Description
Technical field
This utility model relates to a kind of medical infusion adjusting device.
Background technology
In the process of clinical vein transfusion, a lot of medicines need accurately control and regulating transfusion precision, and can change at any time original transfusion precision by the needs by the state of an illness and medicine in infusion process.
The infusion adjusting device of existing a kind of controlled drop weight of medicament liquid processed as shown in Figure 1, it comprises lancet and means 91, bumper block 92, cushion 93 and dropping funnel 94.Lancet and means 91 comprises a pedestal 911 and a puncture needle 912, and puncture needle 912 is arranged on the pedestal 911.Pedestal 911 comprises a top board 913 and from the bottom surface of this top board to the annular skirtboard 914 of downward-extension.The lower end of dropping funnel 94 is provided with medicine liquid outlet 95.Bumper block 92 is arranged on the upper end of dropping funnel 94, and the top of bumper block 92 is provided with annular flange flange 921, and the bottom surface of this annular flange flange 921 is supported on the upper surface of dropping funnel 94.Annular skirtboard 914 is around this annular flange flange 921.
In conjunction with Fig. 3 and shown in Figure 4, offer a cavity 920 at the top of this bumper block 92, cushion 93 is arranged in this cavity 920.The bottom of bumper block 92 is provided with mutually different three droppers 922 of drop weight of medicament liquid, 923 and 924, and dripping of the medicinal liquid that flows out from these three droppers heavyly for example is respectively 10 droplets/milliliter, 15 droplets/milliliter and 60 droplets/milliliter.Be provided with and these three droppers 922,923 and 924 three inlet openings 925,926 and 927 of corresponding connection one by one at the diapire of the cavity 920 of bumper block 92.
Extremely shown in Figure 7 in conjunction with Fig. 5, cushion 93 is provided with the flow channel for liquids 930 that connects at the cushion thickness direction, this flow channel for liquids comprises the first opening 931 of being opened on the cushion end face, be opened on the second opening 933 of cushion bottom surface and be communicated with centre bore 932, the first openings 931 of the first opening 931 and the second opening 933 and the external diameter of the second opening 933 all greater than the aperture of centre bore 932.Around the first opening 931, be provided with sealing ring 934, around the 3rd opening 933, be provided with sealing ring 937, be respectively equipped with a projection 939 in the both sides of sealing ring.The pedestal 911 of lancet and means 91 is connected with cushion 93, and can drive cushion 93 in cavity 920 interior rotations.In one embodiment, in conjunction with shown in Figure 2, end face at cushion 93 is provided with three the first blind holes 935 and one second card column 936, be provided with one second blind hole 916 in the bottom surface of the top board of pedestal and to three the first card columns 915 of downward-extension, three the first card columns 915 are embedded in three the first blind holes 935, and the second card column 936 is embedded in the second blind hole 916.It is stressed uniformly that said structure can make cushion 93 obtain when rotating.
The flow channel for liquids of cushion 93 with the rotation of lancet and means 91 optionally with bumper block cavity diapire on one of them inlet opening form path, the inlet opening on the flow channel for liquids of the medicinal liquid that flows into from puncture needle 912 by cushion, the selected bumper block cavity diapire that forms path and the dropper corresponding with this selected inlet opening that forms path flow in the dropping funnel 4.Because the peripheral outer wall at cushion 93 is provided with sealing ring 938, so can guarantee between the perisporium of cushion outer wall and cavity, leakage or gas leak phenomenon can not occur when cushion rotates.Operate for the ease of the user, side face in the annular flange flange 921 of bumper block is provided with three each other with 120 ° of recesses that stagger 928, inwall at the annular skirtboard 914 of lancet and means is equipped with three each other with 120 ° of grabs that stagger 918, and these three grabs 918 are embedded in respectively in three recesses 928.When the user rotates lancet and means, these three grabs 918 also rotate thereupon, the user can obviously distinguish grab in recess and the two states of grab when not dropping in the recess, and drop into three recesses 928 when interior when these three grabs 918, also just meaning has an inlet opening to be accurately positioned unlatching.In addition, on annular skirtboard 912, also be provided with a breach 919, indicate corresponding to the position of this breach 919 on the side face of bumper block 92 and drip a tuple value labelling, for example 10 droplets/milliliter, 15 droplets/milliliter and 60 droplets/milliliter, selected what open is the dropper of any weight so that the user understands.
The shortcoming of existing infusion adjusting device is, when cushion 93 turns to the half-open position of certain inlet opening (this sentences inlet opening 926 and illustrates) with lancet and means 91, as shown in Figure 8, the part of inlet opening 926 is positioned at the zone 9371 that the periphery by sealing ring 937 surrounds, and another part is positioned at outside the zone 9371, at this moment, the medicinal liquid that flows out from the second opening 933 is owing to can not get good sealing, except meeting flow in the inlet opening 926, also can flow in inlet opening 925 and 927, cause thus the sinuous flow phenomenon, medicinal liquid can flow into dropping funnel 94 from three droppers simultaneously, thereby the shape of uncontrollable medicinal liquid drippage weighs with dripping.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of infusion adjusting device of controlling drop weight of medicament liquid, it can be guaranteed when cushion turns to the half-open position of arbitrary inlet opening, the medicinal liquid that flows into from puncture needle only can flow in the dropper that is communicated with this inlet opening, can not flow into other dropper, avoid occuring the sinuous flow phenomenon.
The technical scheme that this utility model adopts is: a kind of infusion adjusting device of controlling drop weight of medicament liquid comprises lancet and means, bumper block, cushion and dropping funnel; Lancet and means comprises pedestal and puncture needle, and puncture needle is arranged on this pedestal; Bumper block is arranged on the upper end of described dropping funnel, and the top of bumper block is provided with a cavity, and the bottom of bumper block is provided with many droppers, is provided with respectively and these many droppers a plurality of inlet openings of corresponding connection one by one at the cavity diapire of bumper block; Cushion is arranged in the cavity of bumper block, and cushion is provided with the flow channel for liquids that connects at the cushion thickness direction, and this flow channel for liquids comprises the first opening of being located at the cushion end face and the second opening of being located at the cushion bottom surface; The bottom surface of cushion is provided with the main seal ring of a projection, and this main seal ring is around the periphery of this second opening; The pedestal of lancet and means is connected with cushion, and can drive cushion and rotate in this cavity; Be characterized in, on the bottom surface of described cushion at least one side of described main seal ring be provided with projection from sealing; Should form sealing area from sealing and described main seal ring, perhaps, should form sealing area from the cavity sidewalls of sealing and described main seal ring and bumper block; The sealing zone can be when cushion turns to the half-open position of any one inlet opening, and the liquid that prevention is flowed out from the second opening flows into other inlet opening; The half-open position of inlet opening refers to that the part of this inlet opening is positioned at the zone that the periphery by main seal ring surrounds, and another part of this inlet opening is positioned at outside the described zone.
Because at least one side at the main seal ring of cushion has also been set up from sealing, should from sealing and main seal ring or with the cavity sidewalls formation sealing area of main seal ring and bumper block, when no matter cushion turns to the half-open position of arbitrary inlet opening, the sealing zone can both stop the liquid that flows out from the second opening to flow into this inlet opening other inlet opening in addition, thereby has avoided the generation of sinuous flow phenomenon.
