[0002] The emergency department is the department with the most concentrated patients with moderate to severe symptoms, the most diseases, and the heaviest rescue and management tasks in the hospital. Many of the patients in the emergency department are patients transported from traffic accidents, construction accidents, natural disasters or explosion sites. The transport stretcher is the main carrier for transporting patients to ambulances and from ambulances to departments within the hospital. In the process of transporting patients, ambulances usually use conventional stretchers for transfer. Conventional stretchers are installed on stretcher carts, and four wheels are installed under the stretcher cart. After the patient lies on the stretcher, the medical staff pushes the stretcher cart to push the patient to the ambulance. However, in actual use, the area where the existing patients are located may have complex road conditions, and the stretcher cart may not be able to pass. Moreover, the stretcher and stretcher cart are integrated, and the patient can only be lifted out with door panels or other plate-like objects and then transported with a stretcher cart. The use is relatively limited, and it is easy to cause secondary injuries to the patient when transporting the patient with door panels or other plate-like objects.

[0003] In addition, on rainy days or inclement weather, the stretcher cannot be effectively protected from rain and can only be covered on the patient with a rainproof cloth for simple rain protection, which makes the patient on the stretcher vulnerable to rain, increases the patient's discomfort and may even aggravate the condition. Therefore, there is an urgent need for a transport stretcher that is convenient for transporting patients in complex terrains.

Detailed implementation manners

[0032] The following will describe in detail the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Figure 1-12 Embodiment 1

[0033] As shown in Figure 1 , 2 and 3, an emergency transfer stretcher mainly includes a stretcher main body 1, a support frame 2, a quick disassembly and assembly component 3, and a rain protection component 4. The stretcher main body 1 is arranged on the support frame 2 through the quick disassembly and assembly component 3, and the stretcher main body 1 is detachable relative to the support frame 2 through the quick disassembly and assembly component 3. The rain protection component 4 for rain shielding of the stretcher main body 1 is arranged on the stretcher main body 1, and the patient on the stretcher main body 1 can be shielded from wind and rain through the rain protection component 4.

[0034] The support frame 2 is an existing device, and the whole is a frame structure. Four wheels that can be pushed to walk are fixed under the support frame 2. For the convenience of rescue and ambulance use, the support frame 2 can be folded into the ambulance. This is an existing structure and has been a mature technology, which is widely used in existing ambulance rescue and can be directly used.

[0035] As shown in Figure 3 , 4 , 5 and 6, the stretcher main body 1 includes side rods 102 and cross bars. The side rods 102 are hollow aluminum alloy tubes with a "day" - shaped cross - section. The side rods 102 have the characteristics of light weight, strong load - bearing capacity and stable structure as a whole. There are two side rods 102 distributed parallel to each other on the left and right. The two side rods 102 are connected together by three cross bars. A "U" - shaped push - pull handle 103 is respectively arranged at the ends of the two side rods 102. The push - pull handle 103 is bent from a hollow round tube. The push - pull handle 103 can be pushed, pulled and used to lift the stretcher main body 1. After the stretcher main body 1 is installed on the support frame 2, the support frame 2 can be moved through the push - pull handle 103.

[0036] A cushion body 101 for the patient to lie on is arranged above the stretcher main body 1. The cushion body 101 is laid on the cross bars as a whole, and in order to facilitate the fixation of the patient and improve the comfort of the patient, the upper surface of the cushion body 101 in contact with the patient's body is an inward - concave arc, and the patient lies in the concave pit of the arc of the cushion body 101.

[0037] The cushion body 101 is composed of two parts, namely a back cushion 105 and a leg cushion 106. Among them, in order to improve the comfort of the patient, the angle of the back cushion 105 relative to the stretcher main body 1 is adjustable. By adjusting the angle of the back cushion 105, the back of the patient can be lifted, improving the comfort of the patient. The adjustment of the angle of the back cushion 105 is an existing technology and is a well - known problem for those skilled in the art. For example, the angle can be adjusted through a hydraulic support rod.

