Description

Indwelling needle fixator

Technical Field

The utility model relates to a fixator, in particular to an indwelling needle fixator, belonging to the technical field of medical treatment.

Background technique

An intravenous catheter is also known as an intravenous cannula needle. Its core components include a soft cannula that can be placed in the blood vessel and a stainless steel puncture guide needle core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, leaving only the soft catheter in the blood vessel for infusion therapy. At the same time, part of the extension tube and the connector are fixed on the arm, and only the connector needs to be docked during infusion.

However, the traditional way to fix the indwelling needle is usually to stick it with medical tape. However, when fixing the indwelling needle on a child's arm, the tail of the indwelling needle can easily be touched and pulled by the child, causing the needle tip to slip out and cause injury to the child's hand. It can also cause the indwelling needle to lose its function, causing inconvenience for subsequent infusion treatment.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3, an indwelling needle holder includes a cover plate 1, the cover plate 1 is provided with a fixing mechanism 3, the fixing mechanism 3 includes a connecting rod 301, the connecting rod 301 is fixedly connected to both sides of the cover plate 1, two connecting rods 301 are rotatably connected with fixing straps 302, the right fixing strap 302 is fixedly connected with a Velcro female surface 303, and the left fixing strap 302 is fixedly connected with a Velcro male surface 304, and a limiting mechanism 2 is provided at the bottom of the cover plate 1.

As a technical optimization solution of the utility model, the fixing mechanism 3 also includes a slot 305. The bottom end of the cover plate 1 is provided with a slot 305 with an arc-shaped cross-section. The setting of the slot 305 can prevent the cover plate 1 from slipping back and forth, thereby ensuring the stability of the device when in use.

As a technical optimization solution of the utility model, the Velcro female surface 303 and the Velcro male surface 304 are bonded and used in combination, and the Velcro female surface 303 and the Velcro male surface 304 are the same in size and shape.

As a technical optimization solution of the utility model, the limiting mechanism 2 includes a rubber pad 201, and two limiting blocks 202 with trapezoidal cross-sections are fixedly connected to the rubber pad 201; the setting of the rubber pad 201 can avoid the long-term contact between the tail of the indwelling needle and the skin and cause skin pain, and the trapezoidal structure design of the limiting block 202 can make the cover plate 1 and the rubber pad 201 fit more closely.

As a technical optimization solution of the utility model, a groove 203 is formed between the two limit blocks 202, and the groove 203 is connected to the card slot 305; the coordinated use of the groove 203 and the card slot 305 makes the cooperation between the devices more coordinated, while reducing the occurrence of slippage, and is more stable when used.

As a technical optimization solution of the utility model, the cover plate 1 is provided with an identification mechanism 4, and the identification mechanism 4 includes a fixed frame 401. The cover plate 1 is fixedly connected with the fixing frame 401, and the fixing frame 401 is fixedly connected with a transparent plate 402; the cross-section of the fixing frame 401 is a U-shaped structure, and the transparent plate 402 is provided with a notch 403. The setting of the fixing frame 401 can move the personal information card originally worn on the bracelet to the fixing frame 401, thereby reducing the items worn on the hand and reducing the burden on the hand.
