[0002] Drainage port of medical solution bag [0003]

[0001] The present invention relates to a drain port provided in a receiver bag for insertion of a spike. More specifically, the present invention relates to a drain port connected to a lower portion of the hollow body, And a flexible inner auxiliary cap provided between the rubber cap and the finishing cap. The fluid port is provided with a rubber stopper to be mounted, a sealing cap coupled to an upper end of the port body to cover the rubber stopper, and a soft inner auxiliary cap provided between the rubber stopper and the finishing cap.

Parenteral nutrition, peritoneal dialysis solution, and blood, which are administered to patients for medical purposes, are mainly used in medical solution bags of non-PVC materials. . These fluid bags are usually provided with a drainage port and an injection port. The drainage port is used for draining a drug stored inside the bag by inserting a spike. The injection port is used for injecting another drug such as antibiotics into the bag by inserting a syringe.

In general, there is a rubber spike or a syringe in the port inside the medical fluid bag. However, in the case of an injection port, there is no problem because a narrow needle is inserted into the rubber stopper. However, in the case of a drain port in which a coarse spike is inserted, it is difficult to insert a spike into a rubber stopper, There is a concern.

In order to solve such a problem, the inventor of the present invention has found that, in the Utility Model Registration No. 20-0429645 (October 19, 2006), the upper layer cylindrical portion and the lower layer cylindrical portion are formed to have a single layer structure, And a conical groove portion is formed at the center of the lower surface of the lower layer cylindrical portion.

In the drain port using the rubber stopper, there is an effect that the insertion of the spike is easy, the spike falls naturally in the course of the drainage, and the leakage does not occur in the spike mark. However, rubber fragments are generated in the process of piercing the spike in the rubber stopper It could not solve the concern that it might enter the human body.

In order to alleviate such concerns, a drain port not using a rubber stopper is introduced in a utility model registration No. 20-0452452 (February 21, 2011). The drain port of such a structure is not likely to generate rubber debris due to spikes, but the structure is complicated because the injection tube must be closed with an auxiliary plug so that the drug remaining in the bag does not flow out after the spike is taken out There is a drawback that it is inconvenient to use.

However, in order to more easily explain the structure of each component, the vertical direction will be described with reference to FIGS. 1 and 2 for convenience.

1 and 2, the drain port for a sapabine according to the present invention includes a port body 10, a rubber stopper 20, a finishing cap 30, and an inner auxiliary cap 40.

1 and 2, the port body 10 has a cap housing 11 having an enlarged diameter at its upper portion, and a sealing tube body 12 coupled to a receiver bag at the lower side thereof. Is formed. The sealing tube 12 may be sealed directly to the fluid bag or may be inserted into a tube sealed in the fluid bag.

In the former case, it is preferable that the sealing tube body 12 has a rhombic shape so that the sealing work can be facilitated. In the latter case, the sealing tube body 12 has a cylindrical shape having a diameter corresponding to the tube. 1 shows a case where the sealing tube 12 has a rhombic shape.

Next, the rubber stopper 20 is mounted inside the cap housing 11, and is made of a common rubber material. As shown in FIGS. 2 and 3, the rubber stopper 20 has a guide hole 21 for guiding the spike to be inserted in a close contact state in the center of the upper surface, 22 are provided.

A cut-away portion 22a through which the lower end of the spike passes is formed at the center of the cut-off film 22. An annular cut-off portion 23 surrounding the cut-out 22a is formed on the bottom of the cut- It is preferable that it is projected downward. The incisional reduction 22a is incised, for example, in a cross shape. Thus, when the spike enters into the incision 22a, the scraper 23 is pushed out and supported between the inner wall of the sealing tube 12 and the spike so that the spike does not escape.

The blocking membrane 22 functions to prevent the drug stored in the liquid bag from flowing out in a state in which the spike is removed. Therefore, the cut-off surface 22 of the cut-off film 22 should have a thickness sufficient to prevent leakage of the cut-off between the cut-outs 22a due to the elasticity of the rubber cut- do.

The finishing cap 30 may be any structure among the finishing caps of known infusion bag ports as long as the finishing cap 30 surrounds the rubber stopper 20 and is coupled to the inside of the cap housing 11. [ 1 and 2 illustrate a flip-off finishing cap 30 as an embodiment of the present invention.