[0038] In order to improve the patient's comfort and prevent the patient's room temperature from being too high in cold weather, the cushion body 101 is designed to be multi-layered, and a heating component is arranged in the multi-layer cushion body 101, wherein the lower layer of the cushion body 101 is a support layer 54 with a certain strength, and a layer of sponge with a certain hardness is laid on the support layer 54 to improve the comfort of the patient lying on the cushion body 101, and a heat preservation layer 53 for heat preservation is laid on the sponge, and a reflective layer 52 is laid on the heat preservation layer 53. The setting of the reflective layer 52 effectively avoids the loss of heat, and the heat preservation layer 53 is placed on the reflective layer 52. A heating wire 51 is laid on the side, and the heating wire 51 is powered by a power supply arranged on the back of the stretcher body 1. The heating wire 51 is evenly distributed on the upper surface of the reflective layer 52. The pad body 101 is heated by the heating wire 51, which effectively prevents the patient lying on the stretcher body 1 from suffering from hypothermia in cold weather. A layer of sponge is laid on the top of the heating wire 51. At the same time, in order to facilitate the disinfection and cleaning of the pad body 101, a layer of leather is covered on the outer surface of the pad body 101. After use, the stretcher body 1 can be wiped clean and disinfected with alcohol or disinfectant.

[0039] Definition: In this embodiment, the direction where the support frame 2 is located and points to the ground is downward, and the direction where the stretcher body 1 is located and points to the sky is upward.

[0040] In order to facilitate the fixation of the patient lying on the cushion body 101 and prevent the patient from shaking and causing secondary injury during transportation, a head restraint airbag 109 is provided on the back pad 105 of the cushion body 101, and two sets of fixing belts 111 are provided on the leg pad 106, wherein the two sets of fixing belts 111 are distributed at intervals and are respectively used to fix the patient's torso and legs.

[0041] The head restraint airbag 109 is a hollow airbag with a rectangular cross-section. The lower part of the head restraint airbag 109 is fixed on the back pad 101. The head restraint airbag 109 is distributed at two intervals. The patient's head is placed in the interval between the two head restraint airbags 109. After being inflated, the two head restraint airbags 109 will fit the patient's head to restrain and fix the position of the patient's head to prevent the patient's head from shaking during transportation and causing secondary injury. A cloth restraint belt 110 connecting the two head restraint airbags 109 is arranged above the two head restraint airbags 109. After the patient's head is limited by the head restraint airbag 109, the restraint belt 110 rests on the patient's forehead to assist the head restraint airbag 109 in limiting and fixing the patient's head. It is easy to use and firmly fixed.

[0042] The inflation and deflation of the head restraint airbag 109 can be controlled by an air pump 72 arranged on the back of the stretcher body 1. The air pump 72 is connected to the head restraint airbag 109 through an air duct, and the inflation and deflation of the head restraint airbag 109 are achieved through the air pump 72.

[0043] Each set of fixing straps 111 is composed of two sub-fixing straps, and the two sub-fixing straps are connected by a buckle 112. The letter fasteners on the buckle 112 are fixed to one end of a sub-fixing strap respectively. One end of one of the two sub-fixing straps is connected to the sub-fastener of the buckle 112, and the other end is fixed to the leg pad 106. One end of the other of the two sub-fixing straps is connected to the female fastener of the buckle 112, and the other end passes through the leg pad 106 and the fixing strap tightness adjustment component 6 to be exposed to the outside. Pulling the fixing strap 111 exposed to the outside can adjust the tightness of the fixing strap 111, which is easy to use.

[0044] In order to facilitate the infusion of patients during transport, a drip rod 107 is provided on the upper surface of the side rod 102 . The drip rod 107 is provided on both side rods 102 , and is provided on one end of the side rod 102 close to the back pad 105 .

[0045] The drip rod 107 is a hollow metal tube, one end of which is hingedly fixed to the side rod 102 via a hinge seat 113, and the other end of the drip rod 107 is provided with a hook for hanging a medicine bottle. In order to facilitate use, the drip rod 107 is foldable and storable. When not in use, the drip rod 107 can be folded and stored, which is convenient to use.

