Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a chest fixing belt after breast prosthesis implantation. Background Art

[0002] Breast implant placement is a common plastic surgery procedure, mainly used for breast reconstruction or breast augmentation. The surgery involves implanting a prosthesis under the breast tissue or under the pectoralis major muscle to improve the shape and volume of the breast. This surgery is suitable for breast reconstruction after breast cancer surgery, breast hypoplasia, breast asymmetry, or breast atrophy due to reasons such as breastfeeding. The success of the operation depends not only on the intraoperative operation, but also on postoperative care. Postoperative fixation and support of the chest have a profound impact on the stability of the prosthesis, wound healing, and the presentation of the final effect. Good postoperative care can reduce the occurrence of postoperative complications, such as prosthesis displacement, capsular contracture, hematoma, infection, etc., and at the same time help relieve postoperative pain and promote patient recovery.

[0003] At present, the commonly used fixation tools after breast prosthesis implantation mainly include ordinary elastic bandages, special postoperative bras, and some specially designed postoperative fixation belts. These tools can provide postoperative support and fixation to a certain extent, but there are still some problems that need to be solved. For example, patent document CN202323563197 proposes a chest fixation belt after breast prosthesis implantation, which fixes the prosthesis by setting a fixing belt and a support part in the middle of the body to prevent the prosthesis from shifting. However, the fixing belt and the support part adopt an overall pressure design, which cannot be adjusted according to the individual differences of the patient, resulting in uneven pressure distribution. This uneven pressure distribution may exert excessive pressure on key areas such as the lower edge of the breast and the armpit.

[0004] In view of the defects of the existing technology, there is an urgent need for a postoperative fixation device that is more stable, more flexible and more comfortable to meet the diverse needs of patients during postoperative recovery. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a chest fixation belt after breast prosthesis implantation, which can flexibly adjust the tightness of different areas according to the degree of postoperative swelling, individual body shape differences and changes in the recovery stage, so as to better adapt to the patient's physical characteristics and activity needs.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A chest fixing band after breast prosthesis implantation, comprising a fixing cushion layer; local tension adjusting mechanisms are arranged on both sides of the fixing cushion layer. The local tension adjusting mechanism includes a plurality of supporting cushion layers. A plurality of piston grooves are opened in both sides of the supporting cushion layer. A transfer groove is communicated between adjacent piston grooves, and an adsorption mechanism for fixing the supporting cushion layer on the patient's skin is communicated in each transfer groove. An adjusting mechanism for adjusting the negative pressure in the transfer groove is also arranged in the transfer groove; a connecting pipe is slidably connected in the piston groove, and the connecting pipe is used to communicate the piston grooves in adjacent supporting cushion layers with each other. One end of the connecting pipe far away from the transfer groove near the fixing cushion layer is communicated with a negative pressure mechanism for generating negative pressure. One end of the connecting pipe near the transfer groove is provided with a piston block, and the piston block is slidably matched with the piston groove. A communicating mechanism is arranged in each piston block, and the communicating mechanism is used to communicate the connecting pipe with the transfer groove when the negative pressure mechanism operates, and disconnect the connecting pipe from the transfer groove when the negative pressure mechanism does not operate.

[0008] The above scheme has the following beneficial effects:

[0009] Principle: When in use, the patient wraps the fixing cushion layer around the chest and starts the negative pressure mechanism to fix the supporting cushion layer on the patient's skin. The negative pressure generated by the negative pressure mechanism is transmitted to each transfer groove through the connecting pipe and finally acts on the adsorption mechanism to assist the supporting cushion layer to be adsorbed and fixed on the patient's skin. After the supporting cushion layer is fixed, the negative pressure mechanism is turned off. At this time, the connection between the connecting pipe and the transfer groove is interrupted, a stable negative pressure is formed in the transfer groove, and the adsorption mechanism is stably adsorbed on the patient's skin.

[0010] If it is necessary to adjust the tightness of a certain area, the negative pressure in the transfer groove can be adjusted through the adjusting mechanism, so as to change the length of the connecting pipe in the piston groove, or unlock the adsorption mechanism in this area to adjust the tightness of this area.

