Description

Multifunctional Infusion and Injection Assist Device and Method Technical Field

[0001] This application relates to the technical field of medical care facilities, and in particular to a multifunctional infusion injection auxiliary device and method. Background Technology

[0002] Intravenous infusion is a common treatment method in clinical medicine, widely used in wards and outpatient / emergency infusion rooms. However, existing infusion equipment has certain inconveniences and safety hazards during operation. In continuous infusion scenarios, patients or their families need to constantly remind nurses to change the IV fluids, and nurses must ensure the correct order of the IV fluids during the change process to avoid medication errors.

[0003] Currently, the IV stands commonly used in medical facilities have relatively simple structures and functions, and cannot achieve automatic IV changing. During the IV changing process, nurses need to manually place the medication bottle onto the IV stand and ensure the correct order of medication administration. This reliance on manual operation not only increases the workload of nurses but also poses certain operational risks.

[0004] Therefore, if automated dressing changing and intelligent monitoring of the process can be implemented, it can reduce nurses' time, lower their workload, improve work efficiency, avoid accidents such as backflow and blood clotting, and shorten the patient's overall infusion time. Thus, infusion equipment with automated dressing changing capabilities has significant research value.

[0005] Chinese patent CN115192821B discloses an automatic medication infusion device with information recognition function. The patent features an adjustable information recognizer on the wall of one of the support rods. With the information recognizer, a display, and a camera mounted on it, nurses can align the medication bottle with the camera on the information recognizer when administering an infusion to a patient. The camera scans the information on the medication bottle and displays the patient's name, bed number, and ID number on the display. This technology can, to some extent, prevent medication errors.

[0006] In the aforementioned technical solutions, the nurse first scans the information of the medicine bottle on the information reader before manually placing it into the bottle shell. However, due to the reliance on the nurse's correct operation during manual placement, incorrect placement order can occur. Therefore, in actual operation, manual verification is still necessary; that is, before each IV change, the patient and medicine bottle codes and other information must be further verified. Summary of the Invention

[0007] In order to reduce the workload of nurses and improve the safety and efficiency of infusion, this application provides a multifunctional infusion injection auxiliary device and method.

[0008] On the one hand, the multifunctional infusion injection auxiliary device provided in this application adopts the following technical solution:

The automatic puncture mechanism corresponds to the puncture station of the transfer mechanism. The electrical control box is equipped with an electrical control module, a first communication module, and a first barcode scanner for identifying infusion container information. The patient interaction terminal includes a verification module for verifying patient information and a second communication module for receiving and sending patient information.

[0010] The first communication module receives patient information sent by the second communication module. The electronic control module verifies the infusion container information identified by the first barcode scanner with the patient information. After verification and matching, the control module controls the transport mechanism to transfer the infusion containers to the puncture station in sequence according to the order of the priority information in the patient information.

[0011] In one embodiment: the transfer mechanism includes a rotating turntable, an auxiliary positioning bracket fixed on the rotating turntable, and a turntable motor for driving the rotating turntable, the turntable motor being fixed to a frame; the rotating turntable includes a turntable body and a pre-installed bracket that can be switched and installed below the turntable body; the edge of the turntable body is provided with multiple upper latches, the upper latches forming openings on the turntable body; the pre-installed bracket is provided with a first lower latch for cooperating with a single port and a second lower latch for cooperating with a double port, both the first lower latch and the second lower latch forming openings on the pre-installed bracket; a support structure for the infusion container mouth to abut against is provided at an interval between the turntable body and the pre-installed bracket.

[0012] In one embodiment, the automatic puncture mechanism includes a puncture needle mounting seat for detachably mounting a puncture needle, and a puncture electric actuator for controlling the movement of the puncture needle mounting seat, the puncture electric actuator being mounted on a frame.

[0013] In one embodiment, a micro switch is provided in the mounting slot of the puncture needle mounting seat.

