Description

Technical Field

[0001] This invention belongs to the field of emergency medical auxiliary equipment technology, and in particular relates to an auxiliary device for rescuers with insufficient arm length to perform the Heimlich maneuver. Background Technology

[0002] Airway obstruction is a common emergency worldwide, which can lead to death from asphyxiation due to lack of oxygen within a short period of time. Children and the elderly are the most vulnerable groups. The Heimlich maneuver, as the core technique for dealing with complete airway obstruction, involves applying a rapid inward and upward thrust to the patient's upper abdomen. This uses the residual air in the chest cavity to create an airflow that expels the foreign object. Since its invention, this first aid method has saved millions of lives. The principle of operation is as follows: the rescuer hugs the patient's waist, makes a fist and places it two finger widths above the navel, wraps the fist with the other hand and quickly thrusts into the abdomen, forcing the diaphragm to rise and increasing the pressure in the chest cavity, thereby expelling the foreign object.

[0003] However, the effectiveness and safety of the Heimlich maneuver are highly dependent on the rescuer's physical condition. First, the rescuer must be able to hug the patient from behind. If the patient is obese, or the rescuer is too short (such as a teenager rescuing an adult) or has too short arms, the rescuer may not be able to accurately place their fist at the position "two finger widths above the navel", making it impossible to perform the rescue, or the direction and position of the impact may be incorrect, affecting the rescue effect, or even causing secondary injury to the patient. Therefore, a Heimlich maneuver auxiliary device was designed to address the above situations. Summary of the Invention

[0004] The purpose of this invention is to provide a force-applying component and a squeezing component that are slidably connected to the chest protector. The force-applying component can compensate for the problem of insufficient arm length of the rescuer, while the squeezing component can accurately position the squeezing position, thereby enabling the rescuer to accurately, safely and efficiently rescue the patient. This solves the problem in the background art where, if the patient is obese, or the rescuer is too short (such as a teenager rescuing an adult) or has too short arms, the rescuer may not be able to accurately place their fist at the position "two finger widths above the navel", resulting in the inability to perform rescue, or the direction and position of the impact during rescue may be incorrect, affecting the rescue effect, or even causing secondary injury to the patient.

[0005] The specific technical solution of the present invention is as follows: A Heimlich maneuver assist device includes a chest protector with an arc-shaped cross-section. The front of the chest protector has a support member adapted to the human ribcage. Elastic bands are connected to the left and right sides of the chest protector, and the two elastic bands are connected and disconnected via a connecting mechanism. An operating part is slidably connected to the chest protector in a front-rear direction. The operating part is located below the support member and includes a compression member that contacts the human body. The compression member is connected to a force-applying member located on the front side of the chest protector. The force-applying member has handles on its left and right sides for gripping, and its cross-section is arc-shaped.

[0006] Furthermore, the top of the support piece has arc-shaped concave surfaces on both sides that are adapted to the rib arches on both sides of the human body, and an arc-shaped protrusion in the middle of the top of the support piece, with the apex of the arc-shaped protrusion being lower than the upper surface of the chest protector.

[0007] Furthermore, the support component is made of silicone rubber, and a protective pad is provided on the front facade of the chest protector, which is also made of silicone rubber.

[0008] Furthermore, the connecting mechanism is a Velcro, including a hook side and a loop side. The hook side is located on the inner surface of an elastic band, and the loop side is located on the outer surface of another elastic band. The elastic band is made of nylon spandex elastic band. The hook side and the loop side are fixed to the elastic band by a sewing process.

[0009] Furthermore, the chest protector has several through holes located below the support member. The through holes penetrate the front and rear surfaces of the chest protector and are equipped with sliding rods. The two ends of the sliding rods are connected to the pressing member and the force-applying member, respectively. The operating part achieves a sliding connection with the chest protector through the sliding fit between the through holes and the sliding rods.

[0010] Furthermore, a limiting component is fixedly sleeved on the slide rod. The longitudinal section of the limiting component is annular, and the circumferential surface of the limiting component fits against the inner surface of the through hole. Blocking components are provided at both ends of the through hole. A sliding hole adapted to the slide rod is provided in the center of the blocking component. A spring is provided between the limiting component and the blocking component.