[0011] 1. Existing fixing bands usually have a unified size and are difficult to adapt to the body type differences of different patients and the swelling changes after surgery. Through the collaborative work of the adsorption mechanism and the adjusting mechanism, the present invention can be accurately adjusted according to the actual shape and size of the patient's chest to achieve personalized adaptation. Whether the patient is thin, overweight or has different degrees of postoperative swelling, the fixing cushion layer can closely fit the chest curve, provide a uniform and appropriate pressure distribution, and avoid discomfort and complications caused by being too tight or too loose.

[0012] 2. Due to the lack of a flexible adjustment mechanism, traditional fixing bands often bring a sense of compression and discomfort to patients during wearing, especially during long-term wearing or daily activities. The present invention significantly improves the comfort of patients by dispersing pressure, reducing local compression points and adapting to body activities.

[0013] Furthermore, the adsorption mechanism includes a first negative pressure pipeline and a suction cup; the suction cup is located inside the supporting cushion layer, and the suction cup is communicated with the transfer groove through the first negative pressure pipeline.

[0014] Beneficial effects: The suction cup is connected to the transfer tank through the first negative pressure pipeline. This design can ensure that the support cushion layer is tightly and stably adsorbed on the patient's skin. The generation of negative pressure makes the suction cup firmly adhere to the skin surface. Even when the patient is performing daily activities or body movements, the position of the fixing belt can be kept unchanged, thereby providing continuous and stable support and fixation effects for the chest.

[0015] Furthermore, the adjusting mechanism includes a second negative pressure pipeline; the second negative pressure pipeline connects the transfer tank with the outside. One side of the second negative pressure pipeline is connected with a sliding groove, and a separating block is slidably matched in the sliding groove. A spring is arranged between the separating block and the sliding groove; the end of the second negative pressure pipeline far from the transfer tank is slidably connected with a button. An air inlet pipeline is opened in the button, and the air inlet pipeline connects the second negative pressure pipeline with the outside. One end of the button close to the separating block is slidably matched with the separating block. When the button pushes the separating block back into the sliding groove, the air inlet channel is connected with the second negative pressure pipeline.

[0016] Beneficial effects: Medical staff or patients can control the movement of the separating block only by pressing the button, thereby realizing the connection or closing of the air inlet pipeline and the second negative pressure pipeline, and then adjusting the negative pressure in the transfer tank. This intuitive operation method does not require complex tools or skills and is convenient for frequent adjustment during postoperative care to meet the different needs of patients. The cooperation between the button and the separating block allows for fine adjustment of the negative pressure. By controlling the pressing force and time of the button, the amount of air entering the transfer tank can be precisely adjusted, thereby realizing flexible control of the negative pressure magnitude.

[0017] Furthermore, the negative pressure mechanism includes a main chamber opened in the fixed cushion layer; the main chamber is respectively connected with the outside and the connecting pipe, and a micro pump is arranged on the communication path between the main chamber and the outside.

[0018] Beneficial effects: The micro pump can precisely control the magnitude of the negative pressure in the main chamber, thereby ensuring that the adsorption forces of the support cushion layers connected by all the connecting pipes are uniform and stable. This precise control ability is crucial for postoperative care because different patients and different recovery stages may require different negative pressure levels to ensure that the fixing belt can provide sufficient support without causing discomfort or complications to the patients.

[0019] Furthermore, the connecting mechanism includes a right-angle channel; the piston grooves located on the same connecting path are arranged in parallel. When the piston block coincides with the transfer tank, both ends of the right-angle channel are respectively connected with the piston grooves; a magnetic block is arranged at one end of the piston groove close to the transfer tank, and the piston block is made of a magnetic material.

[0020] Beneficial effects: Initially, the piston block fits with the side wall of the piston groove under the adsorption of the magnetic block, and the right-angle channel and the transfer groove are in a connected state, ensuring that the negative pressure can be smoothly transmitted to the adsorption mechanism, so that the support cushion layer is tightly adsorbed on the patient's skin. When the support cushion layer is fixed, with the natural support and movement of the patient's limbs, the connecting tube tends to move outward, and the piston block moves toward the end away from the transfer groove, thereby causing the right-angle channel to be misaligned and disconnected from the transfer groove. This automatic disconnection mechanism does not require additional manual operation and simplifies the use process.

