Description

Technical Field

[0001] This utility model relates to the field of critical care medical devices, and in particular to a pressure-visualized tracheostomy cannula. Background Technology

[0002] Tracheostomy is a surgical procedure performed in clinical practice to ensure a clear airway. It is commonly used in critically ill patients who require long-term mechanical ventilation support, patients with laryngeal obstruction who are unable to breathe normally, and other similar situations. In clinical settings such as intensive care and long-term respiratory support, the tracheostomy tube is a key device to ensure a clear airway for patients.

[0003] Current tracheostomy cannulas have significant shortcomings in terms of cuff pressure management, oxygen support, and infection control. Firstly, the cuffs of existing tracheostomy cannulas lack visual pressure monitoring, making it difficult for healthcare professionals to adjust cuff pressure accurately and in real time, potentially leading to airway damage or incomplete sealing. Secondly, in later care stages, when patients require oxygen therapy via the cannula, existing tracheostomy cannulas fail to provide integrated oxygen delivery devices and humidification systems, affecting patient comfort and treatment outcomes. Finally, when patients switch to cannula-based oxygen therapy, existing designs are prone to sputum splashing from the tracheostomy cannula, contaminating the tracheostomy site and surrounding environment, increasing the risk of cross-infection between medical staff and patients, and potentially allowing foreign objects to enter the body, threatening the patient's life. Therefore, it is necessary to design a pressure-visualizing tracheostomy cannula to address the problems existing in current tracheostomy cannula technology. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a pressure-visualized gas cutting sleeve.

[0005] A pressure-visualized tracheostomy cannula includes a tracheostomy tube and a tracheostomy fixation plate. The tracheostomy tube is the main body of the tracheostomy cannula. The tracheostomy fixation plate is located in the middle of the tube body and is used to fix the entire tracheostomy cannula at the surgical site in the patient's larynx. It also includes an oxygen connection tube, a humidification connection tube, a cuff tube, a cuff pressure monitoring tube, a subglottic suction tube, and a pressure detection device. The oxygen connection tube is connected to the upper middle part of the tracheostomy tube body for direct oxygen supply when the patient requires oxygen therapy. The humidification connection tube is connected to the upper middle part of the tracheostomy tube body. The humidification connecting tube can be connected to an infusion extension tube and then to a micropump or infusion pump. The humidification connecting tube is used to continuously humidify the tracheostomy tube. The tracheostomy tube is connected to a cuff tube. The cuff tube has a branch at the air delivery end and is connected to a cuff pressure measuring tube. The cuff pressure measuring tube has three viewing windows in sequence facing the tube opening. A pressure detection device is installed near the interior of each viewing window. The pressure detection device works with the three viewing windows to monitor the pressure inside the cuff tube. The side of the tracheostomy tube away from the cuff tube is connected to a subglottic suction tube.

[0006] Furthermore, it also includes a pressure detection component including a sliding rod and an indicator plate. The sliding rod is slidably connected to the inner wall of the airbag pressure measuring tube through a partition. The sliding rod and the inner wall of the airbag pressure measuring tube are slidably and sealed. An indicator plate is fixedly provided on the side of the sliding rod near the opening of the airbag pressure measuring tube. A spring is provided between the sliding rod and the partition on the inner wall of the airbag pressure measuring tube.

[0007] Furthermore, the first, second, and third ring windows are transparent windows in yellow, green, and red, respectively. The yellow ring window one indicates that the airbag pressure is insufficient, the green ring window two indicates that the airbag pressure is within a reasonable range (25-30 cmH2O), and the red ring window three indicates that the airbag pressure is too high.

[0008] Furthermore, the tracheostomy tube is detachably fitted with a tracheostomy connector, which can be securely closed at the tracheostomy tube connector to prevent sputum in the patient's trachea from splashing out from the tracheostomy tube connector, and at the same time prevent foreign objects from falling into the patient's airway through the tracheostomy tube.

[0009] Furthermore, the tracheostomy connector has a ring of anti-slip texture around its circumference. The anti-slip texture is used to increase the friction of the tracheostomy connector, making it easier for medical personnel to quickly install and remove the tracheostomy connector from the tracheostomy tube.

[0010] Furthermore, a connecting rope is provided on the outside of the tube wall near the connector of the tracheostomy cannula. The connecting rope is connected between the tracheostomy connector and the tracheostomy cannula. The connecting rope is used to prevent the tracheostomy connector from being lost after it is opened.

[0011] Beneficial effects:

[0012] 1. This utility model, through its detachable and assembleable tracheostomy connector, not only prevents sputum splashing but also avoids the possibility of foreign objects entering the patient's airway. Equipped with a subglottic suction tube, it effectively manages sputum, preventing it from splashing and contaminating the tracheostomy site and surrounding environment, reducing the risk of cross-infection between medical staff and patients, and further ensuring patient safety.

[0013] 2. This utility model can realize real-time visual monitoring of the internal pressure of the airbag by setting a visual panoramic window and an air pressure detection device in the airbag pressure measuring tube. This makes it easier for medical staff to quickly and accurately adjust the airbag pressure, reduce complications caused by improper air pressure, and reduce the workload of nurses who repeatedly monitor the airbag pressure.

[0014] 3. This utility model can also directly provide the patient with the required oxygen supply through the oxygen connection tube and the humidification connection tube, and continuously humidify the airway through the micro pump or infusion pump, improve the patient's comfort and breathing condition, avoid the formation of airway crusts, and reduce the risk of patient suffocation.

