Description

Technical Field

[0001] The invention relates to the technical field of protective devices, and in particular to a thoracic surgical wound protective device. Background Art

[0002] After thoracic surgery, proper protection of the wound is crucial to the patient's recovery process. Traditional thoracic wound protection methods have many limitations. For example, ordinary bandages often only have simple covering and isolation functions, and lack special designs for the characteristics of thoracic surgical wounds. Its adhesiveness is easy to loosen due to the patient's frequent breathing and physical activities after surgery, and it cannot stably adhere to the skin around the wound, resulting in an increased risk of wound exposure, which is susceptible to infection caused by external bacteria and dust pollution, thereby delaying healing.

[0003] Furthermore, although common fixed bandages or chest straps can restrict chest movement and reduce wound tension to a certain extent, most of them are single wrap-around fixations, which are difficult to accurately adapt to the chest shape and wound position of different patients. This not only leads to poor fixation effect, but may also cause increased wound pain and tissue damage due to local compression or friction when the patient is active. In addition, it is uncomfortable and long-term wearing can easily cause complications such as skin allergies and poor blood circulation in patients, affecting the patient's quality of life and confidence in recovery after surgery. In addition, for wound dressing changes and observation operations, traditional protective devices usually need to be completely removed and bandaged. This process is cumbersome and time-consuming, which increases the patient's pain and the workload of medical staff, and also increases the probability of secondary infection of the wound. In view of these shortcomings, it is an urgent need to develop a thoracic surgical wound protection device that can fit tightly, provide firm protection, be easy to operate, and be comfortable and safe.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1-5 As shown, a thoracic surgical wound protection device proposed in one embodiment of the present invention comprises a wound patch 1, wherein the wound patch 1 is provided with an annular matrix groove 2, wherein the wound patch 1 is located at the center of a wound area 3, wherein the wound patch 1 is connected with a treatment replacement pack, wherein the treatment replacement pack comprises a lower cover 4 and an upper cover 5 connected to the wound patch 1, wherein a zipper 6 is sewn and installed between the lower cover 4 and the upper cover 5, and the zipper 6 is opened and closed by a zipper 7;

[0031] The side of the wound patch 1 is connected with a tensioning belt 8, and a bandage 9 is installed between the tensioning belts 8. The two ends of the bandage 9 are respectively wrapped around a sub-buckle 10 and a female buckle 11. The sub-buckle 10 and the female buckle 11 can be installed and removed. The bandage 9 can be telescopically adjusted to the diameter of different parts through the sub-buckle 10 and the female buckle 11;

[0032] A mounting patch 12 is fixed to the inner surface of the wound patch 1, and a matrix of notches 13 are provided on the mounting patch 12. An elastic connecting belt 14 is fixedly connected to the mounting patch 12, and a single-sided adhesive belt 15 is fixedly connected to the elastic connecting belt 14.

[0033] Wound Patch 1 is made of breathable and hypoallergenic medical non-woven fabric with a thickness of 0.2-0.5 mm. This material can ensure effective exchange between the wound and the outside air, maintain appropriate humidity and oxygen concentration, and promote aerobic metabolism of healing cells; hypoallergenicity reduces the risk of skin inflammation, creates a stable and safe healing microenvironment for the wound, and reduces factors that interfere with healing.

[0034] The design of the annular matrix groove 2 is distributed in a broken matrix around the wound patch 1 in multiple layers. When the surgical wound heals, there will be tissue fluid exudation, local micro-swelling and new tissue growth. The annular matrix groove 2 reserves space for tissue deformation, relieves swelling pressure, and prevents the wound patch 1 from over-pressing the wound and surrounding tissues. At the same time, it does not affect the overall protection stability and maintains a good wound healing state.

[0035] Treatment replacement bag: lower cover 4, upper cover 5, zipper 6, zipper 7;

[0036] Component coordination mechanism: The lower cover 4 is connected to the upper cover 5 by sew-up through the zipper 6, and the zipper 7 controls the opening and closing. This design builds an independent operation area for wound care. When changing the dressing or checking, the zipper 7 is pulled open to avoid removing the overall protective device, which greatly shortens the wound exposure time, reduces the infection rate, reduces the patient's pain and the workload of medical care, and improves the nursing efficiency and wound safety.

[0037] The tensioning belt 8 and the bandage 9, including the sub-buckle 10 and the mother buckle 11: the tensioning belt 8 is made of a blend of highly elastic natural rubber and spandex, with a tensile strength of 15-25 MPa and an elongation of 300%-500%, so that it can dynamically expand and contract with the patient's chest, such as during breathing and slight limb movements, and adaptively adjust the tension to buffer the pulling force on the wound, prevent wound tearing, promote the stable growth of healing tissue, and ensure the mechanical stability of protection.

