Abstract
Mixing of substances is known to increase, in some cases, lability of one or more of the constituent molecules in the mixture. In some cases, such admixture of substances may lead, in addition to instability of one or more molecules, to decomposition of labile molecules. Such instability and/or decomposition may be due to concentration effects, enzymatic action, heat, light, a redox reaction, other components in the same solution reacting with labile molecules, physicochemical factors such as pH, and/or solvent effects. It will be appreciated that a lack of stability of a molecule represents a major cause for concern in medical chemistry. The present disclosure relates to a respiratory passage sprayer for administration of substances to a subject and a method of use of the respiratory passage sprayer.
Description
A RESPIRATORY PASSAGE SPRAYER AND METHOD OF USE OF SAME
Field of the Invention
The present disclosure relates to a respiratory passage sprayer for administration of substances to a subject and a method of use of the respiratory passage sprayer.
Background of the Invention
Mixing of substances is known to increase, in some cases, lability of one or more of the constituent molecules in the mixture. In some cases, such admixture of substances may lead, in addition to instability of one or more molecules, to decomposition of labile molecules. Such instability and/or decomposition may be due to concentration effects, enzymatic action, heat, light, a redox reaction, other components in the same solution reacting with labile molecules, physicochemical factors such as pH, and/or solvent effects. It will be appreciated that a lack of stability of a molecule represents a major cause for concern in medical chemistry.
Accordingly, a device and method to reduce instability and/or decomposition of one or more labile molecule(s) in preparations for administration to animals would be of benefit for the extension of the shelf-life of such preparations.
A particular benefit would be derived where the device and/or method relates to potentially labile substances for administration to a subject facilitates mixture of one or more labile substance with another substance shortly before administration to the subject without exposure to contamination of the mixed substances.

The respiratory passage sprayer 100 also includes an actuator 108 having a shaft 1 10 with a proximal end 1 12 and a distal end 1 14 opposite the proximal end 1 12 located along a central longitudinal axis 1 16 of the shaft 1 10. A portion 1 18 of the distal end 1 14 of the shaft 1 10 is configured to breach the first chamber 104 to enter the second chamber 106. The distal end 1 14 of the shaft 1 10 can include a point (NS) configured to puncture a seal 122 attached to the first chamber 104. The nozzle 102 is removable from a housing 124 that holds the first chamber 104 and the second chamber 106.
Specifically referring to Fig. 2, the shaft 1 10 includes at least one vane 120 spaced from the distal end 1 14 and projecting from the shaft 1 10, which is configured to move within the second chamber 106 when the actuator 108 is actuated by a user (NS). It will be appreciated that the shaft 1 10 may cause the at least one vane 120 to be rotated in a circular motion about the central longitudinal axis 1 16 when the actuator 108 is actuated by the user (NS). The first chamber 104 is shaped and configured to accommodate a cartridge or bladder 126 holding the first substance.
Specifically referring to Figs. 1 and 2, the respiratory sprayer 100 includes a channel 136, which upon actuation, communicates between the second chamber 106 and the nozzle 102 to deliver a mixture (NS) of the first substance from the first chamber 104 with the second substance from the second chamber 106. The actuator 108 includes a spring 109 for reciprocating the actuator 108 from a first position (NS) to a second position (NS) during actuation.
Specifically referring to Fig. 3, the respiratory passage sprayer includes a level detector 328 for measuring a level selected from the group consisting of: the first substance level in the first chamber 104, the second substance level in the second chamber 106, and a mixture of the first substance and the second substance in the second chamber 106 following admixture of the first substance and the second substance in the second chamber 106.
It will be appreciated that the channel 136 can be concentrically located around the shaft 1 10. It will also be appreciated that the first chamber 104 of the respiratory passage sprayer 100 may include a coaxial channel configured to permit the delivery of a mixture of the first substance from the first chamber 104 with the second substance from the second chamber 106, the channel being closed off from the first chamber 104.
