Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a chest compression bandage for breast mass puncture and minimally invasive surgery. Background Technology
[0002] Breast lumps are a common health problem for women, and accurate diagnosis of their nature is crucial for subsequent treatment. Currently, breast biopsy, especially core needle biopsy, is widely used in clinical practice as the gold standard for obtaining breast tissue samples. This procedure involves inserting a needle into the breast lump to obtain strips of tissue for pathological analysis. After the puncture, timely and effective compression to stop bleeding at the puncture site and deep channels is a core step in preventing postoperative complications, especially hematoma formation.
[0003] Currently, the standard compression method commonly used in clinical practice is to place a gauze pad at the skin puncture point and then use an elastic bandage to apply pressure to the patient's entire chest cavity.
[0004] However, traditional compression methods concentrate pressure primarily on the puncture site in the epidermis, essentially blocking the exit. The real risk of bleeding after puncture is not the capillaries in the epidermis, but rather the tiny blood vessels along the puncture channel deep within the breast that may be damaged. Simply blocking the epidermal puncture site is only a temporary solution and cannot create effective closure pressure in the deep channel. This easily leads to continuous blood seepage and accumulation within the tissue, unable to drain. Furthermore, after compression bandaging, the patient's chest undergoes rhythmic rise and fall with respiration. This continuous tissue displacement and shearing force constantly disturbs the fragile blood clot forming within the deep puncture channel, exacerbating internal bleeding. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a chest compression bandage for use after breast mass puncture and minimally invasive surgery.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] The compression module has an annular compression structure that defines a through-center observation channel.
[0011] The support body is provided with an observation window, the position of which corresponds to the central observation channel of the compression module;

This greatly improves wearing comfort while ensuring the compression effect. More importantly, during the user's breathing, the floating mechanism can dynamically adapt to tissue displacement caused by the rhythmic rise and fall of the chest, ensuring that the pressure is always evenly applied to the target area. This avoids the problem of excessive local pressure caused by a mismatch between the rigid structure and the body contour or respiratory movements, which can exacerbate bleeding.

Detailed Implementation
[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0046] Please see Figures 1-5 As shown, the specific embodiments provided by this utility model are as follows:
[0047] like Figures 1 to 2 As shown in the figure, an embodiment of the present invention proposes a chest compression bandage for use after breast mass puncture and minimally invasive surgery, including a support body 1 and a compression module.
[0048] Specifically, the support body 1 is the basic load-bearing part of the strap, and it is a garment that the user can comfortably wear on the chest, such as a vest or a wire-free bra. It is made of soft and elastic fabric, conforming to the user's body curves and providing overall support. At the front of the support body 1, corresponding to the area of the user's breast, an observation window 101 is provided. This observation window 101 is a pre-designed opening on the support body 1, providing medical personnel with a convenient channel for observation without removing the entire support body 1.
[0049] Specifically, the compression module is a component that achieves the function of compression hemostasis. The compression module is detachably installed on the inner side of the support body 1 through a releasable fastening method, thereby allowing the compression module to be flexibly installed according to the specific location of the puncture point (e.g., the left or right breast).
[0050] The main structure of the compression module is a ring-shaped compression structure 2. Unlike traditional solid planar compression methods, this ring-shaped compression structure 2 is hollow and annular. Its purpose is to apply pressure to the annular area around the puncture point to effectively compress deep tissues and blood vessels, rather than directly acting on the epidermal wound. The hollow portion of this ring-shaped compression structure 2 defines and forms a central observation channel 201 that runs through its upper and lower ends.
[0051] In use, the compression module is installed inside the support body 1, with its central observation channel 201 corresponding to the observation window 101 on the support body 1. Thus, when medical personnel need to examine the patient, their line of sight can pass sequentially through the observation window 101 on the support body 1 and the central observation channel 201 of the compression module, allowing direct observation of the puncture point area below.
