Description

Technical Field

[0001] This invention belongs to the field of intelligent management technology for medical supplies, specifically relating to a patient gown receiving and issuing management system and method. Background Technology

[0002] In the daily operations of medical institutions, the distribution and collection of patient gowns is a crucial aspect of patient admission and inpatient care management. Existing patient gown management models largely rely on manual registration, which is time-consuming and labor-intensive. Furthermore, the lack of effective verification of the link between patient identity and clothing makes it difficult to confirm the legality of returned clothing during the replacement process, potentially leading to cross-infection risks or asset loss due to lost clothing. Simultaneously, current distribution methods typically use fixed sizes or rely solely on experience, lacking precise matching methods based on real-time patient body parameters and failing to flexibly adjust to changes in patient body shape, impacting comfort and treatment efficiency. Therefore, there is an urgent need for a patient gown distribution and collection management solution that enables accurate identity verification and dynamic size adaptation. Summary of the Invention

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of the present invention is to provide a patient gown receiving and issuing management system and method.

The validity verification includes: Obtain the identity information associated with the unique identifier, and compare the associated identity information with the patient's identity information for consistency; if the comparison matches, the verification passes; if the comparison does not match, the verification fails.

[0005] Preferably, the process of distributing medical dresses according to the patient's current size requirements specifically includes: Provide the patient with a size change option; In response to the patient's choice to change size, the patient's body parameters are re-collected and a new target size is determined based on the re-collected body parameters. In response to the patient's choice not to change the size, the patient's historical size record is retrieved, and the target size is determined according to the historical size record; The disease number is divided into different sizes according to the determined target size.

[0006] A patient gown receiving and dispensing management system for performing the method described above includes at least one control cabinet and at least one storage cabinet; The control cabinet is equipped with a control unit, an identification unit, and a data acquisition unit; the identification unit is used to acquire the patient's identity information and determine the patient's medical treatment type based on the identity information; the data acquisition unit is used to collect the patient's physical parameters; and the control unit is used to execute the logic control of the initial distribution process and the replacement process. The storage cabinet is equipped with a conveying unit and a recycling unit; The conveying unit includes a conveyor belt and a drive wheel assembly that is driven and connected to the conveyor belt. Multiple separators are spaced apart on the outer wall of the conveyor belt, and a storage slot for storing clean hospital gowns is formed between adjacent separators. An accommodating space is formed on the inner side of the conveyor belt. The recycling unit is located within the accommodating space and includes multiple identification elements and a movable part that can at least partially extend out of the storage cabinet. The movable part is provided with multiple recycling slots for storing old hospital gowns. The identification elements correspond to the positions of the recycling slots and are used to identify the unique identification mark on the old hospital gown in the corresponding recycling slot. The storage cabinet door is provided with a retrieval port and a recycling port. The retrieval port is connected to one of the storage slots of the conveying unit, and the recycling port is located at the position of the movable part, so that the movable part can extend at least partially out of the storage cabinet through the recycling port.

[0007] Preferably, the recycling unit further includes a fixed sleeve fitted over the outside of the movable part, and the identification element is disposed inside the fixed sleeve; a sealing element is provided at one end of the fixed sleeve near the cabinet door of the storage cabinet, and the sealing element is used to close the gap between the fixed sleeve and the cabinet door so as to isolate the storage tank and the recycling tank from each other.

[0008] Preferably, a partition is provided between adjacent recycling tanks, and the partition is provided with a disinfection device for disinfecting the old hospital gowns stored in the recycling tanks; the disinfection device is one or more of ultraviolet disinfection lamps, ozone generators, plasma disinfection devices or heating disinfection devices.

[0009] Preferably, the movable component is slidably connected to the fixed sleeve via an electric slide rail assembly; the electric slide rail assembly includes a linearly driven electric guide rail and an electric slider.

