Description

Description

Title of the invention: Nasal collection device

The present invention relates to a device designed to administer and withdraw a washing fluid, loaded or not with substances, in the ENT sphere.

It is intended for hygiene, irrigation, the collection and biological analysis of samples as well as the treatment and care of the nasal cavities, and more particularly to declutter those of the young child or a person. handicapped by acting as a fly-irrigator baby.

The buildup of phlegm in a child's nasal cavity is problematic because it prevents them from breathing normally (this is especially true for babies under one year old who cannot breathe through their mouths). In addition, their stagnation promotes bacterial proliferation with the risk of contamination spread to the entire ENT sphere (otitis for example).

The evacuation of phlegm in young children up to three years old, an age when they have generally acquired autonomy in the gesture of blowing their nose, can be carried out with a baby nose device. The treatment consists in generating a depression in a nostril in order to extract the phlegm that impedes the respiratory flow.

There are different types of nasal aspirators:

the nasal aspirator by oral suction, comprising a pipe connected to the user's mouth, a nasal nozzle and a reservoir intended to collect the phlegm extracted from the nostril under the effect of the user's suction. It may also include a filter to prevent the passage of phlegm in the suction pipe.

- the deformable pear nose-nose device. After deformation by the user, the return to position of an elastic element generates a suction in order to extract the phlegm and collect it in a reservoir.

- the electric baby nose device which, by means of an electric pump, generates a vacuum allowing the phlegm to collect in a reservoir.

These devices are widely used, however it must be recognized that in the event of severe obstruction or dry phlegm, the result is not always there. In addition, too frequent use of a suction device without moistening the nasal cavities leads to their irritation. For this reason, aspiration into the nostril is often preceded by spraying or instillation of physiological serum, which however requires successively introducing into each nostril the tip of the bottle, then the suction tip. , operations which take time and contribute to the nervousness of the child.

The administration of a liquid in one nostril and its aspiration by the other is a therapy known under the name of "method of displacement of Proetz" and consists in administering in a first nostril the liquid with a pipette held in one hand and then to take it in the second nostril by means of an electric suction source held in the other hand and generally slaved to a foot control. The treatment requires a lot of precautions on the part of the user because it is essential, under penalty of serious trauma, to control the value of the depression applied in the ENT sphere of the patient. In addition, for depression to develop, it is necessary for the patient to keep the soft palate tight (for example by pronouncing the phoneme "KéKéKé"), thus isolating the nasopharynx from the throat. Therefore, this method is not applicable to children under 4 years old, or to disabled people, unable to voluntarily block their soft palate.

Various documents describe devices for irrigating both nostrils simultaneously.

Document GB 178630 describes an administration device comprising, connected to a common reservoir:

-A means of administration, connectable in a leaktight manner to a user's nostril and capable of containing a liquid and,

-A sampling means, which can be connected in a sealed manner to the user's second nostril,

-A means of input connected to the user's mouth.

With this device, the liquid solution is administered into one nostril by the action of pressure delivered by the user's breath, and its excess reaching the other nostril returns to the reservoir through the withdrawal means. The act of blowing automatically closes the soft palate so that the liquid does not pass into the throat. The device therefore operates without aspiration and in a closed circuit, which results in obtaining a sample flow rate identical to the administration flow rate and, moreover, subordinate to the latter.

It is however impossible to apply such a device to a baby or to a disabled person, since in the inability to blow voluntarily or to close the soft palate. Document EP 2389918 filed in the name of the applicant as well as patent FR 3 016 125 A1 describe a device administering a liquid in a first nostril while withdrawing it by the other thanks to the mobilization of a separation means which can be constituted by the plunger of a syringe or by a deformable membrane. This device operates in a closed circuit, without an external suction source, which makes it possible, through a phenomenon of surface tension, to limit the penetration of liquid into the throat, in particular in children, on the condition, however, of having a seal. perfect for the nostrils, which is not always easy to achieve if the child struggles. In addition, the administration of liquid is subject to a transfer of fluid into the sampling means, which deprives the user of the possibility of administering the liquid and then of suspending the operation during the aspiration phase.

