DETAILED DESCRIPTION

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0046] In the present invention, unless otherwise stated, the directions such as "upper" and "lower" usually refer to the directions shown in the drawings or to the vertical, perpendicular or gravitational directions. Similarly, for the sake of easy understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inner" and "outer" refer to the inner and outer of the contour of each component itself. However, the above orientation terms are not used to limit the present invention.

[0047] For the embodiments, please refer to Figure 1 - Figure 9 , an orthopedic injury care splint, comprising a first connecting plate 1, a splint 2 and a second connecting plate 3, characterized in that: the splint 2 is composed of a plurality of strip plates rotatably connected by hinges, and the first connecting plate 1 and the second connecting plate 3 are respectively rotatably connected to both ends of the splint 2 by hinges;

[0048] A clamping mechanism 4 is arranged on the first connecting plate 1, and a clamping groove 301 matching the clamping mechanism 4 is formed on the second connecting plate 3. After the first connecting plate 1 and the second connecting plate 3 are clamped in a matching manner, the first connecting plate 1, the splint 2 and the second connecting plate 3 are arranged in a circular ring shape;

[0049] A thin film pressure sensor 5 is arranged on one side of the splint 2, and the thin film pressure sensor 5 is arranged inside the circular ring. A honeycomb airbag 6 is arranged on the side of the thin film pressure sensor 5 away from the splint 2, and a breathable layer 7 is detachably installed on the side of the honeycomb airbag 6 away from the thin film pressure sensor 5.

[0050] Currently, after orthopedic doctors set a patient's broken bone, positioning tools are needed to protect and limit the bone to prevent secondary injury to the bone and bone dislocation from affecting the patient's recovery. However, the current positioning tools are generally plaster or disposable polymer splints. Whether it is plaster or disposable polymer splints, for patients with arm bone injuries, it is relatively troublesome to disassemble them during use. And after disassembly, one person cannot tie them back on their own. Even if there is someone else to help, when re-binding the plaster or disposable polymer splint, since the person is neither a professional nor the injured person himself / herself, it is difficult to properly control the tightness of the binding, and the situation of being too loose or too tight may occur, resulting in discomfort for the patient after re-binding.

[0051] Due to problems such as the current positioning tool being inconvenient to disassemble and difficult to re-bind, patients in summer are unable to scrub the skin at the injured position, resulting in problems such as bad smell and skin itching at the wrapped position. Therefore, through the clamping mechanism 4 between the first connecting plate 1 and the second connecting plate 3 in the present invention, the splint 2 can be quickly disassembled and re-bound, enabling regular scrubbing of the injured position of the wrapped part in summer. At the same time, through the setting of the honeycomb airbag 6 and the thin-film pressure sensor 5, it can control the binding force during re-binding. Specifically, after the honeycomb airbag 6 surrounds the arm with the splint 2, by adjusting the clamping position between the first connecting plate 1 and the second connecting plate 3, the inner diameter of the honeycomb airbag 6 is adjusted, so that the inner diameter of the honeycomb airbag 6 fits the wrapped arm. At the same time, the deformation of the honeycomb airbag 6 generates air pressure acting on the thin-film pressure sensor 5, and the binding tightness is controlled through the feedback data of the thin-film pressure sensor 5 to achieve the best binding comfort for the patient.

[0052] Meanwhile, the advantage of being easy to disassemble in the present invention is also that it takes a long time for a patient to be protected and limited in movement by a plaster or a disposable polymer splint on the arm. The arm wrapped with the plaster or the disposable polymer splint is much thicker than a normal arm. The patient has become accustomed to the thicker arm after a long time. When removing the plaster or the polymer splint, the arm muscles that have been wrapped for a long time atrophy, and the arm becomes thinner. Moreover, due to not being cleaned for a long time, it looks rather unsightly. Some people with poor psychological quality may feel nauseous or even faint from fright. In the present invention, the first connecting plate 1 and the second connecting plate 3 are frequently disassembled through the clamping mechanism 4, enabling the patient to frequently scrub the arm during use and visually adapt to the transformation between thick and thin. Therefore, the situation of nausea or fainting will not occur during disassembly.

[0053] Specifically, the first connecting plate 1, the splint 2, and the second connecting plate 3 are made of the same rigid material, such as hard plastic, etc., for the purpose of protecting and limiting the movement of the patient. Among them, the splint 2 is composed of multiple groups of strip plates rotatably connected, and its structure is like a bamboo curtain. After the first connecting plate 1 and the second connecting plate 3 are clamped and matched through the clamping mechanism 4 and the clamping groove 301, they can annularly wrap and fit the patient's arm or leg position and limit the bones on the patient's hand, facilitating bone suture.

[0054] Furthermore, the breathable layer 7 fits the patient's skin. The breathable layer 7 can be made of materials such as cotton cloth and linen. Through its breathable material, when the splint 2 wraps the injured position of the patient, it can have good air permeability, especially in summer.

