Description

Technical Field

[0001] The present invention relates to the technical field of medical vehicles, in particular to a telescopic medical vehicle for field nursing. Background Art

[0002] A medical vehicle is a motor vehicle used for medical examinations and medical treatments. It is equipped with relevant medical equipment and professional nurses and doctors. Injured people may appear at any time during combat on the battlefield. Therefore, in the First World War, shortly after the advent of cars, cars were used for medical rescue. For field combat, field medical vehicles are usually used to quickly transport, care for, and provide basic medical treatment to the wounded.

[0003] In the prior art, for field operations, due to the rugged field roads, the stretcher carts equipped on medical vehicles are inconvenient to use, so transport stretchers are mostly used. However, during field operations, for the transportation and care of the wounded, the stretcher based on the medical vehicle has the following defects: when the wounded are transported to the medical vehicle, manpower is required to move the stretcher and the wounded onto the vehicle, resulting in easy bumps and shakes during the transportation process, causing secondary injuries to the wounded, and is time-consuming and labor-intensive. At the same time, the existing stretcher usually adopts corresponding connecting buckles to connect with the medical vehicle, but during the medical vehicle transporting the wounded, due to the rugged field roads, the vehicle is prone to shake. The stretcher is fixedly connected to the medical vehicle, so that the bumps are obviously transmitted, making the wounded prone to accidental bumps and displacements on the stretcher, which is easy to cause secondary injuries and discomfort to the wounded.

[0004] In view of this, the present invention proposes a telescopic medical vehicle for field nursing to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0008] body;

[0009] A support frame is arranged in the vehicle body, and a stretcher is arranged on the support frame;

[0010] The anti-bumping component is arranged under the stretcher and includes a water box and a float box arranged under the stretcher. Two movable float plates are arranged inside the float box. A group of float strips are embedded at the bottom of the float plates. Both sides of the bottom of the float strips are set with rounded corners, and through holes are opened inside the float strips.

[0011] In a preferred embodiment, the anti-bumping assembly further comprises four support rods, four sleeves are installed inside the water box, one end of the support rod penetrates into and extends into the interior of the sleeve, the other end of the support rod is hinged to the bottom of the stretcher through a ball bearing, and a floating ball and a floating plate in the sleeve are fixedly mounted on the outer side of the support rod, and a group of damping holes are opened inside the floating plate.

[0012] In a preferred embodiment, the stretcher is provided with eight airbag cushions mounted on the top, two frame-shaped tubes are sleeved on the outside of the stretcher, and four cross tubes are provided on opposite sides of the two frame-shaped tubes, and the airbag cushions are connected to the frame-shaped tubes through the cross tubes.

[0013] In a preferred embodiment, an air pump and a gyroscope sensor are respectively installed at the bottom of the stretcher, and a three-way pipe is installed at the output end of the air pump, and both ends of the three-way pipe are respectively connected to two frame-shaped pipes.

[0014] In a preferred embodiment, a support tube is installed between the float box and the stretcher, an air guide hole is provided between the float box and the support tube, an inclined tube for communication is provided between the three-way tube and the support tube, and a piston plate is slidably connected to the inside of the support tube.

[0015] In a preferred embodiment, first springs are installed on the tops of the piston plate and the floating bars. The first spring on the floating bars is installed inside the floating plate and is in a compressed state. The first spring on the piston plate is installed inside the support tube.

[0016] In a preferred embodiment, two hydraulic rods are installed on the inner top wall of the vehicle body, a rope box is installed at one end of the hydraulic rod, a servo motor is installed on one side of the rope box, the output shaft of the servo motor is installed with a rope roller through a coupling, two traction ropes extending to the outside of the rope box are wound around the rope roller, a hook is installed at one end of the traction rope, two hanging rings matching the hooks are installed on both sides of the stretcher, and the outer side of the hanging ring is provided with a handle fixed to the outside of the stretcher.

[0017] In a preferred embodiment, a frame-shaped box is provided at the bottom of the stretcher, four cavities are opened inside the stretcher, a counterweight block is slidably connected to the inside of the cavity, a second spring is installed between the counterweight block and the cavity, a vertical pipe for communication is installed between the cavity and the frame-shaped box, and a folded pipe for communication is provided between the tee pipe and the vertical pipe.

[0018] In a preferred embodiment, exhaust pipes are installed on the outsides of the frame-shaped tube, the folded tube and the inclined tube, and solenoid valves are installed on the outsides of the horizontal tube, the vertical tube, the inclined tube and the exhaust pipe.

