Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a tracheal tube fixer that is pushed forward by pressing. Background Art

[0002] Endotracheal intubation connected to a ventilator to support breathing is widely used in clinical practice as a means of rescuing critically ill patients. There are generally three ways of endotracheal intubation: one is nasal intubation, one is oral intubation, and one is to use tracheotomy to cut the front wall of the trachea in the neck and insert a cannula of appropriate size into the trachea through the incision. The patient can breathe directly through the tracheal cannula or connect to a ventilator.

[0003] Among them, the standard operation process of oral intubation is to first insert the cannula into the patient's mouth, then wear the fixator, and then fix the cannula on the fixator. The existing tracheal cannula fixing device usually uses the method of rotating the thumb screw to push the chuck to fix it. In the actual operation process, it is necessary to rotate the chuck several times to push it until the tracheal cannula is fixed. It is best to use both hands to push it, and it is relatively time-consuming. Although the time wasted is short, it may have a significant impact on the process of emergency treatment that races against time.

[0004] In order to solve the technical problems existing in the prior art, the inventor provides a push-pull endotracheal tube fixer. Utility Model Content

The chuck and the clamping groove cooperate to fix the tracheal tube, and the first and second teeth on the elastically hinged locking plate cooperate to lock the long tooth plate to ensure that its position does not change. However, when the chuck needs to be opened, the locking plate is opened upward, and under the action of the second reset spring, the long tooth plate and the chuck are automatically reset.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] As attached Figure 1 To Attachment Figure 3 As shown, Specific embodiment:

[0022] A push-pushing endotracheal tube holder comprises a base plate 1 which can be worn on the patient's mouth, a notch 2 corresponding to the position of the patient's mouth is provided on the base plate 1, a guide slot 3 is fixed on the base plate 1, a long tooth plate 4 is slidably connected in the guide slot 3, a chuck 5 is fixed at one end of the long tooth plate 4, a chuck 5 is provided at the end of the chuck 5 away from the long tooth plate 4, the chuck 5 and the chuck slot 6 cooperate to fix the endotracheal tube, the long tooth plate 4 is connected to a push-pushing mechanism and a locking mechanism, the push-pushing mechanism comprises a trapezoidal driven block 7 fixedly connected to the long tooth plate 4, the trapezoidal driven block 7 cooperates to connect a trapezoidal driving block 8, the trapezoidal driving block 8 is fixedly connected to the push rod 9, the trapezoidal driving block 8 is fixedly connected to the first return spring 10, the first return spring 10 is arranged in the spring seat 11 and is sleeved on the push rod 9; a guide baffle 12 is also fixed on the long tooth plate 4, the guide baffle 12 is slidably connected to the guide rod 13, the guide rod 13 is fixed in the U-shaped seat 14, and a second return spring 15 is arranged on the guide rod 13 on the side of the guide baffle 12 close to the chuck 5, the locking mechanism includes an elastically hinged locking plate 16, the locking plate 16 is provided with an oblique first latch tooth 17, and the long tooth plate 4 is provided with a second latch tooth 18 corresponding to the first latch tooth 17.

[0023] There are two pressing and pushing mechanisms, which are symmetrically arranged on the upper and lower sides of the long tooth plate 4. The push rods 9 of the two pressing and pushing mechanisms are fixedly connected to the L-shaped rod 19, the L-shaped rod 19 is connected to the pinching piece 20, the two pinching pieces 20 are close to each other, and the L-shaped rod 19 is slidably sleeved with the guide sleeve 21.

[0024] The working principle of the utility model is as follows: by pressing the pinching piece 20 with fingers, the two push rods 9 moving away from each other are driven to move, and the trapezoidal driven block 8 pushes the trapezoidal driven block 7 to move, thereby pushing the long tooth plate 4 and the chuck 5. During the movement of the long tooth plate 4, the second latch 18 pushes the first latch 17 upwards to cause the locking piece 16 to flip upwards, thereby ensuring that the chuck 5 moves toward the clamping groove 6. When the pinching piece 20 is stopped, the first latch 17 on the elastically hinged locking piece 16 will automatically snap into the second latch 18 to lock it, and due to the force of the second return spring 15, the long tooth plate 4 will be squeezed in the opposite direction, thereby ensuring the locking degree of the first latch 17 and the second latch 18. The pinching piece 20 is reset under the action of the first return spring 10 when one press is completed. When the locking piece 16 is pushed upward to release the lock, the long tooth plate 4 rebounds to the opposite direction under the action of the second return spring 15 and releases the fixation of the tracheal tube.

[0025] Specifically, the locking piece 16 is hinged on the bottom plate 1, and a torsion spring is arranged at the hinge position thereof. Under the action of the torsion spring, the locking piece 16 is pressed downward on the long tooth plate 4, and the first latching tooth 17 and the second latching tooth 18 are clamped, and the first latching tooth 17 and the second latching tooth 18 are both inclined in the opposite direction of the clamp 5. Due to the action of the second reset spring 15, the second latching tooth 18 will be tightly clamped behind the first latching tooth 17, and when the clamp 5 is pushed toward the clamping groove 6, the second latching tooth 18 will push the first latching tooth 17 to bounce upward, thereby releasing the locking restriction, that is, when the locking piece 16 is not pulled, the clamp 5 can only be pushed unidirectionally toward the clamping groove 6 and automatically locked.

[0026] The two ends of the base plate 1 are provided with strap connection holes 22, and the base plate 1 is fixed to the patient's neck by straps. Preferably, the straps are connected by Velcro. Velcro can adjust the tightness of the straps when they are tightened.

[0027] An anti-bite plate is provided at the inner edge of the clamping groove 6, and the inner side of the clamping head 5 is flush with the anti-bite plate. That is, the anti-bite plate and the clamping head extend into the patient's mouth for a certain distance to wrap the tracheal cannula therein to prevent the patient from biting the tracheal cannula.

[0028] Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
