Abstract

The utility model relates to a medical chest puncture negative-pressure drainage device used by doctors during pleural puncture effusion in clinic. The utility model is composed of two parts, a drainage pipe (5) and a drainage bag (6) which are made of transparent soft plastic. The side surface of the cylindrical drainage bag (6) is provided with graduation with the unit of 50 ml; the drainage bag (6) is provided with a spring (8); the upper part of the drainage bag (6) is connected with the drainage pipe; a unidirectional exhaust valve (7) is arranged on the drainage bag (6); the lower part of the drainage bag (6) is provided with a liquid discharging valve (9); a puncture needle (1), an injection side hole (2), a flow regulator (3) and a Murphy dropper (4) are arranged on the drainage pipe (2).

Description

Medical Thoracentesis negative pressure drainage device

Technical field:

This utility model belongs to a kind of negative pressure drainage device that uses when putting hydrothorax for doctor's thoracentesis clinically.

Background technology:

Clinically, the row thoracentesis puts hydrothorax or thoracic cavity in that to inject medicine be a kind of aseptic technique, especially some intractable hydrothorax patients that use always, and the hydrothorax amount is more, can not absorb voluntarily, must emit hydrothorax to alleviate patient's misery through thoracentesis.The thoracentesis that is commonly used at present to put hydrothorax clinically is surrounded by following shortcoming: the apparatus that comprises is more, and price is more expensive, has increased the patient burden; Use repeatedly, cause nosocomial infection easily; Need many people to cooperate during use, it is more to take staff, extracts hydrothorax with syringe, and doctor's labor intensity is bigger; The hydrothorax of extracting out can not the direct observation volume amount, could estimate total volume number after must calculating the number of times of extraction, bothers very much, and is also inaccurate; Can not be directly toward the intrathoracic injection medicine.Above shortcoming has determined the thoracentesis bag of present use can not satisfy clinical needs, is badly in need of a kind of easy negative pressure drainage device and puts hydrothorax.

Summary of the invention:

The purpose of this utility model be to provide a kind of safe in utilization clinically, simple to operate, keep that drain is unobstructed, the accurate recording drainage flow, alleviate the disposable thoracentesis negative pressure drainage device of patient's misery.

This utility model is achieved in that it is made up of drainage bag and drainage tube two parts, makes with transparent flexible plastic.Drainage bag is cylindrical, and the side has 50 milliliters and is the scale of unit, built-in spring, can under negative pressure condition drainage bag be unfolded, the top links to each other with drainage tube, enters drainage bag for liquid, design simultaneously has one-way exhaust valve, and bleeding to make by one-way exhaust valve keeps negative pressure state in the drainage bag.There is bleeder valve the below, flows out for liquid.Design has puncture needle, injection side opening, flow regulator, Murphy type burette on the drainage tube.

Advantage of the present utility model is: puncture needle is easy to be fixed in patient's chest, is convenient to keep, and is not subjected to movable restriction; Actuator can effectively be regulated drainage speed, prevents the too fast patient's of the causing discomfort of drainage speed; Murphy type burette is convenient to observe drainage speed; Drainage tube and drainage bag are made with transparent flexible plastic, help observing color, character of drain liquid etc.; Drainage bag is because suction function guarantees that drain is unobstructed; There is the containing mark can the accurate recording drainage flow on the drainage bag; Drain finishes and can directly inject from the injection side opening when injecting medicine in the needs thoracic cavity, needn't go puncture again; Its production cost is low, draws materials conveniently, and the clinical demand amount is big, is convenient to promote, and has potential applicability in clinical practice widely.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Among Fig. 1, the 1st, puncture needle, the 2nd, injection side opening, the 3rd, flow regulator, the 4th, Murphy type burette, the 5th, drainage tube, the 6th, drainage bag, the 7th, one-way exhaust valve, the 8th, spring, the 9th, bleeder valve.

The specific embodiment:

Below in conjunction with accompanying drawing this utility model is described further: at first by one-way exhaust valve (7) the interior air of drainage bag (6) is extracted out before the use, closed flow regulator (3), keep negative pressure state with syringe.Patient gets seat, and the doctor enters the thoracic cavity by the thoracentesis technology with puncture needle (1) puncture, puncture successfully after, open flow regulator (3), spring (8) is unfolded drainage bag (6), under suction function, hydrothorax enters drainage bag (6) by drainage tube (5).Can pass through Murphy type burette (4) in the drain process and observe drainage speed, by flow regulator (3) control drainage speed.Drain finishes, and can directly inject from injection side opening (2) when injecting medicine in the needs thoracic cavity, can open the bleeder valve (9) of drainage bag bottom as the need tapping and emit hydrothorax.
