Abstract

An improved disposable device for squeezing and cutting an umbilical cord comprising at least one clamp (1) having two legs interconnected by a hinge, said legs being supported in recesses of a holder (5). The holder further includes a knife (8). The umbilical cord is squeezed and cut when the holder is shifted along the clamp.

Claims

1. A device for squeezing and cutting a member, which device comprises:

a clamp having a pair of legs hinged together at a hinge at one end and openable apart to form an opening to receive a member between said pair of legs for squeezing and cutting the member;

a clamp holder mounted in sliding relationship with said clamp, engaging each of said legs of said clamp such that when the clamp holder is slid along said clamp from said one hinged end toward the other end of the pair of legs, said legs are thereby forced together by said clamp holder; and

cutting means carried by said clamp holder and positioned to pass alongside said opening between said pair of legs of said clamp so as to cut said member when present in said opening when said clamp holder is slid along said clamp.

2. A device as claimed in claim 1, wherein said clamp is provided with an abutment member distal from said hinge against which manual pressure is applied to slide the clamp with respect to the clamp holder.

3. A device as claimed in claim 1, wherein the clamp holder has a pair of oppositely directed finger engageable projections by which finger pressure is applied to slide the clamp holder along the clamp.

4. A device as claimed in claim 1, further comprising a second clamp having a pair of legs hinged together at one end and openable apart to form an opening to receive said member between said legs for squeezing and cutting;

wherein;

said clamp holder being mounted in sliding relationship with said second clamp such that said first and second clamps are positioned in a spaced apart mutually overlying relationship, such that said clamp holder engages each of said pairs of legs of each said clamp and the clamp holder is slid along said clamps in a sliding movement from said one end toward the other end of the pair of legs so as to force the pairs of legs of each clamp together,

and said cutting means being positioned on said clamp holder so as to pass between said mutually overlying clamps during said sliding movement of the clamp holder so as to cut said member held between said clamps when present in said openings when the clamp holder is slid along said clamps.

5. A device as claimed in claim 4, wherein said clamp holder is mounted in sliding relationship with said second clamp to permit removal of the second clamp from said clamp holder after completion of said sliding movement of the clamp holder.

6. A device as claimed in claim 4, wherein said second clamp is removed in a direction transverse to said sliding movement.

7. device as claimed in claim 4, wherein said clamp holder comprises a pair of opposed wall members connected by a web member carrying said cutting means, said clamps being received between said wall members and being compressed therebetween during said sliding movement.

8. A device as claimed in claim 7, wherein said wall members have on each side of said web member projections directed into a gap between the wall members and spaced from said web member to define channels in each of which channels a respective said clamp slides.

9. A devices as claimed in claim 8, wherein the channels in which slides the second clamp are defined between said web member and longitudinally spaced projections from said wall members and said second clamp has recesses therein which align and match with said projections when the clamp is in a release position following sliding of the clamp member therealong;

whereby following squeezing and cutting of said member said second clamp is removed from the clamp holder transversely with respect to a direction of said sliding movement of said clamp holder by passage of said projections through said recesses.

10. A device as claimed in claim 7, wherein said cutting means is set back from a front in a direction of movement of the sliding movement of said clamp holder between the opposed wall members and is thereby shielded from accidental injury of the user.

11. A device as claimed in claim 4, wherein said second clamp has a catch located distally from said hinge for holding the legs of said clamp together once the legs have been squeezed together by said clamp holder.

12. A method for squeezing and cutting a member comprising positioning said member to extend through a squeezing and cutting device, which device comprises:

a clamp having a pair of legs hinged together at one end and openable apart to form an opening to receive said member between the legs for squeezing and cutting;

a clamp holder mounted in sliding relationship with said clamp, engaging each of said legs of said clamp such that the clamp holder is slid along said clamp from said one end toward the other end of the legs of the clamp so that said legs are thereby forced together by said clamp holder; and

cutting means carried by said clamp holder and positioned to pass alongside said opening between said legs of said clamp in a sliding movement;

sliding said clamp holder along said clamp to close the legs of said clamp to squeeze said member, and cutting said member by the operation of said cutting means.
