Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an adjustable neck pressure bandage device. Background Art

[0002] The continuous development of modern medicine has led to an increasing variety of neck surgeries, such as surgery for thyroid malignancies, lymph node dissection for oral malignancies, and surgery for cervical lipomas. While these surgeries address the challenges of the disease, they also cause many problems for the patient's postoperative recovery. Among them, proper treatment of the surgical site after surgery is crucial to the rehabilitation process, and local pressure bandaging is a key link. The healing condition of the flap is directly related to the final outcome of the operation and the quality of the patient's rehabilitation. Appropriate pressure bandaging can effectively reduce interstitial fluid accumulation and promote local blood circulation, providing a strong guarantee for flap survival and healing.

[0003] At present, the conventional practice of neck compression bandage is to fix gauze on the compression part with the help of adhesive tape to achieve the compression function. However, this compression bandage method has many disadvantages.

[0004] For patients with chylous fistula who have undergone neck lymph node dissection, the structural morphology of the concave part of the supraclavicular fossa is relatively special, making it difficult for the tape to be tightly and firmly attached, making effective pressure application more difficult, and the tape frequently comes off, making the pressure application process unable to be continuous and stable. During the tape application process, the pressure control depends solely on experience and judgment, which is difficult to achieve accurate and uniform consistency, which not only weakens the actual effect of pressure application, but may also have an adverse effect on the healing process of the flap due to improper pressure.

[0005] When adhesive tape is in contact with the skin for a long time, it will leave a lot of adhesive marks that are difficult to remove, which has a very serious negative impact on the cleanliness and comfort of the patient's skin. At the same time, the material of the adhesive tape is prone to cause skin allergies. For people with sensitive skin, allergic reactions may aggravate local inflammation and even induce tension blisters, greatly increasing the patient's pain and the risk of infection.

[0006] The differences in physical characteristics of different patients also pose a severe challenge to the existing pressure bandage method. Obese patients have thick subcutaneous fat, unclear body surface landmarks, difficult gauze fixation, and the pressure position is prone to shift; male patients have well-developed sternocleidomastoid muscles, poor pressure transmission, and it is difficult to obtain the expected pressure effect at the venous angle; thin female patients have thin subcutaneous fat and muscles, and if the pressure is not applied properly, it may damage the cervical plexus or brachial plexus nerves and cause upper limb dysfunction.

[0007] In summary, the existing neck pressure bandage method has significant defects in effectiveness, stability, comfort and adaptability, and is in urgent need of improvement. Summary of the invention

[0008] The present invention aims to provide an adjustable neck pressure bandage device to solve the problems existing in the existing pressure bandage methods, to provide patients undergoing neck surgery with a safer, more effective, stable, comfortable and adaptable postoperative pressure bandage solution, to promote the smooth recovery of patients after surgery, and to improve the overall quality and effect of neck surgery treatment.

[0009] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an adjustable neck pressure bandage device, including a waist elastic belt and a No. 1 neck pressure belt, the ends of the waist elastic belt are detachably connected, one end of the No. 1 neck pressure belt is fixedly connected to the waist elastic belt, and the other end is passed around the shoulder and can be detachably connected to the waist elastic belt at the abdomen, the No. 1 neck pressure belt is provided with a No. 1 pressure part on the side close to the body, the No. 1 pressure part includes a pressure bag and an air bag, the pressure bag is fixedly connected to the No. 1 neck pressure belt, the air bag is placed in the pressure bag, and the pressure of the air bag can be adjusted.

[0010] The beneficial effects of this solution are: compared with the prior art, this technical solution has the following advantages: (1) Accurate positioning and effective pressure application: When in actual use, first wrap the waist elastic belt around the patient's waist and connect the two ends to fix it. Then place the airbag into the pressure bag, pass the No. 1 neck pressure belt from the patient's back to the shoulder, carefully adjust its position with the airbag to ensure that the airbag is accurately pressed on the part that needs pressure, and finally firmly fix the No. 1 neck pressure belt on the abdomen. This design greatly improves the accuracy of the pressure position, and successfully overcomes the problems of difficult attachment, easy loosening and unstable pressure caused by the special structure of the supraclavicular fossa of traditional tape, ensuring continuous, stable, accurate and effective pressure application, creating excellent conditions for flap healing, and enhancing the effectiveness of pressure application. At the same time, it reduces the waste of consumables caused by repeated replacement of dressings due to improper pressure application, and improves the work efficiency of medical staff.