Document FR 2 960423 A1 describes a device designed to administer a liquid into the nasal cavity through an element configured to produce an interactive mechanical movement between an administration circuit and that of sampling.

As the administration and aspiration flows are linked, the device does not allow autonomous fluid administration.

Document FR 2297032 A1 describes a device designed to clean and disinfect the nasal cavity comprising a suction-pressure pump making it possible to circulate a liquid in the ENT sphere in a closed circuit.

The device thus presented does not make it possible to have an administration flow independent of that of aspiration.

The applicant's approach was therefore to reconsider the traditional methods of unblocking or collection for nasal purposes and to find out whether it would be possible to obtain a device making it possible to irrigate and extract the elements present in the two nasal cavities at both by allowing a user to control each of the flow rates independently, with one hand, in particular to be able to be used by a single operator, the two operations occurring simultaneously or staggered in time, while avoiding the penetration of liquid into the back throat whatever the position of the patient's head.

This is what the invention proposes, using the known means, namely:

a sampling means comprising a collection reservoir intended for the collection of fluid and provided at one end with a nasal sampling nozzle intended to be connected to a first nostril of a patient, and provided by the other end with a suction means configured to establish in the sampling means a suction by means of an electric pump or from that generated by the oral suction of an operator, and comprising a means of control configured to provide said operator with control of the suction flow by mouth or by hand,

a means for administering washing fluid for nasal purposes comprising a reserve filled with washing fluid and provided with a nasal administration nozzle intended to be connected to the second nostril of the patient, reserve configured to transmit the manual force which is applied to it by the operator, to the washing fluid or to an administration valve designed to contain it under pressure, and to administer said washing fluid according to a flow independent of that present in the sampling means.

The nasal collection device according to the invention further comprises a connecting means designed to mechanically secure the administration means with the sampling means and provide a position of one relative to the other such as the distance between the longitudinal axes of the mouthpieces corresponds to the distance between the two nostrils of the patient and that the control means occupy a location accessible to the operator's mouth or to at least one of the fingers of the hand exerting a force on the reserve, so as to allow it, when the nasal tips are each placed in the patient's nose, to administer the washing fluid therein while controlling the suction flow in the sampling means.

Thus, the user can, with one hand, perform a complete care of the nasal cavities of the patient while controlling the administration of washing fluid and its withdrawal, the two operations, whose flows are independent, occurring simultaneously or not. . It is also advantageous to be able to use the device regardless of the position of the patient's head, the treatment thus being able to be carried out equally well in a lying or sitting position. The device, by simultaneous aspiration, prevents the penetration of liquid into the throat and therefore makes the operation less traumatic for the patient, thus facilitating its repetition.

In an alternative embodiment, the device comprises a pipe and a mouthpiece so that the operator can generate a mouth suction. The device thus does not require any energy source other than that supplied by the user. In addition, oral suction is particularly well suited here because it makes it possible to generate a controlled air flow with a high peak flow rate, while remaining within vacuum values that are not dangerous for the patient.

In another configuration, the suction is provided by an electric pump. Thus the user is dispensed from sucking into the device, the operation which can sometimes be inconvenient. This configuration also makes it possible to perform, in adults, operations for the evacuation of bodily elements, such as scabs, in particular in the case of post-surgical care. In an alternative embodiment, the connecting means is configured to provide a removable and stable mechanical connection with the reserve. Thus, the device is particularly suited to the use of consumables already present on the market, nasal spray or single-dose single-use pipette, by providing for their rapid and easy installation.

In one embodiment of the invention, the device comprises at least one reserve elastically deformable by pressure or a manual force applied transversely, such as a single-dose pipette initially filled with liquid. Thus, the liquid contained in the pipette is administered directly into the nostril, and a previously used pipette acts as a disposable collection reservoir.

