Description

Technical Field

[0001] The invention belongs to the technical field of gas humidification, and specifically refers to a gas humidification device for a clinical critical care ventilator. Background Art

[0002] Active humidification is achieved through a heated humidifier. This type of humidifier is usually connected to the inhalation pipeline and consists of a humidification tank, a heating device, a power cord, a temperature sensor and other components. The principle of an active humidifier is to heat sterile distilled water to produce water vapor, which is then mixed with the inhaled gas to heat and humidify the inhaled gas.

[0003] The existing gas humidification devices for ventilators have the following problems: In the process of heating to generate steam, the existing gas humidifier for ventilator has a liquid level that continues to drop as the liquid evaporates, which increases the distance between the steam source and the oxygen supply pipe, causing the steam to change into condensed water when flowing through the pipe, thereby reducing the humidification effect of oxygen. In addition, the traditional gas humidifier for ventilator needs to constantly adjust the heating temperature to prevent the steam from changing into condensed water during the circulation process. The operation is cumbersome and complicated. Therefore, it cannot meet the existing use requirements of gas humidifiers for clinical critical care ventilators. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a gas humidification device for clinical critical care ventilators, which can always maintain the distance between the steam source and the oxygen supply pipeline without changing the heating temperature, thereby reducing the probability of steam changing into condensed water.

[0005] The technical scheme adopted in this scheme is as follows: This scheme proposes a gas humidification device for a clinical critical care ventilator, comprising a heating seat, a heating box, an induction-type water injection mechanism and a heat distillation mechanism, wherein the heating box is arranged on the upper wall of the heating seat, the induction-type water injection mechanism is arranged on the heating box, the heat distillation mechanism is arranged on one side of the heating box, the induction-type water injection mechanism comprises a liquid storage mechanism, a liquid measuring mechanism and an oblique flow mechanism, the liquid storage mechanism is arranged inside the heating box, the liquid measuring mechanism is arranged on the side wall of the heating box, the oblique flow mechanism is arranged at one end of the heating box close to the liquid measuring mechanism, the heat distillation mechanism comprises a supporting mechanism and a heating mechanism, the supporting mechanism is arranged on the bottom side wall of the heating box, and the heating mechanism is arranged on the supporting mechanism.

[0006] As a further preferred embodiment of the present invention, the liquid storage mechanism includes a one-way water injection valve, a fixed plate, a sliding copper plate and a copper spring. The one-way water injection valve is connected and arranged on the upper wall of the heating box, the fixed plate is arranged on the bottom wall of the heating box, the sliding copper plate is slidably arranged on the inner wall of the heating box, and multiple groups of the copper springs are arranged between the fixed plate and the sliding copper plate; the liquid measuring mechanism includes a groove, a sensing block and a proximity switch. The groove is symmetrically arranged on both sides of the sliding copper plate, and the groove is open at one end. The sensing block is arranged on the inner wall of the groove, and the proximity switch is symmetrically arranged on both sides of the top of the heating box; the oblique flow mechanism includes a transparent channel, a steam pipe and a connecting head. The transparent channel is symmetrically arranged on the side wall of the heating box above the proximity switch, the transparent channel is connected to the heating box, the steam pipe is connected and arranged on the side of the transparent channel away from the heating box, and the connecting head is connected and arranged on the side of the steam pipe away from the transparent channel.

[0007] When in use, open the one-way water injection valve, and sterile distilled water enters the heating box through the one-way water injection valve. In the initial state, the copper spring is in an extended setting, and the sterile distilled water falls onto the upper wall of the sliding copper plate. The weight of the sliding copper plate increases, and the copper spring uses its own deformation to drive the sliding copper plate to slide down along the inner wall of the heating box. After the sterile distilled water enters the middle position of the transparent channel, the water injection into the heating box is stopped.

[0008] Preferably, the supporting mechanism comprises a supporting frame, a heat source tube and a heat conducting port, the supporting frame is symmetrically arranged on the bottom side wall of the heating box, the heat source tube is arranged on the side of the supporting frame away from the heating box, and multiple groups of heat conducting ports are arranged on the side of the heat source tube close to the supporting frame; the heating mechanism comprises a heating sleeve, a heating copper rod, a high-frequency coil, a metal rod, a thermal insulation coating and a temperature sensor, multiple groups of the heating sleeves are arranged through the bottom inner wall of the heating box, the heating sleeve and the heat conducting port are arranged coaxially and horizontally, the heating copper rod is arranged between the inner wall of the heating sleeve and the inner wall of the heat conducting port, the heating copper rod is arranged on the inner wall of the heat source tube, the metal rod is arranged on the inner wall of the heating sleeve, the high-frequency coil is arranged on the inner wall of the heating sleeve outside the metal rod, the thermal insulation coating is arranged on the side wall of the heating copper rod, the temperature sensor is arranged on the upper wall of the heating box, and the detection end of the temperature sensor is arranged through the inside of the heating box.

[0009] When in use, the one-way water injection valve is manually closed, and the high-frequency coil performs high-frequency induction on the metal rod. The temperature of the metal rod rises to heat the inside of the heating sleeve. The temperature inside the heating sleeve enters the heating box under the conduction of the heating copper rod. The temperature inside the heating box close to the end of the heating copper rod rises, and the heat inside the heating box is conducted to the sliding copper plate and the copper spring. The sliding copper plate heats the sterile distilled water on its upper wall. The temperature sensor monitors the heating temperature of the sterile distilled water in real time through the detection end. The thermal insulation coating insulates the heat inside the heating copper rod to reduce heat loss. The sterile distilled water inside the heating box generates steam after heating. The steam enters the steam pipe through a transparent channel. The connector is connected to the oxygen supply pipe of the ventilator. The steam enters the oxygen supply pipe of the ventilator through the connector and mixes with oxygen to humidify the oxygen.

