Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically to an intelligent electric sealed delivery vehicle. Background Technology

[0002] With the continuous improvement and development of my country's medical standards, the requirements for sterilization supply work are also increasing. Furthermore, reports indicate that over 70% of hospitals in my country have nurses comprising more than 50% of their sterilization supply center staff. These nurses are responsible not only for meticulous cleaning, sterilization, and packaging, but also for high-intensity material handling and even transportation. Transporting heavy sterile instruments such as orthopedic devices requires frequent bending over for loading and unloading, posing a significant challenge to sterilization supply workers.

[0003] Currently, sealed delivery vehicles mainly rely on manual labor, resulting in low transportation efficiency and insufficient safety protection measures. The main issues are:

[0004] 1. Speed ​​is difficult to control when going uphill, downhill, and turning;

[0005] 2. The loading rack of the delivery vehicle is low, requiring staff to frequently bend over when loading and unloading equipment, which is time-consuming and laborious;

[0006] 3. Repeated opening and closing of the doors can easily damage the rotating shaft connection, causing the doors to fall off, disrupting the sealed state of the transport vehicle, and potentially causing secondary contamination of sterile items, thus affecting their use.

[0007] In view of this, the inventors have designed an intelligent electric sealed delivery vehicle to solve the above problems. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent electric sealed delivery vehicle. Its advantages are that it is suitable for the complex environment of hospitals, can be intelligently lifted and lowered, has imperceptible electric power assistance, and can disinfect the surface of the items in the sealed compartment during transportation, and has good application prospects.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an intelligent electric sealed delivery vehicle, comprising a basket body with an opening at the top.

[0010] A tiered shelf is installed inside the basket to hold sterile instruments and seal the opening of the basket.

[0011] The intelligent disinfection device is installed inside the basket and is used to disinfect sterile instruments, and disinfection is performed according to the status of the tiered shelves.

[0012] The intelligent lifting device is installed inside the basket and is used to drive the tiered storage rack to move vertically and adjust its height according to the lifting situation.

[0013] The intelligent drive device is located at the lower end of the basket body to assist the movement of the basket body and to adjust the speed according to uphill and downhill conditions.

[0014] The MCU controller, located inside the basket and equipped with a battery and touch screen, is used to control the intelligent disinfection device, intelligent lifting device, and intelligent drive device, and can be controlled through system settings.

[0015] By adopting the above technical solution, when medical staff need to use the sealed delivery cart, the MCU controller can control the intelligent lifting device to move the tiered shelf upwards from inside the cart body and out of the cart body opening, and raise it to a designated height as needed. Then, medical staff place sterile instruments on the tiered shelf, and the MCU controller controls the intelligent lifting device to move the tiered shelf into the cart body. When the tiered shelf carrying sterile instruments moves into the cart body, it seals the sterile instruments inside the cart body, and the MCU controller controls the intelligent disinfection device to disinfect the sterile instruments. When medical staff push the sealed delivery cart uphill, the MCU controller controls the intelligent drive device to intelligently assist the cart body in climbing, so that only one medical staff member is needed to push it. When medical staff push the sealed delivery cart downhill, the MCU controller controls the intelligent drive device to intelligently assist the cart body in descending the slope, and can intelligently limit the speed during the pushing process and brake in case of sudden acceleration.

[0016] In summary, the combination of the basket body, tiered storage rack, intelligent disinfection device, intelligent lifting device, intelligent drive device, and MCU controller allows medical staff to conveniently place sterile instruments on the tiered storage rack without squatting. The sterile instruments placed on the tiered storage rack are intelligently disinfected on the basket body, and the system provides assistance when climbing or descending slopes, reducing the effort required by medical staff and preventing accidents caused by the basket body sliding down too quickly. Thus, it is suitable for the complex environment of hospitals, features intelligent lifting, imperceptible electric assistance, and can disinfect the surface of items in the sealed compartment during transportation, showing good application prospects.

[0017] The present invention is further configured such that: the intelligent disinfection device includes an ultraviolet disinfection lamp disposed on a tiered shelf, an abutment limit switch disposed on the basket body and used to abut the tiered shelf, and a relay module disposed on the basket body and used to control the ultraviolet disinfection lamp; the abutment limit switch is electrically connected to an MCU controller, the MCU controller is electrically connected to the relay module, and the relay module is electrically connected to the ultraviolet disinfection lamp.

