Description

Continuous sucking bushing type pericardiocentesis drainage device

Technical field

This utility model relates to a kind of improvement of pericardiocentesis drainage medical apparatus and instruments, and specifically a kind of continuous sucking bushing type pericardiocentesis drainage device is applicable to pericardial effusion patient's pericardiocentesis drainage.

Background technology

Clinical the pericardial effusion patient is generally adopted the pericardiocentesis drainage art, hydrops is drawn, intrinsic pressure to alleviate.Used utensil comprises that utensils such as puncture needle, drainage catheter, mosquito forceps, drawing liquid syringe constitute in drain at present, when pericardiocentesis drainage, behind conventional treatment skin, thrust pericardial cavity with puncture needle earlier, the reuse drainage catheter is connected with the Paracentesis needle holder end, clamp drainage catheter earlier with mosquito forceps, to prevent the air admission pericardium, drawing liquid syringe on the drainage catheter outer termination unclamps the mosquito forceps on the drainage catheter then again, the piston handle of pulling drawing liquid syringe can carry out drawing liquid.If need to extract the volume hydrops, need to close with mosquito forceps repeatedly and unclamp drainage catheter.The shortcoming of this drainage apparatus is: used utensil is scattered, uses inconvenience, and operation is wasted time and energy; The patient more for pericardial effusion need repeatedly puncture, and drawing liquid speed is intermittent big, and wayward, and drain thoroughly also can not increase the chance of pericardiosymphysis.

Summary of the invention

The purpose of this utility model is to provide that a kind of structural integrity is strong, easy to operate, safe in utilization, drawing liquid is continuous and speed is controlled easily, need not the continuous sucking bushing type pericardiocentesis drainage device of repeated localised puncture for the many persons of pericardial effusion amount.

For reaching above purpose, the technical scheme that this utility model adopted is: this continuous sucking bushing type pericardiocentesis drainage device, comprise puncture needle, the silica gel sleeve pipe, drainage catheter, drainage bag constitutes, it is characterized in that being provided with the sealing plug in the telescopic seat of silica gel port part, on the telescopic sidewall of silica gel, establish the drainage catheter union joint, one of drainage catheter terminates on the drainage catheter union joint, the other end of drainage catheter is divided into two, and be connected with corresponding drawing liquid check valve on the continuous sucking device respectively, the discharge opeing check valve of continuous sucking device is communicated with drainage bag by discharging tube, puncture needle passes the sealing plug and injects in the silica gel sleeve pipe, and makes needle point expose the telescopic oral area of silica gel.This utility model is also implemented by following measure: described sealing plug is made of lid, circular film and ring spring, circular film is located in the wall of lid, periphery at circular film is provided with ring spring, to strengthen the sealing property of sealing plug, after puncture needle is extracted, be enough to guarantee sealing, liquid is not revealed in not air inlet; Described continuous sucking device, constitute by packed-piston tube, piston, piston rod and corresponding drawing liquid check valve and discharge opeing check valve, the drawing liquid check valve is connected with drainage catheter, the discharge opeing check valve is connected with discharging tube, when the pulling piston, the drawing liquid check valve of piston nose is opened, and pericardial effusion can be drawn in the packed-piston tube of piston nose, the discharge opeing check valve of piston rear end is opened, and the interior liquid of packed-piston tube of piston rear end is discharged; When promoting piston, the drawing liquid check valve of piston rear end is opened, and in the piston cylinder of pericardial effusion suction piston rear end, the discharge opeing check valve of piston nose is opened, and the liquid in the piston cylinder of piston nose is discharged, and is reciprocal successively, realizes continuous sucking.During use, under the B ultrasonic guiding, puncture needle is thrust the pericardial effusion chamber, use the syringe that links to each other with the puncture needle needle stand to extract the pericardium intracavity liquid out after, showing punctures puts in place, can extract puncture needle, the silica gel sleeve pipe is kept somewhere, the telescopic seat of silica gel port part under the effect of sealing plug, automatic sealing, can directly withdraw from puncture needle like this, carry out continuous drawing.

The beneficial effects of the utility model are: compare with the paracentesis pericardii utensil of present use, structural integrity is good, and is easy to operate, but one-time puncture, the continuous sucking drain damages for a short time, and drainage speed is arbitrarily controlled, and is safe in utilization.
