Abstract

PROBLEM TO BE SOLVED: To provide a stowing cap with handle for an injection needle to secure safety of a doctor or a nurse against danger of being infected from patient's blood by an accidental sticking of the injection needle into his/her finger on fitting a stowing cap to the injection needle immediately after giving an injection to a patient, and to enable to discriminate whether an injection needle has been used or not by the handle of the stowing cap to prevent a new patient's infection accident. SOLUTION: A handle 6 is equipped on a stowing cap 2 for an injection needle openably via a one-way hinge. The back side of the handle and the side face of the stowing cap are colored by a danger-showing color. When an injection needle is to be inserted and stowed into the stowing cap 3, the handle 6 is opened outward away from the stowing cap 2 so that gripping fingers are kept at a distance from the stowing cap. After completion of stowing, the danger-showing color on the back side of the handle 6 and the side face of the stowing cap 2 is revealed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[Industrial applications] Economical and simple safety equipment that can handle syringes used in the medical and medical fields more safely can prevent infection related to health and create a hygienic and safe medical environment. Provide to doctors, nurses, patients, medical researchers and medical waste collection and handling personnel.

[0001]

The present invention relates to a cap for protecting and storing an injection needle used in various types of sterilized single-use disposable syringes used in large quantities in the medical field. The risk of post-injection, which is often experienced by treating doctors and nurses when using a syringe with the needle stored in the needle, which may be infected with a pathogenic bacterium due to a needle stick accident at the fingertip Provides a means of safely reattaching the storage cap to the injection needle, eradicate needle stick accidents and ensure the safety of doctors and nurses, while simultaneously disposing of used syringes and needles to be discarded. In order to prevent accidental re-use by the patient, a display function for clearly identifying unused and used items is provided to provide a safe and sanitary medical environment for the patient, and Workers who collect and transport used syringes that have been discarded and used needles are also likely to have pathogens from patients, and must be handled with care. The fact that it is a dangerous needle with the possibility of infection due to the color and function that leaves used evidence on the storage cap and the handle connected to it,
It is intended to be able to be specified.

[0002]

2. Description of the Related Art Conventionally used sterile syringes and sterile injection needles attached to them, which are disposed of only once and used once, are now used by doctors and nurses to fill injection syringes with medicinal solutions. After that, temporarily reattach the storage cap for hygiene and protection of the needle tip, carry it to the vicinity of the patient, disinfect and wash the surface of the arm or part of the body, and then remove the storage cap from the syringe needle. Remove the needle gently and gently pierce the patient's body to inject the drug solution, then pull out the needle and put it in the dedicated syringe disposal container prepared nearby without attaching the cap, or place the storage cap for safety. And dispose of it as it is in a waste container, or separate the injection needle into an incineration container dedicated to infectious medical waste, and put the syringe body in a waste container dedicated to burning garbage and discard it separately. ing.

[0003] In detail, if a dedicated disposal container is near the hand without reattaching the storage cap after the injection to the patient, the syringe can be inserted as it is, and it is safe without causing a needle stick accident. Usually, when the patient is on the bed of a hospital room, unlike a doctor's office or an injection special treatment room, a doctor / nurse puts a syringe, cotton swab, and a hemostatic device on a tray and goes to the patient's room, and a syringe filled with a drug solution. Remove the storage cap from the injection needle, puncture the injection needle into the patient's body, gently inject the drug solution, pull out the needle, and for safety purposes, habitually reattach the storage cap, return it to the tray, and stop bleeding Although the procedure is performed and the procedure is completed, since the dedicated dumping container is not carried, the operation procedure of reattaching the storage cap is forced, and the used syringe is brought back to the room where the waste container is equipped, and then placed in the dedicated container. Abolished It is.

[0004] When the storage cap is reattached to the injection needle, the operation of reliably inserting a sharp and thin needle tip into the storage cap having an inner diameter of less than 6 mm is the eighth operation.
As shown in FIG. 8 and FIG. 8A, this is the most dangerous moment when a needlestick accident occurs. In particular, nurses are required to perform tens of injections to hundreds of injections a day, and to treat patients every day, so familiar operation procedures are naturally quick and customary and continuous. I can take measures. However, repetition of the same familiar operating procedure often slows attention and forgets that it is a dangerous operation, so a needlestick accident is more likely to occur to a skilled nurse who has been working for a long time than an inexperienced new nurse. Equal occurrences are caused by potential safety deficiencies in the operation of re-installing the storage cap, which remain unimproved.

