Technical Field

[0001] This utility model relates to the technical field of drug delivery, and in particular to the technical field of drug delivery robots. Background Technology

[0002] In modern healthcare systems, medication delivery to inpatients is a core component of clinical nursing care, directly impacting treatment timeliness and medication safety. However, due to the typical division of inpatient wards by floor or department, and the fact that a single nurse often needs to care for 10-20 inpatients daily, the current mainstream manual medication delivery model still faces numerous insurmountable technical challenges and efficiency bottlenecks. Firstly, manual medication delivery is labor-intensive and inefficient (nurses must first verify medications against doctor's orders at the nurses' station, then carry the medication tray to each bed, waiting for patients to confirm their identity and cooperate with medication administration; if patients temporarily leave or change beds, repeated trips and adjustments may be necessary). This not only... This process encroaches on nurses' time for core tasks such as patient observation and nursing procedures. It can also lead to medication delays due to cumbersome procedures, affecting treatment progress and making it difficult to meet the medication needs of inpatient wards with "multiple beds, multiple time periods, and multiple medication categories." Secondly, manual medication delivery carries a higher risk of error (in manual operation, nurses must simultaneously handle "information verification" and "path planning," making them prone to errors due to fatigue and distraction), making it difficult to ensure medication safety. Finally, manual medication delivery has weak information traceability capabilities, making it difficult to achieve the management requirement of "full-process traceability" (in the current inpatient medication delivery process, the "dispensing-receiving" stage of medication mainly relies on nurses' handwritten records, which often suffer from "untimely and incomplete" information records).

[0003] To alleviate the burden of medication delivery for nurses, a number of medication delivery robots have gradually emerged on the market that can receive medication from nurses and then deliver it to wards autonomously. Examples include an intelligent medication delivery robot with publication number CN107616889A and a medication delivery robot for isolation wards with publication number CN113103243A. However, these medication delivery robots cannot lock and isolate medications for different patients, which may lead to patients taking the wrong or missing medications.

[0004] In summary, the traditional inpatient medication delivery model, due to its over-reliance on manual operation, has significant shortcomings in terms of efficiency, safety, and traceability, making it difficult to meet the development needs of modern hospitals for "efficient nursing, safe medication, and refined management." Furthermore, the accuracy of existing medication delivery robots needs improvement. Therefore, developing an automated device that can replace manual labor to achieve precise drug delivery has become an urgent technical problem to be solved in the current medical and nursing field. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the existing technology and propose a precision delivery robot that can assist nurses in accurately delivering medicines to the bedside.

[0006] To achieve the above objectives, this utility model proposes a precision delivery medicine delivery robot, comprising a body, a control display, an intelligent medicine cabinet, and a barcode scanner. The body can walk on the ground while avoiding obstacles and simultaneously carries the control display and the intelligent medicine cabinet. The intelligent medicine cabinet has several independent cabinet openings that can be opened or locked individually. The barcode scanner is installed on the intelligent medicine cabinet and can open a designated cabinet opening by scanning a barcode. The body has a central controller that is electrically connected to the control display, the intelligent medicine cabinet, and the barcode scanner.

[0007] Preferably, the barcode scanner and each cabinet opening are respectively located on the front side of the smart medicine cabinet. The smart medicine cabinet also has an inspection port located on the rear side, which is connected to each cabinet opening and is detachably closed by an inspection cover.

[0008] Preferably, the front side of the smart medicine cabinet also has a forward-extending protrusion, and the barcode scanner is installed on the protrusion.

[0009] Preferably, the intelligent medicine cabinet has at least two different sizes of cabinet openings or all cabinet openings are of the same size.

[0010] Preferably, the control display includes a touch screen and a stand. The touch screen is indirectly connected to the body through the stand. The stand is telescopically adjustable in height, and the touch screen can rotate relative to the stand by a specified angle.

[0011] Preferably, the housing is also equipped with a sensor light and / or a buzzer that is electrically connected to the central controller.

[0012] Preferably, the device moves between the nurse's end and the patient's end by means of a sensor obstacle avoidance mechanism and a motion drive mechanism.

[0013] Preferably, the sensor obstacle avoidance mechanism is one or a combination of infrared obstacle avoidance sensors, ultrasonic obstacle avoidance sensors and visual obstacle avoidance sensors.

