Description

The present invention relates to an applicator and drinking device for orally administering to a patient a swallowable object, in particular a solid dosage form.

Newly developed methods for diagnosing the upper gastrointestinal tract require the patient - as an alternative to using an endoscope - to simply swallow a small object that is designed as a disposable device designed to collect cells from the lining of the esophagus. This device contains a sponge made of fine mesh with a diameter of about 30 mm, enclosed in a gelatin capsule and attached to a cord or thread. The patient swallows the capsule with water, and the gelatin shell dissolves as soon as the device reaches the stomach. After a few minutes, the healthcare professional uses a cord to remove the expanded sponge. When removed, a slightly abrasive mesh collects cells along the entire length of the esophagus. The collected cells can then be analyzed, for example using immunohistochemical staining, to detect biomarkers that indicate certain diseases.

Although swallowing small objects such as capsules is generally less inconvenient to patients than the use of other diagnostic devices such as endoscopes, it is desirable to make oral administration of such objects as convenient and reliable as possible.

An object of the present invention is to provide an applicator and drinking device that allows oral administration of a swallowable object to a patient in a convenient and reliable manner.

This problem is solved using an applicator and a drinking device according to independent claims of the invention.

According to a first aspect of the invention, an applicator for orally administering to a patient an ingestible object, in particular a solid dosage form, comprises a housing having a first opening and a second opening, the first opening of the housing being configured to connect to a liquid reservoir, in particular a drinking vessel, and the second opening of the housing is designed in such a way that the patient is provided with the opportunity to drink from it. The applicator further includes a holder disposed within the housing and configured to receive an ingestible object, the holder also being configured to allow movement of the ingestible object toward the second housing opening as liquid flows through the housing from the first opening to the second housing opening.

According to a second aspect of the invention, the drinking device comprises an applicator according to the first aspect of the invention and a receptacle, in particular a drinking receptacle, configured to store liquid, wherein the applicator is connected, in particular removably, to the receptacle in such a way that it is possible for the stored liquid to enter in the vessel, into the applicator through the first hole in the body.

Aspects of the invention are based on the approach of placing and/or storing and/or containing an ingestible object or device, which preferably has a shape and/or size, such as a capsule, pill, tablet or pellet, within a preferably sleeve-shaped or tubular body by means of holder located inside the housing. The applicator, in particular the body, is formed and/or sized and/or configured such that it can be connected to and/or attached to a liquid reservoir, such as a drinking vessel, and allows liquid stored in the reservoir to in particular, after or upon tilting the container together with the applicator attached thereto, flow through the housing and/or holder from the first opening to the second opening of the housing. The second opening of the housing is preferably sized and/or shaped, for example, in the form of a spout, a beak-shaped spout or a sippy cup mouthpiece, so that it is convenient for the patient to drink from it. In addition, the holder is preferably designed such that it releases a swallowable object housed therein when the applicator is tilted and/or liquid flows through the housing, and allows the swallowable object to move under the influence of gravity and/or liquid flowing through the housing , to the second opening of the housing, where it comes out of the housing along with the liquid so that the patient can easily swallow it.

The swallowable object preferably is or contains at least one of the following solid or semi-solid dosage forms: tablet, film-coated tablet, capsule tablet, dragee, soft gelatin capsule, hard gelatin capsule, effervescent tablet, pill, powder, granule, pellet, paste, cream, ointment, gel.

The swallowable object or swallowable device is preferably a solid dosage form, such as a capsule, to which a cord and/or thread is attached. The applicator is preferably configured to receive both the object and the cord or thread attached thereto. For example, the cord or thread may be at least partially wound and located within the housing and/or holder, and/or around the holder. Alternatively or in addition, at least a portion of the cord or thread may be wound around the solid dosage form and/or located within the solid dosage form, such as a capsule. In any of the above cases, the applicator and/or holder and/or dosage form is preferably configured to be released from the cord or thread to allow the solid dosage form to be moved by gravity and/or liquid flowing through the body to the second opening, with for the purpose of ingestion by the patient.

Thus, the invention provides convenient and reliable oral administration of swallowable objects, such as solid dosage forms, to a patient.

