Description

Technical Field

[0001] This utility model relates to the field of surgical membranes, and more particularly to a surgical membrane with a liquid collection function. Background Technology

[0002] In traditional surgery, blood, irrigation fluid, and other fluids seeping from the surgical area can easily accumulate in the surgical field, not only interfering with the surgeon's view but also potentially increasing the risk of infection. Current surgical membranes mostly employ planar adsorption or simple grooved drainage designs.

[0003] A utility model patent with application number 202222740034.7 discloses a blood collection surgical membrane, which includes a surgical membrane body and a blood collection bag. The surgical membrane body has an operating opening, a cover layer, and a storage cavity. The operating opening is located in the middle of the surgical membrane body. The central axis of the cover layer is collinear with the central axis of the operating opening, and the cover layer completely covers the operating opening. The cover layer is detachably connected to the surgical membrane body. The storage cavity is integrally connected to the surgical membrane body and communicates with the blood collection bag through a conduit. Because the accompanying liquid collection device is often fixed with adhesive or straps, it is prone to detachment or membrane displacement due to sudden changes in tensile force when the liquid weight increases.

[0004] Therefore, it is necessary to improve a surgical membrane with a fluid collection function in the prior art to solve the above problems. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a surgical membrane with a liquid collection function, aiming to solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a surgical membrane with a fluid collection function, comprising:

[0007] Surgical membrane body;

[0008] The fluid collection lines are located on the surgical membrane body; the fluid collection lines are arranged in a spider web pattern, and are used to control the flow direction of fluid during surgery. The center of the fluid collection lines coincides with the center of the surgical membrane body; and...

[0009] A collection chamber is located around the surgical membrane body; the collection chamber is used to collect fluids during the surgical procedure.

[0010] In a preferred embodiment of this invention, the collection chamber is threadedly connected to the surgical membrane body, and each collection chamber is located at the end of the liquid collection line.

[0011] In a preferred embodiment of this utility model, the liquid collection line includes a ring-shaped line and several straight lines, with the straight lines intersecting and overlapping at a single point.

[0012] In a preferred embodiment of this utility model, the ring circuit includes several circular circuits, all of which are arranged in concentric circles.

[0013] In a preferred embodiment of this utility model, the straight line includes several central lines and several intersecting lines.

[0014] In a preferred embodiment of this utility model, a plurality of center lines are provided, and the plurality of center lines intersect at a point. The intersection point of the center lines is located at the center of the circular line, and the center lines penetrate the surgical membrane body.

[0015] In a preferred embodiment of this utility model, the intersecting line is a pointed cone with an open bottom. The pointed part of the intersecting line is located at the intersection of the circular line and the center line, and the opening of the intersecting line faces the center of the circular line.

[0016] In a preferred embodiment of this invention, the opening of the collecting cavity is threaded to the end of the center line.

[0017] In a preferred embodiment of this invention, a Velcro strap is provided on the side of the collection cavity, which is used to fix the collection cavity to the hospital bed.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a surgical membrane with a liquid collection function. The membrane achieves a sealed connection through the threaded connection structure between the collection cavity and the surgical membrane body. Combined with the dynamic fixing method of the Velcro with a preset stretching height, the Velcro is set on the side of the collection cavity and its stretching height is controlled in advance. When the weight of the liquid increases, the collection cavity gradually moves down through the controllable deformation of the Velcro. At the same time, the minimum downward movement is limited, thereby effectively avoiding the problem of the collection cavity becoming too heavy due to continuous liquid accumulation and pulling the surgical membrane body off. This ensures the stability of the surgical membrane during the operation and the continuity of liquid collection.

[0020] (2) This utility model provides a surgical membrane with a liquid collection function. By scattering concentric circular lines with the center point of the surgical membrane body as a reference and configuring intersecting lines that pass through the center and are symmetrically distributed in a pointed cone shape, a spider web-like liquid collection groove structure combining multiple rings and radial straight lines is formed. This allows the liquid to be quickly diverted to the collection cavity through the adjacent concentric circular grooves and intersecting lines after the central area of ​​the surgical membrane is cut, regardless of the size of the incision. This solves the problem of broken liquid flow path or low drainage efficiency caused by poor incision adaptability of traditional surgical membranes, and ensures that the liquid is efficiently and directionally collected under different incision sizes during the operation.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] As shown in the figure, a surgical membrane with liquid collection function has the following features:

[0027] Surgical membrane body 1;

[0028] A fluid collection line 2 is formed on the surgical membrane body 1; the fluid collection line 2 is arranged in a spider web pattern, and is used to control the flow direction of fluid during the operation; the center of the fluid collection line 2 coincides with the center of the surgical membrane body 1; and,

[0029] Collection cavity 3 is located around the surgical membrane body 1; collection cavity 3 is used to collect fluids during the operation.

[0030] It should be noted that the surgical membrane body 1, as the basic supporting layer, is made of medical polymer material, and its surface is formed into a three-dimensional topological structure through a three-dimensional molding process. The center point of the surgical membrane body 1 is also the geometric center of the liquid collection line 2. The liquid collection line 2 adopts the biomimetic principle to simulate the shape of a spider web and uses gravity to establish a liquid flow guidance mechanism.

