2. using flow velocity adjustment means the speed that adjusting of difficulty negative pressure mechanism extracts main inner air tube can be extracted according to sputum Degree, and then can be drawn into the air inlet of negative pressure mechanism to avoid excessive velocities sputum is extracted, while also helping to sticky Sputum is extracted.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model paediatrics sputum aspirator；

Fig. 2 is that the suction sputum ball of the utility model paediatrics sputum aspirator offers the structural representation of suction sputum stomata side Figure.

Appended drawing reference indicates in figure are as follows: 1- flow velocity adjustment means；Pipeline, 2-1- supervisor, 2-2- branch pipe is connected in 2-；3- inhales Phlegm ball, 3-1- hollow ball, 3-2- suction sputum stomata；4- air guide, 4-1- guiding tube, 4-2- flared tube, 4-3- connecting tube； 5- negative pressure mechanism；6- sputum accommodating container.

Specific embodiment

As depicted in figs. 1 and 2, the utility model paediatrics sputum aspirator, including suction sputum ball 3, air guide 4, sputum are received Receive container 6, conducting pipeline 2, flow velocity adjustment means 1 and for suction sputum operation the negative pressure mechanism 5 of negative pressure, the conducting pipeline 2 are provided Including being responsible for 2-1 and branch pipe 2-2；The air guide 4 includes guiding tube 4-1, flared tube 4-2 and connecting tube 4-3, the flaring Pipe 4-2 is the conduit that mesoporous is bellmouth；The inlet end fluid communication of the outlet side of the suction sputum ball 3 and the supervisor 2-1 connect It connects, the outlet side of the supervisor 2-1 is got through with the inlet end fluid of the flow velocity adjustment means 1 to be connect, and the flow velocity adjusts structure The outlet side of part 1 is connect with the inlet end fluid communication of the negative pressure mechanism 5, and 5 outlet side of negative pressure mechanism is communicated with the atmosphere； Supervisor's 2-1 mesoporous is connect with the outlet side fluid communication of the branch pipe 2-2, and the inlet end of the branch pipe 2-2 and setting exist Gas vent fluid communication connection on the flared tube 4-2 tube wall；The outlet side of the sputum accommodating container 6 and the connecting tube The inlet end fluid communication of 4-3 connects, and the outlet side of the connecting tube 4-3 connect conducting with the inlet end of the flared tube 4-2, The outlet side of the flared tube 4-2 is connect with the inlet end fluid communication of the guiding tube 4-1, the air inlet of the guiding tube 4-1 It holds and is connect with the mesoporous fluid communication of the supervisor 2-1；The upper end of the guiding tube 4-1 and the fixed company of supervisor's 2-1 tube wall It connects, the lower end of the guiding tube 4-1 is fixedly connected with the necking end of the flared tube 4-2, the flared end of the flared tube 4-2 It is fixedly connected with the upper end of the connecting tube 4-3, the lower end of the connecting tube 4-3 detachably connects with the sputum accommodating container 6 It connects；The negative pressure mechanism 5 is medical negative pressure suction system, and the flow velocity adjustment means 1 are throttle valve.Wherein, the suction sputum ball 3 Including hollow ball 3-1, the hollow ball 3-1 hemisphere far from supervisor's 2-1 inlet end is equipped with 9 suction sputum gas Hole 3-2, the suction sputum with stomata 3-2 be hole without leave outside the hollow ball 3-1 on the inside of the lateral hollow ball 3-1 gradually The conical through-hole of diminution, the cone angle of the suction sputum stomata 3-2 are 5 °, and the conical through-hole is conducive in same condition of negative pressure It can make down to form a pressure difference inside and outside the conical through-hole outlet side, be more advantageous to sputum and be inhaled into the hollow sphere In body 3-1, and when encountering more sticky sputum, the conical through-hole is also beneficial to sticky sputum deformation, thus favorably It is drawn into the sputum accommodating container 6 before restoring original shape in sticky sputum.

For the ease of the replacement of the sputum accommodating container 6, in the present embodiment, received using back cover cylinder as the sputum Container 6 of receiving uses, and 6 upper end of sputum accommodating container is connect with the connecting tube 4-3 lower thread.

When sticky sputum is more, sticky sputum meeting congestion relies solely on itself of sputum in the supervisor 2-1 The negative pressure that gravity and the guiding tube 4-1 are formed after the branch pipe 2-2 is connected to the supervisor 2-1 is difficult to draw sticky sputum It flow in the sputum accommodating container 6, therefore, is drawn into the sputum accommodating container 6 for the ease of sticky sputum, this implementation In example, when sputum enters in the supervisor 2-1 and flow at the supervisor 2-1 above the guiding tube 4-1, it is located at institute It states the supervisor 2-1 between branch pipe 2-2 upper end tube nozzle and the guiding tube 4-1 upper end tube nozzle and is equipped with fluid stopping component, it is described Fluid stopping component is haemostatic clamp.

When using the utility model, the suction sputum ball 3 is placed into through Pediatric Oral Emergency pharyngeal, then adjusts the flow velocity tune Section component 1 gradually decreases pressure in the conducting pipeline 2, until sputum is extracted from children are pharyngeal, when appearance more When sticky sputum, can will be located at haemostatic clamp the branch pipe 2-2 upper end tube nozzle and the guiding tube 4-1 upper end tube nozzle it Between the supervisor 2-1 clamp so that the negative pressure mechanism 5 can only be by being located at the flow velocity adjustment means 1 and the branch pipe The supervisor 2-1, the branch pipe 2-2, the guiding tube 4-2 between 2-2 and it is located at the guiding tube 4-2 and the suction sputum The supervisor 2-1 between ball 3 carries out suction sputum, thereby may be ensured that more sticky sputum is inhaled into the sputum storage and holds In device 6, without being drawn at the air inlet of the negative pressure mechanism 5, consequently facilitating continuous in the case where patient's sputum is more Ground carries out suction sputum using the same sputum aspirator.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among still in present patent application scope of protection of the claims.