According to a preferred embodiment, the holder comprises a holder structure which is arranged, in particular coaxially, within the housing and is configured to accommodate a swallowable object. The holder structure preferably includes a lower structure provided at a first end of the holder structure. In addition, preferably the lower structure is configured to allow at least a portion of the liquid that flows through the housing from the first opening to the second housing opening to flow through the holder structure and thereby move the ingestible object to the second housing opening. By means of one or more of the above-mentioned preferred embodiments, the placement of the swallowable object inside the applicator, on the one hand, and the release and movement of the swallowable object to the second opening of the applicator body, on the other hand, are ensured in a particularly reliable and simple manner.

In addition, preferably the lower structure contains and/or is designed in the form of a lattice. The grille preferably has a lattice structure that is smaller than the smallest dimension, eg diameter, of an ingestible object, such that an ingestible object cannot pass through the grille. In this way, it is ensured that a swallowable object placed in the holder and/or resting on the grille cannot pass through the grille and enter a liquid reservoir, such as a drinking container provided at the first opening of the applicator body, with liquid from the reservoir can pass through the grille in the opposite direction and “wash” the ingestible object from the grille to the second opening of the applicator body.

As used herein, the term “grid” or “lattice structure” preferably, but not necessarily, refers to a lattice and/or frame or structure of two or more intersecting strip-like elements. In the simplest case, a lattice or lattice structure can be formed by only two intersecting strip-like elements.

Alternatively or in addition, preferably the bottom structure comprises and/or is implemented as a web, such as a web or strip of the support structure, which is configured to accommodate and/or hold an ingestible object underneath to ensure that the ingestible object resting on a bridge-type bridge or strip, the support structure is suitably prevented from penetrating into the fluid reservoir and is capable of allowing at least a portion of liquid that flows through the housing from the first opening to the second opening of the housing to pass past the bridge-type structure webs or strips of the support structure, respectively, and thereby moving the ingestible object towards the second opening of the housing.

According to another preferred embodiment, the lower structure is mounted on and/or attached to the housing. The lower structure is preferably mounted on or attached to an inner surface of the housing adjacent to the first opening of the housing. In this case, it is also possible to prevent liquid entering the housing and passing through the holder through the lower holder structure from entering the space between the holder structure and the inner surface of the housing. In this way, a thread attached to a swallowable object and stored in the space between the holder structure and the housing can be protected from contact with liquid for as long as possible, so that, for example, the thread only comes into contact with liquid when the object is swallowed by the patient. liquid or shortly before. This is particularly useful, for example, in cases where the thread carries a drug or any other substance intended to be released into the esophagus, since preventing the liquid from coming into contact with the thread too early ensures that the medicine is not washed off the thread before reaching the esophagus.

For example, the lower structure may be provided with a flange with which it is mounted on the housing. Alternatively, the housing and holder and/or lower structure can be manufactured as a single unit using a suitable manufacturing method, such as injection molding or 3D printing.

Furthermore, preferably, the holder structure comprises a wall-like structure which is particularly attached to the lower structure, the wall-like structure having one or more grooves, slots and/or recesses allowing the guidance of a thread or cord which is attached to the swallowable object, placed inside the holder structure, in particular inside the wall-like structure, from the inside of the holder structure or wall-like structure, respectively, to the outer surface of the wall-like structure and/or vice versa, i.e. from the outer surface of the wall-like structure to the inner surface of the wall-like structure, and/or wrap it around the outer surface of the wall-like structure. The holder structure preferably further comprises at least one fixing element, which is in particular provided on the outer surface of the wall-like structure and is configured to fix the thread on the holder structure. For example, the locking element may be or include a protrusion provided on the outer surface of the wall-like structure and shaped and/or sized such that a thread or cord can be knotted thereon. The above embodiments, taken alone or in combination with each other, provide secure placement in the holder of both the ingestible object, such as a dosage form, and the thread or cord attached thereto.

As mentioned above, the cord or thread may not necessarily be wound around the holder or holder structure. Alternatively or in addition, at least a portion of the cord or thread may be wound around a swallowable object, such as a solid dosage form such as a capsule, and/or located within the swallowable object.

