Description

Technical Field

[0001] The utility model relates to medical devices, in particular to a connecting device for an artificial airway and a nebulizer. Background Art

[0002] An artificial airway refers to an airway established by medical staff through methods such as endotracheal intubation and tracheotomy when a patient has difficulty breathing, which is called an artificial airway. The artificial airway can effectively ensure the ventilation function of the patient and save the patient's life. Clinically, the methods for establishing an artificial airway include endotracheal intubation or tracheotomy. The establishment of an artificial airway can not only improve the patient's breathing, but also be connected to a ventilator, enabling some patients with difficulty breathing to maintain their respiratory function through mechanical ventilation.

[0003] At present, most of the nebulizers used in hospitals are bite-type or only for connecting to ventilators. When performing nebulization treatment on patients who have been weaned but do not meet the extubation conditions (patients with tracheotomy, endotracheal intubation through the mouth / nose), the nebulizer cannot be well connected to the above pipelines, resulting in waste of liquid medicine or frequent detachment of the nebulizer.

[0004] After retrieval, a Chinese patent application with the application number 202120298602.5 discloses a connecting tube for an artificial airway and a nebulizer, which mainly consists of a three-way tube. Among them, the three-way tube is a threaded tube. The upper end of the three-way tube is provided with an artificial airway connection port, the lower end is provided with a nebulizer connection port, the side of the three-way tube is provided with an air outlet, and a partition with an "L" cross-section is provided in the pipeline of the three-way tube corresponding to the air outlet, and both side edges of the partition are connected to the inner wall of the pipeline. The connecting tube for the artificial airway and the nebulizer of the utility model also has the advantages of simple structure, convenient use, reasonable design, remarkable effect, safety and reliability, and can reduce the workload of nursing staff. However, this connecting tube cannot adjust the oxygen delivery rate according to the needs of the patient during oxygen inhalation, thereby affecting the treatment effect of the patient. Summary of the Utility Model

[0005] Aiming at the technical problems in the prior art that the nebulizer and the artificial airway are not well connected, resulting in frequent tube detachment, and the connecting tube cannot adjust the oxygen delivery rate.

[0006] Technical idea: Starting from the problems of the prior art, this application provides a new connecting device for an artificial airway and a nebulizer. Through a double-chamber connecting tube, the oxygen delivered and the exhaled gas can have their own channels, which will not affect the inhalation of oxygen nebulization; and the setting of the adjustment mechanism on the connecting tube can realize the adjustment of the delivery rate of the nebulized gas.

[0007] To achieve the above object, the technical solution adopted by the utility model is:

[0008] The present application provides a connection device between an artificial airway and a nebulizer, including a connecting tube for connecting with the artificial airway. The tail of the connecting tube forms two non - communicating chambers. A regulating mechanism for regulating the delivery rate of the atomized gas is communicated and arranged in the middle of the connecting tube, and a nebulizer connector is arranged at the head of the connecting tube.

[0009] As an example, the nebulizer connector is a hard - tube cylindrical connector or can also be a threaded connector.

[0010] Specifically, the chambers formed at the tail of the connecting tube are respectively an air - inlet chamber and an air - outlet chamber. A one - way air - inlet valve is arranged in the air - inlet chamber, a one - way air - outlet valve is arranged in the air - outlet chamber, and an air - outlet hole penetrating to the outside is opened on the wall of the air - outlet chamber.

[0011] It should be noted that the tail end of the connecting tube is connected to the artificial airway through a detachable connecting joint. One end of the connecting joint matches the tail end of the connecting tube, and the other end matches the artificial airway. The connecting joint is replaceable, which is convenient for connecting artificial airways with different apertures.

[0012] Furthermore, the regulating mechanism includes a regulating box communicated with the connecting tube. Through - holes communicated with the connecting tube are opened on the front and rear side surfaces of the regulating box. A rotating plate is connected in the regulating box through an adjusting knob, and a plurality of atomizing holes with different aperture sizes are arranged on the rotating plate.

[0013] It should be noted that the regulating box is of a cylindrical structure, and a rotating plate is rotationally matched inside. The atomizing holes with different aperture sizes are arranged on the rotating plate in a clockwise order from large to small. The regulating box is rotationally connected with the adjusting knob, and the rotating plate is fixedly connected with the adjusting knob.

[0014] Even further, the fixing mechanism includes a fixing plate. An installation hole connecting the connecting tube is opened at the center of the fixing plate, and fixing belts are connected to both sides of the fixing plate.

