Abstract
The utility model is a non-mercury sphygmomanometer belonging to medical products, which comprises a liquid storage cavity attached with an air inlet and a display pipe communicated with the liquid storage cavity. Display liquid is stored in the liquid storage cavity and the display pipe. The utility model is characterized in that: upper end of the display pipe opens, the liquid storage cavity is internally positioned with a balancing weight consistent with the cavity section in shape and matched with its side face; side face of the balancing weight can be added with a sealing ring. The utility model displays people's blood pressure by the joint function of the balancing weight and the liquid. By utilizing the structure of the utility model, the liquid used by the sphygmomanometer can be changed into common liquid, thus substantially lowering the sphygmomanometer's cost and eliminating the potential threat to human as well as the pollution to environment from the mercury when producing and utilizing the existing sphygmomanometer; in addition, the utility model is also characterized in simple structure and easy for processing.
Description
Technical field
This utility model is a kind of mercury-free type blood-pressure meter, belongs to a kind of medical supplies.
Background technology
The present fluid column formula sphygomanometer that uses in the medical treatment generally all for hydrargyrum (hydrargyrum) formula is arranged, utilizes that mercury metal density is big, the characteristics of good fluidity, pressure value is shown as the height of the mercury column that produces same pressure, about every mercurous 50 of this sphygomanometer restrains.But because mercury metal is volatile toxic, so there are manufacturing, maintenance and the use of hydrargyrum formula sphygomanometer to bring a lot of inconvenience; In addition since the oxide that the inwall of this kind sphygomanometer display tube also is easy to adhesion metal hydrargyrum with and color not obvious, often influence the accuracy of reading.
Summary of the invention
This utility model designed a kind of simple in structure, keep and easy to use and can use other mercury-free type blood-pressure meter that shows liquid, solve simultaneously and reduce hydrargyrum, and reduce the pollution of hydrargyrum environment to the potential threat of human body.
This utility model comprises liquid storage cylinder that has air inlet and the display tube that communicates with liquid storage cylinder, demonstration liquid is arranged in liquid storage cylinder and the display tube, its technical scheme is: the display tube upper end open, being equipped with in liquid storage cylinder can balancing weight consistent with its intracavity section shape and that cooperate with its side.The side of balancing weight can install sealing ring additional.This utility model uses balancing weight and liquid combined effect to show people's blood pressure.The liquid that utilizes this structure of the present utility model just sphygomanometer can be used change common liq (utilizing the oils liquid that adds color) into, and this just can significantly reduce the cost of sphygomanometer, can also remove produce and when using existing sphygomanometer hydrargyrum to the potential threat of human body and to the pollution of environment.In addition, this utility model simple in structure in addition, be easy to machining characteristics.
The air inlet of this utility model liquid storage cylinder can be positioned on its bottom surface, also can be located at its side, but at this moment, the position-limit mechanism of balancing weight is set in liquid storage cylinder, is located at the top of air inlet.This position-limit mechanism can be inner protuberant ring or spacing projection.
Description of drawings
Fig. 1 is the partial cutaway view of this utility model embodiment;
Among the figure: 1, liquid storage cylinder, 2, show liquid, 3, display tube, 4, balancing weight, 5, spacing projection, 6, air inlet.
The specific embodiment
As shown in the figure, present embodiment by the liquid storage cylinder 1 of cylindricality, be installed in movable balance weight piece 4, liquid storage cylinder 1 top communicate with it in the liquid storage cylinder 1 display tube 3 and the demonstration liquid 2 in liquid storage cylinder 1 and the display tube 3 is formed.Wherein, the upper end open of display tube 3, the sealing gasket pressing is adopted on the top of lower end and liquid storage cylinder 1.The side of liquid storage cylinder 1 bottom has air inlet 6, and the balancing weight consistent with its shape of cross section 4 is housed in the liquid storage cylinder 1, has spacing projection 5 on liquid storage cylinder 1 inwall between balancing weight 4 and the air inlet 5.
Claims (3)
