Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a tracheostomy patient positioning device. Background Technology

[0002] In hospital treatment, tracheotomy is a common surgical procedure in neurosurgery and neurology. By cutting open the anterior wall of the trachea in the cervical segment and inserting a tracheostomy tube, a new channel for breathing is established. It is mainly used for critically ill patients with lung infections who are in a coma and unable to cough up sputum on their own, which helps prevent further deterioration of the lung infection.

[0003] During tracheotomy, there are certain requirements for the patient's position, which needs to fully expose the larynx to facilitate the operation. Since this surgery is usually performed under anesthesia, the patient's consciousness is impaired after anesthesia, and the head and neck are prone to deflection due to gravity, thus affecting the surgical procedure. In addition, during the actual operation, the patient's head is also prone to drooping, causing the chin to rub against the neck, which can obstruct the neck during the operation and affect the surgical procedure. Therefore, a tracheotomy patient positioning device is proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a tracheostomy patient positioning adjustment device, which solves the problems mentioned in the background section regarding the poor consciousness of patients after anesthesia, the tendency for the head and neck to shift due to gravity, thus affecting surgical procedures, and the tendency for the patient's head to droop.

[0020] This invention discloses a tracheostomy patient positioning device, which has the following beneficial effects:

[0021] 1. This tracheotomy patient positioning device, through the connection relationship between the medical bed, connecting block, drive motor, first positioning plate, and second positioning plate, allows the drive motor to move both the first and second positioning plates simultaneously towards the center when activated. This facilitates the restriction and positioning of both sides of the patient's head and neck. Simultaneous inward movement also allows for adjustment of the patient's head and neck position, maintaining balance and facilitating tracheotomy surgery. Furthermore, the connection relationship between the baffle, connecting column, connecting plate, fixing box, and second positioning plate allows the moving second positioning plate to move the fixing box forward, which in turn moves the connecting column to the right side of the patient's head. The baffle then flips forward and downward, positioning itself horizontally under the patient's chin, effectively separating the patient's head from the neck. This facilitates tracheotomy surgery and prevents the patient's head from colliding with the trachea, enhancing its ease of use and practicality.

[0022] 2. This tracheostomy patient positioning device, through the connection relationship of connecting column, adjusting shaft, rotating plate, insertion rod and insertion hole, allows the front end of the insertion rod to engage with the corresponding insertion hole. There are multiple sets of insertion holes, corresponding to different positioning angles of the baffle. Medical staff hold the adjusting shaft and pull the adjusting ring backward with their fingertips. The backward movement of the adjusting ring causes the insertion rod to move backward, so that the rear end of the insertion rod disengages from the insertion hole. At this time, by rotating the adjusting shaft, the adjusting shaft drives the baffle to rotate, which facilitates the adjustment of the baffle according to the angle of the patient's chin, making it easier to lift the patient's chin and position the patient's chin, making it easier for the doctor to access the patient's neck for treatment.

[0023] 3. This tracheotomy patient positioning device, through the connection relationship of connecting blocks, support columns, rotating screws, moving plates, clamping plates, and adjusting columns, allows the medical bed board to be inserted between the clamping plate and the connecting blocks. By rotating the adjusting column, the clamping plate is moved upward, pressing against the bottom of the medical bed board, facilitating the clamping of the device onto the medical bed and preventing the device from moving arbitrarily during use. Multiple sets of connecting holes are provided to accommodate different thicknesses of the medical bed board. After the clamping plate and connecting blocks clamp the medical bed, the rotation of the adjusting column is stopped. At this point, the right end of the fixing screw is passed through the corresponding connecting hole and tightened into the threaded hole on the outer wall of the connecting block, fixing the position of the rotating disc and thus clamping and fixing the device onto the medical bed board, improving the stability of the device during use.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This application provides a tracheostomy patient positioning adjustment device, which solves the problems in the prior art where patients are in a poor state of consciousness after anesthesia, and their head and neck are easily deflected and moved due to gravity, thus affecting surgical operations and causing the patient's head to droop. The device adjusts the patient's head and neck position to keep them balanced, facilitating tracheostomy surgery for medical staff. It also allows a baffle 3 to be placed across the patient's chin to separate the head and neck, making tracheostomy easier for doctors and preventing the patient's head from moving and colliding with the trachea. This device is easy to use and improves its practicality.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] This invention discloses a tracheostomy patient positioning device, according to the attached... Figure 1-10 As shown, it includes a medical bed 1, on which the patient lies to be supported, making it easier for the doctor to perform a tracheotomy.