[0014] In one embodiment: an alignment sensing device for detecting the puncture site of the infusion container is provided between the transfer mechanism and the automatic puncture mechanism. The alignment sensing device includes a clearance seat slidably mounted on the frame, an alignment sensor mounted on the clearance seat, and a reset structure for maintaining the alignment sensor corresponding to the puncture station. The reset structure is connected to the clearance seat, and a linkage structure is provided between the clearance seat and the puncture needle mounting seat. When the puncture needle mounting seat moves upward, the alignment sensor is pushed away from the puncture station through the linkage structure.

[0015] In one embodiment: the frame is provided with a disinfection mechanism for disinfecting the puncture site of the infusion container, the disinfection mechanism including a disinfection bottle and an electromagnetic push rod for controlling the spray of the disinfection bottle.

[0016] In one embodiment: the frame is provided with a drip monitoring module for detecting the dripping state, and the drip monitoring module is located below the automatic puncture mechanism.

[0017] In one embodiment: the frame is provided with a turbidity sensor and a color sensor, the turbidity sensor being located below the automatic puncture mechanism and the color sensor being abutted against the infusion container.

[0018] In one embodiment, the auxiliary device further includes a lifting mechanism, which includes a slide rail for sliding the frame and a drive for driving the frame to slide up and down.

[0019] In one embodiment: the electronic control box is provided with a first display screen, the patient interactive terminal is provided with a second display screen, and the verification module includes at least one of a second barcode scanner, a button, and a voice interaction module.

[0020] On the other hand, the multifunctional infusion injection auxiliary method provided in this application adopts the following technical solution:

[0021] A multifunctional infusion injection assistance method includes the following steps:

[0022] S1. Obtain patient information through a patient interaction terminal. The patient information includes name, infusion information, and order information. The infusion information includes infusion type, infusion volume, infusion time, and infusion rate.

[0023] S2. Obtain patient information sent by the interactive terminal through the electronic control box, and control the rotation of the transport mechanism to obtain infusion container information;

[0024] S3. Verify the matching of infusion container information and infusion information through the electronic control box;

[0025] If the match is verified, the electronic control box controls the transfer mechanism to rotate based on the sequence information, transferring the infusion container corresponding to the first sequence to the puncture station. If the alignment sensor detects the puncture site, it controls the automatic puncture mechanism to start. If the alignment sensor does not detect the puncture site, it sends installation and adjustment information.

[0026] If a mismatch is found, a match error warning will be sent.

[0027] S4. Receive the dripping information obtained by the dripping monitoring module through the electronic control box. The dripping information includes dripping speed, dripping time, and dripping volume.

[0028] S5. Determine whether the dripping rate is within the preset range of the infusion rate through the electronic control box. If not, send adjustment information; if so, send a stop dripping signal when the infusion volume and / or infusion time is reached based on the dripping information.

[0029] S6. After the electronic control box obtains the stop drip signal, it sends a verification signal to the patient interactive terminal. After receiving the verification signal, the patient interactive terminal re-obtains the patient information and sends it to the electronic control box.

[0030] S7. The electronic control box compares the newly acquired patient information with the previous patient information. If not, a matching error warning is sent. If yes, the automatic puncture mechanism is started, the puncture needle is pulled out downwards, and the transfer mechanism is rotated based on the sequence information to transfer the infusion container corresponding to the next sequence to the puncture station. Then, the automatic puncture mechanism is started and steps S4-S7 are repeated.

[0031] S8. During steps S4-S5, the patient interaction terminal periodically sends abnormal verification information and receives feedback information, wherein the abnormal verification information includes infusion comfort and allergy information.

[0032] If the feedback message indicates abnormal infusion comfort, then a message to reduce the drip rate will be sent.

[0033] If the feedback information is an allergy message, a danger warning and a stop-drip signal will be sent.

[0034] In summary, this application has the following beneficial effects: It only requires installing the infusion container with the information page facing out onto the auxiliary positioning bracket. After the electronic control box and patient interaction terminal verify the customer information and infusion information, automatic infusion and infusion changes can be achieved without nurse intervention or verification, effectively reducing nurses' workload and improving the efficiency of the infusion process. Simultaneously, monitoring can be achieved during each infusion and throughout the infusion process, preventing infusion errors and promptly identifying and addressing problems that arise during infusion, thus improving the safety of the infusion process.

Detailed Implementation

[0055] The present application will be further described in detail below with reference to the accompanying drawings.

