The present disclosure relates to safety devices that slide on a needle, clip securely on the needle, and shield the tip of the needle.
In clinical practice, injuries from needles are common, in particular because of blood and infective agents that contaminate the used needle. These injuries, which are occupational hazards of the medical profession, have resulted in inadvertent transmission of infective agents such as hepatitis C and human immunodeficiency virus. Sharps collection boxes, gloves and various safety practices are used to mitigate physical injuries arising from used needles, and to prevent infections from the needles. Also, devices that use active retraction, encased needles, shields, or self-blunting have been used (see, e.g., Elder et al (2006) Occupational Med. 56:566-574; Wilburn (2004) Online J. Issues Nurs. 9:5). However, the presently available safety devices for protecting against injuries and infections resulting from needles are not completely fail-safe. The present disclosure addresses this unmet need, by providing a new safety clip for a needle.
This application describes a clip that securely and removably attaches to a needle of a catheter assembly. The clip securely enshrouds a needle tip following use of the needle.
The clip can be configured to secure to a hub of a medical device, and is also configured to secure to a needle that is inserted at least partially through the hub. When in a secure mounted state, the clip is securely mounted on the hub, and when the clip is in a detached state, it is not mounted on the hub. The clip includes at least one tab that is configured to be placed into a corresponding at least one tab placement portion in the hub. The clip also includes a spring arm that presses against the needle in the mounted state, and that also presses against the needle in the detached state. The force of the spring arm against the needle is greater in the mounted state than in the detached state. The clip also includes a proximal aperture that stabilizes the needle and allows reversible movement of the needle through the proximal aperture of the clip in a direction parallel to the needle longitudinal axis in said mounted state. The proximal aperture prevents movement of the needle in a direction that is parallel to the longitudinal axis of the needle in the detached state. The clip also includes a distal aperture that allows reversible movement of the needle in the direction of the longitudinal axis of needle in said mounted state.
In addition, the clip can include a central aperture that allows reversible movement of the needle parallel to the longitudinal axis of needle in said mounted state, where the central aperture does not constrain needle movement relative to the clip in the direction parallel to needle longitudinal axis in said mounted state. Moreover, the proximal aperture does not exert stick-and-slip friction against needle in the mounted state, but does exert stick-and-slip friction against needle in the detached state.
In some implementations, the central aperture also does not exert stick-and-slip friction against needle in the mounted state. Moreover, the at least one tab can be male member and the at least one tab receipt portion of the hub can be a female member. The hub can be a catheter hub. The medical device can be a catheter and the needle can be a syringe needle. Between 50% and 100% of the mass of the clip can be exterior to the hub. The clip can be in an assembled combination with a hub or a catheter. The clip can be in an assembled combination with a needle and a hub, or with a needle and a catheter.
In some implementations, the needle can be inserted at least partially through the hub and at least 90% of the mass of the clip is not housed within or enclosed by the hub or the catheter. The clip includes a first aperture that stabilizes the needle and allows reversible movement of the clip along the longitudinal axis of needle in the mounted state, and a second aperture that allows reversible movement of the clip along the longitudinal axis of needle in said mounted state.
As used herein, including the appended claims, the singular forms of words such as “a,” “an,” and “the” include their corresponding plural references unless the context clearly dictates otherwise. All references cited herein are incorporated by reference to the same extent as if each individual publication, patent, and published patent application, as well as figures and drawings in said publications and patent documents, was specifically and individually indicated to be incorporated by reference.
In the description and claims below, various terms may be used for which the following definitions will apply:
Proximal and Distal
In the context of a medical device, such as an assembly having a longitudinal aspect, such as an assembly of a sheath and dilator, “proximal” refers generally to the end of the assembly that is closest to the physician while “distal” refers generally to the end that is inserted into the patient. Where the terms “proximal-to-distal movement” or “proximal-to-distal force” are used, these terms can refer to the context where the device is being used with the patient, and also in an abstract context, where a physician and patient are not present.
French Size
Diameters of catheters, cannulas, tubes, and the like, can be labeled by French size. This disclosure provides a tube with a French size that is, to provide non-limiting examples, 3 Fr (1 mm; 0.039 inches), 4 Fr (1.35 mm; 0.053 inches), 5 Fr (1.67 mm; 0.066 inches), 6 Fr (2 mm; 0.079 inches), 7 Fr (2.3 mm; 0.092 inches), etc. The corresponding diameters in millimeters and inches are shown in parenthesis. The French system has uniform increments between gauge sizes (⅓ of a millimeter) (Iserson K V (1987) J.-F.-B. Charrière: the man behind the “French” gauge. J. Emerg. Med. 5:545-548). Systems for measuring the outside diameter and inside diameter of lumens of catheters, needles, and the like have been described (see, e.g., Ahn, et al. (2002) Anesth. Analg. 95:1125). French size can refer to an inside diameter or to an outside diameter (see, e.g., U.S. Pat. No. 7,641,645 issued to Schur, which is hereby incorporated by reference).