[0019] In a preferred embodiment, a well-shaped wave-breaking plate is installed inside the water box, and a water flow channel is provided between the well-shaped wave-breaking plate, the sleeve and the inner bottom wall of the water box.

[0020] Compared with the prior art, the present invention provides a telescopic medical vehicle for field nursing, which has the following beneficial effects:

[0021] 1. By using the salt water in the water box with the float box, float plate, float ball and float plate, the buoyancy is used to support the stretcher. When a bumpy situation occurs, the float plate will move with the bumpy situation. At this time, the damping hole inside it can resist the bump by limiting the flow speed of the water flow, thereby achieving a buffering effect. When the vehicle shakes and generates inertia, the water flow in the water box will move according to the direction of the shaking inertia. At this time, the float plate will deviate accordingly in the direction of inertia, thereby causing the stretcher to tilt slightly, and use its tilted state to offset part of the inertia. At this time, the airbag cushion in the inertial direction will be replenished with air in time to reduce the displacement of the injured. At the same time, the counterweight block in the stretcher will adjust the center of gravity in time according to the shaking and tilting conditions, and assist the stretcher to be quickly leveled with the float plate to reduce the impact of shaking and bumping on the injured. At the same time, throughout the process, multi-zone airbag cushions are used to provide soft support for the patient to reduce the occurrence of secondary injuries to the injured. According to the ruggedness of the road and the needs of the injured in rescue, the float plate can be adjusted outward to change the buoyancy of the stretcher and at the same time achieve the effect of fixing and locking the stretcher.

[0022] 2. Using a hydraulic rod and a servo motor-driven traction rope, the hook on the traction rope can be connected to the scraper ring on the stretcher, allowing the stretcher to be telescopically raised and lowered to the outside of the vehicle to receive the injured person. The injured person can then be transported into the vehicle by lifting and retracting. The traction rope can be adjusted to meet different transport needs based on road conditions and the vehicle's parking angle, changing the stretcher's receiving angle to meet different transport needs. This reduces manual handling time, ensures stable transport, and reduces accidental bumps and shaking, thereby reducing the risk of secondary injuries to the injured during transport. This solves the problem of existing stretchers being easily bumped and shaken when manually transporting the injured onto the vehicle, and the bumps and shakes during the travel of the medical vehicle, which can easily cause secondary injuries to the injured.

[0047] The following combination Figures 1 to 10 The telescopic medical vehicle for field care of the present invention is described.

[0048] Example 1:

[0049] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in one embodiment, a telescopic medical vehicle for field care includes a vehicle body 100 and a support frame 200 installed therein, with a stretcher 300 provided on the support frame 200; an anti-bumping assembly 400, which is arranged below the stretcher 300 and is used to reduce the bumping effect of the vehicle body 100 on the stretcher 300 during travel; wherein, the anti-bumping assembly 400 includes a water box 410 and a float box 420 installed below the stretcher 300, wherein two movable float plates 421 are provided inside the float box 420, and a group of float bars 422 are embedded at the bottom of the float plates 421, both sides of the bottom of the float bars 422 are set to rounded corners, and a through hole 427 is opened inside the float bars 422.

[0050] like Figure 5 and Figure 7 As shown, the anti-bumping assembly 400 also includes four support rods 430, four sleeves 411 are installed inside the water box 410, one end of the support rod 430 penetrates and extends into the interior of the sleeve 411, and the other end of the support rod 430 is hinged to the bottom of the stretcher 300 through a ball bearing, and the outer side of the support rod 430 is fixedly provided with a floating ball 431 and a floating plate 432 in the sleeve 411, and a group of damping holes are opened inside the floating plate 432.

[0051] It should be noted that when this embodiment is in use, a preset amount of saline can be pre-introduced into the water box 410, and the support rod 430 can be extended to the inside of the sleeve 411. At this time, the float box 420 is in contact with the water surface, and the float ball 431 and the float plate 432 are also placed in the water source. At this time, the stretcher 300 is placed in a limited position, and during driving in the field area, the vehicle body 100 will experience corresponding bumps.

[0052] During small-amplitude bumps, the damping holes on the float plate 432 are used to limit the water flow rate, thereby reducing the movement amplitude of the float box 420 and the float ball 431 driven by the shaking of the water source, thereby buffering the bumps.

