A chest belt for preventing nipple pressure after breast cancer prosthesis surgery

Abstract

This invention belongs to the field of breast band technology, specifically relating to a breast band to prevent nipple pressure after breast cancer implant surgery. The breast band includes a cup, straps, and shoulder straps. The cup includes an outer layer and an inner layer, connected to the straps and shoulder straps. The inner layer is connected to the inside of the outer layer. The breast band also includes a fluid circulation mechanism, comprising a fluid storage device, a main channel, and branch channels. The cup of this invention covers the outside of the reconstructed breast. When fluid is filled into the main channel and branch channels, a breast band network is formed, providing support and shaping for the breast. When fluid leaks out of the main channel and branch channels, the channels collapse, the pressure of the breast band network on the breast disappears, and the breast relaxes. Therefore, the pressure exerted by the breast band of this invention on the breast is intermittent, preventing prolonged pressure and achieving both shaping and comfort.

Description

Technical Field

[0001] The invention belongs to the technical field of chest belts, and in particular relates to a chest belt for preventing nipples from being compressed after breast cancer prosthesis surgery. Background Art

[0002] Breast cancer is a malignant tumor that occurs in women and seriously threatens women's lives and quality of life. Surgical resection is the main treatment for breast cancer, and most women have a strong demand for maintaining breast beauty. Therefore, most patients who choose modified radical mastectomy for breast cancer will choose breast reconstruction to reduce the pain caused by breast loss in breast cancer patients. Breast reconstruction plays an important role in improving postoperative quality of life and psychological satisfaction, and reducing psychological incompleteness. The development of breast reconstruction surgery has also become one of the surgical procedures that is widely valued by the whole society. At present, implant reconstruction surgery is mainly the posterior implantation of the pectoralis major muscle, which cuts and lifts the pectoralis major muscle and covers the implant with the pectoralis major muscle. Due to its destructive operation and structural changes to the pectoralis major muscle, pain and limb dysfunction are very obvious, and there are many complications; in addition, because the implant is fixed and pulled by the pectoralis major muscle, the breast shape is poorly symmetrical, and the incidence of capsular contracture is high, which cannot meet the needs of patients well.

[0003] Since the reconstructed breast is a prosthesis, the blood circulation is poor. If patients who have undergone breast reconstruction wear ordinary bras for a long time, it will compress the breasts and nipples, which can easily cause deformation of the breast appearance. On the other hand, long-term compression can also cause discomfort to patients. Therefore, it is necessary to develop a bra or chest strap that can reduce compression.

[0004] CN107536118A discloses a heating bra, comprising a bra body, two cups are arranged on the bra body, each cup is combined with a flexible heat-conductive film, and a heating component is combined with a partial position of each heat-conductive film. When a user wears the heating bra, the breasts are covered by the two heat-conductive films, and then the control device controls each heating component to heat a partial position of each heat-conductive film, which can quickly diffuse heat to the entire heat-conductive film and emit heat evenly, warm the user's breasts and enhance blood circulation therein, promote breast health, and improve the comfort of wearing the bra.

[0005] CN105455202A discloses a women's bra, wherein the lower half of the inner lining of the cup of the bra is provided with a butterfly-shaped massage belt, and a plurality of flexible balls are arranged in the massage belt. The bra achieves a massage effect while realizing the plastic effect of an ordinary bra, thereby enhancing the blood circulation of the chest and improving the comfort of wearing the bra.

[0006] The above-mentioned bras can promote blood circulation in the breasts and improve the comfort of wearing the bras. However, when wearing the bras, the cups are still tightly fitted to the breasts, and the pressure from the cups still exists. For breasts that have just undergone reconstruction surgery, there is still a risk of the appearance of the breasts being compressed and deformed, and the discomfort caused by the compression has not disappeared.

