[0003] Mechanical tourniquet with two-stage operating mechanism and individual first aid kit comprising such tourniquet

[0004] Technical field

[0005] The present invention relates to a new mechanical tourniquet with two-stage operating mechanism, the tourniquet being applied to an injured limb in order to constrict the flow of venous as well as arterial blood, to an individual first aid kit comprising such tourniquet and to a method of use thereof. The invention therefore relates to a medical device falling within the scope of health care and life-saving equipment.

[0006] Background art

[0007] Tourniquet application belongs to basic methods of stanching extensive, primarily arterial blood flow, when a massive blood loss is imminent and application of a pressure bandage is unsuitable or physically problematic, i.e. in situations when the wound cannot be pressed manually. Even though the duration of tourniquet application is limited due to possible damage caused to a limb by restricted blood supply, a time period not exceeding one hour is generally considered relatively harmless and represents the easiest and fastest method how to stanch massive bleeding. Although applying a tourniquet to a wound is in fact a rather brutal technique, it plays an irreplaceable role in basic medical treatment, e.g. under combat conditions, prior to transport of an injured person to a surgical ward, or in case the first aid provider is not a trained paramedic.

[0008] Various types of tourniquets are known in the art that have been used for constricting the blood flow to a limb. For many years, tourniquets have constituted basic equipment of stationary as well as mobile first aid kits. A fundamental component of a tourniquet is a strap, also called a tightening strap, made of rubber or fabric. The tightening strap is long enough to be easily wrapped around a human limb. Both ends of the strap are connected by a knot or various connecting pieces forming a tightening lock. Nevertheless, it is always necessary to encircle the injured limb thoroughly and to apply tensile force sufficient to constrict completely the blood circulation in the affected limb.PV 2025-59

[0009] 2

[0010] A rubber tourniquet constricts a limb due to its flexibility. In fabric tourniquets, constriction of the affected limb is accomplished by tightening essentially inflexible strap by force so that circumference around the limb is minimised and the limb therefore constricted. This operation being physically rather demanding, it is also vital to secure the constriction to avoid necessity of constant application of strong compressive force even during transport of the injured person.

[0011] Tourniquets used in military combat care comprise resilient tightening strap made of fabric, wherein an anchoring buckle is situated at the first end of the strap while a tightening buckle is situated at the second end of the strap. Such an arrangement enables to thread the strap through multiple loops, with the loose end of the strap protruding from the tightening buckle. Both buckles are either parts of one compact whole and the tourniquet is therefore slided onto the limb essentially in an assembled state, or they comprise connecting elements, which enable direct application of a disassembled tourniquet and subsequent assembly of its ends on the spot only. The anchoring buckle and the tightening buckle form a tightening lock. Upon application of the tourniquet and its assembly into one whole, the loose end of the strap is pulled by tensile force and the tourniquet becomes tightened. The presence of the tightening buckle is advantageous, since its construction enables automatic securing of the strap in the tightened position of the tourniquet. To make the tightening firmer and to achieve full function of the tourniquet even when applied over the injured person’s clothes, the tourniquet is additionally equipped with a secondary tightening element comprising a sewn-on shorter strap with a metal bar. The secondary constriction is achieved by rotating the metal bar which leads to twisting of the secondary strap, the ends of which connect two points of the primary strap, thus bringing them closer and making the tourniquet even tighter. The limb constriction employing such bar is physically less demanding. Additionally, the tourniquet is equipped with a hook-and-loop fastener or a pocket, which enable immobilisation of the metal bar in one position after the constriction, thus preventing loosening of the constriction and unintended unwinding of the strap.

[0012] The main drawback of the tourniquet device mentioned above stems from the fact that for constriction, i.e. for primary and secondary constriction stages, respectively, two fully functional hands must be employed. Besides, the process itself is rather extended. This factor is especially important in case it is the victim themself who must perform the constriction, i.e firstly to find the tourniquet in their gear, and subsequently to unpack and apply it, and finallyPV 2025-59

[0013] 3

[0014] to constrict their own limb. Moreover, only one tourniquet is usually comprised in a soldier’s mandatory military gear. In case more limbs of one person have been injured, it is necessary to employ their colleagues’ tourniquets as well.

[0015] The main goal of the present invention is to eliminate drawbacks of prior art and to provide a novel tourniquet, the use of which would be easier and less time-consuming. The tourniquet of the present invention should be primarily self-applicable by the victim. Another goal of the present invention is to provide a tourniquet as a component of individual first aid kit, enabling to constrict even all four limbs of one injured person, i.e. without the necessity to employ another soldier’s toumiquet / s.