[0021] After the right-angle channel is disconnected from the transit tank, the negative pressure in the transit tank can be effectively maintained stable, avoiding the weakening or loss of adsorption due to the entry of external air. The stable negative pressure environment helps to maintain the close fit between the support cushion and the patient's skin, ensure the stable fixation of the prosthesis and the good healing of the wound, and reduce the risk of postoperative complications caused by unstable fixation.

[0022] Furthermore, at least one sensing cavity is provided on the inner side of the supporting cushion layer; a temperature-sensitive metal sheet is provided at the opening of the sensing cavity, and a spare channel is connected to one side of the sensing cavity, and the spare channel is used to connect the first negative pressure pipe with the outside world. A pull rope is provided in the communication path between the sensing cavity and the spare channel, and one end of the pull rope is fixedly connected to the temperature-sensitive metal sheet, and a baffle is provided at the other end of the pull rope, and the baffle is used to temporarily block the spare channel, and a retractable mechanism for retracting and releasing the baffle is provided at the other end of the baffle.

[0023] Beneficial effects: The temperature-sensitive metal sheet can sense the temperature of the skin in contact with it in real time. When the temperature of the local skin rises due to redness and swelling, the temperature-sensitive metal sheet deforms and arches into the sensing cavity. This change triggers the retracting mechanism to retract the baffle, switching the backup channel from a blocked state to a connected state. This intelligent response mechanism can automatically adapt to the skin temperature changes that may occur after surgery without manual intervention, improving the intelligent level of nursing.

[0024] After the backup channel is connected, the negative pressure in the suction cup in that area is neutralized by the external air pressure, thereby releasing the binding force in that area. This automatic adjustment mechanism can effectively alleviate the problem of excessive local pressure caused by skin redness and swelling, avoid excessive pressure on the red and swollen area, promote blood circulation in the red and swollen area, and help the inflammation subside and the skin recover.

[0025] By timely reducing the pressure on the red and swollen area, this design can effectively prevent skin damage caused by excessive local pressure, such as pressure sores and ulcers. At the same time, it reduces the risk of infection caused by prolonged skin pressure, reduces the probability of postoperative complications, and improves the safety and reliability of postoperative care.

[0026] Further, the retracting and extending mechanism includes a storage groove opened on one side of the standby channel. The storage groove is communicated with the standby channel, and an elastic rope is arranged in the storage groove. Both ends of the elastic rope are fixedly connected to the baffle and the inner wall of the storage groove respectively.

[0027] Beneficial effects: Both ends of the elastic rope are fixedly connected to the baffle and the inner wall of the storage groove respectively. This design enables the baffle to automatically retract and extend under the elastic action of the elastic rope. When the temperature-sensitive metal sheet arches due to temperature rise, the pulling rope drives the baffle to move, blocking the standby channel; when the temperature returns to normal and the temperature-sensitive metal sheet returns to its original state, the elastic rope automatically pulls the baffle back to block the standby channel again. This automatic retracting and extending function eliminates the need for manual intervention, simplifies the operation process, and improves the convenience and intelligence level of nursing.

[0028] Further, both the support cushion layer and the fixing cushion layer are made of medical silicone material.

[0029] Beneficial effects: The medical silicone material is soft in texture and has appropriate elasticity, which can closely fit the chest curve, providing comfortable support and fixation effects. This softness and elasticity enable the fixing belt to adapt well to patients with different body types and chest sizes, reducing the sense of compression and discomfort on the skin.

[0030] Further, shoulder straps are arranged on the fixing cushion layer.

[0031] Beneficial effects: The shoulder straps can provide additional fixing points for the chest fixing belt, enhancing the overall stability of the fixing belt. Through the restraint of the shoulder straps, it can prevent the fixing belt from shifting or loosening during the patient's activities, ensuring that the support cushion layer and the adsorption mechanism always closely fit the chest, providing stable support for the prosthesis, and contributing to the correct position maintenance of the prosthesis and the healing of the wound.

