Description

Technical Field

[0001] The invention relates to the technical field of hemostatic rings, in particular to a foldable hemostatic ring that can be quickly deployed outdoors. Background Art

[0002] During outdoor activities, military operations or emergency rescue, the injured may suffer serious bleeding injuries. In this case, quick and effective hemostasis is the key to saving lives. Traditional hemostasis methods may not be quick or effective enough, so the development of new hemostasis equipment has become a top priority. In particular, an outdoor folding hemostatic ring that can be quickly deployed, simple to operate, and effectively stop bleeding is crucial to saving lives. Hemostatic rings in the prior art are mainly divided into inflatable, cassette, cloth strip, and spin-pressed types. Various types of hemostatic rings differ in their scope of use and characteristics, but they generally have problems such as complex operation and unstable hemostatic effects. And a qualified hemostatic ring needs to take into account factors such as convenient carrying, no external energy dependence, simple operation, and no need for help from others. Therefore, it is very necessary to provide a folding hemostatic ring that can be quickly deployed outdoors.

[0003] However, one of the shortcomings of the related art is that the operation process is complicated and cannot be deployed quickly, and it cannot be operated with one hand. Summary of the invention

[0004] The present invention aims to solve at least one of the above technical problems.

[0005] To solve the above problems, a first object of the present invention is to provide a foldable hemostatic ring that can be quickly deployed outdoors.

[0006] To achieve the first purpose of the present invention, an embodiment of the present invention provides a foldable hemostatic ring for outdoor rapid deployment, which includes: an airbag, which has an expanded state and a contracted state; a tightening assembly, which is connected to the airbag, and the tightening assembly includes: a first tightening piece, which is communicated with the airbag, and the first tightening piece includes: a base, the base is provided with a one-way air inlet pipe, and the one-way air inlet pipe is communicated with the airbag; a gas generator, the gas generator is matched with the base, the gas generator is provided with an air outlet pipe, and the air outlet pipe is matched with the one-way air inlet pipe; at least two second tightening pieces, and the second tightening pieces are detachably connected to the first tightening piece.

[0007] The airbag can be folded in a contracted state, and the clamping assembly is divided into a first clamping member and several second clamping members. This setting enables the hemostatic ring to be folded as a whole, so that the hemostatic ring is small in size and light in weight when not in use, and is easy to carry, and is particularly suitable for outdoor activities, military operations and other occasions. When the airbag is in a contracted state, the user can easily put the hemostatic ring on and place it in a required position. This setting enables the wounded to put it on with one hand in special circumstances to achieve the effect of rapid deployment. Through the detachable connection between the first clamping member and at least two second clamping members, it can be adjusted according to the size and shape of different injured limbs to meet different hemostasis needs. The setting of the one-way air inlet pipe allows the gas to only enter the airbag and not easily flow out, and the wounded can be quickly stopped through the one-way air inlet pipe. The design of the one-way air inlet pipe helps to maintain the pressure in the airbag and prevent the hemostasis effect from being weakened due to leakage. In addition, the airbag can be continuously filled with gas through the one-way air inlet pipe until the pressure reaches the required size. The gas generator can quickly generate gas and directly send it into the one-way air inlet pipe through the air outlet pipe, thereby quickly inflating the airbag. This design eliminates the need for an external gas source, making the hemostasis process faster and more efficient. The overall design can shorten the preparation time and speed up the rescue response. In an emergency, it can achieve the effect of rapid deployment and rapid inflation.

[0008] In the above technical solution, the middle part of the bottom end of the first tightening member is connected to the outside of the airbag; the middle part of the bottom end of the second tightening member is connected to the outside of the airbag.

[0009] By only connecting the middle part, when the airbag is expanded or the first and second tightening members are adjusted, it is possible to avoid tearing of the connection caused by excessive connection parts when the shape changes. By setting the first and second tightening members, the size of the hemostatic ring can be flexibly changed to adapt to different use parts.

