Abstract
Description
Technical Field
[0001] This invention relates to the field of medical emergency equipment technology, specifically to a mechanical device for assisting in the implementation of the abdominal thrust maneuver (i.e., the Heimlich maneuver) to relieve airway obstruction by foreign objects. Background Technology
[0002] Acute choking is a life-threatening medical emergency. The internationally recognized first-line first aid measure is the Heimlich Maneuver, whose core principle is to apply an inward and upward thrust to the patient's upper abdomen, thereby raising the diaphragm, increasing intrathoracic pressure, and using the residual airflow in the lungs to expel the foreign object from the airway.
[0003] However, in practical application, performing the Heimlich maneuver manually has many limitations: First, for the frail, elderly, or untrained rescuers, it is often difficult to generate sufficient instantaneous force to expel stubborn foreign objects; second, in a state of emergency panic, rescuers are prone to misaligning their pressure points (such as pressing on the ribs or xiphoid process), leading to rib fractures or internal organ damage and failing to generate effective airflow; finally, when a choking patient is alone, the traditional self-rescue method is to use the back of a chair to thrust into the abdomen, but in modern homes, due to the prevalence of upholstered furniture, there is often a lack of a firm and appropriately sized point of leverage, resulting in a low success rate of self-rescue. Therefore, there is an urgent need for an auxiliary device that can amplify the force application, standardize the pressure point, and combine self-rescue and mutual rescue functions. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an abdominal emergency push device, which aims to solve the problems of insufficient force, inaccurate pressure positioning, and difficulty in self-rescue by a single person in existing manual first aid.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an abdominal emergency rescue pushing device, comprising: a rigid main plate having a first surface facing the abdomen of the human body, a second surface facing away from the human body, and a bottom edge located at the lower end of the rigid main plate; a pair of grip handles respectively disposed on the left and right sides of the rigid main plate, configured for gripping and applying force with both hands; a pressure protrusion disposed in the central area of the first surface, protruding outward from the first surface to form a vertex; and a fulcrum abutment extending along the bottom edge, having an arcuate contour suitable for abutting against the lower abdomen or pelvic region of the human body; wherein, the rigid main plate, grip handles, pressure protrusion, and fulcrum abutment are integrally connected structures, and the vertical distance from the vertex of the pressure protrusion to the first surface is configured such that: when the fulcrum abutment abuts against the lower abdomen or pelvic region of the human body and the grip handle is subjected to a downward external force, the rigid main plate can rotate with the fulcrum abutment as a physical fulcrum, thereby driving the pressure protrusion to move along an inward and upward trajectory.
[0006] As a preferred embodiment of the present invention, the pressure protrusion is hemispherical, ellipsoidal or frustum-shaped, and its surface is covered with a first flexible buffer layer. The hardness of the first flexible buffer layer is lower than that of the rigid main body plate. This arrangement, through a combination of soft and hard structure, simulates the force application point of a human fist while using the flexible layer to disperse contact stress, thereby reducing physical damage to the abdominal soft tissue.
[0007] In addition, the rigid main body plate has a kidney-shaped or crescent-shaped curved structure in the top view, and the first surface is a concave arc surface that adapts to the contour of the human abdomen. This curved surface design ensures that the device can fit closely to the abdomen of users of different body types, prevent lateral slippage during the application of force, and improve the stability of the application of force.
[0008] Preferably, the gripping plane of the handle has an angle with the tangential plane of the rigid main body plate. This angle is designed in accordance with ergonomic principles, making it convenient for the person applying force to use the weight of the upper body to pull downward in self-rescue mode, or to pull backward in accordance with the arm's force application habits in mutual rescue mode.
