Abstract
The invention discloses a medical negative pressure suction inverted valve apparatus. The medical negative pressure suction inverted valve apparatus comprises a dirt collecting bottle, a negative pressure suction port, a negative pressure generation port and an inverted valve assembly. The negative pressure space is formed in the dirt collecting bottle, the negative pressure suction port is disposed in the dirt collecting bottle and communicates with the negative pressure space, and the negative pressure suction port is used for sucking dirty water and secretion generated during oral cavity treatment into the dirt collecting bottle through a sucking tube, under the function of differential pressure between pressure in the bottle and the pressure out of the bottle. The inverted valve assembly is arranged in the dirt collecting bottle and connected with the negative pressure suction port. Dirty water in the dirt collecting bottle can be effectively prevented from spilling out, cross infection can be effectively prevented at the same time, so the efficiency of dentistry treatment can be raised.
Description
Technical field
The present invention relates to negative suction system field, especially relate to a kind of Medical negative pressure suction check valve apparatus.
Background technology
In Medical oral cavity therapeutic equipment, suction machine aspirates for the garbage produced in dental care process, sewage etc. being undertaken by the suction force that negative pressure produces the equipment got rid of.This suction machine is usually divided into dry tap formula, half-driedly wet takes out, wetly take out three kinds, dry tap formula negative pressure system is mainly used in being provided with gas-liquid separation device in equipment, or negative pressure equipment can only be installed on the position higher than therapy apparatus plane such as roof, can also Dental Technician Office be arranged in addition, the dust produced when reparation or polishing tooth is aspirated; What wet type negative pressure suction machine adopted is water ring pump, and the feature of water ring pump is that negative pressure value is high and flow is little, be generally used for that operation is more, aspirate based on liquid when, can be used for stomatological hospital and private Outpatient Service Stomatology and operating room etc.
The medical suction machine majority that domestic market occurs is that half-dried wetting is taken out, and its operation principle is drawn in dirt colleceting bucket by the sewage produced during dental care to preserve, and after sewage arrival is a certain amount of, suction machine quits work, and starts sewage effluent.Half-dried wet odd test negative pressure-pumping machine is concentrated and is carried out gas-liquid separation and saved cost; also more convenient installation heavy metal collector; but; in use we find; often there will be the phenomenon generation that sewage overflows in dirt colleceting bucket; be easy to like this cross infection occurs, greatly reduce the efficiency of dental treatment.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
Shown in composition graphs 1 and Fig. 2, a kind of Medical negative pressure suction check valve apparatus that the embodiment of the present invention discloses, for controlling the duty of negative pressure-pumping machine in aspiration procedure, it comprises contamination bottle 1, negative pressure generation interface 2, negative pressure-pumping interface 3 and check valve assembly 4, contamination bottle 1 is for preserving the garbage that produces in dental care process as the sewage in patient's mouth and secretions etc., contamination bottle 1 comprises bottle cap 11 and the bottle 12 of split, bottle cap 11 and bottle 12 are threaded, namely bottle cap 11 inwall arranges female thread, the external screw thread that bottle 12 upper end relative set matches with female thread.The connected mode of bottle cap 11 and bottle 12 is not limited to being threaded here, and it is all applicable that other can realize modes that both connect, and certain contamination bottle also can be the design of integral structure or other structures.
Negative pressure generation interface 2 and negative pressure-pumping interface 3 are all arranged on bottle cap 11, and negative pressure generation interface 2 forms a negative pressure space for making in contamination bottle.Negative pressure-pumping interface 3 connects suction channel (not shown) and is connected with the negative pressure space in contamination bottle, under controlling at bottle inside and outside differential pressure, be drawn in contamination bottle by suction channel by the sewage produced during dental care and secretions, negative pressure-pumping interface 3 can arrange one or more.
Check valve assembly 4 is positioned at contamination bottle 1 and is connected with negative pressure-pumping interface 3, for sealing or unlatching negative pressure-pumping interface 3, controls the duty of negative pressure-pumping interface 3.Particularly, shown in composition graphs 3 and Fig. 4, check valve assembly 4 comprises valve body 41, spool 42, ball float 43 and gag lever post 44, valve body 41 is cylindric, valve body 41 upper end offers the opening 411 be connected with negative pressure-pumping interface 3, and side opening is provided with one or more through hole 412 be connected with contamination bottle 1 inside.Spool 42 is positioned at valve body 41, spool 42 inside for hollow and its top and bottom are opening shape, ball float 43 is positioned at valve body 41, and the diameter of ball float 43 is slightly less than the internal diameter of spool 42, and ball float 43 can arrange one or more.The upper end of spool 42 has a sealing 421, and sealing 421 is fastened in the opening 411 on valve body 41 under the effect of ball float 43 buoyancy, seals up negative pressure-pumping interface 3.In order to strengthen the sealing between the opening 411 on sealing 421 and valve body 41, be arranged with a sealing ring 422 in sealing 421 exterior circumferential, sealing circle 422 can adopt O RunddichtringO.
Gag lever post 44 is fixed in the valve body 41 and position of close valve body 41 bottom, for limiting the position of ball float 43.Gag lever post 44 can be a screw rod.As shown in Figure 3, in its natural state, when namely not having sewage in contamination bottle 1, ball float 43 does not have buoyancy, and now it contacts with gag lever post 44 in self gravitation effect; Along with the sewage in contamination bottle 1 increases gradually, ball float 43, under dirty buoyancy of water, slowly rises to spool 42 top-direction, and band movable valve plug 42 synchronously moves upward; As shown in Figure 4, when spool 42 is pushed up valve body 41 upper end open 411 place by ball float 43 under dirty buoyancy of water, when closedown sealing is carried out to opening 411, now negative pressure-pumping interface 3 is not communicated with the negative pressure space in bottle 12, cannot carry out suction operation, after sewage discharge is gone out, negative pressure-pumping interface 3 is resumed work again, effectively can prevent sewage overflow in contamination bottle 1 out like this, effectively can prevent cross infection simultaneously, improve therapeutic efficiency.
Technology contents of the present invention and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from spirit of the present invention based on teaching of the present invention and announcement; therefore; scope should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present invention and modification should be comprised, and contained by present patent application claim.
