[0044] A plurality of electromagnetic liquid outlet mechanisms are arranged on the first partition plate 25, and the plurality of electromagnetic liquid outlet mechanisms correspond to the plurality of sub-drug liquid chambers one by one, and the electromagnetic liquid outlet mechanisms are used to control the on-off state of the sub-drug liquid chambers and the main drug liquid chamber 29;

[0045] A plurality of liquid inlet pipes are arranged on the automatic infusion box 20, and the plurality of liquid inlet pipes correspond to and are connected with the plurality of sub-medicine liquid chambers one by one;

[0046] The control box 30 is connected to the plurality of electromagnetic liquid outlet mechanisms. A PLC controller is provided in the control box 30 for controlling the on and off states of the plurality of electromagnets 70 .

[0047] By setting up a plurality of sub-medicine liquid chambers connected to the main medicine liquid chamber 29 in the automatic infusion box 20, the medicine liquid can be input into the plurality of sub-medicine liquid chambers through a plurality of liquid inlet tubes, and the on-off state between the sub-medicine liquid chamber and the main medicine liquid chamber 29 is controlled by the electromagnetic liquid outlet mechanism, so that a variety of different medicine liquids are automatically delivered in the order of infusion, which not only reduces the workload of medical staff but also avoids medical accidents caused by failure to change the liquid in time.

[0048] Furthermore, the plurality of sub-drug liquid chambers include a first drug liquid chamber 26 , a second drug liquid chamber 27 and a third drug liquid chamber 28 .

[0049] Furthermore, the plurality of liquid inlet tubes include a first liquid inlet tube 21 connected to the first liquid chamber 26 , a second liquid inlet tube 22 connected to the second liquid chamber 27 , and a third liquid inlet tube 23 connected to the third liquid chamber 28 .

[0050] Furthermore, a liquid outlet 210 for connecting the infusion tube 10 and the main liquid chamber 29 is provided on the automatic infusion box.

[0051] In one embodiment of the present invention, the electromagnetic liquid discharging mechanism comprises:

[0052] A communication port 252 is provided on the first partition plate 25. The communication port 252 is used to connect the sub-drug liquid chamber and the main drug liquid chamber 29. The diameter of the communication port 252 is 1-2 cm.

[0053] The ball plug 50 is disposed in the communication port 252. The ball plug 50 is a hollow soft plastic ball with a wall thickness of 2-3 mm.

[0054] The electromagnetic pusher 60 is disposed at one side of the communication port 252, and the electromagnetic pusher 60 abuts against the ball plug 50;

[0055] The electromagnet 70 is disposed on a side of the communication port 252 away from the electromagnetic pusher 60 , and is used to attract the electromagnetic pusher 60 to move.

[0056] The electromagnetic pusher 60 is attracted by the electromagnet 70 to move toward the electromagnet 70 , so that the electromagnetic pusher 60 pushes the spherical plug 50 to deform, thereby making the communication port 252 communicate with the main drug liquid chamber 29 , so that the drug liquid can enter the main drug liquid chamber 29 .

[0057] Furthermore, one side of the communication port 252 is connected to a first placement groove 251 for placing the electromagnetic pusher 60 , and the side of the communication port 252 away from the first placement groove 251 is connected to a second placement groove 253 for placing the electromagnet 70 .

[0058] In one embodiment of the present invention, the electromagnetic pusher 60 includes:

[0059] Casing 61;

[0060] A push rod 62 is slidably disposed in the sleeve 61;

[0061] A metal block 63 is disposed at the end of the push rod 62 facing the electromagnet 70;

[0062] The spring 64 is fixedly connected between the push rod 62 and the sleeve 61 .

[0063] When the electromagnet 70 is energized, the metal block 63 is attracted to move toward the electromagnet 70, so that the push rod 62 slides along the sleeve 61, so that the push rod 62 can push the ball plug 50 to deform, and the spring 64 can facilitate the automatic reset of the push rod 62 after the electromagnet 70 is de-energized.

[0064] In one embodiment of the present invention, a plurality of batteries are further included, which are disposed on the automatic infusion box 20 , and the plurality of batteries are electrically connected to the plurality of electromagnets 70 via wires 80 .

