Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to an intelligent airway management device for intensive care. Background Technology

[0002] In the clinical practice of intensive care, airway management of patients has always been a critical link in their life safety and recovery process. Because critically ill patients often have impaired consciousness, weakened or absent cough reflex, respiratory secretions are difficult to expel on their own, which can easily lead to serious complications such as airway obstruction and lung infection. Therefore, efficient and safe sputum suction and sputum monitoring methods are particularly important.

[0003] Traditional devices often use a single suctioning method. After suctioning, patients secrete sputum again, requiring frequent suctioning, which increases the workload of medical staff.

[0004] In terms of sputum monitoring, traditional devices lack intuitive and effective monitoring methods. Medical staff cannot understand important information such as the amount, color, and characteristics of the patient's sputum in real time, making it difficult to adjust the treatment plan in a timely manner based on changes in sputum. To address these issues, we propose an intelligent airway management device for intensive care. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent airway management device for intensive care, in order to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent airway management device for intensive care, comprising an endotracheal tube, an annular airbag fixedly provided on the bottom outer wall of the endotracheal tube, an air inlet tube connected to the inner wall of the annular airbag passing through the side wall of the endotracheal tube, a hollow suction ring fixedly provided on the bottom inner wall of the endotracheal tube, a first suction hole evenly distributed on the outer wall of the hollow suction ring, a second suction hole evenly distributed on the bottom side wall of the endotracheal tube, the second suction hole communicating with the interior of the hollow suction ring through the first suction hole, a suction conduit connected to the top outer wall of the hollow suction ring, and a transparent negative pressure cylinder connected to the other end of the suction conduit passing through the top outer wall of the endotracheal tube.

[0009] Preferably, the top outer wall of the annular airbag and the bottom outer wall of the hollow liquid-absorbing ring are located on the same horizontal line.

[0010] Preferably, the top side of the transparent negative pressure cylinder is connected to an air extraction pipe through an opening, and an air extraction pipe connector is installed at one end of the top of the air extraction pipe.

[0011] Preferably, the endotracheal tube includes an oral occlusal ball, the outer wall of which has a through sliding opening, the inner wall of which is slidably connected to the outer wall of the endotracheal tube, and the oral occlusal ball is made of elastic silicone material.

[0012] Preferably, one end of the endotracheal tube is connected to an air guide tube connector through an opening, and the air guide tube connector is connected to a corrugated telescopic tube.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The hollow suction ring and the second suction hole distributed circumferentially at the bottom of the endotracheal tube form an annular suction area, which, together with the vertically connected first suction hole, creates a three-dimensional secretion removal channel, allowing for continuous suctioning of the patient's airway.

[0015] A visual negative pressure system consisting of a transparent negative pressure cylinder and a suction tube allows for real-time monitoring of the patient's sputum secretion volume and condition, facilitating the detection of the patient's respiratory tract. Attached Figure Description

[0026] Example 1

[0027] Refer to the instruction manual appendix Figure 1-5An intelligent airway management device for intensive care includes an endotracheal tube 1. An annular airbag 2 is fixedly mounted on the bottom outer wall of the annular airbag 1 and communicates with the side wall of the endotracheal tube 1 through an inflation tube 3. The other end of the inflation tube 3 passes through the top outer wall of the endotracheal tube 1 and connects to an inflation tube connector 4, which facilitates the use of an external syringe for airbag inflation. The top outer wall of the annular airbag 2 and the bottom outer wall of the hollow suction ring 8 are on the same horizontal plane, so that the airway sealing and suction functions work together. The inner wall of the hollow suction ring 8 forms a communication structure with the second suction holes 10 distributed circumferentially along the bottom side wall of the endotracheal tube 1 through the equidistantly distributed first suction holes 9, so that secretions can enter the suction ring through the dual channels. The top of the suction ring is connected to a transparent negative pressure cylinder 12 through a suction conduit 11. The top of the negative pressure cylinder is provided with an air extraction tube 13 and an air extraction tube connector 14, which can be connected to a negative pressure suction device to collect secretions.

[0028] Example 2

[0029] Based on Embodiment 1, a sliding tube 5 is slidably connected to the outer wall of the air injection tube 3. The side wall of the sliding tube 5 is connected to a stud 7 via a threaded tube 6. Rotating the stud 7 can push the sliding tube 5 to move axially along the air injection tube 3, thereby changing the effective inflation length of the annular airbag 2. When it is necessary to reduce the airbag pressure, the stud 7 is screwed outward to move the sliding tube 5 downward, reducing the effective air passage of the air injection tube 3; conversely, screwing the stud 7 inward increases the inflation length, achieving graded pressure regulation, avoiding over-inflation that could damage the airway mucosa, and maintaining a sealing effect.

[0030] Example 3

[0031] Based on Embodiment 1, an oral occlusal ball 15 made of elastic silicone is provided in the middle section of the endotracheal tube 1. Its sliding port slides and engages with the outer wall of the endotracheal tube 1. The oral occlusal ball 15 can adaptively move with the patient's biting action, disperse biting force and protect the endotracheal tube 1.

[0032] Example 4

[0033] Based on Embodiment 1, the use flexibility is improved by connecting the top of the endotracheal tube 1 to the corrugated telescopic tube 17 via the airway connector 16. The corrugated telescopic tube 17 can automatically adjust its length and curvature according to the patient's position, avoiding airway damage caused by tube traction. When a ventilator needs to be connected, the corrugated tube 17 can maintain a natural curved state to reduce airflow resistance.

[0034] Example 5

[0035] Based on Example 1, a transparent negative pressure cylinder 12 is used to achieve visualized secretion management. The negative pressure cylinder is made of transparent material to facilitate observation of the amount and characteristics of secretions. During the aspiration process, the synergistic effect of the first aspiration hole 9 and the second aspiration hole 10 forms an annular aspiration area, effectively clearing secretions around the airway.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figure 1-5 Connect the corrugated telescopic tube 17 to the ventilator or oxygen supply equipment via the airway connector 16. Then, insert the endotracheal tube 1 through the mouth or into the patient's airway to the appropriate depth. Inflate the annular cuff 2 with a syringe connected to the airway connector 4. Adjust the position of the sliding tube 5 by rotating the stud 7 to control the cuff pressure and avoid over-inflation that could damage the airway. Subsequently, connect the suction tube connector 14 to the negative pressure suction device. Turn on the negative pressure to generate suction in the transparent negative pressure cylinder 12. Suction secretions around the airway are removed through the first suction hole 9 and the second suction hole 10 of the hollow suction ring 8. The amount of liquid in the negative pressure cylinder can be observed in real time and replaced promptly. If the patient needs oral care, the oral occlusal ball 15 can be slid axially to expose the operating area. After completion, reset it to continue protecting the endotracheal tube 1.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
