Description

a suction device

technical field

The utility model relates to the technical field of medical instruments, in particular to a phlegm suction device.

Background technique

A sputum suction device is a medical device that inserts a straw into the mouth, nasal cavity, artificial airway, etc., and then uses negative pressure to suck out respiratory secretions to keep the airway unblocked and prevent certain diseases. It is generally used for patients who cannot actively expel sputum, such as comatose patients, patients after anesthesia, and newborns.

The Chinese patent with the publication number CN215821831U discloses a pediatric sputum suction device, which provides a negative pressure inside the sleeve by setting a rubber plug and a pull rod, and the pull rod applies negative pressure inside the sleeve by pulling the rubber plug through a telescopic rod, so that the suction tube can suck out the sputum in the throat of the patient under the action of the rubber plug, reducing the negative pressure of the device, thereby avoiding the damage caused by the existing device to the throat of a child during use.

In the process of implementing the patent, the inventor found that although the negative pressure was reduced by the cooperation of the rubber stopper, the telescopic rod and the pull rod, the reduction of the negative pressure also caused the user to change the position of the straw in the throat several times to absorb the sputum in the throat, and it was easy to leave too much sputum, and the sputum could not be sucked clean.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the technical solution in the utility model is further described.

As shown in Figure 1-2, the embodiment of the utility model proposes a sputum aspirator, including a negative pressure cylinder 1, the two ends of the negative pressure cylinder 1 are connected, and the negative pressure cylinder 1 is provided with an installation block 2 slidingly. The end of the negative pressure cylinder 1 away from the mounting block 2 is provided with a negative pressure assembly for vacuuming the negative pressure cylinder 1, and the bottom of the negative pressure cylinder 1 is threaded with a liquid collection bottle 4 communicating with the interior of the negative pressure cylinder 1, and the liquid collection bottle 4 is located between the negative pressure assembly and the installation block 2. When in use, first drive the installation block 2 to move in the negative pressure cylinder 1 through the driving component, so that the multiple suction tubes 3 extend out of the negative pressure cylinder 1, and then extend the multiple suction tubes 3 to the position where sputum needs to be sucked, and then drive the negative pressure component to vacuum, so that the sputum is sucked into the negative pressure cylinder 1 by the multiple suction tubes 3 and flows into the liquid collection bottle 4. Specifically, the suction tube 3 can use flexible tubes, and the multiple suction tubes 3 are scattered in different positions of the sputum, which increases the scope of suction, thereby reducing the amount of sputum in the area. The suction is cleaner. After the suction is completed, the detachable liquid collection bottle 4 is connected by threads to facilitate removal from the negative pressure cylinder 1 for cleaning. After the device is cleaned, the suction pipe 3 can be retracted into the negative pressure cylinder 1 through the driving component to reduce the pollution of the dust in the air to the suction pipe 3.

As shown in Figure 1-2, further, the driving assembly includes: a driving gear 5, an installation groove 6 is provided on the side wall of the negative pressure cylinder 1, and the driving gear 5 is set in the installation groove 6 through a rotating shaft, and a tooth groove 7 is opened on the top of the installation block 2, and a driving tooth plate 8 is horizontally arranged in the tooth groove 7, and the driving tooth plate 8 is located directly below the installation groove 6, and one side of the driving tooth plate 8 extends into the tooth groove 7 and meshes with the driving gear 5. When the driving mounting block 2 moves in the negative pressure cylinder 1, the driving gear 5 is rotated. Since the driving gear plate 8 on the top of the mounting block 2 meshes with the driving gear 5, by rotating the driving gear 5, the driving gear 5 will drive the driving gear plate 8 to move in the negative pressure cylinder 1, so that the suction tube 3 extends out of the negative pressure cylinder 1 to facilitate the suction of sputum or the suction tube 3 is accommodated in the negative pressure cylinder 1.

As shown in Figure 1-2, further, each end of the suction pipe 3 protruding from the mounting block 2 is provided with an arc-shaped boss 9, and the arc-shaped boss 9 is provided with a through hole communicating with the liquid suction pipe 3 . The arc-shaped boss 9 can protect the throat of the human body. When the liquid suction pipe 3 is inserted into the throat of the human body and moves in the throat of the human body, it is difficult to avoid touching the skin of the human body.

As shown in Figure 2, further, the end of the mounting block 2 away from the suction pipe 3 is provided with a guide platform 10, the bottom of the guide platform 10 is adapted to the inner wall of the negative pressure cylinder 1, and the length of the guide platform 10 is the same as the width of the mouth of the liquid collection bottle 4. The guide table 10 serves to guide the sputum sucked into the negative pressure cylinder 1 by the suction pipe 3 into the liquid collection bottle 4. After the suction pipe 3 has sucked the sputum, the drive assembly drives the installation block 2 to move in the negative pressure cylinder 1 to accommodate the suction pipe 3 in the negative pressure cylinder 1.

As shown in Fig. 1-2, further, the negative pressure assembly includes: a push plate 11, which is slidably arranged at the end of the negative pressure cylinder 1 away from the installation block 2, the push plate 11 is in dynamic and sealed connection with the negative pressure cylinder 1, a push rod 12 is provided on the side of the push plate 11 away from the installation block 2, and a pull rod 13 is provided at the end of the push rod 12 away from the push plate 11. When vacuuming the negative pressure cylinder 1, pull the push rod 12 to make the push plate 11 move toward the end away from the mounting block 2, so that a negative pressure is generated in the negative pressure cylinder 1, which is convenient for the suction pipe 3 to absorb liquid.

As shown in Figure 1-2, further, the outer wall of the negative pressure cylinder 1 is provided with a mounting frame 14, and the inner wall of the mounting frame 14 is provided with a guide groove 15, and the two ends of the pull rod 13 are slidably connected with the guide groove 15. In order to facilitate the user to operate with one hand, by setting the mounting frame 14, the mounting frame 14 can be held by hand during use, and then the pull rod 13 can be pushed with fingers to move along the guide groove 15, so that the liquid suction tube 3 can absorb liquid.

As shown in FIG. 2 , further, a limiting ring 16 is provided inside the negative pressure cylinder 1 , and the limiting ring 16 is located on the side of the mouth of the liquid collection bottle 4 close to the push plate 11 . The limit ring 16 acts as a limit to the push plate 11 , and at the same time, can prevent the sputum on the inner wall of the negative pressure cylinder 1 from contaminating the side wall of the push plate 11 .

As shown in FIG. 2 , further, a sealing rubber pad 17 is provided on the side wall of the push plate 11 . The sealing rubber pad 17 plays a role of sealing, so as to facilitate the formation of a closed chamber in the negative pressure cylinder 1 and facilitate the formation of a vacuum environment.
