Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel tracheotomy tube plugging device. Background Technology

[0002] In recent years, the number of patients undergoing tracheostomy has been increasing year by year. Studies have shown that the tracheostomy rate among critically ill neurological patients is as high as 15-45%. Tracheostomized patients are highly susceptible to pulmonary infections due to changes in their ventilation structure, and also experience difficulties such as speech impairment, swallowing difficulties, and nursing challenges. Therefore, the removal of the tracheostomy tube in patients during the recovery period is particularly important. Before tracheostomy tube removal, a tube occlusion tolerance test is routinely performed. Patients who tolerate direct tube occlusion for 24-48 hours can be considered for extubation. The purpose of tube occlusion is to simulate whether the patient can tolerate extubation.

[0003] Traditional metal gas cutting sleeves, when used, such as Figure 1 As shown, first insert the bullet core a into the metal tracheostomy cannula b until the head is exposed, then insert the entire device into the body. Use the bullet core a to expand the tissue, preventing the metal tracheostomy cannula b from directly contacting and damaging the tissue upon entry. Continue until the metal tracheostomy cannula b is inserted into the airway c, then remove the bullet core a. Figure 2 , Figure 3 As shown. Due to the relatively long length of the metal tracheostomy cannula b, which occupies a significant amount of airway space, occupancy of the cannula b does not fully simulate the extubation state and can easily trigger respiratory distress, causing some patients to be unable to tolerate routine tracheostomy occlusion. If, in order to simulate the extubation state as closely as possible and alleviate respiratory distress caused by cannula length factors, the metal tracheostomy cannula b is pulled outwards to a certain length after occlusion, other problems may arise, such as the metal tracheostomy cannula b potentially dislodging or being accidentally touched by the patient, increasing the patient's suffering. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel tracheostomy tube plugging device, which aims to solve the technical problems existing in the prior art, such as the long length of traditional metal tracheostomy tubes, the tube body occupying a large amount of airway ventilation space, the inability to completely simulate the extubation state after plugging, the easy occurrence of breathing difficulties, and the possibility of falling off or being accidentally touched by the patient if pulled out to a certain length, increasing the patient's suffering.

[0005] The technical solution of this utility model is: a novel air-cutting plugging device, comprising an outer tube, a nut, a soft inner core, and a metal inner core. The outer tube includes a smooth outer tube body at the front end and an outer tube gasket connected to the rear end of the outer tube body. An insertion channel is provided inside the outer tube. The nut includes a nut body and a nut gasket connected to the front end of the nut body. A connecting channel is provided inside the nut, and the nut is fitted onto the outer tube body of the outer tube through the connecting channel. The nut and the outer tube are adjustable. The soft inner core includes an inner core body and a metal inner core connected to the inner core. The main body has multiple expanding flaps at its front end and an inner core gasket connected to the rear end of the inner core body. The soft inner core has a hollow channel inside. The inner core body of the soft inner core is installed in the insertion channel of the outer tube. The expanding flaps are located outside the front end of the insertion channel and are used to expand outward to achieve relative positioning between the soft inner core and the outer tube. The inner core gasket is also connected to a plug, which can cooperate to block the rear end of the hollow channel to achieve tube blocking. The metal inner core has a bullet-shaped front end and can be inserted into the insertion channel of the outer tube to deliver the outer tube into the body.

[0006] Furthermore, in this utility model, the outer tube body and the outer tube gasket are integrally formed, and the insertion channel extends along the length direction of the outer tube and passes through both ends of the outer tube.

[0007] Furthermore, the front end of the insertion channel in this invention has a radially inwardly contracting section, which is used to limit the insertion of the metal inner core.

[0008] Furthermore, the outer tube in this utility model is made of metal, and the outer surface of the rear end of the outer tube body is provided with external threads.

[0009] Furthermore, in this utility model, the nut body and the nut washer are integrally formed, and the connecting channel extends along the length of the nut and passes through both ends of the nut.

[0010] Furthermore, the nut in this utility model is made of metal or plastic, and the inner wall of the connecting channel is provided with an internal thread that matches the external thread on the outer sleeve.

[0011] Furthermore, the number of expansion lobes in this invention is no less than three, and the multiple expansion lobes are evenly arranged at the front end of the inner core body and are in an outward state.

[0012] Furthermore, in this utility model, the inner core body, the expansion leaflet, and the inner core gasket are integrally formed, and the hollow channel extends along the length direction of the soft inner core and penetrates both ends of the soft inner core.

[0013] Furthermore, the soft inner core described in this utility model is made of any one of silicone, rubber, or silicone.

[0014] Furthermore, in this invention, the plug head and the inner core gasket are connected by a connecting wire.