[0010] Preferably, the data acquisition unit includes one or more of the following: a height measurement module, a weight measurement module, a dimension measurement module, and a human-computer interaction input module; the height measurement module is an ultrasonic rangefinder or an infrared rangefinder installed on the control cabinet, the weight measurement module is an electronic scale installed at the bottom or front of the control cabinet, the dimension measurement module is an electronic flexible ruler installed on the control cabinet, and the human-computer interaction input module is a touch screen.

[0011] Preferably, the control cabinet is provided with a drive device and a storage drawer that is pulsatorically connected to the drive device, and the dimension measurement module is housed in the storage drawer; the drive device, in response to the activation of the data acquisition unit, drives the storage drawer to extend out of the control cabinet.

[0012] Preferably, the storage drawer is equipped with a detection device for detecting the unique mark of the dimension measurement module; the drive device normally drives the storage drawer to retract into the control cabinet in response to the detection result of the detection device.

[0013] It should be noted that when the dimension measurement module is taken out of the storage drawer, a preset countdown is started. If the dimension measurement module is not returned to the storage drawer after the preset countdown ends, an abnormality mark is executed on the current patient to prevent the dimension measurement module from being lost.

[0014] Preferably, the retrieval port is provided with an automatically opening and closing retrieval door, which is electrically connected to the control unit. The control unit controls the retrieval door to open in response to a disease identification service command and controls the retrieval door to close after a preset delay time.

[0015] Compared with the prior art, the present invention has the following advantages: (1) This invention provides a method for managing the receipt and distribution of hospital gowns, distinguishing between first-time and non-first-time patients. For first-time patients, a mapping relationship between body parameters and sizes is directly established and initial binding is completed; for non-first-time patients, a unique identity verification mechanism is introduced to ensure that the old hospital gowns collected are indeed used by the patient, preventing misreceipt or malicious replacement. At the same time, after verification, the old identity is promptly unbound and permissions are assigned to the new gowns, thereby effectively forming a complete closed-loop management of clothing, and thus improving the accuracy and security of medical asset management.

[0016] (2) This invention provides a patient gown receiving and dispensing management system, which integrates identity recognition, data collection, clean clothing conveying and soiled clothing recycling through the mutual coordination of control cabinet and storage cabinet; in particular, the recycling unit is arranged by utilizing the accommodating space formed on the inner side of the conveyor belt, and the cooperation of fixed sleeve and sealing element effectively realizes the three-dimensional separation of clean and soiled paths in space, thereby preventing pathogens carried by old clothes from contaminating clean patient gowns; the extendable setting of movable parts makes it convenient for patients to put in old clothes, while the built-in setting of identification elements ensures automatic verification during the recycling process.

[0017] (3) In the system of the present invention, an independent disinfection device is set inside the recycling tank so that the old clothes can be disinfected immediately after entering the recycling tank, thereby further reducing the risk of cross-infection in the process of receiving and sending.

[0018] (4) In the system of the present invention, the return status of the dimension measurement module is confirmed by the detection device. The drawer is only allowed to close after the module is detected to be correctly returned, which effectively prevents squeezing damage or loss caused by the module not being returned to its original position.

It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0021] Example 1 like Figure 1 As shown, this embodiment provides a method for managing the receipt and distribution of patient gowns, including: S100. Obtain the patient's identity information and determine the patient's visit type based on the identity information, wherein the visit type includes first visit and non-first visit.

[0022] Specifically, identity information can be obtained in various ways, such as by capturing facial features through a facial recognition camera, reading the barcode or RFID tag on the hospital wristband through a card reader, or manually entering the hospital number through a human-computer interaction interface. After obtaining the identity information, the system will automatically check the background database for historical clothing binding records or transaction records for the patient. If no relevant historical records are found in the database or the binding status is empty, it is determined to be a first visit; if valid historical binding records or recent transaction records are found, it is determined to be a subsequent visit.

[0023] S200. If the patient is visiting for the first time, the initial distribution process is executed, which includes: collecting the patient's body parameters, determining the corresponding target size based on the body parameters, and distributing medical certificates to the patient based on the target size.

