Adjustable wide fast hemostatic inflatable bandage

Abstract

This invention relates to the field of hemostatic inflatable bandages and discloses an adjustable-width, rapid hemostatic inflatable bandage, comprising a bending spring device housing, a gas cylinder transmission pipe at the top of the bending spring device housing, and a disposable gas cylinder fixedly installed at the top of the gas cylinder transmission pipe. This adjustable-width, rapid hemostatic inflatable bandage utilizes the rapid bending capability of the bending spring device housing to pre-stop bleeding at the anterior segment of a patient's arm injury. During bending, carbon dioxide from the disposable gas cylinder rapidly enters the inflatable pressure band, causing it to quickly envelop and expand, achieving the effect of compressing the hemostatic point. Simultaneously, the device achieves a magnetic locking effect through the magnetic attraction between the negative magnetic band and the positive magnetic block. Furthermore, the positive magnetic block and the adjustable slot in the bending spring device housing attract each other and slide into the adjustable slot for rapid fixation.

Description

Technical Field

[0001] This invention relates to the field of hemostatic inflatable bandage technology, specifically to an adjustable-width hemostatic inflatable bandage for rapid hemostasis. Background Technology

[0002] When a patient has a large wound on their arm that is bleeding continuously, immediate hemostasis is necessary. Wound hemostasis requires rapid and forceful pressure to slow the blood flow and form a blood clot at the wound site, preventing further bleeding. Existing technologies, besides manual pressure, can also use tourniquets for hemostasis. However, existing tourniquets require both hands to operate, and the process is cumbersome. Inexperienced operators may experience severe bleeding. During hemostasis, the wound is exposed to air for an extended period, which can easily lead to bacterial infection and endanger life. After using a wound dressing patch for hemostasis, replacing the contaminated dressing patch requires disassembling the device, which is cumbersome and impractical. Furthermore, during the installation and replacement of the disposable gas cylinder, the connection is prone to looseness, preventing the disposable gas cylinder from being quickly inflated. Unstable pressure results in poor hemostasis and low safety. Therefore, this invention provides an adjustable-width, rapid hemostatic inflatable tourniquet. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an adjustable-width, rapid hemostatic tourniquet with advantages such as adaptability to different arm sizes for rapid hemostasis, quick roll-up for changing wound dressings, and tight connection. It solves the problems raised in the prior art, including the requirement for two-handed operation of existing tourniquets, the cumbersome hemostasis process, the potential for severe bleeding due to unfamiliarity with the procedure, the prolonged exposure of the wound to air during hemostasis leading to bacterial infection and potentially life-threatening complications, the need to disassemble the device to replace contaminated wound dressings after hemostasis (a cumbersome and impractical process), and the issue that loose connections at the disposable gas cylinder during installation and replacement can prevent rapid inflation, resulting in unstable pressure, poor hemostasis, and low safety.

[0005] Preferably, two fixing plates are fixedly connected to the bottom of the inner shell of the bending spring device. Each of the two fixing plates is provided with an auxiliary sliding device on its side. A connecting sleeve is fixedly connected to the side of the auxiliary sliding device.

A magnet plate is fixedly installed on the surface of the winding column.

[0006] Preferably, a fixed sleeve is fixedly connected to the bottom of the inner wall of the bending spring device housing. Wall grooves are respectively opened on both sides of the inner wall of the fixed sleeve. A spring is fixedly installed on one side of the inner wall of the wall groove. An arc-shaped locking block is fixedly installed on the other end of the spring. A connecting block is attached to the surface of the arc-shaped locking block. An installation groove is opened on the upper surface of the connecting block. An internally threaded sleeve is fixedly engaged inside the installation groove. The internal thread of the internally threaded sleeve is connected to threaded teeth. A gas cylinder transmission pipe is fixedly connected inside the threaded teeth.

[0007] Preferably, the silicone rubber adhesive sheet is prepared by means of a mesh silicone sheet, medical wound dressing, and silicone patch.

[0008] Preferably, a magnetic strip is provided on the side of the magnetic plate, and a silicone rubber adhesive sheet is fixedly installed on the other side of the magnetic strip.

[0009] Preferably, the auxiliary sliding device includes an auxiliary sliding device housing, ball bearings, and a connecting plate. The auxiliary sliding device housing is fixedly connected to the side of the fixed plate. The ball bearings are disposed inside the auxiliary sliding device housing. The connecting plate is attached to the surface of the ball bearings. A rotating sleeve is fixedly connected to the side of the connecting plate.

