Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a tracheal tube structure for patients with endotracheal intubation. Background Technology

[0002] In mechanical ventilation, one-piece molded 90-degree plastic elbows are often used to replace ventilator extension tubing during the weaning transition for intubated or endotracheally cut patients to reduce dead space. However, the traditional one-piece molded 90-degree plastic elbow, with only openings at both ends, has a significant drawback: during airway suctioning, the entire elbow assembly must be disassembled, resulting in airway opening and disruption of the airtight seal. This frequent disconnection not only increases the workload of healthcare workers but also significantly increases the risk of airway exposure for patients, becoming a major contributing factor to infectious complications such as hospital-acquired pneumonia. Although elbows now feature an additional nozzle with a protective cap (e.g., as disclosed in Chinese patent document CN201275348Y), to ensure the stability of the cap installation, most protective caps are installed on the nozzle using a tight snap-fit ​​or threaded connection. This requires a large force to be applied to the elbow and the cap when opening and closing, which can cause vibration of the endotracheal tube. This can lead to strain on the tracheostomy incision, causing significant discomfort to the patient and posing a safety hazard.

[0003] Therefore, it is essential to design a tracheal tube structure for weaning patients from T-tubes and suctioning sputum to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and deficiencies, and to provide a tracheal tube structure for suctioning sputum after T-tube weaning intubated patients. The suction port of this tracheal tube structure can not only be opened for suctioning, but also achieve a good sealing effect when sealing is required. Moreover, the vibration caused by the opening and closing process of the suction port is very small, which can help reduce the chance of tearing of the incision. This not only reduces the patient's discomfort, but also helps to improve safety.

[0005] The technical solution of this utility model is implemented as follows: An endotracheal tube structure for suctioning sputum after T-tube weaning intubated patients includes a curved tube with a suction port on it, the inner hole of which is directly connected to the inner hole of the inner end of the curved tube. The structure is characterized by further including a sealing assembly, which comprises a hollow soft ball and at least three elastic plates. One end of each elastic plate is embedded in the wall of the hollow soft ball, and the ends of the elastic plates are connected together. The elastic plates are arranged in a ring array around the inner hole of the hollow soft ball. The hollow soft ball is placed in the suction port, and the other end of each elastic plate is outside the suction port. The outer wall of the hollow soft ball can expand and seal the suction port due to the elastic force of the elastic plates.

[0006] Preferably, a reinforcing convex ring is provided on the outer circumferential surface of the outer end of the suction tube opening.

[0007] Preferably, the elastic sheet includes an inner arc-shaped sheet and an outer arc-shaped sheet with opposite bending directions. One end of the inner arc-shaped sheet is connected to one end of the outer arc-shaped sheet by a circular arc transition. The inner arc-shaped sheet is embedded in the wall of the hollow soft ball, and the inner arc-shaped surface of the inner arc-shaped sheet faces the inner hole.

[0008] Preferably, the hollow soft ball has a constriction opening on its surface facing the suction tube opening, and the elastic sheets are arranged around the constriction opening.

[0009] Preferably, the hollow soft ball is a polyurethane hollow soft ball or a polyester hollow soft ball.

[0010] Preferably, the inner hole of the suction tube opening is a spherical inner hole that matches the expanded hollow soft ball.

[0011] The beneficial effects of this utility model are as follows: The endotracheal tube structure adopts a sealing component including a hollow soft ball and at least three elastic sheets. This sealing component can not only reliably seal the suction tube opening, but also easily open the suction tube opening. Moreover, the vibration generated during the opening and closing of the suction tube opening by such a sealing component is very small, and medical staff do not need to directly touch the curved tube with their hands. This can help reduce the chance of tearing of the patient's incision, which can not only reduce the patient's discomfort, but also improve safety. Attached Figure Description

[0020] like Figures 1 to 4 As shown, the present invention discloses a tracheal catheter structure for weaning T-tube patients from endotracheal intubation and suctioning, comprising a curved tube 1, wherein a suction port 11 is provided on the curved tube 1, and the inner hole of the suction port 11 is directly connected to the inner hole of the inner end of the curved tube 1. To achieve the purpose of the present invention, a sealing component 2 is also included. The sealing component 2 comprises a hollow soft ball 21 and at least three elastic plates 22. One end of each elastic plate 22 is embedded in the ball wall 211 of the hollow soft ball 21, and one end of each elastic plate 22 is connected together. The elastic plates 22 are arranged in a ring array around the inner hole 212 of the hollow soft ball 21, and each elastic plate 22 can elastically support the hollow soft ball 21. The hollow soft ball 21 is placed in the suction port 11, and the other end of each elastic plate 22 is placed outside the suction port 11. The outer wall of the hollow soft ball 21 can expand and seal the suction port 11 by the elastic action of each elastic plate 22.