[0011] (2) Precise pressure control: The airbag pressure can be adjusted as needed based on multiple factors such as the type of surgery and physical condition of the patient. Medical staff can set it accurately based on this, avoiding the inaccurate pressure control of traditional tape based on experience, so that the pressurized pressure can not only effectively prevent bleeding from the neck wound, reduce the surrounding tissue cavity to promote flap healing, but also prevent the adverse effects on the patient due to improper pressure, effectively ensuring the effectiveness and safety of pressurization, and helping patients recover after surgery. In addition, adjustable pressure can avoid excessive pressure causing breathing difficulties, or damage to the cervical plexus and brachial plexus nerves, causing numbness of the upper arm, movement disorders and other discomforts.

[0012] (3) Good stability: The ingenious connection structure of the waist elastic belt and the No. 1 neck compression belt forms a stable surrounding structure, which significantly enhances the stability of the device on the patient's body. Compared with the traditional tape that is easy to loosen, this structure effectively prevents the pressure position from shifting or the device from falling off during the patient's daily activities or body movement, ensuring that the pressure process is continuous and stable, which is conducive to the healing of the flap in a stable pressure environment and reduces the risk of poor healing due to unstable pressure.

[0013] (4) Improved comfort: This technical solution can effectively eliminate the serious negative impact of residual adhesive marks on skin cleanliness and comfort after long-term adhesion of the tape through the ingenious setting of the No. 1 pressure-applying part. Patients experience more comfort when wearing it after surgery, reducing the extra pain caused by the pressure bandage, which is conducive to maintaining a good psychological state and promoting recovery. At the same time, this design avoids tension blisters that may be caused by poor contact between the skin and the tape material from the root, significantly improving the patient's comfort and satisfaction. Compared with the vest-type pressure bandage method, the combination of the waist elastic belt and the No. 1 neck pressure belt adopted in this solution performs better in terms of breathability, can adapt well to the climate characteristics of each season, and has the advantage of being easy to wear.

[0014] (5) Wide adaptability: The device structure is designed to properly fit patients of different body types. The thick waist of obese patients can be accommodated by the elastic waist band and adjustable connection method, and the No. 1 neck pressure band can also be stabilized by adjusting the position; male patients with well-developed sternocleidomastoid muscles can also be effectively pressurized through reasonable layout; thin female patients can be accurately pressurized while avoiding nerve damage. This wide adaptability breaks through the limitations of traditional pressure bandages for patients of different body types, improves the applicability of the device in various patient groups, and facilitates its promotion and application in postoperative pressure bandage treatment for patients undergoing various neck surgeries, such as thyroid malignant tumor surgery, oral malignant tumor lymph node dissection, and neck lipoma surgery.

[0015] (6) The neck pressure bandage device provided by this technical solution is highly practical and low-cost. As a disposable product, it meets the infection management requirements and is made of soft material, which further improves the comfort of patients.

[0016] Furthermore, the airbag includes an airbag body and a pressing bag. A No. 1 one-way valve and a pressure relief valve are installed on the airbag body. The pressure relief valve is used to discharge the gas inside the airbag body. The outlet of the No. 1 one-way valve is connected to the inside of the airbag body through a pipe, and its air inlet is connected to one end of the pressing bag through a pipe. A No. 2 one-way valve is installed on the other end of the pressing bag.

[0017] The beneficial effects of this solution are as follows: when the airbag body needs to be inflated, the pressing bag is squeezed, and the air in the pressing bag is compressed. Due to the pressure change, the No. 1 one-way valve is opened, and the air in the pressing bag enters the airbag body through the No. 1 one-way valve, thereby gradually expanding the airbag body. When the pressing bag is released, due to the pressure difference between the pressing bag and the external environment, the No. 2 one-way valve opens, and the external air enters the pressing bag, causing the pressing bag to expand again. In this way, the pressing bag can continue to be squeezed to continuously inflate the airbag body.

