Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for pressing and stopping bleeding on wounds after surgery for hematological diseases. Background Art

[0002] In the clinical treatment of blood system diseases, patients with leukemia, hemophilia, aplastic anemia, etc. have significant defects in the coagulation mechanism due to abnormal platelet count, coagulation factor deficiency or dysfunction. When such patients undergo surgical treatment, accompanied by thrombocytopenia, coagulation factor deficiency or vascular wall abnormalities, the risk of postoperative wound bleeding is significantly higher than that of ordinary patients. At present, conventional compression hemostasis devices are assembled from a wristband and a compression pad. A knob is provided at the connection between the wristband and the compression pad. By rotating the knob, the compression pad can be tightened. The compression pad and wristband are worn on the postoperative position of the arm to compress and stop bleeding. If the operator's arm position is moved, the arm bending movement will tilt the compression position of the compression pad, causing the position of the compression pad and the wound surface to tilt and loosen. The tilted and loose compression pad will affect the hemostasis efficiency of the wound surface of the blood disease patient. For this reason, a compression hemostasis device for the wound surface after blood disease surgery is designed. Summary of the Invention

[0003] The purpose of the present invention is to provide a device for pressing and stopping bleeding on wounds after blood disease surgery, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a device for pressing and stopping bleeding after operation of a blood disease wound, comprising a main board, wherein the left and right ends of the main board are symmetrically fixedly connected with two connecting rods, characterized in that: The sliding mechanism further comprises two sections of guide rails fixedly connected to the front and rear ends of the connecting rod, the bottom of the guide rails being slidably connected to a roller, and the top of the main board being fixedly and rotatably connected to a drive knob; The driving mechanism further includes a turntable fixedly connected to the outer wall of the driving knob, a driven rod being threadedly connected to the inner wall of the driving knob, a plurality of driven blocks being fixedly connected around the bottom of the turntable, a driving rod being rotatably connected to the top of the main board and at one end near the driving knob, and the inner wall of the driving rod being engaged with the outer wall of the driven block; The clamping mechanism also includes a compression rod slidably connected to the inner wall of the driven rod, the bottom of the driven rod is horizontally symmetrically hinged with two sections of hinged rods, and the bottom of the compression rod is fixedly connected to a main compression pad.

[0005] Preferably, the sliding mechanism includes a guide rail block slidably connected to the inner wall of the guide rail rod, the outer wall of the guide rail block is fixedly connected to a tooth plate, the inner wall of the connecting rod is provided with an inner groove, and the outer wall of the tooth plate is slidably connected to the inner wall of the inner groove.

[0006] Preferably, a gear is rotatably connected to the connection between the guide rail rod and the connecting rod, the bottom of the gear is engaged with the top of the tooth plate, and the top of the roller is fixedly connected to the bottom of the guide rail block.

[0007] Preferably, a guide rail frame is fixedly connected to the top of the mainboard and one end close to the driving rod, a sliding groove is provided on the inner wall of the guide rail frame, and a sliding frame is slidably connected to the inner wall of the sliding groove.

[0008] Preferably, the inner wall of the sliding frame is rotatably connected to the outer wall of the driving rod, one end of the driving rod extends out of the outer wall of the sliding frame, and the extended end of the driving rod is fixedly connected to the adjusting rod.

[0009] Preferably, a second spring is sleeved on the inner wall of the sliding groove, a buckle is rotatably connected to the left side of the sliding frame, and a slot is formed at one end of the guide rail frame close to the buckle.

[0010] Preferably, the clamping mechanism comprises a connecting plate fixedly connected to the outer wall of the compression rod, and two sections of hinged rods are symmetrically hinged on the left and right sides of the connecting plate. Preferably, one end of the hinged rod 2 away from the connecting plate is hinged to the inner wall of the hinged rod 1, and the bottom end of the hinged rod 2 is hinged to an auxiliary compression pad.

[0011] Preferably, the inner wall of the driven rod is provided with a movable groove, the inner wall of the movable groove is slidably connected to the outer wall of the compression rod, a spring is sleeved at the connection between the inner wall of the movable groove and the compression rod, and the bottom of the main board is fixedly connected with a magic belt.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention features sliding mechanisms on both sides. When an operator uses the device for hemostasis, they rotate the gears to slide the toothed plate along the inner wall of the guide rail. This sliding movement of the toothed plate, coupled to the guide rail block, drives the sliding of the rollers. Multiple rollers restrict the position of the arm during this sliding process, maintaining the stability of the main compression pad's compression position by limiting the arm's position. To prevent tilting, the operator can adjust the roller position by rotating the gears, adjusting the position based on the length of the operator's arm.

