Specific embodiment
A kind of Multifunctional sputum aspirator in conjunction with shown in Fig. 1-4, including sputum aspirator tube 1 and casing 2 is protruded into, it is described to protrude into casing 2
Upper end be open end, lower end closed and in semicircle it is spherical.One end of the sputum aspirator tube 1 is connect with negative pressure device, the other end with
It protrudes into casing 2 and matches and be plugged in and protrude into casing 2, hand gear can be used in the negative pressure device, such as negative pressure device is just
It is the air bag with elasticity, holds air bag pressing and loosen, pump out sputum to generate negative pressure.It is described to protrude under casing 2
The side at end is provided with sputum suction hole 3, and the sputum aspirator tube 1 is located at the one end protruded into casing 2 and is provided with the different suction of multiple aperture
Enter hole, the aperture of the inlet hole is less than sputum suction hole 3, and position and sputum suction hole 3 are opposite.
The utility model in use, after the insertion of sputum aspirator tube 1 is protruded into casing 2, will protrude into casing 2 and be inserted into patient
It is intratracheal, using negative pressure device generate negative pressure sputum is extracted out through sputum suction hole 3, inlet hole and sputum aspirator tube 1, needing to adjust
It when suction sputum pressure, protrudes into casing 2 and is kept fixed, slightly rotation sputum aspirator tube 1, the inlet hole of different pore size is made to be directed at sputum suction hole 3 i.e.
It can.By changing the size of inlet hole, the suction sputum pressure at sputum suction hole 3 is adjusted, the demand of different situations is enabled adaptation to, is led to
It is stronger with property.For the ease of sputum towards converging inside sputum aspirator tube 1, first inlet hole 4 and the second inlet hole 5 can also be set
It being set to gradually smaller shape from outside to inside, such sputum can flow into sputum aspirator tube 1 along inclined-plane, it is ensured that suction sputum is smooth,
Its small end is subject in the aperture of inlet hole at this time.
The outer end of the sputum suction hole 3 is as the position directly contacted with tracheal wall, in order to avoid right during suction sputum
Tunica mucosa tracheae generates damage, and better way is, as shown in figure 4, the aperture of 3 outer end of the sputum suction hole is provided with a circle towards evagination
Annular flange 6 out is provided with several notches 7 on the flange 6, and the top sides of the flange 6 are along arc-shaped.Such one
Come, when suction sputum, it will be able to avoid sputum suction hole 3 from being closed completely by tracheal wall, thus greatly reduce tunica mucosa tracheae by
The risk of damage.And the top of flange 6 of arc can also be to avoid scratching tracheae, 6 top of flange namely flange in Fig. 4
6 right edges.
Inlet hole described in the utility model can be set different size of 3 kinds, 4 kinds etc., and for ease of description, this is sentenced
For two kinds: the inlet hole includes the second inlet hole 5 of large-sized first inlet hole 4 and small size, first sucking
The aperture of the aperture >=2mm in hole 4, second inlet hole 5 are less than 1.5mm.When needing to adjust, by the first inlet hole 4 or the
Two 5 turns of inlet hole Winter Solstice and sputum suction hole 3 are opposite.In order to improve the speed of suction sputum, better way is the sputum suction hole 3
It is arranged two groups, and two groups of sputum suction holes 3 are symmetrical in the left and right sides for protruding into casing 2.First inlet hole 4 and the second inlet hole
5 include two groups, and two group of first inlet hole 4 is symmetrical in the left and right sides of sputum aspirator tube 1, and two group of second inlet hole 5 is in sputum aspirator tube 1
Front and back side it is symmetrical.Certainly, when more multiple groups are arranged in sputum suction hole 3, the first inlet hole 4 and the second inlet hole are accordingly increased
5 group number.
It sputum aspirator tube described in the utility model 1 and protrudes into casing 2 and is usually made of silica gel, in order to avoid the utility model suction
Phlegm position compressive deformation, better way are that the fin of several annulars is additionally provided on the outer peripheral surface for protruding into 2 lower end of casing
8, the section semicircular in shape of the fin 8, the fin 8 is interspersed with sputum suction hole 3.The presence of fin 8 further reduced
The impaired risk of tunica mucosa tracheae, while booster action also is played to the lower end for protruding into casing 2.
Since during suction sputum, when slag is more in sputum, inlet hole is easy to be blocked, for this purpose, preferably doing
Method is, as shown in Figure 1, the sputum aspirator tube 1, which is located to protrude by the part outside casing 2, connects short tube 9, the short tube 9 and elastic balloon
10 connections, the elastic balloon 10 is interior to be arranged spring-assisted reduction 11.On sputum aspirator tube 1 between the short tube 9 and negative pressure device
It is additionally provided with manually-operated gate 12.When blocking, manually-operated gate 12 is closed, squeezes elastic balloon 10, inlet hole is carried out anti-
Punching can effectively prevent the generation of blocking, clean without taking out sputum aspirator tube 1.In addition, since the length of sputum aspirator tube 1 is longer,
It has certain reply twisting resistance in the course of rotation, and better way is that the sputum aspirator tube 1 protrudes into casing 2 by being located at
It interior leading portion and constitutes positioned at the back segment protruded into outside casing 2, is connected between the leading portion and back segment by rotary joint 13.
