Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sterile surgical membrane for surgical procedures. 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] In addition to the surgical membrane itself, existing sterile surgical membranes generally include a collection bag and a fluid collection bag. The fluid collection bag is usually placed at the edge of the surgical opening of the surgical membrane and is used to collect blood flowing from the surgical patient's wound and irrigation fluid used to rinse the wound during the operation. The fluid collection bag is connected to the collection bag, and the waste liquid collected in the collection bag can be transported to the collection bag through a pipeline and stored.

[0004] However, the surface of a sterile surgical diaphragm is not smooth after it is applied to the surgical site; it has a certain arc or concave structure. Therefore, the irrigation waste fluid during surgery will not flow only along the direction of the collection bag, but will flow down from all sides of the sterile surgical diaphragm. Moreover, only a small portion is likely to enter the collection bag, while most will leak sideways, soaking the sterile surgical drapes. Therefore, it is necessary to design a sterile surgical diaphragm for surgical procedures to solve the above problems. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a sterile surgical membrane for surgical procedures.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sterile surgical membrane for surgical procedures, comprising: a surgical membrane body, a flow guiding component located on the surgical membrane body, and a liquid collection component connected to the flow guiding component;

[0007] The surgical membrane body has an operating hole, and the flow guiding component is located around the operating hole;

[0008] The flow guiding component includes: an irregularly shaped annular airbag, an annular plate located in the middle of the irregularly shaped annular airbag, and a flow guiding plate located between the annular plate and the irregularly shaped annular airbag; the annular plate has a circular hole in the middle that communicates with the operating hole, and an air inlet is provided on one side of the irregularly shaped annular airbag;

[0009] The fluid collection assembly includes: a drainage bag located on one side of the irregularly shaped annular airbag, a fluid collection bag located away from the surgical membrane body, and a guide tube connecting the drainage bag and the fluid collection bag.

[0010] In a preferred embodiment of the present invention, the liquid collection assembly further includes a buffer tube located between the drainage bag and the liquid collection bag, the buffer tube dividing the guide tube into two sections, and the two ends of the buffer tube respectively communicating with one of the sections of the guide tube;

[0011] The buffer tube has a hollow structure, and a float is installed inside the buffer tube.

[0012] In a preferred embodiment of this invention, the diameter of the float is larger than the inner diameter of the guide tube.

[0013] In a preferred embodiment of this utility model, the irregularly shaped annular airbag is an open annular shape with its opening facing the drainage bag, and several guide rods are provided at the opening position of the irregularly shaped annular airbag.

[0014] In a preferred embodiment of this utility model, the guide plate is an open annular shape, the size of which is the same as the size of the opening of the irregular annular airbag, and is connected to the annular plate and the irregular annular airbag respectively. The guide plate is an airbag structure and is in communication with the irregular annular airbag.

[0015] In a preferred embodiment of this utility model, the guide vane is provided with a guide groove, and the horizontal height of the guide groove on the side away from the opening position gradually decreases towards the opening position of the guide vane.

[0016] In a preferred embodiment of this invention, the horizontal height of the outer diameter of the annular plate is higher than the horizontal height of the guide plate, and the horizontal height of the outer diameter of the annular plate gradually increases towards the inner diameter.

[0017] In a preferred embodiment of this utility model, the two sides of the guide groove are provided with flow-guiding chamfers.

[0018] In a preferred embodiment of the present invention, an adhesive layer is provided at the bottom of the flow guiding component, and the flow guiding component is fixed to the surgical membrane body through the adhesive layer.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a sterile surgical membrane for surgical procedures. By setting up an irregularly shaped annular airbag, annular sheet and guide sheet, and combining the spatial layout of the annular sheet and guide sheet, a three-dimensional guide path is formed. The irregularly shaped annular airbag intercepts the irrigation waste liquid during the operation and collects it at the position of the guide sheet. The guide sheet guides the irrigation waste liquid to the collection component, which avoids the irrigation waste liquid from flowing from the periphery of the sterile surgical membrane during the operation, thereby realizing the centralized and continuous collection of irrigation waste liquid during the operation.

