Description

Technical Field

[0001] The invention relates to the field of medical equipment, in particular to an emergency rescue device at a medical accident scene. Background Art

[0002] Modern rescue medicine is a science that deals with and studies various critical emergencies, accidental disasters and accidents that occur in the production and life outside hospitals in modern society, organizes rescue forces in a timely manner, implements timely and effective rescue and first aid to individuals or groups on the spot, and performs necessary medical treatment to save lives, reduce injuries and pain, and transports the injured and patients to hospitals under medical supervision using modern transportation for further comprehensive treatment.

[0003] In addition to the above, modern rescue medicine also covers out-of-hospital emergency care, medical and disaster monitoring and transportation, in-hospital emergency care, in-hospital critical care and treatment for various disasters and emergency events, poisoning rescue, and traffic accident rescue. For example, airport rescue medicine studies the emergency care, treatment, and nursing of personnel in aircraft emergencies inside and outside the airport, or in cases where there is no aircraft emergency. Unlike general emergency medicine, airport rescue medicine must study the rescue characteristics of emergency situations involving aircraft (out-of-air accidents, etc.) and conditions where there is no aircraft emergency (fire, earthquake, etc.). Therefore, modern rescue medicine must pay attention to disaster science issues other than medicine, such as understanding the airport emergency plan, being able to transfer from normal airport activities to emergency status in a timely, orderly, and efficient manner, and especially mastering the basic framework and content of the airport rescue plan, which includes mastering methods of survival in distress, that is, seeking a place to survive and protect it, seeking water and food to sustain life, and finding a way to survive; timely and comprehensive control of injuries and diseases, and establishing a firm hope for survival. Similarly, flood prevention also involves the issue of flood prevention and rescue medicine, which requires the integration of environmental medicine, preventive medicine, and health rescue science.

[0004] When carrying out rescue operations for traffic accidents or disasters such as earthquakes, there will be a large number of surgical patients, including fractures, major injuries, or comatose people. We need to deal with these injured people in an emergency, such as fixing the fractured bones, fixing the cervical spine, or emergency hemostasis. After the above emergency operations are completed, the injured need to be transported on a stretcher. Therefore, the importance of stretchers in the rescue process is self-evident, so further development of stretchers is very necessary. Summary of the invention

[0005] The purpose of the present invention is to provide an emergency rescue device for a medical accident scene, which can be folded and conveniently carry out emergency treatment and transportation of the wounded, thereby improving the rescue efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a medical accident scene emergency rescue device, comprising a stretcher body, wherein the stretcher body comprises a plurality of assembly units;

[0007] The assembly unit comprises a square frame, the square frame comprises two connecting edges and two side edges connected to other assembly units, the connecting edges are provided with connecting mechanisms connected to other assembly units, a connecting rod is provided inside the square frame, a cylindrical airbag is wrapped outside the square frame and the connecting rod, an air passage communicating with each other is provided inside the square frame and the connecting rod, the air passage is connected to a connecting pipe connected to the cylindrical airbag, and an air release valve and an air intake check valve are provided on the air passage;

[0008] The connecting mechanism comprises a connecting block connected to the connecting edge, a rotating cylinder is arranged in the connecting block, a ventilation cavity is arranged in the rotating cylinder, a piston cavity is arranged in the connecting block and is vertical to the rotating cylinder and horizontally arranged, the piston cavity is communicated with the air passage, a piston body is sealingly and slidingly connected in the piston cavity, the piston body is connected with a latch, the jack is located outside the rotating cylinder and in the horizontal direction, a mounting platform is arranged on the piston cavity, a compression spring is arranged between the mounting platform and the piston body, and a connecting pipe communicating with the ventilation cavity is arranged on the side of the piston cavity;

[0009] A rotating shaft is sealed and rotatably connected in the rotating cylinder, one end of the rotating shaft is connected to a support rod, and a plug hole perpendicular to the rotating shaft is arranged near the other end of the rotating shaft, the connecting pipe drives the piston body to move by gas in the piston cavity so that the plug is connected to the piston cavity after being inserted into the plug hole, a vent hole is arranged on the surface of the rotating shaft in the ventilation cavity, and an air passage connected to the vent hole is arranged in the rotating shaft and the support rod, and the air passage is connected to the air passage;

[0010] The connecting block and the support rod are provided with switch valves for opening and closing the gas flow.

