Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically a head compression tourniquet. Background Technology

[0002] During craniotomy in neurosurgery, the head is rich in blood vessels, and the amount of bleeding from head injuries is relatively greater than that from the limbs or trunk. After cutting open the patient's scalp, scalp clips are needed to fix the cut scalp in order to stop the bleeding and fix it. Alternatively, a tourniquet can be applied to the top of the patient's head before surgery to compress and stop the bleeding.

[0003] Patent CN114533184A discloses a head surgery compression hemostat, comprising a fixed part, a movable part, and a compression part. The fixed part and the movable part constitute upper and lower fixing components surrounding the head. The compression part applies pressure to the top of the patient's head for hemostasis on the inner side of the fixed part and the movable part. The fixed part has a jawbone support on its strap and an auxiliary strap behind it. The fixed part is fixed to the head by the strap, auxiliary strap, and head ring, which helps maintain hemostasis, reduces the fatigue of medical staff, and does not interfere with the surgeon's operation. The movable part has a longitudinal arc-shaped rod and a transverse arc-shaped rod that rotate around the fixed part. The compression part on the movable part can be positioned at any position of the head required for the surgery. The compression part is slidably connected to the movable part. The compression part has an air bladder, a flexible ring seat, and a compression ring inside the ring frame. The air bladder pushes the flexible ring seat and the compression ring to conform to any curvature of the head through the inflation tube, achieving the purpose of applying pressure for hemostasis at any position required for head surgery.

[0004] The aforementioned device uses an inflation tube to push the flexible ring seat and compression ring to conform to any curvature of the head, achieving the effect of applying pressure to stop bleeding at any position required during head surgery. A craniotomy typically lasts two to six hours. When blood vessels are compressed for a long time, it can lead to prolonged ischemia at the skin edge. If the compression position cannot be automatically changed during surgery, more cells will die. As the number of necrotic cells increases, complete thrombosis can occur in the blood vessels of the skin flap. Postoperatively, problems such as increased wound edema and hair follicle damage may also occur. Furthermore, manually changing the compression position can easily lead to massive bleeding from the wound, and it cannot adaptively adjust the pressure according to the gradual decrease in head circumference from bottom to top, which can easily lead to problems of excessive or insufficient pressure after changing the compression position. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a head compression tourniquet to solve the problems mentioned in the background section, such as thrombosis and hair follicle necrosis caused by prolonged compression of the same location, and the inability to adaptively adjust the compression force according to head circumference.

[0008] Preferably, each of the rotating gears meshes with a corresponding linkage rack, and the linkage gear meshes with a plurality of connecting columns.

[0009] Preferably, each of the adjusting and pressurizing mechanisms includes a triangular block, a rotating shaft, and four adjusting and pressurizing components. The rotating shaft is rotatably disposed at the center of the linkage gear, and the triangular block is fixedly disposed at the end of the rotating shaft. Each adjusting and pressurizing component includes a connecting plate, a U-shaped rod, a first wedge block, a second wedge block, a limiting rod, and an adjusting spring. The limiting rod is movably inserted into the side wall of the corresponding one-way valve, the adjusting spring is sleeved on the limiting rod, the second wedge block is fixedly disposed at the end of the limiting rod, the connecting plate is fixedly disposed at the side wall of the corresponding pressure plate, the first wedge block is fixedly disposed at the other end of the connecting plate, and the U-shaped rod is fixedly disposed at the side wall of the pressure belt.

[0010] Preferably, each of the connecting plates is slidably engaged with the corresponding U-shaped rod.

[0011] Preferably, the sidewall of the second wedge block abuts against the triangular block, and the sidewall of the first wedge block abuts against the other sidewall of the second wedge block.

[0012] Preferably, the top of the protective casing is provided with a cable outlet.

[0013] Preferably, the gas flow direction of each of the one-way valves is from top to bottom.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention achieves the hemostatic effect while automatically switching the patient's compression position by setting up a triangular block, a rotating shaft, a connecting plate, a U-shaped rod, a first wedge block, a second wedge block, a limiting rod and an adjusting spring. This avoids many problems such as blood vessel adhesion, end tissue necrosis and inability to grow hair caused by continuous compression of the same position during a craniotomy that lasts for several hours. Furthermore, the pressure relief valve allows for adaptive adjustment of the inflation volume to different head circumferences when switching the auxiliary airbag, thereby maintaining the same pressure on the head regardless of how the auxiliary airbag is switched. This avoids both insufficient pressure causing massive bleeding from the wound and excessive pressure causing blood vessel blockage and thrombosis.

