Description
Technical Field
The utility model belongs to the technical field of medical appliances technique and specifically relates to a novel automatic inflation cervical vertebra external fixation ware.
Background
When the head and the cervical vertebra of a patient are not injured in a rescue scene, the head and the neck of the patient are not required to be moved randomly, the patient in emergency is carried by using a stretcher generally, however, the stretcher used in emergency is not provided with an automatic inflatable cervical vertebra fixing support and the like. Most of the external cervical vertebra fixators used in clinical or rescue situations are split and inconvenient to store. When the external cervical vertebra fixing device is worn by a patient in emergency rescue, the patient mostly needs to be turned over, at least two persons are needed to cooperate to turn over in order to protect the stability of the whole spine, particularly the cervical vertebra of the patient, and secondary injury is easily caused to the patient carelessly in the process of turning over and moving the patient, so that the patient is aggravated, and the patient is paralyzed by a serious patient. In addition, the stretcher or the ambulance cot used in the transportation process and the required external cervical vertebra fixator are separately placed, and cannot be integrated, so that the medical staff can conveniently carry out the equipment.
In addition, most of the currently used external cervical vertebra fixators cannot be matched with a stretcher for use, and meanwhile, the opening and inflation time of the fixator is slow, the carrying is inconvenient, and the speed and time of first aid are often influenced.
Chinese patent documents: CN203107464U, published: 2013.08.07 discloses a stretcher with automatic inflatable cervical vertebra fixing support, including stretcher frame, stretcher face, the both ends of stretcher frame are equipped with the handle respectively, and the well front portion of stretcher face is fixed with automatic inflatable cervical vertebra fixing support, and inflatable cervical vertebra fixing support is including U type gasbag, and there is defeated balloon at the air inlet of U type gasbag through intake-tube connection, is equipped with the valve in the intake pipe. Has the advantages that: the inflatable pillow can be inflated or deflated by using the air conveying balloon according to the needs of the patient, the bottom of the U-shaped air bag is fully contacted with the neck of the patient and the stretcher surface, the neck of the patient is effectively fixed and prevented from moving, and the comfort level of the patient is increased. But the speed is slow when the inflatable pillow is inflated by the technical scheme, so that first aid is not facilitated; in addition, the inflatable pillow in the technical scheme is matched with a specific stretcher in the technical scheme for use, and is not suitable for popularization.
Chinese patent documents: CN201394104, published date: 2010.02.03, discloses an automatic inflatable cervical vertebra tractor with massage function; the air bag inflator comprises an air bag and an inflator pump which are connected through an air guide tube, a fixed valve body sleeved on a rotating shaft of a synchronous motor is arranged between the air guide tube and the inflator pump, an air inlet hole communicated with the inflator pump through an air inlet tube and at least one air outlet tube communicated with the air guide tube are arranged on the fixed valve body, an air outlet hole is formed in the air outlet tube, a movable valve body matched with the fixed valve body is fixed on the rotating shaft of the synchronous motor, an air inlet channel matched with the air inlet hole, an air outlet through hole and an air outlet channel matched with the air outlet hole are arranged on the movable valve. Has the advantages that: the air bag circularly swells and collapses, so as to massage the neck of the human body, thereby being beneficial to the treatment; the synchronous motor is provided with a timing device, and the air flushing and discharging process can be controlled according to needs. However, the technical scheme mainly massages and pulls the cervical vertebra, does not relate to external fixation of the cervical vertebra, is slow in inflating speed, is not suitable for emergency treatment, and cannot be used together with a stretcher; the device is complicated in structure and not easy to carry and operate.
In summary, there is a need for a novel automatic-inflating external cervical vertebra fixator which can fix a fixing air bag on a stretcher, can rapidly and automatically inflate the fixing air bag, can be folded and stored, has a physical traction effect on the neck, and effectively maintains the physiological curvature of the cervical vertebra, and no relevant report is found at present.