[0053] When the road is severely rugged, the float plate 421 in the float box 420 can be moved outward, and the float strips 422 inside it can be used to contact the salt water to increase the buoyancy of the stretcher 300. During large-scale bumps, the provision of the through holes 427 helps to adjust the pressure difference between the upper and lower surfaces of the float strips 422, so that the buoyancy response of the float strips 422 is faster, thereby more effectively cushioning the bumps of the stretcher 300. Combined with the provision of rounded corners on both sides, the separation of salt water is reduced, thereby reducing the generation of turbulence, that is, reducing the generation of water waves and the occurrence of excessive bumps. At the same time, during the storage process of the float strips 422, the rounded corners can be used to contact the corners of the float box 420, so that the float strips 422 can be squeezed into the interior of the float plate 421 for storage and guidance.

[0054] When the vehicle body 100 tilts and shakes during driving, the water flow in the water box 410 will move according to the inertial direction of the shaking. At this time, the float box 420 will deviate accordingly to follow the inertial direction, thereby causing the stretcher 300 to tilt slightly, using its tilted state to offset part of the inertia.

[0055] At this time, the airbag cushion 310 in the inertial direction is replenished with air in time, and the support height in the inertial direction is slightly raised to reduce the displacement of the injured person. At the same time, the counterweight block 370 in the stretcher 300 will adjust the center of gravity in time according to the shaking and tilting conditions, and assist the stretcher 300 with the float plate 421 to quickly level it, reducing the impact of shaking and bumping on the injured person.

[0056] During the whole process, the buoyancy of the stretcher 300 is increased by utilizing the outward expansion width of the floating plate 421 in the float box 420, so as to adapt to different degrees of rugged roads. When the wounded need to be treated urgently or fixed, the floating plate 421 in the float box 420 can be continuously expanded outward until its outer side contacts and fits with the inner wall of the water box 410 to reach a stuck state. At this time, the friction between the floating plate 421 and the water box 410 is utilized to ensure the stability of the stretcher 300, which is convenient for subsequent operations. In special circumstances, such as Figure 5As shown, the valve on the water box 410 can also be opened to discharge the brine along the corresponding pipe provided thereon, so that the bottom end of the support rod 430 contacts the bottom wall of the water box 410 to ensure stability;

[0057] It should be noted that the user can set anti-slip grooves and rubber protective pads on the outer side of the floating plate 421 according to usage conditions.

[0058] Example 2:

[0059] Based on the telescopic medical vehicle for field nursing described in Example 1, Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the stretcher 300 is provided with eight airbag cushions 310 installed on the top, and two frame-shaped tubes 320 are provided on the outside of the stretcher 300. Four cross tubes 321 are provided on the opposite sides of the two frame-shaped tubes 320. The airbag cushions 310 are connected to the frame-shaped tubes 320 through the cross tubes 321.

[0060] It should be noted that, in this embodiment, according to the condition of the injured person, when the stretcher 300 is selected to provide rigid support for the injured person, the gas in the airbag cushion 310 can be discharged along the transverse tube 321;

[0061] However, when soft support is required for the injured person, the corresponding gas can be introduced into the corresponding airbag cushion 310 along the transverse tube 321 on the frame tube 320 to provide soft support for different areas of the injured person's body;

[0062] Furthermore, the support heights of the eight airbag cushions 310 can be adjusted accordingly according to the condition of the injured person.

[0063] In a preferred embodiment, Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, an air pump 330 and a gyroscope sensor 500 are respectively installed at the bottom of the stretcher 300 , and a three-way pipe 331 is installed at the output end of the air pump 330 , and both ends of the three-way pipe 331 are respectively connected to the two frame-shaped pipes 320 .

[0064] It should be noted that, in this embodiment, the setting of the gyroscope sensor 500 is adopted to facilitate real-time monitoring of the tilt of the stretcher 300. When the stretcher 300 tilts, the air pump 330 is driven to extract the corresponding amount of gas based on the data monitored by the gyroscope sensor 500, so that the corresponding counterweight block 370 moves and the corresponding airbag cushion 310 is replenished with air to support it, thereby resisting the tilt inertia and assisting the stretcher 300 to be leveled quickly, reducing excessive shaking and accidental bumps on the injured person, and reducing the occurrence of secondary injuries.

[0065] In a preferred embodiment, Figure 5 、 Figure 6 and Figure 7 As shown, a support tube 423 is installed between the float box 420 and the stretcher 300, an air guide hole is set between the float box 420 and the support tube 423, an inclined tube 424 for communication is set between the three-way pipe 331 and the support tube 423, and a piston plate 425 is slidably connected inside the support tube 423.

