Capsule field first-aid device for bone

Abstract To introduce first-aid device capsule production field theory bone structure, and clinical use of methods and precautions. Methods capsule airbags as the main fixed component, built-in filter wrapped by the plastic polymer particles as a filler material with suction devices, embedded in the improved first aid stretcher. Results According to the Chinese Medical Association Orthopaedic Traumatology credit evaluation standards will: excellent in 28 cases, good in 6 cases, 1 case, good rate of 97%. Conclusion This device is suitable for field first aid, which are portable, fixed operating time is short, fixed effect, can effectively prevent the removal process of secondary injury to the patient characteristics. The device is suitable for a variety of fractures and dislocation of the fixed-site first aid, ambulance fractures to solve the traditional materials (apparatus) of the limitations and shortcomings, and has good clinical application.

Abstract: Objective To Introduce the principles and the structures of a field aerocyst device for first  aid of bone injury, as well as its operative method and precaution. Methods The aerocyst was used as the main fixing component, built in the plastic polymer particles with filter packages as the filler material, accompanied with air extractor devices, and embedded in improved strecher for first aid.Results According to the evaluation criteria of bone injury fixatiion from Chinese Medical Association Orthopedics Branch, the outcomes were listed as follow: excellent in 28, good in 6, and fair in 1 case (s). The total fine (excellent + good) rate was 97%. Conclusion It is suggested that the device is applicable to many bone injuries especially to spine compression fractures for on  site first aid. It is easy to be carried, and takes less time to operate. It solves the problem of the limitation and deficiency of the traditional materials. It has a good practice value.

Fracture dislocation of the fixed material the use of traditional fixed, and in some parts and can not play a fixed role, especially for patients with spine fractures and even cause secondary damage [1]. Ping wartime military rescue mission and a variety of medical first aid trauma timeliness of war,[link widoczny dla zalogowanych], evacuation of the trauma material (equipment) launched the efficiency and effectiveness of treatment put forward higher requirements. To this end, we started in 2006 and first-aid pouch-type field device for bone, by 2 years probation and improvement. December 2006 to March 2008, respectively, in 35 cases of traumatic fracture, joint dislocation were used in the field of fixed capsule carrying aid bone field devices, to achieve a satisfactory clinical results.
1 capsule field first-aid device for bone
1.1 Capsule First Aid Device for bone field theory when the balloon pressure with the outside world under the same atmospheric pressure, the soft capsule filling, shape, plastic. When the balloon pressure decreases,[link widoczny dla zalogowanych], the capsule polymer particles by the pressure of the outside air pressure slightly in the elastic deformation, the filler density, air bag hard to achieve the required strength of bone fixation. Figure 1.
1.2 fixed balloon materials and structures outside the sealed rubber nylon 0.35 mm, soft, good air tightness. Lined isolation filter, filter package within the polymer particles as a support body, the size of about 20 to 25 mesh. Fixed air bag tied with a fixed edge, tied with both ends of each length of 10 ~ 15 cm of the picture-button easy to pull for the airbag fixed limbs. Corner of the plastic bag sealed with vent, vent at the bottom of a mesh filtration device. Vent the top of the rope has lost connection with the anti-plastic soft plug. According to individual differences in body shape and design of the upper fixed (can also be used for the ankle),[link widoczny dla zalogowanych], leg fixed and body fixed three airbags. Detailed structure of Figure 2 to 4.
1.3 Making use of rubber nylon material as the main fixtures with high-frequency melting machine stitched into a sealed bag, in the polyethylene tube with one end of bag will balloon to control air pressure to form a channel. The root of the hose used in the mesh filtration device. Vent the top of the rope has lost connection with the anti-plastic soft plug. Appearance of the shape design based on a fixed part of the body made. Balloon built by the package size of the fabric sheet 20 to 25 the purpose of polymer plastic particles as a support body. Fixed air bag tied with a fixed edge, tied with both ends of each length of 10 ~ 15cm of the picture-easy to pull buckle.
1.4 Performance Parameters (1) fixtures can withstand the pressure 9.8 N/cm2; (2) appearance with a thickness of 0.35 mm PVC material, tensile strength was 40 N / cm ; (3) for temperature of 40 ℃ ~ -40 ℃, fixtures can withstand the pressure 9.8 N/cm2; (4) In normal circumstances, can be used repeatedly more than 1 000 times; (5) in the humidity of 65% to 70 % and ambient environment is valid for 8 years; (6) should be kept away from light, avoid heat, direct sunlight and contact with sharp objects and chemicals and over-extrusion, long-term storage should be stored in a small pocket of air to occurrence of anti-adhesion airbags. Pumping should be used to pump air inside the balloon a little more out in order to prevent the built-in polymer supports shift occurred in the transport transportation turn, influence the next use.
2 capsule aid device field of clinical application of bone
2.1 objects and grouping a total of 35 patients in this group, 21 males and 14 females; aged 15 to 61 years, mean 35 years. The overall use of fixtures in 6 cases, 17 cases of use of upper limb fixtures, the use of lower extremity fixation device in 12 cases. After the medical units sent to the appropriate post-processing.
Control the use of wooden splints, splint and bandage roll first aid evacuation of accident injuries. A total of 28 patients, 17 males and 11 females; aged 18 to 58 years, mean 32 years old. 6 cases of wooden splint use, the use of roll splint device in 10 cases, after the medical units sent to the appropriate post-processing.
2.2 application methods elbow dislocation in this group of cases, 1 case 2 cases of ankle dislocation, thoracic compression fractures 8,9,10 2 cases, lumbar compression 4,5 fracture in 2 cases, 1 case of pelvic fracture, tibia and fibula fractures in 10 cases, ulnar, radial fracture in 13 cases (including the closed Craven fracture), 2 cases of fracture of the lower humerus, femur fracture in 1, scapula fracture in 1.
Control group 1 case of elbow dislocation, dislocation of the ankle joint in 2 cases, 4 cases of fracture of tibia and fibula, radius and ulna fractures in 5 cases,[link widoczny dla zalogowanych], 2 cases of humeral fracture, femur fracture in 1, scapula fracture in 1.
Experimental balloon with fixed wooden splint, splint for roll control, the use of the limb bones, joints (35 cases, including 8 cases of wooden splint, splint roll 10 cases, the fixed air bag 17 cases), lower limb joints (23 cases, including wooden splint in 5 cases, 5 cases of roll splint, fixed air bag 13 cases), spine, pelvis (5 cases, including wooden splints 0 case, roll splint 0 cases,[link widoczny dla zalogowanych], the fixed balloon 5 cases) as the experimental injury, using the average operating time and complications as the evaluation index.
