Description

Sputum aspirator

Technical field

The utility model is related to a kind of medicine equipment, more particularly to a kind of sputum aspirator.

Background technology

Such as accompanying drawing 1a-1c is common sputum aspirator, and the first joint 21 connection sputum aspirator tube, the second joint 22 connects negative pressure source Pipeline.Sputum is inhaled into after sputum aspirator tube to be flowed into tank body 10 through the joint 21 on lid 20.But, for more sticky phlegm Liquid, it often gathers the lower end in joint 21 without dripping, at this time, and sputum can be connect by the suction of the second joint to second Head flows and enters the second joint, and then flows in negative pressure source, and one is to block negative pressure source, and two are collected less than sputum sample.

Utility model content

In view of the above problems, the utility model is directed to a kind of suction sputum that sputum can be prevented directly to be inhaled into negative pressure source Device.

A kind of sputum aspirator, it includes tank body and lid, and lid is arranged at the opening of tank body upper end；Lid includes being used to connect Connect the first joint of sputum aspirator tube and for the second joint of the pipeline for connecting negative pressure source；Second joint includes transverse pipe and vertical Pipe；Wherein vertical pipe portion surrounds the middle part of the first joint；Cover plate is provided with the middle part of lid, cover plate is horizontally installed on the whole of lid In inner circumferential, lid is divided into upper space and lower space；The lower end of second joint is located at the upper space；First joint is worn Cross the cover plate and extend downwardly so that the lower end of the first joint is located at the lower space；On cover plate centered on vertical duct Multiple passages are symmetrically offered, upper space is connected with lower space.

Preferably, the vertical duct is located at the geometric center position of the lid.

Preferably, first joint is located at the center of the vertical duct of second joint.

Preferably, the multiple passage is even number.

Preferably, the passage is shaped as circle.

The passage on cover plate, cover plate is set to be connect around described first in the middle part of lid due to sputum aspirator of the present utility model Head is symmetrical, and the plurality of passage is on vertical duct Central Symmetry so that the sputum dripped in the first joint is by every The suction of individual passage is in a balanced way, will not to deviate to any one direction, therefore, sputum will not be drawn onto in negative pressure source.

Embodiment

Below, sputum aspirator of the present utility model is described in detail with reference to accompanying drawing.

Sputum aspirator of the present utility model, it includes tank body 10 and lid 20.

Lid 20 is arranged at the opening of the upper end of tank body 10.

Lid 20 includes being used to connect the first joint 21 of sputum aspirator tube and for the second joint of the pipeline for connecting negative pressure source 22。

Second joint 22 includes transverse pipe and the vertical duct 25 communicated with each other；Wherein vertical pipe portion 25 surrounds the first joint 21 Middle part.

The middle part of lid 20 is provided with cover plate 23, and cover plate 23 is horizontally installed in the whole inner circumferential of lid 20, by 20 points of lid For upper space and lower space.

The lower end of second joint 22 is located at upper space, can be the upper end for being connected to upper space as shown in Figure 2 b, Can extend into upper space.

First joint 21 is extended downwardly through cover plate 23 so that the lower end of the first joint 21 is located at lower space.Specifically Ground, can be connected to the upper end of upper space or extend into as shown in Figure 2 b in upper space.

Multiple passages 24 are symmetrically offered on cover plate 23 centered on vertical duct 25, by upper space and lower space Connection.

Vertical duct 25 can be located at the geometric center position of lid 20, as shown in Figure 2 d, may not be in lid 20 Geometric center.

First joint 21 is located at the center of the vertical duct 25 of the second joint 22.

Multiple passages 24 are preferably even number, such as 4,6,8, so, they each other centered on vertical duct in The heart is symmetrical so that the power that the sputum dripped in the first joint is subject to is cancelled out each other in symmetrical both sides, so sputum only can be down Drop is without being inhaled into negative pressure source.

The shape of passage can be circular or ellipse as shown in Figure 2 c, the other shapes such as rectangle.

In use, sputum aspirator tube is connected with the first joint, the pipeline of negative pressure source is connected with the second joint, negative pressure source starts Afterwards, suction is via the vertical duct of the second joint, upper space, passage and then the lower end for being applied to the first joint, so that by phlegm Liquid is suctioned out from sputum aspirator tube.Due to the distance phase of passage Central Symmetry and each passage and vertical duct around the first joint Deng and Central Symmetry, so the suction at each passage is identical, the sputum that the first joint lower end is dripped is ventilated by both sides The suction equalization in hole, will not deviate to any one passage, thereby guarantee that sputum will not be inhaled into negative pressure source.
