Description

Technical Field

[0001] This invention relates to the field of mounting technology, specifically to a mounting bracket for medical equipment used in helicopter rescue. Background Technology

[0002] Fixed supports are used to restrict the displacement of pipes or equipment; they are one type of support, while other types include sliding supports, hangers, etc. Current rescue operations often utilize helicopters for search and rescue. During helicopter search and rescue, doctors typically use stretchers to place injured personnel on the helicopter. However, within the confined space of a helicopter, it is crucial to properly install and place medical equipment such as ventilators, defibrillators, monitors, and oxygen cylinders. These medical devices are usually bolted to the aircraft, making it difficult to add or remove them. Furthermore, medical catheters are often used, secured in one area with bandages, resulting in poor control and adjustability, thus creating a poor operating environment for the catheters and equipment. Additionally, the stretcher is fixed to the aircraft cabin via a quick-release mechanism; due to the inevitable vibrations during helicopter operation, the stretcher relying solely on this mechanism can resonate, causing discomfort to the patient. To improve the operating conditions of medical equipment, we propose a medical equipment fixing frame for helicopter rescue. Summary of the Invention

[0003] The purpose of this invention is to provide a medical equipment mounting bracket for helicopter rescue, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a medical equipment mounting frame for helicopter rescue, comprising a frame plate, on which multiple guide rails are fixedly mounted, two adjacent guide rails forming a group, and a stretcher bed is slidably connected to each group of guide rails. Slider blocks are fixedly connected to both ends of each stretcher bed, and a guide wheel is fixedly connected to one side of each slider. A guide ring acting on the guide rail is provided inside each slider, with the top of the guide ring extending into the slider. A second wedge block is fixedly connected to the top of the guide ring, and a top cylinder is movably connected to the side of the guide ring. A first wedge block is fixedly connected to the end of the top cylinder near the second wedge block, and the first and second wedge blocks slide together. Multiple sliding sleeves are movably connected to the center of the bottom of each stretcher bed, and a counterweight ball is oscillatingly connected to the bottom of each sliding sleeve.

[0005] Preferably, a connecting rod is connected to the same side of the multiple sliding sleeves, and a connecting cylinder is fixedly connected to both ends of the sliding sleeves located at the head and tail of the stretcher bed. A second spring is fixedly connected between each connecting cylinder and the top cylinder.

[0006] Preferably, a load-bearing cavity is formed between the second wedge and the guide ring inside the slider, and multiple rolling balls are movably connected to each guide ring.

[0007] Preferably, a seating area is provided on both sides of the top of the frame plate, and a ventilator is fixedly connected to both ends of one side of the frame plate.

[0008] Preferably, each frame plate is fixedly connected to a connecting frame near each ventilator, the top of the connecting frame is fixedly connected to a top plate, hooks are fixedly connected to both sides of the bottom of one end of the top plate, and reinforcing ribs are fixedly connected to both sides of the bottom of each connecting frame.

[0009] Preferably, a rotating rod is fixedly connected to one side of the top plate, and a rotating plate is rotatably connected to the rotating rod. Multiple guide slots are equidistantly provided on the rotating plate, and a movable rod is slidably connected to each guide slot. Multiple take-up and put-down trays are slidably connected to each movable rod. The bottom of the rotating rod extends to the frame plate, and a bearing is fixedly connected to the bottom of the frame plate.

[0010] Preferably, each of the connecting frames is sequentially fixedly connected with a second mounting plate and a first mounting plate from bottom to top, and side plates are fixedly connected to both sides of the connecting frame. Each side plate is located above the side of the first mounting plate, and a glove box is fixedly connected to the bottom of the connecting frame.

[0011] Preferably, a base plate is fixedly connected to the bottom of the rear part of the connecting frame, and a reverse slot is fixedly connected to the top of the rear part of the connecting frame. Connecting rods are fixedly connected to both ends of one side of the first mounting plate. The connecting rods pass through the connecting frame and extend to the public area. A first spring is sleeved on each connecting rod. A second slot is fixedly connected between two first springs. The second mounting plate is fixedly connected to the base plate at both ends of one side. A first slot is slidably connected above the base plate.

[0012] Preferably, each stretcher bed has a fixedly connected rod at one end, a rack at one end, and a connecting frame with multiple gears for transmission rotatably connected near the glove box and on the rotating rod. Two gears near the glove box mesh with each other for transmission. A belt is sleeved between the bottom of the gear away from the rack and the rotating rod. A fixing pin is detachably connected to the connecting frame, and the fixing pin meshes with the rack.

