Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a novel pediatric clinical bronchial support device. Background Technology

[0002] In pediatric clinical intensive care and anesthesia resuscitation, ventilators are widely used. The ventilator tubing typically includes an expiratory bronchus, an inspiratory bronchus, a condensate cup, and a T-connector for the endotracheal tube. In actual nursing care, to prevent condensation from flowing back into the child's airway, medical staff need to ensure the condensate cup in the middle of the tubing is at its lowest position and to keep the proximal end of the tubing connected to the T-connector as stable and horizontal as possible. However, existing clinical bronchial support devices have significant shortcomings in practical application:

[0003] Firstly, existing tubing support devices often only provide single-dimensional flat support or simple suspension, failing to offer precise segmented angle support for complex breathing tubing. Without a proper guiding and support mechanism, when the tubing sags naturally due to gravity, sharp bends can easily form at the junction of horizontal and sloping sections. This not only increases airflow resistance within the tubing, severely impacting the ventilator's ventilation efficiency, but also easily prevents condensate from flowing smoothly down into the condensate cup, increasing the risk of fluid retention and aspiration.

[0004] Secondly, pediatric patients, due to their young age and low cooperation, often exhibit involuntary head movements and turning over while in bed. Currently, most commonly used tube support devices in clinical practice statically lock the tube to the support, lacking dynamic displacement adaptability. In this rigid support state, once the child's head moves, the statically fixed tube cannot move synchronously, inevitably causing a strong reverse traction on the T-connector to the endotracheal tube in the child's throat. This unrelieved pulling not only easily leads to dislodgement of the breathing tube and fatal ventilation interruption, but also causes friction and displacement of the endotracheal tube within the child's airway, causing severe secondary physical damage to the child's delicate airway mucosa, posing a significant clinical safety hazard. Summary of the Invention

[0005] Therefore, it is necessary to provide a novel pediatric clinical bronchial support device to address the existing technical problems.

[0006] To address the problems of existing technologies, the present invention adopts the following technical solution: a novel pediatric clinical bronchial support device, used in conjunction with an expiratory bronchus, an inspiratory bronchus, and a three-way connector, wherein the expiratory bronchus and the inspiratory bronchus are both flexible corrugated tubes with several spaced corrugations formed on their outer walls. The device comprises:

[0007] The support mechanism includes a horizontally arranged support rod and a slide that is slidably connected to the support rod along the axial direction;

[0008] A tube support mechanism, connected to the slide, includes a snap-fit ​​member, a flat support member, and an inclined support member arranged sequentially along the axial direction of the support rod. The snap-fit ​​member is used to horizontally fix the tee connector. The flat support member is used to horizontally support the sections of the expiratory branch tube and the inspiratory branch tube that connect to the tee connector. The inclined support member is used to support the sections of the expiratory branch tube and the inspiratory branch tube that connect to the water collection cup, such that a downward angle greater than 90 degrees is formed between the section of the tube passing through the inclined support member and the section of the tube passing through the flat support member, so as to guide the tube to extend inclinedly toward the water collection cup in a lower position.

[0009] The traction drive mechanism includes an elastic head loop, a traction rope, and an elastic reset member. The two ends of the traction rope are respectively connected to the elastic head loop and the slide. The elastic reset member is disposed on the support rod and acts on the slide. The elastic head loop is used to move with the child's head and pulls the slide through the traction rope to overcome the resistance of the elastic reset member, thereby driving the tube support mechanism to move synchronously.

[0010] Furthermore, the slide includes a limiting slide sleeve and a connecting slide sleeve that are slidably sleeved on the support rod. A connecting rod is provided between the limiting slide sleeve and the connecting slide sleeve to fix them together. The outer wall of the support rod is provided with a first limiting groove extending along its axial direction. The inner wall of the limiting slide sleeve is provided with a first limiting strip that slides in cooperation with the first limiting groove.

[0011] Furthermore, a traction rod perpendicular to the support rod is fixedly provided on the outer wall of the connecting sleeve. An adjusting sleeve is fitted on the traction rod. One end of the traction rope is fixedly connected to the elastic head ring, and the other end is fixedly connected to the adjusting sleeve. The outer wall of the traction rod is provided with a second limiting groove extending along its axial direction. The inner wall of the adjusting sleeve is provided with a second limiting strip that slides in cooperation with the second limiting groove. The adjusting sleeve is provided with a first threaded groove that penetrates its inner and outer walls. A first adjusting bolt that abuts against the outer wall of the traction rod is screwed into the first threaded groove.

