Description

Technical Field

[0001] The topics currently being discussed generally relate to the field of first aid products, and more specifically to a first aid device for controlling bleeding wounds. Background Technology

[0002] First aid is a routine matter and concern for emergency medical services, such as for paramedics and / or combat soldiers during wartime. Some of the most basic first aid treatments can be performed using an emergency bandage or tourniquet, and in some cases, both may need to be used simultaneously. According to common treatment practices, in the event of mass casualties, the instruction may be to first apply a tourniquet upon discovering a bleeding wound, with the wound only being physically examined after evacuation or once the situation is under control. This may result in the tourniquet being removed and replaced with an emergency bandage as a means of applying direct pressure to the wound. On the other hand, in some situations, an emergency bandage may be applied first, and if this is insufficient to control the bleeding, a tourniquet may need to be used further. Summary of the Invention

[0003] The subject matter currently disclosed describes in detail below various devices for controlling blood flow in a bleeding (hemorrhagic) wound, according to the different aspects mentioned.

[0004] Therefore, due to a bleeding wound, a patient may lose a significant amount of blood, which can lead to hypovolemic (hemorrhagic) shock and even death. The decision to use a tourniquet or an emergency bandage as a means of applying direct pressure is based on various criteria, such as the severity of the injury, the need for amputation, environmental conditions, the circumstances of the event, and the number of patients requiring simultaneous treatment.

[0005] While the primary purpose of an emergency bandage is to stop blood flow to a traumatic bleeding wound by applying it directly to the wound, the primary purpose of a tourniquet is to completely or almost completely block arterial blood flow to the wound by applying it near the wound rather than on it. Each of these first-aid devices, an emergency bandage and a tourniquet, is typically applied according to different treatment protocols, depending on the aforementioned predetermined criteria. Each of these devices is usually provided and used separately from the other.

[0006] According to these protocols, an emergency bandage should typically be used to apply direct pressure to the wound to absorb blood, and a tourniquet should be used to control the bleeding according to a predetermined standard, for example, when the wound does not respond adequately to the emergency bandage, or in the case of severe limb bleeding, in which case additional intervention is required.

[0007] According to a first aspect of the currently disclosed subject matter, a first aid device for controlling a bleeding wound on a limb is provided, the first aid device comprising, at least in use: An emergency bandage having a blood-absorbing portion and a center point, and at least one bandage strip at least indirectly connected to the blood-absorbing portion and configured to securely attach the blood-absorbing portion to the limb, wherein the blood-absorbing portion is located above the wound; and A tourniquet having a tourniquet longitudinal axis and connected to the emergency bandage, such that, in a plan view of the device, the tourniquet longitudinal axis is spaced from the center point of the emergency bandage by a distance required to restrict blood flow to the wound, the tourniquet having at least one tourniquet strip extending along the tourniquet longitudinal axis and configured to securely attach the tourniquet to the limb.

[0008] The term "center point" in the specification and claims refers to a geometric center, that is, the arithmetic mean position of all points of the blood absorption portion.

[0009] The first-aid device of the first aspect is a combination of an emergency bandage and a tourniquet, integrally disposed in a single device, side-by-side close to each other, and, according to a particular example, detachable if necessary. The first-aid device of the first aspect offers various advantages over other known first-aid devices. For example, the device provides flexibility for all types and severities of bleeding wounds, enabling a gradual and controlled (without risk to the patient) and efficient and rapid switch from a high-severity level to a non-severity level (i.e., performing a transition) from a non-severe to a severe level, and vice versa. Due to its simplicity of operation and the ability to switch between the emergency bandage and the tourniquet in the manner described above, the device can be operated by a non-professional operator (i.e., a non-medical or non-caregiver).

[0010] The structure of the first-aid device, particularly the distance between the center points of the tourniquet and the emergency bandage, allows for proper positioning of the tourniquet relative to the wound, and closer to the heart in some limbs. In cases of severe bleeding and life-threatening emergencies, the effective and proper placement of a tourniquet is crucial for stopping the bleeding and stabilizing an injured person until they can receive appropriate medical care. Therefore, the first-aid device described in the first aspect can aid in this proper positioning.

[0011] In addition, in severe cases where a tourniquet must be used immediately, an emergency bandage can still be used to absorb blood from the bleeding wound until the tourniquet is fully applied to the limb.

[0012] Furthermore, the emergency bandage applied to the limb can be removed from the limb via a controlled method (i.e., switching). In this case, the emergency bandage can prevent the adverse effects of uncontrolled blood flow, just like other known tourniquets.

[0013] Therefore, the combination of the emergency bandage and the tourniquet in a first aid device allows for both individual and simultaneous use, taking advantage of their respective functions and benefits, and improving the treatment of the patient.

[0014] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the first-aid device of the currently disclosed subject matter.

[0015] The blood-absorbing portion may include any hemostatic wound dressing configured to absorb large amounts of blood (e.g., 400-600cc).

[0016] The distance between the longitudinal axis of the tourniquet and the center point of the emergency bandage may be at least 3 cm, more specifically, about 4 cm, as required by common emergency treatment protocols.

[0017] The center point of the blood-absorbing portion may be configured to be at least partially positioned above the center of the bleeding wound to apply direct pressure thereon.

[0018] The emergency bandage may have a bandage longitudinal axis that is at least partially parallel to the tourniquet's longitudinal axis, and the bandage longitudinal axis may extend through the center point.

[0019] The at least one bandage strip may extend along the longitudinal axis of the bandage.

[0020] In a plan view of the device, the longitudinal axis of the tourniquet may be spaced apart from the blood absorption portion.

[0021] According to one particular example, the tourniquet is detachable from the emergency bandage. According to that example, the emergency bandage may further include at least one bandage interconnection member, and the tourniquet may include at least one tourniquet interconnection member, both providing the attachment and separation between the emergency bandage and the tourniquet.

[0022] According to another example, the tourniquet and emergency bandage can be attached to each other so that they share a common housing, in the form of a sleeve, a covering layer or any other flexible fabric.

