Abstract

The utility model provides a training device for automatically generating the lower body negative pressure, and comprises a telescopic lower body negative pressure tube 1, a sealing waistline 2, a shoulder belt 3, a handle 4 and other parts. The telescopic lower body negative pressure tube 1 has a deformable skeleton structure which is provided with the high air tightness and can be stretched up and down, the top end of the tube is connected with the sealing waistline 2, so as to ensure the sealing performance of the lower body negative pressure tube. The lower body negative pressure tube 1 is expanded through the shoulder belt 3 and the handle 4 to generate the negative pressure when a lower limb extends. The overstrain load of the lower limb and the negative pressure level can be controlled by adjusting the diameter of an inlet valve and the operational range of the lower body negative pressure tube 1. The device is integrated with the lower body negative pressure and the physical exercise into a whole, and the operation is convenient. The utility model can be used to develop the antigravity training and resist the physiological effect on the weightlessness.

Description

Lower body negative pressure training device voluntarily

The utility model relates to a kind of aircrew's trainer.

Utilize the human centrifuge to the aircrew train with improve the aircrew+G endurance, reduce loss of consciousness incidence, though this method has been subjected to generally paying attention to, human centrifuge's apparatus expensive is difficult to popularize.Therefore, study a kind of novel replenish or substituting anti-G training method and apparatus imperative.In recent years, the LBNP cabin of being designed by the LBNP principle is tempered method and has been proved to be a kind of effective anti-G training measure.But LBNP cabin volume is big, heaviness, and need attached power set, be not easy to aircrew's training and use.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of convenience, safe and effective lower body negative pressure training device to the aircrew---lower body negative pressure training device voluntarily.

The utlity model has following characteristics: need not the additionaling power device can produce LBNP voluntarily, integrate LBNP and physical training, in light weight, cost is low, wear off conveniently.Can be used for the aircrew and carry out anti-G training and antagonism weightleness physiological effect.

Realize that solution of the present invention is: the theory structure of the device of lower body negative pressure training voluntarily that is provided as shown in the figure.It partly is made up of scalable LBNP tube 1, sealing waistline 2, shoulder belt 3, handle 4, adjustable air intake valve 5, one-way exhaust valve door 6 and pressure gauge 7 etc.Now described in detail in conjunction with the accompanying drawings.

Fig. 1 is lower body negative pressure training device side view voluntarily.

Fig. 2 is lower body negative pressure training device top vertical view voluntarily.

With reference to accompanying drawing.The utility model is the airtight complete cavity housing of scalable LBNP tube 1 for being made of some belt steel rings 8 and gummed cloth 9 materials of lower body negative pressure training device voluntarily, can be arbitrarily flexible up and down.The steel ring 8 that goes in ring constitutes skeleton, and the appearance of skeleton is covered with gummed cloth 9 materials of high strength, high-air-tightness.The tube end is a steel plate 10.LBNP tube top is pasted with annular rubber shroud 2, and its inwall is pasted with annular air-pocket 11.Certain position is connected to unidirectional inflation valve joint 12 on the LBNP tube, communicate with annular air-pocket 11, by unidirectional inflation valve joint 12, can be to annular air-pocket 11 inflations, make annular rubber shroud 2 and annular air-pocket 11 be close to the human body waist, to guarantee the sealing property of LBNP tube.Certain position of LBNP tube top front is also designed respectively adjustable air intake valve 5, one-way exhaust valve door 6 and pressure gauge 7, and they all communicate with the inner chamber body of LBNP tube.Braces 3 is made by high strength blending cloth and formed, and is customized in the both sides of LBNP tube top ports.Handle 4 is made by stainless steel material, is fixed in the both sides of LBNP tube top ports.

During operation, experimenter's lower body places in this negative pressure cylinder, gets upright position or clinostatism.Adjust and tighten the annular rubber shroud 2 of waist, make annular air-pocket 11 sufficient gas, to guarantee the air-tightness of LBNP tube.When experimenter's lower limb stretch (Fig. 1 b), one-way exhaust valve door 6 is closed, and adjustable air intake valve 5 parts are opened or closed, and by shoulder belt 3 and handle 4 the LBNP tube is expanded and produces negative pressure.Lower limb firmly load can be controlled by regulating air intake valve 5 bores and LBNP tube operating range with the interior pressure-reduction level of tube; (Fig. 1 a), one-way exhaust valve door 6 is open, the atrophy of LBNP tube during the lower limb flexing.Can monitor the LBNP cylinder pressure in real time by pressure gauge 7.The experimenter constantly repeats to do the lower limb flexion and extension, and the LBNP tube is constantly expanded/atrophy, can produce intermittent negative pressure in the LBNP tube, is used to carry out lower body negative pressure training.
