Description

The present invention relates to a syringe disposal box that houses a used syringe. The syringe disposal box can be used to carry used syringes to the disposal site.

When a medical worker such as a doctor or a nurse disposes of a used syringe in a medical field such as a hospital, the medical worker accidentally stabs the needle of the used syringe into the hand or arm of himself or another person. An accident (needlestick accident) may occur. Needlestick injuries can cause the development of various infectious diseases.

In general, before putting a used syringe in the disposal box, a penetrating plastic cap is put on the needle to prevent the needle from being exposed, which is a countermeasure against needle stick accidents. .. However, needle stick accidents may occur when the plastic cap is placed over the needle of a used syringe.

Even medical professionals who usually come into contact with medical practice will have needlestick accidents with used syringes, but it is even more so when general patients who are not medical professionals perform treatment using syringes themselves at home etc. There is a risk of needle stick accidents.

For the treatment of psoriasis, a psoriasis patient may inject a syringe (subcutaneous injection syringe with an injection needle) containing a psoriasis therapeutic agent solution into the thigh or upper arm by himself / herself at home or the like. In order to dispose of a used syringe, the patient cannot dispose of it as garbage at home, but must carry the used syringe to a predetermined disposal site such as a medical institution and dispose of it. It is necessary to transport the used syringe in some container, but there is a risk of needle stick accident when the used syringe is stored in the container or when the container is transported to a medical institution. Similarly, needlestick accidents may occur in diabetic patients who inject insulin at home.

Patent Document 1 describes installation or portable medical care that can safely dispose of sharp medical waste such as syringes after use in order to prevent needle stick accidents caused by used syringes during home care at medical sites or home-visit care. The waste container is disclosed. The medical waste container is a container provided with a sealable main body for accommodating a used syringe and a needle stab body contained in the main body for piercing and locking the injection needle of the syringe. .. By using the medical waste container, the medical staff and the patient do not need to put a cap on the needle of the used syringe, so that the occurrence of needle stick accident that occurs when the needle is put on the cap is reduced.

Patent Document 2 discloses a syringe disposal container capable of stably accommodating a used pen-type syringe. The waste container includes a container body and a lid to be fitted to the container body, and the lid has a plurality of insertion holes sized to allow a syringe to be inserted, and a stopper for holding the syringe inseparably. A part is provided. The entire used syringe is inserted into the container body through the insertion hole, and is fixed so as not to come off at the retaining portion. By using the waste container, the pen-type syringe to be discarded is stably housed.

It can be done easily. The slide lock mechanism 14 may be provided at one place on the front surface of the syringe disposal box 10, or may be provided at a plurality of places or more.

As shown in FIG. 1 (b), the inside of the main body 11 is divided into a plurality of compartments 30, and a storage portion 20 for accommodating a used syringe is attached to each compartment 30. Each compartment 30 is configured to accommodate the containment section 20 and the syringes housed in the containment section 20. The size of each compartment 30 in the front-rear direction will be described in detail later, but the syringe cannot be taken out from the storage unit 20 while the storage unit 20 containing the syringe is suspended from the main body 11. There is no space between the syringe pusher (plunger) and the inner wall of the compartment 30 on the open end side of the containment 20 to allow the used syringe to be removed.

Each section 30 of the main body 11 is formed in a convex shape including a narrow portion 30A and a wide portion 30B in a plan view. The width w1 of the narrow portion 30A is larger than the width w2 of the accommodating portion 20, and the width w3 of the wide portion 30B is larger than the width w1 of the narrow portion 30A. By providing the wide portion 30B in the compartment 30, it becomes easy for the user to put a finger in the compartment 30 when lifting the open end of the accommodating portion 20, and it becomes easy to operate.

The compartments 30 are provided so that the positions of the wide portions 30B alternate in the front-rear direction so that the wide portions 30B of the adjacent compartments 30 are not adjacent to each other. With this configuration, it is possible to use the space in the main body 11 without waste while providing the wide portion 30B, and it is possible to accommodate a larger number of used syringes. The number of compartments 30 may be appropriately adjusted in consideration of the size of the syringe disposal box 10, the shape of the syringe, the frequency of use of the syringe, the frequency of transportation to the disposal site, and the like. The number of compartments 30 is not limited, but is 1 to 10, preferably 2 to 8, and more preferably 4 to 6.