[0010] In any of the above technical solutions, the tightening assembly is provided with a locking assembly, which includes: a first locking piece, which is arranged on the first tightening piece and the second tightening piece; a second locking piece, which is arranged on the first tightening piece and the second tightening piece, and the second locking piece is arranged opposite to the first locking piece, and the second locking piece cooperates with the first locking piece.

[0011] The cooperation between the first locking member and the second locking member can provide a more stable connection when tightening, ensuring that the hemostatic ring will not loosen due to the movement of the limbs or the influence of external forces in an emergency, thereby avoiding the deterioration of the condition of the injured person due to the failure of hemostasis. The design of the locking assembly allows the user to quickly lock the first tightening member and the second tightening member together, so as to quickly apply pressure to stop bleeding, reduce the operation time, improve efficiency and achieve the purpose of rapid deployment. Through the cooperation of the first locking member and the second locking member, a certain degree of adjustment ability can also be provided, so that the hemostatic ring can adapt to limbs of different sizes. And when it is necessary to relax the pressure regularly, by separating the second locking member from the first locking member, the effect of reducing pressure can be achieved, and the operation can be performed by only one person.

[0012] In any of the above technical solutions, a first locking buckle is provided at one end of the first locking member, and a second locking buckle is provided at one end of the second locking member.

[0013] Through the cooperation between the first locking buckle and the second locking buckle, the first locking member and the second locking member can be stably connected together, thereby connecting the first tightening member and the second tightening member, and the second tightening member and the second tightening member to each other.

[0014] In any of the above technical solutions, the clamping assembly has a locked state and an unlocked state. In the locked state, the first lock buckle abuts against the second lock buckle; in the unlocked state, the first lock buckle is away from the second lock buckle.

[0015] Since the abutment or separation action of the first lock buckle and the second lock buckle is simple and intuitive, it can ensure that the user can operate correctly and quickly even in a tense or non-professional first aid environment. In the locked state, the first lock buckle and the second lock buckle abut against each other, providing a more stable connection, ensuring that the hemostatic ring will not loosen due to limb movement or external forces in an emergency. The stable performance in the locked state prevents the hemostatic ring from accidentally loosening during use, thereby avoiding the deterioration of the condition of the injured person due to hemostasis failure. When the clamping assembly is in the unlocked state and the airbag is in the contracted state, the hemostatic ring as a whole is in a foldable state, which can be folded and stored without taking up space, making it more convenient to carry.

[0016] In any of the above technical solutions, the gas generator has an inner cavity, in which the first reaction substance and the second reaction substance are contained, and an isolation layer is provided in the inner cavity, which isolates the first reaction substance and the second reaction substance from each other.

[0017] By separating the reactants through an isolation layer, it is possible to prevent them from contacting and reacting in advance when gas generation is not required. The design of the isolation layer helps to maintain the stability of the reactants, extend the validity period of the gas generator, and ensure that it can work reliably when needed. The isolation layer has a certain upper pressure limit. When a reaction is required, the gas generator is shaken with a certain force to rupture the isolation layer, so that the first reactant and the second reactant contact each other, react, and quickly generate a large amount of gas, which is directly sent into the one-way air inlet pipe through the outlet pipe and then enters the airbag. The first reactant and the second reactant react in the gas generator, and the gas generator and the airbag are separated by a base. This setting can effectively prevent the large amount of heat generated when the first reactant and the second reactant react cause harm to the user. When in use, the operator only needs to trigger the mixing mechanism to automatically complete the inflation process, which simplifies the operation process, reduces the complexity of use, and improves the efficiency of use in emergency situations.

[0018] In any of the above technical solutions, the gas generator includes: a connecting part, which is connected to the base; and a separating part, which is connected to the connecting part; wherein the isolation layer is located at the connection between the connecting part and the separating part.

