Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, 2, 3 and 4, the droplet extractor of the present invention comprises a handle 1, a droplet collecting cover 3 and an elastic cushion 5.
Wherein, cover 3 and handle 1 integrated into one piece are collected to the droplet, and handle 1 can supply medical personnel to hold and operate, and integrated into one piece has negative pressure line connector 2 on the handle 1, and negative pressure line connector 2 is used for being connected with the negative pressure pipeline, when the in-service use, directly with negative pressure line connector 2 cartridge on the negative pressure pipeline more than the dental treatment. The handle 1 is of a hollow structure, a cavity in the handle forms an airflow channel 7 for airflow to pass through, and the airflow channel 7 is communicated with a corresponding negative pressure pipeline. Be equipped with in the handle 1 and inhale saliva union coupling 6 (refer to fig. 4) that is used for connecting the saliva suction pipe, inhale saliva union coupling 6 and be in handle 1 to inhale the tip that saliva union coupling 6 kept away from negative pressure line connection 2 and the head parallel and level of handle, the medical personnel of being convenient for on the one hand installs the saliva suction pipe, and on the other hand can not influence the suction effect. Inhale saliva union piece 6 and support through setting up three backing sheet 8 on 1 inner wall circumference of handle, during the specific processing, handle 1, inhale saliva union piece 6 and backing sheet 8 integrated into one piece.
The spray collecting cover 3 is a spherical shell and is made of plastics. Elastic cushion layer 5 is the bed course of non-seepage water, adopts the rubber blanket in this embodiment, has certain elasticity, is used for attached face around patient's oral cavity during the use, can take place corresponding elastic deformation according to the facial shape of different patients. The manufacturing materials of the spray collecting cover 3 and the elastic cushion layer are easy to obtain, and the spray collecting cover is simple to manufacture and low in manufacturing cost. The spray collecting cover 3 and the elastic cushion layer 5 are bonded together, and simultaneously, the spray collecting cover 3 and the elastic cushion layer 5 are bonded at one end of the handle 1 far away from the negative pressure pipeline joint, so that a spray collecting cavity 4 for collecting spray generated in the oral cavity of a patient is formed among the spray collecting cover 3, the elastic cushion layer 5 and the negative pressure pipeline joint 2, the spray collecting cavity 4 is communicated with an air flow channel 7 in the handle 1, and the caliber of the spray collecting cavity 4 is larger than that of the air flow channel 7. The spray collecting cover 3 and the elastic cushion layer 5, the spray collecting cover 3 and the negative pressure pipeline joint 2 and the elastic cushion layer 5 and the negative pressure pipeline joint 2 are all connected in a sealing mode. In this way, the droplets collected in the droplet collecting chamber 4 do not leak outside, and the droplet collecting chamber does not leak air during suction, thereby avoiding a reduction in droplet suction effect.
When the spray aspirator of the utility model is used, medical staff firstly directly inserts the negative pressure pipeline joint 2 on the corresponding negative pressure pipeline on the dental therapeutic apparatus, and the terminal of the negative pressure pipeline is connected with a negative pressure generating device and a harmless sewage treatment device; the handle 1 is held by hand, the elastic cushion layer 5 is correspondingly attached to the face around the oral cavity of a patient, the elastic cushion layer 5 deforms according to different face shapes of the patient when contacting with the face of the patient, so that the size of the opening of the spray collecting cavity can be changed, at the moment, the orifice of the spray collecting cavity surrounds a half circle around the oral cavity 9 of the patient (refer to fig. 5 which is the open state of the oral cavity of the patient), and the inner surface of the spray collecting cover 3 not only can block the spray and prevent the spray from splashing around, but also can adsorb the spray; in addition, the inner surface of the elastic cushion layer can absorb the spray. Because the cover is collected to the droplet adopts the spherical shell, can correspond the volume that increases the droplet and collect the chamber to once only collect more droplets. Open negative pressure generating device, produce the negative pressure, do not influence the light source and get into the oral cavity, do not influence under the prerequisite that doctor's sight and operating tool got into the oral cavity, utilize the negative pressure to aspirate the droplet that produces in the patient oral cavity and collect the chamber, reduce the pollution of droplet to consulting room air circumstance, and then reduce the harm healthy to medical personnel and follow-up patient.
In addition, before the spray is sucked, the saliva suction pipe can be screwed on the saliva suction pipe joint 6, and the saliva suction pipe is a flexible pipe and can go deep into the oral cavity of a patient when in use, so that the saliva in the oral cavity of the patient can be sucked while the spray is sucked by using the same negative pressure pipeline.
It should be noted that the utility model discloses a droplet aspirator can not absorb the droplet that produces in the patient's oral cavity completely, nevertheless can intercept most droplet at the oral cavity edge promptly droplet source department to microorganism such as bacterium are to medical personnel's harm in the also greatly reduced droplet. The size of the spray aspirator can be correspondingly designed according to the actual use condition, and the spray aspirator is disposable in actual use due to lower manufacturing cost, so that the spray aspirator is suitable for batch production.
In other embodiments, the droplet collecting cover may also be a planar shell with a cross-section in the shape of a "d", and the elastic cushion may be a rectangular cloth.
In other embodiments, the droplet collecting cap, the handle, the saliva suction tube connector and the support plate may be separately manufactured and then finally glued together by gluing.
In other embodiments, a silicone cloth with good elasticity can be adopted.
In other embodiments, the droplet collecting cover, the elastic cushion layer and the handle may not be hermetically connected, that is, a small gap may be formed at a connection position of the droplet collecting cover and the negative pressure line connector, between the elastic cushion layer and the negative pressure line connector, or at a connection position of the droplet collecting cover and the elastic cushion layer, as long as a suction effect of droplets is not affected.
In other embodiments, no saliva suction pipe connection may be provided, in which case the droplet absorber only acts as a droplet suction, and no saliva suction is performed. Of course, when the saliva suction pipe joint is arranged, the saliva suction pipe joint can also be completely extended into the handle or partially extended out of the handle.
