Problems solved by technology

[0003] Although the existing technology controls the time of sputum suction, the duration of sputum suction needs to be set manually. Due to individual differences in patients, the manually set sputum suction duration may be too long, and there may be no sputum in the patient's trachea but the machine While still in working condition, there is a risk of damage to the tracheal mucosa

Embodiment 1

[0028] Such as figure 1 As shown, the invention provides a sputum suction device, which works according to the following process:

[0029] 101. Turn on the power supply, and after the patient is connected to the sputum suction device, turn on the vacuum device through the control module and turn on the negative pressure;

[0030] 102. During the operation of the vacuum device, the negative pressure is continuously connected, and the signal transmission module reads the signal of whether the ultrasonic sensor collects sputum;

[0031] 103. When the signal read by the signal transmission module is "Yes", the signal transmission module sends an instruction to turn on the negative pressure, and performs operation 104a; when the signal read by the signal transmission module is "No", the signal transmission module Issue a command to close the negative pressure, execute 104b;

[0032] 104a, the instruction of turning on the negative pressure is transmitted to the control module, an...

Embodiment 2

[0036] Such as figure 2 As shown, the invention provides a sputum suction device, which works according to the following process:

[0037] 201. Turn on the power supply, and after the patient is connected to the sputum suction device, turn on the vacuum device through the control module and turn on the negative pressure;

[0038] 202, the vacuum device starts to operate, and within 0 to 5 seconds after the negative pressure is turned on, the signal transmission module sends out a command to turn on the negative pressure;

[0039] 203. The vacuum device continues to run. After the negative pressure is turned on for 5 seconds, the signal transmission module reads whether the ultrasonic wave and the color mark sensor have collected signals. When the ultrasonic wave and the color mark sensor detect sputum signals at the same time, the signal is "Yes" , otherwise the signal is "No";

[0040] 204. When the signal read by the signal transmission module is "Yes", the signal transmi...

Embodiment 3

[0045] Such as image 3 As shown, the invention provides a sputum suction device, which works according to the following process:

[0046] 301. Turn on the power supply, and after the patient is connected to the sputum suction device, turn on the vacuum device through the control module and turn on the negative pressure;

[0047] 302, the vacuum device starts to operate, and within 0 to 5 seconds after the negative pressure is turned on, the signal transmission module fixedly sends out a command to turn on the negative pressure;

[0048] 303. The vacuum device continues to run. After the negative pressure is turned on for 5 seconds, the signal transmission module reads the signal of the judgment module. When the time set by the timing module has not ended, but the sputum sensing module can still collect the sputum signal , the judging module generates a "maintain" signal; when the time set by the timing module has ended and the sputum sensing module can still collect the sput...

Abstract

The invention discloses a sputum suction device, which includes a vacuum device, a liquid storage bottle, a safety bottle, a catheter, a control module, and an automatic stop device. The automatic stop device is composed of a sputum sensing module and an information transmission module. The sputum The liquid sensing module sputum aspirator is an ultrasonic sensor or a color sensor, which can decide whether to close the negative pressure of the sputum sensing module according to the signal of the sputum sensing module. There are two ways to determine whether to turn off the negative pressure of the aspirator, so it can avoid the patient's respiratory tract damage caused by the aspirator working for too long, and is more suitable for the care of infants and the elderly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sputum suction device for protecting the respiratory tract of patients. Background technique [0002] The sputum suction device is one of the commonly used clinical instruments, and it is an important tool to prevent and treat airway obstruction of patients and rescue suffocation. The electric sputum suction device in the prior art includes a vacuum device. The control module, the safety bottle, the liquid storage bottle, and the vacuum device, the safety bottle, and the liquid storage bottle are connected through conduits. CN201420193238.6 discloses an electric sputum suction device. The timer is connected in series between the vacuum device and the power switch, the power switch is turned on, the vacuum device starts to work, and the patient's sputum enters the liquid storage bottle under the action of negative pressure. The negative pressure regulator is used to adjust the s...