[0023] At least one of the bandages is more elastic than the tourniquet. The bandage strip may be made of a flexible material to prevent it from being overly tight on the limb, thereby unintentionally restricting blood flow to the rest of the limb and unintentionally acting as a tourniquet. The tourniquet may be held in the other hand and is made of a very rigid material, allowing it to be effectively secured to the limb and quickly restrict the flow of blood to the wound as needed.

[0024] The emergency bandage may further include: at least one lockable element mounted on the bandage strip; and at least one bandage locking port, which is at least indirectly attached to the blood-absorbing portion and configured to be at least attached to the bandage locking element, thereby securing the blood-absorbing portion to the wound and applying a first bandage pressure to the blood-absorbing portion.

[0025] The blood-absorbing portion may have a first absorbent surface and an opposing second absorbent surface, the first absorbent surface being configured to absorb blood from the wound.

[0026] The bandage strip may have a first and a second bandage-locking element mounted thereon and spaced apart from each other along the length of the bandage strip. The emergency bandage may have two bandage-locking ports at least indirectly disposed on the second absorbent surface, one of which is configured to attach to the first bandage-locking element to secure the blood-absorbing portion to the wound and apply a first bandage pressure to the blood-absorbing portion, and the other of the bandage ports is configured to attach to the second bandage-locking element to allow additional bandage pressure to be applied to the blood-absorbing portion.

[0027] The emergency bandage may further include a covering layer disposed on the second absorbent surface. The bandage strips may be directly connected to the covering layer and indirectly connected to the blood-absorbing portion.

[0028] The emergency bandage may also include a pressure-applying member disposed at least partially between the first absorbent surface and the covering layer, and configured to apply direct pressure to the wound when securing the bandage strips while the blood-absorbing portion is securely attached to the wound.

[0029] According to a particular example, the pressure-applying member may be disposed at least partially between the second absorbent surface and the covering layer.

[0030] The tourniquet may further include: a tourniquet locking port configured to securely attach the tourniquet strip to the limb and apply a first tourniquet pressure to the limb; and a lever fastening mechanism configured to be used after the first tourniquet pressure is applied to fasten the tourniquet.

[0031] The lever fastening mechanism may include an elongated rotatable element, and the tourniquet may further include an elongated sleeve having two opposing longitudinal boundaries extending along the longitudinal axis, such that the elongated rotatable element is manipulated between a first initial state and at least a second pressure-applied state, wherein in the first initial state, in a plan view of the tourniquet, the lever fastening mechanism is disposed between the plurality of longitudinal boundaries.

[0032] The aforementioned position of the rotatable element in its initial state is preferable to another position where several portions of the rotatable component extend beyond one or two longitudinal boundaries, because it allows the tourniquet to be more compact before use without the need for the tourniquet's interfering proximal wrapping. For example, when an emergency bandage is attached to the tourniquet, the aforementioned position of the rotatable element in its initial state does not interfere with the operation of the emergency bandage.

[0033] According to a second aspect of the currently disclosed subject matter, an emergency bandage for controlling a bleeding wound is provided, having a bandage longitudinal axis, the emergency bandage comprising: A blood absorption portion having a center point, the blood absorption portion having a first absorption surface and an opposing second absorption surface, the first absorption surface being configured to absorb blood from a wound; A bandage strip, at least indirectly connected to the blood-absorbing portion and having first and second bandage lockable elements mounted thereon and spaced apart from each other along the length of the strip; and Two bandage locking ports are disposed at least indirectly on the second absorbent surface. One of the plurality of bandage ports is configured to attach to the first bandage locking element to secure the blood-absorbing portion to the wound and apply a first bandage pressure to the blood-absorbing portion. The other of the plurality of bandage ports is configured to attach to the second bandage locking element to allow an additional bandage pressure to be applied to the blood-absorbing portion.

[0034] The second aspect of the emergency bandage has a dual locking mechanism provided by the bandage locking port and its respective bandage port. The dual locking mechanism allows for better control of the direct pressure applied by the emergency bandage to the bleeding wound. In other words, to apply a certain level of direct bandage pressure, the first bandage locking port and its corresponding first bandage port are used; if the bleeding does not stop, an additional level of direct bandage pressure can be applied by using the second bandage locking port and its corresponding second bandage port.

[0035] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the emergency bandage of the second aspect of the currently disclosed subject matter.

[0036] The bandage locking port can be positioned along the longitudinal axis of the bandage.

[0037] The bandage locking port can be located on the opposite side of the center point.

[0038] The emergency bandage may have a secondary emergency bandage axis, which is perpendicular to the longitudinal axis of the bandage and extends through the center point, such that the two bandage locking ports are located on opposite sides of the secondary emergency bandage axis.

[0039] The two bandage locking ports can be connected to each other by a bridging member, together with the bridging member forming a dual-port configuration, which is substantially positioned above the center point in a plan view of the emergency bandage.

[0040] The emergency bandage may further include a cover layer disposed on the second absorbent surface, such that the two bandage locking ports are disposed on the cover layer.

[0041] The emergency bandage may further include a pressure-applying member disposed at least partially between the first absorbent surface and the covering layer, and applying an additional direct pressure when the additional bandage pressure is applied.

[0042] The pressure applying member can be connected to the bridging member.

[0043] The two bandage locking ports can have a similar structure and can be back-to-back with each other.

[0044] The first and second lockable bandage elements can be positioned in opposite directions relative to the bandage strip. According to the example, after the bandage is wrapped around the limb and the first bandage port is connected to the first lockable bandage element, the first bandage pressure can be generated by pulling the bandage in one direction. Then, a free portion of the bandage, including the second lockable bandage element, can be used to wrap around the limb in the opposite direction and attach the second bandage port to the second lockable element. After this attachment, the additional bandage pressure can be generated by pulling the bandage strip in the opposite direction. This positioning of the first and second lockable bandage elements helps to properly connect them to their respective first and second bandage ports and to use them in the correct order.