The lower end of the fixed cap 33 is fixedly coupled to the cap housing 11 and the upper end of the fixed cap 33 is provided with a separating ring 32 supported by a plurality of connecting ribs 31 at the upper center. The separation cap 35 covers the upper end of the cap housing 11 and is provided at the center of the lower surface with a locking protrusion 34 inserted into the separation ring 32 as shown in FIG.

2, the fixing cap 33 and the separating cap 35 are separated from each other by heating and pressing the end of the locking projection 34 'in a state where the locking projection 34 is inserted into the separation ring 32, . The flip-off type finishing cap 30 is provided in a state where the fixing cap 33 and the separation cap 35 are coupled by the engagement protrusion 34 'as shown in FIG.

As another example, the finishing cap 30 may be a so-called easy-peel film structure in which a finishing film (not shown) is directly attached on the fixing cap 33. In this case, the fixing cap 33 does not need to have the same structure as the connecting rib 31 and the separating ring 32, and the spike can be inserted immediately after removing the finished film.

Finally, the inner auxiliary cap 40 is installed between the rubber stopper 20 and the finishing cap 30, and is made of soft synthetic resin. The inner auxiliary cap 40 is preferably made of a polypropylene resin having a Shore A hardness of 70 to 100. 2 and 4, the structure of the inner auxiliary cap 40 includes an upper plate 41 that covers an upper surface of the rubber stopper 20 and a lower plate 41 that protrudes downward from the center of the bottom surface of the upper plate 41 And a guide tube (42) accommodated in the guide hole (21).

The guide tube 42 has a function of guiding the insertion of the spike and has an inner diameter which is in close contact with the outer diameter of the spike and is received in the guide hole 21 of the rubber stopper 20 in a close contact state. Thus, the spike passing through the upper plate 41 passes through the guide hole 21 while being in close contact with the inner circumferential surface of the guide tube 42.

According to a preferred embodiment of the present invention, the inner auxiliary cap 40 is formed with a downwardly bent hooking protrusion 43 at the edge of the upper plate 41. The upper end of the hooking jaw 43 are provided on the outer circumferential surface thereof. The outer circumferential surface of the guide tube 42 is formed with an outward trough 44 and an inner circumferential groove 25 corresponding to the outward trough 44 is formed on the inner circumferential surface of the guide hole 21. . The engagement protrusions 43 and the engagement grooves 24 and the outward protrusions 44 and the inward turning grooves 25 function to improve the sense of unity between the rubber stopper 20 and the inner auxiliary cap 40 .

2, the drain port for a sapabine according to the present invention includes a port body 10, a rubber stopper 20, a finishing cap 30, and an inner auxiliary cap 40, The sealing tube 12 of the body 10 is installed in the liquid bag. In order to drain the drug stored in the liquid bag, the separation cap 35 of the finishing cap 30 is first removed. 2, the separation rib 32 is disengaged together with the separation cap 35 while the connection rib 31 is cut off, and the separation ring 32 is separated from the central portion of the upper plate 41 of the inner auxiliary cap 40 Is exposed to the outside

The spikes are inserted into the guide holes 21 of the rubber stopper 20 in a state in which the spikes are in close contact with the guide tube 42. In this state, when the spikes are inserted into the center of the upper plate 41 of the inner auxiliary cap 40, Then, it passes through the barrier film 22. At this time, the spike is firmly supported on the inner wall of the sealing tube 12 as the cover 23 provided on the bottom of the blocking film 22 is pushed out.

As described above, since the spit is inserted into the guide hole 21 of the rubber plug 20 through the guide tube 42, the rubber plug 20 is not pushed when the spike is inserted There is no fear that rubber debris will be generated in the rubber stopper 20,

Therefore, the present invention has a wide effect of selecting the material of the rubber stopper 20. Conventionally, a rubber material of a special material is used to prevent rubber debris from being generated in the rubber stopper 20 when the spike is inserted.

In addition, in the state where the spike is inserted, the bare portion 23 of the rubber stopper 20 firmly catches the spike inserted in the guide tube 42 together with the guide tube 42, so that the spike may be shaken or may come out by itself none.

Since the spike passes through the incision 22a, the incision surface of the incision 22a is brought into close contact with each other due to the elasticity of the rubber stopper 20 without leaving spike marks even after the spike is removed, I never do that.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, the scope of the present invention is not limited by these embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
