Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an automatic anti-blockage device, equipment, and storage medium for postoperative drainage tubes in spinal surgery. Background Technology
[0002] Spinal surgery is an important means of treating degenerative spinal diseases, trauma, infection, and tumors. Postoperatively, drainage tubes are routinely placed to prevent postoperative complications, especially hematoma and infection in the surgical area. Maintaining a patent drainage system is crucial for maintaining postoperative tissue pressure balance, reducing blood and exudate retention, and alleviating nerve compression.
[0003] Postoperative hematoma is one of the most serious complications of spinal surgery, especially epidural hematomas that easily form within the spinal canal. These hematomas can compress the spinal cord or nerve roots, potentially causing rapid sensory disturbances, motor dysfunction, or even paralysis. Related literature reports that the incidence of symptomatic hematoma after anterior cervical decompression surgery can reach 3.1%, with most cases occurring within 24 hours postoperatively. A study by Yi et al. indicated that postoperative epidural hematoma formation is closely related to inadequate drainage and is one of the main causes of acute neurological dysfunction. A retrospective study found that despite intraoperative drainage tube placement, nearly half of the patients still had the drainage tube in place when epidural hematoma was diagnosed, indicating that drainage tube blockage can lead to hematoma formation.
[0004] Currently, the most commonly used drainage methods in clinical practice are passive drainage or continuous negative pressure drainage. However, due to their simple structural design, they cannot sense or adjust the pressure within the lumen in real time, which easily leads to the following problems: 1. Lumen blockage: In the early postoperative period, fibrin, blood clots, tissue debris, etc. in the blood can easily deposit in the drainage lumen, forming a mechanical blockage; 2. Insufficient pressure or backflow: Traditional negative pressure systems have a fixed pressure. If the drainage bottle is not positioned properly or the negative pressure drops, the fluid in the surgical cavity cannot be effectively drained. 3. There is no alarm mechanism after blockage, making it difficult for clinicians to detect in time. The drainage port may appear normal, but fluid may have already accumulated in the surgical cavity, delaying the intervention time.
[0005] Drainage tube blockage is an independent risk factor for postoperative hematoma formation and increased reoperation rates. Therefore, there is an urgent need to develop an automatic anti-blockage device for drainage tubes. Summary of the Invention
[0006] The purpose of this invention is to solve the technical problems existing in the prior art and to provide a drainage device with adjustable function that intermittently generates negative pressure.
[0007] To achieve the above objectives, the present invention provides an anti-blockage device for postoperative drainage tubes in spinal surgery, comprising: ontology; A pressurization module includes a first pressurization bar, a second pressurization bar, and a third pressurization bar arranged sequentially. The first pressurization bar, the second pressurization bar, and the third pressurization bar move independently. The pressurization module is electrically connected to a control module and moves periodically under the control of the control module. The pressurizing module is fitted around the outer periphery of the drainage tube during use. The pressurizing module moves up and down in the radial direction of the drainage tube. Through the periodic adjustment of the control module, the automatic pressurization and drainage of the drainage tube are realized.
[0008] Preferably, the body is a cavity with a central through opening, the pressurization module is disposed in the cavity of the body, the first pressurization strip, the second pressurization strip and the third pressurization strip are arranged in a straight line, and the first pressurization strip, the second pressurization strip and the third pressurization strip are disposed on the inner wall of the cavity of the body.

[0010] Preferably, the control module includes a microcontroller with built-in timing logic. When the microcontroller executes the timing logic, it drives the pressurization module to perform a preset action cycle.
[0011] Preferably, the pressurization module further includes a support frame, which is fixedly connected to the inner wall of the cavity of the main body through a fixing column, and the support frame is an inwardly concave arc shape, so that the support frame fits against the outer wall of the drainage tube.

