Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a flat car with a chest compression platform function. Background Art

[0002] Generally, cardiopulmonary resuscitation is performed by kneeling or standing beside the patient, or by straddling the patient. However, in the actual work of first aid, chest compression operations face many difficulties. For example, medical staff need to perform chest compressions on patients during the transfer of patients. In such cases, medical staff will follow the patient and perform chest compressions on the patient while walking. This operation method increases the difficulty of the medical staff's work and reduces the effect of chest compressions on the patient. For medical staff with insufficient work experience, the patient's transfer will be suspended first, and then chest compressions will be performed on the patient. The first aid method at the cost of stopping movement will prolong the patient's transfer time and thus delay the patient's subsequent treatment. Some medical staff will climb onto the transport flatbed and use a kneeling posture to perform chest compressions on patients during the transfer process, but this method requires medical staff to climb up and down the transport flatbed, which is more laborious and brings a lot of trouble in operation.

[0003] Therefore, the present application provides a flatbed cart with chest compression platform function to meet the needs. Utility Model Content

[0039] like Figures 1 to 10 As shown, an embodiment of the utility model provides a flatbed with an external chest compression platform function, including a flatbed body 1 and a footrest 2, the outer wall of the flatbed body 1 is fixedly connected with a fixing plate 3, the outer wall of the fixing plate 3 is provided with a sliding groove 4, the outer wall of the footrest 2 is fixedly connected with a sliding block 5, the outer wall of the sliding block 5 is slidably connected to the inner wall of the sliding groove 4, and one side of the footrest 2 is fixedly connected with a pulling handle 6. Specifically, the flatbed body 1 has an upper part on which the patient lies and a bracket part below, the footrest 2 is located in the bracket part below, and the footrest 2 is located in the upper position of the flatbed body 1, that is, in the chest position range after the patient lies flat, there are two fixing plates 3 located on both sides of the footrest 2, and the sliding block 5 will not be separated from the sliding groove 4; a supporting component, the supporting component is used to support the footrest 2 to be stable and move synchronously with the flatbed body 1, and the supporting component is connected to the footrest 2; a stabilizing component, the stabilizing component is used to enable medical staff to stand stably on the footrest 2, and the stabilizing component is connected to the footrest 2.

[0040] like Figures 1 to 7As shown, the support assembly includes a support plate 7 fixedly connected to the bottom of the foot pedal 2, the bottom of the support plate 7 is slidably connected to the outer wall of the flat car body 1, the inner wall of the support plate 7 is rotatably connected to a rotating shaft 8, the outer wall of the rotating shaft 8 is fixedly connected to a pop-up plate 9, one side of the pop-up plate 9 is fixedly connected to a moving wheel 10, the inner wall of the support plate 7 is fixedly connected to a rotating torsion spring 11, one end of the rotating torsion spring 11 is fixedly connected to the outer wall of the pop-up plate 9, the inner wall of the support plate 7 is fixedly connected to a limiting spring sheet 12, the limiting spring sheet 12 and the support plate 7 are an integrated structure, and the inner wall of the support plate 7 is opened A moving groove 13 is provided, and a moving block 14 is slidably connected to the inner wall of the moving groove 13, and one end of the moving block 14 is fixedly connected to one end of the limiting spring piece 12. Specifically, the bracket part under the flat car body 1 is provided with a slot for the support plate 7 to pass through, and the height of the bottom of the foot pedal 2 is just the same as the height of the top of the bracket part under the flat car body 1. When the foot pedal 2 is retracted into the flat car body 1, the bottom of the pop-up plate 9 contacts the top of the bracket part under the flat car body 1, and presses against the flat car body 1, so that the rotating torsion spring 11 is in a state of generating torsional force but has no The method drives the pop-up plate 9 to rotate. The rotating torsion spring 11 is a deformable metal material that can generate elastic force. When the pop-up plate 9 is not in contact with the flat car body 1, the torsion force generated by the rotating torsion spring 11 will immediately drive the pop-up plate 9 to rotate. The limiting spring piece 12 is a deformable metal material that can generate elastic force. When the foot pedal 2 is retracted into the flat car body 1, the limiting spring piece 12 is in a stretched state. However, since the vertical part of the L-shaped groove 17 is against the limiting bolt 15 at this time, the limiting spring piece 12 cannot pull the moving block 14 to move. When the pop-up plate 9 rotates, the limiting bolt 15 moves to the L-shaped groove 17. At the inner horizontal position, the elastic force of the limiting spring piece 12 is unable to pull the moving block 14 to move. By setting the supporting assembly, the medical staff can stand on the transport flat car and move synchronously with the transport flat car, and perform chest compressions on the patient during transportation without pausing the patient's transportation, thereby avoiding delaying the patient's subsequent treatment. Since the height of the foot pedal 2 is relatively low, the medical staff does not need to climb up and down the transport flat car time-consuming and laboriously. When the pull handle 6 is pulled to drive the foot pedal 2 to move out, the moving wheel 10 will pop out synchronously, so that it can be operated quickly, thereby improving the rescue speed of the patient.

