Description

Technical Field

[0001] The invention relates to the technical field of sputum adsorption, in particular to an intensive care airway sputum aspirator. Background Art

[0002] Severely ill patients are often unconscious and unresponsive. During the suction operation, the traditional suction tube is easily scratched by the front end of the tube and the inner wall of the airway when inserted. The tube mouth must fit the trachea because sputum adheres to the tracheal wall. Therefore, when the patient is unconscious, it is difficult for the doctor to judge whether the patient's airway is damaged by the patient's reaction. If the end of the tube is set to a hemispherical shape and the hole is set on the side of the tube, it is difficult to control the tube to fit above the inner wall of the airway because the tube cannot move and can only be controlled by the doctor. Summary of the invention

[0003] The object of the present invention is to provide a critical care airway suction device to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A critical care airway suction device comprises a negative pressure bottle and a suction guide tube, wherein the suction guide tube is connected to the top of the circumference of the negative pressure bottle, and the front end of the suction guide tube is rotatably connected to a sputum adsorption tube, and the sputum adsorption tube is controlled to rotate by a direction control airbag arranged on the suction guide tube;

[0006] The sputum adsorption tube consists of two parallel rotating parts and an adhesion part. The rotating part is rotatably connected to the inside of the sputum suction guide tube. The adhesion part is connected to the rotating part through a curved connection part. The axis of the adhesion part is not colinear with the axis of the rotating part. The adsorption hole is opened on the side of the circumferential surface of the adhesion part away from the sputum suction guide tube.

[0007] As a further solution of the present invention: the inner wall of the end of the suction guide tube is fixedly connected to a supporting inner tube, a telescopic airbag is arranged between the rotating part and the supporting inner tube, and the telescopic airbag is connected to the direction control airbag through an air control tube buried inside the suction guide tube.

[0008] As a further solution of the present invention: a spiral groove is formed on the inner wall of the sputum suction guide tube, a slider is fixedly connected to the outer wall of the rotating part, and the slider is slidably connected to the inside of the spiral groove.

[0009] As a further solution of the present invention: the end of the rotating part is rotatably connected to a rotating ring through a rotating rib, the rotating ring is fixedly connected to the telescopic airbag, and the rotating ring is rotatably connected to the rotating part.

[0010] As a further solution of the present invention: a deflation valve is arranged at the end of the direction control airbag, and a reset tension spring is arranged inside the telescopic airbag.

[0011] As a further solution of the present invention: the sputum suction guide tube and the rotating part are sealed by a sealing flexible layer.

[0012] As a further solution of the present invention: the front end of the adhesive portion is spherical.

[0013] As a further solution of the present invention, a critical care airway suction device comprises:

[0014] A: Connect the negative pressure bottle to the external negative pressure mechanism, send the sputum adsorption tube into the trachea through the sputum suction guide tube, press the direction control airbag to make the gas inside the direction control airbag enter the telescopic airbag through the air control tube, and the telescopic airbag pushes the rotating ring forward. The slider cooperates with the rotating ribs, and the rotating part rotates on itself, making the adhesion part revolve around the rotation part, so that the adsorption holes on the side of the adhesion part move in contact with the tracheal wall. Under the negative pressure state inside the negative pressure bottle, the sputum on the tracheal wall is sucked into the adhesion part and enters the negative pressure bottle through the sputum suction guide tube to complete the sputum suction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the suction tube is inserted into the trachea, the adhesion part deviates from the axial direction of the suction tube. At this time, when the suction tube contacts the trachea, the rotating part rotates the adhesion part upward, and the adhesion part is close to the upper part of the inner wall of the trachea, so that the sputum in the area above the inner wall of the trachea can be adsorbed. The adhesion part rotates around the curved connecting part without causing sliding damage to the inner wall. The front end of the adhesion part is spherical. As the suction tube extends farther, the end of the adhesion part will not scratch the inner wall of the trachea. When the adhesion part rotates downward, the suction tube will be lifted up. After being lifted up, the adsorption hole can adhere to the sputum on the inner wall of the trachea.

[0017] Every time the doctor inserts the suction guide tube to a standard depth, he can drive the adhesive part to rotate once, so that the adhesive part fits the inner wall of the trachea and rotates, thereby absorbing the sputum on the inner wall of the trachea. After the adhesive part rotates one circle, it continues to go deeper, thereby fully and non-destructively absorbing the sputum. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 3 :

[0024] In this embodiment, a negative pressure bottle 1 and a sputum suction guide tube 2 are included. The sputum suction guide tube 2 is connected to the top of the circumferential side of the negative pressure bottle 1. The front end of the sputum suction guide tube 2 is rotatably connected to a sputum adsorption tube 5. The sputum adsorption tube 5 is controlled to rotate by a direction control airbag 3 arranged on the sputum suction guide tube 2. The sputum adsorption tube 5 is composed of two parallel rotating parts 51 and an adhesion part 53. The rotating part 51 is rotatably connected to the inside of the sputum suction guide tube 2. The adhesion part 53 is connected to the rotating part 51 through a curved connection part 52. The axis of the adhesion part 53 is not colinear with the axis of the rotating part 51. The adsorption hole 6 is provided on the side of the circumferential surface of the adhesion part 53 away from the sputum suction guide tube 2.

