Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a transfer bed with a shock absorbing device. Background Art

[0002] A transfer bed is a special medical bed used to transfer patients between beds, as well as to transfer patients from the operating table to the ward and from the ambulance. The use of the transfer bed solves the difficulties of patients moving from the operating table to the ward after surgery, and reduces the pain and difficulty caused to patients by traditional manual transfers. It is used in all major hospitals and is an essential medical equipment in hospitals.

[0003] The Chinese patent application with patent application number CN202023024407.8 discloses a transfer bed with a shock-absorbing device. Although this application can reduce the amplitude through shock-proof airbags, thereby realizing the function of stable and low-vibration transfer vehicle, when this application is put into use, since only airbags are used for cushioning and shock absorption, the force generated during vibration cannot be evenly weakened, resulting in a phenomenon in which one side vibrates more and the other side vibrates less. Even if the injured patient on the transfer bed is subjected to a smaller vibration, he will suffer great pain due to the injury. Therefore, improvement is needed to address this problem.

[0009] According to the above technical solution, it also includes an anti-impact component, which is composed of a piston rod, a piston disc, an air pressure cylinder and air flow holes.

[0010] The piston rod is fixedly connected to the middle of the top of the lifting circular plate, the piston disc is fixedly connected to the top of the piston rod, the air pressure cylinder is fixedly connected to the middle of the top of the protective panel, the air flow hole is opened at the top outside the air pressure cylinder, and the piston disc can be lifted and lowered in the air pressure cylinder.

[0011] According to the above technical solution, the middle part of the connecting block 2 is rotatably connected to the middle part of the fixing frame 2, and the connecting block 2 can rotate in the middle part of the fixing frame 2, and an 8L oxygen cylinder can be placed in the cylinder.

[0012] According to the above technical solution, the top of the positioning frame is fixedly connected to the bottom of the protective panel, which can fix the position of the positioning frame.

[0013] According to the above technical solution, the bottom end of the lifting connecting rod passes through the bottom of the lifting guide cylinder and extends to the bottom of the lifting guide cylinder and is fixedly connected to the middle of the top of the fixed horizontal plate. The lifting connecting rod is slidingly connected to the bottom of the lifting guide cylinder.

[0014] According to the above technical solution, a sliding groove is opened in the lifting circular plate, and the lifting circular plate is slidingly connected to the outer wall of the lifting guide cylinder through the sliding groove.

When an overweight patient touches the mattress, the piston disc in the air cylinder is forced upward to generate compressed air, which limits the flow through precise holes to form an active air cushion support, completely eliminating the risk of instantaneous sinking of traditional transfer beds. 3. The four sets of air spring struts are arranged symmetrically, breaking down bump vibrations into multi-directional components and absorbing them synchronously, suppressing resonance effects and improving anti-bumping capabilities during movement; 4. By designing a linkage mechanism between the lifting circular plate and the rotating block, the air spring struts in four directions evenly disperse the impact force through deformation, converting vertical impact into controllable elastic potential energy, significantly improving the physical stability during transportation; 5. When the piston disc is under pressure, a throttling effect is formed through the air flow holes, which converts the instantaneous impact into a gradual displacement. When the piston disc rises, the negative pressure suction design makes the bed body reset process smooth and controllable. Regardless of bumpy road conditions or manual operation, the vibration amplitude of the bed surface can be kept small. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0023] For example 1, please refer to Figure 1-4 The present invention provides a technical solution: a transfer bed with a shock-absorbing device, including a universal movable wheel 1, and an auxiliary medical component 6. The top of the universal movable wheel 1 is fixedly connected to a support base frame 2, and the top of the support base frame 2 is fixedly connected to an electric lifting rod 3. The electric lifting rod 3 has a telescopic end, and the telescopic end of the electric lifting rod 3 is fixedly connected to a bed frame 4. A folding mattress 5 is provided on the top of the bed frame 4.