[0013] Preferably, a retaining seat is provided between the connecting frame and the guide rail. The retaining seat is fixed to the frame plate. A limiting hinge is fixedly connected to one end of each retaining seat. An alignment rod is fixedly connected to one side of one of the sliders. The alignment rod and the limiting hinge are slidably connected.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] During the tilting process of the frame plate, the counterweight balls on multiple sliding sleeves located at the bottom center of the stretcher bed are biased towards the tilted side. Therefore, during the tilting process, the counterweight balls can drive the connecting cylinder to slide at the bottom of the stretcher bed, thereby causing the connecting cylinder to compress the second spring, which in turn generates a thrust to press the top cylinder. When the top cylinder generates pressure, one end of the top cylinder moves inward into the slider, thereby causing the first wedge block connected to the end of the top cylinder to press the second wedge block to descend. During the descent of the second wedge block, the second wedge block can cause the rolling ball to rotate along the axial direction of the guide roller, thereby increasing the height of the slider from the guide roller. This makes the inclined slider and the slider on the other side of the stretcher bed close to the same height, so that the stretcher bed is close to keeping horizontal with the ground, reducing the possibility of contact between the patient's side and the side of the stretcher bed, and improving the patient's comfort.

[0016] After the stretcher bed exits the guide rail and leaves the helicopter, the rack drives the gear to reverse, causing the belt to reverse and returning the rotating plate to its initial position. The length of the rotating plate is greater than the distance between the two side plates, allowing multiple movable rods at one end of the guide groove to pass over the side plate located near the middle of the helicopter, preventing the side plate from interfering with the reset of the movable rods.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-9This invention provides a technical solution: a medical equipment fixing frame for helicopter rescue, including a frame plate 1. Multiple guide rails 3 are fixedly installed on the frame plate 1, with two adjacent guide rails 3 forming a group. A stretcher bed 4 is slidably connected to each group of guide rails 3. Slider blocks 31 are fixedly connected to both ends of the stretcher bed 4. A guide wheel 30 is fixedly connected to one side of each slider 31. A guide ring 41 acting on the guide rail 3 is provided inside each slider 31. The top of the guide ring 41 extends into the slider 31. A second wedge block 40 is fixedly connected to the top of the guide ring 41. A top cylinder 37 is movably connected to the side of each guide ring 41. A first wedge block 39 is fixedly connected to the end of the top cylinder 37 near the second wedge block 40. The first wedge block 39 and the second wedge block 40 slide together. Multiple sliding sleeves are movably connected to the center of the bottom of each stretcher bed 4. 33, each sliding sleeve 33 has a counterweight ball 34 oscillatingly connected to its bottom; multiple sliding sleeves 33 are connected to a docking rod 38 on the same side; the two ends of the sliding sleeves 33 at the head and tail of the stretcher bed 4 are fixedly connected to a connecting cylinder 35; a second spring 36 is fixedly connected between each connecting cylinder 35 and the top cylinder 37; a load-bearing cavity 43 is formed inside the slider 31 between the second wedge block 40 and the guide ring 41; multiple rolling balls 42 are movably connected to each guide ring 41; when a helicopter is taking off, the vibration generated is inevitable. Therefore, helicopters are different from passenger planes. The rotor of a helicopter will generate periodic vibrations when it rotates. This vibration will be transmitted to the fuselage and the cabin. The vibration frequency of a helicopter is much higher than that of a passenger plane. Therefore, under this situation, the following improvements are made to the fixation of the stretcher bed 4 to improve the patient's experience.

[0029] After the stretcher bed 4 is installed on the guide rail 3, the ball bearing 42 located at the bottom of the slider 31 contacts the guide rail 3. The ball bearing 42 and the guide ring 41 are in a rolling connection. The ball bearing 42 rolls on the guide ring 41, reducing the friction between the guide ring 41 and the guide rail 3. The load-bearing cavity 43 can be equipped with damping and shock-absorbing cotton-like material. During the flight of the helicopter, the vibration generated is absorbed by the load-bearing cavity 43. When the helicopter turns in the air, the helicopter rotor turns, causing the entire fuselage to tilt. Therefore, the patient's side body comes into direct contact with the stretcher bed 4, which can easily cause secondary injury. In contrast, when the frame plate 1 tilts, the counterweight ball 34 on the multiple sliding sleeves 33 at the bottom center of the stretcher bed 4 is biased to one side of the tilt. Therefore, when the counterweight ball 34 tilts, During the tilting process, the connecting cylinder 35 can slide at the bottom of the stretcher bed 4, thereby compressing the second spring 36 and causing the second spring 36 to push against the top cylinder 37. When the top cylinder 37 generates pressure, one end of the top cylinder 37 moves into the slider 31, thereby causing the first wedge 39 connected to the end of the top cylinder 37 to press the second wedge 40 to descend. During the descent of the second wedge 40, the second wedge 40 can cause the ball 42 to rotate along the guide roller axis, thereby increasing the height of the slider 31 from the guide roller. This makes the inclined slider 31 and the slider 31 on the other side of the stretcher bed 4 nearly at the same height, so that the stretcher bed 4 is close to being level with the ground, reducing the possibility of contact between the patient's side and the side of the stretcher bed 4, and improving the patient's comfort.

