Description
- This application is a continuation of Ser. No. 15/548,250 filed Aug. 2, 2017, which is the U.S. national phase of International Application No. PCT/GB2016/050226 filed Feb. 2, 2016, which designated the U.S. and claims priority to GB Patent Application No. 1501697.5 filed Feb. 2, 2015, the entire contents of each of which are hereby incorporated by reference.
- An injection device particularly suited for, but not explicitly for, injecting a solid dose formulation into a human or animal body.
- Solid dose formulations can be introduced into a human or animal body at either low velocity through injection or high velocity fired from a rifle. High velocity dosing is not appropriate for introducing a solid dose formulation into a human body hence substantial efforts have been made to develop a solid dose formulation having the requisite shape and material properties to facilitate ease of injection into a human body. In some cases, solid dose formulations can be introduced into a human body by methods as simple as pushing the solid dose formulation through the skin without aid of a tool or device.
- However, in order to avoid causing undue damage to the human body it is desirable to introduce a solid dose formulation by applying only the force necessary for the solid dose formulation to penetrate the human body. Human skin has a relatively low strength hence it is easy to apply too great a force to the solid dose formulation using manual application methods alone.
- Use of a tool or device to introduce a solid dose formulation into a human body is known. Typically a tool, or a portion of such a tool, requires to be disposed of after a single use for hygiene and sanitation purposes. The tool, or portion thereof, should be disposed of in such a manner that it is destroyed by means of incineration or otherwise. This can be problematic as many medical tools or devices are constructed from materials with high temperature melting points. Medical tools and devices are also expensive to manufacture and therefore disposal is undesirable.
- The use of an actuator and cassette to inject a solid dose formulation into a human body is known. Such an actuator and cassette is described in PCT/EP2003/007859 which is hereby incorporated by reference.
- It has been recognised that patients, in some circumstances, do not use injection devices in the correct manner if left to follow instructions provided with the injection device. A demonstration on how to use an injection device has been shown to reduce errors made by patients in using injection devices. However, known injection devices typically require the patient to handle a cassette which contains a solid dose formulation. Any handling can compromise sterility of the cassette and the solid dose formulation leading to potential infection at an injection site.
- The present invention seeks to address the aforementioned problems.
- An aspect of the invention provides an injection device for injecting a solid dose formulation into a human or animal body, the injection device comprising an actuator having a cassette mounting portion; a cassette holder having a cassette storage portion; and a cassette selectively movable between the cassette storage portion and the cassette mounting portion, wherein, the cassette comprises a solid dose formulation and the actuator is receivable in the cassette holder to selectively move the cassette between the cassette storage portion and the cassette mounting portion.
- The injection device of the present invention eliminates the need for a user to handle the cassette thus maintaining sterility of the cassette. Preventing a user from handling the cassette also significantly reduces user error in use of the injection device. The cassette of the present invention can be disposed of separately to the actuator and/or cassette holder.
- The cassette storage portion may comprise a plurality of releasable retaining elements for selectively retaining the cassette. The cassette mounting portion may comprise a bayonet fitting for receiving the cassette. The bayonet fitting of the cassette mounting portion and the releasable fastening elements of the cassette storage portion may be co-operable such that rotation of the actuator in the cassette holder releases the releasable fastening elements to facilitate selective movement of the cassette between the cassette storage portion and the cassette mounting portion.
- The bayonet fitting of the cassette mounting portion may comprise a locking mechanism for locking the cassette to the bayonet fitting.
- The locking mechanism is advantageous in that the cassette is prevented from being inadvertently detached from the actuator before actuation.
- The cassette holder may comprise a cassette holder body and a cassette holder insert, the cassette holder insert being removable from the cassette holder body and defining the cassette storage portion. The cassette holder insert may be disposable.
- The actuator may be re-usable.
- A further aspect of the invention provides a method of injecting a solid dose formulation into a human or animal body, the method comprising: a) providing an injection device comprising an actuator, a cassette holder and a cassette, the cassette comprising a solid dose formulation b) selectively moving the cassette from the cassette holder to the actuator, c) operating the actuator to inject the solid dose formulation into a human or animal body and d) selectively moving the cassette from the actuator to the cassette holder for disposal.
- A further aspect of the invention provides a method of injecting a solid dose formulation into a human or animal body, the method comprising: a) providing an injection device comprising an actuator, a cassette holder and a cassette, the cassette comprising a solid dose formulation, b) aligning the actuator with the cassette holder, c) inserting the actuator into the cassette holder to engage the cassette, d) rotating the actuator relative to the cassette holder to lock the cassette to the actuator, e) withdrawing the actuator from the cassette holder, f) injecting the solid dose formulation into a human or animal body, g) aligning the actuator with the cassette holder, h) inserting the actuator into the cassette holder and i) rotating the actuator to lock the cassette to the cassette holder.
