Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable cardiopulmonary resuscitation device. Background Art

[0002] In first aid, a portable cardiopulmonary resuscitation device is an indispensable first aid tool. When an emergency such as cardiac arrest occurs, timely cardiopulmonary resuscitation is crucial to saving the patient's life. Due to the complex and changeable first aid environment, a portable cardiopulmonary resuscitation device is lightweight and easy to carry, so it can be quickly brought to the patient by first aid personnel to provide timely resuscitation support for the patient.

[0003] In the prior art, a Chinese patent document with publication number CN212466552U proposes a portable electric cardiopulmonary resuscitation device. The application directly places the resuscitation device above the patient, and adjusts the position up and down and left and right to make the pressing mechanism correspond to the patient's cardiac resuscitation position. There is no need to move the patient, thereby avoiding and reducing the harm to the patient caused by moving. What is consistent with the prior art in the above patent document is that when the cardiopulmonary resuscitation device is used on an inclined support surface, the cardiopulmonary resuscitation device as a whole will also be skewed. However, the height adjustment structure in the above document can only adjust the height of the presser on the cardiopulmonary resuscitation device, and cannot adjust the angle of the presser. When the skew angle is too large, pressing may cause secondary injury to the patient. Furthermore, we disclose a portable cardiopulmonary resuscitation device to meet the actual demand for traditional portable cardiopulmonary resuscitation devices that may cause secondary injury to the patient when the presser is pressed at a skew angle with the patient that is too large. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a portable cardiopulmonary resuscitation device to solve the problem that when the traditional portable cardiopulmonary resuscitation device presses at an angle that is too large between the compressor and the patient's body, the patient may suffer secondary injuries.

[0005] Based on the above-mentioned purpose, the utility model provides a portable cardiopulmonary resuscitation device, including a square plate, a presser for cardiopulmonary resuscitation is arranged in the middle of the square plate, open grooves are opened on the outer walls of the four sides of the square plate, and the interiors of multiple open grooves are rotatably connected to a rotating rod through a damping shaft, a support height adjustment component is arranged at one end of the rotating rod, and the support height adjustment component includes a vertically arranged threaded column, and the threaded column is threadedly connected to the rotating rod, both sides of the lower end surface of the square plate are rotatably connected to a fitting plate, and both sides of the middle part of the square plate are provided with adjustment components for rotating the fitting plate, and the adjustment component includes an adjustment rod threadedly connected to the square plate, and the lower end of the adjustment rod is slidably connected to the fitting plate.

[0006] Preferably, a sphere is fixedly connected to the lower end of the threaded column, and a ball head support seat is rotatably connected to the outside of the lower end of the sphere.

[0007] Preferably, a level gauge is provided at the middle of the upper end surface of the presser.

[0008] Preferably, a first rotating shaft is fixedly connected to the middle part of one side of the upper end surface of the two bonding plates, and the bonding plates are rotatably connected to the square plate via the first rotating shaft.

[0009] Preferably, a slide groove is provided in the middle of the upper end surface of the bonding plate, a slider is slidably connected inside the slide groove, the lower end of the adjustment rod is rotatably connected to the slider via a second rotating shaft, and the bonding plate is of arc-shaped design.

[0010] Preferably, handles are fixedly connected to both sides of the middle portion of the upper end surface of the square plate.

