Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, it relates to a device for warming and pressurizing the limbs after shock. Background Technology

[0002] Under the influence of severe pathogenic factors such as severe blood loss, fluid loss, infection, and trauma, the effective circulating blood volume decreases sharply, and tissue blood perfusion is severely insufficient, causing cellular ischemia and hypoxia, leading to systemic critical pathological processes such as functional and metabolic disorders or structural damage to vital organs. Shock is a clinical manifestation of acute circulatory failure, often leading to multiple organ failure, with high morbidity and mortality.

[0003] Shock patients often experience cold extremities due to circulatory failure. Keeping them warm can prevent hypothermia, reduce metabolic consumption, and avoid further vasoconstriction. When warming patients, avoid using hot water bottles directly; instead, maintain body temperature through environmental regulation and warming blankets.

[0004] Existing heating and pressurizing devices cannot monitor the actual temperature of the limbs in real time and provide feedback to medical staff, nor can they automatically adjust the temperature and pressure. Medical staff can only rely on experience to judge whether it is appropriate, which is prone to errors and risks. Moreover, the operation and control methods may be relatively complex, requiring medical staff to spend a lot of time learning and familiarizing themselves with them. In emergencies, this may delay treatment time and affect the timely treatment of patients in shock. In addition, patients in shock usually have severe hypovolemia, and the heart's ejection rate is significantly reduced, resulting in a state of ischemia in the body's tissues and organs. In this case, elevating the lower limbs can promote blood flow back to the heart from the lower limbs, increase the amount of blood returning to the heart, and thus increase the heart's ejection rate, ensuring the blood supply to surrounding vital tissues and organs. Existing devices cannot meet this requirement.

[0005] Therefore, we propose a device for warming and pressurizing the limbs after shock. Utility Model Content

[0006] The purpose of this invention is to provide a device for heating and pressurizing the limbs after shock, in order to solve the above-mentioned technical problems.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1 to 6 As shown, a device for warming and pressurizing limbs after shock includes a housing 1, with a lid 2 connected to the housing 1 via a limiting component. The housing 1 houses an upper limb warming and pressurizing component 23 and a lower limb warming and pressurizing component 22 with identical structures, as well as a main unit 3. The main unit 3 integrates a miniature air pump and a display controller.

[0028] The limiting assembly includes guide plates 4 symmetrically fixed to the inner wall of the housing 1. The guide plates 4 are provided with guide grooves 5, which are Y-shaped and consist of a straight groove and an arc groove communicating with the middle of the straight groove. The guide grooves 5 are slidably connected to a connecting plate 6 fixedly connected to the housing cover 2. The connecting plate 6 is provided with a slide rod slidably connected to the straight groove and a crossbar 7 slidably connected to both the straight groove and the arc groove. The two connecting plates 6 are fixedly connected by the crossbar 7. One end of the crossbar 7 is provided with a connecting rod assembly consisting of two connecting rods 9 rotatably connected at the end. One connecting rod 9 is rotatably connected to the crossbar 7, and the other connecting rod 9 is provided with a knob 8 rotatably connected to the housing 1.

[0029] A positioning assembly is provided between the knob 8 and the connecting rod 9. The positioning assembly includes a driven gear 10 fixedly connected to the connecting rod 9. The driven gear 10 meshes with a driving gear 11 rotatably connected to the housing 1. The driving gear 11 is fixedly connected to the knob 8 on the same axis. A ratchet 12 is provided on the driving gear 11 on the same axis. The housing 1 is provided with a pawl 13 that meshes with the ratchet 12 via a torsion spring.

[0030] The upper limb heating and pressurizing assembly includes an upper limb body 14 that can be rolled up and formed into a sleeve shape by Velcro. The upper limb body 14 is embedded with a heating element 15 and a heat insulation layer 17 and a heat conduction layer 16 covering the top and bottom surfaces of the heating element 15, respectively. The inner wall of the upper limb body 14 is provided with a silicone honeycomb-shaped pad 18. The outer surface of the upper limb body 14 is provided with an airbag 19. The airbag 19 is connected to a miniature air pump in the main unit 3 through a detachable air duct. The heating element is electrically connected to the main unit 3 through a detachable wire.

[0031] The upper limb body 14 includes two heating and pressurizing zones and a joint movement zone distributed in the heating and pressurizing zones. Airbags 19 are distributed in the heating and pressurizing zones. A temperature sensor 20 and a pressure detector 21 are provided on the surface of the pad 18 located in the heating and pressurizing zones.

[0032] Furthermore, it should be noted that the display controller on the main unit 3 can monitor the temperature and pressure of the upper and lower limb heating and pressurization zones in real time via the temperature sensor 20 and pressure detector 21. Regarding the micro-air pump, an intermittent pressurization program (e.g., 10 minutes of pressurization followed by a 5-minute interval) can be set via the display controller to simulate the "muscle pump" effect and promote venous return. The pressure intensity can be automatically adjusted based on the monitored pressure to maintain a mean arterial pressure ≥65 mmHg. The heating element 15 can be a flexible carbon fiber heating element 15, with a temperature range of 35-42℃ set via the display controller. The heating plate can be a corrugated heat-conducting aluminum plate, satisfying both curling requirements and achieving uniform heat dissipation. The contact surface uses a silicone honeycomb-shaped pad 18, satisfying both breathability and achieving uniform pressure distribution.

[0033] Working principle and usage: The patient lies flat on the bed. Rotating knob 8 opens the lid 2, allowing the main unit 3, upper limb heating and pressurizing components, and lower limb heating and pressurizing components 22 to be taken out. First, the upper limb heating and pressurizing components 23 and 22 are fixed to the patient's limbs using Velcro and straps. Connect the air tube and wires, and perform heating and pressurizing operations on the patient through the display controller on the main unit 3. Then, release the pawl 13 from the ratchet 12, rotate knob 8 to drive the drive gear 11 to rotate, which in turn drives the driven gear 10 to rotate. The rotating driven gear 10 drives the connecting rod 9 to rotate. Under the transmission action of the two connecting rods 9, the connecting plate 6 slides along the guide groove 5 and rotates, thereby opening the lid 2 to a suitable tilt angle. The patient's lower limbs can be placed on the lid 2 to achieve the purpose of raising the lower limbs. At this time, the pawl 13 plays a positioning role on the ratchet 12 to ensure that the patient's lower limbs will not fall off the lid 2.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
