Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an area-gradual tracheotomy tube blocking device. Background Art

[0002] Tracheotomy is a common emergency surgical procedure for rescuing critically ill patients with upper airway obstruction and lower airway secretion retention. After tracheotomy, it can effectively improve the patient's inefficient respiratory morphology, promote the discharge of sputum, reduce the patient's respiratory dead space, reduce the incidence of lung infection, and help accelerate the patient's recovery process. However, the opening of the airway deprives the airway of its gas heating and humidification function, weakening the airway's defense function. In addition, it can suppress the cough reflex and even pose risks such as tracheotomy infection and aphonia. Therefore, tracheotomy patients should be extubated as soon as possible after meeting the conditions for extubation.

[0003] The consensus on tracheotomy extubation clearly states that patients should undergo progressive occlusion. However, progressive occlusion by area is poorly implemented clinically. Currently, there is a lack of suitable progressive occlusion devices, and this approach can only be performed empirically. For example, these devices use infusion set regulating valves or cut-to-size existing occlusion devices. These devices are unable to achieve precise progressive occlusion, potentially interfering with physicians' clinical decisions and affecting the success rate of tracheotomy extubation.

[0004] Therefore, in order to solve the above-mentioned problems, the present invention provides a tracheotomy tube blocking device with progressive area. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide an area-progressive tracheotomy tube blocking device to solve the current technical problem that it is impossible to accurately and progressively block the patient's tube, which may interfere with the doctor's clinical decision-making and thus affect the success rate of the patient's tracheotomy and extubation.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: designing an area progressive tracheotomy tube blocking device, comprising a mounting frame, a connecting pipe fixedly mounted on the side of the mounting frame, and a fixed sleeve fixedly connected to the side of the connecting pipe away from the mounting frame;

[0007] The first blocking plate, the second blocking plate, the third blocking plate, the fourth blocking plate and the fifth blocking plate are detachably mounted inside the mounting frame through a snap-fit ​​assembly;

[0008] The sides of the first blocking plate and the second blocking plate, the second blocking plate and the third blocking plate, the third blocking plate and the fourth blocking plate, and the fourth blocking plate and the fifth blocking plate are connected by a rotating assembly;

[0009] Limiting components are provided on the sides of the first blocking plate, the second blocking plate, the third blocking plate, the fourth blocking plate and the fifth blocking plate.

[0010] Preferably, the limiting assembly includes a limiting disc and a limiting column, the top of the first blocking plate and the third blocking plate, the third blocking plate and the fourth blocking plate, the fourth blocking plate and the fifth blocking plate are all vertically fixed with connecting columns, the top surface of each connecting column is fixedly installed with a limiting disc, the top of the third blocking plate, the third blocking plate and the fourth blocking plate, the fourth blocking plate and the fifth blocking plate are all provided with a fixing groove, and the inner side wall of each fixing groove is fixedly installed with a limiting column.

[0011] Preferably, the rotating assembly includes a rotating block and a sliding block, and the sides of the third blocking plate, the third blocking plate and the fourth blocking plate, and the fourth blocking plate and the fifth blocking plate are all provided with mounting grooves, and the inner side wall of each mounting groove is rotatably mounted with a rotating rod through a bearing, and the middle end surface of each rotating rod is fixedly sleeved with a rotating block, and the rotating block is rotatably mounted inside the mounting groove.

[0012] Preferably, sliding blocks are fixedly installed on the surfaces of both ends of the side edges of the first blocking plate, the second blocking plate, the third blocking plate and the fourth blocking plate, and sliding slots are opened inside the two ends of the side edges of each rotating block, and the sliding blocks are slidably inserted into the sliding slots.

[0013] Preferably, the snap-on assembly includes a snap-on sleeve and a connecting rod, a connecting block is fixedly installed on one side of the inner side wall of the mounting frame close to the connecting tube, and the number of connecting blocks is several groups, each of the side surfaces of the connecting blocks is fixedly installed with a fixing block, and a connecting rod is fixedly installed between the sides of each two groups of the fixing blocks.

