Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a chest-extendable cardiopulmonary resuscitation bed. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) machines increase blood flow to the heart and brain in patients with cardiac arrest and act as a bridge between treatments including defibrillation, intravenous medication, cardiac catheterization, and other forms of revascularization, thereby improving the success rate of spontaneous circulation.

[0003] When performing cardiopulmonary resuscitation (CPR) on patients in the emergency room, a CPR machine needs to be installed on the resuscitation bed to perform CPR. However, due to the different body sizes of each patient, the relative position of the heart on the resuscitation bed is also different. Therefore, it is necessary to adjust the installation position of the CPR machine according to the patient's body size. At the same time, when the patient's condition is more urgent, it is necessary to transfer the patient to the emergency room for emergency treatment during the CPR process. During the patient transport, the emergency bed will be bumped, causing the relative position of the CPR machine and the patient's chest cavity to change, thereby reducing the efficiency of CPR.

[0004] When a cardiopulmonary resuscitation (CPR) machine is in operation, it continuously presses on the patient's chest, causing the patient to press down on the emergency bed. If the platform supporting the patient at the bottom is not strong enough, the patient's body will shift downwards as the CPR machine continues to operate, increasing the distance between the patient and the CPR machine, thereby reducing the efficiency of CPR.

[0005] Therefore, this application provides a chest-expandable cardiopulmonary resuscitation bed to meet the needs. Summary of the Invention

[0006] The technical problem this invention aims to solve is to provide a chest-retractable cardiopulmonary resuscitation (CPR) bed. By placing the patient on the bed, drive motors three and two align the center of the mounting plate with the patient's heart. Drive motor one drives a worm gear that meshes with two sets of worm wheels, thereby rotating two sets of drive rods. This causes four sets of push rods to push the mounting plate upwards, lifting the patient's chest cavity away from the bed. By inserting the top of the CPR machine into the mounting seat and engaging the end plates with the ends of the mounting plate, the CPR machine can perform CPR on the patient's heart and lungs. This addresses the problem that existing CPR beds are not suitable for patients of various body types and hinder the operation of the CPR machine.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A chest-extendable cardiopulmonary resuscitation bed includes a positioning device and a bed body. The top of the bed body has an ejection area on one side, and the ejection area extends through the inner wall of the bed body. The positioning device is located inside the ejection area and includes a self-ejection mechanism.

[0009] The self-ejecting mechanism includes a base slide plate, with inner slide tracks fixedly installed at each of the four corners of the top of the base slide plate. A support frame is fixedly installed at the center of the top of the base slide plate, and a worm gear is rotatably connected to the inner wall of the middle part of the support frame. A motor is fixedly installed at the bottom of the base slide plate, and the output shaft of the motor is fixedly connected to the end wall of the worm gear. Drive rods are rotatably connected to both sides of the center line of the top of the base slide plate. Worm wheels are fixedly installed in the middle of the two sets of drive rods. The worm wheels are located inside the support frame and are located on both sides of the worm gear, and both are meshed with the worm gear. Swing arms are fixedly installed on the end walls of both drive rods. Top rods are rotatably connected to the outer end walls of the four sets of swing arms. The top rods are located in the corresponding inner slide tracks and are connected to the inner wall of the inner slide tracks. The same assembly plate is fixedly installed on the top of the four sets of top rods. The two ends of the assembly plate can be snapped onto the pressure plates on both sides of the cardiopulmonary resuscitation machine.

[0010] Optionally, slide rails two are fixedly installed on both sides of the top of the ejection area, and the same limiting rod is fixedly installed at both ends of the top of the ejection area. Screws two are rotatably connected to both ends of the center of the top of the ejection area. The same bottom slide plate is slidably connected to the two sets of slide rails two. The limiting rod slides through the bottom of the bottom slide plate. The bottom of the bottom slide plate is provided with a screw hole and engages with screws two. Motor three is fixedly installed on the outer wall of the ejection area, and the output end of motor three is fixedly connected to the end wall of screw two. Slide rail one is fixedly installed on both sides of the top of the bottom slide plate. The bottom of the base slide plate is slidably connected to slide rail one. The same screw one is rotatably connected to the outer end walls of the bottom slide plate. Screw one engages with the bottom of the base slide plate. Motor two is fixedly installed on the outer wall of the bottom slide plate, and the output shaft of motor two is fixedly connected to the end wall of screw one.

[0011] Optionally, an L-shaped base plate is fixedly installed on the outer wall of the base plate. An L-shaped flip plate is rotatably connected to the top of the L-shaped base plate via a hinge. The L-shaped flip plate is located above the bed. The maximum flip angle between the L-shaped flip plate and the L-shaped base plate is 90°. The initial included angle between the L-shaped flip plate and the L-shaped base plate is 90°. A card slot is provided at the bottom front end of the L-shaped flip plate. The inner wall of the card slot can be engaged with the top shell of the cardiopulmonary resuscitation machine. The centerline of the card slot coincides with the centerline of the assembly plate.