[0018] When deflation is needed, the air in the airbag body can be released smoothly by simply pressing the pressure relief valve. This ingenious design makes the airbag more convenient to inflate and deflate, and the user can effectively control it, greatly improving the convenience and flexibility of using the airbag.

[0019] Furthermore, the airbag body is elliptical in shape, and three interconnected chambers are arranged inside the airbag body.

[0020] The beneficial effect of this solution is that the airbag body is designed to be elliptical and its interior is divided into three chambers, so that the airbag body can better fit the anatomical shape of the human neck. In actual use, this design can accurately fit the physiological curve of the human neck, especially more effectively exert pressure on the concave part of the supraclavicular fossa.

[0021] Furthermore, the first pressurizing unit also includes a condensation bag, which is placed inside the pressurizing bag.

[0022] The beneficial effect of this solution is that due to the setting of the condensation bag, when there is a need to apply cold compress to the patient's pressurized area during clinical treatment, the condensation bag can be simply placed in the pressurized bag to easily implement the cold compress operation on the pressurized area. This design provides more possibilities and convenience for clinical treatment. For example, in some cases where swelling and pain may occur after surgery, cold compress can effectively reduce local congestion and relieve pain, further improving the patient's comfort and treatment effect, and also expanding the application scope of the device in different treatment scenarios.

[0023] Furthermore, a sponge lining is fixedly connected to the inside of the pressurized bag on a side close to the body, the sponge lining is tightly fitted to the pressurized bag, and the condensation bag is located between the sponge lining and the airbag.

[0024] The beneficial effects of this solution are as follows: In this technical solution, when clinical treatment requires cold compress on the patient's pressurized area, the condensation bag is placed between the sponge lining and the airbag. On the one hand, the airbag can exert a compacting effect on the condensation bag, and this pressure makes the condensation bag less likely to shift during use and remain stable. On the other hand, the irregular texture on the surface of the sponge lining increases the friction between it and the condensation bag (this technical solution uses a sponge lining with a relatively rough surface). The two work together to effectively overcome the shaking and displacement problems that may occur in the condensation bag during use, greatly improve the stability of the condensation bag, and ensure the continuity and uniformity of the cold compress effect.

[0025] During the cold compress process, the sponge lining plays an important protective role. It can effectively prevent the patient's local skin from being frostbitten due to the low temperature of the condensation bag. Its existence makes the cold compress process safer and avoids additional damage to the patient due to improper cold compress. At the same time, the cushioning properties of the sponge lining also improve the patient's comfort during the cold compress and reduce the discomfort caused by the condensation bag.

[0026] Furthermore, an adjustment unit No. 1 is provided on the No. 1 neck pressure belt, and the adjustment unit No. 1 includes a clamping block, and the clamping block includes a first clamping block and a second clamping block, and the first clamping block and the second clamping block are both conical, and the large diameter end of the first clamping block is rotatably connected to the large diameter end of the second clamping block, and the small diameter end of the first clamping block and the small diameter end of the second clamping block are both fixedly connected to the limiting block, and a connecting rod is rotatably provided on the first clamping block, and the connecting rod can fix the No. 1 neck pressure belt.

[0027] The beneficial effect of this solution is: since the No. 1 neck compression belt is sewn to the waist elastic belt, when pressure needs to be applied to the other side of the patient's neck, the stretching amount on both sides of the No. 1 neck compression belt will be inconsistent. This uneven stretching amount will not only seriously damage the uniformity and stability of the neck compression, but will also have an extremely adverse effect on the patient's wearing comfort, greatly reducing the product's use effect and user experience. To address this problem, this technical solution innovatively introduces a No. 1 adjustment unit on the No. 1 neck compression belt.

