Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a nebulizer device for use during anesthesia. Background Technology

[0002] Anesthesia refers to the use of drugs or other methods to temporarily eliminate sensation in a patient, either whole or locally, to achieve pain-free surgical treatment. Commonly used general anesthesia methods during surgery include intravenous anesthesia and inhalation anesthesia, with inhalation anesthesia being particularly preferred. However, oxygen administration is often required concurrently with anesthesia. Currently, the oxygen tubing and the anesthetic nebulizer tubing are connected to a breathing mask, allowing oxygen and the nebulized anesthetic to simultaneously enter the patient's nasal cavity through the mask. This procedure can interfere with the inhalation of the anesthetic, thus affecting the effectiveness of the anesthesia. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use nebulizer for use during anesthesia. This nebulized anesthetic solution can be mixed with oxygen in a certain proportion and then supplied to the patient through a breathing mask, thus not affecting the inhalation of the anesthetic and ensuring the effectiveness of the anesthesia.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a housing, casters, and a liquid atomizer; casters are fixed at the four corners of the bottom wall of the housing, and a liquid atomizer is provided on one side of the top wall of the housing; the outlet of the liquid atomizer is connected to the housing via a pipe; it further comprises: The partition is located on the middle side inside the box, and the four sides of the partition are fixedly connected to the inner peripheral wall of the box. The pipe on the liquid atomizer is located on one side of the partition. The conveyor box is located on one side of the interior of the box, and a connecting pipe is inserted through one side wall of the conveyor box. The conveying mechanism is located inside the conveying box. A conveying pipe is inserted through the side wall of the conveying box away from the No. 1 connecting pipe, and a breathing mask is provided at the other end of the conveying pipe. A temporary storage box is located in front of the conveyor box. The rear side of the outer ring wall of the temporary storage box is connected to the front end of the No. 1 connecting pipe. Both the No. 1 connecting pipe and the conveyor pipe are equipped with one-way valves. The second connecting pipe has one end inserted through and into the side wall of the temporary storage box, and the other end inserted into the partition. The pump is embedded in the lower side of the partition. The outlet of the pump is connected to the end of the second connecting pipe away from the temporary storage box, and the inlet of the pump is connected to the other side of the partition through a pipe. The movable plate is located inside the temporary storage box, with its outer ring wall abutting against the inner ring wall of the temporary storage box, and the second connecting pipe located on the lower side of the movable plate. Two control switches are fixed on the upper and lower inner walls of the temporary storage box, respectively, and the control switches are connected to the pump. The control levers are two in number and are respectively fixed on the upper and lower side walls of the movable plate. The upper and lower control levers are arranged in the same vertical plane as the control switch. An oxygen generator is installed on one side of the top wall of the outer casing, and the outlet of the oxygen generator is connected to the interior of the casing through a pipe. A mixing mechanism is located on one side inside the housing, and is situated below the outlet of the oxygen generator and the liquid nebulizer. Through the above technical solution, the oxygen generator and the nebulizer draw oxygen and nebulized medication into the chamber, respectively, and are located on one side of the partition. The mixing mechanism is activated to mix the oxygen and medication. After mixing, the pump is activated to send the mixed gas into the storage box. At this time, the movable plate inside the storage box moves upward until it reaches the top of the storage box. The pump is then turned off, and the gas in the storage box is drawn into the breathing mask through the first connecting pipe and the delivery pipe via the delivery mechanism. This allows the patient to inhale both oxygen and anesthetic medication simultaneously. As the mixed gas in the storage box decreases, the movable plate moves downward, causing the control lever to move downward. When the control lever is pressed down against the control switch, the control switch activates the pump. The pump continues to draw the mixed gas from one side of the chamber into the storage box. This gas pushes the movable plate upward, causing the movable plate to move the control lever upward until the upper control lever touches the upper control switch. The upper control switch then turns off the pump, thus providing mixed gas to the storage box.

[0005] As a further improvement of the present invention, several telescopic rods are fixed at equal angles on the upper surface of the movable plate, and the upper ends of the telescopic rods are fixed to the inner top wall of the temporary storage box. The above technical solution can increase the stability of the movable plate during movement by using a telescopic rod.