[0030] In addition, three-point or five-point safety belts can be appropriately selected for the four sides of the stretcher bed, which can further reduce the risks to the patient.

[0031] The frame plate 1 has a seating area 2 on both sides of the top. The frame plate 1 has a ventilator 5 fixedly connected to both ends of one side. The frame plate 1 has a connecting frame 6 fixedly connected to each ventilator 5. The top of the connecting frame 6 is fixedly connected to a top plate 8. The bottom of one end of the top plate 8 is fixedly connected to both sides of the bottom of each connecting frame 6. The bottom of each connecting frame 6 is fixedly connected to a reinforcing rib 16. The hooks 9 are used to suspend the IV drip.

[0032] First, the frame panel 1 is installed near the tail section of the helicopter. The helicopter has a door that opens towards the tail section, allowing personnel to enter from the rear. The frame panel 1 tilts downwards towards the tail section to facilitate the transport of the stretcher bed 4. The interior of the helicopter is divided by two connecting frames 6, each of which is fixed to the frame panel 1 with bolts. After fixing, two areas are formed: one area is used only for medical care and emergency care, and the other area is the pilot's area and personnel movement area. The two spaces do not interfere with each other, which is conducive to the management of relevant medical personnel. Personnel can move between the two connecting frames 6. The seating areas 2 on both sides of the frame panel 1 are in contact with the inner wall of the helicopter. Generally, the frame panel 1 is connected and fixed to the interior of the helicopter with expansion bolts. The side wings of the frame panel 1 can be equipped with reinforcing structures such as reinforcing ribs. The frame panel 1 is made of a thin material, such as plastic, and the surface can be treated with an anti-slip coating.

[0033] A rotating rod 20 is fixedly connected to one side of the top plate 8. A rotating plate 10 is rotatably connected to the rotating rod 20. Multiple guide slots 11 are equidistantly opened on the rotating plate 10. A movable rod 12 is slidably connected to each guide slot 11. Multiple take-up and release trays 13 are slidably connected to each movable rod 12. The bottom of the rotating rod 20 extends to the frame plate 1. A bearing 18 is fixedly connected to the bottom of the frame plate 1.

[0034] Each connecting frame 6 is fixedly connected to a second mounting plate 15 and a first mounting plate 14 from bottom to top. Side plates 7 are fixedly connected to both sides of the connecting frame 6. Each side plate 7 is located above the side of the first mounting plate 14. A glove box 17 is fixedly connected to the bottom of the connecting frame 6.

[0035] A base plate 21 is fixedly connected to the bottom of the rear of the connecting frame 6, and a reverse slot 24 is fixedly connected to the top of the rear of the connecting frame 6. A connecting rod 26 is fixedly connected to both ends of one side of the first mounting plate 14. The connecting rod 26 passes through the connecting frame 6 and extends to the public area. A first spring 25 is sleeved on each connecting rod 26. A second slot 23 is fixedly connected between two first springs 25. A base plate 21 is fixedly connected to both ends of one side of the second mounting plate 15. A first slot 22 is slidably connected above the base plate 21.

[0036] Furthermore, a ventilator base is installed inside the ventilator station 5, and two oxygen cylinders are installed on the back of each connecting frame 6 for backup. The ventilator display device can be placed on the second mounting plate 15, while the pulse oximeter and defibrillator can be placed on the first mounting plate 14. The tubing connections of the above devices can be attached to each take-up tray 13, which is slidably connected to the movable rod 12 using a sliding locking method to organize the tubing of each device and adjust their relative positions to ensure optimal device performance without interference between tubing, reducing the difficulty of temporary care. The side plate 7 has multiple openings (not shown), allowing the side plate 7 to not interfere with the tubing of related devices when the movable plate is retracted. When the movable plate is retracted, it covers the front of the two side plates 7 to prevent the pulse oximeter and defibrillator from falling onto the frame plate 1 due to vibration. Related devices can be freely added to the first mounting plate 14. The glove box 17 can hold an AED and related auxiliary equipment, as well as miscellaneous items and disinfection supplies.