[0024] Specifically, for patients visiting for the first time, the system has not yet established their body shape data profile, so it is necessary to collect body parameters in real time. Body parameters typically include, but are not limited to, key dimensions such as height, weight, chest circumference, and waist circumference. When determining the target size, the system can use a preset size mapping table for lookup matching, or it can use a built-in recommendation algorithm to calculate the best fit size based on multi-dimensional parameters. For example, when a patient is 175cm tall and weighs 70kg, the system automatically matches a size L hospital gown. After determining the size, the system sends a distribution command to the storage cabinet, driving the conveyor unit to deliver a clean hospital gown of the corresponding size to the retrieval port.

[0025] This step completes the initial digital binding of patient individual characteristics with clothing assets, ensuring that newly admitted patients can obtain well-fitting hospital gowns, improving patient comfort and medical experience; at the same time, it transforms the traditional manual distribution of hospital gowns into an automated self-service distribution model, thereby effectively improving the efficiency of patient admission procedures.

[0026] S300. If the patient is not a first-time visitor, a replacement process is executed, which includes: obtaining the patient's old hospital gown to be recycled, identifying the unique identifier on the old hospital gown and verifying its legality; after the verification is successful, removing the association between the unique identifier and the patient's identity information, and distributing hospital gowns according to the patient's current size requirements; if the verification fails, triggering an exception handling mechanism and marking the old hospital gown.

[0027] Specifically, non-first-time patient visits mainly occur during routine changing of clothes during hospitalization or upon discharge. In this case, the system first receives the old hospital gown from the patient and uses a built-in identification element to read the unique identifier sewn or pasted on the clothing, such as a UHF RFID tag or a dedicated QR code. After the identification element reads the unique identifier on the old hospital gown, the system uses this identifier as an index to look up the currently bound patient ID in the database. Subsequently, the system performs a field-by-field binary comparison between the retrieved patient ID and the current patient's identity information obtained in step S100. Only when the two match completely is the verification considered successful, proving that the clothing is indeed used by the current patient and is in legal possession. Otherwise, the verification fails.

[0028] If the verification passes, the system immediately disconnects the garment's identifier from the original patient's identity in the database, turning it into a free asset awaiting cleaning. Simultaneously, new garments are distributed based on the patient's current needs. If the verification fails—for example, if the identified identifier does not belong to the current patient or is damaged and unreadable—the system will automatically trigger an exception handling mechanism. This may include displaying a pop-up notification on the interface, issuing a voice warning, or marking the garment as "of unknown origin" in the background and locking the corresponding recycling slot. This prevents incorrect garments from being mixed in, effectively eliminating the risk of lost, misappropriated, or cross-used garments.

[0029] It should be noted that the specific details of the patient's size-based medical attire include: The control unit provides the patient with size change options. For example, the control unit displays a size confirmation interface to the patient through a human-computer interaction input module, which includes at least two function buttons or touch areas: "Keep original size" and "Remeasure".

[0030] In response to a patient's request to change size, the system re-collects the patient's body parameters and determines a new target size based on these parameters. Hospital gowns are then distributed according to the determined target size. For example, when a patient clicks or touches the "Remeasure" option on the interface, the system determines that this is a response to a size change request and automatically activates the height, weight, and circumference measurement modules in the data acquisition unit to collect the patient's current height, weight, chest circumference, waist circumference, and other key body parameters in real time. After collection, the control unit uses a built-in size matching algorithm or mapping table to calculate a new target size suitable for the current body type based on this latest data. For example, if a patient's waist circumference increases due to postoperative edema, the system will automatically match a larger waist size hospital gown by re-collecting data, thus avoiding discomfort caused by distributing gowns based solely on experience or old data.