[0052] like Figure 3 As shown, based on the above, the compression module also integrates a floating mechanism 3. This floating mechanism 3 connects the annular compression structure 2 to the support body 1 in a non-rigid manner. The function of this floating mechanism 3 is to allow the annular compression structure 2 to float and deflect relative to the support body 1 at multiple angles and within a small range when subjected to external force. When the user wears this strap, the annular compression structure 2 can adaptively conform to the unique physiological curves of the user's chest and breast surface, ensuring uniform pressure distribution and avoiding excessive local pressure or gaps caused by a mismatch between the rigid structure and the body contour. This greatly improves wearing comfort while ensuring the compression effect. More importantly, during the user's breathing, the floating mechanism 3 can dynamically adapt to tissue displacement caused by the rhythmic rise and fall of the chest, ensuring that the pressure is always applied evenly to the target area, avoiding the problem of excessive local pressure caused by a mismatch between the rigid structure and the body contour or respiratory movements, which could exacerbate bleeding.
[0053] like Figure 2 As shown, in a preferred embodiment, the annular compression structure 2 includes, from the outside to the inside, the following components stacked sequentially: an annular base 202, an annular airbag 203, an annular buffer pad 204, and a skin contact layer 205.
[0054] Specifically, the annular base 202 constitutes the supporting skeleton of the entire annular compression structure 2, and has a certain rigidity to ensure that the pressure generated by the annular airbag 203 can be effectively transmitted downward.
[0055] Specifically, an annular airbag 203 is disposed on the annular base 202. The annular airbag 203 is a sealed hollow cavity designed to regulate and control the pressure applied to the user's body by inflating or deflating gas.
[0056] Specifically, an annular cushioning pad 204 is further provided above the annular airbag 203. This annular cushioning pad 204 is typically made of a flexible material (such as memory foam) with slow rebound properties. Its function is to even out the point or linear pressure from the annular airbag 203 into a gentle planar pressure, and to absorb minor impacts from body activity or breathing, thereby preventing excessive local pressure and improving wearing comfort.
[0057] The innermost layer, which is in direct contact with the user (of the dressing), is the skin contact layer 205. This skin contact layer 205 is preferably made of a soft, biocompatible material (such as medical-grade silicone gel) to ensure comfort and safety during wear. Furthermore, the skin contact layer 205 supports and secures the transparent medical dressing placed thereon, preventing displacement of the dressing during wear and activity, thus ensuring the stability and effectiveness of the entire compression system.
[0058] In a preferred embodiment, a pressure regulating assembly is included, which consists of a manual air pump and a pressure gauge.
[0059] The manual air pump is preferably a small, balloon-type air pump that can be operated with one hand by medical personnel or users. The pressure gauge is preferably a pointer-type or digital pressure gauge with clear graduations, capable of displaying the pressure value in the air circuit in real time and intuitively.
[0060] The manual air pump, pressure gauge, and annular airbag 203 are interconnected through a flexible, airtight conduit, forming a complete, closed pneumatic circuit.
[0061] During use, the operator inflates the annular airbag 203 by repeatedly squeezing the manual air pump. During this process, the operator can continuously observe the values displayed on the pressure gauge. Inflation can be stopped when the pressure reaches the clinically required effective therapeutic pressure (e.g., 30-40 mmHg). Furthermore, a deflation valve can be integrated into the manual air pump for precise deflation adjustment of the annular airbag 203 when pressure needs to be reduced or the straps removed.
[0062] In a preferred embodiment, the annular base 202 consists of an outer support ring 2021 and an inner pressing ring 2022.
[0063] Specifically, the back of the outer support ring 2021 is used to connect to the inner side of the support body 1, thereby fixing the entire module in a preset position. The aforementioned pressure-applying components, such as the annular airbag 203, the annular buffer pad 204, and the skin contact layer 205, are all stacked and installed on the inner pressure ring 2022.
[0064] The floating mechanism 3 is located between the outer support ring 2021 and the inner pressure ring 2022. When the user wears this strap, the outer support ring 2021 remains relatively stationary with respect to the support body 1. The inner pressure ring 2022, which carries the pressure components, automatically adjusts its angle according to the actual contour of the user's body (e.g., chest, breast) below it, through the action of the floating mechanism 3, ensuring a uniform distribution of pressure.
