Medical Devices With Visual And Tactile Indicators

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.

What is claimed is: 
     
         1 . A medical device comprising:
 a device body having an end; and   a connector extending from the end of the device body in fluid communication therewith, wherein an outside surface of the connector includes a visual and tactile feature that is an indicator of a connection-type of the connector to a secondary component, the visual and tactile feature having a  3 -dimensional shape that indicates an insertion motion for engaging the connector with the secondary component, and the connection-type being defined by an inside surface of the connector, wherein the inside surface is smooth, the visual and tactile feature is one or more grooves or projections relative to the outside surface of the connector that are substantially parallel to a longitudinal axis of the medical device, and the connection-type is a slip-type connection.   
     
     
         2 . The medical device of  claim 1 , wherein the connector is engagable with one or more of: a needle hub, a filter, and an adapter. 
     
     
         3 . The medical device of  claim 1 , wherein the connector comprises an opaque material. 
     
     
         4 . The medical device of  claim 1 , wherein the connector comprises a collar disposed coaxially around an elongate tip. 
     
     
         5 . The medical device of  claim 1 , wherein the device body is a syringe barrel having a distal wall at the end and the connector extends from the distal wall. 
     
     
         6 . A syringe comprising:
 a syringe barrel having a distal end, a distal tip, an open proximal end, a barrel sidewall extending between the distal end to the open proximal end and defining a chamber, the distal end of the syringe barrel including a distal wall;   a connector extending distally from the syringe barrel at the distal wall and including a visual and tactile feature on an outside surface of the connector that is an indicator of a connection-type of the connector to a secondary component, the visual and tactile feature having a  3 -dimensional shape that indicates an insertion motion for engaging the connector with the secondary component, and the connection-type being defined by an inside surface of the connector;   wherein the visual and tactile feature is one or more grooves or projections relative to the outside surface of the connector that are substantially parallel to a longitudinal axis of the syringe and the connection-type is a slip-type connection.   
     
     
         7 . The syringe of  claim 6 , wherein the connector comprises a collar disposed coaxially around an elongate tip in fluid communication with the distal tip, a channel formed between the elongate tip and the collar, and an outside surface of the collar including the visual and tactile feature. 
     
     
         8 . The syringe of  claim 6 , wherein the connector comprises an opaque material. 
     
     
         9 . The syringe of  claim 6 , wherein the connector is compliant with ISO 80369-6 (2016). 
     
     
         10 . The syringe of  claim 6 , wherein the visual and tactile feature is effective to indicate an insertion motion for engaging the connector with one or more of a needle hub, a filter, and an adapter. 
     
     
         11 . The syringe of  claim 6 , wherein the syringe barrel comprises a glass material. 
     
     
         12 . The syringe of  claim 6 , wherein the syringe barrel comprises a polymeric material. 
     
     
         13 . A syringe comprising:
 a syringe barrel having a distal end, a distal tip, an open proximal end, a barrel sidewall extending between the distal end to the open proximal end and defining a chamber, the distal end of the syringe barrel including a distal wall;   a connector extending distally from the syringe barrel at the distal wall, the connector including a collar disposed coaxially around an elongate tip in fluid communication with the distal tip, a channel formed between the elongate tip and the collar, the collar including an inside surface, an outside surface, and a visual and tactile feature on the outside surface of the collar, the visual and tactile feature being an indicator of a connection-type of the connector to a secondary component and having a  3 -dimensional shape that indicates an insertion motion for engaging the connector with the secondary component, and the connection-type being defined by the inside surface of the collar;   wherein the visual and tactile feature is one or more grooves or projections relative to the outside surface of the connector that are substantially parallel to a longitudinal axis of the syringe, which are indicators of a slip-type connection.   
     
     
         14 . The syringe of  claim 13 , wherein the collar is a metal material and further comprises a syringe collar interface; and the syringe barrel is a glass material and further comprises a distal wall extension to which the syringe collar interface is connected. 
     
     
         15 . The syringe of  claim 13 , wherein the collar and the syringe barrel are both a polymeric material and the collar is integrally formed with the syringe barrel. 
     
     
         16 . The syringe of  claim 13 , wherein the collar comprises a 5% taper. 
     
     
         17 . The syringe of  claim 13 , wherein the collar is compliant with ISO 80369-6 (2016). 
     
     
         18 . The syringe of  claim 13 , wherein the visual and tactile feature is effective to indicate an insertion motion for engaging the connector with one or more of a needle hub, a filter, and an adapter. 
     
     
         19 . A method of making a medical device comprising:
 forming a connector including a visual and tactile feature on an outside surface of the connector, the visual and tactile feature being an indicator of a connection-type of the connector to a secondary component and having a 3-dimensional shape that indicates an insertion motion for engaging the connector with the secondary component, and the connection-type being defined by an inside surface of the connector; and   incorporating the connector in a device body of the medical device;   wherein the visual and tactile feature is one or more grooves or projections, which are indicators of a slip-type connection, relative to the outside surface of the connector that are substantially parallel to a longitudinal axis of the syringe, the inside surface being smooth.   
     
     
         20 . A method of distinguishing between different connection-type medical devices comprising:
 obtaining the medical device according to  claim 1 ; and   visually and/or tactilely inspecting the visual and tactile feature.