[0040] The medical bed 1 is equipped with a positioning component that acts on both sides of the patient's head to adjust and position the patient's head and neck.

[0041] The positioning assembly includes a connecting block 2, a drive motor 201, a first positioning plate 205, and a second positioning plate 207. The drive motor 201 is fixedly mounted at the front end of the connecting block 2, and a bidirectional screw 202 is provided at the rear end of the drive motor 201. The threads on both sides of the outer wall of the bidirectional screw 202 are symmetrical. A first moving block 204 is threadedly connected to the outer wall of the bidirectional screw 202, and the first moving block 204 is fixedly connected to the first positioning plate 205. A second moving block 206 is threadedly connected to the outer wall of the bidirectional screw 202, and the second moving block 206 is fixedly connected to the second positioning plate 207. By starting the drive motor 201, the drive motor 201 drives the bidirectional screw 202 to rotate counterclockwise to the left. The leftward rotation of the bidirectional screw 202 drives the first moving block 204 to move along the bidirectional screw 205. 2. The threaded direction on the front side of the outer wall moves backward, causing the first moving block 204 to move backward, driving the first positioning plate 205 to move backward. The double-acting screw 202, which rotates counterclockwise to the left, drives the second moving block 206 to move forward along the threaded direction on the rear side of the outer wall of the double-acting screw 202. This causes the second moving block 206 to move forward, driving the second positioning plate 207 to move forward. The simultaneous movement of the first positioning plate 205 and the second positioning plate 207 towards the center facilitates the restriction and positioning of both sides of the patient's head and neck. The simultaneous inward movement also facilitates the adjustment of the patient's head and neck position, ensuring balance. Furthermore, the positions of the first positioning plate 205 and the second positioning plate 207 can be automatically adjusted according to the width of the patient's head, making it convenient to use and improving its practicality.

[0042] By setting up the connection relationship between the medical bed, connecting block, drive motor, first positioning plate, and second positioning plate, the drive motor can be activated to move both the first and second positioning plates simultaneously towards the center. This facilitates the restriction and positioning of both sides of the patient's head and neck. Simultaneous inward movement also allows for adjustment of the patient's head and neck position, maintaining balance and facilitating tracheotomy. Furthermore, by setting up the connection relationship between the baffle, connecting column, connecting plate, fixing box, and second positioning plate, the moving second positioning plate can drive the fixing box forward, causing the connecting column to move to the right side of the patient's head. The baffle then flips forward and downward, positioning itself horizontally under the patient's chin, effectively separating the patient's head from the neck. This facilitates tracheotomy and prevents the patient's head from colliding with the trachea.

[0043] The second positioning plate 207 is provided with a limiting component at its top. This limiting component acts on the patient's chin to limit the patient's head. The limiting component includes a baffle 3, a connecting post 301, and a fixing box 4. The fixing box 4 is fixedly installed on the rear wall of the second positioning plate 207, and a groove is opened at the top of the fixing box 4. The bottom of the connecting post 301 is movably inserted into the groove opened at the top of the fixing box 4. A connecting plate 302 is provided at the front end of the connecting post 301, and the baffle 3 is rotatably connected to the connecting plate 302 by a hinge. The forward movement of the second positioning plate 207 drives the fixing box 4 to move forward, which in turn drives the connecting post 301 to move forward. The forward movement of the connecting post 301 drives the connecting plate 302 to move forward, which in turn drives the baffle 3 to move forward. By flipping the baffle 3 downward, the baffle 3 is placed horizontally at the patient's chin, which facilitates the separation of the patient's head and neck, making it easier for doctors to perform tracheotomy on the patient's neck, and also helps to prevent the patient's head from moving and hitting the trachea.

