Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and more particularly to a cardiac surgery nursing compression device. Background Art

[0002] Cardiac surgery nursing compression equipment is an important medical device used to provide patients with timely cardiopulmonary resuscitation in cardiac arrest or other emergency situations. The principle of cardiac compression is mainly to compress the sternum through mechanical pressure to provide continuous cardiopulmonary resuscitation instead of manual chest compression. This compression can increase the intrathoracic pressure, indirectly compress the ventricles, allow blood to flow into the aorta, establish circulation, and create conditions for the recovery of the heart's autonomous rhythm. This principle is based on the "heart pump theory" and the "thoracic pump theory", both of which play a certain role in external chest compression.

[0003] Existing cardiac surgical care compression equipment usually includes an air pump, an output rod, a compression plate and other structures. When the patient's heart needs to be compressed, the air pump drives the output rod and the compression plate to reciprocate in the vertical direction, so that the compression plate presses the patient. However, the current compression equipment is not convenient for adjusting the compression distance of the compression plate. Since the body shapes of different patients vary greatly, such as adult patients and infant patients, the required compression distances are different. The current compression equipment is difficult to meet the compression distance requirements of different patients. Summary of the Invention

[0039] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cardiac surgery nursing compression device, comprising a housing 101, characterized in that an air pump 102 is provided in the middle of the housing 101, an output rod 103 is installed at the lower end of the air pump 102, and a pressing plate 104 is provided at the lower end of the output rod 103;

[0040] The output rod 103 is fixedly connected to a disc 201, and the upper end of the disc 201 is fixedly connected to four L-shaped rods 202, and the four L-shaped rods 202 are arranged in a circle. The lower end of the housing 101 is fixedly connected to four gear rods 203, and the lower ends of the four gear rods 203 are fixedly connected to the same first annular plate 204. The lower end of the housing 101 is fixedly connected to four fixing plates 205, and the four fixing plates 205 are symmetrically fixedly connected to two mounting blocks 206 on one side close to each other. The two mounting blocks 206 are fixedly connected to the lower end of the housing 101. A pawl 207 is rotatably connected between the mounting blocks 206, one end of the pawl 207 is inserted into the tooth groove on the gear rod 203, the upper end of the pawl 207 is fixedly connected to a spring piece 208, one side of the spring piece 208 is fixedly connected to the fixed plate 205, one side of the fixed plate 205 is fixedly connected to a first limit block 209, the bottom of the first limit block 209 is in contact with the other end of the pawl 207, and a fine-tuning component 300 for fine-tuning the height of the pressing plate 104 is provided on the housing 101.

[0041] When it is necessary to compress the patient's heart, the air pump 102 is started, so that the air pump 102 drives the output rod 103, and the output rod 103 drives the pressing plate 104 to compress the patient's heart. When it is necessary to adjust the downward pressing distance of the pressing plate 104 according to the different body shapes of different patients, the first circular plate 204 is pulled upward, and the first circular plate 204 drives the gear rod 203 to move upward. Since the lower end of the pawl 207 is arc-shaped and one end of the pawl 207 inserted in the tooth groove of the gear rod 203 can rotate upward, one end of the pawl 207 rotates upward during the continuous upward movement of the gear rod 203, and the pawl 207 leaves its position. The tooth groove of the gear rod 203, under the elastic force of the spring piece 208, causes the pawl 207 to be inserted into the tooth groove of the next gear rod 203 to restrict the pawl 207 again. After the adjustment of the pressing plate 104 is completed, since the L-shaped rod 202 is fixedly connected to the disc 201, when the pressing plate 104 presses the patient's heart, the air pump 102 drives the L-shaped rod 202 downward through the output rod 103, so that the L-shaped rod 202 contacts the top of the first circular ring plate 204 after the height is adjusted. This position is the maximum distance that the L-shaped rod 202 and the pressing plate 104 have dropped, thereby adjusting the pressing distance of the pressing plate 104.

[0042] like Figure 2 and Figure 4As shown, four first rectangular blocks 210 are fixedly connected to the lower end of the shell 101, and a rectangular groove 211 is opened in the middle of the four first rectangular blocks 210. The inner wall of the rectangular groove 211 is slidably connected with a first moving block 212, and a first spring 213 is fixedly connected between the inner top wall of the rectangular groove 211 and the first moving block 212. The lower end of the first moving block 212 is fixedly connected with a connecting rod 214, and the connecting rod 214 slides through the lower end of the first rectangular block 210. The connecting rod 214 slides through the spring piece 208, and the lower end of the connecting rod 214 contacts the pawl 207. One side of the first moving block 212 is fixedly connected with a first connecting shaft 215, and one side of the four first connecting shafts 215 are fixedly connected with a connecting plate 216, and the lower ends of the four connecting plates 216 are fixedly connected to the same second circular ring plate 217.

