Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a disposable medical intraoperative irrigation fluid diversion device. Background Technology

[0002] In minimally invasive surgical procedures such as urology, orthopedics, and general surgery, continuous and large-volume irrigation with saline or other irrigation solutions is often required to ensure a clear surgical field and remove tissue debris and blood. These procedures typically involve large volumes of irrigation solution with high flow rates, high velocity, and prolonged continuous irrigation. Waste fluid generated during the procedure must be collected and disposed of promptly and effectively.

[0003] Currently, the waste fluid collection devices routinely used in clinical practice are mostly ordinary sterile drapes, simple drainage bags, or open drainage troughs, which have certain shortcomings in practical applications: On the one hand, the fit of traditional drapes or collection devices is not good, and waste fluid is prone to splashing and leakage when flushed with a large amount of water, which not only easily contaminates the operating table and floor environment, but also increases the workload of postoperative cleaning; on the other hand, the existing collection devices are mostly fixed in shape, which makes it difficult to flexibly adjust according to the position of the surgical field, and the fixing method is not stable enough, which makes it easy to shift during the operation, resulting in low waste fluid collection efficiency, and even fluid backflow or overflow.

[0004] Therefore, those skilled in the art have provided disposable medical intraoperative irrigation fluid diversion devices to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a disposable medical intraoperative irrigation fluid diversion device, which solves the problems of poor fit, easy displacement of the existing collection device, and easy leakage during high-flow irrigation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A disposable medical intraoperative irrigation fluid diversion device includes a bag body and an adhesive backing structure. The bag body is generally funnel-shaped, wider at the top and narrower at the bottom, with the upper part being a collection area and the lower part being a constriction diversion area. The inner sidewall of the main body of the bag is also provided with an inner bag, which is attached to the inner wall of the collection area of ​​the main body of the bag. The adhesive backing fixing structure is set at the top edge of the main body of the bag; The lower end of the contraction guide zone is connected to a bottom guide pipe; The inner side of the opening edge of the main body of the bag is also provided with a plastic-coated soft iron wire shaping structure that can be bent and shaped. The upper inner sidewall of the main body of the bag is provided with an anti-overflow backflow hole structure; Through the above technical solutions, the funnel-shaped bag body facilitates liquid convergence and diversion, the adhesive backing structure enables rapid fixation, the plastic-coated soft wire shaping structure ensures the opening fits the surgical field to prevent side leakage, the anti-overflow backflow hole structure buffers the impact of the fluid, and the bottom diversion tube enables efficient collection and sealed discharge of the rinsing fluid.

[0007] Furthermore, the adhesive backing fixing structure includes a low-sensitivity medical pressure-sensitive adhesive layer coated on the top edge of the bag body, and a peelable release paper covering the surface of the low-sensitivity medical pressure-sensitive adhesive layer; Through the above technical solutions, the low-sensitivity medical pressure-sensitive adhesive layer can reduce damage to the skin or drapes while ensuring firm adhesion. The release paper can be peeled off to protect the adhesive layer before use and can be quickly removed during use, simplifying the operation steps.

[0008] Furthermore, the bottom guide tube has a length of 50–60 cm and a width of 8–15 cm, and the inner wall of the bottom guide tube is a smooth surface; The above technical solution ensures that the appropriate tube length and width meet the requirements for rapid flow of high-flow irrigation fluid, and the smooth inner wall reduces fluid flow resistance, preventing tissue debris or blood clots from clogging the flow.

[0009] Furthermore, the diameter of the plastic-coated soft iron wire shaping structure is 1.0–1.5 mm, and it is covered with a medical-grade plastic layer. It is distributed in a ring shape along the entire opening edge of the bag body and is located below the adhesive backing fixing structure. Through the above technical solution, the soft iron wire of appropriate diameter is not only easy to bend and shape manually, but also has sufficient support. The medical-grade plastic coating layer avoids the risk of puncture or metal allergy caused by exposed iron wire, and the ring distribution ensures that the opening can be flexibly adjusted and fitted.

