Hereinafter with reference to accompanying drawing, described in detail by way of example and provided by the inventionly realize multiduty injector needle cap.It should be noted that at this, the explanation for these way of example understands the present invention for helping, but does not form limitation of the invention.
Various technology described herein may be used for but be not limited to medical instruments field, can also be used for other similar field.
Term "and/or" herein, it is only a kind of incidence relation describing affiliated partner, three kinds of relations can be there are in expression, such as, A and/or B, can represent: individualism A, individualism B, there are A and B tri-kinds of situations simultaneously, herein term " or/and " be describe another kind of affiliated partner relation, can there are two kinds of relations in expression, such as, A is or/and B, can represent: individualism A, individualism A and B two kinds of situations, in addition, character "/" herein, general expression forward-backward correlation is to liking a kind of "or" relation.
Embodiment one, Fig. 1 shows the sectional view of the pin cap that the present embodiment provides.Describedly realize multiduty injector needle cap, comprise pin cap body 1, it is characterized in that: described pin cap body 1 comprises the pin cap baffle plate 2 be positioned at bottom pin cap body 1, be positioned at the pin cap cylinder 3 in the middle part of pin cap body 1, be positioned at the pin cap 4 at pin cap body 1 top; Described pin cap 4 is provided with air-vent 5, and pin cap 4 is built-in with gas-liquid separation membrane 6 with the junction of pin cap cylinder 3, is provided with fixing rubber closure 7, forms a cavity 8 for receiving medical liquids between gas-liquid separation membrane 6 and rubber closure 7 in pin cap cylinder 3.As shown in Figure 1, described injector needle cap can play different effects two different phases: on the one hand, syringe needle can be inserted in injector needle cap, make the tip portion of syringe needle be arranged in rubber stopper 7 or be arranged in cavity 8 through rubber stopper 7, this stage injection device pin cap to syringe needle play protection and fungi-proofing effect (antibacterial in the external world or the volume of virus larger, do not enter into cavity by gas-liquid separation membrane, thus can avoid infection be arranged in cavity, the tip portion of syringe needle), on the other hand, when auxiliary syringe aerofluxus, injectable device syringe needle is inserted in injector needle cap again, make the tip portion of syringe needle through rubber stopper 7, and enter into cavity 8, then pushing syringe piston, the gas in injector syringe and part medicinal liquid is made to be squeezed in cavity 8, utilize the filtration of gas-liquid separation membrane 6, gas in cavity 8 is discharged outside to, until cannot pushing syringe piston, now show cavity 8, medicinal liquid has been crowded with in injector syringe and syringe needle, and air is all drained, then extract syringe needle can directly inject, can auxiliary syringe aerofluxus at this stage injection device pin cap, simple to operate, easy to use, and the cavity 8 utilizing capacity to fix limits the dosage that medicinal liquid is emerged from syringe needle, open the effect that aerofluxus economizes medicine, a small amount of medicinal liquid of simultaneously emerging is stored in the cavity in pin cap, can not spill, convenient recycling, thus ensure the cleaning of application scenarios.
Concrete, the distance between axles of described cavity 8 is not less than 2mm and is not more than 6mm.When arranging the distance between axles of cavity 8, its lower limit need guarantee the tip portion can holding syringe needle 5, and its higher limit need consider the dosage allowing medicinal liquid to emerge from syringe needle when aerofluxus, and as what optimize, in the present embodiment, the distance between axles of described cavity 8 is set to 4mm.For the pin cap cylinder 3 that diameter is 3mm, the capacity of cavity 8 is about 28 microlitres, and the liquid dose of emerging during aerofluxus only has half size (the volume size of a usual water is 40 ~ 50 microlitres), saves the successful of medicinal liquid.
Concrete, the thickness of described gas-liquid separation membrane 6 is not less than 0.6mm and is not more than 1.5mm.Described gas-liquid separation membrane 6 is made up of waterproof ventilative material, can divided gas flow and medicinal liquid, and it can be, but not limited to the beautiful board gas-liquid separation membrane in east adopting Rui Sen waterproof ventilative material company limited to produce.When arranging the thickness of gas-liquid separation membrane 6, the robustness of gas-liquid separation membrane 6 when its lower limit need guarantee aerofluxus, its higher limit need consider manufacturing cost, and as an example, in the present embodiment, the thickness of described gas-liquid separation membrane 6 is 1mm.
Concrete, the thickness of described rubber closure 7 is not less than 5mm and is not more than 10mm.Described rubber closure 7 is made up of water proof vapour barrier, can prevent extraneous gas from entering cavity 8 and preventing the medicinal liquid in cavity 8 from oozing out.When arranging the thickness of rubber closure 7, its lower limit need guarantee the water proof trapping effect of rubber closure, and its higher limit need consider the complexity that pierced through by syringe needle 5 and manufacturing cost, and as an example, in the present embodiment, the thickness of described rubber closure 7 is 8mm.
Concrete, described pin cap 4 is hemispherical dome structure or regular polygon frustum structure.As an example, in the present embodiment, as shown in Figure 1, described pin cap 4 is hemispherical dome structure, can directly mate with the pin cap cylinder of drum.
Concrete, described air-vent 5 is positioned at the axle center place on pin cap 4 top.Air-vent 5 is arranged on the axial line place on pin cap top, when aerofluxus, the air-flow of discharge can be made the most smooth and easy, effect is optimum.
Concrete, described pin cap cylinder 3 is transparent socket.Pin cap cylinder 3 is set to transparent tube, and observable syringe needle inserts the situation of injector needle cap, uses more convenient.
What above-described embodiment provided realizes multiduty injector needle cap, has following beneficial effect: (1) described injector needle cap can play protection and fungi-proofing effect to syringe needle, safety and sanitation; (2) described injector needle cap is when auxiliary syringe aerofluxus, simple to operate, easy to use; (3) described injector needle cap is when auxiliary syringe aerofluxus, the gas-liquid separation membrane be beneficial in pin cap realizes being separated of gas and medicinal liquid, and by the fixed capacity of setting cavity, the dosage that when can be limited to aerofluxus, medicinal liquid is emerged from syringe needle, thus reduce the waste of medicine, save medical treatment cost; (4) described injector needle cap is after auxiliary syringe aerofluxus, and a small amount of medicinal liquid of emerging, by the cavity that is stored in pin cap, can not spill, convenient recycling, thus ensures the cleaning of application scenarios.
As mentioned above, the present invention can be realized preferably.For a person skilled in the art, according to instruction of the present invention, design and multi-form realize multiduty injector needle cap.Without departing from the principles and spirit of the present invention these embodiments changed, revise, replace, integrate and modification still falls within the scope of protection of the present invention.
