The specific embodiment
As Fig. 1-shown in Figure 4, first embodiment of a kind of disposable use periphery sleeve pipe transfusion device of the present invention, comprise venipuncture needle assembly 1, conduit tube component 2, liquid medicine filter 3, flow regulator 4, drip kettle 5 and bottle plug puncture unit 6 and air inlet pipe air filter 7, on the feed liquor port 23 of the catheter block 22 of conduit tube component 2 by infusion tube 9 connect successively liquid medicine filter 3, flow regulator 4, drip kettle 5 and bottle plug puncture unit 6, connect air filter 7 in a side of this bottle plug puncture unit 6 by air inlet pipe.Flexible pipe 9 between conduit tube component 2 and the liquid medicine filter 3 is provided with flow-stopping clip 10.
Referring to Fig. 2 and Fig. 3, described conduit tube component 2 comprises catheter block 22, conduit 21, batching pig 24, conduit fixed core 25, side at catheter block 22 is provided with the branch support interface as feed liquor port 23, constitute y-shaped transparent three-port structure, in catheter block 22, has the cavity that arranges vertically, the front end of catheter block 22 is by conical catheter fixed core 25 connecting ducts 2, and conduit 2 is communicated with the cavity front end (being the lower end among Fig. 3) of catheter block 22, and conduit 21 is provided with the development line.Fill in batching pig 24 in the rear port of catheter block 22, and batching pig 24 flows out a bit of distance (end at catheter block 22 forms a groove) apart from the end of catheter block 22.Be provided with feed liquor port 23 at the middle part of catheter block 22.
Referring to Fig. 2 and Fig. 4, described venipuncture needle assembly 1 comprises the draw point seat 12 of draw point 11 and draw point end, is provided with at draw point seat 12 and holds needle handle 13.The front end of draw point seat 12 (lower end among Fig. 4) is provided with cylindrical positioning convex 14, is used for embedding ordinatedly in end (being the upper end of Fig. 3) mouth of catheter block 11.
During use, the tip of described draw point 11 is along cavity and conduit 21 back stretch out from the lower end (referring to Fig. 2) of axially passing batching pig 24, catheter block 22 from the catheter block end of catheter block 22.Venipuncture needle assembly 1 is formed the bushing type venipuncture needle with conduit tube component 2, and its operation principle is:
Before the puncture, the cylindrical positioning convex of draw point seat 12 14 embeds in the end port of catheter blocks 22, and the tip of the draw point 11 on the draw point seat 12 can axially stretching out after the end of catheter block pass cavity in batching pig 24, the catheter block 22 and conduit 21 along catheter block 22.
After the puncture, conduit 21 together enters vein with draw point 11, extract draw point 11 after, conduit 21 is stayed intravenous, medicinal liquid enters vein by the infusion channel that is made of flexible pipe 9, catheter block 22, conduit 21.
Among the above embodiment, the feed liquor port 23 of catheter block 22 directly connects as one by the port of export of flexible pipe 9 with liquid medicine filter 3.
Referring to Fig. 5, the feed liquor port 23 of catheter block 22 also can be connected indirectly with liquid medicine filter 3, namely is connected indirectly by jointing 8 between the feed liquor port 23 of catheter block 22 and the liquid medicine filter 3, and syndeton is detachable.
Referring to Fig. 6, described jointing 8 is two pass joints, and wherein the interface of lower end is for going out liquid interface 82, and the interface of upper end is feed liquor interface 81, is provided with the flat grip 83 of global formation at the middle part.The liquid interface 82 that goes out of jointing 8 directly is connected with the feed liquor port 23 of catheter block 22 by flexible pipe 9, and the feed liquor interface 82 of jointing 8 is equipped with and covers formula sealing cap 84, fills in any one in formula sealing cap 85 or the calparine cap 86.The effect of its middle cover formula sealing cap 84 is exactly after pulling out liquid medicine filter 3 the feed liquor sealing joint of jointing 8 to be lived.
The feed liquor interface 81 of Fig. 6 and jointing 8 shown in Figure 7, (unloading drop cover sealing cap 84 backs) can be connected with liquid medicine filter 3 liquid outlets, and the sealings of the feed liquor interface 81 of joints 8 are realized in the formula that closes the lid sealing cap 84 backs.
The feed liquor interface 81 of the jointing 8 of present embodiment can adopt Rule female cone joint design, and liquid medicine filter 3 liquid outlets adopt Rule outer cone joint design that cooperates with feed liquor interface 81 to interconnect and conducting.Also can adopt Rule outer cone joint design to be connected between lid formula sealing cap 84 and the jointing 8.
As shown in Figure 8, the feed liquor interface 81 of the jointing 8 of band plug formula sealing cap 85 can also be connected and sealed with plug formula sealing cap 85.Plug formula sealing cap 85 comprises the locking cap 852 of software sealing-plug 851 and center drilling, feed liquor interface 81 inner chambers of jointing 8 are made step-like (hole enlargement), software sealing-plug 851 is built in this step-like inner chamber, both locate with concaveconvex structure 853 clampings outside the feed liquor interface 81 of jointing 8 locking cap 852(to be installed then), software sealing-plug 9b1 carries out spacing.
Simultaneously, when adopting the jointing 8 of band plug formula sealing cap 85, liquid medicine filter 3 outlets are connected with can pass software sealing-plug 851 and enter scalp acupuncture (not shown) in the jointing 8.Therefore, the jointing 8 of being furnished with plug formula sealing cap 85 transfusion device or the syringe that can be directly used in the conventional belt scalp acupuncture connects.
As shown in Figure 9, the jointing 8 feed liquor interfaces 81 that calparine cap 86 is housed are connected with calparine cap 86 to cooperate and realize sealing.Calparine cap 86 is the known features of medical apparatus and instruments, just repeats no more here.
Simultaneously, when employing is furnished with the jointing 8 of calparine cap 86, need be connected with on the liquid medicine filter 3 and can passes calparine cap 86 and enter scalp acupuncture (not shown) in the jointing 8.Also can adopt the inside and outside cone joint structure in Rule to be connected sealing between the feed liquor interface 81 of the jointing 8 of present embodiment and the calparine cap 86.
The structure that it will be understood by those skilled in the art that above-mentioned jointing 8 only is exemplary, is not circumscribed.For example: jointing 8 also can adopt three-port structure as shown in figure 10, and one of them interface is for going out liquid interface 82, in addition two interfaces 81 and 81 ' as the feed liquor interface.The liquid interface 82 of going out of jointing 8 directly is connected with the feed liquor port 23 of catheter block 22 by flexible pipe 9, and two feed liquor interfaces of jointing 8 can mounting cover formula sealing cap 9a, fill in any two kinds among formula sealing cap 9b or the calparine cap 9c.The two feed liquor interfaces 81 and 81 of jointing 8 among Figure 10 ' difference mounting cover formula sealing cap 84 and calparine cap 85 can be connected with the needle-free transfusion device with band pin type transfusion device respectively, enlarges the scope of application.
