Abstract

The utility model discloses a tracheal intubation joint, which belongs to an auxiliary implement for chest surgery heart massage. The utility model is composed of a tracheal joint, a left pressure plate, a movable flap supporting plate, a right pressure plate and an external joint which are fixedly connected by screw rods; a big and a small through holes are respectively arranged on the left and the right pressure plates; a rectangular through hole is arranged on the movable supporting plate between the left and the right pressure plates; the inner part of the through hole is provided with a long and a short movable flaps which are connected by a supporting shaft; parts of the opposite ends of the two movable flaps are staggered; springs on the outer edges of the flange plates of the two joints penetrates through the through holes on the pressure plates, and relatively act on the short movable flap. The tracheal intubation joint can be widely used for the emergency treatment of patients whose heart stops beating, raising the success ratio of the emergency treatment.

Description

The tracheal intubation joint

This utility model relates to a kind of emergency medical apparatus, especially a kind of gas spigot joint of auxiliary closed cardiac massage.

At present, the clinical rescue heart stops the method that dancing patient adopts closed cardiac massage, by increasing intrathoracic pressure power to pushing outside the thoracic cavity, thereby influence and penetrate blood, thereby decontrol back thorax reset generation negative pressure and influence blood backflow in the heart, but communicate with the external world all the time for respiratory tract, so pushing the pressure of thorax generation is offset little to the influence of heart thus basically by the aerofluxus of pulmonary, the cardiac ejection wretched insufficiency, can not satisfy the demand of bodily tissue organ, thereby cause salvage success rate lower blood and oxygen.

The purpose of this utility model provides a kind of tracheal intubation joint of pleural pressure when increasing closed cardiac massage.

Tracheal intubation joint of the present utility model, it comprises the following parts that are arranged in order: the hollow external lug of the hollow gas-tpe fitting of flanged dish, left platen, flap valve supporting disk, right platen and flanged dish, on the relevant position of the outer rim of above each parts, have connecting hole, and pass connecting hole successively by screw rod each parts is fixed together; Ring flange outer rim in gas-tpe fitting and external lug respectively has a threaded spring embedded hole, and hollow spring adjusting screw(rod) places the spring embedded hole, and the spring adjusting screw(rod) is embedded with an outstanding spring, the position correspondence of two springs; On the junction block of gas-tpe fitting, also be connected with a pressure gauge connection, what link to each other with its ring flange in gas-tpe fitting and external lug inboard is respectively identical left platen of structure and right platen, left side platen and right platen have two square openings up and down on its vertical direction axis, the top square opening communicates with the cavity of gas-tpe fitting, external lug, two square openings with the horizontal hole wall of the opposing side of ring flange on design chamfering structure is arranged; It between the platen of the left and right sides flap valve supporting disk, the flap valve supporting disk has a rectangular through-hole on its vertical axis, the rectangular through-hole position is corresponding with the square opening on the platen, on in the rectangular through-hole, under be respectively equipped with length, short two flap valves, two flap valves flexibly connect by back shaft and flap valve supporting disk, the width of bivalve width and rectangular through-hole is suitable, two flap valves can freely swing in the certain limit in the square opening on rectangular through-hole and the platen, long, short flap valve has held fraction staggered in opposite directions, and short flap valve is passed the gas-tpe fitting of less square opening on the platen and the relative vertical position that is pressed on of spring in the external lug.

Because the flap valve swung that this utility model adopted especially is subjected to the structure of the pressure effect of back-moving spring during the short flap valve swing of the long and short flap valve part alternation sum on the flap valve supporting disk, open gas passage when making each the breathing and all need overcome certain resistance, promptly when exhaling, increase intrathoracic pressure, increase intrathoracic negative pressure when air-breathing, make the outer massage of breast be able to, improve the success rate that gives emergency treatment to a patient to the bigger effect of heart.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the cutaway view of this utility model tracheal intubation joint.

Fig. 2 is the front view of left platen among Fig. 1.

Fig. 3 is the front view of flap valve supporting disk among Fig. 1.

In Fig. 1, the tracheal intubation joint comprises the hollow external lug 5 of hollow gas-tpe fitting 1, left platen 2, flap valve supporting disk 3, right platen 4 and the flanged dish of the circular flanged dish that is arranged in order, more than the outer rim relevant position of each parts have connecting hole and pass successively and fixedly connected by screw rod.Respectively have a spring embedded hole on the outer rim relevant position of the ring flange of gas-tpe fitting 1, external lug 5, be equipped with a spring adjusting screw(rod) 7,8 in the embedded hole, spring adjusting screw(rod) 7,8 is embedded respectively an outstanding spring, in addition, also be connected with pressure gauge connection 6 on the gas-tpe fitting pipe, intrathoracic pressure be can in rescue, observe thus, the excessive patient's of causing pneumothorax of pressure or the too for a short time ideal effect that do not reach of pressure prevented.Externally also be connected with an external apparatus interface 11 on the joint 5, it can link to each other with respirator or air bag, the left side that structure is identical, right platen 2,4 have two square openings on the axis of its vertical direction, two square opening width are identical, the top square opening is than bottom square opening big (as shown in Figure 2), top communicates than the cavity of large square hole with gas-tpe fitting 1 and external lug 5, on, down two square openings with the horizontal hole wall of the opposing side of ring flange on design chamfering structure is arranged, flap valve supporting disk 3 is positioned at a left side, right platen 2, between 4, on its vertical axis, have a rectangular through-hole on the flap valve supporting disk, the rectangular through-hole position is corresponding with the square opening on the platen, on in the rectangular through-hole, under be respectively equipped with length, short two flap valves 9,10 (as shown in Figure 3), two flap valves flexibly connect by back shaft and flap valve supporting disk, the width of bivalve width and rectangular through-hole is suitable, but two flap valves can freely swing in the certain limit in the square opening on rectangular through-hole and the platen, and hunting range is limited by the chamfering of platen square opening; Long and short flap valve 9,10 is held in opposite directions all to be wedge shape and to have fraction staggered so that rectangular through-hole is blocked, and this structure can guarantee to have between flap valve and the flap valve supporting disk certain air-tightness and flap valve relative movable with relatively more flexible.Gas-tpe fitting and the spring in the external lug that short flap valve 10 is passed less square opening on the platen are fixed on the vertical position, and we can adjust the suitable break-make resistance of gas passage by the relative position of regulating spring adjusting screw(rod) 7,8 like this.

The gas-tpe fitting of this tracheal intubation joint is connected with tracheal intubation in inserting patient's trachea during use, directly emptying of external lug, and pressure tapping connects Pressure gauge.Original state two flap valves are closure state, when massaging outside imposing breast, could against the force of the spring be opened by flap valve when thoracic cavity gas need reach certain pressure, strengthen intrathoracic pressure power thereby reach, and strengthen the effect of cardiac ejection.
