Abstract

Devices and methods for extraction and processing of substantiagelatineafuniculi umbilicalis (Wharton's Jelly) from an umbilical cord.

First claim

What is claimed is:

1. An apparatus for processing an umbilical cord, the apparatus comprising:
a base plate assembly, wherein the base plate assembly has a planar surface;
a bar coupled to the base plate assembly, wherein the bar is spaced from the planar surface such that a first gap exists between the bar and the planar surface;
a motor coupled to the base plate assembly, wherein:
the motor comprises a shaft with an eccentric pinion; and
the shaft with the eccentric pinion is generally perpendicular to the bar; and

a reciprocating blade coupled to the motor, wherein:
the reciprocating blade comprises a cutting edge that is parallel to the bar;
a second gap exists between the cutting edge and the bar; and
the second gap is approximately 1.0 mm.

2. The apparatus of claim 1 wherein the base plate assembly comprises a cover plate coupled to a base plate.

3. The apparatus of claim 1 wherein the bar comprises a flat surface proximal to the cutting edge of the reciprocating blade.

4. The apparatus of claim 1 further comprising a plurality of bars, wherein:
each bar in the plurality of bars is configured to couple to the base plate assembly; and
each bar in the plurality of bars is configured to provide a different gap spacing between each bar and the planar surface when coupled to the base plate assembly.

5. The apparatus of claim 1 wherein:
the reciprocating blade is coupled to the motor via a blade carrier;
the blade carrier comprises a slot; and
the eccentric pinion of the motor engages the slot.

6. An apparatus for processing an umbilical cord, the apparatus comprising:
a base plate assembly, wherein the base plate assembly has a planar surface;
a bar coupled to the base plate assembly, wherein the bar is spaced from the planar surface such that a first gap exists between the bar and the planar surface;
a motor coupled to the base plate assembly, wherein:
the motor comprises a shaft with an eccentric pinion; and
the shaft with the eccentric pinion is generally perpendicular to the bar; and

a reciprocating blade coupled to the motor, wherein:
the reciprocating blade comprises a cutting edge that is parallel to the bar;
a second gap exists between the cutting edge and the bar; and
the first gap is approximately 4 mm.

7. An apparatus for processing an umbilical cord, the apparatus comprising:
a base plate assembly, wherein the base plate assembly has a planar surface;
a bar coupled to the base plate assembly, wherein the bar is spaced from the planar surface such that a first gap exists between the bar and the planar surface;
a motor coupled to the base plate assembly, wherein:
the motor comprises a shaft with an eccentric pinion; and
the shaft with the eccentric pinion is generally perpendicular to the bar; and

a reciprocating blade coupled to the motor, wherein:
the reciprocating blade comprises a cutting edge that is parallel to the bar;
a second gap exists between the cutting edge and the bar; and

the bar is configured to snap into the base plate assembly when the bar is coupled to the base plate assembly.

8. An apparatus for processing an umbilical cord, the apparatus comprising:
a base plate assembly, wherein the base plate assembly has a planar surface;
a bar coupled to the base plate assembly, wherein the bar is spaced from the planar surface such that a first gap exists between the bar and the planar surface;
a motor coupled to the base plate assembly, wherein:
the motor comprises a shaft with an eccentric pinion; and
the shaft with the eccentric pinion is generally perpendicular to the bar; and

a reciprocating blade coupled to the motor, wherein:
the reciprocating blade comprises a cutting edge that is parallel to the bar;
a second gap exists between the cutting edge and the bar;
the motor and the reciprocating blade are contained in a motor and blade assembly and
wherein the motor and blade assembly comprises:
a motor housing configured to contain the motor;
a blade carrier configured to contain the reciprocating blade; and
a blade cover configured to couple to the motor housing and contain the blade carrier and the blade, wherein:

the motor and blade assembly is configured to be coupled to the base plate assembly and de-coupled from the base plate assembly without the use of tools;
the motor and blade assembly is configured to couple to the base plate assembly via one or more spring-loaded plungers;
the one or more spring-loaded plungers are configured to engage a groove in the motor housing when the motor and blade assembly is coupled to the base plate assembly;
the apparatus further comprises a release handle coupled to the one or more spring-loaded plungers; and
the one or more spring-loaded plungers are configured release from the groove in the motor housing when the release handle is pulled in a direction away from the groove in the motor housing.

9. The apparatus of claim 8 further comprising sliding shafts between the motor housing and the blade cover.
