Description

technical field [0001] The invention belongs to the technical field of puncture fixation in the department of anesthesiology, and specifically refers to a gravity-type self-adjusting fixation device for puncture in the department of anesthesiology using non-Newtonian fluid. Background technique [0002] Before performing surgery on the patient's arm, it is necessary to puncture the patient's arm with an anesthetic needle and inject anesthesia to temporarily lose sensation in the patient's arm to achieve painlessness, thereby providing conditions for surgical treatment. Most of the puncture process lacks the function of firmly fixing the anesthesia needle body. Often, the medical staff directly punctures the patient's arm with the anesthesia needle. The puncture stability is reduced, the puncture depth and angle are difficult to control, and the probability of inaccurate puncture positions is greatly increased, resulting in large errors in the insertion of anesthesia needles,...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a gravity-type self-adjusting anesthesia puncture fixation device using non-Newtonian fluid. Most of the existing arm fixation mechanisms need the help of motors, sensors and other devices to achieve accurate positioning. For the problem of arm fixation, this solution creatively uses the patient's own gravitational potential energy as the power source of the gravity self-adjusting control component 2200 and the gravity self-adjusting fixation component 2300, which can automatically fix the patient's arm when the patient is lying down , after the patient gets up and leaves, the arm can be released automatically. This solution achieves the technical effect of automatically fixing the arm when the patient is lying down and automatically releasing the arm when the patient is getting up without the help of motors and sensors. , so that the patient can control the operation of fixing the arm and releasing the arm; this scheme cleverly introduces the non-Newtonian fluid inflatable fixing component 2400, and by setting the inflatable elastic airbag 2403, the gravity self-adjusting fixing mechanism 2000 and the arm are added. The contact area between them solves the problem of ensuring the patient's comfort and firmly fixing the patient's arm which is difficult to solve in the existing prior art; this scheme utilizes the non-Newtonian fluid 2405 which will Temporarily becoming a solid with extremely high hardness. Before the puncture, use the contact capsule 2404 containing the non-Newtonian fluid 2405 to fit and wrap the part of the arm that needs to be fixed. When the patient moves the arm quickly due to pain, The non-Newtonian fluid 2405 hardens instantly under the action of strong pressure, hindering the movement of the arm, and further strengthening the fixing effect on the arm, which solves the large damage to the nerve and muscle tissue caused by the rapid movement of the arm by the patient. The problem of injury eliminates potential safety hazards. At the same time, since the non-Newtonian fluid 2405 is in a fluid state when the pressure is low, the patient feels more comfortable; Compared with the way of adjusting the angle through gear transmission and other structures in the prior art, the angle adjustment method adopted in this solution is more accurate. After the adjustment is completed, the puncture angle is fixed by the electromagnet 3001, which solves the problem caused by human hand shaking. The problem that the puncture angle is difficult to control; in this solution, by setting the puncture fixing component 4200, a sufficient amount of baking soda and a sufficient amount of vinegar can react in the inflatable reaction cylinder 4203 to generate a sufficient amount of carbon dioxide, which is enough to expand the puncture fixing capsule 4209 , so as to block the gap between the puncture fixing plate 4204 and the puncture needle body 4206, which is convenient for fixing different types of puncture needle bodies 4206. At the same time, when the puncture fixing capsule 4209 expands, the fixing The protrusion 4210 will be firmly engaged with the fixing groove 4205 on the puncture fixing plate 4204, which reduces the deviation of the puncture needle body 4206 during the puncture process and enhances the fixing effect
