Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a sealing device and a uterine cavity irrigation device. Background Technology

[0002] As a routine gynecological and obstetric instrument, the uterine lavage device is used for irrigation and treatment of inflammatory lesions. It achieves irrigation and drug infusion through vaginal intervention. In a typical application scenario, the uterine lavage device needs to be left in place within the patient's uterine cavity to achieve sustained drug release and infiltration treatment of lesions.

[0003] In the device fixation stage, existing device configurations employ a pressure-expanding fixation structure, specifically including an externally placed expandable balloon and a corresponding drainage system. The balloon is anchored by injecting saline solution into it, and a multi-channel drainage system at the catheter tip provides control. The drainage system components typically utilize a prefabricated, curved external tube structure with integrated control valves. Commonly, when using existing uterine irrigation devices, to improve patient comfort, medical staff will cut and remove the external catheter, and manually close multiple control valves one by one.

[0004] The above-mentioned operating procedure has the following technical characteristics: the control valves are mostly made of hard plastic, and the material properties and sharp edges of the catheter tips may cause patients to experience a foreign body sensation; moreover, the sequential closing of multiple control valves significantly increases the operational complexity for medical staff. Based on this, a sealing device and a corresponding uterine irrigation apparatus are proposed to at least solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sealing device and a uterine cavity irrigation device, which solves the problems of strong patient discomfort and complicated operation for medical staff when the uterine cavity irrigation device is in place and sealed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The present invention proposes a sealing device, which includes a slot, and pressing mechanisms are provided at both ends of the slot.

[0008] The pressing mechanism includes multiple pressing block groups. Each pressing block group has a fixing mechanism at the end away from the pressing direction. The end of the pressing block group away from the fixing mechanism is inserted into the slot. When the pressing block groups are engaged and fixed, the ends of the pressing block groups inserted into the slots abut against each other.

[0009] In a preferred embodiment, the pressing block group has two pressing blocks, which are respectively disposed at both ends of the slot and slidably connected to the slot.

[0010] In a preferred embodiment, the ends of the pressing blocks that abut against each other are provided with mutually adaptable toothed structures.

[0011] Based on the same inventive concept, this embodiment also proposes a uterine cavity irrigation device, including an irrigation device and the aforementioned sealing device. One end of the irrigation device has a slot, and the irrigation device is a flexible tube structure with multiple cavities inside.

[0012] In a preferred embodiment, the slot radially penetrates the irrigator and is perpendicular to the axial direction of the irrigator, and one end of the pressing block assembly inserted into the slot forms an interference fit with the slot.

[0013] In another preferred embodiment, the slot is perpendicular to the axis of the irrigator, and the bottom of the slot is a certain distance from the inner wall of the inner cavity of the irrigator.

[0014] In one embodiment, the apparatus further includes a drainage device, which is a plurality of tubular structures with valves that are independently connected to each cavity within the irrigator.

[0015] In a preferred embodiment, an airbag is fixedly installed on the outer surface of the irrigator, and the interior of the airbag is connected to a portion of the interior cavity of the irrigator.

[0016] In one embodiment, the device further includes a capsule for enclosing the closure.

[0017] In a preferred embodiment, the end of the irrigator away from the closure is provided with a shell structure having multiple circular holes.

[0018] This invention provides a sealing device and a uterine cavity irrigation apparatus. Compared with the prior art, it has the following advantages:

[0019] By using a closure device and the material of the irrigation tube, when placing the irrigation device, the end with the drainage device is cut off. The pressing block can press and seal all the cavities inside the irrigation device at once through the buckle structure. The operation is quick and convenient. In addition, the pressing block is small in size after being locked, and the patient feels less discomfort when wearing it, which increases the patient's willingness to wear the irrigation device for indwelling.

[0029] 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.

[0030] The technical solution in this application is to solve the aforementioned technical problems, and the overall approach is as follows:

[0031] 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 end of the irrigation device with the drainage device is completely cut off. After cutting, a snap-on structure that opens and closes with a press is used to seal the irrigation device with the soft tube material itself. This simplifies the doctor's operation and improves the patient's comfort when wearing it.

[0032] 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.

[0033] Example 1:

[0034] See Figure 1-2As shown, the sealing device proposed in this embodiment includes a slot 11, with pressing mechanisms 12 at both ends of the slot 11. Each pressing mechanism 12 includes multiple pressing block groups 12. Each pressing block group 12 has a fixing mechanism at its end away from the pressing direction, which can engage with other pressing block groups 12. The end of the pressing block group 12 away from the fixing mechanism is inserted into the slot 11. When the pressing block groups 12 are engaged and fixed, the ends of the pressing block groups 12 inserted into the slot 11 abut against each other. It should be noted that the slot 11 is formed on a tubular structure, and the pressing block groups 12 are engaged and fixed by a structure such as a snap-fit ​​mechanism. When the pressing block groups 12 are engaged and fixed, the ends of the pressing block groups 12 away from the fixing mechanism are inserted into the slot 11 and abut against each other, thereby sealing the pipe.

[0035] In a preferred embodiment, each pressing block assembly 12 includes two pressing blocks, which are respectively disposed at both ends of the slot 11 and slidably connected to the slot 11. It should be noted that the two pressing block assemblies 12 can be engaged and fixed with each other by only one pressing, making the operation convenient and quick.

[0036] In a preferred embodiment, the ends of the pressing blocks that abut against each other are provided with mutually adaptable toothed structures. It should be noted that the toothed structures enable the pressing block assembly 12 to be more stable when it abuts against each other, preventing the pressing block assembly 12 from rotating relative to the irrigator axial direction, and further improving the sealing effect on the cavity.

