Abstract
The utility model relates to a disposable multifunctional drainage device for thoracentesis. The disposable multifunctional drainage device for the thoracentesis comprises a sleeve, a thoracic puncture needle, a piston rod and a push rod. The rear portion of the thoracic puncture needle is connected at one end of the sleeve in a matched mode. One end of the piston rod is inserted into the other end of the sleeve and is matched with the inner wall of the sleeve. The push rod is connected with the other end of the piston rod. The disposable multifunctional drainage device for the thoracentesis is characterized in that a one-way valve is arranged on the rear portion of the thoracic puncture needle, and the one-way valve and the thoracic puncture needle form a whole. An internal thread is arranged on the inner wall of one end of the sleeve. An external thread is arranged on one end portion of the piston rod. The external thread and the internal thread are in corresponding fit. The disposable multifunctional drainage device for the thoracentesis has the functions of control over the exhausting speed and the liquid discharging speed, pressure measurement, medicine injection, automatic negative pressure drainage and observation over change in pressure in a thoracic cavity, and is simple in structure, small in size, light in weight, safe to operate, and capable of being used in a disposable mode and avoiding cross infection.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to the disposable multifunction breast and wears drainage device.
Background technology
When treatment hydrothorax, pneumothorax, Clinical Processing method commonly used has two kinds: the one, and closed thoracic drainage is to handle the most frequently used effective ways of pneumothorax, but need be at thoracic operation otch, intubated and drained, the medical care complicated operation, patient's misery is unbearably; The 2nd, thoracic drainage and thoracentesis, the general extraction hydrothorax (gas) that is used for is to reach diagnosis and therapeutic purposes.Adopting thoracic-puncture needle is the 16-20 medical needle, is connected with rubber tube at the tail end of syringe needle, and what have is provided with three-way valve at rubber tube.Name as CN 2710684Y bulletin is called " automatic negative-pressure drain thoracic-puncture needle " utility model patent, and it has a syringe needle, and the syringe needle rear portion is connected with three-way valve; One end of three-way valve by plastic tube be connected with cork, the other end is connected with depression drainage device with the flexible pipe gauge tap by flexible pipe.This automatic negative-pressure drain thoracic-puncture needle can carry out automatic drawing liquid, reach predetermined drawing liquid amount after, can stop voluntarily, but structure is complicated, it is not too convenient to operate.Therefore, require further improvement.
Summary of the invention
The purpose of this utility model provides the disposable multifunction breast and wears drainage device, it has control aerofluxus, drain age velocity, pressure measurement, injection, automatic negative-pressure drain, observe the function that intrathoracic pressure power changes, simple in structure, volume is little, in light weight, handling safety, disposable use can be avoided cross infection.
Disposable multifunction breast described in the utility model is worn drainage device, comprise sleeve, rear portion be connected the thoracic-puncture needle of sleeve one end, an end from the other end of sleeve insert and the piston rod that cooperates with sleeve lining, with the push rod that the piston rod other end is connected, it is characterized in that:
One check valve is located at the rear portion of described thoracic-puncture needle, and with thoracic-puncture needle be an integral body; The effect that check valve is set is the change of being convenient to injection, pressure measurement, dynamic observing intrathoracic pressure power, by closing check valve, can prevent that hydrothorax is excessive behind the taking-up syringe.
Inwall at described sleeve one end is provided with one section female thread, is provided with one section external screw thread in described piston rod one end, described external screw thread and described female thread corresponding matching.The female thread of sleeve lining and the external screw thread of piston rod are connected, so that the negative regulation that forms.
Further, the length that is located at one section female thread of described sleeve one end inwall is 4-6 centimetre, and the one section externally threaded length that is located at described piston rod one end is consistent with the length of female thread.External screw thread on the regulating piston bar and the length that is connected of the female thread on the sleeve lining can be controlled the speed of aerofluxus, discharge opeing.
Thoracic-puncture needle of the present utility model, sleeve, piston rod and push rod constitute a negative pressure syringe.When thoracic-puncture needle thrust in the body, the reach by regulating piston bar and sleeve cooperate can cause negative pressure, and after thoracic-puncture needle entered the thoracic cavity, intrathoracic hydrops (gas) flowed out under suction function automatically, thereby has improved puncture success rate.
This utility model is compared with prior art and is had the following advantages: owing to be provided with check valve at the rear portion of thoracic-puncture needle, so that injection, control discharge opeing (gas), prevent that hydrothorax is excessive, dynamic observe the change of intrathoracic pressure power; Because the inwall at sleeve one end is provided with one section female thread, is provided with one section external screw thread in piston rod one end, the external screw thread on the regulating piston bar and the length that is connected of the female thread on the sleeve lining can be controlled negative pressure, the speed of regulation and control aerofluxus, discharge opeing.
