Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a sterile surgical membrane with blood collection function. Background Technology

[0002] Sterile surgical membranes are medical materials made by coating a medical pressure-sensitive adhesive onto a film such as polyurethane or polyethylene as a base. They are applied to the surgical site during surgery to prevent skin flakes that may carry bacteria from spreading to the surgical wound and to prevent microorganisms from the deeper layers of the skin around the surgical incision from migrating to the skin surface and spreading to the surgical incision, thereby preventing surgical site infection.

[0003] An existing sterile surgical membrane with the authorized publication number CN221808054U has a design where a pressure-sensitive adhesive ring is placed along the edge of the surgical opening on the side of the surgical membrane that contacts the human body. When the sterile surgical membrane is placed on the patient, the edge of the surgical opening is tightly bonded to the human body. A support strip is also provided on the side of the collection bag away from the surgical membrane and at the edge of the collection chamber opening. The support strip is a deformable plastic strip that is arranged along the length of the edge of the collection chamber opening. By shaping the support strip, it can open the opening of the collection bag, making the collection bag less likely to close automatically during the operation and ensuring that it can always collect waste liquid.

[0004] However, existing pressure-sensitive adhesives involve placing the surgical membrane itself in contact with the body, precisely applying the adhesive along the side edges of the surgical opening. But when using pressure-sensitive adhesives on gynecological surgical membranes in areas with many skin folds or complex patient positions, the membrane cannot be completely adhered to the surgical drape. This small adhesion area increases the risk of membrane displacement, potentially leading to waste fluid leakage during surgery and increasing the probability of contamination of the surgeon's gown. The support strips, made of deformable plastic, can open the collection bag, but may deform due to accidental impact or pressure during surgery, causing the collection bag to close and affecting waste fluid collection. This can further damage the surgical membrane, increasing the rate of contamination of the surgeon's gown and postoperative infection, while also increasing the occupational exposure risk for medical personnel. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a sterile surgical membrane with blood collection function. Through the collection area and collection zone formed by the aluminum core wire, it can effectively collect the blood and waste fluid generated during the operation, avoid blood flowing around on the operating table, and reduce the chance of blood coming into contact with the surgical incision by timely collection and discharge of blood and waste fluid generated during the operation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sterile surgical membrane with blood collection function, including a surgical membrane body, a surgical opening in the middle of the surgical membrane body, a pressure-sensitive rubber ring fixedly installed at the bottom of the surgical opening, a support component fixedly installed in the middle of the upper surface of the surgical membrane body for lifting the surgical membrane body to form a liquid collection area, a collection area formed by the periphery of the support component and the edge of the surgical membrane body, a liquid outlet channel inserted into the end of the collection area, and auxiliary fixing components fixedly installed at the four corners of the surgical membrane body; negative adhesive tape is glued to the bottom surface of the surgical membrane body, the support component includes a sealing sleeve and an aluminum core wire, the sealing sleeve is square and fixedly installed on the upper surface of the surgical membrane body, the aluminum core wire is square and embedded in the inside of the sealing sleeve, a handle ring is fixedly fixed in the middle of each side of the aluminum core wire, and rubber frames for liquid flow are fixedly installed at the four corners of the inside of the surgical membrane body and the four corners of the aluminum core wire.

[0007] As a preferred technical solution of this utility model, the collection area includes waste liquid area one, waste liquid area two, waste liquid area three and waste liquid area four. A flow port is opened in the middle of the rubber frame. Waste liquid area one is located on the upper part of the surgical membrane body and between the two sets of rubber frames. Waste liquid area two and waste liquid area four are located on both sides of the surgical membrane body and between the two sets of rubber frames. Waste liquid area four is located on the lower part of the surgical membrane body and between the two sets of rubber frames.

[0008] As a preferred technical solution of this utility model, the liquid outlet channel is fixedly installed at the four sides below the waste liquid area. The liquid outlet channel includes a drain pipe and a press-type cross valve. The drain pipe is inserted into the end of the surgical membrane body and is connected to the surgical membrane body. The press-type cross valve is inserted into the inside of the drain pipe.

