Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a tracheotomy cannula plugging device. Background Art

[0002] After tracheotomy, due to the friction between the tracheotomy cannula and the respiratory mucosa, the discomfort of the patient is increased, and at the same time, the speech function is affected. Therefore, the cannula should be removed as early as possible after the patient's condition is stable. Before removing the tracheotomy tube, it is necessary to block the outer opening of the tracheotomy cannula: first block it semi-occluded for 48 hours, and then fully occluded for 24 hours. Observe the breathing condition. If there is dyspnea, the degree of occlusion should be adjusted. A safe and effective trial occlusion before extubation is very important.

[0003] In the past, the commonly used tracheotomy cannula plugging devices in clinics were wooden plugs, rubber bottle stoppers, cotton swabs wrapped with adhesive tape, etc. These items have the disadvantages of being easily coughed out, easily aspirated, and not easily disinfected. Moreover, there is no semi-occlusion process during use, and complete occlusion makes it difficult for patients to adapt, and symptoms such as chest tightness, abnormal breathing, decreased arterial oxygen partial pressure, and even dyspnea are likely to occur. During the occlusion period, operations such as sputum suction and oxygen inhalation are inconvenient, increasing the discomfort and tension of the patient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tracheotomy cannula plugging device that can gradually reduce the gas inflow and outflow volume, enabling the patient's lung function to have an adaptation process.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A tracheotomy cannula plugging device includes an intubation tube. A first groove is formed on the outer surface of the intubation tube. An airbag is arranged inside the first groove. A second groove is formed on the outer surface of the intubation tube along its length direction, and the second groove communicates with the first groove. A connecting tube is connected to the outer surface of the airbag, and the connecting tube is arranged inside the second groove. A housing is installed at the end of the intubation tube. An air charging and discharging mechanism capable of charging and discharging air from the airbag is arranged on the outer surface of the housing. A flexible tube is arranged inside the housing, and one end of the flexible tube extends to the outside of the housing, and the other end of the flexible tube is connected to the intubation tube. An adjusting mechanism capable of adjusting the gas inflow and outflow volume of the flexible tube is arranged inside the housing.

[0007] Thus, by inserting the intubation tube into the metal cannula in the patient's neck and inflating the airbag through the air charging and discharging mechanism, it can expand and tightly press against the inner wall of the metal cannula, thereby realizing the fixation of the device and avoiding the situation of falling during use. Moreover, the airbag can also play a sealing role to avoid air leakage. Through the setting of the adjusting mechanism, the gas inflow and outflow volume of the flexible tube can be adjusted, so as to gradually reduce the gas inflow and outflow volume, enabling the patient's lung function to have an adaptation process and reducing the discomfort and tension of the patient.

[0008] Further, the inflation and deflation mechanism includes a cylinder installed on the outer surface of the housing, and the connecting pipe is connected to the cylinder. A first threaded rod penetrates through and is threadedly connected to the inside of the cylinder. A piston is arranged inside the cylinder, and the first threaded rod is connected to the piston.

[0009] When the first threaded rod is rotated clockwise, it can penetrate deeper into the cylinder and drive the piston to advance, pushing the gas inside the cylinder into the connecting pipe and then into the airbag to make it expand. When the first threaded rod is rotated counterclockwise, it is driven to be pulled outwards, driving the piston to contract inside the cylinder, and then the gas inside the airbag can be pumped into the cylinder to relieve the pressure of the airbag.

[0010] Further, the adjustment mechanism includes a second threaded rod with a pair of reverse threads rotatably installed inside the housing. Two nuts are respectively installed on the pair of reverse threads of the second threaded rod. One side outer surfaces of the two nuts are both connected with clamping plates. A limiting groove is opened on the side surface of the housing. Limiting blocks are installed on the other side outer surfaces of the two nuts, and the limiting blocks are arranged inside the limiting groove.

[0011] Due to the setting of the reverse threads and the limiting effect of the limiting groove and the limiting blocks on the nuts, when the second threaded rod is rotated clockwise, the two nuts can be driven to move inwards simultaneously, and the two clamping plates are driven to squeeze the hose at the same time, causing the hose to deform and reducing the gas inflow and outflow volume. Therefore, by adjusting the squeezing degree of the clamping plates on the hose, the purpose of adjusting the gas inflow and outflow volume can be achieved.

[0012] Further, a limiting ring is sleeved on the outer surface of the intubation tube.

[0013] Through the setting of the limiting ring, the distance of the intubation tube inserted into the metal sleeve can be restricted, avoiding the discomfort of the patient caused by excessive insertion.

[0014] Further, scale lines are arranged on the side surface of the housing, and the scale lines are distributed along the height direction of the limiting groove.

[0015] Since the limiting blocks will also be driven to move when the nuts drive the clamping plates to squeeze the hose, the squeezing degree of the clamping plates on the hose can be known by observing the scale lines, and thus it is convenient to finely adjust the gas inflow and outflow volume.

[0016] Further, knobs are installed at the ends of the first threaded rod and the second threaded rod, and anti-slip patterns are opened on the outer surfaces of the knobs.

