Abstract

Connectors for medical devices include visual and tactile features as an indicator of a connection-type of the connector. This allows for differentiation by type of connection under busy and/or low light conditions.

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 15/480,903, filed on Apr. 6, 2017, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to medical devices having visual and tactile indicators. In particular, medical devices such as syringes, which are engagable with needle hubs, filters, adapters and the like, have one or more features on an external surface that provide visual and tactile indications of the type of connection that is internal to a component of the syringe, for example a slip-type connection or a lock-type connection.

TECHNICAL FIELD

BACKGROUND

Misconnection collars on both slip- and lock-type syringes have been implemented to avoid wrong-route medication errors. Wrong-route medication errors result from connections between unrelated delivery systems that have different intended uses (e.g. vascular, enteral, respiratory, epidural and intrathecal). The misconnection collars facilitate proper routing of fluids (e.g., medications, enteral feedings) or gases (e.g., oxygen) to a desired route into a patient. International Standard ISO 80369-1:2016(En) is directed to small-bore connectors for liquids and gases in healthcare applications. Small-bore connectors intended to be used for connections in neuraxial applications are to comply with ISO 80369-6. A requirement in ISO 80369-6 (2016), which is incorporated herein by reference, is a 5% taper.
State of the art misconnection collars for slip- and lock-type syringes are visually identical. Glass syringes have opaque collars, unlike many plastic syringes having clear collars, which make it difficult to differentiate by type of connection under busy and/or low light conditions. Plastic syringes may or may not be transparent and therefore it may also be difficult to differentiate plastic syringes by type of connection under busy and/or low light conditions.
There is a need to provide ways to differentiate between components that provide slip-type connections from those that provide lock-type connections.

