Description

Technical Field

[0001] The present invention relates to the technical field of respiratory recovery devices, and in particular to a respiratory recovery device for critical care medicine. Background Art

[0002] The respiratory resuscitation device in the critical care medicine department is a medical device specially used for respiratory support for critically ill patients, designed to help patients restore normal respiratory function. The device combines advanced ventilation technology and can provide effective respiratory support for patients who require mechanical ventilation and reduce their respiratory burden. The respiratory resuscitation device can achieve precise regulation of the patient's breathing, ensure ventilation and oxygenation of the lungs, and prevent further aggravation of respiratory failure. With the continuous advancement of technology, modern respiratory resuscitation devices can provide patients with safer and more comfortable respiratory support. Through these functions, respiratory resuscitation devices play a vital role in critical care medicine and significantly improve patients' survival rate and quality of life.

[0003] After searching, the invention patent of Chinese patent number CN117339073B discloses an oxygen inhalation tube for preventing nasal moisture and itching, including a body and an oxygen mask, the surface of the oxygen mask is fixedly connected with a connecting tube, the outer surface of the connecting tube is fixedly connected with a branch tube, the surface of the branch tube is provided with a water absorption component, the surface of the branch tube is inserted with a sputum suction component, and the inner surface of the sputum suction component is provided with an anti-backflow component. The critical care medicine respiratory recovery device is provided with a water absorption component, a sputum suction component and an anti-backflow component. The water absorption component can not only make the patient's face and the oxygen mask fit more closely, but also improve the effect and efficiency of the water absorption component on the water suction inside the oxygen mask. The sputum suction component can not only perform sputum suction work on the patient's throat, but also prevent the patient from being choked by saliva. The anti-backflow component prevents the phenomenon of sputum reflux inside the sputum suction tube, and the structure of the quick disassembly and assembly of the clamping seat makes the cleaning and disinfection of the surface structure of the clamping seat more efficient after use. Compared with the existing technology, the invention patent with Chinese patent number CN117339073B is designed to solve the problem that critically ill patients often have lung infections due to long-term bed rest, and such patients have more respiratory secretions. When patients use respiratory recovery devices, respiratory secretions will block oxygen, thereby affecting oxygen supply.

[0004] However, in actual use of the above device, the connection process between the oxygen tube and the oxygen mask is time-consuming and the assembly efficiency is poor. Since most patients suffer from lung infections, they often cough during the installation, and the coughing process will pull the oxygen tube to move, causing the connection of the oxygen tube to loosen. In addition, the device lacks a response mechanism after a ventilator failure or a disconnection of the pipeline, and its safety is insufficient. Therefore, a critical care medicine respiratory resuscitation device is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art, that is, the connection process between the oxygen tube and the oxygen mask is time-consuming and the assembly efficiency is poor. Since most patients suffer from lung infections, they often cough during the installation, and the coughing process will pull the oxygen tube to move, causing the connection of the oxygen tube to loosen. In addition, the device lacks a response mechanism after a ventilator failure or pipeline disconnection, and the safety is insufficient. A critical care medicine respiratory recovery device is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A respiratory recovery device for critical care medicine, comprising a ventilator, an air bag is arranged at the upper end of the ventilator, a humidification bottle is fixedly connected to the rear end of the air bag, an oxygen supply tube is fixedly connected to the front end of the humidification bottle, an oxygen mask is arranged at the end of the oxygen supply tube away from the humidification bottle, a connecting tube is arranged at the lower part of the oxygen mask, the diameter of the oxygen supply tube is larger than the connecting tube and can be inserted into the connecting tube, a fixing ring is fixedly connected to the bottom of the connecting tube, and three fixing mechanisms are arranged around the outer wall of the fixing ring;

[0008] A fixing plate is provided at the bottom of the fixing mechanism, and the fixing mechanism can drive the fixing plate to move to fix the oxygen supply pipe and the connecting pipe. An exhaust pipe is provided on the upper part of the connecting pipe, and the exhaust pipe is fixedly connected to the oxygen mask. A plurality of exhaust holes are provided on the side of the exhaust pipe away from the oxygen mask, and an exhaust mechanism is provided inside the exhaust pipe, and the flow rate of gas in the exhaust pipe can be controlled by the exhaust mechanism.

