Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a 3D-printed vaginal thermal irrigation aid. Background Technology

[0002] Tumor hyperthermia refers to a treatment method that uses different heat sources (radiofrequency, microwave, ultrasound, laser, etc.) to raise the temperature of tumor tissue to an effective therapeutic temperature, causing tumor cell death without damaging normal cells. Hyperthermia can be combined with chemotherapy for patients whose chemotherapy alone is ineffective, patients who require secondary chemotherapy after relapse, and patients who cannot tolerate conventional chemotherapy doses. The principle of hyperthermic perfusion chemotherapy is to use physical energy to heat chemotherapy drugs with good thermal effects and perfuse them into the tumor site, raising the tumor tissue temperature to an effective therapeutic temperature for 60-120 minutes, thus destroying tumor cells without damaging normal tissue. Hyperthermic perfusion chemotherapy can directly increase the concentration of anticancer drugs in the cavity, reduce the concentration of drugs in the systemic circulation, increase the local cytotoxic effect of the lesion, and reduce systemic adverse reactions. Vaginal hyperthermic perfusion chemotherapy is one of the important means of treating primary or secondary vaginal tumors. To maintain the chemotherapy drugs in the vagina for as long as possible to achieve better therapeutic effects, 3D printing technology can be used to print vaginal implants suitable for individual patients based on the degree of vaginal expansion. Summary of the Invention

[0003] The technical problem this invention aims to solve is the issue of leakage of medication injected into the vagina during hyperthermia treatment. This invention provides a solution comprising an integrally molded medication guide and protective wings. The medication guide is cylindrical in shape, with an axial through-hole for inserting a urinary catheter. The protective wings are located on the side wall of the medication guide. This effectively solves the problem of leakage of medication injected into the vagina during hyperthermia treatment.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a 3D printed vaginal thermal irrigation aid, including an integrally formed drug guide rod and protective wings. The drug guide rod is cylindrical in shape, and an axial through hole for inserting a urinary catheter is provided on the drug guide rod. The protective wings are provided on the side wall of the drug guide rod.

[0005] Specifically, a sealing block is integrally formed between the proximal sidewall of the delivery rod and the protective wing. Based on ergonomic design, the sealing block is incorporated to conform to the patient's vulva and further prevent leakage of the medication administered into the vagina.

[0006] Specifically, the sealing block has a smooth, curved surface. Ergonomically designed, the sealing block conforms to the patient's vulva to prevent medication leakage.

[0007] Specifically, the proximal end of the delivery rod has a concave tip. Because there is a balloon on the catheter, it is difficult for the catheter and the delivery rod to adhere properly. By providing a concave tip at the proximal end of the delivery rod, the balloon can be secured within the concave tip, facilitating a better fit between the catheter and the delivery rod.

[0008] Specifically, the opposing sides of the protective wings are arc-shaped, and each edge is integrally formed with a retaining strip. By setting the retaining strip, the contact area between the sides of the protective wings and the patient's skin can be increased, thereby increasing comfort.

[0009] Specifically, the through hole is circular or elliptical in shape.

[0010] Specifically, the drug delivery rod, protective wings, and sealing block are all made of ABS, PA, PC, PPFS, PEEK, EP, PLA, PETG, PCL, PAA, PU, ​​or epoxy resin by 3D printing.

[0011] The beneficial effects of this invention are:

[0012] (1) The present invention provides a 3D printed vaginal hot irrigation aid, including an integrally formed drug guide rod and a protective wing. The drug guide rod is cylindrical in shape, and the axial direction of the drug guide rod is provided with a through hole for inserting a urinary catheter. The protective wing is set on the side wall of the drug guide rod. It effectively solves the problem that when patients undergo heat therapy, it is necessary to inject drugs into the vagina of the patients, and the drug solution injected into the vagina is easy to flow out.

[0013] (2) The present invention provides a 3D printed vaginal hot irrigation aid, which is ergonomically designed and equipped with a sealing block that can fit the patient’s vulva to further prevent leakage of the drug solution injected into the vagina. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] A 3D-printed vaginal thermal irrigation aid includes an integrally formed drug-guided rod 1 and a protective wing 2. The drug-guided rod 1 is cylindrical in shape, and an axial through hole 11 for inserting a urinary catheter is provided in the drug-guided rod 1. The protective wing 2 is provided on the side wall of the drug-guided rod 1.

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

[0024] Example 2

[0025] The rest is the same as in Embodiment 1, except that: a sealing block 3 is integrally formed between the side wall of the proximal end of the drug guide rod 1 and the protective wing 2, the proximal end of the drug guide rod 1 has a concave top end 12, the two opposite sides of the protective wing 2 are arc-shaped, and the edges are integrally formed with baffle strips 21.

[0026] When using: Medical staff push the proximal end of the drug delivery stick 1 into the patient's vagina, and then pass one end of the catheter (not shown in the picture, any common one on the market will do) through the through hole 11. The balloon on the catheter is stuck in the concave top 12. The medication is injected into the vagina through the catheter, which can effectively prevent the medication from flowing out.
