Description

Technical Field

[0001] This invention relates to the field of respiratory equipment technology for cardiovascular surgery, specifically a respiratory device for cardiovascular surgical intensive care units. Background Technology

[0002] Cardiovascular surgical respiratory equipment refers to devices used to assist or replace the patient's respiratory function during cardiovascular surgery or treatment. These devices typically include ventilators, extracorporeal membrane oxygenation (ECMO), etc. They provide mechanical ventilation support to help patients maintain normal respiratory function, ensuring the smooth progress of surgery or the effectiveness of treatment. The main function of these devices is to maintain or improve the patient's gas exchange and ventilation functions, ensuring that the lungs can inhale sufficient oxygen and expel carbon dioxide, thereby maintaining the patient's basic vital signs. Cardiovascular surgical respiratory equipment plays a vital role in cardiac surgery and the treatment of heart disease. They not only maintain the patient's vital signs but also promote the patient's recovery and improve their quality of life.

[0003] Currently, existing ventilators used in intensive care units (ICUs) typically only assist patients with breathing. However, because the trachea of ​​these devices lacks a fixed positioning function, it is prone to displacement during assisted breathing, which can lead to accidental compression of the trachea. This significantly impacts the patient's breathing and oxygenation process, causing serious harm. Furthermore, the use of these devices makes it difficult to administer medications to patients with controlled breathing, especially when the patient is agitated or resistant, potentially hindering the progress of treatment. Summary of the Invention

A support frame is fixedly connected to the inner top wall of the monitoring bed, and two multi-stage electric telescopic rods are fixedly connected to the inner bottom wall of the support frame. An arm restraint frame is fixedly connected to the telescopic end of each multi-stage electric telescopic rod, and each arm restraint frame is slidably connected to the monitoring bed. A servo motor is fixedly connected to the monitoring bed, and a second threaded rod is fixedly connected to the output end of the servo motor. The second threaded rod is rotatably connected to the monitoring bed, and a lifting frame is threadedly connected to the second threaded rod. The lifting frame is slidably connected to the monitoring bed, and two push blocks are fixedly connected to the lifting frame. A leg restraint frame is fixedly connected to both push blocks, and the leg restraint frame is slidably connected to the inner wall of the monitoring bed.

[0008] Preferably, the bottom surface of the base plate is fixedly connected to four casters, and handles are fixedly connected to the opposite sides of the two baffles.

[0009] Preferably, the monitoring bed has two reinforcing blocks fixedly connected to both the front and back sides, and the bottom surface of each reinforcing block is fixedly connected to the upper surface of the base plate.

[0010] Preferably, the inner wall of the monitoring bed is fixedly connected to a partition plate, the back of the partition plate is fixedly connected to the front of the limiting box, and the bottom surface of the partition plate is fixedly connected to the upper surface of the base plate.

[0011] Preferably, the front of the partition plate is fixedly connected to two fixing frames, the outer surface of each fixing frame is fixedly connected to the inner wall of the monitoring bed, and the bottom surface of each fixing frame is fixedly connected to the upper surface of the base plate.

[0012] Preferably, each of the fixed frames has a storage frame slidably connected to its inner wall, and a first pull block is fixedly connected to the side of each of the two storage frames that are far apart from each other.

[0013] Preferably, the bottom surface of the monitoring bed is fixedly connected to two reinforcing strips, and the upper surface of each reinforcing strip is fixedly connected to the bottom surface of the baffle.

[0014] Preferably, the inner wall of the limiting box is slidably connected to an opening and closing plate, and a second pull block is fixedly connected to the left side of the opening and closing plate.

[0015] Preferably, two first magnets are fixedly connected to the upper surface of the opening and closing plate, and two second magnets are fixedly connected to the inner top wall of the monitoring bed.

