FLUID COUPLING
A coupling that includes a male part and a female part. The male part has a distal most end, and a retaining projection having a retaining surface located proximal to the distal-most end of the male part. The female part has a retaining recess having a retaining top edge. The male part is configured to be received into the female part, and the retaining top edge of the retaining recess is configured to engage the retaining surface of the retaining projection. The male part may be connected to a medical hose and the female part may be connected to a medical device, or vice versa, wherein the medical device is a source of fluid, a thermal blanket, a pad, or a mattress.
1 ) A coupling for connecting together a medical hose and a medical device, the coupling comprising:
a male part comprising a distal most end, and a retaining projection having a retaining surface located proximal to the distal-most end of the male part;
a female part comprising a retaining recess having a retaining top edge;
wherein the male part is configured to be received into the female part, and the retaining top edge of the retaining recess is configured to engage the retaining surface of the retaining projection, and
wherein the male part is connected to the medical hose and the female part is connected to the medical device, or the female part is connected to the medical hose and the male part is connected to the medical device,
wherein the medical device is a source of fluid, a thermal blanket, a pad, or a mattress.
2 ) The coupling according to claim 1 , wherein the female part comprises a receiving recess,
wherein axial separation of the male part and the female part is permitted when the male part is received into the female part and the retaining projection is positioned within the receiving recess, and
wherein axial separation of the male part and the female part is restricted when the retaining projection is positioned within the retaining recess.
3 ) The coupling according to claim 1 , wherein the retaining projection is moved between the receiving recess and the retaining recess by rotating the male part and/or the female part.
4 ) The coupling according to claim 1 , wherein the retaining recess is defined between a clockwise edge and a counterclockwise edge, and
wherein the clockwise edge is arranged closer to a center of the female portion than the counterclockwise edge.
5 ) The coupling according to claim 1 , wherein the receiving recess is arranged radially adjacent to the retaining recess.
6 ) The coupling according to claim 5 , wherein the female part comprises a plurality of receiving recesses and a plurality of retaining recesses, and
wherein each retaining recesses is positioned between two adjacent receiving recesses.
7 ) The coupling according to claim 5 , wherein the plurality of receiving recesses and the plurality of retaining recesses are spaced apart equally.
8 ) The coupling according to claim 1 , wherein the female part comprises a socket having a socket contact wall, the distal-most end of the male part is configured to abut the socket contact wall.
9 ) The coupling according to claim 1 , wherein the female part comprises a socket into which the male part is received, an outer surface of the socket is scalloped.
10 ) The coupling according to claim 1 , wherein the female part comprises a distal-most end, and the retaining top edge is located proximal to the distal-most end of the female part.
11 ) The coupling according to claim 1 , wherein the male part comprises a collar comprising one or more gripping projections.
12 ) The coupling according to claim 11 , wherein the one or more gripping projections are generally aligned with the one or more retaining projections.
13 ) The coupling according to claim 1 , wherein the male part comprises a proximal portion comprising a rib.
14 ) The coupling according to claim 13 , wherein the rib is part of a thread.
15 ) The coupling according to claim 13 , wherein the proximal portion comprises an undercut region.
16 ) The coupling according to claim 1 , wherein the female part comprises a proximal portion comprising a rib.
17 ) An assembly comprising:
the coupling according to claim 1 , the medical device, and the medical hose,
wherein the female part is connected to the medical device and the male part is connected to the medical hose.
18 ) The assembly according to claim 17 , wherein the male part comprises a rib for threadably engaging the medical hose and an undercut region for at least a portion of the medical hose to engage.
19 ) The assembly according to claim 17 , wherein the medical device is an air source.
20 ) The assembly according to claim 17 , wherein the medical device is the thermal blanket.
