Abstract

This invention relates to the field of medical device technology and discloses a positioning aid for respiratory endoscopy nursing, comprising a main body and a retractable plate. The retractable plate is fixedly connected to the bottom of the main body, and a limiting frame is fixedly connected to the top of the main body. The top of the limiting frame has a through hole and a sliding hole, which is opened through the central axis of the retractable plate. Retractable grooves are located on the left and right sides of the main body, and sliding grooves are located on the left and right sides of the retractable grooves. This invention extends the push bar to abut against the guardrail, thereby pushing the guardrail out between the retractable plate and the main body. The round rod slides inside the sliding groove, and the connecting plate slides inside the retractable groove. This avoids the situation where the guardrail is completely retracted between the retractable plate and the main body, making it impossible to find a force point to pull the guardrail out, and prevents the guardrail from getting stuck inside the positioning bed. At the same time, it reduces the steps of pulling out the guardrail, making it easier to pull out and increasing the practicality of the device.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a positioning aid for respiratory endoscopy nursing. Background Technology

[0002] During a bronchoscopy, some patients may require local anesthesia for various reasons and then lie on a specially designed bed for the procedure. However, a positioning aid for bronchoscopy care is needed to facilitate the doctor's examination.

[0003] However, the guardrails of the endoscopic positioning bed are usually retracted on both sides of the bed to facilitate the patient lying directly on the bed. When the patient is under local anesthesia and lying on the bed, it is generally necessary to manually pull the guardrails outward. Not only is it difficult to find a point of force to pull the guardrails out because the guardrails are retracted inside the positioning bed, causing the guardrails to get stuck inside the positioning bed, but medical staff also generally need to go through three steps when pulling the guardrails out, flipping the guardrails, and fixing the guardrails. This makes the operation of the device cumbersome, resulting in low practicality of the device. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning aid for respiratory endoscopy nursing, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a positioning aid for respiratory endoscopy nursing, comprising a main body and a retractable plate. The retractable plate is fixedly connected to the bottom of the main body, and a limiting frame is fixedly connected to the top of the main body. The limiting frame has a through hole at its top. The invention also includes:

[0007] A sliding hole is formed through the central axis of the shrink plate;

[0008] Shrinkage grooves are located on the left and right sides of the main body.

[0009] The chutes are located on the left and right sides of the contraction groove;

[0010] The guardrail mechanism is located on the left and right sides of the main body. The guardrail mechanism includes a round rod that is slidably connected inside a groove, and a connecting plate is fixedly connected to the outer wall of the round rod.

[0011] A reclining mechanism is located on the top of the main body. The reclining mechanism includes a stabilizing rod, which is inserted into the top of the main body. A placement plate is fixedly connected to the top of the stabilizing rod.

[0012] The pushing mechanism is located at the bottom of the main body. The pushing mechanism includes an insert block, which is fixedly connected to the bottom of the placement plate at a position corresponding to the through hole. Two elastic steel bars are fixedly connected to the bottom of the insert block. A slide is fixedly connected to the end of the elastic steel bars away from the insert block. A push block is fixedly connected to the side of the slide away from the elastic steel bars. An extension push bar is fixedly connected to the side of the push block away from the slide.

[0013] Furthermore, an electric actuator is fixedly connected to the bottom of the main body. The output end of the electric actuator slides through the main body and the limiting frame. The top of the output end of the electric actuator is spherical. Four support legs are fixedly connected to the bottom of the main body. The four support legs are evenly distributed on the side wall of the main body. Through holes penetrate the limiting frame and the main body. Sliding holes are set correspondingly to the through holes. A gap is left between the top of the shrink plate and the bottom of the main body. There are four shrink grooves, which are distributed correspondingly to the four support legs. There are two sliding grooves, which are symmetrically distributed with the shrink grooves as the center.

[0014] Furthermore, the guardrail mechanism also includes a guardrail plate, which is fixedly connected to the end of the connecting plate away from the round rod. The connecting plate is slidably connected to the inner wall of the shrinkage groove, and the outer wall of the guardrail plate is slidably connected between the shrinkage plate and the main body. There are two guardrail mechanisms, which are symmetrically distributed around the main body.

[0015] Furthermore, the reclining mechanism also includes fitting holes, which are opened on the top of the reclining plate. There are four stabilizing rods, which are evenly distributed at the four corners of the reclining plate and are inserted into the top of the main body. Compression springs are fixedly connected to the bottom of the reclining plate at the four locations corresponding to the stabilizing rods.

[0016] Furthermore, an adjustment mechanism is provided inside the fitting hole. The adjustment mechanism includes an adjustment plate, which is rotatably connected to the inner walls on both sides of the fitting hole. An extension plate is fixedly connected to the left and right sides of the adjustment plate. The bottom central axis of the adjustment plate has grooves that are mutually opened and used in conjunction with the output end of the electric push rod. A neck pillow is fixedly connected to the top of the adjustment plate.