[0056] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] A multifunctional infusion injection auxiliary device, as shown in Figure 1, includes a frame 100, an electrical control box 200 located on one side of the frame 100, and a lifting mechanism 110 for controlling the up and down movement of the frame 100. The frame 100 is equipped with a transfer mechanism 300 for switching infusion containers 10, an automatic puncture mechanism 400 for controlling the puncture needle, an alignment sensor 600 for detecting the puncture site of the infusion container 10, a disinfection mechanism 700 for disinfecting the puncture site of the infusion container 10, a drip monitoring module 800 for detecting the drip status, a turbidity sensor 900 for detecting the turbidity of the drip, and a patient interaction terminal 500. The automatic puncture mechanism 400 corresponds to the puncture station of the transfer mechanism 300.

[0058] As shown in Figures 2 and 3, the transfer mechanism 300 includes a rotating turntable 310, an auxiliary positioning bracket 320 fixed on the rotating turntable 310, and a turntable motor 330 for driving the rotating turntable 310. The turntable motor 330 is fixed to the top plate of the frame 100 via a motor bracket, and the rotating shaft of the turntable motor 330 is connected to the rotating turntable 310. The auxiliary positioning bracket 320 is equipped with a hanging rod 321 and an infusion container holder 322. The hanging rod 321 is located at the top of the auxiliary positioning bracket 320, and the infusion container holder 322 is located below the hanging rod 321 and has a flat C-shaped opening structure. The hanging rod 321 is used for hanging the infusion container 10, and the infusion container holder 322 is used to limit the two sides of the infusion container 10, ensuring that the end face of the infusion container 10 faces outwards.

[0059] The rotating turntable 310 includes a turntable body 311 and a pre-installed bracket 312 that can be switched and installed below the turntable body 311. The edge of the turntable body 311 is provided with multiple upper brackets 3111, and the upper brackets 3111 form openings on the turntable body 311. The pre-installed bracket 312 is provided with a first lower bracket 3121 for cooperating with a single port and a second lower bracket 3122 for cooperating with a double port. Both the first lower bracket 3121 and the second lower bracket 3122 form openings on the pre-installed bracket 312. A support structure for the infusion container 10 bottle neck 20 to abut against is provided between the turntable body 311 and the pre-installed bracket 312.

[0060] As shown in Figures 4 and 5, the device includes a turntable body 311 and a pre-installed mounting bracket 312. The turntable body 311 has a circular structure. Referring to Figure 6, the edge of the turntable body 311 has multiple upper latches 3111, each forming an opening on the turntable body 311. The number of upper latches 3111 depends on the size of the turntable, and typically 3-5 are provided. In this embodiment, four upper latches 3111 are used as an example, and the four upper latches 3111 are evenly distributed around the center of the turntable body 311.

[0061] Referring to Figure 7, the pre-installed card holder 312 is provided with a first lower card slot 3121 for cooperating with a single port and a second lower card slot 3122 for cooperating with a double port. Both the first lower card slot 3121 and the second lower card slot 3122 have openings formed on the pre-installed card holder 312. In order to reduce the volume of the pre-installed card holder 312, the first lower card slot 3121 and the second lower card slot 3122 are arranged opposite to each other.

[0062] Specifically, the second lower notch 3122 includes an arc-shaped positioning groove 31221 and multiple arc-shaped support grooves 31222. The center of each of the multiple support grooves 31222 is equidistant from the center of the positioning groove 31221, and the openings of the positioning groove 31221 and the multiple support grooves 31222 are integrally connected. In use, one of the openings of the dual-port infusion container 10 is located in the positioning groove 31221, which is the actual puncture port to be used. The multiple support grooves 31222 are provided to allow the other opening space to swing, so that the orientation of the infusion container 10 is adjusted so that the side of the infusion container 10 with the label faces outwards.

[0063] The number of support grooves 31222 and the positional relationship between positioning grooves 31221 and support grooves 31222 can be determined according to the actual situation, as long as the positioning grooves 31221 and support grooves 31222 can ensure that the side of the infusion container 10 with the label can face outwards under various circumstances.