In an alternative embodiment, the administration means consists of a nasal spray, with a manual pump or comprising a pressurized liquid reserve associated with an administration valve actuated by pressing on a nasal nozzle forming a spray head. This configuration allows the use of an accessory already available on the market and designed to perform numerous liquid administrations without replacement intervention.

In one embodiment of the invention, the electric pump is controlled by the air flow coming from the operator's mouth, thus offering him the possibility of controlling the suction flow in the sampling means by blowing or by aspiring.

In a preferred embodiment of the invention, a pressurized type nasal spray is associated with an electric baby nasal aspirator, thus offering the operator the possibility of jointly using two autonomous devices and of combining their action to obtain a electrical device allowing the operator to control the flow of administration of the washing fluid and that of its sample with one hand,

FIG. 1 shows the device consisting of an administration means 100, a sampling means 200 and a connection means 300.

The administration means 100 consists of an administration reserve 101, deformable by force or manual pressure and capable of containing a washing fluid 103, loaded or not with treatment substances, for example a liquid such as physiological serum, thermal water or sea water, reserve 101 connected in its upper part to a nostril of the beneficiary of the treatment by an administration duct 102 provided at its end with a nasal administration nozzle 110 , preferably flexible and deformable. The reserve 101, advantageously of viscoelastic material, comprises lateral bellows, to facilitate its axial deformation, associated with a deformation element 302, located at its base and made of a non-deformable material.

The sampling means 200 comprises a collection reservoir 201 connected to the other nostril of the patient by means of a sampling duct 202 provided at its end with a nasal sampling nozzle 210, preferably flexible and deformable and suitable. to be connected in a waterproof manner. The collection reservoir 201 accommodates in its lower part a shutter 203 intended to provide a tight closure, the said shutter 203 comprising a suction duct 204 capable of containing a filtration means 205, for example a cellular foam. A suction means 220 makes it possible to establish a suction in the sampling means 200 from the suction generated by the operator's breathing circuit, in this case the mouth. It consists of a connector 221 in sealed connection at one end with the lower part of the suction duct 204, for example by clamping, and connected by the second end to a suction pipe 222 itself connected to a means of control 223, such as a mouthpiece, intended to be connected to the mouth of the operator or that of the recipient of the treatment. Way to control 223 allows the user to generate and control through the mouth the suction flow present in the sampling means 200.

The connecting means 300 provides an integral assembly of the administration means 100 and the sampling means 200 by associating in an orientable and removable manner two connecting elements 301 by means of an articulation means 310, in order to unite and immobilize by adjustment the two conduits 102 and 202, so that, when the nasal sampling nozzle 210 is positioned in a sealed manner in a first nostril of a patient, the position of the administration nozzle 110 is at the same time. entry of the second nostril. Thus the distance between the longitudinal axes of the two nasal attachments 110 and 210 corresponds to the distance between the two nostrils of the patient, or by way of example a distance between 8 and 20 mm In order to facilitate the positioning of the nasal attachments 110 and 210 in the nostrils of the patient, the articulation means 310, for example a pivot connection of the ball-and-socket type, is configured to provide an angle α of inclination between the two longitudinal axes of said nasal tips of between 0 ° and 120 °. The articulation means 310 provides a removable but stable connection by suitable tightening with each connecting element 301 allowing the operator to manually orient the administration means 100 relative to the sampling means 200 while ensuring the stability of the position thus acquired. The connecting means 300, and in particular the connecting element 301 located near the nasal administration nozzle 110, provides a bearing surface making it possible to ensure the position of two fingers (index and middle finger) and their support while the thumb of the same hand is positioned on the bottom of the reserve 101, on the handling element 302. The connecting means 300, through each connecting element 301 secures and positions the means 100 and 200 relative to each other, and therefore provides a location of the reserve 101 relative to the control means 223 at a distance D and an orientation corresponding to those of the hand of the operator relative to his mouth. so that when he holds the reserve 101 in one hand, the control means 223 occupies a position accessible to his mouth. By virtue of its length, the suction pipe 222 is able to provide a position of the control means 223 relative to the reserve 101 corresponding at most to the distance between the operator's mouth and that of his hand when the arm is stretched, or as an indication a distance between 1 mm and 100 cm.

