Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a transport device for the care of critically ill pregnant women. Background Art

[0002] In the medical field, the transfer of critically ill pregnant women has always been a crucial part of the medical treatment process. Because pregnant women may suffer from serious diseases during pregnancy, delivery or within 42 days after delivery due to various complex factors, these diseases are often sudden and high-risk. Therefore, the timely and safe transfer of critically ill pregnant women has become the key to ensuring the safety of mother and baby.

[0003] Traditional transport methods have many shortcomings when dealing with critically ill pregnant women. On the one hand, ordinary ambulances or transport vehicles often lack professional medical equipment and nursing staff, and cannot provide effective monitoring and treatment during the transport process, which may cause the patient's condition to worsen or an accident to occur. On the other hand, the bumps and vibrations during the transport process may also have adverse effects on pregnant women and fetuses, increase the risk of transport, and the transport process needs to be fast. At this time, too fast transport may easily cause the transport vehicle to overturn, and when passing a steep slope, the transport vehicle will also tilt due to the steep slope, which may easily cause the pregnant woman on the transport vehicle to tilt and slide. Summary of the invention

[0004] The present application proposes a transfer device for the care of critically ill pregnant women and mothers, which has the advantages of shock absorption through shock-absorbing springs, vibration reduction through the flow of hydraulic oil, automatic angle adjustment of the shock-absorbing bracket facing different terrains through the articulation of the shock-absorbing bracket, reducing the impact range of vibration to a single shock-absorbing bracket through the articulation of the shock-absorbing bracket, and automatic adjustment of the angle of the bed board through the articulation mode of the bed board, and is used to solve the problem that the existing transfer beds have poor vibration reduction and cannot effectively adapt to different terrains.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a transfer device for the care of critically ill pregnant women and mothers, comprising a bed frame and a bed board located in the bed frame; a wrapping groove is opened in the bed frame, the bottom of the wrapping groove forms a bottom plate, and a hydraulic cylinder I is arranged at the four corners of the top of the bottom plate, and a sealing piston rod I is movably sleeved in the hydraulic cylinder I, and the top of the sealing piston rod I is fixedly connected to a connecting rod I, and the top of the connecting rod I is fixedly connected to an articulated ball I, and the articulated ball I is hinged to the bottom end of the bed board; ball hinge seats are fixedly connected to the four corners of the bottom end of the bed frame, and a shock-absorbing bracket is hinged below the ball hinge seat for reducing vibration force and vibration amplitude, and a universal wheel is arranged at the bottom end of the shock-absorbing bracket.

[0006] Preferably, the bed board is movably sleeved in the wrapping groove, and there is a gap between the side wall of the bed board and the groove wall of the wrapping groove, providing sufficient space for the movement of the bed board.

[0007] Preferably, the shock-absorbing bracket includes a hydraulic cylinder II located below the ball hinge seat, a sealing piston rod II movably sleeved in the inner cavity of the hydraulic cylinder II, a support rod arranged at the bottom end of the sealing piston rod II, and a shock-absorbing spring arranged between the opposite ends of the hydraulic cylinder II and the support rod.

[0008] Preferably, a connecting rod II is provided at the top of the hydraulic cylinder II, and an articulated ball II is provided at the top of the connecting rod II. The articulated ball II is hinged to the ball articulated seat and is used to automatically adjust the angle to reduce the range of vibration.

[0009] Preferably, the inner cavity of the hydraulic cylinder II forms a liquid storage cavity, and a hose is provided on the top of the liquid storage cavity, and one end of the hose away from the hydraulic cylinder II is connected to the bottom of the hydraulic cylinder I which is close thereto.

[0010] Preferably, symmetrical hinged seats are respectively arranged on the side walls of the relative hydraulic cylinder II, symmetrical hinged seats are respectively arranged on the side walls of the two relative support rods, an hinged rod is arranged between the two relative hinged seats, and both ends of the hinged rod are respectively hinged to the two relative hinged seats for controlling the movement range of the shock-absorbing bracket.

[0011] Preferably, sliding cavities are opened in the four sides of the top of the bed frame, a partition layer is arranged in the center of the sliding cavity, counterweight springs are arranged at both ends of the partition layer, a counterweight block is connected to the end of the counterweight spring away from the partition layer, and the counterweight block is slidably sleeved in the sliding cavity to adjust the weight around the bed frame.

[0012] The present application provides a transfer device for the care of critically ill pregnant women and mothers. The device converts the upward vibration force into the upward movement of the sealing piston rod II through a support rod, so that the shock-absorbing spring is compressed to perform a shock absorption, and at the same time squeezes the hydraulic oil in the liquid storage chamber, so that the squeezed hydraulic oil is pressed into the hydraulic cylinder I through a hose. Due to the small diameter of the hose, a damping force is generated. The oil releases a large amount of heat during the flow process and converts kinetic energy into thermal energy, effectively absorbing and dissipating vibration energy, so that the body of the vehicle quickly returns to a stable state and reduces the amplitude and frequency of the bed board's jumping under vibration.

