Description

[Detailed description of the invention] [Industrial application field] This invention is intended for use with blood sampling needles, injection needles, etc. (hereinafter simply referred to as needles) that are used in hospitals, etc. to collect blood or give injections. device for safely removing a syringe (from a syringe).

[Conventional technology]

In recent years, vacuum suction blood collectors, syringes, etc. (hereinafter collectively referred to as blood collectors, etc. in this invention) have become disposable types, and are used blood collectors that have been used after drawing blood or injecting blood. These needles were removed from the blood collection tube (blood collection device body) and discarded to prevent the risk of becoming a vector for the transmission of viruses and other diseases.

Such needles are attached by screwing, taper fitting, or clipping to a synthetic resin ring tube.

When removing and discarding such a needle, for example, in the case of a screw-in needle, the conventional method is to manually cover the needle with a cap from the direction of the needle tip, twist the cap, remove the needle from the blood sampler body, and separate the cap and needle. He had thrown away the whole thing.

For example, FIG. 8 is an explanatory diagram of a conventional operation for removing the needle 102 of the suction blood sampler 100, in which the blood sampler with blood sampled is held in one hand 104 and the cap 106 is removed.
Hold it with another hand 108 (FIG. 8a) and insert it so as to cover the needle 102 from the tip side of the needle 102,
The internal gear-shaped protrusion carved in the cap 106 and the pinion-shaped protrusion at the base of the needle are engaged (eighth
Then, by twisting the cap 106, the needle 102 and the cap 106 were removed from the blood collection device body (FIG. 8c), and the needle and cap were disposed of in a deposit can or the like.

During this work, when the cap was placed on the needle, the needle could accidentally come into contact with the user's hand, resulting in an unexpected accident such as infection with hepatitis or the like due to the tip of the needle being inserted into the hand. Particularly in view of recent problems such as AIDS, there is a need for a device that can reliably and safely remove blood-stained needles.

[Problem that the invention attempts to solve]

The purpose of this invention is to eliminate all unexpected accidents caused by touching used needles.
An object of the present invention is to provide a removable storage container for used blood sampling needles, etc., which has a simple structure.

The present invention provides a safe, portable device that is convenient to use and includes a sealed container for storing the removed needle.

[Means for Solving the Problems] The present invention is a box body that has the function of safely and easily removing and storing used needles, and is equipped with the following characteristic technical means.

(1) It is a box with a lid that can be opened and closed. This lid is preferably hinged to the box body, for example, and biased in the opening direction when opened.

(2) Provide a notch in the rising part near the periphery where the lid contacts. This notch is large enough to engage the base of the needle with the needle tip facing into the box. Here, the rising part refers to the outer wall of the box or a plate-shaped member provided near the outer wall, and any shape may be used as long as it has a cutout and can be engaged with the needle.

(3) Furthermore, in a preferred embodiment, a pair of opposing shearing blades are attached to the back surface and part of the peripheral edge of the opening/closing lid.

[Effect]

The present invention has the following effects.

(a) Since it is a small and lightweight box, it is easy to carry and carry, and can be easily used anywhere.

(b) For screw-in needles, the needle can be easily removed by engaging the base of the needle in the notch on the periphery, pressing the lid against the base with one hand, and twisting the body of the blood sampler with the other hand. If the lid is allowed to move slightly in the opening direction, the needle will fall into the box and be stored.

(c) For tapered fitting type needles, when the base of the needle is engaged with the notch and twisted slightly in the lateral direction, the tapered part is easily removed and the needle is stored in the box.

(d) For Ringer's needles, etc., the ring fluid tube is sandwiched between the shearing blades provided between the lid and the box wall, and when the lid is closed, the needle is sheared and stored in the box.

(e) A removable inner bag made of synthetic resin film, etc. that fits inside the box is attached, and the needle can be safely and easily removed by storing the needle in this bag and discarding the bag. You can throw away the needles all at once.

(f) As mentioned above, this device is highly versatile as it can process various types of needles, etc. with just one device.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 and 2.

The device 1 of the embodiment consists of a box body 2 provided with a lid 3, which is hinged by a pin 4 so as to be openable and closable. When the lid 3 is released, it is biased in the opening direction by a spring 5, and when it is closed, it is kept closed by a latch 6. When the latch 6 is released by the button 7, the lid 3 is opened. is opened as shown in FIG.

The opening angle of this lid 3 may be 10 to 30 degrees. A partition wall 10 is provided as a rising portion near the peripheral edge where the back surface of the lid 3 comes into contact. The septum 10 has a plurality of notches 11 on its upper edge for removing the needle. Although this partition wall 10 is shown as a plate-shaped body provided inside a box, it is of course possible to use the outer wall of the box itself.

Any number of these notches may be provided to match the size of the base of the needle.

For example, FIG. 3 shows the process of removing a screw-in needle. As shown in Figure 3a, the needle 2 is inserted into the notch 11.
0 roots 21 are engaged.

FIG. 3b is the view taken along the line A-A. As shown in Figure 3c, press the lid 3 against the blood sampler body 2.
The needle 20 can be removed by twisting the needle 20, and by loosening the pressure on the lid 3 and allowing the lid 3 to separate as shown in FIG. 3d, the needle 20 will fall into the box and be stored.
A spring 12 is provided which lifts the rear part of the needle 20 and facilitates and secures the needle 20 into the box.

FIG. 4 is an explanatory view of the process of removing the needle 20 having a tapered fitting portion from the main body 24. Engage the fitting taper part of the root part of the needle 20 with the notch 11, and
b) and then, as shown in the plan view in FIG. 4c, by slightly twisting the main body 24 in the direction of the arrow 25, the needle 20 will very easily fall off and be stored in the box.

Figure 5 shows the tube 26 to which the needle 20 is attached.
This figure shows the process of cutting the needle 20 with a shear blade 30 and storing the needle 20 in the box. With the lid open, the tube 26 is positioned between the inner surface of the box and the shearing blade attached opposite to the lid 2, and when the lid 3 is closed, the tube is cut and the needle 20 is cut as shown in FIG. 5b.
is stored inside the box.

Figure 6 shows an example of a latch that keeps the lid 3 closed, and shows the hook 6 attached to the lid 3 and the box body 2.
When the lid 3 is closed, the hook 8 is engaged with the elastic hook 8 attached to the lid 3. When the button 7 is pressed, a mechanism for retracting the hook 8, such as a taper pin 9, acts to disengage the hook, and the lid 2 is opened. It opens due to the biasing force of the spring 5.

Inside the box body 2, an inner bag 40 made of synthetic resin film or the like as shown in FIG. Keep stored needles safe,
It can be easily disposed of in bulk.

[Effect of idea]

The removable container for used blood sampling needles, etc. of the present invention has the following excellent effects.

B. Any type of needle, such as a blood sampler or syringe, can be processed with one device.

(b) It is small and lightweight and can be easily transported along with a mobile medical equipment storage stand.

C. There is no risk of accidentally inserting a used needle into the skin.

(d) Handling of the needle after it has been removed is also safe and secure.
