Abstract
The invention provides a portable standing position stress simulator used in space flight, which is composed of a power and control device, a retraceable negative pressure device and a support device, wherein the power and control device is used for providing negative pressure and pressure control; the retraceable negative pressure device is used for providing a negative pressure environment; and the support device is used for providing support and fixation for the retraceable negative pressure device. The portable standing position stress simulator can simulate the standing position stress, thereby detecting the standing position endurance and evaluating the cardiovascular function of the astronaut; and the portable standing position stress simulator can be stored separately, and thus, is convenient for transportation and storage.
Description
Affiliated technical field
The present invention relates to a kind of spacefarer's cardiovascular function checkout gear.
Background technology
Weightlessness during space travel can cause that adaptive change appears in each system of human body, comprises cardiovascular dysfunction, amyotrophy and bone loss etc.The U.S. has proposed to realize the manned new space program of landing Mars in mid-term 1930's that China has also proposed to set up the development plan of space station and survey of deep space.Therefore, in the manned space flight task in future, the spacefarer will stop the longer time in the weightlessness of space environment, and weightless will be more serious to the adverse effect of human body.
For ensureing spacefarer's health, safety and work efficiency, except that must the necessary Medical Instruments of space station configuration, also being equipped with special checkout equipment.It is to assess the special method of spacefarer's cardiovascular function in-flight that orthostatic tolerance detects, and mainly utilizing the simulation of tilt table and LBNP device to stand the position at present on ground stress.Because tilt table and LBNP device (like lower body negative pressure cabin) volume are big, Heavy Weight, complex operation does not suit on the space station of Future in China, to use.Therefore, it is stress analog very necessary to study a kind of portable upright position.
Summary of the invention
Existing upright position is stress the analog volume big, Heavy Weight, complex operation.In order to overcome the problems referred to above of existence, the present invention provides a kind of novel portable that is suitable on the space station, using to stand the position stress analog.
The technical solution adopted for the present invention to solve the technical problems is: portable upright position stress be made up of power and control device, telescopic negative pressure device and bracing or strutting arrangement three parts by analog; Power and control device are used to provide negative pressure and pressure control; Telescopic negative pressure device is used to provide subnormal ambient, and bracing or strutting arrangement is used for for telescopic negative pressure device necessary support and fixing being provided.
The invention has the beneficial effects as follows: during use with power and control device, telescopic negative pressure device and bracing or strutting arrangement three parts fit together can simulate upright position stress, carry out orthostatic tolerance and detect; When not using power and control device, telescopic negative pressure device separated with bracing or strutting arrangement three parts and deposit, be convenient to transportation and storage.

The specific embodiment
In Fig. 1, portable upright position stress be made up of bracing or strutting arrangement, telescopic negative pressure device and power and control device (7) three parts by analog.Bracing or strutting arrangement is made up of base (14) and expansion link (11), and base (14) is the circular glass steel construction, and expansion link (11) is for being similar to the multistage Circular Rigid structure of telescopic antenna formula.One end of expansion link (11) is fixed on the both sides of the edge of base (14), and the other end can be drawn out to setting height and fixing as required, for cylindrical shell (10) provides support.Telescopic negative pressure device is made up of tube top (1), cylindrical shell (10), the tube end (13) and sealing shroud (2).Tube top (1) and the tube end (13) are the circular glass steel construction, the telescopic rounded cylindrical structure of cylindrical shell (10) for surrounding by gummed cloth, and the rigid circular Os Draconis (12) by a plurality of parallel dischargings in the cylindrical shell (10) provide support.Cylindrical shell (10) one ends link to each other with the tube end (13), and the other end links to each other with tube top (1).Tube top (1) central authorities reserve an elliptical openings, and elliptical openings links to each other with sealing shroud (2).(1) proximal edge place, tube top is reserved with aspirating hole (3) and pressure tap (8), and (1) both sides, tube top respectively connect a grip (9).Power and control device (7) are made up of minipump, pressure detecting and control device, and an end of pressure hose (4) links to each other with pressure tap (5) with aspirating hole (6) on it.
During use, at first with the tube end (13) of telescopic negative pressure device through on the base (14) that is bolted to bracing or strutting arrangement, let a trainee stand in the telescopic negative pressure device then, cylindrical shell is pulled to xiphoid-process under and encloses with sealing shroud (2).The expansion link (11) of bracing or strutting arrangement is pulled to correct position and fixing, then the handle (9) on the cylindrical shell (10) is fixed on expansion link (11) upper end.The other end of pressure hose (4) is connected with pressure tap (8) with the aspirating hole (3) that tube pushes up on (1) respectively.Utilize power and control device (7) to set needed pressure, start power and control device and start working, treat cylindrical shell (10) when internal pressure reaches setting value power and control device (7) quit work automatically.Power and control device are controlled cylinder internal pressure automatically and are maintained set point.
After using end; At first unclamp the cylindrical shell handle (9) that is fixed on expansion link (11) upper end; Regain expansion link (11) and cylindrical shell (10) respectively, unclamp the bolt of (13) and base (14) at the bottom of the stationary magazine creel then, break off aspirating hole (3) and the pressure hose (4) of pressure tap (8) on the connecting cylinder top (1); Bracing or strutting arrangement, telescopic negative pressure device and power and control device (7) three parts are separated deposit, be convenient to transportation and storage.
Claims (1)
1. a portable upright position stress analog; Form by bracing or strutting arrangement, telescopic negative pressure device and power and control device (7) three parts; It is characterized in that: bracing or strutting arrangement provides support and fixes for telescopic negative pressure device through base (14) and expansion link (11); Telescopic negative pressure device is formed telescopic cylindric hermetically-sealed construction by tube top (1), cylindrical shell (10), the tube end (13) and sealing shroud (2); Power and control device (7) provide the control of negative pressure and pressure for telescopic negative pressure device, bracing or strutting arrangement, telescopic negative pressure device and power and control device (7) three parts are separable independently deposits, and can simulate upright position after the combination stress.