[0038] Adjustment structure function: The two ends of the bandage 9 are wrapped around the sub-button 10 and the female buckle 11. The sub-button 10 and the female buckle 11 are easy to install and remove, and the length of the bandage 9 is adjustable. The chest size and wound position of different patients vary greatly. This design allows the bandage 9 to accurately adapt to the individual, tightly surround and fix the wound patch 1 and the treatment replacement bag to avoid loosening and slipping, ensure the accurate positioning of the protective device, and fit tightly, providing long-lasting and stable support for wound healing.

[0039] Installation sticker 12, notch 13, elastic connecting belt 14 and single-sided adhesive belt 15:

[0040] The installation patch 12 is placed on the periphery of the annular matrix groove 2 of the wound patch 1, and the single-sided adhesive tape 15 is filled in the gap 13 and the surface of the installation patch 12 via the elastic connecting tape 14. The installation patch 12 provides a stable base for the elastic connecting tape 14 and the single-sided adhesive tape 15, enhancing the integrity of the connection between the wound patch 1 and the skin; the elastic connecting tape 14 gives the single-sided adhesive tape 15 flexibility and elasticity, adapting to the stretching and wrinkling of the skin, preventing the edge of the adhesive tape from lifting and falling off, ensuring all-round and stable protection of the skin around the wound, assisting the wound patch 1 in evenly dispersing pressure, and optimizing the mechanical environment for wound healing.

[0041] When installing the present thoracic surgical wound protection device, first align the center of the wound patch 1 with the wound area 3 and gently stick it to the skin, and the annular matrix groove 2 adapts itself according to the contour of the wound. Then put the tension belt 8 in a suitable position, pass the bandage 9 through the tension belt 8, and its two ends are wrapped around the sub-button 10 and the mother buckle 11 according to the size of the chest and adjusted to a suitable tightness to fix. The lower cover 4 and the upper cover 5 are closed by the zipper 6 and the zipper 7 to form a treatment replacement package and connected to the wound patch 1. The elastic connecting belt 14 and the single-sided adhesive belt 15 on the installation patch 12 are flexibly adjusted through the notch 13 to fit the skin around the wound tightly, assist the wound patch 1 to be stable, ensure the synergy of the various components of the protection device, and provide reliable protection for wound healing.

[0042] like Figure 1As shown, in some embodiments, the annular matrix groove 2 is a broken matrix circumferentially distributed around the wound patch 1, and is provided with several grooves; this unique design contains exquisite principles and significant advantages. From the perspective of biomechanics, the healing process of thoracic surgery wounds is affected by a variety of mechanical factors, and the pulling force and squeezing force generated by the patient's daily breathing, chest ups and downs, and occasional body movements cannot be ignored. The annular matrix groove 2 constructs a criss-cross stress buffer network, and its broken layout is similar to a "joint", which gives the wound patch 1 local deformation ability. When external force is applied, the groove body flexibly deforms according to the direction of stress, guides the stress dispersion, avoids stress concentration on the wound, effectively reduces the abnormal pressure on the healing tissue, creates a stable mechanical microenvironment for wound repair cells, reduces the risk of wound tearing and delayed healing, and meets the biomechanical requirements of wound healing.

[0043] Considering the physiological environment of the wound, surgical wounds often have tissue fluid exudation, local congestion and swelling in the early stages of healing. The annular matrix groove 2 plays a similar role as a "drainage channel" and "decompression valve", opening up a channel for the discharge of tissue fluid and reserving expansion space for swollen tissue, avoiding the accumulation of effusion causing infection, swelling causing tight compression of the wound patch 1 and hindering blood circulation, maintaining moderate air permeability and humidity balance of the wound, ensuring the orderly advancement of the physiological process of wound healing, helping wound healing from the perspective of optimizing the physiological environment, and improving the adaptability and promotion of the protective device to the complex healing process of thoracic surgery wounds.

[0044] like Figure 1 As shown, in some embodiments, the bandage 9 passes through two tensioning bands 8 and covers the upper cover 5 to form a wraparound design, and the length of the bandage 9 can be adjusted; the wraparound design in which the bandage 9 passes through two tensioning bands 8 and covers the upper cover 5 builds a stable protective structure. In terms of mechanical stability, this design locks the wound patch 1 and the treatment replacement pack like a frame, forming a closed-loop constraint system around the chest. The tensioning band 8 serves as an elastic buffer hub, which moderately expands and contracts according to the dynamic movement of the patient's chest, and cooperates with the bandage 9 to accurately control the tightness of the protection. When the patient breathes, turns slightly or moves his upper limbs, the size and shape of the chest change, and the bandage 9 elastically deforms the tensioning band 8 to buffer the stress, maintain a constant protective pressure, prevent the wound from being disturbed by abnormal external forces, and ensure the stable growth of the healing tissue. Its wraparound path optimizes the stress distribution so that the protective force evenly covers the wound area.