[0014] Preferably, a clamping sleeve is fixedly installed on one side of the side of the first blocking plate, the second blocking plate, the third blocking plate, the fourth blocking plate and the fifth blocking plate close to the connecting pipe, and the clamping sleeve is movably sleeved on the outside of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model is provided with multiple groups of fan-shaped blocking plates inside the installation frame, and fixed grooves are opened on the sides of the blocking plates, multiple groups of limiting columns are provided in the fixing grooves, and connecting columns and limiting discs are provided at the same position on the other side of the blocking plates. Then, two adjacent groups of blocking plates are rotatably connected by rotating rods and rotating blocks between the two adjacent groups of blocking plates. When it is necessary to gradually adjust the open pipe blocking area inside the installation frame, it is only necessary to rotate and fold the multiple groups of blocking plates relative to each other inside the installation frame, so that after the first blocking plate is rotated and folded to the top surface of the second blocking plate, the first blocking plate and the second blocking plate are then simultaneously folded. The cam is rotated and folded to the top surface of the third blocking plate, and then the connecting column and the limiting disc are inserted into the fixed groove, so that the limiting disc is elastically deformed by the side of the limiting column, and the limiting disc can move to the bottom of the outer side of the limiting column, so that the limiting disc loses the resistance force of the limiting column and is deformed and restored. The bottom surface of the limiting column can be fitted with the top surface of the limiting disc and is subjected to a resistance and limiting treatment, so that multiple groups of blocking plates can be stably fitted together, and the number of rotation and folding of the blocking plates can be adjusted to achieve gradual adjustment of the internal open area of ​​the side of the mounting frame, thereby improving the success rate of tracheotomy and extubation of patients.

[0017] 2. The utility model provides an arc-shaped connecting rod on the side of the installation frame and a clamping sleeve on the side of the blocking plate, so that when the blocking plate is adjusted and installed, it is only necessary to push and pull the blocking plate to drive the blocking plate to rotate inside the installation frame so that the clamping sleeve on the side is clamped and sleeved into the outside of the connecting rod, thereby allowing the blocking plate to be quickly fixed and adjusted, ensuring that the blocking plate will not arbitrarily move away from the inside when blocking the open area of ​​the installation frame, thereby affecting the accurate and progressive tube blocking of the patient.

[0026] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A progressive tracheotomy tube blocking device, see Figures 1 to 4 The side of the mounting frame 1 is fixedly installed with a connecting pipe 11, and the side of the connecting pipe 11 away from the mounting frame 1 is fixedly connected with a fixed sleeve 12. The inside of the mounting frame 1 is movably and detachably installed with a first blocking plate 13, a second blocking plate 14, a third blocking plate 15, a fourth blocking plate 16 and a fifth blocking plate 17 through a snap-fit ​​assembly. The sides of the first blocking plate 13 and the second blocking plate 14, the second blocking plate 14 and the third blocking plate 15, the third blocking plate 15 and the fourth blocking plate 16, and the fourth blocking plate 16 and the fifth blocking plate 17 are connected by a rotating assembly. The sides of the first blocking plate 13, the second blocking plate 14, the third blocking plate 15, the fourth blocking plate 16 and the fifth blocking plate 17 are all provided with a limiting assembly. By arranging multiple groups of rotatable and foldable blocking plates inside the mounting frame 1, the blocking plates can be pushed in sequence to cause them to rotate and overlap, and the number of rotation and folding of the blocking plates can be adjusted to achieve progressive adjustment of the internal open area of ​​the side of the mounting frame 1, thereby improving the success rate of tracheotomy and extubation of patients.

[0028] For details, see Figures 1 to 4 The limiting assembly includes a limiting disc 22 and a limiting column 23. The top of the first blocking plate 13 and the bottom of the third blocking plate 15, the third blocking plate 15 and the fourth blocking plate 16, the fourth blocking plate 16 and the fifth blocking plate 17 are all vertically fixed with a connecting column 21, and the top surface of each connecting column 21 is fixedly installed with a limiting disc 22. The top of the third blocking plate 15, the third blocking plate 15 and the fourth blocking plate 16, the fourth blocking plate 16 and the fifth blocking plate 17 are all provided with a fixing groove 2, and the inner side wall of each fixing groove 2 is fixedly installed with a limiting column 23. By arranging the limiting column 23 and the limiting disc 22 inside the blocking plate, the blocking plate can be overlapped and fixed after the blocking plate is rotated and folded, so as to avoid arbitrary dispersion of the blocking plate after rotation and folding, which affects the progressive adjustment of the opening area.