Detailed Implementation

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] A pressure-visualized gas cutting sleeve, such as Figures 1-4 As shown, the device includes a tracheostomy tube 1 and a tracheostomy fixation plate 2. The tracheostomy tube 1 is the main body of the tracheostomy cannula. The tracheostomy fixation plate 2 is located in the middle of the tube body of the tracheostomy tube 1. The tracheostomy fixation plate 2 is used to fix the entire tracheostomy tube at the surgical site of the patient's larynx. It also includes an oxygen connection tube 3, a humidification connection tube 5, a cuff tube 6, a cuff pressure monitoring tube 7, a subglottic suction tube 8, and a pressure detection device. The oxygen connection tube 3 is connected to the upper middle part of the tube body of the tracheostomy tube 1. The oxygen connection tube 3 is used to directly supply oxygen when the patient needs oxygen. The humidification connection tube 5 is connected to the upper middle part of the tube body of the tracheostomy tube 1. The humidification connection tube 5 can be connected to an external inhaler. The extension tube is connected to a micropump or infusion pump. The humidification connection tube 5 is used to continuously humidify the tracheostomy tube 1. The tube body of the tracheostomy tube 1 is connected to the cuff tube 6. The tube body of the cuff tube 6 is bifurcated at the air delivery end and connected to the cuff pressure measuring tube 7. The cuff pressure measuring tube 7 is provided with three ring windows 11, 12 and 13 in sequence facing the tube opening. A pressure detection device is provided near the ring windows of the cuff pressure measuring tube 7. The pressure detection device works with the ring windows 11, 12 and 13 to monitor the pressure in the cuff tube 6. The side of the tracheostomy tube 1 away from the cuff tube 6 is connected to the subglottic suction tube 8.

[0022] like Figure 3 and Figure 4 As shown, it also includes an air pressure detection component including a sliding rod 9 and an indicator plate 91. The sliding rod 9 is slidably connected to the inner wall of the airbag pressure measuring tube 7 through a partition. The sliding rod 9 and the inner wall of the airbag pressure measuring tube 7 are slidably sealed. An indicator plate 91 is fixedly installed on the side of the sliding rod 9 near the opening of the airbag pressure measuring tube 7. A spring 10 is provided between the sliding rod 9 and the partition on the inner wall of the airbag pressure measuring tube 7. The spring 10 acts on the sliding rod 9, causing the indicator plate 91 of the sliding rod 9 to contact the partition of the airbag pressure measuring tube 7. The air pressure in the airbag pressure measuring tube 7 will overcome the elastic force of the spring 10 and push the sliding rod 9, so that the indicator plate 91, together with the panoramic window 11, panoramic window 2 12 and panoramic window 3 13, can be used to know the real-time air pressure of the airbag.

[0023] like Figure 3 and Figure 4 As shown, the first ring window 11, the second ring window 12, and the third ring window 13 are transparent windows in yellow, green, and red, respectively. The yellow ring window 11 indicates that the air pressure in the airbag is insufficient, the green ring window 212 indicates that the air pressure in the airbag is within a reasonable range (25-30 cmH2O), and the red ring window 313 indicates that the air pressure in the airbag is too high. The nurse can quickly identify the pressure inside the airbag by observing the position of the ring windows on the indicator board 91.

[0024] like Figure 2As shown, the tracheostomy tube 1 is detachably equipped with a tracheostomy connector 4. The tracheostomy connector 4 can be tightly closed at the connector of the tracheostomy tube 1 to prevent sputum in the patient's trachea from splashing from the connector of the tracheostomy tube 1, and at the same time to prevent foreign objects from falling into the patient's airway through the tracheostomy tube 1.

[0025] like Figure 1 and Figure 2 As shown, the tracheostomy connector 4 has a ring of anti-slip texture around its circumference. The anti-slip texture is used to increase the friction of the tracheostomy connector 4, making it easier for medical personnel to quickly install and remove the tracheostomy connector 4 from the tracheostomy tube 1. A connecting rope 41 is provided on the outside of the tube wall near the connector of the tracheostomy tube 1. The connecting rope 41 is connected between the tracheostomy connector 4 and the tracheostomy tube 1. The connecting rope 41 is used to prevent the tracheostomy connector 4 from being lost after it is opened.

[0026] When using this tracheostomy cannula, the pressure changes inside the air bladder are monitored in real time through a dynamic pressure feedback system. The internal pressure of the air bladder tube 6 pushes the sliding rod 9 in the pressure measuring tube to move outward against the resistance of the spring 10, causing the indicator plate 91 to interact with the viewing window: when the indicator plate 91 aligns with the yellow viewing window (pressure < 25 cmH2O), it indicates that the air bladder pressure is insufficient and needs to be replenished to prevent leakage; when it moves to the green viewing window (25-30 cmH2O), it indicates that the pressure is within a safe range, and the tension of the spring 10 is balanced with the air bladder pressure to protect the airway mucosa; if it enters the red viewing window (> 30 cmH2O), it warns of excessive compression and the need for emergency decompression. At the same time, the oxygen connection tube 3 directly supplies oxygen. To maintain respiratory support, the humidification connection tube 5 precisely infuses humidification fluid through an external micropump, forming a continuous gas-liquid circulation to prevent sputum blockage. The independent channel design of the two tubes takes into account both functionality and pollution prevention requirements. The subglottic suction tube 8 can periodically clear secretions above the cuff. It is equipped with a detachable tracheostomy connector 4 with anti-slip texture to prevent sputum splashing and foreign object intrusion, and ensures rapid opening and closing in emergency operations. The connecting rope 41 connected to the tracheostomy connector 4 can avoid the risk of loss. The mechanical pressure measurement structure feedback replaces the traditional manual pressure measurement. On the basis of maintaining the comprehensive effectiveness of airway humidification, oxygen supply and secretion management, it realizes passive visual monitoring of cuff pressure, which significantly improves the safety of clinical operations and nursing efficiency.

[0027] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