[0032] Further, magic tapes or hook-and-loop fasteners are arranged on the outermost support cushion layer.

[0033] Beneficial effects: The magic tapes or hook-and-loop fasteners can quickly and firmly fix the entire fixing cushion layer on the patient's chest, ensuring that the fixing belt will not shift or come loose during use. This convenient fixing method enables patients or medical staff to easily complete the wearing and adjustment of the fixing belt, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following is a further detailed description through specific embodiments:

[0049] The embodiment is basically as shown in the attached Figures 1 - 10 figures: A chest fixing band after breast prosthesis implantation includes a fixing cushion layer 1. In this embodiment, the fixing cushion layer 1 is made of medical silicone material, which has excellent biocompatibility and softness, can closely fit the chest curve, and provide comfortable and stable support for the chest. Preferably, two shoulder straps 4 are provided on the fixing cushion layer 1, and the shoulder straps 4 are detachably connected to the fixing cushion layer 1 through Velcro.

[0050] Local tension adjustment mechanisms are provided on both sides of the fixing cushion layer 1. The local tension adjustment mechanism includes a number of support cushion layers 2, and the support cushion layers 2 are also made of medical silicone material to ensure the safety and comfort of contact with the human skin. A number of piston grooves 201 are opened on both sides of the support cushion layer 2, and a transfer groove 203 is communicated between adjacent piston grooves 201, and an adsorption mechanism for fixing the support cushion layer 2 to the patient's skin is communicated in each transfer groove 203.

[0051] Specifically, as shown in the attached Figure 5 figures, the adsorption mechanism includes a first negative pressure pipeline 202 and a suction cup 5; the suction cup 5 is located inside the support cushion layer 2, and the suction cup 5 is communicated with the transfer groove 203 through the first negative pressure pipeline 202. The suction cup 5 is communicated with the transfer groove 203 through the first negative pressure pipeline 202. This design can enable the support cushion layer 2 to closely adsorb on the patient's skin and provide a stable fixing effect for the chest.

[0052] In addition, an adjustment mechanism for adjusting the negative pressure in the transfer groove 203 is provided in each transfer groove 203.

[0053] Specifically, as shown in the attachedFigure 5 and the attached Figure 9 As shown, the adjusting mechanism includes a second negative pressure pipeline 204. In this embodiment, the first negative pressure pipeline 202 and the second negative pressure pipeline 204 are on the same horizontal line; the second negative pressure pipeline 204 connects the transfer tank 203 with the outside. One side of the second negative pressure pipeline 204 is connected with a chute 206. A partition block 208 is slidably fitted in the chute 206. The shape of the partition block 208 is trapezoidal. A spring 207 is arranged between the top of the partition block 208 and the top wall of the chute 206. Both ends of the spring 207 are welded and fixed to the top of the chute 206 and the top of the partition block 208 respectively; Figure 5 On the right end of the second negative pressure pipeline 204 in the [description], a button 205 is slidably connected. The shape of the button 205 is "T" shaped which rotates 90° clockwise. The bottom of the "T" shaped button 205 is an inclined surface which just fits with the bottom of the partition block 208. An air inlet pipeline 209 is opened in the button 205. The air inlet pipeline 209 connects the second negative pressure pipeline 204 with the outside. The left end of the button 205 is slidably fitted with the bottom of the partition block 208. When the button 205 pushes the partition block 208 back into the chute 206, the air inlet channel is connected with the second negative pressure pipeline 204. At this time, the air inlet pipeline 209 is just exposed in the second negative pressure pipeline 204.

[0054] Combined with the attached Figure 4 and the attached Figure 5 and the attached Figure 6 As shown, a connecting pipe 3 is slidably connected in each piston groove 201. The connecting pipe 3 is used to connect the piston grooves 201 in adjacent support cushions 2 to each other, that is, all the support cushions 2 in this embodiment are connected in series through the connecting pipe 3. Preferably, in this embodiment, magic tapes are adhesively fixed on the outermost support cushions 2. Two support cushions 2 are detachably connected through male-female magic tapes.

