When the infusion bottle is used, when the infusion bottle in one of the infusion bottle containing box assemblies 22 finishes infusion, the infusion bottle can be lifted and pulled out, and then the infusion bottle in the other infusion bottle containing box assembly 22 is descended and is inserted into the needle 31 which is opposite to the infusion bottle. The inner pipelines of the needle head 31, the needle head seat 32 and the flow joint 33 are communicated, so that the continuous transfusion work can be realized, and the transfusion bottle can be switched.
In some embodiments, in order to achieve better guiding, as shown in fig. 9 and 10, the back surface of the iv bag 221 is provided with a guide rib 223 in the vertical direction. The front surface of the fixing plate 233 is provided with a guide groove 232 shown in fig. 14 in the vertical direction; the guide rib 223 and the guide groove 232 are complementary in shape and engaged with each other. Thus, the guiding groove 232 and the guiding protrusion 223 are matched with each other during the lifting process of the iv bottle assembly 22, so that the iv bottle assembly 22 can move only in the vertical direction.
The apparatus of the present application also has a matching control system, which as shown in fig. 4 includes a controller assembly 4, the controller assembly 4 including a controller 41. The transmission motors 211 are numbered as #1 transmission motor and #2 transmission motor, the infusion bottles in the corresponding infusion bottle containing box assemblies 22 are numbered as #1 infusion bottle and #2 infusion bottle, and the #1 transmission motor and the #2 transmission motor are respectively electrically connected with the controller 41, so that the controller 41 can control the forward rotation and the reverse rotation of the corresponding transmission motors 211 to further realize the lifting movement of the corresponding infusion transmission mechanisms 21 to the infusion bottle containing box assemblies 22.
The controller 41 further includes a button portion 42; the button portions 42 correspond to the actuator motor 211 and are also numbered as a #1 button portion and a #2 button portion. The button 42 is electrically connected to the controller 41 as shown in fig. 15, and the button # 1 and the button # 2 are provided with an up button and a down button, respectively. When the infusion bottle storage box assembly is used, corresponding signals can be sent to the controller 41 by pressing the ascending or descending buttons of the different button parts 42, and the controller 41 can control the corresponding transmission motor 211 to rotate forwards or backwards based on the received signals, so that the corresponding infusion bottle storage box assembly 22 can ascend and descend. For example, when the infusion is started, the descending button of the #1 button part is pressed to descend the corresponding infusion bottle accommodating box assembly 22, so that the infusion operation of the #1 infusion bottle is performed, and when the #1 infusion bottle finishes the infusion, the ascending button of the #1 button part is pressed to stop the infusion operation of the #1 infusion bottle; then the descending button of the button part # 2 is pressed, namely the infusion bottle # 2 is switched to carry out infusion work, thus realizing the automatic control of the whole infusion process and avoiding the trouble of manually replacing the infusion bottle.
Meanwhile, a flow sensor is arranged in the flow connector 33 and is electrically connected with the controller 41; flow connector 33 sends a flow signal to controller 41 based on the flow; the flow joint 33 controller 41 can control the transmission motor 211 to start and stop based on the received flow signal. Thus, after the #1 infusion bottle is inserted into the corresponding needle 31, the flow connector 33 can sense the flow signal, and further the corresponding # 1 transmission motor stops rotating, so that the corresponding infusion bottle containing box assembly 22 stops descending continuously, and infusion work of the #1 infusion bottle is started; when the flow rate decreases to a certain value, the flow connector 33 immediately judges that the infusion of the #1 infusion bottle is completed at this time, and feeds back a signal to the controller 41, and the controller 41 immediately responds to the signal, and adopts control to raise the corresponding infusion bottle accommodating box assembly 22 so as to stop continuing the infusion of the #1 infusion bottle, and switches to the #2 infusion bottle to continue the infusion.
As shown in fig. 16, the apparatus of the present application also has a matching method of use, including:
step S100: the infusion bottle is fixed in the infusion bottle containing box component 22 in an inverted mode, one end of the infusion tube is inserted into the flow connector 33, and the other end of the infusion tube is inserted into the body of the patient, so that the infusion preparation work is completed.
Step S200: the designated driving motor 211 is started to rotate forward, so that the corresponding infusion bottle containing box assembly 22 descends through the lifting movement until the flow connector 33 detects a flow signal. For example, if the designated driving motor 211 is the #1 driving motor, the corresponding infusion bottle accommodating box assembly 22 is controlled to descend, so that the #1 infusion bottle is inserted into the corresponding needle 31, and then the infusion operation of the #1 infusion bottle is started.
Step S300: it is determined whether the flow rate connector 33 detects a flow rate signal, and if not, the process proceeds to step S400. Namely, the infusion work of the #1 infusion bottle is continuously carried out, and the next step is carried out after the infusion of the #1 infusion bottle is finished.
Step S400: the driving motor 211 in step S200 is started to rotate reversely, so that the corresponding iv bottle assembly 22 is lifted by the lifting movement until the flow connector 33 does not detect a flow signal. For example, after the infusion with the #1 infusion bottle is completed, the infusion bottle housing case 22 attached to the #1 infusion bottle is controlled to be lifted up, the #1 infusion bottle and the corresponding needle 31 are pulled out, and the infusion operation with respect to the #1 infusion bottle is completed.
Step S500: the switching starts another driving motor 211 and returns to step S200. For example, after the infusion operation of the #1 infusion bottle is finished, the #1 transmission motor is immediately stopped, and then the #2 transmission motor is switched to start the infusion operation of the #2 infusion bottle.
The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
