Abstract

Disclosed is a disposable tubeless fluid delivery system, comprising a button unit for receiving instructions given by a user through pressing button, a key unit for outputting a selection instruction indicating at least one working mode a fluid reservoir unit for storing a fluid, an indwelling unit for letting through the fluid to a patient, wherein the indwelling unit comprises an indwelling cannula, and a fluid driving unit for delivering the fluid stored in the fluid reservoir unit to the subcutaneous tissue of the patient by the indwelling unit, and a control unit for outputting the delivery instruction to the fluid driving unit and controlling the fluid driving unit to deliver the fluid or suspend fluid delivery. In the present disclosure, a pump base and a wireless control device are integrated to achieve a purpose of small volume, low cost and convenient wearing.

Claims

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 consisting of a basal rate delivery mode, a programmable basal rate delivery mode, an 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 key and a socket.

2. The disposable tubeless fluid delivery system according to claim 1, wherein the button unit comprises physical buttons, touch buttons, or a combination thereof.

3. The disposable tubeless fluid delivery system according to claim 2, wherein the physical buttons comprise a first physical button configured to set the fluid dose, and a second physical button configured to input a confirmation instruction;

one of the two physical buttons is provided with raised dots to be distinguished with the other physical button.

5. The disposable tubeless fluid delivery system according to claim 1, wherein the key comprises a key shell, a built-in electric circuit located inside the key shell, and a plug embedded in the key shell, wherein an O-shaped sealing ring is circumferentially set on the key shell.

6. The disposable tubeless fluid delivery system according to claim 5, wherein the built-in electric circuit is an analog circuit comprising electric resistances, electric capacities or a combination thereof, or a digital integrated circuit including Flash, EEROM, or one-time DATA BURNING type memory device, or a digital integrated circuit with identity recognition function, or a digital integrated circuit with an authentication function, an encryption function or a combination thereof, or a digital-analog hybrid integrated circuit.

7. The disposable tubeless fluid delivery system according to claim 5, wherein the socket includes a slot and a connector set in the slot, and the connector is used to be electrically connected with the built-in electric circuit when the key is inserted into the socket, wherein an O-shaped sealing ring is set on the surface on which the connector is attached with the socket, wherein the plug is inserted into the connector and thus electrically connected with the connector when the key is inserted into the socket, wherein the O-shaped sealing ring on the key shell and the socket fit tightly to achieve waterproof seal.

8. The disposable tubeless fluid delivery system according to claim 1, wherein the socket is a sealed groove, and the key is a sensing key which comprises a key shell and a sensor circuit located in the key shell.

9. The disposable tubeless fluid delivery system according to claim 8, wherein the sensor circuit includes a magnetic sensor, an optical sensor, a near field communication (NFC) tag or a radio frequency identification (RFID) tag.

10. The disposable tubeless fluid delivery system according to claim 1, wherein the key further comprises a handle configured to combine and separate the key and the socket.

11. The disposable tubeless fluid delivery system according to claim 1, wherein a buzzer cavity is set in a shell of the disposable tubeless fluid delivery system, a buzzer is set in the buzzer cavity, wherein the buzzer is configured to produce a buzz to sound an alarm, a reminder, or a combination thereof, and the buzzer is also configured to transmit ultrasonic data.

12. The disposable tubeless fluid delivery system according to claim 11, wherein the buzzer is connected to the control unit via a wire or a contact.

13. The disposable tubeless fluid delivery system according to claim 1, wherein a groove is set in a shell of the disposable tubeless fluid delivery system and a vibration motor is disposed in the groove, where the vibration motor is connected to the control unit via a wire.

14. The disposable tubeless fluid delivery system according to claim 1, wherein the disposable tubeless fluid delivery system further comprises an indicator light, a transparent portion is correspondingly set on the shell of the disposable tubeless fluid delivery system, such that the indicator light indicates a system state by flashing through the transparent portion.

15. The disposable tubeless fluid delivery system according to claim 1, further comprising a glucose sensor configured to dynamically monitor glucose level and a glucose monitoring module configured to process effective glucose signals output by the glucose sensor, wherein the glucose sensor is integrated in the indwelling unit, the glucose monitoring module is integrated in the control unit connected to the indwelling unit.

16.
