Figure 10 is the structural representation of another embodiment of emergency pace-making implanting device.

Figure 11 is the enlarged diagram of syringe needle.

Emergency pace-making implanting device shown in Figure 1 is made of syringe needle 1, needle tubing 3, handle 6, flexible pipe 7, fastening device 8, electrode cable 9, conduit 10, Communicating device 11 and syringe 12.The implantation end of syringe needle 1, needle tubing 3 is to be made by rustless steel.Flexible pipe 7, conduit 8 are silica gel tubes.The junction of needle tubing 3 tail ends, the cap bag 29 of handle 6, fastening device 8, linker 11, syringe 12 are made by plastics.

Handle 6 is cuboid housings that does not wait in footpath, two ends.Have rectangular opening having on the shell wall of boss, at the shell wall face towards rectangular opening is a flank of tooth, on the inwall of rectangular opening both sides, have parallel each other horizontal channel 14, have one one end to have the connection tube 13 of female thread at the middle part of handle 6 miner diameter ends, a circular hole 15 is arranged at the middle part of bigger diameter end.The end of thread of connection tube 13 is connected with needle tubing 3, and the other end is connected with flexible pipe 7.Flexible pipe 7 stretches out (as Fig. 2, shown in Figure 3) from circular hole 15.The fastening device 8 that is contained in the handle 6 is the rollers that roll that have the flank of tooth and central shaft.The central shaft that rolls roller is moving in groove 14, and the spacing of rolling the roller flank of tooth and the shell wall flank of tooth changes with the rolling of rolling roller, and the spacing when promptly rolling roller and rolling forward between two flank of tooth is dwindled, on the contrary then expansion.By the variation of two flank of tooth spacings, reach the locking of electrode cable 9 or unclamp and the sealing of flexible pipe 7 or open-minded.

Needle tubing 3 is that one one distolateral wall has two symmetrical circular holes 2 that are positioned at same radial line, and the other end has the pipe of cross over pipe 5 and connector 4.Its circular hole 2 is implanted 5 to 6 millimeters of end terminations apart from needle tubing 3.The electrode cable 9(that welds together with conical syringe needle 1 is as shown in Figure 4) be that resistance value in the Polyurethane plastic tube 17 is not more than 45 ohm cathode wire 16 and the spring-like positive wire 19 that exposes on Polyurethane plastic tube outer surface constitutes by being located at.The two ends of cathode wire 16 are welded in syringe needle 1 respectively, on the stainless steel lathe dog 21 on the electrode cable 9.End at clip 21 has a stainless steel ring 22.The two ends of positive wire 19 are welded on respectively on the clip 18,20 on the electrode cable 9.Clip 18 is apart from syringe needle 1 about 10 millimeters, and clip 20 is apart from clip 21 about 20 millimeters.Electrode cable 9 is drawn by the flexible pipe 7 of traction steel wire (as shown in Figure 5) in needle tubing 3, handle 6 that an end has hook.And it is inserted in plug connector 25(as shown in Figure 6) in, respectively the cathode and anode lead is connected by knob 26,27.Cathode and anode plug 23,24 is connected with pacemaker.

The end that inputs or outputs of syringe 12 has a sealing plug 28.Syringe 12 was realized with connecting by conduit 10 and Communicating device 11 of needle tubing 3.Communicating device 11 is made of the sealed rubber pipe 31 that is located at the syringe needle 30 in the guard shield 29 and is enclosed within syringe needle 30.When using, by screw thread guard shield 29 is fastened on the syringe 12, syringe needle 30 thrusts in the syringe 12 and UNICOM's (as shown in Figure 7) along with the precession of guard shield 29.

On syringe needle 1 and needle tubing 3, be with protective cover (as Fig. 8, shown in Figure 9).

That shown in Figure 10 is another kind of embodiment of the present utility model.Different is with the foregoing description, and the fastening devices 8 in the handle 6 are levers.It is constituted by being located at the briquetting 36 that stick that has button 32,33 34,35 on the beaming roller and termination have groove.Axostylus axostyle on the beaming roller is installed in the symmetrical holes on handle 6 two sides.On the button hole wall of handle 6, pit is arranged, the projection that adapts with pit is arranged on stick.Control the keying of briquetting 36 by pressing button 32,33.And coincide mutually by projection on the stick and the pit on the hole wall and to limit the position of briquetting 36.