[0037] Example 2:

[0038] See Figure 3 As shown, based on the same inventive concept, this embodiment proposes a uterine irrigation device, including an irrigation device 1 and the aforementioned sealing device. The sealing device is used to seal the tube of the irrigation device 1 near the external end when it is left in place.

[0039] In a preferred embodiment, a slot 11 is provided on the tube body, the slot 11 radially penetrates the irrigation device 1 and is perpendicular to the axial direction of the irrigation device 1, one end of the pressing block inserted into the slot 11 forms an interference fit with the slot 11, and the tube body is a flexible tube with multiple cavities inside. It should be noted that: since the irrigator 1 is a flexible tube structure, when the pressing block assembly 12 is engaged and fixed, the irrigator 1 is deformed under pressure, causing the inner walls of the internal cavity of the irrigator 1 to abut against each other to form a seal, thereby sealing the irrigator 1. Furthermore, the portion of the pressing block assembly 12 located on the outer surface of the irrigator 1 can move with each other as it deforms, thereby reducing the volume of the pressing block assembly 12 and improving the patient's comfort when wearing it. The slot 11 is perpendicular to the axis of the irrigator 1. When medical staff seal the irrigator 1 through the sealing device, they only need to press the pressing block assembly 12 perpendicularly to the irrigator 1, resulting in the shortest pressing stroke and simple operation. The interference fit formed between the pressing block assembly 12 and the slot 11 can improve the sealing performance between the pressing block assembly 12 and the slot 11.

[0040] In another preferred embodiment, the slot 11 is perpendicular to the axial direction of the irrigator 1 but does not penetrate the irrigator 1, and the tube body is a flexible tube with multiple cavities inside. It should be noted that: the slot 11 is perpendicular to the axial direction of the irrigator 1, resulting in the shortest pressing stroke and simple operation; the slot 11 does not penetrate the irrigator 1 at this time, and when the pressing block assembly 12 is engaged and fixed by the snap-fit ​​structure, the ends of the pressing block assembly 12 inserted into the slot 11 abut against and press against the inner wall of the irrigator 1's tube, causing it to deform and stick together to seal it, and at this time, the part of the pressing block assembly 12 inserted into the slot 11 can be further shortened, so that the pressing mechanism has a smaller volume, further improving the comfort of the patient when wearing it.

[0041] Example 3:

[0042] See Figure 3 As shown, this embodiment proposes a uterine cavity irrigation device, including the aforementioned irrigation device 1 and a sealing device. The device also includes a drainage device. The drainage device is connected to one end of the irrigation device 1 near the sealing device. The drainage device consists of multiple tubular structures with valves, each independently connected to a cavity within the irrigation device 1. It should be noted that medical personnel can use the drainage device and other tools, such as syringes, to perform irrigation or inject medication into the patient's uterine cavity, and the valves seal the drainage device and the connecting tubes within the irrigation device 1.

[0043] In a preferred embodiment, the irrigation device further includes an air bladder 2 fixedly mounted on the outer surface of the tube of the irrigation device 1, the interior of the air bladder 2 communicating with a portion of the internal cavity of the irrigation device 1. It should be noted that medical personnel can inject media such as saline solution or air into the air bladder 2 of the irrigation device using a drainage device or other tools such as a syringe, causing the air bladder 2 to inflate and form an interference fit with the patient's uterine cavity or vagina for fixation.

[0044] Example 4:

[0045] See Figure 4 As shown, this embodiment proposes a uterine irrigation device, including the aforementioned irrigation device 1 and a sealing device. The device also includes a capsule 3, which is used to enclose the sealing device. The capsule is elongated and spindle-shaped with a smooth surface. It should be noted that during placement, after medical personnel seal the irrigation device 1 with the sealing device, they use the capsule 3 to enclose the sealing device and fix it to one end of the irrigation device 1 using methods such as tying. This prevents the patient from experiencing a foreign body sensation due to the material properties and sharp edges of the tube end of the irrigation device 1 outside the patient's body, thus improving the patient's comfort when wearing the irrigation device.

[0046] See Figure 5As shown, in a preferred embodiment, the end of the irrigation device 1 furthest from the sealing device has a shell structure with multiple circular holes. It should be noted that when medical personnel use the irrigation device 1 to irrigate or inject medication into the patient's uterine cavity, the liquid is sprayed into the uterine cavity in all directions through the circular holes, which improves the efficiency of irrigation and medication contact.

[0047] In summary, compared with existing technologies, it has the following beneficial effects:

[0048] 1. The tube body is sealed by the slotted design, the pressing block assembly, and the toothed structure at one end of the pressing block assembly that abuts against each other; the abutting pressing block assembly and the toothed structure further enhance the sealing effect on the tube body.

[0049] 2. By designing a closure, a portion of the pressing block assembly is inserted into the slot during indwelling irrigation, allowing it to shift with the deformation of the tubing, thus reducing the volume occupied by the closure. Furthermore, during indwelling irrigation, medical staff can completely cut off the end of the irrigation device with the drainage device, and then use the pressing block assembly with its snap-fit ​​structure to seal all the cavities inside the irrigation device in one go. This operation is quick and convenient, simplifies the doctor's work, and improves the patient's comfort when wearing the device.

[0050] 3. The capsule design, with its elongated spindle shape and smooth surface, avoids the discomfort caused by the closure device remaining in the patient's vagina, further improving the patient's comfort when wearing the irrigation device.

[0051] 4. The shell design allows medical staff to quickly perform irrigation and medication injection, improving their work efficiency.