The work of nurses in hospitals is extremely diverse and extremely busy, and the number of nurses is constantly short. The working environment is severe physical labor, including night shifts. Due to the small number of hospitals and the lack of nurses in most hospitals, nurses are often unable to resolve overwork with a small number of people and often work tired. Obviously, it is difficult for everyone to maintain power throughout the day, so for busy nurses a sterile, sanitary needle-worn syringe and contaminated injections already used by the patient before use. Nobody can distinguish it from a syringe with a needle because it has exactly the same appearance. It is the only memory of the nurse who used the syringe and does not hold information such as objective changes in appearance. If it is on a table or the like, there is a concern that it may be re-used for a new patient who misunderstands it as an unused product and causes serious infection accidents.

[0006] The Japanese prior art for the injection needle storage cap is as follows.
0, JP-A-64-76873, JP-A-64-10777
4 is a disk-shaped or funnel-shaped collar to protect the fingers
It is a form provided in the storage cap opening, and it is possible to prevent needle stick accidents safely as the area of the flange is made larger, but there is a limit to the diameter of the flange due to manufacturing restrictions,
In fact, even with a diameter of 50 millimeters, sterilizing the collared product and packing it in a film that maintains hygiene,
It is disadvantageous because it requires high cost economically, and when preparing injections for patients, during doctors and nurses during drug filling work,
Even in the work of transporting them by placing them on a tray near the front of the patient, the syringe rolls in an arc around the end of the collar on the table or tray and it is unstable, and it is necessary to prepare and handle many syringes. It is very difficult, and there is a risk of falling on the floor or falling out of the tray, resulting in extremely low workability for nurses.

[0007] In the case of a syringe with a collar, 10 to 20 syringes which could be prepared on a tray in the past were prepared.
Because it is impossible to line up closer than the radius of the tsuba,
The number of trays is reduced by half to four and five, and the tray is required to be twice or more, and the area of the table used for chemical liquid filling work must be doubled, which also poses a practical problem. It is a means that needs further improvement to gain the support of doctors and nurses.

[0008] Even before re-attachment after the injection, the flanged cap that is removed and placed in an arc shape draws extra attention of the person who handles it, thereby concentrating on the original injection work. Although it is effective only to prevent needle stick accidents by obstructing it, it is a means that leaves a challenge for improvement in operability and economics including preparation work in actual hospitals.

In the technology disclosed in the US patent, #
4650468, # 4747830, # 467500
5, etc., after the injection, the piston in the syringe is rotated once or half a turn to form a connection projection at the tip of the piston on the inside of the tip of the syringe. By inserting the piston and pulling the hub and injection needle into the cylinder after fitting to the helical hook, the injection needle that is at risk of infection is stored in the syringe to prevent needle stick accidents and reuse. It is an invention that made things possible. US Patents # 4579776, # 470
2738 and # 5055552 show a slide cover that holds a syringe body on which a syringe needle is mounted with a cylindrical outer shell having an inner diameter capable of being enclosed, and after injection, the slide cover is directed from above the syringe body to the needle tip. After moving the needle forward and completely concealing the tip of the injection needle inside the outer shell tube, the slide cover is formed so that it cannot be returned.It is fixed by a lock mechanism to prevent needle stick accidents and reuse. It is.

In the technology disclosed in US Pat. No. 4,804,371, the operation of re-attaching the cap after the injection by means of integrally attaching a storage cap to the outer periphery of the hub of the injection needle is performed with a fingertip before the dangerous needle tip. With the cap with needle hole attached to the coil spring, the injection needle is passed through the needle hole and compressed coaxially, the protruding trigger on the circumference of the hub The cap with a needle hole is held at the base of the hub until the injection is completed by the patient, so that the injection needle is exposed from the needle hole. By rotating the cap with a hole a half turn or a quarter and removing it from the trigger, the coil spring inside the cap is released from compression and instantly expands. End is stored needle tip into the cap beyond through is for safe disposal in that state.