[0010] Specifically, a controller is provided on the side wall of the heating box.

[0011] Wherein, the controller is electrically connected to the proximity switch, the high-frequency coil and the temperature sensor respectively.

[0012] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a liquid-filled channel instead of a steam pipe. By setting up an induction-type water injection mechanism and a heat distillation mechanism, and by using the liquid storage mechanism, the liquid measuring mechanism, the oblique flow mechanism, the supporting mechanism and the heating mechanism in coordination with each other, the distance between the heating source and the oxygen supply pipe can be shortened, the loss of heat inside the steam can be reduced, and the probability of steam changing into condensed water when circulating in the oxygen supply pipe can be reduced, thereby ensuring the supply humidity of oxygen. The temperature sensor monitors the heating temperature of the sterile distilled water in real time through the detection end, and the thermal insulation coating insulates the heat inside the heating copper rod to reduce heat loss. The sterile distilled water inside the heating box generates steam after heating, and the steam enters the steam pipe through the transparent channel. The connector is connected to the oxygen supply pipe of the ventilator, and the steam enters the oxygen supply pipe of the ventilator through the connector to mix with the oxygen to humidify the oxygen.

The one-way water injection valve 5 is connected to the upper wall of the heating box 2, the fixed plate 6 is arranged on the bottom wall of the heating box 2, the sliding copper plate 7 is slidably arranged on the inner wall of the heating box 2, and multiple groups of the copper springs 8 are arranged between the fixed plate 6 and the sliding copper plate 7; the liquid measuring mechanism 9 includes a groove 10, a sensor block 11 and a proximity switch 12, the groove 10 is symmetrically arranged on both sides of the sliding copper plate 7, and the groove 10 is open at one end.

[0020] The support mechanism 18 includes a support frame 19, a heat source tube 20 and a heat conduction port 21. The support frame 19 is symmetrically arranged on the bottom side wall of the heating box 2. The heat source tube 20 is arranged on the side of the support frame 19 away from the heating box 2. Multiple groups of heat conduction ports 21 are arranged on the side of the heat source tube 20 close to the support frame 19; the heating mechanism 22 includes a heating sleeve 23, a heating copper rod 24, a high-frequency coil 25, a metal rod 26, a thermal insulation coating 27 and a temperature sensor 28.

[0021] A controller 29 is disposed on the side wall of the heating box 2 .

[0022] The controller 29 is electrically connected to the proximity switch 12 , the high frequency coil 25 , and the temperature sensor 28 , respectively.

[0023] When in use, open the one-way water injection valve 5, and sterile distilled water enters the interior of the heating box 2 through the one-way water injection valve 5. In the initial state, the copper spring 8 is in an extended setting, and the sterile distilled water falls onto the upper wall of the sliding copper plate 7. The weight of the sliding copper plate 7 increases, and the copper spring 8 uses its own deformation to drive the sliding copper plate 7 to slide down along the inner wall of the heating box 2. After the sterile distilled water enters the middle position of the transparent channel 14, it stops injecting water into the interior of the heating box 2, and the one-way water injection valve 5 is manually closed. At this time, the copper spring 8 changes to a compressed state, and the distance between the sliding copper plate 7 and the heating copper rod 24 is the minimum value; The controller 29 controls the high-frequency coil 25 to start, and the high-frequency coil 25 performs high-frequency induction on the metal rod 26. The temperature of the metal rod 26 rises to heat the inside of the heating sleeve 23. The temperature inside the heating sleeve 23 enters the inside of the heating box 2 under the conduction of the heating copper rod 24. The temperature inside the heating box 2 close to the heating copper rod 24 rises, and the heat inside the heating box 2 is conducted to the inside of the sliding copper plate 7 and the copper spring 8. The sliding copper plate 7 heats the sterile distilled water on its upper wall. The controller 29 controls the temperature sensor 28 to start, and the temperature sensor 28 monitors the heating temperature of the sterile distilled water in real time through the detection end. The thermal insulation coating 27 keeps the heat inside the heating copper rod 24 warm to reduce heat loss. The sterile distilled water in the heating box 2 generates steam after being heated. The steam enters the steam pipe 15 through the transparent channel 14. The connector 16 is connected to the oxygen supply pipe of the ventilator. The steam enters the oxygen supply pipe of the ventilator through the connector 16 and mixes with the oxygen to humidify the oxygen. As the sterile distilled water on the upper wall of the sliding copper plate 7 continues to evaporate, the volume and weight of the sterile distilled water decrease. At this time, the rebound and reset capacity of the copper spring 8 is greater than the weight of the sterile distilled water. The copper spring 8 uses its own deformation reset to drive the sliding copper plate 7 to slide and rise along the inner wall of the heating box 2. The sliding copper plate 7 holds up the sterile distilled water on its upper wall for synchronous movement, thereby avoiding the problem of the sterile distilled water level being lowered and the steam circulation distance being increased due to the evaporation of the sterile distilled water, and reducing the probability of the steam generated by the sterile distilled water being changed into condensed water during the circulation process. As the volume of the sterile distilled water decreases, the distance between the steam source and the oxygen supply pipeline can be always maintained, the temperature of the steam during the transportation process can be maintained, and the humidification efficiency of the sterile distilled water to oxygen can be improved. The controller 29 controls the proximity switch 12 to start. When the sliding copper plate 7 slides and drives the sensing block 11 to a position horizontal with the proximity switch 12, the proximity switch 12 senses the sensing block 11. The proximity switch 12 transmits the sensed signal to the inside of the controller 29, thereby reminding the medical staff to add sterile distilled water into the heating box 2. Repeat the above operation when using it next time.

[0025] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