[0024] Among them, the auxiliary medical component 6 includes: Positioning installation frame 601, positioning installation frame 601 is fixedly connected to the outside of the bed frame 4, an electrocardiogram monitor 602 is clamped in the middle of the positioning installation frame 601, a fixing frame 1 603 is fixedly connected to the middle of the left bottom of the bed frame 4, a connecting plate 1 604 is rotatably connected to the middle of the fixing frame 1 603, a placing tube 605 is fixedly connected to the bottom of the connecting plate 1 604, a connecting block 2 606 is fixedly connected to the side of the placing tube 605 away from the connecting plate 1 604, a fixed horizontal plate 608 is fixedly connected to the middle of the left side of the fixed horizontal plate 608, a fixing frame 2 607 is fixedly connected to the middle of the left side of the fixed horizontal plate 608, the electric lifting rod 3 can drive the bed frame 4 to rise and fall when working, and the placing tube 605 at the bottom of the bed frame 4 can be adaptively rotated through the connecting plate 1 604 and the connecting block 2 606 when the bed frame 4 is rising and falling.

[0025] The middle part of the connecting block 2 606 is rotatably connected to the middle part of the fixing frame 2 607. The connecting block 2 606 can rotate in the middle part of the fixing frame 2 607. An 8L oxygen cylinder can be placed in the placement tube 605, so that the device will not cause damage to the 8L oxygen cylinder when in use, and the oxygen cylinder can change synchronously with the height change of the bed frame 4.

[0026] When the patient needs to be placed on the folding mattress 5, the electric lifting rod 3 is controlled to work. When the electric lifting rod 3 is working, it can drive the bed frame 4 to descend. At the same time, when the bed frame 4 descends, the fixed frame 1 603 descends synchronously. At the same time, the connecting plate 1 604 in the middle of the fixed frame 1 603 rotates. At the same time, the connecting block 2 606 on the other side of the placement cylinder 605 rotates in the fixed frame 2 607, which can make the placement cylinder 605 change its angle together to avoid affecting the oxygen cylinder in the placement cylinder 605.

[0027] For example 2, please refer to Figure 5 、 Figure 6 、 Figure 8 and Figure 9 On the basis of embodiment 1, the present invention provides a technical solution: it also includes a buffer assembly 7, which is composed of a connecting leg 701, a protective panel 702, a lifting guide cylinder 703, a spring 704, a lifting circular plate 705, a lifting connecting rod 706, a rotating block 1 707, an air spring support rod 708, a rotating block 2 709 and a positioning frame 710.

[0028] The connecting leg 701 is fixedly connected to the bottom of the bed frame 4, the protective panel 702 is fixedly connected to the bottom of the connecting leg 701, the lifting guide cylinder 703 is fixedly connected to the middle of the bottom of the protective panel 702, the spring 704 is fixedly connected to the top inside the lifting guide cylinder 703, the lifting circular plate 705 is fixedly connected to the bottom end of the spring 704, the lifting connecting rod 706 is fixedly connected to the middle of the bottom of the lifting circular plate 705, the rotating block 1 707 is rotatably connected to the outside of the lifting circular plate 705, the air spring strut 708 is fixedly connected to the side of the rotating block 1 707 away from the lifting guide cylinder 703, the rotating block 2 709 is fixedly connected to the end of the air spring strut 708 away from the lifting circular plate 705, the positioning frame 710 is rotatably connected to the middle of the rotating block 2 709, and the spring 704 can support the lifting circular plate 705.

[0029] The top of the positioning frame 710 is fixedly connected to the bottom of the protective panel 702, so as to fix the position of the positioning frame 710.

[0030] The bottom end of the lifting connecting rod 706 passes through the bottom of the lifting guide cylinder 703 and extends to the bottom of the lifting guide cylinder 703 and is fixedly connected to the middle of the top of the fixed horizontal plate 608. The lifting connecting rod 706 is slidingly connected to the bottom of the lifting guide cylinder 703. The lifting connecting rod 706 can be lifted and lowered in the lifting guide cylinder 703 as the universal moving wheel 1 and the support base frame 2 vibrate.

[0031] A sliding groove is provided inside the lifting circular plate 705, and the lifting circular plate 705 is slidingly connected to the outer wall of the lifting guide cylinder 703 through the sliding groove. A limiting groove is provided on the outer side of the lifting guide cylinder 703 to accommodate the movement of the lifting circular plate 705, and the lifting circular plate 705 can be lifted and lowered on the outer wall of the lifting guide cylinder 703.

[0032] There are four rotating blocks 1 707, air spring struts 708, rotating blocks 2 709 and positioning frames 710. The four rotating blocks 1 707, air spring struts 708, rotating blocks 2 709 and positioning frames 710 are distributed in a ring outside the lifting circular plate 705. When the lifting circular plate 705 is subjected to force, the force can be evenly distributed to four directions, so that the bottom of the bed frame 4 is evenly stressed.

