Description

Technical Field

[0001] The present invention relates to the technical field of medical respiratory assistance, and particularly to a multifunctional respiratory assistance device for intensive care. Background Art

[0002] In the intensive care unit, since most critically ill patients have difficulty breathing, a ventilator is needed to act as an "artificial lung" to assist the patient in breathing.

[0003] The ventilator is connected to the upper respiratory tract and, by periodically inflating and deflating, introduces a mixture of high-concentration oxygen and air into the respiratory tract of critically ill patients, reducing the breathing effort of conscious patients. For some patients in a coma, unconscious, or undergoing general anesthesia surgery, the timed gas delivery function of the ventilator is also needed to maintain the normal respiratory rhythm of the patient.

[0004] Respiratory assistance devices such as ventilators are widely used in hospital intensive care units. However, most patients in intensive care units are in a coma. In addition to using the breathing mask of the ventilator to supply oxygen at the mouth and nose, in some cases, a nebulization mechanism is also needed to input nebulized drugs into the breathing mask. Most ventilator masks do not take into account the use of nebulization inhalation. Since most critically ill patients can only take shallow breaths, and the nebulized drugs cannot be accurately introduced into the nasal respiratory tract of the patient inside the mask, the nebulized drugs are prone to excessive dispersion, affecting the effect of nebulization inhalation. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional respiratory assistance device for intensive care, so as to solve the problem that when using a nebulization mechanism to input nebulized drugs into a breathing mask, the mask of the ventilator does not take into account the use of nebulization inhalation. Since most critically ill patients can only take shallow breaths, the nebulized drugs cannot be accurately introduced into the nasal respiratory tract of the patient inside the mask, and at the same time, the nebulized drugs are also prone to excessive dispersion inside the mask, affecting the effect of nebulization inhalation.

[0006] To achieve the above object, the present invention provides a multifunctional respiratory assistance device for intensive care, including a base frame. An elevating mechanism is installed on the base frame. Casters are provided at the bottom end of the base frame. A display mechanism and a respiratory mechanism are provided at the topmost end of the base frame. The respiratory mechanism is installed on the column of the base frame, and the respiratory mechanism is connected to the elevating mechanism. The respiratory mechanism includes a ventilator main body and a mask assembly. The ventilator main body is connected to the elevating mechanism. The mask assembly is connected to the ventilator main body through a hose. An atomization assembly includes an atomization main body and an atomization output assembly. The atomization main body is installed on the elevating mechanism and is located above the respiratory mechanism. The atomization output assembly is detachably connected to the mask assembly. A guiding and regulating mechanism for guiding the output end of the atomization output assembly to face the patient's nasal cavity is provided inside the mask assembly.

[0007] As a further improvement of the technical solution, the guiding and regulating mechanism includes a guiding channel, a guiding insertion rod and a partition assembly. The guiding channel is provided on the mask assembly. The guiding insertion rod is inserted into the guiding channel, and a limiting rubber sheet is surrounded at the connection between the guiding insertion rod and the guiding channel. A clamping mechanism capable of clamping the edge of the output end of the atomization output assembly is provided at the end of the guiding insertion rod passing through the guiding channel. The partition assembly is provided at the connection between the guiding channel and the mask assembly.

[0008] As a further improvement of the technical solution, the clamping mechanism includes a horizontal clamping frame, a movable clamping frame and a control mechanism. The horizontal clamping frame is an L-shaped frame, and the long frame body of the horizontal clamping frame is provided at the bottom end of the guiding insertion rod. The movable clamping frame is rotatably installed on the horizontal clamping frame, and the movable clamping frame and the short frame body of the horizontal clamping frame form a clamping portion. The control mechanism is provided on the horizontal clamping frame and the guiding insertion rod, and the control mechanism acts on the movable clamping frame to make the movable clamping frame keep a tendency to rotate towards the short frame body portion of the horizontal clamping frame.

