Description

Automatic liquid supplementing and humidifying tank capable of guaranteeing water level for breathing machine

Technical Field

The invention relates to the technical field of medical equipment, in particular to automatic liquid supplementing of a breathing machine capable of ensuring water level

A humidifying tank.

Background

Some critical patients need to establish an artificial airway and use a respirator to assist breathing, but after the artificial airway is established, the humidifying function of the respiratory tract of the human body is lost, and if oxygen which is not humidified is directly inhaled for a long time, bronchial secretions are sticky and are not easy to suck or cough out, and sputum scab is formed, so that a series of complications are generated. It is therefore necessary to improve the humidification function of the existing ventilator.

At present, the clinical common method for adding water to the humidifying tank of the respirator in the background technical description of the prior patent literature cited in the application has three methods: firstly, the separation respirator and an air inlet pipeline are poured from an air inlet; secondly, the distilled water is extracted by a syringe and injected from a liquid inlet; thirdly, the disposable infusion apparatus is used to insert the nipple into the small liquid inlet hole for timing liquid feeding.

The first method and the second method cited in the description of the prior patent documents in the application have the problems that the pipeline of the breathing machine needs to be disconnected when water is added, so that the pressure in the pipeline is suddenly reduced, low-pressure damage is caused, and the infection of the pipeline of the breathing machine is increased by repeatedly disconnecting a loop; the third method is ideal, but the method can not maintain the water level at the water level line all the time, and can cause respiratory complications such as choking cough and even asphyxia for patients due to excessive liquid adding quantity, or cause burning of a breathing machine due to insufficient liquid adding quantity to influence the patients.

At present, although the flow rate control device, the ball valve device, the float valve device and the limiting suspension device are used for solving the problems, the design is complex, the nipple of the disposable infusion apparatus is inserted into the liquid inlet small hole by using a liquid supplementing mode, and the mode has the problems of infirm fixation, easy separation after touch and the like.

Disclosure of Invention

The invention overcomes the defects of the prior art and the existing practical problems in clinic, and solves the problems of respiratory tract complications, burning of the breathing machine and the like caused by overhigh or overlow water level when a critically ill patient uses the breathing machine; and the defects of complex design, infirm fixation, incapability of maintaining the water level at the water level line all the time and the like in the prior art are overcome.

The technical scheme adopted by the invention for solving the technical problems is as follows: an automatic liquid supplementing and humidifying tank of a respirator, which can ensure the water level, comprises a humidifying tank body of the respirator and 1 specially-made infusion set, the humidifying tank body of the breathing machine is provided with an air inlet, an air outlet and a liquid inlet, the inner diameter of the liquid inlet is 12mm, which is the minimum inner diameter capable of realizing the air pressure balance principle, and a liquid inlet pipe with the same inner diameter as the liquid inlet pipe extends from the liquid inlet to the interior of the humidifying tank body, which extends to the water level of the humidifying tank body and is provided with a first sealing ring to ensure the tightness, thereby based on the air pressure balance principle, so as to realize the replacement of the air below the water level line of the humidifying tank body and the liquid in the special infusion apparatus, namely, the heating action of the respirator can evaporate the liquid in the humidifying tank body to generate air between the end plane of the liquid inlet pipe and the water level line plane, the air can enter the special infusion apparatus through the liquid inlet pipe, so that the liquid in the special infusion apparatus is replaced.

The special infusion apparatus comprises an insertion connector, an infusion tube and a reinforcing iron ring, wherein the inner diameter of the insertion connector is 12mm, the inner diameter of the insertion connector is the minimum inner diameter capable of realizing the air pressure balance principle, the special infusion apparatus is provided with a valve, a second sealing ring and a reinforcing device, the insertion connector is connected with the liquid bottle and is fixed by the reinforcing device, the second sealing ring is used for ensuring the airtightness, the valve is used for controlling whether liquid in the liquid bottle is led in or not and enabling the special infusion apparatus to be in the airtight state when the liquid bottle is replaced, the tail end of the infusion tube is connected with the liquid inlet, and the special infusion apparatus is firmly and airtightly connected by the reinforcing iron ring.

The invention has the advantages that the automatic infusion device can not only automatically replenish liquid, but also maintain the water level at the water level line at any time, thereby being beneficial to the treatment of patients; the special person is not needed to take care of, so that the workload of nursing staff can be reduced; simple design, convenient operation, rapid fluid infusion time and the like.
