DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figures 1 to 10 The present invention provides a technical solution: a new type of multifunctional medical rescue bed, comprising a bed board 1 for supporting a patient and a bed frame for supporting the bed board 1, the bed board 1 is provided with a body position limiting structure for preventing the patient from interrupting the chest compression process; the body position limiting structure comprises a swing rod 2 that can swing freely in the vertical direction, the middle part of the swing rod 2 is rotated on the bed board 1 with a fixed axis, and one end of the swing rod 2 facing the middle part of the bed board 1 is provided with a positioning component for fixing the legs of medical staff; the end of the swing rod 2 away from the positioning component is provided with a transverse turning rod 16 that can move freely in the horizontal direction, and the transverse turning rod 16 is provided with an airway adjustment component for adjusting the position of the patient's head; the body position limiting structure also includes two groups of abutment plates 24 that contact the buttocks of the medical staff performing the chest compression process, and the bed board 1 is provided with a positioning assisting component that drives the abutment plates 24 to push the buttocks of the medical staff.

[0033] like Figure 1 and Figure 2 As shown, when a patient who is in a coma or whose heart has stopped and who needs chest compression is transferred via a rescue bed, in order to ensure the timeliness of the rescue, during the patient's transfer, the patient is made to lie flat on the bed board 1 with his back, and at the same time, the medical staff kneels on the bed board 1 with their legs apart in a more balanced manner to facilitate chest compressions on the patient.

[0034] At the same time, in the process of transferring the patient to the operating room or examination room via the emergency bed, the legs of the medical staff performing chest compression rescue are fixed by the positioning component, thereby ensuring the stability of the medical staff when moving the bed and reducing the risk of falling caused by bumps in movement or emergency situations. At the same time, the medical staff is allowed to perform chest compression and other rescue operations uninterruptedly during the transfer process, which is crucial to maintaining the patient's vital signs. The positioning component allows the medical staff to focus more on rescue measures rather than maintaining their own balance, thereby improving the operational efficiency during the rescue process.

[0035] Moreover, while fixing the medical staff's legs, the airway adjustment component can ensure that the patient's airway is unobstructed, thereby ensuring that oxygen can smoothly enter the lungs and provide the necessary oxygenated blood for cardiac resuscitation. In addition, an unobstructed airway can increase the blood circulation efficiency during chest compression and improve the success rate of resuscitation.

[0036] At the same time, when the medical staff is performing chest compressions, their backs are bent and their hips swing slightly back and forth during the compression process. In order to reduce the strength of the medical staff during chest compressions and to increase the time and efficiency of chest compressions, the power-assisting component can push the hips of the medical staff on the bed back and forth when the bed moves, thereby providing assistance in the process of pressing the patient's chest to avoid the medical staff from losing strength.

[0037] In one of the more preferred embodiments, the positioning assembly includes a guide seat 8 that can move freely in the vertical direction, a limit frame 9 is fixedly connected to the lower surface of the bed board 1, and a vertical slide groove is provided on the limit frame 9 for the guide seat 8 to slide in the vertical direction, and two groups of fixing components are provided on the guide seat 8 to fix the single legs of the medical staff respectively; the fixing assembly includes two groups of transverse displacement seats 28 that can move synchronously toward or away from each other, and the two groups of transverse displacement seats 28 are respectively fixedly connected with relatively arranged outer fixed seats 10 and inner fixed seats 11; a rectangular groove is provided on the bed board 1 for the outer fixed seat 10 and the inner fixed seat 11 to pass through, and the opposite surfaces of the outer fixed seat 10 and the inner fixed seat 11 are both arc-shaped structures; the guide seat 8 is provided with a transverse slide groove for the transverse displacement seat 28 to slide horizontally.