[0011] Furthermore, the front facade of the extruded part is provided with a buffer. The front facade of the buffer is an arc-shaped convex surface, and the apex of the arc-shaped convex surface is located at the center of the buffer. The buffer is made of hard silicone.

[0012] Furthermore, the front face of the force-applying component has several sliding holes II that are adapted to the sliding rod. The rear end of the sliding holes II has an adjustment hole that penetrates the rear face of the force-applying component. An adjustment knob is rotatably connected inside the adjustment hole. The adjustment knob has a circular cross-section. A positioning component is fixedly fitted on the outer circumference of the adjustment knob. A positioning groove matching the positioning component is provided on the inner circumference of the adjustment hole. The adjustment knob achieves a rotatable connection with the force-applying component through the sliding fit between the positioning component and the positioning groove. The inner circumference of the adjustment knob has an internal thread. The rear end of the sliding rod has an external thread matching the internal thread. The adjustment knob achieves a threaded connection with the sliding rod through the threaded fit between the internal and external threads.

[0013] Furthermore, extensions are slidably connected to both sides of the force-applying component, and handles are provided on the extensions, with the top of the handles tilted inwards.

[0014] Furthermore, several extension rods are vertically arranged on one side of the extension member. The extension rods have an arc that matches the force-applying component. The force-applying component has a sliding groove inside that matches the extension rods. The sliding groove runs through both sides of the extension member. The extension member achieves a sliding connection with the force-applying component through the sliding fit between the extension rods and the sliding groove. A clearance groove is provided at the top of the uppermost sliding groove. The upper surface of the extension rod that matches the uppermost sliding groove has a threaded rod that matches the clearance groove. The threaded rod is equipped with a positioning nut.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the rescuer is preparing to provide assistance to the patient, they only need to use the elastic band to secure the auxiliary device to the patient's upper abdomen and place the support against the patient's ribcage. After accurate positioning, the rescuer should grasp the force application device with both hands through the handles and pull it backward quickly and repeatedly. The compression device will then deliver multiple impacts to the patient's abdomen until the rescue is completed. The force application device extends the rescuer's arms, effectively compensating for insufficient arm length. The support device allows for accurate positioning of the patient's upper abdomen, and the compression device delivers multiple impacts to the patient's upper abdomen, improving the accuracy of the rescue location, enhancing the rescue effect, and avoiding secondary injuries to the patient during the rescue.

[0016] 2. By turning the adjustment knob, the position of the force-applying component on the slide rod can be positioned, and the distance between the squeezing component and the force-applying component can be controlled. This allows for adjustment of the squeezing depth of the squeezing component on the patient's upper abdomen to accommodate patients with different upper abdominal fat thicknesses, improving the emergency treatment effect and enhancing the practicality and applicability of the emergency aid device.

[0017] 3. By sliding the force-applying component and the extension component, and fixing the position of the extension component with the positioning nut, the force-applying component can be extended to both sides to accommodate rescuers with different arm spans, enabling them to find the best rescue position, improving the emergency rescue effect, and also enhancing the practicality and applicability of the emergency rescue auxiliary device.

[0019] To better understand the purpose, structure, and function of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0021] See Figures 1 to 8This embodiment discloses a Heimlich maneuver aid, including a chest protector 1. The chest protector 1 has an arc-shaped cross-section, allowing it to fit snugly against the human chest. This close contact allows the impact force to be diffused to the ribs, releasing the force and preventing damage to the lowest ribs during the impact. The front surface of the chest protector 1 has a support member 11 adapted to the ribcage. When using the aid, the support member 11 is placed on the patient's upper abdomen, pressing against the lowest ribs on both sides for accurate positioning. Elastic bands 2 are connected to the left and right sides of the chest protector 1. The two elastic bands 2 are connected and disconnected via a connecting mechanism, securing the aid to the patient's upper abdomen and preventing damage during the rescue process due to impact. The impact force causes the position to shift, affecting the rescue effect; the chest protector 1 is slidably connected to the operating part, which is slidably connected to the chest protector 1 in the front and back direction. The operating part is located below the support 11. The operating part includes a squeezing part 41 that comes into contact with the human body. The squeezing part 41 is connected to a force-applying part 42, which is located on the front side of the chest protector 1. The left and right sides of the force-applying part 42 are respectively provided with handles 431 for gripping. The rescuer grips the force-applying part 42 with both hands through the handles 431 and pulls it backward quickly several times. The squeezing part 41 impacts the patient's abdomen multiple times until the rescue is completed. The force-applying part 42 extends the rescuer's arms, effectively compensating for the problem of insufficient arm length. The cross-section of the force-applying part 42 is arc-shaped. The arc-shaped force-applying part 42 enables the rescuer with insufficient arm length to achieve the effect of hugging the patient.

