Description

Technical Field

[0001] The utility model belongs to the field of tracheal tubes, and in particular relates to a breathing trainer and a tracheal tube adapted for the tracheal tube. Background Art

[0002] An endotracheal tube is a commonly used medical device in the healthcare field. Its main principle is to be inserted into the patient's trachea and / or bronchi to create a temporary artificial breathing channel for patients who cannot breathe on their own. The endotracheal tube is a temporary medical device that no longer needs to be removed from the body once the patient can breathe normally.

[0003] Before removing the tracheal tube from the patient, it is obviously necessary to first determine whether the patient can breathe normally on their own. If the patient can breathe normally, then the tracheal tube can be removed from the patient. In the prior art, to determine whether the patient can breathe normally on their own, the opening of the tracheal tube is typically directly blocked using a rubber stopper or other component. If the patient can still breathe normally with the opening of the tracheal tube blocked, then the tracheal tube can be removed from the patient. However, if the patient cannot breathe normally with the opening of the tracheal tube blocked, then the tracheal tube cannot be removed from the patient.

[0004] However, the applicant has found in practice that the above method has some shortcomings, which are mainly reflected in that if the mouth of the tracheal tube is blocked and the patient is unable to breathe independently, then the patient will obviously be in a state of suffocation, and the patient will feel severe discomfort. At the same time, there are certain safety hazards. Utility Model Content

[0005] The utility model provides a breathing trainer adapted for a tracheal tube, which aims to solve the problem in the prior art that when determining the patient's status, the patient has a risk of suffocation.

[0006] In order to achieve the above object, the utility model provides a breathing trainer adapted for a tracheal tube, comprising:

[0007] a connecting tube, the connecting tube being provided with a connecting portion, the connecting portion being used to be detachably connected to the mouth of the tracheal tube, so that the tracheal tube is in communication with the outside world through the connecting tube;

[0008] A closing component is provided on the connecting pipe and is used to completely or partially close the connecting pipe;

[0009] A gas flow detector is provided on the connecting pipe and is located at the rear end of the sealing component.

[0010] In this solution, the connecting tube can be partially sealed by providing a sealing member. Therefore, to determine if a patient has recovered, the connecting tube can be partially sealed, and then the patient can be asked to feel for signs of dyspnea, thereby determining whether the patient can breathe independently through the nasal cavity. Furthermore, since the connecting tube is partially sealed, ventilation is still possible, eliminating the risk of suffocation associated with existing technologies.

[0011] Preferably, in order to achieve a detachable connection with the tracheal tube, the connecting portion of this solution is a fitting channel, which is provided at the end of the connecting tube. The fitting channel is used to embed the end of the tracheal tube, so that the connecting portion and the tracheal tube can be detachably connected.

[0012] This solution realizes the interlocking connection by providing an interlocking channel. The interlocking connection ensures the connection between the connecting tube and the tracheal tube, and at the same time, ensures that the connecting tube and the tracheal tube can be disconnected more quickly.

[0013] Preferably, in order to ensure the sealing of the connection between the humble channel and the tracheal tube, the embedded channel of this solution is also provided with a sealing ring.

[0014] Preferably, in order to achieve a detachable connection with the tracheal tube, the present solution can also configure the connecting portion as a conical embedding head, which is arranged at the end of the connecting tube and is used to embed into the mouth of the tracheal tube, so that the connecting portion and the tracheal tube can be detachably connected.

[0015] This solution can also use the conical insert head to embed into the interior of the tracheal tube, thereby ensuring the connection between the connecting tube and the tracheal tube. At the same time, the conical insert head still uses a chimeric connection method, ensuring the connection between the connecting tube and the tracheal tube, while also ensuring that the connecting tube and the tracheal tube can be disconnected more quickly.

[0016] Preferably, in order to seal the connecting pipe, the sealing component in this solution is an electric valve, and the electric valve is electrically connected to the control module.

[0017] This solution is easy to use by setting up an electric valve and a controller, and the controller can control the sealing accuracy of the electric valve.

[0018] Preferably, in order to facilitate the user to determine the opening of the electric valve, the present solution further includes a display, which is electrically connected to the control module.

[0019] Preferably, in order to partially or completely seal the connecting pipe, the sealing component in this solution is a flow rate regulator.

[0020] or,

[0021] In order to partially or completely close the connecting pipe, the closing component is a mechanical valve.

[0022] Preferably, in order to facilitate the patient to disconnect the connecting tube from the tracheal tube in time when feeling uncomfortable, the present solution further includes a holder, which is provided on the connecting tube.

[0023] In this solution, when the patient uses the device, the patient holds the holder. Therefore, when the patient feels unwell, the patient can pull out the connecting tube through the holder, and the connecting tube is disconnected from the endotracheal tube.

[0024] The second aspect of the present invention provides a tracheal tube, comprising:

[0025] trachea;

[0026] A sealing component is provided on the trachea, and is used to completely or partially close the trachea;

[0027] A gas flow detector is provided in the gas pipe and is located at the rear end of the sealing component.

