Problems solved by technology

The current various ventilator equipment is mainly connected to the patient's respiratory system from the mouth and nose, and then helps the patient to inhale and exhale. After the mouth and nose of the mildly ill patient are covered by the breathing mask, they can speak, spit, eat and drink. It is very inconvenient. Many critically ill patients have to perform other operations such as clearing sputum and sewage while assisting breathing. Due to the limited space available at the mouth and nose, sometimes measures such as tracheotomy and intubation have to be performed on the patient in order to support the patient at the same time. Perform a variety of operations to provide sufficient equipment operating space and intervention interface, causing greater damage to the patient's body

Embodiment 1

[0028] Such as figure 1 , figure 2 and image 3As shown, the assisted ventilator of the present invention includes a pressure-bearing shell and a cavity pressure adjustment system, the pressure-bearing shell is arranged around the chest cavity of the human body, and a sealing assembly 5 is provided between the pressure-bearing shell and the human body, wherein the pressure-bearing shell includes an upper bearing The pressure shell 1 and the lower pressure shell 2, and the upper pressure shell 1 and the lower pressure shell 2 are provided with a sealing structure and a locking structure. The sealing structure is specifically composed of an elastomer sealing member 9. The locking structure is specifically For the fastener connection structure 8, the pressure-bearing shell is provided with an underarm port 3 and a waist-abdominal port 4, and a sealing assembly 5 made of elastic material is arranged at the armpit port 3 and the waist-abdominal port 4 respectively. The shape of ...

Embodiment 2

[0039] Such as Figure 4 As shown, the difference between the auxiliary ventilator of the present invention and Embodiment 1 is that the lower pressure-bearing shell is integrated on the hospital bed 14, the upper pressure-bearing shell 1 is directly fixed on the hospital bed 14, and the upper pressure-bearing shell 1 and the hospital bed 14 An elastomer sealing member 9 is provided, and is fixedly connected by a fastener connecting structure 8; in addition, the pressure generator in the chamber pressure regulating system is an air source, specifically including a positive pressure air source 20 and a negative pressure air source 17, positive pressure air source 20 and negative pressure air source 17. The compressed air source 20 and the negative pressure air source 17 communicate with the external breathing chamber 31 through the pipeline 15, and the chamber pressure regulating system also includes a first pressure control valve 19, which is arranged between the air source and...

Embodiment 3

[0047] Such as Figure 5As shown, the difference between the assisted ventilator of the present invention and Embodiment 1 is that the pressure-bearing shell is provided with the neck port 21, the waist and abdomen port 4, and the upper arm port 24, and the sealing assembly 5 is respectively arranged at the neck port 21, the upper arm port 24 and the waist and abdomen port. At the port 4, the shape of the sealing assembly 5 and the contact part of the human body is adapted to the contour of the contact part of the human body; in addition, the safety device provided on the outer breathing chamber 31 includes a positive pressure safety valve 6, a negative pressure safety valve 22 and a normal pressure The reset valve 7, the positive pressure safety valve 6, the negative pressure safety valve 22 and the normal pressure reset valve 7 are all fixedly arranged on the upper pressure shell 1; in addition, it also includes an abdominal breathing restraint device, which is an abdominal b...

Abstract

The invention belongs to the technical field of medical appliances, and discloses an auxiliary breathing machine. The auxiliary breathing machine comprises a pressure-bearing shell and a cavity pressure adjusting system, wherein the pressure-bearing shell is arranged at least at the chest part of a human body; a sealing assembly is arranged between the pressure-bearing shell and the human body; aclosed outer breathing chamber is formed between the pressure-bearing shell and the human body through the sealing assembly; the cavity pressure adjusting system comprises a pressure generator; the pressure generator communicates with the outer breathing chamber; and the cavity pressure adjusting system operates to generate periodically-changed positive pressure and negative pressure, or periodically-changed positive pressure and normal pressure, or periodically-changed negative pressure and normal pressure. The auxiliary respirator disclosed by the invention has the advantages of small pain of patients, safety, reliability, convenience for being used together with other rescue equipment and the like, can be widely applied to emergency rescue or daily nursing of patients with weakened or disappeared spontaneous breathing. The auxiliary breathing machine has a simple application method, is easy to operate and has a wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to an auxiliary ventilator for helping patients who cannot normally breathe spontaneously. Background technique [0002] Aerobic respiration is an important physiological activity for the human body to obtain the oxygen necessary for life. Only by ensuring normal breathing can life be maintained. For some patients who cannot breathe spontaneously due to injuries and other reasons, it is necessary to use a ventilator for breathing assistance or Respiratory rescue. The current various ventilator equipment is mainly connected to the patient's respiratory system from the mouth and nose, and then helps the patient to inhale and exhale. After the mouth and nose of the mildly ill patient are covered by the breathing mask, they can speak, spit, eat and drink. It is very inconvenient. Many critically ill patients have to perform other operations such as clearing sputum and sewage...