[0011] The beneficial effects of the utility model are as follows: when the cardiopulmonary resuscitation device is in use, when the supporting surface is inclined, the support heights of the four sides of the square plate can be adjusted through the provided height adjustment assembly. When the height of one corner of the square plate is too high, the corresponding threaded column is rotated to make the threaded column rise along the rotating rod, so that the height of the corresponding corner that is too high is lowered, and the horizontal level meter on the presser is used for correction, so that the pressing angle of the presser on the square plate can be kept perpendicular to the patient's body, reducing the possibility of secondary injury to the patient caused by excessive tilt of the presser. The rotatable connection between the ball head support seat and the threaded column increases the contact area between the ball head support seat and the inclined ground, and the medical staff's hand pressing handle during use increases the stability of the cardiopulmonary resuscitation device. In addition, fitting plates are rotatably connected to both sides of the lower end of the square plate, and an adjustment assembly is provided on the upper end of the fitting plate. The rotation angle of the fitting plate can be adjusted by the provided adjustment assembly, thereby adapting to patients of different body sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 4As shown, a portable cardiopulmonary resuscitation instrument comprises a square plate 1, a compressor 4 for cardiopulmonary resuscitation is arranged in the middle of the square plate 1, opening grooves 6 are opened on the outer walls of the four sides of the square plate 1, and the interiors of the plurality of opening grooves 6 are rotatably connected to a rotating rod 7 through a damping rotating shaft, and a support height adjustment component is arranged at one end of the rotating rod 7, and the support height adjustment component comprises a vertically arranged threaded column 8, and the threaded column 8 is threadedly connected to the rotating rod 7, and both sides of the lower end surface of the square plate 1 are rotatably connected to a bonding plate 9, and both sides of the middle part of the square plate 1 are provided with an adjustment component for rotating the bonding plate 9, and the adjustment component comprises an adjustment rod 5 threadedly connected to the square plate 1, The lower end of the adjusting rod 5 is slidably connected to the fitting plate 9. When the cardiopulmonary resuscitation device is in use, when the supporting surface is tilted, the supporting height of the four sides of the square plate 1 can be adjusted through the provided height adjustment component, so that the pressing angle of the presser 4 on the square plate 1 can be kept perpendicular to the patient's body, reducing the possibility of the patient suffering secondary injury due to the excessive tilt of the presser 4. In addition, fitting plates 9 are rotatably connected to both sides of the lower end of the square plate 1, and an adjusting component is provided at the upper end of the fitting plate 9. The rotating angle of the fitting plate 9 can be adjusted by the provided adjusting component to adapt to patients of different body sizes.

[0022] Further, such as Figure 1 and Figure 3 As shown, the lower end of the threaded column 8 is fixedly connected to a sphere 15, and the lower end of the sphere 15 is rotatably connected to a ball head support seat 14. A level meter 3 is provided in the middle of the upper end surface of the presser 4, and handles 2 are fixedly connected on both sides of the middle of the upper end surface of the square plate 1. When the support surface is inclined and the horizontal angle of the square plate 1 needs to be adjusted, the threaded column 8 is rotated to make the threaded column 8 rise and fall on the rotating rod 7, thereby realizing the adjustment of the support height, and by observing the level meter 3 on the presser 4, it can be checked whether the square plate 1 remains horizontal, and then the angle between the presser 4 and the patient's body can be adjusted. When the presser 4 is pressing, the medical staff holds the handle 2 to improve the stability of the cardiopulmonary resuscitation instrument.

[0023] Further, such as Figure 2 and Figure 4As shown, a first rotating shaft 10 is fixedly connected to the middle part of one side of the upper end surface of the two bonding plates 9, and the bonding plates 9 are rotatably connected to the square plate 1 through the first rotating shaft 10. A sliding groove 11 is provided in the middle part of the upper end surface of the bonding plate 9, and a slider 12 is slidably connected inside the sliding groove 11. The lower end of the adjusting rod 5 is rotatably connected to the slider 12 through the second rotating shaft 13. The bonding plate 9 is designed to be arc-shaped. When the angle of the bonding plate 9 needs to be adjusted, the adjusting rod 5 is rotated to make the adjusting rod 5 rise and fall on the square plate 1. Since one end of the bonding plate 9 is rotatably connected to the square plate 1, when the adjusting rod 5 is lifted and lowered, the slider 12 at the lower end of the adjusting rod 5 will slide in the sliding groove 11 and then drive the bonding plate 9 to rotate, thereby adapting to patients of different body shapes. Through this structural design, the stability of the patient's body when the cardiopulmonary resuscitation device is pressed is greatly improved.
