CN201959336U - Novel positive-pressure and anti-reflux safety remaining needle - Google Patents

Abstract

The utility model relates to a novel positive-pressure and anti-reflux safety remaining needle, which comprises a sheath, a remaining hose, a rivet, a steel needle, a needle bed, an anti-overflow plug, a casing pipe seat, a connecting pipe, a check clip, a positive-pressure device and an anti-reflux device (i.e. a positive-pressure and anti-reflux tee joint), wherein the positive-pressure and anti-reflux tee joint is used for directly replacing a tee joint on a common remaining needle. The novel positive-pressure and anti-reflux safety remaining needle has the advantages that the working capacity of medical workers is reduced, the haematogenous pollution is reduced and the risk of causing patients to death because of blood leakage is avoided.

Description

Malleation is prevented adverse current new type of safe remaining needle

Technical field

This utility model relates to the novel remaining needle of a kind of disposable safe remaining needle band positive-pressure function and anti-adverse current function.

Background technology

Common remaining needle is a kind of medical apparatus very commonly used in the medical treatment such as transfusion, blood transfusion or blood drawing, but used remaining needle exists some inconveniences and potential safety hazard in use; Now general hospital all is scalp acupuncture to be through on the calparine cap infuse when using remaining needle, when pulling out pin, also to wash remaining needle with heparin, and in the withdraw of the needle, also want withdraw of the needle limit, limit to push away liquid, in case being back to, hemostasis liquid stops up flexible pipe in the remaining needle; Y formula remaining needle is connected by joint with infusion set in use, but can have the unexpected disengaging situation of joint, can cause the sufferer life danger like this.

The utility model content

This utility model has solved the potential safety hazard that common remaining needle inconvenient operation and jointing come off at the safe type retention needle of the anti-adverse current of a kind of malleation of above not enough invention.

The technical scheme in the invention for solving the technical problem is:

The anti-adverse current new type of safe remaining needle of malleation comprises: sheath, indwelling flexible pipe, rivet, draw point, needle stand, anti-overflow plug, casing seat, connection tube and flow-stopping clip, positive pressure devices and anti-backflow device i.e. (malleation is prevented the adverse current threeway), and the anti-adverse current threeway of malleation directly replaces the threeway above the common remaining needle;

Advantage of the present utility model: positive-pressure function replaces calparine cap, avoids resulting in blockage, giving up and manage, reduce nursing work load because of tube sealing; Only need to handle with sterilized cotton ball the joint of the anti-adverse current threeway of malleation when infusing once more, the screwed union of just can screwing on then carries out transfusion operation; Anti-backflow device effectively prevents to produce the hemorrhage patient's of causing life danger because of the unexpected disengaging of infusion set joint in the infusion process.

The specific embodiment

As shown in Figure 1, malleation is prevented adverse current new type of safe remaining needle, comprises sheath (1), indwelling flexible pipe (2), rivet (3), draw point (4), draw point seat (5), anti-overflow plug (6), casing seat (7), connection tube (8) and flow-stopping clip (9), the anti-adverse current threeway (10) (being positive pressure devices and anti-backflow device) of malleation; Sheath (1) is enclosed within casing seat (7) one ends protections and keeps somewhere flexible pipe (2), and keep somewhere flexible pipe (2) and be contained on the rivet (3), casing seat (7) one ends pack into rivet (3) and indwelling flexible pipe (2), anti-overflow plug (6) is equipped with in inside; Draw point (4) the anti-overflow plug (6) that was connected with draw point seat (5) is inserted and is kept somewhere in the flexible pipe (2); Connection tube (8) one ends are connected with casing seat (7), and the other end is connected with the anti-adverse current threeway (10) of malleation, and flow-stopping clip (9) is enclosed within on the connection tube (8).

Fig. 2 is the enlarged drawing of the anti-adverse current threeway of malleation;

Fig. 3 is the profile of the anti-adverse current threeway of malleation, and 3-1 is a positive pressure connector, and 3-2 is anti-adverse current joint;

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.

Claims (2)

1. malleation is prevented adverse current new type of safe remaining needle, and it mainly comprises sheath, indwelling flexible pipe, rivet, draw point, draw point seat, anti-overflow plug, casing seat, connection tube and flow-stopping clip, the anti-adverse current threeway of malleation; Sheath is enclosed within casing seat one end protection and keeps somewhere flexible pipe, and keep somewhere flexible pipe and be contained on the rivet, pack into rivet and keep somewhere flexible pipe of casing seat one end, the anti-overflow plug is equipped with in inside; The draw point anti-overflow that was connected with the draw point seat plugs in the indwelling flexible pipe; Connection tube one end is connected with casing seat, and the other end is connected with the anti-adverse current threeway of malleation, and flow-stopping clip is enclosed within on the connection tube.

2. malleation according to claim 1 is prevented adverse current new type of safe remaining needle, it is characterized in that the anti-adverse current threeway of malleation of connection tube one end is positive pressure devices and anti-backflow device.