[0009] As a further improvement of the technical solution, the control mechanism includes an extrusion spring, an outer pull rod and a control rod. An installation cross plate is provided on the long frame body of the horizontal clamping frame. The extrusion spring is provided on the installation cross plate, and the extrusion spring acts on the movable clamping frame to make the movable clamping frame keep a tendency to rotate towards the short frame body of the horizontal clamping frame. One end of the outer pull rod is rotatably connected to the movable clamping frame, and the other end movably penetrates the installation cross plate and is connected to the control rod. The control rod is parallel to the guiding insertion rod, and the control rod passes through the limiting rubber sheet at the connection between the guiding insertion rod and the guiding channel.

[0010] As a further improvement of the technical solution, a guiding block is provided on the long frame body of the horizontal clamping frame. A guiding groove is provided on the guiding block, and the outer pull rod fits against the inner wall of the guiding groove.

[0011] As a further improvement of the present technical solution, the partition assembly includes an opening and closing partition board, a retracting spring and a pressing side frame. The opening and closing partition board is arranged at the center inside the mask assembly. The opening and closing partition board includes two sections of board bodies, and one section of the board body is fixedly arranged inside the mask assembly, and the other section of the board body is slidably installed on the fixed board body. The retracting spring is arranged on the inner wall of the mask assembly, and the end of the retracting spring is connected to the sliding board body, so that the sliding board body maintains a tendency to slide upward and fit the fixed board body. The pressing side frame is arranged on the sliding board body, and one end of the pressing side frame is located directly below the guiding insertion rod, so that when the guiding insertion rod moves downward, it can squeeze the sliding board body to slide downward, so that the sliding board body and the fixed board body can form a partition inside the mask assembly.

[0012] As a further improvement of the present technical solution, the mask assembly includes a plastic mask and a locking band. The plastic mask is a transparent mask. The guiding channel is arranged on the outer wall of the plastic mask. There are two sockets on the guiding channel, and one of the sockets is connected to the hose of the ventilator main body.

[0015] 1. Through the combined action of the breathing mechanism, the atomization component and the guiding and regulating mechanism, the present invention can form a clamp on the output end of the atomization component through the clamping mechanism, and through the guiding and multi-directional rotation of the guiding insertion rod passing through the guiding channel, control the atomization pipeline at the output end of the atomization component to approach the outside of the respiratory tract of the critically ill patient, so that the atomized drug is accurately input to the patient's respiratory tract inside the mask of the ventilator, ensuring the atomized drug inhalation effect when the critically ill patient takes a shallow breath;

[0016] 2. Through the two sections of the board body of the partition assembly sliding down and separating the internal space of the mask as the guiding insertion rod is inserted, the space of the mask outside the nasal respiratory tract of the patient is reduced, so that the atomized drug introduced at the output end of the atomization component is kept as much as possible at the patient's respiratory tract, preventing the atomized drug from being overly dispersed, and adapting to the atomized drug inhalation of the critically ill patient with shallow breathing.

[0029] Embodiment 1

[0030] Referring to Figures 1-8 , a multifunctional respiratory assistance device for intensive care. In order to guide the atomization pipeline close to the outside of the respiratory tract of critically ill patients and accurately input the atomized medicine into the patient's respiratory tract within the breathing mask, thereby enhancing the atomization inhalation effect of the patient, it is provided with a base frame 1. An elevating mechanism is installed on the base frame 1. Casters 2 are provided at the bottom end of the base frame 1, and a display mechanism 3 is provided at the topmost end of the base frame 1;

[0031] A breathing mechanism 4 is installed on the column of the base frame 1, and the breathing mechanism 4 is connected to the elevating mechanism. The breathing mechanism 4 includes a ventilator main body 401 and a mask assembly. The ventilator main body 401 is a commonly used medical ventilator device, which will not be elaborated here. The ventilator main body 401 is connected to the elevating mechanism. The elevating mechanism is a jacking mechanism driven by a cylinder, which will not be elaborated here. And a mounting base is provided at the jacking end of the cylinder. The ventilator main body 401 is arranged on the base, and the ventilator main body 401 is driven to lift by the cylinder. The mask assembly is connected to the ventilator main body 401 through a hose;

[0032] An atomization assembly 5 includes an atomization main body 501 and an atomization output assembly. The atomization main body 501 is a commonly used medical atomization device, which will not be elaborated here. The atomization main body 501 is installed on the elevating mechanism, and the atomization main body 501 is located above the breathing mechanism 4. The atomization output assembly is detachably connected to the mask assembly, and a guiding and regulating mechanism for guiding the output end of the atomization output assembly to face the patient's nasal cavity is provided inside the mask assembly.

