Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of postoperative protection for tumors, and specifically refers to an adjustable protection device for alleviating secondary pain after tumor surgery in children. Background Art
[0002] After pediatric tumor surgery, the wound needs to be bandaged and protected. However, due to the active nature of children, it is easy for the wound to be compressed by accidental touch or rolling over while sleeping, causing secondary pain in the wound.
[0003] Although existing protective products can provide enclosure and protection for wounds after pediatric tumor surgery, there are still many technical problems: (1) As protective products need to fit the child’s body, they need to be flexible so that they can be suitable for children of all sizes. However, flexible protective products have poor impact resistance. When accidentally touched or squeezed, their protective effect is difficult to guarantee, which can easily cause the wound to tear and cause secondary pain. (2) In order to improve the anti-extrusion performance of protective products, protective products need to have a certain degree of rigidity. However, protective products with greater rigidity are difficult to deform and difficult to effectively fit the children's body. The contradiction between flexibility and rigidity is usually difficult to reconcile; (3) Existing protective products are usually only static and passive protection. When a child turns over, the protective device on the wound side is usually squeezed first. This will cause a huge difference in the squeezing force on the skin on both sides of the wound, which can easily lead to wound tearing. Summary of the Invention
[0004] In response to the above technical problems, the present invention provides an adjustable protective device for alleviating secondary pain after childhood tumor surgery. The device achieves a combination of rigidity and flexibility through a protective bag with built-in electrorheological fluid. It can be deformed to adapt to various body shapes and parts of children, and has a rigid protection function. At the same time, the straps and airbag components cooperate with each other to provide active dynamic protection for patients and balance the pressure on both sides of the wound. It can also provide both rigid and flexible protection, thereby effectively preventing wound tearing and avoiding secondary pain.
[0005] The technical solution adopted by the present invention is as follows: This solution provides an adjustable protective device for relieving secondary pain after childhood tumor surgery, which consists of a strap and a dynamic protector detachably arranged in the strap. The strap is made of nylon cloth, and multiple sets of hidden buckles are arranged at both ends of the strap. The two ends of the strap can be connected together by the hidden buckles to form a restraint ring, which is convenient for fixing on the patient's body. A protective through-hole is opened through the middle of the strap, and a ring-shaped Velcro is provided on the outer wall of the strap along the edge of the protective through-hole. The outer surface of the ring-shaped Velcro is a furry surface. The dynamic protector is located in the protective through-hole. The dynamic protector includes a retaining ring, a protective bag and an airbag assembly. The retaining ring is detachably installed in the protective through-hole. Velcro is distributed in an annular array on the outer wall of the retaining ring. The surface of the Velcro close to the ring-shaped Velcro is a hook surface. The retaining ring is connected to the protective through-hole by the bonding action of the Velcro and the annular Velcro. The protective bag is installed on the inner circumferential wall of the retaining ring. A long hole is provided in the middle of the protective bag. The purpose of setting the long hole is to prevent the protective bag from being directly pressed against the patient's wound, and the long hole can also facilitate the passage of the drainage tube. The inside of the protective bag is filled with electrorheological fluid. The airbag assembly is arranged on the outer wall of the protective bag. The airbag assembly consists of two semi-lunar airbags, which are located on both sides of the long hole. The semi-lunar airbags are made of elastic rubber. The two semi-lunar airbags are connected to each other through two hoses. The two semi-lunar airbags are filled with inert gas. The semi-lunar airbags are in an expanded state due to being filled with inert gas, and the outer wall of the semi-lunar airbag protrudes from the outer wall of the strap. When the patient turns over, the semi-lunar airbag will be squeezed.
[0006] Furthermore, in order to ensure the use of the airbag assembly and prevent foreign objects from directly touching the patient's wound through the long hole, a strap is connected to the outer wall of the strap, and a Velcro is provided at the other end of the strap, and a Velcro is provided on the outer wall of the strap. The Velcro and the strap are respectively installed on both sides of the protective through-hole, and the other end of the strap can be adhered to the strap through the adhesion of the Velcro and the Velcro. The middle part of the strap surrounds the outside of the two semi-lunar airbags, limiting the two semi-lunar airbags so that the two semi-lunar airbags can only expand in the direction of the protective bag, and the strap can block the long hole to prevent the patient's wound from being touched and causing secondary pain. The strap is made of polyester fabric without stretch function, and an array of air holes are opened on the strap to improve breathability and avoid infection of the patient's wound. The pasting position of the Velcro and the Velcro can be adjusted according to usage requirements, thereby adjusting the pressure of the strap on the two semi-lunar airbags, thereby adjusting the restraint force.
