Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a multifunctional intelligent medical cart. Background Art

[0002] At present, in the diagnosis and treatment activities of medical institutions, it is usually necessary to collect body fluid samples from patients for testing, such as blood, urine, saliva and other test samples, especially for the collection of test samples of hospitalized patients. Medical staff usually push medical carts to various wards. Existing medical carts usually only include simple storage layers or storage drawers. Even if there are functional partitions, the partitions cannot be flexibly adjusted. The functions are relatively simple and cannot adapt to a variety of working environments. Traditional medical carts do not have intelligent management functions. Medical staff need to manually record the information of each patient and finally organize and enter the information in a unified manner. The workload is quite large, which brings certain inconveniences to daily nursing work.

[0003] To complete the collection of test samples, medical institutions need to sort various sample containers, divide them into different batches and send them to the corresponding testing departments for testing. Currently, the information collection and sorting of sample containers are mostly done manually, and the workload of medical staff is quite large.

[0004] Nowadays, large medical institutions have to complete a large number of body fluid sample tests every day. With the emergence of new test indicators and new test technologies, the number of test items and samples of body fluid samples in medical institutions is increasing. With such a huge number of samples, information collection and sorting should be carried out according to relevant test items. Manual collection and sorting methods alone can no longer meet the needs of modern medical care. It is not only time-consuming and labor-intensive, but also has low efficiency and high error rate in manual information collection and sorting, which can easily cause conflicts between doctors and patients. On the other hand, the timeliness and timeliness of test samples also pose challenges to the information collection and sorting of existing sample containers. Now there are also some test tube sorting equipment, most of which have defects such as complex structure, high cost, low efficiency or low degree of automation, and narrow scope of application, which cannot fully meet the needs of modern medical development.

[0047] The multifunctional intelligent medical cart of the present invention is described in detail below in conjunction with the embodiments and drawings.

[0048] The multifunctional intelligent medical cart of the present invention is divided into two parts from the functional structure, the internal structure and the external structure. The design of the external structure is mainly based on the convenience and reliability of medical staff in medical institutions to collect test samples in wards. The design of the internal structure is mainly based on reducing the workload of operators, improving work efficiency, and increasing reliability. It is used to automatically scan and sort the sample containers after collection. The medical cart of the present invention integrates multiple functions into one, and adopts an intelligent control method to realize the orderly and reliable operation of the medical cart.

[0049] The multifunctional intelligent medical cart adopts a multi-compartment design on the external structure, and has a compact structure. Figure 1A and Figure 1C As shown, the multifunctional intelligent medical cart includes a shell 01, and a plurality of drawers 05 are arranged on the front side of the shell 01 for placing blood drawing tools (blood drawing needles, blood drawing tubes, etc.), commonly used medical consumables (such as cotton swabs, tourniquets, etc.), and a drawer indicator light 06 is arranged above each drawer 05 for indicating the drawer 05 corresponding to the pre-placed sample container, so as to facilitate medical staff to quickly locate. Preferably, the drawer 05 can accommodate fifteen sample containers of maximum size; a trash can 07 for holding medical waste (such as discarded cotton swabs, blood drawing needles and other consumable waste) is arranged on the lower part of the front side of the shell 01, and an inner liner for convenient retrieval is arranged in the trash can 07, and a trash bag can be put in the inner liner. The trash can 07 is opened and closed in the form of a pedal. When in use, the trash can 07 can be opened by stepping on the pedal, and the trash can is closed by releasing the pedal. A wheel 010 is provided at each of the four corners of the bottom of the shell 01. The wheel 010 is preferably a universal wheel that can be locked. A handle 011 is provided at the front side and the rear side of the upper part of the shell 01. The front handle adopts an extended design to prevent the user's feet from hitting the body of the cart during the pushing process, which is convenient for medical staff to push the medical cart. Furthermore, the edge of the handle 011 adopts an arc design to provide medical staff with grip comfort.

[0050] See also Figure 1DA storage platform 02 is provided on the top of the housing 01 for temporarily placing items. The storage platform 02 adopts a large-area flat design, and the raised frames around it can prevent the items placed on it from sliding down. The storage platform 02 is provided with a container placement port 013 (corresponding to the container collection tank 11 in the internal structure) for sorting sample containers. The container placement port 013 is provided with a sliding hatch. The hatch is opened when in use, and the sliding hatch closes the container placement port 013 when not in use to prevent debris from falling into the interior. An adjustable bracket 03 is provided on the storage platform 02. A display screen 04 is provided on the top of the adjustable bracket 03. The adjustable bracket 03 adopts an articulated support structure. The position of the display screen 04 can be adjusted in the horizontal and vertical directions by adjusting the angles between the joints. The display screen 04 is rotatably connected to the top of the adjustable bracket 03, and the azimuth angle of the display screen 04 can be freely adjusted within a range of 360 degrees, which is convenient for medical staff to flexibly adjust according to the on-site situation and easy to operate.

