Problems solved by technology

However, the problem with this arrangement is that the device still requires two hands to operate (one hand to pinch the skin, the other to operate the syringe), thereby rendering it less accessible for injection into the patient's body. in the area
While this arrangement will allow for one-handed operation, the torque caused by twisting the fingers against the skin may make it difficult to stabilize the syringe during the injection procedure, thereby increasing the likelihood that the injection needle will inadvertently cut laterally through tissue and cause injury

Embodiment Construction

[0048] Now see the schematic figure 1 , provides a cross-sectional diagrammatic representation of a portion of a user's skin exhibiting the aforementioned "pinch" technique. As shown, by applying force to the skin in directions 1 and 3, the user can raise the skin fold 5 into which the needle 7 can be inserted, so that the needle extends through the epidermal layer 9, the dermal layer 11 and the access needle should advantageously enter subcutaneous tissue13. By using the pinch technique, as is well known in the art, it is less likely that a user will inadvertently insert a needle through the subcutaneous tissue and into the underlying muscle. Similarly, it is also unlikely that a user will inadvertently insert the needle at an angle into the dermis.

[0049] figure 2 is a schematic perspective view of the axial alignment of the attachment 15 and the illustrative injection pen 17 according to the first embodiment of the invention. Attachment 15 includes a generally annul...

Abstract

An attachment for an injection pen or syringe, the attachment being attachable to the needle or needle end of an injector pen (7) or syringe, the attachment comprising a circumferential array of inwardly pointing flexible fingers (9) configured such that when the flexible finger tips are pressed against the injection site the flexible fingers are capable of flexing axially and inwardly to promotethe gathering of a pucker of subcutaneous tissue in the vicinity of a needle insertion point.

Description

technical field [0001] The present invention relates to an attachment for an injection pen or a syringe. In preferred embodiments, the devices disclosed herein can improve the safety, comfort, and efficacy of self-administration of injectable drugs (eg, insulin). Background technique [0002] A considerable user group requiring self-administered injections is diabetics. Diabetics require regular injections of insulin as a lipid, and protein if taken orally would be digested and otherwise attacked by the immune system in the gastrointestinal tract. Type 1 diabetics can manage their condition with injections alone, as do a significant proportion of type 2 patients. [0003] While self-injection is an effective way to manage the condition, it is fraught with risk factors that can compromise efficacy. [0004] When injecting, it is important that the needle penetrates the epidermis (which is ~2mm thick) so that it can deliver insulin (in this particular example) to the fat-ri...
