Abstract
This utility model discloses a kind of pressure transducer of auto-flushing, comprises main body, is arranged on pressure measurement pipeline in main body, is arranged at the valve mechanism of pressure measurement pipeline, and described valve mechanism is provided with the electrical autocontrol valve that interval is opened, closed at preset timed intervals.Pressure transducer that can auto-flushing of the present utility model, owing on the pressure measurement pipeline in main body, valve mechanism being set, the electrical autocontrol valve that valve mechanism is provided with on schedule and opens, closes, therefore can guarantee flushing liquor timing, rinse pressure measurement pipeline quantitatively, to prevent line clogging.Use the pressure transducer of auto-flushing of the present utility model, almost can avoid the blockage problem of pressure measurement pipeline completely, guarantee that pressure measurement pipeline is unobstructed, guarantee seriality and the accuracy of monitoring; By alleviating medical worker's burden, without artificial flushing, medical worker can concentrate one's energy to process patient more simultaneously.
Description
Technical field
This utility model relates to a kind of medical auxiliary equipment technical field, relates in particular to a kind of pressure transducer of auto-flushing.
Background technology
Arterypuncture pressure measurement is a kind of monitoring of blood pressure method that has wound, can directly reflect in time the situation of change of blood pressure, can repeatedly extract blood specimen and carry out blood gas analysis simultaneously.Monitor therapy for major operation, medium operation bigger than normal and critical patient is significant.Therefore be widely used in Anesthesia Department and Intensive care treatment.
Arterypuncture pressure measurement is that needle of retaining on artery is directly punctured and inserts intra-arterial (conventional radial artery), and then indwelling needle is connected with pressure transducer, and transducer is connected on monitor.By transducer, pressure signal is converted to the signal of telecommunication, the screen of monitor will show red artery waveform and blood pressure values (comprising systolic pressure, diastolic pressure, mean pressure).Because arterial puncture detaining needle needs to keep somewhere relatively for a long time in intra-arterial, therefore must use saline or heparin saline repeatedly to rinse, otherwise in indwelling needle, will there will be blood clot, light affect the accuracy of pressure measurement, heavy stop up remaining needle and cannot pressure measurement.Needs based on rinsing, on current pressure transducer with flusher, but be all artificial flusher, and in clinical position, due to medical worker's work load weight, be busy with dealing with various work, usually can not to tremulous pulse, rinse on time, tend to cause above-mentioned clogging, make troubles to clinical monitoring and treatment work, and patient is produced to harmful effect.
As can be seen here, how to provide a kind of pressure transducer of auto-flushing, can automatically rinse and without medical worker's manual operation, the phenomenon that avoids clogging, this is the current technical issues that need to address in this area.
Utility model content
The purpose of this utility model is, a kind of auto-flushing pressure transducer is provided, and can automatically rinse and without medical worker's manual operation, phenomenon avoids clogging.
For solving above technical problem, the technical solution of the utility model is:
A pressure transducer for auto-flushing, comprises main body, is arranged on pressure measurement pipeline in described main body, is arranged at the valve mechanism of described pressure measurement pipeline, and described valve mechanism is provided with the electrical autocontrol valve that interval is opened, closed at preset timed intervals.
Preferably, described electrical autocontrol valve comprises input control end, microprocessor, electromagnetic valve, timer, described input control end sends last valve closing and valve is opened automatically next time time interval parameter a, valve opening time parameter b to described microprocessor, and described microprocessor coordinates with timer by parameter a and parameter b startup electromagnetic valve.
Preferably, in described main body, connect an attaching plug.
Preferably, described valve mechanism is also provided with manually-operated gate.
Compared with prior art, the pressure transducer of auto-flushing of the present utility model, owing on the pressure measurement pipeline in main body, valve mechanism being set, the electrical autocontrol valve that valve mechanism is provided with on schedule and opens, closes, therefore can guarantee flushing liquor timing, rinse pressure measurement pipeline quantitatively, to prevent line clogging.Use pressure transducer that can auto-flushing of the present utility model, almost can avoid the blockage problem of pressure measurement pipeline completely, guarantee that pressure measurement pipeline is unobstructed, guarantee seriality and the accuracy of monitoring; By alleviating medical worker's burden, without artificial flushing, medical worker can concentrate one's energy to process patient more simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pressure transducer preferred embodiment of this utility model auto-flushing;
Fig. 2 is the schematic diagram of electrical autocontrol valve in Fig. 1.
The specific embodiment
For making the technical solution of the utility model clearer, below in conjunction with accompanying drawing, by specific embodiment, this utility model is elaborated.
As shown in Fig. 1～Fig. 2, the auto-flushing pressure transducer of the present embodiment comprises main body 1, attaching plug 11, power line 12, inlet 13; Valve mechanism 14; Measuring pressure passage 15, liquid outlet 16.
Described valve mechanism 14 comprises manually-operated gate and electrical autocontrol valve, and electrical autocontrol valve comprises input control end, microprocessor, electromagnetic valve, timer.Wherein, two parameter a of input control end output and b are to microprocessor, and wherein a parameter is the interval of last valve closing and the automatic unlatching of valve next time; B parameter is valve opening time; Microprocessor, according to a, b parameter, under the synergism of timer, starts electromagnetic valve by time parameter a, b, open electrical autocontrol valve interval and fix, and the time of valve opening is fixed.Because the pressure of liquid is substantially constant, thus at every turn basic identical by the amount of liquid of valve, so just realize flushing liquor and rinse regularly, quantitatively pressure measurement pipeline.
Wherein, the structure of main body 1 is same as the prior art, repeats no more herein.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, within not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