[0046] In order to fold and store the drip rod 107, a limiter 114 is provided at the hinge of the drip rod 107, the lower surface of the limiter 114 is fitted with the upper surface of the side rod 102, the cross-section of the limiter 114 has a "U" shape, and the two straight arms of the limiter 114 are provided with oblong sliding holes spaced apart from top to bottom, and pins connected to the drip rod 107 are provided in the sliding holes. The limiter 114 is pressed, and the arc-shaped inner surface of the limiter 114 can contact the surface of the drip rod 107, and the diameter of the drip rod 107 is the same as the diameter of the arc of the inner wall of the drip rod 107. After the inner arc of the limiter 114 is fitted with the surface of the drip rod 107, the drip rod 107 can rotate along the hinge, thereby realizing the folding and storage of the drip rod 107.

[0047] When the drip rod 107 is in use, in order to limit the drip rod 107, a first pressure spring 115 is arranged between the inner arc surface of the limiter 114 and the drip rod 107, one end of the first pressure spring 115 is against the inner arc surface of the limiter 114, and the other end is embedded in the inside of the drip rod 107. When in use, the limiter 114 is unfolded under the action of the first pressure spring 115, and the drip rod 107 cannot be folded. When folding is required, the limiter 114 is pressed and the first pressure spring 115 is compressed. When the inner arc surface of the limiter 114 is in contact with the outer surface of the drip rod 107, the drip rod 107 can be rotated and folded along the hinge with the hinge seat 113.

[0048] In order to facilitate the rescue of transferred patients, an oxygen cylinder fixing frame 108 is welded on the outer side surface of the side rod 102 of the stretcher body 1. The oxygen cylinder fixing frame 108 can be opened and the oxygen cylinder can be placed in the oxygen cylinder fixing frame 108, avoiding the need for an additional rescuer to hold an oxygen bag during transfer. The method is convenient to use and reduces waste of personnel.

[0049] When encountering complex road conditions and the supporting frame 2 cannot be pushed, it is necessary to disassemble the stretcher body 1 and use the stretcher body 1 to carry the patient. In order to facilitate carrying and reduce the physical consumption of personnel, a retractable lifting rod 104 is respectively provided at both ends of each side rod 102. The lifting rod 104 is made of a stainless steel metal pipe with strong weighing capacity. The lifting rod 104 can be retracted and inserted into the opening below the side rod 102. When the patient is carried for a long distance, four lifting rods 104 can be drawn out and carried by multiple people at the same time, which improves the transportation speed while reducing the physical consumption of personnel.

[0050] like Figure 3 and 6 As shown, in order to facilitate the adjustment of the tightness of the fixing belt 111, the fixing belt tightness adjustment component 6 includes an adjustment component mounting box 61 and a roller 62. The adjustment component mounting box 61 is fixed to the upper surface of the side rod 102 by screws. A rectangular through hole penetrating the adjustment component mounting box 61 is opened on the side of the adjustment component mounting box 61 near the fixing belt 111, and the fixing belt 111 passes through the adjustment component mounting box 61 through the rectangular through hole.

[0051] The roller 62 is a cylindrical shaft with a circular cross section. The roller 62 is distributed in parallel up and down in the adjustment component installation box 61, and the adjustment component installation box 61 can rotate freely in the adjustment component installation box 61. A plurality of limiting rolling teeth 64 are evenly arranged on the surface of the roller 62 perpendicular to the roller 62, and the interval between the limiting rolling teeth 64 on the two rollers 62 is less than the thickness of the fixing belt 111. When the fixing belt 111 is pulled, the roller 62 rotates accordingly. In order to limit the rotation of the roller 62, the adjustment is achieved. In order to achieve the tightening and loosening effect of the fixing belt 111, a second ratchet pawl mechanism 63 is fixed coaxially with the roller 62 at the end of the roller 62, the ratchet on the second ratchet pawl mechanism 63 is fixed on the roller 62, and moves synchronously with the roller 62, the pawl on the second ratchet pawl mechanism 63 is arranged on the adjustment component mounting box 61, and in order to release the limit of the pawl on the ratchet, a reset rod is arranged on the pawl and passes through the adjustment component mounting box 61, and the limit of the pawl on the ratchet can be released by pulling the reset rod, which is easy to use.

