Description

Medical electrode catheter sterilization container for waste medical and electrode catheter treatment method using the same {Contaioner for the waste electrophysiology catheter and treatment method using it}

The present invention relates to a container for sterilizing and collecting the finished medical electrode catheter and a method of treating the catheter using the same.

A catheter is a thin tubular medical device and is widely used for discharge of debris in the body, suction of washing perfusion liquid, injection of a drug, or measurement of a bioelectric signal. The catheter is made of soft or hard, and depending on the purpose of use, it may have a structure that can inflate the insertion end like a balloon, or may be made of two tours, and may be made to have various characteristics such as soft or hard in terms of flexibility.

Typically, the electrode catheter is made of stainless steel, copper wire core material is wrapped in polyurethane as a base material, the electrode exposed to the outside is used a platinum alloy excellent in conductivity and corrosion resistance.

Since such an electrode catheter is used in a living body, it is treated as a hospital waste in its entirety and incinerated. As a result, precious metals such as platinum used in the electrode catheter are discarded as they are, and there is a waste of precious metals such as platinum.

Electrode catheter used for medical use has a high possibility of infection, such as the retention of living organisms. Therefore, there is a risk of infection even if you try to collect it. If the treatment of such disinfection is not carried out reliably, there is a fear that secondary infection may occur during the post-treatment process.

The present invention has been made to solve the above-described problems, and has the object of ensuring safe disinfection during collection of the closed electrode catheter. It also has the purpose of providing a disinfection treatment method so that there is no fear of secondary infection. It also has the purpose of recovering valuable noble metals from the waste electrode catheter.

In order to solve the above problems, the present invention is an embodiment, the sterilizing agent may be contained therein, a container body having an open spout is formed, and is detachably coupled to the spout, and is formed by being recessed from an upper surface thereof. And a stopper having a mounting groove having a through hole formed therein, and being inserted into and fixed in the mounting groove, the opening hole is closed to be open, and a closed electrode catheter sterilizer including a cap portion into which the electrode catheter can be inserted in the longitudinal direction thereof. Present the collection container.

Herein, the cap part is an empty polyhedron, and the cap part is formed by cutting the lower surface of the cap part, and is elastically deformed and opened by the electrode catheter to open the passage hole, and is restored to block the passage hole. The reinforcing part may include a through hole formed in the ceiling of the cap part and a reinforcement part formed between the inner circumferential surface of the through hole and the inner wall surface of the cap part to reinforce the periphery of the through hole.

In addition, the stopper may include a door piece for closing the mounting groove to be openable.

In addition, the door piece may be rotatably connected at one side of the stopper, and a protrusion may be formed to be inserted into the through hole and detachably fitted to the through hole.

In addition, the periphery of the stopper protrudes upward to form a circumferential wall, and the door piece may be further formed with a grip ring.

On the other hand, by using a waste electrode catheter sterilization container, the first step of sterilizing the waste electrode catheter used in the electrode catheter sterilization container containing a reducing-type disinfectant drug, open the stopper of the electrode catheter sterilization container, sterilization Separating the drug and the waste electrode catheter by using a hooking network, immersing the separated waste electrode catheter in a chlorine disinfectant to secondary sterilization, and the third sterilization and drying by irradiating ultraviolet light after the second sterilization A treatment method of a pulmonary electrode catheter is included.

Furthermore, the method may further include grinding the dried waste electrode catheter, and extracting a platinum group element from the ground electrode catheter.

According to the embodiment of the present invention, it is possible to safely disinfect pathogens present in the pulmonary electrode catheter during the collection process of the pulmonary electrode catheter, thereby eliminating all problems such as secondary infection. In addition, since the sealing performance is improved by the cap and the cap part, it also has the effect of reliably preventing the leakage of the disinfectant. In addition, since the precious metal can be extracted from the electrode catheter, the recycling rate for the rare metal is also increased.

Hereinafter, with reference to the accompanying drawings will be described the configuration, function and operation of the waste electrode catheter sterilization container and electrode catheter treatment method using the same. However, in the embodiments, reference numbers for similar or identical components are used uniformly.

1 to 3, the waste electrode catheter sterilization container 10 according to the embodiment of the present invention includes a container body 1, a stopper 2, and a cap 3.

