Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above conventional technology, the following problems remain. That is, in the technologies described in Patent Documents 1 to 3, basically, waste needles are stored horizontally, so the width of the needle disposal BOX is long and the whole becomes large, making it difficult to install on the bedside or the like. There was also the disadvantage that commercially available needle disposal BOXes are relatively expensive and result in high costs.

[0005] The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a disposable needle storage container that requires a small installation space, is safe, and has a low cost.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention adopts the following configuration. That is, a disposable needle storage container according to a first invention includes a bottomed outer cylindrical member formed of PET resin and having an opening at the upper part, and a bottomed inner cylindrical member formed of PET resin and insertable into the outer cylindrical member from the opening and having an inlet for disposable needles at the upper part.

[0007] In this disposable needle storage container, since it includes a bottomed outer cylindrical member formed of PET resin (polyethylene terephthalate) and having an opening at the upper part, and a bottomed inner cylindrical member formed of PET resin and insertable into the outer cylindrical member from the opening and having an inlet for disposable needles at the upper part, the disposable needles are basically stored vertically, so that the width of the disposable needle storage container itself can be narrowed. That is, a small installation space is sufficient, it is easy to install on the bedside or the like, and it is difficult to interfere with work or treatment. Therefore, after use, disposable needles can be directly stored in the disposable needle storage container installed on the bedside or the like, and there is no need to place them on a tray (such as a pus basin) once, so that the work of disinfecting and washing the tray (such as a pus basin) becomes unnecessary, and the work efficiency is improved.

[0008] In addition, the container has a double structure, and even if the disposable needles placed in the inner cylindrical member penetrate the inner cylindrical member, there is an outer cylindrical member, so it can be suppressed from penetrating to the outside, and it has high safety. Furthermore, only the inner cylindrical member can be removed from the outer cylindrical member, and the internal disposable needles can be easily discarded. Note that since both the outer cylindrical member and the inner cylindrical member are made of PET resin, they are light and strong, and can be recycled by crushing or decomposition.

[0009] The waste needle storage container according to the second invention is characterized in that, in the first invention, the insertion port has a plurality of slit portions radially extending outward from the axis of the inner cylindrical member in the radial direction. That is, in this waste needle storage container, since the insertion port has a plurality of slit portions radially extending outward from the axis of the inner cylindrical member in the radial direction, when inserting a waste needle into the insertion port, the insertion port expands due to the cuts by the plurality of radial slit portions, making it easier to insert the waste needle, and at the same time, it can be suppressed that the inserted waste needle slips out from the insertion port to the outside.

[0010] The waste needle storage container according to the third invention is characterized in that, in the first or second invention, the bottom of the inner cylindrical member is tapered such that the inner diameter gradually decreases downward. That is, in this waste needle storage container, since the bottom of the inner cylindrical member is tapered such that the inner diameter gradually decreases downward, the bottom of the inner cylindrical member tapers, and the tip of the waste needle inserted inside is directed toward the axis of the inner cylindrical member, and it can be suppressed that the tip of the waste needle protrudes from the peripheral wall of the inner cylindrical member to the outside.

[0011] The waste needle storage container according to the fourth invention is characterized in that, in the first or second invention, it is provided with a ring member attached to the peripheral surface of the outer cylindrical member. That is, in this waste needle storage container, since it is provided with a ring member attached to the peripheral surface of the outer cylindrical member, the waste needle storage container can be easily attached to a bed or the like through a rod member or the like standing on a bed or the like and passing through the ring member such as a card ring. Also, by hanging an S-shaped hook or the like on the ring member, it can be easily suspended and stored in various places such as a handrail. Furthermore, the waste needle storage container can be carried by holding the ring member, and it can be carried more easily and safely.

