## Abstract

A minimal action, invasive blood constituent device can streamline the process for the self-monitoring of blood-related tests by holding and facilitating the use of some or all of the tools for obtaining and testing a blood sample. The device can include a slider, that when pumped, causes the device to spring-load a lancet and eject a testing strip. The device can include a trigger that, when pressed, activates the lancet by unloading the spring. A strip-lancet apparatus can combine the roles of two disposable products—a testing strip and a lancing needle—into an apparatus that can be configured for piercing the testing site as well as receiving the blood sample. A testing strip apparatus can facilitate the use and/or disposal of testing strips. A lancet apparatus can facilitate the use and/or disposal of lancets.

## Claims

### Claim 1

An invasive blood constituent device comprising:
a trigger;
a testing strip;
a lancet; and
a slider,
wherein a predefined movement of the slider causes the device to load the lancet and/or present the testing strip,
wherein activation of the trigger after loading the lancet causes the device to activate the lancet, wherein activation of the lancet causes the lancet to prick a measurement site of a user.

### Claim 2 (depends on 1)

The device of claim 1, wherein the predefined movement comprises sliding the slider in a first direction and/or sliding the slider in a second direction.

### Claim 3 (depends on 2)

The device of claim 2, wherein said sliding the slider in the first direction causes the device to load the lancet, wherein said sliding the slider in the second direction causes the device to present the testing strip.

### Claim 4 (depends on 1)

The device of claim 1, further comprising a lancing spring, wherein loading the lancet comprises compressing the lancing spring, wherein activation of the lancet comprises decompressing the lancing spring.

### Claim 5 (depends on 1)

The device of claim 1, further comprising:
a testing strip cartridge comprising a plurality of stacked testing strips,
wherein the plurality of stacked testing strips comprises the testing strip; and
a strip guiding rod,
wherein the predefined movement of the slider causes the strip guiding rod to move the testing strip from the plurality of stacked testing strips and present the testing strip.

### Claim 6 (depends on 1)

The device of claim 1, further comprising:
a testing strip disposal bin configured to store testing strips,
wherein the predefined movement of the slider causes the device to add a used testing strip to the testing strip disposal bin.

### Claim 7 (depends on 1)

The device of claim 1, further comprising:
a lancet cartridge comprising a plurality of lancets, wherein the plurality of lancets comprises the lancet,
wherein the predefined movement of the slider causes the device to select the lancet from the lancet cartridge and load the lancet.

### Claim 8 (depends on 1)

The device of claim 1, further comprising:
a lancet disposal bin configured to store lancets,
wherein the predefined movement of the slider causes the device to add a used lancet to the lancet disposal bin.

### Claim 9 (depends on 6)

The device of claim 6, wherein the testing strip disposal bin is the same container as a lancet disposal bin.

### Claim 10 (depends on 1)

The device of claim 1, further comprising a glucometer configured to obtain data from the blood sample on the testing strip.

### Claim 11

A method of using an invasive blood constituent device comprising:
sliding a slider of an invasive blood constituent device according to a predefined movement, said sliding the slider in the predefined movement causes the device to load the lancet and/or present the testing strip; and
after loading the lancet, activating a trigger of the invasive blood constituent device, wherein activation of the trigger after loading the lancet causes the device to activate the lancet, wherein activation of the lancet causes the lancet to prick a measurement site of a user.

### Claim 12 (depends on 12)

The method of claim 12, wherein the predefined movement comprises sliding the slider in a first direction or sliding the slider in a second direction.

### Claim 13 (depends on 11)

The method of claim 11, wherein the invasive blood constituent device comprising one or more of the features of the device of any of the previous claims.

### Claim 14

A strip-lancet apparatus comprising:
a first layer comprising a testing strip for accepting a blood sample; and
a second layer comprising a lancing needle for pricking skin at a measurement site.

### Claim 15 (depends on 14)

The strip-lancet apparatus of claim 14, wherein the first layer is configured to move relative to the second layer.

### Claim 16 (depends on 14)

The strip-lancet apparatus of claim 14, wherein in a first configuration the lancing needle is exposed to a user, and wherein in a second configuration the lancing needle is isolated from the user.

### Claim 17 (depends on 14)

The strip-lancet apparatus of claim 14, wherein in a first configuration the first layer is offset from the second layer, and wherein in a second configuration the first layer is aligned with the second layer.

### Claim 18 (depends on 16)

The strip-lancet apparatus of claim 16, wherein to transition from the first configuration to the second configuration, the first layer is shifted relative to the second layer.

### Claim 19 (depends on 16)

The strip-lancet apparatus of claim 16, wherein the strip-lancet apparatus transitions from the second configuration to the first configuration responsive to force applied on the first layer by a launching mechanism.

### Claim 20 (depends on 16)

The strip-lancet apparatus of claim 16, wherein the strip-lancet apparatus transitions from the first configuration to the second configuration responsive to force applied on the first layer by a recoil mechanism.
