The attachment is connected to a sprayer device which also includes at least one air compressor, a compressed air output port and an air inlet port.

Background

Disclosure of Invention

in order to solve the above technical problems of the prior art, the present invention provides an attachment for removing mucus from the upper respiratory tract of a patient, which overcomes the above disadvantages of the prior art and stably removes mucus with high efficiency even when applied to an immature patient.

In addition, the invention provides a method for applying the device system described above for medical treatment of the respiratory tract, which is simple and effective.

In the present invention, the mucus removal attachment of a nebuliser device comprises at least one suction nozzle comprising a suction orifice adapted to be inserted into at least one nostril, at least one air outflow, and means for retaining mucus between said suction orifice and air outflow, wherein the nebuliser device comprises at least one compressor, an air inlet and at least one compressed air outlet.

Preferably, the accessory further comprises at least one removable adapter fitting for fluidly connecting the outflow portion of the accessory to the air inlet of the aforementioned nebuliser device, so as to generate a suction air flow from the suction orifice to the outflow portion.

By means of the above technical solution, the compressor of the nebuliser device, which is in fluid connection with said accessory, continuously applies a suction pressure, thus ensuring an effective removal of mucus from the upper respiratory tract of the patient by the accessory.

Preferably, the mucus removal attachment comprises means for regulating the air flow entering from an inhalation aperture of the mouthpiece, preferably a control opening, which may be partially and/or fully closed, which is fluidly connected between the outflow and the inhalation aperture.

By controlling the opening, the size of the air flow into the suction nozzle can be manually adjusted, so that the suction capacity of the mucus can be quickly, effectively and controlled without stopping the sprayer device.

More preferably, the control opening is manually closable and is dimensioned and/or shaped such that the air passage between the control opening and said outflow portion has a smaller flow resistance than the air passage between the control opening and the nozzle suction hole. In this way, the suction force of the air flow through the suction aperture of the suction nozzle can be controlled simply by the operator's finger closing or releasing the control opening.

In one embodiment of the invention, the means for retaining mucus comprise a device which is located between the outflow portion of the mouthpiece and the suction opening and which is impermeable to mucus and through which air can pass, preferably such means consist of a removable filter which is located between the above-mentioned control opening and the suction opening of the mouthpiece.

The accessory further comprises a grip body, in which the above-mentioned outflow portion is formed, on which a suction nozzle is removably mounted, fluidly connecting the outflow portion with the air inlet of the sprayer device by means of a flexible conduit using an adapter fitting.

The invention has the advantages that:

1. The device can provide continuous suction airflow so as to effectively remove possible mucus in the upper respiratory tract of a patient, and the flow rate of the airflow is adjustable;

2. The setting mode and the setting position of the control opening ensure that a user can conveniently control whether suction is performed or not, firstly, when the control opening is opened, suction airflow enters from the branch of the control opening, namely, suction force only exists at the branch of the control opening, and after a patient inserts the suction nozzle 14 into a nostril, the patient controls the control opening to be closed, so that the suction airflow enters from the air suction port 15, namely, the air suction port 15 generates suction force, thereby sucking mucus, and simultaneously, the flow can be conveniently controlled and the suction force can be adjusted. In such a way, the problem that the suction nozzle is inserted into the nostril of the patient firstly and then the compressor is started in the prior art, and the patient feels uncomfortable due to the instantaneously generated suction force is solved.

Detailed Description

With reference first to fig. 1 and 2, a conventional nebuliser device 1 is shown, comprising a casing 2, generally made of plastic, on which casing 2 an outlet 3 and an inlet 4 for the flow of compressed air are arranged, the nebuliser device 1 being equipped with an air compressor (not shown).

An air compressor is fluidly connected to the air inlet 4 and the outlet 3 in a prior art connection to draw air from the suction nozzle 4 and deliver an air stream to the outlet 3. The compressor may be an impeller type compressor equipped with a piston and driven by an electric motor, the start and stop of which is controlled by a switch 6.

In addition, as shown in fig. 1 and 2, in the atomizer device 1, since a piston type compressor is used, the output port 3 and the intake port 4 are arranged at positions adjacent to each other on the housing 2.

Furthermore, in the sprayer device 1 of the invention, the air inlet 4 may be partially covered by a plug 5, the plug 5 being of a type known in the art, the plug 5 covering the air inlet 4 in a removable manner, the plug 5 having an air-permeable filter for preventing dust or other harmful substances from entering the compressor.

in addition, the plug 5 can also take different configurations, for example consisting of a simple removable cage carrying the above-mentioned air-permeable filter, even without the presence of filtering means.

As shown in fig. 2, removal of the plug 5 in the sprayer device 1 enables complete uncovering of the aforementioned air inlet 4.