[0015] Specifically, the fixing plate is of an arc - shaped structure, which can better fit the face or the neck. The fixing belts are tied to the back of the head or the neck for fixation.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, two non - communicating air - inlet chambers and air - outlet chambers are arranged at the tail of the connecting tube, and a one - way air - inlet valve and a one - way air - outlet valve are respectively arranged in the air - inlet chamber and the air - outlet chamber, so that the delivered atomized gas and the exhaled gas have their respective channels, which will not affect the inhalation of the atomized gas, and thus ensure the efficiency of gas atomization.

[0018] 2. The utility model facilitates the connection between the connecting pipe and the atomizer by arranging an atomizer connector at the head of the connecting pipe, avoiding the technical problem of frequent pipe detachment during the atomization process due to insecure connection of the atomizer.

[0019] 3. The utility model facilitates the regulation of the delivery rate of the atomizing gas by arranging a regulation mechanism in the middle of the connecting pipe. By rotating the adjustment knob, the rotating piece arranged in the adjustment box is driven to rotate, so that atomizing holes with different aperture sizes correspond to the through holes on the adjustment box, thereby realizing the technical effect that the atomizing gas enters the regulation box from the connecting pipe, reaches the through holes through the atomizing holes, and finally enters the human body through the connecting pipe.

[0020] 4. The utility model installs and fixes the connecting pipe through the installation hole opened at the center of the fixing piece, and further fixes it by surrounding the fixing belts on both sides of the fixing piece around the patient's head or behind the neck, realizing the technical effect of fixing the connecting pipe and making the whole device more stable.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] The inventor has found in clinical practice that most of the nebulizers currently used in hospitals are of the mouthpiece type or are only used to connect to a ventilator. When nebulization treatment is performed on patients who have been taken off the ventilator but have not reached the conditions for extubation and still have an artificial airway, the nebulizer cannot be well connected to the artificial airway connecting tube, resulting in a waste of liquid medicine or frequent detachment of the nebulizer; and during the nebulization process, the input rate of the nebulizing gas cannot be adjusted according to the needs of the patient, resulting in various problems such as reduced nebulization efficacy or discomfort for the patient.

[0032] Based on the above findings, the present application provides a connecting device for an artificial airway and a nebulizer, comprising a connecting tube 1 for connecting to an artificial airway, wherein the tail portion of the connecting tube 1 forms two mutually unconnected chambers, the middle portion of the connecting tube 1 is provided with a regulating mechanism 2 for regulating the nebulized gas delivery rate, and the head portion of the connecting tube 1 is provided with a nebulizer connector 11.

[0033] Embodiment 1

[0034] Reference Figures 1-5 As shown, the present application provides a connecting device for an artificial airway and a nebulizer, comprising a connecting tube 1 for connecting to an artificial airway, the tail portion of the connecting tube 1 forming two mutually unconnected chambers, the middle portion of the connecting tube 1 being connected to a regulating mechanism 2 for regulating the nebulized gas delivery rate, and the head portion of the connecting tube 1 being provided with a nebulizer connector 11.

[0035] Further, the chambers formed at the tail of the connecting pipe 1 are an intake chamber 12 and an exhaust chamber 13 respectively. A one-way intake valve 14 is arranged in the intake chamber 12, a one-way exhaust valve 15 is arranged in the exhaust chamber 13, and an air outlet hole 16 penetrating to the outside is formed on the wall of the exhaust chamber 13.

[0036] During the specific operation process, the atomized gas enters the human lungs through the intake chamber 12, and the exhaled gas enters the exhaust chamber 13 through the one-way exhaust valve 15, and then is discharged out of the body through the air outlet hole 16, so that the atomized gas and the exhaled gas have their own flow channels respectively, and the inhalation of the atomized gas will not be affected.

[0037] Furthermore, the regulation mechanism 2 includes a regulation box 21 communicated with the connecting pipe 1. Through holes 22 communicated with the connecting pipe 1 are formed on the front and rear side surfaces of the regulation box 21. A rotating plate 23 is connected in the regulation box 21 through an adjusting knob 25, and a plurality of atomizing holes 24 with different aperture sizes are arranged on the rotating plate 23.

[0038] It should be noted that the regulation box 21 is of a cylindrical structure, and the rotating plate 23 is rotationally matched and arranged inside. The atomizing holes 24 with different apertures are arranged on the rotating plate 23 in a clockwise direction from large to small. The regulation box 21 is rotationally connected with the adjusting knob 25, and the rotating plate 23 is fixedly connected with the adjusting knob 25.

