[0004] However, the current monitoring device has the following problems: the monitoring device is not convenient for delivering oxygen according to the quality of oxygen. When the oxygen quality is good, excessive oxygen processing will affect the overall efficiency of gas monitoring. If the oxygen quality is already good enough, continuing to remove water may not only have no additional effect, but may also reduce the overall working efficiency of the system and add unnecessary processing steps. Therefore, we propose a medical gas monitoring device. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a medical gas monitoring device that solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a medical gas monitoring device, including a device body, an oxygen analyzer is fixed on the top of the device body, a U-shaped tube is fixed to the gas outlet of the oxygen analyzer, a processing device is provided at the gas outlet end of the U-shaped tube, and the processing device includes a tee, the tee is fixed to the gas outlet end of the U-shaped tube, a circular shell is fixed to the lower horizontal branch of the tee, and the end of the circular shell away from the lower horizontal branch of the tee is connected to the upper horizontal branch of the tee through an L-shaped tube.

When the oxygen analyzer monitors and analyzes that the oxygen quality is poor, the staff rotates the screw, and the screw is acted upon by the threads of the U-shaped frame, and the screw moves upward, and the screw drives the plug disc to move upward until the plug disc blocks the upper horizontal branch of the tee.

[0007] According to the above technical solution, the water removal component includes two mounting plates, a number of adsorption cottons, a number of partitions, a number of condensing tubes, and a refrigerator. The refrigerator is fixed to the bottom of the circular shell, a number of the condensing tubes are fixed to both sides of the top of the refrigerator, and the condensing tubes are located inside the circular shell, a number of the partitions are respectively fixed to the bottom of the inner wall on both sides of the circular shell, a number of the partitions are located between two adjacent partitions, a number of the partitions on one side are staggered, and a number of partitions on one side form an S-shaped channel, the two mounting plates are respectively fixed to both sides of the outer wall of the circular shell by bolts, a number of the adsorption cottons are evenly and equidistantly fixed on the side close to each other of the two mounting plates, a number of the adsorption cottons are respectively located on both sides of a number of partitions, when oxygen passes through the lower horizontal branch of the tee pipe, the refrigerator is started, and the refrigerator will cool the condensing tube, when oxygen passes through the condensing tube, the condensing tube will pre-condense and remove the moisture in the oxygen, and when oxygen passes through the adsorption cotton, the adsorption cotton will adsorb impurities in the oxygen.

[0008] According to the above technical solution, a switching device is provided at the circular shell, and the switching device includes a baffle and an electric reciprocating push rod, and the baffle is slidably installed inside the circular shell, and square rods are fixed on both sides of the baffle, and the square rods horizontally penetrate the inner wall of the circular shell, the fixed end of the electric reciprocating push rod is fixed to the bottom of the circular shell, and the fixed end of the electric reciprocating push rod is fixed to a connecting rod, and the end of the connecting rod away from the electric reciprocating push rod is fixedly connected to the square rod on one side. When the oxygen analyzer monitors and analyzes that the oxygen quality is good, the oxygen will be discharged through the upper horizontal branch of the three-way pipe, the telescopic end of the electric reciprocating push rod drives the connecting rod to move back and forth, and the connecting rod drives the square rod on one side to move back and forth, and the square rod drives the baffle to move back and forth along the inside of the circular shell. Each time the baffle moves along one side of the inside of the circular shell, when the baffle moves to the L-shaped plate, the baffle and the L-shaped plate will block one side opening of the circular shell. At this time, the adsorption cotton and condensation tube on the other side work.

[0009] According to the above technical solution, the switching device also includes two slides, two fixed blocks, two positioning rods, and two fixed plates. The two fixed blocks are respectively fixed on both sides of the top of the circular shell. The two slides are respectively penetrated and slidably installed on both sides of the circular shell. The two positioning rods are respectively fixed on the top of the two slides. The positioning rods penetrate the fixed blocks, and a spring is provided between the positioning rods and the fixed blocks. Several extrusion plates are evenly and equidistantly fixed on the bottom of the side where the two slides are close to each other. The extrusion plates are in contact with the side of the adsorption cotton away from the mounting plate. The two fixed plates are respectively fixed on the inner side of the circular shell. On both sides of the wall, an L-shaped plate is slidably installed on the outside of the two fixed plates, and a spring is provided between the L-shaped plate and the inner wall of the circular shell. The top of the L-shaped plate is fixedly connected to the bottom of the slide plate, and the middle of the L-shaped plate is provided with a groove for accommodating the square rod. The L-shaped plate is located on the movement trajectory of the extrusion plate. As the baffle continues to move, the baffle will push the L-shaped plate to move along the outer wall of the fixed plate toward the inner wall of the circular shell. The L-shaped plate drives the slide plate to move, and the slide plate drives the positioning rod to move. The spring corresponding to the positioning rod is compressed, and the slide plate drives the extrusion plate to move, and the extrusion plate squeezes the adsorption cotton.

