Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a transportable composite cardiopulmonary resuscitation pad with newly added abdominal wall fixing straps. Background Art

[0002] When a patient suffers from unexpected cardiac arrest and requires CPR, a CPR pad is often used to provide necessary support and open the patient's airway to prevent obstruction of the patient's lung airway ventilation function. During CPR, the patient is often unconscious and their muscles are relaxed. At this time, the relaxation of the diaphragm will cause the chest pressure applied during CPR to be released by the relaxed diaphragm, resulting in insufficient chest pressure and increased abdominal pressure. Therefore, it is necessary to apply pressure to the abdomen before CPR.

[0003] The current international consensus is that the golden time for treatment after cardiac arrest is only 4 minutes. The commonly used abdominal wall fixation strap is cumbersome to operate, takes a long time, has a high learning cost, and can easily delay rescue time. In addition, the separate fixation straps often appear separately. In emergency rescue, multiple people are required to cooperate in the fixation of the abdominal wall fixation strap and cardiopulmonary resuscitation, which poses many hidden dangers and inconveniences. The above reasons greatly affect the treatment of patients with cardiac arrest.

[0004] After rescuing the patient, he needs to be transferred to an ambulance or other medical facility. In the prior art, the stretcher, CPR pad and abdominal wall fixation strap are separated. Some patients are still very weak after CPR, and it is not suitable for personnel to lift them up and then transfer them to a stretcher.

[0005] Therefore, a device is needed that can be used as a CPR pad, and can also quickly fix the abdominal wall before CPR to provide abdominal pressure. After CPR is completed, there is no need to move the patient, and the pad can be directly converted into a stretcher to reduce secondary injuries caused by patient movement. Summary of the invention

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The transportable composite newly added abdominal wall fixation strap cardiopulmonary resuscitation pad involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] Reference Figure 1-13 The present invention provides a transportable composite cardiopulmonary resuscitation pad with newly added abdominal wall fixation straps, comprising a main board component 1 and a stretcher component 2; the stretcher component 2 is slidably placed in the main board component 1, and the stretcher component 2 is composed of two symmetrical parts, each of which can be rotated outward by 30 degrees; the stretcher component 2 can be up to 200 cm long when extended, and is 70 cm long when fully retracted.

[0036] Specifically, when the heart is compressed after cardiac arrest, muscles throughout the body, especially the diaphragm, will relax. When the heart is compressed, the abdomen will move up and down in the rhythm of the compression. This is because the abdominal pressure is too small, causing the chest pressure to be released during compression, which directly leads to the failure of cardiac compression to achieve the best effect of cardiac arterial blood discharge and venous return of blood to the heart. According to the heart pump mechanism and chest pump mechanism of external cardiac compression, the chest cavity must maintain a certain pressure during cardiac compression.

[0037] In this process, fixing the abdomen with a strap can help reduce or avoid the rise and fall of the abdomen during cardiac compression, thereby increasing the abdominal cavity pressure, which in turn increases the chest cavity pressure during external chest compression, thereby increasing the blood pumping effect and cardiac return effect during cardiac compression. Since the up and down movement of the abdomen is restricted by the abdominal belt, it is easier for us rescue personnel to observe the rise and fall of the chest during artificial ventilation and accurately judge the effectiveness of artificial ventilation.

[0038] In this device, the main board component 1 is the cardiopulmonary resuscitation pad part, which is used to support the patient's chest cavity and fix the abdominal wall. At the same time, the patient's head is tilted back appropriately to keep the airway unobstructed. After cardiopulmonary resuscitation is completed, the stretcher component 2 is pulled out from the main board component 1 to transfer the patient to an ambulance or other treatment location. The whole process is simple and reliable, and the device can be operated proficiently without too much professional training.

[0039] Reference Figure 1-8 The mainboard assembly 1 includes a front lifting frame 11, a plate body 12 fixedly connected to the front lifting frame 11, a neck support 13 fixedly connected to the plate body 12, a headrest area 14 opened on the plate body 12, a lumbar support 15 fixedly connected to the plate body 12, a first ring seat 16 fixedly connected to the side of the lumbar support 15, a first pull ring 17 rotatably connected to the first ring seat 16, and an inelastic belt 18 fixedly connected to the first pull ring 17; the front lifting frame 11 is an upwardly curved structure, the distance between the end of the headrest area 14 and the other end of the plate body 12 is 100 cm, and the width of the plate body 12 is 70 cm.

[0040] Specifically, compared with traditional cardiopulmonary resuscitation pads, the distance between the end of the headrest area 14 and the other end of the board body 12 is 100 cm, and the width of the board body 12 is 70 cm, which makes the upper surface area of ​​the board body 12 larger, which can not only provide effective support for the patient, but also prevent the patient's arms from drooping due to the small pad area when transporting the patient, causing discomfort or secondary injury.