[0045] The first and second bandage lockable elements can slide along the bandage strips. This allows them to be fitted around the periphery of any particular limb.

[0046] The bandage strip may be at least partially elastic.

[0047] The emergency bandage may further include at least one bandage interconnection member, which is mounted onto the emergency bandage.

[0048] According to a third aspect of the currently disclosed subject matter, an emergency bandage is provided for controlling a bleeding wound, said emergency bandage comprising: A blood-absorbing portion having a first absorbent surface and an opposing second absorbent surface, the first absorbent surface being configured to face and absorb blood from a wound; A covering layer is disposed on the second absorbent surface; At least one bandage strip, which is at least indirectly connected to the blood-absorbing portion and configured to securely attach the blood-absorbing portion to the wound; and A pressure-applying member is disposed at least partially between the first absorbent surface and the covering layer, and is configured to apply direct pressure to the wound when the blood-absorbing portion is applied to the wound and when the bandage strip is secured.

[0049] The pressure-applying member is configured to apply direct pressure to the wound when the blood-absorbing portion is attached to the wound, thereby helping to stop the bleeding from the wound.

[0050] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the emergency bandage of the third aspect of the currently disclosed subject matter.

[0051] The pressure-applying member may be disposed at least partially between the second absorbent surface and a bottom surface of the cover layer.

[0052] According to a particular example, the pressure-applying member may be disposed entirely between the second absorbent surface and the cover layer.

[0053] The position of the pressure-applying member between the blood-absorbing portion and the covering layer, for example, not above a top surface of the covering layer, causes the pressure-applying element to be very close to the wound, thereby improving its function in applying the direct pressure to the wound and helping to stop the bleeding.

[0054] According to a particular example, the pressure-applying member may protrude from the bottom surface of the cover layer.

[0055] The blood absorption portion may have a center point, such that the pressure applying member is at least partially positioned above the center point.

[0056] The pressure-applying member can typically apply pressure to the second absorbent surface and bend the blood-absorbing portion outward. The structure can provide a user with indication of the position of the pressure-applying member and help them correctly locate the blood-absorbing portion, particularly since the pressure-applying member is located directly above the bleeding wound.

[0057] The pressure-applying member may have a rigidity greater than that of the blood absorption portion, and the pressure-applying element may be made of a rigid material (e.g., plastic, metal, wood, etc.).

[0058] The pressure-applying member may have a pressure surface configured to face the second absorbent surface. Having a smooth pressure surface may be important for applying the direct pressure evenly to the wound without damaging the material of the blood-absorbing portion.

[0059] According to a particular example, the pressure applying member may have a rear surface opposite the pressure surface, and the rear surface may be substantially flat, while the pressure surface may be spherical.

[0060] The emergency bandage may further include: at least one bandage-locking element mounted on the bandage strip; and at least one bandage-locking port disposed on the cover layer and configured to connect to the at least one lockable bandage element, thereby securing the blood-absorbing portion to the wound and applying a first direct pressure to the wound. The first direct pressure is applied at least partially by the pressure-applying member.

[0061] The at least one bandage locking port can be directly connected to the pressure application member.

[0062] The at least one bandage-locking element may be composed of first and second bandage-locking members, which are mounted and spaced apart from each other along the length of the bandage strip. One of the plurality of bandage locking ports is configured to attach to the first bandage locking element to secure the blood-absorbing portion to the wound, and the other of the plurality of bandage ports is configured to attach to the second bandage-locking element to apply additional direct pressure to the wound. This additional direct pressure is applied at least partially by the pressure-applying member. Therefore, the total pressure applied to the wound is the sum of the first direct pressure and the additional direct pressure.

[0063] The two bandage locking ports can be directly connected to the pressure application component.

[0064] The two bandage locking ports can be connected to each other via a bridging member, forming a dual-port configuration together with the bridging member. The pressure-applying member can be connected to the bridging member. The dual-port configuration can be made of a rigid material and is designed to effectively transmit the pressure generated by the fastening bandage strip to the pressure-applying member.

[0065] The emergency bandage may further include at least one bandage interconnection member, which is mounted on the emergency bandage and configured to detachably attach a tourniquet interconnection member of a tourniquet thereto.

[0066] According to a fourth aspect of the currently disclosed subject matter, an emergency bandage is provided that can be used with a tourniquet to serve at least in controlling a bleeding wound, said emergency bandage comprising: A blood-absorbing portion configured to absorb blood from the wound, at least one bandage strip being at least indirectly connected to the blood-absorbing portion and configured to securely attach the blood-absorbing portion to the wound, the blood-absorbing portion having a first absorbent surface and an opposing second absorbent surface, the first absorbent surface being configured to face the wound; and At least one bandage interconnection member is mounted to the emergency bandage and configured to be detachably attached to the tourniquet.

[0067] While the primary purpose of an emergency bandage is to stop blood flow to a traumatic bleeding wound by applying it directly to the wound, the primary purpose of a tourniquet is to completely or almost completely stop arterial blood flow to the wound by applying it close to but not exceeding the wound. Each of these first-aid devices, an emergency bandage and a tourniquet, typically depends on the aforementioned predetermined standards, depending on the specific treatment protocol. Each of these devices is usually provided and used separately from the other.

[0068] According to these protocols, emergency bandages are typically used to apply direct pressure to the wound to absorb blood, while tourniquets are used to control bleeding from the wound according to a predetermined standard, for example, when the wound does not respond adequately to the emergency bandage, or in cases of severe limb bleeding where additional intervention is required.

[0069] Therefore, attaching the tourniquet to the emergency bandage allows the emergency bandage to be converted into the first aid device, comprising an emergency bandage and a tourniquet in a single device, allowing the application of the above-mentioned scheme according to the severity of the wound, and allowing a gradual and controlled (without endangering the patient) and efficient and rapid switch from the emergency bandage to the tourniquet, and vice versa.

[0070] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the emergency bandage of the fourth aspect of the currently disclosed subject matter.