[0031] In response to the patient's choice not to change their size, the system retrieves the patient's historical size record, determines the target size based on this record, and distributes the garment according to the determined target size. For example, when the patient selects the "Keep Original Size" option on the interface, the system determines that this is a response to the patient's choice not to change their size. In this case, the system does not trigger sensor data collection; instead, it directly accesses the backend database or local cache through the communication interface to retrieve the historical size record associated with the patient's identity information. The historical size record can be the target size determined during the last successful distribution or the mode size that appears most frequently in multiple distribution records. The system directly uses the historical record as the target size for this distribution and generates the distribution instruction accordingly. Therefore, in normal scenarios where the patient's body shape does not change significantly, this eliminates tedious measurement waiting time and significantly improves equipment turnover efficiency and patient experience during peak changing periods.

[0032] Example 2 like Figures 2-8 As shown, this embodiment provides a patient gown receiving and dispensing management system, including at least one control cabinet 10 and at least one storage cabinet 20. Figure 2 The diagram shows a control cabinet 10 equipped with two storage cabinets 20, which can store shirts and pants respectively, so as to realize the retrieval and storage of items in separate areas.

[0033] The control cabinet 10 is equipped with a control unit, an identification unit, and a data acquisition unit. The identification unit is used to acquire the patient's identity information and determine the patient's medical treatment type based on the identity information, for example, by using a binocular liveness detection camera integrated on the top of the cabinet or an embedded RFID reader. The data acquisition unit is used to collect the patient's body parameters, such as height, weight, and three-dimensional dimensions. The control unit is used to execute the logic control of the initial distribution process and the replacement process. It is usually implemented by an industrial computer or PLC controller built into the cabinet and communicates with various sensors and drive components through an internal bus.

[0034] Specifically, the data acquisition unit includes one or more of the following: a height measurement module 11, a weight measurement module 12, a dimensional measurement module 13, and a human-computer interaction input module 14. The height measurement module 11 is an ultrasonic rangefinder or infrared rangefinder mounted on the control cabinet 10; the weight measurement module 12 is an electronic scale mounted on the bottom or front of the control cabinet 10; the dimensional measurement module 13 is an electronic measuring tape mounted on the control cabinet 10; and the human-computer interaction input module 14 is a touch screen display for manually inputting body parameters. It should be understood that although this embodiment lists the specific sensor types described above, in other embodiments, height measurement can also use a binocular stereo vision camera or LiDAR, weight measurement can use an embedded pressure sensor array, and dimensional measurement can use millimeter-wave radar scanning or photoplethysmography, as long as the body parameters used for size matching can be obtained.

[0035] Furthermore, in this embodiment, the control cabinet 10 is provided with a drive device 15 and a storage drawer 16 that is pulsatorically connected to the drive device 15. The dimension measurement module 13 (electronic flexible ruler) is housed in the storage drawer 16. The drive device 15, in response to the activation of the data acquisition unit, drives the storage drawer 16 to extend outward from the control cabinet 10. Figure 7 and Figure 8As shown, the drive unit 15 typically consists of a stepper motor or servo motor in conjunction with a lead screw module, hidden within the internal cavity of the control cabinet 10. When the patient triggers a dimensional measurement command on the human-machine interface input module 14, or when the system determines that circumference acquisition is required, the control unit sends a pulse signal to the drive unit 15, driving the storage drawer 16 to smoothly slide out from inside the control cabinet 10 to a preset operating position, facilitating the user to retrieve the dimensional measurement module 13 from the storage drawer 16. It should be understood that, in addition to lead screw transmission, the drive unit 15 can also employ linear drive mechanisms such as electric push rods or linear motors.

[0036] Furthermore, a detection device 17 is installed inside the drawer 16. This detection device 17 detects the unique mark on the dimension measurement module 13. The drive device 15, responding to the detection result of the detection device 17, normally retracts the drawer 16 into the control cabinet 10. Specifically, the dimension measurement module 13 has a unique mark distinct from ordinary structures. This mark can be an RFID tag embedded in the module housing, a magnetic element at a specific location, or an optical identification code with unique reflectivity. The detection device 17 is installed on the bottom or side wall of the return slot inside the drawer 16. Only when the dimension measurement module 13 is correctly returned to its designated position can the detection device 17 read the unique mark and output a "normal return" signal. The control unit uses this signal as a condition for allowing the drawer to retract. If this signal is not detected, even if a closing command is received, the drive device 15 will not perform the retraction action, thereby completely avoiding mechanical damage and tool loss caused by the module not being returned to its proper position or being placed askew.