[0012] Furthermore, the outer wall of the support rod is provided with a convex ring located between the limiting sleeve and the connecting sleeve, and the elastic reset member is a helical spring sleeved on the support rod, with both ends of the helical spring abutting against the limiting sleeve and the convex ring respectively.

[0013] Furthermore, the snap-fit ​​component is a C-shaped elastic buckle, which is fixedly connected to the connecting sleeve.

[0014] Furthermore, the flat support includes a central seat and two U-shaped support plates. A vertically downward extending rod is fixed on the connecting rod. The central seat is fixedly connected to the extending rod. The two U-shaped support plates are symmetrical and side by side and fixedly connected to the central seat. The opening of each U-shaped support plate faces upward, and the length direction of each U-shaped support plate extends along the axial direction of the support rod.

[0015] Furthermore, an arc-shaped rubber pad is fitted onto the inner surface of each U-shaped tray, and the arc-shaped rubber pad is provided with a plurality of arc-shaped clips equidistantly distributed along the length direction of the U-shaped tray, and each arc-shaped clip is engaged between adjacent corrugations.

[0016] Furthermore, the lower end of the extension rod is fixed with two symmetrical and parallel internally threaded tubes, each internally threaded tube being parallel to the support rod, and each internally threaded tube having a threaded rod screwed in it. The inclined support includes two symmetrical U-shaped support plates, each U-shaped support plate being connected to one end of the corresponding threaded rod via a rotary joint. Each U-shaped support plate is inclined, and its axial extension line intersects with the axial extension line of the U-shaped support plate at an angle greater than 90°.

[0017] Furthermore, a U-shaped rubber sheet is attached to the U-shaped side of each U-shaped support plate, and the U-shaped rubber sheet is inserted between adjacent corrugations. Two symmetrical flexible baffles are connected to the open end of each U-shaped support plate, and the two flexible baffles close the open end of the U-shaped support plate.

[0018] Furthermore, one end of the support rod is fixedly provided with a lifting adjustment rod perpendicular to it, and a mounting rod for external fixation is provided on the side of the lifting adjustment rod. Guide sleeves that are spaced apart from it and axially vertical are fixedly provided on the mounting rod. The lifting adjustment rod is coaxially inserted into the guide sleeve. A third limiting groove is opened on the outer wall of the lifting adjustment rod along its axial direction. A third limiting strip is provided on the inner wall of the guide sleeve that slides with the third limiting groove. A second threaded groove is provided on the guide sleeve that penetrates its inner and outer walls. A second adjusting bolt that abuts against the outer wall of the lifting adjustment rod is screwed into the second threaded groove.

[0019] The beneficial effects of this invention compared to the prior art are:

[0020] This invention provides precise segmented support for the ventilator tubing using snap-fit ​​components, flat supports, and angled supports arranged sequentially along a support rod. The flat supports keep the proximal tubing horizontal to prevent condensation backflow, while the angled supports create a downward angle greater than 90 degrees, effectively preventing sharp bends in the tubing, thus reducing airflow resistance and guiding accumulated water smoothly into the low-level water collection cup. Simultaneously, this invention incorporates a traction drive mechanism connected to the slide. When the child's head moves, the elastic headband pulls the slide and the entire tubing support mechanism along the support rod via a traction rope, overcoming the resistance of the elastic reset component to move synchronously. This effectively eliminates the reverse pulling force of the tubing on the T-connector and endotracheal tube, completely preventing accidental tubing dislodgement and secondary friction damage to the child's airway mucosa. Automatic reset is achieved after the external force is released, greatly improving the safety and stability of pediatric clinical ventilation care. Attached Figure Description

