Many patient medicines are in liquid form and need to be injected into the subcutis, the fatty layer of tissue just under the skin (subcutaneous injections, “SQ”). As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption. Therefore, it is highly effective in administering vaccines, growth hormones, and insulin, which require continuous delivery at a low dose rate. For some pain and allergic medications, the subcutaneous tissue injections are the preferred choice. Typically, pinching a skinfold prior to injecting ensures that the drug is administered into the subcutaneous layer, as opposed to muscle.
Common subcutaneous sites are outer aspects of arms, thighs, buttocks and abdomen. Typically, individuals alternate the injection site each time to avoid soreness at any one sight. While it is fairly easy for an individual to pinch their abdomen and thighs with one hand and administer the injection with the other hand, it is quite difficult, and nearly impossible, for an individual to pinch their arm with one hand and administer the injection.
In one aspect, the present invention provides devices and methodology for preparing a skin for self-injection. The devices can be used to help an individual pinch himself when injecting medicine within a syringe. A device of the present invention is essentially a portable self-pincher device that can be used by an individual to pinch their skin so that the user then has access to both hands for administering a subcutaneous injection of medicine.
In one embodiment, a pinching device of the present disclosure includes a first head member including a handle portion, a jaw portion, and an intermediate portion therebetween, the handle portion having a terminal end with an engagement means; a second head member including a handle portion, a jaw portion, and an intermediate portion therebetween, the handle portion having an elongated end with a generally arcuate translating rack with an engagement means; and pivot means on the intermediate portions permitting the jaw portions to converge on the skin and grasp the skin in response to initial movement of the handle portions toward each other, thus creating a skinfold.
Further, a method for preparing a fold of skin of a user for self-injection is disclosed that comprises placing a pinching device of the present disclosure in an open position over the user's fold of skin, wherein in the open position, the terminal end of the first head member is disengaged with the rack of the second head member, thus creating a space between the jaw portions that is large enough to engulf the area of skin that requires pinching; squeezing, using a hand of the user, the handle portion of the first head member towards the handle portion of the second head member, wherein the engagement means on the terminal end of the handle portion of the first head member lock into position with the corresponding engagement means on the translating rack of the handle portion of the second head member; and creating a skinfold.
In one embodiment, a pinching device of the present disclosure includes two opposing clamping surfaces formed on upper ends of elongated rigid arms that are joined on lower ends by a resilient member such that the clamping surfaces are movable relative to one another through a fixed radius about a common pivot point, wherein the rigid arms and clamping surfaces are biased away from each other by the resilient member. In an embodiment, at least one of the rigid arms of the pinching device includes a locking mechanism sufficiently designed to lock the rigid arms in a compressed state so that the clamping surfaces are squeezed together and can squeeze a skin and lock in position so that a user will then have free use of both hands after creating a skinfold.
Also disclosed herein is a kit for preparing skin for a self-injection that includes a pinching device disclosed herein; a pair of pads for placement on the jaw portions or clamping portions of the pinching device; a flexible gooseneck arm; and a clip. In an embodiment, the kit is housed in a container.

Rigid arm 32a includes thumb locking mechanism 44 that is moveable within a slot 42 on the rigid arm 32a. Thumb locking mechanism 44 can be positioned anywhere on the rigid arm 32a. Thumb locking mechanism 44 can be a button or any device that the individual can use to lock the arms 32a and 34a in place. The movable locking mechanism 44 can be locked when the individual has a position that feels comfortable and the individual wants to secure the pinching device 100.
Arc arm 50a extends from arm 32a inward towards arm 34a. Arc arm 50a has an arcuate shape at approximately the same arc as the arc of the pivoting motion of clamping surfaces 38a, 40a. The arc arm 50a includes a plurality of saw tooth indents 52. A projection 46a extends from thumb locking mechanism 44 and can engage with a saw tooth indent 52 on the arc arm 50a as the clamping surfaces 38a, 40a are moved toward one another by compression of rigid arm 32a and 40a, as illustrated in
Arc arm 50b extends from arm 32b inward towards arm 34b. Arc arm 50b has an arcuate shape at approximately the same arc as the arc of the pivoting motion of clamping surfaces 38b, 40b. Rigid arm 34b includes a hole 37b which is sufficiently designed to engage with a ledge 46b on arc arm 50b. Ledge 46b can engage with hole 37b on rigid arm 34b as the clamping surfaces 38b, 40b are moved toward one another by compression of rigid arm 32b and 40b, as illustrated in
Although shown in
In an embodiment of use, when the pinching device 30 is used in conjunction with the clip/moveable arm, an individual would connect clip 10 of device 100 to a surface, the individual will adjust the arm 20 so that pinching device 30 is positioned in close proximity to a desired portion of the skin. Using the pinching device 30, the desired portion of the skin is grasped between the clamping surfaces 38, 40 by applying a compressive pressure over skin by squeezing rigid arms 32 and 40 together, thus creating a skinfold. Once clamping surfaces 38, 40 reach a pressure level, the pinching device 30 can be removably locked into position. In an embodiment, this engagement results in an interim lock which allows the user to fully remove their hands from the pinching device and skinfold so that the user has free use of both hands. The user may now use their free hand to inject themselves with medicine. Once the medicine has been administered, the user releases the locking mechanism releasing arms 32, 34 and clamping surfaces 38 and 40 are removed from skinfold 60. It should be noted that a pinching device of the present invention could be used alone, without the aid of the clip/moveable arm.
Handle portions 212 and 242 are movable about a central pivot 250 which passes centrally through intermediate portion 214 and intermediate portion 244. Handle 242 includes a generally arcuate translating rack 278 formed on an elongated end 243 of the handle 242. Handle 212 has a terminal end 275. The rack 278 includes engagement means, illustrated as a plurality of teeth 279 and the terminal end 275 also includes complimentary engagement means, illustrated as a plurality of teeth 277. Means to secure intermediate portions 214 and 244 generally comprises a screw aligned with slot 250 formed on each of the intermediate portions 214 and 244.
In an open position, the terminal end 275 of the handle 212 would not engage with the main rack 278 and the jaw portions 216 and 246 will be spread apart a distance that allows a portion of the skin that requires pinching to be within the opening created by the jaw portions 216 and 246.
In embodiments, a pinching device of the present invention is part of a kit that further includes a pair of pads for placement on the jaw portions or clamping surfaces of the pinching device; a flexible gooseneck arm; a clip; and a container for housing the items. In some embodiments, the kit further includes one or more instruction sets for instructing the user on how to use the device, specialized packaging, labels, decorative designs, coupons, and the like.
Those skilled in the art should appreciate that other improvements are possible and envisioned and fall within the scope of the invention.