[0016] (2) By setting up a rotating gear, a linkage motor, a long rod, a spring column, a linkage spring, a linkage rack, a connecting column, a mounting plate, an annular groove, a rotating roller, a suture, and a linkage gear, this invention achieves the automatic stopping of the cyclic inflation of the auxiliary airbag during suturing, thus avoiding excessive bleeding during suturing and increasing the difficulty of suturing.

[0017] (3) The present invention uses a pressure plate, a triangular block, a connecting plate, a U-shaped rod, a first wedge block, a second wedge block, a limiting rod and an adjusting spring to squeeze and deliver the gas inside the auxiliary airbag to the next auxiliary airbag. This avoids the situation where the gas delivery of the previous auxiliary airbag is incomplete when switching auxiliary airbags, which would result in insufficient pressure in the next auxiliary airbag and ensures the hemostasis effect after switching auxiliary airbags.

[0029] 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.

[0030] Please see Figure 1-10One embodiment of the present invention provides a head compression tourniquet, comprising a compression band 1, wherein a plurality of annular main adjusting airbags 10 are disposed on the inner sidewall of the compression band 1, and the plurality of main adjusting airbags are interconnected; a main inflation tube 9 is disposed on the sidewall of the compression band 1; six auxiliary airbags 7 are disposed between every two main adjusting airbags 10; a pressure relief three-way valve 4 is disposed at the top of the six auxiliary airbags 7; an auxiliary connecting tube 2 is disposed between the six pressure relief three-way valves 4; an auxiliary inflation tube 3 is disposed on the sidewall of the auxiliary connecting tube 2; and C-shaped supports are disposed at the upper and lower ends of the auxiliary airbags 7. The auxiliary airbag 7 is provided with a one-way valve 15 between its upper and lower gaps in the tube 14. Each one-way valve 15 is provided with a pressure relief valve 17 on its side wall. A manifold 11 is provided between every three pressure relief valves 17. Each manifold 11 is connected to the corresponding C-shaped tube 14. Each auxiliary airbag 7 is provided with an adjusting pressurization mechanism 5 on its side wall. Each auxiliary airbag 7 is provided with a pressure plate 13 on its top. Each adjusting pressurization mechanism 5 is provided with a linkage mechanism 6 on its side. Each adjusting pressurization mechanism 5 and linkage mechanism 6 is provided with a protective shell 8 on its outer wall. First, the device is placed above the patient's brow bone. Then, air is injected into the main regulating airbag 10 through the main inflation tube 9 to initially clamp the patient's head. Next, air is injected into the top auxiliary airbag 7 through the auxiliary inflation tube 3. Excess air is released using the pressure relief three-way valve 4, thereby adjusting the pressure of the top auxiliary airbag 7 on the head. The craniotomy can then proceed. During the craniotomy, the linkage mechanism 6 drives the adjusting pressure mechanism 5, and the one-way valve 15 and pressure plate 13 work together to adjust the pressure inside the top auxiliary airbag 7. The gas is delivered downwards sequentially. Based on the characteristic that the circumference of the human head gradually increases from top to bottom, excess gas is discharged to the manifold through the pressure relief valve 17 set on the side wall of the corresponding one-way valve 15. The gas is then delivered back to the auxiliary airbag 7 at the top through the manifold. When the patient's scalp needs to be sutured at the end of the operation, the linkage mechanism 6 is activated by pulling the suture 611. The linkage mechanism 6 disengages, causing the pressure adjustment mechanism 5 to stop working. This avoids excessive bleeding and increased difficulty in suturing 611 due to the switching of the auxiliary airbag 7 during suturing 611.