[0055] It should be noted that the present invention is provided with different models, and the models are differentiated according to the size, that is, the size of the circular ring after the first connecting plate 1 and the second connecting plate 3 are clamped together, so as to adapt to people with different arm thicknesses, and the present invention is a recyclable device. When in use, it can be provided to patients in the form of paying a deposit, and can be returned intact after disassembly at a later time. The breathable layer 7 is a consumable, and the breathable layer 7 and the honeycomb airbag 6 are designed to be detachable. After use by the patient, they can be disassembled and replaced, which is convenient for subsequent hygienic use by the patient. The detachable structure of the breathable layer 7 and the honeycomb airbag 6 includes quick-release structures such as Velcro and buckles.

[0056] Both ends of the first connecting plate 1 close to the film pressure sensor 5 are provided with limit side plates 101, and the limit side plates 101 match with both ends of the second connecting plate 3;

[0057] The limiting side plate 101 and the first connecting plate 1 are integrally formed, the clamping mechanism 4 is arranged at the center of the limiting side plate 101 , and the clamping grooves 301 are opened at both ends of the second connecting plate 3 .

[0058] When the first connecting plate 1 and the second connecting plate 3 are connected, the limiting side plate 101 is provided so that the first connecting plate 1 and the second connecting plate 3 can be slidably fitted and matched, so that the clamping mechanism 4 can quickly correspond to the clamping groove 301 .

[0059] The two sets of side plates 101 are provided with receiving grooves 102 on opposite sides thereof, and a plurality of the receiving grooves 102 are provided in a linear array along the length direction of the side plates 101;

[0060] The clamping mechanism 4 includes a clamping assembly 401 disposed in the plurality of receiving slots 102 , and the clamping assembly 401 and the clamping slots 301 are matched with each other.

[0061] The snap-in slots 301 are arranged in a linear array at both ends of the second connecting plate 3, and the spacing of the linear array of the snap-in slots 301 is smaller than the spacing between the linear arrays of the storage slots 102, so that more snap-in slots 301 are arranged, so that it has a smaller gap adjustment, thereby achieving fine-tuning, and the spacing of the linear array of the storage slots 102 only needs to ensure that the snap-in components 401 can be snapped into the corresponding snap-in slots 301, and the number is greater than 2, because by snapping in at least two snap-in components 401 and the snap-in slots 301, the first connecting plate 1 and the second connecting plate 3 have a better connection effect after being connected. If only one snap-in component 401 is snapped into the snap-in slot 301, then after the first connecting plate 1 and the second connecting plate 3 are connected, the ends will be lifted up, resulting in an unreliable connection between the first connecting plate 1 and the second connecting plate 3.

[0062] The clamping assembly 401 includes a push-out spring 401 a and a clamping block 401 b disposed in the receiving groove 102 . The clamping block 401 b is provided with a sliding arc surface 401 c .

[0063] One end of the push-out spring 401a contacts the inner wall of the storage groove 102, and the other end of the push-out spring 401a contacts one end of the card block 401b. When the first connecting plate 1 is matched and plugged into the second connecting plate 3, the sliding arc surface 401c set on the card block 401b contacts the corner of the second connecting plate 3, so that the card block 401b is retracted into the storage groove 102 and compresses the push-out spring 401a. Then, when the card block 401b moves to the position of the card slot 301, the push-out spring 401a pushes the card block 401b out, so that the card block 401b enters the card slot 301. At this time, the straight side of the card block 401b makes the first connecting plate 1 and the second connecting plate 3 be carded together. An operating cavity 103 communicating with the receiving groove 102 is provided inside the limiting side plate 101, and the operating cavity 103 is arranged above the receiving groove 102. A limiting groove 104 is provided on a side of the operating cavity 103 away from the receiving groove 102, and the limiting groove 104 passes through the first connecting plate 1;

[0064] The clamping mechanism 4 further includes a connecting rod assembly 402 connected to the plurality of clamping assemblies 401, and a driving assembly 403 for moving the connecting rod assembly 402;

[0065] The connecting rod assembly 402 is disposed inside the operating cavity 103 , and the driving assembly 403 and the limiting groove 104 are slidably matched, and the driving assembly 403 and the connecting rod assembly 402 are fixedly connected.

[0066] The driving assembly 403 is used for manual movement by the patient, thereby driving the connecting rod assembly 402 to retract the clamping block 401b into the receiving groove 102, thereby unlocking the clamping connection between the first connecting plate 1 and the second connecting plate 3.

[0067] A connecting column 401d is provided at the top of the block 401b, and the connecting column 401d is rotatably connected to the connecting rod assembly 402;

[0068] The connecting rod assembly 402 includes a sub-connecting rod 402a rotatably connected to the connecting column 401d, and a main connecting rod 402b rotatably connected to an end of the sub-connecting rod 402a away from the connecting column 401d;

[0069] The driving assembly 403 includes a limiting rod 403 a fixedly mounted on the main connecting rod 402 b and a toggle plate 403 b disposed at one end of the limiting rod 403 a away from the main connecting rod 402 b . The limiting rod 403 a is slidably mounted in the limiting groove 104 .

