Description

Technical Field

[0001] The present invention relates to the field of medical technology, and more particularly to an emergency surgical compression hemostasis device. Background Art

[0002] At the emergency treatment site, when a patient suffers severe trauma and the wound is bleeding critically, medical staff often use compression hemostasis as the first step. By applying external force, the blood vessels in the wound are forced to close to achieve the purpose of hemostasis. However, some surgical wounds are complex and often contain various foreign objects such as glass fragments, sand and gravel particles, and metal debris. When using ordinary compression hemostasis devices, since they cannot accurately avoid foreign objects, during the pressure application process, it is very easy for foreign objects to sink deeper into the tissue, cutting surrounding blood vessels and nerves, or causing the wound to tear and expand, causing secondary damage. This secondary damage will not only increase the patient's pain, but may also lead to a significant increase in the risk of wound infection, prolong the wound healing cycle, and even affect the recovery of limb function. In severe cases, it can endanger the patient's life and health. In view of this, we propose an emergency surgical compression hemostasis device. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention uses a specially designed hemostatic flap, which consists of an outer protective plate and multiple folding plates. It can flexibly adjust the central gap area that does not compress foreign objects according to the presence and size of foreign objects in the wound. When treating ordinary trauma, it can directly compress the wound to stop bleeding; when treating wounds with foreign objects, it can accurately avoid foreign objects and prevent the displacement of foreign objects from causing secondary damage to the wound, meeting the hemostasis needs of different wounds and solving the problem that hemostatic devices cannot adapt to the compression of wounds with foreign objects.

[0018] 2. The present invention also connects multiple rotating rods through universal joints and cooperates with the angle adjustment structure. Rotating the adjustment head can drive multiple rotating sleeves to rotate synchronously, thereby realizing the linked compression of the outer guard plate and the folding plate. By controlling the rotation angle, the contact area between the latex layer and the outer edge of the skin is adjusted, making the compression area and position more precise, improving the hemostatic effect, and further solving the problem that the hemostatic device cannot adapt to the compression of the wound with foreign objects.

[0019] 3. The present invention also uses the suction port and opening and closing contact pins on the latex layer, and utilizes the flexible deformation of the latex layer and the opening and closing contact pins when the patient breathes to produce an extrusion and suction effect, thereby sucking blood into the suction cavity. The design of the concave arc surface can avoid blood reflux, effectively reduce blood accumulation in the wound, and reduce the risk of infection.

[0020] 4. The present invention also uses the hemostasis auxiliary structure inside the outer protective plate. By pressing the medical inflatable ball, gas is input into the hollow shell, pushing the movable piston to move. The gas impacts the blood guide groove and guides the blood into the suction port. When the movable piston returns to its position, the liquid inlet check valve generates a suction force, sucking the blood into the hollow shell and discharging it into the liquid storage device through the discharge valve port. In addition, the cold air ejected during the pressing process can be used to apply a cold compress to the wound to relieve the patient's pain.

[0021] 5. The wound encirclement of the present invention is made of rubber material, which has a certain degree of curvature and can fit closely to the skin of the chest, abdomen and other parts. The fixing belt is fixed by Velcro, which is simple and quick to operate, making it convenient for medical staff to quickly complete the installation and fixation of the device in an emergency, thereby buying precious treatment time for patients.