[0018] By adopting the above technical solution, the disinfection time can be set through the touch screen on the MCU controller before sterilizing the sterile instruments. After the layered shelf seals the opening of the basket body, the layered shelf abuts against the limit switch. The limit switch transmits an electrical signal to the MCU controller. After receiving the signal, the MCU controller transmits the electrical signal to the relay, which controls the ultraviolet disinfection lamp to disinfect the sterile instruments. The ultraviolet disinfection lamp can also be turned off after the set time is reached through the setting of the MCU controller.

[0019] The present invention is further configured such that: the abutment limit switch is disposed on the inner wall of the opening of the basket body; when the layered shelf seals the opening of the basket body, the layered shelf abuts against the abutment limit switch and the ultraviolet disinfection lamp is turned on under the action of the MCU controller.

[0020] By adopting the above technical solution, the abutment limit switch is set on the inner wall of the opening of the basket body, which facilitates later maintenance.

[0021] The present invention is further configured as follows: the intelligent lifting device includes a scissor-type lifting mechanism disposed within the basket body and used to drive the vertical movement of the tiered shelf; a lifting motor disposed within the basket body and used to provide power to the scissor-type lifting mechanism; a shelf height photoelectric sensor disposed within the basket body and electrically connected to the MCU controller; upper and lower limit switches disposed within the basket body and electrically connected to the MCU controller; a weight sensor disposed between the scissor-type lifting mechanism and the tiered shelf and electrically connected to the MCU controller; and a motor drive module disposed within the basket body and used to control the lifting motor. The shelf height photoelectric sensor is disposed on the inner wall of the basket body and used to measure the rising height of the tiered shelf. The upper and lower limit switches are disposed at the bottom of the basket body and contact the bottom of the tiered shelf to activate. The weight sensor is disposed on the inner wall of the basket body and used to detect sterile instruments on the tiered shelf.

[0022] By adopting the above technical solution, when the tiered shelving needs to be raised, the lifting height can be set via the MCU controller. The MCU controller transmits an electrical signal to the motor drive module, which controls the lifting motor to rotate, causing the lifting motor to drive the scissor lift mechanism, thereby moving the tiered shelving upwards. When the tiered shelving is raised to the specified height, the shelf height photoelectric sensor detects the height of the tiered shelving and transmits the signal to the MCU controller. The MCU controller then controls the lifting motor to stop rotating via the motor drive module. When sterile instruments are placed on the tiered shelving, the weight sensor measures the weight of the tiered shelving and transmits the signal to the MCU controller for recording. When the tiered shelving needs to be lowered, it can be controlled via M... The CU controller sets the descent height, and the MCU controller transmits an electrical signal to the motor drive module. The motor drive module controls the lifting motor to rotate, which in turn drives the scissor lift mechanism, thus lowering the tiered storage rack. When the tiered storage rack reaches its highest height, it triggers the upper and lower limit switches mounted on the basket body. These switches transmit signals to the MCU controller, which then uses the motor drive module to stop the lifting motor. When the tiered storage rack reaches its lowest height, it triggers another upper and lower limit switch mounted on the basket body. This switch also transmits signals to the MCU controller, which again uses the motor drive module to stop the lifting motor.

[0023] The present invention is further configured such that: a push handle is provided on the outer wall of the basket body, and a manual switching switch electrically connected to the MCU controller and used to control the motor drive module is provided on the push handle.

[0024] By adopting the above technical solution, when it is necessary to manually raise and lower the tiered shelf, the manual switch can be pressed, so that the manual switch transmits the signal to the MCU controller. When medical staff lift the tiered shelf by hand, the MCU controller will control the lifting motor to rotate through the motor drive module. The scissor lift mechanism can assist medical staff in providing appropriate lifting force, thereby facilitating the lifting of the tiered shelf.

