Abstract

The utility model provides a medical improved thorax remaining needle which is provided with a flexible catheter, a stylet and a drainage bag connected with a catheter and is characterized in that the rear tail end of the flexible catheter is arranged at a connector base which is hollow and is provided with an outside thread; the stylet is longer than the flexible catheter, and the rear end of the stylet is connected with a syringe; the tail end of the catheter is connected to a connector with an inside thread which can be screwed with the outside thread of the connector base. The utility model has the advantages that the operation step is simplified and the complex operation of guide wire posting is avoided; because the flexible catheter does not need to run in blood vessel, so the requirement for material of the flexible catheter is reduced and the cost is reduced; and side holes on the side wall at the front end of the flexible catheter can increase drainage passage at the front end so as to facilitate the drainage.

Description

Internal medicine Improvement type chest cavity indwelling pin

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of pleural cavity closed drainage device of specializing in the clinical use of internal medicine.

Background technology

At present in internal medicine clinically at hydrothorax patient's hydrothorax drain, hydrothorax diagnosis, thoracic cavity medicine injection treatment, generally take two kinds of means: a kind of is direct puncture, also promptly directly thrust in the thoracic cavity after the proper site with puncture needle, puncture needle external body tap is established syringe, the manual hydrops that extracts, this method wastes time and energy, and can not keep somewhere, and needs repeatedly repeated localised puncture; Another kind is to adopt dark venous duct puncture to insert thoracic cavity and drain, this method needs earlier seal wire to be inserted the thoracic cavity, relying on seal wire again is that the path pushes dark venous duct up to arriving proper site, on external dark venous duct, connect the drainage bag of establishing with the urinal improvement then, this method complex operation, and owing to former dark venous duct need be walked in blood vessel, so the material capability to dark venous duct is had relatively high expectations, promptly require dark venous duct to have the anticoagulant effect, have the flexibility of in blood vessel, walking, thereby improved cost.

Summary of the invention

This utility model provides a kind of internal medicine Improvement type chest cavity indwelling pin, and purpose is to solve the prior art problem, provides a kind of practical and convenient, the apparatus that is used for drain pleural effusion that cost is low.

This utility model technical scheme that adopts of dealing with problems is:

A kind of internal medicine Improvement type chest cavity indwelling pin has a flexible conduit, it is characterized in that: the back end of flexible conduit is arranged in a hollow and has externally threaded interface pedestal; Also have a nook closing member, nook closing member length is greater than flexible conduit length, and the nook closing member rear end is equipped with syringe; Also have a drainage bag that is equipped with conduit, described catheter tip is arranged in joint for fittings with internal threads, the female thread of this joint can with the external thread spiro fastening of above-mentioned interface pedestal.

Flexible conduit be hollow structure.

The front end side wall of flexible conduit has more than one side opening.

The interface block intracoelomic cavity is taper, the syringe front end be can be chimeric with the interface block intracoelomic cavity taper, nook closing member is arranged in the syringe front end.

The back segment of flexible conduit is folded with pipe clamp.

The beneficial effects of the utility model: flexible conduit can be set in outside the nook closing member, utilize syringe and nook closing member that flexible conduit is punctured in the thoracic cavity, extract nook closing member again out, one section of flexible conduit is kept somewhere in body, the remainder of flexible conduit is positioned at the joint that interface pedestal terminal behind external and the flexible conduit can be arranged in drainage bag, can drain, thus operating procedure simplified, avoided seal wire to insert the troublesome operation of method; Terminal interface can be connected with test tube and makes things convenient for the clinician to send the hydrothorax specimen behind the flexible conduit; Because flexible conduit need not walked in blood vessel, therefore the material to flexible conduit requires to reduce, thereby has reduced cost; The side opening of the front end side wall of flexible conduit can increase the drainage channel of front end and make things convenient for drain.

The specific embodiment

The utility model is described in further detail below in conjunction with specific embodiment.

As shown in Figure 1, the internal medicine Improvement type chest cavity indwelling needle set of present embodiment has a flexible conduit 1, and this flexible conduit 1 is the drainage tube of hollow structure.When nook closing member was inserted conduit, whole conduit had just had certain rigidity, helped to wear out skin, and the back end of flexible conduit 1 fixedly is arranged in a hollow and has externally threaded interface pedestal 2, and interface pedestal 2 inner chambers are taper.The back segment of flexible conduit 1 is folded with pipe clamp 3.

As shown in Figure 6, the front end side wall of flexible conduit 1 also has several side openings 11.

As shown in Figure 2, present embodiment also has a nook closing member 4, and nook closing member 4 length are slightly larger than flexible conduit 1 length, and nook closing member 4 rear ends are equipped with syringe 52, syringe front end 51 be can with the chimeric taper of interface pedestal 2 inner chambers.Nook closing member is inserted before puncture in the flexible conduit in the present embodiment, for flexible conduit provides rigidity, helps through thoracentesis, and when syringe was used for judging puncture, whether syringe needle had entered the thoracic cavity.

As shown in Figure 3, present embodiment also has a drainage bag 6 that is equipped with conduit 61, and described conduit 61 ends are arranged in joint for fittings with internal threads 7, the female thread of this joint 7 can with the external thread spiro fastening of above-mentioned interface pedestal 2.

During use, be illustrated in figure 4 as the preceding state of thoracentesis, earlier nook closing member 4 is inserted in the flexible conduit 1, conical internal cavity behind the nook closing member 4 for the syringe front end 51 chimeric incoming interface pedestals 2 of taper, and nook closing member 4 leading sections stretch out before flexible conduit 1, are integrated with flexible conduit 1, form a puncture needle, when nook closing member 4 was inserted flexible conduit 1, whole flexible conduit 1 had just had certain rigidity, helped to wear out skin.Syringe 52 pumpbacks during puncture judge whether the thoracic cavity has arrived thoracic cavity (pumpback to hydrothorax time represent that the syringe needle of nook closing member 4 has arrived the thoracic cavity), and it is dark to avoid puncturing, and wears and cardiopulmonary.

After being punctured to proper site, nook closing member 4 is extracted out from flexible conduit 1, Figure 5 shows that puncture for another example after, extract nook closing member, the conduit state that stays in the body is located at joint 7 spiral shells on the interface pedestal 2, unclamps pipe clamp 3, just drain pleural effusion can be arrived in the drainage bag 6.Clamp pipe clamp 3, can change drainage bag 6.
