Technical Field
The utility model belongs to the technical field of auxiliary medical instrument, concretely relates to get stone catheterization drainage tube.
Background
After the existing extracorporeal ultrasonic lithotripsy operation, most of the patients need to urinate by themselves to realize the excretion of the lithotripsy, the possibility of remaining urethra or bladder is caused by the excretion mode, and secondly, the possibility of secondary incised wound on the urethra exists in the stones which are not completely smashed in the excretion process, so that hematuria is caused, psychological pressure is caused to the patients, and whether the patients excrete cleanly or not cannot be judged; the flexible ureteroscope laser lithotripsy technology is developed under the environment, but after the existing flexible pipe is placed into the lithotripsy, the completely crushed calculus is discharged from the flexible pipe along with urine, and the removal and discharge effect is not obvious.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that the crushed stone in the prior art is discharged passively along with the urine instead of being cleaned actively and removed, the utility model provides a stone-taking catheterization drainage tube which can cause the residual stone in the body to be discharged unclean.
The technical solution of the utility model is that: a stone-taking catheterization drainage tube comprises a hose, wherein the drainage tube is also arranged in the hose, a cavity between the drainage tube and the hose is a water injection cavity, one end of the outer side wall of the hose, which is close to an extending end, is provided with at least one air bag, and a vent pipe of the air bag extends out from the tail end of the hose through the water injection cavity; after laser lithotripsy, certain medicinal liquid is injected into the affected part through the water injection cavity, so that the crushed stone is pumped out of the drainage tube along with the injected liquid, namely the crushed stone at the affected part is impacted by the liquid to form turbid liquid and is brought into a water path formed by the water injection cavity and the drainage tube to be cleaned.
Further, the expansion state of the air bag is butterfly-shaped.
Further, the number of the air bags is 3.
Furthermore, a communicating pipeline is arranged between each air bag, so that the drainage tube between the air bags is communicated with the outside.
Furthermore, a clear water polymer coating is arranged on the outer wall of the hose.
Furthermore, the tail end of the drainage tube is divided into two parts, and the two parts comprise a drainage port and a laser fiber mounting port which are in a shape of a Chinese character Bu.
Furthermore, the hose, the drainage tube, the air bag and the vent pipe are all made of medical silica gel materials.
The utility model has the advantages that: through the utility model discloses stretch into the design in the intercommunication water route that end water injection chamber and drainage tube formed for along discharging into to the drainage by the washing liquid that the kibbling calculus of laser was followed and is got into through the water injection chamber, thereby initiative and quick clean up kibbling calculus, the effect is instant, and need not with the utility model discloses stay for a long time and arouse the unnecessary condition of bleeding in vivo.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a hose; 2. a drainage tube; 3. a water injection cavity; 4. an air bag; 5. a breather pipe; 6. a communicating pipe; 7. an air interface 8 and a water filling port; 21. a drainage opening; 22. laser fiber installing port.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
Example 1
As shown in fig. 1, the structure of the present invention is: a stone-taking catheterization drainage tube comprises a hose 1, wherein a drainage tube 2 is further arranged in the hose 1, a cavity between the drainage tube 2 and the hose 1 is a water injection cavity 3, one end of the outer side wall of the hose 1, which is close to an extending end, is provided with at least one air bag 4, and a vent pipe 5 of the air bag 4 extends out of the tail end of the hose 1 through the water injection cavity 3; in the embodiment, the holmium laser fiber is guided into the stone affected part through the drainage tube 2, after laser lithotripsy, certain medicinal liquid is injected into the affected part through the water injection cavity 3, so that the crushed stone is pumped out from the drainage tube along with the injected liquid, namely, the crushed stone at the affected part is impacted by the liquid to form muddy liquid and is brought into a water path formed by the water injection cavity 3 and the drainage tube 2 to be cleaned.
As a preferential technical scheme, the expansion state of the air bags 4 is butterfly-shaped, and a plurality of air bags 4 are combined and connected in series, so that the cavity of the human body can be blocked more easily within a short distance.
In this embodiment, gasbag 4 is 3, and the cluster form links to each other, and a sharing breather pipe 5 is convenient for the utility model discloses an installation is fixed, the shutoff of also being convenient for.
As a preferential technical scheme, a communication pipeline 6 is arranged between each air bag 4, so that the drainage tubes 2 between the air bags 4 are communicated with the outside, liquid entering a space formed by the air bags 4 and a human body cavity can be pumped away by the drainage tubes 2, and blockage is reduced.
As a prior technical scheme, the outer wall of the hose 1 is provided with the clear water polymer coating, when the catheter is used, the catheter can reach a highly lubricated state only by being wetted by normal saline, and the catheter is easy to use under the stimulation of the urethra.
