Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 3, an endotracheal intubation distraction device according to an embodiment of the present invention includes a sleeve body 1 and a driving rod 2; the sleeve body 1 comprises a straight cylinder section 11 and a cone section 12, the top end of the cone section 12 is provided with an opening 121 and is suitable for inserting a tracheal cannula, the bottom end of the cone section 12 is connected with the straight cylinder section 11, and the side wall of the cone section 12 is provided with a gap 122 for the side wall of the cone section 12 to elastically stretch and contract along the radial direction.

The driving rod 2 comprises a driving part 21 and a pressing part 22, one end of the driving part 21 is provided with a driving head 211, the driving head 211 is abutted against the inner side wall of the vertebral body section 12, the pressing part 22 is positioned at one side of the sleeve body 1 and is connected with the other end of the driving part 21, the pressing part 22 is pressed to drive the driving part 21 to move in the sleeve body 1, and the driving part 21 moves in the sleeve body 1 to drive the driving head 211 to extrude the vertebral body section 12; the driving part 21 is provided with an elastic component 3 for driving the driving rod 2 to reset.

After the trachea is occluded or bitten, the vertebral body segment 12 of the sleeve body 1 is inserted into the trachea, then the pressing part 22 is pressed to drive the driving part 21 to move in the sleeve body 1, the driving part 21 moves in the sleeve body 1 to drive the driving head 211 to extrude the vertebral body segment 12, so that the side wall of the vertebral body segment 12 is elastically expanded along the radial direction, the occluded or bitten trachea is expanded and rounded, the treatment cost of a patient is reduced, and the life risk of the patient is reduced. After the trachea is expanded and rounded, the pressing is stopped, at the moment, the driving rod 2 is reset under the action of the elastic component 3, and the side wall of the vertebral body section 12 is elastically closed along the radial direction.

Optionally, the elastic assembly 3 includes a fixing block 31 and an elastic member 32, the fixing block 31 is disposed on the inner sidewall of the straight cylinder section 11, one end of the elastic member 32 abuts against the fixing block 31, and the other end of the elastic member 32 is fixedly connected to the driving portion 21. In this example, the elastic member 32 is preferably a compression spring. So, after the trachea struts and the rounding, stop pressing, loosen promptly and press the portion 22, compression spring is in compression state this moment, and compression spring provides elasticity and impels actuating lever 2 to resume initial condition to press next time. Can repeatedly press slowly, avoid compromising trachea cannula's integrality in the operation of strutting of trachea cannula.

As an example, three sets of elastic members 3 are provided in the driving portion 21 so that the initial state can be effectively restored after the trachea is expanded and rounded. Of course, two or four groups may be provided, which is not limited herein.

It should be noted that, when the pressing portion 22 is pressed to the bottom, the pressing portion 22 abuts against the end of the straight tube section 11 far away from the cone section 12, and at this time, the driving head 211 elastically expands the sidewall of the cone section 12 to the maximum extent along the radial direction. Thus, the opening effect is further improved, and meanwhile, the end part of the straight cylinder section 11 far away from the vertebral body section 12 also plays a limiting role, so that the driving head 211 is prevented from being separated from the vertebral body section 12.

According to some embodiments of the present invention, the gaps 122 are at least two and are evenly spaced in the circumferential direction of the vertebral body segment 12. Wherein, it can be understood that, set up gap 122 on the lateral wall of centrum section 12, set up opening 121 at the tip of centrum section 12 for the lateral wall of centrum section 12 can be strutted, and the circumference interval equipartition can strut, prop the circle to trachea cannula uniformly, guarantee that trachea cannula can be proofreaded the circle. Of course, in other examples, the end of the cone segment 12 may be not open and extend to the end of the cone segment 12 through the slit 122, that is, one end of the cone segment 12 is connected to the straight cylinder segment 11, and the other ends are spaced apart and disconnected from each other along the circumference of the cone segment 12.

According to a further embodiment of the present invention, the gap 122 segments the sidewall of the vertebral body segment 12 into petal-shaped snap fingers. In this manner, squeezing the vertebral body segment 12 by the driver head 211 causes the prongs to expand.

Optionally, the slots 122 are four and spaced circumferentially about the vertebral body segment 12. That is, the side wall is configured with four petal-shaped spring fingers so that the endotracheal tube can be evenly rounded. Of course, in other examples, the number of the slits 122 may be three or other numbers.

In addition, the sleeve body 1 in this example is preferably made of plastic material, so that the tracheal cannula is not easily damaged when the sleeve body 1 is inserted into the tracheal cannula. Meanwhile, the sleeve body 1 made of plastic material has certain elasticity and can be well matched with the tracheal cannula. In this example, the outer diameter of the straight cylinder section 11 can be made into different models according to actual situations, generally, the inner diameter of the tracheal cannula is 2.5mm-8mm, and the outer diameter of the straight cylinder section 11 is set to be slightly smaller than the inner diameter of the tracheal cannula, so as to improve the effects of opening and rounding.

In some examples, a connection port 111 is formed on the outer wall of the straight tube section 11, a vent 311 is formed on the fixing block 31, a vent channel 2111 is formed on the driving head 211, and the connection port 111, the vent 311, the vent channel 2111 and the opening 121 at the top end of the vertebral body section 12 together form a vent route. When the cuff body 1 is inserted into the trachea, oxygen can be introduced into the connection port 111 provided on the outer wall of the straight tube section 11, and the oxygen enters the lung of the patient along the air inlet 311, the air passage 2111 and the opening 121 at the tip of the vertebral body section 12.

In order to prevent oxygen from leaking out from the end of the straight cylinder section 11 far away from the vertebral body section 12, a sealing ring 4 is disposed at the end of the straight cylinder section 11 far away from the vertebral body section 12, and the driving part 21 passes through the sealing ring 4 and is connected with the driving head 211. The sealing ring 4 effectively prevents the escape of oxygen so that oxygen is delivered to the patient's lungs along the ventilation route.
