Description

injection aids

Rheumatoid arthritis (RA) is an autoimmune disease that attacks the tissues and other parts of the body near the joints, causing chronic swelling and pain. RA focuses on the synovial tissue within the joint. Autoimmune diseases occur when the body's immune system mistakens its tissues for foreign substances and attacks them with antibodies that find and destroy "intruders" in the synovial membrane. Patients with RA often have joint stiffness that begins in the fingers and toes, which causes joint pain and limited movement. These patients have difficulty moving their joints, which in turn makes it difficult to manipulate the device by hand. Most self-administered drugs require a drug delivery device, such as an autoinjector, and often these devices require the patient to manipulate the device to self-deliver a dose. Autoinjectors may be shroud operated or button operated. Button-actuated autoinjector devices generally include an actuation button disposed on the top of the device, which must be manipulated by the user to deliver the drug injection. Patients with RA have difficulty operating these devices due to limited movement of the joint.

In one embodiment, an injection actuation assist device is provided comprising a top surface, a bottom surface, an opening in the bottom surface for receiving an injection device, and a shaft extending between the top surface and the bottom surface. The device further includes a chamber having a first end and a second end and terminating in the opening, the chamber configured to receive a portion of the injection device and a plurality of ribs extending into the chamber for gripping the injection device includes The device may further comprise a notch in the opening for receiving a protrusion of the injection device when the injection device is received within the chamber, wherein accommodation of the injection device into the chamber and movement of the actuation aid toward the distal end of the injection device are provided. Operate the injection device to deliver the injection solution.

In another embodiment, a method of operating an injection device is provided. The method comprises placing the injection actuation aid over the injection device such that the injection device is disposed partially within a chamber of the injection actuation aid and at least one protrusion on an outer surface of the injection device is longitudinally aligned with a notch on the auxiliary device. include The method comprises inserting the injection device into a chamber of the auxiliary device until a button contacts a chamber ceiling of the auxiliary device, and until at least one protrusion of the injection device is removably received within a notch of the auxiliary device.

When received, it may be configured to receive the protrusion of the injection device 20 . Receiving the injection device 20 within the chamber 108 and applying a downward force towards the distal end of the injection device 20 against the injection actuation aid on the injection device 20 causes the injection device 20 to deliver the injection solution. make it work Actuation of the injection device 20 in this manner using the injection actuation aid device 100 is an autoinjector to inject a drug while pressing the distal or bottom end of the device against a target injection area to actuate the device to deliver an injection solution. Because there is no need to press the device, it helps patients with poor joint movement and difficulty moving their fingers.

Also, some patients lack dexterity or simply lack of hand strength, resulting in difficulty in operating the auto-injector device (or any injection device). The injection actuation aid device 100 embodiment described herein facilitates easier injections for these patients by converting the actuation of a button on a button operated autoinjector to, for example, an injection actuation aid device. Instead of manipulating the actuation buttons of the device while depressing the device onto the target scanning area, the user only needs to apply a downward force to the assistive device while gripping a shaft that is easy to hold and grip the device. When used with cap-actuated injection devices, the injection actuation aids make it easier to operate the autoinjector device by providing a more ergonomically shaped object (i.e., shaft) to grip while applying downward pressure towards the target site for injection. can do it

In another embodiment, a modification or surface treatment of the material of the injection actuation aid device 100 may be provided to enhance the user's ability to hold and grip the device during use. 7 provides a non-limiting example, wherein the shaft includes a ribbed feature on its outer surface.

In the injection actuation assist device 100 embodiment described herein, the user applies pressure to the device 100 once the autoinjector is placed within the device 100 and operates the autoinjector device to deliver a target injection to deliver the injection solution. You can also apply pressure to the area.

Further, for a button-actuated device in which a button for actuating the device is disposed on the top surface of the device, a downward force on the injection aid device 100 compresses the button through contact between the button and the chamber ceiling 112 . This causes the injection device to operate. This action may cause movement between the button actuated injection device and the injection actuation assist device.
