Description

A kind of Anti-stabbing infusion apparatus

Technical field

The utility model relates to medical instruments fields, and in particular to a kind of Anti-stabbing infusion apparatus.

Background technique

Venous transfusion is using atmospheric pressure and fluid pressure principle that a large amount of sterile liquids, electrolyte, drug is defeated by vein Enter intracorporal method.Disposable transfusion device is that the medical treatment consumptive materials that one kind is common in venous transfusion establish vein by aseptic process The channel between medical fluid.Generally it is made of the connection of the part such as syringe needle, needle cap, hose, filter, governor, dropper, puncture outfit. It can be punctured after needing first to remove needle cap when use, since needle cap is individual component, generally directly be abandoned.When patient is defeated After liquid finishes, to avoid needlestick injuries people, usually there is the following two kinds processing method:

1, it inserts the needle into after dropper and integrally loses into Biohazard Waste bucket, since dropper material is thicker, in insertion process In be easy to stab the hand of nursing staff, and cleanup crew is when clearing up Biohazard Waste bucket, is easy syringe needle from dropper again It extracts, the dead space capacity leakage that may cause in infusion apparatus causes chemical contamination, and exposed syringe needle can bring needle to cleanup crew The risk stabbed is unfavorable for hospital infection control management；

2, syringe needle is put into individual sharp instrument box after infusion apparatus separation, and sharp instrument box higher cost, and separation process was both Increase workload increases needle again and stabs probability.

Utility model content

The utility model aim is: bringing needle to pierce since needle cap is abandoned after use for existing disposable transfusion device Catch cold danger and the high problem of sharp instrument box use cost, a kind of Anti-stabbing infusion apparatus be provided, the infusion apparatus by needle cap and infusion apparatus into Row connection, easily covers needle cap on syringe needle after infusion-completed, can not only reduce needle and stab risk, but also can avoid Using individual sharp instrument box to achieve the purpose that save the cost, it is also beneficial to hospital infection control management.

To achieve the goals above, the technical solution adopted in the utility model are as follows:

A kind of Anti-stabbing infusion apparatus, including puncture outfit, dropper, governor, filter and the needle being sequentially connected in series by hose Head is cased with needle cap on the syringe needle, connecting component is equipped between needle cap and infusion apparatus, the connecting component can be according to needle cap Situation of movement and elongate or shorten automatically.

The utility model is lost after can removing to avoid needle cap by the way that connecting component is arranged between needle cap and infusion apparatus Abandon lose, needle cap is covered on syringe needle after infusion-completed, without insert the needle into again dropper or by syringe needle from Be put into individual sharp instrument box after infusion apparatus separation, can not only reduce needle and stab risk, but can avoid using individual sharp instrument box with Achieve the purpose that save the cost, and due to the connecting component can according to needle cap situation of movement automatic telescopic, conveniently remove needle cap, Simultaneously can be too long to avoid connecting component and influence the use of infusion apparatus.

As a preferred embodiment of the present invention, the connecting component includes the lantern ring covered on the hose of infusion apparatus tail portion, The lantern ring is equipped with the elastic string being connected with needle cap.By the way that lantern ring is arranged on the hose of infusion apparatus tail portion, and set on lantern ring The case where setting the elastic string being connected with needle cap, can needle cap being connected with infusion apparatus in this way, needle cap is avoided to go out active, and adopt Needle cap is not only conveniently removed with elastic string, but also avoids elastic string too long and influences the use of infusion apparatus.

As a preferred embodiment of the present invention, the lantern ring is made of elastic material.By the way that lantern ring is used elasticity Material is made, and can be integrally formed with elastic string, while again by the set ring set in infusion apparatus after being made in order to infusion apparatus On.

As a preferred embodiment of the present invention, its internal diameter is adapted the lantern ring with hose outside diameter in its natural state. Using such design can in order to by needle cap together with lantern ring along hose slide, avoid to acupuncture treatment operation affect, while Before lantern ring can be blocked in the needle wing on syringe needle, prevent lantern ring from slipping from syringe needle.

As a preferred embodiment of the present invention, needle cap head tube wall is equipped with grooving, the notch width and needle Needle wing thickness on head is adapted, and rubber stopper is equipped in needle cap tail portion, and after the needle wing is pushed into grooving, syringe needle can penetrate rubber In plug.It, both can be with by that syringe needle can be pierced into the rubber stopper in needle cap after grooving and push-in that the needle wing is aligned in needle cap The dead space capacity leakage in hose is prevented, and needle cap can be further avoided and slipped from syringe needle.

As a preferred embodiment of the present invention, the infusion apparatus further includes check valve, and the check valve is set to filter On hose between syringe needle.By the way that check valve is arranged on infusion apparatus, blood back situation can occur to avoid after infusion.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1, the utility model occurs after can removing to avoid needle cap by the way that connecting component is arranged between needle cap and infusion apparatus It abandons and loses, cover needle cap on syringe needle after infusion-completed, without inserting the needle into dropper again or by syringe needle It is put into individual sharp instrument box after infusion apparatus separation, can not only reduce needle and stab risk, but also can avoid using individual sharp instrument box To achieve the purpose that save the cost, and due to the connecting component can according to needle cap situation of movement automatic telescopic, conveniently remove needle Cap, at the same can be too long to avoid connecting component and influence the use of infusion apparatus；

2, the utility model is by being arranged lantern ring on the hose of infusion apparatus tail portion, and setting is connected with needle cap on lantern ring Elastic string the case where being connected with infusion apparatus by needle cap in this way, needle cap is avoided to go out active, and was both facilitated using elastic string Needle cap is removed, and avoids elastic string too long and influences the use of infusion apparatus；

3, syringe needle by that can be pierced into after the grooving in needle wing alignment needle cap and push-in in needle cap by the utility model In rubber stopper, the dead space capacity in hose can not only be prevented to leak, but also needle cap can be further avoided and slipped from syringe needle.
