Abstract

The present invention relates to a device for home monitoring of haematological parameters of patients. In particular, the device may be configured for home monitoring of patients undergoing chemotherapy. A white blood cell counter is presented in combination with a physically separated user device. The user interface and the white blood cell counter are configured to exchange data with each other. The present invention allows the white blood cell counter to be produced at lower costs, since no display is integrated into it directly. The patients may use the user interface device anywhere in their home or even on the go, allowing the maximum in freedom to fill in patient-reported outcomes or health assessment questionnaires. Also taking temperature readings is facilitated. In the home, a white blood cell test can be performed if required. The user interface guides the patient through the correct process and may therefore be brought to the cell counter.

Claims

1. Device for home monitoring of haematological parameters of patients, the device comprising:

a white blood cell counter,

a user interface,

wherein the white blood cell counter is configured for receiving a blood sample probe and to determine a value of white blood cells in the received sample probe,

wherein the user interface is physically separated or physically separable from the white blood cell counter, and

wherein the user interface is configured to display information based on the value of white blood cells in the received blood sample probe as determined by the white blood cell counter.

2. Device according to claim 1, further comprising

a thermometer configured to determine a value of a body temperature of the patient, and

wherein the thermometer and the user interface are configured to provide the determined value of the body temperature to the user interface.

3. Device according to claim 2,

wherein the thermometer comprises an interface, in particular a Bluetooth interface, for wireless communication with the user interface.

4. Device according to claim 1,

wherein the white blood cell counter and the user interface are configured to provide the determined value of white blood cells in the received blood sample probe to the user interface.

5. Device according to claim 2,

wherein the user interface stores a white blood cell intervention level,

wherein the user interface stores a temperature intervention level,

wherein the user interface is configured for comparing the provided, determined value of the body temperature with the temperature intervention level, and

wherein the user interface is configured for comparing the determined value of white blood cells in the received blood sample probe with the white blood cell intervention level.

6. Device according to claim 5,

wherein the user interface is configured for generating a signal based on a result of the comparison, and

wherein the signal is chosen from the group comprising a visual alert for the patient, an optical alert for the patient, a sms to a clinician, an email to a clinician, an alert message to a server, and any combination thereof.

7. Device according to claim 1,

wherein the user interface comprises a display and an electronical storage medium, and

wherein a health assessment questionnaire for the patient is stored in the electronical storage medium for displaying the health assessment questionnaire to the patient by the display.

8. Device according to claim 1,

wherein the user interface is configured to transmit information to a remote server.

9. Device according to claim 1,

wherein the white blood cell counter is a display-less device.

10. Device according to claim 1,

wherein the portable white blood cell counter comprises a first mechanical docking connector for establishing a connection with the user interface, and

wherein the user interface comprises a second mechanical docking connector for establishing a connection with the white blood cell counter.

11. Device according to claim 10,

wherein the user interface and the white blood cell counter are configured, in a configuration where the user interface is docked to the white blood cell counter, to charge the user interface by the white blood cell counter, to transmit readings from the user interface to the white blood cell counter, and/or synchronize results from white blood cell counts.

12. Device according to claim 1,

wherein the device is configured to be used with multiple user interfaces.

13. Method of home monitoring of haematological parameters of patients, the method comprising the steps of:

determining a value of white blood cells of a blood sample probe of the patient by a white blood cell counter (S1), and

transmitting the determined value of white blood cells from the white blood cell counter to a physically separated or physically separable user interface (S2),

displaying on the user interface information based on the value of white blood cells in the received blood sample probe as determined by the white blood cell counter (S1).

14. Method according to claim 13, the method comprising the step of:

receiving a value of a body temperature of the patient by the user interface from a thermometer (S4).

15. Method according to claim 14,

wherein the user interface stores a white blood cell intervention level,

wherein the user interface stores a temperature intervention level,

comparing the provided, determined value of the body temperature with the temperature intervention level by the user interface, and

comparing the determined value of white blood cells in the received blood sample probe with the white blood cell intervention level by the user interface.

16. Method according to claim 15,

generating a signal based on a result of the comparison by the user interface, and wherein the signal is chosen from the group comprising a visual alert for the patient, an optical alert for the patient, an sms to a clinician, an email to a clinician, an alert message to a server, and any combination thereof.
