Abstract

The utility model discloses a kind of transfusion device bottle cork needle, it is characterized in that: the total length arranging transfusion device bottle cork needle is 28mm, on puncture needle, fluid passage entrance is 12mm apart from Aculeata, and fluid passage entrance is 16mm apart from needle tip.This utility model, by improving the structure of transfusion device bottle cork needle, reduces medicinal liquid remaining, eliminates safe hidden trouble.

Description

A kind of transfusion device bottle cork needle

Technical field

This utility model relates to a kind of transfusion device bottle cork needle.

Background technology

Venous transfusion is route of administration important clinically.According to the national standard of GB8368-2005 about disposable infusion set, the total length of transfusion device bottle cork needle is 28mm, on puncture needle, fluid passage entrance is 18mm apart from Aculeata, fluid passage entrance is 10mm apart from needle tip, the bottle stopper thickness of current various infusion bottle is 0.5cm to the maximum, therefore, for such situation, in infusion process, " rationally losing " phenomenon of the certain medicinal liquid of transfusion bottle stopper puncture outfit long-term existence.This " rationally losing " causes the medicinal liquid entered in body can not reach required concentration on the one hand, affects the treatment of disease; The waste problem causing valuable medicinal liquid very important on the other hand, brings loss to patient.For albumin, albumin is the costly medicine commonly used clinically, for the minimizing of prevention and therapy circulating blood volume, rescue shock, treatment hypoproteinemia etc., 25ml mono-bottle of price 220 yuan, the remaining medicine adopting transfusion bottle stopper puncture outfit of the prior art to cause albumin in bottle reaches 5.5ml.Particularly important for the medication of neonate department infant in addition, the dosage of neonate own is just few, and waste medicinal liquid possibly cannot reach optimum medicine concentration and effect.In order to avoid this situation, be, when infusion bottle herb liquid will be use up, transfusion bottle stopper puncture needle will artificially be descended pull-out one section clinically, medicinal liquid is dripped off as far as possible, ensure curative effect of medication, reduce drug waste.But, unavoidably have bottle cork needle exposed parts in downdraw process to cause polluting with direct contact of air with nurse's hands, when follow-up replacing infusion bottle, expose in atmosphere or the bottle cork needle being subject to the contact of nurse's hands very likely cause the particle contamination of follow-up medicinal liquid, these contaminate particulates enter human body by transfusion and cause local circulation obstacle, blood vessel embolism, make histanoxia and produce the serious problems such as edema and phlebitis.Dip thing microorganism culturing by the cotton swab of the transfusion device puncture needle exposed 150 examples to find: in 150 examples, have 8 routine cotton swab microorganism culturings positive, wherein gram positive bacteria 5 example, gram-negative bacteria 1 example, Grain-positive bacillus 1 example, fungus 1 example, microorganism positive rate is 5.3%.2 examples the 2nd bottle of liquid gravy is cultivated positive, and be gram positive coccus, microorganism positive rate is 1.3%.

This be, bottle cork needle front end of the prior art syringe needle is cone, found by clinical trial, cone puncture needle puncture time due to syringe needle sharp not, point of puncture and fluid passage entrance very near, easily make crumb of bottle stopper enter in infusion bottle, cause infusion reaction, blocking transfusion device cause liquid not drip, there is potential safety hazard.

Utility model content

This utility model is the deficiency for avoiding existing for above-mentioned prior art, provides a kind of transfusion device bottle cork needle, by improving the structure of transfusion device bottle cork needle, reducing medicinal liquid remaining, eliminating safe hidden trouble.

This utility model is that technical solution problem adopts following technical scheme:

The construction features of this utility model transfusion device bottle cork needle is: the total length arranging described transfusion device bottle cork needle is 28mm, and on puncture needle, fluid passage entrance is 12mm apart from Aculeata, and fluid passage entrance is 16mm apart from needle tip.

The construction features of this utility model transfusion device bottle cork needle is also: arranging described fluid passage entrance to needle tip is triangular pyramid.

Compared with the prior art, this utility model beneficial effect is embodied in:

1, this utility model makes fluid passage entrance distance Aculeata on puncture needle for decreasing 6mm, effectively reduce medicinal liquid remnants with this;

2, this utility model makes fluid passage entrance add 6mm apart from needle tip, makes fluid passage entrance more away from needle tip, effectively prevent the crumb of bottle stopper blocking liquid feeder connection formed in puncture process, eliminates safe hidden trouble.

3, in this utility model, fluid passage entrance is triangular pyramid to needle tip, and the seamed edge in triangular pyramid is sharper, makes puncture process more light, also effectively can reduce the generation of crumb of bottle stopper simultaneously, improve safety.

Accompanying drawing explanation

Fig. 1 is this utility model schematic front view;

Fig. 2 is this utility model schematic side view;

Number in the figure: 1 transfusion device bottle cork needle, 2 fluid passage entrances, 3 Aculeatas, 4 needle tips, 5 fluid passages, 6 filters, 7 hand holding handles.

Detailed description of the invention

See Fig. 1, Fig. 2, in the present embodiment, the version of transfusion device bottle cork needle 1 is: the total length arranging transfusion device bottle cork needle 1 is 28mm, and on puncture needle, fluid passage entrance 2 is 12mm apart from Aculeata 3, and fluid passage entrance 2 is 16mm apart from needle tip 4.

Fluid passage entrance 2 to needle tip 4 is set in the present embodiment for triangular pyramid.

The hand holding handle 7 and the filter 6 that are positioned at the afterbody of transfusion device bottle cork needle 1 shown in Fig. 1 and Fig. 2 are conventional setting, and fluid passage 5 is overall through in transfusion device bottle cork needle 1 and hand holding handle 7.

This utility model effectively reduce intravenous pharmacy particularly valuable, small dose drug waste, ensure that the accuracy of patient dosage, ensured the therapeutic effect of patient, prevention infusion reaction, improve patient to the satisfaction of nursery work.Improved procedure of the present utility model is for manufacturer simultaneously, does not need die sinking again, existing mold foundation carries out improvement and can implement to produce, effectively can save the production cost of manufacturer.

Claims