[0045] The adjustable length of the bandage 9 lays a solid foundation for accurate adaptation to individual differences. Different patients have different chest circumferences, shapes, wound locations, and sizes, and fixed-length bandages 9 are difficult to be universal. The length adjustment function is achieved by the sub-buckle 10 and the mother buckle 11. Medical staff can flexibly adjust the surrounding dimensions of the bandage 9 according to the actual measurement of the patient's chest or on-site evaluation to ensure that the bandage 9 fits tightly without gaps, avoid loosening and slipping that may cause protection failure, ensure that the protective device accurately locates and firmly protects the wound of each patient, improve the practicality of the device and the comfort of the patient, and provide key support for the personalized and precise protection of thoracic surgical wounds.

[0046] like Figure 3 As shown, in some embodiments, the mounting patch 12 is arranged at the periphery of the annular matrix groove 2 of the wound patch 1; this layout is formed after in-depth consideration of the characteristics and protection requirements of thoracic surgery wounds, and contains multiple key functions. In terms of mechanical stability, although the annular matrix groove 2 reserves deformation buffer space for the wound, it may partially weaken the adhesion stability between the wound patch 1 and the skin. The mounting patch 12 forms a strong adhesion supplement area here, just like a "reinforced anchor point" surrounding the key parts around the wound. It works closely with the wound patch 1 to strengthen the overall adhesion structure with the skin. When encountering external force, it effectively limits the risk of warping and displacement of the edge of the wound patch 1, and ensures that the wound is balanced and stable through uniform stress transmission, building a strong defense line for wound healing cells from abnormal mechanical interference and stabilizing the mechanical environment required for the healing process.

[0047] From the perspective of skin adaptability, the skin around the wound may be sensitive and fragile after surgery, and is easily damaged by friction and pulling. The mounting patch 12 constructs a continuous and flat protective belt around the annular matrix groove 2 to reduce the probability of direct stimulation of the skin near the wound by external factors. And its position design avoids conflict with the key area of ​​wound healing, creates an independent and safe surrounding environment for the wound, prevents secondary damage or hinders the healing process due to the structure of the protective device itself, improves the wearing comfort and safety of the device, and realizes the meticulous care of the thoracic surgical wound and surrounding skin with a comprehensive layout.

[0048] like Figure 4 As shown, in some embodiments, the single-sided adhesive tape 15 is filled in the gap 13 and the surface of the mounting patch 12 through the elastic connecting tape 14; this structural layout is deeply rooted in the needs of improving protection performance and adaptability. The elastic connecting tape 14 acts as a flexible conductive medium, giving the single-sided adhesive tape 15 multi-dimensional adjustment capabilities. When the patient's skin undergoes microscopic deformation due to muscle activity and posture changes, the elastic connecting tape 14 responds in real time, pulling the single-sided adhesive tape 15 to adaptively adjust the fit, preventing the edge of the adhesive tape from floating and gaps from growing due to dynamic changes in the skin, and stabilizing the integrity of the protection system, ensuring that the wound is fully sealed and protected to resist the invasion of external pathogens.

[0049] At the filling level of the gap 13, the filling design eliminates the structural gap of the installation patch 12 and optimizes the stress transfer path. It evenly disperses the local stress to a wider skin area through the elastic connecting belt 14, buffers the impact of external forces, protects the wound from concentrated stress damage, and cooperates with the annular matrix groove 2 and the installation patch 12 to maintain stable mechanical support. When the surface of the installation patch 12 is covered, the single-sided adhesive tape 15 forms a complementary adhesion system with the installation patch 12 to enhance the durability of adhesion to the skin. The synergistic effect of multiple structures, with dynamic adaptation, seamless protection and stable adhesion characteristics, builds a precise and reliable protective barrier for the healing of thoracic surgical wounds, adapting to complex physiological and mechanical environmental changes.

[0050] like Figure 3 As shown, in some embodiments, the material of the wound patch 1 is a breathable and hypoallergenic medical non-woven fabric with a thickness ranging from 0.2 to 0.5 mm, which can ensure good ventilation of the wound while preventing skin allergic reactions, and ensure the stability and safety of the wound healing environment; this material has excellent air permeability. At the microscopic level, its fibers are interwoven to form a fine pore network, and air molecules shuttle smoothly to maintain a moderate oxygen partial pressure in the wound. The wound healing cells have active metabolism and need sufficient oxygen energy supply. This material is like an "invisible breathing channel" to ensure continuous aerobic respiration, accelerate cell proliferation and differentiation, collagen synthesis and new blood vessel growth, and promote the efficient evolution of the healing process.