[0025] The present invention is further configured as follows: the intelligent drive device includes two drive wheels and two steering wheels disposed at the lower end of the basket body for driving the basket body to move, a speed detector disposed on the drive wheels and electrically connected to the MCU controller, a motor drive module disposed on the basket body and electrically connected to the drive wheels, a battery brake disposed on the basket body for locking the drive wheels, a battery brake drive module disposed on the basket body and electrically connected to the battery brake, a brake release switch disposed on the basket body and electrically connected to the MCU controller, and a motion direction sensor disposed on the basket body and electrically connected to the MCU controller. The brake release switch issues commands to the battery brake drive module and controls the battery brake through the MCU controller. The motion direction sensor is used to detect the rotation direction of the steering wheels and transmit the signal to the MCU controller. The motor drive module issues rotation direction to the drive wheels under the command of the MCU controller. The speed detector is used to detect the speed of the drive wheels.

[0026] By adopting the above technical solution, when the basket needs to be pushed, the motion direction sensor can transmit the detected signal to the MCU controller. The MCU controller then controls the drive wheel to rotate through the motor drive module, which can assist medical staff in pushing the basket by applying auxiliary thrust. When the drive wheel rotates, the speed detector can detect the rotation speed of the drive wheel and feed it back to the MCU controller. After data processing, the MCU controller can control the drive wheel to reach the speed corresponding to the medical staff, thus efficiently assisting them in pushing the basket. When going uphill, the drive wheel can apply an auxiliary force to the basket's movement, and when going downhill, it can apply a reverse force to prevent the basket from sliding downhill quickly. Furthermore, if the drive wheel speed is too high during climbing or descending, the speed detector can detect the rotation speed of the drive wheel and feed it back to the MCU controller. The MCU controller can then control the battery brake to apply emergency braking to the drive wheel through the battery brake drive module. When it is necessary to release the battery brake to apply emergency braking to the drive wheel, the release brake switch can be pressed. The release brake switch transmits a signal to the MCU controller, which can then control the battery brake to release through the battery brake drive module.

[0027] In summary, this utility model has the following advantages:

[0028] 1. By combining the basket body, tiered storage rack, intelligent disinfection device, intelligent lifting device, intelligent drive device, and MCU controller, medical staff can conveniently place sterile instruments on the tiered storage rack without squatting. The sterile instruments placed on the tiered storage rack are intelligently disinfected on the basket body, and it provides assistance when climbing uphill and downhill, reducing the effort of medical staff and preventing the basket body from sliding down too quickly and causing accidents. Thus, it is suitable for the complex environment of hospitals, with intelligent lifting, imperceptible electric assistance, and surface disinfection of items in the sealed compartment during transportation, showing good application prospects.

[0029] 2. Before sterilizing sterile instruments, the sterilization time is set via the touch screen on the MCU controller. After the tiered shelf seals the opening of the basket body, the tiered shelf abuts against the limit switch. The limit switch transmits an electrical signal to the MCU controller. After receiving the signal, the MCU controller transmits the electrical signal to the relay, which controls the ultraviolet disinfection lamp to sterilize the sterile instruments. The ultraviolet disinfection lamp can also be turned off after the set time is reached through the MCU controller settings. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] A smart electric sealed delivery vehicle, such as Figure 1 , 2 As shown, it includes a basket body 1 with an opening at the top.

[0038] A tiered shelf 2 is installed inside the basket body 1 to hold sterile instruments and seal the opening of the basket body 1;

[0039] The intelligent disinfection device is installed inside the basket body 1 to disinfect sterile instruments and to disinfect according to the status of the layered shelf 2.

[0040] An intelligent lifting device is installed inside the basket body 1 to drive the tiered storage rack 2 to move vertically and adjust its height according to the lifting situation;

[0041] An intelligent drive device is installed at the lower end of the basket body 1 to assist the movement of the basket body 1 and to adjust the speed according to uphill and downhill conditions.

[0042] The MCU controller 3, installed inside the basket body 1 and equipped with a battery and touch screen, is used to control the intelligent disinfection device, intelligent lifting device and intelligent drive device, and can be controlled through system settings.

[0043] like Figure 2 , 3 As shown, the intelligent disinfection device includes an ultraviolet disinfection lamp 4 installed on the tiered shelf 2, an abutment limit switch 5 installed on the basket body 1 and used to abut against the tiered shelf 2, and a relay module installed on the basket body 1 and used to control the ultraviolet disinfection lamp 4. The abutment limit switch 5 is electrically connected to the MCU controller 3, the MCU controller 3 is electrically connected to the relay module, and the relay module is electrically connected to the ultraviolet disinfection lamp 4.

