Abstract
The invention relates to a screwed-in capillary pressure measuring device comprising a spiral screwed-in device. A screwed-in handle is rotatably connected to the exterior of a threaded rod; the side surface of the screwed-in handle is fixedly connected with a vertical linkage rod and a pressure sensor; the pressure sensor is installed on the bottom of the vertical linkage rod and is connected with a display system lead; the bottom of the pressure sensor is provided with a precise lever, one end of the precise lever is connected with the pressure sensor, and the other end of the precise lever is provided with a transparent tabletting arranged on a capillary to be measured; and the fulcrum of the lever is near one side of the pressure sensor. The screwed-in capillary pressure measuring device has the advantages of accurate measurement, good repeatability and excellent popularization value, and is rapid and convenient in operation; and a client feels comfortable when the device provided by the invention is used.
Description
Technical field
The present invention relates to a kind of measuring device, specifically a kind of screw type blood capillary pressure measuring device.
Background technology
The variation of CP can directly change the blood capillary function, influences the local organization blood supply, so blood capillary pressure is an important indicator of microcirculation function state.But still there is not a kind of CP measuring method that is fit to clinical use at present.Once reported the measuring method of carrying out CP with micro-arena pipe and servo zeroing measuring cell abroad, but the method there is damage to body, and involves great expense.Units such as domestic 301 Hospital also once designed Mainspring type hair vascular pressure measuring instrument, and this device uses clockwork feed, indicating graduation dish to realize the measurement of first folds in a garment CP, also has adopts pressure sensor to realize digital measurement.But owing to adopt clockwork spring and graduated disc structure to realize the measurement of minute-pressure power, the influence factor is many, and precision is limited.
CP is a pressure unit, and pressure must vertically act on the capillary wall.Because measuring CP must observe by microcirculation microscope, thereby cause pressure exerting arrangement and microscope can not be added in simultaneously on the first folds in a garment blood capillary, must be by lever principle, to exert pressure and be transmitted to pressure measxurement mechanism, the clockwork spring that tightens can only provide and screw elastic force, and this just causes the inaccurate of pressure at right angle measurement.
Summary of the invention
In order to solve some unfavorable problems that existing CP measuring technique exists, a kind of screw type blood capillary pressure measuring device provided by the invention is swift to operate, measure accurately, good reproducibility, person under inspection are comfortable, has promotional value.
The technical solution adopted for the present invention to solve the technical problems is: this screw type blood capillary pressure measuring device comprises threaded rod, precession handle, vertical trace, pressure transducer, Data Acquisition And Display System, accurate lever, microscope; This measuring device has a spiral precession device, and it is to be connected with the precession handle that can be shifted up and down in the rotation of the outside of a threaded rod; The side of this precession handle is fixedly connected with vertical trace and pressure transducer, this pressure transducer is installed in the bottom of vertical trace and is connected with the Data Acquisition And Display System lead, the transfer of data that records is analyzed to Data Acquisition And Display System and is shown; This pressure transducer bottom is provided with an accurate lever, and this precision lever one end is connected with pressure transducer, and the other end is provided with transparent tabletting, is placed on the blood capillary to be measured, and the fulcrum of lever is used for the sensitivity that pressurize is measured near pressure transducer one side; Correspondence is provided with microscope on this blood capillary to be measured, so that observe the clear condition of measurement and the blur-free imaging of blood capillary.
The invention has the beneficial effects as follows: this screw type blood capillary pressure measuring device screw type blood capillary pressure measuring device is swift to operate, measure accurately, good reproducibility, person under inspection are comfortable, has promotional value.
