TECHNICAL FIELD

[0001] The present application relates to the technical field of limb restraint devices, in particular to a device for pre-hospital emergency lower limb fracture external fixation and carrying. BACKGROUND

[0002] Medical devices refer to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles used directly or indirectly for human beings, including computer software needed.

[0003] At present, the incidence of fractures is gradually increasing due to traffic accidents, the progress of construction industry and the gradual enrichment of people's lifestyle. Many data show that appropriate simple external fixation for patients with lower limb fractures can avoid abnormal movement of fractures during transportation, relieve the pain caused by fractures to patients, and ensure that they do not suffer from secondary injuries. It has a positive effect on anti-shock, reducing mortality and disability rate of patients. The traditional splint has obvious defects, such as easy sliding of the bandage, difficult to control the tightness, large local activity, easy to displace after fixation, excessive pressure, which hinders local blood circulation, aggravates swelling of the distal limb, and produces adverse reactions such as pressure sores and nerve paralysis, affecting the flexibility of use.

[0004] Therefore, there is an urgent need for a device for pre-hospital emergency lower limb fracture external fixation and carrying to solve the above-mentioned problems. SUMMARY

[0005] The purpose of the present application is to provide a device for pre-hospital emergency lower limb fracture external fixation and carrying, which is simple in structure, easy to use, can effectively restrain and fix the limbs of patients, and effectively reduce their resistance to avoid injury.

[0010] In some embodiments of the present invention, the limiting plate is arranged in an arc shape, and the filling pad is arranged at the concave arc of the limiting plate; the thickness of the middle portion of the filling pad is smaller than that of the two ends thereof.

[0011] In some embodiments of the present invention, a support member is provided in the middle of the filling pad, the support member is made of elastic material, and a bandage layer is provided on the outside of the filling pad.

[0012] In some embodiments of the present invention, a groove is provided on the outer side of the limiting plate, a fixing ring is provided in the groove, and the fixing plate is detachably connected with a fixing hook.

[0013] In some embodiments of the present invention, the inflation mechanism includes an inflation device and a pressure measuring tube. A sliding groove is provided in the pressure measuring tube. A pressure plate is slidably connected to the sliding groove. A reset spring is provided on one side of the pressure plate.

[0014] In some embodiments of the present invention, the connecting belt is made of elastic material.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0016] Most existing fixation devices are simple in structure and offer poor comfort, and crude restraints can easily increase patients' irritability and fear. The present invention provides a pre-hospital emergency external fixation and transport device for lower limb fractures, comprising a fixation plate and a fixation assembly. The fixation assembly comprises multiple limiting plates and a connecting belt. The limiting plates are provided with transverse slots, through which the connecting belt passes sequentially. Filling pads are provided on the inner sides of the limiting plates, and the multiple filling pads are connected by a connecting pipe. The filling pads are connected to an inflation mechanism.