[0025] In this embodiment, the top of the negative pressure bottle 1 is connected to the external negative pressure mechanism through a pipeline, and the negative pressure mechanism works to form a negative pressure environment inside the negative pressure bottle 1. When the sputum suction guide tube 2 is inserted into the trachea, the adhesion portion 53 deviates from the axial direction of the sputum suction guide tube 2. At this time, when the sputum suction guide tube 2 contacts the trachea, the rotating portion 51 rotates the adhesion portion 53 to the top, and the adhesion portion 53 can be close to the upper part of the tracheal inner wall, so that the sputum in the upper area of ​​the tracheal inner wall can be adsorbed. The adhesion portion 53 rotates around the curved connecting portion 52 as the center without causing sliding damage to the inner wall. The front end of the adhesion portion 53 is spherical. As the distance of the sputum suction guide tube 2 increases, the end of the adhesion portion 53 will not scratch the tracheal inner wall. When the adhesion portion 53 rotates to the bottom, the sputum suction guide tube 2 will be lifted up. After being lifted up, the adsorption hole 6 can adhere to the sputum on the tracheal inner wall.

[0026] In this embodiment, when the doctor inserts the sputum suction guide tube 2 into a standard depth, the doctor can drive the adhesive part 53 to rotate once, so that the adhesive part 53 is attached to the inner wall of the trachea and rotates, thereby absorbing the sputum on the inner wall of the trachea. After the adhesive part 53 rotates one circle, it continues to go deeper, thereby completely and non-destructively absorbing the sputum.

[0027] In this embodiment, the inner wall of the end of the suction guide tube 2 is fixedly connected to the supporting inner tube 21, and a telescopic airbag 7 is arranged between the rotating part 51 and the supporting inner tube 21. The telescopic airbag 7 is connected to the direction control airbag 3 through the air control tube 32 buried inside the suction guide tube 2.

[0028] In this embodiment, the rotating part 51 and the adhesive part 53 both have a certain hardness, and the hardness of the rotating part 51 and the adhesive part 53 can also be selected to be smaller than the hardness of the sputum suction guide tube 2. During control, the direction control airbag 3 is pressed to compress the gas inside the direction control airbag 3 into the inside of the telescopic airbag 7, and the telescopic airbag 7 controls the sputum adsorption tube 5 to move forward slightly. This control method can ensure cleanliness, has a simple structure, and has a low preparation cost.

[0029] In this embodiment, a spiral groove 22 is formed on the inner wall of the sputum suction guide tube 2 , and a slider 511 is fixedly connected to the outer wall of the rotating portion 51 , and the slider 511 is slidably connected inside the spiral groove 22 .

[0030] In this embodiment, the spiral groove 22 is simply opened, and the inner wall of the spiral groove 22 can reduce the sliding friction by attaching a Teflon film. At the same time, when the slider 511 is affected by the axial thrust of the suction guide tube 2, the slider 511 will spin in the spiral groove 22, thereby driving the adhesion part 53 to rotate around the rotating part 51.

[0031] In this embodiment, the end of the rotating portion 51 is rotatably connected to a rotating ring 54 via a rotating rib 512 . The rotating ring 54 is fixedly connected to the telescopic airbag 7 . The rotating ring 54 is rotatably connected to the rotating portion 51 .

[0032] In this embodiment, since the telescopic airbag 7 can only move in one direction, the telescopic airbag 7 is fixedly connected to the rotating ring 54. When the rotating ring 54 is driven forward, the rotating part 51 and the rotating ring 54 rotate to generate spin.

[0033] In this embodiment, a deflation valve 31 is provided at the end of the direction control airbag 3, and a reset tension spring 71 is provided inside the telescopic airbag 7; for the convenience of storage, the deflation valve 31 can be opened, and after the direction control airbag 3 is pressed to discharge the gas, the deflation valve 31 is closed, and at this time, the direction control airbag 3 will not cause the sputum adsorption tube 5 to rotate frequently due to accidental touch. The telescopic airbag 7 can also be provided in the form of an annular telescopic sleeve, and the telescopic airbag 7 is accommodated in the groove body of the annular telescopic sleeve, so that the telescopic airbag 7 can only move along the axial groove body when inflated, and the reset tension spring 71 can make the adhesion part 53 reset and rotate when the direction control airbag 3 is released, simplifying the control steps.

[0034] In this embodiment, the suction guide tube 2 and the rotating part 51 are sealed by a sealing flexible layer 4; the sealing part can ensure the sealing between the suction guide tube 2 and the sputum adsorption tube 5, and prevent gas from being discharged through the matching gap between the suction guide tube 2 and the rotating part 51.

[0035] In this embodiment, the front end of the adhesion portion 53 is spherical; the spherical shape can prevent the adhesion portion 53 from scratching the inner wall when pushed.

[0036] The method of using the present invention is as follows: A: connect the negative pressure bottle 1 to an external negative pressure mechanism, send the sputum adsorption tube 5 into the trachea through the sputum suction guide tube 2, and press the direction control airbag 3 to allow the internal gas of the direction control airbag 3 to enter the telescopic airbag 7 through the air control tube 32. The telescopic airbag 7 pushes the rotating ring 54 forward, and the slider 511 cooperates with the rotating rib 512, so that the rotating part 51 rotates, causing the adhesion part 53 to revolve around the rotating part 51, so that the adsorption holes 6 on the side of the adhesion part 53 move in contact with the tracheal wall. Under the state of negative pressure inside the negative pressure bottle 1, the sputum on the tracheal wall is sucked into the adhesion part 53 and enters the negative pressure bottle 1 through the sputum suction guide tube 2 to complete the sputum suction.

[0037] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
