The specific embodiment

Fig. 1 is the structural representation of this utility model PCI sacculus silk-guiding conductor.As shown in Figure 1, the agent structure of PCI sacculus silk-guiding conductor comprises the fixing port 10 and the guiding port 20 of connection, and wherein fixing port 10 is used for fixing the PCI foley's tube, and guiding port 20 is used to guide seal wire to enter PCI foley's tube 30.Further, be communicated with by connected chamber 30 between fixing port 10 and the guiding port 20.The internal diameter of fixing port 10 and shape are consistent with shape, the size (size after sacculus is folding) of PCI foley's tube, and guiding port 20 is the taper mouth, and the osculum end of taper mouth is communicated with fixing port 10 by connected chamber 30.In actual use, the cross sectional shape of taper mouth can be circular or oval, also can be made of other regular segmental arcs, and the width of taper mouth big opening end enters the PCI foley's tube more than or equal to 4mm with convenient guiding seal wire.

This utility model PCI sacculus silk-guiding conductor by the fixing PCI foley's tube is set fixing port and the guiding port structure of taper, the PCI foley's tube can be fixed and locatees on the one hand, can guide the seal wire rapid alignment on the other hand and enter the PCI foley's tube, the medical worker can finish seal wire and place in the several seconds, make clinical PCI operation more quick, convenient, safety and reliable, simplified medical worker's labor intensity greatly, improved efficient, removed the puzzlement in medical worker's operation, ensure the valuable emergency call salving time to greatest extent, made contribution for healing the wounded and rescue the dying.

Fig. 2 is the structural representation of this utility model PCI sacculus silk-guiding conductor first embodiment.As shown in Figure 2, in the present embodiment, the PCI sacculus silk-guiding conductor is made up of top and lower part, wherein top is made of last fixing port 11, last connected chamber 31 and last guiding port 21, the lower part is made of following fixing port 12, following connected chamber 32 and following guiding port 22, and top and lower part snap together the PCI sacculus silk-guiding conductor that forms present embodiment.

Fig. 3～Fig. 6 is the use sketch map of this utility model first embodiment.At first top and lower part are snapped together, form fixing port 10, connected chamber 30 and guiding port 20, during fastening PCI foley's tube 40 is arranged between fixing port and the following fixing port, makes PCI foley's tube 40 be positioned at fixing port 10 and fixing (as shown in Figure 3); Then seal wire 50 is transmitted to PCI foley's tube 40 directions from guiding port 20, because guiding port 20 collar extensions are broad, seal wire 50 can enter easily and need not painstakingly aim at, when seal wire 50 touches guiding port 20 inwalls, because of elasticity turns to along wall, send (as shown in Figure 4) before the continuation; Seal wire 50 slips into connected chamber 30 immediately, and enters by connected chamber 30 in the guide cavity of PCI foley's tube 40, and connected chamber 30 guarantees that the progressive direction of seal wire can not change along with the action of medical worker's hands, conveniently inserts (as shown in Figure 5); After seal wire 50 is successfully inserted PCI foley's tube 40, keep seal wire 50 invariant positions, with the top of present embodiment PCI sacculus silk-guiding conductor and lower part separately, promptly finish and wear seal wire operation (as shown in Figure 6).Present embodiment PCI sacculus silk-guiding conductor is reused design for the sterilization back, and easy and simple to handle, cost is low, and is applied widely.

Fig. 7 is the structural representation of this utility model PCI sacculus silk-guiding conductor second embodiment.As shown in Figure 7, in the present embodiment, the PCI sacculus silk-guiding conductor is by the fixing port 10, connected chamber 30 and the guiding port 20 that the are communicated with structure that forms a whole, and fixing port 10, connected chamber 30 and guiding port 20 are provided with tears seam 60, tears seam 60 and is used for making after wearing the seal wire end of operation present embodiment PCI sacculus silk-guiding conductor to break away from PCI foley's tube and seal wire.

In use, at first the PCI foley's tube is fixed in the fixing port, wears the seal wire operation then, after seal wire successfully penetrates, present embodiment PCI sacculus silk-guiding conductor is disintegrated, promptly finish and wear the seal wire operation by tearing seam.Further, present embodiment PCI sacculus silk-guiding conductor can be arranged to integrative-structure with the PCI foley's tube, with the directly fixing sacculus end that is contained in the PCI foley's tube in advance of present embodiment PCI sacculus silk-guiding conductor, packs in the lump, sterilizes with sacculus before promptly dispatching from the factory.During use, after tearing the aseptic packaging of PCI foley's tube, the medical worker as required, seal wire inserted foley's tube easily by present embodiment PCI sacculus silk-guiding conductor after, make the PCI sacculus silk-guiding conductor leave the PCI foley's tube can to treat by tearing seam.The PCI sacculus silk-guiding conductor of present embodiment is disposable design, and the PCI sacculus is transported and storage plays the better protect effect, also can not cause the sacculus distortion and damages.

This utility model is simple in structure, and easy, with low cost, the easy realization of manufacturing process has crucial meaning for the improvement and the use of PCI sacculus.

It should be noted that at last: above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
