Description
Technical field
This utility model belongs to medical instruments field, particularly relates to the easy puncture of medicine bottle safety used in a kind of disposable transfusion device and moulds pin greatly.
Background technology
As time goes on, the mankind are constantly developing newtype drug, but threaten the resistance of the various disease of formation of the mankind also in continuous increase, virus is also in continuous variation simultaneously, difficulty is added to the various disease of human treatment, the disease that can treat of often taking medicine in the past now needs intramuscular injection or transfusion to treat, and therefore venous transfusion has become the most common in modern clinical treatment and one of the most effective administering mode.Nurse is when operating to patient infusion, after preparing medicinal liquid, medicine bottle to be inserted in one end of transfusion device, the part that disposable transfusion device inserts medicine bottle is called medicine bottle puncture needle, the medicine bottle puncture needle kind of traditional disposable transfusion device is more, is substantially divided into draw point or plastics pin: the first adopts draw point, though the advantage of draw point easily punctures, but easily come off in infusion process, be oxidized, come off, be oxidized and cause secondary pollution; Second is adopt plastics pin, though plastics pin inserts rear difficult drop-off, when inserting, frictional force is large, not easily punctures, and easily produces bottle stopper material and considers to be worth doing, also easily cause secondary pollution in piercing process; Therefore these two kinds of equal existing defects of medicine bottle puncture needle.In order to overcome the defect of draw point or plastics pin, this utility model dexterity by draw point design moulding the mid portion of pin, carry out steel and mould combination, both original draw point and the advantage of moulding pin had been provided with, compensate for again defect between the two, avoiding comes off in plug bottle process or in infusion process produces the problem of secondary pollution, does not need to use side opening needle for inserting bottle, make the structure of transfusion device more simple after being provided with air cock.
Summary of the invention
The easy puncture of safety that the main technical problems to be solved in the utility model is to provide the use of a kind of disposable transfusion device moulds pin greatly, and this pin is arranged on disposable transfusion device foremost, before transfusion, directly insert medicine bottle, and medicinal liquid is delivered to tube for transfusion; This pin combines single draw point or moulds the advantage of pin, provide that a kind of structure is simple, easy to operate, safety that safety and sanitation and cheap disposable transfusion device use easily puncture mould pin greatly.
This utility model is the technical scheme adopted:
The safety that disposable transfusion device uses easily puncture moulds pin greatly, comprise: metal needle 1, with handles mould needle body 2, air cock 3, tube for transfusion 4, it is characterized in that: metal needle 1 is moulded in the middle of needle body 3 through being connected with tube for transfusion 4 from handles, air cock 3 is provided with in junction, the center of moulding needle body 3 is at metal needle 1, apart from metal needle 1 needle point lower end 1 centimeters, with handles moulds the slope that needle body 2 forms a band tapering, when handle is for transfusion nurse's plug bottle.
Further technical scheme of the present utility model is:
Described metal needle is made up of rustless steel.
It is described that with handles to mould needle body by acrylonitrile-butadiene-styrene copolymer resin be that raw material is made.
Described air cock by valve gap and only liquid film form, outside, only liquid film is arranged in valve gap valve gap, and only liquid film is made up of politef.
The beneficial effects of the utility model are: the easy puncture of safety providing the use of a kind of disposable transfusion device moulds pin greatly, this this dexterity of product by draw point design moulding the mid portion of pin, carry out steel and mould combination, both original draw point and the advantage of moulding pin had been provided with, compensate for again defect between the two, avoid and in plug bottle process, to fall needle for inserting bottle in bits or infusion process come off and produce the problem of secondary pollution.
Accompanying drawing explanation
As shown in Figure 1 be structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail.
1. the easy puncture of safety that disposable transfusion device uses moulds pin greatly, comprise: metal needle (1), with handles mould needle body (2), air cock (3), tube for transfusion (4), it is characterized in that: metal needle (1) is moulded in the middle of needle body (3) through being connected with tube for transfusion (4) from handles, air cock (3) is provided with in junction, the center of moulding needle body (3) is at metal needle (1), apart from metal needle (1) needle point lower end 1 centimeters, with handles moulds the slope that needle body (2) forms a band tapering, when handle is for transfusion nurse's plug bottle; Described metal needle is made up of rustless steel; It is described that with handles to mould needle body by acrylonitrile-butadiene-styrene copolymer resin be that raw material is made; Described air cock by valve gap and only liquid film form, outside, only liquid film is arranged in valve gap valve gap, and only liquid film is made up of politef.
2. before patient infusion, the disposable transfusion device having moulded greatly pin by easily puncturing with safety after nurse has made up a prescription inserts medicine bottle and takes patient at one's side, now open the valve gap of air cock 2, air enters liquid film to end, because of only liquid film has can only function by air not by medicinal liquid, air is by stopping liquid film, enter mould pin inside upwards flow in the medicinal liquid of medicine bottle through metal needle 1, air is formed on the upper strata of medicinal liquid, medicinal liquid also along above-mentioned passage flow downward to end liquid film time, because stopping liquid film not by liquid, medicinal liquid can only continue flowing along tube for transfusion 4 and enter human body.
Certainly, this utility model also has other embodiment, not leaving the improvement of any technology, principle and the technique done under spiritual background of the present utility model, all drops within protection domain of the present utility model.
Claims (4)