DETAILED DESCRIPTION

Before describing several exemplary embodiments of the invention, it is to be understood that the invention is not limited to the details of construction or process steps set forth in the following description. The invention is capable of other embodiments and of being practiced or being carried out in various ways.
Visual and tactile features are provided on medical devices to provide ways to differentiate between connection types.
One or more embodiments provide a syringe that has a misconnection collar that will enable the syringe meet ISO 80369-6 (2016) misconnection requirements. According to one or more embodiments, the syringe can be utilized for neuraxial applications upon incorporation of the collar with a syringe barrel and it will be compliant to ISO 80369-6 (2016).
The following terms shall have, for the purposes of this application, the respective meanings set forth below.
Reference to “visual and tactile features” means those features that provide indicia by both their appearance, which is discernable by looking at the features, and by their 3-dimensional shape, which is discernable by touch. The visual and tactile features herein provide indicia about the type of connection, e.g., slip-type or lock-type, that is internal to a connector. The visual and tactile features of one or more embodiments indicate an insertion motion for engaging the connector with another component. For example, one or more grooves or projections that are substantially parallel to a longitudinal axis of a medical device indicate a straight, push-on motion. Alternatively, one or more grooves or projections that spiral at an angle greater than zero relative to an edge of a medical device that is perpendicular to its longitudinal axis indicate a turning, twist-on motion.
As used herein the term “connector” is understood to include any structure that is part of a neuraxial device that is capable of making a connection with a secondary neuraxial device. Non-limiting examples of connectors in accordance with the present invention include syringe tips, needleless connectors, male Luer connectors, female Luer connectors, side port valves, y-port valves, port valves, and other similar structures.
“Connection-type” refers to the mechanism by which the connector connects to another medical component. Connection-types include but are not limited to slip-type connections and lock-type connections. Slip-type connections are those that use a nominally linear motion to affix a medical device onto a connector. Lock-type connections are those that use primarily a twisting or turning motion to affix a medical device onto a connector. Other medical components to which connectors are connected include but are not limited to spinal needle assemblies, epidural needle assemblies, combined spinal and epidural (CSE) needle assemblies, fluid filters, adapters of tubing.
In FIGS. 1-2, a connector 100 having an outside surface 102 and an inside surface 104 comprises a collar 106 and an elongate tip 108. On the outside surface 102, there are visual and tactile features 110 that correspond to a connection type, which is defined by the inside surface 104. The inside surface 104 of this embodiment shows threads 112 that are at an angle of greater than zero to an edge 114 of the collar 106. Threads 112 define the connection-type as being a lock-type connection. The treads 112 are engagable with corresponding structures on another medical component such as lugs of a hub of an epidural needle assembly and the like. The motion of connecting to the treads 112 is twist-on. The visual and tactile features 110 comprise grooves that spiral at an angle greater than zero relative to the edge 114. Visually, the grooves follow a curved, twisting shape and tactilely, the touch of a finger will follow the curve of the grooves as an indication that a twisting motion would be needed to assemble the connector 100 with another component in a lock-type connection. While grooves are exemplified in this embodiment, projections could alternatively be used. The visual and tactile features do not contribute structurally to the engagement of the connector and another medical component. Connector 100 is opaque in this embodiment such that the threads 112 cannot be visually detected when viewing the outside surface 102.
FIG. 3 provides a medical device 120 and a connector 100 according to FIGS. 1-2 having the visual and tactile features 110. The device has a device body 122 and an end 124 from which the connector 100 extends. The medical device in this embodiment is a syringe, which comprises a syringe barrel 126, a distal wall 128, and a plunger 130. In one or more embodiments, the medical device is a polymeric material or a plastic and the connector is integrally formed with the device body 122. While the embodiment of FIGS. 1-3 shows an opaque connector 100, it is understood that connectors that are not opaque, e.g., transparent or semi-transparent, will also benefit from the present disclosure, for example, when there are low-lighting environments.
In FIGS. 4-5, a connector 150 having an outside surface 152 and an inside surface 154 comprises a collar 156 and an elongate tip 158. On the outside surface 152, there are visual and tactile features 160 that correspond to a connection type, which is defined by the inside surface 154. The inside surface 154 of this embodiment is smooth, which defines the connection-type as being a slip-type connection. The inside surface is engagable with another medical component that fits snugly into a channel formed between the collar 156 and the elongate tip 158, such as a hub of an epidural needle assembly and the like. The motion of connecting to the connector is slip-on. The visual and tactile features 160 comprise grooves that are substantially parallel to a longitudinal axis of the syringe. Visually, the grooves follow a straight shape and tactilely, the touch of a finger will follow the curve of the grooves as an indication that a push-on motion would be needed to assemble the connector 150 with another component in a slip-type connection. While grooves are exemplified in this embodiment, projections could alternatively be used. The visual and tactile features do not contribute structurally to the engagement of the connector and another medical component. Connector 150 is opaque in this embodiment such that the inside surface 154 cannot be visually detected when viewing the outside surface 152.
FIG. 6 provides a medical device 170 and a connector 150 according to FIGS. 4-5 having the visual and tactile features 160. The device has a device body 172 and an end 174 from which the connector 150 extends. The medical device in this embodiment is a syringe, which comprises a syringe barrel 176, a distal wall 178, and a plunger 180. In one or more embodiments, the medical device is a polymeric material or a plastic and the connector is integrally formed with the device body 172. While the embodiment of FIGS. 4-6 shows an opaque connector 150, it is understood that connectors that are not opaque, e.g., transparent or semi-transparent, will also benefit from the present disclosure, for example, when there are low-lighting environments.
In FIGS. 7-8, a connector 200 having an outside surface 202 and an inside surface 204 comprises a collar 206 and an elongate tip 208 and an interface 216. On the outside surface 202, there are visual and tactile features 210 that correspond to a connection type, which is defined by the inside surface 204. The inside surface 204 of this embodiment shows threads 212 that are at an angle of greater than zero to an edge 214 of the collar 206. Threads 212 define the connection-type as being a lock-type connection. The treads 212 are engagable with corresponding structures on another medical component such as lugs of a hub of an epidural needle assembly and the like. The motion of connecting to the treads 212 is twist-on. The visual and tactile features 210 comprise grooves that spiral at an angle greater than zero relative to the edge 214. Visually, the grooves follow a curved, twisting shape and tactilely, the touch of a finger will follow the curve of the grooves as an indication that a twisting motion would be needed to assemble the connector 200 with another component in a lock-type connection. While grooves are exemplified in this embodiment, projections could alternatively be used. The visual and tactile features do not contribute structurally to the engagement of the connector and another medical component. Connector 200 is opaque in this embodiment, e.g., metal, such that the threads 112 cannot be visually detected when viewing the outside surface 102.

While the embodiment of FIGS. 7-9 shows an opaque connector 200, it is understood that connectors that are not opaque, e.g., transparent or semi-transparent, will also benefit from the present disclosure, for example, when there are low-lighting environments.
In FIGS. 10-11, a connector 250 having an outside surface 252 and an inside surface 254 comprises a collar 256 and an elongate tip 258 and an interface 266. On the outside surface 252, there are visual and tactile features 260 that correspond to a connection type, which is defined by the inside surface 254. The inside surface 254 of this embodiment is smooth, which defines the connection-type as being a slip-type connection. The inside surface is engagable with another medical component that fits snugly into a channel formed between the collar 256 and the elongate tip 258, such as a hub of an epidural needle assembly and the like. The motion of connecting to the connector is slip-on. The visual and tactile features 260 comprise grooves that are substantially parallel to a longitudinal axis of the syringe. Visually, the grooves follow a straight shape and tactilely, the touch of a finger will follow the curve of the grooves as an indication that a push-on motion would be needed to assemble the connector 250 with another component in a slip-type connection. While grooves are exemplified in this embodiment, projections could alternatively be used. The visual and tactile features do not contribute structurally to the engagement of the connector and another medical component. Connector 250 is opaque in this embodiment, e.g., metal, such that the inside surface 254 cannot be visually detected when viewing the outside surface 252.