The container body 1 may contain a disinfectant drug therein, and an open spout 11 is formed. The container body 1 is formed of synthetic resin, the handle 12 is formed on one side of the upper surface, the spout 11 is formed with the stopper 2 is coupled to the other side of the upper surface. The snout has a cylindrical shape, and a thread 111 is formed on the outer circumferential surface thereof.

The stopper 2 is detachably coupled to the spout 11. On the inner circumferential surface of the stopper 2, a thread 2b screwed to the thread 111 of the spout 11 is formed. The stopper may be molded of synthetic resin like the container body.

In addition, the sealing material 4 is engaged with the inner upper surface of the stopper 2. The sealing material 4 is interposed between the upper end of the spout 11 and the inner upper surface of the stopper 2 to prevent the contents of the container body 1 from leaking to the outside. In addition, the gas evaporated from the sterilizing agent stored inside the container body will not leak to the outside.

The part of the sealing material 4 which contacts the upper end of the snout protrudes convexly. The sealing material 4 is made of an elastic silicone material, and when the stopper is coupled to the spout, when the spout protrudes convexly, the elastic deformation is performed. Such elastic deformation enables the sealing material to fill the gap between the spout and the stopper without gap, thereby preventing the leakage of the sterilizing agent or its gas, etc. more reliably.

On the other hand, the center part of the upper surface 2a of the stopper 2 is recessed to form the mounting groove 21. The position of the mounting groove may be formed to be biased toward one side from the top surface of the stopper.

The through hole 211 is formed in the bottom surface of the mounting groove 21. Since the diameter of the passage hole 211 is smaller than the inner diameter of the mounting groove 21, the stepped 212 is formed on the bottom surface of the mounting groove 21.

In addition, the periphery of the mounting groove 21 of the plug 2 is recessed to form the coupling groove 23. The coupling groove 23 extends from the upper surface of the plug 2 toward one edge. A door piece 24 is provided at one side of the edge of the stopper 2 that meets the engaging groove 23. As the connecting portion of the door piece 24 and the stopper 2 is formed to be thin, the door piece 24 is rotatable on one side of the stopper 2. In addition, the door piece 24 can be fitted into the coupling groove 23, so that the open mounting groove 21 can be detachably blocked. Such door pieces can be omitted.

The cap 3 is coupled to the mounting groove 21. Cap portion 3 is made of an elastic material. For example, synthetic rubber, silicone, etc. may be used as the elastic material.

The cap 3 is normally closed to prevent the contents of the container body 1 from flowing out, and can be opened when the electrode catheter is inserted in its longitudinal direction.

In FIG. 3, the cap part 3 is a cylindrical body empty inside. The outer shape of this cap portion 3 depends on the shape of the mounting groove. The outer surface of the cap portion can be firmly fixed to the mounting groove with an adhesive. Alternatively, although not shown, a coupling jaw protruding inwardly may be formed at an open upper end of the mounting groove, and the upper circumference of the cap may be caught by the coupling jaw, so that it may be mounted in the mounting groove.

The empty inner space 31 of the cap 3 becomes a space through which the electrode catheter passes. The cross-sectional area of the inner space is therefore at least equal to or greater than the electrode catheter. However, it is advantageous that the cross-sectional area of the inner space 31 is larger than the cross-sectional area of the electrode catheter so as to enable smooth folding of the cut piece 32 to be described later.

In addition, a through hole 32 through which the electrode catheter passes is formed in the ceiling surface 3a of the cap 3. Between the ceiling surface 3a and the inner side surface 3b in which the through hole 32 was formed, the reinforcement part 33 which increases the intensity | strength of the periphery of the through hole 32 is further formed. The reinforcement part 33 may be made of an additional tooth filling the space between the ceiling surface 3a and the inner surface 3b, or may be formed of a rib or the like. Since the thickness of the upper and lower periphery increases by the reinforcement part, the periphery of the through hole decreases in elasticity, thereby increasing structural rigidity.

On the other hand, the cut piece 32 which can be opened by the electrode catheter which enters is formed in the lower surface of the cap part 3. As shown in FIG. That is, the cutting piece 32 may be formed by cutting the lower surface of the cap 3, and may be elastically deformed and opened by the electrode catheter to open the passage hole 211. In addition, the cut piece 32 is normally restored to its original position to block the passage hole 211.

