Description

Steel needle needle protector

technical field

The utility model belongs to the field of medical supplies, in particular to a needle protector for steel needles.

Background technique

When using a steel needle for venous infusion or venous blood drawing, the protective cap of the steel needle tip should be removed before puncturing and then discarded. Because the protective cap is very thin, the risk of injury to the sleeve is high, so the operation specification is not recommended. Set back after use. When the needle is pulled out after the infusion or blood is drawn, the needle is exposed, and the nurse needs to take the infusion device or blood collection needle to the disposal room or beside the infusion vehicle for sharps treatment. During this transport distance, the steel needle is always exposed, and the exposed needle can easily stab the nursing staff or the patients and other personnel in the ward. At the same time, discarding the exposed steel needle may easily puncture the sharps garbage disposal personnel.

In order to avoid needle exposure, some nursing staff use cotton swabs to protect the steel needles, but when the cotton swabs are too thin, the protection effect is not good. Some nurses also stick the steel needle back into the infusion set or used infusion bottle, but this operation nurses have a greater risk of needle stick injuries during the execution process.

Utility model content

The purpose of the utility model is to provide a needle tip protector for steel needles, which can effectively prevent the needle tip from being exposed and ensure the safety of operators.

In order to achieve the purpose, the utility model provides a steel needle needle protector, comprising a protective cylinder, an upper end opening arranged at one end of the protective cylinder for the needle of the steel needle to pass through, and an upper end opening arranged at the other end of the protective cylinder for connecting with the steel needle. The lower end opening through which the hose passes, the side wall of the protective cylinder is provided with a needle handle opening in parallel for the steel needle needle handle to extend out of the protection cylinder and for clamping the steel needle needle handle, the needle handle opening includes A first opening communicated with the upper end opening and a second opening communicated with the upper end opening for clamping the needle handle of the steel needle, the first opening and the second opening are on the same straight line and the width of the first opening is greater than that of the second opening opening, so that the needle handle of the steel needle goes out of the protective cylinder through the second opening, the first opening and the upper end opening in sequence, and an operating handle for safe operation is also provided on the side wall of the protective cylinder.

Preferably, the operating handle and the needle handle opening are opposite to each other on the protective barrel.

Preferably, each edge of the second opening is provided with a rubber layer for pressing the needle handle of the steel needle.

Compared with the prior art, the utility model has the following beneficial effects:

In the present invention, the needle handle opening for clamping the needle handle of the steel needle is arranged on the protective cylinder and the operating handle is arranged in coordination, so that the needle head can be effectively avoided from being exposed, and the safety of the operator can be ensured. In the present invention, by arranging the rubber layer on each side of the second opening, the friction force and the pressure on the needle handle of the steel needle can be effectively improved, so that the needle head can be prevented from being exposed and the safety of the operator can be ensured.

Detailed ways

The technical solutions of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

Example 1

As shown in Figures 1-2, a steel needle needle protector of the present invention comprises a protective cylinder 1, an upper end opening 11 provided at one end of the protective cylinder 1 for the steel needle needle to pass through, and an upper end opening 11 provided at the other end of the protective cylinder 1 for In the lower end opening 12 through which the hose connected with the steel needle passes, the side wall of the protective cylinder 1 is provided with a needle handle opening in parallel for the steel needle needle handle to extend out of the protective cylinder 1 and for clamping the steel needle needle handle. 2. The needle handle opening 2 includes a first opening 21 that communicates with the upper end opening 11 and a second opening 22 that communicates with the upper end opening 11 for clamping the steel needle handle. The first opening 21 and the second opening 22 are in the same On a straight line and the width of the first opening 21 is larger than that of the second opening 22, the needle handle of the steel needle passes through the second opening 22, the first opening 21 and the upper end opening 11 in turn and passes through the protective cylinder 1, and the side wall of the protective cylinder 1 is also provided with There is a handle 3 for safe operation use. The operating handle 3 and the needle handle opening 2 are located opposite to each other on the protection barrel 1 . Each side of the second opening 22 is provided with a rubber layer 5 for pressing the needle handle of the steel needle.

In this embodiment, the protective tube 1 and the operating handle 3 are integrally formed and are both made of hard plastic, so that the manufacture is simple and the material is safe. The connecting side of the first opening 21 and the second opening 22 is provided with a slope to make the connection smooth, and avoid jamming when the needle handle of the steel needle is inserted into the second opening 22 for clamping. The rubber layer 5 can effectively improve the friction force and the pressure on the needle handle of the steel needle, thereby improving the stability of the fixing of the steel needle. After the needle handle of the steel needle is clamped on the second opening 22, the needle tip of the steel needle is inside the protection tube 1 to avoid being exposed, and the distance between the needle tip of the steel needle and the upper opening 11 is not less than 2 mm. The inner diameter of the protective tube 1 is slightly larger than the outer diameter of the hose, so that the overall volume is small. When in use, grasp the operating handle 3 and the steel needle handle with both hands and apply force in reverse, so that the steel needle handle can pass through the second opening 22, the first opening 21 and the upper end opening 11 and pass through the protective cylinder 1 in sequence, so that the steel The entire needle can be used after being separated from the protective tube 1 . The protective cartridge 1 is now on the hose. After the steel needle is used, grasp the operating handle 3 and the steel needle handle with both hands and move in the opposite direction, so that the steel needle handle passes through the upper opening 11 and the first opening 21 and is stuck on the second opening 22 in sequence. The operation is simple and convenient, suitable for all patients who use steel needles for infusion, reducing the risk of needle stick injuries.

The above are only preferred embodiments of the present invention, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as the exclusion of other embodiments, but can be used in various other combinations, modifications and environments, and Modifications can be made within the scope contemplated herein by virtue of the above teachings or skill or knowledge in the relevant field. However, modifications and changes made by those skilled in the art do not depart from the spirit and scope of the present invention, and should all fall within the protection scope of the appended claims of the present invention.