[0071] The emergency bandage may further include a cover layer disposed on the second absorbent surface, to which the at least one bandage interconnecting member may be mounted.

[0072] The emergency bandage may also include a pressure-applying member disposed at least partially between the first absorbent surface and the covering layer, and configured to apply direct pressure to the wound when securing the blood-absorbing portion to the wound.

[0073] The emergency bandage may have a longitudinal axis along which at least one bandage strip extends, and the covering layer may have two opposing sides extending along the longitudinal axis of the bandage, such that the bandage interconnecting members form part of one of the sides.

[0074] The bandage interconnecting member may be spaced apart from at least one bandage strip.

[0075] The bandage interconnecting member can be elongated so that it corresponds in shape to the tourniquet interconnecting member.

[0076] At least one bandage interconnect member can also be configured to detachably connect an additional bandage interconnect member to a second emergency bandage.

[0077] The bandage strips may be at least partially elastic.

[0078] The emergency bandage may further include: at least one lockable bandage element mounted on the at least one bandage strip; and at least one bandage locking port, which is at least indirectly connected to the blood-absorbing portion and configured to attach to the at least one bandage locking element, thereby securing the blood-absorbing portion to the wound and applying a first direct pressure to the wound.

[0079] The at least one bandage-locking element may be composed of first and second bandage-locking components, which are mounted and spaced apart from each other along the length of the bandage strip; and wherein the at least one bandage-locking port is formed by two bandage-locking holes provided on the covering layer. One of the bandage-locking ports may be configured to attach to the first bandage-locking element to secure the blood-absorbing portion to the wound, and the other bandage port may be configured to attach to the second bandage-locking element to apply additional direct pressure to the wound.

[0080] According to the fifth aspect of the currently disclosed subject matter, a tourniquet is provided that can be used with an emergency bandage to constitute a first aid device, at least in use, for controlling a bleeding wound on a limb, said tourniquet having a tourniquet longitudinal axis and comprising: At least one tourniquet strip extending along the longitudinal axis of the tourniquet and configured to securely attach the tourniquet to the limb; and At least one tourniquet interconnection member is mounted on the tourniquet and configured to be detachably connected to a bandage interconnection member of the emergency bandage.

[0081] While the primary purpose of an emergency bandage is to stop blood flow to a traumatic bleeding wound by applying it directly to the wound, the primary purpose of a tourniquet is to completely or almost completely stop arterial blood flow to the wound by applying it close to but not exceeding the wound. Each of these first-aid devices, an emergency bandage and a tourniquet, is typically applied according to the aforementioned predetermined standards, depending on the specific treatment protocol. Each of these devices is usually provided and used separately from the other.

[0082] According to these protocols, an emergency bandage should typically be used to apply direct pressure to the wound to absorb blood, and a tourniquet should be used to control the bleeding from the wound according to a predetermined standard, for example, when the wound does not respond adequately to the emergency bandage, or in the case of severe limb bleeding, in which case additional intervention is required.

[0083] Therefore, the connection between the emergency bandage and the tourniquet allows the emergency bandage to be converted into the first aid device, comprising a tourniquet and an emergency bandage in a single device, allowing the application of the above-described scheme according to the severity of the wound, switching from the emergency bandage in a gradual and controlled manner (without endangering the patient) and in a highly efficient and rapid manner, and vice versa.

[0084] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the tourniquet of the fifth aspect of the currently disclosed subject matter.

[0085] The tourniquet may also include an elongated sleeve through which at least a portion of the tourniquet strip passes and to which at least one tourniquet interconnecting member is mounted.

[0086] The sleeve may include a side portion, wherein the at least one tourniquet interconnecting member forms a part thereof, such that, in a plan view of the tourniquet, the tourniquet interconnecting member is spaced apart from the tourniquet strip.

[0087] The tourniquet interconnecting member may be elongated so as to correspond in shape to the bandage interconnecting member.

[0088] The tourniquet may further include: a tourniquet locking port configured to securely attach the tourniquet strip to the limb and apply a first tourniquet pressure to the limb; and a lever fastening mechanism configured to be used after applying the first tourniquet pressure to fasten the tourniquet and apply an additional tourniquet pressure to the limb. The additional tourniquet pressure may be a pressure that completely restricts blood flow to the wound.

[0089] The lever fastening mechanism may include an elongated rotatable element connected to the tourniquet strip. The elongated rotatable element can rotate between a first initial state and at least a second pressure-applied state.

[0090] The tourniquet may further include an elongated sleeve having two opposing longitudinal boundaries extending along the longitudinal axis, such that the elongated rotatable element is manipulated between a first initial state, the lever fastening mechanism being disposed in the first initial state in a plan view of the tourniquet.

[0091] The aforementioned position of the rotatable element in the initial state is preferable to another position where the portion of the rotatable component extends beyond one or two longitudinal boundaries, because it allows the tourniquet to be more compact before use with the rotatable element, without the need for the tourniquet's interfering proximal wrapping. For example, when an emergency bandage is attached to the tourniquet, the aforementioned position of the rotatable element in the initial state does not interfere with the operation of the emergency bandage.

[0092] According to a sixth aspect of the currently disclosed subject matter, a tourniquet is provided, the tourniquet having a tourniquet longitudinal axis and configured for controlling a bleeding wound on a limb, the tourniquet comprising: A slender sleeve having two opposing longitudinal boundaries extending along the longitudinal axis of the tourniquet, the sleeve having a first sleeve surface and a second sleeve surface, the first sleeve surface being configured to face the limb, and the second sleeve surface including an access point; A tourniquet strip, which extends at least partially within the sleeve along the longitudinal axis of the tourniquet; A tourniquet locking port for securely attaching the tourniquet strip to the limb; and A slender, rotatable element is connected to the tourniquet strip via the access point. The rotatable element rotates at the access point together with a portion of the tourniquet strip in an initial state (wherein the rotatable element is disposed between the plurality of longitudinal boundaries in a plan view) and at least in a pressure-applied state.