[0016] Preferably, each set of worm gears has a rotating block fixedly connected to one end of each worm gear that is far apart from the other, and each rotating block has anti-slip grooves arranged at equal intervals on its outer surface.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] First, this invention, by setting up a limiting frame, a lifting block, a first threaded rod, a worm gear, and a worm, achieves the following: when the operator manually rotates the worm, the worm's rotation drives the worm gear to rotate. During the rotation of the worm gear, the first threaded rod inside rotates, thereby driving the lifting block and the limiting component above the lifting block to rise. This facilitates adjustment of the device's limiting height as needed, improving the flexibility of the device when limiting the breathing tube. By setting up a slider, spring, fixing frame, and limiting wheel, the movement of the fixing frame can drive the bottom slider and limiting wheel to move to both sides. During the movement of the slider, the spring can be squeezed, thereby opening the two limiting wheels, making it easy to place the breathing tube inside for limiting. At the same time, the spring can facilitate the return of the limiting wheels to their original position, preventing the breathing tube from easily shifting during use.

[0019] Secondly, this invention, by setting up a support frame, multi-stage electric telescopic rods, and an arm restraint frame, allows the multi-stage electric telescopic rods to extend and raise the arm restraint frame to a suitable height, facilitating the placement of the patient's arm. The multi-stage electric telescopic rods also adjust the arm restraint frame to the appropriate height, thus restraining the patient's arm and preventing agitation from affecting treatment. Furthermore, by setting up a servo motor, a second threaded rod, a lifting frame, a push block, and a leg restraint frame, the rotation of the servo motor drives the second threaded rod to rotate, which in turn drives the lifting frame to rise. As the lifting frame rises, it pushes the push block and leg restraint frame to the appropriate height, facilitating the placement of the patient's leg. The servo motor then adjusts the leg restraint frame to the appropriate position, ensuring convenient restraint of the patient's leg. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] Please see Figure 1-6 A breathing device for a cardiovascular surgical intensive care unit includes a base plate 1, with a limiting mechanism 2 and a restraint mechanism 3 disposed above the base plate 1;

[0030] The limiting mechanism 2 includes a monitoring bed 201, the bottom surface of which is fixedly connected to the upper surface of the base plate 1. A ventilator body 202 is fixedly connected to the inner wall of the monitoring bed 201. The bottom surface of the ventilator body 202 is fixedly connected to the upper surface of the base plate 1. A limiting box 204 and a limiting frame 203 are fixedly connected to the upper surface of the base plate 1. A lifting block 205 is slidably connected to the inner wall of each limiting frame 203. A first threaded rod 206 is threadedly connected to the inner wall of each lifting block 205. The bottom end of each first threaded rod 206 is rotatably connected to the inner wall of the limiting frame 203. Worm gears 207 are fixedly connected to the outer surface of each worm gear 207. A worm 208 is meshed with the outer surface of each worm gear 207. The outer surface of each worm 208 is rotatably connected to the inner wall of the limiting frame 203. Two sliders 209 are slidably connected to the inner wall of each lifting block 205. Three springs 212 are fixedly connected to the side of each set of sliders 209 that are far apart from each other. The end of each set of springs 212 that is far apart from each other is fixedly connected to the inner wall of the lifting block 205. A fixing frame 210 is fixedly connected to the upper surface of each slider 209. Two limiting wheels 211 are rotatably connected to the outer surface of each fixing frame 210.

[0031] The monitoring bed 201 has two reinforcing blocks 6 fixedly connected to both the front and back. The bottom surface of each reinforcing block 6 is fixedly connected to the upper surface of the base plate 1. By setting the reinforcing blocks 6, the stability of the monitoring bed 201 can be further increased, enabling it to be in a stable working state.

[0032] The inner wall of the monitoring bed 201 is fixedly connected to a partition plate 7. The back of the partition plate 7 is fixedly connected to the front of the limiting box 204, and the bottom surface of the partition plate 7 is fixedly connected to the upper surface of the base plate 1. By setting the partition plate 7, the area at the bottom of the monitoring bed 201 can be separated, thereby facilitating different operations.

[0033] Two fixed frames 8 are fixedly connected to the front of the partition plate 7. The outer surface of each fixed frame 8 is fixedly connected to the inner wall of the monitoring bed 201, and the bottom surface of each fixed frame 8 is fixedly connected to the upper surface of the base plate 1. By setting the fixed frames 8, a fixed platform can be provided for the storage components, so that medical devices can be stably stored.

