Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cardiac resuscitation device. Background Technology

[0002] During cardiac surgery, unexpected bleeding from the surgical wound requires immediate hemostasis. Traditionally, this involves medical staff applying pressure with a tourniquet, which not only increases their workload but also wastes valuable time. Therefore, various auxiliary devices are used in cardiac resuscitation procedures.

[0003] For example, Chinese invention patent No. 201810504754.9 provides a hemostasis and resuscitation device for clinical use in cardiology. This device controls a first electric telescopic rod to move a rubber tourniquet up and down, a fourth electric telescopic rod to rotate the tourniquet, and a third electric telescopic rod to move a hemostatic plate up and down to stop bleeding from the patient's wound. However, analysis of the above patent and existing technology reveals that traditional resuscitation devices require repeated adjustments to the height and position of the hemostasis point based on the location of the bleeding, making the operation cumbersome and inconvenient to quickly move the hemostatic block to the area to be stopped, thus leading to delayed hemostasis and affecting resuscitation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a cardiology emergency device to solve the technical problem mentioned in the background art: when using traditional emergency devices to stop bleeding in patients, it is necessary to repeatedly adjust the height and position of the hemostasis according to the location of the hemostasis, which is cumbersome to operate and inconvenient to quickly move the hemostatic block to the area to be stopped, thus resulting in untimely hemostasis and affecting the emergency treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cardiology resuscitation device, comprising a support arm, one end of which is provided with a connecting bed frame connected by a locking mechanism, the support arm being rotatable along a pivot at one end and its position locked by the locking mechanism; the other end of the support arm is provided with a mounting frame, the mounting frame being provided with at least two sets of support cylinders, each support cylinder having a mounting rod passing through it, and an adjustment component being provided within the mounting frame; the support cylinders having windows that allow the adjustment component to engage or disengage from the mounting rods through the windows; one end of each of the two sets of mounting rods is provided with a U-shaped frame, the U-shaped frame having a mounting cylinder rotatably connected by a mounting sleeve, the mounting cylinder having a movable block inside, and the mounting cylinder having a first fixing component limiting the movable block to rotate along the axis of the mounting sleeve and a second fixing component limiting the movable block to rotate on its own axis along the axis of the mounting cylinder; the bottom of the mounting cylinder has a rotatably mounted connecting cylinder, the bottom of the connecting cylinder having a hemostatic block, and a square rod at the bottom of the movable block slidingly passing through the connecting cylinder.

[0006] Preferably, the locking mechanism includes two sets of mounting housings fixedly mounted on the connecting bed frame. The two ends of the rotating shaft pass through the two sets of mounting housings respectively. Each end of the rotating shaft is provided with a ratchet and a spiral spring. One end of the spiral spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the inner side of the mounting housing. A pawl connected by the mounting shaft is provided inside the mounting housing. One end of the pawl is engaged with the ratchet. A first return spring is provided between the pawl and the connecting bed frame. The other ends of the two sets of pawls pass through an opening on one side of the mounting housing and are connected by an opening plate.

[0007] Preferably, the connecting bed frame is provided with two sets of threaded knobs.

[0008] Preferably, the adjustment component includes a toothed block, and multiple evenly arranged fixing slots are provided at the bottom of both sets of mounting rods. The toothed block is engaged in the fixing slots. An inclined frame is provided at the bottom of the toothed block, and a control rod is slidably installed in the inclined frame. A first handle is provided on one side of the control rod and connected by two sets of connecting brackets. The two sets of connecting brackets slide through a shield provided on the mounting frame. A second handle is provided on one side of the shield. Two sets of second return springs are provided between the toothed block and the inner bottom of the mounting frame. There is a gap between the first handle and the second handle.

[0009] Preferably, the two sets of positioning pins at the bottom of the toothed block are respectively inserted into the two sets of positioning cylinders at the bottom of the inner side of the mounting frame, and the two sets of second return springs are respectively sleeved on the two sets of positioning cylinders.

