Embodiment 1

[0049] Example 1, such as figure 1 , figure 2 , Figure 5 and Image 6 As shown, there is one vibration detection piece 7, and the first strain gauge 8 is selected as the sensing mechanism. An anti-jamming frame 10 is arranged around the periphery of the vibration detection piece 7, and the anti-jamming frame 10 is provided as a lateral overhang. The detection contacts of the vibration detection piece 7 701 protrudes downward from the anti-jamming frame 10; the X-Y-Z linear displacement mechanism includes a bottom X-Y-Z displacement system arranged between the bearing table 3 and the chassis 1 and a top X-Z displacement system arranged between the vibration detection piece 7 and the cantilever 5, X-Y-Z The overturning mechanism includes a bottom Y-axis overturning system arranged between the loading platform 3 and the chassis 1, the Y-axis direction is the longitudinal direction of the loading platform 3, the arm 4 is selected as the position to be punctured, and the radial...

Embodiment 2

[0064] Embodiment 2, as the optimization of embodiment 1, such as image 3 As shown, the vibration detection pieces 7 are two arranged along the lateral direction of the site to be punctured, and the two vibration detection pieces 7 are symmetrically arranged in the form of two adjacent detection contacts 701, as shown in image 3 As shown in , the distance between the two is greater than the diameter of the puncture needle 22, and the periphery of the two vibration detection pieces 7 is surrounded by an anti-interference frame 10. The head 701 protrudes downwards from the anti-interference frame 10; the X-Y-Z linear displacement mechanism includes a bottom X-Y-Z displacement system arranged between the bearing table 3 and the chassis 1 and a top X-Z displacement system arranged between the vibration detection piece 7 and the cantilever 5, The X-Y-Z turning mechanism includes a bottom Y-axis turning system arranged between the carrying platform 3 and the chassis 1. The Y-axis ...

Embodiment 3

[0074] Example 3, such as Figure 4 As shown, as a further optimization of embodiment 2, the position to be punctured can be selected from the arm 4 wrist, thigh or instep position, the vibration detection sheet 7 is two arranged along the lateral direction of the site to be punctured, and the two vibration detection sheets 7 are Two detection contacts 701 are arranged symmetrically adjacent to each other, the distance between them is greater than the diameter of the puncture needle 22, and the periphery of the two vibration detection pieces 7 is surrounded by an anti-jamming frame 10, and the lower end surface of each anti-jamming frame 10 is respectively attached with a second strain gauge 1001, such as Figure 5 and Image 6 As shown, the information output end of the second strain gauge 1001 is connected to the strain gauge 9, and the strain gauge 9 displays the waveform diagram of the feedback after the deformation of the second strain gauge 1001; The bottom X-Y-Z displ...

Abstract

The invention relates to an arterial puncture guide device and a use method thereof, and belongs to the technical field of medical equipment. The device comprises a bottom frame, a vertical column anda bearing platform, the vertical column and the bearing platform are fixed on the bottom frame, a vibration detector is fixed at the upper end of the vertical column by the aid of a cantilever and positioned above the bearing platform, a first strain gage is pasted on the surface of the vibration detector, an information output end of the first strain gage is connected with a strain meter, the vibration detector is horizontally overhung, the tail end of the vibration detector is a downward projection detection contact, the bearing platform bears the position to be punctured of a patient, thedetection contact contacts with the surface of the position to be punctured by the aid of a position adjusting system, the position adjusting system is arranged between the bearing platform and the bottom frame and / or the vibration detector and a cantilever, and the position adjusting system comprises an X-Y-Z linear displacement mechanism and an X-Y-Z overturning mechanism. According to the device, artery positions can be rapidly and accurately found, a lot of time and labor are saved, and dangerous conditions such as later needle deviation and purple stasis can be avoided as the device has high accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an arterial puncture guide device and a use method. Background technique [0002] General surgery requires anesthesia. Anesthesiologists usually look for arteries on the wrist, and then perform intubation, anesthesia, blood drawing, and pressure measurement. Special populations such as the elderly, obese adults, and children , due to weak pulse, thick fat, etc., it is very difficult to find the artery. The search time usually takes a few minutes or even longer, and sometimes it may not be found, which greatly affects the progress of the operation. There will also be dangers of congestion, swelling or even extremity necrosis due to inaccurate positions. Contents of the invention [0003] The present invention overcomes the shortcomings of the existing arterial puncture, and provides a guide device for arterial puncture and its use method. The guide device ...