[0064] Referring to Figures 4 and 8, the pre-installed card holder 312 can be switched and installed below the turntable body 311, and the turntable body 311 and the pre-installed card holder 312 are spaced apart. The spaced arrangement forms a support structure for the infusion container 10 bottle mouth 20 to abut against. Referring to Figure 9, the stepped structure 30 of the infusion container 10 bottle mouth 20 is located between the pre-installed card holder 312 and the turntable body 311. Therefore, during puncture, the infusion container 10 bottle mouth 20 can abut against the turntable body 311 at the edge of the upper card 3111 to form support.

[0065] It should be noted that the structure of the upper latch 3111 mainly depends on the second lower latch 3122. Because the double-port infusion container 10 does not rotate around a center during adjustment, the upper latch 3111 has an irregular, heart-shaped structure as shown in Figure 6. Similarly, the design of the second lower latch 3122 also needs to further consider the restrictive effect of the upper latch 3111 on the bottle opening 20 of the infusion container 10, ensuring that the bottle opening 20 of the infusion container 10 cannot pass through the upper latch 3111.

[0066] Based on the above two objectives, the design of one positioning groove 31221 and four support grooves 31222 shown in Figure 7 is a better solution.

[0067] As shown in Figures 6 and 7, the switchable installation in this embodiment includes multiple connecting posts located at the bottom of the turntable body 311 and multiple insertion holes on the pre-installed mounting base 312 that mate with the connecting posts. Installation is achieved through the interference fit between the insertion holes and the connecting posts, making disassembly and installation convenient. When it is necessary to switch the second lower mounting slot 3122 to the first lower mounting slot 3121, the pre-installed mounting base 312 can be removed, rotated 180°, and reinstalled.

[0068] Furthermore, it should be noted that the switchable installation structure is not limited to the structure described above. It can also be a rotating connection structure, that is, the first lower slot 3121 and the second lower slot 3122 can be switched by rotating the pre-installed slot 312. However, such structures need to consider positioning and other issues, which is relatively complex. In contrast, the structure described above in this embodiment is relatively simple.

[0069] As shown in Figures 4 and 6, a limiting member 313 is rotatably installed at the edge of the opening of the turntable body 311. The limiting member 313 can rotate on the turntable body 311 to further restrict the bottle opening 20 of the infusion container 10 and prevent the bottle opening 20 from coming out of the opening of the upper latch 3111 and the lower latch.

[0070] The limiting member 313 has an oblong hole 3131. The limiting member 313 is mounted to the turntable body 311 via a locking member 3132, which provides damping. This damping by the locking member 3132 facilitates the rotation of the limiting member 313 by applying sufficient force. Simultaneously, the damping also serves a positioning function, providing a blocking effect when no external force is applied. Furthermore, the oblong hole 3131 allows for more flexible adjustment and a wider adjustment range for the limiting member 313.

[0071] The locking element 3132 can be a bolt or a bolt and spring combination structure. In this embodiment, the locking element 3132 is a hand-tightening bolt.

[0072] As shown in Figures 10 and 11, a mounting bracket 314 is detachably installed on the turntable body 311. In this embodiment, the mounting bracket 314 is inserted into the upper latch 3111 to ensure it is positioned on the upper latch 3111 and will not detach from it. The main body of the mounting bracket 314 is located between the turntable body 311 and the pre-installed bracket 312. The cross-section of the mounting bracket 314 is adapted to fit the upper latch 3111, and a retaining edge 3141 is provided at the upper edge of the mounting bracket 314 to abut against the turntable body 311.

[0073] Referring to Figure 12, the mounting bracket 314 is positioned by bolts to the turntable body 311 or by a baffle 3142 rotatably connected to the turntable body 311. In this embodiment, it is positioned by the baffle 3142. When disassembly is required, the baffle 3142 can be rotated out of the area where the mounting bracket 314 is located. Alternatively, the mounting bracket 314 can also be fixed by bolts. If bolts are used, they can be connected by locking member 3132, without the need for additional connecting bolts.

