Definitions

  • This invention relates to the area of means for administering medication and in particular to the administration of medication in aerosol form and devices for delivering such medication.
  • Medication for people such as asthmatics is customarily administered in aerosol form and may be either to prevent or relieve symptoms. Although other types of medication can be administered in aerosol form, for convenience sake devices for aerosol medication administration will be discussed here in terms of asthma treatment.
  • aerosol dispenser is a metered-dose inhaler or "puffer" which consists of an aerosol unit and plastic mouthpiece.
  • metered dose can vary greatly depending on how such units are used.
  • the invention is a medication inhaler device having a generally elongate pen shaped body which includes a first upper component of the inhaler having external attachment means , a second component being a housing for a medication canister and a third component being a housing for a discharge nozzle mechanism such that medication can be discharged through a terminal end of the inhaler.
  • the engagement means be screw means.
  • the means for holding the inhaler to the apparel be a lever device which when not in use acts as a clip to attach to a pocket or the like and also acts as a cocking means for the canister and causes pressure to be applied to it.
  • the canister have a metered dose valve which engages with the nozzle and, when actuated by being depressed, sprays a measured amount of medication.
  • Fig. 1 shows a perspective view of the inhaler of the invention
  • Fig. 2 shows an exploded view of the components of the invention
  • Fig.3 shows a view of the interior of the inhaler
  • Fig. 4 shows the dispensing mechanism of the inhaler and the dispensing mechanism components
  • an elongate pen shaped medication dispensing inhaler 10 which has a body housing 20 which consists basically of 3 components which can be screwed together as shown in Figure 2.
  • a forward portion 21 holds a nozzle type dispensing mechanism while a central portion 22 acts as a housing for the medication holding canister and attachable to this is a housing 23 for a cocking mechanism to actuate the medication canister 30 to prepare the inhaler prior to discharge a dose of the medication.
  • the cocking mechanism includes a lever 40, a cam follower 41 , a plunger 42 and a return spring 43.
  • the lever 40 has a dual function in that it can be used to connect the inhaler to a pocket, in the same manner as a standard pen is attached to a pocket.
  • the lever is rotated through approximately 90 degrees its end 44 which is internal to the inhaler acts as a cam and applies pressure to the cam follower 41 which slides inside the inhaler.
  • the plunger 42 also slides within the inhaler and is sprung within the cam follower 41.
  • the lever 40 When the lever 40 is rotated as described its cam action acts against the cam follower which compresses the spring and causes the plunger to press against the top of the canister 31.
  • the canister 30 which holds the medication has a metered dose valve which, when activated can spray a measured amount of medication to the delivery nozzle 50.
  • the canister 30 has an outlet tube 32 which is inserted into the delivery nozzle 50 and is in fixed relationship with it.
  • the metered dose valve acts to discharge a metered dose of medication through the nozzle.
  • the arrangement is that pressure is applied to the canister by cocking the lever and that depression of the actuator 54 extending through the nozzle housing permits movement of the canister towards the delivery end 60 of the inhaler and relative to the outlet tube 32 thereby causing the medication to be discharged into the nozzle.
  • nozzle 50 Figure 3
  • nozzle support 52 Figure 3
  • actuator 54 nozzle support 52
  • pawl 55 The components of the nozzle assembly are shown in Figure 4 and include nozzle 50 ( Figure 3), nozzle support 52, actuator 54, pawl 55 and canister support 56.
  • the canister leading edge presses against the canister support.
  • This support in turn bears on the pawl which has two legs which rest on a step in a slot in the nozzle support 52.
  • the actuator 54 When the actuator 54 is depressed it deflects the legs of the pawl away from the step, which allows the pawl to slide in the direction of end 60 of the inhaler.
  • This movement allows the canister support 56 and canister 30 to move in the direction of end 60. As this movement of the canister is relative to the stationery delivery tube 32 the delivery of a metered dose of medication into the nozzle is effected.
  • the means of interconnection of the inhaler components is not restricted in this invention and it is envisaged that in another embodiment of the invention the nozzle and canister housing components could be unitary. Indeed the housing for the cocking mechanism could be unitary with the canister housing. Alternatively if the inhaler of the invention was designed to deliver one dose only the entire inhaler housing could be an integral unit.
  • the inhaler device is light weight and particularly easy to use. It is also envisaged that refills for the inhalers would be readily available at selected retail outlets. Although this invention is particularly useful in relation to the administration of asthma medication it is envisaged that any medications which are required to be delivered in an aerosol form could be used in the inhaler of the invention.
