Description

Technical Field

[0001] The present disclosure relates to the technical field of clinical respiratory medical equipment, and in particular to a negative pressure adjustable artificial sputum suction tube, a sputum suction tube adjustment system and adjustment method, and electronic equipment. Background Art

[0002] Suction tubes are widely used in clinical practice, mainly to clear sputum and secretions from the respiratory tract, which may accumulate in the mouth, trachea and bronchi, hindering normal breathing and gas exchange. Sputum removal through suction tubes can relieve airway obstruction, improve ventilation function, and reduce the risk of infection and complications. Its specific applications include:

[0003] 1. Clearing respiratory tract sputum

[0004] In airway management, the suction tube is a key tool used to ensure that the airway is open. It can be used to clear sputum in daily care, as well as to keep the patient's airway clean and open before and after surgery and during anesthesia management.

[0005] 2. Endotracheal intubation and tracheotomy care

[0006] For patients with endotracheal intubation and tracheotomy, a suction tube is a necessary tool to regularly clear sputum and secretions from the trachea. This helps maintain a patent airway and prevent complications such as ventilator-associated pneumonia.

[0007] The traditional application methods of suction tubes mainly include:

[0008] 1. Oral suction

[0009] Insert the suction tube from the mouth to the throat about 15 cm. In the absence of suction, insert the suction tube steadily and quickly while the patient inhales.

[0010] 2. Nasal suction

[0011] If oral suction is difficult, nasal suction can be used (not for patients with skull base fracture). When the patient inhales, the suction tube is smoothly and quickly inserted along the nasal passage to the throat, with a depth of 20 to 25 cm.

[0012] However, the traditional application of suction tubes still has the following application defects in clinical practice:

[0013] First, during the suction process, most people rely on experience to perform negative pressure suction. Nurses or patients rely on experience or body feeling to adjust the suction negative pressure. Therefore, there is no definite suction standard value to guide nurses or patients to perform suction in an anticipatory manner rather than blindly.

[0014] Secondly, currently using Figure 1When the traditional suction tube is used in clinical practice, the patient or nurse will insert the end of the suction tube into the patient's throat through the mouth, and generally evaluate the length of the suction tube inserted into the throat by naked eyes. However, for some users who are inexperienced or inconvenient to use, it is not convenient to control the insertion depth, so the suction tube may not be inserted deep enough or too deep, and the sputum cannot be effectively suctioned, or even inserted too deep to damage soft tissue;

[0015] In addition, the use of suction tubes is always done on-site and the background cannot keep statistics on their application records, such as the number of suction times, the negative pressure value used for each suction, etc. The background cannot monitor the patient's use of suction tubes in a timely and effective manner, and cannot effectively supervise their suction behavior, resulting in a lack of suction management.

[0079] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0080] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0081] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0082] Example 1

[0083] like Figure 1The sputum suction tube currently used in clinical practice is mainly composed of a transparent tube and a joint, which can be connected to a negative pressure system (the system sets the negative pressure value in advance). However, the negative pressure system is large in size and is generally provided by the hospital, which is inconvenient to move and carry, and is expensive.

[0084] The present invention provides a sputum suction tube with a simple structure, convenient to carry and simple and adjustable negative pressure, which can be flexibly moved and used, and is low in cost and easy to promote and use. In addition, the nurse station backstage can monitor the sputum suction information of the sputum suction patient (patient), which is convenient for monitoring.

[0085] On the one hand, the present application provides a negative pressure adjustable artificial sputum suction tube, comprising:

[0086] A negative pressure component, used for providing adjustable negative pressure;

[0087] A sputum suction tube assembly, used for suctioning sputum under the adjustable negative pressure;

[0088] The sputum suction tube assembly is mounted on the negative pressure assembly.

[0089] Combine the following Figure 2-7 The suction tube is equipped with a negative pressure component and can adjust the negative pressure according to the required suction negative pressure value, and the negative pressure value required for suction is quantitatively set according to the negative pressure scale, so that the negative pressure can be stably adjusted to avoid blind suction.

[0090] The sputum suction tube of the present invention is also provided with a sputum suction warning mark, which can judge the insertion depth according to the warning mark when the sputum suction tube is inserted into the patient's throat, so as to avoid the sputum suction tube being inserted too deeply or insufficiently, resulting in ineffective sputum suction. At the same time, the warning mark can be used to avoid deep insertion and damage to soft tissue.

