The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
As Fig. 1 to Fig. 4, the two valve arm band airbag structures of a kind of sphygomanometer, comprise airbag body 10 and two gas nozzle structures 13, two gas nozzle structures 13 comprise two identical valves, each valve middle part is columniform valve body 4, each valve head is provided with taper 2, each taper 2 bottom be cylinder 3, be provided with manhole 7 in each valve; Two gas nozzle structures 13 and airbag body 10 weldings.
The tapering of each taper 2 is 70～85 degree.Each taper 2 top is provided with top rounding 1.Each valve body 4 bottom is provided with bevelling 5.Each 5 below, bevelling is valve bottom 8, and valve bottom 8 is one 8 font platforms, connects two identical valves respectively on the valve bottom 8.Each valve bottom 8 side towards the valve head has valve bottom rounding 6.The thickness of valve bottom 8 is about 0.5～0.8mm.
The material of two gas nozzle structures 13 is a Polyurethane Thermoplastic Elastomer rubber.
This arm belt sphygomanometers air bag adopts the TPU material, i.e. thermoplastic polyurethane elastomer rubber, and overall structure is made of airbag body and two valves.
The structure of valve as shown in Figure 1 and Figure 2, two gas nozzle structures 13 contain two identical valves of geomery, with being connected of what air bag and trachea.Be used for being connected of air bag and trachea.Its head is a taper 2, tapering is 75～80 degree, taper 2 tops are provided with top rounding 1, what be right after taper 2 is a cylinder 3, valve body 4 is cylindrical, and its external diameter is smaller than top external diameter, and above structure and shape be the assembling of what trachea just, can guarantee good airtight and make valve and joint possess the enough power that is connected, when avoiding using and trachea come off.Valve body 4 bottoms are provided with bevelling 5, and just the what valve penetrates airbag body.Valve bottom 8 is a circular platform, it is the junction of valve and air bag welding, its side towards valve has rounding 6, when making thermal welding, the face of weld material has sufficient contact, and its thickness is about 0.5～0.8mm, has good welding effect, whole valve is provided with manhole 7, is the passage of gas turnover air bag.This platform adopts special abnormity design, and the face of weld that can satisfy after the welding bending is neat rule, and makes that the welding bending is more stable, thoroughly.
