Abstract
The invention discloses a novel mercury sphygmomanometer. According to the novel mercury sphygmomanometer, a traditional vent valve and a traditional connecting device are improved; a ventilation plug 17 is additionally arranged on the top end of a glass tube, and a safety post 13 is additionally arranged at the bottom of a meter box 16. The vent valve realizes control over the venting operation through the elastic force of a spring 3 and the gas pressure in a pipeline, so that the improved mercury sphygmomanometer can be used for measuring the blood pressure stably and precisely. The improved connecting device still can meet the balance rule of gas pressure in the pipeline, and with the improvement, the replacement of a cuff band 10 is facilitated, and the material is also saved. The ventilation plug 17 only has permeability on air, and the safety post 13 can prompt the state of a mercury switch, so that the overflow of mercury is effectively prevented.
Description
Technical field
The present invention relates to medical apparatus and instruments, particularly the present invention relates to one hand-held is sphygomanometer means of deflation, and this device can be realized the steady control of deflation course.After connected mode is improved, new connecting device can facilitate the replacing of sphygmomanometer sleeve bag, and reduces materials'use.The breather plug at the safety post in sphygomanometer watchcase and glass column top, effectively prevents that hydrargyrum from overflowing the generation of event.
Background technology
The means of deflation of sphygomanometer comprises air valve body, spring, piston.Existing sphygomanometer means of deflation comprises air valve body and thimble, and thimble contacts with air valve body by screw thread, and in the normal process using, thimble, by stopping up the steam vent on air valve body, reaches airtight effect; In the time that rotation thimble makes it no longer stop up steam vent, realize the object of aerofluxus.The weak point of this design is that exhaust process is sometimes fast and sometimes slow, and feel is not good is difficult to steadily control exhaust process.
The connected mode of existing mercurial sphygmomanometer is double hose, draws two slat gum pipes from the sidewall of sleeve bag, is connected respectively with sphygomanometers, inflatable ball.This connected mode weak point is: 1, need the two ends of separate rubber pipe simultaneously can change sleeve bag, make the replacing of sleeve bag more loaded down with trivial details.2, material is made in this connected mode waste.
The glass column apex structure of existing mercurial sphygmomanometer comprises passage, ventilative paper washer, can not effectively prevent overflowing of hydrargyrum, after mercoid switch uses, does not close also and does not point out.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above existing technological deficiency, and a kind of deflation device of handheld hemodynamometer is provided, and makes exhaust process more steady.New connecting device is simplified sleeve bag exchonge step and is saved material, contributes to the fixing of sleeve bag simultaneously.The safety post of setting up and breather plug can effectively prevent overflowing of hydrargyrum.
The technical solution used in the present invention is as follows:
A kind of deflation device of handheld hemodynamometer comprises: air valve body 1, spring 3, piston 2, it is characterized in that spring is arranged at piston upper bottom portion, and between piston and air valve body, be provided with O- ring seals 5,6, the both sides of air valve body are equipped with steam vent 4 and rubber fittings 7.
A kind of novel connecting device comprises: sleeve bag 10, rubber tube 9, Y-shaped tee T 8, its feature is only drawn a slat gum pipe at sleeve bag and is connected with the tail end of tee T, non-sphygomanometers 11 and the vent valve 12 of not connecting of two other head end of Y-shaped pipe.
A kind of assembly that prevents that hydrargyrum from overflowing comprises: safety post 13, breather plug 17, and what it is characterized in that the front of safety post adopts is U-lag 14 formulas designs, its top is positioned at mercoid switch 15 and closes on the movement locus that watchcase 16 is switches in open mode.Breather plug is placed in the top of glass column 18.
The invention has the beneficial effects as follows: the stiffness factor of the spring using is lower, the vent valve after improvement can eliminate that spiral vent valve is difficult to open or all to open the blood pressure measurement causing inaccurate moment.At pressurization gas replenishment process, breather plug only allows air to pass through, thereby prevents that hydrargyrum from overflowing.A variety of causes causes hydrargyrum to leak to glass tubing when not using, and breather plug also can prevent that hydrargyrum from overflowing outside glass tubing.Again in conjunction with the design of safety post, make to prevent that hydrargyrum from overflowing and had double shield.Single hose sleeve bag connecting device after improvement has been saved material on the one hand, the more important thing is that sleeve bag is changed becomes more convenient, can reach without changing inflatable ball the object of changing sleeve bag, be particularly useful for upper-arm circumference distribution large, need little same model sleeve bag to carry out the section office of blood pressure measurement, as department of pediatrics, outpatient service etc.

Detailed description of the invention
Below in conjunction with accompanying drawing, with embodiment, mercurial sphygmomanometer of the present invention is further described.
Embodiment 1
As shown in Figure 1, a kind of deflation device of handheld hemodynamometer comprises: air valve body 1, spring 3, piston 2, it is characterized in that spring is arranged at piston upper bottom portion, be provided with O- ring seals 5,6 between piston and air valve body, the both sides of air valve body are equipped with steam vent 4 and rubber fittings 7.When pressurization is that gas can enter sleeve bag 10 by two steam vents 4.After having pressurizeed, can discharge through steam vent 4 by the gas in lower piston 2 sleeve bag, under the effect of spring 3, auxiliary exhaust process steadily.
As shown in Figure 2, a kind of novel connecting device comprises: sleeve bag 10, rubber tube 9, Y-shaped tee T 8, its feature is only drawn a slat gum pipe at sleeve bag and is connected with the tail end of tee T, non-sphygomanometers 11 and the vent valve 12 of not connecting of two other head end of Y-shaped pipe.In the time that needs are changed sleeve bag, separate rubber tube 9 and Y-shaped tee T 8, can complete the replacing of sleeve bag.
As shown in Figure 3, a kind of assembly that prevents that hydrargyrum from overflowing comprises: safety post 13, breather plug 17, what it is characterized in that the front of safety post adopts is U-lag 14 formulas designs, and its top is positioned at mercoid switch 15 and closes on the movement locus that watchcase 16 is switches in open mode.Breather plug is placed in the top of glass column 18.When mercoid switch 15 is in open state, now close watchcase 16 switches 15 and can be subject to stopping of safety post 13, thus prompting operation person's closing mercury switch 15.
According to design of the present invention, its usefulness is: the stiffness factor of the spring using is lower, and the vent valve after improvement can eliminate that spiral vent valve is difficult to open or all to open the blood pressure measurement causing inaccurate moment.At pressurization gas replenishment process, breather plug only allows air to pass through, thereby prevents that hydrargyrum from overflowing.A variety of causes causes hydrargyrum to leak to glass tubing when not using, and breather plug also can prevent that hydrargyrum from overflowing outside glass tubing.Again in conjunction with the design of safety post, make to prevent that hydrargyrum from overflowing and had double shield.Single hose sleeve bag connecting device after improvement has been saved material on the one hand, the more important thing is that sleeve bag is changed becomes more convenient, can reach without changing inflatable ball the object of changing sleeve bag, be particularly useful for upper-arm circumference distribution large, need different model sleeve bag to carry out the section office of blood pressure measurement.