[0014] Preferably, the mobile drive mechanism includes a traveling wheel, an auxiliary wheel, and a reversing wheel. The traveling wheel is distributed on the left and right sides of the bottom surface of the machine body and is driven to roll by a first motor. The reversing wheel is arranged on the front side of the bottom surface of the machine body and is driven to turn by a second motor. The auxiliary wheel is evenly distributed on the edge of the bottom surface of the machine body.

[0015] Preferably, the diameter of the traveling wheel is larger than the diameter of the auxiliary wheel, and the diameter of the auxiliary wheel is larger than the diameter of the reversing wheel.

[0016] The beneficial effects of this utility model are:

[0017] 1) Significantly reduces nurses' workload and improves medication delivery efficiency: This utility model, through its autonomous obstacle avoidance and walking function, can replace nurses in completing the entire process from "medication retrieval at the nurse's end" to "medication delivery at the patient's end." Nurses only need to complete medication entry and cabinet allocation at the nurses' station by controlling the monitor, without having to go to each ward, significantly reducing unnecessary walking time. At the same time, the multi-independent cabinet design of the intelligent medicine cabinet supports batch pre-storage of "one patient, one cabinet," which can be combined with the precise unlocking function of the barcode scanner to achieve simultaneous delivery of medications to multiple patients, greatly improving medication delivery efficiency. It is especially suitable for the medication needs of "multiple beds, multiple time periods, and multiple categories" in inpatient departments, allowing nurses to devote more time to core tasks such as patient observation and nursing operations.

[0018] 2) Building a dual security system to reduce the risk of medication errors: On the one hand, this utility model can achieve physical isolation of different patients' medications through several independent cabinet openings of the smart medicine cabinet, avoiding the risk of mis-taking caused by mixed storage of medications. On the other hand, the design of binding the barcode scanner to the cabinet opening also requires patients to scan the code through a special medium (such as a wristband) to open the corresponding cabinet opening, forming a closed loop of identity verification and eliminating the situation of "patients taking the wrong medicine and others taking the wrong medicine" from the source. In addition, the control display can record the binding information of "medicine-cabinet-patient" in real time, allowing patients to check the bed and medicine name displayed on the touch screen during the medication collection period, further reducing the risk of medication errors and ensuring medication safety.

[0019] 3) Achieving full-process information traceability to facilitate refined hospital management: This utility model constructs a full-process information traceability system for drug delivery through the electrical connection of a central controller with a control display, intelligent medicine cabinet, and barcode scanner. Specifically, when a nurse enters medication information, the system can automatically record information such as the drug name, specifications, quantity, corresponding patient, assigned cabinet, and entry time. When a patient picks up their medication, the unlocking action triggered by the barcode scanner will automatically be associated with the "medication time and the identity of the person picking up the medication" (associated through the barcode scanning medium). This enables the full-process traceability of medication from entry to pickup, providing data support for hospital drug management and nursing quality assessment, and helping hospitals achieve refined management.

[0020] 4) Multi-dimensional stable support, while ensuring precise steering control: In this utility model, the large wheels (walking wheels) located on the left and right sides can directly widen the robot's "lateral support width", the medium-sized wheels (auxiliary wheels) symmetrically distributed on the edge can fill the lateral support gap to further prevent the side-tipping phenomenon, and the small wheels (reversing wheels) located on the central axis can not only serve as steering guide wheels but also bear part of the front weight, thus enabling the robot to have both high anti-tipping and swaying performance and high steering flexibility.

[0021] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0026] See Figures 1 to 3 This utility model relates to a precision delivery robot for medicines, comprising a body 1, a control display 2, an intelligent medicine cabinet 3, and a barcode scanner 4. The body 1 can move on the ground while avoiding obstacles and simultaneously carries the control display 2 and the intelligent medicine cabinet 3. The intelligent medicine cabinet 3 has several independent cabinet openings 31 that can be opened or locked individually. The barcode scanner 4 is installed on the intelligent medicine cabinet 3 and can open a designated cabinet opening 31 by scanning a barcode. The body 1 has a central controller that is electrically connected to the control display 2, the intelligent medicine cabinet 3, and the barcode scanner 4.

