Description

[0001] INJECTION ASSIST DEVICE

[0002] BACKGOUND

[0003] The use of needles and instruments containing needles are widespread in the medical industry. Needle insertion into a patient is an essential component of many clinical procedures such as biopsies, injections, neurosurgery, and cancer treatment methods. Certain disease states require daily injections, such as diabetes mellitus. The success of these procedures depends on accurate placement and correct technique during insertion of the needle into a target region of a patient. Accuracy of an injection can be hampered by certain factors, including a fear of needles leading to failure to administer an injection, or improper administration of an injection. Lack of knowledge and / or experience in administering injections to oneself or to others may also lead to improper injection administration.

[0004] Increased use of biologic and large molecule drugs has driven the demand for prefilled syringes and other drug delivery systems. Prefilled syringes arc combination products used in home and institutional settings by patients and health care providers (HCP). Failure to effectively use a prefilled syringe, for example, can result in errors that adversely affect the safe and full delivery of a prescribed dose. Training users of prefilled syringes and other needle- bearing drug delivery systems serves as an attractive strategy to mitigate errors and support the commercial objectives of syringe products and other medication administration products in the market.

[0005] Injectable medications are required for a number of varying illnesses and diseases. Many injectable medications require self-injection by a patient. Self-injection of a medicament using a device having a needle carries with it a certain stigma. Oftentimes users are weary of administering an injection for fear or anxiety related to handling an injection device, failing to deliver a complete dose of the medication, anticipated pain associated with injecting the subject with the needle, fear of accidentally sticking themselves with the needle during manipulation of the injection device, and difficulties in adequately grasping the dosing mechanism or injection device to inject the subject, among other concerns. An additional concern exists in instances in which users with little or no medical knowledge or experience are required to inject themselves or another subject using these devices. Performing a medical treatment or test using a device having or requiring a needle carries with it certain risks and often creates a level of anxiety for the user performing the treatment or test and / or for the subject receiving the treatment or test. Injections are often a source of fear and apprehension for injection providers as well as patients receiving injections. Studies suggest that as many as one-fifth to one-third of people with diabetes, for example, are hesitant or unwilling to give themselves insulin injections for reasons that include needle anxiety.

[0006] Additional concerns arise where particular steps must be followed during an injection, or where the correct positioning of the injection device must be used to prevent harm to the patient and to administer an injection correctly. Un-trained injection providers may not appreciate the deleterious effects that an improperly administered injection may cause including, but not limited to trauma to bone tissue caused by contact with the needle, injection into the incorrect layer of tissue reducing drug uptake or reduced efficacy, systemic poisoning as a result of incorrect placement of anesthetic injections and injection into the blood stream, for example, hematoma formation resulting from incorrect placement of the needle followed by aspiration during injections during anesthetic procedures, among other detrimental results of improper technique in positioning and placement of injection devices. Consequently, implementing an assist device that helps to position the needle for use while decreasing anxiety and pain associated with the injection for the user is needed.

In some non-limiting embodiments, the injection device may include a prefilled syringe (PFS) or an autoinjector, or injection training devices, optionally provided with or without needles and / or with or without medicament. The injection assist device includes multiple primary functions, some of which include to 1) provide a sensory distraction from the pain of needle insertion, 2) guide an injection device at a predetermined needle insertion angle to the target surface, which in some embodiments includes a 45-degree insertion angle of the needle, and 3) facilitate a consistent pinching of the skin across injections.

[0032] In order to minimize discomfort of an injection, the injection assist device may include a cooling element. This cooling element may include a copper plate to provide cold compression surrounding the injection site. The injection assist device may also, or alternatively, include agitation features which may include one or more agitation spikes on the surface of the device that interfaces the target surface. These agitation features provide agitation surrounding the injection site. These features may, in one non-limiting embodiment, be between 0.5-3.5 mm in diameter and 0.5-4 mm in height, each.

[0033] In FIG. 1, a perspective view of an embodiment of an injection assist device 100 is shown including a housing 110 including a guiding portion 112 and a stabilizing portion 114, said stabilizing portion comprising top surface 114A and a bottom surface 114B and a cooling element 116 provided on the bottom surface to contact a target surface of a user. The cooling element may include a cooler pack comprised of ice or a freezable or refrigerable material in one embodiment. In another embodiment, the cooling element may include a metal plate. The metal plate may include copper, aluminum, stainless steel, etc. or alloys of these and other metals. The cooling element 116 may include a thickness of 0.5mm-5mm in non-limiting embodiments.
