Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a tracheal blocking device. Background Art

[0002] Tracheotomy is a common emergency technique in clinical practice. It is usually performed when the airway is blocked or when the patient cannot breathe normally. By cutting the trachea in the patient's neck and inserting the tracheotomy tube into the trachea, the patient can be provided with a direct breathing channel, thereby ensuring the supply of oxygen and avoiding respiratory failure. After the patient's condition stabilizes and respiratory function recovers, the tracheotomy tube will be removed. However, before the tube is removed, a trial of blocking the tube must be performed to encourage the patient to establish a normal airway ventilation mode, that is, breathing through the mouth and nose, and no longer relying on the tracheotomy tube at the tracheotomy site to breathe, to ensure that the patient's cardiopulmonary function can function normally after the tracheotomy tube is removed.

[0003] At present, there is no unified and matching special tube plugging device for patients with tracheotomy who need to plug the tube. Medical staff in various departments often make their own tube plugging devices using local materials, and then plug the self-made tube plugging devices from the inside or outside of the end of the tracheotomy tube to achieve the plugging operation of the tracheotomy tube. The materials of the self-made tube plugging device include: fat emulsion amino acid glucose injection dosing port, Murphy dropper, heparin cap, disposable drainage bag, enteral nutrition infusion device protective cap, syringe piston head, infusion soft bag, cork, application film, disposable latex urinary catheter valve segment, disposable ventilator circuit extension tube cap and gastric tube cap, etc.

[0004] However, the self-made tube plugging device made of the above materials usually visually inspects the inner or outer diameter of the cannula, and then repeatedly debugs it on site to meet the requirements for tube plugging. Both the outer and inner plugging tubes completely block the artificial airway. However, for some patients who have had a long tracheotomy, due to the long-term use of artificial airways for breathing, a one-time complete blockage of the artificial airway can easily cause patients to have difficulty breathing, decreased pulmonary ventilation function, and hypoxemia, and even suffocation in severe cases. If necessary, a second tracheotomy is required, which not only increases the patient's pain, but the second tracheotomy is often more difficult and risky than the first one. Summary of the invention

[0034] The present invention provides a tracheal blocking device, which is combined with Figures 1 to 17 The present invention is described with reference to the structural schematic diagram of FIG.

[0035] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Tracheotomy is a common emergency technique in clinical practice. It is usually performed when the airway is blocked or when the patient cannot breathe normally. By cutting the trachea in the patient's neck and inserting the tracheotomy tube into the trachea, the patient can be provided with a direct breathing channel, thereby ensuring the supply of oxygen and avoiding respiratory failure. After the patient's condition stabilizes and respiratory function recovers, the tracheotomy tube will be removed. However, before the tube is removed, a trial of blocking the tube must be performed to encourage the patient to establish a normal airway ventilation mode, that is, breathing through the mouth and nose, and no longer relying on the tracheotomy tube at the tracheotomy site to breathe, to ensure that the patient's cardiopulmonary function can function normally after the tracheotomy tube is removed.

[0037] At present, there is no unified and matching special tube plugging device for patients with tracheotomy who need to plug the tube. Medical staff in various departments often make their own tube plugging devices using local materials, and then plug the self-made tube plugging devices from the inside or outside of the end of the tracheotomy tube to achieve the plugging operation of the tracheotomy tube. The materials of the self-made tube plugging device include: fat emulsion amino acid glucose injection dosing port, Murphy dropper, heparin cap, disposable drainage bag, enteral nutrition infusion device protective cap, syringe piston head, infusion soft bag, cork, application film, disposable latex urinary catheter valve segment, disposable ventilator circuit extension tube cap and gastric tube cap, etc.

[0038] However, the self-made tube plugging device made of the above materials usually visually inspects the inner or outer diameter of the cannula, and then repeatedly debugs it on site to meet the requirements for tube plugging. Both the outer and inner plugging tubes completely block the artificial airway, and the standardization and safety of medical operations are not guaranteed. However, for some patients with a long tracheotomy time, due to the long-term use of artificial airways for breathing, a one-time complete blockage of the artificial airway can easily cause patients to have difficulty breathing, decreased pulmonary ventilation function, and hypoxemia, and even suffocation in severe cases. If necessary, a second tracheotomy is required, which not only increases the patient's pain, but also the second tracheotomy is often more difficult and risky than the first one.

