Description
The utility model relates to mercurial sphygmomanometer with anti-hydrargyrum spill and leakage device.
At present, the widely used blood pressure of health system is counted mercury sphygmomanometer (mercurial sphygmomanometer), but there is hydrargyrum spill and leakage defective, promptly in sphygomanometer moves or mercury column rise when too much exceeding glass tubing top venthole, hydrargyrum is outside venthole overflows sphygomanometer, although a manually-operated gate is housed between mercury pool and glass tubing, but because of it uses inconvenience, user is not often noted valve-off, causes seriously contaminated environment not only of hydrargyrum spill and leakage, and causes sphygomanometer inaccurate.
The purpose of this utility model is the weak point that exists at above-mentioned sphygomanometer, and a kind of novel mercurial sphygmomanometer is provided, and adopts floating plug formula venthole, lid interlock valve, hydrargyrum spills when too much causing the hydrargyrum spill and leakage and moving sphygomanometer can to prevent mercury column to rise, and it is simple in structure, and effect is remarkable.
Novel mercurial sphygmomanometer takes following scheme to realize: the mercurial sphygmomanometer primary structure is become by sphygomanometer box, lid, rule, glass tubing, floating plug formula venthole device, interstage valve, mercury pool, cuff, the set of balls of calming the anger.The sphygomanometer box cover has lid, the end of the two adopts two fulcrums to link, lid closes when not using, lid goes to lid around fulcrum and is 90 ° during use, the lid inner face is fixed with glass tubing, and the glass tubing both sides is fixed with rule, the glass tubing upper end is connected with floating plug formula venthole device, and the lower end connects interstage valve and is connected with mercury pool, cuff joins by conduit and mercury pool, and the ball of calming the anger is connected on the cuff joint by conduit.Floating plug formula venthole device has Xiao Chi, and the Xiao Chi top is taper, and the top has venthole, is placed with the taper floating plug of a hollow in the Xiao Chi, and the floating plug bottom is connected with little of cross.Interstage valve is made of valve body, spool, valve rod, spring, connecting axle, and valve body is three-way shape, is processed with to be communicated with glass tubing through hole and mercury pool through hole, and the rear portion is processed with taper hole, and spool is assemblied in valve body taper hole one end.Spool has tapering, and the spool front portion is processed with " L " shape valve core channel, and promptly the through hole on spool communicates with mercury pool, is communicated with at spool and valve body to be processed with through hole on the conical surface that the glass tubing through hole matches and to be communicated with the spool front end.The spool rear portion is processed with the valve rod hole that valve rod and spring are installed, valve rod is contained in the valve rod hole, and front end is equipped with spring, and connecting axle is installed in the valve rod rear portion and is fixed on the sphygomanometer box one end outside, can be used as one of two fulcrums of sphygomanometer box and lid, lid can rotate around the axis.
Novel mercurial sphygmomanometer is owing to adopt floating plug control venthole, in the time of can preventing the sphygomanometer improper use, the hydrargyrum spill and leakage that mercury column rises and too much causes, interstage valve is valve-off when stopping using sphygomanometer back box upper box cover, and hydrargyrum spills when preventing to move mercurial sphygmomanometer.To increase part simple structure, handling ease, cost not high not changing original sphygomanometer principle and basic structure for this sphygomanometer, can solve hydrargyrum spill and leakage problem fully, and effect is remarkable.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is novel mercurial sphygmomanometer structural representation.
Fig. 2 is this utility model floating plug formula venthole apparatus structure sketch map.
Fig. 3 is the floating plug structural representation of this utility model floating plug formula venthole device
Fig. 4 is this utility model interstage valve structure and scheme of installation.
Have sphygomanometer box (10) with reference to the novel mercurial sphygmomanometer of accompanying drawing, lid (4) is contained in an end of box, adopts two moving fulcrums, and the connecting axle of interstage valve (6) is an interim fulcrum.Glass tubing (2) is fixed on lid (4) middle part, both sides are fixed with rule (3), floating plug formula venthole device is equipped with in the glass tubing upper end, this device is outside to be taper Xiao Chi (1), the Xiao Chi summit is processed with venthole (11), Xiao Chi top taper, place the taper floating plug (12) of a hollow in the Xiao Chi, the floating plug profile is corresponding with the Xiao Chi inner chamber littler, the floating plug top tip part points to venthole (11) all the time, and can be up and down in Xiao Chi, and floating plug (12) bottom connects little an of cross (13), during normal the use, floating plug is held on Xiao Chi (1) bottom by little (13); The interior air of glass tubing (2) is subjected to the pressure influence of mercury column lifting can be through the space between little, Xiao Chi and the floating plug, venthole (11) frees in and out, in case hydrargyrum rises too much, charge in the Xiao Chi (1), floating plug (12) is subjected to the buoyancy top to block venthole in order to avoid hydrargyrum is excessive to venthole (11).Glass tubing (2) lower end is installed on the interstage valve valve body (9), and mercury pool (5) is connected with valve body, cuff (17) joins by sebific duct and mercury pool (5) top, and the ball of calming the anger is contained on the cuff pressure pipe joint by sebific duct.During use, the hydrargyrum of storing in the mercury pool (5) is subjected to cuff, the pressure of the ball of calming the anger in interstage valve people glass tubing (2), rise to certain altitude, read scale value and promptly measure this pressure.In accompanying drawing 4 structures and scheme of installation, interstage valve connecting axle (6) is one of two fulcrums of lid (4) and mercurial sphygmomanometer box (10), one end of axle is fixed on the lateral wall of sphygomanometer box (10), lid can rotate around connecting axle (6), connecting axle connects valve rod (7), the cross section of valve rod is square or is arc, and stretch among the valve rod hole of spool (8), the valve rod hole cavity shape matches with valve rod (7) profile, valve rod can endwisely slip, spring (14) is equipped with in valve rod (7) front portion, make between spool and valve body (9) taper hole certain pressure is arranged, to guarantee the sealing between spool and the valve body, valve body (9) is fixed on lid (4) bottom, and the other end of spool (8) has " L " shape valve core channel (15).Lid and sphygomanometer box (10) are 90 ° during user mode, valve core channel (15) two ends be communicated with glass tubing (2) respectively and lead to mercury pool (5) and passage (16), this moment, valve was open-minded, and hydrargyrum flows between mercury pool (5), passage (16), valve core channel (15), glass tubing (2).The time spent lid (4) that closes not, the valve body (9) that is fixed on the lid also sways, and spool (8) is because valve rod (7), connecting axle (6) restriction is relative to not rotating, stagger in the glass tubing via openings place of the opening of valve core channel (15) and valve body (9), valve cuts out, and hydrargyrum can not flow.Valve-off when stopping using sphygomanometer to close lid like this, thus hydrargyrum spills when preventing to move mercurial sphygmomanometer after stopping using sphygomanometer.