[0021] (2) By setting up a buffer tube and a float, the present invention uses the buffer tube as an intermediate buffer in the flow channel to temporarily store liquid during the flow of waste liquid, effectively reducing the reverse impact force of fluid caused by external pressure or back suction. When the liquid has a backflow tendency, the float automatically floats up and approaches the opening of the flow channel to form a physical barrier, which can automatically block the backflow path and prevent the backflow of irrigation waste liquid during or after operation due to pressure fluctuations or overflow of the collection bag, thereby contaminating the surgical area or interfering with the drainage effect.

[0022] (3) This utility model uses an open circular ring structure for the guide plate, which is arranged around the operating hole. It can work together with the ring plate and the irregular ring-shaped airbag to form a stable three-dimensional guide channel, effectively collecting body fluid or irrigation fluid that overflows from the periphery of the operating hole during the operation. The guide groove is set on the surface of the guide plate. Its groove is designed as an inclined structure that gradually decreases from the side away from the opening to the opening position, so that the liquid naturally converges under the action of gravity and flows along the guide direction, thereby realizing the directional discharge of liquid during the operation, preventing liquid stagnation or lateral diffusion, and effectively reducing the risk of surgical area contamination caused by liquid accumulation.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] like Figure 1 and Figure 2 As shown, a sterile surgical membrane for surgical procedures includes: a surgical membrane body 1, a flow guiding component located in the surgical membrane body 1, and a liquid collection component communicating with the flow guiding component.

[0033] An operation hole 2 is provided on the surgical membrane body 1, and the flow guiding component is located around the operation hole 2;

[0034] The flow guiding component includes: an irregularly shaped annular airbag 3, an annular plate 4 located in the middle of the irregularly shaped annular airbag 3, and a flow guiding plate 5 located between the annular plate 4 and the irregularly shaped annular airbag 3; the annular plate 4 has a circular hole in the middle that communicates with the operation hole 2, and an air inlet is provided on one side of the irregularly shaped annular airbag 3.

[0035] The fluid collection assembly includes: a drainage bag 6 located on one side of the irregular annular airbag 3, a fluid collection bag 7 located away from the surgical membrane body 1, and a guide tube 8 connecting the drainage bag 6 and the fluid collection bag 7.

[0036] It should be noted that an adhesive layer is provided at the bottom of the diversion component, and the diversion component is fixed to the surgical membrane body 1 through the adhesive layer.

[0037] The guide vane 5 is an airbag structure and is connected to the irregularly shaped annular airbag 3.

[0038] The irregularly shaped annular airbag 3 is an open annular shape with its opening facing the drainage bag 6, and several guide rods 11 are provided at the opening position of the irregularly shaped annular airbag 3.

[0039] During the use of sterile surgical membranes, the drainage component is attached to the surgical membrane through an adhesive layer, and the collection component is installed on the surgical membrane body 1. By inflating the irregularly shaped annular airbag 3, the irregularly shaped annular airbag 3 forms a compressible but not easily collapsed edge structure, where the impact waste liquid will collect, forming a waste flushing area, thus preventing the waste flushing liquid from spreading in all directions. Because the irregularly shaped annular airbag is an open ring shape, its opening direction faces the drainage bag 6. The collected waste flushing liquid will enter the drainage bag 6 through the guide rod 11 at the opening of the irregularly shaped annular airbag 3, and finally flow into the collection bag 7 through the drainage tube 8, completing the collection of the waste flushing liquid.

[0040] It is worth mentioning that, such as Figure 3 As shown, in this utility model, the liquid collection assembly also includes a buffer tube 9 located between the drainage bag 6 and the liquid collection bag 7. The buffer tube 9 divides the guide tube 8 into two sections, and the two ends of the buffer tube 9 are respectively connected to one of the sections of the guide tube 8.

[0041] The buffer tube 9 has a hollow structure, and a float 10 is installed inside the buffer tube 9.

