Description

A pelvic fixation device to prevent loosening Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pelvic fixation device to prevent loosening. Background Technology

[0002] Pelvic fractures are a common and serious traumatic injury in the emergency department. These injuries, caused by fractures, separation of the pelvic ring, and damage to pelvic organs and blood vessels, lead to significant blood loss and seriously threaten the patient's life. For patients with pelvic fractures, using a pelvic belt in the early post-injury period can minimize fracture displacement, maintain pelvic ring stability, increase pelvic pressure, and reduce organ damage and blood loss.

[0003] However, currently used pelvic belts have a simple structure, only allowing for simple binding like a multi-headed abdominal binder. The pressure they provide is extremely limited; with slight movement, the belt's contractile force may drop to zero, failing to provide continuous and stable pressure and fixation to the injured area. Furthermore, when cleaning anal excrement or observing pressure on the sacrococcygeal skin, the pelvic belt needs to be completely removed, increasing the risk of further pelvic injury when the patient turns over and hindering pelvic stability, thus significantly impacting treatment outcomes. Secondly, current pelvic belts lack versatility; many are of a single size or have difficulty adjusting length, failing to adapt well to the different pelvic shapes of various patients. Thirdly, current pelvic belts offer limited comfort; due to their compressive and fixative properties, prolonged wear may cause skin pressure, abrasion, or allergic reactions.

[0004] There are no effective solutions yet for the problems existing in the related technologies, such as unstable pelvic fixation, easy pressure sores, and inconvenience in length adjustment.

[0171] How to use this utility model:

[0172] In use, the elastic wearable element 11 is first placed on the pelvic ring and covers the upper and lower areas. The first opening element 12 is placed on the patient's sacrum and coccyx. Then, the first locking element 22 and the second locking element 32 are locked together. The length of the first main body element 21 is adjusted by the first adjusting element 24 and the first locking element 22, and the length of the second main body element 31 is adjusted by the second adjusting element 34 and the second locking element 32, thereby fixing the elastic wearable element 11 to the patient's pelvic ring. Then, the connection between the fourth connecting element 62 and the first connecting element 13 is released. The appropriate third adjusting element 41 and fourth adjusting element 51 are selected. The holding element 63 is used to connect the third locking element 61 with the corresponding third adjusting element 41 and fourth adjusting element 51 to adjust the degree of deformation of the elastic wearable element 11, thereby adjusting the pressure of the elastic wearable element 11 on the patient's skin and further fixing the elastic wearable element 11 to the affected area.

[0173] The technical effects of this utility model are as follows:

[0174] Using an elastic wearable unit to fix the patient's pelvic ring and the area above and below it facilitates the cleaning of excrement from the patient's buttocks and the observation of pressure sores. Moreover, it does not require untying the pelvic belt during excretion, which helps to maintain the stability of the patient's pelvis for a long time and solves the problem of unstable pelvic fixation. The tightness of the elastic wearable unit can be adjusted by using the first adjustment unit, the second adjustment unit and the locking unit together, thereby applying pressure to fix the elastic wearable unit. The first connection unit and the second connection unit are used to further fix the elastic wearable unit to the affected area, making the operation simpler and the adjustment more flexible, solving the problem of inconvenient length adjustment.

[0192] Example 3

[0193] This embodiment is a modified embodiment of Embodiments 1 and 2.

[0194] As shown in Figure 9, the pelvic fixation device also includes an airbag unit 70. The airbag unit 70 is disposed in the elastic wearable unit 10 and is used to inflate and deflate to adjust the pressure of the elastic wearable unit 10 on the patient's pelvis.

[0195] As shown in Figure 10, the elastic wearable unit 10 also includes a placement element 17. The placement element 17 is disposed on the side of the elastic wearable unit 10 and is used to place the airbag unit 70.

[0196] The placement element 17 is disposed through the elastic wearable element 11.

[0198] In some of these embodiments, placement element 17 is a placement hole.

[0199] As shown in Figure 11, the airbag unit 70 includes several airbag elements 71, a gas delivery element 72, an air pump element 73, and a switch element 74. The airbag elements 71 are distributed inside the elastic wearable unit 10 and are interconnected, connected to the elastic wearable unit 10, for inflating and deflating to adjust the pressure of the elastic wearable unit 10 on the patient's pelvis, ensuring even pressure. The gas delivery element 72 is located in the elastic wearable unit 10, with its first end connected to the airbag elements 71, for delivering gas to the airbag elements 71. The air pump element 73 is located on the side of the elastic wearable unit 10 and connected to the second end of the gas delivery element 72, for inflating or deflating the gas delivery element 72. The switch element 74 is located on the air pump element 73 and is used to control the inflation or deflation of the air pump element 73.

[0200] Specifically, several airbag elements 71 are located between the elastic wearable element 11 and the cushioning element 15; gas delivery elements 72 are located in the placement element 17; and air pump elements 73 are disposed on the side of the elastic wearable element 11.

[0201] Several airbag elements 71 are arranged in an array.

[0202] The airbag element 71 is connected to the elastic wearable element 11 and the cushioning element 15 in a fixed or detachable manner. The fixed connection method includes, but is not limited to, heat pressing; the detachable connection method includes, but is not limited to, snap-fit.

[0203] The dimensions of the airbag element 71 are matched with the dimensions of the elastic wearable element 11. Generally, the radial dimensions (such as outer diameter, length, and width) of the airbag element 71 are smaller than the radial dimensions (such as length and width) of the elastic wearable element 11.

[0204] In some of these embodiments, the airbag element 71 is an airbag.

[0205] The gas delivery element 72 and the airbag element 71 are connected in a fixed manner. The fixed connection method includes, but is not limited to, integral molding.

[0206] The dimensions of the gas delivery element 72 are matched with the dimensions of the placement element 17. Generally, the radial dimension (e.g., outer diameter) of the gas delivery element 72 is not greater than the radial dimension (e.g., inner diameter) of the placement element 17.

[0207] In some of these embodiments, the gas delivery element 72 is a gas conduit.

[0208] In some of these embodiments, the air pump element 73 is an air pump.

[0209] In some of these embodiments, the switching element 74 is a switch.

[0210] The usage method of this embodiment is as follows:

[0211] After the elastic wearable element 11 is worn on the affected area, the switch element 74 controls the air pump element 73 to inflate the airbag element 71, so that the cushioning element 15 fits the patient's skin more closely and the pressure of the elastic wearable element 11 on the patient's pelvis is more balanced; the air pump element 73 can also be used to deflate the airbag element 71 to adjust the pressure of the airbag element 71 according to the actual situation.

[0212] The technical effects of this embodiment are as follows:

[0213] By incorporating an airbag unit, the pressure of the elastic wearable unit on the patient's skin becomes more even, and the pressure and fixation become more stable. This not only increases the patient's comfort and prevents pressure sores, but also further solves the problem of easy pressure sores.
