Blood phototherapy system integrated with an extracorporeal circulation treatment apparatus

Abstract

This invention discloses a blood phototherapy system integrated into an extracorporeal circulation therapy device, comprising a device body, an extracorporeal blood circulation path disposed within the device body and through which blood flows, an irradiation area disposed within the path, a phototherapy module disposed within the irradiation area, and a controller electrically connected to the phototherapy module. The controller controls the start, stop, or output of the phototherapy module based on blood flow, pressure, alarm, positioning, or other device operating states, allowing the blood to receive light under predetermined conditions. The irradiation area can be located within the device body or within a replaceable blood circulation assembly, thus balancing device integration, sterile isolation, and safety interlocking.

7. The blood phototherapy system as claimed in claim 1, wherein the light provided by the phototherapy module to the irradiation area includes at least one or a combination of unilateral irradiation, bilateral contrast irradiation, circumferential irradiation, multi-point incident irradiation, and reflective gain irradiation.

8. The blood phototherapy system as claimed in claim 1, wherein the operating status of the at least one device includes blood flow rate, pump speed, circuit pressure, bubble status, blood leakage status, temperature status, door status, cartridge positioning status, consumable identification status, oxygenator status, dialyzer status, device alarm status, or a combination thereof.

9. The blood phototherapy system as claimed in claim 1, wherein when the controller determines that the operating state of the at least one device does not meet predetermined safety conditions, it automatically stops or limits the output of the phototherapy module.

10. The blood phototherapy system as claimed in claim 1, wherein the controller records at least one phototherapy parameter and at least one extracorporeal circulation parameter to form operational traceability data.

11. A disposable irradiation blood circulation cartridge for use in extracorporeal circulation therapy devices, comprising: a cartridge body; a light-transmitting channel formed in the cartridge body for extracorporeal circulation blood to flow through; at least one positioning member for positioning the disposable irradiation blood circulation cartridge in a predetermined relative position with a phototherapy module within the device body when the disposable irradiation blood circulation cartridge is assembled to a device body; and at least one identification member for the device body to determine whether the disposable irradiation blood circulation cartridge is a compatible consumable.

12. The disposable irradiation blood circulation box as described in claim 11, wherein the light-transmitting channel is tubular, flat slit-shaped, serpentine, circumferential, or multi-faceted light-receiving cavity.

13. The disposable irradiation blood circuit cartridge as claimed in claim 11, wherein the cartridge body further includes a locking structure for securing the disposable irradiation blood circuit cartridge to the blood circuit mounting area of ​​the device body during assembly.

14. The disposable irradiation blood transfusion cartridge as claimed in claim 11, wherein the identification component is a mechanical key, magnetic mark, optical mark, barcode, QR code, RFID tag or a combination thereof.

15. An extracorporeal circulation therapy device, comprising: a device body; a controller; a blood circuit mounting area adapted to mount a replaceable blood circuit component; and a phototherapy module disposed on the device body and facing the blood circuit mounting area; wherein when the replaceable blood circuit component is mounted in the blood circuit mounting area, a portion of a light-transmitting channel in the replaceable blood circuit component forms an irradiation area, and the controller receives at least one device operation status signal and controls the phototherapy module to provide light to the blood flowing through the irradiation area according to a preset control rule.

16. The extracorporeal circulation therapy device as described in claim 15, wherein the controller only allows the phototherapy module to start after the replaceable blood circuit assembly has been located and identified as a compatible consumable.

17. The extracorporeal circulation therapy device as claimed in claim 15, wherein the phototherapy module and the replaceable blood circuit assembly have a non-contact optical coupling interface and are separated from disposable consumables by an isolation window.