[0013] At the same time, when the transfer bed moves to the inclined ramp, the bed frame will tilt along with the inclined ramp. At this time, the counterweight block will slide in the downward direction. The greater the inclination angle, the farther the counterweight block slides in the downward direction, making the bed frame heavier in the downward position due to the inclination, which will squeeze the hydraulic cylinder II below the bed frame downward, causing the hydraulic cylinder II to squeeze the connected shock-absorbing spring downward, causing the sealing piston rod II here to move upward relatively, pushing the hydraulic oil in the hydraulic cylinder II into the connected hydraulic cylinder I through the connected hose, pushing the sealing piston rod I to lift, and driving the bed board to lift upward, thereby keeping the bed board in a relatively horizontal state, improving the safety of the patient when facing the inclined ramp.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Embodiment 1

[0024] See also Figure 1 to Figure 2 , including a rectangular bed frame 1, a wrapping groove 2 is opened in the bed frame 1, a bed board 13 is movably connected in the wrapping groove 2, there is a gap between the side wall of the bed board 13 and the groove wall of the wrapping groove 2, so that the bed board 13 is always located in the wrapping groove 2, and the existence of the gap provides sufficient space for the bed board 13 to move relative to the wrapping groove 2.

[0025] See also Figure 1 to Figure 2The bottom of the groove 2 is wrapped to form a bottom plate 3, and the four corners of the top of the bottom plate 3 are fixedly connected with a hydraulic cylinder Ⅰ9, and a sealing piston rod Ⅰ10 is movably sleeved in the hydraulic cylinder Ⅰ9. The top of the sealing piston rod Ⅰ10 is fixedly connected with a connecting rod Ⅰ11, and the top of the connecting rod Ⅰ11 is fixedly connected with a hinge ball Ⅰ12. The hinge ball Ⅰ12 is hinged to the bottom end of the bed board 13, so that when the patient lies on the bed board 13, the patient's own weight will drive the bed board 13 to press down, so that the bed board 13 drives the sealing piston rod Ⅰ10 to press down, so that the sealing piston rod Ⅰ10 presses the hydraulic oil in the hydraulic cylinder Ⅰ9 into the hydraulic cylinder Ⅱ through the hose 18 15, a downward force is applied to the sealing piston rod Ⅱ20, and an upward force is applied to the hydraulic cylinder Ⅱ15. At this time, since the universal wheel 22 is in contact with the ground, there is no space for the support rod 19 and the sealing piston rod Ⅱ20 to move downward, so that the hydraulic cylinder Ⅱ15 drives the entire bed frame 1 to move upward. At this time, the shock-absorbing spring 21 is stretched, causing the bed board 13 to sink into the wrapping groove 2 until the tension of the shock-absorbing spring 21 and the power provided by the patient's own weight tend to be balanced, and the movement stops. The patient is protected by the side wall of the wrapping groove 2, and at the same time, the patient's position height is lowered, the center of gravity of the entire transfer bed is lowered, and the stability is improved.

[0026] See also Figure 1 , Figures 3 to 5The four corners of the bottom end of the bed frame 1 are fixedly connected with a ball hinge seat 14, and a shock-absorbing bracket is hinged below the ball hinge seat 14. The shock-absorbing bracket includes a hydraulic cylinder II 15 located below the ball hinge seat 14, a sealing piston rod II 20 movably sleeved in the inner cavity of the hydraulic cylinder II 15, a support rod 19 fixedly connected to the bottom end of the sealing piston rod II 20, and a shock-absorbing spring 21 fixedly connected between the opposite ends of the hydraulic cylinder II 15 and the support rod 19, so that when the transfer bed is traveling on an uneven ground, the support rod 19 will The uneven ground causes vibration. Taking the convex ground as an example, the support rod 19 will be affected by the convex ground and move upward. The distance between the support rod 19 and the hydraulic cylinder II 15 is reduced, causing the stretched shock-absorbing spring 21 to be compressed. At this time, the support rod 19 will drive the sealing piston rod II 20 to squeeze the hydraulic oil in the hydraulic cylinder II 15 upward, pushing the hydraulic oil to flow into the hydraulic cylinder I 9. At this time, due to the small diameter of the hose 18, a damping force is generated. The oil will release a lot of heat during the flow process and convert kinetic energy into It is transformed into heat energy, effectively absorbing and dissipating vibration energy. At the same time, the flow state of this hydraulic oil will slow down the recovery of the shock-absorbing spring 21, so that the vehicle body quickly returns to a stable state and reduces the amplitude and frequency of the bed board's vibration. It should be noted that in the process of the sealing piston rod Ⅱ20 squeezing the hydraulic oil in the hydraulic cylinder Ⅱ15 upward and pushing the hydraulic oil to flow into the hydraulic cylinder Ⅰ9, the hydraulic oil in the hydraulic cylinder Ⅰ9 will increase, pushing the sealing piston rod Ⅰ10 to move upward. Since the hydraulic cylinder Ⅰ9 is not connected, when only one support rod 19 jumps due to external force, only the sealing piston rod Ⅰ10 related to this support rod 19 will move upward. Affected by the hinge ball Ⅰ12, at this time, only the part of the bed board 13 at the hinge of the lifted sealing piston rod Ⅰ10 will move upward, that is, only one corner of the bed board 13 will move obliquely upward, rather than the entire bed board 13 moving upward in a large range, thereby improving the patient's stability and safety by controlling the range of large-amplitude vibration.

