Abstract

The utility model discloses a disposable infusion needle head with a protective function, which comprises a needle head; a needle tube connecting end is fixed on the rear end of the needle head; a protective sleeve is arranged on the front end of the needle head; a clamp plate which is oblique to the needle tube connecting end is arranged on the needle head; an elastic device is arranged on the needle head; and the elastic device is fixedly connected with the protective sleeve through a connecting rope. When the infusion needle head is used, the protective sleeve is not thrown away as traditional infusion needle heads but being pulled backwards; at this time, the spring is compressed, the front end of the protective sleeve is jacked by the clamp plate, so that the needle head can be normally punctured into the blood vessels of a patient and play an infusion role; when the infusion needle head needs to be replaced due to the swelling of an infused part and other problems caused by various reasons, the needle head is pulled out from the body of the patient, the clamp plate is broken, an anti-slip sleeve leans forwards under the action of the force of the spring to protect the needle head and prevent the same from stabbing others.

Description

A kind of disposable infusion syringe needle that has safeguard function

Technical field:

This utility model relates to technical field of medical instruments, relates to a kind of disposable infusion syringe needle of the usefulness of infusing in particular.

Background technology:

After a lot of patients are sick, all can carry out infusion treatment in the hospital the inside, in transfusion, all be medicinal liquid to be imported in patient's the vein by infusion tube and infusion needle, play the effect of treatment.

In the time of transfusion; infusion tube plays the effect that connects infusion bottle; lower end at infusion tube is connected with infusion needle, and infusion needle generally comprises syringe needle, link and protective sleeve, and syringe needle inserts in patient's the vein; link is used for being connected with infusion tube; protective sleeve then is to be enclosed within on the syringe needle, plays the effect of protection, can either prevent that syringe needle is by pathogen contamination; also can prevent the needle sting people, but existing infusion needle also there is weak point:

1) existing infusion needle insertion patient's vein carries out in the infusion process, can make needle pierces blood vessel wall part swelling occur because of moving of patient sometimes, just need extract infusion needle this time, move to another place and thrust again, but extract at infusion needle, in the infusion needle process that the nurse goes to take new, old infusion needle hangs over the patient next door sometimes or is wrapped on the infusion tube, patient or others are stabbed in such placement easily, if patient body is healthy not bad, if transmissible disease is arranged, just might give other people with disease propagation, very dangerous;

2) existing infusion needle all needs the nurse to utilize shears that syringe needle is destroyed after use, prevents that syringe needle from being utilized once more.

The utility model content:

The purpose of this utility model provides a kind of disposable infusion syringe needle that has safeguard function, and it can be after syringe needle be extracted patient's blood vessel, protective jacket directly be enclosed within on the syringe needle and prevent needle sting others.

Technology solution of the present utility model is as follows:

A kind of disposable infusion syringe needle that has safeguard function comprises a syringe needle, and described syringe needle rear end is fixed with the needle tubing link, and the syringe needle front end is equipped with protective jacket; The clamp that oriented described needle tubing link tilts on the described syringe needle also has an elastic device on the described syringe needle, this elastic device is fixedlyed connected with described protective jacket by connecting rope.

Described a kind of disposable infusion syringe needle that has safeguard function, described elastic device is a cylindrically coiled spring, this spring is between described needle tubing link and clamp.

Described a kind of disposable infusion syringe needle that has safeguard function, described clamp become 15 degree-45 degree acute angles with described syringe needle.

Described a kind of disposable infusion syringe needle that has safeguard function has a seal cover on the described protective jacket.

Described a kind of disposable infusion syringe needle that has safeguard function, described connecting rope is a rubber band.

Described a kind of disposable infusion syringe needle that has safeguard function, described clamp and described syringe needle are one-body molded.

This utility model beneficial effect is:

1) this new structure is fairly simple, making is easy, low price, and is easy to use.

2) this novel infusion needle, when in use, protective jacket is not that picture infusion needle is in the past thrown away, but protective jacket is pulled back, this time, spring was compressed, the front end of protective jacket is withstood by clamp, the syringe needle of this moment equally can normally penetrate blood vessel with present, medicinal liquid is input in the patient's blood vessel, when needing to change infusion needle, extracts syringe needle and break disconnected clamp off with the fingers and thumb when going wrong, anti-sliding under the spring force effect of spring, lean out forward, syringe needle protection is lived, prevent that it from stabbing others.And broken off with the fingers and thumb and have no progeny when clamp, this syringe needle can not reuse, and has saved the step that nurse in the past need cut off syringe needle with shears.

Description of drawings:

Below in conjunction with accompanying drawing this utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is this novel user mode sketch map;

Fig. 3 is an A place enlarged diagram among Fig. 1.

The specific embodiment:

The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.

Embodiment sees accompanying drawing 1～3; A kind of disposable infusion syringe needle that has safeguard function comprises a syringe needle 1, and described syringe needle rear end is fixed with needle tubing link 2, and the syringe needle front end is equipped with protective jacket 3; The clamp 4 that oriented described needle tubing link tilts on the described syringe needle also has an elastic device 5 on the described syringe needle, this elastic device 5 is fixedlyed connected with described protective jacket by connecting rope 6.

Described elastic device 5 is a cylindrically coiled spring, and this spring is between described needle tubing link and clamp.

Described clamp becomes 15 degree-45 degree acute angles with described syringe needle.

The described anti-skidding seal cover 7 that put.

Described connecting rope is a rubber band.

Described clamp and described syringe needle are one-body molded.