[0016] Description of the invention

[0017] Drawbacks of currently known mechanical, i.e. non-pneumatic, tourniquets with two-stage operating mechanism are overcome by the mechanical tourniquet with two-stage operating mechanism of the present invention described hereinafter, which is for easier and faster application incorporated into the military gear in form of an individual first aid kit. Due to its novel design, the mechanical tourniquet of the present invention is adapted for a very quick application by the injured person, or the first line responder. The victim themself is able to apply the tourniquet using only one hand, i.e. in case their second limb is injured and blood flow has to be constricted. Such tourniquet application is fairly easy. Incorporation of mechanical tourniquets into the combat gear / military equipment guarantees that the injured person always has enough of their own tourniquets within an easy reach, so that effective and fast first aid can be provided without the necessity to employ other persons’ military equipment. Therefore, situations are prevented in which the injured soldier’s fellow combatants need their equipment for their own use. Besides, incorporation of tourniquets into the military gear completely eliminates the need for transport of a suitable tourniquet to the destination, because it is already available on the spot in the moment of the traumatic injury.

[0018] In the basic embodiment, the mechanical tourniquet according to the invention comprises the tightening strap equipped with one-piece compact tightening lock. The first constriction stage consists in tightening the loose end of the tightening strap, i.e. tightening by application of manual force around a single windlass, represented by the top securing crossbar. The secondPV 2025-59

[0019] 4

[0020] constriction stage consists in tightening the tightening strap using a short lever, i.e. the end of the tightening strap anchored to the lever pivot and threaded around tightening crossbars.

[0021] The mechanical tourniquet with two-stage constriction mechanism is primarily intended for fast stanching of bleeding limbs by the victim themself. Mechanical tourniquet comprises the tightening strap fastened in the tightening lock with one end loose and the other end anchored. Individual components of the tightening lock make up one compact non-disassemblable whole. The tightening lock is comprised of the body having a pair of lateral sides in its bottom part, the lateral sides coupled by the body base into one compact whole. In the rear part of the body, the base forms a brake projection. In the front top part, the lateral sides are further connected by a top securing crossbar, while in the rear lower part also by a reinforcing crossbar. The tightening lock further consists of a brake in the rear part of the body, the brake rotating on a brake pivot. The brake pivot is firmly anchored in brake apertures, the apertures being parts of the lateral sides. The brake is situated in the space between the reinforcing crossbar and the brake projection. The brake is equipped with a compression spring which applies force of the brake on the tightening strap and keeps it pressed on the brake projection. This arrangement prevents spontaneous unitended unwinding of the tightening strap from the tightening lock. The tightening lock further comprises a lever for secondary tightening of the tightening strap. The top surface of the lever is in at least a part of its length equipped with lateral surfaces having the tightening crossbar between them. The lever is anchored on the lever pivot, which is firmly anchored in lever apertures of the lateral sides and also in lever apertures situated opposite each other on both lateral surfaces of the lever. The tightening lock further comprises a securing rivet which is arranged slidingly in securing apertures. The securing apertures are situated opposite each other in the front part of lateral sides and press the tightening strap to the top securing crossbar by means of the securing rivet. One end of the tightening strap is firmly anchored to the lever pivot from where it continues over the tensioning crossbar, between the brake projection and the brake itself and then out of the tightening lock. The tightening strap is subsequently threaded between the top securing crossbar and the securing rivet, the loose end of the tightening strap leaving the tightening lock in its front top part.

[0022] In one preferred embodiment, the brake is in its part, which presses the tightening strap, equipped with teeth. The teeth increase the downward pressure effect and intensify resistance to unintended loosening of the tightening strap from the tightened position.PV 2025-59

[0023] 5

[0024] In another preferred embodiment, the brake is in its bottom central part equipped with an inner groove, in which there is a compression spring on the brake pivot, the compression spring being of coiled torsion type. One arm of the compression spring is supported against the inner groove of the brake, while the other arm is supported against a mortise reinforcing crossbar.

[0025] In another preferred embodiment, the lever is in its front part opposite its anchoring on the lever pivot from the bottom side of the top surface equipped with a cogged part. The cogged part serves for easier grip of the lever top surface, i.e. it prevents slipping of fingers when grasping the lever.

[0026] In another prefereed embodiment, the lever is in its front part opposite its anchoring on the lever pivot equipped with an aperture, in which there is a grip strap for easier, i.e. faster grasp of the lever.

