Description

FIELD OF TECHNOLOGY

The present invention relates to a device for removing the protective caps of components for delivery from drug containers that are intended to be placed inside the drug delivery device, and more particularly, to a device for removing both rigid and flexible protective caps of needles from cartridges or syringes that are intended for placement inside an injection device, such as a pencil-type injector or an automatic injector.

State of the art

There are a number of drug delivery devices that have been developed and marketed for self-medication use. Many of these devices are provided with drug containers to which drug delivery components are attached or integrated, such as injection needles.

Some injectors have needle caps that can be detachably attached to the injection needles. The purpose of these protective caps for needles is to protect others from unintentional injuries from needle sticks, as well as to protect the needle from contamination.

A traditional type of needle cap is a cap or sheath made of an elastic and flexible material such as rubber, silicone or the like. Before drug delivery, said flexible cap is manually removed by pulling it from an injection needle.

A more modern version of the needle cap is also called the rigid needle cap or LCD (RNS). The LCD has an inner shell of an elastic and flexible material, such as rubber or silicone, which is surrounded by an outer coating of hard material, such as hard plastic. Before drug delivery, the LCD is removed manually by pulling from the injection needle the specified outer coating, as a result of which the inner flexible membrane is also contracted.

In the case of any of the aforementioned needle guard caps, there is a risk that the user will be injured on the exposed needle while removing the needle cap, whether it be a flexible or rigid needle cap. Some people may also experience discomfort when handling components so close to the needles. Therefore, some devices have been developed that can be attached to needle caps so as to reduce the risk of injury.

One such device is disclosed in document WO 2010/089589. In this case, an outer part is provided from the proximal or front end of the drug delivery device to facilitate the arrangement. When this device for drug delivery should be used, the specified part, contributing to the layout, is pulled from the device. A series of teeth is located inside the part facilitating the arrangement, each of which is provided with a plate extending outward and extending inward, so that when the part contributing to the arrangement is pulled together, these plates capture the rubber sheath of the needle that surrounds the needle. Thus, together with the part facilitating the arrangement, the rubber casing is also removed.

US 2010/0016793 discloses a similar device having a cap with gripping means in the form of backward protrusions that engage with a rubber sheath surrounding the injection needle when said cap is removed or pulled from the drug delivery device.

WO 2005/115508 discloses an injection device having a protective cap with which a rigid needle cap can be removed when a dose of a drug is to be delivered. The device of the specified protective cover, therefore, includes a gear ring of metal. When this cap with the indicated ring is pulled onto a rigid needle cap surrounding the injection needle of the drug delivery device, said ring is pressed into a rigid plastic material and a strong connection is established. When the specified protective cover is later removed, a hard cap for the needle follows.

However, even in the case of proper operation of the needle cap belonging to the corresponding type, not a single device was disclosed in which one could use needle caps belonging to several different types, such as, for example, flexible needle caps along with hard caps for needles. For some devices for the delivery of drugs, a development was carried out for working with various types of containers for drugs, provided either with rigid caps for needles or flexible caps for needles. Thus, each type of needle cap requires a particular solution that is not easily applicable to a different type of needle cap.

SUMMARY OF THE INVENTION

The aim of the present invention is to correct the disadvantages of devices of the prior art. More specifically, the achievement of such a modular structure, in which only one device for removing the caps of the components for delivery can be used, when the device for drug delivery can use containers for drugs provided with various caps of the components for delivery. Therefore, the solution of the present invention comprises means capable of gripping component caps for delivering more than one specific type, more specifically, needle caps. Therefore, the device according to the present invention is a device for removing caps of components for delivery, preferably caps for needles, which are designed to cover and protect components for the delivery of drugs that are rigidly attached or can be detached to containers with a drug designed to be placed inside the device for drug delivery, and in which the specified device contains a housing of the remover, adapted to accommodate component cap for inward delivery. The specified device is characterized in that the said case of the remover includes at least two sets of gripping elements extending inside it, and in that each set of gripping elements is configured to capture a cap of a delivery component of a specific type, so that it can Apply a variety of different component caps for delivery. Said drug delivery components, preferably injection needles, are rigidly or detachably attached to drug containers which are intended to be placed inside the drug delivery device, preferably an injection device such as a pencil-type injector or an automatic injector.

