Description

Technical Field

[0001] The utility model belongs to the field of medical supplies, and in particular relates to an incisor distance measuring ruler. Background Art

[0002] Difficulty in opening the mouth, also known as limited mouth opening, refers to the symptom of opening the mouth smaller than normal or being unable to open the mouth at all. It is usually because the patient's head and neck chin-mandibular joint and masseter muscle undergo degeneration and fibrosis due to the long-term accumulation of radiation during the treatment process, and eventually the chin-mandibular joint functional activity disorder occurs. The degree of difficulty in opening the mouth can be divided into 4 levels according to the degree of limited mouth opening: Level I is limited mouth opening, with an incisor distance of 2.0 to 3.0 cm; Level II is difficulty in eating, with an incisor distance of 1.1 to 2.0 cm; Level III is difficulty in eating soft food, with an incisor distance of 0.5 to 1.0 cm; Level IV is unable to eat, with an incisor distance of <0.5 cm; therefore, it is necessary to measure the incisor distance of patients with difficulty in opening the mouth. At present, nurses use a soft ruler to measure the incisor distance of the above patients, but it is difficult to place the zero scale of the soft ruler on the biting surface of the teeth, resulting in a certain reading error; at the same time, it is also difficult to provide a certain support to the patient's oral cavity, which will bring a certain sense of fatigue to the patient to be measured. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0024] Please also read Figures 1 to 4 Now, the incisor distance measuring ruler provided in the embodiment of the utility model is described.

[0025] like Figures 1 to 4 As shown, the incisor distance measuring ruler of the embodiment of the utility model includes a ruler body 100, a first measuring block 200 and a second measuring block 300. The ruler body 100 is marked with a length scale 110. The first measuring block 200 is fixedly connected to one end of the ruler body 100. The first measuring block 200 protrudes outward relative to the ruler body 100 to form a first supporting portion 220. The second measuring block 300 is slidably sleeved on the ruler body 100. The second measuring block 300 is provided with a second supporting portion 320 protruding outward from the second measuring block 300.

[0026] The first support portion 220 protrudes outward relative to the ruler body 100, and the second support portion 320 protrudes outward from the second measuring block 300. Since measuring the incisor distance is to measure the distance between the patient's upper and lower incisors, it is necessary to measure in front of the patient's mouth. The protruding structure of the first support portion 220 and the second support portion 320 can conveniently rest against the top of the patient's lower teeth and the bottom of the upper teeth during measurement, thereby providing support and a fulcrum for the patient's teeth.

[0027] Exemplarily, a first groove 221 for accommodating teeth is provided on the first support portion 220, and a second groove 321 for accommodating teeth is provided on the second support portion 320. The first groove 221 and the second groove 321 are used to accommodate the upper and lower teeth, so as to facilitate the fixation of the teeth during measurement. When measuring, the teeth are accommodated in the first groove 221 and the second groove 321 and are not easily displaced to cause measurement deviation.

[0028] Exemplarily, a first handle 210 for holding and fixing the first support part 220 is fixedly connected to the first support part 220, and a second handle 310 for holding and sliding the second support part 320 is fixedly connected to the second support part 320. When using the incisor distance measuring ruler, medical staff need to grasp the first measuring block 200 and the second measuring block 300. The first handle 210 extends from the first measuring block 200, which is convenient for medical staff to hold the first handle 210 to fix the position of the first measuring block 200. The second handle 310 extends from the second measuring block 300, which is convenient for medical staff to hold the second handle 310 to slide the position of the second measuring block 300, making the measurement operation simpler and more convenient.

[0029] Exemplarily, a sleeve hole 330 is provided on the second measuring block 300, and the second measuring block 300 is sleeved on the ruler body 100 so that the ruler body 100 passes through the sleeve hole 330, and the sleeve hole 330 has the same cross-sectional size and shape as the ruler body 100, so that the second measuring block 300 can slide along the ruler body 100, and the sleeve hole 330 has the same cross-sectional size and shape as the ruler body 100, so that when the second measuring block 300 moves on the ruler body 100, it will not tilt forward or backward to affect the accuracy of the final measurement reading.

[0030] Exemplarily, a slot 120 is provided on the other side of the ruler body 100 marked with the length scale 110, and a snap-in block (not shown in the figure) snap-in to the slot 120 is provided on the inner side of the second measuring block 300. The snap-in block snaps into the slot 120 to fix the position of the second measuring block 300.

[0031] Exemplarily, a disposable rubber cover is provided on the first measuring block 200 and the second measuring block 300 to prevent the patient's teeth from damaging the first measuring block 200 and the second measuring block 300, and to prevent the patient's saliva from contaminating the incisor distance measuring ruler during use. After the measurement is completed, the rubber cover is discarded as medical waste, so that the incisor distance measuring ruler can be reused after cleaning and disinfection, thereby reducing the cost of use.

[0032] Compared with the prior art, the incisor distance measuring ruler provided by the utility model has the following beneficial effects:

[0033] The utility model can accurately measure the patient's incisor distance, and can reduce the fatigue of the patient's teeth and mouth during measurement. The patient with limited mouth opening has degenerative changes and fibrosis in the temporomandibular joints and masseter muscles of the head and neck, and has functional activity disorders of the temporomandibular joints. Medical staff need to measure the incisor distance to determine the degree of the patient's limited mouth opening. When in use, the medical staff first places the first measuring block 200 on the patient's lower teeth, and uses the first supporting part 220 protruding outwardly relative to the ruler body 100 to press against the lower teeth, and then slides the second measuring block 300, and uses the second supporting part 320 protruding outwardly from the second measuring block 300 to press against the upper teeth, and slides the second measuring block 300 along the ruler body 100 to the patient's maximum mouth opening. At this time, the length scale 110 on the ruler body 100 is read, and the patient's incisor distance is measured to confirm the patient's limited mouth opening degree. According to the patient's mouth shape, tooth shape and degree of masseter muscle degeneration, the medical staff can use the ruler body 100 to measure the patient's incisor distance. The ruler body 100 can also be turned upside down according to actual measurement needs, and the first support part 220 on the first measuring block 200 is used to press against the patient's upper teeth, and then the second measuring block 300 is slid, and the second support part 320 is used to press against the lower teeth, so as to measure the patient's incisor distance. Due to the supporting effect of the first support part 220 and the second support part 320, the upper and lower teeth of the patient can be stably pressed against to provide support for the patient's teeth. The patient does not need to exert much effort when keeping his mouth open, which can reduce the fatigue of the patient's teeth and mouth when measuring the incisor distance. In addition, the first support part 220 and the second support part 320 support the patient's teeth, which is convenient for reading in a stable state. In this way, the measured incisor distance will be more accurate. The medical staff only needs to slide the second measuring block 300 to the maximum opening degree of the patient to read the value. The entire incisor distance measuring ruler has a simple structure and is also convenient for medical staff to operate.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
