Description

The multiple spot negative pressure drainage device

Technical field

The present invention relates to a kind of medical negative pressure drainage device, particularly a kind of multiple spot negative pressure drainage device that is applicable to that the body surface Wound treating is used.

Background technology

Negative-pressure sealed drainage technology (being called for short VSD) is a kind of brand-new Therapeutic Method that promotes wound healing by controllable negative pressure, and be widely used in medically, the basic configuration of existing negative pressure drainage device comprises negative pressure source, drainage tube, the porous foam cushion, biological semipermeable membrane and drainage container, in the porous foam cushion, be provided with drainage tube, be distributed with a plurality of apertures on the drainage tube sidewall, during use, the porous foam cushion is placed on the wound surface, cover on the porous foam cushion with biological semipermeable membrane then, be enclosed in porous foam cushion and drainage tube on the human body together, the drainage tube other end is connected with drainage container by straight-through or multiple-pass joint, drainage container is connected with negative pressure source by conduit, connect negative pressure source, by negative pressure drainage, with the oozing of blood in the tissue of gathering in the drainage tube, sepage, liquefied material drains such as the fragment of tissue of liquefaction and necrosis and pus are to drainage container.

The major defect that the negative pressure drainage device of said structure exists is: in the use, when biological semipermeable membrane is enclosed in porous foam cushion and drainage tube on the human body together, between the drainage tube of biological semipermeable membrane edge and human body surface, unavoidably can there be certain clearance, make drainage tube and human body surface have poorly sealed situation, influenced the effect of negative pressure drainage.

Summary of the invention

The technical problem of solution required for the present invention is: provide a kind of and have good sealing property and be applicable to the multiple spot negative pressure drainage device that the body surface Wound treating is used.

For addressing the above problem, the technical solution used in the present invention is: described multiple spot negative pressure drainage device, comprise the PU Wound dressing, be placed with big sucker and at least two small suckers on PU Wound dressing surface, big sucker is positioned in the middle of the PU Wound dressing, small sucker is distributed in around the big sucker, all offer at least two plug aperture on big sucker and the small sucker, the head plug at the head plug of drain outer tube and bullhead conduit two ends is cone shape, the head plug can insert and be sealedly attached in the plug aperture, drain outer tube tail end is connected with drainage container by straight coupling, and drainage container is connected with negative pressure source by conduit; During work, the drain outer tube is connected with big sucker, and each small sucker links to each other in twos by the bullhead conduit, and last and big sucker is communicated with, and the multiple spot attraction by big sucker and small sucker gathers liquefied material to drainage container by the drain outer tube.

Further, aforesaid multiple spot negative pressure drainage device, wherein, the head plug at the head plug of drain outer tube and bullhead conduit two ends is the cone shape of band dentation.

Further, aforesaid multiple spot negative pressure drainage device wherein, offers three plug aperture on the big sucker, offers two plug aperture on each small sucker.

The invention has the beneficial effects as follows: during use, biological semipermeable membrane covers on the PU Wound dressing, PU Wound dressing and big sucker and small sucker are enclosed on the human body, the head plug only punctures the biological semipermeable membrane that covers on the plug aperture, can't destroy the biological semipermeable membrane that covers on PU Wound dressing and big sucker and the small sucker, thereby make the good seal of maintenance between PU Wound dressing and the wound surface, avoided the gas leakage problem of drainage tube sponson in the negative pressure drainage work, in addition, adopt big sucker and small sucker multiple spot to attract liquefied material, can be better with wound tissue liquid, liquefied materials such as pus and blood excrete, improve the negative pressure drainage effect of negative pressure drainage device, prolonged the service life of negative pressure drainage device.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment technical solutions according to the invention are described in further detail.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the multiple spot negative pressure drainage device, comprise PU Wound dressing 1, be placed with big sucker 6 and four small suckers 4 on PU Wound dressing 1 surface, big sucker 6 is positioned in the middle of the PU Wound dressing 1, four small suckers 4 are distributed in big sucker 6 all around, in actual applications, the quantity of small sucker 4 can arrange as required, offer at least two plug aperture 61 on the big sucker 6, offer at least two plug aperture 41 on each small sucker 4, the head plug 31 of drain outer tube 3 is the cone shape of band dentation, and the head plug at bullhead conduit 2 two ends is identical with the head plug 31 of drain outer tube 3, and the head plug can insert and be sealedly attached in arbitrary plug aperture, drain outer tube 3 tail ends are connected with drainage container 7 by straight coupling 32, and drainage container 7 is connected with negative pressure source 9 by conduit 8.
