[0001] This utility model relates to the field of medical device technology, specifically to a hemostatic bag belt with adjustable micro-pressure. Background Technology

[0002] For patients with arterial or venous bleeding, medical staff use a band-like tool to tighten the affected limb to stop the bleeding. However, excessive tightening can easily cause severe obstruction of blood flow.

[0003] Therefore, how to design a hemostatic bag that can adjust the compression area according to needs has become an urgent problem to be solved in the field of medical device technology. Utility Model Content

[0004] The purpose of this invention is to provide a micro-pressure adjustable hemostatic bag, which uses the A-bag to compress the wound to stop bleeding, avoiding excessive tightening that could cause severe obstruction of blood flow. The A-bag compression area can also be adjusted as needed, making it suitable for wounds of different sizes.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] A micro-pressure adjustable tourniquet includes a fixing plate with a skin-contacting surface and an exposed surface. The fixing plate has an inflation port, an air bladder, and a movable shaping element. The air bladder is fixed to the skin-contacting surface of the fixing plate, and the shaping element is clamped to the surface of the air bladder. The air bladder is divided into bladder A and bladder B by the shaping element. The inflation port is located on the exposed surface of the fixing plate and communicates with the cavity of bladder A. After inflation, bladder A expands: when the shaping element moves to one side, the surface area of ​​bladder A increases and the surface area of ​​bladder B decreases; when the shaping element moves to the other side, the surface area of ​​bladder A decreases and the surface area of ​​bladder B increases. Straps are provided on both sides of the fixing plate. The skin-contacting surface of the fixing plate covers the wound on the affected limb, and the straps are wrapped around the periphery of the affected limb and secured with Velcro, allowing bladder A to apply pressure to the wound for hemostasis.

[0007] Compared with existing technologies, the micro-pressure adjustable tourniquet using the above-mentioned technical solution has the following beneficial effects:

[0008] 1. The micro-pressure adjustable hemostatic bag of this utility model is used. The fixing plate is worn on the wound of the affected limb. Air is injected through the air port to expand the shape of the bag, so as to play the role of compression hemostasis and avoid excessive tightening that would cause serious obstruction of blood flow.

[0009] 2. The movable shaping component for medical staff can adjust the pressure area of ​​the A-bag according to needs, and is suitable for wounds of different sizes.

[0010] Preferably, the fixed plate has a groove at the center of the skin-contact surface, the airbag is located on the groove surface, and there are two shaping parts. The two shaping parts are respectively clamped on both sides of the airbag surface, that is, there are two B bags, and the A bag is located in the middle of the two B bags. The two shaping parts move closer to each other and further away from each other.

[0011] Preferably, the fixing plate contains a gear and two racks, with each side of the gear meshing with one of the racks. A rotatable core is located on the exposed surface of the fixing plate, with its inner end fixed to the gear's rotation center. Two shaping components are fixed to the two racks respectively. When the core rotates forward, it causes the two shaping components to move away from each other, increasing the surface area of ​​the A-sac. When the core rotates in the reverse direction, it causes the two shaping components to move closer together, decreasing the surface area of ​​the A-sac. The distance between the two shaping components is controlled by rotating the core, thus adjusting the A-sac compression area, making operation simple.

[0012] Preferably, it also includes a locking button, below which is a core-retaining groove and several locking holes. The outer end of the core extends and retracts within the core-retaining groove. A slider is provided on the outer circumferential surface of the core, and a groove is provided on the inner circumferential surface of the core-retaining groove. The slider is confined within the groove. Several locking holes are arranged circumferentially along the outer edge of the core-retaining groove opening. A locking block adapted to the locking holes is provided on the exposed surface of the fixing plate: when the outer end of the core retracts, the locking button moves towards the fixing plate, and the locking block engages with the locking hole; when the outer end of the core extends, the locking button moves away from the fixing plate, and the locking block disengages from the locking hole. After the locking block engages with the locking hole, it can prevent the core from rotating accidentally and maintain the A-sac compression area unchanged.

[0013] Preferably, the exposed surface of the fixing plate is equipped with a magnet, and the bottom of the lock button is magnetically connected to the exposed surface of the fixing plate via the magnet. This magnetic attraction prevents the lock block from accidentally dislodging from the lock hole.

[0014] Preferably, a pressure sensor is installed inside the A-bag to detect the pressure of the A-bag. A display is installed on the exposed surface of the fixation plate, and the display is electrically connected to the pressure sensor. The display screen shows the pressure value of the A-bag. During inflation and deflation, medical staff can check the display screen to know the changes in the pressure of the A-bag.

[0015] Preferably, it also includes an inflatable balloon, which is equipped with an air supply tube and a deflation valve. The inflatable balloon can be similar to the balloon in existing blood pressure cuffs, with the air supply tube connected to the inflation port. Medical staff inflate the balloon by squeezing the inflation port and deflate it by opening the deflation valve. The pressure of the balloon can be adjusted as needed, making the operation simple.

[0016] Preferably, the fixation plate is made of a transparent material. After the fixation plate is worn on the wound of the affected limb, medical staff can see the position of the shaping component through the fixation plate, which makes it easy to adjust the pressure area of ​​the A-sac.

