Abstract

The utility model relates to a triggered type synchronous one-way valve, which comprises a basal body (7) and a top cover (1). The triggered type synchronous one-way valve is characterized in that a combined member (2) which is composed of an upper sheet (211), a lower sheet (209), an end plug (208), a press sheet (201), a press cover (206), and a jet nozzle (207), and a diaphragm (11) which divides an inner cavity (10) into an upper cavity (13) are arranged in the inner cavity (10) which is composed of the basal body (7) and the top cover (1). The copmbined member (2) is arranged on the basal body (7) of the inner cavity (10). The diaphragm (11) is arranged on the connecting part of the basal body (7) and the top cover (1). The triggered type synchronous one-way valve causes work to have the characteristic of humanization, and satisfies the requirements that the triggered type synchronous one-way valve has oxygen; when a patient sucks oxygen, when the patient does not suck the oxygen, the triggered type synchronous one-way valve is automatically closed. The triggered type synchronous one-way valve causes that people and a machine are synchronous, the problem that the people and the machine are confronted is solve, and many operation troubles of patients and medical care personnel are alleviated. The triggered type synchronous one-way valve is used for a medical and health care field, or similar occasions.

Description

The synchronous check valve of trigger-type

One, technical field:

This utility model relates to valve, the synchronous check valve of particularly a kind of medical trigger-type.

Two, background technology:

At present, medical gas inlet valve mainly contains two kinds of structures, and a kind of is the wall oxygen inhaler, is made of oxygen absorption mask, effusion meter and water tumbler, is applicable to that continuous oxygen therapic patient uses, and when being interrupted oxygen uptake, needs the people for closing oxygen valve; Another kind is made up of a flow control valve and the container with unidirectional flap valve, its flow control valve equally also needs artificial switch, this just brings great inconvenience to the patient, open during oxygen uptake, close when stopping inhaling, this loaded down with trivial details operation has increased added burden to the patient, and returning the patient sometimes increases unhappyly mentally, influence treatment of diseases and delay rehabilitation.

Three, summary of the invention:

The technical problems to be solved in the utility model provides the synchronous check valve of a kind of trigger-type, it can overcome shortcoming or the deficiency that exists in the above-mentioned prior art well, it can make the patient suct oxygen quickly and easily, reach with inhaling with having, do not inhale the desired level of closing automatically, need not artificially often to open the normal close valve door, alleviated patient burden and nursing staff's troublesome operation greatly.

The technical scheme that this utility model will be dealt with problems is: the synchronous check valve of a kind of trigger-type, comprise matrix and top cover, in the inner chamber that its matrix and top cover constitute, arrangement by last slice, the down molectron formed of sheet, plug, tabletting, gland and nozzle and the barrier film that inner chamber is separated out epicoele, molectron places the substrates of inner chamber, barrier film is placed in the connecting portion of matrix and top cover, and it makes inner chamber be separated into two mutual disconnected spaces.

This utility model matrix is a cylindrical structure, and straight hole and lateral bending hole with intracavity inter-connection are arranged on it.On the vertical end face in this two hole pad is arranged.Molectron last slice, down sheet, plug and nozzle constitute adapter cavity, nozzle is placed in slice.The hole of connection is arranged at the horizontal position top in lateral bending hole on the matrix, and this hole is connected with transition chamber and lateral bending hole, has the balance weight of breach and sealing member on periphery of the upper unit in this hole.Barrier film is the top in this hole of silica gel goods, and wherein subordinate side connects briquetting, and the briquetting other end contacts with gland.

This utility model compared with prior art has its work to have more human features, with inhaling with having, the requirement of closing automatically when not inhaling has been accomplished man-machine synchronous when having satisfied patient's oxygen uptake, solve man-machine antagonism problem, alleviated many troublesome poerations of patient and medical personnel.

Four, description of drawings:

Fig. 1 is this utility model structural representation;

Fig. 2 is this utility model assembling unit structure sketch map.

Five, the specific embodiment:

Referring to Fig. 1, Fig. 2, the synchronous check valve of a kind of trigger-type comprises matrix 7 and top cover 1, and matrix 7 tops connect top cover 1, constitutes inner chamber 10 between matrix 7 and the top cover 1, and in the inner chamber 10, molectron 2 is settled on the top of matrix 7.Following 209 of molectron 2 is installed on the matrix 7,211 constitutes adapter cavities 210 with last slice, and the passway of adapter cavity is sealed mutually by plug 208, has pad 3 and sealing member 6 to seal mutually on the straight hole 9 that adapter cavity and matrix are connected and the vertical end face in lateral bending hole 15.Nozzle 207 devices are on last 211, one end of tabletting 201 is fixed with last slice by screw 202, the other end is flexibly connected by pin 204 and gland 205, make gland 205 be lever construction, one end is pressed on the nozzle 207, the centre is located with spring 212 mutually by dog screw 203, and the other end contacts with barrier film 13 and briquetting 14.Barrier film 13 is installed on top cover 1 and matrix 7 connections, makes inner chamber 10 be separated out not connected epicoele 11, and barrier film 13 is made for silica gel, the middle briquetting 14 that connects.The balance weight 5 that has breach and sealing member on its periphery is installed on the hole 4 that is connected with lateral bending hole 15 and adapter cavity 201 on the matrix 7.Balance weight 5 is a cylinder, and Qi Bishang has vertical breach, and this breach is eccentric orfice, on its circumference sealing ring is arranged, and seals mutually with the inwall in hole 4.The inwall of matrix 7 matches with the outer wall of molectron 2 in the inner chamber 10.Top cover 1 is furnished with the through hole 12 of at least one for end face is convex structure on it, it makes epicoele 11 communicate with atmosphere.During use, lateral bending hole 15 connects oxygen cylinder, and cavity of resorption 16 connects oxygen absorption mask.Before the patient puts on oxygen absorption mask, cavity of resorption 16, upright opening 9, inner chamber 10 and epicoele 11 all communicate with atmosphere, pressure equates with atmospheric pressure, when the patient puts on the oxygen absorption mask oxygen uptake, remove upper cavity pressure and atmosphere and keep balance external, all the other space pressure reduce relatively, and at this moment, the pressure of epicoele 11 is greater than the pressure of inner chamber 10, the briquetting 14 that makes barrier film 13 and connect thereon moves down, compressing gland 205 also moves down thereupon, because the leverage of gland 205, gland 205 is pressed on the end on the nozzle 207 and moves, nozzle is opened, lose heart, the pressure of this time space 17 reduces, pad 3 is drum upwards, and upright opening 9 is connected with lateral bending hole 15, and oxygen is just by in patient's suction body.
