Abstract
The utility model relates to a disposable thoracic cavity continuous suction unit, which is connected with a three way type suction unit on a nipple of a needle tube of a syringe. Directional control valves are arranged in a liquid sucking valve room and a liquid discharging valve room of the suction unit; the liquid sucking valve room is communicated with a liquid sucking tube having a needle head; the liquid discharging valve room is communicated with a liquid discharging tube. Therefore, the utility model has the advantages of reasonable structure, flexible operation and easy use. The utility model can effectively reduce the labour intensity of working stuff, and effectively avoid the pollution to the inner part of the thoracic cavity of patients and the opportunities of air intake. The utility model is an ideal suction apparatus.
Description
This utility model relate to a kind of in the torso model apparatus of pumping liquid or gas, particularly disposable thoracic cavity continuous suction unit.It is applicable to intrathoracic hydrops of suction or pneumatosis.
The pleurocentesiss that adopt aspirate tapping more when at present, running into hydrothorax clinically.It is to be with rubber tube on the backshank and with the puncture needle of pliers, by the point of puncture of choosing, after the routine disinfection local anaesthesia, to thrust the patient thoracic cavity, and the syringe with 50-100ml is connected to the rubber tube other end then, removes pliers, hydrops in the suction patient thoracic cavity.Adopt above-mentioned apparatus to carry out drawing liquid, often need two people to carry out, wherein a people fixing puncture needle on the other hand, another hand-held pliers, an other people then both hands holds syringe, the attraction liquid of a pipe pipe, and the liquid in the inhalation syringe time arranged in the container that other puts again.Like this, troublesome poeration not only, labor intensity is big, and since syringe nipple be connected the rubber tube need that thrust on the backshank of patient thoracic cavity and contact repeatedly, thereby increased the chance of pollution and air inlet.
The purpose of this utility model is to provide a kind of disposable thoracic cavity continuous suction unit, and it is easy to operate, can be effectively sucking-off hydrops or pneumatosis in the patient thoracic cavity continuously, and reduce pollution and air inlet chance to the thoracic cavity.
Its solution is; On the needle tubing nipple of syringe, be connected with suction pump, it is made of the surge chamber, drawing liquid valve chamber and the discharge opeing valve chamber that are the connection of threeway shape, at drawing liquid valve chamber and the indoor directional control valve that is provided with of tapping valve, and the current limliting direction of two directional control valves is opposite, the drawing liquid flexible pipe that has syringe needle is communicated with the drawing liquid valve chamber, and the discharge opeing flexible pipe is communicated with the discharge opeing valve chamber.
Directional control valve is the tapered cylinders in two ends, is provided with groove vertically at an end of cylinder, so that imbibition or discharge opeing.
This utility model is to be connected with the three way type suction pump on the needle tubing nipple of syringe, and at the taking out of suction pump, the indoor directional control valve that is equipped with of tapping valve, the liquid suction pipe of band syringe needle is communicated with the drawing liquid valve chamber, and discharging tube is communicated with the discharge opeing valve chamber.So it only needs one man operation, can aspirate intrathoracic hydrops or pneumatosis.Like this, not only can reduce operator, reduce staff's labor intensity, and rational in infrastructure, easy to use, and flexible operation can be avoided effectively to intrathoracic pollution of patient and air inlet chance, and is safe in utilization, is a kind of ideal sucting apparatus.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of disposable thoracic cavity continuous suction unit.
Fig. 2 is the A-A cutaway view Amplified image.
Fig. 1, among Fig. 2, on the needle tubing (7) of syringe, have metering scale, pintle (8) is housed in it, on the nipple (6) of needle tubing (7), be set with the suction pump of making by non-toxic plastic, it is a three way type, by surge chamber (5), drawing liquid valve chamber (3) and discharge opeing valve chamber (9) are connected and constitute, directional control valve (4) is housed in drawing liquid valve chamber (3), the drawing liquid latex tubing (2) that has syringe needle (1) is communicated with drawing liquid valve chamber (3), and directional control valve (10) is housed in discharge opeing valve chamber (9), one end of discharge opeing latex tubing (11) is communicated with discharge opeing valve chamber (9), and the other end inserts in the catcher (12).But at directional control valve (4), (10) but an end along taking out to discharge opeing (or gas) is arranged, or the groove (13) of drawing liquid (or gas), the other end is a blind end.Directional control valve (4) with groove (13) end is positioned at the liquid pumping hole place near surge chamber (5), and directional control valve (10) with groove (13) end is positioned at the link place of discharge opeing valve chamber (9) and discharging tube (11).
When pulling syringe pintle (8) intrathoracic hydrops of suction or pneumatosis, according to principle of negative pressure, interior directional control valve (4) with groove (13) end of drawing liquid valve chamber (3) that is communicated with the patient thoracic cavity contacts with surge chamber (5) liquid pumping hole place, in opened condition, hydrops can flow into surge chamber (5) along the groove in the directional control valve (4) in the thoracic cavity, and enter in the needle tubing (7) of syringe, and this moment, the blind end of the directional control valve (10) in the discharge opeing valve chamber (9) is just in time closed the port with surge chamber (5), can avoid the waste liquid in the catcher (12) to flow backwards.When pushing pintle (8), the blind end of the directional control valve (4) in the drawing liquid valve chamber (3) is closed the liquid sucting port that is communicated with the thoracic cavity, can prevent that the liquid in the syringe needle tube (7) from repeating to enter in the thoracic cavity, and the end of directional control valve (10) with groove (13) in discharge opeing valve chamber this moment (9) contacts with the passage port of discharging tube (11), in opened condition, the liquid that has entered syringe needle tube (7) can flow in the catcher (12) through the groove (13) in the directional control valve (10) and discharging tube (11).Carry out so repeatedly, can aspirate intrathoracic hydrops or pneumatosis fully.And can measure what of the hydrops that is drawn out of or pneumatosis by the scale on the syringe needle tube (7).
Claims (2)
1, a kind of disposable thoracic cavity continuous suction unit, it is characterized in that being connected with suction pump on the nipple (6) of needle tubing (7) at syringe, it is the three way type connection by surge chamber (5), drawing liquid valve chamber (3) and discharge opeing valve chamber (9) and constitutes, in drawing liquid valve chamber (3), be provided with in directional control valve (4), the discharge opeing valve chamber (9) and be provided with directional control valve (10), and the current limliting direction of two directional control valves (4), (10) is opposite, the drawing liquid flexible pipe (2) that has syringe needle (1) is communicated with drawing liquid valve chamber (3), and discharge opeing flexible pipe (11) is communicated with discharge opeing valve chamber (9).
2, disposable thoracic cavity as claimed in claim 1 continuous suction unit is characterized in that directional control valve (4), (10) are the tapered cylinder in two ends, is provided with groove (13) vertically at an end of cylinder.
