Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for treating a used injection needle for medical use, and is used for a syringe or a winged needle for drip which is used by being fitted or screwed to a tip portion of a holder. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing device for removing unnecessary needles from a holder and discarding the needles after use, and more particularly to a device of a type in which needles are burnt out for processing.

[0002]

2. Description of the Related Art Up to now, injection needles have been widely used for various business fields such as medical use and experimental research, and industrial sewing needles and general sewing needles have been used for sewing. When disposing of these needles, most of them are collected without being specially processed, and a disposal company directly disposes them in a cardboard box, bag, or the like, disposes of them at a special disposal site, and is landfilled as industrial waste. Many of them are mixed with general waste and discarded without any safe processing, which is a big social problem.

Disposable injection needles are widely used and used in large quantities in syringes for safety reasons, and as a result, a large amount of injection needle dust is generated, and safety measures are not thoroughly implemented. As a result, there is no doubt about the accident of injury, such as a processor accidentally sticking it in a finger during disposal. This accident may lead to serious accidents such as hepatitis B and C viruses adhering to the needle, blood infection due to AIDS, etc. Therefore, it is instructed to be careful when disposing. As a safety measure for its disposal, a bulky but non-stick syringe holder part and a dangerous injection needle are separated, and in particular, only the injection needle is thoroughly managed and safely disposed. As this separation method, there are a method in which a nurse pulls it out with fingers, and a method in which it is mechanically separated by using a processing tool.

In the former case, it is unavoidable to slip the hand and pierce the finger during processing, or to stab the foot or the like, and at that point it is more dangerous than in the case where nothing is processed. It was very good. In the latter case, as a simple matter, a guide hole is provided in the box body, the hole is formed so that the connection base portion of the injection needle can be hooked, and the device to be hung on the removal hole and removed is the actual open flat plate 3-88548. At the beginning, many proposals are provided. This type that is simply inserted into the removal hole and removed can be used for the type in which the injection needle is fitted in the syringe holder, but the type that is screwed cannot be removed by just trying to pull it out. I couldn't use it.

Therefore, the base of the injection needle is formed so as to be pressed in the removal hole so that the holder can be removed by screwing, and the holder can be manually rotated to remove it (JP-A-1-31066).
9) was proposed. However, even if it seems easy to rotate the holder one by one, it is a complicated task if it is done. Then, as a further improvement of the method, there is proposed a method (Japanese Patent Laid-Open No. 3-76) in which the base of the injection needle is rotated and removed by power while holding the holder. However, although the needle tip can be easily removed by the above method, the needle tip itself is still sharp and pointed, and therefore, it is still impossible to prevent the injury accident of being stuck in a finger or the like during the disposal process. In addition, a device (actual flat opening 2-111448) for mechanically bending and pulling out the needle tip has been proposed. In the case of this treatment, although the linear puncture due to the bending of the needle can be reduced, most needle tips remain sharp and pointed out, so it is not possible to eliminate injury accidents such as puncturing a finger.

For this reason, there has been proposed an injection needle processing apparatus of the type in which the needle tip is burnt off for processing, as proposed in Japanese Patent Laid-Open No. 60-5155. At this point, it became possible to prevent injury accidents. However, this device has many problems as follows. (1) The screwing type screwing cannot be performed. (2) Processing cannot be performed with only one hand. (3) Since the used portion of the electrode is always at the same position, the melted material that is melted and deformed at the electrode is apt to stick to the needle tip, and when the melted material is attempted to be withdrawn, the melted material does not catch on the electrode or the electrode is damaged. (4) The molten material solidifies and adheres to the electrodes and the current flow is hindered, so that the electrodes cannot be burnt out. (5) It is difficult to insert the needle tip into the electrode. As described above in (1) to (5), there are many drawbacks, and since they are extremely difficult to use, they have not been widely used until now.