[0051] See also Figure 1B The rear front of the housing 01 is provided with a sorting bucket hatch 08. By opening the sorting bucket hatch 08, the sorting bucket 31 located at the sorting bucket hatch 08 can be easily taken out; further, in order to prevent accidental taking, the taking out of the sorting bucket 31 requires the allocation of corresponding authority. The housing 01 is provided with a card swiping area 012, and the card swiping area 012 is provided with a card reader. After the operator swipes the card, the sorting bucket hatch 08 is opened manually or automatically. Preferably, the card swiping area 012 is set on the storage table 02 to facilitate the operation of the operator. Furthermore, the rear side of the housing 01 is also provided with a power hatch 09, and the power hatch 09 is provided with a buckle for easy opening and closing. The power cord of the medical cart is stored in the power cabin, which is beautiful and neat, and avoids damage caused by dragging the wires during use.

[0052] Furthermore, the users of the smart medical cart are mostly women, and its design fully considers the principles of ergonomics, selecting the average height of women as the height of the smart medical cart.

[0053] A controller 40 is provided inside the housing 01 of the multifunctional intelligent medical cart of the present invention, and the display screen 04, the drawer indicator light 06, and the card reader of the card swiping area 012 are all electrically connected to the controller 40. The controller 40 includes a processor, a memory, and an information processing module. The memory pre-stores the information table of the patient information and the collection information of the pre-collected test samples and the number information of each drawer 05. The display screen 04 is a liquid crystal touch screen. The operator can perform various operations and parameter settings by touch, bind the corresponding patient information and the collection information with the number of the drawer 05, and form a mapping table stored in the memory; or the display screen 04 is equipped with a keyboard and / or a mouse, and the input or parameter setting operation can be performed by the keyboard and the mouse. The operator inputs the information table of the patient information and the collection information of the pre-collected test samples and the number information of each drawer 05 into the controller 40 and establishes a mapping relationship to generate a mapping table, which is stored in the memory. When in use, the operator clicks on the patient information, and the drawer indicator light 06 above the corresponding drawer 05 lights up. The operator can open the drawer 05, take out the corresponding sample container and / or the corresponding collection tool to collect the test sample, and put it into the corresponding drawer after the collection is completed. This design can prepare tools and containers for collecting test samples from corresponding patients in advance, avoid chaos in temporary processing on site, and improve work efficiency and reliability.

[0054] The internal structure design of the multifunctional intelligent medical cart of the present invention is mainly used for automatic information scanning and automatic sorting of sample containers after collection. The internal structure of the multifunctional intelligent medical cart is implemented as follows: Figure 2 As shown, it includes a fixed support frame 50 and an automatic pushing mechanism 10, an automatic scanning mechanism 20 and an automatic sorting mechanism 30 which are installed on the fixed support frame 50 and are connected in sequence from top to bottom. The controller 40 is arranged on the fixed support frame 50 and is used to control the above mechanisms to work in order according to a predetermined program, wherein:

[0055] The automatic pushing mechanism 10 is used to collect and push the sample containers to the automatic scanning mechanism 20 in sequence, in preparation for subsequent automatic sorting. Figure 3A As shown, it includes a container collecting tank 11, a lifting and pushing mechanism 12, a lifting drive mechanism 13 and a container channel 14. The lifting and pushing mechanism 12 is located between the container collecting tank 11 and the container channel 14, and the lifting drive mechanism 13 is located below the lifting and pushing mechanism 12, and is used to drive the pushing plate in the lifting and pushing mechanism 12 to move vertically.

[0056] Specifically, the structure of the lifting and pushing mechanism 12 is as shown in Figure 3B, including a vertically arranged track frame 123 and a first pushing plate 121 and a second pushing plate 122 vertically installed in parallel on the track frame 123. The track frame 123 is a U-shaped frame, and two rows of tracks are correspondingly opened on the U-shaped side walls 1231 on both sides. The two side edges of the first pushing plate 121 match the first track 1233 close to the U-shaped bottom 1232 of the track frame 123, and the two side edges of the second pushing plate 122 match the second track 1234 away from the U-shaped bottom 1232 of the track frame 123. The first pushing plate 121 and the second pushing plate 122 can move up and down along the track frame 123.

[0057] The container channel 14 is a rectangular cavity structure with two ends open, and its channel entrance 141 faces the container collection tank 11 and is fixed to the upper end of the track frame 123. The upper end of the U-shaped bottom 1232 of the track frame 123 is provided with a notch, and the channel entrance 141 of the container channel 14 is placed at the notch, and the lower side of the channel entrance 141 is close to the upper edge of the U-shaped bottom 1232 of the track frame 123. Both sides of the channel entrance 141 are fixed to the U-shaped side walls 1231 on both sides of the track frame 123. The channel outlet 142 of the container channel 14 faces the V-shaped groove structure 21 of the automatic scanning mechanism 20, so that the sample container enters the automatic scanning mechanism 20 from the container channel 14 under the action of the lifting and pushing mechanism 13 for scanning. The container channel 14 is placed at an angle with the track frame 123, and the angle is preferably 35o-45o. The upper side edge and the lower side edge of the channel entrance 141 are vertically aligned, so that the sample container does not go out of the container channel 14. Preferably, a through-beam photoelectric sensor 143 is further provided near the channel entrance 141 of the container channel 14. The transmitter and receiver of the through-beam photoelectric sensor 143 are symmetrically installed on the side walls of the container channel 14 on both sides. When a sample container is pushed into the container channel 14, it blocks the light path emitted by the transmitter when passing between the transmitter and the receiver of the through-beam photoelectric sensor 143. The receiver outputs a switch control signal, which is sent to the controller 40. The controller 40 can determine that a sample container has entered the automatic scanning mechanism 20 based on the switch control signal.

[0058] like Figure 3AAs shown, the lifting drive mechanism 13 is used to drive the first push plate 121 and the second push plate 122 to move up and down alternately, and includes a connecting rod mechanism 131 and a first motor 132. The connecting rod mechanism 131 includes a crank shaft 1311, a first connecting rod 1312 and a second connecting rod 1313, wherein the two ends of the first connecting rod 1312 are respectively hinged to the first push plate 121 and the crank shaft 1311, and the two ends of the second connecting rod 1313 are respectively hinged to the second push plate 122 and the crank shaft 1311, one end of the crank shaft 1311 is connected to the output shaft of the first motor 132, and the other end is rotatably mounted on the fixed support frame 50. The first motor 132 drives the crank shaft 1311 to rotate, thereby realizing the first push plate 121 and the second push plate 122 to move up and down alternately.

[0059] For details, see Figure 3A , Figure 3C and Figure 3D The container collecting groove 11 is an inclined groove structure, which is used to collect and place the sample containers to be scanned, including a trapezoidal bottom surface 111 and a groove wall 112. The opening side of the container collecting groove 11 faces the track frame 123 and the groove wall 112 on the opening side is fixed on the U-shaped side wall 1231 of the track frame 123. The wider side of the trapezoidal bottom surface 111 is close to the track frame 123, and the closer the container collecting groove 11 is to the track frame 123, the deeper the groove depth is. The angle between the trapezoidal bottom surface 111 and the horizontal plane is preferably 40o-60o, and the angle between the two side groove walls of the container collecting groove 11 and the first pushing plate 121 and the second pushing plate 122 is preferably 70o-80o. This structural design ensures that the sample containers poured into the container collecting groove 11 will not stick to the two side groove walls 112, and will slide to the lowest point located at the track frame 123, ensuring that the sample containers can enter the automatic scanning mechanism 20 through the lifting and pushing mechanism 12.

[0060] In order to prevent the sample container from rolling off the top of the first pushing plate 121 or the second pushing plate 122 during the pushing process of the lifting and pushing mechanism 12, the top of the first pushing plate 121 and the second pushing plate 122 are inclined surfaces (top surfaces), which are inclined toward the side of the container channel 14, and the angle between the top surface and the horizontal plane is 5o-30o, preferably 20o-30o; the width of the first pushing plate 121 and the second pushing plate 122 is preferably between 1 and 2 times the diameter of the sample container, ensuring that only one sample container is pushed each time.

[0061] In one embodiment, the height of the first pushing plate 121 is greater than the height of the second pushing plate 122, so that the two pushing plates form a stepped relay pushing scheme, that is, the second pushing plate 122 is responsible for sending the sample container located in the container collecting tank 11 to the top of the first pushing plate 121, and the second pushing plate 121 is responsible for pushing the sample container into the container channel 14 and then into the automatic scanning mechanism 20.

[0062] In the automatic pushing mechanism 10, the first motor 132 is electrically connected to the controller 40. The controller 40 controls the first motor 132 to drive the first pushing plate 121 and the second pushing plate 122 to move up and down alternately. Figure 3C and Figure 3D The process shown includes the following:

[0063] When the second pushing plate 122 is located at the lower limit position, the top of the second pushing plate 122 is flush with the trapezoidal bottom surface 111 of the container collecting tank 11, and the sample container automatically moves to the top of the second pushing plate 122;

[0064] The first motor 132 drives the second pushing plate 122 to rise, and the first pushing plate 121 to fall. When the top of the first pushing plate 121 is flush with the top of the second pushing plate 122 (the first pushing plate 121 is at the lower limit position, and the second pushing plate 122 is at the upper limit position), a sample container located at the top of the second pushing plate 122 slides to the top of the second pushing plate 121.

[0065] The first motor 132 drives the first pushing plate 121 to rise and the second pushing plate 122 to descend until the top of the first pushing plate 121 is flush with the lower side of the channel entrance 141 of the container channel 14. Since the top of the first pushing plate 121 is inclined toward the channel entrance 141, the sample container automatically moves into the channel entrance 141 and enters the automatic scanning mechanism 20 along the container channel 14. At this time, the second pushing plate 122 is located at the lower limit position. The above process can be repeated to continuously push the sample container.

[0066] The automatic pushing mechanism 10 of the present invention is fixed on the fixed support frame 50. The design of the automatic pushing mechanism 10 fully considers the problems existing in the sample container pushing process. For example, when multiple sample containers are poured into the container collecting tank 11, in order to ensure that the sample containers (usually test tubes of different specifications) are automatically transferred to the top of the second pushing plate 122 at the lowest point of the container collecting tank 11, the bottom of the container collecting tank 11 is designed to be inclined toward the track frame 123, so that the sample container rolls toward the top of the second pushing plate 122 under the action of potential energy; in order to prevent the sample container from getting close to the tank wall of the container collecting tank 11 and failing to enter the top of the second pushing plate 122, the bottom of the container collecting tank 11 is designed to be inclined toward the track frame 123. The surface is designed as a trapezoidal bottom surface, and the end close to the track frame 123 is wider. In this way, due to the effect of gravity, the sample container cannot be stably attached to the groove wall. During the up and down movement of the first pushing plate 121 and the second pushing plate 122, the sample container tends to roll to the top of the second pushing plate 122 in a manner parallel to the second pushing plate 122; to prevent the sample container from slipping during the pushing process, the top of the first pushing plate 121 and the second pushing plate 122 is set to be an inclined surface inclined toward the track frame 123 to ensure stable pushing; to prevent two sample containers from being pushed at one time, the width of the first pushing plate 121 and the second pushing plate 122 is not more than twice the diameter of the sample container.

[0067] Furthermore, in order to improve the pushing efficiency of the sample container, the automatic pushing mechanism 10 can be provided with multiple pushing plates to form a multi-level stepped relay pushing scheme, and the corresponding lifting drive mechanism 13 is also provided with multiple connecting rods, each connecting rod connecting the corresponding pushing plates. When the upper pushing plate is at the lower limit position, the adjacent lower pushing plate is at the upper limit position, and the tops of the two pushing plates are flush, then the sample container on the top of the lower pushing plate moves to the top of the upper pushing plate, thereby realizing the sample container being transferred between the stepped pushing plates, and the sample container is transferred to the channel entrance 141 of the container channel 14 by relay, and enters the automatic scanning mechanism 20 through the container channel 14.

[0068] The automatic scanning mechanism 20 is located below the channel outlet 142 of the container channel 14, and is used to receive and scan the sample container pushed by the automatic pushing mechanism 10, so as to prepare for the subsequent automatic sorting operation. Figure 4A and Figure 4B The automatic scanning mechanism 20 includes a V-shaped groove structure 21, a scanner 22 located above the V-shaped groove structure 21, and a sorting channel 25 located below the V-shaped groove structure 21, wherein:

[0069] The V-shaped groove structure 21 includes a V-shaped groove that is wide at the top and narrow at the bottom, formed by a fixed inclined plate 211, a movable baffle 212 and a roller 213. The roller 213 is located at the bottom of the V-shaped groove, and the sample container is placed at the bottom of the V-shaped groove. An adjustable gap is provided between the movable baffle 212 and the roller 213. The sample container entering the V-shaped groove contacts the fixed inclined plate 211, the movable baffle 212 and the roller 213 at the same time.

[0070] The V-groove structure 21 also includes a second motor 23 and a third motor 24. One end of the roller 213 is connected to the output shaft of the first motor 23. The second motor 23 can drive the roller 213 to rotate, and at the same time drive the sample container contacting the roller 213 to rotate, so as to facilitate the scanner 22 to scan the scanning code of the sample container. Preferably, the surface of the roller 213 is roughened, for example, the surface of the roller 213 is engraved with stripes or patterns, or is ground to increase friction to ensure that the sample container can be driven to rotate; the movable baffle 212 is fixed on the output shaft of the third motor 24, and can rotate with the rotation of the third motor 24, thereby adjusting the size of the gap between the movable baffle 212 and the roller 213.

[0071] Preferably, the lower end of the fixed inclined plate 211 is located obliquely above the roller 213 and does not contact it, the lower end of the movable baffle 212 is located obliquely below the roller 213 and does not contact it, the gap between the fixed inclined plate 211 and the roller 213 is smaller than the diameter of the sample container, so as to prevent the sample container from falling from the gap and ensure that the sample container is always located on one side of the movable baffle 212; in one embodiment, the movable baffle 212 is provided with two positions that can be kept stable, namely the first position and the second position, the third motor 24 can drive the movable baffle 212 to rotate and maintain in the first position or the second position, the gap between the movable baffle 212 and the roller 213 at the first position is smaller than the diameter of the sample container, and the gap between the movable baffle 212 and the roller 213 at the second position is larger than the diameter of the sample container. The third motor 24 can drive the movable baffle 212 to switch between the first position and the second position, so as to keep the sample container at the bottom of the V-shaped groove, or allow the sample container to enter the sorting barrel of the automatic sorting device through the sorting channel 25.

[0072] The sorting channel 25 is a conveying channel for sample containers, the entrance of which faces the gap between the movable baffle 212 and the roller 213, and the exit of the sorting channel 25 is aligned with the position of the sorting barrel 31 of the automatic sorting mechanism 30. When the movable baffle 212 rotates under the drive of the third motor 24, the gap between the movable baffle 212 and the roller 213 is larger than the diameter of the sample container, and the sample container enters the sorting channel 25 from the gap formed by the movable baffle 212 and the roller 213. The sorting channel 25 can be directly connected to the V-groove structure 21, or it can be not in contact with the V-groove structure 21, as long as the exit of the sorting channel 25 faces the gap between the movable baffle 212 and the roller 213.

[0073] The scanner 22 is a mature product on the market and can be purchased from outside. The scanner 22 is installed on the fixed support frame 50 above the V-groove structure 21, and is used to scan the scanning code of the sample container falling into the V-groove, thereby obtaining the scanning information of the scanning code (including the patient's identity information and the test sample collection information), and transmits the collected scanning information to the controller 40. The controller 40 controls the automatic sorting mechanism 30 to transfer the sorting bucket with the corresponding number to the exit of the sorting channel 25 according to the acquired scanning information; then controls the third motor 24 to drive the movable baffle 212 to open, so that the sample container falls from the sorting channel 25 into the corresponding sorting bucket; then controls the first motor 132 to drive the lifting and pushing mechanism 12 to push the next sample container.

[0074] Preferably, the scanning head of the scanner 22 faces the bottom of the V-shaped groove, and the selected scanning area of ​​the scanner 22 can cover the bottom area of ​​the V-shaped groove, ensuring that the scanner 22 can scan the scanning code of the sample container.

[0075] The automatic scanning mechanism 20 is fixed on the fixed support frame 50. Under the control of the controller 40, the automatic scanning mechanism 20 cooperates with the automatic pushing mechanism 10 to sequentially transfer the sample containers to the designated sorting buckets in the automatic sorting mechanism 30. The controller 40 is provided with a network interface, through which the controller 40 is externally connected to a management information system and transmits the acquired scanning information to the management information system.

[0076] Figure 5A 01 is a structural example of the automatic sorting mechanism 30 of the present invention. A sorting barrel compartment is provided in the housing 01. The automatic sorting mechanism 30 is located in the sorting barrel compartment and includes a tray 32, a plurality of sorting barrels 31 arranged on the tray 32, a tray driving mechanism 33 for driving the tray 32 to rotate, and a sensor mechanism 34 for positioning the sorting barrels 31. The automatic scanning mechanism 20, the tray driving mechanism 33, and the sensor mechanism 34 are all electrically connected to the controller 40, wherein:

[0077] See also Figure 5B As shown, the tray 32 is a cylindrical structure, and an axial hole 322 is provided in the middle of the tray 32 for connecting the output shaft of the tray driving mechanism 33. A plurality of accommodating grooves 321 are evenly arranged in the circumferential direction inside the tray 32 for placing the sorting bucket 31. A through hole is provided at the bottom of the accommodating groove 321. On the one hand, the weight of the tray 32 can be reduced to facilitate driving the tray 32 to rotate. On the other hand, the through hole at the bottom of the accommodating groove 321 can be used in conjunction with the sensing mechanism 34 to detect whether the sorting bucket 31 is placed in the accommodating groove 321; a position mark 323 is provided at the bottom of the tray 32, which is used in conjunction with the sensing mechanism 34 to locate the reference position of the sorting bucket 31 (the reference position of the sorting bucket 31 refers to the sorting bucket 31 corresponding to the position mark 23 of the tray 32. Usually, the identification numbers of other sorting buckets 31 on the tray 32 are based on the reference position mark, and the rotation control strategy of the tray 32 is also designed based on the reference position).

[0078] See the structure of the sorting bucket 31 for details. Figure 5C , including a fan-shaped barrel body 311 and a handle 312 installed at the arc-shaped end of the fan-shaped barrel body 311. The shape of the fan-shaped barrel body 311 matches the receiving groove 321 of the tray 32. The sorting barrel 31 is placed in any receiving groove 321, and the handle 312 of the sorting barrel 31 is exposed to the outside, which is convenient for taking out the sorting barrel 31.

[0079] See also Figure 5AThe sensing mechanism 34 includes a photoelectric sensor 341 and a photoelectric switch 342, wherein the photoelectric sensor 341 is used to detect whether a sorting bucket 31 is placed in the receiving slot 321 of the tray 32. A diffuse reflection photoelectric sensor can be used, which is a photoelectric sensor composed of a transmitter and a receiver, installed below the bottom of the tray 32, and when the receiving slot 321 rotates to just above the photoelectric sensor 341, the photoelectric sensor 341 can align with the through hole at the bottom of each receiving slot 321. When the sorting bucket 31 is placed, when the light beam emitted by the transmitter of the photoelectric sensor 341 irradiates the bottom of the sorting bucket 31 placed in the receiving slot 321, sufficient light returns to the receiver of the photoelectric sensor 341, and the state of the photoelectric sensor 341 changes, and a state change signal is output.

[0080] The photoelectric switch 342 is provided with at least one, which is arranged below the bottom of the tray 32 and used in conjunction with the position mark 323 arranged at the bottom of the tray 32. In one embodiment, the photoelectric switch 342 is a slot-type photoelectric switch, including a U-shaped slot structure and a transmitter and a receiver respectively located on both sides of the U-shaped slot, the transmitter and the receiver are located on the same straight line and are arranged opposite to each other, and an optical axis is formed in the slot between the two. At this time, the position mark 323 is an opaque sheet component, such as an iron sheet, an opaque plastic, etc. When the opaque position mark 323 passes through the U-shaped slot to block the optical axis, the photoelectric switch 342 generates a switch signal.

[0081] In one embodiment, the tray driving mechanism 33 is a reduction stepper motor, the output shaft of the stepper motor is threadedly connected to the middle shaft hole 22 of the tray 32, and the stepper motor can rotate forward and reverse to drive the tray 32 to drive the sorting bucket 31 to rotate forward and reverse.

[0082] The automatic scanning mechanism 20 is used to scan the barcode or RFID information on the sample container to obtain scanning information, namely the patient's identity information (including name, gender, age, social security information, etc.) and test sample collection information (including collection type, collection time, test type, etc.). In one embodiment, the sorting outlet position of the automatic sorting mechanism 30 is fixed, and the outlet position corresponds to the position of the sorting bucket hatch 08 of the shell 01, which is called the standard position of the automatic sorting mechanism 30. The photoelectric sensor 341 and the photoelectric switch 342 of the sensing mechanism 34 are both fixed at the standard position of the automatic sorting mechanism 30. When the photoelectric switch 342 cooperates with the position identification 323 of the tray 32 to work, the reference position of the sorting bucket 31 on the tray 32 can be positioned at the standard position of the automatic sorting mechanism 30. At this time, the reference position of the sorting bucket 31 coincides with the standard position of the automatic sorting mechanism 30, and the identification numbers of other sorting buckets 31 are numbered based on the sorting bucket at the reference position. The identification number of the sorting bucket 31 is usually dynamically allocated for different sorting cycles, and the controller 40 binds the corresponding identification number to the scanning information obtained by scanning. When the operator wants to take out the corresponding sorting bucket 31, the controller 40 needs to obtain the identification number of the corresponding sorting bucket 31, and control the tray driving mechanism 33 to drive the tray 32 to rotate, so as to rotate the corresponding sorting bucket 31 to the standard position of the automatic sorting mechanism 30. The operator can then take out the sorting bucket 31 from the standard position of the automatic sorting mechanism 30.

[0083] Figure 5AIn the illustrated embodiment, the position marker 323 is mounted on the radial center axis of the bottom of the receiving groove 321 of the tray 32, and two photoelectric switches 342 are provided, namely, photoelectric switch 1 and photoelectric switch 2, which are symmetrically arranged on both sides of the axial hole 322 of the tray 32, that is, photoelectric switch 1 is installed at the standard position of the automatic sorting mechanism 30, and photoelectric switch 2 is installed at the position farthest from the standard position of the automatic sorting mechanism 30 in circumferential rotation (the farthest in both counterclockwise rotation and clockwise rotation). The two photoelectric switches are provided to help adjust the position deviation between the sorting bucket 31 and the standard position of the automatic sorting mechanism 30, so that the positioning of the sorting bucket 31 is more accurate. When the position mark 323 passes through the U-shaped groove of the photoelectric switch 1, the optical axis of the photoelectric switch 1 is blocked and a switch signal is generated, thereby determining the reference identification position of the sorting bucket 31; when the tray 32 rotates, the position mark 323 passes through the U-shaped groove of the photoelectric switch 2, the optical axis of the photoelectric switch 2 is blocked and a switch signal is generated, so that the rotation deviation of the receiving slot 321 of the tray 32 can be corrected in time, and the position deviation generated by simply controlling the position of the sorting bucket 31 by the rotation angle can be corrected, so that the sorting bucket 31 is facing the outlet of the sorting channel 25 in the automatic scanning mechanism 20. Obviously, the number of photoelectric switches 342 is not limited to one or two. In extreme cases, photoelectric switches 342 are set in sequence from the standard position of the automatic sorting mechanism 30, and each receiving slot 321 of the tray 32 corresponds to a photoelectric switch 342, so that the sorting bucket 31 is more accurately positioned.

