Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically a ventilator for respiratory medicine. Background Technology

[0002] Ventilators used in respiratory medicine are crucial equipment in clinical treatment. They can effectively replace or assist spontaneous breathing when a patient's respiratory function is impaired. By precisely adjusting a series of important parameters such as respiratory rate, tidal volume, inspiratory time, and expiratory time, ventilators can accurately adapt to the individual needs of different patients, maintain normal and stable respiratory function, significantly improve hypoventilation or hyperventilation, and make the patient's breathing more regular, smooth, and efficient. In this process, ventilators can greatly reduce the workload of respiratory muscles, allowing them to rest fully after being under high load for a long time, effectively relieving respiratory muscle fatigue and creating favorable conditions for their functional recovery. In addition, ventilators use scientific methods such as positive pressure ventilation, which can deeply improve the gas distribution in the lungs, significantly increase alveolar ventilation, not only help to quickly reduce pulmonary edema symptoms, but also promote the re-expansion of atelectasis, and comprehensively improve the oxygenation function of the lungs. For patients suffering from respiratory failure, severe dyspnea, and various lung diseases such as pneumonia, chronic obstructive pulmonary disease, and acute respiratory distress syndrome, ventilators can ensure that all organs of the body receive sufficient oxygen supply, effectively preventing multi-organ dysfunction caused by hypoxia and carbon dioxide retention. They play an irreplaceable and important role in clinical treatment and patient rehabilitation, and are a solid guarantee for protecting patients' lives and health.

[0003] While the breathing masks used with existing ventilators are suitable for most people, a small number of people may have gaps between the breathing mask and their face due to different facial features, such as excessive facial hair or jawbone deformities. Generally, small gaps do not prevent patients from receiving oxygen, but in some special cases, they can harm the surrounding medical staff.

[0004] Ventilators are not only an effective means of artificially replacing spontaneous breathing, but during general anesthesia, the oxygen in the ventilator is mixed with anesthetic. This anesthetic can help the patient enter a deep sleep state. When the patient inhales, the breathing mask creates a short-term negative pressure, which increases the fit between the mask and the face. When the patient exhales, the negative pressure disappears, and the breathing mask and face return to their original shape, exposing the gap. The gas containing anesthetic can then escape through this gap and be pushed out by the patient's exhalation. Over time, this can affect medical staff. Utility Model Content

[0008] Preferably, two sets of fixing brackets are fixedly installed on the inner bottom wall of the box. The inner walls of the two sets of fixing brackets are fixedly installed to the outer surfaces of the air inlet detection pipe and the air outlet detection pipe, respectively. An air vent is opened on the inner side of the box. An air collecting cylinder is fixedly installed at both ends of the air inlet detection pipe and the air outlet detection pipe. The air collecting cylinder is installed on the inner wall of the box located at the air vent. The interior of the air collecting cylinder is interconnected with the interior of the air inlet detection pipe and the air outlet detection pipe, respectively.

[0009] Preferably, a rotating seat is fixedly installed on the inner surface of both the air inlet detection tube and the air outlet detection tube. A rotating rod is rotatably connected to the inner wall of the rotating seat. The outer surface of the rotating rod is fixedly installed to the outer surface of the detection blade. The screw directions of the detection blades on the inner walls of the air inlet detection tube and the air outlet detection tube are opposite to each other.

[0010] Preferably, mounting brackets are fixedly installed on the inner surfaces of the air collection cylinders at both ends of the air inlet detection tube and the air outlet detection tube. The inner walls of the mounting brackets at the same end of the air inlet detection tube and the air outlet detection tube are fixedly installed to the outer surfaces of the infrared receiver and the infrared transmitter, respectively. The infrared transmitter and the infrared receiver are installed in opposite directions on the mounting brackets at the other end of the air inlet detection tube and the air outlet detection tube.