Although the prior art disclosed in the United States has an excellent function of preventing needle sticks and preventing reuse, the operability is # 480373 for a person who handles it.
Except for 1, it is not simple and requires a complicated procedure that requires memorizing the correct usage. In addition, the invented syringe and injection needle are all precision and greatly different from the piston, cylinder and injection needle that constitute the conventional syringe,
Since it is composed of many complicated components and its production cost is several times higher than that of the conventional product, it is necessary to provide a consumable disposable syringe needle. From the viewpoint that it is important to have a product that can be handled by simple operation, which is the performance to be provided, and that it can be constructed into a practically inexpensive product, the number of complex main parts is large and the manufacturing required for their assembly is large. It is easy to push up costs,
Since it is a structural system that is difficult to simplify such as reducing the number of components, there is still room for improvement.

[0012]

As shown in FIG. 8, the greatest cause of the accident is as follows.
The essential operation is to bring the thumb and forefinger closer to the nearest few millimeters of the sharp needle tip to which the patient's blood adheres when placing the storage cap held by holding the other hand with the other hand. Failure to insert the needle into the opening less than this will cause the needle tip to fall out of the storage cap and easily stick into the thumb or forefinger, as shown in FIG. 8A. It is an issue.

[0013] The disaster caused by this simple mistake, despite the fact that infecting doctors and nurses with infectious diseases, such as AIDS and hepatitis, due to viral infection, requires enormous difficult treatment and compensation. At present, the safety of doctors and nurses has not yet been established because systems and tools for preventing needlesticks have not been adopted at injection sites including bedside.

[0014] The main reason is that even if the system has an excellent effect, doctors and nurses who handle it are preventive products that require troublesome operations, and the price of disposable products is significantly higher than conventional products. If it is expensive, it will be rejected due to hospital business profits and will not be recruited, and as a result, the risk of needle stick accidents will continue to be left unimproved, even though the accidents are victims It is rarely even recognized that the person handling and handling the workplace safety and hygiene that is considered to be at their own risk as a carelessness of the person handling it is liable for the obligation to make improvements. The current situation is that, first of all, the priority condition is that the product price and business profitability are subject to adoption judgment.From the current situation, the important point required for a safe storage cap is that the operation is simple and inexpensive with a simple configuration. price It is an important point that it is a practical product that can be manufactured with, along with the function that can eradicate needle stick accidents, it has excellent functions and operability that satisfies those requirements and obtains the support of doctors and nurses who use it. It is an object of the present invention to provide a storage cap for a syringe needle.

[0015]

A storage cap (2) having a shape similar to that of a conventionally used injection needle storage cap is attached to a main body with an elongated handle for gripping, and the storage cap (2) is remounted. In some cases, the finger is moved to the side of the needle from the front of the tip of the injection needle by the length of the handle so that the storage cap can be easily covered with the injection needle. Needle storage cap (2) formed in a container with one end open and the other end closed
A hinge (13) for attaching a handle (6) having a rotation axis different from the vertical axis by 90 degrees on the outer wall surface near the opening, and being disposed inside the hinge; Has a one-way trigger (4) formed on a wedge-shaped protruding tooth.

At the same time, the storage cap (2) is attached to one end (11) of a handle (6) formed of a thermoplastic resin and having a length not exceeding twice the total length of the main body, in a shaft hole of a hinge. Is formed in a one-way gear (12) having a rotation axis that differs by 90 degrees from the axis of the handle (2) in the vertical direction, and meshes with the one-way trigger (4) in the hinge (13). Due to the configuration in which the handle (6) is attached so that it can be deployed only in one direction, the deployment angle of the handle (6) connected to the injection needle storage cap can be up to 170 degrees outward with the position near the storage cap side wall being 0 degree. At the same time, the space between the teeth is divided and formed with a plurality of teeth. Specifically, the positions of the teeth divided and arranged on the circumference around the axis of the one-way gear are set to 0 degrees and 45 degrees.
The one-way trigger (4) is engaged at each tooth valley formed at five locations of degrees, 90 degrees, 120 degrees, and 170 degrees, and the position is held, and furthermore, only one direction is developed outward and returned to the rear. It is a structure that cannot do it.

