Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an emergency wound fixation device for foreign bodies. Background Technology

[0002] In real life, injuries caused by foreign objects occur frequently due to construction accidents, traffic accidents, natural disasters, and violent conflicts. According to statistics from relevant medical institutions, the number of cases of foreign object injuries caused by accidents is on the rise every year.

[0003] When a foreign object is inserted into the human body, if it is not secured promptly, even slight movement of the object can cause further damage to surrounding tissues, blood vessels, and nerves, increasing the patient's pain and bleeding, and in severe cases, even endangering their life. Currently, traditional fixation methods mainly have the following problems:

[0004] First, the procedure is complex, requiring professional medical personnel to spend a lot of time and energy to fix the foreign object, which is too time-consuming in the critical emergency situation.

[0005] Secondly, the fixation effect is poor, failing to effectively restrict the movement of the foreign object, resulting in insecure fixation. For example, commonly used simple bandaging methods merely wrap around the wound, failing to stably fix the foreign object. Practice shows that after using simple bandaging to fix the foreign object, it often shifts and moves during the transport of the injured person, which greatly increases the patient's pain and risk.

[0006] Third, existing fixing devices often have poor versatility and are difficult to adapt to foreign objects of different shapes, thicknesses and insertion angles. For some irregularly shaped foreign objects, traditional fixing devices cannot fit tightly, thus affecting the fixing effect.

[0007] These problems seriously affect the efficiency of emergency treatment and the success rate of treating the injured. Therefore, how to effectively fix foreign objects at the puncture site is an urgent problem to be solved in this technical field. Summary of the Invention

[0008] The purpose of this invention is to provide a wound fixation device for emergency treatment, thereby improving the aforementioned problems. To achieve this purpose, the technical solution adopted by this invention is as follows:

[0020] Preferably, the rubber clamp is fixedly connected to the hinge plate, and the hinge plate is hinged to the first end of the drive rod.

[0021] Preferably, it also includes a protective mesh cover, with a limiting sleeve at the opening of the protective mesh cover, the limiting sleeve being threadedly connected to the connecting sleeve, and the protective mesh cover being used to protect the wound from foreign objects.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] like Figures 1-3 As shown, this embodiment provides a first-aid wound foreign body fixation device, including:

[0041] The components include a silicone ring 1, an annular housing, an adjusting cylinder 4, and two sets of elastic clamping rods 5, with each set of elastic clamping rods 5 comprising multiple elastic clamping rods 5.

[0042] The annular shell includes a connecting cylinder 2 and a positioning cylinder 3. The positioning cylinder 3 is connected to the connecting cylinder 2 through a connecting plate 31. The connecting cylinder 2 is connected to multiple straps 6.

[0043] The elastic clamping rod 5 is installed through the positioning cylinder 3. The first ends of the two sets of elastic clamping rods 5 are used to abut against the two sides of the foreign object that are not tilted, so as to fix the foreign object.

[0044] The top of the silicone ring 1 is connected to the inside of the connecting tube 2, the bottom of the silicone ring 1 is used to fit against the skin around the puncture site, and the inside of the silicone ring 1 is used to fill medical cotton to stop bleeding.

[0045] The adjusting cylinder 4 is threadedly connected to the connecting cylinder 2. The adjusting cylinder 4 is integrally provided with a driving cone 41, and the inner wall of the driving cone 41 abuts against the tail end of the elastic clamping rod 5.