[0006] As a further improvement of the present invention, the conveying mechanism includes: Piston plate, the piston plate is disposed on the lower side inside the conveying box, the piston plate is located on one side of the second connecting pipe and the first connecting pipe; A connecting plate is located in the middle of the inside of the conveyor box, and the lower side of the connecting plate is screwed to the upper side wall of the piston plate through a hinge seat. The drive plate consists of two drive plates, with their lower ends screwed to both sides of the connecting plate via shafts. A connecting shaft is fixed to the upper side of the drive plate away from the connecting plate, and the connecting shaft on one side is screwed to the inner wall of the conveyor box via a bearing. The conveyor motor is fixed on the inner wall of the other side of the conveyor box. The conveyor motor is connected to an external power source, and the output shaft of the conveyor motor is fixedly connected to the connecting shaft on the other side. The above technical solution involves starting a conveyor motor, which drives a connected shaft to rotate. This connected shaft then drives a drive plate to rotate. As the drive plate rotates, it causes the connecting plate to move up and down. The connecting plate then causes a piston plate to move up and down. As the piston plate moves up and down, it draws the mixed gas through a first connecting pipe and then sends it into the conveyor pipe, thereby achieving efficient conveying.

[0007] As a further improvement of the present invention, a winding rod is fixed on one side of the top wall of the inner box, and the conveying pipe is wound around the winding rod; The above technical solution allows excess conveying pipes to be stored by winding around a rod, preventing the pipes from bending.

[0008] As a further improvement of the present invention, a protective frame is fixed on the outer wall of one side of the box, and a cover plate is screwed to the outer side of the protective frame by a hinge. A disinfection lamp is fixed on the inner wall of the cover plate, the breathing mask is located inside the protective frame, and the delivery tube is inserted through the side wall of the box located inside the protective frame. With the above technical solution, the breathing mask remains inside the protective frame when not in use, and is continuously disinfected by a disinfection lamp, making it convenient to use.

[0009] As a further improvement of the present invention, the mixing mechanism includes: The movable plate is located inside the box on the side away from the temporary storage box. The outer peripheral wall of the movable plate abuts against the inner side wall of the box and the partition. Several ventilation holes are arranged in a matrix on the movable plate. A reciprocating lead screw is threaded onto one side of a moving plate. The front and rear ends of the reciprocating lead screw are respectively threaded onto the front and rear inner walls of the housing through sealed bearings. A guide rod passes through the other side of the moving plate, and the front and rear ends of the guide rod are respectively fixedly connected to the front and rear inner walls of the housing. The hybrid motor is fixed on the outer wall of the front side of the housing. The hybrid motor is connected to an external power source. The output shaft of the hybrid motor is inserted into the front wall of the housing. The output shaft of the hybrid motor is fixedly connected to the front end of the reciprocating lead screw. The dual-axis motor consists of two motors, which are symmetrically embedded in the moving plate. A stirring rod is fixed on the output shaft on both sides of the dual-axis motor. The outer end of the stirring rod passes through the side wall of the moving plate and is exposed on the outside of the moving plate. The stirring blades are a plurality of blades, which are fixed equally and at equal angles on the outer ring wall of the stirring rod. The above technical solution involves starting a mixing motor, which drives a reciprocating screw to rotate. The reciprocating screw then drives a moving plate to move back and forth. During this movement, the moving plate allows gas to pass through several vent holes. Simultaneously, a dual-axis motor is started, which drives a stirring rod to rotate. The stirring rod then drives a stirring blade to rotate, thereby mixing oxygen and the atomized anesthetic solution through the stirring blade.

[0010] As a further improvement of the present invention, several heating rods are equidistantly embedded on both sides of the movable plate from left to right, and the heating rods are connected to an external power source. Through the above technical solution, the moving plate heats the mixed gas through a heating rod during the movement process, avoiding the gas temperature being too low and causing adverse effects on the patient.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The chamber is divided by partitions, and oxygen and nebulized anesthetic solution are mixed on one side after the partition, so that oxygen and anesthetic solution can be supplied to the patient at the same time, which improves the anesthetic effect. 2. The mixed gas is pumped into the temporary storage tank by the pump, and the pump can be controlled according to the amount of gas in the temporary storage tank during use, so as not to affect the mixing of the gas.

[0021] See Figure 2 , Figure 4 As shown, based on Embodiment 1, the mixing mechanism 15 includes: The movable plate 15-1 is located inside the housing 1 on the side away from the temporary storage box 8. The outer peripheral wall of the movable plate 15-1 abuts against the inner side wall of the housing 1 and the partition 4. Several ventilation holes 15-1-1 are opened in a matrix on the movable plate 15-1. Several heating rods 21 are embedded from left to right on both sides of the movable plate 15-1. The heating rods 21 are connected to an external power source. The reciprocating screw 15-2 is threaded to the right side of the moving plate 15-1.
