Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an obstetric irrigation device. Background Technology

[0002] In obstetric and gynecological clinical nursing, irrigation is a common and crucial nursing measure, especially before and after delivery, during gynecological examinations, and postoperative care. Irrigation devices are often needed to clean and disinfect relevant areas to reduce infection risk, promote recovery, and improve the quality of care. Traditional obstetric irrigators typically use manual infusion or simple squeezing devices to push disinfectant to the area to be irrigated. However, existing irrigation devices still have many shortcomings in terms of structural design and ease of operation, making it difficult to meet the clinical needs for efficient, safe, and portable irrigation.

[0003] Existing rinsing equipment generally suffers from the following problems during use: First, some devices have cumbersome structures, requiring multiple assembly steps before use, making the operation process complicated and affecting efficiency; Second, the rinsing direction cannot be flexibly adjusted, and the nozzle angle is fixed, making it difficult to accurately aim the liquid spray at the target area, affecting the cleaning effect; Third, the liquid delivery of some devices relies on traditional hand-operated bulb pumps or external syringes, which are structurally unstable and prone to backflow or poor spraying; Fourth, the nozzles or connecting structures are often difficult to store effectively after rinsing, occupying a lot of space and making them inconvenient for subsequent storage and transport. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an obstetric irrigator that is compact in structure, easy to operate, has flexible spraying function, and is easy to store, thereby improving the efficiency and safety of clinical nursing work.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An obstetric douche includes a reservoir, the reservoir comprising a body for storing a douche solution, and a pressing part connected to the tail end of the body;

[0007] Pressing the pressing part allows the solution stored inside the tank to be squeezed out from the opening of the tank;

[0008] The open end of the tank is connected to a connecting pipe, and the other end of the connecting pipe is connected to an extension.

[0009] One end of the extension is rotatably connected to a directional arm;

[0010] One end of the extension has a through-hole;

[0011] One end of the directional arm is fixedly connected to a positioning head, and the other end of the directional arm is connected to a nozzle. An input hole is provided on the positioning head.

[0012] Furthermore, the pressing part is shaped like an elastic corrugated tube, and a buckle is fixedly connected to the outer side of one end of the pressing part. Anti-slip protrusions are evenly distributed on the side of the buckle.

[0013] Furthermore, a retaining ring is fixedly connected to the inner side of the connecting pipe.

[0014] Furthermore, the extension member has a receiving groove on its outer side, which can accommodate the folded directional arm.

[0015] Furthermore, one end of the extension is provided with a pin connector, the positioning head is connected inside the pin connector, and positioning pins are provided on both sides of the positioning head.

[0016] Furthermore, the outer side of the opening end of the tank is provided with a first connecting thread, the inner ends of the connecting pipe are respectively provided with a second connecting thread and a third connecting thread, and the outer side of one end of the extension is provided with a fourth connecting thread.

[0017] Furthermore, anti-slip strips are provided at equal intervals around the central axis on the outer side of the connecting pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention effectively solves the problems of complex liquid propulsion structure and cumbersome operation of existing flushers by setting a corrugated tubular pressing part that can be elastically pressed in the liquid storage tank. The pressing part can increase the pressure inside the tank by pressing with the palm, and push the disinfectant out through the liquid channel, realizing the continuous flushing function without external syringes or manual filling devices, simplifying the operation process and improving the efficiency and stability of use.

[0020] This invention features a wristband and anti-slip protrusions on the outer side of the pressing part, allowing the operator to hold the device stably even when their hands are wet or they are wearing gloves, preventing slippage. The elastic rebound design of the corrugated tube structure enables automatic reset after pressing, thus supporting continuous pressing operations and meeting the clinical needs for continuous flushing in obstetric nursing.

[0021] This utility model, by setting a multi-stage threaded connection structure between the connecting pipe and the extension, enables the rinsing device to have good modularity and sealing performance, preventing liquid leakage or loosening of the connection during rinsing; the anti-slip strip set on the connecting pipe also enhances the grip stability during assembly and operation, improving the reliability of the overall connection and the safety of operation.

