Description

Technical Field

[0001] This utility model belongs to the medical field, specifically relating to a breast sinus drainage and drug infusion device. Background Technology

[0002] Breast sinus tracts typically form after abscesses develop within the breast due to conditions such as mastitis or breast cancer, and then rupture. Patients usually experience symptoms such as breast swelling and pain; in severe cases, pus discharge and ulceration may occur. Breast sinus tracts can be surgically repaired by incising the skin and sinus wall to create a direct channel to the outside, facilitating pus drainage. This method is suitable for patients with complicated mastitis and sinus tract formation. However, existing breast sinus tract drainage devices require separate equipment for drainage and medication administration, resulting in low efficiency and potential patient discomfort. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a breast sinus tract drainage and drug injection device.

[0004] This utility model discloses a mammary sinus drainage and drug injection device, which includes a main body of the drainage and drug injection device, a drainage channel and a drug injection channel;

[0005] The main body of the drainage and injection device is a hollow structure with an upper cone and a lower cylinder. The hollow inner wall has a drainage channel opened from top to bottom along the circumference. The injection channel is formed by the hollow structure inside the main body of the drainage and injection device.

[0006] This utility model has the following beneficial effects:

[0007] This invention combines drainage and medication injection into one device, enabling simultaneous operation of both. This invention significantly simplifies the operation process, reduces costs, and alleviates patient discomfort, making it a promising device for market application. Attached Figure Description

[0008] Figure 1 This is a cross-sectional view of a mammary sinus drainage and drug infusion device according to the present invention;

[0009] Figure 2 This is a top sectional view of a mammary sinus drainage and drug infusion device according to the present invention;

[0010] The device includes a main body 1 for drainage and drug injection, a drainage channel 2, a drug injection channel 3, a circular channel 21, and an elastic compression tablet 22. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the spirit of the contents disclosed in the present invention will be described in detail below. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0012] The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0013] Specific implementation method one: Combining Figures 1 to 2 This embodiment describes a mammary sinus drainage and drug injection device, which includes a main body 1, a drainage channel 2, and a drug injection channel 3.

[0014] The main body 1 of the drainage and injection device is a hollow structure with an upper cone and a lower cylinder. The hollow inner wall has a drainage channel 2 opened from top to bottom along the circumference. The injection channel 3 is formed by the hollow structure inside the main body 1 of the drainage and injection device.

[0015] Method of using the mammary sinus drainage and drug infusion device of this embodiment:

[0016] In use, the mammary sinus drainage and infusion device is introduced into the mammary sinus. Infusion channel 3 is connected to the infusion device, and drainage channel 2 is connected to the collection tank. After drainage is completed, the medication is injected through infusion channel 3. Before medication injection, the elastic pressure plate 22 compresses the infusion channel 3 to prevent pus from flowing in. During medication injection, the elastic pressure plate 22 is pushed open by the medication, and the medication is injected into the lesion through the head of the infusion channel 3.

[0017] Specific Implementation Method Two: Combining Figures 1 to 2 This embodiment differs from the first embodiment in that the drainage channel 2 is formed by multiple circular channels 21 arranged circumferentially.

[0018] Everything else is the same as in Specific Implementation Method 1.

[0019] Specific implementation method three: Combining Figures 1 to 2 This embodiment differs from specific embodiment one in that: an elastic pressure plate 22 is provided between two adjacent circular channels 21; the bottom of the elastic pressure plate 22 is connected to the inner wall of the drainage channel 2, and the top is in contact with the outer wall of the injection channel 3. The injection channel 3 is made of silicone.

[0020] Everything else is the same as in Specific Implementation Method 1.

[0021] Specific implementation method four: Combination Figures 1 to 2This embodiment differs from specific embodiment one in that the injection channel 3 is made of silicone.

[0022] Everything else is the same as in Specific Implementation Method 1.

[0023] Specific Implementation Method Five: Combining Figures 1 to 2 This embodiment differs from Specific Embodiment 1 in that the top of the injection channel 3 is higher than the height of the drainage channel 2.

[0024] Everything else is the same as in Specific Implementation Method 1.

[0025] Specific Implementation Method Six: Combination Figures 1 to 2 This embodiment differs from Specific Embodiment 1 in that the injection channel 3 is connected to the injection port of the injection device.

[0026] Everything else is the same as in Specific Implementation Method 1.