[0046] Understandably, when securing a foreign object to the puncture site, the silicone ring 1 is placed over the object and slowly and steadily moved downwards until the bottom of the silicone ring 1 is in contact with the skin surrounding the puncture site. Then, the relative position of the silicone ring 1 and the foreign object is slightly adjusted so that the two sets of elastic clamps 5 are positioned on either side of the foreign object without tilting, and the foreign object is located in the middle within the silicone ring 1. Finally, multiple straps 6 are used to secure the silicone ring 1 to the injured person's body. The silicone ring 1, through its contact with the skin surrounding the puncture site and the multiple straps... The binding with 6 restricts the movement of the connecting cylinder 2 and the positioning cylinder 3, forming a stable support structure around the puncture site. Then, the adjusting cylinder 4 is threadedly connected to the connecting cylinder 2. During the threaded connection, the inner wall of the driving cone cylinder 41 abuts against the tail end of the elastic clamping rod 5, simultaneously pushing the heads of the two sets of elastic clamping rods 5 towards the sides where the foreign object is not tilted. After the heads of the two sets of elastic clamping rods 5 abut against the sides where the foreign object is not tilted, the elastic clamping rods 5 retract under the push of the driving cone cylinder 41, and the two sides where the foreign object is not tilted... Applying pressure slowly and steadily allows the two sets of elastic clamps 5 to adapt to the shape of the two sides of the foreign object that are not tilted, providing support on these sides and thus clamping and fixing the foreign object, restricting its movement. Then, through the gap between the silicone ring 1 and the elastic clamps 5, medical cotton is filled into the silicone ring 1 to stop bleeding at the puncture site. The multiple elastic clamps 5 restrict the displacement of the medical cotton, thereby completing the fixation of the foreign object at the puncture site. In this technical solution, the contact between the silicone ring 1 and the skin around the puncture site, along with the binding of multiple straps 6, restricts the movement of the connecting cylinder 2 and the positioning cylinder 3, forming a stable support structure around the puncture site. The driving cone 41 synchronously pushes the tips of the two sets of elastic clamps 5 towards the two sides of the foreign object that are not tilted, reducing time consumption. Under the push of the driving cone 41, the two sets of elastic clamps 5 can adapt to the shape of the two sides of the foreign object that are not tilted, providing support on these sides and clamping and fixing the foreign object, achieving efficient and effective fixation of the foreign object at the puncture site.

[0047] like Figures 3-4 As shown, the top of the positioning cylinder 3 is hinged with two U-shaped clamps 32, which are set with two sets of elastic clamping rods 5. Rubber cards 33 are fixedly connected inside the U-shaped clamps 32. The positioning cylinder 3 is connected to a pressure mechanism 7, which is used to apply a downward deflection force to the two U-shaped clamps 32 so that the two rubber cards 33 can wrap and clamp the foreign object locally to form a second fixed position.

[0048] Understandably, when only a single fixation point is applied to a foreign object, it will still slightly sway during the transport of the injured person, increasing the pain and risk. Therefore, after filling the silicone ring 1 with medical cotton to stop the bleeding at the puncture site, the two U-shaped splints 32 are deflected into the positioning cylinder 3, so that the two rubber clips 33 abut against the two sides of the foreign object that are not tilted. The two U-shaped splints 32 are tilted and placed between the positioning cylinder 3 and the foreign object. Then, the pressure mechanism 7 is connected to the positioning cylinder 3, and the pressure mechanism 7 applies a downward deflection force to the two U-shaped splints 32, causing the two rubber clips 33 to deform between the U-shaped splints 32 and the foreign object. The two rubber clips 33 wrap and clamp the foreign object locally to form a second fixation point. With the help of two sets of elastic clamps 5, the foreign object is fixed in two fixation points, thereby avoiding slight swaying of the foreign object and reducing the pain and risk to the injured person.

[0049] like Figure 5 As shown, the pressurizing mechanism 7 includes a docking cylinder 71, a pressurizing spring 72, and a pressurizing ring plate 73. The docking cylinder 71 is threadedly connected to the positioning cylinder 3. A limiting ring groove 74 is provided in the top of the docking cylinder 71. One end of the pressurizing spring 72 is connected to the limiting ring groove 74. The top of the pressurizing ring plate 73 is rotatably connected to a docking ring plate 75. The docking ring plate 75 is connected to the other end of the pressurizing spring 72. The pressurizing ring plate 73 is located inside the docking cylinder 71. The bottom end of the pressurizing ring plate 73 is used to abut against two U-shaped clamps 32.

