Description

Cylinder, needle and cap unified safety syringe.

The purpose of this invention

First, it is to provide a safety syringe structure that prevents stabbing so as not to get stuck by contaminated needle after using syringe.

Second, in the use of the safety syringe, the same operation as the operation of the existing syringe is reduced or reduced, so that users (doctors, nurses) who are professional workers have already learned and use the operation as they are accustomed to. To provide a convenient safety syringe to eliminate the hassle

Third, in order to overcome the reality that the use of safety syringes is desperately expensive, they can be manufactured at the same price as a general syringe or at a lower price than a general syringe, so that there are fewer parts, fewer raw materials, and a manufacturing process. It is to provide a safety syringe of this simple, simple structure.

Fourth, to prevent the reuse of the syringe, which is another cause of secondary infection, to provide a safety syringe that anyone can easily identify whether the syringe is used.

Fifth, the needle tip of the syringe before use of the safety syringe prevents exposure to external air, thereby providing a safety syringe structure that can prevent contamination before use.

The present invention relates to a safety syringe, and when looking at the prior art, there are general syringes used in the market and safety syringes that are being used in foreign countries.

The structure of a general syringe consists of a cylinder part for receiving and compressing a fluid as shown in FIG. 1, and a needle part for injecting a fluid extruded from the cylinder part, the main part of which includes a cylinder (1) for receiving a fluid, and the cylinder. (1) a piston (2), which is an actuator for introducing and discharging fluid while moving inside, a needle portion fixed to the cylinder (1), and a cap (3) for preventing and protecting the exposure of the needle portion do.

The cylinder 1 has a fluid receiving space 4 capable of accommodating a predetermined amount of fluid, and a cylinder head 5 having a flow path for entering and exiting the fluid at a tip end thereof.

The piston 2 is formed with a piston head 8 and a handle 6 for moving the piston head 8, which form a seal suitable for the inner diameter of the fluid receiving space 4 in the cylinder 1.

The syringe needle part is composed of a connecting part 7 which is fitted and fixed to the outer diameter of the cylinder head 5, and an injection needle 9 which is fixed to the connecting part 7 to inject fluid and protects or externally exposes the needle 9. Cap (3) for preventing is composed of one syringe set consisting of a removable structure on the outer diameter side of the connecting portion (7).

In the use situation of the syringe, first, while holding the drug to be dosed in the inner diameter fluid receiving space 4 of the cylinder 1, the knob 6 of the piston 2 is pressed and the piston head 8 moves to the cylinder ( 1) It moves while being sealed with the inner diameter, and the drug is administered to the subject through the needle (9).

Prior to this, the outside of the needle 9 is covered with a cap 3 to be protected, but the cap 3 is removed and used.

Cap (3) is attached to the coupling force of the degree that can be easily pulled out by pulling in the fixed state fixed by fitting to the outside of the connection portion 7 of the needle fixed to the cylinder head (5).

On the other hand, after the first use of the syringe is attached to the disassembled cap (3) for the hygienic treatment of the syringe to be collected separately.

In the general function of such a syringe, the tip of the needle (9) of the syringe is sharply processed so that if there is contact with the body, it can be deeply touched and easily infected, so that proper handling and management of the syringe is required. Despite much education and attention, secondary infections due to the stabbing of the syringe are frequently occurring. The United States official announcement (announced in 1999) announced that 1,000 healthcare workers were infected each year.

In order to reduce this phenomenon and to manage the needle more safely, it is preferable to cover the outside of the needle 9 with the cap 3 to eradicate the external exposure of the needle. As a result, there is a problem in that the cap 3 is reinserted after using the needle, and there is a problem of being stuck in the needle 9 even in the process of reinserting the cap 3, and there is a contradiction in which the cap 3 is frequently lost.

In addition, the risk of accidents of non-medical workers in general is very high, and the risk of cap 3 falling out during the disposal of the discarded syringe is also high.

Due to this relationship, several safety syringes have been devised and used to prevent puncture, but the structure is difficult to use due to its complex structure, and there are many additional devices, so the manufacturing cost is high, which is many times or tens of times the price of a conventional conventional syringe. It is not being distributed. The U.S. government has been encouraging the use of safety syringes since the end of 1999, and legislation is in force for the use of safety syringes, and other countries, including Korea, will follow the example of the United States.

The first technical problem of the present invention is to prevent the needle from being stuck in the syringe needle after the use of the syringe. Stuck in the process.

The present invention is designed so that the control cap 17, which performs the function of the cap (3) of the general syringe, is integrated with the syringe cylinder (1) and the needle (9) so that the lid does not need to be lost or replaced. After the user pushes the adjusting cap 17 in the tip direction by hand once, the locking cap guide and locking iron 18 of the adjusting cap 17 is locked to the needle connection fixing part 10 connected to the cylinder 1. By tightly fixed and fixed by the concave-convex (15) and concave-convex to prevent the source of the needle (9) exposed.

The second task is that since the main users of the syringe have already learned how to use the body as professional workers such as doctors and nurses, it should be similar to the existing syringe use operation and there should be no increase in use.

Looking at the operation of the existing syringe a) take out a new syringe from the packaging b) remove the cap (3). C) Poke the needle (9) into the injection bottle and draw the injection into the fluid receiving space (4) of the injection cylinder (1) d) Place the injection ㅁ) Put the cap (3) on the syringe again 시) Throw it in the trash. It can be roughly divided into six movements.