[0022] The top of the support member 11 has arc-shaped concave surfaces 111 on both sides that are adapted to the rib arches on both sides of the human body. When the auxiliary device is in use, the arc-shaped concave surfaces 111 abut against the rib arches on both sides of the patient. In this way, the compression member 41 located below the support member 11 can accurately fit against the upper abdomen of the patient. When impacting the upper abdomen of the patient, the rib arches on both sides of the patient can limit the auxiliary device through the arc-shaped concave surfaces 111, preventing the auxiliary device from sliding upward during the impact, causing the impact position to deviate and causing secondary injury to the patient. The top of the support member 11 has an arc-shaped protrusion 112 in the middle. The arc-shaped protrusion 112 can be locked between the rib arches on both sides of the patient, further preventing the auxiliary device from sliding upward during the impact. The apex of the arc-shaped protrusion 112 is lower than the upper surface of the chest protector 1, so that the arc-shaped protrusion 112 can avoid the xiphoid process of the patient, preventing the support member 11 from touching the xiphoid process of the patient during the impact and causing secondary injury.

[0023] The support component 11 is made of silicone rubber, and the front face of the chest protector 1 is provided with a protective pad 12. The protective pad 12 is made of silicone rubber. Silicone rubber has a high elastic recovery rate, which takes into account both soft touch and structural support. It can protect the patient's ribs and also realize the support and positioning function of the auxiliary device.

[0024] The connecting mechanism is Velcro, including a hook side 31 and a rough side 32. The hook side 31 is located on the inner surface of one elastic band 2, and the rough side 32 is located on the outer surface of another elastic band 2. Velcro can be opened and closed quickly, which improves the speed of rescue and the success rate of first aid. Velcro is also sturdy and durable, unlike zippers or buckles, which cannot be used when a single part is damaged. Velcro is soft and safe as a whole and has a high degree of conformity to the human body. The elastic band 2 is made of nylon spandex elastic band, and the hook side 31 and the rough side 32 are fixed to the elastic band 2 by sewing.

[0025] The chest protector 1 has several through holes 13, which are located below the support member 11. The through holes 13 penetrate the front and rear surfaces of the chest protector 1. A sliding rod 44 is installed inside the through hole 13. The two ends of the sliding rod 44 are connected to the squeezing member 41 and the force-applying member 42, respectively. The operating part is slidably connected to the chest protector 1 through the sliding cooperation between the through hole 13 and the sliding rod 44. In this embodiment, there are two through holes 13, which are arranged opposite to each other on the left and right sides near the chest protector 1. It can be further optimized that the through holes 13 have an upward tilt angle, so that when the rescuer pulls the force-applying member 42, the squeezing member 41 can generate an inward and upward impact on the patient's upper abdomen, which further improves the rescue effect.

[0026] A limiting member 441 is fixedly sleeved on the sliding rod 44. The longitudinal section of the limiting member 441 is annular. The circumferential surface of the limiting member 441 fits against the inner surface of the through hole 13. The front and rear ends of the through hole 13 are respectively provided with blocking members. The center of the blocking member is provided with a sliding hole 131 that is adapted to the sliding rod 44. A spring 442 is provided between the limiting member 441 and the blocking member. In this embodiment, a spring 442 is provided between the front surface of the limiting member 441 and the rear surface of the blocking member located in front of it. When the rescuer holds the force-applying member 42 and completes one impact on the patient's upper abdomen, the force-applying member 42 is reset by the elastic force of the spring 442, preparing for the rescuer to perform the next impact action.

[0027] The front face of the extrusion component 41 is equipped with a buffer component 411. The front face of the buffer component 411 is an arc-shaped convex surface. The apex of the arc-shaped convex surface is located at the center of the buffer component 411. The design of the arc-shaped convex surface can concentrate the force point in a specific area of ​​the upper abdomen, forming an impact fulcrum, focusing the pressure transmission, avoiding the dispersion of impact force and affecting the rescue effect. The buffer component 411 is made of hard silicone, which has a certain strength. It can withstand the impact force during rescue without deformation, and will not cause rigid collision injuries to the human skin, thus improving the rescue effect and safety and avoiding secondary injuries.

