Analysis on the market competition of cardiopulmonary resuscitation apparatus

Cardiopulmonary resuscitation (CPR) devices were originally designed to increase blood flow to the heart and brain of patients with cardiac arrest and to bridge the gap for subsequent defibrillation, intravenous administration, and vascular reconstruction.

Unfortunately, there is very little blood flow to the heart and brain with traditional hands-only CPR, so even though hands-only CPR has been standard for 50 years, most cardiac arrests still end in death. Studies have shown that the production of cardiopulmonary resuscitation (CPR) devices provides only 10 to 20 percent of the blood flow to the heart and 20 to 30 percent to the brain under normal physiological conditions.

The medical community's urgent demand for high-quality cardiopulmonary resuscitation (CPR) technology, coupled with the inherent limitations of traditional hands-only CPR, has spurred a rush for new techniques that increase circulating blood volume. The mechanical equipment development of cardiopulmonary resuscitation has also gone through a certain course.

Of course, whether hands-only CPR or mechanical CPR, zUI's ultimate goal is to increase blood flow to the heart and brain in patients with cardiac arrest, prevent the heart and brain from going into irreversible death, and gradually repair the functioning of the heart and brain organs.

Mechanical CPR is CPR with a mechanical device, often called a cardiopulmonary resuscitation machine, cardiopulmonary resuscitation apparatus.

What is the intended use of cardiopulmonary resuscitation apparatus?

The resuscitation methods of artificial chest compressions and artificial mouth - to - mouth blowing should be replaced by emergency rescue for patients with cardiac arrest and respiratory arrest.

8. What are the indications and contraindications for the production of CARDIopulmonary resuscitation?

Indications: to the cardiac arrest and respiratory arrest of patients for emergency rescue.

Contraindications: contraindications for infants and children with sternal fracture.

9. What are the main technical indicators for the production of cardiopulmonary resuscitation apparatus?

A. Press frequency :100 times /min;

B. Pressing depth :25mm~50mm;

C. Ratio of pressing to breathing :30:2 15:2;

D. Ratio of pressing and relaxing time :1:1;

E. Single respiration :12, 14, 16, 18 times /min;

F. Oxygen transport :200mL/ time ~1200 mL/ time;

G. Zui high safety pressure of mask air path 10kPa;

H. Use of air source: medical oxygen. Working pressure is 0.2MpA-0.4mpa.

10. What does it mean to produce CARDIopulmonary resuscitation (CPR) at a rate of 100 presses /min?

When pressing on the patient's chest, the fast and slow pace should be maintained at 100 times per minute, generally called the compression frequency of 100 times /min. In the rescue process, when pressing to a certain number of times, it is necessary to stop and blow to the patient, so in fact, the number of presses per minute is not 100 times, but less than 100 times. If the ratio of presses to breaths is 15:2, the number of presses per minute is about 70 times. Compressions at a rate of 100 per minute are one of the most important criteria in international guidelines and should be strictly followed during CPR.

11. What is the prescribed pressure depth for the production of CARDIopulmonary resuscitation?

Compression depth refers to the depth of chest depression during chest compressions. This depth is too deep, easy to make the sternum fracture or cause pneumothorax hemothorax disease, not only can not save people, but also attract other injuries. Pressing depth is too shallow, can not start pressing effect. International guidelines stipulate a sternal depression of 4-5cm, and surgery stipulates a sternal depression of 3-4cm. Therefore, XF-5 is designed to be continuously adjustable from 25-50mm, which can be used for rescuing patients with different body types.

12. What is the compression-to-air ratio for the production of CARDIopulmonary resuscitation? How does it work?

Pressing and breathing are cyclical, that is, after pressing for a certain number of times, stop to give the patient a certain number of chi, this is a cycle. In a cycle, the ratio of the number of compressions to the number of aspirates is the ratio of the compressions to the number of breaths. This index has a great influence on the success rate of cardiopulmonary resuscitation. Thus, the international Guide 2000 provides for 15:2 and the International Guide 2005 provides for 30:2, and explicitly states that 5:1 is no longer used. According to this regulation, XF-5 is chosen as 30:2, 15:2 and 5:1(reserved for bidding).

13. Why is the compression/relaxation time ratio for the production of CARDIopulmonary resuscitation apparatus set at 1:1?

Press and relaxation is refers to the chest compressions, rescue workers or recovery machine press head to press hard chest subsidence, cardiac contraction, then no longer pressure or pressure head raised, make a chest bump, diastolic, instead of cardiac autonomic contraction and expansion, achieve the goal of the circulation of the blood, normal cardiac systolic and diastolic time, and the international guidelines, pressure equals the time needed for relaxation. Therefore, XF-5 sets this indicator at 1:1.

14. What are the requirements for the production of cardiopulmonary resuscitation apparatus?

According to the guidelines for clinical application of mechanical ventilation (draft), part 2: setting of tidal volume on mechanical ventilation, 5~12mL/kg is usually selected based on body weight and adjusted in combination with respiratory compliance and resistance. It is pointed out in the article "Application of Ventilator" that adult tidal volume is generally 5~15mL/kg, and 8~12mL/kg is the common range of ZUI. Therefore, the oxygen uptake of XF-5 is designed to be 200mL/ time ~1200mL/ time for users to choose.

15. What is the meaning of the zUI high safety pressure of mask air path 10kPa? How is it guaranteed?

There is a limit to how much pressure a person's lungs can handle, and if the pressure is too high, there is a risk of lung damage. Therefore, the air pressure to the lungs must be strictly controlled. To this end, THE XF-5 is equipped with a safe release device in the breathing channel to ensure that the gas pressure delivered to the patient is within a safe range of less than 10kPa.

16. Why does the production of cardiopulmonary resuscitation apparatus use medical oxygen as power source?

Xf-5 is mainly used in medical institutions to rescue patients who have died suddenly. Medical oxygen is a necessary source of air in medical institutions (such as bottled oxygen and centralized oxygen supply), so there is no need to prepare other sources of air. In addition, the use of medical oxygen is beneficial to the rescue of patients and will not cause harm to the environment.

17. What is the mechanical force of the XF-5 press? Does it meet the requirements?

The size of the pressing mechanical force is proportional to the working pressure and the area of the cylinder piston. The area of the cylinder piston of XF-5 is certain, and the size of the pressing mechanical force is only proportional to the working pressure. The working pressure of the machine is 0.2-0.4mpa, and the calculated pressing mechanical force is 25.12-50.24kg. This mechanical force is in line with international guidelines and is comparable to the mechanical force used when pressing with bare hands.

18. What is the function of the exhalation valve at the respirator mask for the production of cardiopulmonary resuscitation?

Its function is to make the patient's exhaled waste gas is discharged instantly, but does not return to the oxygen pipeline, can keep the gas in the oxygen pipeline clean. In addition, the pressure in the oxygen pipeline can be reduced to normal pressure in an instant, which is conducive to the recovery of the lung to a normal state.