[0033] The guiding and regulating mechanism includes a guiding channel 6, a guiding insertion rod 7, and a partition component 8. The guiding channel 6 is arranged on the mask assembly. The guiding insertion rod 7 is inserted into the guiding channel 6, and a limiting rubber sheet is surrounded at the connection between the guiding insertion rod 7 and the guiding channel 6, so that the guiding insertion rod 7 can be pulled and rotated in multiple directions on the guiding channel 6. A clamping mechanism capable of clamping the edge of the output end of the atomization output assembly is provided at the end of the guiding insertion rod 7 passing through the guiding channel 6. The partition component 8 is arranged in the guiding channel 6.

[0034] The clamping mechanism includes a horizontally arranged clamping frame 9, a movable clamping frame 10 and a control mechanism 11. The horizontally arranged clamping frame 9 is an L-shaped frame, and the long frame body of the horizontally arranged clamping frame 9 is arranged at the bottom end of the guiding insertion rod 7. The movable clamping frame 10 is rotatably installed on the horizontally arranged clamping frame 9, and the movable clamping frame 10 and the short frame body of the horizontally arranged clamping frame 9 form a clamping part. The control mechanism 11 is arranged on the horizontally arranged clamping frame 9 and the guiding insertion rod 7, and the control mechanism 11 acts on the movable clamping frame 10 to make the movable clamping frame 10 keep the tendency of rotating towards the short frame body part of the horizontally arranged clamping frame 9, and a clamping part of the clamp is formed by the movable clamping frame 10 and the short frame body of the horizontally arranged clamping frame 9.

[0035] Further, the control mechanism 11 includes an extrusion spring 1101, an outer pull rod 1102 and a control rod 1103. An installation cross plate is arranged on the long frame body of the horizontally arranged clamping frame 9. The extrusion spring 1101 is arranged on the installation cross plate, and the extrusion spring 1101 acts on the movable clamping frame 10 to make the movable clamping frame 10 keep the tendency of rotating towards the short frame body of the horizontally arranged clamping frame 9. One end of the outer pull rod 1102 is rotatably connected to the movable clamping frame 10, and the other end movably penetrates through the installation cross plate and is connected to the control rod 1103. The control rod 1103 is parallel to the guiding insertion rod 7, and the control rod 1103 passes through the limiting rubber sheet at the connection of the guiding insertion rod 7 and the guiding channel 6. The control rod 1103 can move towards the guiding insertion rod 7 side, thereby driving the outer pull rod 1102 to slide outwards, pulling the movable clamping frame 10 away from the short frame body of the horizontally arranged clamping frame 9 to open the clamping part. At this time, the output end of the atomization output component can be inserted into the socket of the guiding channel 6, and the edge of the output end is made to be close to the short frame body of the horizontally arranged clamping frame 9. Release the control rod 1103. Under the extrusion of the extrusion spring 1101, the movable clamping frame 10 rotates towards the short frame body part of the horizontally arranged clamping frame 9 to form a clamp on the edge of the output end of the atomization output component. At this time, the guiding insertion rod 7 can be pulled and multi-directionally rotated on the guiding channel 6 to guide the output end of the atomization output component inserted into the mask assembly to be close to the nasal cavity of the critically ill patient, facilitating the patient to inhale the atomized medicine.

[0036] Still further, a guiding block 12 is arranged on the long frame body of the horizontally arranged clamping frame 9. A guiding groove is opened on the guiding block 12, and the outer pull rod 1102 is attached to the inner wall of the guiding groove. Through the guiding and limiting of the outer pull rod 1102 by the guiding groove, it is convenient to control the outward sliding of the control rod 1103 and the outer pull rod 1102.