[0038] like Figure 1-Figure 4 As shown, in this embodiment, the guide seat 8 that moves freely in the vertical direction drives the multiple groups of transverse seats 28 thereon to rise synchronously, thereby driving the outer fixed seat 10 and the inner fixed seat 11 set on the transverse seat 28 to be exposed to a certain height of the bed board 1 while rising. At the same time, the outer fixed seat 10 and the inner fixed seat 11 can move synchronously toward or away from each other in the horizontal direction. Therefore, when the rescue bed is actually used, when the medical staff performing chest compressions kneels on the bed body 1, their calves are located between the outer fixed seat 10 and the inner fixed seat 11, and the legs of the medical staff are clamped and fixed by the outer fixed seat 10 and the inner fixed seat 11 with gradually reduced horizontal spacing.

[0039] Among them, the side of the outer seat 10 and the inner seat 11 facing the medical staff's legs is an arc-shaped structure, and the arc-shaped structure is made of rubber. Therefore, the outer seat 10 and the inner seat 11 can fit the medical staff's legs more closely. At the same time, the rubber material can avoid causing discomfort to the medical staff's legs and can adapt to medical staff with different leg circumferences.

[0040] Based on the fixing component embodiment, the limit seat 12 is fixed by bolts on the lower surface of the bed board 1, and the transverse displacement seat 28 is fixedly connected to the limit pin 14 on one side of the limit seat 12. The limit seat 12 is provided with a limit groove 13 for the limit pin 14 to slide, and the limit groove 13 includes an integrally formed vertical groove portion 131 and a horizontal inclined groove portion 132.

[0041] like Figure 3 , Figure 4 and Fig. 9As shown, in the present embodiment, when the guide seat 8 moves freely in the vertical direction, it can drive the horizontally sliding seat 28 thereon to rise and fall synchronously. At the same time, the limit pin 14 fixedly arranged on the horizontally sliding seat 28 is slidably connected to the limit seat 12 through the limit groove 13. Therefore, when the horizontally sliding seat 28 rises in the initial state, the limit pin 14 slides on the vertical groove 131. At this time, the inner fixed seat 11 and the outer fixed seat 10 will not move in the horizontal direction, and both will only gradually rise with the horizontally sliding seat 28.

[0042] As the guide seat 8 continues to rise, the transverse seat 28 drives the inner seat 11 and the outer seat 10 to gradually rise. When the limit pin 14 is at the junction of the vertical groove 131 and the horizontal inclined groove 132, the horizontal heights of the outer seat 10 and the inner seat 11 are both greater than the horizontal height of the upper surface of the bed board 1. At this time, as the transverse seat 28 continues to rise, the limit pin 14 slides on the horizontal inclined groove 132. At this time, the transverse seat 28 can drive the outer seat 10 and the inner seat 11 to move synchronously toward the legs of the medical staff while driving the outer seat 10 and the inner seat 11 to rise, that is, the horizontal distance between the outer seat 10 and the inner seat 11 gradually decreases until the arc structure provided by the two is in close contact with the legs of the medical staff, thereby completing the fixing of the legs of the medical staff.

[0043] Furthermore, a connecting rod 3 which can rotate freely in the vertical direction is provided under the bed board 1, and the connecting rod 3 rotates on the bed board 1 on a fixed axis. The end of the connecting rod 3 away from the bed board 1 is fixedly connected with a give way pin 4, and the rocker arm 2 is provided with a give way groove 201 for the give way pin 4 to slide; the end of the rocker arm 2 away from the connecting rod 3 is fixedly connected with a transverse column 7, and a guide transverse groove 801 for the transverse column 7 to slide horizontally is provided on the guide seat 8; the end of the rocker arm 2 away from the transverse column 7 is fixedly rotated with a driven rod 15 on an axis, and the end of the driven rod 15 away from the rocker arm 2 is fixedly rotated on a transverse turning rod 16, and a connecting column 18 is fixedly connected to the lower surface of the bed board 1, and a rectangular block 17 is fixedly connected to the end of the connecting column 18 away from the bed board 1, and a rectangular through groove is provided on the rectangular block 17 for the transverse turning rod 16 to slide horizontally through.