[0009] Compared with existing technologies, this invention has the following beneficial effects: 1. Effortless and efficient: This invention cleverly utilizes the lever principle, using the lower abdomen or pelvis as a fixed fulcrum, to transform the downward pressure of the user's arms or the weight of the upper body into an amplified inward and upward impact force. Even users with less strength can generate sufficient emergency pressure to dislodge airway obstructions; 2. Precise positioning: The fixed pressure protrusion, combined with the bottom fulcrum positioning, forcibly standardizes the force application position in the area above the navel, effectively avoiding displacement of the pressure position due to panic and reducing the risk of fractures; 3. Self-rescue feasibility: It completely solves the limitation of traditional self-rescue methods relying on external hard furniture. Patients only need to operate this device with their own hands to perform effective abdominal thrusts; 4. High safety: The rigid frame provides the necessary impact strength, while the flexible buffer layer and ergonomic curved surface design effectively disperse local pressure, reducing secondary physical damage to internal organs and skin during emergency treatment.
[0010] The invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] like Figures 1 to 4 As shown, this embodiment provides an abdominal emergency rescue and thrusting device, the overall design of which follows ergonomic principles. The rigid main body plate 10, in the top view (… Figure 4It is kidney-shaped or crescent-shaped, with the first surface (facing the human body) being a concave arc surface. The radius of curvature is designed to fit the contour of an adult's abdomen, ensuring a good fit and stability when force is applied. Regarding materials and structural strength, such as Figure 5 and Figure 8 As shown, this device adopts a double-layer composite structure. The internal core is a rigid skeleton layer 18, preferably injection molded from high-strength engineering plastics (such as polycarbonate PC or ABS). To reduce weight while ensuring extremely high compressive strength and preventing breakage under emergency high pressure, the rigid skeleton layer 18 is provided with several reinforcing ribs 18a (see...). Figure 8 (Cross-sectional view) The reinforcing ribs 18a are arranged in a grid or honeycomb pattern, connecting the first surface and the second surface. The outer layer of the device, especially the pressure protrusions 14 and the fulcrum abutment 16 areas in contact with the human body, is covered with a first flexible cushioning layer 20 (such as TPE soft rubber) to increase comfort and prevent soft tissue contusions.
[0013] like Figure 3 and Figure 9 As shown, the handle 12 is designed with specific ergonomic features. The grip center axis of the handle is not parallel to the tangential plane of the rigid body plate 10, but forms an outward grip angle α (e.g., ...). Figure 9 As shown, the preferred angle range is 15° to 45°. The purpose of this included angle α is to ensure that when the user pulls downwards to perform a self-rescue operation, or when the rescuer pulls from behind, the wrist can remain in a neutral position for natural force application, avoiding force transmission loss caused by excessive wrist flexion and extension.
[0014] When a user experiences airway obstruction alone (e.g.) Figure 6 (As shown), take the following steps: Grasp the handles 12 on both sides firmly with both hands and place the device horizontally in front of your abdomen; Positioning fulcrum: Press the fulcrum abutment seat 16 at the lower edge of the device downwards so that it sinks into and abuts against the firmer area of the lower abdomen or above the pubic symphysis of the pelvis (i.e., fulcrum P in the figure) to establish a stable rotation fulcrum. Force impact: The user leans forward slightly and uses the strength of both arms and the weight of the upper body to forcefully pull down the handle 12 (in the direction of arrow F1). Principle of operation: Based on the lever principle, the device rotates around the relatively fixed fulcrum abutment seat 16 as the axis, converting the downward torque into a powerful thrust on the pressure protrusion 14 in the inward and upward direction (arrow F2 direction). This thrust acts directly on the area below the diaphragm, instantly increasing intra-abdominal pressure and forcing airflow into the lungs to expel the foreign object.
[0015] When rescuing others (such as...) Figure 7(As shown): The rescuer stands behind the patient in a lunge position; the rescuer places both hands under the patient's armpits and grasps the handle 12 of the device; the rescuer aligns the pressure protrusion 14 of the device with the area between the patient's navel and xiphoid process; the rescuer pulls forcefully backward and upward in a sudden burst (in the direction of arrow F3). Because the handle 12 provides an excellent grip point, the rescuer can apply explosive force more easily than with a bare arm, and it is less likely to slip.
[0016] The above embodiments are merely illustrative, and the scope of protection of this invention is defined by the claims. Any equivalent substitutions or modifications based on the inventive concept should fall within the scope of protection of this invention.
