Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an improved tooth pad for gastroscopy. Background Art

[0002] The existing dental pads for gastroscopy under general anesthesia for endotracheal intubation only provide a channel for placing the endotracheal tube and a channel for gastroscopy, but do not provide a device for fixing the endotracheal tube. Therefore, the endotracheal tube needs to be fixed to the patient's facial skin with medical tape. The sticking of medical tape can easily cause skin damage to the patient and prolong the treatment cycle. At the same time, in order to ensure better exposure of the intragastric space, the left side lying position is routinely used for gastroscopy. The patient's saliva secretions flow out from the corners of the mouth and soak the medical tape, causing the medical tape to lose its stickiness and thus unable to play the role of fixing the endotracheal tube, which may lead to unplanned extubation of the endotracheal tube and endanger the patient's life. Secondly, affected by the special body position requirements of gastroscopy, when the endotracheal tube needs to be removed at the end of the gastroscopy, the patient will be pressed by the tape on the left side of the face or overlapped by the dental pad, and the fixed medical tape cannot be separated in time, thereby affecting the removal of the endotracheal tube and increasing the risk of adverse respiratory complications such as pharyngeal injury and airway obstruction. For example, the document with Chinese patent publication number CN107847703A discloses a fixing product for an airway tube holder. This product is a tube fixing device currently used in some hospitals. The method of use is to fix the panel to the patient's mouth, and then use the locking structure of the screw and nut to fix the tube passing through the patient's mouth. However, the problem with this patented technology is that it has a clear installation direction. During installation, the side with the notch must correspond to the patient's mouth, making the device inconvenient to install, especially for some surgeries that require emergency intubation. It is easy to make installation errors or delays in installation within a tight time. According to nursing requirements, medical staff need to regularly observe the patient's tracheal intubation. Therefore, medical staff need to regularly disassemble the fixing device to observe the situation, and the fixing device of the prior art such as the above-mentioned is not convenient for quick installation and disassembly.

[0003] In addition, the dental pads in the prior art usually consist of some small parts. Since the patient will keep his mouth open to a certain extent after intubation, if the small parts fall off at this time, they may fall into the patient's mouth and accidentally enter the airway, affecting the patient's safety and experience. Summary of the invention

The elastic sheet is a strip-shaped rubber body, which passes through the roller introduction block to sleeve the hook and is installed on the inner side of the roller introduction block.

[0007] Furthermore, the tooth gasket body is in an arc shape, and the curvature of the tooth gasket body matches the curvature of the mouth.

[0008] Furthermore, an introduction block gap is left between the roller introduction block and the C-shaped elastic clamping arm, and both ends of the elastic sheet pass through the introduction block gap and are connected to the hook. The C-shaped elastic clamping arm, the roller introduction block and the elastic sheet constitute an elastic clamping area for clamping the tracheal tube.

[0009] Furthermore, the tooth gasket body, the anti-bite pad body, the hook and the C-shaped elastic clamping arm are made of medical polypropylene plastic.

A hook 8 is fixedly arranged on the outer side of the C-shaped elastic clamping arm 6. An elastic sheet 9 for clamping the endotracheal tube is fixedly sleeved on the hook 8. The elastic sheet 9 is a strip-shaped rubber body, which passes through the roller introduction block 7 to sleeve the hook 8 and is installed on the inner side of the roller introduction block 7; buckles 10 for fixing the tooth pad body 1 are provided at both ends of the tooth pad body 1, and the buckle 10 is sleeved with an elastic bandage 11 for fixing the tooth pad body 1 and the patient's mouth.

[0029] The tooth gasket body 1 is a thin sheet made of flexible material and has an overall arc shape. The curvature of the tooth gasket body 1 matches the curvature of the mouth. An introduction block gap 12 is left between the roller introduction block 7 and the C-type elastic clamping arm 6. Both ends of the roller elastic sheet 9 pass through the introduction block gap 12 and are connected to the hook 8. The C-type elastic clamping arm 6, the roller introduction block 7, and the elastic sheet 9 constitute an elastic clamping area for clamping the endotracheal tube. The tooth gasket body 1, the anti-bite pad body 2, the hook 8 and the C-type elastic clamping arm 6 are made of medical polypropylene plastic. The tooth gasket body 1, the anti-bite pad body 2, the hook 8 and the C-type elastic clamping arm 6 are integrally injection molded.

[0031] The tracheal tube fixing device 5 adopts a C-shaped elastic clamping arm, which can meet the fixing requirements of 7.0-8.0 adult tracheal tubes; the designed rubber roller introduction block 7 and the C-shaped elastic clamping arm 6 cooperate with each other to perform multiple tube tightening and fixing operations, better fix the tube, and avoid tube displacement; the improved design of the rubber roller introduction block 7 allows the operator to quickly fix the tracheal tube without the need for secondary fixation, and can simultaneously achieve rapid separation of the tracheal tube and the tracheal tube fixing device, greatly simplifying the operation of removing the tracheal tube, which can facilitate the operation of medical staff and ensure the safety of patients, and has the value of wide promotion.

[0032] The working principle of the utility model is as follows: the tooth pad body 1 of the improved tooth pad for gastroscopy is designed to be made of an integrated molded structure and is a symmetrical structure. The tooth pad is an arc-shaped structure with symmetrical hollow openings at both ends. The inner side of the curved surface of the tooth pad body 1 is connected with a hollow anti-bite pad body 2 which is perpendicular to the tooth pad body 1.