[0019] By setting the gas generator into a separation part and a connection part, the connection part is connected to the base, and the isolation layer is set at the connection between the separation part and the connection part, the separation part is movable, and the isolation layer can be broken by the movable separation part, thereby making the first reaction substance react with the second reaction substance to achieve the effect of inflating the airbag.

[0020] In any of the above technical solutions, the first reaction substance is acetic acid and the second reaction substance is baking soda.

[0021] Acetic acid reacts quickly with baking soda and produces enough gas. The produced substances are also safe enough and will not produce any pollutants. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0026] like Figure 1 , Figure 3 as well as Figure 4 As shown, an embodiment of the present invention provides a foldable hemostatic ring for outdoor rapid deployment, which includes: an airbag 100, the airbag 100 has an expanded state and a contracted state; a tightening assembly 200, the tightening assembly 200 is connected to the airbag 100, and the tightening assembly 200 includes: a first tightening member 210, the first tightening member 210 is connected to the airbag 100, and the first tightening member 210 includes: a base 211, the base 211 is provided with a one-way air inlet pipe 211a, and the one-way air inlet pipe 211a is connected to the airbag 100 is connected; a gas generator 212, the gas generator 212 cooperates with the base 211, the gas generator 212 is provided with an outlet pipe 212b, the outlet pipe 212b cooperates with the one-way air inlet pipe 211a; at least two second tightening members 220, the second tightening member 220 is detachably connected to the first tightening member 210; the middle part of the bottom end of the first tightening member 210 is connected to the outer side of the airbag 100; the middle part of the bottom end of the second tightening member 220 is connected to the outer side of the airbag 100.

[0027] In the present embodiment, the airbag 100 is in an annular shape as a whole, and the tightening assembly 200 is arranged on the outside of the airbag 100, and is respectively provided with a first tightening member 210 and three second tightening members 220, and the first tightening member 210 and the second tightening member 220 are all in an arc shape. There is a certain distance between the first tightening member 210 and the second tightening member 220, and between each second tightening member 220. When using the hemostatic ring, the airbag 100 is in a contracted state and can be easily unfolded, and the first tightening member 210 and the second tightening member 220 are separated from each other, ensuring that the hemostatic ring can be easily opened to a sufficient size and put on the part where hemostasis is needed. The second tightening member 220 is detachably connected to the first tightening member 210, and the user can connect the second tightening member 220 and the first tightening member 210 together, or according to the needs, connect each second tightening member 220 and the first tightening member 210 to adapt to the size of the part where hemostasis is needed. The first clamping member 210 is divided into a base 211 and a gas generator 212, the base 211 is connected to the airbag 100, and the gas generator 212 is arranged on the base 211. The base 211 is provided with a one-way air inlet pipe 211a, and the gas generator 212 is provided with an air outlet pipe 212b, and the air outlet pipe 212b cooperates with the one-way air inlet pipe 211a, and the one-way air inlet pipe 211a is connected to the airbag 100, so that gas can be filled into the airbag 100 through the gas generator 212. The bottoms of the second clamping member 220 and the first clamping member 210 are both connected to the outside of the airbag 100, but only the middle part of the bottom is connected to the outside of the airbag 100. When the airbag 100 expands or contracts, the outer area of ​​the airbag 100 will gradually increase or decrease, while the bottom area of ​​the second tightening member 220 and the first tightening member 210 remains unchanged. The setting of connecting only the middle position of the bottom can avoid excessive connection area. When the airbag 100 expands or contracts, the change in the outer area of ​​the airbag 100 may cause tearing at the connection, and it can also ensure that the hemostatic ring has good ductility.

[0028] like Figure 2 , Figure 5 As shown, the clamping assembly 200 is provided with a locking assembly 230, and the locking assembly 230 includes: a first locking piece 231, the first locking piece 231 is arranged on the first clamping piece 210 and the second clamping piece 220; a second locking piece 232, the second locking piece 232 is arranged on the first clamping piece 210 and the second clamping piece 220, and the second locking piece 232 is arranged in the opposite direction to the first locking piece 231, and the second locking piece 232 and the first locking piece 231 cooperate with each other; one end of the first locking piece 231 is provided with a first lock buckle 2311, and one end of the second locking piece 232 is provided with a second lock buckle 2321; the clamping assembly 200 has a locked state and an unlocked state, in the locked state, the first lock buckle 2311 and the second lock buckle 2321 are abutted against each other; in the unlocked state, the first lock buckle 2311 is away from the second lock buckle 2321.