[0012] The waste needle storage container according to the fifth invention is, in the first or second invention, characterized in that the outer cylindrical member is formed by processing the bottom of a PET bottle having a cap at the upper part to form the opening, and the inner cylindrical member is formed by processing the bottom of a PET bottle having a cap at the upper part to form the insertion port. That is, in this waste needle storage container, since the outer cylindrical member is formed by processing the bottom of a PET bottle to form an opening, and the inner cylindrical member is formed by processing the bottom of a PET bottle to form an insertion port, used PET bottles and the like can be reused, and it is possible to manufacture them at low cost, thereby significantly reducing the cost. For example, when a 2.0L PET bottle is used as the outer cylindrical member and a 1.5L PET bottle is used as the inner cylindrical member, it is possible to store about 70 to 80 waste needles, which is more than that in a commercially available waste needle box. In this case, since there is a cap of the PET bottle at the bottom of the inner cylindrical member, it is also possible to discharge the stored waste needles by removing the cap from the bottom of the inner cylindrical member.

Advantages of the Invention

[0013] According to the present invention, the following effects can be obtained. That is, according to the waste needle storage container of the present invention, since it includes a bottomed outer cylindrical member formed of PET resin and having an opening at the upper part, and a bottomed inner cylindrical member formed of PET resin and having an insertion port for waste needles at the upper part and being insertable into the outer cylindrical member through the opening, the waste needles are basically stored vertically, so the width of the waste needle storage container itself can be narrowed, making it easier to install on the bedside or the like. At the same time, the container has a double structure and has high safety. In addition, since the outer cylindrical member and the inner cylindrical member are made of PET resin, they are light and strong, and it is possible to manufacture them at low cost using used PET bottles and the like. Therefore, the waste needle storage container of the present invention requires a small installation space, has high safety and low cost, and can achieve high working efficiency and cost reduction when disposing of used artificial dialysis puncture needles.

Modes for Carrying Out the Invention

[0015] Hereinafter, an embodiment of the waste needle storage container in the present invention will be described based on FIGS. 1 to 3. Note that in the drawings used in the following description, there are parts where the scale is appropriately changed as necessary in order to make each member recognizable or easily recognizable.

[0016] The waste needle storage container 1 in this embodiment includes, as shown in FIGS. 1 and 2, a bottomed outer cylindrical member 2 formed of PET resin (polyethylene terephthalate) and having an opening 2a at the upper part, and a bottomed inner cylindrical member 3 formed of PET resin and insertable into the outer cylindrical member 2 from the opening 2a and having an inlet 3a for waste needles N at the upper part.

[0017] The waste needle N is, for example, a used artificial dialysis puncture needle. As shown in FIG. 2, the inlet 3a has a plurality of slit portions 3b extending radially outward from the axis C of the inner cylindrical member 3. The bottom 3c of the inner cylindrical member 3 has a tapered shape in which the inner diameter gradually decreases downward.

[0018] Further, the waste needle storage container 1 in this embodiment includes a ring member 4 attached to the peripheral surface of the outer cylindrical member 2. The outer cylindrical member 2 is formed by cutting the bottom of a PET bottle having a cap at the upper part, turning it upside down, and forming an opening 2a at the upper part.

[0019] The inner cylindrical member 3 is formed by making holes and cuts in the bottom of a PET bottle having a cap at the top with an ultrasonic cutter or the like, and turning it upside down to form an inlet 3a having a radial slit portion 3b at the top. Since the outer cylindrical member 2 and the inner cylindrical member 3 are made by processing commercially available PET bottles, a cap 5 is detachably attached to the bottom.

[0020] For example, a 2.0L PET bottle is used for the outer cylindrical member 2, and a 1.5L PET bottle is used for the inner cylindrical member 3. As the PET bottle to be used, a transparent or translucent one through which the stored waste needle N can be visually recognized from the outside is preferable. The inner diameter B at the center of the inlet 3a is, for example, about 0.5 cm. The slit portions 3b of the inlet 3a are formed, for example, eight in number at equal intervals in the circumferential direction radially. The ring member 4 is, for example, a card ring inserted through two holes opened in the outer cylindrical member 2 and attached.

[0021] When storing the waste needle N, it is inserted into the upper inlet 3a of the inner cylindrical member 3 from the tip of the needle and put inside. A photograph of a state in which a plurality of waste needles N are inserted and stored in the actually produced waste needle storage container 1 is shown in FIG. 3. In this example, 75 to 80 waste needles N can be stored in the waste needle storage container 1.