For example, a single drug delivery device may be designed to accommodate drug containers having different types of caps for delivery components, preferably needle caps. In this regard, it can be, for example, either a flexible needle cap or a hard needle cap, depending on the type of needle cap that is used for a particular drug delivery device. In such a case, said device may be provided with a first set of gripping elements capable of gripping a rigid cap for a needle, and a second set of gripping elements capable of gripping a flexible cap for a needle.

A preferred aspect related to the body of the remover is that at least two sets of gripping elements can be provided in which each set of gripping elements is configured and capable of using a particular type of cap for a needle, for example, or a hard cap for a needle, either a flexible cap for a needle.

In accordance with one aspect of the present invention, the remover body is an elongated, generally cylindrical body having proximal and distal ends and containing inner and outer peripheral surfaces. Although a cylindrical body of the remover is preferred, other shapes can also be used that can provide a closed cavity into which the needle cap fits.

In accordance with another aspect of the present invention, each set of gripping elements is arranged in a ring on the inner peripheral surface of the remover body, and in which each set of gripping elements is formed as a series of elongated components extending into the specified housing of the remover at a predetermined angle relative to the longitudinal axis of the device and towards the proximal end of the remover body.

In accordance with a further aspect of the present invention, said elongated components are resilient tongues made integrally with the body of the remover.

In accordance with yet another aspect of the present invention, said at least two sets of gripping elements are a first set of gripping elements located in or disposed of from the body of the remover and configured to grip a rigid needle cap; and a second set of gripping elements located in the specified housing of the remover or made as a whole with it and made with the ability to capture a flexible cap for the needle.

In accordance with a further aspect of the present invention, each of the rows of gripping elements of the second set includes a fastening portion that is slightly narrower than the rest of the gripping elements, so that bending is generally achieved in the radial direction, requiring less effort, and in which the proximal end each gripping element of the second set provides or is equipped with a pointed portion and shoulder portions on both sides of the specified pointed portion.

In accordance with another aspect of the present invention, said first set of gripping elements is located closest to the distal end of the remover housing, and said second set of gripping elements is closest to the proximal end of the remover housing or between the proximal and distal ends of the remover housing.

In accordance with a further aspect of the present invention, the device further comprises a lid and a hat configured to be rigidly connected to each other, preferably, said lid comprises a circumferentially extending slot for engaging with protrusions extending radially to the cylindrical portion of said cap.

In accordance with another aspect of the present invention, said cap and remover body are configured to be rigidly connected to each other; preferably, said cap comprises an annular groove for engaging with an annular edge or protrusion of the remover body.

In accordance with another aspect of the present invention, said lid is removably connected to a drug delivery device and is positioned such that it surrounds the remover body.

In accordance with a further aspect of the present invention, said lid is generally in the form of a tube with two openings, wherein the proximal opening is located at the proximal end of the cover, and the distal opening is located at the distal end of the cover, and in which each of the two openings has a plane perpendicular longitudinal axis of the device.

In accordance with another aspect of the present invention, said remover body is configured to extend through a proximal opening of the cap after rigidly attaching it to the cap so that the tubular portion of said cap fits inside said proximal opening.

The elongated components of the gripping elements may be flexible, or plastic, with respect to the needle cap that extends into the body of the remover. This may facilitate the placement of the specified cap for the needle in the inner space of the body of the remover.

In accordance with one aspect of the present invention, such a flexibility or ductility function can be achieved by designing elongated components and by selecting a material. With regard to the design of elongated components, they can be in the form of tongues having an appropriate width that gives them a certain rigidity, and a thickness that is less than the specified width, which provides the function of flexibility or bending. With respect to material selection, it may include a metal material or a plastic material having the ability to exhibit an elastic function for certain levels of force. Thus, the elongated components may shift to some extent when the needle cap is inserted into the body of the remover.

Further, the elongated components of the gripping elements can extend into the interior of the remover housing at a certain angle relative to the longitudinal axis of the device, and preferably in the proximal direction. In the case of this design, it is possible to insert the cap for the needle into the body of the remover, as a result of which the elongated components are plastically deformed and slide along the surface of the cap for the needle in one direction.

