The present disclosure relates to a needlestick prevention device for use with syringes to administer injections, while providing vial stabilization for the withdrawal phase of injection.
A needlestick injury generally occurs in a medical environment, particularly during use of a syringe, when the user accidentally sticks the needle into themself or another person. The occurrence of needlestick injuries should be reduced and/or prevented, as they can spread diseases and infections, while also causing pain for the person who is stuck.
Needlestick injuries may occur at any time of injection, including while filling the syringe with a drug substance from a vial, while administering the injection, and while disposing of the injection device. A common form of protection against an injection needle is a protective cap, which is removed to administer an injection. Protective caps are typically disposed of following the delivery of an injection, as the replacement of the cap is thought to be a significant cause of needlestick injuries. While this method does protect against needlestick injury before injection, protection is not provided against a needlestick injury during and after the injection. Needlestick injuries with injections can still occur.
Another technique for preventing needlestick injuries during the phases of an injection includes the use of a safety shield, which is mounted on the needle-bearing syringe. The safety shield provides protection against needlestick injury once the disposable protective cap is removed. The user pivots the shield away from the needle to administer the injection, and pivots the shield back towards the needle into a locked position to protect from needlestick injury after the injection. This method alone provides protection against a needlestick injury after an injection, and when used in combination with a protective cap, provides protection against a needlestick injury both before and after an injection. Unfortunately, protection is not provided against a needlestick injury during the injection.
Additionally, products exist termed “vial adaptors” that aid in the safe withdrawal of liquid from vials, but such devices are not intended to be used for needlestick prevention purposes, nor do these products provide the ability to administer an injection while in use.
In light of the above, there is a present need for a needlestick prevention device that protects the user, or another person, from needlestick injuries which may occur while filling the syringe with a substance from a vial, while administering the injection, and once the injection is completed and the injection device is disposed of.
Embodiments of the present disclosure provide devices and methods that address the above needs, and others.

Embodiments of the disclosure described herein provide.
In the discussion and claims herein, the term “about” indicates that the value listed may be somewhat altered, as long as the alteration does not result in nonconformance of the process or device. For example, for some elements the term “about” can refer to a variation of ±0.1%, for other elements, the term “about” can refer to a variation of ±1% or ±10%, or any point therein.
As used herein, the term “substantially”, or “substantial”, is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, a surface that is “substantially” flat would either completely flat, or so nearly flat that the effect would be the same as if it were completely flat.
As used herein terms such as “a”, “an” and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration.
As used herein, terms defined in the singular are intended to include those terms defined in the plural and vice versa.
References in the specification to “one embodiment”, “certain embodiments”, some embodiments” or “an embodiment”, indicate that the embodiment(s) described may include a particular feature or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. For purposes of the description hereinafter, the terms “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, and derivatives thereof shall relate to the invention, as it is oriented in the drawing figures. The terms “overlying”, “atop”, “positioned on” or “positioned atop” means that a first element, is present on a second element, wherein intervening elements interface between the first element and the second element. The term “direct contact” or “attached to” means that a first element, and a second element, are connected without any intermediary element at the interface of the two elements.
Reference herein to any numerical range expressly includes each numerical value (including fractional numbers and whole numbers) encompassed by that range. To illustrate, reference herein to a range of “at least 50” or “at least about 50” includes whole numbers of 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, etc., and fractional numbers 50.1, 50.2 50.3, 50.4, 50.5, 50.6, 50.7, 50.8, 50.9, etc. In a further illustration, reference herein to a range of “less than 50” or “less than about 50” includes whole numbers 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, etc., and fractional numbers 49.9, 49.8, 49.7, 49.6, 49.5, 49.4, 49.3, 49.2, 49.1, 49.0, etc.

The vial body 15 can be inserted into the vial opening 10, as seen in
The syringe barrel 17 can be operably connected to the clamp 6. While the device 100 is designed such that syringe barrel 17 is pressed into the clamp 6, temporarily deforming the clamp 6, and then being maintained within the clamp 6 via a friction fit, the operably connection between syringe barrel 17 and the clamp 6 is not limited to a friction fit, and can include other connection modalities as well, including an adhesion substance.
The syringe barrel 17 can move axially/vertically along an interior surface of the clamp 6 by applying pressure to the syringe barrel 17, handle 7, rail connector 5 and/or rail connector end 9. The syringe barrel 17 is maintained at the shifted position by the radial friction and/or force of the portion of the clamp 6 that contacts the syringe barrel 17.
As seen in
As can be seen in
The structure of device 100 and syringe barrel 17 to move relative to each other, can maintain separation between the syringe needle 20 and a user, through a whole range of motion and use of the syringe barrel 17.
The structural configuration of the device 100 causes the syringe needle 20, the backing hole 21, and the vial cap 16 to all be substantially concentric, allowing for insertion of said syringe needle 20 into the vial for filling.
The structural configuration of the device 100 is such that the syringe needle 20 is encompassed in the inner tapered neck 14 (and/or the sheath 1) when not being used during withdrawal or injection.
The orientation of the device 100 as shown in
Upon removal of the vial body 15 from the device 100, the user can perform an injection with the syringe barrel 17 in contact with the clamp 6, such that the skin of a patient contacts the front face 11. Once the front face 11 is positioned to contact the skin of the patient, the syringe can be moved by pushing on the syringe tab 18 such that the syringe needle 20 moves through the backing hole 21 and is inserted into the patient. Then, the substance within the syringe barrel 17 can be administered to the patient by pressing the syringe plunger 19.
Once the substance is administered, the entire device 100, including the syringe needle 20, can be removed from the patient by pulling from the syringe tab 18. During this pulling process, the device 100 will remain connected to the syringe barrel 17 through syringe barrel 17's contact with the clamp 6. After removal of the syringe needle 20 from the patient, and after movement of the syringe barrel 17 such that the syringe needle 20 is separated from a user (and separated from the patient) by the interposition of the inner tapered neck 14 and/or the sheath 1, the syringe barrel 17 and the device 100 can be disposed of in the configuration shown in
A second embodiment of a device 200 is shown in