[0091] By adopting the suction tube of the present invention, the negative pressure switch therein can be utilized to monitor the suction information and the suction information can be reported to the background of the nurse station. The suction time and number of suctions of the current patient and the corresponding suction negative pressure value are generated in the background, which is convenient for background monitoring of the suction patients, thereby effectively recording and supervising the suction patients and realizing the background intelligent management service of suction.

[0092] This will be described in detail below.

[0093] like Figure 2 As shown, preferably, the negative pressure component comprises:

[0094] The negative pressure cylinder 2, the tail end 11 of the sputum suction tube assembly is installed at the exhaust port 1 of the negative pressure cylinder 2, and preferably the tail end 11 of the sputum suction tube assembly is connected to the exhaust port 1 of the negative pressure cylinder 2 by magnetic attraction;

[0095] The piston 5 is sealed and fitted in the negative pressure cylinder 2, and is used to generate a sputum suction negative pressure in the negative pressure cylinder 2 when it is pulled toward a side away from the exhaust port 1;

[0096] A negative pressure scale 3 is evenly arranged on the outer surface of the negative pressure tube 2 and is used to quantitatively evaluate the suction negative pressure value in the negative pressure tube 2;

[0097] The suction negative pressure value range of the negative pressure scale 3 is -80 to -200 mHg.

[0098] The present invention combines the principle of piston syringes and sets up a negative pressure assembly similar to a syringe, which is composed of a negative pressure cylinder 2 sealed with a piston 5. The negative pressure cylinder 2 is transparent and has a negative pressure scale 3 on the outside. Each scale represents a level of suction negative pressure. Combined with the recommendation of the Chinese Nursing Association, the maximum suction negative pressure can reach -200mHg. It can actually be determined by the nurse according to the patient's condition, or the patient can adjust it by himself.

[0099] The negative pressure value can be adjusted by moving the piston 5 forward and backward along the negative pressure cylinder 2.

[0100] Preferably, the negative pressure component further comprises:

[0101] The disassembly button 6 is provided on the negative pressure cylinder 2 and is used to disassemble the negative pressure cylinder 2 into two or disassemble and connect them into a whole.

[0102] In order to facilitate cleaning, the negative pressure cylinder 2 is designed as a disassembly structure, divided into an upper and lower part, and the upper and lower parts are connected by a disassembly buckle 6. Specifically, for example, an external thread can be provided at the upper port, and a sealing thread sleeve can be provided on the lower port, and a threaded sealing connection can be performed by means of a thread, a sealing ring, or a sealing gasket.

[0103] like Figure 3 and Figure 4 As shown, preferably, the negative pressure cylinder 2 comprises an outer cylinder 200 and an inner cylinder 210, the inner cylinder 210 is fixed in the outer cylinder 200 and has a wave surface formed on its inner side;

[0104] The piston 5 includes a pull rod 9 and a piston ring 8 matched with the pull rod 9, wherein the outer side surface of the piston ring 8 matches the trough of the wave surface, that is, it is formed into a wave crest surface 10, which matches the trough surface of the wave surface;

[0105] Each trough of the wave surface corresponds to a suction negative pressure value.

[0106] Each time a negative pressure value is adjusted, the piston needs to be fixed at the corresponding scale position, so a corresponding fixing surface needs to be set in the negative pressure cylinder. The negative pressure cylinder of this invention is divided into an outer cylinder and an inner cylinder. The inner cylinder is fixed in the outer cylinder, and the inner side surface of the inner cylinder presents a wavy surface. The piston includes a pull rod and a piston ring. The outer side surface of the piston ring is formed with a wave peak surface that matches the trough of the wave surface, and the material of the wave surface and the piston ring are both flexible materials, such as silicone. During the pulling process, the piston ring can be flexibly made to enter the trough surface corresponding to the corresponding scale, so as to fix the piston ring at the corresponding scale position and set the corresponding negative pressure value.

[0107] The above-mentioned sealing conditions and sealing processes can be adjusted by the administrator at his / her discretion. For example, the seal between the piston ring and the wave surface can be achieved by setting sealing lubricating oil.

