Description

TECHNICAL FIELD

[0002] In real life, due to construction accidents, traffic accidents, natural disasters and violent conflicts, the human body is often injured by foreign objects. According to the statistical data of relevant medical institutions, the number of cases of foreign object injury caused by accidents is increasing year by year.

[0003] When a foreign object is inserted into the human body, if it is not fixed in time, the slight shaking of the foreign object can cause further damage to the surrounding tissues, blood vessels and nerves, increase the pain and bleeding of the injured person, and even endanger life in severe cases. At present, the traditional fixing method mainly has the following problems: First, the operation is complex, and professional medical personnel need to spend a lot of time and effort to fix the foreign object, which is too high in time cost in the first-aid scene where every second counts; Second, the fixing effect is not good, and it cannot effectively limit the movement of the foreign object, resulting in unstable fixation. For example, the commonly used simple bandaging method only simply wraps around the wound, and cannot stably fix the foreign object.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative work based on the embodiments in the present application belong to the scope of protection of the present application.

[0020] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0021] As shown in Figures 1-3 the embodiment provides a wound foreign body fixator for first aid, which comprises: The silicone ring 1, the annular shell, the adjusting barrel 4 and the two groups of elastic clamping rods 5, each group of elastic clamping rods 5 comprises a plurality of elastic clamping rods 5; The annular shell comprises the connecting barrel 2 and the positioning barrel 3, the positioning barrel 3 is connected in the connecting barrel 2 through the connecting plate 31, and the connecting barrel 2 is connected with a plurality of bandages 6; The elastic clamping rod 5 is arranged through the positioning barrel 3, and the first ends of the two groups of elastic clamping rods 5 are used for abutting against two sides of the foreign body which are not inclined, so as to fix the foreign body; The top of the silicone ring 1 is connected in the connecting barrel 2, the bottom end of the silicone ring 1 is used for being attached to the skin around the wounded part, and the silicone ring 1 is used for filling medical cotton hemostatic; The adjusting cylinder 4 is threadedly connected with the connecting cylinder 2, and the driving cone cylinder 41 is integrally arranged on the adjusting cylinder 4, and the inner wall of the driving cone cylinder 41 abuts against the tail end of the elastic clamping rod 5.

[0022] It can be understood that when the foreign matter at the puncture site is fixed, the silica gel ring 1 is sleeved on the foreign matter, slowly and smoothly moved downward until the bottom end of the silica gel ring 1 is used to be in close contact with the skin around the puncture site, and then the relative position of the silica gel ring 1 and the foreign matter is adjusted, so that the two groups of elastic clamping rods 5 are located on the two sides of the foreign matter which are not inclined, and the foreign matter is located in the middle position in the silica gel ring 1, and then the silica gel ring 1 is bound on the body of the wounded person through the plurality of bandages 6, the silica gel ring 1 is limited to the active position of the connecting cylinder 2 and the positioning cylinder 3 through the close contact with the skin around the puncture site and the binding of the plurality of bandages 6, a stable support structure is formed around the puncture site, then the adjusting cylinder 4 is threadedly connected with the connecting cylinder 2, in the process of threadedly connecting, the inner wall of the driving cone cylinder 41 abuts against the tail end of the elastic clamping rod 5, and the head ends of the two groups of elastic clamping rods 5 are synchronously pushed to the two sides of the foreign matter which are not inclined, after the head ends of the two groups of elastic clamping rods 5 abut against the two sides of the foreign matter which are not inclined, the elastic clamping rod 5 is contracted under the pushing of the driving cone cylinder 41, and slowly and smoothly exerts pressure on the two sides of the foreign matter which are not inclined, so that the two groups of elastic clamping rods 5 can adapt to the shape of the two sides of the foreign matter which are not inclined and support the two sides of the foreign matter which are not inclined, thereby clamping and fixing the foreign matter and limiting the movement of the foreign matter, then medical cotton is filled in the silica gel ring 1 through the gap between the silica gel ring 1 and the elastic clamping rod 5 to stop bleeding at the puncture site, and the plurality of elastic clamping rods 5 can limit the displacement of the medical cotton, thereby completing the fixation of the foreign matter at the puncture site; in this technical solution, the silica gel ring 1 is limited to the active position of the connecting cylinder 2 and the positioning cylinder 3 through the close contact with the skin around the puncture site and the binding of the plurality of bandages 6, a stable support structure is formed around the puncture site, the head ends of the two groups of elastic clamping rods 5 are synchronously pushed to the two sides of the foreign matter which are not inclined by the driving cone cylinder 41, time consumption is reduced, the two groups of elastic clamping rods 5 can adapt to the shape of the two sides of the foreign matter which are not inclined and support the two sides of the foreign matter which are not inclined under the pushing of the driving cone cylinder 41, thereby clamping and fixing the foreign matter, and efficient fixation of the foreign matter at the puncture site is realized.