[0022] This invention features a receiving groove on the outside of the extension member, which houses the rotatable reversing arm structure. The arm unfolds by rotation before use and folds away afterward, significantly reducing the overall size of the device and solving the problems of existing equipment being difficult to carry and store. Simultaneously, the design of the pin joint and positioning column structure ensures that the reversing arm remains stably fixed at a predetermined angle after rotation, allowing for flexible adjustment of the nozzle's spray direction and improving the accuracy of the cleaning liquid spray. This solves the problem of existing devices having a fixed rinsing angle and difficulty in aligning with the target area.

[0023] This invention features a positioning head at one end of the directional arm with an input hole, allowing liquid from the storage tank to enter the directional arm and be sprayed out from the nozzle after passing through the connecting pipe and extension channel. This structure ensures smooth liquid flow and stable spraying, thereby improving the actual flushing effect and meeting the comprehensive requirements for safety, controllability, and precision in obstetric and gynecological clinical flushing operations.

[0037] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0038] Example 1:

[0039] See Figure 1-8 An obstetric rinsing device includes a storage tank 1, which includes a tank body 11 for storing rinsing fluid, and a pressing part 12 is connected to the tail end of the tank body 11.

[0040] The pressing part 12 achieves a rebound function through an elastic structure, providing continuous and controllable pressure output; the tank 11 is used to hold disinfectant or rinsing solution, and its material is preferably medical-grade polyethylene with a certain degree of elasticity to facilitate pressing control; the setting of the pressing part 12 forms a closed cavity inside the tank 11, and internal pressure can be generated by squeezing, which delivers the cleaning solution outward from the opening of the tank 11 along the liquid channel, meeting the actual needs of rinsing force and continuity in obstetrics and gynecology nursing; the volume of the tank 11 is designed according to the conventional clinical dosage, which is convenient for medical staff to operate with one hand, improving cleaning efficiency and accuracy.

[0041] See Figure 1-2 The pressing part 12 is shaped like an elastic corrugated tube, and a buckle 121 is fixedly connected to the outer side of one end of the pressing part 12. Anti-slip protrusions 1211 are evenly distributed on the side of the buckle 121.

[0042] The corrugated structure gives the pressing part 12 good resilience during operation, allowing it to quickly return to its original position after release, facilitating multiple continuous rinsing sessions. The wristband 121 has a ring structure, making it easy for the operator to insert their fingers for stable grip and precise control. The anti-slip protrusions 1211 are made of a high-friction coefficient material, and their dense arrangement increases the friction during gripping, preventing slippage due to wet hands or wearing gloves, thus improving the overall stability of the machine and adapting it to high-frequency clinical operation scenarios.

[0043] See Figure 3A retaining ring 22 is fixedly connected to the inner side of the connecting pipe 2;

[0044] The retaining ring 22 is located in the middle of the connecting pipe 2 to prevent the connecting port from dislodging due to excessive rotational force during the connection process, and to ensure the connection stability between the connecting pipe 2 and the tank 11 and the extension 3. The distance between the retaining ring 22 and the second connecting thread 23 is precisely calculated to form an effective anti-backflow and limiting function, which improves the sealing and reliability of the overall liquid delivery path and avoids liquid backflow or leakage during clinical flushing.

[0045] See Figure 4-8 The extension 3 has a receiving groove 31 on its outer side, which can accommodate the folded deflector arm 4.

[0046] The receiving groove 31 has a longitudinal groove structure, the depth and width of which are adapted to the folded thickness of the deflector arm 4, so that the deflector arm 4 can be tightly stored in the groove when not in use, reducing the space occupied by the equipment; the bottom of the receiving groove 31 is provided with an embedded locking position to prevent the deflector arm 4 from coming loose during transportation or storage; this structural design effectively solves the problem of traditional flushing devices being bulky and inconvenient to carry, and improves the portability and storage convenience of the equipment.

[0047] See Figure 4-8 One end of the extension 3 is provided with a pin connector 32, and the positioning head 41 is connected in the pin connector 32. Positioning pins 412 are provided on both sides of the positioning head 41.

