1865: Clarks spray Producer

Figure 1

The Bergson tubes became "widely known among English practitioners," and they were used in a variety of products. One physician by the name of Dr. Andrew Clark of London used the tubes to create an inhaler of his own.  (1, page 465)

George Beaston said that Clark wanted to "have an instrument that would give a continuous spray, and with this view he had a pair of Bergson's tubes fitted into the cork of a graduated glass bottle, and had attached to them a double hand bellows with suitable valvular arrangements which allowed of a constant spray being kept up for an indefinite time. This instrument was made for him by Krohne & Sesemann (London surgical equipment producer) in the spring of 1865, and has since been known as Clark's spray producer. It is seen in Fig. 1, and it will be at once recognised as merely an improved edition of Bergson's original idea." (1, page 465-466)

You can see it was a little more compact than the original Bergson Inhaler, although still required some work to obtain a mist -- the squeezing of the bulb. There were various inhalers or nebulizers similar to this design, and you can see them by clicking on the link below.
