Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cricothyroid membrane emergency puncture respiratory care component. Background Art

[0002] Cricothyroid membrane puncture is one of the emergency treatment methods used clinically for patients with airway obstruction and severe breathing difficulties. It can buy time for tracheotomy and is an important part of on-site first aid. At the same time, it has the advantages of being simple, fast, effective and easy to use. At present, this emergency nursing operation has some technical difficulties. The thickness of the cricothyroid membrane is difficult to determine, and the airway here is relatively narrow. If the nurse uses less force during the puncture operation, the needle will have difficulty penetrating the airway and will not play a role in respiratory ventilation. If more force is applied, the puncture needle will easily penetrate the entire airway, resulting in excessive insertion of the ventilation needle tube. The puncture needle is not inserted into the airway, and emergency ventilation cannot be given to the patient. Therefore, very experienced nurses are required to accurately puncture it in one go, otherwise it will add additional risks to the operation. This operation needs to be successful in one go as much as possible, and it must be fast, otherwise it will cause the patient to suffocate.

[0003] Currently, this technology uses a variety of devices, but it requires a puncture needle to be inserted into the throat for ventilation and emergency breathing. However, because it needs to be connected to the gas cylinder pipeline after the acupuncture, it is easy to cause the trachea to move when docking with the breathing equipment, and then involve the patient's wound, causing secondary damage to the patient.

The syringe 7 can be inserted into the patient's body in conjunction with the reserved needle 8. The outside of the air jet pot 1 is sleeved with a fixing rope 11, and the outside of the fixing rope 11 is provided with anti-slip grooves. The fixing rope 11 is convenient for fixing the air jet pot 1 to a connecting frame in the environment. The three-way valve 2 is assembled on the top of the air jet pot 1, the hose 3 is assembled on the outside of the three-way valve 2, the first connecting pipe 4 is assembled on the outside of the hose 3, and the other end is connected to the second connecting pipe 6, the second connecting pipe 6 is connected to the syringe 7, and the outside of the syringe 7 is slidably connected to the reserved needle 8. By using the syringe 7 as an active component, the change of air pressure can be buffered, and the reserved needle 8 can be prevented from being pulled out due to the patient's activities. The syringe 7 component plays a certain protective role.

[0026] The first connecting pipe 4 and the second connecting pipe 6 are externally slidably connected to a limiting mechanism 5, which includes a sliding frame 51, a trapezoidal block 54 and a spring 55. The sliding frame 51 can slide on the outside of the first connecting pipe 4 and drive the disc 52 to move, driving the spring 53 to move, and the sliding frame 51 is slidably arranged on the outside of the first connecting pipe 4. The inside of the sliding frame 51 is equipped with a disc 52, and a spring 53 is connected between the disc 52 and the hose 3. The spring 53 can drive the trapezoidal block 54 to move, and the trapezoidal block 54 can drive the spring 55 to move. The spring 55 is elastic and rebounds after the movement is completed.