[0044] Before using the intelligent disinfection device to disinfect sterile instruments, the disinfection time is set via the touch screen on the MCU controller 3. When the layered shelf 2 seals the opening of the basket body 1, the layered shelf 2 abuts against the limit switch 5. The limit switch transmits an electrical signal to the MCU controller 3. After receiving the signal, the MCU controller 3 transmits the electrical signal to the relay, which controls the ultraviolet disinfection lamp 4 to disinfect the sterile instruments. The ultraviolet disinfection lamp 4 can be turned off after the set time is reached, as set by the MCU controller 3.

[0045] Furthermore, such as Figure 2 As shown, the abutment limit switch 5 is installed on the inner wall of the opening of the basket body 1. When the layered shelf 2 seals the opening of the basket body 1, the layered shelf 2 abuts against the abutment limit switch 5 and the ultraviolet disinfection lamp 4 is turned on under the action of the MCU controller 3.

[0046] like Figure 2 ,4 As shown, the intelligent lifting device includes a scissor lift mechanism 7 installed inside the basket body 1 for driving the vertical movement of the tiered shelf 2, a lifting motor 8 installed inside the basket body 1 for providing power to the scissor lift mechanism 7, a shelf height photoelectric sensor 9 installed inside the basket body 1 and electrically connected to the MCU controller 3, an upper and lower limit switch 10 installed inside the basket body 1 and electrically connected to the MCU controller 3, a weight sensor 11 installed between the scissor lift mechanism 7 and the tiered shelf 2 and electrically connected to the MCU controller 3, and a motor drive module installed inside the basket body 1 for controlling the lifting motor 8. The shelf height photoelectric sensor 9 is installed on the inner wall of the basket body 1 and is used to measure the rising height of the tiered shelf 2. The upper and lower limit switch 10 is installed at the bottom inside the basket body 1 and contacts the bottom of the tiered shelf 2 to activate. The weight sensor 11 is installed on the inner wall of the basket body 1 and is used to detect sterile instruments on the tiered shelf 2.

[0047] When the tiered shelf 2 needs to be raised, the lifting height can be set via the MCU controller 3. The MCU controller 3 transmits an electrical signal to the motor drive module, which controls the lifting motor 8 to rotate, causing the lifting motor 8 to drive the scissor lift mechanism 7, thereby moving the tiered shelf 2 upwards. When the tiered shelf 2 is raised to the specified height, the shelf height photoelectric sensor 9 detects the height of the tiered shelf 2 and transmits the signal to the MCU controller 3. The MCU controller 3 then controls the lifting motor 8 to stop rotating via the motor drive module. When sterile instruments are placed on the tiered shelf 2, the weight sensor 11 measures the weight of the tiered shelf 2 and transmits the signal to the MCU controller 3 for recording. When the tiered shelf 2 needs to be lowered, the lifting height can be set via the MCU controller 3. When the height is lowered, the MCU controller 3 transmits an electrical signal to the motor drive module, which controls the lifting motor 8 to rotate. This causes the lifting motor 8 to drive the scissor lift mechanism 7, thereby lowering the tiered shelf 2. When the tiered shelf 2 rises to its highest height, it touches the upper and lower limit switches 10 installed on the basket body 1. The upper and lower limit switches 10 transmit signals to the MCU controller 3, which then controls the lifting motor 8 to stop rotating via the motor drive module. When the tiered shelf 2 falls to its lowest height, it touches another upper and lower limit switch 10 installed on the basket body 1. This upper and lower limit switch 10 transmits signals to the MCU controller 3, which then controls the lifting motor 8 to stop rotating via the motor drive module.

[0048] Furthermore, a push handle 13 is installed on the outer wall of the basket body 1. A manual switch 14, which is electrically connected to the MCU controller 3 and used to control the motor drive module, is installed on the push handle 13. When it is necessary to manually raise and lower the tiered shelf 2, the manual switch 14 can be pressed, so that the manual switch 14 transmits a signal to the MCU controller 3. When medical staff lift the tiered shelf 2 by hand, the MCU controller 3 will control the lifting motor 8 to rotate through the motor drive module. The scissor lift mechanism 7 can assist medical staff in providing appropriate lifting force, thereby facilitating the lifting of the tiered shelf 2.