[0011] Preferably, a fixed cylinder is fixedly installed on the outer surface of the housing at the vent.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes the coordination of an inlet detection tube, an outlet detection tube, detection blades, an infrared transmitter, and an infrared receiver. One end of the inlet detection tube is connected to the inlet tube of the patient's breathing mask, and the other end is connected to the delivery tube of the ventilator. One end of the outlet detection tube is connected to the outlet tube of the patient's breathing mask, and the other end is connected to the exhaust tube of the ventilator. Therefore, when the patient inhales, gas can pass through the inlet detection tube and push the internal detection blades to rotate into the breathing mask. When the patient exhales, the exhaled gas will pass through the outlet detection tube and push the internal detection blades to rotate. When a gap appears between the patient's face and the breathing mask, causing exhaled gas to leak, the airflow in the outlet detection tube will definitely be less than [a certain value]. The intake detection tube ensures that the rotation speed or single rotation duration of the detection blades in the exhaust detection tube is less than that of the detection blades in the intake detection tube. The infrared emitter emits invisible light that is received by the infrared receiver. When the detection blades rotate, they can block the infrared light, but the infrared light can still pass through the gaps between the detection blades and be received by the infrared receiver. The infrared receiver is externally connected to the controller of the ventilator. The controller can calculate the intake and expiration volumes based on the infrared light reception frequencies in the exhaust and intake detection tubes. When the expiration volume is lower than the intake volume, the buzzer on the ventilator will sound to alert medical staff, thus solving the problem of anesthetic gas leaking out.

[0015] 2. This application utilizes the cooperation between the rotating rod, the rotating seat, and the detection blade. The rotating seat can provide support for the detection blade through the rotating rod, and the rotating seat is equipped with a bearing inside. The bearing is sleeved on the outer surface of the rotating rod, making the rotating rod more flexible when rotating, and enabling the detection blade to be rotated more sensitively by the gas.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a technical solution for a ventilator used in respiratory medicine, including a housing 1. Inside the housing 1 are an inlet detection tube 2 and an outlet detection tube 3. Both the inlet and outlet detection tubes 2 and 3 have detection blades 4 inside. An infrared transmitter 5 is installed at one end of each inlet and outlet detection tube 3, and an infrared receiver 6 is installed at the other end. One end of the inlet detection tube 2 is connected to the inlet tube of the patient's breathing mask, and the other end is connected to the ventilator's delivery tube. One end of the outlet detection tube 3 is connected to the outlet tube of the patient's breathing mask, and the other end is connected to the ventilator's exhaust tube. Therefore, when the patient inhales, gas can pass through the inlet detection tube 2 and push the internal detection blades 4 to rotate and enter the breathing mask. When the patient exhales, the expelled gas will pass through the outlet detection tube 3 and push the internal detection blades 4 to rotate. When a gap appears between the patient's face and the breathing mask, causing exhaled air to leak, the airflow in the exhaust detection tube 3 will be less than that in the intake detection tube 2. Consequently, the rotation speed or single rotation duration of the detection blades 4 in the exhaust detection tube 3 will be less than that in the intake detection tube 2. The infrared emitter 5 emits invisible light that is received by the infrared receiver 6. When the detection blades 4 rotate, they can block the infrared light. During this time, the infrared light can pass through the gaps between the detection blades 4 and be received by the infrared receiver 6. The infrared receiver 6 is externally connected to the ventilator's controller. The controller can calculate the intake and exhalation volumes based on the infrared light receiving frequencies in the exhaust and intake detection tubes 3 and 2. When the exhalation volume is lower than the intake volume, the ventilator's built-in buzzer will sound to alert medical staff, thus solving the problem of anesthetic gas leaking out.

[0024] A partition 7 is fixedly installed on the inner wall of the housing 1 between the air inlet detection pipe 2 and the air outlet detection pipe 3. A load-bearing plate 8 is fixedly installed on the outer surface of the partition 7. A battery 9 is fixedly installed on the outer surface of the load-bearing plate 8. The partition 7 can isolate the air inlet detection pipe 2 and the air outlet detection pipe 3. The load-bearing plate 8 can provide support for the battery 9. The battery 9 can power the infrared transmitter 5 and the infrared receiver 6, so that the device can be used in conjunction with a ventilator in an ambulance or temporary ward.

