Abstract
An external medical device includes a first cartridge bay with a first cartridge port, a second cartridge bay with a second cartridge port, a fluid outlet in fluid communication with the first cartridge port, a fluid pump configured to deliver a therapeutic fluid from a fluid cartridge engaged with the first cartridge port through the fluid outlet in response to fluid outlet control signals, a fluid inlet in fluid communication with the second cartridge port, and a fluid control structure in fluid communication with the fluid inlet to control fluid flow through the fluid inlet.
Claims20
An external medical device comprising:
- a housing;
- a first cartridge bay with a first cartridge port, wherein the first cartridge bay is formed from a first recess within the housing, the first recess sized to contain a first cartridge engaged with the first cartridge port within an outer profile of the housing;
- a second cartridge bay with a second cartridge port, wherein the second cartridge bay is formed from a second recess within the housing, the second recess sized to contain a second cartridge engaged with the second cartridge port within the outer profile of the housing;
- a fluid outlet in fluid communication with the first cartridge port;
- a fluid pump configured to deliver a therapeutic fluid from a fluid cartridge engaged with the first cartridge port through the fluid outlet in response to fluid outlet control signals;
- a fluid inlet in fluid communication with the second cartridge port;
- and
- a fluid control structure in fluid communication with the fluid inlet to control fluid flow through the fluid inlet.
A method for delivering a therapeutic fluid to a joint capsule of a patient, the method comprising:
- storing an identification of a first cartridge in a memory of a control module;
- sending instructions based on the stored identification, from the control module to a fluid pump of an external medical device, to activate the fluid pump in order to deliver the therapeutic fluid from the first cartridge via a fluid outlet of the external medical device into the joint capsule via a first tubing segment;
- and
- sending instructions based on the stored identification, from the control module to a fluid control structure of the external medical device, to operate the fluid control structure in order to control flow from the joint capsule via a second tubing segment into a second cartridge via a fluid inlet of the external medical device,
- wherein the external medical device includes:
- a housing;
- a first cartridge bay with a first cartridge port, wherein the first cartridge bay is formed from a first recess within the housing, the first recess sized to contain the first cartridge engaged with the first cartridge port within an outer profile of the housing;
- a second cartridge bay with a second cartridge port, wherein the second cartridge bay is formed from a second recess within the housing, the second recess sized to contain the second cartridge engaged with the second cartridge port within the outer profile of the housing;
- the fluid outlet, which is in fluid communication with the first cartridge port;
- the fluid pump, which is configured to deliver the therapeutic fluid from the first fluid cartridge engaged with the first cartridge port through the fluid outlet in response to fluid outlet control signals;
- the fluid inlet, which is in fluid communication with the second cartridge port;
- and
- the fluid control structure, which is in fluid communication with the fluid inlet to control fluid flow through the fluid inlet.