[0009] As a preferred technical solution of this utility model, the auxiliary fixing component includes rubber rings and self-adhesive straps. The rubber rings are glued and installed at the four corners of the surgical membrane body. The self-adhesive straps are sleeved and installed in the middle of the rubber rings. One end of the self-adhesive straps is fixedly installed with a buckle block, and the other end of the self-adhesive straps can be inserted and installed around the buckle block.

[0010] As a preferred technical solution of this utility model, the self-adhesive strap is a double-sided self-adhesive Velcro that can be knotted on the surface of the surgical gown.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] The collection and dispensing zones formed by the aluminum core wire effectively collect blood and waste fluid generated during surgery, preventing blood from flowing around on the operating table and maintaining a clean and hygienic surgical environment. The rubber frame design ensures smooth flow of fluid between different areas inside the surgical membrane, improving the efficiency of waste fluid collection. The pressure-sensitive adhesive ring at the bottom of the surgical incision and the negative adhesive tape at the bottom of the surgical membrane body firmly adhere the surgical membrane to the patient's skin and surgical drape, preventing displacement during surgery and ensuring effective coverage and protection of the surgical site. The auxiliary fixation components further enhance the fixation effect of the surgical membrane, ensuring that even under certain external forces during surgery, the surgical membrane remains stable. Maintaining stability and timely collection and drainage of blood and waste fluid generated during surgery reduces the chance of blood coming into contact with the surgical incision, lowering the risk of postoperative wound infection. The sterile design of the surgical membrane effectively prevents external bacteria from entering the surgical site, further ensuring surgical safety. Effective blood collection and suction of waste fluid reduce contamination of the surgeon's surgical gown by blood and pollutants, lowering the occupational exposure risk for medical staff. The handle design on the support component facilitates operation by surgical personnel and can quickly form a collection area. The plug-in installation of the drainage channel is simple and easy to implement, allowing for connection of a suction device or direct drainage of waste fluid as needed during surgery.

Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a sterile surgical membrane with blood collection function, including a surgical membrane body 1, a surgical opening 11 in the middle of the surgical membrane body 1, a pressure-sensitive rubber ring 12 fixedly installed at the bottom of the surgical opening 11, a support component 2 for lifting the surgical membrane body 1 to form a liquid collection area fixedly installed in the middle of the upper surface of the surgical membrane body 1, a collection area 3 is formed around the support component 2 and the edge of the surgical membrane body 1, a liquid outlet channel 4 is inserted into the end of the collection area 3, and auxiliary fixing components 5 are fixedly installed at the four corners of the surgical membrane body 1; negative adhesive tape 13 is glued to the bottom surface of the surgical membrane body 1, the support component 2 includes a sealing sleeve 21 and an aluminum core wire 22, the sealing sleeve 21 is square and fixedly installed on the upper surface of the surgical membrane body 1, the aluminum core wire 22 is square and embedded in the inside of the sealing sleeve 21, a handle ring 221 is fixedly fixed in the middle of each side of the aluminum core wire 22, and rubber frames 14 for liquid flow are fixedly installed at the four corners of the inside of the surgical membrane body 1 and the four corners of the aluminum core wire 22.