According to another preferred embodiment, the applicator further contains and/or includes a swallowable object, in particular a solid dosage form, which is placed in the holder. Alternatively or in addition, the applicator further comprises at least one cap configured to seal the first housing opening and/or the second housing opening, said at least one cap being detachably attached to the first housing opening and/or second housing opening . Before introducing a swallowable object contained in the applicator to the patient, said at least one cap is removed from the housing opening(s). In the above-mentioned embodiments, the applicator also advantageously serves as a primary package for a swallowable object contained therein, in particular a solid dosage form. For hygienic purposes, the applicator may preferably be packaged in additional outer or secondary packaging, such as a plastic bag or box, which may be labeled with, for example, the brand name and/or information regarding the item contained therein and/or instructions for use applicator.

Furthermore, preferably the container has an opening and the applicator is attached, in particular in a detachable and/or detachable manner, to the opening of the container. For example, the vessel may be a conventional drinking vessel, such as a drinking glass or cup, to which the applicator is attached. Alternatively, the container may be a drinking container having a screw cap which is provided with a nozzle or spout to which the applicator is attached, preferably detachable and/or lockable.

As already described above, the swallowable object may preferably be a disposable device which is configured to collect cells from the esophageal mucosa and comprises a fine mesh sponge contained in a gelatin capsule and attached to a cord.

In general, local treatment in the upper gastrointestinal tract is difficult to achieve due to the short esophageal transit time of less than two seconds from the mouth to the stomach. In view of these limitations, it is particularly preferred that the swallowable object comprises a solid dosage form, such as a capsule, pill, tablet or pellet, attached to a thread or cord, which is intended for topical treatment of the esophagus. For example, the thread or cord may contain medicine or any other substance. When a solid dosage form is swallowed, an attached thread or cord, preferably carrying the drug, passes through the esophagus and may remain in the esophagus for a desired period of time, for example to ensure that the drug is released by the thread or cord and delivered to the esophagus.

For purposes of the present invention, the term "thread" preferably, but not necessarily, means thread in the narrower sense, but may also refer to or cover film, also referred to as "plate", "thin strip", "edible film" or "film". oral cavity", which is preferably a thin, flexible and rapidly disintegrating drug carrier which, on contact with saliva, dissolves and releases the active ingredient having a local effect and/or - after absorption - also a systemic effect.

in FIG. 11 a) and b) show, respectively, a front view and a perspective view of another exemplary applicator.

In FIG. 1 is a front cross-sectional view of an exemplary applicator 1. The applicator 1 includes a housing 3, preferably sleeve-shaped and/or axisymmetrically shaped and having a first opening 4 and a second opening 5. Preferably in the area of and/or adjacent to the first opening 4 the housing 3 is formed and/or configured in such a way that it can be, preferably in a liquid-tight manner, connected and/or attached to the upper end and/or opening 23 of a liquid container, in particular a drinking container such as a drinking bottle.

The applicator 1 further includes a holder 6 which is located within the housing 3 and is shaped and/or configured to accommodate and/or store and/or hold a swallowable object 2. The swallowable object 2 is preferably the size and shape of a solid dosage form , such as a capsule. In this example, the swallowable object 2 is held both from below and from the side by the lower structure 9 and the wall-like structure 10 of the holder 6, respectively. Moreover, in this example, a removable cap 8 is attached to the second opening 5 of the housing 3 to seal the second opening 5.

In FIG. 2 is a cross-sectional perspective view of the exemplary applicator 1. As in the example shown in FIG. 1, the second opening 5 of the housing 3 is sealed by a cap 8. However, instead of being attached to the drinking vessel, the first opening 4 is also sealed by a cap 7, which is removably attached to it. The lower structure 9 of the holder 6 is preferably liquid-permeable and can, for example, be made in the form of a lattice or any other liquid-permeable structure.

The body 3 and/or holder 6 preferably has or has a sleeve-shaped or tubular basic shape, and/or the body 3 and/or holder 6 is or is axisymmetric. The holder 6 is preferably located coaxially inside the housing 3, i.e. the symmetry axes of rotation of the holder 6 and the housing 3 coincide.

In FIG. 3 is a perspective view of an exemplary applicator 1 in which the body 3 is sealed by both a lower cap 7 and an upper cap 8.

As can be seen from the examples of FIGS. 2 and 3, the applicator 1 can advantageously serve as a primary packaging for a swallowable object 2 contained therein, in particular a solid dosage form. For hygienic purposes, the applicator 1 may preferably be packaged in additional outer or secondary packaging, such as a plastic bag or box (not shown).