According to one aspect of the invention, the nebulizer device 1 may comprise one or more accessories 20 for nebulizing a medicament, the accessories 20 comprising a prior art nebulizer 23, the nebulizer 23 being provided with a nebulizing nosepiece, the medicament to be nebulized being placed on the nebulizer 23. Wherein the snout is typically removable (not shown) for contacting the nose or mouth of a patient for inhalation of the aerosolized medicament.

The snout of the nebulizer 23 may be fluidly connected to the output port 3 of the nebulizer device 1 by a flexible conduit 22 and a connector 21, wherein the connector 21 engages with the output port 3. Typically, the connector 21 is removably connected to the outlet 3 for replacement or removal from the sprayer device 1 when not in use.

the attachment 20 for nebulization and delivery of a drug in combination with the nebulizer device 1 may constitute a system 100 for medical treatment of the respiratory tract, which attachment may be of a type known in the art.

In one embodiment, as shown in fig. 3 to 7, the system 100 further comprises an attachment 10 for removing mucus, the attachment 10 comprising a mouthpiece 14 adapted to be partially inserted into a nostril of a patient, and a grip body 13, the grip body 13 being detachably connectable to the mouthpiece 14, a flexible conduit 12 and an adapter fitting 17, the adapter fitting 17 being adapted to fluidly connect the attachment 10 to the air inlet 4 of the nebulizer device 1.

Preferably, the nozzle 14 is tapered and is removably connected to the above-mentioned grip body 13 by means of an insertion or screw connection.

As shown, the conical top portion of the suction nozzle 14 has a suction aperture 15, which suction aperture 15 is fluidly connected to an outflow portion 16 by an internal suction path, which outflow portion 16 is arranged at an end of the grip body 13 remote from the detachable suction nozzle 14.

By means of the above-mentioned conduit 12, the outflow portion 16 is fluidly connected with the adapter fitting 17 (removing the above-mentioned plug 5 if necessary), and the adapter fitting 17 is engaged with the air inlet 4 of the nebulizer device 1, in such a way that the air inlet 4 is fluidly connected with the outflow portion 16.

In this way, when the compressor of the nebuliser device 1 is operated, the suction air flow generated at the air inlet 4 causes the air to flow out from the suction hole 15 of the mouthpiece 14 through the outflow portion 16 of the grip body 13, so as to cause an effective suction, removal of possible mucus in the upper respiratory tract of the patient.

In addition, the mouthpiece 14 may take other shapes so long as it is capable of engaging (even partially) one or both nostrils to remove mucus from the upper airway of a patient.

In the present embodiment of the attachment 10, the adapter fitting 17 is arranged on the monolithic body 11, the monolithic body 11 also comprising a diffuser cap 18, sized and shaped to be fluidly connectable to the outlet 3 of the nebulizer device 1, for adjusting the direction and/or the manner of diffusion of the air flow exiting from said outlet 3. When the compressor of the nebuliser device 1 is in operation, the air sucked in through the air inlet 4 is dispersed by the diffuser cap 18, after having compressed and flown out from the outlet 3, in such a way as to avoid the flow of air from interfering with the patient and from feeling uncomfortable to the patient.

In addition, in an alternative embodiment of the invention, the diffuser plug 18 to be applied to the outlet port 3 and the adapter fitting 17 to be connected to the air inlet port 4 of the atomizer device 1 may also be manufactured separately.

Preferably, means for retaining or restricting the mucus are mounted in a known manner in the mouthpiece 14, for example constituted by a filter that does not allow the passage of mucus and at least partially allows the passage of air, or by a reservoir or labyrinth, or other means suitable for preventing mucus from being sucked into the nebuliser device 1. These mucus retaining means (not shown) are provided in the mouthpiece 14, but also in the grip body 13 and/or the adapter fitting 17, as long as they are located in the suction airflow path.

In particular, said filter is interposed between the suction opening 15 of the mouthpiece 14 and the outflow portion 16 of the grip body 13, said filter being permeable to air and impermeable to mucus. Preferably, the filter is arranged in the suction nozzle 14, and can be easily removed for replacement or cleaning by detaching the suction nozzle 14 from the grip body 13.

Preferably, the attachment 10 for removing mucus also comprises means for adjusting the size of the suction air flow entering from the suction hole 15, which means comprise at least one control opening 19, which control opening 19 is provided with a portion that can partially and/or completely close off the fluid from the outside, which portion is fluidly connected between the outflow 16 and the suction hole 15, the suction air flow flowing from the suction hole 15 to the outflow 16.

In other words, the control openings 19 formed on the grip body 13 enable the suction air flow to be distributed along other paths, which air would flow directly from the suction hole 15 to the outflow portion 16 if the control openings 19 were not present.

