Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable pressure-assisted bone marrow aspiration device. Background Technology

[0002] Bone marrow aspiration is a common medical procedure for collecting bone marrow fluid, used for the diagnosis of hematological diseases and the evaluation of treatment effects. During the procedure, the patient's limb must be kept immobilized, and medical staff must apply pressure to the tissues around the puncture site to stabilize the limb and reduce movement during the procedure. After the needle is withdrawn, the puncture site should be immediately covered with sterile gauze or cotton balls, and continuous, vertical pressure should be applied by medical staff or the patient (under guidance). The pressure should be appropriate, avoiding too light pressure which may cause bleeding, or too heavy pressure which may cause local tissue damage. Normally, pressure should be applied for 5-10 minutes; if the patient has abnormal coagulation function (such as thrombocytopenia or is taking anticoagulants), the pressure should be extended to 15-20 minutes, until no bleeding or oozing is confirmed.

[0003] In traditional operations, the pressure applied depends entirely on the experience of medical staff. Prolonged manual pressing can easily cause fatigue in medical staff, further affecting the stability of the operation. Existing auxiliary devices are mostly simple fixed structures, which cannot achieve precise and real-time adjustment of pressure, making it difficult to meet the refined needs of clinical operations.

[0022] Please see Figures 1-3 and Figures 9-11 The adjustment mechanism shown in the figure includes a swing rod 33 installed on the side of the rotating frame 1. A second electric telescopic rod 34 is fixedly connected to the swing rod 33. The telescopic end of the second electric telescopic rod 34 is rotatably connected to the rotating frame 1. A support rod 35 is rotatably connected to the swing rod 33. A rotating platform 36 is rotatably connected to the bottom of the support rod 35. A fixing component 37 for fixing is provided on the rotating platform 36. The fixing component 37 includes a guide rail 38 fixedly installed on the bottom of the bed. A sliding block 39 is slidably connected to the guide rail 38. A plug-in frame 40 that can be plugged into and fixed to the side of the rotating platform 36 is fixedly connected to the sliding block 39. The sliding block 39, the plug-in frame 40, the rotating platform 36, the support rod 35 and the rotating frame 1 are all provided with limiting structures for adjusting and limiting the position and angle.

[0023] Working principle: After adjusting and fixing the sliding block 39 to the desired position, fix the rotating platform 36 and the insertion frame 40. Then rotate the support rod 35, swing rod 33, and rotating frame 1 to control the second electric telescopic rod 34 to push the rotating frame 1, so that the rubber sleeve 41 on the side of the fixing ring 2 contacts and presses against the desired position, and the pressing angle can be adjusted appropriately. At this time, the rotating plate 10 and the rotating frame 1 are at a right angle, and the middle position of the fixing ring 2 is in the open state. Start the first electric telescopic rod 5 to push the fixing ball 6, so that the fixing block 7 pushes the arc plate 3 to move. The side of the arc plate 3 pushes the inner wall of the rubber sleeve 41, and the outer wall of the rubber sleeve 41 presses against the perimeter of the desired puncture position. During the pushing process, the pressure sensor 32 on the arc plate 3 senses the pressing pressure. The corresponding electric telescopic rods are controlled to extend and retract, allowing multiple sets of arc-shaped plates 3 to press the required position relatively evenly. The arc-shaped plates 3 are made of plastic material with a certain degree of elasticity. When the multiple sets of arc-shaped plates 3 are pushed to different distances, the slight bending of the arc-shaped plates 3 and the elastic connection of the connecting block 4 can ensure that the multiple sets of arc-shaped plates 3 form a relatively smooth circular shape for pressing. The fixed ball 6 can rotate inside the rolling groove 8, improving the flexibility of the movement of the arc-shaped plates 3. This structure is more stable and fits better than traditional hard plate support or airbag support, and can stably provide appropriate support force to ensure continuous and stable pressing intensity around the puncture point. The first tension spring 9 can initially limit and adjust the position of the arc-shaped plates 3, making it easy to reset the arc-shaped plates 3 to the required position later.

[0024] After the above pressing, a puncture operation can be performed through the middle area of ​​the fixing ring 2. After the puncture is completed, the second locking block 29 is moved to release the locking state between the second locking block 29 and the oblique tooth groove 31. Under the pull of the second tension spring 14, the rotating plate 10 rotates in the opposite direction to the limiting groove 13, and the pressing plate 11 is locked into the middle position of the fixing ring 2. The oblique side of the first locking block 22 abuts against the side of the mounting block 24 and slides into the locking groove 25, completing the limiting of the pressing plate 11. Then, the pressure controller 17 is used to inflate and pressurize the position of the rubber ring 18 and the mounting plate 19. The rubber ring 18 is stretched, causing the mounting plate 19 to push the sterile gauze 20 to gradually press against the patient's body. The pressure sensor 32 on the mounting plate 19 senses the pressure. The pressure applied is controlled by the pressure controller 17, which flexibly controls the air pressure inside the rubber ring 18 to adjust the pressure of the sterile gauze 20 on the puncture site in real time. At this time, because the rubber ring 18 is supported by the fixing ring 2 and the rubber sleeve 41, the mounting plate 19 can move relatively stably inside the rubber sleeve 41 to the required pressing position without deviation. In actual use, since patients are generally cooperative and local anesthesia is administered, patients generally do not move much, and the position of the pressing point does not change much. When a slight adjustment is detected in the pressing position, causing a change in the reading of the pressure sensor 32, the pressing situation can be adjusted again by controlling the first electric telescopic rod 5 and the pressure controller 17 to ensure the orderly progress of the bone marrow puncture process.

[0025] After pressing, remove the entire device and move the first locking block 22 to release the locking state of the first locking block 22 to the locking groove 25. Then continue to pull the first locking block 22 so that the pressing plate 11 and the rotating plate 10 rotate around the rotating shaft 12 to a position perpendicular to the rotating frame 1. The rotating shaft 12 drives the rotating disk 27 to rotate. The inclined surface of the oblique tooth groove 31 continuously slides against the inclined surface of the second locking block 29. After releasing the pressing plate 11, the second locking block 29 completes the one-way locking limit operation with the oblique tooth groove 31 under the push of the second spring 30. The second tension spring 14 is stretched, and then the multiple sets of first electric telescopic rods 5 are controlled to pull back so that the arc plate 3 is reset, thus completing the overall reset of the device. After that, the sterile gauze 20 can be removed from the mounting plate 19 for replacement. At the same time, the rubber sleeve 41 and the rubber ring 18 can be cleaned and disinfected. The device is flexible and convenient to use, which can greatly improve the efficiency of puncture and pressing and relieve the operational pressure of medical staff.

[0026] It is worth noting that installing guide rails 38 and sliding blocks 39 on the bottom of the medical bed or operating table can make the device easier to use. If not, a clamping structure can be set on the rotating table 36 to clamp and fix the rotating table 36 in the required position.
