The specific embodiment mode
Seeing also Fig. 1 to Figure 11, is the selected embodiment of this utility model shown in the figure.
Fig. 2～dosing structure A shown in Figure 4 is to be example with the chemical feed pipe on the conduit 31 of being located at venous transfusion device shown in Figure 11, its composition is to comprise a tool medicinal liquid opening 11 being communicated to the dosing socket 10 of chemical feed pipe 1, and is connected the free end of dosing sockets 10 and constituted an opening by this medicinal liquid opening 11.This opening is the groove seat 12 that an expansion aperture forms, and this groove seat 12 is sealed by a colloid thromboembolism 13.These colloid thromboembolism 13 axial lower surfaces include a deep blind hole 130, and in should blind hole 130 diameter ranges, the upper surface of colloid thromboembolism 13 dissects out the cutting mouth 131 that can be connected with medicinal liquid opening 11.This cutting mouth 131 can be set as the otch of different angles such as " Y " shape, "+" shape, " V " shape, " " shape or " I " shape.
The free end of this dosing socket 10 is in conjunction with a fastener 2, this fastener 2 comprises that an inverted taper hole 21 is positioned at vertical colloid thromboembolism 13 axial upper surface directions, the miner diameter end that this taper hole 21 possesses is towards colloid thromboembolism 13, fastener 2 constitutes a cap 23 at taper hole 21 miner diameter ends, and this cap 23 is placed on this dosing socket 10 free-ended groove seats 12 outsides.Two outward flanges 22 are located at this fastener 2 and are positioned at the bigger diameter end that taper hole 21 possesses and constitute a screw thread rotary lock part.One protective cover 24 is for being socketed on the fastener 2, to cover this taper hole 21 bigger diameter ends.
Groove seat 12 internal diameters of above-mentioned dosing socket 10 be able to closely be inserted for this colloid thromboembolism 13, and the cap 23 that fastener 2 bottoms are provided with, and its internal diameter and the degree of depth then can be overlapped should groove seat 12, and can press against this colloid thromboembolism 13 and can not come off.The ora terminalis of this cap 23 supports to the peripheral set stopper 14 of this groove seat 12, be able to cover whole groove seat 12 fully, and this fastener 2 combines with groove seat 12 and can utilize gummed or high-frequency mode that the two is combined closely.
This utility model can carry out dosing work for a kind of common syringe 40 that is unkitted entry needle shown in Figure 5; Syringe needle conjugation tube 41 with the syringe front end inserts from taper hole 21 in the drawings, and compress the set cutting mouth 131 of colloid thromboembolism 13 upper surfaces, finally back down this cutting mouth 131 and form an opening and clamp the syringe front end, this moment, syringe needle conjugation tube 41 constituted tight socket state with taper hole 21, and firm support syringe front end, so, the nursing staff can inject the medicinal liquid in the syringe 40 in the conduit of venous transfusion device from dosing socket 10.
Figure 6 shows that the sketch map of syringe 40 installations, one plastic safety syringe needle 52 and this utility model dosing respective outer side edges enforcement dosing.
In aforementioned each example, the colloid thromboembolism has good steadiness by the wall height that axially forms along blind hole 130 on every side, therefore when practical application, because of plastic safety syringe needle 52 thick than the common metal syringe needle, or the pipe form of the syringe needle conjugation tube 41 of syringe front end, the pressure in the time of all can not stretching through because of safety needle or syringe needle conjugation tube pushes dosing socket 10 inside with the colloid thromboembolism; On the other hand, after injecting liquid drug is finished, when desiring to extract syringe, though cutting mouth 131 formed a plurality of cutting lobes edges of this colloid thromboembolism 13 still are clamped in the surface of syringe needle conjugation tube 41 or plastic safety syringe needle 52, but, can avoid this colloid thromboembolism 13 to be pulled out and turn up because of the stop effectiveness of cap 23.
Characteristic of the present utility model is, install the syringe needle of any pattern additional or directly use syringe needle conjugation tube 41 (shown in Fig. 5,6,7) on the syringe no matter be, insert or withdrawal process in equal firm safety, this is because the meticulous collocation design of colloid thromboembolism 13 of the present utility model and dosing socket 10 groove seats 12, because these colloid thromboembolism 13 set cutting mouths 131 can strut it because of syringe needle conjugation tube 41 compresses, form a circulation space, can squeeze in view of the above for medicinal liquid.
And what deserves to be mentioned is, when outward flange 22 of the present utility model and interlocking formula shown in Figure 7 (Luer Lock) when syringe 40 cooperates embodiment, because of rotary lock part 401 inside of syringe needle conjugation tube 41 peripheries of this syringe 40 are provided with female thread 402, when so the rotary lock part of syringe 40 revolves lock mutually with outward flange 22, impel syringe needle conjugation tube 41 to compress the set cutting mouth of colloid thromboembolism 13 upper surfaces 131 and form an opening, the mode of revolving lock whereby can more highlight the bonded fixing that accurately reaches of interlocking formula syringe.This outward flange 22 can be so as to fixing syringe simultaneously, and the nursing staff needn't help the pushing syringe by both hands, and can carry out dosing work like a cork.
After dosing was finished, protective cover 24 is the taper hole 21 of stopper fastener closely, and utilized the projection 241 of protective cover inner face to withstand colloid thromboembolism 13, prevented that medicinal liquid from exosmosing.
Fig. 8 is the accurate drip bag 30 top position B that dosing structure of the present utility model is arranged on venous transfusion device shown in Figure 1, Fig. 9 is the transfusion bag position C that this utility model dosing structure is located at the venous transfusion device, these embodiment are as aforementioned functional, convenient nursing personnel dosing operation.
Figure 10 is the sketch map that this utility model dosing structure 80 is arranged at a kind of intravenous injection indwelling equipment 8, this dosing structure 80 is arranged on conduit 812 terminal positions that are connected in a plastics remaining needle 811, its purposes as shown in figure 11, plastics remaining needle 811 on patient's wrist safety pass through dosing structure 80 injectable drugs.
The above, it only is preferred embodiment example of the present utility model, be not that this utility model is done any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment example all still belong in the scope of technical solutions of the utility model.
