Embodiment is substantially as shown in Fig. 1: a kind of kidney internal medicine catheter injection device, including injection tube, injection tube
Including injection-tube 2, first piston 3 and push-pull rod 1, first piston 3 is located in the injection-tube 2, first piston 3 and injection-tube 2
Movable closed connection, 3 rear end of first piston connect the push-pull rod 1, and push-pull rod 1 is stretched out from the rear end of injection-tube 2, by manual
Control push-pull rod 1 is just able to achieve injection tube and carries out injection flushing liquor and suction irrigation liquid.
The front end of injection-tube 2 is communicated with outlet tube 11 and liquid suction pipe 13, and the first check valve 9 is equipped on outlet tube 11；It takes out
Second piston is equipped in liquid pipe 13, as shown in Fig. 2, being fixedly connected with telescopic rod between second piston and the front end of first piston 3
4, the baffle 14 for preventing second piston from stretching out from nozzle, the tube wall of outlet tube 11 are equipped at the both ends nozzle of liquid suction pipe 13
On be communicated with drain pipe 16, second one-way valve 15 is installed on drain pipe 16.In order to collect the waste liquid being discharged from drain pipe 16, this reality
It applies in example, further includes having liquid-collection bag 17, the nozzle of drain pipe 16 is connected to liquid-collection bag 17.The bottom of liquid-collection bag 17 is equipped with drain
Mouthful, leakage fluid dram is equipped with switch.Liquid-collection bag 17 is equipped with graduation mark, in order to metering liquid discharge rate.
Since the nozzle of the cleaning injection port of existing catheter is smaller, 0.5-0.7 centimetres of caliber average out to, thus
So that outlet tube 11 and 13 inconvenience of liquid suction pipe are connect with catheter simultaneously, so further including for that will inject in the present embodiment
The connector that cylinder is connect with catheter.As shown in figure 3, connector includes casing 10, connecting tube 18 and connect with catheter thin
Pipe 19, outlet tube 11 and liquid suction pipe 13 are fixedly connected in casing 10, and the first check valve 9 of outlet tube 11 is located at casing 10
Outside, to adjust；Drain pipe 16 on liquid suction pipe 13 is located at outside casing 10, to connect liquid-collection bag 17.One end of connecting tube 18
It is threadedly coupled with casing 10, the outer wall of connecting tube 18 is equipped with external screw thread, and the inner wall of casing 10 is equipped with internal screw thread；Connecting tube 18 it is another
One end is fixedly connected with tubule 19.
In the present embodiment, injection tube is 100ml capacity, and the tube wall of injection-tube 2 is equipped with graduation mark.
Complete bladder irrigation during, i.e., bladder is repeated until physiological saline 500ml is rinsed finish completely
In the process, injection tube needs repeatedly to extract flushing liquor, also just need to connect with connecting tube 18 for the casing on injection tube more than 10 times and
Separation realizes that injection tube is separated with catheter, and injection tube can carry out extraction flushing liquor.But injection tube is connect with catheter repeatedly
And separation, so that it is troublesome in poeration, it further include liquid storage bottle 7 in the present embodiment, liquid storage bottle 7 is equipped with to improve working efficiency
Liquid mouth and inlet.The tube wall of injection-tube 2 is communicated with inlet tube 5, and inlet tube 5 is equipped with third check valve 8, and liquid storage bottle 7 goes out
Liquid mouth is connected to inlet tube 5.The tube wall of injection-tube 2 is fixed with support frame, and support frame as described above includes annular iron ring 6, and liquid storage bottle 7 is set
In in annular iron ring 6.Liquid storage bottle 7 can be equipped with flushing liquor in advance.
Specific implementation process is as follows: tubule 19 connects catheter, and connecting tube 18 is screwed with casing 10, closes the first check valve
9 and second one-way valve 15, third check valve 8 is opened, push-pull rod 1 is then slowly pulled, so that the flushing liquor of liquid storage bottle 7 is extracted
Into injection-tube 2.When pulling push-pull rod 1, the rear extreme direction that push-pull rod 1 drives first piston 3 toward injection-tube 2 is mobile, and first
Piston 3 is mobile to drive second piston mobile by telescopic rod 4, when second piston is moved to liquid suction pipe 13 and 2 connector of injection-tube
When place, stopped by the baffle 14 of 13 nozzle of liquid suction pipe, second piston no longer moves, and first piston 3 continues to move to, then pulls flexible
Bar 4 extends, and second piston can stop the flushing liquor extracted to flow into catheter from extraction tube.
When first piston 3 is moved at the back-end ports of injection-tube 2, the extraction of injection-tube 2 is finished, and is then started to catheter
Inject flushing liquor.At this point, opening the first check valve 9, third check valve 8 is closed, push-pull rod 1 is slowly pushed, drives first piston 3
The preceding extreme direction of reverse movement, i.e. first piston 3 toward injection-tube 2 is mobile, thus by the flushing liquor in injection-tube 2 from outlet tube 11
It promotes in road catheter.In 3 moving process of first piston, first piston 3 drives second piston reverse movement again, when the second work
Plug is moved to extraction tube and is not connected at the nozzle of injection-tube 2, is stopped by the baffle 14 at the nozzle, and second piston no longer moves,
First piston 3 continues to move to, then telescopic rod 4 is pushed to shorten.
After flushing liquor is all introduced into bladder, when needing that intravesical flushing liquor is sucked out, the first check valve 9 is closed, is beaten
Second one-way valve 15 and third check valve 8 are opened, then pulls push-pull rod 1, second piston is mobile toward 2 direction of injection-tube, i.e., in bladder
Flushing liquor from extraction tube extract out, then by drain pipe 16 enter liquid-collection bag 17 in.And while pulling push-pull rod 1, liquid storage
The flushing liquor of bottle 7 is drawn into again in injection-tube 2.After intravesical flushing liquor is sucked out, and aforesaid operations are repeated, carried out
Bladder cleaning.
In the cleaning process of bladder, this programme does not need replacement injection tube not only, just can be completed by an injection tube
Flushing liquor is injected into bladder, and intravesical flushing liquor is sucked out, and while flushing liquor is sucked out, can also be to note
Shooting cylinder injects flushing liquor, saves the working time, and the push-pull rod 1 for pushing away a drawing injection tube by one can realize the cleaning of bladder,
It reduces troublesome in poeration, improves work efficiency.
