Description

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

The present invention relates to a drain port used for insertion of a spike, which is installed in a liquid bag, and more specifically, a hollow port body having a lower portion coupled to a liquid bag, A rubber inner cap disposed on the inner cap, and a finishing cap coupled to an upper end of the port body to cover the rubber stopper.

Various infusions, peritoneal dialysis fluids, blood, etc., which are administered to the patient for medical purposes, are mainly stored in non-PVC plastic infusion bags. A drainage port used for draining a drug stored in the bag by inserting a spike is usually used for injecting another drug such as an antibiotic into the bag by inserting a syringe. An injection port is installed.

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 into which a coarse spike is inserted, a rubber stopper is inserted into the rubber stopper, It is difficult to insert the spike, and leakage may occur in the spike marks.

In order to solve such a problem, the inventor of the present invention has found that, in the Utility Model Registration No. 20-0429645 (Oct. 19, 2006), the upper layer cylindrical portion and the lower layer cylindrical portion are formed as a single layer structure, There is proposed a rubber stopper in which a circular arc groove portion is formed and a conical groove portion is formed at the center of a 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.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 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. As shown in FIGS. 1 and 2, the drain port for the liquid bag according to the present invention comprises a port body 10, an inner cap 20, a rubber stopper 30, and a finishing cap 40.

First, the port body 10 is a hollow tube body, and a sealing tube body 11 sealed at a rim of an infusion bag is provided at a lower portion thereof. A cylindrical cap housing 12 having a larger diameter is integrally formed at an upper portion thereof. . The sealing tube 11 may be thermally fused 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 11 is formed in a diamond shape so as to facilitate the sealing work. In the latter case, the sealing tube body 11 has a cylindrical shape having a diameter corresponding to the tube. FIG. 1 illustrates a case where the sealing tube 11 is in the shape of a rhombus.

3, the inner cap 20 is mounted in the cap housing 12 and is made of a soft material through which spikes can penetrate. The inner cap 20 includes a shielding film 21 and a lower holding tube 22, An upper support tube 23, and a support platform 24. The shielding film 21 covers the upper end of the sealing tube 11, and is a portion through which a spike (not shown) penetrates in the future.

The lower gripper tube 22 protrudes from the bottom surface of the blocking membrane 21 and is closely inserted into the inner surface of the sealing tube body 11 as shown in FIG. The upper support tube 23 protrudes in a direction opposite to the lower gripper tube 22, that is, on the upper surface of the blocking film 21. [ At this time, it is preferable that the diameter of the upper support pipe 23 is slightly smaller than the diameter of the lower branch pipe 22. The support foil 24 protrudes upward at a predetermined interval around the upper support pipe 23 at the edge of the barrier 21.

The rubber stopper 30 is installed on the inner cap 20 and is made of a conventional rubber material and has a spike penetration portion 31 and a downward support portion 32 and an outward step 33, .

The spike penetration part 31 is a part through which a spike (not shown) penetrates in the future, and is disposed on the blocking film 21 with the upper support pipe 23 interposed therebetween. Therefore, as shown in FIG. 2, the inside of the upper support tube 23 becomes empty. It is preferable that concave grooves 31a and 31b are depressed to facilitate insertion of spikes in the upper surface and the center of the bottom surface of the spike penetration portion 31, respectively.

2, the downward support portion 32 is protruded downward from the bottom surface of the spike penetration portion 31 and extends between the bottom support tube 22 and the support foil 24 of the inner cap 20 . An outwardly extending step 33 is formed on the outer periphery of the downward support part 32 to sit on the support fork 24.

The inner cap 20 and the rubber stopper 30 are preferably insert injection-molded in one body. The inner cap 20 is preferably made of a polypropylene resin having a Shore A hardness of 70 to 100 so that spikes can easily penetrate the shielding film 21 while sufficiently supporting the rubber stopper 30.

2, an upper end of the sealing tube 11 is provided with a latching protrusion 13 protruding upwards into the cap housing 12, and the lower capping tube 22 of the inner cap 20 And a supporting groove 25 corresponding to the engaging shoulder 13 is recessed between the supporting shaft 24 and the supporting shaft 24. The latching protrusion 13 and the latching groove 25 function to catch the inner cap 20 so that the inner cap 20 is not pushed down when the spike passes through the cut-off 21.

The finishing cap 40 may have any structure among the finishing caps of known infusion bag port as long as the finishing cap 40 surrounds the rubber stopper 30 and is coupled to the inside of the cap housing 12. [ 1 and 2 illustrate a flip-off finishing cap 40 as one embodiment of the present invention.

The flip-off type finishing cap 40 has a structure in which the fixed cap 40a and the separation cap 40b are integrally combined. 2, a cylindrical body 41 is inserted into the cap housing 12 so as to enclose the rubber cap 30 and the inner cap 20. As shown in FIG. A separation ring 43 is provided at the center of the upper surface of the fixed cap 40a. The separation ring 43 is supported by a plurality of connection ribs 42.

The separating cap 40b is provided with a coupling protrusion 44 for coupling the upper end of the cap housing 12 to the separating ring 43 at the center of the lower surface. Therefore, the fixing protrusion 44 is inserted into the separating ring 43, and the fixing cap 40a and the separating cap 40b are integrally combined by heating the end of the fitting protrusion 44. [

The inner cap 20 and the rubber stopper 30 are disposed on the cap housing 12 of the port body 10 and the separation cap 40b is removed while the finishing cap 40 is coupled to the inner cap 20 And the separation ring 43 is removed together with the separation cap 40b, so that the upper surface of the rubber stopper 30 is exposed.

Alternatively, the finishing cap 40 may be a so-called easy-peel film structure having a finishing film (not shown) directly attached on the fixing cap 40a. In this case, the fixing cap 40a does not need the rib 42 and the separating ring 43, and the spike can be inserted just by separating the finished film.

The drain port for the liquid bag according to the present invention is installed in the liquid bag in a state where the port body 10, the inner cap 20, the rubber cap 30, the fixed cap 40a and the separation cap 40b are in turn joined to each other . In order to drain the drug stored in the liquid bag, the separating cap 40b is removed to expose the upper surface of the rubber stopper 30.

In this state, when the spike is pushed into the concave groove 31a on the upper surface of the rubber stopper 30, the spike is applied to the spike penetration portion 31 of the rubber stopper 30 and the blocking film 21 of the inner cap 20 And then inserted into the lower holding tube 22. At this time, the spike penetration part 31 functions to restore the spike quickly without leaving a mark so that leakage does not occur after the spike is taken out while grasping the spike for the first time.

The blocking film 21 functions to securely block rubber spots from being generated in the rubber stoppers 30 while the spikes are being inserted while holding the spikes with a slight gap from the spike penetration portions 31 at a certain interval.

As described above, in the liquid-pouring bag drain port according to the present invention, since the spike penetration portion 31 and the shielding membrane 21 support the spike so as to overlap with each other with a slight gap, the thickness of the spike penetration portion 31 is somewhat The gripping force against the spike can be sufficiently exerted even if it is thin, and the spike can be easily inserted.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of the present invention is not limited by these embodiments. Those skilled in the art will appreciate that various modifications and changes may be made without departing from the spirit of the invention. However, it should be interpreted that these design changes are within the scope of the present invention unless new or unexpected effects are exhibited in the present invention.
