Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a quantitative synchronous regulator for a humidifier of a ventilator. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine.

[0003] Existing humidification tanks are generally replenished with water in two ways. One is to use a syringe to draw distilled water and inject it into the small water inlet hole until it reaches the marked scale; the other is to unplug the air inlet pipe, pour distilled water from the air inlet hole, and then quickly connect the pipe.

[0004] However, the above method takes too long to add water, which can easily interrupt the air supply of the ventilator. Although the prior art solves the above problem by automatically adding water, the amount of water stored in the humidification tank is large, and if it is not used up in a single use, it is easy to cause a large amount of loss, resulting in high costs. When the water level is low, it is replenished all at once, but when a large amount of replenishment is performed during use, a large amount of cold water entering can easily affect the stability of the respirator, thereby affecting the breathing stability of the user. Utility Model Content

The lowest water level line of the water replenishment tank is higher than the highest water level line of the humidification tank.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 As shown, the utility model provides a quantitative synchronous regulator for a ventilator humidifier, comprising a humidification tank 10, a water replenishment tank 20 is movably arranged at the water inlet end of the humidification tank 10 through a water replenishment channel 40, and a buffer tank 30 is movably arranged at the water outlet end of the humidification tank 10 through a water outlet channel 50, and the water replenishment channel 40 is connected with the water outlet channel 50 to form a synchronous conveying structure;

[0028] Wherein, both the water replenishment channel 40 and the water outlet channel 50 are provided with dual-channel carriers, and liquid pipes for forming different flow rates are movably installed on the dual-channel carriers.

[0029] The utility model adopts a dual-channel connection to form a quantitative synchronous water replenishment structure, controls the synchronous water replenishment at both ends through a controller, sets the corresponding water replenishment amount according to the single required evaporation amount, and forms a secondary water replenishment structure through the dual channels. After the quantitative water replenishment, synchronous dripping is performed through a capillary tube, which is beneficial to reducing the impact of changes in evaporation amount caused by other factors, and is beneficial to improving the stability of the quantitative synchronous water replenishment and reducing losses.

[0030] A dual-channel structure is respectively arranged at the water inlet and outlet of the humidification tank 10. The flow rates of the dual channels at both ends are synchronously driven by a controller, so that water can be replenished synchronously according to the evaporation amount, and a certain amount of supplementation is performed in the form of dripping during use, which is beneficial to reduce the influence of different factors on the evaporation amount and cause the evaporation amount to change, thereby reducing the situation of excessive or insufficient water replenishment, reducing the loss during use and helping to reduce costs.

[0031] like Figure 2As shown, the water replenishment channel 40 includes a water replenishment thick tube 41 and a water replenishment thin tube 42 , and solenoid valves are provided on the water replenishment thick tube 41 and the water replenishment thin tube 42 .

[0032] Water is replenished once through the water replenishment thick pipe 41, and the required water replenishment amount is obtained according to the estimated evaporation amount based on the required time of a single use.

[0033] During use, drip-rate water replenishment is performed through the water replenishment tube 42, which can be used for slow water replenishment to compensate for the error in the estimated amount. In addition, drip-rate water replenishment can reduce the impact on the inside of the respirator during the water replenishment process and maintain the stability of the water replenishment inside the respirator.

[0034] like Figure 1 and Figure 2 As shown, the water outlet channel 50 includes a thick water outlet pipe 51 and a thin water outlet pipe 52, and electromagnetic valves are provided on the thick water outlet pipe 51 and the thin water outlet pipe 52. The water outlet channel 50 outputs synchronously with the water replenishment channel 40 through a controller;

[0035] The water outlet thick pipe 51 and the water replenishment thick pipe 41 synchronously form a large flow channel, and the water outlet thin pipe 52 and the water replenishment thin pipe 42 synchronously form a small flow channel.

[0036] An estimated amount of water is replenished through the thick water outlet pipe 51, and then water is replenished at a dripping rate through the thin water outlet pipe 52.

[0037] The water outlet thick pipe 51 and the water replenishment thick pipe 41 perform synchronous quantitative output through the controller, so that the water replenishment amount at both ends is consistent, which is convenient for pre-caching the water replenishment amount required for a single time, facilitating multiple use to reduce the impact on the unused part.

[0038] During use, water is replenished synchronously through the water outlet tube 52 and the water replenishment tube 42, and a small flow rate is replenished in the form of a drip rate, which reduces the loss of excess water while ensuring sufficient evaporation. It can reduce the instability of the internal temperature and state of the respirator caused by a large flow rate of water replenishment during use, thereby reducing the impact on the user.

[0039] like Figure 2 As shown, a base 11 is movably mounted on the lower surface of the humidification tank 10, a side bracket 12 is fixedly mounted on the base 11, and a support plate 13 is movably mounted on the top of the side bracket 12;

[0040] The support plate 13 is flipped around the connection with the side bracket 12 and movably abuts against the water replenishment tank 20 to form a support structure. The lowest water level line of the water replenishment tank 20 is higher than the highest water level line of the humidification tank 10, and a water replenishment valve is arranged on the upper surface of the water replenishment tank 20.

[0041] During installation, the support plate 13 is rotated to a vertical position with the side bracket 12 to facilitate supporting the water replenishment tank 20 and folding and storage, so that the height of the water replenishment tank 20 is located at a high position of the humidification tank 10. The water replenishment state of the water replenishment tank 20 is controlled by an external sensor, so that the water replenishment is suspended when the water level of the humidification tank 10 reaches the highest water level line, and the water is replenished again when the water level of the humidification tank 10 reaches the lowest water level line.

[0042] like Figure 2 As shown, a respirator connecting pipe 31 is movably installed on the upper surface of the cache tank 30 , and the highest water level line of the cache tank 30 is lower than the lowest water level line of the humidification tank 10 .

[0043] The buffer tank 30 is set at a low position of the humidification tank 10 to facilitate the delivery of the liquid in the humidification tank 10 into the buffer tank 30. The buffer tank 30 is used to cache the amount of water required for single evaporation. The mask end of the respirator is connected to the buffer tank 30 through the respirator connecting tube 31 for use.

[0044] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