[0093] The aforementioned position of the rotatable element in the initial state is preferable to another position where the portion of the rotatable component extends beyond one or two longitudinal boundaries, because it allows the tourniquet to be more compact before use without the need for the tourniquet's interfering proximal wrapping. For example, when an emergency bandage is attached to the tourniquet, the aforementioned position of the rotatable element in the initial state does not interfere with the operation of the emergency bandage.

[0094] Any one or more of the following features, designs, and configurations may be incorporated, either independently or in combination, into the tourniquet of the sixth aspect of the currently disclosed subject matter.

[0095] The tourniquet strip may be equipped with a tourniquet locking element configured to be connected to the tourniquet locking port.

[0096] The attachment of the tourniquet lockable element to the tourniquet locking port is configured to securely attach the tourniquet strip to the limb and apply a first tourniquet pressure to the limb, and the elongated rotatable element (forming a lever fastening mechanism) is configured for use after applying the first tourniquet pressure to fasten the tourniquet strip and applying an additional tourniquet pressure to the limb. The additional tourniquet pressure may be a pressure that completely restricts blood flow to the wound.

[0097] The tourniquet locking element can slide along the tourniquet.

[0098] The elongated rotatable element may have an elongated longitudinal axis, such that in the initial state, the elongated rotatable element longitudinal axis is substantially parallel to the tourniquet longitudinal axis.

[0099] The elongated rotatable element may have a longitudinal axis and a length extending along the longitudinal axis. The length may be greater than a distance between the plurality of longitudinal boundaries.

[0100] The tourniquet may further include a fixing member at least partially disposed on the sleeve and configured to releasably lock the elongated rotatable element under one or more of the pressure applied states, the rotatable element being disposed between the plurality of longitudinal boundaries of the sleeve.

[0172] The currently disclosed subject matter, according to the different aspects described above, relates to various devices for controlling blood flow in a bleeding (hemorrhagic) wound.

[0173] First, refer to the attached diagram. Figure 1A-1F And 2A-2D, which show an example of a first aid device of a currently disclosed subject, usually denoted as 1.

[0174] The emergency medical device 1 is configured to control one hand 2 of a patient (e.g., ...). Figure 1E A bleeding wound on a limb (as shown in the image) 3.

[0175] The first aid device 1 includes an emergency bandage 10 and a tourniquet 50 attached to each other, which together form the first aid device 1.

[0176] Depending on the severity of the wound, such as the rate of blood loss and the number of patients requiring simultaneous treatment, the patient may lose too much blood, potentially leading to amputation of a limb or even death. In these cases, the emergency bandage 10 and / or the tourniquet 50 are required to control or even stop blood flow.

[0177] While the primary purpose of the emergency bandage 10 is to apply direct pressure to the bleeding wound 3 by direct application, the primary purpose of the tourniquet 50 is to completely or almost completely restrict blood flow to the bleeding wound 3 by placing it at a predetermined distance from it. Each of these first-aid devices (i.e., the emergency bandage 10 and the tourniquet 50) is typically applied according to different treatment protocols and the severity of the wound, and unlike the subject matter currently disclosed, each of these devices is typically provided and used separately from the others.

[0178] The emergency bandage 10 is configured to apply direct pressure to the bleeding wound 3 and absorb the blood therebetween, and the tourniquet 50 is configured to control restricted blood flow from the bleeding wound 3 if it does not respond adequately to the emergency bandage 10 or if additional intervention is required.

[0179] The first aid device 1 is a combination of the emergency bandage 10 and the tourniquet 50, integrally disposed in a single device and adjacent to each other side-to-side. According to a specific example, the emergency bandage 10 and the tourniquet 50 can be separated from each other, for example, to replace a used emergency bandage 10 with a new one, or when the tourniquet 50 needs to be positioned and applied, due to various medical requirements, with the hand 2 located at a distance from the emergency bandage 10. The first aid device 1 of the currently disclosed subject matter offers various advantages over other known first aid devices. For example, the first aid device 1 provides flexibility for use with bleeding wounds of all severity, and the first aid device 1 can switch from non-severe to severe wounds, and vice versa, in a progressive and controlled manner, without endangering the patient, and efficiently and rapidly. Due to its simplicity of operation and the ability to switch between using the emergency bandage 10 and the tourniquet 50 in the manner described above, the first aid device 1 can be operated by a non-professional user (i.e., not a doctor or a nurse).

[0180] The structure and function of the emergency bandage 10 will now be described in detail. According to this embodiment, it is a hemostatic wound dressing configured to absorb a large amount (e.g., about 500 cc) of blood from the bleeding wound 3. The blood-absorbing portion 20 has a first absorbent surface 24, an opposing second absorbent surface 26, and a center point 22 (preferably see...). Figure 1B , 2A(and 2B), the first absorbent surface 24 is configured to face and contact the bleeding wound 3, and the center point 22 is located at the geometric center, i.e., the center of its width and length. The center point 22 is configured to be located above the center of the bleeding wound 3 in order to apply direct pressure thereon, as described below.

[0181] The emergency bandage 10 further includes a covering layer 30 and a bandage strip 40. The covering layer 30 is disposed on and connected to the second absorbent surface 26, and the bandage strip 40 is connected to the covering layer 30. The covering layer 30 has a top surface 31a and a bottom surface 31b.

[0182] The bandage strip 40 is configured to securely attach the blood-absorbing portion 20 and its covering layer 30 to the hand 2, wherein the first absorbent surface 24 of the blood-absorbing portion 20 is positioned on the bleeding wound 3.

[0183] The emergency bandage has a bandage longitudinal axis X1 extending through the center point 22, and the bandage strip 40 extends along the bandage longitudinal axis X1.

[0184] The bandage strip 40 also has a dual-port 32, which includes a first bandage locking port in the form of a first hook 34, a second bandage locking port in the form of a second hook 36, and a bridging member 35 interconnecting therebetween. The dual-port 32 is disposed on and connected to the top surface 31a of the cover layer 30, such that the first hook 34 and the second hook 36 are arranged along the longitudinal axis X1 of the bandage. The first hook 34 and the second hook 36 have a similar structure and face away from each other.