[0044] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the connecting rod 3 is driven to rotate freely in the vertical direction by a motor fixedly arranged on the bed board 1, wherein the yield pin 4 fixedly arranged at the end of the connecting rod 3 is slidably connected to the rocker arm 2 through the yield groove 201, and the middle part of the rocker arm 2 rotates on the bed board 1 on a fixed axis. Therefore, during the rotation of the connecting rod 3, the horizontal height of the yield pin 4 at its end changes, and then the rocker arm 2 is driven to swing on a fixed axis in the vertical direction through the yield pin 4.

[0045] At the same time, when the swing arm 2 is in the process of vertical swinging, the horizontal height and horizontal position of the transverse column 7 fixed at its end change synchronously. When the horizontal height of the transverse column 7 changes, it can drive the guide seat 8 to move in the vertical direction, and then drive the positioning assembly to operate through the guide seat 8, so as to clamp and fix the legs of the medical staff.

[0046] It should be noted that, by opening a guide transverse groove 801 for the sliding of the transverse column 7 on the guide seat 8 to adapt to the change of the horizontal position of the transverse column 7, the existence of the guide seat 8 is avoided to cause motion interference in the swinging process of the rocker arm 2, and it can also ensure that the guide seat 8 can follow the transverse column 7 to perform lifting and lowering movements.

[0047] At the same time, when the rocker arm 2 swings on a fixed axis, it can drive the follower rod 15 arranged at the other end thereof to swing, wherein the follower rod 15 rotates on a fixed axis on the transverse crank 16, and the transverse crank 16 can only move in the horizontal direction under the restriction of the rectangular block 17. Therefore, when the follower rod 15 swings, it can drive the transverse crank 16 to move horizontally.

[0048] Furthermore, based on the positioning component embodiment, the airway adjustment component includes a U-shaped rod 19 that can move freely in the horizontal direction, a groove body is provided on the transverse turning rod 16 for the U-shaped rod 19 to slide vertically, a forehead push plate 20 is provided in the middle of the U-shaped rod 19, and the forehead push plate 20 is fixedly connected to the side of the U-shaped rod 19 facing the bed board 1, and the airway adjustment component also includes a lifting component for supporting the patient's neck.

[0049] See also Figure 1 In this embodiment, the up and down displacement of the forehead push plate 20 can cooperate with the neck lifting assembly to limit the position of the patient's neck and head. This is beneficial for emergency rescue to avoid secondary injuries, such as when the patient is unconscious or in a coma, or has cervical trauma or fracture.

[0050] A positioning seat 21 is fixedly connected to the lower surface of the bed board 1, and a positioning pin 23 is fixedly connected to the side of the U-shaped rod 19 facing the positioning seat 21. A positioning groove 22 for the positioning pin 23 to slide is opened on the positioning seat 21, and the positioning groove 22 includes a steep groove part 221 and a slow groove part 222 formed in one piece.

[0051] The lifting assembly includes a neck seat 6 arranged on the bed board 1, and a placement groove is opened on the bed board 1 to accommodate the neck seat 6 and allow the neck seat 6 to slide vertically. A cam 5 is provided below the neck seat 6, and the cam 5 is coaxially fixed with the end of the connecting rod 3 away from the rocker arm 2, and the outer peripheral surface of the cam 5 is in sliding contact with the lower surface of the neck seat 6.

[0052] like Figure 1 , Figure 2 and Figure 6As shown, when the connecting rod 3 rotates in the vertical direction, the cam 5 coaxially fixed with the connecting rod 3 can be driven to rotate synchronously. Since the cam 5 is in sliding contact with the neck seat 6, when the integrally formed protrusion in the cam 5 contacts the neck seat 6, the neck seat 6 can be driven to move upward. When the patient lies on the bed board 1, the patient's neck is located above the neck seat 6. Therefore, the patient's neck is lifted by the rising process of the neck seat 6.