[0037] In this embodiment, the mask assembly is attached to the outside of the mouth and nose of a critically ill patient. When precise introduction of nebulized medicine is required, first pull the guiding insertion rod 7 and the clamping mechanism to slide outwards, so that the clamping mechanism approaches the socket of the guiding channel 6. At this time, press the control rod 1103 to move towards the guiding insertion rod 7, drive the outer pull rod 1102 to slide outwards, thereby pulling the movable clamping frame 10 away from the short frame body of the horizontally arranged clamping frame 9 to open the clamping part. Then insert the output end of the nebulizer output assembly into the socket of the guiding channel 6, make the edge of the output end close to the short frame body of the horizontally arranged clamping frame 9, and release the control rod 1103. Under the extrusion of the extrusion spring 1101, the movable clamping frame 10 rotates towards the short frame body part of the horizontally arranged clamping frame 9 to form a clamp on the edge of the output end of the nebulizer output assembly, so that the output end of the nebulizer output assembly forms a connection at the end of the guiding insertion rod 7. At this time, by controlling the insertion and multi-directional rotation of the guiding insertion rod 7 on the guiding channel 6, the output end of the nebulizer output assembly inserted into the mask assembly can be guided to be close to the nasal cavity of the critically ill patient. At this time, the nebulizer main body 501 can be started, and the nebulized medicine can be accurately introduced to the patient's nasal cavity through the output end of the nebulizer output assembly, which is convenient for the critically ill patient to inhale the nebulized medicine during shallow breathing.

[0038] Embodiment 2

[0039] As Figures 1-8 shown, this embodiment is basically the same as Embodiment 1. Preferably, in order to partition the internal space of the mask and reduce the space where the nebulized medicine is dispersed, and keep it as much as possible at the patient's respiratory tract to prevent excessive dispersion of the nebulized medicine, a partition assembly 8 is provided here, which includes an opening and closing partition board 801, a retraction spring 802 and a pressing side frame 803. The opening and closing partition board 801 is arranged at the center inside the mask assembly. The opening and closing partition board 801 includes two board bodies, and one of the board bodies is fixedly arranged on the inner side of the mask assembly, and the other board body is slidably installed on the fixed board body. The retraction spring 802 is arranged on the inner wall of the mask assembly, and the end of the retraction spring 802 is connected to the sliding board body, so that the sliding board body has a tendency to slide upwards and fit the fixed board body. Under normal conditions, the sliding board body fits the fixed board body, and at this time the opening and closing partition board 801 does not partition the gas space inside the mask assembly. The pressing side frame 803 is arranged on the sliding board body, and one end of the pressing side frame 803 is located directly below the guiding insertion rod 7, so that when the guiding insertion rod 7 moves downwards, it can squeeze the sliding board body to slide downwards, so that the sliding board body and the fixed board body can form a partition inside the mask assembly.

[0040] The mask assembly includes a plastic mask 13 and a locking band 14. The plastic mask 13 is a transparent mask. The guiding channel 6 is arranged on the outer wall of the plastic mask 13. There are two sockets on the guiding channel 6, and one of the sockets is connected to the hose of the ventilator main body 401. The locking band 14 is arranged at the edge of the plastic mask 13. The locking band 14 is a common elastic band and will not be elaborated here.

[0041] The atomization output component includes a diversion tube 15 and a sealing ring 16. One end of the diversion tube 15 is connected to the atomization main body 501. The diversion tube 15 is the output pipeline of the atomization output component. The diversion tube 15 is inserted into the socket of the guiding channel 6 and guided after being clamped by the clamping mechanism at the bottom end of the guiding rod 7. The sealing ring 16 is sleeved outside the diversion tube 15, and the sealing ring 16 is inserted into another socket of the guiding channel 6.

[0042] In this embodiment, when the guiding rod 7 is inserted and rotated in multiple directions in the socket of the guiding channel 6, as the guiding rod 7 moves downward, the sliding plate body part of the opening and closing partition plate 801 is squeezed by the guiding rod 7 and slides downward. At this time, the two plate bodies of the opening and closing partition plate 801 will form a partition inside the mask component, separating the patient's mouth and nasal cavity parts. When the clamping mechanism at the bottom end of the guiding rod 7 clamps the diversion tube 15 close to the patient's nasal cavity and introduces the atomized drug, the space where the atomized drug is dispersed in the mask component will be kept outside the nasal cavity part, allowing the atomized drug to stay as much as possible at the respiratory tract of the patient's nasal cavity, preventing the atomized drug from being overly dispersed, and adapting to the inhalation force of the patient's shallow breathing in the nasal cavity.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