[0028] When the stretching amount of the No. 1 neck pressure belt on both sides is different, first open the first clamping block and the second clamping block, and clamp the No. 1 neck pressure belt between the first clamping block and the second clamping block. At this time, it is necessary to ensure that the small diameter ends of the first clamping block and the second clamping block are accurately located on the side with relatively large elongation, while the large diameter ends of the first clamping block and the second clamping block are correspondingly located on the side with small elongation. Through this targeted layout arrangement, the conical structural characteristics of the clamping block are fully utilized to lay the foundation for the subsequent stretching amount adjustment. Then, rotate the connecting rod to the side away from the first clamping block to make enough space and flexibility for the rotation operation of the clamping block. Subsequently, rotate the clamping block so that the No. 1 neck pressure belt can be wound on the clamping block in an orderly manner. During this winding process, due to the structural characteristics of the clamping block and its close contact and interaction with the No. 1 neck pressure belt, the actual effective length of both sides can be effectively changed, thereby gradually realizing the precise adjustment of the stretching amount until the stretching amount on both sides tends to be consistent. Finally, after the stretching amount is adjusted, the connecting rod is stably rotated toward the side close to the first clamping block, and the No. 1 neck compression belt is fixed through the connecting rod. This ensures that the No. 1 neck compression belt can always remain stable during subsequent use, and continue to provide patients with a uniform, comfortable and efficient neck compression effect.

[0029] Furthermore, a No. 2 neck pressure belt is detachably connected to the No. 1 neck pressure belt, and a No. 2 neck pressure belt is provided with a No. 2 pressure part on the side close to the body, and the structure of the No. 2 pressure part is the same as that of the No. 1 pressure part.

[0030] The beneficial effects of this solution are as follows: Since the No. 2 neck pressure belt and the No. 1 neck pressure belt are detachably connected, the No. 2 neck pressure belt is provided with a No. 2 pressure part on the side close to the body, and the structure of the No. 2 pressure part is the same as that of the No. 1 pressure part. When it is necessary to apply pressure to the left and right sides of the patient, medical staff can easily connect the No. 2 neck pressure belt with the No. 1 neck pressure belt, so that the No. 2 pressure part can apply pressure to the depression of the supraclavicular fossa on the other side of the patient. This design breaks through the limitations of traditional unilateral pressure devices, provides a comprehensive and effective pressure treatment plan for patients with bilateral pressure bandages, and greatly improves the applicability and treatment range of the device; in addition, it is convenient for medical operation and clinical application, and the detachable connection is easy to install and adjust, which can save time and improve efficiency in complex scenarios, and the standardized design reduces the learning cost and operation difficulty, which is conducive to wide application and promotion.

[0031] Furthermore, the No. 2 neck compression belt is connected to the No. 1 neck compression belt via Velcro.

[0032] The beneficial effect of this solution is that: since the No. 2 neck pressure belt is connected to the No. 1 neck pressure belt by Velcro, the No. 2 neck pressure belt can be easily disassembled and connected.

[0033] Furthermore, a plurality of buttons are sewn in a matrix arrangement on one side of the No. 1 neck pressure belt away from the waist elastic belt, and a plurality of buckles are arranged on both sides of the lower end of the No. 2 neck pressure belt.

[0034] The beneficial effects of this solution are as follows: Due to the arrangement of the buckles and buttons, this technical solution can connect the No. 2 neck compression belt to the No. 1 neck compression belt through the cooperation between the buckles and buttons, thereby realizing the combined use of the two; at the same time, multiple buckles are designed on both sides of the No. 2 neck compression belt. When it is found that the stretching amount on both sides is different, the buckles at different positions can be connected and fixed with the corresponding buttons to change the actual effective length of both sides, so as to realize the precise adjustment of the stretching amount until the stretching amount on both sides tends to be consistent. In this way, the No. 2 neck compression belt can provide uniform and stable pressure to the patient's neck, significantly enhancing the patient's wearing comfort.

[0035] Furthermore, a pull ring is fixedly connected to the airbag body, a connecting block is fixedly connected to the waist elastic belt, a connecting channel is formed between the connecting block and the waist elastic belt, an adjustment port is provided at a position close to the opening end of the pressurization bag on the No. 1 neck pressure belt, a No. 2 adjustment unit is provided on the No. 1 neck pressure belt, and the No. 2 adjustment unit includes a Japanese-shaped buckle. The No. 1 neck pressure belt passes through the Japanese-shaped buckle and the connecting channel in sequence, and then is wrapped around the middle horizontal bar on the back of the Japanese-shaped buckle, and is sewn to the No. 1 neck pressure belt.

