Ohio Kinet-O-Meter 4000

WLMD ID: akxj
The Heidbrink Company introduced the Kinet-O-Meter machine in the mid-1930s. It was influential enough to attract the attention of competitors. Before the end of that decade, the Heidbrink Co. had been acquired by its rival, The Ohio Chemical and Manufacturing Company. For three decades, Ohio kept the well-respected Heidbrink name and continued to make the Kinet-O-Meter, in many configurations and with numerous modifications. Even after Ohio was in its turn acquired by other companies, this widely-used machine continued to be known as "the Heidbrink". Shown here is the Model 4000, also called the “Compact” Model, introduced around 1963. The various Kinet-O-Meter models were finally phased out in the late 1960s, when they were replaced by the Ohio Unitrol machine.

Note Type: General
Notes: The early year (1963) in the date range for the possible year of manufacture
for this machine is based on the earliest publication in which this machine
is mentioned (an ad in the journal Anesthesia & Analgesia). The end year
(1970) is an estimate based on the year that the Ohio Chemical & Surgical
Equipment Company changed its name to Ohio Medical Products (1967). This
machines has an oxygen knob (the Calverley knurled oxygen knob) that was
added to the machine after manufacture.

Note Type: Physical Description
Notes: One cabinet-style anesthesia machine on four wheels; The overall height
includes the Tycos gas gauge; The height of the cabinet with wheels is
approximately 97 cm; The width (70 cm) includes the gas tanks and carbon
dioxide absorber; The cabinet includes five drawers and one pull-out shelf;
Self-made plastic labels have been applied to the draws; The labels include
“CHARGE CARDS”, “LEVINE TUBE 3”, “BLOOD TUBES”, etc.; On the left side of the
cabinet are two yokes for nitrous oxide; The yokes have blue handles marked,
“N2O”; On the right side of the cabinet are two yokes for oxygen; These yokes
have green handles marked with “O2”; Above the pull-out shelf on the front
center of the machine are the following manufacturer markings, “OHIO” within
the company’s diamond shaped logo, and “Heidbrink [new line] COMPACT”; Above
this are three gas gauges, from left to right, labeled, “N2O”, “C3H6”, and
“O2”; Above these is a dial that may be pointed to one of three markings,
“VAPOR ON”, “VAPOR OFF”, “OXYGEN FLUSH”; Above these is the stainless steel
table top; On the front left corner of the table top is a supporting pole for
the CO2 absorber; The absorber is an Ohio Circle Absorber; On the center back
of the table top is a flowmeter bank; From left to right, the flowmeter bank
includes one white Verni-Trol, one orange cyclopropane, one blue nitrous
oxide and two green oxygen meters; Added to the left side of the bank is a
Verni-Trol flowmeter that is labeled for halothane; The Verni-Trol vaporizer
port for enthrane is located on the right side of the flowmeter bank; On top
of the flowmeter bank is a Tycos pressure gauge with increments numbered from
20 to 300O (in increments of 20); On the back of the machine is a yoke for
cyclopropane; This yoke has an orange handle; On the left back corner of the
machine is a Boehringer gas scavenger marked with “CATALOG # 5300”; Also on
the back of the machine are plats and stickers placed by the owner and
manufacturer; They include, “MID-MAINE MEDICAL CENTER [new line] 2624”, and
layers of Ohmeda maintenance stickers; Only the top sticker is visible; The
last maintenance date marked is “2-8-91”; The manufacturers markings include
the Ohio logo, “Heidbrink KINET-O-METER”, and the Airco logo”; Also on the

Note Type: Historical
Notes: Above the pull-out shelf on this cabinet-style anesthesia machine is the name
“Heidbrink COMPACT,” along with the manufacturer’s name and diamond-shaped
logo. Introduced by the Ohio Company around 1963 for use in smaller operating
rooms, it was also referred to as the Ohio-Heidbrink Compact Kinet-O-Meter,
and the Kinet-O-Meter 4000. It was made with two gas yokes for nitrous oxide,
two for oxygen, and one for cyclopropane. It was built with flowmeters for
these gases and an “Ohio Circle Absorber.” This example also has a Verni-Trol
vaporizer for halothane, and was most likely modified to vaporize “Enthrane”
sometime after its original purchase.

Dr. Heidbrink, a dentist and pioneering designer of anesthesia equipment,
introduced the first Kinet-O-Meter around 1934. It featured a dry flowmeter
in which the flow was indicated by a stem, or small rod, that slid up and
down a scale as gas flow increased or decreased. An updated version was
introduced in 1938, the same year that the Heidbrink Company was acquired by
the Ohio Chemical and Manufacturing Company. For decades, the Ohio Company,
and the companies that subsequently acquired Ohio, used the well-recognized
Heidbrink name for a series of popular anesthesia machines.