[0185] The first hook 34 and the second hook 36 are located on opposite sides of the center point 22, wherein the second emergency bandage axis X3 is perpendicular to the longitudinal axis of the bandage and extends between them.

[0186] The emergency bandage 10 also has a pressure-applying member 47 disposed between the second absorbent surface 26 and the bottom surface 31b, and located above the center point 22. The pressure-applying member 47 is connected to the bottom surface 31b by a screw 38 (e.g., ...). Figure 2B (As shown). The screw 38 extends through the cover layer 30 and connects between the bridging member 35 and the pressure applying member 47 of the dual-port 32.

[0187] The pressure-applying member 47 is configured to apply direct pressure to the bleeding wound 3 once the bandage strip 40 is secured when the blood-absorbing portion 20 is securely installed on the bleeding wound 3, thereby helping to stop bleeding from the bleeding wound 3.

[0188] The position of the pressure-applying member 47 between the blood-absorbing portion 20 and the covering layer 30, and for example not above the top surface 31a of the covering layer 30, causes the pressure-applying member 47 to be very close to the bleeding wound 3, thereby improving its function of applying direct pressure to the wound and helping to stop the bleeding.

[0189] like Figure 2B As shown, the pressure-applying member 47 typically applies pressure to the second absorbent surface 26 and bends the blood-absorbing portion 20 outward. This configuration provides the operator with indication of the position of the pressure-applying member 47 and the center point 22, and helps them to correctly position the blood-absorbing portion 20, and in particular, the pressure-applying member 47 is located directly above the bleeding wound 3.

[0190] The pressure-applying member 47 is made of a rigid material (e.g., plastic, metal, wood, etc.), and its rigidity is, of course, much greater than that of the blood-absorbing portion 20. The dual-port 32 is also made of a rigid material and is configured to effectively transmit the pressure generated by the taut bandage strip 40 to the pressure-applying member 47.

[0191] The pressure-applying member 47 has a hemispherical structure, wherein a circular and smooth pressure surface 48 faces the second absorption surface 26, and a flat rear surface 49 is juxtaposed with the bottom surface 31b. The shape of the pressure surface 48 is important for uniformly applying the direct pressure to the bleeding wound 3 without damaging the material of the blood-absorbing portion 20.

[0192] The bandage strip 40 has a first bandage locking element in the form of a first buckle 42 and a second bandage locking element in the form of a second buckle 44, which are slidably mounted on the bandage strip 40 and spaced apart from each other along the length of the bandage strip 40, i.e., along the longitudinal axis X1 of the bandage. Sliding of the first buckle 42 and the second buckle 44 allows them to be attached to the periphery of any particular limb. The first buckle 42 and the second buckle 44 are positioned in opposite directions relative to the bandage strip 40. This positioning facilitates the proper attachment of the first buckle 42 and the second buckle 44 to their respective first and second hooks, and their use in the correct order, as described below.

[0193] The bandage strip 40 is configured to securely attach the blood-absorbing portion to the hand 2 via a process comprising the following steps (see below). Figure 4A (Detailed Description): In one step, after the bandage strip 40 is wrapped around the hand 2, the first buckle 42 is attached to the first hook 34, and the bandage strip 40 is pulled, thereby applying a first bandage pressure to the blood-absorbing portion 20 and the bleeding wound 3, respectively. In a further step, a free portion of the bandage strip, including the second buckle 44, is used to wrap around the hand 2 in the opposite direction. The second buckle 44 is attached to the second hook 36, and the bandage strip 40 is pulled again in the opposite direction, thereby applying an additional bandage pressure to the blood-absorbing portion and the bleeding wound 3, respectively. The result of this process is a total direct pressure of the first bandage pressure and the additional bandage pressure, which is mainly applied to the bleeding wound 3 by the pressure-applying member 47.

[0194] The dual-locking mechanism provided by the dual-port 32, the first buckle 42, and the second buckle 44 provides better control over the degree of direct pressure applied by the emergency bandage 10 to the bleeding wound 3. In other words, the first hook 34 and its corresponding first buckle 42 are used to apply a certain degree of direct bandage pressure, and if the bleeding does not stop, an additional degree of direct bandage pressure can be applied by using the second hook 36 and its corresponding second buckle 44.

[0195] The tourniquet 50 has a tourniquet longitudinal axis X2 and is attached to the emergency bandage, therefore, in a plan view of the device ( Figure 1B and 1C As shown in the diagram, the distance D1 between the tourniquet's longitudinal axis X2 and the center point 22 of the emergency bandage 10 is used to restrict blood flow to the bleeding wound 3. Furthermore, in a plan view of the first aid device 1, the tourniquet's longitudinal axis X2 is spaced apart from the entire blood-absorbing portion 20.

[0196] The tourniquet 50 has a tourniquet strip 60 that extends along the longitudinal axis X2 of the tourniquet and is configured to securely attach the tourniquet 50 to the hand 2.

[0197] The structure of the first aid device 1 (and particularly the distance D1 between the center point 22 of the tourniquet 50 and the emergency bandage 10) also allows for the correct positioning of the tourniquet 50 relative to the bleeding wound 3, i.e., neither too close nor too far, and on the part of the hand 2 near the heart, i.e., above the bleeding wound 3. Effective positioning of the tourniquet 50 is crucial for controlling bleeding until the injured person receives appropriate medical care. Therefore, the first aid device 1 can assist in this correct positioning.

[0198] Depending on the specific example, the distance D1 can be at least 3 cm, and in this example, D1 is approximately 4 cm, as required by common emergency treatment protocols for tourniquet application. The tourniquet's longitudinal axis X2 is parallel to the bandage's longitudinal axis X1, and the distance between them is also D1.

