Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to a novel intelligent sputum suction and oxygen supply device. Background Art

[0002] Suctioning is a method of using negative pressure to suck out respiratory secretions through the mouth, nose, or artificial airway using a catheter to keep the airway open. When patients have excessive sputum due to various organic diseases, they need to use a suction device. The purpose of suctioning is to suck out respiratory secretions or aspirated vomit to keep the airway open to prevent sputum from blocking the airway and causing breathing difficulties or even suffocation. During suctioning, oxygen interruption can lead to hypoxia or hypoxemia, so oxygen is needed during suctioning. In existing actual medical treatment processes, ventilators and suction machines must be used in conjunction with suction machines to achieve suction and ventilators to provide oxygen to patients.

[0003] In the actual medical treatment process, the ventilator and the suction machine must be used together. It is acceptable when there are many medical staff in the hospital, but when performing external medical support tasks, due to the number of medical staff, a single medical staff may be required to operate them. The two devices are cumbersome to use together and require medical staff to operate them separately, which wastes medical resources and increases the personnel burden during support tasks. The cumbersome operation will delay the treatment time, which in turn affects the patient's treatment. Summary of the invention

[0028] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8In some embodiments, the oxygen supply pipe 203 includes a humidification barrel 109, a No. 1 connecting pipe 110 and a No. 2 connecting pipe 111. The humidification barrel 109 is arranged inside the shell 100, and the humidification barrel 109 extends to the inside of the oxygen supply chamber 102. One end of the No. 1 connecting pipe 110 and the No. 2 connecting pipe 111 are both connected to the inside of the humidification barrel 109, and the No. 1 connecting pipe 110 is located in the humidification barrel 109 at a height lower than the No. 2 connecting pipe 111 is located in the humidification barrel 109. The other end of the No. 1 connecting pipe 110 is connected to the oxygen supply tank 103, and the other end of the No. 2 connecting pipe 111 is connected to the input end of the oxygen supply pump 107. A sleeve 112 is provided on the surface of the humidification barrel 109, and a heating element 113 is provided inside the sleeve 112. A temperature sensor 114 is provided inside the humidification barrel 109. The hot element 113 and the temperature sensor 114 are both electrically connected to the controller 108. A liquid level sensor 115 is arranged on the top of the sleeve 112. The humidification barrel 109 is made of transparent material. The liquid level sensor 115 is used to monitor the liquid level in the humidification barrel 109. The liquid level sensor 115 is electrically connected to the controller 108. A gas flow rate sensor 119 is arranged inside the No. 2 connecting pipe 111. The gas flow rate sensor 119 is used to monitor the gas flow rate in the No. 2 oxygen supply pipe 203. The gas flow rate sensor 119 is electrically connected to the controller 108. A waterproof and breathable membrane 117 is arranged inside the No. 2 connecting pipe 111 near and located in the humidification barrel 109. A plug 127 is detachably connected to the top of the humidification barrel 109. A prompter 120 is arranged on the front of the shell 100, and the prompter 120 is electrically connected to the controller 108.

[0029] In this embodiment, oxygen flows through the oxygen tank in sequence through the No. 1 connecting pipe 110, the humidification barrel 109, the No. 2 connecting pipe 111, the oxygen supply pipe 203, the circulation cavity 202 and the oxygen supply hole 204, thereby realizing the oxygen supply operation. In this process, the oxygen will realize the oxygen humidification function through the humidification liquid stored in the humidification barrel 109, and the humidification liquid is heated by the heating element 113 to ensure that the oxygen supplied to the patient is of suitable humidity and temperature. At the same time, the humidification liquid temperature can be monitored by the temperature sensor 114 and adjusted according to the actual situation, thereby realizing targeted adjustment for different patients; wherein the humidification barrel 109 is monitored by the liquid sensor The liquid level in the humidifier 109 is displayed. When the liquid level is lower than the set threshold, the prompter 120 responds, so that the medical staff can remove the plug 127 and then add the humidifying liquid to the humidification barrel 109. The prompter 120 can use a display screen, sound, light or a combination of two or even three of them to prompt the medical staff; the gas flow rate sensor 119 monitors the gas flow rate during oxygen supply. Since different patients have different gas flow rates due to different symptoms, different gears of the oxygen supply pump 107 are selected or an adjustable flow rate valve is set on the No. 2 connecting pipe 111. The combination of the two can adapt to the usage needs of different patients.

