Problems solved by technology

[0003] The strength of the above method is insufficient to close, and cannot continuously provide the closing force, the fixation effect is poor, and cannot meet the demand; in the prior art, external fixation devices are also used to achieve the purpose of fixation. In order to make the fixation device fit well with the human body, a The airbag is installed between the fixing device and the human body. Although the airbag can improve the fit and comfort, the shortcoming of the deformation of the airbag also makes it difficult for the small displacement changes of the separated pelvis during transfer or bumping. It is noticed that the instability of the pelvic ring cannot be completely eliminated, and the bleeding control effect is not satisfactory; in addition, the recovery period after the pelvic fracture is long, and it is usually necessary to wear a fixed device for a long time. Decubitus ulcers are prone to occur after long-term contact with the air bag, especially in the protruding part of the pelvic bone
In view of the poor fixation effect of the traditional pelvic fixation device and the defects that decubitus is prone to cause secondary injury and bleeding to the patient, this application proposes a new pelvic fixation device

Embodiment 1

[0037] A kind of pelvic fixation device provided by the present invention comprises:

[0038] The first annular fixing part 1 is fixed around the hip bone and is used to close the hip bones on both sides of the pelvis;

[0039] The second annular fixing part 2 is fixed around the greater trochanter of the femur, and is used to close the greater trochanter of the femur on both sides of the pelvis;

[0040] The circulation fixing mechanism 3 includes four, two of which are respectively arranged on the first ring-shaped fixing member 1, and correspond to the two hip bone wings; the other two are arranged on the second ring-shaped fixing member 2, and are connected to the two There is a one-to-one correspondence between the greater trochanters of the femur; the first ring-shaped fixing part 1 and the second ring-shaped fixing part 2 are provided with installation holes 4 for installing the loop fixing mechanism 3;

[0041] Each circulation fixing mechanism 3 all comprises:

[00...

Embodiment 2

[0047]In order to better fix the first ring-shaped fixing part 1 and the second ring-shaped fixing part 2, on the basis of embodiment 1, this embodiment has two height-adjustable vertical connecting parts 9, and the vertical connecting parts 9 A through groove 10 for passing the first annular fixing part 1 and the second annular fixing part 2 is provided on the top, and the inner and outer surfaces of the vertical connecting part 9 corresponding to the through groove 10 are provided with strips along the width direction of the vertical connecting part 9. shaped notch 11, the strip-shaped notch 11 and the through groove 10 make the vertical connecting member 9 penetrate along the thickness direction;

[0048] A connector 13 is sheathed on the outside of the first limiting member 5, and the first limiting member 5 is set in the strip-shaped gap 11 through the connecting member 13. The outer wall of the connecting member 13 is also provided with upward and downward extending The ...

Embodiment 3

[0052] Such as Figure 4 As shown, in order to make the pressurized part fully contact with the outside air and improve air permeability, a piston cylinder 16 is also provided outside the connecting piece 13, and a piston 17 is arranged inside the piston cylinder 16, and the piston 17 is connected to the first The stopper 5 or the second stopper 6 are connected, and the piston cylinder 16 is provided with an air inlet and an air outlet, and the air inlet is provided with a first one-way valve for allowing external air to enter the piston cylinder 16. Valve, the gas outlet is provided with a second one-way valve for discharging the gas in the piston cylinder 16, and the gas outlet transmits the gas to the first limiter 5 and the second limiter 6 through the air guide tube close to the human body at the end of.

[0053] In this embodiment, on the basis of cyclic pressing, in order to make the pressed skin quickly and effectively contact with the air, on the basis of embodiment ...

Abstract

The invention discloses a pelvis fixing device, and belongs to the technical field of pelvis fixing devices. The pelvis fixing device comprises a first annular fixing piece and a second annular fixingpiece. Two of circulating fixing mechanisms are respectively arranged on the first annular fixing piece and are in one-to-one correspondence with two wings of ilium; the other two are arranged on thesecond annular fixing piece and are in one-to-one correspondence with two greater trochanters of femur; and the first annular fixing piece and the second annular fixing piece are each provided with installation holes used for installing circulating fixing mechanisms. Each circulating fixing mechanism comprises a first limiting part, which is provided with an accommodating cavity and is slidinglyarranged in the installation hole; a second limiting part, which is arranged in the accommodating cavity and is in sliding connection with the accommodating cavity; and a driving mechanism, which is used for driving the first limiting piece and the second limiting piece to reciprocate repeatedly. The pelvis fixing device can provide continuous and stable fixing and folding effects for separated pelvis fractures, bedsores can be well prevented, and the pelvis fixing device is suitable for being worn for a long time.

Description

technical field [0001] The invention relates to the technical field of pelvic fixation devices, in particular to a pelvis fixation device. Background technique [0002] Pelvic fracture is a serious trauma, mostly caused by high-energy trauma, and more than half of them are accompanied by complications or multiple injuries. Due to the huge amount of bleeding in patients with pelvic fractures, patients are prone to hemorrhagic shock and death due to shock. Therefore, for first aid for patients with pelvic fractures, the first thing to do is to close the separated and displaced pelvis after the fracture, and at the same time eliminate or reduce the pain caused by the fracture. Instability of the pelvic ring to achieve the purpose of reducing bleeding. The means for realizing this purpose at present mainly is to use pelvic girdle, abdominal girdle or bed sheet to bind and fix the pelvis. [0003] The strength of the above method is insufficient to close, and cannot continuousl...
