Description

Auxiliary needle pulling and inserting device for transfusion port

Technical Field

The utility model relates to the field of medical equipment, especially, relate to an auxiliary needle pulling and inserting device for an infusion port.

Background

The port is an infusion device completely implanted in a human body, is mainly implanted by a right chest or an upper arm, has the advantages of long retention time, simple maintenance, capability of avoiding medicine extravasation and the like, and is widely applied to the treatment of infusing various medicines, venous high-energy nutrition, blood transfusion, blood sample collection and the like in clinic. Particularly in the field of tumor treatment, a safe and reliable venous access can be established through the infusion port for infusing chemotherapeutic drugs, but at present, the tumor incidence rate in China is high, and the characteristics of rising trend and low-age malignant tumor exist, so the infusion port is increasingly used in the treatment process of adult and child tumors.

The infusion port is implanted subcutaneously and comprises an infusion port seat, the infusion port seat can jack up the skin to form a circular bulge, and an external atraumatic needle (a butterfly wing needle) is required to be inserted to establish connection with the infusion port seat when medicine is infused. In clinical work, it is found that if a subcutaneous bag where an infusion port seat is located is loose and is lack of surrounding soft tissue fixation, the stability of the infusion port seat can be reduced, accurate positioning and needle insertion depth of medical workers during needle insertion are affected, the risk of needle insertion failure is likely to occur, pain caused by repeated puncture can be brought to a patient, and the service life of the infusion port can be affected due to complications such as displacement and turnover of the infusion port seat, local infection of a puncture point, and seepage of an infusion port caused by irregular operation in the process. In addition, in order to prevent leakage, the silicone septum on the infusion port seat is generally thick and the silicone material has high viscosity, so that the resistance generated when the needle is pulled out pulls the subcutaneous tissue of the patient, causing skin laxity and reducing the stability of the infusion port seat. Therefore, at present, clinical medical staff generally press the base of the transfusion port with two or three fingers when inserting and removing the atraumatic needle. However, when the transfusion port seat is pressed by a hand, the risk of pricking the fingers of medical staff exists during needle insertion, and when the needle is pulled out, the needle-holding hand can be rebounded unconsciously under the action of inertia, so that the medical staff is easily scratched, and the risk of infection of the medical staff by pathogens carried by the needle head is increased.

The utility model discloses a utility model with publication number CN207871222U discloses a device of preventing hindering of pulling out needle in infusion port, this prevent the ware of hindering when using, aim at the infusion port needle tubing with the semicircle orifice at upper plate and lower plate center, press the handle and make the bottom plate tightly push down the infusion port seat in infusion port, the puncture needle file is held between the fingers to the other hand, pull out the pjncture needle outward, can effectively avoid medical personnel's finger to contact the puncture needle tubing, the security that the needle was pulled out in infusion port has been improved, however, above-mentioned device of preventing hindering of pulling out needle in infusion port is the structure of similar clamp, it is inconvenient to be used for pressing, and push down the infusion port seat through the bottom plate, be difficult to accurately fix a position infusion port seat in subcutaneous position, press the local position or one side of infusion port seat easily, cause the application of force unbalanced, lead to pressing or even promote the infusion seat to take place skew or horizontal displacement easily. The utility model discloses a utility model patent of publication No. CN211068448U discloses a novel transfusion port needle extractor, this needle extractor passes through the chuck and cliies the both sides of transfusion port seat when using to restrict the displacement of transfusion port seat, however, the resistance that forms when pulling out the needle leads to mainly that the transfusion port seat takes place to pull in its axis direction, and above-mentioned chuck clamping force is in the both sides of transfusion port seat when the centre gripping, it needs to exert horizontal clamping force and vertical pressing force simultaneously when using, the strength of consuming is more and has the possibility that takes place relative movement between chuck and the transfusion port seat, and, can the area of centre gripping undersize when the bellied height of transfusion port seat is not high, exist the centre gripping inconvenient and easily cause the pressure damage to skin because of local pressure is too big.

How to solve the above problems is a technical problem to be solved urgently.