[0017] Furthermore, two elastic steel bars are symmetrically distributed around the insert block, with the outer wall of the insert block inserted into the inner wall of the through hole, the outer wall of the elastic steel bar abutting against the inner wall of the through hole, the outer wall of the slide frame slidingly connected to the inner wall of the slide hole, and the extended push bar distributed between the shrink plate and the main body, with the side of the extended push bar away from the push block abutting against the outer wall of the guardrail.

[0018] Furthermore, a retraction mechanism is provided at the bottom of the carriage. The retraction mechanism includes a limit block, which is fixedly connected to the bottom of the carriage. A stop bar is fixedly connected to the side of the limit block away from the carriage. A telescopic groove is provided on the side of the stop bar away from the limit block. An opening groove is provided at the top of the stop bar corresponding to the telescopic groove.

[0019] Furthermore, a positioning mechanism is provided inside the telescopic groove. The positioning mechanism includes a compression spring, which is fixedly connected to the rear wall of the telescopic groove. A slide rod is fixedly connected to the end of the compression spring away from the rear wall of the telescopic groove. The slide rod is slidably connected to the inner wall of the telescopic groove. A positioning support is rotatably connected to the outer wall of the slide rod away from the compression spring. A compression block is fixedly connected to the end of the positioning support away from the slide rod. The positioning support is engaged with the opening groove.

[0020] The present invention has the following beneficial effects:

[0021] (1) When the patient lies on the placement board, the placement board is subjected to gravity, which compresses the compression spring, thereby causing the stabilizing rod to sink at the top of the main body. At the same time as the placement board presses down, it causes two elastic steel bars to be squeezed between the shrink plate and the main body. This causes the two elastic steel bars to drive the two slides to slide to both sides inside the sliding hole, thereby causing the two extended push bars to slide to both sides of the sliding hole. By abutting against the guardrail, the guardrail is pushed out between the shrink plate and the main body, allowing the round rod to slide inside the sliding groove and the connecting plate to slide inside the shrink groove. This avoids the situation where the guardrail is completely retracted between the shrink plate and the main body and cannot find a force point to pull it out, thus avoiding the phenomenon of the guardrail getting stuck inside the positioning bed. At the same time, it reduces the steps of pulling out the guardrail, making it easier to pull out the guardrail and increasing the practicality of the device.

[0022] (2) When the round rod moves to the outermost end of the slide groove with the guardrail, the guardrail can be flipped up directly, so that the guardrail can stand up to protect the two sides of the main body. During the movement of the slide, the limiting block and the abutment strip will slide at the bottom of the shrink plate, so that the limiting block and the abutment strip will move out of the bottom of the shrink plate. After the guardrail is standing up, the positioning support only needs to be rotated so that the abutment at the top of the positioning support is at the top. After the positioning support is rotated, the sliding rod is pulled by the compression spring inside the expansion groove, so that the sliding rod shrinks inside the expansion groove. At the same time, the positioning support slides inside the opening groove, so that the abutment at the top of the positioning support abuts against the outer wall of the guardrail, thereby positioning the guardrail and preventing the guardrail from turning over during the protection process.

[0023] (3) When the placement plate of the present invention is subjected to pressure and drops, it is finally supported by the bottom of the placement plate through the limiting frame. During the bronchoscopy examination, the doctor controls the electric push rod by stepping on the controller on the ground, so that the output end of the sliding hole moves up and down at the top of the limiting frame. Since the output end of the electric push rod is spherical, it can move inside the groove when the output end of the electric push rod is raised and lowered, thereby driving one end of the adjustment plate to rotate inside the fitting hole, so that one end of the neck pillow is raised, thereby adjusting the patient's position through the doctor's control. This makes it convenient for the doctor to adjust the position according to the patient's body shape. At the same time, the doctor can change the patient's position in real time during the examination to conduct a more accurate examination. Compared with general automated positioning aids, this device has a simple structure, is easy to operate, and has a lower cost.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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] Example 1

[0038] Please see Figures 1-8 As shown, the present invention is a positioning aid for respiratory endoscopy nursing, including a main body 1 and a retractable plate 101, the retractable plate 101 being fixedly connected to the bottom of the main body 1, and further including:

[0039] A sliding hole 102 is formed through the central axis of the shrink plate 101;

[0040] Shrinkage grooves 106 are provided on the left and right sides of the main body 1. There are four shrinkage grooves 106, and the four shrinkage grooves 106 are distributed corresponding to the four support legs 105.

[0041] The slide 107 is provided on the left and right sides of the contraction groove 106. There are two slides 107, which are symmetrically distributed with the contraction groove 106 as the center.