Before introducing the swallowable object 2 contained in the applicator 1 to the patient, the caps 7, 8 are removed from the holes 4, 5, and the body 3 is attached to the hole 23 of the liquid reservoir. This will be explained in more detail below.

In FIG. 4 a)-e) illustrate the exemplary steps of using the applicator 1 in a cross-sectional view.

In the first step shown in FIG. 4a, an applicator 1 is provided containing a swallowable object 2 and sealed with caps 7, 8, as well as a drinking vessel 20. In this example, the drinking vessel 20, filled with a liquid 25 such as water, includes a cup 21 having a threaded connection 22 at its top hole. A screw cap 24 having an opening 23 is screwed onto a threaded connection 22. The opening 23 of the screw cap 24 is preferably configured, particularly shaped and/or sized, so that a person can drink from it. The drinking vessel 20, including a cup 21 and a screw cap 24 with an opening 23, is preferably a drinking vessel that is commonly used in the healthcare field, such as in hospitals or medical practices.

In the second and third stages, the lower cap 7 at the first hole 4 of the body 3 of the applicator 1 is removed (FIG. 4b), and the applicator 1 is attached to the hole 23 of the screw cap 24 (FIG. 4c). At the fourth stage (FIG. 4d), the upper cap 8 is removed from the second hole 5 of the body 3 of the applicator 1.

In a fifth step (FIG. 4e), the drinking vessel 20, together with the applicator 1 attached thereto, is tilted to allow liquid (indicated by a dotted arrow) to flow out of the cup 21 through the first opening 4 of the body 3 and subsequently at least partially through the holder 6, in which the swallowable object 2 is housed. Due to the fact that liquid flows through the holder 6 and/or under the influence of gravity, the swallowable object 2 moves to the second opening 5 of the housing 6, where it is “washed out” by the liquid flowing from the second hole 5, and can be swallowed by the patient drinking from the second hole 5.

In FIG. 5 a)-d) show exemplary assembly steps of the applicator 1 in a cross-sectional view.

In a first step (FIG. 5a), a holder 6 is provided. In a second step (FIG. 5b), a swallowable object 2 is inserted and/or placed into the holder 6 such that the swallowable object 2 is preferably held by the lower structure 9 of the holder 6 and /or preferably abuts the wall-like structure 10 of the holder 6. The swallowable object 2 is preferably a dosage form, for example a capsule, pill or tablet, to which a first end of a thread or cord (not shown) is attached.

Before inserting the object 2 into the holder 6, the thread is preferably inserted into the holder 6 and/or laid on or along it. For example, the thread may be laid in an "8" shape through and around the holder 6, repeating the following sequence: i) winding the thread around the first half of the wall-like structure 10, ii) guiding the thread through two opposing grooves 12 provided in the wall-like structure 10, through the inside of the holder 6, iii) winding the thread around the second half of the wall-like structure 10 and iv) guiding the thread through two opposite grooves 12 through the inside of the holder 6.

Preferably, the second end of the thread or cord, which is not attached to the object 2, can be secured to a locking element 11 provided on the outer surface of the wall-like structure 10. Alternatively or in addition, a locking element 11 or any other element with a similar function of fixing the thread can be provided in another place on the holder 6 and/or housing 3, for example, in the lower structure 9 and/or on the inner surface of the wall-like structure 10.

In a third step (see arrow in FIG. 5b), the holder 6, together with the object 2 contained therein, is inserted into the housing 3. Preferably, a flange 13 and an inclined projection 14 are provided at the bottom of the holder 6. Moreover, preferably adjacent to the first opening 4 of the housing 3 there is an annular rib 15 which fits between the flange 13 and the projection 14. Preferably, when the holder 6 is inserted into the body 3 from below, the inclined projection 14 can pass through the rib 5 in the direction indicated by the arrow, but acts as a notch in the opposite direction, so so that the holder 6 is fixed on the inner wall of the housing 6 by means of a geometric closure of the rib 15 between the flange 13 and the projection 14. This is shown in FIG. 5s.

In the fourth and fifth stages (see FIG. 5d), the upper cap 8 and the lower cap 7, respectively, are attached to the housing 3 to seal the second opening 5 and the first opening 4 of the housing 3, respectively.

