Description

Anti-backflow sputum suction tube

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to phlegm pipe is inhaled in anti-return.

Background

Sputum aspiration refers to a method for sucking the secretions of the respiratory tract through the oral cavity, the nasal cavity and an artificial airway (tracheotomy) to keep the respiratory tract unobstructed and prevent complications such as aspiration pneumonia, atelectasis, asphyxia and the like. Is suitable for patients with coma and patients with sputum which is particularly likely to suffocate and needs to be administrated in trachea, injected with contrast medium or diluted with sputum. The contraindication is that the patient with skull base fracture forbids nasal catheter to suck the sputum.

The sputum suction device is characterized in that a patient subjected to tracheal intubation or tracheotomy cannot actively spit, sputum is often sucked when the patient spits, a patient with lung infection also needs to suck sputum when the patient spits, a sputum suction pipe is generally used when the sputum is sucked, the sputum suction pipe is provided with a pipe, the outer wall of the pipe is smooth, the upper part of the pipe is provided with a joint and a switch, and the sputum suction pipe is inserted into a trachea and then is used for sucking sputum by negative pressure.

In the technical field of medical instruments, in order to assist patients in sputum excretion, sputum suction tubes are used in large quantities clinically, sputum is sucked out through negative pressure, a traditional negative pressure adjusting mode is that negative pressure adjusting openings are pressed through fingers, the size of the negative pressure adjusting openings is controlled to adjust negative pressure, sputum can be stained with operators when sputum suction operation is directly opened through the negative pressure adjusting openings, sanitation is not facilitated, and the sputum suction tubes are not easy to hold with medical gloves during operation. And the pressure negative pressure adjusting opening is a direct open structure, which is not beneficial to aseptic operation.

Disclosure of Invention

The invention aims to provide a backflow-preventing sputum suction tube which can prevent the backflow of sputum in the sputum suction tube, can collect the sputum in a centralized manner and cannot infect operators.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: an anti-backflow sputum suction tube comprises a catheter connector and a sputum suction guide hose, wherein the catheter connector is communicated with the sputum suction guide hose and is detachably connected with the sputum suction guide hose;

the catheter joint comprises a buffer cavity, a liquid inlet pipe communicated to the inside of the buffer cavity and a negative pressure balloon communicated to the inside of the buffer cavity, a first one-way valve which is communicated with a sputum suction guide hose to the inside of the buffer cavity is arranged in the liquid inlet pipe, an exhaust catheter is arranged on one side, away from the buffer cavity, of the negative pressure balloon, a second one-way valve which is communicated with the outside of the exhaust catheter from the negative pressure balloon is arranged in the exhaust catheter, when the catheter joint is placed horizontally, the outlet position of the liquid inlet pipe is lower than the inlet position of the negative pressure balloon, a funnel-shaped liquid accumulation port is arranged below the buffer cavity, and a liquid accumulation bottle is connected below the liquid accumulation port.

In the above technical scheme, the catheter joint is in threaded connection with the sputum suction guide hose.

In the above technical solution, the buffer cavity is a cylindrical cavity.

In the above technical scheme, the liquid inlet pipe is a line-7-shaped liquid inlet pipe.

In the technical scheme, the negative pressure balloon is an elliptical balloon, and anti-skid stripes are arranged on the outer surface of the negative pressure balloon.

In the technical scheme, the liquid accumulation bottle is in threaded connection with the lower part of the liquid accumulation port.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. the utility model realizes the one-way conduction of the whole sputum suction pipe by arranging the buffer cavity, arranging the first one-way valve at the liquid inlet pipe in front of the buffer cavity and arranging the second one-way valve at the rear of the negative pressure balloon behind the buffer cavity, thereby effectively realizing the sputum backflow and improving the sputum suction effect;

2. the utility model is provided with the funnel-shaped liquid accumulation port below the buffer cavity and is connected with the liquid accumulation bottle below the liquid accumulation port, thereby enabling the sputum to flow into the liquid accumulation bottle after entering the buffer cavity from the liquid inlet pipe, and preventing the sputum from flowing out to infect operators;

3. the utility model discloses an exit position of feed liquor pipe is less than the entry position of negative pressure sacculus, can prevent effectively that the negative pressure sacculus is avoided making dirty in making the sputum splash into because of suction is too big.