[0039] During the specific process, by rotating the adjusting knob 25, the rotating plate 23 arranged in the adjusting box 21 is driven to rotate, so that the atomizing holes 24 with different aperture sizes correspond to the through holes 22 on the adjusting box 21, and then the atomized gas enters the regulation box 22 from the through hole 22 on the left side of the regulation box 21 through the connecting pipe 1, then reaches the through hole 22 on the right side of the regulation box 21 through the atomizing holes 24, and finally enters the human lungs through the connecting pipe 1, achieving the technical effect.

[0040] After atomization is completed, disconnect the connection between the connecting pipe 1 and the artificial airway, and then remove the connecting pipe 1, so that the whole device is separated from the artificial airway, and the patient is not affected when not doing atomization.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, in order to better fix the connecting pipe 1, a fixing mechanism 3 is connected with the connecting pipe 1 to realize the restraint and fixation of the connecting pipe 1.

[0043] Specifically, the fixing mechanism 3 includes a fixing plate 31. An installation hole 32 connecting the connecting pipe 1 is formed at the center of the fixing plate 31, and fixing belts 33 are connected to both sides of the fixing plate 31.

[0044] It should be noted that the connecting pipe 1 is connected to the mounting hole 32 by means of plugging.

[0045] Furthermore, the fixing piece 31 is of an arc-shaped structure, which can better fit the face or neck. The fixing belt 33 is tied to the back of the head or neck for fixation.

[0046] Preferably, the fixing piece 31 is made of a breathable soft material to avoid frictional damage to the skin.

[0047] As an example, the fixing belt 33 is provided with an adjustable buckle or Velcro or button to facilitate the connection of the fixing belt 33, thereby realizing the fixation of the connecting pipe 1.

[0048] Specific application cases:

[0049] An artificial airway generally involves inserting a catheter through the upper respiratory tract into the trachea, or directly inserting it into the trachea to form a gas passage. If there are adverse diseases in life that cause airway obstruction, it will be accompanied by difficulty in breathing. In severe cases, it is necessary to seek medical treatment in a timely manner and let professional doctors establish an artificial airway. During the operation, the trachea needs to be incised, and then a catheter is inserted into the trachea to allow the patient to breathe normally and save lives. The operation needs to be performed by experienced physicians in a regular hospital to avoid damage to local nerves. Moreover, after the artificial airway is established, it needs to be connected to a ventilator to ventilate mechanically and maintain normal respiratory function.

[0050] During the atomization treatment of an artificial airway, a catheter needs to be placed in the respiratory tract to form an artificial airway, and then an atomizer is connected to humidify the artificial airway and perform treatment, etc. Most of the existing atomizers are of the bite-type or only for connecting to a ventilator. When performing atomization treatment on patients who have been weaned from the ventilator but have not reached the extubation condition and still have an artificial airway indwelling, the atomizer cannot be well connected to the artificial airway connecting pipe, resulting in problems such as waste of liquid medicine or frequent detachment of the atomizer; and during atomization, the input rate of the atomization gas cannot be adjusted according to the needs of the patient, leading to various problems such as reduced atomization efficacy or discomfort for the patient.

[0051] Based on this, the present application provides a connecting device for an artificial airway and an atomizer. During the specific operation process, the connecting pipe 1 is inserted into the artificial airway, and the atomization connecting head 11 at the head of the connecting pipe 1 is connected to the atomizer for atomization treatment. Further, the fixing belts 33 on both sides of the fixing piece 31 are tied to the back of the head or neck for fixation.

[0052] During the atomization process, the atomizing gas enters the human lungs through the intake chamber 12, and the exhaled gas enters the outlet chamber 13 through the one-way outlet valve 15 and then is discharged out of the body through the air outlet holes 16, so that the atomizing gas and the exhaled gas have their own flow channels respectively, without affecting the inhalation of the atomizing gas.

[0053] Furthermore, by rotating the adjustment knob 25, the rotating piece 23 arranged in the adjustment box 21 is driven to rotate, so that the atomizing holes 24 with different aperture sizes correspond to the through holes 22 on the adjustment box 21. Then, the atomizing gas enters the adjustment box 22 from the through hole 22 on the left side of the connection pipe 1 through the adjustment box 21, and then reaches the through hole 22 on the right side of the adjustment box 21 through the atomizing holes 24, and finally enters the human lungs through the connection pipe 1, achieving the technical effect of regulating the atomizing gas delivery rate according to the needs of different patients.

[0054] After atomization, the connection between the connecting pipe 1 and the artificial airway can be disconnected.

[0055] In summary, although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
