Abstract
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 Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord, a hole in the housing enabling access to a thin wall membrane which is in contact with blood from the 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.
Claim 2
Dependent Claim
107 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord, a hole in the housing enabling access to a thin wall membrane which is in contact with blood from the 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.
Claim 3
Dependent Claim
188 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord; a cutter movably attached to said housing enabling cutting an umbilical cord and directing blood contained within the umbilical cord to a blood receiver; a shelf member on the cutter; and a clamp removably attached to the housing by means of a rocker and closable around the umbilical cord to collapse the cord and occlude blood flow therethrough, the rocker rotatably attached to said housing and having a first foot and a second foot, said first foot for engaging and holding the clamp on the housing, said second foot for engaging the shelf of the cutter whereby the shelf rotates the rocker thereby ejecting the clamp from the housing while maintaining the clamp on the umbilical cord when the cutter moves to enable cutting of the umbilical cord; 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.
Claim 4
Dependent Claim
188 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord; a cutter movably attached to said housing enabling cutting an umbilical cord and directing blood contained within the umbilical cord to a blood receiver; a shelf member on the cutter; and a clamp removably attached to the housing by means of a rocker and closable around the umbilical cord to collapse the cord and occlude blood flow therethrough, the rocker rotatably attached to said housing and having a first foot and a second foot, said first foot for engaging and holding the clamp on the housing, said second foot for engaging the shelf of the cutter whereby the shelf rotates the rocker thereby ejecting the clamp from the housing while maintaining the clamp on the umbilical cord when the cutter moves to enable cutting of the umbilical cord; 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.
Claim 5
Dependent Claim
139 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord, the housing including at least one communicating hole; a cutter movably attached to said housing enabling cutting an umbilical cord and directing blood contained within the umbilical cord to a blood receiver, the cutter including an upset pin for unseating an obstructor, the blood receiver removably attached to the housing and containing a vacuum which is exposed when the obstructor is unseated, the vacuum enabling collection of blood from the umbilical cord through the communicating hole in the housing; said housing holding said blood receiver and enabling fluid communication between the blood within. She umbilical cord and the blood receiver whereby the blood receiver receives blood contained in the umbilical cord in a clean manner.
Claim 6
Dependent Claim
139 words
Apparatus for cutting an umbilical cord and collecting a blood sample therefrom, comprising: a housing enabling receiving and entrapping a portion of umbilical cord, the housing including at least one communicating hole; a cutter movably attached to said housing enabling cutting an umbilical cord and directing blood contained within the umbilical cord to a blood receiver, the cutter including an upset pin for unseating an obstructor, the blood receiver removably attached to the housing and containing a vacuum which is exposed when the obstructor is unseated, the vacuum enabling collection of blood from the umbilical cord through the communicating hole in the housing; said housing holding said blood receiver and enabling fluid communication between the blood within. She umbilical cord and the blood receiver whereby the blood receiver receives blood contained in the umbilical cord in a clean manner.
Claim 7
Dependent Claim
70 words
The apparatus of claim 3 further comprising at least one needle mounted in the communicating hole in the housing and mounted to the blood receiver to thereby provide communication of the vacuum within the blood receiver to the communicating hole in the housing, and a protector movably attached to the housing for covering the at least one needle which is exposed when the blood receiver is removed from the housing.
