Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a head compression tourniquet. Background Art

[0002] During craniotomy, the head is rich in blood vessels and the amount of bleeding from head trauma is greater than that from the limbs or body. After cutting the patient's scalp, a scalp clamp is needed to fix the patient's cut scalp in order to stop bleeding and fix the scalp. Alternatively, a compression tourniquet can be tied above the patient's brow before the operation to compress the top of the patient's skull to stop bleeding.

[0003] The invention patent with patent number CN114533184A discloses a compression hemostat for head surgery, comprising a fixed part, a movable part and a compression part, wherein the fixed part and the movable part constitute an upper and lower fixed part surrounding the head, and the compression part compresses and stops bleeding on the top of the patient's head on the inner sides of the fixed part and the movable part; a jaw support is provided on the fixed part strap, and an auxiliary strap is provided behind the strap, which is surrounded and fixed on the head by the fixed part strap, the auxiliary strap and the head ring to assist in maintaining the hemostasis state, reduce the fatigue of medical staff, and do not interfere with the surgeon's operation; the movable part is provided with a longitudinal arc rod and a transverse arc rod rotating around the fixed part, and the compression part on the movable part is placed at any position of the head required for the operation through the movable part, and the compression part is slidably connected to the movable part, and the compression part is provided with an inflatable bag, a flexible ring seat and a compression ring in the ring frame, and the inflatable bag pushes the flexible ring seat and the compression ring to fit any curvature of the head through the inflation pipeline, so as to achieve the purpose of compression and hemostasis at any position required for the head surgery.

[0004] The above-mentioned device uses the inflation pipeline to enable the inflatable bag to push the flexible ring seat and the compression ring to fit any curvature of the head, so as to achieve the effect of compression and hemostasis at any position required for head surgery. A craniotomy usually lasts two to six hours, and the human body's blood vessels will cause long skin ischemia time when under long-term compression. If the compression position cannot be automatically changed during the operation, more cells will die.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-10An embodiment of the present invention is as follows: a head compression tourniquet, comprising a compression belt 1, wherein the inner side wall of the compression belt 1 is provided with a plurality of annular main regulating air bags 10, and the plurality of active regulating air bags are interconnected, the side wall of the compression belt 1 is provided with a main inflation tube 9, six auxiliary air bags 7 are provided between every two main regulating air bags 10, a pressure relief three-way valve 4 is provided on the top of the six auxiliary air bags 7, an auxiliary connecting tube 2 is provided between the six pressure relief three-way valves 4, an auxiliary inflation tube 3 is provided on the side wall of the auxiliary connecting tube 2, and C is provided at the upper and lower ends of the auxiliary air bags 7 A one-way valve 15 is provided between the upper and lower gaps of each auxiliary airbag 7, a pressure relief valve 17 is provided on the side wall of each one-way valve 15, a confluence pipe 11 is provided between every three pressure relief valves 17, and each confluence pipe 11 is connected to the corresponding C-shaped tube 14, an adjusting and pressurizing mechanism 5 is provided on the side wall of each auxiliary airbag 7, a pressure plate 13 is provided on the top of each auxiliary airbag 7, a linkage mechanism 6 is provided on the side of each adjusting and pressurizing mechanism 5, and a protective shell 8 is provided on the outer wall of each adjusting and pressurizing mechanism 5 and the linkage mechanism 6. First, wear the device above the patient's eyebrow arch, then flush the gas into the main regulating airbag 10 through the main inflation tube 9 to initially clamp the patient's head, and then flush the gas into the top circle of auxiliary airbags 7 through the auxiliary inflation tube 3, and cooperate with the pressure relief three-way valve 4 to discharge excess gas, so as to adjust the pressure of the top auxiliary airbag 7 on the head, and then perform a craniotomy. During the craniotomy, the linkage mechanism 6 drives the regulating pressurizing mechanism 5 to work, and cooperates with the setting of the one-way valve 15 and the pressure plate 13 to adjust the pressure inside the top auxiliary airbag 7. The gas is transported downwards gradually, and according to the characteristic that the circumference of the human head gradually increases from top to bottom, the excess gas is discharged to the manifold through the pressure relief valve 17 arranged on the side wall of the corresponding one-way valve 15, and the gas is re-transported 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 driven to work by pulling the suture 611, and the linkage mechanism 6 is disengaged, so that the regulating and pressurizing mechanism 5 stops working, thereby avoiding the situation where the switching of the auxiliary airbag 7 during the suture 611 causes excessive bleeding and increases the difficulty of the suture 611.