[0015] Compared with the prior art, this invention has the following advantages: It can greatly reduce the volume of the outer tube occupying the airway ventilation space, help better simulate the extubation state, improve the problem of breathing difficulties caused by the tube, and give patients who cannot tolerate conventional tube occlusion an opportunity for extubation; the nut can be screwed and adjusted, and can cooperate with the expansion flap of the soft inner core to fix the whole device, making it less likely to fall off the patient; the overall length of the device is shorter than that of conventional metal tracheostomy tubes, making it less likely for patients to accidentally touch it, thereby avoiding increased pain; the soft inner core of the device is hollow inside, and the plug at the rear end can be used to block the tube, and suctioning can be performed by opening the plug, which is convenient to operate.

[0031] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] Combination Figures 4 to 8 The figure shows a specific embodiment of a novel air-cutting and plugging device of this utility model, with reference to... Figure 4 It mainly includes an outer tube 1, a nut 2, a soft inner core 3, and a metal inner core 6. The outer tube 1 includes an outer tube body 101 with a smooth front end and an outer tube gasket 102 connected to the rear end of the outer tube body 101. The outer tube body 101 and the outer tube gasket 102 are integrally formed. The inner part of the outer tube 1 is provided with an insertion channel 1a, which extends along the length of the outer tube 1 and passes through both ends of the outer tube 1. The front end of the insertion channel 1a has a radially inwardly contracting section 1b, which is used to limit the insertion of the metal inner core 6.

[0034] The outer tube 1 is made of metal. The outer surface of the outer tube body 101 at the rear end of the outer tube 1 is provided with external thread 1c, which is used to fit the screw nut 2.

[0035] The nut 2 includes a nut body 201 and a nut washer 202 connected to the front end of the nut body 201. The nut body 201 and the nut washer 202 are integrally formed. The nut 2 has a connecting channel 2a inside, which extends along the length of the nut 2 and passes through both the front and rear ends of the nut 2.

[0036] The nut 2 is made of metal or plastic, and the inner wall of the connecting channel 2a has an internal thread 2b that mates with the external thread 1c on the outer tube body 101. The nut 2 is fitted onto the outer tube 1 and its position on the outer tube 1 can be adjusted by screwing it on.

[0037] The soft inner core 3 includes an inner core body 301, multiple expansion lobes 302 connected to the front end of the inner core body 301, and an inner core gasket 303 connected to the rear end of the inner core body 301. The number of expansion lobes 302 is not less than three, and the multiple expansion lobes 302 are evenly arranged at the front end of the inner core body 301 and are in an outwardly flared state. The inner core body 301, expansion lobes 302, and inner core gasket 303 are integrally formed.

[0038] The soft inner core 3 has a hollow channel 3a inside, which extends along the length of the soft inner core 3 and passes through both ends of the soft inner core 3. The soft inner core 3 is made of any one of silicone, rubber, or silicone.

[0039] The inner core body 301 of the soft inner core 3 is installed in the insertion channel 1a of the outer tube 1, and the expansion leaf 302 is located outside the front end of the insertion channel 1a to achieve relative positioning between the soft inner core 3 and the outer tube 1 by expanding to an outward state.

[0040] The inner core gasket 303 of the soft inner core 3 is also connected to a plug 4 via a connecting line 5. The plug 4 can cooperate to plug the rear end of the hollow channel 3a to achieve pipe plugging.

[0041] The metal inner core 6 has a bullet-shaped front end and can be inserted into the insertion channel 1a of the outer tube 1 to deliver the outer tube 1 into the body.

[0042] In practical use, the air-cutting and plugging device of this utility model is first screwed onto the rear end of the outer sleeve 1, as follows: Figure 5 As shown, the inner metal core 6 (which functions the same as the bullet-shaped inner core a used in the metal gas cutting sleeve b) is then inserted into the rear end of the insertion channel 1a of the outer sleeve 1 until the bullet-shaped front end of the inner metal core 6 contacts the constricted section 1b at the front end of the insertion channel 1a; then the entire assembly is inserted into the body, as shown. Figure 6 Similarly, the metal inner core 6 is used to expand the tissue, preventing the outer tube 1 from directly contacting and damaging the tissue when it is inserted into the body. The metal inner core 6 is then removed after the outer tube 1 is inserted into the airway c. Figure 7 As shown, at this point, the outer tube 1 needs to be inserted deep into the airway c to facilitate the insertion of the soft inner core 3; then, manually retract the expansion flap 302 at the front end of the soft inner core 3, and then insert it from the rear end of the insertion channel 1a of the outer tube 1. After it is fully inserted and extends from the front end of the insertion channel 1a, the expansion flap 302 will automatically open (the contraction section 1b at the front end of the insertion channel 1a will not affect the insertion of the expansion flap 302). Figure 8As shown, at this point, the dilator flap 302 is located within airway c; then, the entire device is slowly pulled outwards a certain length until a certain resistance is encountered and then stopped, indicating that the dilator flap 302 is in contact with the inner wall of airway c. Next, the nut 2 is tightened until it contacts the patient's skin and subcutaneous tissue d, at which point the entire device is fixed. Finally, the plug 4 is inserted to seal the airway. Figure 9 As shown, by opening the stopper 4, sputum can be suctioned through the hollow channel 3a of the soft inner core 3, which is convenient to operate.
