Abstract
The invention relates to a needle guard for use in a medical device, in particular for use in a catheter device, including a base portion having a needle passage extending in an axial direction from a proximal side of said base portion through said base portion to a distal side of said base portion wherein a needle shaft having a principle outer profile can be movably arranged in said needle passage; first and second arms extending substantially in said axial direction from said distal side of said base portion, wherein said first arm has a distal region and a proximal region; and a distal wall transversely arranged at said distal region of said first arm. The invention further relates to a catheter apparatus including such a needle guard and a needle.
Claims20
A needle guard (26) for use in a medical device, in particular for use in a catheter device (10), including:
- a base portion (44) made of a first material and having a needle passage (56) extending in an axial direction (A) from a proximal side (58) of said base portion (44) through said base portion (44) to a distal side (60) of said base portion (44) for movably receiving a needle shaft (28) having a principle outer profile;
- first and second arms (46, 48) extending substantially in said axial direction (A) from said distal side (60) of said base portion (44), wherein said first arm (46) has a distal region (62) and a proximal region (64);
- a distal wall (50) transversely arranged at said distal region (62) of said first arm (46);
- and
- a stopping element (38) made of a second material different from said first material, which is arranged in said needle guard (26) and has a through-bore (74) with a profile that is adapted to the principal outer profile of the needle shaft (28).
A needle guard (26) for use in a medical device, in particular for use in a catheter device (10), including:
- a base portion (44) made of a first material and having a needle passage (56) extending in an axial direction (A) from a proximal side (58) of said base portion (44) through said base portion (44) to a distal side (60) of said base portion (44), wherein a needle shaft (28) having a principal outer profile can be movably arranged in said needle passage (56);
- first and second arms (46,48) extending substantially in said axial direction (A) from said distal side (60) of said base portion (44), wherein said first arm (46) has a distal region (62) and a proximal region (64), and wherein a recess (68) is provided in said proximal region (64) of said first arm (46);
- and
- a distal wall (50) transversely arranged at said distal region (62) of said first arm (46).
A needle guard (26) for use in a medical device, in particular for use in a catheter device (10), including:
- a base portion (44) made of a first material and having a needle passage (56) extending in an axial direction (A) from a proximal side (58) of said base portion (44) through said base portion (44) to a distal side (60) of said base portion (44), wherein a needle shaft (28) having a principal outer profile can be movably arranged in said needle passage (56);
- first and second arms (46,48) extending substantially in said axial direction (A) from said distal side (60) of said base portion (44), wherein said first arm (46) has a distal region (62) and a proximal region (64);
- and
- a distal wall (50) transversely arranged at said distal region (62) of said first arm (46), wherein a groove (70) is provided in a side (66) of said distal wall (50) said groove (70) extending substantially in said axial direction (A).
A catheter apparatus (40), including:
- a catheter tube (14);
- a catheter hub (12);
- a needle (20) having a needle tip (30), a needle shaft (28) and a needle hub (42), wherein said needle shaft (28) has a distal section (34) and a proximal section (36), with at least the proximal section (36) having a principal outer profile;
- and
- a needle guard (26) in accordance with any one of the preceding claims, wherein said needle shaft (28) has an enlargement (32) between said distal section (34) and said proximal section (36), said enlargement (32) having an increased outer profile a dimension of which is larger than a maximum dimension of the profile of the needle passage (56) and/or the stopping element (38).