[0022] In order to reduce the pressure of the chest strap on the reconstructed breast / nipple, we set up a fluid circulation mechanism and a multi-layered cup. The cup includes an outer cover and an inner cover. The outer cover is used to wrap the entire breast to prevent the breast from rubbing and colliding with the outside world and protect the breast. The inner cover is about half the size of the breast and is used to lift the lower part of the breast. Due to the setting of the inner cover, there is a gap between the outer cover and the upper part of the breast, so the upper part of the breast can be in a relaxed state, avoiding the risk of compression and deformation of the breast appearance, reducing the pressure of the chest strap on the breast and improving comfort. Main pipes are set on the shoulder straps and the straps, and branch pipes are set between the outer cover and the inner cover. When the main pipe and the branch pipe are filled with fluid, they expand. The expanded multiple main pipes and branch pipes form a layer of bra network. At this time, the bra network has the main effect of lifting and shaping the breast, and the cup has an auxiliary shaping effect. When the fluid in the main pipe and the branch pipe is lost, the main pipe and the branch pipe are deflated, the pressure of the bra network on the breast disappears, and the breast is in a relaxed state. When the main pipe and the branch pipes are alternately filled or not filled with fluid, the chest belt of the present invention exerts intermittent pressure on the breasts, does not compress the breasts for a long time, and can achieve both shaping and comfort.

[0023] The present invention realizes the effect of alternately filling or not filling the pipeline with fluid through a liquid pumping switch.

[0024] In order to achieve the effect of automated control and provide greater convenience for the chest strap wearer, a controller is provided in this embodiment, to which a liquid extraction switch, a power supply, and a switch panel are respectively connected, and the controller is used to automatically control the flow of the fluid.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] Example 1

[0039] A breast brace to prevent nipple compression after breast cancer implant surgery, see Figure 1-2 , including cup 1, strap 2 and shoulder strap 3, cup 1 is fixed on strap 2, one end of shoulder strap 3 is cup 1, and the other end of shoulder strap 3 is connected to strap 2. Cup 1 is covered on the outside of the reconstructed breast to support and shape the breast, strap 2 connects two cups 1, shoulder strap 3 is worn on the shoulder, and the wearing method of shoulder strap 3, strap 2 and cup 1 is the same as that of an ordinary bra.

[0040] For example, the middle of the strap 2 is fixedly connected to two cups 1, one cup 1 is used to cover one breast, the two ends of the strap 2 are wrapped from the front side of the human body to the back side, and the two ends of the strap 2 are detachably connected at the back of the human body, for example, the two ends of the strap 2 are buckled by buckles. There are two shoulder straps 3, and one shoulder strap 3 is connected to one end of the strap 2 of one cup 1.

[0041] In order to reduce the pressure of the chest band on the reconstructed breast / nipple, we set up a fluid circulation mechanism and a multi-layered cup structure1. Figure 3-4 The cup 1 includes an outer cover 11 and an inner cover 12. The outer cover 11 is used to wrap the entire breast to prevent the breast from rubbing and colliding with the outside world and can protect the breast. The bottom of the outer cover 11 is fixedly connected to the strap 2, and the top of the outer cover 11 is fixedly connected to the corresponding shoulder strap 3. The area of ​​the inner cover 12 is 1 / 3-1 / 2 of the area of ​​the outer cover 11, so the inner cover 12 is about half the size of the breast. The inner cover 12 is connected to the inner side of the outer cover 11, for example, the bottom of the inner cover 12 is fixedly connected to the inner bottom of the outer cover 11, and the rest of the inner cover 12 is a free end. The inner cover 12 is used to pull up the lower half of the breast. Due to the setting of the inner cover 12, there is a gap between the outer cover 11 and the upper half of the breast, so the upper half of the breast can be in a relaxed state, avoiding the risk of the breast appearance being compressed and deformed, reducing the pressure of the chest strap on the breast and improving comfort.

[0042] The fluid circulation mechanism includes a fluid storage device 4, a main pipeline 41 and a branch pipeline 42. The fluid storage device 4 is arranged between the two shoulder straps 3. Preferably, when the chest strap is worn, the fluid storage device 4 is located on one side of the back of the human body, and the upper end of the shoulder strap 3 is put on the neck, and the fluid storage device 4 and the cup 1 are pulled up with the help of the strength of the neck. The main pipeline 41 is laid along the shoulder strap 3 and the strap 2. For example, the shoulder strap 3 and the strap 2 are designed as a hollow structure, and the main pipeline 41 is passed through the inside of the hollow structure to protect the main pipeline 41. There are multiple branch pipelines 42, and the branch pipelines 42 are arranged between the outer cover 11 and the inner cover 12, and one end of the branch pipeline 42 is connected to the main pipeline 41 in the strap 2, and the other end of the branch pipeline 42 is connected to the main pipeline 41 in the shoulder strap 3 on the same side. The fluid storage device 4 is respectively connected to the main pipelines 41 in the two shoulder straps 3, and the fluid storage device 4 is filled with a flowable fluid, such as water or liquid medicine. See the main pipeline 41 and the branch pipeline 42. Figure 2 Preferably, the branch pipes 42 are arranged to be distributed along the shape of the breast.