[0011] Through the above technical solution, since the assembly units can be easily assembled together to form a stretcher body, the transportation and placement of the stretcher body saves more space and can meet the requirements of different heights; at the same time, a cylindrical airbag is wrapped around the square frame and the connecting rod, so that when the cylindrical airbag is in use, it has greater cushioning performance, thereby ensuring the comfort and safety of the wounded during transportation; in addition, when connecting, it is only necessary to conveniently insert the rotating shaft into the rotating cylinder, and then put it flat on the ground, and then start to fill air into the air passage. While filling the gas, due to the pressure in the cylindrical airbag, the air is compressed. The force gradually increases, so the pressure in the piston chamber also increases. After increasing to a certain extent, the air pressure pushes the piston body and the pin to move, so that the pin is inserted into the socket, thereby completing the relative connection of the two assembly units. At the same time, since the piston body no longer blocks the connecting pipe, the connecting pipe is connected to the piston chamber, and then the gas enters the ventilation chamber, and through the ventilation hole on the rotating shaft, the gas enters the air passage of the other assembly unit. The above operation is simple, and only one assembly unit needs to be ventilated; through the switch valve, the user can conveniently control the flow direction of the gas according to needs, thereby completing installation or disassembly.

[0012] Preferably, it also includes a hemostatic airbag, which is arranged in an annular shape, the elasticity of the outer surface of the hemostatic airbag is smaller than the elasticity of the inner surface, and the hemostatic airbag is connected to an inflation device, and the inflation device is connected to an air release valve.

[0013] With the above technical solution, since the elasticity of the outer surface of the hemostatic airbag is relatively small, the deformation of the inner surface becomes larger after inflation, so the volume of the hemostatic airbag extends inward, thereby compressing the wound and achieving the purpose of temporary hemostasis.

[0014] Preferably, it also includes a skeleton-fixed airbag, wherein Velcro is provided on both sides of the skeleton-fixed airbag, and the Velcro is interconnected to form a cylinder with a ring-shaped cross-section, and parallel fixed plates are provided in the skeleton-fixed airbag, and the skeleton-fixed airbag is connected to an inflation device, and the inflation device is connected to an air deflation valve.

[0015] Through the above technical solution, the skeleton fixing airbag can be conveniently installed to the required installation position through Velcro. At the same time, the position of the Velcro connection can also determine the size of the skeleton fixing airbag. At the same time, the fixing plate can play a supporting role, and the airbag can fully contact the human body, thereby being able to temporarily fix the fracture well.

[0016] Preferably, it also includes a neck fixing airbag, which includes an upper fixing part that contacts the chin and the head and a lower fixing part that contacts the shoulder, the lower fixing part is connected to a fixing tube for inserting the neck, an annular airbag is connected between the fixing tube and the upper fixing part, the neck fixing airbag is connected to an inflation device, and the inflation device is connected to an air release valve.

[0017] Through the above technical solution, since the upper fixing part is relatively fixed to the chin and the head, and the lower fixing part is relatively fixed to the neck, at this time, the annular airbag is inflated, and due to its increase in volume, pressure is exerted on the chin, head and neck at the same time, thereby generating an upward supporting force on the neck and keeping it immovable, thereby completing a good fixation of the neck.

[0018] Preferably, the inflation device comprises an inflation tube, the inflation tube is connected to an inflation one-way valve, and the inflation one-way valve is connected to the deflation valve.