[0050] Understandably, after the two U-shaped clamps 32 are tilted and placed between the positioning cylinder 3 and the foreign object, the docking cylinder 71 is threadedly connected to the positioning cylinder 3. During the threaded connection, the pressure ring plate 73 abuts against the two U-shaped clamps 32, and the pressure spring 72 rotates and contracts along with the twisting of the docking cylinder 71. As the pressure spring 72 rotates, it drives the docking ring plate 75 to rotate at the top of the pressure ring plate 73, thereby avoiding vibration of the foreign object caused by friction between the pressure ring plate 73 and the two U-shaped clamps 32. As the pressure spring 72 gradually contracts, the downward deflection force applied by the pressure ring plate 73 to the two U-shaped clamps 32 gradually increases, so that the two rubber clips 33 slowly and steadily wrap and clamp the foreign object locally, avoiding the increase of pain and risk to the injured person.

[0051] like Figures 6-7 As shown, the elastic clamping rod 5 includes a drive rod 51, a docking barrel 52, and a rubber clamping block 53. The drive rod 51 is slidably connected inside the docking barrel 52. The docking barrel 52 is provided through the positioning cylinder 3. A support spring is provided inside the docking barrel 52. The head end of the drive rod 51 abuts against the support spring. An actuating rod 54 is integrally provided at the bottom end of the docking barrel 52. The end of the actuating rod 54 abuts against the inner wall of the drive cone 41. The rubber clamping block 53 is connected to the head end of the drive rod 51.

[0052] Understandably, during the threaded connection between the adjusting cylinder 4 and the connecting cylinder 2, the inner wall of the driving cone 41 abuts against the end of the actuating rod 54. As the driving cone 41 moves downward, the actuating rod 54 pushes the docking barrel 52 to slide within the positioning cylinder 3. The docking barrel 52, through the support spring, pushes the driving rod 51 toward the foreign object, causing the rubber clamp 53 to come into contact with the foreign object. After the rubber clamp 53 comes into contact with the foreign object, the driving rod 51 compresses the support spring and contracts within the docking barrel 52, causing the rubber clamp 53 to slowly and steadily apply pressure on the side of the foreign object that is not tilted, thus avoiding increased pain and risk for the injured person. The foreign object is clamped and fixed by the cooperation of multiple rubber clamps 53.

[0053] like Figure 7 As shown, the trigger rod 54 is provided with a slider 55, the connecting plate 31 is provided with a slide rail 34, the slider 55 is slidably connected to the slide rail 34, the positioning cylinder 3 is provided with a limit channel 35, the limit channel 35 is provided with a limit strip, the outer wall of the docking barrel 52 is provided with a limit groove 56, and the limit strip is slidably connected in the limit groove 56.

[0054] Understandably, the sliding block 55 and the slide rail 34 work together to guide and limit the pushing path of the docking barrel 52. The limiting strip is slidably connected in the limiting groove 56 to further guide and limit the docking barrel 52, so that the docking barrel 52 can stably support and limit the drive rod 51, thereby ensuring the stability of the structural connection and the smoothness of the pushing process.

[0055] It should be noted that the docking barrel 52 is set as a rectangular docking barrel 52, and the drive rod 51 is set as a rectangular drive rod 51. The rectangular drive rod 51 is set in the rectangular docking barrel 52 with clearance fit.

[0056] like Figures 6-7 As shown, a ball bearing 57 is fitted at the end of the actuating rod 54. The ball bearing 57 is used to reduce the friction between the driving cone 41 and the actuating rod 54.

[0057] Understandably, as the cone 41 is driven to move downward by the ball 57 fitted at the end of the actuating rod 54, the ball 57 rubs against the inner wall of the driving cone 41 and rotates inside the end of the actuating rod 54, reducing the friction between the driving cone 41 and the actuating rod 54, reducing the twisting intensity of the threaded connection between the adjusting cylinder 4 and the connecting cylinder 2, and avoiding an increase in the patient's pain and risk.

