Abstract

The utility model relates to a pericardial effusion puncture positioning guide sleeve. The pericardial effusion puncture positioning guide sleeve is characterized in that a sleeve body is included, a boss is arranged on the side edge of the sleeve body, the boss is provided with at least two parallel guide holes, and the diameters of the guide holes are different from each other. The pericardial effusion puncture positioning guide sleeve has the advantages that three guide holes in the boss on one side of the pericardial effusion puncture positioning guide sleeve enable the needle inserting direction of a puncture needle is consistent with the direction of ultrasonic waves, the fact that the puncture needle can be safely inserted in pericardial effusion is guaranteed, the puncture needle can not be deflected outside the pericardium or inserted in other visceral organs, a doctor can operate conveniently, and the pericardial effusion puncture positioning guide sleeve is disposable so that cross infection can be avoided.

Description

A kind of puncturing pericardial effusion orientation direction cover

Technical field

This utility model relates to a kind of puncturing pericardial effusion orientation direction cover, belongs to medical instruments field.

Background technology

Pericardial effusion is clinical common heart disease crisis, and morbidity is anxious, progress is fast, easily causes the severe complications such as sudden death, therefore needs promptly patient to be done to pericardiocentesis, to save patient's life.Cause pericardial effusion main cause, the one, the transfer of the various tumors such as breast carcinoma, pulmonary carcinoma, lymphoma, the 2nd, after heart intervention treating, surgical operation, cause myocardial rupture hemorrhage, the 3rd, viral, suppurative, Tuberculous etc. infects and produces pericarditis, and the 4th, wound causes hemopericardium.

Pericardiocentesis is that puncture needle is thrust to pericardial cavity, aspirates intrapericardial hydrops, for further diagnosis and treatment.Because heart is ceaselessly being beated; 60-100 beat/min per minute; there is the patient heart rate of pericardial effusion usually over 100 beats/min; the place ahead of heart has lungs to hold; piercing needle is deviation slightly; will cause pneumothorax, hemothorax or directly thrust heart; cause patient to die suddenly; therefore paracentesis pericardii is dangerous technical operation clinically; must just can be completed by the high age and service seniority doctor of heart disease training, this is to diagnosis and treatment has caused and inconvenience, often can later treatment opportunity; to patient, bring more misery, even lost life.

At present, clinical employing two dimensional echocardiogram guides inserting needle and inserts conduit, makes the danger of paracentesis pericardii have certain decline.Before puncture, use localization by ultrasonic paracentesis pericardii point and puncture direction, then remove ultrasonic probe, operation doctor need to keep point of puncture and inserting needle direction firmly in mind, it is identical when during puncture, patient posture, inserting needle direction, point of puncture all should be with localization by ultrasonic, yet in actual mechanical process, patient is because the reasons such as weakness, tachypnea can not keep the same posture long period, there is deviation in the inserting needle direction while making to puncture and position, make this technology produce failed risk, severe patient even jeopardizes patient's life.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of position guiding device that facilitates puncturing pericardial effusion, the direction of inserting needle of making to puncture remains consistent with hyperacoustic direction, guarantee that puncture needle can enter in pericardial effusion safely, and can not be displaced to outside pericardium or enter into other organs.

In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of puncturing pericardial effusion orientation direction cover, it is characterized in that: comprise body, at the side of body, be provided with boss, on boss, have at least two parallel bullports, the diameter of all bullports is different.

Preferably, described bullport has three, and is arranged in parallel according to diameter is descending.

Behind two-dimensional ultrasound location, inserting needle, extracts pericardial effusion quickly and accurately, has very large clinical meaning, for the hospital that there is no heart disease specialist, just can implement paracentesis pericardii, saves patient's life; In the good hospital of clinical condition, the doctor that the age and service seniority is lower, clinical experience is not abundant, also can implement paracentesis pericardii treatment safely at emergency room, and this will reduce difficulty and the risk of pericardiocentesis greatly.

The utility model has the advantages that: it is consistent with hyperacoustic direction that puncturing pericardial effusion orientation direction overlaps three bullports on a side boss make to puncture direction of inserting needle, guarantee that puncture needle can enter in pericardial effusion safely, and can not be displaced to outside pericardium or enter into other organs, facilitate doctor's operation.Cross infection has been avoided in disposable use.

Accompanying drawing explanation

The structural representation that a kind of puncturing pericardial effusion orientation direction that Fig. 1 provides for this utility model overlaps.

The specific embodiment

For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

As shown in Figure 1, a kind of puncturing pericardial effusion orientation direction cover that this utility model provides, comprises body 2, at the side of body 2, is provided with boss 4, has three parallel bullports 5 on boss 4, and all bullports 5 are arranged in parallel according to diameter is descending.

During use, the puncturing pericardial effusion orientation direction cover that this utility model is provided is enclosed within on ultrasound probe, one of operator holds the handle 1 of ultrasonic probe, ultrasonic probe 3 is directly contacted to patient's skin, see the position of puncture on ultrasonic screen clearly, holding position is motionless, the hand-held puncture needle of another hands, along one of three bullports 5, puncture to pericardium, drain hydrops.Depending on pericardial effusion number and viscosity, adopt the puncture needles of different sizes, therefore the diameter of three bullports 5 is large, medium and small.

Claims

1. a puncturing pericardial effusion orientation direction cover, it is characterized in that: comprise body (2), side at body (2) is provided with boss (4), has at least two parallel bullports (5) on boss (4), and the diameter of all bullports (5) is different.

2. a kind of puncturing pericardial effusion orientation direction cover as claimed in claim 1, is characterized in that: described bullport (5) has three, and is arranged in parallel according to diameter is descending.