[0039] like Figures 1 to 10As shown, the present invention relates to an emergency surgical compression hemostasis device, which is mainly used in the chest, abdomen or back area of the upper body to deal with common injuries such as punctures and gunshot wounds. It can also be used in areas with little bending such as arms and thighs, and includes a wound enclosure 1, which is made of rubber material. The rubber material gives it a certain degree of bending to adapt to the skin of the chest and abdomen area, a sealing cover 2 is movably installed on the top of the wound enclosure 1, and a flexible tenon rod is installed at the bottom of the sealing cover 2. The tenon rod is combined with the interference fit to achieve the installation of the sealing cover 2. The sealing cover 2 mainly surrounds the wound enclosure 1 to play a dust-proof and shielding effect. Fixing belts 3 are connected to both sides of the wound enclosure 1, and the fixing belts 3 are adhered and fixed by means of Velcro or the like. A cavity part is provided inside the wound enclosure 1, and a plurality of rotating rods 4 are rotatably connected to the cavity part. A rotating sleeve 6 is fixed on the outer periphery of the rotating rod 4. A plurality of hemostatic flaps 7 are provided on one side of the rotating sleeve 6. The plurality of hemostatic flaps 7 form a complete circle. The hemostatic flap 7 is composed of an outer guard plate 701 and a plurality of folding plates 70 2 composition, multiple folding plates 702 are mainly used to adapt to the adjustment of different foreign bodies, and can adjust the gap area in the center that does not oppress the foreign body according to the size of the foreign body, and a folding connector 8 is provided between adjacent sides, and the outer guard plate 701 and the multiple folding plates 702 are folded and connected in sequence through the folding connector 8, and a latex layer 10 is bonded to one side of the blood pressure flap 7, and the folding connector 8 includes an inner slide 801, an inner slide 801, and a central axis of the inner slide 801 is limited and slides with the inner wall of the adjacent outer guard plate 701 or the folding plate 702, and both sides of the inner slide 801 The sides are movably hinged with side panels 802, and the other ends of the two side panels 802 are rotatably connected with a fixed seat 803, and the fixed seat 803 is fixed to one side of the adjacent folding plate 702. The inner sliding seat 801, the side panel 802 and the fixed seat 803 are fitted with the adjacent outer guard plate 701 and folding plate 702 in an interference fit. The fixed seat 803 is provided with a straight-faced limiting end. After being matched into a circle, the mutual close constraints between the multiple blood-stopping flaps 7 can play a stabilizing role. The outer guard plate 701 and the upper halves of the multiple folding plates 702 are all equipped with built-in magnetic attractors.

[0040] Working principle: When treating common trauma hemostasis, directly press the wound encirclement 1 to the wound area, and then use the fixing belt 3 with Velcro to stick it tightly. The combination of the wound encirclement 1 and the multiple hemostatic flaps 7 can achieve the hemostatic effect.

[0041] When it is necessary to stop bleeding from a wound with foreign matter, after rotating the rotating sleeve 6, pull out the folding plate 702 at the corresponding position, bend it and fix it with the magnetic force of the magnetic iron so that the gap area in the center that does not compress the foreign matter matches the foreign matter. At this time, fix the fixing belt 3 to complete the compression and hemostasis of the wound without compressing the foreign matter.

[0042] In order to achieve stable synchronous adjustment and adjustment of the compression area, multiple rotating rods 4 are distributed in a circular array with the wound encirclement 1 as the center. The multiple rotating rods 4 are all made of flexible engineering plastics. Universal joints 5 are connected between the adjacent ends of the multiple rotating rods 4. An angle adjustment structure 9 is provided on the outer periphery of one of the rotating sleeves 6. The angle adjustment structure 9 includes a worm gear 901. The worm gear 901 is a semicircular ring structure. The inner wall of the worm gear 901 is fixed to the outer periphery of the rotating sleeve 6. A worm 902 is meshed with the outer periphery of the worm gear 901. The top of the worm gear 902 penetrates the wound encirclement 1 and is connected to an adjustment head 903. The top of the adjustment head 903 is engraved with an indicator head, and the part of the wound encirclement 1 at the adjustment head 903 is engraved with a rotation angle mark.

[0043] Working principle: Rotate the adjusting head 903 to drive the worm 902 to rotate, and then the worm wheel 901 rotates. Since the inner wall of the worm wheel 901 is fixed to the outer periphery of the rotating sleeve 6, the rotating sleeve 6 can be rotated, and then through the cooperation of multiple rotating rods 4 and multiple universal joints 5, linkage can be achieved, and multiple rotating sleeves 6 can be rotated synchronously, and the outer protective plate 701 and multiple folding plates 702 can be further pressed against the wound. Through the different rotation angles, the latex layer 10 can gradually expand the contact area with the outer edge of the skin, realize the adjustment of the compression area and fix the position, and at the same time, with the help of the indicator head and the rotation angle mark, the adjustment angle can be adjusted.