[0030] See also Figure 1 and Figure 8 In some embodiments, a gravity sensor 116 is disposed inside the housing 100 . The number of the gravity sensors 116 is two. One of the gravity sensors 116 is used to monitor the gravity of the oxygen supply tank 103 , and one of the gravity sensors 116 is used to monitor the gravity of the sputum storage tank 104 . The gravity sensor 116 is electrically connected to the controller 108 .

[0031] In this embodiment, the gravity sensor 116 is used to monitor the gravity changes of the oxygen supply tank 103 and the sputum storage tank 104 respectively, so as to know the remaining oxygen in the oxygen supply tank 103 and the amount of sputum stored in the sputum storage tank 104. At the same time, by monitoring the weight change of the sputum storage tank 104, the change of the sputum volume during a single operation is known, and the medical staff is informed through the prompter 120 to provide data support for the medical operation of the medical staff. At the same time, when the gravity sensor 116 monitors that the gravity of the oxygen supply tank 103 is lower than the set threshold value or the gravity of the sputum storage tank 104 is higher than the set threshold value, the medical staff is prompted through the prompter 120. It is shown that a negative pressure sensor 121 is arranged in the suction tube 200 105 to monitor the negative pressure effect of the suction pump 106. If the negative pressure is too low, the purpose of suctioning sputum and clearing obstruction cannot be achieved, while if the negative pressure is too high, it will stimulate airway spasm and cause airway damage. In order to adapt to the needs of different patients, the suction pump 106 adopts a suction pump 106 with different gears to ensure that the negative pressure is appropriate. During a single suction operation, the gravity sensor 116 is used to monitor the weight change of the sputum storage tank 104, and then the sputum volume during a single operation is known. The medical staff determines whether the sputum volume is appropriate and adjusts the gear of the suction pump 106 as needed.

[0032] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the suction tube 200 and the outside of the sleeve 201 adopt a bellows structure, the oxygen supply tube 203 adopts a bellows structure, the oxygen supply tube 203, the suction tube 200 and the sleeve 201 are all made of elastic material, and a clamping ring 118 is provided on the surface of the shell 100. The clamping ring 118 is made of a deformable material and is used to fix the oxygen supply tube 203, the suction tube 200 and the sleeve 201.

[0033] In this embodiment, since the oxygen supply tube 203, the suction tube 200 and the sleeve 201 are all made of elastic material, and part of the oxygen supply tube 203 and the suction tube 200 adopt a bellows structure, the stretching operation of the oxygen supply tube 203 and the suction tube 200 is realized, which is helpful for the operation of medical staff, and the clamping ring 118 can fix the oxygen supply tube 203, the suction tube 200 and the sleeve 201 by clamping, thereby reducing the impact of the oxygen supply tube 203, the suction tube 200 and the sleeve 201 on other medical operations during the operation of medical staff.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 In some embodiments, a timer 122, a battery 125, a counterweight 123 and a level sensor 124 are disposed inside the shell 100. The timer 122 and the level sensor 124 are both electrically connected to the controller 108. A charging port 126 is opened on the front of the shell 100.

[0035] In this embodiment, the timer 122 is set to monitor the duration of a single suction to avoid adverse effects caused by a single suction time that is too long or too short. A suction time that is too long is likely to affect the patient's lungs, while a suction time that is too short cannot effectively attract sputum. Therefore, the suction time generally should not exceed 15 seconds, and there is no need for medical staff to monitor the suction time, thereby relieving the mental stress of medical staff during operation. In external medical support tasks, according to the actual operating environment, the horizontal sensor 124 can be used to know whether the device is in a horizontal state, and at the same time, the horizontal sensor 124 can be used to know whether the device is in a horizontal state. The setting of the counterweight 123 makes the center of gravity of the device tend to the bottom, thereby increasing the probability of tipping over due to accidental touch when the device is placed in a relatively horizontal position; the battery 125 can power the oxygen supply pump 107, the suction pump 106, the controller 108, the gravity sensor 116, the temperature sensor 114, the liquid level sensor 115, the heating element 113, the gas flow rate sensor 119, the prompter 120, the level sensor 124, the negative pressure sensor 121 and the timer 122, and the charging port 126 can charge the battery 125.

