Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model discloses a first gasbag 1, manometer 2, second gasbag 3, trachea 4, magic subsides son face 5, connecting band 6, magic subsides mother face 7, fixed plate 8 and pneumatic valve 9 part are the parts that universal standard spare or field technician know, and its structure and principle all can learn through the technical manual or learn through conventional experimental method for this technical staff.

Referring to fig. 1-3, an inflatable metacarpal fracture fixator comprises a first air bag 1, wherein the lower end of the right side of the first air bag 1 is communicated with the middle end of the left side of a second air bag 3 through an air pipe 4, a pressure gauge 2 is fixedly installed at the left end of the air pipe 4, the second air bag 3 is in an elastic round ball shape and is filled with nitrogen, an air valve 9 is fixedly installed at the right end of the air pipe 4, and a fixing plate 8 is fixedly connected to the lower end of the inner surface of the first air bag 1, when people fix the metacarpal bones through the inflatable metacarpal fracture fixator, people firstly sleeve the first air bag 1 on injured hands, then are connected with a magic tape surface 5 on a connecting belt 6 and a magic tape female surface 7 in a thread gluing manner, so that the first air bag 1 is not easy to slide off from the hands, then press the second air bag 3 with the hands while opening the air valve 9, the nitrogen in the second, first gasbag 1 can expand, extrusion fixed plate 8, fixed plate 8 is fixed the metacarpal bone, manometer 2 can detect the atmospheric pressure in the first gasbag, avoid the too big blood vessel of oppression of pressure, blood does not circulate, pressure then can not play fixed treatment effect that resets for a short time, when atmospheric pressure reaches the set pressure value, close pneumatic valve 9, then first gasbag 1 and second gasbag 3 do not communicate, thereby reached the mesh that facilitates the use, the bottom fixedly connected with connecting band 6 of

first gasbag

1, 6 positive left ends of connecting band have magic subsides female face 7 through the viscose connection, the right-hand member at the 6 backs of connecting band is connected with magic subsides son face 5 through the viscose, first gasbag 1 is for not pointing the gloves shape.

When the inflatable metacarpal fracture fixator is used, the first air bag 1, the second air bag 3, the air pipe 4, the fixing plate 8 and the air valve 9 are arranged, when people fix metacarpals by the inflatable metacarpal fracture fixator, people firstly sleeve the first air bag 1 on an injured hand, then the first air bag 1 is in thread gluing connection with the magic female surface 7 through the magic male surface 5 on the connecting belt 6, so that the first air bag 1 is not easy to slide off the hand, then the second air bag 3 is extruded by the hand while the air valve 9 is opened, nitrogen in the second air bag 3 enters the first air bag 1 through the air pipe 4, the first air bag 1 expands, the fixing plate 8 is extruded, the fixing plate 8 fixes the metacarpals, the pressure gauge 2 can detect the air pressure in the first air bag 1, the phenomenon that the blood vessel is pressed due to overlarge pressure, blood does not circulate, the fixing and the treatment effect of resetting cannot be realized due to small pressure is avoided, when the air pressure reaches a set pressure, the first air bag 1 and the second air bag 3 are not communicated, so that the purpose of convenient use is achieved, and the problems that the existing inflatable fracture fixator is inconvenient to use, heavy, cumbersome to use and difficult for the wounded to save oneself are solved.