[0025] Two sets of fixing brackets 10 are fixedly installed on the inner bottom wall of the housing 1. The inner walls of the two sets of fixing brackets 10 are fixedly installed to the outer surfaces of the air inlet detection pipe 2 and the air outlet detection pipe 3, respectively. An air vent 11 is opened on the inner side of the housing 1. An air collecting cylinder 12 is fixedly installed at both ends of the air inlet detection pipe 2 and the air outlet detection pipe 3. The air collecting cylinder 12 is installed on the inner wall of the housing 1 located at the air vent 11. The interior of the air collecting cylinder 12 is interconnected with the interior of the air inlet detection pipe 2 and the air outlet detection pipe 3, respectively. The fixing brackets 10 can provide support for the air inlet detection pipe 2 and the air outlet detection pipe 3. The air collecting cylinder 12 can concentrate air into the smaller diameter air inlet detection pipe 2 or the smaller diameter air outlet detection pipe 3. By reducing the air flow area, the air flow velocity is increased, so that the detection blade 4 can be more obviously driven to rotate by the air.

[0026] Rotary seats 13 are fixedly installed on the inner surfaces of both the inlet detection pipe 2 and the outlet detection pipe 3. A rotating rod 14 is rotatably connected to the inner wall of the rotating seat 13. The outer surface of the rotating rod 14 is fixedly installed to the outer surface of the detection blade 4. The screw directions of the detection blades 4 on the inner walls of the inlet detection pipe 2 and the outlet detection pipe 3 are opposite to each other. The rotating seat 13 can provide support for the detection blades 4 through the rotating rod 14. Furthermore, a bearing is installed inside the rotating seat 13, and the bearing is sleeved on the outer surface of the rotating rod 14, making the rotating rod 14 more flexible when rotating, so that the detection blades 4 can be more sensitively driven to rotate by the gas.

[0027] Mounting brackets 15 are fixedly installed on the inner surfaces of the air collection cylinders 12 at both ends of the air inlet detection pipe 2 and the air outlet detection pipe 3. The inner walls of the mounting brackets 15 at the same end of the air inlet detection pipe 2 and the air outlet detection pipe 3 are fixedly installed to the outer surfaces of the infrared receiver 6 and the infrared transmitter 5, respectively. The infrared transmitter 5 and the infrared receiver 6 are installed in opposite directions on the mounting brackets 15 at the other end of the air inlet detection pipe 2 and the air outlet detection pipe 3. The mounting brackets 15 can provide support for the infrared receiver 6 or the infrared transmitter 5. An infrared receiver 6 and an infrared transmitter 5 are respectively provided at both ends of the air inlet detection pipe 2 or the air outlet detection pipe 3.

[0028] A fixed cylinder 16 is fixedly installed on the outer surface of the vent 11 of the housing 1. The wires of the infrared transmitter 5 and the infrared receiver 6 pass through the fixed cylinder 16. A connecting tube 17 is slidably connected to the inner wall of the fixed cylinder 16. A one-way valve 18 is fixedly installed on the inner wall of the fixed cylinder 16. The outer surface of the one-way valve 18 is in close contact with the outer surface of the connecting tube 17. The interior of the connecting tube 17 is interconnected with the interior of the air inlet detection tube 2 and the air outlet detection tube 3 through the fixed cylinder 16 and the vent 11, respectively. The one-way valve 18 can reduce the impact of external dust or impurities on the detection data when the equipment is not in use. The one-way valve 18 can be opened after the connecting tube 17 is inserted.

[0029] A retainer 19 is fixedly connected to the outer surface of the fixed cylinder 16, and a retaining block 20 is fixedly installed on the outer surface of the connecting tube 17. A hard rubber plate 21 is fixedly installed on the inner side wall of the retainer 19, and a soft rubber plate 22 is fixedly installed on the outer surface of the retaining block 20. The outer surfaces of the hard rubber plate 21 and the soft rubber plate 22 are in mutual frictional contact. When installing the connecting tube 17, the connecting tube 17 can be inserted into the fixed cylinder 16 first, and then rotated clockwise by 30°. When the connecting tube 17 rotates, it can drive the retaining block 20 on the surface into the retainer 19 on the surface of the fixed cylinder 16. The soft rubber plate 22 on the retaining block 20 and the hard rubber plate 21 on the retainer 19 are in mutual frictional contact to reduce the possibility of loosening.