[0052] The use process of the fixing belt 111 and the fixing belt tension adjustment component 6 is as follows: when the patient lies on the cushion body 101, the two sets of fixing belts 111 are used to fix the patient's torso and legs respectively. The fixing method is to buckle the buckle 112 on the sub-fixing belt, and then pull the sub-fixing belt that passes through the fixing belt tension adjustment component 6 and is exposed to the outside. At this time, the sub-fixing belt drives the roller 62 to rotate. At the same time, under the action of the second ratchet pawl mechanism 63, the roller 62 can only rotate in one direction, thereby completing the contraction and fixing the patient on the cushion body 101. When the transfer is completed, the buckle 112 can be unfastened to lift the patient off the cushion body 101. After use, press the reset rod on the pawl in the second ratchet pawl mechanism 63 to release the limit of the pawl on the ratchet wheel. At this time, the roller 62 can rotate in both directions, and the tightened sub-fixing belt is pulled again to reset the sub-fixing belt for the convenience of use by the lower patient. At the same time, a limit block is fixed to the end of the exposed sub-fixing belt to prevent the sub-fixing belt from being pulled out of the adjustment component installation box 61.

[0053] like Figure 3 , 9 As shown in FIG10 , in order to facilitate the rapid disassembly and assembly between the stretcher body 1 and the supporting frame 2 and facilitate the transportation of patients in complex road conditions, the supporting frame 2 and the stretcher body 1 are rapidly disassembled and assembled through a rapid disassembly and assembly component 3 .

[0054] The quick disassembly and assembly component 3 includes a lock tongue mounting box 304 and a lock buckle mounting seat 306. The lock tongue mounting box 304 is fixed below the cross bar of the stretcher body 1, and the lock buckle mounting seat 306 is fixed on the cross bar above the supporting frame 2. The lock tongue mounting box 304 is a rectangular block, and an arc-shaped groove is provided on the lower surface of the lock tongue mounting box 304. The lock buckle mounting seat 306 is a rectangular plate, and an arc-shaped boss is provided on the upper surface of the lock buckle mounting seat 306. The groove on the lock tongue mounting box 304 cooperates with the boss on the lock buckle mounting seat 306, and the lock tongue mounting box 304 can be stuck on the lock buckle mounting seat 306.

[0055] A circular lock tongue mounting hole 310 is concavely provided on the side of the lock tongue mounting box 304 perpendicular to the lock tongue mounting box 304, and the lock tongue 301 is inserted into the lock tongue mounting hole 310. The lock tongue 301 is a metal rod with a circular cross-section. The diameter of one end of the lock tongue 301 is the same as the diameter of the lock tongue mounting hole 310, and the diameter of the other part is slightly smaller than the lock tongue mounting hole 310. A second pressure spring 311 is sleeved on the smaller diameter section of the lock tongue 301. One end of the second pressure spring 311 is against the step surface of the lock tongue 301, and the other end passes through a sealing ring fixed on the lock tongue mounting box 304 to close the lock tongue mounting hole 310. When the lock tongue 301 is pulled, the smaller diameter end of the lock tongue 301 can pass through the sealing ring, and at this time, the second pressure spring 311 is compressed.

[0056] In order to facilitate fixation, a socket is opened on the lock tongue mounting box 304 to expose the larger diameter section of the lock tongue 301. At the same time, a 45° cut is made on this section of the lock tongue 301, and the cut surface is arc-shaped, so that the lock buckle 302 fixed on the lock buckle mounting seat 306 can pass through the socket on the lock tongue mounting box 304, and squeeze the lock tongue 301 into the lock tongue mounting hole 310 through the arc surface on the lock tongue 301. When the lock buckle 302 is fully inserted into the socket, the lock tongue 301 will rebound under the action of the second pressure spring 311, pass through the circular hole on the lock buckle 302, and complete the fixation between the lock buckle 302 and the lock tongue 301.

[0057] In order to facilitate the lock buckle 302 to push the lock tongue 301 along the inclined surface of the lock tongue 301 to retract into the lock tongue installation hole 310, the arc surface where the lock buckle 302 contacts the lock tongue 301 is rounded, and the diameter of the circular hole on the lock tongue 301 is slightly larger than the maximum diameter of the lock tongue 301.

[0058] In order to improve the stability of the connection and fixation between the stretcher body 1 and the supporting frame 2, two lock mounting seats 306 are provided on the supporting frame 2, and the two lock mounting seats 306 are respectively arranged at the two ends of the supporting frame 2, and a lock 302 is fixed at each end of each lock mounting seat 306.
