CN203408116U - Backflow preventing saliva suction tube - Google Patents

Abstract

The utility model relates to a backflow preventing saliva suction tube which comprises a drainage tube body, wherein one end of the drainage tube body is sleeved with a drainage head, the other end of the drainage tube body is a drainage tube socket used for being inserted into a saliva suction pipe attached to an oral cavity comprehensive treatment chair, the part of the drainage tube body, which is close to the drainage tube socket, expands outward so as to form a liquid storage cavity inside the drainage tube body, and the liquid storage cavity is used for storing liquid inside the drainage tube body. The backflow preventing suction tube provided by the utility model has the advantages that the structure is simple, the use is convenient, and liquids mixed with blood and saliva of patients are effectively prevented from backflow from the saliva suction tube.

Description

A kind of anti-ptysma-absorbing tube backflowing

Technical field

This utility model relates to a kind of anti-ptysma-absorbing tube backflowing, and for operation on oral cavity or treatment, draws dropsy in mouth cavity, belongs to technical field of medical instruments.

Background technology

In dental care work, patient, in the position that lies low, can accumulate the treatment water of saliva, blood and flushing tooth in oral cavity.When liquid is too much, both can interference treatment process, affect therapeutic effect, also can bring significant discomfort to patient, patient understands that conscious generation is swallowed or the reaction of the discharge opening intracavity hydrops of standing up, and constantly interrupts doctor's operation.

Conventional subsidiary saliva suction pipeline on oral cavity comprehensive treatment chair, can connect disposable ptysma-absorbing tube at present.When compressing switch stops attracting, pipeline transfers closed condition to from vacuum suction state moment, and now in pipeline, also have draining fluids, can produce a small amount of liquid backflows to ground from ptysma-absorbing tube, these liquid that backflow are often mixed with patient's blood, saliva, and the microorganism in oral cavity, pollute environment around, be one of key factor causing stomatologic hospital's infection.Therefore take effective measures, while preventing that negative pressure from closing, the drainage-fluid ptysma-absorbing tube that backflows out is significant.

Summary of the invention

The technical problems to be solved in the utility model is the drainage-fluid ptysma-absorbing tube that backflows out while preventing that negative pressure from closing.

In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of anti-ptysma-absorbing tube backflowing, comprise drain body, drainage head is inserted in one end of drain body, its other end is for for inserting the drainage tube socket of saliva suction pipeline subsidiary on oral cavity comprehensive treatment chair, thereby drain body extends out near the part of drainage tube socket the liquid-storing cavity that portion is within it formed for saving liquid in drain body.

Preferably, at described drainage tube body, be positioned at least one soft metal material silk that be embedded with between described liquid-storing cavity and described drainage head.

Preferably, described metal material silk is copper wire, aluminium wire or galvanized wire.

The utility model has the advantages that: simple in structure, easy to use, can effectively avoid the liquid that is mixed with patient blood, saliva to backflow from ptysma-absorbing tube.

Accompanying drawing explanation

The structural representation of a kind of anti-ptysma-absorbing tube backflowing that Fig. 1 provides for this utility model;

Shape figure when a kind of anti-ptysma-absorbing tube backflowing that Fig. 2 provides for this utility model is used.

The specific embodiment

For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

As shown in Figure 1, the anti-ptysma-absorbing tube backflowing that this utility model provides is comprised of drainage head 1, drain body 2, liquid-storing cavity 3 and drainage tube socket 4.Drainage head 1 is inserted in one end of drain body 2, and the drainage tube socket 4 of its other end inserts subsidiary saliva suction pipeline on oral cavity comprehensive treatment chair.Drainage head 1 at least adopts the soft macromolecular material of food stage, can not damage oral mucosa, and disposable use.Lower end at drain body 2 extends out, thereby portion forms the only liquid-storing cavity 3 of spheroid within it, can save the liquid in drain body 2; In drain body 2, embed a soft metal material silk 5, as copper wire, aluminium wire, galvanized wire etc., when being convenient to doctor and using, curve as required difformity, as shown in Figure 2.

The ptysma-absorbing tube that this utility model provides at least adopts the macromolecular material of food stage, and disposable use.During use, drainage tube socket 4 inserts subsidiary saliva suction pipeline on oral cavity comprehensive treatment chair, and doctor, according to patient's oral condition, curves difformity by drain body 2, and the lowest part that drainage head 1 is placed on dropsy in mouth cavity starts imbibition.While stopping imbibition, the remaining liq in pipette will fall back in liquid-storing cavity 3, can from drainage head 1, not flow out and contaminated environment.

Claims (3)

1. prevent the ptysma-absorbing tube backflowing for one kind, comprise drain body (2), drainage head (1) is inserted in one end of drain body (2), its other end is for for inserting the drainage tube socket (4) of saliva suction pipeline subsidiary on oral cavity comprehensive treatment chair, drain body (2) near drainage tube socket (4) thus part extend out the liquid-storing cavity (3) that portion is within it formed for saving liquid in drain body (2).

2. a kind of anti-ptysma-absorbing tube backflowing as claimed in claim 1, is characterized in that: at described drain body (2), be positioned at least one soft metal material silk (5) that be embedded with between described liquid-storing cavity (3) and described drainage head (1).

3. a kind of anti-ptysma-absorbing tube backflowing as claimed in claim 2, is characterized in that: described metal material silk (5) is copper wire, aluminium wire or galvanized wire.
