Problems solved by technology

That is, it is not possible to deal with sputum in the trachea while artificial respiration continues
[0013] (3) If the diaphragm type sputum aspirator 100 is used, even if the sputum collection bottle 109 is put into disinfectant, the sputum discharge tube 111 connected to the suction tube cannot be immersed in the disinfectant, so that the Sterilization in case of exposure to the interior space of the collection bottle 109
However, the suction force of the tube pump is weak, and the liquid flow rate per unit time is also small

Embodiment 1

[0075]In Fig. 1, 10 is an artificial respiration system using the suction device for sputum in the trachea according to Embodiment 1 of the present invention. This artificial respiration system 10 has: the artificial ventilator 12 that is connected with the breathing tube 11 of air supply and exhaust; The tracheal intubation tube 14 that communicates with the breathing tube 11 and is inserted in the patient's trachea 13; 15 communicates with a sputum suction device (suction device for sputum in the trachea) 16, the suction tube 15 communicates with the breathing tube 11 and sucks out the sputum trapped in the trachea 13; two sputum collection bottles 17A, 17B; paired with the suction tube 15 The control unit 18 that controls the sputum suction pressure generated by the sputum suction device 16 and the opening and closing of the artificial respirator 12 corresponding to the internal pressure by a sequencer.

[0076] The artificial respirator 12 is a device that ensures breathin...

Embodiment 2

[0106] Next, the suction device for sputum in the trachea according to Embodiment 2 of the present invention will be described with reference to FIG. 5 . As shown in FIG. 5 , the artificial respiration system 10A employing the device for aspirating endotracheal sputum according to Embodiment 2 of the present invention does not respond to changes in the internal pressure of the suction tube 15 based on the detection signal from the pressure sensor 31 as in Embodiment 1. Sputum suction is controlled, and only the tube pump 16A is used to continuously perform sputum suction at a low speed, fixed amount (100 cc / sec), and high pressure.

[0107] Therefore, in Example 2, the auxiliary pump 16B, the sputum collection bottle 17B, the control unit 18 , the first branch pipe 30 , the second branch pipe 32 , the safety valve 33 and the negative pressure pipe 34 are omitted. In this way, although the suction control cannot be performed by the pressure sensor 31, the number of parts of the...

Embodiment 3

[0110] Next, the device for suctioning sputum in the trachea according to Embodiment 3 of the present invention will be described with reference to FIG. 6 .

[0111] As shown in FIG. 6 , the artificial respiration system 10B employing the suction device for sputum in the trachea according to Embodiment 3 of the present invention is based on the detection signal from the pressure sensor 31 in accordance with the internal pressure of the suction tube 15 in Embodiment 2. The embodiment in which the output of the tube pump 16A is controlled is varied.

[0112] Specifically, when the suction pressure of sputum is high, this is detected by the pressure sensor 31, and the control unit 18 increases the output of the tube pump 16A based on the detection signal. On the other hand, when the suction pressure of sputum is low, this is detected by the pressure sensor 31, and the control unit 18 reduces the output of the tube pump 16A based on the detection signal.

[0113] Therefore, while...

Abstract

An intra-tracheal sputum aspirating apparatus arranged so that air feeding to and air evacuation from trachea (13) by means of artificial respirator (21) are carried out through tracheal cannula (14) and so that in the event of sputum clogging, tube pump (16A) is operated to thereby attain discharge of sputum through suction tube (15) to the outside of the body by means of a negative pressure produced thereby. By virtue of the employment of the tube pump (16A) as sputum aspirator (16), the intra-airway pressure by the artificial respirator (12) would have substantially no fluctuation even when a positive pressure is applied to the lungs. Consequently, sputum disposal can be accomplished while maintaining artificial respiration, so that there can be prevented any secondary infection by infectious agents discharged from sputum collection bottle (17) into the air.

Description

technical field [0001] The present invention relates to a suction device for sputum in the trachea, in particular to an automatic suction technology for sputum in the trachea through a hole formed in the middle of the trachea through tracheotomy. Background technique [0002] In order to ensure the breathing of patients, the technology of artificial respiration by artificial ventilator has been developed. This is a technique in which an endotracheal tube is inserted into the cut trachea, and the breathing tube extending from the artificial respirator is connected to the endotracheal tube through an adapter to perform artificial respiration. During artificial respiration, phlegm trapped in the windpipe can block the airway. Therefore, how to deal with sputum is a problem that needs to be solved. [0003] As a general example of a method for treating sputum, the following method is known. First, a medical worker removes the adapter from the endotracheal tube, and then insert...
