Description

Technical Field

[0001] This utility model relates to the field of gas cut-off sleeve sealing technology, and in particular to an adjustable sealing device for gas cut-off sleeves. Background Technology

[0002] Tracheotomy involves cutting open the cervical trachea and inserting a metal tracheostomy tube or a silicone tracheostomy tube. It is a common surgical procedure to relieve respiratory distress caused by laryngeal dyspnea, respiratory dysfunction, or lower respiratory tract secretion retention.

[0003] A utility model patent document with publication number CN213131414U discloses a plug for a tracheostomy cannula. By setting the plug body into an inverted frustum shape, it can adapt to various sizes of tracheostomy cannulas. The first conduit extends the through hole of the body upwards, and a cap is used for sealing. The cap is easy to remove and remove with minimal movement, reducing the pain to the patient during the cap removal process. By setting several annular grooves with elastic rubber rings fixed on the outside of the plug body, the plug body is effectively prevented from loosening from the tracheostomy cannula. By setting an expansion end at the free end of the pull bar, the cap body can be quickly removed in case of emergency such as breathing difficulties. By setting a second conduit on the cap and using a common infusion regulator to compress the second conduit to achieve partial and gradual tube blockage, it is convenient for medical staff to assess the patient's spontaneous breathing status.

[0004] While the aforementioned plugs for tracheostomy cannulas can solve the corresponding technical problems, they achieve partial and gradual plugging by pressing the second catheter with an infusion regulator. However, the infusion regulator has difficulties in accurately controlling the air flow, and inappropriate air intake can lead to serious complications. Furthermore, the adjusting wheel on the infusion regulator is prone to accidental rotation, resulting in inaccurate air intake adjustment. Secondly, existing catheters are insufficient to accommodate different sizes of tracheostomy cannulas, requiring replacement of the corresponding catheter for each type, which consumes more materials and reduces work efficiency. Therefore, an adjustable plugging device for tracheostomy cannulas is proposed. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-4This utility model provides an adjustable sealing device for a gas-cutting sleeve, including a main body assembly 100, a connecting pipe 200 connected to the gas-cutting sleeve, a blocking assembly 300 for adjusting the air intake, and a rotating assembly 400 for locking the blocking assembly 300. The connecting pipe 200 is located at the bottom of the main body assembly 100, the blocking assembly 300 is located in the inner cavity of the main body assembly 100, and the rotating assembly 400 is located between the main body assembly 100 and the blocking assembly 300. The blocking assembly 300 includes a shaft 310 that is horizontally movably connected to the inner cavity of the main body assembly 100. A baffle 320 is fixedly connected to both sides of the surface of the shaft 310, and the baffle 320 and the main body assembly 100 are arranged in concentric circles.

[0028] The main component 100 includes an air cover 110, with a connecting pipe 120 integrally formed at the bottom of the air cover 110. The connecting pipe 120 is threaded to the top of the connecting pipe 200. One end of the shaft 310 is rotatably connected to the inner wall of the air cover 110. The main component 100 can provide an installation base for the shielding component 300 and the rotating component 400.

[0029] An air circulation channel is formed between the air hood 110, the connecting pipe 120, and the connecting pipe 200.

[0030] The diameter of the bottom end of the 200 connecting pipe is smaller than that of the top end, which can accommodate various sizes of gas cutting sleeves.

[0031] The central axis of the shaft 310 is perpendicular to the central axis of the air hood 110, and the diameter of the baffle 320 is equal to the inner diameter of the air hood 110. When the baffle 320 is horizontal in the inner cavity of the air hood 110, it can block the air flow channel.

[0032] The rotating assembly 400 includes a knob 410 and a support 420. The knob 410 contacts one side of the support 420. The support 420 is integrally formed on the outer surface of the air cover 110. The support 420 and the air cover 110 are provided with a through hole 430 for the shaft 310 to pass through. The other end of the shaft 310 passes through the through hole 430 to one side of the support 420. A snap-fit ​​component is provided between the knob 410 and the support 420. A telescopic component is provided between the knob 410 and the shaft 310. A finger plate 411 is fixedly connected to the side of the knob 410 away from the support 420. The finger plate 411 can increase the contact area between the hand and the knob 410, making it convenient to turn or pull the knob 410.