[0009] The above technical solution further includes:

[0010] The fixing mechanism comprises a fixing shell fixedly connected to a fixing ring, a first motor is arranged inside the fixing shell, and a fixing component is arranged at an output end of the first motor.

[0011] The fixed component includes a first transmission wheel arranged at the output end of the first motor, the first transmission wheel is connected to a transmission belt, the transmission belt is connected to a second transmission wheel on a side away from the first transmission wheel, the second transmission wheel is rotationally connected to the fixed shell, and an eccentric shaft is fixedly connected to the bottom of the second transmission wheel.

[0012] The bottom of the eccentric shaft is rotatably connected with a connecting piece, a side of the connecting piece away from the eccentric shaft is rotatably connected with a fixing plate, and the fixing plate is slidably connected with the fixed shell.

[0013] The exhaust mechanism includes a valve housing fixedly connected inside the exhaust pipe, and two valves are rotatably connected inside the valve housing. The relatively large positive pressure inside the exhaust pipe can drive the valve to rotate and exhaust, while the gas reflux outside the exhaust pipe will drive the valve to close.

[0014] Two control mechanisms are fixedly connected to the upper part of the valve housing. The control mechanism comprises a control shell fixedly connected to the valve housing. A second motor is arranged inside the control shell, and a control component is arranged at an output end of the second motor.

[0015] The control assembly includes a first gear disposed at the output end of the second motor, the first gear is meshedly connected with a second gear, the second gear is rotationally connected to a control housing, and a valve is fixedly connected to a side of the second gear away from the first gear.

[0016] The oxygen mask is fixedly connected with fixing belts on both sides, and one of the fixing belts is fixedly connected with a fixing buckle at one end away from the oxygen mask. The two fixing belts can be fixed by the fixing buckle, and the fixing buckle is fixedly connected with a soft cushion on one side close to the sealing air cushion.

[0017] The upper end of the oxygen mask support is fixedly connected with an inflation port, and a sealing air cushion is fixedly connected to the inflation port near the oxygen mask. The sealing air cushion is fixed around the bottom of the oxygen mask, and air can be inflated into the sealing air cushion through the inflation port.

[0018] A piston is slidably connected inside the inflation port, a limit ring is fixedly connected to the rear end of the piston, and a plurality of notches are provided at the connection portion between the piston and the limit ring.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, when connecting the oxygen supply tube and the oxygen mask, the personnel only need to insert the oxygen supply tube into the connecting tube and start the three fixing mechanisms arranged on the fixing ring. The fixing mechanisms can drive the fixing plate arranged at the bottom to move, so that the oxygen supply tube is tightly fixed to the outside of the connecting tube, which not only effectively improves the efficiency of the oxygen supply tube and the oxygen mask when they are assembled and connected, but also ensures the stability of the oxygen supply tube and the oxygen mask when they are connected, and effectively prevents the oxygen supply tube from moving when the patient coughs and loosens the connection. When the device is used, the patient's exhalation can drive the valve in the valve housing to rotate and open, and the gas in the oxygen mask is discharged. When the gas outside the exhaust pipe flows into the valve, the valve will rotate and close to prevent the outside gas from entering the oxygen mask and causing pollution. When the ventilator fails or the pipeline is disconnected, the valve can be forcibly controlled to rotate and open through the control mechanism, and the patient can breathe through the exhaust pipe, thereby improving safety.

[0021] 2. In the present invention, when in use, the mouth and nose are covered in the oxygen mask, and the fixing belt is used to fasten the oxygen mask to the head, so that the oxygen mask fits the face, thereby forming a relatively closed cavity and connecting to the ventilator pipeline. However, the oxygen mask is set according to the conventional structure of the human face, and the facial structure of each person is different. Therefore, during use, the oxygen mask structure is often not suitable, resulting in air leakage. The sealing air cushion can be inflated through the inflation port, and the sealing air cushion can fit tightly with the patient's facial skin after inflation, thereby effectively improving its air tightness.

[0037] The exhaust mechanism includes a valve housing 23 fixedly connected to the inside of the exhaust pipe 7, and two valves 24 are rotatably connected to the inside of the valve housing 23. The relatively large positive pressure in the exhaust pipe 7 can drive the valve 24 to rotate and exhaust, and the gas reflux outside the exhaust pipe 7 will drive the valve 24 to close. Two control mechanisms are fixedly connected to the upper part of the valve housing 23, and the control mechanism includes a control shell 25 fixedly connected to the valve housing 23.