[0043] When it is necessary to release the restriction on the gear rod 203, the second annular plate 217 is pulled, and the second annular plate 217 drives the four connecting plates 216 at the same time, so that the connecting plates 216 drive the first connecting shaft 215, and the first connecting shaft 215 drives the first moving block 212, so that the first spring 213 is compressed, and the first moving block 212 drives the connecting rod 214 to leave the pawl 207, thereby releasing the restriction on the gear rod 203.

[0044] like Figure 5 As shown, the fine-tuning assembly 300 includes a fine-tuning plate 301, the cross-section of the fine-tuning plate 301 is a right-angled trapezoid, the fine-tuning plate 301 is arranged at the upper end of the first circular plate 204, and the lower end of the fine-tuning plate 301 is fixedly connected to four sliding rods 302, the four sliding rods 302 are arranged in a circle, and the sliding rods 302 slide through the first circular plate 204, and four push rods 303 are arranged on the outside of the fine-tuning plate 301, and the four push rods 303 all slide through the corresponding gear rods 203, one end of the four push rods 303 is against the inclined surface of the fine-tuning plate 301, and the other end of the four push rods 303 is fixedly connected to the second limit block 304, and a circular shell 305 is slidably provided on the outside of the first circular plate 204, and a limit groove 306 that cooperates with the four second limit blocks 304 is opened in the middle of the circular shell 305.

[0045] After the first circular plate 204 is roughly adjusted to the appropriate height, the pressing plate 104 needs to be fine-tuned. Press the circular shell 305 downward so that the circular shell 305 pushes the four push rods 303 to move toward the middle. The push rods 303 drive the second limit block 304 to slide in the limit groove 306. The push rods 303 can push the fine-adjusting plate 301 to move upward, so that the L-shaped rod 202 can only move downward to the position of the fine-adjusting plate 301, thereby accurately adjusting the descending height of the pressing plate 104.

[0046] like Figure 5As shown, a rubber ring 218 is fixedly connected to the outer surface of one of the gear rods 203, a threaded rod 219 is threadedly connected to the circular shell 305, a screw block 220 is fixedly connected to one side of the threaded rod 219, and a rubber block 221 is fixedly connected to the other side of the threaded rod 219, and the rubber block 221 and the rubber ring 218 are in contact with each other.

[0047] When the circular shell 305 needs to be restricted, the screw block 220 is screwed so that the screw block 220 drives the threaded rod 219, and the threaded rod 219 drives the rubber block 221. The rubber block 221 and the rubber ring 218 fit closely with each other, which can increase friction and thus restrict the circular shell 305.

[0048] like Figure 6 As shown, the upper end of the pressing plate 104 is fixedly connected with a connecting column 222, the upper end of the connecting column 222 is fixedly connected with a fan-shaped block 223, the lower end of the disc 201 is provided with a circular groove 224, the middle part of the disc 201 is fixedly connected with a fan-shaped plate 225, the fan-shaped block 223 is attached to the top of the fan-shaped plate 225 and is located in the circular groove 224, the connecting column 222 is inserted in the circular groove 224, and a fixing component 400 for fixing the pressing plate 104 is provided on the disc 201.

[0049] When the pressing plate 104 needs to be installed, the fan-shaped block 223 is placed in the circular groove 224, and then the pressing plate 104 is rotated so that the pressing plate 104 drives the connecting column 222, and the connecting column 222 drives the fan-shaped block 223 to rotate to the top of the fan-shaped plate 225, thereby completing the installation of the pressing plate 104.

[0050] like Figure 7 As shown, the fixing assembly 400 includes a U-shaped block 401, which is fixedly connected to the lower end of the disc 201. A moving groove 402 is provided in the middle of the U-shaped block 401, and a second moving block 403 is slidably connected to the inner wall of the moving groove 402. A second spring 404 is fixedly connected between the inner wall of the moving groove 402 and the second moving block 403. One side of the second moving block 403 is fixedly connected to a second connecting shaft 405, which slides through one end of the U-shaped block 401, and the second spring 404 is sleeved on the outside of the second connecting shaft 405. The end of the second connecting shaft 405 away from the second moving block 403 is fixedly connected to a handle 406, and the other side of the second moving block 403 is fixedly connected to a limiting rod 407. The connecting column 222 is provided with a socket 408 that cooperates with the limiting rod 407.