[0022] Also, when discarding, it is possible to remove only the inner cylindrical member 3 storing the waste needle N from the outer cylindrical member 2 and discard it. Since a conventional commercially available needle disposal BOX is larger than the waste needle storage container 1 of the present embodiment, only 6 boxes can be stored in a 50L infectious waste container, whereas about 20 of the waste needle storage containers 1 of the present embodiment can be stored in a 50L infectious waste container.

[0023] Thus, in the waste needle storage container 1 of this embodiment, a bottomed outer cylindrical member 2 formed of PET resin (polyethylene terephthalate) and having an opening 2a at the upper part, and a bottomed inner cylindrical member 3 formed of PET resin and insertable into the outer cylindrical member 2 from the opening 2a and having an inlet 3a for the waste needle N at the upper part are provided. Since the waste needle N is basically stored vertically, the width of the waste needle storage container 1 itself can be narrowed.

[0024] That is, a small installation space is sufficient, it is easy to install on the bedside or the like, and it is difficult to interfere with work and treatment. Therefore, after use, the waste needle N can be directly stored in the waste needle storage container 1 installed on the bedside or the like, and there is no need to place it on a tray (such as a pus basin) once, so the work of disinfecting and washing the tray (such as a pus basin) becomes unnecessary, and the work efficiency is improved.

[0025] In addition, the container has a double structure. Even if the waste needle N placed in the inner cylindrical member 3 penetrates the inner cylindrical member 3, there is the outer cylindrical member 2, so it can be suppressed from penetrating to the outside, and it has high safety. Furthermore, only the inner cylindrical member 3 can be removed from the outer cylindrical member 2, and the internal waste needle N can be easily discarded. Since both the outer cylindrical member 2 and the inner cylindrical member 3 are made of PET resin, they are light and strong, and can be recycled by crushing and decomposition.

[0026] In addition, since the inlet 3a has a plurality of slit portions 3b extending radially outward from the axis C of the inner cylindrical member 3, when the waste needle N is inserted into the inlet 3a, the inlet 3a expands due to the cuts by the plurality of radial slit portions 3b, making it easier to insert the waste needle N, and at the same time, it can be suppressed that the inserted waste needle N slips out from the inlet 3a to the outside.

[0027] In addition, since the bottom 3c of the inner cylindrical member 3 is tapered such that the inner diameter gradually decreases downward, the bottom 3c of the inner cylindrical member 3 tapers, and the tip of the waste needle N placed inside is directed toward the axis C of the inner cylindrical member 3, suppressing the tip from protruding outside from the peripheral wall of the inner cylindrical member 3.

[0028] Further, since the waste needle storage container 1 is provided with a ring member 4 attached to the peripheral surface of the outer cylindrical member 2, the waste needle storage container 1 can be easily attached to a bed or the like through a rod member P or the like standing on the bed or the like on the ring member 4 such as a card ring. Also, by hooking an S-shaped hook or the like on the ring member 4, it becomes possible to easily hang and store it in various places such as a handrail. Furthermore, the waste needle storage container 1 can be carried by holding the ring member 4, and it can be carried more easily and safely.

[0029] Furthermore, since the outer cylindrical member 2 is formed by processing the bottom of a PET bottle to form the opening 2a, and the inner cylindrical member 3 is formed by processing the bottom of a PET bottle to form the inlet 3a, used PET bottles and the like can be reused, and it becomes possible to manufacture them at low cost, significantly reducing the cost.

[0030] For example, when a 2.0 L PET bottle is used as the outer cylindrical member 2 and a 1.50 L PET bottle is used as the inner cylindrical member 3, about 70 to 80 waste needles, which is more than a commercially available BOX for waste needles, can be stored. In this case, since there is a cap 5 of a PET bottle at the bottom of the inner cylindrical member 3, it is also possible to remove the cap 5 and discharge the stored waste needle N from the bottom of the inner cylindrical member 3.

[0031] Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
