Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wounded person carrying, in particular to a hand-free inclined surface force-releasing carrying method. BACKGROUND

[0002] In war rescue training and actual first-aid scenes, the hand-free prone carrying method is one of the traditional wounded person carrying methods, which mainly relies on the left upper limb arm force of the rescuer to hold and the right upper limb to support the upper body weight of the wounded person to realize carrying. However, the traditional method has the following significant defects:

[0003] Limited application range: only applicable to "big" rescuers carrying "small" wounded persons, when the rescuer and the wounded person have similar height and body shape, the length of the left arm of the rescuer is insufficient, and it is difficult to effectively extend to the opposite armpit of the wounded person to form stable support.

[0004] Heavy load on the rescuer: the double upper limb arm force of the rescuer is required to be extremely high, and long-time carrying can easily lead to muscle fatigue and power depletion of the rescuer, affecting the carrying efficiency and safety, and the right upper limb of the rescuer has to bear the gravity of the upper body of the wounded person and the upper body of the rescuer itself.

[0005] Insufficient safety of the wounded person: the traditional method needs to rely on the left arm force to hold the upper body of the wounded person, and the head of the wounded person is easy to rub the ground during the carrying process due to insufficient force or center of gravity deviation, causing secondary injury.

[0006] Limited historical scene adaptability: in the period of the Liberation War and the Korean War, the soldiers had a lean body shape, small chest circumference and weight, and the defects of the traditional hand-free prone carrying method were not fully exposed; and with the change of modern human body shape, the above-mentioned defects of the method are more prominent, and it is difficult to meet the current war rescue and first-aid needs.

[0007] Therefore, a hand-free carrying technology is needed to break through the limitations of the traditional method, reduce the physical consumption of the rescuer, expand the application range, and improve the safety of the wounded person carrying. SUMMARY

[0008] The purpose of the present application is to overcome the defects of the existing hand-free prone carrying method, provide a hand-free inclined surface force-releasing carrying method, and achieve the following objectives:

[0009] Expand the application range, so that rescuers of different heights and body shapes can stably carry wounded persons whose height is higher than or similar to their own;

[0010] Significantly reduce the load on the double upper limbs of the rescuer, reduce muscle fatigue, and improve carrying sustainability;

[0011] Avoid secondary injury such as the head of the wounded person rubbing the ground, and improve the safety of the wounded person during the carrying process;

[0012] Optimize the forward force mode to ensure the efficiency and controllability of the forward movement during the carrying process.

[0013] The hand-free inclined plane unloading carrying method is characterized in that it comprises the following steps:

[0014] (1) Reconstruct the support system: adopt the support mode of "right thigh, waist muscle, back muscle, and right upper limb", the lateral surface of the right thigh, the right side of the trunk, and the upper arm side of the right upper limb are in contact with the ground, the contact surface is in the shape of a long strip, the upper body of the injured person is placed on the upper body of the rescuer, the gravity of the upper body of the two is supported by the abdominal muscle, the waist muscle, the pectoral muscle, and the back muscle, i.e. the core muscle group, and is finally transmitted to the ground through the "long strip" contact surface. In this way, the bearing force of the rescuer is dispersed from the original three points to the long strip surface, and the difficulty of the rescuer is greatly reduced. The body of the injured person is in an inclined plane state, the thighs and hips of the injured person are in contact with the ground, the waist and upper body are supported by the waist and back muscles of the rescuer and the right upper arm, and the left upper limb is stretched to the left chest position of the injured person to grasp the clothes to achieve auxiliary fixation;

[0015] (2) Adjust the inclination: according to the height of the injured person and the arm strength of the rescuer, move the support position of the right thigh of the rescuer, and can transfer the bearing force of the upper body of the injured person to the waist and back of the rescuer by expanding the inclination, the inclination of the injured person and the inclination of the rescuer overlap each other, and the bearing force of the upper limbs of the rescuer can be transferred and reduced;

[0016] (3) Cooperative force forward: take the lower limbs of the rescuer as the main force component, the right upper limb as the secondary force component, and cooperate with the fixing action of the left upper limb to realize the overall forward movement;

[0017] (4) Observation and adjustment: through the combination of observation before carrying and observation during the stop, the safety of the forward route is ensured.

