Description

Wounded person hauling belt

Technical Field

The application belongs to the field of medical first-aid equipment, and particularly relates to a wounded person hauling belt.

Background

Under the conditions of fire line, fire, explosion and toxic site, the injured soldier or wounded person should be transferred to a safe place as soon as possible and then rescued. In the transferring process of the injured person, due to the influence of the injured part and the injured condition, such as injured limbs or unconscious injured persons, the assisting rescue cannot be responded, the rescue personnel need to finish the transferring of the injured person independently and suppress the fire of enemies or perform other tactical actions, and therefore the injured person cannot be transferred in the conventional modes of holding, carrying and the like.

The field operation wounded personnel carry mainly relies on the stretcher, but the stretcher weight is about 10kg, even the present lighter carbon fiber stretcher, also because the volume is not dwindled, folding back size is not less than 200 cubic decimeters, after the emergency personnel carries the stretcher, can not carry first aid equipment again, often only can implement the transport operation. As a short-distance wounded person departs from the range of direct aiming fire of individual soldiers in enemies, the first aid strength of the class ranks such as sanitary soldiers and sanitary workers is inconvenient to carry, and manpower and material resources are wasted when the first aid strength is specially carried.

Utility model CN 207071119U discloses a safe laborsaving type wounded handling tool in battlefield, accomplished to subtract and subtract heavy and reduce the volume with the stretcher really, the fact is wounded sits on the layer board that has the gyro wheel, move, the gyro wheel can reduce the drag strength really, but open-air landform is rugged and uneven, the cross-country ability of trundle hardly has, if the condition that the hole hollow just can not go or take place the wheel and trap in, 3 rows of wheels of 50 kilograms plus the layer board need be undertaken at least, the quality must exceed 1 kilogram, if calculate other parts, the quality must exceed 2kg, the layer board plane also will exceed 6 square decimeters, these problems all cause the individual soldier can't carry. Utility model patent CN207654358U, the name is "be used for wounded's quick draw gear" and utility model patent CN205814549U, the design usage who is named "wounded's handling area in armoured" is to mention perpendicularly and shifts out outside the storehouse with the wounded in the tank bin, and these two kinds of devices all need the wounded to just dress before not getting unworn, if dress after the injury, if the problem lies in if have the ability to wear this kind of handling equipment, have ability oneself to climb out outside the storehouse, if oneself does not have the ability to dress, and crotch portion is fixed just needs others to assist, unfortunately, in narrow and small tank bin, there is the people to replace the fixed crotch portion of wounded, do not like directly ask the wounded to mention the cabin. Utility model patent CN 205094813U, the name "a towing gear for live wire treatment wounded" adopt three layer boards, and middle backing plate both sides are the arc to the kickup, and both sides still need be linked through hinge and curb plate, otherwise three boards can't make up the use. The purpose of the splint is to reduce the injury caused by the head of the wounded swinging left and right. Because the backing plate is the arc, middle backing plate and the unable laminating of both sides backing plate occupy great space when not using, will can be fixed the head moreover, the curb plate will be fixed with the wounded armpit, so whole length can not be less than 40cm, receives the space restriction equally, and the individual soldier carries the difficulty. The rope belt in the diagram is also short, so that the back of the wounded is convenient to lift, but the angle for hauling the wounded is labored. The hinge and the joint of the rope belt and the backing plate are also easy to deform and damage in the dragging process. Utility model patent CN205055250U, name are "wounded's braces" each department is fixed all need peg graft through the eye-splice, troublesome poeration, and the intensity of eye-splice is limited moreover, and the eye-splice is more, when bearing great strength, and the probability of failure is also higher. The fixing belts at different parts, which are vertically designed, are combined in a sewing mode instead of a belt body, the sewing strength is far lower than that of an integrated woven belt, and the probability of fracture and failure is also high. The structural design of this patent mainly used bears the wounded, and the battlefield can not adopt the mode of bearing the wounded under local individual soldier's firepower suppression. And therefore, cannot be used for hauling the wounded.

When the wounded are transported, the transporting rescue personnel can use the wounded hauling belt to haul the wounded to leave the dangerous area as soon as possible. As a short-distance hauling device carried by an individual soldier, the weight is not more than 500g, and the volume is not more than 1 cubic decimeter.

In view of this, the present application is specifically made.

As used herein, the singular forms also include the plural forms unless the context clearly dictates otherwise, and further, it is understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of the stated features, steps, operations, devices, components, and/or combinations thereof.