[0036] The beneficial effects of this solution are as follows: when wearing the No. 1 neck compression belt, first place the pull ring in the compression bag with the open end facing the compression bag, then slide the Japanese-shaped buckle downward on the No. 1 neck compression belt to adjust the effective length of the No. 1 neck compression belt to the maximum value, so that the patient can pass his arms through the No. 1 neck compression belt; then, fix the waist elastic belt at the patient's waist position to achieve preliminary overall wearing positioning and basic fixation; finally, slide the Japanese-shaped buckle upward in the opposite direction, and adjust the length of the No. 1 neck compression belt to the most appropriate state according to the patient's individual physical characteristics and actual wearing comfort requirements, to ensure that the entire wearing process is both convenient and efficient and can fit the patient's physical condition to the greatest extent.

[0037] When the position of the airbag needs to be adjusted, first slide the Japanese-shaped buckle downwards, and the effective length of the No. 1 neck pressure belt will increase, thus freeing up enough space and margin for subsequent operations. At this time, the hand can easily reach into the pressure bag through the adjustment port pre-set on the No. 1 neck pressure belt, and grab the pull ring to flexibly and accurately adjust the position of the airbag. When the position of the airbag is successfully adjusted to the ideal state, slide the Japanese-shaped buckle upwards again to adjust the length of the No. 1 neck pressure belt back to the appropriate position to ensure that the entire device can remain stable, comfortable and efficient after the airbag position is adjusted.

[0040] Example 1 like Figure 1 The adjustable neck compression bandage device shown comprises a waist elastic belt 1 and a No. 1 neck compression belt 2.

[0041] like Figure 1As shown, the waist elastic belt 1 is provided with a plurality of ventilation holes, which are conducive to the air flow between the waist elastic belt 1 and the patient's waist, thereby improving the comfort of the patient wearing it for a long time. A No. 1 Velcro patch 3 is sewn on the front side of the left end of the waist elastic belt 1, and a No. 1 Velcro patch 4 is sewn on the right end of the rear side of the waist elastic belt 1. Through the cooperation of the No. 1 Velcro patch 3 and the No. 1 Velcro patch 4, the waist elastic belt 1 can be fixed on the patient's waist.

[0042] like Figure 1 and Figure 2 As shown, the lower end of the No. 1 neck pressure belt 2 is sewn to the rear side of the waist elastic belt 1, and the front side of the No. 1 neck pressure belt 2 is provided with a No. 1 pressure part, which includes a pressure bag 5, which is sewn to the front side of the No. 1 neck pressure belt 2, and the lower side of the pressure bag 5 is an open end. An air bag is placed in the pressure bag 5, and the position of the air bag in the pressure bag 5 can be adjusted according to actual needs. A No. 2 Velcro patch 6 is sewn to the front side of the upper end of the No. 1 neck pressure belt 2. After the No. 1 neck pressure belt 2 is wrapped around the shoulders from the patient's back, it is matched and connected with the No. 1 Velcro patch 4 equipped with the waist elastic belt 1 set on the patient's abdomen.

[0043] like Figure 3 As shown, the airbag includes an airbag body 7, which is oval and has three interconnected chambers inside. This design can make the airbag body 7 adapt to the anatomical shape of the human neck. In actual use, this design can accurately fit the physiological curve of the human neck, especially can more effectively apply pressure to the depression of the supraclavicular fossa. A pressure relief valve 8 and a No. 1 one-way valve 9 are installed on the front side of the airbag body 7, wherein the pressure relief valve 8 is used to discharge the gas inside the airbag body 7. The No. 1 one-way valve 9 is located on the lower left side of the pressure relief valve 8. On the surface of the airbag body 7, a pressing bag 10 is fixed by gluing, and the pressing bag 10 is located on the right side of the No. 1 one-way valve 9. The air outlet of the No. 1 one-way valve 9 is connected to the inside of the airbag body 7 through a pipeline, and its air inlet is connected to the left side of the pressing bag 10 through a pipeline. A No. 2 one-way valve 11 is installed on the right side of the pressing bag 10. In order to improve the comfort of patients when using the device and take into account the aesthetics, the surfaces of the airbag body 7, the pressing bag 10 and the No. 1 one-way valve 9 are covered with breathable cotton cloth, so that the airbag body 7, the pressing bag 10 and the No. 1 one-way valve 9 form a whole.