[0010] Furthermore, the anti-overflow backflow hole structure consists of multiple evenly distributed circular through holes with a diameter of 3–5 mm. When the liquid level inside the bag rises to the anti-overflow backflow hole structure, the liquid can flow back into the inner bag through the circular through holes. With the above technical solution, when the liquid level rises sharply due to a sudden large-flow flush, some of the liquid can temporarily flow back and buffer through the circular through-hole, reducing the risk of overflowing out of the bag and improving the stability of the collection process.

[0011] Furthermore, the main body of the bag is made of medical sterile PE film or waterproof non-woven fabric with a thickness of 0.05–0.1 mm, and the inner bag is made of medical grade hydrophilic non-woven fabric or dialysis paper, and is heat-pressed and laminated with the main body of the bag. Through the above technical solutions, the double-layer medical sterile material meets the requirements of hospital infection control, achieves single use to prevent cross-infection, and the appropriate thickness ensures water resistance and leak prevention performance while taking into account the flexibility and low cost of the material.

[0012] Furthermore, the main body of the bag and the bottom guide tube are integrally formed by heat-press sealing connection; Through the above technical solution, the one-piece molding hot-press sealing has no splicing gaps, and the connection can withstand the impact and gravity when a large flow of liquid passes through, avoiding the risk of leakage or detachment at the connection.

[0013] This invention provides a disposable medical intraoperative irrigation fluid diversion device. It has the following beneficial effects: 1.

[0018] 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. Example 1:

[0019] like Figure 1-3 As shown, this embodiment of the invention provides a disposable medical intraoperative irrigation fluid diversion device, including a bag body 1, an adhesive backing structure 2, a bottom diversion tube 3, a plastic-coated soft wire shaping structure 4, and an anti-overflow backflow hole structure 5.

[0020] Specifically, the main body of the bag 1 is made of medical-grade PE film with a thickness of 0.05–0.1 mm. An inner bag 13 is located on its inner wall, made of medical-grade hydrophilic non-woven fabric or dialysis paper, and is heat-pressed and bonded to the main body of the bag 1. The overall shape is funnel-shaped, wider at the top and narrower at the bottom, with a collection area 11 at the top and a shrinkage and drainage area 12 at the bottom. An adhesive backing structure 2 is located at the top edge of the bag and includes a low-sensitivity medical pressure-sensitive adhesive layer 21 and a peelable release paper 22. The bottom drainage tube 3 is 50–60 cm long and 8–15 cm wide, with a smooth inner wall. A plastic-coated soft wire shaping structure 4, 1.0–1.5 mm in diameter, is covered with a medical-grade plastic layer and is installed below the adhesive backing in a ring shape along the opening edge. An anti-overflow / backflow hole structure 5 is located on the side wall of the inner bag 13, consisting of circular through holes with a diameter of 3–5 mm, evenly distributed on the upper inner side of the bag. The main body of the bag 1 and the bottom guide tube 3 are integrally formed and heat-sealed.

[0021] Working principle: Before use, keep the drape or skin below the surgical field dry and clean. Open the sterile packaging, take out the drainage bag, tear off the peelable release paper 22, and attach the low-sensitivity medical pressure-sensitive adhesive layer 21 to the appropriate position below the surgical field. According to the surgical site and the patient's body shape, manually bend the plastic-coated soft wire shaping structure 4 to make the opening shape of the bag body 1 fit the surgical field area and reduce side leakage gaps. During the operation, the irrigation fluid flows into the collection area 11. When the instantaneous flow rate is large and the fluid level rises rapidly, some of the fluid can flow into the inner bag body 13 through the anti-overflow backflow hole structure 5 opened on the inner bag body 13, reducing the risk of fluid directly overflowing from the bag opening. Subsequently, the fluid passes through the inner bag body 13 and collects in the contraction drainage area 12, and is discharged into the external waste fluid collection container through the smooth inner wall bottom drainage tube 3. After the operation, remove the drainage bag as a whole and dispose of it in accordance with medical waste regulations. It is for single use and helps to avoid cross-infection.
