Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology and relates to artificial airway cover. Background Technology
[0002] An artificial airway is a gas passage established by inserting a tube directly into the trachea or through the upper respiratory tract into the trachea, providing conditions for effective airway drainage, patency, and mechanical ventilation. Currently, the most commonly used artificial airways are endotracheal intubation and tracheostomy tubes. Artificial airways are necessary for patients with upper airway obstruction, airway secretion retention, and those requiring mechanical ventilation.
[0003] Weaning from mechanical ventilation, also known as ventilator detachment, refers to the process by which the level of support provided by mechanical ventilation to a patient gradually decreases, the patient's spontaneous breathing gradually increases, until the patient is no longer assisted by mechanical ventilation and can breathe completely independently. The main indications include control of underlying diseases, normal physiological indicators, hemodynamic stability, and improved respiratory function.
[0004] When patients with artificial airways are weaned off ventilators, the airflow can travel through the nose / mouth (restoring the upper airway) or still partially through the artificial airway. However, after weaning, the leakage of the artificial airway is a continuous exposure without the use of a voice valve. This is not only unhygienic but also makes it easy for foreign objects to fall into the airway, increasing the risk. Therefore, an artificial airway cover is needed to solve the above problems. Utility Model Content
[0005] To address the aforementioned problems, this invention proposes an artificial airway cover, which effectively solves the issues in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The following is in conjunction with the appendix Figures 1 to 3 The specific embodiments of this utility model will be described in further detail.
[0023] Depend on Figures 1 to 3 As shown, this utility model includes a first arc-shaped plate 1 and a second arc-shaped plate 2. In order to facilitate medical staff to cover the artificial airway in the offline state, the front sides of the first arc-shaped plate 1 and the second arc-shaped plate 2 are rotatably connected. A rotatable cover plate 3 is provided on the upper side of the first arc-shaped plate 1 and the second arc-shaped plate 2. A breathing gap for ventilation is provided between the first arc-shaped plate 1 and the second arc-shaped plate 2. A first limiting plate 4 is provided on the lower side of each cover plate 3. A humidification mechanism 5 is provided on the lower exterior of each cover plate 3.
[0024] A second arc-shaped surface 20 is provided on the lower side of the first limiting plate 4, and a third arc-shaped surface 21 is provided in the middle of each of the cover plates 3.
[0025] It should be noted that both the first arc plate 1 and the second arc plate 2 are made of elastic plastic material and have a certain degree of elasticity. They can produce a certain elastic deformation after being subjected to force. When not under force, the first arc plate 1 and the second arc plate 2 are elliptical in shape as a whole, which can be adapted to artificial airway ports of different diameters, making it convenient for medical staff to use.
[0026] In addition, two rubber strips are fixedly connected to the inner sidewalls of the first arc plate 1 and the second arc plate 2 to increase the friction between the first arc plate 1, the second arc plate 2 and the artificial airway, and reduce the probability of the device falling off.
[0027] When in use, when the patient's artificial airway is in a weaning state, the first arc plate 1 and the second arc plate 2 can be directly clamped at the end of the artificial airway. At this time, the cover plate 3 can cover the end of the artificial airway, thereby reducing the risk of foreign objects falling into the artificial airway. During this process, if the air bag in the patient's artificial airway is not deflated, the patient's breathing depends on the opening of the artificial airway, that is, the external leakage end of the artificial airway. The air breathed by the patient will enter the artificial airway through the breathing gap, so as to facilitate the patient's weaning breathing training.
[0028] After the patient has been weaned off the ventilator for a period of time, the patient will be reconnected to the ventilator through the artificial airway to breathe. At this time, the device can be removed as a whole and placed separately, or the two cover plates 3 can be opened to the sides and the first arc-shaped part and the second arc-shaped plate 2 can be clamped down along the artificial airway to fix the device in the middle of the external leakage end of the artificial airway without affecting the use of the ventilator.
[0029] As the device moves up and down along the artificial airway, the second arc-shaped surface 20 and the third arc-shaped surface 21 can reduce the probability of jamming caused by the device and the external protrusion of the artificial airway.
[0030] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the clamping of the artificial airway, a fixing block 6 is fixedly connected to the rear side of the first arc plate 1 and the second arc plate 2. A placement groove 7 is opened on the outer side of the middle of each fixing block 6, and an elastic rope 8 is used together on the outer side of the two placement grooves 7.
