Description

The continuous power-assisted liquid extracting device of splanchnocoel

Technical field

This utility model relates to a kind of improvement of splanchnocoel pumping device, belongs to medical apparatus and instruments, the continuous power-assisted liquid extracting device of specifically a kind of splanchnocoel.

Technical background

At present, for hydrothorax and seroperitoneum patient, drawing liquid or drainage treatment are carried out in many clinically employing puncture operations.Employed drawing liquid utensil comprises that puncture needle, pumping cylinder, conduit, storage soiling solution bottle constitute, and when operation, earlier to after the site of puncture conventional treatment, the reuse puncture needle thrusts the hydrops lesion, and conduit is connected with Paracentesis needle holder, and the outer end of conduit mouth connects goes up pumping cylinder.Used pumping cylinder generally is the syringe of the conventional big specification of using, the shortcoming of this pumping device: the one, can not continuous sucking, at pleural effusions and ascites more for a long time, sometimes can reach 1000ml, at this moment, repeatedly aspirate, waste time and energy, also bring many miseries to patient; The 2nd, after suction several times, because negative pressure increases in the fluid collection chamber, suction has firmly increased labor intensity; The patent No. is 200420104486.5 abdominal cavity, thoracic cavity liquid extracting device, front end at syringe has added three-way valve, adding the opposite check valve of direction on the conduit mouth that connects puncture needle on the three-way valve with on the conduit mouth that is connected drainage bag, when the piston of syringe is pulled outwardly, hydrops in the splanchnocoel is drawn in the syringe cylinder, when the piston of syringe inwardly pushes away, soiling solution in the injection tube is pushed in the drainage bag, this liquid extracting device, outwell hydrops though need not extract piston, saved the time, suction does not reach gapless connection drawing liquid yet, in addition, the big problem of still unresolved labor intensity.

Summary of the invention

No matter the purpose of this utility model is that piston handle is pulled outwardly or inwardly pushes away if being to provide a kind of, can both realize drawing liquid, and can alleviate the continuous power-assisted liquid extracting device of splanchnocoel of operator's labor intensity.

For reaching above purpose, the technical scheme that this utility model adopted is: the continuous power-assisted liquid extracting device of this splanchnocoel, by puncture needle, depth control shoe, suction catheter, drainage catheter, drainage bag constitutes, suction catheter is " y " shape pipe, connect puncture needle at a port of suction catheter, drainage catheter also is " y " shape pipe, connect drainage bag at a port of drainage catheter, two other port that it is characterized in that suction catheter respectively with left three-way valve on the feed liquor check valve be connected with feed liquor check valve on the right three-way valve, two other port of drainage catheter respectively with left three-way valve on the fluid check valve be connected with fluid check valve on the right three-way valve, between left three-way valve and right three-way valve, be connected left suction cylinder and the right suction cylinder that seat is connected, piston in the suction cylinder of a left side and the piston in the right suction cylinder are separately fixed at the two ends of same piston handle, one side of piston handle is a tooth bar, gear is established at middle part at piston handle, the wheel and rack engagement, when gear clockwise rotates, piston and the piston in the right suction cylinder in the suction cylinder of a left side all promote left, right suction cylinder suction, feed liquor check valve on the right three-way valve is opened, the fluid closed check valve, and the feed liquor closed check valve on the left three-way valve, the fluid check valve is opened, realize right suction cylinder drawing liquid, hydrops in the splanchnocoel enters in the right suction cylinder, left side suction cylinder discharge opeing, soiling solution in the suction cylinder of a left side enters in the drainage bag, when gear rotates counterclockwise, piston and the piston in the right suction cylinder in the suction cylinder of a left side all promote to the right, left side suction cylinder suction, feed liquor check valve on the three-way valve of a left side is opened, hydrops in the splanchnocoel is drawn in the left suction cylinder, fluid closed check valve on the three-way valve of a left side, feed liquor closed check valve on the right three-way valve, the fluid check valve is opened, soiling solution in the right suction cylinder enters in the drainage bag, realizes no gap continuous sucking.This utility model is also implemented by following measure: described left suction cylinder and right suction cylinder all are fixed on the same base plate by corresponding fixedly snap ring, and the axis of left suction cylinder and right suction cylinder is on same straight line; Described gear is fixed on the base plate by fixed bin, turns handle on the turning cylinder outer end of gear is fixing; Described feed liquor check valve, fluid check valve can be made of housing, spring, stifled ball, are prior art, so seldom describe; Described left and right suction cylinder can be changed a social system with syringe; Described drainage bag can be sealed plastic bag, can indicate scale on the bag surface.When using this utility model,, again puncture needle is thrust the hydrops lesion, and control paracentesis depth,, can realize not having gap continuous sucking hydrops with a hands transmitting gear with depth control shoe earlier to the site of puncture conventional treatment.

The beneficial effects of the utility model are: compare with the pleural effusions and ascites aspirator of present use, can accomplish gapless continuous sucking, and by hand mode, so alleviated labor intensity, and easy to operate, health.