[0048] The pin connector 32 is used to enable the rotatable installation of the positioning head 41, which facilitates the adjustment of the spray direction according to the target flushing area during use. The positioning head 41 is inserted into the corresponding holes and slots on both sides of the pin connector 32 through the positioning pin 412, forming an axial limiting structure to prevent the directional arm 4 from shifting during liquid flow. This design, combined with the defect of "the nozzle direction of the existing device is not adjustable" mentioned in the background technology, significantly improves the controllability of the nozzle direction and the accuracy of liquid spraying, ensuring that the flushing effect is controllable and safe.

[0049] See Figure 1-6 The outer side of the opening end of the tank body 11 is provided with a first connecting thread 111, the inner ends of the connecting pipe 2 are respectively provided with a second connecting thread 23 and a third connecting thread 24, and the outer side of one end of the extension 3 is provided with a fourth connecting thread 33.

[0050] The four sets of threaded structures enable modular disassembly and assembly of the liquid storage tank 1, connecting pipe 2, and extension 3, facilitating cleaning, replacement, and maintenance. The connecting thread design adopts standard medical pitch, ensuring both the stability of the screw-on fastening and the ease of quick disassembly and assembly, thus improving clinical efficiency. The multi-stage connection structure design forms a closed liquid path in the flushing device, preventing flushing fluid leakage and enhancing the overall compatibility of the device, meeting the needs of multiple application scenarios.

[0051] See Figure 3 Anti-slip strips 21 are provided at equal intervals around the central axis on the outer side of the connecting pipe 2;

[0052] The anti-slip strips 21 are arranged in a ring and are made of soft polymer rubber material. By increasing the contact area, they enhance the friction between the operator's palm and the tube. The design of the anti-slip strips 21 takes into account the actual situation in clinical operation where it is necessary to frequently hold and connect various parts. It effectively avoids slipping errors caused by factors such as hand sweat and liquid residue, and enhances the stability of operation and the safety of the whole machine.

[0053] Example 2: Storage tank structure design with corrugated pressing part

[0054] See Figure 1-2 and Figure 6 This embodiment provides an obstetric rinsing device with a corrugated tubular elastic pressing part, including a medical polyethylene tank of model MF-400. One end of the tank is provided with an integrally injection-molded pressing part, which is a flexible corrugated structure with a thickness of 2mm and a wave pitch of 5mm. During the pressing operation, after the operator applies force to the pressing part with his palm, the internal pressure of the tank rises rapidly, pushing the disinfectant along the channel to the nozzle to complete the rinsing process. After releasing, the pressing part automatically rebounds due to the elasticity of the material, forming a stable periodic pressurization process to achieve continuous rinsing function.

[0055] In the comparative case, a common non-elastic liquid storage bag was used in conjunction with an external syringe for liquid delivery. This method requires both hands to operate, and the external structure is not secure and prone to leakage. The rinsing process is also characterized by frequent operation, low efficiency, and uneven cleaning. In contrast, this embodiment features an integrated structure, is controllable with one hand, and has stable rebound, which improves the ease of operation and the continuity of rinsing.

[0056] Example 3: Press control design with anti-slip operation structure

[0057] See Figure 2 This embodiment provides a flushing control structure with an anti-slip design. The end of the pressing part is equipped with a ring-shaped buckle with an inner diameter of 25mm. The buckle is made of medical-grade flexible TPR material, and its surface is densely covered with hemispherical anti-slip protrusions with a diameter of 1mm and a height of 0.5mm. The protrusions are model NF-TPR121, and the protrusion density is 100 pieces / cm². The operator can insert the index and middle fingers into the buckle to form a stable fulcrum, and at the same time use the palm to press the corrugated tube to form a single-hand operation circuit.

[0058] In the comparative case, the structure without a wristband or anti-slip protrusions is prone to slipping due to wet gloves, requiring repeated adjustments of hand gestures and causing operational interruptions. This embodiment improves operational stability and is particularly suitable for obstetric and gynecological care scenarios that require long-term continuous rinsing.

[0059] Example 4: Achieving a stable connection using multi-stage threads and an anti-slip structure.

