Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral support, in particular to an oral support expansion device. Background Art
[0002] In clinical practice, in order to keep the patient's mouth open, an opener is needed to expand the patient's mouth and support it. It is mainly used for patients in coma to help patients perform mouth breathing or mouth care. It can also be used for younger infants to facilitate the delivery of food or medicine into the body through the esophagus, as well as oral treatment and other operations. Commonly used opening tools include the butcher's mouth opener.
[0003] When the T-shaped mouth opener is actually used for expansion, the medical staff first inserts the two groups of support arms arranged at the end thereof into the patient's mouth, and then rotates the butterfly bolt to make the two groups of support arms move away from each other to achieve the purpose of opening the patient's mouth. In the process of inserting the support arms into the patient's mouth, it is difficult for the medical staff to control the insertion depth. In addition, due to the large difference in the distance between the lips and throats of children and adults, if the medical staff is not careful, it is easy to cause the ends of the support arms to hit the patient's throat, and in severe cases, the patient may be scratched. Therefore, there is a great safety hazard when using it. For this reason, we propose an oral support expansion device to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-4 , an oral support and expansion device, including an adjustment seat 1, and support arms 2 are symmetrically distributed on the sides of the adjustment seat 1. The connection method and working principle of the adjustment seat 1 and the support arm 2 are all existing technologies and will not be repeated here. A sleeve rod 3 is provided on the upper side of the adjustment seat 1, and an insertion rod 4 is inserted inside the sleeve rod 3. The side of the insertion rod 4 is connected to a limiting block 5, and the limiting block 5 is set as a return structure. The limiting block 5 set by the return structure can meet the opposite movement of the two groups of sleeve rods 3 to prevent them from limiting the sleeve rod 3 from expanding the patient's oral cavity.
[0023] Further, see Figure 2 It can be known that there are two groups of sleeve rods 3, and the two groups of sleeve rods 3 are connected by a fixing strip 7 on the side away from the limit block 5. The side of the fixing strip 7 is symmetrically provided with a mounting plate 8, and the inside of the mounting plate 8 is connected to the adjustment seat 1 by bolts. Through the setting of the fixing strip 7, the two groups of sleeve rods 3 can be connected, and with the setting of the mounting plate 8, the fixing strip 7 and the adjustment seat 1 can be disassembled and assembled. Therefore, after the adjustment seat 1 is damaged, the limit block 5 can be installed on a new group of adjustment seats 1.
[0024] Further, see Figure 2 It can be known that a buffer block 6 is distributed on the side of the limit block 5 away from the fixed bar 7, and the side of the buffer block 6 is arranged as an arc structure, and the buffer block 6 is also a circular structure. Through the setting of the buffer block 6, the patient's lips can be effectively prevented from being crushed, and because the end of the buffer block 6 is provided with an arc structure, it can prevent the lips from being indented.
[0025] Further, see Figure 3 and Figure 4 It can be known that Velcro 15 is glued to the inner side of the buffer block 6, and there are two groups of Velcro 15. The other group of Velcro 15 is glued to the side of the limit block 5. The two groups of Velcro 15 are respectively a velvet side and a hook side, so that the deformed buffer block 6 can be replaced in time.
[0026] Further, see Figure 3 and Figure 4 It can be known that a limit rod 9 is vertically inserted inside the sleeve rod 3, and a linkage block 10 is connected to the top of the limit rod 9, and limit grooves compatible with the limit rod 9 are equidistantly provided inside the insertion rod 4. When in use, the combined length of the sleeve rod 3 and the insertion rod 4 can be adjusted through the cooperation of the limit rod 9 and the linkage block 10 to achieve the change of the position of the limit block 5.
[0027] Further, see Figure 4 It can be known that the limit rod 9 is inserted into the inside of the support frame 11, and the lower side of the support frame 11 is fixedly connected to the sleeve rod 3, the upper side of the support frame 11 is connected to the spring 12, and the other end of the spring 12 is fixedly connected to the linkage block 10. Through the setting of the support frame 11, the spring 12 and the linkage block 10 can be easily connected, so that the linkage block 10 that stops being subjected to force can be automatically reset.
[0028] Further, see Figure 2 and Figure 4 It can be known that a slider 13 is connected to the side of the insertion rod 4, and a slide groove 14 is opened inside the sleeve rod 3 at a position corresponding to the slider 13. Through the mutual cooperation of the slider 13 and the slide groove 14, the pulled insertion rod 4 can be guided to ensure that the limit groove and the limit rod 9 are always on the same horizontal line, thereby facilitating the subsequent insertion of the limit rod 9 into the interior of the insertion rod 4.
[0029] Working principle: When the utility model is in use, the staff can first pull up the linkage block 10 according to the patient's body shape to drive the two groups of limit rods 9 to lift up. At this time, the limit rod 9 can be pulled out from the limit groove inside the insertion rod 4, and then the staff can push the limit block 5, thereby driving the two groups of insertion rods 4 to slide inside the two groups of sleeve rods 3. When the limit block 5 is pushed to a suitable position, the staff can stop pulling the linkage block 10. At this time, the limit rod 9 can be reset and moved down by the elastic force of the spring 12, and embedded in the corresponding limit groove inside the insertion rod 4, so as to realize the rapid limit of the insertion rod 4;
[0030] Then the staff can insert the two sets of support arms 2 into the patient's mouth, and make the buffer block 6 connected to the end of the limit block 5 contact the patient's lips, and then the staff can rotate the butterfly bolt on the adjustment seat 1, so that the two sets of sleeve rods 3 move in opposite directions to achieve expansion and support of the patient's mouth. At this time, the medical staff can take care of or treat the patient's oral cavity. After completion, the butterfly bolt can be rotated in the opposite direction to remove the two sets of sleeve rods 3 from the patient's oral cavity. Then the medical staff can disinfect and clean the removed device for reuse. The above is the entire working principle of the utility model.
[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