[0013] 2. The top of the present invention is provided with a driving mechanism. When decompressing the wound surface after hematological surgery, the operator can decompress the main compression pad by rotating the driving rod. The driving rod will drive the driven block to rotate through engagement, and the driven block will drive the turntable and the driving knob to rotate. During the rotation process, the driving knob will drive the main compression pad to perform a decompression operation. The driving rod can achieve self-locking of the driving knob by engaging with the driven block to prevent the main compression pad from loosening due to accidental touch. At the same time, the main compression pad can also be adjusted to reduce pressure by rotating the driving rod.

[0014] 3. The bottom of the present invention is provided with a clamping mechanism. When the postoperative wound is compressed and hemostatically controlled, after the main compression pad is pressed on the position of the wound, the wound pushes back against the main compression pad through the reaction force. The main compression pad will drive the compression rod and the connecting plate to slide upward. At the same time, the connecting plate will pull back the hinged rod 2 through the hinge. One end of the hinged rod 2 will pull the outer wall of the hinged rod 1. The hinged rods 1 on both sides will move closer to the position of the main compression pad under the action of hinge and pulling, so that the auxiliary compression pads at the bottom of the hinged rod 1 will close to the position of the main compression pad. The closed auxiliary compression pads will clamp the position of the wound, and at the same time, will further assist the compression and hemostasis effect of the main compression pad.

The driving mechanism 5 includes a turntable 501, a driven block 502, a driving rod 503 and an adjusting rod 504. The operator can drive the driven block 502 to rotate by rotating the driving rod 503. When the driven block 502 rotates, the turntable 501 will rotate. The turntable 501 drives the driving knob 4 to rotate. The engagement of the driving rod 503 and the driven block 502 can achieve self-locking of the turntable 501 and the driving knob 4 to prevent the main compression pad 8 from loosening due to accidental touch.

[0020] The sliding mechanism 3 includes a guide rail block 304 slidably connected to the inner wall of the guide rail rod 301. The outer wall of the guide rail block 304 is fixedly connected to the tooth plate 302. The inner wall of the connecting rod 2 is provided with an inner groove 201.

Under the limitation of multiple rollers 305, the position of the arm can be fixed to prevent the movement of the arm from affecting the compression position.

[0022] like Figure 2 As shown, a guide rail frame 601 is fixedly connected to the top of the mainboard 1 and at one end close to the driving rod 503 . A sliding groove 602 is formed on the inner wall of the guide rail frame 601 . A sliding frame 6 is slidably connected to the inner wall of the sliding groove 602 .

[0023] The inner wall of the sliding frame 6 is rotatably connected to the outer wall of the driving rod 503 . One end of the driving rod 503 extends out of the outer wall of the sliding frame 6 . The extended end of the driving rod 503 is fixedly connected to the adjusting rod 504 .

[0024] The inner wall of the sliding groove 602 is sleeved with a second spring 603 , the left side of the sliding frame 6 is rotatably connected with a buckle 604 , and a clamping slot 605 is formed at one end of the guide rail frame 601 close to the buckle 604 .

[0025] Before use, the bottom position of the main compression pad 8 needs to correspond to the position of the wound on the arm, the main board 1 and the main compression pad 8 need to be attached to the position of the wound, and the magic belt 101 needs to be worn and wrapped around the arm, and then manually pulled to the sliding frame 6. The sliding frame 6 drives the driving rod 503 to slide on the inner wall of the guide rail frame 601, so that the driving rod 503 is disengaged from the engagement of the driven block 502, and then the buckle 604 at one end of the sliding frame 6 is inserted through the slot 605, and then the buckle 604 is rotated. The locking mechanism 606 is locked with the card slot 605 in a reverse manner. Before decompression, the operator needs to rotate the card buckle 604 in the reverse direction to unlock it. After unlocking, the sliding frame 6 will slide in the reverse direction under the push of the spring 2 603. The sliding frame 6 will drive the driving rod 503 to slide in the reverse direction to the bottom of the turntable 501. Then, by fine-tuning the rotation of the driving knob 4, the driving rod 503 and the driven block 502 are engaged. At the same time, the driving rod 503 and the sliding frame 6 will remain fixed under the elastic resistance of the spring 2 603.