[0042] The top of the main body 1 is fixedly connected to the limiting frame 104. When the placement plate 302 is subjected to pressure and descends, it finally abuts against the bottom of the placement plate 302 through the limiting frame 104, thereby supporting the placement plate 302. The top of the limiting frame 104 is provided with a through hole 108, which passes through the limiting frame 104 and the main body 1. The sliding hole 102 is provided corresponding to the through hole 108. The top of the retractable plate 101 and the bottom of the main body 1 are left with a gap, so that the guardrail plate 203 can be retracted into the gap left between the top of 101 and the bottom of the main body 1.

[0043] Guardrail mechanism 2 is located on the left and right sides of the main body 1. Guardrail mechanism 2 includes a round rod 201, which is slidably connected inside the slide groove 107. A connecting plate 202 is fixedly connected to the outer wall of the round rod 201. Guardrail mechanism 2 also includes a guardrail plate 203, which is fixedly connected to the end of the connecting plate 202 away from the round rod 201. The connecting plate 202 is slidably connected to the inner wall of the shrinkage groove 106. The outer wall of the guardrail plate 203 is slidably connected between the shrinkage plate 101 and the main body 1. There are two guardrail mechanisms 2, which are symmetrically distributed around the main body 1. When the round rod 201 moves to the outermost end of the slide groove 107 with the guardrail plate 203, the guardrail plate 203 can be flipped up by directly pushing it upward, so that the guardrail plate 203 stands up to protect the two sides of the main body 1.

[0044] The reclining mechanism 3 is located on the top of the main body 1. The reclining mechanism 3 includes a stabilizing rod 301, which is inserted into the top of the main body 1. A placement plate 302 is fixedly connected to the top of the stabilizing rod 301. The reclining mechanism 3 also includes a fitting hole 303, which is opened on the top of the placement plate 302. There are four stabilizing rods 301, which are evenly distributed at the four corners of the placement plate 302 and are inserted into the top of the main body 1. Compression springs 304 are fixedly connected to the bottom of the placement plate 302 at four locations corresponding to the stabilizing rods 301. When the patient lies on the placement plate 302, the placement plate 302 is subjected to gravity, which will compress the compression springs 304, thereby causing the stabilizing rods 301 to sink down on the top of the main body 1. At the same time as the placement plate 302 presses down, it will cause two elastic steel bars 502 to be squeezed between the shrink plate 101 and the main body 1.

[0045] The pushing mechanism 5 is located at the bottom of the main body 1. The pushing mechanism 5 includes an insertion block 501, which is fixedly connected to the bottom of the placement plate 302 at a point corresponding to the through hole 108. Two elastic steel bars 502 are fixedly connected to the bottom of the insertion block 501. A slide 503 is fixedly connected to the end of the elastic steel bar 502 away from the insertion block 501. A push block 504 is fixedly connected to the side of the slide 503 away from the elastic steel bar 502. An extension push bar 505 is fixedly connected to the side of the push block 504 away from the slide 503. The two elastic steel bars 502 are symmetrically distributed around the insertion block 501. The outer wall of the insertion block 501 is perpendicular to the through hole 108. The inner wall of the 08 is inserted, the outer wall of the elastic steel strip 502 abuts against the inner wall of the through hole 108, the outer wall of the slide 503 is slidably connected to the inner wall of the slide hole 102, the extension push bar 505 is distributed between the shrink plate 101 and the main body 1, the side of the extension push bar 505 away from the push block 504 abuts against the outer wall of the guardrail 203, the two elastic steel strips 502 drive the two slides 503 to slide to both sides inside the slide hole 102, thereby driving the two extension push bars 505 to slide to both sides of the slide hole 102, and the extension push bar 505 abuts against the guardrail 203, thereby pushing the guardrail 203 out between the shrink plate 101 and the main body 1.

[0046] In use, when the patient lies on the placement board 302, the placement board 302, under the influence of gravity, compresses the compression spring 304, causing the stabilizing rod 301 to sink at the top of the main body 1. Simultaneously, the placement board 302 presses down, causing the two elastic steel bars 502 to compress between the retraction plate 101 and the main body 1. This, in turn, causes the two elastic steel bars 502 to slide the two slide frames 503 to slide to both sides inside the sliding hole 102, thereby causing the two extension push bars 505 to slide to both sides of the sliding hole 102. The extension push bars 505 then abut against the guardrail plate 203, pushing the guardrail plate 203 outwards. Between the retractable plate 101 and the main body 1, the round rod 201 slides inside the slide groove 107, and the connecting plate 202 slides inside the retractable groove 106. This avoids the guardrail 203 from being unable to find a force point to pull out because the guardrail 203 is retracted between the retractable plate 101 and the main body 1, thus preventing the guardrail 203 from getting stuck inside the positioning bed. When the round rod 201 moves with the guardrail 203 to the outermost end of the slide groove 107, the guardrail 203 can be directly pushed upward to flip it over, thereby making the guardrail 203 stand up to protect both sides of the main body 1.

