Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a protective infusion stand designed specifically for elderly patients, aiming to provide a safer, more convenient and comfortable infusion experience. Background Art

[0002] Elderly patients receiving infusion therapy often face numerous inconveniences due to declining physical function, such as limited mobility, difficulty adjusting the height of the IV stand, and a lack of comfortable support during the infusion. Traditional IV stands often feature simple designs and limited functionality, making them inadequate for meeting the specific needs of elderly patients. Therefore, developing an IV stand that overcomes these limitations and provides comprehensive protection and support is crucial.

[0003] For example, patent publication number CN112618848B describes an IV stand with protective features. However, the focus is primarily on the basic structure and height adjustment features of the IV stand, lacking design considerations for the specific needs of elderly patients. For example, there are no specific protective measures to prevent elderly patients from falling during infusions due to discomfort or unconsciousness, demonstrating insufficient care for this special population.

[0004] For example, patent publication number CN118045251B describes an IV stand for geriatric nursing. This device primarily focuses on general infusion functionality and basic ease of use, without specifically addressing the specific needs of elderly patients. For example, it fails to consider the frailty, mobility issues, and poor manual dexterity that elderly patients may face, and lacks features like auxiliary support, heating, and emergency call functions, failing to provide comprehensive and attentive nursing services for elderly patients. Summary of the Invention

[0005] The purpose of the present invention is to provide a protective infusion stand suitable for elderly patients. Through innovative design, the height and angle of the infusion stand can be adjusted, and armrests and heating functions are added to improve the safety and comfort of elderly patients during the infusion process.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is: a protective infusion stand suitable for elderly patients, including a base, a support frame installed on the base, the support frame is a hollow rectangular parallelepiped with an open top, and reinforcing ribs are installed at the four corners of the inner wall of the support frame. The cross-section of the reinforcing ribs is square, and rectangular grooves are provided on the central axes of the two corresponding sides of the support frame. A screw is provided inside the support frame at the corresponding position of the rectangular groove, and the screw is fixedly installed on the base. A fixing block is sleeved on the screw, and a telescopic arm is fixedly connected to the fixing block. A slide is provided inside the telescopic arm, and the slide is a two-section stepped slide. An extension arm is installed inside the telescopic arm, and a hook is installed on the extension arm. A limit block is provided on the extension arm near the end of the telescopic arm. A rotating head is provided on the other two sides of the support frame, and an armrest is fixedly connected to the rotating head. A top cover is provided on the top of the support frame.

[0007] As an improvement, a counterweight is provided inside the base to increase the stability of the infusion stand and prevent it from tipping over.

[0008] As an improvement, the large-size section of the slide and the limit block are clearance-matched, the small-size section and the extension arm are clearance-matched, and several sealing gaskets are provided at the connection to ensure smooth and stable movement, and several sealing gaskets are provided at the connection to prevent dust and moisture from entering.

[0009] As an improvement, the slide is connected to an air pipe near the end of the telescopic arm, the air pipe is connected to an air pump, and the air pump is installed on the top of the base. The air pressure generated by the air pump pushes the extension arm to move in the slide, thereby achieving rapid adjustment.

[0010] As an improvement, a motor is installed on the side of the fixed block, and a gear is installed on the motor shaft. The gear and the screw are engaged. The motor drives the gear to rotate, driving the fixed block to move up and down along the screw to achieve height adjustment of the telescopic arm.

[0011] As an improvement, a heating pad is built into the end of the armrest. The heating pad is a resistance heater that can be turned on as needed to provide warmth for the hands of elderly patients and prevent them from getting cold during infusion.

[0012] As an improvement, the rotating head rotates at an angle of degrees, and the armrests are stored vertically upwards in the storage state, saving space and making it easy to move and store.

[0013] As an improvement, the air pump, motor and heating pad are connected to the power supply through wires. The power supply is installed on the top of the base. The air pump, motor and heating pad are controlled by a control panel. The control panel is installed at the bottom of the armrest on one side of the support frame for direct operation by the patient.

[0014] As an improvement, a speaker is installed on the top of the support frame on the control panel side to play operation prompts, alarm information and call medical staff, etc.

[0015] As an improvement, a pressure sensor is installed on the top of the heating pad on the top surface of the armrest and connected to the control chip of the control panel. When the elderly patient leans on the armrest, the pressure sensor senses the pressure change and displays or sounds a prompt through the control panel to remind medical staff to pay attention to the patient's condition.

[0016] The advantages of this invention over existing technologies include: The protective IV stand, through its innovative design, allows for flexible height and angle adjustment, along with the addition of armrests and a heating function, significantly improving the safety and comfort of elderly patients during infusions. Furthermore, intelligent features such as electric and pneumatic adjustment and pressure monitoring further enhance the device's practicality and convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] In a specific implementation of the present invention, a protective infusion stand suitable for elderly patients includes a base 1, characterized in that:

[0026] Base and Support Structure: Mounted on base 1 is support frame 2, a hollow rectangular parallelepiped with an opening at the top, for supporting and securing other components. Ribs 3 are installed at the four corners of the inner wall of support frame 2 to enhance structural stability. Ribs 3 have a square cross-section for easy installation and securing.