[0017] Through the setting of the knobs, it is convenient to rotate the first threaded rod and the second threaded rod, and the situation of hand slipping is avoided. Description of the Drawings

Specific embodiments

[0023] The following describes the present utility model in detail with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a tracheotomy cannula plugging device includes an intubation tube 100. A first groove 101 is formed on the outer surface of the intubation tube 100. An airbag 102 is arranged inside the first groove 101. A second groove 106 is formed on the outer surface of the intubation tube 100 along its length direction, and the second groove 106 communicates with the first groove 101. A connecting tube 103 is connected to the outer surface of the airbag 102, and the connecting tube 103 is arranged inside the second groove 106. One end of the intubation tube 100 is provided with a housing 104. An air charging and discharging mechanism 200 capable of charging and discharging the airbag 102 is arranged on the outer surface of the housing 104. A hose 105 is arranged inside the housing 104, one end of the hose 105 extends to the outside of the housing 104, and the other end of the hose 105 is connected to the intubation tube 100. An adjusting mechanism 300 capable of adjusting the gas inflow and outflow of the hose 105 is arranged inside the housing 104.

[0025] During use, first insert the intubation tube 100 into the metal cannula in the patient's neck. Then, inflate the airbag 102 through the inflation and deflation mechanism 200 to make the airbag 102 expand and press against the inner wall of the metal cannula, thereby fixing the device and sealing the connection with the metal cannula. Subsequently, through the setting of the adjustment mechanism 300, the gas inflow and outflow volume of the hose 105 can be adjusted. In the initial stage, reduce the gas inflow and outflow volume of the hose 105 by about half, and continuously observe the patient's breathing condition for 48 hours. If the patient's breathing condition is stable, the gas inflow and outflow volume can be further reduced until it is completely blocked, and observe for 24 hours. During the whole process, if the patient shows abnormal conditions such as difficulty in breathing, the gas inflow and outflow volume should be immediately increased through the adjustment mechanism 300 to ensure the patient's safety. Medical staff can flexibly adjust the gas inflow and outflow volume according to the patient's breathing condition, enabling the patient's lung function to have an adaptation process and reducing the patient's discomfort and sense of tension.

[0026] Specifically, the inflation and deflation mechanism 200 includes a cylinder body 201 installed on the outer surface of the housing 104, and the connecting pipe 103 is connected to the cylinder body 201. A first threaded rod 202 penetrates and is threadedly connected inside the cylinder body 201. A piston 203 is arranged inside the cylinder body 201, and the first threaded rod 202 is connected to the piston 203. When the first threaded rod 202 is rotated clockwise, it can penetrate deeper into the cylinder body 201 and drive the piston 203 to advance, pushing the gas inside the cylinder body 201 into the connecting pipe 103 and then into the airbag 102 to make it expand. When the first threaded rod 202 is rotated counterclockwise, it drives it to be pulled outwards, driving the piston 203 to contract inside the cylinder body 201, and then the gas inside the airbag 102 can be pumped into the cylinder body 201 to deflate the airbag 102.

[0027] Specifically, the adjustment mechanism 300 includes a second threaded rod 301 with a pair of reverse threads rotatably installed inside the housing 104. Two nuts 302 are respectively installed on the pair of reverse threads of the second threaded rod 301. On the outer surface of one side of the two nuts 302, clamping plates 303 are respectively connected. A limiting groove 304 is formed on the side surface of the housing 104. On the outer surface of the other side of the two nuts 302, limiting blocks 305 are respectively installed, and the limiting blocks 305 are arranged inside the limiting groove 304. Due to the setting of the reverse threads and the limiting effect of the limiting groove 304 and the limiting blocks 305 on the nuts 302, when the second threaded rod 301 is rotated clockwise, the two nuts 302 can be driven to move inwards simultaneously, and the two clamping plates 303 are driven to squeeze the hose 105 simultaneously, causing the hose 105 to deform and reducing the gas inflow and outflow volume. Therefore, by adjusting the squeezing degree of the clamping plates 303 on the hose 105, the purpose of adjusting the gas inflow and outflow volume can be achieved.

[0028] Specifically, a limiting ring 400 is sleeved on the outer surface of the intubation tube 100. Through the setting of the limiting ring 400, the distance of the intubation tube 100 inserted into the metal cannula can be limited, avoiding discomfort caused by excessive insertion for the patient.

[0029] Specifically, scale lines 500 are provided on the side surface of the housing 104, and the scale lines 500 are distributed along the height direction of the limiting groove 304. Since the nut 302 drives the clamping plate 303 to squeeze the hose 105 and also drives the limiting block 305 to move, the squeezing degree of the clamping plate 303 on the hose 105 can be known by observing the scale lines 500, thus facilitating the fine adjustment of the gas inflow and outflow volume.

[0030] Specifically, knobs 600 are installed at the ends of the first threaded rod 202 and the second threaded rod 301. Anti-slip threads are provided on the outer surface of the knob 600. Through the setting of the knob 600, it is convenient to rotate the first threaded rod 202 and the second threaded rod 301, and the situation of hand slipping is avoided.

[0031] The above is the detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several equivalent substitutions or obvious variations are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