In FIG. 3, an incision piece 32 having a lower surface divided by a single incision line 321 passing through a center from a circular lower surface of an inner space is illustrated. Such a cut piece may be formed by dividing a plurality of lower surfaces according to a plurality of cut lines. Alternatively, the remaining peripheral portion may be formed by cutting off a portion of the lower surface connected to the inner surface.

In addition, the edge of the lower surface forms an extension portion 34 which protrudes further downward to reinforce the cut piece 32, as the inner peripheral surface extends. Since the incision piece 32 is formed by the extension part 34 in the intermediate part instead of the end part of the inner surface 3b, the connection part with the inner surface 3b does not tear easily even by repeated elastic deformation. Done. In addition, the protruding extension 34 is spaced apart between the cut piece 32 and the step 212 against the step 212 inside the mounting groove (see FIG. 5). Thereby, the clearance space which elastically deforms a cut piece is ensured, and the elastic deformation of a smoothly cut piece is attained.

Referring to FIGS. 2 and 4 again, the door piece 24 further includes a protrusion 241 protruding from the through hole 32 of the cap 3 installed in the mounting groove 21. When the door piece 24 is fitted into the engaging groove 23, the projection 241 is detachably fitted into the through hole 32.

At this time, the protruding end portion 241a of the protrusion 241 is rounded in a substantially hemispherical shape, and the outer circumferential surface is formed in a narrow shape. The outer diameter of the hemispherical end portion 241a is larger than the inner diameter of the through hole 32, so that the end portion 241a of the protrusion 241 is inserted into the through hole 32 while opening the inner diameter of the through hole 32 further. . When the end passes, the through hole grips the outer circumferential surface of the narrow protrusion by the restoring force.

The fitting coupling force of the door piece can be made larger by the fitting coupling of the cap part and the protrusion. In addition, even if the sterilization container falls down and the sterilizing solution leaks through the incision line of the incision, the leakage of the sterilizing agent is more reliably prevented because the projection is blocked.

5 shows a state of use of the waste electrode catheter sterilization container according to an embodiment of the present invention.

The door piece 24 of the stopper 2 is opened, and the electrode catheter C is pushed into the container body through the through hole 32 along the longitudinal direction of the long electrode catheter C. As shown in FIG. At this time, the front end of the electrode catheter (C) passing through the cap portion 3 is pressed down the incision piece 32, whereby the incision piece 32 is elastically deformed downward as shown and The lower surface is opened to allow the electrode catheter C to pass. Thereafter, the rear end of the electrode catheter passes through the incision piece by the weight of the electrode catheter already entered into the container body, and the incision piece is restored to close the lower surface of the cap part.

Figure 6 shows a stopper (2) of the waste electrode catheter sterilization container according to another embodiment of the present invention. Sterilization container according to another embodiment of the present invention may have the features according to Figs. 1 to 5 as long as it does not violate as described below. According to another embodiment of the present invention, the periphery of the plug 2 protrudes upward to form a circumferential wall 242, and the door piece 24 is further provided with a grippable ring 243.

Specifically, the top edge of the stopper 2 further protrudes upward to form the circumferential wall 242. The upper surface 2a of the stopper 2 is recessed by the circumferential wall 242.

In addition, the door piece 24 is hingedly coupled to one upper end of the circumferential wall 242. When the door piece 24 is coupled to the upper portion of the stopper 2, one portion 24a coupled to the fitting groove 242a recessed at one side of the circumferential wall 242, and the coupling recessed in the upper surface of the stopper It can be divided into two portions 24b that are coupled to the grooves 23. A handle ring 243 is formed on the other side opposite to one surface of the two portions 24b that contacts the stopper 2. The ring 243 may be a loop that is integrally formed with the two parts 24b as shown, or may have various shapes that are easily pulled by a user using a finger or the like.

At this time, when the door piece 24 is coupled with the stopper 2, the protruding height of the ring 243 is equal to or lower than the protruding height of the circumferential wall 242. Therefore, it is possible to more reliably prevent opening of the door piece against the user's intention in handling, such as movement, storage, etc. of the sterilization container.

