In order to improve the utilization of a chest bottle set having a structure in which drainage of pleural effusion of patients with pleural fluid is drained through a pigtail catheter exposed to the outside of the chest toward a sealed drainage bottle or a one-way drainage bag, the present invention provides a sealed drainage bottle or one-way drainage from a pigtail catheter. A connecting gender is required between the envelopes.

The connecting gender is composed of a body part 100 having a connection pipe 200 for allowing the drained pleural effusion to flow into the upper part and a distribution pipe 300 to drain the inflow pleural effusion fluid at the lower part.

Inside the body part 100, a collection hole 110 is formed as a space of a predetermined size in which the inflow pleural effusion stays and is drained, so that the upper connection pipe 200 and the lower distribution pipe 300 pass through. do.

The connection tube 200 protruding from the upper part of the body part 100 is coupled to the pigtail catheter B connected to the chest tube on the chest side, and the guide tube having a lock jaw is inserted into the pigtail catheter C1. 210 extends and protrudes.

The distribution pipe 300 protruding from the lower part of the body 100 has a different inner diameter so that the cover tube of the sealed drainage bottle to be connected or the tube suitable for the diameter of the one-way drainage bag valve can be selected, so that the first pipe 310, The second tube 320 and the third tube 330 are formed.

The cap body 400 has an insertion hole 410 inserted into and coupled to the ends of the drain holes 301 of the first pipe 310, the second pipe 320, and the third pipe 330 having different diameters. The head 430 is provided with a diameter formed and the insertion state of the insertion hole 401 is caught at the end of the drain hole 301.

At the front end of the insertion hole 410, a locking jaw 411 is formed to provide a stable coupling state by increasing adhesion with the inner diameter of the drain hole 301, and the first pipe 310 and the second pipe 310 are inside the insertion hole 410. An inlet hole 401 connected to the drain hole 301 of the pipe 320 and the third pipe 330 to form a passage is provided.

A closing film 440 is provided in the inlet hole 401 to block the passage of the inlet hole 401 until the tube of the sealed drain bottle or the one-way drainage bag is coupled.

In forming the closed film 440, since the tube of the one-way drainage bag must be easily cut when coupled, it is formed as a thin film, but the thickness gradually increases from the thin film part 443 in the center to the inner wall side ( 441), and an incision 450 is formed on the surface of the closure film.

In forming the closing film 440, the center is thin and thick toward the inner wall, and the incision 450 is formed on the surface so that when the closing film 440 is cut, the inlet hole 401 is opened from the center to the inner wall. to spread out to the side.

In this way, as a way to open the closing film 440 from the center of the inlet hole 401 toward the inner wall, the incision 450 formed on the surface of the closing film 440 is radially formed from the center of the closing film 440. let it be

The cap body 400 is easily coupled to the distribution pipe 300 of the body 100, and in the coupled state, the tube of the sealed drainage bottle or the one-way drainage bag is smoothly inserted and the closing membrane 440 is formed. In order to be easily incised along the incision line 450, the material is formed of the same silicon material as the body portion 100, but a soft silicone material having a hardness value lower than the silicon hardness value of the body. desirable.

Figure 5 shows a state of selectively connecting the pigtail catheter and the connecting gender of the present invention, Figure 6 is a longitudinal cross-section showing the coupling structure of the cap body of the present invention, (a) is the state before coupling and (b) is the combined state indicate state.

The drainage of pleural effusion of patients with pleural fluid is guided to the outside of the chest through a pigtail catheter (B) (tube-type chest tube, pig tail chest tube) as shown in FIG. 5 (a), and as shown in FIG. Or, as shown in FIG. 5 (C), between the one-way drainage bag 500 or the sealed drainage bottle 600, in order to improve the utilization method with the chest bottle set having a structure for draining to the sealed drainage bottle 600 side, the connection gender of the present invention Even if the size of the chest bottle set is different due to the installation, it is possible to extract pleural effusion.

That is, the connector 200 protruding upward from the body portion 100 of the connecting gender is coupled to the pigtail catheter B as shown in FIG. 5(b) or FIG. 5(c) and protrudes downward from the body portion 100. When the distribution pipe 300 is coupled to the one-way drainage bag 500 or the sealed drainage bottle 600, each distribution pipe 300 of the body 100 has a different diameter, so the one-way drainage bag 500 Alternatively, a distribution pipe having a diameter matching the standard of the valve tube of the sealed drainage bottle 600 may be selected.

In addition, since the material is made of silicone, it is inserted in an extended state into the valve tube of the one-way drainage bag (500) or sealed drainage bottle (600) that must be connected to the pleural effusion drainage step due to the elasticity of the material even if the diameter does not completely match. Therefore, the selectivity of the standard is accepted.