[0028] The second aspect of this solution discloses an organ conduit that can be partially closed by a closing member. The tracheal conduit can be partially closed by the tracheal conduit, and the patient can breathe through the partially closed tracheal conduit without suffocation, thus solving the shortcomings of the prior art.

[0029] Preferably, in order to ensure that the sealing component and the flow monitoring device do not interfere with the patient's normal life, the trachea described in this solution includes a connecting section and a control section, and the control section is detachably connected to the connecting section; the sealing component and the gas flow detector are both arranged in the control section.

[0030] The beneficial effects of the present invention are as follows: First, the connection tube can be partially sealed by providing a sealing member. Therefore, when it is necessary to determine whether the patient has recovered, the connection tube can be partially sealed and then the patient can be asked to feel whether dyspnea occurs, thereby determining whether the patient can breathe independently through the nasal cavity. At the same time, since the connection tube is in a partially sealed state, ventilation can still be achieved, thus solving the problem of suffocation risk in patients with the prior art.

[0031] Second, during the recovery stage, the patient connects the trainer to the endotracheal tube, and breathes through the nasal cavity and the connecting tube at the same time, and then gradually closes the connecting tube. The patient can gradually get used to getting rid of the endotracheal tube for breathing training, which is more conducive to the patient's recovery. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the objectives, technical solutions, and advantages of the embodiments more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0037] It should be noted that all actions of obtaining signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0038] In this disclosure, unless otherwise specified, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not convey order or importance.

[0039] Example 1

[0040] Basically as attached Figure 1 As shown, a breathing trainer adapted for a tracheal tube can be adapted to a conventional tracheal tube in the prior art, so that a patient can perform breathing training through the breathing trainer while wearing a tracheal tube, and determine the patient's recovery status.

[0041] The breathing trainer adapted for the endotracheal tube in the embodiment of the present disclosure specifically includes a connecting tube 1 , a sealing component 2 , a gas flow detector 3 and a holder 4 .

[0042] In the disclosed embodiment, the connecting tube 1 may be a plastic or silicone tube, through which gas can pass. The distal end of the connecting tube 1 is provided with a connecting portion 11, which is detachably connected to the mouth of a conventional endotracheal tube via the connecting portion 11, thereby maintaining communication between the endotracheal tube and the outside world through the connecting tube 1.

[0043] The connecting portion 11 in the embodiment of the present disclosure can be a chimeric channel, that is, a chimeric channel is provided at the end of the connecting tube 1, and the size of the chimeric channel is larger than the size of the mouth of the tracheal tube. The mouth of the tracheal tube can be embedded in the connecting tube 1, so that the connecting tube 1 and the tracheal tube are in a detachable connection state. In order to construct the chimeric channel, the end of the connecting tube 1 can be directly set to be larger than the diameter of the mouth of the tracheal tube, so that a chimeric channel is formed at the mouth of the connecting tube 1. Alternatively, a chimeric tube can be provided at the end of the connecting tube 1, and the chimeric tube is preferably a silicone tube, and the inside of the chimeric tube is a chimeric channel. The chimeric tube can be installed to the end of the connecting tube 1 by bonding or other methods.

[0044] At the same time, to ensure the seal between the connecting tube 1 and the interlocking channel, a sealing ring is provided inside the interlocking channel in the embodiment of the present disclosure. The sealing ring can be a rubber ring, etc. When the tracheal tube is inserted into the interlocking channel, the sealing ring deforms, thereby achieving a better seal at the connection between the tracheal tube and the connecting tube 1.

[0045] It should be noted that in the disclosed embodiment, the connecting tube 1 and the endotracheal tube are connected by providing a fitting channel. However, various methods of achieving a fitting connection exist in the prior art. For example, the connecting portion 11 can be configured as a tapered insert, which can be attached to the end of the connecting tube 1 by bonding or other means. The tapered insert is generally conical and has an internal channel for gas flow. The front end of the tapered insert can be inserted into the opening of the endotracheal tube, thereby achieving a detachable connection between the connecting tube 1 and the endotracheal tube.

[0046] In the disclosed embodiment, the sealing component 2 is a valve, which is a mechanical pipe valve. The valve can partially or completely seal the connecting pipe 1. When the valve completely seals the connecting pipe 1, no air can flow through the connecting pipe 1. When the valve partially seals the connecting pipe 1, some air can flow through the connecting pipe 1.

[0047] It is understood that while the connection tube 1 is sealed by a valve in the disclosed embodiment, it is apparent that in other embodiments, the sealing member 2 may also be a flow rate regulator. The flow rate regulator is specifically a flow rate regulator used in conventional disposable infusion sets, and the sealing state of the connection tube 1 is adjusted by the conventional flow rate regulator. The specific structure of the flow rate regulator is conventional and will not be described in detail here.

[0048] In the disclosed embodiment, a gas flow detector 3 is also mounted on the connecting tube 1. This gas flow detector 3 can be a conventional device for detecting respiratory volume, and is not described in detail in this disclosed embodiment. Specifically, the gas flow detector 3 is located at the rear end of the sealing member 2. In other words, exhaled gas passes through the sealing member 2 and is detected by the gas flow detector 3. The rear end of the sealing member 2 is the end that is connected to the outside world.

