Abstract
Description
Technical Field
[0001] This utility model relates to the field of tracheal fixation technology, and more specifically, to a tracheal cannula humidification and fixation device. Background Technology
[0002] Tracheotomy is a common clinical procedure for establishing an artificial airway. It 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] After surgery, the trachea needs to be fixed. However, existing tracheostomy tube fixation devices usually use Velcro to attach the tracheostomy tube fixation device to the patient's neck to prevent the fixation device from slipping off. At the same time, existing ventilation tube fixation devices only use clasps and straps, but the clasp structure is simple and the inner diameter cannot be changed. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a tracheal cannula humidification and fixation device.
[0005] This utility model is implemented as follows:
[0006] A tracheostomy cannula humidification and fixation device includes a fixation housing and a fixation mechanism. Connecting rings are installed on both outer sides of the fixation housing, and a connecting plate is installed on the outer side of one of the connecting rings. The fixation mechanism includes a mounting block, and a moving groove is provided on one inner side of the fixation housing. A placement groove is provided at the center of the inner side of the fixation housing, and the moving groove and the placement groove are interconnected. The mounting block is installed on the outer side of the fixation housing, and a clamping groove is provided inside the mounting block, which is interconnected with the placement groove. A first connecting rod is installed on one inner side of the clamping groove, and a first clamping block is installed at one end of the first connecting rod. A second connecting rod is installed inside the clamping groove on the side away from the first connecting rod. A first spring is provided on the outer side of the second connecting rod, and a second clamping block is installed at one end of the first spring. Both the first and second clamping blocks have grooves inside, and limit blocks are installed on both sides of the second clamping block. A pair of second fixing plates are installed on the outer side of the other connecting ring, and a winding roller is connected between the second fixing plates.
[0007] Furthermore, the mounting block has limiting grooves on both sides of the second clamping block, and the pair of limiting blocks are slidably mounted inside the limiting grooves.
[0008] The advantage of adopting the above-mentioned further solution is that, by providing a limiting groove, the movement of the second clamping block can be supported and limited.
[0009] Furthermore, a pair of first fixing plates are installed on both sides of the mounting block, and a sliding rod is connected between the pair of first fixing plates. An adjusting block is slidably installed on the outside of the sliding rod.
[0010] Furthermore, the mounting block has sliding grooves on both sides of the limiting groove, and one end of each pair of adjusting blocks passes through the sliding groove and extends into the interior of the limiting groove.
[0011] The beneficial effect of adopting the above-mentioned further solution is that, by providing a sliding groove, the position of the adjusting block can be adjusted according to the position of the second clamping block, which facilitates better engagement with the second clamping block.
[0012] Furthermore, the adjusting block has an installation groove on one side inside, and a second spring is connected to one side inside the installation groove. One end of the spring is connected to a locking block, and the limiting block has locking grooves on both sides inside, with the locking block and the locking groove engaging with each other.
[0013] The beneficial effect of adopting the above-mentioned further solution is that, by installing the locking block and the locking slot, the position of the limiting block can be fixed, thereby fixing and clamping the air tube with the second clamping block.
[0014] Furthermore, the connecting plate has a connecting groove inside, and an adjusting belt is connected inside the connecting groove. A gasket is slidably installed on the outside of the adjusting belt. One end of the adjusting belt is sleeved on the outside of the winding roller, and one end of the winding roller passes through one of the second fixing plates and is equipped with a worm gear.
[0015] Furthermore, a worm gear is mounted on the top of the retainer housing near the winding roller via a fixing member, and the worm gear meshes with a worm wheel. One end of the worm gear passes through the fixing member and is fitted with a rotating block.
[0016] The beneficial effect of adopting the above-mentioned further solution is that by installing a worm gear, the winding roller can adjust the length of the adjusting belt, and at the same time fix the position of the winding roller so that it will not rotate arbitrarily.
[0017] The beneficial effects of this utility model are as follows: The tracheostomy tube humidification fixator obtained by the above design, after surgery, moves the tracheostomy tube through the moving groove and placement groove into the clamping groove. Then, the second clamping block is squeezed to place the tracheostomy tube inside the first and second clamping blocks. After the tracheostomy tube is placed, the outer side of the tracheostomy tube is in contact with the first clamping block, and the second clamping block, under the elasticity of the first spring, is in contact with the other outer side of the tracheostomy tube. Then, the adjusting block is pulled to move inside the sliding groove. When the locking block on one side of the adjusting block engages with the locking block on the other side of the limiting block… After the slots interlock, the positions of the limiting block and the second clamping block are fixed, thereby clamping the trachea. When the tube diameter is different, the positions of the adjusting block and the clamping block can be adjusted. After adjustment, the adjusting strap is placed around the patient's neck. Then, the rotating block is rotated, which drives the worm gear to rotate. When the worm gear rotates, it drives the winding roller to rotate, winding up the excess adjusting strap. When the adjusting strap is tightly fitted to the neck, the rotation stops. The adjusting strap is made of pure cotton and has no elasticity, which increases the sweat absorption and comfort.
