[0033] The operation steps of cricothyroid puncture are as follows:

[0034] Preoperative preparation

[0035] Instrument preparation: Prepare a cricothyroid puncture needle or a thick needle, a syringe, an oxygen connection device (such as a T-tube, an oxygen inhalation tube, etc.), disinfection supplies, sterile towels, etc.

[0036] Patient preparation: The patient takes a supine position, with the shoulder and back padded up, the head tilted back, and the neck fully exposed. If the patient cannot tolerate the supine position, a semi-sitting position can be taken. If conditions permit, an assistant can stand on the left side of the patient to fix the shoulders, and another assistant can stand at the head end of the patient to fix the head.

[0037] Determine the puncture point: The operator touches the thyroid cartilage and the cricoid cartilage with fingers, and the depression between the two is the cricothyroid membrane. Usually, the midpoint of the upper edge or the midpoint of the lower edge of the cricothyroid membrane is selected as the puncture point.

[0038] Disinfection and draping: Routinely disinfect the skin in the cricothyroid membrane area, with the puncture point as the center and a diameter of about 15 cm. If the situation is urgent, sterile towels may not be draped.

[0039] Local anesthesia: If time and the patient's condition permit, 1% procaine or lidocaine containing a small amount of adrenaline can be used for subcutaneous infiltration anesthesia in the anterior cervical operative area; if the situation is urgent or the patient is already comatose, anesthesia may not be used.

[0040] Puncture operation: The operator fixes both sides of the cricoid cartilage with the left thumb and index finger, and holds the puncture needle or thick needle with the right hand, and vertically inserts it into the membranous part between the cricoid cartilage and the thyroid cartilage.

[0041] Confirm successful puncture: When there is a sense of falling through and air can be aspirated back, it indicates that the puncture needle has entered the trachea. If a syringe is used, air can be aspirated first to confirm the position.

[0042] Connection and fixation: If ventilation is required, connect the puncture needle to a resuscitation balloon, a ventilator, an oxygen connection device, etc. Fix the puncture needle properly with tape or the like to prevent it from slipping out or shifting.

[0043] Postoperative monitoring: Closely observe the patient's ventilation status and changes in vital signs, such as respiratory rate, rhythm, depth, blood oxygen saturation, etc., to ensure that dyspnea is relieved.

[0044] Example 1:

[0045] As Figures 1-5 shown, the present invention. Specifically, a cricothyroid membrane puncture-assisted breathing device with an auxiliary positioning structure includes a puncture assembly 200, and the puncture assembly 200 includes a puncture needle 202 connected to a needle head 201;

[0046] A breathing assistance assembly, which is detachably connected to the needle head 201;

[0047] An auxiliary positioning structure 100, which is coupled to the needle head 201. The auxiliary positioning structure 100 includes a guiding sleeve 101, a neck fixing band 102 connected to the outside of the guiding sleeve 101, and the puncture needle 202 is movably arranged in the guiding channel 1011 of the guiding sleeve 101.

[0048] The neck fixing band 102 is made of an elastic material and can be adaptively adjusted according to the different thicknesses of the patient's neck. The neck fixing band 102 is made of an elastic material and can be adaptively adjusted according to the different thicknesses of the patient's neck. The positioning marking points are accurately designed through precise human anatomical measurements and precisely correspond to the position of the cricothyroid membrane. Although the cricothyroid membrane is a relatively superficial and relatively fixed structure in the neck and is easy to locate, individual differences still affect the puncture accuracy. The design of the neck fixing band 102 fully considers the anatomical landmarks around the cricothyroid membrane, such as the thyroid notch, cricoid cartilage, etc., to make the positioning more accurate, and medical staff can quickly determine the puncture position.

[0049] A plurality of positioning marking points are provided on the neck fixing band 102.

[0050] A first holding part 104 is connected to the tube body of the guiding sleeve 101.

[0051] The neck fixing band 102 is connected to the outside of the guiding sleeve 101 through a connecting structure 103, and the connecting structure 103 includes;

[0052] A fixed connecting head 1031, which is fixedly connected to the neck fixing band 102. An annular cavity 1032 is formed inside the fixed connecting head 1031;

[0053] A movable connecting head 1031, which is rotatably arranged in the annular cavity 1032. A connecting column 1031 is connected to the center of the bottom of the movable connecting head 1031, and the connecting column 1031 is fixedly connected to the outer wall of the guiding sleeve 101. Due to the existence of the connecting structure 103, the guiding sleeve 101 can rotate relative to the neck fixing band 102, so as to ensure that the guiding sleeve 101 is aligned with the positioning mark point. The movable connecting head 1031 is fixedly connected to the guiding sleeve 101 through the connecting column 1031. The fixed connecting head 1031 is fixedly connected to the neck fixing band 102, while the movable connecting head 1031 is rotatably connected inside the fixed connecting head 1031.