[0049] In the disclosed embodiment, the gripper 4 can be an annular handle. The gripper 4 is disposed on the connecting tube 1 and can be installed by sleeves. The gripper 4 is designed to be held by the user, allowing the user to promptly pull out the connecting tube 1 to separate it from the endotracheal tube.

[0050] Since the front end of the connecting tube 1 extends outward after the connecting tube 1 is provided, the connecting tube 1 may be blocked by clothing or a bed sheet. In the embodiment disclosed herein, the front end of the connecting tube 1 is preferably trumpet-shaped and conical. Therefore, even if the front end of the connecting tube 1 comes into contact with clothing or a bed sheet, the front end of the connecting tube 1 will not be blocked, ensuring that the patient can breathe through the connecting tube. In addition, in the embodiment disclosed herein, a connecting port 12 is preferably provided on the side of the front end of the connecting tube 1. Several connecting ports 12 are provided, and are distributed on different sides and at different heights of the front end of the connecting tube 1. In other words, even if the front end of the connecting tube 1 is blocked by clothing or a bed sheet, the connecting port 12 provided on the side of the connecting tube 1 can still ensure that the patient can breathe normally.

[0051] The following is a detailed description of a specific embodiment: To test whether a patient is breathing normally, first connect connecting tube 1 to the endotracheal tube, allowing the patient to breathe through the connecting tube 1 and the endotracheal tube. Then, sealing member 2 gradually seals connecting tube 1, reducing the amount of gas inhaled and exhaled through connecting tube 1. The patient's own sensation is then used to determine whether any discomfort is present. If the patient experiences difficulty breathing during the sealing process (for example, when 60% of connecting tube 1 is sealed), it indicates that the endotracheal tube cannot be removed for the time being. Simultaneously, the value of gas flow detector 3 in this state is recorded.

[0052] After the patient has recovered for a while, connect tube 1 is resealed to the aforementioned closed position (60% of the tube is closed). If the patient feels well and the value of gas flow detector 3 decreases (indicating that some gas is being inhaled and expelled through the nasal cavity), the patient is recovering well and connect tube 1 can be continued to be sealed until the patient feels unwell.

[0053] Repeat the above process until the patient gradually gets used to the connection tube 1 being completely closed and relies entirely on the nasal cavity for breathing, which means that the patient is ready for the endotracheal tube.

[0054] Example 2

[0055] The embodiment of the present disclosure differs from embodiment 1 in that, in embodiment 1, the connection pipe 1 is sealed by a mechanical valve. However, it is obvious that when the connection pipe 1 is sealed by a mechanical valve, it is impossible to determine the state to which the mechanical valve seals the connection pipe 1. The user can only rely on experience, which is obviously prone to errors.

[0056] To address the aforementioned issues, the present embodiment differs from Example 1 in that the sealing component 2 is an electronic valve. The electronic valve is connected to a control module, which is in turn connected to a display. The control module in the present embodiment can be a PLC control module, a single-chip microcomputer control module, an industrial computer control module, or other conventional control modules. In the present embodiment, the display, control module, and electronic valve are preferably integrated to ensure a smaller overall device size and greater ease of use.

[0057] The user can control the electronic valve through the control module to make the electronic valve accurately close the connecting pipe 1 by 20%, 40%, 60%, 80% and 100%, etc. At the same time, the display shows the state of the electronic valve closing the connecting pipe 1.

[0058] Example 3

[0059] The present disclosure provides a tracheal tube, such as Figure 2 As shown, it includes a gas pipe 5, a sealing component 2 and a gas flow detector 3.

[0060] In the embodiment of the present disclosure, the trachea 5 includes a connecting section 51 and a control section 52. The connecting section 51 is used to be inserted into the human body, and the control section 52 is used to be installed on the sealing component 2 and the gas flow detector 3. In practice, the connecting section 51 can be provided with an embedded joint 51a, and the control section 52 is also provided with a docking pipe 52a. By embedding the embedded joint 51a into the docking pipe 52a, the connecting section 51 and the control section 52 can be connected detachably. Figure 3 shown.

[0061] For example, when determining the patient's recovery status, the control section 52 is engaged with the connecting section 51. When determining the patient's recovery status, the control section 52 is separated from the connecting section 51, eliminating the problem of the sealing component 2 and the gas flow detector 3 interfering with normal use.

[0062] In the disclosed embodiment, the sealing member 2 may be a valve. The valve may be a mechanical valve. The valve can partially or completely seal the control section 52. When the valve completely seals the control section 52, no air can flow through the control section 52. When the valve partially seals the control section 52, some air can flow through the control section 52.

[0063] In the embodiment of the present disclosure, the gas flow detector 3 is installed at the rear end of the control section 52. The gas flow detector 3 is used to detect the amount of gas passing through the control section 52.

[0064] In the embodiment of the present disclosure, a gripper 4 can also be provided on the control section 52. The gripper 4 can be a handle. The handle is mounted on the control section 52. The gripper 4 is designed to be held by the user so that the user can pull out the connecting section 51 in time to separate the control section 52 from the connecting section 51.

[0065] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
