Description
Technical field
The utility model relates to the field of medical instrument technology more particularly to a kind of spikes of anti-dropout.
Background technique
It is typically necessary in clinical treatment and infusion treatment is carried out to patient (especially children), infusion apparatus passes through puncture outfit
Pierces through rubber stopper makes the medical fluid in infusion bag or infusion bottle be conveyed into patient's body by infusion apparatus.And existing infusion equipment exists
During patient's turn, walking or upper toilet etc., spike is easy to fall off from infusion bag or infusion bottle, and is infused
Puncture outfit because caused by the density of rubber stopper is different or nurse individual's dynamics operating reason tip spring back, puncture tip is exposed to air
In length be not easy, easily cause infusion infect probability, the increase of expense and the waste of medical fluid, also increase work to medical staff
It measures, there are insecurity factors, especially during fire rescues, need to rob the wounded in walking or road-work
Treatment is treated, it is easy to be caused bottle plug puncture unit to fall from infusion bottle, be given emergency treatment to a patient efficiency to not only influence medical staff, also
It will cause some latent dangerous factors.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of spike of anti-dropout.
The technical solution adopted in the utility model are as follows:
Baffle is arranged in a kind of spike of anti-dropout, including ontology, ontology centre, and the side below baffle is arranged empty
Air filter is arranged in gas channel, air duct end, and the top of baffle is puncture tip, is arranged between puncture tip and baffle
The anti-drop device of umbrella, the top surface of puncture tip are provided with inlet opening, and the side of puncture tip is provided with air inlet.
The anti-drop device of the umbrella includes the protrusion being fixed above ontology and is fixed at protrusion
The support claw of lower edge.
Protrusion, support claw and the ontology is integrated formed structure.
Baffle, venting channels and the ontology is also integrally formed.
The protrusion and support claw are made of plastics.
The protrusion annularly surrounds ontology one week, and raised end face is arc-shaped, and branch is vertically arranged below arcwall face
Support claw, support claw at least three are uniformly arranged a circle around protrusion, and support claw is elongated cylindrical or long laminated structure.
The diameter of the protrusion is less than the diameter of baffle, and the end of the support claw and the distance between baffle be not small
In the thickness of bottle stopper.
The other end of the air duct is connected with air inlet, and inlet opening is connected with input duct and input duct
Through entire ontology.
The utility model has the following beneficial effects: the anti-drop device of umbrella is provided on the spike of the application, when
After anti-drop device is inserted into infusion bottle, the support claw of anti-drop device can scatter certain angle outward under force
Degree, the top of bottle stopper is located in umbrella, in the case where there is external force to pull down spike, support claw can open completely, very
To protrusion is encased in the past, so that entire protrusion and support claw are not easy to go out from bottle stopper, have the function that anti-dropout.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram that the utility model is inserted into after infusion bottle.
Fig. 3 is the usage state diagram of the utility model.
In figure, 1, inlet opening, 2, protrusion, 3, baffle, 4, air duct, 5, air filter, 6, support claw, 7, air inlet
Hole, 8, ontology.
Specific embodiment
As shown in FIG. 1 to 3, baffle 3, gear are arranged among ontology 8 for a kind of spike of anti-dropout, including ontology 8
Air duct 4 is arranged in the side of 3 lower section of plate, and air filter 5 is arranged in 4 end of air duct, and the top of baffle 3 is puncture tip
The anti-drop device of umbrella is arranged in end between puncture tip and baffle 3, the top surface of puncture tip is provided with inlet opening 1, puncture tip
The side at end is provided with air inlet 7.
The anti-drop device of the umbrella includes being fixed at the protrusion 2 of 8 top of ontology and being fixed at convex
Play the support claw 6 of 2 lower edges.
Protrusion 2, support claw 6 and the ontology 8 is integrated formed structure.
The baffle 3, venting channels 4 are also integrally formed with ontology 8.
The protrusion 2 and support claw 6 is made of plastics.
The protrusion 2 annularly surrounds ontology 8 one weeks, and the end face of protrusion 2 is arc-shaped, is vertically arranged below arcwall face
Support claw 6, support claw 6 are at least three, are uniformly arranged a circle around protrusion 2, support claw 6 is elongated cylindrical or long sheet knot
Structure.
The diameter of the protrusion 2 is less than the diameter of baffle 3, the distance between the end of the support claw 6 and baffle 3
Not less than the thickness of bottle stopper 7.
The other end of the air duct 4 is connected with air inlet 7, and inlet opening 1 is connected with input duct and feed liquor
Pipeline runs through entire ontology 8.
When the utility model is used, the bottle stopper 7 for needing to pass through entire puncture outfit infusion bottle, enters in infusion bottle, In
During puncture outfit passes through bottle stopper 7, protrusion 2 will receive the power from bottle stopper 7 and be allowed to deform, to drive support claw 6
It deforms, is at this time the diameter of protrusion 2 across the width of bottle stopper 7, after entire puncture outfit passes through bottle stopper 7, all supports
The umbrella opened slightly outwards can be presented in pawl 6；Since support claw 6 is to open at this time, so that the diameter of protrusion 2 adds support claw
Across the width of bottle stopper 7 when 6 diameter is greater than to come in, so that puncture outfit be made to be not easy to fall off from bottle stopper 7, the work of anti-dropout is played
With.
Work as infusion-completed, when needing to take out puncture outfit from bottle stopper 7, use bigger power, by protrusion 2 and support claw 6
It is pulled out from bottle stopper 7, support claw 6 encases protrusion 2 at this time, needs to add two supports by the diameter that the width of bottle stopper 7 is protrusion 2
The thickness of the diameter of pawl 6.
