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 an umbilical cord, said device comprising:

a control clamp having two legs, said two legs being interconnected at a hinge end by a hinge and having free ends at the opposite end, said free ends defining an opening therebetween, one of said two legs including a control part at the free end thereof,

a second clamp having two legs, said two legs of said second clamp being interconnected at a hinge end by a hinge and having free ends at the opposite end, said free ends defining an opening therebetween, and said two legs including at the free ends a catch for mutually locking said two legs in a fixed abutment position, and

a holder having two opposite wall members, each of said two opposite wall members being provided with two recesses for slidably receiving said two legs of the control clamp and said two legs of the second clamp, respectively, said holder further having a partition wall carrying a knife, said partition wall joining said two opposite wall members, and said knife protruding in one direction from said partition wall into a first interior part of the holder, said partition wall and said knife being arranged in parallel with a longitudinal plane of two recesses and so positioned as to enable the two legs of the control clamp and the two legs of the second clamp to pass on opposite sides of the knife while sliding in their respective recesses and the separation between said opposite wall members being just sufficient to allow the legs of the control clamp and the legs of the second clamp to slide in their respective recesses when the free ends of said legs of each said clamp are squeezed together,

wherein squeezing and cutting of the umbilical cord is performed by slidably inserting the hinge ends of the legs of the control clamp and the second clamp into the recesses, respectively, in the first interior part of the holder, inserting the umbilical cord in the opening between the two legs of the control clamp and the second clamp, and pressing together the holder and the control part at the control clamp, pushing the control clamp and the second clamp through the recesses, respectively, to first squeeze the umbilical cord between the legs and subsequently cut the umbilical cord, while passing the partition wall and the knife.

2. A device according to claim 1, wherein a tab area of the holder includes one outwardly projecting control tab at each of said two opposite wall members.

3. A device according to claim 1, wherein the two legs of the second clamp include recesses, and one of said two recesses of one of said opposite wall members is bounded by projections corresponding to said recesses of said legs of the second clamp.

4. A device according to claim 3, wherein slots are located extending in a longitudinal direction of the two legs of the control clamp and the second clamp.

5. A device for squeezing and cutting an umbilical cord, said device comprising:

a clamp having two legs interconnected by a hinge, free ends of said legs being spaced apart and yieldably movable towards each other while compressing the clamp,

a holder including recesses for supporting said two legs of said clamp, a knife and a tab area for bringing the holder from a first inactive position to a second position, in which the free ends of said legs are brought into mutual engagement, and the umbilical cord is squeezed and cut,

the holder including two opposite wall members being arranged, in the first inactive position and in the second position, substantially in parallel and being joined by a partition wall carrying the knife, each of said opposite wall members being provided with at least one throughgoing bore, so that a distance between the at least one throughgoing bore in each of said opposite wall members corresponds substantially to a maximum width of the clamp when compressed, so as to enable the holder to be slidably shifted on said clamp from the first inactive position at the hinge to the second position at the free ends of the legs thereof.

6. A device according to claim 5, wherein there are two sets of throughgoing bores.

7. A device according to claim 6, wherein the tab area of the holder includes one outwardly projecting control tab at each of said opposite wall members.

8. A method for squeezing and cutting an umbilical cord, said method comprising the following steps:

placing the umbilical cord between two legs of at least one clamp, and

shifting a knife carrying holder along said clamp, from a first inactive position to a second position, in which free ends of said two legs of said clamp are brought into mutual engagement, the umbilical cord thereby, in one single shifting step, being squeezed and cut, the knife carrying holder including a partition wall carrying a knife and the partition wall joining two opposite wall members slidingly receiving the two legs of the at least one clamp.

9. A method for squeezing and cutting an umbilical cord, said method comprising the following steps:

placing the umbilical cord between two legs of at least one clamp, said two legs being interconnected by a hinge, free ends of said legs being in a normal spaced apart position and yieldably movable towards each other while compressing the at least one clamp, and

shifting a holder having two opposite wall members arranged substantially in parallel and joined by a partition wall carrying a knife with each of said opposite wall members being provided with at least one throughgoing bore so that a distance between the at least one throughgoing bore in each of said opposite wall members corresponds substantially to a maximum width of the at least one clamp when compressed, so as to enable the holder to be slidably shifted on said clamp from a first inactive position at the hinge to a second position at the free ends of the legs thereof so that the free ends of said legs are brought into mutual engagement, and the umbilical cord is squeezed and cut.

10. A holder for squeezing and cutting an umbilical cord by use of a control clamp having two legs, said two legs being interconnected at a hinge end by a hinge and having free ends at the opposite end, said free ends defining an opening therebetween, one of said two legs including a control part at the free end thereof, and a second clamp having two legs, said two legs being interconnected at a hinge end by a hinge and having free ends at the opposite end, said free ends defining an opening therebetween, and said two legs including at the free ends a catch for mutually locking said two legs in a fixed abutment position, said holder comprising:

two opposite wall members, each of said two opposite wall members being provided with two recesses for slidably receiving the two legs of the control clamp and the two legs of the second clamp, respectively, and

a partition wall carrying a knife, said partition wall joining said two opposite wall members, and said knife protruding in one direction from said partition wall into a first interior part of the holder, said partition wall and said knife being arranged in parallel with a longitudinal plane of said two recesses and so positioned as to enable the two legs of the control clamp and the two legs of the second clamp to pass on opposite sides of the knife while sliding in their respective recesses and the separation between said opposite wall members being just sufficient to allow the legs of the control clamp and the legs of the second clamp to slide in their respective recesses when the free ends of said legs of each said clamp are squeezed together, wherein squeezing and cutting of the umbilical cord is performed by slidably inserting the hinge ends of the legs of the control clamp and the second clamp into the recesses, respectively, in the first interior part of the holder, inserting the umbilical cord in the opening between the two legs of the control clamp and the second clamp, and pressing together the holder and the control part at the control clamp, pushing the control clamp and the second clamp through the recesses, respectively, to first squeeze the umbilical cord between the legs and subsequently cut the umbilical cord, while passing the partition wall and the knife.