[0044] A circular hole is provided through the rear wall of the connecting column 301, and an adjusting shaft 303 is rotatably inserted into the inner cavity of the circular hole through the rear wall of the connecting column 301. The adjusting shaft 303 is fixedly connected to the connecting plate 302, which facilitates the adjustment of the use angle of the baffle 3. By rotating the adjusting shaft 303, the connecting plate 302 is driven to rotate, which in turn drives the baffle 3 to rotate, so that the baffle 3 lifts the patient's chin, making it easier for the doctor to touch the patient's neck for treatment.

[0045] Medical staff hold the adjustment shaft and pull the adjustment ring backward with their fingertips. The backward movement of the adjustment ring causes the insertion rod to move backward, so that the rear end of the insertion rod is disengaged from the insertion hole. At this time, by rotating the adjustment shaft, the adjustment shaft causes the baffle to rotate, which makes it easy to adjust the baffle according to the angle of the patient's chin, making it easier to lift the patient's chin and locate the position of the patient's chin, making it easier for the doctor to touch the patient's neck for treatment.

[0046] A rotating plate 304 is fixedly installed on the outer wall of the adjusting shaft 303. A rod 306 is inserted through the outer wall of the rotating plate 304. A hole 310 is opened on the rear wall of the connecting column 301. The front end of the rod 306 is engaged in the corresponding hole 310. There are multiple sets of holes 310, corresponding to different positioning angles of the baffle 3. Users can choose according to their needs for convenient use. By inserting the rod 306 into the corresponding hole 310, the position of the rotating plate 304 is fixed, thereby fixing the position of the baffle 3.

[0047] The inner wall of the rotating plate 304 has a connecting groove 305, and a first spring strip 307 is fixedly installed on the inner wall of the connecting groove 305. A push plate 308 is fixedly installed on the other end of the first spring strip 307. The push plate 308 is fixedly installed on the outer wall of the insertion rod 306. The push plate 308 is automatically pushed forward by the pushing force of the first spring strip 307, so that the forward-moving push plate 308 drives the insertion rod 306 to move forward, so that the rear end of the insertion rod 306 is automatically inserted into the corresponding insertion hole 310, thereby fixing the position of the rotating plate 304.

[0048] Medical staff hold the adjustment shaft 303 and pull the adjustment ring 309 backward with their fingertips. The backward movement of the adjustment ring 309 causes the insertion rod 306 to move backward, so that the rear end of the insertion rod 306 disengages from the insertion hole 310. At this time, by rotating the adjustment shaft 303, the adjustment shaft 303 drives the connecting plate 302 to rotate. The rotating connecting plate 302 drives the baffle 3 to rotate, which makes it easy to adjust the baffle 3 according to the angle of the patient's chin and to facilitate the positioning of the patient's chin.

[0049] A slider 501 is fixedly installed at the rear end of the connecting column 301, and a groove 401 is provided on the outer wall of the fixing box 4. The rear end of the slider 501 extends backward through the groove 401 and is fixedly installed with a sliding block 5. The slider 501 moves within the groove 401 to limit the movement path and range of the connecting column 301.

[0050] The sliding block 5 has a groove at its front end, and an insert plate 503 is inserted through the inner wall of the groove. The outer wall of the fixed box 4 has a slot 402. Multiple slots 402 are provided, and medical staff can select the position according to the patient's head and neck position for convenient use. The front end of the insert plate 503 is engaged in the corresponding slot 402. An adjustment plate 506 is fixedly provided at the rear end of the insert plate 503, and an adjustment handle 507 is fixedly provided at the rear end of the adjustment plate 506. By engaging the front end of the insert plate 503 in the corresponding slot 402, the position of the sliding block 5 is restricted, thereby fixing the position of the connecting column 301. This facilitates the fixing of the position of the baffle 3, which separates the patient's chin from the surgical site, making subsequent surgical operations easier for medical staff.

