Abstract
The invention discloses a pressure measuring catheter, which comprises a catheter body, wherein the end part of the catheter body is provided with a pressure sensor, the end part of the catheter body is provided with the pressure sensor, so that the blood pressure at the end part of the catheter can be detected in real time, the detection accuracy is high, real-time feedback can be provided for an operation, a surgeon can conveniently monitor the state of a patient in real time and adjust a treatment scheme, and the pressure measuring catheter has higher practical value.
Description
Technical field
The present invention relates to a kind of pressure catheter be used as on clinical medicine.
Background technology
When carrying out the operation of some Wicresofts, usual needs penetrate seal wire or conduit at the Ink vessel transfusing of human body, other vital signs such as data such as blood pressure, heart beating of human body then need other configuration device to gather, but when Measure blood pressure, external equipment cannot get the real-time blood pressure that seal wire or end of conduit are carrying out the position for the treatment of or performing the operation accurately, be difficult to the state getting operative site really, accurately, the carrying out of operation is affected.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of pressure catheter.
The technical solution adopted for the present invention to solve the technical problems is:
Pressure catheter, comprises catheter body, and described catheter body end is provided with pressure transducer.
Described catheter body comprises body and is arranged on the seal wire in body.
Described pressure transducer is arranged on body.
Described pressure transducer is arranged on seal wire end.
Described body is also provided with some stripeds with the scale that makes a check mark.
Described seal wire is arranged with the screw-casing be made up of helical form steel wire.
The invention has the beneficial effects as follows: the present invention is by arranging blood pressure end of conduit being detected that pressure transducer can be real-time in catheter body end, and accuracy in detection is high, real-time feedback can be provided to operation, the monitored patient state facilitating operative doctor real-time and adjustment therapeutic scheme, have higher practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 1 is the structural representation of the present invention's specific embodiment, as shown in the figure, pressure catheter, comprise catheter body, described catheter body end is provided with pressure transducer 3, this pressure transducer can adopt Dun Li company (Medtronic, Inc.) active wireless pressure transducer (activeleadless pressuresensor, be called for short ALPS), so that wireless receiving pressure signal, certainly other capacitive pressure sensor can also be adopted, as Sensors and Actuators A:Physical Vol73, Issues1-2, 9March1999, described in Pages58-67, do not describe in detail one by one at this, the present invention is by arranging blood pressure end of conduit being detected that pressure transducer can be real-time in catheter body end, and accuracy in detection is high, real-time feedback can be provided to operation, the monitored patient state facilitating operative doctor real-time and adjustment therapeutic scheme, there is higher practical value.
In the present embodiment, described catheter body comprises body 1 and is arranged on the seal wire (not shown) in body 1, described pressure transducer 3 can be arranged on body 1, also can be arranged on seal wire end, can according to the conduit needing selection different pressures sensor 3 arrangement of operation.
As shown in the figure, described body 1 is also provided with the striped 2 of some scales that makes a check mark, facilitates medical worker to determine the position of conduit.
As shown in the figure, described seal wire is arranged with the screw-casing (not shown) be made up of helical form steel wire, to improve the anti-pressure ability of conduit.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
