1、A-A-54794 15 January 1993 COMMERCIAL ITEM DESCRIPTION HUMIDIFIER, OXYGEN Diffuser Type The General Services Administration has authorized the use of this Commercial Item Description as a replacement for MIL-H-36746A, which is cancelled. This Commercial Item Description covers a sterilizable oxygen h

2、umidifier for use in open systems (oxygen mask, tent, etc.). Salient Characteristics: The humidifier shall be dual purpose, a bubbler humidifier and a jet type nebulizer, which generates oxygen (or air) into a fog for use in an open system (oxygen face mask, tent, etc. ) . Except for the reservoir a

3、nd diffuser, the complete unit shall be capable of repeated sterilization, 250F, 20 minutes. The complete unit shall be sterilizable and reusable. The system shall be designed to remain operational when it is tilted up to 20. The reservoir bottle shall have a working capacity of at least 200 cc. It

4、shall be fabricated of suitable transparent plastic permitting visual observation of the liquid level within the bottle. A high and low liquid level shall be clearly marked and identified on the bottle. There shall be approximately 200 cc capacity between the high and low liquid levels. The bottle s

5、hall be capable of withstanding an internal pressure of at least 20 psig without bursting. AMSC N/A FSC 6515 DISTRIBUTION STATEMENT A: Approved for public release; distribution is unlimited. Licensed by Information Handling ServicesThe humidifier shall be capable of maintaining a relative humidity a

6、t a body temperature as follows: a. As a bubble type humidifier, with oxygen flowing down through a syphon tube and out a diffuser at the bottom of the reservoir gaining humidity rising through the water to the outlet, from 35 percent relative humidity at 3 Lpm to 20 percent relative humidity at 12

7、Lpm. b. As a jet type nebulizer, with water or medicated solution being drawn up the syphone tube through an oxygen mixing orifice to the outlet, from 40 percent relative humidity at 3 Lprn to 67 percent relative humidity at 10 Lpm. The relative humidities shall be calculated by determining the weig

8、ht of water expended (with oxygen admitted to the humidifier at 70F - 73OF and 29 inches of mercury) and the resultant molal humidity of issuant gas. The vapor pressure of the issuant gas divided by its partial pressure of saturated vapor at 98.6OF, shall be defined as the relative humidity. The hum

9、idifier shall be provided with a removable, leakproof top. The top shall have: * an inlet connector, winged threaded DISS 1240 female swivel, 9/16 inch threaded, for 50 psig oxygen source * a relief valve * a selector switch to select bubble or jet operation, and * an outlet connector, 22 mm male, i

10、n accordance with ASTM F 1054. A leakproof barbed adapter for the outlet shall be provided which allows connection of 3/16 to 5/16 inch tubing. The pressure relief valve shall prevent internal pressure inside the humidifier from exceeding 2.5 psig. A warning whistle or other audible warning shall be

11、 provided which shall operate in conjunction with the pressure relief valve so designed to provide audible sound if the tubing becomes obstructed when the oxygen flow is as low as 3 Lpm, but shall not sound an alarm when a free flow is being used through an unobstructed, 48 inch long delivery tube a

12、nd catheter. The humidifier shall be supplied with operating and maintenance instructions. 2 Licensed by Information Handling ServicesA-A-54794 m 999997q OL2L502 T48 m Workmanship.