[0010] Preferably, the first fixing component includes a mounting ring sleeved on the movable block, the mounting ring having two sets of connecting posts, one end of each connecting post having a locking block, the connecting post being disposed within the mounting sleeve, the locking block being slidably engaged in a groove opened at one end of the mounting sleeve, the inner side of the U-shaped frame having two sets of internal toothed rings, the mounting sleeve passing through the internal toothed rings, and the locking block being engaged in a groove on the inner side of the internal toothed rings; the mounting cylinder having a cover, the movable block having a handle connected via a connecting rod, the connecting rod having a third return spring sleeved on it, the two ends of the third return spring contacting the movable block and the cover respectively.

[0011] Preferably, the second fixing component includes a first toothed disc fixedly disposed at the bottom of the movable block and a second toothed disc fixedly disposed at the bottom of the inner side of the mounting cylinder, wherein the teeth at the bottom of the first toothed disc are engaged in the tooth grooves opened on the second toothed disc.

[0012] Preferably, the tooth length at the bottom of the first toothed disc is the same as the sliding distance of the locking block within the groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When using this cardiology resuscitation device, the bed frame is fixed to one side of the operating table. When it is necessary to stop bleeding from the patient's wound, one hand can operate the adjustment component to release the fixation of the two sets of mounting rods, while the other hand can simultaneously release the first and second fixing components, allowing the mounting rods to slide within the two sets of support cylinders. The lateral position of the mounting cylinders is adjusted, moving them above the wound. The first fixing component controls the rotation of the mounting cylinder along the mounting sleeve and fixes its position, allowing adjustment of the lateral tilt angle of the hemostatic block according to the wound location. The second fixed component controls the rotation of the movable block and fixes its position. During the rotation of the movable block, the square rod drives the hemostatic block to rotate along the axis of the connecting cylinder and fixes its position. The angle of the hemostatic block can be adjusted according to the specific location of the wound. Finally, the support arm is pressed down to rotate along the axis, so that the hemostatic block can compress the wound to stop bleeding. Under the action of the locking mechanism, the position of the support arm is fixed, so as to quickly stop the bleeding of the wound without cumbersome adjustment operations, improve the hemostasis efficiency in cardiology emergency treatment, and save rescue time to the greatest extent.

[0015] 2. When operating the adjustment assembly, simply grip the first and second handles with one hand to slide the control rod laterally within the mounting bracket. Through its interaction with the inclined frame, the toothed block moves downwards a certain distance until it disengages from the fixing slot, releasing the two sets of mounting rods. The other hand can then use the operating handle to slide the mounting rod within the support cylinder, adjusting the lateral position of the hemostatic block to quickly move it above the wound. During the downward movement of the toothed block, the second return spring is compressed. After adjustment, release the first and second handles; the return spring's restoring force will then control the toothed block to move upwards and re-engage in the corresponding fixing slot, securing the mounting rod. This operation allows for rapid and significant adjustment of the hemostatic block's position according to the lateral position of the wound, improving the efficiency of cardiology emergency care.

[0016] 3. When operating the first and second fixing components, lifting the handle upwards moves the movable block upwards within the mounting cylinder. During this movement, the movable block, via the mounting ring, moves the connecting column upwards within the mounting sleeve, causing the locking block to retract into the sliding groove and disengage from the inner groove of the internal toothed ring. This allows the mounting cylinder to rotate along the axis of the mounting sleeve, adjusting the angle of the hemostatic block according to the wound angle. Simultaneously lifting the handle upwards causes the movable block to move upwards, disengaging the first toothed disc from the second toothed disc. Rotating the handle then rotates the movable block within the mounting ring, allowing the hemostatic block to rotate along the axis of the connecting cylinder through the interaction of the square rod and the connecting cylinder. This adjusts the hemostasis position according to the longitudinal position of the wound, further improving hemostasis efficiency and range, thereby enhancing the efficiency of cardiology emergency care.

