Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a medical trolley with stackable refrigerated medicine boxes. Background Technology

[0002] In the field of medical equipment technology, refrigerated medicine boxes and medical carts are indispensable equipment in hospitals, clinics, and drug transportation, especially in the storage and transportation of vaccines, biological agents, and special drugs, where strict requirements exist for temperature control and transportation stability. However, existing refrigerated medicine boxes and medical carts typically have several defects and shortcomings: First, traditional refrigerated medicine boxes are mostly designed independently and cannot be flexibly stacked or combined, resulting in low space utilization. Especially in medical settings with limited space, stacking multiple medicine boxes can easily lead to the risk of tipping over or collision. In addition, traditional medical carts lack effective shock absorption and cushioning mechanisms during transportation. Especially when moving on uneven ground, vibrations can easily be transmitted to the inside of the medicine box, potentially damaging temperature-sensitive drugs (such as vaccines and insulin). Utility Model Content

[0003] The purpose of this invention is to provide a medical trolley with stackable refrigerated medicine boxes, which aims to solve the technical problems of existing medicine boxes not being able to be stacked flexibly and the damage to the internal medicines caused by vibration during transportation.

[0004] To achieve the above objectives, this utility model provides a medical trolley with stackable refrigerated medicine boxes, including...

[0005] A square medicine box, comprising at least one square medicine box, wherein a sliding door is movably provided on one side of the square medicine box, and a hollow sleeve is provided on the edge of the side wall of the square medicine box, the sleeve being vertically upward; a refrigeration unit is provided inside the square medicine box, and a buffer unit is provided at the bottom of the square medicine box;

[0006] The trolley includes a support plate with four vertically arranged connecting rods on top. The area formed by the four connecting rods is adapted to the bottom area of ​​the square medicine boxes. The sleeves corresponding to multiple square medicine boxes can be sequentially fitted into the corresponding connecting rods from top to bottom to stack multiple square medicine boxes on the trolley. The square medicine boxes are isolated from each other by a buffer unit. The bottom of the trolley has an airbag, and a pad is connected above the airbag. The pad contacts the square medicine box at the bottom. A push handle is provided on one side of the trolley, and rollers are provided at the four corners of the lower end of the trolley.

[0007] Furthermore, the square medicine box is provided with a horizontal clamp and a vertical clamp inside. The horizontal clamp divides the inner chamber of the square medicine box into an equal upper cavity and a lower cavity, and the refrigeration unit is located in the upper cavity. The vertical clamp is provided at the middle of the lower cavity, and the vertical clamp divides the lower cavity into a lower left cavity and a lower right cavity. There are connecting openings between the upper cavity, the lower left cavity, and the lower right cavity.

[0008] Furthermore, the sleeves of the multiple square medicine boxes have the same structure, and the length of the sleeve is longer than the height of the square medicine box, so that the end of the sleeve that extends beyond the top of the square medicine box is provided with an upper tube section, and the end of the sleeve that extends beyond the top of the square medicine box is provided with a lower tube section.

[0009] Furthermore, the buffer unit is a soft silicone layer, one end of which is connected to the bottom of the upper square medicine box, and the other end is in contact with the top of the lower square medicine box.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, a medical trolley for stackable refrigerated medicine boxes is mentioned, including a square medicine box 100 and a trolley 200. The square medicine box 100 has at least one square medicine box, and a sliding door 110 is movably provided on one side of the square medicine box 100. The edge of the side wall of the square medicine box 100 is provided with a hollow sleeve 120, which is vertically upward. The trolley 200 includes a support plate 210, and four vertically arranged connecting rods 220 are provided above the support plate 210. The area formed by the four connecting rods 220 is adapted to the bottom area of ​​the square medicine box 100. The sleeves 120 corresponding to the multiple square medicine boxes 100 can be sequentially fitted into the corresponding connecting rods 220 from top to bottom to stack the multiple square medicine boxes 100 on the trolley 200. If the staff needs to transport the medicine boxes, the sleeves 120 of the side wall edge (i.e., prism) of the medicine box are fitted onto the connecting rods 220 to stabilize the medicine box. If multiple medicine boxes need to be transported, the sleeves 120 of several medicine boxes are sequentially inserted into the connecting rod 220 from top to bottom to complete the stacking. The bottom of the square medicine box 100 is equipped with a buffer unit 140, which can buffer vibrations caused by friction between adjacent medicine boxes. The square medicine box 100 is equipped with a refrigeration unit 130, which can store low-temperature medicines. Activating the refrigeration unit 130 allows the inside of the medicine box to reach and maintain a stable temperature preset by the temperature sensor 160. The bottom of the trolley 200 is equipped with an airbag 230, and a pad 240 is connected above the airbag 230, which contacts the lowest-level square medicine box 100. When medications need to be transported, the operator moves the trolley 200 by pushing the handle 300. The wheels 270 contact the ground, and the airbags 230 at the bottom of the trolley 200 absorb shock on bumpy surfaces. The cushioning effect is then transferred to the bottom medicine box via the pad 240. The buffer units 140 between the medicine boxes further attenuate vibration transmission, ensuring the stability of the medications during transport. Upon arrival at the destination, medications can be accessed directly through the sliding doors 110 of the medicine boxes, or parts of the medicine boxes can be disassembled for individual use as needed. The separate design of the sleeve 120 and connecting rod 220 facilitates quick assembly and disassembly. The entire workflow addresses the synergistic needs of medication refrigeration, stable transportation, and flexible operation, significantly improving efficiency and safety in medical settings.

