Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a uterine irrigation device. Background Technology
[0002] A uterine irrigation device is a common medical instrument used in the treatment of intrauterine inflammation and intrauterine surgery. It is used to inject medication into the uterine cavity through an irrigation device placed in the vagina for irrigation or treatment. In order to improve the treatment effect of intrauterine inflammation and other diseases, the uterine irrigation device is often left in one end of the patient's uterine cavity for a period of time and then closed so that the medication can remain in the patient's uterine cavity.
[0003] In existing technologies, uterine irrigation devices are fixed to the outer surface of the device via an air balloon and a drainage device connected to the air balloon. The air balloon expands with water injection and fits tightly against the patient's uterine cavity and vagina. To facilitate the injection of liquid and medication into the air balloon and uterine cavity by the doctor, the drainage device is often a long tube structure with a valve that bends outward. This makes it relatively large, causing discomfort during indwelling and affecting the patient's mobility, thus impacting the success rate of indwelling. In addition, there are cases where the external part is directly cut off during indwelling, leaving only the internal part. This operation causes irreversible structural damage to the uterine irrigation device, making it unusable and resulting in a low reusability rate. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a uterine cavity irrigation device, which solves the problems of strong discomfort and low reusability of existing uterine cavity irrigation devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] This utility model proposes a uterine cavity irrigation device, which includes an irrigation device body, the irrigation device body including a long tube, a short tube, and a connecting mechanism for connecting the long tube and the short tube.
[0007] The connecting mechanism includes a recessed structure at one end of the long tube, a protrusion at one end of the short tube, and a first airbag fixedly installed on the outside of the protrusion.
[0008] In a preferred embodiment, both the long tube and the short tube are flexible tube structures with multiple cavities inside, and the opening positions of the cavities are adapted to each other. A second airbag is fixedly installed on the outer surface of the long tube, and the interior of the second airbag is connected to a cavity inside the long tube. A Robert clip is fixedly installed on the outer surface of the end of the long tube near the recessed structure, and a cavity is also opened inside the short tube to connect to the first airbag.
[0009] In a preferred embodiment, the protrusion and the outer surface of the first airbag are coated with a hydrogel coating.

[0011] In one embodiment, valves are fixedly installed at the end of the inner cavity of the long tube near the recessed structure, and cannulas are fixedly installed at the outer side of the inner cavity of the short tube near the protrusion, with the valves and cannulas being matched in position.
[0012] In a preferred embodiment, the cavity at the end of the short tube away from the protrusion is connected to a drainage device, which is a plurality of tubular structures with valves that are independently connected to each cavity inside the short tube.
[0013] In a preferred embodiment, there are two second airbags, which are respectively disposed on the outer surface of the ends near both ends of the long tube.
[0014] In a preferred embodiment, the outer surfaces of the first airbag and the second airbag are provided with water-soluble adhesive strips with color markings.
[0015] In one embodiment, the device further includes a negative pressure ball, which is disposed at the end of the short tube away from the connecting mechanism. The negative pressure ball is connected to the cavity inside the short tube and is made of transparent silicone.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] The technical solution in this application is to solve the aforementioned technical problems, and the overall approach is as follows:
[0032] To address the discomfort caused by the drainage device without affecting the irrigation of the patient's uterine cavity or the fixation of the irrigation device, the drainage device is designed to be detachable. It can be removed during indwelling, thus avoiding irreversible damage to the device caused by directly cutting off the external part. After the drainage device is removed, the indwelling irrigation device can be sealed, which can improve the patient's comfort when wearing it.
[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0034] See Figure 1As shown, this embodiment proposes a uterine irrigation device, including an irrigation device body. The irrigation device body includes a long tube 1, a short tube 2, and a connecting mechanism for connecting the long tube 1 and the short tube 2. The connecting mechanism includes a recessed structure 11 at one end of the long tube 1, a protrusion 21 at one end of the short tube 2, and a first airbag 22 fixedly installed on the outside of the protrusion 21. It should be noted that when connecting the long tube 1 and the short tube 2, the protrusion 21 is inserted into the recessed structure 11, and a medium such as saline or air that can inflate the first airbag 22 is injected into it. The first airbag 22 inflates, so that the protrusion 21 and the first airbag 22 form an interference fit with the recessed structure 11, thereby fixing the short tube 2 at one end of the long tube 1. When the irrigation device is in place, the first airbag 22 can be disassembled by draining water using a structure such as a syringe.
[0035] See Figure 2 As shown, in a preferred embodiment, both the long tube 1 and the short tube 2 are flexible tube structures with multiple cavities inside, and the opening positions of the cavities are adapted to each other. The second airbag 12 is fixedly installed on the outer surface of the long tube 1, and the interior of the second airbag 12 is connected to a cavity inside the long tube 1. The Robert clip 13 is fixedly installed on the outer surface of the end of the long tube 1 near the recessed structure 11. The short tube 2 also has a cavity inside that connects to the first airbag 22. It should be noted that: a cavity inside the short tube 2 allows for the injection of media such as saline or air into the first balloon 22; a cavity inside the long tube 1 allows for the injection of media such as saline or air into the second balloon 12, causing the second balloon 12 to inflate and form an interference fit with the patient's uterine cavity or vagina, thereby fixing the irrigation device; when the long tube 1 is connected to the short tube 2, water can be injected into the patient's uterine cavity for irrigation or medication through a cavity connected to the short tube 2 and the long tube 1, and other cavities connected to the short tube 2 and the long tube 1 can inject media such as saline or air into the second balloon 12; when the long tube 1 and the short tube 2 are disassembled by the connecting device, one end of the long tube 1 is sealed by the Robert clamp 13 to prevent leakage when the irrigation device is left in place.