The connecting means 300, by design, provides a nasal-sighted collection device comprising a free space around the reserve 101 and provides a bearing area on said reserve 101 accessible to at least one finger of the hand of the patient. the user so that he can exert a manual force in order to deform it and to administer the washing fluid 103. The connecting means is designed to mechanically combine the administration means 100 and the sampling means 200 while ensuring their autonomy from a fluidic point of view. The flow of administration in the administration means 100 is consequently independent of that of aspiration in the sampling means 200 and vice versa.

After filling the reserve 101 with the appropriate washing fluid 103 and keeping the patient in a favorable position with his arm or his free hand in the case of pediatric use, the operator positions his other hand on the device, thumb on the deformation element 302, index and middle finger on the connecting element 301, similarly to the positioning of the fingers on a syringe. The control means 223 held between the lips, it then places the nasal sampling nozzle 210 in a sealed manner in one nostril of the patient as well as the nasal administration nozzle 110 in the other, without any other external support. The manual force applied by the operator on the reserve 101 deforms it and is transmitted to the washing fluid 103 for administration into the corresponding nostril. Simultaneously or after having suspended his delivery, the operator generates a suction flow in the sampling means 200 by a buccal suction applied to the suction means 220 through the control means 223 in order to collect the washing fluid 103 in the collection reservoir 201, possibly loaded with mucus coming from the nasal cavities, this without having to change the position of his fingers on the device. He can start the treatment again at will without changing his position. It also has the possibility of precisely dosing the flow rate and the quantity of the washing fluid 103 administered by varying the manual force exerted on the reserve 101, separately or simultaneously with the suction, the flow of administration of the liquid being independent. that of aspiration and vice versa. The operator, by modulating the force of the suction generated by his respiratory system, controls with his mouth and by means of the control means 223, the suction flow in the sampling means 200 to adapt it to the treatment.

If the sample flow is sufficient, the treatment is effective regardless of the position of the patient's head because by opposing the gravity of the washing fluid 103, it prevents it from entering the throat. Maintaining suction after the administration phase allows the residual liquid corresponding to the volume of the nasal cavity to be evacuated.

Another embodiment is illustrated by FIG. 2 in which the administration means 100 is a reserve constituted by a single-use pipette of the single-dose pipette type, of design otherwise well known, forming both the reserve 101 and the nasal administration nozzle 110, a pipette that can be elastically deformed by a force or a manual pressure applied transversely to its walls, that is to say according to a force whose main component is perpendicular to the axis of its reserve, and sterile pre-filled with wash 103 to be administered. The collection reservoir 201 also consists of a single-dose pipette, used beforehand and the orifice of which has been enlarged, for example by cutting or by the introduction of a rod of greater diameter, in order to facilitate the passage of phlegm. The suction duct 204 comprises a sealing means 208 capable of perforating the bottom of the collection reservoir 201 (the single-dose pipette), such as a trocar, and capable of providing a sealed connection with the latter. The filtration means 205 is positioned in the suction duct 204, the latter being closed by the shutter 203. The latter is a part resulting from plastic injection also comprising the connector 221 itself connected in a sealed manner to the pipe. suction 222 and by means of control 223, here a mouthpiece.

The connecting means 300, advantageously in one piece and made of viscoelastic material, comprises two holding elements 305, such as clip-on pliers, clips resulting from molding, rings or elastic rings, capable of providing a mechanical connection, advantageously removable, with each means 100 and 200, by means, in this configuration, respectively of the reserve 101 and of the collection reservoir 201 in order to be able to put them in place or take them out while keeping them integral with said connecting means 300 during the treatment. The latter also comprises a stop element 306 configured here to block the translation of the sampling means 200. It will be noted that the holding elements 305 are also designed to provide a mechanical connection ensuring mobility between the two means 100 and 200 in order to varying their respective position, and consequently that of the reserve 101, for example by sliding, while offering, by sufficiently firm tightening, a maintenance and stability of the position once this has been obtained. The nasal-sighted collection device thus arranged provides a free space around the deformable wall of the reserve 101 accessible to at least one finger of the operator so that he can exert a manual force and deform it.

