Description

The closed thoracic duction instrument of valve

This utility model relates to a kind of chest drainage medical apparatus, and the closed thoracic duction instrument of specifically a kind of valve is applicable to patients such as hydrothorax, hydrops, pneumatosis.

Cut open in breast operation back or the patient thoracic cavity hydrops is arranged, pneumatosis, hydrops, long-pending dense, during hematocele, all need adopt the chest drainage medical apparatus, with intrathoracic hydrops, pneumatosis, hydrops, long-pending dense, hematocele is discharged, this chest drainage medical apparatus commonly used is by drainage bottle (or bag), rubber closure and the drainage tube that inserts in the drainage bottle (or bag), exhaustor constitutes, during use, need in drainage bottle (or bag), to inject a certain amount of water earlier, drainage tube is inserted in the water, go into the thoracic cavity with blocking-up outside air suck-back, make the lung inflation expansion, produce opening pneumothorax, but the severe patient threat to life.The shortcoming of this hydrolock chest drainage medical apparatus is: drainage bottle (or bag) must be fixed on the position that is lower than patient's clinostatism 30-50cm, do not allow drainage tube to extract the water surface, so that tilt or the overturning drainage bottle, liquid must be aseptic in the water seal, use, carry equal inconvenience, thereby increased the painful and inconvenient of patient, and financial burden, also increased nursing staff's labor intensity.

The purpose of this utility model is to provide a kind of and portably uses conveniently, drain is unobstructed, simple in structure, safe and reliable and can alleviate the closed thoracic duction instrument of valve of nursing staff's labor intensity.

This utility model is achieved in that the closed thoracic duction instrument of this valve, constitute by drainage bag, drainage tube, the drainage bag oral area establishes exhaustor and drain is taken over, is communicated with by the membrane flap type check valve between drainage tube and drain are taken over, its membrane flap type check valve has prevented in the drainage tube and the backflow of interior liquid of drainage bag or gas.The closed thoracic duction instrument of this valve is also implemented by following measure: the membrane flap type check valve is made of body and shutoff film lobe, shutoff film lobe is the thin film vertebra tubular of twitching one's mouth, suitable for reading is round mouth, the diameter of round mouth is consistent with the internal diameter of body, be 2cm, its mouthful edge is bonded on the inwall of body, end opening is for twitching one's mouth, the width of twitching one's mouth is the 1/2-2/3 of internal diameter of tube body, strain with the strip elastica at two angles of twitching one's mouth, and strip elastica one end is bonded in the bight of twitching one's mouth, and the other end is bonded on the inwall of body, and in twitching one's mouth in a plane, shutoff film lobe shared length in body is 5-10cm; On the tube body wall above the plugging type film lobe, be provided with medicine-pouring port, when needs when intrapleural injection is treated, can seal valve formula check valve end opening, in the thoracic cavity, inject medicine by medicine-pouring port; On the tube body wall below the shutoff film lobe, establish the negative pressure control valve, after pneumothorax takes place, there are a large amount of gases to overflow into the thoracic cavity as continuing in the lung, when needing vacuum suction, negative pressure can be drawn haustorium and receive on the membrane flap type check valve end opening, intrathoracic pressure is adjusted to-the high water column of 10cm with the negative pressure control valve; The negative pressure control valve is a non-return valve, when drain, and effusive liquid in thoracic cavity or gas, shutoff film lobe round mouth by drainage tube membrane flap type check valve flow to twitches one's mouth, pass twitch one's mouth after, enter drainage bag, if when being negative pressure in the thoracic cavity, under vacuum suction, the closure of twitching one's mouth, if liquid or gas backstreaming are arranged, further the twitch one's mouth film lobe outer wall of both sides of compression then, impel the further sealing of twitching one's mouth, thereby effectively prevented the anti-stream of liquid or gas.

That advantage of the present utility model is is simple in structure, easy to carry, drain is unobstructed, safe and reliable, stable performance, application cost are low.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 3 is this utility model shutoff film lobe elevational schematic view.

Make this utility model with reference to accompanying drawing 1,2,3.The closed thoracic duction instrument of this valve is made of drainage bag 1, drainage tube 2, and drainage bag 1 oral area is established exhaustor 3 and drain and taken over 5, is communicated with by membrane flap type check valve 4 between drainage tube 2 and drain adapter 5.Membrane flap type check valve 4 is made of body 6 and shutoff film lobe 10, shutoff film lobe 10 is the thin film conic tube shape of twitching one's mouth, suitable for reading is round mouth 7, the diameter of round mouth 7 is consistent with the internal diameter of body 6, be 2cm, its mouthful edge is bonded on the inwall of body 6, end opening is for twitching one's mouth 8,8 the width of twitching one's mouth is the 1/2-2/3 of body 6 internal diameters, twitch one's mouth two angles of 8 all with 9 tensions of strip elastica, strip elastica 9 one ends are bonded in 8 bights of twitching one's mouth, and the other end is bonded on the inwall of body 6, and shutoff film lobe 10 shared length in body 6 is 5-10cm; Body 6 walls of shutoff film lobe 10 tops are provided with medicine-pouring port 11, establish negative pressure control valve 12 on body 6 walls of below.
