Embodiment 1

[0022] A 3D printed vaginal thermoperfusion aid, comprising an integrally formed drug guiding rod 1 and wings 2, the drug guiding rod 1 is in the shape of a column as a whole, and the axial direction of the drug guiding rod 1 is provided with a channel for penetrating a urinary catheter. The hole 11 and the wing 2 are arranged on the side wall of the medicine guiding rod 1 .

[0023] In this specific embodiment 1, the shape of the through hole 11 is elliptical, and the drug guide rod 1, the wing 2 and the blocking block 3 are all printed by PC through 3D, and of course they can also be ABS, PA, PPFS, PEEK , EP, PLA, PETG, PCL, PAA, PU or epoxy resin through 3D printing.

Embodiment 2

[0025] Others are the same as in Embodiment 1, the difference is that a blocking block 3 is integrally formed between the side wall of the proximal end of the medicine guiding rod 1 and the wings 2, the proximal end of the medicine guiding rod 1 has a concave top 12, and the wings 2 are opposite to each other. The two sides of both sides are arc-shaped, and the edges are uniformly formed with retaining strips 21 .

[0026] When in use: the medical staff pushes the proximal end of the drug guide rod 1 into the patient's vagina, and then passes one end of the urinary catheter (not shown in the figure, which is common in the market) through the through hole 11, and the urinary catheter The balloon on the top is stuck in the top 12 of the concave surface, and medicine is sprayed into the vagina through the catheter, which can effectively prevent the medicine liquid from flowing out.

Abstract

The invention relates to the technical field of medical instruments, and in particular to a 3D printing vaginal thermal perfusion auxiliary device. The auxiliary device comprises an integrally formeddrug guide rod and a protective wing, wherein the drug guide rod is in a cylindrical shape, a through hole for penetrating into a catheter is formed in an axial penetration direction of the drug guiderod, and the protective wing is arranged on a side wall of the drug guide rod. The auxiliary device solves a problem that when a patient performs thermotherapy, medicine needs to be administered intothe vagina of the patient, and liquid medicine injected into the vagina easily flows out. The auxiliary device has simple structure and is convenient for wide popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D printed vaginal heat perfusion aid. Background technique [0002] Tumor hyperthermia refers to the application of different heat sources (radio frequency, microwave, ultrasound, laser, etc.) to heat up the temperature of tumor tissue to the effective treatment temperature, causing tumor cell death without damaging normal cells. Hyperthermia can be combined with chemotherapy for patients who have no obvious curative effect of chemotherapy alone, patients who relapse after chemotherapy and receive second chemotherapy, and those who cannot tolerate the dose of conventional chemotherapy. The principle of hyperthermic perfusion chemotherapy is to use physical energy to heat chemotherapeutic drugs with good thermal effects, and infuse them into the tumor site, so that the temperature of tumor tissue rises to the effective therapeutic temperature for 60-120 minutes, so as t...