[0053] At the same time, the swing arm 2 swings with the rotation of the connecting rod 3, and the swinging process of the swing arm 2 drives the horizontal movement of the transverse turning rod 16, wherein the transverse turning rod 16 is vertically slid by a U-shaped rod 19 through a groove body, so the U-shaped rod 19 can move synchronously with the transverse turning rod 16 in the horizontal direction. However, the positioning pin 23 fixed on the U-shaped rod 19 is slidably connected to the positioning seat 21 through the positioning groove 22, and the positioning seat 21 is fixed on the bed board 1. Therefore, when the U-shaped rod 19 initially moves in the horizontal direction, the positioning pin 23 slides on the steep groove portion 221, thereby enabling the U-shaped rod 19 to move downward a large distance during a short horizontal movement. It should be noted that when the patient lies on the bed board, the patient's forehead position roughly corresponds to the position of the forehead pushing plate 20. Therefore, through the horizontal movement of the U-shaped rod 19, the forehead pushing plate 20 can be driven to move quickly toward the patient's forehead position.

[0054] Among them, the forehead push board 20 is fixedly connected with an airbag on one side facing the bed board 1, so that the forehead push board 20 will not excessively squeeze the patient's forehead. As the U-shaped rod 19 continues to move in the horizontal direction, the positioning pin 23 slides on the buffer groove 222. Therefore, after the forehead push board 20 contacts the patient's forehead, the forehead push board 20 can be driven to move slowly downward while moving horizontally. The purpose is to make the movement trajectory of the forehead push board 20 adapt to the patient's head shape, and drive the patient's chin to tilt up through the friction between the forehead push board 20 and the patient's head. By using it in conjunction with the lifting component, the purpose of supporting the patient's neck and buffering the patient's forehead position can be achieved, so that the patient's airway remains unobstructed, thereby ensuring that oxygen can smoothly enter the lungs and provide the necessary oxygenated blood to flow to the brain and other important organs. Secondly, during cardiopulmonary resuscitation, opening the airway can increase the effectiveness of chest compression and improve the success rate of resuscitation.

[0055] Based on the embodiment of the airway adjustment assembly, the positioning assist assembly includes a V-shaped shift rod 29 that moves freely in the vertical direction, a slot body 3 is provided on the bed board 1 for the V-shaped shift rod 29 to slide through, a push plate 30 is fixedly connected to the top of the V-shaped shift rod 29, and the push plate 30 is in sliding contact with the stop plate 24;

[0056] The positioning assisting assembly also includes a driven shifting wheel 35 which rotates on a fixed axis on the bed frame. An eccentric circle 34 is coaxially fixed to the driven shifting wheel 35. An adjusting pin 33 is fixedly connected to one end of the V-shaped shifting rod 29 facing the eccentric circle 34. A circular groove 341 is provided on the eccentric circle 34 for the adjusting pin 33 to slide.

[0057] The two groups of abutment plates 24 are respectively axially rotated on the inner fixed seat 11, an L-shaped rod 25 is fixedly connected to the upper surface of the outer fixed seat 10, and a T-shaped clamping block 27 is fixedly connected to the side of the abutment plate 24 facing the L-shaped rod 25;

[0058] A T-shaped clamping groove 26 is formed at a position corresponding to the T-shaped clamping block 27 of the L-shaped rod 25 , and the opposite surfaces of the T-shaped clamping block 27 and the L-shaped rod 25 are in sliding contact.

