Abstract

The invention relates to an arrangement for use with a medical device which arrangement comprises a shield for a tip of a needle member of a medical device. The arrangement comprises a filter for filtering gas to be transferred out from or into the medical device via the needle member when the arrangement is interconnected with the medical device. The filter is integrated with or constitutes at least a portion of the needle member tip shield.

Claims

1. An arrangement for use with a medical device, comprising:

a removably arranged shield for a tip of a needle member of a medical device;

a filter for filtering gas to be transferred out from or into the medical device via the needle member when the arrangement is interconnected with the medical device;

wherein the filter is integrated with or constitutes at least a portion of the shield and is configured to at least partially cover or surround the tip of the needle member of the medical device when the arrangement is interconnected with the medical device;

wherein the medical device comprises a container configured to be filled with gas that is passed through the filter while the medical device is not connected to a receptacle;

wherein the container has a variable volume and comprises a first portion made by a rigid material and a second portion made by a flexible material.

2. An arrangement according to claim 1, wherein shield is adapted to be arranged to at least partially cover or surround the tip of the needle member of the medical device when the arrangement is interconnected with the medical device.

3. An arrangement according claim 1 or 2, wherein the filter is adapted to be arranged to cover an opening of the needle member of the medical device when the arrangement is interconnected with the medical device.

4. An arrangement according to claim 1 or 2, wherein the filter is adapted to be arranged to enclose the tip of the needle member of the medical device when the arrangement is interconnected with the medical device.

5. An arrangement according to claim 4, wherein the filter is adapted to be partly penetrated by the tip of the needle member.

6. An arrangement according to claim 4, wherein the filter comprises a channel for receiving the tip of the needle member.

7. An arrangement according to claim 1 or 2, wherein the filter is adapted to be arranged in front of the tip of the needle member of the medical device when the arrangement is interconnected with the medical device.

8. An arrangement according to claim 1 or 2, wherein the shield is mainly or entirely constituted by the filter.

9. An arrangement according to claim 1 or 2, wherein the arrangement is adapted to be removably arranged on a medical device.

10. An arrangement according to claim 1 or 2, wherein the arrangement is adapted to be connected to a medical device so as to obtain an airtight connection between the medical device and the arrangement.

11. An arrangement according to claim 1 or 2, wherein the filter is a particulate air filter.

12. An arrangement according to claim 1 or 2, wherein the arrangement comprises a frame for accommodating the filter, which frame is connectable to a medical device.

13. A medical device provided with a needle member and an arrangement according to any of claims 1-2.

14. A medical device according to claim 13, wherein the arrangement is removably arranged on the medical device.

15. A medical device according to claim 13, wherein the arrangement is arranged on the medical device so as to obtain an airtight connection between the medical device and the arrangement.

16. A medical device according to claim 13, wherein the medical device is a device for providing cleaned gas to a receptacle.

17. A medical device according to claim 13, wherein the medical device is a device to be used in preparation of drugs.