[0037] In this embodiment, the controller 108 transmits the working conditions of the oxygen supply pump 107, the suction pump 106, the gravity sensor 116, the temperature sensor 114, the liquid level sensor 115, the heating element 113, the gas flow rate sensor 119, the prompter 120, the level sensor 124, the negative pressure sensor 121 and the timer 122 to the wireless communicator, and displays them on the display, thereby realizing remote monitoring. At the same time, the working conditions of the relevant structures of the device are recorded through the memory, so that medical staff can retrieve the working conditions of the relevant structures through the memory to understand the patient's condition at a later stage. The terminal can be a mobile phone, a tablet, a computer, etc., and the communication connection adopts 4G, 5G, WIFI, a local area network, Bluetooth, etc.

[0038] It should be noted that in the present disclosure, the specific models and specifications of the battery 125, oxygen supply pump 107, suction pump 106, controller 108, gravity sensor 116, temperature sensor 114, liquid level sensor 115, heater 113, gas flow rate sensor 119, prompter 120, level sensor 124, negative pressure sensor 121, timer 122, wireless communicator and display need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail; its power supply and principle are clear to those skilled in the art, and will not be described in detail here; the connection and installation of its various parts and the signal transmission principle belong to the well-known technology in the field.

[0039] Specifically, the working principle of a new intelligent sputum suction and oxygen supply device provided in this application is: The sputum storage tank 104 and the oxygen supply tank 103 are placed in the sputum suction chamber 101 and the oxygen supply chamber 102 respectively in advance, and are connected to the sputum suction pump 106 and the oxygen supply pump 107 through the sputum storage pipe fitting and the oxygen supply pipe 203 respectively. During the external medical support mission, the housing 100 is placed on a set plane, and the horizontal sensor 124 is used to know whether the housing 100 is in a horizontal state, and the center of gravity of the device is inclined to the bottom by means of the setting of the counterweight block 123, so as to increase the probability of rollover due to accidental touch when the device is placed in a relatively horizontal position; When in use, take out the suction oxygen supply tube 203, connect the oxygen supply tube 203 and the suction tube 200 to the oxygen supply pump 107 and the suction pump 106 respectively, and insert the suction tube 200 sleeve 201 into a suitable position, and start the oxygen supply pump 107 and the suction pump 106 as needed; During oxygen supply, the oxygen in the oxygen supply tank 103 is supplied to the patient through the oxygen tank through the No. 1 connecting pipe 110, the humidification barrel 109, the No. 2 connecting pipe 111, the oxygen supply pipe 203, the circulation cavity 202 and the oxygen supply hole 204 in sequence under the action of the oxygen supply pump 107. In this process, the oxygen will be humidified by the humidification liquid stored in the humidification barrel 109. At the same time, the humidification liquid is heated by the heating element 113 to ensure that the oxygen supplied to the patient is of suitable humidity and temperature. At the same time, the temperature of the humidification liquid can be monitored by the temperature sensor 114 and adjusted according to the actual situation, thereby achieving targeted adjustments for different patients. During sputum suction, the sputum flows through the sputum suction tube 200 and the sputum suction tube 200 piece 105 to the sputum storage tank 104 in sequence under the action of the sputum suction pump 106. The duration of a single sputum suction is monitored by the timer 122. At the same time, the weight change of the sputum storage tank 104 is monitored by the gravity sensor 116. The change in the sputum volume during a single operation is learned, and the medical staff is informed through the prompter 120. The medical staff determines whether the sputum volume is appropriate, adjusts the gear position of the sputum suction pump 106 as needed, and monitors the adjusted negative pressure through the negative pressure sensor 121. The controller 108 transmits the working conditions of the oxygen supply pump 107, the suction pump 106, the gravity sensor 116, the temperature sensor 114, the liquid level sensor 115, the heater 113, the gas flow rate sensor 119, the prompter 120, the level sensor 124, the negative pressure sensor 121 and the timer 122 to the wireless communicator, and displays them on the display, thereby realizing remote monitoring. At the same time, the working conditions of the relevant structures of the device are recorded through the memory through the memory, so that medical staff can retrieve the working conditions of the relevant structures through the memory to understand the patient's condition at a later stage.