[0037] Building upon the above, this embodiment also introduces a timeout monitoring module. After the drawer 16 extends, the control unit immediately starts a preset countdown (e.g., any time between 2 and 5 minutes). If the detection device 17 fails to detect the unique marker of the dimension measurement module 13 before the countdown ends (i.e., the module has not been returned), the system will determine it as an abnormal state and immediately perform an abnormal marking operation on the current patient. This abnormal marking can be recorded in the background database as a violation of the patient's usage rules, or it can be indicated via a pop-up window on the human-computer interaction input module 14, notifying medical staff to intervene and handle the situation, thereby effectively preventing the measurement module from being accidentally lost in an unattended environment.

[0038] The storage cabinet 20 is equipped with a conveying unit and a recycling unit. The conveying unit includes a conveyor belt 21 and a drive wheel assembly 22 that is driven and connected to the conveyor belt 21; for example Figure 3 and Figure 4As shown, the conveyor belt 21 is typically a flexible closed-loop belt structure, surrounding and arranged between drive wheel sets 22 arranged vertically or horizontally. The drive wheel sets 22 are driven by a motor to rotate, thereby driving the conveyor belt 21 in a cyclical motion. Multiple separators 23 are spaced apart on the surface of the conveyor belt 21, forming storage slots between adjacent separators 23 for storing clean hospital gowns. The separators 23 can be rigid baffles or flexible curtains vertically fixed to the belt surface, preventing clothing from slipping or being squeezed during transport, and ensuring that each storage slot can only hold one set of hospital gowns.

[0039] Furthermore, an accommodating space is formed on the inner side of the conveyor belt 21; the inner side refers to the internal area surrounded by the closed loop of the conveyor belt 21, and the recycling unit is disposed within the accommodating space.

[0040] The recycling unit includes a fixed sleeve 24 and a movable part 25 that can slide relative to each other. The fixed sleeve 24 is fitted over the movable part 25. The movable part 25 has multiple recycling slots for storing old hospital gowns. The fixed sleeve 24 has multiple identification elements, each corresponding to a recycling slot, used to identify the unique identifier on the old hospital gown within that slot. Figure 4 In the example shown, the movable part 25 has a drawer-type structure, and the fixed sleeve 24 is a static shell structure that tightly wraps around the outside of the movable part 25, forming a sliding fit between the two; the identification element is embedded in the inner wall or top of the fixed sleeve 24 to ensure that the old hospital gown can be in the optimal reading area of ​​the identification element, thereby improving the identification success rate.

[0041] In one embodiment, the movable component 25 is slidably connected to the fixed sleeve 24 via an electric slide rail assembly 27; the electric slide rail assembly 27 includes a linearly driven electric guide rail and an electric slider. Specifically, as... Figure 4 and Figure 6 As shown, the electric guide rail of the electric slide rail assembly 27 is typically fixed horizontally on the inner wall or bottom base of the fixed sleeve 24, while the electric slider is rigidly connected to the outer wall or base plate of the movable part 25. When the control unit issues an extension or retraction command, the drive motor built into the electric guide rail starts, converting the rotational motion into the linear reciprocating motion of the electric slider through a transmission mechanism such as a lead screw, synchronous belt, or gear rack, thereby driving the movable part 25 to slide smoothly out or retract relative to the fixed sleeve 24. In addition, the electric slide rail assembly 27 can also integrate limit switches or encoders to provide real-time feedback to the control unit on the position status and operating current of the movable part 25. Once abnormal resistance or overtravel is detected, the system can immediately perform emergency stop or reverse protection to prevent motor overload or structural damage.