[0041] like Figures 4 to 7As shown, the outer wall of the moving block 14 is fixedly connected to the limit bolt 15, and the outer wall of the limit bolt 15 is fixedly connected to the toggle plate 16. The outer wall of the pop-up plate 9 is provided with an L-shaped groove 17, and one end of the limit bolt 15 is slidably connected to the inner wall of the L-shaped groove 17. Specifically, the limit bolt 15 will not be separated from the L-shaped groove 17. The L-shaped groove 17 is in the shape of an "L" and is divided into a vertical part and a horizontal part. When the limit bolt 15 is located in the vertical part of the L-shaped groove 17, the pop-up plate 9 can rotate. When the L-shaped groove 17 is in the horizontal part, the pop-up plate 9 cannot rotate. When the foot pedal 2 is retracted into the flat car body 1, the limit bolt 15 is located At one end of the vertical L-shaped groove 17, when the pop-up plate 9 rotates ninety degrees and the moving wheel 10 contacts the ground, the limit bolt 15 is located at one end of the horizontal L-shaped groove 17. Through the L-shaped groove 17, the limit spring 12 and the limit bolt 15 in the supporting assembly, when the pop-up plate 9 rotates ninety degrees, the elastic force of the limit spring 12 drives the limit bolt 15 to move to the groove at the horizontal position in the L-shaped groove 17, and the limit bolt 15 locks the pop-up plate 9 and prevents it from rotating. At this time, the moving wheel 10 just contacts the ground, thereby ensuring the stability of the foot pedal 2 during the movement, so that the medical staff can move smoothly and synchronously with the transfer cart.

