Self Injectable, Pre-Filled Syringes, Vials and Combinations Thereof

Abstract

A syringe for injecting liquid medicine into a body, having its needle inside said syringe liquid holding barrel, pointed at one end of the syringe barrel which rests on user's skin when injecting, which end is sealed to hold the liquid inside the barrel of said syringe by a rubber like seal, through which seal said needle's sharp tip can exit when the needle is pressed towards the body via the other end of the barrel, which needle has conduit(s) near the other end of the needle to let said liquid into the inner tube of the needle to exit via said tip when the liquid is pressured as the needle is pushed into the user's body, which syringe can be prefilled during manufacturing, so that the syringe acts as a vial too, enabling self administration upon unpacking.

Claims

1. A syringe, including a barrel with an opening at one end and a liquid outlet at its other end, wherein, in pre injection mode: said barrel contains a lid, at least part of said lid is within said barrel's interior, the entirety of said lid's circumference is tangential to the inner surface of said barrel, tightly enough to resist leaking of any liquid out of the barrel from around said circumference, said lid is slidable along the interior of said barrel, between said barrel's opening and outlet, said lid harbours a syringe needle, which shaft is extended off the lid, inside said barrel, the sharp tip, a.k.a bevel of which needle is pointed towards said barrel's outlet, said needle's end, other than tip, called the base here, is firmly attached to said lid, said lid has means to secure the needle's base and maintain its tip towards said outlet, said needle has a liquid inlet at a segment of the needle called waist here, positioned substantially close to said base, allowing the liquid from the barrel into the needles core tube, said barrel's liquid outlet is blocked by a seal to prevent liquid escaping the barrel, and in addition to all above, said seal is penetrable by the needle's tip, thus, when said lid is pressed into the barrel, as the exterior of the barrels outlet end is resting on a patient's body, said needle's tip pierces said seal, then the patient's skin, while said liquid is pushed via said needle's inlet, through the needle's hollow core to needle's tip and released inside said body, whereby numerous advantages over conventional syringes are achieved, some being: said lid can be pushed towards the barrel outlet using a finger or rod, as a plunger's handle, the syringe can be self administered, no skill needed to hold the needle at proper distance from and angle with a patient's skin, the needle is held by both said lid and seal, before being pushed into the user's body, providing more stability and less chance of bending of needle before and after entering the body, liquid is dispersed along all of needle's travel inside the body, providing much better absorption, compared to conventional release at the end point of needle's travel, the needle, is not visible by the patient, easing anxiety, no chance of the needle being accidently touched or damaged before administered, the needle is protected by the barrel and needs no protection by costlier packaging, the syringe is much shorter for less packaging volume and material, and many other advantages.

2. Syringe of claim 1 wherein said lid has a handle extending towards barrel's opening, whereby the handle aids maneuvering said lid.

3. Syringe of claim 1 wherein said lid has a handle extending towards barrel's opening, which handle is disjoint from said lid, whereby one handle can serve more than just one syringe.

4. Syringe of claim 1 wherein said lid has a handle extending towards barrel's opening, which handle is disjoint from said lid, said handle and lid have means for latching to each other, whereby said handle can be used to pull the lid away from the barrel's outlet, whereby the syringe can be pulled back into the barrel, for safety and to enable filling and refilling the barrel via the needle.

5. Syringe of claim 1 wherein said lid has a handle extended towards barrel's opening, which handle is disjoint from said lid, said handle and lid have means of latching to each other by screwing one into the other, whereby said handle can be used to pull the lid away from the barrel's outlet, whereby the syringe can be pulled back into the barrel, for safety and to enable filling and refilling the barrel via the needle.

6. Syringe of claim 1 wherein said lid has means for pulling it away from barrels outlet, whereby the syringe can be pulled back into the barrel, for safety and to enable filling and refilling the barrel via the needle.

7. Syringe of claim 1 wherein said lid has a ring on its surface accessible form barrels opening, which ring can be used by a finger for pulling said lid away from barrels outlet, whereby the syringe can be pulled back into the barrel, for safety and to enable filling and refilling the barrel via the needle.

8. Syringe of claim 1 where said needle's tip rests inserted into said seal.

9. Syringe of claim 1 wherein a funnel is inserted into said seal, which funnel's inlet is positioned to receive said needle' tip, said funnel's outlet remaining within and sealed by said seal, pointed towards said barrel outlet, whereby the needle is guided via the funnel towards the outlet.

10. Syringe of claim 1 wherein the mechanism of attaching said needle's base to said lid has means to enable replacing the needle.

11. Syringe of claim 1 wherein any layer of said lid which cannot be penetrated by a needle has at least one hole through which the needle of another syringe can be inserted into the barrel, whereby the barrel can be filled, emptied and de-aired.

12. Syringe of claim 1 wherein any layer of said lid which cannot be penetrated by a needle has at least one hole through which the needle of another syringe can be inserted into the barrel, the surface of said lid facing the liquid has at least one concave dip where said needle tip penetrates said surface, whereby the barrel can be maneuvered to collect any air into said dip to be de-aired by said other syringe.

13. Syringe of claim 1 wherein the surfaces of said lid and said seal that face each other are contoured for maximum mutual contact when they meet, whereby least volume of liquid can be trapped between them when said surfaces are in full surface contact.

14. Syringe of claim 1 wherein the outer surface of said barrel facing a patient's skin when injecting is concave, whereby resting it on the skin and holding it at a desired angle is eased.

15. Syringe of claim 1 wherein the outer surface of said barrel facing a patient's skin when injecting is overall concave with a number of planar surfaces, whereby resting said one of the surfaces on the skin and holding it steady at an angle determined by said surface is eased.

16. Syringe of claim 1 wherein said barrel is prefilled and de-aired, ready to inject, whereby much time, skill, liquid waste, inaccuracies and risks of onsite filling and de-airing is saved, enabling buying from a local shop and self injection by even a child.

17. Syringe of claim 1 wherein said needle has its own means of plunging it into a patient's body, as said lid remains unmoved, to be pressed to release the liquid, after the needle has entered desired depth inside a patient's body.

18. Syringe of claim 1 wherein said needle's base has a hollow core, called a well, opened at the lids surface facing the barrel's opening, into which well a rod can be inserted, via the barrel's opening, said base is slidable off the lid when pushed by said rod, said rod's exterior which remains outside of the needle's base has a diameter and shape matching those of the interior of said tunnel, sufficient to prevent liquid leakage when the rod is pushed into the barrel, whereby said needle can be inserted to desired depth into a patient's body, before said lid is pushed to release the liquid.

19. Syringe of claim 18 wherein said rod has means to latch with the needle's base, whereby the needle can be pulled back into the barrel.

20. Syringe of claim 18 wherein said rod is screwed into the well, as means to latch with the needl's base, whereby the needle can be pulled back into the barrel.

21. Syringe of claim 18 wherein said rod branches into more than one rods at the end which is out of the needle's base, said lid has a hollow core handle whose shell like body surrounds said rod, said shell via which said branches exit enough for a finger to contact and push or pull the branch, whereby the rod can be pushed into and pulled out of the barrel, while the lid plunger handle remains unmoved.

22. Syringe of claim 1 wherein at least one of said needle's base and waist are detachable from the needle and replaceable.

23. Syringe of claim 1 adapted for at least one non medical application.