[0021] like Figure 3As shown, in this case, the surgical opening 11 of the surgical membrane body 1 is located in the middle of the surgical membrane body 1, providing a channel for surgical operation. The pressure-sensitive adhesive ring 12 is fixedly installed at the bottom of the surgical opening 11 to tightly bond the surgical membrane to the patient's skin. The negative adhesive tape 13 is a large piece of adhesive glued to the bottom surface of the surgical membrane body 1, which facilitates the pasting of the surgical membrane onto the surgical drape and further fixes the overall position of the surgical membrane. The sealing sleeve 21 of the support component 2 is square and fixedly installed on the upper surface of the surgical membrane body 1, which plays the role of protecting and fixing the aluminum core wire 22, while ensuring the airtightness of the surgical membrane body 1. The aluminum core wire 22 is square and embedded inside the sealing sleeve 21. A handle ring 221 is fixed in sequence at the middle of each side of the aluminum core wire 22. By pulling the handle ring 221, the aluminum core wire can be lifted. Lifting 22 causes the surgical membrane body 1 to form a collection area, facilitating the collection of blood and waste fluid generated during the operation. The collection area 3 is formed by the perimeter of the support component 2 and the edge of the surgical membrane body 1, and is used to collect blood and waste fluid generated during the operation. The discharge channel 4 is inserted and installed at the end of the collection area 3. When the waste fluid in the collection area 3 reaches a certain amount, it can be discharged through the discharge channel 4. The auxiliary fixing component 5 is fixedly installed at the four corners of the surgical membrane body 1 to further enhance the fixing effect of the surgical membrane and prevent the surgical membrane from moving due to external force during the operation. Rubber frames 14 are fixedly installed at the four corners of the inside of the surgical membrane body 1 and the four corners of the aluminum core wire 22 for the flow of liquid between different areas inside the surgical membrane, ensuring that the waste fluid can flow smoothly into the collection area 3.

[0022] Usage Procedure: Check that the surgical membrane body 1, support component 2, fluid outlet channel 4, auxiliary fixing component 5, and other components are intact and undamaged, ensuring that each component is in normal working order. Lay the surgical drape flat on the operating table. Determine the position of the surgical incision 11 according to the surgical site. Attach the surgical membrane. Remove the protective film from the negative adhesive tape 13 at the bottom of the surgical membrane body 1. Attach the surgical membrane body 1 to the surgical drape, ensuring that the surgical incision 11 is aligned with the surgical site. Gently press the surgical membrane body 1 to ensure it adheres tightly to the surgical drape and the patient's skin. Pay particular attention to ensuring the pressure-sensitive adhesive ring 12 at the bottom of the surgical incision 11 is in full contact with the patient's skin to prevent leakage. Fix the auxiliary fixing component 5 at the four corners of the surgical membrane body 1. A tie-on method can be used for fixation to further enhance the stability of the surgical membrane. The surgeon can then lift the middle of each side aluminum core wire 22 on the support component 2. The handle 221 lifts the aluminum core wire 22, causing the surgical membrane body 1 to form a collection area. Blood and waste fluid generated during the operation will flow into the collection area 3. The outlet channel 4 is inserted and installed at the end of the collection area 3 to ensure a tight connection and prevent waste fluid leakage. During the operation, the blood and waste fluid generated will flow along the surgical membrane body 1 into the periphery of the collection area 3 and circulate between the areas through the rubber frame 14, finally flowing into the bottom of the collection area 3. When the waste fluid at the bottom of the collection area 3 reaches a certain amount, it can be discharged through the outlet channel 4. If there is a lot of waste fluid, the suction device can also be connected to the outlet channel 4 to remove the waste fluid in time by negative pressure suction. After the operation, first turn off the suction device, then untie the auxiliary fixing components 5 in sequence, gently lift the surgical membrane body 1, remove the surgical membrane from the surgical drape and the patient's skin, and dispose of it in accordance with the medical waste disposal regulations.

