Detailed Description
Example 1
Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution:
the utility model provides a pjncture needle for Ommaya bag, including hollow puncture portion 1, hollow flexion 2, hollow connecting portion 3, the one end of puncture portion 1 is provided with a syringe needle 4, the one end and the hose 5 intercommunication of connecting portion 3, the both ends of flexion 2 are linked together with the other end of puncture portion 1 and the other end of connecting portion 3 respectively, the other end of hose 5 is provided with a connector 6, puncture portion 1, flexion 2, the inner chamber of connecting portion 3 communicates in proper order and forms the unanimous drainage tube of a pipe diameter, drainage tube and hose 5 intercommunication, still be provided with a stationary vane 7 on connecting portion 3, the one side of stationary vane 7 is provided with pastes the layer, the another side of stationary vane 7 links to each other with connecting portion 3.
Further, still include a sponge fixed bolster 8, be provided with a through-hole and a logical groove on the sponge fixed bolster 8, lead to the axial of groove setting at a side surface of sponge fixed bolster 8 and perpendicular to through-hole, lead to the edge of groove intercommunication through-hole and sponge fixed bolster 8, syringe needle 4 passes the through-hole, and sponge fixed bolster 8 sets up in the outside of puncture portion 1. Specifically, the sponge fixing pad 8 may be a circle with a diameter of 15mm, a thickness of 2mm, and a diameter of a through hole of 1 mm.
Further, a protection application 9 is included, a blank part and an adhering part are arranged on one side of the protection application 9, the blank part covers the upper side of the bending part 2, and the protection application 9 is arranged on the upper side of the puncture needle. Specifically, the protection patch 9 may be a 15-cmx 15cm square with a 3-cmx 3cm blank area.
Further, the needle 4 is a bevel needle.
Further, the fixed wings 7 are symmetrically disposed at left and right sides of the connecting portion 3.
Furthermore, the bending angle of the bending part 2 is 90 degrees, the length of the puncture part 1 is 12mm or 17mm, the inner diameter of the drainage pipeline is 0.33mm, the outer diameter of the drainage pipeline is 0.64mm, the length of the connecting part 3 is 20mm, and the length of the hose 5 is 10 cm.
The working process of the embodiment is as follows:
the position of the Ommaya sac 10 on the surface of the scalp 11 is firstly positioned, the needle 4 is pricked into the Ommaya sac 10 after disinfection until liquid flows out, then the sponge fixing pad 8 soaked with iodophors in advance is arranged on the periphery of the puncture part 1 through the through groove and the through hole, and the connecting part 3 is fixed on the surface of the scalp 11 through the fixing wing 7 in an adhering mode. Finally, the puncture needle is covered and stuck and fixed by the protective plaster 8. And finally, the drainage collecting device or the infusion device is connected through the connector 6.
The working principle is as follows: the formed puncture needle with the bend not only saves the step of manually bending the straight needle, but also eliminates the possibility of waste products (the puncture needle is broken due to failure of bending, the puncture part 1 is too short to be inserted into the ommaya sac 10, and the length of the scalp outside is too long to cause slippage) caused by overlong puncture part 1), thereby improving the medical efficiency. The puncture needles have consistent inner diameters, so that a narrow pipeline cannot be generated due to manual bending, and the flow speed cannot be influenced. The sponge fixing pad 8 can pre-absorb iodophor, has a disinfection effect on punctured wounds, and plays a role in filling and fixing the indwelling puncture needle. The protective patch 9 can further prevent the puncture needle from coming off.
