Description

Technical Field

[0001] The present invention relates to the technical field of battlefield first-aid equipment, and specifically to a telescopic splint. Background Art

[0002] In the modern battlefield environment, the time for first-aid treatment of the wounded is crucial for the treatment effect, especially within the critical time window of "Platinum 10 minutes" and "Golden 1 hour". For the fixation and dressing of the wounded, the roll splint is one of the common battlefield first-aid equipment.

[0003] The existing roll splints / plastic splints include the following:

[0004] 1) A roll splint disclosed in the patent publication number CN217489015U;

[0005] 2) A quick-fixing roll splint disclosed in the patent publication number CN216797972U;

[0006] 3) A multifunctional splint for first-aid fixation disclosed in the patent publication number CN221308545U;

[0007] However, the applicability of the above existing roll splints in the battlefield environment still has certain limitations, including the following:

[0008] The relative hardness is insufficient, and it is easy to deform during use or handling: The materials of the existing roll splints are usually relatively soft and lack sufficient support force. It is difficult to provide stable support when handling the wounded or fixing fractures, and it is easy to deform during the process, affecting the first-aid effect.

[0009] The flexibility is not durable enough, and it is easy to break after repeated folding and use: During training, the roll splint needs to be folded and unfolded frequently. Prolonged use will cause the flexibility of the material to decline, and eventually it may break or be damaged, reducing the service life and practicality of the splint.

[0010] The equipment preparation is cumbersome: The existing roll splints require relatively complex preparation work when in use, such as adjusting the length, bending the shape, etc. These steps may waste precious time during the first-aid process, especially in the high-pressure environment of battlefield first-aid, affecting the response speed and efficiency.

[0011] There is uncertainty in the shaping stage, and the fit with the limb is not tight enough: During the use of the splint, how to closely fit the splint with the limb of the wounded is an important issue. The existing roll splints have uncertainty during shaping and cannot well adapt to limbs of different shapes, resulting in unsatisfactory fixation effects, and further affecting the comfort and stability of the wounded.

[0012] Therefore, in a battlefield environment, although existing rollable splints can play a certain role in fixation, they often fail to meet the requirements in emergency situations and under high-intensity use. To effectively improve the effect of battlefield first aid, especially to take rapid and effective first aid measures within a limited time, a new type of splint design that is more stable and easy to operate is urgently needed to address the special challenges of the battlefield environment. Summary of the Invention

[0013] The purpose of the present invention is to provide a telescopic splint. By using the sliding combination of multiple splint modules, it can not only ensure the rapid fixation of the wounded's limb during first aid, but also has better plasticity, stability and operability in use, can more precisely fit different limb shapes, and greatly improves the first aid efficiency.

[0014] To achieve the above purpose, the present invention provides the following technical solution: A telescopic splint, which is at least composed of splint module A, splint module B, splint module C, and splint module D that are slidably connected to each other and limited by a ratchet assembly so that its length can be adapted to the upper limb joint and the lower limb joint. Splint module A, splint module B, splint module C, and splint module D are arranged in sequence along the length direction of the joint. Among them:

[0015] Splint module A is located at the very front end of the entire telescopic splint. Splint module A is arc-shaped and is used for upper limb fixation. The tail end of splint module A is provided with an arc-shaped hook structure for fitting the elbow or ankle. The design of the arc-shaped hook structure reduces the complexity of the traditional splint during use. First aid personnel can achieve precise fixation of the elbow or ankle without additional adjustment operations, and first aid personnel can quickly and easily fix the wounded, thus greatly improving the first aid efficiency. Especially in a battlefield environment, the outside of splint module A is provided with a first sliding strip that protrudes outward;

[0016] Splint module B is located between splint module A and splint module C. Splint module B and splint module C have the same structure. Grooves and second sliding strips are respectively arranged on the inner and outer sides of the main body tops of splint module B and splint module C. Among them, the groove includes a communicating receiving groove and a first sliding groove. The first sliding groove is located at the rear end of the receiving groove. The shape of the first sliding groove matches the first sliding strip on the outside of splint module A. Splint module B and splint module C are slidably connected and matched through the first sliding groove and the second sliding strip;

[0017] Splint module D is located at the tail end of the entire telescopic splint. The inside of splint module D is provided with a receiving groove and a second sliding groove that matches the second sliding strip on splint module C.

