Description

Needle holder for implantable drug delivery devices

technical field

The utility model relates to the technical field of medical supplies, in particular to a special needle holder for an implantable drug delivery device.

Background technique

The implantable drug delivery device consists of an injection seat (including a self-sealing elastic part, a puncture limiter, and a locking clip) and a catheter. After the implantable drug delivery device is implanted under the skin of the human body, the injection seat needs to be punctured and injected to facilitate the The liquid medicine is infused into the human circulatory system or specific parts. In order to reduce the debris generated during the puncture process and prolong the service life of the instrument, it is necessary to use a special needle for puncture and infusion, that is, "special needle". The cooperation of the special needle and the implantable drug delivery device facilitates the injection operation, but there are also some problems when the special needle is used. The patient's blood may carry various dangerous pathogens, and the exposed needle tip after use may accidentally stab the medical staff, posing a threat to the safety of the medical staff. In addition, the extension tube and connection seat of the special needle are generally fixed on the patient by a transparent dressing or tape. When the patient moves too much, takes a bath, or sweats, it may cause the adhesive tape to become worse and cause the special needle to fall off. Under the long-term coverage of dressings or tapes, the skin is prone to puncture point bleeding, infection and allergies.

Chinese patent CN207203169U discloses an indwelling needle applicator, including an applicator body, a plastic film and an anti-adhesive isolation sheet, the applicator main body is located in the middle of the plastic film and the anti-adhesive isolation sheet, and the middle of the applicator body is transparent Soft glue, surrounded by paper material, one short side of the applicator body is provided with two opening lines perpendicular to the edge of the short side, and the two opening lines separate the applicator body into a piece of wings that can be torn apart independently The left edge of the wing patch is integrated with the application body, the indwelling needle pasted under the application body is U-shaped, and the positive pressure joint of the indwelling needle is pasted under the wing patch, The separately tearable wing patch is to separate the indwelling needle needle and the positive pressure joint into a U-shape, so that the two are not under the same bonding pressure, and tearing one of them will not interfere with the normal operation of the other. The applicator of the utility model can be used as a fixer for the special needle of the implantable drug delivery device, but the applicator of the utility model has poor waterproofness and air permeability, and it is easy to cause the indwelling needle to be applied when the patient sweats or takes a bath. The stickiness becomes poor or even falls off.