[0027] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0028] Example:

[0029] like Figures 1 to 5As shown, the present invention provides a cardiology resuscitation device, including a support arm 101. One end of the support arm 101 is provided with a connecting bed frame 105 connected by a locking mechanism. The support arm 101 can rotate along a pivot 102 at one end and its position is locked by the locking mechanism. The locking mechanism includes two sets of mounting housings 106 fixedly mounted on the connecting bed frame 105. Both ends of the pivot 102 are respectively inserted into the two sets of mounting housings 106. Both ends of the pivot 102 are provided with ratchet 1. 03 and spiral spring 104, one end of spiral spring 104 is fixedly connected to rotating shaft 102, and the other end is fixedly connected to the inside of mounting housing 106. The mounting housing 106 is provided with pawl 108 connected by mounting shaft 107. One end of pawl 108 is locked on ratchet 103. A first return spring 110 is provided between pawl 108 and connecting bed frame 105. The other ends of the two sets of pawl 108 pass through the opening on one side of mounting housing 106 and are connected by opening plate 109.

[0030] The support arm 101 can be pressed down to rotate the shaft 102. During rotation, the shaft 102 drives the ratchet 103 to rotate, causing the spiral spring 104 to deform. The ratchet 103, in turn, pushes the pawl 108 along the mounting shaft 107 via its inclined surface. The pawl 108, under the action of the first return spring 110, remains locked onto the ratchet 103, fixing its position. During movement, the support arm 101 presses the hemostatic block 602 at one end of the device downwards until it contacts the patient's wound. Once fixed, the hemostatic block 602 does not spring back, improving stability during hemostasis. When hemostasis is no longer needed, the opening plate 109 can be pushed upwards to rotate the pawl 108 along the mounting shaft 107 and disengage it from the ratchet 103. The return force of the spiral spring 104 causes the shaft 102 to reverse, lifting the support arm 101 to quickly relieve pressure and stop the bleeding.

[0031] like Figure 3 , 4As shown, in this embodiment, a mounting frame 201 is provided at the other end of the support arm 101. Support cylinders 202 are provided on both sides of the inner wall of the mounting frame 201. A set of mounting rods 203 passes through every two sets of support cylinders 202. An adjustment component is provided inside the mounting frame 201. The mounting rods 203 can move within the support cylinders 202 and their positions can be fixed by the adjustment component. The adjustment component includes toothed blocks 205. Multiple sets of evenly arranged fixing grooves 204 are provided at the bottom of both sets of mounting rods 203. The toothed blocks 205 are engaged in the fixing grooves 204. The bottom of the toothed blocks 205 is provided with... A slanted frame 206 is provided, and a control lever 301 is slidably installed inside the slanted frame 206. A first grip 303 is provided on one side of the control lever 301 and connected by two sets of connecting brackets 302. The two sets of connecting brackets 302 are slidably installed inside a shield 307 provided on the mounting frame 201. A second grip 308 is provided on one side of the shield 307. Two sets of second return springs 306 are provided between the toothed block 205 and the bottom inner side of the mounting frame 201. There is a gap between the first grip 303 and the second grip 308 to provide space for the movement of the first grip 303.