[0010] Preferably, connecting blocks are attached to both sides of the inner wall of the fixed sleeve, and arc-shaped grooves are respectively opened on both sides of the connecting blocks, and arc-shaped locking blocks are provided inside the arc-shaped grooves.

[0011] Preferably, a circular groove is provided at the top of the inside of the bending spring device housing, a pressure belt transmission tube is fixedly connected inside the circular groove, and an inflation pressure belt is fixedly connected to the bottom of the pressure belt transmission tube.

[0012] Preferably, a pressure band transmission tube is fitted inside the mounting groove, and an internally threaded sleeve is fitted to the top of the pressure band transmission tube.

[0013] Preferably, the magnetic properties of the magnet plate and the magnetic strip are different.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This adjustable-width, rapid hemostatic inflatable bandage, consisting of a disposable gas cylinder, a negative magnetic strap, a positive magnet, an adjustable slot, and an inflation pressure band, utilizes the rapid bending capability of the flexible spring housing to pre-stop hemorrhage at the front of the patient's arm injury. During bending, carbon dioxide from the disposable gas cylinder quickly enters the inflation pressure band, causing it to rapidly envelop and expand, effectively compressing the hemostatic point. Simultaneously, the magnetic attraction between the negative magnetic strap and the positive magnet creates a magnetic locking effect. Furthermore, the overlap between the positive magnet and the adjustable slot in the flexible spring housing allows for mutual attraction and slides into the slot, achieving rapid fixation.

[0016] 2. This adjustable-width, quick-acting hemostatic inflatable band, equipped with ball bearings, a connecting plate, a magnetic plate, and a magnetic strip, allows for easy replacement of silicone rubber adhesive sheets. The new adhesive sheet is inserted into the groove on the side of the bending spring device housing. During insertion, the magnetic strip on the side of the adhesive sheet and the magnetic plate fixedly mounted on the surface of the winding column create a magnetic attraction. As the adhesive sheet slides into the bending spring device housing, the connecting plate fixedly mounted on the surface of the rotating sleeve rotates under the action of the ball bearings inside the auxiliary sliding device housing. This rotation of the winding column causes the new silicone rubber adhesive sheet to be wound up and installed. During use, the magnetic attraction can be manually separated. The entire installation and replacement process is simple and highly practical.

[0017] 3. This adjustable-width, rapid hemostatic inflatable band, through the inclusion of springs, arc-shaped locking blocks, threaded teeth, a gas cylinder transfer tube, and an internally threaded sleeve, allows for the installation of new disposable gas cylinders. The gas cylinder transfer tube on the side of the disposable gas cylinder is pre-inserted into the housing of the bending spring device. During insertion, the threaded teeth on the surface of the gas cylinder transfer tube contact the internally threaded sleeve, which is fixedly engaged in the mounting groove at the top of the connecting block, forming a threaded connection. When the gas cylinder transfer tube on the side of the disposable gas cylinder exerts downward pressure on the connecting block, the spring on the side of the arc-shaped locking block contracts within the wall groove of the connecting block until the arc-shaped locking block engages with the arc-shaped grooves on both sides of the connecting block. Simultaneously, utilizing the tightness of the threaded connection, the gas cylinder transfer tube on the side of the disposable gas cylinder indirectly forms a passage through the internally threaded sleeve and the pressure band transfer tube at the top of the inflation pressure band within the mounting groove of the connecting block. This ensures a tight connection between the two components and further enhances the tightness of the connection through the engagement of the arc-shaped locking block with the arc-shaped grooves on both sides of the connecting block.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0028] Please see Figure 1-2An adjustable-width, rapid hemostatic inflatable band includes a bending spring device housing 1. A negative magnetic strap 31 is provided on the side of the bending spring device housing 1. An adjustable slot 2 is formed on the upper surface of the bending spring device housing 1. A positive magnet block 8 is fixedly installed on the lower surface of the bending spring device housing 1. An inflatable pressure band 7 is fixedly installed at the bottom of the bending spring device housing 1. A sliding groove 6 is formed on the side of the bending spring device housing 1, and a pull strip 3 is fitted inside the sliding groove 6. The bending spring device housing 1 allows for rapid bending. The device has the characteristics of pre-stopping hemorrhage at the front of the patient's arm injury. During the bending process, the carbon dioxide in the disposable gas cylinder 5 quickly enters the inflation pressure band 7. The inflation pressure band 7 quickly covers and expands to achieve the effect of compressing the hemostasis point. At the same time, the device achieves the effect of magnetic locking through the magnetic attraction between the negative magnetic strap 31 and the positive magnetic block 8. Then, through the overlapping relationship between the positive magnetic block 8 and the adjustable slot 2 opened in the bending spring device shell 1, they attract each other and slide into the adjustable slot 2 to achieve the effect of quick fixation. Example 2

