Abstract

A medical device, such as a Huber-type device, includes a structure that enhances operator safety by reducing the likelihood that a needle will accidentally injure an operator. In one embodiment, the device includes a collapsible structure that can move from a use position to a non-use position. The device includes first and second wing portions and a channel for covering the needle as it is extracted from the patient. The structure enables the operator to leverage applied pressure for a smooth removal of the needle into the device for safe disposal.

Claims

1. A medical device, comprising:

a central structural member;

a needle extending from the central structural member;

at least one wing member extending from the central structural member to receive a first force;

a first member coupled to the central structural member, the first member for capturing the needle as it is removed from the patient, the first member to receive a second force in a direction generally opposing the first force;

a base member for placement against a patient'"'"'s skin, the base member pivotably coupled to the first member; and

a second member pivotably coupled to the first member and the base member such that the device is movable from a use position in which the base member is adjacent the second member and a non-use position in which the first member is pivotably moved away from the base member and the needle is captured by the first member, wherein the first force and the second force cooperate to transition the medical device from the use position to the non-use position.

2. The device according to claim 1, wherein the first member includes a cavity for receiving the needle.

3. The device according to claim 2, wherein the first member includes a latching mechanism to retain the needle in the cavity.

4. The device according to claim 1, further including a first latch mechanism for securing the first member to the central structural member in the use position.

5. The device according to claim 4, wherein the first latch mechanism includes a tab to facilitate separation of the first member from the central structural member.

6. The device according to claim 1, further including a mechanism for providing unidirectional movement of the first member.

7. The device according to claim 1, wherein the first member includes a portion adapted for contacting an operator'"'"'s thumb.

8. The device according to claim 1, wherein the second member includes first and second pivotably coupled sub portions.

9. The device according to claim 8, wherein the first and second sub portions can be folded to stack under the first member in the use position.

10. The device according to claim 1, wherein the device is fabricated from one or more materials including PVC and polyethylene.

11. A Huber needle device, comprising:

a main structural portion;

a needle extending from the main structural portion;

first and second wing portions extending from the main structural portion, at least one of the first and second wing portions to receive a first force;

a first member coupled to the main structural portion, the first member including a cavity for capturing the needle, the first member to receive a second force in a direction generally opposing the first force;

a base member for contacting a patient'"'"'s skin in a use position of the device, the base member being pivotably coupled to the first member; and

a second member pivotably coupled to the base member and the first member, wherein the device has a first position in which the first and second members abut and the needle extends from the device and a second position in which the first and second members are pivotably moved away from the base member and the needle is captured by the cavity in the first member, wherein the first force and the second force cooperate to transition the Huber needle device from the first position to the second position.

12. The device according to claim 11, further including a first latch mechanism for securing the first member to the main structural portion.

13. The device according to claim 12, further including a second latch mechanism for retaining the needle in the channel.

14. The device according to claim 11, wherein the second member includes foldable first and second subportions.