[0042] like Figures 8 to 10As shown, the stabilizing component includes a guardrail 18 fixedly connected to the top of the foot pedal 2, a placement groove 19 is provided on the top of the foot pedal 2, the inner wall of the placement groove 19 is rotatably connected to a rotating shaft 20, a stabilizing plate 21 is fixedly connected to the outer wall of the rotating shaft 20, a reset spring 22 is fixedly connected to the bottom of the stabilizing plate 21, the reset spring 22 and the stabilizing plate 21 are an integrated structure, a placement plate 23 is fixedly connected to the bottom of the placement groove 19, a storage groove 24 is provided at the bottom of the placement groove 19, and the inner wall of the storage groove 24 The placement slot 19 is fixedly connected to one end of the reset spring piece 22. Specifically, the placement slot 19 is provided with two for placing the feet, and each foot has two front and rear stable plates 21 and a corresponding rotation axis 20. When the medical staff steps on the stable plate 21, the stable plate 21 will rotate with the rotation axis 20 as the center and squeeze the reset spring piece 22 until the reset spring piece 22 is stored in the storage slot 24. At this time, the lower part of the front and rear stable plates 21 is just parallel to the placement plate 23, that is, the sole of the foot is horizontally stepped on the stable plate 21 and the placement plate 2 The upper parts of the front and rear stabilizing plates 21 are of different shapes. The upper part of the rear stabilizing plate 21 fits the heel of the foot, and the upper part of the front stabilizing plate 21 wraps the front surface of the foot. The part of the stabilizing plate 21 that contacts the foot is made of soft rubber material to ensure comfort. The reset spring piece 22 is a deformable metal material that can generate elastic force. When there is no pressure on the stabilizing plate 21, it will drive the stabilizing plate 21 to rotate, so that the lower part of the stabilizing plate is tilted upward until the upper part of the stabilizing plate does not block the lower part, which is convenient for medical staff to step on. The guardrail 18 is located on both sides of the medical staff to increase the safety during the movement. By setting the stabilizing component, the medical staff can stand stably on the foot pedal 2 and move synchronously with the transfer flat car. The medical staff only needs to stand on the foot pedal 2 with both feet, and the stabilizing plate 21 can fit with the footsteps, which not only avoids the situation that the medical staff stands without asking and falls and gets injured during the movement, but also improves the safety of the medical staff, and there is no need to perform unnecessary operations. The process is simple and fast, which improves the rescue speed of the patient.

[0043] The working principle of the utility model is as follows: the operator pulls the pulling handle 6, and the pulling handle 6 pulls the foot pedal 2 to move outward, and the foot pedal 2 drives the sliding block 5 to slide outward along the inner wall of the sliding groove 4. At the same time, the foot pedal 2 drives the supporting plate 7 to move, and the supporting plate 7 drives the pop-up plate 9 and the moving wheel 10 to move outward at the same time. Because there is no resistance of the flat car body 1 to the pop-up plate 9, the torsional force of the rotating torsion spring 11 drives the pop-up plate 9 to rotate, and the pop-up plate 9 drives the rotating shaft 8 to rotate, and the L-shaped groove 17 on the pop-up plate 9 slides along one end of the limit bolt 15 until the pop-up plate 9 rotates ninety degrees. At this time, due to the elastic force of the limiting spring piece 12, the moving block 14 is driven to slide along the inner wall of the moving groove 13, and the moving block 14 drives the limit bolt 15 to move to the groove at the horizontal position in the L-shaped groove 17, and the limit bolt 15 locks the pop-up plate 9 and cannot rotate. At this time, the moving wheel 10 just contacts the ground, and the medical staff stands on the foot pedal 2 with both feet, and the sole of the foot first connects with a part of the reset spring piece 22 connected to the stabilizing plate 21 The stabilizing plate 21 is touched, so that the stabilizing plate 21 rotates with the rotating shaft 20 as the center, and the reset spring piece 22 is squeezed at the same time, until the reset spring piece 22 is stored in the storage groove 24. At this time, the lower parts of the front and rear stabilizing plates 21 are just parallel to the placement plate 23, that is, the soles of the feet are horizontally stepped on the stabilizing plates 21 and the placement plates 23, and the upper part of the rear stabilizing plate 21 fits the back heel of the foot, and the upper part of the front stabilizing plate 21 wraps the front foot surface of the foot. The guardrails 18 are located on both sides of the medical staff to increase the movement process. For safety, when the foot pedal 2 needs to be folded, the toggle plate 16 is pushed, and the toggle plate 16 drives the limit bolt 15 to move. The limit bolt 15 drives the moving block 14 to slide along the inner wall of the moving groove 13, and the moving groove 13 stretches the limit spring 12 until the limit bolt 15 moves to the vertical position of the L-shaped groove 17. At this time, the pop-up plate 9 can be rotated, and the pop-up plate 9 drives the rotating torsion spring 11 to twist. At the same time, the pop-up plate 9 drives the moving wheel 10 to rotate ninety degrees, and then pushes the foot pedal 2 inward into the flat car body 1.