[0029] Please see Figure 1 , Figure 3 , Figure 5 as well as Figure 6An adjustable-width, rapid hemostatic inflatable band is provided. A gas cylinder transmission pipe 4 is located at the top of the bending spring device housing 1, and a disposable gas cylinder 5 is fixedly installed at the top of the gas cylinder transmission pipe 4. Silicone rubber adhesive sheets 9 are fixedly installed on the side of the pull strip 3. Two fixing plates 16 are fixedly connected to the bottom inside the bending spring device housing 1. Each fixing plate 16 has an auxiliary sliding device 11 on its side. A connecting sleeve 12 is fixedly connected to the side of the auxiliary sliding device 11. A rotating groove 35 is opened on the side of the connecting sleeve 12, and a rotating sleeve 13 is movably connected inside the rotating groove 35. An internally fixed winding post 14 is attached, and a magnetic plate 10 is fixedly installed on the surface of the winding post 14. Magnetic strips 15 are provided on the side of the magnetic plate 10. The magnetic strips 15 on the side of the silicone rubber adhesive sheet 9 and the magnetic plate 10 fixedly installed on the surface of the winding post 14 generate magnetic attraction. As the silicone rubber adhesive sheet 9 continuously slides into the bending spring sheet housing 1, the connecting plate 20 fixedly installed on the surface of the rotating sleeve 13 on the side of the winding post 14 rotates under the action of the ball bearings 19 inside the auxiliary sliding housing 18. Thus, during the rotation of the winding post 14, new silicone rubber adhesive sheets 9 are wound and installed. Simultaneously, the silicone rubber adhesive sheet 9 is used... The magnetic separation can be performed manually during the process, making the entire installation and replacement process simple and more practical. A silicone rubber adhesive sheet 9 is fixedly installed on the other side of the magnetic strip 15. The auxiliary sliding device 11 includes an auxiliary sliding housing 18, ball bearings 19, and a connecting plate 20. The auxiliary sliding housing 18 is fixedly connected to the side of the fixing plate 16. Ball bearings 19 are installed inside the auxiliary sliding housing 18, and the connecting plate 20 is attached to the surface of the ball bearings 19. A rotating sleeve 13 is fixedly connected to the side of the connecting plate 20. The magnetic plate 10 and the magnetic strip 15 have the same magnetism. The silicone rubber adhesive sheet 9 is connected to the mesh silicone sheet. 21. The medical wound dressing 22 and the silicone patch 23 are prepared. The mesh silicone patch 21 has a very light weight, good flexibility and high durability. It can be bent freely and is easy to store and use. The mesh silicone patch 21 made using these characteristics has good breathability. The medical wound dressing 22 can isolate the wound from the external environment, enhance hemostasis and reduce the probability of wound infection, reduce the patient's pain, and reduce scarring after healing. The silicone patch 23 is used to support the medical wound dressing 22. It can make it easy for the user to adhere and cover the wound to achieve the effect of rapid hemostasis. Example 3

