The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing this utility model is described in further detail.Obviously, described embodiment only is this utility model part embodiment, rather than whole embodiment.Based on the embodiment in this utility model, those skilled in the art all belong to this utility model protection domain not making all other embodiment that obtain under the creative work prerequisite.
This utility model provides a kind of infusion plug, comprises the infusion needle 10 with liquid flow hole 14, and described infusion needle 10 outer setting have needle stand 12;
Be provided with 2 root apertures 19 and 2 needle stand holes 17 on the described infusion needle 10, described root aperture 19 and described needle stand hole 17 lay respectively at the upper and lower of described needle stand 12, as shown in Figure 2;
Described infusion needle 10 inside are provided with plug stator 20, as shown in Figure 3, Figure 4, described plug stator 20 is lamellar, top is with 2 fixing protruding medicated caps 29, the bottom is with 2 protruding medicated caps 27 of button, described 2 fixing protruding medicated caps 29 respectively with 2 root apertures, the 19 corresponding settings of infusion needle 10,2 needle stand holes, the 17 corresponding settings of the protruding medicated cap 27 of described 2 buttons and infusion needle 10.
The protruding medicated cap 27 of described button is equal to or higher than described fixing protruding medicated cap 29.
When user mode not, the fixing protruding medicated cap 29 of described plug stator 20 passes the root aperture 19 of infusion needle 10, and the protruding medicated cap 27 of the button of plug stator 20 passes the needle stand hole 17 of infusion needle 10, and plug stator 20 is in natural form.
Described fixing protruding medicated cap 29 heights of projection are than the wall thickness of pipe of infusion needle 10, and preferably, described fixing protruding medicated cap 29 heights of projection are than the wall thickness of pipe 1-5mm of described infusion needle 10.
Preferably, the bossing of described fixing protruding medicated cap 29 is rounded shapes, the fillet design makes the bossing of whole fixing protruding medicated cap 29 appear to the semicircle sphere, can reduce the friction between the wall pipe of fixing protruding medicated cap 29 and infusion needle 10, fixing protruding medicated cap 29 is more convenient for from root the aperture 19 outstanding or retractions of infusion needle 10.
Described plug stator 20 is made by elastomeric material, plastics for example, elastic sheet metal etc.After extruding about plug stator 20 stressed quilts, under the effect of elasticity elastic force, resile.
Preferably, the top is set to sharp structure 22 on the described plug stator 20, as shown in Figure 4, sharp structure 22 not only can make plug stator 20 infusion needle 10 inside of easily packing into, can also increase the elasticity of plug stator 20, help plug stator 20 to accelerate to resile, and the top arrange sharp structure 22 and more is conducive to fixing protruding medicated cap 29 ends and resiles or natural form on plug stator 20.
Described plug stator 20 inside are provided with at least one elasticity and return contrary sheet 25, as shown in Figure 3, Figure 4, described elasticity is returned contrary sheet 25 for than plug stator 20 more plastic sheet or the elastic sheet metal of strong elastic to be arranged, can embed plug stator 20 inside by manufacturing process during fabrication, the effect that elasticity is returned contrary sheet 25 is to increase elastic force, after extruding about plug stator 20 stressed quilts, return under the contrary elastic force effect of sheet 25 in elasticity, accelerate to resile or natural form.
When using, as shown in Figure 5, new clothes or when changing liquid for example, with thumb and the forefinger protruding medicated cap 27 that presses button, pressure-acting forces plug stator 20 cambers, so that in the fixing protruding medicated cap 29 retraction root apertures 19, when the insertion transfusion bag of infusion needle 10/bottle 30, the rubber closure 32 that passes transfusion bag/bottle 30 along with infusion needle 10 enters in transfusion bag/bottle 30, then when decontroling the protruding medicated cap 27 of button, under elastic reaction, plug stator 20 resiles or natural form, so that fixing protruding medicated cap 29 passes root aperture 19 again, because this moment, protruding fixing protruding medicated cap 29 was positioned at because rubber closure 32 tops of transfusion bag/bottle 30, thereby block whole infusion needle 10 not landings, play fixation.
When clinical use, when pressing or decontroling the protruding medicated cap 27 of button, liquid might ooze out in the infusion needle, pollute, be head it off, further, tube wall outer wrap at the infusion needle 10 of the protruding medicated cap of described button 27 positions is provided with liquid sealing parts 40, as shown in Figure 7, described liquid sealing parts 40 are positioned at described needle stand 12 bottoms, the protruding medicated cap 27 of button is sleeved on the outer tube wall of infusion needle 10, wrap the protruding medicated cap 27 of button fully and form liquid sealing, even so that have liquid to ooze out the infusion needle tube wall in the protruding medicated cap of button 27 positions, can effluent seal member 40 and pollute yet, described liquid sealing parts 40 can adopt plastics, the resilient material such as rubber is made.
In this utility model, whole plug stator 20 is laminated structure, when using, as shown in Figure 6, liquid can enter and passes through from the both sides of plug stator 20 from liquid flow hole 14, and the laminated structure design can not hinder liquid communication, and only needs less extruding force, just can make plug stator 20 in infusion needle, form arc, be easy to and be convenient to new clothes or change liquid.
In the prior art, the transfusion device kind is more, each has its distinctive function (such as actuator, lucifuge), and functional type transfusion device expense is higher, if careless the pollution not only affects therapeutic effect, increase the weight of patient's burden, simultaneously environment has also been caused great pollution when chemotherapeutics (particularly).
This utility model is transformed on the basis of common transfusion plug for the plug of transfusion bottle/bag end, at infusion plug 4 apertures is set, and section arranges the plug stator within it, can realize, implementation cost is low, and the scope of application is extensive.
Prior art (such as Chinese utility model patent CN201692431) normally fixes transfusion device at some devices of infusion plug outer setting, owing to can repeatedly install and remove infusion set additional, for clinically when busy (particularly), can there be larger inconvenience in the use, the transfusion inefficiency, and this utility model is that the plug stator is set in infusion needle inside, reach the fixedly purpose of transfusion device by in general infusion device plug, improving, have easy to use, do not affect outward appearance, can significantly save time and reduce pollution, in clinical, have the more widely suitability.
Above illustrated embodiment; the purpose of this utility model, technical scheme and advantage have been carried out further detailed description; institute is understood that; above illustrated embodiment only is preferred implementation of the present utility model; not in order to limit this utility model; all any modifications of within spirit of the present utility model and principle, this utility model being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