[0007] The beneficial effects achieved by the present invention are as follows: (1) The dynamic protector provided by the present invention achieves a combination of rigidity and flexibility through a protective bag with built-in electrorheological fluid. It can be deformed to adapt to various body shapes and parts of children, and can also provide rigid protection, effectively solving the problem of the existing technology that is difficult to reconcile rigid protection and flexible protection; (2) The airbag assembly and the straps cooperate with each other. The straps can limit the expansion direction of the airbag assembly, so that when the patient turns over, the airbag assembly can expand toward the protective bag, thereby balancing the pressure of the protective bag on both sides of the patient's wound. The airbag assembly in turn supports the straps, thereby forming an elastic protective layer on the outside of the protective bag, and together with the protective bag, forming a double-layer protection that is both rigid and flexible, which significantly improves the protection effect and reduces the possibility of secondary pain in the wound caused by squeezing and touching. At the same time, the sticking position of the Velcro and Velcro mother strips can be adjusted according to the needs of use, thereby adjusting the pressure of the straps on the two half-moon airbags, thereby adjusting the restraint strength; (3) The retaining ring and the protective through hole are both circular. Therefore, the retaining ring can be rotated before use to adjust the angle of the retaining ring so that the long hole is consistent with the direction of the patient's surgical incision, which improves the applicability of the device. At the same time, the long hole can also facilitate the passage of the drainage tube. For patients who need postoperative drainage, passing the drainage tube through the long hole can effectively prevent the drainage tube from being accidentally touched or crushed, resulting in the risk of drainage failure or infection. (4) The semilunar airbag is in an expanded state due to being filled with inert gas, and the outer wall of the semilunar airbag protrudes from the outer wall of the band. When the patient turns over, the semilunar airbag can be squeezed, thereby achieving gas transfer and pressure balance; (5) The ventilation holes on the bandage can improve breathability and prevent the patient's wound from being infected.

[0011] Example 1: Please refer to Figures 1-6The present embodiment provides an adjustable protective device for relieving secondary pain after pediatric tumor surgery, which consists of a strap 1 and a detachable dynamic protector 2 arranged in the strap 1. The strap 1 is made of nylon cloth, and multiple sets of hidden buckles are arranged at both ends of the strap 1. The two ends of the strap 1 can be connected together by the hidden buckles to form a restraint circle, and the connection points at both ends of the strap 1 can be adjusted by the hidden buckles, thereby adjusting the size of the restraint circle formed by the strap 1 as a whole, which is convenient for fixing on the patient's body, and can adapt to patients of various body shapes and various parts of the patient's body, and can also adjust the restraint strength. A protective through hole 111 is opened through the middle of the strap 1, and the protective through hole 111 is circular. The outer wall of the strap 1 is along the protective through hole An annular Velcro 112 is provided on the edge of 111, and the outer surface of the annular Velcro 112 is a furry surface. The dynamic protector 2 is located in the protective through-hole 111. The dynamic protector 2 includes a retaining ring 21, a protective bag 22 and an airbag assembly 23. The retaining ring 21 is detachably installed in the protective through-hole 111. The retaining ring 21 is made of flexible rubber. When in use, the retaining ring 21 is located on the side of the protective through-hole 111 close to the patient's body. The retaining ring 21 is attached to the patient's skin. The outer diameter of the retaining ring 21 is larger than the inner diameter of the protective through-hole 111. Therefore, the edge of the protective through-hole 111 can limit the retaining ring 21. The outer wall of the retaining ring 21 is distributed in an annular array with Velcro ear stickers 211. The Velcro ear stickers 211 are close to the side of the annular Velcro 112. The surface is a hook surface, and the retaining ring 21 is connected to the protective through hole 111 by the bonding effect of the Velcro 211 and the ring Velcro 112. The protective bag 22 is installed on the inner circumferential wall of the retaining ring 21, and a long hole 221 is provided in the middle of the protective bag 22. The purpose of setting the long hole 221 is to prevent the protective bag 22 from being directly pressed against the patient's wound, and the long hole 221 can also facilitate the passage of the drainage tube. For patients who need postoperative drainage, passing the drainage tube through the long hole 221 can effectively prevent the drainage tube from being accidentally touched or crushed, resulting in drainage failure or infection risks. Since the retaining ring 21 and the protective through hole 111 are both circular, the retaining ring 21 can be rotated before use to adjust the angle of the retaining ring 21 so that the long hole 221 is not too tight. 21 is consistent with the direction of the patient's surgical incision, the protective bag 22 is filled with electrorheological fluid, and the electrorheological fluid inside the protective bag 22 is connected to an external power supply through a wire. The airbag assembly 23 is arranged on the outer wall of the protective bag 22, and the airbag assembly 23 is composed of two semi-lunar airbags 231. The two semi-lunar airbags 231 are respectively located on both sides of the long hole 221. The semi-lunar airbags 231 are made of elastic rubber. The two semi-lunar airbags 231 are connected to each other through two hoses 232. The two semi-lunar airbags 231 are filled with argon gas. The semi-lunar airbags 231 are in an expanded state due to being filled with argon gas, and the outer wall of the semi-lunar airbag 231 protrudes from the outer wall of the belt 1. When the patient turns over, the semi-lunar airbags 231 can be squeezed.
