First Claim
1. A disposable tubeless fluid delivery system, comprising:
- a button unit configured to receive instructions given by a user through pressing button;
a key unit configured to output a selection instruction indicating at least one working mode, wherein the at least one working mode is selected from a group including a basal rate delivery mode, a programmable basal rate delivery mode, a delivery suspend mode, a system locking mode and a wireless control mode;
a fluid reservoir unit configured to store a fluid;
an indwelling unit configured to let through the fluid to a patient when it is implanted in a subcutaneous tissue of the patient, wherein the indwelling unit comprises an indwelling cannula configured to be implanted in the subcutaneous tissue of the patient;
a fluid driving unit configured to deliver the fluid stored in the fluid reservoir unit to the subcutaneous tissue of the patient via the indwelling unit, when it receives a delivery instruction; and
a control unit coupled to the button unit, the key unit, the fluid reservoir unit, the indwelling unit and the fluid driving unit, wherein the control unit is configured to, when it receives a button-pressing instruction, the selection instruction of the working mode, or a combination thereof, output the corresponding delivery instruction to the fluid driving unit, so as to control the fluid driving unit to deliver the fluid or suspend fluid delivery;
wherein the key unit comprises a plurality of keys (13) and a first socket (12), each of the plurality of keys (13) comprises a key shell (130), a built-in electric circuit located inside the key shell (130), and a first plug (131), where a first portion of the first plug (131) is embedded in the key shell (130) and a second portion of the first plug (131) protrudes out of the key shell (130), and the first socket (12) comprises a first groove (123) with a first slot (124) disposed on a bottom of the first groove (123), where a side wall of the first groove (123) surrounds the first slot (124), the second portion of the first plug (131) is configured to be inserted into the first slot (124) from an opening side of the first groove (123) and the key shell (130) is configured to contact with the side wall of the first groove (123), and the first socket (12) further comprises a second slot (120) disposed on a side of the first groove (123) opposite to the opening side and a first connector (121) set in the second slot (120), where the first connector (121) is configured to be electrically connected with the built-in electric circuit when the each of the plurality of keys (13) is inserted into the first socket (12).