Furthermore, the back side (1) of the handle (6)
8) That is, the side near the injection needle storage cap (2) and the outer wall portion (17) of the storage cap covered by the attached handle (2) are painted or colored with a color different from the material color of the storage cap body and the handle. More specifically, any one of red, orange, yellow, and the like effective for danger display is adopted for the above-mentioned painted or colored portion, and the angle of the deployed position of the handle (2) is at least 45 degrees or more and 170 degrees or less. When extended to the extent, the colored part (17) of the outer wall of the storage cap, which was concealed by the handle (6), and the danger-indicating color on the back of the handle (18), are clearly used after injection. Re-attaching the storage cap (2) to the used injection needle is a configuration that enables identification from the deployed and fixed position of the handle (2) and exposure of the danger display color.

[0018]

The operation exerted by the expandable connection of the handle (6) to the one-way hinge (13) of the storage cap (2) is performed as an operation performed during the necessary injection treatment of the doctor and nurse. A prescription drug solution of a patient is suction-filled from a vial or an ampoule into a syringe barrel (5) equipped with an unused sterilized injection needle, and then carried to the patient's waiting side for disinfecting the arm or body surface. During preparation for wiping, it is necessary to temporarily re-attach the storage cap for the purpose of hygiene and protection so that the needle of the syringe itself does not damage the needle tip in the exposed state, At this time, the handle (6) was extended 45 degrees outward from the side wall of the storage cap (2) and gripped, and the needle tip (9) was inserted into the storage cap opening (10) to make a loose fit. Carry the patient to the side in front of the patient And it is injected into the body surface after performing disinfection wipe.

The injection needle inserted into the patient's body for treatment or examination touches the patient's flesh and body fluid after pulling out the injection needle attached to the tip of the injection cylinder after injecting a drug solution or collecting blood. In order to safely dispose the needle tip so as not to damage the body surface of another person, the storage cap is reattached to the injection needle. In the operating procedure, the handle (2) of the storage cap (2) has already been deployed at least 45 degrees outward from the storage cap main body side. The finger can be held at a position 90 degrees laterally from the position immediately before the thin and sharp needle point (9) by the length of the handle (6).

By this operation, the storage cap opening (10) can be safely and easily approached toward the needle tip (9), and the needle tip (9) is securely inserted into the opening, and the hub ( Pull in the storage cap (2) to the base of 7), and it is loosely fitted and attached, and the hub (7) of the injection needle
To further insert the storage cap (2) tightly so that it does not come loose, pull the handle (6) along the syringe barrel and connect it to the one-way hinge (13) of the storage cap (2). The engagement of the one-way gear (12) of the handle (6) and the one-way trigger (4) in the hinge, together with its tooth profile characteristics, enhances the flexibility and elasticity of the thermoplastic resin, which constitutes both of them. One-way trigger (4) formed on wedge-shaped protruding teeth using
However, the one-way gear (12) is allowed to rotate only to the outside due to the shape and elasticity of the protruding teeth which return immediately after the tip is bent and bent by an external force from the vicinity of the center and is released from the external force. And the deployment position of the handle (6)
From the angle of 0 degrees to a maximum of 170 degrees, a partial force of the mechanical vector of the pulling force of the gripping and operating person becomes a rotational force about the hinge axis, and the handle (6) is unfolded. By rotating the position closer to the syringe barrel (5) side, the storage cap (2) can be fitted tightly.

In the manufacturing process of the injection needle product, when the injection needle is attached to the storage cap (2), if the handle (6) is expanded at least 30 degrees or more, preferably 45 degrees, there is no conventional handle. The storage cap mounting machine can be used as it is.

Furthermore, when the products in the subsequent process are successively packaged in a film, the handle position can be set to a closed state at a deployment angle of 0 ° near the side wall of the storage cap, so that the packaging form is different from the conventional product. In addition, the handle (6) is compact without any obstruction, the conventional film wrapping machine can be used as it is, and it can be manufactured without requiring any special new equipment. In addition, the product packaging volume is the same as the conventional one, and has a feature that is excellent in economical efficiency, such as being several times lower than the cost of packing and transporting the flanged cap product.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a front view of an injection needle storage unit (1) in a state where a sterilized injection needle (8) is stored in the storage cap (2) with a handle for an injection needle, and an opening of the storage cap body. The handle (6) is attached to a hinge (13) standing upright in the vicinity, and shows an initial state in a closed position in contact with a side wall of the storage cap (2).