The technical solutions of the present application will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The wounded hauling belt is a short-distance hauling equipment used for being carried by an individual soldier, and is not suitable for being more than 500g in weight and not more than 1 cubic decimeter in volume in order to carry the carrying requirement. The embodiment of the application provides a wounded person hauling belt, which comprises a wounded person fixing part and a manual hauling part; the manual dragging part is connected with the wounded fixed part in sequence. The wounded fixing part is used for fixing the wounded on the wounded hauling belt, and the manual hauling part is used for the rescue worker to haul the wounded. The structure schematic diagram of the embodiment of the application is shown in fig. 1. As can be seen from FIG. 1, the traction belt for the wounded comprises a woven belt which is folded in half to form a Y shape, and the Y-shaped forked part is a manual traction part 11; the vertical bottom of the Y shape is a wounded fixed part 12. The wounded haulage belt is an integrated splicing-free design, and the overall strength of the wounded haulage belt is guaranteed. The wounded's fixed part is provided with fixing device, and the head of manpower dilatory portion is provided with lifting device. The junction of the manual traction part and the wounded fixing part is provided with an overlapping fixing point (stitching point) 126, and the overlapping fixing point 126 is used for fixedly connecting the two folded braids. The victim fixing portion 12 includes a webbing sewn from the folded-over point to the overlapped fixing point 126; the human power traction portion 11 is formed by overlapping the webbing between the fixing point 126 and the two free ends of the webbing to form a Y-shaped wounded person haulage belt structure.

In the embodiment of the present application, the lifting device 111 includes two lifting loops, which are respectively disposed on two parts of the Y-shaped fork; the lifting ring sleeve is an annular structure with the circumference of 400-600 mm formed by folding back and fixing two free ends of the braid, namely two ring sleeve structures are formed.

In the embodiment of the application, the wounded fixing part adopts a hook-lock structure; the hook and lock type structure comprises a hook 125 and a fixed braid; when the hook lock type wounded person hauling belt is used, the hook can be directly hooked on a hanging point on the back of the body or the clothes of the wounded person during the operation with a single soldier, or the woven belts of the hook and the wounded person fixing part are hung back to the fixed woven belts after being wound around the ankles or the armpits of the wounded person for a week, so that the wounded person fixing part forms a lantern ring to fix the wounded person.

The effective length of the dragging part of the wounded hauled belt is designed as follows:

the towing belt length, hand functional height, coefficient of friction affect the horizontal towing wounded force, as shown schematically in fig. 2. Because the rescue personnel and the wounded persons move close to the same speed on the ground with the same friction coefficient, the smaller the included angle between the towing belt and the horizontal ground is, the lower the physical energy consumption of the rescue personnel for towing the wounded persons is, although the towing belt is not provided with a labor-saving mechanism.

When the rescue personnel moves at a uniform speed, the horizontal component force of the rescue personnel and the static friction force of the wounded can be equal to pull the wounded, the force application of the rescue personnel is set as F, the included angle between the force application direction and the ground is theta, the weight of the wounded is m, as shown in figure 2, the friction coefficient between the wounded and the ground is mu, and the following steps are provided:

Fcosθ＝μ(mg-Fsinθ)

F＝μmg/(cosθ+μsinθ)

when the wounded is hauled, the ground friction coefficient can have obvious influence on the force application effect. However, because there is no friction data between the human body and the ground, considering that rubber and human muscle have certain similarity, chemical fiber clothes are arranged between the muscle and the road surface after the wounded person lies down, and the sole of the rescue worker is usually made of rubber, the film material coefficient of the road surface and rubber is adopted as reference during calculation, according to the JTG D50-2004 road asphalt pavement design specification, and the literature such as the experimental research on the influence of different road surface conditions on the road surface friction coefficient, the dry asphalt road surface friction coefficient is more than 0.6, the sand road surface can be reduced by 30 percent and about 0.42, the road surfaces such as an icy road surface, a wet slippery road surface and a grassland can be reduced to below 0.3, and the calculation relationship between the force application condition and the angle is shown in Table 1.

TABLE 1 values of μ/(cos θ + μ sin θ) under different force application angles and friction coefficients

The calculation shows that the labor-saving angle theta is 0.6 of the friction coefficient₁Is 30-32 degrees, the friction coefficient of the sand ground is 0.42, and the labor-saving angle theta₁About 21 to 23 degrees, the friction coefficient of the ground such as ice road, wet and slippery road or grassland is usually 0.3, and the labor-saving angle theta₁Is 16-18 degrees.

And theta₁The opposite right-angle side has high hand function, and the length of the dragging part of the hauling belt can be calculated according to the high hand function of the Chinese human body in GB10000 Chinese human body size.

Taking the average value of the hand function height of 18-55-year-old female of 630mm, no bending of a rescuer and a 32-degree angle as an example, the effective length of a manual traction part dragged by a wounded person at least needs to meet 1188 mm. Taking the male (18-25 years old) 99 quantile hand function height 831mm, the rescuer does not bend over, and the angle of 32 degrees as an example, the effective length of the manpower dragging part of the wounded hauling belt at least needs to meet 1568 mm. Therefore, the human force traction part is arranged at a position which is at least 1188mm, preferably at least 1568mm from one end of the Y-shaped branch to the wounded haulage belt along the length direction of the wounded haulage belt, and the effective length of the human force traction part in the application includes the condition of elastic elongation considering that the haulage belt has a certain amount of elastic elongation when dragging the wounded.