[0044] When the airbag body 7 needs to be inflated, the pressing bag 10 is squeezed, and the air in the pressing bag 10 is compressed. Due to the pressure change, the No. 1 check valve 9 is opened, and the air in the pressing bag 10 enters the airbag body 7 through the No. 1 check valve 9, so that the airbag body 7 gradually expands. When the pressing bag 10 is released, due to the pressure difference between the pressing bag 10 and the external environment, the No. 2 check valve 11 is opened, and the external air can enter the pressing bag 10, so that the pressing bag 10 expands again. In this way, the pressing bag 10 can continue to be squeezed to continuously inflate the airbag body 7.

[0045] When deflation is required, the air in the airbag body 7 can be smoothly released by simply pressing the pressure relief valve 8. This design makes the inflation and deflation operations of the airbag more convenient and controllable.

[0046] The specific implementation process is as follows: In actual use, the waist elastic belt 1 is firstly wrapped around the patient's waist, and then the waist elastic belt 1 is fixed to the patient's waist by using the No. 1 Velcro patch 3 and the No. 1 Velcro patch 4. Next, the airbag is placed in the pressurized bag 5, and then the No. 1 neck pressurized belt 2 is passed around the patient's back and shoulders, and the positions of the No. 1 neck pressurized belt 2 and the airbag are adjusted to ensure that the airbag can be accurately pressed on the depression of the patient's supraclavicular fossa. Finally, the No. 1 neck pressurized belt 2 is firmly fixed to the waist elastic belt 1 on the patient's abdomen through the mutual cooperation of the No. 2 Velcro patch 6 and the No. 1 Velcro patch 4, so as to achieve effective pressing of the patient's required pressurized part.

[0047] Example 2 On the basis of Example 1, Figure 4 As shown, the No. 1 pressurizing part also includes a condensation bag, which is placed inside the pressurizing bag 5. A sponge lining 12 is sewn on the front side of the pressurizing bag 5. The sponge lining 12 fits tightly with the front side of the pressurizing bag 5, and the condensation bag is located between the sponge lining 12 and the airbag. When clinical treatment requires cold compress on the pressurized part of the patient, the condensation bag is placed between the sponge lining 12 and the airbag. On the one hand, the condensation bag can be pressed by the airbag, so that the condensation bag is not easy to shift during use and remains stable. On the other hand, the irregular texture on the surface of the sponge lining 12 increases the friction between it and the condensation bag (the present technical solution adopts a sponge lining 12 with a relatively rough surface). The two work together to effectively overcome the shaking and displacement problems that may occur in the condensation bag during use, greatly improve the stability of the condensation bag, and ensure the continuity and uniformity of the cold compress effect.

[0048] During the cold compress process, the sponge lining 12 plays an important protective role. It can effectively prevent the occurrence of frostbite on the patient's local skin due to the low temperature of the condensation bag. Its existence makes the cold compress process safer and avoids additional damage to the patient caused by improper cold compress. At the same time, the cushioning properties of the sponge lining 12 also improve the patient's comfort during the cold compress and reduce the discomfort caused by the condensation bag.

[0049] Example 3 On the basis of Example 1 or Example 2, Figure 5 As shown, the No. 1 neck compression belt 2 is provided with a No. 1 adjustment unit. Since the No. 1 neck compression belt 2 is sewn to the waist elastic belt 1, when the patient's neck on the right side needs to be compressed, the stretching amount on both sides of the No. 1 neck compression belt 2 will be inconsistent. This imbalance in stretching will not only seriously damage the uniformity and stability of the neck compression, but will also have an extremely adverse effect on the patient's wearing comfort, greatly reducing the product's use effect and user experience. In response to this problem, the technical solution innovatively introduces a No. 1 adjustment unit on the No. 1 neck compression belt 2.