The length of the handle in the embodiment is a length obtained by adding 25 mm to the entire length of the main body of the storage cap (2), and the handle (6) is held with one hand at the time of reattachment. In order to facilitate opening outward from the position near the side wall of the storage cap, the storage cap is formed to have a length in which two fingers can be hung forward from the end of the storage cap.

FIG. 2 is a side view of the injection needle storage unit (1) of FIG. 1, wherein a handle (6) is formed near a side wall of an opening of the storage cap, and a rim (3) of a hinge (13).
2 shows a state where the storage cap main body (2) is held at an angle of 0 degree which is a closed state.

When the handle (6) has a plate shape, a thickness of about 2 millimeters and a width of 5 millimeters or 6 millimeters, a flexible handle can be formed in combination with the length of the handle. The surface near one end is provided with irregularities for the purpose of increasing friction, to prevent slipping when picking and pulling, at least for the entire length of the handle.
The handle is prevented from slipping out between the pinched fingers by forming the handle in one-half area, the storage cap is pulled strongly through the handle (6), and the base of the hub (7) of the injection needle (8) is pulled. Useful for tight fitting.

FIG. 2A is a sectional view taken along the line 1a-1a in FIG.
FIG. 3 is an enlarged cross-sectional view showing the engagement state of the one-way hinge (13) of the storage cap and the one-way gear (12) formed at the end of the handle, and the one-way trigger (4) formed on the wedge-shaped projection tooth is The handle (6) is in a state in which it bites into the valley of the one-way gear first tooth and holds the angle of 0 degree when the deployed position is closed.

FIG. 3 is a side view showing a state in which the injection needle storage unit (1) is mounted on the hub (14) of the injection cylinder (5).
Storage cap (2) until vial is ready
With the syringe needle attached, the needle is protected from contamination. After opening the prescribed ampoule or vial, the storage cap (2) is removed from the syringe needle (8) of the syringe, and the syringe needle is exposed to expose the syringe needle. The needle tip (9) is inserted into the medicinal solution inside or in the vial, and the piston (16) of the syringe (5) is inserted.
The filling is carried out by suctioning by pulling out.

FIG. 4 is a side view showing the operation sequence of the handle (6) deployed position when the storage cap (2) is remounted after the injection into the patient is completed. The state of the imaginary position indicated by the dashed line where the handle (6) is closed and held tightly on the side wall of the storage cap (2) body is the injection needle storage unit (1) attached to the injection cylinder (5) to inject the patient. ), Remove the storage cap (2) and insert the injection needle (8)
At the handle position when exposed, after the injection is completed in this state, at least the handle (6) is unfolded as shown in the figure in order to reattach the storage cap (2) to the needle tip (9). The angle is opened to 90 degrees or more, and the handle end is pinched and held, and the sharp needle tip (9) to which the body fluid of the patient is attached and the center axis of the storage cap opening (10) are mutually aligned. The needle (8) can be introduced into the opening (10) of the storage cap (2) very safely when approaching and facing.

FIG. 4A is a view taken in the direction of arrow 2b-2 in FIG.
b is a front view of the opening (10) of the storage cap (2) by the handle b, showing a state where the handle (6) is connected to the rim (3) of the hinge (13) formed near the opening; The diameter of the opening (10) of the storage cap (10) is formed with a slope having a smaller inner diameter toward the cylinder bottom, so that the fitting is firmly held when the hub (7) of the injection needle is stored.

FIG. 5 is a side view showing a post-process in the time series of FIG. 4, in which a sharp needle tip (9) is introduced into the opening (10) of the storage cap (2), and further injection is performed. 7 shows the process of insertion towards the end of the hub (7) of the needle. The deployed position of the handle (6) remains in the position of FIG. 4, with the opening (10) of the storage cap (2) being the hub (7) of the injection needle.
Until the base of the syringe is reached, both the injection needle of the syringe barrel (5) and the storage cap (2) can be inserted and fitted together.

