Description

Technical Field

[0001] This invention relates to the field of emergency medical device technology, and in particular to a sliding cardiac surgical emergency medical device. Background Technology

[0002] Cardiac surgery is a relatively young branch of surgery, primarily treating heart diseases surgically, such as coronary artery bypass grafting, congenital heart disease surgery, and valve replacement. Common heart diseases treated include congenital heart disease, valvular heart disease, coronary artery disease, aortic aneurysm, pericardial disease, and cardiac tumors.

[0003] In current cardiac surgery, when a patient experiences sudden cardiac arrest, medical staff are required to kneel on the bed and perform chest compressions with their hands together. However, kneeling on the bed can easily cause the medical staff to press on the patient's body, resulting in secondary injury. Furthermore, kneeling on the bed while performing chest compressions can cause the legs to slide to the sides, which can easily exhaust the medical staff. Summary of the Invention

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. The present invention has a reasonable structure. When one end of the fixing rod is fixed, the bolt on the second sleeve is rotated, which facilitates the sliding of the second sleeve on the fixing rod. A third rotating shaft is fixedly connected to the second sleeve, and a linkage plate is rotatably connected to the third rotating shaft. The other end of the linkage plate is rotatably connected to the second rotating shaft of the first sleeve. The movement of the second sleeve pushes the support rod on the first sleeve to rotate around the first rotating shaft through the linkage plate, which facilitates the bottom foot cup of the sleeve on the support rod to be supported on the bed board, thereby facilitating the overall fixing of the fixing rod.

[0017] 2. In this invention, the position of the sleeve rod can be adjusted according to different bed board heights. First, the pull column is pulled upward, and the insertion plate on the movable block is disengaged from the slot by the pull column, which facilitates the up and down movement of the sleeve rod. Then, the limiting plate will slide inside the adjusting block. After the position is determined, the pull column is released, and the insertion plate on the movable block will move downward by the elastic force of the first spring, which facilitates the insertion plate to be inserted into the corresponding slot, thus facilitating the fixation of the position of the sleeve rod.

[0018] 3. In this invention, the base plate is pushed to make the pulley slide on the fixed rod. As the base plate moves, the gear plate rotates on the rack. When the position of the base plate is determined, the handle is turned. The rotation of the handle facilitates the rotation of the cam on the transmission rod, which in turn facilitates the upward movement of the adjustment rod. The upward movement of the adjustment rod causes the locking block on the top block to engage inside the limiting groove on the turntable, which in turn facilitates the driven shaft to stop rotating and fixes the position of the base plate. This makes it convenient for medical personnel to place their legs in the storage slot on the foam pad to perform emergency measures. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] Example: Reference Figure 1 - Figure 8The sliding cardiac surgical emergency device shown includes a clamping plate 1, a fixing post 101 fixedly connected to the top of the clamping plate 1, a docking plate 102 fixedly connected to the top of the fixing post 101, a handle 103 fixedly connected to the middle of the top surface of the docking plate 102, a rubber pad 104 fixedly connected to the inner wall of the clamping plate 1, a threaded rod 105 threadedly connected to the clamping plate 1, a pressure plate 106 fixedly connected to one end of the threaded rod 105, an adjusting head 107 fixedly connected to the other end of the threaded rod 105, a fixing rod 108 fixedly connected to one side of the clamping plate 1, a receiving groove 109 formed on the surface of the fixing rod 108, and a rack 110 fixedly installed inside the receiving groove 109; it also includes a support assembly, a limiting assembly, and an adjusting assembly. The support assembly is set at one end of the fixing rod 108 to fix the overall position of the fixing rod 108, the limiting assembly is set on the support assembly for cooperation, and the adjusting assembly is set on the fixing rod 108 for placing the legs of medical personnel.

[0031] Specifically, the clamping plate 1 is clamped at the foot of the medical bed, and then the adjusting head 107 is rotated. The rotation of the adjusting head 107 drives the threaded rod 105 to rotate, so that the pressure plate 106 can be tightly attached to the foot of the bed for clamping and fixing, which facilitates emergency medical measures.