Couplers and Locks
In some embodiments, the present disclosure provides a coupler or lock, such as a Luer lock or unisex Storz type coupler (see, e.g., U.S. Pat. No. 4,602,654 of Stehling et al). Locking tabs are also provided (see, e.g., U.S. Pat. No. 5,885,217 issued to Gisselberg et al). Also provided is a coupler with one or more radially-oriented protrusions that fit into one or more radially-oriented grooves (see, e.g., U.S. Pat. No. 6,336,914 of Gillespie). A locking collar can also be provided (see, e.g., U.S. 2005/0090779 of Osypka). Also provided is a coupler, with a proximal-to-distal (axially-oriented) pin or pins that fit into one or more slots (see, e.g., U.S. 2009/0143739 of Nardeo et al). Further provided is a threaded coupler (see, e.g., U.S. Pat. No. 7,422,571 of Schweikert et al). Each of the above patents and published patent applications are hereby incorporated herein by reference, in their entirety. In some embodiments, what is encompassed is a valve, or a medical device that includes a valve and that excludes any one of the above couplers. A coupler can couple a first hub to a second hub. For example, a first hub that is a catheter hub and a second hub that is a needle hub can be coupled. The first hub can be a catheter hub and the second hub can be a sheath hub.
The present disclosure encompasses medical devices, safety clips, and related methods of use. In every implementation disclosed below, the clip is not fully enclosed by a cowl or housing. In particular, 10% or less of the clip is enclosed by or within a cowl, housing, or hub. The clip of the present disclosure can also be used in combination with a catheter.
Methods and equipment are available to the skilled artisan for measuring structures, properties and functions of medical devices, such as catheters. The following references disclose methods and equipment for measuring, for example, tensile strength, force at break, elastic behavior, plastic behavior, microscopy for detecting microbial colonies or biofilms residing on the surface of catheters, or microbiological assays for measuring influence of anti-microbials. See, e.g., Aslam and Darouiche (2010) Infect. Control Hosp. Epidemiol. 31:1124-1129; Hachem et al (2009) Antimicrobial Agents Chemotherapy 53:5145-5149; Venkatesh et al (2009) J. Medical Microbiol. 58:936-944, which are hereby incorporated herein by reference. Methods and equipment for measuring tensile strength, elongation at break, and other properties of medical devices are also available. See, e.g., U.S. Pat. No. 6,039,755 issued to Edwin et al, and U.S. Pat. No. 7,803,395 issued to Datta et al, which are incorporated herein by reference. Above a limiting stress, called the elastic limit, some of the strain is permanent. In going beyond the elastic limit, a solid can either fracture suddenly or deform in a permanent way (see, e.g., Ashby M F, Jones D R H (2012) Engineering Materials 1, 4th ed., Elsevier, New York, pp. 115-133).
Coatings
The present disclosure provides, without limitation, coatings that comprise sulfobetaine, or carboxybetaine, hydrogels, polyurethane, polyester, polyethylene, polyamide, diblock polymers, layered coatings, interpenetrating polymer networks, or mixtures thereof. See, e.g., U.S. Pat. No. 7,879,444 issued to Jiang et al; U.S. 2009/0259015 of Jiang and Chen; U.S. 2009/0155335 of O'Shaughnessey et al; U.S. 2009/0156460 of Jiang et al; U.S. 2010/0145286 of Zhang et al; 2011/0097277 of Jiang et al; and U.S. 2010/0152708 of Li et al, each of which is individually incorporated herein by reference in its entirety.
Metals
The present disclosure provides metals, metal composites, plastics, ceramics, and other materials for manufacturing a clip. Also provided are materials, such as ribbons or leafs that are springs or have spring-like qualities. The skilled artisan is familiar with the relevant materials and techniques, including techniques for assessing torsion, flexibility, resiliency, pressure, friction, springiness, and so on. See, e.g., Walsh (2000) Handbook of Machining and Metalworking Calculations. McGraw-Hill; Nelson and Schneider (2000) Applied Manufacturing Process Planning: With Emphasis on Metal Forming and Machining. Prentice Hall; Strong (2007) Fundamentals of Composites Manufacturing: Materials, Methods and Applications, Society of Manufacturing Engineers; Bover and Gall (1984) Metals Handbook, Asm. Int'l The clip can be made substantially of one material. Alternatively, different parts of clip, for example, head, body, tail, and spring arm, can be made of different materials.
Aperture
An “aperture” encompasses any hole that is large enough to allow passage of a syringe needle. The syringe needle can have a diameter at a point along its substantially tubular portion that is in the range of 0.1-0.2 mm, 0.2-0.4 mm, 0.4-0.6 mm, 0.6-0.8 mm, 0.8-1.0 mm, 1.0-1.2 mm, 1.2-1.4 mm, 1.4-1.6 mm, 1.6-1.8 mm, 1.8-2.0 mm, and the like.
The present disclosure provides a clip that has a spring arm, where the spring arm is configured to be more flexible, or more resilient, or springier, than other parts of the clip. In this embodiment, the spring arm that is configured to be more flexible can be formed of a different material (e.g., different type of metal) than other parts of the clip. Alternatively, or in addition, the spring arm can be configured to be more flexible by taking the form of a strip, ribbon, or plank that is thinner than other parts of the clip.
As shown in
In some embodiments, the medical device does not comprise a safety clip contained entirely within a housing, within a shroud or cowl made of plastic, metal, or ceramic, within a hub, within a catheter, within a cannula, or within any housing.