[0034] Each fixed frame 8 has a storage frame 10 slidably connected to its inner wall. Each of the two storage frames 10 has a first pull block 11 fixedly connected to its opposite side. By setting up the storage frame 10 and the first pull block 11, it is convenient for staff to store some frequently used small instruments. At the same time, the first pull block 11 can easily pull the moving rod of the storage frame 10.

[0035] The bottom surface of the monitoring bed 201 is fixedly connected to two reinforcing strips 9. The upper surface of each reinforcing strip 9 is fixedly connected to the bottom surface of the baffle 301. By setting the reinforcing strips 9, the stability of the baffle 301 can be further increased, preventing separation during use.

[0036] The inner wall of the limiting box 204 is slidably connected to an opening and closing plate 12, and a second pull block 13 is fixedly connected to the left side of the opening and closing plate 12. By setting the opening and closing plate 12 and the second pull block 13, the opening and closing plate 12 can open and close the limiting box 204, which facilitates the operation of the internal breathing trachea.

[0037] Two first magnets 16 are fixedly connected to the upper surface of the opening and closing plate 12, and two second magnets 17 are fixedly connected to the inner top wall of the monitoring bed 201. By setting the first magnets 16 and the second magnets 17, it is convenient to fix the opening and closing plate 12 after it is opened, so as to prevent the opening and closing plate 12 from automatically resetting during operation.

[0038] Each set of worm gears 208 has a rotating block 14 fixedly connected to one end of each other. Each rotating block 14 has anti-slip grooves 15 arranged at equal intervals on its outer surface. By setting the rotating block 14 and the anti-slip grooves 15, it is convenient for workers to rotate the worm gear 208 by rotating the rotating block 14. At the same time, the anti-slip grooves 15 can prevent the hand from slipping.

[0039] The specific implementation method of this embodiment is as follows: First, the operator turns on the power supply of the ventilator body 202, then opens the opening and closing plate 12 through the second pull block 13, and then connects one end of the breathing tube to the ventilator body 202. Subsequently, the other end of the breathing tube passes through one side of the limiting box 204 and out the other side. Under the action of the limiting box 204, the excess length of the breathing tube can be placed inside it to prevent the excessively long breathing tube from being stepped on or squeezed. Then, the operator rotates the worm gear 208. When the operator manually rotates the worm gear 208, the rotation of the worm gear 208 can drive the worm wheel 207 to rotate. During the rotation of the worm wheel 207, it can drive the first threaded rod 206 inside to rotate. Thus, under the action of the rotation of the first threaded rod 206, the lifting block 205 and the limiting block above the lifting block 205 can be driven. The components are raised until they are adjusted to a suitable height. Then, the staff manually moves the two fixing brackets 210 to both sides. The movement of the fixing brackets 210 can drive the bottom sliders 209 and limiting wheels 211 to move to both sides. During the movement of the sliders 209, the springs 212 can be squeezed, thereby opening the two limiting wheels 211. This makes it easier to place the breathing tube inside and limit it. Then, the fixing brackets 210 are released, and the springs 212 can easily reset the limiting wheels 211, preventing the breathing tube from easily shifting during use. At the same time, the limiting wheels 211 can rotate, so when the length of the breathing tube is too short after limiting, the breathing tube can be pulled directly to move and extend it, making it easier for the patient to wear and breathe oxygen. Finally, the ventilator body 202 can be turned on to start breathing.

[0040] Example 2

[0041] Please see Figure 1-6 The restraint mechanism 3 includes two baffles 301. The sides of the two baffles 301 that are close to each other are fixedly connected to the front and back of the monitoring bed 201, respectively. A support frame 302 is fixedly connected to the inner top wall of the monitoring bed 201. Two multi-stage electric telescopic rods 303 are fixedly connected to the inner bottom wall of the support frame 302. An arm restraint frame 304 is fixedly connected to the telescopic end of each multi-stage electric telescopic rod 303. The outer surface of each arm restraint frame 304 is slidably connected to the inner wall of the monitoring bed 201. A servo motor 30 is fixedly connected to the inner wall of the monitoring bed 201. 5. The output end of the servo motor 305 is fixedly connected to a second threaded rod 306. The top end of the second threaded rod 306 is rotatably connected to the inner wall of the monitoring bed 201. The outer surface of the second threaded rod 306 is threadedly connected to a lifting frame 307. The outer surface of the lifting frame 307 is slidably connected to the inner wall of the monitoring bed 201. The upper surface of the lifting frame 307 is fixedly connected to two push blocks 308. The upper surfaces of the two push blocks 308 are jointly fixedly connected to a leg restraint frame 309. The outer surface of the leg restraint frame 309 is slidably connected to the inner wall of the monitoring bed 201.

