Description

Oxygen inhalation equipment for patient

Technical Field

The invention belongs to the field of medical care equipment, and particularly relates to oxygen inhalation equipment convenient for a patient to inhale oxygen comfortably.

Background

In hospital clinics, many patients often require oxygen therapy. While continuously dry oxygen passing through the patient's respiratory tract can cause damage to the respiratory tract. To avoid such damage, the dry oxygen needs to be humidified. In order to achieve the purpose of oxygen humidification, an oxygen humidification bottle is added between an oxygen supply center and a nasal oxygen tube (or an oxygen mask) so that continuously dry oxygen can be humidified after passing through humidification liquid in the humidification bottle and then enters a patient body through the nasal oxygen tube (or the oxygen mask). Thus, damage to the patient's respiratory tract by the continuously dry oxygen is avoided. However, the existing oxygen humidification bottle generally contains water in a bottle body, and then the bottle cap is connected with an aeration pipe which is introduced into water, so that moisture is carried in the process of oxygen contacting with water, thereby achieving the purpose of humidifying oxygen, but the oxygen comes out from the aeration pipe and upwards comes out from the water, so that larger noise (45-65 decibels) can be generated, when the oxygen flow is larger, the noise is more prominent, and the rest of patients with poor sleep quality and fear of noise is influenced.

In addition, the oxygen inhalation through the nasal oxygen tube has the advantages of simplicity, low price, convenience, comfort, no influence on food intake and water drinking, and the defect of inapplicability to patients with nasal obstruction and mouth-opening breathing; the oxygen inhalation mask has the advantages of ensuring the concentration of inhaled oxygen, being suitable for patients who breathe by mouth opening, and having the defects of restraint and occlusion feeling of the patients and inconvenient eating and drinking.

The water sprayed by the atomizing nozzles is gradually accumulated in the upper bottle body, the annular air inlet pipe is of a hollow structure, the average density of the annular air inlet pipe is lower than that of the water, the annular air inlet pipe can float on the water surface, and the sprayed oxygen cannot submerge below the water surface to generate aeration sound, so that only slight sound generated when the atomizing nozzles spray the water mist in the humidifying bottle is provided, and no sound generated when gas emerges from the water, through practical tests, when the oxygen flow is 5L/min, the noise of the invention is about 25 decibels, and when the oxygen flow is 10L/min, the noise of the invention is about 30 decibels, and the noise reduction effect is obvious compared with the noise reduction effect in the prior art.

When the piston moves to the upper end of the lower bottle body, the piston can drive the driving rod 41 to move upwards, so that the driving rod permanent magnet 412 is attached to the lower end face of the partition plate, the steel sheet 74 at the lower end of the valve rod 71 is attracted to the driving rod permanent magnet, the valve rod moves downwards, the vent hole b is opposite to the vent hole a, the vent hole c is staggered with the vent hole a, the effective area of gas entering the gas inlet valve pipe is reduced because the area of the vent hole c is 10-20 times of the area of the vent hole b, the air pressure in the upper bottle body is slowly increased, when a certain value is reached, water in the upper bottle body can break through the one-way valve sheet and enter the lower bottle body through the return port 323 and the water inlet 324, the piston in the lower bottle body can move downwards, when the limiting connector on the piston touches the limiting head, the piston can drive the driving rod to move downwards, the valve rod moves upwards, and the vent hole b and the vent hole c are opposite to the vent hole a, so that the valve disclosed by the invention works normally.

When the piston moves downwards from the upper part of the lower bottle body, the permanent magnet of the driving rod cannot be separated from the steel sheet to attract in the initial stage, water in the upper bottle body enters the lower bottle body, if all water in the upper bottle body enters the lower bottle body, but the piston does not touch the limiting head, at the moment, because the air pressure of the upper bottle body is continuously increased, air in the upper bottle body enters the lower bottle body through the one-way valve plate, the piston continuously moves downwards until the piston moves to touch the limiting head, the permanent magnet is separated from the steel sheet, the air in the lower bottle body can quickly flow out through the water inlet pipe and the atomizing nozzle, and the liquid level of the lower bottle body quickly rises, so that the water-.

The process that the piston moves downwards is finished within 10-20s, the atomizing nozzle stops working in the process, the air outlet speed of the air outlet joint is reduced in the process, the humidity of the exhausted oxygen is reduced, and the time is short, so that the patient can not feel obvious and normal oxygen inhalation is not influenced.

Example 3

The present embodiment makes the following improvements on the basis of embodiment 2: a water injection funnel is arranged in the water injection seat; a limiting block 51 is formed at the upper part of the outer wall of the water injection funnel; the water injection seat is provided with a limiting groove a221 and a limiting groove b222 which are connected with the limiting block in a sliding manner; the limiting groove a is shorter than the limiting groove b; the lower end of the water injection funnel is uniformly formed with valve piece opening rods 52 along the circumference; an exhaust groove 53 for releasing gas in the lower bottle body is formed on the outer side of the water injection funnel; when the limiting block is matched with the limiting groove b, the valve plate opening rod opens the one-way valve plate; when the limiting block is matched with the limiting groove a, the valve plate opening rod is not contacted with the one-way valve plate, and the lower end of the water injection funnel is higher than the upper end of the backflow port.

The circumference of the outer wall of the piston adjusting ring is provided with a rotary raised head 31 which is convenient for rotating the piston adjusting ring.

A base clamping groove 34 is formed at the lower part of the inner wall of the lower bottle body; the base outer wall shaping has the base dop 81 with base draw-in groove joint.

The valve block of intaking is including circular shape valve block portion and the connecting rod portion of integrated connection in the middle of the valve block portion, the oral area of intaking is including the connecting hole and the import of even shaping in the connecting hole periphery of being connected with connecting rod portion interference.

A partition plate 31 is formed at the upper part of the lower bottle body, and an internal thread connecting part which is connected with the upper bottle body through threads is arranged on the inner wall of the inner bottle body above the partition plate; and a sealing ring 36 which is positioned on the inner periphery of the internal thread connecting part at the upper end of the partition board and is in sealing and abutting contact with the lower end of the upper bottle body is arranged on the inner periphery of the internal thread connecting part at the upper end of the partition board.
