Description

MEDICAL DEVICE WITH INTEGRATED DRESSING PAD
TECHNICAL FIELD
[0001] The present disclosure generally relates to medical devices with an integrated dressing pad, including syringes and catheters for delivering fluids into patients and drawing fluids such as blood from a patient, including a hypodermic needle. More particularly, embodiments of the present disclosure relate to medical devices including a slidably mounted integrated dressing pad, which can be passively activated without activation by an administering medical practitioner or can be actively activated by activation by the administering medical practitioner.
BACKGROUND
[0002] Medical devices that include hypodermic needles such as syringes, catheters and other medical devices that include a hypodermic needle. Hypodermic needles have many applications. One application a hypodermic needle assembled to a syringe, which can be used to insert the hypodermic needle into a person's body for intramuscular, subcutaneous, or intravenous injection of medications. Another application is to collect blood samples for tests using a hypodermic needle attached to catheter body such as a winged catheter, which involves inserting a distal puncturing end of the hypodermic needle into a person's vein while an inverted rubber-capped vacuum tube is pushed into the barrel so that the other end of the needle pierces the rubber cap of the vacuum tube. Thus, a blood sample passes from the vein, through the hypodermic needle, and into the vacuum tube.
[0003] The use of a medical device including a hypodermic needle involves puncturing the skin of a patient, withdrawing the hypodermic needle from the patient, and then application of a wound dressing at the site of injection after the needle is removed from the patient. When a medical practitioner such as a doctor, nurse, phlebotomist, physician assistant, emergency medical technician, or paramedic applies a dressing, typically a bandage or a gauze wrapped with medical tape to the patient at the site of injection. A bandage requires opening of a separate package and peeling tabs from the adhesive bandage. Application of gauze and applying tape over the gauze requires opening a package of gauze, peeling tape from a roll and placement of the tape. Application of the dressing requires the medical practitioner to use two hands to open the packaging, apply the dressing and dispose the waste from the packaging. In a busy medical practice environment, these steps are time-consuming and require additional supplies that take up space in medical facilities and are responsible for additional waste that requires disposal. In addition, by placing the dressing manually at the injection site, there is a chance of error in placement of the dressing as the injection site location may become unclear after withdrawal of the hypodermic needle. Further, there is a lack of compliance in dressing placement and use after hypodermic needle withdrawal from a patient. There is a need to provide improvements in the application of dressing at site of insertion of the hypodermic needle upon removal of the hypodermic needle from the patient. It would be desirable to provide a more streamlined procedure for hypodermic needle injection retraction and dressing application to improve dressing application compliance without increasing the number of steps for the procedure.
SUMMARY
[0004] A first embodiment of the disclosure pertains to a medical device comprising a hypodermic needle having a distal tip configured to be inserted into a patient at an insertion location and a proximal end attached to a needle hub, the hypodermic needle having a length between the distal tip and the proximal end; and an integrated dressing pad assembly mounted to and positioned with respect the medical device or packaging for the medical device so that the integrated dressing pad assembly is configured to be slidably engaged along the length of the hypodermic needle and applied to a patient at the insertion location when the medical device is used and the hypodermic needle is removed from the patient.

DETAILED DESCRIPTION
[0026] In this disclosure, a convention is followed wherein the distal end of the device is the end closest to a patient, e.g., for delivery of one or more drugs to the patient, and the proximal end of the device is the end away from the patient and closest to a clinician or other medical practitioner. With respect to terms used in this disclosure, the following definitions are provided.
[0027] As used herein, the use of "a," "an," and "the" includes the singular and plural. [0028] As used herein, the term "Luer connector" refers to a connection collar that is the standard way of attaching syringes, catheters, hubbed needles, LV. tubes, etc. to each other. The Luer connector consists of male and female interlocking tubes, slightly tapered to hold together better with even just a simple pressure/twist fit. Luer connectors can optionally include an additional outer rim of threading, allowing them to be more secure. The Luer connector male end is associated with a syringe discharge tip and can interlock and connect to the female end that is incorporated within a proximal end of a needle hub of a drug dispensing needle or filling needle for aspirating a drug from a drug vial into a syringe. Luer connector female ends are commonly located on vascular access devices (VADs).
[0029] As used herein, ISO 80369-7:2016 defines a specification for standard Luer connectors including a 6% taper between the distal end and the proximal end. A male standard Luer connector increases from the open distal end to the proximal end. A female standard Luer connector decreases from the open proximal end to the distal end. According to ISO 80369-7:2016, a male standard Luer connector has an outer cross-sectional diameter measured 0.75 mm from the distal end of the tip of between 3.970 mm and 4.072 mm. The length of the male standard Luer taper is between 7.500 mm to 10.500 mm. The outer cross-sectional diameter measured 7.500 mm from the distal end of the tip is between 4.376 mm and 4.476 mm. As used herein, the phrases "male standard Luer connector" and "female standard Luer connector" shall refer to connectors having the dimensions described in ISO 80369-7, which is hereby incorporated by reference in its entirety.