[0041] The end of the front bracket is bent upward, which can prevent the medical staff's hands from being pressed by the bracket when arranging the pad, causing hand injuries or waste of time. The cervical support 13 and the headrest area 14 can support the patient's neck and back of the head area, and the patient's head can be tilted back appropriately, which is helpful to open the airway, expel foreign matter in the airway, reduce airway resistance, and restore normal breathing; the lumbar support 15 supports the patient's waist, fits the physiological curve of the spine, and makes the patient more comfortable; after the patient lies on the board body 12, the lumbar support 15 supports the patient's waist, and at the same time, a section of the inelastic belt 18 is fixed on the first pull ring 17 on one side, and the other end goes around the first pull ring 17 on the other side, and goes back to stick to the middle part of the inelastic belt 18. The inelastic belt 18 has no elasticity and will not be stretched due to the high abdominal pressure. Velcro is attached to the inelastic belt 18, which is convenient for adjustment and adhesion. It is fast to use, low in difficulty, and low in learning cost, which is conducive to rapid rescue by rescue personnel.

[0042] The inelastic belt 18 is printed with a cardiopulmonary resuscitation operation diagram to guide rescuers to perform timely and effective rescue and reduce the probability of casualties of patients.

[0043] Reference Figure 7 The mainboard assembly 1 includes an I-shaped cavity 19 opened inside the board body 12, a central axis column 110 fixedly connected to the middle of the I-shaped cavity 19, an oblique support bar 111 fixedly connected to the upper surface of the I-shaped cavity 19, a limit block 112 fixedly connected to the end of the I-shaped cavity 19, and a rotating shaft 113 fixedly connected to the end of the I-shaped cavity 19.

[0044] Specifically, the board body 12 of the mainboard assembly 1 has a hollow structure inside and adopts a central axis column 110 as the main support. The board body 12 is made of high-density polyethylene blow molding, and the central axis column 110 is made of solid polyethylene material, which has better mechanical properties and provides better supporting effect. The central axis column 110 and the upper surface of the board body 12 adopt a large rounded transition, which is not easy to bend and deform.

[0045] The diagonal support bar 111 is a right-angled trapezoidal prism structure, which cooperates with the stretcher assembly 2 for support. The limit block 112 is used to limit the stretcher assembly 2 to prevent it from rotating at an excessive angle, which may cause difficulty in merging.

[0046] Reference Figure 9-13 The stretcher assembly 2 includes a semicircular head 21 rotatably mounted on the rotating shaft 113, a retaining edge 22 fixed to the side of the semicircular head 21, a damping end 23 fixed to the semicircular head 21, a sliding rod 24 fixed to the damping end 23, a stopper 25 fixed to the end of the sliding rod 24, a first frame plate 26 slidably sleeved on the sliding rod 24, a second frame plate 27 slidably sleeved in the first frame plate 26, and a third frame plate 28 slidably sleeved in the second frame plate 27.

[0047] Specifically, the rotating shaft 113 is at the end of the I-shaped cavity 19, and the limit block 112 is at the edge of the end of the I-shaped cavity 19, and there is a gap between the two. The gap allows the structure formed by the semicircular head 21 and the retaining edge 22 to rotate internally, and when the retaining edge 22 contacts the limit block 112, the angle between the axis of the sliding rod 24 and the edge of the plate body 12 is 30 degrees.

[0048] The first frame plate 26 is slidably sleeved on the slide rod 24. After the slide rod 24 rotates outward by 30 degrees, the end of the first frame plate 26 away from the headrest area 14 will still be slidably connected to the lower surface inside the I-shaped cavity 19, thereby limiting the movement range of the first frame plate 26 and preventing the first frame plate 26 from rotating too much and causing difficulty in recovery.

[0049] Reference Figure 9-10 The stretcher assembly 2 includes a primary cavity 29 opened inside the first frame plate 26, a thick tube 210 opened on one side of the first frame plate 26, a bayonet 211 arranged at one end of the thick tube 210, a leg fixing seat 212 fixedly connected to the outer surface of the first frame plate 26, an elliptical ring 213 rotatably connected to the leg fixing seat 212, a leg strap 214 wound and fixed on the elliptical ring 213, and a secondary cavity 215 opened inside the second frame plate 27; the second frame plate 27 is slidably connected in the primary cavity 29; the primary cavity 29 is in the shape of a triangular pyramid, and the end surface close to the headrest area 14 is larger than the end surface close to the waist support 15; the second frame plate 27 is a triangular pyramid structure, and the size of the end surfaces on both sides of the second frame plate 27 corresponds to the primary cavity 29; the end surface area of ​​the primary cavity 29 close to the headrest area 14 is smaller than the end surface area of ​​the second frame plate 27 close to the waist support 15.

[0050] Specifically, the main-stage cavity 29 is a triangular pyramid structure, and the second frame plate 27 is also a triangular pyramid structure. Since the end surface area of ​​the main-stage cavity 29 close to the lumbar support 15 is smaller than the end surface area of ​​the second frame plate 27 close to the headrest area 14, when the second frame plate 27 slides in the main-stage cavity 29, it will not separate from the main-stage cavity 29, and can slide along the main-stage cavity 29 to extend the stretcher assembly 2. When the second frame plate 27 slides to the maximum position, it is locked by the end surface of the main-stage cavity 29 close to the lumbar support 15 to achieve fixation.