[0055] One end of the connecting pipe 3 close to the fixed cushion 1 away from the transfer tank 203 (that is, Figure 6 the left end of the left connecting pipe 3 in the [description]) is connected with a negative pressure mechanism for generating negative pressure. Specifically, the negative pressure mechanism includes a main chamber 101 opened in the fixed cushion 1; the main chamber 101 is respectively connected with the outside and the connecting pipe 3. A micro pump 102 is installed on the communication path between the main chamber 101 and the outside. Through the precise control of the micro pump 102, it can ensure that the adsorption forces in the suction cups 5 on all the support cushions 2 connected by the connecting pipes 3 are uniform and stable.

[0056] Combined with the attached Figure 6 and the attached Figure 10As shown in the figure, piston blocks 301 are fixedly welded to one end of the connecting pipes 3 close to the transfer tank 203. The piston blocks 301 are slidably fitted with the piston grooves 201. A communication mechanism is provided in each piston block 301. The communication mechanism is used to connect the connecting pipe 3 with the transfer tank 203 when the negative pressure mechanism operates, and disconnect the connecting pipe 3 from the transfer tank 203 when the negative pressure mechanism does not operate.

[0057] Specifically, as shown in the attached Figure 10 figure, the communication mechanism includes a right-angle channel 302 opened in the piston block 301; the piston grooves 201 located on the same communication path are arranged in parallel, that is, the piston grooves 201 on the same communication path are not on the same straight line. When the piston block 301 coincides with the transfer tank 203, both ends of the right-angle channel 302 are respectively communicated with the piston grooves 201; a magnetic block 303 is embedded at one end of the piston groove 201 close to the transfer tank 203. The piston block 301 is made of a magnetic material. The magnetic block 303 can generate an attractive force to adsorb the piston block 301. In this embodiment, the magnetic field generated by the magnetic block 303 is weak, and the magnetic block 303 and the piston block 301 can be easily separated from each other.

[0058] Preferably, as shown in the attached Figure 5 figure and the attached Figure 8 figure, at least one induction cavity 212 is further provided inside the support cushion layer 2. In some other embodiments, the induction cavity 212 is circumferentially opened around the suction cup 5. Increasing the number of the induction cavities 212 and adjusting the layout position of the induction cavities 212 can increase the induction area and induction sensitivity; a temperature-sensitive metal sheet 211 is fixedly welded at the opening of the induction cavity 212. In this embodiment, the temperature-sensitive metal sheet 211 is a bimetallic sheet. In this embodiment, the bimetallic sheet is customized from two metals with different thermal expansion coefficients. It can generate deformation when the temperature reaches 37°C (generally, under normal circumstances, the temperature of the human skin is roughly between 36°C and 37°C (affected by the ambient temperature and individual differences)), that is, the center of the bimetallic sheet arches towards the inside of the induction cavity 212. One side of the induction cavity 212 is communicated with a standby channel 210. Both ends of the standby channel 210 are respectively communicated with the first negative pressure pipe 202 and the outside. A pull rope 213 is slidably fitted in the communication path between the induction cavity 212 and the standby channel 210. One end of the pull rope 213 is fixedly bonded to the temperature-sensitive metal sheet 211, and the other end of the pull rope 213 is fixedly bonded to a blocking piece 214. The blocking piece 214 is used to temporarily block the standby channel 210. A retracting and releasing mechanism for retracting and releasing the blocking piece 214 is provided at the other end of the blocking piece 214.

[0059] Specifically, as shown in the attached Figure 8 figure, the retracting and releasing mechanism includes a storage groove 216 opened on one side of the standby channel 210. The storage groove 216 is communicated with the standby channel 210. An elastic rope 215 is arranged in the storage groove 216. Both ends of the elastic rope 215 are respectively fixedly bonded to the blocking piece 214 and the inner wall of the storage groove 216.

