Technical Field

The present invention relates to a nasal fluid product dispensing device.

Background

Nasal dispensing devices are well known. It generally has a container containing one or more doses of a fluid product, and a dispensing head movable with respect to the container to dispense the fluid product, in particular by means of a pump, a metering valve or a piston sliding in the container. When the user wishes to use the device, he inserts the dispensing head into the nostril and activates the device to dispense a dose of fluid product, typically in the form of a spray.

One drawback of prior art devices relates to the efficiency of the dispensed fluid in the nostrils, particularly when the fluid product being dispensed is intended to act on the brain. In fact, due to the orientation of the drug delivery device in the nostrils, which varies from patient to patient, typically only a small fraction of the agent reaches the target area for such treatment, i.e. the olfactory region with the ethmoid sinus. However, it appears that this orientation determines whether the target area is well targeted, especially in the case of a closed spray for obtaining the maximum deposition in the target area.

Document WO2018109409 proposes a nasal dispensing assembly that associates a fluid product dispensing device with a positioning member having a plurality of facial support regions. The assembly is not compact and is bulky, having two discrete subassemblies.

Documents WO2006106208 and FR2798068 propose other devices of the prior art.

Detailed Description

The fluid product dispensing device shown in the drawings has a body 10 to which two nasal extensions 20, 30 are secured, at least one of the two nasal extensions being a nasal dispensing head. These nasal extensions 20, 30 extend from the upper surface 15 of the body for insertion into respective nostrils when the device is in use. Preferably, the axial extensions 20, 30 are relatively soft to avoid any risk of injury when inserted into the nostrils.

The central portion 16 of the upper surface 15 of the body 10, between the two axially extending portions 20, 30, bears upon the nasal septum when actuated. Advantageously, the central portion 16 may have a slightly concave or curved profile to fit the nasal septum, as shown particularly in fig. 4.

In a first advantageous embodiment shown in fig. 1 to 3 and 5 to 9, the two nasal extensions 20, 30 each form a nasal dispensing head which is provided with a dispensing orifice 21, 31, respectively. In this first embodiment, two variants of which will be described in more detail later, the actuation of the device causes the fluid product to be dispensed simultaneously into both nostrils.

In an advantageous second embodiment, shown in fig. 4, 10 and 11, one of the nasal extensions 20 forms a nasal dispensing head provided with a dispensing orifice 21, and the other nasal extension 30 forms a guide. In this second embodiment, two variants of which will be described in more detail later, the actuation of the device causes the fluid product to be dispensed into only one nostril.

The two nasal extensions 20, 30 are inclined, i.e. the axis X along which the two axial extensions 20, 30 extend, forms an insertion angle with respect to the longitudinal axis a of the body 10, which is a vertical axis in the orientation of fig. 1, 2 and 6 to 11. Preferably, the two nasal extensions 20, 30 are parallel.

The device according to the invention allows the dispensing head to be oriented in each nostril in a substantially predetermined manner so as to be aimed at the dispensing area to which the fluid product is dispensed in the nostril.

The insertion angle of each nasal extension 20, 30 into the respective nostril is therefore between 30 ° and 60 °, advantageously between 40 ° and 50 °, preferably about 45 °.

In addition, the insertion depth P of each dispensing head in the nostril is predetermined by the dimensions of the axial prolongations 20, 30 with respect to the upper surface 15 of the body 10, in particular with respect to the central portion 16 bearing against the nasal septum. Advantageously, the insertion depth is between 5 mm and 15 mm, preferably about 10 mm.

The body 10 has a hollow sleeve 11 which receives one or two containers 50, as described below.

Advantageously, the body 10 also has two outer arcs 14 adapted to receive the fingers of the user, in particular the index finger on the one hand and the middle finger on the other hand. In a variant, the user can press with his fingers on the upper surface 15, for example radially outside the two nasal extensions 20, 30.

An actuating member 40 is slidably mounted in the body 10 for actuating the device. Typically, the user places their thumb on the bottom of the actuation member 40 to effect actuation.

The device may be used to dispense liquid products as shown in fig. 6, 7 and 10, or the device may be used to dispense powders as shown in fig. 8, 9 and 11.

According to a first advantageous embodiment, the device dispenses the fluid product into both nostrils simultaneously.

To this end, the two nasal extensions 20, 30 each form a nasal dispensing head, each head being connected to a respective container 50.

Preferably, each container 50 contains a single dose of fluid product that is dispensed upon a single actuation. Thus, the device is referred to as a single-dose device because the entire fluid product is dispensed with a single actuation, even though one dose is dispensed simultaneously in each nostril. Alternatively, the invention may be applied to a multi-dose device, such as a dual-dose device.

Fig. 6 and 7 show a first variant of the first embodiment, in which the fluid product is a liquid. In this variant, each container 50 is fixed in the actuating member 40 and is therefore axially movable with respect to the body 10 upon actuation.