[0029] Furthermore, the square medicine box 100 is provided with a transverse clamping plate 150 and a longitudinal clamping plate 151 inside. The transverse clamping plate 150 divides the inner chamber of the square medicine box 100 into an equal upper cavity 152 and a lower cavity 153. The refrigeration unit 130 is arranged in the upper cavity 152. The lower cavity 153 is provided with a longitudinal clamping plate 151 at the middle. The longitudinal clamping plate 151 divides the lower cavity 153 into a lower left cavity 154 and a lower right cavity 155. There are connecting ports 156 between the upper cavity 152, the lower left cavity 154, and the lower right cavity 155. The connecting ports 156 can be connecting ports 156 on the transverse clamping plate 150 and the longitudinal clamping plate 151. When the refrigeration unit 130 (such as a semiconductor cooling chip or compressor refrigeration system) is activated, cold air first circulates within the upper cavity 152 and then diffuses downwards through the connecting port 156 to the lower left cavity 154 and lower right cavity 155, ensuring a uniform temperature distribution throughout the entire medicine box. Simultaneously, the separation design of the transverse clamps 150 and longitudinal clamps 151 allows medicines to be stored in layers according to category or temperature requirements. For example, the upper cavity 152 stores vaccines or biological agents with strict temperature requirements, while the lower left cavity 154 and lower right cavity 155 store ordinary refrigerated medicines or spare consumables. When the trolley 200 moves, the longitudinal clamps 151 also provide support, preventing medicines from scattering and colliding due to vibration.

[0030] Furthermore, the sleeves 120 of the multiple square medicine boxes 100 have identical structures, and the length of the sleeve 120 is longer than the height of the square medicine box 100. This results in an upper tube portion 250 at the end of the sleeve 120 extending above the square medicine box 100, and a lower tube portion 251 at the end of the sleeve 120 extending above the square medicine box 100. Because the length of the sleeve 120 is greater than the height of the medicine box, a gap is left between adjacent medicine boxes after stacking, avoiding direct contact and reducing vibration transmission. Simultaneously, the buffer unit 140 is a soft silicone layer. One end of the soft silicone layer is connected to the bottom of the previous square medicine box 100, and the other end contacts the top of the next square medicine box 100, allowing the soft silicone layer to absorb vibrations from the road surface through elastic deformation.

[0031] Furthermore, the airbag 230 is corrugated. When the trolley 200 moves on uneven surfaces, the corrugated airbag 230 adapts to the undulations of the ground through its own expansion and contraction, thereby reducing the vibration transmitted to the medicine box.

[0032] Furthermore, a fixing sleeve 260 is provided on the outer wall of the connecting rod 220, and the fixing sleeve 260 is connected to the upper end of the support plate 210. The fixing sleeve 260 is fixed to the outside of the connecting rod 220 by means of threads or snaps, which enhances the connection strength between the connecting rod 220 and the support plate 210 and prevents the connecting rod 220 from loosening or deforming due to uneven force during the movement of the trolley 200.

[0033] Furthermore, the push handle 300 includes two uprights 320, which are respectively arranged parallel to each other on the support plate 210. One end of each of the two crossbars 330 is connected to the two uprights 320, and the other end of each crossbar 330 is connected to the push rod 310, thereby improving operability.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