Components such as protrusions provided on the door pieces and caps provided on the caps are the same as in the above-described embodiments, and thus redundant descriptions thereof will be omitted.

7 sequentially shows a method of treating a closed electrode catheter according to an embodiment of the present invention.

According to an embodiment of the present invention, by using the waste electrode catheter sterilization container as described above, the first sterilization by putting the waste electrode catheter used in the electrode catheter sterilization container containing a reducing-type sterilizing agent (s1) , The second electrode is sterilized by immersing the separated waste electrode catheter in a chlorine disinfectant (s2) and the third step of sterilization and drying by irradiating ultraviolet light after the second sterilization (s3).

At this time, between the first sterilization step (s1) and the second sterilization step (s2), by opening the stopper of the electrode catheter sterilization container after the first sterilization, using a sterilizing agent and a waste electrode catheter using a catching network It may further comprise the step of separating.

In addition, the method may further include extracting the platinum group element from the electrode catheter after tertiary sterilization and drying (s4). In this case, the method may further include grinding the dried waste electrode catheter before the step of extracting the white metal element.

First, the first sterilization step (s1) comprises a reducing-type bactericidal agent in the electrode catheter sterilization container, and accommodates the electrode catheter.

Here, the reducing agent disinfectant may include formaldehyde, glutaraldehyde, sulfur dioxide, and the like.

A 40% aqueous solution of formaldehyde is generally called formalin, and is known to exert an antiseptic effect by binding to amino groups on the surface of bacterial cells.

On the other hand, glutaraldehyde has lower irritation to skin and mucous membranes than formaldehyde. Susceptible to a wide range of pathogenic microorganisms. In particular, since the bactericidal power is maintained even in the presence of blood components such as serum, it is suitable for the use of electrode catheters, which are used inside a living body and contain a residue containing protein components.

The sterilization container is placed in the waste storage of hospitals and stores the electrode catheter imported from the operating room. The electrode catheter submerged in the sterilizing agent of the sterilization container is first sterilized by the sterilizing agent until the sterilization container is recovered (s1).

Thereafter, the sterilization container is collected together, and after opening the stopper, the sterilizing agent and the waste electrode catheter are poured onto the hook network to separate the waste electrode catheter and the sterilizing agent. The separated sterilizing agent is collected in a wastewater treatment tank, and secondary electrode sterilization is performed by collecting waste electrode catheter from a strainer and immersing it in a chlorine disinfectant (s2).

Here, the chlorine disinfectant uses the strong oxidizing power of the chlorine agent. For example, chlorine disinfectants include sodium hypochlorite, chlorinated lime, or chloramines such as sodium dichloroisocyanurate. They generate bactericidal non-hypochlorous acid (HClO). In particular, the use of pulsating nodol is effective for the virus and apo, and is suitable for secondary disinfection of the electrode catheter. This secondary disinfection is accomplished by immersing the electrode catheter for a period of at least 30 minutes or longer.

After the second sterilization treatment, the electrode catheter is put into an ultraviolet dryer (not shown), and the third sterilization and drying are simultaneously performed by ultraviolet light irradiated by the ultraviolet lamp. At this time, in order to promote drying, the temperature inside the ultraviolet dryer may be raised.

Meanwhile, the step of extracting the platinum group element from the dried electrode catheter may be further performed. The extraction of the white metal element may be made through various well-known methods such as wet extraction or dry extraction. At this time, the wet extraction is to deposit a dry electrode catheter or a pulverized electrode catheter in aqua regia to dissolve the platinum group element to extract in the form of chloride. Wet extraction has the advantage of low platinum loss.

On the other hand, dry extraction is a slag by melting the waste electrode catheter in a plasma furnace or an arc furnace, and the platinum group element is collected in a crude metal state and then refined by a wet method.

Unlike conventional catalysts for automobile exhaust gas, the waste electrode catheter has a high content ratio, and thus economical efficiency is good even by dry extraction.

The catheter contained in the sterilization container according to an embodiment of the present invention is applicable to various kinds of catheters in addition to the above-described electrode catheter, and should not be interpreted as being limited in scope by the type of catheter.
