FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely to devices for preventing a needle prick. The device for an injection needle resting on a needle-bearing element of a syringe is formed in the form of a single molded product, and it contains the first part made with the possibility of attachment to the specified needle-bearing element, and the second part providing a shield for the specified needle and made with the possibility of pivotally rotating relatively to the specified first part for opening the needle for use. The specified device is made with the possibility to take the first position in which the specified needle is protected for transporting the specified device before use, the second position in which the specified needle is opened for filling the syringe and performing an injection, the third position in which the specified needle is protected after filling the syringe, but before performing the injection, and the fourth position in which the needle is locked in the specified device after performing the injection. In one embodiment, the specified shield has a transport groove and a locking groove connected by means of a locking device, wherein this arrangement is such that in the specified third position, the needle is located inside the specified transport groove, and it has the possibility to move to the specified second position, and in the specified fourth position, the specified needle moves through the specified locking device into the specified locking groove, while the specified locking device prevents it from leaving the fourth position. The specified device also includes bulges for energy dispersion, which act to reduce the energy of the specified shield, when it returns to the third position and before the specified locking device comes into contact with the needle, in order to prevent any amount of liquid available on the needle from splashing out of the specified device.
