Above-mentioned gage probe can be can measuring vessel in the pick off of working solution weight or volume.
Feed liquor pipeline between an above-mentioned pump and the suction pump high pressure chest is provided with pressure transducer No. one, and the fluid pipeline between suction pump low-pressure cavity and No. two pumps is provided with pressure transducer No. two; One, No. two pressure transducers connect above-mentioned central controller.
When the hematoma clearance device starts, at first obtain the initial variable of working solution in one, No. two container simultaneously through one, No. two gage probe by central controller, be set at a0 and b0 respectively, and control a pump and No. two pumps bring into operation; Obtain the variable of working solution in one, No. two container by central controller in real time through one, No. two gage probe subsequently, be set at a1 and b1 respectively, and relatively obtain changing value, be set at Δ a and Δ b respectively with each self-corresponding above-mentioned initial variable; Central controller adjusts accordingly a pump and the pump liquid measure of No. two pumps in the unit interval through comparing Δ a and Δ b value.
The present invention has following useful technique effect:
Among the present invention; The twin formula balance lavage apparatus of being taked; By the variable of central controller according to working solution in two containers that obtain simultaneously; Adjust the running status and the work efficiency of two pumps, be enough to satisfy the requirement of accomplishing surgical tasks such as intracranial hematoma, can overcome existing operation of existing hematoma clearance device and the high defective of maintenance cost.In addition, also be beneficial to direct discovery active hemorrhage etc.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is illustrated further:
Figure is the structural principle sketch map of one embodiment of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of hematoma clearance device comprises suction pump 1 and the twin formula balance lavage apparatus that links to each other with suction pump.Above-mentioned suction pump comprises high pressure chest and low-pressure cavity.Above-mentioned twin formula balance lavage apparatus comprises feed liquor pipeline 2, fluid pipeline 3, pump 4, No. two pumps 5, a container 6 and No. two containers 7.An above-mentioned container is through the high pressure chest of a feed liquor pipeline and a pump connection suction pump, and the low-pressure cavity of suction pump connects No. two containers through fluid pipeline and No. two pumps.An above-mentioned container disposes 8, No. two containers of a gage probe and disposes gage probe 9 No. two; Each gage probe can select for use can measuring vessel in the pick off of working solution weight or volume.An above-mentioned pump and No. two pumps dispose 10, numbers gage probes of central controller that can control each pump operation state and are connected central controller with No. two gage probes.
In aforesaid way, also can an above-mentioned pump and the suction pump high pressure chest between the feed liquor pipeline be provided with pressure transducer 11 No. one, the fluid pipeline between suction pump low-pressure cavity and No. two pumps is provided with pressure transducer 12 No. two; One, No. two pressure transducers connect above-mentioned central controller.Dynamic monitoring when being used for the working solution operation.
Operation principle of the present invention and mode can be roughly following:
When the hematoma clearance device starts, at first obtain the initial variable of working solution in one, No. two container simultaneously through one, No. two gage probe by central controller, be set at a0 and b0 respectively, and control a pump and No. two pumps bring into operation; Obtain the variable of working solution in one, No. two container subsequently in real time through one, No. two gage probe by central controller; Be set at a1 and b1 respectively, and relatively obtain changing value, be set at Δ a and Δ b respectively with each self-corresponding above-mentioned initial variable; That is: Δ a=a1-a0, Δ b=b1-b0.For guarantor unit is got into the working solution liquid measure as much of hematoma and discharge by suction pump in the time, above-mentioned Δ a and Δ b should equate (together) in theory, in practical operation are the two difference to be controlled in the set point get final product.Central controller adjusts accordingly a pump and the pump liquid measure (work efficiency) of No. two pumps in the unit interval through comparing Δ a and Δ b value.If Δ a and the Δ b difference between the two is in set point then continue the work efficiency of current two pumps (station); If Δ a exceeds set point greater than Δ b and difference, the work efficiency of then controlling a pump (station) is lower than the work efficiency of No. two pumps (station); Vice versa.
