Description

Special dredging tool for drainage catheter

Technical Field

The utility model relates to the technical field of medical equipment, a medical equipment of mediation drainage tube is related to, specifically a special dredging tool of drainage tube.

Background

The drainage of the catheter is widely applied to operations such as abdominal cavity, thoracic cavity, biliary tract, gastrointestinal tract and the like, one end of the drainage catheter is usually extended into an effusion area after the operations, and the other end of the drainage catheter is placed outside the body to discharge effusion, bloody pus and tissue fragments after the operations, so that the catheter is easy to block by blood clots and tissue fragments with large volume in clinic, or the drainage catheter is placed for a long time according to actual requirements, especially for more than 1 week, and is frequently blocked, and the blocking objects can be cellulosic exudates, pus and moss and blood clots.

The blockage caused by the two conditions is usually dredged by methods such as pinching, sucking and moving, but the effect is not obvious and can not be effective, or the blockage is dredged by a method of reverse flushing of physiological saline, the method needs better experience and operation methods of operators, otherwise the blockage can not be realized, and the blockage is dredged by a negative pressure sucking method.

In conclusion, a more professional tool is needed for dredging, the current dredging tools used clinically cannot better meet the requirements, and the economic burden of a patient and the operation intensity of medical staff cannot be better reduced. Therefore, the novel and professional dredging tool is designed to solve the clinical requirement, and the dredging tool has very high practical value and practical significance.

Drawings

FIG. 1 is a schematic view of a half-section structure of the present invention;

figure 2 is a partial structure diagram of the spiral coil of the present invention,

fig. 3 is a schematic view of the usage of the present invention.

In the figure: 1. the catheter comprises a supporting seat, 2 parts of a catheter, 201 parts of an inclined blade, 3 parts of a guide wire, 4 parts of a handle and 5 parts of a spiral coil.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

example one (not shown in the figure):

the utility model provides a special dredging tool of drainage catheter, including supporting seat 1, 1 one end of supporting seat is connected with pipe 2, be equipped with seal wire 3 in the pipe 2, 3 rear ends of seal wire run through supporting seat 1, 3 sliding connection of seal wire are in pipe 2 and supporting seat 1, 3 rear ends of seal wire are connected with handle 4, 3 front ends of seal wire are equipped with spiral coil 5, spiral coil 5 sets up in 2 outsides at the pipe, spiral coil 5 lay the direction unanimous with 3 length direction of seal wire, handle 4 drive seal wire 3 can accomplish in pipe 2 and stretch out and draw back, rotatory action, and then the spiral coil 5 that makes 3 front ends of seal wire can stretch out and draw back, rotatory action, and then destroy the plug, thereby reach the purpose of mediation.

When the drainage device is used, the supporting seat 1 is held, the catheter 2 is stretched into the drainage tube until the spiral coil 5 is contacted with a blockage, and the operating handle 4 drives the spiral coil 5 to rotate or stretch, so that the blockage is broken and taken out until drainage liquid flows out.

Example two (as shown in figures 1-3):

the spiral coil 5 is made of titanium-nickel memory alloy, the spiral coil 5 made of the titanium-nickel memory alloy can be completely contracted into the catheter 2, the passing performance of the catheter 2 in the drainage tube is better facilitated, and meanwhile, after the spiral coil 5 extends out of the catheter 2, the size of the spiral coil 5 can be changed along with the size of the inner diameter of the drainage tube, and the blockage in the drainage tube is better cleaned thoroughly.

The front end of the catheter 2 is provided with an inclined blade 201, and the inclined blade 201 can help the catheter to penetrate through the blockage, so that the blockage can be better cleaned.

Further helical coil 5 connect the one end of seal wire 3 to the tail end of helical coil 5 set up with the involute form, through the setting of the helical coil 5 of special construction, after pipe 2 passed the plug, rethread handle 4 stretches out helical coil 5 pipe 2, helical coil 5 formed the back taper structure this moment, this moment outwards pulled supporting seat 1 and handle 4 simultaneously, can pull out the plug under helical coil 5's effect, thereby realize the purpose of mediation, and because the back taper structure of helical coil 5 can effectively increase the area of contact with the plug, and then more effectively pull out the plug or directly break, and because helical coil 5 is made for titanium nickel memory alloy, 5 afterbody of helical coil and the inside wall of the drainage tube laminate completely this moment, can guarantee the comprehensive nature of mediation.

Further spiral coil 5 be provided with a plurality ofly, a plurality of spiral coil 5 extend 3 length direction of seal wire and connect gradually, can effectively increase the mediation ability through setting up a plurality of spiral coil 5 to reduce the number of times of mediation work, promote mediation work efficiency.

Further two adjacent spiral coil 5 set up opposite direction, utilize this special structural design to guarantee the utility model discloses an use and foretell effect can guarantee that a plurality of spiral coil 5 can smoothly stretch out or get into from pipe 2 simultaneously.

When the device is used, as shown in fig. 3, the spiral coil 5 is contracted into the catheter 2, the head of the catheter 2 is inserted into the drainage tube, the catheter 2 is slightly pushed forwards by holding the supporting seat 1, the inclined edge of the head of the catheter 2 completely penetrates through the blockage blocking part, the supporting seat 1 is fixed, the handle 4 is pushed forwards, the spiral coil 5 slides out of the catheter 2 to form one or more conical spiral coils 5, and then the supporting seat 1 and the handle 4 are pulled out of the drainage tube together, so that the dredging work is completed, and if the whole dredging work cannot be completed at one time, the steps can be repeated.