[0043] Exemplarily, the fluid storage device 4 is a storage bag or a flexible bag body, and the thickness of the fluid storage device 4 is 0.5-2 cm, that is, after the fluid storage device 4 is carried on the back of the human body, the back of the human body does not bulge much, and does not affect the appearance of the clothes.

[0044] Exemplarily, the shoulder strap 3 includes an upper strap 31 and a lower strap 32, and one end of the upper strap 31 is connected to the outer cover 11. The other end of the upper strap 31 is set 0-1 cm away from the first end of the tee 33. If the distance is 0, it means that the upper strap 31 is connected to the first end of the tee 33. The second end of the tee 33 is set 0-1 cm away from the upper strap 31 of another shoulder strap 3. If the distance is 0, it means that the upper strap 31 of another shoulder strap 3 is connected to the second end of the tee 33. The third end of the tee 33 is connected to the upper end of the fluid storage device 4, one end of the lower strap 32 is connected to the strap 2, and the other end of the lower strap 32 is set 0-1 cm away from the lower end of the fluid storage device 4. If the distance is 0, it means that the lower strap 32 is connected to the lower end of the fluid storage device 4. Correspondingly, the portion of the main pipeline 41 located on the shoulder strap 3 includes an upper end pipe 411 and a lower end pipe 412. The upper end pipe 411 is laid along the upper end belt 31, and the lower end pipe 412 is laid along the lower end belt 32. The first end and the second end of the tee 33 are respectively connected to the adjacent upper end pipe 411, and the fluid storage device 4 is respectively connected to the adjacent lower end pipe 412. This arrangement is convenient for laying the pipeline and also convenient for wearing the shoulder strap 3.

[0045] Connecting buckles 34 are correspondingly arranged on the two upper end straps 31 . After the connecting buckles 34 at different positions on the two upper end straps 31 are connected, the length of the shoulder strap 3 worn on the neck of a human body can be adjusted.

[0046] In order to achieve a better effect of avoiding compression, the main pipeline 41 and the branch pipeline 42 are both flexible pipelines. When filled with fluid, the main pipeline 41 and the branch pipeline 42 expand. Figure 3 The expanded multiple main pipes 41 and branch pipes 42 form a bra network, that is, a layer of mesh cover is added between the outer cover 11 and the inner cover 12. At this time, the bra network plays a major role in lifting and shaping the breasts, and the cup 1 plays an auxiliary role in shaping. When the fluid in the main pipe 41 and the branch pipe 42 is lost, the main pipe 41 and the branch pipe 42 are deflated, the pressure of the bra network on the breast disappears, and the breast is in a relaxed state. When the main pipe 41 and the branch pipe 42 are alternately filled or not filled with fluid, the pressure of the chest band of the present invention on the breast is intermittent, and the breast will not be compressed for a long time, so that both shaping and comfort can be achieved.

[0047] The present invention uses the liquid pumping switch 40 to achieve the effect of alternately filling or not filling the pipeline with fluid. Figure 3-6 , the fluid storage device 4 is provided with a liquid extraction switch 40 and a liquid filling port mechanism 43. Liquid is filled into the fluid storage device 4 through the liquid filling port mechanism 43, and the liquid filling port mechanism 43 is closed with a closing cover. The liquid extraction switch 40 is used to control the flow of fluid. When the liquid extraction switch 40 is turned on, the fluid flows from the main pipeline 41 and the branch pipeline 42 to the fluid storage device 4, and the main pipeline 41 and the branch pipeline 42 located at and near the breast are deflated, and the flowing fluid has a massage effect on the breast, avoiding the discomfort caused by long-term breast compression. The deflated main pipeline 41 and the branch pipeline 42 release some space, which can temporarily relax the breast and avoid compression. Preferably, the fluid flow direction is set to Figure 3 In the clockwise direction shown, the fluid moves from the bottom of the breast to the top of the breast. The force of the flow can lift the breast to prevent the breast from sagging, which has a good effect of protecting the shape of the breast. When the liquid extraction switch 40 is turned off, the fluid storage device 4 is higher than the position of the strap 2. The fluid storage device 4 automatically flows to the branch pipe 42 under the action of gravity, and the main pipe 41 and the branch pipe 42 located at and near the breast expand to form a layer of expanded bra network. At this time, the bra network plays a major role in lifting and shaping the breast.