[0028] The front surface of the force-applying component 42 has several sliding holes 421 that fit the slide rod 44. The rear end of each sliding hole 421 has an adjustment hole 422 that penetrates the rear surface of the force-applying component 42. An adjustment knob 45 is rotatably connected within the adjustment hole 422. The adjustment knob 45 has an annular cross-section. A positioning element 451 is fixedly fitted onto the outer circumferential surface of the adjustment knob 45. The inner circumferential surface of the adjustment hole 422 has a positioning groove 4221 that matches the positioning element 451. The adjustment knob 45 achieves a rotatable connection with the force-applying component 42 through the sliding engagement of the positioning element 451 and the positioning groove 4221. The inner circumferential surface of the adjustment knob 45 has an internal thread, and the rear end of the slide rod 44 has a thread that matches the internal thread. The external thread of the adjusting knob 45 allows it to be threadedly connected to the slide rod 44 through the threaded engagement of the internal and external threads. During use, by turning the adjusting knob 45, the position of the force-applying component 42 on the slide rod 44 can be positioned, and the distance between the squeezing component 41 and the force-applying component 42 can be controlled. This allows for adjustment of the squeezing depth of the squeezing component 41 on the patient's upper abdomen to accommodate patients with different upper abdominal fat thicknesses, improving the emergency treatment effect and enhancing the practicality and applicability of the emergency aid device. Further optimization is possible by providing anti-slip texture on the outer circumference of the adjusting knob 45 to increase the friction between the outer circumference of the adjusting knob 45 and the operator's hand, making it easier for the operator to turn the adjusting knob 45.

[0029] The force-applying component 42 is slidably connected to extensions 43 on both sides. Each extension 43 has a handle 431. When the rescuer grasps the extensions 43 on both sides with both hands through the handles 431, the top of the handles 431 is tilted inward. When the hand grasps the handles 431 and applies a backward pulling force, the pulling force is not collinear with the axis of the handles 431 due to the tilt of the handles 431, forming an angle. This forces the rescuer's arm to generate a backward and upward force, which meets the requirement of the direction of the impact force in the Heimlich maneuver and improves the rescue effect.

[0030] Several extension rods 432 are vertically arranged on one side of the extension member 43. The extension rods 432 have an arc adapted to the force-applying member 42. The force-applying member 42 has a sliding groove 423 inside that matches the extension rods 432. The sliding groove 423 penetrates both sides of the extension member 43. The extension member 43 achieves a sliding connection with the force-applying member 42 through the sliding engagement of the extension rods 432 and the sliding groove 423. A clearance groove 424 is opened at the top of the uppermost sliding groove 423. The upper surface of the extension rod 432 that matches the uppermost sliding groove 423 has a threaded rod 433 that matches the clearance groove 424. A positioning nut 46 is provided. Through the sliding connection between the force-applying member 42 and the extension member 43, the extension rod 432 is pulled to a suitable length. Tightening the positioning nut 46 causes the lower surface of the positioning nut 46 to press against the upper surface of the force-applying member 42, thereby fixing the position of the extension rod 432. This allows the force-applying member 42 to extend its length to both sides to accommodate rescuers with different arm spans, enabling them to find the optimal rescue position. This improves the effectiveness of emergency rescue and enhances the practicality and applicability of the emergency rescue auxiliary device. Further optimization could be achieved by using a wing nut for easy tightening.

[0031] Working principle: When using the auxiliary device, first pull the extension rod 432 to a suitable length, tighten the positioning nut 46 to fix the position of the extension rod 432, and tighten the adjustment knob 45 to adjust the compression depth of the compression member 41 on the patient's upper abdomen. The auxiliary device is then secured to the patient's upper abdomen by two elastic bands 2. The rescuer grips the force application member 42 with both hands through the handle 431 and pulls it backward quickly and repeatedly. The compression member 41 applies multiple impacts to the patient's abdomen until the rescue is completed. The force application member 42 extends the rescuer's arms, effectively compensating for the problem of insufficient arm length.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