[0032] When the lateral position of the hemostatic block 602 needs to be adjusted according to the location of the wound, one hand can grip the first handle 303 and the second handle 308 to close them. During the movement of the first handle 303, the two sets of connecting frames 302 slide within the shield 307, thereby causing the control rod 301 to move horizontally. Since the two sets of positioning pins 304 at the bottom of the toothed block 205 are respectively inserted into the two sets of positioning cylinders 305 at the bottom of the inner side of the mounting frame 201, the movement of the toothed block 205 is positioned by the cooperation of the positioning pins 304 and the positioning cylinders 305, so that it can only move up and down. During the movement, the control rod 301 applies a downward force to the inclined frame 206 by cooperating with the inclined surface of the inclined frame 206, causing the toothed block 205 to move downward until the toothed block 205 disengages from the fixing groove 204. Then, the other hand can be used to control the mounting rod 203 to move within the support cylinder 202 to adjust the lateral position of the hemostatic block 602. Furthermore, during the downward movement of the toothed block 205, the two sets of second return springs 306 are compressed. After the position of the hemostatic block 602 is adjusted, the first handle 303 and the second handle 308 are released. Under the reset force of the second return springs 306, the toothed block 205 can be re-engaged into the fixing groove 204, thus completing the fixation of the mounting rod 203 and the hemostatic block 602. The lateral position adjustment of the hemostatic block 602 is relatively convenient and quick, thereby improving the efficiency of hemostasis.

[0033] like Figures 5 to 7As shown, in this embodiment, one end of each of the two sets of mounting rods 203 is provided with a U-shaped frame 401. A mounting cylinder 403 is rotatably connected to the U-shaped frame 401 via a mounting sleeve 404. A movable block 501 is provided inside the mounting cylinder 403. The movable block 501 and the U-shaped frame 401 are connected via a first fixing component. The movable block 501 and the mounting cylinder 403 can rotate along the mounting sleeve 404 and are fixed in position by the first fixing component. The movable block 501 can rotate inside the mounting cylinder 403 and is fixed in position by a second fixing component. A rotatably mounted connecting cylinder 601 is provided at the bottom of the mounting cylinder 403. A hemostatic block 602 is detachably provided at the bottom of the connecting cylinder 601. A square rod 508 at the bottom of the movable block 501 slides through the connecting cylinder 601.

[0034] The first fixing component includes a mounting ring 502 sleeved on the movable block 501. The mounting ring 502 is provided with two sets of connecting posts 503. One end of the connecting post 503 is provided with a locking block 504. The connecting post 503 is located inside the mounting sleeve 404. The locking block 504 is slidably locked in the groove 405 opened at one end of the mounting sleeve 404. The inner side of the U-shaped frame 401 is provided with two sets of internal toothed rings 402. Multiple sets of locking grooves are evenly arranged on the inner circular surface of the internal toothed rings 402. The mounting sleeve 404 passes through the internal toothed rings 402. The locking block 504 is locked in the locking groove on the inner side of the internal toothed rings 402. The mounting cylinder 403 is provided with a cover 509. The movable block 501 is provided with a handle 506 connected by a connecting rod 505. A third return spring 510 is sleeved on the connecting rod 505. The two ends of the third return spring 510 are in contact with the movable block 501 and the cover 509, respectively.

[0035] When adjusting the lateral position of the hemostatic block 602 using the adjusting components, the lateral movement of the two sets of mounting rods 203 can be controlled by the handle 506. Additionally, lifting the handle 506 upwards causes the movable block 501 to move upwards, compressing the third return spring 510. During this upward movement, the movable block 501 moves the mounting ring 502 upwards, which in turn moves the locking block 504 upwards via the connecting post 503. Once the locking block 504 moves upwards and retracts into the slide groove 405, it disengages from the inner toothed ring 402, thus releasing the position fixation of the mounting sleeve 404. The handle 506 can then rotate the mounting cylinder 403 to adjust the angle of the hemostatic block 602, allowing it to better conform to the wound at various angles. After adjustment, releasing the handle 506 allows the locking block 504 to reset and re-lock into the inner toothed ring 402 under the reset capability of the third return spring 510, thus fixing the position of the mounting cylinder 403. The angle of the hemostatic block 602 can be quickly adjusted through the above operations, further improving the efficiency of cardiology emergency treatment.