[0059] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Fig.10 As shown, when the positioning assembly fixes the patient's legs, the outer fixing seat 10 and the inner fixing seat 11 move toward each other, thereby driving the T-shaped clamping block 27 and the T-shaped clamping groove 26 opened on the L-shaped rod 25 to gradually decrease the distance, until the T-shaped clamping block 27 corresponds to the T-shaped clamping groove 26, the stop plate 24 will no longer be hindered by the L-shaped rod 25, because a torsion spring is provided between the stop plate 24 and the inner fixing seat 11 to drive the stop plate 24 to return to its initial position, the torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. Therefore, under the action of the torsion spring, the stop plate 24 deflects, and its deflection direction is toward the center line direction of the bed board 1. At this time, the vertical cross-section formed by the two groups of stop plates 24 is an inverted V shape, and the position of the two groups of stop plates 24 at this time is below the buttocks of the medical staff.

[0060] At the same time, in the process of transferring the patient through the bed, the driven transfer wheel 35 and the multiple sets of universal wheels arranged at the bottom of the bed frame are synchronously in contact with the ground, and the driven transfer wheel 35 can rotate as the bed moves. Among them, the adjusting pin 33 fixedly arranged at the bottom of the V-shaped transfer rod 29 is slidably connected to the eccentric circle 34 through the circular groove body 341, and the eccentric circle 34 coaxially fixes the driven transfer wheel 35. Therefore, as the driven transfer wheel 35 rotates, the V-shaped transfer rod 29 can reciprocate in the vertical direction, thereby driving the push plate 30 fixed at its top to rise and fall synchronously. At the same time, in the process of reciprocating and rising, the push plate 30 can repeatedly squeeze and push the two sets of abutment plates 24, thereby driving the two sets of abutment plates 24 to contact the buttocks of the medical staff, and driving the buttocks of the medical staff to move upward through the deflection of the abutment plates 24. The purpose is to provide assistance to the medical staff in the process of chest compression, thereby improving the rescue efficiency.

[0061] On the basis of the embodiment of the positioning assistance assembly, the lower surface of the bed board 1 is fixedly connected with an air cylinder 31, the V-shaped shift rod 29 slides through the two vertical side surfaces of the air cylinder 31, and the joint position of the V-shaped shift rod 29 and the air cylinder 31 is sealed, and the V-shaped shift rod 29 is fixedly connected with a piston plate 32, and the outer peripheral surface of the piston plate 32 is in sliding contact with the inner wall of the air cylinder 31;

[0062] The gas cylinder 31 is fixedly connected with two sets of one-way valves with openings facing opposite directions. The gas cylinder 31 is in gas communication with an oxygen supply hose that provides oxygen to the patient's oral cavity.

[0063] like Figure 2 and Figure 7 As shown, when the V-shaped shift rod 29 reciprocates in the vertical direction, it can drive the piston plate 32 fixed thereon to reciprocate and rise and fall in the air cylinder 31, thereby reciprocatingly sucking and exhausting the gas in the air cylinder 31 through the piston plate 32, wherein the air cylinder 31 is fixedly connected to an oxygen supply hose that provides oxygen to the patient's oral position. Therefore, during chest compression, oxygen can be actively supplied to the patient's oral cavity. Through the setting of two sets of one-way valves, the air circulation direction can be restricted so that the outside natural air can only enter the oxygen supply hose through the air cylinder 31. At the same time, a filter for filtering natural air is fixedly connected to the air inlet end of the air cylinder 31 to achieve the purpose of purifying the air.

[0064] It should be noted that when chest compressions are performed on a patient, the patient's chest cavity position becomes smaller due to external force, and in the actual rescue process, the compression process is completed as the medical staff exerts force on their hips and waist. Therefore, when the V-shaped shift rod 29 moves upward to push the medical staff to press, the lifting and lowering process of its piston plate 32 will not supply oxygen to the patient's mouth. The purpose is to avoid adverse effects on the patient's own breathing rhythm when the patient's chest cavity becomes smaller. At the same time, when no compression is performed, oxygen is supplied to the patient's mouth through the movement of the V-shaped shift rod 29, thereby ensuring that the patient's chest cavity is not squeezed during oxygen supply, so as to ensure that oxygen can smoothly enter the lungs.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