With regard to rigid needle caps having fairly rigid surface materials, it may be an advantage that the needle cap is gripped in the distal region of the outer surface of the rigid needle cap. Therefore, the first set of gripping elements may preferably be located in the distal region of the remover body, such that the gripping elements will extend the entire needle cap during insertion of the needle cap into the remover body. The length and position of the first set of gripping elements, in this aspect, can be such that they are to some extent pushed as a whole in the radial direction with the introduction of a rigid cap for the needle. Such a radial bending model can provide a strong grip action in the distal region of the rigid needle cap.

During insertion into the housing of the remover, the second set of gripping elements can also be pushed to a certain extent in the radial direction by means of a rigid cap for the needle, but in order not to exert undesirable forces on the outer surface of the rigid cap for the needle, the construction of the elongated components of the second set the gripping elements may provide for a reduced bending force so that the force of the second gripping elements is rather small during insertion of the rigid needle cap. The reduction in force can be achieved by removing material in a specific area of elongated components, such as, for example, in the area where they are attached or attached to the body of the remover.

As for the flexible cap for the needle, the second set of gripping elements, as mentioned above, can have a reduced bending force, so that the insertion of the flexible cap for the needle into the body of the remover is facilitated. The proximal ends of the elongated components of the second set of gripping elements then slide along the outer surface of the flexible needle cap. This is an advantage when the later specified flexible needle cap must be removed. Since the proximal ends of the elongated components are in contact with the surface of the needle cap and since the elongated components may have a certain angle of inclination relative to the longitudinal axis of the device, the proximal ends of the elongated components are pressed to the surface of the flexible cap for the needle and to the material as the remover body is pulled from the device for delivery because the cap is flexible and resilient.

In order to improve the gripping effect of the elongated components of the second set of gripping elements, the proximal ends may preferably have features that improve gripping. Such features may increase friction between elongated components to ensure proper grip contact. In accordance with one aspect of the present invention, a grip enhancing feature may include a pointed end portion capable of entering the material of a flexible needle cap. However, to limit the depth of penetration, a thrust surface or shoulder region adjacent to said pointed region may be provided. In this way, the elongated components will provide a firm grip, and at the same time, the risk of damage to the flexible needle cap is reduced.

In accordance with a further aspect of the present invention, the remover body may be configured to attach to a cap or similar part of the body of the drug delivery device, which may surround at least a needle cap and an injection needle within it, wherein said cap may be removable when the dose of the drug is to be delivered.

In this aspect, the cap may be provided with a hole or channel in the proximal direction. This channel, preferably, can be arranged to accommodate the body of the remover, so that the specified body of the remover, in turn, can accommodate a cap for the needle.

The body of the remover may, in this aspect, have a cap attached at its proximal end, so that the lid channel can be closed after the body of the remover has been placed inside the lid. In order to properly position the hat, the lid channel may comprise an annular slot in which the outer edge of the hat can be located. Further, in order to guarantee a good fit of the cap and a good connection between the cap / body of the remover and the protective cover, this cap may be equipped with locks that engage with the channel of the protective cover.

The solution according to the present invention, therefore, can provide the possibility of using rigid caps for needles along with flexible caps for needles by means of one device, due to the design of the body of the remover with at least two sets of gripping elements. Other types of needle caps may also be used by providing appropriate gripping elements.

This solution can facilitate the use of different containers containing drugs and different caps for needles for the same device for the delivery of drugs, thereby reducing the need for private solutions that are required in other cases. The first and second sets of gripping elements in accordance with the present invention do not interfere with or interfere with the use of any type of needle cap.

These and other aspects of the present invention, as well as related advantages, will become apparent from the following description of the invention and the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

In the present application, when the term "distal part / distal end" is used, we are talking about the part / end of the drug delivery device, or the parts / ends of its elements, which, when using the drug delivery device, are located farthest from the place on the patient’s body in which the drug is delivered. Accordingly, when the term “proximal part / proximal end” is used, it refers to the part / end of the drug delivery device, or the parts / ends of its elements, which, when using the drug delivery device, are located closest to the place on the body the patient in whom the drug is delivered.

The device for removing the protective caps of the components for delivery, preferably the device 10 for removing the protective caps for the needles, comprises, in the case of the illustrated embodiment, the body 12 of the remover located along the longitudinal axis 22 of the device, FIG. 1, and configured to receive a cap of a component for delivery, preferably a cap for a needle, in its interior. The device may also include a cover 14 that is removably attached to the proximal end of the drug delivery device, preferably an injection device, and / or more preferably an automatic injector. The device further comprises a cap 40, in which the cap 14 and the cap 40 are configured to be rigidly connected to each other, and in which the cap 40 and the removal housing 12 are configured to be rigidly connected to each other.