[0013] Preferably, the first pressure strip, the second pressure strip, and the third pressure strip are downwardly convex arcs, and the curvature of the first pressure strip, the second pressure strip, and the third pressure strip is the same as the curvature of the support frame. When the first pressure strip, the second pressure strip, and the third pressure strip move downward to press the drainage tube, the first pressure strip, the second pressure strip, and the third pressure strip are in close contact with the upper surface of the support frame.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] Example 1 An anti-blockage device for post-spinal surgery drainage tubes includes: a body, the body being a cavity with a central through-hole; and a pressurizing module disposed within the body. The pressurizing module includes a first pressurizing strip, a second pressurizing strip, and a third pressurizing strip arranged sequentially. The first, second, and third pressurizing strips move independently. The pressurizing module is electrically connected to a control module and moves periodically under the control of the control module. During use, the pressurizing module is fitted around the outer periphery of the drainage tube, and moves up and down radially along the drainage tube. Automatic pressurization and drainage of the drainage tube are achieved through periodic adjustment by the control module. The first, second, and third pressurizing strips are arranged in a straight line and are disposed on the inner wall of the cavity of the body. A first slot is provided on one side of the body to provide accommodating space for the control module.
[0022] The control module includes a microcontroller with built-in timing logic. When the microcontroller executes the timing logic, it drives the pressurization module to perform a specific action cycle.
[0023] The cavity of the main body is also provided with a support frame, which is fixedly connected to the inner wall of the cavity of the main body through a fixing post. The support frame is an inwardly concave arc shape, so that the support frame fits against the outer wall of the drainage tube. Both ends of the support frame are provided with buckles for locking the drainage tube. The first, second, and third pressure strips are downwardly convex arc shapes, and the arc of the first, second, and third pressure strips is the same as the arc of the support frame. When the first, second, and third pressure strips move downward to press against the drainage tube, the first, second, and third pressure strips are in close contact with the upper surface of the support frame.
[0024] One end of the drainage tube is placed at the patient's wound, and the other end passes through the buckle and then connects to the collection device at the bottom.
[0025] It should be noted that the first, second, and third pressure bars have the same structure, and will be described as pressure bars below. The pressure bar includes a base and an extension. The base is square and the extension is arc-shaped. The base and the extension are connected by a lifting screw. A micro motor is installed inside the base. The motor drives the lifting screw to move, and within a limited range, moves the extension vertically. This movement is along the radial direction of the drainage tube.
[0026] Using a microcontroller as its core, the system periodically controls the opening and closing of the pressure strips, thus alternating between negative and normal pressure states: when the head pressure strip closes, the central pressure strip closes, and the air in this section of the drainage tube is vented; when the tail pressure strip closes and the head and central pressure strips open, the drainage system maintains negative pressure, and the fluid is extracted; when the tail pressure strip relaxes, the drainage tube returns to normal pressure, the tissue rebounds, and the deposits are released; this periodic control achieves self-cleaning circulation and prevents blockage.
[0027] Specifically, the control module's workflow is as follows: First, the microcontroller starts a timer, the first pressure bar closes, the second pressure bar closes to purge air, and the third pressure bar closes. Then, the first and second pressure bars open to achieve negative pressure drainage. Finally, the third pressure bar relaxes to release the negative pressure and remove any deposits. The system then checks if a cycle has been completed. If not, the cycle restarts immediately; otherwise, it ends. The unit cycle time is preset and can be adjusted at any time.
[0028] The intermittent negative pressure control mechanism of this invention employs automated cyclic control to achieve periodic alternation between negative and normal pressure states, resolving the problems of tissue impaction and blood clot deposition caused by traditional continuous negative pressure drainage. Multiple pressure strips work in tandem, with the head, center, and tail strips controlled sequentially to form three stages: local emptying, negative pressure aspiration, and paused self-cleaning. Adjustable parameters (such as negative pressure duration T1, interval time T2, number of cycles, and total running time) can be set, adapting to different surgical types and drainage needs, and possessing universal clinical applicability.