As shown in FIG. 5, when the connecting gender is applied to the tube of the one-way drainage bag 500 or the sealed drainage bottle 600, any one of the first pipe 310 to the third pipe 330 selected from among the distribution pipes 300 The cap body 400 having a diameter that can be inserted into the end of the tube is approached as shown in FIG. 6A to the drain hole 301 of any one of the first to third tubes selected by the insertion hole 410 as shown in FIG. 6B. When inserted, the insertion port 410 is inserted into the drain hole 301 of any one of the selected first to third pipes, and the head 430 is caught at the end of the drain hole 301 to drain any one of the distribution pipes 300. The cap body 400 is coupled to the end of the tube, and the locking jaw 411 of the insertion hole 410 adheres to the inner wall surface of the drainage hole 301, thereby stabilizing the coupling state.

7 shows a state in which the connection gender of the present invention is installed in a pigtail catheter or a Heimlich valve, (a) is a state in which a one-way drainage bag is connected, and (b) is a state in which a sealed drainage bottle is connected.

In this way, the valves 510 and 610 of the one-way drainage bag 500 or the sealed drainage bottle 600 are inserted into any one of the distribution pipes 300 of the body part 100 to which the cap body 400 is coupled, as shown in FIG. When connected in the state as shown in (a) or FIG. 7 (b), at this time, due to the elongation characteristics of the silicon material, it is coupled to the valve 510 or 610 while being stretched.

Figure 8 is a cross-section in which the one-way drainage bag and the sealed drainage bottle are coupled to the distribution pipe of the body to which the cap body is coupled, (a) shows a state in which the coupling is started, and (b) shows a state in which the coupling is completed.

The inlet hole of the cap body 400 in which the valves 510 and 610 of the one-way drainage bag and the sealed drainage bottle are inserted into the drainage hole 301 of any one of the first pipe 310 to the third pipe 330 ( 401), the closing film 440 in the form of a thin film blocking the inside of the inlet hole 401 is torn by the entry force of the valves 510 and 610 and spreads along the incision line 450 and continues. The closing film 440 torn by the entry of the valves 510 and 610 spreads from the center toward the inner wall.

When the closing film 440 is torn by the insertion of the valves 510 and 610, the inflow hole 401 is opened and the one-way drainage bag and sealed drainage bottle valves 510 and 610 are connected. The pleural effusion collected in the collection hole 110 of the unit 100 passes through the drainage hole 301 of the distribution pipe 300, the inlet hole 401 of the cap body 400, and the valves 510 and 610 to form a one-way drainage bag. 500 and the sealed drain bottle 600 are drained into the inner space.

Since the closing film 440 inside the cap body 400 is not cut before the first tube 310, the second tube 320, and the third tube 330 of the distribution tube 300 are inserted, the body portion 100 The collection hole 110 of ) is blocked, and the pleural effusion is maintained in the collection hole 110.

Since the distribution pipe 300 including the body part 100 of the connecting gender of the present invention is formed of a silicon material, the first pipe 310, the second pipe 320, and the third pipe 330 are unidirectional drainage bags 500 ) and the drain hole 301 may be temporarily locked by biting tongs and a clamp, if necessary, before coupling to the sealed drain bottle 600.

In addition, since the distribution pipe 300 of the connecting gender is made of silicon material and the diameters of the first pipe 310, the second pipe 320, and the third pipe 330 are formed differently, the relatively coupled one-way drainage bag ( 500) and the valves 510 and 610 of the sealed drain bottle 600, if the specifications do not match, you can select one that meets the specifications among the first pipe 310, the second pipe 320, and the third pipe 330. In addition, when these valves 510 and 610 are inserted, they are combined in an elongated state due to the characteristics of the silicone material, so the inconvenience of the operation due to the non-matching specifications of the connection part of the chest bottle set is eliminated.

In particular, the closure film 400 of the cap body 400 is very thin at the central position in the state where the incision 450 is formed and gradually becomes thicker towards the inner wall of the inlet hole 401, so that the one-way drainage bag 500 ) and when the valves 510 and 610 of the sealed drainage bottle 600 are inserted, the thin film portion 443, which is a thin portion of the closing film 440, along the incision line 450 as shown in FIG. As it is easily torn, it is easily opened in the direction of insertion of the valve 510 (610), and the thick portion 441 adheres to the outer surface of the valve 510 (610) inserted as shown in FIG. 8 (b). As it is, the outer surface of the valve 510 or 610 is pressurized and adhered to with the elasticity of the thickness.

Such a closing membrane 440 is easy to insert into the inserted valves 510 and 610 and forms a structure that increases adhesion and frictional force in the inserted state. In a state where the specifications of the envelope 500 and the sealed drain bottle 600 do not match, the coupling is stabilized, and since the adhesion is made high, the inflow of air from the outside to the inside of the pipe is reliably blocked.