[0019] Through the above technical solution, the gas in the cylindrical airbag can be used through the inflation tube to perform temporary operations during emergency treatment, so that no additional inflation device is required, and it is more suitable for on-site use.

[0020] Preferably, handles are connected to both ends of the side.

[0021] Through the above technical solution, the use and transportation of the stretcher body can be conveniently completed through the handle.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The assembly units can be easily assembled together to form a stretcher body, so the transportation and placement of the stretcher body saves space and can meet the requirements of different heights;

[0024] (2) The cylindrical airbag has greater cushioning properties, which can ensure the comfort and safety of the injured during transportation;

[0025] (3) After assembly, only one assembly unit needs to be inflated, so the operation steps are more streamlined. At the same time, the hemostatic airbag, the skeleton fixation airbag and the neck fixation airbag can better realize various emergency functions applicable to the accident scene and have a wide range of applications.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-5 , an embodiment provided by the present invention:

[0034] A medical accident scene emergency rescue device includes a stretcher body 1, and the stretcher body 1 includes a plurality of assembly units 2. Since the assembly units 2 can be easily assembled together to form the stretcher body 1, the transportation and placement of the stretcher body 1 saves more space and can meet the requirements of different heights.

[0035] The assembly unit 2 includes a square frame 3, which includes two connecting edges 4 and two side edges 5 connected to other assembly units 2. The connecting edges 4 are provided with connecting mechanisms connected to other assembly units 2. A connecting rod 6 is provided inside the square frame 3. The square frame 3 and the connecting rod 6 are wrapped with a cylindrical airbag 7. The square frame 3 and the connecting rod 6 are provided with mutually connected air passages 8. The air passage 8 is connected to a connecting pipe 9 connected to the cylindrical airbag 7. The air passage 8 is provided with a deflation valve 10 and an air intake check valve 11. The cylindrical airbag 7 is wrapped outside the square frame 3 and the connecting rod 6. Therefore, when the cylindrical airbag 7 is used, it has greater cushioning properties, thereby ensuring the comfort and safety of the wounded during transportation.

[0036] The connecting mechanism includes a connecting block 12 connected to the connecting edge 4, a rotating cylinder 13 is arranged in the connecting block 12, a ventilation chamber 14 is arranged in the rotating cylinder 13, a piston chamber 15 is arranged vertically and horizontally to the rotating cylinder 13 in the connecting block 12, the piston chamber 15 is connected to the air passage 8, a piston body 16 is sealingly and slidingly connected in the piston chamber 15, the piston body 16 is connected to the pin 17, the socket 23 is located outside the rotating cylinder 13 and in the horizontal direction, a mounting platform 18 is arranged on the piston chamber 15, a compression spring 19 is arranged between the mounting platform 18 and the piston body 16, and a connecting pipe 20 connected to the ventilation chamber 14 is arranged on the side of the piston chamber 15.

[0037] A rotating shaft 21 is sealed and rotatably connected inside the rotating cylinder 13, one end of the rotating shaft 21 is connected to a support rod 22, and the other end of the rotating shaft 21 is provided with a socket 23 perpendicular to the rotating shaft 21 near the end, and the connecting pipe 20 drives the piston body 16 to move in the piston chamber 15 so that the pin 17 is inserted into the socket 23 and then communicates with the piston chamber 15, and a vent hole 24 is provided on the surface of the rotating shaft 21 in the vent chamber 14, and an air passage 25 connected with the vent hole 24 is provided in the rotating shaft 21 and the support rod 22, and the air passage 25 is communicated with the air passage 8.