[0018] Preferably, notches are provided at the ends of the first sliding strip and the second sliding strip.

[0019] Preferably, the ratchet assembly includes a long rack, a gear, a ratchet, an elastic column and a button. The long rack is distributed in the notches of the first slide and the second slide on the splint module A, the splint module B and the splint module C. The gear is rotatably installed in the receiving groove and meshes with the long rack. The ratchet is coaxially connected to the gear.

[0020] Preferably, a button is provided at the upper end of the elastic column, and a limiting ratchet tooth cooperating with the ratchet is provided at the lower end of the elastic column. The limiting ratchet tooth descends when the button is pressed and separates from the ratchet to unlock the sliding state between the splint module A, the splint module B, the splint module C and the splint module D.

[0021] Preferably, the splint module A, the splint module B, the splint module C and the splint module D are made of glass fiber reinforced polypropylene material. The glass fiber reinforced polypropylene (GF-PP) material has high strength and rigidity, and is more impact-resistant and deformation-resistant than ordinary polypropylene materials. This enables the splint to provide stronger support under stress, preventing deformation or fracture during first aid and ensuring that the splint can stably support the injured limb for a long time in the battlefield or emergency situations. In addition, the polypropylene material itself has a low density, so the splint made of GF-PP material is lighter than traditional metal or other material splints, making it convenient for first aid personnel to carry and operate. In complex environments such as the battlefield, a light and easy-to-carry splint can ensure that first aid personnel do not increase their burden when performing tasks and can quickly and flexibly fix the wounded.

[0022] Preferably, a breathable inner lining is attached to the inner sides of the splint module A, the splint module B, the splint module C and the splint module D. The breathable inner lining is a medical-grade skin-friendly silicone pad that conforms to the limb curve. The medical-grade skin-friendly silicone has extremely high skin-friendliness and can be in close contact with the skin without causing allergies or discomfort. The silicone material is soft and elastic, can perfectly conform to the curve of the human limb, provides soft support and a comfortable touch. In addition, when used for a long time, it can effectively disperse pressure, reduce local compression, and avoid pressure sores caused by the long-term compression of the skin by the splint, especially when the splint is worn for a long time.

[0023] Preferably, strap grooves are preset on both sides of the inner sides of the splint module A, the splint module B, the splint module C and the splint module D. The restraint strap passes through the strap grooves, and the end of the restraint strap is fixed by a magic tape. The restraint strap passes through the strap grooves, and the end of the strap is fixed by a magic tape. This design gives the splint a more efficient and simple operation method, can quickly complete the fixation within 30 seconds, realizes tightening with one pull, and enables the splint to complete the fixation in an extremely short time.

[0024] Preferably, a number of ventilation openings are distributed on the splint modules A, B, C, and D. The ventilation openings can cooperate with the breathable inner lining to avoid skin stuffiness. In addition, the material of the splint module can also be set as polycarbonate (PC) or polyethylene (PE), etc., to meet the X-ray penetration and allow X-ray examination without removing the splint. In the traditional first aid scenario, the injured person needs to remove the splint first and then undergo X-ray examination, which not only wastes time but may also cause the splint to not return to its original state, affecting subsequent treatment. After using the splint designed by the present invention, the first aid personnel can quickly complete the fixation and perform imaging examination without removing the splint.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The splint of the present invention can not only ensure the rapid fixation of the injured person's limb during first aid, but also has better plasticity, stability, and operability during use, can fit different limb shapes more precisely, and greatly improves the first aid efficiency.

[0027] The specific technical effects are as follows:

[0028] 1. The telescopic splint of the present invention adopts a four-section sliding structure, and the splint can quickly adapt to the needs of different injured parts. The first aid personnel can complete the adjustment and fixation of the splint in just 20 seconds, which greatly shortens the operation time of the traditional splint and improves the first aid efficiency. Compared with the traditional roll-type splint, the splint of the present invention reduces the first aid time to 1 / 6 of the time required by the traditional splint, providing strong support for rapid rescue in the battlefield environment. In addition, through the telescopic design, the splint of the present invention can flexibly adjust the length and width, enabling it to effectively fix various limb injuries. This design ensures that the splint can accurately fit various parts of the human body (such as the upper limb and the lower limb) to provide the best fixation effect. Whether it is the arm, leg, or ankle, the splint can quickly adapt through adjustment to meet the first aid needs of different injured persons.