[0023] This sterile surgical membrane, through the collection area 3 formed by the aluminum core wire 22, can effectively collect blood and waste fluid generated during surgery, preventing blood from flowing around on the operating table and maintaining a clean and hygienic surgical environment. The design of the rubber frame 14 ensures smooth flow of liquid between different areas inside the surgical membrane, improving the efficiency of waste fluid collection. The pressure-sensitive adhesive ring 12 at the bottom of the surgical opening 11 and the negative adhesive tape 13 at the bottom of the surgical membrane body 1 can firmly adhere the surgical membrane to the patient's skin and surgical drape, preventing the surgical membrane from shifting during surgery and ensuring effective coverage and protection of the surgical site. The auxiliary fixing component 5 further enhances the fixing effect of the surgical membrane, even when subjected to certain external forces during surgery. The surgical membrane remains stable, allowing for timely collection and drainage of blood and waste fluid generated during surgery. This reduces the chance of blood coming into contact with the surgical incision, lowering the risk of postoperative wound infection. The aseptic design of the surgical membrane effectively prevents external bacteria from entering the surgical site, further ensuring surgical safety. By effectively collecting blood and using a suction device to remove waste fluid, it reduces the contamination of the surgeon's surgical gown by blood and pollutants, lowering the occupational exposure risk for medical staff. The handle 221 on the support component 2 is designed for easy operation by surgical personnel and can quickly form a collection area. The plug-in installation of the discharge channel 4 is simple and easy to implement, facilitating the connection of a suction device or direct drainage of waste fluid as needed during surgery.

[0024] The collection area 3 includes waste liquid area 1 31, waste liquid area 2 32, waste liquid area 33 and waste liquid area 4 34. A flow port 141 is provided in the middle of the rubber frame 14. Waste liquid area 1 31 is located on the upper part of the surgical membrane body 1 and between the two sets of rubber frames 14. Waste liquid area 2 32 and waste liquid area 4 34 are located on both sides of the surgical membrane body 1 and between the two sets of rubber frames 14. Waste liquid area 4 34 is located on the lower part of the surgical membrane body 1 and between the two sets of rubber frames 14.

[0025] like Figure 4As shown, in this case, waste liquid area 1 (31) is located at the upper part of the surgical membrane body 1 and between the two sets of rubber frames 14. During the operation, blood and waste liquid generated above the surgical site will flow downwards due to gravity. Waste liquid area 1 (31) can effectively receive this liquid, preventing it from spreading outside the surgical area and ensuring a clear surgical field. Waste liquid area 2 (32) is located on one side of the surgical membrane body 1 and between the two sets of rubber frames 14. Waste liquid area 33 is located on the other side of the surgical membrane body 1 and between the two sets of rubber frames 14. When the surgical operation involves one side of the surgical site, the generated waste liquid will flow to both sides of waste liquid area 2 (32) and waste liquid area 33 (33) to prevent it from contaminating the operating table or other areas. Waste liquid area 4 (34) Located at the lower part of the surgical membrane body 1 and between the two sets of rubber frames 14, waste fluid will naturally flow downwards during the operation. Waste fluid zone 34 serves as the main waste fluid collection area, capable of accommodating a large amount of waste fluid and reducing the risk of waste fluid overflow. The four waste fluid zones work together to form a three-dimensional waste fluid collection system. The rubber frames 14 divide the surgical membrane body 1 into different waste fluid zones, clearly defining the boundaries of each zone, allowing waste fluid to be collected within specific areas, preventing waste fluid from flowing randomly between different areas, and improving the targeting and effectiveness of waste fluid collection. During the operation, even if subjected to certain external forces, the surgical membrane body 1 can remain relatively flat, ensuring that waste fluid can flow smoothly into each waste fluid zone.

[0026] like Figure 5 As shown, the liquid outlet channel 4 is fixedly installed below the waste liquid area 34. The liquid outlet channel 4 includes a drain pipe 41 and a press-type cross valve 42. The drain pipe 41 is inserted into the end of the surgical membrane body 1 and is connected to the surgical membrane body 1. The press-type cross valve 42 is inserted into the inside of the drain pipe 41.

