Description

The pericardiocentesis drainage device

This utility model belongs to a kind of medical apparatus and instruments, is specifically related to a kind of tap utensil of pericardial effusion.

Puncturing pericardial effusion tapping in the past is to be enclosed within on the rubber tube with injecting needle base, clamps rubber tube with mosquito forceps, puncture successfully after, syringe jacket on the rubber tube of needle stand, is loosened the mosquito forceps on the rubber tube, extract liquid.Done following deficiency like this: at first because pericardial effusion single step of releasing liquid measure can not surpass setting, thus the paracentesis pericardii tapping of having to carry out repeatedly, thus dangerous and nosocomial infection chance increased, also increased patient's economy and psychological burden simultaneously.Must the assistant help when next is puncture, clamp syringe needle with mosquito forceps and fix, this fixing very unstable, cause the tap failure easily, even pernicious malpractice takes place.Moreover artificial drawing liquid flow velocity is inhomogeneous, and the blood circulation symptom takes place in too fast meeting.In addition, the syringe that drawing liquid is used is less, needs to take off discharge opeing repeatedly from rubber tube repeatedly, and not only operation inconvenience also increases medical sexuality and dyes chance.Same piece of puncture needle uses on one's body repeatedly different patients, also increased the cross infection chance.And the mobile medical treatment of going to the countryside, the consultation of doctors of going out are carried all inconvenient.

The purpose of this utility model provides a kind of paracentesis pericardii, fixed, controlled tapping speed easily avoided repeatedly, can avoid cross infection and infectious disease transmission, pericardiocentesis drainage device easy to carry again.

Technical solutions of the utility model are as follows: a kind of pericardiocentesis drainage device, it is characterized in that forming jointly by puncture part and drain part, and wherein puncture part comprises puncture needle and soft tube, the puncture needle rear portion is transparent needle stand, and is plugged with stopper; Silicon case casing is outside puncture needle, and the soft tube back seat at its rear portion can be connected with the drainage tube joint of drain part; Drain partly comprises drainage tube and Liquid storage bag, and drainage tube is connected in sequence by joint, rubber tube and flexible rubber hose, also is provided with speed regulator on drainage tube; The Liquid storage bag front end links to each other with drainage tube, and afterbody is provided with leakage fluid dram, and pkt. flap is housed.

But the continuous tapping of this utility model one-time puncture, flow velocity is adjustable also can to close extremely, dependable performance, safety and sanitation, a people gets final product complete operation, and easy to carry, the consultation of doctors, the mobile medical treatment of going to the countryside can be used for going out, the place of especially poor outlying, shortage of medical services and medicines, it can reduce patient's economy and psychological burden, reduces patient's misery.

Be described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of an embodiment of this utility model.

In the embodiment shown in fig. 1, the pericardiocentesis drainage device is made of parts such as puncture needle (1), soft tube (2), drainage tube joint (6), rubber tube (7), flexible rubber hose (10) and Liquid storage bags (11), after puncture needle (1) inserts pericardium together with soft tube (2) with the sense that falls through, visible liquid flows out in the transparent needle stand (4) at puncture needle rear portion, pull out the stopper (5) on the needle stand, available syringe pump small amount of liquid is inspected by ready samples immediately, to determine hydrops character and cause of disease.When suppurative hydrops or hydrops have pericardial tamponade, sustainable, can control flow velocity and put pus, tapping automatically with relief of symptoms.Extract puncture needle (1), soft tube (2) is stayed in the pericardium, be exposed at external soft tube and be fixed on patient's thoracic wall with adhesive operation towel, soft tube back seat (3) is connected with drainage device joint (6).For making drain smooth and easy, have side opening on the anterior tube wall of soft tube (2).Pinch rubber tube (7) with hands and can make and produce negative pressure in the pipeline of the place ahead, whether unimpeded and prevent line clogging to understand pipeline.The flap valve that is provided with on the drainage tube (8) can prevent that liquid from flowing backwards.On drainage device, also be provided with speed regulator (9), the small wheels on the speed regulator is promoted to oppress flexible rubber hose (10) forward, thereby the control flow velocity also can close dead fully.Control this utility model drainage device slowly continues tapping, can break through traditional tapping setting.The Liquid storage bag that links to each other with drainage tube is printed on capacity marking on (11), and the Liquid storage bag afterbody is provided with the leakage fluid dram (12) that the ebonite pipe is made, and unclamps pkt. flap (13) and hydrops can be emitted.Whole drainage device tubing sealing can prevent that pathogen from entering human body by drainage device.In the drainage device is normal atmosphere, is malleation in the pericardium during pericardial effusion, can utilize this pressure differential and Liquid storage bag position to be lower than the pressure difference that cardiac position produces, and pericardial effusion is automatically drained in the Liquid storage bag.

This utility model pericardiocentesis drainage device adopts disposable airtight sterilization wrap, and unpacking can be used.Soft tube wherein can be with the good non-toxic polyethylene plastic production of tissue compatible.

Claims (3)
