Description

A retention needle fixation device for nursing

technical field

The invention relates to the field of retention needles, in particular to a retention needle fixing device for nursing.

Background technique

The retained needle is a needle that penetrates into the blood vessel for a long time and can be reused many times. It can relieve the pain of multiple injections, especially for patients with edema, children and elderly patients. At present, domestic retained needles are mainly fixed by medical tape, but since the medical tape is pasted on the surface of human skin, long-term retention will cause skin irritation, especially for patients with sensitive skin, which will cause skin damage. Moreover, as the weather changes, sweat will be produced on the surface of the skin, thereby reducing the stickiness of the medical tape, causing the tape to detach from the skin surface, causing "needle running"; , will also cause "running the needle", which will cause more damage.

Therefore, many devices that can fix retained needles have been developed. Our team has long been engaged in the fixation of retained needles for nursing care and self-developed related equipment, and some products are widely used in hospitals, and after a lot of our efforts Retrieval and reference found that the existing retained needles mainly have publication numbers such as JP2003517894A, JP2002085558A, EP1985323A1 and N201510573354.X. These fixing devices often use adhesives or straps to strengthen the fixing effect of retained needles. The overall protection is not enough, or some will choose to add a shield to achieve closed and isolated protection for the area where the retained needle is placed, but these institutions also require the nurse to insert the retained needle into the human body before achieving isolation. When the operator inserts the needle Sometimes there are no more hands to pick up the fixed equipment, which requires the cooperation of multiple people to complete, so such equipment requires more manpower to cooperate, or some equipment can first insert the retained needle, and then insert the infusion The catheter is placed back on the fixed device with a tube slot, and the operation will be more complicated. Moreover, these devices are also equipped with a heating plate at the position of the infusion tube. The changing temperature may affect the width of the infusion tube and the liquid medicine in the infusion tube. thereby negatively impacting treatment.