[0074] Referring to Figure 13, the mounting bracket 314 is provided with a first latch 3143, the first latch 3143 forms an opening on the mounting bracket 314, the mounting bracket 314 is provided with a single-slot locking groove 3144, the single-slot locking groove 3144 communicates with the first latch 3143, and the interlacing of the single-slot locking groove 3144 and the first latch 3143 forms a rotating locking structure, which can be used for the installation and positioning of the cross-shaped bag opening 40.

[0075] When installing the infusion container 10 with the cross-shaped bag opening 40, it is inserted into the first bayonet 3143 along the direction of the dotted line and arrow in Figure 12, and then rotated clockwise by a certain angle. Whether the rotation is clockwise or counterclockwise depends on the communication structure between the slot 3144 and the first bayonet 3143.

[0076] In addition, to facilitate the positioning of the turntable 310, a detection structure 3123 is provided on the turntable body 311 and / or the pre-installed card holder 312. In this embodiment, the detection structure 3123 is provided on the pre-installed card holder 312 as an example. The detection structure 3123 consists of two detection ears that extend along the edge of the pre-installed card holder 312.

[0077] As shown in Figure 14, some infusion containers 10 adopt a split dual-port structure. These infusion containers 10 are mostly bag-shaped, which presents certain difficulties in positioning using the aforementioned structure. Therefore, this application also provides an externally mounted vertical holder 315. The vertical holder 315 includes a connecting seat 3151 for detachable connection with the edge of the turntable body 311, and a clamping part 3152 for clamping the bag-shaped infusion container 10. Referring to Figure 15, in this embodiment, the connecting seat 3151 is a C-shaped opening that is clamped to the edge of the turntable body 311 by interference fit, and multiple C-shaped openings can be provided to adapt to different heights. In this embodiment, two are used as an example.

[0078] The clamping part 3152 is provided with a clamping port 31521 and a locking bolt 31522. The end of the locking bolt 31522 is inserted into the clamping port 31521. The clamping port 31521 is used for the skirt of the bag-shaped infusion container 10 to be inserted, and the locking bolt 31522 is used to lock and fix the skirt of the infusion container 10.

[0079] In addition, in order to better ensure that the front of the infusion container 10 faces outward, the vertical bracket 315 can be connected in multiple sets, that is, two vertical brackets 315 are connected and fixed in parallel, thereby forming two support points to ensure that the front of the infusion container 10 faces outward.

[0080] In addition, for separate dual-port infusion containers, if they can be directly installed, or if the deformable material does not affect the outward orientation of the infusion container 10, the structure of the turntable body 311 shown in the figure can be used. However, if the infusion container 10 cannot be made to face outward because one port is blocking the side of the turntable body 311, an avoidance opening can be provided on the edge of the turntable body 311 to solve the problem.

[0081] As shown in Figures 1 and 2, the electrical control box 200 is equipped with an electrical control module, a first communication module, a first barcode scanner 210 for identifying information of the infusion container 10, and a first display screen 220. The transfer mechanism 300 corresponding to the first barcode scanner 210 forms a barcode scanning station. An infrared sensor 230 is provided on the barcode scanning station for positioning, ensuring that the infusion container 10 can be accurately stopped on the barcode scanning station for scanning by the first barcode scanner 210.

[0082] The electronic control module and the first communication module are located inside the electronic control box 200. In this embodiment, the first barcode scanner 210 is located at one end of the electronic control box 200 facing the frame 100. The first display screen 220 is used to display information such as infusion container 10, patient information, and order information, wherein the order information refers to the infusion sequence.

[0083] In this case, to facilitate the removal of the infusion container 10 during IV drip administration, the puncture station and the scanning station of the first barcode scanner 210 are located at two different stations. Therefore, in actual use, after scanning the required infusion container 10, it is necessary to rotate one station, which increases the complexity of control. Therefore, the first barcode scanner 210 can also be set directly opposite the puncture station via a connecting arm. However, this setting will cause some interference. Therefore, when setting it up in this way, the connecting arm needs to be able to rotate 90 degrees so that the infusion container 10 can be easily removed.