[0108] like Figure 5 As shown, preferably, the negative pressure component further includes:

[0109] The control module is arranged inside the negative pressure cylinder 2 near the end of the pull rod 9; the control module includes:

[0110] The negative pressure switch 7 is arranged at the bottom of the trough of the inner cylinder 210, and is used to activate and generate a negative pressure value signal and feed it back to the A / D converter when the piston ring 8 contacts and cooperates with the corresponding trough of the wave surface;

[0111] A / D converter (conversion between analog signal and digital signal), used to perform digital-to-analog conversion on the negative pressure value signal, generate a corresponding negative pressure value digital signal and send it to the MCU;

[0112] MCU, used to calculate the corresponding suction negative pressure value according to the negative pressure value digital signal, and send it to the wireless module in real time;

[0113] The wireless module is used to report the suction negative pressure value to the nurse station backend in real time, and the nurse station backend receives the suction negative pressure value and binds it to the identity ID of the suction patient; and monitor the working status of the suction negative pressure value, and record the suction time and suction frequency of the suction patient at the suction negative pressure value according to the working status;

[0114] Power supply, used for power supply;

[0115] The negative pressure switch 7 is electrically connected to the A / D converter;

[0116] The A / D converter, wireless module and power supply are electrically connected to the MCU respectively.

[0117] The power source can be a lithium battery or a nearby power supply. The MCU can be a STM32 series single-chip microcomputer chip. The wireless module can use Bluetooth and other communications. The specific electronic equipment signals can be selected and configured by the user.

[0118] Application system development and application of control modules:

[0119] 1. Hardware design and connection

[0120] Negative pressure switch

[0121] Selection: Choose a negative pressure switch with high sensitivity and fast response speed to ensure that it can be quickly activated when it is touched (such as when a suction tube is inserted).

[0122] Connection: Connect the output of the negative pressure switch to the input of the A / D converter.

[0123] A / D Converter

[0124] Selection: Choose a high-precision, low-noise A / D converter to ensure accurate conversion of negative pressure value signals.

[0125] Configuration: Configure the sampling rate and resolution of the A / D converter according to the signal range output by the negative pressure switch.

[0126] Connection: Connect the output (digital signal) of the A / D converter to the input of the MCU.

[0127] When the piston ring 8 contacts and cooperates with the corresponding trough of the wave surface, the negative pressure switch 7 is compressed (similar to a piezoelectric switch, etc.), and is activated at this time to generate a negative pressure value signal and feed it back to the A / D converter.

[0128] MCU

[0129] Selection: Choose an MCU with sufficient processing power and low power consumption to support real-time data processing and communication.

[0130] Programming: Write the MCU firmware to receive the digital signal from the A / D converter and perform the necessary calculations and processing.

[0131] Connection: Connect the output of the MCU (processed digital signal) to the input of the wireless module.

[0132] Wireless Module

[0133] Selection: Choose a stable, reliable, and long-distance wireless module, such as Wi-Fi, Bluetooth, or LoRa.

[0134] Configuration: Configure the communication protocol and parameters of the wireless module according to the requirements of the nurse station background.

[0135] Connection: Point the output end (wireless signal) of the wireless module to the receiving device behind the nurse station.

[0136] 2. Software Design and Implementation

[0137] MCU firmware development

[0138] Signal reception and processing: Write code to receive the digital signal from the A / D converter, and perform filtering, calibration and other processing to obtain the accurate negative pressure value.

[0139] Negative pressure value calculation: According to the processed signal, the corresponding suction negative pressure value is calculated.

[0140] Data transmission: The calculated suction negative pressure value is sent to the nurse station backend in real time through the wireless module.

[0141] Working status monitoring: monitor the working status of the negative pressure switch and record the suction time and number of suctions.

[0142] Nursing station backend software development

[0143] Data reception: Write code to receive the suction negative pressure value sent by the wireless module.

[0145] Data storage and management: Establish a database to store and manage the patient's suction records, including suction time, suction times, and negative pressure values ​​(the system can record each time it receives information). Because each negative pressure value corresponds to a scale (the corresponding capacity value can be represented on the negative pressure cylinder at the same time, for example, a certain scale represents both -80mHg and 50ml capacity, and the ratio of the negative pressure value to the capacity represented by each scale is certain, such as k), the suction volume can also be estimated = (negative pressure value / k) × suction time. Therefore, the patient's suction volume can be estimated to monitor whether it is abnormal or not.

[0146] Interface display: Develop a user interface to display the patient's suction records, making it easier for medical staff to view and analyze them.

[0147] 3. System testing and optimization

[0148] Hardware test: Test the connection and performance of each hardware component to ensure that the system can work properly.

