Abstract

The utility model relates to a pneumothorax puncture needle, particularly a disposable pneumothorax puncture drainage device. A puncture needle of the utility model forms an interspaceal fit with a jacket tube. The front end of the puncture needle forms a sharp pyramid or a cone which are protruded beyond a small hole at the front end of the jacket tube. The back end of the jacket tube is provided with a joint. One end of the joint is connected with the jacket tube, and the other end is connected with a drainage tube. When the puncture needle is inserted into a thoracic cavity together with the jacket tube by dropped through sense, the puncture needle is extracted immediately. The depth is adjusted through the jacket tube. A positioning plate is used for determining the depth of the jacket tube. The utility model can effectively prevent malignant medical negligence. The utility model is a safe and convenient medical puncture needle.

Description

Disposable thoracic drainage and thoracentesis device

This utility model relates to a kind of thoracentesis needle set, particularly a kind of safe in utilization, convenient, healthy disposable thoracic drainage and thoracentesis device.

Thoracentesis is common clinical treatment method.Thoracentesis in the past is to utilize the draw point of different model directly to carry out.The draw point head is sharp sharp, and in piercing process, the doctor is inserted into the hydrops position with the sense that falls through with draw point.In the drawing liquid process, all may make the needle point of draw point stab lung tissue because the propelling of draw point or lung tissue are breathed, its consequence is serious, so, according to clinical experience for many years, the malpractice of thoracentesis is owing to puncture needle or the misoperation used cause.

The purpose of this utility model will provide a kind of disposable thoracic drainage and thoracentesis device exactly, when being punctured to the hydrops degree of depth, only making sleeve pipe place hydrops, and carries out drain with drainage tube, for puncture for treating provides Centesis instrument safe in utilization.

For achieving the above object.This utility model is taked following technical scheme: disposable thoracic drainage and thoracentesis device comprises sleeve pipe, puncture needle, drainage tube, joint, location-plate.The sharp end of puncture needle is pyramid or cone.Pyramid helps otch, and cone is beneficial to processing.On telescopic tube wall, have through hole especially for the ease of imbibition.The sleeve pipe front end contracts aperture less than casing inner diameter, and the sharp end of puncture needle is partly outside the aperture of outstanding sleeve pipe front end.A joint is installed in the sleeve pipe rear end, joint one end and sleeve pipe radial fit, and end is connected with the drainage tube radial fit in addition, and puncture needle is by joint and cover pipe orifice matched in clearance.In order on casing wall, to be processed with the scale that shows paracentesis depth for the doctor points out paracentesis depth and location external, behind the puncture certain depth, utilize strile gauze dressing that location-plate is fixed on the sleeve pipe, with strile gauze dressing location-plate is fixed on the human body surface simultaneously.The endoporus of location-plate cooperates with the cover external diameter of pipe, and this cooperation should be matched in clearance.When puncture, at first with puncture needle by joint and cover pipe orifice matched in clearance, the sharp end of puncture needle is partly given prominence to outside pipe front end aperture, want the top layer, site of puncture to cut an osculum in desire again, puncture needle inserts the hydrothorax position together with sleeve pipe, extracts puncture needle, only stay sleeve pipe at the hydrops position, drainage tube is connected with joint, and hydrops just can enter drainage tube along sleeve pipe, excretes thereupon.

The utlity model has following advantage:

1, has certain safety, after sleeve pipe being inserted certain depth with the sense that falls through, take out puncture needle immediately, only utilize sleeve pipe and drainage tube to carry out discharge opeing, this moment, no matter tubing depth changed or the lung tissue breathing, can not stab lung tissue,, can not cause the generation of pernicious malpractice because the sleeve pipe front end is coniform.

2, has the depth cue positioning function.After inserting certain depth with the sense that falls through, the degree of depth on the casing wall gives the doctor with depth cue, take out puncture needle after, the doctor is adjustable depth still, utilizes location-plate that sleeve pipe is fixed then.

3, this utility model is not only applicable to liquid breast, empyema, is applicable to pneumothorax yet.Before puncture, pre-otch is littler than conventional incision.

4, this utility model is simple in structure, with low cost, in order to prevent cross infection, can take disposable occupation mode.

Below in conjunction with accompanying drawing this utility model is described further.

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

With reference to Fig. 1.The disposable thoracic drainage and thoracentesis device that this is made up of sleeve pipe (2), puncture needle (5), drainage tube (8), joint (6), location-plate (1).The all available non-toxic plastic of puncture needle, sleeve pipe, joint, location-plate and drainage tube is made, and also available metal is made.Puncture needle (5) is by joint endoporus and cover pipe orifice matched in clearance, and its front end is pyramid (4) or is cone.The front end of sleeve pipe (2) shrinks an aperture gradually, and its hole is less than casing inner diameter, and the sharp end of puncture needle (5) is partly given prominence to outside the aperture of sleeve pipe front end.For the ease of gas, liquid or the pus of drain different depth, the different depth at tube wall has several through holes (3) especially.

For the ease of connecting, installing, especially in the erection joint of sleeve pipe rear end (6), joint one end is connected with the sleeve pipe radial fit, and end is connected with drainage tube (8) radial fit in addition.

The endoporus of location-plate (1) cooperates with the cover external diameter of pipe, is processed with the scale that shows paracentesis depth on sleeve outer wall.

(7) are handle among the figure.

In use, at first cut an osculum in advance at desire skin puncture place, thrust in the lump in hydrops (gas) chest together with sleeve pipe then, after the sense that falls through is arranged, transfer to puncture needle (5) immediately, sleeve pipe (2) is stayed in the thoracic cavity, if the degree of depth is not enough, still can continue deeply can not stab lung tissue like this, till appropriate depth.Connect drainage tube (8), stationary positioned plate (1) and can reach the ejectment of thoracic cavity gas, liquid, pus.
