Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a needle stick prevention device for a medical syringe.

[0002]

2. Description of the Related Art Conventionally, various measures have been taken in hospitals and the like to prevent nosocomial infection. In one example, the entire syringe is disposable. Alternatively, the injection needle attached to the tip of the syringe body is disposable. In addition, it is considered that it is desirable that the used needle is re-stored in the needle tube protection cap from the viewpoint of handling safety up to the subsequent disposal work. However, when storing the injection needle in the needle tube protection cap,
If there is a discrepancy, the finger holding the needle tube protection cap may be stabbed by the needle tip. In addition, when discarded into a waste container without being housed in the needle tube protection cap, an accident has occurred while transporting the exposed injection needle to the waste container. These needlestick injuries put healthcare workers at risk for infections such as AIDS and hepatitis.

[0003]

DISCLOSURE OF THE INVENTION The present invention avoids a dangerous operation such as storing a used needle of a syringe in a needle tube protection cap, and can safely dispose of the needle without leaking. Can be provided at a low cost with a simple structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a device for preventing a puncture accident of a syringe which covers the needle at the tip of the syringe. FIGS. 1 to 4 show an embodiment of an intravenous needle with a wing. As shown in FIGS. 1 and 2, the needle stick accident prevention device 1 is provided with bending lines 1 c and 1 d at substantially the center of a plate-like body.
1d, plate pieces 1a, 1
b is provided. A substantially U-shaped housing portion 2 for housing the winged intravenous needle 7 is provided at an intermediate portion of each of the plate pieces 1a and 1b. In addition, the needle stick accident prevention device 1 is formed of a synthetic resin material, a pulp material or the like, and the bending lines 1c and 1d are formed in a hinge shape to enable easy bending.

A locking portion 3 is formed on each of the plate pieces 1a and 1b on opposite surfaces which are bent and face each other.
1b are resiliently locked together when folded.

FIG. 3 shows a state in which the used winged intravenous needle 7 is stored in the needle stick accident prevention device 1 according to the first embodiment. By the way, the winged intravenous needle 6 has wing portions 7a and 7b on the left and right sides of the needle tube support portion 7, the needle tube 8 forward and the infusion tube 9 at the rear end.
Is provided.

First, the needle tube supporting portion 7 of the winged intravenous needle 6 from which the two wing portions 7a and 7b are picked up in a folded shape and extracted from the patient is inserted into the accommodating portion 2 of the needle stick accident prevention device 1. On the other hand, as shown in FIG. 4, it is placed together with the folded wings 7a and 7b.
FIG. 5 shows a partial cross-sectional view of the mounted state. Since the bottom 2a of the storage section 2 is inclined so as to be lower in the direction of the needle tip 8a of the winged intravenous needle 6 to be placed, the needle tip 8a comes into close contact with the needle stick accident prevention device 1. Subsequently, the plate pieces 1a and 1b are folded into the state shown in FIG. At this time, the needle tube 8 (hidden and invisible in the figure) of the winged intravenous needle 6 is covered with the recesses 4a and 4b (hidden and invisible in the figure) provided in the plate pieces 1a and 1b, and 9 is covered with the concave portions 5a and 5b. It is preferable that one of the recesses 4a and 4b is closed so that blood or the like attached to the needle tube 7 does not leak.

Next, FIGS. 7 and 8 are sectional views of the locking portion 3 before and after the plate pieces 1a and 1b are folded.
The locking portion 3 is provided with a hook portion 3a and a window portion 3b, and when the plate pieces 1a, 1b are folded, they are elastically locked to each other. There is no worry about being pulled out.

FIGS. 9 and 10 show an embodiment of a disposable injection needle. By the way, the disposable injection needle 10 has a needle tube 12 in front of a needle tube support portion 11 and a syringe body 1 at a rear end.
An opening end 11a connected to the third cylinder tip 13a and a flange portion 11b are provided.

First, the needle tube holding portion 11 of the disposable injection needle 10 which has been picked up from the patient by holding the syringe body 13 is inserted into the accommodating portion 2 of the needle stick accident prevention device 1 as shown in FIG. It is inserted and placed according to. An inclined surface 2b is provided on the open end surface at the rear end of the housing portion 2, and a portion sandwiched between the guide groove 2c and the inclined surface 2b is formed into a wedge 2d that expands in the insertion direction of the flange portion 11b. The wedge 2d is connected to the flange 1 of the disposable injection needle 10.
It serves to separate the space between the step 1b and the step 13b of the syringe body 13. The separated syringe body 13 can be separated and discarded as plastic waste.

[0016]

The needle temporarily holds the needle tube supporting portion of the injection needle in the storage portion, so that the needle does not roll down and falls, and the bottom of the storage portion is inclined so that the needle tip is in close contact with the plate piece. It is difficult to touch, so that the needle is covered with the needle.When attaching the needle to the needle tube protection cap as in the past, the hand gets out of order and the needle tip shifts from the opening of the needle tube protection cap, and the user picks up the needle tube protection cap. Accidents that hurt the fingertips are avoided. Further, when folded, the locking portion elastically locks the left and right plate pieces to each other, so that there is no fear that the injection needle is pulled out after being locked. This prevents infections such as AIDS and hepatitis without stabbing with a needle tip contaminated with blood or the like. In addition, the subsequent disposal is easy and safe.

[0017]

As described above, the structure and operation of the needle puncture accident preventive device of the present invention are as described above, and it is possible to prevent infection such as AIDS and hepatitis without piercing the needle tip contaminated with blood or the like. Further, since the structure is simple, it can be provided at an extremely low price.