[0029] In the present embodiment, the two ends of the first clamping member 210 and the two ends of each second clamping member 220 are respectively provided with a first locking member 231 and a second locking member 232. The first locking member 231 and the second locking member 232 are arranged relative to each other, and the tops of the first locking member 231 and the second locking member 232 are respectively the first locking buckle 2311 and the second locking buckle 2321, both of which are hook-shaped, and the hooks are oriented in opposite directions, so that they can cooperate with each other and hook together, thereby achieving the effect of locking. The airbag 100 is retractable, so when the first locking buckle 2311 and the second locking buckle 2321 are close, the airbag 100 will not hinder it. When the user puts the hemostatic ring on the part where hemostasis is required, the first locking buckle 2311 and the second locking buckle 2321 are locked according to the demand, so that the clamping assembly 200 becomes a locked state, thereby achieving the fixing effect of the first step and avoiding the dislocation of the hemostatic ring. On the contrary, if the tightening assembly 200 needs to be in an unlocked state, the first lock buckle 2311 can be moved away from the second lock buckle 2321 to make it in an unlocked state.

[0030] like Figure 3 , Figure 4 As shown, the gas generator 212 has an inner cavity, in which a first reaction substance and a second reaction substance are contained, and an isolation layer 212a is provided in the inner cavity, and the isolation layer 212a isolates the first reaction substance and the second reaction substance from each other; the gas generator 212 includes: a connecting portion 2121, the connecting portion 2121 is connected to the base 211; a separating portion 2122, the separating portion 2122 is connected to the connecting portion 2121; wherein the isolation layer 212a is located at the connection between the connecting portion 2121 and the separating portion 2122; the first reaction substance is acetic acid, and the second reaction substance is baking soda.

[0031] In this embodiment, an isolation layer 212a is provided in the gas generator 212 to isolate the first reaction substance and the second reaction substance inside. Preferably, the first reaction substance and the second reaction substance can be selected from acetic acid and baking soda. The isolation layer 212a has a certain upper limit of force. The connecting portion 2121 is connected to the base 211, and the separating portion 2122 is not connected to the base 211. When using the hemostatic ring, after the user fixes the hemostatic ring in position, the user can pry the separating portion 2122, and the isolation layer 212a is at the connection between the separating portion 2122 and the connecting portion 2121. Prying the separating portion 2122 can make the connection active, thereby breaking the isolation layer 212a, so that the first reaction substance and the second reaction substance react to generate gas, thereby achieving the effect of inflating the airbag 100. If the pressure is too high, part of the first locking member 231 and the second locking member 232 can be unlocked to keep them away from each other, so as to achieve the effect of decompression. The airbag 100 is provided with an air outlet hole, and the gas inside the airbag can be released after hemostasis is completed, so that the hemostatic ring can be removed.

[0032] In addition, the gas generator 212 and the base 211 can also be set as a detachable structure, so that the gas generator 212 can be removed from the base 211. Under this setting, after the user fixes the hemostatic ring in place, the gas generator 212 can be removed and shaken with a certain force to break the isolation layer 212a, so that the first reaction substance and the second reaction substance contact each other and react, and then the gas generator 212 is reinstalled on the base 211, and gas is filled into the airbag 100 through the outlet pipe 212b and the one-way inlet pipe 211a to expand it, increase the pressure of the hemostatic ring on the part that needs hemostasis, and then achieve the effect of hemostasis, and if the pressure is insufficient, a new gas generator 212 can be replaced to inflate again until the demand is met.