[0050] like Figure 6 As shown, the No. 1 adjustment unit includes a clamping block 14, and the clamping block 14 includes a first clamping block 15, a second clamping block 16 and a hinge 17. The left ends of the first clamping block 15 and the second clamping block 16 are connected by the hinge 17. The first clamping block 15 and the second clamping block 16 are both tapered, and the small-diameter ends thereof are both integrally formed with a limit block 28. By arranging the limit block 28 at the small-diameter ends of the first clamping block 15 and the second clamping block 16, the No. 1 neck pressure belt 2 wound on the clamping block 14 can be prevented from falling off, thereby improving the stability of the No. 1 neck pressure belt 2. The first clamping block 15 is located at the rear side of the second clamping block 16, and a connecting rod 20 is rotatably arranged on the first clamping block 15, and the connecting rod 20 can fix the No. 1 neck pressure belt 2. Specifically, two fixing blocks 18 are glued and fixed to the left end of the upper side of the first clamping block 15, a rotating shaft 19 is rotatably arranged between the two fixing blocks 18, a connecting rod 20 is fixed to the rotating shaft 19 by gluing, and an insertion rod 21 is fixed to the right end of the lower side of the connecting rod 20 by gluing, and a hole is opened at a corresponding position on the limit block 28 of the second clamping block 16, and the insertion rod 21 can be engaged with the hole to fix the No. 1 neck pressure belt 2.

[0051] When the stretching amount of the two sides of the No. 1 neck pressure belt 2 is different, first open the first clamping block 15 and the second clamping block 16, and clamp the No. 1 neck pressure belt 2 between the first clamping block 15 and the second clamping block 16. At this time, it is necessary to ensure that the small diameter ends of the first clamping block 15 and the second clamping block 16 are accurately located on the side with relatively large stretching amount, and the large diameter ends of the first clamping block 15 and the second clamping block 16 are correspondingly located on the side with small stretching amount. Through this targeted layout arrangement, the conical structural characteristics of the clamping block 14 are fully utilized to lay the foundation for the subsequent stretching amount adjustment. Then, rotate the connecting rod 20 to the side away from the limit block 28 to make enough space and flexibility for the rotation operation of the clamping block 14. Subsequently, the clamping block 14 is rotated so that the No. 1 neck compression belt 2 can be wound on the clamping block 14 in an orderly manner. During this winding process, due to the structural characteristics of the clamping block 14 and its close contact and interaction with the No. 1 neck compression belt 2, the actual effective lengths on both sides can be effectively changed, thereby gradually achieving precise adjustment of the stretching amount until the stretching amounts on both sides tend to be consistent. Finally, after the stretching amount is adjusted, the connecting rod 20 is stably rotated toward the side close to the limit block 28 so that the insertion rod 21 can be clamped in the socket, thereby firmly fixing the No. 1 neck compression belt 2 on the clamping block 14, ensuring that in the subsequent use process, the No. 1 neck compression belt 2 can always remain in a stable state, and continue to provide patients with a uniform, comfortable and efficient neck compression effect.

[0052] Example 4 On the basis of Examples 1-3, Figure 7 As shown, the No. 1 neck pressure belt 2 is detachably connected to the No. 2 neck pressure belt 13, and the specific connection method is: the No. 2 magic hook surface sticker is sewn at the lower end of the right side of the No. 1 neck pressure belt 2, and the No. 3 magic wool surface sticker is sewn at the lower end of the left side of the No. 2 neck pressure belt 13. The No. 2 magic hook surface sticker cooperates with the No. 3 magic wool surface sticker to connect the No. 2 neck pressure belt 13 to the No. 1 neck pressure belt 2. The No. 2 pressure part is set on the front side of the No. 2 neck pressure belt 13, and the structure of the No. 2 pressure part is the same as that of the No. 1 pressure part.

[0053] Due to the presence of the No. 2 neck pressure belt 13 and the No. 2 pressure part, when the left and right sides of the patient need to be bandaged with pressure, the No. 2 neck pressure belt 13 can be connected to the No. 1 neck pressure belt 2 very conveniently. The other side of the patient is effectively pressurized by the No. 2 pressure part. If the No. 2 neck pressure belt 13 is designed to be detachably connected to the waist elastic belt 1, this will have a negative impact on the elasticity of the waist elastic belt 1. Because the connection structure may limit the normal stretching of the waist elastic belt 1, especially for fatter patients, when the waist elastic belt 1 is subjected to greater pressure and stretching, this problem of reduced elasticity caused by connecting the No. 2 neck pressure belt 13 will be more prominent, and may even make the waist elastic belt 1 unable to be used normally. The design of connecting the No. 2 neck pressure belt 13 to the No. 1 neck pressure belt 2 cleverly avoids this problem and ensures the normal function of the waist elastic belt 1.