[0023] As shown in Figures 3-4 The top end of the positioning cylinder 3 is hinged with two U-shaped clamping plates 32, the two U-shaped clamping plates 32 are arranged corresponding to the two groups of elastic clamping rods 5, the U-shaped clamping plate 32 is fixedly connected with a rubber card 33, the positioning cylinder 3 is connected with a pressing mechanism 7, the pressing mechanism 7 is used to apply a downward deflection force to the two U-shaped clamping plates 32, so that the two rubber cards 33 wrap and clamp the local part of the foreign matter to form a second fixed position.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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 installed 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.

[0028] It can be understood that in the process of adjusting the cylinder 4 and the connecting cylinder 2 are threadedly connected, the inner wall of the driving cone cylinder 41 abuts against the end of the triggering rod 54, the driving cone cylinder 41 moves downward, the butt joint barrel 52 is pushed to slide in the positioning cylinder 3 by the triggering rod 54, the butt joint barrel 52 pushes the driving rod 51 to approach the foreign matter by the support spring, so that the rubber clamp block 53 abuts against the foreign matter, after the rubber clamp block 53 abuts against the foreign matter, the driving rod 51 extrudes the support spring to shrink in the butt joint barrel 52, so that the rubber clamp block 53 slowly and stably applies pressure on the side of the foreign matter that is not inclined, avoiding the increase of the pain and risk of the injured person, and the foreign matter is clamped and fixed by the cooperation of the plurality of rubber clamp blocks 53.

[0029] As shown in Figure 7 , the triggering rod 54 is provided with a sliding block 55, the connecting plate 31 is provided with a sliding rail 34, the sliding block 55 and the sliding rail 34 are in sliding connection, a limiting channel 35 is throughly arranged in the positioning cylinder 3, a limiting strip is arranged in the limiting channel 35, and the outer wall of the butt joint barrel 52 is provided with a limiting groove 56, and the limiting strip is in sliding connection in the limiting groove 56.

[0030] It can be understood that the pushing path of the butt joint barrel 52 is guided and limited by the cooperation of the sliding block 55 and the sliding rail 34, the limiting strip is in sliding connection in the limiting groove 56, and the butt joint barrel 52 is further guided and limited, so as to stably support and limit the driving rod 51, thereby guaranteeing the stability of the structure connection and the stability of the pushing process.

[0031] It should be noted that the butt joint barrel 52 is arranged as a rectangular butt joint barrel 52, and the driving rod 51 is arranged as a rectangular driving rod 51, and the rectangular driving rod 51 is arranged in clearance fit in the rectangular butt joint barrel 52.

[0032] As shown in Figures 6-7 , the end of the triggering rod 54 is embedded with a ball 57, and the ball 57 is used to reduce the friction between the driving cone cylinder 41 and the triggering rod 54.

[0033] It can be understood that the ball 57 embedded at the end of the triggering rod 54, when the driving cone cylinder 41 moves downward, the ball 57 rotates in the end of the triggering rod 54 after friction with the inner wall of the driving cone cylinder 41, thereby reducing the friction between the driving cone cylinder 41 and the triggering rod 54, reducing the twisting intensity of the adjusting cylinder 4 and the connecting cylinder 2, and avoiding the increase of the pain and risk of the injured person.

[0034] As shown in Figure 6 , the rubber clamp block 53 is fixedly connected to the hinged plate 58, and the hinged plate 58 is hinged to the first end of the driving rod 51.