[0149] Software testing: Test the various functions of the MCU firmware and nurse station background software to ensure the accuracy of data processing and communication.

[0151] Optimization and improvement: Based on the test results, optimize and improve the system and algorithm to improve the accuracy and reliability of the system.

[0152] 4. Deployment and Implementation

[0153] Equipment installation: Install hardware devices such as negative pressure switches, A / D converters, MCUs, and wireless modules in appropriate locations to ensure stable and reliable connections.

[0154] Software deployment: Burn the MCU firmware into the MCU and deploy the nurse station backend software to the server or computer.

[0155] Staff training: Provide medical staff with system usage training to ensure they can operate and view data proficiently.

[0156] Official launch: After completing all preparations, the system is officially launched to start real-time monitoring and recording of the patient's suctioning status.

[0157] The present invention can suction phlegm through the nose or through the mouth. There are two insertion depth warning specifications as follows.

[0158] like Figure 6 As shown, preferably, the sputum suction tube assembly comprises:

[0159] A sputum suction tube 12, with a side hole 13 at its head end;

[0160] The sputum suction warning mark 14 is arranged on the outer surface of the sputum suction tube 12, and the distance between the sputum suction warning mark 14 and the head end of the sputum suction tube 12 is:

[0161] When the sputum suction tube 12 is used for oral sputum suction, the distance between the sputum suction warning mark 14 and the head end of the sputum suction tube 12 is 14-16 cm;

[0162] When the sputum suction tube 12 is passed through the nose, the distance between the sputum suction warning mark 14 and the head end of the sputum suction tube 12 is 22-25 cm.

[0163] If the suction tube is inserted through the mouth, the suction warning mark 14 on the outer surface of the suction tube is used to judge the insertion depth to avoid excessive insertion. The suction warning mark 14 is a red mark that allows the elderly or oral insertion to determine the insertion depth to avoid excessive insertion and side effects.

[0164] like Figure 6 As shown, preferably, the sputum suction tube assembly comprises:

[0165] A sputum suction tube 12, with a side hole 13 at its head end;

[0166] The sputum suction warning convex point 15 is arranged on the outer surface of the sputum suction tube 12, and the distance between the sputum suction warning convex point 15 and the head end of the sputum suction tube 12 is:

[0167] When the sputum suction tube 12 is used for oral sputum suction, the distance between the sputum suction warning convex point 15 and the head end of the sputum suction tube 12 is 14-16 cm;

[0168] When the sputum suction tube 12 is passed through the nose, the distance between the sputum suction warning convex point 15 and the head end of the sputum suction tube 12 is 22-25 cm.

[0169] If sputum is suctioned through the nose, a protruding sputum suction warning convex point 15 is provided on the outer surface of the sputum suction tube 12, which can be touched by hand. Because the distance through the nose is long, the distance between the sputum suction warning convex point 15 and the head end of the sputum suction tube 12 is between 22-25cm. If the elderly have poor coughing ability and suction sputum by themselves, when the sputum suction tube reaches the front teeth position, the hand touches the convex point, indicating that the cough position has been reached. Therefore, it can serve as a reminder.

[0170] like Figure 7 As shown, on the other hand, the present application provides a suction tube adjustment system, comprising:

[0171] The above-mentioned negative pressure adjustable artificial sputum suction tube is used to report the sputum suction negative pressure value of the sputum suction patient to the backstage of the nurse station;

[0172] The nurse station backend is used to manage the negative pressure adjustable artificial sputum suction tube and record the binding relationship between the tube and the corresponding sputum suction patient; and receive the sputum suction negative pressure value and bind it to the identity ID of the sputum suction patient; and monitor the working state of the sputum suction negative pressure value, and record the sputum suction time and number of sputum suction times of the sputum suction patient at the sputum suction negative pressure value according to the working state;

[0173] The negative pressure adjustable artificial sputum suction tube is connected to the back-end communication of the nurse station through its wireless module.

[0174] The present invention sets a circular control carrier in the negative pressure cylinder of the suction tube, which integrates various control system facilities, and can report the corresponding negative pressure value information to the background when suctioning. After the module is activated, it communicates with the background, which identifies its device number and binds the patient information, and can record the suction negative pressure value. Every time the piston moves, the negative pressure signal changes once. By recording the state change information of the signal, the corresponding negative pressure value, the number of suction times, the suction time recorded by the system, and the evaluation amount are recorded.

[0175] Therefore, this application can realize background sputum suction monitoring.