The length of the wounded fixing part is designed as follows:

the length of the wounded fixed part is based on the principle of effectively fixing the wounded, and the wounded is not required to be considered in size if the wounded combat uniform is provided with a direct anchoring hanging point. When no direct anchoring hanging point exists, the hauling belt needs to be fixed through the armpit, ankle and other parts of the wounded by the binding sleeve, the chest circumference of the wounded and the closed circumference of the feet of the wounded are related, the closed circumference of the feet of the wounded has no data in national standard, the closed circumference of the feet of 20 men is measured, and the average size is 400 +/-50 mm. The size and chest circumference range of the human body in China is 710-1036 mm, so that the fixing part containing the hook can reach 1036 mm. Considering that the minimum chest circumference is 710mm, the size of the shortest manual traction part is 1188mm, and the length between the outer end point of the hook and the outer end point of the lifting ring sleeve of the manual traction part is not less than 2000 mm. Because wounded's haulage area is Y style of calligraphy structure, more is fit for a wounded of two people haulage, and two personal haulage force is showing and is greater than one alone, can also be fixed in the trailable clothes that the wounded wore through the couple simultaneously, can reduce haulage area weight and volume on the one hand, even need fix the wounded armpit, this size also can cover most wounded.

In this embodiment, the overlapping anchor points 126 are located 300-1000 mm from the anchor, where the doubled-over overlapping webbing is sewn together.

The design method of the intensity of the hauling belt of the wounded comprises the following steps:

in order to ensure the safe transfer of the wounded, the wounded hauling belt needs to adopt a high-strength, wear-resistant, flame-retardant and light material to adapt to a complex and severe rescue environment. The traction belt of the wounded drags the wounded from rest to the moment of starting to move to bear the maximum tensile force. Although the direction of the towing belt pull is at an angle to the victim, it is not possible to exceed 90. The pull start speed may not exceed the tensile impact of the free fall on the belt. Therefore, the requirement on the strength of the belt body is not high. The walking speed of a person under no load is about 1.38 m/s. In the case of dragging load, the initial speed of the wounded should not exceed 1m/s and the ultimate amplification should not exceed 2m/s due to the problems of the weight and friction of the wounded. The time for the wounded to instantaneously generate the motion speed will not be very fast by the manual hauling, and is estimated according to 0.1s and 0.05 s.

According to the momentum impulse relation:

TABLE 2 estimation of towing starting force of wounded with different qualities

According to table 2, wounded's haulage area fracture brute force is greater than 4kN and just can satisfies wounded's dilatory requirement, in order to guarantee breaking strength, and the preferred wounded haulage area of this application embodiment is a whole root area body, and wounded's fixed part and the design of the drawn portion integration of manpower do not splice, and the ring cover passes through the folding formation of meshbelt, and the meshbelt does not splice.

The breaking strength of the hauling belt of the wounded is more than 4kN, the tearing, the breaking and the line opening of the woven belt can not occur under the condition of 4kN, and the requirement of the wounded on slow short-distance dragging can be met. The length of the sewing part of the folded mesh belt is not less than 40mm, and the strength is not less than 4 kN.

Under the requirement of the strength calculation, the wounded hauling belt is made of aramid fiber or flame-retardant nylon (chinlon) and flame-retardant polyester material which are plain woven, twill woven, herringbone woven or pit woven belts. The preferable structure of the mesh belt is a hollow double-layer structure, so that the crowding of the edge of the mesh belt to muscles of a wounded person can be effectively reduced, and the schematic cross-sectional structure diagram of the hauling mesh belt is shown in fig. 3. The width of the woven tape is not less than 20mm, and preferably 20-30 mm.

Towing belt strength also relates to the hitch. The towing belt only pulls a static wounded person, and considering that the maximum impact force which can be born by a human body is 12KN, and the towing belt is not used for high-altitude falling protection, the hook-and-loop strength is required to be not lower than 7 kN.

As mentioned above, wounded's haulage area convenient to use of this application embodiment can be with wounded's quick, convenient being fixed in on the haulage area, and do not need excessive transport, individual soldier can accomplish fixedly, can effectively be applied to the rescue under environment such as narrow and small space, naval vessels and vehicle cabin. Simultaneously, the wounded's fixed band of this application embodiment has weight is little, small, carries convenient technical advantage.

Although the present application has been described with reference to preferred embodiments, it is not intended to limit the scope of the claims, and many possible variations and modifications may be made by one skilled in the art without departing from the spirit of the application.
