The liquid discharge end of the liquid discharge is connected into a drainage bottle, so that the syringe can be prevented from repeatedly replaced, the operation is simple, and the use is safe and reliable.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of improvement of surgical instrument, is a kind of multi-functional thoracentesis device specifically.
Background technology
Pleurocentesis is usually used in the thoracic cavity is carried out aerofluxus, checked the character of hydrothorax by extracting hydrothorax, or intrapleural injection etc., be clinical diagnosis and treatment technology commonly used.
At present, the following method of the normal employing of thoracentesis operation:
Thoracic-puncture needle adopts 18～19G puncture needle, and its pin stalk is about 70mm, and internal diameter is that an end of the blood transfusion latex tubing of 4mm connects puncture needle, and the other end connects syringe.In clinical practice, often will exchange syringe in the tapping process repeatedly for several times, and its pin stalk is oversize, puncture that successfully the back is difficult fixes, in the drawing liquid process, easily cause needle point in the thoracic cavity, to swing.The latex tubing of its connection is big because of two ends caliber etc., many imprecisions when connecting syringe nipple, in the drawing liquid process, need to use thumb and forefinger fixedly latex tubing and syringe nipple joining place, very easily cause pneumothorax, even severe complication such as respiratory failure can appear, and bring misery and danger to patient, also make troubles to doctor's operation.
Summary of the invention
This utility model is the problem that exists at prior art, and a kind of multi-functional thoracentesis device is provided, and avoids syringe to pass replacing repeatedly in the journey at breast, and is easy and simple to handle, safe and reliable.
The purpose of this utility model is achieved through the following technical solutions: a kind of multi-functional thoracentesis device, comprise syringe, thoracic-puncture needle, connection tube, it is characterized in that: have first outlet of a three-way diverter valve to be connected with the nipple of described syringe, second outlet of three-way diverter valve connects a discharging tube, and the inlet of three-way diverter valve connects described thoracic-puncture needle with described connection tube.
To improvement of the technical scheme: a drainage bottle is inserted in the drain side of described discharging tube.
To further improvement in the technical proposal: described thoracic-puncture needle is a 12G venous transfusion pin, described connection tube is the 14G rubber urinary catheter, the butt end of 14G rubber urinary catheter connects 12G venous transfusion pin needle stand, and the thin end of 14G rubber urinary catheter connects the inlet of three-way diverter valve.
To further improvement in the technical proposal: described three-way diverter valve is a hand-operated valve, the inlet of three-way diverter valve is furnished with the joint that the thin port with the 14G rubber urinary catheter directly mates, first outlet of three-way diverter valve is furnished with the joint with the nipple bore of syringe coupling, and second outlet is furnished with the joint with discharging tube bore coupling.
This utility model compared with prior art has following advantage and good effect:
1, the commutation of this utility model by three-way diverter valve realizes imbibition, discharge opeing, avoided syringe to pass replacing repeatedly in the journey at breast, significantly reduced the possibility that pneumothorax is caused in the air admission thoracic cavity.
2, thoracic-puncture needle adopts 12G venous transfusion pin, the domatic gradient of its needle point is identical with thoracentesis needle, be 30 °, length is 38mm only, Clinical Practice proves that body weight is the patient of 90kg, and the thoracic wall thickness at its normal thoracentesis position also is no more than 36mm, so make thoracentesis with 12G venous transfusion pin, its length can reach paracentesis depth, and can not cause the back pin that puncture successfully to obstruct outside thoracic wall exposure again too much.Fixedly the person only needs to pinch the puncture needle needle stand with thumb and forefinger, and all the other respectively refer to and patient's thoracic wall fixed needle all is close in big hypothenar, and is fixing so very firm, effectively avoided because of the fixing not firm puncture needle swing that causes.
3, the latex tubing that replaces present internal diameter 4mm with the 14G rubber urinary catheter, because does not wait greatly at the caliber two ends, not only guaranteed tight with being connected of puncture needle, and it is tight that butt end is connected with syringe nipple, the doctor does not worry that when drawing liquid rubber tube separates with syringe nipple, also need not two refer to fixedly syringe and rubber tube junction, bring convenience to operation.In addition, rubber tube is more high temperature resistant than latex tubing, high pressure, and long service life is difficult for adhesion.
4, this utility model is made simply, and cost is lower, and is easy to utilize.
Description of drawings
Fig. 1 is the johning knot composition of the multi-functional thoracentesis device of this utility model.
The specific embodiment
Referring to Fig. 1, the embodiment of a kind of multi-functional thoracentesis device of this utility model, comprise syringe 1, three-way diverter valve 2, connection tube 3, thoracic-puncture needle 4, discharging tube 5, first outlet of three-way diverter valve 2 is connected with the nipple of described syringe, second outlet of three-way diverter valve is connected discharge opeing 5 pipes, and the inlet of three-way diverter valve 2 connects thoracic-puncture needle 4 with connection tube 3.A drainage bottle 6 or other containers are inserted in the drain side of discharging tube 5.
Above-mentioned thoracic-puncture needle 4 is 12G venous transfusion pins, described connection tube 3 is 14G rubber urinary catheters, the butt end of 14G rubber urinary catheter 3 (internal diameter 5.5mm) connects the needle stand of 12G venous transfusion pin 4, the thin end (internal diameter 2 mm) of 14G rubber urinary catheter 3 is cut 20cm, and the inlet with three-way diverter valve 2 is connected again.
Above-mentioned three-way diverter valve 2 is hand-operated valves, the inlet of three-way diverter valve 2 is furnished with the joint that the thin port with 14G rubber urinary catheter 3 directly mates, first outlet of three-way diverter valve 2 is furnished with the joint with the nipple bore of syringe 1 coupling, and three-way diverter valve 2 second outlets are furnished with the joint with discharging tube 5 bores coupling.
