Description

Technical Field

[0001] This invention relates to the field of stent technology in anesthesiology, and more particularly to a threaded tube stent for anesthesia machines used in critical care anesthesia departments. Background Technology

[0002] Anesthesiology is a science that uses basic theories, clinical knowledge and techniques related to anesthesia to eliminate surgical pain, ensure patient safety and create favorable conditions for surgery. In some surgeries, anesthesia machines are used to anesthetize patients in order to reduce or eliminate the pain they experience during the operation, so that the surgery can proceed smoothly.

[0003] While the threaded tube stents in existing anesthesia machines can effectively fix the threaded tube, the fixation and release procedures are quite cumbersome and time-consuming, thus affecting the efficiency of preoperative preparation. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: although the threaded tube stent in the existing anesthesia machine can effectively fix the threaded tube, the steps of fixing and unfixing are relatively cumbersome and require a lot of time, thus affecting the efficiency of preoperative preparation. Therefore, this invention proposes a threaded tube stent for anesthesia machines used in critical care anesthesia departments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A threaded tube stent for an anesthesia machine used in critical care anesthesia departments, comprising:

[0007] A first rod and a second rod, the second rod is fixedly installed in the first rod by a snap-fit ​​component, and a mounting plate is fixedly installed at the top end of the second rod. A placement platform is fixedly installed on the upper surface of the mounting plate, and a base is fixedly installed at the bottom end of the first rod.

[0008] A positioning assembly is used to fix a threaded tube located on a placement platform. The positioning assembly includes two sets of pressing components and a driving component. The pressing components include pressing rods, and the two pressing rods are used to press and clamp the upper surface of the threaded tube. The driving component is used to provide a driving force for the two pressing rods to move together.

[0009] A first threaded rod is vertically and rotatably installed on the lower surface of the mounting plate. A first slider is threadedly sleeved on the first threaded rod. A stop bar is symmetrically and vertically fixedly installed on the surface of the first slider. The first slider is restricted from rotating by a limiting component. A first adjusting wheel is fixedly sleeved on the end of the first threaded rod away from the mounting plate.

[0010] The pressing component also includes a mounting block, a spring, and a retaining ring. Two mounting blocks are symmetrically fixedly installed on the upper surface of the mounting plate, and each has an installation opening. Two abutting rods are slidably installed in the two installation openings, and both ends of the rods extend out of the mounting blocks. The retaining ring is fixedly sleeved on the abutting rod, and the spring is sleeved on the abutting rod, with both ends fixedly connected to the side walls of the retaining ring and the mounting block, respectively.

[0011] The driving component includes a pressure rod, two movable plates, two connecting rods, and two inclined blocks. The two inclined blocks are respectively fixedly installed on the lower surfaces of the two abutment rods. The two connecting rods are respectively vertically slidably installed in the two mounting openings, and their top ends correspond to the positions of the two inclined blocks. The bottom ends of the two connecting rods respectively protrude from the placement platform and are vertically fixedly connected to the surfaces of the two movable plates. A limit block is fixedly sleeved at one end of the connecting rod located in the mounting opening. Both movable plates are fixedly connected to the surface of the pressure rod.

[0012] The limiting component includes two limiting rods, which are vertically fixedly installed on the lower surface of the mounting plate, and the first slider is slidably sleeved on the two limiting rods;

[0013] A roller is rotatably mounted on the end of the connecting rod away from the moving plate.

[0014] Preferably, the ends of the two abutments that are close to each other are beveled and both are bonded with a rubber layer.

[0015] Preferably, the snap-fit ​​component includes two spring rods, which are symmetrically and vertically fixedly installed on the left and right side walls of the second rod body. The surface of the first rod body is symmetrically provided with multiple snap-fit ​​interfaces that cooperate with the two spring rods. The second rod body releases the snap-fit ​​state between the two spring rods and the snap-fit ​​interfaces through a reset component.

[0016] Preferably, the reset component includes two abutment plates, a second threaded rod, and two second sliders. The upper surface of the base is provided with a sliding groove. The second threaded rod is horizontally rotatably installed in the sliding groove, and the thread directions on the left and right sides are opposite. The two second sliders are symmetrically threaded onto the left and right sides of the second threaded rod, and their upper surfaces are respectively vertically fixedly connected to the two abutment plates through a bearing rod. One end of the second threaded rod passes through the sliding groove and is fixedly fitted with a second adjusting wheel. Multiple protrusions corresponding to the card interface positions are symmetrically and vertically fixedly installed on the side of the two abutment plates that are close to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 0. The two push rods in the pressing component are controlled by the driving component to move horizontally in a direction away from each other. Then the threaded tube to be clamped is placed between the two push rods. At this time, the driving component is released, and the ends of the two push rods that are close to each other will press against the left and right sides of the upper surface of the threaded tube, thereby achieving the effect of clamping and fixing, which is convenient and quick.

