Description

Technical Field

[0001] The utility model belongs to the technical field of pipe blocking, and in particular relates to a plugging head structure which is easy to disassemble and assemble and a tracheotomy pipe blocking device. Background Art

[0002] Tracheotomy is a commonly used emergency technique in clinical practice. After the patient's condition stabilizes and respiratory muscle function recovers, the tracheal tube or endotracheal intubation will be removed. However, the tube must be blocked for observation before removal. The tube can only be removed after 24-48 hours of observation without breathing difficulties. This is to allow the patient to gradually adapt to the function of autonomous breathing. Therefore, a plug is needed to block the tracheal tube.

[0003] Existing, when the tracheal tube is blocked and sealed, the tube is generally sealed by inserting a plug into the air inlet of the tube, and after sealing, adhesive tape is used to wrap around the connection between the plug and the tube, so as to fix the plug and enhance the stability of the connection. However, when the patient is in the observation period and his spontaneous breathing function is still unable to breathe normally, he needs to use the tracheal tube again for breathing. However, since the plug is wrapped around the air inlet of the tube by adhesive tape, when removing the plug, the wrapped adhesive tape needs to be opened in turn to remove the plug sealed at the air inlet of the tube. This requires a certain amount of adhesive tape to be wrapped when sealing the tracheal tube, and the wrapped adhesive tape needs to be removed when opening the tracheal tube later, which makes it more troublesome to seal or remove the plug, greatly increasing the workload of medical staff.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] (1) By pulling the pin out of the pin hole and pressing the moving rod into the sliding cylinder to move it, the moving rod moves and drives the clamping rod to move and compress the spring. At this time, the annular bottom of the plug is correctly inserted into the annular groove at the top of the connecting seat, and the hand pressing the moving rod is released. The spring returns to the original position and drives the moving rod to move out of the sliding cylinder. The moving rod moves and drives the clamping rod toward one end of the clamping slot, so that the clamping rod and the clamping slot are clamped together, thereby clamping and fixing the plug and the connecting seat. When removing the plug, you only need to press the moving rod into the sliding cylinder to disengage the clamping rod from the clamping slot, and then you can remove the plug. The disassembly is relatively convenient, which greatly reduces the workload of medical staff.

[0019] (2) After the plug is clamped with the connecting seat, the turntable is rotated to drive the screw to rotate. When the screw rotates, the sleeve connected with the thread moves toward the end close to the air inlet, and when the sleeve moves, the sealing block follows the movement, so that the sealing block contacts the air inlet and seals inside the air inlet, thereby sealing the air inlet of the connecting seat at the top of the cannula, thereby blocking the cannula.

[0020] (3) By setting a heat and moisture exchange shell in the cannula, when the patient breathes through the cannula and the gas is exhaled from the cannula through the air inlet, the heat and moisture exchange layer in the heat and moisture exchange shell captures the warm and moist gas during exhalation and releases it to the patient when the patient inhales through the air inlet, thereby maintaining a certain humidity and temperature in the patient's respiratory airway and avoiding airway dryness caused by water loss.

[0030] The fixing component 3 is arranged in the connecting seat 1 and is used to fix the plug 2 after being sealed with the connecting seat 1. The plug 2 is fixed to the top of the connecting seat 1 by the clamping rod 4 of the fixing component 3 and the clamping groove 5 in the plug 2.

[0031] The fixing assembly 3 includes a sliding cylinder 8 and a moving rod 9. The sliding cylinder 8 is arranged in a mounting groove 10 on one side of the connecting seat 1. The moving rod 9 is slidably inserted in the sliding cylinder 8. A sliding groove 11 is provided at the bottom of the sliding cylinder 8.

[0040] The plugging structure and tracheotomy plugging device that are easy to disassemble and assemble are constructed by pulling the plug 16 out of the plug hole 15 and pressing the moving rod 9 to move into the sliding cylinder 8. The moving rod 9 moves while driving the clamping rod 4 to move and compress the spring 13. At this time, the annular bottom of the plug 2 is correctly inserted into the annular groove at the top of the connecting seat 1, and the hand pressing the moving rod 9 is released. The spring 13 returns to its original position and drives the moving rod 9 to move out of the sliding cylinder 8. The moving rod 9 moves while driving the clamping rod 4 to one end of the clamping slot 5. , so that the clamping rod 4 is clamped with the clamping groove 5, so that the plug 2 and the connecting seat 1 are clamped and fixed, and after the clamping rod 4 is clamped with the clamping groove 5, the moving rod 9 is limited by plugging the pin 16 with the pin hole 15, so as to avoid the loosening of the clamping connection between the clamping rod 4 and the clamping groove 5 caused by the movement of the moving rod 9 due to accidental contact, and when removing the plug 2, it is only necessary to press the moving rod 9 into the sliding cylinder 8 to disengage the clamping rod 4 from the clamping groove 5, and the plug 2 can be removed. The disassembly is relatively convenient, which greatly reduces the workload of medical staff.

[0041] When the plug 2 is clamped with the connecting seat 1, the turntable 18 is rotated in the forward direction so that the turntable 18 drives the screw rod 19 to rotate in the forward direction. When the screw rod 19 rotates, it drives the threaded sleeve 20 to move toward the end close to the air inlet 6, and when the sleeve 20 moves, it drives the sealing block 7 to follow the movement, so that the sealing block 7 contacts with the air inlet 6 and seals in the air inlet 6, and the air inlet 6 of the connecting seat 1 at the top of the insert 23 is sealed, thereby blocking the insert 23, and the sealing gasket 22 is provided at the sealing point between the sealing block 7 and the air inlet 6, which can greatly enhance the sealing between the sealing block 7 and the air inlet 6 to avoid air leakage. When it is necessary to remove the plug 2, the turntable 18 can be reversed in advance to drive the screw rod 19 to rotate in the reverse direction, so that the sleeve 20 drives the sealing block 7 to move toward the end close to the turntable 18, and breaks away from the seal with the air inlet 6, so that the plug 2 can be removed by pressing the fixing component 3.

[0042] By arranging a heat and moisture exchange shell 25 in the cannula 23, when the patient breathes through the cannula 23 and the gas is exhaled out of the cannula 23 through the air inlet 6, the heat and moisture exchange layer 27 in the heat and moisture exchange shell 25 captures the exhaled warm and moist gas during exhalation and releases it to the patient when the patient inhales through the air inlet 6, thereby maintaining a certain humidity and temperature in the patient's respiratory airway and avoiding airway dryness caused by water loss.