[0031] Specifically, each linkage mechanism 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, a plurality of connecting columns 67, a mounting plate 68, an annular groove 69, a rotating roller 610, a suture 611 and a linkage gear 612. The mounting plate 68 is fixedly arranged on the outer side wall of the compression belt 1, the annular groove 69 is arranged on the mounting plate 68, the linkage motor 62 is slidably arranged 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 in the annular groove 69. The linkage gear 612 It is arranged at the end of the output shaft of the linkage motor 62, the rotating roller 610 is rotatably arranged on the inner wall of the protective shell 8, the stitching 611 is arranged on the surface of the rotating roller 610, the rotating gear 61 is fixedly arranged at the end of the rotating roller 610, a plurality of the connecting columns 67 are movably plugged on the mounting plate 68, the long rod 63 is fixedly arranged on the back of a plurality of the connecting columns 67, one end of the linkage rack 66 is fixedly arranged on two of the connecting columns 67, the spring column 64 is fixedly arranged on the other end of the linkage rack 66, and the linkage spring 65 is sleeved on the spring column 64. The linkage gear 612 is driven to rotate by the output shaft of the linkage motor 62, and the linkage gear 612 rotates to contact the connecting column 67, thereby driving the linkage motor 62 to perform a circular motion along the annular groove 69, and cooperating with the adjusting and pressurizing mechanism 5 to gradually deliver the gas inside the auxiliary airbag 7 to the corresponding auxiliary airbag 7, and when suturing 611 is required on the scalp at the end of the operation, the suture 611 is pulled out to drive the rotating roller 610 to rotate, and the rotating roller 610 rotates to drive the rotating gear 61 to rotate, and the rotating gear 61 rotates to drive the linkage rack 66 to move toward the connecting column 67. At this time, the connecting column 67 is squeezed to drive the long rod 63 and all the connecting columns 67 to move to the inside of the mounting plate 68. At this time, the linkage gear 612 cannot contact the connecting column 67, and the linkage gear 612 cannot move, so that the adjusting and pressurizing mechanism 5 stops adjusting; it is achieved that the cyclic inflation of the auxiliary airbag 7 can be automatically stopped during the suture 611, so as to avoid heavy bleeding during the suture 611, which increases the difficulty of suture 611.

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

[0033] Specifically, each of the regulating and pressurizing mechanisms 5 includes a triangular block 57, a rotating shaft 58 and four regulating and pressurizing components. The rotating shaft 58 is rotatably set at the center of the linkage gear 612, and the triangular block 57 is fixedly set at the end of the rotating shaft 58. Each of the regulating and pressurizing components 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 in 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 set at the end of the limiting rod 55. The connecting plate 51 is fixedly set on the side wall of the corresponding pressure plate 13. The first wedge block 53 is fixedly set at the other end of the connecting plate 51, and the U-shaped rod 52 is fixedly set on the side wall of the compression belt 1. The downward movement of the rotating shaft 58 drives the triangular block 57 downward, and the downward movement of the triangular block 57 resists the second wedge block 54 and moves toward the first wedge block 53. The movement of the second wedge block 54 drives the limit rod 55 to move synchronously. The movement of the limit rod 55 releases the limit of the one-way valve 15, so that the corresponding one-way valve 15 can normally transport gas from top to bottom, and the movement of the second wedge block 54 will synchronously resist the first wedge block 53 and move downward under the limit of the U-shaped rod 52. The movement of the second wedge block 54 drives the connecting plate 51 to move synchronously, and the connecting plate 51 is connected. The movement of the plate 51 drives the corresponding pressure plate 13 to move synchronously. The movement of the pressure plate 13 presses the gas of the auxiliary airbag 7 at the top into the interior of the auxiliary airbag 7 below. In addition, according to the characteristic that the circumference of the human head gradually increases from top to bottom, the setting of the pressure relief valve 17 is coordinated so that when the gas volume filled into the auxiliary airbag 7 below reaches the pressure value on the head equal to that of the previous auxiliary airbag 7 on the head, the corresponding pressure relief valve 17 discharges the excess gas into the confluence pipe 11, and finally transports it to the interior of the C-type tube 14. By analogy, the gas in the C-type tube 14 is finally discharged. All the gas in the bottom auxiliary airbag 7 is squeezed by the pressure plate 13 and transported to the top auxiliary airbag 7, which completes the gas circulation inside the auxiliary airbag 7; it ensures the hemostatic effect while automatically switching the patient's compression position, avoiding the compression of the same position during a craniotomy lasting several hours, which leads to blood vessel adhesion, end tissue necrosis, inability to grow hair and many other problems; and the setting of the pressure relief valve 17 allows the inflation amount to be adaptively adjusted to the head circumference changes at different positions of the head when the auxiliary airbag 7 is switched, so as to achieve the characteristic of maintaining the same pressure on the head no matter how the auxiliary airbag 7 is switched, and there will be neither insufficient pressure to cause massive bleeding of the wound nor excessive pressure to cause blockage of the patient's blood vessels to form thrombus; and the setting of the pressure plate 13 allows the gas inside the auxiliary airbag 7 to be squeezed and transported to the next auxiliary airbag 7, avoiding the incomplete gas delivery of the previous auxiliary airbag 7 when switching the auxiliary airbag 7, thereby affecting the pressure of the next auxiliary airbag 7.