[0032] In one embodiment of this invention, the support assembly includes a connector 2 fixedly mounted on one end of a fixed rod 108. The connector 2 is fixedly mounted on a connector 201. A first rotating shaft 202 is rotatably connected to the bottom of the connector 201. The first rotating shaft 202 is fixedly connected to a support rod 203. A sleeve 204 is movably inserted into one end of the support rod 203. A foot cup 205 is fixedly connected to the other end of the sleeve 204. A first sleeve 206 is fixedly connected to the middle of the support rod 203. A second rotating shaft 207 is fixedly connected to the outer surface of the first sleeve 206. A linkage plate 208 is rotatably connected to the second rotating shaft 207. The other end of the linkage plate 208 is rotatably connected to a third rotating shaft 209. The third rotating shaft 209 is fixedly connected to a second sleeve 210. The second sleeve 210 is movably sleeved on the fixed rod 108. A bolt 211 is threadedly connected to the second sleeve 210.

[0033] Specifically, when fixing one end of the fixing rod 108, the bolt 211 on the second sleeve 210 is rotated to facilitate the sliding of the second sleeve 210 on the fixing rod 108. A third rotating shaft 209 is fixedly connected to the second sleeve 210, and a linkage plate 208 is rotatably connected to the third rotating shaft 209. The other end of the linkage plate 208 is rotatably connected to the second rotating shaft 207 of the first sleeve 206. The movement of the second sleeve 210 pushes the support rod 203 on the first sleeve 206 to rotate around the first rotating shaft 202 through the linkage plate 208, so that the bottom foot cup 205 of the sleeve rod 204 on the support rod 203 is supported on the bed board, thereby facilitating the overall fixing of the fixing rod 108.

[0034] In one embodiment of this invention, the limiting component includes a fixed base 3 fixedly mounted on the support rod 203. A limiting plate 301 is fixedly connected to one side of the fixed base 3. The top surface of the limiting plate 301 has several sets of slots 302. The limiting plate 301 is slidably connected to the adjusting block 303. The adjusting block 303 is fixedly connected to the surface of the sleeve rod 204. A sliding groove 304 is provided on the adjusting block 303. A slider 305 is slidably connected inside the sliding groove 304. The slider 305 is fixedly connected inside the movable block 306. The bottom of the movable block 306 is fixedly connected to... There is an insert plate 307, the bottom of which is inserted into one of the slots 302. A pull rod 308 is fixedly connected to the top surface of the movable block 306. The pull rod 308 is movably inserted into the middle of the positioning plate 309. Both ends of the positioning plate 309 are fixedly connected to the adjusting block 303. A ring 310 is fixedly connected to the pull rod 308. A first spring 311 is sleeved on the pull rod 308. Both ends of the first spring 311 are fixedly connected to the top surface of the positioning plate 309 and the bottom surface of the ring 310, respectively. A pull post 312 is fixedly connected to the top of the pull rod 308.

[0035] Specifically, the position of the sleeve rod 204 can be adjusted according to different bed board heights. First, the pull column 312 is pulled upwards. The pull column 312 causes the insert plate 307 on the movable block 306 to disengage from the slot 302, thus facilitating the vertical movement of the sleeve rod 204. Then, the limiting plate 301 slides inside the adjusting block 303. After the position is determined, the pull column 312 is released, and the insert plate 307 on the movable block 306 moves downwards due to the elastic force of the first spring 311, thus facilitating the insertion of the insert plate 307 into the corresponding slot 302, thereby facilitating the fixation of the position of the sleeve rod 204.

