Description

Universal respirator tube
Technical Field
The invention relates to the field of respirators, in particular to a universal respirator tube.
Background
There are two types of breathing machines, namely a fixed breathing machine and a portable breathing machine.
The fixed breathing machine is placed in a ward for use, and has a more complex structure and more functions. The pipeline of the existing fixed respirator is shown in fig. 1 and comprises an air inlet filter, an air outlet filter, a three-way connector, an air inlet branch and an air outlet branch; three joints of the three-way connector are respectively an air inlet joint, an air outlet joint and an external joint; the air inlet branch comprises a first air inlet pipe, a humidifying tank, a second air inlet pipe, a first condensation water cup and a third air inlet pipe which are sequentially arranged and connected; a second condensation water cup is arranged on the air outlet branch; the air inlet branch is connected with the air inlet filter and the air inlet joint, and the air outlet branch is connected with the air outlet filter and the air outlet joint.
When in use, the air inlet filter and the air outlet filter are respectively connected with the output interface and the input interface of the respirator, and the external connector is connected with the tracheotomy tube, the oxygen mask and the like. The breathing machine outputs gas through the output interface, enters the air inlet branch, is purified by the air inlet filter, is humidified and heated by the humidifying tank, and is input into a human body. The gas exhaled by the human body enters the gas outlet branch, is purified by the gas outlet filter and enters the breathing machine through the input interface. The condensation water cup is used for collecting condensation water in the pipeline. The pressure and flow data of the air supply of the respirator are measured and displayed in the respirator.
The portable respirator is used when a patient is transported, and has lighter weight and smaller volume, so the structure is simplified and the functions are reduced; the piping is correspondingly different. The existing portable respirator and the pipeline thereof are shown in figure 2, the pipeline of the portable respirator is not provided with an air outlet branch, a humidification tank and a condensation water cup, and is only provided with an air inlet filter, an air inlet branch, a tee joint and an air outlet filter. The gas exhaled by human body is directly discharged after being filtered.
The portable respirator has the advantages that the structure is simplified, the functions are reduced, and a valve is required to be arranged in the three-way joint for controlling gas to enter and exit, so that the phenomenon that the inhaled quantity of a patient is small due to the fact that a large amount of gas is directly discharged is avoided, and the phenomenon that exhaled gas enters the air inlet branch is avoided. In addition, portable ventilators often require the use of measurement lines, connected as shown in fig. 2, for transmitting pressure and flow signals to the portable ventilator.
Because of the difference of the two breathing machines, the pipelines of the two breathing machines can not be used universally at present, the patient needs to buy the two pipelines, the cost of the pipelines of the breathing machines is low, and the burden of the patient is increased. After the patient is discharged, the two breathing machine pipelines need to be discarded, so that medical waste is increased, and the environment is not protected.
In addition, the principle of the humidifying tank of the breathing machine is that the humidifying tank is heated by the breathing machine, so that water in the humidifying tank is evaporated quickly, and the water vapor is mixed with the gas to humidify and heat the gas. The humidifying tank consumes water quickly and has requirements on water level, and can not directly store more water, so that water needs to be supplemented at any time to maintain the water level. At present, the mode of water supplement of the humidification tank is similar to infusion, namely a water supplement bottle is used for hanging, a pipeline is connected with the humidification tank and the water supplement bottle, a controller is arranged in the humidification tank, water enters when the water level is reduced, and the water level reaches the standard and then the water is prevented from entering.

Aiming at the problem of water replenishing of the existing humidification tank 3-2, the invention is further improved as shown in figures 8 and 9: the humidifying tank 3-2 comprises a tank body 3-2-1, a water container 3-2-2, a water inlet pipe 3-2-3 and a water level controller 3-2-4; the water container 3-2-2 is annular, the water container 3-2-2 is provided with a water adding port 3-2-1 and a breathing port 3-2-2-2, the water container 3-2-2 is sleeved outside the tank body 3-2-1 and is connected with the tank body 3-2-1, the bottom surface of the water container 3-2-2 is higher than the bottom surface of the tank body 3-2-1, the water inlet pipe 3-2-3 is communicated with the water container 3-2-2 and the tank body 3-2-1, and the water inlet pipe 3-2-3 comprises a water outlet head 3-2-3-1 which is positioned in the tank body 3-2-1 and faces downwards; the water level controller 3-2-4 is positioned below the water inlet pipe 3-2-3, the water level controller 3-2-4 comprises a swing rod 3-2-4-2, a floater 3-2-4-3 and a sealing sheet 3-2-4-1, one end of the swing rod 3-2-4-2 is hinged with the tank body 3-2-1, the other end of the swing rod is connected with the floater 3-2-4-3, and the sealing sheet 3-2-4-1 is connected with the swing rod 3-2-4-2 and corresponds to the position of a water outlet head 3-2-3-1.
Thus, the water filling port 3-2-2-1 is opened, water is firstly added into the water container 3-2-2, and the water enters the tank body 3-2-1 through the water inlet pipe 3-2-3. The floater 3-2-4-3 floats up due to the water entering, and the swinging rod 3-2-4-2 is driven to swing upwards. When enough water is available, the sealing sheet 3-2-4-1 seals the water outlet head 3-2-3-1, and water can not enter the tank body 3-2-1 any more. After the water in the tank body 3-2-1 is consumed, the floater 3-2-4-3 moves downwards, the sealing sheet 3-2-4-1 does not seal the water outlet head 3-2-3-1, and the water enters the tank body 3-2-1 again. Thus, the water level of the tank body 3-2-1 can be automatically kept basically constant.
