Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the utility model provides a manual sputum aspirator, which comprises a sputum aspirator 1, wherein an outlet end and an inlet end of the sputum aspirator 1 are respectively connected with a negative pressure cylinder 2 and a sputum aspirator 3, a plurality of connecting ports 4 communicated with the sputum aspirator 1 are sequentially arranged on the sputum aspirator 3 from the inlet end to the outlet end, and a pressure meter 5 and a safety vent 6 are movably arranged on the connecting ports 4.

In the embodiment, the negative pressure cylinder 2 is manually operated to provide a negative pressure environment, and the negative pressure is measured, displayed and ensured by the manometer 5 and the safety vent pipe 6.

Specifically:

the negative pressure cylinder 2 is internally provided with a cavity 7, a piston plate 8 sliding along the inner wall of the cavity 7 is movably arranged in the cavity 7, and the piston plate 8 is connected with a grab handle 10 through a connecting rod 9 penetrating through the end wall of the negative pressure cylinder 2.

In the present utility model, the connecting rod 9 is pulled by the grip 10 and the piston plate 8 is further pulled to move, so that the volume in the cavity 7 becomes large, and in the process, the pressure in the cavity 7 becomes low, thereby forming a negative pressure environment, and the greater the distance the piston plate 8 moves, the greater the negative pressure formed in the cavity 7.

In the present embodiment, since the negative pressure environment is formed first and then sputum aspiration is performed, the sputum aspiration tube 3 is provided with the adjustable switch valve 11, and when the sputum aspiration is not performed, the adjustable switch valve 11 is closed, so that the negative pressure tube 2 and the sputum aspiration tube 1 are integrated, that is, the negative pressure is equal.

The adjustable switch valve 11 can select a flow rate regulator commonly used in infusion, and only needs to have the capability of adjusting the flow rate and switching.

Further, the sputum collection bottle 15 is movably mounted on the connection port 4 closest to the inlet end of the sputum collection tube 2, and according to the foregoing, the pressure in the sputum collection bottle 15 is consistent with the whole system before the sputum collection, so that the sputum can enter the sputum collection bottle 15 to avoid entering the negative pressure tube 2 as much as possible when the sputum collection bottle is used for sucking the sputum, at this time, a guide piece 16 is arranged at the connection port 4 connected with the sputum collection bottle 15, and the guide piece 16 guides the sputum into the sputum collection bottle 15 in an arc shape.

It should be noted that the guiding piece 16 does not completely enclose the sputum aspirator tube 1, but only serves as a stop and guide, so that the sputum is introduced into the sputum trap 15 as much as possible, but not completely, and therefore, the device is also required to be subjected to the corresponding cleaning and sterilizing operations after each use.

When the negative pressure is reduced by the continuous suction, the negative pressure can be supplied by pulling the grip 10 again, and when the grip 10 is pushed back, the adjustable switch valve 11 needs to be closed at this time, and the communication hole 19 provided on the negative pressure cylinder 2 through the movable plug is opened, so that the gas inside is discharged, and when the suction is performed, the communication hole 19 is closed.

When the negative pressure is reached in every drawing, the position of the grab handle 10 is fixed at this time so that the negative pressure is maintained, thereby facilitating the sputum aspiration operation of medical staff, and in this embodiment, the grab handle is fixed in the following manner:

a plurality of locking holes 12 are sequentially formed in the grab handle 10, and a locking rod 14 is connected to the end wall of the negative pressure cylinder 2 through a connecting rope 13, and the locking rod 14 cooperates with the locking holes 12 to position the grab handle 10.

Further, as shown in fig. 1 and fig. 2, the sputum aspirator tube 1 is provided with a safety vent tube 6, the safety vent tube 6 is connected with a closing cap 17, and a pressure membrane 18 is arranged in the middle of the closing cap.

In this embodiment, the pressure membrane 18 can be manufactured according to the maximum safe negative pressure value during sputum aspiration, the safety vent 6 is arranged on the sputum aspirator tube 1, the safety vent 6 is sealed by the sealing cover 17 with the pressure membrane 18 capable of resisting a certain pressure, and the pressure membrane is destroyed when the negative pressure value exceeds a certain safe value, so that the safety vent resumes the ventilation state to interrupt the negative pressure aspiration process.

In this embodiment, by setting the closing cap 17 and the safety vent 6 to be a detachable combination, the closing cap 17 can be replaced after the pressure membrane 18 on the closing cap 17 breaks, so as to be reused, and the closing cap 17 with the pressure membrane 18 capable of bearing different pressure values is also manufactured in advance, the upper limit of the safety pressure value is judged according to the age, physical condition, use condition and other factors of different patients, and the corresponding closing cap 17 is used. By providing the sputum-collecting bottle 15 with the communication port 4 connected thereto in a detachable combination, the sputum-collecting bottle 15 can be replaced after being filled or after a single use is completed.

In this embodiment, since the tissues inside the mouth and the trachea of the patient are fragile and have a certain curvature, the sputum aspiration hose 13 can be better inserted into the tissues and the damage to the tissues inside the patient can be reduced.

The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
