Abstract
The invention provides a non-contact negative pressure wound treatment/debridement instrument which comprises a movable probe, connecting pipes, a liquid storage tank, a blowing generation device, a negative pressure generation device and a movable sealed box, wherein a negative pressure suction pipeline and a blowing pipeline are arranged in the movable probe; the negative pressure suction pipeline in the probe is connected with the liquid storage tank by the connecting pipe; the liquid storage tank is connected with the negative pressure generation device; the negative pressure generation device is provided with a negative pressure display device and a negative pressure control switch; the blowing pipeline in the probe is connected with the blowing generation device by the connecting pipe; and the liquid storage tank, the negative pressure generation device and the blowing generation device are placed in the sealed box. Blowing airflow and negative pressure suction airflow on the probe rotate due to tangential flow to form eddies; and on one hand, powerful suction of the rotating airflow clears up foreign bodies/necrotic tissues/seeped liquid and the like on a wound and on the other hand, the negative pressure prompts rapid heal of the wound. The non-contact negative pressure wound treatment/debridement instrument has a simple structure, implements double effects and can most effectively debride and prompt heal.
Description
Technical field
The present invention relates to a kind of noncontact negative pressure wound therapy/debridement instrument, the debridement drain of repairing especially for Wound/wound surface and the instrument of negative pressure treatment.
Background technology
Negative pressure drainage technology has following effect: 1. remove wound surface slough by its sucking action, the culture medium of eliminating bacteria existence; 2. reducing wound surface toxin absorbs; 3. absorb unnecessary liquid in tissue, reduce between tissue and press, alleviate edema; 4. stimulate local blood capillary proliferation, finally reach and accelerate the object that Wound/wound surface is repaired.Current disclosed depression drainage device is closed drainage device, as published Chinese utility model patent 98202614.5 comprises the compositions such as the locking device, conduit, negative pressure drainage device of wound closure.Because it needs locking device, Wound/wound surface is sealed, just can reach the object of utilizing negative pressure drainage, the Wound/wound surface sealing and create all skin histologies and must be closed device and cover, the compressing that is under pressure also will inevitably be because of negative pressure drainage time, thus cause new wound.On the other hand, this device can not be applied to many cases patient, easily causes cross infection.
Summary of the invention
The object of this invention is to provide a kind of noncontact negative pressure wound therapy/debridement instrument, thereby avoid closed negative pressure drainage device to bring the shortcoming of impressed pressure and cross infection to wound surface.
In order to reach this object, the technical solution adopted in the present invention is: comprise removable probe, depression generator, blowing generating means, negative pressure display device, negative pressure gauge tap, wind control switch, connection tube, fluid reservoir, closed box movably.Wherein, have negative pressure-pumping pipeline and blowing pipeline in removable probe, in probe, negative pressure-pumping system pipeline is connected with fluid reservoir by connection tube, and fluid reservoir is connected with depression generator, and negative pressure display device is connected with depression generator with negative pressure gauge tap; In probe, blowing pipeline is connected with blowing generating means by connection tube, and wind control switch is connected with blowing generating means; Fluid reservoir, depression generator, blowing generating means is positioned over movably in closed box.Wherein, in removable probe, have single or multiple negative pressure-pumping pipelines and single or multiple blowing pipeline, can be any space rule and geometry arrangement, wherein all pipeline opening aperture is unrestricted, shape can be arbitrary shape, and material can be soft or hard any avirulence material.Feature of the present invention is that depression generator generation negative pressure makes air-flow directed flow, thereby blowing device blows out air-flow that air-flow and negative pressure-pumping form and forms tangential flowing form one or more air-flow whirlpool between probe and wound surface, reaches the effect of removing wound surface foreign body/slough/sepage; Negative pressure-pumping probe does not contact with wound surface on the other hand, does not bring pressure to wound surface, but has again lasting suction function on wound surface, to reach the object of wound healing.Its removable closed box, can arbitrarily move, and for the patient of more different wound surface uses, has reduced cost; Simultaneously movably pop one's head in and do not contact with wound surface in application process due to it, avoided the generation of cross infection.
Accompanying drawings: Fig. 1 is the side cross-sectional views of noncontact negative pressure wound therapy instrument probe.
Fig. 2 is the ground plan of noncontact negative pressure wound therapy instrument probe.
Fig. 3 is the outside drawing of noncontact negative pressure wound therapy instrument.
In removable probe (1), have negative pressure-pumping pipeline (2) and blowing pipeline (3), negative pressure-pumping pipeline (2) is connected with fluid reservoir (5) by connection tube (4); Fluid reservoir (5) is connected with depression generator (6) by connection tube (4); On depression generator (6), be provided with negative pressure display device (7) and negative pressure gauge tap (8); In probe, blowing pipeline (3) is connected with blowing generating means (9) by connection tube (4); Blowing generating means (9) is provided with wind control switch (10); Fluid reservoir (5), depression generator (6) and blowing generating means (9) are placed on movably in closed box (11).
When concrete enforcement, regulate negative pressure-pumping air-flow size by controlling negative pressure gauge tap, by the clear and definite negative pressure numerical value of negative pressure display device, regulate and discharge air-flow size by wind control switch, discharge air-flow and negative pressure-pumping by blowing device and get up to form tangential flowing, air-flow is rotated form swirling air stream to reach the effect of debridement and wound healing simultaneously.
The invention is not restricted to the scope of embodiment, as long as can realize the swirling eddy suction method that does not contact wound surface, reach its technique effect, all within protection domain of the present invention.
Claims (5)
1. a noncontact negative pressure wound therapy/debridement instrument, include: in removable probe (1), have negative pressure-pumping pipeline (2) and blowing pipeline (3), negative pressure-pumping pipeline (2) is connected with fluid reservoir (5) by connection tube (4); Fluid reservoir (5) is connected with depression generator (6) by connection tube (4); On depression generator (6), be provided with negative pressure display device (7) and negative pressure gauge tap (8); Blowing pipeline (3) is connected with blowing generating means (9) by connection tube (4); Blowing generating means (9) is provided with wind control switch (10); Fluid reservoir (5), depression generator (6) and blowing generating means (9) are placed on movably in closed box (11).
2. according to having single or multiple negative pressure-pumping pipelines and single or multiple blowing pipeline in the removable probe described in claims 1, can be any space and geometry arrangement, pipeline aperture and shape are unrestricted, and material can be soft or hard any avirulence material.