[0036] In a preferred embodiment, the outer surfaces of the protrusion 21 and the first airbag 22 are coated with a hydrogel coating. It should be noted that the hydrogel coating can provide good airtightness when the protrusion 21 and the first airbag 22 are inserted into the recessed structure 11 and the first airbag 22 expands and fits the recessed structure 11 with an interference fit, thus preventing leakage during irrigation of the patient's uterine cavity, injection of medication into the uterine cavity, injection of media such as saline or air into the second airbag 12, and afterwards.
[0037] In a preferred embodiment, both the long tube 1 and the short tube 2 have continuous graduation markings on their outer surfaces. It should be noted that the continuous graduation markings allow medical personnel to determine the insertion depth of the irrigation device.
[0038] Example 2:
[0039] See Figure 3-4 As shown in this embodiment, a uterine cavity irrigation device includes the aforementioned irrigation device body and a connecting mechanism. A valve 14 is fixedly installed at one end of the inner cavity of the long tube 1 near the recessed structure 11, and an insertion tube 23 is fixedly installed on the outer side of the inner cavity of the short tube 2 near the protrusion 21. The valve 14 and the insertion tube 23 are positioned to match each other. It should be noted that the valve 14 is made of rubber and has a central slit. Normally, it is sealed. When connecting the long tube 1 and the short tube 2, the insertion tube 23 on the short tube 2 is inserted into the cavity on one side of the long tube 1. The insertion tube 23 can then push open the valve 14 to form an interference fit, further strengthening the connection between the long tube 1 and the short tube 2, and opening the valve 14 to connect the cavities on both sides. Multiple insertion tubes 23 cooperate with the inner cavity of the long tube 1 for positioning, preventing axial rotation of the short tube 2 and the long tube 1 during patient irrigation or drug injection, which could lead to misalignment of the cavity openings and require disassembly and reassembly.
[0040] See Figure 4 As shown, in a preferred embodiment, the end of the short tube 2 away from the protrusion 21 is connected to a drainage device. The drainage device consists of multiple tubular structures with valves, each independently connected to a cavity within the short tube 2. It should be noted that medical personnel can use the drainage device, such as syringes, or other tools, to inject media like saline or air into the lavage bulb of the irrigation device, or to perform irrigation or medication injection into the patient's uterine cavity. The cavity connected to the first balloon 22 is sealed by the valves, maintaining the connection between the long tube 1 and the short tube 2.
[0041] In a preferred embodiment, there are two second airbags 12, respectively disposed on the outer surface of the ends near both ends of the long tube 1. It should be noted that the two second airbags 12 expand by injecting water, forming an interference fit with the patient's uterine cavity or vagina for fixation, which provides a better fixation effect than a single airbag.
[0042] See Figure 5 As shown, in a preferred embodiment, the outer surfaces of the first airbag 22 and the second airbag 12 are provided with water-soluble adhesive strips 3 marked with colors. It should be noted that the water-soluble adhesive strips 3 will gradually fade after repeated use, reminding medical staff to replace the irrigation device.
[0043] Example 3:
[0044] See Figure 6As shown in the figure, this embodiment proposes a uterine cavity irrigation device, including the aforementioned irrigation device body and a connecting mechanism. The device also includes a negative pressure ball 4, which is located at the end of the short tube 2 furthest from the connecting mechanism. The negative pressure ball 4 communicates with the cavity inside the short tube 2 and is made of transparent silicone. It should be noted that after the irrigation device is in place, medical personnel reconnect the short tube 2 via the connecting mechanism. The end of the short tube 2 furthest from the connecting mechanism is connected to the negative pressure ball 4. By pressing the negative pressure ball 4, the medication and other fluids remaining in the patient's uterine cavity can be quickly aspirated. The transparent silicone negative pressure ball 4 allows doctors to easily check whether the aspirated fluid contains blood or pus, facilitating further treatment.
[0045] See also Figure 7 As shown, in one embodiment, the above-mentioned uterine irrigation device also includes a long spindle-shaped capsule 5, which is used to wrap the Robert clip 13. It should be noted that when the device is placed, after the medical staff seals a section of the long tube 1 with the Robert clip 13, they use the capsule 5 to wrap the Robert clip 13 and fix it to one end of the long tube 1 by means of tying or other methods, thereby improving the patient's comfort when wearing the irrigation device.
[0046] In summary, compared with existing technologies, it has the following beneficial effects:
[0047] 1. The long tube, short tube, and the connecting mechanism formed by the concave structure, protrusion, and first air bladder make the long tube and short tube detachable. This avoids the discomfort caused by the short tube and the drainage mechanism connected to the short tube remaining in the patient's vagina when the irrigation device is left in place, which increases the patient's willingness to use the device, thereby increasing the reusability of the device and reducing the consumption of medical equipment.
[0048] 2. Through the design of the hydrogel coating, cannula, and valve structure, good airtightness and stability are maintained when the long and short tubes are connected.
[0049] 3. Through the setting of scale markings, water-soluble adhesive strips, and negative pressure bulbs, medical staff can quickly become familiar with the specific usage status of this device and the recovery status of patients after irrigation treatment, thereby improving the work efficiency of medical staff.
[0050] 4. The capsule design avoids the discomfort caused by the Robert clip 13 remaining in the patient's vagina, improving the patient's comfort when wearing the irrigation device.