[0030] Please see Figure 4 , Figure 7 as well as Figure 8An adjustable-width, quick-closing hemostatic inflatable band is provided. A fixed sleeve 17 is fixedly connected to the bottom of the inner end of the curved spring device housing 1. Wall grooves 24 are formed on both sides of the inner wall of the fixed sleeve 17. A spring 25 is fixedly installed on one side of the inner wall of the wall groove 24, and an arc-shaped locking block 26 is fixedly installed on the other end of the spring 25. A connecting block 27 is attached to the surface of the arc-shaped locking block 26. An installation groove 32 is formed on the upper surface of the connecting block 27. An internally threaded sleeve 33 is fixedly engaged inside the installation groove 32. Threaded teeth 34 are connected to the internal threads of the internally threaded sleeve 33. A gas cylinder transmission pipe 4 is fixedly connected inside the threaded teeth 34. Connecting blocks 27 are attached to both sides of the inner wall of the fixed sleeve 17. Arc-shaped grooves 30 are formed on both sides of the connecting blocks 27. Arc-shaped locking blocks 26 are set inside the arc-shaped grooves 30. A circular groove 29 is formed at the top of the inner end of the curved spring device housing 1. A pressure band transmission pipe 28 is fixedly engaged inside the circular groove 29. The bottom of 28 is fixedly connected to an inflation pressure band 7. The inside of the mounting groove 32 is fitted with a pressure band transmission tube 28. The top of the pressure band transmission tube 28 is fitted with an internal threaded sleeve 33. When the gas cylinder transmission tube 4 on the side of the disposable gas cylinder 5 is inserted into the curved spring device housing 1, it exerts downward pressure on the connecting block 27. During the downward pressure, the spring 25 on the side of the arc-shaped locking block 26 contracts inside the wall groove 24 opened in the connecting block 27 until the arc-shaped locking block 26 engages with the arc-shaped grooves 30 opened on both sides of the connecting block 27. At the same time, by utilizing the tight characteristics of the threaded connection, the gas cylinder transmission tube 4 on the side of the disposable gas cylinder 5 is indirectly connected to the mounting groove 32 opened in the connecting block 27 through the internal threaded sleeve 33 and the pressure band transmission tube 28 at the top of the inflation pressure band 7. This ensures a tight connection between the two and enhances the tightness of the connection through the engagement of the arc-shaped locking block 26 with the arc-shaped grooves 30 opened on both sides of the connecting block 27.

[0031] Working principle: When hemostasis is needed, the device is picked up with one hand and aimed at the front end of the bleeding site on the patient's arm. The bending spring device housing 1 quickly bends to wrap around the front part of the patient's arm injury. During the bending process of the bending spring device housing 1, carbon dioxide in the disposable gas cylinder 5 is transferred from the gas cylinder transmission tube 4 to the inflation pressure band 7 through the pressure band transmission tube 28. The inflation pressure band 7 quickly covers and expands to compress the hemostasis point. Then, the silicone rubber adhesive sheet 9 is pulled out by the pull strip 3 inside the sliding groove 6 on the side of the bending spring device housing 1. The silicone rubber adhesive sheet 9 covers the hemostasis point. To isolate the wound from the external environment, a new silicone rubber adhesive sheet 9 needs to be installed. During the process of inserting the new silicone rubber adhesive sheet 9 into the groove 6 on the side of the bending spring device housing 1, the magnetic strip 15 on the side of the silicone rubber adhesive sheet 9 and the magnet plate 10 fixedly installed on the surface of the winding column 14 generate magnetic attraction. As the silicone rubber adhesive sheet 9 slides into the bending spring device housing 1, the connecting plate 20 fixedly installed on the surface of the rotating sleeve 13 on the side of the winding column 14 rotates under the action of the ball bearings 19 inside the auxiliary sliding device housing 18, thereby winding... During the rotation of the column 14, the new silicone rubber adhesive sheet 9 is wound up and installed until the winding is completed. The pull strip 3 is attached to the sliding groove 6 opened on the side of the bending spring device housing 1. When a new disposable gas cylinder 5 needs to be installed, the gas cylinder transmission pipe 4 on the side of the disposable gas cylinder 5 is inserted into the bending spring device housing 1 beforehand. When the threaded teeth 34 fixedly connected on the surface of the gas cylinder transmission pipe 4 contacts the internal threaded sleeve 33 fixedly engaged in the mounting groove 32 opened on the top of the connecting block 27, the rotation is performed to form a threaded connection. At the same time, the gas cylinder 5 passes through the side of the disposable gas cylinder. When the bottle transfer tube 4 is inserted into the bending spring device housing 1, it exerts downward pressure on the connecting block 27. During the downward pressure, the spring 25 on the side of the arc-shaped locking block 26 contracts inside the wall groove 24 opened in the connecting block 27 until the arc-shaped locking block 26 engages with the arc-shaped grooves 30 opened on both sides of the connecting block 27. At the same time, taking advantage of the tight connection of the threaded connection, the gas cylinder transfer tube 4 on the side of the disposable gas cylinder 5 indirectly forms a passage through the internal threaded sleeve 33 and the pressure band transfer tube 28 at the top of the inflation pressure band 7 inside the mounting groove 32 opened in the connecting block 27.