The operator uncovers the single-dose pipette constituting the reserve 101, inserts it into the connecting means 300, after having taken care to install a single-dose pipette, empty, on the suction pipe 204 in the 'pressing downwards so that its lower part is pierced by the sealing means 208. By a force or a manual pressure controlled and applied transversely on the reserve 101, it deforms it. The force or manual pressure is thus transmitted to the washing fluid 103 to be administered into the patient's nostril and to carry out the treatment as described above.

The retaining element 305 is made of a viscoelastic material giving it mechanical characteristics, and particularly elastic properties, making it possible to ensure the transfer of the manual force which is applied to it by the operator on the reserve 101. Its shape is adapted. to that of reserve 101. In an alternative embodiment not shown, the holding element 305 which allows the positioning of the reserve 101 takes the form of a clamp comprising at the base of at least one of its branches a transverse zone of lesser thickness. giving it characteristics and mechanical properties of suppleness and flexibility. As before, the retainer 305 is designed to provide the transfer of manual force from the operator to the reserve 101.

It will be noted that the connecting means 300 by its arrangement provides a bearing surface or gives access to a bearing zone on the reserve 101 allowing the operator to hold and use the device only with two fingers of the same hand.

He can hold the device by positioning a finger on the connecting means 300, in this case one of the holding elements 305, and simultaneously press the reserve 101 with a second finger of the same hand. Thus, the connecting means 300 comprises a support surface accessible to at least one finger of the operator's hand exerting a force on the reserve 101.

He can also hold and operate the device by positioning two fingers of the same hand on the retaining element 305, the latter providing, by virtue of its elastic properties, the maintenance of the administration means 100 by means of the reserve. 101 as well as the transfer of force or manual pressure from the operator.

In a non-illustrated embodiment, the retaining element 305 takes the form of a ring, a sleeve, a collar or a ring made of viscoelastic material configured to be positioned on the. nasal administration nozzle 110, the nasal sampling nozzle 210 or the reserve 101. The retaining element 305, by virtue of its elastic properties or its adapted dimensions, provides a tightening ensuring the maintenance of the sampling means 200 by the through the nasal sampling nozzle 210 or the collection reservoir 201 and that of the administration means 100 through the nasal nozzle 110 or the reserve 101. D can thus adapt to various nozzle profiles nasal administration or reserve models. The mechanical connection obtained allows the adjustment of the position between the means 100 and 200 by allowing the sliding and the rotation of each nose piece and / or of the reserve 101.

In a non-illustrated variant of the previous embodiment, the retaining element 305 takes the form of a cap, a collar or a sleeve forming, by virtue of their elastic properties, a sealing means. The retainer 305 is configured to provide a contact surface with the nose to provide or reinforce the seal at the nostril when positioned on the nasal administration nozzle 100 or the sample. 200, especially when using a single-use pipette with sometimes aggressive tips. Advantageously, the retaining element 305 forms a flexible, elastic and deformable nose piece which maintains and covers, at least in part, the nose piece 110 or 210 or even the reserve 101 while also providing a sealed mechanical connection with these elements.

FIG. 3 illustrates a configuration in which the administration reserve 101, such as a syringe body, allows the movement of a mobilization means 150 capable of generating the transfer of the washing fluid 103 into the administration means 100. The mobilization means 150 is constituted by a piston 155 integrally linked to a rod 152 sliding in a bearing 151 formed in the lower part of the reserve 101 for guiding purposes, the said mobilization means 150 having, in order to be actuated, d a handling element 153 intended to allow the support of the thumb.

