Abstract

There is disclosed herein a device for clamping and cutting an umbilical cord so as to enable blood samples from the umbilical cord to be collected and/or tested. The device provides for the clamping of a severed end of an umbilical cord and the automatic ejection of that clamped end. The device also provides for the cutting of an umbilical cord without using excessive force regardless of the size of the umbilical cord. Additionally, the device provides for the valved use of vacuum tubes to collect umbilical cord blood samples. Furthermore, the device enables the measurement of blood values at the moment of cutting the umbilical cord. Finally, the device also provides for the protection of users and others from exposure to sharps and blood.

Claims

1. Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising:

a housing enabling receiving and entrapping a portion of umbilical cord; and

a cutter movably attached to said housing enabling cutting an umbilical cord and directing blood contained within the umbilical cord to a blood receiver;

said housing holding said blood receiver and enabling fluid communication between the blood within the umbilical cord and the blood receiver whereby the blood receiver receives blood contained in the umbilical cord in a clean manner.

2. The apparatus of claim 1 further comprising an anvil attached to the housing for facilitating the cutter in cutting the umbilical cord.

3. The apparatus of claim 1 further comprising a safety lock attached to the housing for selectively preventing the cutter from moving.

4. An umbilical cord clamping and cutting device comprising:

a first housing and second housing movably connected together and movable to a closed position to entrap at least a portion of an umbilical cord;

a cutter attached to the first housing and movable from a disengaged position to an engaged position to thereby cut an entrapped umbilical cord;

an anvil attached to the second housing to encounter the cutter when said cutter is moved to an engaged position;

a first gel on the first housing and a second gel on the second housing for circumscribing the entrapped umbilical cord and thereby forming a seal around the cord and between the cord and the first housing and second housing; and

a blood collector removably attached to the first housing for collecting blood from the umbilical cord.

5. The device of claim 4 further comprising a safety lock attached to the first housing for selectively preventing the cutter from moving.