[0038] In the present embodiment, when in use, the oxygen supply tube 4 can be first inserted into the connecting tube 9, and then the first motor 15 inside the fixed housing 10 is started, and the first motor 15 can drive the first transmission wheel 16 to rotate, and the rotation of the first transmission wheel 16 can drive the second transmission wheel 18 connected by the transmission belt 17 to rotate, and the rotation of the second transmission wheel 18 can drive the fixedly connected eccentric shaft 19 to rotate, and the rotation of the second transmission wheel 18 can drive the connecting member 20 to rotate, and the connecting member 20 can drive the fixing plate 21 to reciprocate, and the fixing plate 21 is controlled by the first motor 15 to gradually move downward, and when the fixing plate 21 moves to the lowest point, the oxygen supply tube 4 and the connecting tube 9 can be firmly clamped and fixed, thereby ensuring the stability of the oxygen supply tube 4 when connected to the oxygen mask 5, and when the oxygen supply tube 4 needs to be disassembled or replaced, it is only necessary to control the eccentric shaft 19 to rotate again to drive the fixing plate 21 to move upward, thereby releasing the clamping, and effectively improving the efficiency of assembling or disassembling the oxygen supply tube 4 and the oxygen mask 5;

[0039] When the device is in use, the ventilator 1 can drive the airbag 2 to contract, and the contraction of the airbag 2 can deliver oxygen into the humidification bottle 3. After being moistened by the humidification bottle 3, the oxygen can be delivered to the inside of the oxygen mask 5 through the oxygen supply tube 4 for the patient to absorb.

The rotation of the first gear 27 can drive the second gear 28 to rotate as well, thereby forcibly controlling the valve 24 to rotate and open, and the patient can breathe through the exhaust pipe 7, thereby improving the safety of the device.

[0040] Embodiment 2

[0041] like Figure 1-Figure 9As shown, the oxygen mask 5 is fixedly connected with fixing belts 6 on both sides, and one of the fixing belts 6 is fixedly connected with a fixing buckle 14 at one end away from the oxygen mask 5, and the two fixing belts 6 can be fixed by the fixing buckle 14, and the fixing buckle 14 is fixedly connected with a soft cushion 11 on one side close to the sealing air cushion 12;

[0042] An inflation port 13 is fixedly connected to the upper end of the oxygen mask 5, and a sealing air cushion 12 is fixedly connected to the inflation port 13 near the oxygen mask 5. The sealing air cushion 12 is fixed around the bottom of the oxygen mask 5, and air can be inflated into the sealing air cushion 12 through the inflation port 13. A piston 29 is slidably connected to the inside of the inflation port 13, and a limit ring 30 is fixedly connected to the rear end of the piston 29. A plurality of notches are provided at the connecting portion between the piston 29 and the limit ring 30.

[0043] In this embodiment, when in use, a person can put the patient's mouth and nose into the oxygen mask 5, then fasten it to the head through the fixing belt 6, and then fix the fixing belt 6 through the fixing buckle 14, so that the oxygen mask 5 fits the face, thereby forming a relatively closed cavity and connecting it to the oxygen supply tube 4, and the soft pad 11 provided on the fixing buckle 14 can also ensure that the fixing buckle 14 will not touch the back of the patient's head during connection, thereby causing discomfort;

[0044] However, the oxygen mask 5 is set according to the conventional structure of the human face, and the facial structure of each person is different. Therefore, during use, the oxygen mask 5 may not fit the structure, resulting in air leakage. At this time, air can be inflated into the sealing air cushion 12 through the inflation port 13. During inflation, the piston 29 inside the sealing air cushion 12 moves inward, and the limiting ring 30 can limit the piston 29. The gas can enter through the groove between the piston 29 and the limiting ring 30. When the inflation is completed, the inside of the sealing air cushion 12 is under positive pressure, and the piston 29 can be pushed outward, so that the piston 29 fits against the inner wall of the inflation port 13, thereby closing the inflation port 13. The inflated sealing air cushion 12 can fit tightly against the patient's facial skin, thereby effectively improving its air tightness.