[0070] After the first connecting plate 1 and the second connecting plate 3 are connected, the block 401b is located in the connecting groove 301. When the patient needs to disassemble, the limiting rod 403a is moved in the limiting groove 104 by sliding the toggle plate 403b, thereby driving the main connecting rod 402b to move linearly, thereby causing the multiple sub-connecting rods 402a on the main connecting rod 402b to rotate, thereby dragging the block 401b into the storage groove 102, thereby unlocking the first connecting plate 1 and the second connecting plate 3.

[0071] It should be noted that the main connecting rod 402b and the branch connecting rod 402a are at an acute angle in their initial state, so that the block 401b can be squeezed into the receiving groove 102 normally when the first connecting plate 1 and the second connecting plate 3 are matched and plugged.

[0072] In addition, a sedimentation groove is provided on the first connecting plate 1, and the toggle plate 403b is arranged in the sedimentation groove, and can slide in the sedimentation groove to unlock the block 401b. The setting of the sedimentation groove can prevent the patient from accidentally touching it during binding and use, which may cause the disassembly of the present invention.

[0073] A first magnetic sheet 105 is disposed on a side of the first connecting plate 1 away from the toggle plate 403 b , and a second magnetic sheet 302 is disposed on a side of the second connecting plate 3 away from the film pressure sensor 5 ;

[0074] The first magnetic sheet 105 and the second magnetic sheet 302 are both embedded in each other, and the first magnetic sheet 105 and the second magnetic sheet 302 are magnetically attracted to each other.

[0075] The first connecting plate 1 and the second connecting plate 3 can be preliminarily connected by the first magnetic sheet 105 and the second magnetic sheet 302, that is, when the clamping block 401b is not clamped with the clamping groove 301, the first magnetic sheet 105 and the second magnetic sheet 302 are firstly magnetically attracted to realize the preliminary binding to the patient's arm of the present invention, and then the clamping block 401b and the clamping groove 301 are clamped by the limiting side plate 101 on the first connecting plate 1 and the limiting at both ends of the second connecting plate 3. With the sliding adjustment between the first connecting plate 1 and the second connecting plate 3, the inner diameter of the closed annular ring is reduced, which will cause compression to the honeycomb airbag 6, and then the squeezing force acts on the thin film pressure sensor 5, so that the patient adjusts to a suitable tightness according to the pressure value of the thin film pressure sensor 5. The honeycomb airbag 6 includes an airbag body 601 fixedly mounted on one side of the thin film pressure sensor 5, and also includes a honeycomb diaphragm 602 arranged in the airbag body 601, and a connecting hole 603 opened on the honeycomb diaphragm 602. A breathable membrane 604 is also provided in the airbag body 601 , and a plurality of breathable holes 605 are provided in the airbag body 601 through the breathable membrane 604 .

[0076] The honeycomb airbag 6 and the thin-film pressure sensor 5 are fixed on the splint 2 and the second connecting plate 3. The first connecting plate 1 is used to cover the second connecting plate 3 for snap connection, so that the honeycomb airbag 6 and the thin-film pressure sensor 5 are annularly attached to the patient's arm. 80% of the gas is filled inside the airbag body 601 to support the airbag body 601. And after being bound to the arm, it can better fit the patient's arm through deformation. The setting of the honeycomb diaphragm 602 enables the airbag body 601 to have better strength, so that it can have sufficient limiting and shaping effects on the patient's arm. At the same time, by opening communication holes 603 on the honeycomb diaphragm 602, the internal air flow can circulate, but not quickly, thus avoiding the rapid flow of the gas inside the airbag body 601 due to local movements after binding, thereby affecting its supporting effect.

[0077] Specifically, the gas is evenly divided by the honeycomb diaphragm 602 inside the airbag body 601. Then when there is a local movement and the chambers surrounded by the honeycomb diaphragm 602 are squeezed, the gas inside will flow to other chambers through the communication holes 603, but its flow rate will become less and less. For example, when the stressed chamber is squeezed, the gas will move to the adjacent chamber. However, because the local movement is instantaneous, when the gas flows through the smaller communication holes 603, it will be blocked by the honeycomb diaphragm 602, thereby reducing the gas flow. That is, less gas enters the adjacent chamber, and the gas that enters the adjacent chamber will squeeze the original internal gas and flow to its adjacent chamber. At this time, the gas is blocked by the honeycomb diaphragm 602 again, making the gas flowing out decrease again. Based on the above principle, the gas flow rate is weak, thus ensuring the strength and stability of the honeycomb airbag 6.

[0078] A digital pressure display meter 8 is fixedly installed on the strip plate of the splint 2 close to the second connecting plate 3, and the digital pressure display meter 8 is electrically connected to the thin-film pressure sensor 5.

[0079] The thin-film pressure sensor 5 is composed of multiple pressure sensors connected in series. The multiple pressure sensors are sized to fit on multiple strip plates of the splint 2, so that it can ventilate the breathable layer.

[0080] Furthermore, through the setting of the digital pressure display meter 8, the pressure value of the thin-film pressure sensor 5 is visually displayed, so that when the patient unbinds and then rebinds, they can adjust the binding according to the previous pressure value to ensure the best binding effect.

[0081] Among all the solutions mentioned above, for those involving the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. Whenever fixed connection is involved above, welding is preferably considered. 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.