FIG. 4 is a cross-sectional view taken along the line AA of the syringe disposal box 10 with the lid 12 closed, cut along the line AA shown in FIGS. 1B and 2A. 5 (a) is a sectional view taken along line AA of the syringe disposal box 10 in a state where the lid 12 is opened and the open end side of the accommodating portion 20 is lifted to the maximum, and FIG. 5 (b) is a cross-sectional view taken along the line AA. A sectional view taken along line AA of the syringe disposal box 10 in which the syringe 40 is housed in the storage unit 20 is shown.

The accommodating portion 20 is formed in a tubular shape (square cylinder or cylinder or a combination thereof), one end is open (open end 21A), and the other end is closed (closed end 21C). .. The hollow portion 21B inside the accommodating portion 20 is configured to accommodate the used syringe 40 with the injection needle facing the closed end 20C side. The hollow portion 21B of the accommodating portion 20 is configured to cover at least the injection needle and the needle base portion of the syringe 40. Further, in the accommodating portion 20, when the syringe 40 is inserted to the innermost part on the closed end side of the accommodating portion 20, the pusher 41 of the syringe 40 is located beyond the elastic hooking portion 24 of the accommodating portion 20, and the syringe 40 Is configured to overlap with the elastic hooking portion 24 in the vertical direction.

The bottom surface 35 of the section 30 is configured such that the position of the bottom surface 35B in the wide portion 30B is located below the bottom surface 35A in the narrow portion 30A by at least the size of the elastic hooking portion 24.

The accommodating portion 20 is made of a synthetic resin material or a metal material that is resistant to penetration of the injection needle of a syringe. The material of the accommodating portion 20 may be the same as or different from the material of the main body 11 and / or the lid 12.

On the lower surface of the accommodating portion 20 on the closed end side, a rotating shaft 23 rotatably fitted to a bearing 32 provided on the bottom surface 35A in the narrow portion 30A of the compartment 30 is provided. When the user lifts the open end side of the accommodating portion 20, the accommodating portion 20 rotates around the rotation shaft 23.

An inclined surface 22 is provided on the upper surface of the accommodating portion 20 on the closed end side, until the inclined surface 22 abuts on the inner wall 31 of the section 30 (narrow portion 30A) on the closed end side of the accommodating portion 20. , The user can rotate and lift the accommodating portion 20. As shown in FIG. 5, the angle θ between the longitudinal direction of the accommodating portion 20 and the horizontal plane (or the plane on which the syringe disposal box 10 is placed) is the arrangement relationship and inclination between the inner wall 31 and the accommodating portion 20. It can be adjusted by changing the angle of the surface 22. The angle θ at which the user feels that it is easy to insert the syringe into the accommodating portion 20 is not limited, but is 30 to 60 degrees, preferably 40 to 50 degrees, and most preferably 45 degrees.

When the open end side of the accommodating portion 20 is lifted until the inclined surface 22 abuts on the inner wall 31, the accommodating portion 20 is supported (simple lock) at the lifted position by the frictional force generated between the inclined surface 22 and the inner wall 31. Ru. With the simple lock, the user can hold the accommodating portion 20 in a lifted state without having to hold the accommodating portion 20 by hand. Further, since the simple lock is generated by the frictional force between the inclined surface 22 and the inner wall 31, the user can also release the simple lock with a relatively weak force. With a simple locking mechanism that utilizes the frictional force between the inclined surface 22 and the inner wall 31, when the used syringe is accommodated in the accommodating portion 20, the user holds the accommodating portion 20 with the hand that does not have the syringe. You don't have to hold it down. Therefore, when the accommodating portion 20 is pressed by hand, the occurrence of a needle stick accident in which an injection needle is accidentally stabbed in the hand is prevented or reduced.

Since it is sufficient that a sufficient frictional force is generated between the inner wall 31 of the compartment 30 and the inclined surface 22 on the closed end side of the accommodating portion 20 to support the open end side of the accommodating portion 20 at the raised position, it is inclined. The surface 22 may be flat or curved, or may be configured to have a plurality of fine irregularities so as to increase the frictional force.