[0007]

[0013]

Since the present invention has the above-described structure, when the needle S is burned out in the needle burning mechanism 2, the temperature rises to about 800 ° C. and the tip T of the needle S is melted and simultaneously sterilized. Therefore, the needle is less likely to be stabbed, and even if it is stabbed, it is sterilized so that infection with a virus or the like does not occur. While the nurse holds the syringe holder-H part, first, the needle S is burned off by the needle burning mechanism 2, and then the needle S is guided to the needle dropping mechanism 3 to separate and drop the needle S from the holder-H. Can be done continuously with one hand. This processing operation can be performed on all types of injection needles having different shapes.
That is, in the case of the needle tip screwing type, the needle dropping mechanism 3 for rotating is used, in the case of the fitting type, the fitting type needle dropping mechanism 23 is used, and in the case of the winged needle, the needle tip insertion guide 1
6 can be inserted into the insertion guide hole 34 and processed. In addition,
Even when the needle tip insertion guide 16 is removed, since the fixed electrode 8 and the open / close electrode 9 of the upper electrode 7 have the same polarity, there is no danger of electric shock and it is safe to touch with a finger. When burned out, the winged needle is put into the hole 26.

Further, unlike the conventional one point insertion type electrode, the electrode portion of the present invention has a long parallel electrode and melts the needle contact point while sliding the slanted surface 11 so that the melted material is a needle tip. There is no possibility of damaging the electrode because the melted material is not scraped off from the electrode and the melted material does not get caught in the electrode or come off. Further, since the melt does not adhere to the electrodes, normal energization is ensured. Further, since the electrode S is moved while moving the electrode contact point from the tip T of the needle S toward the base, the range S from the tip T to the base can be dissolved. When the needle S is inserted into the electrode, it is guided by the needle tip insertion guide 16 so that it can be reliably set in the electrode even if the needle is roughly inserted. Furthermore, since one of the upper electrodes 7 is the open / close electrode 9, the holder-H Can be easily inserted into the groove 30 of the upper electrode 7 with a margin even if it is slightly inclined.

[0015]

[Usage] When using the present invention, a power source is required,
The battery 35 is charged in advance for carrying around. The process after the use of the syringe is holder-H
The portion to be used is selected according to the form of the connecting base portion K between the needle S and the needle S. In the case of the screw-on type, while the nurse holds the syringe holder-H part, first insert the needle tip into the needle tip insertion guide 16 as shown in FIG. 8, and further as shown in FIGS. 4 and 5. Then, the needle S is burnt out while moving it while pushing it down along the insertion guide groove 17. When inserting the needle tip,
Since it is guided by the needle tip insertion guide 16, it can be set securely even if the needle tip is roughly inserted, and even if the holder-H is slightly displaced or tilted by the opening / closing electrode 9, there is a margin between the fixed electrode 8 and the opening / closing electrode 9. Can be inserted into. Next, FIG.
As shown in FIG. 10, the needle connecting base K is placed on the needle guiding groove 4a and passed therethrough, and is guided to the needle dropping mechanism 3 shown in FIG. 10 as it is to press the needle connecting base K of the holder-H against the drive switch plate 21. Then, the connecting base K of the needle S rotates and comes out of the holder-H. Then, if it is slightly backed from the holding portion 19 and returned to the wide introduction groove 18, it falls into the fall needle storage portion 5 through the drop hole 31 therebelow. All of these steps can be continuously performed with one hand while holding the holder-H.

