Detailed Description
The specific structure of the present invention is described in detail with reference to fig. 1 to 6. The thoracoabdominal cavity chemotherapy catheter device comprises an outer layer catheter 1 consisting of an outer catheter main body 5, wherein the outer side of the upper part of the outer catheter main body 5 of the outer layer catheter 1 is provided with a section of adhesive film 2 which is used for positioning the outer layer catheter 1 outside a patient body and clings to the skin around the outside of an opening of the thoracoabdominal wall; and the inner side wall of the lower end of the medicine injection through cavity 9 in the outer catheter main body 5 of the outer catheter 1 is provided with an outer catheter inner wall bulge 10 which is matched, clamped and positioned with a middle catheter outer wall bulge 12 on the outer side wall of the lower end of the middle catheter 3. The upper end of the outer catheter main body 5 is provided with a liquid medicine injection opening 8, and a catheter closing cover 6 which can be opened and closed is arranged at the liquid medicine injection opening 8. In order to facilitate the pulling lead wires at the upper ends of the middle layer catheter 3 and the inner layer catheter 4 to respectively pass through the catheter closing cover 6, the catheter closing cover 6 arranged at the upper end of the outer layer catheter 1 is provided with a pulling wire avoiding notch 7.
A middle layer catheter 3 is inserted in a medicine injection through cavity 9 in the middle of an outer catheter main body 5 of the outer layer catheter 1, and a middle catheter outer wall bulge 12 which is matched and clamped with an outer catheter inner wall bulge 10 in the outer layer catheter 1 is arranged on the outer side wall of the lower end of a middle catheter main body 11 of the middle layer catheter 3; and a middle catheter inner wall bulge 13 which is matched and clamped with an inner catheter outer wall bulge 16 on the outer side wall of the lower end of the inner catheter 4 is also arranged below the middle catheter outer wall bulge 12 and at the lower end of the medicine injection through cavity 9 in the middle catheter main body 11. Meanwhile, the inner layer catheter 4 is inserted into the medicine injection through cavity 9 of the middle catheter main body 11 of the middle layer catheter 3, and the medicine injection through cavity 9 is arranged in the middle of the inner catheter main body 15 of the inner layer catheter 4; the outer side wall of the lower end of the inner conduit main body 15 of the inner conduit 4 is provided with an inner conduit outer wall bulge 16 which is matched and clamped with the middle conduit inner wall bulge 13 in the middle conduit 3. And then through the middle catheter outer wall bulge 12 on the lower extreme lateral wall of the middle catheter 3, with the protruding 10 cooperation joint of the outer catheter inner wall that the cavity 9 lower extreme was led to the injection of outer catheter 1, and the inner catheter outer wall bulge 16 on the lower extreme lateral wall of the inner catheter 4, lead to the protruding 13 cooperation joint of the middle catheter inner wall that the cavity 9 lower extreme was led to with the injection of middle catheter 3, ensure that the inside middle catheter 3 of this pipe installation and inner catheter 4 only can be extracted to the external direction of patient, and can not the landing goes into the patient thorax, use reliability with hoisting device.
It can be understood that, according to specific use requirements, the outer catheter 1, the middle catheter 3 and the inner catheter 4 can adopt an inverted cone-shaped tube structure with a large upper end and a small lower end, so that the catheter device can be conveniently inserted into the pleuroperitoneal cavity of a patient, and further the middle catheter 3 and the inner catheter 4 can be ensured not to accidentally fall into the pleuroperitoneal cavity of the patient. Meanwhile, the lengths of the outer layer conduit 1, the middle layer conduit 3 and the inner layer conduit 4 are sequentially increased from the outer layer to the inner layer, and the diameter of the pipe body is sequentially decreased progressively. In order to facilitate the positioning and clamping between the middle layer conduit 3 and the outer layer conduit 1, and between the inner layer conduit 4 and the middle layer conduit 3, the outer conduit inner wall bulge 10 of the outer layer conduit 1, the middle conduit outer wall bulge 12 of the middle layer conduit 3 and the middle conduit inner wall bulge 13, and the inner conduit outer wall bulge 16 of the inner layer conduit 4 all adopt annular bulge structures. Moreover, for the purpose of facilitating the pulling out of the middle layer catheter 3 from the drug injection through cavity 9 of the outer layer catheter 1 and the pulling out of the inner layer catheter 4 from the drug injection through cavity 9 of the middle layer catheter 3, the upper ends of the middle catheter main body 11 of the middle layer catheter 3 and the inner catheter main body 15 of the inner layer catheter 4 are respectively provided with a middle catheter pulling lead 14 and an inner catheter pulling lead 17 which extend towards the outside of the patient body, so that the device is convenient to use.
When the catheter device for thoracoabdominal cavity chemotherapy is used, first, the lower end of the catheter device is inserted into the thoracic cavity or abdominal cavity through the opening in the thoracoabdominal skin 18 of the patient. Then, the adhesive film 2 arranged on one section of the outer layer catheter 1 positioned outside the patient body is tightly attached to the skin around the outside of the opening of the chest and abdomen wall, so that the adhesive film 2 is attached to the skin, the skin around the opening of the chest and abdomen wall is further prevented from being damaged by the chemotherapeutic drugs, and the catheter closing cover 6 at the upper end of the outer layer catheter 1 is fastened. When in postoperative chemotherapy, the catheter closing cover 6 is opened, and the perfusion liquid medicine 19 is sent into the body of a patient through the liquid medicine injection opening 8 and the medicine injection through cavity 9.
When chemotherapy is performed again and the catheter device is blocked (the inner catheter 4 with the smallest diameter is blocked), the doctor can lift the inner catheter by hand to pull the lead 17, slowly draw the inner catheter 4 out of the drug injection through cavity 9 of the middle catheter 3, and then continue the infusion of the drug solution by using the middle catheter 3 with a larger diameter. If the catheter device is blocked (the middle catheter 3 with larger diameter is blocked) again during the subsequent chemotherapy, the middle catheter is lifted by hand to pull the lead 14, the middle catheter 3 is slowly drawn out from the medicine injection through cavity 9 of the outer catheter 1, and the chemotherapy liquid medicine is continuously fed from the outer catheter 1 with the widest diameter. And after the chemotherapy is finished, the heparin tube is sealed, and the catheter closing cover 6 is tightly covered. The catheter device for thoracoabdominal cavity chemotherapy can ensure three times of effective thoracoabdominal cavity chemotherapy at least once, prevent the liquid medicine from seeping out and damaging surrounding tissues and skin, is convenient for sealing the catheter after the chemotherapy is finished, enables the liquid medicine to be retained in the thoracoabdominal cavity to finish the treatment, and is convenient and reliable to use.