[0012] Optionally, a strip-shaped slat is provided on the outer side of the top of the bed, and a strip-shaped mating slide is slidably connected to the top of the bed. The strip-shaped mating slide is inserted into the strip-shaped slat, and the bottom of the strip-shaped mating slide is movably engaged with the top of the ejection area. A wheel slide seat is fixedly installed at the bottom of the bed.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above scheme, the patient is placed on the bed. The position of the bottom sliding plate on the Y-axis is adjusted by drive motor three, and the position of the base sliding plate on the X-axis is adjusted by drive motor two, so that the middle of the assembly plate is aligned with the patient's heart. At the same time, when the base sliding plate moves on the X and Y axes, it can drive the L-shaped bottom plate to move synchronously, thereby ensuring that the position of the card holder is also aligned with the heart. Then, drive motor one drives the worm gear to mesh with two sets of worm wheels, thereby driving two sets of drive rods to rotate, causing the four sets of push rods to push the assembly plate upward, pushing the patient's chest cavity away from the bed. By inserting the top of the cardiopulmonary resuscitation machine into the card holder and locking the two end pressure plates with the two ends of the assembly plate, the cardiopulmonary resuscitation machine can perform cardiopulmonary resuscitation operations on the patient.

[0015] During the transfer of a patient during cardiopulmonary resuscitation (CPR), the bed shakes continuously, causing the alignment device to vibrate. Because the L-shaped base plate is installed together with the base plate, the L-shaped base plate can always follow the movement when the base plate vibrates, ensuring that the relative position of the mounting plate and the card holder does not change, thus maximizing the effectiveness of CPR. At the same time, the CPR machine also causes the bed to vibrate during operation. This device can prevent the CPR machine from being misaligned with the patient's chest cavity during operation.

[0016] During the operation of the cardiopulmonary resuscitation machine, the output end of the machine applies pressure to the patient, thereby pressing the assembly plate. The cooperation between the worm gear and the worm wheel effectively prevents the assembly plate from shifting downwards during the pressing process. Attached Figure Description

[0032] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiment of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0033] The retractable chest resuscitation bed provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0034] like Figures 1 to 12As shown, an embodiment of the present invention provides a chest-extendable cardiopulmonary resuscitation bed, including a positioning device 100 and a bed body 200. A top-out area 210 is provided on one side of the top of the bed body 200. The top-out area 210 penetrates the inner wall of the bed body 200. The positioning device 100 is located inside the top-out area 210 and includes a self-top-out mechanism 110.

[0035] The self-ejecting mechanism 110 includes a base slide plate 111. Inner slide rails 112 are fixedly installed at each of the four corners of the top of the base slide plate 111. A support frame 113 is fixedly installed at the center of the top of the base slide plate 111. A worm gear 114 is rotatably connected to the inner wall of the middle section of the support frame 113. A motor 119 is fixedly installed at the bottom of the base slide plate 111, and the output shaft of the motor 119 is fixedly connected to the end wall of the worm gear 114. Drive rods 116 are rotatably connected to both sides of the center line of the top of the base slide plate 111. Two sets of drive rods 116 are each fixedly mounted with a worm gear 115 in the middle. The worm gears 115 are located inside the support frame 113. The two sets of worm gears 115 are located on both sides of the worm 114 and are meshed with the worm 114. Two swing arms 117 are fixedly mounted on the end walls of the drive rods 116. The outer end walls of the four sets of swing arms 117 are rotatably connected to push rods 118. The push rods 118 are located in the corresponding inner slide rails 112 and are connected to the inner wall slide rails of the inner slide rails 112. The tops of the four sets of push rods 118 are fixedly mounted. The assembly plate 120 is equipped with a single mounting plate. Both ends of the mounting plate 120 can be engaged with the pressure plates on both sides of the cardiopulmonary resuscitation (CPR) machine. In this invention, a drive motor 119 drives a worm gear 114 to mesh with two sets of worm wheels 115, thereby driving two sets of drive rods 116 to rotate. This causes the swing arms 117 at both ends of the drive rods 116 to move upward, thereby driving the push rods 118 to move upward within the inner slide rail 112. This causes the four sets of push rods 118 to push the mounting plate 120 upward, lifting the patient's chest cavity away from the bed 200. By engaging the top of the CPR machine into the mounting seat 152 and engaging the pressure plates at both ends with the ends of the mounting plate 120, the CPR machine can perform CPR on the patient's heart and lungs. In particular, during the operation of the CPR machine, the output end of the CPR machine applies pressure to the patient, thereby applying pressure to the mounting plate 120. The cooperation between the worm gear 114 and the worm wheels 115 effectively prevents the mounting plate 120 from shifting downward during the pressure process.

