Description

Technical Field

[0001] This invention relates to the field of pressure devices for use after neck dissection, and more specifically to a pressure-adjustable vest for use after neck dissection. Background Technology

[0002] Following neck lymph node dissection, the severance of lymphatic vessels and blood vessels can easily create cavities in the local tissue spaces, leading to the accumulation of lymphatic fluid, tissue fluid, or blood, and potentially causing complications such as seroma and infection. Continuous and uniform external pressure can ensure close adhesion between soft tissue and deeper structures, reducing dead space formation, promoting tissue healing, and limiting local fluid accumulation and swelling, thereby lowering the risk of complications and accelerating postoperative recovery.

[0003] Currently, the medical industry primarily uses compression vests for postoperative compression therapy. However, the pressure applied by traditional compression vests cannot be adjusted, making it difficult to dynamically adjust according to the actual needs of different rehabilitation stages such as the acute and recovery phases, which can easily affect the therapeutic effect. With technological advancements, adjustable pressure compression vests have emerged, but these vests still have the following drawbacks: factors such as pressure settings and patient body shape can cause the compression force to fail to be applied precisely and continuously to the target treatment area, leading to compression failure and affecting the reliability of the therapeutic effect and the patient's treatment experience. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a pressure-adjustable vest for use after neck dissection surgery. It adopts a combination of a chest and back fixation body, a first shoulder strap, a second shoulder strap, an airbag device, an air supply device, and an air extraction device. The air supply device and the air extraction device can be used to inflate and de-inflate the airbag to adjust the pressure intensity. Moreover, through the adjustment of the first shoulder strap, and with the help of elastic members and push members, the pressure of the airbag can be accurately and stably applied to the target treatment area to form effective pressure.

[0005] The objective of this invention is achieved through the following technical solution: An adjustable pressure vest for use after neck dissection includes a chest and back fixation body, a first shoulder strap, a second shoulder strap, an airbag device, an air supply device, and an air extraction device. The front and rear ends of the first shoulder strap are adjustablely connected to the chest and back fixation body via a first connector. The front and rear ends of the second shoulder strap are also connected to the chest and back fixation body. An airbag device is provided on the first shoulder strap. The airbag device includes an airbag pouch, an inflatable airbag, an elastic element, and a pushing element. The airbag pouch is disposed on the first shoulder strap, and a receiving cavity is formed on the airbag pouch. The inflatable airbag and the elastic element are located within the receiving cavity, with the inflatable airbag positioned below the elastic element. The elastic element includes a working part for pushing the inflatable airbag. The working part is adapted to move upward under the elastic force of the elastic element itself. The pushing element is used to push the working part downward against the elastic element. The air supply device supplies air to the inflatable airbag. The air extraction device extracts air from the inflatable airbag.

[0006] The front and rear ends of the second shoulder strap are detachably connected to the chest and back fixation body.

[0007] The front and rear ends of the second shoulder strap are both connected to the chest and back fixation body via the second connector.

[0008] The first connector is a first Velcro fastener.

[0009] The first shoulder strap and the second shoulder strap are adapted to be arranged in a cross configuration, and the intersection point of the first shoulder strap and the second shoulder strap is adapted to be connected by a cross connector.

[0010] The cross connector is a cross-connect Velcro.

[0011] The inflatable airbag is equipped with a first switching valve and a second switching valve.

[0012] The gas supply device includes a gas source and a first pipeline; the gas source is connected to the first pipeline, and the first pipeline is used to be detachably connected to a first switch valve; the gas extraction device includes a gas pump and a second pipeline, the gas pump is connected to the second pipeline, and the second pipeline is used to be detachably connected to a second switch valve.

[0013] A regulating valve is installed on the first pipeline.

[0014] The chest and back fixation device includes a fixing strap and a connecting strap; the connecting strap is connected to the fixing strap.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a pressure-adjustable vest for use after neck dissection surgery. It combines a chest-back fixation body, a first shoulder strap, a second shoulder strap, an airbag device, an air supply device, and an air extraction device. By inflating and deflating the airbag using the air supply and extraction devices, the pressure intensity can be flexibly adjusted to meet the pressure requirements of different rehabilitation stages, such as the acute and recovery phases. Furthermore, through adjustment of the first shoulder strap, and with the aid of elastic and pushing components, the airbag device is matched to the anatomical curve of the neck dissection area, precisely aligning and fitting with the target treatment area. This ensures that the pressure of the inflated airbag acts accurately and stably on the target treatment area, forming effective pressure and improving the reliability of the therapeutic effect. The pushing and elastic components allow for fine-tuning of the pressure intensity, improving both the reliability of the therapeutic effect and the patient's treatment experience.

Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-4As shown, a pressure-adjustable vest for use after neck dissection includes a chest and back fixation body 10, a first shoulder strap 20, a second shoulder strap 40, an airbag device 23, an air supply device 50, and an air extraction device 43. The front and rear ends of the first shoulder strap 20 are adjustablely connected to the chest and back fixation body 10 via a first connector 35, and the front and rear ends of the second shoulder strap 40 are also connected to the chest and back fixation body 10. An airbag device 23 is provided on the first shoulder strap 20. The airbag device 23 includes an airbag bag 30, an inflatable airbag 25, an elastic element 27, and a pushing element 24. A pouch 30 is disposed on the first shoulder strap 20, and a receiving cavity is formed on the pouch 30; the inflatable airbag 25 and the elastic member 27 are located in the receiving cavity, and the inflatable airbag 25 is disposed below the elastic member 27; the elastic member 27 includes an action part 28 for pushing the inflatable airbag 25; the action part 28 is adapted to move upward under the action of the elastic member 27's own elastic force, and the pushing member 24 is used to push the action part 28 downward against the elastic member 27; the air supply device 50 is used to supply air to the inflatable airbag 25; the air extraction device 43 is used to extract air from the inflatable airbag 25.

[0019] During the process of putting the pressure-adjustable vest on the patient, the front and rear ends of the first shoulder strap 20 can be adjusted so that the upper edge of the airbag device 23 is aligned 1 cm below the angle of the mandible, and the lower edge covers the supraclavicular fossa, directly facing the target treatment area (corresponding to the clavicle position), perfectly matching the anatomical curve of the lateral neck dissection area. After the pressure-adjustable vest is fixed on the patient through the chest and back fixation body 10, the first shoulder strap 20 and the second shoulder strap 40, the airbag 25 can be inflated and deflated using the air supply device 50 and the air extraction device 43 according to the pressure requirements of different rehabilitation stages such as the acute phase and the recovery phase, so that the airbag 25 can present different degrees of expansion to adjust the pressure intensity. At this time, the pushing member 24 can push the action part 28 downward by pressing against the elastic member 27, and the action part 28 pushes against the airbag 25 under the pushing action of the pushing member 24. In this way, the inflatable airbag 25 can apply pressure to the target treatment area through the airbag bag 30, effectively avoiding the problem in traditional designs where the airbag 25 has a small expansion range and thus leaves room for movement within the airbag bag 30, preventing the pressure of the airbag 25 from being effectively transmitted to the target treatment area and thus losing its pressurizing effect. Therefore, the present invention provides a pressure-adjustable vest for post-cervical dissection surgery, which adjusts the inflation volume of the airbag 25 through the air supply device 50 and the air extraction device 43, allowing for flexible control of the pressure intensity of the airbag 25 and achieving basic pressure adjustment to meet the treatment needs of different rehabilitation stages such as the acute and recovery phases after surgery. Furthermore, through the synergistic action of the adjustable first shoulder strap 20, the elastic element 27, and the pushing element 24, on the one hand, the adjustable first shoulder strap 20 allows for adjustment of the pressure position of the inflatable airbag 25 in the clavicle region, achieving precise alignment with the target treatment area; on the other hand, combined with the elastic element 27 and the pushing element 24, the action part 28 applies a conforming force to the inflatable airbag 25 under the upward rebound of the elastic element 27 and the pushing action of the pushing element 24, allowing the airbag device 23 to adapt to the complex curvature of the neck and conform to the target treatment area, ensuring that the pressure of the inflatable airbag 25 is accurately and stably applied to the target area to form effective pressure. Moreover, it also allows patients to fine-tune the pressure intensity in real time by adjusting the force of the pushing element 24 on the elastic element 27 according to their own feelings, significantly improving the reliability of the therapeutic effect and the patient's treatment experience.

