Compared with the prior art, the pressure-measuring drainage catheter is simple in structure and low in cost, the pressure-measuring tube is always in a smooth state, the intracranial pressure (ICP) can be sensitively shown, and the measurement is accurate.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to pressure measurement drainage catheter that in a kind of body fluid drain and body, piezometry, particularly intracranial pressure (ICP) measure and pressure testing method thereof.
Background technology
China is craniocerebral trauma and cerebral hemorrhage big country occurred frequently, annual operation of opening cranium amount the first in the world, Craniotomy each time, placing drainage 1 ~ 4.The change of illness state reflection that intracranial pressure (ICP) measures for Cerebral Injury patient is accurate, responsive, in many ways recommended to adopt, but it is expensive to be limited to equipment, high-value consumables and maintenance expense, more difficult universal.Now use ventricular drainage tube, as one of ICP observation approach, from liquid height and fluctuation situation, ICP can be judged when it is unobstructed, but when drainage-fluid is discharged unstable, too high cranium pressure presses off the ventricles of the brain, when pipe is obstructed, then loses pressure measurement effect.
Summary of the invention
For solving the above-mentioned defect that prior art exists, the object of the present invention is to provide a kind of structure simple, there will not be blocking, pressure-measuring pipe is in unobstructed state all the time, sensitive reflection ICP, measures accurate pressure measurement drainage catheter.
Another object of the present invention is to provide a kind of pressure measurement drainage catheter pressure testing method.
For achieving the above object, the technical solution used in the present invention: this pressure measurement drainage catheter has drainage tube main body, it is characterized in that: the end side side wall of described drainage tube main body is provided with alcove, the opening part of described alcove is provided with inelastic sealing film, described sealing film is loose thin film and forms airtight pressure measurement blister cavities with alcove, described pressure measurement blister cavities is communicated with topping up tubule and pressure measurement tubule, described topping up tubule and pressure measurement tubule are drawn in drainage tube main wall, the port of export of described pressure measurement tubule connects on pressure measurement scale or electronic pressare-measuring instrument, the port of described topping up tubule connects topping up joint.
Described topping up joint is the joint that can coordinate with injector head, and joint is connected with seal plug.
Described sealing film is high molecula resin film.
Described drainage tube main body is silica gel drainage tube.
Described pressure measurement blister cavities can hold 4ml liquid or gas.
A kind of pressure measurement drainage catheter pressure testing method, is characterized in that operating in the steps below:
(1) in pressure measurement blister cavities, inject liquid through topping up tubule by topping up joint, be full of pressure measurement blister cavities and continue fluid injection, the residual gas in pressure measurement blister cavities and pressure measurement tubule is discharged, ensure to be full of liquid in pressure measurement blister cavities and pressure measurement tubule;
(2) impose pressed by external force pressure measurement blister cavities or from the reverse pumping liquid of topping up joint, make pressure measurement blister cavities be half expanded state, topping up tab closure, the parallel pressure measurement scale of pressure measurement tubule, perpendicular to horizontal plane, and make open-ended in air, by level gauge at zero point, pressure measurement scale is located in upright position;
(3) half full pressure measurement blister cavities is inserted in brain in operation with drainage tube main body, and after closing cranium, and pressure measurement blister cavities is to the discharge opeing of pressure measurement tubule under ICP effect, and liquid level rising, arranging on the basis that pressure measurement zero point of scale parallels with the ventricles of the brain, pressure measurement starts.
Adopt the beneficial effect of technique scheme: the Packed pressure measurement blister cavities of this pressure measurement drainage catheter tool, partly liquid is filled with in pressure measurement blister cavities, this pressure measurement blister cavities is communicated with pressure measurement scale or electronic pressare-measuring instrument (when connecting electronic pressare-measuring instrument, pressure measurement capsule pipe is inflatable) by pressure measurement tubule.Because pressure measurement tubule communicates with pressure measurement blister cavities is airtight, and with brain inside and outside isolated, only end and large gas-liquid equilibrium, liquid can not pollute intracranial, wound inner blood, tissue can not enter pressure measurement blister cavities and pressure measurement tubule, therefore there will not be the phenomenon of blocking pressure measurement tubule, pressure measurement tubule is in unobstructed state all the time, sensitive reflection ICP.This pressure measurement drainage catheter puts into brain at the end of operation, need not perform the operation separately and put pipe, not increase wound and operating time.Under the simple and easy pressure measurement mode of pressure measurement scale, need medical worker's timing to observe liquid level and reading, be recorded on specific record table, and in time within 12 ~ 24 hours, summing up, each point be wired to the ICP curve of cyclical fluctuations, deposit in case history.And under the mode connecting electronic pressare-measuring instrument, machine can automatic record.Compared with prior art, structure is simple, and with low cost, pressure-measuring pipe is in unobstructed state all the time, sensitive reflection ICP, measures accurately.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail.
Fig. 1 is structural representation of the present invention.