In FIG. 6a)-c) show different perspective views of an exemplary holder 6, while FIG. 6a shows a cross-section of the holder 6. In general, with respect to the lower structure 9, the wall-like structure 10, the fixing members 11, the grooves 12, the flange 13 and the projections 14, the above explanations can be applied accordingly.

As can be seen from FIG. 6b and 6c, in this example, two grooves 12 are provided on opposite sides of the wall-like structure 12. In general, it is possible to provide fewer or more two grooves 12, for example, four grooves spaced at 90° intervals around the wall-like structure 12.

As can be seen from Fig. 6a and 6c, the lower structure 9 of the holder 9 is a cross-shaped structure, which effectively prevents an object 2 housed inside the holder 6 from passing through the lower structure 9 and entering the liquid reservoir. In general, any other type of grille can be used which, on the one hand, is permeable to liquids and, on the other hand, prevents the placed object 2 from passing the lower structure 9 towards the liquid reservoir. The lower structure 9 preferably has openings that are smaller than the cross-section of the object 2 placed inside the holder 6, in particular the dosage form.

Additional examples of the applicator 1 are now described with reference to the figures, which show only certain aspects of the applicator 1, while other details are omitted for the sake of simplicity of explanation. However, it should be understood that the (not shown) details of the following examples may be at least partially constructed in a manner similar to that of the applicator 1 examples described above.

In FIG. 7 is a perspective view of another exemplary applicator. The housing 3 has a substantially tubular or sleeve-like basic shape and is fitted onto the flange structure 13 of the holder 6 for frictional and/or positive engagement with the holder 6.

As in the above examples, two grooves 12 are provided in the annular wall structure 10 of the holder 6. In this example, the grooves 12 extend from the upper end of the wall structure 10 to the lower end of the wall structure 10, where the flange structure 13 is provided.

Moreover, in this example, the ingestible object 2 housed within the holder 6 is held and/or rested on a shelf, track or bridge 16 formed by a plurality of pieces of thread 17 that is attached to the ingestible object 2 and repeatedly passed through the grooves 12 through the inside of the holder 3 and around the outer surface of the holder 6. In this example, as shown in the figure, the thread is laid in a shape resembling an "8". In this regard, the explanations given above with reference to FIG. 5b apply accordingly in this case as well.

In addition, preferably one end of the thread 17 is attached to the object 2, while the other end of the thread 17 is attached to the applicator 1, preferably by clamping the end of the thread 17 between the body 3 and the flange structure 13 of the holder 6 while sliding the body 3 onto the flange structure 13 of the holder 6 .

In FIG. 8 is a perspective view of another exemplary applicator 1. In general, the explanations given above with reference to FIG. 7 apply accordingly in this case. Unlike the example shown in FIG. 7, in which the slots 12 have a substantially fixed width, the width of the slots 12 in this example increases towards the upper end of the holder 6. Preferably, the slots 12 are trapezoidal in shape. In this case, a particularly reliable unwinding of the thread 17 from the holder 6 is ensured.

In FIG. 9 is a perspective view of another exemplary applicator 1. In general, the explanations given above with reference to FIG. 8 apply accordingly in this case. Unlike the example shown in FIG. 8, the height of the wall-like structure 10 of the holder 6 is reduced. Preferably, the height of the wall-like structure 10 is approximately 30 to 80%, preferably 50 to 60%, of the height of the body 3. In this case, unwinding of the thread 17 from the holder 6 is further simplified.

In FIG. 10 a) and b) show, respectively, a front view and a perspective view of another exemplary applicator. In general, the explanations given above with reference to FIG. 9 apply accordingly in this case. Unlike the example shown in FIG. 9, the height of the shoulder 18 adjacent to the flange 13 has been increased to provide an even more stable fixation of the housing 3 and the holder 6.

In FIG. 11 a) and b) show a front view and a perspective view of another exemplary applicator. In general, the explanations given above with reference to FIG. 10 are appropriately applicable in this case as well. Unlike the example shown in FIG. 10, the wall-like structure 10 has a substantially conical base shape with a total of four slots 12, which allows for particularly secure unwinding of the thread (not shown) from the holder 6.
