Abstract
The utility model discloses a device for obtaining the blood pressure of a descending aorta by measuring the pulse wave of the descending aorta through an esophagus. The device comprises a photoelectric sensor (1), wherein the photoelectric sensor (1) is provided with an infrared ray emission tube (2) and an infrared ray receiving tube (3); the infrared ray emission tube (2) is connected with a power supply (4); the infrared ray receiving tube (3) is connected with a physiological recorder (5); and the physiological recorder (5) is connected with a computer (6). The device has the advantages of realizing dynamic monitoring of non-invasive/minimally invasive blood pressure for a special patient with deficiency of skeletal limb, large area of burns or microcirculatory disturbance, improving the tracking and reaction capabilities of blood pressure mutation and providing important theoretical basis for the preparation of rescue and treatment schemes. The blood pressure of the descending aorta obtained by the device has high relativity to a synchronous invasive arterial blood pressure, which indicates that the measurement of the blood pressure of the descending aorta through the esophagus has certain accuracy and reliability.
Description
Technical field
This utility model relates to a kind of device through esophagus survey descending aorta pulse wave acquisition descending aorta blood pressure, belongs to technical field of medical detection.
Background technology
Arteriotony is clinical diagnosis disease, observes therapeutic effect and carry out the important evidence that prognosis is judged.Usually non-invasive monitoring is adopted in the monitoring of blood pressure more in the prior art, and the measuring point of non-invasive blood pressure monitoring generally concentrates on shallow table tremulous pulse of human body periphery or extremity tip.But for some particular patients ', as: deficiency of skeletal limb, large-area burns or microcirculation is had the particular patients ' of obstacle, because can't lay monitoring device thereby also can't carry out promptly and accurately nothing/Wicresoft's ambulatory blood pressure monitoring, influence is to the timely judgement of the state of an illness and therapeutic effect.Therefore existing blood pressure detection method still can not satisfy the needs of reality.
Summary of the invention
The purpose of this utility model is: provide a kind of and survey the device that the descending aorta pulse wave obtains the descending aorta blood pressure through esophagus, with to deficiency of skeletal limb, large-area burns or have the particular patients ' of obstacle to provide a kind of to microcirculation to realize not having/dynamic monitoring of Wicresoft's blood pressure provides new method and device, thereby improve tracking, respond, for formulation is rescued, therapeutic scheme provides the important theory foundation to the sudden change of particular patients ' blood pressure.
This utility model is to constitute like this: a kind of used device of method through esophagus survey descending aorta pulse wave acquisition descending aorta blood pressure of the present utility model comprises photoelectric sensor, is provided with infrared emission tube and infrared receiver tube on photoelectric sensor; Infrared emission tube is connected with power supply, and infrared receiver tube is connected with physiograph, and physiograph is connected with computer.
Owing to adopted technique scheme, this utility model compared with prior art, method of the present utility model and device can or have the particular patients ' of obstacle to deficiency of skeletal limb, large-area burns to microcirculation, realize the dynamic monitoring of nothing/Wicresoft's blood pressure, can improve tracking, respond, for formulation is rescued, therapeutic scheme provides the important theory foundation to the blood pressure sudden change.The descending aorta blood pressure that this utility model obtained is compared with the wound arteriotony is arranged synchronously, and both dependencys are good, illustrate that measuring the descending aorta blood pressure through esophagus has certain accuracy and reliability.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
Embodiment of the present utility model:
Apparatus structure through esophagus survey descending aorta pulse wave acquisition descending aorta blood pressure of the present utility model is illustrated as shown in Figure 1, the used parts of this utility model device all adopt the component end item of selling on the existing market to assemble, comprise existing photoelectric sensor 1, on photoelectric sensor 1, install infrared emission tube 2 and infrared receiver tube 3; Infrared emission tube 2 is connected with power supply 4, infrared receiver tube 3 is connected with existing physiograph 5, physiograph 5 is connected with computer 6.
The method that adopts this utility model to carry out through esophagus survey descending aorta pulse wave acquisition descending aorta blood pressure is the position section that reflective photoelectric sensor is positioned over esophagus stage casing and descending aorta next-door neighbour from the oral cavity, obtain the characteristic parameter of descending aorta pulse wave continuously, go out the descending aorta blood pressure according to the blood pressure Equation for Calculating between descending aorta blood pressure and the descending aorta pulse wave characteristic parameters; Described descending aorta pulse wave characteristic parameters is to utilize the stepwise regression analysis method to screen from the parameter of a series of descending aorta pulse waves, is the characteristic parameter that close association is arranged with blood pressure; Comprise main wave height H, pulse wave characteristic quantity K, dicrotic notch relative altitude h/H and maximal velocity S(wherein h be the dicrotic notch height); Calculate the descending aorta blood pressure with following stepwise regression analysis equation according to the descending aorta pulse wave characteristic parameters then,

Feasibility analysis of the present utility model
The characteristics development that photoelectric sensor has light absorptive according to erythrocyte to infrared light, formed photoelectricity pulse wave shrinks with heart and diastole is periodically-varied.As converting light intensity to the signal of telecommunication, then can detect the variation of arterial volume, directly obtain the oscillogram of descending artery pulse wave.
This utility model is monitored the site with pulse wave and is transferred to descending aorta in the thoracic cavity by peripheral blood vessel, through esophagus obtain continuously, rule, descending aorta pulse wave stably, good with invasive blood pressure ripple synchronicity.Adopt the stepwise regression analysis method in this utility model, finishing screen is selected pulse wave characteristic quantity K, dicrotic notch relative altitude h/H, main ripple rate of rise S and four parameters of main wave height H as the characteristic parameter that calculates.Set up the stepwise regression analysis equation through esophagus photoelectricity pulse wave