[0012] In order to ensure that the airbag assembly 23 can squeeze the protective bag 22 and prevent foreign matter from directly touching the patient's wound through the long hole 221, a strap 121 is connected to the outer wall of the strap 1, and a magic tape 122 is provided at the other end of the strap 121. A magic tape 123 is provided on the outer wall of the strap 1. The magic tape 123 and the strap 121 are respectively installed on both sides of the protective through hole 111, and the other end of the strap 121 can be attached to the strap 1 through the adhesion of the magic tape 122 and the magic tape 123. The middle part of the strap 121 surrounds the outside of the two semi-lunar airbags 231, which 231 is limited so that the two half-moon-shaped airbags 231 can only expand toward the protective bag 22, and the strap 121 can block the long hole 221 to prevent the patient's wound from being touched and causing secondary pain. The strap 121 is made of polyester fabric without an extensible function, and an array of air holes 124 are opened on the strap 121 to improve the breathability and avoid infection of the patient's wound. The pasting position of the Velcro 122 and the Velcro mother sticker 123 can be adjusted according to the use requirements, thereby adjusting the pressure of the strap 121 on the two half-moon-shaped airbags 231, thereby adjusting the restraint force.
[0013] When this embodiment is used, the dynamic protector 2 is aligned with the patient's surgical wound and is tied with the strap 1 and worn on the patient's body to achieve dynamic protection.
[0014] The specific operation process is as follows: first, open the hidden buckles at both ends of the strap 1, and stick the Velcro 122 on the strap 121 and the Velcro 123 on the strap 1 together, so that the strap 121 is reliably connected to the strap 1, and adjust the angle of the retaining ring 21 according to the direction of the patient's surgical incision so that the long hole 221 is consistent with the direction of the patient's surgical incision, align the dynamic protector 2 with the patient's surgical wound, and then wrap the two ends of the strap 1 around the patient's body and connect the hidden buckles at both ends of the strap 1 together so that the strap 1 as a whole is in a tight state. In the initial state, the electrorheological fluid filled in the protective bag 22 is not energized, so the electrorheological fluid is flexible, and the protective bag 22 as a whole is flexible. Since the strap 1 and the retaining ring 21 are made of flexible materials, the dynamic protector 2 as a whole can be deformed and fitted according to the curve of the patient's body. The protective bag 22 fits around the patient's surgical wound, and the surgical wound is located in the long hole 221, and the device is worn.
[0015] Then, the electrorheological fluid filled in the protective bag 22 is energized by controlling the external power supply. The electrorheological fluid changes to a solid state under the energized state and has strong rigidity. Therefore, the protective bag 22 will become rigid, thereby improving the anti-collision effect.
[0016] When lying down, child patients often turn over involuntarily. When the patient turns his body, the strap 1 and the dynamic protector 2 move. When one side of the dynamic protector 2 is squeezed, the semi-lunar airbag 231 on that side will be squeezed, and the argon gas in the semi-lunar airbag 231 on that side will be squeezed from the hose 232 to the other semi-lunar airbag 231, causing the other semi-lunar airbag 231 to expand and become larger. Due to the setting of the strap 121, the semi-lunar airbag 231 can only expand toward the protection bag 22. Therefore, the above-mentioned expanded semi-lunar airbag 231 will squeeze the protection bag 22 at its position toward the patient's body, thereby balancing the squeezing force of the protection bag 22. Through the above-mentioned setting, the squeezing force can be balanced. When the patient turns over, the protection bag 22 will evenly squeeze both sides of the surgical wound to avoid wound tearing due to unilateral squeezing.
[0017] During normal protection, the strap 121 can prevent external forces from touching the wound, and the semi-lunar airbag 231 supports the middle part of the strap 121, forming an elastic protective layer on the periphery of the device, and the internal protective bag 22 forms a rigid protective layer. The combination of rigidity and flexibility provides better protection. At the same time, the air holes 124 set on the strap 121 can improve air permeability and prevent the patient's wound from being infected.
[0018] For patients who need drainage, the drainage tube can be passed through the long hole 221, thereby effectively preventing the drainage tube from being accidentally touched or crushed, thereby preventing the risk of drainage failure or infection.
[0019] The present invention and its embodiments are described above. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