[0084] As shown in Figures 1 and 16, the automatic puncture mechanism 400 includes a puncture needle mounting seat 410 for detachably mounting a puncture needle, and a puncture electric actuator 420 for controlling the movement of the puncture needle mounting seat 410. The puncture electric actuator 420 is mounted on the frame 100, and a connecting plate 430 is connected to the telescopic rod of the puncture electric actuator 420. The connecting plate 430 is connected to the puncture needle mounting seat 410. A guide rod 440 is also slidably mounted on the frame 100. The guide rod 440 is arranged parallel to the telescopic rod of the puncture electric actuator 420, and one end of the guide rod 440 is connected to the connecting plate 430. The puncture needle mounting base 410 is provided with a mounting groove for the puncture needle to be inserted and engaged. Referring to Figure 18, a micro switch 411 is provided in the mounting groove of the puncture needle mounting base 410. The micro switch 411 ensures that the puncture needle is engaged in place. In contrast, the engagement status of the puncture needle can be visualized by using an indicator light, an alarm, or by linking with the first display screen 220 and / or the second display screen.

[0085] Referring to Figure 17, the alignment sensing device 600 is located between the transfer mechanism 300 and the automatic puncture mechanism 400. The alignment sensing device 600 includes a relief seat 610 slidably mounted on the frame 100, an alignment sensor 620 mounted on the relief seat 610, and a reset structure 630 for maintaining the alignment sensor 620 in correspondence with the puncture station. The reset structure 630 is a tension spring, and its two ends are connected to the relief seat 610 and the frame 100, respectively.

[0086] A linkage structure is provided between the clearance seat 610 and the puncture needle mounting seat 410. The linkage structure consists of two wedge-shaped surfaces respectively located at the bottom of the clearance seat 610 and the top of the puncture needle mounting seat 410. Through the two wedge-shaped surfaces, when the puncture needle mounting seat 410 moves upward, it pushes the clearance seat 610 to slide horizontally, causing the sensor to move out of the puncture position.

[0087] As shown in Figures 16 and 17, the disinfection mechanism 700 includes a disinfection bottle 710 and an electromagnetic push rod 720 for controlling the spraying of the disinfection bottle 710. The disinfection bottle 710 is detachably mounted on the frame 100. The electromagnetic push rod 720 is fixed on the frame 100 and located at the bottom of the disinfection bottle 710. A baffle 730 is also provided on the frame 100 at the top of the disinfection bottle 710. Both ends of the disinfection bottle 710 abut against the electromagnetic push rod 720 and the baffle 730, respectively.

[0088] In addition, since the disinfection bottle 710 has a small capacity, the disinfection mechanism 700 is not limited to the setting of the disinfection bottle 710 and the electromagnetic push rod 720, and other structures capable of spraying can also be used.

[0089] As shown in Figures 1 and 16, the drip monitoring module 800 is located below the automatic puncture mechanism 400, and has a groove on it for embedding the burette.

[0090] The frame 100 is equipped with a turbidity sensor 900 and a color sensor. The turbidity sensor 900 is located below the automatic puncture mechanism 400, and the color sensor is abutted against the infusion container 10. The frame 100 detects turbidity and color and outputs abnormal information.

[0091] As shown in Figure 18, the lifting mechanism 110 includes a slide rail 111 for sliding the frame 100 and a driver 112 for driving the frame 100 to lift and slide. A slider 120 is provided on the back of the frame and is slidably mounted on the slide rail 111. The driver 112 can be electric or manual. In this embodiment, manual is taken as an example.

[0092] As shown in Figures 1 and 18, the patient interaction terminal 500 includes a verification module for verifying patient information, a second communication module for receiving and sending patient information, and a second display screen. The verification module includes at least one of a second barcode scanner, a button, and a voice interaction module. In this embodiment, a second barcode scanner, a button, and a voice interaction module are provided simultaneously.

[0093] The patient interaction terminal 500 is preferably detachably mounted on the frame 100, allowing it to be easily removed for operation when scanning is required. The patient interaction terminal 500 can be a standalone terminal device or a mobile device such as a mobile phone or tablet.

[0094] In use, the first communication module receives patient information sent by the second communication module, and the electronic control module verifies the information of the infusion container 10 identified by the first barcode scanner 210 with the patient information. After verification and matching, the control mechanism 300 transfers the infusion container 10 to the puncture station in sequence according to the order of the sequence information in the patient information.

