Abstract

The utility model relates to a piston type thoracic cavity closed type drainage bag, which is composed of a unidirectional and automatic piston, a piston tube, a drainage bag, a drainage tube, a drainage tube joint, a thoracic cavity puncture needle, a suspension hook, a discharge tube and a discharge tube cap. When the utility model is used, positive pressure and negative pressure in a thoracic cavity produced by patients' air suction and exhalation cause the unidirectional and automatic piston to move up and down in the piston tube, and thereby, liquid and air in the closed type thoracic cavity can be drained out automatically, and can be directly drained into the drainage bag. The utility model has the characteristics of small size, simple structure, easy and convenient operation, convenient carrying, no other power units, etc. The utility model is suitable for drainage and emergency treatment of closed type liquid and air thorax under ordinary and wartime conditions.

Description

The piston type closed thoracic drainage bag

This utility model relates to a kind of medical apparatus and instruments that is used for the closure hydropneumothorax.

A kind of thoracic drainage and thoracentesis device is arranged at present, mainly connects to form one successively by puncture needle, drainage tube, unidirectional drain pump and drainage bag, though this drainage device need not manually aspirate, time saving and energy saving, need other power set.

The purpose of this utility model provides the piston type closed thoracic drainage bag that a kind of volume is little, simple in structure, easy to operate, easy to carry, do not need other power set, make that it is suitable for putting down, under the war condition to the drain and the first aid of closure hydropneumothorax.

The purpose of this utility model be achieved in that this utility model mainly by unidirectional automatic piston, piston tube, drainage tube, drainage tube joint, thoracentesis needle, drainage bag, hang, comb, comb medicated cap constitute.Piston tube is connected into " U " type structure by an end of piston tube input and drainage tube, and be vertically fixed on the drainage bag internal upper part, the piston tube outfan is by a short and small drainage tube and drainage bag inner chamber UNICOM, drainage tube is drawn by the drainage tube place of drawing, its other end connects with the drainage tube joint, the drainage tube joint of drainage bag connects with thoracentesis needle and the direct closed pneumothorax of inserting during use, or the drainage tube joint directly connects with another drainage tube that inserts the thoracic cavity, piston type closed thoracic drainage bag after the connection is air-tight state, the thoracic cavity is in barotropic state when air-breathing, can discharge the liquid gas in the closed pneumothorax automatically, and directly enter drainage bag, the thoracic cavity is in negative pressure state when exhaling, closure piston pipe automatically, and liquid gas can not backflow.In order to prevent that thoracic cavity liquid gas under small negative pressure from backflowing, end with piston tube input and drainage tube is connected into " U " type structure especially, and make it be vertically fixed on the drainage bag internal upper part, and make the piston tube input downward all the time, unidirectional automatic piston is in all the time treats closed condition.

This utility model directly utilizes positive negative pressure in the patient thoracic cavity air-breathing, that produced when exhaling, the interior unidirectional automatic piston of piston tube is moved up and down, automatically discharge the liquid gas in the closed pneumothorax, it is simple in structure, do not need other power set, and it is little, easy to operate to have a volume, characteristics such as easy to carry, be suitable for putting down, under the war condition to the drain and the first aid of closure hydropneumothorax.

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is the structure chart of this utility model piston type closed thoracic drainage bag.

Among Fig. 11, drainage bag 2, the drainage tube place of drawing 3, comb 4, comb medicated cap 5, hang 6, drainage tube 7, piston tube outfan 8, piston tube eck 9, piston tube 10, piston tube eck 11, piston tube input 12, unidirectional automatic piston 13, drainage tube joint 14, thoracentesis needle 15, drainage tube

Drainage bag 1 upper end hangs 5 in Fig. 1, and have drainage tube draw the place 2, there is comb 3 lower end, comb 3 and comb medicated cap 4 socket-connect, unidirectional automatic piston 12 is in piston tube 9, piston tube 9 is connected into " U " type structure by an end of piston tube input 11 and drainage tube 6, and be vertically fixed on drainage bag 1 internal upper part, it is downward to connect back piston pipe input 11, piston tube outfan 7 makes progress, and piston tube outfan 7 is by drainage tube 15 and drainage bag 1 inner chamber UNICOM, and drainage tube 6 is drawn by the drainage tube place of drawing 2, its other end connects with drainage tube joint 13, and drainage tube joint 13 can connect with thoracentesis needle 14.Piston tube 8 length are 42 millimeters, and its maximum gauge is 10 millimeters, 4 millimeters of two-port diameters, 2.4 millimeters of internal diameters, 0.8 millimeter of thickness.Piston tube eck 10 is rounded, piston tube eck 7 is square or irregular shape, unidirectional automatic piston 12 is installed in piston tube 9, unidirectional automatic piston 12 lower ends are rounded, unidirectional automatic piston 12 upper ends are square or irregular shape, unidirectional automatic piston 12 can move up and down with the change in location of liquid gas, unidirectional automatic piston 12 is as when piston tube input 11 moves, unidirectional automatic piston 12 is tightly airtight with piston tube 9 walls, and unidirectional automatic piston 12 can not be airtight with piston tube 9 walls as unidirectional automatic piston 7 when piston tube outfan 7 moves.Drainage tube 6 and drainage tube 15 bores are slightly larger than piston tube outfan 7 and piston tube input 11 bores, reach to put piston tube outfan 7 and piston tube input 11 and want closely, till the difficult drop-off.Drainage tube joint 13, its pipe diameter is 4 millimeters, links with drainage tube 6 and wants closely.Unidirectional automatic piston 12 and drainage tube coupling head 13 are made by glass, drainage bag 1, drainage tube 6, drainage tube 15, hang 5, comb 3, comb medicated cap 4, can make with silica gel, plastic cement or plastics, thoracentesis syringe needle 14 is common puncture needle.Each parts of this utility model connect wants close and firm, can not leak gas, leakage, drainage bag 1, drainage tube 6 and drainage tube 15 can not be damaged, liquid gas can only enter in the drainage bag 1 by thoracentesis needle 14 or drainage tube joint 13, drainage tube 6, piston tube input 11, piston tube 9, piston tube outfan 7 and drainage tube 15, makes the primary sterilization drainage bag and uses.