[0048] Exemplarily, the liquid pumping switch 40 is a pump, and the liquid pumping switch 40 is connected to the third end of the tee 33, and the liquid pumping switch 40 is located between the third end of the tee 33 and the upper end of the fluid storage device 4. The size of the pump's liquid inlet is larger than the sum of the sizes of all the connecting ports of the lower end tube 412 at the lower end of the fluid storage device 4, so that the speed of water entering the fluid storage device 4 from the pump's liquid inlet is larger than the speed of water flowing out from the lower end of the fluid storage device 4. For example, the diameter of the pump's liquid inlet is larger than the sum of the diameters of the two connecting ports of the lower end tube 412 at the lower end of the fluid storage device 4. Since the speed of fluid entering the fluid storage device 4 from the pump's liquid inlet is larger than the speed of fluid flowing out from the lower end of the fluid storage device 4, when the pump is turned on, the fluid quickly enters the fluid storage device 4, and before it has time to flow away, the main pipeline 41 and the branch pipeline 42 near the breast and the breast can be deflated; when the pump is turned off, the fluid in the fluid storage device 4 gradually flows into and fills the main pipeline 41 and the branch pipeline 42 near the breast and the breast to expand. The liquid extraction switch 40 of this structure is easy to operate.

[0049] For example, see Figure 5-6 A structure of the filling port mechanism 43 is as follows: it includes a first opening 431, a first cover body 432 is provided at the first opening 431, and the first cover body 432 is the closing cover, and a flexible first liquid outlet pipe 433 is provided on the fluid storage device 4. Preferably, the first liquid outlet pipe 433 and the first opening 431 are located on the same surface of the fluid storage device 4. The function of the first opening 431 is to configure the fluid into the fluid storage device 4, and the first cover body 432 can cover the first opening 431. A sealing ring is provided between the first cover body 432 and the first opening 431. Preferably, a sealing ring is provided at the position of the first cover body 432 for contacting the edge of the first opening 431, so that after the first cover body 432 is covered at the first opening 431, there is no leakage. One end of the first liquid outlet pipe 433 is arranged on the surface of the fluid storage device 4 and is connected to the inside of the fluid storage device 4. The other end of the first liquid outlet pipe 433 is a movable end, and the movable end can extend into the first opening 431. After extending into the first opening 431, the first cover body 432 can cover the opening 431, and prevent the first opening 431 and the first liquid outlet pipe 433 from leaking to the outside of the fluid storage device 4, that is, after the first cover body 432 covers the opening 431, the first liquid outlet pipe 433 is cut off. The movable end of the first liquid outlet pipe 433 is used for the third end of the detachable tee 33. Exemplarily, the first liquid outlet pipe 433 is a flexible rubber tube or latex tube, which can be sleeved on the outside of the third end port of the tee 33, and after being sleeved, the third end of the tee 33 does not leak. The filling port mechanism 43 of this structure is simple to operate and simple in structure, which is convenient for flushing and connecting the tee 33 and the main pipeline 41.

