## Abstract

The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. The flow activator may be actuated in a deployment direction by a deployment actuator, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, an effector may enable fluid communication between the opening and the vacuum source and may do so in response to actuation of the flow activator.

## Claims

### Claim at position 1

1-7. (canceled)

### Claim 8

A material delivery/receiving device, including:
a flow activator arranged to cause delivery of a material to a subject and/or to cause release of blood or other material from the subject, the flow activator including one or more needles arranged to penetrate skin of a subject; and
a material source arranged to provide a drug or other material to the subject, the material source being penetrated by the one or more needles for delivery of material in the material source to the subject in response to actuation of the device,
wherein the one or more needles do not penetrate the material source prior to actuation of the device.

### Claim 9 (depends on 8)

The device of claim 8, wherein the material source includes a drug eluting hydrogel arranged to release a drug for delivery to skin openings formed by the one or more needles.

### Claim 10 (depends on 8)

The device of claim 8, wherein penetration of the material source by the one or more needles causes the one or more needles to be coated by the material in the material source.

### Claim 11 (depends on 8)

The device of claim 8, wherein the material source includes a dissolvable material.

### Claim 12 (depends on 8)

The device of claim 8, wherein the material source includes a reservoir including the material.

### Claim 13 (depends on 12)

The device of claim 12, wherein the one or more needles are hollow and the material is forced through the hollow needle(s) and into a subject surface penetrated by the needle(s).

### Claim 14 (depends on 8)

The device of claim 8, further comprising a positive pressure source arranged to force the material from the reservoir.

### Claim 15 (depends on 8)

The device of claim 8, further comprising a device actuator, wherein actuation of the device actuator causes the one or more needles to move downwardly toward the skin of the subject, penetrate the material source, and penetrate the material source to deliver material in the material source to the subject.

### Claim 16 (depends on 14)

The device of claim 14, further comprising an effector, wherein actuation of the device actuator causes the effector to deploy the one or more needles to move relative to the material source toward the skin or other surface of the subject.

### Claim 17 (depends on 16)

The device of claim 16, wherein the effector comprises a snap dome actuator.

### Claim 18 (depends on 8)

The device of claim 8, wherein actuation of the device causes the one or more needles to penetrate the material source prior to penetrating the skin or other surface of the subject.
