Description

Paediatrics is with fixing protective equipment of remaining needle

Technical Field

The invention belongs to the technical field of pediatric medical instruments, and particularly relates to a pediatric indwelling needle fixing protective tool.

Background

When children are transfused, unlike adults, the forehead position is often selected instead of puncturing the region such as the arm and palm, because: 1. the discomfort is reduced, and people know that during transfusion, hands sometimes get cold, numb or even pain due to the reason that the temperature of liquid medicine is low during transfusion, and for children, the capillary vessels on the hands and feet are small, and the hands and feet can get cold frequently even when no transfusion is performed at ordinary times; 2. prevent the child from pulling and running the needle; 3. the puncture is easy, and the blood vessels on the hands and feet of the child are thin and are not easy to find.

Infusion often will be used and is kept somewhere the needle, especially treats children, because the use of keeping somewhere the needle can reduce the misery that the infant caused because of repeated venipuncture and the fear of making a needle feels, alleviates the irritated mood of the head of a family, the clinical medicine of being convenient for, the emergency treatment of urgent, critical patient is used medicine, alleviates nurse's work load, but now directly will keep somewhere the needle through the sticky tape and fix at the patient head, have some problems, for example: the adhesive tape with the fixing function is directly attached to the skin, so that the sweat and grease secreted by the skin are easy to reduce the attachment capacity of the adhesive tape after a long time; moreover, in order to prevent the remaining needle from falling off, the head of the remaining needle needs to be wrapped by a large area of adhesive tape, so that the adhesive tape is adhered with hair, and the pulling caused during replacement can cause pain to children; moreover, the long infusion tube is easy to be pulled by children, and for the convenience of operation, the infusion tube is communicated with the indwelling needle in a direct insertion mode, so that the risk of pulling and falling off can be caused by carelessness. Therefore, there is a need to provide a pediatric indwelling needle fixation protector to solve the above problems.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: the purpose provides a paediatrics is with keeping somewhere fixed protective equipment of needle to solve current head and keep somewhere that the fixed mode of needle drops easily, drag the hair and cause pain, and have the problem that the transfer line drops the risk, still can have better adaptability simultaneously.

In order to solve the technical problems, the invention adopts the following technical scheme:

a pediatric indwelling needle fixing protective tool comprises a head fixing plate and an elastic band; head fixed plate and elastic cord end to end fixed connection and enclose into cyclic annularly, the end of elastic cord and lean on the fixed regulation buckle that is provided with in outer one side, thereby the end of head fixed plate passes and adjusts the buckle and form closed formula loop configuration with the elastic cord the fixed chin fixed band that is provided with in interconnect department of head fixed plate and elastic cord, and chin fixed band perpendicular to head fixed plate or elastic cord, open the operation window portion that has the rectangle in the middle of the head fixed plate the needle device is kept somewhere to having placed in the regional scope of operation window portion.