[0065] Furthermore, the plurality of batteries include a first battery 44 and a second battery 45 , the first battery 44 is electrically connected to the electromagnet 70 at the first liquid medicine chamber 26 via a wire 80 , and the second battery 45 is electrically connected to the electromagnets 70 at the second liquid medicine chamber 27 and the third liquid medicine chamber 28 via a wire 80 .

[0066] Furthermore, the first battery 44 and the second battery 45 are both rechargeable lithium batteries or storage batteries.

[0067] Furthermore, a side of the second placement groove 253 away from the connecting port 252 is connected to a third placement groove 254 for placing the wire 80 .

[0068] Furthermore, it should be noted that the first placement groove 251 in the third medicine liquid chamber 28 is located on the right side of the connecting port 252, and the second placement groove 253 is located on the left side of the connecting port 252, because the pushing member 60 in the third medicine liquid chamber 28 is located on the right side of the ball plug 50 when installed, and the electromagnet 70 is located on the left side of the ball plug 50.

[0069] In one embodiment of the present invention, a plurality of second partitions 46 are fixedly connected between the top surface of the first partition 25 and the inner bottom surface of the automatic infusion box 20 to form a plurality of sub-drug liquid chambers.

[0070] Furthermore, there are two second partitions 46 , and a first mounting groove 40 and a second mounting groove 41 are respectively opened on the two second partitions 46 . The first battery 44 is assembled in the first mounting groove 40 and closed by the first cover plate 42 . The second battery 45 is assembled in the second mounting groove 41 and closed by the second cover plate 43 .

[0071] The first installation slot 40 is detachably connected to the first cover plate 42 , and the second installation slot 41 is detachably connected to the second cover plate 43 . The disassembly and assembly of the first cover plate 42 and the second cover plate 43 can facilitate the charging of the first battery 44 and the second battery 45 at a later stage.

[0072] In one embodiment of the present invention, a plurality of flow sensors are further included, which are respectively arranged on a plurality of liquid inlet pipes.

[0073] The flow sensor is used to monitor the flow rate of the liquid out of the liquid inlet pipe.

[0074] The plurality of flow sensors include a first flow sensor 211 disposed on the first liquid inlet pipe 21 , a second flow sensor 221 disposed on the second liquid inlet pipe 22 , and a third flow sensor 231 disposed on the third liquid inlet pipe 23 .

[0075] In one embodiment of the present invention, a plurality of bottle stopper piercing heads 90 are further included, which are respectively arranged on a plurality of liquid inlet tubes.

[0076] The bottle stopper piercing head 90 is used to connect with the medicine bottle.

[0077] In one embodiment of the present invention, a strap 24 is further included and arranged on the automatic infusion box 20 .

[0078] The binding belt 24 is used to fix the automatic infusion box 20 on the infusion stand.

[0079] In one embodiment of the present invention, a drip pot 11 and a flow rate regulator 12 are also provided on the infusion tube 10 .

[0080] In one embodiment of the present invention, a drug liquid filter 13 is further included, which is arranged on the infusion tube 10 and is located between the flow rate regulator 12 and the needle 14 .

[0081] Further, it should be noted that after the liquid medicine in the first liquid inlet pipe 21 is delivered, the communication port 252 on the second liquid medicine chamber 27 is opened after waiting for 5-7 seconds, so as to reserve some time for the remaining liquid medicine in the first liquid medicine chamber 26 to flow into the main liquid medicine chamber 29, thereby reducing the waste of liquid medicine. At the same time, it also reserves some time for the liquid medicine in the main liquid medicine chamber 29 to be delivered to the drip pot 11, thereby avoiding direct mixing of the liquid medicine. Similarly, after the liquid medicine in the second liquid inlet pipe 22 is delivered, the communication port 252 on the third liquid medicine chamber 28 is opened after waiting for 5-7 seconds.

[0082] Since the time interval is very short and there is still a certain amount of liquid medicine remaining in the infusion tube 10 and the drip pot 11, it can be ensured that there is always liquid medicine in the infusion tube 10, ensuring the smoothness of the patient's infusion and avoiding the situation of blood return.

