## Abstract

An embalming machine for mixing of fluids and cleaning of a reservoir may include a reservoir. The embalming machine may include a tube extending from a lower portion to an upper portion of the reservoir, the tube providing a pathway for fluid to travel to the reservoir. The embalming machine may include a port connected to an end of the tube adjacent to the upper portion of the reservoir, the port being configured to dispense the fluid traveling through the tube and into an interior of the reservoir.

## Claims

### Claim 1

An embalming machine comprising:
a reservoir;
a tube extending from a lower portion to an upper portion of the reservoir, wherein the tube provides a pathway for fluid to travel to the reservoir; and
a port at an end of the tube adjacent to the upper portion of the reservoir, wherein the port is configured to dispense the fluid traveling through the tube into an interior of the reservoir;
an inject outlet;
a pump operable to pump fluid from the reservoir and to the inject outlet and/or the port;
a mix solenoid to which fluid flows from the pump to be directed to the tube to dispense fluid from the port into the reservoir to facilitate mixing of fluid in the reservoir;
a pressure regulator having a pressure relief bypass along which fluid flows to route fluid flowing from the pump back to the reservoir, the pressure regulator operable to control a proportion of the fluid routed to the reservoir via the pressure relief bypass to control a pressure of the fluid flowing from the pump;
a user interface configured to receive a pressure setting input for the embalming machine to cause the pressure regulator to set the proportion of the fluid flowing in the pressure relief bypass.

### Claim 2 (depends on 1)

The embalming machine according to claim 1 wherein the port is positioned to dispense fluid into the interior of the reservoir to flow in a generally centrifugal motion around the interior of the reservoir.

### Claim 3 (depends on 2)

The embalming machine according to claim 2 wherein at least a portion of the interior of the reservoir includes a hydrophobic surface.

### Claim 4 (depends on 1)

The embalming machine according to claim 1 further comprising a number of selectable settings, the selectable settings including, at least in part:
a clean mode; and
a mix mode.

### Claim 5 (depends on 1)

The embalming machine according to claim 1 wherein the pressure regulator is configured to cause fluid to be dispensed from the port and into the interior of the reservoir at a defined pressure based at least in part on the pressure setting.

### Claim 6 (depends on 1)

The embalming machine according to claim 1 wherein the pump is operable to cause fluid to be dispensed from the port and into the interior of the reservoir at a defined flow rate.

### Claim 7 (depends on 1)

The embalming machine according to claim 1 further comprising:
at least a second tube projecting from inside of the lower portion of the reservoir, wherein at least the second tube is configured to inject fluid into the interior of the reservoir.

### Claim 8 (depends on 1)

The embalming machine according to claim 1 further comprising:
a reservoir lid configured to at least partially enclose the upper portion of the reservoir,
wherein the reservoir lid includes an access hatch integrated into the reservoir lid.

### Claim 9 (depends on 1)

The embalming machine according to claim 1 further comprising an inject mode where the fluid is pumped to the inject outlet and to the port via the mix solenoid.

### Claim 10 (depends on 1)

The embalming machine according to claim 1 wherein the user interface includes a pressure regulator knob rotatable to input the pressure setting input.

### Claim 11 (depends on 4)

The embalming machine according to claim 4 wherein the user interface is further configured to receive an operation mode input selecting one of the selectable settings.

### Claim 12 (depends on 1)

The embalming machine according to claim 1 further comprising:
a hydraulic flow valve through which fluid flows to the inject outlet;
a flow rate sensor to monitor a flow rate of fluid flowing through the hydraulic flow valve; and
a control circuit operably coupled to the flow rate sensor and a display of the user interface, the control circuit configured to cause the flow rate to be presented on the display.

### Claim 13 (depends on 1)

The embalming machine according to claim 1 further comprising a flow sensor to monitor a flow rate of fluid in the embalming machine.

### Claim 14 (depends on 13)

The embalming machine according to claim 13 wherein the flow sensor is positioned to monitor flow from the pump to the inject outlet.

### Claim 15 (depends on 13)

The embalming machine according to claim 13 wherein the flow sensor is an ultrasonic flow sensor.

### Claim 16 (depends on 1)

The embalming machine according to claim 1 wherein the user interface includes at least one display screen to present a pressure reading.

### Claim 17

An embalming machine comprising:
a reservoir;
a tube extending from a lower portion to an upper portion of the reservoir, wherein the tube provides a pathway for fluid to travel to the reservoir; and
a port at an end of the tube adjacent to the upper portion of the reservoir, wherein the port is configured to dispense the fluid traveling through the tube and into an interior of the reservoir;
an inject outlet;
a pump operable to pump fluid from the reservoir and to the inject outlet and/or the port;
a mix solenoid to which fluid flows from the pump to be directed to the tube to dispense fluid from the port into the reservoir to facilitate mixing of fluid in the reservoir;
a pressure regulator operable to control a pressure of the fluid flowing from the pump;
a hydraulic flow valve through which fluid flows to the inject outlet;
a flow sensor to measure flow of fluid through the hydraulic valve to the inject outlet;
a user interface including a display; and
a control circuit operably coupled to the flow sensor and the user interface and configured to:
receive a flow rate value from the flow sensor;
cause the flow rate to be presented on the display.