[0049] like Figure 2 , 5 As shown, the intelligent drive device includes two drive wheels 15 and two steering wheels 16 mounted on the lower end of the basket body 1 for moving the basket body 1, a speed detector 17 mounted on the drive wheels 15 and electrically connected to the MCU controller 3, a motor drive module mounted on the basket body 1 and electrically connected to the drive wheels 15, a battery brake 19 mounted on the basket body 1 for locking the drive wheels 15, a battery brake drive module 20 mounted on the basket body 1 and electrically connected to the battery brake 19, a brake release switch 21 mounted on the basket body 1 and electrically connected to the MCU controller 3, and a motion direction sensor 22 mounted on the basket body 1 and electrically connected to the MCU controller 3. The brake release switch 21 sends commands to the battery brake drive module 20 and controls the battery brake 19 through the MCU controller 3. The motion direction sensor 22 is used to detect the rotation direction of the steering wheels 16 and transmit the signal to the MCU controller 3. The motor drive module sends rotation directions to the drive wheels 15 under the command of the MCU controller 3. The speed detector 17 is used to detect the speed of the drive wheels 15.

[0050] When the basket body 1 needs to be pushed, the motion direction sensor 22 transmits the detected signal to the MCU controller 3. The MCU controller 3 then controls the drive wheel 15 to rotate via the motor drive module. This provides auxiliary thrust to help medical personnel push the basket body 1. Furthermore, as the drive wheel 15 rotates, the speed detector 17 detects the rotational speed of the drive wheel 15 and feeds it back to the MCU controller 3. After data processing, the MCU controller 3 controls the drive wheel 15 to reach the speed corresponding to the medical personnel's current position, thus efficiently assisting them in pushing the basket body 1. When going uphill, the drive wheel 15 can provide climbing assistance to the basket body 1, and when going downhill, the drive wheel 15 can provide additional force to the basket body 1. The movement of body 1 applies a counterforce to prevent the basket body 1 from sliding down the slope quickly. During the uphill or downhill process, if the drive wheel 15 rotates too fast, the speed detector 17 can detect the rotation speed of the drive wheel 15 and feed it back to the MCU controller 3. The MCU controller 3 can control the battery brake 19 to perform emergency braking on the drive wheel 15 through the battery brake drive module 20 via the data. When it is necessary to contact the battery brake 19 to perform emergency braking on the drive wheel 15, the release brake switch 21 can be pressed. The release brake switch 21 transmits a signal to the MCU controller 3, and the MCU controller 3 can then control the battery brake 19 to release via the battery brake drive module 20 via the data.

[0051] The working process and beneficial effects of this utility model are as follows: When medical staff need to use the sealed delivery cart, the MCU controller 3 can control the intelligent lifting device to move the layered shelf 2 from inside the cart body 1 upwards out of the opening of the cart body 1, and raise it to a specified height as needed. Then, the medical staff places the sterile instruments on the layered shelf 2, and the MCU controller 3 controls the intelligent lifting device to move the layered shelf 2 into the cart body 1. When the layered shelf 2 carrying sterile instruments moves into the cart body 1, the layered shelf 2 seals the sterile instruments inside the cart body 1, and the MCU controller 3 controls the intelligent disinfection device to disinfect the sterile instruments. When the medical staff pushes the sealed delivery cart uphill, the MCU controller 3 controls the intelligent drive device to intelligently assist the cart body 1 in climbing, so that only one medical staff member needs to push it. When the medical staff pushes the sealed delivery cart downhill, the MCU controller 3 controls the intelligent drive device to intelligently assist the cart body 1 in descending, and can intelligently limit the speed during the pushing process and brake when there is sudden acceleration.

[0052] In summary, the combination of the basket body 1, the tiered storage rack 2, the intelligent disinfection device, the intelligent lifting device, the intelligent drive device, and the MCU controller 3 allows medical staff to conveniently place sterile instruments on the tiered storage rack 2 without having to squat. The sterile instruments placed on the tiered storage rack 2 are intelligently disinfected on the basket body 1, and the basket body 1 provides assistance when climbing or descending slopes, reducing the effort required by medical staff and preventing the basket body 1 from sliding down too quickly and causing accidents. Thus, it is suitable for the complex environment of hospitals, with intelligent lifting, imperceptible electric assistance, and the ability to disinfect the surface of items in the sealed compartment during transportation, showing good application prospects.