[0033] The snap-fit ​​component includes a positioning rod 440 fixedly connected to the surface of the knob 410. The support 420 has several equidistantly distributed positioning holes 450 on the side near the knob 410. One end of the positioning rod 440 is snapped into the corresponding positioning hole 450. The snap-fit ​​component can fix the knob 410 and the blocking component 300 at an angle, so that the blocking component 300 can be stably maintained at a certain angle, effectively preventing the blocking component 300 from loosening.

[0034] Among them, the lines connecting the centers of several positioning holes 450 form an arc. The arc, the through hole 430, and the knob 410 are arranged in concentric circles. The lines connecting the two outermost positioning holes 450 and the through hole 430 are perpendicular to each other. When the shielding component 300 is rotated clockwise to its maximum limit in the air cover 110, the shielding component 300 can be in a vertical state to achieve the maximum air intake effect. When the shielding component 300 is rotated counterclockwise to its maximum limit in the air cover 110, the shielding component 300 can be in a horizontal state to achieve the sealing effect.

[0035] The telescopic component includes a rod 460 fixedly connected to one side of the knob 410. The end of the shaft 310 has a socket 311 that matches the rod 460. The rod 460 extends movably through the inner cavity of the socket 311. A through groove 470 is provided on the rod 460. A slider 480 is slidably connected to the inner cavity of the through groove 470. Both sides of the slider 480 are fixedly connected to the inner wall of the socket 311. The telescopic component can achieve both a movable connection between the knob 410 and the shaft 310, so that when the knob 410 drives the positioning rod 440 to engage or disengage from the positioning hole 450, the knob 410 will not separate from the shaft 310. It can also achieve linkage between the knob 410 and the shaft 310, so that when the knob 410 rotates, it can drive the shaft 310 and the baffle 320 to rotate synchronously, thereby achieving the effect of adjusting the air intake.

[0036] A spring 490 is fixedly connected to the inner cavity of the insertion hole 311. One end of the spring 490 is fixedly connected to the insertion rod 460. The insertion rod 460 can drive the knob 410 to move automatically toward the support 420, thereby effectively preventing the positioning rod 440 from disengaging from the inner cavity of the positioning hole 450.

[0037] The working principle of this utility model is as follows: The bottom end of the connecting pipe 200 is inserted into the interface of the air-cutting sleeve. The knob 410 is pulled by the finger plate 411. The knob 410 causes the insertion rod 460 and the through groove 470 to move within the cavity of the insertion hole 311. The slider 480 slides within the cavity of the through groove 470, and the spring 490 is stretched. The knob 410 also causes the positioning rod 440 to move synchronously until the positioning rod 440 moves out of the cavity of the positioning hole 450, thus unlocking the shielding component 300. Then, the knob 410 is turned using the finger plate 411. The knob 410 causes the insertion rod 460, the through groove 470, the slider 480, the shaft 310, and the baffle 320 to rotate synchronously, causing the baffle 320... The air hood 110 rotates around the shaft 310, and the knob 410 also drives the positioning rod 440 to rotate synchronously, so that the positioning rod 440 rotates to the required position, such as when the air intake is adjusted to one-quarter. At this time, the positioning rod 440 is aligned with the corresponding positioning hole 450. Then, the finger plate 411 is slowly released. Through the elastic restoring force of the spring 490, the insertion rod 460 drives the through groove 470, the knob 410, the finger plate 411 and the positioning rod 440 to move synchronously until the positioning rod 440 is locked into the corresponding positioning hole 450, which locks the shielding component 300 and keeps the shielding component 300 stably in this state, thereby completing the adjustment of the air intake.

[0038] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