- Certain embodiments of the inventions are shown in the figures as described below:
-
FIG. 1 shows illustrative views of an injection device according to the present invention comprising an actuator assembly and a cassette holder. -
FIG. 2 shows a detailed view of the cassette holder ofFIG. 1 . -
FIG. 3 shows a detailed view of a cassette holder insert which is insertable into the cassette holder. -
FIG. 4 shows a graph of the number of errors made per patient when using a prior art injection device for the first time without receiving a demonstration prior to first use. -
FIG. 5 shows a graph comparing the number of errors made per patient when using the device for the first time without a demonstration prior to first use and after receiving a demonstration prior to second use. - The certain embodiments will now be described by way of reference to the figures.
- Referring to
FIG. 1 , anactuator assembly 10 andcassette holder 20 are provided for injecting a solid dose formulation into a human or animal body. - The
actuator assembly 10 comprises abody portion 12 and acassette mounting portion 14. Thebody portion 12 houses a mechanism for operating the actuator. Thecassette mounting portion 14 is configured to receive acassette 34 comprising a solid dose formulation into abayonette type fitting 16, or similar. - As shown in
FIG. 2 , thecassette holder 20 comprises acassette holder body 22 which is open at one end. Acassette holder insert 24 is insertable into the open end of thecassette holder body 22. Theinsert 24 comprises a cassette storage portion 26 which stores thecassette 34. The cassette storage portion 26 is defined by threecurved prongs 28 which are biased to urge against thecassette 34 to hold it in position. Thecassette holder body 22 andinsert 24 are made from plastic in one embodiment but thecassette holder 20 could also be made from metal. In one embodiment thecassette holder body 20 andinsert 24 are disposable. In other embodiments only thecassette holder insert 24 is disposable. - A plurality of cassette holders can be stored in a sterile packaging such as a vacuum formed packaging with individually removable seals. Alternatively, each individual cassette holder can have its own vacuum formed packaging, for example, and each packaged cassette holder can be stored in a non-sterile container
- In use, the
actuator assembly 10 is axially aligned with thecassette holder 20. Thecassette mounting portion 14 of theactuator assembly 10 is inserted into thecassette holder 20. The dose cassette mounting portion is co-operable with thecurved prongs 28 of theinsert 24 such that rotation of theactuator assembly 10 through sixty degrees in a pre-defined direction causes theactuator assembly 10 to act againstcurved prongs 28 and displace them relative to the cassette held therebetween. Thecassette 34 is then released by thecurved prongs 28 and retained by the bayonet fitting 16. Theactuator assembly 10 can only be rotated through a maximum angle of approximately sixty degrees. Rotation is limited by a stop (not shown) defined on either theactuator assembly 10 or within the cassette storage portion 26. - The
cassette 34 comprises a dosing end (not shown) and a mounting end 3). Themounting end 36 of thecassette 34 protrudes outwardly from the cassette holder insert 24. The mountingend 36 of thecassette 34 comprises a bayonet type fitting, or similar, which is co-operable with thebayonet type fitting 16 of thecassette mounting portion 14 of theactuator assembly 10. When theactuator assembly 10 is withdrawn from thecassette holder insert 24, thecassette 34 is retained by thebayonet fitting 16 of theactuator assembly 10. - The dosing end of the
cassette 34 comprises the solid dose formulation and is exposed when thecassette 34 is retained by theactuator assembly 10. - To inject the solid dose formulation into a human or animal body, the
cassette 34 is held against the skin at ninety degrees therefrom. Theactuator assembly 10 is pushed downwards until an audible click can be heard. The click signifies that the actuator mechanism has operated and injected the solid dose formulation from thecassette 34 through the skin and into the human or animal body. Once the solid dose formulation has been injected, theactuator assembly 10 is withdrawn directly from the injection site. - After the solid dose formulation has been injected into a human or animal body the
actuator assembly 10 is axially aligned with thecassette holder 24. TheCassette mounting portion 14 of theactuator assembly 10 is inserted into thecassette holder 20 after use. Rotation of theactuator assembly 10 through sixty degrees causes it to act against the threeprongs 28 of thecassette holder insert 24. Theactuator assembly 10 can only be rotated through a maximum angle of approximately sixty degrees. - Rotation is limited by a stop (not shown) defined on either the
actuator assembly 10 or within the cassette storage portion 26. The threeprongs 28 are resiliently biased in a position in which they hold thecassette 34 in place. The threeprongs 28 are displaced by application of a compressive or torsional force to enable the cassette to enter or exit a space defined between the prongs 28. Once thecassette 34 has entered the space between theprongs 28, theprongs 28 revert to their unstressed configuration and retain thecassette 34. The dosing end of the cassette is orientated away from the open end of thecassette holder body 22. Thecassette holder 20 and/orcassette holder insert 24 is then discarded in a safe manner. - Injection devices were tested to evaluate handling of cassettes by users. The following table sets out the sample data set used for the evaluation:
