Description

Technical Field

[0001] This utility model relates to the field of medicine cabinet technology, and in particular to a medicine cabinet. Background Technology

[0002] In modern medical settings, the safety, accuracy, and timeliness of drug management are crucial factors in ensuring patient treatment outcomes and medication safety. This is especially true in settings such as outpatient injection rooms and allergy / desensitization treatment areas, where individualized medications (such as desensitization drugs) often require cryopreservation and administration by nurses at designated times. Currently, the existing methods for storing and retrieving these medications present the following problems:

[0003] Unstable storage environment:

[0004] Traditional drug storage often uses ordinary non-feedback refrigerators or insulated boxes, which lack real-time monitoring of temperature changes and alarm functions for abnormalities, making it difficult to meet the strict requirements for drug quality control.

[0005] Inefficient and error-prone medication dispensing:

[0006] Nurses have to manually search for medications, which is not only time-consuming and laborious, but also prone to problems such as mistaking or missing medications when multiple people use the same equipment, increasing the risk of medication use errors.

[0007] Low patient engagement:

[0008] According to the hospital's verification system, patients should participate in the medication verification process. However, most systems are currently led by medical staff, and patients lack a self-verification step, which affects the effectiveness of the system.

[0009] Therefore, there is an urgent need for an intelligent drug storage device with constant temperature refrigeration function, supporting accurate identification and automatic drug dispensing functions, in order to improve the safety, efficiency and humanization of drug management.

[0048] In this embodiment, the YZ discharging mechanism 130 includes a platform support 131 disposed on the lower surface of the loading platform 120, a discharging Y-axis drive module 132 that drives the platform support 131 to move left and right reciprocally, and a Z-axis drive module 133 that drives the discharging Y-axis drive module 132 to move up and down. Through the cooperation of the discharging Y-axis drive module 132 and the Z-axis drive module 133, the loading platform 120 can move up, down, left, and right within the discharging cavity 80 to cooperate with the XY transfer mechanism 140 of each layer for storing and retrieving drugs. Specifically, before use, the doctor prescribes the drugs needed for the patient. After the drug corresponding to the patient is stored, the patient enters their identity information through the facial recognition mechanism 100, which is then bound to the currently stored drug. When a patient needs medication, accompanied by a doctor, the patient confirms their identity and medication information through a facial recognition device 100. After confirmation, the system controls the XY transfer mechanism 140 and coordinates with the drug coding recognition device 150 to move the patient's corresponding medication to the front of the storage cavity 40. Then, the discharge Y-axis drive module 132 and Z-axis drive module 133 move the platform support 131 and the loading platform 120 to the front of the patient's medication storage cavity 40. The XY transfer mechanism 140 then places the medication on the loading platform. Further, the discharge Y-axis drive module 132 and Z-axis drive module 133 move the loading platform 120 to the medication retrieval window 90. At this point, the doctor or patient can retrieve the medication through the medication retrieval window 90.

[0049] In this embodiment, the Z-axis drive module 133 can be a commonly used lifting module such as a lead screw motor module, a motor-guide rail-belt module, or a linear motor module. Preferably, this embodiment uses a motor-guide rail-belt module, which includes a longitudinally arranged Z-axis guide rail body 1331, a Z-axis slide block 1332 slidably disposed on the Z-axis guide rail body 1331, a Z-axis drive belt 1333 that drives the Z-axis slide block 1332 to move longitudinally, and a Z-axis drive motor 133 that drives the Z-axis drive belt 1333 to rotate. 4; Two Z-axis guide rail bodies 1331 are provided and are located on the left and right sides of the loading cavity 80 respectively. The Z-axis drive motor 1334 is located on the top surface of the cabinet 10. The upper end of the Z-axis drive belt 1333 passes through the cabinet 10 and is connected to the rotating shaft of the Z-axis drive motor 1334. The Z-axis drive belts 1333 on the left and right sides are synchronously rotated through a drive shaft. Specifically, the Z-axis drive motor 1334 is arranged in the front and back direction and its rotating shaft is connected to the rotating shaft of the pulley of the Z-axis drive belt 1333 through a pair of meshing bevel gears.

[0050] In this embodiment, the discharge Y-axis drive module 132 includes a discharge Y-axis support optical shaft 1321 and a discharge Y-axis lead screw 1322 arranged parallel to each other from bottom to top, and a discharge Y-axis lead screw motor 1323 for driving the discharge Y-axis lead screw 1322 to rotate; the discharge Y-axis support optical shaft 1321 is fixedly connected to the movable terminal of the Z-axis drive module 133, i.e., the Z-axis slide 1332, and the discharge Y-axis lead screw 1322 is rotatably connected to the movable terminal of the Z-axis drive module 133; the platform The support 131 is threadedly connected to the discharge Y-axis lead screw 1322 and axially slidably connected to the discharge Y-axis support optical shaft 1321. During operation, the discharge Y-axis lead screw 1322 is driven to rotate by the discharge Y-axis lead screw motor 1323, which can drive the platform support 131 to move back and forth on the discharge Y-axis support optical shaft 1321 to match each column of storage slots 70 in each layer of storage cavity 40, so that the XY transfer mechanism 140 can transfer the medicine to the loading platform 120.

[0051] In this embodiment, the platform support 131 includes a support body 1311 with a rectangular parallelepiped structure, the long side of which is arranged in the left-right direction and the width direction is arranged in the up-down direction. A screw hole 131a adapted to the discharge Y-axis lead screw 1322 is provided through the support body 1311. The lower end of the front side wall of the support body 1311 is provided with a rearwardly recessed step 131b. A first matching groove 131c is provided on the step 131b corresponding to the discharge Y-axis support optical axis 1321. Furthermore, the platform support 131 also includes a positioning block detachably provided on the step 131b. 1312, the rear side wall of the positioning block 1312 is provided with a second adapting slide groove 131d corresponding to the discharge Y-axis support optical shaft 1321. The first adapting slide groove 131c and the second adapting slide groove 131d together form a guide hole for the discharge Y-axis support optical shaft 1321 to slide relative to the axial direction. Through the cooperation of the step 131b and the positioning block 1312, the installation, disassembly and maintenance of the discharge Y-axis support optical shaft 1321 can be facilitated. Moreover, by adjusting the locking screw of the positioning block 1312, the sliding damping of the loading platform 120 in the left and right directions can be adjusted.

[0052] In this embodiment, the XY transfer mechanism 140 includes a gripper module 141 for gripping drugs, a lifting module 142 for driving the gripper module 141 to move up and down, a rotating module 143 for driving the lifting module 142 to rotate horizontally, and an XY axis drive module 144 for driving the rotating module 143 to move forward, backward, left, and right. A horizontal extension arm 160 is provided on the movable terminal of the lifting module 142, and the gripper module 141 is located at the end of the extension arm 160. Through the cooperation of the extension arm 160 and the rotating module 143, not only can drugs in any position of the storage slot 70 in each storage cavity 40 be gripped, but also when the XY axis drive module 144 drives the lifting module 142 to reach the front of the storage cavity 40, the rotating module 143 can rotate the drugs and move them forward into the loading platform 120 in the discharge cavity.

[0053] In this embodiment, the XY axis drive module 144 includes an X-axis drive unit 14A and a Y-axis drive unit 14B.

[0054] The X-axis drive unit 14A includes an X-axis lead screw body A1 arranged in the front-to-back direction, an X-axis lead screw sleeve A2 axially slidably arranged on the X-axis lead screw body A1, and an X-axis lead screw motor A3 that drives the X-axis lead screw body A1 to rotate. There are two X-axis lead screw bodies A1, which are located on the left and right sides of the lower surface of the partition 50, respectively. The cabinet 10 has a mounting cavity 170 located on the rear side of the storage cavity 40. The X-axis lead screw motor A3 is located in the mounting cavity 170. The rear end of the X-axis lead screw body A1 extends into the mounting cavity 170 and is connected to the rotating shaft of the X-axis lead screw motor A3 for transmission. This design can effectively ensure the space utilization of the storage cavity 40 and avoid the installation of the X-axis lead screw motor A3 from occupying space in the storage cavity 40.

[0055] The Y-axis drive unit 14B includes a Y-axis lead screw B1 and a Y-axis support optical shaft B2 arranged side by side, a Y-axis lead screw motor B3 that drives the Y-axis lead screw B1 to rotate, and a Y-axis lead screw sleeve B4 adapted to be mounted on the Y-axis lead screw B1. The two ends of the Y-axis lead screw B1 are rotatably connected to the two X-axis lead screw sleeves A2, the two ends of the Y-axis support optical shaft B2 are fixedly connected to the two X-axis lead screw sleeves A2, and the Y-axis lead screw sleeve B4 is axially slidably connected to the Y-axis support optical shaft B2. The rotating module 143 is a motor and its housing is fixed to the lower end of the Y-axis lead screw sleeve B4. A rotating disk 180 is coaxially fixed on the lower rotating shaft of the rotating module 143, and a lifting module 142 is disposed on the lower surface of the rotating disk 180.

[0056] In this embodiment, the lifting module 142 includes a vertically arranged guide shaft 1421 and a lifting screw 1422, as well as a lifting screw motor 1423 for driving the lifting screw 1422 to rotate. The lifting screw motor 1423 is vertically mounted on the movable terminal of the rotating module 143, i.e., the turntable 180. The lower ends of the guide shaft 1421 and the lifting screw 1422 are connected by a connecting seat 190. The lifting screw 1422 is provided with a matching lifting screw sleeve 14C, and the extension arm 160 is detachably mounted on the lifting screw sleeve. On 14C; the lifting screw sleeve 14C is slidably connected to the guide shaft 1421. The connecting seat 190 not only fixes the guide shaft 1421 and the lifting screw 1422, but also prevents the lifting screw sleeve 14C from falling off. The lifting screw sleeve 14C is connected to the lifting screw 1422 and is also slidably connected to the guide shaft 1421. This arrangement can ensure the stability of the gripper module 141 in its up and down movement. The lifting screw 1422 not only plays a driving role, but also plays an auxiliary guiding role.

[0057] In this embodiment, the gripper module 141 includes a horizontally arranged fixed plate 1411, a fixed clamping plate 1412 vertically fixed to one end of the fixed plate 1411, a movable clamping plate 1413 vertically arranged at the other opposite end of the fixed plate 1411, and a gripping drive module 1414 for driving the movable clamping plate 1413 to move away from or closer to the fixed clamping plate 1412; the fixed plate 1411 is connected to the extension arm 160 through a connecting frame 190, and the gripping drive module 1414 is disposed on the upper surface of the fixed plate 1411; when assembled in place, the space between the lower ends of the fixed clamping plate 1412 and the movable clamping plate 1413 forms a gripping cavity 300 for gripping the drug.

[0058] The connecting frame 190 includes two first connecting rods 191 respectively located on the left and right sides of the clamping drive module 1414, a second connecting rod 192 located on the tail side of the clamping drive module 1414, and a diagonal tie rod 193 connecting the lower end of the second connecting rod 192 and the lifting screw sleeve 14C. The first connecting rod 191 and the second connecting rod 192 are both vertically fixed to the fixing plate 1411. The upper end of the second connecting rod is vertically fixed to the extension arm. The diagonal tie rod 193 is located below the extension arm. The diagonal tie rod, the first connecting rod, and the second connecting rod cooperate to form a triangular component, which can disperse the downward pulling force applied by the gripper module 141 to the extension arm to the lifting screw sleeve 14C through the diagonal tie rod to ensure the stability of the structure.

[0059] During material handling, the clamping drive module 1414 drives the movable clamping plate 1413 away from the fixed clamping plate 1412, causing the clamping cavity to expand to its maximum stroke. Then, the lifting module 142 drives the fixed plate 1411 to descend into position, allowing the outer packaging of the drug to enter the clamping cavity. Subsequently, the movable clamping plate 1413, driven by the clamping drive module 1414, approaches the fixed clamping plate 1412 and clamps the drug. At this time, the lifting module 142 rises again to reset. Then, the XY axis drive module 144 moves the drug to the front of the storage cavity 40. After it is in position, the rotation module 143 drives the lifting mechanism and the gripper module 141 to rotate horizontally, adjusting the position of the drug to be directly above the loading platform 120 in the dispensing cavity. Then, the lifting mechanism descends again to bring the drug closer to the loading platform 120. After it is in position, the clamping drive module 1414 drives the movable clamping plate 1413 away from the fixed clamping plate 1412, so that the drug can be placed on the loading platform 120 for dispensing.

[0060] In this embodiment, the clamping drive module 1414 is an electric cylinder; a positioning seat 200 is fixed on the upper surface of the fixing plate 1411 at the front side of the clamping drive module 1414. The positioning seat 200 is provided with a guide limiting hole (not shown) that matches the movable shaft of the clamping drive module 1414. After the movable shaft of the clamping drive module 1414 slides through the guide limiting hole, it is vertically connected to the movable clamping plate 1413. The positioning seat 200 and the guide limiting hole can ensure that the movable rod of the clamping drive module 1414 runs smoothly.

[0061] In this embodiment, the upper end of the movable clamping plate 1413 has an upward extension 14D. A hollow shaft 210 facing the positioning seat 200 is vertically fixed on the extension 14D. A movable shaft 220 is provided on the side of the hollow shaft 210 facing the positioning seat 200. The movable shaft 220 extends into the hollow shaft 210 and is coaxially threaded to it. A buffer pad 230 is provided at the end of the movable shaft 220 facing the positioning seat 200. Through the movable shaft 220 coaxially threaded to the hollow shaft 210, the retraction stroke of the clamping drive module 1414 can be adaptively adjusted to avoid excessive clamping force on large-volume drugs. Moreover, the component composed of the extension 14D, the hollow shaft 210, and the movable shaft 220 can also prevent the movable rod of the clamping drive module 1414 from being subjected to excessive upward deflection force when clamping drugs, ensuring that the movable rod of the clamping drive module 1414 can still maintain accurate coaxiality after long-term use.

[0062] In this embodiment, the drug coding identification mechanism 150 is disposed on the lower surface of the fixing plate 1411 to facilitate quick and accurate identification of the code on the outer packaging of the drug. With the cooperation of the face recognition mechanism 100, it can be ensured that each drug access is uniquely bound to the corresponding patient. Compared with the method of manually accessing drugs, the risk of wrong access or incorrect information binding can be avoided.

[0063] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