Cap

Said cover preferably has a generally two-hole tube shape, wherein the proximal opening 16 is located at the proximal end of the cover and the distal opening is located at the distal end of the cover, FIG. 2, and in which each of these two holes is parallel to a plane that is perpendicular to the longitudinal axis 22 of the device. Additionally, the proximal opening 16 preferably has a circumferential slot 46, FIG. 2.

Hat

Hat 40, FIG. 3, comprises a generally cylindrical part 38 and an end surface 42 located at the proximal end of said cylindrical part or made as a unit with it. The specified end surface 42 is preferably circular in shape and is perpendicular to the longitudinal axis 22 of the device. Additionally, the end surface extends radially slightly outward from the cylindrical portion 38. Said cylindrical portion 38 includes inner and outer peripheral surfaces. Preferably, the series of radially extending protrusions 44 is located on the outer surface of the cylindrical part or is made as a whole with it. More preferably, said projections 44 are arranged at a predetermined distance from each other. Additionally, the annular groove 36 is located on the inner peripheral surface of the cylindrical part 38.

Remover Housing

The housing 12 of the remover is an elongated, generally cylindrical housing containing the inner and outer peripheral surfaces. Said remover housing further includes at least two sets of gripping elements extending inside it, and in which each set of gripping elements is configured to capture a cap of a delivery component of a particular type. Preferably, each of said first and second sets of gripping elements is arranged in the form of a ring on the inner peripheral surface of the remover body. More specifically, each set of gripping elements is formed as a series of elongated components extending into the specified housing of the remover at a predetermined angle relative to the longitudinal axis 22 of the device and in the direction of the proximal end of the housing 12 of the remover. Preferably, said elongated components are resilient tongues made integrally with the body 12 of the remover. In this context, it is advisable that the body of the remover is made of a material that allows a shaping action, such as bending, melting or other plastic deformation, so that the elements 18 get the direction, as described above. In addition, the material of the elements is selected so that these elements receive a certain flexibility or elasticity, in General, in the radial direction of the body of the remover. Also, the stripper body 12 is preferably provided with an annular edge or protrusion 34, FIG. 3, on its outer peripheral surface and located at a predetermined distance from its proximal end.

Preferably, the remover housing comprises first 18 and second 24 sets of gripping elements, FIG. 1 located on the inner peripheral surface of the remover housing, more preferably, each of said first and second sets of gripping elements is arranged in the form of a ring on the inner peripheral surface of the remover housing.

Preferably, the first set 18 of gripping elements is located closest to the distal end of the remover housing, more preferably, at a predetermined distance from the distal end of the remover housing. The gripping elements 20 of the first set, in the illustrated embodiment, are formed as a series of elongated components extending into the body of the remover at an angle relative to the longitudinal axis 22 of the device and in the direction of the proximal end of the body 12 of the remover. Preferably, said elongated components may be tongues made integrally with the body 12 of the remover. The operation of the first set 18 of gripping elements will be described in more detail below.

The second set 24 of gripping elements, FIG. 1 is preferably located closest to the proximal end of the remover body or between the proximal and distal ends of the remover body. More preferably, in a more proximal position relative to the first set 18 of gripping elements. The gripping elements 26 of the second set, in the illustrated embodiment, are formed as a series of elongated components extending into the body of the remover 12 at an angle relative to the longitudinal axis 22 of the device and in the direction of the proximal end of the body 12 of the remover. Preferably, said second elongated gripping elements 26 may be tongues made integrally with the body 12 of the remover. Preferably, each of the gripping elements of the second set includes a fastening portion 28, which is slightly narrower than the rest of the gripping element, in order to achieve bending, generally in the radial direction, requiring less effort. In addition, the proximal end of each gripping element of the second set provides or is equipped with a pointed portion 30 and shoulder portions 32 on both sides of the specified pointed portion 30. The action of the second set 24 of gripping elements will be described in more detail below.

