Description

Technical Field

[0001] This utility model relates to the field of cardiopulmonary resuscitation (CPR) machines, and more particularly to a pneumatic CPR machine calibration telescopic support. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) machines are commonly used medical emergency equipment in places such as trains, ambulances, airplanes, and emergency rooms. CPR machines can perform artificial respiration and chest compressions, providing a high level of uninterrupted artificial compression cycle and ventilation support. The principle of CPR machines is to use the reciprocating motion of a piston to achieve uninterrupted compression of the patient's chest, supplemented by intermittent ventilation.

[0003] The pneumatic cardiopulmonary resuscitation (CPR) machine calibration telescopic stand is a specially designed device used to assist in calibrating and adjusting the position and height of the pneumatic CPR machine to ensure that it can perform CPR accurately and stably during use.

[0004] The existing pneumatic cardiopulmonary resuscitation machine calibration telescopic support has the following shortcomings:

[0005] In the calibration of cardiopulmonary resuscitation (CPR) machines, existing calibration devices are mainly applicable to electric resuscitation machines with arm columns. In contrast, pneumatic resuscitation machines do not have arm columns and are directly fixed to the patient with straps during actual use. Since they do not have a supporting frame, operators can only use temporary objects such as boxes as supports to fix the pneumatic resuscitation machine during the calibration process. This temporary alternative method is not only cumbersome and greatly reduces calibration efficiency, but also makes it difficult to guarantee calibration accuracy, resulting in the long-term inability to meet the calibration accuracy of pneumatic CPR machines. Utility Model Content

[0006] This invention provides stable support for the cardiopulmonary resuscitation machine body, avoids equipment shaking during calibration, and effectively improves the accuracy of calibration, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a pneumatic cardiopulmonary resuscitation (CPR) machine calibration telescopic support, including an adjustment mechanism, the bottom of which is fixedly connected to a support mechanism; the adjustment mechanism includes a column, a set of sliders slidably connected to the inner wall of the column, a set of movable plates slidably connected to the inner wall of the sliders, and insert rods fixedly connected to the outer walls of the movable plates; a set of sliding rods fixedly connected to the inner wall of the sliders, a set of compression springs sleeved on the outer walls of the sliding rods; fixing blocks fixedly connected to the outer walls of the column; a connecting rod fixedly connected to the top of the sliders; a set of first connecting plates fixedly connected to the top end face of the connecting rods; and a set of rotating shafts rotatably connected to the inner wall of the first connecting plates. Through these components, the height of the CPR machine body can be quickly and stably adjusted, the adjustment steps are relatively simple, and it is convenient for subsequent uses.

[0008] Preferably, the inner wall of each column is fixedly connected with a limiting rod, the outer wall of the limiting rod is slidably connected to the inner wall of the slider, and the shaft end of the slider is fixedly connected to the outer wall of the movable plate. By setting the limiting rod, the stability of the slider when sliding up and down in the column can be improved, indirectly ensuring that the height adjustment of the first connecting plate is carried out normally.

[0009] Preferably, the outer wall of each fixing block is provided with a circular hole, and the inner wall of the circular hole is slidably connected to the outer wall of the insertion rod. Through the circular hole, the insertion rod can be inserted normally into the appropriate position. Insertion restricts the slider, and the restriction ensures that the first connecting plate can be stably positioned at the specified height.

[0010] Preferably, a set of handles is fixedly connected to the outer wall of the movable plate, one end of the compression spring is fixedly connected to the outer wall of the slider, and the other end of the compression spring is fixedly connected to the outer wall of the movable plate. The handles facilitate the user to pull the movable plate, and simultaneously drive the connected rods to move horizontally, so that a set of rods can be disengaged from the round hole.

[0011] Preferably, the outer wall of the connecting rod is slidably connected to the inner wall of the column, so that the connecting rod can move up and down normally, and the height adjustment of the first connecting plate can be carried out normally.

[0012] Preferably, a set of second connecting plates is fixedly connected to the outer wall of the rotating shaft. A set of circular grooves is opened on the inner wall of the first connecting plate. Movable rods are slidably connected to the inner walls of the circular grooves. The outer walls of the movable rods are fixedly connected to the outer walls of the second connecting plates. By setting the circular grooves and movable rods, the stability of the second connecting plate during rotation can be improved, so that the angle adjustment of the cardiopulmonary resuscitation machine body can be carried out stably.

[0013] Preferably, a set of electric push rods is fixedly installed on the outer wall of the second connecting plate, and a set of clamping plates is fixedly connected to the shaft end of the electric push rods. The cardiopulmonary resuscitation machine body is provided on the opposite side of the two clamping plates. Through the electric push rods and clamping plates, the cardiopulmonary resuscitation machine body can be clamped and fixed to ensure that it can be stably placed on the first connecting plate.

[0014] Preferably, a handle is fixedly connected to the outer wall of one of the rotating shafts, and a set of positioning rods is provided through the outer wall of the handle. Fixing holes are provided on the outer wall of the first connecting plate, and locking blocks are fixedly connected to the outer walls of the positioning rods. The outer walls of the positioning rods and locking blocks are slidably connected to the inner walls of the fixing holes. The handle facilitates the user to rotate one of the rotating shafts, and the positioning rods, locking blocks, and fixing holes restrict the rotation of one of the rotating shafts, allowing subsequent calibration operations to proceed normally.

[0015] Preferably, the support mechanism includes a base, with dampers fixedly installed on the inner wall of the base, and support feet fixedly connected to the shaft ends of the dampers. Springs are sleeved on the outer wall of the dampers. Through the dampers and springs, the overall swaying caused by ground vibration or other external factors can be reduced. In cooperation with the support feet, the overall tilting due to instability of the center of gravity can be effectively prevented, ensuring that the calibration work is carried out safely and smoothly.

[0016] Preferably, an anti-slip pad is fixedly connected to the top of the base, a probe is provided on the top of the anti-slip pad, and a PLC controller is fixedly installed on the top of the base. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, a column is provided, and a limiting rod is installed inside the column. The slider can slide up and down along the limiting rod and is connected to the first connecting plate through a connecting rod. The operator can easily adjust the height of the first connecting plate by simply sliding the slider according to actual needs. After the first connecting plate is adjusted to a suitable height, the slider can be limited by the coordinated action of the fixing block, the round hole, the insert rod, the sliding rod, the compression spring, and the movable plate. When the insert rod is inserted into the round hole of the fixing block, the slider is locked, thereby ensuring that the connecting rod and the first connecting plate are stably at the specified height. This design not only simplifies the adjustment method but also provides stable support for the cardiopulmonary resuscitation machine body, avoiding equipment shaking during calibration and effectively improving the accuracy of calibration.

[0019] 2. In this utility model, by equipping an electric push rod and a clamping plate, the cardiopulmonary resuscitation machine body is stably fixed. When the electric push rod is activated, the clamping plate can automatically adjust the spacing to fit tightly against the cardiopulmonary resuscitation machine, so that the device is stably placed on the first connecting plate. This fixing measure not only avoids displacement or shaking of the device during calibration, but also lays the foundation for subsequent angle adjustment work, ensuring that the adjustment process is carried out smoothly. It is equipped with a rotating shaft, a circular groove, a movable rod, a second connecting plate, a handle, a positioning rod, and a positioning hole to realize flexible adjustment of the angle of the cardiopulmonary resuscitation machine, so that it is in the optimal calibration position.