The bottom of the water container 3-2-2 is higher than the specified water level of the tank body 3-2-1 to ensure that the water in the water container 3-2-2 can flow into the tank body 3-2-1 by the self gravity.
The temperature of water in the tank body 3-2-1 is 50-70 ℃, and in order to avoid that the water container 3-2-2 is influenced by the temperature of the water and the water container 3-2-2 is accelerated to evaporate, the following settings can be made: the water container 3-2-2 is separated from the tank body 3-2-1, and the water container 3-2-2 is connected with the tank body 3-2-1 through a connecting strip 3-2-5. Thus, the heat conduction between the tank body 3-2-1 and the water container 3-2-2 can be reduced. An insulating pad may be further provided between the can body 3-2-1 and the water container 3-2-2 to further reduce heat transfer.
In case of a patient suffering from an infectious disease, such as the new coronary pneumonia that currently exists, the exhalation filter 2 should be a filter capable of filtering viruses in order to avoid viral shedding.
The amount of carbon dioxide exhaled by a patient can reflect pulmonary conditions, and therefore carbon dioxide detection is of great clinical significance. The portable ventilator 9 cannot detect carbon dioxide because the outlet air does not enter the ventilator. At present, although a carbon dioxide detector exists, the structure is complex and cannot be used as a part of a respirator tube. Therefore, the simple carbon dioxide detector 12 is designed, and the cost is low, and the simple carbon dioxide detector can be used as a part of a breathing machine pipe and can also be used independently.
The carbon dioxide detector 12 comprises a detector main pipe 12-1, an air bag 12-4, a detection pipe 12-10, a detection pipe air pipe 12-8, a porous air distribution disc 12-11, a first detection branch pipe 12-3, a second detection branch pipe 12-5, a third detection branch pipe 12-7 and a PH contrast color card 12-9; a gas pipe 12-8 of the detection pipe extends into the detection pipe 12-10 and is connected with the detection pipe 12-10, a porous gas distribution disc 12-11 is positioned at the bottom of the detection pipe 12-10 and is connected with the gas pipe 12-8 of the detection pipe, and detection solution is arranged in the detection pipe 12-10; the air bag 12-4 is connected with the detector main pipe 12-1 through a first detection branch pipe 12-3, and a switch 12-2 is arranged on the first detection branch pipe 12-3; the air bag 12-4 is connected with the air pipe 12-8 of the detection pipe through a second detection branch pipe 12-5, a check valve 12-6 is arranged on the second detection branch pipe 12-5, a third detection branch pipe 12-7 is connected with the detection pipe 12-10 and the main pipe 12-1 of the detector, a check valve 12-6 is arranged on the third detection branch pipe 12-7, and a PH contrast color card 12-9 is attached to the detection pipe 12-10; when the general-purpose respirator pipe is in the second use state, the main detector pipe 12-1 is connected with the air outlet filter 2.
Wherein the detection solution is an existing solution for detecting the pH value, and the invention is preferably a bromothymol blue solution.
The carbon dioxide detector 12 operates on the following principle: the gas exhaled by the patient passes through the main detector tube 12-1 and is exhausted, and part of the gas is stored in the air bag 12-4. When carbon dioxide needs to be detected, the switch 12-2 is closed, the air bag 12-4 is extruded, gas stored in the air bag 12-4 enters the porous gas distribution plate 12-11 through the first detection branch pipe 12-3 and the detection pipe air pipe 12-8, a plurality of small holes are formed in the porous gas distribution plate 12-11, and the gas forms a plurality of small bubbles after passing through the porous gas distribution plate 12-11, so that the carbon dioxide is dissolved into a detection solution. The carbon dioxide dissolves into the test solution to produce carbonic acid which changes the color of the test solution, and the amount of carbon dioxide in the patient's exhaled breath can be approximated by comparing the color of the test solution to the pH contrasting color card 12-9.
The two one-way valves 12-6 function to prevent the test solution from leaking out without affecting the gas flow. The one-way valve 12-6 is preferably an existing one-way valve. Preferably, the lower surface of the porous gas distribution plate 12-11 is spaced a small distance from the bottom surface of the inner space of the sensing tube 12-10, and the edge of the porous gas distribution plate 12-11 is attached or connected to the sensing tube 12-10. Therefore, the gas enters a narrow space between the porous gas distribution plate 12-11 and the bottom of the detection tube 12-10 to form small bubbles which are upward, and meanwhile, the upward gas cannot expand to the periphery until passing through the surrounding dense mesh holes, so that the generation of large bubbles is avoided, and the solubility is increased. The components of the carbon dioxide detector 12 are preferably detachable to facilitate disassembly for cleaning and disinfection, as well as filling and emptying of the detection solution.
The temperature of the patient's inhaled air and the humidity of the exhaled air are also important parameters, for which the following settings can be made: the universal respirator tube comprises a temperature detection patch 13 and a humidity detection piece 14, wherein the temperature detection patch 13 is attached to the inner surface of the third air inlet tube 3-5, and the humidity detection piece 14 is clamped on the inner surface of the air outlet connector 5-3. The third air inlet pipe 3-5 and the air outlet joint 5-3 should be transparent at the positions corresponding to the temperature detection patch 13 and the humidity detection patch 14 for easy observation. The temperature detection patch 13 and the humidity detection patch 14 are prior art products. The temperature detection patch 13 and the humidity detection patch 14 are used for detecting the temperature of the inhaled air and the humidity of the exhaled air, and the cost is low.