[0027] The barcode scanner 4 and each cabinet opening 31 are respectively located on the front side of the intelligent medicine cabinet 3. The intelligent medicine cabinet 3 also has a maintenance port located on the rear side, which is connected to each cabinet opening 31 and is detachably closed by a maintenance cover 32. Since the intelligent medicine cabinet 3 places the barcode scanner 4 and each cabinet opening 31 on the front side, it is more in line with the operating habits of medical staff and patients, and can avoid the inconvenience caused by the scattered distribution of components. At the same time, the rear maintenance design of the intelligent medicine cabinet 3 also solves the maintenance problem of traditional cabinets where the entire cabinet needs to be disassembled when a single cabinet opening 31 fails. Specifically, when a cabinet opening 31 experiences an electronic lock failure or requires deep cleaning, maintenance personnel do not need to disassemble the entire intelligent medicine cabinet 3, but only need to open the rear maintenance cover 32 to directly inspect or clean the target cabinet opening 31, which greatly reduces the difficulty of maintenance and reduces equipment downtime.

[0028] The front side of the intelligent medicine cabinet 3 also has a forward-extending protrusion 33, and the barcode scanner 4 is installed on the protrusion 33. The forward-extending design makes the position of the barcode scanner 4 more prominent, which makes it easier for patients or nurses to quickly locate the scanning area and improves the efficiency of operation. In addition, the barcode scanner 4 can be used in conjunction with the barcode gun 5.

[0029] The intelligent medicine cabinet 3 is equipped with at least two different sizes of cabinet openings 31 or all cabinet openings 31 are of uniform size. The size-differentiated design can meet the storage needs of different specifications of medicines (such as bottled liquid medicine, boxed tablets and injections), and avoid the phenomenon of "large medicines not being able to fit and small medicines being easy to shake" caused by the uniform size of the cabinet openings 31, thus improving the adaptability of medicine storage. The uniform size of the cabinet openings 31 can improve the neatness of the appearance.

[0030] The control display 2 includes a touch screen 21 and a bracket 22. The touch screen 21 is indirectly connected to the body 1 through the bracket 22. The bracket 22 is telescopically adjustable in height, and the touch screen 21 can rotate relative to the bracket 22 by a specified angle. Specifically, the vertical extension and retraction of the bracket 22 can be achieved by adjusting the depth of the screw screw into the screw sleeve, or by inserting and tightening several bracket rods arranged from top to bottom with bolts and nuts to achieve the vertical extension and retraction of the bracket 22.

[0031] The body 1 is also equipped with a sensor light and / or a buzzer that is electrically connected to the central controller; that is, the sensor light and buzzer equipped on the body 1 can provide intuitive status prompts through "light color + buzzer status".

[0032] The body 1 moves between the nurse's end and the patient's end by avoiding obstacles through a sensor obstacle avoidance mechanism and a motion drive mechanism.

[0033] The obstacle avoidance mechanism is one or a combination of infrared obstacle avoidance sensors, ultrasonic obstacle avoidance sensors, and visual obstacle avoidance sensors.

[0034] The mobile drive mechanism includes a walking wheel 11, an auxiliary wheel 12, and a reversing wheel 13. The walking wheel 11 is distributed on the left and right sides of the bottom surface of the body 1 and is driven to roll by a first motor. The reversing wheel 13 is arranged on the front side of the bottom surface of the body 1 and is driven to turn by a second motor. The auxiliary wheel 12 is evenly distributed on the bottom edge of the body 1.

[0035] The diameter of the traveling wheel 11 is greater than the diameter of the auxiliary wheel 12, and the diameter of the auxiliary wheel 12 is greater than the diameter of the reversing wheel 13.

[0036] The working process of this utility model:

[0037] First, the nurse logs in to their account via touchscreen 21, then scans the barcode on scanner 4 and selects the compartment type on the touchscreen. After the designated compartment 31 opens, the nurse places the medication into the compartment and enters information such as bed number, patient, compartment number, and medication name. This process is repeated until all medications are placed. Next, the nurse selects medications to be delivered in batches via touchscreen 21. Then, the machine body 1 moves to each patient's location one by one using a sensor obstacle avoidance mechanism and a motion drive mechanism. Patients can scan the barcode on scanner 4 using their wristband to open the corresponding compartment 31 and retrieve the required medication. During this process, a sensor light and / or buzzer can indicate the matching result through light color and / or buzzer status (e.g., a green light indicates the medication is available; a buzzer indicates no medication is available). Furthermore, during medication retrieval, touchscreen 21 can display real-time medication information (such as bed number, patient, compartment number, and medication name) for patient verification.

[0038] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