[0042] Four casters 5 are fixedly connected to the bottom surface of the base plate 1, and handles 4 are fixedly connected to the opposite sides of the two baffles 301. By setting the casters 5 and handles 4, the device can be easily pushed to move, thereby facilitating the adjustment of the device's position.

[0043] The specific implementation method of this embodiment is as follows: First, the staff connects the power supply to the servo motor 305 and the multi-stage electric telescopic rod 303. When it is necessary to administer medication to the patient and the patient is agitated and uncooperative, the staff activates the multi-stage electric telescopic rod 303 and the servo motor 305. The extension of the multi-stage electric telescopic rod 303 can drive the arm restraint frame 304 to rise until it reaches a suitable height, thus facilitating the placement of the patient's arm inside. The multi-stage electric telescopic rod 303 adjusts the arm restraint frame 304 to a suitable height, thereby restraining the patient's arm. The rotation of the servo motor 305 can drive the second threaded rod 306 to rotate. Under the action of the rotation of the second threaded rod 306, the lifting frame 307 can be driven to rise. When the lifting frame 307 rises, it can push the push block 308 and the leg restraint frame 309 to rise until they reach a suitable height, thus facilitating the placement of the patient's leg inside. The servo motor 305 adjusts the leg restraint frame 309 to a suitable position, thus facilitating the restraint of the patient's leg and preventing the patient's agitation from affecting the treatment.

[0044] The working principle of this invention is as follows: First, the operator connects the power supply to the servo motor 305, the ventilator body 202, and the multi-stage electric telescopic rod 303. Then, the opening and closing plate 12 is opened via the second pull block 13. Next, one end of the breathing tube is connected to the ventilator body 202. Subsequently, the other end of the breathing tube passes through one side of the limiting box 204 and exits through the other side. Under the action of the limiting box 204, excess length of the breathing tube can be placed inside, preventing the excessively long breathing tube from being stepped on or squeezed. Then, the operator rotates the worm gear 208. When the operator manually rotates the worm gear 208, the rotation of the worm gear 208 drives the worm wheel 207 to rotate. During the rotation of wheel 207, the internal first threaded rod 206 is driven to rotate. This rotation of the first threaded rod 206 drives the lifting block 205 and the limiting component above it to rise until a suitable height is reached. Then, the operator manually moves the two fixing brackets 210 to both sides. This movement of the fixing brackets 210 causes the bottom slider 209 and limiting wheel 211 to move to both sides. During the movement of the slider 209, the spring 212 is compressed, opening the two limiting wheels 211. This facilitates the placement and limiting of the breathing tube. Then, the fixing brackets 210 are released, and the spring 212... The limiting wheel 211 allows for easy reset, preventing the trachea from shifting during use. The limiting wheel 211 is also rotatable, allowing for easy extension of the trachea when it is too short after limiting, facilitating patient comfort and oxygen supply. The ventilator body 202 can then be activated for operation. When medication needs to be administered and the patient is agitated or uncooperative, the operator activates the multi-stage electric telescopic rod 303 and servo motor 305. The extension of the multi-stage electric telescopic rod 303 raises the arm restraint frame 304 to a suitable height, allowing for easy placement of the patient's arm. The arm restraint frame 304 is placed inside, and the arm restraint frame 304 is adjusted to an appropriate height by the multi-stage electric telescopic rod 303, thereby restraining the patient's arm. The rotation of the servo motor 305 drives the second threaded rod 306 to rotate, and the rotation of the second threaded rod 306 drives the lifting frame 307 to rise. When the lifting frame 307 rises, it pushes the push block 308 and the leg restraint frame 309 to rise until they reach a suitable height, so that the patient's leg can be easily placed inside. The leg restraint frame 309 is adjusted to an appropriate position by the servo motor 305, which can easily restrain the patient's leg and prevent the patient from agitating and affecting the treatment.