Since the fitting at that time is loose, if the handle (6) is continuously pulled along the syringe barrel for the purpose of further tightening, the handle (2) flexes around the hinge axis while bending. The one-way gear (12) of the handle, which is rotated in the pulling direction and penetrates the axis of the one-way hinge (13), deflects the bite of the wedge-shaped projection tooth, which is the one-way trigger (4). The rotation angle of the one-way gear (12) is advanced to the angle where the one-way gear (12) is displaced and balanced with the traction force. Are held in mesh with each other, and the direction of the traction force is adjusted by the injection needle (8) of the syringe barrel.
The tight storage cap can be fitted and mounted by the force of the mechanical vector so as to approach the shaft center.

FIG. 5A is an enlarged cross-sectional view taken along a cutting line 3c-3c in FIG. 5, and the engagement position between the one-way gear (12) of the handle (6) and the one-way trigger (4) of the storage cap is as follows. This is a deployed position of the handle when the needle tip is retracted while being held in a state in which it is bitten and held in the second tooth valley. The deployment position in actual use is preferably 90
Degree is desirable, but more than that is dangerous needle point (9)
There is no particular limitation on moving the finger which is pinched from the side in the horizontal direction by the length of the handle (6).

FIG. 6 is a side view, which is a post-process of the time series shown in FIG. 5 and shows a process of putting the storage cap (2) deeply by the injection needle (8) of the injection cylinder (5). When the opening (10) of the needle is in a position to reach a loose fit with the hub (7) of the injection needle, the insertion of both the storage cap (2) and the needle (8) increases the frictional force of the mutual fit. Therefore, when reaching the equilibrium point where the approach stops, the handle (6)
The handle (6) flexes and is connected to the hinge by the continuous traction force of the fingers held and gripped.
Of the one-way gear (12), which is the base of the one-way hinge (13), and the handle is deployed closer to the side of the syringe barrel, and starts to rotate about the axis of the one-way hinge (13). Of a wedge-shaped protruding tooth made of resin,
The position at which the one-way trigger (4) and the one-way gear (12) have been engaged so far is held by the rotational force of the handle (2) from the vicinity of the center of the protruding teeth of the one-way trigger (4) to the tip. One Way Gear (1
The tooth is pushed away by the tooth of 2), bent and disengaged, and moves to the third tooth valley, which is the next biting position, and the one-way trigger (4) is resiliently held by the original wedge-shaped. The bending is restored to the shape, and the shape is held.

FIG. 6A shows the cutting line 4d shown in FIG.
FIG. 4d is an enlarged cross-sectional view of the one-way hinge (13) according to -4d. When the one-way gear (12) and the one-way trigger (4) in the hinge (13) at the handle deployment position are engaged, the one-way trigger (4) of the wedge-shaped protruding tooth engages and holds the third tooth valley. It is in the state of doing.

FIG. 7 further shows that the retracting cap (2) is tightly attached to the hub (7) of the injection needle, and is continuously pulled by the hand holding the handle (2) so as to fit the fitting.
The handle (6) bends again, and the one-way gear (1) of the one-way hinge (13) connected to the base of the handle (6).
As a result, the one-way gear (12) is rotated past the one-way trigger, and the fourth holding gear is pushed away.
Proceed to the third meshing position, one way trigger (4)
Is engaged and held in the fourth tooth valley of the one-way gear (12).

The handle (6) comes closest to the vicinity of the syringe barrel, and the pulling force acts so as to be parallel to the axis of the injection needle (8).
The storage cap (2) can be fitted tightly to the hub (7) of the injection needle by effectively increasing the traction force while rotating about the axis of the needle. FIG. 7A is an enlarged cross-sectional view of the one-way hinge (13) taken along the line 5e-5e in FIG.
One way trigger (4) is one way gear (12)
4 shows a state in which the handle (6) is in the final deployed position by being engaged with and held in the fourth tooth valley.

FIG. (8) is a perspective view showing a state of reattachment to the injection needle using the conventional injection needle storage cap (15), and the fingers for holding and holding the storage cap are inevitable. Then, it is exposed to a few millimeters in front of the sharp needle point,
Moreover, in order to insert a fine needle tip into the opening of the storage cap that is less than 6 mm in diameter, the injection needle and the storage cap that touched the patient's blood and meat are cross-inserted into each other to form a tight fit. Here are the operating procedures that are still ongoing.

