These syringes nec essarily have been of rugged construction to withstand repeated usage and consequently have been relatively expensive. Some efforts have been made to provide a douche syringe which is sufficiently economical that it could be discharged after a single use. However, these prior disposable syringes have not been satisfactory since they have been difficult to fill with liquid, have been difficult to seal'after being filled, and have not provided simple valve means to prevent the discharge of liquid therefrom until desired. Some examples of prior art structures are the Patents to Kempel, No. 2,664,891, Hyatt, No. 2,811,968and McKenna No. 3,057,352.
SUMMARY OF THE INVENTION The present invention is a disposable syringe including a bladder having a discharge nozzle at one end and a filler neck at the other end aroundwhich elongated flexible material is provided to maintain the neck open while filling the bladder but which can be collapsed to secure the neck in closed sealing position. Aportion of the elongated flexible material is attached to the tiller neck and another portion remains unattached and extends away from the tiller neck to provide a free end for usein sealing the tiller neck in closed position.
It is an object of the invention to provide a disposable syringe including a bladder having a flexible openended neck at one end and a discharge nozzle at the other end and in which the flexible neck has elongated members mounted thereon in a manner to retain the neck in open position during filling but which can be BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective illustrating the disposable syringe.

DESCRIPTION or THE PREFERRED EMBODIMENT With reference to the drawings, a syringe device 20 is provided having a flexible bag or bladder 21 which is relatively wide at the middle 22 and has relatively narrower upper and lower elongated end sections 23 and 24, respectively. The bladder 21 is constructed of two sheets of flexible thermoplastic material such as acrylics, cellulose acetate, cellulose acetate butyrate, vinyl polymers and copolymers, polyethylene and the like which are heat sealed along side seams 25.
At the upper end 23 of the bladder, the side seams converge to form an elongated tiller'neck 26 which is open at the top. end for reception of liquid. The convergent side seams terminate below the end of the plastic sheet material thereby forming a pair of 'flap's 27. Such flaps are folded over and attached along their bottom edges to the outside of the bladder in any desired manner, as by an adhesive 28 to form a rim or pocket around the top of the elongated neck 26. The side edges of the flaps adjacent the side seams 25 are not joined to the bladder and thus the pocket formed by the flaps is open at opposite ends for a purpose to be described below. I
At the elongated lower end section 24 of the bladder,
the side seams converge to form an outlet sleeve 30 which receives the upper end of a tubular discharge nozzle 31 having a longitudinally extending passageway or bore 32 through which fluid in the syringe 20 may be discharged. The discharge nozzle 31 is constructed of any desired semi-flexible material and has relatively thick walls of sufficient rigidity to maintain the passageway 32 open when the nozzle is inserted into the human body or otherwise appropriately used.
i The outlet sleeve 30 is secured to one end of the nozzle 31 by any suitable means, such as an elastic member 33, which resiliently clamps a portion of the outlet sleeve into a transverse annular groove 34 formed in the outer surface of the nozzle adjacent to the upper end. Although generally the nozzle 31 is removably mounted within the outlet sleeve 30, it is contemplated that in some cases the nozzle may be permanently fixed within the outlet sleeve by adhesive or other suitable means.
With reference to FIGS. 1, 3 and 4, it may be desirable to add a medicament to the liquid within the bladder 21 and this can be done by mixing the medicine directly with the liquid either before or after the liquid is introduced into the bladder. However, to insure that a correct amount of medicament is added to the liquid,
a container or pouch 35 having a prescribed quantity of medicament 36 is attached to the inner wall of the bladder 21. The pouch 35 may be constructed of an easily rupturable material or it-may be constructed of a gelatinous material which will dissolve in the presence of a liquid. When the liquidis introduced into the bladder the medicament is mixed with the liquid to provide a desired solution.
As illustrated best in FIGS. 2 and 9-13 the upper end of the nozzle 31 is provided with a portion 37 of reduced wall thickness, while the diameter of the passageway 32 remains substantially constant. Due to the reduced thickness, the portion 37 is substantially more flexible than the remainder of the nozzle 31 and is adapted to be compressed so as to close the upper end of the passage 32. In order to compress the reduced portion and to maintain the same in compressed condition, a clamp 40 is provided having a base 41 of generally rectangular configuration with upstanding ears 42 and 43 at opposite ends thereof. The ears 42 and 43 may extend outwardly substantially at right angles to the base 41, or, as illustrated, the ear 42 may be curved or angled inwardly. Each of the ears has an opening 44 in which a pin 45 having a head 46 is received Preferably, the pin is inserted through the ear 42 so that a portion of the head 46 engages such ear and the remainder of the head is spaced from the ear to provide for ready grasping of the head when the pin is to be removed.
As illustrated in FIGS. 9-11, the base 41 is placed in engagement with the reduced portion 37 of the nozzle and the overlying portion of the outlet sleeve 30 of the bladder. Then the nozzle end portion is collapsed or compressed and the pin 45 is inserted through the openings 44 to retain the nozzle end portion in collapsed condition and prevent the passage of liquid therethrough. It is noted that the clamp 40 be applied only to the outlet sleeve 30 to prevent the discharge of liquid from the bladder.
With reference to FIGS. -8 the upper or open end of the neck 26 is provided with a pair of tie strips 47 which are carried within the pockets formed by the flaps 27. Each of these strips includes a thin wire or other stiff material sandwiched between two narrow lengths of paper, plastic or other flexible material. When the ties are to be inserted into the pockets at the top of the neck 26, each of such ties is bent into a J- shape having a short leg of a length substantially equal to the width of the neck and a long leg approximately twice as long'as the short leg. When the strips are inserted into the pockets, the long leg is passed through one of the pockets and the short leg is received within the other pocket in such a manner that the bight portion abuts the side seams 25 and provides a reinforcement therefor. The strips are arranged so that one leg extends from one side of the neck and the other long leg extends from the other side of the neck so that both side seams will be reinforced and the short leg of one strip will be disposed within the same pocket as the long leg of the other strip.
When it is desired to introduce liquid into the bladder 21, the open end of the neck 26 is spread apart in the strips are generally parallel with each other, after which the upper end of the neck .is rolled upon itself to close the upper end of the bladder. Thereafter the free ends of the long legs are bent toward each other and twisted together to seal the neck.
The syringe 20 together with the clamp 40 may be folded to form a small compact unit which is stored in a suitable small container, for example, like a hard pack cigarette package (not shown). In certain cases when the nozzle 31 is detachable from the bladder 21, it is contemplated that the nozzle could be packaged in a separate container. Also,.if desired, several bladders could be packaged together with a single nozzle.
In the operation of the device, the passageway 32 is first closed by the clamp 40, the open end of the neck 26 is spread apart and remains in the open position due to the added rigidity provided by strips 47. The medicamentpouch 35 is ruptured and discharges its contents into the bladder. A suitable quantity of liquid is introduced through the elongated neck 26 and then the neck is rolled upon itself and locked into a closed position by twisting the free ends of strips 47 together. Thereafter, the nozzle 16 is inserted into the human body, and the pin 45 is removed to permit discharge of the liquid contents of the bladder through passageway 32 of the nozzle. Pressure may be applied to the bladder to discharge the liquid from the bladder with suitable force. When such pressure is applied to the bladder, liquid is prevented from leaking through the closed neck 26 or around the joint between the outlet sleeve 30 and the nozzle 31.