[0021] The endotracheal tube structure employs a sealing component 2, which includes a hollow soft ball 21 and at least three elastic sheets 22. This sealing component 2 not only provides a reliable seal for the suction tube opening 11, but also allows for easy opening of the suction tube opening 11. Furthermore, the vibration generated during the opening and closing of the suction tube opening 11 by this sealing component 2 is minimal, and medical staff do not need to directly contact the curved tube 1 with their hands. This reduces the likelihood of tearing at the patient's incision, thereby reducing patient discomfort and improving safety.

[0022] like Figure 1 , Figure 2 , Figures 6 to 8As shown, each elastic piece 22 generates an elastic force around the hollow soft ball 21, causing the hollow soft ball 21 to move away from the inner hole 212. This elastic force causes the hollow soft ball 21 to expand, allowing its outer wall to adhere tightly to the suction tube opening 11, thus effectively sealing the suction tube opening 11. When it is necessary to open the suction tube opening 11, a finger is applied to the other end of each elastic piece 22 to move the elastic piece 22 closer to the center of the suction tube opening 11. This causes the hollow soft ball 21 to contract, allowing its outer wall to detach from the suction tube opening 11. The sealing component 2 can then be pulled out of the suction tube opening 11, making it easy and quick to open the suction tube opening 11. Because the sealing assembly 2 uses the compression of each elastic sheet 22 toward the center of the suction tube opening 11 to detach the hollow soft ball 21 from the wall of the suction tube opening 11, pressing each elastic sheet 22 can effectively reduce the probability of vibration being transmitted to the suction tube opening 11, which can well meet the needs of actual use.

[0023] like Figure 5 As shown, a reinforcing protrusion 12 is provided on the outer circumferential surface of the outer end of the suction tube opening 11. This can improve the structural strength of the suction tube opening 11, which can effectively prevent the suction tube opening 11 from deforming or cracking when the hollow soft ball 21 expands and seals, thus enabling a more stable and reliable sealing effect.

[0024] like Figures 2 to 4 As shown, the elastic sheet 22 includes an inner arc-shaped sheet 221 and an outer arc-shaped sheet 222 with opposite bending directions. One end of the inner arc-shaped sheet 221 and one end of the outer arc-shaped sheet 222 are connected by a rounded transition. The inner arc-shaped sheet 221 is embedded in the spherical wall 211 of the hollow soft sphere 21, with the inner arc-shaped surface of the inner arc-shaped sheet 221 facing the inner hole 212. Such an elastic sheet 22 is very simple and reliable. It is not only easy to manufacture, but also generates a stable and reliable elastic force, and facilitates the operation of medical personnel to compress the elastic sheet 22, thereby helping to further improve the reliability and applicability of the endotracheal tube structure.

[0025] like Figure 2 and Figure 3 As shown, the hollow soft ball 21 has a contraction opening 213 on its surface facing the suction tube opening 11, and the elastic sheets 22 are arranged around the contraction opening 213. This not only controls the amount of raw material used on the hollow soft ball 21, but also provides a convenient movement position for the compression of the elastic sheets 22 and reduces compression resistance by utilizing the contraction opening 213, which helps to further improve the convenience of use.

[0026] The hollow soft ball 21 is a polyurethane hollow soft ball or a polyester hollow soft ball. This not only gives the hollow soft ball 21 a good elastic sealing effect, but also makes it easy to compress, thereby better meeting the needs of actual use and further improving the applicability of the endotracheal tube structure.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, the inner hole of the suction tube opening 11 is a spherical inner hole 111 that matches the expanded hollow soft ball 21. This not only increases the contact area between the hollow soft ball 21 and the inner wall of the suction tube opening 11, but also allows the spherical inner hole 111 to accurately limit the position of the hollow soft ball 21. This enables the sealing component 2 to perform a more stable and comprehensive sealing function, thereby helping to further improve the reliability and applicability of the endotracheal tube structure.

[0028] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