[0020] The inflatable airbag 25 can be pre-shaped using a TPU film and has an arc-shaped air cavity with a curvature radius of 4cm. Of course, the inflatable airbag 25 can also be made of other materials and have other sizes and structures, but setting the inflatable airbag 25 to be pre-shaped using a TPU film and having an arc-shaped air cavity with a curvature radius of 4cm is the most preferred embodiment of the present invention. It can meet the corresponding inflation volume and, when used in conjunction with the air supply device 50 and the air extraction device 43, can support stepless dynamic pressure regulation of 0.02-0.1MPa.

[0021] The first connector 35 is a first Velcro strap. By placing the first Velcro strap at both the front and rear ends of the first shoulder strap 20, the user can easily adjust the position of the shoulder strap on the shoulder according to their own body shape, usage habits, etc., to ensure a good fit.

[0022] Specifically, the first Velcro includes a first male side and a first female side. Both the first male side and the first female side extend along the length direction L1 of the first shoulder strap 20. One of the first male side and the first female side of the first Velcro can be set on the first shoulder strap 20, and the other can be set on the chest and back fixation body 10. Thus, by bonding the first male side and the first female side at different positions along the length direction of the first shoulder strap 20, the connection length between the first shoulder strap 20 and the chest and back fixation body 10 can be quickly and steplessly adjusted. The operation is simple and can easily adapt to the chest size and body shape of different patients, ensuring that the vest is stable and fits well.

[0023] The front and rear ends of the second shoulder strap 40 are detachably connected to the chest and back fixation body 10. When the right shoulder strap is not needed, the second shoulder strap 40 can be detached from the chest and back fixation body 10 to flexibly adapt to different usage needs.

[0024] The front and rear ends of the second shoulder strap 40 are both connected to the chest and back fixation body 10 via a second connector 37. The second connector 37 can be a second Velcro fastener. Specifically, the second Velcro fastener includes a second male side and a second female side, both extending along the length L2 of the second shoulder strap 40. One of the second male side and the second female side can be located on the second shoulder strap 40, and the other on the chest and back fixation body 10. Separating the second male side and the second female side facilitates the removal of the second shoulder strap 40. Furthermore, the bonding of the second male side and the second female side at different positions along the length of the second shoulder strap 40 allows for rapid and stepless adjustment of the connection length between the second shoulder strap 40 and the chest and back fixation body 10. This simple operation easily adapts to different patients' chest circumferences and body shapes, ensuring the vest is stable and fits well.

[0025] The first shoulder strap 20 and the second shoulder strap 40 are adapted to be arranged in a cross configuration, and the intersection point of the first shoulder strap 20 and the second shoulder strap 40 is adapted to be connected by a cross connector 39. In use, the two shoulder straps can be crossed in an X-shape and connected at the intersection point, forming a stable mechanical structure that effectively prevents the vest from slipping or shifting during activity, significantly improving wearing stability and comfort. Furthermore, by adjusting the front and rear ends of the first shoulder strap 20 to the chest and back fixation body 10 via the first connector 35, and detachably connecting the front and rear ends of the second shoulder strap 40 to the chest and back fixation body 10, and by connecting the intersection point of the first shoulder strap 20 and the second shoulder strap 40 via the cross connector 39, the position or arrangement of the first shoulder strap 20 and the second shoulder strap 40 can be adjusted according to usage needs, improving the flexibility of use.

[0026] The cross connector 39 is a cross-connecting Velcro. By using cross-connecting Velcro for the cross connector 39, it is ensured that the "X" shaped structure can achieve the best fit and stability according to the user's shoulder width and back curve, and facilitates the connection and separation of the intersection of the first shoulder strap 20 and the second shoulder strap 40.

[0027] The inflatable airbag 25 is provided with a first switch valve 41 and a second switch valve 42. By opening the first switch valve 41, air can be added to the inflatable airbag 25, and by opening the second switch valve 42, air can be released from the inflatable airbag 25. The first switch valve 41 and the second switch valve 42 on the inflatable airbag 25 facilitate quick and independent control of the pressure state of the inflatable airbag 25, thereby improving the convenience of use.

