fitted in gripping relationship about the neck and extending laterally beyond the walls of the second tubular member for a distance to effect sealing engagement with the inner walls of the outer tubular member 1 whereby the second tubular member is capable of the function of a piston movable axially relative the outer tubular member 1 thereby to provide a piston and cylinder arrangement between the two tubular members.
- the rubber stopper 25 has a disc portion 26 which normally spans the forward end of the passage to seal the tubular member. It is further formed with one or more openings 27 in the lateral portions beyond the passage to enable flow of liquid from the second tubular member into the firstwhen the sealing disc 26 is flexed for displacement for sealing engagement with the end of the second tubular member. Again, the rearward end portion of the second tubular member is formed with an outwardly extending flanged portion 28 for use as a finger grip, as will hereinafter be described. The rearward end of the passage 21 is sealed with a rubber plug 30 mounted for axial displacement through the passage 21 as a piston within the cylinder defined by the second tubular member.
- Means such as a threaded stud 31, is provided on the rearward end of the plug type piston for connection of an actuator 32 for displacement of the piston relative the cylinder.
- the actuator 32 is in the form of a third elongate tubular member dimensioned to have a cross section less than the cross section of the passage 21 through the second tubular member and formed at one end with an internally threaded female portion 33 for threaded engagement onto the threaded plug 31.
- the rearward end of the actuator is formed with an outwardly extending flanged portion 34, for use as a finger grip.
- the actuator is capable of use as a needle cover to protect the needle when other than in position of use and which can be removed from the hub to expose the needle and for attachment to the plug for operation of the device, when in position of use.
- the element supplies the dual function of a needle protector during nonuse and as an actuator in use.
- fluid 35 is housed in sealing relationship within the second tubular member while the dry medicant is housed in sealing relationship within the first tubular member.
- the loaded device can be shipped and stored for extended periods of time without deterioration of the ingredients and without exposure of the elements to nonsanitary conditions.
- Administration is made without change of devices and without exposure of the freshly prepared solution or suspension by inserting the needle into the vessel or tissue.
- the outer casing is grasped with the one hand with the needle fingers beneath the flanged portion 10.
- the needle is inserted and the hub is compressed to effect relative movement between the needle and the rubber sealing diaphragm 5 whereby the rearward end of the needle punctures the diaphragm to bring the end of the needle into the chamber 2 for direct communication with the freshly prepared liquid system.
- the thumb is pressed down onto the actuator which, at the end of its travel in the second tubular member, causes displacement of the second tubular member for movement as a piston through the cylindrical passage 2 of the first tubular member thereby forcibly to displace the freshly prepared liquid system from the interior of the first tubular member through the needle and into the tissue.
- the entire device can be discarded.
- the sealing disc 26 extends continuously in sealing engagement across the neck of the second tubular member but is provided with a slit 40 which maintains a sealing relationship until opened in response to the application of fluid pressure as the plug 30 is displaced forwardly through the passage 21.
- a syringe assembly for injection comprising inner and outer tubular members with the inner members having an outer wall to wall dimension less than the inner wall to wall dimension of the outer tubular member to enable the inner tubular member to be telescoped within the outer tubular member, said inner tubular member defining a planar flange surface on the forward end thereof, a rupturable closure sealing the forward end of the outer tubular member, a.flexible closure having a resilient, thin web means across said flange surface and sealing the forward end of the inner tubular member, said thin web means including passage means therethrough seated on said flange surface in sealing relation thereto whereby said passage means are unseated to communicate with the interior of the inner tubular member in response to internal pressure therein, a piston ring portion on the forward end of the inner tubular member in sliding engagement with the inner walls of the outer tubular member.
- a piston plug dimensioned slidably to be received within the inner tubular member, and means for actuating the piston plug axially relative to the inner tubular member, a hypodermic needle, and collapsible means on the forward end ortion of the outer tubular member supporting the needle wit the rear ward end terminating a short distance in advance of the rupturable closure when in uncollapsed position and penetrating through the rupturable closure when in collapsed position.
- a syringe as claimed in claim 1 which includes a removable cover for the needle.
- a syringe as claimed in claim 1 in which the inner tubular member is adapted to contain a liquid carrier and in which the outer tubular member is adapted to contain a dry material to be taken up by the liquid carrier when the latter is forced from the inner tubular member into the outer tubular member in response to movement of the piston plug axially in the inner tubular member.
- a syringe as claimed in claim 1 in which the collapsible means comprises a hub member secured at its rearward end portion onto the forward end of the outer tubular member and a forward end having an opening through which the needle extends with a flexible portion between the ends to enable displacement of the forward end between normal and collapsed position.
- a syringe as claimed in claim 1 in which the piston ring portion on the forward end of the inner tubular member comprises ring members of rubberlike material in sealing engagement with the outer walls of the inner tubular member and extending into sealing engagement with the inner walls of the outer tubular member.
- a syringe as claimed in claim 1 in which the piston ring portion and flexible closure are of a unitary construction mounted onto the forward end portion of the inner tubular member and in which the means in the flexible sealing closure comprises openings extending through the sealing member in a position offset outwardly from axial alignment with the passage through the inner tubular member.
- a syringe as claimed in claim 1 which includes means on the rearward end of the piston plug for attachment of an actuator and which includes an elongate actuator dimensioned to exceed the length of travel of the piston plug through the inner tubular member.
- a syringe as claimed in claim 8 in which the actuator comprises an elongate rod dimensioned to be received in telescoping relation within the inner tubular member and with means for attachment of the actuator to the piston plug.