[0031] Specifically, each of the linkage mechanisms 6 includes a rotating gear 61, a linkage motor 62, a long rod 63, a spring column 64, a linkage spring 65, a linkage rack 66, several connecting columns 67, a mounting plate 68, an annular groove 69, a rotating roller 610, a sewing thread 611, and a linkage gear 612. The mounting plate 68 is fixedly mounted on the outer wall of the compression belt 1. The annular groove 69 is disposed on the mounting plate 68. The linkage motor 62 is slidably mounted on the back side of the mounting plate 68 along the annular groove 69, and the output shaft of the linkage motor 62 is located within the annular groove 69. The linkage gear 612... The rotating roller 610 is rotatably mounted on the inner wall of the protective shell 8, and the stitching 611 is mounted on the surface of the rotating roller 610. The rotating gear 61 is fixedly mounted on the end of the rotating roller 610. Several connecting posts 67 are movably inserted into the mounting plate 68. The long rod 63 is fixedly mounted on the back of several connecting posts 67. One end of the linkage rack 66 is fixedly mounted on two of the connecting posts 67. The spring post 64 is fixedly mounted on the other end of the linkage rack 66. The linkage spring 65 is sleeved on the spring post 64. The rotation of the output shaft of the linkage motor 62 drives the linkage gear 612 to rotate. The rotation of the linkage gear 612 abuts against the connecting column 67, thereby driving the linkage motor 62 to move in a circular motion along the annular groove 69. In conjunction with the adjusting pressure mechanism 5, the gas inside the auxiliary airbag 7 is gradually delivered to the corresponding auxiliary airbag 7. At the end of the operation, when suturing 611 is required on the scalp, the suture 611 is pulled out, thereby driving the rotating roller 610 to rotate. The rotation of the rotating roller 610 drives the rotating gear 61 to rotate. The rotation of the rotating gear 61 drives the linkage rack 66 to move towards the connecting column 67. At this time, the connecting column 67 is compressed, causing the long rod 63 and all the connecting columns 67 to move into the mounting plate 68. At this time, the linkage gear 612 can no longer abut against the connecting column 67 and cannot move, thereby causing the adjusting pressure mechanism 5 to stop adjusting. This achieves the automatic stopping of the cyclic inflation of the auxiliary airbag 7 when suturing 611, avoiding excessive bleeding during suturing 611 and increasing the difficulty of suturing 611.

[0032] Specifically, each of the rotating gears 61 meshes with a corresponding linkage rack 66, and the linkage gear 612 meshes with a plurality of connecting posts 67.

[0033] Specifically, each of the adjusting and pressurizing mechanisms 5 includes a triangular block 57, a rotating shaft 58, and four adjusting and pressurizing components. The rotating shaft 58 is rotatably mounted at the center of the linkage gear 612, and the triangular block 57 is fixedly mounted at the end of the rotating shaft 58. Each adjusting and pressurizing component includes a connecting plate 51, a U-shaped rod 52, a first wedge block 53, a second wedge block 54, a limiting rod 55, and an adjusting spring 56. The limiting rod 55 is movably inserted into the side wall of the corresponding one-way valve 15, and the adjusting spring 56 is sleeved on the limiting rod 55. The second wedge block 54 is fixedly mounted at the end of the limiting rod 55. The connecting plate 51 is fixedly mounted on the side wall of the corresponding pressure plate 13, the first wedge block 53 is fixedly mounted at the other end of the connecting plate 51, and the U-shaped rod 52 is fixedly mounted on the side wall of the pressure belt 1. The downward movement of the rotating shaft 58 causes the triangular block 57 to move downward. The triangular block 57, moving downward, abuts against the second wedge block 54 and moves towards the first wedge block 53. The movement of the second wedge block 54 causes the limiting rod 55 to move synchronously. The moving limiting rod 55 releases the limit on the one-way valve 15, allowing the corresponding one-way valve 15 to normally deliver gas from top to bottom. Simultaneously, the movement of the second wedge block 54 abuts against the first wedge block 53, which is limited downward by the U-shaped rod 52. The movement of the second wedge block 54 also causes the connecting plate 51 to move synchronously, connecting... The movement of plate 51 causes the corresponding pressure plate 13 to move synchronously. The movement of pressure plate 13 compresses the gas in the top auxiliary airbag 7 into the lower auxiliary airbag 7. Based on the characteristic that the circumference of the human head gradually increases from top to bottom, and in conjunction with the setting of pressure relief valve 17, when the amount of gas in the lower auxiliary airbag 7 reaches the pressure value of the previous auxiliary airbag 7 on the head, the corresponding pressure relief valve 17 discharges the excess gas into the manifold 11, and finally delivers it into the C-shaped tube 14. This process continues until the gas in the C-shaped tube 14 is completely discharged. All the gas in the bottom auxiliary airbag 7 is compressed by the pressure plate 13 and delivered to the top auxiliary airbag 7, completing a gas cycle inside the auxiliary airbag 7. This ensures hemostasis while automatically switching the patient's pressure position, avoiding problems such as vascular adhesion, end tissue necrosis, and hair regrowth caused by continuous pressure on the same position during a craniotomy lasting several hours. Furthermore, the pressure relief valve 17 adaptively adjusts the inflation volume to accommodate changes in head circumference at different locations when switching auxiliary airbags 7, ensuring consistent pressure on the head regardless of the airbag 7 position. This prevents both insufficient pressure leading to excessive bleeding and excessive pressure causing vascular blockage and thrombosis. The pressure plate 13 also compresses and delivers gas from the auxiliary airbag 7 to the next auxiliary airbag 7, preventing incomplete gas delivery from the previous auxiliary airbag 7 from affecting the pressure of the next auxiliary airbag 7.