Detailed Implementation

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figures 1 to 9The micro-pressure adjustable tourniquet shown includes a fixing plate 1, with a skin-contact surface and an exposed surface on both sides. The fixing plate 1 is provided with an inflation port 3, an air bladder 22, and a movable shaping component 2. The air bladder 22 is fixed to the skin-contact surface of the fixing plate 1, and the shaping component 2 is clamped to the surface of the air bladder 22. The air bladder 22 is divided into an A bladder 23 and a B bladder 24 by the shaping component 2. The inflation port 3 is located on the exposed surface of the fixing plate 1 and is connected to the cavity of the A bladder 23. After the air bladder 23 is inflated by the inflation port 3, the A bladder 23 expands: when the shaping component 2 moves to one side, the surface area of ​​the A bladder 23 increases and the surface area of ​​the B bladder 24 decreases; when the shaping component 2 moves to the other side, the surface area of ​​the A bladder 23 decreases and the surface area of ​​the B bladder 24 increases. The fixation plate 1 has straps 13 on both sides. The skin-contact side of the fixation plate 1 covers the wound of the affected limb, and the straps 13 are wrapped around the periphery of the affected limb and secured with Velcro, allowing the A-bag 23 to compress the wound for hemostasis. When the fixation plate 1 is worn on the wound of the affected limb, air is injected through the inflation port 3 to inflate the A-bag 23, achieving the effect of compression and hemostasis, while avoiding excessive tightening that could severely obstruct blood flow. Medical staff can move the shaping component 2 to adjust the compression area of ​​the A-bag 23 as needed, making it suitable for wounds of different sizes.

[0029] Reference Figure 2 and Figure 3 The fixing plate 1 has a groove 21 at the center of the skin-contact surface. The airbag 22 is located on the groove surface of the groove 21. There are two shaping parts 2. The two shaping parts 2 are respectively clamped on both sides of the surface of the airbag 22, that is, there are two B bags 24. The A bag 23 is located in the middle of the two B bags 24. The side of the shaping part 2 near the A bag 23 has a semi-circular empty groove 20. The A bag 23 is exposed in the empty groove 20 of the two shaping parts 2. The two shaping parts 2 move closer and further away from each other.

[0030] Reference Figures 4 to 8 The fixed plate 1 contains a gear 61 and two racks 62. The gear 61 meshes with the two racks 62 on both sides. A rotatable core 5 is located on the exposed surface of the fixed plate 1. The inner end of the core 5 is fixed to the rotation center of the gear 61. Two shaping components 2 are fixed to the two racks 62 respectively. When the core 5 rotates forward, it causes the two shaping components 2 to move away from each other, increasing the surface area of ​​the A-bag 23. When the core 5 rotates in the reverse direction, it causes the two shaping components 2 to move closer together, decreasing the surface area of ​​the A-bag 23. The distance between the two shaping components 2 can be controlled by rotating the core 5, thus adjusting the compression area of ​​the A-bag 23. The operation is simple.

[0031] This invention also includes a locking button 4, which has a core-retaining groove 41 and several locking holes 43 below it. The outer end of the core 5 extends and retracts within the core-retaining groove 41. A slider 52 is provided on the outer circumferential surface of the core 5, and a sliding groove 42 is provided on the inner circumferential surface of the core-retaining groove 41. The slider 52 is confined within the sliding groove 42, causing the locking button 4 to rotate the core 5 in the same direction. Several locking holes 43 are arranged circumferentially along the outer edge of the core-retaining groove 41. The exposed surface of the fixing plate 1 is provided with locking blocks 53 that are adapted to the locking holes 43: when the outer end of the core 5 retracts, the locking button 4 moves toward the fixing plate 1, and the locking blocks 53 engage with the locking holes 43; when the outer end of the core 5 extends, the locking button 4 moves away from the fixing plate 1, and the locking blocks 53 disengage from the locking holes 43. After the locking blocks 53 engage with the locking holes 43, they can prevent the core 5 from rotating accidentally, keeping the pressure area of ​​the A-bag 23 unchanged.

[0032] The outer surface of the lock button 4 has anti-slip texture to increase friction and make it easier to turn the lock button 4. The upper end of the lock block 53 is hemispherical, which serves as a transition and makes it easier to snap the lock block 53 into the lock hole 43.

[0033] The exposed surface of the fixing plate 1 is equipped with a magnet 51, and the bottom of the locking button 4 is magnetically connected to the exposed surface of the fixing plate 1 via the magnet 51. The magnetic attraction of the magnet 51 prevents the locking block 53 from accidentally dislodging from the lock hole 43.

[0034] A pressure sensor 12 is installed inside the A-bag 23 to detect the pressure of the A-bag 23. A display 11 is installed on the exposed surface of the fixing plate 1. The display 11 is electrically connected to the pressure sensor 12, and the screen of the display 11 shows the pressure value of the A-bag 23. During inflation and deflation, medical staff can check the screen of the display 11 to know the pressure change of the A-bag 23.

[0035] Reference Figure 1 This utility model also includes an inflatable balloon 31, which is equipped with an air supply tube 33 and a deflation valve 32. The inflatable balloon 31 can refer to the existing blood pressure cuff balloon. The air supply tube 33 is connected to the inflation port 3. Medical staff can inflate the balloon 31 by squeezing the inflation port 3 and deflate the balloon 3 by opening the deflation valve 32. The pressure of the balloon 23 can be adjusted as needed, and the operation is simple.

[0036] The fixation plate 1 is made of transparent material. After the fixation plate 1 is worn on the wound of the affected limb, medical staff can see the position of the shaping component 2 through the fixation plate 1, which makes it easy to adjust the pressure area of ​​the A-bag 23.

[0037] The strap 13 is lined with elastic sponge, which can relieve the pressure of the strap 13 on the patient's skin and make it more comfortable to wear.