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

[0035] Specifically, the side wall of the second wedge block 54 is in abutment with the triangular block 57 , and the side wall of the first wedge block 53 is in abutment with the other side wall of the second wedge block 54 .

[0036] Specifically, a wire outlet 16 is provided on the top of each protective shell 8 .

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

[0038] Working principle: First, wear the device above the patient's eyebrow arch, then flush the gas into the main regulating airbag 10 through the main inflation tube 9, so as to initially clamp the patient's head, and then flush the gas into the auxiliary airbag 7 in the top circle through the auxiliary inflation tube 3, and cooperate with the pressure relief three-way valve 4 to discharge the excess gas, so as to adjust the pressure of the top auxiliary airbag 7 on the head, and then perform a craniotomy. During the craniotomy, the linkage gear 612 is driven to rotate by the output shaft of the linkage motor 62, and the linkage gear 612 rotates to resist the connecting column 67, thereby driving the linkage motor 62 to perform a circular motion along the annular groove 69. The linkage motor 62 moves to drive the rotating shaft 58 to move synchronously, and the rotating shaft 58 moves downward to drive the triangular block 57 to move downward. The triangular block 57 moves downward to contact the second wedge block 54 and moves toward the first wedge block 53. The movement of the second wedge block 54 drives the limiting rod 55 to move synchronously. The movement of the limiting rod 55 releases the limit of the one-way valve 15, so that the corresponding one-way valve 15 can normally transport gas from top to bottom, and the movement of the second wedge block 54 will synchronously contact the first wedge block 53 and move downward due to the limit of the U-shaped rod 52. The movement of the second wedge block 54 drives the connecting plate 51 to move synchronously, and the movement of the connecting plate 51 drives the corresponding pressing plate 13 to move synchronously. The movement compresses the gas of the top auxiliary airbag 7 into the interior of the lower auxiliary airbag 7, and according to the characteristic that the circumference of the human head gradually increases from top to bottom, the setting of the pressure relief valve 17 is coordinated, so that when the amount of gas filled into the lower auxiliary airbag 7 reaches the pressure value on the head and the pressure value on the head of the upper auxiliary airbag 7, the corresponding pressure relief valve 17 discharges the excess gas into the confluence pipe 11, and finally transports it to the interior of the C-type tube 14, and so on. Finally, the gas in the C-type tube 14 and all the gas in the bottom auxiliary airbag 7 are squeezed by the pressure plate 13 and transported to the interior of the top auxiliary airbag 7. This is a complete gas cycle inside the auxiliary airbag 7, and it is needed at the end of the operation. When suturing the scalp 611, the suture 611 is pulled out to drive the rotating roller 610 to rotate, and the rotating roller 610 rotates to drive the rotating gear 61 to rotate, and the rotating gear 61 rotates to drive the linkage rack 66 to move toward the connecting column 67. At this time, the connecting column 67 is squeezed to drive the long rod 63 and all the connecting columns 67 to move to the inside of the mounting plate 68, so that the linkage gear 612 cannot contact the connecting column 67. At this time, the linkage gear 612 cannot move, so that the auxiliary airbag 7 will not automatically deliver gas to the next auxiliary airbag 7, thereby ensuring the best hemostatic effect during suturing, minimizing the amount of bleeding, and reducing the difficulty of suturing 611.