FIG. 8A is a time-series perspective view of FIG. 8, showing a typical accident in which the needle tip comes out of the opening of the storage cap and sticks into the index finger, and the storage cap is re-mounted after injection. It can be understood that some of the essential operating procedures have unavoidable and highly dangerous causes.

FIG. 9 is a perspective view. When using the storage cap with handle (2) to store the injection needle immediately after injection, simply deploy and hold the handle (6) to easily and easily store it with improved safe operating procedures. It is shown. The fingers to be pinched by the simple method of the present invention are moved away from the dangerous needle point (9) by the length of the handle (6) and completely positioned in the 90-degree direction on the axis of the injection needle. The operation procedure can be changed to eradicate a needlestick accident.

FIG. 10 is a time series perspective view of FIG. In order to insert the injection needle further deeply into the storage cap (2) to ensure a tight fit, the tip of the opening of the storage cap with handle (2) that has reached the hub (7) of the injection needle is: When the handle (6) connected to the one-way hinge (13) is further pulled, the handle (6) further moves up to 170 along the syringe barrel by the action of the hinge.
To the extent that the retractable cap (2) is more easily retracted, thereby increasing the mechanical component of the traction force for a tight fit, and the thicker position of the needle hub (7). Then, the tip of the opening (10) of the storage cap (2) can be pulled in and fitted tightly.

At the same time, the engagement of the one-way trigger (4) in the hinge is advanced to the tooth valley formed at the maximum deployment angle of 170 degrees of the one-way gear (12), and the one-way gear (12) is engaged with the handle (6). ) Cannot be returned to the original deployed position direction. Therefore, even if the injection needle is stored carelessly after the needle is stored, the position of the handle (6) is set to the first position. As shown in FIG. 2 and FIG. 3, since the needle is clearly different from a sterilized, sanitary needle in a preparatory stage before use, even a person other than the handling person himself / herself can use the neglected needle. From the deployed position of the storage cap handle (6), it is easy to identify that the used injection needle is stored, so that it is promptly discarded as a contaminant that should be dumped in a dedicated medical waste disposal container. I can do it. The manner and position of the handle are established not only at the hinge position adopted by the storage cap (2) but also at other positions on the storage cap main body, and the effects of the invention can be considered in other forms than shown.

FIG. 11 is a side view of the storage cap with handle (2), showing a state in which the handle (6) is expanded to the maximum. The colored portion for the danger display is an unused injection needle which is colored only on the back surface (18) of the handle (6) and the outer wall portion (17) of the storage cap closed and covered by the handle. It provides a means of identifying whether the needle is a used injection needle that has a possibility of infection after use. Back side of handle (6) (1
The handle (6) is stored by adopting one of red, orange, and yellow, which is a color indicating danger, on the side wall portion (17) of the storage cap and being colored narrower than the width of the handle (6). From the vicinity of the cap body (2) to the outside, at least 4
When deployed more than 5 degrees, the color of the color is exposed, so that the storage of the injection needle is completed.
Because the position is unfolded at least 120 degrees or more and up to 170 degrees, for example, colored as a dangerous color, for example, red is from the side wall portion (17) of the storage cap to the tip of the back surface (18) of the handle (6). The red color is continuously exposed in a straight line, and it is dangerous for anyone who handles the syringe, not only the person who handled the syringe, to use a syringe with a used needle that should be discarded. Can be reliably determined. Further, although not shown, even if the colored area of the danger display color of the storage cap with the handle is limited to only the back surface (18) of the handle (6), the storage cap with the handle for the injection needle has The action and effect can be exhibited without change.

[0044]

[Effect 1] By attaching the handle (6) to the one-way hinge (13) formed on the side wall of the injection needle storage cap (2), it is possible to protect the needle tip after filling the syringe with the drug solution. The operation of reattaching the cap for ensuring hygiene and the operation of reattaching the storage cap (2) to the injection needle immediately after the injection simply deploys the handle (2) closed on the side wall of the storage cap to the outside. The position of the finger holding and gripping the handle (6) only by the simple operation of the above is moved away from the point of the sharp injection needle by at least 45 degrees to 90 degrees laterally, by the distance of the length of the handle. The first object of the present invention is to prevent a needle stick accident regardless of the experience of doctors and nurses, regardless of the level of experience of the injection procedure. No danger or worry, pole Since the storing operation of the injection needle can be performed safely and safely, the effect completely achieves the object of the invention as clearly shown in FIG. 9 and FIG. In addition, it is possible to provide a safe storage cap with a handle for an injection needle, which completely removes a dangerous re-attachment operation that had to expose a finger.

