Description

A kind of drain of open trauma of chest is applied ointment or plaster

Technical field

This utility model relates to a kind ofly can carry out chest open war first aid of wound and applying ointment or plaster of treatment.

Background technology

Thoracic trauma is a lethal main wound reason in the modern life, and the chest war wound then is a lethal main cause on the battlefield.Open trauma of chest directly causes open hemothorax, pneumothorax or hemopneumothorax, and usually is associated with fracture of rib even many multistage fractures of rib cause " flail chest ".

Along with thoracic wall expansion and diaphram shrink, can produce negative pressure in the thoracic cavity during breathing, air enters in the lung by upper respiratory tract and bronchus.When the thoracic wall retraction, when diaphram relaxes, produce malleation in the lung gas is discharged from respiratory tract.Break and during the wound continuous openness, air will enter the thoracic cavity and change pleural pressure from wound when the thoracic cavity, air can't enter in the lung, causes pneumothorax at last, the pulmonary collapse.If wound surpasses tracheal diameter, the air that enters the thoracic cavity will surpass and enter the interior air of lung, thereby cause the body anoxia.The more important thing is that if wound forms flap valve, the air admission thoracic cavity can form huge tension force, thereby suppress in the air admission lung.Therefore, the air admission thoracic cavity causes can't eupnea, and the wounded will suffocate.If do not obtain timely, correct treatment, will directly threaten the wounded's life.

The Therapeutic Method of open trauma of chest is to close wound, avoids the air admission thoracic cavity.People adopt that kpetrolatum gauze etc. is tight to cover the development that wound is avoided pneumothorax more before this.But these methods can not form a path of discharging gas in the thoracic cavity or liquid.Little wound, the someone advises covering wound with condom, cuts off osculum in the distally, to allow air scavenge in the thoracic cavity.Big wound can adopt plastics or rubber gloves to cover wound, cuts off the osculum aerofluxus at the fingerstall far-end.The problem of these methods is that the cut size of cutting off is wayward, and too little can not discharge gas smoothly, and the too big air that then may make oppositely enters the thoracic cavity by cut.United States Patent (USP) No. 4541426 (1985) designs a kind of dressing, the ground floor water-swellable, and second layer chance water does not expand or reduces than the ground floor expansion.Thisly apply ointment or plaster usefully, but can not provide air outlet slit for reducing pleural pressure to concerning the thoracic wall open injury.

Therapeutic Principle at open trauma of chest is clinically: 1. the normal morphology and the motion that recover thoracic wall; 2. replenishment of blood content and antibody restrain; 3. in time handle opening and tension pneumothorax.Correspond to the Therapeutic Principle, 1. need chest dressing waterproof accordingly, gas and seal thoracic trauma, recover the seal in thoracic cavity; 2. need special-purpose rib belts when merging fracture of rib and stablize thorax, promote normal the breathing to recover; 3. need promptly carry out the closed drainage of pleural cavity operation, promote lung to open again; 4. need liquid make-up, even the treatment of blood transfusion shock.Yet it is the comparison difficulty that the emergency aid and treatment that carries out this type of the wounded under contingency condition needs specialist, special surgical apparatus etc., and particularly under war condition, therapeutic time that may be urgent also can't guarantee.

At present, the material that is used to seal open trauma of chest clinically is the thick gauze of bulk of liner multilamellar kpetrolatum gauze, carries out rib with the fabric pectoral girdle of bull in addition and fixes.The improved procedure that carries out the closed drainage of pleural cavity operation is more, the applicant's utility model patent " war, the portable integral type pleural cavity closed drainage device of the wound " (patent No.: 200420057888.4) adopt the bushing type puncture drainage apparatus of band puncture nook closing member can comparatively fast finish operation technique.But this type of technology is applicable to the hemopneumothorax that the chest closed injury causes etc. more.The main material that carries out fracture of rib is still various pectoral girdles or Elastic bandage, also has to adopt the hard material of semidefinite form to be pasted on fixedly person of thorax injury.

Wound closure no matter be traditional dressing such as gauze, Cotton Gossypii etc., also or materials such as new pattern compress such as chitosan, hydrogel, its main purpose all with wound closure, promote wound healing, the restriction edema reduces hemorrhage, ease the pain the oxygen of improvement tissue, moisture content exchange etc.The needed dressing function of open trauma of chest is different therewith, and what in emergency circumstances need is tight wound closure, avoids the gas wound of arbitrarily coming in and going out, and keeps intrathoracic negative pressure, belongs to the successive treatment category as for other functions of dressing.Therefore the dressing that needs is different with traditional dressing.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aim to provide and a kind ofly can close open trauma of chest, discharge thoracic cavity gas or liquid, carry out autohemic recovery, filtration, feedback in case of necessity, can assist fixedly thorax, the drain that is beneficial to the stable open trauma of chest of thorax is applied ointment or plaster.

The implementation of this utility model purpose is, a kind of drain of open trauma of chest is applied ointment or plaster, constitute by coarctate hydrophobic material application layer 4, laying 2, rigid plastics support 3, laying 8, the stickup film 1 that contains pressure sensitive adhesive, the conduction hole 5 of applying ointment or plaster that the centre has external drain flexible pipe 7 to be communicated with, the conduction hole 5 of applying ointment or plaster is provided with unidirectional flap valve 6, contain pressure sensitive adhesive stickup film 1 area greater than laying 2,8 and between the area of rigid plastics support 3.

For keeping cleaning, the health of hydrophobic material application layer 4, the protection sheet of pasting film is arranged on the hydrophobic material application layer 4.

When using this utility model; tear the protection sheet of pasting film; hydrophobic material application layer 4 is covered on the wound; apply ointment or plaster conduction hole 5 over against the wound center; press the y direction sign of rigid plastics support 3; move towards parallel with rib, the stickup film 1 that contains pressure sensitive adhesive is pasted complete flap coverage with normal skin.Increase with intrathoracic pressure power, the unidirectional flap valve 6 on the conduction hole 5 of applying ointment or plaster is opened, and intrathoracic gas or liquid flow to external drain flexible pipe 7 from the conduction hole 5 of applying ointment or plaster.When intrathoracic pressure power reduced, air can not enter the thoracic cavity from draining hole.