[0027] See also Figure 3 The top of the hydraulic cylinder Ⅱ15 is fixedly connected with a connecting rod Ⅱ16, and the top of the connecting rod Ⅱ16 is fixedly connected with an articulated ball Ⅱ17. The articulated ball Ⅱ17 is articulated with the ball articulated seat 14. When the shock-absorbing bracket vibrates, the articulation mode of the articulated ball Ⅱ17 allows the shock-absorbing bracket to tilt at the hinge point, so that it can automatically adjust when facing different terrains. The inner cavity of the hydraulic cylinder Ⅱ15 forms a liquid storage cavity, and the top of the sealing piston rod Ⅱ20 is movably sleeved in the liquid storage cavity. The top of the liquid storage cavity is fixedly connected with a hose 18, and the end of the hose 18 away from the hydraulic cylinder Ⅱ15 is connected to the bottom of the nearby hydraulic cylinder Ⅰ9, and the liquid storage cavity, the hose, and the hydraulic cylinder Ⅰ9 are filled with hydraulic oil.

[0028] See also Figure 1 , Figures 3 to 5Symmetrical hinge seats 23 are fixedly connected to the side walls of the relative hydraulic cylinders Ⅱ15, and symmetrical hinge seats 23 are fixedly connected to the side walls of the two relative support rods 19. A hinge rod 24 is arranged between the two relative hinge seats 23. The two ends of the hinge rod 24 are respectively hinged to the two relative hinge seats 23. The distance between adjacent shock-absorbing brackets is limited by the hinge seats 23 and the hinge rod 24. Under normal conditions, the stability of adjacent shock-absorbing brackets is maintained. Only when vibration occurs, the shock-absorbing brackets at different positions are displaced due to the vibration, and they will be relatively displaced by means of hinges, reducing the impact on other shock-absorbing brackets, and controlling large-amplitude vibrations within a small range. The overall vibration amplitude of the entire transfer bed is smaller.

[0029] See also Figure 1 The outer wall of the bed frame 1 is bolted with evenly distributed handles 8, and medical staff can control the movement of the transfer bed through the handles 8. Different types of protective plates and brackets can be connected to the outer wall of the bed frame 1 according to needs, and the bottom end of the support rod 19 is fixedly connected to a universal wheel 22.

[0030] Embodiment 2

[0031] See also Figure 2 On the basis of the first embodiment, sliding cavities 4 are provided in the four sides of the top of the bed frame 1. The sliding cavities 4 on the long sides of the bed frame 1 are in the same direction as the long sides, and the sliding cavities 4 on the wide sides of the bed frame 1 are in the same direction as the wide sides, so that when the transfer bed is moving, no matter which direction the inclined ground is facing, the sliding cavity 4 will follow the bed frame 1 to tilt synchronously in the inclined direction, and the center of the sliding cavity 4 is fixedly connected to a partition layer 5, and both ends of the partition layer 5 are fixedly connected to a counterweight spring 7, and the end of the counterweight spring 7 away from the partition layer 5 is fixedly connected to a counterweight block 6, and the counterweight block 6 is slidably sleeved in the sliding cavity 4. When the transfer bed moves to the inclined ramp, the bed frame 1 will tilt along the inclined ramp. At this time, the counterweight block 6 will slide in the downward inclined direction. The greater the inclination angle, the farther the counterweight block 6 slides in the downward inclined direction, so that Because the bed frame 1 is tilted and in the lower position, it is heavier, which will squeeze the hydraulic cylinder Ⅱ15 below the bed frame 1 downward, so that the hydraulic cylinder Ⅱ15 squeezes the connected shock-absorbing spring 21 downward, so that the sealing piston rod Ⅱ20 here moves upward relatively, and the hydraulic oil in the hydraulic cylinder Ⅱ15 is input into the connected hydraulic cylinder Ⅰ9 through the connected hose 18, pushing the sealing piston rod Ⅰ10 to lift up, driving the bed board 13 to lift up, so that the bed board 13 remains in a relatively horizontal state, improving the safety of the patient when facing the inclined ramp, and the same is true when tipping over. When tipping over occurs, the bed board 13 is automatically adjusted so that the bed board 13 tilts more slowly relative to the tipping bed frame 1. When the medical staff adjusts the bed frame 1 that is about to tip over, the patient can still be in a relatively horizontal state, thereby improving safety.