[0019] 1. Two sets of pressing components can fix threaded pipes of any size, making the fixing objects no longer limited to a single type, thus increasing the practicality of the device;

[0020] 2. The overall height of the stent can be adjusted by the cooperation between the snap-fit ​​component and the reset component, which increases the flexibility of the stent and makes it easier for medical staff to use. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-6 A threaded tube stent for an anesthesia machine used in critical care anesthesia departments, comprising:

[0030] The first rod 1 and the second rod 2 are fixedly installed inside the first rod 1 by a snap-fit ​​component, and a mounting plate 3 is fixedly installed at the top. A placement platform 4 is fixedly installed on the upper surface of the mounting plate 3, and a base 5 is fixedly installed at the bottom of the first rod 1.

[0031] The positioning assembly is used to fix the threaded tube located on the placement platform 4. The positioning assembly includes two sets of pressing parts 6 and a driving part 7. The pressing parts 6 include pressing rods 61. The two pressing rods 61 are used to press and clamp the upper surface of the threaded tube. The driving part 7 is used to provide a driving force for the two pressing rods 61 to move together.

[0032] A first threaded rod 8 is vertically rotatably mounted on the lower surface of the mounting plate 3. A first slider 9 is threaded onto the first threaded rod 8. A stop bar 10 is symmetrically and vertically fixedly mounted on the surface of the first slider 9. The first slider 9 is restricted from rotating by a limiting component. A first adjusting wheel 14 is fixedly sleeved on the end of the first threaded rod 8 away from the mounting plate 3.

[0033] After the threaded tube is fixed, rotate the first adjusting wheel 14. At this time, the first threaded rod 8 rotates. The first slider 9, which is threaded onto the first threaded rod 8, moves vertically under the action of the limiting component. As a result, the two stop rods 10 fixedly connected to it also move until the two stop rods 10 abut against the surface of the pressure rod 71. This restricts the movement of the pressure rod 71 and prevents medical personnel from squeezing the pressure rod 71 during the work process, which would cause the fixing of the threaded tube to be released.

[0034] In an embodiment of the applied technical solution, the driving component 7 controls the two abutment rods 61 in the pressing component 6 to move horizontally in a direction away from each other. Then, the threaded tube to be clamped is placed between the two abutment rods 61. At this time, the driving component 7 is released, and the ends of the two abutment rods 61 that are close to each other will press against the left and right sides of the upper surface of the threaded tube, thereby achieving the effect of clamping and fixing, which is convenient and quick. When taking it out, it is only necessary to use the driving component 7 again to control the two abutment rods 61 to move away from each other and leave the surface of the threaded tube.

[0035] In this preferred embodiment, the pressing component 6 further includes a mounting block 62, a spring 63, and a retaining ring 64. Two mounting blocks 62 are symmetrically fixedly installed on the upper surface of the mounting plate 3, each with an installation opening 65. Two abutment rods 61 are slidably installed within the two installation openings 65, with both ends extending out of the mounting blocks 62. The retaining ring 64 is fixedly sleeved on the abutment rods 61, and the spring 63 is sleeved on the abutment rods 61, with both ends fixedly connected to the side walls of the retaining ring 64 and the mounting block 62, respectively. When the device is not in operation, the spring 63 is at its original length, and the two abutment rods 61 are close to each other. When clamping the threaded tube, the driving component 7 first drives the two abutment rods 61 to move away from each other. The two abutment rods 61 slide within the two mounting blocks 62 and move away from each other. The abutment rods 61 drive the retaining ring 64 to move, compressing the spring 63. The spring 63 deforms to store energy. When the distance between the two close ends of the two abutment rods 61 reaches the required clamping distance for the threaded tube, the clamping action is completed. When the width is reached, place the threaded tube on the upper surface of the placement platform 4 between the two abutment rods 61, then release the drive component 7. The two springs 63 will release their elastic potential energy and return to their original length. The two springs 63 will drive the two retaining rings 64 to move closer to each other. The two retaining rings 64 will drive the two abutment rods 61 to move closer to each other. In turn, the elastic potential energy of the springs 63 will drive the two ends of the abutment rods 61 to abut against the left and right side walls of the threaded tube, clamping the threaded tube. This is convenient and quick, avoiding the cumbersome steps of fixing and unfixing.