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 10 This diagram illustrates a novel pediatric clinical bronchial support device. Before its actual clinical use, it is necessary to clarify the structure of the ventilator tubing used in conjunction with it. This structure mainly includes the ventilator and two main thick tubes connected to it. These two main thick tubes correspond to the expiratory bronchus 1 and the inspiratory bronchus 2, respectively. Both the expiratory bronchus 1 and the inspiratory bronchus 2 are flexible corrugated tubes, with several spaced corrugations 27 forming on their outer walls. Both the expiratory bronchus 1 and the inspiratory bronchus 2 are divided into two sections. Taking the expiratory bronchus 1 as an example, one end of one section is connected to the ventilator, and the other end is connected to a water collection cup located in the middle of the tubing. One end of the other section is connected to the water collection cup, and the other end is connected to a three-way connector 3. The inspiratory bronchus 2 is also connected to another water collection cup using the same connection method; the three-way connector 3 is a rigid pipe with a built-in one-way valve. When connected to the three-way connector 3, the manifold on the three-way connector 3 will be connected to the intubation tube on the child's throat through a flexible short tube; in actual use, it is necessary to keep the water collection cups on the expiratory bronchus 1 and the inspiratory bronchus 2 at the low position of the entire pipeline, so as to use gravity to collect the exhaled water and the water discharged from the ventilator. At the same time, it is also necessary to keep the section of the expiratory bronchus 1 and the inspiratory bronchus 2 connected to the three-way connector 3 in a horizontal state to prevent water vapor from flowing back into the child's throat.

[0034] To ensure that the aforementioned ventilator tubing can both facilitate smooth fluid collection and flexibly adapt to the child's head movements in practical applications, this device is designed with a support mechanism and a tubing support mechanism, such as... Figure 1As shown, the support mechanism includes a horizontally arranged support rod 4 and a slide 5 slidably connected to the support rod 4 along the axial direction. The support rod 4 provides a horizontal mounting foundation and sliding guide support for the entire device. The slide 5 supports the subsequent structure and allows it to move along the support rod 4. The pipe support mechanism is connected to the slide 5 and moves synchronously with the slide 5, as shown in the diagram. Figure 1 As shown, the tube support mechanism includes a snap-fit ​​component 6, a flat support component 7, and an inclined support component 8 arranged sequentially along the axial direction of the support rod 4. The snap-fit ​​component 6 is used to horizontally fix the tee connector 3, and its function is to keep the tee connector 3 in a stable state to prevent it from falling off. The flat support component 7 is used to horizontally support the sections of the expiratory bronchus 1 and the inspiratory bronchus 2 that connect to the tee connector 3, and its function is to keep this section of the tube horizontal to prevent it from sagging and pulling on the tee connector 3, which could cause secondary damage to the child's throat. The inclined support component 8 is used to support the sections of the expiratory bronchus 1 and the inspiratory bronchus 2 that connect to the water collection cup, so that the section of the tube passing through the inclined support component 8 and the section of the tube passing through the flat support component 7 form a downward angle greater than 90 degrees, so as to guide the tube to extend tilted towards the water collection cup in a lower position. This angle design can ensure smooth gas flow, and at the same time, use gravity to smoothly drain the condensate into the water collection cup.

[0035] To ensure the pipeline is securely supported and water is effectively drained, and to effectively handle involuntary head movements of the child and prevent pulling on the pipeline, this device is designed with a traction drive mechanism. For example... Figure 1 and Figure 5 As shown, the traction drive mechanism includes an elastic headband 9, a traction rope 10, and an elastic reset component. The two ends of the traction rope 10 are connected to the elastic headband 9 and the slide 5, respectively, which transmits the pulling force from the head to the slide 5. The elastic reset component is located on the support rod 4 and acts on the slide 5, which accumulates potential energy and provides automatic restoring force after the external force disappears. The elastic headband 9 is used to put on the child's head and moves with the child's head, thereby sensing the child's movements such as head shaking and turning over. It also pulls the slide 5 through the traction rope 10 to overcome the resistance of the elastic reset component and slide, thereby driving the tube support mechanism to move synchronously. The function of this linkage process is to ensure that the connection between the three-way connector 3 and the child's laryngeal tube will not be broken or pulled on the affected area due to the child's body movements, thus providing all-round protection for the child.

