Abstract
The utility model relates to a disposable pneumothorax therapeutic device which belongs to the technical field of a medical appliance. The disposable pneumothorax therapeutic device has the advantages of non cut, little pain and easy operation, and comprises a puncturing needle, a drainage tube and a one-way valve, wherein the puncturing needle is in a hollow structure and is composed of a needle body and a needle handle. The outer diameter of the drainage tube is a bit smaller than the inner diameter of the puncturing needle, and one end of the drainage tube enters a pleural cavity, wherein the end port part is distributed with ventilating small holes communicated with the inner wall of the drainage tube; the other end of the drainage tube is provided with the one-way valve. The disposable pneumothorax therapeutic device used for treating pneumothorax improves a traditional operation method, ensures that a patient who receives therapy has little cut injury and little pain, and greatly reduces the opportunity of subcutaneous emphysema and cross infection. The utility model has simple operation, an operational cut does not need to be sutured, and the utility model can be used both by physicians and surgeons. In addition, the utility model has the advantages of simple structure and convenient use.
Description
Technical field
This utility model relates to a kind of pneumothorax therapeutic apparatus, belongs to technical field of medical instruments.
Background technology
Pneumothorax is because pulmonary lesions or wound cause that the pleural space inner product has a kind of disease of gas.Its cardinal symptom is patient's chest pain, dyspnea etc., and collapse, cyanosis even threat to life can appear in severe patient.The mode that often adopts internal medicine medicine and surgery to bleed for the treatment of pneumothorax clinically.Should adopt surgical operation to bleed immediately for comparatively serious tension pneumothorax, its routine operation mode be: at first need to determine the site of puncture, in patient's ingrtaclavicular part percutaneous incision undertissue, separate Intercostal muscle with the vascular forceps passivity after sterilization anesthesia.Cut off parietal pleura then, the latex exhaustor is inserted in the pleural space, and exhaust hose is fixed on the thoracic wall, make the interior gas of pleural space by deriving in the exhaustor with suture.Aerofluxus is taken out stitches after finishing, skin suture.The whole surgery process needs to be implemented by the surgeon.Because otch is big, cause to the patient big painful, and because kerf and size and exhaust hose may coincide tight to cause gas to overflow into subcutaneous, the formation subcutaneous emphysema.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of non-incision, painful little, easy-operating disposable pneumothorax therapeutic apparatus.
The alleged technical problem of this utility model is solved by following technical scheme:
A kind of disposable pneumothorax therapeutic apparatus, its basic comprising comprises puncture needle, drainage tube and check valve, described puncture needle is a hollow-core construction, form by needle body and needle handle, the external diameter of described drainage tube is slightly less than the internal diameter of puncture needle, it enters the end in the pleural space, and the uniform ventilative aperture that communicates with the drainage tube inwall in its port is provided with a check valve at the other end of drainage tube.
Above-mentioned disposable pneumothorax therapeutic apparatus, the valve body of described check valve are spherical, are respectively equipped with the pipe interface in the relative up and down position of valve body, wherein, the interface of lower end is connected with drainage tube, and described spool is a spheroid, it covers the suitable for reading of pipe interface, between the two for being sealed and matched.
Above-mentioned disposable pneumothorax therapeutic apparatus, the needle body of described puncture needle is a hollow metal tube, the long 30-40 millimeter of needle body, 2.2 millimeters of external diameters, described drainage tube is a polyethylene tube, and ventilative hole diameter is 0.5 millimeter, and drainage tube is marked with scale apart from a segment length that enters the port 30-80 millimeter in the pleural space.
Above-mentioned disposable pneumothorax therapeutic apparatus, described check valve can replace with water-sealed drainage bottle, and the thoracic cavity external port of its drainage tube is inserted among the liquid of water-sealed drainage bottle.
After the treatment pneumothorax adopts this utility model, improve traditional operational approach, made patient's wound damage of receiving treatment little, painful few, and significantly reduced the chance of subcutaneous emphysema and cross infection.Operation technique is simple, and postoperative need not be sewed up wound, and P﹠S all can be implemented.In addition, this utility model simple in structure, easy to use, be easy to promote.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the partial sectional view of puncture needle.
With reference to figure 1, Fig. 2, disposable pneumothorax therapeutic apparatus comprises puncture needle, drainage tube, check valve.Puncture needle is made up of needle body 1 and needle handle 2.Needle body is made by metal material, the long 30-40 millimeter of needle body, and 2.2 millimeters of external diameters, internal diameter 2.0+0.05 millimeter, needle handle can adopt polypropylene material to make, and long 10 millimeters, hollow-core construction, the needle body root embeds among the needle handle.Drainage tube 3 adopts polythene material to make pipe range 800-1000 millimeter, 2 millimeters of externals diameter of pipe, 1.8 millimeters of internal diameters.Drainage tube enters in the pleural space by means of puncture needle by passing in the puncture needle.For preventing that drainage tube from blocking, enter an end of pleural space at drainage tube, in port one 0 mm distance, the ventilative aperture 4 of distribution 4-6 straight-through drainage tube inwall.Be the degree of depth of determining that drainage tube enters pleural space, a segment length that enters the port 30-80 millimeter in the pleural space at the distance drainage tube is marked with scale.The another port of drainage tube is connected with ball valve 5, and check valve is provided with two pipe interfaces 6,7 up and down.12 millimeters of check valve spherical valve body external diameters; 9 millimeters of internal diameters, 3 millimeters of spool bead diameters.Each long 10 millimeters two interfaces, 2 millimeters of internal diameters, the interface 7 that is positioned at the lower end is connected with the thoracic cavity external port of drainage tube.
When using disposable pneumothorax therapeutic apparatus to treat pneumothorax, determine the site of puncture earlier, then puncture needle is thrust in the pleural space, after gas overflows, drainage tube sent into 10-30 millimeter in the pleural space, and from the other end of the drainage tube puncture needle of backing off, port is inserted among the following end interface 7 of check valve, drainage tube is fixed in chest with adhesive plaster.At this moment, the gas in the pleural space is discharged along drainage tube, check valve.Must keep the vertical state of check valve during use, avoid because of check valve tilts, the spool bead departs from valve port and gas is flow backwards.Gas reduces in the thoracic cavity, and pressure can dock syringe after reducing with last end interface 6, extracts residual gas out.Aerofluxus finishes, and extracts drainage tube, and wound need not be sewed up.Described gas eduction unit also can use water-sealed drainage bottle, and with among the liquid in the drainage tube insertion bottle, the mouth of pipe is apart from liquid level 10-20 millimeter during aerofluxus.