[0036] In this preferred embodiment, the driving component 7 includes a pressure rod 71, two movable plates 72, two connecting rods 73, and two inclined blocks 74. The two inclined blocks 74 are fixedly installed on the lower surfaces of the two abutment rods 61. The two connecting rods 73 are vertically slidably installed in the two mounting openings 65, with their top ends corresponding to the positions of the two inclined blocks 74. The bottom ends of the two connecting rods 73 protrude from the placement platform 4 and are vertically fixedly connected to the surfaces of the two movable plates 72. A limit block 75 is fixedly sleeved at one end of the connecting rod 73 located in the mounting opening 65. Both movable plates 72 are fixedly connected to the surface of the pressure rod 71. When the pressure rod 71 is pulled upwards, the two movable plates 72 move along with the two connecting rods 73 within the mounting openings 65. As the two connecting rods 73 move, they slide into contact with the inclined surfaces of the two inclined blocks 74, causing the inclined blocks 74 to move horizontally away from the two abutment rods 61.

[0037] In this preferred embodiment, the limiting component includes two limiting rods 11, which are vertically fixedly installed on the lower surface of the mounting plate 3. The first slider 9 is slidably sleeved on the two limiting rods 11. Since the first slider 9 is slidably sleeved on the two limiting rods 11, and the positions of the two limiting rods 11 are fixed, when the first threaded rod 8 rotates, the first slider 9 threaded on the first threaded rod 8 can only move in the vertical direction and will not rotate with the first threaded rod 8.

[0038] In this preferred embodiment, the ends of the two abutment rods 61 that are close to each other are beveled, and both are bonded with a rubber layer. The beveled design makes the clamping and pressing operation of the two abutment rods 61 on the threaded tube more stable, while the rubber layer increases the friction between the surface of the threaded tube and the beveled ends of the two abutment rods 61.

[0039] In this preferred embodiment, the locking component includes two spring rods 12, which are symmetrically and vertically fixedly installed on the left and right side walls of the second rod body 2. The surface of the first rod body 1 has multiple symmetrical locking interfaces 13 that mate with the two spring rods 12. The second rod body 2 releases the locking state between the two spring rods 12 and the locking interfaces 13 via a reset component. When the two spring rods 12 enter the two horizontally positioned locking interfaces 13, the position of the second rod body 2 within the first rod body 1 is fixed.

[0040] In this preferred embodiment, the reset component includes two abutment plates 15, a second threaded rod 16, and two second sliders 17. A groove 18 is provided on the upper surface of the base 5. The second threaded rod 16 is horizontally rotatably installed in the groove 18, and the threads on the left and right sides are opposite. The two second sliders 17 are symmetrically threaded onto the left and right sides of the second threaded rod 16, and their upper surfaces are respectively vertically fixed to the two abutment plates 15 through a bearing rod 20. One end of the second threaded rod 16 passes through the groove 18 and is fixedly fitted with a second adjusting wheel 19. Multiple protrusions 21 corresponding to the positions of the card interface 13 are symmetrically and vertically fixed on the side of the two abutment plates 15 that are close to each other. Rotating the second adjusting wheel 19 causes the second threaded rod 16 to rotate, causing the two second sliders 17, which are located in the slide groove 18 and threadedly connected to the left and right sides of the second threaded rod 16, to move horizontally relative to each other, either closer or further apart. The two abutment plates 15, fixedly connected to them via the bearing rod 20, also move together. When the two abutment plates 15 approach each other and the multiple protrusions 21 fixedly mounted on their surfaces enter the multiple locking interfaces 13 corresponding to their positions, the two spring rods 12 located in the locking interfaces 13 are squeezed by the protrusions 21, causing them to contract. At this point, the fixation between the first rod 1 and the second rod 2 is released. The second rod 2 can then be moved upwards or downwards until it reaches the appropriate position. Then, the two abutment plates 15, along with the multiple protrusions 21, are controlled to leave the multiple locking interfaces 13. The force exerted by the protrusions 21 on the ends of the two spring rods 12 disappears, and the two spring rods 12 quickly return to their original position. The two ends that are far apart will then enter the two locking interfaces 13 located on the same horizontal plane to form a locking connection, which is convenient and quick.

[0041] In this preferred embodiment, a roller 22 is rotatably mounted on the end of the connecting rod 73 away from the moving plate 72. The roller 22 reduces the frictional force generated when the end of the connecting rod 73 slides into contact with the inclined surface of the inclined block 74.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