[0027] In this case, the discharge channel 4 is fixedly installed below the waste liquid area 34, which can make full use of the gravity of the waste liquid, allowing the waste liquid collected in the waste liquid area 34 to flow more smoothly into the discharge channel 4, reducing the residue of waste liquid in the surgical membrane body 1, improving the efficiency of waste liquid discharge, ensuring that the surgical area is always kept relatively clean, and providing a good environment for surgical operation. The drain pipe 41 is fixed to the end of the surgical membrane body 1 by plug-in installation, which facilitates assembly during the production process of the surgical membrane. The drain pipe 41 is connected to the surgical membrane body 1 through, ensuring that the waste liquid can flow smoothly from the collection area 3 inside the surgical membrane body 1 into the drain pipe 41, reducing the waste liquid residue in the connection. The accumulation of waste fluid reduces the risk of infection or disruption to surgical procedures caused by waste fluid buildup. The press-type cross valve 42 adopts a cross structure design, which can better control the flow of waste fluid. When the valve is closed, the cross structure can tightly fit the inner wall of the drain pipe 41 to prevent waste fluid from flowing out. When the waste fluid area 34 of the collection area 3 is full and waste fluid needs to be drained, the cross structure will open by pressing, allowing the waste fluid to pass smoothly. The controllable drainage method can prevent waste fluid from flowing out randomly during the operation, reduce pollution to the surgical environment, and also make it easier for surgical personnel to operate flexibly according to the actual situation, improving the efficiency and safety of the operation.

[0028] The auxiliary fixation component 5 includes rubber rings 51 and self-adhesive straps 52. The rubber rings 51 are glued to the four corners of the surgical membrane body 1. The self-adhesive straps 52 are sleeved on the middle of the rubber rings 51. One end of the self-adhesive straps 52 is fixedly installed with a buckle block 521, and the other end of the self-adhesive straps 52 can be inserted around and installed inside the buckle block 521.

[0029] like Figure 5As shown, in this case, the rubber rings 51 are installed at the four corners of the surgical membrane body 1 using an adhesive bonding method. Adhesive bonding provides a strong connection and good sealing, ensuring a tight bond between the rubber rings 51 and the surgical membrane body 1, preventing them from easily falling off. This provides a stable support base for the subsequent installation and use of the self-adhesive bandages 52. The rubber rings 51 have a certain degree of elasticity and softness, acting as a buffer between the surgical membrane body 1 and the patient's skin or surgical drape, reducing friction and damage caused to the patient's skin or surgical drape due to the hard edges of the surgical membrane body 1. The circular structure of the rubber rings 51 can distribute the pressure applied by the self-adhesive bandages 52, avoiding excessive local pressure and improving patient comfort. The self-adhesive bandages 52 are fitted around the center of the rubber rings 51, allowing for flexible adjustment around the rubber rings 51. This facilitates adjusting the tightness of the bandage according to actual needs, adapting to different patients. To meet the requirements of body shape and surgical site, one end of the self-adhesive bandage 52 is fixedly installed with a buckle block 521, and the other end can be inserted around and installed inside the buckle block 521. The design of the buckle block 521 makes it easier and faster to fix the self-adhesive bandage 52. Simply insert one end of the bandage into the buckle block 521 to fix the bandage. No additional tools or complicated operation steps are required. The self-adhesive bandage 52 itself is self-adhesive. During the bandage wrapping process, its surfaces can stick to each other, further enhancing the fixation effect of the bandage and preventing the bandage from loosening or falling off during the operation. The main function of the self-adhesive bandage 52 is to enhance the fixation effect of the surgical membrane body 1. By wrapping and fixing the self-adhesive bandage 52 around and onto the patient's body or surgical drape, the surgical membrane body 1 can be more tightly attached to the surgical site, preventing the surgical membrane from shifting during the operation, ensuring effective coverage and protection of the surgical site, and ensuring the smooth progress of the operation.

[0030] Self-adhesive bandage 52 is a double-sided self-adhesive Velcro that can be knotted onto the surface of the surgical gown.

[0031] In this case, the self-adhesive strap 52 is knotted on the surface of the surgical gown, which is equivalent to establishing an additional fixing point between the surgical membrane body 1 and the surgical gown. Compared with simply relying on the rubber ring 51 and Velcro, multi-point fixing can more effectively disperse external forces and prevent the surgical membrane from shifting due to pulling or collision. During the operation, if the surgeon accidentally touches the surgical membrane, multi-point fixing can reduce the amplitude of the surgical membrane's shaking and maintain the stability of the surgical site.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