[0042] The diameter of the float 10 is larger than the inner diameter of the guide tube 8.

[0043] When the irrigation waste fluid entering the drainage bag 6 passes through the guide tube 8, it first enters the buffer tube 9. The buffer tube 9 serves as an intermediate buffer in the drainage channel, temporarily storing the fluid during the flow of waste fluid. This effectively reduces the reverse impact force of the fluid caused by external pressure or backflow. When the liquid tends to flow back, the float ball 10 automatically floats up and approaches the opening of the guide tube 8, forming a physical barrier that can automatically block the backflow path. This prevents the irrigation waste fluid from flowing back during or after the operation due to pressure fluctuations or overflow of the collection bag 7, thus avoiding contamination of the surgical area or interference with the drainage effect.

[0044] In this invention, the guide plate 5 is an open annular shape, and its opening size is the same as that of the irregular annular airbag 3. It is connected to the annular plate 4 and the irregular annular airbag 3 respectively. The guide plate 5 is an airbag structure and is connected to the irregular annular airbag 3.

[0045] The guide vane 5 is provided with a guide groove 12, and the horizontal height of the guide groove 12 away from the opening position gradually decreases towards the opening position of the guide vane 5.

[0046] The guide plate 5, with its open annular structure, is arranged around the operating hole 2. It can work in conjunction with the annular plate 4 and the irregularly shaped annular airbag 3 to form a stable three-dimensional flow channel, effectively collecting body fluids or irrigation fluids that overflow from the periphery of the operating hole 2 during the operation. The guide groove 12 is set on the surface of the guide plate 5. Its groove design is an inclined structure that gradually decreases from the side away from the opening to the opening position, so that the liquid naturally converges under the action of gravity and flows along the guiding direction, thereby realizing the directional discharge of liquid during the operation, preventing liquid stagnation or lateral diffusion, and effectively reducing the risk of surgical area contamination caused by liquid accumulation.

[0047] In this invention, the horizontal height of the outer diameter of the annular plate 4 is higher than the horizontal height of the guide plate 5, and the horizontal height of the outer diameter of the annular plate 4 gradually increases towards the inner diameter.

[0048] The outer diameter of the annular plate 4 is higher than that of the guide plate 5, and gradually increases in the direction of the inner diameter, forming a natural inward sloping surface. Under the combined action of gravity and the guide groove 12, the liquid is guided to the position of the guide plate 5. Through the guide groove 12 on the guide plate 5, the liquid naturally converges under the action of gravity and flows along the guiding direction, thereby preventing the liquid from accumulating in the surgical area.

[0049] In this invention, the guide groove 12 has chamfered edges on both sides for drainage.

[0050] In use, the guide component is attached to the surgical membrane through an adhesive layer, and the liquid collection component is installed on the surgical membrane body 1. By inflating the irregular annular airbag 3, the irregular annular airbag 3 forms a compressible but not easily collapsed edge structure. With the setting of the annular plate 4, the impact waste liquid will accumulate between the annular plate 4 and the irregular annular airbag 3, forming a flushing waste liquid accumulation area. The guide plate 5 is provided with a guide groove 12, and the impact waste liquid will be introduced into the drainage bag 6 through the guide groove 12. When passing through the guide tube 8, it will first enter the buffer tube 9 and then enter the liquid collection bag 7 through the guide tube 8, thus completing the collection of flushing waste liquid.

[0051] When the collection bag 7 is subjected to external pressure or backflow, the flushing waste liquid in the collection bag 7 will flow back. The backflowing flushing waste liquid will enter the buffer tube 9. As the flushing waste liquid in the buffer tube 9 increases, it will cause the float 10 to float up until it moves to the inlet of the guide tube 8 connected to the buffer tube 9. Then, the buoyancy generated by the flushing waste liquid on the float 10 will block the inlet of the guide tube 8, forming a physical barrier. This can automatically block the backflow path and prevent the flushing waste liquid from flowing back during or after the operation due to pressure fluctuations or overflow of the collection bag 7.

[0052] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