[0034] Specifically, each of the connecting plates 51 is slidably engaged with the corresponding U-shaped rod 52.

[0035] Specifically, the sidewall of the second wedge block 54 abuts against the triangular block 57, and the sidewall of the first wedge block 53 abuts against the other sidewall of the second wedge block 54.

[0036] Specifically, each of the protective shells 8 is provided with a cable outlet 16 at its top.

[0037] Specifically, the gas flow direction of each of the one-way valves 15 is from top to bottom.

[0038] Working principle: First, the device is placed above the patient's brow bone. Then, air is injected into the main regulating airbag 10 through the main inflation tube 9 to initially clamp the patient's head. Next, air is injected into the top auxiliary airbag 7 through the auxiliary inflation tube 3. Excess air is released using the pressure relief three-way valve 4, thereby adjusting the pressure of the top auxiliary airbag 7 on the head. Then, craniotomy can be performed. During the craniotomy, the output shaft of the linkage motor 62 rotates, driving the linkage gear 612 to rotate. The rotation of the linkage gear 612 abuts against the connecting column 67, thereby driving the linkage motor 62 to move in a circular motion along the annular groove 69. The linkage motor 62 drives the rotating shaft 58 to move synchronously. The downward movement of the rotating shaft 58 causes the triangular block 57 to move downward. The triangular block 57 moves downward, contacting the second wedge block 54 and moving towards the first wedge block 53. The movement of the second wedge block 54 causes the limiting rod 55 to move synchronously. The movement of the limiting rod 55 releases the limit of the one-way valve 15, allowing the corresponding one-way valve 15 to normally deliver gas from top to bottom. Simultaneously, the movement of the second wedge block 54 causes it to contact the first wedge block 53, which is limited downward by the U-shaped rod 52. The movement of the second wedge block 54 causes the connecting plate 51 to move synchronously. The movement of the connecting plate 51 causes the corresponding pressure plate 13 to move synchronously. The movement compresses the gas in the top auxiliary airbag 7 into the lower auxiliary airbag 7. Based on the characteristic that the head circumference gradually increases from top to bottom, and in conjunction with the pressure relief valve 17, when the lower auxiliary airbag 7 reaches the pressure value exerted on the head by the previous auxiliary airbag 7, the corresponding pressure relief valve 17 releases excess gas into the manifold 11, ultimately delivering it into the C-tube 14. This process continues until all the gas in the C-tube 14 and the bottom auxiliary airbag 7 is compressed by the pressure plate 13 and delivered to the top auxiliary airbag 7. This completes one gas cycle within the auxiliary airbag 7. Furthermore, at the end of the surgery... When suturing the scalp 611, pulling out the suture 611 drives the rotating roller 610 to rotate. The rotation of the rotating roller 610 drives the rotating gear 61 to rotate. The rotation of the rotating gear 61 drives the linkage rack 66 to move towards the connecting post 67. At this time, the connecting post 67 is squeezed, which drives the long rod 63 and all the connecting posts 67 to move into the mounting plate 68, so that the linkage gear 612 cannot contact the connecting post 67. At this time, the linkage gear 612 cannot move, so the auxiliary airbag 7 will not automatically deliver gas to the next auxiliary airbag 7, ensuring the best hemostasis effect during suturing, minimizing bleeding, and reducing the difficulty of suturing 611.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
