Embodiment 1
[0057] Such as figure 1 As shown, the present invention provides a medical measuring instrument, which at least includes a first scale value of 100 and a second scale value of 200 . The corresponding relationship between the second scale value 200 and the first scale value 100 is as follows:
[0058] The second scale value 200=[the first scale value 100×0.38696]+30.37+6. The accuracy of the corrected nose-earlobe-xiphoid-process distance formula (nose tip-earlobe-xiphoid-process distance*0.38696)+30.37+6cm has been widely confirmed in the prior art. According to the latest intubation length formula above, the operator needs to measure the nose tip-earlobe-xiphoid process distance and then convert it by himself. Since this calculation method is too cumbersome to convert, it will seriously affect the intubation efficiency and patient experience. Therefore, the present invention passes the first One scale value 100 is directly converted to the second scale value 200, and the co...
Embodiment 2
[0075] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.
[0076]The present invention also provides a medical measuring tool, which includes a plurality of segments 11 that can be sleeved on the object to be measured and nested with each other. One side of the segment 11 is at least partially covered with at least one adjustment portion 13 extending towards a first direction / a second direction away from the measured object. The end of the segment 11 along the sliding direction is provided with at least one stopper 12 capable of abutting against the adjusting portion 13 nested with the segment 11 to be in a compressed state. The limiting part 12 is connected to at least one end of the segment 11 in the circumferential direction so that the two ends of the segment 11 in the circumferential direction can be separated from each other and slide relative to each other under the force of the adjustment part 13 extending toward ...
Embodiment 3
[0078] This embodiment is a further improvement on Embodiments 1 and 2 and their combination, and the repeated content will not be repeated.
[0079] Since the nasogastric tube 30 is mostly used in the ICU ward, and the patient’s condition changes rapidly, and the purpose of the tube may change constantly, it is necessary for the medical clerk to quickly insert the tube to treat the patient in time. When the medical measuring instrument of the present invention is unfolded, the segment 11 may not be fully pushed or pulled, resulting in incomplete deployment, thereby making the measurement inaccurate. Based on the above problems, in this embodiment, an ejection mechanism 2 is provided in the adjustment part 13 to completely eject the segment after sliding a certain distance, so as to avoid the problem of inaccurate measurement due to incomplete push / pull of the segment 11 . In addition, since the medical measuring instrument of the present invention needs to slide in two direct...