In the case of the fitting type, the steps S are the same as in the case of the screwing type until the needle S is burnt out. Then, as shown in FIG. 9, when the needle S is inserted into the stop groove 24 of the fitting-type needle drop-off mechanism 23, the needle S is held by the inclined surfaces 25 on both sides thereof.
It is pushed away from H and falls out. In the case of a winged needle, the needle tip insertion guide 16 is replaced by the winged needle needle tip insertion guide 37.
By replacing the needle with the wing portion, the needle can be directly inserted between the fixed electrode 8 and the opening / closing electrode 9 of the upper electrode 7 and sufficiently burned. At the time of replacement, even if the fixed electrode 8 and the open / close electrode 9 are exposed, since they have the same polarity, there is no danger of electric shock even if a finger touches them, and it is safe. When it is burnt out, it is pulled out and inserted into the winged needle insertion hole 26 shown in FIG. When the burned-out needles are collected in the falling needle storage portion 5, the needles are put in another container or the like and discarded.

As shown in FIG. 2, inside the housing 1, a needle burnout mechanism 2, a needle drop-off mechanism 3 and a needle guiding mechanism 4 between them are integrally housed in the upper portion of the housing 1. In addition, a drop needle storage portion 5 is provided in the lower portion inside the housing 1. Further, the surplus space at the rear of the housing 1 is provided with a power supply means 6 such as a battery-35 for supplying electric power to the electrodes of the needle burnout mechanism 2 and the drive means 20 of the needle dropout mechanism 3. Then, the burnout of the needle S and the separation and detachment from the holder-H can be continuously performed in the order of the needle burnout mechanism 2, the needle guiding mechanism 4, and the needle detachment mechanism 3.

The mechanism of each of the above-mentioned structures will be described in detail below. The needle burn-out mechanism 2 is composed of an upper electrode 7 and a lower electrode 10 which form a pair and are separated from each other, as shown in FIGS. 6 and 7. . The upper electrode 7 includes a fixed electrode 8 and an opening / closing electrode 9 having a parallel length of 30 mm and the same polarity. The lower electrode 10 has a length of 30 mm below the upper electrode 7.
An inclined surface 11 having a width of mm and an inclination of 45 degrees is made to face the fixed electrode 8. Further, in the fixed electrode 8, the tip electrode portion 12 of the electrode fixing plate 13 whose position is fixed is formed on the lower slope 14 having an inclination of 45 degrees, and the open / close electrode 9 has its tip edge 9a at the tip of the fixed electrode 8. A leaf spring 15 having a U-shaped cross section is urged so as to return to the position directly above with a distance of 3 mm from the edge 8a.

The needle S inserted in the deepest upper part 17a of the insertion guide groove 17 is pushed downward, and as shown in FIG. 5, the needle tip T abuts on the inclined surface 11 of the lower electrode 10, and this contact causes the contact. The upper electrode 7 and the lower electrode 10, which are already sandwiched and are in contact with each other and connected, are energized and heated, and the needle tip T is melted. Further, when the holder-H is continuously pressed downward by hand, the needle tip T is melted and shortened, and the connecting base K is placed on the slope of the insertion guide groove 17 and is pushed down the slope to lower the needle tip T. It reaches the end 17b of the insertion guide groove 17 while melting. During this time, the contact point between the upper electrode 7 and the lower electrode 10 is
Instead of being fixed at one point, it moves widely in one direction (arrow direction) as shown in FIG. At the same time, the molten residue of the needle does not adhere to the lower electrode 10 and the inclined surface 1
Drop 1 naturally. For this reason, normal energization is ensured without the needle tip coming off the electrode or damaging the electrode itself.