[0060] See Figure 1 , Figure 3 and Figure 6 This embodiment adopts a four-section precision threaded connection structure: the opening end of the tank is provided with a first connecting thread M18×1.5; the two ends of the connecting pipe are respectively provided with a second connecting thread M18×1.5 and a third connecting thread M16×1.5; the extension is provided with a fourth connecting thread M16×1.5; the thread adopts a self-locking structure and is equipped with a silicone sealing ring to enhance the liquid sealing performance; at the same time, the outside of the connecting pipe is provided with a 1mm thick and 3mm high anti-slip strip, model HS-PU21, which is spirally distributed to prevent slippage during operation.

[0061] The comparative cases used straight-insertion or single-threaded connections, which are prone to loosening or leakage at the interface during rinsing, and the connection operation is inconvenient; this embodiment achieves high-strength connection and excellent sealing performance through the synergy of precision threads and anti-slip structure, which significantly improves the stability and reliability of the rinsing device connection system.

[0062] Example 5: Foldable and retractable directional arm structure design

[0063] See Figure 4-8 In this embodiment, an extension component with a receiving groove is used. The extension component is an ABS one-piece injection molded structure, model HX-03. One end of the extension component is provided with a concave receiving groove with a length of 60mm, a width of 12mm, and a depth of 10mm. The receiving groove is provided with a magnetic positioning groove, which can automatically attract and lock with the folded directional arm. The directional arm is connected to the positioning head through a pin joint. The positioning head is provided with Φ3mm positioning posts on both sides to fix the angle after rotation and unfolding, ensuring that the nozzle direction is aligned with the required part.

[0064] In contrast, the case lacks a storage slot, and the directional arm is exposed for extended periods, increasing storage volume and making components prone to deformation. Furthermore, the traditional structure has a fixed nozzle angle, making it impossible to flexibly adjust the rinsing direction. This embodiment achieves structural folding and storage while improving ease of use and spray accuracy, reducing space occupation, and enhancing target adaptability.

[0065] Example 6: Optimization of Nozzle Input Conduction and Directional Spray Structure

[0066] See Figure 1 , Figure 4 and Figure 6This embodiment adopts an integrated directional arm structure with an internal Φ2mm liquid passage that seamlessly connects with the input port. The positioning head is made of polycarbonate and has a 1.5mm diameter input port, which ensures stable introduction of disinfectant through precise fit. The nozzle has a conical multi-hole design with a 0.4mm diameter orifice and a 45° angled spray pattern, providing a spray coverage diameter of up to 80mm. The overall structure forms a continuous and stable spray system, adaptable to the rinsing needs of different body positions.

[0067] The comparative case used a straight-through nozzle structure and lacked directional adjustment design, resulting in a fixed spray direction that could easily cause blind spots or secondary contamination during rinsing. This embodiment, through an adjustable directional structure and a stable input path design, ensures controllable liquid output direction and uniform atomization, significantly improving the clinical rinsing effect.

[0068] The working principle of this utility model is as follows:

[0069] When in use, pour the disinfectant into the tank 11 from the open end of the tank 11, then screw the connecting pipe 2 into the tank 11, and rotate the deflector arm 4 out of the receiving groove 31. When the deflector arm 4 cannot be rotated, the inlet hole 411 will be aligned with the channel 34. Then, aim the nozzle 42 at the area to be rinsed, and hold the handle ring 121 with your fingers while pressing the pressing part 12 with your palm. When the pressing part 12 is pressed, the pressure in the tank 11 will increase. As the pressure increases, the disinfectant in the tank 11 will pass through the channel 34 and enter the deflector arm 4 through the inlet hole 411, and finally be sprayed out from the nozzle 42 to clean the area to be rinsed.

[0070] When you release your hand from pressing the pressing part 12, the pressing part 12 is elastic and will automatically return to its original position under the action of the elastic force; then you can press the pressing part 12 again to achieve continuous rinsing operation.

[0071] After rinsing is complete, the deflector arm 4 is stored in the receiving slot 31, and the connecting pipe 2 is unscrewed from the tank 11. Then, the deflector arm 4 is inserted into the tank 11, which reduces the overall space occupied.

[0072] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