[0010] According to the above technical solution, a water collecting device including a collecting box and two L-shaped rods is provided below the circular shell. The collecting box is fixed to the bottom of the inner wall of the circular shell. L-shaped water collecting pipes are fixed on both sides of the top of the collecting box. The top of the cross-bracing rod of the L-shaped water collecting pipe is connected to the bottom of the circular shell through a number of pipes. The two L-shaped rods are respectively passed through and slidably installed on both sides of the bottom of the circular shell. The top of the L-shaped rod is hingedly connected to the outer wall of the L-shaped plate through a hinged rod. A connecting plate is fixed to the outer wall below the L-shaped rod. A number of blocking columns are evenly and equidistantly fixed on the top of the connecting plate, and the blocking columns are fixed to the top of the connecting plate.

Every time the L-shaped plate moves along the outer wall of the fixed plate toward the inner wall of the circular shell, the L-shaped plate pushes the hinged rod to drive the L-shaped rod to move downward, and the L-shaped rod drives the connecting plate and the blocking column to move downward. The blocking column no longer blocks the pipe corresponding to the horizontal support rod of the L-shaped water collecting pipe.

[0011] The present invention provides a medical gas monitoring device having the following beneficial effects:

[0012] (1) The present invention sets up a condensing device. When the oxygen analyzer monitors and analyzes that the oxygen quality is poor, the screw and the U-shaped frame cooperate to drive the plug disc to block the upper horizontal branch of the three-way pipe. The oxygen will be discharged through the lower horizontal branch of the three-way pipe and dehydrated and impurities will be removed, thereby avoiding excessive oxygen treatment that will affect the overall efficiency of gas monitoring. When the oxygen passes through the lower horizontal branch of the three-way pipe, the refrigerator and the condenser cooperate to pre-condense and remove the moisture in the oxygen. When the oxygen passes through the adsorption cotton, the adsorption cotton will adsorb impurities in the oxygen, and the adsorption cotton will adsorb moisture on the surface of the condenser. At the same time, the S-shaped channel formed by several partitions increases the formation of oxygen passing through the condenser and the adsorption cotton, thereby improving the effect of the condenser on pre-condensing and removing moisture in the oxygen and the adsorption cotton on adsorbing impurities in the oxygen.

[0013] (2) The present invention sets a switching device so that the electric reciprocating push rod and the connecting rod cooperate to drive the baffle and the L-shaped plate to block the opening on one side of the circular shell. At this time, the adsorption cotton and the condensation tube on the other side work. By switching the adsorption cotton and the condensation tube on both sides of the circular shell to work alternately, the gas monitoring operation is ensured to run effectively without the efficiency being reduced due to the excessive use of a certain group of adsorption cotton and condensation tube; at the same time, the baffle, L-shaped plate, fixed plate, circular shell, and positioning rod cooperate to drive the extrusion plate to extrude the adsorption cotton, and the moisture adsorbed by the adsorption cotton is squeezed out, which is conducive to the sustainable use of the adsorption cotton.

[0014] (3) The present invention sets a water collecting device. Each time the L-shaped plate moves along the outer wall of the fixed plate toward the inner wall of the circular shell, the L-shaped plate, the hinged rod, the L-shaped rod, and the connecting plate cooperate to drive the blocking column to no longer block the pipe corresponding to the cross support rod of the L-shaped water collecting pipe. At this time, the water squeezed out of the adsorption cotton can enter the L-shaped water collecting pipe through the drainage hole of the circular shell, and the L-shaped water collecting pipe will transmit the water to the collection box for collection.

At this time, the adsorption cotton 48 and the condenser 410 on the other side work. By switching the adsorption cotton 48 and the condenser 410 on both sides of the circular shell 42 to work, the gas monitoring operation is ensured to run effectively without causing a decrease in efficiency due to excessive use of a certain group of adsorption cotton 48 and condenser 410.

[0027] The switching device 5 also includes two slides 51, two fixed blocks 52, two positioning rods 53, and two fixed plates 59. The two fixed blocks 52 are respectively fixed to the top two sides of the circular shell 42. The two slides 51 pass through and are slidably installed on both sides of the circular shell 42. The two positioning rods 53 are respectively fixed to the top of the two slides 51. The positioning rods 53 pass through the fixed blocks 52, and a spring is provided between the positioning rods 53 and the fixed blocks 52. A plurality of extrusion plates 54 are evenly and equidistantly fixed to the bottom of the side where the two slides 51 are close to each other.

[0028] A water collecting device 6 is provided below the circular shell 42, including a collecting box 62 and two L-shaped rods 63. The collecting box 62 is fixed to the bottom of the inner wall of the circular shell 42. L-shaped water collecting pipes 61 are fixed on both sides of the top of the collecting box 62. The top of the horizontal support rod of the L-shaped water collecting pipe 61 is connected to the bottom of the circular shell 42 through a number of pipes. The two L-shaped rods 63 are respectively passed through and slidably installed on both sides of the bottom of the circular shell 42.