[0035] It can be understood that when the cross section of the foreign matter is any one of a circle, a polygon, or an irregular shape, the non-inclined side of the foreign matter has a slope or an arc surface, and the rubber clamp block 53 can only tightly abut against a small part of the slope or the arc surface, so that the supporting and limiting effect of the rubber clamp block 53 is limited. By fixedly connecting the rubber clamp block 53 to the hinged plate 58 and hingedly connecting the hinged plate 58 to the first end of the driving rod 51, after the rubber clamp block 53 abuts against the non-inclined side of the foreign matter, the rubber clamp block 53 can be deflected to adapt to the slope or the arc surface, so that most of the end surface of the rubber clamp block 53 can abut against the slope or the arc surface. After the driving rod 51 exerts pressure on the rubber clamp block 53 through the hinged plate 58, the rubber clamp block 53 tightly abuts against the slope or the arc surface of the side of the foreign matter, thereby guaranteeing the supporting and limiting effect of the rubber clamp block 53.

[0036] As shown in Figure 1 and Figure 8 , the protective mesh cover 8 is provided with a limiting cylinder 81 at the cover opening, the limiting cylinder 81 is threadedly connected to the butt joint cylinder 71, and the protective mesh cover 8 is used to protect the foreign matter at the wound.

[0037] It can be understood that during the process of transporting the injured person, the foreign matter at the wounded part has a risk of being collided, so after the butt joint cylinder 71 is threadedly connected to the positioning cylinder 3 in place, the limiting cylinder 81 is slowly and smoothly sleeved on the foreign matter, and the limiting cylinder 81 is connected to the butt joint cylinder 71, so that the whole foreign matter is located in the protective mesh cover 8, thereby avoiding the risk of the foreign matter at the wounded part being collided through the protective mesh cover 8, and the protective mesh cover 8 is relatively light and does not increase a large burden on the wounded part, so that the medical staff can easily observe the foreign matter and the bleeding condition of the injured person through the protective mesh cover 8.

[0038] As shown in Figure 1 and Figure 9 , the bottom end of the silica gel ring 1 is integrally provided with a silica gel ring sheet 11, a reinforcing ring 12 is integrally arranged between the silica gel ring sheet 11 and the silica gel ring 1, the back surface of the silica gel ring sheet 11 is integrally provided with a plurality of reinforcing ribs 13, and a plurality of air holes 14 are arranged through the silica gel ring sheet 11. The front surface of the silica gel ring sheet 11 is used to be attached to the skin around the wounded part, so as to limit and support the silica gel ring 1.

[0039] It can be understood that after fine-tuning the relative position of the silica gel ring 1 and the foreign matter, the front surface of the silica gel ring sheet 11 is attached to the skin around the puncture site, and the position of the silica gel ring 1 is further limited by the attachment of the silica gel ring sheet 11 to the skin, so that the silica gel ring 1 is difficult to move. The connection of the silica gel ring 1 and the silica gel ring sheet 11 is strengthened by the reinforcing ring 12, which slows down the deformation of the connection between the silica gel ring 1 and the silica gel ring sheet 11 under the pulling force, avoids the slight shaking of the silica gel ring 1 at the puncture site, and the multiple reinforcing ribs 13 provided on the back surface of the silica gel ring sheet 11 strengthen the structure of the silica gel ring sheet 11 to avoid tearing of the silica gel ring sheet 11. The multiple air holes 14 ensure air permeability to prevent the patient's skin from sweating and causing the silica gel ring sheet 11 to detach from the skin.

[0040] As shown in the drawings, the back surface of the silica gel ring sheet 11 is integrally provided with multiple bosses 15, and the bosses 15 are provided with limiting openings 16.

[0041] It can be understood that after the multiple straps 6 are bound to the patient's body, the straps 6 are attached to the limiting openings 16, and the connection cylinder 2 cannot move slightly on the silica gel ring 1 by the friction between the straps 6 and the limiting openings 16. At the same time, the bottom end of the silica gel ring 1 is tightly attached to the skin around the puncture site, and the multiple points of the silica gel ring sheet 11 are tightly attached to the skin around the puncture site by the extrusion of the straps 6 to the bosses 15, thereby ensuring the connection stability of the silica gel ring sheet 11 on the patient's skin.

[0042] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0043] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which shall be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