[0047] Example 2

[0048] Please see Figures 1-8As shown, an electric push rod 103 is fixedly connected to the bottom of the main body 1. The output end of the electric push rod 103 slides through the main body 1 and the limiting frame 104. The top of the output end of the electric push rod 103 is spherical. Four support legs 105 are fixedly connected to the bottom of the main body 1. The four support legs 105 are evenly distributed on the side wall of the main body 1. The electric push rod 103 is controlled by the doctor stepping on the controller on the ground, so that the output end of the sliding hole 102 moves up and down on the top of the limiting frame 104. Since the output end of the electric push rod 103 is spherical, it can move inside the groove 403 when the output end of the electric push rod 103 is raised and lowered.

[0049] An adjustment mechanism 4 is provided inside the fitting hole 303. The adjustment mechanism 4 includes an adjustment plate 401, which is rotatably connected to the inner walls on both sides of the fitting hole 303. An extension plate 402 is fixedly connected to the left and right sides of the adjustment plate 401. Abutment grooves 403 are opened on the bottom central axis of the adjustment plate 401. The abutment grooves 403 are used in conjunction with the output end of the electric push rod 103. A neck pillow 404 is fixedly connected to the top of the adjustment plate 401. One end of the adjustment plate 401 is rotated inside the fitting hole 303, causing one end of the neck pillow 404 to tilt up, thereby adjusting the patient's position under the control of the doctor.

[0050] The bottom of the slide 503 is provided with a retraction mechanism 6. The retraction mechanism 6 includes a limit block 601, which is fixedly connected to the bottom of the slide 503. A stop bar 603 is fixedly connected to the side of the limit block 601 away from the slide 503. A telescopic groove 602 is opened on the side of the stop bar 603 away from the limit block 601. An opening groove 604 is opened at the top of the stop bar 603 corresponding to the telescopic groove 602. When the slide 503 moves, it will drive the limit block 601 and the stop bar 603 to slide at the bottom of the retraction plate 101, so that the limit block 601 and the stop bar 603 move out of the bottom of the retraction plate 101. When the guardrail 203 is erected, only the positioning support 703 needs to be rotated.

[0051] The telescopic groove 602 is equipped with a positioning mechanism 7, which includes a compression spring 701. The compression spring 701 is fixedly connected to the rear wall of the telescopic groove 602. A slide rod 702 is fixedly connected to the end of the compression spring 701 away from the rear wall of the telescopic groove 602. The slide rod 702 is slidably connected to the inner wall of the telescopic groove 602. A positioning support 703 is rotatably connected to the outer wall of the slide rod 702 away from the compression spring 701. A compression block is fixedly connected to the end of the positioning support 703 away from the slide rod 702. 703 engages with the opening slot 604, and the positioning support 703 is rotated so that the abutment at the top of the positioning support 703 is positioned at the top. After the positioning support 703 rotates, the compression spring 701 pulls the slide rod 702 inside the telescopic groove 602, causing the slide rod 702 to retract inside the telescopic groove 602. At the same time, the positioning support 703 slides inside the opening slot 604, so that the abutment at the top of the positioning support 703 abuts against the outer wall of the guardrail 203, thereby positioning the guardrail 203.

[0052] During use, as the slide 503 moves, it causes the limiting block 601 and the abutment strip 603 to slide at the bottom of the contraction plate 101, moving them out of the bottom of the contraction plate 101. Once the guardrail 203 is erected, the positioning support 703 is rotated so that the abutment at the top of the positioning support 703 is positioned upwards. When the positioning support 703 rotates, the compression spring 701 pulls the slide rod 702 inside the telescopic groove 602, causing the slide rod 702 to contract inside the telescopic groove 602. Simultaneously, this causes the positioning support 703 to slide inside the opening slot 604, causing the abutment at the top of the positioning support 703 to abut against the outer wall of the guardrail 203, thus positioning the guardrail 203 and preventing it from slipping. During the protective process, the guardrail 203 reverses. When the placement plate 302 is subjected to pressure and drops, it finally abuts against the bottom of the placement plate 302 through the limiting frame 104, thereby supporting the placement plate 302. During the bronchoscopy, the doctor controls the electric actuator 103 by stepping on the controller on the ground, so that the output end of the sliding hole 102 moves up and down at the top of the limiting frame 104. Since the output end of the electric actuator 103 is spherical, it can move inside the groove 403 when the output end of the electric actuator 103 is raised and lowered, thereby driving one end of the adjusting plate 401 to rotate inside the fitting hole 303, causing one end of the neck pillow 404 to tilt up, thereby adjusting the patient's position through the doctor's control.