The control opening 19 also comprises a branch which allows the gas flow generated by the compressor of the nebuliser device 1 to be directly vented to the atmosphere. Preferably, the control opening 19 is dimensioned and/or shaped such that the gas passage between the control opening 19 and the outflow 16 has a smaller flow resistance than the gas passage between the control opening 19 and the suction opening 15. In this way, when the control opening 19 is open, the suction flow generated by the compressor of the nebuliser device 1 is substantially entered by the branch on the control opening 19, passes through the outflow 16 and then reaches the air inlet 4 of the nebuliser device 1, without generating a flow at the air inlet 15 capable of removing the patient's mucus. Conversely, when the control opening 19 is closed, the suction airflow generated by the compressor of the nebuliser device 1 enters through the suction opening 15, passes through the outflow portion 16 and then reaches the air inlet 4, in such a way that mucus present in the nares of the patient can be sucked and removed.

The control opening 19 is of such a size and shape that it can be closed manually, for example by the finger of the patient, and the control opening 19 can be completely closed to establish a path of the inhalation airflow from the inhalation orifice 15 towards the outflow 16, via the conduit 12, the adapter fitting 17, towards the air inlet 4 of the nebuliser device 1, in such a way that mucus in the nares of the patient can be sucked and removed. By using the above-mentioned attachment, the patient can manually and conveniently control the on-off of the suction airflow through the suction hole 15 to suck mucus by the suction airflow.

In the present invention, preferably, the aforementioned mucus retention filter (not shown) is disposed in the suction airflow path between the inhalation orifice 15 and the control opening 19 so that the control opening 19 is not affected by the patient's mucus.

In summary, the system 100 for medical treatment of the respiratory tract according to the present invention may comprise a nebulizer device 1 and an attachment 10 for mucus removal, said attachment 10 being connectable to an air inlet 4 of said nebulizer device 1, while the system 100 may further comprise one or more attachments for nebulization of a drug, such as an attachment 20 for nebulization of a drug, which attachment is connected to an output 3 of the nebulizer device 1.

Preferably, the nebulizer device 1 of the system 100 for medical treatment of the respiratory tract comprises an output port 3 and an inlet port 4, wherein, using a piston-type air compressor, the output port 3 and the inlet port 4 are arranged adjacent to each other on the housing 2 of the nebulizer device 1; preferably, the diffuser cover 18 and the adapter fitting 17 are detachably connectable to the outlet port 3 and the inlet port 4, respectively, and the outlet port 3 and the inlet port 4 may be formed on the unitary body 11 connected to the mucus removal attachment 10. Preferably, in the system 100, the air intake 4 is protected by a removable plug 5, known in the art, which is able to allow sufficient air to flow into the compressor, and the plug 5 comprises an air filter able to prevent dust or other harmful substances from entering the compressor.

In the present invention, when the system 100 is used for medical treatment of the upper respiratory tract, it generally comprises the following steps:

a) Connecting a mucus removal fitting 10 of the type described above to the air inlet 4 of the nebuliser device 1 by means of an adapter fitting 17;

b) The mouthpiece 14 is then applied to at least one nostril of the patient;

c) The compressor of the atomizer device 1 is started.

in this way, the suction airflow generated by the compressor of the nebulizer device 1 acts at the suction opening 15 of the mouthpiece 14, and mucus is removed from the nares of the patient by means of the suction airflow at the suction opening 15.

Preferably, the method of the system 100 for treating the upper respiratory tract comprises the steps of:

Removing the above-mentioned removable plug 5 for protecting the air inlet 4 of the nebuliser device 1 and, if necessary, also the accessory 20 for nebulising the drug, the corresponding connector 21 being detached at the outlet 3 of the nebuliser device 1.

Inserting or otherwise engaging the adapter fitting 17 of the attachment 10 for removing mucus with the air inlet 4 of the nebulizer device 1. At the same time, optionally, a diffuser cap 18 is inserted or engaged within the output port 3 of the atomizer device 1. In the case where the adapter fitting 17 and the diffuser cover 18 are made on the integrated body 11, the connection of the adapter fitting 17 and the diffuser cover 18 to the output port 3 and the intake port 4 can be achieved simultaneously.

Inserting the mouthpiece 14 into one or both nostrils of the patient, turning on the compressor of the nebuliser device 1.

Then, by means of the above-mentioned regulating means, the flow rate at the suction opening is regulated. In the case of an adjustment device comprising the above-mentioned control opening 19, the control opening 19 is kept open during operation of the compressor of the nebulizer device 1, after insertion of the suction nozzle 14 into one or more nostrils of the patient, this control opening 19 is then closed by the patient's finger in order to generate a suction flow from the suction opening 15 into the suction nozzle 14. By means of the above-mentioned means for regulating the suction flow, it is possible to easily introduce the suction flow from the control opening 19 (which does not affect the patient's nares) or from the suction opening 15 located in the patient's nares, in order to suck mucous from the patient's nares and to confine it to the mucous retaining means constituted by the above-mentioned filter, which is permeable to air and impermeable to mucous. The control opening 19 may also be partially blocked to allow the user to adjust the amount of suction applied to the nares as desired.