[0065] More specifically, the floating mechanism 3 includes at least three (e.g., three or four) elastic pillars evenly distributed along the circumference of the outer support ring 2021 and the inner pressure ring 2022. These elastic pillars connect the inner and outer rings into a single unit. They are preferably made of a highly elastic polymer material such as medical-grade silicone. When the pressure module contacts the user's body, these elastic pillars undergo corresponding compression or stretching deformation according to the applied force, thereby supporting and allowing the inner pressure ring 2022 to tilt and deflect as a whole to conform to the body's contours.
[0066] Alternatively, the floating mechanism 3 may include a flexible cantilever. The flexible cantilever may have a specific curved profile (e.g., S-shaped or C-shaped) and achieves its floating function primarily through its own bending deformation.
[0067] like Figure 5 As shown, in a preferred embodiment, in order to ensure that the observation window 101 on the support body 1 can be aligned with the central observation channel 201 on the detachable compression module during use, a positioning mechanism 4 for positioning the compression module is also provided on the inner side of the support body 1.
[0068] Since the compression module can be disassembled and installed by the user, without a clear guidance mechanism, it is difficult to guarantee that the required alignment accuracy will be achieved every time it is installed. Therefore, this embodiment proposes the following alternative implementation schemes for the specific positioning mechanism 4:
[0069] The first approach is visual alignment marking. Specifically, a visual mark, such as a closed frame or a colored area, is created on the inner fabric of the support body 1 using processes like screen printing, heat transfer, or embroidery to perfectly match or closely resemble the outline of the compression module. When installing the compression module, the user simply aligns its edges with this visual mark for quick and accurate positioning.
[0070] The second approach uses loop fasteners for positioning and fixation. In this approach, a loop fastener matching the outline of the compression module is sewn or heat-pressed into a preset position on the inner side of the support body 1. Correspondingly, a hook-and-loop fastener is provided on the back of the compression module (i.e., the side away from the user's skin). During installation, the user presses the compression module onto the loop area, and the hook and loop engage, not only firmly fixing the module in the correct position but also effectively preventing it from slipping during subsequent wear and activities, thus providing both positioning and fixation functions.
[0071] The third approach uses magnetic positioning components for positioning. In this approach, at least one set of magnetic positioning components is respectively installed on the support body 1 and the compression module. For example, a first magnetic component (such as a magnet with the N pole facing outward) is implanted in the interlayer at the corresponding position on the inner side of the support body 1, and a second magnetic component (such as a magnet with the S pole facing outward) is implanted at the corresponding position on the compression module. When the compression module approaches the preset installation position, the attraction between the magnetic components will automatically guide the module to accurately return to its position.
[0072] like Figure 1 As shown, in a preferred embodiment, in order to improve the ease of putting on and taking off, the support body 1 has a front-opening structure 5 located in front of the chest.
[0073] In a preferred embodiment, the front opening structure 5 is specifically a Velcro structure.
[0074] Specifically, the support body 1 has a first side edge and a second side edge corresponding to each other at the opening in front of the chest. The inner surface of one side edge (e.g., the first side edge) is provided with a large area of hook-face fasteners; while the outer surface of the other side edge (e.g., the second side edge) is correspondingly provided with a large area of napped fasteners. When worn, the side edge with hooks can overlap the side edge with napped fasteners, achieving rapid closure through the interlocking of the hooks and napped fasteners.
[0075] In addition, since the hook and loop sides can fit together at any position within a wide range, the front opening structure 5 can adjust the tightness of the chest circumference of the support body 1 over a wide range.
[0076] like Figure 4 As shown, in a preferred embodiment, it also includes an openable cover 102 for closing or opening the observation window 101.
[0077] Specifically, the openable window cover 102 is preferably a fabric flap with the same or similar material as the support body 1, and one side edge of the flap is fixedly connected to one side edge of the observation window 101 (e.g., by sewing), thereby forming a structure that can be freely opened to expose the observation window 101 or closed to cover the observation window 101.
[0078] In another preferred embodiment, the openable window cover 102 is magnetically connected to the supporting body 1. That is, mutually attracting micro-magnetic elements are implanted in the interlayer of the free edges and / or corners of the window cover, and in the interlayer of the supporting body 1 at the corresponding positions around the observation window 101. When the window cover is lowered, the magnetic force causes it to automatically close. Of course, other connection methods, such as Velcro or snaps, can also be used.
[0079] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
