Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and in particular to a flatbed side-mounted ventilator fixed transport frame. Background Technology

[0002] Current stretchers are generally not designed with a pre-installed interface for securing the ventilator. Clinically, the following temporary solutions are commonly used: ① Placing the ventilator at the foot or side of the stretcher and connecting it to the patient via an extended tubing. However, the height difference between the equipment and the stretcher makes the tubing prone to twisting or detachment due to bumps; ② Using straps to secure the ventilator to the stretcher railing. However, the lack of dedicated clamps results in poor stability, and frequent disassembly and reassembly reduce efficiency; ③ Medical staff manually support the ventilator, but prolonged transport can lead to fatigue and increase the risk of human error. None of these methods achieve a rigid connection between the ventilator and the stretcher, making relative movement between the equipment difficult to eliminate, and they also have poor compatibility.

[0003] The traditional method of separating ventilators from stretchers not only increases the risk of tubing traction due to the distance between the devices, making them prone to dislodgement accidents during bumps or sudden stops, but also requires ventilators to occupy additional passageway space or rely on manual support, which obstructs the operating vision and movement path of medical staff and increases manpower burden. At the same time, stretchers lack dedicated fixing structures, and the temporary straps, hooks and other simple devices used are poorly adapted and difficult to stably fix the ventilator, making them prone to loosening and slippage. Furthermore, the lack of standardized design makes the existing solution difficult to be compatible with diverse clinical scenarios and equipment requirements, and the overall safety and efficiency urgently need to be improved.

[0004] Therefore, there is an urgent need for a specialized device that can be tightly integrated with a flatbed cart and stably securely fix the ventilator to solve the problems of equipment separation, tubing traction, space occupation, and unstable fixation in existing technologies. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies that separate the ventilator from the transport cart. These methods not only increase the risk of tubing traction due to the distance between the equipment, making it prone to dislodgement during bumps or sudden stops, but also require additional passageway space or manual support for the ventilator, hindering the operator's view and movement path, and increasing manpower burden. Furthermore, the lack of a dedicated fixing structure on the transport cart, and the poor adaptability of temporary straps, hooks, and other simple devices, make it difficult to stably fix the ventilator, leading to loosening and slippage. The lack of standardized design further complicates the existing solutions, making them incompatible with diverse clinical scenarios and equipment requirements. Overall safety and efficiency urgently need improvement. Therefore, this invention proposes a transport cart-mounted ventilator fixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flatbed side-mounted ventilator fixed transport frame includes an aluminum alloy frame. The top of the aluminum alloy frame is open. One side of the aluminum alloy frame has a ventilator wiring connection channel for discharging the ventilator's wires. The other side of the aluminum alloy frame has a ventilator display screen display channel for displaying the ventilator's display screen.

[0008] The bed frame body has side bed panels fixedly connected to both sides. The top of the side bed panels has multiple limiting grooves. A connecting component is provided on the top of one side of the aluminum alloy frame. The connecting component is used to install the aluminum alloy frame on one side of the side bed panel.

[0009] A stabilizing component is provided at the bottom of one side of the aluminum alloy frame. The stabilizing component is used to improve the stability of the connection between the side bed board and the aluminum alloy frame.

[0010] In one possible design, the connecting assembly includes a second fixed side plate fixedly connected inside the aluminum alloy frame, a first fixed side plate fixedly connected to one side of the aluminum alloy frame, two symmetrically arranged threaded rods passing through the internal threads of the first fixed side plate, a threaded knob fixedly connected to one end of each threaded rod, and one side of the threaded knob abutting against one side of the side bed board and used to connect the side bed board and the aluminum alloy frame.

[0011] In one possible design, a fixing circular plate is fixedly sleeved on the outer wall of the threaded rod, and the fixing circular plate abuts against the limiting groove.

[0012] In one possible design, the stabilizing component includes a connecting side plate slidably connected to one side of the aluminum alloy frame, with a supporting base plate fixedly connected to one side bottom of the connecting side plate, the top of the supporting base plate abutting against the bottom of the bed frame body.

[0013] In one possible design, multiple slots are provided on the inner walls of both sides of the aluminum alloy frame, and two symmetrically arranged side fixing blocks are fixedly connected to one side of the connecting side plate. A rectangular cavity is provided inside the side fixing block, and a plug rod slides through the rectangular cavity. The plug rod engages with the slot.

[0014] In one possible design, one end of the insertion rod is fixedly connected to a protruding plate, and a common compression spring is provided between the two protruding plates on their sides that are close to each other. The two ends of the compression spring abut against one side of the protruding plate through spring seats.

[0015] In one possible design, the bed frame body has legs fixedly connected to both sides of its bottom, and each leg has casters with brakes fixedly installed on both sides of its bottom.

[0016] In one possible design, a silicone anti-slip pad is adhered to the bottom inner wall of the aluminum alloy frame, the silicone anti-slip pad being used to support the ventilator.

[0017] In this application, during use, the support base plate is first moved to the lowest point, the device is moved to one side of the side bed board, the aluminum alloy frame is moved to the upper side of the side bed board, and the fixed circular plate is moved down from above the limiting groove and engaged. The threaded knob is rotated, and the threaded knob drives the threaded rod to rotate. The threaded rod moves inside the first fixed side plate, which in turn drives the threaded knob to move laterally. One side of the threaded knob abuts against the inner side of the side bed board. At the same time, the fixed circular plate is supported inside the limiting groove to ensure the stability of the threaded rod. One side of the second fixed side plate is used to seal one end of the threaded rod to prevent one end of the threaded rod from protruding and causing damage to the ventilator or the staff.