Through the arrangement of the above structure, the blocking columns 66 no longer block the pipes corresponding to the horizontal support rods of the L-shaped water collecting pipe 61. At this time, the water squeezed out from the adsorption cotton 48 can enter the L-shaped water collecting pipe 61 through the drainage holes of the circular shell 42, and the L-shaped water collecting pipe 61 will transfer the water to the collection box 62 for collection.

[0029] During use, the air inlet end of the oxygen analyzer 2 is connected to the external oxygen tank, and the external oxygen tank will transport oxygen to the oxygen analyzer 2, which will monitor and analyze the quality of the oxygen. Then, the air outlet end of the oxygen analyzer 2 will transmit the oxygen to the inside of the three-way pipe 41 through the U-shaped tube 3. When the oxygen analyzer 2 monitors and analyzes that the oxygen quality is good, the oxygen will be discharged through the upper horizontal branch of the three-way pipe 41. When the oxygen analyzer 2 monitors and analyzes that the oxygen quality is poor, the staff will rotate the screw 45. The screw 45 is affected by the thread of the U-shaped frame 44, and the screw 45 will move upward. The screw 45 drives the plug disc 46 to move upward until the plug disc 46 blocks the upper horizontal branch of the three-way pipe 41. At this time, the oxygen will be discharged through the lower horizontal branch of the three-way pipe 41 and dehydrated. Impurity removal operation is carried out, thereby avoiding excessive oxygen processing that will affect the overall efficiency of gas monitoring; when oxygen passes through the lower horizontal branch of the three-way pipe 41, the refrigerator 411 is started, and the refrigerator 411 will cool the condenser 410. When the oxygen passes through the condenser 410, the condenser 410 will pre-condense and remove the moisture in the oxygen. When the oxygen passes through the adsorption cotton 48, the adsorption cotton 48 will adsorb impurities in the oxygen, and the adsorption cotton 48 will adsorb moisture on the surface of the condenser 410. At the same time, the S-shaped channel formed by several partitions 49 increases the formation of oxygen passing through the condenser 410 and the adsorption cotton 48, thereby improving the effect of the condenser 410 pre-condensing and removing moisture in the oxygen and the adsorption cotton 48 adsorbing impurities in the oxygen.

[0030] At the same time, the electric reciprocating push rod 56 is started, and the telescopic end of the electric reciprocating push rod 56 drives the connecting rod 58 to move back and forth, and the connecting rod 58 drives the square rod 57 on one side to move back and forth, and the square rod 57 drives the baffle 55 to move back and forth along the inside of the circular shell 42. Each time the baffle 55 moves along one side of the inside of the circular shell 42, when the baffle 55 moves to the L-shaped plate 510, the baffle 55 and the L-shaped plate 510 will block one side opening of the circular shell 42. At this time, the adsorption cotton 48 and the condensation tube 410 on the other side work. By switching the adsorption cotton 48 and the condensation tube 410 on both sides of the inside of the circular shell 42 to work, the gas monitoring operation is ensured to run effectively, and the efficiency will not be reduced due to the excessive use of a certain group of adsorption cotton 48 and condensation tube 410; as the baffle 55 continues to move, the baffle 55 will push the L-shaped plate 510 along the fixed The outer wall of the plate 59 moves toward the inner wall of the circular shell 42, and the L-shaped plate 510 drives the slide plate 51 to move, and the slide plate 51 drives the positioning rod 53 to move. The spring corresponding to the positioning rod 53 is compressed, and the slide plate 51 drives the extrusion plate 54 to move. The extrusion plate 54 squeezes the adsorption cotton 48, and the water adsorbed by the adsorption cotton 48 is squeezed out, which helps to sustain the use of the adsorption cotton 48. It should be noted that when the baffle 55 does not push the L-shaped plate 510, the L-shaped plate 510 will be reset by the corresponding spring, and the slide plate 51 will be reset by the spring corresponding to the positioning rod 53. It should also be noted that when the adsorption cotton 48 on one side is squeezing water, the adsorption cotton 48 on the other side is in normal working condition. By squeezing water from the adsorption cotton 48 in this way, the efficiency of the oxygen analyzer 2 in monitoring and analyzing the quality of oxygen is indirectly improved.

[0031] Each time the L-shaped plate 510 moves along the outer wall of the fixed plate 59 toward the inner wall of the circular shell 42, the L-shaped plate 510 pushes the hinged rod 64 to drive the L-shaped rod 63 to move downward, and the L-shaped rod 63 drives the connecting plate 65 and the blocking column 66 to move downward. The blocking column 66 no longer blocks the pipe corresponding to the cross rod of the L-shaped water collecting pipe 61. At this time, the water squeezed out from the adsorption cotton 48 can enter the L-shaped water collecting pipe 61 through the drainage hole of the circular shell 42, and the L-shaped water collecting pipe 61 will transfer the water to the collection box 62 for collection. It should be noted that the process in which the blocking column 66 no longer blocks the L-shaped water collecting pipe 61 will only be triggered when the baffle 55 and the L-shaped plate 510 block the opening on one side of the circular shell 42.