[0066] It should be noted that in this embodiment, by utilizing the setting of the inclined tube 424, the gas in the three-way tube 331 can be introduced into the support tube 423 along the inclined tube 424, and then the gas enters the float box 420 along the air guide hole, and the float plate 421 is driven to move by gas extrusion.

[0067] In a preferred embodiment, Figure 6 and Figure 9 As shown, first springs 426 are installed on the top of the piston plate 425 and the floating bar 422. The first spring 426 on the floating bar 422 is installed inside the floating plate 421 and is in a compressed state. The first spring 426 on the piston plate 425 is installed inside the support tube 423.

[0068] It should be noted that, in this embodiment, when the float plate 421 moves to the outside of the float box 420, the first spring 426 on its top will push the float bar 422 to move downward, so that the bottom of the float bar 422 contacts the salt water to perform buoyancy adjustment operations. The setting of the first spring 426 on the piston plate 425 can be used to pull the piston plate 425 to reset when the float bar 422 needs to be stored, so that the gas in the float box 420 is extracted, that is, drive the two float plates 421 to move and reset under the influence of negative pressure.

[0069] Example 3:

[0070] Based on the telescopic medical vehicle for field nursing described in Example 1, Figure 3 and Figure 4 As shown, two hydraulic rods 110 are installed on the inner top wall of the vehicle body 100, and a rope box is installed at one end of the hydraulic rod 110. A servo motor 120 is installed on one side of the rope box. The output shaft of the servo motor 120 is installed with a rope roller through a coupling. Two traction ropes 130 extending to the outside of the rope box are wound around the rope roller. A hook is installed at one end of the traction rope 130. Two hanging rings matching the hooks are installed on both sides of the stretcher 300, and the outer side of the hanging ring is provided with a handle fixed to the outside of the stretcher 300.

[0071] It should be noted that, in this embodiment, a hook is pre-connected with a teammate scraper ring on the stretcher 300. After the vehicle body 100 is parked, the servo motor 120 is pre-started, the stretcher 300 is hoisted using the traction rope 130, and the hydraulic rod 110 is started to move the rope box together with the servo motor 120 to the outside of the vehicle body 100. Then, the servo motor 120 drives the stretcher 300 to descend to a suitable position, and then the patient is moved onto the stretcher 300. The above operation is repeated to transfer the patient into the vehicle body 100.

[0072] If the road conditions in the field area are poor, after the vehicle body 100 is parked, the corresponding servo motor 120 can adjust the retraction and extension of the traction rope 130 according to the parking tilt angle, so that the stretcher 300 is tilted accordingly, thereby ensuring the horizontality with the injured during the transportation process;

[0073] In special circumstances, the stretcher 300 can also be carried manually by holding the corresponding handles.

[0074] In a preferred embodiment, Figure 5 、 Figure 7 and Figure 8 As shown, a frame box 340 is provided at the bottom of the stretcher 300, and four cavities are opened inside the stretcher 300. A counterweight block 370 is slidably connected inside the cavity, and a second spring 380 is installed between the counterweight block 370 and the cavity. A vertical pipe 350 for communication is installed between the cavity and the frame box 340, and a folded pipe 360 ​​for communication is provided between the three-way pipe 331 and the vertical pipe 350.

[0075] It should be noted that, in this embodiment, after the stretcher 300 tilts and shakes, the gyroscope sensor 500 will detect the tilt, and then start the air pump 330 to introduce the corresponding gas into the corresponding cavity, so that the corresponding single or two counterweights 370 move to the corresponding position, and use gravity control to change the center of gravity, thereby resisting the shaking of the stretcher 300; for example, when the counterweight 370 is driven, the air pump 330 is started, and the solenoid valve 700 on the vertical pipe 350 is opened at this time, and the gas is introduced into the corresponding cavity to complete the driving of the counterweight 370. When the solenoid valve 700 on the horizontal pipe 321 is opened, the gas can be introduced into the corresponding airbag cushion 310 to complete the adjustment of the support height. When the solenoid valve 700 on the inclined pipe 424 is opened, the gas can be introduced into the support pipe 423 to complete the expansion adjustment of the float 421.

[0076] After the counterweight 370 and the floating plate 421 are used, the second spring 380 can be used to pull the counterweight 370 and the piston plate 425 to reset. After the piston plate 425 is pulled to reset, the floating plate 421 is also reset.

