Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an intelligent automatic infusion replacement device. Background Technology

[0002] In clinical practice, postoperative, ICU, and critically ill patients require continuous infusion of multiple bags of fluids. Traditionally, this relies on nurses manually checking and changing bags, resulting in low levels of automation and information technology. Existing automated fluid exchange devices have the following core defects: 1. They only support a fixed infusion sequence and cannot adjust the infusion order or increase / decrease the number of bags midway through the process. The infusion sequence cannot be adapted to temporary clinical orders, resulting in extremely poor flexibility; 2. The continuous administration of different medications can easily lead to incompatibilities and cross-contamination. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an intelligent automatic fluid replacement device for infusion to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: An intelligent automatic fluid replacement device is provided, comprising: The suspension frame includes a suspension rod and a hanging frame.

While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0016] See Figure 1 As shown, the intelligent infusion automatic fluid replacement device of the present invention includes a suspension frame, a pluggable disposable sterile flow path interface 1, an intelligent main control unit 2, an automatic flushing unit 3, an automatic air venting unit 4, and several infusion passages.

[0017] The suspension frame includes a suspension rod 5 and a hanging bracket 6. The hanging bracket 6 is suspended in the air by the suspension rod 5. Several liquid bag hanging positions are arranged at intervals on the hanging bracket 6. Each liquid bag hanging position corresponds to a liquid bag 7. The liquid bag hanging positions are equipped with a weight sensor 8 and a status indicator light, which supports real-time addition / reduction / disabling of bags.

[0018] A pluggable, disposable, sterile infusion port 1 is located on the infusion pathway, corresponding to at least one infusion bag outlet (e.g., 1:1 or 1:2, etc.), and has a built-in mechanical check valve. The number of infusion pathways should preferably be 8-10, with a maximum of 20. The number of infusion pathway outlets should be set according to actual needs.

[0019] The intelligent main control unit 2 controls the opening and closing of each infusion channel and the infusion sequence based on external commands and feedback information from the weight sensor 8, and has a built-in audible and visual alarm.

[0020] The automatic flushing unit 3 is located in the infusion passage and connected to the intelligent main control unit 2. Specifically, it may include a pipeline with a flushing head, an on / off switch similar to a solenoid valve, a water pump, and a liquid storage tank.

[0021] Automatic exhaust unit 4 is connected to intelligent main control unit 2 and has a built-in anti-backflow one-way valve.

[0022] In a preferred embodiment, the suspension rod 5 is located at the center, and the hanger 6 is arranged in a ring around the suspension rod 5. The suspension rod 5 and the hanger 6 are connected by a transverse support rod 9. The suspension rod 5 is rotated circumferentially by external control (such as a stepper motor), thereby driving the hanger 6 to rotate together. The purpose of the rotation is to facilitate the physical connection of the liquid bag outlet to the pluggable disposable sterile flow path interface 1.

[0023] Considering the scalability of the number of liquid bag suspension positions, the number of hangers 6 on the suspension rod 5 can be increased or decreased. Specifically, hangers 6 with different inner diameters can be connected to the upper and lower positions of the suspension rod 5 by transverse support rods 9 of different lengths. The hangers 6 should be designed to prevent the liquid bags from colliding with each other.

[0024] The suspension rod 5 is preferably a telescopic structure, specifically a sleeve structure connected in order of inner diameter.

[0025] The intelligent main control unit 2 has a touch interface, which supports dynamic modification of the infusion order by touch dragging. Adjustments can be made in the middle without stopping the machine or disassembling the pipeline.

[0026] In a preferred embodiment, the device further includes a movable base 10, on which the suspension frame, infusion passage, intelligent main control unit 2, automatic flushing unit 3 and automatic venting unit 4 are all mounted for easy overall movement.

[0027] Specific implementation process: a. Initial assembly According to the doctor's orders, the nurses hung the IV bags in sequence on the hanging rack 6, inserted the IV bag outlet into the corresponding pluggable disposable sterile flow path interface 1, and entered the IV information on the interface of the intelligent main control unit 2.

[0028] b. Parameter settings The infusion speed and preset infusion sequence can be set via the touch screen. The system automatically verifies the channel status and displays "ready to run" on the interface.

[0029] c. Automated infusion When the device is started, the infusion is initiated in the current channel. The weight sensor 8 monitors the remaining liquid level in real time, and the status indicator light remains on.

[0030] d. Dynamic adjustments during the process • Change the infusion order: Simply drag and drop the channel numbers on the touchscreen to change the order. The changes will take effect immediately without requiring system downtime. • Increase the number of rehydration bags: Add a hanging unit → Hang the new bag → Insert the pluggable disposable sterile flow path interface 1 → Touch to activate the infusion channel → Add the bags in sequence; • Reduce the number of refill bags: Touch to deactivate the corresponding infusion channel → unplug the pluggable disposable sterile flow path interface 1 → remove the refill bag without affecting the operation of other channels.

[0031] e. Automatic bag changing and pipe flushing When the current infusion bag weight drops to the threshold, the system first activates the automatic flushing unit 3 to flush the tubing, then performs a seamless switch by opening the next bag channel first and closing the previous bag channel, automatically venting air and continuing the infusion. The flow path switching adopts an open-then-close logic, combined with the automatic flushing and anti-backflow venting components, to achieve seamless and safe infusion replenishment.

[0032] f. Empty bag warning When a single bag of IV fluid is finished, the corresponding status indicator light will illuminate. The IV bag can be replaced manually in a timely manner, or all IV bags can be replaced at once.

[0033] g. End alarm Once all fluid resuscitation is complete, the system automatically stops the infusion and triggers an audible and visual alarm to prompt the nurse to take appropriate action.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
