Description

ESF1GMOMANOMETER CAPSULAR FOR MEASURING THE BLOOD PRESSURE OBJECT OF THE INVENTION The present invention, as expressed in the title of this specification, refers to a device comprising a sphygmomanometer or tensiometer 5 capsular to measure the blood pressure that is confused by a mercury or aneroid manometer, to measure the applied air pressure, also has a device with inflatable bag that hugs any limb, in which you want to take blood pressure, has also a rubber pump used to inflate this device and a connector tube, a four-diaphragm stethoscope or capsules placed in said device with the purpose of accurately capturing the pulsations of the bloodstream, incorporated in said device, and performed in order to obtain numerous and notable advantages with respect to other existing means of similar aims. The device is designed so that through its performance the four diaphragms or capsules can detect the pulsations of the heart at various points of the device with 5 inflatable bags taking simultaneous readings in several arteries at once, that is, if the device is placed in the forearm of the patient, these capsules will simultaneously take the pulsations in the ulnar artery as in the radial artery with greater precision than in conventional devices that have only a single capsule. BACKGROUND OF THE INVENTION 0 The circulatory system is similar to a hydraulic system in which the pump drives the liquid is the heart, the tubes are the arteries that in the human being are elastic and the liquid is the blood. For blood to circulate normally through the body it is necessary to do so with a certain pressure, this pressure is due to the effect of the heart's expulsive pump. The pressure of blood within the arterial system is called blood pressure and can be measured in our arms and legs with devices called a sphygmomanometer, the oldest are the mercury column and the aneroid type that consists of a system for exert pressure of the arm or leg and a scale that allows to know the pressure applied from the outside.

All sphygmomanometers or tensiometers are constituted by a mercury or aneroid manometer to measure the air pressure applied, a commonly called bracelet, to be placed both on the arm and on the leg, as desired with a length that covers the arm transversally or the patient's leg, a rubber pump that inflates the bag with air inside the cuff, a connecting tube that connects the pump with the bag, and a stethoscope, whose diaphragm is placed between the area corresponding to the artery and the said bag . All these systems have the disadvantage that the blood pressure readings are made by means of a single diaphragm or capsule so that its reading is subject to many position factors of the same, without taking into account the areas surrounding the blood pressure. artery, while this pressure is taken only in a single artery so it lends itself to erroneous and inaccurate reading. DESCRIPTION OF THE INVENTION The device of the invention has a new structure able to adapt transversely to the periphery of the arm or pyran to which it is desired to measure blood pressure, which has four diaphragms connected to each other in such a way that they can capture the pulsations of the heart, not only when they are directly placed in front of the artery but they can pick up those pulsations in the periphery of the same one, being able also captor pulsations in simultaneous form in two arteries. More specifically, this device consists of four diaphragms placed longitudinally through the bracelet that cover transversely the entire surface of the arm or leg whose width multiplied by 2.5 should be equal to the circumference of the arm or leg of the patient, said diaphragms connected in parallel are connected by a hose to the headphones of the stethoscope. Describing more precisely the annexes of the four diaphragms it can be considered that the first two diaphragms are connected in parallel, in order to capture the pulsation of the artery in the entire area where it is reflected, which in turn the other two diaphragms also connected in parallel if they can simultaneously capture the pulsation in another artery, where the result is synthesized by joining these two groups by half of two tobos that connect them together in parallel carrying the signal to the four diaphragm stethoscope. To complement the description that will be made next and with the object of helping to better understand the characteristics of the invention, the descriptive specification of a drawing is attached, wherein the innovations and advantages of the device object of the invention will be more easily understood. the invention. BRIEF DESCRIPTION OF THE DRAWING Unique Figure.- Shows the disposition of the elements of this device in diagranatic form, where it is possible to clearly observe the connections of the four diaphragms placed in the bag which simultaneously capture the pulsations of the arteries that are registered by the stethoscope, also has an inflatable bulb connected in parallel with an aneroid. REFERENT REALIZATION OF THE INVENTION In view of the single figure, it can be seen how the device is constituted by a rectangular configuration bag made of soft material that is not aggressive to the skin and can be made of fabric with these characteristics inside this fabric. bag of elastic characteristics of polyurethane, neoprene, rubber or similar material that can retain the air sent by the rubber bulb or any elastic material that does not allow the filtration of air between the rubber bag and the cloth bag where the Diaphragms that are thin membranes of some rigid material. As can be seen in the figure there is a rectangular fabric bag (1) which contains inside a bag of smaller rubber dimension (2), between the cloth bag (1) and the rubber bag (2) ), they are placed in longitudinal form as shown in the figure the four diaphragms (3), (4), (5) and (6), in turn the diaphragm (3) is connected in parallel with the diaphragm (4) ) through the tube (7), and the diaphragm (5) is connected in parallel with the diaphragm (6) through the tube (8), where the tubes (7) and (S) connect these two groups in parallel to each other. Through the tube (9) and the stethoscope (10), the rubber bulb (12) is directly connected to the rubber bag (2) through the
