Insufflators and related insufflation methods. In some embodiments, an insufflator assembly may comprise a first port fluidly coupled with and configured to provide access to ambient air, a gas pump fluidly coupled with the first port, and a second port configured to deliver pressurized ambient air generated from the gas pump for delivery to a patient. The assembly may further comprise a battery configured to provide a portable energy source for delivery of electrical energy to the gas pump.

1. A portable insufflator assembly, comprising: a first port fluidly coupled with and configured to provide access to ambient air; a gas pump fluidly coupled with the first port; a second port configured to deliver pressurized ambient air generated from the gas pump for delivery to a patient; and a battery configured to provide a portable energy source for delivery of electrical energy to the gas pump.

2. The portable insufflator assembly of claim 1, further comprising a filter configured to filter the ambient air prior to exiting from the second port.

3. The portable insufflator assembly of claim 1, further comprising a valve configured to open a venting port upon sensing a threshold pressure by the pressure sensor.

4. The portable insufflator assembly of claim 3, wherein the valve comprises a solenoid valve.

5. The portable insufflator assembly of claim 1, wherein the battery is removable.

6. The portable insufflator assembly of claim 1, further comprising a housing configured to enclose the gas pump and the battery, wherein the housing comprises a nylon material formed using an additive manufacturing technique.

7. The portable insufflator assembly of claim 1, further comprising an adapter configured to couple with a carbon dioxide cannister to allow for alternatively delivering carbon dioxide through a delivery port.

8. The portable insufflator assembly of claim 7, wherein the delivery port comprises the second port.

9. The portable insufflator assembly of claim 8, further comprising means for stepping down gas pressure from a carbon dioxide gas cannister to allow for, as an alternative to ambient air, delivery of carbon dioxide through a set of tubes through which the ambient air is delivered when the carbon dioxide cannister is disconnected from the medical insufflator assembly.

10. A medical insufflator assembly, comprising: an access port fluidly coupled with and configured to provide access to ambient air; a gas pump fluidly coupled with the access port; a delivery port configured to deliver pressurized ambient air generated from the gas pump; a filter assembly configured to filter ambient air received from the access port; a pressure sensor configured to sense an internal gas pressure; and a valve configured to open a venting port upon sensing a threshold pressure by the pressure sensor.

11. The medical insufflator assembly of claim 10, further comprising a battery configured to provide a portable energy source for delivery of electrical energy to the gas pump.

12. The medical insufflator assembly of claim 11, further comprising an alternating current converter to allow for use of alternating current for charging the battery or operating the medical insufflator assembly using an alternating current power source.

13. The medical insufflator assembly of claim 10, wherein the filter assembly is removable and replaceable.

14. The medical insufflator assembly of claim 10, further comprising an alarm configured to notify a user of a detection of a condition dangerous to a patient, the condition comprising at least one of a gas pressure and a gas flow rate exceeding a threshold.

15. A method for insufflating a patient during a surgical procedure, the method comprising the steps of: drawing ambient air into an insufflation device, wherein the insufflation device comprises a portable insufflation device configured to operate using a direct current source; pressurizing the ambient air within the insufflation device; and delivering pressurized ambient air through an incision in a patient using the portable insufflation device.

16. The method of claim 15, wherein the direct current source comprises a battery.

17. The method of claim 15, further comprising: filtering the ambient air through a filter assembly; removing the filter assembly; and replacing the filter assembly with a new filter assembly.

18. The method of claim 15, further comprising: coupling a carbon dioxide gas cannister with the portable insufflation device; and delivering carbon dioxide gas through an incision in a patient using the portable insufflation device.

19. The method of claim 18, further comprising: sensing a gas pressure exceeding a threshold gas pressure; and in response to sensing the gas pressure exceeding the threshold gas pressure, actuating a valve to prevent gas exceeding the threshold gas pressure from being delivered into the patient.

20. The method of claim 18, further comprising stepping down gas pressure from the carbon dioxide gas cannister from a first pressure at which the carbon dioxide cannister stores the carbon dioxide gas to a second, lower pressure to allow for, as an alternative to ambient air, delivery of carbon dioxide through a set of tubes through which the ambient air is delivered when the carbon dioxide cannister is disconnected from the portable insufflator device.