[0199] Based on the specific examples shown in the diagram, especially Figure 3A and Figure 3B In this configuration, the tourniquet 50 is detachable from the emergency bandage 10. The emergency bandage 10 includes a bandage interconnecting member 12, and the tourniquet 50 includes a tourniquet interconnecting member 52; both are loops providing connection and separation between the emergency bandage 10 and the tourniquet 50. The bandage interconnecting member 12 is elongated, thus corresponding in shape to the tourniquet interconnecting member 52.

[0200] According to another example, the tourniquet and emergency bandage can be attached to each other, so that they share a common shell in the form of a sleeve, a cover layer or any other flexible fabric.

[0201] The bandage interconnect member 12 may also be configured as an additional bandage interconnect member detachably attached to a second emergency bandage. Similarly, the tourniquet interconnect member 52 may also be configured as an additional tourniquet interconnect member detachably attached to a second tourniquet.

[0202] The covering layer 30 has two opposing sides 33a and 33b extending along the longitudinal axis X1 of the bandage, such that the bandage interconnecting member is part of the side 33b. The bandage interconnecting member 12 is spaced apart from the bandage strip 40.

[0203] The tourniquet 50 has an elongated sleeve 70 extending along the longitudinal axis X2 of the tourniquet, through which a portion of the tourniquet strip 60 passes. The sleeve 70 has a side portion 72 to which the tourniquet interconnecting member 52 is mounted, thus, in a plan view of the tourniquet 50, the tourniquet interconnecting member 52 is spaced apart from the tourniquet strip 60. The elongated sleeve 70 also has two opposing longitudinal boundaries 73a and 73b extending on two opposite sides of the tourniquet longitudinal axis X2 and generally parallel to it. The tourniquet interconnecting member 52 includes a portion of boundary 73a.

[0204] The sleeve 70 also has a first sleeve surface 71a configured to face the hand 2 and an opposing second sleeve surface 71b, the opposing second sleeve surface 71b including an access point 83 formed therein (e.g., Figure 2D (As shown) to allow a strip portion 61 of the tourniquet strip 60 to extend through it.

[0205] The tourniquet 50 also has a tourniquet locking port in the form of a tourniquet hook 54. The tourniquet strip has a tourniquet locking element in the form of a spring-loaded buckle 56, which is slidable along the tourniquet strip 60 and configured to attach to the tourniquet hook 54. In order to securely attach the tourniquet strip 60 to the hand 2, the spring-loaded buckle 56 must be attached to the tourniquet hook 54, and a free end of the tourniquet strip 60 must be pulled to apply a first tourniquet pressure to the hand 2 and at least partially restrict blood flow to the bleeding wound 3.

[0206] The tourniquet 50 also has a lever fastening mechanism 80 configured for use after the first tourniquet pressure has been applied, and the buckle 56 is attached to the tourniquet hook 54 for further fastening the tourniquet strip 60 and applying an additional tourniquet pressure to the hand 2, thereby completely restricting blood flow to the bleeding wound 3.

[0207] The lever fastening mechanism 80 is configured with an elongated rotatable element 82 having two slits 84, through which the band portion 61 passes through the access point 83 and through the two slits 84, thereby providing a connection between the rotatable element 82 and the tourniquet strip 60.

[0208] The rotatable element 82, together with the strip portion 61, is rotatable between an initial state and one or more pressure-applied states. In the initial state, the rotatable element is positioned between the longitudinal boundaries 73a and 73b in a plan view of the tourniquet. In one or more pressure-applied states, the strip portion 61 and the proximal portion of the tourniquet strip 60 are twisted, thereby further securing the tourniquet strip 60 to the hand 2. The rotatable element 82 rotates counterclockwise from the initial state to the pressure-applied state, further securing the tourniquet strip 60 and applying an additional tourniquet pressure to the hand 2, sufficiently restricting blood flow to the bleeding wound 3. Therefore, the total pressure applied to the hand 2 is the sum of the first tourniquet pressure and the additional tourniquet pressure.

[0209] The aforementioned position of the rotatable element 82 in the initial state is superior to another position where the portion of the rotatable element extends beyond one or two longitudinal boundaries, without interfering with the proximal circumference of the tourniquet 50. For example, when the emergency bandage 10 is attached to the tourniquet 50, the aforementioned position of the rotatable element 82 in the initial state does not interfere with the operation of the emergency bandage.

[0210] The rotatable element 82 may have an elongated rotatable element longitudinal axis X4, such that in the initial state, the elongated rotatable element longitudinal axis X4 is substantially parallel to the tourniquet longitudinal axis X2.

[0211] The elongated rotatable element also has a length dimension D2 extending along the longitudinal axis of the rotatable element. The length dimension D2 is greater than a distance D3 between the longitudinal boundaries 73a and 73b.

[0212] The tourniquet 50 also has a flexible fixing member 85 disposed on and connected to the sleeve 70, and the tourniquet 50 is configured to releasably lock the rotatable element 82 under one or more pressure applications, such that, in a plan view of the tourniquet, the rotatable element 82 is disposed between the plurality of longitudinal boundaries of the sleeve 70.

[0213] The bandage strip 40 is more elastic than the tourniquet strip 60. The bandage strip 40 is made of a flexible material to prevent it from becoming overly tight on the hand 2, thereby unintentionally restricting blood flow to the rest of the hand 2 and unintentionally acting as a tourniquet. On the other hand, the tourniquet strip 60 is made of a very rigid material, enabling it to effectively tighten onto the limb and quickly restrict flow to the bleeding wound 3 as needed. Furthermore, it should be emphasized that the lever-locking mechanism 80 of the tourniquet can generate significantly higher pressure than in any experiment using the emergency bandage.

[0214] like Figure 3B As shown, the tourniquet 50 can be removed from the emergency bandage 10, so that the tourniquet 50 can be installed at a position far away from the emergency bandage according to different treatment plans and the individual conditions of the hand 2.

[0215] Now refer to Figures 4A to 4D To explain how the emergency bandage 10 and the tourniquet 50 can be used individually and / or in combination by the operator of the first aid device 1.