[0029] For further information, see Figures 1 to 4The rotating assembly includes a rotating block 32 and a sliding block 33. The third blocking plate 15, the third blocking plate 15 and the fourth blocking plate 16, the fourth blocking plate 16 and the fifth blocking plate 17 are all provided with mounting grooves 3 on their sides. A rotating rod 31 is rotatably mounted on the inner side wall of each mounting groove 3 through a bearing. A rotating block 32 is fixedly sleeved on the middle end surface of each rotating rod 31, and the rotating block 32 is rotatably mounted inside the mounting groove 3. The rotating block 32 is rotatably mounted inside the blocking plate by rotating the rotating rod 31, so that the blocking plate can be pushed to drive the rotating block 32 to rotate and fold synchronously.

[0030] It is worth noting that, see Figures 1 to 4 The first blocking plate 13, the second blocking plate 14, the third blocking plate 15 and the fourth blocking plate 16 are fixedly mounted with sliding blocks 33 on both ends of the side surfaces, and each of the rotating blocks 32 is provided with a sliding slot 34 at both ends of the side, and the sliding block 33 is slidably inserted into the sliding slot 34. By providing the sliding block 33 on the side of the blocking plate, it is slidably inserted into the sliding slot 34, and then the blocking plate can be pulled to move vertically to adjust the distance between the two adjacent groups of blocking plates, while ensuring the normal rotation and folding between the adjacent blocking plates.

[0031] It is worth noting that see Figures 1 to 4 The clamping assembly includes a clamping sleeve 43 and a connecting rod 41. A connecting block 42 is fixedly installed on the side of the inner wall of the installation frame 1 close to the connecting pipe 11, and the number of the connecting blocks 42 is several groups. A fixing block 4 is fixedly installed on the side surface of each connecting block 42, and a connecting rod 41 is fixedly installed between the sides of each two groups of the fixing blocks 4. By providing an arc-shaped connecting rod 41 on the inner side of the installation frame 1, the clamping sleeve 43 connecting the blocking plate to its side can be sleeved on the outside of the connecting rod 41 to improve the blocking plate's sealing treatment of the open position of the installation frame 1.

[0032] It is worth mentioning that see Figures 1 to 4 The first blocking plate 13, the second blocking plate 14, the third blocking plate 15, the fourth blocking plate 16 and the fifth blocking plate 17 are all fixedly installed with a clamping sleeve 43 on one side close to the connecting pipe 11, and the clamping sleeve 43 is movably sleeved on the outside of the connecting rod 41. By providing a clamping sleeve 43 at the bottom of the first blocking plate 13, the second blocking plate 14, the third blocking plate 15, the fourth blocking plate 16 and the fifth blocking plate 17, the clamping sleeve 43 can be pressed down and sleeved on the outside of the connecting rod 41 to achieve the installation and fixing of the blocking plate.

[0033] When the first stop plate 13 is in operation, the first stop plate 13 is pulled and the clamping sleeve 43 below it is disengaged from the surface of the fixing rod, and the first stop plate 13 is pushed, so that after the sliding block 33 is pressed against the inside of the sliding slot 34, the sliding block 33 drives the rotating block 32 to rotate synchronously in the installation slot 3, and then the top surface of the first stop plate 13 can be fitted with the top surface of the second stop plate 14 after being rotated and flipped. Then, the connecting post 21 and the limiting disc 22 are vertically inserted into the fixing slot 2, so that the limiting disc 22 can move vertically and fit the outer side of the limiting post 23 located inside the fixing frame, so that the outer side of the limiting post 23 can fit the outer side wall of the limiting disc 22. As the first stop plate 13 is rotated and folded, the outer side of the limiting post 23 can press against the outer side of the limiting disc 22 to cause it to deform, so that the limiting disc 22 can be removed from the sides of the multiple groups of limiting posts 23. After the limiting disc 22 loses its resistance, the limiting disc 22 elastically recovers its shape. At this time, the limiting post 23 is located above the limiting disc 22 and acts on it to limit its position, thereby engaging and limiting the first blocking plate 13 to prevent it from arbitrarily separating from the surface of the second blocking plate 14. Then, according to use needs, after the second blocking plate 14 is pushed to connect with the first blocking plate 13, the second blocking plate 14 is pulled to drive the side from the sliding block 33 to move vertically from the inside of the sliding slot 34, and then the second blocking plate 14 is pushed again to repeat the above operation steps, so that the first blocking plate 13 and the second blocking plate 14 can be synchronously rotated and folded to be placed on the top surface of the third blocking plate 15, thereby increasing the open area of ​​the side of the installation frame 1. Then, according to needs, the fourth blocking plate 16 and the fifth blocking plate 17 are pushed to gradually change the open area inside the installation frame 1, thereby improving the success rate of tracheotomy and extubation of the patient.