A nozzle 104, such as a nozzle, capable of administering the washing fluid 103 in the form of a spray, droplets or fine jets, is positioned in the administration duct 102, advantageously close to the nasal administration nozzle 110. The administration means 100 is therefore in the form of a syringe, advantageously pre-filled with the washing fluid 103.

The operator exerts a manual force on the handling element 153 to transmit it to the washing fluid 103 and thus administer the latter in the form of fine droplets in order to be able to remove it, possibly in association with phlegm, by oral suction via the means control 223.

Depending on the diameter of the nozzle 104, the mobilization means 150, identical to a syringe, makes it possible to aspirate the washing fluid 103 through the nasal administration nozzle 110, from an annex container , to then deliver it to the patient. It thus makes it possible to establish the transfer of the washing fluid 103 into the administration means 100, either by suction or by administration.

FIG. 4 illustrates an embodiment in which the administration means 100 consists of a device capable of delivering the washing fluid 103 contained in the reserve 101 in the form of spray, droplets or fine jets, such as a spray nasal pump with mechanical pump. This is a mechanical device comprising a mechanical pump actuated by manual pressure and configured to deliver the washing fluid 103 when a manual force is exerted simultaneously on the reserve 101 and the nasal administration nozzle 110, the latter also doing as a spray head. These devices are of a design known elsewhere and in widespread use. These therefore comprise a nasal administration nozzle 110 forming the spray head and optionally comprising a nozzle 104, a mechanical pump comprising valves and springs and a reserve 101 filled with the washing fluid 103.

The connecting element 300 comprises an orifice 307 adapted to allow the passage and to maintain by adjustment the nasal administration piece 110. The orifice 307 provides a rotary connection with the nasal administration piece 110 and therefore with the administration means 100 relative to the connecting means 300, and allows, by the fact, to modify the spatial position of the sampling means 200 relative to that of the administration means 100, as well as that of the nasal nozzle d administration 110 relative to that of the nasal sampling nozzle 210. The administration means 100 is positioned either to the right or to the left of the sampling means 200 in order to be used by a right-handed or left-handed operator.

The connecting means 300 comprises a connecting element 301 configured to take a shape and keep it in order to modify and maintain the position of the two means 100 and 200, and consequently of the two nose pieces 110 and 210, one relative to the other. To achieve this, it consists of a strip comprising two metal wires incorporated into a viscoelastic material, the whole thus giving it a shape memory. It has mechanical characteristics giving it the ability to be deformed by the user, manually and without the aid of tools, while maintaining the position thus obtained throughout the treatment.

The connecting means 300 also comprises a support element 308 positioned on the connecting element 301, on the periphery of the nasal administration nozzle 110, configured to provide a support zone intended for positioning and support. at least one finger of the operator's hand exerting a force on the reserve 101, in this case the index and / or middle finger in this configuration. The support element 308 is advantageously made of a viscoelastic material intended to improve the adhesion of the support.

After having deformed the connecting means 300 to their liking, the user positions the two means 100 and 200 and more particularly the two nasal tips 110 and 210 so that they adapt well to the patient's nostrils. It positions the index and middle fingers on the support element 308, integral with the nasal administration nozzle 110, and it exerts a manual force, opposite to that exerted by the index and middle fingers, through of his thumb on the lower part of the reserve 101, which has the effect of actuating the mechanical pump of the nasal spray and of delivering a dose of washing fluid 103 in the form of droplets or fine jets. FIG. 5 illustrates a variant of the previous configuration in which the administration means 100 is a nasal spray of the pressurized type, comprising a reserve 101, generally made with a metallic material, capable of containing the washing fluid 103 initially packaged under pressure. , and cooperating with an administration valve 120 configured to contain said washing fluid 103 under pressure and to administer it when actuated by the manual force of the operator exerted on both the nasal administration nozzle 110, constituting the spray head and possibly including a nozzle 104, and against the reserve 101. These devices are of design known elsewhere and in widespread use.