[0039] In addition, the success rate of homemade pipe plugging devices is not ideal, and it is not conducive to the patient's recovery. In severe cases, improper material handling of homemade products may cause iatrogenic tracheal foreign bodies or infections, and the patient experience is poor. Based on the above problems, the present invention provides a tracheal pipe plug, which is used in conjunction with the annular adjustment plate, three arc control plates and annular fixing plate of the progressive blocking assembly through a gear adjustment sleeve. Air flows into the tracheotomy tube from the air flow ports on the inner sides of the three arc control plates. The annular adjustment plate is used to drive the three arc control plates to rotate synchronously. The end of the arc control plate away from the annular adjustment plate slides along the arc groove, so that the arc control plate moves to the side close to or away from the center line of the gear adjustment sleeve, thereby adjusting the size of the air flow ports on the inner sides of the three arc control plates, and realizing progressive pipe plugging of the tracheotomy tube, which can be beneficial to disease recovery and smooth extubation. The tracheal pipe plug of the present invention has good effect, is easy to use, has strong practicality, and is worthy of promotion.

[0040] Reference Figure 1 and Figure 8 , Figure 1 This is a three-dimensional diagram of the pipe plugging device of this embodiment. Figure 8 FIG. 1 is an exploded view of the pipe plugging device of this embodiment. Figure 1 , 8 As shown, a tracheal pipe blocking device includes a gear adjustment sleeve 1 and a progressive blocking component arranged on the gear adjustment sleeve 1, one end of the gear adjustment sleeve 1 is detachably sealed and connected to the tracheotomy sleeve 10, and the progressive blocking component includes an annular adjustment plate 4 coaxially arranged in the gear adjustment sleeve 1, the outer side of the annular adjustment plate 4 abuts against the inner wall of the gear adjustment sleeve 1, and the annular adjustment plate 4 is slidably connected to the gear adjustment sleeve 1 along its circumferential direction, referring to Fig.10 and Fig.11 , Fig.10 This is a schematic diagram of the internal unsealed state of the pipe plugging device of this embodiment. Fig.11 Schematic diagram of the internal full plugging of the pipe plugging device of this embodiment. Fig.10 , 11 As shown, three arc control plates 2 are arranged in a surrounding manner at equal intervals in the gear adjustment sleeve 1, and adjacent arc control plates 2 overlap and abut each other head to tail, and the inner sides of the three arc control plates 2 constitute air circulation openings, one end of the arc control plate 2 is hinged to the annular adjustment plate 4, and the hinge axis is parallel to the center line of the gear adjustment sleeve 1, and the annular fixing plate 3 is coaxially fixed in the gear adjustment sleeve 1, and is located on the side of the arc control plate 2 away from the annular adjustment plate 4, and three arc chute grooves 31 are opened in a surrounding manner at equal intervals on the annular fixing plate 3, and the other end of the arc control plate 2 slides along the arc chute 31, and the annular adjustment plate 4 drives the three arc control plates 2 to rotate synchronously, so that the side of the arc control plate 2 away from the annular adjustment plate 4 moves toward or away from the center line of the gear adjustment sleeve 1, and the size of the air circulation openings on the inner sides of the three arc control plates 2 are adjusted.

[0041] After the tracheal tube blocker in this embodiment is connected to the tracheotomy tube 10 using the gear adjustment sleeve 1, medical staff can use the annular adjustment plate 4 to drive the three arc control plates 2 to rotate synchronously. Since one end of the arc control plate 2 is hinged to the annular adjustment plate 4, and the other end slides along the arc slide groove 31 of the annular fixing plate 3, the three arc control plates 2 can move from the side away from the annular adjustment plate 4 to the side close to or away from the center line of the gear adjustment sleeve 1 when following the synchronous rotation of the annular adjustment plate 4, thereby adjusting the size of the air circulation openings on the inner sides of the three arc control plates 2. The arc control plate 2 is the main component for changing the size of the air circulation opening, thereby realizing progressive tube blocking of the tracheotomy tube 10, thereby improving the patient's comfort and tolerance.

