Description

Anti-needle stick injury prevention device for needle pulling in infusion port

technical field

The utility model relates to the technical field of medical devices, in particular to an anti-needle puncture device for needle-pulling in an infusion port.

Background technique

The infusion port is a closed infusion device that is completely implanted in the human body, including the catheter part with the tip located in the superior vena cava and the injection seat implanted under the skin. Blood sample collection, etc. In the process of daily use of the infusion port, both hands are required for puncturing or needle withdrawal. One hand is used for operation, and the other hand is used for fixation. Generally, the thumb, index finger and middle finger are required to fix the infusion port in an arc shape. The operating hand is supported on the skin by the wrist to indicate puncture or needle extraction. During the operation, medical staff are often injured by needle sticks in the fixed hand due to unskilled or other factors. Nursing staff are prone to puncture due to the rebound of the back pressure of the needle when placing the butterfly needle or separating the infusion port from the butterfly wing needle at the end of the infusion. Injuries to non-operating hands, according to relevant literature reports, the probability of needle stick injury in the infusion port is 43.37%. Needle stick injury is the most direct and most critical way of occupational exposure for clinical nurses, and it is very common in clinical work. In order to reduce the risk of needle stick injuries in the infusion port for medical staff, a needle stick prevention device for needle extraction in the infusion port is required.

Utility model content

The purpose of the utility model is to provide an anti-needle puncture device for needle-pulling in an infusion port. When the utility model performs puncture, the fixed position of the body surface of the infusion port is found first, and then the skin is disinfected, gloves are worn, etc., and the skin and the silicone plug on the infusion port base are placed in the infusion port card slot after the preparation is completed. Stop and squeeze the block and press down the pressure plate and the base of the infusion port with a little force to fix it, and then the operator uses the butterfly needle to puncture the skin from the piercing groove. If the factor stabs the fixed hand, the stab-proof board can play a role in preventing the fixed hand from being stabbed.

When pulling out the butterfly needle: remove the wound dressing, complete the steps of disinfection, wearing gloves, etc., take the butterfly needle as the center, slide the pressure plate through the groove, insert the butterfly needle into the groove, and place the needle on the base of the infusion port. The silicone plug is placed in the slot of the infusion port; the pressure plate will be located between the skin and the butterfly needle; the fixed hand holds the grip handle downward with a little force to fix the pressure plate and the base of the infusion port without any displacement, and the operator pulls out the butterfly with a little force. pin. Since the fixed hand is located behind the stab-proof plate, if the operator holding the butterfly needle rebounds due to the back pressure when the needle is withdrawn, the stab-proof plate can play a role in preventing the fixed hand from being stabbed. The utility model has simple and convenient operation and strong practicability.

The utility model is realized in this way:

An anti-needle puncture device for needle-pulling in an infusion port, comprising a pressure plate, a vertical plate is integrally formed on the pressure plate, and a hand pinch block is integrally formed with the pressure plate on one side of the vertical plate, The pressing plate on the other side is provided with a through-groove penetrating the pressing plate, the top of the vertical plate and the vertical plate are inclined with a stab-proof plate, and the bottom end of the pressing plate is provided with a slot for infusion port. The pressing plate is made of hard plastic or rubber.

Further, an infusion port indwelling on the inner side of the human skin is matched with the infusion port card slot. The infusion port includes an infusion port base, and an infusion port silicone plug is arranged above the infusion port base.

Further, the piercing groove is used for piercing the dish-shaped needle.

Further, the inclination angle between the vertical plate and the stab-proof plate is 0°-120°.

Further, the stab-proof plate is made of soft rubber material, and a rubber gasket is embedded in the infusion port clamping groove. The soft rubber material can effectively resist the rebound of the needle, and the rubber gasket can prevent the hard contact between the pressure plate and the infusion port.

Compared with the prior art, the beneficial effects of the utility model are: the utility model is simple and convenient to operate and has strong practicability.