The connecting means 300 consists of two holding elements 305, for example two clamps of the clip type, assembled head to tail and intended to removably hold, by suitable clamping, the administration means 100 by means of the nasal nozzle 110 and that of sampling 200 by means of the collection reservoir 201. The two holding elements 305, and consequently the connecting means 300, advantageously form one and the same part resulting from the molding. Depending on whether he is right-handed or left-handed, the operator will position the sampling means 200 to the left or to the right of the administration means 100. The operator positions the reserve 101 in one hand and squeezes it between his palm and at least one. finger, while placing another finger of the same hand, the index or middle finger preferably, resting on the nasal administration nozzle 110. By exerting a manual force against these two support points , it proceeds to the administration of the washing fluid 103.

It will be noted that the connecting means 300 could in the same way be secured to the nasal sampling nozzle 210 by means of a first holding element 305, the second ensuring the holding of the nasal administration nozzle 110 or from reserve 101.

The connecting means 300 may also have the appearance of a single piece or element derived from plastic injection including the nasal administration nozzle 110 and / or the nasal sampling nozzle 210.

As described above, the retaining element 305 may take the form of an elastic ring which is fixed to the nasal administration nozzle 110, in particular to the tubular part of the spray head, or else of a sleeve forming a stop means, such as a preferably elastic collar, providing, when it is positioned on the nasal administration nozzle 110, its covering and thus providing a reinforced seal at the level of the nostril. The retaining element 305 then acts as a “nasal over-nozzle”, allowing hygienic protection of the nasal administration nozzle 110. The stop means provides furthermore, a limitation of the penetration of the nasal administration nozzle 110 inside the nostril in order to avoid any risk of injury.

In a non-illustrated embodiment, the connecting means 300 is formed in part by the nasal sampling nozzle 210. H is designed by a single element resulting from plastic injection, made with a viscoelastic material, comprising both l The sampling tip 210 and the retainer 305. The latter, for example a sleeve, is configured to be positioned on the nasal administration tip 110, particularly on the end of the spray head of a spray. nasal of the pressurized type as described above, or on that of an elastically deformable disposable pipette, while ensuring their maintenance. In the case of the pipette, the connecting means 300 provides, by virtue of its elastic properties, the covering and maintenance, at least in part, of the reserve 101 since it coincides with the nasal administration nozzle 110, optionally in a sealed connection. . The nasal sampling nozzle 210 is connected to the collection reservoir 201, which in turn is connected to a mouthpiece through a suction tube. The connecting means 300 thus provides a simple assembly between an existing liquid administration device and the reservoir for collecting a baby fly by oral suction.

Figure 6 illustrates a configuration in which the suction is generated by a suction means 220 consisting of a body 228 housing an electric pump 224 powered by a power source 229, such as batteries. The electric pump 224 has in its upper part a suction pipe 222 intended to be connected to the connector 221. The electric pump 224 also has a discharge channel 226, lateral, opening to the free air. The suction means 220 also comprises a control means 223, for example a control element such as an electrical contact switch of the push type, intended to provide the operator with control of the suction flow by controlling the pressure. power supply to the electric pump and configured to operate the starting or stopping of the electric pump 224 by establishing or interrupting the electrical connection with the energy source 229. The suction means 220 is of a design that is otherwise well known , and advantageously, it corresponds to an electric baby fly pump capable of generating a pneumatic depression, limited to -500 mb in order to avoid possible barotrauma.

The connecting means 300 is integrally assembled by any suitable fixing element on the upper part of the suction means 220. Advantageously, it forms an integral part of the body 228. It is also able to securely hold the means. administration 100 through the base of the reserve 101 and the sampling means 200 through the shutter 203, the assembly thus formed constituting a device holding in one hand. the control means 223 is positioned relative to the reserve 101 at a distance D and an orientation such that its location is accessible to at least one finger of G user, for example the index or middle finger, while another of the same hand, for example the thumb exerts a force on the reserve 101. As an indication, the distance D between the reserve 101 and the control means 223 is between 1 mm and 20 cm, spacing corresponding to the maximum spacing between the thumb and the tip of the middle finger. Thus, the user controls with one hand the suction flow that he can establish in the sampling means 200 at any time of the treatment, simultaneously or separately from the administration of liquid, the suction flow being independent of that of administration and vice versa.