[0051] When the pressing plate 104 needs to be disassembled, the handle 406 is pulled, and the handle 406 drives the second connecting shaft 405, so that the second connecting shaft 405 drives the second moving block 403, the second spring 404 is compressed, and the second moving block 403 simultaneously drives the limiting rod 407 to leave the socket 408 on the connecting column 222. Then, the user rotates the pressing plate 104 in the opposite direction to remove the pressing plate 104 from the disc 201. When the pressing plate 104 needs to be installed, the user rotates the pressing plate 104 to install the pressing plate 104 on the disc 201, and then releases the handle 406. The second spring 404 rebounds. Under the elastic force of the second spring 404, the second moving block 403 drives the limiting rod 407 to be inserted into the socket 408 on the connecting column 222 to limit the connecting column 222.

[0052] like Figure 8 As shown, a cross bar 226 is provided at the upper end of the housing 101 , a T-shaped slider 227 is fixedly connected to the upper end of the housing 101 , and a first T-shaped slot 228 that cooperates with the T-shaped slider 227 is provided in the middle of the cross bar 226 .

[0053] When the position of the patient's heart and the pressing plate 104 is relatively offset, the staff needs to adjust the pressing plate 104. The staff pulls the outer shell 101, and through the guiding effect of the first T-shaped slide groove 228, the T-shaped slider 227 drives the outer shell 101 to move, and the outer shell 101 drives the pressing plate 104 to adjust to the position of the patient's heart, so that the pressing plate 104 can press the patient's heart.

[0054] like Figure 8 As shown, the bed is symmetrically slidably connected to a support rod 229, and the left and right ends of the cross bar 226 are fixedly connected to a connecting block 230. A rectangular opening 231 is opened in the middle of the connecting block 230, and the connecting block 230 slides through the support rod 229.

[0055] When the height of the device needs to be adjusted, the crossbar 226 is pulled to slide on the support rod 229. The crossbar 226 drives the housing 101 to adjust the height of the pressing plate 104 to accommodate patients of different sizes.

[0056] like Figure 1 and Figure 8 As shown, the left and right ends of the bed are fixedly connected with slide rails 232, the lower end of the support rod 229 is provided with a second T-shaped slide groove 233 that cooperates with the slide rail 232, and the cross bar 226 and the support rod 229 are both provided with a limiting component 500.

[0057] When the device is in use, the support rod 229 is pulled so that the second T-shaped slot 233 on the support rod 229 slides on the slide rail 232. The support rod 229 drives the cross bar 226 so that the cross bar 226 drives the device to move to the position facing the patient's chest cavity, thereby facilitating compression of the patient.

[0058] like Figure 1 and Figure 9 As shown, the limiting assembly 500 includes three second rectangular blocks 501, one of the second rectangular blocks 501 is fixedly connected to one side of the cross bar 226, and two of the second rectangular blocks 501 are fixedly connected to the front end of the support rod 229 symmetrically up and down, and a sliding groove 502 is opened in the middle of the three second rectangular blocks 501, and a sliding block 503 is slidably connected to the inner wall of the sliding groove 502, and a third spring 504 is fixedly connected between the inner wall of the sliding groove 502 and the sliding block 503, and one end of the sliding block 503 is fixedly connected It is connected to a pull block 505, and a pin 506 is fixedly connected to the side of the sliding block 503 away from the third spring 504. The pin 506 slides through the middle of the T-shaped slider 227, and a plurality of first slots 507 that cooperate with the pin 506 are provided on the cross bar 226. A plurality of second slots 508 that cooperate with the pin 506 are provided on the support rod 229. A plurality of third slots 509 that cooperate with the pin 506 are provided on the slide rail 232. The pin 506 slides through the front end of the connecting block 230.

[0059] When the housing 101 needs to be adjusted, the pull block 505 is pulled, and the pull block 505 drives the sliding block 503, so that the third spring 504 is compressed, and the sliding block 503 simultaneously drives the pin 506 to leave the first slot 507, the second slot 508 or the third slot 509. Then, the user adjusts the housing 101. After the adjustment is completed, the pull block 505 is released, and the third spring 504 rebounds. Under the action of the elastic force of the third spring 504, the sliding block 503 drives the pin 506 to be inserted into the first slot 507, the second slot 508 or the third slot 509 for re-restriction.