[0054] The puncture assembly 200 further includes a connecting pipe head 203 connected to the tail of the needle 201, two arc-shaped clamping blocks 205 and a second holding part 204 connected to the front end of the needle 201. A positioning clamping block 1012 is arranged at the tail of the guiding sleeve 101. The two arc-shaped clamping blocks 205 are arranged at intervals, and the positioning clamping block 1012 can be clamped between the two arc-shaped clamping blocks 205. When the puncture needle 202 pierces the cricothyroid membrane, the arc-shaped clamping blocks 205 at the tail of the guiding sleeve 101 are clamped between the two arc-shaped clamping blocks 205 of the second holding part 204 to achieve fixation.

[0055] The second holding part 204 is in the shape of a thin sheet, and the needle 201 is penetrated through the second holding part 204.

[0056] The breathing assistance assembly includes an airbag connecting head 401 and an airbag 402. One end of the airbag connecting head 401 is detachably connected to the needle 201, and the other end is connected to the airbag 402. An oxygen delivery connecting pipe is arranged on the airbag 402.

[0057] It further includes a needle cap 300, which can be covered on the guiding sleeve 101 and block the puncture needle 202.

[0058] Puncture assembly: The cricothyroid membrane tissue is relatively thin. When puncturing, it is necessary to accurately control the force and angle to avoid damaging the surrounding tissues. While ensuring a smooth puncture, the damage to important structures such as surrounding blood vessels and nerves is minimized to the greatest extent. The connecting pipe is tightly connected to the puncture needle, and a one-way valve is arranged on the connecting pipe to prevent gas backflow.

[0059] Respiratory assistance component: The respiratory assistance component includes a small breathing balloon and an oxygen delivery tube. The breathing balloon can be manually squeezed to provide gas at a certain pressure for the patient to maintain the patient's breathing. The oxygen delivery tube can be connected to an external oxygen source to provide sufficient oxygen for the patient. After successful cricothyroid puncture to establish an airway, timely and effective respiratory support is crucial, and this component can quickly provide the necessary gas supply for the patient.

[0060] Principle and adaptability of cricothyroid puncture: The cricothyroid membrane is located between the thyroid cartilage and the cricoid cartilage and is an ideal puncture site for establishing an artificial airway in case of upper airway obstruction. The design of this device strictly follows the anatomical characteristics of the cricothyroid membrane. The design of the neck fixing band and the puncture needle ensures that important blood vessels and nerves in the neck can be accurately avoided during operation, improving the safety of puncture. In addition, for patients of different ages and body types, there will be certain differences in the position of the cricothyroid membrane and the surrounding anatomical structures. The sizes and specifications of the neck fixing band and the puncture needle have multiple adjustable or optional schemes to meet diverse clinical needs.

[0062] Positioning operation: Gently place the neck fixing band on the patient's neck, adjust the size of the neck fixing band according to the thickness of the patient's neck, so that the positioning mark points accurately correspond to the position of the cricothyroid membrane. During the adjustment process, pay attention to gentle movements to avoid unnecessary damage to the patient. At the same time, reconfirm the corresponding relationship between the neck fixing band and the anatomical landmarks around the cricothyroid membrane to ensure accurate positioning.

[0063] Puncture operation: Medical staff strictly follow the principle of aseptic operation, hold the puncture needle, maintain a stable posture, and accurately insert the puncture needle into the cricothyroid membrane at an appropriate angle and force according to the indication of the positioning mark points. Specifically, fix the neck fixing band 102 on the patient's neck, and rotate the guiding sleeve 101 so that the front end of the guiding sleeve 101 is aligned with the positioning mark points. One finger of a medical staff's hand pinches the first holding part 104 and keeps it still, while the other hand pinches the second holding part 204 to make the puncture needle 202 penetrate out of the guiding sleeve 101 and insert. During the puncture process, closely observe the changes in the patient's vital signs. Once an abnormality occurs, immediately stop the operation and take corresponding measures. The puncture angle needs to be adjusted according to the specific situation of the patient, such as the fatness or thinness of the neck and the actual position of the cricothyroid membrane, to ensure safe and effective puncture.

[0064] Connection and respiratory support: After successful puncture, quickly connect the puncture needle to the respiratory assistance component through a connecting tube to ensure a tight connection without air leakage. Subsequently, according to the actual situation of the patient, rhythmically squeeze the breathing balloon to provide respiratory support for the patient, and connect the oxygen delivery tube as needed to deliver oxygen to the patient. During the operation process, closely monitor the pressure of the breathing balloon and the patient's respiratory recovery situation, and timely adjust the operation parameters to ensure that the patient receives the best respiratory support.