[0027] The layout of the individual first aid kit of the present invention guarantees its individual use directly by the injured person, who is able to provide the first aid even when it is necessary to constrict more than one of their limbs, provided that at least one of their upper limbs is functionally intact. For this purpose, the individual first aid kit of the present invention consists of at least four mechanical tourniquets, which are laid out in such a way that they make up a compact component of the garment, i.e. of the military gear. On the garment, at least one mechanical tourniquet is always present at such a position on the limb which is closest to the trunk, so that the limb is constricted as close to the trunk as possible. Tourniquets may be attached to the garment in several different ways. For example, the garment is on its perimeter equipped with loops, through which the mechanical tourniquet is passed. At the same time, the tightening lock body is through its anchoring surfaces and anchoring apertures therein attached to the fabric by seams or by rivets. Anchoring may be also accomplished by application of other joining techniques commonly used in textile manufacturing.

[0028] In one preferred embodiment of the present invention, each external side of the body behind the lateral sides is equipped with an anchoring surface. The anchoring surface is equipped with at least one anchoring aperture, which enables firm anchoring of the tightening lock to the garment.PV 2025-59

[0029] 6

[0030] In another preferred embodiment of the present invention, the loose end of the tightening strap is covered with a fabric covering of the same colour as the gear and equipped with a hook-and-loop fastener. One component of the hook-and-loop fastener is situated on the mechanical tourniquet and the second component of the hook-and-loop fastener is situated on the gear. Nevertheless, the gear as such is not comprised in the individual first aid kit.

[0031] The mechanical tourniquet is integrated into individual first aid kit. In the first stage, the injured person or the first aid provider grasps the loose end of the tightening strap - with or without a fabric covering - and separates it from the gear, i.e. pulls the hook and loop fastener apart. In the second stage, the loose end of the tightening strap is pulled by applying force in the opposite direction, i.e. back along top securing crossbars, thus tightening the tightening strap. Tightening is to be understood as circumference reduction of the tightening strap. The top securing crossbar and the securing rivet secure blocking of the tightened position of the tightening strap in the tightening lock, preventing unintended, spontaneous loosening of the tightened strap. Thus, the first stage of the mechanical tourniquet tightening is accomplished.

[0032] In the second stage, the lever is grasped either directly, or using the grip strap, whereupon the lever is rotated around the lever pivot in the direction away from the limb. The end of the tightening strap, which is firmly anchored to the lever pivot, is accordingly by the force over the lever, which is in the form of the tightening crossbar, pulled up and secured in this position by securing the tightening strap between the brake and the brake projection. The operation described above represents essentially the second stage of the mechanical tourniquet tightening. Thus, the second stage of the mechanical tourniquet tightening is accomplished.

[0033] The main advantage of the present solution lies in the fact that the use of mechanical tourniquet of the invention is easier and less time-consuming, i.e. faster. The tourniquet may be selfapplied even by the injured person themselves who has unlimited mobility of at least one upper limb. Using the kit, the victim is able to constrict all four own limbs and forestall exsanguination before another person arrives at the scene to provide appropriate help, which is a quality the currently available mechanical tourniquets lack.

[0058] Examples

[0059] Example 1

[0060] In one specific embodiment of the present invention, which is depicted on Figures 1 to 21, the mechanical tourniquet with two-stage operating mechanism consists of two basic components, namely a tightening strap 1 and a tightening lock 2. The length of the tightening strap 1 is adjusted according to the size of the garment the mechanical tourniquet is attached to. ThePV 2025-59

[0061] 8

[0062] tightening strap 1 is made of polypropylen, its width amounts to 20 mm, its thickness amounts to 0,7 mm and the value of tensile force is 1.800 N.

[0063] The tightening lock 2 consists of one compact non-disassemblable whole. The mechanical tourniquet is therefore applied in the assembled state by sliding it onto the injured limb. The tightening lock 2 consists of a body 3 with a pair of lateral sides 4, which are interconnected by the base 5 in the bottom part of the body 3. The base 5 in the rear part of the body 3 projects into a brake projection 6. In the front top part the lateral sides 4 are further interconnected by the top securing crossbar 7 and in the rear bottom part also by the reinforcing crossbar 8. The body is optimally made as one compact unit, e.g. a cast, from a light solid material, e.g. aluminium. In front part opposite its anchoring on the lever pivot 16, the bar 12 is from the bottom part of the top surface 13 for at least a portion of the front edge of the top surface 13 equipped with a cogged part 22 for easier grip of the bar 12. On its external sides behind the lateral sides 4, the body 3 is equipped with anchoring surface 23 having one anchoring aperture 24 for anchoring of the tightening lock 2 to the garment.