[0084] In order to facilitate the operator to send the identification number of the pre-taken sorting bucket 31 to the controller 40, the controller 40 also includes a touch display screen with a human-computer interaction interface. The operator clicks on the key item in the scanning information bound to the identification number of the sorting bucket 31 through the human-computer interaction interface (usually the sorting type is a combination of one or more keywords in the scanning information, which is pre-defined), and the identification number of the corresponding sorting bucket 31 can be transmitted to the controller 40.

[0085] The plurality of sorting buckets 31 are respectively placed in the receiving grooves 321 of the tray 32. When the tray driving mechanism 33 drives the tray 32 to rotate, the groove wall of the receiving groove 321 cooperates with the lower part of the sorting bucket 31 to prevent the sorting bucket 31 from falling out under the centrifugal force generated during the rotation. The handle 312 of the sorting bucket 31 faces outwards to facilitate taking out the sorting bucket 31.

[0086] The exit of the sorting channel 25 in the automatic scanning mechanism 02 is aligned with the standard position of the automatic sorting mechanism 30 (i.e., the exit position of the sorting channel 25 in the automatic scanning mechanism 20). After the scanning of the sample container is completed, the controller 40 obtains the corresponding scanning information, and obtains the judgment result of which corresponding sorting bucket 31 on the tray 32 the sample container should be placed in, and generates a control instruction based on the judgment result, which is transmitted to the tray driving mechanism 33 to control the tray 32 to rotate the corresponding sorting bucket 31 to the reference position, and determines whether the sorting bucket 31 at this position exists by obtaining the status information of the photoelectric sensor 341. If it exists, the movable baffle 212 in the automatic scanning mechanism 20 is controlled to open, so that the sample container automatically falls from the sorting channel 25 into the sorting bucket 31 at the reference position, thereby realizing automatic sorting of the sample container.

[0087] The above embodiment is only a typical implementation of the present invention, and does not limit the shape and size of the tray 32 and the sorting bucket 31. Obviously, the accommodating groove 321 on the tray 32 matches the shape of the sorting bucket 31; the photoelectric switch 342 used to locate the reference position of the sorting bucket 31 and the position mark 323 used therewith can be replaced by a split-type photoelectric switch, whose transmitter and receiver are respectively arranged at the bottom of the tray 32 and the standard position of the automatic sorting mechanism 30 (or vice versa). At this time, the position mark 323 of the tray 32 is the transmitter or receiver of the photoelectric switch 342.

[0088] See also Figure 2 The fixed support frame 50 is a multi-layer frame structure, and the automatic pushing mechanism 10, automatic scanning mechanism 20, automatic sorting mechanism 30 and controller 40 are respectively fixed on each layer of the fixed support frame 50. Preferably, universal wheels are provided at the bottom of the fixed support frame 50 to form a compact movable trolley structure.

[0089] The multifunctional intelligent medical cart of the present invention controls the automatic pushing mechanism 10, the automatic scanning mechanism 20 and the automatic sorting mechanism 30 which cooperate with each other through the controller 40 to automatically separate the concentrated stacked sample containers, push them in sequence, automatically scan them and automatically sort them. The sorting efficiency is high, the sorting accuracy is good, the operation is convenient, and the needs of the development of modern medicine are met.

[0090] Automatic information collection and sorting of sample containers based on the automatic pushing mechanism 10, the automatic scanning mechanism 20 and the automatic sorting mechanism 30 include the following steps:

[0091] Step 1: The controller 40 controls the tray driving mechanism 33 to drive the tray 32 to rotate, so that the reference position of the sorting bucket 31 coincides with the standard position of the automatic sorting mechanism 30, and obtains a mapping table of the identification numbers and binding information items of all sorting buckets 31 on the tray 32 relative to the reference position in the current sorting cycle, wherein at least one sorting bucket is set as a secondary sorting bucket, and its corresponding binding information item is replaced by a specific identifier.