[0054] Example 5 On the basis of Examples 1-3, Figure 8 As shown, the specific connection method of the detachable connection between the No. 2 neck pressure belt 13 and the No. 1 neck pressure belt 2 is as follows: four buttons 22 are sewn in a matrix arrangement at the lower end of the right side of the No. 1 neck pressure belt 2. Correspondingly, a plurality of buckles 23 are provided on both sides of the lower end of the No. 2 neck pressure belt 13. Through the cooperation between the buckles 23 and the buttons 22, the No. 2 neck pressure belt 13 can be connected to the No. 1 neck pressure belt 2, thereby realizing the combined use of the two.

[0055] Multiple buckles 23 are designed on both sides of the No. 2 neck compression belt 13. When it is found that the stretching amount on both sides is different, the buckles 23 at different positions can be connected and fixed with the corresponding buttons 22 to change the actual effective length of both sides, so as to achieve precise adjustment of the stretching amount until the stretching amount on both sides tends to be consistent. In this way, the No. 2 neck compression belt 13 can provide uniform and stable pressure on the patient's neck, significantly enhancing the patient's wearing comfort.

[0056] Example 6 On the basis of Examples 1-3, Fig. 9 As shown, a pull ring 24 is glued to the bottom of the airbag body 7 , and when the airbag is placed inside the pressurized bag 5 , the pull ring 24 is arranged toward the open end of the pressurized bag 5 .

[0057] like Fig.10 As shown, a connection block 25 is sewn on the rear side of the waist elastic belt 1 . The connection block 25 is made of hard cloth, and a connection channel is formed between the connection block 25 and the waist elastic belt 1 .

[0058] like Fig.11As shown, the No. 1 neck pressure belt 2 is provided with a No. 2 adjustment unit, which includes a Japanese-shaped buckle 26, which is arranged on the No. 1 neck pressure belt 2. The specific connection method is as follows: first, the front end of the No. 1 neck pressure belt 2 is inserted from the upper front of the Japanese-shaped buckle 26, then bypasses the middle cross bar of the Japanese-shaped buckle 26, and then passes out from the bottom of the Japanese-shaped buckle 26. Then, the No. 1 neck pressure belt 2 passing through the bottom of the Japanese-shaped buckle 26 is passed into the inside of the connecting channel from the bottom of the connecting channel and passes out from the top of the connecting channel. Finally, the No. 1 neck pressure belt 2 passing through the connecting hole is wrapped around the middle cross bar on the back of the Japanese-shaped buckle 26 and sewn to the No. 1 neck pressure belt 2. The No. 1 neck pressure belt 2 is provided with an adjustment port 27 at a position close to the opening end of the pressure bag 5.

[0059] When wearing the No. 1 neck compression belt 2, first slide the Japanese-shaped buckle 26 downward on the No. 1 neck compression belt 2 to adjust the effective length of the No. 1 neck compression belt 2 to the maximum value, so that the patient can pass the arm through the No. 1 neck compression belt 2; then, fix the waist elastic belt 1 at the patient's waist position to achieve preliminary overall wearing positioning and basic fixation; finally, slide the Japanese-shaped buckle 26 upward in the opposite direction, and adjust the length of the No. 1 neck compression belt 2 to the most appropriate state according to the patient's individual physical characteristics and actual wearing comfort requirements, to ensure that the entire wearing process is both convenient and efficient and can fit the patient's physical condition to the greatest extent.

[0060] When the position of the airbag needs to be adjusted, first slide the Japanese-shaped buckle 26 downward, and the effective length of the No. 1 neck pressure belt 2 will increase, thereby freeing up enough space and margin for subsequent operations. At this time, the hand can easily reach into the pressure bag 5 through the adjustment port 27 pre-set on the No. 1 neck pressure belt 2, and grab the pull ring 24, and then flexibly and accurately adjust the position of the airbag. When the position of the airbag is successfully adjusted to the ideal state, slide the Japanese-shaped buckle 26 upward again to readjust the length of the No. 1 neck pressure belt 2 to the appropriate position to ensure that the entire device can maintain a stable, comfortable and efficient state after the airbag position is adjusted.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