Preferably, each container 50 is formed by a hollow blind tube having only one axial opening closed by a piston 51 forming a sealing plug before actuation. Each head is connected to a needle 25, 35 which is fixed with respect to the body 10 and which, when activated, pierces the respective piston 51 as each piston 51 slides in the respective container 50, simultaneously dispensing the fluid product contained in each container 50 through the dispensing holes 21, 31.

Fig. 8 and 9 show a second variant of the first embodiment, in which the fluid product is a powder. Advantageously, this second variant uses components similar to those described in document WO 2015001281.

In this second variant, each container 50 is fixed in the body 10 and therefore cannot move axially with respect to the body 10 when actuated.

Each container 50 is formed by a hollow tube having an air inlet on one side and an outlet for the fluid product on the other side. The air inlet of each container is connected to an air driver and the fluid product outlet of each container is connected to a respective dispensing head. The fluid product outlet is closed before actuation by a closure 57, preferably a spherical bead, which is forcibly engaged in said fluid product outlet. The air inlet is provided with a fluid product retaining member adapted to retain the powder in the receptacle prior to actuation of the device. The air driver is formed by an actuating member 40, manually actuated by the user to generate an air flow which passes through each container 50 to drive the product contained by the container towards the respective dispensing aperture 21, 31.

The device has a mechanical opening system 46, 56 which is attached to the air driver, i.e. which is activated at the same time as the air driver is activated, adapted to cooperate with the closure 57 to mechanically drive the closure out of its closed position upon activation of the device. The mechanical opening system may have a set of levers 46, 56, a first lever 46 of which is attached to the actuating member 40 forming the air driver 20, and a second lever 56 arranged in the container 50, which second lever is pushed by said first lever 46 when the device is actuated. The lever sets 46, 56 will cooperate with the closure member 57 at the end of the actuation stroke to mechanically drive the closure member away from its closed position.

Advantageously, the fluid product retaining member may be made integrally with the second stem portion 56. Thus, the fluid product retaining means can be made in such a way as to be leaktight to the product and also to the air before actuation of the device, the air pressure generated by the air driver entering the container 50 only when said retaining means are pushed in movement by the first rod 46.

The air driver, not shown in detail, has a piston, for example formed on the actuating member 40, sliding in an air chamber, for example formed in the sleeve 11 of the body 10, said piston being manually actuated by the user when the user moves the actuating member 40 with respect to the body 10.

According to a second advantageous embodiment, the device dispenses a fluid product into only one nostril.

To this end, only one of the nasal extensions 20, 30 forms a nasal dispensing head and is connected to the container 50. The other nasal extension forms a guide for entry into the second nostril for guiding and orienting the device. Preferably, the dispensing head and guide are parallel, as shown in fig. 4.

Fig. 10 shows a first variant of this second embodiment, in which the fluid product is a liquid. This variant is similar to the previously described variant shown in figures 6 and 7.

Fig. 11 shows a second variant of this second embodiment, in which the fluid product is a powder. This variant is similar to the previously described variant shown in figures 8 and 9.

The present invention thus provides a device that is small, exquisite, easy to carry, intuitive to use, suitable in orientation and insertion depth, and adaptable to the user's shape.

The invention is particularly suited in the context of central nervous system therapy, such as therapy for neurodegenerative diseases of the parkinson's or alzheimer's class, which requires delivery of drugs through the nasal-brain barrier. Transnasal access to the target area, particularly the ethmoid sinus, is a simplified and non-invasive method of administering brain therapy. Other applications are contemplated, such as the treatment of autism, different forms of epilepsy, migraine, neurological disorders, attention deficit with or without hyperactivity disorder (TDAH), dementia, multiple arteriosclerosis, cerebrovascular disorders, brain tumors. The following molecules may be involved: insulin, oxidized toxins, dopamine, levodopa, stem cell therapy (brain tumors), rasagiline mesylate (antiparkinsonian drug), ropinirole (treatment of parkinson's disease), amantadine (an antiviral drug), sumatriptan (5-hydroxytryptamine (5-ht1) receptor agonist), huperzine a, curcumin, geniposide, rivastigmine (cholinesterase inhibitor for alzheimer's disease), rivastigmine tartrate (cholinesterase inhibitor for alzheimer's disease), doxepin, agomelatine (melatonin class), fluoxetine hydrochloride, tramadol hydrochloride (sedative-analgesic effect), noramitriptyline hydrochloride (antidepressant or therapeutic enuresis), venlafaxine (antidepressant), paliperidone (antidepressant). Drugs for the treatment of alzheimer's disease: donepezil, galantamine, rivastigmine, memantine, and mixtures of donepezil and memantine.

The invention has been described with reference to a number of advantageous embodiments and variants, but of course, various modifications can be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims.