[0018] After installation, pull the two protruding plates. The protruding plates compress the springs and move the two insert rods closer together. One end of the two insert rods moves out of the slot, which releases the braking state between the connecting side plate and the aluminum alloy frame. Adjust the height of the connecting side plate upwards. The connecting side plate moves the support base plate upwards. The top of the support base plate abuts against the bottom of the side bed board, which ensures the stability of the device. Placing the ventilator on top of the silicone anti-slip mat also provides cushioning and makes it convenient to use.

[0019] Beneficial effects: Spiral adjustable clamping structure: The clamping width is adjusted by rotating a threaded knob to accommodate different flatbed lathe thicknesses.

[0020] Ventilator display screen: A transparent observation window is opened on the side of the frame to ensure that medical staff can view the ventilator parameters in real time during transport.

[0021] Centralized management channel for ventilator circuits: This channel houses power cords, sensor wires, and gas tubing to prevent tangling or accidental pulling.

[0022] Silicone anti-slip pads and shock-absorbing base: The contact surface is covered with a thick medical silicone pad to increase the coefficient of friction and prevent the ventilator from sliding.

[0023] The ventilator and the stretcher are locked together as a whole by rigid clamping, eliminating the risk of tube dislodgement caused by tubing traction.

[0024] The quick-release design saves a lot of time compared to traditional strap fixation.

[0025] Adjustable clamping structure + shock-absorbing base covers 99% of flatcar types and transport road conditions.

[0026] The ventilator is automatically secured to the stretcher without the need for special personnel to support it, reducing the need for transport staff and improving nursing efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-5 The main structure of the transfer frame consists of an aluminum alloy frame 3 and a bed frame body 5. The aluminum alloy frame 3 is welded from lightweight aluminum alloy profiles. Its top opening is designed so that the ventilator (not shown in the diagram) can be directly inserted. The bottom inner wall is fixed with a silicone anti-slip pad 12 by silicone adhesive to increase the friction of the bottom of the ventilator.

[0036] A ventilator display screen 14 is provided on one side of the aluminum alloy frame 3. The channel is a rectangular hollow structure and its size is adapted to the operation area of ​​the ventilator display screen, so that medical staff can directly observe the display screen parameters and perform touch operation. A ventilator wiring connection channel 13 is provided on the other side. The channel is a strip hole and is used to lead out the ventilator wiring diagram (not shown) and connect it to external equipment.

[0037] The assembly method for the connecting components is as follows:

[0038] A first fixed side plate 15 is welded to the top of the aluminum alloy frame 3 on the side near the bed frame body 5. Two M8 threaded holes are machined inside the plate. The connecting assembly includes a second fixed side plate 16 that is fixedly connected inside the aluminum alloy frame 3.

[0039] Two threaded rods 9 are screwed into the threaded holes respectively. The outer wall of the threaded rods 9 is fixedly fitted with a fixed circular plate 8 through an interference fit. The diameter of the fixed circular plate 8 matches the width of the limiting groove 6 on the top of the side bed plate 1.

[0040] Rotating the threaded knob 7 causes the fixed circular plate 8 to be embedded in the limiting groove 6, and the axial movement of the threaded rod 9 achieves a tight connection between the aluminum alloy frame 3 and the side bed plate 1.

[0041] The shape of the fixed circular plate 8 can be as follows: 1. Gear-shaped edge circular plate: the outer circumference is machined with a sawtooth structure, which meshes with the tooth groove of the inner wall of the limiting groove (6) to prevent horizontal displacement; 2. Telescopic protrusion circular plate: spring steel balls are embedded in the plate surface, and the protrusions automatically pop out when they contact the limiting groove to realize multi-point positioning; 3. Eccentric adjustment circular plate: the clamping distance is finely adjusted by rotating the eccentric disc to adapt to the asymmetrical bed frame structure; 4. Multi-segment folding circular plate: the split design with hinge connection is adopted, which covers a large area of ​​groove after unfolding and is easy to disassemble when shrinking.

[0042] The adjustment process of the stabilizing component includes: sliding the connecting side plate 11 up and down along the slide groove (not shown in the figure) on the side wall of the aluminum alloy frame 3, adjusting the support base plate 10 to the position of contacting the bottom of the bed frame body 5, and fixing two symmetrically arranged side fixing blocks 17 on one side of the connecting side plate 11. The side fixing blocks 17 have a rectangular cavity 22 inside.

[0043] Manually press the protruding plate 18 at the end of the insertion rod 20 to disengage the insertion rod 20 from the current slot 19. After release, compress the spring 21 to push the insertion rod 20 into the selected slot 19 to complete the height locking.

[0044] The support base plate 10 is made of L-shaped bent steel plate, and its top is in surface contact with the bottom surface of the bed frame body 5 to enhance the lateral support stability.

[0045] This application can be used in the field of ventilators, or in other fields applicable to this application.

[0046] Example 2

[0047] refer to Figure 1-5 An improvement upon Example 1 is the development of a flatbed-mounted ventilator transport frame, applied to the field of ventilators. The main body 5 of the frame is supported by legs 2, with casters 4 equipped with brakes installed at the bottom of the legs 2 for easy overall transport. In actual use, after placing the ventilator into the aluminum alloy frame 3, the tubing is connected via the wiring channel 13, and the display screen is housed via the display channel 14, thus achieving integrated transport of the ventilator and the flatbed.

[0048] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