[0029] 2. The present invention adopts a modular design and combines automatic locking and adjustment functions, making the use process of the splint simpler and faster. The first aid personnel can accurately adjust according to the limb condition of the injured person in a short time. It is not only applicable to the first aid fixation of the upper limb and the lower limb, but also can meet the fixation needs of different parts through adjustment design. In addition, the combination of the ratchet assembly and the fixing belt can firmly fix the limb of the injured person, prevent the splint from loosening or shifting during movement, and ensure stable support for the injured person in case of emergency.

[0030] 3. The inner side of the splint of the present invention is designed with a breathable lining, which uses a medical-grade skin-friendly silicone pad material to provide high comfort and breathability, effectively reducing the risk of skin pressure sores. Multiple ventilation holes are also provided on the surface of the splint to avoid discomfort such as airtightness and stuffiness during long-term wearing, improving the wearing experience of patients. At the same time, the splint adopts a lightweight design. While maintaining strength and functionality, the splint has good portability. Emergency personnel can easily carry it and quickly take it out for use in case of emergency, which is especially suitable for first aid needs in environments such as the battlefield.

[0049] In this embodiment, a number of breathable openings (opening rate ≥ 40%) are distributed on the splint modules A1, B2, C3, and D4. The breathable openings can cooperate with the breathable lining to prevent the skin from feeling stuffy.

[0050] In Embodiment 1 of the present invention, the splint modules A1, B2, C3, and D4 are designed as splint components with telescopic functions, capable of effectively fixing the limbs of the wounded according to different injuries, and are particularly suitable for first aid scenarios such as upper limbs, lower limbs, and femoral fractures.

[0051] Practical Application 1: When the wounded has an upper limb fracture, the splint module A1 can be quickly deployed and, through telescopic limit, adapt to the shape of the wounded's upper limb to achieve a fixation effect.

[0052] Practical Application 2: When the wounded has a lower limb fracture, the splint module A1 and the splint module C3 cooperate through a slide bar and can be quickly deployed and adapted to the lower limb of the wounded. In this way, the lower limb of the wounded can be accurately fixed without displacement.

[0053] Practical Application 3: When dealing with femoral fractures, all four splint modules are deployed and limited by an adjustable ratchet 11 assembly, so that the splint can be tightly fixed to the thigh of the wounded.

[0054] In addition, this embodiment also provides the control steps for the telescopic limit between the above-mentioned splint modules A1, B2, C3, and D4, which are as follows: The operator presses the button 14 and makes the limit ratchet 13 move downward and separate from the ratchet 11. At this time, the sliding state of the current two splint modules is unlocked. The operator adjusts the telescopic length between the two splint modules according to needs. After adjustment, release the button 14, and the limit ratchet 13 moves upward under the action of elastic force and limits the ratchet 11. At this time, the current two splint modules are in a limited state.

[0055] Embodiment 2: In this embodiment, the splint modules A1, B2, C3, and D4 are made of glass fiber reinforced polypropylene material. The glass fiber reinforced polypropylene (GF-PP) material has high strength and rigidity, and is more impact-resistant and anti-deformation than ordinary polypropylene materials. This enables the splint to provide stronger support force under stress, preventing deformation or fracture during first aid, and ensuring that the splint can stably support the injured limb for a long time in the battlefield or emergency situations. In addition, the polypropylene material itself has a low density. Therefore, the splint made of GF-PP material is lighter than traditional metal or other material splints, which is convenient for first aid personnel to carry and operate. In complex environments such as the battlefield, a light and easy-to-carry splint can ensure that first aid personnel do not increase the burden when performing tasks and can quickly and flexibly fix the wounded.

[0056] Embodiment 3: In this embodiment, the materials of splint module A1, splint module B2, splint module C3, and splint module D4 can also be set as polycarbonate (PC), polyethylene (PE), etc., to meet the X-ray penetration and allow radiography without removing the splint. In traditional first-aid scenarios, the injured need to first remove the splint and then undergo X-ray examination, which not only wastes time but may also cause the splint to not return to its original state, affecting subsequent treatment. After using the splint designed by the present invention, first-aid personnel can quickly complete fixation and perform imaging examination without removing the splint.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