[0018] Preferably, the "unloading" is achieved by adjusting the support position of the right thigh of the rescuer, so that the weight of the injured person is transferred to the ground, and the injured person of different heights is adapted.

[0019] Preferably, the inclined plane state of the injured person is achieved by adjusting the angle between the plane of the rescuer's trunk and the ground, reducing the stress load of the left arm, and adapting to injured persons of different weights and sizes.

[0020] Preferably, the left upper limb does not need to be around the opposite armpit of the injured person, but only needs to grasp the clothes on the left chest to achieve fixation, and the stress load is significantly reduced.

[0021] Preferably, the gravity of the waist and lower body is transferred to the ground through the hips of the injured person, the friction generated by the contact of the thighs and hips of the injured person with the ground is used to share the gravity of this part, and the bearing pressure of the rescuer is reduced.

[0022] Preferably, it is suitable for scenes such as war rescue and daily first aid, and a 1.6-meter-high rescuer can carry an injured person who is 1.75 to 1.8 meters high.

[0023] The beneficial effects of the present application are:

[0024] Wide range of applications: Breakthrough the traditional method of rescuer and the height, weight, body shape of the wounded, for example, 1.6 meters high rescuer can stable transport 1.75 meters to 1.8 meters high wounded, in the dangerous area of the battle low posture transport;

[0025] Low load of rescuer: The right upper limb and the left upper limb are greatly reduced, and there is no need to bear the main load task, the synergistic force of the lower limbs and the waist and back muscles is more in line with human mechanics, and the muscle fatigue and physical expenditure are reduced;

[0026] High safety of the wounded: The wounded is in a inclined plane state, which avoids the risk of head rubbing the ground caused by excessive concentration of the upper body weight, and the ground support of the waist and lower limbs further improves the body stability, reduces the probability of secondary injury, and the left upper limb of the rescuer needs greater arm force to hold the upper body of the wounded in the traditional method, so that the wounded can not rub the ground.

[0027] Flexible and convenient operation: without additional tools, only by adjusting the support fulcrum and the degree of inclination can adapt to different situations, the forward force mode is simple and efficient, and it is convenient to quickly master and practical application.

[0028] Obviously, according to the above content of the present application, according to the ordinary technical knowledge and conventional means in the art, other various forms of modification, replacement or change can be made without departing from the above technical idea of the present application.

[0029] The above content of the present application will be further described in detail by the specific embodiments. However, it should not be understood that the scope of the above subject matter of the present application is limited to the following examples. Any technology realized based on the above content of the present application belongs to the scope of the present application. DETAILED DESCRIPTION

[0030] The present application will be described in detail below with specific examples, which is not a limitation of the present application.

[0031] The bare-handed inclined plane unloading carrying method of the present application is to change the vertical force state of the wounded in the traditional carrying to the inclined force state, and to realize efficient and safe carrying through force point reconstruction and force mode optimization. The specific steps are as follows:

[0032] (1) Force structure reconstruction,

[0033] Change the three-point support mode of "right thigh, right upper limb, left upper limb" in the traditional carrying to the new support system of "right thigh, waist muscle, back muscle, right upper limb", wherein:

[0034] The lower half of the waist of the injured person is not in contact with the ground, and is in an empty state, and only the lower limbs and hips of the injured person are in contact with the ground between the hips of the injured person and the thighs of the rescuer;

[0035] The upper body gravity of the injured person is supported by the waist and back muscles of the rescuer and the right upper limb, and the left upper limb only needs to extend to the left chest position of the injured person to grab the clothes, without needing to go to the opposite armpit, greatly reducing the load of the left upper limb.

