detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments of the description.

As shown in Figure 1, a respirator device for disposable tracheal intubation includes an airbag 1, an oxygen tube 2, and a connecting tube 3. The airbag 1 is an elastic capsule with openings at both ends, and its upper opening is connected to the oxygen tube 2. Its lower opening is connected to the connecting tube 3, and the end of the oxygen tube 2 is connected to the oxygen source. The ends of the connecting tube 3 are respectively provided with a connecting hole 3a and an air outlet hole 3b. Empty, the diameter of the air outlet hole 3b is smaller than that of the connecting hole 3a. As shown in Figure 2-3, an inlet valve 3c is installed in the main pipeline of the connecting pipe 3, and an outlet valve 3d is installed in the air outlet hole 3b. Both the inlet valve 3c and the outlet valve 3d are surrounded by a plurality of fan-shaped elastic pieces 3e. Composition, a plurality of fan-shaped elastic sheets 3e are distributed in a circular array, and their fan-shaped sides are respectively bonded to the inner wall of the connecting pipe 3 and the inner wall of the air outlet 3b, and a plurality of fan-shaped elastic sheets 3e surround to form a tapered funnel body, and the conical shape of the inlet valve 3c The tip faces to the inside of the tube body of the connecting pipe 3, and the tapered tip of the outlet valve 3d faces to the outside. The air bag 1 is used to contract and relax with the patient's spontaneous breathing, which is convenient for observing the recovery of the patient's spontaneous breathing. The one-way cut-off function of the inlet valve 3c and the outlet valve 3d can provide different airflow paths for inhalation and exhalation.

When the patient's spontaneous breathing shows a tendency to inhale, the connecting hole 3a connected to the endotracheal tube has negative pressure, while the air bag 1 and the oxygen source connected to the connecting tube 3 are under positive pressure, resulting in a pressure difference between the upper and lower ends of the inlet valve 3c. Make the oxygen pressure act on the fan-shaped elastic piece 3e of the inlet valve 3c to make it be pushed downward and bend. At this time, the negative inspiratory pressure of the patient also serves as an auxiliary effect to make the fan-shaped elastic piece 3e bend and move down, forming the state shown in Figure 4. At this time, the conical tip of the inlet valve 3c is squeezed by the gas to form an opening, so that the oxygen in the oxygen source enters the inlet valve 3c in the open state along with the air bag 1 and the connecting tube 3, and then flows to the endotracheal tube connected to the connecting hole 3a at the right end And enter the patient's body, at the same time, because the conical tip of the air outlet valve in the left end air outlet 3b is facing the outside, it is extremely difficult for the fan-shaped elastic piece 3e of the air outlet valve to bend inward, so it has a relatively stable resistance to the airflow from outside to inside The structure isolates the air from the outlet valve, so that the outside air will not infiltrate through the outlet hole 3b with the patient's inhalation, so as to ensure that the patient can absorb high-concentration oxygen to improve respiratory function, and further achieve effective postoperative recovery treatment .

When the patient's spontaneous breathing shows a tendency to exhale, the expiratory airflow enters the connection hole 3a along with the tracheal intubation, so that the air pressure difference between the two ends of the inlet valve 3c decreases, and the fan-shaped elastic piece 3e of the inlet valve 3c returns to its natural straight state , a plurality of fan-shaped elastic pieces 3e are re-attached and closed after returning to straightness, so that the inlet valve 3c is closed, forming a state as shown in Figure 5; There is an air pressure difference on both sides of the outlet valve 3d in the air hole 3b, thereby pushing and bending the fan-shaped elastic piece 3e of the outlet valve 3d toward the left (direction as shown in Figure 5), and the outlet valve 3d is opened after a plurality of fan-shaped elastic pieces 3e are squeezed apart , so that the carbon dioxide exhaled by the patient can be discharged smoothly. At this time, the inlet valve 3c is in a closed state, so it can ensure that high-purity oxygen will not be discharged to the outside world, preventing waste of resources and avoiding carbon dioxide accumulation.

When the patient’s exhalation phase is over, the pressure difference between the two ends of the outlet valve decreases and closes again, returning to the state shown in Figure 2, and re-entering the next breathing phase, so as to achieve high-efficiency oxygen supply and exhaust functions. Because there is no need to install an additional ventilator device, it is low in cost, easy to assemble and operate, and can smoothly discharge carbon dioxide so that the oxygen concentration inhaled by the patient reaches 99%, which is very conducive to the patient's postoperative spontaneous breathing recovery treatment.

In this embodiment, the sector-shaped elastic piece 3e is made of corrosion-resistant stainless steel, which can ensure that it will not be affected by corrosion during long-term contact with the patient's cough sputum, and ensure the durability of the inlet valve 3c and outlet valve 3d.

In this embodiment, the airbag 1 is made of medical silica gel material, so as to ensure the elasticity of the thin layer of the airbag 1, and utilize its non-toxic and non-irritating characteristics, which can effectively prevent allergic reactions and body rejection reactions of the gas-introduced patients. To ensure the therapeutic effect.

In this embodiment, the connecting pipe 3 is made of antibacterial glass material, and the all-weather bacteriostatic function of the antibacterial glass is used to ensure the aseptic cleanliness of the gas delivery space in the pipeline. In order to disassemble and maintain in time to ensure patient safety.

In this embodiment, the contact parts of the inlet valve 3c and the outlet valve 3d with the inner wall of the connecting pipe 3 and the inner wall of the air outlet hole 3b are adhered and butted by medical adhesive 3f. The non-toxic properties of the medical adhesive 3f are used to ensure the cleanliness of the gas in the pipeline of the connecting pipe 3 .

In this embodiment, the opening of the bottom end of the connecting tube 3 is embedded with a piston 3g. When the patient's coughing sputum accumulates in the bottom end of the connecting tube 3 along with the pipeline, the accumulated fluid can be quickly discharged by removing the piston 3g, and then restarted. Put it back in place, this process does not need to disassemble the oxygen supply system of the tracheal intubation, and can perform synchronous maintenance operations at any time during the treatment process to ensure the efficiency of recovery treatment.

The embodiments described above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those of ordinary skill in the art, without departing from the scope of features defined in the claims, The utility model can also be modified, changed and equivalently replaced in other forms, all of which should belong to the protection scope of the utility model.
