Abstract

The present disclosure includes various examples for cooling electronics within a medical device while preventing or reducing the risk of an interior of the medical device being contaminated with a pathogen. The present disclosure includes a medical device having an air deflector to deflect potentially contaminated air from infecting a patient or caregiver. The present disclosure also includes medical devices with disinfectant devices installed to disinfect air either before entering the medical device or before exiting the device. Other examples of the present disclosure include medical devices that are sealed from outside air and fluids, and which may include a cooling device on an exterior surface which may be cleaned and/or removed after each use.

First claim

What is claimed is:

1. A mechanical cardiopulmonary resuscitation (CPR) device, comprising:
a central unit having an internal chamber with one or more electronic components;
a fan configured to intake air to the internal chamber;
an exhaust configured to eject air from the internal chamber;
an air deflector structured to direct air away from a head of a patient, wherein the air deflector is structured to tilt toward the lower body of the patient; and
a disinfectant device configured to disinfect air in the internal chamber.

2. The mechanical CPR device of claim 1 , wherein the air deflector is removable.

3. The mechanical CPR device of claim 1 , wherein the air deflector includes an air intake path and an exhaust path.

4. The mechanical CPR device of claim 3 , wherein each of the air intake path and the exhaust path are at least partially enclosed.

5. The mechanical CPR device of claim 3 , wherein the air intake path and the exhaust path define an opening structured to receive a piston of the mechanical CPR device.

6. The mechanical CPR device of claim 1 , wherein the air deflector includes a hose connected to the exhaust.

7. The mechanical CPR device of claim 6 , wherein the hose is a first hose and the mechanical CPR device further includes a second hose connected to the fan.

8. The mechanical CPR device of claim 1 , wherein the air deflector is “C” shaped.

9. The mechanical CPR device of claim 1 , wherein the air deflector attaches to the central unit.
