Description

An auxiliary device for clearing phlegm

technical field

The invention belongs to the technical field of medical devices, in particular to an auxiliary device for clearing phlegm.

Background technique

In clinical practice, sputum clearing devices are often used for patients who are unable to expectorate sputum or who are confused. breathe. If the adsorption force of the sputum clearing device is too large, it may cause damage to the patient during the process of sputum suction. Therefore, the adsorption force of the general sputum clearing device should not be too large, and because the sputum of some patients is very viscous, ordinary sputum clearing The adsorption force of the device is not enough to suck out the viscous sputum, so it is necessary to inject the phlegm-relieving liquid into the throat of the patient to remove the phlegm, and then suck it out through the sputum-clearing device. In the actual operation process, it is difficult for medical staff to directly judge the viscosity of the patient's sputum. They can only test suction through the sputum clearing device during the operation. , and then use the phlegm-clearing device to clear the phlegm, which is cumbersome and time-consuming.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention provides an auxiliary device for clearing phlegm, which can automatically spray phlegm to dissolve phlegm when the phlegm is too thick, and automatically stop when the phlegm is dissolved and can be sucked out smoothly Spray phlegm, easy to operate.

In order to solve the above-mentioned technical problems, the present invention is solved by the following technical solutions: an auxiliary device for clearing sputum, comprising a pump body, a sputum collection bottle and a sputum suction tube, and the sputum collection bottle is provided with a liquid inlet and a first an air outlet, the phlegm suction tube is connected to the liquid inlet, the first air outlet is connected to the suction end of the pump body, a phlegm-relieving liquid storage bottle is provided on one side of the phlegm collection bottle, and the The phlegm-eliminating liquid storage bottle is provided with a second air outlet, a liquid outlet pipeline and an air inlet, the liquid outlet pipe is connected with a phlegm-eliminating liquid pipe, and the air outlet end of the pump body is connected to the air inlet, and the The first air outlet, the second air outlet and the liquid outlet pipeline are successively penetrated and communicated with a valve casing, a valve core is slidably arranged in the valve casing, and a first channel and a second valve core are arranged on the valve core. Two passages, a return spring is arranged between the end of the valve housing near the first air outlet and the valve core, and an opening is arranged at the end of the valve housing near the liquid outlet pipe, and the sputum The collection bottle is provided with a back pressure valve; in a natural state, the valve core is at the first position, the first passage is connected to the second air outlet, and the liquid outlet pipe is blocked and disconnected by the valve core; When the negative pressure of the phlegm collection bottle increases to a set value, the valve core moves to the second position toward the first air outlet side, the second channel is connected to the liquid outlet pipe, and the second The air outlet is blocked and disconnected by the valve core. When the phlegm-clearing auxiliary device is in use, the phlegm-eliminating liquid storage bottle is filled with phlegm-eliminating liquid, and the phlegm-eliminating liquid does not pass through the suction end of the liquid outlet pipe. The ejection end is aimed at the patient's throat. When the sputum is not very thick, the valve core is always in the first position, and the suction end of the sputum suction tube can normally suck the sputum into the sputum collection bottle. The gas inhaled by the body is discharged from the second air outlet through the phlegm storage bottle; when the sputum is very viscous, the suction end of the sputum suction tube is blocked by the viscous sputum, and the sputum cannot be inhaled normally. Under the action of suction, negative pressure is generated in the sputum collection bottle and the first air outlet, so that the valve core compresses the return spring and moves, and the valve core moves to the second position.