[0036] To ensure that the carriage 5 can slide smoothly and without deflection when subjected to the tension of the traction rope 10, such as Figure 3 and Figure 7 As shown, the slide 5 includes a limiting slide sleeve 11 and a connecting slide sleeve 12 slidably sleeved on the support rod 4. The purpose of using two slide sleeves is to provide two-point support and prevent the slide 5 from tilting or jamming during sliding. A connecting rod 13 is provided between the limiting slide sleeve 11 and the connecting slide sleeve 12 to fix them together. The function of the connecting rod 13 is to ensure that the two slide sleeves can move synchronously as a whole frame; at the same time, as Figure 4As shown, the outer wall of the support rod 4 is provided with a first limiting groove 14 extending along its axial direction, and the inner wall of the limiting sleeve 11 is provided with a first limiting strip 15 that slides in cooperation with the first limiting groove 14. The nested cooperation between the first limiting groove 14 and the first limiting strip 15 effectively prevents the limiting sleeve 11 and the entire slide 5 from rotating around the support rod 4, ensuring the absolute consistency and stability of the pipeline sliding direction.

[0037] Based on the smooth sliding characteristics of the slide 5, in order to further meet the different needs of children of different body types or sleeping positions for the direction of traction force and connection position, such as Figure 1 and Figure 5 As shown, a traction rod 16 perpendicular to the support rod 4 is fixedly provided on the outer wall of the connecting sleeve 12. The function of the traction rod 16 is to provide an offset connection fulcrum for the traction rope 10. An adjusting sleeve 17 is fitted on the traction rod 16, which allows for relative sliding adjustment of the traction fulcrum along the length of the traction rod 16. One end of the traction rope 10 is fixedly connected to the elastic head ring 9, and the other end is fixedly connected to the adjusting sleeve 17. Figure 6 As shown, the outer wall of the traction rod 16 is provided with a second limiting groove 18 extending along its axial direction, and the inner wall of the adjusting sleeve 17 is provided with a second limiting strip 19 that slides in conjunction with the second limiting groove 18. The function of the two is to prevent the adjusting sleeve 17 from rotating under tension. The adjusting sleeve 17 is provided with a first threaded groove penetrating its inner and outer walls. A first adjusting bolt 20 that abuts against the outer wall of the traction rod 16 is screwed into the first threaded groove. Its function is to firmly lock the adjusting sleeve 17 to the desired position on the traction rod 16 by tightening the friction force. In addition, as Figure 3 and Figure 7 As shown, the outer wall of the support rod 4 is provided with a protruding ring 21 located between the limiting sleeve 11 and the connecting sleeve 12. The elastic reset component is a helical spring 22 sleeved on the support rod 4. The two ends of the helical spring 22 abut against the limiting sleeve 11 and the protruding ring 21 respectively. The function of the protruding ring 21 is to provide a fixed abutting surface for the helical spring 22, so that the helical spring 22 can be compressed under the pushing of the limiting sleeve 11 to realize the potential energy accumulation of the reset function.

[0038] To ensure accurate and reliable installation of the tee fitting 3 and its connected piping, such as Figure 3 and Figure 6 As shown, the snap-fit ​​component 6 uses a C-shaped elastic snap-fit ​​23, which is fixedly connected to the connecting sleeve 12. The function of the elastic snap-fit ​​23 is to use its own elastic deformation to achieve quick insertion and clamping fixation of the tee connector 3; as shown Figure 3 and Figure 10As shown, the flat support 7 includes a central seat 24 and two U-shaped support plates 25. A vertically downward extension rod 26 is fixed on the connecting rod 13. Its function is to reduce the overall height of the flat support 7 so that it can adapt to the natural low position of the clinical tubing. The central seat 24 is fixedly connected to the extension rod 26 to support and distribute the weight of the tubing. The two U-shaped support plates 25 are symmetrical and fixedly connected to the central seat 24 side by side. Their function is to support the expiratory bronchus 1 and the inspiratory bronchus 2 independently and without interference. The opening of each U-shaped support plate 25 faces upward, and the length direction of each U-shaped support plate 25 extends along the axial direction of the support rod 4 to ensure that the tubing is placed stably and maintains a straight horizontal extension.

