The present invention relates particularly, but not exclusively, to a fluid transfer apparatus, a fluid transfer system, and methods of transferring fluid. The present invention also relates to use of a fluid transfer apparatus.
Known fluid transfer apparatuses are often used to transfer fluid from a fluid receptacle to a further fluid transfer apparatus or device. The fluid receptacle or container is typically opened, or punctured, prior to connection to the fluid transfer apparatus.
When applying fluid to an animal body part in an agricultural setting, and when applying fluids to a person in a medical setting, it can be cumbersome and time-consuming for the operator of a fluid transfer device to open the fluid receptacle and then to connect, or engage, the fluid receptacle with the fluid transfer device.
Furthermore, some known fluid transfer devices make use of an exposed spike located on the fluid transfer device, which allows the user to pierce the fluid receptacle by engaging the fluid receptacle with the spike. However, this can cause injury to the user, particularly when used in an outdoor setting or when the user attempts to connect a fluid receptacle to a fluid transfer device as quickly as possible.
Moreover, such known devices can be prone to cause leakage from the fluid receptacle, as the fluid receptacle is not secured to the fluid transfer apparatus prior to engaging the fluid receptacle with the spike (or other means of opening the fluid receptacle).
Therefore, it would be desirable to provide a fluid transfer apparatus that could be used to open the fluid receptacle in a reliable, safe and efficient manner.
The inventors have appreciated the shortcomings in known fluid transfer apparatuses.

With reference to
The present invention is particularly well suited for use with fluid receptacles 10 that must be kept sterile prior to use, as the user cannot re-use the fluid transfer apparatus 1 by removing a used, potentially non-sterile fluid receptacle 10, and replacing it with a new, fluid receptacle 10. As the fluid transfer apparatus 1 is typically stored prior to engagement with a fluid receptacle 10, it is therefore easier to mitigate the build up of debris, and other residue, on the fluid transfer apparatus 1 prior to use with the fluid receptacle 10. In contrast, known fluid transfer apparatus 1, particularly in an agricultural or medical setting, are thought to often be intentionally re-used by the end-user despite the increased likelihood of accumulating debris, or other contamination, on the fluid transfer apparatus 1. However, it will be appreciated that in other embodiments the fluid transfer apparatus 1 could be configured such that a used fluid receptacle 10 could be replaced.
Furthermore, the fluid transfer apparatus 1 is operable to automatically align the fluid receptacle 10 to the fluid transfer apparatus 1, and to lock the fluid receptacle 10 to the fluid transfer apparatus 1, in a safe, reliable and efficient manner.
In the embodiments illustrated and described here, the fluid receptacle receiving portion 8 stabilises the fluid container 10 in use, which will be described in more detail below.
In use, the fluid transfer apparatus 1 is configurable from a first isolation state 12 (
The fluid transfer apparatus 1 is configured such that a fluid flow path exists from the fluid inlet 2, to the fluid transfer device 6, to the fluid outlet 4, such that, in use and in the second coupled state 14, fluid can flow from the fluid receptacle 1 to the fluid outlet 4 via the fluid flow path.
The fluid transfer apparatus 1 is operable to lock the fluid transfer device 6 in the second coupled state 14. In the embodiments illustrated and described here, the fluid transfer apparatus 1 is irreversibly configurable in the second coupled state 14, and the fluid transfer device 6 cannot be unlocked from the second coupled state 14. That is, the fluid transfer apparatus 1 is configurable from the first isolation state 12 to the second coupled state 14 and prevented from returning to the first isolation state 12. Therefore, in the embodiments illustrated and described here, when the fluid transfer apparatus 1 is in the second coupled state 14, the fluid transfer device 1 is secure and cannot be moved back to the first isolation state 12. This makes the fluid transfer apparatus 1 safer and more reliable to use, particularly with fluid receptacles 10 containing fluids that must be kept sterile. However, it should be appreciated that in other embodiments, the fluid transfer apparatus 1 could be configurable between the first isolation state 12 and the second coupled state 14.
In the embodiments illustrated and described here, the fluid transfer apparatus 1 is operable to irreversibly move the fluid transfer device 6 between a first position 16 and second position 18 when the fluid transfer apparatus 1 is configured between the first isolation state 12 and the second coupled state 14, such that the fluid transfer device 6 is locked at the second position 18. It should be appreciated that in other embodiments, when the fluid transfer apparatus 1 is configured between the first isolation state 12 and the second coupled state 14, the fluid transfer device 6 may not be movable.
As best shown in
As best shown in
The fluid receptacle receiving portion 8 is configured to connect and irreversibly secure at least a portion of the fluid receptacle 10 thereto. In the embodiments illustrated and described here, the fluid receptacle receiving portion 8 is configured to lock at least a portion of the fluid receptacle 10 with the fluid receptacle receiving portion 8 and the fluid receptacle 10 cannot be removed from the fluid receptacle receiving portion 8 when located therein. That is, the fluid receptacle receiving portion 8 is configured to prevent removal of at least a part of the fluid receptacle 10 from the fluid receptacle receiving portion 8 when the at least a portion of the fluid receptacle 10 is locked with the fluid receptacle receiving portion 8. It is advantageous to secure the fluid receptacle 10 to the fluid transfer apparatus 1 in this manner, as the fluid receptacle 10 is more stable during use and is less likely to break free from the fluid transfer apparatus 1.
The fluid transfer apparatus 1 is configured to shield and protect at least a portion of the fluid transfer device 6 in the first isolation state, which helps to prevent the fluid transfer device 6 from being damaged.
In the embodiments illustrated and described here, in the second coupled state 14 the fluid transfer apparatus 1 is configured to allow fluid to flow from the fluid inlet 2 to the fluid outlet 4 and to substantially prevent fluid flow from the fluid outlet 4 to the fluid inlet 2. In this arrangement, the fluid transfer apparatus 1 is configured to allow substantially unidirectional fluid flow from the fluid inlet 2 to the fluid outlet 4. As best shown in
As illustrated in
In the embodiments illustrated and described here, and with reference to
The fluid transfer apparatus 1 comprises a housing 30 configured to accommodate at least a portion of the fluid transfer device 6.
The housing 30 is configured to permit movement of the fluid transfer device 6 between the first position 16 and second position 18 when the fluid transfer apparatus 1 is configured between the first isolation state 12 and the second coupled state 14 and to substantially prevent movement of the fluid transfer device 6 from the second position 18 to the first position 16.