[0036] As one implementation method in this embodiment, such as Figures 7 to 9As shown, slide rails 140 are fixedly installed on both sides of the top of the ejection area 210. A limiting rod 141 is fixedly installed at both ends of the top of the ejection area 210. Screws 142 are rotatably connected to both ends of the center of the top of the ejection area 210. A bottom slide plate 130 is slidably connected to both sets of slide rails 140. The limiting rod 141 slides through the bottom of the bottom slide plate 130. The bottom of the bottom slide plate 130 has a screw hole that engages with the screw 142. A motor 143 is fixedly installed on the outer wall of the ejection area 210, and the output end of the motor 143 is fixedly connected to the end wall of the screw 142. Slide rails 131 are fixedly installed on both sides of the top of the bottom slide plate 130. The bottom of the base slide plate 111 is slidably connected to slide rails 131. A screw rod 142 is rotatably connected to the outer end walls of the bottom slide plate 130. A screw 132 engages with the bottom of a base slide plate 111. A motor 133 is fixedly mounted on the outer wall of the base slide plate 130, and the output shaft of the motor 133 is fixedly connected to the end wall of the screw 132. In this invention, a drive motor 143 drives the screw 142 to engage with the bottom of the base slide plate 130. Under the guidance of the limit rod 141, the base slide plate 130 slides on the slide rail 140, thereby adjusting the position of the base slide plate 130 on the Y-axis. At the same time, the drive motor 133 drives the screw 132 to engage with the bottom of the base slide plate 111, causing the base slide plate 111 to slide on the slide rail 131, thereby adjusting the position of the base slide plate 111 on the X-axis, so that the middle of the assembly plate 120 is aligned with the patient's heart.

[0037] In this embodiment, as Figures 3 to 6As shown, an L-shaped base plate 150 is fixedly installed on the outer wall of the base plate 111. An L-shaped flip plate 151 is rotatably connected to the top of the L-shaped base plate 150 via a hinge. The L-shaped flip plate 151 is located above the bed 200. The maximum flip angle between the L-shaped flip plate 151 and the L-shaped base plate 150 is 90°. The initial included angle between the L-shaped flip plate 151 and the L-shaped base plate 150 is 90°. When not carrying a patient, the L-shaped flip plate 151 is perpendicular to the L-shaped base plate 150. After carrying a patient, the L-shaped flip plate 151 is flipped so that it is aligned with the L-shaped base plate 150. A mounting bracket 152 is provided at the bottom front end of the L-shaped flip plate 151. The inner wall of the mounting bracket 152 can be secured to the top shell of the cardiopulmonary resuscitation machine. The centerline of 52 coincides with the centerline of the assembly plate 120. In this utility model, when transporting a patient during cardiopulmonary resuscitation, the bed 200 shakes continuously during transport, causing the alignment device 100 to bounce. Since the L-shaped base plate 150 is installed together with the base slide plate 111, the L-shaped base plate 150 can always follow the movement when the base slide plate 111 bounces, ensuring that the relative position of the card holder 152 and the assembly plate 120 does not change, thereby maximizing the effectiveness of cardiopulmonary resuscitation. At the same time, the cardiopulmonary resuscitation machine will also cause the bed 200 to vibrate when it is working. Using this device can prevent the cardiopulmonary resuscitation machine from being misaligned with the patient's chest cavity during operation.

[0038] As one implementation method in this embodiment, such as Figures 1 to 5 As shown, a strip-shaped slat 220 is provided on the outer side of the top of the bed body 200. A strip-shaped mating slide 230 is slidably connected to the top of the bed body 200. The strip-shaped mating slide 230 is inserted into the strip-shaped slat 220. The bottom of the strip-shaped mating slide 230 is movably mated with the top of the ejection area 210. In the initial state, the strip-shaped mating slide 230 can close the ejection area 210, thereby protecting the positioning device 100. A wheel slide seat 240 is fixedly installed at the bottom of the bed body 200. The wheel slide seat 240 can move the bed body 200 freely, which is convenient for transferring patients.

[0039] The working principle of the technical solution provided by this utility model is as follows: By pulling the strip-shaped matching slide 230, the strip-shaped matching slide 230 is matched with the strip-shaped slat 220, thereby exposing the positioning device 100. Then, the patient is placed on the bed 200. At this time, the assembly plate 120 does not come into contact with the patient's body.

[0040] The drive motor 143 drives the screw 142 to engage with the bottom of the base slide plate 130. Guided by the limit rod 141, the base slide plate 130 slides on the slide rail 140, thereby adjusting the position of the base slide plate 130 on the Y-axis. Simultaneously, the drive motor 133 drives the screw 132 to engage with the bottom of the base slide plate 111, causing the base slide plate 111 to slide on the slide rail 131, thereby adjusting the position of the base slide plate 111 on the X-axis. This aligns the center of the assembly plate 120 with the patient's heart. At the same time, when the base slide plate 111 moves on the X and Y axes, it can drive the L-shaped base plate 150 to move synchronously. The movement ensures that the position of the card holder 152 is aligned with the heart. At this time, the drive motor 119 drives the worm gear 114 to mesh with the two sets of worm wheels 115, thereby driving the two sets of drive rods 116 to rotate. This causes the swing arms 117 at both ends of the drive rods 116 to move upward, thereby driving the push rods 118 to move upward within the inner slide rail 112. This causes the four sets of push rods 118 to push upward out of the assembly plate 120, pushing the patient's chest cavity away from the bed 200. By inserting the top of the cardiopulmonary resuscitation machine into the card holder 152 and engaging the pressure plates at both ends with the two ends of the assembly plate 120, the cardiopulmonary resuscitation machine can perform cardiopulmonary resuscitation operations on the patient.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model.