[0050] For example, see Figure 7-8A structure of the filling port mechanism 43 is as follows: it includes a second opening 4301, a second movable cover 4302 is provided at the second opening 4301, and the second movable cover 4302 is the closing cover. A second liquid outlet pipe 4303 is provided on the fluid storage device 4, and the second liquid outlet pipe 4303 is rotatably connected to the fluid storage device 4, for example, the position where the second liquid outlet pipe 4303 is connected to the fluid storage device 4 is set as a bendable pipe 43031, and the bendable pipe 43031 is a corrugated pipe, a hose or other bendable pipe. The part of the second liquid outlet pipe 4303 that is not connected to the fluid storage device 4 is a hard pipe 43032, and the hard pipe 43032 is a hard plastic pipe or a stainless steel pipe. Preferably, the second liquid outlet pipe 4303 and the second opening 4301 are located on the same surface of the fluid storage device 4. The function of the second opening 4301 is to configure the fluid into the fluid storage device 4, and the second movable cover 4302 can cover the second opening 4301. A sealing component 4304 is provided on the inner side of the second movable cover 4302, and a channel 4305 is provided on the sealing component 4304. The hard tube 43032 of the second liquid outlet pipe 4303 can be embedded in the channel 4305, and after being embedded in the channel 4305, the channel 4305 seals the hard tube 43032, so that the hard tube 43032 cannot flow liquid.

[0051] Exemplarily, the inner surface of the second movable cover 4302 is provided with a sealing component 4304, and the sealing component 4304 is used to seal the second movable cover 4302 and the second opening 4301, and the portion of the sealing component 4304 used to contact the hard tube 43032 is provided with a channel 4305. Exemplarily, the channel 4305 is a groove with openings on three sides, and the hard tube 43032 can be embedded in the groove, or the channel 4305 is a tube with openings at both ends, and the hard tube 43032 can be inserted into the channel 4305. The surface of the sealing component 4304 is provided with a blocking component 4306 at a position below the channel 4305, and the blocking component 4306 is used to seal the tube mouth of the hard tube 43032. Preferably, the blocking component 4306 is located at the downstream edge of the channel 4305, and the downstream edge refers to the direction in which the fluid in the hard tube 43032 flows toward the fluid storage device 4. After the hard tube 43032 is inserted into the channel 4305, it is fixed and limited by the channel 4305, and the blocking component 4306 abuts against the tube mouth of the hard tube 43032, thereby sealing the hard tube 43032. In other words, when the second movable cover 4302 is opened, the hard tube 43032 can flow liquid, and when the second movable cover 4302 is closed, the hard tube 43032 cannot flow liquid.

[0052] It should be noted that, since the present invention also requires the operation of circulating fluid, the blocking component 4306 is configured to be deformable under the action of external force and to expose the tube opening of the hard tube 43032 to the outside. Figure 8As for the deformable block shown, when the fluid is not circulating, according to the principles of gravity and communicating vessels, most of the fluid exists in the main pipeline 41 of the binding band 2, the lower end band 32, and the branch pipeline 42 of the outer cover 11. However, the main pipeline 41 of the upper end band 31 and the tee 33 are located at a higher position, so the amount of fluid stored here is small. At this time, the liquid pressure on the hard tube 43032 is small, so the blocking component 4306 can still abut against the pipe mouth of the hard tube 43032 to seal the hard tube 43032. Only when the liquid extraction switch 40 is turned on to force the fluid to circulate, the liquid flow in the main pipeline 41 of the upper end band 31, the tee 33, and the hard tube 43032 increases, which generates pressure on the internal blocking component 4306 and causes it to deform. See FIG. Fig. 9 , the lower end of the hard tube 43032 is exposed. The advantage of setting such a blocking component 4306 is that when the liquid extraction switch 40 is not turned on, the liquid is retained in the main pipe 41 of the strap 2 and the lower end band 32 and the branch pipe 42 of the outer cover 11, and the main pipe 41 and the branch pipe 42 located at and near the breast expand to form a layer of expanded bra network, which has a shaping and lifting effect on the breast. It is prevented that the liquid flows into the fluid storage device 4 when the human body is moving.

The switch panel is a wireless switch panel, such as an infrared switch panel, and the switch panel can also be a wired switch panel. The switch panel is provided with an on key, an off key, a cycle key and an automatic working key. After pressing the on key, the power supply and the controller and other components are connected to the power supply, and the controller and the liquid extraction switch 40 are in a standby state. When the cycle key is pressed, the liquid extraction switch 40 works once, so that the fluid circulates once. After pressing the off key, both the controller and the liquid extraction switch 40 stop working.

[0055] The automatic working key is an automatic working mode, and a program is pre-written in the controller. When the automatic working key is pressed, the liquid pumping switch 40 automatically works intermittently, for example, after a period of time T1, the liquid pumping switch 40 works for a period of time T2. There is no need to manually control the fluid circulation, which is more convenient.