[0083] Directions:

[0084] Step 1: The first liquid inlet tube 21 is first inserted into the infusion bottle or infusion bag through the bottle stopper puncture head 90, and then hung on the infusion stand. The automatic infusion box 20 can be fixed to the infusion pole by the strap 24 to ensure its stability; the flow rate of the liquid medicine can be adjusted by the flow rate regulator 12, so that the liquid medicine flows through the first liquid inlet tube 21 and enters the first liquid medicine cavity 26. At this time, the first flow sensor 211 receives the signal and transmits the signal to the control box 30, and the control box 30 controls the first battery 44 to supply the first liquid medicine cavity 26. The electromagnet 70 on the housing 60 is energized. When the electromagnet 70 is energized, the metal block 63 can be magnetically attracted, so that the push rod 62 extends from the sleeve 61, thereby squeezing the ball plug 50 and deforming it, thereby opening the communication port 252 on the first liquid medicine chamber 26, and the liquid medicine flows into the main liquid medicine chamber 29, and enters the drip pot 11 through the infusion tube 10. The infusion tube 10 is closed through the flow rate regulator 12, and the needle 14 is used to insert the needle into the patient's vein, and then the flow rate regulator 12 is opened to achieve intravenous infusion of the patient;

[0085] Step 2: Then the second liquid inlet tube 22 and the third liquid inlet tube 23 are respectively inserted into other infusion bottles or infusion bags through the bottle stopper puncture head 90, and the liquid medicine flows into the second liquid medicine cavity 27 and the third liquid medicine cavity 28 respectively. Since the liquid medicine is always flowing in the first liquid inlet tube 21, the first flow sensor 211 always detects the signal, so the connecting port 252 on the second liquid medicine cavity 27 and the connecting port 252 on the third liquid medicine cavity 28 are always in a closed state;

[0086] Step 3: After the liquid medicine in the first liquid inlet pipe 21 has been circulated, after waiting for 5-7 seconds, the control box 30 controls the second battery 45 to energize the electromagnet 70 on the second liquid medicine chamber 27. When the electromagnet 70 is energized, the metal block 63 can be magnetically adsorbed, so that the push rod 62 extends from the sleeve 61 to squeeze the ball plug 50 and deform it, thereby opening the communication port 252 on the second liquid medicine chamber 57, and the liquid medicine flows into the main liquid medicine chamber 29. At the same time, the first battery 44 cuts off the power to the electromagnet 70 on the first liquid medicine chamber 26, the push rod 62 is reset, and the ball plug 50 recovers its deformation, and the communication port 252 on the first liquid medicine chamber 26 is closed;

[0087] Step 4: When the medicine in the second liquid inlet pipe 22 has been circulated, after waiting for 5-7s, the control box 30 controls the second battery 45 to energize the electromagnet 70 on the third medicine liquid chamber 28. When the electromagnet 70 is energized, the metal block 63 can be magnetically adsorbed, so that the push rod 62 extends from the sleeve 61 to squeeze the spherical plug 50 and deform it, thereby opening the connecting port 252 on the third medicine liquid chamber 28, and the medicine flows into the main medicine liquid chamber 29. At the same time, the second battery 45 cuts off the power to the electromagnet 70 on the second medicine liquid chamber 27, the push rod 62 is reset, and the spherical plug 50 resumes its deformation, and the connecting port 252 on the second medicine liquid chamber 27 is closed.

[0088] It should be noted that the connecting port 252 on the first liquid medicine chamber 26, the connecting port 252 on the second liquid medicine chamber 27, and the connecting port 252 on the third liquid medicine chamber 28 are opened in sequence. After there is no liquid medicine in the first liquid inlet pipe 21, when there is liquid medicine in the second liquid inlet pipe 22 and the third liquid inlet pipe 23, the connecting port 252 on the second liquid medicine chamber 27 will be opened first in sequence.

[0089] Therefore, the numbers 1, 2, and 3 can be sequentially pasted on the first liquid inlet tube 21, the second liquid inlet tube 22, and the third liquid inlet tube 23, and when the patient is infused, the infusion bag can be inserted into the liquid inlet tube in the order of the infusion.

[0090] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0091] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