The needle tip insertion guide 16 is provided on the upper surface 1 of the housing 1.
It is possible to attach / detach and slide by using a fitting frame 27 (shown in (a) of FIG. 3) or a slide frame (not shown) provided on the upper surface of the a or the needle burnout mechanism 2. Remove the needle tip insertion guide 16 and remove the fixed electrode 8 as shown in FIG.
By exposing the open / close electrode 9 and the open / close electrode 9, the winged needle Y without the connecting base K is directly inserted, or as shown in FIG. 4B, the winged needle insertion hole 34 is formed in the bottom of the substantially mortar-shaped recess. It is possible to mount the provided winged needle needle tip insertion guide 37, and to mount the insertion guide 37 on the fitting frame 27 provided on the top surface of the housing 1 or the top surface of the needle burnout mechanism 2 for processing. Separately, a slide frame (not shown) is provided, and the needle tip insertion guide 16
It is also possible to perform the processing by shifting the position on the groove 30 by sliding it side by side in parallel with. In addition, as shown in FIG. 3, both ends of the insertion guide groove 17 are removed so that both corners of the insertion guide groove 17 are outwardly opened. End 1 of 17
If both ends of the corners 8b and 9b are formed so as to be opened outward like 7c, as shown in FIG. 8, when the needle tip is inserted and set between the fixed electrode 8 and the open / close electrode 9, the holder-H The needle S can be smoothly attached even if the needle S is slightly deviated from the center position of the groove 30 or is inclined.

Next, the needle drop-off mechanism 3 will be described. As shown in FIGS. 2, 3 and 10, the introduction groove 18 for introducing the needle S burned by the needle burning-off mechanism 2 and the needle S introduced. And a holding portion 19 for holding the connecting base portion K. Adjacent to this, a motor 28 for rotating the holding portion 19 via a transmission mechanism 20a is provided. A drive switch plate 21 that comes into contact with and reacts with the abutting portion of the holding portion 19 is provided in the holding portion 19 with its tip portion forwardly biased. Then, when the connecting base K of the holder H hits the drive switch plate 21, the switch is pushed to be turned on, the drive motor 28 rotates, and the sandwiching portion 19 rotates in the screwing out direction. At this time, the holder-H is held in the hand and does not rotate, and the holder-H is pushed up. Then, the holder-H is disengaged from the connecting base K, and the switch plate 21 moves forward. Then, the switch turns off and the rotation stops.

When a back stopper rubber sheet (not shown) which hangs on the needle tip is hung below the inlet port 18a of the inlet groove 18, the holder H is retracted from the inlet groove 18 after the rotation is stopped. A mode is possible in which the needle tip is caught by this rubber sheet and is surely released from the holder H and dropped. Then, the needle guiding mechanism 4 linearly communicates the groove 30 of the needle burnout mechanism 2 and the introduction groove 18 of the needle dropping mechanism 3, and slides with the needle connecting base K placed as shown in FIG. The possible guiding groove 4a is formed.

Further, as shown in FIGS. 8, 9 and 11, the fitting type needle drop is exclusively for the needle which is communicated with the groove 30 of the needle burnout mechanism 2 and is fitted into the holder H to be connected. The removing mechanism 23 is provided next to the device. This mechanism 23 is wider than the diameter of the tip of the holder-H to which the connecting base K is fitted, and the collar U of the connecting base K.
On both sides of the narrower stop groove 24, inclined surfaces 25 that gradually increase in the depth direction are formed. Then, as the connecting base K advances into the depth of the stop groove 24, the holder H and the brim U are expanded, and the connecting base K separates from the holder H and falls off in the middle thereof.

According to the present invention, the needle S is burned by the needle burning mechanism 2 so that the needle is sterilized at a high temperature, which makes it difficult for the worker to pierce the needle during the disposal process. It is extremely safe because it does not cause infection. If the nurse carries it with him / her during work, all of the injection needles of different forms can be processed on the spot. In particular, while holding the syringe holder-H part, first, the needle S is burned by the needle burning mechanism 2, and then the needle S is guided to the needle dropping mechanism 3 as it is to drop the needle S, and a series of these operations is continued with one hand. It can be completed quickly and easily.

In addition, the parallel upper electrode 7 and lower electrode 10
In addition, since it burns while moving the needle, it has become possible to maintain the burnout function for a long period of time. Furthermore, since most of the needles S are melted by the needle burnout mechanism 2, the needle S does not become bulky when discarded. For example, when the processing needles are packed in a container, it is possible to significantly reduce the volume of dust by 60% or more as compared with the case where the processing needles are not processed.
