Abstract
The invention relates to a pulse fluid closed negative-pressure drainage system which is suitable for drainage of various acute and chronic wounds and wound cavities in the clinical medical treatment, and the addition of a pulse liquid system controlled by a controller for the closed negative-pressure drainage system not only introduces the concept of closed antibiotic irrigation, but also generates regular negative pressure alternation in negative pressure drainage materials according to a fluid flow. The liquid system is a pulse type, and is capable of controlling time at will. The liquid system retains the advantages of the negative-pressure drainage system, as well as overcomes the defects that blocking easily happens, especially that joints of negative pressure conduits in parallel connection are easy to be blocked by blood crusts or necrotic tissues; medical foam composite materials harden in short time and are out of action, and the system needs to be placed after several operations; blocky drains which possibly block a drainage pipe are obstructed by foam composite materials and cannot be effectively eliminated; the active solutions cannot be adopted for bleeding and infection of wounds and wound cavities; and specific observation indexes for determining whether the system is smooth or not are unavailable.

The concrete technical scheme of native system medical bio foamed materials is, foam material for medical use is the foam type synthetic material, and composition is a polyvinyl alcohol, and outward appearance is just as sponge, its inner dense cloth hole that communicate with each other in a large number, the about 0.2-1 millimeter of diameter.The negative pressure pipe that the foam material for medical use parcel is two, four liquid conduits, per two liquid lines are positioned at the both sides of a negative pressure pipe.Described pipe foam material for medical use wrapping portion all is with side opening, and the negative pressure pipe can pass through the breeches pipe parallel connection after going out material, links to each other with catcher, negative pressure source.Can prune when material is big, hour available a plurality of materials, the negative pressure pipe can pass by the punching of the normal skin of periphery, periphery that also can medical pad pasting closed drainage pipe.Can be during with a plurality of material by linking to each other with negative pressure source after the multistage Y tube parallel connection, negative pressure institute aspirate enters in the catcher.Equally, link to each other with controller after liquid line such as the method parallel connection.
The concrete technical scheme of controller is, the import and the outlet of liquid are arranged, form by a time controller, power supply and a closed type electromagnetic switch, time controller control can be set the time and the circulation of arbitrary current switch and carry out, pulsed electric current and closed type electromagnetic switch are joined switch opening are clocklike closed, and form the pulsed flow of liquid.Inlet tube links to each other with the medical delivery system of using always, and used liquid can be normal saline, also may add medicine such as antibiotic, hemorrhage etc.
The concrete technical scheme of medical pad pasting: tool has ventilative, water vapour permeability in the molecule valve function, can prevent the intrusion of sealing and antibacterial simultaneously.
Negative pressure source is the central negative pressure in the hospital, and the negative pressure pipe is introduced into transparent catcher before inserting central negative pressure, checks what and character of drain at any time.
The present invention has introduced sealing lavation theory by vacuum suction system being increased a pulsed liquid wash system, has not only overcome the weak point of negative pressure drainage system, and has more advantage.By the pulsed liquid wash, in time remove the drain in the negative pressure pipe, negative pressure system is kept clear constantly; By the pulsed liquid wash, make the medical foam synthetic material be in compression-recovery-compressive state, better removed and adsorbed blood, sepage and slough in the medical foam synthetic material and be unlikely harden hardening distortion of condensation material, local compression or local projection make that local organization exposes, drying, material can be placed to need the long time but not need change once in 5-7 days; Wound surface, hemorrhage, the infection conditions in wound chamber occur, can give actively counter-measure such as haemostatic medicament, antibiotic by liquid system; The negative pressure drainage system is to bigger, the not too hard block drain of quality is cut apart under the high negative pressure effect with moulding becomes graininess, hole through the foam synthetic material enters drainage tube, be absorbed into the collection container rapidly again, the bulk drain that may stop up drainage tube is then stopped by the foam synthetic material, can only be attached to the surface of foamed materials, leave body together at the replacing foamed materials, native system pulsed negative pressure makes the medical foam synthetic material be in compression-recovery-compressive state, can better cut apart block drain, the flushing of liquid can be decomposed in quickening just, thereby native system can be removed drain more efficiently; Whether frequently current that pulsed is arranged in the drainage tube are can better viewing system unobstructed; Moistening environment can better promote the growth of granulation, and it is dry downright bad not cause the tendon, the bone that expose to occur.