[0042] Furthermore, a partition 26 is provided between adjacent recycling tanks, and the partition 26 is equipped with a disinfection device for disinfecting the old hospital gowns stored in the recycling tanks; the disinfection device is one or more of an ultraviolet disinfection lamp, an ozone generator, a plasma disinfection device, or a heating disinfection device. Specifically, as... Figure 6 As shown, the interior of the movable component 25 is divided into several independent recycling tanks by multiple vertically or horizontally arranged partitions 26, each corresponding to a used patient gown. The partitions 26 not only serve as physical separators to prevent the mixing of clothing from different patients, but also effectively integrate the disinfection function into the internal structure of the recycling unit. The disinfection device is usually embedded or attached to the surface of the partition 26, so that its radiating surface or release port faces directly towards the interior space of the recycling tank. For example, when using ultraviolet disinfection lamps, an array of UVC band LED beads can be evenly distributed on both sides of the partition to use ultraviolet light to destroy the DNA / RNA structure of microorganisms and achieve surface sterilization. When using an ozone generator, ozone gas can be slowly released into the tank through the micropores on the partition, and its strong oxidizing properties can penetrate the fabric fibers to kill deep-seated bacteria. When using a plasma sterilizer, low-temperature plasma can be generated in the sealed tank to achieve efficient inactivation of drug-resistant bacteria. In scenarios requiring rapid turnover, heating disinfection devices such as PTC ceramic heating plates can also be selected to achieve instant sterilization through high-temperature heat. The above-mentioned disinfection methods can be used individually or in combination according to the hospital's actual infection control level requirements, thereby effectively preventing dirty clothes from becoming a secondary source of contamination while they are temporarily stored and awaiting cleaning.

[0043] In addition, the cabinet door of the storage cabinet 20 is provided with a retrieval port and a recycling port. The retrieval port is connected to one of the storage slots of the conveying unit, and the recycling port is located in relation to the movable part 25, so that the movable part 25 can extend at least partially out of the storage cabinet 20 through the recycling port.

[0044] Furthermore, a sealing element 28 is provided at one end of the fixed sleeve 24 near the cabinet door of the storage cabinet 20. The sealing element 28 is used to seal the gap between the fixed sleeve 24 and the cabinet door, so as to isolate the storage tank from the recycling tank. Specifically, the sealing element 28 can be a component made of flexible or elastic materials such as a high-density nylon brush, a silicone sealing strip, or a magnetic attraction sealing gasket. During the extension and retraction of the movable part 25, the sealing element 28 can adaptively fill the gap between the end face of the fixed sleeve 24 and the inner wall of the cabinet door caused by machining tolerances or assembly gaps, thereby effectively blocking the air convection path between the recycling channel (recycling tank) and the clean storage area (storage tank), and preventing aerosols, dust, or pathogenic microorganisms carried by soiled clothing from spreading to the clean patient gown storage tank. It should be understood that although the figure shows the form in which the sealing element 28 is set on the end face of the fixed sleeve, in other embodiments, the sealing element can also be set at the corresponding position on the inner side of the cabinet door.

[0045] Furthermore, the retrieval opening is equipped with an automatically opening and closing retrieval door 18. The retrieval door 18 is electrically connected to the control unit. The control unit responds to a patient's medical service command by controlling the retrieval door 18 to open and closes it after a preset delay time. Specifically, as... Figure 3 As shown, the retrieval door 18 is installed on the outside or inside of the retrieval opening on the front of the storage cabinet 20, and its form can be a sliding door. The retrieval door 18 is electrically connected to the control unit through a built-in micro DC motor, stepper motor, or electromagnetic actuator. The control unit directly sends pulse signals or level signals to drive it to perform opening or closing actions. When the control unit completes size matching and sends a dispensing instruction for the patient gown to the conveyor unit, this instruction also serves as an opening trigger signal for the retrieval door 18, causing the retrieval door 18 to open in advance or simultaneously with the conveyor belt 21 before the target patient gown is delivered to the corresponding position of the retrieval opening, thus reserving an unobstructed retrieval passage for the patient. In addition, the preset delay time refers to the time interval between the moment the retrieval door 18 is fully opened and the moment the control unit issues a closing instruction; this time parameter can be configured according to the actual usage scenario, for example, set to 10 seconds or 15 seconds.