Figure 4 As shown, as a further optimization scheme, in this embodiment, a gear adjustment groove 11 is opened on the gear adjustment sleeve 1 along its circumference, the gear adjustment groove 11 is coaxial with the center line of the gear adjustment sleeve 1, and a gear controller 8 is passed through the gear adjustment groove 11, one end of the gear controller 8 is fixedly connected to the annular adjustment plate 4, and the other end extends to the outside of the gear adjustment sleeve 1.

[0043] In this embodiment, by opening a gear adjustment groove 11 on the gear adjustment sleeve 1, the gear controller 8 can be used to drive the annular adjustment plate 4 to rotate around its circumference, thereby driving the three arc control plates 2 to rotate synchronously, so that the arc control plate 2 moves away from the side of the annular adjustment plate 4 to the side close to or away from the center line of the gear adjustment sleeve 1, and the size of the air circulation openings on the inner sides of the three arc control plates 2 are adjusted. The pipe plugging device of the present invention adopts the industry's first gear adjustment method. Compared with the direct contact between medical staff and the air intake adjustment components during the operation of the existing pipe plugging device, the present pipe plugging device adopts an indirect contact method. Medical staff control the opening and closing hole distance of the three arc control plates 2 by contacting the gear controller 8 on the outer wall of the pipe plugging device, thereby controlling the air intake volume. It is easy to use, clean and hygienic, and improves the standardization and safety of pipe plugging operations.

[0044] As a further optimization solution, in this embodiment, the outer side of the gear adjustment sleeve 1 is provided with scales along its circumference, and the scales are located on one side of the gear adjustment groove 11 .

[0045] In this embodiment, a scale is set on one side of the gear adjustment groove 11 of the gear adjustment sleeve 1, which is convenient for medical staff to perform progressive tube blocking according to the patient's condition. If it is promoted, it will further realize the standardized technical implementation of tube blocking for clinical tracheotomy patients, accelerate patient recovery, have social benefits, and be able to standardize the process and method of tube blocking for clinical tracheal intubation patients, ensure disease recovery and smooth extubation, and at the same time avoid insufficient air intake leading to dyspnea, decreased pulmonary ventilation function and hypoxemia, etc., thereby further improving the safety of tube blocking.

This material is clinically safe and standardized, with suitable models, proper fixation, repeated disinfection, safety, and not easy to slip or get infected. The tube plug product of the present invention has a smooth surface, is lightweight, and can be sterilized under high pressure. The size matches the outer diameter of the tracheotomy tube 10 (international unified specifications), which not only standardizes clinical tube plug supplies but also ensures clinical safety. It only needs to be gently stuck on the tracheotomy tube 10 to complete the tube plugging operation. The method is simple and easy to master. The surface of the tube plug is smooth, which can effectively prevent the occurrence of iatrogenic tracheal foreign bodies or infections caused by the retention of material residues.

[0070] This tube blocking device is suitable for all patients with tracheotomy who meet the tube blocking conditions (direct complete tube blocking and gradual tube blocking). By adjusting the size of the air flow openings on the inner side of the three arc-shaped control panels 2, the patient's tube can be completely blocked or gradually blocked. After the patient's tube is blocked, observe the changes in respiratory rate, rhythm, and blood oxygen saturation, and adjust the size of the air flow opening based on the patient's self-feeling and comfort, so as to improve the success rate of tube blocking, improve the patient's tube blocking experience, and standardize industry operating supplies.

[0071] Tracheotomy is a common emergency technique in clinical practice. After the patient's condition stabilizes and respiratory function is restored, the tracheotomy tube will be removed, but a trial of tube blocking must be performed before the tube is removed. Currently, there is no unified tube blocking device in clinical practice. Various materials are used for tracheal tube blocking, including fat emulsion amino acid (17) glucose (11%) injection dosing port, Murphy dropper, heparin cap, disposable drainage bag, enteral nutrition infusion device protective cap, syringe piston head, infusion soft bag, cork, application film, disposable latex urinary catheter valve section, disposable ventilator circuit extension tube cap and gastric tube cap, etc. However, these materials have the problems of complicated production, various styles, poor connection with the tracheotomy tube diameter, and great difficulty in progressive tube blocking operation.

[0072] To solve the above problems, we proposed a tracheal tube plugging device. The device has been clinically practiced and discussed in terms of materials, structure, model, operating specifications and usage methods, solving the current urgent and necessary product uniformity and safety issues. The device can achieve a progressive external tube plugging operation mode, which is suitable for all tracheotomy patients who need tube plugging, improving patient comfort and tube plugging success rate. The outer wall of the device has scales, the diameter of the plugging can be adjusted, and the operation is simple and easy, which can be quickly promoted in the industry.