[0037] The oxygen cylinder can be placed on the base plate 21, with the top outer ring of the oxygen cylinder resting against the reverse slot 24. Then, quick-release screws are used to fix the first slot 22 and the second slot 23 respectively, locking the bottom and middle of the oxygen cylinder to prevent the oxygen cylinder from becoming loose and causing danger.

[0038] Each stretcher bed 4 has a fixed connection to a shovel rod 401 at one end, and a rack 29 is fixedly connected to one end of the shovel rod 401. The connecting frame 6 has multiple gears 19 for transmission that are rotatably connected near the glove box 17 and on the rotating rod 20. The two gears 19 located near the glove box 17 mesh with each other for transmission. A belt is sleeved between the bottom of the gear 19 away from the rack 29 and the rotating rod 20. A fixing pin 28 is detachably connected to the connecting frame 6, and the fixing pin 28 and the rack 29 mesh with each other.

[0039] Furthermore, during the installation of the stretcher bed 4, the stretcher bed 4 will slide along the guide rail 3. When the stretcher bed 4 moves to one end of the guide rail 3, the push rod 401 located in the middle of the stretcher bed 4 will drive the rack 29 to contact the gear 19 located at the bottom of the connecting frame 6 and rotate. During the rotation of the gear 19, another gear 19 has an outwardly extending belt sleeved at the bottom of its shaft. This belt can continue to drive the rotating rod 20 located on one side of the bottom of the connecting frame 6 to rotate, so that the rotating rod 20 causes the rotating plate 10 to flip on one side of the connecting frame 6 during the rotation, automatically moving the rotating plate 10 into the connecting frame 6. When the stretcher bed 4 is opened, multiple movable rods 12 located on the rotating plate 10 can slide on the guide groove 11 to facilitate the adjustment of the position of the movable rods 12. Multiple take-up and take-down trays 13 located on each movable rod 12 can also slide along the movable rod 12. When the stretcher bed 4 exits the guide rail 3 and leaves the helicopter, the rack 29 drives the gear 19 to reverse, causing the belt to reverse and returning the rotating plate 10 to its initial position. The length of the rotating plate 10 is greater than the distance between the two side plates 7, allowing the multiple movable rods 12 to pass over the side plate 7 located near the middle of the helicopter at one end of the guide groove 11, preventing the side plate 7 from interfering with the reset of the movable rods 12.

[0040] Furthermore, when it is necessary to install or dismantle the stretcher bed 4, relevant medical personnel can directly pull the stretcher bed 4 out of the helicopter from the two guide rails 3. This can be done manually by pulling out the fixing pin 28, while another person pulls the stretcher bed 4 from the tail section of the helicopter. The two people work together to pull the stretcher bed 4 out. During this process, the external teeth of the fixing pin 28 and the rack 29 separate, allowing the stretcher bed 4 to be pulled out as a single unit with the push rod 401. This is very simple and convenient to operate. After the stretcher bed 4 has transported a patient, when returning to the helicopter, it can be manually moved again. The slider 31 is placed on the guide rail 3, and then the stretcher bed 4 is slid on the guide rail 3 manually so that the alignment rod 32 passes through the limiting hinge 2701 and the bottom of the stretcher bed 4 contacts the card seat 27. In this state, the stretcher bed 4 can be fixed inside the helicopter. At this time, the stretcher bed 4 can be locked by manually removing the fixing pin 28 again. The fixing pin 28 and the frame plate 1 are connected and fixed together by a sliding locking method. The fixing pin 28 and the rack 29 are both rounded so that when the stretcher bed 4 is subjected to vibration, the fixing pin 28 does not affect the axial movement of the stretcher bed 4 towards the push rod 401.

[0041] A card seat 27 is provided between the connecting frame 6 and the guide rail 3. The card seat 27 is fixed on the frame plate 1. A limit hinge 2701 is fixedly connected to one end of each card seat 27. One of the sliders 31 is fixedly connected to one side of the alignment rod 32. The alignment rod 32 and the limit hinge 2701 are slidably connected to assist manual observation of whether the stretcher bed 4 has reached the installation position.