The present invention can not be passed by the natural slip on the connection fixing portion 10 of the cylinder (1) and the needle (9), but the physical force to stick the needle (9) to the rubber stopper of the injection bottle to extract the injection liquid Adjustable cap primary locking iron (13) can be turned into and with the natural sliding, but with a slight physical force, the adjusting cap guide and locking iron (18) of the adjusting cap (17) can be crossed Locking guide (12), and locking to guide the locking cap (15) of the locking cap (18) of the needle connection fixing portion (10) of the adjusting cap guide and locking iron (18) with a physical force to hold and push with fingers after use The crab has a fixed locking guided inclination (14) and a U-shaped groove, and there is a fixed locking yo (15) that is combined with the adjustment cap guide and locking iron (18), thereby providing an uneven locking device that can not be removed once bited. In addition, the tip of the control cap (17) is fitted with an adjustment cap wing (19) so that it is well gripped and slipped when pushed with a finger.

In this way, the operation of the safety syringe is to a) take a new syringe out of the packaging b) prick the needle into the injection bottle and pull out the injection solution. C) Place an injection. ㄹ) Push the adjustment cap to the irregularities. ㅁ) Thrown into the trash can and reduced to 5 movements.

As described above, the cap 3 is removed and replaced, and the control cap 17 is replaced with one push.

The third task is to identify the use and to prevent contamination before use.

Existing general syringes and other safety syringes can not know whether the use of the syringe, but in the present design when using the first time by sealing with a suture vinyl cover (20) on the front of the control cap wing (19) at the tip of the control cap (17) By allowing the needle 9 to penetrate the sealing vinyl cover 20, it is easy to identify whether the sealing vinyl cover 20 is perforated or not and to contact the syringe needle 9 with air or other substances before use. It is designed to prevent contamination due to

In addition, the pediatric syringe can put a pretty picture on the outer surface of the suture vinyl cover 20 to eliminate the fear of injection by showing only a pretty picture to the children without showing the end of the needle (9). When the injection solution is pulled out naturally, the control cap 17 is pushed back and caught in the control cap secondary locking iron 12 part (b) state. And the locking iron (18) is in the (A) position and the end of the needle (9) is hidden into the adjustment cap (17) so that the child sees only the picture printed on the outside of the suture vinyl cover (20). You just need to do it)

The needle connection fixing section 10 is made of a plastic cylinder, which is an extension of the injection cylinder (1) for fixing and fixing the cylinder (1) and the needle (9), and four wings of the same material to reinforce the cylinder are crosswise. There is a connecting fixing reinforcement wing 11 is formed.

In the cylindrical shape with the cross connection fixing reinforcement blades 11 of the needle connection fixing portion 10, the corresponding injection caps can be freely moved up and down, and the injection liquid is originally placed in the upper portion thereof. The adjustment pushed back to the lower part of the adjusting cap primary catching iron (13) and the space (B) which prevents the back of the adjusting cap (17) from receiving the physical force generated by sticking the needle (9) to the rubber stopper for drawing. Before the cap (17) to give a physical force is provided with a control cap secondary locking iron (12) to prevent the free movement forward, the upper locking locking guide slope 14 and the fixed locking yoke (15) Consists of the adjustment cap fixed concave-convex device consisting of and the departure prevention jaw 16.

The adjusting cap 17 is a cylinder of plastic material that is capable of acting as an injection needle 9 and the degree of exposure and sealing. The adjusting cap 17 is combined with the needle connecting fixing portion 10 and combined with the needle connecting fixing portion 10 to move up and down and to be fixed to the fixed concave-and-convex device. Kim Cheol (18) and the central circular and four-way cross-shaped needle connecting fixing hole (21) is formed. The inner diameter is drilled so that the injection needle (9) can pass through the top of the control cap (17) In order to easily adjust the adjusting cap 17, the outer side of the adjusting cap 17 has a plurality of contact protrusions 23, and an upper end of the adjusting cap wing 19 is provided so that the finger does not slip out of the adjusting cap 17. . Four clearance grooves 22 having different lengths connected to the needle connection fixing hole 21 are provided on the body of the adjustment cap 17 for smooth movement during the initial assembly and use of the adjustment cap 17.

Then, the sealing cap through-hole is sealed on the outer surface of the control cap wing 19 to attach a sealing vinyl cover 20 to enable identification of the driver's syringe and prevent contact with contaminated air.

The effect of the present invention is as follows.

The first effect is that there is no need to replace the cap (3) on the syringe needle (9) after use of the syringe, and loss of life resulting from secondary infection by preventing exposure of the tip of the syringe needle (9) with just one safe and simple action. According to the US government, 1,000 people per year, including medical workers and researchers, are stabbed with deadly hospital infections, such as AIDS and hepatitis. The loss of costs can be prevented.

The second effect is that anyone can easily identify the use of the syringe with the naked eye (distinguish between (a) and (c) state) to prevent infection due to the reuse of the syringe, and to clear the vague anxiety and distrust of the patient.

Thirdly, the safety syringe can be manufactured at the same price as a general syringe, and the rapid safety syringe price problem, which is the biggest obstacle to the dissemination of safety syringes, is solved. Mandatory use legislation and the price of safety syringes are about four times the price of regular syringes.