[0051] The hypoallergenicity is of far-reaching significance, which stems from the selection of raw materials and fine processing technology. The raw materials are free of common allergenic impurities, and after special treatment, the surface is smooth and chemically inert, which minimizes the triggering of immune responses when in contact with the skin. The skin barrier is fragile after surgery, and hypoallergenicity effectively prevents allergic manifestations such as inflammation, itching, and erythema, avoids interruption or deterioration of wound healing, and protects the stability of the healing environment. The thickness setting is the result of a multi-factor trade-off. Too thick hinders gas exchange, increases foreign body sensation and difficulty in sweating; too thin reduces strength and protection. The 0.2-0.5 mm range reaches a balance, taking into account breathability, comfort and protection, laying a stable and safe foundation for wound healing, and promoting thoracic surgery wound repair in all directions with exquisite material properties.

[0052] like Figure 3As shown, in some embodiments, the tensioning band 8 is made of a blend of highly elastic natural rubber and spandex, with a tensile strength of 15-25 MPa and an elongation of 300%-500%. It can be flexibly stretched and retracted according to the patient's body movements, effectively dispersing the pressure around the wound, providing a stable mechanical environment for wound healing, and maintaining elastic recovery performance for long-term use; in the framework of material mechanics, the tensile strength of 15-25 MPa gives the tensioning band 8 a stable mechanical support foundation. This strength range has been optimized through rigorous testing. In extreme situations of daily activities, it can firmly maintain the position of the wound patch 1 and the bandage 9, counteract the sudden strong pulling force caused by the violent movement of the chest, prevent the displacement failure of the protective device from causing the risk of wound exposure to soar, and create a constant and stable physical barrier for wound healing.

[0053] The 300%-500% elongation is a core advantage, which means that the tensioning band 8 can smoothly expand and contract with the dynamic changes of the thorax. When the patient breathes, the thorax expands and contracts periodically, and daily limb movements cause the muscles to pull the thorax to deform. The tensioning band 8 can accurately sense and adaptively adjust the length and tension. It is like an intelligent buffer element that efficiently absorbs and evenly disperses stress to avoid stress waves focusing on the wound. In the dynamic process, the instantaneous high pressure concentrated around the wound is converted into a widely distributed low-stress field, which relieves the mechanical burden on the newly healed tissue, ensures the orderly growth and repair of fragile tissues, and stabilizes the mechanical environment of wound healing with a precise stress regulation mechanism.

[0054] Long-term elastic recovery performance enables continuous protection and endurance. During frequent reciprocating stretching and deformation, the excellent elastic memory of natural rubber cooperates with the stable molecular structure of spandex to ensure that the tensioning belt 8 returns to its initial state after multiple cycles. This feature avoids the hidden danger of elastic decay causing protective relaxation, maintains stable protection strength and precise fit for a long time, reduces the frequency of device adjustment during the wound care cycle, improves patient comfort and compliance, and fully protects the mechanical stability needs of thoracic surgical wounds from the acute stage of trauma to the complete healing stage.

[0055] like Figure 4 As shown, in some embodiments, the adhesive strength between the mounting patch 12 and the wound patch 1 is not less than 2 N / cm, and can maintain a stable attachment during the patient's activities, preventing the mounting patch 12 and the elastic connecting belt 14 and the single-sided adhesive belt 15 connected thereto from shifting, ensuring that the auxiliary fixation and protection of the skin around the wound is continuously effective, and maintaining the stability of the wound healing environment;

[0056] This adhesive strength has been optimized through a large number of experiments and clinical verifications, and is sufficient to cope with the complex stress challenges generated by patient activities. Patients have a variety of daily activities after surgery, and frequent chest movements, muscle pulling, skin stretching, sliding, etc., may all damage the attachment state of the protective device. The high-strength adhesive force is like a strong adhesive, constructing a stable connection interface between the installation patch 12 and the wound patch 1, ensuring close coordination between the two.

[0057] From the perspective of protection coordination, stable adhesion eliminates the risk of displacement of the installation patch 12 and the connected elastic connecting belt 14 and the single-sided adhesive belt 15. The elastic connecting belt 14 and the single-sided adhesive belt 15 can accurately perform their functions by stabilizing the base, continuously providing uniform and moderate pressure to the skin around the wound, assisting in fixing the tissue at the edge of the wound, dispersing local stress, and enhancing the overall protective effect of the wound patch 1. From the analysis of the wound healing process, a stable protective environment is a key factor. The stable structure supported by the adhesive strength maintains the physical stability required for wound healing, prevents interference from external factors such as accidental touch and clothing friction, creates continuous and undisturbed ideal conditions for cell proliferation and tissue remodeling, ensures that wound healing proceeds in an orderly manner according to the expected trajectory, and injects lasting and stable power into thoracic surgery wound repair with reliable adhesive performance.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