[0073] This tube plugging device is specially used for tracheotomy. The outer wall of the tube plugging device is marked with scales, and it can perform progressive tube plugging on tracheotomy patients. Clinical data is easy to count, achieving a unified combination of scientificity, safety, and patient comfort, which can accelerate the rapid recovery of patients. In addition, by marking the gear position on the scale, the standardization of progressive tube plugging adjustment is further improved.

[0074] This tube plugger uses more optimized materials. Compared with the universal tracheotomy tube plugger, it has a more flexible and simple mechanical structure, can freely adjust the size of the air inlet channel and is easy to fix. It is tightly connected with the tracheotomy tube and is not easy to slip.

[0075] The tube plugging device adopts an external plugging method, which can not only adapt to the plugging of tracheotomy tubes with different inner diameters, but also be sleeved on the outside of the tracheotomy tube, thereby reducing the risk of slippage and infection and improving safety.

[0076] The tube blocking device can flexibly adjust the air intake area to block the tube during the pre-blocking process of tracheotomy patients, reduce discomfort and failure rate during the blocking process, achieve progressive blocking, and increase the blocking success rate as well as patient tolerance and comfort.

[0077] During use, the clinical manifestations of patients with progressive tube occlusion are observed, and the operating data is convenient for observation and statistics, achieving a unified combination of scientificity, safety, and patient comfort, and accelerating the rapid recovery of patients.

[0078] The pipe plugging device of the present invention has a strict mechanical structure. With the help of the lever principle in physics, the rotating annular adjustment plate can be regarded as a force arm, the gear fixing button can be regarded as a fulcrum, and the arc control plate can be regarded as a load. By adjusting the angle (gear) of the arc control plate on the annular adjustment plate, the gear fixing button is driven to rotate in the arc control plate, and then the arc control plates are driven to rotate relative to each other, so as to realize the change of the opening and closing angle of the air flow port.

[0079] The tube blocking device of the present invention can achieve 0°-360° full-range progressive tube blocking during the patient's tracheal intubation in clinical practice, and realize flexible control of the oxygen supply in and out according to the patient's recovery status. The gear controller is used to control the size of the opening and closing area between the arc control plates, that is, the area of ​​the tube blocking air intake, according to the gear toggle (angle) in the gear adjustment slot. The zero gear is full tube blocking, the fifth gear is no tube blocking, and the remaining gears are progressive tube blocking.

[0080] The anti-reversal filling sleeve 61 in the tube blocking device of the present invention can ensure that it is effectively and tightly connected with the tracheotomy sleeve 10 and is not easy to fall out.

[0081] The pipe plugging device of the present invention seals the outside of the tracheotomy tube. If internal sealing is performed, the connection portion between the pipe plugging device and the tracheotomy tube can be adjusted accordingly according to the different tracheotomy tubes.

[0085] 2. Specific implementation process

[0086] 1. For patients with stable clinical conditions, small amounts of sputum, good swallowing and coughing abilities, and no obvious airway obstruction, adjust the tube blocking device to zero position to achieve full tube blocking measures.

[0087] 2. For tracheotomy patients who have been wearing the tube for a long time and are severely dependent on the open airway and have difficulty in extubation, progressive extubation can be used. Medical staff can flexibly adjust the tube blocking device from the first to the third gear to achieve progressive tube blocking measures based on the patient's clinical symptoms.

[0088] 3. Observe the effect

[0090] 2. The patient's oxygen saturation and oxygen partial pressure;

[0091] 3. Observe the patient's cough and sputum;

[0092] 4. Monitor the patient’s vital signs.

[0093] IV. Emergency Plan

[0094] 1. When the whole tube is blocked, the patient can directly remove the occluder if he cannot tolerate it. The adjustable / progressive tube blocker can be tightly connected with the tracheotomy tube and is not easy to fall out. It can also be removed in an emergency to restore the original tracheotomy state.

[0095] 2. The material used in this plugger can be disinfected. If the plugger accidentally falls off during use, it can be replaced with a new one and used alternately with the old one after disinfection measures.
