Abstract
The utility model discloses a mushroom cuff type chest drainage tube which comprises a drainage guide tube, wherein one end of the drainage guide tube is provided with dual air sacs, so that a dual-air-sac mushroom structure can be formed; a retaining clip used for fixing and hemostasis by compression is arranged at one end close to the tail part of the small mushroom-stem-shaped air sac along the outer tube wall of the drainage guide tube; the other end of the drainage guide tube is detachably connected with a duckbill valve which penetrates into a ball body; an inner sealed cover is sleeved on the outer side of the duckbill valve, and an outer sealed cover is arranged outside the inner sealed cover and is connected with the ball body. The mushroom cuff type chest drainage tube provided by the utility model can effectively meets the requirements of field first aid on transferring and carrying of a thoracic closed drainage instrument, wide application and the like; due to the dual-sac structure of the mushroom cuff, the mushroom cuff type chest drainage tube can be effectively suitable for pressure difference between the dual sacs when tissues in the chest and intercostal space are fixed so as to facilitate fixation of inner chest wall side tissues; the mushroom cuff type chest drainage tube is particularly applicable to treatment on pneumothorax and hemopneumothorax caused by acute trauma.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of mushroom cuff formula intrathoracic drain.
Background technology
Thoracic trauma is the higher wound of incidence rate in war, natural disaster and thunder bolt.Thoracic trauma mainly contains fracture of rib and lung contusion, and these two kinds of traumatic conditions all can cause hemopneumothorax.Pneumothorax refers to that gas enters pleural space, causes pneumatosis state, is called pneumothorax.Pneumothorax is divided into again: closed pneumothorax, open pneumothorax, tension pneumothorax.Hemopneumothorax refer to pneumothorax hemorrhage be blood vessel in pleural adhesion band by due to tear fracture.When acute bleeding, the discomfort such as that the wounded can occur is uncomfortable in chest, tachypnea, dyspnea.In addition, hemothorax more than middle amount can be accumulated because of thoracic cavity inner blood, and compressing lungs, are affected ventilatory function, cause respiratory dysfunction, bleeding profusely in pleural space, can oppress vertical diaphragm simultaneously, make vertical diaphragm displacement, cause obstruction of blood return, increase the weight of circulatory function obstacle.As rescued not in time, can threat to life.Closed drainage of pleural cavity is the effective ways of aerothorax/hydrops of causing for the treatment of a variety of causes.
Yet can implement in time closed drainage of pleural cavity operation be to determine that first aid is successfully crucial.In thoracic trauma treatment both at home and abroad, all emphasized the necessity of early stage row closed drainage of thoracic cavity operation.At present army defends the employing measure of diligent first aid institute for to use scalpel closed drainage of pleural cavity, and professional technique is strong, and complicated operation, time-consuming is difficult to grasp, and the thoracic duction instrument volume using greatly, Portable belt not.These features make conventional closed drainage of pleural cavity method be difficult to be applied to the first aid in on-the-spot battlefield.According to statistics, in the lethal patient of the annual 150000 routine wound of the U.S., the lethal patient 25% of thoracic trauma.The Wenchuan violent earthquake that on May 12nd, 2008 occurs, by 12 o'clock on the 11st August, Wenchuan County in Sichuan earthquake confirmed that 69225 people are wrecked, 374640 people are injured, missing 17939 people.At present, elimination earthquake is seen almost impossible from reality, and reduce earthquake casualties harm, have very important meaning.When review, the first aid of summary Wenchuan earthquake, find that China's trauma care level and developed country remain certain gap, not only relevant with relevant first-aid knowledge with shortage system treatment program, and have much relations with easy to carry, simple to operate, the effective instant first-aid equipment of shortage.
Yet current existing percutaneous puncture insertion type pleural cavity closed drainage device, through PubMed retrieval, does not find foreign literature report.Yet, the domestic improvement main manifestations to percutaneous puncture insertion type pleural cavity closed drainage device is: drainage tube is fixing is all sacculus and outer baffle designs in adopting, between interior sacculus and outer baffle, exist larger apart from gap, this is for the wounded of different thoracic wall thickness, and fixing of drainage tube is tight not.Drainage bag is the drainage bag of unidirectional valve, and unidirectional valve has only limited backflow and the pollution of drainage bag, but above-mentioned these improve the needs of field first aids such as fundamentally not meeting the transhipment of closed drainage of thoracic cavity operation instrument is portable, wide accommodation.
Summary of the invention
The defect or the deficiency that in order to solve above-mentioned prior art, exist, the purpose of this utility model is, a kind of mushroom cuff formula intrathoracic drain is provided, this drainage tube is easy to operate, can disposablely use, and Financial cost is cheap.
In order to realize above-mentioned technical assignment, this utility model adopts following technical scheme to be achieved:
A kind of mushroom cuff formula intrathoracic drain, comprise drainage catheter, in one end of drainage catheter, be provided with two air bags, it is characterized in that: the large cuff that this pair of air bag is a mushroom lid type and the little cuff of a mushroom handle shape, large cuff is combined the mushroom double-air sac structure of formation with little cuff; In the one end that approaches the little cuff afterbody of mushroom handle shape, and be provided with for fixation clamp fixing, hemostasis by compression along drainage catheter outer tube wall, the other end of drainage catheter is detachable is connected with duckbill valve, duckbill valve is deeply to spheroid, inner, outside duckbill valve is socketed with inner sealing lid, and the outer setting of inner sealing lid has sealing external cover, and sealing external cover is connected with spheroid; Along drainage catheter tube wall, be provided with the gas tube being connected with large cuff and little cuff respectively, gas tube is in series with pilot balloon, check valve successively.
This utility model also has following other technologies feature:
Described fixation clamp is that double card cover is embedded in drainage catheter tube wall outside.
The top of described sealing external cover is provided with upper cap, in spheroid bottom, is provided with lower cover cap.
Upper the installing in surface of the described large cuff far-end of close mushroom lid type is equipped with several conduction holes, and the cross section of close large cuff near-end is rectangle.
The volume of described spheroid is 300ml.
This utility model compared with prior art, has following other technologies advantage:
(1) adopt mushroom cuff formula intrathoracic drain of the present utility model, simplified closed drainage of thoracic cavity operation operation, be easy to grasp and promote, army's Primary medical worker can be used after brief training.(2) adopt intrathoracic drain of the present utility model easy and simple to handle, step is simple, can 1 ?complete in 2 minutes and put pipe, fixing and drain.(3) chest drainage pipe volume of the present utility model is little, is easy to carry, and can equip basic health company.(4) use the not receptor site impact of this intrathoracic drain, be particularly suitable for the wounded in wartime after send transhipment.(5) mushroom-shaped cuff is convenient to adapt in fixing thoracic cavity and the pressure differential producing between double cuff when intercostal organizes.(6) by respectively large cuff and little cuff being carried out to unidirectional inflation, can effectively realize two pressure balances between cuff.(7) design of detachable blood negative pressure drainage device, facilitates medical personnel to operate.