[0092] Among them, the standard position of the automatic sorting mechanism 30 is a fixed position, which is defined as the position corresponding to the sorting outlet of the automatic sorting mechanism 30 (i.e., the position corresponding to the outlet of the sorting channel 25 of the automatic scanning mechanism 20), and the reference position of the sorting bucket 31 is defined as the position of the storage slot corresponding to the position mark 323 of the tray 32. The identification number of the sorting bucket corresponding to the reference position is the reference identification number, and the identification numbers of other sorting buckets are numbered based on the reference identification number of the sorting bucket at the reference position. Since the storage slots 321 of each tray 32 are evenly arranged and the corresponding rotation angle of each sorting bucket 31 is the same, the controller 40 can identify the reference position of the sorting bucket 31 by obtaining the switch signal of the photoelectric switch 342, and number each sorting bucket 31 in turn by rotating the angle clockwise or counterclockwise relative to the reference position.

[0093] The mapping table between the identification number of the sorting bucket and the binding information item can be preset and stored in the memory of the controller 40, or can be set through the display screen of the controller 40.

[0094] The binding information item in the scanning information of the sample container does not exist in the mapping table between the identification number and the binding information item. At this time, the sample container is allocated to the secondary sorting bucket.

[0095] In step 2, the controller 40 controls the first motor 132 to drive the lifting and pushing mechanism 12 to move up and down. Once the switch control signal sent by the through-beam photoelectric sensor 143 is received, the controller 40 immediately stops the operation of the first motor 132, and controls the second motor 23 to drive the roller 213 of the automatic scanning mechanism 20 to rotate. The controller 40 receives the scanning information of the sample container obtained by the scanner 22, and executes step 3. If the controller 40 does not receive the switch control signal sent by the through-beam photoelectric sensor 143 within a predetermined time, it indicates that all the sample containers have been sorted, and then executes step 5.

[0096] Among them, the scanning information includes the patient's identity information, including name, gender, age, social security information, etc., as well as the test sample collection information, including collection type, collection time, test type, etc.

[0097] The predetermined time can be set as a multiple of the time period of the up and down movement of the lifting and pushing mechanism 12, preferably 3-6 times.

[0098] In step three, the controller 40 reads the mapping table between the identification number of the sorting bucket 31 and the binding information item, and extracts the identification number of the sorting bucket corresponding to the scanning information of the current sample container; if there is no identification number corresponding to the binding information item of the corresponding sorting bucket 31, the identification number of the secondary sorting bucket is extracted to arrange the current sample container to the next sorting cycle for sorting.

[0099] In step 4, the controller 40 controls the tray drive mechanism 33 to drive the tray 32 to rotate according to the shortest path control strategy, so that the sorting bucket 31 with the identification number corresponding to the current sample container rotates to the standard position of the automatic sorting mechanism 30, and controls the third motor 24 of the automatic scanning mechanism 20 to open the movable baffle 212, so that the sample container falls into the sorting bucket 31 with the corresponding identification number, and returns to step 2.

[0100] Specifically, taking eight sorting buckets 31 evenly arranged on the tray 32 as an example, the shortest path control strategy is described, that is, the rotation angle of the tray 32 is controlled by using a table lookup method. The control table of the eight sorting buckets 31 is shown in Table 1.

[0101] Table 1 Shortest path control strategy control table

[0102]

[0103] As shown in Table 1, for example, when the identification number of the sorting bucket 31 located at the standard position of the automatic sorting mechanism 30 is "1", if the identification number of the target sorting bucket 31 is "4", it is only necessary to query the 3rd row and 6th column in Table 1 to obtain that the rotation angle of the tray 32 is 135° counterclockwise; if the identification number of the target sorting bucket 31 is "5", it is only necessary to query the 3rd row and 7th row in Table 1 to obtain that the rotation angle of the tray is 180° counterclockwise. At this time, the purpose can also be achieved by rotating the tray 180° clockwise, and the rotation path is the same. This embodiment specifies that the preferred rotation direction is counterclockwise (the preferred rotation direction can also be specified as clockwise).

[0104] Step five, select the identification number of the corresponding sorting bucket 31 or the binding information item corresponding to the identification number through the display screen of the controller 40, and the controller 40 controls the rotation of the tray 32 according to the received selection information, so that the sorting bucket 31 corresponding to the identification number rotates to the standard position of the automatic sorting mechanism 30, and the sorting bucket door 08 is opened to take out the sorting bucket 31 at the standard position.

[0105] The rotation control in step 5 preferably adopts the shortest path control strategy shown in Table 1.

[0106] The intelligent medical cart of the present invention is a compact cart structure integrating multiple functions. The exterior adopts a multi-compartment humanized design. The interior is provided with an automatic pushing mechanism 10, an automatic scanning mechanism 20 and an automatic sorting mechanism 30 which are installed on a fixed support frame 50 and work in cooperation with each other.