[0060] The specific implementation process is as follows:

[0061] When in use by the patient, first wrap the fixing cushion layer 1 around the chest, start the micro pump 102, so that the supporting cushion layer 2 is adsorbed and fixed on the patient's skin through the suction cups 5. The negative pressure generated by the micro pump 102 is transmitted through the connecting pipe 3 to each transfer groove 203 (in the initial state, under the magnetic force generated by the magnetic block 303, the piston block 301 closely fits against the side wall of the piston groove 201. At this time, the right-angle channel 302 in the piston block 301 is in communication with the transfer groove 203. This communication state ensures that the negative pressure can be smoothly transmitted from the negative pressure mechanism to the adsorption mechanism), and finally acts on the adsorption mechanism (suction cups 5). The adsorption mechanism generates an adsorption force, enabling the supporting cushion layer 2 to be closely adsorbed on the patient's skin surface, thereby providing a stable support and fixing effect for the chest. At the same time, bond and bind the outermost supporting cushion layer 2 through Velcro, and then fix the shoulder strap 4 to the fixing cushion layer 1 through Velcro.

[0062] After the supporting cushion layer 2 is fixed, turn off the micro pump 102. At this time, the connection between the connecting pipe 3 and the transfer groove 203 is interrupted, and a stable negative pressure is formed in the transfer groove 203, and the adsorption mechanism is stably adsorbed on the patient's skin.

[0063] As the patient stretches the body, the connecting pipe 3 will be subjected to a certain external force and tend to move outward. This external force will drive the piston block 301 to slide in the piston groove 201, causing the piston block 301 to move towards the end away from the transfer groove 203. As the piston block 301 moves, the right-angle channel 302 and the transfer groove 203 are gradually misaligned, and finally the connection between the two is disconnected. At this time, a stable negative pressure space will be formed among the transfer groove 203, the first negative pressure channel 202, and the suction cups 5, automatically completing the final fixation of the suction cups 5, and at the same time preventing the continuous increase of the negative pressure in the suction cups 5 from causing discomfort to the patient's skin. This automatic disconnection mechanism does not require additional manual operations by medical staff or patients, greatly simplifies the use process, and improves the convenience and intelligence level of the device.

[0064] When the patient feels that a certain area of the body is relatively tight, it is necessary to determine the position of the corresponding supporting cushion layer 2 in this area. Locate the corresponding button 205 on the supporting cushion layer 2 in this area and gently press the button 205 with a finger. The bottom of the button 205 will push the isolation block 208 to move into the chute 206 against the elastic force of the spring 207. When the isolation block 208 is pushed into the chute 206, the air inlet pipe 209 is in communication with the second negative pressure pipe 204, and external air enters the transfer groove 203 to adjust the negative pressure in the transfer groove 203. By controlling the pressing force and time of the button 205, the amount of air entering the transfer groove 203 can be precisely adjusted, thereby realizing flexible control of the negative pressure magnitude and then changing the tightness of this area.

[0065] After reaching the appropriate tightness, release the button 205. Under the elastic force of the spring 207, the isolation block 208 resets, the intake pipe 209 is disconnected from the second negative pressure pipe 204, and a stable negative pressure is maintained in the transfer tank 203.

[0066] When a certain area becomes red and swollen during the daily activities of the patient, the skin temperature of that area will increase. The temperature-sensitive metal sheet 211 can sense the skin temperature in contact with it in real time. When the temperature rises to a certain level (for example, reaches 37 °C), the temperature-sensitive metal sheet 211 will deform and arch towards the inside of the induction cavity 212.

[0067] The deformation of the temperature-sensitive metal sheet 211 will cause the pull rope 213 fixedly connected to it to become loose. The other end of the pull rope 213 is connected to the baffle 214. As the pull rope 213 becomes loose, under the action of the elastic cord 215, the baffle 214 will move from the position originally blocking the spare channel 210 into the storage groove 216.

[0068] As the baffle 214 moves, the spare channel 210 originally blocked by the baffle 214 is opened. When the spare channel 210 is opened, the negative pressure in the suction cup 5 in that area will be neutralized by the external air pressure. This is because the external air can enter the inside of the suction cup 5 through the spare channel 210, making the pressure in the suction cup 5 balance with the external pressure, thereby releasing the binding force in that area and alleviating the problem of excessive local pressure caused by skin redness and swelling.

[0069] The above are only embodiments of the present invention, and common knowledge such as specific structures and / or characteristics known in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners in the specification can be used to explain the content of the claims.
