Abstract
Description
Technical Field
[0001] This invention relates to the field of hemostasis and emergency treatment technology, and specifically to a hemostasis and emergency treatment device. Background Technology
[0002] Massive hemorrhage and hemorrhagic shock are the leading causes of death after trauma, making emergency treatment of these conditions crucial in the overall care process. The primary goal of on-site first aid is to control massive bleeding, prevent hemorrhagic shock, buy time for subsequent treatment, and create conditions for specialized medical intervention. Current trauma first aid hemostasis measures mainly include hemostasis using hemostatic forceps, tourniquet application, and triangular bandage application.
[0003] Pressure hemostasis can also be achieved using a hemostasis first-aid kit. For example, patent CN212346633U discloses a pressure hemostasis first-aid kit for severe trauma, belonging to the field of medical emergency equipment technology. It addresses the technical problems of existing hemostasis first-aid devices easily causing distal limb ischemia and necrosis, limited bandaging sites, and non-reusability. The kit includes a pressure bag with a hemostatic dressing layer, a pressure-applying layer, and a cable tie fixing buckle. A bandage is fixed inside the cable tie fixing buckle. Inflow and exhaust pipes are fixed to both sides of the pressure bag. The inflow pipe has an expansion tube and a pressure block, and the exhaust pipe has an exhaust knob with a sealing plug at the end. Pressure is applied to the bleeding wound for rapid hemostasis, and the exhaust port releases air to reduce pressure, preventing distal limb ischemia and necrosis during prolonged pressure bandaging. Multiple expansion tubes allow for repeated pressure application, consumables are replaceable, and the kit is reusable. The triangular distribution of the cable tie fixing buckles facilitates bandaging of almost all areas, including the limbs, head, neck, and pelvis.

Therefore, they should not be construed as limitations on this invention.
[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0031] See Figures 1-4The present invention provides an embodiment of a hemostasis and emergency rescue device, comprising: a pressure plate 1, a sliding plate 2, an airbag 3, and a drive mechanism 4; one end of the sliding plate 2 is slidably inserted into the pressure plate 1; further, lugs 11 are respectively installed on opposite sides of the pressure plate 1; thereby enabling ropes to be bound to the lugs 11, and the pressure plate 1 to be fixed by telescoping; further, it also includes a guide rod 12, which is arranged along the sliding direction of the sliding plate 2, the guide rod 12 is fixedly connected to the pressure plate 1, and the guide rod 12 slides through the sliding plate 2; the sliding of the sliding plate 2 is guided by the guide rod 12; the airbag 3 is installed on the pressure plate 1, and one end of the airbag 3 is installed on the sliding plate 2; the drive mechanism 4 can drive the sliding plate 2 to slide.
[0032] In practice, the pressure plate 1 is fixedly installed on the patient's skin by a strap or other object; the sliding plate 2 is driven to slide by the drive mechanism 4, and the sliding plate 2 drives the airbag 3 to extend. In this way, the length of the airbag 3 can be adjusted to adapt to wounds of different sizes. By shortening the length of the airbag 3, the damage to normal skin tissue caused by pressure is effectively reduced, and the airbag 3 can be more easily fitted to the wound position.

[0034] In practice, the air pump 42 operates, drawing gas into the gas channel 41. The gas drives the fan blade 46 to rotate, which in turn drives the rotating shaft 45 to rotate. The rotating shaft 45 then drives the lead screw 43 to rotate, and the lead screw 43 moves the sliding plate 2 via the nut seat 44. When the sliding plate 2 slides to the designated position, the airbag 3 is adjusted to the designated length. At this time, the limiting mechanism 5 operates, driving the rotating shaft 45 to separate from the lead screw 43. This prevents the lead screw 43 from rotating when the rotating shaft 45 rotates.

[0036] In practice, the fan blade 46 drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the lead screw 43 to rotate through the cooperation of the insert piece 51 in the slot 56; the lead screw 43 drives the sliding plate 2 to move through the nut seat 44; when the nut seat 44 abuts against the limiting plate 55, the movement of the nut seat 44 drives the limiting plate 55 to move synchronously, and the limiting plate 55 drives the paddle 53 to move through the connector 54, and the paddle 53 drives the lead screw 43 to move away from the rotating shaft 45 through the disc 52, so that the insert piece 51 separates from the slot 56, thus separating the lead screw 43 from the rotating shaft 45; the rotation of the rotating shaft 45 will not drive the lead screw 43 to rotate; and by adjusting the length of the connector 54, the position of the limiting plate 55 can be adjusted, thereby adjusting the sliding distance of the sliding plate 2 and realizing the limiting of the sliding plate 2.
[0037] See Figures 1-4 In other embodiments, the connector 54 includes a connecting rod 541, a connecting sleeve 542, and a dial 543.

The connecting sleeve 542 is slidably mounted on the nut seat 44 along the straight direction of the connecting sleeve 542. The limiting plate 55 is fixedly mounted on the connecting sleeve 542. The dial 543 is coaxially fixed with the connecting rod 541 and extends to the outside of the pressure plate 1. In specific implementation, the dial 543 is rotated, which drives the connecting rod 541 to rotate. The connecting rod 541 drives the connecting sleeve 542 to move through the thread, thereby adjusting the length of the connector 54 and adjusting the position of the limiting plate 55.
[0038] See Figures 1-4In another embodiment, the airbag 3 is equipped with an air inlet pipe 31 and a mounting plate 32; one end of the air inlet pipe 31 is connected to the airbag 3; the air inlet pipe 31 is threadedly connected to the pressure plate 1, and the other end of the air inlet pipe 31 is connected to the gas channel 41; the lever 53 is detachably connected to the sliding plate 2. In specific implementation, the airbag 3 is detachably mounted on the pressure plate 1 through the thread on the air inlet pipe 31, and the airbag 3 is connected to the gas channel 41 through the air inlet pipe 31, allowing air to be drawn in and out of the airbag 3; one end of the airbag 3 is detachably mounted on the sliding plate 2 through the mounting plate 32; specifically, it is detachably mounted on the sliding plate 2 through Velcro; the air inlet pipe 31 and the mounting plate 32 facilitate the installation and removal of the airbag 3, making it easy to clean and replace the airbag 3.
