Abstract

The invention relates to a protective needle cover against syringe needle sticks consisting of a syringe (1), a needle (2), a protective needle cover (3), a clip (4), a slit (5) in the needle (2) cover instead of a vector approach in the circular structure of the needle (2) directly into the cover of the needle (2) after the needle (2) is used in the injection, which aims to place the needle (2) in the cover and prevents it from sticking into the hand, and protects the patient and healthcare professionals from the risk of infection as a result of sticking.

Description

A PROTECTIVE NEEDLE COVER AGAINST SYRINGE NEEDLE STICKS

Technical Field

The invention relates to the protective needle cover against syringe needle sticks, which prevents the sticking events in hand that occur during the closure of the cover of the syringe needle after injection in the healthcare sector and protects the patient and healthcare professionals from infection.

State of the Art

A syringe is a type of injector used in medical applications and is a piece of equipment designed to inject liquid drugs into the body. Basically, it consists of a needle and a syringe body containing the plunger. Syringes allow the drug to be administered to the body by a variety of injection methods (e.g., intramuscular, subcutaneous, or intravenous).

The needle is the basic element of the syringe. It is a thin and sterile needle used to inject liquid drugs into the patient's tissue. The needle allows the drug to be delivered to the muscle or tissue from the main application point of the syringe.

The syringe body is the part in which the needle and the drug are placed. This section, where the needle is attached, is made of a transparent material. Thus, users can see the level of the drug inside. The syringe body allows the drug to be injected into the body at the right dose.

A plunger is a mechanism used to push or withdraw the drug inside the syringe. It moves inside the syringe body and transfers the drug to the body through the needle. The correct operation of the plunger allows healthcare professionals to adjust the precise dosage of the drug.

The covers used in the syringes are designed to ensure that the needle remains sterile, and these covers ensure that the needle is stored hygienically before and after the syringe is used. It is removed before use and reinserted after injection. Present syringes are effective tools widely used in the application of medical treatments and vaccines and play an important role in the prevention and treatment of diseases. However, this method brings some negativities.

First, the use of syringe needles often causes pain and discomfort. Physical contact during the insertion of the needle into the skin creates an unpleasant feeling in many people. This is more evident, especially in individuals with a fear of needles and in children.

Second, since the syringe needles come into direct contact with the skin, they increase the risk of infection. Conditions such as non-sterility of the needle, failure to clean the injection site and sharing the syringes increase the risk of infection.

Third, when syringes are used, allergic reactions may develop against the drug and vaccine components they contain. In addition, some people experience undesirable side effects.

Fourth, syringes are difficult to use, especially in self-administration situations. Factors such as dosage settings and selection of the injection site cause user errors.

The accidental insertion of the needle into the hand during the closure of the cover of the syringe needle after the injection also causes negative effects. It increases the risk of penetration into the hand and injury to the user during closing the cover of the syringe needle. Contact with the piercing tip of the needle leads to skin injuries and skin infections.

In addition, the accidental insertion of the needle into the hand while the cover of the syringe needle is opened or closed jeopardizes the sterility of the needle. The transfer of bacteria and microbes from the hand where the needle comes into contact to the injection site increases the likelihood of infection. This situation causes complications and prolongation of the healing process during the treatment. The accidental insertion of the syringe needle into the hand causes occupational safety concerns among healthcare professionals. This situation increases the risk of causing accidents in the workplace, jeopardizing the safety and health of the healthcare professionals. In the event that there are diseases that can be transmitted by blood in the patient to whom the drug is administered, the same disease can be transmitted to the healthcare professional who punctures their hand with the needle. For these reasons, although a careful and attentive approach is taken to prevent sticking events during the process of closing the cover of the syringe needle after the injection, this situation cannot be prevented definitively.

Said invention eliminates the above-mentioned disadvantages based on the known situation. Only the needle cover has been changed without changing the syringe and needle used in the routine. The old type of needle cover that causes needle sticking embraces the needle starting from the needle tip and closed until the whole needle is covered, and there are cases where the needle cannot be inserted due to the narrowness of the cover axle that engages the needle tip. In the invention, instead of approaching from the same dangerous axle, it is used by opening and joining the cover by pulling it over the new axle opened on the side.

In this way, the risks of unwanted needle sticks and infection are eliminated.

The structural and characteristic features and all the advantages of the invention will be understood more clearly with the figures given below and the detailed description with reference to these figures, and therefore the evaluation should be made by taking these figures and detailed description into consideration.

Detailed Description of the Invention

The subject matter of the invention relates to the protective needle cover against syringe needle sticks, and it is explained only for a better understanding of the subject matter and in a way that does not have any limiting effect.

Said invention comprises the following:

• a syringe (1) in which the drug to be administered is placed and a needle (2) is attached to the tip,

• a needle (2) that allows the drug to be delivered to the appropriate site from the main point of administration of the syringe (1),

• a protective needle cover (3) that ensures the safety and sterility of the needle (2),

• a clip (4) that is not in the shape of a full circle and holds the needle (2),

• a slit (5) that allows the side insertion of the needle (2),

• a plunger (6) that pushes and withdraws the drug inside the syringe (1).

In the invention, the drug to be fed into the syringe (1) is withdrawn to the empty space in the syringe (1) with the plunger (6). After the needle (2) on the syringe (1) is positioned correctly, the drug is injected into the body by pushing the plunger (6) and the drug passes through the needle (1) to the body tissues.

After the injection process is completed, the needle (2) is removed, and the protective needle cover (3) is attached. The part of the needle (2) is placed in the slit (5) on the side of the protective needle cover (3) and is surrounded and fixed by the clips (4). The technical features mentioned in each claim are followed by a reference number, these reference numbers are used only to facilitate understanding of the claims, so that they should not be considered to limit the scope of any of the elements indicated by these reference numbers for illustrative purposes.

It is obvious that a person skilled in the art can make use of similar structures and/or apply this structure to other similar fields used in the relevant art. Therefore, it is obvious that such structures will lack the criterion of exceeding the innovation and especially the state of the art.