[0031] It should be noted that the elastic rope 8 is made of elastic material, such as rubber, latex, plastic, etc., and has elasticity. Therefore, under its elastic action, after the first arc plate 1 and the second arc plate 2 are opened, a continuous tightening force is applied to the rear of the two, which makes it convenient to clamp the external leakage end of the artificial airway.
[0032] Furthermore, by Figures 1 to 3 As shown, in order to facilitate operation by medical staff, a first arc-shaped surface 9 is provided on the rear side of each fixing block 6, and an operation groove 10 is provided in the middle of the rear side of each fixing block 6.
[0033] In use, by setting the first arc surface 9, medical staff can easily open the first arc plate 1 and the second arc plate 2. By setting the operation groove 10, medical staff can easily use tweezers to remove the elastic rope 8.
[0034] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the storage of the device, a receiving groove 11 is provided on the outer side of the front part of the first arc plate 1 and the second arc plate 2. A rotating sleeve 12 is fixedly connected inside each receiving groove 11. A rotating rod 13 is fixedly connected to the lower side of each cover plate 3. Each rotating rod 13 is rotatably connected to the corresponding rotating sleeve 12.
[0035] In use, the receiving groove 11 is used to connect the rotating sleeve 12. By setting the rotating sleeve 12 and the rotating rod 13 to rotate, the rotating rod 13 and the cover plate 3 on its upper side can be connected.
[0036] Furthermore, by Figures 1 to 3As shown, in order to achieve a better covering effect, each rotating sleeve 12 has a rotating groove 14 inside, and each rotating groove 14 has a torsion spring 15 inside. The two ends of the torsion spring 15 are fixedly connected to the rotating sleeve 12 and the rotating rod 13 respectively.
[0037] It should be noted that the rotating groove 14 is used to accommodate the torsion spring 15. By setting the torsion spring 15, a rotational closing force can be continuously applied to the two cover plates 3, thereby making it convenient to cover the external leakage end of the artificial airway.
[0038] Furthermore, by Figures 1 to 3 As shown, in order to humidify the breathing gas during offline training, the humidification mechanism 5 includes multiple connecting rods 16 and a water tank 17. The upper side of the water tank 17 has multiple vent holes 18. The water tank 17 is filled with absorbent gel. The absorbent gel is a medical gel, which is a prior art, such as antimicrobial peptide hydrogel, or a reusable gel disclosed in DOI:10.1002 / adma.201806730, which will not be described in detail here.
[0039] In use, a water reservoir 17 is set up, and absorbent gel is placed inside the water reservoir 17. Before weaning training, an appropriate amount of normal saline, usually 5 ml, can be dripped into the water reservoir 17. The saline is absorbed by the absorbent gel. This design allows the inhaled air to flow through the upper side of the ventilator 18 during the patient's weaning breathing training. At this time, the liquid evaporated by the absorbent gel can humidify the air, thereby increasing the humidity of the breath and reducing the probability of sputum production.
[0040] When this invention is in use, firstly, when the patient's artificial airway is in a weaning state, the first arc plate 1 and the second arc plate 2 can be directly clamped at the end of the artificial airway. At this time, the cover plate 3 can cover the end of the artificial airway, thereby reducing the risk of foreign objects falling into the artificial airway. During this process, if the air bag in the patient's artificial airway is not deflated, the patient's breathing depends on the opening of the artificial airway, that is, the external leakage end of the artificial airway. The air breathed by the patient will enter the artificial airway through the breathing gap, so as to facilitate the patient's weaning breathing training.
[0041] After the patient has been weaned off the ventilator for a period of time, the patient will be reconnected to the ventilator through the artificial airway. At this time, the device can be removed as a whole and placed separately, or the two cover plates 3 can be opened to the sides and the first arc-shaped part and the second arc-shaped plate 2 can be clamped down along the artificial airway to fix the device in the middle of the external leakage end of the artificial airway without affecting the use of the ventilator.
[0042] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it is convenient for medical staff to cover the artificial airway, to hold the artificial airway, to operate, and to store the device, achieving a better covering effect and humidifying the breathing gas during off-ventilator training.
[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
