Description
Technical field
The utility model belongs to a kind of transfusion device technical field, and in particular to a kind of medical modified form anti-dropout transfusion device.
Background technology
Transfusion is the conventional disease treatment mode of hospital, and when using, woven hose is syringe needle directly by its pipe end
Insertion infusion bottle.Due to without any fixation, therefore when being acted on by external force, the syringe needle of the woven hose just holds very much
Easily it is separated with infusion bottle mouth, in infusion safety management, syringe needle surprisingly comes off as infusion safety common in clinical transfusion
Problem,
The existing transfusion device of in the market, the overwhelming majority belongs to following a few classes：TPF materials, general infusion set, secondary filter transfusion
Device (including light proofing infusion apparatus).Clinically more is to use precision filter infusion set, because it contains five functional：Be free of
DEHP, prevents from being combined precipitation with liquid；Secondary filter, reduces infusion reaction；Automatic exhaust；Automatic liquid-stopping；Postpone blood back.
Apparent precision infusion set improves many on the basis of original, but it is undeniable be, it is either general
Logical transfusion device, or precision infusion set, there is an inevitable problem, are transfused during liquid using transfusion device, pin
Head drops under external force, there is syringe needle and returns slotting phenomenon.Syringe needle is returned to insert and causes four big main influences：1st, whole bag transfusion causes dirt
Dye, there is the danger of infection；2nd, after contaminated pinhead, waste, the waste of liquid of transfusion device are caused；3rd, the workload of nurse is increased；
4th, the financial burden of patient is increased；5th, conflict between doctors and patients are increased.
Utility model content
Technical problem to be solved in the utility model is directed to above-mentioned the deficiencies in the prior art and provides a kind of medical improvement
Type anti-dropout transfusion device, its simple structure is with low cost, easy to use, solves syringe needle accident obscission.
To realize above-mentioned technical purpose, the technical scheme that the utility model is taken is：
A kind of medical modified form anti-dropout transfusion device, wherein：Including syringe needle, push rod, plastic cap, button, connecting rod, kelly and
Back-moving spring, described syringe needle is fixedly mounted in plastic cap, and described syringe needle outer surface is provided with groove, and described kelly leads to
Rotating shaft is crossed in the groove of syringe needle, described connecting rod one end is hingedly mounted on kelly, and the described connecting rod other end is hinged
On push rod, described push rod is arranged in the mounting hole of plastic cap and push rod is moved up and down along the mounting hole of plastic cap,
Described back-moving spring is arranged on push rod and back-moving spring upper end is withstood on the boss of push rod, described back-moving spring lower end top
On the step of plastic cap mounting hole, described push rod is provided with bellmouth, and the radial direction that described button is arranged on plastic cap is pacified
In dress hole, described button bottom is arranged in the bellmouth of push rod.
It is optimization above-mentioned technical proposal, the concrete measure taken also includes：
The external cylindrical surface of above-mentioned plastic cap is provided with annular boss.
Above-mentioned kelly is arranged on syringe needle using fish hook reversed acanthoid.
Above-mentioned button upper side uses cone structure form near bottom.
After syringe needle for transfusion device insertion infusion bottle, button is pressed, now button slope driving push rod is moved upwards, so as to promote
Kelly opens, kelly such as fish hook reversed acanthoid, it is difficult to extract.Button is installed in syringe needle lower edge, nurse's pressing button, presses when pulling out pin
Button is upspring, and now push rod is moved downward under the elastic force effect of back-moving spring, and push rod drives kelly to draw in by connecting rod, now just
Syringe needle can be easily pulled up, it is swift and convenient to operate.
The utility model simple structure, it is easy to operate, it is stable and reliable for performance；Using kelly, it is to avoid what unexpected syringe needle came off
Occur, improve the security of transfusion, effectively protect the safety of patient.