[0064] In this specific embodiment, the tightening lock 2 further comprises the brake 9, which is arranged in a rotary fashion on the break pivot 10 in the rear part of the body 3. The brake pivot 10 is anchored in brake apertures 21 of the lateral sides 4, the apertures 21 being opposite each other. The brake 9 is situated in the space between the reinforcing crossbar 8 and the brake projection 6. The brake 9 is equipped with a compression spring which applies force of the brake on the tightening strap 1 and keeps it pressed on the brake projection 6. This arrangement prevents spontaneous, unitended unwinding of the tightening strap 1 from the tightening lock 2.

[0065] The tightening lock 2 further comprises a bar 12 for secondary tightening of the tightening strap 1. The top surface 13 of the bar 12 is in at least a portion of its lenght equipped with lateral surfaces 14 with the tightening crossbar 15 situated between them. The bar 12 is anchored in a rotary fashion on the lever pivot 16, which is firmly anchored in lever apertures 17 of the lateral sides 4 of the body 3 and lever apertures 17 situated opposite each other on both lateral surfaces 14 of the bar 12. The tightening lock 2 further comprises a securing rivet 18, which is arranged slidably in securing apertures 19 being opposite each other in the front part of lateral sides 4 ofPV 2025-59

[0066] 9

[0067] the body 3. The securing rivet 18 together with the securing crossbar 7 make up pressure surface for pressing of the tightening strap 1 in the adjusted position in the first constriction stage.

[0068] The tightening strap 1 is arranged so that one end of the tightening strap 1 is firmly anchored to the free part of the lever pivot 16, and is further threaded over the tightening crossbar 15, between the brake projection 6 and the brake 9 and out from the tightening lock 2. The tightening strap 1 is then threaded back between the top securing crossbar 7 and the securing rivet 18. The loose end of the tightening strap 1 finally leaves the tightening lock 2 in its front top portion.

[0069] In this embodiment, the brake 9 has its portion for pressing of the tightening strap 1 equipped with teeth 25. The teeth 25 increase the downforce effect as well as resistance against pulling the tightening strap 1 out after its tightening in the second stage of limb constriction. In its bottom central part, the brake 9 has the inner groove 20, in which there is a compression spring on the brake pivot, the compression spring being of coiled torsion type. One arm of the compression spring is supported against the inner groove 20 of the brake 9, while the second arm is supported against a mortise 11 of the reinforcing crossbar 8.

[0070] Example 2 (not illustrated)

[0071] In one example of the embodiment of the present invention based on Example 1, the bar 12 is in its front part opposite its anchoring on lever pivot 16 equipped with an aperture and a grip strap arranged therein. This enables an easier, i.e. faster grasp of the bar 12 in the second stage of limb constriction.

[0072] Example of individual first aid kit (not illustrated)

[0073] In this specific example of the individual first aid kit of the present invention, the mechanical tourniquets according to Example 1 are attached to the garment in locations which are on each limb close to the trunk. These locations are situated in the groin area of thighs and in the biceps area of arms, i.e. on the garment covering these body areas. Each mechanical tourniquet is attached to the garment permanently, which means that there are several loops on the garment arranged along the circumference of each limb in the above mentioned areas, or there is a textile sleeving sewn onto the garment, the sleeving being interrupted solely at the place of the tightening lock 2. The tightening strap 1 is covered with fabric covering of the same colour asPV 2025-59

[0074] 10

[0075] the gear and equipped with a hook-and-loop fastener. One component of the hook-and-loop fastener is situated on the mechanical tourniquet and the second component of the hook-and-loop fastener is situated on the gear. Nevertheless, the gear as such is not comprised in the individual first aid kit and serves only for firm attachment of the loose end of the tightening strap 1 and of the bar 12, so that a unintended handling of the mechanical tourniquet during an injured person’s movement is prevented as well as situations, in which the mechanical tourniquet gets accidentally caught on a plant. The anchoring surface 23 and the anchoring aperture 24 of the tightening lock body 2 are attached to the garment by textile seams.

[0076] Industrial applicability

[0077] The mechanical tourniquet of the present invention is suited for use in armed forces, where there is a higher risk of combat injury and where it is for security reasons impossible to provide fully fledged first aid on the spot, the main task being to preserve essential life functions of the injured person and to transport the victim to the safe rear for further treatment.
