Abstract
This is novel, and what relate to is that one prevents the bottle plug puncture unit that comes off, and comprises draw point and needle stand, is also connected with an anti-drop device bottom described needle stand; Described anti-drop device comprise symmetrically with needle stand bottom the connecting rod that links together and the slip-off preventing ring being arranged on connecting rod top symmetrically; Described slip-off preventing ring is semi-circular shape, and its longitudinal section is voussoir wide under upper point; Do not contact between described symmetrically arranged slip-off preventing ring is mutual, there is space centre; Described connecting rod has certain elasticity; Described needle stand and anti-drop device make by food grade plastic.
Description
Technical field
What this utility model related to is that one prevents the bottle plug puncture unit that comes off.
Background technology
In infusion process, if infusion strap is by external force tractive, easily comes off, cause syringe needle to pollute.Patient usually returns stamp from being about to syringe needle, causes liquid medicine contamination, even infusion reaction occurs.Therefore, need to design a kind of transfusion device preventing coming off.
Utility model content
In view of this, in order to solve the problem, basis is novel provides a kind of structure simple, effectively can prevent the bottle plug puncture unit come off.
One prevents the bottle plug puncture unit that comes off, and comprises draw point and needle stand, it is characterized in that also being connected with an anti-drop device bottom described needle stand; Described anti-drop device comprise symmetrically with needle stand bottom the connecting rod that links together and the slip-off preventing ring being arranged on connecting rod top symmetrically; Described slip-off preventing ring is semi-circular shape, and its longitudinal section is voussoir wide under upper point; Do not contact between described symmetrically arranged slip-off preventing ring is mutual, there is space centre; Described connecting rod has certain elasticity; Described needle stand and anti-drop device make by food grade plastic.
Further, described symmetrically arranged slip-off preventing ring can be reduced into lamellar from semi-circular shape, is still symmetrical arranged.
Beneficial effect:
1, described slip-off preventing ring is semi-circular shape, its longitudinal section is voussoir wide under upper point, after puncture of steel needles bottle stopper, voussoir tip can cross the neck part of infusion bottle easily, can be stuck in bottom voussoir in the projection of infusion bottle neck part, effectively coming off of causing by external force tractive of transfusion device anyway.
2, described slip-off preventing ring is semi-circular shape, and lifting surface area is large, can bear larger external force.
3, described connecting rod has certain elasticity, and when the neck part of infusion bottle is crossed in voussoir tip, connecting rod outwards opens; Cross the neck part of infusion bottle bottom voussoir after, connecting rod inwardly bounces back, and makes to be stuck in bottom voussoir in the projection of infusion bottle neck part.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Fig. 2 is slip-off preventing ring top view.
Fig. 3 is the A-A sectional view of slip-off preventing ring.
Detailed description of the invention
With reference to figure 1,2,3, one prevents the bottle plug puncture unit that comes off, and comprises the needle stand 3 of draw point 1 and food grade plastic making, is also connected with the anti-drop device 2 that a food grade plastic makes bottom described needle stand 3; Described anti-drop device 2 comprise symmetrically with needle stand 1 bottom link together, have certain elastic connecting rod 21 and be arranged on the semi-circular shape slip-off preventing ring 22 at connecting rod 21 top symmetrically; Described its longitudinal section of slip-off preventing ring 22 is voussoir wide under upper point; Do not contact between described symmetrically arranged slip-off preventing ring 22 is mutual, there is space centre.
Beneficial effect:
1, described slip-off preventing ring 22 is semi-circular shape, its longitudinal section is voussoir wide under upper point, after draw point 1 piercing vials, voussoir tip can cross the neck part of infusion bottle easily, can be stuck in bottom voussoir in the projection of infusion bottle neck part, effectively coming off of causing by external force tractive of transfusion device anyway.
2, described slip-off preventing ring 22 is semi-circular shape, and lifting surface area is large, can bear larger external force.
3, described connecting rod 21 has certain elasticity, and when the neck part of infusion bottle is crossed in voussoir tip, connecting rod 21 outwards opens; Cross the neck part of infusion bottle bottom voussoir after, connecting rod 21 inwardly bounces back, and makes to be stuck in bottom voussoir in the projection of infusion bottle neck part.
Claims (2)
1. prevent the bottle plug puncture unit that comes off, comprise draw point and needle stand, it is characterized in that bottom described needle stand, being also connected with an anti-drop device; Described anti-drop device comprise symmetrically with needle stand bottom the connecting rod that links together and the slip-off preventing ring being arranged on connecting rod top symmetrically; Described slip-off preventing ring is semi-circular shape, and its longitudinal section is voussoir wide under upper point; Do not contact between described symmetrically arranged slip-off preventing ring is mutual, there is space centre; Described connecting rod has certain elasticity; Described needle stand and anti-drop device make by food grade plastic.