[0036] In one embodiment of this invention, the adjusting assembly includes a pulley 4 fixedly mounted on a fixed rod 108. The pulley 4 is rotatably connected to a mounting base 401. A docking post 402 is fixedly connected to one side of the mounting base 401. One end of the docking post 402 is fixedly connected to a horizontal plate 403. A support plate 404 is fixedly connected to the middle of one side of the horizontal plate 403. A base plate 405 is fixedly connected to the bottom of the support plate 404. A foam pad 406 is fixedly mounted on the top surface of the base plate 405. A pair of storage slots 407 are provided on the foam pad 406. A bearing seat 5 is fixedly connected to the middle of the other side of the horizontal plate 403. A driven shaft 501 is rotatably connected to the bearing seat 5. A turntable 502 is fixedly connected to one end of the driven shaft 501. A plurality of limit slots 503 are provided on the turntable 502. A geared disc 504 is fixedly connected to the other end of the driven shaft 501. 04 meshes with rack 110. A pair of adjusting rods 505 are movably inserted on the support plate 404. A top block 506 is fixedly connected between the top ends of the pair of adjusting rods 505. A groove is opened on the top surface of the top block 506. A locking block 507 is fixedly connected inside the groove. A pressure block 508 is fixedly connected between the bottom ends of the adjusting rods 505. A second spring 509 is sleeved on the adjusting rods 505. The two ends of the second spring 509 are fixedly connected to the bottom surface of the support plate 404 and the top surface of the pressure block 508, respectively. An abutment block 510 is fixedly connected to the bottom surface of the pressure block 508. An arc groove 511 is opened on the abutment block 510. A cam 512 meshes inside the arc groove 511. The cam 512 is fixedly connected to the transmission rod 513. The middle position of the transmission rod 513 is rotatably connected to the support plate 404. A throttle 514 is fixedly connected to the other end of the transmission rod 513.

[0037] Specifically, by pushing the base plate 405, the pulley 4 slides on the fixed rod 108. As the base plate 405 moves, the gear plate 504 rotates on the rack 110. When the position of the base plate 405 is determined, the handle 514 is rotated. The rotation of the handle 514 facilitates the rotation of the cam 512 on the transmission rod 513, thereby facilitating the upward movement of the adjusting rod 505 as a whole. The upward movement of the adjusting rod 505 causes the locking block 507 on the top block 506 to engage inside the limiting groove 503 on the turntable 502, thereby facilitating the stopping of the driven shaft 501 and fixing the position of the base plate 405. This allows medical personnel to place their legs against the storage slot 407 on the foam pad 406 to perform emergency measures.

[0038] The working principle of this invention is as follows: When one end of the fixing rod 108 is fixed, the bolt 211 on the second sleeve 210 is rotated, which facilitates the sliding of the second sleeve 210 on the fixing rod 108. A third rotating shaft 209 is fixedly connected to the second sleeve 210, and a linkage plate 208 is rotatably connected to the third rotating shaft 209. The other end of the linkage plate 208 is rotatably connected to the second rotating shaft 207 of the first sleeve 206. The movement of the second sleeve 210 pushes the support rod 203 on the first sleeve 206 to rotate around the first rotating shaft 202 through the linkage plate 208, which facilitates the bottom foot cup 205 of the sleeve rod 204 on the support rod 203 to be supported on the bed board, thereby facilitating the overall fixing of the fixing rod 108.

[0039] The position of the sleeve rod 204 can be adjusted according to different bed board heights. First, pull the pull column 312 upward. The pull column 312 causes the insert plate 307 on the movable block 306 to disengage from the slot 302, which facilitates the up and down movement of the sleeve rod 204. Then, the limiting plate 301 slides inside the adjusting block 303. After the position is determined, release the pull column 312. The insert plate 307 on the movable block 306 will move downward by the elastic force of the first spring 311, which facilitates the insertion plate 307 to be inserted into the corresponding slot 302, thus facilitating the fixation of the position of the sleeve rod 204.

[0040] By pushing the base plate 405, the pulley 4 slides on the fixed rod 108. As the base plate 405 moves, the gear plate 504 rotates on the rack 110. When the position of the base plate 405 is determined, the handle 514 is rotated. The rotation of the handle 514 facilitates the rotation of the cam 512 on the transmission rod 513, thereby facilitating the upward movement of the adjusting rod 505 as a whole. The upward movement of the adjusting rod 505 causes the locking block 507 on the top block 506 to engage inside the limiting groove 503 on the turntable 502, thereby facilitating the stopping of the driven shaft 501 and fixing the position of the base plate 405. This allows medical personnel to place their legs against the storage groove 407 on the foam pad 406 to perform emergency measures.