[0026] like Figure 7As shown, the clamping mechanism 7 includes a connecting plate 702 fixedly connected to the outer wall of the compression rod 701, and two sections of hinged rods 704 are symmetrically hinged on the left and right sides of the connecting plate 702. The end of the hinged rod 704 away from the connecting plate 702 is hinged to the inner wall of the hinged rod 1 703, and the bottom end of the hinged rod 2 704 is hinged to an auxiliary compression pad 801. The inner wall of the driven rod 401 is provided with a movable groove 402, and the inner wall of the movable groove 402 is slidably connected to the outer wall of the compression rod 701. The connection between the inner wall of the movable groove 402 and the compression rod 701 is provided with a spring 1 403, and the bottom of the main board 1 is fixedly connected with a magic belt 101 When in use, the operator needs to rotate the driving knob 4, which will be threadedly engaged with the driven rod 401 during rotation, and the driven rod 401 will be driven by the threaded engagement, and the driven rod 401 will drive the compression rod 701 to move downward, and the compression rod 701 will then drive the main compression pad 8 to press onto the upper surface of the wound to stop bleeding. At the same time, the main compression pad 8 and the compression rod 701 will be resisted by the arm wound, and the compression rod 701 will slide in the opposite direction against the inner wall of the movable groove 402 to squeeze the spring 1 403, and the compression rod 701 drives the connecting plate 70 2 moves synchronously. During the movement, the connecting plate 702 will pull the hinge rod 2 704, and the hinge rod 2 704 will be pulled to the hinge rod 1 703 through the hinge. The hinge rod 1 703 will hinge the auxiliary compression pads 801 on the left and right sides to the main compression pad 8. With the auxiliary compression pads 801 on both sides close together, the arm wound is clamped. With the interaction between the main compression pad 8 and the auxiliary compression pad 801, the arm wound is compressed and hemostatic. The operator can adjust the pressure of the main compression pad 8 and the auxiliary compression pad 801 by continuing to rotate the drive knob 4.

[0027] Working principle and usage process: Before use, it is necessary to align the bottom position of the main compression pad 8 with the position of the wound on the arm, fit the main board 1 and the main compression pad 8 to the position of the wound, and wear the magic belt 101 around the arm, then manually pull it to the sliding frame 6, the sliding frame 6 drives the driving rod 503 to slide on the inner wall of the guide rail frame 601, so that the driving rod 503 is disengaged from the driven block 502, and then insert the buckle 604 at one end of the sliding frame 6 through the slot 605, and then lock it with the slot 605 by rotating the buckle 604. When in use, the operator needs to rotate the driving knob 4, which will be threadedly engaged with the driven rod 401 during rotation, and the driven rod 401 will be driven by the threaded engagement, and the driven rod 401 will drive the compression rod 701 to move downward, and the compression rod 701 will then drive the main compression pad 8 to press onto the upper surface of the wound to stop bleeding. At the same time, the main compression pad 8 and the compression rod 701 will be resisted by the arm wound, and the compression rod 701 will slide in the opposite direction against the inner wall of the movable groove 402, squeezing the spring 1 403, and the compression rod 701 drives the connecting plate 702 The connecting plate 702 moves synchronously, and the connecting plate 702 pulls the hinge rod 2 704 during the movement. The hinge rod 2 704 is then pulled to the hinge rod 1 703 through the hinge. The hinge rod 1 703 will bring the auxiliary compression pads 801 on the left and right sides together toward the main compression pad 8 through the hinge. With the auxiliary compression pads 801 on both sides close together, the arm wound is clamped. With the interaction between the main compression pad 8 and the auxiliary compression pad 801, the compression and hemostasis effect on the arm wound is achieved. The operator can adjust the pressure of the main compression pad 8 and the auxiliary compression pad 801 by continuing to rotate the drive knob 4. After wearing, the operator needs to rotate the gear 303. The gear 303 will drive the tooth plate 302 to move through engagement. The tooth plate 302 will slide on the inner wall of the inner groove 201. The tooth plate 302 will drive the guide block 304 to slide on the inner wall of the guide rod 301. At the same time, the guide block 304 will drive the roller 305 to slide synchronously along the path of the guide rod 301. Multiple rollers 305 will limit the arm during the sliding process. Under the limitation of multiple rollers 305, the position of the arm can be fixed to prevent the movement of the arm from affecting the compression position.

[0028] During the process of compressing and stopping bleeding, the operator needs to decompress the main compression pad 8 and the auxiliary compression pad 801 at intervals. Before decompression, the operator needs to reversely rotate the buckle 604 to unlock it. After unlocking, the sliding frame 6 will slide in the opposite direction under the push of the spring 2 603. The sliding frame 6 will drive the driving rod 503 to slide in the opposite direction to the bottom of the turntable 501, and then fine-tune the rotation of the driving knob 4 so that the driving rod 503 and the driven block 502 are engaged. At the same time, the driving rod 503 is resisted by the elastic force of the spring 2 603. 03 and the sliding frame 6 will remain fixed, and the operator can rotate the driving rod 503 by rotating the adjusting rod 504. The driving rod 503 drives the driven block 502 and the turntable 501 to rotate through engagement, and the turntable 501 drives the driving knob 4 to rotate in the opposite direction. The reverse rotating driving knob 4 will realize the reverse displacement of the driven rod 401 and the compression rod 701 through threaded cooperation, and decompress the main compression pad 8 and the auxiliary compression pad 801. When the main compression pad 8 and the auxiliary compression pad 801 are decompressed and leave the arm wound, hemostasis can be completed.