[0027] Adjustment mechanism: Rectangular grooves 4 are provided on the central axis of the two corresponding sides of the support frame 2. A screw 5 is provided inside the support frame 2 at the position corresponding to the rectangular groove 4. The screw is vertically arranged inside the support frame and is located on the center line of the rectangular groove to facilitate the extension of the handrail. The screw 5 is fixedly installed on the base 1. A fixed block 6 is sleeved on the screw 5. The fixed block is used to connect the telescopic arm, the screw and the motor so that the gear at the end of the motor can engage with the screw to achieve lifting. A telescopic arm 7 is fixedly connected to the fixed block 6 to adjust the height of the infusion stand. A slide 8 is provided inside the telescopic arm 7. The slide 8 is a two-section stepped slide used to accommodate and fix the extension arm 9. The extension arm is directly installed inside the slide. Both adopt a square cross-section to provide a limit to ensure that the hook is always facing upwards.

[0028] Infusion hook: An extension arm 9 is installed inside the telescopic arm 7, and a hook 10 is installed on the extension arm 9 for hanging an infusion bottle. A limit block 11 is provided near the end of the telescopic arm 7 to prevent the extension arm 9 from sliding out excessively.

[0029] Armrest design: The other two sides of the support frame 2 are provided with rotating heads 12, and the rotating heads 12 are fixedly connected with armrests 13 to provide support for elderly patients. The design of the armrests 13 takes ergonomics into consideration to ensure that they will not feel tired even after long-term use.

[0030] Top cover and safety protection: A top cover 14 is provided on the top of the support frame 2 to protect the internal mechanical structure and increase the overall aesthetics.

[0031] Base counterweight: A counterweight is provided inside the base 1 to improve the stability of the infusion stand and prevent it from tipping over.

[0032] Slide and seal: The wide section of the slide 8 and the limit block 11 are in clearance fit, while the narrow section and the extension arm 9 are in clearance fit, ensuring smooth and stable movement. Several sealing gaskets are installed at the joints to prevent dust and moisture from entering.

[0033] Pneumatic adjustment: The end of the chute 8 near the telescopic arm 7 is connected to the air pipe 15, which is connected to the air pump 16. The air pump 16 is installed on the top of the base 1. The air pressure generated by the air pump 16 pushes the extension arm 9 to move in the chute 8 to achieve rapid adjustment.

[0034] Electric adjustment: A motor 17 is mounted on the side of the fixed block 6, and a gear 18 is mounted on the rotating shaft of the motor 17. The gear 18 meshes with the screw 5. The motor 17 drives the gear 18 to rotate, driving the fixed block 6 to move up and down along the screw 5 to achieve the height adjustment of the telescopic arm 7.

[0035] Heated armrest: A heating pad 19 is built into the end of the armrest 13. The heating pad 19 is a resistance heater that can be turned on as needed to provide warmth for elderly patients.

[0036] The armrest can be rotated and stored: the rotating head 12 rotates at an angle of 90 degrees, and the armrest 13 is stored vertically upward in the storage state, which saves space and is easy to move and store.

[0037] Power supply and control: The air pump 16, motor 17 and heating pad 19 are connected to the power supply 20 through wires, and the power supply 20 is installed on the top of the base 1. All devices are controlled by the control panel 21, which is installed at the bottom of the armrest 13 on one side of the support frame 2 for easy operation.

[0038] Audio prompts: A speaker 22 is installed on the top of the support frame 2 on the side of the control panel 21, which is used to play operation prompts, alarm information, etc.

[0039] Pressure Monitoring: A strain-gauge pressure sensor (BF350-3AA) is installed on the top of the heating pad 19 on the top surface of the armrest 13 and is connected to the control chip on the control panel. When an elderly patient leans on the armrest, the pressure sensor senses the pressure change and displays a warning or sounds an alarm on the control panel, alerting medical staff to the patient's condition.

[0040] Working principle of the present invention:

[0041] Regulation mechanism:

[0042] Height adjustment: The motor drives the gear to engage with the screw, which enables the fixed block to move up and down on the screw, thereby driving the height adjustment of the telescopic arm.

[0043] Angle adjustment: There is a self-locking device at the hinge of the armrest. When it is adjusted to the appropriate angle, the motor stops to lock the angle.

[0044] Heated armrests: The heating pads inside the armrests work on the principle of resistive heating, providing warm support for elderly patients.

[0045] Pressure monitoring and prompts: The pressure sensor on the top of the armrest can sense the pressure changes when the patient leans in real time, and issue prompts through the control panel to remind medical staff to pay attention to the patient's condition.