[0036] (2) the angle of the inclined plane is adjusted,

[0037] According to the weight and size of the injured person and the arm strength of the rescuer, the inclination of the body of the injured person is flexibly adjusted:

[0038] The outer side of the right thigh of the rescuer, the right side of the waist and chest, and the outer side of the right upper arm are in contact with the ground, supporting the upper body weight of the injured person, so that the inclined plane of the injured person and the inclined plane of the rescuer overlap each other, which can transfer and reduce the load of the upper limbs of the rescuer;

[0039] When encountering an injured person with a large body weight and wide shoulders, the angle of the inclined plane needs to be adjusted to be larger, and vice versa. When the angle of the inclined plane is small, the injured person will slide down, which increases the burden of the left arm. Therefore, the size of the inclined plane is determined by the arm strength of the rescuer and the weight and size of the injured person.

[0040] Unlike the prone carrying method (the right side of the waist and chest of the rescuer is not in contact with the ground, and the outer side of the thigh of the rescuer and the right upper arm are empty between the upper limbs, and the weight of the upper body of the injured person is supported by the right upper limb), which greatly reduces the load of the right upper limb;

[0041] Because the area of the rescuer supporting the weight of the injured person is increased to a long strip shape, the load of the rescuer is dispersed, the right upper limb of the rescuer is changed from the original direct support to a non-support, and the right side of the thigh and the right side of the waist and chest become supports, so the flexibility of the forward movement of the right upper limb is greatly enhanced.

[0042] (3) the forward force generation mode,

[0043] During the forward movement, the lower limbs of the rescuer are the main force generation components, and the right upper limb is the secondary force generation component, and the two cooperate to push the whole forward, replacing the mode of relying on the upper limbs in the traditional method, and improving the forward efficiency and physical endurance.

[0044] (4) observation and route selection,

[0045] The combination of "observation before carrying + observation during stop" is adopted to make up for the inconvenience of direct observation caused by the inclined state of the injured person, to ensure that the rescuer can accurately judge the forward route, and to ensure the safety of carrying.

[0046] The following will combine specific application scenarios to explain the implementation steps of the present application in detail:

[0047] Preparation stage,

[0048] Rescuers first observe the injured person's condition and the surrounding environment to determine the route forward; they then adjust their own position according to the injured person's height to ensure the injured person is in a position that is easy to support.

[0049] Support construction,

[0050] The rescuer places their right thigh on the injured person's waist or the lumbar-chest junction (depending on the injured person's height), creating an oblique plane around the injured person's body. The rescuer tightens their back muscles, supports themselves with their right upper arm on the ground or the side of the injured person's body, and extends their left upper arm to the injured person's left chest, grasping clothing for additional fixation. Simultaneously, the chest and abdominal muscles engage in the effort. At this point, the injured person's thighs, buttocks, and lower back are in contact with the ground, while the upper body is supported by the rescuer's back muscles and right upper arm, completing a coordinated "ground-rescuer" support system.

[0051] Incline adjustment,

[0052] The injured person's lower body is actually suspended between the rescuer's right thigh (which is in contact with the ground) and the injured person's buttock (which is in contact with the ground). When the rescuer feels that the left upper limb is still under pressure, the slope of the injured person's body can be appropriately increased. By adjusting the support position of the right thigh (slightly adjusting upwards), the weight of the injured person's upper body is further transferred to the rescuer's waist and back, and towards the ground, until the left upper limb only needs to bear a slight fixing force.

[0053] Forward implementation,

[0054] The weight of the injured person's upper body is borne by the rescuer's back muscles. Because the right side of the rescuer's back is in a long strip along the back of the armpit and is in contact with the ground for support, the right upper limb bears more than 90% of the weight, and the left upper limb also bears more than 60% of the weight. When moving forward, the right upper limb only needs to easily cooperate with the pushing force of both lower limbs. The left upper limb keeps the injured person in place to prevent their body from swaying. Every so often, a short pause can be taken to observe the route and the injured person's condition to ensure safe transport.

[0055] Final stage,

[0056] After moving the injured person to the target location, slowly adjust the injured person's position, remove the support, and ensure that the injured person lands smoothly or is transferred to other rescue equipment.
