Description
Technical field
This utility model relates to the various wound surface in the medical treatment, the drain in wound chamber, be applicable to that various wounds cause dampening that serious, bone or tendon exposed do not have fresh wound surface that appropriate method repairs or with the traditional method treatment quite a long time because of wound tissue, the normal concurrent infection of wound surface, the granulation edema is aging, cover fouling product on the wound surface, some bone, tendon that merges dry blackout is exposed, cicatrization on every side, the old wound surface that blood fortune is not good enough, and the drain in various wounds chamber.A concrete drainage system of forming by foam material for medical use, liquid controller, negative pressure catheter, liquid conduits, medical delivery system, medical negative pressure system (catcher and central negative potential source), medical pad pasting.
Technical background
The closed negative pressure drainage technology is to wrap up many side openings drainage tube with the medical foam synthetic material, utilizes the biological semipermeable membrane closed drainage district with molecule valve function again, makes it to be hedged off from the outer world, and connects the high negative pressure source, forms an efficient negative pressure drainage system.Compare with the tradition debridement of changing dressings, reach full wound surface drain, prevent to pollute and reduce the bacterial infection of wound surface, eliminate tissue edema, capillary lumen is significantly expanded, increase in density, improve local blood circulation, stimulate the granulation tissue growth, prevent cross infection, alleviate the patient suffering and alleviate medical personnel's workload.But there is following weak point in this system: easily stop up, the joint when particularly negative pressure catheter is in parallel is easily stopped up by blood crusts or slough; Vacuum suction makes the medical foam synthetic material be in compressive state, the hardening of hardening behind absorption blood, sepage and the slough is out of shape, and local compression or local projection make local organization exposure, drying, and drainage material is ineffective, need to change in five to seven days, some need be gone repeatedly operation and place this system; The negative pressure drainage system is cut apart under the high negative pressure effect with moulding block drain bigger, that quality is not too hard 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 leave body together at the replacing foamed materials attached to the surface of foamed materials; Wound surface, hemorrhage, the infection conditions in wound chamber occur, can only remove this system, do not respond actively measure; There is not a clear and definite observation index to system is unobstructed.
The utility model content
This utility model technical issues that need to address are by the closed negative pressure drainage system being increased the liquid system by liquid controller control impuls formula, to introduce sealing lavation theory.The existing closed negative pressure drainage system advantage of native system can overcome disadvantages of background technology again, and is also more efficient more practical.
Pulse liquid closed negative pressure drainage system body is a quadrate foam material for medical use (1), wrap up negative pressure catheter (3) and liquid conduits (4) in the foamed materials, liquid conduits inserts liquid controller (2), liquid controller inserts medical delivery system (5) again and forms a closed terminal, negative pressure catheter links to each other with the medical negative pressure system of being made up of catcher and central negative potential source (6), medical pad pasting (7) sticks on foam material for medical use (1) and goes up on the normal skin that reaches wound surface or wound chamber (8) periphery, form sealing, it is characterized in that in square foam material for medical use, inserting liquid conduits, liquid conduits is distributed in the both sides of negative pressure catheter, liquid conduits inserts liquid controller after going out foam material for medical use, liquid controller connects medical delivery system again, forms a closed terminal.
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 catheter 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 catheter.Described pipe foam material for medical use wrapping portion all is with side opening, and negative pressure catheter 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, negative pressure catheter 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 liquid controller after liquid conduits such as the method parallel connection.
The concrete technical scheme of liquid 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.
This utility model has been introduced sealing lavation theory by the closed negative pressure attraction 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 catheter, 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.