[0051] The leg fixing seat, the elliptical ring 213 and the leg strap 214 fixedly connected to the outer surface of the first frame plate 26 have the following functions: after the cardiopulmonary resuscitation of the patient is completed, the patient's legs are fixed on the first frame plate 26 to prevent the patient's legs from shaking during the transportation process and causing secondary injuries; wherein, the leg strap 214 is of detachable design, and can be used to fix the patient's legs when needed, and can be removed for use when not needed.

[0052] The diameters of the thick cylinder 210, the stopper 25 and the damping end 23 are close. When the slide rod 24 slides in the thick cylinder 210, the slide rod 24 is limited at the center of the thick cylinder 210 by the bayonet 211. At the same time, the stopper 25 slides in the thick cylinder 210 and performs secondary limiting, so that the slide rod 24 can move on the central axis of the thick cylinder 210. When the first frame plate 26 moves outward along the slide rod 24, the bayonet 211 gradually approaches the stopper 25, and when the bayonet 211 contacts the stopper 25, the first frame plate 26 moves to the maximum position; when the first frame plate 26 is recovered, the damping end 23 gradually approaches the bayonet 211 and finally contacts the bayonet 211 to limit the first frame plate 26.

[0053] Reference Figure 12-13 The stretcher assembly 2 includes a rear lifting frame 216 fixedly connected to the third frame plate 28, a thread 217 provided on the rear lifting frame 216, a connecting tube 218 screwed on the thread 217, a female end interface 219 provided at the end of the connecting tube 218, an embedding groove 220 provided on the female end interface 219, a male head 221 fixedly connected to the rear lifting frame 216, and a fixed ball 222 fixedly connected to the male head 221; the third frame plate 28 is slidably connected in the secondary cavity 215, the secondary cavity 215 and the third frame plate 28 are both triangular prism structures, and the end surface area of ​​the secondary cavity 215 close to the first frame plate 26 is larger than the end surface area away from the first frame plate 26; the end surface areas of the two ends of the third frame plate 28 correspond to the secondary cavity 215, and the end surface area of ​​the third frame plate 28 close to the first frame plate 26 is larger than the end surface area of ​​the secondary cavity 215 away from the first frame plate 26.

[0054] Specifically, a rear lifting frame 216 is fixed on the third frame plate 28, and the rear lifting frame 216 is divided into a left side and a right side. After the patient's cardiopulmonary resuscitation is completed, the left and right sides of the rear lifting frame 216 are pulled apart. Since a connecting tube 218 with a thread 217 on one side and a female interface 219 on the other side is adopted, the left and right sides are easy to connect or separate, and have a high bending strength when connected.

[0055] After the two sides of the rear lifting frame 216 are pulled open, the angles of the two sides of the stretcher assembly 2 continue to be opened until the retaining edge 22 contacts the limit block 112, and the opening angle of the stretcher assembly 2 reaches plus or minus 30 degrees. At this time, the rear lifting frame 216 is pulled along the direction of the slide bar 24, and the first frame plate 26, the second frame plate 27 and the third frame plate 28 are all pulled to the maximum position. At this time, the maximum distance between the headrest area 14 and the end of the third frame plate 28 reaches two meters, which meets the height requirements of most people.

[0056] Since the first frame plate 26 is limited by the lower surface inside the I-shaped cavity 19 when it is rotated to the maximum position, the first frame plate 26 cannot rotate at will; then the rear lifting frame 216 is pulled closer to the middle, and the patient's side position needs to be slightly lifted during the process, so that the wedge-shaped surfaces of the first frame plate 26, the second frame plate 27 and the third frame plate 28 can be inserted into the gap between the patient's torso and the ground; after the wedge-shaped surfaces on both sides are inserted into the gap between the patient's torso and the ground, the male head 221 is inserted into the female end interface 219, and after the fixing ball 222 is embedded in the embedding groove 220, the stretcher is formed; at this time, the leg straps 214 are used or the inelastic belt 18 is released as needed.

[0057] During use, the board body 12, neck support 13 and waist support 15 on the main board assembly 1 provide an optimized support structure to ensure stability during cardiopulmonary resuscitation operations, and the waist support 15, the first ring seat 16, the first pull ring 17 and the inelastic belt 18 fix the abdomen to enhance the cardiopulmonary resuscitation effect and help improve the success rate of cardiopulmonary resuscitation. At the same time, its design allows for the use of the first frame board 26, the second frame board 27 and the third frame board 28 as a temporary stretcher after successful resuscitation to facilitate patient transfer.

[0058] By redesigning the CPR pad, the deformation transition of the plate body 12 to the stretcher is simple and reliable. The device is easy to operate, and both medical staff and ordinary people can quickly get started and perform effective CPR operations. The CPR operation diagram on the inelastic belt 18 can assist the user to accurately position the palm for chest compression and maintain a correct posture, which can significantly improve the patient's survival rate.

[0059] The working principle of the present invention is as described above and is applicable to any one of the above.
