Detailed Description
The invention will be described in further detail with reference to the following figures and specific embodiments:
the pressure extension tube with the liquid drainage device for the interventional operation comprises a main tube, wherein one end of the main tube is a high-pressure syringe connecting end 1, the other end of the main tube is an interventional consumable connecting end 2, the liquid drainage device is further arranged on the main tube and comprises a liquid storage cavity 3 communicated with the main tube and a piston 5 capable of moving in the liquid storage cavity 3, the piston 5 extends out from one end, far away from the main tube, of the liquid storage cavity 3, and a piston head 6 of the piston 5 is connected with the inner wall of the liquid storage cavity 3 in a sealing mode. The highest position of the piston head which can rotate to push and extend into the liquid storage cavity does not exceed the plane of the contact part of the main body pipe and the liquid storage cavity. The high-pressure injector connecting end is used for connecting a high-pressure injector, the high-pressure injector injects the contrast medium into the pressure extension tube, and the intervention consumable connecting end is connected with intervention consumables; drainage device communicates with each other with the main part pipe, including stock solution chamber and piston, the stock solution chamber is used for the part contrast medium that the high-pressure syringe of temporary storage injects into the pressure extension intraductal, the piston is used for storing or pushing out the contrast medium in the stock solution chamber with the cooperation of stock solution chamber, reach the effect of discharge pressure extension pipe intervention consumptive material link air through push-and-pull piston, the doctor one-hand rotatory push-and-pull piston volume of controlling discharge contrast medium more easily during the operation, intervention consumptive material end can be pressed to the other hand, reduce the extravagant and intraoperative hemorrhage of contrast medium, can save operating time, alleviate surgeon's mental pressure, the piston head and the stock solution intracavity wall sealing connection of piston, both can prevent that the air from passing through piston department gets into the main part pipe, can. The utility model discloses conveniently exhaust air reduces the extravagant and intraoperative hemorrhage of contrast medium, and can save the operation time, alleviates doctor's mental stress.
As preferred, stock solution chamber 3 keeps away from main part pipe one end and still is provided with stopper 4 that is used for restricting the motion of piston 5, and stopper 4 cup joints in the piston 5 outside. Stock solution chamber and main part pipe integrated into one piece, stopper fixed connection keeps away from main part pipe one end in the stock solution chamber for prevent that piston rod portion from rocking in the motion process, the stopper can carry on spacingly to the pole portion of piston, guarantees the steady of piston motion.
Preferably, the inner wall of the limiting block 4 is provided with threads, and the outer side of the piston 5 is provided with matched threads. Accessible screw thread and piston connection in the stock solution intracavity make the motion of piston more firm, and threaded connection steerable piston speed of removing reduces the contrast medium waste when the exhaust air.
Preferably, the drainage means are arranged in proximity to the connection end 2 of the interventional consumable. The drainage device is arranged close to the position of the connection end of the intervention consumable, so that the air of the connection end of the intervention consumable of the pressure extension pipe can be discharged more quickly by one hand of an operating doctor, and the operation time is saved.
Before use, the high-pressure syringe connecting end 1 of the utility model is connected with the high-pressure syringe, and the piston 5 is arranged at a preset initial position (the liquid storage cavity is far away from one end of the main tube), so that the piston head 6 is tightly attached to the bottom of the liquid storage cavity 3 to provide the largest contrast medium storage space; simultaneously with the main part pipe vertical placement, intervene consumptive material link 2 and be located the top, high pressure syringe link 1 is located the bottom. When the device is used, firstly, the high-pressure injector is opened by one hand to manually inject the contrast medium into the main body tube, meanwhile, the intervention consumable connecting end 2 is pressed by the other hand, the contrast medium flows into the liquid storage cavity 3, and at the moment, the liquid storage cavity 3 is filled with the contrast medium; when air needs to be discharged, the high-pressure injector is closed, the piston 5 is rotated and pushed by one hand to enable the contrast agent stored in the liquid storage cavity to enter the main body tube and flow to the interventional consumable connecting end 2, and therefore the air in the main body tube is discharged; opening the high-pressure injector to enable the contrast agent to flow into the liquid storage cavity 3 through the main body pipe, closing the high-pressure injector when the liquid storage cavity 3 is filled with the contrast agent, pushing the piston 5 to enable the piston head 6 to move towards the main body pipe, pushing the contrast agent stored in the liquid storage cavity 3 into the main body pipe, enabling the contrast agent to move towards the interventional consumable connecting end 2 at the moment, and discharging air in the main body pipe when the contrast agent is just pushed out of the interventional consumable connecting end 2; when the high-pressure injector injects the contrast medium with a large dose, the pressure in the main body tube is large, so that the piston 5 in the liquid storage cavity 3 is screwed to a preset position by the pressure for discharging liquid for next contrast.
When preparing to connect the pressure extension tube for radiography, the piston is slightly rotated to ensure that the liquid storage cavity discharges the contrast medium so as to extrude the air at the connecting end of the intervention consumable of the pressure extension tube, so that the air is connected with the intervention consumable and radiography is carried out; when the high-pressure injector injects the contrast medium with a large dose, the piston can be pushed back to the position of one end of the main body pipe away from the liquid storage cavity due to the high pressure in the pressure extension pipe, so that the liquid storage cavity is filled again for the next contrast liquid drainage. Often will change the pipe of many different grade types in the operation is intervene to same platform, and when changing the pipe, the bubble is sneak into most easily in the position that pressure extension pipe and radiography pipe are connected, if use the utility model discloses a pressure extension pipe, then can conveniently discharge the bubble fast, save operation time, and need not other people and help the operation doctor one hand to operate, and the consumptive material link can be pressed to intervene to another hand, reduces the intraoperative hemorrhage and operation doctor's mental pressure.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