[0058] like Figure 6 As shown, the rubber clamp 53 is fixedly connected to the hinge plate 58, and the hinge plate 58 is hinged to the first end of the drive rod 51.

[0059] It is understandable that when the cross-section of the foreign object is any of the circular, polygonal, or irregular shapes, the non-inclined side of the foreign object has a slope or arc surface. The rubber clamp 53 can only closely abut against a small part of the slope or arc surface, which limits the supporting and limiting effect of the rubber clamp 53. By fixing the rubber clamp 53 to the hinge plate 58, and the hinged connection between the hinge plate 58 and the first end of the drive rod 51, the rubber clamp 53 can adaptively deflect to the slope or arc surface after it abuts against the non-inclined side of the foreign object. This allows most of the end face of the rubber clamp 53 to abut against the slope or arc surface. After the drive rod 51 applies pressure to the rubber clamp 53 through the hinge plate 58, the rubber clamp 53 then closely abuts against the slope or arc surface of the side of the foreign object, thereby ensuring the supporting and limiting effect of the rubber clamp 53.

[0060] like Figure 1 and Figure 8 As shown, it also includes a protective net cover 8. A limiting cylinder 81 is provided at the opening of the protective net cover 8. The limiting cylinder 81 is threadedly connected to the docking cylinder 71. The protective net cover 8 is used to protect the wound from foreign objects.

[0061] It is understandable that during the transport of the injured person, there is a risk of the foreign object at the puncture site being bumped. Therefore, after the connecting tube 71 and the positioning tube 3 are connected in place by threads, the limiting tube 81 is slowly and steadily placed on the foreign object, and the limiting tube 81 is connected to the connecting tube 71, so that the foreign object is completely inside the protective net cover 8. The protective net cover 8 avoids the risk of the foreign object at the puncture site being bumped. In addition, the protective net cover 8 is lightweight and will not put a great burden on the puncture site. The protective net cover 8 makes it easier for medical staff to observe the foreign object and the bleeding of the injured person.

[0062] like Figure 1 and Figure 9 As shown, a silicone ring 11 is integrally provided at the bottom end of the silicone ring 1, a reinforcing ring 12 is integrally provided between the silicone ring 11 and the silicone ring 1, a plurality of reinforcing ribs 13 are integrally provided on the back side of the silicone ring 11, a plurality of ventilation holes 14 are provided through the silicone ring 11, and the front side of the silicone ring 11 is used to fit against the skin around the puncture site to limit and support the silicone ring 1.

[0063] Understandably, after fine-tuning the relative position of the silicone ring 1 and the foreign object, the front of the silicone ring 11 adheres to the skin around the puncture site. This adhesion further limits the position of the silicone ring 1, making it difficult for it to move. The reinforcing ring 12 strengthens the connection between the silicone ring 1 and the silicone ring 11, reducing deformation at the connection point under tensile force and preventing slight wobbling of the silicone ring 1 at the puncture site. The multiple reinforcing ribs 13 on the back of the silicone ring 11 strengthen its structure, preventing tearing. Multiple ventilation holes 14 ensure breathability, preventing excessive sweating and thus preventing the silicone ring 11 from detaching from the skin.

[0064] As shown in the figure, the back of the silicone ring 11 is integrally provided with multiple protrusions 15, and the protrusions 15 are provided with limiting openings 16, and the strap 6 is inserted into the limiting openings 16.

[0065] Understandably, after multiple straps 6 are tied to the injured person's body, the straps 6 are pressed against and fit inside the limiting port 16. Through the friction between the straps 6 and the limiting port 16, the connecting cylinder 2 cannot make slight wobbling on the silicone ring 1. At the same time, the bottom end of the silicone ring 1 is tightly fitted to the skin around the puncture site. The compression applied by the straps 6 to the protrusion 15 makes multiple points of the silicone ring 11 tightly fitted to the skin around the puncture site, thereby ensuring the connection stability of the silicone ring 11 on the injured person's skin.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