[0216] In particular, now referencing Figure 4A , Figure 4A The step-by-step process of attaching the emergency bandage 10 to the hand 2 is shown.

[0217] like Figure 4AAs shown in step 100, the emergency bandage 10 is placed above the bleeding wound 3, such that the center point 22 and the pressure-applying member 47 are located above a center of the bleeding wound 3. In step 110, the bandage strip 40 is wrapped half a turn relative to the hand 2, and the first buckle 42 is attached to the first hook 34. Then, one free end of the bandage strip 40 is pulled to apply a first bandage pressure to the blood-absorbing portion 20 and the bleeding wound 3. In step 120, the bandage strip 40 is wrapped a full turn relative to the hand 2, such that a portion of the bandage strip 40 is wrapped near the side portion 33a. In step 130, the bandage strip 40 is wrapped an additional full turn relative to the hand 2, such that the remaining portion of the bandage strip 40 is wrapped near the side portion 33b. This positioning of the strips allows the wound to be symmetrically surrounded between the two portions of the strips, thereby effectively treating the wound. In step 140, the second buckle 44 is attached and pulled to the second hook 36, and then a free end of the bandage strip 40 is pulled in the opposite direction to apply additional bandage pressure to the blood-absorbing portion 20 and the bleeding wound 3. The result of this process is a total direct pressure from the first bandage pressure and the additional bandage pressure, which is primarily applied to the bleeding wound 3 by the pressure-applying member 47, while the blood-absorbing portion 20 absorbs blood from the bleeding wound 3. Figure 4A Throughout the process, the tourniquet hook 54 separates from the buckle 56, so the tourniquet 50 is in an inoperative state.

[0218] If in Figure 4A If bleeding from the wound 3 does not stop after the emergency bandage 10 is applied, the tourniquet 50 should be used to completely restrict blood flow to the wound 3. Figure 4B The process is shown in one step.

[0219] Now refer to Figure 4B , Figure 4B Shown in Figure 4A Following this process, a stepwise process is performed to attach the tourniquet 50 to the hand 2 to completely restrict blood flow to the bleeding wound 3.

[0220] When the bleeding from the wound has not stopped, apply Figure 4B The procedure requires the application of the tourniquet 50 to completely restrict blood flow to the bleeding wound 3.

[0221] exist Figure 4B (as well as Figure 4AIn step 140, the emergency bandage 10 is attached to the hand 2 and the tourniquet 50 is removed from it, with the longitudinal axis X2 of the tourniquet spaced apart from the center point 22 of the emergency bandage by the distance D1 to restrict blood flow to the bleeding wound 3.

[0222] In step 150, by attaching the buckle 56 to the tourniquet hook 54 and pulling one free end of the tourniquet strip 60 to securely attach the tourniquet strip 60 to the hand 2, a first tourniquet pressure is applied, at least partially restricting blood flow to the bleeding wound 3. If the bleeding still does not stop, step 160 should be performed. In this position, the rotatable element 82 is in the initial state, wherein the tourniquet strip 60 is not twisted.

[0223] In step 160, the lever fastening mechanism 80 is applied. To this end, the rotatable element 82 is withdrawn from the fixed member 85 to allow rotation, and the rotatable element 82 rotates several times in a counter-clockwise direction. This rotation causes the tourniquet strip 60 to apply additional tourniquet pressure to the hand 2, thereby completely restricting blood flow to the bleeding wound 3.

[0224] In step 170, when the rotation of the rotatable element 82 stops, the rotatable element 82 is in a pressure-applied state, and a corresponding portion of the rotatable element 82 is introduced into the fixing member 85 and thereby locked in this state.

[0225] Now refer to Figure 4C , Figure 4C The step-by-step process of attaching the emergency bandage 10 to the hand 2 is shown, wherein a first bandage is applied with pressure and the tourniquet 50 is fully attached. This process is used when the bleeding wound is of very high severity, and the initial operator decides whether to use the tourniquet 50 to completely restrict the blood flow.

[0226] exist Figure 4C At the start of the process, the following was applied. Figure 4A In the process described above, steps 100 and 110 involve placing the first aid device 1 on the hand 2 and initiating blood absorption from the bleeding wound until the tourniquet is fully applied to the hand 2. However, instead of steps 120, 130, and 140, the operation omits the step of fully applying the tourniquet 50 to the hand 2. In particular, step 180 is similar to step 150, step 190 is similar to step 160, and step 200 is similar to step 170. Figure 4CWhen the process is completed, the blood flow to the bleeding wound 3 is completely suppressed, and the emergency bandage includes the absorbed blood flow. Figure 4C The process thus demonstrates another advantage of the subject matter currently disclosed, according to which, although the tourniquet is primarily used, the emergency bandage is also used to help absorb blood during the application of the tourniquet.

[0227] Now refer to Figure 4D This shows a reduction Figure 4B The procedure involves applying additional tourniquet pressure, while the emergency bandage is fully attached to the hand, with additional bandage pressure applied to it. Figure 4D The procedure described herein is typically performed by a professional operator (e.g., a doctor) in a hospital to remove the tourniquet 50 from the hand 2 in a controlled manner, but the emergency bandage may also be used.

[0228] Figure 4D Step 200 in the middle is similar to Figure 4C The steps are as follows. At step 200, the first bandage pressure is applied to the bleeding wound, as shown in step 110. However, in step 200, blood flow to the bleeding wound 3 is completely inhibited by the tourniquet 50. In the next step 210, the bandage strip 40 is used to apply the additional bandage pressure. The use of the emergency bandage 10 in step 210 is similar to that in steps 120, 130, and 140.

[0229] In the next step 220, the rotatable element 82 is removed from the fixed member 85 and rotated half a circle clockwise to slowly reduce the additional tourniquet pressure and slowly allow blood to flow through.

[0230] Subsequently, the rotatable element 82 is locked again by the fixing member 85, and the operator should wait for a predetermined period of time. The operator should repeat steps 220 and 230 in a controlled manner until the tourniquet is completely removed, or even removed from the emergency bandage as shown in step 240.
