Utility model content
This utility model is to overcome deficiency of the prior art, a kind of human body lower body negative pressure device is provided, the frame structure that soft bag periphery arranges purchasing ore can for convenience detachly be assembled, soft bag is played a supporting role, can ensure that lower body negative pressure device quantitatively changes the function of blood volume at people's distribution in vivo.
This utility model for achieving the above object, be achieved through the following technical solutions, a kind of human body lower body negative pressure device, it is characterized in that: comprise vacuum pump, surge tank, negative pressure cab and operating board, described vacuum pump is connected with surge tank by on-off valve, surge tank is connected with negative pressure cab by control valve, described negative pressure cab comprises purchasing ore and soft bag, described purchasing ore is type solid frame structure, described soft bag is suitable for reading is provided with the apron with human body waist seal, described soft bag is placed in exo-skeletal, soft bag periphery is connected with purchasing ore by the connecting band affixed with it, described soft bag bottom is provided with the gas path pipe interface be connected with surge tank and control valve.
Described purchasing ore adopts timber, plastic material or shape to be assembled into frame-type purchasing ore, and its shape of cross section is rounded, oval or square.
Described soft bag adopts PUV material, and its shape of cross section is rounded or oval.
Described soft bag volume is 0.5-1m
3.
Beneficial effect: compared with prior art, the purchasing ore of soft bag periphery design frame structure of the present utility model can for convenience detachly be assembled, soft bag is played a supporting role, when purchasing ore constant dynamic, only change the size of soft bag, just can be applicable to different tested crowds, such as adult and child.Integrally-built simplification makes cost greatly reduce.

Detailed description of the invention
Below in conjunction with preferred embodiment, to the detailed description of the invention provided according to this utility model, details are as follows: embodiment
Refer to accompanying drawing 1, 2, the present embodiment provides a kind of human body lower body negative pressure device, comprise vacuum pump 9, surge tank 10, negative pressure cab 11 and operating board 12, described vacuum pump is connected with surge tank by on-off valve 1, surge tank is connected with negative pressure cab by control valve 3, Bonding pressure table 2 on surge tank, described negative pressure cab comprises purchasing ore 7 and soft bag 6, described purchasing ore is type solid frame structure, described soft bag is suitable for reading is provided with the apron 5 with human body waist seal, the overall structure of the soft bag of the present embodiment is oblong body, an end face is airtight, another end face opening, mouth is provided with apron, after human body pierces soft bag, more than waist expose, apron and waist laminating.Described soft bag is placed in exo-skeletal, and soft bag periphery is connected with purchasing ore by the connecting band 8 affixed with it, and described soft bag bottom is provided with the gas path pipe interface 4 of the routine be connected with surge tank and control valve.The present embodiment, meanwhile, also has another one gas path pipe interface, and this interface installs vacuum table 13 to show negative pressure value, and vacuum table can be stem-winder, also can be electronic watch.On-off valve, vacuum table, Pressure gauge and control valve are arranged on operating board 12.
Described purchasing ore adopts timber, plastic material or shape to be assembled into frame-type purchasing ore, and its shape of cross section is rounded, oval or square.The present embodiment, purchasing ore adopts angle steel to connect and compose quadra by bolt.
It is airtight that described soft bag adopts soft bag to adopt, and have stronger tear-resistant and draw the PUV material of ability to form, and its shape of cross section is rounded or oval.Diameter can be determined according to body dimension, for adult, can be designed as 700-800mm, if oval, its major axis dimension is 700-800mm, minor axis dimension is 450-550mm, highly can be designed as 800-1000mm, the size of the apron part of soft bag can correspondingly reduce, and is highly 200-300mm, the sealing of apron and human body waist adopts existing structure, also can be bonded at human skin with the dressing paste of sanitation-grade.Soft bag be processed as conventional heat seal process, along soft bag circumferencial direction heat seal eight row connecting band, the other one end of connecting band directly ties up on purchasing ore.The volume of soft bag, according to soft bag negative pressure variation Speed Setting, is generally 0.5-1m