[0077] In a preferred embodiment, Figure 4、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the outer sides of the frame tube 320 , the folded tube 360 ​​and the oblique tube 424 are all installed with exhaust pipes 600 , and the outer sides of the horizontal tube 321 , the vertical tube 350 , the oblique tube 424 and the exhaust pipe 600 are all installed with solenoid valves 700 .

[0078] It should be noted that when the airbag cushion 310, the counterweight block 370 and the float plate 421 need to be reset, the corresponding solenoid valves 700 on the frame tube 320, the folded tube 360 ​​and the inclined tube 424 can be opened to allow the gas to be discharged along the corresponding exhaust pipe 600. Combined with the setting of the remaining solenoid valves 700, the opening and closing of the horizontal tube 321, the vertical tube 350 and the inclined tube 424 can be intelligently controlled, which is more convenient.

[0079] In a preferred embodiment, Figure 5 and Figure 10 As shown, a well-shaped wave-breaking plate 412 is installed inside the water box 410 , and a water flow channel is provided between the well-shaped wave-breaking plate 412 , the sleeve 411 and the inner bottom wall of the water box 410 .

[0080] It should be noted that the use of the well-shaped wave-breaking plate 412 can reduce the water flow generated by the water box 410, thereby reducing the occurrence of bumps and shaking. This can allow salt water to normally enter the interior of the casing 411, ensure the use in combination with the float 432 and the float ball 431, and allow the water source at the bottom of the well-shaped wave-breaking plate 412 to circulate normally.

[0081] The working principle of the telescopic medical vehicle for field nursing of the present invention is as follows:

[0082] A hook is used to pre-connect with the teammate scraper ring on the stretcher 300. After the vehicle body 100 is parked, the servo motor 120 is pre-started, the stretcher 300 is lifted by the traction rope 130, and the hydraulic rod 110 is started to move the rope box together with the servo motor 120 to the outside of the vehicle body 100. Then, the servo motor 120 drives the stretcher 300 to descend to a suitable position, and then the patient is moved onto the stretcher 300. The above operation is repeated to transfer the patient into the vehicle body 100. If the road in the field area is not good, after the vehicle body 100 is parked, the corresponding servo motor 120 can adjust the retraction and extension of the traction rope 130 according to the parking tilt angle, so that the stretcher 300 is tilted accordingly, thereby ensuring the horizontality with the injured during the transfer process;

[0083] A preset amount of saline is introduced into the water box 410 in advance, and the support rod 430 is extended into the interior of the sleeve 411. At this time, the float box 420 is in contact with the water surface, and the float ball 431 and the float plate 432 are also placed in the water source. At this time, the limited placement of the stretcher 300 is completed. During the driving process in the field area, the vehicle body 100 will experience corresponding bumps; during the small-amplitude bumps, the damping hole on the float plate 432 is used to limit the flow speed of the water flow, thereby reducing the movement amplitude of the float box 420 and the float ball 431 driven by the shaking of the water source. Buffering the bumps; when the road is seriously rugged, the float plate 421 in the float box 420 can be moved outward, and the float strips 422 inside it can be used to contact the salt water to increase the buoyancy of the stretcher 300. During the large-scale bumps, the setting of the through holes 427 helps to adjust the pressure difference between the upper and lower surfaces of the float strips 422, so that the buoyancy response of the float strips 422 is faster, thereby more effectively buffering the bumps of the stretcher 300. The setting of the rounded corners on both sides can reduce the separation of salt water, thereby reducing The turbulence is reduced, that is, the generation of water waves is reduced and the occurrence of excessive bumps is reduced. When the vehicle body 100 tilts and shakes during driving, the water flow in the water box 410 will move according to the inertial direction of the shaking. At this time, the float box 420 will follow the inertial direction and make a corresponding offset, so that the stretcher 300 is slightly tilted, and its tilting state is used to offset part of the inertia. At this time, the airbag cushion 310 in the inertial direction is timely inflated, and the support height in the inertial direction is slightly raised to reduce the displacement of the injured. At the same time, the counterweight block 370 in the stretcher 300 will adjust the center of gravity in time according to the shaking and tilting conditions, and assist the stretcher 300 with the float plate 421 to quickly level it, reducing the impact of shaking and bumping on the injured. Buoyancy support is used. During driving, buoyancy buffering, center of gravity control and support height adjustment of the airbag cushion 310 are used to effectively respond to bumps, tilts and shaking, and assist the stretcher 300 to quickly level it, reducing accidental bumps and displacements of the injured and reducing the occurrence of secondary injuries.