[0038] When connecting, it is only necessary to conveniently insert the rotating shaft 21 into the rotating cylinder 13, and then lay it flat on the ground. After that, start to fill air into the air passage 8. While filling the gas, the pressure in the cylindrical airbag 7 gradually increases, so the pressure in the piston chamber 15 also increases. After increasing to a certain extent, the air pressure pushes the piston body 16 and the plug 17 to move, so that the plug 17 is inserted into the socket 23, thereby completing the relative connection between the two assembly units 2. At the same time, since the piston body 16 no longer blocks the connecting pipe 20, the connecting pipe 20 is connected to the piston chamber 15, and then the gas enters the ventilation chamber 14, and through the ventilation hole 24 on the rotating shaft 21, the gas enters the air passage 8 of the other assembly unit 2. The above operation is simple, and only one assembly unit 2 needs to be ventilated.

[0039] A switch valve 26 for opening and closing the gas flow is provided on the connecting block 12 and the support rod 22. Through the switch valve 26, the user can conveniently control the flow direction of the gas as needed, thereby completing installation or disassembly.

[0040] The hemostatic airbag 27 is also included. The hemostatic airbag 27 is annularly arranged. The elasticity of the outer surface of the hemostatic airbag 27 is less than that of the inner surface. The hemostatic airbag 27 is connected to an inflation device 32, and the inflation device 32 is connected to the deflation valve 10. Since the elasticity of the outer surface of the hemostatic airbag 27 is relatively small, the deformation of the inner surface becomes larger after inflation, so the volume of the hemostatic airbag 27 extends inward, thereby pressing the wound, thereby achieving the purpose of temporary hemostasis.

[0041] The frame fixing airbag 28 is also included. Velcro 29 is provided on both sides of the frame fixing airbag 28. The Velcro 29 are connected to each other to form a cylinder with a circular cross section. A fixing sheet 30 is provided in parallel in the frame fixing airbag 28. The frame fixing airbag 28 is connected to an inflating device 32. The inflating device 32 is connected to the deflation valve 10. The frame fixing airbag 28 can be conveniently installed to the position where it needs to be installed through the Velcro 29. At the same time, the position where the Velcro 29 is connected can also determine the size of the frame fixing airbag 28. At the same time, the fixing sheet 30 can play a supporting role, and the airbag can fully contact the human body, so as to temporarily fix the fracture well.

[0042] The neck fixing airbag 31 is also included. The neck fixing airbag 31 includes an upper fixing part 311 in contact with the chin and the head and a lower fixing part 312 in contact with the shoulder. The lower fixing part 312 is connected to a fixing cylinder 313 for placing the neck. An annular airbag 314 is connected between the fixing cylinder 313 and the upper fixing part 311. The neck fixing airbag 31 is connected to an inflating device 32, and the inflating device 32 is connected to the deflation valve 10. Since the upper fixing part 311 is relatively fixed to the chin and the head, and the lower fixing part 312 is relatively fixed to the neck, at this time, the annular airbag 314 is inflated, and due to its increased volume, pressure is generated on the chin, the head and the neck at the same time, thereby generating an upward supporting force on the neck and keeping it immovable, thereby completing a good fixation of the neck.

[0043] The inflating device 32 includes an inflating tube 321, and the inflating tube 321 is connected to an inflating check valve 322, and the inflating check valve 322 is connected to the deflation valve 10. Through the inflating tube 321, when performing emergency treatment, the gas in the cylindrical airbag 7 can be used for temporary operation, so that no additional inflating device 32 is required, and it is more suitable for on-site use.

[0044] Both ends of the side 5 are connected with handles 33. The use and transportation of the stretcher body 1 can be easily completed through the handles 33.

[0045] In summary, the beneficial effects of the present invention are: (1) the assembly units 2 can be easily assembled together to form the stretcher body 1, so the transportation and placement of the stretcher body 1 saves space and can meet the requirements for people of different heights; (2) the cylindrical airbag 7 has greater cushioning properties, which can ensure the comfort and safety of the injured during transportation; (3) after assembly, only one assembly unit 2 needs to be inflated, so the operation steps are more streamlined. At the same time, the hemostatic airbag 27, the skeleton fixing airbag 28 and the neck fixing airbag 31 can better realize various emergency functions applicable to the accident scene, and have a wide range of applications.