[0044] In order to achieve the suction of blood, a suction port is provided on the latex layer 10, and an opening and closing contact pin 11 is provided inside the suction port. A plurality of blood guide grooves 12 are connected to one side of the suction port of the latex layer 10. The opening and closing contact pin 11 includes a plurality of arc contact pins 111. The plurality of arc contact pins 111 are annular structures with increasing proportions. The arc contact pins 111 are made of flexible material. When the arc contact pins 111 are squeezed, extrusion sealing can be achieved. The top and bottom of the arc contact pins 111 are both concave arc surfaces 1110. The plurality of arc contact pins 111 are fixed to the inner wall of the suction port, and the cross-section of the suction port is a pointed cone structure.

[0045] Working principle: When the device is installed in the chest and abdominal area, the patient's breathing, combined with the flexible material design of the latex layer 10 and the opening and closing contact feet 11, when the patient inhales, will squeeze the latex layer 10 and the opening and closing contact feet 11, and the internal space of the multiple arc contacts 111 will be squeezed, and when exhaling, the internal space of the multiple arc contacts 111 will relax. In the process, a squeezing and then suctioning effect is generated, which can draw blood into the suction chamber, and combined with the concave arc design of the concave arc surface 1110, it can achieve closure to prevent blood reflux.

[0046] In order to enhance the suction of blood pressure, a hemostasis auxiliary structure 13 is installed inside the outer guard plate 701. The hemostasis auxiliary structure 13 comprises a hollow shell 131 and a movable piston 132. The movable piston 132 moves back and forth along the inside of the hollow shell 131 and performs pumping. The hemostasis auxiliary structure 13 also includes a return spring 133. The return spring 133 is located between the movable piston 132 and the inner top wall of the hollow shell 131. The outer periphery of the movable piston 132 is adapted to the inner wall of the hollow shell 131. A discharge check valve 134 is installed in the center of the movable piston 132. The top of the hollow shell 131 is connected to a liquid inlet check valve 135 connected to the suction port. The bottom of the hollow shell 131 is provided with a check valve 134. It is equipped with an air inlet check valve 136, and the outer periphery of the hollow shell 131 is connected to multiple air outlet check valves 137. The air outlet check valve 137 is connected to a hose or air guide groove connected to the blood guide groove 12. The air outlet end of the hose or air guide groove is arranged to be inclined toward the suction port. Multiple air inlet check valves 136 are connected to an external medical inflatable ball through a main and branch hose. The medical inflatable ball is directly purchased and can automatically recover when pressed. The bottom of the hollow shell 131 is connected to a drain valve port 14. The drain valve port 14 is an openable and closable design. The drain valve port 14 is connected to an external liquid storage device through a main and branch hose. The liquid storage device is a bag or shell that can hold liquid.

[0047] Working principle: When the patient's wound area is bleeding heavily, the liquid storage device and the medical inflatable ball are connected through the main and branch pipes. After the installation is completed, the medical inflatable ball is pressed, and the gas is input into the hollow shell 131 through the air inlet check valve 136. Due to the instantaneous input of gas, the movable piston 132 moves (the instantaneous input air pressure is relatively large). When the movable piston 132 moves to cross the air outlet check valve 137, the gas is discharged through it to the hose or the air guide groove. And through the inclined design, the gas will impact the blood guide groove 12. It also plays the role of guiding the blood input into the suction port. After the gas is input once, the return spring 133 drives the movable piston 132 to return to its original position. During the return process, air will be sucked in. At this time, the liquid inlet check valve 135 generates a suction force to attract the blood inside the suction port. After the blood enters the upper half, it will fall to the lower half through the discharge check valve 134, and then cooperate with the discharge valve port 14 to pass through the main and branch pipes to connect the blood input to the liquid storage device. By pressing the medical inflatable ball back and forth as mentioned above, blood can be sucked.

[0048] It is worth mentioning that during the pressing process, the input gas can also spray cold air to the wound area, acting as a cold compress on the wound and reducing the patient's pain.

[0049] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