[0046] Basic functions of the control panel

[0047] A control panel is typically a device that integrates various control buttons, switches, and a display screen. It receives user commands and converts them into corresponding electrical signals. In the IV stand of the present invention, the control panel is mounted at the bottom of the armrest on one side of the support frame, making it easier for medical staff to operate.

[0048] Control Principle

[0049] Power connection:

[0050] The air pump 16 , the motor 17 and the heating pad 19 are all connected to a power supply 20 via wires, and the power supply 20 is mounted on the top of the base 1 .

[0051] The control panel 21 is also connected to the power supply 20 for receiving electric energy provided by the power supply and distributing the electric energy to various controlled devices.

[0052] Signal transmission:

[0053] When a user presses a button or switch on the control panel, the control panel receives an electrical signal.

[0054] This signal is then converted into corresponding control instructions and transmitted to the corresponding controlled device (such as an air pump, motor or heating pad) through internal circuits.

[0055] Device response:

[0056] After receiving the control instruction, the controlled device will perform corresponding operations according to the instruction.

[0057] For example, when the control panel issues an instruction to start the air pump, the air pump starts to work, generating air pressure to push the extension arm to move in the slide.

[0058] Likewise, when the control panel issues a command to heat the armrests, the heating pads begin heating up to provide warmth to the patient.

[0059] Control method

[0060] Manual Control:

[0061] Users can directly control the air pump, motor and heating pad on and off through buttons or switches on the control panel.

[0062] This method is simple and intuitive, and is suitable for situations where the device status needs to be adjusted quickly.

[0063] Program Control:

[0064] There may be some preset programs inside the control panel to implement more complex control logic.

[0065] For example, a program can be set to automatically turn on a heating pad during a specific time period, or automatically adjust the height of an IV pole when a pressure sensor signal is detected.

[0066] Security and reliability

[0067] To ensure that the control panel's control of the air pump, motor, and heating pad is safe and reliable, the following aspects generally need to be considered:

[0068] Circuit design: Use reliable circuit design to ensure stable signal transmission and normal operation of the equipment.

[0069] Overload protection: Add an overload protection device to the circuit to prevent the equipment from being damaged due to overload.

[0070] Fault detection: The control panel should be able to detect the operating status of the controlled equipment in real time and issue an alarm in time when a fault occurs.

[0071] User rights management: For operations that require specific permissions to perform (such as modifying program settings), a corresponding user rights management mechanism should be set up.

[0072] In summary, the control panel controls the air pump, motor, and heating pad through pre-set programs and circuit connections. Users can operate these devices directly using buttons or switches on the control panel, or they can implement more complex control logic using pre-set programs. To ensure safe and reliable control, circuit design, overload protection, fault detection, and user rights management also need to be considered.

[0073] Example:

[0074] Example 1:

[0075] A protective infusion stand suitable for elderly patients includes a base, a support frame, reinforcing ribs, a rectangular groove, a screw, a fixing block, a telescopic arm, a slide, an extension arm, a hook, a limit block, a rotating head, an armrest, a top cover and other components.

[0076] In this embodiment, a counterweight is installed inside the base to enhance the stability of the IV stand. The coordinated design of the chute, extension arm, and stopper ensures smooth movement and secure positioning of the extension arm within the chute. A built-in heating pad at the end of the armrest provides warmth for the patient. Furthermore, the armrest is connected to the support frame via a swivel head, allowing for 90-degree rotation and storage, saving space.

[0077] During use, medical staff can adjust the height and angle of the IV stand via the control panel based on the patient's height and needs. When the patient needs to lean on it, the armrests provide support, while the heating pad provides warmth. A pressure sensor monitors the patient's leaning status in real time and issues prompts through the control panel to alert medical staff.

[0078] Example 2:

[0079] This embodiment is similar to the basic structure of embodiment 1, but is further optimized and upgraded on this basis.

[0080] In this embodiment, in addition to the basic adjustment, heating and monitoring functions, an audio prompt function is added, a speaker is installed, and a sensor is installed on the armrest, directly connected to the motor and heater. When the height, angle or heating status of the infusion stand changes, the speaker on the control panel will emit a corresponding prompt sound to alert medical staff and patients.

[0081] In addition, this embodiment also uses more advanced motor and air pump control technology to achieve more precise and smoother adjustment effects. At the same time, the material and shape of the armrests have also been optimized to be more ergonomically designed, providing patients with a more comfortable leaning experience.

[0082] During use, medical staff can easily adjust the height and angle of the IV stand and control the armrest heating through the touch screen or remote control on the control panel. At the same time, the audio prompt function can also promptly remind medical staff and patients of various changes during the infusion process.

[0083] The above two embodiments both demonstrate the specific application and effects of the protective IV stand of the present invention for elderly patients. Through innovative design and the application of intelligent technology, the present invention significantly improves the safety and comfort of elderly patients during infusion.