[0095] Specifically, the multifunctional infusion injection support method includes the following steps:

[0096] S1. Obtain patient information through the patient interaction terminal 500. The patient information includes name, infusion information and order information. Among them, the infusion information includes infusion type, infusion volume, infusion time and infusion rate.

[0097] Patient information can be obtained directly from the hospital's system. In addition to the information mentioned above, information such as the patient's allergies and past infusion problems can also be obtained.

[0098] S2. The patient information sent by the interactive terminal is obtained through the electronic control box 200, and the transport mechanism 300 is rotated to obtain the information of the infusion container 10.

[0099] The acquired patient information can be directly displayed on the first display screen 220, which can be viewed and verified by nurses and patients.

[0100] S3. Verify the information of the infusion container 10 and the infusion information through the electronic control box 200 to see if they match.

[0101] If the match is verified, the electronic control box 200 controls the transfer mechanism 300 to rotate based on the sequence information, and transfers the infusion container 10 corresponding to the first sequence to the puncture station. If the alignment sensor 620 detects the puncture site, it controls the automatic puncture mechanism 400 to start. If the alignment sensor does not detect the puncture site, it sends installation and adjustment information.

[0102] If a mismatch is found, a match error warning will be sent.

[0103] During this step, the verification process can be directly displayed on the first display screen 220. For example, if the verification is correct, a checkmark will be placed or the text will turn green. If the verification is incorrect, an X will be placed or the text will turn red. This allows nurses and patients to directly check the matching status and correct errors through the first display screen 220.

[0104] S4. The electrical control box 200 receives the dripping information obtained by the dripping monitoring module 800, which includes the dripping speed, dripping time and dripping volume.

[0105] The drip information can be displayed on the first display screen 220 and / or the second display screen.

[0106] S5. The electronic control box 200 determines whether the dripping speed is within the preset range of the infusion speed. If not, it sends adjustment information; if so, it sends a stop dripping signal when the infusion volume and / or infusion time is reached based on the dripping information.

[0107] In this step, the preset infusion rate in the patient information is usually a range value. Drip control is divided into manual and automatic depending on the controller. Manual control uses the controller built into the drip tube, while automatic control uses an electronically controlled controller on the auxiliary device. However, since the infusion container 10 needs to be removed for purposes such as going to the toilet or walking, the cost of an electronically controlled controller is relatively high, so manual control is used in most cases. Manual control has lower accuracy, and some patients may adjust it themselves. Therefore, monitoring the drip rate can provide a reference for these patients and prevent unexpected situations.

[0108] S6. After the electronic control box 200 obtains the stop drip signal, it sends a verification signal to the patient interaction terminal 500. After receiving the verification signal, the patient interaction terminal 500 re-obtains the patient information and sends it to the electronic control box 200.

[0109] S7. The electronic control box 200 compares the newly acquired patient information with the previous patient information. If not, it sends a matching error warning. If yes, it controls the automatic puncture mechanism (400) to start, pulls out the puncture needle, controls the transfer mechanism 300 to rotate based on the sequence information, and then controls the automatic puncture mechanism 400 to start and repeat steps S4-S7.

[0110] Information is checked before each infusion to prevent multiple people from removing the infusion container and accidentally hanging it incorrectly. This allows for timely detection and adjustment, avoiding medical accidents.

[0111] During steps S8 and S4-S5, the patient interaction terminal 500 periodically sends abnormal verification information and receives feedback information, including infusion comfort and allergy information.

[0112] If the feedback message indicates abnormal infusion comfort, then a message to reduce the drip rate will be sent.

[0113] If the feedback information is an allergy message, a danger warning and a stop-drip signal will be sent.

[0114] In this step, the system automatically monitors the infusion process in real time. For example, it can collect the customer's status by displaying text confirmation on a second screen or by issuing voice inquiries at regular intervals through a voice interaction module. If the collected feedback indicates that the infusion is too fast and causing discomfort, it can remind the customer to slow down the infusion rate. Furthermore, if symptoms such as fever, rash, hemolysis, or shock occur, the system can detect them promptly and stop the infusion.

[0115] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