[0028] The gas supply device 50 includes a gas source 51 and a first pipeline 52. The gas source 51 is connected to the first pipeline 52, which is detachably connected to a first switching valve 41. The air extraction device 43 includes a suction pump 44 and a second pipeline 45. The suction pump 44 is connected to the second pipeline 45, which is detachably connected to the second switching valve 42. In use, the first switching valve 41 is opened, and the gas supplied by the gas source 51 can be supplied to the inflatable airbag 25 through the first pipeline 52. When air extraction is required, the second switching valve 42 is opened, and the suction pump 44 operates, causing the gas in the inflatable airbag 25 to be pumped to the second pipeline 45. By using the gas supply device 50 and the air extraction device 43, inflation and extraction can be controlled independently and quickly, making pressure regulation more precise and convenient, facilitating maintenance, and reducing system complexity and cost.

[0029] A regulating valve 53 is installed on the first pipeline 52. The flow rate of the gas can be controlled by the regulating valve 53, which enables continuous and precise adjustment of the air pressure inside the inflatable airbag 25. This allows medical staff or patients to fine-tune the pressure according to the specific needs of different postoperative stages (such as the acute phase and the recovery phase) for precise pressurization.

[0030] The chest and back fixation device 10 includes a fixing strap 11 and a connecting strap 12; the connecting strap 12 is connected to the fixing strap 11. In use, the fixing strap 11 can cover the front and back areas, and the connecting strap 12 is used to fix the free end of the fixing strap 11 to the fixing strap 11, which makes it easy for users to quickly and conveniently put on and take off the fixing strap 11. At the same time, the connecting strap 12 can be adjusted according to the body shape to adjust the tightness and fit of the fixing strap 11, thereby improving the wearing experience.

[0031] Specifically, the fixing strap 11 is made of a 30% spandex and 70% cotton blend elastic fabric, which ensures wearing stability while further enhancing the wearing experience. The first shoulder strap 20 is provided with a insertion cavity, and the airbag 30 is detachably installed in the insertion cavity.

[0032] Specifically, the airbag 30 can be connected to the first shoulder strap 20 by means of zippers, Velcro, etc., so as to facilitate the removal and installation of the airbag 30.

[0033] A support plate 26 is also provided inside the accommodating cavity of the airbag 30. The pushing member 24 is an adjusting rod threaded onto the support plate 26. The end of the adjusting rod near the inflatable airbag 25 has an arc surface. When the inflation degree of the inflatable airbag 25 is small or when a slight increase in pressure is required, the adjusting rod can be turned clockwise to make the adjusting rod rotate downwards. The arc surface of the adjusting rod abuts against the elastic member 27 to push the action part 28 downwards. The action part 28 pushes the inflatable airbag 25, so that the inflatable airbag 25 is aligned and fits against the target treatment area. At this time, the pushing force of the action part 28 can be applied to the target treatment area through the inflatable airbag 25. Therefore, by controlling the downward rotation distance of the adjusting rod, the pressure can be finely adjusted. If a slight reduction in pressure is required, the adjustment lever is turned upwards using the reverse rotation knob. At this point, the upward rebound of the elastic element 27 causes the actuating part 28 to move upwards and press against the adjustment lever. This reduces the pressure exerted by the elastic element 27 on the inflatable airbag 25, thus slightly reducing the pressure intensity on the target treatment area. This structure allows patients to fine-tune the pressure intensity according to their own comfort, improving the treatment experience and facilitating fine-tuning. To further enhance ease of operation, several markings can be provided on the adjustment lever for users to refer to when rotating it, allowing for intuitive and precise control of the pressure adjustment range.

[0034] The elastic element 27 can be an elastic sheet made of silicone or elastic steel. The elastic sheet includes a diaphragm flap, which is arranged around the actuating part 28. The edge of the diaphragm flap is fixed to the bottom of the support plate 26 by a fixing ring 29. In use, the diaphragm flap can deform downward under the pushing force of the adjusting rod and rebound upward under its own elastic force, thereby driving the actuating part 28 to move.

[0035] Specifically, the airbag 30 includes a bag body and a flap. The flap is set on the bag body in an openable and closable manner. The bag body and the flap form the receiving cavity. The support plate 26 is fixed on the flap. The inflatable airbag 25 is placed in the bag body. The inflatable airbag 25 can be taken out and put in according to actual needs, further improving the convenience of use.

[0036] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