[0039] After the flat support 7 successfully maintained the horizontal orientation of the tubing section, considering that both the expiratory branch tube 1 and the inspiratory branch tube 2 used in practice are flexible corrugated tubes with undulations, in order to further enhance the axial anti-slip capability of the tubing within the support plate, such as... Figure 9 and Figure 10 As shown, each U-shaped support plate 25 has an arc-shaped rubber pad 28 fitted onto its inner surface. This pad increases flexible contact cushioning and prevents hard wear on the pipe wall. The arc-shaped rubber pad 28 has several arc-shaped retaining strips 29 evenly distributed along the length of the U-shaped support plate 25. Each retaining strip 29 is engaged between adjacent corrugations 27, using mechanical embedding resistance to prevent accidental axial movement of the flexible corrugated pipe within the U-shaped support plate 25. Simultaneously, as... Figure 10 As shown, the lower end of the extension rod 26 is fixed with two symmetrically arranged internally threaded tubes 30, each parallel to the support rod 4. Each internally threaded tube 30 contains a threaded rod 31. The inclined support 8 includes two symmetrically arranged U-shaped support plates 32. Each U-shaped support plate 32 is connected to one end of the corresponding threaded rod 31 via a rotary joint 33. The function of the threaded rod 31 cooperating with the rotary joint 33 is to allow independent adjustment of the longitudinal extension distance of the U-shaped support plate 32. Figure 3 and Figure 7 As shown, each U-shaped support plate 32 is inclined, and its extended axis intersects with the extended axis of the U-shaped support plate 25 at an angle greater than 90°. Its function is to support the drooping pipe section with a gentle transition obtuse angle, ensuring unobstructed internal gas flow and allowing accumulated water to flow naturally downwards. It should be noted that the U-shaped support plate 25 and U-shaped support plate 32 are different from the C-shaped elastic buckle 23. The openings of the U-shaped support plate 25 and U-shaped support plate 32 are wide and straight, so they will not cause compression to the internal pipes during disassembly, assembly, and placement.

[0040] To prevent the pipeline from radially popping out or sliding down the slope when it is tilted, such as Figure 8 and Figure 10As shown, each U-shaped support plate 32 has a U-shaped rubber sheet 34 attached to its U-shaped side. The U-shaped rubber sheet 34 is inserted between adjacent corrugations 27. Its function is to increase the friction of the fit and firmly grip the corrugation 27 structure, preventing the expiratory bronchus 1 and inspiratory bronchus 2, which are in an inclined state, from sliding down under the action of gravity. At the same time, each U-shaped support plate 32 has two symmetrical flexible baffles 35 connected to its open end. The two flexible baffles 35 close the open end of the U-shaped support plate 32. Its function is to effectively prevent the tubing from sliding up from the open end of the inclined U-shaped support plate 32 while allowing medical staff to press down to insert the tubing, thereby completely locking the position of the entire tubing.

[0041] To ensure that the entire device can be precisely height-adjusted according to actual clinical needs, such as Figure 1 and Figure 2 As shown, a lifting adjustment rod 36 perpendicular to the support rod 4 is fixed at one end. The function of the lifting adjustment rod 36 is to drive the entire device to move vertically. A mounting rod 37 for external fixation is provided on the side of the lifting adjustment rod 36. The mounting rod 37 facilitates fixing the device to external facilities such as hospital beds or medical supports using external clamps. Guide sleeves 38, spaced apart and axially vertical, are fixed on the mounting rod 37. These guide sleeves provide a vertical sliding guide channel for the lifting adjustment rod 36. The lifting adjustment rod 36 is coaxially inserted into the guide sleeves 38. Furthermore... The outer wall of the lifting adjustment rod 36 is provided with a third limiting groove 39 along its axial direction. The inner wall of the guide sleeve 38 is provided with a third limiting strip 40 that slides with the third limiting groove 39. The function of the two is to prevent the lifting adjustment rod 36 from rotating left and right in the guide sleeve 38, and to ensure that the working orientation of the entire device is absolutely stable. The guide sleeve 38 is provided with a second threaded groove that runs through its inner and outer walls. A second adjusting bolt 41 that abuts against the outer wall of the lifting adjustment rod 36 is screwed into the second threaded groove. The function of the second adjusting bolt 41 is to lock the adjusted device height firmly by manually screwing in and tightening the lifting adjustment rod 36.

[0042] In summary, this novel pediatric clinical bronchial support device not only successfully achieves anti-slip fixation and reasonable tilting drainage of the tubing, but also endows the entire tubing system with intelligent adaptive capability that moves synchronously with the child's head movement, greatly improving the safety and convenience of clinical nursing.

[0043] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