[0031] In this invention, the liquid collection line 2 includes a ring-shaped line and several straight lines, with the straight lines intersecting and coinciding at a single point. The ring-shaped line includes several circular lines 20, all arranged concentrically. The straight lines include several central lines 21 and several intersecting lines 22. Several central lines 21 are provided, all intersecting at a single point, with the intersection point of the central lines 21 located at the center of the circular lines 20, and the central lines 21 penetrating the surgical membrane body 1. The intersecting lines 22 are cone-shaped with an open bottom, with the cone-shaped portion of the intersecting line 22 located at the intersection of the circular lines 20 and the central lines 21, and the opening of the intersecting line 22 facing the center of the circular lines 20.

[0032] It should be noted that the collection lines 2 are all distributed with the center point of the surgical membrane body 1 as the center point. The collection lines 2 are grooves etched on the surgical membrane body 1, which are used to allow the liquid to flow along the collection lines 2 when it is left behind by gravity during the operation, and then enter the collection chamber 3 for centralized treatment. The circular lines 20 are composed of several concentric circles, the center of which is the center of the surgical membrane body 1. The surgical membrane is a rectangular membrane, and before the operation, an opening is cut in the middle according to the size of the operation. Therefore, several The surgical membrane features concentric circles to accommodate different surgical wound sizes. Even after the center of the surgical membrane is removed, regardless of the wound size, the membrane still maintains concentric circular lines 20 centered on its center. This ensures that liquid flowing down under gravity will continue to flow onto these circular lines 20. Furthermore, the surgical membrane has several central lines 21 and intersecting lines 22. Both the central lines 21 and intersecting lines 22 are straight. The central lines 21 pass through the centers of the concentric circular lines 20, connecting the various circular lines 20 with different diameters. The intersecting lines 22 are cone-shaped. Its pointed tip is located at the intersection of the center line 21 and the circular line 20, and is symmetrically arranged about the center line 21. The end of the intersecting line 22 extends to the next nearest circular line 20 inside the circular line 20 where its pointed tip is located. This allows the circular line 20, the center line 21, and the intersecting line 22 to form a spiderweb-like fluid collection line 2 on the surgical membrane body 1. During use, medical personnel can cut the center of the surgical membrane body 1 as needed, and the circular line 20 can accommodate any size cut, regardless of the cut size. There is always a liquid collection line 2 around the circumference. When the size of the cut opening is exactly the same as the size of any circular line 20, the liquid flows directly into the circular line 20 under the action of gravity. It then enters different center lines 21 and cross lines 22 through the circular line 20 and is quickly diverted. Under the continuous diversion of several center lines 21 and cross lines 22, the liquid quickly flows to the collection chamber 3. When the cut opening is between two circular lines 20, the liquid enters the circular line 20 through several center lines 21 and cross lines 22 and is diverted again, so as to quickly disperse and collect the liquid.

[0033] In this invention, the collection chamber 3 is threadedly connected to the surgical membrane body 1, and each collection chamber 3 is located at the end of the collection line 2. The opening of the collection chamber 3 is threadedly connected to the end of the center line 21. Velcro 30 is provided on the side of the collection chamber 3 for fixing the collection chamber 3 to the hospital bed.

[0034] It should be noted that the connection structure between the collection chamber 3 and the surgical membrane body 1 adopts a standardized threaded interface design. Specifically, the opening end of the collection chamber 3 is injection molded from medical-grade polypropylene material, and the inner wall is machined with a precision trapezoidal thread of M12×1.25, which forms a sealed engagement with the 304L stainless steel threaded sleeve pre-embedded at the edge of the surgical membrane body 1. This design can achieve a 360° circumferential seal and can withstand a negative pressure environment of 50kPa without leakage under a torque of 3.5N·m. The thread engagement length is designed to be 7.2mm, which ensures both ease of disassembly and assembly and meets the requirements of the ISO 80369-7 liquid leak-proof standard. Each collection chamber 3 is precisely located within 1.5mm of the end of the liquid collection line 2, ensuring that a liquid level gradient is formed between the end of the guide path and the collection inlet.

[0035] A Velcro strap 30 is fixedly connected to one side of the collection chamber 3. During use, this device collects liquid by gravity. Therefore, before use, after attaching the surgical film to the patient's body, allow the device to hang naturally under gravity and record the height of the collection chamber 3 at this time (this height is the height of the device under gravity when there is no liquid, i.e., this height is S1). Then, use the Velcro strap 30 to fix the collection chamber 3. Before fixing, stretch the Velcro strap 30 and record the height of the collection chamber 3 when the Velcro strap 30 is stretched (recorded as this height is S2). Then fix the collection chamber 3 so that the Velcro strap 30 is stretched and then tightened. The height of the collecting chamber 3 is 2cm higher than the height of the Velcro 30 under the weight of the collecting chamber 3 alone (i.e., the height of S2 is 2cm higher than the height of S1). The Velcro 30 is used to fix the collecting chamber 3 in this way. During the operation, as the amount of liquid collected in the collecting chamber 3 gradually increases, the weight of the collecting chamber 3 increases, the Velcro 30 is stretched, and the height of the collecting chamber 3 gradually decreases. However, the lowest height of the collecting chamber 3 that decreases is still 2cm higher than the height when the device is only under the weight of gravity. This prevents the surgical membrane from gradually increasing in weight due to the increase of liquid in the collecting chamber 3, which could lead to the surgical membrane slipping off due to the collecting chamber 3.

[0036] 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.