[0060] The working process of the technical solution provided by the present invention is as follows:

[0061] When in use, when it is necessary to position the pressing plate 104, first pull the pull block 505, the pull block 505 drives the sliding block 503, so that the third spring 504 is compressed, and the sliding block 503 simultaneously drives the latch 506 to leave the first slot 507, the second slot 508 or the third slot 509, and then pull the support rod 229, so that the second T-shaped slide 233 on the support rod 229 slides on the slide rail 232, slides to the appropriate position, and releases the pull block. 505, the third spring 504 rebounds, and under the elastic force of the third spring 504, the sliding block 503 drives the pin 506 to be inserted into the third slot 509, restricting the support rod 229, and then pulling the shell 101. The shell 101 slides on the cross bar 226 through the T-shaped slider 227 and the first T-shaped slot 228, slides to a suitable position, and releases the pulling block 505, so that the pin 506 is inserted into the first slot 507, restricting the shell 101.

[0062] When the height of the device needs to be adjusted, pull the cross bar 226 to make it slide on the support rod 229 to a suitable position, release the pull block 505, and insert the pin 506 into the second slot 508 to restrict the cross bar 226 to adjust the position of the pressing plate 104. After the adjustment is completed, start the air pump 102 to make the air pump 102 drive the output rod 103, and the output rod 103 drives the pressing plate 104 to press the patient's heart.

[0063] When it is necessary to adjust the downward pressure distance of the pressing plate 104 according to the different body shapes of different patients, the first circular plate 204 is pulled upward, and the first circular plate 204 drives the gear rod 203 to move upward. Since the lower end of the pawl 207 is arc-shaped and one end of the pawl 207 inserted in the tooth groove of the gear rod 203 can be rotated upward, one end of the pawl 207 rotates upward during the continuous upward movement of the gear rod 203, and the pawl 207 leaves the tooth groove of the gear rod 203 where it is located. Under the elastic force of the spring piece 208, the pawl 207 is inserted into The pawl 207 is restricted again in the tooth groove of the next gear rod 203. After the adjustment of the pressing plate 104 is completed, since the L-shaped rod 202 is fixedly connected to the disc 201, when the pressing plate 104 presses the patient's heart, the air pump 102 drives the L-shaped rod 202 downward through the output rod 103, so that the L-shaped rod 202 contacts the top of the first circular ring plate 204 after the height is adjusted. This position is the maximum distance that the L-shaped rod 202 and the pressing plate 104 can descend, thereby adjusting the pressing distance of the pressing plate 104.

[0064] When the restriction on the gear rod 203 needs to be released, the second annular plate 217 is pulled, and the second annular plate 217 drives the four connecting plates 216 at the same time, so that the connecting plate 216 drives the first connecting shaft 215, and the first connecting shaft 215 drives the first moving block 212, so that the first spring 213 is compressed, and the first moving block 212 drives the connecting rod 214 to leave the pawl 207, thereby releasing the restriction on the gear rod 203. When the first annular plate 204 is roughly adjusted to the appropriate height and the pressing plate 104 needs to be fine-tuned, the circular shell 305 is pressed downward, so that the circular shell 305 pushes the four The push rod 303 moves toward the middle, and the push rod 303 drives the second limit block 304 to slide in the limit groove 306. The push rod 303 can push the fine adjustment plate 301 to move upward, so that the L-shaped rod 202 can only move downward to the position of the fine adjustment plate 301, and then the screw block 220 is twisted, so that the screw block 220 drives the threaded rod 219, and the threaded rod 219 drives the rubber block 221. The rubber block 221 and the rubber ring 218 fit closely with each other, which can increase friction and limit the circular shell 305, thereby completing the precise adjustment of the descending height of the pressing plate 104.

[0065] When the pressing plate 104 needs to be replaced, the handle 406 is first pulled, and the handle 406 drives the second connecting shaft 405, so that the second connecting shaft 405 drives the second moving block 403, the second spring 404 is compressed, and the second moving block 403 simultaneously drives the limiting rod 407 to leave the socket 408 on the connecting column 222, and then the pressing plate 104 is rotated, and the pressing plate 104 drives the connecting column 222 and the sector block 223 to rotate, so that the sector block 223 rotates away from the top of the sector plate 225, so that the sector block 223 can be removed from the circular groove 224. Take it out to disassemble the pressing plate 104 from the disc 201. When the pressing plate 104 needs to be installed, the sector block 223 is inserted into the circular groove 224, and then the pressing plate 104 is rotated to rotate the sector block 223 to the top of the sector plate 225, and then the handle 406 is released, and the second spring 404 rebounds. Under the elastic force of the second spring 404, the second moving block 403 drives the limiting rod 407 to be inserted into the socket 408 on the connecting column 222 to limit the connecting column 222, thereby realizing quick replacement of the pressing plate 104.