The edge or protrusion 34 of the body 12 of the remover is designed to interact with the annular groove 36 of the hat 40, Fig.3, for attaching or rigidly connecting the body 12 of the remover to the hat 40. After the specified body of the remover and the hat were attached or rigidly attached to each other , the housing 12 of the remover, configured to pass through the proximal opening 16 of the cover 14, is inserted through the proximal opening 16 of the cover 14, as a result of which the protrusions 44 of the cylindrical part 38 of the cap 40 interact with the circumferential the gap 46 of the cover 14, so that the cap 40 is locked or rigidly attached to the cover 14, thereby forming a device for removing caps of components for delivery, more preferably a device 10 for removing the protective caps for needles.

When arranging the device for removing the caps of the components for delivery with the device for delivering the drug, the specified device for removing the caps of the components for delivery is axially shifted towards the proximal end of the device for delivering the drug, FIG. 4, so that the cap of the delivery component enters the interior of the remover body 12, and in which at least one of the at least two sets of gripping elements interacts with or adjoins the cap of the delivery component.

Rigid needle cap

If the drug delivery device is equipped with an injection needle 50 that is covered by a rigid needle cap 52, FIG. 5, when the specified rigid cap 52 for the needle enters the inner part of the body 12 of the remover, the first set 18 of gripping elements will contact or interact with the outer surface of the hard cap for the needle and will to some extent be pushed outward in the radial direction, FIG. 5a, and then slide over the outer surface of the rigid needle cap until the distally directed abutment surface 54 of the cap 14 contacts the proximal directed end surface 56 of the body of the drug delivery device, FIG. 5b. In this position, the first set of 18 gripping elements is located in the distal region of the rigid cap for the needle, while the proximal ends of the first set of 18 gripping elements are pressed against the surface of the rigid cap for the needle, due to the bending force in the radial direction of the first set of gripping elements, FIG. 5b.

During insertion of the rigid cap 52 for the needle into the body of the exterminator 12, the second 24 gripping elements will be pushed as a whole in the radial direction, being in contact with the rigid cap for the needle, FIG. 5b, and the pointed portion 30 will slide close to the outer surface of the rigid cap for the needle, but the force from the second set of 24 gripping elements will be rather small due to the reduced area 28 of the material, which reduces the bending force of the second set of 24 gripping elements relative to the outer surface of the hard cap for needles.

When the cover 14 together with the body 12 of the remover has reached its final position, FIG. 5b, cap 14, and therefore the rigid needle cap 52, are ready to be removed in order to deliver a dose of the drug. When removing the cover 14 by pulling it in the proximal direction relative to the device for drug delivery, the housing 12 of the remover will also follow. The movement in the proximal direction of the body 12 of the remover causes a strong grip on the surface of the rigid cap for the needle proximally directed by the first set of 18 gripping elements. By this, the rigid cap 52 for the needle is removed when the protective cover 14 and the body 12 of the remover are removed. The injection needle is now free to use for penetration and dosing of a drug.

Flexible needle cap

If the drug delivery device is equipped with an injection needle 50 that is covered by a flexible needle cap 58, FIG. 6a, when said flexible needle cap is included in the inside of the remover body 12, the first set of gripping elements 18 will move outward from the outer surface of the flexible needle cap until the cap 14 is in this position relative to the body of the drug delivery device, as described above. During this movement, the second set 24 of gripping elements will be pushed as a whole in the radial direction, being in contact with the flexible cap for the needle, and will slide close to the outer surface of the cap for the needle, FIG. 6a.

When the cover 14 has reached its final position, FIG. 6b, cap 14, and therefore the flexible needle cap 58, are ready to be removed in order to deliver a dose of the drug. When removing the cover 14 by pulling it in the proximal direction relative to the device for drug delivery, the housing 12 of the remover will also follow. The movement in the proximal direction of the body 12 of the remover causes the tapered portion 30 of the second set of 24 gripping elements to be pressed into the material of the flexible cap for the needle, due to the inclined position of the second set of 24 gripping elements. However, the movement of the second set 24 of gripping elements with respect to the flexible cap for the needle stops when the shoulder portions 32 abut against the surface of the cap for the needle. The further movement of the body 12 of the remover and its set of 24 second gripping elements now makes the flexible cap for the needle move forward as a whole. By this, the flexible cap 58 for the needle is removed when the protective cover 14 and the body 12 of the remover are removed. The injection needle is now free to use for penetration and dosing of a drug.

It should be borne in mind that the embodiment described above and shown in the drawings should be considered only a non-limiting example of the present invention, and that it can be modified in many ways within the scope of the claims.