An elastic hooking portion 24 is provided on the lower surface of the accommodating portion 20 on the opening end side in a convex shape so as not to interfere with the insertion of the syringe, and the elastic hooking portion 24 is provided with a protrusion 25. .. The protrusion 25 is engaged with the protrusion receiving portion 36 fixed to the bottom surface 35B of the wide portion 30B of the section 30, so that the accommodating portion 20 is hooked on the main body 11 and the accommodating portion 20 cannot rotate.

A part 34 of the bottom surface of the section 30 located between the elastic hooking portion 24 and the rotation shaft 23 in the front-rear direction of the syringe disposal box 10 is formed in a cantilever shape, and the cantilever-shaped bottom surface 34 is formed. It has a convex protrusion 33 on the top (on the lid 12 side). As shown in FIG. 4, when no external force is applied to the accommodating portion 20, the protrusion 33 pushes up the lower surface of the accommodating portion 20 upward, so that the accommodating portion 20 is not hooked on the main body 11. That is, the syringe disposal box 10 has a configuration in which the storage unit 20 is not hooked on the main body 11 unless the user pushes down the storage unit 20. With such a configuration, when accommodating a used syringe, the user is not required to perform an operation of releasing the hook of the accommodating portion 20 after opening the lid 12 of the syringe disposal box 10. Therefore, the user can easily lift the accommodating portion 20 at an angle at which the syringe can be easily inserted even if one hand is blocked or the fingertip is in a handicapped state.

FIG. 6 is a cross-sectional view taken along the line AA of the syringe disposal box 10 in which the storage unit 20 accommodating the syringe 40 is hooked on the main body 11 and the lid 12 is closed.

The user accommodates the syringe 40 in the accommodating portion 20, and pushes the opening end side of the accommodating portion 20 downward so that the protrusion 25 of the elastic hooking portion 24 becomes the bottom surface of the wide portion 35B of the section 30 of the main body 11. It engages with the protrusion receiving portion 36 fixed to the 35B, and the accommodating portion 20 is hooked to the main body 11. When the accommodating portion 20 is hooked on the main body 11, there is sufficient space between the pusher 41 of the syringe 40 and the inner wall 37 of the compartment 30 on the open end side of the accommodating portion 20 to take out the syringe 40. Since it does not exist, the syringe 40 is configured so as not to come out of the accommodating portion 20 unless the engagement between the accommodating portion 20 and the main body 11 is released.

The hooking of the accommodating portion 20 can be released by the user operating the elastic hooking portion 24 to remove the protrusion 25 from the protrusion receiving portion 36. However, when the accommodating portion 20 accommodating the syringe 40 is hooked on the main body 11, the elastic hooking portion 24 is located below the syringe 40 (between the syringe 40 and the bottom surface 35B of the compartment 30 in the height direction). Because of the configuration, it is difficult for the user to operate the elastic hook 24 on the back side of the syringe 40. That is, the syringe disposal box 10 is configured so that the user cannot easily remove the syringe 40 when the accommodating portion 20 accommodating the syringe 40 is hooked on the main body 11. With this configuration, it is difficult to take out the syringe 40 even if not only the syringe user but also another person (for example, an infant) touches the syringe disposal box 10 with interest, and it is possible to prevent the occurrence of needle stick accident. Can be reduced.

When disposing of the used syringe, the user can use the syringe disposal box according to the embodiment of the present invention.
(I) There is no need to put a cap on the needle of a used syringe,
(Ii) Even if one hand is blocked or the finger is inconvenient, the slide lock mechanism makes it easy to lock and unlock the lid of the syringe disposal box.
(Iii) Even if the lid of the syringe disposal box is opened, the accommodating portion is not locked to the main body, so that the operation of releasing the interlocking of the accommodating portion is not required, and the accommodating portion can be easily lifted.
(Iv) When the open end side of the containment part is lifted to the top, the accommodation part is simply locked and the accommodation part is supported at that position. There is no need to hold down the part,
(V) While the containment is locked to the body, there is no space between the syringe pusher and the inner wall of the compartment on the open end side of the containment to remove the syringe. Since the used syringe cannot be taken out and / or (vi) the elastic hooking part for releasing the hooking of the housing part is hidden under the used syringe, the hooking of the housing part is released. It becomes difficult to do.
In this way, the user can easily and safely store the used syringe in the syringe disposal box, and the used syringe after storage is safely fixed, so that the occurrence of needle stick accident is prevented or reduced. To.
