The tube is identified. The advantage of providing the protrusion 14 on the surface of the infusion tube is that the manufacturing process is simple, and the protrusion can be formed in one time with the infusion tube. However, if the protrusion is to be processed on the formed infusion tube, the infringement is extremely difficult.

As shown in FIG. 5 and FIG. 6, the infusion tube identification device 24 includes a detecting unit 30, an actuator 32, a reminding unit 33, and the like. The detecting unit 30 is configured to detect an identification signal returned from the infusion tube, and output an execution signal according to the detection result.

Embodiment 2:

The invention also protects a control method of the infusion pump, as shown in FIG. 7, the method mainly comprises the following steps:

Step S701: The infusion tube is installed at the infusion tube installation position 21 of the infusion pump, and the infusion pump is powered on.

Step S702: Before the infusion pump is infused, the infusion tube is identified by the infusion tube identification device. For example, the detecting unit 30 identifies the identification portion 13 on the infusion tube by detecting an identification signal returned from the infusion tube. The detection method differs depending on the identification unit 13 of a different type. When the identification portion 13 is a coating layer or an identification pattern on the infusion tube, the coating layer or the identification pattern is detected by image sensing; when the identification portion 13 is the protrusion portion 14 on the surface of the infusion tube, the contact type induction and the reflection type are used. The protrusion 14 is detected by means of light sensing or reflective light sensing, and when the detecting unit 30 detects whether the corresponding position of the surface of the infusion tube has the protrusion 14.

When the identification portion 13 is a coating or identification pattern on the infusion tube, in an identification authentication method, if the detecting unit 30 detects that there is a coating or an identification pattern on the infusion tube, indicating that the identification is authenticated, the process proceeds to step S705; otherwise, If the authentication mode is not passed, the process proceeds to step S704. In another more accurate identification and authentication method, after detecting the identification pattern, the detecting unit 30 compares whether the detected identification pattern is consistent with the preset identification pattern. The authentication is confirmed, and the process proceeds to step 705; otherwise, the authentication is not passed, and the process proceeds to step S704. When the identification portion 13 is the protrusion portion 14 on the surface of the infusion tube, if the detection unit 30 detects that the corresponding position of the surface of the infusion tube has the protrusion portion 14, indicating that the authentication is passed, the process proceeds to step S705, and otherwise the authentication is not passed, and the process proceeds to step S704.

Step S704: When the infusion tube fails to pass the identification certification, the infusion pump sends an execution signal to stop the infusion, so that the actuator 32 stops driving the infusion tube for automatic infusion, and can also output the detection result to the reminding unit 33, for example, by using a screen display or sounding. The method prompts the user to replace the infusion tube, and after the replacement, returns to step S702 to re-detect.

Step S705: By identifying the authentication, an execution signal for initiating the infusion is sent to the infusion pump, and the actuator 32 of the infusion pump drives the infusion tube to perform automatic infusion, and can also output the detection result to the reminding unit 33 to remind the user to perform the corresponding operation.

The invention recognizes the infusion tube by detecting the specific identification portion 13 on the infusion tube, thereby effectively identifying the source of the infusion tube, avoiding the safety hazard caused by the counterfeit infusion tube to the patient, and significantly improving the safety performance of the infusion tube.

The above is a further detailed description of the present invention in connection with the specific embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