[0046] In summary, let's take a hospitalized patient's self-service gown change as an example. We'll define the patient as someone recovering from surgery. This patient has previously received a hospital gown (i.e., not their first visit), but due to post-operative edema, their body shape has changed significantly, requiring a larger size gown. The entire self-service change process encompasses four stages: identity verification, dynamic size matching, old gown collection and verification, and automatic new gown distribution. The specific process is as follows: First, during the identity recognition stage, the patient stands in front of the control cabinet 10. The identity recognition unit collects the patient's facial features and obtains identity information through a binocular camera. Based on this identity information, the control unit queries the background database and finds that the patient has a historical clothing binding record, thereby automatically determining that the patient is not a first-time visitor.

[0047] Next, the used clothing recycling stage begins. The human-machine interface input module 14 prompts the patient to deposit their used hospital gown. The control unit drives the electric slide rail assembly 27 to extend the movable part 25 horizontally out of the storage cabinet 20 through the recycling port. The patient places the used hospital gown into the recycling slot of the movable part 25. Subsequently, the movable part 25 automatically retracts. During this process, the sealing element 28 at the end of the fixing sleeve 24 tightly adheres to the inner wall of the cabinet door, sealing the gap between the fixing sleeve 24 and the cabinet door, ensuring that the storage slot and recycling slot are isolated from each other, thereby blocking the exchange of contaminated airflow. Once the movable part 25 is fully retracted, the identification element inside the fixing sleeve 24 reads the RFID tag on the used hospital gown as a unique identifier and compares its associated identity information with the current patient information. If the comparison matches, the verification passes, and the system removes the tag from the original patient's information. Simultaneously, the ultraviolet disinfection lamp on the partition 26 immediately activates, instantly disinfecting the used hospital gown in the recycling slot to prevent the growth and spread of pathogens during temporary storage.

[0048] After the old clothes are collected, the touch screen of the human-computer interaction input module 14 jumps to the replacement process interface and provides the patient with size change options, including two touch buttons: "Keep the original size" and "Remeasure". Given the patient's own body shape changes, he clicks on the screen to select the "Remeasure" option. The system responds to the instruction to change the size and enters the dynamic parameter acquisition stage.

[0049] Next, during the dynamic parameter acquisition phase, the control unit sends a pulse signal to the drive device 15, causing the drawer 16 containing the dimension measurement module 13 to smoothly extend outward to the preset operating position outside the control cabinet 10. The patient uses the extended dimension measurement module 13, along with the height measurement module 11 and weight measurement module 12, to complete real-time acquisition of chest circumference, waist circumference, height, and weight. After measurement, the patient places the dimension measurement module 13 back into the designated slot in the drawer 16. At this time, the detection device 17 inside the drawer 16 detects the unique mark on the dimension measurement module 13. After confirming normal placement, the drive device 15 performs a retraction action, returning the drawer 16 back into the cabinet. If the patient does not return the dimension measurement module 13 within a preset countdown, the system will trigger an abnormality flag and prompt medical personnel to intervene to prevent asset loss. The latest acquired body parameters are transmitted to the control unit, and after algorithm matching, a new target size is determined (e.g., changing from size M to size L).

[0050] Finally, during the automatic garment distribution phase, the control unit generates and issues a command based on the newly determined target size L, driving the transmission wheel assembly 22 to rotate the conveyor belt 21, accurately transporting the corresponding clean hospital gown from the storage slot to the retrieval port. Simultaneously, the retrieval door 18 corresponding to the L size automatically opens and closes after a preset delay time. The patient retrieves the well-fitting new hospital gown from the retrieval port, completing the self-service garment change.