[0033] When the transfer bed moves, it will be bumpy. At this time, the vibration on the universal moving wheel 1 and the supporting base frame 2 is transmitted upward. At this time, the spring 704 is compressed by the upward vibration of the lifting connecting rod 706. When the lifting connecting rod 706 moves upward, it can push the lifting circular plate 705 to rise. When the lifting circular plate 705 rises, the rotating block 1 707 can be rotated. At the same time, the rotating block 1 707 is subjected to force and squeezes the air spring strut 708. When the air spring strut 708 is subjected to force, it can absorb the vibration. Since the air spring strut 708 is arranged at the four directions of the lifting circular plate 705, the vibration can be evenly distributed in the four directions and buffered and reduced, ensuring that the body feel of the transfer bed is relatively stable when moving.

[0034] For example three, please refer to Figure 7 On the basis of the second embodiment, the present invention provides a technical solution: it also includes an anti-impact component 8, which is composed of a piston rod 801, a piston disc 802, an air pressure cylinder 803 and an air flow hole 804.

[0035] The piston rod 801 is fixedly connected to the middle of the top of the lifting circular plate 705, the piston disc 802 is fixedly connected to the top of the piston rod 801, the air cylinder 803 is fixedly connected to the middle of the top of the protective panel 702, and the air flow hole 804 is opened at the top outside the air cylinder 803. The piston disc 802 can be raised and lowered in the air cylinder 803.

[0036] The top end of the piston rod 801 passes through the top of the lifting guide cylinder 703, the middle of the protective panel 702 and the bottom of the pneumatic cylinder 803 and extends into the pneumatic cylinder 803 and is fixedly connected to the piston disk 802. When lifting, the lifting circular plate 705 can drive the piston disk 802 to lift and lower in the pneumatic cylinder 803 through the piston rod 801.

[0037] The lifting circular plate 705 can make the piston disc 802 move in the air cylinder 803 when rising and falling. When the piston disc 802 moves, it can be subjected to the resistance caused by the pressure change in the air cylinder 803, and absorb the impact generated by vibration, and can weaken the vibration generated during movement to ensure overall smooth operation.

[0038] When the road condition is bad and the transfer bed needs to be buffered, the bed frame 4 is bumped and caused to rise and fall. When the bed frame 4 falls, the protective panel 702 at the bottom of the bed frame 4 falls accordingly, which can make the air flow holes 804 and the protective panel 702 fall synchronously. In the process of the air flow holes 804 falling, the height of the lifting guide cylinder 703 falls. At this time, the lifting circular plate 705 on the top of the lifting connecting rod 706 rises relatively in the lifting guide cylinder 703, which can make the top of the lifting circular plate 705 move freely. The plug rod 801 pushes the piston disc 802, causing the piston disc 802 to move slowly in the air cylinder 803, and the air in the air cylinder 803 flows out evenly through the air flow holes 804, ensuring the stability of the bed frame 4 when it is descending. At the same time, when the bed frame 4 is ascending, the piston disc 802 can be pulled downward in the air cylinder 803, allowing the outside air to slowly enter the air cylinder 803 through the air flow holes 804 on the air cylinder 803, so that the bed frame 4 can be smoothly raised and lowered.

[0039] When a heavy patient is placed on the folding mattress 5, the folding mattress 5 is easily subjected to a large force due to the patient's excessive weight. When an ordinary transfer bed is placed on the bed surface of a heavy patient, the transfer bed as a whole will sink instantly due to the action of his own weight, causing secondary injuries to the patient if he is injured. When a heavy patient needs to be placed on the present device, the heavy patient applies an instantaneous force downward when contacting the folding mattress 5. At this time, the folding mattress 5 drives the protective panel 702 to drop instantly, which can cause the air cylinder 803 to drop instantly. At this time, the air cylinder 803 moves downward, forcing the piston disk 802 to move upward in the air cylinder 803, increasing the pressure on the upper side of the piston disk 802. At the same time, the pressure slowly flows out with the air flow hole 804, which can enable the folding mattress 5 to reduce the collision caused by the heavy patient during contact when placed on it, reduce the injuries caused, and make the device more applicable in a wider range of use.