[0036] like Figures 5 to 7As shown, in this embodiment, the second fixing component includes a first toothed disc 507 fixedly disposed at the bottom of the movable block 501 and a second toothed disc 406 fixedly disposed at the bottom of the inner side of the mounting cylinder 403. The teeth at the bottom of the first toothed disc 507 are engaged in the toothed grooves opened on the second toothed disc 406. When the handle 506 is lifted upward, the movable block 501 moves upward, causing the first toothed disc 507 to disengage from the second toothed disc 406. The movable block 501 can then be rotated within the mounting ring 502 by rotating the handle 506. This allows the hemostatic block 602 to rotate along the axis of the connecting cylinder 601 through the cooperation of the square rod 508 and the connecting cylinder 601. This allows for adjustment of the hemostasis position according to the longitudinal position of the wound, further improving the hemostasis efficiency and range, thereby enhancing the efficiency of cardiology emergency treatment.

[0037] like Figure 6 , 7 As shown, in this embodiment, the tooth length at the bottom of the first toothed disc 507 is the same as the sliding distance of the locking block 504 within the slide groove 405. This prevents the first toothed disc 507 from remaining stuck on the second toothed disc 406 after the locking block 504 disengages from the inner toothed ring 402, and also prevents the locking block 504 from remaining stuck on the inner toothed ring 402 after the first toothed disc 507 disengages from the second toothed disc 406, thus improving the reliability of the device.

[0038] like Figure 1 As shown, two sets of threaded knobs 603 are installed on the bed frame 105. The device can be quickly installed by rotating the threaded knobs 603.

[0039] Specific usage and beneficial effects of the present invention:

[0040] When in use, this cardiology resuscitation device is fixed to one side of the operating table via the bed frame 105 and threaded knob 603. When not in use, the support arm 101 can be positioned perpendicular to the bed to avoid interfering with the surgery. When it is necessary to apply pressure to the patient's wound to stop bleeding, the medical staff holds the first handle 303 and the second handle 308 with one hand and the handle 506 with the other hand, and presses the support arm 101 diagonally downward to rotate the support arm 101 along the pivot 102.

[0041] During rotation, the support arm 101 drives the ratchet 103 to rotate, thereby fixing the position of the rotated support arm 101 through the engagement of the ratchet 103 and the pawl 108. Simultaneously, while rotating the support arm 101, one hand closes the first handle 303 and the second handle 308, causing the control lever 301 to move within the inclined frame 206. This, in turn, engages with the inner inclined surface of the inclined frame 206 to control the toothed block 205 to move downwards and disengage from the fixing groove 204, thus releasing the fixation of the two sets of mounting rods 203. At the same time, the other hand moves the mounting rod 203 within the support cylinder 202 by laterally moving the handle 506, adjusting the lateral position of the hemostatic block 602. After adjustment, releasing the first handle 303 and the second handle 308 locks the mounting rod 203 in place.

[0042] When adjusting the lateral position of the hemostatic block 602, the movable block 501 can be moved upward by lifting the handle 506, causing the locking block 504 to disengage from the inner toothed ring 402 and release its fixation on the mounting sleeve 404. Simultaneously, lifting the handle 506 also disengages the first toothed disc 507 from the second toothed disc 406, releasing the fixation on the movable block 501's rotation along its axis. The mounting cylinder 403 can then be rotated along the mounting sleeve 404 by operating the handle 506, simultaneously causing the movable block 501 to rotate inside the mounting cylinder 403. This allows for adjustment of the angle of the hemostatic block 602 according to the angle of the patient's wound, and rotation of the hemostatic block 602 according to the specific location of the wound, ensuring better fit. After adjustment, releasing the handle 506 allows the locking block 504 to re-lock into the inner toothed ring 402 under the action of the third return spring 510, and the first toothed disc 507 to re-lock onto the second toothed disc 406, completing the hemostasis process.

[0043] When performing hemostasis on a patient, this cardiology emergency device can quickly move the hemostatic block 602 to the wound according to the location of the wound, ensuring that the hemostatic block 602 is well attached to the wound. Moreover, the entire hemostasis process does not require complicated operations and can be completed in just a few seconds, effectively reducing the amount of bleeding and saving rescue time.

[0044] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