[0051] The inner wall of the sliding block 5 has an installation groove 502, and a second spring strip 504 is fixedly installed on the inner wall of the installation groove 502. A pressing plate 505 is fixedly installed on the other end of the second spring strip 504, and the pressing plate 505 is fixedly installed on the outer wall of the insert plate 503. The sliding block 5 is located on the left side of the connecting block 2. The pressing plate 505 is automatically pushed forward by the pushing force of the second spring strip 504, so that the pressing plate 505 moves forward and drives the insert plate 503 to move forward, so that the insert plate 503 is inserted into the corresponding slot 402, thereby restricting the sliding block 5 at this position and fixing the use position of the baffle 3.

[0052] The left wall of the connecting block 2 has a movable groove 203, and the left ends of the first positioning plate 205 and the second positioning plate 207 are movably inserted into the movable groove 203 to limit the moving path and moving range of the first positioning plate 205 and the second positioning plate 207. A soft pad 208 is fixedly provided at the front end of the second positioning plate 207, and an ear groove 209 is provided on the outer wall of the soft pad 208 to improve comfort and facilitate patient use.

[0053] A support column 6 is fixedly installed at the bottom of the connecting block 2, and a rotating screw 601 is rotatably connected to the inner wall of the inner cavity of the support column 6 via a bearing. A moving plate 602 is threadedly connected to the outer wall of the rotating screw 601. A transmission groove 604 is opened on the outer wall of the support column 6, and a clamping plate 603 is fixedly installed at the right end of the moving plate 602 through the transmission groove 604. The bed board of the medical bed 1 is inserted between the clamping plate 603 and the connecting block 2. An adjusting column 606 is rotatably inserted at the left end of the connecting block 2, and a second bevel gear 607 is fixedly installed at the right end of the adjusting column 606. A first bevel gear 605 is fixedly installed on the outer wall of the rotating screw 601, and the outer wall of the first bevel gear 605 meshes with the outer wall of the second bevel gear 607.

[0054] By fitting the clamping plate 603 and connecting block 2 onto the bed board of the medical bed 1, and by rotating the adjusting column 606 counterclockwise, the rotating adjusting column 606 drives the second bevel gear 607 to rotate backward. This causes the outer wall of the rotating second bevel gear 607 to press and push the first bevel gear 605, causing the first bevel gear 605 to rotate counterclockwise to the left. The leftward rotation of the first bevel gear 605 drives the moving plate 602 to move upward, and the upward movement of the moving plate 602 drives the clamping plate 603 to move upward, so that the clamping plate 603 presses against the bottom of the bed board of the medical bed 1. This facilitates the clamping and installation of the device on the medical bed 1, prevents the device from moving randomly during use, and improves the stability of the device during use.

[0055] A rotating disk 608 is fixedly mounted on the outer wall of the adjusting column 606, and a connecting hole 609 is provided through the outer wall of the rotating disk 608. Multiple sets of connecting holes 609 are provided to correspond to the positioning of different thicknesses of the medical bed 1's bed board. A fixing screw 610 is movably inserted into the inner wall of the connecting hole 609. A threaded hole is provided on the outer wall of the connecting block 2, and the right end of the fixing screw 610 is threaded into the threaded hole on the outer wall of the connecting block 2. After the clamping plate 603 and the connecting block 2 clamp the medical bed 1, the rotation of the adjusting column 606 stops. When the corresponding connecting hole 609 is aligned with the threaded hole on the outer wall of the connecting block 2, the right end of the fixing screw 610 passes through the corresponding connecting hole 609 and is inserted into the threaded hole on the outer wall of the connecting block 2. By rotating the fixing screw 610, the fixing screw 610 is tightened into the threaded hole on the outer wall of the connecting block 2, thereby fixing the position of the rotating disk 608, thus restricting the adjustment column 606 from continuing to rotate, and facilitating the fixing of the position of the clamping plate 603, so that the device is clamped and fixed on the bed board of the medical bed 1.
