Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning tool technical field, specifically, relate to a kind of electric tracheal cannula brush. BACKGROUND

[0002] Tracheal cannula is used for tracheotomy patient postoperative as respiratory tract, for example, the patient of recovery period after laryngeal cancer surgery often needs to maintain normal respiratory function by tracheal cannula, tracheal cannula is communicated with human respiratory tract, and it is easy to attach a large amount of secretion, such as pus, sputum etc., cause low blood oxygen or cause tracheal dryness infection and other complications, therefore, tracheal cannula is cleaned and disinfected regularly, to prevent bacteria breeding, while preventing secretion from blocking respiratory tract, ensure that respiratory tract is unobstructed.

[0003] The Chinese invention patent with publication number CN209680687U discloses a tracheal cannula cleaning machine, which comprises an outer cleaning tank and an inner cleaning tank arranged in the outer cleaning tank, a containing cavity is arranged between the outer cleaning tank and the inner cleaning tank, and a stirring mechanism, an ultrasonic transducer device and an electric heating body are further included. The tracheal cannula cleaning machine performs disinfection treatment by boiling cleaning liquid through the electric heating body; the ultrasonic transducer generates vibration signals in the cleaning liquid to strip the dirt on the surface of the tracheal cannula, so as to realize cleaning.

[0004] However, since the wavelength of ultrasonic wave (between 0.017m and 17m) is greater than the maximum inner diameter (0.015m) of the tracheal cannula, the ultrasonic vibration signal is difficult to act on the inside of the tracheal cannula, and the patient's sputum and sputum on the inner wall of the tracheal cannula are viscous, so it is difficult to effectively clean the inside of the tracheal cannula.

[0016] The utility model will be described in detail below with reference to the exemplary embodiments in the drawings. It should be understood that the utility model can be realized in various different forms, and should not be understood as being limited to the embodiments described herein. These embodiments are provided to make the disclosure of the utility model more complete, and to fully convey the concept of the utility model to those skilled in the art.

[0018] The endotracheal tube cleaning machine in the prior art is difficult to effectively clean the inside of the endotracheal tube. After careful analysis, the inventors found that the main reason for the above technical problems is that the wavelength of the ultrasonic wave (between 0.017m and 17m) is greater than the maximum inner diameter of the endotracheal tube (0.015m), so it is difficult for the endotracheal tube cleaning machine to act on the inside of the endotracheal tube, and the patient's sputum and sputum on the inner wall of the endotracheal tube are viscous, making it difficult to effectively clean the inside of the endotracheal tube. Based on the above analysis, the inventors designed an electric endotracheal tube brush to effectively clean the inside of the endotracheal tube. The electric endotracheal tube brush of the present application is used in combination with the existing endotracheal tube cleaning machine to effectively clean the inside and outside of the endotracheal tube.

[0019] As shown in Figure 1 The electric endotracheal tube brush of the present embodiment includes a cleaning brush assembly 1, a handle 2, and a motor 3 for driving the cleaning brush assembly 1 to rotate. The motor 3 is installed on the handle 2 and connected to the cleaning brush assembly 1. The cleaning brush assembly 1 includes a brush rod 11 and a brush head mechanism 12 arranged on the brush rod 11. The brush rod 11 is flexible and is used to extend into the endotracheal tube. The flexible bristles 15 are made of medical-grade silicone.

[0020] The brush head mechanism 12 is in the shape of a rhombus, and its diameter is adjustable to adapt to endotracheal tubes of different sizes. The brush head mechanism 12 comprises a hard rod 13, a four-bar linkage mechanism 14 and a plurality of flexible bristles 15 arranged on the four-bar linkage mechanism 14, and the four-bar linkage mechanism 14 is slidably mounted on the hard rod 13. The four-bar linkage mechanism 14 is composed of two upper rods 16 and two lower rods 17 which are hingedly connected end to end, and the four hinged points are respectively a first hinged point, a second hinged point, a third hinged point and a fourth hinged point. The first hinged point is provided with a sliding sleeve 18 which is slidably sleeved on the hard rod 13, and the third hinged point is fixedly mounted on the brush rod 11. The four-bar linkage mechanism 14 is a planar linkage structure composed of four rods which are hingedly connected to each other. Sliding the sliding sleeve 18 can expand the distance between the first hinged point and the third hinged point, and thus reduce the diameter of the brush head mechanism 12. Sliding the sliding sleeve 18 can reduce the distance between the first hinged point and the third hinged point, and thus increase the diameter of the brush head mechanism 12. By sliding the sliding sleeve 18, the brush head mechanism 12 can be expanded outwardly or contracted inwardly to adjust the expanded diameter of the brush head mechanism 12, so as to adjust the size of the bristles according to the tube diameter of the endotracheal tube, thereby effectively cleaning the secretions and small sundries attached to the inner wall of the endotracheal tube.

[0021] The hard rod 13 is a screw rod, one end of which is rotatably mounted on the brush rod 11, and the other end is provided with a knob 4. The sliding sleeve 18 is sleeved on the screw rod and is threadedly connected with the screw rod. A nut 5 is sleeved on the screw rod, and after the nut 5 is rotated, the nut 5 is abutted against the end face of the brush rod 11. The screw rod is rotated by the knob 4, so that the sliding sleeve 18 slides on the screw rod. When the diameter of the brush head mechanism 12 does not need to be adjusted, the nut 5 is abutted against the end face of the brush rod 11, and the frictional force between the nut 5 and the end face of the brush rod 11 is used to limit the rotation of the hard rod 13. Since one end of the four-bar linkage mechanism 14 is fixedly connected with the brush rod 11 and the other end is connected with the sliding sleeve 18, when the screw rod is rotated, the sliding sleeve 18 is not easy to rotate with the screw rod due to the limitation of the four-bar linkage mechanism 14.

[0022] The use of the embodiment is described as follows:

[0023] In use, first, according to the actual size of the endotracheal tube, the screw rod is rotated to adjust the bristles on the brush head mechanism 12 to the appropriate size of the endotracheal tube, and then the nut 5 is abutted against the end face of the brush rod 11. Then, the user holds the handle 2 and places the brush head mechanism 12 into the endotracheal tube. Finally, the motor 3 is started, and the brush head mechanism 12 rotates on the inner wall of the endotracheal tube to clean the patient's sputum and sputum on the inner wall of the endotracheal tube, so that the patient's sputum and sputum are separated from the inner wall of the endotracheal tube.

[0024] All the above embodiments are exemplary but not restrictive, and various modifications or variations of the above described specific embodiments made by those skilled in the art under the concept of the present application shall be within the protection scope of the present application.