FIG. 7 illustrates a variant of the previous configuration in which the suction means 220 comprises a means for detecting the flow 230, such as a flow or pressure sensor, configured to control an electrical contact as a function of the air flow or of the pneumatic pressure applied to it. The flow detection means 230 is connected to the control means 223, such as a mouthpiece, via a detection pipe 227. The position occupied by the control means 223 with respect to the reserve 101 corresponds to a location accessible to the operator's mouth when one of his hands is resting on the reserve 101. The electrical contact of the flow detection means 230 is connected to the electric pump 224.

When the operator sucks in or blows through the control means 223 positioned between his lips, he generates an air flow in the detection pipe 227 and controls, via the flow detection means 230, the control of the pump 224. The latter, by being slaved to the air flow produced by the operator, establishes a suction flow in the sampling means 200.

FIG. 8 illustrates a preferred embodiment of the invention in which the administration means 100 consists of a pressurized type nasal spray comprising a nasal administration nozzle 110 constituting the spray head and configured to actuate by pressing. manual an administration valve 120 cooperating with a reserve 101 of washing fluid 103 initially packaged under pressure in order to administer it in the form of a spray.

The sampling means 200 comprises a suction means 220 fitted with an electric pump 224 housed in a body 228 and a collection reservoir 201 fitted with a nasal sampling nozzle 210.

The connecting means 300 secures the administration means 100 and the sampling means 200 by providing with each of them a removable connection by means of a holding means 305, for example a clamp made of viscoelastic material endowed with mechanical properties. allowing it to ensure a stable maintenance of the means of administration and collection. One stopping means 306 allows the blocking in translation of the administration means 100 by pressing on the bottom of the reserve 101. The holding means 305 also allows the rotation of the reserve 101, and therefore its orientation, in order to '' more precisely adjust the positioning of the nasal administration nozzle 110. The retaining means 305 is configured to position the nasal administration nozzle 110 in a location accessible to the index or middle finger of the exerting hand. on the reserve 101 and to position the control means 223 in a location accessible to the thumb of the same hand. The control means 223 is therefore positioned on the connecting means 300 in a location such that the nasal administration nozzle 110 is accessible at the distal end of the index or middle finger of the hand exerting a force on the reserve. 101 while the control means 223 is accessible to the thumb of the same hand. As an indication, the distance D between the control means 223 and the nasal administration nozzle 110 is between a few mm and 20 cm.

The operator grasps the collection device thus formed with a single hand positioned simultaneously on the reserve 101 and the connecting means 300 and places the two nasal tips 110 and 210, already suitably oriented by the arrangement of the device, each in one nostril. of the patient. He administers the washing fluid 103 by manual pressure, via the last phalanx of the index or middle finger positioned on the nasal administration nozzle 110 while he places his thumb on the control means 223 to generate a suction in the sampling means 200.

Of course, the connecting means 300 has the possibility of being arranged so that any pair of fingers of the hand exerting a force on the reserve 101 is able to be in contact and to exert a force. simultaneously pressing on the nasal administration nozzle 110 and on the control means 223. The location of the nasal administration nozzle 110 therefore corresponds to that occupied by one of the fingers of the hand exerting a force on the reserve 101 while another of the fingers of this hand is placed on the control means 223.

It emerges from the foregoing that the device according to the invention is intended to facilitate the treatment, and more particularly the irrigation and the extraction of phlegm in a patient, by offering a single operator the possibility of providing complete care of the patients. nasal cavities. It also finds its place in the collection of samples for biological analysis, for example to detect the presence of viruses or bacteria present in the ENT sphere. As the operation takes place at home, it offers an economical approach by limiting the costs associated with travel and protective equipment.
