Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal intubation teeth pad which is convenient for adjusting the aperture. Background Art

[0002] Tracheal intubation is an important measure to rescue critically ill patients. Keeping the airway open is the key to successfully rescuing critically ill patients. In order to prevent the patient from biting the tracheal tube flat, a tooth pad structure is generally set at the position of the teeth. Existing tooth pads generally adopt two structures. One is to directly set a thickened structure at the corresponding position of the tracheal tube, and the other is a component structure composed of multiple parts.

[0003] Among them, the endotracheal tube bite pad that is easy to adjust the position disclosed in application number CN202020405313.6 is also an increasingly mature technology. The bite pad body includes an integrally formed first conical sleeve and a second conical sleeve. The first conical sleeve and the second conical sleeve are provided with a plug hole for the endotracheal tube to pass through. The outer side of the second conical sleeve is covered with a soft sleeve, and the inner side of the soft sleeve is a tapered hole structure that matches the outer side of the second conical sleeve. The outer side of the first conical sleeve is connected with a locking sleeve by a thread, and a limiting plate is provided on the right side of the locking sleeve. The left end face of the soft sleeve abuts on the limiting plate. A limiting ring is provided on the right side of the second conical sleeve, and the right end face of the soft sleeve abuts on the limiting ring. The utility model has a novel structure, can conveniently complete the adjustment of the position of the bite pad, and the whole is completed by only three structural parts, easy to manufacture, and high reliability.

[0004] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0005] When wearing this type of tracheal intubation mouth guard, the patient's mouth is opened too small, which makes subsequent intubation operations inconvenient, and a single-sized sleeve is difficult to meet actual usage requirements. Utility Model Content

[0006] The utility model aims to provide a tracheal tube mouthpiece with an easy-to-adjust aperture, so as to solve the problem in the above-mentioned background technology that a single sleeve body is difficult to meet the use requirements.

[0008] Among them, the adjusting device includes a limit plate arranged on the back of the baffle cover, a lower support plate sliding inside the limit plate, a threaded rod arranged at the middle bottom end of the lower support plate, a threaded hole arranged at the bottom of the baffle cover, the threaded rod is located inside the threaded hole, a limit groove is arranged at one end of the lower support plate close to the baffle cover, a lower tooth pad is arranged at the bottom of the lower support plate, and a hinged seat is arranged near the bottom end of the side wall at one end of the lower tooth pad away from the baffle cover, the hinged seat has an internal hinged support rod and is fixedly connected to a tongue depressor at one end.

[0009] In this embodiment, by rotating the threaded rod, the threaded rod rotates inside the threaded hole, and then the threaded rod drives the limiting groove of the lower support plate to slide up and down along the inside of the limiting plate, and the limiting plate drives the lower tooth pad to adjust up and down, which is convenient for medical staff to operate.

[0010] In one embodiment of the utility model, an upper support plate is provided on the back of the baffle at the top of the conduit, an upper tooth pad is provided on the top of the upper support plate, and L-shaped grooves are respectively provided at the bottom and top of the lower support plate and the upper support plate.

[0011] In this solution, the upper teeth of the patient are supported by an upper support plate and an upper tooth pad, and the L-shaped groove facilitates the installation of the support plate.

[0012] In one implementation of the utility model, food-grade silicone pads are provided inside the upper tooth pad and the lower tooth pad, and the upper tooth pad and the lower tooth pad are respectively installed inside the L-shaped groove.

[0013] In this solution, the food-grade silicone pad can act as a cushion, effectively reducing the friction of the dental pad on the oral soft tissue, and the L-shaped groove allows the patient to easily and firmly fix the dental pad in the desired position.

[0014] In one embodiment of the utility model, installation grooves are provided on both sides of the shield, a shaft rod is vertically arranged inside the installation groove, a first strap and a second strap are respectively arranged outside the shaft rod, and the ends of the straps close to the installation grooves are made of elastic bands.

[0015] In this solution, the first strap and the second strap facilitate fixing the patient's head, and the elastic band can adjust the tightness of the strap according to the patient's specific situation and comfort requirements.

[0016] In an implementation manner of the utility model, two rows of buckle blocks are arranged on the front side of the first binding strap, and multiple rows of concealed buckles are arranged on the back side of the second binding strap.

[0017] In this solution, by cooperating with the buckle blocks and the concealed buckles, different buckle blocks or concealed buckles can be selected according to the needs of patients with different head circumferences to adjust the fit and comfort of the shield.

[0018] In one embodiment of the utility model, a hose is provided inside the catheter, a sputum suction ball and an air bag are provided at both ends of the hose, and a plurality of through holes are provided on the surface of the sputum suction ball.

[0019] In this solution, negative pressure is generated by pressing the airbag, so that the suction ball in the patient's throat absorbs saliva or sputum, which is sucked into the airbag through a hose, making it easier to process the saliva or sputum in the patient's mouth.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The intubation tube is inserted into the patient's lung trachea through the catheter, and the upper tooth pad and the lower tooth pad are placed in the patient's mouth. The threaded rod is rotated so that the threaded rod rotates inside the threaded hole, and then the threaded rod drives the limiting groove of the lower support plate to slide up and down along the inside of the limiting plate, and the limiting plate drives the lower tooth pad to adjust up and down, which is convenient for medical staff to operate and increases the comfort of the patient. The tongue depressor is used by the patient to press and limit the tongue to avoid the stimulation of the tongue by the intubation tube. The food-grade silicone pad can play a padding role, effectively reducing the friction of the tooth pad on the oral soft tissue, and avoiding the patient's gum friction injury when biting. The buckle block of the first strap is matched with the hidden buckle of the second strap, and different buckle blocks or hidden buckles can be selected according to the needs of patients with different head circumferences to adjust the fit and comfort of the shield. When there is saliva or sputum in the patient's mouth, negative pressure is generated by pressing the air bag, so that the sputum suction ball in the patient's throat absorbs the saliva or sputum, and the sputum is sucked into the air bag through a hose, which is convenient for processing the saliva or sputum in the patient's mouth.