[Effect 2] The back surface of the handle (6)
The storage cap (2) is covered with a handle (6) on the side wall,
When the storage cap (2) is re-attached to the injection needle (8) of the syringe barrel by adopting any one of red, orange or yellow colored for danger indication on the wall surface, the handle is used. After the operation of unfolding and inserting the injection needle and fitting the storage cap tightly is completed, the position of the handle (6) is at least 120 degrees or more, at most 17 degrees.
By expanding the storage cap (2) outward from the main body to 0 degrees, the one-way gear (12) and the one-way trigger (4) are engaged, so that the position can be maintained without returning to the original position. Since it is possible to fix the injection needle, the second purpose of the invention is to complete the provision of the discriminating function between before and after use of the injection needle, and as a result, the injection needle stored in the storage cap is mounted. The injection device is provided to the person other than the person who has handled the syringe, whether the handle (6) of the storage cap (2) storing the injection needle (8) is clearly used or not, and the surface of the handle. And the dangerous color that is colored on the wall surface of the storage cap (2) can be easily identified by visual inspection whether it is exposed or not.
Even if the nurse is busy or tired and has reduced attention, it is a syringe that should not be overlooked as a used needle and must be alerted and discarded. It is effective to immediately discard it into a dedicated waste container, and can prevent misuse due to misplacement due to inadvertent mistake, for example, an unused syringe with a syringe equipped with the used injection needle However, even if there is a danger that it will be mistakenly left in places where many are placed side by side, the handle (6) can be distinguished from unused sanitary needles, which was impossible with the conventional needle cap. In addition to what can be done by different positions, the storage cap when storing an unused injection needle has the handle deployment position at 0 degrees or 45 degrees, and the danger display color on the storage cap wall is Although it is exposed in the case of 5 degrees, the colored portion on the back surface of the handle (6) is at an angle that is hard to see, and when the handle is completely tightened, the storage cap (2) and the injection needle (8) are attached. When the handle is tightly fitted, the deployment position of the handle at this time is a position deployed from 120 degrees to 170 degrees, and one of the danger display colors, red, orange, and yellow, is aligned with the back surface (18) of the handle. A portion (17) colored to the width of the handle is exposed on the side wall of the storage cap, so that a danger color in a straight line between the hinge from the tip of the storage cap to the tip of the handle is kept clearly visible. Therefore, any person who performs injection can immediately determine that it is a used contaminated injection needle to be discarded, and in addition to the effect of preventing a serious accident such as accidentally being used again by a patient. , Those doctors Dangerous color indicated on the syringe needle storage cap (2) that it is a dangerous medical waste that has the possibility of infecting many people involved in collecting, transporting and incinerating waste. Can be clearly identified from the data, so that there is a danger of infection due to a needle stick accident before being incinerated.

[Effect 3] A one-way gear (12) is formed at one end of a handle (6) formed of a thermoplastic resin, and is connected to a one-way hinge (13) on a storage cap body. ) Is an extremely simple function that only expands around the hinge, and the parts required for manufacturing are also included in the storage cap (2) body and handle (6).
The conventional cap-making device, needle-loading device and needle-needle-continuous-film-wrapping machine for manufacturing and assembling them only in pieces can be manufactured with very slight modifications, and the handle (6) Only the equipment for assembling the handle with the mold for forming the storage cap and the storage cap is a new facility, and as a result, it is possible to commercialize the storage cap with the handle for the injection needle. The cost is low, because mass production can be easily produced on the conventional production line as well as the conventional cap,
The third object of the present invention is to solve the many practical drawbacks of the prior art storage cap, realize a low product price, achieve high safety, and achieve simple operation. A storage cap with a handle for an injection needle for preventing a needle stick accident having excellent characteristics can be provided in the medical and medical fields.
